Technical Field

The present invention relates to the field of electronic devices, and in particular, to an image capturing apparatus.

Background

The specification of lenses in cameras is getting higher and higher, and a plurality of single-lens reflex lenses are put into a shield camera for use. However, most slms are sensitive to temperature, and an excessively high temperature and an excessively low temperature cause the slms to operate abnormally.

This is mainly because the lens is realized by the internal self-contained motor and worm gear when zooming. The running fit of the worm gear requires the presence of a lubricant, which is mostly temperature sensitive. The more precise the lens is, the more sensitive it is to temperature.

At present, the common commercial single-lens reflex lens generally has the working temperature of-10 to 50 ℃. Whereas typical shield cameras are typically used at temperatures of-30-60 degrees celsius. The single lens reflex is put into the protective cover, and the protective cover is also provided with heating elements such as a gun camera, a power supply assembly and the like. The temperature rise of the shield is generally 10-15 ℃, that is, when the shield works at-30-60 ℃, the ambient temperature of the internal lens is-20-75 ℃, which is far larger than the working temperature range of the current commercial single-lens reflex lens.

Fig. 1 is a schematic configuration diagram of a conventional imaging apparatus. As shown in fig. 1, the main heating elements in the housing 1 are a gun-shaped camera 2, a power supply assembly 3 (for supplying power to the whole camera); the temperature-sensitive element, the lens component 4, basically does not generate heat, and the heat comes from the gunlock and the power supply component. The existing camera device mainly cools the whole shield cavity by blowing cold air to the inside of the shell 1 through the refrigerating device 7, most of cold energy of the cold air is absorbed by the camera and the power supply assembly, the brought effect is mainly that the temperature of the gunlock and the power supply assembly is reduced, and the cooling effect on the lens which is a non-heating element is not ideal.

Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings, in which like reference numerals refer to like parts throughout.

"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.

For the sake of simplicity, the drawings are only schematic representations of the parts relevant to the invention, and do not represent the actual structure of the product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled.

Fig. 2 is a schematic configuration diagram of a first embodiment of the image pickup apparatus of the present invention. As shown in fig. 2, the present invention provides an image pickup apparatus including: the camera comprises a shell 1, a gun-shaped camera 2 arranged in a cavity of the shell 1, a power supply component 3 and a lens component 4, wherein the lens component 4 is arranged on one side of the gun-shaped camera 2, which is far away from the power supply component 3.

The cavity of the shell 1 is divided into a temperature control cavity 10 and a heating cavity 20 by a first dividing wall 31 in a sealing way, wherein, a temperature sensitive element, a lens component 4 is positioned in the temperature control cavity 10, a heating element, a gun-shaped camera 2 and a power supply component 3 are positioned in the heating cavity 20, the first dividing wall 31 is formed by heat insulation materials, the inner edge of the first dividing wall 31 is attached to the outer surface of an electronic element, the outer edge of the first dividing wall 31 is attached to the inner surface of the shell 1 to form a sealing separation between the temperature control cavity 10 and the heating cavity 20, and the heat generated by the heating element in the heating cavity 20 is prevented from being conducted into the temperature control cavity 10, so that the ambient temperature in the temperature control cavity 10 is prevented from being influenced by the heating element.

In this embodiment, the heating elements, i.e., the gun camera 2 and the power supply assembly 3, which will cause the temperature inside the casing to rise, and the temperature-sensitive elements, i.e., the lens assemblies, which have a high requirement on the temperature inside the casing are respectively disposed in different cavities, and the cavities are sealed and separated by a heat insulating material, so that the heat emitted by the heating elements is prevented from affecting the temperature inside the whole casing, especially the heat of the heating elements is prevented from affecting the temperature inside the temperature-control cavity, and the influence of the heating elements on the temperature-sensitive elements is eliminated, and even if there is no heat dissipating element, the ambient temperature of the lens assemblies is better than that of the cavities without division.

Further, the present embodiment divides the interior of the housing into cavities, so that the temperature control of the electronic components in the image pickup device can be refined to local control. For example, the heat dissipation element may be disposed in the heat generating cavity to more efficiently reduce the temperature rise caused by the heat generating element, thereby reducing the ambient temperature inside the housing of the image pickup device from the source. Or, the heat dissipation element can be arranged in the temperature control cavity to accurately control the environmental temperature of the lens assembly, and the temperature control cavity in which the lens assembly is located is less affected by the heating element because the lens assembly and the heating element are sealed and separated by the heat insulation material, so that the heat dissipation efficiency of the heat dissipation element to the temperature control cavity is far greater than the heat dissipation efficiency of the whole shell.

In order to realize the sealed separation of the first separation wall 31 to the internal cavity of the housing, the inner edge of the first separation wall 31 is attached to the outer surface of the electronic component (the heating element or the temperature-sensitive element), while the outer edge is attached to the inner surface of the housing, and the gap between the electronic component and the inner surface of the housing is fully filled to realize the sealed separation of the internal cavity of the housing, thereby realizing the purpose of blocking the influence of the heat emitted by the heating element on the environmental temperature of the temperature-sensitive element.

As shown in the front view and the exploded view of the first embodiment of the image pickup apparatus of the present invention shown in fig. 3a and 3b, the first partition wall 31 may be disposed around the lens assembly 4, and thus, the first partition wall 31 may be formed of one or more pieces of heat insulating material for the convenience of installation and for sufficiently filling the gap between the electronic components and the inner surface of the housing. In the example shown in fig. 3a, the first partition wall 31 may include at least adiabatic materials 31a, 31b, 31c, and 31d, and each adiabatic material may be formed in a different shape according to a position. For example, the first partition wall first block 31a may be formed in a U shape that is held at the upper portion of the gun camera 2 from the top of the gun camera 2 so as to be filled between the housing 1 and the gun camera 2 from the top and both sides of the gun camera 2, and the heat insulating material 31c, 31d is filled between both sides of the first partition wall first block 31a and the inner surface of the housing 1 so as to be formed in a rectangular parallelepiped shape.

Fig. 4 is a schematic configuration diagram of a second embodiment of the image pickup apparatus of the present invention. As shown in fig. 4, the present embodiment discloses an image pickup apparatus, which is added with a temperature adjustment device 50 as a heat dissipation element on the basis of the first embodiment, and the temperature adjustment device 50 is arranged in the temperature control chamber 10 and is used for adjusting the temperature in the temperature control chamber 10 to be within a predetermined temperature range.

In the present embodiment, the temperature adjusting object of the temperature adjusting device 50 is the temperature control chamber 10, not the whole inside of the housing, and the adjusting efficiency of the temperature adjusting device 50 is significantly improved due to the reduction of the space volume. Further, due to the existence of the first partition wall 31, the influence of the heating element on the ambient temperature in the temperature control chamber 10 is greatly prevented, so that the ambient temperature in the temperature control chamber 10 does not greatly exceed the predetermined temperature range (the normal operating temperature range of the temperature sensitive element), thereby greatly reducing the workload of the temperature adjustment device 50.

In the present embodiment, the temperature adjustment device 50 may have only a temperature reduction function, or both the temperature reduction and temperature increase functions. Correspondingly, the temperature control chamber 10 further has a temperature sensor therein, and the controller turns on or off the temperature adjusting device 50 according to the measured temperature of the temperature sensor.

When the temperature adjustment device 50 has both the temperature reduction and temperature increase functions, in the image pickup device of the present embodiment, the inner surface of the housing 1 may not need to be additionally provided with an insulating material. When the temperature in the temperature-controlled chamber 10 is higher than the predetermined temperature range due to the heat emitted from the gun-shaped camera 2 and the power supply module 3 or the ambient temperature, the controller controls the temperature-adjusting device 50 to start cooling down to lower the temperature in the temperature-controlled chamber 10 to be within the predetermined temperature range. Likewise, when the temperature of the temperature controlled chamber 10 is lower than the predetermined temperature range due to the ambient temperature, the controller controls the temperature adjusting device 50 to start the temperature rise to raise the temperature inside the temperature controlled chamber 10 to be within the predetermined temperature range. And when the temperature in the temperature-controlled chamber 10 is within the predetermined temperature range, the temperature-adjusting device 50 may not be activated.

In a preferred embodiment, the temperature adjustment device 50 may be implemented as a semiconductor Cooler (Thermo Electric Cooler), and when a direct current passes through a couple composed of two semiconductor materials, one end absorbs heat and the other end releases heat, so that the temperature of the temperature adjustment device 50 can be controlled to be lowered or raised according to the direction of the current.

The temperature adjustment device 50 includes a first heat dissipation surface 51 and a second heat dissipation surface 52, the heat dissipation tendencies of the first heat dissipation surface 51 and the second heat dissipation surface 52 are opposite, that is, when the first heat dissipation surface 51 absorbs heat, the second heat dissipation surface 52 releases heat, and when the first heat dissipation surface 51 releases heat, the second heat dissipation surface 52 absorbs heat.

Accordingly, the temperature adjustment device 50 is fixed to the housing 1, such that the first heat dissipation surface 51 is disposed in the temperature control chamber 10, and the second heat dissipation surface 52 is disposed outside the temperature control chamber 10, and the first heat dissipation surface 51 is controlled to cool or heat the temperature control chamber 10 by controlling the current direction of the temperature adjustment device 50.

In a preferred embodiment of the temperature adjustment device 50 of the image pickup apparatus of the present invention shown in fig. 5 and 6, it further includes:

a first heat sink 61, the bottom surface of the first heat sink 61 being attached to the first heat dissipation surface 51, the area of the bottom surface of the first heat sink 61 being equal to or larger than the first heat dissipation surface 51;

a second heat sink 62, wherein the bottom surface of the second heat sink 62 is attached to the second heat dissipation surface 52, and the area of the bottom surface of the second heat sink 62 is larger than or equal to that of the second heat dissipation surface 52;

and the heat insulation foam 63, wherein the heat insulation foam 63 surrounds the temperature adjusting device 50 from the periphery and is positioned between the bottom surface of the first radiating fin 61 and the bottom surface of the second radiating fin 62.

In combination with the above, as shown in the structural diagram of the bottom surface of the housing shown in fig. 7a, the housing 1 further includes a heat dissipation opening 1a, and in combination with the structural diagram of the bottom surface of the housing shown in fig. 7b, where the temperature adjustment device 50 is installed, the first heat dissipation surface 51 faces the inside of the cavity of the housing 1, and the second heat dissipation surface 52 faces the outside of the housing 1 and is exposed to the heat dissipation opening 1 a. Accordingly, the second heat sink 62 is fixed to the outside of the housing 1.

Thus, the first heat dissipating surface 51 absorbs or dissipates heat inside the temperature controlled chamber 10 through the first heat dissipating fins 61, and the second heat dissipating surface 52 dissipates or absorbs heat outside the case 1 through the second heat dissipating fins 62. The first radiating fin 61 and the second radiating fin 62 are isolated by the heat insulation foam 63, and heat is not mutually transferred.

The first heat dissipation surface 51 and the bottom surface of the first heat dissipation plate 61 may be filled with a thermal interface material, and correspondingly, the second heat dissipation surface 52 and the bottom surface of the second heat dissipation plate 62 may also be filled with a thermal interface material.

In a specific example, the fins of the first cooling fin 61 are distributed at equal intervals, the thickness of the fins is controlled to be 0.5-2mm, the interval between adjacent fins is controlled to be 1-5mm, and the depth of the fins is controlled to be 5-50 mm. The fins of the second radiating fins 62 are distributed at equal intervals, the thickness of the fins is controlled to be 0.5-3mm, the interval between adjacent fins is controlled to be 3-15mm, and the depth of the fins is 20-80 mm. The thickness of the heat insulation foam 63 can be controlled within 2-8 mm.

The overall volume of the first heat sink 61 should be smaller than the volume of the second heat sink 62 due to space constraints inside the image pickup device, and accordingly, the fin pitch, thickness, depth, etc. of the first heat sink 61 may each be smaller than the fin pitch, thickness, depth, etc. of the second heat sink 62.

As shown in fig. 5 and 6, the second heat sink 62 may further include a sealing groove 621 on a bottom surface thereof to receive a sealing ring 622 for sealing contact with the bottom surface of the case 1. Wherein the sealing groove 621 surrounds the thermal insulation foam 63. In the present embodiment, the area of the heat dissipation hole 1a should be smaller than the area of the bottom surface of the second heat dissipation plate 62, but may be larger than or equal to the area of the bottom surface of the first heat dissipation plate 61, and the temperature adjustment device 50 is fixedly connected to the bottom surface of the housing 1 through the screw hole at the end corner of the second heat dissipation plate 62.

In order to further reduce the internal space of the image pickup device occupied by the first heat radiation fins 61 and improve the heat radiation efficiency of the temperature adjustment device 50, in the third embodiment of the image pickup device shown in fig. 8, it further includes:

the vortex fan 70, the air inlet 71 and the air outlet 72 of the vortex fan 70 are perpendicular to each other, the air inlet 71 is adjacent to the first heat sink 61 or the first heat dissipating surface 51, and the air outlet 72 is disposed vertically upward so as to face the side edge of the lens assembly 4. That is, the air outlet 72 and the air inlet 71 are perpendicular to each other.

In a preferred embodiment, the air outlet 72 is adjacent to the inner surface of the housing 1, and the air outlet 72 forms an acute angle with the inner surface of the housing 1 to form an annular air flow within the housing 1.

Different from the conventional axial flow fan, because the air outlet 72 of the vortex fan changes the angle between the air outlet direction and the air inlet direction, so that the air outlet direction forms an acute angle with the inner surface of the housing 1, and the air flow direction discharged from the air outlet 72 forms an obtuse angle with the inner surface of the housing 1, the air flow is not reversely rebounded by the inner surface of the housing 1, but is guided by the inner surface of the housing 1 to flow, so that the annular air flow surrounding the lens assembly 4 as shown by the arrow in fig. 8 is formed along the inner surface of the housing 1, the distribution of the annular air flow is more uniform, so that the annular air flow can fully surround the temperature-sensitive element, and the temperature reduction or temperature rise of the temperature control chamber 10, particularly the lens assembly 4, is fully and uniformly realized.

And the fin pitch of the first heat radiation fins 61 can be further reduced, for example, adjusted to 1-5mm, due to the heat radiation function of the eddy fan 70.

The clearance between the air inlet 71 of the vortex fan 70 and the first cooling fin 61 is kept within 50 mm; the fins of the first heat sink 61 are directed toward the air inlet 71 of the vortex fan 70; the lens assembly 4 is spaced from the housing over a full range of positions of the vortex fan 70 for air circulation in the chamber, with a minimum clearance of about 10 mm.

The lens assembly 4 includes a lens 41 and a focus adjustment portion 42, and the lens 41 is attached to the side of the gun camera 2 facing away from the power supply assembly 3 through the focus adjustment portion 42.

The temperature control cavity 10 is further divided into a first temperature control cavity 11 and a second temperature control cavity 12, the focal length adjusting part 42 is located in the second temperature control cavity 12, the lens 41 is located in the first temperature control cavity 11, a second partition wall 32 is formed between the first temperature control cavity 11 and the second temperature control cavity 12, the length of the second temperature control cavity 12 corresponds to that of the focal length adjusting part 42, the second partition wall 32 is formed by a heat insulating material, the inner edge of the second partition wall 32 is attached to the outer surface of the electronic component, the outer edge of the second partition wall 32 is attached to the inner surface of the shell 1, and the second partition wall 32 forms a sealed partition between the first temperature control cavity 11 and the second temperature control cavity 12 so as to accurately distribute the temperature sensitive focal length adjusting part 42 into the second temperature control cavity 12.

In this embodiment, the heating elements, i.e., the gun camera 2 and the power supply assembly 3, which will cause the temperature inside the casing to rise, and the lens assembly 4, which is a temperature sensitive element having a high requirement on the temperature inside the casing, are arranged in different cavities, and the cavities are sealed and separated by a heat insulating material, so that the heat emitted by the heating elements is prevented from affecting the temperature inside the whole casing, and further the influence of the heating elements on the temperature sensitive element is eliminated, and the ambient temperature of the temperature sensitive element is better than that without dividing the cavities even without the heat radiating elements.

The further division of the temperature-controlled chamber 10 can realize accurate division of temperature-sensitive elements, and in the imaging apparatus of the present embodiment, the most sensitive to the ambient temperature is the focal length adjustment portion 42 in the lens assembly 4, and thus, the temperature-controlled chamber 10 in which the lens assembly 4 is included is further divided into the first temperature-controlled chamber 11 including the lens 41 less sensitive to the temperature and the second temperature-controlled chamber 12 including the focal length adjustment portion 42 more sensitive to the temperature, and the length of the second temperature-controlled chamber 12 can be set to correspond to the length of the focal length adjustment portion 42, so that only the focal length adjustment portion 42 can be included in the second temperature-controlled chamber 12, and other electronic elements not requiring accurate temperature control, except for the heat-generating gun-shaped camera 2, the power supply assembly 3, and the focal length adjustment portion 42 sensitive to the temperature, are arranged in the first temperature-controlled chamber 11 or the heat-generating chamber 20. This further provides a precondition for local temperature control for the focal length adjustment section 42.

By further fine partitioning of the temperature-controlled cavity, the temperature control for the image pickup apparatus of the present embodiment can be refined to local control. For example, the heat dissipation element may be disposed in the heat generating cavity to more efficiently reduce the temperature rise caused by the heat generating element, thereby reducing the ambient temperature inside the housing of the image pickup device from the source. Or, can set up heat dissipation component in second accuse temperature chamber to focus adjustment portion's ambient temperature is controlled accurately, because second accuse temperature chamber and first accuse temperature chamber, generate heat and all seal up with thermal insulation material and separate between the chamber, therefore focus adjustment portion locates accuse temperature chamber receives heating element's influence less, then heat dissipation component can be far greater than to the inside radiating efficiency of whole casing to the radiating efficiency in accuse temperature chamber, and reduce the volume automatic control temperature chamber 10 in second accuse temperature chamber that needs temperature control to second accuse temperature chamber 12, then can further improve heat dissipation component's radiating efficiency and radiating effect.

In the embodiment shown in fig. 9, the second temperature-controlled chamber 12 is located between the first temperature-controlled chamber 11 and the heat generation chamber 20, that is, the second temperature-controlled chamber 12 is spaced from the heat generation chamber 20 by the first partition wall 31 while being spaced from the first temperature-controlled chamber 11 by the second partition wall 32, which is formed by the structure of the image pickup apparatus of the present embodiment. Another embodiment of the present invention can also be implemented such that the first temperature-controlled cavity 11 is located between the second temperature-controlled cavity 12 and the heat-generating cavity 20. The second temperature-controlled chamber 12 is spaced apart from the heat generation chamber 20 and the first temperature-controlled chamber 11 by a second partition wall 32. The first temperature-controlled chamber 11 may also serve as a partition for partitioning the second temperature-controlled chamber 12 from the heat generation chamber 20.

In order to realize the sealed separation of the first partition wall 31 and the second partition wall 32 from the internal cavity of the housing, the inner edges of the first partition wall 31 and the second partition wall 32 are attached to the outer surface of the electronic component (the heating element or the temperature-sensitive element), while the outer edges are attached to the inner surface of the housing, so that the gap between the electronic component and the inner surface of the housing is fully filled to realize the sealed separation of the internal cavity of the housing, and the purpose of preventing the heat emitted by the heating element from influencing the environmental temperature of the temperature-sensitive element is realized. The structure of the first partition wall 31 may be the same as the embodiment shown in fig. 3a, 3 b.

As shown in the front view and the exploded view of the fourth embodiment of the image pickup apparatus of the present invention shown in fig. 10a and 10b, the second partition wall 32 may be provided around the lens 42 or the focus adjustment section 42, and therefore, the second partition wall 32 may be formed of one or more pieces of heat insulating material for the convenience of installation and for sufficiently filling the gap between the electronic component and the inner surface of the housing. In the example shown in fig. 10a, the second partition wall 32 may include insulation materials 32a, 32b, 32c, and 32d, and each insulation material may be formed in a different shape according to a location. For example, the second partition wall first block 32a is formed in a U shape held at the top of the lens assembly 4 from the top of the lens assembly 4, and the heat insulating materials 32c, 32d are filled between both sides of the second partition wall first block 32a and the inner surface of the housing 1, formed in a rectangular parallelepiped shape.

The temperature control cavity 10 is further divided into a first temperature control cavity 11 and a second temperature control cavity 12, so that the cavity volume of the temperature sensitive element is further reduced, the accurate control of the temperature sensitive element is improved, and a secondary heating element and the temperature sensitive element in the camera device can be further divided according to the actual condition of the camera device.

For example, in the photographing apparatus shown in fig. 9, the front of the housing 1 has an opening or a transparent portion for the lens 42, which causes heat of the external environment, particularly, the heat source to affect the temperature inside the temperature controlled chamber 10. Although the influence may be much smaller than that of the heat generating element of the image pickup apparatus, in order to improve the environmental temperature control effect for the temperature sensitive element, the self-controlled temperature chamber 10 including the internal space of the housing may be further partitioned into the first temperature controlled chamber 11 and separated from the focus adjusting section 42 in the second temperature controlled chamber 12.

Since the second temperature-controlled chamber 12 does not include a heat generating element or includes only a heat source having a lower heat amount than the heat generating element, the thickness of the first partition wall 31 may be equal to or greater than the thickness of the second partition wall 32, according to actual needs.

As shown in fig. 9 and 11, in order to fix electronic components such as a lens, a gun camera, etc. in the housing 1, the image pickup apparatus of the present embodiment further includes a camera holder 5 and a lens block holder 6, wherein the camera holder 5 is fixed in a cavity of the housing 1 and supports the gun camera 2 from the bottom of the gun camera 2, and the lens block holder 6 is fixed to the camera holder 5 and supports the lens block 4 from the bottom of the lens block 4.

Correspondingly, the first partition wall 31 may further comprise a first partition wall second leg 31b, the first partition wall second leg 31b filling a gap between the bottom of the camera support 5 and the housing 1. Likewise, the second partition wall 32 may further include a second partition wall second branch piece 32b, and the second partition wall second branch piece 32b fills a gap between the bottom of the lens assembly holder 6 and the housing 1.

In a preferred embodiment, both sides of the camera support 5 or the lens module support 6 further include first partition wall fixing grooves 511, and the first partition wall first branch pieces 31a may be caught in the first partition wall fixing grooves 511, and likewise, both sides of the lens module support 6 may further include second partition wall fixing grooves 611, and the second partition wall second branch pieces 32b may be caught in the second partition wall fixing grooves 611. Thereby, the inner edge of the first partition wall 31 abuts the outer surface of the gun-shaped camera 2 and/or the camera holder 5, and the inner edge of the second partition wall 32 abuts the outer surface of the lens module 4 and/or the lens module holder 6.

The positions of the first and second partition wall fixing grooves 511 and 611 correspond to the positions of the first and second partition walls 31 and 32, respectively, and in the example shown in fig. 11, the first and second partition wall fixing grooves 511 and 611 are provided on the lens assembly holder 6. The function of the bracket is to provide a quick mounting structure and a fixed support for the first partition wall 31 and the second partition wall 32 by using the existing structure of the fixed bracket.

In the embodiment of the image pickup apparatus shown in fig. 9, since the length of the gun camera and the lens is long, the lens may be fixed to the lens block holder 6 by the lock attaching plate 43.

Fig. 12 is a schematic configuration diagram of a fifth embodiment of the image pickup apparatus of the present invention. As shown in fig. 12, the present embodiment discloses an image pickup apparatus, which is added with a heat dissipation element, namely a temperature adjustment device 50, on the basis of the fourth embodiment, the temperature adjustment device 50 is arranged at a position corresponding to the second temperature control chamber 12 and is used for adjusting the temperature in the second temperature control chamber 12 to be within a predetermined temperature range.

In the present embodiment, the temperature adjustment target of the temperature adjustment device 50 is the second temperature control chamber 12, not the entire casing interior, and not the entire temperature control chamber 10 interior, and the adjustment efficiency of the temperature adjustment device 50 is significantly improved due to the reduction of the spatial volume. Further, due to the existence of the first partition wall 31 and the second partition wall 32, the influence of the use environment temperature of the heating element and the electronic device on the environment temperature in the temperature control chamber 10 is greatly prevented, so that the environment temperature in the second temperature control chamber 12 does not greatly exceed the predetermined temperature range (the normal operating temperature range of the temperature sensitive element), and the work load of the temperature adjusting device 50 is greatly reduced.

In the present embodiment, the temperature adjustment device 50 may have only a temperature reduction function, or both the temperature reduction and temperature increase functions. Correspondingly, the second temperature control chamber 12 further has a temperature sensor therein, and the controller turns on or off the temperature adjustment device 50 according to the measured temperature of the temperature sensor.

When the temperature adjustment device 50 has both the temperature reduction and temperature increase functions, in the image pickup device of the present embodiment, the inner surface of the housing 1 may not need to be additionally provided with an insulating material. When the temperature in the second temperature-controlled cavity 12 is higher than the predetermined temperature range due to the heat emitted from the heating element or the ambient temperature, the controller controls the temperature-adjusting device 50 to start cooling so as to lower the temperature in the second temperature-controlled cavity 12 to be within the predetermined temperature range. Likewise, when the temperature of the second temperature-controlled chamber 12 is lower than the predetermined temperature range due to the ambient temperature, the controller controls the temperature-adjusting device 50 to start the temperature rise to raise the temperature in the second temperature-controlled chamber 12 to be within the predetermined temperature range. And when the temperature in the second temperature control chamber 12 is within the predetermined temperature range, the thermostat 50 may not be activated.

In a preferred embodiment, the temperature adjustment device 50 may be implemented as a semiconductor Cooler (Thermo Electric Cooler), and when a direct current passes through a couple composed of two semiconductor materials, one end absorbs heat and the other end releases heat, so that the temperature of the temperature adjustment device 50 can be controlled to be lowered or raised according to the direction of the current.

Wherein the temperature adjustment device 50 may be arranged in a similar manner to the temperature adjustment device 50 in the second embodiment. Wherein the temperature adjusting device 50 is arranged in the second temperature control chamber 12. The temperature adjustment device 50 includes a first heat dissipation surface 51 and a second heat dissipation surface 52, the heat dissipation tendencies of the first heat dissipation surface 51 and the second heat dissipation surface 52 are opposite, that is, when the first heat dissipation surface 51 absorbs heat, the second heat dissipation surface 52 releases heat, and when the first heat dissipation surface 51 releases heat, the second heat dissipation surface 52 absorbs heat.

Accordingly, the temperature adjustment device 50 is fixed to the housing 1 such that the first heat dissipation surface 51 is disposed in the second temperature control chamber 12 and the second heat dissipation surface 52 is disposed outside the second temperature control chamber 12, and the first heat dissipation surface 51 is controlled to cool or heat the second temperature control chamber 12 by controlling the current direction of the temperature adjustment device 50.

In a preferred embodiment of the temperature adjustment device 50 of the image pickup apparatus of the present invention shown in fig. 5 and 6, it further includes:

a first heat sink 61, the bottom surface of the first heat sink 61 being attached to the first heat dissipation surface 51, the area of the bottom surface of the first heat sink 61 being equal to or larger than the first heat dissipation surface 51;

a second heat sink 62, wherein the bottom surface of the second heat sink 62 is attached to the second heat dissipation surface 52, and the area of the bottom surface of the second heat sink 62 is larger than or equal to that of the second heat dissipation surface 52;

and the heat insulation foam 63, wherein the heat insulation foam 63 surrounds the temperature adjusting device 50 from the periphery and is positioned between the bottom surface of the first radiating fin 61 and the bottom surface of the second radiating fin 62.

In combination with the above, as shown in the structural diagram of the bottom surface of the housing shown in fig. 7a, the housing 1 further includes a heat dissipation opening 1a, and in combination with the structural diagram of the bottom surface of the housing shown in fig. 7b, where the temperature adjustment device 50 is installed, the first heat dissipation surface 51 faces the inside of the cavity of the housing 1, and the second heat dissipation surface 52 faces the outside of the housing 1 and is exposed to the heat dissipation opening 1 a. Accordingly, the second heat sink 62 is fixed to the outside of the housing 1.

Accordingly, the first heat dissipation surface 51 absorbs or radiates heat inside the second temperature control chamber 12 through the first heat dissipation fins 61, and the second heat dissipation surface 52 absorbs or radiates heat outside the case 1 through the second heat dissipation fins 62. The first radiating fin 61 and the second radiating fin 62 are isolated by the heat insulation foam 63, and heat is not mutually transferred.

The first heat dissipation surface 51 and the bottom surface of the first heat dissipation plate 61 may be filled with a thermal interface material, and correspondingly, the second heat dissipation surface 52 and the bottom surface of the second heat dissipation plate 62 may also be filled with a thermal interface material.

In a specific example, the fins of the first cooling fin 61 are distributed at equal intervals, the thickness of the fins is controlled to be 0.5-2mm, the interval between adjacent fins is controlled to be 1-5mm, and the depth of the fins is controlled to be 5-50 mm. The fins of the second radiating fins 62 are distributed at equal intervals, the thickness of the fins is controlled to be 0.5-3mm, the interval between adjacent fins is controlled to be 3-15mm, and the depth of the fins is 20-80 mm. The thickness of the heat insulation foam 63 can be controlled within 2-8 mm.

The overall volume of the first heat sink 61 should be smaller than the volume of the second heat sink 62 due to space constraints inside the image pickup device, and accordingly, the fin pitch, thickness, depth, etc. of the first heat sink 61 may each be smaller than the fin pitch, thickness, depth, etc. of the second heat sink 62.

As shown in fig. 5 and 6, the second heat sink 62 may further include a sealing groove 621 on a bottom surface thereof to receive a sealing ring 622 for sealing contact with the bottom surface of the case 1. Wherein the sealing groove 621 surrounds the thermal insulation foam 63. In the present embodiment, the area of the heat dissipation hole 1a should be smaller than the area of the bottom surface of the second heat dissipation plate 62, but may be larger than or equal to the area of the bottom surface of the first heat dissipation plate 61, and the temperature adjustment device 50 is fixedly connected to the bottom surface of the housing 1 through the screw hole at the end corner of the second heat dissipation plate 62.

In order to further reduce the internal space of the image pickup device occupied by the first heat radiation fins 61 and improve the heat radiation efficiency of the temperature adjustment device 50, the image pickup device of the present embodiment further includes, similarly to the third embodiment of the image pickup device shown in fig. 8:

the vortex fan 70, the air inlet 71 and the air outlet 72 of the vortex fan 70 are perpendicular to each other, the air inlet 71 is adjacent to the first heat sink 61 or the first heat dissipating surface 51, and the air outlet 72 is disposed vertically upward so as to face the side edge of the lens assembly 4. That is, the air outlet 72 and the air inlet 71 are perpendicular to each other.

In a preferred embodiment, the air outlet 72 is adjacent to the inner surface of the housing 1, and the air outlet 72 forms an acute angle with the inner surface of the housing 1 to form an annular air flow within the housing 1.

Different from the conventional axial flow fan, since the air outlet 72 of the vortex fan changes the angle between the air outlet direction and the air inlet direction, so that the air outlet direction forms an acute angle with the inner surface of the housing 1, and the air flow direction discharged from the air outlet 72 forms an obtuse angle with the inner surface of the housing 1, the air flow is not reversely rebounded by the inner surface of the housing 1, but is guided by the inner surface of the housing 1 to flow, so that an annular air flow surrounding the lens assembly 4 as shown by an arrow in fig. 8 is formed along the inner surface of the housing 1, and the annular air flow is more uniformly distributed in the environment where the lens assembly 4 is located, so that the annular air flow can sufficiently surround the temperature-sensitive element, and thus the temperature of the second temperature-controlling cavity 12, particularly the lens assembly 4, is sufficiently and uniformly reduced or increased.

And the fin pitch of the first heat radiation fins 61 can be further reduced, for example, adjusted to 1-5mm, due to the heat radiation function of the eddy fan 70.

The clearance between the air inlet 71 of the fan 70 and the first heat sink 61 is kept within 50 mm; the fins of the first heat sink 61 are directed toward the air inlet 71 of the vortex fan 70; the lens assembly 4 is provided with a clearance for air circulation in the chamber over one revolution of the position of the fan 70, the minimum clearance being approximately 10 mm.

In this embodiment, the heating elements, i.e., the gun camera 2 and the power supply assembly 3, which will cause the temperature inside the casing to rise, and the temperature-sensitive elements, i.e., the lens assemblies, which have a high requirement on the temperature inside the casing are respectively disposed in different cavities, and the cavities are sealed and separated by a heat insulating material, so that the heat emitted by the heating elements is prevented from affecting the temperature inside the whole casing, especially the heat of the heating elements is prevented from affecting the temperature inside the temperature-control cavity, and the influence of the heating elements on the temperature-sensitive elements is eliminated, and even if there is no heat dissipating element, the ambient temperature of the lens assemblies is better than that of the cavities without division.

Further, the present embodiment divides the interior of the housing into cavities, so that the temperature control of the electronic components in the image pickup device can be refined to local control. For example, the heat dissipation element may be disposed in the heat generating cavity to more efficiently reduce the temperature rise caused by the heat generating element, thereby reducing the ambient temperature inside the housing of the image pickup device from the source. Or, the heat dissipation element can be arranged in the temperature control cavity to accurately control the environmental temperature of the lens assembly, and the temperature control cavity in which the lens assembly is located is less affected by the heating element because the lens assembly and the heating element are sealed and separated by the heat insulation material, so that the heat dissipation efficiency of the heat dissipation element to the temperature control cavity is far greater than the heat dissipation efficiency of the whole shell.

The temperature control cavity is further divided into a first temperature control cavity and a second temperature control cavity, so that the volume of the cavity where the temperature sensitive element is located is further reduced, the accurate control of the temperature sensitive element is improved, and a secondary heating element and the temperature sensitive element in the camera device can be further divided according to the actual condition of the camera device.
