In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Fig. 1 is a sectional view showing an assembly structure of a video camera in one embodiment of the present invention. Fig. 2 is an exploded structural sectional view of the video camera shown in fig. 1.

Referring to fig. 2 in conjunction with fig. 1, in an embodiment, a video camera may include a body assembly 1, a cover assembly 2, a movement assembly 3, and a fill-in light assembly 4.

The fuselage assembly 1 may have an open end face 100, for example, the fuselage assembly 1 may include a casing 10, the casing 10 including a rear end plate 11, and a cylindrical wall 12 surrounding a shell cavity on one side (front side) of the rear end plate 11, the front end of the cylindrical wall 12 being open to form the open end face 100 of the fuselage assembly 1.

The cover assembly 2 may cover the open end face 10 of the body assembly 1 to close the housing cavity of the enclosure 10 of the body assembly 1.

The movement assembly 3 and the light supplement assembly 4 may be located inside the body assembly 1, for example, in a housing cavity of the housing 10 of the body assembly 1, and the cover assembly 2 may provide an imaging view for the lens 30 of the movement assembly 3 and an illumination view for the light emitting module 40 of the light supplement assembly 4.

In addition, the camera in this embodiment may further include a control unit 5 for supplying a control signal to the movement unit 3 and the fill-in unit 4, and a power supply unit 6 for supplying power to the movement unit 3, the fill-in unit 4, and the control unit 5 inside the body unit 1 (for example, inside a housing cavity of the housing 10), and the camera may be further provided with a cable unit 7 for supplying external power to the power supply unit 6, supplying a control signal to the control unit 5, and transmitting an image output from the movement unit 3. The control assembly 5 may include a PCB (Printed Circuit Board), and the cable assembly 7 may be mounted to the body assembly 1 (e.g., the rear end plate 11) through a screw structure.

Based on the above structure, the light supplement unit 4 can be built in the body unit 1 together with the movement unit 3, and thus, it is possible to contribute to downsizing of the external size of the video camera.

At this time, in order to avoid the interference of the reflection of the fill-in light beam on the imaging quality, the embodiment provides an optimized solution for the structure of the cover assembly 2.

Fig. 3 is a sectional view showing an assembled structure of a cover assembly of the video camera shown in fig. 1. Fig. 4 is an exploded view of the cap assembly shown in fig. 3.

The press-fitting assembly 23 is configured to press-fit and limit the imaging lens 21a and the lamp group lens 21b to the end cap 20, and the press-fitting assembly 23 has a second imaging window hole 23a aligned with the first imaging window hole 20a and a second light compensation window hole 23b aligned with the first light compensation window hole 20 b. Specifically, the press-fitting assembly 23 may be provided with a plate-like body formed integrally, and the press-fitting assembly 23 has a second imaging window hole 23a fitted in shape to the first imaging window hole 20a and the imaging lens 21a, and a second compensation window hole 23b fitted in shape to the first compensation window hole 20b and the lamp group lens 21b, respectively.

The light-emitting module 40 of the light supplement component 4 is located at the second light supplement window hole 23b, and a light-emitting surface of the light-emitting module 40 faces the lamp set lens 21 b.

The end cap 20 further has a light blocking partition 200 protruding between the first imaging window hole 20a and the first light compensation window hole 20b, the buffer assembly 22 forms a light blocking cylinder wall (cylindrical cylinder wall) 220b along the edge of the second light compensation window hole 23b, and the light compensation assembly 4 is press-fitted with the buffer layer 222 b.

That is, the imaging lens 21a may be fixedly mounted on the end cover 20 at the inner circumferential side of the light blocking partition 200, the lamp group lens 21b may be fixedly mounted on the end cover 20 at the outer circumferential side of the light blocking partition 200, the height of the protrusion of the light blocking partition 200 may be equal to or substantially equal to the thickness of the imaging lens 21a and the lamp group lens 21b, so that the light blocking partition 200 may form a light blocking barrier in the entire thickness space of the imaging lens 21a and the lamp group lens 21b, and the light blocking cylinder wall 220b formed by the buffer component 22 is located at the mirror surface side of the lamp group lens 21b facing the interior of the body component 1, so that the light blocking cylinder wall 220b may form a light blocking barrier at the mirror surface side of the first protective lens 21a and the second protective lens 21b facing the interior of the body component 1.

Fig. 5 is a sectional view of an assembly structure of the cap assembly and the light supplement module shown in fig. 3. Fig. 6 is a schematic view illustrating a principle of reflective shielding of the cover assembly shown in fig. 3 with respect to the fill light assembly shown in fig. 6. Referring to fig. 5 with particular attention paid to fig. 6, an axial length L1 of the light blocking cylinder wall 220b formed by the buffer assembly 22 may be greater than an axial gap L2 between the light supplement assembly 4 and the second light supplement viewing window hole 23b, which are disposed in the same cavity as the movement assembly 3, and the axial gap L2 is a fixed gap formed between the light supplement assembly 4 and the second light supplement viewing window hole 23b after the light supplement assembly 4 is fixedly mounted (e.g., the press-fitting assembly 23 mounted on the cover assembly) in the same cavity as the movement assembly 3.

Based on the above embodiment, the lens 30 of the movement assembly 3 can be located at the second imaging window hole 23a, and the lens 30 faces the imaging lens 21a, the light-emitting module 40 of the light supplement assembly 4 can be located at the second light supplement window hole 23b, and the light-emitting surface of the light-emitting module 40 faces the light set lens 21b, therefore, the cover assembly 2 can provide an imaging field of view for the lens 30 of the deck assembly 3 using the imaging lens 21a exposed in both directions at the first imaging window hole 20a and the second imaging window hole 23a, in addition, the lamp group lens 21b exposed in the first light compensation window hole 20b and the second light compensation window hole 23a in two directions can be used for providing an irradiation field surrounding the imaging field for the light emitting module 40 of the light compensation assembly 4, therefore, the light supplement module 4 can be supported to be built in the body module 1 together with the movement module 3, which contributes to the miniaturization of the external size of the camera.

Further, the light blocking cylinder wall 220b formed by the buffer member 22 is located on the mirror surface side of the lamp group lens 21b facing the interior of the body unit 1.

Fig. 7 is a schematic view of the reflective shielding principle shown in fig. 6 when applied to the camera shown in fig. 1. Referring to fig. 7 and referring back to fig. 6, when the light supplement assembly 4 disposed in the same cavity as the movement assembly 3 is located at the second light supplement viewing window 23b, the light blocking cylinder wall 220b can completely cover the axial gap L2 between the light supplement assembly 4 and the lamp group lens 21b in the axial direction, so that the light beam generated by the light emitting module 40 of the light supplement assembly 4 can be prevented from being reflected by the lamp group lens 21b to the imaging viewing field provided by the imaging lens 21a, and thus, the reflection interference of the light supplement light beam on the imaging quality can be avoided while the external size of the camera is reduced.

In addition, the press-fitting assembly 23 limits the press-fitting of the imaging lens 21a and the lamp group lens 21b, which can improve the assembling strength of the cap assembly 2 and contribute to providing the cap assembly 2 with explosion-proof characteristics.

In order to better understand the above effects, the structure of the cap assembly 2 will be described in further detail below.

Still referring to fig. 3 in conjunction with fig. 4, in this embodiment, the end cap 20 may have a front end plate 201, and a peripheral wall 202 surrounding the side (e.g., back side) of the front end plate 201 that forms a cap cavity.

Here, the first imaging window hole 20a may be used to provide a perspective area for a lens field of view of the engine assembly 3, and thus, the first imaging window hole 20a may be set to a circular shape matching the lens field of view of the engine assembly 3. Accordingly the imaging optics 21a may be circular.

The first light compensation viewing window hole 20b can be used for illumination transmission of the light compensation assembly 4, and therefore, the shape of the first light compensation viewing window hole 20b can be set arbitrarily according to the arrangement of the light emitting module 40 of the light compensation assembly 4.

Further, the first imaging window holes 20a and the first compensation window holes 20b may be adjacently arranged in the plate surface space of the end plate 201, and the area of the first compensation window holes 20b may be smaller than the area of the first imaging window holes 20 a.

Both the imaging lens 21a and the lamp group lens 21b may be accommodated in a cover cavity formed by surrounding the peripheral wall 202, that is, the imaging lens 21a may be accommodated in one sub-cavity on one side of the light blocking partition 200, and the lamp group lens 21b may be accommodated in the other sub-cavity on the other side of the light blocking partition 200.

The thickness t1 of the imaging lens 21a and the thickness t2 of the lamp group lens 21b may be the same, or the thickness t1 of the imaging lens 21a and the thickness t2 of the lamp group lens 21b may be different.

The thickness t1 of the imaging lens 21a and the thickness t2 of the cluster lens 21b may be equal to or slightly greater than the protrusion length h0 of the light blocking partition 200. Also, the thickness t1 of the imaging lens 21a and the thickness t2 of the lamp group lens 21b may both be smaller than the axial length L0 of the peripheral wall 202, so as to allow both the buffer assembly 22 and the press-fitting assembly 23 to be located in the cover cavity, and even further accommodate the fill light assembly 4.

To the condition that there is explosion-proof demand in the camera, rigid metal material such as stainless steel can be chooseed for use to end cover 20, and explosion-proof printing opacity material such as toughened glass can be chooseed for use to formation of image lens 21a and banks lens 21b to, rigid metal material such as stainless steel can be chooseed for use to pressure equipment subassembly 23.

At this time, the thickness t1 of the imaging lens 21a and the thickness t2 of the lamp group lens 21b may be set to satisfy a preset explosion proof level. The explosion-proof grade can be calibrated by the test results of reference pressure test, overpressure test, internal ignition without explosion propagation and the like.

Also, since the peripheral wall 202 may protrude into the housing cavity of the housing 10 of the body assembly 1 and engage with the housing cavity inner wall of the housing 10 in a nested manner, the axial length L0 of the peripheral wall 202 may be set to satisfy a predetermined length, for example, L0 may be set to 25mm or more, to ensure that the engagement area of the cover assembly 2 with the body assembly 1 may satisfy a preset explosion proof level.

In addition, in order to improve the explosion-proof performance, the end cover 20 can also support the cover assembly 2 to be fixedly connected with the machine body assembly 1 by using the assembly connecting piece 8.

Referring back to fig. 3 in conjunction with fig. 1 and 2, the end cap 20 may further have a mounting flange 203, i.e., the end cap 20 may also have a mounting flange rim 203 protruding in a radial direction from the outside of the peripheral wall 202, e.g., the mounting flange rim 203 may protrude in a radial direction from the outside of the peripheral wall 202 at a position aligned with the front end plate 201.

The mounting flange edge 203 of the cover assembly 2 may be fixedly connected with the mounting flange edge 13 of the fuselage assembly 1 for fixedly mounting the cover assembly 2 with the fuselage assembly 1, and the fixed connection between the mounting flange edge 203 of the cover assembly 2 and the mounting flange edge 13 of the fuselage assembly 1 may be designed to meet explosion-proof requirements, for example, the mounting flange edge 203 of the cover assembly 2 is fixedly connected with the mounting flange edge 13 of the fuselage assembly 1 by the assembly connector 8 such as a screw, so as to realize explosion-proof butt-joint mounting of the cover assembly 2 and the fuselage assembly 1. That is, the mounting flange 203 may be provided with a mounting connection 8 for connection to the fuselage assembly 1.

Fig. 8 is a partially enlarged view of a portion a of fig. 3. Referring to fig. 8 in addition to fig. 3, the imaging lens 21a and the lamp lens 21b may be adhered to the end cap 20. For example, the imaging lens 21a and the lamp group lens 21b may be adhesively attached to the end cap 20 by a glue (e.g., an epoxy AB glue) applied to at least one of the front end plate 201, the peripheral wall 202, and the light blocking partition 200 of the end cap 20.

When the imaging lens 21a and the lamp group lens 21b are bonded to the front panel 201, the front panel 201 may have a first dispensing groove 204a disposed around an outer peripheral side of the first imaging viewing window hole 20a and a second dispensing groove 204b disposed around an outer peripheral side of the first compensation viewing window hole 20 b. Thus, the imaging lens 21a can be bonded to the front plate 201 by the glue filled in the first glue dispensing groove 204 a; the lamp unit lens 20b may be bonded to the end plate 201 by the glue filled in the second glue dispensing groove 204 b.

If the imaging lens 21a and the lamp group lens 21b are adhesively attached to the end cap 20, the adhesive may overflow from the first dispensing groove 204a due to being pressed by the imaging lens 21a and/or the adhesive may overflow from the second dispensing groove 204b due to being pressed by the lamp group lens 21 b.

The adhesive force is easily lost due to the overflow of the adhesive, and if the overflow adhesive flows into the window range of the first imaging window hole 20a and/or the first light compensation window hole 20b, the mirror surface contamination of the imaging lens 21a and/or the lamp group lens 21b may be caused.

To avoid this, the front panel 201 may further arrange a first glue overflow groove 205a between the first glue dispensing groove 204a and the edge of the first imaging viewing aperture 20a, and a second glue overflow groove 205b between the second glue dispensing groove 204b and the edge of the first light compensation viewing aperture 20 b. The first glue overflow groove 205a and the second glue overflow groove 205b can absorb the overflowed glue and help the glue to diffuse and distribute on the front plate 201.

When the imaging lens 21a and the lamp group lens 21b are bonded to the light blocking partition 200, a first radial gap for filling the colloid may be reserved between the imaging lens 21a and the light blocking partition 200, and a second radial gap for filling the colloid may be reserved between the lamp group lens 21b and the light blocking partition 200.

When the imaging lens 21a and the lamp group lens 21b are bonded to the peripheral wall 202, a third radial gap for filling the colloid may be reserved between the imaging lens 21a and the peripheral wall 202, and a fourth radial gap for filling the colloid may be reserved between the lamp group lens 21b and the peripheral wall 202.

In the case of a camera requiring explosion protection, the imaging lens 21a and the lamp group lens 21b can be bonded and assembled with the end cap 20 through the glue applied to the front end plate 201, the peripheral wall 202 and the light blocking partition 200 of the end cap 20. Wherein the glue applied by the front end plate 201 extends in the radial direction of the end cap 20, the glue applied by the peripheral wall 202 and the light blocking partition 200 extends in the axial direction of the end cap 20, and the sum of the extension dimension L1 or L1 'of the glue in the radial direction of the end cap 20 and the extension dimension L2 or L2' in the axial direction of the end cap 20 may be greater than a preset bonding dimension threshold, for example, L1+ L2 > 10mm, L1 '+ L2' > 10 mm.

Fig. 9 is a schematic view of the press-fitting assembly of the cap assembly shown in fig. 3. Referring to fig. 9 in conjunction with fig. 3 and 4, the second imaging viewing aperture 23a of the press-fitting assembly 23 may be provided at a position overlapping the first imaging viewing aperture 20a and may have substantially the same shape as the first imaging viewing aperture 20a, and the second imaging viewing aperture 23a of the press-fitting assembly 23 may be provided to have the same size as the first imaging viewing aperture 20a or may be provided to be slightly smaller or slightly larger than the first imaging viewing aperture 20 a. Similarly, the second light compensation viewing window hole 23b of the press-fitting assembly 23 may be provided at a position overlapping the first light compensation viewing window hole 20b and may have substantially the same shape as the first light compensation viewing window hole 20b, and the second light compensation viewing window hole 23b of the press-fitting assembly 23 may be sized to be the same as the first light compensation viewing window hole 20b or may be sized to be slightly smaller or slightly larger than the first light compensation viewing window hole 20 b.

The press-fitting assembly 23 may be secured to a press-fitting assembly mounting block 206 mounted to the end cap 20 by press-fitting assembly fasteners 24 (e.g., screws) to compress the imaging optics 21a and the lamp assembly optics 21 b.

As also clearly shown in fig. 4, the end cap 20 may further have a movement mounting post 207 for mounting the movement assembly 3, so that the movement assembly 3 can be mounted on the end cap 2 (end cap 20), and accordingly, the press-fitting assembly 23 may further have an escape notch 231 escaping from the movement mounting post 207, and the escape notch 231 is distributed around the second imaging window hole 23 a.

As shown in fig. 9, the press-fitting assembly 23 may further have a lamp group mounting post 230 for mounting the supplementary lighting assembly 4, so that the supplementary lighting assembly 4 is mounted on the cover assembly 2 (the press-fitting assembly 23), wherein the lamp group mounting post 230 is distributed around the second supplementary viewing aperture 23 b.

Fig. 10 is a view illustrating an assembled structure of the buffering assembly and the press-fitting assembly of the cap assembly shown in fig. 3. Referring to fig. 10 in conjunction with fig. 3 and 4, the buffer assembly 22 may include a mirror cushion 22a and a lamp mirror cushion 22b, and although the mirror cushion 22a and the lamp mirror cushion 22b are shown as two separate elements, it is understood that the mirror cushion 22a and the lamp mirror cushion 22b may be integrated.

Fig. 11a and 11b are schematic views illustrating the structure of a mirror-like cushion of the cover assembly shown in fig. 3. The mirror cushion 22a may provide a cushioning contact of the press-fitting assembly 23 with the imaging lens 21a, for example, the mirror cushion 22b may have a first mirror washer 221a around the periphery of the edge of the second imaging viewing aperture 23a, the first mirror washer 221a being pressed between the press-fitting assembly 23 and the imaging lens 21 a.

The mirror cushion 22a may further have a structure similar to the light blocking cylinder wall 220b, for example, the mirror cushion 22a may further have a protective cylinder wall 220a, and one end of the protective cylinder wall 220a may contact the imaging lens 21a and be connected to the first mirror cushion 221 a. Thus, even if the light blocking tube wall 220b is damaged due to, for example, aging of the lens cushion 22b, and the like, so that the light generated by the light supplement module 4 cannot be completely shielded and a small amount of light is leaked, the protective tube wall 220a can also play a role of supplementary light shielding for preventing the small amount of leaked light from entering the imaging field of view.

In addition, the mirror cushion 22a has a radially inner recess formed between the first mirror washer 221a and the second mirror washer 222a for holding the outer peripheral edge of the first light compensation window hole 23 a.

Accordingly, the first imaging viewing aperture 20a, the imaging lens 21a, and the second imaging viewing aperture 23a (based on the buffer fit of the mirror cushion 22 a) constitute a first optical path channel for camera imaging. Also, the light supplement component 4 may be sized to avoid the second imaging viewing aperture 23a located in the first optical path.

Fig. 12a and 12b are schematic views illustrating the structure of a cushion pad of a lamp mirror of the cover assembly shown in fig. 3. The lens cushion 22b can be regarded as a light blocking member including a light blocking cylindrical wall (cylindrical wall) 220b and an assembly buffer layer 222 b. That is, the lens cushion (light blocking member) 22b may be formed with a cylindrical wall 220b along the edge of the second light compensation window hole 23b and an assembly buffer layer 222b extending outward from the light blocking wall 220b on the side of the press-fitting member 23 remote from the end cap 20.

Accordingly, the first light compensation viewing window hole 20b, the lamp group lens 20b, the second light compensation viewing window hole 23b, and the lamp mirror cushion (light blocking member) 22b constitute a second light path channel for light compensation of the camera. The size of the light supplement component 4 may be configured to cover the lamp lens cushion (light blocking component) 22b, and the light supplement component 4 may be pressed and fixed with the lamp lens cushion (light blocking component), so that the light supplement light generated by the light emitting module 40 in the second light path channel may be prevented from entering the second light path channel by the lamp lens cushion (light blocking component) after being reflected by the lamp lens 21 b.

Also, the lens cushion (light blocking member) 22b may also provide a cushion contact of the press-fitting member 23 with the lens 21b of the lamp group.

For example, the lens cushion 22b may have a first lens washer 221b around the periphery of the edge of the second light compensation viewing hole 23b, the first lens washer 221b may be pressed between the press-fitting assembly 23 and the lamp group lens 21b as a lens buffer layer, and the first lens washer 221b connects one end of the light blocking cylinder wall 220b contacting the lamp group lens 21 b.

The lens cushion 22b may have a second lens washer 222b surrounding the periphery of the second light compensation window hole 23b to serve as an assembly buffer layer, wherein the second lens washer 222b is attached to the surface of the press-fitting assembly 23 facing away from the lens 21b, and the second lens washer 222b is connected to the other end of the light blocking barrel wall 220b away from the lens 21 b.

Further, the lens cushion (light blocking member) 22b has a radially inner notch formed between the first lens washer (lens cushion) 221b and the second lens washer (fitting cushion) 222b to hold the outer peripheral edge of the second light compensation viewing window hole 23 b.

Fig. 13 is a schematic view illustrating an assembly relationship between the cap assembly and the fill light assembly shown in fig. 3. Referring to fig. 13, the light supplement unit 4 may have a mounting hole for fastening a lamp assembly fastening member 25 (e.g., a screw) to the light source mounting post 230 by using the press-fitting unit 23 protruding from the surface of the light source mounting post 230 facing away from the end cap 20, so that the light supplement unit 4 may be mounted on the cap assembly 2 with the light emitting surface located at the lens internal window 23b, and accordingly, the light supplement unit 4 may form an outer ring mounting flange (annular unit) 430 for press-fitting a buffer layer (second lens washer 222b) at the periphery of the light emitting surface.

Fig. 14 is a sectional view illustrating an assembly structure of the light supplement assembly mounted to the cap assembly shown in fig. 3. Fig. 15 is a perspective view illustrating an assembly structure of the light supplement assembly mounted to the cap assembly shown in fig. 3. Fig. 16 is an exploded perspective view of the light supplement assembly mounted on the cap assembly shown in fig. 3. Fig. 17a and 17b are schematic structural views of a lamp cup holder of the light supplement assembly mounted on the cap assembly shown in fig. 3.

Referring to fig. 13 and further referring to fig. 14, 15, 16, 17a and 17b, the light supplement assembly 4 may include a light emitting module 40, an assembly holder 41, a substrate 42, and a lamp holder 43.

The light emitting module 40 may include a first light emitting module 40a and a second light emitting module 40b, the first light emitting module 40a may include a first light source device 42a and a first light guide lamp cup 45a, and the second light emitting module 40b may include a second light source device 42b and a second light guide lamp cup 45 b.

The first Light source device 42a and the second Light source device 42b may be Light-Emitting Diode (LED) lamp-scale elements, and the first Light source device 42a and the second Light source device 42b may generate Light beams of different wavelength bands. For example, one of the first and second light source devices 42a and 42b may generate visible light (such as white light or warm light), and the other of the first and second light source devices 42a and 42b may generate infrared light.

The first and second light guide lamp cups 45a and 45b may be made of a light transmissive material, and the first and second light guide lamp cups 45a and 45b may be shaped to help the first and second light source devices 42a and 42b to diffuse light. For example, the first and second light guide lamp cups 45a and 45b may be provided in a straw hat shape.

The device bracket 41 may have a mounting plate 411 and a leg 412 bent at an edge of the mounting plate 411, and the leg 412 may provide a supporting force for the light compensating device 4 by being supported between the cover assembly 2 and the mounting plate 411 when the light compensating device 4 is mounted to the cover assembly 2.

The substrate 42 may be mounted on the mounting plate 411 of the assembly bracket 41, and the first and second light source devices 42a and 42b may be integrated on the substrate 42.

The cup holder 43 may be mounted on the substrate 42, wherein the cup holder 43 may be formed in a cover shape (the cup holder 43 may also be regarded as a lamp cover), the cup holder 43 may be made of a light shielding material, and the cup holder 43 has a first lamp hole 43a exposing the first light source device 42a and a second lamp hole 43b exposing the second light source device 42 b.

The outer ring assembly flange 430 of the light supplement component 4 may surround the periphery of the end surface of the lamp cup holder 43, and the end surface of the lamp cup holder 43 may be regarded as a light exit surface of the light supplement component 4.

The first light guiding lamp cup 45a of the first light emitting module 40a can be installed in the first lamp hole 43a, and the second light guiding lamp cup 45b of the second light emitting module 40b can be installed in the second lamp hole 43 b. And, the edge of the first lamp hole 43a and the edge of the second lamp hole 43b of the lamp cup holder 43 both have a clip 44, the first light guide lamp cup 45a can be limited in the first lamp hole 43a by the clip 44, and the second light guide lamp cup 45b can be limited in the second lamp hole 43b by the clip 44.

Fig. 18 is a partial schematic view illustrating the press-fitting assembly of the cap assembly and the fill light assembly shown in fig. 3. Referring to fig. 18, when the light supplement component 4 is mounted on the cover component 2 (the light supplement component 4 can also be considered as a part included in the cover component 2, and a component assembly including the light supplement component 4 and the cover component 2 can be considered as a monitoring component), the outer ring assembly flange 430 formed by the light supplement component 4 on the periphery of the light exit surface of the light emitting module 40 can press the buffer component 22 (mirror cushion or light blocking element 22b) on the assembly buffer layer (second lamp lens washer 222b) formed by the press-fitting component 23 to close the aforementioned second light channel for supplementing light to the camera. The inner diameter of the light blocking cylinder wall (cylindrical cylinder wall) 220b may be smaller than the inner diameter of the outer ring assembly flange (annular assembly) 430 formed on the outer periphery of the light-emitting surface of the light supplement module 4, and the outer diameter of the assembly buffer layer (second lens washer 222b) may be larger than the outer diameter of the outer ring assembly flange (annular assembly) 430 formed on the outer periphery of the light-emitting surface of the light supplement module 4.

The light emitting surface (the end surface of the lamp cup holder 43) of the light emitting module 40 may be more protruded than the outer ring assembly flange 430 (the annular assembly) in the direction toward the cap assembly 2, and the outer ring assembly flange 430 (the annular assembly) may be farther away from the lamp lens 21b than the light emitting surface of the light supplement assembly 4 in the axial direction, that is, the light emitting module (40) is closer to the lamp lens 21b than the outer ring assembly flange (the annular assembly) 430. Moreover, the light emitting surface of the light emitting module 40 can also be inserted into the inner window 23b of the lens and enclosed and surrounded by the light blocking cylinder wall 220 b. Therefore, an optical path channel for completely sealing and shielding the light emitting module 40 can be formed between the light emitting surface of the light supplement component 4 and the lamp group lens 21 b.

Still referring to fig. 10 in conjunction with fig. 11 and 12, the lens 30 of the deck assembly 3 may be disposed at the second imaging window 23a, and the lens 30 may partially protrude into the second imaging window 23 a. Moreover, the movement component 3 can be arranged in the cover component 2 in the body component 1 (arranged in the press-fitting component 23. compared with the installation scheme that the cantilever beam structure is used for realizing the movement component 3 in the body component 1, the movement component 3 is fixedly arranged on the cover component 2, and the phenomena of imaging virtual focus and image blurring can be reduced by reducing vibration.

Similar to the assembly buffer layer (the second lamp lens washer 222b), referring back to fig. 3, 4 and 5, the buffer assembly 22 may further form a protective buffer layer on a side of the press-fitting assembly 23 opposite to the imaging lens 21a for preventing the lens 30 of the movement assembly 3 from colliding with the press-fitting assembly 23, and the protective buffer layer may be provided by the image lens buffer 22 a. For example, the lens cushion 22a may further have a second lens washer 222a surrounding the periphery of the second imaging window hole 23a, wherein the second lens washer 222a is attached to the surface of the press-fitting assembly 23 facing away from the imaging lens 21a, and the second lens washer 222a connects the other end of the protective cylinder wall 220a away from the imaging lens 21 a.

In addition, the control assembly 5 may also be mounted to the cover assembly 2 (e.g., the press-fitting assembly 23).

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
