When the observed object is close to the object side end of the second lens 11b (i.e., the object side end of the lens 11 farthest from the lens 11 of the photosensitive assembly 10 in the plurality of lenses 11), the incident light emitted by the light source assembly 12 can be irradiated to the observed object, so as to improve the brightness of the observed object, and thus improve the visibility of observation and shooting.

Among them, in the first lens 11a and the second lens 11b, only one lens may be an enlargement lens having an enlargement function, for example, the first lens 11a may be a normal lens having no enlargement function, and the second lens 11b may be an enlargement lens having an enlargement function. Or, the first lens 11a and the second lens 11b are both magnifying lenses having a magnifying function, so that the magnification of the macro camera module 100 can be obtained by multiplying the magnifications of the first lens 11a and the second lens 11b, so as to improve the magnification of the macro camera module 100, and thus, the macro camera module 100 can be provided with high resolution and low distortion, so that the macro camera module 100 can have excellent optical performance, the magnifying effect is improved, and further, an observed object can be clearly displayed after being magnified, thereby facilitating observation and shooting of a user on a tiny object.

In the embodiment shown in fig. 7 and 8, the light guide member 13 includes a first mounting portion 13a and a second mounting portion 13b, the second mounting portion 13b is provided on the first mounting portion 13a, the second mounting portion 13b is substantially cylindrical, the first mounting portion 13a is substantially rectangular parallelepiped cylindrical, and the outer diameter of the second mounting portion 13b is smaller than the outer diameter of the first mounting portion 13 a. The mounting cavity 132 includes a first portion and a second portion, the first portion is disposed on the first mounting portion 13a and has a first opening 1321, the second portion is disposed on the second mounting portion 13b and has a second opening 1322, the first mounting portion 13a has a light entrance surface 1323, and the second mounting portion 13b has a light exit surface 1324. The light guide 13 includes a first mounting portion 13a and a second mounting portion 13b having different outer diameters, which is beneficial for the incident light received by the light inlet surface 1323 incompletely overlapped with the light outlet surface 1324 to be reflected to the light outlet surface 1324 through the reflection structure 133 and to be transmitted out of the mounting cavity 132, when the observed object is close to the object side end of the lens farthest from the photosensitive assembly 10 in the plurality of lenses 11, the light transmitted from the light outlet surface 1324 of the light guide 13 can make the observed object brighter, thereby improving the clarity of observation and shooting, and facilitating the observation and shooting of a user.

It should be noted that, in practical application, the arrangement of each participating object (such as the observed object, the light source assembly 12, the lens 11, the user, etc.) needs to be considered, so as to avoid interference when each participating object is arranged, and therefore the light entrance surface 1323 cannot be completely overlapped with the light exit surface 1324. Therefore, in the present embodiment, the light entering surface 1323 is deviated from the light exiting surface 1324 by defining the plane perpendicular to the axis L of the mounting cavity 132, so as to avoid interference between the participating objects of the light guide 13 in practical application, and ensure that the light guide 13 can be used normally.

Specifically, the light guide 13 may include a first surface 1325 and a second surface 1326 that are oppositely disposed, the first surface 1325 has the light entering surface 1323, the second surface 1326 has the light exiting surface 1324, the mounting cavity 132 penetrates the first surface 1325 and the second surface 1326, the first opening 1321 is located on the first surface 1325, and the second opening 1322 is located on the second surface 1326. It is understood that the first surface 1325 of the light guide 13 can face the photosensitive component 10 and the second surface 1326 of the light guide 13 can face the observed object in practical application.

Further, it is considered that the light guide 13 cannot simply directly transmit the incident light received by the light entrance surface 1323 to the light exit surface 1324, for example, transmit the light along a straight line, because of the position relationship between the light entrance surface 1323 and the light exit surface 1324. Therefore, in the present embodiment, the light guiding path of the light guiding member 13 is designed, and the reflection structure 133 is used to perform vertical conduction and horizontal conduction on the incident light entering the light inlet surface 1323 substantially vertically, and then the incident light reaches the light outlet surface 1324, where the horizontal conduction is mainly performed to compensate the deviation positions of the light inlet surface 1323 and the light outlet surface 1324, so that the incident light can smoothly reach the light outlet surface 1324 and pass through the installation cavity 132, and thus the observed object can be brighter, the observation and shooting clarity can be improved, and the observation and shooting can be facilitated for the user.

In some embodiments, as shown in fig. 8 and fig. 9, the reflective structure 133 includes a plurality of reflective surfaces 1331, for example, two reflective surfaces 1331, three reflective surfaces 1331, four reflective surfaces 1331, or more reflective surfaces 1331, each of the reflective surfaces 1331 is disposed obliquely to the axis L of the mounting cavity 132, and the incident 5 light received by the light entrance surface 1323 is reflected and transmitted to the light exit surface 1324 through the plurality of reflective surfaces 1331 in sequence. That is, the incident light emitted from the light source module 12 is transmitted from the light entrance surface 1323 to the light exit surface 1324 by the plurality of reflection surfaces 1331, thereby forming a light guide path of the light guide 13. In which fig. 8 shows the light guide path of the light guide 13 (the path shown by the dotted arrow in fig. 8), and the dotted surface represents the surface located inside the light guide 13. Fig. 8 is a schematic optical path diagram, which focuses on showing the light entering surface 1323, the reflecting surface 1331 and the light exiting surface 1324 of the light guide 13, which are related to the light guide optical path, and shows the conducting path of the light guide optical path in the form of an arrow.

This facilitates the incident light emitted from the light source assembly 12 to be reflected to the observed object, so as to improve the brightness of the observed object, and facilitate microscopic observation and shooting.

In some embodiments, the outer surface of the light guide 13 may be a pattern-shining surface, that is, the outer wall surface of the installation cavity 132 of the light guide 13 may be a pattern-shining surface, since the light-emitting surface 1324 belongs to a part of the outer surface of the light guide 13, the light-emitting surface 1324 may be a pattern-shining surface, that is, the light-emitting surface 1324 of the light guide 13 may be subjected to pattern-shining treatment to form pattern-shining grains on the light-emitting surface 1324, and since the light-emitting surface 1324 has the pattern-shining grains, when the incident light emitted by the light source assembly 12 enters from the light-entering surface 1323 and is reflected to the light-emitting surface 1324 by the plurality of reflection surfaces 1331, since the light-emitting surface 1324 has a corresponding uneven shape, the incident light is diffusely reflected and is diffused and irradiated onto the object to be observed, so that the light-emitting surface 1324 can be more uniform, and the brightness of the object to be observed can be substantially maintained uniform, the microscopic observation and shooting are facilitated, and the observation and shooting effects are improved; meanwhile, the effect of weakening surface scraping can be achieved to a certain extent. In addition, by providing the outer surface of the light guide 13 as a bas-textured surface, it is also possible to shield the internal structure of the light guide 13 (for example, the plurality of lenses 11 provided in the mounting cavity 132 of the light guide 13).

Further, the inner wall surface of the installation cavity 132 of the light guide 13 may be coated with a coating (not shown) having a color similar to or the same as the color of the incident light, for example, the incident light emitted by the light source assembly 12 is white, i.e., when the light source assembly 12 emits white light, the coating is white. Through coating the inner wall surface of the mounting cavity 132 with a coating layer with the same or similar color as the incident light, when the light irradiates the coating layer, the light does not enter the plurality of lenses 11 through the coating layer, but is reflected and generates diffuse reflection, so that the light reflection is more uniform, the light emitting of the light emitting surface 1324 is more uniform, the brightness of the observed object can be approximately kept consistent, microscopic observation and shooting are facilitated, and the observation and shooting effects are improved; and also serves to shield the internal structure of the light guide 13.

The macro camera module 100 can be installed on the back 201 of the terminal housing 20, so that the situation that the screen occupation ratio of the intelligent terminal is possibly reduced due to the fact that the macro camera module 100 is installed on the front of the terminal housing 20 can be avoided. And in order not to affect the photographing function of the intelligent terminal, the terminal housing 20 is further provided with a camera 202 without a magnifying function.

In some embodiments, the smart terminal may further include a clamping bracket 21, the clamping bracket 21 is configured to be detachably connected to the terminal housing 20, and when the clamping bracket 21 is connected to the terminal housing 20, a clamping space 210 for disposing the flat observed object 300 is formed between the clamping bracket 21 and the macro camera module 100. Thus, the flat observed object 300 can be arranged by using the clamping space 210, the phenomenon that the flat observed object 300 deviates from the optical path observation position and even falls off from the clamping space 210 due to the fact that the intelligent terminal is moved, shaken or inclined in the amplification observation process is avoided, and the problem that the flat observed object 300 cannot be clearly observed due to the fact that the intelligent terminal is moved, shaken or inclined is solved, namely, even if the intelligent terminal is moved, shaken or inclined in the amplification observation process, the flat observed object 300 can still be clearly observed.

Where reference in this application to flat is to be understood as a structure having a thickness which is much smaller than the length and/or width, such as a sheet-like structure; the flat observed object 300 mentioned in the present application may be understood as a specimen smear (a specimen smear of a bee wing, a specimen smear of a mosquito mouth, a specimen smear transected to arteriovenous of a human body, etc.), a specimen smear (e.g., a human blood permanent smear, a bacterial subtype smear, etc.), or a specimen slice (a permanent cross-section of a soybean stem or a corn stem), etc.

Further, in order to facilitate observation, the user can quickly enter a mode of identifying and observing the flat observed object 300, so as to reduce the operation of the user, and based on the characteristics of no electric shock, low energy consumption, long service life, fast response frequency and the like of the hall switch, a hall switch (not shown) is arranged in the terminal housing 20, and a magnet is arranged at a position of the clamping support 21 corresponding to the hall switch, and the magnet is used for being connected with or disconnected from the hall switch, so that the hall switch controls the start or the stop of the identification software on the terminal housing 20. For example, when the clamping bracket 21 is assembled to the terminal housing 20, the magnet can be quickly turned on by the hall switch to quickly turn on the identification software on the smart terminal, so as to identify and interpret the specimen on the flat observed object 300, help the user to more comprehensively understand and recognize the observed specimen, and facilitate the operation.

In some embodiments, in order to achieve the detachable connection of the clamping bracket 21 to the terminal housing 20, a first magnetic member 22 may be disposed inside the terminal housing 20, and a second magnetic member 211 may be disposed in the clamping bracket 21 at a position corresponding to the first magnetic member 22, wherein the second magnetic member 211 and the first magnetic member 22 are in mutual attraction connection to achieve the detachable connection of the clamping bracket 21 and the terminal housing 20. It will be appreciated that in other embodiments, the clamping module may also be snap-fit or threaded onto the terminal housing 20.

At least one of the first magnetic member 22 and the second magnetic member 211 is a magnet, that is, when the first magnetic member 22 is a magnet, the second magnetic member 211 may be a magnet or a metal member. When the first magnetic member 22 is a metal member, the second magnetic member 211 may be only a magnet.

In some embodiments, as shown in fig. 14 to 17, the outer surface of the terminal housing 20 is provided with a decoration 23 at a position corresponding to the periphery of the macro camera module 100, and the holding bracket 21 is provided with a groove 212 at a position corresponding to the decoration 23, wherein the groove 212 is engaged with the decoration 23. The clamping support 21 is through setting up the recess 212, when installing clamping support 21 to terminal housing 20, can utilize the cooperation of recess 212 and decoration 23 to play the positioning action, so, after installing clamping support 21 to terminal housing 20 installation, the observation window 216 alright aim at the camera lens setting of microspur camera module 100 of clamping module, and need not to adjust the position of clamping support 21 relative terminal housing 20 again, can one step put in place, the installation is high-efficient. Meanwhile, the original decorative part 23 of the macro camera module 100 is matched with the groove 212 of the clamping support 21, so that a flange does not need to be additionally arranged on the back surface 201 of the terminal shell 20, and the original appearance effect of the back surface 201 of the terminal shell 20 can be kept.

For convenience of description, a direction perpendicular to the optical axis of the lens is defined as a lateral direction, for example, a left-right direction in fig. 14. As shown in fig. 14 and 15, a receiving groove 213 extending in the transverse direction is formed, the receiving groove 213 has a vertical opening 214 facing the terminal housing 20 and at least one transverse opening 215 penetrating the holding bracket 21 in the transverse direction, when the holding bracket 21 is connected to the terminal housing 20, a holding space 210 for disposing the flat observed object 300 is formed between the bottom surface of the receiving groove 213 and the macro camera module 100, and the flat observed object 300 can be inserted into the holding space 210 through the transverse opening 215. When the holding bracket 21 is connected to the terminal housing 20, a holding space 210 for disposing the flat observed object 300 is formed between the bottom surface of the receiving groove 213 (i.e., the surface of the receiving groove 213 facing the terminal housing 20) and the macro camera module 100, and the flat observed object 300 can be inserted into the holding space 210 through the transverse opening 215, which is convenient for operation.

For example, the receiving groove 213 may have two lateral openings 215 that are connected in a lateral direction. When the flat observed object 300 is inserted into the holding space 210, two ends of the flat observed object 300 can extend out of the holding space 210 through the corresponding openings, so that an operator can conveniently move the flat observed object 300 in the transverse direction by holding the end of the flat observed object 300 by hand, and replace the observation position of the flat observed object 300, so that the real object on the flat observed object 300 is aligned with the lens, and the operation mode is convenient.

In some embodiments, the bottom surface of the receiving groove 213 is provided with a through observation window 216, and when the holding bracket 21 is connected to the terminal housing 20, the observation window 216 is disposed corresponding to the lens of the macro camera module 100, so that a user can conveniently observe whether the sample on the flat observed object 300 is aligned with the lens, thereby facilitating focusing; meanwhile, external light can be irradiated to the flat observed object 300 through the observation window 216, so as to supplement light.

It can be understood that, in other implementations, the observation window 216 may not be disposed on the bottom surface of the receiving groove 213, so that the color of the flat observed object 300 does not change due to the color change of the external ambient light, which is observed by the macro camera module 100, thereby facilitating the improvement of the identification accuracy of the identification software and the identification of the flat observed object 300 by the identification software; meanwhile, the background of the flat observed object 300 can be kept consistent, so that the display effect of the intelligent terminal is clearer.

In some embodiments, the edge of the transverse opening 215 is provided with a chamfer 2151, that is, the edge of the transverse opening 215 is chamfered (C angle) or rounded (R angle) to avoid scraping the flat observed object 300 by forming a sharp angle at the edge of the transverse opening 215, and at the same time, the edge can play a role of guiding when the flat observed object 300 is inserted, so that a user can better insert the flat observed object.

In some embodiments, the vertical opening 214 is provided with a first limiting inclined surface 2141 extending toward the direction close to the terminal housing 20 and inclining outward, the macro camera module 100 further includes a limiting member 17, the limiting member 17 is provided with a second limiting inclined surface 171 matching with the first limiting inclined surface 2141, when the macro camera module 100 abuts against the vertical opening 214, the second limiting inclined surface 171 abuts against the first limiting inclined surface 2141 to limit the position of the macro camera module 100 extending into the receiving groove 213, that is, during assembly, the first limiting inclined surface 2141 of the holding frame 21 abuts against the second limiting inclined surface 171 of the macro camera module 100, so as to limit the holding frame 21 from moving relative to the macro camera module 100 along the direction toward the macro camera module 100, so as to avoid the thickness of the macro camera module 100 extending into the receiving groove 213 from being too large, which results in a smaller range of the height of the holding space 210, so that it can be ensured that the holding space 210 can be loaded with substantially the flat viewer 300 of a normal full thickness.

Especially, when the clamping bracket 21 is detachably connected to the terminal housing 20 by a magnetic attraction manner, once the clamping bracket 21 is close to the macro camera module 100, which is beneficial to the mutual attraction between the first magnetic component 22 and the second magnetic component 211, the clamping bracket 21 can be magnetically attracted to the terminal housing 20, and due to the existence of the first limiting inclined surface 2141 and the second limiting inclined surface 171, the macro camera module 100 is prevented from excessively extending into the receiving groove 213, so that the clamping space 210 can be ensured to substantially contain the flat observed object 300 with all conventional thicknesses.
