The embodiment of the utility model discloses outer hanging microscope, it can be applied to intelligent terminal for enlarge and observe or shoot, intelligent terminal includes terminal housing and camera, the microscope can include magnifying glass module and clamping module. The magnifying lens module can be configured to be detachably fixed on the terminal shell, when the magnifying lens module is fixed on the terminal shell, the camera is used for collecting light signals passing through the magnifying lens module, and the clamping module is configured to be detachably connected with the magnifying lens module and/or the terminal shell and enables a clamping space used for setting a flat observed object to be formed between the clamping module and the magnifying lens module.
By the design, the flat observed object can be arranged by utilizing the clamping space, the phenomenon that the flat observed object deviates from the optical path observation position and even falls off from the clamping space due to the fact that the intelligent terminal is moved, shaken or inclined in the amplification observation process can be avoided, the problem that the flat observed object 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 can still be clearly observed.
It can be understood that the clamping space formed between the magnifier module and the clamping module for arranging the flat observed object refers to: the clamping space formed between the magnifier module and the clamping module can be used for placing or clamping a flat observed object. Especially, when the clamping space formed between the magnifier module and the clamping module can clamp the flat observed object, in the magnifying observation process, a user can hold the terminal shell to observe the flat observed object, although the flat observed object can be suspended, the clamping space can clamp the flat observed object, and the flat observed object can not fall off from the clamping space, that is, in the magnifying observation process, the intelligent terminal does not need to be placed on a placing plane (such as a desktop, a table top and the like) to support the flat observed object by using the placing plane, so that the flat observed object and the intelligent terminal are kept relatively static, and the use is more convenient.
The magnifier module can be an optical device for observing the tiny details of an object, and the "magnifying imaging" can refer to: the flat observed object can be magnified by the magnifying lens module at a high magnification, for example, a magnified image which can be obtained after being magnified by 10 to 60 times and can be directly observed by eyes.
Reference herein to flat may be understood to refer to structures having a thickness much less than the length and/or width, such as sheet-like structures; the flat observed object mentioned in the present application may be understood as a glass slide, a specimen slide, or a slide attached with an object for microscopic observation (observed object), wherein the specimen slide may include a glass slide, a cover glass, and an object (i.e., an observed object, such as an animal and plant specimen, a human tissue cell specimen, or blood) loaded between the glass slide and the cover glass for magnified observation. For example, when the flat object to be observed is a specimen, it may be a specimen mounted on a wing of a bee, a mosquito mouth, a specimen mounted on a transverse artery and vein of a human body, or the like. It is understood that the flat observed object can also be a specimen smear (such as a human blood permanent smear, a bacterial three-type smear, etc.) or a specimen slice (a permanent cross-section of a soybean stem or a corn stem), etc.
In actual assembling process, the clamping module can be used for being matched with the magnifier module to form a microscope, and the magnifier module of the microscope is installed on the terminal shell of the intelligent terminal, so that the object to be observed can be observed in a magnifying mode or a flat mode can be shot. Of course, the magnifying lens module may be installed on the terminal housing of the smart terminal, and then the clamping module may be fixed on the magnifying lens module and/or the terminal housing of the smart terminal.
The intelligent terminal in the application can be an electronic device capable of improving learning efficiency, and has the functions of specially assisting the subject teaching (electronic textbook, textbook knowledge point interpretation and post-school exercises) of child learning, learning diagnosis (post-school exercise answers and conventional answers), intelligent answering (answering according to student answering thoughts), famous teacher answering (playing knowledge point videos recorded by teachers and talking with teachers through screen to solve teachers in real time), and the like, for example, a tablet computer, a home teaching machine or a mobile phone, and the like. For example, when the microscope is applied to a tablet computer, the magnifier module is mounted on the tablet computer, and particularly detachably mounted at a position corresponding to the camera of the tablet computer, and is disposed corresponding to the camera of the tablet computer, so that when the microscope is mounted on the tablet computer and the flat observed object is inserted into the clamping space, the flat observed object, and particularly, the microstructure of microorganisms, cells or some substances, can be observed.
In one of the application scenarios, for example, when the microscope is applied to a tablet personal computer for children, most users are children, for example, children of 2 to 8 years old, the clamping space of the microscope in the application can clamp the flat observed object, and the magnifier module can be tightly attached to the flat observed object to obtain clear magnified imaging when the flat observed object is inserted into the clamping space, so that the magnifier module is convenient and simple to operate and use, and can well meet the requirements of popular science use of children.
It can be known that children are generally all better, during the use, probably can often remove the panel computer, and by the aforesaid can know, the thing can be by the centre gripping of centre gripping space 300 centre gripping is observed to the platykurtic, can remove along with the panel computer, and remove the in-process, can not influence the degree of hugging closely of thing and magnifying glass module is observed to the platykurtic, consequently even child has removed the panel computer and can not lead to the condition that the microscope appears virtual burnt yet, can strengthen the observability of the microscope in this application like this greatly, it is also easier to go on children's early educational education, the smooth of the educational education of microscope has been guaranteed.
Moreover, the microscope in the application is used for the child tablet personal computer, the amplified image can be displayed on the display screen of the child tablet personal computer, so that observation can be facilitated, the flat specimen to be observed can be explained by means of the child tablet personal computer, and the child can be helped to know and know the observed specimen more comprehensively.
The following will explain in detail about a specific structure of the microscope and a specific connection manner of the microscope to the intelligent terminal.
Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a tablet personal computer as an intelligent terminal according to an embodiment of the present invention. Intelligent terminal 100 includes terminal casing 1, camera 11 and microscope 200, and terminal casing 1 is equipped with shoots the window (not mark), camera 11 locates in terminal casing 1 and frames through shooting the window, and magnifying glass module 2 is configured as can dismantle fixed connection in terminal casing 1, and when magnifying glass module 2 fixed connection was in terminal casing, camera 11 butt was used for gathering the light signal through magnifying glass module 2 in magnifying glass module and to be used for to the collection to camera 11 can acquire the warp the image that magnifying glass module 2 was enlargied, and then lets the user can observe the not directly resolvable mesostructure of naked eye through intelligent terminal 100. The grip module 3 is configured to be detachably attached to the magnifier module 2 and/or the terminal housing 1 and to form a grip space with the magnifier module 2 for placing the flat viewed object 4.
Wherein, camera 11 is used for gathering the light signal through magnifying glass module 2 can understand: when the magnifier module 2 is fixed to the terminal housing 1, the light path passing through the magnifier module 2 can enter the camera 11, so that the camera 11 can acquire the image magnified by the magnifier module 2. Illustratively, the optical axis direction of the magnifier module 2 may coincide with the optical axis direction of the camera 11. The optical axis direction of the magnifier module 2 is the direction indicated by the arrow x in fig. 1.
It can be understood that the intelligent terminal 100 further includes a display screen and components of a main board, a battery, a speaker, a microphone, and a communication module, the display screen is disposed on the front side of the terminal housing 1, and the camera 11 may be a front camera disposed on the front side of the terminal housing 1 or a rear camera disposed on the back side 10 of the terminal housing 1. And the intelligent terminal 100 may further include an application icon used in cooperation with the magnifier module 2, for example, when the magnifier module 2 is installed to the terminal housing 1, when the application icon is opened, the display screen may present an enlarged image in which the camera 11 is framed by the magnifier module 2.
Illustratively, the camera 11 is a rear camera, and the magnifier module 2 is mounted on the rear surface 10 of the terminal housing 1, so as to avoid the situation that the microscope 200 is mounted on the front surface of the terminal housing 1 and may block the display screen. The magnifier module 2 of the microscope 200 may be in the form of a strip or block, and similarly, the clamping module 3 of the microscope 200 may be in the form of a strip or block.
The clamping space of this application can be suitable for the adjustment with the flat observed object 4 of different thickness of adaptation according to the thickness of flat observed object 4, promptly, when inserting the flat observed object 4 of different thickness to clamping space, the flat observed object 4 homoenergetic keeps hugging closely the state with magnifying glass module 2.
In order to enable the clamping space to be adapted to be inserted into the flat observed objects 4 with different thicknesses, and the flat observed objects 4 with different thicknesses can be tightly attached to the magnifying lens module 2 when being inserted into the clamping space, as shown in fig. 3, fig. 3 shows that the clamping module 3 is connected to the terminal housing 1 and can be movable relative to the magnifying lens module 2. As an alternative embodiment, the clamping space 300 may be configured to be adjustable in elevation relative to the magnifier module 2, such that the height h of the clamping space 300 is adapted to accommodate insertion of flat observables 4 of different thicknesses. That is, the holding space 300 may be configured to be movable relative to the magnifier module 2 along the optical axis direction of the magnifier module 2 to adjust the height h of the holding space 300, which is the height of the holding space 300 in the optical axis direction of the magnifier module 2, such that the height h of the holding space 300 fits into flat objects 4 of different thicknesses.
By adopting the design, under the condition of observing the flat observed object 4, the flat observed object 4 with different thicknesses can be replaced without detaching any one part of the magnifier module 2 and the clamping module 3, so that the operation is convenient; and just because the height h of the clamping space 300 can be adjusted according to the thickness of the flat observed object 4, the flat observed object 4 with different thicknesses can be clamped, the flat observed object 4 with different thicknesses can be tightly attached to the magnifier module 2, so that when observing the flat observed object 4 with different thicknesses, the magnifier module 2 can be focused accurately, the focal length of the magnifier module 2 is maintained to be optimized, clear magnified imaging can be presented on the display screen of the intelligent terminal 100, the flat observed object 4 can be observed clearly, that is, after the flat observed object 4 with different thicknesses is replaced each time, the magnifier module 2 does not need to be focused again, the flat observed object 4 can still be observed clearly, and the operation is more convenient.
Illustratively, the microscope 200 further includes a deformation component 31a, such as a silica gel column, a rubber column, a foam column or a spring, which has an elastic deformation capability, the deformation component 31a can be connected to the clamping module 3 and the terminal housing 1, when the flat observed object 4 is inserted into the clamping space 300, the flat observed object 4 will press the clamping module 3, so that the deformation component 31a is elastically deformed, the clamping module 3 moves relative to the magnifier module 2, so as to adjust the height of the clamping space 300, and adapt to the flat observed objects 4 with different thicknesses, and meanwhile, the deformation component 31a will be elastically deformed under the action of the clamping module 3, in this process, the acting force generated by the deformation component 31a can make the clamping module 3 press the flat observed object 4 towards the magnifier module 2, and make the flat observed object 4 tightly adhere to the magnifier module 2, to obtain a sharp magnified image.
The height h of the holding space 300 may be 0.9mm to 1.85mm, for example, 0.9mm, 1.0mm, 1.2mm, 1.3mm, 1.5mm, 1.7mm, 1.8mm, 1.85mm, or the like, based on the thickness of the flat observed object 4 which is usually used.
As another alternative, as shown in fig. 4, fig. 4 shows that the grip module 3 is provided with a hold down and the height of the grip space between the grip module and the magnifier module remains fixed. The microscope 200 further includes a pressing member 31, and the pressing member 31 may be configured to apply a force to the flat observed object 4 inserted into the clamping space 300 in a first direction (opposite to or the same as the optical axis direction of the magnifying lens module 2) to make the flat observed object 4 tightly contact with the magnifying lens module 2, so that the clamping space 300 can be adapted to be inserted into flat observed objects 4 with different thicknesses. That is, when the flat observed object 4 is inserted into the holding space 300, the pressing piece 31 is pressed by the flat observed object to deform, so that the height of the holding space 300 can be adapted to the flat observed object 4 with different thicknesses. Meanwhile, in the process, the flat observed object 4 can be pressed towards the magnifier module 2 by the acting force generated when the pressing piece 31 is pressed by the flat observed object, and the flat observed object 4 is tightly attached to the magnifier module 2, so that the flat observed object 4 can be kept at the observation position of the optimal optical path/preset optical path of the magnifier module 2 to obtain a clear magnified image, and the phenomenon that the flat observed object deviates from the observation position of the optical path or even falls off from the clamping space 300 due to movement, shaking or inclination of the intelligent terminal 100 in the magnifying observation process can be further avoided. In other words, in this embodiment, the height h of the clamping space 300 can be kept fixed due to the pressing piece 31.
It is understood that the pressing member 31 may be a thimble structure, a spring structure, an elastic member structure, or the like. The pressing member 31 may be one or more. When the number of the pressing pieces 31 is one, the pressing pieces 31 may be disposed on any one of the clamping module 3, the magnifier module 2, and the terminal housing 1; when a plurality of pressing members 31 are provided, at least one of the clamping module 3, the magnifier module 2, and the terminal housing 1 may be provided with the pressing member 31, for example, the plurality of pressing members 31 are all provided on the clamping module 3, the magnifier module 2, and the terminal housing 1; for another example, two of the three components of the clamping module 3, the magnifying lens module 2 and the terminal housing 1 are provided with the pressing member 31, and for another example, the clamping module 3, the magnifying lens module 2 and the terminal housing 1 are all provided with the pressing member 31.
The height of the holding space 300 may be 1.85mm based on the thickness of the flat observed object 4, which is usually 0.9mm to 1.85 mm.
In some embodiments, the weight of the magnifier module 2 can be 5g to 7.2g, e.g., 5g, 5.4g, 5.6g, 6.0g, 6.2g, 6.5g, 6.8g, or 7.2g, etc., and the weight of the clamping module 3 can be 6g to 8.8g, e.g., 6g, 6.4g, 6.6g, 6.0g, 7.2g, 7.5g, 7.8g, 8.2g, 8.4g, or 8.8g, etc. Therefore, the quality of the magnifier module 2 and the quality of the clamping module 3 are light, the magnifier module is convenient to carry, and when assembling, the magnifier module 2 and the clamping module 3 are not required to be clamped up by other clamping auxiliary devices, the magnifier module 2 and the clamping module 3 are convenient to assemble, and when assembling the magnifier module 2 and the clamping module 3 to the terminal shell 1, the whole quality of the assembled intelligent terminal 100 is light, and the light-weight design of the intelligent terminal 100 is facilitated.
It can be understood that, when the object of use of the magnifier module 2, the clamping module 3, and the intelligent terminal 100 is a child, the magnifier module 2, the clamping module 3, and the assembled intelligent terminal 100 are all lighter in overall mass, which is convenient for the child to use, for example, hold by hand to pick up and move. Moreover, in use, for convenience, the intelligent terminal 100 is usually supported by a support so as to be capable of standing on a placement plane (such as a desktop or a table) at an angle, so as to facilitate viewing of a display screen of the intelligent terminal. When the intelligent terminal 100 is supported and vertically placed on the placing plane through the support, the weight of the magnifier module 2 and the weight of the clamping module 3 are lighter, on one hand, the magnifier module 2 is not easy to fall off from the intelligent terminal 100, and the clamping module 3 is not easy to fall off from the magnifier module 2 or the intelligent terminal 100; on the other hand, the situation that the intelligent terminal 100 is toppled due to the fact that the weight of the magnifier module 2 and the weight of the clamping module 3 are too heavy can be avoided.
In some embodiments, as shown in fig. 9, the width of the clamping module 3 is D1, 20mm ≦ D1 ≦ 40mm, such as D1 ≦ 20mm, D1 ≦ 24mm, D1 ≦ 28mm, D1 ≦ 32mm, D1 ≦ 36mm, or D1 ≦ 40 mm; the length of the clamping module 3 is L1, L1 is 40mm 70mm, for example, L1 is 40mm, L1 is 44mm, L1 is 48mm, L1 is 52mm, L1 is 66mm, or L1 is 70 mm. The magnifier module 2 has a width D, D ═ D, e.g., D ═ D, or D ═ D, and the like, and a length L, L ═ L, e.g., L ═ L, or L ═ L, and the like. Therefore, the magnifying lens module 2 and the clamping module 3 are small and convenient to carry, and after the magnifying lens module 2 and the clamping module 3 are assembled to the terminal shell 1, the whole size of the intelligent terminal 100 is small after assembly, and the miniaturization design of the intelligent terminal 100 is facilitated.

The lens assembly 23 may include a lens barrel and one or more magnifying lenses disposed in the lens barrel. When the lens assembly 23 includes a plurality of magnifying lenses, the plurality of magnifying lenses may be lenses of different magnifications, so that the flat observed object 4 can be observed at different magnifications.
The optical path direction of the lens assembly 23 from the object side end to the image side end is a first direction, such as the direction indicated by the upward arrow in fig. 5.
In some embodiments, as shown in fig. 6 to 8, a receiving groove is formed between the holding module 3 and/or the magnifying lens module 2, the receiving groove extends along a direction perpendicular to the first direction, and the receiving groove is the holding space 300. In an actual installation process, the flat observed object 4 may be installed in the holding space 300 through the notch of the receiving groove, or an opening penetrating through the receiving groove may be formed in the holding module 3 and/or the magnifier module 2, so that the flat observed object 4 may be inserted into the holding space 300 through the opening.

As another alternative, as shown in fig. 7, fig. 7 shows that the clamping module is formed with a receiving groove, and the magnifier housing is formed with a receiving groove, the receiving groove forming the clamping space. The first side 221 of the magnifier housing 22 forms a receiving groove extending in the transverse direction, the receiving groove has a vertical opening (not labeled) deviating from the first direction and at least one transverse opening 324 extending through the magnifier housing 22 in the transverse direction, when the holding module 3 is connected to the magnifier housing 22, a holding space 300 is formed between the bottom surface of the receiving groove and the portion of the holding module 3 corresponding to the vertical opening, and the flat observed object 4 can be inserted into the holding space 300 through the transverse opening 324.
As yet another alternative, fig. 8 shows that the clamping module is formed with a first groove part, while the magnifier housing is formed with a second groove part, which together form the clamping space, as shown in fig. 8. Form one along the storage tank of horizontal extension between grip module 3 and the magnifying glass casing 22, the storage tank has at least one along transversely running through grip module 3 and the horizontal opening 324 of magnifying glass casing 22, the storage tank is including locating the first accommodation slot part 300a of grip module 3 and locating the second accommodation slot part 300b of magnifying glass casing 22, when grip module 3 connects in magnifying glass module 2, form clamping space 300 between the bottom surface of first accommodation slot part 300a and the bottom surface of second accommodation slot part 300b, the thing can be observed through horizontal opening insert in clamping space 300 to the platykurtic.
Further, the accommodating groove can be provided with two transverse openings which are communicated with each other in a transverse direction. When the flat observed object 4 is inserted into the holding space 300, the two ends of the flat observed object 4 can extend out of the holding space 300 through the corresponding openings, so that an operator can conveniently move the flat observed object 4 in the transverse direction by holding the end of the flat observed object 4 by hand, and replace the observation position of the flat observed object 4, so that the real object on the flat observed object 4 is aligned with the lens assembly 23, and the operation mode is convenient.
In some embodiments, as shown in fig. 9, the clamping module 3 includes an upper casing 321 and a lower casing 322, the upper casing 321 and the lower casing 322 are sequentially disposed along a first direction (a direction indicated by an upward arrow in fig. 9), an accommodating groove is formed between the upper casing 321 and the lower casing 322 and transversely penetrates through the clamping module 3, the lower casing 322 is provided with a vertical opening facing the first side 221 of the magnifier casing 22, and when the clamping module 3 is connected to the magnifier casing 22, the first side 221 of the magnifier casing 22 abuts against the vertical opening.
Further, when the clamping module 3 is connected to the magnifier housing 22, the first side 221 of the magnifier housing 22 abuts against the vertical opening and at least partially extends into the accommodating groove, so that the flat observed object 4 is conveniently attached to the magnifier module 2 when the flat observed object 4 is inserted into the clamping space 300.
In some embodiments, the upper housing 231 has a mounting cavity therein, and the clamping module 3 further includes an elastic member, the elastic member is disposed in the mounting cavity and at least partially extends into the receiving cavity, and the elastic member is configured to apply a force toward the first direction to the flat observed object 4 inserted into the receiving cavity, so that the flat observed object 4 is tightly attached to the lens assembly 23. That is, when the flat observed object 4 is inserted into the holding space 300, the elastic member is pressed by the flat observed object 4 to deform, so that the height h of the holding space 300 can be adapted to the flat observed object 4 with different thicknesses. Meanwhile, in this process, the flat observed object 4 can be pressed towards the lens assembly 23 by the acting force generated when the elastic member is pressed by the flat observed object 4, and the flat observed object 4 is tightly attached to the lens assembly 23, so that the flat observed object 4 can be kept at the observation position of the optimal optical path/preset optical path of the lens assembly 23, and a clear magnified image can be obtained.
Further, as shown in fig. 10 and 11, the upper housing 231 may include a supporting plate 3212 and a first housing 3211 sequentially disposed along the first direction, the first housing 3211 and the supporting plate 3212 are connected and matched to form the aforementioned mounting cavity, the elastic element may include a fixing portion 313, an elastic portion 314 and a contact portion 311 sequentially connected, the fixing portion 313 may be fixedly connected to the supporting plate 3212, the contact portion 311 may penetrate through the supporting plate 3212 and extend into the receiving cavity, the elastic portion 314 is configured to provide a force toward the first direction when the contact portion 311 abuts against the flat observed object 4 inserted into the receiving cavity, so that the flat observed object 4 may cling to the lens component 23, and the flat observed object 4 may be maintained at an observation position of the optimal optical path/preset optical path of the lens component 23, so as to obtain a clear enlarged image.
Exemplarily, in order to realize that the fixing portion 313 is fixedly connected to the bearing plate 3212, the fixing portion 313 is provided with a connecting hole 312, one surface of the bearing plate 3212 located in the installation cavity is provided with a hot-melting column 3213, when the elastic element is assembled, the connecting hole 312 of the elastic element may be sleeved on the hot-melting column 3213, and then the hot-melting column is heated to melt, so as to fixedly connect the fixing portion 313 to the bearing plate 3212. Moreover, when the elastic member is pressed by the flat observed object 4, the elastic member can move relative to the bearing plate 3212 and enter the installation cavity or extend into the receiving cavity 323, so that the clamping space 300 is adapted to the flat observed object 4 with different thicknesses. The carrier plate 3212 may be a metal plate, such as a steel plate.
In some embodiments, the outer surface of the contact portion 311 may be spherical, so that when the flat observed object 4 is inserted into the holding space 300, the contact portion 311 may make spherical contact (point contact) with the flat observed object 4, thereby being capable of reducing the friction between the contact portion 311 and the flat observed object 4 when the flat observed object 4 is laterally moved, and facilitating the movement of the flat observed object 4.
The elastic member may be a metal member (e.g., a metal spring), a silica gel column, a rubber column, a foam column, or a spring, which has elastic deformation capability. Preferably, the elastic portion 314 may be an elastic steel sheet, and the elastic steel sheet is used as an elastic member, so that the surface of the elastic member is relatively smooth, the flat observed object 4 can be moved in the length direction of the clamping module 3, the friction force between the contact portion 311 and the flat observed object 4 is reduced, and the flat observed object 4 can be conveniently moved; moreover, since the thickness of the elastic steel sheet is generally small, the occupied space is small, which is beneficial to the light and thin design of the upper shell 321.
Further, the contact portion 311 is coated with a material for reducing friction, such as ink or talc, to reduce friction between the flat observed object 4 and the contact portion 311 when the flat observed object 4 is laterally moved.
In some embodiments, a vertical opening of the lower housing 322 is provided with a limiting portion 3221, the limiting portion 3221 is used for abutting against the first side 221 of the magnifier housing 22 to limit the magnifier housing 22 to extend into the accommodating groove, that is, when assembling, the first side 221 of the magnifier housing 22 may abut against the limiting portion 3221, so as to limit the magnifier module 2 to move relative to the lower housing 322 along the optical axis direction thereof, so as to avoid the magnifier module 2 from extending into the accommodating groove 323 to have an excessively large thickness, which results in a small range of the height of the clamping space 300, and thus it can be ensured that the clamping space 300 can be loaded with flat observed objects 4 with all conventional thicknesses.
Exemplarily, the vertical opening of the lower housing 322 is provided with a limiting bevel edge extending downward (i.e. the direction of the lower housing 322 towards the magnifier housing 22, as indicated by arrow y in fig. 12) and inclining outward, the limiting bevel edge forms the aforementioned limiting portion, the end surface of the first side 221 of the magnifier housing 22 is provided with a limiting bevel 20 cooperating with the limiting bevel edge, when the first side 221 of the magnifier housing 22 abuts against the vertical opening, the limiting bevel 20 abuts against the limiting bevel edge and the first side 221 of the magnifier housing 22 at least partially extends into the accommodating groove.

The light emitting portion 244 may be an annular light emitting surface disposed around the second opening 241 b. In fig. 1, an axis a of the mounting hole 241 is indicated by a dotted line a, and a dotted line plane xy indicates a plane perpendicular to the axis a of the mounting hole 241. When the lens assembly 23 is mounted in the mounting hole 241, the optical axis of the lens assembly 23 coincides with the axis a of the mounting hole 241.
On one hand, in the present embodiment, the lens assembly 23 is installed through the installation hole 241, the image side end 232 and the object side end 231 of the lens assembly 23 face the first opening 241a and the second opening 241b, the light emitting portion 244 for emitting light to the outside of the installation hole 241 is disposed at the periphery of the second opening 241b, and an external light source (such as the aforementioned light source) is used to provide incident light to the light inlet portion 240 and conduct the incident light to the light emitting portion 244 to emit light under the light guiding effect of the light guiding member 24, so that when the object side end 231 of the lens assembly 23 is observed near an object to be observed, for example, when the flat observed object 4 is inserted into the clamping space 300, the light emitted by the light emitting portion 244 can illuminate the object to be observed (such as the aforementioned flat observed object), and the observation clarity is improved. The light guide 24 itself cannot emit light, and the external light source is a light source independent of the light guide 24, for example, the external light source may be a flash lamp of an intelligent terminal or a light source of a magnifying glass module, a flashlight, and the like.
It is understood that in practical applications of the light guide 24, the light inlet 240 needs to be close to an external light source, the object side 231 of the lens assembly 23 needs to be close to an object to be observed, and the image side 232 needs to be close to eyes of a user for the user to directly observe the object to be observed or close to the camera 11 of the smart terminal 100 for the camera 11 to shoot. That is, in practical applications, the light guide 24 needs to consider the arrangement of each participating object (such as an object to be observed, an external light source, a user, a camera, etc.) to avoid interference when each participating object is arranged, so that the light inlet portion 240 cannot be overlapped with the light outlet portion 244. Therefore, in the present embodiment, the position of the light inlet portion 240 is deviated from the position of the light outlet portion 244 in the plane perpendicular to the axis a of the mounting hole 241, so that interference between the respective participating objects in the actual application of the light guide member 24 is avoided, and the light guide member 24 can be used normally. Specifically, the light guide 24 includes a first surface 24a and a second surface 24b that are disposed opposite to each other, the first surface 24a has the light entrance portion 240, the mounting hole 241 penetrates the first surface 24a and the second surface 24b, the first opening 241a is located on the first surface 24a, and the second opening 241b is located on the second surface 24 b.

Further, it is considered that the light guide member 24 cannot simply directly transmit the incident light received by the light inlet portion 240 to the light outlet portion 244, for example, transmit the light along a straight line, due to the position relationship between the light inlet portion 240 and the light outlet portion 244. Therefore, in the present embodiment, the light guiding path of the light guiding member 24 is designed, and the light splitting structure 242 and the reflection structure are used to substantially transversely conduct the incident light entering the light entering portion 240 substantially along the vertical direction and then vertically conduct the incident light to the light exiting portion 244, wherein the substantially transverse conduction is mainly used to compensate the deviation position of the light entering portion 240 and the light exiting portion 244, so that the incident light can smoothly reach the light exiting portion 244 and exit the mounting hole 241.
Moreover, when the light splitting structure 242 and the reflection structure transmit incident light, the light splitting structure 242 can split the incident light into at least two paths of sub-light, and transmit each path of sub-light to different light emitting positions of the light emitting portion 244 through the reflection structure, so that the light transmitting uniformity of the light emitting portion 244 is improved, and when the transmitted light irradiates to an object to be observed, the brightness of the object to be optically wiped is uniform, so that the observation definition is further improved.

It can be understood that, through the light splitting action of the first light splitting surface 242a and the second light splitting surface 242b, the first sub light and the second sub light are formed, and the first reflecting surface group 2431 and the second reflecting surface group 2432 are utilized to respectively conduct the first sub light and the second sub light to the first position and the second position, so that the light emitting part 244 transmits light to the outside of the mounting hole 241 at the two light emitting positions, the light transmitting part 244 transmits light more uniformly, and the phenomenon that the light is concentrated at a certain position of the light emitting part 244 and is transmitted out is avoided, so that a partial area of an object to be observed is darker, the partial area is lighter, and the condition of the observation definition is influenced occurs.
Alternatively, the first position and the second position are symmetrically disposed about the center plane yz of the mounting hole 241. It is understood that the first position and the second position are designed to make the light-emitting portion 244 transmit light more uniformly.
