The technical scheme of the invention will be further described with reference to the examples and the accompanying drawings.
The embodiment of the invention discloses an externally hung microscope which can be applied to an intelligent terminal for amplifying observation or shooting, wherein the intelligent terminal comprises a terminal shell and a camera, and the microscope can comprise a magnifying glass module and a clamping module. The magnifier module can be configured to be detachably fixed on the terminal housing, the camera is used for collecting optical signals passing through the magnifier module when the magnifier module is fixed on the terminal housing, and the clamping module is configured to be detachably connected with the magnifier module and/or the terminal housing, and a clamping space for arranging a flat observed object is formed between the clamping module and the magnifier 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 movement, the shaking or the inclination of the intelligent terminal in the amplifying observation process can be avoided, and the problem that the flat observed object cannot be clearly observed due to the movement, the shaking or the inclination of the intelligent terminal is solved, that is, even if the intelligent terminal is moved, the shaking or the inclination of the intelligent terminal in the amplifying observation process, the flat observed object can be clearly observed.
It is understood that the formation of the holding space for setting the flat observed object between the magnifier module and the holding module means: 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 magnifying glass 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 arranged in a hanging mode, the flat observed object can not fall off the clamping space due to the fact that the clamping space can clamp the flat observed object, that is, in the magnifying observation process, the intelligent terminal does not need to be placed on a placing plane (such as a tabletop, 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 magnifying glass module may be an optical device for observing minute details of an object, then "magnified imaging" may refer to: the flat observed object can be magnified by the magnifying lens module at high magnification, for example, a magnified image which is obtained after 10-60 times magnification and can be directly observed by eyes.
Reference herein to flat is to be understood as a structure, such as a lamellar structure, having a thickness which is much smaller than the length and/or width; the flat object to be observed in the present application is understood to be a slide glass, a specimen mount sheet, or a mount sheet attached with an object (object to be observed) for microscopic observation, and the specimen mount sheet may include a slide glass, a cover glass, and an object (i.e., an object to be observed such as an animal or plant specimen, a human tissue cell specimen, or blood, etc.) mounted between the slide glass and the cover glass for magnification observation. For example, when the flat observed object is a specimen mount, the flat observed object may be a specimen mount of a bee wing, a specimen mount of a mosquito mouth device, a specimen mount of an arteriovenous transection of a human body, or the like. It will be appreciated that the flat object to be observed may also be a specimen smear (e.g., a human blood permanent smear, a bacterial three-smear, etc.) or a specimen slice (a permanent cross-section of soybean stems or corn stems), etc.
In the actual assembly process, the clamping module can be used for being matched with the magnifying glass module to form a microscope, and then the magnifying glass module of the microscope is mounted on the terminal shell of the intelligent terminal, so that amplified observation or shooting of a flat observed object can be realized. Of course, the magnifier module may be mounted to the terminal housing of the intelligent terminal, and then the clamping module may be fixed to the magnifier module and/or the terminal housing of the intelligent terminal.
The intelligent terminal in the application can be an electronic device capable of improving learning efficiency, and has the functions of discipline teaching (electronic textbook, textbook knowledge point interpretation and post-class exercises), learning diagnosis (post-class exercises answers and conventional answers), intelligent answering (answering according to answering ideas of students), teacher confusion (playing recorded knowledge point videos of teachers and communicating with a teacher video screen to enable the teachers to solve the problems in real time) and the like, such as a tablet computer, a home teaching machine or a mobile phone. When the microscope is applied to a tablet computer, the magnifying glass module is mounted on the tablet computer, particularly detachably mounted at a position corresponding to a camera of the tablet computer and is arranged corresponding to the camera of the tablet computer, so that when the microscope is mounted on the tablet computer and a flat observed object is inserted into the clamping space, the flat observed object can be observed, and particularly micro-structures of microorganisms, cells or some substances can be observed.
In one application scenario, for example, when the microscope is applied to a tablet personal computer for children, most users are children, for example, children aged 2-8 years, the clamping space based on the microscope can clamp a flat observed object, and when the flat observed object is inserted into the clamping space, the magnifier module can be tightly attached to the flat observed object, so that clear amplified imaging is obtained, the operation and the use are convenient and simple, and the requirements of the children for popular science use can be well met.
It can be known that the child is generally better, and when in use, the tablet computer is likely to be moved frequently, but as the flat observed object can be clamped by the clamping space 300 and can move along with the tablet computer, the close fit degree of the flat observed object and the magnifier module cannot be affected in the moving process, so that the situation of virtual focus of the microscope cannot be caused even if the child moves the tablet computer, the observability of the microscope in the application can be greatly enhanced, early educational education of the child can be easier to carry out, and smooth progress of the educational education of the microscope can be ensured.
In addition, the microscope is used for the tablet personal computer of the child, not only can an enlarged image be displayed on a display screen of the tablet personal computer of the child so as to be convenient for observation, but also the tablet personal computer of the child can be used for explaining the specimen on the flat observed object so as to help the child to more comprehensively know and recognize the observed specimen.
The specific structure of the microscope and the specific connection manner of the microscope applied to the smart terminal and connected to the smart terminal will be described in detail.
Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of an intelligent terminal as a tablet computer according to an embodiment of the present invention. The intelligent terminal 100 includes a terminal housing 1, a camera 11 and a microscope 200, the terminal housing 1 is provided with a shooting window (not labeled), the camera 11 is arranged in the terminal housing 1 and views a view through the shooting window, the magnifier module 2 is configured to be detachably and fixedly connected to the terminal housing 1, when the magnifier module 2 is fixedly connected to the terminal housing, the camera 11 is abutted to the magnifier module and is used for collecting optical signals passing through the magnifier module 2, so that the camera 11 can obtain an image amplified by the magnifier module 2, and a user can observe a microstructure which cannot be directly resolved by naked eyes through the intelligent terminal 100. The holding module 3 is configured to be detachably connected to the magnifier module 2 and/or the terminal housing 1 and form a holding space for disposing the flat observed object 4 with the magnifier module 2.
The camera 11 is used to collect the optical signal passing through the magnifier module 2, which can be understood as: when the magnifier module 2 is fixed to the terminal housing 1, the optical path through the magnifier module 2 can enter the camera 11, so that the camera 11 can acquire the image amplified 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 indicated by arrow x in fig. 1.
It will be appreciated that the intelligent terminal 100 further includes a display screen and a main board, a battery, a speaker, a microphone, and components of a communication module, the display screen is disposed on the front surface of the terminal housing 1, and the camera 11 may be a front camera disposed on the front surface of the terminal housing 1 or a rear camera disposed on the rear surface 10 of the terminal housing 1. And the intelligent terminal 100 may further include an application icon used with the magnifier module 2, for example, when the magnifier module 2 is mounted to the terminal housing 1, the display screen may present magnified images of the camera 11 through the magnifier module 2 when the application icon is opened.
Illustratively, the camera 11 is a rear camera, and the magnifier module 2 is mounted on the back surface 10 of the terminal housing 1, so that a situation that the display screen is possibly blocked due to the fact that the microscope 200 is mounted on the front surface of the terminal housing 1 can be avoided. The magnifying glass module 2 of the microscope 200 may have a bar-like or block-like structure, and the holding module 3 of the microscope 200 may have a bar-like or block-like structure.
The clamping space of the present application can be adapted to be adjusted according to the thickness of the flat object 4 to adapt to the flat object 4 with different thickness, that is, when the flat object 4 with different thickness is inserted into the clamping space, the flat object 4 can be kept in close contact with the magnifier module 2.
In order to enable the clamping space to be adaptively inserted into flat objects 4 with different thicknesses, and the flat objects 4 with different thicknesses can be tightly attached to the magnifier 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 magnifier module 2. As an alternative embodiment, the clamping space 300 may be configured to be liftable and lowerable with respect to the magnifier module 2, such that the height h of the clamping space 300 is adapted to accommodate insertion of flat objects 4 of different thicknesses. That is, the clamping 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 clamping space 300 so that the height h of the clamping space 300 is adapted to insert flat objects 4 of different thicknesses, the height h of the clamping space 300 being the height of the clamping space 300 in the optical axis direction of the magnifier module 2.
By the design, under the state of observing the flat observed object 4, the flat observed object 4 with different thickness can be replaced under the condition that any one of the components of the magnifying glass module 2 and the clamping module 3 is not detached, and the operation is convenient; and 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 thickness can be clamped, so that the flat observed object 4 with different thickness can be tightly attached to the magnifier module 2, when the flat observed object 4 with different thickness is observed, the magnifier module 2 can realize accurate focusing, the focal length of the magnifier module 2 can be maintained to be optimized, clear and amplified imaging can be shown on the display screen of the intelligent terminal 100, and the flat observed object 4 can be clearly observed, that is, after the flat observed object 4 with different thickness is replaced each time, the magnifier module 2 is not required to be subjected to focusing operation again, the flat observed object 4 can be clearly observed, 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 elastic deformation capability, where the deformation component 31a may be connected to the clamping module 3 and the terminal housing 1, respectively, and when the flat observed object 4 is inserted into the clamping space 300, the flat observed object 4 presses the clamping module 3 to elastically deform the deformation component 31a, so that the clamping module 3 moves relative to the magnifier module 2 to adjust the height of the clamping space 300, adapt to the flat observed object 4 with different thicknesses, and meanwhile, the deformation component 31a is elastically deformed under the action of the clamping module 3, and in this process, the force generated by the deformation component 31a can enable the clamping module 3 to compress the flat observed object 4 towards the magnifier module 2, and enable the flat observed object 4 to cling to the magnifier module 2, so as to obtain a clear 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 usual flat-shaped object 4 to be observed being generally 0.9mm to 1.85 mm.
As an alternative embodiment, as shown in fig. 4, fig. 4 shows that the clamping module 3 is provided with a hold-down and that the height of the clamping space between the clamping module and the magnifier module remains fixed. The microscope 200 further comprises a pressing member 31, and the pressing member 31 can be used for applying a force to the flat observed object 4 inserted into the clamping space 300 in a first direction (opposite to or same with the optical axis direction of the magnifier module 2) to enable the flat observed object 4 with different thickness to be inserted into the clamping space 300 in a matching manner. That is, when the flat object 4 is inserted into the holding space 300, the pressing member 31 is pressed by the flat object to be observed and deformed, so that the height of the holding space 300 can be adapted to the insertion of the flat object 4 having different thicknesses. Meanwhile, in the process, the flat observed object 4 can be pressed towards the magnifier module 2 by utilizing 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, a clear amplified image can be obtained, and meanwhile, the situation that the flat observed object deviates from the observation position of the optical path and even falls off from the clamping space 300 due to the movement, shaking or tilting of the intelligent terminal 100 in the amplifying 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 effect of the pressing member 31.
It will be appreciated that the compression 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 pressing member 31 is one, the pressing member 31 may be provided on any one of the three members of the holding module 3, the magnifier module 2, and the terminal housing 1; when there are a plurality of pressing pieces 31, at least one of the holding module 3, the magnifier module 2, and the terminal housing 1 may be provided with the pressing pieces 31, for example, the plurality of pressing pieces 31 are provided in each of the holding 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 magnifier module 2 and the terminal housing 1 are provided with said hold-down element 31, and for another example, the clamping module 3, the magnifier module 2 and the terminal housing 1 are each provided with said hold-down element 31.
The height of the holding space 300 may be 1.85mm based on the thickness of the usual flat-shaped object 4 to be observed, which is generally 0.9mm to 1.85mm.
In some embodiments, the weight of the magnifier module 2 may be 5 g-7.2 g, e.g., 5g, 5.4g, 5.6g, 6.0g, 6.2g, 6.5g, 6.8g, or 7.2g, etc., and the weight of the clip module 3 may be 6 g-8.8 g, e.g., 6g, 6.4g, 6.6g, 6.0g, 7.2g, 7.5g, 7.8g, 8.2g, 8.4g, 8.8g, etc. Therefore, the magnifier module 2 and the clamping module 3 of the application are light in weight and convenient to carry, and when being assembled, the magnifier module 2 and the clamping module 3 are not required to be clamped by other clamping auxiliary equipment, so that the assembly is convenient, and when the magnifier module 2 and the clamping module 3 are assembled on the terminal shell 1, the whole weight of the assembled intelligent terminal 100 is still light, thereby being beneficial to the light-weight design of the intelligent terminal 100.
It can be appreciated that when the objects of use of the magnifier module 2, the clamping module 3 and the intelligent terminal 100 are children, the magnifier module 2, the clamping module 3 and the assembled intelligent terminal 100 are light in overall mass, so that the magnifier module is convenient for children to use, such as holding and moving. Moreover, in use, for convenience, the smart terminal 100 is usually supported by a stand so as to stand on a placement plane (e.g., a desktop or a table top) at an angle, thereby facilitating viewing of a display screen of the smart terminal. When the intelligent terminal 100 is supported and vertically placed on a placement plane through the support, the weight of the magnifier module 2 and the clamping module 3 is light, 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 intelligent terminal 100 can be prevented from being tilted due to the too heavy weight of the magnifier module 2 and the clip module 3.
In some embodiments, as shown in fig. 9, the width of the clamping module 3 is D1, 20mm +.d1 +.40mm, such as d1=20 mm, d1=24 mm, d1=28 mm, d1=32 mm, d1=36 mm, d1=40 mm, etc.; the length of the clamping module 3 is L1, 40mm is less than or equal to l1 is less than or equal to 70mm, such as l1=40 mm, l1=44 mm, l1=48 mm, l1=52 mm, l1=66 mm, l1=70 mm, etc. The width of the magnifier module 2 is D2, d2=1/4D 1 to 2/3D1, for example, d2=1/4D 1, d2=1/3D 1, d2=5/12D 1, d2=3/4D 1, d2=7/12D 1, d2=2/3D 1, or the like, and the length of the magnifier module is L2, l2=4/5L 1 to 10/11L1, for example, l2=4/5L 1, l2=9/11L 1, l2=46/55L 1, l2=47/55L 1, l2=48/55L 1, l2=49/55L 1, l2=10/11L 1, or the like. Therefore, the magnifying glass module 2 and the clamping module 3 are smaller and are convenient to carry, and after the magnifying glass module 2 and the clamping module 3 are assembled to the terminal shell 1, the whole volume of the assembled intelligent terminal 100 is still smaller, so that the miniaturized design of the intelligent terminal 100 is facilitated.
It will be appreciated that in other embodiments, the width D1 of the clamping module 3 may also be 18mm, 19mm, 41mm, 42mm, 44mm, etc.; the length L1 of the gripping module 3 may be 38mm, 39mm, 71mm, 73mm, 74mm, or the like.
In some embodiments, as shown in fig. 5, the magnifier module 2 may include a magnifier housing 22 and a lens assembly 23 disposed within the magnifier housing 22, such that the lens assembly 23 may be protected by the magnifier housing 22. The magnifier housing 22 includes a first side 221 and a second side 222 opposite to each other, the first side 221 has an object side lens aperture 2211, the second side 222 has an object side lens aperture 2221, the lens assembly 23 includes an object side end 231 and an image side end 232, the object side end 231 is disposed in the object side lens aperture 2211 of the first side 221, and the image side end 232 is disposed in the image side lens aperture 2221 of the second side 222. When the magnifier housing 22 is fixed to the terminal housing 1, the end face of the second side 222 is attached to the terminal housing 1; and when the clamping module 3 is fixed to the magnifier module 2 and/or the terminal housing 1, a clamping space 300 is formed between the end surface of the first side 221 of the magnifier housing 22 and the clamping module 3. The lens assembly 23 may include a lens barrel and one or more magnifying lenses provided in the lens barrel, among others. When the lens assembly 23 includes a plurality of magnifying lenses, the plurality of magnifying lenses can 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, as indicated by an upward arrow in fig. 5.
In some embodiments, as shown in fig. 6 to 8, a receiving groove is formed between the clamping module 3 and/or the magnifier module 2, the receiving groove extends along a direction perpendicular to the first direction, and the receiving groove is the clamping space 300. In the actual installation process, the flat observed object 4 may be installed in the holding space 300 through the notch of the accommodating groove, or the opening penetrating the accommodating groove may be formed on 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.
For convenience of description, the first direction may be a direction indicated by a downward arrow in fig. 6 to 8, and the lateral direction may be a direction indicated by a leftward arrow and a rightward arrow in fig. 6 to 8, respectively.
As an alternative embodiment, as shown in fig. 6, fig. 6 shows that the clamping module is formed with a receiving groove forming a clamping space. The holding module 3 forms a holding groove extending in a transverse direction, the holding groove has a vertical opening (not labeled) facing the first direction and at least one transverse opening 324 penetrating the holding module 3 in a transverse direction, when the holding module 3 is connected to the magnifier housing 22, a holding space 300 for setting the flat observed object 4 is formed between a bottom surface of the holding groove (i.e. a surface of the holding groove facing the magnifier housing 22) and the first side 221 of the magnifier housing 22, and the flat observed object 4 can be inserted into the holding space 300 through the transverse opening 324.
As another alternative embodiment, as shown in fig. 7, fig. 7 shows that the clamping module is formed with a receiving groove, while the magnifier housing is formed with a receiving groove, which forms a clamping space. The first side 221 of the magnifier housing 22 forms a receiving groove extending in a transverse direction, the receiving groove has a vertical opening (not labeled) facing away from the first direction and at least one transverse opening 324 extending transversely through the magnifier housing 22, when the clamping module 3 is connected to the magnifier housing 22, a clamping space 300 is formed between a bottom surface of the receiving groove and a portion of the clamping module 3 corresponding to the vertical opening, and the flat observed object 4 can be inserted into the clamping space 300 through the transverse opening 324.

Further, the accommodating groove may have two lateral openings penetrating therethrough in the lateral direction. When the flat observed object 4 is inserted into the clamping space 300, two ends of the flat observed object 4 can extend out of the clamping space 300 through corresponding openings, so that an operator can conveniently move the flat observed object 4 in the transverse direction by holding the end part of the flat observed object 4, and change the observation position of the flat observed object 4, so that a real object on the flat observed object 4 is aligned with the lens assembly 23, and the operation mode is more convenient.
In some embodiments, as shown in fig. 9, the clamping module 3 includes an upper housing 321 and a lower housing 322, where the upper housing 321 and the lower housing 322 are sequentially disposed along a first direction (as indicated by an upward arrow in fig. 9), a receiving groove passing through the clamping module 3 in a lateral direction is formed between the upper housing 321 and the lower housing 322, and the lower housing 322 is provided with a vertical opening facing the first side 221 of the magnifier housing 22, and 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.
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 convenient to be closely 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 is provided with a mounting cavity, and the clamping module 3 further includes an elastic member disposed in the mounting cavity and at least partially extending into the accommodating groove, where the elastic member is configured to apply a force to the flat observed object 4 inserted into the accommodating groove in a first direction, so that the flat observed object 4 is closely attached to the lens assembly 23. That is, when the flat object 4 is inserted into the holding space 300, the elastic member is pressed by the flat object 4 to deform, so that the height h of the holding space 300 can be adapted to insert the flat object 4 with different thickness. Meanwhile, in the process, the flat observed object 4 can be pressed towards the lens assembly 23 by utilizing the acting force generated when the elastic piece 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 enlarged image can be obtained.
Further, as shown in fig. 10 and 11, the upper housing 231 may include a carrying plate 3212 and a first housing 3211 sequentially disposed along a first direction, where the first housing 3211 is connected to and matched with the carrying plate 3212 to form the mounting cavity, the elastic member may include a fixing portion 313, an elastic portion 314 and a contact portion 311 sequentially connected to each other, the fixing portion 313 may be fixedly connected to the carrying plate 3212, the contact portion 311 may extend into the accommodating groove through the carrying plate 3212, and the elastic portion 314 is used to provide a force towards the first direction when the contact portion 311 abuts against the flat observed object 4 inserted into the accommodating groove, so that the flat observed object 4 may be closely attached to the lens assembly 23, and the flat observed object 4 may be kept at an observation position of an optimal optical path/a preset optical path of the lens assembly 23, so as to obtain a clear enlarged image.
For example, in order to fix the fixing portion 313 to the carrier plate 3212, the fixing portion 313 is provided with a connection hole 312, a hot-melt column 3213 is disposed on a surface of the carrier plate 3212 located in the installation cavity, when the elastic member is assembled, the connection hole 312 of the elastic member can be sleeved on the hot-melt column 3213, and the hot-melt column is heated to be melted, so that the fixing portion 313 is fixed to the carrier plate 3212. When the elastic member is pressed by the flat observed object 4, the elastic member can move relative to the carrier plate 3212 and enter the mounting cavity or extend out of the accommodating groove 323, so that the clamping space 300 is adapted to the flat observed object 4 with different thickness. The carrier plate 3212 may be a metal plate, for example, a steel plate.
In some embodiments, the outer surface of the contact portion 311 may be spherical, so that the contact portion 311 may form spherical contact (point contact) with the flat object 4 when the flat object 4 is inserted into the clamping space 300, thereby reducing friction between the contact portion 311 and the flat object 4 when the flat object 4 is laterally moved, and facilitating movement of the flat object 4.
Illustratively, the elastic member may be a metal member (e.g., a metal dome), a silicone column, a rubber column, a foam column, or a spring, etc., having elastic deformability. 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 smoother, the flat observed object 4 can be moved along the length direction of the clamping module 3, the friction between the contact portion 311 and the flat observed object 4 is reduced, and the flat observed object 4 is convenient to move; and the thickness of the elastic steel sheet is generally smaller, so that the occupied space is smaller, and the light and thin design of the upper shell 321 is facilitated.
Further, the contact portion 311 is coated with a material for reducing friction, such as ink or talc, to reduce friction between the flat object 4 and the contact portion 311 when the flat object 4 is moved laterally.
In some embodiments, a limiting portion 3221 is disposed at a vertical opening of the lower housing 322, the limiting portion 3221 is used for abutting against the first side 221 of the magnifier housing 22 to limit the position of the magnifier housing 22 extending into the accommodating groove, that is, when the magnifier housing 22 is assembled, the first side 221 of the magnifier housing 22 abuts 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 excessive thickness of the magnifier module 2 extending into the accommodating groove 323, and reduce the height range of the clamping space 300, thereby ensuring that the clamping space 300 can be loaded with flat objects 4 with all thicknesses.
Illustratively, a vertical opening of the lower housing 322 is provided with a limiting oblique edge extending downward (i.e., in a direction of the lower housing 322 toward the magnifier housing 22, as indicated by an arrow y in fig. 12) and inclined outward, the limiting oblique edge forms the aforementioned limiting portion, an end surface of the first side 221 of the magnifier housing 22 is provided with a limiting oblique surface 20 matched with the limiting oblique edge, and when the first side 221 of the magnifier housing 22 abuts against the vertical opening, the limiting oblique surface 20 abuts against the limiting oblique edge and the first side 221 of the magnifier housing 22 at least partially extends into the accommodating groove. In this way, when the flat object 4 is inserted into the holding space 300, the flat object 4 is easily brought into close contact with the lens assembly 23 of the magnifier module 2.
Further, the lower housing 322 is further provided with a receiving cavity 3223 with an opening facing the first direction, the receiving cavity 3223 is adapted to the magnifier housing 22 to at least partially receive the magnifier housing 22, and a bottom surface of the receiving cavity 3223 (i.e. a surface of the receiving cavity 3223 facing away from the upper housing) is provided with a vertical opening. That is, the lower housing 322 may be provided with a first side wall 3222, the first side wall 3222 and the limiting portion 3221 enclose to form a accommodating cavity 3223, and the magnifier module 2 is clamped in the accommodating cavity 3223, so that the accommodating cavity 3223 may play a positioning role during assembly.
It can be appreciated that the upper case 321 and the lower case 322 of the clamping module 3 are connected to form a receiving groove (clamping space 300), the lower case 322 is formed with a receiving cavity 3223 having a notch disposed opposite to the upper case 321, and the receiving cavity 3223 is communicated with the receiving groove. When the magnifier module 2 is assembled, the limiting inclined plane 20 of the magnifier module 2 will abut against the limiting inclined plane (i.e. the limiting part 3221) of the lower housing 322, at this time, the first side 221 of the magnifier housing 22 slightly extends into the accommodating groove and forms the clamping space 300 with the upper housing 321, so when the flat object 4 is inserted into the clamping space 300, the elastic member provided on the upper housing 321 will apply a pressing force towards the magnifier module housing 22 to the flat object 4, so that the flat object 4 can be tightly attached to the first side 221 of the magnifier housing 22, and further the magnified observation of the flat object 4 according to the designed optical path can be ensured, so as to obtain a clear magnified image.
In some embodiments, as shown in fig. 13 to 15, a flange 12 is disposed at a position of the back surface 10 of the terminal housing 1 corresponding to the periphery of the rear camera, a groove 21 is disposed at a position of the magnifier module 2 corresponding to the flange 12, and the groove 21 is in fit and clamping connection with the flange 12 so as to position the magnifier module 2 in the terminal housing 1. The arrangement of the groove 21 and the flange 12 can play a role in positioning when the magnifier module 2 is mounted to the terminal housing 1, so that after the magnifier module 2 is mounted to the terminal housing 1, the magnifier module 2 can be connected to the rear camera of the intelligent terminal 100 in a light path, the position of the magnifier module 2 relative to the terminal housing 1 can be adjusted in one step, the light path of the rear camera is aligned with the light path of the magnifier module 2, and the mounting is efficient.
Illustratively, trim of the rear camera forms the flange 12. This eliminates the need to provide a flange 12 on the rear surface 10 of the terminal housing 1, and can retain the original appearance effect of the rear surface 10 of the terminal housing 1.
In some embodiments, as shown in fig. 16 and 17, the magnifier module 2 may be magnetically connected to the terminal housing 1, while the clamping module 3 may also be magnetically connected to the magnifier module 2 and/or the terminal housing 1. It will be appreciated that in other embodiments the magnifying glass module 2 may also be snap-fit or screw-fit onto the terminal housing 1, while the clamping module 3 may also be snap-fit or screw-fit onto the magnifying glass module 2 and/or the terminal housing 1.
For example, the magnifier module 2 may be magnetically connected to the terminal housing 1, while the clamping module 3 may be magnetically connected to the magnifier module 2, so that the magnifier module 2 further includes a first magnetic member 25 disposed in the magnifier housing 22, and a second magnetic member 33 is disposed in the clamping module 3, for example, the second magnetic member 33 may be disposed on the carrier plate 3212 and located in the mounting cavity, and the second magnetic member 33 and the first magnetic member 25 are mutually attracted and connected to implement the connection of the clamping module 3 to the magnifier module 2. A third magnetic component (not shown) is disposed in the terminal housing 1, and the third magnetic component may be disposed corresponding to the first magnetic component 25, and the third magnetic component is connected to the first magnetic component 25 in a mutually attracting manner, so as to realize connection between the clamping module 3 and the magnifier module 2.

One of the first magnetic pole and the second magnetic pole is an N pole, and the other is an S pole. For example, when the first magnetic pole is N pole, the second magnetic pole is S pole, the third magnetic pole is S pole, and the fourth magnetic pole is N pole.

The first magnetic member 25 may be a cylindrical magnet, for example. Considering that the object of use of the magnifying glass module 2 of the present application can be a child of 2-8 years old, and a small part containing a magnet for use by a child of 2-8 years old, the magnetic flux of the magnet used by the small part is required to meet the safety requirement, for example, when the magnetic flux index of the magnet is greater than 50, the length of the magnet is not more than 32mm, and the diameter of the magnet is not more than 11mm. Therefore, in order to make the first magnetic component 25 not only meet the requirement of safety indication, but also make the first magnetic component 25 and the second magnetic component 33, and make the first magnetic component 25 and the third magnetic component have larger magnetic attraction force, the first magnetic component 25 may be designed into a plurality of cylindrical magnets with lengths not exceeding 32mm and diameters not exceeding 11mm, and the plurality of first magnetic components 25 are arranged at intervals.
Further, the second magnetic components 33 may be plural, and the plural second magnetic components 33 are arranged at intervals and respectively correspond to the plural first magnetic components 25 one by one; or the second magnetic member 33 may be one, and the plurality of first magnetic members 25 are respectively connected with the second magnetic member 33 in a mutually attracting manner. Likewise, the number of the third magnetic components can be plural, and the plural third magnetic components are arranged at intervals and respectively correspond to the plural first magnetic components 25 one by one; or the third magnetic member may be one, and a plurality of third magnetic members are respectively connected with the second magnetic member 33 in a mutually attracting manner.
It can be understood that, in order to improve the connection stability between the magnifier module 2 and the clamping module 3, and between the magnifier module 2 and the terminal housing 1, the magnifier module 2 and the clamping module 3 may have a strip structure, and the plurality of first magnetic components 25 may be divided into two groups of first magnetic components, where the two groups of first magnetic components 25 are respectively located on two sides of the magnifier module 2 in the length direction. Correspondingly, the clamping module 2 is provided with second magnetic components 33 corresponding to the two groups of first magnetic components 25, and the terminal housing 1 is provided with third magnetic components corresponding to the two groups of first magnetic components 25. The length direction of the magnifier module 2 is indicated by arrow z in fig. 15.
In some embodiments, as shown in fig. 16 and 17, the magnifier module 2 further includes a light guide 24, where the light guide 24 is disposed in the magnifier housing 22, and the light guide 24 may be used for guiding light to the object side end 231 of the lens assembly 23, so that the light may be irradiated to the flat observed object 4, so that the lens assembly 23 obtains a clear magnified image. The light guide 24 is provided in the magnifier housing 22, and the light guide 24 can be protected by the magnifier housing 22. Specifically, the magnifier housing 22 may include a top case 224 and a bottom case 223, the top case 224 and the bottom case 223 being connected to form a placement cavity, the lens assembly 23, the light guide 24 being disposed in the placement cavity, the bottom case 223 having a second side 222, the top case 224 having a first side 221. Specifically, the bottom case 223 may include a second housing 2231 and a cover plate 2232, where the second housing 2231 is connected to the top case 224, the second housing 2231 is provided with a first weight-reducing groove 2233 corresponding to the position of the light guide 24, and the cover plate 2232 is connected to the second housing 2231 to cover the opening of the first weight-reducing groove 2233 and clamp and fix the light guide 24 between the second housing 2231 and the top case 224. The weight of the bottom chassis 223 can be reduced by providing the first weight-reducing groove 2233, since the lightweight design of the magnifier module 2 is facilitated. Further, an annular flange 2234 is disposed on a side of the second housing 2231 facing away from the top case 224, and a cover plate 2232 is connected to a side of the top case 2231 facing away from the top case 224, wherein the cover plate 2232 and the annular flange 2234 form the recess 21.

In some embodiments, as shown in fig. 18 and 19, the top case 224 may be a strip-shaped case, the image side lens hole 2211 may be approximately located at a middle position of the top case 224, the light guide 24 and the lens assembly 23 may be approximately located at a middle position of the top case 224, and the two sets of first magnetic components 25 are respectively located at two sides of the top case 224 in the length direction, so that the connection stability of the magnifier module 2 and the clamping module 3 and the connection stability of the magnifier module 2 and the intelligent case can be achieved, and at the same time, the space for placing the cavity is reasonably arranged, so that the layout of the first magnetic components 25, the light guide 24 and the lens assembly 23 on the top case 224 is relatively regular.
Illustratively, the top case 224 is provided with a plurality of spaced ribs 2241 on one surface of the placement cavity, the ribs 2241 define a fixing slot 2242, the first magnetic member 25 is fixed in the fixing slot 2242, for example, the first magnetic member 25 may be fixed in the fixing slot 2242 by dispensing, and the bottom of the fixing slot 2242 is provided with ventilation holes 2243. Thus, when the first magnetic member 25 is inserted into the fixing groove 2242, the first magnetic member 25 compresses air of the fixing groove 2242, resulting in the compressed air in the fixing groove 2242 generating a pushing force against the first magnetic member 25, which is disadvantageous for the fixing of the first magnetic member 25 in the fixing groove 2242. In the application, the air holes are arranged at the bottom of the positioning groove, so that the pressure intensity between the first magnetic component 25 and the fixing groove 2242 can be avoided, and the connection stability of the first magnetic component 25 and the fixing groove 2242 can be enhanced. In addition, when the first magnetic part 25 needs to be disassembled, a thimble can be used to push the first magnetic part 25 from the air hole, so as to facilitate the disassembly of the first magnetic part 25.
Further, the second housing 2231 is provided with the second weight-reducing groove 2235 at a position corresponding to the first magnetic member 25, so that the weight of the bottom chassis 223 can be further reduced.
As an alternative embodiment, the magnifier module 2 further includes a light source (not shown) disposed within the magnifier housing 22, i.e., the light source may be disposed within the placement cavity, and the light guide 24 is disposed at least partially corresponding to the light source, such that light emitted by the light source may be transmitted through the light guide 24 to the object side end 232 of the lens assembly 23. The light source may be spaced from the light guide 24, or may be disposed on the light guide 24.
As another alternative embodiment, the intelligent terminal 100 further includes a light source disposed on the terminal housing 1, and when the magnifier housing 22 is fixed on the terminal housing 1, the light guide 24 is disposed at least partially corresponding to the light source, so that the light emitted by the light source can be transmitted to the object side end 232 of the lens assembly 23 through the light guide 24. In this way, the light source does not need to be additionally arranged in the magnifier module 2, so that the occupation of the internal space of the magnifier module 2 by the light source can be avoided, thereby being beneficial to the miniaturization design of the magnifier module 2.
Further, in order to facilitate the observation, the method can quickly enter a mode of clearly observing the flat observed object 4, reduce the operation of a user, and based on the characteristics of no electric shock, low energy consumption, long service life, quick response frequency and the like of the hall switch, the hall switch (not shown) is arranged in the terminal housing 1, the position of the magnifier module 2 corresponding to the hall switch is provided with a fourth magnetic component 26, and the fourth magnetic component 26 is used for being connected with or disconnected from the hall switch, so that the hall switch controls the starting or closing of the light source on the terminal housing. For example, when the application icon on the smart terminal 100 is opened, once the magnifier module 2 is assembled to the terminal housing 1, the fourth magnetic member 26 can be quickly turned on with the hall switch to quickly activate the light source on the terminal housing; conversely, once the magnifier module 2 is detached from the terminal housing 1, the fourth magnetic member 26 is disconnected from the hall switch, so as to quickly turn off the light source on the terminal housing, and the smart terminal 100 is not required to be additionally pressed or touched, so that the operation is simpler. Wherein the fourth magnetic member 26 may be a magnet.
In some embodiments, the light source provided on the terminal housing 1 may be a flash 13, a led lamp, or the like. When the light source on the terminal housing 1 is the flash lamp 13, the flash lamp 13 is arranged in the terminal housing 1, that is, the magnifying glass module 2 can utilize the original flash lamp 13 of the intelligent terminal 100 as a light source, the terminal housing 1 does not need to be additionally provided with the light source, the internal space of the terminal housing 1 is not required to be occupied, the increase of the whole quality of the intelligent terminal 100 is not caused, the intelligent terminal 100 is beneficial to conforming to the miniaturization design and the light weight design, and the cost can be reduced.
Referring to fig. 20 to 22, the light guide 24 includes a light inlet 240, a mounting hole 241, a light splitting structure 242 and a reflecting structure, wherein the light inlet 240 is configured to receive incident light, for example, to receive light from the light source, the mounting hole 241 includes a first opening 241a and a second opening 241b, the mounting hole 241 is configured to mount the lens assembly 23, the image side end 232 faces the first opening 241a, the object side end 221 faces the second opening 241b, a light outlet 244 is disposed at an outer periphery of the second opening 241b to transmit light to the outside of the mounting hole 241, the light inlet 240 is offset from the light outlet 244 in a plane perpendicular to an axis a of the mounting hole 241, the light splitting structure 242 is disposed corresponding to the light inlet 240, the light splitting structure 242 is configured to split the incident light received by the light inlet 240 into at least two sub-lights, and the reflecting structure is configured to transmit each sub-light to different light outlet positions of the light outlet 244.
The light emitting portion 244 may be an annular light emitting surface disposed around the second opening 241 b. The axis a of the mounting hole 241 is indicated by a broken line a in fig. 1, and the broken 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 the other hand, in the present embodiment, the lens assembly 23 is mounted through the mounting hole 241, and 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, respectively, and the light emitting portion 244 for transmitting light to the outside of the mounting hole 241 is disposed at the outer periphery of the second opening 241b, and the external light source (such as the aforementioned light source) is utilized to provide the incident light to the light inlet portion 240 and transmit the incident light to the light emitting portion 244 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 close to the object to be observed for example, when the flat observed object 4 is inserted into the clamping space 300, the light emitted from the light emitting portion 244 can illuminate the object to be observed (such as the aforementioned flat observed object), thereby improving the definition of observation. The light guide 24 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 magnifier module, a flashlight, etc., which is not limited in this embodiment.
It can be understood that, in practical application, the light guide 24 needs to be close to the external light source, the object side end 231 of the lens assembly 23 needs to be close to the object to be observed, and the image side end 232 needs to be close to the eyes of the user for the user to directly observe the object to be observed or close to the camera 11 of the intelligent terminal 100 for the camera 11 to shoot. That is, in practical application, 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.), so that interference is avoided when each participating object is arranged, and therefore 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 as to avoid interference between the respective participating objects of the light guide 24 during actual application, and ensure that the light guide 24 can be used normally. Specifically, the light guide 24 includes a first surface 24a and a second surface 24b disposed opposite to each other, the first surface 24a has the light inlet 240, the mounting hole 241 penetrates through 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 24b. It will be appreciated that, in practical applications, the first surface 24a of the light guide 24 may face the user, the camera, the external light source, and the second surface 24b may face the object to be observed.
Further, it is considered that the positional relationship between the light inlet portion 240 and the light outlet portion 244 causes that the light guide 24 cannot simply directly guide the incident light received by the light inlet portion 240 to the light outlet portion 244, for example, guide the light along a straight line. Therefore, the light guiding path of the light guiding member 24 is designed according to the present embodiment, the light splitting structure 242 and the reflecting structure are used to conduct the incident light entering the light inlet 240 approximately vertically and then conduct the incident light vertically to the light outlet 244, wherein the lateral conduction is mainly used to compensate the offset positions of the light inlet 240 and the light outlet 244, so that the incident light can smoothly reach the light outlet 244 and pass out of the mounting hole 241.
And, when the light splitting structure 242 and the reflecting structure transmit incident light, the light splitting structure 242 can divide the incident light into at least two sub-light, and transmit each sub-light to different light-emitting positions of the light-emitting portion 244 through the reflecting structure, so that the light transmission uniformity of the light-emitting portion 244 is improved, and when the transmitted light irradiates the object to be observed, the brightness of the object to be optically wiped is more uniform, so that the definition of the observation is further improved.
On the other hand, the lens assembly 23 is mounted through the mounting hole 241 of the light guide 24 in this embodiment, so that the overall structure of the magnifier module 2 is more compact, which is beneficial to reducing the overall volume of the magnifier module 2.
In some embodiments, the light splitting structure 242 includes a first light splitting surface 242a and a second light splitting surface 242b, the first light splitting surface 242a and the second light splitting surface 242b are inclined towards the light inlet portion 240, the first light splitting surface 242a and the second light splitting surface 242b can reflect incident light in different directions and form a first sub-light and a second sub-light, the reflecting structure includes a first reflecting surface set 2431 and a second reflecting surface set 2432, the first reflecting surface set 2431 is used for conducting the first sub-light to a first position of the light outlet portion 244, the second reflecting surface set 2432 is used for conducting the second sub-light to a second position of the light outlet portion 244, and the second position and the first position are different light outlet positions of the light outlet portion 244. It can be understood that, by the light splitting effect 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 reflection surface set 2431 and the second reflection surface set 2432 are used to respectively transmit the first sub-light and the second sub-light to the first position and the second position, so that the light emitting portion 244 transmits light to the outside of the mounting hole 241 at two light emitting positions, the light transmission of the light emitting portion 244 is relatively uniform, and the situation that the light is concentrated at a certain position of the light emitting portion 244 and transmitted out, which results in darker partial area, brighter partial area and influence on the definition of the observation of the object to be observed is avoided.
