Referring to fig. 1 to 2, fig. 1 is a schematic structural diagram of an electronic device 10 according to an embodiment of the application, and fig. 2 is an exploded structural diagram of the electronic device 10 in fig. 1.

The electronic device 10 provided in the embodiment of the present application may be a device with a shooting function, such as a mobile phone, a tablet computer, a notebook computer, and a smart watch, and the following description will be made with the electronic device 10 as a mobile phone. As shown in fig. 1-2, an electronic device 10 may include: the device comprises a housing 100, a display module 200 and an imaging mechanism 300. The housing 100 may be connected to the display module 200 and encloses a receiving space 101 with the display module 200. The camera mechanism 300 may be disposed in the accommodating space 101, and may be used to receive light outside the electronic device 10 for imaging. The image capturing mechanism 300 is used for implementing front-end image capturing of the electronic device 10, and may also be used for implementing rear-end image capturing of the electronic device 10. The front camera may be that the camera 300 receives light to form an image on a side close to the display module 200, and the rear camera may be that the camera 300 receives light to form an image on a side away from the display module 200.

The case 100 may be used for mounting various electronic devices required for the electronic apparatus 10, and the case 100 may form the accommodating space 101 together with the display module 200. As shown in fig. 2, the case 100 may include: a middle frame 110 and a rear cover 120. The display module 200 may be covered on one side of the middle frame 110, the rear cover 120 may be covered on the other opposite side of the middle frame 110, and the three may be enclosed together to form the accommodating space 101. Wherein the receiving space 101 may be divided into a first receiving space 1011 and a second receiving space 1012. The first accommodating space 1011 may be formed by surrounding the display module 200 and the middle frame 110 together, and may be used for installing electronic devices such as an optical sensor, so as to realize functions such as fingerprint unlocking, automatic screen-off and brightness self-adjustment. The second receiving space 1012 may be formed by surrounding the rear cover 120 and the middle frame 110 together, and may be used for mounting electronic devices such as a microphone, a speaker, a flash, a circuit board, and a battery, so as to perform functions such as voice communication, audio playing, and lighting. The imaging mechanism 300 may be disposed in the first accommodation space 1011 to perform front-end imaging, or may be disposed in the second accommodation space 1012 to perform rear-end imaging. Alternatively, the first accommodation space 1011 and the second accommodation space 1012 may be provided with the image pickup mechanism 300 at the same time. Accordingly, the rear cover 120 and the display module 200 may be provided with a light-transmitting area 102 corresponding to the image capturing mechanism 300 so that the image capturing mechanism 300 receives external light.

The middle frame 110 and the rear cover 120 may be made of glass, metal, hard plastic, etc., so that the middle frame 110 and the rear cover 120 have a certain structural strength. The materials of the middle frame 110 and the rear cover 120 may be the same, and since the middle frame 110 and the rear cover 120 are generally directly exposed to the external environment, the middle frame 110 and the rear cover 120 may also have a certain performance of wear resistance, corrosion resistance, scratch resistance, etc., or a layer of functional material for wear resistance, corrosion resistance, scratch resistance may be coated on the outer surfaces of the middle frame 110 and the rear cover 120 (i.e., the outer surfaces of the electronic device 10). In addition, in some embodiments, a corresponding brand identification (LOGO) may be disposed on the middle frame 110 and the rear cover 120 to beautify the appearance of the electronic device 10 and improve brand recognition. All directional indications (such as up, down, left, right, front, back … …) in the embodiments of the present application are merely used to explain the relative positional relationship, movement, etc. between the components in a particular gesture (as shown in the drawings), and if the particular gesture changes, the directional indication changes accordingly.

Further, the middle frame 110 may be used to mount the electronic components of the electronic apparatus 10 to fix the electronic components within the accommodating space 101. As shown in fig. 2, the middle frame 110 may include: middle plate 111 and rim 112. The middle plate 111 may be used to carry the camera mechanism 300 to fix the camera mechanism 300 within the accommodating space 101. For example, screw holes or adhesive may be provided on the middle plate 111, so that the image capturing mechanism 300 may be fixed to the middle plate 111 by screwing or bonding. Of course, midplane 111 may also be used to carry other electronics as desired for electronic device 10. The frame 112 may be formed by extending a sidewall of the middle plate 111 in a thickness direction of the middle plate 111, so that two opposite sides of the middle frame 110 may form a corresponding open structure. The display module 200 may be disposed on the open structure of one side of the middle frame 110, so as to form a first accommodating space 1011 together with the middle frame 110. The rear cover 120 may cover an open structure provided at the other opposite side of the middle frame 110 to form a second receiving space 1012 together with the middle frame 110. Meanwhile, the display module 200 and the rear cover 120 may be fixedly connected with the middle frame 110 by using an adhesive and/or a buckle, so as to improve the structural strength of the three.

The middle plate 111 and the frame 112 may be an integral structure, and the two may be integrally formed by injection molding, stamping, heat absorption molding, and the like. Of course, the middle plate 111 and the frame 112 may be two independent structural members, which may be connected by one or a combination of assembly methods such as clamping, bonding, welding, and the like. In some embodiments, the middle frame 110 may be provided with only the frame 112, and the display module 200 may be disposed on one side of the frame 112, and the rear cover 120 may be disposed on the other opposite side of the frame 112. Thus, the three components can still be enclosed together to form the accommodating space 101 for mounting the imaging mechanism 300 and other electronic devices of the electronic apparatus 10. In addition, in some embodiments, the back cover 120 may be further designed with a membrane such as a texture, a gradient color, a photochromic, and an electrochromic, to enhance the appearance of the electronic device 10.

The display module 200 may be used to provide an image display function for the electronic device 10, and when a user uses the photographing function of the electronic device 10, the display module 200 may present an imaging screen of the camera mechanism 300 for the user to observe and operate. The display module 200 may be covered on one side of the middle frame 110, and the two may be adhered and fixed by adhesive. The display module 200 may include a transparent cover plate, a touch panel, and a display panel that are sequentially stacked. The surface of the transparent cover plate can have the characteristics of smoothness so as to facilitate touch operations such as clicking, sliding, pressing and the like. The transparent cover plate may be made of rigid material such as glass, or flexible material such as Polyimide (PI) and colorless Polyimide (Colorless Polyimide, CPI). The touch panel is disposed between the transparent cover plate and the display panel, and is configured to respond to a touch operation of a user, and convert the corresponding touch operation into an electrical signal to be transmitted to the processor of the electronic device 10, so that the electronic device 10 can respond to the touch operation of the user. The display panel is mainly used for displaying pictures and can be used as an interactive interface for indicating a user to perform the touch operation on the transparent cover plate. The display panel may employ an OLED (Organic Light-Emitting Diode) or an LCD (Liquid CRYSTAL DISPLAY) to realize the image display function of the electronic device 10. In this embodiment, the transparent cover plate, the touch panel and the display panel may be bonded together by using an adhesive such as OCA (Optically CLEAR ADHESIVE, optical adhesive), PSA (Pressure SENSITIVE ADHESIVE ) or the like.

Referring to fig. 3 to 5, fig. 3 is a schematic structural diagram of the camera mechanism 300 in fig. 2, fig. 4 is an exploded structural diagram of the camera mechanism 300 in fig. 3, and fig. 5 is a schematic structural diagram of a partial cross-section of the camera mechanism 300 along v-v in fig. 3.

The image capturing mechanism 300 may be disposed in the accommodating space 101, and the image capturing mechanism 300 may receive external light for imaging. As shown in fig. 3 to 5, the image pickup mechanism 300 may include: lens module 310, lens module 320 and photosensitive module 330. The lens module 310 may be disposed on one side of the lens module 320, the photosensitive module 330 may be disposed on the other opposite side of the lens module 320, and the light emitted into the accommodating space 101 may sequentially pass through the lens module 310 and the lens module 320 along the optical axis direction Z and irradiate onto the photosensitive module 330 to form an image, thereby implementing the photographing function of the electronic device 10. Meanwhile, the lens module 320 may be electrically connected to the photosensitive module 330, and may change the propagation path of the light to implement the zooming function of the camera mechanism 300. In addition, the lens module 320 has the advantages of low production cost and low manufacturing difficulty, which is not only beneficial to mass production of the lens module 320, but also improves the yield of the lens module 320.

The lens module 310 may be disposed opposite to the light-transmitting region 102, and may change a propagation path of the light emitted into the accommodating space 101 through the light-transmitting region 102, so that the light emitted into the accommodating space 101 may be irradiated onto the photosensitive module 330 for imaging. As shown in fig. 4 to 5, the lens module 310 may include: a mount 311 and a lens assembly 312. The mounting base 311 may be connected to the lens module 320, and the mounting base 311 may be located on the light incident side of the lens module 320. Meanwhile, the mounting seat 311 may be further provided with a light hole 3111 formed along the optical axis Z, and the light hole 3111 may be communicated with the lens module 320 and the side of the mounting seat 311 away from the lens module 320, and disposed opposite to the light transmitting area 102. The lens assembly 312 can be disposed in the light-transmitting hole 3111, and can be used to change the propagation path of the light incident from the light-transmitting region 102, such as converging or diverging, so that the light can be transmitted to the photosensitive module 330 along a predetermined path for imaging.

Further, the thickness of the mount 311 in the optical axis direction Z may be not more than 0.5mm, specifically may be 0.5mm, 0.45mm, 0.4mm, or the like. Meanwhile, the light-transmitting hole 3111 may be a circular hole, and the aperture of the light-transmitting hole 3111 in a direction away from the lens module 320 may be gradually reduced, only by requiring that the light-transmitting hole 3111 be capable of satisfying the amount of light required for imaging by the imaging mechanism 300. For example, the minimum aperture value of the light-transmitting hole 3111 may be 2.2mm. Thus, not only the stacking height of the imaging mechanism 300 in the optical axis direction Z can be reduced by using the thinner mount 311, but also the design area of the light transmitting region 102 can be reduced by using the light transmitting hole 3111 with a gradually decreasing aperture. Particularly, when the image capturing mechanism 300 is used as a front-end image capturing, the minimum aperture value of the light-transmitting hole 3111 can reduce the area of the light-transmitting region 102 required to be designed on the display module 200, so as to increase the screen ratio of the display module 200. Alternatively, the thickness of the mounting seat 311 in the optical axis direction Z and the aperture of the light-transmitting hole 3111 may not only be limited to the above values, but both may be adaptively adjusted according to the design requirements of the image capturing mechanism 300.

The lens assembly 312 may be provided with a single piece or multiple pieces of optical lenses, and the optical lenses may be made of plastic or glass, and the surface of the optical lenses may be spherical or aspherical. The lens assembly 312 may include at least one aspheric optical lens made of plastic, and the thickness and diameter of the optical lens may have a larger ratio. For example, the thickness of the optical lens may be 0.9mm, the diameter may be 1.4mm, and the ratio of the thickness to the diameter may be 0.9/1.4=0.64, which is advantageous for the optical lens to be disposed in the light-transmitting hole 3111. Optionally, the size of the optical lens may be adaptively adjusted according to the design requirement of the image capturing mechanism 300 and the space size of the light-transmitting hole 3111.

Referring to fig. 6 to 8 in conjunction with fig. 5, fig. 6 is a schematic diagram illustrating a connection structure of the lens module 320 and the photosensitive module 330 in fig. 4, fig. 7 is an exploded structure of the lens module 320 in fig. 6, and fig. 8 is a schematic diagram illustrating a cross-sectional structure of the lens module 320 and the photosensitive module 330 along vi-vi in fig. 6.

The lens module 320 may be connected to a side of the mounting base 311 facing away from the light-transmitting region 102, which may be used to implement a zoom function of the camera mechanism 300. As shown in fig. 6 to 8, the lens module 320 may include: a carrier 321, a zoom unit 322, a conductive member 323, and a lens unit 324. The carrier 321 may be connected to a side of the mounting seat 311 away from the light-transmitting area 102, the zoom unit 322 may be disposed on the carrier 321, and the zoom unit 322 may be mechanically deformed to change a path of light passing through the zoom unit 322, so as to implement a zoom function of the image capturing mechanism 300. The conductive member 323 can be embedded in the carrier 321, and can be respectively connected with the zoom unit 322 and the photosensitive module 330, and electrically connect the zoom unit 322 and the photosensitive module 330. The lens unit 324 may also be disposed on the carrier 321, and the lens unit 324 may also be disposed opposite the zoom unit 322 in the optical axis direction Z.

The carrier 321 may be connected to the mount 311, which may be used to carry a zoom unit 322 and a lens unit 324. As shown in fig. 6 to 8, the carrier 321 may include: a fixed seat 3211 and a sleeve 3212. Wherein, the fixing base 3211 may be connected with the photosensitive module 330, and the fixing base 3211 may be used to mount the zoom unit 322 and the lens unit 324. The sleeve 3212 may be sleeved on the fixing base 3211, and the sleeve 3212 may be connected to the mounting base 311, which may be used to mount the conductive member 323. In this way, by separately disposing the conductive member 323 on the sleeve 3212, the independence of the zoom unit 322 and the lens unit 324 is improved, and the conductive member 323 is prevented from affecting the mounting accuracy of the zoom unit 322 and the lens unit 324 on the fixing base 3211.

Specifically, the fixing base 3211 may include a main body portion 32111 and a protrusion 32112 of an integral structure. Wherein, the main body portion 32111 may be connected to the photosensitive module 330, the protruding portion 32112 may be located on a side of the main body portion 32111 facing away from the photosensitive module 330, and the protruding portion 32112 may be connected to a side of the mounting base 311 facing away from the light-transmitting region 102. For example, the protrusion 32112 and the mount 311 may be fixed by using adhesive to assemble the lens module 310 and the lens module 320. Meanwhile, the fixing base 3211 may be provided with a mounting hole 3001 opened in the optical axis direction Z, and the mounting hole 3001 may penetrate the main body portion 32111 and the protrusion 32112, which may be used to mount the lens unit 324. The side of the protrusion 32112 facing away from the main body portion 32111 may be provided with a mounting groove 3002 communicating with the mounting hole 3001, and the mounting groove 3002 may be disposed opposite to the light-transmitting hole 3111, which may be used to mount the zoom unit 322. In addition, in order to facilitate the electrical connection between the conductive member 323 and the zoom unit 322, a side of the protruding portion 32112 away from the main body portion 32111 may further be provided with a avoiding groove 3003 communicating with the mounting groove 3002, where the avoiding groove 3003 is used to provide a avoiding space for the electrical connection between the conductive member 323 and the zoom unit 322.

The sleeve 3212 may be connected to a side of the main body portion 32111 facing away from the photosensitive module 330, and the two may be fixed by glue, and the sleeve 3212 may be sleeved on the protrusion 32112. As shown in fig. 6 and 8, the sleeve 3212 may include: a base 32121, a first boss 32122, and a second boss 32123. The base 32121 may be located on a side of the main body portion 32111 facing away from the photosensitive module 330, and connected to the main body portion 32111 through adhesive. The first boss 32122 may be disposed on a side of the base 32121 facing away from the main body portion 32111, and the first boss 32122 may be disposed adjacent to the protrusion portion 32112. The second boss 32123 may be disposed on a side of the base 32121 facing away from the first boss 32122, and the second boss 32123 is further disposed on a side of the main body 32111 parallel to the optical axis direction Z, that is, an orthographic projection of the second boss 32123 in the optical axis direction Z does not overlap with an orthographic projection of the main body 32111 in the optical axis direction Z. Meanwhile, the first boss 32122 and the second boss 32123 may be used to draw out both ends of the conductive member 323 so that the conductive member 323 is electrically connected with the zoom unit 322 and the photosensitive module 330, respectively. Alternatively, the design of the first boss 32122 and/or the second boss 32123 may be omitted.

Referring to fig. 9, fig. 9 is a schematic cross-sectional structure of the zoom unit 322 of fig. 8.

The zoom unit 322 may be disposed in the mounting groove 3002, and the zoom unit 322 may be a liquid lens, which may have a light transmittance of at least 95% or more, and may be mechanically deformed to change its curvature after being energized, so that a propagation path of incident light may be changed, thereby implementing a focusing function of the image capturing mechanism 300. As shown in fig. 9, the zoom unit 322 may be provided with a housing 3221 and an elastic transparent body 3222. The outer case 3221 may be provided with a top plate a, a side plate B, and a bottom plate C, among others. The top plate A is connected with the side plate B, and the bottom plate C is arranged opposite to the top plate A and forms a containing space D. Alternatively, the top plate a and the side plate B may be integrally formed of the same material, such as glass or silicon. The side plate B may be adhesively fixed to the protrusion 32112. For example, at least two areas on the inner wall of the mounting groove 3002 may be dispensed, and the glue may have at least two different elastic moduli, such as an elastic modulus within 100 and an elastic modulus within 25. Meanwhile, after the zoom unit 322 is placed in the mounting groove 3002, the glue may be cured by at least two different curing methods, such as uv curing and heat curing, so as to bond the side plate B and the protrusion 32112 quickly. The top plate a may be covered with a layer of piezoelectric ceramic, and electrodes for electrical connection with the conductive members 323 may be further disposed on the piezoelectric ceramic, so that the piezoelectric ceramic may be deformed under the driving of voltage. The thickness of the top plate a is generally small. In this embodiment, the middle position of the top plate a may be a circular transparent lens, or a light-transmitting region without piezoelectric ceramic is used as the light-entering hole of the zoom unit 322.

The elastic transparent body 3222 may be disposed in the accommodating space D between the bottom plate C and the top plate a, and two opposite sides of the elastic transparent body 3222 are respectively connected with the bottom plate C and the top plate a. The elastic transparent body 3222 may be made of flexible resin or silica gel, and two opposite sides of the elastic transparent body 3222 are respectively adhered and fixed to the bottom plate C and the top plate a. In this way, when the relative position between the bottom plate C and the top plate a changes (for example, when the piezoelectric ceramic on the top plate a changes under the action of a voltage), the opposite side surfaces of the elastic transparent body 3222 are respectively bonded and fixed to the bottom plate C and the top plate a, so that the elastic transparent body 3222 can change with the deformation of the top plate a. Meanwhile, since the elastic transparent body 3222 may be equivalent to a transparent lens, when the elastic transparent body 3222 is deformed, the curvature or the shape of the elastic transparent body 3222 is changed, so that the propagation path of the incident light in the zoom unit 322 is changed, and the focusing purpose of the image capturing mechanism 300 is achieved.

In some embodiments, the zoom unit 322 may also be disposed in the mounting hole 3001, i.e., the zoom unit 322 may not be limited to be disposed on the side of the protrusion 32112 near the mounting seat 311, and its layout position may also be adaptively adjusted according to the design requirement of the camera mechanism 300. Meanwhile, the number of the zoom units 322 may be not limited to one, but may be plural, such as two, three, or four. Further, in some embodiments, the zoom unit 322 may also change the propagation path of the incident light only after power-on without mechanical deformation. For example, the zoom unit 322 may be a liquid crystal lens, and when the zoom unit 322 is powered on, it may deflect the liquid crystal to change the propagation path of the light, so as to implement the focusing function of the image capturing mechanism 300.

Referring to fig. 10 to 11 in conjunction with fig. 6, fig. 10 is a partially enlarged view of fig. 6 at E, and fig. 11 is a partially enlarged view of fig. 6 at F.

The conductive member 323 can be made of a conductive material such as metal, and the conductive member 323 can be embedded in the sleeve 3212, and the conductive member 323 and the sleeve 3212 can be integrally formed by an in-mold injection molding process, so as to reduce the production cost and the manufacturing difficulty of the lens module 320. As shown in fig. 6 and 10 to 11, the number of the conductive members 323 may be two, and the two conductive members 323 may be connected to the positive and negative electrodes of the zoom unit 322, respectively, and only a single conductive member 323 is exemplified below. One end of the conductive member 323 electrically connected to the zoom unit 322 may extend from the first boss 32122 into the base 32121, and one end of the conductive member 323 may be further disposed in the escape groove 3003. The other end of the conductive member 323 electrically connected to the photosensitive module 330 may extend from the second boss 32123 into the base 32121. Thus, the conductive piece 323 can be utilized to realize the electrical conduction between the zoom unit 322 and the photosensitive module 330, and the sleeve 3212 and the conductive piece 323 are integrally formed by adopting a relatively mature in-mold injection molding process, so that the combination reliability of the sleeve 3212 and the conductive piece 323 can be improved, and the production cost and the manufacturing difficulty of the lens module 320 can be reduced. In addition, the description of "embedded in" in this embodiment is a generalized description of the structure of the conductive member 323 after being integrally formed with the sleeve 3212 by using an in-mold injection molding process, which may be essentially understood as directly being that the conductive member 323 is integrally formed with the sleeve 3212 by using an in-mold injection molding process.

Further, since the conductive member 323 is integrally formed with the sleeve 3212 by in-mold molding, it cannot directly contact the zoom unit 322 to achieve electrical connection during molding, and thus the lens module 320 may be further provided with a lead 325 to achieve electrical connection between the conductive member 323 and the zoom unit 322. As shown in fig. 10, one end of the lead 325 may be connected to a side of the zoom unit 322 near the lens module 310, that is, to the piezoelectric ceramic on the top plate a, and the other end may be connected to an end of the conductive member 323 located in the escape groove 3003. The wire 325 may be formed by a wire bonding process, and the wire 325 has a diameter of at least 0.8mil, 0.9mil, or 1.0mil, etc. to electrically connect the zoom unit 322 and the conductive member 323.

Accordingly, due to the need of the gold wire bonding process, the end of the conductive member 323 located in the escape groove 3003 may be further provided with a metal plating layer 3231, and the metal plating layer 3231 may contain nickel, palladium, gold elements. The other end of the lead 325 may be bonded to the conductive member 323 by a metal plating layer 3231. Wherein the length L1 of the metal plating layer 3231 in the first direction X may be greater than or equal to 0.5mm, specifically, such as 0.5mm, 0.6mm, or 0.7mm. Meanwhile, the width W1 of the metal plating layer 3231 in the second direction Y may be greater than or equal to 0.6mm, specifically, 0.6mm, 0.7mm, or 0.8mm. In the present embodiment, the metal plating layer 3231 may entirely cover one end of the conductive member 323 located in the escape groove 3003, and the first direction X and the second direction Y may be perpendicular, and both may also be perpendicular to the optical axis direction Z.

Alternatively, one end of the conductive member 323 may be adaptively adjusted according to the position of the zoom unit 322. For example, when the zoom unit 322 is disposed in the mounting hole 3001, one end of the conductive member 323 may protrude from a side of the sleeve 3212 near the protrusion 32112 and extend through the protrusion 32112 into the mounting hole 3001 to be electrically connected with the zoom unit 322 in the mounting hole 3001. Optionally, the conductive member 323 can also be embedded in the fixing base 3211, and the design of the sleeve 3212 can be omitted to reduce the weight and production cost of the lens module 320.
