In this embodiment, the transparent cover plate, the touch panel and the display panel may be attached together by using an optical Adhesive (OCA) or a Pressure Sensitive Adhesive (PSA).

The housing 200 may be used to mount various electronic devices required by the electronic apparatus 10, and the housing 200 may surround the display screen 100 to form the mounting space 101. As shown in fig. 2, the case 200 may include: a middle frame 210 and a rear case 220. The display screen 100 may cover one side of the middle frame 210, and the rear case 220 may cover the other opposite side of the middle frame 210, and the three may together enclose the installation space 101. The installation space 101 may be divided into a first installation space 1011 defined by the display screen 100 and the middle frame 210, and a second installation space 1012 defined by the middle frame 210 and the rear case 220. Meanwhile, the first installation space 1011 can be used for installing electronic devices such as a fingerprint identification sensor, a distance sensor and an infrared sensor, so as to realize functions such as fingerprint unlocking, automatic screen turning-off, brightness self-adjustment and the like.

The material of the middle frame 210 and the rear case 220 may be glass, metal, hard plastic, etc., so that the middle frame 210 and the rear case 220 have certain structural strength. In addition, since the middle frame 210 and the rear housing 220 are generally directly exposed to the external environment, the middle frame 210 and the rear housing 220 may also have certain wear-resistant, corrosion-resistant, scratch-resistant, and other properties, or the outer surfaces of the middle frame 210 and the rear housing 220 (i.e., the outer surfaces of the electronic device 10) may be coated with a layer of functional material for wear-resistant, corrosion-resistant, scratch-resistant. Optionally, a film such as a texture, a gradient color, a photochromic film, an electrochromic film, and the like may be further designed on the rear shell 220 to enhance the appearance of the electronic device 10.

The camera 300 may be disposed in the installation space 101, and the camera 300 may receive external light to form an image. The imaging mechanism 300 may be provided in the first installation space 1011 to perform front-end imaging, or may be provided in the second installation space 1012 to perform rear-end imaging. Of course, the first installation space 1011 and the second installation space 1012 may be provided with the imaging mechanism 300 at the same time. It is understood that the front camera means that the camera 300 receives light from the side of the display screen 100 for imaging, and the rear camera means that the camera 300 receives light from the side of the rear housing 220 for imaging.

As shown in fig. 2, when the camera 300 is disposed in the first installation space 1011, the area of the display screen 100 corresponding to the camera 300 may be provided with a first transparent area 110, so that light reflected by an external object can be irradiated to the camera 300 through the first transparent area 110, so as to facilitate the camera 300 to form an image. Accordingly, when the camera mechanism 300 is disposed in the second installation space 1012, the region of the rear housing 220 corresponding to the camera mechanism 300 may also be provided with the second light-transmitting region 221, so that light reflected by an external object can be irradiated to the camera mechanism 300 through the second light-transmitting region 221, so as to facilitate imaging performed by the camera mechanism 300. The first light-transmitting area 110 and the second light-transmitting area 221 may be light-transmitting holes, that is, corresponding holes are formed in the display screen 100 and the rear case 220 for transmitting light. Alternatively, the display screen 100 and the rear case 220 may be partially transparent to form the first transparent region 110 and the second transparent region 221, and only the external light can be irradiated to the camera mechanism 300 through the first transparent region 110 and the second transparent region 221.

Referring to fig. 3 to 5, fig. 3 is a schematic structural diagram of the camera 300 in fig. 2, fig. 4 is a schematic structural diagram of a partial cross section of the camera 300 along v-v in fig. 3, and fig. 5 is a schematic structural diagram of a cross section of the anti-shake module 310 in fig. 4.

The camera shooting mechanism 300 can have an anti-shake function, and the power consumption in the using process is low, so that the shooting effect of the camera shooting mechanism 300 can be improved, and the service life of the camera shooting mechanism 300 can be prolonged. As shown in fig. 3 to 4, the image pickup mechanism 300 may include: an anti-shake module 310, a photosensitive module 320, and a frame 330. Wherein, the anti-shake module 310 can be set up with the sensitization module 320 relatively, and the sensitization module 320 can be located the light-emitting path of anti-shake module 310, and it can be used for receiving the light that jets out from anti-shake module 310 and form images. The frame 330 can accommodate the anti-shake module 310 and the photosensitive module 320 to keep the tightness of the camera mechanism 300, and reduce the influence of the external environment on the anti-shake module 310 and the photosensitive module 320. In this embodiment, the anti-shake module 310 may compensate for shake of the camera 300 during shooting, so as to realize an anti-shake function of the camera 300. Meanwhile, the anti-shake module 310 has low power consumption in the using process, which is beneficial for the user to use the camera mechanism 300 for a long time. Optionally, besides the anti-shake module 310 and the photosensitive module 320, the camera shooting mechanism 300 may further be provided with other modules with different functions, so as to improve the shooting effect of the camera shooting mechanism 300, which is not limited in this embodiment.

As shown in fig. 4 to 5, the anti-shake module 310 may include: mount 311, first drive assembly 312, second drive assembly 313, and lens assembly 314. The mounting base 311 may be connected to the first driving assembly 312 and the second driving assembly 313, respectively, and the mounting base 311 may further rotate in the first direction Y as an axis direction under the driving of the first driving assembly 312. Lens assembly 314 may be connected to second driving assembly 313, and may rotate around second direction X as an axis direction under the driving of second driving assembly 313. With such an arrangement, lens assembly 314 can be driven by mounting base 311 to rotate along the axis in the first direction Y, and can also be driven by second driving assembly 313 to rotate along the axis in the second direction X, so that lens assembly 314 can compensate for the shake of camera mechanism 300 during the shooting process, thereby achieving the anti-shake function of camera mechanism 300. In this embodiment, the first driving assembly 312 and the second driving assembly 313 may be the same driving assembly, and both can realize motion control with high precision and large stroke, and keep low power consumption, which not only can improve the anti-shake effect of the anti-shake module 310, but also is beneficial to the user to use the camera mechanism 300 for a long time.

It is understood that the first direction Y and the second direction X may be two intersecting directions, so that the lens assembly 314 can rotate in multiple dimensions to improve the anti-shake effect of the camera mechanism 300. Preferably, the first direction Y and the second direction X may be perpendicular.

Alternatively, the second driving component 313 may be omitted, that is, the anti-shake module 310 may also be provided with only the first driving component 312, and the lens component 314 may be directly disposed on the mounting base 311 and may rotate around the first direction Y as an axis direction only under the driving of the mounting base 311. In this way, the first driving assembly 312 can still drive the lens assembly 314 to rotate around the first direction Y as an axis direction, so as to realize the anti-shake function of the imaging mechanism 300.

Mount 311 may be used to rotate lens assembly 314 about a first direction Y. As shown in fig. 4 to 5, the mounting seat 311 may be disposed in the frame 330, and the mounting seat 311 may have a first receiving portion 3111 and a second receiving portion 3112 connected and vertically disposed. Here, the first receiving portion 3111 may have a first surface 3001 perpendicular to the first direction Y, the second receiving portion 3112 may have a second surface 3002 perpendicular to the second direction, and the first surface 3001 and the second surface 3002 may be connected. Meanwhile, the first bearing portion 3111 may be connected with the first driving assembly 312, and the first driving assembly 312 may be located at a side of the first bearing portion 3111 facing away from the first surface 3001. The second bearing portion 3112 may be connected to the second driving assembly 313, and the second driving assembly 313 may be located at a side where the second surface 3002 is located.

Referring to fig. 6 to 9 in conjunction with fig. 4 to 5, fig. 6 is a partially enlarged schematic view of a portion a in fig. 4, fig. 7 is another sectional structure schematic view of the first driving assembly 312 in fig. 6, fig. 8 is a structural schematic view of the transmission portion 31244 in fig. 7, and fig. 9 is a partially enlarged schematic view of a portion B in fig. 4.

Through long-term research by the inventor, the accuracy and the stroke of the traditional electromagnetic motor are greatly limited by ADC/DAC (analog-to-digital conversion/digital-to-analog conversion), and the motion control with high accuracy and large stroke is difficult to realize simultaneously. Generally, the larger the stroke of the electromagnetic motor, the larger the corresponding drive current, and the higher the current accuracy, the higher the minimum drive accuracy. For example, if the movement stroke of the electromagnetic motor is 1mm, the maximum current corresponds to 1000mA, and the minimum precision corresponds to 1um, a 10-bit drive IC is required for control. When the motion stroke is correspondingly expanded to 2mm and 3mm, and the minimum precision is not changed, the maximum current needs to be correspondingly expanded to 2000mA and 3000mA, and 11bit and 12bit drive ICs are needed. Thus, when it is necessary to simultaneously control a motion with high precision and a large stroke, the power consumption of the electromagnetic motor increases, and the cost and the size of the driving IC also increase.

In order to solve the foregoing technical problem, each of the first driving assembly 312 and the second driving assembly 313 in the embodiment of the present application may be a piezoelectric driving structure, so as to utilize the characteristics of piezoelectric driving, so that the first driving assembly 312 and the second driving assembly 313 can simultaneously achieve motion control with high precision and large stroke, and reduce power consumption of themselves. Specifically, the first driving component 312 and the second driving component 313 may be resonant piezoelectric modules, and the principle thereof is roughly as follows: first drive assembly 312 and second drive assembly 313 can move elliptically with a sinusoidal drive that moves lens assembly 314 accordingly. Because the displacement of each elliptic motion is extremely small and only nano-scale motion is realized, the submicron-scale control precision can be easily realized by adjusting the periodicity of the sine wave control signal. Meanwhile, as the movement stroke is only related to the periodicity of the sine wave control signal, when long-stroke movement needs to be realized, the maximum current does not need to be increased, and the power consumption can be effectively reduced.

The specific structure of the first driving assembly 312 and the second driving assembly 313 will be further described below. The first driving assembly 312 may be used to drive the mounting base 311 to rotate in the first direction Y-axis direction. As shown in fig. 4 to 6, the first driving assembly 312 may include: the first fixing member 3121, the first moving member 3122, the first rotating shaft 3123, the first driving member 3124, and the first adjusting member 3125. Wherein, the first fixed member 3121 may be opposite to and spaced apart from the first movable member 3122. The first rotating shaft 3123 is disposed through the first fixing member 3121 and the first moving member 3122, and the first rotating shaft 3123 may be disposed in parallel with the first direction Y. The first driving member 3124 is located between the first fixing member 3121 and the first moving member 3122, and is abutted against the first fixing member 3121 and the first moving member 3122, and the first driving member 3124 may generate a slight vibration after being energized to drive the first moving member 3122 to rotate relative to the first rotating shaft 3123. The first adjusting member 3125 may be provided on the first rotating shaft 3123 and may be displaced with respect to the first rotating shaft 3123 to adjust an abutting force between the first moving member 3122 and the first driving member 3124.

Further, a side of the first fixing member 3121 facing away from the first moving member 3122 may be connected with the frame 330 to fix the first driving assembly 312 within the frame 330. One side of the first moving member 3122 facing away from the first fixing member 3121 may be connected to one side of the first bearing portion 3111 facing away from the first surface 3001, so that the first moving member 3122 may drive the lens assembly 314 to rotate by taking the first direction Y as an axial direction through the mounting seat 311. The first fixing member 3121 and the frame 330, and the first moving member 3122 and the first receiving portion 3111 can be fixedly connected by means of, for example, adhesion, welding, and bolt connection.

The first rotating shaft 3123 may be disposed in parallel with the first direction Y, and one end thereof may be fixedly connected to the first fixing member 3121 and the other end thereof may rotate relative to the first moving member 3122. For example, a bearing 3003 may be provided between the first moving member 3122 and the first rotating shaft 3123 to enable relative rotation of the first moving member 3122 and the first rotating shaft 3123.

The first driving member 3124 can generate a slight vibration after being powered on, so as to drive the first moving member 3122 to rotate relative to the first rotating shaft 3123, and further drive the first bearing portion 3111 to rotate in the first direction Y. As shown in fig. 6, the first driving member 3124 may include: a vibrating portion 31241, a friction portion 31242, and an elastic portion 31243. In which the vibration portion 31241 may be located at a side of the first fixing member 3121 facing the first moving member 3122, and the vibration portion 31241 may vibrate slightly when it is powered on. The friction portion 31242 may be located at a side of the vibration portion 31241 facing the first moving member 3122. The elastic portion 31243 may be located at a side of the vibration portion 31241 facing the first fixing piece 3121, and the elastic portion 31243 may be abutted against the first fixing piece 3121 and the vibration portion 31241, respectively, to provide elastic force to indirectly act on the friction portion 31242, so that the friction portion 31242 may be abutted against the vibration portion 31241 and the first moving piece 3122, respectively, by the elastic force. With this arrangement, when the vibrating portion 31241 is energized to generate vibration, the friction portion 31242 in close contact with the vibrating portion 31241 can drive the first moving element 3122 to rotate relative to the first rotating shaft 3123 under the driving of the vibrating portion 31241.

Specifically, the vibrating portion 31241 may be provided in a circular ring shape, and surround the first rotation shaft 3123. Meanwhile, the vibrating portion 31241 may be made of a piezoelectric material such as a piezoelectric ceramic or a piezoelectric single crystal, which may be a single layer ceramic or a multilayer ceramic. For example, the vibrating portion 31241 may be made of a material such as a lead zirconate titanate-based piezoelectric ceramic, a potassium sodium niobate-based piezoelectric ceramic, a barium titanate-based piezoelectric ceramic, a lead magnesium niobate-lead indium niobate-based piezoelectric single crystal, or a textured ceramic. Meanwhile, an electrode and a contact for electrical connection may be further provided on an outer surface of the vibration portion 31241, so that an external circuit applies a control signal to the vibration portion 31241. In this way, when the vibrating portion 31241 receives a high-frequency alternating current signal greater than 20kHz, the vibrating portion 31241 can simultaneously excite multiple modes, and the multiple-mode coupling generates a micro-amplitude vibration and a driving force, and the friction portion 31242 and the first moving member 3122 are tightly fitted through the elastic portion 31243, so that the micro-amplitude vibration of the vibrating portion 31241 is converted into a rotation of the first moving member 3122, thereby implementing a rotation of the first moving member 3122 about the first direction Y. The specific operation principle of the vibrating portion 31241 can refer to the inverse piezoelectric effect in the prior art, which is not described herein in detail.

The friction portion 31242 may be provided at a side of the vibration portion 31241 facing the first moving member 3122, and the shape of the friction portion 31242 may match the shape of the vibration portion 31241, that is, the friction portion 31242 may also have a circular ring shape and be provided around the first rotation shaft 3123. Meanwhile, the friction portion 31242 may be made of a wear-resistant material such as alumina, silica, zirconia, carbon fiber, or polyester fiber to improve the lifespan of the friction portion 31242 and maintain the fitting accuracy of the first driving member 3124 and the first moving member 3122. The elastic portion 31243 may be disposed between the first fixing piece 3121 and the vibration portion 31241, which may provide an elastic force acting on the vibration portion 31241 so that the friction portion 31242 can be abutted against the first moving member 3122, improving the fitting tightness of the friction portion 31242 and the first moving member 3122. The elastic portion 31243 may be a spring or a leaf spring, or an elastic pad made of elastic materials such as rubber, silicone, and soft plastic.

Optionally, in order to amplify the motion trace of the vibration portion 31241 and increase the driving speed of the vibration portion 31241, the first driving member 3124 may be further provided with a transmission portion 31244. As shown in fig. 7 to 8, the transmission portion 31244 may be located between the vibration portion 31241 and the friction portion 31242, and the transmission portion 31244 may be in contact with the vibration portion 31241 and the friction portion 31242, respectively, or may be in a shape adapted to the vibration portion 31241, that is, in an annular shape. Here, a side of the transmission portion 31244 facing the friction portion 31242 may be provided with a plurality of protrusions 312441 spaced apart from each other to abut against the friction portion 31242, and the plurality of protrusions 312441 may be arranged in a ring shape and be disposed around the first rotation shaft 3123. In this way, when the driving force of the vibrating portion 31241 is transmitted to the transmission portion 31244, the transmission portion 31244 may rub against the friction portion 31242 by the plurality of protrusions 312441, so as to reduce the loss of the friction transmission between the transmission portion 31244 and the friction portion 31242 by reducing the contact area, thereby amplifying the motion trajectory of the vibrating portion 31241 and increasing the driving speed of the vibrating portion 31241.

As shown in fig. 6, the first adjusting member 3125 may be disposed on the first rotating shaft 3123, and the first adjusting member 3125 may be located at a side of the first moving member 3122 facing away from the first fixing member 3121. Wherein the first adjusting member 3125 is displaceable in a direction toward or away from the first moving member 3122 with respect to the first rotation shaft 3123 to adjust the abutting force between the first moving member 3122 and the friction portion 31242. For example, a screw thread may be disposed on the first rotating shaft 3123, the first adjusting member 3125 may be sleeved on the first rotating shaft 3123, and the first adjusting member 3125 may also be provided with a screw thread corresponding to the first rotating shaft 3123, so that the first adjusting member 3125 can be displaced on the first rotating shaft 3123 by the screw thread. In this way, when it is necessary to increase the abutting force between the first moving member 3122 and the friction portion 31242, the first adjusting member 3125 can be displaced in a direction to approach the first moving member 3122 by rotating the first adjusting member 3125 so as to abut against the first moving member 3122. When it is necessary to reduce the abutting force between the first movement member 3122 and the friction portion 31242, the first adjustment member 3125 and the first movement member 3122 may be released by rotating the first adjustment member 3125 to be displaced in a direction away from the first movement member 3122. Alternatively, first trim 3125 may be omitted and the abutment force between first moving member 3122 and friction portion 31242 may remain fixed.

Second drive assembly 313 may be configured the same as first drive assembly 312, and may be configured to drive lens assembly 314 to rotate about second direction X. As shown in fig. 9, the second driving assembly 313 may include: a second fixed element 3131, a second moving element 3132, a second rotating shaft 3133, a second driving element 3134, and a second adjusting element 3135. The second fixing element 3131 may be disposed opposite to the second moving element 3132 at an interval. The second rotation shaft 3133 penetrates through the second fixed element 3131 and the second moving element 3132, and the second rotation shaft 3133 may be parallel to the second direction X. Second driving element 3134 is located between second fixed element 3131 and second moving element 3132, and is abutted against second fixed element 3131 and second moving element 3132, and second driving element 3134 can generate a slight vibration after being powered on, so as to drive second moving element 3132 to rotate relative to second rotating shaft 3133. The second adjusting element 3135 can be disposed on the second rotating shaft 3133 and can be displaced relative to the second rotating shaft 3133 to adjust the abutting force between the second moving element 3132 and the second driving element 3134.

Further, a second fixing part 3131 may be disposed on the second surface 3002 of the second bearing portion 3112 to fix the second driving assembly 313 on the mounting seat 311. A side of second moving element 3132 facing away from second fixing element 3131 may be connected to lens assembly 314, such that second moving element 3132 drives lens assembly 314 to rotate along second direction X. The second fixing element 3131 and the second bearing portion 3112, and the second moving element 3132 and the lens assembly 314 may be fixedly connected by bonding, welding, and bolting, for example.

The second rotation shaft 3133 may be disposed parallel to the second direction X, and one end of the second rotation shaft 3133 may be fixedly connected to the second fixing element 3131, and the other end of the second rotation shaft may rotate relative to the second moving element 3132. For example, a bearing 3003 may be disposed between the second mover 3132 and the second rotation shaft 3133 to enable relative rotation of the second mover 3132 and the second rotation shaft 3133. Second driving element 3134 can vibrate slightly after being powered on, so as to drive second moving element 3132 to rotate relative to second rotating shaft 3133, and further drive lens assembly 314 to rotate around second direction X. The structure and operation principle of the second driving element 3134 may be the same as those of the first driving element 3124, and details of this embodiment are not repeated herein.

As shown in fig. 9, the second adjusting element 3135 may be disposed on the second rotating shaft 3133, and the second adjusting element 3135 may be located on a side of the second moving element 3132 away from the second fixed element 3131. Wherein the second adjusting part 3135 is displaceable with respect to the second rotation shaft 3133 in a direction toward or away from the second moving part 3132 to adjust an abutting force between the second moving part 3132 and the friction portion 31242. For example, the second rotation shaft 3133 may have a screw thread, the second adjusting element 3135 may be sleeved on the second rotation shaft 3133, and the second adjusting element 3135 may also have a screw thread corresponding to the second rotation shaft 3133, such that the second adjusting element 3135 may be displaced on the second rotation shaft 3133 by the screw thread. In this way, when it is necessary to increase the abutting force between second moving element 3132 and friction portion 31242, second adjusting element 3135 may be moved toward second moving element 3132 by rotating second adjusting element 3135, such that second adjusting element 3135 abuts against second moving element 3132. When it is desired to reduce the abutting force between second mover 3132 and friction portion 31242, second adjuster 3135 may be released from second mover 3132 by rotating second adjuster 3135 to displace in a direction away from second mover 3132. Alternatively, second adjusting member 3135 may also be omitted, and the abutment force between second moving member 3132 and friction portion 31242 may remain fixed.

As shown in FIG. 5, lens assembly 314 may include: a carrier 3141 and a lens 3142. The carrier 3141 can be connected to the second moving element 3132 and can be driven by the second moving element 3132 to rotate around the second direction X. For example, the carrier 3141 and the second mover 3132 may be fixedly coupled by means of bonding, welding, bolting, etc. The lens 3142 may be disposed on the carrier 3141, and the lens 3142 may be a prism, which may be used to change a transmission path of light to achieve the purpose of extending a light path, and at this time, the image capturing mechanism 300 may be designed in a corresponding periscopic manner, which is beneficial to achieve multiple times of optical zooming of the image capturing mechanism 300.

The light rays can be incident from the light incident surface 31421, and then are emitted from the light emitting surface 31422 after being reflected by the reflecting surface 31423, so that the conduction path of the light rays is changed, and the light path of the light rays is prolonged. Alternatively, the lens 3142 may be a conventional concave-convex lens for converging or diverging light. For example, the lens 3142 may have a single piece or a plurality of pieces of optical lenses made of glass or transparent plastic, such as a free-form surface lens, a spherical lens, an aspherical lens, and the like, and the plurality of pieces of optical lenses may mutually correct and filter light and eliminate aberration.

As shown in fig. 4, the photosensitive module 320 may be disposed opposite to the light emitting surface 31422 of the lens module 3142, and may be configured to receive the light emitted from the light emitting surface 31422 of the lens 3142 for imaging. For example, the photosensitive module 320 may include: a light sensor 321, a circuit board 322, a filter 323, and a mounting block 324. The optical sensor 321 may be disposed on the circuit board 322 and opposite to the light emitting surface 31422. The mounting block 324 may cover the light sensor 321, and the optical filter 323 may be disposed on the mounting block 324 and opposite to the light sensor 321, and may filter stray light emitted from the light emitting surface 31422, so as to improve an imaging effect of the camera mechanism 300. Specifically, the optical sensor 321 may be a sensor such as a CCD (Charge Coupled Device) or a sensor such as a CMOS (Complementary Metal Oxide Semiconductor). For image sensors such as CMOS, RGGB can be used as a basis, and RYYB can be used as a basis.

The frame 330 may be used to accommodate the anti-shake module 310 and the photosensitive module 320, so as to prevent the external environment from affecting the anti-shake module 310 and the photosensitive module 320. The region of the frame 330 opposite to the light incident surface 31421 may be provided with a notch or be partially transparent for transmitting light, so that the light can be incident into the lens 3142 for transmission. Alternatively, the image capturing mechanism 300 may only include the anti-shake module 310 and the photosensitive module 320, and the frame 330 may be omitted, in which case the anti-shake module 310 and the photosensitive module 320 may be directly mounted on the middle frame 210 or the rear case 220, or a structure similar to the frame 330 is provided on the middle frame 210 and the rear case 220 for accommodating the anti-shake module 310 and the photosensitive module 320.

Referring to fig. 10 to 12, fig. 10 is a schematic sectional view of another portion of the camera 300 along v-v in fig. 3, fig. 11 is a schematic sectional view of the focusing module 340 in fig. 10, and fig. 12 is a schematic sectional view of another portion of the camera 300 along vi-vi in fig. 3.

In order to further improve the shooting effect of the camera mechanism 300, the camera mechanism 300 may further be provided with a focusing module 340. As shown in fig. 10 to 11, the focusing module 340 may be located between the anti-shake module 310 and the photosensitive module 320, and the focusing module 340 may include: a piezoelectric motor 341, a mirror assembly 342, and a frame 343.

As shown in fig. 12, the piezoelectric motor 341 may include: piezoelectric body 3411, friction head 3412, and elastic member 3413. The piezoelectric body 3411 may be located between the lens assembly 342 and the frame 343, the friction head 3412 may be located on a side of the piezoelectric body 3411 facing the lens assembly 342, and the elastic body 3413 may be located between the piezoelectric body 3411 and the frame 343 and may be abutted against the piezoelectric body 3411 and the frame 343, respectively, so as to provide an elastic force to indirectly act on the friction head 3412, so that the friction head 3412 is abutted against the piezoelectric body 3411 and the lens assembly 342, respectively. Meanwhile, the piezoelectric body 3411 may vibrate slightly after being energized, so as to drive the friction head 3412 to drive the lens assembly 342 to move in a direction close to or away from the lens 3142, thereby implementing a focusing function of the camera mechanism 300. In this embodiment, the structure and operation principle of the piezoelectric motor 341 are the same as or similar to those of the first driving member 3124, and the description of this embodiment is omitted here.

Alternatively, the friction head 3412 may be disposed on a side of the piezoelectric body 3411 facing the frame 343, the elastic body 3413 may be disposed on a side of the piezoelectric body 3411 facing the lens assembly 342, and the friction head 3412 may be abutted against the frame 343 by an elastic force of the elastic body 3413. With this arrangement, when the piezoelectric body 3411 is energized, the generated vibration can act on the frame 343 through the friction head 3412, and since the frame 343 is fixed, the lens assembly 342 is driven by the piezoelectric body 3411 to displace accordingly.

The lens assembly 342 may be used to diverge or converge light and may be displaced by the piezoelectric motor 341. As shown in fig. 11 and 12, the lens assembly 342 may include: a carrier 3421 and a lens 3422. Here, the carrier 3421 may abut against the friction head 3412, and may be displaced in a direction to approach or separate from the lens 3142 by the driving of the friction head 3412. The lens 3422 may be disposed on the supporting member 3421 and disposed opposite to the lens 3142 and the light sensor 321 (i.e., the photosensitive module 340), respectively, and may be used for guiding the light emitted from the lens 3142 to the light sensor 321. The lens 3422 may include one or more optical lenses made of glass or transparent plastic, such as a free-form lens, a spherical lens, an aspheric lens, etc., and the optical lenses can correct and filter light and eliminate aberration.

The frame 343 may be configured to accommodate the piezoelectric motor 341 and the lens assembly 342, and in order to enable the light emitted from the lens 3142 to irradiate the lens 3422, openings 3431 may be further formed on two opposite sides of the frame 343 on the displacement path of the lens 3422, so that the light can irradiate the lens 3422 through the openings 3431. Alternatively, the frame 343 may be omitted, and the piezoelectric motor 341 and the lens assembly 342 may be disposed directly in the frame 330.

Further, in order to guide the displacement of the lens assembly 342, the focusing module 340 may be further provided with a sliding member 344. As shown in fig. 12, the slider 344 may be located between the carrier 3421 and the frame 343, and the slider 344 may be located on a side of the carrier 3421 facing away from the friction head 3412. Meanwhile, the carrier 3421 and the frame 343 may further clamp the sliding member 344, and the three components cooperate to form a guiding structure for guiding the displacement of the carrier 3421. For example, the frame 343 and the carrier 3421 may be provided with corresponding sliding grooves, and both may be provided with the sliding grooves to clamp the sliding member 344 together, so that the three cooperate to form a guiding structure. In this embodiment, the sliding member 344 may be a ball, which is beneficial to reduce friction between the carrier 3421 and the frame 343. Meanwhile, when facing a long distance displacement, the sliding member 344 may also be a roller, which is beneficial to improve the motion stability of the supporting member 3421. Furthermore, in order to reduce the jamming during the displacement of the carrier 3421, the slide groove may preferably be designed as a U-shaped groove or a V-shaped groove.

Meanwhile, by arranging the optical assembly 342 opposite to the lens assembly 314, and by driving the optical assembly 342 to move toward or away from the lens assembly 314 by the piezoelectric motor 341, the focusing function of the camera mechanism 300 can be realized. In addition, when the anti-shake and focusing functions of the camera mechanism 300 are realized, because the first driving member 3124 and the piezoelectric motor 341 are both piezoelectric driving structures, the characteristics of piezoelectric driving can be utilized to realize motion control with high precision and large stroke, improve the anti-shake and focusing effects of the camera mechanism 300, and reduce the power consumption of the camera mechanism 300.
