Periscope camera module

Abstract

A periscope camera module, comprising: an outer frame body (100); a carrier (200); a pre-pressing actuation assembly (300); and a support assembly (400). When the pre-pressing actuation assembly (300) is not energized, the distance from a friction action point between the pre-pressing actuation assembly (300) and a side wall of the carrier (200) to a support point of a first support portion (410) on the side wall of the carrier (200) is equal to the distance from said friction action point to a support point of a second support portion (420) on the side wall of the carrier (200). A lateral driving solution is used to solve the driving problem caused by increased lens specifications of existing periscope camera modules due to technological iteration. In addition, the first support portion (410), the second support portion (420) and the pre-pressing actuation assembly (300) are arranged on a same side of the carrier (200), and in a non-energized state, the distance from a friction head (311) of the pre-pressing actuation assembly (300) to the first support portion (410) is equal to the distance from the friction head (311) of the pre-pressing actuation assembly (300) to the second support portion (420), so that the carrier (200) is sufficiently supported on a side surface in frictional contact with the pre-pressing actuation assembly (300), and the stress is balanced, thereby further improving the moving stability of the carrier (200).

Description

Periscopic camera module TECHNICAL FIELD

[0001] The present application relates to a periscopic camera module, in particular to a periscopic camera module using a piezoelectric motor. BACKGROUND

[0002] With the improvement of living standards, users' requirements for the camera function of mobile terminal equipment are also increasing, among which the demand for telephoto is proposed, which requires clear shooting of distant scenes, such as long focusing distance and high focusing accuracy.

[0003] To achieve the above-mentioned telephoto function, the terminal equipment usually adopts a periscopic camera module, which uses a motor to drive the lens to move to realize the basic functions of focusing and zooming, and then obtains a clear image of a distant object. However, with the improvement of user demand, the parameters of the periscope lens are required to be iterated, and the size and weight of the lens are increasing, so the thrust and stroke requirements of the motor driving the lens movement are gradually increasing, and further demand for focusing accuracy is also proposed. Due to the increase of thrust requirement, the volume of the motor is also gradually increased, which hinders the realization of thinness in the iteration of periscopic camera module technology. The existing driving scheme adopts an electromagnetic motor, but it has the problems of short stroke, large volume and electromagnetic interference, which cannot meet the technical requirements of periscopic camera module in future mobile phone photography.

[0004] In addition, when a new driving method such as piezoelectric friction contact actuation is applied to periscopic or long-stroke camera modules, a new motor architecture is needed to prevent or reduce the risk of lens carrier deviation or separation from the light path caused by the motor, while avoiding the tilting or overturning of the carrier due to insufficient support or unbalanced force on its friction contact surface. In long-stroke movement, the tilting or overturning of the movable carrier carrying the lens due to unbalanced force may cause a gap or direct separation between the motor and the carrier, reducing the adverse effects on the focusing effect of the camera module and further improving the stability of the carrier movement. At the same time, the new motor architecture also needs to consider the adverse effects on the carrier motion state when designing, to avoid the tilting or jamming of the carrier during movement, which may cause the periscopic camera module to malfunction. On the other hand, in order to further meet the development trend of electronic equipment miniaturization, the height of the periscopic camera module needs to be limited during design, thereby improving the compactness and rationality of the overall structure of the periscopic camera module.

[0088] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0089] The concept, specific structure and generated technical effects of the present application will be described clearly and completely in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments, and other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative labor are within the scope of protection of the present application. In addition, all the coupling / connection relationships involved in the patent do not mean that the components are directly connected, but means that a better coupling structure can be formed by adding or reducing coupling accessories according to the specific implementation situation. The technical features in the present application can be combined interactively without conflict.

[0090] As shown in FIGS. 1-37, the periscopic camera module according to embodiments of the present application is illustrated, which includes an outer frame 100, a carrier 200, a pre-press actuating assembly 300, and a support assembly 400. The outer frame 100 has at least one light inlet and one light outlet for allowing light to enter and exit. The carrier 200 moves along an axial direction within the outer frame 100, which is consistent or parallel with the optical axis direction of the optical elements (such as lenses or mirrors) carried by the carrier 200. Referring to FIGS. 1, 2, 3, 4, and 36, the outer frame 100 includes a bottom entity extending along the optical axis direction and two side entities extending vertically upward from both sides of the bottom entity. The pre-press actuating assembly 300 is assembled on one side entity of the outer frame 100. The pre-press actuating assembly 300 abuts and drives the carrier 200 from the side to move the carrier 200 along the optical axis direction, thereby achieving the zoom and / or focusing functions of the periscopic camera module. The support assembly 400 is correspondingly assembled between the opposite faces of the outer frame 100 and the carrier 200, which provides more stable support for the carrier 200 to move along the optical axis direction. The support assembly 400 can also reduce the risk of deviation, tilt, or even jamming during the movement of the carrier 200.

[0091] The periscopic camera module according to embodiments of the present application further includes an optical assembly 500, which includes a fixed optical assembly and a moving optical assembly arranged along the light propagation path. The fixed optical assembly and the moving optical assembly each include at least one lens 520. The fixed optical assembly is arranged in the outer frame 100, and the moving optical assembly is arranged in the carrier 200. In some embodiments, as shown in FIGS. 1, 2, 3, 4, and 36, light enters through the opening on the light inlet side of the outer frame 100, sequentially passes through the fixed optical assembly and the moving optical assembly along the optical axis, and then exits through the opening on the light outlet side of the outer frame 100. Thus, the light inlet side of the outer frame 100 is the light inlet side, and the light outlet side of the outer frame 100 is the light outlet side.

[0092] In addition, the periscopic camera module further includes a photosensitive module (not shown) and a light turning module 510. The light turning module 510 changes the direction of the incident light and makes the turned light sequentially pass through the fixed optical assembly and the moving optical assembly, and finally converges to the photosensitive module. The photosensitive module receives the light and forms an image.

[0093] In specific examples of the present application, the light turning module 510 is mounted on the light inlet side of the outer frame 100, and the photosensitive module is assembled on the light outlet side of the outer frame 100.

[0094] The related art provides a periscope camera module, which includes an outer frame 100, a carrier 200, a driving assembly, a light turning module 510, a lens module (optical assembly 500), and a photosensitive module. The carrier 200 moves along the optical axis direction in the outer frame 100. The optical assembly 500 is arranged on the light-in side of the outer frame 100 and the carrier 200 on the optical axis. The photosensitive module is arranged on the light-out side of the outer frame 100, that is, the outer frame 100, the carrier 200, the light turning module 510, the lens module (optical assembly 500), and the photosensitive module are all arranged in the horizontal space where the optical axis is located. In the above structure, if the driving assembly is arranged on the optical axis in the length direction, the length of the periscope camera module will be greatly increased. At the same time, the driving assembly needs a large thrust, which will make it difficult to reduce the size of the driving assembly, thereby increasing the overall size of the periscope camera module. If the driving assembly is arranged on the top side or the bottom side of the carrier 200 in the height direction, the height of the periscope camera module will be increased, which is not conducive to improving the structural compactness of the periscope camera module and the electronic device.

[0095] It can be understood that the periscope camera module is arranged in the electronic device in a "lying" manner, for example, the light turning module 510, the lens module (i.e., the optical assembly 500), and the photosensitive module in the periscope camera module are arranged along the length direction or the width direction of the electronic device, so that the height (i.e., the thickness) of the electronic device can be increased due to the long length of the periscope camera module. In other words, the height (i.e., the thickness) of the electronic device is limited by the height of the periscope camera module, and is irrelevant to the length and the width of the periscope camera module.

[0096] The photosensitive module includes a photosensitive assembly and a filter assembly. The filter assembly is arranged between the optical assembly 500 and the photosensitive assembly and is located on the photosensitive path of the photosensitive assembly, and is used for filtering the light before entering the photosensitive assembly. The photosensitive assembly is arranged on the light-out side of the outer frame 100. The filter assembly includes a filter element and a filter element support. The filter element support is located between the filter element and the light-out side of the outer frame 100 or between the filter element and the carrier 200, so that the filter element is located on the photosensitive path. Specifically, the photosensitive assembly is implemented as a circuit board and a photosensitive chip and electronic elements mounted on the circuit board.

[0097] With the increasing demand of users for the module camera function, the volume of the driving motor is also increasing due to the long stroke and large thrust. At the same time, with the development of the thin and light electronic device, the height of the periscope camera module will still be an obstacle to reduce the height of the electronic device. Therefore, in the present application, the structure of the periscope camera module is designed to reduce the volume of the driving motor, while avoiding the increase of the height of the periscope camera module, so as to meet the development trend of the miniaturization of electronic devices. It is necessary to develop a motor device with large thrust and small size and volume, and a new driving architecture of the periscope camera module. Among them, the piezoelectric motor is a kind of advanced camera motor scheme with application potential, which has the advantages of large thrust, small size, low power consumption, fast response and no magnetic interference, and the corresponding new driving architecture of the periscope camera module has smaller total height.

[0098] The present application proposes a new driving architecture of the periscope camera module, which comprises an outer frame 100, a carrier 200, a support assembly 400 and a pre-press actuating assembly 300. The pre-press actuating assembly 300 applies a pre-press force to the carrier 200 from the side wall of the carrier 200 in a direction perpendicular to the optical axis, so that the carrier 200 and the pre-press actuating assembly 300 maintain frictional contact and drive the carrier 200 to move in the direction of the optical axis, that is, the carrier 200 is driven to move by means of frictional contact, thereby reducing the volume of the driving structure required for the movement of the carrier 200.

[0099] It should be understood that the pre-press actuating assembly 300 comprises a driving member 310 and a pre-press member 320, and further comprises a conductive assembly 700 for conducting the pre-press actuating assembly 300. The driving member 310, the pre-press member 320 and the conductive assembly 700 are arranged on one side of the carrier 200 in sequence, so that a certain space needs to be reserved in the periscope camera module to arrange the components of the pre-press actuating assembly 300. If the pre-press actuating assembly 300 is arranged on the bottom side and the top side of the carrier 200, the height dimension of the periscope camera module will be increased, which in turn increases the height of the electronic device.

[0100] In order to avoid the above situation, in the present application, the pre-press actuating assembly 300 is arranged on the side of the carrier 200, which not only makes full use of the space on the side of the periscope camera module, but also ensures the compactness and rationality of the overall structure of the periscope camera module, and avoids increasing the height of the periscope camera module.

[0101] Further, in order to ensure the stability of the carrier 200 in the periscope camera module and avoid the carrier 200 from falling off when the device is moved or turned over, the periscope camera module of the present application further comprises a magnetic attraction assembly 600, which is arranged opposite to each other on the outer frame 100 and the carrier 200 and extends along the direction parallel to the optical axis, and exerts a magnetic attraction force on the carrier 200 perpendicular to the direction of the optical axis and the direction of the pre-pressing force. The magnetic attraction assembly 600 comprises a magnetic attraction magnet 610 and a magnetic yoke 620, the magnetic attraction magnet 610 is arranged on one of the carrier 200 and the outer frame 100, and the magnetic yoke 620 is arranged on the other one of the carrier 200 and the outer frame 100, the magnetic attraction force is generated between the magnetic attraction magnet 610 and the magnetic yoke 620, so as to ensure that the carrier 200 does not deviate too much during the long-stroke movement, thereby keeping the carrier 200 stably arranged in the periscope camera module and improving the reliability of the periscope camera module.

[0102] In some embodiments of the present application, the direction of the magnetic attraction force of the magnetic attraction assembly 600 on the carrier 200 is perpendicular to the direction of the pre-pressing force of the pre-pressing actuating assembly 300 on the carrier 200, so as to avoid the pre-pressing force and the magnetic attraction force from being superimposed on each other to generate an excessive driving burden on the pre-pressing actuating assembly 300.

[0103] If the direction of the pre-pressing force is parallel to the direction of the magnetic attraction force, when the direction of the pre-pressing force is the same as the direction of the magnetic attraction force, i.e. the direction of the magnetic attraction force is preferably vertically downward (so as to ensure that the carrier 200 is stably arranged in the periscope camera module), the direction of the pre-pressing force is also vertically downward, in this case, the pre-pressing actuating assembly 300 needs to be arranged on the upper side of the carrier 200, which will increase the height of the periscope camera module, and the pre-pressing force and the magnetic attraction force are superimposed on each other, so that a greater driving force needs to be provided to drive the carrier 200 to move, which will require a greater voltage to be provided to the driving member 310, thereby increasing the volume and size of the driving member 310; when the direction of the pre-pressing force is opposite to the direction of the magnetic attraction force, i.e. the direction of the magnetic attraction force is vertically downward, and the direction of the pre-pressing force is vertically upward, in this case, the pre-pressing actuating assembly 300 needs to be arranged on the bottom side of the carrier 200, which will increase the height of the periscope camera module, and the magnetic attraction force and the pre-pressing force with opposite directions will cancel part or all of the acting force, thereby affecting the driving effect of the pre-pressing actuating assembly 300 and the stability of the carrier 200 on the outer frame 100.

[0104] In addition, the pre-pressing force and the magnetic attraction force are superimposed on each other, which causes the support assembly 400 (e.g., the ball) and the carrier 200 or the support assembly 400 (e.g., the ball) and the outer frame 100 to be severely worn, pits are generated on the surface of the support assembly 400 (e.g., the ball), the surface of the carrier 200, or the surface of the outer frame 100, the driving effect is affected, or debris or damage is generated due to friction, the risk of the support assembly 400 (e.g., the ball) being stuck during operation is increased, and the operation effect is affected.

[0105] Therefore, the pre-pressing force and the magnetic attraction force in different directions and perpendicular to each other can avoid mutual interference between the pre-pressing actuating assembly 300 and the magnetic attraction assembly 600, so that the pre-pressing force and the magnetic attraction force can be maximally exerted, that is, the pre-pressing actuating assembly 300 acts on the side of the carrier 200 to provide driving force for the movement of the carrier 200 along the optical axis direction, and the magnetic attraction assembly 600 is arranged at the bottom to enable the carrier 200 to be stable during long-stroke movement. In other words, the driving effect of the pre-pressing actuating assembly 300 and the stability of the carrier 200 on the outer frame 100 are maximally improved, so that the stability and reliability of the periscope camera module are improved. Moreover, when the pre-pressing force or the size of the pre-pressing force needs to be adjusted, the directions of the pre-pressing force and the magnetic attraction force are perpendicular to each other, so that the pre-pressing actuating assembly 300 located at the side and the magnetic attraction assembly 600 located at the bottom are easier to adjust, the adverse effects of the force directions on the adjustment of the degree of action are reduced, and the interference factors in the adjustment are reduced.

[0106] Further, the directions of the magnetic attraction force of the magnetic attraction assembly 600 on the carrier 200 and the pre-pressing force of the pre-pressing actuating assembly 300 on the carrier 200 are both perpendicular to the optical axis direction, so as to further avoid the interference of the magnetic attraction force and the pre-pressing force on the driving force, and the force received by the carrier 200 is separated into three directions perpendicular to each other, that is, the pre-pressing force in the width direction, the magnetic attraction force in the height direction, and the driving force in the length direction (the optical axis direction). The magnetic attraction assembly 600 is arranged at the bottom of the carrier 200, that is, the magnetic attraction force generated between the magnetic attraction magnet 610 and the magnetic yoke 620 is along the height direction of the periscope camera module (i.e., the outer frame 100), and the pre-pressing force generated by the pre-pressing piece 320 is along the width direction of the periscope camera module (i.e., the outer frame 100).

[0107] In some optional embodiments, the magnetic attraction force is generated between the magnetic attraction piece (e.g., the magnetic attraction magnet 610) located at the carrier 200 and the magnetic yoke 620 located at the outer frame 100, and the magnetic attraction piece and the magnetic yoke 620 form a magnetic attraction structure located at the bottom side of the carrier 200. The magnetic attraction structure can generate a magnetic attraction force to ensure that the carrier 200 does not deviate too much during long-stroke movement. In addition, the magnetic attraction structure located at the bottom side can avoid the superposition of the pre-pressing force and the magnetic attraction force, and the pre-pressing actuating assembly 300 is not subjected to too much driving burden.

[0108] In some embodiments of the present application, the magnetic attraction force direction of the magnetic attraction assembly 600 on the carrier 200 is perpendicular to the pre-pressing force direction of the pre-pressing actuating assembly 300 on the carrier 200, so as to avoid the pre-pressing force and the magnetic attraction force from superimposing on each other to generate excessive driving burden on the pre-pressing actuating assembly 300.

[0109] In specific examples of the present application, the outer frame 100 extends along the optical axis direction to form two side walls from the left and right side edges of the light-in side, and at least one pre-pressing actuating assembly 300 is assembled on one of the side walls of the outer frame 100. The side wall of the outer frame 100 is set as the first side wall 110 of the outer frame 100, and the other side wall opposite to the first side wall 110 of the outer frame 100 is set as the second side wall 120 of the outer frame 100. Similarly, the two side walls of the carrier 200 opposite to the first side wall 110 and the second side wall 120 of the outer frame 100 are correspondingly set as the first carrier side wall 211 and the second carrier side wall 212 of the carrier 200.

[0110] As shown in FIG. 4, the outer frame 100 has a driving member mounting area 111 on the first side wall 110 for assembling the pre-pressing actuating assembly 300. In some specific embodiments, the driving member mounting area 111 of the first side wall 110 of the outer frame 100 can be implemented as a through hole on the first side wall 110 of the outer frame 100 for assisting the installation of the pre-pressing actuating assembly 300. The shape of the through hole on the first side wall 110 of the outer frame 100 corresponds to the outer contour shape of the driving member 310 of the pre-pressing actuating assembly 300, and the size of the through hole is slightly larger than the size of the outer contour shape of the driving member 310.

[0111] More specifically, the outer surface of the first side wall 110 of the outer frame 100 is provided with a mounting groove with a hole diameter slightly larger than that of the through hole along the outer periphery of the through hole, for positioning the mounting position of the pre-pressing actuating assembly 300 from the outside, so as to install the pre-pressing actuating assembly 300.

[0112] In specific examples of the present application, the carrier 200 moves within the space of the outer frame 100 and carries the moving optical assembly, wherein the moving optical assembly includes at least one optical lens. The moving optical assembly is moved by the movement of the carrier 200 to realize the focusing and / or zooming function of the periscopic camera module. In some optional embodiments, the moving optical assembly includes two optical lenses, and the number of carriers 200 corresponds to the number of optical lenses. For example, the carrier 200 is implemented as two moving carriers, and the two moving carriers drive two optical lenses 520 to move along the optical axis direction respectively to realize the zooming and focusing functions.

[0113] Specifically, the carrier 200 is implemented as a lens carrier 210 with a first carrier sidewall 211 and a second carrier sidewall 212, the lens carrier 210 is implemented as a first moving carrier and a second moving carrier respectively carrying optical lenses 520, both the first moving carrier and the second moving carrier have the first carrier sidewall 211 and the second carrier sidewall 212, the first moving carrier and the second moving carrier can be implemented as a split structure or a parent-child structure, when implemented as a split structure, the first moving carrier and the second moving carrier can be respectively driven to move along the optical axis direction to realize the functions of zooming and focusing; when implemented as a parent-child structure, the second moving carrier is movably arranged on the first moving carrier, the first moving carrier drives the second moving carrier to move along the optical axis direction to realize the functions of zooming and focusing.

[0114] Further, the carrier 200 further includes damping members 215 located at the light-in side and the light-out side, i.e. both ends of the carrier 200 along the optical axis direction have damping members 215. Specifically, as shown in FIGS. 13, 16 and 17, both ends of the carrier 200 along the optical axis direction are provided with mounting grooves for mounting the damping members 215, the damping members 215 have protrusions for inserting into the mounting grooves, i.e. the damping members 215 and the mounting grooves are in a clamping structure to realize the mounting of the damping members 215 on the lens carrier 210. When the carrier 200 moves along the optical axis direction, the damping members 215 can realize the functions of limiting and buffering to avoid the impact between the carrier 200 and the outer frame 100, and also can avoid the sound generated due to the impact. Wherein, the protrusions of the damping members 215 and the mounting grooves can also be injected with glue to assist the mounting.

[0115] Further, since the damping members 215 have elasticity, the size of the protrusions of the damping members 215 can be slightly larger than the size of the mounting grooves, and the protrusions of the damping members 215 have a part of extrusion deformation when inserted into the mounting grooves to avoid the damping members 215 falling off after impact.

[0116] Specifically, the damping members 215 are elastic material members, which can be specifically implemented as polyurethane, silicone, epoxy resin or polymer material members.

[0117] In some specific embodiments, the carrier 200 further includes a friction plate 214 in friction contact with the pre-press actuating assembly 300, for the friction between the pre-press actuating assembly 300 and the friction plate 214 of the carrier 200 to drive the carrier 200 to move. Wherein, as shown in FIGS. 4, 6, 12 and 23, the friction plate 214 corresponds to the driving member 310 of the pre-press actuating assembly 300, and extends along the direction parallel to the optical axis on the first carrier sidewall 211 of the carrier 200.

[0118] Specifically, the friction plate 214 is assembled between the carrier 200 and the pre-press actuating assembly 300, the friction plate 214 is implemented as an integral structure of the first carrier side wall 211 of the carrier 200, for example, the friction plate 214 is integrally formed with the first carrier side wall 211 by using an insert molding process; or the friction plate 214 is implemented as a separate structure provided on the first carrier side wall 211 of the carrier 200, for example, the friction plate 214 is connected with the carrier 200 by using an adhesive. It should be understood that the friction plate 214 can increase the friction between the carrier 200 and the pre-press actuating assembly 300.

[0119] In this embodiment, the friction plate 214 is made of a metal oxide plate such as zirconium oxide, aluminum oxide, etc.

[0120] More specifically, referring to FIGS. 6 and 23, the friction contact position 213 of the friction plate 214 and the pre-press actuating assembly 300 is located at the first carrier side wall 211 of the carrier 200. Before the driving member 310 drives the carrier 200, the pre-press member 320 applies a pre-press force to the pre-press actuating assembly 300 to abut against the friction plate 214 of the carrier 200, so as to ensure that the friction head 311 of the pre-press actuating assembly 300 is in friction connection with the friction plate 214.

[0121] It should be noted that the friction contact position 213 mentioned in the foregoing and the following refers to the position at which the elements of the pre-press actuating assembly 300 or the first support portion 410 or the second support portion 420 or the third support portion 430 of the support assembly 400 mentioned in the following come into contact with the carrier 200 or the outer frame 100. The contact can be surface friction or point friction, and can be rolling friction or sliding friction. However, since it is uncertain, it is not explicitly shown in the drawings.

[0122] As shown in FIGS. 5, 6 and 21, in the above-mentioned periscopic camera module, the carrier 200 is mainly subjected to the pre-press force in the third axis X direction (i.e. the width direction of the outer frame 100 or the carrier 200), the magnetic attraction force in the first axis Z direction (i.e. the height direction of the outer frame 100 or the carrier 200), and the driving force in the second axis Y direction (i.e. the length direction of the outer frame 100 or the carrier 200, which is parallel to the optical axis). It should be understood that since the piezoelectric vibrator 312 of the driving member 310 moves the friction head 311 by vibration deformation, when the piezoelectric vibrator 312 vibrates and deforms, the angle at which the friction head 311 abuts against the carrier 200 changes, which causes the force generated between the friction head 311 and the carrier 200 to not always be parallel to the optical axis direction. The direction of the force has a certain inclination relative to the plane in which the side wall of the carrier 200 is located, and the action of the inclined force can cause the carrier 200 to tilt.

[0123] Further, the pre-pressing member 320 provides a pre-pressing force for the driving member 310, the direction of the pre-pressing force is perpendicular to the side wall of the carrier 200 along the first axis Z, but due to the vibration deformation of the piezoelectric vibrator 312, the angle of the friction head 311 abutting against the carrier 200 changes, which causes the direction of the pre-pressing force not always perpendicular to the side wall of the carrier 200, but the direction of the pre-pressing force has a certain inclination relative to the plane where the side wall of the carrier 200 is located. Meanwhile, the piezoelectric vibrator 312 of the pre-pressing actuating assembly 300 drives the friction head 311 to move through vibration deformation, the pre-pressing member 320 will also deform due to the vibration deformation of the piezoelectric vibrator 312, which also causes the direction of the pre-pressing force generated by the pre-pressing member 320 to have a certain inclination relative to the plane where the side wall of the carrier 200 is located, so that the carrier 200 has the possibility of tilting or even overturning.

[0124] In the specific example of the present application, the pre-pressing actuating assembly 300 is distributed on the first side wall 110 of the outer frame 100 along the direction parallel to the optical axis, and the pre-pressing member 320 of the pre-pressing actuating assembly 300 applies a pre-pressing force perpendicular to the optical axis direction along the direction from the first carrier side wall 211 of the carrier 200 to the second carrier side wall 212, for keeping the carrier 200 and the pre-pressing actuating assembly 300 in frictional contact at all times, so as to drive the carrier 200 to move relative to the outer frame 100 along the optical axis direction, to realize focusing and zooming functions.

[0125] When focusing and zooming operations are performed, the first carrier side wall 211 of the carrier 200 will be subjected to the pre-pressing force perpendicular to the optical axis direction applied by the pre-pressing actuating assembly 300, in order to better withstand the pre-pressing force from the pre-pressing actuating assembly 300, it is preferred that the length of the first carrier side wall 211 of the carrier 200 along the optical axis is not less than the length of the second carrier side wall 212 of the carrier 200 along the optical axis.

[0126] Correspondingly, the length of the friction plate 214 of the carrier 200 can be set to be longer, so as to further prolong the stroke of the pre-pressing actuating assembly 300.

[0127] In an embodiment, the length of the first carrier side wall 211 of the carrier 200 along the optical axis is equal to the length of the second carrier side wall 212 of the carrier 200 along the optical axis, so as to increase the setting length of the support portions disposed on the opposite sides of the pre-pressing actuating assembly 300 (for example, the distance between the two rolling balls disposed along the optical axis), thereby increasing the support surface area formed by the different support portions for the carrier 200, to further enhance the movement stability and parallelism of the carrier 200.

[0128] Specifically, when focusing and zooming operations are performed, the first carrier side wall 211 of the carrier 200 will be subjected to a pre-pressing force exerted by the pre-pressing actuating assembly 300 in a direction perpendicular to the optical axis. In addition, during movement, the carrier 200 can also tend to deviate towards the second side wall 120 of the outer frame 100, and generate up-and-down deviation on the bottom surface of the outer frame 100. In order to prevent these deviations and ensure that the carrier 200 moves smoothly along the optical axis direction during the entire focusing and zooming process, the support assembly 400 is carefully designed and assembled between the carrier 200 and the outer frame 100 to provide the necessary support and guiding effect.

[0129] Since the pre-pressing actuating assembly 300 is driven on the side of the carrier 200, the pre-pressing member 320 provides a pre-pressing force perpendicular to the first carrier side wall 211 of the carrier 200, and thus a part of the support members in the support assembly 400 need to support the carrier 200 on the side of the carrier 200. On the one hand, this can avoid excessive friction force caused by surface friction between the carrier 200 and the outer frame 100, and on the other hand, it can improve the parallelism of the movement of the carrier 200 through the configuration of the support members (e.g. balls) and linear grooves. If the support members are all placed on the opposite side (i.e. the second side) of the pre-pressing actuating assembly 300 under the action of the pre-pressing force, the carrier 200 will have a large overturning moment due to the long force arm, which will further increase the risk of tilting of the carrier 200. In the state where the pre-pressing actuating assembly 300 is not powered, the linear distance from the support member to the friction contact position 213 is the overturning arm of the carrier 200.

[0130] Specifically, in the state where the driving member 310 is not powered, the linear distance from the friction head 311 of the driving member 310 to the support member is the force arm x of the driving force. According to the formula M = Fx, when x is larger, i.e. the linear distance from the friction head 311 to the support member is farther in the state where the driving member 310 is not powered, the overturning moment M is larger, and the carrier 200 is more likely to tilt when it is driven to move along the optical axis direction, which further increases the risk of the carrier 200 being stuck and unable to continue moving.

[0131] In addition, when the support member is implemented as a ball or other support member in point frictional contact with the carrier 200 but with uncertain motion state, taking the ball as an example, the motion state of the ball is uncertain when it is assembled between the carrier 200 and the outer frame 100, and the ball can randomly switch between rolling and sliding motion states, so that the ball can be stuck in the assembly groove during the movement of the carrier 200, which can also cause the carrier 200 to tilt or even overturn. When the support assembly 400 is implemented as a plurality of balls, the balls are in point contact with the outer frame 100 and the carrier 200 on both sides, and if the carrier 200 tilts, one of the balls of the support assembly 400 can not be in contact with the outer frame 100 and the carrier 200 at the same time, which can cause the carrier 200 to be stuck or separated from the ball, and thus the carrier 200 cannot continue to move. On this basis, considering the movable space size of the ball assembly, the manufacturing tolerances of the outer frame 100 and the carrier 200 and the assembly tolerances therebetween can also cause the carrier 200 to tilt or be stuck.

[0132] More specifically, the support assembly 400 is implemented as a plurality of support members, at least one of which is assembled between the first side of the outer frame 100 and the first side of the carrier 200, and at least another of which is assembled between the second side of the outer frame 100 and the second side of the carrier 200. In other words, at least one of the support members is assembled between the inner side wall of the outer frame 100 provided with the pre-pressing actuating assembly 300 and the opposite outer side wall of the carrier 200, and at least another of the support members is assembled between the other inner side wall of the outer frame 100 not provided with the pre-pressing actuating assembly 300 and the other outer side wall of the carrier 200 opposite to it, i.e. at least one of the support members is assembled between the first side wall 110 of the outer frame 100 and the first carrier side wall 211 of the carrier 200, and at least another of the support members is assembled between the second side wall 120 of the outer frame 100 and the second carrier side wall 212 of the carrier 200, so that the carrier 200 is supported by the support members at both sides of the left and right side walls and / or the left and right sides of the bottom surface parallel to the optical axis direction, thereby ensuring that the carrier 200 always moves along the optical axis direction. In some optional embodiments, and at least two of the support members are assembled on both sides of the frictional contact position 213 of the pre-pressing actuating assembly 300 and the carrier 200 in the height direction, i.e. along the thickness direction of the outer frame 100, so that when the carrier 200 moves in the optical axis direction, the offset or even sticking of the carrier 200 in the horizontal plane and in the height direction during zooming and focusing is reduced.

[0133] In the specific example of the present application, the support assembly 400 comprises a first support portion 410 and a second support portion 420, each having at least one support member, the first support portion 410 being arranged at the first side wall 110 of the outer frame body 100 where the pre-pressing actuating assembly 300 is arranged, and the second support portion 420 being arranged at the second side wall 120 of the outer frame body 100 corresponding to the first side wall 110, as shown in FIGS. 6 and 22. Under the action of the pre-pressing force, the first support portion 410 is clamped between the bottom of the first side wall 110 of the outer frame body 100 and the bottom of the first carrier side wall 211 of the carrier 200, and the second support portion 420 is clamped between the top of the second side wall 120 of the outer frame body 100 and the top of the second carrier side wall 212 of the carrier 200, thereby supporting the carrier 200.

[0134] Preferably, the first support portion 410 and the second support portion 420 are assembled on the upper and lower sides of the contact position 213 of the pre-pressing actuating assembly 300 and the carrier 200 in the height direction (i.e., along the thickness direction of the outer frame body 100), and the distance from the first support portion 410 to the contact position 213 in the height direction is equal to or close to (the difference is not more than 20%) the distance from the second support portion 420 to the contact position 213 in the height direction, so that the first support portion 410 and the second support portion 420 are arranged as symmetrically as possible relative to the optical axis in the height direction, thereby providing the carrier 200 with as symmetrical a support force as possible and reducing the risk of the carrier 200 being overturned without structural interference.

[0135] Specifically, according to the formula for calculating the moment of force M = Fx, where M is the overturning moment, F is the pre-pressing force vector, and x is the force arm of the pre-pressing force, i.e., the straight-line distance from the friction contact position 213 of the pre-pressing actuating assembly 300 and the carrier 200 to the second support portion 420 when the pre-pressing actuating assembly 300 is not energized (the straight-line distance from the first support portion 410 to the friction contact position 213 approaches zero). When the pre-pressing force F is constant, the overturning moment M increases with the increase of the force arm x. When the value of x is larger, i.e., the distance from the friction contact position 213 of the pre-pressing actuating assembly 300 and the carrier 200 to the second support portion 420 is farther, the overturning moment M is larger, and the carrier 200 is more likely to tilt when moving along the optical axis, thereby increasing the risk of the carrier 200 being stuck. Therefore, the value of x can be controlled by controlling the straight-line distance between the second support portion 420 and the contact position 213, thereby controlling the overturning moment M.

[0136] Correspondingly, the first side wall 110 of the outer frame body 100 and the first carrier side wall 211 of the carrier 200 each have at least two abutting faces abutting against the first support part 410, and the second side wall 120 of the outer frame body 100 and the second carrier side wall 212 of the carrier 200 each have at least one abutting face abutting against the second support part 420. As shown in FIGS. 8, 9, 24 and 25, the abutting faces of the first support part 410 or the second support part 420 at least include a vertical face perpendicular to the pre-pressing direction, i.e., the first abutting face 112 and the second abutting face 121, to provide abutting support for the first support part 410 or the second support part 420 under the pre-pressing force.

[0137] In some embodiments, when the first support part 410 and / or the second support part 420 are implemented by two or more support members sequentially distributed along the direction parallel to the optical axis, the assembly areas of the first support part 410 and the second support part 420 on the outer frame body 100 and the carrier 200 each have an assembly groove corresponding to the support member, and each assembly groove has at least two oppositely arranged abutting faces. As shown in FIGS. 8, 9, 24 and 25, the assembly groove is implemented to have two vertical faces and two horizontal faces, so that the support member can be abuttingly supported from the vertical direction and the horizontal direction. For example, the first abutting face 112 on the first side wall 110 of the outer frame body 100 and the third abutting face 2111 on the first carrier side wall 211 of the carrier 200 are both vertical abutting faces, abuttingly supporting the first support part 410 from two horizontal directions; the outer frame body 100 and the carrier 200 each have a horizontal abutting face on the upper and lower sides of the first support part 410, abuttingly supporting the first support part 410 from two vertical directions; the second abutting face 121 on the second side wall 120 of the outer frame body 100 and the fourth abutting face 2121 on the second carrier side wall 212 of the carrier 200 are both vertical abutting faces, abuttingly supporting the second support part 420 from two horizontal directions; as shown in FIG. 25, the first abutting face 112 on the first side wall 110 of the outer frame body 100 and the second support part 420 are abuttingly supported by an additional structure, which is a metal member 480, to further adjust the manufacturing tolerance between the first abutting face 112 on the first side wall 110 of the outer frame body 100 and the second support part 420; the outer frame body 100 and the carrier 200 each have a horizontal abutting face on the upper and lower sides of the second support part 420, abuttingly supporting the second support part 420 from two vertical directions.

[0138] In order to reduce the risk of carrier 200 tilting, the application sets the support part close to one side (i.e. the first side) of the pre-pressing actuating assembly 300 as tight fitting, i.e. the first support part 410 arranged on the same side as the pre-pressing actuating assembly 300 is the main support; sets the support part away from one side (i.e. the second side) of the pre-pressing actuating assembly 300 as loose fitting, i.e. the second support part 420 arranged on the opposite side of the pre-pressing actuating assembly 300 is the auxiliary support. As shown in FIGS. 8, 9, 24 and 25, the first support part 410 is tightly fitted between the first side wall 110 of the outer frame 100 and the first carrier side wall 211 of the carrier 200, and the second support part 420 is loosely fitted between the second side wall 120 (or the metal piece 480) of the outer frame 100 and the second carrier side wall 212 of the carrier 200, i.e. the first support part 410 is always in abutment with the first abutment surface 112, the third abutment surface 2111 and the horizontal abutment surface located on both sides of the first support part 410, and the second support part 420 is always in abutment with the second abutment surface 121 (or one side wall of the metal piece 480), the fourth abutment surface 2121 and the horizontal abutment surface located on the upper side of the second support part 420, i.e. there is a certain gap between the second support part 420 and the second abutment surface 121, the fourth abutment surface 2121 and the horizontal abutment surface located on the upper side of the second support part 420. When the carrier 200 moves along the optical axis direction, the first support part 410 is the main support part, so that the straight line distance from the first support part 410 to the above-mentioned contact position 213 is less than the straight line distance from the projection of the second support part 420 on the first side wall 110 of the outer frame 100 to the above-mentioned contact position 213 in the state that the pre-pressing actuating assembly 300 is not powered. Since the first support part 410 is tightly fitted, the straight line distance from the above-mentioned contact position 213 to the first support part 410 is the force arm x corresponding to the overturning moment, so as to reduce the value of x and thus reduce the overturning moment M, thereby avoiding the problem of tilting or even jamming of the carrier 200.

[0139] The tight fit and the loose fit can be implemented by tolerances in the assembly process, for example, the tolerance of the first support part 410 with the outer frame 100 and the carrier 200 is smaller than the tolerance of the second support part 420 with the outer frame 100 and the carrier 200, for example, the former is 0.01 and the latter is 0.02. That is, the distance between the first abutting surface 112 and the third abutting surface 2111 is smaller than the distance between the second abutting surface 121 and the fourth abutting surface 2121, and the distance between the horizontal abutting surfaces on the upper and lower sides of the first support part 410 is smaller than the distance between the horizontal abutting surfaces on the upper and lower sides of the second support part 420. When the carrier 200 is not tilted, the first support part 410 that is tightly fitted provides main support for the carrier 200 to ensure the parallelism of the movement of the carrier 200 along the optical axis; when the carrier 200 is tilted, the gap at the second support part 420 that is loosely fitted can provide space for the carrier 200 to adjust the position, and when tilted to a certain angle, the second support part 420 simultaneously abuts the outer frame 100 and the carrier 200, and cooperates with the first support part 410 in this state to provide support for the carrier 200, thereby correcting the position of the carrier 200 to avoid the angle of the tilted carrier 200 affecting the movement of the carrier 200, to some extent, reducing the possibility of the carrier 200 being tilted, and helping to improve the imaging quality of the periscopic camera module.

[0140] In some optional embodiments, the first support part 410 or the second support part 420 can be implemented as a ball or other support point-shaped support member, and the first support part 410 and / or the second support part 420 each includes two balls, and the balls are respectively assembled at the front and rear ends of the carrier 200 along the parallel optical axis direction, as shown in FIGS. 12, 13, 28, 29 and 30, the first support part 410 and the second support part 420 are each implemented as two balls, that is, the first ball 411 and the second ball 412 that constitute the first support part 410, and the third ball 421 and the fourth ball 422 that constitute the second support part 420. Under the action of the pre-pressure, the balls are clamped between the outer frame 100 and the carrier 200 to provide more stable support and movement guidance for the carrier 200.

[0141] In some optional embodiments, the first support part 410 or the second support part 420 can be implemented as a guide rod or other surface support member, which extends along the parallel optical axis direction and is assembled between the outer frame 100 and the carrier 200 to ensure the parallelism and stability of the movement of the carrier 200. As shown in FIGS. 14-17 and 30, the first support part 410 is implemented as the first ball 411 and the second ball 412, and the second support part 420 is implemented as the top guide rod 423.

[0142] In some specific examples, as shown in FIGS. 6, 8, 9, 22, and 24, when the first support portion 410 and the second support portion 420 are implemented as two balls, the corresponding abutting surfaces of the first side wall 110 of the outer frame 100 and the corresponding abutting surfaces of the first carrier side wall 211 of the carrier 200 are respectively recessed into the outer frame 100 and the carrier 200, forming at least one pair of L-shaped guide grooves 440 with opposite opening directions, i.e., the first abutting surface 112, the second abutting surface 121, the third abutting surface 2111, or the fourth abutting surface 2121 can be connected with an adjacent horizontal abutting surface to form an L-shaped guide groove 440; as shown in FIGS. 6, 8, 9, 25, 31, 32, and 33, one side wall of the metal piece 480 can also be connected with an adjacent horizontal abutting surface to form an L-shaped guide groove 440. Under the action of the pre-pressure, the four inner walls of each pair of L-shaped guide grooves 440 are simultaneously clamped on the outside of the ball of the first support portion 410, i.e., the first abutting surface 112, the third abutting surface 2111, and the horizontal abutting surfaces located on the upper and lower sides of the ball of the first support portion 410 all abut the ball of the first support portion 410, so as to realize the tight fit of the first support portion 410; the other three inner walls of the pair of L-shaped guide grooves 440 except the bottom surface all maintain a certain gap with the ball of the second support portion 420, i.e., the second abutting surface 121, the fourth abutting surface 2121, and the horizontal abutting surface located on the upper side of the ball of the second support portion 420 all maintain a certain gap with the ball of the first support portion 410, so as to realize the loose fit of the second support portion 420, and avoid the ball of the first support portion 410 or the second support portion 420 from loosening or falling off.

[0143] In an embodiment of the present application, the size of the ball of the first support portion 410 on the same side of the pre-pressure actuating assembly 300 is greater than the size of the ball of the second support portion 420 on the opposite side of the pre-pressure actuating assembly 300. It should be understood that the ball of the first support portion 410 is located at the bottom of the first side, and the ball of the second support portion 420 is located at the top of the second side. Such arrangement makes the ball of the first support portion 410 receive a greater force and be more likely to produce a dent when the periscopic camera module falls or is impacted, because the ball of the first support portion 410 is arranged between the bottom of the first side wall 110 of the outer frame 100 and the bottom of the first carrier side wall 211 of the carrier 200 to support the entire carrier 200.

[0144] Further, since the first support portion 410 is arranged in a tight fit, i.e., the four sides of the ball of the first support portion 410 abut the L-shaped guide groove 440, and the second support portion 420 is arranged in a loose fit, i.e., at least one side of the ball of the second support portion 420 has a gap with the L-shaped guide groove 440, so as to alleviate the impact received by the ball of the second support portion 420, the ball of the first support portion 410 receives a greater force and is more likely to produce a dent when the periscopic camera module falls or is impacted.

[0145] Specifically, the ball size of the first support part 410 is designed to be larger, so as to disperse the force when the ball of the first support part 410 is impacted, and reduce the degree of concave of the first support part 410.

[0146] In some optional embodiments, a metal support is arranged on the first side wall 110 of the outer frame 100, which is located at the bottom of the second support part 420 and supports the second support part 420 upward from the top surface thereof, so as to provide a support plane for the ball of the second support part 420, so as to improve the smoothness of the movement of the second support part 420 and avoid the concave of the ball in the guide groove or the debris on the outer frame 100 after the ball is pressed.

[0147] As shown in FIGS. 6, 8, 9, 22, 24 and 25, the interval of the pair of L-shaped guide grooves 440 clamping the outer side of the ball of the second support part 420 is greater than the interval of the pair of L-shaped guide grooves 440 clamping the outer side of the ball of the first support part 410. In some optional embodiments, the horizontal interval of the pair of L-shaped guide grooves 440 clamping the outer side of the ball of the second support part 420 is greater than the horizontal interval of the pair of L-shaped guide grooves 440 clamping the outer side of the ball of the first support part 410, so as to realize the tight fit of the first support part 410 and the loose fit of the second support part 420. Further, as shown in FIGS. 6, 8, 9, 22, 24 and 25, the horizontal interval and the vertical interval of the pair of L-shaped guide grooves 440 clamping the outer side of the ball of the second support part 420 are both greater than the horizontal interval and the vertical interval of the pair of L-shaped guide grooves 440 clamping the outer side of the ball of the first support part 410, so as to realize the loose fit of the second support part 420, so that the carrier 200 in the inclined state has sufficient adjustment space to avoid being stuck, so as to ensure the stable movement of the ball in the L-shaped guide groove 440.

[0148] Specifically, the two balls constituting the same support part are located in the two pairs of L-shaped guide grooves 440, which are arranged along the direction parallel to the optical axis but are not communicated with each other, i.e., each ball is located in a pair of L-shaped guide grooves 440, so as to avoid the interference between the two balls.

[0149] The length of the L-shaped guide groove 440 along the optical axis direction is greater than the diameter of the ball, so that the ball can move along the optical axis direction in the L-shaped guide groove 440. It can be understood that the longer the length of the L-shaped guide groove 440 along the optical axis direction, the greater the chance of pure rolling of the ball, and the smaller the friction coefficient of pure rolling, so that the carrier 200 receives smaller friction force, and the movement of the carrier 200 along the optical axis direction is more stable.

[0150] In some embodiments, the length of the L-shaped guide slot 440 along the optical axis direction for accommodating the first support portion 410 can be equal to the length of the L-shaped guide slot 440 along the optical axis direction for accommodating the second support portion 420, so as to ensure a long moving stroke of the carrier 200.

[0151] Since the carrier 200 moves along the optical axis direction, in order to ensure that the support assembly 400 is always clamped and cannot fall off, as shown in FIGS. 6 and 7, a magnetic attraction assembly 600 is arranged between the carrier 200 and the outer frame 100, so that the carrier 200 is subjected to a magnetic attraction force towards the outer frame 100 during movement along the optical axis direction, so as to clamp the support assembly 400, thereby reducing the offset of the carrier 200 moving along the optical axis direction and maintaining the parallelism of the movement.

[0152] In some embodiments, as shown in FIGS. 6, 7 and 22, the magnetic attraction assembly 600 is arranged between the bottom of the carrier 200 and the bottom of the outer frame 100, and includes a magnetic attraction magnet 610 and a magnetic yoke 620, i.e., the magnetic attraction magnet 610 is arranged on one of the carrier 200 and the outer frame 100, and the magnetic yoke 620 is arranged on the other one of the carrier 200 and the outer frame 100. Preferably, the magnetic attraction magnet 610 is arranged on the bottom surface of the carrier 200, and the magnetic yoke 620 is arranged on the outer frame 100 at a position corresponding to the magnetic attraction magnet 610, and both the magnetic attraction magnet 610 and the magnetic yoke 620 extend along the optical axis direction.

[0153] In some embodiments, the magnetic attraction assembly 600 and the first support portion 410 are symmetrically arranged on the bottom of the carrier 200, i.e., at least one magnetic attraction magnet 610 and the first support portion 410 are symmetrically arranged on the bottom of the carrier 200 in the width direction, as shown in FIG. 34, the magnetic attraction magnet 610 is arranged on the other side of the bottom of the carrier 200 away from the first support portion 410, and the magnetic yoke 620 is correspondingly arranged on the bottom of the side wall of the outer frame 100 without the pre-pressing actuating assembly 300. Since the first support portion 410 is tightly fitted to the first side of the outer frame 100 and the first side of the carrier 200, the magnetic attraction assembly 600 is arranged on the bottom of the carrier 200 closer to the second side of the outer frame 100 and the second side of the carrier 200 in the width direction, and generates a downward magnetic attraction force on the carrier 200, so that the symmetrically arranged two sides of the bottom of the carrier 200 in the width direction are subjected to a downward force, so as to ensure the stability of the carrier 200 on the outer frame 100.

[0154] The magnetic assembly 600 comprises at least one magnetic magnet 610 and a magnetic yoke 620. In some embodiments, the number of the magnetic magnets 610 is at least two, and the two magnetic magnets 610 are symmetrically arranged on the two sides of the bottom of the carrier 200 along the width direction and extend along the direction parallel to the optical axis. The magnetic yoke 620 is arranged on the outer frame 100 at the position corresponding to the projection of the magnetic magnet 610 on the outer frame 100 and extends along the direction parallel to the optical axis. As shown in FIGS. 6, 7, 23 and 27, the two sets of magnetic magnets 610 and magnetic yokes 620 on the two sides of the bottom of the carrier 200 generate magnetic attraction. The two sets of magnetic magnets 610 are symmetrically arranged on the bottom of the carrier 200, so that the carrier 200 is subjected to symmetric magnetic attraction force perpendicular to the optical axis direction, thereby further reducing the deviation of the carrier 200 during movement and maintaining the parallelism of the movement. In some embodiments, the magnetic assembly 600 further comprises a magnetic magnet 610 arranged on one side wall or both side walls of the carrier 200 and a magnetic yoke 620 arranged on the inner side wall of the outer frame 100 at the corresponding position, for generating magnetic attraction force in the third direction X to ensure the parallelism of the movement of the carrier 200.

[0155] In some embodiments, at least one magnetic magnet 610 is arranged on one side or both sides of the carrier 200 along the third direction X. As shown in FIGS. 12, 13, 15, 16, 28, 29 and 30, two magnetic magnets 610 are arranged on the two sides of the bottom of the carrier 200, and the length of each magnetic magnet 610 is not less than half of the length of the carrier 200 along the optical axis direction.

[0156] In some embodiments, two magnetic magnets 610 are arranged on each of the two sides of the bottom of the carrier 200, and the two magnetic magnets 610 on the same side are arranged along the optical axis direction. The length of each magnetic magnet 610 is not less than one third of the length of the carrier 200 along the optical axis direction, so as to ensure the stability of the movement of the carrier 200 in the outer frame 100.

[0157] In some embodiments, the magnetic yoke 620 is arranged at the projection of the magnetic magnet 610 on the outer frame 100 and extends along the optical axis direction. The magnetic yoke 620 can be fixed on the outer frame 100 by means of adhesion, clamping, nesting, welding or fastening. In particular, in order to ensure that the carrier 200 is always subjected to downward magnetic attraction force during movement, the length of the magnetic yoke 620 along the optical axis direction is not less than the movement stroke of the carrier 200.

[0158] Preferably, the length of the magnetic yoke 620 is not less than the sum of half of the length of the carrier 200 along the optical axis and the moving stroke of the carrier 200, so as to avoid the carrier 200 from being offset due to the magnetic attraction force being too small when the carrier 200 moves to one end of the magnetic yoke 620, because the setting position of the magnetic attracting magnet 610 is too forward or too backward.

[0159] In some optional embodiments, when the carrier 200 is implemented as two carriers 200 arranged in sequence along the optical axis, the magnetic yokes 620 corresponding to the two carriers 200 are located at different positions in the third direction X and extend along the optical axis.

[0160] Specifically, when the magnetic yokes 620 corresponding to the two carriers 200 are located in the same direction parallel to the optical axis, the magnetic yoke 620 can be implemented as an integral magnetic yoke 620 or two segmented magnetic yokes 620 corresponding to the moving strokes of the two carriers 200 respectively, so as to cover the moving strokes of the two carriers 200.

[0161] In some specific embodiments, the magnetic yoke 620 includes a planar section 621 and an edge section 623, the planar section 621 covers the projection of the magnetic attracting magnet 610 on the outer frame 100 and the moving stroke of the carrier 200, and is used to generate a magnetic attraction force with the magnetic attracting magnet 610 on the carrier 200, and the edge section 623 connects the planar section 621 and the outer frame 100.

[0162] In some optional embodiments, the magnetic attraction assembly 600 is implemented as a group of magnetic attraction assemblies 600 and is symmetrically arranged on both sides of the bottom of the carrier 200 in the third direction X with the first support part 410, the magnetic attracting magnet 610 is arranged on the other side of the bottom of the carrier 200 away from the first support part 410, and the magnetic yoke 620 can be implemented to extend to the first support part 410 in the third direction X, or to cover the width of the carrier 200, or to cover only the projection of the magnetic attracting magnet 610, that is, the planar section 621 of the magnetic yoke 620 covers the projection of the magnetic attracting magnet 610, and the edge section 623 of the magnetic yoke 620 can be implemented to extend from one side or both sides of the planar section 621 to the first support part 410 in the third direction X, or to cover the width of the carrier 200, or to cover only one side of the bottom surface of the carrier 200.

[0163] Specifically, the width of the magnetic attracting magnet 610 in the third direction X is not less than one fourth of the width of the carrier 200, so as to ensure that the carrier 200 receives similar or same downward acting force on both sides of the bottom, thereby avoiding the carrier 200 from being offset.

[0164] In some optional embodiments, the magnetic yoke 620 further comprises a bending section 622 between the planar section 621 and the edge section 623, as shown in FIG. 22 and FIG. 28, the bending section 622 is raised from the opposite sides of the planar section 621 and the edge section 623 to form a support surface, which supports the first support portion 410 at the top, at this time, the planar section 621 covers the projection of the magnetic magnet 610 on the outer frame 100 in the width direction and extends to the first support portion 410 on one side.

[0165] Specifically, the planar section 621 covers the projection of the magnetic magnet 610 on the outer frame 100 in the third direction X, and is connected to the edge section 623 and the bending section 622 on both sides, respectively, and the other edge section 623 on the other side, so as to cover the bottom surface of the carrier 200, thereby making the magnetic force received by the carrier 200 more stable.

[0166] Further, the planar section 621 comprises a projection area 6211 and a connection area 6212, as shown in FIG. 28, the projection area 6211 only covers the projection of the magnetic magnet 610, and the connection area 6212 connects the projection area 6211 and other sections of the magnetic yoke 620 and / or connects two adjacent projection areas 6211.

[0167] Specifically, when the magnetic magnet 610 is only located on one side of the bottom of the carrier 200 away from the first support portion 410 in the third direction X, the projection area 6211 of the planar section 621 only covers the projection of the magnetic magnet 610 on the outer frame 100 in the third direction X, and the connection area 6212 of the planar section 621 connects the edge section 623 and the bending section 622; when the magnetic magnet 610 is symmetrically arranged on both sides of the bottom of the carrier 200 in the third direction X, the projection area 6211 of the planar section 621 only covers the projection of the magnetic magnet 610 on the outer frame 100 in the third direction X, and the connection area 6212 of the planar section 621 connects the projection area 6211 and the edge section 623 and the bending section 622, and connects two adjacent projection areas 6211.

[0168] Preferably, the connection area 6212 of the planar section 621 has a hollow hole to further reduce the mass of the magnetic yoke 620.

[0169] In some embodiments of the present application, the magnetic yoke 620 is implemented as a metal material strip capable of being attracted to the magnetic magnet 610, that is, it can be mass-produced, and the magnetic yoke 620 is cut into the required area after being manufactured into a shape to improve manufacturing efficiency. Moreover, the magnetic yoke 620 has a larger area, and the larger the metal pressing area, the more conducive to ensuring the flatness of the area on the outer frame 100 corresponding to the carrier 200.

[0170] In the specific example of the present application, the support assembly 400 further comprises a third support part 430 assembled between the outer frame 100 and the carrier 200, which is clamped between the bottom of the outer frame 100 and the bottom of the carrier 200 under the magnetic attraction of the magnetic attraction assembly 600, as shown in FIGS. 6, 8, 22 and 24. Under the magnetic attraction, the first support part 410 and the third support part 430 are clamped between the bottom of the outer frame 100 and the bottom of the carrier 200 and are located on both sides of the bottom of the carrier 200, respectively. The third support part 430 and the first support part 410 are symmetrically arranged relative to the optical axis along the width direction of the carrier 200 and the outer frame 100 (the length direction of the carrier 200 and the outer frame 100 is taken as the optical axis direction) as much as possible, so as to provide the carrier 200 with as symmetrical support force as possible and reduce the risk of the carrier 200 being tilted.

[0171] Correspondingly, the second side wall 120 of the outer frame 100 and the second carrier side wall 212 of the carrier 200 each have at least one abutting surface abutting the third support part 430. As shown in FIGS. 6 and 22, the abutting surface of the third support part 430 includes at least two horizontal surfaces perpendicular to the direction of the magnetic attraction, so as to provide abutting support for the upper and lower sides of the third support part 430 under the magnetic attraction.

[0172] Specifically, the third support part 430 is clamped between the bottom of the second side wall 120 of the outer frame 100 and the bottom of the second carrier side wall 212 of the carrier 200. When the carrier 200 is moved along the optical axis under the action of the pre-pressure, the carrier 200 is mainly supported by the tightly fitted first support part 410, is secondarily supported by the loosely fitted second support part 420, and is kept moving along the optical axis direction under the magnetic attraction between the two groups of magnetic attraction magnets 610 and magnetic yokes 620 on both sides of the bottom of the carrier 200.

[0173] Among them, in order to reduce the probability of the carrier 200 being tilted towards the second side wall 120 of the outer frame 100 under the action of the pre-pressure, the third support part 430 has a certain adjustment gap in the direction parallel to the pre-pressure direction, and the third support part 430 does not have an adjustment gap in the direction of the magnetic attraction, so that the ball of the third support part 430 is always clamped under the action of the magnetic attraction, even if the corresponding pair of assembly grooves may be horizontally misaligned under the action of the pre-pressure, the ball of the third support part 430 can still stably move in the pair of assembly grooves. The above adjustment gap can be implemented by tolerances in the assembly process, for example, the left and right distance of the pair of assembly grooves of the ball of the third support part 430 is greater than the up and down distance.

[0174] As shown in FIG. 6 and FIG. 22, the first support part 410 and the third support part 430 are respectively located at the bottom of the first carrier sidewall 211 and the bottom of the second carrier sidewall 212 of the carrier 200, and the second support part 420 and the third support part 430 are respectively located at the top and the bottom of the second carrier sidewall 212 of the carrier 200. During the movement of the carrier 200, the first support part 410 and the second support part 420 are clamped between the carrier 200 and the outer frame 100 under the action of the pre-pressure, thereby providing horizontal support for the carrier 200, and the first support part 410 and the third support part 430 are clamped between the carrier 200 and the outer frame 100 under the action of the magnetic attraction, thereby providing vertical support for the carrier 200.

[0175] More specifically, the first support part 410 supports the carrier 200 under the action of both the pre-pressure and the magnetic attraction, so the first support part 410 needs to be limited in the direction parallel to the pre-pressure and the direction parallel to the magnetic attraction. As shown in FIG. 6, FIG. 8, FIG. 9, FIG. 10 and FIG. 22, the first support part 410 needs to be limited in the horizontal direction and the vertical direction perpendicular to the optical axis. The second support part 420 supports the carrier 200 under the action of the pre-pressure, so the second support part 420 needs to be limited in the direction parallel to the pre-pressure and can have a certain movement space in the direction parallel to the magnetic attraction, i.e. the second support part 420 needs to be limited in the horizontal direction perpendicular to the optical axis and can have a certain movement space in the vertical direction perpendicular to the optical axis. The third support part 430 supports the carrier 200 under the action of the magnetic attraction, so the third support part 430 needs to be limited in the direction parallel to the magnetic attraction and can have a certain movement space in the direction parallel to the pre-pressure, i.e. the third support part 430 needs to be limited in the vertical direction perpendicular to the optical axis and can have a certain movement space in the horizontal direction perpendicular to the optical axis.

[0176] Correspondingly, when the first support part 410 and the third support part 430 are symmetrically arranged at the bottom of the carrier 200, the magnetic attraction magnet 610 is implemented as two magnetic attraction magnets 610 symmetrically arranged at the first support part 410 and the third support part 430, and the magnetic yoke 620 sequentially has the edge section 623, the bending section 622 and the plane section 621 from both sides to the center. The plane section 621 covers the projection of the two magnetic attraction magnets 610 on the outer frame 100, the edge section 623 and the bending section 622 are symmetrically distributed on both sides of the plane section 621 in the width direction, and the two bending sections 622 are respectively located at the bottom of the first support part 410 and the third support part 430 and support the first support part 410 and the third support part 430 upward from the top surface.

[0177] In some optional embodiments, the third support portion 430 can be implemented as two balls, which are respectively assembled at the front and rear ends of the carrier 200 along the direction parallel to the optical axis. Under the action of magnetic attraction, the balls are clamped between the outer frame 100 and the carrier 200 to provide more stable support and movement guidance for the carrier 200. As shown in FIGS. 12, 15, 16 and 30, the third support portion 430 is implemented as a fifth ball 431 and a sixth ball 432.

[0178] In some optional embodiments, the third support portion 430 can be implemented as a guide rod, which has the same structure as the top guide rod 423 implemented as the second support portion 420 and extends along the direction parallel to the optical axis and is assembled between the outer frame 100 and the carrier 200 to ensure the parallelism and stability of the movement of the carrier 200.

[0179] In some specific examples, when the third support portion 430 is implemented as two balls, the corresponding abutting faces of the second side wall 120 of the outer frame 100 are recessed inwardly into the outer frame 100, and the corresponding abutting faces of the second carrier side wall 212 of the carrier 200 are recessed inwardly into the carrier 200, forming at least one pair of V-shaped guide grooves with opposite opening directions or further including a three-edge guide groove with a planar bottom surface, i.e., a slanted side wall guide groove 460. Under the action of magnetic attraction, the top wall and the bottom wall in the inner wall of the slanted side wall guide groove 460 simultaneously clamp the outer sides of the balls of the third support portion 430, avoiding the loosening or falling off of the balls of the third support portion 430.

[0180] As shown in FIG. 10, the top wall and the bottom wall in the inner wall of each pair of slanted side wall guide grooves 460 clamp the balls of the third support portion 430 from the top and bottom sides to ensure that the balls are clamped and stably move in the slanted side wall guide groove 460. The horizontal width of the slanted side wall guide groove 460 is greater than its upper and lower heights or its depth, and the third support portion 430 can have a certain movement space in the direction parallel to the pre-pressure direction, so that the carrier 200 in the inclined state has sufficient adjustment space to avoid being stuck. As shown in FIGS. 22 and 26, the bottom of the carrier 200 is provided with an auxiliary metal piece, the bottom surface of the auxiliary metal piece and the top surface of the bent section 622 of the magnetic yoke 620 clamp the balls of the third support portion 430 from the top and bottom sides, instead of each pair of slanted side wall guide grooves 460 to realize the assembly of the balls of the third support portion 430.

[0181] Specifically, the two balls constituting the same support portion are located in two pairs of slanted side wall guide grooves 460, which are arranged along the direction parallel to the optical axis but are not connected to each other, i.e., each ball is located in a pair of slanted side wall guide grooves 460 to avoid interference between the two balls.

[0182] In some specific examples, when the third support portion 430 is implemented as a guide rod, the guide rod structure is the same as the top guide rod 423 implemented as the second support portion 420, and the corresponding abutting surfaces of the second side wall 120 of the outer frame 100 and the corresponding abutting surfaces of the second carrier side wall 212 of the carrier 200 are respectively recessed downward or upward, forming an open upward or open downward U-shaped guide slot 450 to fit the guide rod. Wherein the opening of the U-shaped guide slot 450 is provided with a pressing block for pressing the guide rod to avoid the guide rod from being raised in the U-shaped guide slot 450.

[0183] In the specific examples of the present application, under the magnetic attraction of the magnetic attraction assembly 600, the first support portion 410 and the third support portion 430 are respectively clamped on both sides of the bottom of the carrier 200, that is, the magnetic attraction assembly 600 has a certain inhibitory effect on the tendency of the carrier 200 to be raised on the second carrier side wall 212. On this basis, as known from the foregoing, the smaller the inclination arm of the friction head 311 of the driving member 310 to the support assembly 400, the smaller the inclination torque, and the lower the risk of the carrier 200 being inclined.

[0184] Therefore, the present application provides another embodiment, in which the second support portion 420 is also arranged on the first side, close to the driving member 310, that is, the second support portion 420 is fitted on the top of the first side wall 110 of the outer frame 100 and the top of the first carrier side wall 211 of the carrier 200, so that the first support portion 410 and the second support portion 420 on the same side at different heights provide corresponding pre-pressure support to the carrier 200, which can eliminate the long arm and further reduce the risk of the carrier 200 being inclined. In this embodiment, the first support portion 410 is still the main support structure, and the second support portion 420 is the auxiliary support structure, that is, the first support portion 410 is tightly fitted, and the second support portion 420 is loosely fitted, to ensure that the carrier 200 always has a small inclination torque, thereby reducing the risk of the carrier 200 being inclined.

[0185] The first support portion 410 and the second support portion 420 are disposed on the same side of the driving member 310, and the first carrier side wall 211 of the carrier 200 has a longer dimension, so that the support surfaces of the first support portion 410 and the second support portion 420 on the first carrier side wall 211 of the carrier 200 have no significant difference. That is, the first support portion 410 and the second support portion 420 each have two end sides in the direction parallel to the optical axis, the distance between the two end sides of the first support portion 410 is approximately equal to the distance between the two end sides of the second support portion 420, when the first support portion 410 is implemented as a ball bearing, and the second support portion 420 is implemented as a top guide rod 423 or a ball bearing, the two end sides of the first support portion 410 are two ball bearings, and the two end sides of the second support portion 420 are two ends of the top guide rod 423 or two ball bearings, the distance between the ball bearings of the first support portion 410 is approximately equal to the effective length of the top guide rod 423 or the ball bearings of the second support portion 420. In this way, the friction head 311 and the friction contact position 213 of the carrier 200 do not need to be eccentric, that is, in the state that the pre-pressing actuating assembly 300 is not powered, the straight-line distance from the friction contact position 213 to the first support portion 410 and the straight-line distance from the friction contact position 213 to the second support portion 420 are equal, which helps to improve the stability of the carrier 200, and when the carrier 200 is driven to move in the direction of the optical axis, the action point of the friction head 311 on the carrier 200 is not easy to move out of the range of the side support surface.

[0186] In this embodiment, the second support portion 420 can be implemented as a ball bearing or a top guide rod 423. When the second support portion 420 is implemented as a ball bearing, the carrier 200 and the outer frame 100 are respectively provided with L-shaped guide grooves 440 to clamp the ball bearings of the second support portion 420 between the L-shaped guide grooves 440, as shown in FIG. 9, the openings of the L-shaped guide grooves 440 of the carrier 200 are in the pre-pressing direction, and the openings of the L-shaped guide grooves 440 of the outer frame 100 are in the opposite direction, the ball bearings of the second support portion 420 have an adjustment space perpendicular to the pre-pressing direction in the pair of L-shaped guide grooves 440, and the ball bearings of the second support portion 420 are clamped in the pair of L-shaped guide grooves 440 in the left-right direction parallel to the pre-pressing direction under the action of the pre-pressing force, so that when no pre-pressing force is applied, the carrier 200 can have left-right shaking, and the ball bearings of the second support portion 420 have the risk of falling off.

[0187] In order to avoid the second support part 420 from falling off, the second support part 420 is implemented as a top guide rod 423 as an auxiliary support of the first support part 410. The corresponding abutting surface of the first side wall 110 of the outer frame 100 and the corresponding abutting surface of the first carrier side wall 211 of the carrier 200 are respectively recessed downward or upward, forming an open upward or open downward U-shaped guide slot 450 to fit the top guide rod 423. As shown in FIGS. 14-17 and FIG. 30, the top surface of the first carrier side wall 211 of the carrier 200 is provided with a U-shaped guide slot 450, the second support part 420 is implemented as a top guide rod 423, the top guide rod 423 is arranged in the U-shaped guide slot 450, and both ends of the top guide rod 423 are fixed on the outer frame 100, so that even if no pre-pressure is applied, the carrier 200 is not easy to shake, and the top guide rod 423 will not fall off. In order to enable the top guide rod 423 to abut against the carrier 200 and reduce the gap between the top guide rod 423 and the carrier 200 due to assembly, the top of the U-shaped guide slot 450 is provided with a pressing accessory 470 for pressing the top of the carrier 200, so as to avoid the top guide rod 423 from being raised in the U-shaped guide slot 450. In an embodiment of the present application, the pressing accessory 470 is installed from top to bottom corresponding to the U-shaped guide slot 450 of the carrier 200, and has a protrusion to abut against the top guide rod 423, and the pressing accessory 470 is fixed on the outer frame 100. In some embodiments, the U-shaped guide slot 450 can also be applied to the case where the first support part 410 or the second support part 420 is implemented as a ball.

[0188] As shown in FIG. 6, the first support part 410 is arranged on the same side as the pre-pressing actuating assembly 300, that is, the driving member 310 is closer to the first support part 410 with larger ball-to-ball distance in the setting position, so that on the one hand, the space utilization is more reasonable, because the driving member 310 and the pre-pressing member 320 are both extended along the optical axis direction, and the side wall of the carrier 200 located on the first side also needs to be extended along the optical axis direction, that is, the first carrier side wall 211 of the carrier 200 needs to have a certain length, and the first support part 410 is arranged on the bottom surface of the first carrier side wall 211 of the carrier 200, so that the first support part 410 can have longer space to arrange the two balls. On the contrary, the second carrier side wall 212 of the carrier 200 does not need to arrange the driving member 310, and can be arranged shorter to accommodate the second support part 420 and the third support part 430. In this way, not only can the structure of the periscope camera module be more compact, but also it is beneficial to reduce the size of the periscope camera module. On the other hand, because the optical focusing stroke in the periscope camera module is large, this design is also helpful for the balls to support the carrier 200 throughout the long stroke.

[0189] Since the pre-press actuating assembly 300 exerts pressure on the friction plate 214 in actual operation, the longer the length of the friction plate 214, the longer the driving stroke of the corresponding driving member 310, and the longer the length of the first carrier side wall 211 of the carrier 200. Preferably, the length of the second carrier side wall 212 of the carrier 200 is shorter than the length of the first carrier side wall 211, and only the balls are arranged on the second carrier side wall 212 of the carrier 200, the distance between the balls can be adjusted, and as long as the distance between the two balls of the first support part 410 is large enough, the overall structure balance can be met. Therefore, the second carrier side wall 212 of the carrier 200 does not need to be lengthened to have the same length as the first carrier side wall 211.

[0190] More specifically, when the first support part 410 and the second support part 420 are implemented as two balls, the ball spacing between the two balls of the first support part 410 is not less than the ball spacing of the second support part 420, and the greater the distance between the two balls in the optical axis direction, the more stable the support of the carrier 200.

[0191] In some optional embodiments, as shown in FIG. 12, FIG. 13, FIG. 28 and FIG. 30, the ball spacing between the two balls of the first support portion 410 is greater than the ball spacing between the two balls of the second support portion 420, preferably 1.5 times or more. Further, in some optional embodiments, the spacing between the two L-shaped guide slots 440 clamping the first support portion 410 is 1.5 times or more than the spacing between the two L-shaped guide slots 440 or U-shaped guide slots 450 clamping the second support portion 420, wherein the ball spacing and all guide slot spacings are the spacings in the direction parallel to the optical axis. When the first support portion 410 and the driving member 310 are disposed on the same side of the first side, and the second support portion 420 is disposed on the second side, the first support portion 410 is disposed at the bottom of the first carrier sidewall 211 of the carrier 200, and the second support portion 420 is disposed at the top of the second carrier sidewall 212 of the carrier 200, and the first support portion 410 and the second support portion 420 are symmetrically disposed relative to the optical axis in the height direction, and the friction contact position 213 of the friction head 311 of the driving member 310 and the carrier 200 is located on the first carrier sidewall 211 of the carrier 200, closer to the first support portion 410. Because the ball spacing between the two balls of the first support portion 410 is large, the first support portion 410 provides a larger support range for the carrier 200, and the friction contact position 213 of the friction head 311 and the carrier 200 is less likely to move out of the support range provided by the first support portion 410 when the carrier 200 is driven to move in the direction of the optical axis, so that the carrier 200 is more stably supported, and the carrier 200 is supported in the height direction, effectively preventing the carrier 200 from tilting or overturning. When the first support portion 410, the second support portion 420 and the driving member 310 are disposed on the same side, the four balls of the first support portion 410 and the second support portion 420 form a side support surface on the first carrier sidewall 211 of the carrier 200. Compared with the part of the embodiment in which the ball spacing of the first support portion 410 and the second support portion 420 is the same, the larger the ball spacing of the first support portion 410, the larger the coverage range of the side support surface, and the larger the coverage value interval in the direction parallel to the optical axis, so that the friction contact point (i.e., the contact position 213) of the friction head 311 of the driving member 310 on the first carrier sidewall 211 of the carrier 200 is always located within the side support surface, avoiding the contact position 213 moving out of the side support surface during the movement of the carrier 200, resulting in insufficient support of the carrier 200 in the pre-pressing direction, thereby causing the carrier 200 to tilt.

[0192] Further, in the state that the driving member 310 is not energized, the contact position 213 between the friction head 311 of the driving member 310 and the carrier 200 is arranged close to the first support part 410, that is, in the state that the driving member 310 is not energized, the straight line distance from the friction contact position 213 to the second support part 420 is greater than the straight line distance from the friction contact position 213 to the first support part 410, in other words, the height of the friction head 311 of the driving member 310 is arranged as close to the first support part 410 as possible. Since the ball pitch of the first support part 410 is greater than the ball pitch of the second support part 420, the closer the height of the friction head 311 to the first support part 410, the wider the range covered by the side surface support surface, the less likely the action point of the friction head 311 on the carrier 200 moves out of the side surface support surface, the better the support effect on the carrier 200, and the more likely the action point of the friction head 311 on the carrier 200 remains within the range of the ball support, thereby avoiding the inclination of the carrier 200 as much as possible.

[0193] More specifically, when the carrier 200 moves along the optical axis direction, the magnetic attracting magnet 610 also moves with the movement of the carrier 200, and the action point of the corresponding magnetic attraction force on the carrier 200 also moves, and the first support part 410 and the third support part 430 each have two end sides in parallel to the optical axis direction, the distance between the two end sides of the first support part 410 is not less than the distance between the two end sides of the third support part 430, when the first support part 410 and the third support part 430 are implemented as two balls, the two end sides of the first support part 410 and the third support part 430 are each two balls, and the ball pitch between the two balls of the two balls of the first support part 410 is not less than the ball pitch of the third support part 430. If the distance between the two balls of the first support part 410 is equal to the distance between the two balls of the third support part 430, the first support part 410 and the third support part 430 form a nearly rectangular ball support surface, and when the carrier 200 is driven to move along the optical axis direction, the action point of the magnetic attraction force on the carrier 200 has the risk of moving out of the ball support surface, and if the action point of the magnetic attraction force moves out of the range of the ball support surface, a moment is generated, which easily causes the carrier 200 to incline or overturn, (the straight line distance from the action point of the magnetic attraction force to the line connecting the two balls in the width direction is the force arm), and thus the action point of the magnetic attraction force needs to be kept within the range of the ball support surface.

[0194] Preferably, as shown in FIG. 12, FIG. 15, FIG. 28 and FIG. 30, the ball spacing between the two balls of the first support portion 410 is greater than the ball spacing between the two balls of the third support portion 430, preferably 1.5 times or more in some preferred embodiments. Further, in some optional embodiments, the spacing between the two L-shaped guide grooves 440 clamping the first support portion 410 is 1.5 times or more than the spacing between the two inclined sidewall guide grooves 460 clamping the third support portion 430, wherein the above-mentioned ball spacing and all guide groove spacings are the spacings in the direction parallel to the optical axis. The four balls between the first support portion 410 and the third support portion 430 form a magnetic attraction support surface on the bottom surface of the carrier 200, and the ball spacing of the first support portion 410 is greater than that of the third support portion 430. On the one hand, the area of the magnetic attraction support surface is increased, so that the magnetic attraction of the magnetic assembly 600 to the bottom surface of the carrier 200 is always located in the magnetic attraction support surface, so that the carrier 200 is supported more stably, avoiding the carrier 200 from being separated or tilted during movement or falling; on the other hand, the magnetic attraction force generated between the magnetic magnet 610 and the magnetic yoke 620 clamps the first support portion 410 and the third support portion 430 between the bottom surface of the carrier 200 and the middle top surface of the outer frame 100, so that the carrier 200 is always supported, reducing the risk of magnetic attraction and corresponding support failure of the carrier 200, and reducing the probability of the carrier 200 tilting caused thereby. Further, the magnetic assembly 600 is arranged near the bottom of the carrier 200 close to the first support portion 410, so as to ensure that the magnetic force acting point is always located in the magnetic attraction support surface, avoiding the carrier 200 from tilting.

[0195] Further, by arranging the magnetic magnet 610 close to the first support portion 410, the magnetic force acting point can be more effectively prevented from moving out of the range of the magnetic attraction support surface, and the carrier 200 can be more effectively prevented from tilting.

[0196] In some preferred embodiments, in the state that the driving member 310 is not energized, when the second support portion 420 is arranged on the second side, the straight-line distance from the second support portion 420 to the driving member 310 is not equal to the straight-line distance from the third support portion 430 to the driving member 310, i.e., the second support portion 420 and the third support portion 430 are not located in the same height direction, so as to provide more stable support for the carrier 200.

[0197] In an embodiment of the present application, the number of the magnetic magnet 610 is one, and the bottom of the carrier 200 is provided with a groove for accommodating the magnetic magnet 610. The magnetic magnet 610 is arranged in the groove on the bottom surface of the carrier 200, and at least a part of the magnetic magnet 610 is exposed to generate a magnetic attraction force opposite to the magnetic yoke 620 of the outer frame 100.

[0198] The magnetic attraction magnet 610 is arranged close to the first support part 410, as shown in FIG. 35, the distance from the magnetic attraction magnet 610 to the first support part 410 is less than the distance from the magnetic attraction magnet 610 to the second support part 420, and the magnetic attraction magnet 610 is arranged closer to the first support part 410 with larger ball spacing between the two balls of the first support part 410 and the two balls of the second support part 420, that is, the first support part 410 has larger ball spacing, and the first support part 410 and the second support part 420 form a nearly right trapezoidal ball support surface, so that the support area of the ball close to the first support part 410 is larger, and when the carrier 200 is driven to move along the optical axis direction, the action point of the magnetic attraction force on the carrier 200 can be located in the larger size ball support surface, and the magnetic attraction force action point is more avoided to move out of the range of the ball support surface, and the carrier 200 is more avoided to be tilted.

[0199] In another embodiment of the present application, the number of magnetic attraction magnets 610 is two, and the two magnetic attraction magnets 610 are symmetrically arranged relative to the optical axis at the bottom of the carrier 200, so that the action point of the magnetic attraction force can be located at the midpoint of the line connecting the two magnetic attraction magnets 610. In the nearly right trapezoidal ball support surface formed by the first support part 410 and the third support part 430, the magnetic attraction force can move towards or away from the hypotenuse of the right trapezoid, and the action point of the magnetic attraction force on the carrier 200 can have a larger moving space without exceeding the range of the ball support surface, thereby avoiding the carrier 200 from being tilted.

[0200] In some embodiments of the present application, the first support part 410, the second support part 420 and the third support part 430 are all implemented as two balls arranged along the optical axis direction.

[0201] In one embodiment, the ball size of the third support part 430 is equal to the ball size of the first support part 410, and since the first support part 410 and the third support part 430 are arranged opposite at the bottom of the carrier 200, the balls with the same size can make the carrier 200 be more stably supported at the bottom, and further reduce the generation of the carrier 200 tilt.

[0202] In an embodiment of the present application, the ball size of the second support portion 420 is smaller than the ball size of the first support portion 410 and the third support portion 430. It should be understood that the balls of the first support portion 410 and the third support portion 430 are located at the bottom of the carrier 200, and the balls of the second support portion 420 are located at the top of the carrier 200. Such an arrangement makes the balls of the first support portion 410 and the third support portion 430, which are arranged between the bottom of the first side wall 110 of the outer frame 100 and the bottom of the first carrier side wall 211 of the carrier 200 and between the bottom of the second side wall 120 of the outer frame 100 and the bottom of the second carrier side wall 212 of the carrier 200, respectively, bear a greater force and be more likely to produce dents when the periscope camera module falls or is impacted.

[0203] Further, since the first support portion 410 and the third support portion 430 are arranged in close fit in the direction of the magnetic force, that is, the upper and lower sides of the balls of the first support portion 410 and the third support portion 430 abut against the ball grooves (the balls of the first support portion 410 abut against the L-shaped guide groove 440, and the balls of the third support portion 430 abut against the inclined side wall guide groove 460), and the second support portion 420 is arranged in loose fit, that is, at least one side of the balls of the second support portion 420 has a gap with the ball groove (that is, the L-shaped guide groove 440), to alleviate the impact on the balls of the second support portion 420, the balls of the first support portion 410 and the third support portion 430 bear a greater force and are more likely to produce dents when the periscope camera module falls or is impacted.

[0204] Specifically, the balls of the first support portion 410 and the third support portion 430 are designed to be larger in size, which can disperse the force on the balls of the first support portion 410 and the third support portion 430 when impacted, and reduce the degree of dents of the first support portion 410 and the third support portion 430.

[0205] In an embodiment of the present application, the diameter of the balls of the first support portion 410 is 1 mm, and the diameter of the balls of the second support portion 420 is 0.8 mm. As shown in FIGS. 6, 8, 12, 13, 22, and 34, the L-shaped guide groove 440 accommodating the balls of the second support portion 420 is recessed inward and downward from the top of the carrier 200. The smaller diameter of the balls of the second support portion 420 can reduce the thickness of the side wall of the second side of the carrier 200, that is, the thickness of the first carrier side wall 211 of the carrier 200, thereby achieving the reduction of the width dimension of the periscope camera module.

[0206] In other embodiments, the ball size of the second support portion 420 can also be equal to the ball size of the first support portion 410.

[0207] Therefore, in the present application, the ball size of the first support part 410 and the third support part 430 is designed to be larger, so as to disperse the force when the first support part 410 and the third support part 430 are impacted, and reduce the occurrence of dents of the first support part 410 and the third support part 430.

[0208] In the specific examples of the present application, the pre-press actuating assembly 300 includes a driving piece 310 and a pre-press piece 320 arranged on the first side wall 110 of the outer frame body 100, the driving piece 310 is located between the pre-press piece 320 and the first carrier side wall 211 of the carrier 200, and the pre-press piece 320 applies a pre-press force to the driving piece 310 perpendicular to the first carrier side wall 211 of the carrier 200, so as to abut against the first carrier side wall 211 of the carrier 200, thereby achieving the side driving of the carrier 200 by the pre-press actuating assembly 300. In order to sense the actual motion position of the carrier 200 in real time and better cooperate with the driving of the carrier 200 by the driving piece 310, the periscopic camera module further includes a position sensing assembly 800, which includes a position sensing element 810 and a position sensing magnet 820. As shown in FIGS. 6 and 13, the position sensing element 810 is arranged on the second side wall 120 of the outer frame body 100 and is arranged opposite to the pre-press actuating assembly 300, and the position sensing magnet 820 is arranged on the second carrier side wall 212 of the carrier 200 at a position corresponding to the position sensing element 810. As shown in FIGS. 6, 13, 16, 17, 29 and 30, the second carrier side wall 212 of the carrier 200 is provided with a sensing magnet groove 216 for mounting the position sensing magnet 820.

[0209] In some specific embodiments, the driving piece 310 includes a piezoelectric vibrator 312 and a friction head 311 arranged on the side of the piezoelectric vibrator 312 facing the carrier 200. As shown in FIGS. 6, 11, 13 and 37, the friction head 311 and the pre-press piece 320 are respectively located on the two sides of the piezoelectric vibrator 312, the friction head 311 abuts against the first carrier side wall 211 of the carrier 200 through the pre-press piece 320, the piezoelectric vibrator 312 makes the friction head 311 and the carrier 200 frictionally connected through its own vibration or piezoelectric actuation, and drives the carrier 200 to move.

[0210] Specifically, the piezoelectric vibrator 312 is a substrate with a reverse piezoelectric effect and shrinks or expands according to the polarization direction and the electric field direction, which can be used by polarizing the substrate in the thickness direction of a single crystal, polycrystalline ceramic, polymer, etc. The reverse piezoelectric effect refers to the mechanical deformation of a dielectric when an electric field is applied in the polarization direction of the dielectric when a potential difference is generated. The piezoelectric vibrator 312 has the function of ultrasonic oscillation, that is, it realizes a pendulum reciprocating motion or an elliptical motion on a specifically arranged electrode layer, so as to drive the friction head 311 to perform a pendulum reciprocating motion or an elliptical motion, and then realize the movement of the carrier 200 relative to the outer frame 100 through the friction between the friction head 311 and the outer side wall of the carrier 200.

[0211] In some specific examples, the piezoelectric vibrator 312 is arranged on the first side wall 110 of the outer frame 100 along the direction extending parallel to the optical axis, and the friction head 311 is protrudingly arranged on the side of the piezoelectric vibrator 312 facing the carrier 200. The number of friction heads 311 can be one, two or more. Under the vibration or piezoelectric actuation of the piezoelectric vibrator 312, the friction head 311 is in contact with the first carrier side wall 211 of the carrier 200 and drives the carrier 200 to move.

[0212] Preferably, the friction head 311 is implemented as two friction heads 311 arranged at intervals along the extension direction of the piezoelectric vibrator 312 or along the optical axis. The two friction heads 311 can cooperate with each other to drive the long-stroke movement of the carrier 200. Further, the arrangement position of the friction head 311 on the piezoelectric vibrator 312 can cooperate with the mode of the piezoelectric vibrator 312. The piezoelectric vibrator 312 bends and vibrates or piezoelectric actuates in a mode of one wave peak and one wave trough in the thickness direction thereof. The friction head 311 is arranged at the corresponding position of the wave peak and the wave trough, which increases the friction between the friction head 311 and the carrier 200, so as to improve the driving effect on the carrier 200.

[0213] In some specific examples, the friction head 311 and the piezoelectric vibrator 312 can be implemented as an integrated structure or a detachable structure. The friction head 311 can be fixed on the piezoelectric vibrator 312 by means of bonding, clamping, nesting, welding or fastener connection, etc. More specifically, the connection between the friction head 311 and the piezoelectric vibrator 312 is a surface connection to ensure the connection strength, and the friction head 311 can move with the deformation of the piezoelectric vibrator 312.

[0214] In some specific examples, the friction head 311 is made of wear-resistant materials, such as various high-hardness wear-resistant ceramic materials, such as alumina, zirconium oxide, silicon carbide ceramics, or high wear-resistant metal materials, carbon fiber materials, or composite materials of ceramics, metal particles and polymers, etc., in order to improve the wear resistance of the friction head 311, which is beneficial to improve the friction between the carrier 200 and the friction head 311, which is beneficial to improve the driving efficiency, and due to the wear resistance, it is beneficial to extend the service life of the friction head 311.

[0215] In some specific examples, to improve the driving performance of the pre-pressurized actuation component 300, the piezoelectric oscillator 312 can be made of piezoelectric ceramic material or piezoelectric single crystal material. The piezoelectric oscillator 312 can be a single-layer ceramic body or a single-layer single crystal, or it can be a multi-layer ceramic body or a multi-layer single crystal, such as lead zirconate titanate (PZT) based piezoelectric ceramics, potassium sodium niobate (KNN) based piezoelectric ceramics, barium titanate (BT) based piezoelectric ceramics, lead magnesium niobate-lead indium niobate (PMN-PT) based piezoelectric single crystals, etc.

[0216] In a specific example of this application, the preload member 320 applies a preload towards the carrier 200 to the drive member 310, so that the friction head 311 of the drive member 310 always maintains frictional contact with the first carrier sidewall 211 of the carrier 200. Since the piezoelectric vibrator 312 undergoes mechanical deformation during drive, the preload member 320 has an elastically deformable portion (elastic portion 3212) for abutting against the piezoelectric vibrator 312 and a fixing portion 3211 for mounting the piezoelectric vibrator 312, so as to fix the piezoelectric vibrator 312 and apply a preload towards the carrier 200 to the drive member 310, thereby maintaining frictional contact between the friction head 311 and the carrier 200.

[0217] In some specific embodiments, as shown in FIG2, the preload 320 is implemented as a spring sheet 321 extending in a direction parallel to the optical axis. The spring sheet 321 assembles the piezoelectric vibrator 312 onto the first sidewall 110 of the outer frame 100. The spring sheet 321 has a first fixed end 32111, a second fixed end 32112, and a third fixed end 32113 distributed in a direction parallel to the optical axis. A first elastic portion 32121 is provided between the first fixed end 32111 and the second fixed end 32112. A second elastic portion 32122 is provided between the second fixed end 32112 and the third fixed end 32113. The first fixed end 32111, the second fixed end 32112, and the third fixed end 32113 are fixed to the first side wall 110 of the outer frame 100 by welding, riveting, or bonding. The first elastic portion 32121 and the second elastic portion 32122 both extend parallel to the optical axis to connect adjacent fixed ends and apply appropriate preload to the drive member 310 by utilizing their own elastic deformation properties. In some optional embodiments, the preload member 320 can also be implemented as an elastic adhesive.

[0218] More specifically, the pre-pressing member 320 comprises the elastic sheet 321 and at least one clamping sheet 322 extending from the elastic sheet 321 towards the carrier 200, as shown in FIGS. 6, 11 and 37. The clamping sheet 322 is connected to the second fixed end 32112 of the elastic sheet 321 on one side, and has a first clamping arm and a second clamping arm on the side facing the carrier 200. The first clamping arm and the second clamping arm extend towards the carrier 200 in a direction perpendicular to the optical axis, and are used to clamp the piezoelectric vibrator 312 to ensure the stability of the installation.

[0219] In this embodiment, since the piezoelectric vibrator 312 drives the friction head 311 through its bending vibration or piezoelectric actuation, the larger the extension size of the clamping arm, the larger the overlapping area between the piezoelectric vibrator 312 and the clamping arm of the clamping sheet 322, and the greater the influence on the vibration or piezoelectric actuation of the piezoelectric vibrator 312. Therefore, the size of the clamping arm of the clamping sheet 322 should not be greater than 1 / 2 of the length of the side wall of the piezoelectric vibrator 312 (i.e. the length in the direction of the optical axis), so as to avoid the clamping arm of the clamping sheet 322 clamping too tightly or the overlapping area between the clamping arm and the piezoelectric vibrator 312 being too large, which causes the vibration or piezoelectric actuation of the piezoelectric vibrator 312 to be inhibited.

[0220] In some embodiments, the elastic sheet 321 is implemented as a planar elastic sheet, and can also be implemented as an elastic sheet 321 with a bending structure.

[0221] In some alternative embodiments, the elastic sheet 321 comprises at least two fixed parts 3211 arranged on the first side wall 110 of the outer frame 100 and an elastic part 3212 connecting the adjacent two fixed parts 3211, as shown in FIGS. 18 and 19. The fixed part 3211 comprises a first fixed part 32114 and a second fixed part 32115 fixed to the first side wall 110 of the outer frame 100. The first fixed part 32114 and the second fixed part 32115 can be fixed to the outer side of the first side wall 110 of the outer frame 100 by welding, riveting or bonding. The elastic part 3212 extends in a direction parallel to the optical axis and has a bending part 3213 facing the piezoelectric vibrator 312, so as to apply a pre-pressing force to the friction head 311 on the piezoelectric vibrator 312 to abut against the carrier 200.

[0222] Further, the piezoelectric vibrator 312 is provided with a conductive assembly 700, which is assembled between the piezoelectric vibrator 312 and the elastic part 3212, so as to facilitate the assembly and driving of the driving member 310.

[0223] In some embodiments, the elastic part 3212 covers the side of the piezoelectric vibrator 312 away from the carrier 200 in the pre-pressure direction, i.e. perpendicular to the optical axis direction, so that at least a part of the elastic part 3212 overlaps with the side of the piezoelectric vibrator 312 away from the carrier 200, so that the side of the piezoelectric vibrator 312 is supported by the elastic part 3212, not only to keep the piezoelectric vibrator 312 in a flat plane, but also to avoid uneven pre-pressure. The area of the elastic part 3212 is not less than the area of the side of the piezoelectric vibrator 312 away from the carrier 200.

[0224] Specifically, the elastic part 3212 includes a bonding part and a deformation part. The bonding part overlaps with the side of the piezoelectric vibrator 312 away from the carrier 200 in the direction perpendicular to the optical axis direction, so as to fix the piezoelectric vibrator 312 to the elastic part 3212. The deformation part does not overlap with the side of the piezoelectric vibrator 312 away from the carrier 200, so as to generate elastic deformation to generate pre-pressure on the driving part 310. The arrangement of the elastic part 3212 makes the actual motion state of the piezoelectric vibrator 312 of the driving part 310 closer to the design value, reduces the influence of the external environment on the piezoelectric vibrator 312, and also prevents the vibration or piezoelectric actuation of the piezoelectric vibrator 312 from being transmitted to the outer frame body 100, causing the vibration or piezoelectric actuation of the outer frame body 100.

[0225] Specifically, the elastic part 3212 includes a bonding part and a deformation part. The bonding part overlaps with the side of the piezoelectric vibrator 312 away from the carrier 200 in the direction perpendicular to the optical axis direction, so as to fix the piezoelectric vibrator 312 to the elastic part 3212. The deformation part does not overlap with the side of the piezoelectric vibrator 312 away from the carrier 200, so as to generate elastic deformation to generate pre-pressure on the driving part 310. The arrangement of the elastic part 3212 makes the actual motion state of the piezoelectric vibrator 312 of the driving part 310 closer to the design value, reduces the influence of the external environment on the piezoelectric vibrator 312, and also prevents the vibration or piezoelectric actuation of the piezoelectric vibrator 312 from being transmitted to the outer frame body 100, causing the vibration or piezoelectric actuation of the outer frame body 100.

[0226] Further, according to the formula: K = F / X, where K is the stiffness (or elastic coefficient), F is the elastic force, and X is the displacement of deformation, reducing the K value of the elastic part 3212 actually reduces the sensitivity of the elastic force to the displacement. When the K value of the elastic part 3212 is smaller, the fluctuation of the elastic force caused by the fluctuation of the displacement will be smaller, that is, the fluctuation of the pre-pressure of the elastic part 3212 acting on the driving part 310 will be smaller, and thus the friction between the friction head 311 and the carrier 200 is more uniform and consistent.

[0227] Specifically, as shown in FIGS. 18 and 19, the deformation part of the elastic part 3212 has a hollow structure 32123 to reduce the thickness of the deformation part. The thinner the material of the deformation part, the smaller the K value of the elastic part 3212, so that the deformation part of the elastic part 3212 is more suitable for the bending vibration or piezoelectric actuation of the piezoelectric vibrator 312. The longer the extension length of the deformation part along the length direction of the first side wall 110 of the outer frame body 100, the smaller the K value (stiffness or elastic coefficient) of the elastic part 3212, and the easier the elastic deformation.

[0228] Wherein, the K value of the elastic part 3212 is smaller, that is, the deformation occurs, thereby reducing the pre-pressing force change caused by the material tolerance and the assembly tolerance in the contact system composed of the carrier 200, the driving part 310 and the elastic part 3212, thereby improving the consistency of the pre-pressing actuating assembly 300.

[0229] Specifically, the pre-pressing force provided by the elastic part 3212 of the pre-pressing part 320 is transmitted to the piezoelectric vibrator 312 of the driving part 310, so that the friction head 311 located on the piezoelectric vibrator 312 abuts against the carrier 200. Due to the smaller K value, the elastic part 3212 will be deformed to different degrees due to the tolerance, thereby reducing the pre-pressing force difference of the pre-pressing actuating assembly 300 under different tolerances.

[0230] Further, in some embodiments, the bending part 3213 makes the fixing part 3211 and the elastic part 3212 located in different planes, that is, the plane where the fixing part 3211 is located and the plane where the elastic part 3212 is located are parallel to each other and have a certain distance, so that the fixing part 3211 is fixedly connected to the first side wall 110 of the outer frame body 100, and the elastic part 3212 is arranged on the side of the piezoelectric vibrator 312 away from the carrier 200, so as to apply a pre-pressing force in the direction perpendicular to the optical axis to the piezoelectric vibrator 312, thereby realizing the frictional contact between the friction head 311 and the carrier 200. Compared with the design of the planar elastic sheet 321 in which the fixing part 3211 and the elastic part 3212 are located in the same plane, the presence of the bending part 3213 can also reduce the K value of the elastic part 3212, so as to reduce the fluctuation of the pre-pressing force of the elastic part 3212 acting on the driving part 310, and further make the friction force between the friction head 311 and the carrier 200 more uniform and consistent.

[0231] Wherein, since the elastic part 3212 is connected with the first fixing part 32114 and the second fixing part 32115, the number of the bending part 3213 is also two, including the first bending part 32131 and the second bending part 32132, the first bending part 32131 connects the first fixing part 32114 and the elastic part 3212, and the second bending part 32132 connects the second fixing part 32115 and the elastic part 3212.

[0232] In some embodiments, referring to FIG. 20, the bending part 3213 connects the fixing part 3211 and the elastic part 3212 obliquely, and the plane where the bending part 3213 is located intersects the plane where the fixing part 3211 is located and the plane where the elastic part 3212 is located.

[0233] Specifically, the first bending part 32131 and the second bending part 32132 are connected to the first fixed part 32114, the elastic part 3212 and the second fixed part 32115 in opposite inclined directions, so that the pre-pressing part has an opening with gradually increasing size extending outward from the elastic part 3212, i.e. the extension line of the first bending part 32131 intersects with the extension line of the second bending part 32132. In the pre-pressing part, the elastic part 3212 protrudes outward from the fixed part 3211, i.e. the distance from the plane where the elastic part 3212 is located to the carrier 200 is greater than the distance from the plane where the fixed part 3211 is located to the carrier 200, so that when the fixed part 3211 is fixedly connected to the first side wall 110 of the outer frame body 100, the elastic part 3212 is tightly pressed against the side of the piezoelectric vibrator 312 away from the carrier 200 to generate a certain pre-pressing force on the driving member 310. Moreover, the K value of the elastic part 3212 can be reduced to make the fluctuation of the pre-pressing force of the elastic part 3212 on the driving member 310 smaller, and thus make the friction force between the friction head 311 and the carrier 200 more uniform and consistent.

[0234] In some alternative embodiments, the pre-pressing member 320 can be implemented as an integrated structure, i.e. the fixed part 3211 and the elastic part 3212 are integrally formed, and the bending part 3213 is once stamped at the connection position of the fixed part 3211 and the elastic part 3212 to improve the consistency of the pre-pressing member 320. In some alternative embodiments, the pre-pressing member 320 can also be implemented as a split structure, i.e. the fixed part 3211, the elastic part 3212 and the bending part 3213 are separately manufactured, and then connected to be integrated through bonding or welding, etc. to simplify the manufacturing of the pre-pressing member 320.

[0235] In some alternative embodiments, the pre-pressing member 320 can be implemented to include a buffer member 323 and a structural member 324, as shown in FIG. 36. The structural member 324 is connected to the first side wall 110 of the outer frame body 100 and fixes the buffer member 323 on the first side wall 110 of the outer frame body 100. One side of the buffer member 323 is connected to the driving member 310, i.e. the buffer member 323 is mounted on the first side wall 110 of the outer frame body 100 through the structural member 324. The buffer member 323 is arranged between the driving member 310 and the first side wall 110 of the outer frame body 100, or arranged between the driving member 310 and the structural member 324, and is adapted to be deformed by the extrusion of the first side wall 110 of the outer frame body 100 and the driving member 310, for applying a pre-pressing force on the driving member 310, so that the friction head 311 of the driving member 310 abuts against the first carrier side wall 211 of the carrier 200, and thus the driving member 310 is adapted to drive the carrier 200 to move relative to the outer frame body 100 when receiving a driving signal.

[0236] The first sidewall 110 of the outer frame 100 is provided with an opening penetrating the first sidewall 110 for mounting the pre-press actuating assembly 300, the structural member 324 is arranged on the side of the opening facing outward, and the size of the structural member 324 is not less than the opening. One side surface of the buffer member 323 is connected to one side surface of the structural member 324 facing the first sidewall 110 of the outer frame 100, and the other side surface of the buffer member 323 is connected to the piezoelectric vibrator 312 of the driving member 310, that is, the buffer member 323 is attached to the first sidewall 110 of the outer frame 100 and the piezoelectric vibrator 312 of the driving member 310 on both sides.

[0237] More specifically, the buffer member 323 can be implemented as a tape that does not need to be cured and can directly attach the driving member 310 to the structural member 324, and the tape also has high flatness, so that the piezoelectric vibrator 312 of the driving member 310 directly attached to the structural member 324 by the buffer member 323 has good parallelism with the structural member 324. In this way, the use of high elastic modulus glue is also avoided, for example, when using UV glue, the elastic modulus of the UV glue after curing is large, which is not suitable for being arranged between the structural member 324 and the driving member 310.

[0238] It is worth mentioning that the size of the buffer member 323 can be smaller than, equal to, or greater than the size of the piezoelectric vibrator 312 of the driving member 310. In one example, the size of the buffer member 323 is equal to or greater than the size of the piezoelectric vibrator 312 of the driving member 310, so that the piezoelectric vibrator 312 of the driving member 310 and the structural member 324 can be completely filled with the buffer member 323, thereby facilitating the guarantee of the parallelism of the piezoelectric vibrator 312 of the driving member 310 relative to the structural member 324.

[0239] It can be understood that the buffer member 323 can be arranged between the elastic sheet 321 and the piezoelectric vibrator 312, as shown in FIGS. 3 and 4, the two surfaces of the buffer member 323 are attached to the side surfaces of the elastic sheet 321 and the piezoelectric vibrator 312 to connect the two without significantly increasing the overall thickness of the pre-press actuating assembly 300.

[0240] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above examples, and the above examples and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
