Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a camera module and electronic equipment. Background Art

[0002] In related technologies, periscope anti-shake technology is achieved by rotating the prism along two axes. The anti-shake function is integrated into the entire prism. Conventional prisms adjust the angle of the reflective part by changing the angle of the prism itself to achieve the correction of the light emission direction. Specifically, Figure 20 As shown, the lens module 1' includes a prism 11', as shown in FIG. Figure 21 、 Figure 22 and Figure 23 As shown, when the incident light 3' deflects in the direction of the arrow, the prism 11' rotates as a whole to change the angle of the inclined surface, thereby adjusting the deflection angle of the outgoing light 4'. Therefore, in the related art, the entire prism is driven to rotate. Due to the large driving weight, the driving power consumption will also increase, and the driving precision control will become more difficult. In addition, as the prism anti-shake angle increases, the gap reserved for the prism movement in the module becomes larger. After the module is powered off, the shaking of the phone will cause the prism to collide with other structural parts and produce abnormal noise. Utility Model Content

[0003] The present application aims to provide a camera module and electronic equipment that at least solves one of the problems of excessive space required for the prism to rotate and high power consumption of the prism drive.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In the first aspect, an embodiment of the present application proposes a camera module, comprising: a prism assembly, the prism assembly comprising a bracket, a first transmission part, a second transmission part and a reflection part, the first transmission part and the second transmission part are arranged on the bracket, the reflection part is located between the first transmission part and the second transmission part and is movably connected to the bracket, and light enters the prism assembly from the first transmission part, is reflected by the reflection part to the second transmission part, and then exits the prism assembly; multiple driving mechanisms, the driving mechanisms are arranged on the bracket and connected to the reflection part, and the multiple driving mechanisms are used to drive the reflection part to rotate around at least one of the first direction and the second direction.

[0006] In a second aspect, an embodiment of the present application proposes an electronic device, including a shell with a light-through hole provided on the shell; such as the camera module proposed in the first aspect, the camera module is arranged in the shell and arranged opposite to the light-through hole.

[0007] In an embodiment of the present application, a camera module includes a prism assembly and multiple drive mechanisms. The prism assembly includes a bracket, a first transmissive portion, a second transmissive portion, and a reflective portion. The first and second transmissive portions are disposed on the bracket, with the reflective portion positioned between the first and second transmissive portions and movably connected to the bracket. Light enters the prism assembly through the first transmissive portion, is reflected by the reflective portion to the second transmissive portion, and then exits the prism assembly. Multiple drive mechanisms are disposed on the bracket and connected to the reflective portion, and are configured to drive the reflective portion to rotate about at least one of a first direction and a second direction. Thus, the drive mechanisms of the present application can drive the reflective portion to rotate. When the camera module experiences jitter, the drive mechanisms change the angle of the reflective portion, thereby adjusting the light emission angle, thereby compensating for light deviation caused by jitter. The drive mechanisms of the present application only drive the reflective portion of the prism assembly. The reflective portion weighs much less than the prism assembly, reducing the power consumption of the drive mechanism and improving the driving accuracy of the drive mechanism. Furthermore, the prism assembly will not shake even after power is removed. At the same time, by driving the reflective part to achieve anti-shake of the camera module, there is no need to rotate the entire prism assembly, and there is no need to set up the space required for the overall movement of the prism assembly. Therefore, the size of the camera module is reduced, which is conducive to the lightweight design of the electronic equipment.

[0041] The following combination Figures 1-19 Describe the camera module and electronic device according to the embodiments of the present application.

[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, the camera module 1 according to some embodiments of the present application includes: a prism assembly 11, the prism assembly 11 includes a bracket 111, a first transmission part 112, a second transmission part 113 and a reflection part 114, the first transmission part 112 and the second transmission part 113 are arranged on the bracket 111, the reflection part 114 is located between the first transmission part 112 and the second transmission part 113 and is movably connected to the bracket 111, and the light enters the prism assembly 11 from the first transmission part 112, is reflected by the reflection part 114 to the second transmission part 113, and then is emitted from the prism assembly 11; a plurality of driving mechanisms 12, the driving mechanisms 12 are arranged on the bracket 111 and connected to the reflection part 114, and the plurality of driving mechanisms 12 are used to drive the reflection part 114 to rotate around at least one of the first direction and the second direction.

[0043] According to an embodiment of the present application, the camera module 1 includes a prism assembly 11 and a plurality of driving mechanisms 12. The prism assembly 11 includes a bracket 111, a first transmissive portion 112, a second transmissive portion 113, and a reflective portion 114. The first transmissive portion 112 and the second transmissive portion 113 are disposed on the bracket 111. The reflective portion 114 is located between the first transmissive portion 112 and the second transmissive portion 113, and is movably connected to the bracket 111. Light enters the prism assembly 11 through the first transmissive portion 112, is reflected by the reflective portion 114 to the second transmissive portion 113, and then exits the prism assembly 11. The plurality of driving mechanisms 12 are disposed on the bracket 111 and connected to the reflective portion 114. The plurality of driving mechanisms 12 are configured to drive the reflective portion 114 to rotate about at least one of a first direction and a second direction. It can be seen that the driving mechanism 12 in the present application can drive the reflecting part 114 to rotate. When the camera module 1 shakes, the driving mechanism 12 changes the angle of the reflecting part 114, and then adjusts the emission angle of the light, thereby compensating for the light deviation that occurs when the camera module 1 shakes. The driving mechanism 12 of the present application only drives the reflecting part 114 of the prism assembly 11 to rotate. The weight of the reflecting part 114 is much lower than the weight of the prism assembly 11, which reduces the power consumption of the driving mechanism 12 and improves the driving accuracy of the driving mechanism 12. Moreover, the prism assembly 11 will not shake after power is cut off. At the same time, by driving the reflecting part 114 to achieve anti-shake of the camera module 1, there is no need for the entire prism assembly 11 to rotate, and there is no need to set up the space required for the overall movement of the prism assembly 11, thereby reducing the size of the camera module 1.

[0044] Optionally, the camera module 1 further includes an imaging chip, and the light emitted from the second transmission portion 113 can enter the imaging chip to achieve an imaging function.

[0045] like Figure 4 、 Figure 5 and Figure 6 As shown, according to some embodiments of the present application, optionally, the driving mechanism 12 includes: a memory alloy part 121, connecting the reflecting part 114 and the bracket 111, the memory alloy part 121 can be deformed, and is used to drive the reflecting part 114 to rotate around the first direction or the second direction; a reset part 122, connecting the reflecting part 114 and the bracket 111, and is used to drive the reflecting part 114 to reset.

[0046] In this embodiment, the driving mechanism 12 includes a memory alloy member 121 and a reset member 122. The memory alloy member 121 connects the reflective portion 114 and the bracket 111. The memory alloy member 121 can be controlled by voltage or current to change the length of the memory alloy member 121. Specifically, the memory alloy member 121 stretches or shrinks after being subjected to voltage or current. Since one end of the memory alloy member 121 is fixed to the bracket 111, and the reflective portion 114 is movably connected to the bracket 111, when the memory alloy member 121 stretches or shrinks, it can drive the reflective portion 114 to move, thereby changing the angle between the reflective portion 114 and the bracket 111, thereby changing the position of the reflective portion 114 and achieving compensation for the light offset angle. At the same time, the reset member 122 connects the reflective portion 114 and the bracket 111. When the voltage or current on the memory alloy member 121 disappears, the reset member 122 can drive the reflective portion 114 to reset, that is, drive the reflective portion 114 to return to its initial position. The memory alloy component 121 and the reset component 122 ensure the anti-shake function of the camera module 1.

[0047] like Figure 5 and Figure 6 As shown, according to some embodiments of the present application, optionally, the memory alloy member 121 includes an electrotropic memory alloy member 1211 , and the reset member 122 includes a spring 1221 .

[0048] In this embodiment, the shape memory alloy 121 includes an electrochromic memory alloy 1211, which generates a thermal effect when an electric current passes through it, thereby triggering a shape memory effect. The electrochromic memory alloy 1211 is small, lightweight, and has a fast response speed, enabling precise length changes. The reset element 122 includes a spring 1221, which has a simple structure, low manufacturing cost, long service life, and low noise, thereby improving the reliability of the drive mechanism 12.

[0049] like Figure 4 、 Figure 5 and Figure 6 As shown, according to some embodiments of the present application, optionally, the memory alloy member 121 is inserted into the spring 1221 .

[0050] In this embodiment, the memory alloy member 121 is disposed within the spring 1221, that is, the memory alloy member 121 is disposed within the interior space of the spring 1221. This can reduce the space occupied by the memory alloy member 121, thereby reducing the volume of the drive mechanism 12. Furthermore, even if the length of the memory alloy member 121 changes, the force applied to the spring 1221 in all directions is balanced, preventing the spring 1221 from tilting or twisting, thereby increasing the service life of the spring 1221.

[0051] like Figure 5 and Figure 6As shown, according to some embodiments of the present application, optionally, the driving mechanism 12 also includes: a first limit block 123, which is provided on the bracket 111, and one end of the memory alloy part 121 is connected to the first limit block 123; a second limit block 124, which is connected to the reflecting part 114, and the second limit block 124 is slidably connected to the bracket 111 along a third direction, and the other end of the memory alloy part 121 is connected to the second limit block 124.

[0052] In this embodiment, the driving mechanism 12 further includes a first limit block 123 and a second limit block 124, wherein the first limit block 123 is disposed on the bracket 111 and is fixedly connected to the bracket 111. The second limit block 124 is connected to the reflecting portion 114 and is slidably connected to the bracket 111 along the third direction. Figure 5 and Figure 6 The arrow in the figure indicates the direction of movement of the second limit block 124, that is, the second limit block 124 is slidably connected to the bracket 111 and can slide along the third direction. The two ends of the memory alloy member 121 are respectively connected to the first limit block 123 and the second limit block 124. In other words, the first limit block 123 is fixedly mounted on the bracket 111, and the second limit block 124 is slidably mounted on the bracket 111 and connected to the reflective portion 114. When the second limit block 124 slides along the third direction, it can drive the reflective portion 114 to rotate, thereby changing the offset angle of the light and realizing the anti-shake function of the camera module 1.

[0053] like Figure 4 、 Figure 5 and Figure 6 As shown, according to some embodiments of the present application, optionally, the second limiting block 124 includes a slot 1241 , and the reflecting portion 114 is locked in the slot 1241 .

[0054] In this embodiment, the second stopper 124 includes a slot 1241, and the reflective portion 114 is secured within the slot 1241. No fasteners, such as screws or nuts, are required to connect the second stopper 124 and the reflective portion 114, thereby improving assembly efficiency and reducing assembly costs. This also facilitates detachable connection between the second stopper 124 and the reflective portion 114. Furthermore, the engagement of the reflective portion 114 within the slot 1241 also reduces the volume occupied by the second stopper 124 and the reflective portion 114, thereby reducing the size of the camera module 1.

[0055] like Figure 4 、 Figure 5 and Figure 6 As shown, according to some embodiments of the present application, optionally, at least a portion of the second limiting block 124 is a flexible structure, and the flexible structure can be deformed to allow the reflecting portion 114 to rotate around the first direction or the second direction.

[0056] In this embodiment, when the second limit block 124 slides along the third direction, the reflecting portion 114 moves with the second limit block 124. In order to enable the reflecting portion 114 to rotate both around the first direction and around the second direction, it is necessary to set at least a portion of the second limit block 124 as a flexible structure, so that when the second limit block 124 moves along the same track, the reflecting portion 114 can achieve both rotation around the first direction and around the second direction.

[0057] Specifically, the slot 1241 of the second stopper 124 is a flexible structure. When the second stopper 124 slides, the reflective portion 114 can tilt and rotate in the first direction or the second direction. At the same time, the reflective portion 114 contacts the flexible structure, which reduces the possibility of the second stopper 124 damaging the reflective portion 114 when the reflective portion 114 tilts.

[0058] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, according to some embodiments of the present application, optionally, the bracket 111 is provided with a slide groove 1111 extending along the third direction, and the second limit block 124 is provided in the slide groove 1111 and can slide along the third direction; the bracket 111 is provided with a first limit portion 1112 on the side away from the first transmission portion 112 and the second transmission portion 113 along the third direction, and the first limit block 123 is provided with a second limit portion 1231, the first limit portion 1112 and the second limit portion 1231 are limited and cooperated, and the reflecting portion 114 is located on the side of the first limit block 123 close to the first transmission portion 112 and the second transmission portion 113.

[0059] In this embodiment, the bracket 111 is provided with a slide groove 1111 extending along the third direction. The second limiting block 124 is provided in the slide groove 1111 and can slide along the third direction, thereby realizing the sliding limit of the second limiting block 124. The bracket 111 is provided with a first limiting portion 1112 on the side away from the first transmission portion 112 and the second transmission portion 113 along the third direction. The first limiting block 123 is provided with a second limiting portion 1231. The first limiting portion 1112 can be one of the positioning hole and the positioning column, and the second limiting portion 1231 is the other of the positioning hole and the positioning column. The first limiting portion 1112 and the second limiting portion 1231 cooperate in the limiting position, so that the first limiting block 123 is fixed to the bracket 111, thereby reducing assembly errors. Figure 10The arrow in the figure indicates the assembly direction of the reflector 114. The positioning holes and the positioning posts cooperate to increase the contact area of the connection, thereby improving the connection strength and reliability. Furthermore, the reflector 114 is located on the side of the first stopper 123 near the first and second transmissive portions 112 and 113, allowing the reflector 114 to be located within the bracket 111, minimizing the space occupied by the reflector 114 outside the prism assembly 11 during movement.

[0060] like Figure 12 and Figure 13 As shown, according to some embodiments of the present application, optionally, the camera module 1 further includes a accommodating member 13, and a limiting plate 125 is provided on two opposite sides of the bracket 111 along the first direction, and the first transmitting portion 112 and the second transmitting portion 113 are arranged opposite to each other along the second direction, and the first transmitting portion 112, the second transmitting portion 113, the limiting plate 125 and the reflecting portion 114 enclose a cavity 126, and a fluid material 1261 is provided in the cavity 126; wherein, an opening 1251 is provided on the limiting plate 125, and the opening 1251 is connected to the cavity 126, and the accommodating member 13 is located outside the cavity 126 and is connected to the opening 1251, and a fluid material 1261 is provided in the cavity 126.

[0061] In this embodiment, along the first direction, limiting plates 125 are provided on opposite sides of the bracket 111, and the first transmitting portion 112 and the second transmitting portion 113 are arranged opposite to each other along the second direction. The first transmitting portion 112, the second transmitting portion 113, the limiting plates 125 and the reflecting portion 114 enclose a cavity 126, and a fluid material 1261 is provided in the cavity 126 to realize the conduction of light. An opening 1251 is provided on the limiting plate 125, and the opening 1251 is communicated with the cavity 126. The accommodating member 13 is located outside the cavity 126 and communicated with the opening 1251. When the reflecting portion 114 rotates about the first direction or the second direction, so that the volume in the cavity 126 decreases, the fluid material 1261 in the cavity 126 flows from the opening 1251 to the accommodating member 13. When the reflecting portion 114 rotates about the first direction or the second direction, so that the volume in the cavity 126 increases, the fluid material 1261 in the accommodating member 13 flows back into the cavity 126 from the opening 1251, so that the pressure in the cavity 126 is stable, thereby ensuring the reliability of light transmission.

[0062] It can be understood that the fluid material 1261 in the prism assembly 11 can maintain a certain pressure in the cavity 126. By controlling the pressure in the prism assembly 11, the pressure change can be avoided to affect the refractive index of light, and a constant pressure can be maintained in the prism assembly 11, thereby ensuring the stability and consistency of its optical performance.

[0063] According to some embodiments of the present application, optionally, the receiving member 13 includes an elastic receiving member.

[0064] In this embodiment, the container 13 comprises an elastic container. When the volume of cavity 126 decreases or the pressure increases, the fluid material 1261 is squeezed by cavity 126 and can enter the elastic container through opening 1251, thereby maintaining a constant pressure within cavity 126. When the volume of cavity 126 increases or the pressure decreases, the elastic container deforms, and the fluid material 1261 inside the elastic container enters cavity 126, thereby maintaining a constant pressure within cavity 126. The use of an elastic container can ensure a constant pressure within the prism assembly 11, improve the light reflection effect of the prism assembly 11, and thus enhance the stability and imaging quality of the camera module 1.

[0065] According to some embodiments of the present application, optionally, the reflective portion 114 has a polygonal structure, the reflective portion 114 includes at least three vertices, and the driving mechanism 12 is provided at the at least three vertices.

[0066] In this embodiment, the reflective portion 114 has a polygonal structure, includes at least three vertices, and the drive mechanism 12 is located at at least three vertices. In other words, the reflective portion 114 can be any polygon, includes at least three vertices, and the drive mechanism 12 is located at the three vertices. Compared to a case where the drive mechanism 12 is located on the edge of a polygon, the adjustment accuracy of the tilt angle of the reflective portion 114 is improved.

[0067] like Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 and Figure 19 As shown, according to some embodiments of the present application, optionally, the reflective portion 114 is a square structure, and the reflective portion 114 includes four vertices, and a driving mechanism 12 is provided at any vertex; wherein, as shown in FIG. Figure 14 As shown, along the circumference of the reflecting portion 114, among the three adjacent driving mechanisms 12, two adjacent driving mechanisms 12 drive the reflecting portion 114 to rotate so that the reflecting portion 114 rotates around a first direction, and the other two adjacent driving mechanisms 12 drive the reflecting portion 114 to rotate so that the reflecting portion 114 rotates around a second direction.

[0068] In this embodiment, the reflective portion 114 has a square structure and includes four vertices, with a drive mechanism 12 located at each vertex. That is, the drive mechanisms 12 are located at the four vertices of the square structure, and the four vertices of the reflective portion 114 can be adjusted individually. The symmetrical arrangement of the drive mechanisms 12 can more evenly distribute the load, preventing deformation or damage to the reflective portion 114 due to excessive local forces, thereby improving the adjustment stability of the reflective portion 114. Among these, along the circumference of the reflective portion 114, of the three adjacent drive mechanisms 12, two adjacent drive mechanisms 12 drive the reflective portion 114 to rotate so that the reflective portion 114 rotates in a first direction, and the other two adjacent drive mechanisms 12 drive the reflective portion 114 to rotate so that the reflective portion 114 rotates in a second direction. That is, of the three adjacent drive mechanisms 12, two adjacent drive mechanisms 12 can rotate the reflective portion 114 in the first direction, and the other two adjacent drive mechanisms 12 can rotate the reflective portion 114 in the second direction.

[0069] Optionally, when driving mechanisms 12 are provided at all four vertices, two adjacent driving mechanisms 12 serve as one group of adjusting mechanisms, and the other two driving mechanisms 12 serve as another group of adjusting mechanisms. In the process of adjusting the tilt angle of the reflecting portion 114, the two groups of adjusting mechanisms can cooperate with each other. When the memory alloy parts 121 in one group of adjusting mechanisms are extended, the memory alloy parts 121 in the other group of adjusting mechanisms are shortened, so that the reflecting portion 114 rotates about the first direction or the second direction, thereby reducing the local stress on the reflecting portion 114, increasing the service life of the reflecting portion 114, and at the same time improving the adjustment accuracy.

[0070] Optionally, when drive mechanisms 12 are provided at all four vertices, two adjacent drive mechanisms 12 serve as one group of adjustment mechanisms, and the other two drive mechanisms 12 serve as another group of adjustment mechanisms. In the process of adjusting the inclination angle of the reflective portion 114, one group of adjustment mechanisms drives the reflective portion 114 to change its inclination angle, and the other group of adjustment mechanisms stops operating. That is, the two adjacent drive mechanisms 12 drive the reflective portion 114 to rotate about the first direction or the second direction, and the other two drive mechanisms 12 stop operating, and no voltage or electricity is generated on the memory alloy member 121. The reflective portion 114 of the present application can also adjust the inclination angle of the reflective portion 114 only through the two adjacent drive mechanisms 12, thereby reducing the power consumption of the drive mechanisms 12.

[0071] like Figure 14 As shown, the incident light 3 enters the prism assembly 11, and under the action of the reflective portion 114, the outgoing light 4 is emitted from the prism assembly 11, and the outgoing light 4 at this time does not deviate. Figure 15As shown, the incident light 3 deviates toward the direction of point A and point B. At this time, the driving mechanism 12 at point C and point D moves along the direction of the arrow to realize the counterclockwise rotation of the reflective portion 114 around the first direction, thereby correcting the outgoing light 4. Figure 16 As shown, the incident light 3 deviates toward point C and point D. At this time, the driving mechanism 12 at point A and point B moves along the direction of the arrow to enable the reflecting part 114 to rotate clockwise around the first direction, thereby correcting the outgoing light 4.

[0072] like Figure 17 As shown, point A overlaps with point D, and point B overlaps with point C. The incident light 3 enters the prism assembly 11, and under the action of the reflective portion 114, the outgoing light 4 exits the prism assembly 11. At this time, the outgoing light 4 does not deviate. Figure 18 As shown, the incident light 3 deviates toward the direction of point A and point D. At this time, the driving mechanisms 12 at points A and D move in the direction of the arrows, and the driving mechanisms 12 at points B and C move in the direction of the arrows. That is, the driving mechanisms 12 at the four vertices simultaneously drive the reflective portion 114 to rotate counterclockwise around the second direction, thereby correcting the outgoing light 4. Figure 19 As shown, the incident light 3 is offset toward point B and point C. At this time, the driving mechanism 12 at point A and point D moves in the direction of the arrow, and the driving mechanism 12 at point B and point C moves in the direction of the arrow, that is, the driving mechanisms 12 at the four vertices simultaneously drive the reflecting part 114 to rotate clockwise around the second direction, thereby correcting the outgoing light 4.

[0073] like Figure 3 As shown, according to some embodiments of the present application, optionally, the second direction is perpendicular to the first direction.

[0074] In this embodiment, the second direction is perpendicular to the first direction, thereby achieving anti-shake performance of the camera module in two mutually perpendicular directions and increasing the anti-shake range.

[0075] Optionally, the reflective portion 114 includes a reflective surface for reflecting light, and specifically, in an initial state, the first direction and the second direction are both perpendicular to the normal of the reflective surface. Optionally, the third direction, the first direction, and the second direction are perpendicular to each other.

[0076] According to some embodiments of the present application, an electronic device is also proposed, including a shell with a light-through hole provided on the shell; the camera module 1 proposed in any of the above embodiments is arranged in the shell and arranged opposite to the light-through hole.

[0077] Specifically, the light entering the housing through the light hole can enter the camera module 1 through the first transmission portion 112 .

[0078] The electronic device according to the embodiment of the present application includes the camera module 1 as proposed in any of the above embodiments. Therefore, all the beneficial effects of the camera module 1 proposed in any of the above embodiments are achieved, which will not be repeated here.

[0079] In a specific application, the present invention realizes light direction correction by changing the bevel angle of the prism (prism assembly 11). Figure 14 、 Figure 15 and Figure 16 As shown in FIG, when the light is offset, the driving point set on the outside of the reflector (reflecting portion 114) drives the reflector to move up and down to achieve equivalent rotation. Taking 4-point drive as an example, the four driving points are marked as A, B, C, and D (for example, the four vertices of the reflector). Figure 15 As shown, when the light is offset, point C and point D move in the direction of the arrow, and point A and point B remain stationary or move in the opposite direction, so that the reflector rotates counterclockwise around the first rotation axis (first direction). Figure 16 As shown, when the light is offset, point A and point B move in the direction of the arrow, and point C and point D remain stationary or move in opposite directions, so that the reflector rotates equivalently clockwise around the first rotation axis (first direction).

[0080] like Figure 17 、 Figure 18 and Figure 19 As shown, point A overlaps with point D, and point B overlaps with point C. Figure 18 As shown, when the light is offset, point A and point D move in the direction of the arrow, and point B and point C move in the opposite direction, so that the reflector rotates counterclockwise around the second rotation axis (second direction). Figure 19 As shown, when the light is offset, point A and point D move in the direction of the arrow, and point B and point C move in the opposite direction, so that the reflector rotates equivalently clockwise around the second rotation axis (second direction).

[0081] This application drives the reflective bevel (reflecting portion 114) alone to correct the direction of light. Figure 3 As shown, the number of driving points is required to be at least 3, so as to realize the rotation of the reflecting surface around at least two axes, that is, around at least one of the first direction and the second direction.

[0082] This application provides a prism anti-shake design that achieves anti-shake by driving the inclined plane at four points. This design solution drives a single point by cooperating with an SMA (Shape Memory Alloys) memory alloy wire and a return spring (return element 122), and moves back and forth along the guide rail direction (third direction) to achieve anti-shake for periscope lens shooting. Figure 12As shown, the interior of the prism is a cavity 126 filled with a flowable material (fluid material 1261) to maintain pressure within the cavity when the reflective surface moves. The two transmissive surfaces can use a single lens or a dual lens, but this application uses a dual lens as an example. A fluid material replenishment cavity or storage cavity (accommodation member 13) is provided on the side of the prism. The surface of the storage cavity is made of a flexible material to store or provide the flowable material required for prism anti-shake.

[0083] The prism anti-shake structure (camera module 1) consists of 6 parts:

[0084] 1. Driving structure (driving mechanism 12): used to drive the prism reflective surface to rotate or translate to correct the angle of light;

[0085] 2. Slider (second limit block 124): The driving structure directly drives the component and is connected to the reflective surface;

[0086] 3. Transmission surface A (first transmission portion 112): The light incident surface is made of a hard sheet, and the shape of the sheet is not limited;

[0087] 4. Transmission surface B (second transmission portion 113): The light emitting surface is made of a hard sheet, and the shape of the sheet is not limited;

[0088] 5. Reflecting surface (reflecting portion 114): light reflecting surface;

[0089] 6. Prism bracket (bracket 111): used to fix various components.

[0090] The driving structure is a SMA (memory alloy) wire drive, which controls the contraction or relaxation of the SMA wire by changing the current and / or voltage. Figure 4 、 Figure 5 and Figure 6 As shown, the SMA wire connects the slider (second limit block 124) and the fixed block (first limit block 123). A reset spring (reset member 122) is set between the slider and the fixed block. When the SMA wire contracts, it pulls the slider along the guide rail toward the fixed block. When the SMA wire relaxes, the reset spring pushes the slider back along the guide rail. Figure 10 and Figure 11 As shown, the four corners of the reflecting surface are fixed using sliders, and then the sliders are assembled into the slider guide rails of the prism bracket.

[0091] like Figure 12 As shown, movement of the reflecting surface will cause pressure changes in the prism cavity, and a flow material replenishment cavity or a receiving cavity is set on one side of the prism groove.

[0092] like Figure 7 and Figure 8As shown, in order to cooperate with the movement of the slider (second limiting block 124), the prism bracket is provided with a fixing block (second limiting portion 1231), a positioning hole (first limiting portion 1112) and a slider guide rail (such as a slide groove 1111).
