Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of camera, in particular to a periscopic camera and electronic equipment. BACKGROUND

[0002] The periscopic camera is positioned for long-range shooting, and the influence of shaking on the shooting picture is greater than that of the traditional upright camera. Therefore, the optical anti-shake function has always been the key research direction of the periscopic camera. In the related technology, the periscopic camera with anti-shake design generally includes a shell, a reflection member (such as a prism), and an anti-shake assembly. The reflection member faces a light transmission part (also referred to as a light transmission window) on the shell, and the anti-shake assembly can drive the reflection member to move relative to the light transmission part to realize the anti-shake function. However, in the case of power failure of the anti-shake assembly, the reflection member is in a random deflection position within the mechanical rated anti-shake angle. The deflected reflection member is inclined relative to the light transmission part, that is, after the deflection of the reflection member, the edge of the reflection member is inclined relative to the edge of the light transmission part. At this time, the human eye can observe the inclination of the reflection member, and the inclined reflection member will appear unsightly. SUMMARY

[0003] The present application provides a periscopic camera and electronic equipment that can correct the inclination problem of the reflection member.

[0004] In a first aspect, the present application provides a periscopic camera, comprising:

[0005] a shell, the shell having a light transmission part that can transmit light;

[0006] a reflection assembly, the reflection assembly comprising a carrier frame, a reflection member, and a first righting member, the reflection member and the first righting member being carried on the carrier frame, the reflection member being arranged opposite to the light transmission part, and the reflection member being configured to reflect light from the light transmission part;

[0007] a righting assembly, the righting assembly comprising a second righting member, the second righting member being arranged opposite to the first righting member and being magnetically attracted to each other; and

[0008] a driving assembly, the driving assembly comprising a first anti-shake driving assembly, the first anti-shake driving assembly being configured to drive the reflection assembly to rotate relative to the light transmission part along a first direction when powered, a central axis of the first direction being a first central axis, an extension direction of the first central axis being an arrangement direction of the light transmission part and the reflection member;

[0009] The periscopic camera has a first normal state and a first anti-shake state, when the periscopic camera is in the first normal state, the first normal member is normal to the second normal member; when the periscopic camera is in the first anti-shake state, the first normal member is inclined to the second normal member, and the first normal member is subjected to magnetic attraction of the second normal member, and the first normal member can rotate in the first direction under the magnetic attraction of the second normal member to be normal to the second normal member.

[0010] In a second aspect, the present application further provides an electronic device, which comprises a device body and a periscopic camera.

[0011] The periscopic camera provided by the present application is provided with a first normal member and a second normal member, when the periscopic camera is in the first anti-shake state, the first normal member is inclined to the second normal member, and thus the second normal member provides a first normal torque to the first normal member. When the first anti-shake driving assembly is powered off, the first normal torque drives the reflecting assembly to rotate in the first direction until the first normal member and the second normal member are normal to each other. After the first normal member and the second normal member are normal to each other, the reflecting assembly is always maintained at the current position due to the mutual magnetic attraction between the two. Therefore, the periscopic camera provided by the present application can be maintained in the first normal state after the first anti-shake driving assembly is powered off, so that the reflecting member can be normal to the light transmission part in the first direction, thereby overcoming or weakening the problem of the inclination of the reflecting member in the related art.

It is explicitly contemplated that embodiments described herein can be combined to include claims directed to combinations of the embodiments.

[0030] Reference is made to Figure 1 and Figure 2 , the electronic device 100 includes a device body 20 and a periscopic camera 10, the periscopic camera 10 is mounted on the device body 20.

[0031] The electronic device 100 can be a mobile phone, a tablet computer, a notebook computer, a camera device, an ultra-mobile personal computer (UMPC), a wearable device (such as a smart watch, a bracelet, a VR device, etc.), a television, a vehicle-mounted device, an electronic reader, etc. The embodiments of the present application are only exemplarily described by taking the electronic device 100 as a mobile phone, but should not be regarded as a limitation to the present application.

[0032] The device body 20 refers to the main part of the electronic device 100, which includes electronic components that realize the main functions of the electronic device 100 and a shell 110 that protects and carries these electronic components. Taking a mobile phone as an example, the device body 20 can include a display screen 210, a middle frame 220, and a battery cover 230, the display screen 210 and the battery cover 230 are both connected to the middle frame 220 and are arranged on the opposite sides of the middle frame 220.

[0033] According to actual needs, the camera module can be exposed on any side of the electronic device 100, which is not limited in the present application. Taking a mobile phone as an example, the camera module can be arranged on the front, back, or side of the mobile phone. The front refers to the side of the mobile phone with the display screen 210; the back refers to the side of the mobile phone with the battery cover 230; and the side refers to the circumferential side of the middle frame 220 of the mobile phone. It can be understood that the definitions of the front, back, and side of the electronic device 100 can be different for different types of electronic devices 100, and the definitions of the front, back, and side of other types of electronic devices 100 are not described here.

[0034] Reference is made to Figure 3 and Figure 4 The present application provides a periscopic camera 10, which includes a shell 110, a reflection assembly 120, a back-to-normal assembly 130, a lens group 150, a photosensitive chip 160, and a driving assembly. The shell 110 is used to accommodate the reflection assembly 120, the back-to-normal assembly 130, and the driving assembly.

[0035] Please refer to Figure 3 and Figure 4 The housing 110 has a light-transmitting portion 111 that can transmit light. The light-transmitting portion 111 can also be referred to as a light-transmitting window, and external light can enter the housing 110 through the light-transmitting portion 111. The shape of the light-transmitting portion 111 can be, but is not limited to, a circle, an ellipse, a triangle, a rectangle, etc. The light-transmitting portion 111 can be a through hole on the housing 110, or a solid part on the housing 110 that can transmit light.

[0036] Please refer to Figures 5 to 7 The reflection assembly 120 includes a carrier frame 121, a reflection member 122, and a first return member 123. The reflection member 122 and the first return member 123 are both carried on the carrier frame 121. The reflection member 122 is arranged opposite to the light-transmitting portion 111, and is used to reflect light from the light-transmitting portion 111. The reflection member 122 can be, but is not limited to, a plane mirror, a triangular prism, etc., and the present application is exemplarily described by taking a triangular prism. It should be noted that the carrier frame 121, the reflection member 122, and the first return member 123 move synchronously.

[0037] Please refer to Figure 3 and Figure 4 The lens group 150 is arranged opposite to the reflection member 122, and the photosensitive chip 160 is arranged on the side of the lens group 150 away from the reflection member 122. The reflection member 122 reflects light from the light-transmitting portion 111 to the lens group 150, and the lens group 150 is used to focus the light on the photosensitive chip 160. The photosensitive chip 160 is used to receive light and convert the light signal into an electrical signal.

[0038] The lens group 150 includes a plurality of lenses, and the number of lenses can be, but is not limited to, 2, 3, 4, 5, 6, etc., and the material of the lenses can be, but is not limited to, transparent glass or transparent plastic. The photosensitive chip 160 can also be referred to as a photosensitive element, an image sensor, a Sensor, etc. The photosensitive chip 160 can be a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS).

[0039] The reflection member 122 includes an incident surface S1, a reflection surface S2, and an exit surface S3. The incident surface S1 is opposite to the light-transmitting portion 111, and the exit surface S3 is opposite to the lens group 150. The exit surface S3 is used to reflect light. Light passing through the light-transmitting portion 111 enters the reflection member 122 through the incident surface S1, is then reflected by the reflection surface S2, and finally exits from the exit surface S3.

[0040] Please refer to Figure 7 The back-to-normal assembly 130 includes a second back-to-normal piece 131, which is arranged opposite to the first back-to-normal piece 123 and is always magnetically attracted to each other.

[0041] Please refer to Figures 5 to 7 The driving assembly includes a first anti-shake driving assembly 141, which is used to drive the reflection assembly 120 to rotate relative to the light-transmitting part 111 in a first direction when powered. That is, the first anti-shake driving assembly 141 is used to drive the reflection assembly 120 to rotate to displace the shake, thereby realizing the anti-shake function in the first direction. The first direction is the rotation direction, which has positive and negative, that is, the reflection assembly 120 can rotate clockwise or counterclockwise in the first direction. The central axis of the first direction is the first central axis O1, and the extension direction of the first central axis O1 is the arrangement direction of the light-transmitting part 111 and the reflection part 122 (i.e. the relative direction of the light-transmitting part 111 and the reflection part 122).

[0042] The periscopic camera 10 has a first back-to-normal state and a first anti-shake state. When the periscopic camera 10 is in the first back-to-normal state, the first back-to-normal piece 123 is normal to the second back-to-normal piece 131. When the periscopic camera 10 is in the first anti-shake state, the first back-to-normal piece 123 is skewed to the second back-to-normal piece 131, and the second back-to-normal piece 131 provides a first back-to-normal torque to the first back-to-normal piece 123, so that the first back-to-normal piece 123 is normal to the second back-to-normal piece 131. That is, the first back-to-normal piece 123 is magnetically attracted by the second back-to-normal piece 131, and the first back-to-normal piece 123 can rotate in the first direction under the magnetic attraction of the second back-to-normal piece 131 to be normal to the second back-to-normal piece 131. Wherein, the first back-to-normal torque refers to the torque that can drive the reflection assembly 120 to rotate in the first direction.

[0043] In this embodiment, when the periscopic camera 10 is in the first back-to-normal state, the reflection part 122 and the light-transmitting part 111 are normal in the first direction, and the first back-to-normal piece 123 and the second back-to-normal piece 131 are also normal at this time. When the periscopic camera 10 is in the first anti-shake state, the reflection part 122 is skewed to the light-transmitting part 111 in the first direction, and the first back-to-normal piece 123 is also skewed to the second back-to-normal piece 131 at this time. By driving the reflection assembly 120 to rotate through the first anti-shake driving assembly 141, the camera module can be switched between the first back-to-normal state and the first anti-shake state.

[0044] Assuming that the current periscope camera 10 is in the first anti-shake state, since the first righting member 123 is skewed relative to the second righting member 131, the magnetic attraction of the second righting member 131 to the first righting member 123 will form a first righting moment; if the first anti-shake driving assembly 141 is in the energized state at this time, the reflecting assembly 120 can be maintained at the current position under the action of the first anti-shake driving assembly 141, i.e., the first righting member 123 can be maintained in the skewed position relative to the second righting member 131; if the first anti-shake driving assembly 141 is in the de-energized state at this time, the first righting moment will drive the entire reflecting assembly 120 to rotate through the first righting member 123 until the first righting member 123 is right for the second righting member 131, i.e., the periscope camera 10 changes from the first anti-shake state to the first righting state, at which time the first righting moment disappears and the reflecting assembly 120 no longer rotates. When the periscope camera 10 is in the first righting state, the first righting member 123 and the second righting member 131 are still magnetically attracted to each other, and if the first anti-shake driving assembly 141 is in the de-energized state at this time, the mutual magnetic attraction between the first righting member 123 and the second righting member 131 allows the reflecting assembly 120 to be maintained at the current position, i.e., the periscope camera 10 can be maintained in the first righting state.

[0045] With the user's anti-shake shooting scene as an example: when the user is using the electronic device 100 to shoot in a direction with shaking, at this time, the first anti-shake driving assembly 141 drives the reflecting assembly 120 to rotate in the positive direction of the first direction to compensate for the shaking. During the rotation of the reflecting assembly 120, the first return piece 123 gradually tilts relative to the second return piece 131, and the first return torque acting on the first return piece 123 gradually increases, which has a tendency to drive the reflecting assembly 120 to rotate in the negative direction of the first direction. When the user ends the shooting and closes the camera, the first return torque drives the reflecting assembly 120 to move in the negative direction of the first direction until the first return piece 123 and the second return piece 131 are directly opposite. After the first return piece 123 and the second return piece 131 are directly opposite, the reflecting assembly 120 is always maintained in the current position due to the mutual magnetic attraction between the two, that is, the periscopic camera 10 can be maintained in the first return state. Similarly, when the user is using the electronic device 100 to shoot in another direction with shaking, at this time, the first anti-shake driving assembly 141 drives the reflecting assembly 120 to rotate in the negative direction of the first direction to compensate for the shaking. During the rotation of the reflecting assembly 120, the first return piece 123 gradually tilts relative to the second return piece 131, and the first return torque acting on the first return piece 123 gradually increases, which has a tendency to drive the reflecting assembly 120 to rotate in the positive direction of the first direction. When the user ends the shooting and closes the camera, the first return torque drives the reflecting assembly 120 to move in the positive direction of the first direction until the first return piece 123 and the second return piece 131 are directly opposite. After the first return piece 123 and the second return piece 131 are directly opposite, the reflecting assembly 120 is always maintained in the current position due to the mutual magnetic attraction between the two, that is, the periscopic camera 10 can be maintained in the first return state.

[0046] In summary, the periscopic camera 10 provided in the present application is provided with the first return piece 123 and the second return piece 131. When the periscopic camera 10 is in the first anti-shake state, the first return piece 123 is tilted relative to the second return piece 131, and the second return piece 131 will provide the first return torque to the first return piece 123. When the first anti-shake driving assembly 141 is powered off, the first return torque will drive the reflecting assembly 120 to rotate in the first direction until the first return piece 123 and the second return piece 131 are directly opposite. After the first return piece 123 and the second return piece 131 are directly opposite, the reflecting assembly 120 is always maintained in the current position due to the mutual magnetic attraction between the two. Therefore, the periscopic camera 10 provided in the present application can maintain the first return state after the first anti-shake driving assembly 141 is powered off, so that the reflecting piece 122 can be directly opposite the light-transmitting portion 111 in the first direction, thereby overcoming or weakening the problem of tilting of the reflecting piece 122 in the related art.

[0047] Please refer to Figure 7 and Figure 8 Optionally, the carrier frame 121 has a first surface M1 and a second surface M2, the first surface M1 faces the light-transmitting portion 111, that is, the first surface M1 is the top surface of the carrier frame 121. The second surface M2 is away from the first surface M1, that is, the second surface M2 is the bottom surface of the carrier frame 121. The returning component 130 faces the second surface M2. In other words, the returning component 130 is arranged on the side of the carrier frame 121 away from the light-transmitting portion 111. Further, the first returning component 123 is mounted on the side of the carrier frame 121 having the second surface M2.

[0048] Further, at least one of the first returning component 123 and the second returning component 131 is a magnet capable of generating a magnetic field, and the first returning component 123 and the second returning component 131 are magnetically attracted to each other. In an embodiment, the first returning component 123 is a magnet capable of generating a magnetic field, and the second returning component 131 is a non-magnet (such as iron, steel, etc.). In another embodiment, the second returning component 131 is a magnet capable of generating a magnetic field, and the first returning component 123 is a non-magnet (such as iron, steel, etc.). In yet another embodiment, the first returning component 123 and the second returning component 131 are both magnets. It should be noted that the magnet referred to in the present application means a magnetic object capable of maintaining its magnetism for a long time. The present application only exemplarily illustrates the second returning component 131 as a magnet and the first returning component 123 as a non-magnet.

[0049] Please refer to Figure 9 The second returning component 131 includes a first returning magnet 1311 and a second returning magnet 1312. The first returning component 123 includes a first portion 1231, an intermediate portion 1235, and a second portion 1232. The first portion 1231 and the second portion 1232 are respectively connected to the opposite sides of the intermediate portion 1235, that is, the first portion 1231, the intermediate portion 1235, and the second portion 1232 are connected in sequence, and the connection shape of the three is approximately a long strip. In the opposite direction of the reflecting component 120 and the lens group 150 (hereinafter referred to as the preset direction X), the size of the first portion 1231 is smaller than the size of the first returning magnet 1311, and the size of the second portion 1232 is smaller than the size of the second returning magnet 1312. Optionally, the first central axis O1 passes through the intermediate portion 1235.

[0050] When the periscope camera 10 is in the first alignment state, the first portion 1231 is aligned with the first alignment magnet 1311, and the second portion 1232 is aligned with the second alignment magnet 1312. That is, the first portion 1231 is aligned with the middle of the first alignment magnet 1311 in the preset direction X, and the second portion 1232 is aligned with the middle of the second alignment magnet 1312 in the preset direction X.

[0051] When the periscope camera 10 is in the first anti-shake state, the first portion 1231 is skewed to the first alignment magnet 1311, and the second portion 1232 is skewed to the second alignment magnet 1312.

[0052] Please refer to Figure 9 and Figure 10 , the first portion 1231 will be subjected to two magnetic forces from the first alignment magnet 1311 in the preset direction X: a first force F1 and a second force F2, both of which are parallel to the preset direction X and in opposite directions.

[0053] Please refer to Figure 9 , when the periscope camera 10 is in the first alignment state, since the first portion 1231 is aligned with the first alignment magnet 1311, the first force F1 and the second force F2 are of the same magnitude, and the resultant force of the first force F1 and the second force F2 (hereinafter referred to as the first resultant force) is zero, and the first moment formed by the first resultant force is also zero.

[0054] Please refer to Figure 10 , when the periscope camera 10 is in the first anti-shake state, since the first portion 1231 is skewed to the first alignment magnet 1311, the first force F1 and the second force F2 are of different magnitudes, the first resultant force is not zero, and the first moment is also not zero.

[0055] Please refer to Figure 9 and Figure 10 , the second portion 1232 will be subjected to two magnetic forces from the second alignment magnet 1312 in the preset direction X: a third force F3 and a fourth force F4, both of which are parallel to the preset direction X and in opposite directions.

[0056] Please refer to Figure 9When the periscopic camera 10 is in the first back-normal state, since the second part 1232 is normal to the second back-normal magnet 1312, the third force F3 and the fourth force F4 are of the same size, the resultant force of the third force F3 and the fourth force F4 (hereinafter referred to as the second resultant force) is zero, and the second moment formed by the second resultant force is also zero.

[0057] Please refer to Figure 10 When the periscopic camera 10 is in the first anti-shake state, since the second part 1232 is skewed to the second back-normal magnet 1312, the third force F3 and the fourth force F4 are of different sizes, the second resultant force is not zero, and the second moment is also not zero.

[0058] Further, the first moment and the second moment are in the same direction, and the sum of the two is equal to the first back-normal moment. When the periscopic camera 10 is in the first back-normal state, the first moment and the second moment are both zero, so the first back-normal moment is also zero. When the periscopic camera 10 is in the first anti-shake state, the first moment and the second moment are not zero, so the first back-normal moment is also not zero. If the driving assembly is powered off, the non-zero first back-normal moment can drive the reflecting assembly 120 to rotate, so that the first back-normal part 123 and the second back-normal part 131 return the periscopic camera 10 to the first back-normal state.

[0059] Please refer to Figure 9 Please refer to Figure 10 The first back-normal part 123 further comprises a third part 1233 and a fourth part 1234, the third part 1233 and the fourth part 1234 are respectively connected to the opposite sides of the middle part 1235, and the first part 1231, the third part 1233, the second part 1232, and the fourth part 1234 are arranged in the first direction in sequence, and the first back-normal part 123 as a whole is in the shape of a "cross". The first back-normal part 123 can be a symmetrical structure, which is conducive to design and magnetic attraction balance.

[0060] The third part 1233 is located between the first back-normal magnet 1311 and the second back-normal magnet 1312, and the directions of the magnetic attraction of the first back-normal magnet 1311 and the second back-normal magnet 1312 to the third part 1233 are opposite, that is, the first back-normal magnet 1311 and the second back-normal magnet 1312 both magnetically attract the third part 1233, and the directions of the magnetic attraction of the first back-normal magnet 1311 to the third part 1233 and the magnetic attraction of the second back-normal magnet 1312 to the third part 1233 are opposite to each other.

[0061] The fourth part 1234 is located between the first return positive magnet 1311 and the second return positive magnet 1312, and the first return positive magnet 1311 and the second return positive magnet 1312 are respectively opposite to the magnetic attraction direction of the fourth part 1234, that is, the first return positive magnet 1311 and the second return positive magnet 1312 both magnetically attract the fourth part 1234, and the direction of the magnetic attraction force of the fourth part 1234 by the first return positive magnet 1311 and the direction of the magnetic attraction force of the fourth part 1234 by the second return positive magnet 1312 are opposite to each other.

[0062] The resultant force of the third part 1233 can form a third moment, and the resultant force of the fourth part 1234 can form a fourth moment. The directions of the first moment, the second moment, the third moment, and the fourth moment are the same, and the sum of the four moments is equal to the first return positive moment. It can be understood that after the third part 1233 and the fourth part 1234 are arranged on the basis of the first part 1231 and the second part 1232, the first return positive moment can be larger, and when the first return positive part 123 is skewed relative to the second return positive part 131, the larger first return positive moment is more conducive to driving the first return positive part 123 to automatically align with the second return positive part 131. This also shows that after the first return positive part 123 and the second return positive part 131 are aligned, the first return positive part 123 is less likely to be skewed.

[0063] Please refer to Figure 9 and Figure 10 , the first return positive magnet 1311 and the second return positive magnet 1312 are arranged at intervals. The first center axis O1 is located between the first return positive magnet 1311 and the second return positive magnet 1312. It can be understood that arranging the first return positive magnet 1311 and the second return positive magnet 1312 at intervals can increase the distance between the first return positive magnet 1311 and the first center axis O1, thereby increasing the above-mentioned first moment. Similarly, the distance between the second return positive magnet 1312 and the first center axis O1 can also be increased, thereby increasing the above-mentioned second moment, and ultimately increasing the first return positive moment. Of course, arranging the first return positive magnet 1311 and the second return positive magnet 1312 at intervals can also save materials and reduce costs.

[0064] Optionally, in the direction of the reflective member 122 towards the light-transmitting portion 111, the polar arrangement direction of the first return N magnet 1311 is the same as the polar arrangement direction of the second return N magnet 1312. In an embodiment, the N pole of the first return N magnet 1311 and the N pole of the second return N magnet 1312 are both towards the light-transmitting portion 111, and the S pole of the first return N magnet 1311 and the S pole of the second return N magnet 1312 are both away from the light-transmitting portion 111. In another embodiment, the S pole of the first return N magnet 1311 and the S pole of the second return N magnet 1312 are both towards the light-transmitting portion 111, and the N pole of the first return N magnet 1311 and the N pole of the second return N magnet 1312 are both away from the light-transmitting portion 111.

[0065] By setting the polar arrangement direction of the first return N magnet 1311 to be the same as the polar arrangement direction of the second return N magnet 1312, the mutual magnetic attraction between the first return N magnet 1311 and the second return N magnet 1312 is reduced, so that the magnetic attraction between the first return N magnet 1311 and the first return N member 123, and the magnetic attraction between the second return N magnet 1312 and the first return N member 123 are both larger, which is conducive to the process of the periscopic camera 10 autonomously changing from the first anti-shake state to the first return N state, and is also conducive to the periscopic camera 10 always maintaining the first return N state.

[0066] In the reverse angle, if the first return magnet 1311 and the second return magnet 1312 are arranged in opposite directions, for example, the N pole of the first return magnet 1311 and the S pole of the second return magnet 1312 are both directed to the light-transmitting part 111, which makes the N pole of the first return magnet 1311 and the S pole of the second return magnet 1312 closer, and the N pole of the first return magnet 1311 and the S pole of the second return magnet 1312 form at least partially closed magnetic lines, that is, at least partially magnetic lines start from the N pole of the first return magnet 1311 and finally reach the S pole of the second return magnet 1312. Specifically, the magnetic lines starting from the N pole of the first return magnet 1311, part of which reaches the S pole of the first return magnet 1311, part of which reaches the S pole of the second return magnet 1312, and the remaining part reaches the first return part 123. Similarly, the magnetic lines starting from the N pole of the second return magnet 1312, part of which reaches the S pole of the second return magnet 1312, part of which reaches the S pole of the first return magnet 1311, and the remaining part reaches the first return part 123. In other words, after being arranged as “the N pole of the first return magnet 1311 and the S pole of the second return magnet 1312 are both directed to the light-transmitting part 111”, the mutual magnetic attraction between the first return magnet 1311 and the second return magnet 1312 is strengthened, while the magnetic attraction between the first return magnet 1311 and the first return part 123 is weakened, and the magnetic attraction between the second return magnet 1312 and the first return part 123 is also weakened, and the above-mentioned first return torque is reduced, which is not conducive to the periscopic camera 10 from the first anti-shake state to the first return state, and is not conducive to the periscopic camera 10 to maintain the first return state all the time.

[0067] Please refer to Figure 11 In the opposite direction of the reflecting member 122 and the light-transmitting part 111, the first return part 123 and the second return part 131 are always spaced apart from each other. That is, no matter whether the periscopic camera 10 is in the first return state or the first anti-shake state, the first return part 123 and the second return part 131 are always spaced apart, and it can be understood that the first return part 123 and the second return part 131 are spaced apart, thereby avoiding the friction between the first return part 123 and the second return part 131 during the rotation of the reflecting assembly 120 relative to the return assembly 130.

[0068] Please refer to Figure 12 and Figure 13The first anti-shake driving assembly 141 includes a first magnet 1411 and a first coil 1412. The first magnet 1411 is connected to the reflecting assembly 120. The first coil 1412 is arranged opposite to and spaced apart from the first magnet 1411. The first coil 1412 is configured to generate a magnetic action on the first magnet 1411 when energized, so as to drive the carrier frame 121 to rotate around the first central axis O1 through the first magnet 1411.

[0069] In the embodiment, the number of the first anti-shake driving assembly 141 can be one, two, three, etc. The present application takes two as an example (i.e., two first coils 1412 and two first magnets 1411). The carrier frame 121 further has a third surface M3 and a fourth surface M4 arranged opposite to each other, which are side surfaces of the carrier frame 121. One of the two first magnets 1411 is fixed on the side of the carrier frame 121 having the third surface M3, and the other first magnet 1411 is fixed on the side of the carrier frame 121 having the fourth surface M4. Each first magnet 1411 is arranged opposite to one first coil 1412. The first coil 1412 and the first magnet 1411 are spaced apart from each other. The two first anti-shake driving assemblies 141 jointly drive the reflecting assembly 120 to rotate around the first central axis O1. Since the first magnet 1411 is fixed on the reflecting assembly 120, when the reflecting assembly 120 rotates, the first magnet 1411 will also rotate with the reflecting assembly 120. The first coil 1412 can be directly or indirectly fixed on the housing 110. When the reflecting assembly 120 rotates, the first coil 1412 will not rotate.

[0070] Please refer to Figure 12The first anti-vibration driving assembly 141 further comprises a first isolation piece 1413 which is at least partially arranged on one side of the first magnet 1411 close to the first return piece 123 or the second return piece 131. The first isolation piece 1413 is an object which can be attracted by a magnet, and the material of the first isolation piece 1413 can be, but is not limited to, steel, iron, etc. Since the first return piece 123 and the second return piece 131 are arranged adjacently, the first isolation piece 1413 is arranged between the first magnet 1411 and the first return piece 123, which means that the first isolation piece 1413 is also arranged between the first magnet 1411 and the second return piece 131. The first isolation piece 1413 can isolate the magnetic field, so that the magnetic field of the first magnet 1411 and the magnetic field of the first return piece 123 do not affect each other, and the magnetic field of the first magnet 1411 and the magnetic field of the second return piece 131 do not affect each other, thereby ensuring that the alignment effect of the return piece 122 and the light transmission portion 111 is good. One of the two first isolation pieces 1413 can be fixed on one side of the carrier frame 121 having the third surface M3, and the other first isolation piece 1413 is fixed on one side of the carrier frame 121 having the fourth surface M4. The first magnet 1411 can be fixed on the first isolation piece 1413.

[0071] Please refer to Figure 14 , Figure 14 is a graph of the relationship between the rotation angle of the return piece 122 along the first direction and the first return torque. In Figure 14 , the abscissa represents the rotation angle of the return piece 122 along the first direction, and the ordinate represents the size of the first return torque, in units of mN·mm. It can be seen that the first return torque is linearly distributed with the rotation angle of the return piece 122, and the greater the rotation angle of the return piece 122, the greater the first return torque; the smaller the rotation angle of the return piece 122, the smaller the first return torque; when the rotation angle of the return piece 122 is 0°, the first return torque is close to 0 mN·mm. Since there are manufacturing, assembly and other errors in the product, the line shown in the graph does not pass through the coordinate origin. It should be noted that Figure 14 , the positive and negative coordinates only represent different directions, not the size of the value.

[0072] Please refer to Figure 12 and Figure 15The driving assembly further comprises a second anti-shake driving assembly 142, which comprises a second magnet 1421 and a second coil 1422. The second magnet 1421 is connected to the returning assembly 130. The second coil 1422 is arranged opposite to and spaced apart from the second magnet 1421. The second coil 1422 is configured to generate a magnetic action on the second magnet 1421 when energized, so as to drive the returning assembly 130 and the reflecting assembly 120 to rotate in a second direction through the second magnet 1421. That is, the second anti-shake driving assembly 142 is configured to drive the reflecting assembly 120 to rotate, so as to displace the shake and realize the anti-shake function in the second direction. The second direction is a rotating direction, which has positive and negative directions, that is, the reflecting assembly 120 can rotate clockwise or counterclockwise in the second direction. The central axis of the second direction is a second central axis O2, which is not parallel to the first central axis O1. The first central axis O1 and the second central axis O2 can be perpendicular to each other. In the present application, the extension direction of the second central axis O2 is the relative direction of the third surface M3 and the fourth surface M4.

[0073] It should be noted that the second anti-shake driving assembly 142 drives the reflecting assembly 120 to move by driving the returning assembly 130, that is, when the second anti-shake driving assembly 142 is energized and driven, the returning assembly 130 and the reflecting assembly 120 rotate in the second direction. Since the second magnet 1421 is fixed on the returning assembly 130, when the returning assembly 130 rotates, the second magnet 1421 will move with the returning assembly 130. The second coil 1422 can be directly or indirectly fixed on the housing 110, and when the returning assembly 130 rotates, the second coil 1422 will not rotate.

[0074] Please refer to Figure 12 and Figure 15 The returning assembly 130 further comprises a second isolation piece 132, which is arranged between the second returning piece 131 and the second magnet 1421. The second isolation piece 132 is an object that can be attracted by a magnet, and its material can be but is not limited to steel, iron and the like. By arranging the second isolation piece 132 between the second returning piece 131 and the second magnet 1421, the magnetic field of the second magnet 1421 and the magnetic field of the second returning piece 131 can not affect each other, thereby ensuring that the reflecting assembly 122 and the light-transmitting portion 111 are well aligned.

[0075] Please refer to Figure 12 and Figure 15The periscopic camera 10 further comprises a third homing member 170 disposed on a side of the second coil 1422 facing away from the second magnet 1421. The third homing member 170 can be directly or indirectly fixed on the housing 110. The second coil 1422 can be directly or indirectly fixed on the third homing member 170, and the second coil 1422 is located on a side of the third homing member 170 facing the second magnet 1421. The third homing member 170 is disposed opposite to the second magnet 1421 and magnetically attracted to each other. The material of the third homing member 170 can be, but is not limited to, steel, iron, etc. Of course, the third homing member 170 can also be a magnet that can generate a magnetic field.

[0076] The periscopic camera 10 has a second homing state and a second anti-shake state. When the periscopic camera 10 is in the second homing state, the second magnet 1421 is right to the third homing member 170. When the periscopic camera 10 is in the second anti-shake state, the second magnet 1421 is skewed to the third homing member 170, and the third homing member 170 provides a second homing torque to the second magnet 1421 to make the second magnet 1421 right to the third homing member 170. That is, the second magnet 1421 magnetically attracts the third homing member 170, and the second magnet 1421 can rotate along the second direction by magnetically attracting the third homing member 170 to be right to the third homing member 170.

[0077] In the embodiment, when the periscopic camera 10 is in the second homing state, the reflecting member 122 and the light-transmitting part 111 are right to each other in the second direction, and the second magnet 1421 and the third homing member 170 are also right to each other at this time. When the periscopic camera 10 is in the second anti-shake state, the reflecting member 122 is skewed to the light-transmitting part 111 in the second direction, and the second magnet 1421 is also skewed to the third homing member 170 at this time. By driving the reflecting assembly 120 to rotate through the second anti-shake driving assembly 142, the camera module can be switched between the second homing state and the second anti-shake state.

[0078] Assuming that the current periscope camera 10 is in the second anti-shake state, since the second magnet 1421 is skewed relative to the third restoring member 170, the magnetic attraction force of the third restoring member 170 on the second magnet 1421 will form a second restoring torque; if the second anti-shake driving assembly 142 is in an energized state at this time, the reflecting assembly 120 can be maintained at the current position under the action of the second anti-shake driving assembly 142, that is, the second magnet 1421 can be maintained in the skewed position relative to the third restoring member 170; if the second anti-shake driving assembly 142 is in a de-energized state at this time, the second restoring torque will drive the entire reflecting assembly 120 to rotate through the second magnet 1421 until the second magnet 1421 is directly opposite the third restoring member 170, that is, the periscope camera 10 changes from the second anti-shake state to the second restoring state, at this time, the second restoring torque disappears, and the reflecting assembly 120 no longer rotates. When the periscope camera 10 is in the second restoring state, the second magnet 1421 and the third restoring member 170 are still magnetically attracted to each other, and if the second anti-shake driving assembly 142 is in a de-energized state at this time, the mutual magnetic attraction between the second magnet 1421 and the third restoring member 170 enables the reflecting assembly 120 to be maintained at the current position, that is, the periscope camera 10 can be maintained in the second restoring state.

[0079] With the user's anti-shake shooting scene as an example: when the user is using the electronic device 100 to shoot in a direction with shaking, at this time, the second anti-shake driving assembly 142 drives the reflecting assembly 120 to rotate in the positive direction of the second direction to compensate for the shaking. During the rotation of the reflecting assembly 120, the second magnet 1421 gradually inclines relative to the third restoring member 170, and the second restoring torque acting on the second magnet 1421 gradually increases, which has a tendency to drive the reflecting assembly 120 to rotate in the negative direction of the second direction. When the user ends the shooting and closes the camera, the second restoring torque drives the reflecting assembly 120 to move in the negative direction of the second direction until the second magnet 1421 and the third restoring member 170 are directly opposite. After the second magnet 1421 and the third restoring member 170 are directly opposite, the reflecting assembly 120 is always maintained in the current position due to the mutual magnetic attraction between the two, that is, the periscopic camera 10 can be maintained in the second restoring state. Similarly, when the user is using the electronic device 100 to shoot in another direction with shaking, at this time, the second anti-shake driving assembly 142 drives the reflecting assembly 120 to rotate in the negative direction of the second direction to compensate for the shaking. During the rotation of the reflecting assembly 120, the second magnet 1421 gradually inclines relative to the third restoring member 170, and the second restoring torque acting on the second magnet 1421 gradually increases, which has a tendency to drive the reflecting assembly 120 to rotate in the positive direction of the second direction. When the user ends the shooting and closes the camera, the second restoring torque drives the reflecting assembly 120 to move in the positive direction of the second direction until the second magnet 1421 and the third restoring member 170 are directly opposite. After the second magnet 1421 and the third restoring member 170 are directly opposite, the reflecting assembly 120 is always maintained in the current position due to the mutual magnetic attraction between the two, that is, the periscopic camera 10 can be maintained in the second restoring state.

[0080] When the periscopic camera 10 is in the first restoring state and the second restoring state at the same time, the reflecting member 122 is directly opposite the light-transmitting portion 111 in the first direction and the second direction. When the periscopic camera 10 is in the first anti-shake state and the second anti-shake state at the same time, the reflecting member 122 is inclined to the light-transmitting portion 111 in the first direction and the second direction. In the present application, through the above-mentioned structure, when the first anti-shake driving assembly 141 and the second anti-shake driving assembly 142 are both powered off, under the action of the first restoring torque and the second restoring torque, the periscopic camera 10 will finally be in the first restoring state and the second restoring state at the same time, and be maintained in the first restoring state and the second restoring state.

[0081] Although the embodiments of the present application have been shown and described above, it is to be understood that the above-described embodiments are merely exemplary, and are not to be construed as limiting the present application, and that modifications, substitutions, replacements and variations of the above-described embodiments can be made by those skilled in the art within the scope of the present application, and such improvements and refinements are also considered as the protection scope of the present application.
