In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0061] In addition, it should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0062] Unless specifically stated or defined otherwise, the term "and / or" used in the present invention includes any and all combinations of one or more of the associated listed items.

[0063] like Figures 1 to 4 For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent with the left and right directions mentioned below. Figure 1 The left and right directions are consistent with the Figure 1 The projection direction itself is consistent.

[0064] A camera mechanism includes a base 10, a support base 11, a first adjustment base 12 rotatably mounted on the support base 11, a second adjustment base 13 rotatably mounted on the first adjustment base 12, and a first camera 15 mounted on the second adjustment base 13; the rotation axis of the first adjustment base 12 and the rotation axis of the second adjustment base 13 are perpendicular to each other. First pivots 19 are provided on both left and right sides of the first adjustment base 12, the first adjustment base 12 is rotatably mounted on the support base 11 via the first pivots 19, and the rotation axis of the first adjustment base 12 is horizontally arranged from left to right. Second pivots 20 are provided on both upper and lower ends of the second adjustment base 13, the second adjustment base 13 is rotatably mounted on the first adjustment base 12 via the second pivots 20, and the rotation axis of the second adjustment base 13 is vertically arranged from top to bottom. When the first adjustment seat 12 rotates, it drives the second adjustment seat 13 to flip up and down, and when the second adjustment seat 13 rotates, it drives the first camera 15 to flip left and right, thereby adjusting the shooting angle of the first camera 15 and increasing the shooting area or range of the first camera 15. At the same time, the first adjustment seat 12 and the second adjustment seat 13 are driven to rotate to achieve anti-shake when taking photos or videos.

[0065] In one embodiment, the camera mechanism further includes a second camera 14 mounted on the first adjustment seat 12 .

[0066] Optionally, one of the second camera 14 and the first camera 15 is a main camera, and the other is a secondary camera. The second camera 14 is mounted on the first adjustment seat 12 and can be turned upside down. The support seat 11, the first adjustment seat 12, and the second adjustment seat 13 can be driven manually or by a driving component such as a motor.

[0067] In one embodiment, the base 10 has a storage slot 101, and the support base 11 is movably mounted on the base 10 to move between a storage position stored in the storage slot 101 and an extended position extending out of the storage slot 101. By providing a second camera 14 and a first camera 15 that can be stored, the second camera 14 and the first camera 15 can be protected, and the screen ratio can be increased to improve the user experience. When the support base 11 is in the storage position, the first adjustment base 12 moves downward and is located in the storage slot 101. The first adjustment base 12, the second adjustment base 13, the second camera 14, and the first camera 15 are all located in the storage slot 101 to protect the second camera 14 and the first camera 15. When the support base 11 is in the extended position, the first adjustment base 12 extends out of the storage slot 101. When the first adjustment base 12 extends out of the storage slot 101, it drives the first adjustment base 12, the second adjustment base 13, the second camera 14, and the first camera 15 to extend above the base 10, so as to facilitate shooting. During shooting, the second camera 14 and the first camera 15 are driven to rotate by rotating the first adjustment base 12 and the second adjustment base 13 to adjust the shooting direction. The rotation of the first adjustment base 12 and the second adjustment base 13 increases the shooting range and area.

[0068] In addition, the rotation of the first adjustment seat 12 and the second adjustment seat 13 can be performed before the support seat 11 is extended, can be performed simultaneously when the support seat 11 is extended, or can be performed after the support seat 11 is extended.

[0069] Specifically, the storage slot 101 is opened above the base 10, and the lower end of the support seat 11 is slidably mounted on the base 10, and the support seat 11 is driven when it slides up and down. When the support seat 11 moves upward, the first adjustment seat 12, the second adjustment seat 13, the second camera 14, and the first camera 15 move upward together and extend out, and when the first adjustment seat 12 moves downward, the first adjustment seat 12, the second adjustment seat 13, the second camera 14, and the first camera 15 move downward together and enter the storage slot 101.

[0070] In addition, it is understandable that the support base 11 can also be installed on the base 10 in a flip-over manner.

[0071] In this way, when the support seat 11 moves to the extended position, the camera mechanism increases the range and area of ​​shooting by driving the first adjustment seat 12 and the second adjustment seat 13 to rotate. The first adjustment seat 12 can change the front target of the second camera 14 and the first camera 15 by flipping back and forth, such as books, exercise books, etc. The first camera 15 swings left and right following the second adjustment seat 13, and the first camera 15 rotates within the range of ±30° following the second adjustment seat 13, increasing the recognizable area of ​​the first camera 15. The second camera 14 can be used as the main camera or cooperate with the first camera 15 for intelligent recognition. Through the rotation of the first adjustment seat 12, the second camera 14 and the first camera 15 are driven to rotate within a range of 69°.

[0072] In one embodiment, the camera structure further includes a third driver 16, a first driver 17, and a second driver 18. The third driver 16, the first driver 17, and the second driver 18 can be the same driving device or different driving devices. For example, the third driver 16, the first driver 17, and the second driver 18 are all piezoelectric motors, which drive the support seat 11, the first adjustment seat 12, and the second adjustment seat 13 to move through the transmission assembly, and can accurately control the movement of the support seat 11, the first adjustment seat 12, and the second adjustment seat 13. Compared with traditional motors, piezoelectric motors are smaller in size, which can reduce the overall volume of the camera structure.

[0073] Specifically, one or more of the third driver 16, the first driver 17, and the second driver 18 is a piezoelectric motor. The piezoelectric motor is small in size and can effectively reduce the overall volume of the camera mechanism.

[0074] The third driver 16 is installed on the base 10 and is in transmission connection with the support base 11. The third driver 16 is used to drive the support base 11 to move up and down. The first driver 17 is installed on the support base 11 and is in transmission connection with the first adjustment base 12. The first driver 17 is used to drive the first adjustment base 12 to rotate forward and backward. The second driver 18 is installed on the first adjustment base 12 and is in transmission connection with the second adjustment base 13. The second driver 18 is used to drive the second adjustment base 13 to rotate left and right.

[0075] Specifically, the base 10 is provided with a power supply, a controller, and a main board (PCBA), and the power supply and control components are arranged on the main board (PCBA) installed inside the electronic device. The third driver 16, the first driver 17, the second driver 18, the second camera 14, and the first camera 15 are electrically connected to the main board through a flexible printed circuit (FPC), respectively, and the main board is used to receive, feedback data and control the third driver 16, the first driver 17, the second driver 18, the second camera 14, and the first camera 15. The main board has a power supply and a controller. The flexible printed circuit board passes through the via hole inside the camera mechanism and enters the interior of the electronic device. The flexible printed circuit board forms a folding area inside the electronic device to achieve low-resistance lifting and lowering of the camera mechanism.

[0076] In one embodiment, the third driver 16 includes a first mounting seat 161, a screw rod 162, a lifting seat 163, and a motor 166. The first mounting seat 161 is mounted on the machine base 10, the screw rod 162 is rotatably mounted on the first mounting seat 161, the motor 166 is mounted on the first mounting seat 161 and is in transmission connection with the screw rod 162, and the lifting seat 163 is slidably mounted on the screw rod 162, and the lifting seat 163 is driven to move up and down by the rotation of the screw rod 162. The lifting seat 163 is connected to the support seat 11, thereby driving the support seat 11 to move up and down.

[0077] Optionally, the third driver 16 further includes a connecting rod 164 and a spring 165; one end of the connecting rod 164 is connected to the support seat 11, and the other end of the connecting rod 164 is provided with a limit block 167, the limit block 167 is sleeved on the connecting rod 164, the spring 165 is sleeved on the connecting rod 164 and clamped between the support seat 11 and the limit block 167, and the connecting rod 164 is installed on the lifting seat 163. When the lifting seat 163 moves upward, the lifting seat 163 pushes the limit block 167 to move upward, and the spring 165 is squeezed and pushes the support seat 11 to move upward. The spring 165 can play a buffering role to avoid a rigid connection between the lifting seat 163, the connecting rod 164, and the support seat 11. When the lifting seat 163 moves downward, the lifting seat 163 pushes the screw at the lower end of the connecting rod 164, thereby driving the support seat 11 to move downward.

[0078] Preferably, a second magnet 21 is mounted on the support base 11. A Hall sensor is disposed in the base 10, and the relative position of the support base 11 can be located through the induction of the Hall sensor and the second magnet 21.

[0079] Optionally, the first driver 17 includes a gear mounted on the first pivot 19 and a rack mounted on the support seat 11; the rack is meshed with the gear, a hook plate is provided at the lower end of the rack, and an anti-dropping block is provided on the machine base 10 on the moving path of the hook plate. The support seat 11 rises and falls but does not flip. When the support seat 11 rises to a certain height, the hook plate abuts against the anti-dropping block, the rack cannot rise with the support seat 11, the rack and the gear generate relative motion, and the rack drives the gear to rotate, thereby realizing the flipping of the first adjustment seat 12.

[0080] like Figures 6 to 9 For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Fig. 9 The projection direction is consistent with the front and back directions mentioned below. Fig. 9 The right and left directions of the Fig. 9 The up and down directions are consistent.

[0081] The piezoelectric motor includes a base 180, an elastic member 182 mounted on the base 180, an output member 181 rotatably mounted on the base 180, a piezoelectric block 183, and a friction head 184 disposed on the piezoelectric block 183 and used to drive the output member 181 to rotate. The elastic member 182 is a bilaterally symmetrical structure. When a voltage is input to the piezoelectric block 183, the piezoelectric block 183 drives the friction head 184 to move along an elliptical trajectory, and the friction head 184 rubs against the output member 181, thereby driving the output member 181 to rotate.

[0082] The output member 181 is in transmission connection with the support seat 11 or the first adjustment seat 12 or the second adjustment seat 13, and the elastic member 182 is connected with the piezoelectric block 183 so that the friction head 184 has a tendency to abut against the output member 181. The elastic member 182 is assembled on the base 180, and is used to limit the piezoelectric block 183 and give the piezoelectric block 183 a thrust in the direction of the output member 181. When a voltage is input to the piezoelectric block 183, the elastic member 182 provides support and elastic force for the piezoelectric block 183, and the elastic member 182 pushes the friction head 184 on the piezoelectric block 183 forward to abut against the output member 181. When a voltage is input to the piezoelectric block 183, the friction head 184 moves along an elliptical trajectory and drives the output member 181 to rotate. The friction head 184 is made of zirconium oxide or aluminum oxide ceramics. The friction head 184 is bonded to the central area of ​​one end of the piezoelectric block 183. The piezoelectric block 183 receives the excitation voltage through the conductive spring and drives the friction head 184 to vibrate, thereby driving the drive output member 181 to rotate. The piezoelectric motor of the present invention has a simple structure and a small size, and can effectively reduce the overall volume of the camera mechanism.

[0083] In one embodiment, the elastic member 182 includes a support frame 1821 and a first elastic frame 1822. The piezoelectric block 183 is mounted on the support frame 1821, and the support frame 1821 is provided with a slide groove 1826. One end of the piezoelectric block 183 provided with a friction head 184 is slidably arranged in the slide groove 1826, and one end of the piezoelectric block 183 away from the friction head 184 is connected to the first elastic frame 1822. The support frame 1821 is mounted on the base 180 to provide support for the piezoelectric block 183. The piezoelectric block 183 is located between the first elastic frame 1822 and the output member 181, and the first elastic frame 1822 is mounted on the support frame 1821. The first elastic frame 1822 abuts against the piezoelectric block 183 so that the friction head 184 has a tendency to abut against the output member 181. The first elastic frame 1822 is used to limit the piezoelectric block 183 and give the piezoelectric block 183 a thrust in the direction of the output member 181. The friction head 184 is in contact with the output member 181. When the friction head 184 moves along an elliptical trajectory and pushes the output member 181 to rotate under the drive of the piezoelectric block 183, the reaction force of the output member 181 on the friction head 184 acts on the first elastic frame 1822. The elastic force of the first elastic frame 1822 is used to continuously push the friction head 184 to contact the output member 181 and drive the output member 181 to rotate, thereby realizing continuous rotation of the output member 181.

[0084] Optionally, the elastic member 182 further includes a second elastic frame 1823 and a third elastic frame 1824. The second elastic frame 1823 and the third elastic frame 1824 are both mounted on the support frame 1821 and symmetrically arranged on both sides of the piezoelectric block 183. The piezoelectric block 183 is clamped between the second elastic frame 1823 and the third elastic frame 1824. The second elastic frame 1823 and the third elastic frame 1824 are separated on the left and right sides of the piezoelectric block 183 to prevent the piezoelectric block 183 from moving left and right, and ensure that the piezoelectric block 183 applies thrust in the direction of the output member 181.

At present, the motor used in the camera mechanism of electronic equipment is still a stepper rotor motor, and the driving force output by the stepper rotor motor is proportional to its own size. When the driving force of the stepper rotor motor is increased, the thickness of the electronic equipment will increase. Therefore, by replacing the stepper rotor motor with a piezoelectric motor, the driving force of the motor can be increased while avoiding the excessive thickness of the electronic equipment.

The grounding electrode layer 18306 is a common electrode layer for the first piezoelectric layer 18301 and the second piezoelectric layer 18302, so as to reduce the thickness of the piezoelectric block, thereby reducing the volume of the piezoelectric motor.

[0099] The first electrode portion 18303 is located in the first electrode area 183071 or the second electrode area 183072, the second electrode portion 18304 is located in the third electrode area 183081 or the fourth electrode area 183082, and the third electrode portion 18305 is located in the ground electrode layer 18306. The present invention only requires two driving electrodes and one grounding electrode to realize the positive and negative driving output of the piezoelectric motor, the two driving electrodes are respectively connected to the first electrode portion 18303 and the second electrode portion 18304, and the grounding electrode is connected to the third electrode portion 18305.

[0100] Optionally, the friction head 184, the fourth electrode area 183082 and the first electrode area 183071 are arranged at intervals in a direction away from the output member 181, the second electrode area 183072 and the third electrode area 183081 are arranged at intervals in a direction away from the output member 181, the first electrode area 183071 and the third electrode area 183081 are arranged at intervals, and a contact portion abutting against the elastic member 182 is formed between the first electrode area 183071 and the third electrode area 183081, the fourth electrode area 183082 and the second electrode area 183072 are arranged at intervals, and an output portion is formed between the fourth electrode area 183082 and the second electrode area 183072, and the friction head 184 is installed on the output portion. The first electrode area 183071 and the third electrode area 183081 are arranged at intervals from left to right, and the fourth electrode area 183082 and the second electrode area 183072 are arranged at intervals from left to right. The first electrode area 183071 and the fourth electrode area 183082 are arranged at intervals from back to front, and the third electrode area 183081 and the second electrode area 183072 are arranged at intervals from back to front. The friction head 184 is installed on the central area of ​​the front end surface of the piezoelectric block 183 and is located at the output part between the fourth electrode area 183082 and the second electrode area 183072. The first elastic frame 1822 of the elastic member 182 abuts against the abutment part. The axis of the output member, the abutment part, the friction head, the gap between the first electrode area 183071 and the third electrode area 183081, the gap between the first electrode area 183071 and the third electrode area 183081, and the first elastic frame 1822 of the elastic member 182 are all located on the same straight line and are arranged in sequence along the direction away from the output member. When voltage is input to the first electrode part 18303 or the second electrode part 18304, under the restriction of the elliptical motion of the first piezoelectric layer 18301 and the second piezoelectric layer 18302 of the piezoelectric block and the first elastic frame 1822 of the elastic member 182, the friction head 184 drives the turntable 1811 to rotate counterclockwise or clockwise.

[0101] Optionally, there are multiple first input electrode layers 18307, piezoelectric combination layers 18311, and second input electrode layers 18308, and the first input electrode layers 18307 and the second input electrode layers 18308 are alternately stacked along the rotation axis direction of the output member 181, and piezoelectric combination layers 18311 are provided between adjacent first input electrode layers 18307 and second input electrode layers 18308. In this way, the first piezoelectric layers 18301 and the second piezoelectric layers 18302 of the multiple piezoelectric combination layers 18311 work together to improve the driving force of the piezoelectric block, and at the same time, the adjacent first piezoelectric layers 18301 and the second piezoelectric layers 18302 can share the grounding electrode layer 18306, which greatly reduces the volume of the piezoelectric block 183.

[0102] All first electrode areas 183071 or all second electrode areas 183072 are electrically connected together to form a first electrode portion 18303, all third electrode areas 183081 or all fourth electrode areas 183082 are electrically connected together to form a second electrode portion 18304, and all ground electrode layers 18306 are electrically connected together to form a third electrode portion 18305, so that each first piezoelectric layer 18301 and the second piezoelectric layer 18302 can input voltage at the same time, so that the piezoelectric block 183 as a whole generates an elliptical trajectory from top to bottom. The piezoelectric block 183 is a rectangular parallelepiped, and by setting multiple layers of the first piezoelectric layer 18301 and the second piezoelectric layer 18302, the six outer surfaces are evenly stressed, thereby ensuring the consistency of the forward and reverse rotation speed of the motor.

[0103] Specifically, the piezoelectric block of the present invention is in the shape of a rectangular parallelepiped, the length direction of the piezoelectric block of the present invention is the front-to-back direction, the thickness direction is the up-down direction, and the width direction is the left-right direction.

[0104] The length of the piezoelectric block of the present invention is greater than or equal to 5.5 mm and less than or equal to 5.85 mm, the width of the piezoelectric block is greater than or equal to 1.5 mm and less than or equal to 1.6 mm, and the thickness of the piezoelectric block is 1.4 mm. Preferably, the length, width and thickness of the piezoelectric block are 5.5X1.5mmX1.4mm or 5.85mmX1.6mmX1.4mm. The thickness of the first piezoelectric layer 18301 and the second piezoelectric layer 18302 of the piezoelectric block are both 0.04mm, and the first piezoelectric layer 18301 and the second piezoelectric layer 18302 both have 32 layers. The driving voltage of the piezoelectric block is ±3V, and the driving frequency of the piezoelectric block is 246KHz.

[0105] The fourth electrode area 183082 and the first electrode area 183071 are arranged at intervals along the direction away from the output member 181, the second electrode area 183072 and the third electrode area 183081 are arranged at intervals along the direction away from the output member 181, the first electrode area 183071 and the third electrode area 183081 are arranged at intervals, and abutting portions abutting against the elastic member 182 are formed between the first electrode area 183071 and the third electrode area 183081, the fourth electrode area 183082 and the second electrode area 183072 are arranged at intervals, and an output portion is formed between the fourth electrode area 183082 and the second electrode area 183072, and the friction head 184 is installed on the output portion. The abutting part and the output part are filled with materials such as insulating film layers. The first input electrode layer 18307 and the second input electrode layer 18308 are respectively connected to voltages. Under the limitation of the filling materials, the first piezoelectric layer 18301 and the second piezoelectric layer 18302 respectively perform more stable elliptical motions in different directions, thereby making the motion trajectory of the piezoelectric block 183 more stable and accurate.

[0106] Optionally, the front-to-back direction is perpendicular to the up-to-down direction, the front-to-back direction is the radial direction of the turntable 1811, and the up-to-down direction is the axial direction of the turntable 1811. The friction head 184, the second electrode portion 18304, the third electrode portion 18305, and the first electrode portion 18303 are arranged in sequence along the front-to-back direction, and the third electrode portion 18305 is located between the first electrode portion 18303 and the second electrode portion 18304, and the third electrode portion 18305 is located in the middle, which is convenient for grounding. Compared with the first electrode portion 18303 and the second electrode portion 18304 being adjacently arranged on one side of the third electrode portion 18305, this method can free up more space and facilitate connection to an external circuit. The third electrode portion 18305 is a normally grounded electrode. When the first electrode portion 18303 is connected to the drive circuit to work, the piezoelectric block 183 drives the friction head 184 to rotate counterclockwise, thereby driving the drive turntable 1811 to rotate clockwise. When the second electrode portion 18304 is connected to the driving circuit to work, the piezoelectric block 183 drives the friction head 184 to rotate clockwise, and then drives the driving wheel to rotate counterclockwise.

[0107] Optionally, the piezoelectric block 183 further includes a first extraction electrode layer 18312, a second extraction electrode layer 18313, and a third extraction electrode layer 18314. The first extraction electrode layer 18312, the second extraction electrode layer 18313, and the third extraction electrode layer 18314 are all n-type sleeved on each first input electrode layer 18307, each piezoelectric combination layer 18311, and each second input electrode layer 18308. The first extraction electrode layer 18312, the second extraction electrode layer 18313, and the third extraction electrode layer 18314 all have a first power connection portion located inside the piezoelectric block 183 and a second power connection portion extending outside the piezoelectric block 183.

[0108] The first power connection portion of the first extraction electrode layer 18312 is electrically connected to the first electrode portion 18303, the first power connection portion of the second extraction electrode layer 18313 is electrically connected to the second electrode portion 18304, the first power connection portion of the third extraction electrode layer 18314 is electrically connected to the third electrode portion 18305, the second power connection portion of the first extraction electrode layer 18312 is electrically connected to the first conductive sheet 185, the second power connection portion of the second extraction electrode layer 18313 is electrically connected to the second conductive sheet 186, and the second power connection portion of the third extraction electrode layer 18314 is electrically connected to the third conductive sheet 187.

[0109] In order to facilitate the first electrode part 18303, the second electrode part 18304, and the third electrode part 18305 to be connected to the first conductive sheet 185, the second conductive sheet 186, and the third conductive sheet 187, the processing technology of the first extraction electrode layer 18312, the second extraction electrode layer 18313, the third extraction electrode layer 18314 and the insulating layer is as follows: First, the upper surface and the lower surface of the piezoelectric block 183 are coated with a PI insulating layer with a thickness of 3μm to 5μm. Then the first electrode part 18303, the second electrode part 18304, and the third electrode part 18305 are led out from the left side and the right side of the piezoelectric block 183, and the side silver layer electrodes of a specified width are printed on the left side and the right side during the lead-out, and then the front silver layer electrodes electrically connected to the side silver layer electrodes are printed on the front of the piezoelectric block 183. Finally, an insulating layer is printed on the lower surface, left side and right side of the piezoelectric block 183 to protect the first piezoelectric layer 18301 and the second piezoelectric layer 18302. This method can not only improve the production efficiency of the piezoelectric block 183, but also reduce the printed silver electrode layer, so that the overall volume of the piezoelectric block 183 is updated, and the overall capacitance is lower. Compared with the traditional piezoelectric block 183, the driving voltage of the present invention is lower and safer.

[0110] The piezoelectric motor of the present invention outputs torque for rotational motion, and the output member of the rotational motion only needs to drive a small-sized turntable, which is approximately equal to the cross-sectional size of the piezoelectric block. Compared with the piezoelectric motor with horizontal motion output force, the linear motion when the horizontal motion output force is used needs to drive a long axis, and the long axis is longer than the length of the piezoelectric block. Therefore, the overall size of the piezoelectric motor with rotational motion output torque of the present invention is small, and when applied to a camera mechanism, the overall size and volume of the camera mechanism can be reduced.

[0111] In this way, both the first adjustment seat and the second adjustment seat are driven by the piezoelectric motor in this embodiment, which reduces the space requirements of traditional motors. The dimensions of the piezoelectric motor driving the first adjustment seat are 8.75mm×2.65mm×4.5mm; the dimensions of the piezoelectric motor assembly driving the second adjustment seat are 7.9mm×2.7mm×2.55mm. The dimensions of the traditional motor are 20mm×10mm×4.5mm, so the size of the piezoelectric motor in this application is much smaller than that of the traditional drive motor.

[0112] Meanwhile, the embodiment of the present application also provides an electronic device, comprising the above-mentioned camera mechanism. The camera mechanism base can be the housing of the electronic device, or can be arranged in the housing of the electronic device.

[0113] In conventional whole machine driving solutions, only one motor assembly is used to drive the lifting assembly and the flip assembly, which requires a high motor driving force. Increasing the motor driving force has to increase the overall size of the motor assembly, which limits the reduction of the thickness of the whole machine.

[0114] The camera mechanism of current electronic devices such as learning tablets only has lifting and lowering movements, and the effective shooting area is limited. Improving the effective shooting area of ​​the camera is one of the core requirements of current learning tablets. At the same time, compared with the rotor motor prepared according to the principle of electromagnetic induction, the piezoelectric motor prepared using the inverse piezoelectric effect has a simple structure, a small overall size, and high movement accuracy. Using a piezoelectric motor to drive the camera mechanism can effectively reduce the motor's demand for internal space in electronic devices.

[0115] When the camera mechanism rotates, the driving force required for the motor is about 500g. A piezoelectric motor is used to drive the camera mechanism to flip, which reduces the demand for the driving force of the stepper rotor motor, thereby reducing the size of the rotor motor assembly and optimizing the size of the entire electronic device.

[0116] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
