Description

[0001] This application is a divisional application for the patent with application date of May 26, 2020, application number 202010456341.5, and invention name of camera mounting device and control method, camera module and electronic equipment. Technical Field

[0002] The present disclosure relates to the field of mechanics, and in particular to a camera installation device and control method, a camera module, and an electronic device. Background Art

[0003] In electronic devices such as mobile phones, improving the display experience is one of the goals that manufacturers are constantly pursuing. The ever-increasing screen-to-body ratio has been accompanied by the iterative updates of electronic devices. The implementation of the pop-up camera has increased the screen-to-body ratio and has become an important configuration of electronic devices. In the current pop-up camera installation device, the camera is installed on the bracket 20. Figure 1 As shown, when the camera is not popped out and is in the retracted state, the spring 10 maintains a certain pre-pressure to ensure that the sliding member 30 and the bracket 20 do not move relative to each other during the pushing process. Figure 2 As shown, after the camera pops up and is subjected to an impact force, the guide rod 40 drives the bracket 20 to move downward and compresses the spring 10. The spring 10 deforms under pressure to absorb the impact energy, thereby preventing the sliding member 30 from being damaged by the impact. In addition to the length required for the spring 10 to buffer and absorb the impact energy and the length required for the guide rod 40 to be fixed, the length of the guide rod 40 also needs to increase the compression length of the spring 10. Therefore, due to the limitation of the compression length of the spring 10 itself, the guide rod 40 is designed to be longer. Taking an 8mm pop-up distance as an example, in addition to the fixing structure of the guide rod 40, the length of the guide rod 40 and the spring 10 to achieve buffering needs to be at least 13mm, resulting in the entire installation device taking up a large space, squeezing the placement space of other components in the electronic device, and causing the product's competitiveness to decline.

[0021] The mounting device according to any of the above embodiments;

[0022] The camera is installed on the mounting position of the bracket.

[0023] According to a third aspect of an embodiment of the present disclosure, there is provided an electronic device, including:

[0024] shell;

[0025] The camera module described in any of the above embodiments is installed in the housing;

[0026] The processor is installed in the housing and connected to the rotation drive mechanism.

[0027] According to a fourth aspect of an embodiment of the present disclosure, a control method for any of the above-mentioned installation devices is provided, comprising:

[0028] Sending a first drive instruction to the rotary drive mechanism, wherein the first drive instruction is used to trigger the rotary drive mechanism to drive the screw to rotate, so that the sliding member pressed with the screw thread rotates around the screw and moves along the setting direction of the screw, thereby driving the guide rod and the bracket to move along the setting direction of the guide rod;

[0029] Wherein, when the guide rod is impacted by an external force greater than the friction force between the clamping hole and the guide rod, the guide rod moves in the clamping hole along the setting direction of the guide rod.

[0038] The technical solutions provided by the embodiments of the present disclosure may have the following beneficial effects:

[0039] It can be seen from the above embodiments that in the installation device disclosed herein, by providing a clamping hole, the guide rod is fixed to the sliding member by utilizing the friction between the clamping hole and the guide rod. When subjected to an external force impact greater than the friction between the clamping hole and the guide rod, the guide rod can overcome the friction and move relative to the sliding member along the setting direction of the guide rod, thereby buffering the external force and reducing the damage caused by the impact of the external force. The instantaneous impulse of the guide rod of the present invention subjected to the external force decreases sharply over time, and decreases to a value less than the friction between the guide rod and the clamping hole in a short period of time. In this way, only a small space for the guide rod to move up and down needs to be reserved to achieve buffering of the external force, which reduces the space occupied compared to springs that require their own fixed installation space and telescopic space.

[0051] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0052] In the description of the present disclosure, it should be understood that the terms "up", "down", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships of the user when using the camera, and are not intended to limit the present disclosure.

[0053] Figure 3 FIG. 1 is a structural diagram of a camera mounting device according to an exemplary embodiment. Figure 3 As shown, the installation device mainly includes:

[0054] Bracket 110, having a mounting position for mounting a camera;

[0055] A guide rod 120, wherein the guide rod 120 is fixedly connected to the bracket 110;

[0056] The rotary drive mechanism 130 includes a screw rod 131 arranged in parallel with the guide rod 120;

[0057] The sliding member 140 has a clamping hole 1411 and a threaded hole 143; the guide rod 120 passes through the clamping hole 1411 and is fixed to the sliding member 140 by friction between the clamping hole 1411; the screw rod 131 passes through the threaded hole 143 and engages with the thread in the threaded hole 143;

[0058] The rotary drive mechanism 130 drives the screw 131 to rotate, and the sliding member 140 rotates around the screw 131 and moves along the setting direction of the screw 131, driving the guide rod 120 and the bracket 110 to move along the setting direction of the guide rod 120;

[0059] When impacted by an external force greater than the friction force between the clamping hole 1411 and the guide rod 120 , the guide rod 120 moves within the clamping hole 1411 along the setting direction of the guide rod 120 .

[0060] In the disclosed embodiment, the rotational motion output by the rotary drive mechanism 130 is converted into linear reciprocating motion of the slider 140 through the threaded engagement between the screw 131 and the slider 140. The guide rod 120 is secured to the slider 140 by the friction between it and the gripping hole 1411. When the driving force exerted on the slider 140 by the rotary drive mechanism 130 is less than the friction between the gripping hole 1411 and the guide rod 120, the slider 140 can drive the guide rod 120 and the bracket 110 to move along the direction in which the guide rod 120 is positioned, thereby moving the camera to the outside of the device housing containing the camera.

[0061] When subjected to an external force greater than the friction between the clamping hole 1411 and the guide rod 120, the guide rod 120 can overcome the friction between the clamping hole 1411 and the guide rod 120, and move relative to the sliding member 140 along the setting direction of the guide rod 120, thereby buffering the external force and reducing the damage caused by the impact of the external force. During the movement of the guide rod 120 relative to the sliding member 140, the guide rod 120 will not be damaged by the reaction of the maximum friction between the clamping hole 1411 and the guide rod 120. Figure 3 and Figure 4 As shown, in the disclosed embodiment, the required length for fixing the guide rod 120 includes the length of the guide rod 120 within the clamping hole 1411. Furthermore, the instantaneous impulse of the external force applied to the guide rod 120 decreases dramatically over time, and within a short period of time decreases to a value less than the friction between the guide rod 120 and the clamping hole 1411. This allows only a small amount of space for the guide rod 120 to move up and down to achieve buffering of external forces. This reduces space requirements compared to the spring 10, which requires its own fixed installation space and expansion space. Furthermore, eliminating the spring 10 also helps reduce costs.

[0062] like Figures 3 to 5 As shown, when the rotary drive mechanism 130 drives the screw 131 clockwise (or counterclockwise), the slider 140 moves upward, driving the guide rod 120 and bracket 110 upward to the outside of the device housing containing the camera, thereby enabling the camera to pop out. When the rotary drive mechanism 130 drives the screw 131 in the opposite direction, that is, counterclockwise (or clockwise), the slider 140 moves downward. At this point, the slider 140 drives the guide rod 120 and bracket 110 downward, causing the camera to retract. When the bracket 110, while carrying the camera in the pop-up state, is impacted by an external force greater than the friction between the gripping hole 1411 and the guide rod 120, the guide rod 120 overcomes the friction between the gripping hole 1411 and moves downward relative to the slider 140. The downward movement of the guide rod 120 simultaneously drives the bracket 110 downward and retracts, protecting the camera.

[0063] Generally, the rotation drive mechanism 130 includes a motor, specifically a stepping motor, which drives the screw 131 to rotate in opposite directions by rotating forward or reverse.

[0064] In order to increase the friction between the clamping hole 1411 and the guide rod 120, the inner wall of the clamping hole 1411 and / or the outer surface of the guide rod 120 may be roughened to increase the roughness of the inner wall of the clamping hole 1411 and / or the outer surface of the guide rod 120. For example, a pattern may be formed on the inner wall of the clamping hole 1411 and / or the outer surface of the guide rod 120.

[0065] like Figures 3 to 6 As shown, a threaded hole 111 is provided on the bracket 110, and a threaded section 121 is provided at the corresponding position of the guide rod 120. When the guide rod 120 passes through the threaded hole, the threaded section 121 engages with the thread in the threaded hole 111 to realize the assembly of the guide rod 120 and the bracket 110.

[0066] In a specific example, the sliding member 140 includes:

[0067] The sliding body has a holding hole 1411 and a first mounting hole arranged in parallel;

[0068] a bearing passing through the first mounting hole and fixed to the sliding body through the first mounting hole; and

[0069] The nut has a threaded hole 143 , the screw rod 131 passes through the threaded hole 143 and engages with the thread in the threaded hole 143 , and the nut is fixed in the bearing.

[0070] like Figure 3 and Figure 4 As shown, when the rotary drive mechanism 130 drives the screw 131 to rotate, the slider 140 cannot rotate and move linearly as a whole. By providing a bearing, only the nut and the inner ring of the bearing in the slider 140 rotate and move linearly in the direction of the screw 131, while the slider body and the outer ring of the bearing only maintain linear movement in the direction of the screw 131.

[0071] In other optional embodiments, the rotation drive mechanism 130 is further used to drive the sliding member 140 to move along the guide rod 120 so as to restore the sliding member 140 and the guide rod 120 to an initial relative position. At this time, the sliding member 140 moves along the direction in which the guide rod 120 is set, while the guide rod 120 does not move.

[0072] In the embodiment of the present disclosure, the rotation drive mechanism 130 not only drives the sliding member 140 to move along the setting direction of the guide rod 120 to drive the bracket 110 to realize the pop-up function, but also drives the sliding member 140 to move relative to the bracket 110 to realize the reset of the sliding member 140.

[0073] In a specific example, during the normal pop-up or retraction function, the initial relative position between the sliding member 140 and the guide rod 120 remains unchanged. As Figure 3 shown, in the initial relative position, the sliding member 140 is located at the bottom of the guide rod 120. When subjected to an external force impact greater than the frictional force between the clamping hole 1411 and the guide rod 120, the guide rod 120 drives the bracket 110 to move downward, and the initial relative position between the guide rod 120 and the sliding member 140 changes, as Figure 4 shown. At this time, due to the downward movement of the guide rod 120, the sliding member 140 does not move in position, and the sliding member 140 is located at approximately the middle position of the guide rod 120. To ensure the pop-up function of the guide rod 120 and the buffering function during the next external force impact are not affected, the rotary drive mechanism 130 can drive the sliding member 140 to overcome the frictional force between the clamping hole 1411 and the guide rod 120, so that the sliding member 140 moves downward to the bottom of the guide rod 120, restoring the initial relative position between the sliding member 140 and the guide rod 120.

[0074] Further, taking the pop-up process of the bracket 110 as an example, during the pop-up process, the first rotational speed output by the rotary drive mechanism 130 is V1, and the first torque is T1; during the process of the sliding member 140 and the guide rod 120 restoring to the initial relative position, the second rotational speed output by the rotary drive mechanism 130 is V2, and the second torque is T2. Among them, the direction of the second torque T2 is opposite to the direction of the first torque T1, and V2 < V1, then T2 > T1, and the sliding member 140 overcomes the frictional force between the clamping hole 1411 and the guide rod 120. That is: the rotary drive mechanism 130 can increase the driving force on the sliding member 140 by reducing the rotational speed and increasing the torque, so that the sliding member 140 overcomes the frictional force between the clamping hole 1411 and the guide rod 120.

[0075] The rotary drive mechanism includes a stator and a rotor. Among them, both the stator and the rotor are made of magnetic materials. The stator has multiple pairs of stator magnetic poles. After the multiple pairs of stator magnetic poles are energized in a certain order, under the action of the magnetic field generated by the stator magnetic poles, the rotor rotates forward; after the multiple pairs of stator magnetic poles are energized in the reverse order, the magnetic field generated by the stator magnetic poles makes the rotor rotate in reverse.

[0076] When not subjected to an external force impact, the rotary drive mechanism 130 drives the screw 131 to rotate, and the sliding member 140 rotates around the screw 131 and moves along the set direction of the screw 131, driving the guide rod 120 and the bracket 110 to move along the set direction of the guide rod 120. At this time, the rotary drive mechanism 130 outputs a third rotational speed V3 and a third torque T3. Among them, the magnitude of the third rotational speed is equal to the first rotational speed V1, the magnitude of the third torque T3 can be equal to the magnitude of the first torque T1, and the direction of the third torque T3 is opposite to the direction of the first torque T1.

[0077] Without limitation, the portion of the sliding member 140 forming the holding hole 1411 is a C-shaped hole.

[0078] An opening 1412 is provided on the side of the sliding member 140 to form a C-shaped clamping hole 1411. Increasing the opening 1412 can reduce the friction between the clamping hole 1411 and the guide rod 120. Conversely, reducing the opening 1412 can increase the friction between the clamping hole 1411 and the guide rod 120. By adjusting the size of the opening 1412 on the sliding member 140, the friction can be conveniently adjusted to meet the preset value. For example, the preset value of the friction can be between 280gf and 600gf. Further, the preset value of the friction can be 280gf, 290gf, 300gf, 350gf, 400gf, 500gf or 600gf. The clamping hole 1411 is set as a C-shaped semi-enclosed hole for easy installation. Those skilled in the art can also set the clamping hole 1411 as a closed hole as needed. In this case, the clamping hole 1411 is an O-shaped hole.

[0079] Furthermore, the inner wall of the portion of the sliding member 140 that forms the clamping hole 1411 can be set as an elastic inner wall. Specifically, a rubber layer can be set on the inner wall that forms the clamping hole 1411. This elastic inner wall can not only further ensure the friction between the clamping hole 1411 and the guide rod 120, but also reduce the wear on the outer surface of the guide rod 120 during the movement relative to the guide rod 120.

[0080] In other optional embodiments, the guide rod 120 is interference fit with the clamping hole 1411 of the sliding member 140 .

[0081] The inner diameter of the clamping hole 1411 is slightly smaller than the outer diameter of the sliding member 140. After the guide rod 120 is inserted into the clamping hole 1411, an interference fit is generated between the guide rod 120 and the clamping hole 1411, thereby achieving a fixed connection between the guide rod 120 and the sliding member 140.

[0082] In a specific example, Figure 5 As shown, the slider 140 includes:

[0083] The sliding body 142 has a first mounting hole and a second mounting hole 1421 arranged in parallel;

[0084] The bearing passes through the first mounting hole and is fixed to the sliding body 142 through the first mounting hole;

[0085] A nut having a threaded hole 143 , wherein the screw 131 passes through the threaded hole 143 and engages with the threads in the threaded hole 143 , and the nut is fixed in the bearing; and

[0086] The sliding ring 141 has a clamping hole 1411 inside and passes through the second mounting hole 1421 outside and is fixed on the sliding body 142 .

[0087] like Figure 3 and Figure 4 As shown, in the installation device of the disclosed embodiment, guide rod 120 is short, compact, and space-saving. When the rotary drive mechanism 130 drives the screw 131, the slider 140 cannot rotate and move linearly as a whole. By providing a bearing, only the nut and the inner ring of the bearing in the slider 140 rotate while moving linearly in the direction in which guide rod 120 is set, while the slider body 142 and the outer ring of the bearing maintain linear movement in the direction in which guide rod 120 is set.

[0088] The sliding ring 141 and the sliding body 142 may be an integral structure, for example, the two are integrally formed into an integral structure by machining or molding. For example, the sliding body 142 is a polymer material block formed by injection molding.

[0089] Alternatively, the slip ring 141 and the sliding body 142 may be physically separable split structures. Figure 5 、 Figure 7 and Figure 8 As shown, the sliding body 142 is sleeved on the outside of the slip ring 141 through the second mounting hole 1421. The slip ring 141 has a clamping hole 1411. The cross-section of the slip ring 141 is C-shaped. The guide rod 120 passes through the clamping hole 1411 to form an interference fit, thereby fixing the guide rod 120 and the slip ring 141.

[0090] Without limitation, the top and bottom of the slip ring 141 both have peripheral edges protruding radially outward along the clamping hole 1411, the top peripheral edge 1413 of the slip ring 141 is located at the top of the sliding body 142, and the bottom peripheral edge 1414 of the slip ring 141 is located at the bottom of the sliding body 142. The top peripheral edge 1413 of the slip ring 141 and the bottom peripheral edge 1414 of the slip ring 141 limit the axial movement of the sliding body 142, thereby achieving a fixed connection between the slip ring 141 and the sliding body 142.

[0091] In other optional embodiments, the installation device further includes:

[0092] The acceleration sensor is installed on the bracket 110 and is used to measure the acceleration of the bracket 110. The acceleration is used to determine the stress condition of the bracket 110 when it is impacted by an external force.

[0093] Whether the bracket 110 is subjected to external impact is determined based on whether the acceleration sensor measures acceleration.

[0094] Without limitation, the acceleration sensor includes but is not limited to a gravity acceleration sensor, which measures parameter data of gravity acceleration changes of the bracket 110 .

[0095] In other optional embodiments, the installation device further includes:

[0096] The position sensor is mounted on the bracket 110 and is used to measure the position of the bracket 110 . The position is used to determine whether the camera on the bracket 110 is located at a desired position.

[0097] The desired position includes a first desired position and a second desired position. When the camera reaches the first desired position while the rotation drive mechanism is moving the camera to the outside of the device housing containing the camera, the rotation drive mechanism 130 stops driving, and the bracket 110 stops rising. When the camera reaches the second desired position while the rotation drive mechanism is moving the camera to the inside of the device housing containing the camera, the rotation drive mechanism 130 stops driving, and the bracket 110 stops descending.

[0098] Without limitation, the position sensor includes a Hall sensor 150 .

[0099] Specifically, the mounting device also includes a magnet, which is fixed on a mounting base for fixing the rotary drive mechanism. The Hall sensor 150 senses a Hall voltage, which is proportional to the strength of the magnetic field generated by the magnet. The strength of the magnetic field is a function of position. The Hall voltage sensed by the Hall sensor 150 can reflect the position of the bracket 110 on which the Hall sensor 150 is installed. For example: the Hall voltage sensed by the Hall sensor 150 gradually increases, indicating that the bracket 110 is getting closer and closer to the magnet. Since the magnet is located below the mounting device, at this time, the bracket 110 is in a retraction process; the Hall voltage sensed by the Hall sensor 150 becomes smaller and smaller, indicating that the bracket 110 is getting farther and farther from the magnet. At this time, the bracket 110 is in an ejection process.

[0100] The present disclosure also provides a camera module, comprising:

[0101] The mounting device according to any of the above embodiments;

[0102] The camera is installed on the mounting position of the bracket 110.

[0103] The camera is fixed on the bracket 110. When the rotation drive mechanism 130 is driven, the bracket 110 drives the camera to pop out or retract.

[0104] The present disclosure also provides an electronic device, comprising:

[0105] shell;

[0106] The camera module described in any of the above embodiments is installed in the housing;

[0107] The processor is installed in the housing and connected to the rotation drive mechanism 130 .

[0108] When the rotary drive mechanism moves the camera to the outside of the device housing containing the camera, the camera is exposed outside the housing, realizing a pop-up function, and the camera can be used to take photos or videos. If the pop-up camera is impacted by an external force greater than the friction between the clamping hole 1411 and the guide rod 120, the guide rod 120 drives the bracket 110 and the camera back into the housing, where they are protected.

[0109] In a specific example, the housing has space for accommodating a camera and a mounting device. The camera can be front-mounted or rear-mounted. When shooting is required, the rotating drive mechanism 130 drives the sliding member 140 to move the guide rod 120, the bracket 110 and the camera upward, so that the camera pops out.

[0110] The processor can send a first drive instruction to the rotation drive mechanism 130, wherein the first drive instruction is used to trigger the rotation drive mechanism 130 to drive the screw 131 to rotate, and the sliding member 140 threadedly pressed with the screw 131 rotates around the screw 131 and moves along the setting direction of the screw 131, driving the guide rod 120 and the bracket 110 to move along the setting direction of the guide rod 120, and the camera pops out. Figure 3 This is the state of the installation device before the rotation drive mechanism 130 executes the first drive instruction.

[0111] After the rotary drive mechanism moves the camera to the outside of the device housing containing the camera, when it is impacted by an external force greater than the friction force between the clamping hole 1411 and the guide rod 120, as shown in FIG. Figure 4 As shown, the guide rod 120 moves in the holding hole 1411 along the setting direction of the guide rod 120, and the camera retracts into the housing.

[0112] Furthermore, the processor receives the acceleration of the bracket 110, and when it determines based on the acceleration that the external force impact on the bracket 110 is greater than the friction between the clamping hole 1411 of the sliding member 140 in the installation device and the guide rod 120, it outputs a second drive instruction to the rotation drive mechanism 130; wherein, the second drive instruction is used to trigger the rotation drive mechanism 130 to drive the sliding member 140 to move along the screw 131 in the installation device, so that the sliding member 140 and the guide rod 120 are restored to their initial relative position.

[0113] In other optional embodiments, the processor receives the position of the bracket 110 of the mounting device;

[0114] Based on the position, determining whether the bracket 110 is located at the desired position;

[0115] When the bracket 110 is located at the desired position, a third driving instruction is output to the rotation driving mechanism 130 , and the third driving instruction is used to trigger the rotation driving mechanism 130 to stop driving.

[0116] In practical applications, the rotation drive mechanism 130 includes a motor and a chip, and the chip is used to control the mechanical movement of the motor. Figure 9 As shown, after receiving the eject command input by the user, the processor sends a first drive command to the chip of the rotation drive mechanism 130. After receiving the first drive command, the chip controls the motor to rotate the screw 131. The slider 140, which is threadedly engaged with the screw 131, moves along the set direction of the screw 131, driving the guide rod 120 and the bracket 110 from inside the housing to outside the housing along the set direction of the guide rod 120. When subjected to an external force greater than the friction between the clamping hole 1411 and the guide rod 120, the guide rod 120 moves within the clamping hole 1411 along the set direction of the guide rod 120 and into the housing. The initial relative position between the guide rod 120 and the sliding member 140 changes. At the same time, the processor receives the acceleration of the bracket 110 measured by the acceleration sensor, and determines based on the acceleration that the external force impact on the bracket 110 is greater than the friction between the clamping hole 1411 of the sliding member 140 in the installation device and the guide rod 120. The second drive instruction is output to the chip of the rotation drive mechanism 130. After receiving the second drive instruction, the chip controls the motor to reduce the speed and increase the torque to restore the sliding member 140 and the guide rod 120 to their initial relative position.

[0117] In the embodiments of the present disclosure, electronic devices include but are not limited to mobile phones, tablet computers, laptop computers, televisions, wearable devices, etc.

[0118] The present disclosure further provides a method for controlling the installation device according to any of the above embodiments, comprising:

[0119] Sending a first drive instruction to the rotation drive mechanism 130, wherein the first drive instruction is used to trigger the rotation drive mechanism 130 to drive the screw 131 to rotate, so that the sliding member 140 threadedly engaged with the screw 131 rotates around the screw 131 and moves along the setting direction of the screw 131, thereby driving the guide rod 120 and the bracket 110 to move along the setting direction of the guide rod 120;

[0120] When impacted by an external force greater than the friction force between the clamping hole 1411 and the guide rod 120 , the guide rod 120 moves within the clamping hole 1411 along the setting direction of the guide rod 120 .

[0121] Specifically, after receiving the eject command from the user, a first drive command is sent to the rotation drive mechanism 130. This first drive command is used to drive the camera to move. When the camera is moved outside the housing, if it is impacted by an external force greater than the friction between the gripping hole 1411 and the guide rod 120, the guide rod 120 overcomes the friction between the gripping hole 1411 and the guide rod 120 and moves downward in the direction in which the guide rod 120 is set, thereby buffering the external force and protecting the camera.

[0122] In other optional embodiments, the control method further includes:

[0123] receiving an acceleration of the bracket 110 of the mounting device;

[0124] When it is determined based on the acceleration that the external force impact on the bracket 110 is greater than the friction between the clamping hole 1411 of the sliding member 140 in the installation device and the guide rod 120, a second drive instruction is output to the rotation drive mechanism 130; wherein, the second drive instruction is used to trigger the rotation drive mechanism 130 to drive the sliding member 140 to move along the screw 131 in the installation device, so that the sliding member 140 and the guide rod 120 are restored to their initial relative position.

[0125] The acceleration can be measured by an acceleration sensor. When the bracket 110 is subjected to external impact such as falling or collision, the acceleration sensor measures the acceleration of the bracket 110 in real time.

[0126] When subjected to an external force greater than the friction between the gripping hole 1411 and the guide rod 120 in the popped-out state, the guide rod 120 moves downward in the direction in which the guide rod 120 is set, while the slider 140 remains stationary, causing the initial position between the guide rod 120 and the slider 140 to change. The second drive command causes the slider 140 to overcome the friction between the slider 140 and the guide rod 120, move downward, and restore the initial relative position between the slider 140 and the guide rod 120.

[0127] In other optional embodiments, the first drive instruction and the second drive instruction both include the rotational speed and torque output by the drive mechanism; wherein, the rotational speed of the first drive instruction is greater than the rotational speed of the second drive instruction; the torque of the first drive instruction is less than the torque of the second drive instruction, and the torque direction of the first drive instruction is opposite to the torque direction of the second drive instruction.

[0128] When the relative bracket 110 pops out, the rotation drive mechanism 130 outputs a rotation speed V1 and a torque T1. When the second drive instruction resets the sliding member 140, the rotation drive mechanism 130 outputs a rotation speed V2 lower than V1 and a torque T2 greater than T1, and the direction of the torque T2 is downward, opposite to the direction of the upward torque T1.

[0129] In other optional embodiments, the control method further includes:

[0130] the position of the bracket 110 for receiving the mounting device;

[0131] Based on the position, determining whether the bracket 110 is located at the desired position;

[0132] When the bracket 110 is located at the desired position, a third driving instruction is output to the rotation driving mechanism 130 , and the third driving instruction is used to trigger the rotation driving mechanism 130 to stop driving.

[0133] The position of bracket 110 can be measured by a position sensor. The position measured by the position sensor is transmitted to a processor. When the processor determines that the camera is in the desired position, it outputs a third drive instruction to the chip of rotation drive mechanism 130. After receiving the third drive instruction, the chip of rotation drive mechanism 130 controls the motor to stop rotating. The desired position includes a first desired position and a second desired position. The first desired position corresponds to the highest position of the camera when moving toward the outside of the electronic device housing, and the second desired position corresponds to the lowest position of the camera when moving toward the inside of the electronic device housing.

[0134] Specifically, when there is no external force impact, a first drive instruction is sent to the rotation drive mechanism 130. The first drive instruction is used to trigger the rotation drive mechanism 130 to drive the screw 131 to rotate. The sliding member 140 threadedly pressed with the screw 131 rotates around the screw 131 and moves along the setting direction of the screw 131, driving the guide rod 120 and the bracket 110 to rise and move along the setting direction of the guide rod 120 to the outside of the housing of the electronic device, that is, the camera pops up. During this pop-up process, when the camera reaches the first desired position, a third drive instruction is output to the rotation drive mechanism 130, the rotation drive mechanism 130 stops driving, and the bracket 110 no longer rises and moves.

[0135] In addition, a fourth drive instruction is sent to the rotation drive mechanism 130, and the fourth drive instruction is used to trigger the rotation drive mechanism 130 to drive the screw 131 to rotate. The sliding member 140 threadedly pressed with the screw 131 rotates around the screw 131 and moves along the setting direction of the screw 131, driving the guide rod 120 and the bracket 110 to descend and move along the setting direction of the guide rod 120 to the inner side of the housing of the electronic device, that is, the bracket 110 retracts. During the retraction process, when the bracket 110 reaches the second desired position, the third drive instruction is output to the rotation drive mechanism 130, the rotation drive mechanism 130 stops driving, and the bracket 110 no longer descends.

[0136] Furthermore, the first drive instruction and the fourth drive instruction both include the rotational speed and torque output by the rotational drive mechanism 130; wherein, the rotational speed of the first drive instruction is equal to the rotational speed of the fourth drive instruction; the torque of the first drive instruction is equal to the torque of the fourth drive instruction, and the torque direction of the first drive instruction is opposite to the torque direction of the fourth drive instruction.
