Description

Technical Field

[0001] The present application relates to the technical field of photographing devices, and particularly to a motor, a camera module, and an electronic device. Background Art

[0002] In recent years, with the development of optical imaging technology, people's requirements for the photographing function of portable electronic devices have become increasingly high, and it is required that the camera modules configured in the electronic devices can achieve photographing at different focal lengths, such as telephoto photographing and macro photographing.

[0003] Generally, the camera module realizes the switching of different focal length photographing modes by driving the prism to move. However, since the current camera module has no self-locking ability or has a poor self-locking ability, the reliability is poor, and there is an easy risk of impact in different focal length photographing modes. Summary of the Invention

[0004] The present application provides a motor, a camera module, and an electronic device. The motor includes a fixed base, a moving stage, a driving component, and a self-locking component. Through the coaxial bilateral output design of the self-locking component, the stability of the locking between the moving stage and the fixed base is improved, and the simultaneous locking and unlocking of both sides of the self-locking component can be realized, which is beneficial to improving the smoothness of locking and unlocking and reducing the impact risk.

[0005] In a first aspect, the present application provides a motor. The motor includes a fixed base, a moving stage, a driving component, a self-locking component, and a stopper; the self-locking component is fixedly installed on the moving stage, and the self-locking component includes a driving member, a first telescopic member, and a second telescopic member. The driving member includes a body and an output shaft. The output shaft includes an opposite first end and a second end. The output shaft penetrates through the body, and the first end and the second end of the output shaft are respectively exposed on opposite sides of the body. The first telescopic member is connected to the first end of the output shaft, and the second telescopic member is connected to the second end of the output shaft. The body is used to drive the output shaft to rotate to drive the first telescopic member and the second telescopic member to simultaneously expand and contract; the fixed base is provided with a first locking hole and a second locking hole, the first locking hole and the second locking hole are oppositely arranged and are located on opposite sides of the driving member. The driving component is used to drive the moving stage to move relative to the fixed base to align the first telescopic member with the first locking hole and the second telescopic member with the second locking hole; when the motor is in a locked state, the first telescopic member extends into the first locking hole, the second telescopic member extends into the second locking hole, and the stopper blocks the first telescopic member from continuing to move towards the first locking hole; when the motor is in an unlocked state, the first telescopic member is located outside the first locking hole, and the second telescopic member is located outside the second locking hole.

[0006] In the present application, by inserting the first telescopic member into the first locking hole and the second telescopic member into the second locking hole, physical mechanical stable self-locking can be achieved, that is, the self-locking assembly can lock the moving stage and the fixed base, thereby achieving the self-locking of the motor, and further making the lens stable, which is beneficial to improving the reliability of the lens when the electronic device shakes or drops. For example, when the first telescopic member extends into the first locking hole and the second telescopic member extends into the second locking hole to lock the moving stage and the fixed base, the stability of the lens when the electronic device is shaken by the user's hand and the stability of the lens when the electronic device drops can be ensured. For example, the stability of the lens when the electronic device drops from a height of 1 meter, or 1.2 meters, or 1.4 meters, or higher.

[0007] In the present application, since the driving member can drive the first telescopic member and the second telescopic member to expand and contract simultaneously, so as to realize the first telescopic members moving away from each other or moving towards each other simultaneously, the simultaneous locking and unlocking of both sides of the self-locking assembly can be achieved, which is beneficial to improving the smoothness of locking and unlocking.

[0008] In the present application, by providing a stop member, the limit of the first telescopic member in the locked state can be realized, so as to prevent the first telescopic member from continuing to move towards the first locking hole under external forces such as dropping and impact, to prevent damage to the first telescopic member, the second telescopic member and the driving member, and also to prevent collision between the first telescopic member and the detection chip and damage to the detection chip. Designed in this way, the problem that the output torque of the driving member is small due to the limited installation space of the motor and the self-locking between the driving member and the first telescopic member and the second telescopic member cannot be achieved is overcome, and the problem that the detection chip cannot be powered on all the time to perform closed-loop detection on the position of the first screw due to power consumption limitations is also overcome. Therefore, the setting of the stop member can not only protect the components in the motor and improve the overall anti-external impact ability of the motor, but also reduce the power consumption through physical stop to save power.

[0009] In some possible implementation manners, the first telescopic member includes a first screw and a first nut; the first screw is connected between the first end of the output shaft and the first nut, the first screw passes through the first nut and is threadedly connected to the first nut; the first nut is fixedly installed on the moving stage; the driving member is used to drive the first screw to rotate relative to the first nut to drive the first screw to extend or retract relative to the moving stage; when the motor is in the locked state, the first screw extends into the first locking hole, and the stop member blocks the first screw from continuing to extend relative to the first moving stage.

[0010] In this implementation, the driving member can drive the first screw to rotate relative to the first nut, so that the first screw can move relative to the first nut in the third direction to achieve extension and retraction. Since a nut connection is adopted between the first screw and the first nut in the first telescopic member, after the driving member stops driving, the first telescopic member can stably stay at any position, that is, the power-off locking of the self-locking assembly is realized, which is beneficial to energy saving. Since the power-off locking is realized without the cooperation of external forces, when the driving member is powered on, no external force other than the frictional force between the first screw and the first nut needs to be overcome, reducing the driving force required to drive the first screw to move relative to the first nut, which is beneficial to energy saving. In addition, since the driving member drives the first screw to rotate, and the cooperation between the first screw and the first nut can realize the conversion of rotation into linear motion, when the self-locking assembly is in the power-off locking state, applying a corresponding rotational force to the first screw is required to break the locking of the self-locking assembly, which makes it difficult to break the locked state of the self-locking assembly and improves the stability of the self-locking assembly during power-off locking.

[0011] In some possible implementations, the first screw includes a first part and a second part. The first part of the first screw is closer to the driving member than the second part of the first screw. The first part of the first screw is provided with a first external thread, and the maximum outer diameter of the second part of the first screw is smaller than the maximum outer diameter of the first part of the first screw; the stop member is installed on the moving stage, the stop member is located on the side of the first nut away from the driving member, the stop member has a first through hole, and the inner diameter of the first through hole is larger than the maximum outer diameter of the second part of the first screw and smaller than the maximum outer diameter of the first part of the first screw; when the motor is in the locked state, a part of the second part of the first screw extends into the first locking hole.

[0012] In this implementation, the first screw realizes the threaded connection with the first nut through the first part and realizes the cooperation with the first locking hole through the second part. Through the setting of the stop member, the second part of the first screw can pass through the first through hole of the stop member, so as to realize the extension and retraction of the first screw relative to the first locking hole, so as to realize the locking and unlocking of the motor. In addition, the stop member can form a limit on the first part of the first screw at the first through hole to prevent the first part of the first screw from passing through the first through hole. With such a setting, when the second part of the first screw extends into the first locking hole and the motor is in the locked state, a stable stop limit can be provided for the motor to prevent the first screw from further moving towards the first locking hole to protect components such as the driving member and the detection chip.

[0013] In some possible implementation manners, when the motor is in an unlocked state, at least a part of the second part of the first screw is located in the first through hole, so as to prevent the first screw from retracting too much, thereby avoiding the situation that the first screw is blocked by the stopper after retracting due to the deviation existing during the assembly of the first nut, the first screw and the stopper, and further avoiding the jamming of the first screw.

[0014] In some possible implementation manners, a first transmission groove is provided on the end surface of the first part of the first screw away from the second part of the first screw; the self-locking assembly further includes a first transmission shaft, the first transmission shaft includes a first part and a second part, the first part of the first transmission shaft is fixedly connected to the first end of the output shaft, at least a part of the second part of the first transmission shaft is located in the first transmission groove, and the second part of the first transmission shaft abuts against the side wall of the first transmission groove under the drive of the output shaft to drive the first screw to rotate.

[0015] In this implementation manner, through the setting of the first transmission shaft, it can play a role in connecting the first end of the output shaft and the first telescopic member. Since the output shaft is the self-structure of the driving member, the output of the driving member may be limited by the shape of the output shaft. By designing the shape of the first transmission shaft, the transmission connection form of the driving member can be changed, so that the driving member can better match the first telescopic member.

[0016] In this implementation manner, the driving member can drive the first transmission shaft to rotate through the output shaft, the rotation of the first transmission shaft can drive the first screw to rotate relative to the first nut, and the first screw can move relative to the first nut along the third direction under the drive of the first transmission shaft to achieve extension and retraction. Since a nut connection is adopted between the first screw and the first nut in the first telescopic member, after the driving member stops driving, the first telescopic member can stay stably at any position, that is, the power-off locking of the self-locking assembly is realized, which is beneficial to energy saving. Since the power-off locking is realized without the cooperation of external force, when the driving member is powered on, no external force other than the frictional force between the first screw and the first nut needs to be overcome, reducing the driving force required to drive the first screw to move relative to the first nut, which is beneficial to energy saving. In addition, since the driving member drives the first screw to rotate through rotation output, and the cooperation between the first screw and the first nut can realize the conversion of rotation into linear motion, when the self-locking assembly is in the power-off locking state, applying a corresponding rotational force to the first screw is required to break the locking of the self-locking assembly, which makes it difficult to break the locking state of the self-locking assembly and improves the stability of the self-locking assembly during power-off locking.

[0017] In some possible implementation manners, when the motor is in an unlocked state, the second part of the first transmission shaft abuts against the bottom wall of the first transmission groove. At this time, the end surface of the second part of the first transmission shaft forms a limit when the first screw retracts, which can prevent the first screw from retracting excessively.

[0018] In some possible implementation manners, the outer diameter of the first part of the first transmission shaft is greater than the outer diameter of the second part of the first transmission shaft. A first limiting surface is formed at the connection of the first part and the second part of the first transmission shaft, and the first limiting surface is exposed from the second part of the first transmission shaft. When the motor is in the unlocked state, the first limiting surface abuts against the end surface of the first part of the first screw rod away from the second part of the first screw rod. At this time, the first limiting surface forms a limit when the first screw rod retracts, and can prevent the first screw rod from retracting excessively.

[0019] In some possible implementation manners, the first nut has a first threaded hole, and the first screw rod is arranged through the first threaded hole; a stop member is arranged at the end of the first screw rod close to the driving member, and the outer diameter of the stop member is greater than the inner diameter of the first threaded hole; when the motor is in the locked state, the stop member abuts against the first nut.

[0020] In this implementation manner, by arranging the stop member at the end of the first screw rod, the size relationship between the stop member and the first threaded hole of the first nut can be used to form a limit, so as to prevent the first screw rod from protruding too much relative to the first nut. When the second part of the first screw rod extends into the first locking hole and the motor is in the locked state, it can provide a stable stop limit for the motor, prevent the first screw rod from further moving towards the first locking hole, and protect components such as the driving member and the detection chip.

[0021] In some possible implementation manners, the stop member and the first screw rod are of an integral structure, so as to improve the overall structural stability of the first screw rod and the stop member, which is beneficial to improving the strength of the limit formed between the stop member and the first nut, and further beneficial to improving the reliability when the motor is in the locked state.

[0022] In some possible implementation manners, a first transmission groove is provided on the end surface of the first screw rod facing the driving member; the self-locking assembly further includes a first transmission shaft, which includes a connected first part and a second part. The first part of the first transmission shaft is fixedly connected to the first end of the output shaft, and the second part of the first transmission shaft has a first transmission surface, and the first transmission surface is located in the first transmission groove; the first transmission surface abuts against the side wall of the first transmission groove under the rotation of the first transmission shaft to drive the first screw rod to rotate.

[0023] In this implementation manner, through the design of the first transmission groove, a transmission connection can be formed between the first transmission shaft and the first screw rod, so as to form a transmission chain. The first end of the output shaft can drive the first screw rod to rotate by driving the first transmission shaft to rotate.

[0024] In some possible implementation manners, a first installation groove is provided on the end surface of the first part of the first transmission shaft, the first end of the output shaft is installed in the first installation groove, and the opposite sides of the first end of the output shaft are fixedly connected to the side walls of the first installation groove.

[0025] In this implementation manner, by fixedly connecting the opposite sides of the first end of the output shaft to the side walls of the first mounting groove, it is beneficial to improve the balance of the connection between the first end of the output shaft and the first transmission shaft, making the assembly connection between the first end of the output shaft and the first transmission shaft more stable and capable of avoiding the problem of the first transmission shaft tilting during assembly.

[0026] Among them, the opposite sides of the first end of the output shaft can be welded to the side walls of the first mounting groove. For example, laser welding can be used between the first end of the output shaft and the side walls of the first mounting groove. After the first end of the output shaft is inserted into the first mounting groove, the first part of the first transmission shaft can be penetrated by laser, and the first welding material can be used to achieve the welding between the first end of the output shaft and the first part of the first transmission shaft.

[0027] In some possible implementation manners, there is a first assembly gap between the first transmission surface and the side wall of the first transmission groove, and the size d0 of the first assembly gap satisfies: 0 < d0 ≤ 0.2 mm.

[0028] In this implementation manner, there can be a first assembly gap between the first transmission surface and the side wall of the first transmission groove to achieve assembly tolerance, thereby avoiding jamming during the process of the transmission shaft driving the first screw to rotate. The size d0 of the first assembly gap satisfies the above relationship, which is beneficial to form assembly tolerance, avoid jamming during the process of the first transmission shaft driving the first screw to rotate, and can also avoid excessive clearance, resulting in hysteresis in the transmission between the first transmission shaft and the first screw.

[0029] In some possible implementation manners, the second telescopic member includes a second screw and a second nut; the second screw is connected between the second end of the output shaft and the second nut, the second screw passes through the second nut and is threadedly connected to the second nut; the second nut is fixedly installed on the moving stage; the driving member is used to drive the second screw to rotate relative to the second nut to drive the second screw to extend or retract relative to the moving stage; when the motor is in the locked state, the first screw extends into the first locking hole, and the second screw extends into the second locking hole.

[0030] In this implementation manner, the driving member can drive the second transmission shaft to rotate through the output shaft. The rotation of the second transmission shaft can drive the second screw rod to rotate relative to the second nut. Driven by the second transmission shaft, the second screw rod can move relative to the second nut in the third direction to achieve extension and retraction. Since a nut connection is adopted between the second screw rod and the second nut in the second telescopic member, after the driving member stops driving, the second telescopic member can stay stably at any position, that is, the power-off locking of the self-locking assembly is realized, which is beneficial to energy saving. Since the power-off locking is realized without the cooperation of external force, when the driving member is powered on, no external force other than the frictional force between the second screw rod and the second nut needs to be overcome, reducing the driving force required to drive the second screw rod to move relative to the second nut, which is beneficial to energy saving. In addition, since the driving member drives the second screw rod to rotate, and the cooperation between the second screw rod and the second nut can realize the conversion of rotation into linear motion. Therefore, when the self-locking assembly is in the power-off locking state, a corresponding rotational force needs to be applied to the screw rod to break the locking of the self-locking assembly, which makes it difficult to break the locking state of the self-locking assembly and improves the stability of the self-locking assembly during power-off locking.

[0031] In some possible implementation manners, the first nut has a first threaded hole, a first internal thread is provided in the first threaded hole, the first screw rod has a first external thread, the first screw rod passes through the first threaded hole, and the first external thread is threadedly connected to the first internal thread; the second nut has a second threaded hole, a second internal thread is provided in the second threaded hole, the second screw rod has a second external thread, the second screw rod passes through the second threaded hole, and the second external thread is threadedly connected to the second internal thread; the thread directions of the first external thread and the second external thread are opposite, and the thread directions of the first internal thread and the second internal thread are opposite, so that the driving member can drive the first screw rod and the second screw rod on both sides to extend or retract simultaneously through the output shaft.

[0032] In some possible implementation manners, the first external thread has a first thread starting point. In a plane perpendicular to the axis of the first screw rod and passing through the first thread starting point, a first connection line is formed by connecting the first thread starting point and the center of the first screw rod. There is a first included angle between the first connection line and the axis of the first screw rod; the second external thread has a second thread starting point. In a plane perpendicular to the axis of the second screw rod and passing through the second thread starting point, a second connection line is formed by connecting the second thread starting point and the center of the second screw rod. There is a second included angle between the second connection line and the axis of the second screw rod; the difference between the first included angle and the second included angle is less than or equal to 2°.

[0033] In this implementation manner, by designing |α1 - α2| to be less than or equal to 2°, it is beneficial to ensure that under the drive of the driving member, the feed amounts of the first screw rod and the second screw rod on both sides of the driving member tend to be consistent. Wherein, α1 is the first included angle and α2 is the second included angle.

[0034] In some possible implementation manners, the first internal thread has a third thread starting point. In a plane perpendicular to the axis of the first nut and passing through the third thread starting point, a third connection line is formed by connecting the third thread starting point to the center of the first nut. There is a third included angle between the third connection line and the axis of the first nut; the second internal thread has a fourth thread starting point. In a plane perpendicular to the axis of the second nut and passing through the fourth thread starting point, a fourth connection line is formed by connecting the fourth thread starting point to the center of the second nut. There is a fourth included angle between the fourth connection line and the axis of the second nut; the difference between the third included angle and the fourth included angle is less than or equal to 2°.

[0035] In this implementation manner, by designing |α3 - α4| to be less than or equal to 2°, it is beneficial to ensure that under the drive of the driving member, the feed amounts of the first screw rod and the second screw rod on both sides of the driving member tend to be consistent. Wherein, α3 is the third included angle and α4 is the fourth included angle.

[0036] In some possible implementation manners, the pitch of the first external thread is the same as the pitch of the second external thread; and / or, the pitch of the first internal thread is the same as the pitch of the second internal thread, so that when the driving member drives the first screw rod and the second screw rod to rotate, the travel of the first screw rod relative to the first nut is the same as the travel of the second screw rod relative to the second nut, that is, the feed amounts of the first screw rod and the second screw rod are the same.

[0037] In some possible implementation manners, the motor further includes a self-locking detection component. The self-locking detection component includes a first magnet and a detection chip; the first magnet is installed at the end of the first telescopic member away from the driving member. The first magnet can move with the first telescopic member. The detection chip is installed on the fixed base, and the detection chip is arranged opposite to the first magnet.

[0038] In this implementation manner, since the first magnet is arranged opposite to the detection chip, when the first telescopic member moves relative to the first locking hole, the detection chip can detect the position of the first magnet relative to the detection chip, so as to accurately detect the relative position of the first telescopic member relative to the first locking hole, and determine whether the first telescopic member extends into the first locking hole to complete locking, or determine whether the first telescopic member disengages from the first locking hole to complete unlocking, improving the accuracy of the locking and unlocking of the motor. In addition, since the driving member drives the first telescopic member and the second telescopic member to expand and contract simultaneously, therefore, only detecting the first telescopic member to achieve closed-loop control can achieve closed-loop control of the second telescopic member, thereby improving the stability of the locking and unlocking of the moving stage and the fixed base.

[0039] In some possible implementation manners, when the motor is in a locked state, the length that the first telescopic member extends into the first locking hole is greater than or equal to 0.5 mm, so as to improve the locking stability between the moving stage and the fixed base. For example, the length that the first telescopic member extends into the first locking hole can be, but is not limited to, 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, or other values greater than 0.5 mm.

[0040] In some possible implementation manners, the motor further includes a magnetic attraction assembly, and the magnetic attraction assembly includes a second magnet and a magnetic attraction member; the second magnet is installed at the end of the second telescopic member away from the driving member, the second magnet can move along with the second telescopic member, the magnetic attraction member is installed on the fixed base, and the magnetic attraction member is arranged opposite to the second magnet.

[0041] In this implementation manner, through the design of the magnetic attraction assembly, a magnetic attraction force can be generated between the magnetic attraction member and the second magnet. In this way, when the motor is in a locked state, the magnetic attraction member magnetically attracts the second magnet, so that the second telescopic member and the fixed base are magnetically locked, which can prevent the second telescopic member from retracting due to external forces such as dropping and impact, and can improve the locking stability between the moving stage and the fixed base.

[0042] In some possible implementation manners, the moving stage has a bearing surface, the bearing surface is arranged facing away from the bottom wall of the fixed base, and the bearing surface is inclined with respect to the bottom wall of the fixed base. The bearing surface is used for bearing an optical element; the moving stage has a receiving space, and the receiving space is located between the bearing surface and the bottom wall of the fixed base, and the self-locking assembly is installed in the receiving space.

[0043] In this implementation manner, by arranging the self-locking assembly and the optical element on opposite sides of the bearing surface of the moving stage, and by receiving the self-locking assembly through the receiving space, the receiving and installation of the self-locking assembly are realized by using the self-space of the moving stage, reducing the space size occupied by the self-locking assembly additionally, improving the space utilization rate of the motor, and being beneficial to the miniaturization of the motor.

[0044] In some possible implementation manners, the moving stage has a first limiting rib and a second limiting rib. Both the first limiting rib and the second limiting rib are arranged on the inner wall of the receiving space. The first limiting rib and the second limiting rib are arranged at intervals. The first limiting rib has a V-shaped structure or a U-shaped structure, and the opening of the first limiting rib faces the opening of the receiving space. The second limiting rib has a V-shaped structure or a U-shaped structure, and the opening of the second limiting rib faces the opening of the receiving space; the machine body includes a machine shell, a first bearing and a second bearing. The first bearing is installed at the first end of the machine shell, the second bearing is installed at the second end of the machine shell, the output shaft passes through the first bearing, the machine shell and the second bearing, the first bearing is installed on the first limiting rib, and the second bearing is installed on the second limiting rib.

[0045] In this implementation, since the first limiting rib is in a V-shaped structure or a U-shaped structure, the positioning of the first bearing can be achieved. Since the second limiting rib is in a V-shaped structure or a U-shaped structure, the positioning of the second bearing can be achieved. Through the design of the first limiting rib and the second limiting rib, the overall positioning and installation of the driving member can be achieved, and the problem of tilting during the assembly of the driving member can be solved, thereby improving the stability of the self-locking assembly during operation.

[0046] In some possible implementations, the moving stage has a first limiting hole and a second limiting hole. The first limiting hole and the second limiting hole are arranged at intervals and are both communicated with the accommodating space. First end plates and second end plates are respectively installed at both ends of the fuselage. The output shaft passes through the first end plate and the second end plate. A part of the first end plate is located in the first limiting hole, and a part of the second end plate is located in the second limiting hole.

[0047] In this implementation, through the clamping of the first end plate by the first limiting hole and the clamping of the second end plate by the second limiting hole, the stability of the installation between the driving member and the moving stage can be further improved, thereby further strengthening the installation of the driving member.

[0048] In some possible implementations, the number of the first locking holes is multiple, and the number of the second locking holes is multiple. The arrangement directions of the multiple first locking holes are the same as the arrangement directions of the multiple second locking holes, and the first locking holes and the second locking holes are arranged in one-to-one correspondence and facing each other.

[0049] In this implementation, by providing a plurality of first locking holes and a plurality of second locking holes, the moving stage can be locked at different positions of the fixed base. By arranging the first locking holes and the second locking holes in one-to-one correspondence, so that at each first locking hole, the moving stage can realize simultaneous locking and unlocking on both sides through the self-locking assembly.

[0050] In some possible implementations, the driving member is a stepping motor, which is beneficial to the rotation control of the output shaft of the driving member to achieve stable rotation of the output shaft, and is also beneficial to making the feed amounts of the first screw rod and the second screw rod on both sides consistent.

[0051] In a second aspect, the present application provides a camera module. The camera module includes a lens and any one of the motors in the first aspect. The lens includes an optical element and a lens group. The optical element is mounted on the moving stage of the motor, and the lens group is located on the image side of the optical element. The optical element is used to change the light incident on the camera module in the first direction to propagate in the second direction.

[0052] In the present application, the optical element is used to change the direction of light so that the light entering through the light-transmitting hole can be reflected to the image sensor. Specifically, the optical element is used to change the light incident in the first direction to propagate in the second direction. The moving stage can drive the optical element to move relative to the fixed base to change the position of the optical element, thereby changing the corresponding light-transmitting hole of the optical element and the distance between the optical element and the lens group, and further realizing the change of the focal length of the lens of the camera module, that is, realizing the focal length switching of the lens. For example, the switching between telephoto shooting and macro shooting is realized.

[0053] In some possible implementation manners, the lens further includes a first lens group and a second lens group, and the first lens group and the second lens group are arranged at intervals; the moving stage is used to drive the optical element to move to the first position to receive the light passing through the first lens group; the moving stage is further used to drive the optical element to move to the second position to receive the light passing through the second lens group, wherein the second position and the first position are arranged at intervals in the second direction.

[0054] In this implementation manner, the moving stage drives the optical element to move so that the optical element can form lenses with different focal lengths in different positions in combination with different lenses. For example, in the first position, the first lens group, the optical element, and the lens group can form a first lens with a first focal length; in the second position, the second lens group, the optical element, and the lens group can form a second lens with a second focal length. Among them, the first focal length is different from the second focal length. Therefore, driving the optical element to move to different positions by the moving stage can realize the switching of different lenses, such as realizing the switching between the first lens and the second lens. By analogy, through the setting of more lens combinations, the switching of more focal lengths can also be realized.

[0055] In a third aspect, the present application provides an electronic device. The electronic device includes a housing and a camera module as described in any one of the second aspects, and the camera module is installed in the housing.

[0056] In the present application, since the camera module can achieve more stable locking through the design of the motor, the working stability of the camera module is improved, and further the shooting stability of the electronic device is improved. Description of the Drawings

Of course, other types of electronic devices 1000 may also adopt a similar structure, which will not be elaborated hereinafter

[0106] It can be understood that Figure 1A and Figure 1B only schematically shows some components included in the electronic device 1000. The actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 1A and Figure 1B The electronic device 1000 may also include more or fewer components compared to Figure 1A and Figure 1B more or fewer components

[0107] In some embodiments, the electronic device 1000 may include a camera module 100, a screen 200, and a housing 300. Among them, the screen 200 is used to display images, videos, etc. The screen 200 may include a light-transmitting panel 2001 and a display screen 2002. The light-transmitting panel 2001 and the display screen 2002 are stacked and fixedly connected. The light-transmitting panel 2001 is mainly used to protect the display screen 2002 and prevent dust. The material of the light-transmitting panel 2001 includes but is not limited to glass. The display screen 2002 may be a flexible display screen or a rigid display screen. For example, the display screen 2002 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a quantum dot light emitting diodes (QLED) display screen, a liquid crystal display (LCD), etc.

[0108] Exemplarily, the housing 300 is used to protect the internal electronic components of the electronic device 1000. The housing 300 may include a cover plate 3001, a frame 3002, and a decorative member 3003. The cover plate 3001 is located on the side of the display screen 2002 away from the light-transmitting panel 2001, and is stacked with the light-transmitting panel 2001 and the display screen 2002. The frame 3002 is fixed to the cover plate 3001. Exemplarily, the frame 3002 may be fixedly connected to the cover plate 3001 by adhesive. The frame 3002 may also be an integrally formed structure with the cover plate 3001, that is, the frame 3002 and the cover plate 3001 are a whole structure. The frame 3002 is located between the cover plate 3001 and the light-transmitting panel 2001. The light-transmitting panel 2001 may be fixedly adhered to the frame 3002. The light-transmitting panel 2001, the cover plate 3001, and the frame 3002 enclose an internal installation space of the electronic device 1000. The display screen 2002 is accommodated in this internal installation space. Among them, the cover plate 3001 may be made of materials such as metal, plastic, and glass. The cover plate 3001 may be a plate body made of a single material, or a plate body structure made of multiple materials and spliced by multiple plates. Among them, an installation opening 3004 is provided on the cover plate 3001, and the decorative member 3003 covers and is fixed at the installation opening 3004.

[0109] Exemplarily, the camera module 100 is used to take pictures / videos. For example, the camera module 100 is installed in the housing 300 and is located in the internal installation space of the electronic device 1000. Among them, the camera module 100 can be used as a rear camera. For example, the light incident surface of the camera module 100 faces the decorative member 3003. The decorative member 3003 is used to protect the camera module 100.

[0110] In some embodiments, the decorative member 3003 protrudes to the side of the cover plate 3001 away from the light-transmitting panel 2001. In this way, the decorative member 3003 can increase the installation space of the camera module 100 in the thickness direction of the electronic device 1000. In other embodiments, the decorative member 3003 may also be flush with the cover plate 3001 or recessed into the internal installation space of the electronic device 1000.

[0111] Among them, a light-transmitting hole 3005 is provided on the decorative member 3003. The light-transmitting hole 3005 allows light to enter the light incident surface of the camera module 100. In some other embodiments, the electronic device 1000 may not include the decorative member 3003. At this time, the installation opening 3004 is no longer provided on the cover plate 3001, and the light-transmitting hole 3005 is provided on the cover plate 3001. The light-transmitting hole 3005 allows light to enter the light incident surface of the camera module 100.

[0112] In some examples, the number of the light-transmitting holes 3005 may be multiple, and different light-transmitting holes 3005 may correspond to different lenses 201. For example, different light-transmitting holes 3005 correspond to lenses 201 with different focal lengths.

[0113] In some other examples, the number of the light-transmitting holes 3005 may be one, and different regions of the light-transmitting hole 3005 may correspond to different lenses 201. For example, different regions of the light-transmitting hole 3005 correspond to lenses 201 with different focal lengths.

[0114] It should be noted that in the embodiments hereinafter, it is schematically shown that one light-transmitting hole 3005 corresponds to one lens 201 with one focal length.

[0115] In some other embodiments, the imaging module 100 may also be used as a front camera. For example, the light incident surface of the imaging module 100 faces the light-transmitting panel 2001. An optical path avoidance structure is provided on the display screen 2002. The optical path avoidance structure allows the scene light to pass through the light-transmitting panel 2001 and then enter the light incident surface of the imaging module 100. In some other embodiments, the electronic device 1000 may further include one or more other camera modules (not shown in the figure), and the embodiments of the present application do not make strict limitations thereto.

[0116] In some embodiments, as Figure 1B shown, the electronic device 1000 may further include a circuit board 400 and an image processor 500. The circuit board 400 and the image processor 500 are located in the internal installation space of the electronic device 1000. The image processor 500 is fixed to the circuit board 400 and electrically connected to the circuit board 400. The image processor 500 is communicatively connected to the imaging module 100. The image processor 500 is configured to obtain image data from the imaging module 100 and process the image data. Among them, the communication connection between the imaging module 100 and the image processor 500 may include data transmission through electrical connection means such as wiring, or may be achieved through coupling or other means. It can be understood that the imaging module 100 and the image processor 500 may also be communicatively connected through other means capable of realizing data transmission.

[0117] In some embodiments, the electronic device 1000 may further include an analog-to-digital converter (also referred to as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the imaging module 100 and the image processor 500. The analog-to-digital converter is configured to convert the signal generated by the imaging module 100 into a digital image signal and transmit it to the image processor 500, and then the image processor 500 processes the digital image signal, and finally the image or video is displayed through the screen 200.

[0118] In some embodiments, the electronic device 1000 may further include a memory (not shown in the figure). The memory is communicatively connected to the image processor 500. After the image processor 500 processes the image digital signal, the image is transmitted to the memory so that the image can be retrieved from the memory at any time when viewing the image is required later and displayed on the screen 200. In some embodiments, the image processor 500 also compresses the processed image digital signal and then stores it in the memory to save memory space.

[0119] In some other embodiments, the electronic device 1000 may not include the screen 200 either.

[0120] It can be understood that Figure 1A and Figure 1B the installation position of the camera module 100 of the electronic device 1000 shown in the embodiments is only illustrative, and the present application does not strictly limit the installation position of the camera module 100. In some other embodiments, the camera module 100 may also be installed at other positions of the electronic device 1000. For example, the camera module 100 may be installed in the middle upper part or the upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can rotate, move or be detached relative to the terminal body, and the camera module 100 may also be provided on the auxiliary component.

[0121] Please refer to Figure 2A and Figure 2B , Figure 2A which Figure 1A is a schematic structural diagram of the electronic device 1000 shown in some embodiments when cut along line A-A; Figure 2B which Figure 1A is a schematic structural diagram of the electronic device 1000 shown in some other embodiments when cut along line A-A.

[0122] For the convenience of illustration, in the embodiments of the present application, the thickness direction (i.e., the light incident direction) of the camera module 100 is the Z-axis, the movement direction of the moving stage 2 relative to the fixed base 1 is the X-axis, and the width direction of the camera module 100 is the Y-axis to establish a rectangular coordinate system. It can be understood that in some other embodiments, other references can also be used to establish the coordinate system, which is not limited herein. Among them, the Z-axis direction is also referred to as the first direction Z, the X-axis direction is also referred to as the second direction X, and the Y-axis direction is also referred to as the third direction Y.

[0123] In some embodiments, the camera module 100 may include a motor 10 and an optical system 20. The motor 10 can be used to carry some optical devices in the optical system 20.

[0124] Exemplarily, the optical system 20 may include a lens 201 and an image sensor 202. The lens 201 may include an optical element 2011 and a lens group 2012. The optical element 2011 may be mounted on the motor 10. The optical element 2011, the lens group 2012, and the image sensor 202 are arranged at intervals along the optical path of the lens 201.

[0125] In this embodiment, the optical element 2011 is used to change the light direction so that the light entering through the light-transmitting hole 3005 can be reflected to the image sensor 202. Specifically, the optical element 2011 is used to change the light incident in the first direction Z to propagate in the second direction X.

[0126] Wherein, the optical system 20 may further include a rear prism 203. The rear prism 203 may be located between the lens group 2012 and the image sensor 202. By arranging the rear prism 203, the function of folding the optical path can be achieved, which is beneficial to increasing the optical path length to shorten the length dimension of the imaging module 100, and is beneficial to realizing the miniaturized design of the imaging module 100. In addition, since the rear prism 203 can change the propagation direction of the light, the image sensor 202 can be obliquely arranged, thereby reducing the height dimension occupied by the image sensor 202 (i.e., the dimension in the first direction Z), and further being beneficial to reducing the shoulder height of the imaging module 100, and being beneficial to realizing the thin and light design of the imaging module 100, so as to be beneficial to the thin and light design of the electronic device 1000.

[0127] Exemplarily, the motor 10 may include a fixed base 1, a moving stage 2, a driving component 3, a self-locking component 4, and a position detection component 5. Among them, the driving component 3 is used to drive the moving stage 2 to move relative to the fixed base 1. The self-locking component 4 is used to lock the moving stage 2 on the fixed base 1 to prevent the moving stage 2 from moving relative to the fixed base 1. The self-locking component 4 is also used to unlock the moving stage 2 so that the driving component 3 can drive the moving stage 2 to move relative to the fixed base 1. The position detection component 5 is used to detect the position of the moving stage 2 relative to the fixed base 1.

[0128] Wherein, the moving stage 2 may be connected to the fixed base 1. The moving stage 2 is used to carry the optical element 2011. The driving component 3 is used to drive the moving stage 2 to drive the optical element 2011 to move relative to the fixed base 1. Wherein, the number of the light-transmitting holes 3005 on the decorative member 3003 is multiple, and the arrangement direction of the multiple light-transmitting holes 3005 is the same as the moving direction of the moving stage 2.

[0129] In this embodiment, the moving stage 2 can drive the optical element 2011 to move relative to the fixed base 1, so as to change the position of the optical element 2011, thereby changing the light-transmitting hole 3005 corresponding to the optical element 2011 and the distance between the optical element 2011 and the lens group 2012. Furthermore, the focal length of the lens 201 of the camera module 100 is changed, that is, the focal length switching of the lens 201 is achieved. For example, the switching between telephoto shooting and macro shooting is achieved.

[0130] It should be noted that Figure 2A and Figure 2B in [reference] the driving component 3 is illustrated with a magnet and a coil. It can be understood that in some other embodiments, the driving component 3 can also be a gear-rack drive, an elastic drive, etc., which are not limited herein as long as the moving stage 2 can be driven to move relative to the fixed base 1.

[0131] Among them, the load capacity of the moving stage 2 can be greater than or equal to 2000 mg. In this embodiment, the load capacity of the moving stage 2 refers to the weight that can carry the optical element 2011, that is, the moving stage 2 provided in the embodiment of the present application can drive the optical element 2011 with a weight greater than or equal to 2000 mg to move relative to the fixed base 1, realizing overweight load movement. For example, the load capacity of the moving stage 2 can be 2000 mg, or 2500 mg, or 3000 mg, etc., so that the moving stage 2 can carry a prism.

[0132] It should be noted that the load capacity of the moving stage 2 can be greater than or equal to 2000 mg, which means that the moving stage 2 has a large load capacity and does not limit the optical element 2011 carried by the moving stage 2. It can be understood that the moving stage 2 can also carry an optical element 2011 with a lighter weight, for example, an optical element 2011 with a weight less than 2000 mg.

[0133] In some other embodiments, the moving stage 2 can also carry the lens group 2012, and is used to drive the lens group 2012 to move along the second direction X to achieve zooming or focusing.

[0134] In some examples, the optical element 2011 can include a prism and a lens. The lens of the optical element 2011 can be connected to the prism and move together with the prism, so that when the optical element 2011 moves with the moving stage 2, the focal length of the lens 201 can be changed.

[0135] Among them, the lens of the optical element 2011 can be located on the object side of the prism of the optical element 2011, or can be located on the image side of the prism of the optical element 2011, or the number of lenses can be multiple, and some of them are located on the object side of the prism of the optical element 2011, and the other part is located on the image side of the prism of the optical element 2011.

[0136] It should be noted that by changing the distance between the optical element 2011 and the lens group 2012, the focal length of the lens 201 can be changed, thereby realizing the focal length switching of the lens 201. In some embodiments, within different focal length ranges, the lens group 2012 can be moved to achieve the change of the focal length within that focal length range.

[0137] It should be noted that in some other embodiments, the optical element 2011 can also be a combination of a reflector and a lens, which is not limited herein.

[0138] In some other examples, the lens 201 can further include a first lens group 2013 and a second lens group 2014. The first lens group 2013 and the second lens group 2014 can be arranged at intervals along the movement direction of the moving stage 2. The moving stage 2 is used to drive the optical element 2011 to move to a first position (please refer to Figure 2A ) to receive the light passing through the first lens group 2013. The moving stage 2 is also used to drive the optical element 2011 to move to a second position (please refer to Figure 2B ) to receive the light passing through the second lens group 2014.

[0139] In this embodiment, the moving stage 2 drives the optical element 2011 to move, so that the optical element 2011 can be combined with different lens groups 2012 at different positions to form lenses 201 with different focal lengths. For example, at the first position, the first lens group 2013, the optical element 2011, and the lens group 2012 can form a first lens with a first focal length; at the second position, the second lens group 2014, the optical element 2011, and the lens group 2012 can form a second lens with a second focal length. Among them, the first focal length is different from the second focal length. Therefore, by driving the optical element 2011 to move to different positions by the moving stage 2, the switching of different lenses 201 can be realized, such as the switching between the first lens and the second lens. By analogy, through the setting of more lens group combinations, the switching of more focal lengths can also be realized.

[0140] Among them, the first lens group 2013 and the second lens group 2014 can be installed on the decorative member 3003 or the cover plate 3001 and are arranged corresponding to the light transmission holes 3005, so that when the optical element 2011 moves to different light transmission holes 3005, the switching of the focal length can be realized. For example, the first lens group 2013 can be installed corresponding to one light transmission hole 3005, and the second lens group 2014 can be installed corresponding to another light transmission hole 3005. It should be noted that Figure 2A and Figure 2B only show the installation positions of the first lens group 2013 and the second lens group 2014, and do not limit the fixing methods of the first lens group 2013 and the second lens group 2014.

[0141] Among them, the first lens group 2013 may include one or more lenses.

[0142] Among them, the second lens group 2014 may include one or more lenses.

[0143] Among them, the first lens group 2013 and the second lens group 2014 may be the same or different.

[0144] In some embodiments, the lens group 2012 may move along the second direction X to achieve zooming or focusing of the camera module 100. In this embodiment, by moving the lens group 2012, it is beneficial to achieve continuous zooming of the camera module 100 to achieve stepless adjustment of the focal length and improve the user experience.

[0145] Exemplarily, when the optical element 2011 is located at the first position, continuous zooming within the first focal length range can be achieved by cooperating with the movement of the lens group 2012. When the optical element 2011 is located at the second position, continuous zooming within the second focal length range can be achieved by cooperating with the movement of the lens group 2012. Among them, the maximum value of the first focal length range is less than the maximum value of the second focal length range, and the first focal length range and the second focal length range partially overlap. For example, the first focal length range is from 15 mm to 22 mm, and the second focal length range is from 22 mm to 55 mm. Another example is that the first focal length range is from 10 mm to 30 mm, and the second focal length range is from 28 mm to 45 mm, etc.

[0146] It should be noted that the composition of the motor 10 in the above embodiments is only illustrative. In some other embodiments, the motor 10 may further include fewer or more components. For example, in some embodiments, the motor 10 may not include the position detection component 5. In some other embodiments, the motor 10 may further include a second driving component, and the second driving component may be connected to the lens group 2012 and the fixed base 1 to drive the lens group 2012 to move relative to the fixed base 1 along the second direction X to achieve zooming and / or focusing.

[0147] Please refer to Figure 3 and Figure 4 , Figure 3 is Figure 2A a schematic structural diagram of the motor 10 in some embodiments of the structure shown; Figure 4 is Figure 3 a partial structural diagram of the motor 10 in some embodiments shown.

[0148] In some embodiments, the motor 10 may include a rotor 10a and a stator 10b. The rotor 10a may be mounted on the stator 10b and may move relative to the stator 10b. Among them, the stator 10b may include a fixed base 1 and a circuit component 6, and the circuit component 6 may be mounted on the fixed base 1. The rotor 10a may include a moving stage 2 and a self-locking component 4. The self-locking component 4 may be fixedly mounted on the moving stage 2. The moving stage 2 may be mounted on the fixed base 1 and may move relative to the fixed base 1 to drive the self-locking component 4 to move together.

[0149] Exemplarily, the self-locking component 4 may include a driving member 41, a first telescopic member 42, and a second telescopic member 43. The driving member 41 may drive the first telescopic member 42 and the second telescopic member 43 to expand and contract simultaneously.

[0150] Please refer to Figure 5 and Figure 6 , Figure 5 is Figure 3 the schematic structural diagram of the motor 10 shown in the locked state in some embodiments after being cut along the line B-B; Figure 6 is Figure 3 the schematic structural diagram of the motor 10 shown in the unlocked state in some embodiments after being cut along the line B-B.

[0151] In some embodiments, the fixed base 1 may be provided with a first locking hole 11 and a second locking hole 12. The first locking hole 11 and the second locking hole 12 are oppositely arranged and are located on opposite sides of the driving member 41. When the motor 10 is in the locked state, the first telescopic member 42 extends into the first locking hole 11, and the second telescopic member 43 extends into the second locking hole 12. When the motor 10 is in the unlocked state, the first telescopic member 42 is located outside the first locking hole 11, and the second telescopic member 43 is located outside the second locking hole 12.

[0152] In this embodiment, by inserting the first telescopic member 42 into the first locking hole 11 and the second telescopic member 43 into the second locking hole 12, physical mechanical stable self-locking can be achieved, that is, the self-locking component 4 can lock the moving stage 2 and the fixed base 1, thereby realizing the self-locking of the motor 10, and further making the lens 201 stable, which is beneficial to improving the reliability of the lens 201 when the electronic device 1000 shakes or drops. For example, when the first telescopic member 42 extends into the first locking hole 11 and the second telescopic member 43 extends into the second locking hole 12 to lock the moving stage 2 and the fixed base 1, the stability of the lens 201 when the electronic device 1000 is shaken by the user's hand can be ensured, and the stability of the lens 201 when the electronic device 1000 drops. For example, the stability of the lens 201 when the electronic device 1000 drops from 1 meter, or 1.2 meters, or 1.4 meters, or higher.

[0153] In this embodiment, since the driving member 41 can drive the first telescopic member 42 and the second telescopic member 43 to expand and contract simultaneously, so as to realize the first telescopic member 42 moving away from each other or moving towards each other simultaneously, the two sides of the self-locking assembly 4 can be locked and unlocked simultaneously, which is beneficial to improving the smoothness of locking and unlocking.

[0154] Exemplarily, the motor 10 may further include a self-locking detection assembly 7. The self-locking detection assembly 7 may include a first magnet 71 and a detection chip 72. The first magnet 71 may be installed at the end of the first telescopic member 42 away from the driving member 41. The first magnet 71 can move with the first telescopic member 42. The detection chip 72 may be installed on the fixed base 1, and the detection chip 72 may be disposed opposite to the first magnet 71.

[0155] In this embodiment, since the first magnet 71 and the detection chip 72 are disposed opposite to each other, when the first telescopic member 42 moves relative to the first locking hole 11, the detection chip 72 can detect the position of the first magnet 71 relative to the detection chip 72, so that the relative position of the first telescopic member 42 relative to the first locking hole 11 can be accurately detected, so as to judge whether the first telescopic member 42 extends into the first locking hole 11 to complete locking, or judge whether the first telescopic member 42 disengages from the first locking hole 11 to complete unlocking, improving the accuracy of locking and unlocking of the motor 10. In addition, since the driving member 41 drives the first telescopic member 42 and the second telescopic member 43 to expand and contract simultaneously, therefore, only by detecting the first telescopic member 42 to achieve closed-loop control can the closed-loop control of the second telescopic member 43 be realized, thereby improving the stability of locking and unlocking of the moving stage 2 and the fixed base 1.

[0156] Wherein, the detection chip 72 may be installed in the first locking hole 11 or disposed adjacent to the first locking hole 11, as long as the detection chip 72 can detect the magnetic field change of the first magnet 71 to detect the position of the first telescopic member 42 relative to the first locking hole 11.

[0157] Wherein, when the motor 10 is in the locked state, the length that the first telescopic member 42 extends into the first locking hole 11 is greater than or equal to 0.5 mm to improve the locking stability between the moving stage 2 and the fixed base 1. For example, the length that the first telescopic member 42 extends into the first locking hole 11 may be, but is not limited to, 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, or other values greater than 0.5 mm.

[0158] Exemplarily, the motor 10 may further include a stop member 8. When the motor 10 is in the locked state, the stop member 8 blocks the first telescopic member 42 from continuing to move towards the first locking hole 11.

[0159] In this embodiment, by providing the stop member 8, the first telescopic member 42 can be limited in the locked state, thereby preventing the first telescopic member 42 from moving further toward the first locking hole 11 under external forces (such as dropping, impact, etc.), so as to prevent damage to the first telescopic member 42, the second telescopic member 43 and the driving member 41, and also avoid collision between the first telescopic member 42 and the detection chip 72, which may damage the detection chip 72. With such a design, the problem that the output torque of the driving member 41 is small due to the limited installation space of the motor 10, resulting in the inability to achieve self-locking between the driving member 41 and the first telescopic member 42 and the second telescopic member 43, is overcome. Also overcome is the problem that due to power consumption limitations, the detection chip 72 cannot be continuously powered on to perform closed-loop detection of the position of the first screw 421. Therefore, the provision of the stop member 8 can not only protect the components in the motor 10 and improve the overall anti-external impact ability of the motor 10, but also reduce power consumption through physical stopping, thereby saving power.

[0160] Exemplarily, the first telescopic member 42 may include a first screw 421 and a first nut 422. The first nut 422 is fixedly installed on the moving stage 2. The first screw 421 passes through the first nut 422 and is threadedly connected to the first nut 422. The driving member 41 is used to drive the first screw 421 to rotate relative to the first nut 422, so as to drive the first screw 421 to extend or retract relative to the moving stage 2. When the motor 10 is in the locked state, the first screw 421 extends into the first locking hole 11, and the stop member 8 blocks the first screw 421 from further extending relative to the first moving stage 2.

[0161] In this embodiment, the driving member 41 can drive the first screw 421 to rotate relative to the first nut 422, so that the first screw 421 can move along the third direction Y relative to the first nut 422 to achieve extension and retraction. Since the first screw 421 and the first nut 422 in the first telescopic member adopt a nut connection, the first telescopic member 42 can stably stay at any position after the driving member 41 stops driving, that is, the power-off locking of the self-locking assembly 4 is realized, which is beneficial to energy saving. Since the power-off locking is achieved without the cooperation of external forces, when the driving member 41 is powered on, it does not need to overcome external forces other than the frictional force between the first screw 421 and the first nut 422, reducing the driving force required to drive the first screw 421 to move relative to the first nut 422, which is beneficial to energy saving.

[0162] In addition, since the driving member 41 drives the first screw 421 to rotate, and the cooperation between the first screw 421 and the first nut 422 can convert the rotation into linear motion, when the self-locking assembly 4 is in the power-off locked state, a corresponding rotational force needs to be applied to the first screw 421 to break the locking of the self-locking assembly 4, which makes it difficult to break the locked state of the self-locking assembly 4 and improves the stability of the self-locking assembly 4 in the power-off locked state.

[0163] Wherein, the first screw rod 421 may include a first part 421a and a second part 421b. The first part 421a of the first screw rod 421 is closer to the driving member 41 than the second part 421b of the first screw rod 421, and a first external thread 4211 is provided on the first part 421a of the first screw rod 421. When the motor 10 is in a locked state, a part of the second part 421b of the first screw rod 421 extends into the first locking hole 11.

[0164] It should be noted that Figure 5 and Figure 6 in the figure, the first part 421a and the second part 421b of the first screw rod 421 are schematically divided by a dotted line. It can be understood that in some other embodiments, the division between the first part 421a and the second part 421b of the first screw rod 421 may also be located elsewhere.

[0165] In this embodiment, the first screw rod 421 realizes threaded connection with the first nut 422 through the first part 421a and realizes cooperation with the first locking hole 11 through the second part 421b.

[0166] In some examples, please continue to refer to Figure 5 and Figure 6 , the stopper 8 can be installed on the moving stage 2. The stopper 8 is located on the side of the first nut 422 away from the driving member 41, and the stopper 8 may have a first through hole 81. The maximum outer diameter of the second part 421b of the first screw rod 421 (refer to D2 in Figure 5 ) can be smaller than the maximum outer diameter of the first part 421a of the first screw rod 421 (refer to D1 in Figure 5 ), and the inner diameter of the first through hole 81 (refer to D3 in Figure 5 ) is greater than the maximum outer diameter of the second part 421b of the first screw rod 421 and smaller than the maximum outer diameter of the first part 421a of the first screw rod 421, that is: D2 < D3 < D1.

[0167] In this embodiment, through the setting of the stop member 8, the second part 421b of the first screw 421 can pass through the first through hole 81 of the stop member 8, so as to realize the extension and retraction of the first screw 421 relative to the first locking hole 11, and thus realize the locking and unlocking of the motor 10. In addition, the stop member 8 can form a limit on the first part 421a of the first screw 421 at the first through hole 81 to prevent the first part 421a of the first screw 421 from passing through the first through hole 81. With such a setting, when the second part 421b of the first screw 421 extends into the first locking hole 11 and the motor 10 is in a locked state, a stable stop limit can be provided for the motor 10 to prevent the first screw 421 from further moving towards the first locking hole 11, so as to protect components such as the driving member 41 and the detection chip 72.

[0168] Wherein, when the motor 10 is in an unlocked state, at least a part of the second part 421b of the first screw 421 is located within the first through hole 81 to avoid excessive retraction of the first screw 421, so as to avoid the first screw 421 being blocked by the stop member 8 after retracting due to the deviation existing in the assembly of the first nut 422, the first screw 421 and the stop member 8, and further avoid the first screw 421 from being stuck.

[0169] In some other examples, please refer to Figure 7 , Figure 7 is Figure 3 the schematic structural diagram of the motor 10 shown in a locked state after being cut along line B-B in some other embodiments. The first nut 422 has a first threaded hole 4221, and the first screw 421 is disposed through the first threaded hole 4221. The stop member 8 is disposed at the end of the first screw 421 close to the driving member 41, and the outer diameter of the stop member 8 (please refer to D4 in Figure 7 ) is larger than the inner diameter of the first threaded hole 4221 (please refer to D5 in Figure 7 ). When the motor 10 is in a locked state, the stop member 8 abuts against the first nut 422.

[0170] In this embodiment, by disposing the stop member 8 at the end of the first screw 421, a limit can be formed by using the dimensional relationship between the stop member 8 and the first threaded hole 4221 of the first nut 422, so as to prevent the first screw 421 from extending too far relative to the first nut 422. When the second part 421b of the first screw 421 extends into the first locking hole 11 and the motor 10 is in a locked state, a stable stop limit can be provided for the motor 10 to prevent the first screw 421 from further moving towards the first locking hole 11, so as to protect components such as the driving member 41 and the detection chip 72.

[0171] Among them, the stopper 8 and the first screw 421 can be an integral structure to improve the overall structural stability of the first screw 421 and the stopper 8, which is beneficial to improving the strength of the limit formed between the stopper 8 and the first nut 422, and further beneficial to improving the reliability of the motor 10 in the locked state.

[0172] Please continue to refer to Figure 5 , in some embodiments, the motor 10 may further include a magnetic attraction assembly 9, and the magnetic attraction assembly 9 may include a second magnet 91 and a magnetic attraction member 92. The second magnet 91 may be installed at the end of the second telescopic member 43 away from the driving member 41, the second magnet 91 can move with the second telescopic member 43, and the magnetic attraction member 92 may be installed on the base, and the magnetic attraction member 92 is disposed opposite to the second magnet 91.

[0173] In this embodiment, through the design of the magnetic attraction assembly 9, a magnetic attraction force can be generated between the magnetic attraction member 92 and the second magnet 91. In this way, when the motor 10 is in the locked state, the magnetic attraction member 92 can magnetically attract the second magnet 91 to magnetically lock and stop the second telescopic member 43 and the fixed base 1, which can prevent the second telescopic member 43 from retracting due to external forces (such as dropping, impact, etc.), and can improve the locking stability between the moving stage 2 and the fixed base 1.

[0214] In this embodiment, through the arrangement of the first transmission shaft 44 and the second transmission shaft 45, the function of connecting the first end 4121 of the output shaft 412 with the first telescopic member 42 and connecting the second end 4122 of the output shaft 412 with the second telescopic member 43 can be achieved. Since the output shaft 412 is the self-structure of the driving member 41, the output of the driving member 41 may be limited by the shape of the output shaft 412. By designing the shapes of the first transmission shaft 44 and the second transmission shaft 45, the transmission connection form of the driving member 41 can be changed, so that the driving member 41 can better match the first telescopic member 42 and the second telescopic member 43.

[0215] In this embodiment, since the driving member 41 can realize the synchronous movement of the first telescopic member 42 and the second telescopic member 43 on both sides through the first end 4121 and the second end 4122 of the output shaft 412, the bilateral drive of the driving member 41 is realized, so as to simultaneously drive the first transmission shaft 44 and the second transmission shaft 45 located on both sides of the driving member 41 to rotate, thereby respectively driving the first telescopic member 42 and the second telescopic member 43 to move, so as to realize the simultaneous locking and unlocking on both sides of the self-locking assembly 4, which is beneficial to improving the smoothness of locking and unlocking.

[0216] Exemplarily, the first telescopic member 42 may include a first screw 421 and a first nut 422. The first screw 421 may be connected to the first transmission shaft 44. The first screw 421 may pass through the first nut 422 and be threadedly connected to the first nut 422.

[0217] In this embodiment, the driving member 41 can rotate through the output shaft 412 to drive the first transmission shaft 44 to rotate. The rotation of the first transmission shaft 44 can drive the first screw 421 to rotate relative to the first nut 422. Driven by the first transmission shaft 44, the first screw 421 can move relative to the first nut 422 along the third direction Y to achieve extension and retraction. Since a nut connection is adopted between the first screw 421 and the first nut 422 in the first telescopic member 42, the first telescopic member 42 can stably stay at any position after the driving member 41 stops driving, that is, the power-off locking of the self-locking assembly 4 is realized, which is beneficial to energy saving. Since no external force is required to achieve power-off locking, when the driving member 41 is powered on, no external force other than the friction force between the first screw 421 and the first nut 422 needs to be overcome, reducing the driving force required to drive the first screw 421 to move relative to the first nut 422, which is beneficial to energy saving.

[0218] In addition, since the driving member 41 drives the first screw 421 through rotational output, and the cooperation between the first screw 421 and the first nut 422 can convert rotation into linear motion. Therefore, when the self-locking assembly 4 is in the power-off locking state, a corresponding rotational force needs to be applied to the first screw 421 to break the locking of the self-locking assembly 4, which makes it difficult to break the locking state of the self-locking assembly 4 and improves the stability of the self-locking assembly 4 during power-off locking.

[0219] Exemplarily, the second telescopic member 43 may include a second screw 431 and a second nut 432. The second screw 431 may be connected to the second transmission shaft 45, and the second nut 432 may be installed on the moving stage 2. The second screw 431 may pass through the second nut 432 and be threadedly connected to the second nut 432.

[0220] In this embodiment, the driving member 41 can rotate through the output shaft 412 to drive the second transmission shaft 45 to rotate. The rotation of the second transmission shaft 45 can drive the second screw 431 to rotate relative to the second nut 432. Driven by the second transmission shaft 45, the second screw 431 can move relative to the second nut 432 along the third direction Y to achieve extension and retraction. Since a nut connection is adopted between the second screw 431 and the second nut 432 in the second telescopic member 43, the second telescopic member 43 can stably stay at any position after the driving member 41 stops driving, that is, the power-off locking of the self-locking assembly 4 is realized, which is beneficial to energy saving. Since no external force is required to achieve power-off locking, when the driving member 41 is powered on, no external force other than the friction force between the second screw 431 and the second nut 432 needs to be overcome, reducing the driving force required to drive the second screw 431 to move relative to the second nut 432, which is beneficial to energy saving.

[0221] In addition, since the driving member 41 drives the second screw 431 through rotational output, and the cooperation between the second screw 431 and the second nut 432 can convert rotation into linear motion. Therefore, when the self-locking assembly 4 is in power-off locking, a corresponding rotational force needs to be applied to the screw to break the locking of the self-locking assembly 4, which makes it difficult to break the locking state of the self-locking assembly 4 and improves the stability of the self-locking assembly 4 during power-off locking.

[0222] Exemplarily, the driving member 41 can be a stepper motor, which is beneficial to the rotation control of the output shaft 412 of the driving member 41 to achieve stable rotation of the output shaft 412, and is also beneficial to making the feed amounts of the first screws 421 and the second screw 431 on both sides consistent.

[0223] In some embodiments, the first transmission shaft 44 and the output shaft 412 can be an integral structure, and / or the second transmission shaft 45 and the output shaft 412 can be an integral structure, so as to shorten the transmission chain of the self-locking assembly 4, which is beneficial to simplifying the transmission relationship, reducing the transmission error, and thus beneficial to making the movement feed amounts on both sides of the driving member 41 tend to be consistent.

[0225] In some embodiments, the body 411 can include a housing 4111, a first bearing 4112, a second bearing 4113, a first end plate 4114, a second end plate 4115 and a reinforcing plate 4116.

Among them, the first end plate 4114 can be sleeved on the first bearing 4112, and the second end plate 4115 can be sleeved on the second bearing 4113. The reinforcing plate 4116 can be connected between the first end plate 4114 and the second end plate 4115.

[0226] Exemplarily, the reinforcing plate 4116 can be provided with a fixing hole 4117, and the fixing hole 4117 is located between the first end plate 4114 and the second end plate 4115.

[0227] Exemplarily, the output shaft 412 can pass through the first bearing 4112, the housing 4111 and the second bearing 4113.

[0228] In some embodiments, the driving member 41 may further include a movement 413 and pins 414. The movement 413 is disposed inside the housing 4111 and is used to drive the output shaft 412 to rotate. The pins 414 are exposed from the housing 4111 and are electrically connected to the movement 413 for connecting to an external circuit to supply power to the movement 413.

[0229] Please refer to the combination part Figures 20 to 21B , Fig. 20 is Fig.17A a schematic structural view of the first transmission shaft 44 and the second transmission shaft 45 in the self-locking assembly 4 in some embodiments; Fig.21A is Fig. 20 a schematic structural view of the first transmission shaft 44 and the second transmission shaft 45 installed on the Fig.18A driving member 41 shown in some embodiments; Fig. 21B is Fig.21A a schematic structural view of the structure shown in some embodiments after being cut along the line G-G. Among them, Fig. 20 (a) in is the first transmission shaft 44, Fig. 20 (b) in is the second transmission shaft 45.

[0230] In some embodiments, the first transmission shaft 44 may include a first part 44a and a second part 44b. The first part 44a of the first transmission shaft 44 is fixedly connected to the first end 4121 of the output shaft 412. It should be noted that, Fig. 20 (a) in schematically divides the first part 44a and the second part 44b of the first transmission shaft 44. It can be understood that in some other embodiments, the division of the first part 44a and the second part 44b of the first transmission shaft 44 may also be located elsewhere.

[0231] Exemplarily, a first mounting groove 441 is provided on the end face of the first part 44a of the first transmission shaft 44, and the first end 4121 of the output shaft 412 is installed in the first mounting groove 441.

[0232] In this embodiment, through the design of the first mounting groove 441, the stability of the connection between the first end 4121 of the output shaft 412 and the first transmission shaft 44 can be improved, which is beneficial to the stability of the transmission between the output shaft 412 and the first transmission shaft 44.

[0233] Among them, the opposite sides of the first end 4121 of the output shaft 412 are fixedly connected to the side walls of the first mounting groove 441.

[0234] In this embodiment, by fixedly connecting the opposite sides of the first end 4121 of the output shaft 412 to the side walls of the first mounting groove 441, it is beneficial to improve the balance of the connection between the first end 4121 of the output shaft 412 and the first transmission shaft 44, making the assembly connection between the first end 4121 of the output shaft 412 and the first transmission shaft 44 more stable and capable of avoiding the problem of the first transmission shaft 44 tilting during assembly.

[0235] Among them, the opposite sides of the first end 4121 of the output shaft 412 can be welded to the side walls of the first mounting groove 441. For example, laser welding can be used between the first end 4121 of the output shaft 412 and the side walls of the first mounting groove 441. After the first end 4121 of the output shaft 412 extends into the first mounting groove 441, the first part 44a of the first transmission shaft 44 can be penetrated by laser, and the first welding material 46 can be used to achieve the welding between the first end 4121 of the output shaft 412 and the first part 44a of the first transmission shaft 44.

[0236] Among them, the end face of the first end 4121 of the output shaft 412 can abut against the bottom wall of the first mounting groove 441 to increase the overlapping area between the first end 4121 of the output shaft 412 and the first mounting groove 441, thereby improving the stability of the assembly between the first end 4121 of the output shaft 412 and the first mounting groove 441.

[0237] It should be noted that laser welding will leave a first welding hole 443 on the first transmission shaft 44. The first welding hole 443 communicates with the first mounting groove 441. The first welding material 46 will connect the first end 4121 of the output shaft 412 to the side wall of the first mounting groove 441, and part of the first welding material 46 will also be connected to the hole wall of the first welding hole 443. Among them, the number of the first welding holes 443 can be two or more, including at least two first welding holes 443 located on both sides of the first transmission shaft 44.

[0238] In some other embodiments, other connection methods can also be used between the first end 4121 of the output shaft 412 and the side wall of the first mounting groove 441, such as bonding, clamping, etc., which will not be limited one by one here.

[0239] In some embodiments, the second transmission shaft 45 can include a first part 45a and a second part 45b. The first part 45a of the second transmission shaft 45 is fixedly connected to the second end 4122 of the output shaft 412. It should be noted that Fig. 20 In (b), the first part 45a and the second part 45b of the second transmission shaft 45 are schematically divided by a dotted line. It can be understood that in some other embodiments, the division of the first part 45a and the second part 45b of the second transmission shaft 45 can also be located elsewhere.

[0240] Exemplarily, a second mounting groove 451 is provided on the end face of the first part 45a of the second transmission shaft 45, and the second end 4122 of the output shaft 412 is mounted in the second mounting groove 451.

[0241] In this embodiment, through the design of the second mounting groove 451, the stability of the connection between the second end 4122 of the output shaft 412 and the second transmission shaft 45 can be improved, which is beneficial to the stability of the transmission between the output shaft 412 and the second transmission shaft 45.

[0242] Wherein, the opposite sides of the second end 4122 of the output shaft 412 are fixedly connected to the side walls of the second mounting groove 451.

[0243] In this embodiment, by setting the opposite sides of the second end 4122 of the output shaft 412 to be fixedly connected to the side walls of the second mounting groove 451, it is beneficial to improve the balance of the connection between the second end 4122 of the output shaft 412 and the second transmission shaft 45, making the assembly connection between the second end 4122 of the output shaft 412 and the second transmission shaft 45 more stable, and avoiding the problem of the second transmission shaft 45 tilting during assembly.

[0244] Wherein, the opposite sides of the second end 4122 of the output shaft 412 can be welded to the side walls of the second mounting groove 451. For example, laser welding can be used between the second end 4122 of the output shaft 412 and the side walls of the second mounting groove 451. After the second end 4122 of the output shaft 412 is inserted into the second mounting groove 451, the first part 45a of the second transmission shaft 45 can be penetrated by laser, and the second welding material 47 can be used to realize the welding between the second end 4122 of the output shaft 412 and the first part 45a of the second transmission shaft 45.

[0245] Wherein, the end face of the second end 4122 of the output shaft 412 can be abutted against the bottom wall of the second mounting groove 451 to increase the overlapping area between the second end 4122 of the output shaft 412 and the second mounting groove 451, thereby improving the stability of the assembly between the second end 4122 of the output shaft 412 and the second mounting groove 451.

[0246] It should be noted that laser welding will leave a second welding hole 453 on the second transmission shaft 45. The second welding hole 453 communicates with the second mounting groove 451. The second welding material 47 will connect the second end 4122 of the output shaft 412 and the side walls of the second mounting groove 451, and part of the second welding material 47 will also be connected to the hole wall of the second welding hole 453. Among them, the number of the second welding holes 453 can be two or more, and at least two second welding holes 453 located on both sides of the second transmission shaft 45 are included.

[0247] In some other embodiments, other connection methods may also be adopted between the second end 4122 of the output shaft 412 and the side wall of the second mounting groove 451, such as bonding, snap connection, etc., which are not limited one by one herein.

[0248] Please refer to Figures 22 to 23B , Fig. 22 which Fig.17A is a schematic structural diagram of the first screw 421 and the second screw 431 in the self-locking assembly 4 shown in some embodiments; Fig.23A which Fig. 22 is a schematic structural diagram of the first screw 421 and the second screw 431 installed in the structure shown in some embodiments; Fig.21A is a schematic structural diagram of the structure shown in some embodiments after being cut along the line H-H shown in Fig. 23B which Fig.23A . Among them, Fig. 22 (a) in Fig. 22 is the first screw 421,

[0249] (b) in

[0250] In some embodiments, the first screw 421 may include a first part 421a and a second part 421b. A first transmission groove 4212 may be provided on the end face of the first part 421a of the first screw 421 away from the second part 421b of the first screw 421. At least part of the second part 44b of the first transmission shaft 44 may be located in the first transmission groove 4212. The second part 44b of the first transmission shaft 44 abuts against the side wall of the first transmission groove 4212 under the drive of the output shaft 412 to drive the first screw 421 to rotate.

[0251] Exemplarily, the second part 44b of the first transmission shaft 44 may have a first transmission surface 442. The first transmission surface 442 can abut against the side wall of the first transmission groove 4212 under the rotation of the first transmission shaft 44 to drive the first screw 421 to rotate. A first assembly gap may be provided between the first transmission surface 442 and the side wall of the first transmission groove 4212 to achieve assembly tolerance, thereby avoiding jamming during the process of the transmission shaft driving the first screw 421 to rotate.

[0252] Among them, the self-locking component 4 may further include an elastic member (not shown in the figure). The elastic member can be filled in the first assembly gap, so that the first transmission surface 442 can squeeze the elastic member under the rotation of the first transmission shaft 44. The elastic member can deform, so that the first transmission surface 442 can move relative to the first transmission shaft 44 by squeezing the elastic member, thereby playing a tolerance role, which can be regarded as providing a transmission margin space between the first transmission shaft 44 and the first screw 421, thus avoiding jamming during the process of the first transmission shaft 44 driving the first screw 421 to rotate.

[0253] Among them, the size d0 of the first assembly gap satisfies: 0 < d0 ≤ 0.2 mm. For example, the value of d0 can be but is not limited to 0, or 0.02 mm, or 0.04 mm, or 0.06 mm, or 0.08 mm, or 0.1 mm, or 0.12 mm, or 0.14 mm, or 0.16 mm, or 0.18 mm, or 0.2 mm, or other values between 0 and 0.2 mm.

[0254] In this embodiment, the size d0 of the first assembly gap satisfies the above relationship, which is conducive to forming assembly tolerance, avoiding jamming during the process of the first transmission shaft 44 driving the first screw 421 to rotate, and can avoid excessive clearance, resulting in hysteresis in the transmission between the first transmission shaft 44 and the first screw 421.

[0255] Among them, the second part 44b of the first transmission shaft 44 may have a plurality of first transmission surfaces 442. The shape of the second part 44b of the first transmission shaft 44 and the first transmission groove 4212 of the first screw 421 may be the same. Each first transmission surface 442 is arranged corresponding to a side wall of the first transmission groove 4212, and there is a first assembly gap between the side walls of the first transmission groove 4212 corresponding to each first transmission surface 442.

[0256] For example, the cross-sectional shape of the second part 44b of the first transmission shaft 44 in the plane perpendicular to the third direction Y may be but is not limited to a straight shape, a cross shape, a regular polygon, etc. Correspondingly, the first transmission groove 4212 is adapted to the shape of the second part 44b of the first transmission shaft 44.

[0257] Exemplarily, the second part 44b of the first transmission shaft 44 may be elastic. The second part 44b of the first transmission shaft 44 may be located in the first transmission groove 4212 and abut against the side wall of the first transmission groove 4212.

[0258] In this embodiment, since the second part 44b of the first transmission shaft 44 is elastic, there is no need to provide a gap between the second part 44b of the first transmission shaft 44 and the side wall of the first transmission groove 4212. The tolerance function can be achieved through the elastic deformation of the second part 44b of the first transmission shaft 44, avoiding jamming during the process of the first transmission shaft 44 driving the first screw 421 to rotate.

[0259] In some embodiments, a first accommodation groove 4213 may be provided on the end face of the second part 421b of the first screw 421.

[0260] In some embodiments, the second screw 431 may include a first part 431a and a second part 431b. A second transmission groove 4311 may be provided on the end face of the first part 431a of the second screw 431 away from the second part 431b of the second screw 431. At least a part of the second part 45b of the second transmission shaft 45 may be located in the second transmission groove 4311. The second part 45b of the second transmission shaft 45 abuts against the side wall of the second transmission groove 4311 under the drive of the output shaft 412 to drive the second screw 431 to rotate.

[0261] In this embodiment, through the design of the second transmission groove 4311, a transmission connection can be formed between the second transmission shaft 45 and the second screw 431, thereby forming a transmission chain. The second end 4122 of the output shaft 412 can drive the second screw 431 to rotate by driving the second transmission shaft 45 to rotate.

[0262] Exemplarily, the second part 45b of the second transmission shaft 45 may have a second transmission surface 452. The second transmission surface 452 can abut against the side wall of the second transmission groove 4311 under the rotation of the second transmission shaft 45 to drive the second screw 431 to rotate. A second assembly gap may be provided between the second transmission surface 452 and the side wall of the second transmission groove 4311 to achieve assembly tolerance, thereby avoiding jamming during the process of the transmission shaft driving the second screw 431 to rotate.

[0263] Wherein, the self-locking assembly 4 may further include an elastic member (not shown in the figure). The elastic member may be filled in the second assembly gap, so that the second transmission surface 452 can squeeze the elastic member under the rotation of the second transmission shaft 45, and the elastic member can deform, so that the second transmission surface 452 can move relative to the second transmission shaft 45 by squeezing the elastic member, thereby playing a tolerance role, which can be regarded as providing a transmission margin space between the second transmission shaft 45 and the second screw 431, thereby avoiding jamming during the process of the second transmission shaft 45 driving the second screw 431 to rotate.

[0264] Wherein, the size of the second assembly gap may be the same as the size of the first assembly gap.

[0265] In this embodiment, the size of the second assembly gap is the same as that of the first assembly gap, which is conducive to forming an assembly tolerance, avoiding jamming during the process of the second transmission shaft 45 driving the second screw 431 to rotate, and can also avoid excessive gaps, resulting in hysteresis in the transmission between the second transmission shaft 45 and the second screw 431.

[0266] Among them, the second part 45b of the second transmission shaft 45 may have a plurality of second transmission surfaces 452. The shape of the second part 45b of the second transmission shaft 45 and the second transmission groove 4311 of the second screw 431 may be the same. Each second transmission surface 452 is disposed corresponding to a side wall of the second transmission groove 4311, and there is a second assembly gap between the side walls of the second transmission groove 4311 corresponding to each second transmission surface 452.

[0267] For example, the cross-sectional shape of the second part 45b of the second transmission shaft 45 in a plane perpendicular to the third direction Y may be, but is not limited to, a straight shape, a cross shape, a regular polygon, etc. Correspondingly, the second transmission groove 4311 is adapted to the shape of the second part 45b of the second transmission shaft 45.

[0268] Exemplarily, the second part 45b of the second transmission shaft 45 may be elastic. The second part 45b of the second transmission shaft 45 may be located in the second transmission groove 4311 and abut against the side wall of the second transmission groove 4311.

[0269] In this embodiment, since the second part 45b of the second transmission shaft 45 is elastic, there is no need to provide a gap between the second part 45b of the second transmission shaft 45 and the side wall of the second transmission groove 4311. The tolerance function can be realized through the elastic deformation of the second part 45b of the second transmission shaft 45, avoiding jamming during the process of the second transmission shaft 45 driving the second screw 431 to rotate.

[0270] In some embodiments, the number of the first transmission surfaces 442 of the first transmission shaft 44 may be the same as the number of the second transmission surfaces 452 of the second transmission shaft 45, and the first transmission surfaces 442 and the second transmission surfaces 452 are arranged in one-to-one correspondence, and the first transmission surfaces 442 and the corresponding second transmission surfaces 452 are arranged in parallel, which is conducive to ensuring that the transmission paces on both sides of the driving member 41 are consistent, so as to ensure that the feed amounts of the first screw 421 and the second screw 431 tend to be the same.

[0271] In some embodiments, a second receiving groove 4313 may be provided on the end surface of the second part 431b of the second screw 431.

[0272] Please continue to refer to Fig. 22 and Fig.23A, in some embodiments, a first external thread 4211 is provided on a first portion 421a of the first screw 421, and a second external thread 4312 is provided on a first portion 431a of the second screw 431.

[0273] Exemplarily, the thread directions of the first external thread 4211 and the second external thread 4312 may be opposite, so that the driving member 41 can drive the first screw 421 and the second screw 431 on both sides to extend or retract simultaneously through the output shaft 412.

[0274] Exemplarily, the pitches of the first external thread 4211 and the second external thread 4312 may be the same, so that when the driving member 41 drives the first screw 421 and the second screw 431 to rotate, the feed amounts of the first screw 421 and the second screw 431 are the same.

[0275] Exemplarily, the first external thread 4211 may have a first thread starting point 4214. In a plane perpendicular to the axis L1 of the first screw 421 and passing through the first thread starting point 4214, a first connection line M1 is formed by connecting the first thread starting point 4214 and the center O1 of the first screw 421, and a first included angle α1 is formed between the first connection line M1 and the axis L1 of the first screw 421. The second external thread 4312 may have a second thread starting point 4314. In a plane perpendicular to the axis L2 of the second screw 431 and passing through the second thread starting point 4314, a second connection line M2 is formed by connecting the second thread starting point 4314 and the center O2 of the second screw 431, and a second included angle α2 is formed between the second connection line M2 and the axis L2 of the second screw 431. The difference between the first included angle α1 and the second included angle α2 is less than or equal to 2°. For example, the value of |α1 - α2| may be but is not limited to 2°, or 1.7°, or 1.4°, or 1.1°, or 0.8°, or 0.5°, or 0.4°, or 0.3°, or 0.2°, or 0.1°, or 0, or other values less than 2°.

[0276] In this embodiment, by designing |α1 - α2| to be less than or equal to 2°, it is beneficial to ensure that under the drive of the driving member 41, the feed amounts of the first screw 421 and the second screw 431 on both sides of the driving member 41 tend to be consistent.

[0277] It should be noted that the above-provided method for the deviation angle between the first thread starting point 4214 of the first screw 421 and the second thread starting point 4314 of the second screw 431 is only for illustration. It can be understood that other included angles between other connection lines can also be used for comparison, as long as the reference objects of the first thread starting point 4214 and the second thread starting point 4314 are correspondingly consistent. In the case where the reference objects of the two are consistent, the deviation angle should satisfy less than or equal to 2°.

[0278] Please refer to FIG. 24A to FIG. 25A , Fig.24A is Fig.17A Schematic structural diagram of the first nut 422 and the second nut 432 in the self-locking assembly 4 shown in some embodiments; Fig. 24B is Fig.24A Schematic cross-sectional view of the first nut 422 and the second nut 432 shown in some embodiments; Fig.25A is Fig.17A Schematic structural diagram of the self-locking assembly 4 shown after being cut along line J-J in some embodiments. Among them, Fig.24A (a) in is the first nut 422, Fig.24A (b) in is the second nut 432. Fig. 24B (a) in is the first nut 422, Fig. 24B (b) in is the second nut 432.

[0279] In some embodiments, the first nut 422 may have a first threaded hole 4221, a first internal thread 4222 is provided in the first threaded hole 4221, the first screw 421 has a first external thread 4211, the first screw 421 passes through the first threaded hole 4221, and the first external thread 4211 is threadedly connected to the first internal thread 4222. The second nut 432 may have a second threaded hole 4321, a second internal thread 4322 is provided in the second threaded hole 4321, the second screw 431 has a second external thread 4312, the second screw 431 passes through the second threaded hole 4321, and the second external thread 4312 is threadedly connected to the second internal thread 4322. The thread direction of the first internal thread 4222 is opposite to the thread direction of the second internal thread 4322.

[0280] In this embodiment, through the design of the first nut 422, the first screw 421 can rotate relative to the first nut 422 and move along the third direction Y relative to the first nut 422. Through the design of the second nut 432, the second screw 431 can rotate relative to the second nut 432 and move along the third direction Y relative to the second nut 432. Since the thread direction of the first nut 422 is opposite to the thread direction of the second nut 432, the first screw 421 and the second screw 431 can move in opposite directions along the third direction Y at the same time to achieve simultaneous expansion and contraction.

[0281] Exemplarily, the pitch of the first internal thread 4222 and the pitch of the second internal thread 4322 may be the same, so that when the driving member 41 drives the first screw 421 and the second screw 431 to rotate, the moving stroke of the first screw 421 relative to the first nut 422 and the moving stroke of the second screw 431 relative to the second nut 432 are the same, that is, the feed amounts of the first screw 421 and the second screw 431 are the same.

[0282] Exemplarily, the first internal thread 4222 has a third thread starting point 4223. In a plane perpendicular to the axis L3 of the first nut 422 and passing through the third thread starting point 4223, a third connection line M3 is formed by connecting the third thread starting point 4223 with the center O3 of the first nut 422. There is a third included angle α3 between the third connection line M3 and the axis L3 of the first nut 422. The second internal thread 4322 has a fourth thread starting point 4323. In a plane perpendicular to the axis L4 of the second nut 432 and passing through the fourth thread starting point 4323, a fourth connection line M4 is formed by connecting the fourth thread starting point 4323 with the center O4 of the second nut 432. There is a fourth included angle α4 between the fourth connection line M4 and the axis L4 of the second nut 432. The difference between the third included angle α3 and the fourth included angle α4 is less than or equal to 2°. For example, the value of |α3 - α4| can be, but is not limited to, 2°, or 1.7°, or 1.4°, or 1.1°, or 0.8°, or 0.5°, or 0.4°, or 0.3°, or 0.2°, or 0.1°, or 0, or other values less than 2°.

[0283] In this embodiment, by designing |α3 - α4| to be less than or equal to 2°, it is beneficial to ensure that under the drive of the driving member 41, the feed amounts of the first screw rod 421 and the second screw rod 431 on both sides of the driving member 41 tend to be consistent.

[0284] It should be noted that the above-provided method of the deviation angle between the third thread starting point 4223 of the first nut 422 and the fourth thread starting point 4323 of the second nut 432 is only for illustration. Understandably, other included angles between connection lines can also be used for comparison, as long as the reference objects of the third thread starting point 4223 and the fourth thread starting point 4323 are correspondingly consistent. When the reference objects of the two are consistent, the deviation angle should satisfy being less than or equal to 2°.

[0285] Please refer to Figure 6 、 Fig. 20 and Fig.25B , Fig.25B is Fig.25A the schematic structural diagram of the retraction of the first screw rod 421 and the second screw rod 431 in the self-locking assembly 4 shown.

[0286] In some embodiments, when the motor 10 is in the unlocked state, the first transmission shaft 44 abuts against the first screw rod 421, and at least a part of the first screw rod 421 is located in the first through hole 81 of the stopper 8.

[0287] In this embodiment, through the design of the first transmission shaft 44, a limit for the retraction of the first screw 421 is formed, which can prevent the first screw 421 from retracting too much, thereby avoiding the situation that the first screw 421 is blocked by the stop member 8 after retraction due to the deviation existing during the assembly of the first nut 422, the first screw 421, and the stop member 8, and further avoiding the jamming of the first screw 421.

[0288] In some examples, when the motor 10 is in the unlocked state, the second part 44b of the first transmission shaft 44 is in contact with the bottom wall of the first transmission groove 4212. At this time, the end face of the second part 44b of the first transmission shaft 44 forms a limit for the retraction of the first screw 421, which can prevent the first screw 421 from retracting excessively.

[0289] In other examples, the outer diameter of the first part 44a of the first transmission shaft 44 is greater than the outer diameter of the second part 44b of the first transmission shaft 44. The first part 44a of the first transmission shaft 44 forms a first limiting surface 444 at the connection with the second part 44b of the first transmission shaft 44, and the first limiting surface 444 is exposed from the second part 44b of the first transmission shaft 44. When the motor 10 is in the unlocked state, the first limiting surface 444 abuts against the end face of the first part 421a of the first screw 421 that is away from the second part 421b of the first screw 421. At this time, the first limiting surface 444 forms a limit for the retraction of the first screw 421, which can prevent the first screw 421 from retracting excessively.

[0290] It should be noted that since the first screw 421 and the second screw 431 are simultaneously driven by the output shaft 412, therefore, a limiting structure for preventing the second screw 431 from retracting excessively may not be provided between the second screw 431 and the second transmission shaft 45. It can be understood that the structural design between the second screw 431 and the second transmission shaft 45 can adopt the same limiting structure design as that between the first screw 421 and the first transmission shaft 44.

Since the second limiting rib 218 has a V-shaped structure or a U-shaped structure, the positioning of the second bearing 4113 can be achieved. Through the design of the first limiting rib 217 and the second limiting rib 218, the overall positioning and installation of the driving member 41 can be achieved, and the problem of inclination during the assembly of the driving member 41 can be solved, thereby improving the stability of the self-locking assembly 4 during operation.

[0296] Exemplarily, a part of the first end plate 4114 can be located in the first limiting hole 214, and a part of the second end plate 4115 can be located in the second limiting hole 215.

[0297] In this embodiment, through the clamping of the first end plate 4114 by the first limiting hole 214 and the clamping of the second end plate 4115 by the second limiting hole 215, the stability of the installation between the driving member 41 and the moving stage 2 can be further improved, thereby further strengthening the installation of the driving member 41.
