Description

Motor device, camera module and electronic device

[0001] The present application claims priority to the Chinese patent application No. 202411340336.2, filed on September 24, 2024, and entitled "Motor device, camera module and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of camera technology, in particular to a motor device, a camera module and an electronic device. BACKGROUND

[0003] At present, consumers have higher and higher requirements for the camera function of electronic devices, for example, requiring electronic devices to be able to realize multiple focal lengths to adapt to different shooting scenes. Generally, a multiple focal length optical scheme is to realize focusing by using two or more groups of mirror groups. As shown in FIG. 1, FIG. 1 is a simple schematic diagram of a related motor 20 in the related art, the related motor 20 includes a first bearing frame 21 and a second bearing frame 22, the first bearing frame 21 is used to bear a first moving mirror group 24, and the second bearing frame 22 is used to bear a second moving mirror group 25. The first moving mirror group 24 and the first moving mirror group 24 are arranged along the optical axis direction. In order to improve the movement precision of the moving mirror group, the first bearing frame 21 and the second bearing frame 22 need to be sleeved on a guide rod 23 along the optical axis direction. The guide rod 23 is parallel to the optical axis direction. The first bearing frame 21 and the second bearing frame 22 are in contact with the guide rod 23 and can move along the guide rod 23. In the optical axis direction, the first bearing frame 21 and the second bearing frame 22 need to be long enough in the shaft holding area of the guide rod 23 to avoid or minimize shaking during movement.

[0004] In addition, during movement, the first moving mirror group 24 and the second moving mirror group 25 have a certain inertia due to their own mass, and the greater the mass, the greater the inertia. In order to prevent the first moving mirror group 24 and the second moving mirror group 25 from colliding, the first bearing frame 21 and the second bearing frame 22 also have a certain anti-collision gap in the optical axis direction. When the distance between the first bearing frame 21 and the second bearing frame 22 is the closest in the optical axis direction, the total occupied size of the first bearing frame 21 and the second bearing frame 22 in the optical axis direction is greater than the sum of the occupied size C1 of the first bearing frame 21 in the optical axis direction and the occupied size C2 of the second bearing frame 22 in the optical axis direction. In this way, the related motor 20 occupies a large size in the optical axis direction, which is not conducive to the miniaturization of the electronic device. SUMMARY

[0005] The present application provides a motor device, a camera module and an electronic device which can be beneficial to reduce the occupied size in the optical axis direction.

[0006] In a first aspect, the present application provides a motor device, which comprises a first support, a second support and a first guide shaft. The first support is configured to carry a first lens group, and the first support is provided with a first guide portion, a side wall of the first guide portion being configured to contact the first guide shaft. The second support is configured to carry a second lens group, and the first lens group and the second lens group are arranged along an optical axis direction, and an axial direction of the first guide shaft is parallel to the optical axis direction. The second support is provided with a second guide portion, a side wall of the second guide portion being configured to contact the first guide shaft. The first guide portion and the second guide portion are arranged along a circumferential direction of the first guide shaft, and the first guide portion and the second guide portion are configured to contact the first guide shaft to enable movement along the first guide shaft, and the first guide shaft is parallel to the optical axis direction. When a first top end surface of the first support in the optical axis direction and a second top end surface of the second support in the optical axis direction are closest along the optical axis direction, a projection of the first guide portion in the optical axis direction and a projection of the second guide portion in the optical axis direction overlap.

[0007] The motor device provided by the present application has the following advantages. The first guide portion and the second guide portion are arranged along the circumferential direction of the first guide shaft, and the first guide portion and the second guide portion contact the first guide shaft in different regions along the circumferential direction of the first guide shaft. When the first top end surface and the second top end surface are closest along the optical axis direction, the projection of the first guide portion in the optical axis direction and the projection of the second guide portion in the optical axis direction overlap, that is, the projection of the first support in the optical axis direction and the projection of the second support in the optical axis direction overlap. In this way, the total length of the first support and the second support in the optical axis direction can be less than the sum of the length of the projection of the first support in the optical axis direction and the length of the projection of the second support in the optical axis direction, thereby facilitating reduction of the occupied size of the motor device in the optical axis direction. While the first guide shaft guides the focusing movement of the first lens group and the second lens group, the motor device, the camera module and the electronic device can be miniaturized.

[0008] In addition, in the case of the same occupied size of the motor device in the optical axis direction as that of the related motor, the first guide portion and the second guide portion are arranged along the circumferential direction of the first guide shaft, and the regions where the first guide portion and the second guide portion contact the first guide shaft in the optical axis direction can be longer, thereby facilitating improvement of the support strength of the first guide shaft on the first support and the second support, and thereby facilitating reduction of the possibility of shaking of the first support and the second support when moving relative to the first guide shaft.

[0009] In addition, in the case of the same occupied size of the motor device in the optical axis direction as that of the related motor, the first support and the second support have a larger stroke or a larger range of movement in the optical axis direction, thereby facilitating enhancement of the focusing and / or zooming effect of the camera module having the motor device.

[0010] In a possible implementation manner according to the first aspect, when the first top end surface of the first support and the second top end surface of the second support are closest along the optical axis, the first guide portion can at least partially overlap the second guide portion in the first holding area of the first guide shaft along the circumferential direction of the first guide shaft.

[0011] The first holding area refers to an area occupied by a first end point where the first guide portion contacts the first guide shaft and a second end point where the first guide portion contacts the first guide shaft along the axial direction of the first guide shaft.

[0012] The second holding area refers to an area occupied by a third end point where the second guide portion contacts the first guide shaft and a fourth end point where the second guide portion contacts the first guide shaft along the axial direction of the first guide shaft.

[0013] In the possible implementation manner, since the first guide portion and the second guide portion are arranged along the circumferential direction of the first guide shaft, the first guide portion and the second guide portion contact the first guide shaft in different areas along the circumferential direction of the first guide shaft, respectively. At least in the case where the first top end surface and the second top end surface are closest along the optical axis, the first guide portion and the second guide portion can jointly use the size of the first guide shaft along the optical axis. Compared with a motor device of the related art occupying the same size along the optical axis, the length of the first holding area can be longer, so as to improve the support stability of the first guide shaft to the first support, reduce the possibility of shaking of the first support relative to the first guide shaft, and facilitate increasing the length of the second holding area, so as to improve the support stability of the first guide shaft to the second support, reduce the possibility of shaking of the second support relative to the first guide shaft.

[0014] In a possible implementation manner according to the first aspect, the first guide portion is provided with a first guide groove, and an inner wall of the first guide groove includes a first side wall and a second side wall connected to each other, the first side wall is in contact with the outer wall of the first guide shaft, and the second side wall is configured to be in contact with the outer wall of the first guide shaft. The second guide portion is provided with a second guide groove, and an inner wall of the second guide groove includes a third side wall and a fourth side wall connected to each other, the third side wall is configured to be in contact with the outer wall of the first guide shaft, and the fourth side wall is configured to be in contact with the outer wall of the first guide shaft.

[0015] In the possible implementation manner, since the first side wall and the second side wall of the first guide groove are both in contact with the first guide shaft, the first guide shaft can limit the movement of the first support in the normal direction of the first side wall and the normal direction of the second side wall, so as to facilitate improving the guiding accuracy of the first guide shaft to the movement of the first support. Since the third side wall and the fourth side wall of the second guide groove are both in contact with the first guide shaft, the first guide shaft can limit the movement of the second support in the normal direction of the third side wall and the normal direction of the fourth side wall, so as to facilitate improving the guiding accuracy of the first guide shaft to the movement of the second support.

[0016] According to the first aspect, in one possible implementation, both the first bracket and the second bracket are plastic brackets, the first guide shaft is a metal shaft, and at least one of the first sidewall, the second sidewall, the third sidewall and the fourth sidewall includes a first connecting surface, a recess and a second connecting surface arranged sequentially along the optical axis direction, and the first connecting surface and the second connecting surface are in contact with the first guide shaft.

[0017] Plastic brackets are prone to deformation. Taking the contact between the first sidewall and the first guide shaft as an example, if the first sidewall is a large plane, the first sidewall will warp or dent due to the deformation of the first bracket during assembly and use. The deformed area of ​​the large plane may not be able to contact the first guide shaft, making it difficult for the actual contact length between the large plane and the first guide shaft in the optical axis direction to reach the required contact length. This will affect the support stability of the first guide shaft on the first bracket and easily cause the first bracket to sway when moving relative to the first guide shaft.

[0018] In this possible implementation, by providing recesses on the first, second, third, and fourth sidewalls, and forming first and second connecting surfaces spaced apart in the optical axis direction on each of the first, second, third, and fourth sidewalls, it is beneficial to reduce the deformation influence between the first and second connecting surfaces, allowing the smaller first and second connecting surfaces to make good contact with the first guide shaft. This is beneficial to increasing the effective actual contact area between the first, second, third, and fourth sidewalls and the first guide shaft, and to improving the contact stability between the first and second supports and the first guide shaft, thereby reducing the possibility of swaying when the first and second supports move relative to the first guide shaft.

[0019] According to the first aspect, in one possible implementation, the first guide portion and the second guide portion are arranged opposite to each other.

[0020] In this possible implementation, the first guide portion and the second guide portion are both arranged circumferentially along the first guide shaft and are positioned opposite each other, that is, the first guide portion and the second guide portion stand on opposite sides of the first guide shaft. In this way, the force balance of the first guide shaft is improved, the possibility of the motor device tipping over is reduced, and the stability and reliability of the motor device are improved.

The second bracket also has a second auxiliary portion, the sidewall of which is configured to contact the second guide shaft and be movable along the second guide shaft.

[0022] In this possible implementation, through the joint action of the first guide shaft and the second guide shaft, the stability and smoothness of the first support and the second support can be improved, and the focusing accuracy of the multi-focus section of the camera module can be improved.

[0023] According to the first aspect, the first auxiliary part and the second auxiliary part are arranged along the circumference of the second guide shaft, and the first auxiliary part at least partially overlaps the second auxiliary part in a third bearing area of the second guide shaft.

[0024] The third bearing area refers to an area occupied by a fifth end point at which the first auxiliary part contacts the second guide shaft to a sixth end point at which the first auxiliary part contacts the second guide shaft in the axial direction of the second guide shaft.

[0025] The fourth bearing area refers to an area occupied by a seventh end point at which the second auxiliary part contacts the second guide shaft to an eighth end point at which the second auxiliary part contacts the second guide shaft in the axial direction of the second guide shaft.

[0026] In this possible implementation, since the first auxiliary part and the second auxiliary part are arranged along the circumference of the second guide shaft, the first auxiliary part and the second auxiliary part contact the second guide shaft in different areas along the circumference of the second guide shaft. At least in the case where the first top end surface and the second top end surface are closest to each other along the optical axis, the first auxiliary part and the second auxiliary part can jointly use the size of the second guide shaft in the optical axis direction. Compared with a motor device of the related art that occupies the same size in the optical axis direction, the length of the third bearing area can be longer, so as to improve the support stability of the second guide shaft to the first support, reduce the possibility of shaking of the second support relative to the second guide shaft during movement, and increase the length of the fourth bearing area, so as to improve the support stability of the second guide shaft to the second support and reduce the possibility of shaking of the second support relative to the second guide shaft during movement.

The first contact side wall and the second contact side wall are arranged in parallel, that is, the first auxiliary part and the second auxiliary part are arranged on both sides of the second guide shaft.

[0037] In the possible implementation, the first support and the second support are driven by the at least two groups of driving groups, which is conducive to enhancing the driving power.

[0038] According to the first aspect, in a possible implementation, when the first top end surface of the first support in the optical axis direction and the second top end surface of the second support in the optical axis direction are closest along the optical axis direction, along the circumferential direction of the first bearing portion, the first mounting portion is located between the first end of the first support portion and the first end of the second support portion, and the second mounting portion is located between the second end of the first support portion and the second end of the second support portion.

The thrust on the first guide shaft is distributed on both sides of the first guide shaft, and the thrust on the second guide shaft is distributed on both sides of the second guide shaft, which is conducive to improving the balance of the forces on the first guide shaft and the second guide shaft and reducing the possibility of the motor device overturning.

[0040] In addition, along the circumferential direction of the first bearing portion, the first support portion, the first mounting portion, the second support portion and the second mounting portion are arranged, which maximizes the use of the circumferential space of the motor device and is conducive to further reducing the occupied size of the motor device in the optical axis direction.

[0103] Please refer to FIG. 3, FIG. 4 and FIG. 5, FIG. 3 is a partial structure schematic diagram of some embodiments of the camera module 100, FIG. 4 is an exploded schematic diagram of the partial structure of some embodiments of the camera module 100 shown in FIG. 3, and FIG. 5 is a partial cross-sectional schematic diagram of the camera module 100 along the line B-B of FIG. 3.

[0104] The motor device 1 includes a base 10, a first guide shaft 30, a second guide shaft 40, a first support 52, a second support 54, and a driving component 60. The base 10 is used to carry the first guide shaft 30, the second guide shaft 40, the first support 52, the second support 54, and the driving component 60. The first guide shaft 30 and the second guide shaft 40 are installed on the base 10. The first support 52 and the second support 54 are both in contact with the first guide shaft 30 and can move along the first guide shaft 30. The first support 52 and the second support 54 are also both in contact with the second guide shaft 40 and can move along the second guide shaft 40. The driving component 60 is used to drive the first support 52 and the second support 54 to move along the first guide shaft 30 and the second guide shaft 40 to perform focusing or zooming. The first support 52 has a first top end face 520 in the optical axis direction, and the second support 54 has a second top end face 540 in the optical axis direction. In some embodiments, as shown in FIG. 3, if the base 10 is taken as a reference, the first top end face 520 can be the top face of the first support 52 that is farthest away from the base 10 in the optical axis direction, and the second top end face 540 can be the top face of the second support 54 that is farthest away from the base 10 in the optical axis direction.

[0105] Through the movement of the first support 52 and the second support 54 in the optical axis direction, the distance between the first top end face 520 and the second top end face 540 in the optical axis direction changes from the nearest distance to the farthest distance, thereby driving the distance between the first mirror group 2 and the second mirror group 3 in the optical axis direction to change.

[0106] The first guide shaft 30 and the second guide shaft 40 are used for guiding the movement of the first support 52 and the second support 54, which is beneficial to improve the focusing accuracy of the camera module 100, thereby improving the shooting quality of the camera module 100.

[0107] The base 10 can be mounted on a module circuit board 4 or the like. Please refer to FIG. 5 and FIG. 6, and FIG. 6 is a perspective assembly diagram of the base 10, the first guide shaft 30 and the second guide shaft 40. The base 10 is provided with a through hole 12 for light transmission, so that the light output from the first lens group 2 and the second lens group 3 can pass through the through hole 12 and enter the image sensor 5 (as shown in FIG. 2B). The base 10 is also provided with a first mounting groove 14 and a second mounting groove 16. The first mounting groove 14 is used for mounting the first guide shaft 30, and the second mounting groove 16 is used for mounting the second guide shaft 40. The first mounting groove 14 can be used for mounting and positioning the first guide shaft 30 when the first guide shaft 30 is mounted to the base 10, which is beneficial to improve the assembly convenience between the first guide shaft 30 and the base 10. The second mounting groove 16 can be used for mounting and positioning the second guide shaft 40 when the second guide shaft 40 is mounted to the base 10, which is beneficial to improve the assembly convenience between the second guide shaft 40 and the base 10.

One end of the second guide shaft 40 is mounted in the second mounting groove 16. The first guide shaft 30 is parallel to the second guide shaft 40. The first guide shaft 30 is parallel to the optical axis direction of the first lens group 2. The first guide shaft 30 and the second guide shaft 40 can have the same structure, shape and material. Through the joint action of the first guide shaft 30 and the second guide shaft 40, the stability and smoothness of the movement of the first support 52 and the second support 54 can be improved, which is beneficial to improve the focusing accuracy of the multi-focal segment of the camera module 100. The first support 52 and the second support 54 are in contact with the first guide shaft 30, so as to move along the first guide shaft 30 under the driving of the driving component. The first support 52 and the second support 54 are in contact with the second guide shaft 40, so as to move along the second guide shaft 40 under the driving of the driving component.

[0109] In some embodiments of the present application, the first guide shaft 30 and the second guide shaft 40 each include a first surface 31, a second surface 32, a third surface 33, and a fourth surface 34. The first surface 31 and the third surface 33 are oppositely arranged, and the second surface 32 and the fourth surface 34 are oppositely arranged. The first surface 31 and the third surface 33 are substantially part of a cylindrical surface. The first surface 31 is configured to contact the first support 52, and the third surface 33 is configured to contact the second support 54. The second surface 32 and the fourth surface 34 are substantially planar structures. The second surface 32 is substantially parallel to the fourth surface 34. In this way, the cross-sectional profile of the first guide shaft 30 and the second guide shaft 40 is substantially in the shape of a runway, so as to reduce the occupied size of the first guide shaft 30 and the second guide shaft 40 in the vertical axial plane, and to avoid unnecessary interference with the guiding movement. In manufacturing the first guide shaft 30 and the second guide shaft 40, a circular shaft can be partially removed along the axial direction of the guide shaft to form a guide shaft in the shape of a runway. The present application does not limit the shape and structure of the first guide shaft 30 and the second guide shaft 40, and the shape, structure, and manufacturing material of the first guide shaft 30 and the second guide shaft 40 can be different. For example, at least one of the first guide shaft 30 and the second guide shaft 40 can be a cuboid, a cylinder, or a polygonal prism, etc.

[0110] Please refer to FIG. 5, FIG. 7, and FIG. 8. FIG. 7 is a perspective exploded view of the first support 52 and the second support 54, and FIG. 8 is another perspective exploded view of the first support 52 and the second support 54.

[0111] The first support 52 includes a first bearing portion 521, a first support portion 523, a second support portion 524, a first guide portion 525, and a first auxiliary portion 526.

In some embodiments of the present application, the first guiding portion 525 is connected to the first end of the first support portion 523. A second gap 528 is formed between the second end of the first support portion 523 and the second end of the second support portion 524, and is configured to accommodate a portion of the second holder 54. Since the portion of the second holder 54 can be accommodated in the first gap 527 and the second gap 528, i.e., the second holder 54 uses the space of the first holder 52 in the circumferential direction of the first holder 52, it is beneficial to reduce the occupied space of the motor device 1, and further beneficial to miniaturize the motor device 1.

[0114] The first auxiliary portion 526 is protruded from the periphery of the first bearing portion 521, and is configured to contact the second guide shaft 40 to allow the first holder 52 to move along the second guide shaft 40.

The present application does not limit the structure of the first bearing portion 521 and the second bearing portion 541. The second top end surface 540 is located on the side of the second bearing portion 541 away from the base 10. It can be understood that the present application does not limit the second top end surface 540 on the second bearing portion 541.

[0116] Exemplarily, the first mounting portion 543 and the second mounting portion 544 are both protruded from the second bearing portion 541 and arranged along the circumferential direction of the second bearing portion 541. The first mounting portion 543 and the second mounting portion 544 are configured to support part of the driving component 60.

[0117] The first mounting portion 543 is formed with a first recess 5432 (as shown in FIG. 7) on the side of the second bearing portion 541 away from the second bearing portion 541 in the radial direction, and is configured to accommodate the second guiding portion 545. The first recess 5432 can avoid interference with other structures of the motor device 1 when the first support 52 moves. The second guiding portion 545 is protruded from the inner wall of the first recess 5432, which is beneficial to reduce the radial size of the second support 54. It can be understood that the first mounting portion 543 can omit the first recess 5432, and the second guiding portion 545 is protruded from the outer wall of the first mounting portion 543.

[0118] The second installation portion 544 is formed with a second recess 5442 (as shown in FIG. 8) on a side of the second bearing portion 541 away from the second bearing portion 541 in the radial direction, for accommodating the first auxiliary portion 526 and disposing the second auxiliary portion 546, so as to reduce the occupied size of the second holder 54 in the radial direction.

In some embodiments of the present application, the inner wall of the second recess 5442 comprises a first inner wall 5443 and a second inner wall 5444 connected and disposed, the second auxiliary portion 546 is protruded from the first inner wall 5443 and can be in contact with the first bearing portion 521 in the optical axis direction, so as to limit the stroke of the first holder 52 and the second holder 54 in the optical axis direction. The second inner wall 5444 is disposed opposite to and spaced apart from the first auxiliary portion 526. Since the first auxiliary portion 526 and the second auxiliary portion 546 can be accommodated in the second recess 5442 of the second holder 54, it is beneficial to reduce the occupied space of the motor device 1 in the radial direction of the second bearing portion 541.

[0119] The second guide portion 545 is disposed on the inner wall of the first recess 5432, and the second guide portion 545 is used to contact the first guide shaft 30, so that the second holder 54 can move along the first guide shaft 30.

[0120] The second auxiliary portion 546 is disposed in the second recess 5442. The second auxiliary portion 546 is used to contact the second guide shaft 40, so that the second holder 54 can move along the second guide shaft 40. In some embodiments of the present application, the second auxiliary portion 546 is substantially in the shape of “L”, and the second auxiliary portion 546 comprises a third portion 5461 and a fourth portion 5463 connected with each other, and one end of the third portion 5461 is connected to the second inner wall 5444. The side of the third portion 5461 facing the first bearing portion 521 is formed with a limiting groove 5465 for accommodating the first portion 5261.

[0122] When the first holder 52 and the second holder 54 are assembled together, the axis of the first light passage hole 522 and the axis of the second light passage hole 542 are substantially located on the optical axis of the camera module 100.

[0123] Exemplarily, the first bearing part 521 and the second bearing part 541 are arranged along the axial direction of the first bearing part 521, the first support part 523 and the second support part 524 are arranged around the periphery of the first bearing part 521, and the first mounting part 543 and the second mounting part 544 are arranged around the periphery of the second bearing part 541. When the first top end surface 520 of the first bracket 52 in the optical axis direction is closest to the second top end surface 540 of the second bracket 54 in the optical axis direction, the first mounting part 543 can be located in the first gap 527 and the second mounting part 544 can be located in the second gap 528 along the circumferential direction of the first bearing part 521, that is, the first mounting part 543 is located between the first end of the first support part 523 and the first end of the second support part 524, and the second mounting part 544 is located between the second end of the first support part 523 and the second end of the second support part 524, so as to maximize the use of the circumferential space of the motor device 1, facilitate the reduction of the occupied space of the motor device 1, and further facilitate the miniaturization of the motor device 1.

[0124] When the first bracket 52 and the second bracket 54 are assembled together, the first auxiliary part 526 can be accommodated in the second recess 5442, the first part 5261 can be accommodated in the limiting groove 5465, and the fourth part 5463 can be located between the first inner wall 5443 and the second part 5263. The second part 5263 and the fourth part 5463 can be arranged opposite to each other. The first contact side wall 5265 and the second contact side wall 5467 can be arranged opposite to and spaced from each other. Since the first part 5261 can be accommodated in the limiting groove 5465, the limiting groove 5465 can limit the movement stroke of the first bracket 52 and the second bracket 54 in the optical axis direction, so as to reduce the possibility of the first bracket 52 and the second bracket 54 being separated when the electronic device 1000 is subjected to a large impact due to falling or other factors during transportation or use, and facilitate the improvement of the reliability of the motor device 1.

[0125] It can be understood that the present application does not limit the first support part 523 and the second support part 524 to be arranged around the periphery of the first bearing part 521, for example, the first support part 523 and the second support part 524 can be directly arranged on the end surface of the first bearing part 521 in the optical axis direction.

[0126] It can be understood that the present application does not limit the first mounting part 543 and the second mounting part 544 to be arranged around the periphery of the second bearing part 541, for example, the first mounting part 543 and the second mounting part 544 can be directly arranged on the end surface of the second bearing part 541 in the optical axis direction.

[0127] It can be understood that the second recess 5442 can be omitted, and the second auxiliary part 546 can be arranged on the outer wall of the second mounting part 544. The third part 5461 is formed with a limiting groove 5465 towards one side of the first bearing part 521, and the limiting groove 5465 is used to accommodate the first part 5261.

[0128] In some embodiments of the present application, referring to FIG. 12, FIG. 13 and FIG. 14, FIG. 12 is a top view of the camera module 100 shown in FIG. 3, FIG. 13 is a perspective view of the camera module 100 shown in FIG. 3 from another angle, and FIG. 14 is a simple schematic diagram of the partial structure of the camera module 100 in a certain state. The first guide part 525 and the second guide part 545 are arranged along the circumference of the first guide shaft 30, and the first guide shaft 30 is parallel to the optical axis direction. When the first top end surface 520 of the first support 52 (as shown in FIG. 13) and the second top end surface 540 of the second support 54 (as shown in FIG. 13) are closest along the optical axis direction, the orthogonal projection of the first guide part 525 along the optical axis direction and the orthogonal projection of the second guide part 545 along the optical axis direction overlap.

[0129] In the motor device 1 provided by the present application, the first guide part 525 and the second guide part 545 are arranged along the circumference of the first guide shaft 30, and the first guide part 525 and the second guide part 545 respectively contact the first guide shaft 30 at different regions along the circumference of the first guide shaft 30. When the first top end surface 520 of the first support 52 and the second top end surface 540 of the second support 54 are closest along the optical axis direction, the orthogonal projection of the first guide part 525 along the optical axis direction and the orthogonal projection of the second guide part 545 along the optical axis direction overlap, that is, the orthogonal projection of the first support 52 along the optical axis direction and the orthogonal projection of the second support 54 along the optical axis direction overlap. In this way, the length occupied by the first support 52 and the second support 54 along the optical axis direction can be less than the sum of the length of the orthogonal projection of the first support 52 along the optical axis direction and the length of the orthogonal projection of the second support 54 along the optical axis direction, which is conducive to reducing the size of the motor device 1 along the optical axis direction, and facilitating the miniaturization development of the motor device 1, the camera module 100 and the electronic equipment 1000 while guiding the focusing movement of the first lens group 2 and the second lens group 3 through the first guide shaft 30. In addition, in the motor device 1 provided by the present application, the stroke or the range of movement of the first support 52 and the second support 54 along the optical axis direction is larger than that of the related motor in the related art under the same size occupied by the motor along the optical axis direction. In this way, it is conducive to enhancing the focusing and / or zooming effect of the camera module 100 with the motor device 1, and improving the photographing quality of the camera module 100 and the electronic equipment 1000.

[0130] In some embodiments of the present application, when the first top end surface 520 of the first support 52 (as shown in FIG. 13) and the second top end surface 540 of the second support 54 (as shown in FIG. 13) are closest in the direction of the optical axis, the first guide portion 525 at least partially overlaps the second guide portion 545 in the first bearing region D1 (as shown in FIGS. 13 and 14) of the first guide shaft 30 and in the second bearing region D2 (as shown in FIGS. 13 and 14) of the first guide shaft 30.

[0131] In the case where the first top end surface 520 and the second top end surface 540 are closest in the direction of the optical axis, the first guide portion 525 and the second guide portion 545 can jointly use the size of the first guide shaft 30 in the direction of the optical axis. Compared with a motor device of the related art occupying the same size in the direction of the optical axis, the length of the first bearing region D1 can be longer, so as to improve the support stability of the first guide shaft 30 to the first support 52, reduce the possibility of shaking of the first support 52 relative to the first guide shaft 30, and facilitate increasing the length of the second bearing region D2, so as to improve the support stability of the first guide shaft 30 to the second support 54, reduce the possibility of shaking of the second support 54 relative to the first guide shaft 30.

[0132] The first guide portion 525 in the first bearing region D1 of the first guide shaft 30 refers to the region occupied by the first end point J1 (as shown in FIG. 14) where the first guide portion 525 contacts the first guide shaft 30 to the second end point J2 (as shown in FIG. 14) where the first guide portion 525 contacts the first guide shaft 30 in the axial direction of the first guide shaft 30.

[0133] The second guide portion 545 in the second bearing region D2 of the first guide shaft 30 refers to the region occupied by the third end point J3 (as shown in FIG. 14) where the second guide portion 545 contacts the first guide shaft 30 to the fourth end point J4 (as shown in FIG. 14) where the second guide portion 545 contacts the first guide shaft 30 in the axial direction of the first guide shaft 30.

[0134] The bearing region of the first guide portion 525 in the first guide shaft 30 is the bearing region of the first support 52 in the first guide shaft 30. The bearing region of the second guide portion 545 in the first guide shaft 30 is the bearing region of the second support 54 in the first guide shaft 30.

[0135] Since the first bracket 52 and the second bracket 54 are both capable of moving relative to the first guide shaft 30 and the second guide shaft 40, the first clamping region D1 and the second clamping region D2 can not overlap in some states of the motor device 1, and the first clamping region D1 and the second clamping region D2 can overlap in other states of the motor device 1. When the first clamping region D1 and the second clamping region D2 overlap, the first guide portion 525 is at least partially overlapped with the first clamping region D1 and the second clamping region D2 for thinner electronic devices 1000 such as mobile phones, tablets, etc. or electronic devices 1000 with higher requirements for the size in the optical axis direction, so as to reduce the size occupied in the optical axis direction.

[0136] The contact between the first guide portion 525 and the first guide shaft 30 includes at least one of rolling contact and sliding contact. The friction of the rolling contact and the sliding contact both helps to improve the smoothness of the relative movement between the first guide portion 525 and the first guide shaft 30.

[0137] It can be understood that when the first top end surface 520 of the first bracket 52 (as shown in FIG. 13) and the second top end surface 540 of the second bracket 54 (as shown in FIG. 13) are closest in the optical axis direction, the first clamping region D1 (as shown in FIGS. 13 and 14) and the second clamping region D2 can not overlap. Please refer to FIGS. 13, 15 and 16, FIG. 15 is an enlarged schematic view of the local region I of FIG. 12, and FIG. 16 is a schematic view of the first bracket 52.

[0138] In some embodiments of the present application, the first guide portion 525 is provided with a first guide groove 5254 for contacting the first surface 31 of the first guide shaft 30. When the first bracket 52 and the second bracket 54 are assembled together, the first guide groove 5254 is located on the side of the first guide portion 525 facing the second guide portion 545. The first guide groove 5254 can be a V-shaped groove. The plane in which the cross-sectional profile of the first guide groove 5254 lies is perpendicular to the optical axis direction. The inner wall of the first guide groove 5254 includes a first side wall 5255 and a second side wall 5256 that are connected to each other, the first side wall 5255 is used to contact the first surface 31 of the first guide shaft 30, and the second side wall 5256 is used to contact the first surface 31 of the first guide shaft 30. In some embodiments, the first side wall 5255 and the second side wall 5256 are in sliding contact with the first surface 31 of the first guide shaft 30, i.e., the first side wall 5255 and the second side wall 5256 are in line contact with the first surface 31 of the first guide shaft 30. In the optical axis direction, the first side wall 5255 and the second side wall 5256 are in the first clamping region D1 of the first guide shaft 30. It can be understood that the first side wall 5255 and the second side wall 5256 can not be the same in the clamping region of the first guide shaft 30, and the regions of the first guide portion 525 that contact the first guide shaft 30 in the optical axis direction are combined to form the first clamping region D1.

[0139] Since the first side wall 5255 and the second side wall 5256 of the first guide groove 5254 are both used to contact the first surface 31 of the first guide shaft 30, the first guide shaft 30 can limit the movement of the first support 52 in the normal direction of the first side wall 5255 and the normal direction of the second side wall 5256, can reduce the possibility of shaking of the first support 52 when moving in the optical axis direction, and is conducive to improving the guiding accuracy of the first guide shaft 30 to the movement of the first support 52, thereby improving the focusing accuracy of the camera module 100 and the image quality of the electronic device 1000. In some embodiments of the present application, the first side wall 5255 is in sliding contact with the first surface 31 of the first guide shaft 30, and the second side wall 5256 is in sliding contact with the first surface 31 of the first guide shaft 30. The first surface 31 of the first guide shaft 30 is a partial cylindrical surface, and the first side wall 5255 is in line contact with the first guide shaft 30, which is conducive to reducing the friction between the first side wall 5255 and the first guide shaft 30, thereby facilitating the smoothness of the relative movement between the first side wall 5255 and the first guide shaft 30.

[0140] Along the circumference of the first guide groove 5254, the first side wall 5255 and the second side wall 5256 can be directly connected or connected through other connecting walls. The shape of the first guide groove 5254 is not limited in the present application, and the inner wall of the first guide groove 5254 can be in contact with the outer wall of the first guide shaft 30. In some embodiments of the present application, the first guide part 525 can omit the first guide groove 5254, and the first guide part 525 can be in contact with the outer wall of the first guide shaft 30. It can be understood that the contact between the first guide shaft 30 and the first guide part 525 of the first support 52 can include at least one of surface contact, line contact, and multi-point contact.

[0141] Referring to FIG. 13 and FIG. 17, the second guide portion 545 is provided with a second guide groove 5454 for contacting the third surface 33 of the first guide shaft 30. When the first bracket 52 and the second bracket 54 are assembled together, the second guide groove 5454 is located on the side of the second guide portion 545 facing the second guide portion 545. The second guide groove 5454 can be a V-shaped groove. The plane in which the cross-sectional profile of the second guide groove 5454 lies is perpendicular to the first direction. The inner wall of the second guide groove 5454 includes a third side wall 5455 and a fourth side wall 5456, which are connected to each other, the third side wall 5455 being configured to contact the outer wall of the second guide shaft 40, and the fourth side wall 5456 being configured to contact the outer wall of the second guide shaft 40. In some embodiments, the third side wall 5455 and the fourth side wall 5456 are in sliding contact with the third surface 33 of the first guide shaft 30, i.e., the first side wall 5255 and the second side wall 5256 are in line contact with the third surface 33 of the first guide shaft 30. In the optical axis direction, the third side wall 5455 and the fourth side wall 5456 are in the second clamping region D2 of the first guide shaft 30.

[0142] Since the third side wall 5455 and the fourth side wall 5456 of the second guide groove 5454 are both configured to contact the third surface 33 of the first guide shaft 30, the second guide shaft 40 can restrict the movement of the second bracket 54 in the normal direction of the third side wall 5455 and the normal direction of the fourth side wall 5456, thereby reducing the possibility of the first bracket 52 shaking when moving in the optical axis direction, and improving the guiding accuracy of the first guide shaft 30 for the movement of the second bracket 54. In some embodiments of the present application, the third side wall 5455 is in sliding contact with the third surface 33 of the first guide shaft 30, and the fourth side wall 5456 is in sliding contact with the third surface 33 of the first guide shaft 30. The third surface 33 of the first guide shaft 30 can be a partial cylindrical surface, and the third side wall 5455 is in line contact with the first guide shaft 30, which is conducive to reducing the friction between the third side wall 5455 and the first guide shaft 30, and improving the smoothness of the relative movement between the third side wall 5455 and the first guide shaft 30.

[0143] In the circumferential direction of the second guide groove 5454, the third side wall 5455 and the fourth side wall 5456 can be directly connected or connected through other connecting walls. The shape of the second guide groove 5454 is not limited in the present application, and the inner wall of the second guide groove 5454 can be in contact with the outer wall of the first guide shaft 30. In some embodiments of the present application, the second guide groove 5454 can be omitted from the second guide portion 545, and the second guide portion 545 can be in contact with the outer wall of the second guide shaft 40. It can be understood that the contact between the first guide shaft 30 and the second guide portion 545 can include at least one of surface contact, line contact, and multi-point contact.

[0144] In some embodiments of the present application, the first support 52 and the second support 54 are plastic supports, and the first guide shaft 30 is a metal shaft. The plastic support has a certain amount of deformation. For example, if the first side wall 5255 is a large flat surface, when the first support 52 is assembled with the first guide shaft 30 and in use, some areas of the first side wall 5255 will be deformed, such as warped or concave, due to the deformation of the first support 52. The deformed areas of the large flat surface can not be in contact with the first guide shaft 30, so that the actual contact area between the large flat surface and the first guide shaft 30 in the optical axis direction can not reach the required contact area, which can affect the stability of the support of the first guide shaft 30 on the first support 52, and can easily cause the first support 52 to shake when moving relative to the first guide shaft 30.

[0145] Therefore, referring again to FIGS. 16 and 17, FIG. 17 is a perspective view of the second support 54. The first side wall 5255, the second side wall 5256, the third side wall 5455, and the fourth side wall 5456 each include a first connecting surface 5257, a concave portion 5258, and a second connecting surface 5259 arranged in sequence along the optical axis direction. The second connecting surface 5259 is closer to the base 10 than the first connecting surface 5257. The first connecting surface 5257 and the second connecting surface 5259 are used to contact the first guide shaft 30. By arranging the concave portion 5258 on the first side wall 5255, the second side wall 5256, the third side wall 5455, and the fourth side wall 5456, the first side wall 5255, the second side wall 5256, the third side wall 5455, and the fourth side wall 5456 each form the first connecting surface 5257 and the second connecting surface 5259 arranged in sequence along the optical axis direction, which can reduce the deformation influence between the first connecting surface 5257 and the second connecting surface 5259, so that the first connecting surface 5257 and the second connecting surface 5259 with a smaller area can be in good contact with the first guide shaft 30, thereby increasing the effective actual contact area between the first side wall 5255, the second side wall 5256, the third side wall 5455, the fourth side wall 5456, and the first guide shaft 30, and reducing the possibility of shaking of the first support 52 and the second support 54 when moving relative to the first guide shaft 30. The concave portions 5258 of the first side wall 5255 and the second side wall 5256 can be connected or not connected, and the concave portions 5258 of the third side wall 5455 and the fourth side wall 5456 can be connected or not connected.

[0146] It can be understood that the application does not limit the material of the first support 52, the second support 54 and the first guide shaft 30, and the application does not limit the distribution position and the number of the recesses 5258 in the first side wall 5255, the second side wall 5256, the third side wall 5455 and the fourth side wall 5456. At least one of the first side wall 5255, the second side wall 5256, the third side wall 5455 and the fourth side wall 5456 can be provided with the recess 5258.

[0147] Please refer to FIG. 18, FIG. 19A and FIG. 19B, FIG. 18 is an enlarged schematic view of the partial region II of FIG. 12, FIG. 19A is a perspective view of the camera module 100 shown in FIG. 3 from another angle, and FIG. 19B is an enlarged schematic view of a partial region III of FIG. 19A. The first auxiliary part 526 and the second auxiliary part 546 are arranged along the circumference of the second guide shaft 40, and the first auxiliary part 526 and the second auxiliary part 546 are both used to contact the second guide shaft 40. When the first top end surface 520 of the first support 52 and the second top end surface 540 of the second support 54 are closest in the direction of the optical axis, the first auxiliary part 526 in the third holding region D3 of the second guide shaft 40 can at least partially overlap with the second auxiliary part 546 in the fourth holding region D4 of the second guide shaft 40. It can be understood that the contact between the first auxiliary part 526, the second auxiliary part 546 and the second guide shaft 40 includes at least one of rolling contact and sliding contact. The friction of the rolling contact and the sliding contact is both conducive to improving the smoothness of the relative movement between the first guide part 525 and the first guide shaft 30.

[0148] The first auxiliary part 526 in the third holding region D3 of the second guide shaft 40 refers to the region occupied by the fifth end point J5 (as shown in FIG. 14 and FIG. 19B) at which the first auxiliary part 526 contacts the second guide shaft 40 to the sixth end point J6 (as shown in FIG. 14 and FIG. 19B) at which the first auxiliary part 526 contacts the second guide shaft 40 in the axial direction of the second guide shaft 40. The second auxiliary part 546 in the fourth holding region D4 of the second guide shaft 40 refers to the region occupied by the seventh end point J7 (as shown in FIG. 14 and FIG. 19B) at which the second auxiliary part 546 contacts the second guide shaft 40 to the eighth end point J8 (as shown in FIG. 14 and FIG. 19B) at which the second auxiliary part 546 contacts the second guide shaft 40 in the axial direction of the second guide shaft 40. The holding region of the first auxiliary part 526 in the second guide shaft 40 is the third holding region D3 of the first support 52 in the second guide shaft 40. The holding region of the second auxiliary part 546 in the second guide shaft 40 is the fourth holding region D4 of the second support 54 in the first guide shaft 30.

[0149] In some embodiments of the present application, the first contact side wall 5265 is provided with a first contact boss 5268, the first contact boss 5268 is in sliding contact with the first surface 31 of the second guide shaft 40, and the first contact boss 5268 is in the shaft holding area of the second guide shaft 40. The second contact side wall 5467 is provided with a second contact boss 5468, the second contact boss 5468 is in sliding contact with the third surface 33 of the second guide shaft 40, and the second contact boss 5468 is in the shaft holding area of the second guide shaft 40.

[0150] The first contact side wall 5265 is in contact with the second guide shaft 40 through the first contact boss 5268, that is, the first contact boss 5268 is a partial area of the first contact side wall 5265. The area of the first contact boss 5268 is relatively small compared to the large area of the first contact side wall 5265. The first contact boss 5268 is less affected by the deformation of the first support 52, and the contact between the first contact boss 5268 and the second guide shaft 40 in the optical axis direction is more stable, thereby facilitating an increase in the effective actual contact area between the first support 52 and the second guide shaft 40 and reducing the possibility of shaking when the first support 52 moves relative to the second guide shaft 40.

[0151] The second contact side wall 5467 is in contact with the second guide shaft 40 through the second contact boss 5468 with a small area, which facilitates an increase in the effective contact area between the second support 54 and the second guide shaft 40 and reduces the possibility of shaking when the second support 54 moves relative to the second guide shaft 40.

[0152] When the first support 52 and the second support 54 move along the first guide shaft 30, the first support 52 and the second support 54 can move along the second guide shaft 40. In some embodiments, the contact between the second guide portion 545 and the second guide shaft 40 includes at least one of surface contact, line contact, and multi-point contact.

[0153] The first auxiliary portion 526 and the second auxiliary portion 546 are in contact with the second guide shaft 40, so that the first support 52 and the second support 54 can coincide or overlap in the shaft holding area of the second guide shaft 40. This facilitates a reduction in the length of the second guide shaft 40, that is, the length of the motor device 1 in the optical axis direction can be reduced. While the second guide shaft 40 guides the focusing movement of each lens group, it is beneficial to the miniaturization of the motor device 1, the camera module 100, and the electronic device 1000.

[0154] The first contact side wall 5265 and the second contact side wall 5467 can be in contact with the second guide shaft 40, and the second guide shaft 40 limits the movement of the first support 52 in the normal direction of the first contact side wall 5265 and the movement of the second support 54 in the normal direction of the second contact side wall 5467. The first guide shaft 30 can limit the movement of each support in two degrees of freedom in the normal direction of the first side wall 5255 and the normal direction of the second side wall 5256, and the second guide shaft 40 can limit the movement of each support in one degree of freedom in the normal direction of the contact side wall. Therefore, in the first guide shaft 30 and the second guide shaft 40, the first guide shaft 30 can be regarded as “fine” guiding of the support, and the second guide shaft 40 can be regarded as “coarse” guiding of the support. Compared with “coarse” guiding, “fine” guiding has higher requirements for manufacturing and assembly tolerances during manufacturing. Therefore, compared with a guiding scheme in which all guides are “fine” guides, the application combines “coarse” guiding and “fine” guiding. Under the joint action of the “fine” guiding of the first guide shaft 30 and the “coarse” guiding of the second guide shaft 40, it is beneficial to improve focusing accuracy while simplifying the structure of the motor device 1 and reducing the manufacturing difficulty of the motor device 1.

[0155] It can be understood that the application does not limit the arrangement of the first auxiliary part 526 of the first support 52 and the second auxiliary part 546 of the second support 54 along the circumference of the second guide shaft 40. For example, the first auxiliary part 526 of the first support 52 can be sleeved on the second guide shaft 40, and the second auxiliary part 546 of the second support 54 can be sleeved on the second guide shaft 40. It can be understood that the application does not limit the specific structure of the first support 52 and the second support 54. For example, the first support 52 and the second support 54 can both omit the second guide shaft 40, the first guide part 525 and the second guide part 545 are arranged along the circumference of the first guide shaft 30, and the first guide part 525 and the second guide part 545 are in contact with the first guide shaft 30 and can move along the first guide shaft 30.

[0156] It can be understood that the application does not limit the number of supports, the specific structure of the supports, and the shape and structure of the first guide shaft 30 and the second guide shaft 40. The following is a simple description of the cooperation of the first guide shaft 30 and N supports.

[0157] For example, refer to FIG. 20, which is a schematic view of the cooperation of the first support 52, the second support 54, and the first guide shaft 30 of the first shape provided by some embodiments of the application. The first guide shaft 30 can be a flat shaft, the first support 52 is in linear contact with the first guide shaft 30 at one end in the width direction of the first guide shaft 30, the second support 54 is in linear contact with the first guide shaft 30 at the other end in the width direction of the first guide shaft 30, and the end of the first guide shaft 30 in the width direction of the first guide shaft 30 includes a curved surface.

[0158] For example, please refer to FIG. 21, which is a schematic diagram of the cooperation between the first support 52, the second support 54 and the first guide shaft 30 of the second shape according to some embodiments of the present application. The first support 52 and the first guide shaft 30 are in linear contact at one end of the width direction of the first guide shaft 30, and the second support 54 and the first guide shaft 30 are in linear contact at the other end of the width direction of the first guide shaft 30. The difference between the first guide shaft 30 shown in FIG. 21 and the first guide shaft 30 shown in FIG. 20 is that the end of the width direction of the first guide shaft 30 shown in FIG. 21 includes a curved surface and a flat surface.

[0159] For example, please refer to FIG. 22, which is a schematic diagram of the cooperation between the first support 52, the second support 54 and the first guide shaft 30 of the third shape according to some embodiments of the present application. The first guide shaft 30 of the third shape is a cylinder, and the first support 52 and the second support 54 are in contact with the cylindrical surface of the cylinder.

[0160] For example, please refer to FIG. 23, which is a schematic diagram of the cooperation between three supports and the first guide shaft 30 of the fourth shape according to some embodiments of the present application. N can be equal to 3, and the three supports include the first support 52, the second support 54 and the third support 57. The first support 52, the second support 54 and the third support 57 are arranged along the circumferential direction of the first guide shaft 30. The first guide shaft 30 includes the first surface 31, the second surface 32 and the third surface 33. The first support 52 is in linear contact with the first surface 31, the second support 54 is in linear contact with the second surface 32, and the third support 57 is in linear contact with the third surface 33.

[0161] For example, please refer to FIG. 24, which is a schematic diagram of the cooperation between four supports and the first guide shaft 30 of the fifth shape according to some embodiments of the present application. N can be equal to 4, and the four supports include the first support 52, the second support 54, the third support 57 and the fourth support 58. The first support 52, the second support 54, the third support 57 and the fourth support 58 each include a guide portion. The guide portion of the first support 52, the guide portion of the second support 54, the guide portion of the third support 57 and the guide portion of the fourth support 58 are arranged along the circumferential direction of the first guide shaft 30. The first guide shaft 30 includes the first surface 31, the second surface 32, the third surface 33 and the fourth surface 34. The first surface 31, the second surface 32, the third surface 33 and the fourth surface 34 are all curved surfaces. The guide portion of the first support 52 is in linear contact with the first surface 31, the guide portion of the second support 54 is in linear contact with the second surface 32, the guide portion of the third support 57 is in linear contact with the third surface 33, and the guide portion of the fourth support 58 is in linear contact with the fourth surface 34. The examples shown in FIGS. 20-24 also apply to N supports and cooperation with the second guide shaft 40.

[0162] Each support is provided with a guide portion, the guide portions of the N supports are arranged along the circumference of the first guide shaft 30, and the guide portions of the N supports are in contact with the first guide shaft 30 to be capable of moving along the first guide shaft 30. That is, the N supports can share the same first guide shaft 30. The guide portions of the N supports in at least two of the shaft-holding regions of the first guide shaft 30 can coincide or overlap.

[0170] In some embodiments of the present application, please refer to FIG. 25A again. The coil 64 of the first driving group 611 is arranged on the side of the first support portion 523 away from the first bearing portion 521 in the radial direction of the first bearing portion 521, and the magnetic member 63 in the first driving group 611 is arranged face-to-face with the coil 64 of the first driving group 611.

[0174] The first driving group 611, the third driving group 621, the second driving group 612, and the fourth driving group 622 are arranged in the circumferential direction of the second holder 54. As shown in the top view of the camera module 100 in FIG. 25A, the center of the winding plane of the coil 64 of the first driving group 611 and the center of the winding plane of the coil 64 of the second driving group 612 are arranged in a cross manner, and the center of the winding plane of the coil 64 of the third driving group 621 and the center of the winding plane of the coil 64 of the fourth driving group 622 are arranged in a cross manner. The thrust force on the first guide shaft 30 is distributed on both sides of the first guide shaft 30, and the thrust force on the second guide shaft 40 is distributed on both sides of the second guide shaft 40, which is conducive to improving the balance of the forces on the first guide shaft 30 and the second guide shaft 40 and reducing the possibility of the motor device 1 tipping over.

[0176] In this way, the resultant force center of the first driving group 611 and the second driving group 612 on the first guide shaft 30 or the second guide shaft 40 can be at the rotation center or the gravity center of the motor device 1, the resultant force center of the third driving group 621 and the fourth driving group 622 on the first guide shaft 30 or the second guide shaft 40 can be at the rotation center or the gravity center of the motor device 1, unnecessary components can be reduced, the torque of the first guide shaft 30 and the second guide shaft 40 is more balanced, the force arm is reduced, the movement of the first support 52 and the second support 54 in the optical axis direction is more stable, the balance of the torque of the motor device 1 is improved, the possibility of the motor device 1 being tilted is reduced, and the movement stability of the motor device 1 is improved. Since the resultant force center of the first driving group 611 and the second driving group 612 on the first guide shaft 30 or the second guide shaft 40 can be at the rotation center or the gravity center of the motor device 1, the resultant force center of the third driving group 621 and the fourth driving group 622 on the first guide shaft 30 or the second guide shaft 40 can be at the rotation center or the gravity center of the motor device 1, unnecessary components can be reduced, the force arm is reduced, and the movement stability of the motor device 1 is better.
