[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0036] Please refer to Figures 1 - 8 , in a first aspect, an embodiment of this application provides a folding device, including a main body 100, a housing 200, a mounting plate 300, a tipping drive assembly 400, and a folding drive assembly 500.

[0037] Among them, the main body 100 is used to be connected to the vehicle body; the housing 200 has a first end and a second end, at least part of the main body 100 penetrates through the first end of the housing 200, and the housing 200 can rotate relative to the main body 100 around a first axis; the mounting plate 300 is arranged at the second end of the housing 200, a tipping shaft 1 is arranged on the housing 200, the tipping shaft 1 is fixed to the mounting plate 300, and the mounting plate 300 is rotatably connected to the housing 200 through the tipping shaft 1 and can rotate relative to the housing 200 around a second axis, and a rearview mirror is to be arranged on the mounting plate 300.

[0038] Specifically, the first axis and the second axis are preferably perpendicular to each other. The first axis is the folding axis of the rearview device of the vehicle, and the second axis is the tipping axis of the rearview device. One end of the main body 100 is fixed to the vehicle body, the other end of the main body 100 penetrates through the first end of the housing 200 and extends into the housing 200. The main body 100 is preferably arranged in a columnar structure, which is used as a mounting center tube and is hollow inside for passing wires.

[0039] The central axis of the main body 100 is set as the first axis, enabling the housing 200 to rotate around the central axis of the main body 100 to complete the folding action of the rear-view device. The mounting plate 300 is rotationally and cooperatively connected to the housing 200 through a turning shaft 1, that is, with the central axis of the turning shaft 1 as the second axis, enabling the mounting plate 300 to rotate following the turning shaft 1, achieving the rotation of the mounting plate 300 around the central axis of the turning shaft 1 to complete the flipping action of the rear-view device.

[0040] Among them, both the flipping drive assembly 400 and the folding drive assembly 500 are arranged inside the housing 200. The flipping drive assembly 400 is used to drive the mounting plate 300 to rotate around the second axis, and the folding drive assembly 500 is used to drive the housing 200 to rotate around the first axis; among them, the flipping drive assembly 400 and the folding drive assembly 500 are independently arranged.

[0041] Specifically, the flipping drive assembly 400 and the folding drive assembly 500 that work independently are arranged inside the housing 200. The flipping drive assembly 400 and the folding drive assembly 500 have no mechanical coupling, and their layout is reasonable. The flipping drive assembly 400 and the folding drive assembly 500 can act independently, being suitable for meeting the requirements of complex motion scenarios of the rear-view device. Moreover, the independent transmission of the flipping drive assembly 400 and the folding drive assembly 500 avoids the error accumulation caused by motion interference, ensures the positioning accuracy of each degree of freedom, and after a single drive assembly fails, it does not affect the function of the other drive assembly, avoiding the mutual influence of the transmission structures of the flipping drive assembly 400 and the folding drive assembly 500, and improving the system reliability and service life.

[0042] Optionally, referring to Figure 3 , the flipping drive assembly 400 includes a flipping drive member 401, a flipping gear 402, a first gear set 403, and a flipping limit gear 404. Among them, the flipping gear 402 is connected to the flipping drive member 401 through the first gear set 403; the flipping limit gear 404 is arranged on the side of the flipping gear 402 close to the main body 100. Both the flipping limit gear 404 and the flipping gear 402 are sleeved on the turning shaft 1, and the flipping limit gear 404 is in limit sliding fit with the turning shaft 1; among them, one end of the turning shaft 1 arranged outside the housing 200 is fixed to the mounting plate 300. A recess 405 is provided on the flipping gear 402, and a protrusion 406 adapted to the recess 405 is provided on the flipping limit gear 404. The inner wall of the recess 405 and the outer wall of the protrusion 406 are frictionally engaged, and when a torque is manually applied to the mounting plate 300, the protrusion 406 is adapted to rotate relative to the recess 405 through the turning shaft 1.

[0043] In this embodiment, the flipping driving member 401 is fixed inside the housing 200. The flipping driving member 401 is used to provide power for the relative movement of the mounting plate 300 with respect to the housing 200. The output end of the flipping driving member 401 is connected to a first gear set 403, and the first gear set 403 is connected to a flipping gear 402. The flipping driving member 401 transmits power to the flipping gear 402 through the first gear set 403, enabling the flipping gear 402 to rotate about the second axis. The flipping gear 402 and the flipping limit gear 404 are coaxially arranged and frictionally engaged, enabling the flipping gear 402 to drive the flipping limit gear 404 to rotate about the second axis.

[0044] In this embodiment, a recess 405 on the flipping gear 402 and a protrusion 406 on the flipping limit gear 404 cooperate to form a clutch structure. The recess 405 is a groove recessed in the end face of the flipping gear 402 close to the flipping limit gear 404, and the protrusion 406 is a bump protruding from the flipping limit gear 404 close to the flipping gear 402. A friction engagement surface is directly formed by the geometric shapes of the recess 405 and the protrusion 406, and the recess 405 and the protrusion 406 are respectively integrated into the bodies of the flipping gear 402 and the flipping limit gear 404, which does not require additional axial space and makes the structure inside the housing 200 more compact.

[0045] Among them, the flipping limit gear 404 is in limiting sliding fit with the flipping shaft 1, that is, the flipping limit gear 404 can slide along the extending direction of the flipping shaft 1 and cannot rotate relative to the flipping shaft 1.

[0046] In a specific embodiment, a plurality of limiting protrusions are protruding provided on the outer wall of the flipping shaft 1, and a plurality of limiting grooves adapted to the limiting protrusions are provided on the inner wall of the flipping limit gear 404. In this way, by the cooperation of the limiting protrusions and the limiting grooves, the flipping limit gear 404 can slide along the flipping shaft 1 and cannot rotate relative to the flipping shaft 1.

[0047] It can be understood that when the flipping driving member 401 is used to drive the mounting plate 300 to move relative to the housing 200, the static friction force generated by the engagement surface of the recess 405 and the protrusion 406 is greater than the load torque of the mounting plate 300, enabling the flipping gear 402 and the flipping limit gear 404 to rotate synchronously. The driving force of the flipping driving member 401 sequentially passes through the flipping gear 402, the flipping limit gear 404, and the flipping shaft 1 to drive the mounting plate 300 to rotate about the second axis.

[0048] In another usage mode, when an external torque is applied to the mounting plate 300, the mounting plate 300 transfers the force to the turning shaft 1. The turning shaft 1 has a tendency to drive the turning limit gear 404 to rotate under the cooperation of the limit protrusion and the limit groove. If the load torque exceeds the static friction torque threshold generated by the joint surface of the recessed portion 405 and the protruding portion 406, the turning shaft 1 drives the turning limit gear 404 to rotate relative to the turning gear 402, enabling the protruding portion 406 to slide relative to the recessed portion 405, realizing the manual turning angle adjustment of the rear-view device, and protecting the joint of the turning gear 402 and the first gear set 403 at the same time, avoiding mechanical damage to the turning drive assembly 400.

[0049] Further, a circuit board 2 is fixed inside the housing 200. The turning drive member 401 is preferably set as a motor or a servo motor, and the turning drive member 401 is fixed on the surface of the circuit board 2.

[0050] Optionally, referring to Figure 5 , the turning drive assembly 400 further includes a first fixing seat 407, which is arranged on the side of the turning limit gear 404 away from the turning gear 402, and the first fixing seat 407 is fixed to the turning shaft 1; a first elastic member 408, which is arranged between the first fixing seat 407 and the turning limit gear 404, and the first elastic member 408 is used to press the protruding portion 406 into the recessed portion 405.

[0051] In this embodiment, the first fixing seat 407 is fixed to the turning shaft 1, and the first fixing seat 407 moves synchronously with the turning shaft 1. A first elastic member 408 is arranged between the first fixing seat 407 and the turning limit gear 404. The first elastic member 408 is preferably set as a spring sleeved on the turning shaft 1. In this way, the first elastic member 408 applies a force to the turning limit gear 404, enabling the protruding portion 406 on the turning limit gear 404 to engage with the recessed portion 405 on the turning gear 402, preventing the separation of the protruding portion 406 and the recessed portion 405.

[0052] Specifically, a turning seat 205 is fixed on the housing 200, and the turning shaft 1 passes through the turning seat 205. The turning seat 205 is used to support the turning shaft 1, enabling the turning shaft 1 to rotate relative to the housing 200. A protruding mounting base 301 is arranged on the mounting plate 300, and the mounting base 301 is fixed to the turning shaft 1 through bolts.

[0053] Optionally, referring to Figure 5 , the wall surface where the protruding portion 406 engages with the recessed portion 405 is set as an inclined surface. When a torque is manually applied to the mounting plate 300, the protruding portion 406 can slide along the inclined surface so that the protruding portion 406 can cross the inclined surface.

[0054] In this embodiment, the protruding portion 406 is arranged as a toothed structure, and its side wall is arranged as an inclined surface. The inner wall surface of the recessed portion 405 is adapted to the outer wall surface of the protruding portion 406, and the same inclined surface is adopted. In this way, the joint surface between the protruding portion 406 and the recessed portion 405 is arranged as an inclined surface, which facilitates the joint of the protruding portion 406 and the recessed portion 405. Moreover, when manually operating the mounting plate 300 to reset, the protruding portion 406 can be positioned by the recessed portion 405, which facilitates the mounting plate 300 and the housing 200 to return to the initial mating position.

[0055] Optionally, referring to Figure 4 , the first gear set 403 includes a first flipping worm 4031, a first flipping transmission gear 4032, a first flipping helical gear 4033, a second flipping helical gear 4034, and a second flipping worm 4035. Among them, the first flipping worm 4031 is fixedly connected to the output end of the flipping driving member 401; the first flipping transmission gear 4032 is engaged with the first flipping worm 4031; the first flipping helical gear 4033 is fixedly centered with the first flipping transmission gear 4032; the second flipping helical gear 4034 is engaged with the first flipping helical gear 4033; the second flipping worm 4035 is fixedly centered with the second flipping helical gear 4034, and the second flipping worm 4035 is engaged with the flipping gear 402; a pair of first connecting pieces 4038 are respectively arranged at both ends of the second flipping worm 4035, and the first connecting pieces 4038 are fixedly limited with the housing 200, and the first connecting pieces 4038 are rotationally matched with the second flipping worm 4035.

[0056] In this embodiment, the first flipping worm 4031 and the flipping driving member 401 are fixedly connected with anti-torque. The flipping driving member 401 can drive the first flipping worm 4031 to rotate. A first shaft rod 4036 and a second shaft rod 4037 are rotatably connected to the inner wall of the housing 200. The first shaft rod 4036 passes through the centers of the first flipping transmission gear 4032 and the first flipping helical gear 4033 and is fixed, so that the first flipping transmission gear 4032 and the first flipping helical gear 4033 are coaxially arranged and rotate relative to the housing 200 under the drive of the first flipping worm 4031.

[0057] The second shaft rod 4037 passes through the centers of the second flipping helical gear 4034 and the second flipping worm 4035 and is fixed, so that the second flipping helical gear 4034 and the second flipping worm 4035 are coaxially arranged and rotate relative to the housing 200 under the drive of the first flipping helical gear 4033. The second flipping worm 4035 is engaged with the flipping gear 402, realizing the transmission of the flipping driving member 401 to the flipping gear 402. In this setting, both ends of the second shaft rod 4037 are rotationally matched with the two first connecting pieces 4038 respectively.

[0058] Of course, in addition to the above-described arrangement where the second shaft rod 4037 passes through the second reversing helical gear 4034 and the second reversing worm 4035, the rod portion of the second reversing worm 4035 may also form the second shaft rod 4037, such that the second reversing helical gear 4034 passes through the second reversing worm 4035. And when the rod portion of the second reversing worm 4035 can also form the second shaft rod 4037, a pair of first connecting pieces 4038 are connected to both ends of the second shaft rod 4037. In this way, the second reversing worm 4035 is supported and limited by the pair of first connecting pieces 4038, and when the housing 200 rotates relative to the main body 100 about the first axis, the above-described first gear set 403 can be driven to rotate synchronously.

[0059] Optionally, referring to Figure 3 , Figure 4 , Figure 5 , a reversing potentiometer 600 is provided in the housing 200. A first reversing detection gear 409 is coaxially fixed on the reversing shaft 1. The reversing potentiometer 600 includes: a reversing potentiometer body 601; a reversing detection shaft 602, at least part of which is disposed outside the reversing potentiometer body 601. A second reversing detection gear 603 is coaxially fixedly connected to the end of the reversing detection shaft 602 disposed outside the reversing potentiometer body 601. Among them, the first reversing detection gear 409 and the second reversing detection gear 603 are engaged.

[0060] In this embodiment, the first reversing detection gear 409 and the reversing shaft 1 are coaxially arranged, that is, the first reversing detection gear 409 is fixed to the outer wall of the reversing shaft 1 and can rotate synchronously with the reversing shaft 1. The reversing potentiometer body 601 is fixed to the surface of the circuit board 2. It has a reversing detection shaft 602 that can rotate relative to the reversing potentiometer body 601. A second reversing detection gear 603 is provided on the reversing detection shaft 602, and the first reversing detection gear 409 and the second reversing detection gear 603 are meshed.

[0061] In this way, when the reversing driving member 401 drives the reversing limit gear 404 to rotate, the reversing shaft 1 is driven to rotate by the reversing limit gear 404, and then the first reversing detection gear 409 on the reversing shaft 1 is driven to rotate. Also, when a torque is manually applied to the mounting plate 300, the reversing shaft 1 is driven to rotate, and then the first reversing detection gear 409 on the reversing shaft 1 is driven to rotate.

[0062] With the above-mentioned setting method, compared with the existing setting method of using a PCB carbon film and a spring brush to feedback the position, in this application, the carbon film and the spring brush are encapsulated in the flip potentiometer body 601. Through the direct transmission of the first flip detection gear 409 and the flip shaft 1, the change in the circumferential angle of the flip of the mounting plate 300 is fed back as the circumferential angle change of the flip potentiometer 600 through the flip shaft 1, making the signal transmission purer, avoiding the lag or jump error of the spring brush contact, and improving the detection accuracy of the rotation angle of the mounting plate 300.

[0063] Optionally, referring to Figure 2 , Figure 3 , a connecting shaft 4 is further provided between the housing 200 and the mounting plate 300. The connecting shaft 4 is correspondingly arranged with the flip shaft 1, and the mounting plate 300 is rotatably connected to the housing 200 through the flip shaft 1 and the connecting shaft 4.

[0064] In this embodiment, the flip shaft 1 passes through the flip seat 205, and a flip gear 402, a flip limit gear 404, a first elastic member 408 and a first fixing seat 407 are arranged on the flip shaft 1. A connecting seat 206 is further arranged on the housing 200. The connecting shaft 4 passes through the connecting seat 206 and the mounting plate 300. By using the cooperation of the flip shaft 1 and the connecting shaft 4, the mounting plate 300 is effectively supported, and at the same time, the mounting plate 300 rotates relative to the housing 200 along the second axis.

[0065] Optionally, referring to Figure 6 , the folding drive assembly 500 includes: a folding drive member 501; a folding gear 502 sleeved on the main body 100 and connected to the folding drive member 501 through a second gear set 503; a folding limit gear 504 sleeved on the main body 100 and located below the folding gear 502, and the folding limit gear 504 is adapted to slide relative to the main body 100; wherein, the folding limit gear 504 is frictionally engaged with the folding gear 502, and when a torque is manually applied to the housing 200, the folding gear 502 is adapted to rotate relative to the main body 100.

[0066] In this embodiment, the folding driving member 501 is fixed inside the housing 200. The folding driving member 501 is used to provide power for the relative movement of the housing 200 with respect to the main body 100. The output end of the folding driving member 501 is connected to a second gear set 503, and the second gear set 503 is connected to a folding gear 502. The folding driving member 501 transmits power to the folding gear 502 through the second gear set 503, so that the folding driving member 501 and the second gear set 503 can drive the housing 200 to rotate around the first axis. The folding gear 502 and the folding limit gear 504 are coaxially arranged and frictionally engaged. When manually operating to drive the housing 200 to rotate, the folding gear 502 disengages from the folding limit gear 504, enabling the folding gear 502 to rotate relative to the main body 100, and further enabling the folding driving member 501, the second gear set 503, the folding gear 502, and the housing 200 to rotate synchronously around the first axis.

[0067] In this embodiment, the folding gear 502 and the folding limit gear 504 are frictionally engaged. When manually operating the housing 200 to move, since the folding gear 502 and the second gear set 503 rotate synchronously around the first axis, it can avoid damage to the joint between the folding gear 502 and the second gear set 503.

[0068] Optionally, referring to Figure 6 , Figure 7 , the folding drive assembly 500 further includes a second fixing seat 505 and a second elastic member 506. The second fixing seat 505 and the second elastic member 506 are arranged between the second fixing seat 505 and the folding limit gear 504. The folding gear 502 and the folding limit gear 504 are both provided with inclined surfaces for frictional engagement matching, and the second elastic member 506 is used to press the inclined surface on the folding limit gear 504 against the corresponding inclined surface of the folding gear 502.

[0069] In this embodiment, the second fixing seat 505 is installed on the main body 100 and is disposed below the folding limit gear 504. The main body 100 passes through the second fixing seat 505 and the second elastic member 506. The second elastic member 506 is preferably a spring, and the second elastic member 506 is used to squeeze the folding limit gear 504 to fit with the folding gear 502. When manually applying a torque to the housing 200, the inclined surface of the folding gear 502 moves relative to the inclined surface of the folding limit gear 504, causing the second elastic member 506 to be compressed, realizing the rotation of the folding gear 502 relative to the main body 100, thereby protecting the joint between the folding gear 502 and the second gear set 503.

[0070] It can be understood that inclined surfaces for frictional engagement and matching are provided at the mutually approaching ends of the folding gear 502 and the folding limit gear 504. Taking the folding limit gear 504 as an example, the inclined surface is provided with a plurality of first helical teeth arranged circumferentially along the end of the folding limit gear 504, and a plurality of second helical teeth corresponding to the plurality of first helical teeth are provided at the end of the folding gear 502. When the folding driving member 501 drives the housing 200 to rotate, the first helical teeth and the second helical teeth engage, restricting relative movement between the folding limit gear 504 and the folding gear 502. The folding gear 502 is fixed relative to the main body 100, causing the folding driving member 501 and the second gear set 503 to move around the folding gear 502, thereby driving the housing 200 to rotate. When manually driving the housing 200 to rotate, the second gear set 503 and the folding gear 502 engage, and the first helical teeth and the second helical teeth disengage, causing the second gear set 503 to drive the folding gear 502 to rotate relative to the main body 100.

[0071] Alternatively, the inclined surface is provided with a plurality of first helical teeth arranged circumferentially along the end of the folding limit gear 504, and a plurality of mounting grooves corresponding to the plurality of first helical teeth are provided at the end of the folding gear 502. The inner wall of the mounting groove is provided with an inclined surface adapted to the first helical teeth, which can also achieve the clutch function.

[0072] Furthermore, a wear-resistant sheet 3 is provided between the second fixing seat 505 and the inner wall of the housing 200. When the housing 200 rotates relative to the main body 100, the service life of the housing 200 is improved by means of the wear-resistant sheet 3. The wear-resistant sheet 3 is fixed to the second fixing seat 505 or the inner wall of the housing 200.

[0073] Optionally, referring to Figure 6 , the second gear set 503 includes a first folding worm 5031, a first folding transmission gear 5032, a first folding helical gear 5033, a second folding helical gear 5034, and a second folding worm 5035. Among them, the first folding worm 5031 is fixedly connected to the output end of the folding driving member 501; the first folding transmission gear 5032 engages with the first folding worm 5031; the first folding helical gear 5033 is fixedly centered with the first folding transmission gear 5032; the second folding helical gear 5034 engages with the first folding helical gear 5033; the second folding worm 5035 is fixedly centered with the second folding helical gear 5034, and the second folding worm 5035 engages with the folding gear 502; a pair of second connecting pieces 5038 are respectively arranged at both ends of the second folding worm 5035, and the second connecting pieces 5038 are limit-fixed to the housing 200, and the second connecting pieces 5038 are rotationally matched with the second folding worm 5035.

[0074] In this embodiment, the first folding worm 5031 is fixedly connected to the folding driving member 501 in an anti-torque manner. The folding driving member 501 can drive the first folding worm 5031 to rotate. The inner wall of the housing 200 is rotatably connected to a third shaft 5036 and a fourth shaft 5037. The third shaft 5036 passes through the centers of the first folding transmission gear 5032 and the first folding helical gear 5033 and is fixed, so that the first folding transmission gear 5032 and the first folding helical gear 5033 are coaxially arranged and rotate relative to the housing 200 under the drive of the first folding worm 5031. The fourth shaft 5037 passes through the centers of the second folding helical gear 5034 and the second folding worm 5035 and is fixed, so that the second folding helical gear 5034 and the second folding worm 5035 are coaxially arranged and rotate relative to the housing 200 under the drive of the first folding helical gear 5033. The second folding worm 5035 engages with the folding gear 502 to realize the rotation of the second folding worm 5035 around the folding gear 502. In this setting, both ends of the fourth shaft 5037 are rotatably matched with two second connecting pieces 5038 respectively.

[0075] Of course, in addition to the above setting method in which the fourth shaft 5037 passes through the second folding helical gear 5034 and the second folding worm 5035, the rod portion of the second folding worm 5035 can also form the fourth shaft 5037, so that the second folding helical gear 5034 passes through the second folding worm 5035. And when the rod portion of the second folding worm 5035 can also form the fourth shaft 5037, a pair of second connecting pieces 5038 are connected to both ends of the fourth shaft 5037. In this way, the second folding worm 5035 is supported and limited by a pair of second connecting pieces 5038, and when the housing 200 rotates relative to the main body 100 around the first axis, the above-mentioned second gear set 503 can be driven to rotate synchronously.

[0076] Optionally, referring to Figure 6 , a folding potentiometer 700 is arranged in the housing 200. A first folding detection gear 507 is coaxially fixed on the main body 100. The folding potentiometer 700 includes: a folding potentiometer body 701; a folding detection shaft 702, at least part of which is arranged outside the folding potentiometer body 701 and is rotatably matched with the housing 200. A second folding detection gear 703 is coaxially fixedly connected to the end of the folding detection shaft 702 arranged outside the folding potentiometer body 701. Among them, the first folding detection gear 507 and the second folding detection gear 703 are engaged.

[0077] In this embodiment, the first folding detection gear 507 and the folding limit gear 504 are coaxially arranged, that is, the main body 100 passes through the first folding detection gear 507 and is fixed to the first folding detection gear 507. The folding potentiometer 700 is fixed on the surface of the circuit board 2. It has a folding detection shaft 702 that can rotate relative to the folding potentiometer body 701. A plug post 204 is fixed on the housing 200. The plug post 204 passes through one end of the folding detection shaft 702 and is rotationally matched with the folding detection shaft 702. A second folding detection gear 703 is arranged on the folding detection shaft 702, and the first folding detection gear 507 meshes with the second folding detection gear 703.

[0078] In this way, when the folding driving member 501 works, through the cooperation of the second gear set 503 and the folding gear 502, the housing 200, the folding driving member 501 and the second gear set 503 rotate around the folding gear 502, and when a torque is manually applied to the housing 200 to rotate, and when the housing 200, the folding driving member 501, the second gear set 503 and the folding gear 502 rotate around the main body 100, the rotation of the housing 200 drives the folding potentiometer 700 to rotate. The second folding detection gear 703 of the folding potentiometer 700 is always engaged with the first folding detection gear 507. The first folding detection gear 507 is used to support the second folding detection gear 703, and the plug post 204 is used to support the folding detection shaft 702. The second folding detection gear 703 rotates following the rotation of the housing 200.

[0079] With the above setting method, compared with the existing setting method of using a PCB carbon film and a spring brush to feedback the position, through the direct meshing transmission of the first folding detection gear 507 and the second folding detection gear 703, the change in the folding circumferential angle of the housing 200 is fed back as the change in the circumferential angle of the folding potentiometer 700, making the signal transmission cleaner, avoiding the lag or jump error of the spring brush contact, and improving the detection accuracy of the rotation angle of the housing 200.

A convex bowl-shaped bearing part 203 is formed on the surface of the base 202 close to the vehicle body; wherein, the bowl-shaped bearing part 203 forms a nested fit with the mounting end of the rearview mirror housing through its convex curved surface, and the center of the bowl-shaped bearing part 203 is arranged on the second axis.

[0081] In this embodiment, the upper cover 201 and the base 202 cooperate to form the housing 200, and the mounting plate 300 is separately connected to the upper cover 201, making the overall structure simple and facilitating the installation of the rearview mirror.

[0082] Optionally, referring to Figure 3 , Figure 4 , a circuit board 2 is fixedly arranged inside the housing 200, the main body 100 passes through the circuit board 2, and the circuit board 2 is communicatively connected to the folding drive assembly 500 and the flipping drive assembly 400.

[0083] In this embodiment, the circuit board 2 is used to control the folding drive assembly 500 and the flipping drive assembly 400 to work, so as to realize the rotation of the housing 200 around the first axis and the rotation of the mounting plate 300 around the second axis.
