[0094] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0095] Please refer to Figures 1-8 In a first aspect, an embodiment of the present application provides a folder, including a main body 100 , a shell 200 , a mounting plate 300 , a flip drive assembly 400 and a folding drive assembly 500 .

[0096] Among them, the main body 100 is used to be connected to the vehicle body; the shell 200 has a first end and a second end, at least a part of the main body 100 is passed through the first end of the shell 200, and the shell 200 can rotate around the first axis relative to the main body 100; the mounting plate 300 is arranged at the second end of the shell 200, and a flip axis 1 is provided on the shell 200, and the flip axis 1 and the mounting plate 300 are fixed to each other. The mounting plate 300 is rotatably connected to the shell 200 through the flip axis 1, and can rotate around the second axis relative to the shell 200, and the mounting plate 300 is used to set a rearview mirror.

[0097] Specifically, the first and second axes are preferably arranged perpendicularly. The first axis serves as the folding axis of the vehicle's rearview device, while the second axis serves as the tilting axis of the rearview device. One end of the main body 100 is fixed to the vehicle body, while the other end of the main body 100 is inserted through the first end of the housing 200 and extends into the housing 200. The main body 100 is preferably a cylindrical structure, serving as a central mounting tube and having a hollow interior for routing wires.

[0098] The central axis of the main body 100 is configured as a first axis, enabling the housing 200 to rotate about the central axis of the main body 100 to complete the folding action of the rear-view device. The mounting plate 300 is rotatably connected to the housing 200 via the flip axis 1. With the central axis of the flip axis 1 serving as a second axis, the mounting plate 300 can rotate with the flip axis 1, achieving rotation of the mounting plate 300 about the central axis of the flip axis 1 to complete the flipping action of the rear-view device.

[0099] Among them, the flipping drive assembly 400 and the folding drive assembly 500 are both arranged in the shell 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 shell 200 to rotate around the first axis; wherein, the flipping drive assembly 400 and the folding drive assembly 500 are arranged independently of each other.

[0100] Specifically, an independently operating flip drive assembly 400 and folding drive assembly 500 are arranged in the housing 200. The flip drive assembly 400 and the folding drive assembly 500 are not mechanically coupled, and their layout is reasonable. The flip drive assembly 400 and the folding drive assembly 500 can operate independently, which is suitable for meeting the complex motion scene requirements of rearview equipment. In addition, the independent transmission of the flip drive assembly 400 and the folding drive assembly 500 avoids the accumulation of errors caused by motion interference, ensures the positioning accuracy of each degree of freedom, and does not affect the function of the other drive assembly after a single drive assembly fails. This avoids the mutual influence of the transmission structures of the flip drive assembly 400 and the folding drive assembly 500, thereby improving the reliability and service life of the system.

[0101] Optionally, refer to Figure 3 The flip driving assembly 400 includes a flip driving member 401, a flip gear 402, a first gear set 403 and a flip limiting gear 404, wherein the flip gear 402 is connected to the flip driving member 401 through the first gear set 403; the flip limiting gear 404 is arranged on the side of the flip gear 402 close to the main body 100, the flip limiting gear 404 and the flip gear 402 are both sleeved on the flip shaft 1, and the flip limiting gear 404 is limited and slidably matched with the flip shaft 1; wherein the flip shaft 1 is arranged at one end outside the shell 200 and fixed to the mounting plate 300, a recessed portion 405 is provided on the flip gear 402, and a protrusion 406 adapted to the recessed portion 405 is provided on the flip limiting gear 404, the inner wall of the recessed portion 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 suitable for rotating relative to the recessed portion 405 through the flip shaft 1.

[0102] In this embodiment, the flip driving member 401 is fixed in the shell 200, and the flip driving member 401 is used to provide power for the movement of the mounting plate 300 relative to the shell 200. The output end of the flip driving member 401 is connected to the first gear group 403, and the first gear group 403 is connected to the flip gear 402. The flip driving member 401 transmits power to the flip gear 402 through the first gear group 403, so that the flip gear 402 can rotate around the second axis. The flip gear 402 is coaxially arranged with the flip limit gear 404 and frictionally engaged, so that the flip gear 402 can drive the flip limit gear 404 to rotate around the second axis.

[0103] In this embodiment, the recessed portion 405 on the flip gear 402 and the protruding portion 406 on the flip limiting gear 404 cooperate to form a clutch structure. The recessed portion 405 is a groove recessed into the end surface of the flip gear 402 near the flip limiting gear 404, and the protruding portion 406 is a bump protruding from the flip limiting gear 404 near the flip gear 402. The geometric shapes of the recessed portion 405 and the protruding portion 406 directly form a frictional engagement surface. The recessed portion 405 and the protruding portion 406 are respectively integrated into the flip gear 402 and the flip limiting gear 404 bodies, eliminating the need for additional axial space and making the structure within the housing 200 more compact.

[0104] The flip limiting gear 404 is in limited sliding cooperation with the flip shaft 1 , that is, the flip limiting gear 404 can slide along the extending direction of the flip shaft 1 but cannot rotate relative to the flip shaft 1 .

[0105] In a specific embodiment, the outer wall of the tilt shaft 1 is provided with a plurality of stop protrusions, and the inner wall of the tilt stop gear 404 is provided with a plurality of stop grooves adapted to the stop protrusions. Thus, the stop protrusions and stop grooves cooperate to enable the tilt stop gear 404 to slide along the tilt shaft 1 but not to rotate relative to the tilt shaft 1.

[0106] It can be understood that when the flip driving member 401 is used to drive the mounting plate 300 to move relative to the shell 200, the static friction force generated by the joint surface of the recessed portion 405 and the protruding portion 406 is greater than the load torque of the mounting plate 300, so that the flip gear 402 and the flip limit gear 404 maintain synchronous rotation. The driving force of the flip driving member 401 passes through the flip gear 402, the flip limit gear 404 and the flip shaft 1 in turn, driving the mounting plate 300 to rotate around the second axis.

[0107] In another usage mode, when an external torque is applied to the mounting plate 300, the mounting plate 300 transmits the force to the flip shaft 1. The flip shaft 1 has a tendency to drive the flip limit gear 404 to rotate under the cooperation of the limiting protrusion and the limiting 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 flip shaft 1 drives the flip limit gear 404 to rotate relative to the flip gear 402, so that the protruding portion 406 can slide relative to the recessed portion 405, thereby realizing manual flip angle adjustment of the rearview device, and at the same time protecting the joint between the flip gear 402 and the first gear set 403 to avoid mechanical damage to the flip drive assembly 400.

[0108] Furthermore, a circuit board 2 is fixed in the housing 200 , and the flip driving component 401 is preferably configured as a motor or a servo motor, and the flip driving component 401 is fixed to the surface of the circuit board 2 .

[0109] Optionally, refer to Figure 5The flip drive assembly 400 also includes a first fixed seat 407, which is arranged on the side of the flip limit gear 404 away from the flip gear 402, and the first fixed seat 407 is fixed to the flip axis 1; a first elastic member 408 is arranged between the first fixed seat 407 and the flip limit gear 404, and the first elastic member 408 is used to press the protrusion 406 into the recessed portion 405.

[0110] In this embodiment, the first fixing seat 407 is fixed to the flip shaft 1, and the first fixing seat 407 moves synchronously with the flip shaft 1. A first elastic member 408 is provided between the first fixing seat 407 and the flip limiting gear 404. The first elastic member 408 is preferably a spring sleeved on the flip shaft 1. In this way, the first elastic member 408 applies a force to the flip limiting gear 404, causing the protrusion 406 on the flip limiting gear 404 to engage with the recessed portion 405 on the flip gear 402, thereby preventing the protrusion 406 and recessed portion 405 from separating.

[0111] Specifically, a flip seat 205 is fixed to the housing 200, and the flip shaft 1 is inserted into the flip seat 205. The flip seat 205 supports the flip shaft 1 so that the flip shaft 1 can rotate relative to the housing 200. A protruding mounting base 301 is provided on the mounting plate 300, and the mounting base 301 is fixed to the flip shaft 1 via bolts.

[0112] Optionally, refer to Figure 5 The wall surface where the protrusion 406 and the recessed portion 405 engage is set as an inclined surface. When a torque is manually applied to the mounting plate 300, the protrusion 406 can slide along the inclined surface so that the protrusion 406 passes over the inclined surface.

[0113] In this embodiment, the protrusion 406 is configured as a tooth-shaped structure, with its sidewalls configured as beveled surfaces. The inner wall of the recessed portion 405 is adapted to the outer wall of the protrusion 406, which also utilizes a beveled surface. Thus, the engaging surface between the protrusion 406 and the recessed portion 405 is configured as a beveled surface, facilitating engagement between the protrusion 406 and the recessed portion 405. Furthermore, when manually resetting the mounting plate 300, the recessed portion 405 can be used to position the protrusion 406, facilitating return of the mounting plate 300 and the housing 200 to their initial mating position.

[0114] Optionally, refer to Figure 4The first gear set 403 includes a first flip worm 4031, a first flip transmission gear 4032, a first flip bevel gear 4033, a second flip bevel gear 4034 and a second flip worm 4035, wherein the first flip worm 4031 is fixedly connected to the output end of the flip driving member 401; the first flip transmission gear 4032 and the first flip worm 4031 are engaged; the first flip bevel gear 4033 and the first flip transmission gear 4032 are fixed in the center; the second flip bevel gear 4034 and the first flip bevel gear 4033 are engaged; the second flip worm 4035 and the second flip bevel gear 4034 are fixed in the center, and the second flip worm 4035 and the flip gear 402 are engaged; a pair of first connecting pieces 4038 are respectively provided at both ends of the second flip worm 4035, the first connecting piece 4038 and the shell 200 are limited and fixed, and the first connecting piece 4038 rotates in cooperation with the second flip worm 4035.

[0115] In this embodiment, the first flip worm 4031 and the flip driving member 401 are fixedly connected to resist torque, and the flip driving member 401 can drive the first flip worm 4031 to rotate. The inner wall of the shell 200 is rotatably connected with the first shaft 4036 and the second shaft 4037. The first shaft 4036 is passed through the center of the first flip transmission gear 4032 and the first flip bevel gear 4033 and is fixed, so that the first flip transmission gear 4032 and the first flip bevel gear 4033 are coaxially arranged and rotate relative to the shell 200 under the drive of the first flip worm 4031.

[0116] The second shaft 4037 is passed through the center of the second flip bevel gear 4034 and the second flip worm 4035 and is fixed, so that the second flip bevel gear 4034 and the second flip worm 4035 are coaxially arranged and rotate relative to the shell 200 under the drive of the first flip bevel gear 4033. The second flip worm 4035 and the flip gear 402 are engaged to realize the transmission of the flip driving member 401 to the flip gear 402. Under this arrangement, the two ends of the second shaft 4037 are respectively rotated with the two first connecting pieces 4038.

[0117] Of course, in addition to the aforementioned arrangement in which the second shaft 4037 is inserted through the second flip bevel gear 4034 and the second flip worm 4035, the body of the second flip worm 4035 can also form the second shaft 4037, so that the second flip bevel gear 4034 is inserted through the second flip worm 4035. Furthermore, when the body of the second flip worm 4035 also forms the second shaft 4037, a pair of first connecting pieces 4038 are connected to the ends of the second shaft 4037. In this way, the pair of first connecting pieces 4038 support and limit the second flip worm 4035, and when the housing 200 rotates relative to the main body 100 about the first axis, the first gear set 403 can be driven to rotate synchronously.

[0118] Optionally, refer to Figure 3 、 Figure 4 、 Figure 5 A flip potentiometer 600 is provided in the housing 200, and a first flip detection gear 409 is coaxially fixed on the flip shaft 1. The flip potentiometer 600 includes: a flip potentiometer body 601; a flip detection shaft 602, at least partially arranged outside the flip potentiometer body 601, and the flip detection shaft 602 is arranged on the end outside the flip potentiometer body 601 and is coaxially fixedly connected to a second flip detection gear 603; wherein the first flip detection gear 409 and the second flip detection gear 603 are engaged.

[0119] In this embodiment, the first flip detection gear 409 is coaxially arranged with the flip shaft 1, that is, the first flip detection gear 409 is fixed to the outer wall of the flip shaft 1 and can rotate synchronously with the flip shaft 1. The flip potentiometer body 601 is fixed to the surface of the circuit board 2, which has a flip detection shaft 602 that can rotate relative to the flip potentiometer body 601. The second flip detection gear 603 is provided on the flip detection shaft 602, and the first flip detection gear 409 and the second flip detection gear 603 are engaged.

[0120] In this way, when the flip driving member 401 drives the flip limit gear 404 to rotate, the flip limit gear 404 is used to drive the flip shaft 1 to rotate, and then drive the first flip detection gear 409 on the flip shaft 1 to rotate; and when the torque is manually applied to the mounting plate 300, the flip shaft 1 is driven to rotate, and then the first flip detection gear 409 on the flip shaft 1 is driven to rotate.

[0121] Adopting the above-mentioned setting method, compared with the existing setting method of PCB carbon film combined with spring brush feedback position, the present application encapsulates the carbon film and the spring brush into the flip potentiometer body 601, and directly transmits the first flip detection gear 409 and the flip shaft 1, and feeds back the flip circular angle change of the mounting plate 300 through the flip shaft 1 as the circular angle change of the flip potentiometer 600, so that the signal transmission is purer, the lag or jump error of the spring brush contact is avoided, and the detection accuracy of the rotation angle of the mounting plate 300 is improved.

[0122] Optionally, refer 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 provided corresponding to the flip shaft 1 . The mounting plate 300 is rotatably connected to the housing 200 through the flip shaft 1 and the connecting shaft 4 .

[0123] In this embodiment, the flip shaft 1 is inserted through the flip seat 205 and is provided with a flip gear 402, a flip limit gear 404, a first elastic member 408, and a first fixed seat 407. The housing 200 is also provided with a connecting seat 206. The connecting shaft 4 is inserted through the connecting seat 206 and the mounting plate 300. The flip shaft 1 and the connecting shaft 4 cooperate to effectively support the mounting plate 300 and enable the mounting plate 300 to rotate relative to the housing 200 along the second axis.

[0124] Optionally, refer to Figure 6 The folding drive assembly 500 includes: a folding drive member 501; a folding gear 502, which is 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, which is sleeved on the main body 100 and located below the folding gear 502, and the folding limit gear 504 is suitable for sliding 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 shell 200, the folding gear 502 is suitable for rotating relative to the main body 100.

[0125] In this embodiment, the folding drive member 501 is fixed in the shell 200, and the folding drive member 501 is used to provide power for the shell 200 to move relative to the main body 100. The output end of the folding drive member 501 is connected to the second gear group 503, and the second gear group 503 is connected to the folding gear 502. The folding drive member 501 transmits power to the folding gear 502 through the second gear group 503, so that the folding drive member 501 and the second gear group 503 can drive the shell 200 to rotate around the first axis. The folding gear 502 is coaxially arranged with the folding limit gear 504 and frictionally engaged. When the shell 200 is manually driven to rotate, the folding gear 502 is disengaged from the folding limit gear 504, so that the folding gear 502 can rotate relative to the main body 100, thereby causing the folding drive member 501, the second gear group 503, the folding gear 502 and the shell 200 to rotate synchronously around the first axis.

[0126] In this embodiment, the folding gear 502 and the folding limit gear 504 are frictionally engaged. When the manually operated shell 200 moves, the folding gear 502 and the second gear group 503 rotate synchronously around the first axis, which can avoid damage to the joint between the folding gear 502 and the second gear group 503.

[0127] Optionally, refer to Figure 6 、 Figure 7The folding drive assembly 500 also includes a second fixed seat 505 and a second elastic member 506, wherein the second fixed seat 505 and the second elastic member 506 are arranged between the second fixed seat 505 and the folding limit gear 504; wherein the folding gear 502 and the folding limit gear 504 are both provided with inclined portions for frictional engagement and matching, and the second elastic member 506 is used to press the inclined portion on the folding limit gear 504 onto the corresponding inclined portion of the folding gear 502.

The main body 100 is penetrated by the second fixing seat 505 and the second elastic member 506. The second elastic member 506 is preferably a spring, which is used to squeeze the folding limit gear 504 until it is in contact with the folding gear 502. When a torque is manually applied to the housing 200, the inclined portion of the folding gear 502 moves relative to the inclined portion of the folding limit gear 504, compressing the second elastic member 506 and enabling the folding gear 502 to rotate relative to the main body 100, thereby protecting the joint between the folding gear 502 and the second gear assembly 503.

[0129] It is understood that the ends of the folding gear 502 and the folding limit gear 504 that are close to each other are both provided with inclined portions for frictional engagement and matching. Taking the folding limit gear 504 as an example, the inclined portion is configured as 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 drive 501 drives the housing 200 to rotate, the first helical teeth and the second helical teeth engage, limiting the relative movement of 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 drive 501 and the second gear set 503 to move around the folding gear 502, thereby driving the housing 200 to rotate. When the housing 200 is manually driven to rotate, the second gear set 503 engages with the folding gear 502, and the first and second helical teeth disengage, causing the second gear set 503 to drive the folding gear 502 to rotate relative to the main body 100.

[0130] Alternatively, the inclined portion is configured as a plurality of first bevel teeth arranged circumferentially along the end of the folding limit gear 504, and a plurality of mounting grooves corresponding to the plurality of first bevel teeth are provided at the end of the folding gear 502, and the inner wall of the mounting groove is configured as an inclined surface adapted to the first bevel teeth, which can also realize the clutch function.

[0131] Furthermore, a wear-resistant plate 3 is provided between the second fixed seat 505 and the inner wall of the shell 200. When the shell 200 rotates relative to the main body 100, the wear-resistant plate 3 is used to improve the service life of the shell 200. The wear-resistant plate 3 is fixed to the second fixed seat 505 or the inner wall of the shell 200.

[0132] Optionally, refer to Figure 6 The second gear group 503 includes a first folding worm 5031, a first folding transmission gear 5032, a first folding bevel gear 5033, a second folding bevel gear 5034 and a second folding worm 5035, wherein the first folding worm 5031 is fixedly connected to the output end of the folding drive member 501; the first folding transmission gear 5032 is engaged with the first folding worm 5031; the first folding bevel gear 5033 is fixed at the center of the first folding transmission gear 5032; the second folding bevel gear 5034 is engaged with the first folding bevel gear 5033; the second folding worm 5035 and the second folding bevel gear 5034 are fixed at the center, and the second folding worm 5035 is engaged with the folding gear 502; a pair of second connecting pieces 5038 are respectively arranged at both ends of the second folding worm 5035, the second connecting piece 5038 is fixed to the shell 200, and the second connecting piece 5038 rotates in cooperation with the second folding worm 5035.

[0133] In this embodiment, the first folding worm 5031 and the folding drive member 501 are fixedly connected to each other in an anti-torque manner. The folding drive member 501 can drive the first folding worm 5031 to rotate. The inner wall of the shell 200 is rotatably connected to the third shaft 5036 and the fourth shaft 5037. The third shaft 5036 is passed through the center of the first folding transmission gear 5032 and the first folding bevel gear 5033 and is fixed, so that the first folding transmission gear 5032 and the first folding bevel gear 5033 are coaxially arranged and are relatively rotated under the drive of the first folding worm 5031. The shell 200 rotates, and the fourth shaft rod 5037 is passed through the center of the second folding bevel gear 5034 and the second folding worm gear 5035 and is fixed, so that the second folding bevel gear 5034 and the second folding worm gear 5035 are coaxially arranged and rotate relative to the shell 200 under the drive of the first folding bevel gear 5033. The second folding worm gear 5035 and the folding gear 502 are engaged to realize the rotation of the second folding worm gear 5035 around the folding gear 502. Under this arrangement, the two ends of the fourth shaft rod 5037 are respectively rotated with the two second connecting pieces 5038.

Furthermore, when the body portion of the second folding worm 5035 also forms 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 pair of second connecting pieces 5038 support and limit the second folding worm 5035, and when the housing 200 rotates relative to the main body 100 about the first axis, the second gear set 503 can be driven to rotate synchronously.

The fold detection shaft 702 is provided with a second fold detection gear 703, and the first fold detection gear 507 and the second fold detection gear 703 are meshed.

[0137] In this way, when the folding drive member 501 is working, the second gear group 503 and the folding gear 502 cooperate with each other, and the shell 200, the folding drive member 501 and the second gear group 503 rotate around the folding gear 502, and when the torque is manually applied to the shell 200 to rotate, the shell 200, the folding drive member 501, the second gear group 503 and the folding gear 502 rotate around the main body 100, and the rotation of the shell 200 drives the folding potentiometer 700 to rotate, and the second folding detection gear 703 of the folding potentiometer 700 is always engaged with the first folding detection gear 507, and the first folding detection gear 507 is used to support the second folding detection gear 703, and the column 204 is used to support the folding detection shaft 702, and when the shell 200 rotates, the second folding detection gear 703 follows the rotation.
