[0040] An embodiment of the present application provides a folder that can be installed in a vehicle rearview mirror assembly. The folder housing can be connected to the rearview mirror assembly's outer shell, thereby driving the rearview mirror housing to rotate, allowing the rearview mirror assembly to switch between a folded and unfolded state. When the rearview mirror assembly is in the folded state, the risk of scratches on the rearview mirror when parking or navigating narrow roads is reduced. When the rearview mirror assembly is in the unfolded state, the driver's field of view is expanded to obtain more information about the vehicle's exterior. Furthermore, if the folder is equipped with a motor, the folder can also be electrically rotated.

[0041] Reference Figures 1 to 4 , shows a schematic structural diagram of the folder described in the embodiment of the present application. Figures 1 to 4 As shown, the folder may include: a shell 20, a base shaft 30 and a driving mechanism, wherein the shell 20 is used to connect with the rearview mirror housing, a accommodating cavity is provided in the shell 20, one end of the base shaft 30 is fixedly connected to the vehicle body, a through hole is provided in the center of the shell 20, and the other end of the base shaft 30 passes through the through hole of the shell 20 so that the base shaft 30 can be connected to the vehicle body, the base 40, shell 20, driving mechanism and other structures of the folder can be sleeved on the base shaft 30 and connected into one, the driving mechanism is provided in the accommodating cavity and movably connected to the shell 20; when the driving mechanism drives the shell 20 to rotate around the base shaft 30, the shell 20 can drive the rearview mirror housing to rotate synchronously to realize the switching of the rearview mirror assembly between the folded state and the unfolded state.

[0042] In actual applications, the rearview mirror serves as a visual auxiliary component of the vehicle, providing convenience for the driver to observe the external field of view. However, since the rearview mirror housing has a certain volume, the angle of rotation of the rearview mirror housing around the base axis 30 needs to be limited within a certain range to prevent the rearview mirror housing from rotating excessively and colliding with the vehicle door, causing damage.

[0043] In the embodiment of the present application, the housing 20 is provided with a first limiting portion 221, and the drive mechanism is provided with a second limiting portion extending toward the housing 20 to engage with the first limiting portion 221. The drive mechanism is used to drive the housing 20 to rotate about the base axis 30, thereby driving the first limiting portion 221 to rotate within a first rotation plane, thereby switching the folder between a first state and a second state. In the first state, the first limiting portion 221 abuts the second limiting portion, and the rearview mirror housing is in the unfolded state. In the second state, the first limiting portion 221 releases the abutment with the second limiting portion, and the rearview mirror housing is in the folded state.

[0044] Specifically, a first stop 221 is provided on the inner wall of the housing 20, and a second stop extends toward the housing 20 and is at least partially abuttable against the first stop 221. When the drive mechanism drives the housing 20 to rotate about the base axis 30 until the first stop 221 on the housing 20 abuts and is restrained by the second stop, the folder reaches its ultimate deployed position, thereby limiting the rotation of the housing 20. In actual use, the rearview mirror assembly completes its final rotation from the parking position to the driving position, reaching its ultimate deployed position.

[0045] In an embodiment of the present application, the shell 20 includes a side plate 222 and a bottom plate 223, the side plate 222 is connected to the bottom plate 223 to enclose a accommodating cavity, wherein the first limiting portion 221 is connected to the inner side wall of the side plate, and the first rotation plane is perpendicular to the axial direction of the base shaft 30 and is arranged parallel to the bottom plate 223.

[0046] Specifically, the housing 20 includes a lower housing 22 and an upper housing 21. The lower housing 22 includes mutually perpendicular side panels 222 and a bottom panel 223. The bottom panel 223 is annular and has a central through-hole. The side panels 222 are cylindrical and connected to the bottom panel 223 to form a housing. The base shaft 30 passes through the central through-hole of the bottom panel 223. One end of the base shaft 30 extends through the central through-hole to the exterior of the housing 20 for connection to the vehicle body. The portion of the base shaft 30 within the housing 20 is used to support the drive mechanism. The bottom panel 223 is perpendicular to the axial direction of the base shaft 30, and the first rotational plane is parallel to the bottom panel 223.

[0047] The shell 20 also includes an upper shell 21. A positioning structure that cooperates with the center hole of the base shaft 30 is provided at a position corresponding to the center hole of the base shaft 30. The centering structure can be a positioning protrusion facing the base shaft. When the upper shell 21 and the lower shell 22 are matched, the positioning protrusion can cooperate with the center hole of the base shaft 30 to ensure the verticality of the base shaft 30 relative to the horizontal plane and the rigidity of the entire folder.

[0048] In actual application, since the first limiting portion 221 of the shell 20 rotates in the first rotation plane, and the first rotation plane is parallel to the bottom plate 223, in addition, the second limiting portion of the limiting ring 135 is configured to maintain contact with the bottom plate 223 of the shell during rotation. Therefore, the second limiting portion will not collide with the bottom plate 223 during rotation, thereby avoiding the relative movement of the second limiting portion and the first limiting portion 221 along the height direction of the shell 20, thereby avoiding the second limiting portion from colliding with the shell 20 after passing the first limiting portion 221, and reducing the noise generated by the folding of the rearview mirror.

[0049] In an embodiment of the present application, the first limiting portion 221 includes a guide surface and a limiting surface, the guide surface and the limiting surface are connected to the inner wall of the side plate 222, the guide surface and the limiting surface are both perpendicular to the first rotation plane and are set at a preset angle; the second limiting portion can slide relatively along the guide surface from the side away from the limiting surface to the side close to the limiting surface, and abut against the limiting surface.

[0050] Specifically, if Figure 9 As shown, the guide surface is set at a preset angle with the side plate 222 of the shell 20, and the limiting surface is set at a roughly right angle with the side plate 222 of the shell 20, so that the second limiting portion can slide relatively along the guide surface from the side away from the limiting surface to the side close to the limiting surface, and abut against the limiting surface.

[0051] It should be noted that, in the prior art, the guide surface of the limit block of the shell 20 is set at a preset angle to the bottom plate 223. Therefore, the limit ring 135 needs to generate a climbing motion along the guide surface to the top of the guide surface. During the continued rotation, the limit ring 135 leaves the guide surface and rebounds downward, colliding with the bottom plate 223 of the shell 20, which is likely to generate loud noise. Compared with this structure in the prior art, the structure of the first limit part 221 in the embodiment of the present application avoids the mutual collision between the second limit part and the bottom plate 223, thereby reducing the noise of the folder during rotation.

[0052] In some embodiments of the present application, the second limiting portion includes a compression portion 1351 and an abutment portion 1352 , wherein the compression portion 1351 is connected to the driving mechanism, and the abutment portion 1352 is connected to the compression portion 1351 and abuts against the first limiting portion 221 .

[0053] Specifically, refer to Figure 9 、 Figure 10 The compression portion 1351 is connected to the limiting ring 135 in the drive mechanism at both ends, and the abutment portion 1352 is connected to the middle of the compression portion 1351. The middle section of the compression portion 1351 is also spaced apart from the limiting ring 135 to provide better deformation conditions. The abutment portion 1352 extends toward the housing 20 and can abut against the first limiting portion 221. Under certain operating conditions, when the housing 20 and the limiting ring 135 rotate relative to each other, the abutment portion 1352 can abut against the first limiting portion 221 of the housing 20.

[0054] Furthermore, the compression portion 1351 is a flexible member and can be elastically deformed along the radial direction of the base shaft 30 .

[0055] It can be understood that since the compression part 1351 is a flexible part and can undergo elastic deformation along the radial direction of the base shaft 30, the second limiting part of the limiting ring 135 can be smoother when it rotates relative to the guide surface of the first limiting part 221 of the shell 20, avoiding the rotational jamming between the shell 20 and the limiting ring 135 due to the greater rigidity of the second limiting part; at the same time, after the second limiting part passes over the guide surface of the first limiting part 221, it can rebound to the abutment part 1352 under the action of elastic force and abut against the limiting surface of the first limiting part 221.

[0056] In the embodiment of the present application, the shell 20 includes a plurality of first limiting portions 221 , which are evenly spaced along the inner wall of the shell 20 , and the number of the second limiting portions matches the number of the first limiting portions 221 .

[0057] It can be understood that since the shell 20 includes multiple first limiting portions 221, and the multiple first limiting portions 221 are evenly spaced along the inner wall of the shell 20, when the limiting cooperation between one of the first limiting portions 221 and the second limiting portion fails, the remaining first limiting portions 221 and the second limiting portions can continue to function, thereby ensuring the limiting effect of the limiting ring 135 on the shell 20.

[0058] In the embodiment of the present application, the driving mechanism includes a driving component and an output component. The driving component is connected to the output component. The output component is rotatably connected to the base shaft 30 and is engaged with the housing 20. The second limiting portion is provided on the output component.

[0059] Specifically, the drive assembly includes a motor 11, a first worm 121, a first bevel gear 122, a second worm 123, and a second bevel gear 124. The output shaft of the motor 11 is fixedly connected to the first worm 121 and drives the first worm 121 to rotate. The first worm 121 meshes with the first bevel gear 122, and the second worm 123 is fixedly connected to the first bevel gear 122, and the second worm 123 meshes with the second bevel gear 124. Under the action of the motor 11, the second bevel gear 124 can ultimately be driven to rotate. The drive assembly also includes a control board, which is connected to the lower housing 22 to provide power to the folder and provide overload protection for the motor 11 in the event of a stall.

[0060] Furthermore, the second bevel gear 124 is connected to the output assembly. The rotation of the second bevel gear 124 can drive the output assembly to rotate around the base shaft 30 . Since the housing 20 is engaged with the output assembly, the rotation of the output assembly can drive the housing 20 to rotate around the base shaft 30 .

[0061] like Figure 4 As shown, in the embodiment of the present application, the folder is provided with a first retaining spring 131, a spring 132, a spring sleeve 133, a second bevel gear 124, a connecting ring 134, a limiting ring 135, a lower shell 22, a second retaining spring 136, and a base 40 from top to bottom. The above components are all sleeved on the outside of the base shaft 30. The first retaining spring 131 is partially limited by the riveting of the base shaft 30, so that the first retaining spring 131 cannot move upward. The first retaining spring 131 also presses down the spring 132, the spring 132 presses down the spring sleeve 133, and the spring sleeve 133 presses down the second bevel gear 124. The second bevel gear 124 presses down the connecting ring 134, the limiting ring 135 and the base 40 through the bone position, and the limiting ring 135 presses down the lower shell 22. Furthermore, the base shaft 30 also passes through the base 40 and is axially limited by the second retaining spring 136. The second retaining spring 136 cooperates with the corresponding retaining groove on the base shaft 30 through overpressure. The elastic force generated by the elastic deformation of the second retaining spring 136 presses the base 40 downward, and the base 40 is clamped and fixed by the second retaining spring 136 and the base shaft 30. In actual application, the base shaft 30 and the base 40 are relatively fixed to the frame.

[0062] In the embodiment of the present application, the folder separately makes the web portion of the second bevel gear 124 into a wear-resistant metal part, namely the spring sleeve 133 in the embodiment of the present application, and at the same time replaces the washer at the bottom of the spring 132 to prevent the metal spring 132 from wearing out and shortening the life of the folder when it rotates relative to the plastic.

[0063] In addition, the base 40 includes an inner ring and an outer ring, wherein the inner ring is located in the accommodating cavity, and the inner ring bone position can be engaged with the second bevel gear 124; the outer ring is located at the bottom of the lower shell 22, and the outer ring bone position can be engaged with the bottom of the lower shell 22.

[0064] In the embodiment of the present application, the output assembly includes a limiting ring 135 , which is sleeved on the base shaft 30 and coaxially arranged with the base shaft 30 . The second limiting portion is arranged on the limiting ring 135 and extends radially toward the housing 20 along the limiting ring 135 .

[0065] Furthermore, the output assembly also includes a connecting ring 134, which is sleeved between the base shaft 30 and the limiting ring 135, and is coaxially arranged with the base shaft 30 and the limiting ring 135; a limiting protrusion 1241 is provided at the bottom of the driving assembly, and a first limiting groove 1353 that cooperates with the limiting protrusion 1241 is provided at the top of the limiting ring 135, and a second limiting groove that cooperates with the limiting protrusion 1241 is provided at the top of the connecting ring 134. When the limiting protrusion 1241 is engaged with the first limiting groove 1353 and the second limiting groove, the driving assembly can drive the shell 20 to rotate.

[0066] Specifically, if Figure 11 As shown, a limiting protrusion 1241 is provided at the bottom of the second bevel gear 124. Figure 10 As shown, the top of the limiting ring 135 is provided with a limiting groove 1353 that cooperates with the limiting protrusion 1241. In addition, the top of the connecting ring 134 is provided with a second limiting groove (not shown in the figure) that cooperates with the limiting protrusion 1241. When the limiting protrusion 1241 is engaged with the first limiting groove 1353 and the second limiting groove, the second bevel gear 124 is kept relatively stationary with the limiting ring 135, the base 40, and the connecting ring 134 through the above limiting structure, and the base shaft 30 and the base 40 are also kept relatively stationary through the non-smooth circular structure. At this time, the shell 20 rotates relative to the second bevel gear.

[0067] Optionally, when the folder is electrically driven to unfold, the rearview mirror assembly rotates from the parking position to the driving position, and the second bevel gear 124 rotates relative to the base 40 under the drive of the motor 11 until it abuts against the base 40. Under the limiting action of the base 40, the second bevel gear 124 is forced to stop rotating, and then the motor 11 drives the housing 20 and the limit ring 135 to rotate in the opposite direction. When the limit ring 135 partially abuts against the second bevel gear 124, the limit ring 135 is forced to stop rotating, and the housing 20 continues to rotate until it abuts against the second limit portion of the limit ring 135, and the rearview mirror unfolds to the driving position.

[0068] Optionally, the bottom of the second bevel gear 124 further comprises a joint that interlocks with the connecting ring 134 and the inner ring of the base 40. When the folder is electrically driven to fold, the rearview mirror assembly rotates from the driving position to the parking position. The rotation of the second bevel gear 124 drives the connecting ring 134 to rotate. When the second bevel gear 124 and the connecting ring 134 rotate until they interlock with the base 40, the lower housing 22 is driven to rotate relative to it. The bottom of the lower housing 22 and the outer ring of the base 40 have a concave-convex fit. As the lower housing 22 rotates, because the base 40 is fixed to the vehicle frame, the lower housing 22 can be displaced axially upward along the base shaft 30. This displacement is just enough to disengage the lower housing 22 and the base 40.

[0069] In summary, the folder provided by the embodiments of the present application has at least the following beneficial effects:

[0070] In an embodiment of the present application, a folder includes a housing, a base shaft, and a drive mechanism. The base shaft is disposed within the housing and partially extends outside the housing for connection to the vehicle body. The drive mechanism is disposed within the housing and movably connected to the housing, and is configured to drive the housing to rotate about the base shaft. The folder housing can be connected to a rearview mirror housing, and rotation of the housing about the base shaft drives rotation of the rearview mirror housing, thereby achieving the folding function of the rearview mirror assembly. The housing is provided with a first stopper, and the drive mechanism is provided with a second stopper, which extends toward the housing and can engage with the first stopper to limit the rotation of the housing. When the housing rotates about the base shaft, the first stopper rotates within a first rotational plane, preventing relative movement of the second stopper and the first stopper along the height direction of the housing. This prevents the second stopper from colliding with the housing after passing the first stopper, thereby reducing noise generated by folding the rearview mirror, improving product competitiveness, and enhancing user experience.

[0071] The present application also discloses a rearview mirror assembly, including a rearview mirror housing and the above-mentioned folder, wherein the folder housing 20 is connected to the rearview mirror housing, and the driving mechanism drives the housing to rotate, thereby driving the rearview mirror housing to rotate.

[0072] In actual application, the rearview mirror housing is connected to the folder housing 20. When the folder housing 20 rotates relative to the base shaft 30, the rearview mirror housing also rotates synchronously with the rotation of the housing 20, thereby realizing the switching of the rearview mirror between the folded state and the unfolded state.

[0073] The present application also discloses a vehicle comprising the rearview mirror assembly as described above.

[0074] It should be noted that the folder provided in the embodiment of the present application is only an example and is applicable to the left side of the vehicle. Normally, rearview mirrors need to be installed on both sides of the vehicle to ensure the driver's external vision. When the folder is applied to the right side rearview mirror assembly of the vehicle, the structure of the folder can be adjusted accordingly according to the rotation direction of the rearview mirror assembly.

[0075] In addition, the rearview mirror assembly and the vehicle provided in the embodiment of the present application have the same or similar beneficial effects as the above-mentioned folder, which will not be repeated here.
