Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and more particularly to an electronic exterior rearview mirror assembly and a vehicle. Background Technology

[0002] In modern automotive design, exterior rearview mirrors are one of the most important components for ensuring driving safety. Traditional exterior rearview mirrors typically use a fixed mirror design, and the driver adjusts the mirror angle manually or electrically to obtain the best rear visibility.

[0003] Existing electronic side mirrors typically only allow rotational adjustment around the lens axis, resulting in a large motion envelope. In practical use, this design may cause inconvenience and safety hazards. First, when parking, the distance between the vehicle and obstacles is usually small, and the protruding part of the side mirror may restrict parking space, increasing the difficulty of parking. Furthermore, when the driver opens the door to get in or out, the protruding design of the side mirror is prone to collision with surrounding obstacles, causing damage to the mirror or affecting the normal opening of the door. Utility Model Content

[0004] In view of this, this application provides an electronic exterior rearview mirror assembly and a vehicle. The rearview mirror module is rotated around a first axis under the driving action of a first driving device and folded along the vehicle height direction with the mounting component. The motion envelope trajectory of the electronic exterior rearview mirror assembly when it is folded and stored is small, which is convenient for users to park and get in and out of the vehicle.

[0005] In a first aspect, embodiments of this application provide an electronic exterior rearview mirror assembly, comprising: a mounting base, including: a base body and a mounting member, the base body being connected to a vehicle body, and the mounting member being connected to the base body; a rearview mirror module, rotatably connected to the mounting member about a first axis extending along the length direction of the vehicle; and a first driving device disposed on the mounting member and drivingly connected to the rearview mirror module to drive the rearview mirror module to rotate relative to the mounting member.

[0006] The electronic exterior rearview mirror assembly of this application, when the rearview mirror is folded and stored, the rearview mirror module rotates around the first axis under the driving action of the first driving device. That is, the protruding part of the electronic exterior rearview mirror assembly along the left and right direction of the vehicle rotates and the mounting part folds along the height direction of the vehicle. The volume of the protruding part of the electronic exterior rearview mirror assembly along the left and right direction of the vehicle is reduced, and the motion envelope trajectory of the electronic exterior rearview mirror assembly when it is folded and stored is small, which makes it convenient for users to park and get in and out of the vehicle.

[0007] In some embodiments, the rearview mirror module includes: a mirror housing, the mirror housing and the mounting member being rotatably connected; a lens, the lens being disposed on the mirror housing and used to acquire road condition images; and a first driving device for driving the mirror housing to rotate relative to the mounting member.

[0008] The first drive mechanism rotates the mirror housing of the rearview mirror module, allowing users to fold and retract the module when needed, reducing its lateral space occupation and facilitating entry and exit from the vehicle in confined spaces. Simultaneously, the user can adjust the viewing angle of the rearview mirror module via the first drive mechanism to ensure optimal rear visibility for the driver, thus improving vehicle safety.

[0009] According to some embodiments of this application, the mirror housing includes a first end facing the vehicle body along the vehicle width direction, the first end having a pivot shaft extending along the first axis, the mounting member having a first connecting arm extending towards the mirror housing along the vehicle width direction, the first connecting arm having a pivot hole, and the pivot shaft passing through the pivot hole to allow the mirror housing and the mounting member to be rotatably engaged.

[0010] The pivot shaft and pivot hole design provide a stable yet flexible rotational connection, allowing the mirror housing to be rotated and adjusted relative to the mounting bracket within a certain range. This flexibility ensures that the rearview mirror can adjust its viewing angle according to different driving conditions. This design simplifies the installation process of the mirror housing and mounting bracket, while also facilitating subsequent maintenance and replacement, reducing overall maintenance costs and time.

[0011] According to some embodiments of this application, a gear is provided on the pivot shaft; the first driving device includes a drive motor, which is disposed in the inner cavity of the mounting base and fixedly connected to the mounting component; the drive motor has a rotatable output shaft, on which a transmission gear is provided, and the transmission gear meshes with the gear.

[0012] The gear transmission mechanism allows for precise control of the mirror housing's rotation. By adjusting the motor's speed and direction, the viewing angle of the mirror housing can be finely adjusted to meet the visibility requirements under different driving conditions. The drive motor can be integrated with the vehicle's electronic control system to achieve automated and intelligent mirror adjustment. This integration improves the user experience and provides greater ease of operation.

[0013] According to some embodiments of this application, the output shaft is perpendicular to the pivot shaft, and both the gear component and the transmission gear are bevel gears.

[0014] Because bevel gears can transmit power between vertical axes, this design offers greater flexibility, allowing the drive motor to be installed in different orientations and positions, optimizing component layout and space utilization. The bevel gear transmission system allows for precise control of the mirror housing's rotation, meeting the need for fine-tuning the viewing angle under various driving conditions.

[0015] According to some embodiments of this application, the mounting member has a first arc surface formed on one side wall facing away from the rearview mirror module along the vehicle width direction; the mirror housing includes an upper mirror housing and a lower mirror housing, the upper mirror housing and the mounting member are disposed opposite each other along the vehicle width direction, the upper mirror housing has a field of view hole, the lens is disposed inside the upper mirror housing, the pivot shaft is disposed on the upper mirror housing, and the lower mirror housing has a second arc surface formed on one side facing the mounting member along the vehicle width direction; at least a portion of the inner wall of the mounting base is formed as a first arc surface that rotatably engages with the first arc surface, and at least a portion of the outer wall of the mounting base is formed as a second arc surface that rotatably engages with the second arc surface.

[0016] In this way, by matching the first arc surface with the first arc-shaped surface and the second arc surface with the second arc-shaped surface, the mounting component and the mirror housing can achieve smooth rotational movement, reducing friction and mechanical wear between the mounting component and the mirror housing, which helps to extend the service life of the electronic exterior rearview mirror.

[0017] In some embodiments, the lens includes: a first lens disposed on the rear side of the mirror housing along the length direction of the vehicle; and a second lens disposed on the end of the mirror housing away from the vehicle body along the width direction of the vehicle, wherein the angle of view of the second lens is greater than that of the first lens.

[0018] This provides users with environmental images from multiple perspectives, making driving easier.

[0019] In some embodiments, the seat defines a mounting cavity having an opening on one side along the vehicle height direction; the mounting seat further includes a mounting bracket fixed within the mounting cavity, the mounting bracket having a rotating shaft extending along the second axis; the mounting member rotatably covers the opening about the rotating shaft.

[0020] The mounting bracket provides a robust support structure, ensuring the stability of the rotating shaft and the mounting component during rotation. As the mounting component rotates around the rotating shaft, the rearview mirror module and other structures connected to the mounting component rotate, fold, or unfold together.

[0021] According to some embodiments of this application, the second driving device includes: an elastic driving member, which is sleeved on the rotating shaft, one end of which is fixedly connected to the mounting bracket and the other end of which is fixedly connected to the mounting member, and the elastic driving member exerts a force on the mounting member to cause the mounting member to rotate circumferentially about the second axis; or, according to some embodiments of this application, the second driving device further includes: a rotary motor, which is fixed to the base and drivenly connected to the mounting member, and the rotary motor is used to drive the mounting member to rotate relative to the base.

[0022] By incorporating an elastic drive component, when an external force causes the mounting component to rotate around the axis of rotation, the elastic drive component is twisted, storing elastic potential energy. When the external force is removed or reduced, the elastic drive component releases the stored elastic potential energy, propelling the mounting component to continue rotating or return to its initial position, making the movement of the mounting component smoother and more controllable.

[0023] By setting a rotary motor to drive the mounting component to rotate, the mounting component can be rotated automatically, eliminating the need for user pushing and facilitating precise control of the rotation angle. This is suitable for scenarios requiring rapid response and high precision.

[0024] Secondly, embodiments of this application also provide a vehicle, including: a vehicle body; the aforementioned electronic exterior rearview mirror assembly, wherein a mounting bracket for the electronic exterior rearview mirror assembly is fixed to the vehicle body.

[0025] The vehicle described in this application uses the aforementioned electronic exterior rearview mirror assembly, which allows the user to drive the rearview mirror module to rotate around the first axis via the first drive device. This reduces the amount of the electronic exterior rearview mirror protruding along the width of the vehicle, making it easier for the user to park and get in and out of the vehicle in relatively narrow spaces, and reducing the likelihood of the electronic exterior rearview mirror rubbing against the wall.

[0046] In existing technology, electronic exterior rearview mirrors typically only rotate around their lens axis for adjustment, resulting in a large motion envelope. In practical use, this design may cause inconvenience and safety hazards. First, when parking, the distance between the vehicle and obstacles is usually small, and the protruding part of the exterior rearview mirror may restrict parking space, increasing the difficulty of parking. Furthermore, when the driver opens the door to get in or out, the protruding design of the exterior rearview mirror is prone to collisions with surrounding obstacles, causing damage to the mirror or affecting the normal opening of the door.

[0047] For ease of explanation and understanding, please refer to... Figure 1 The vehicle's height direction can be Figure 1 As shown in the Z direction, the length direction of the vehicle can be... Figure 1 As shown in the Y direction, the width direction of the vehicle can be... Figure 1The X direction is shown. In existing rearview mirrors, when stored, the protruding part along the X direction rotates relative to the axis extending along the Z direction, enclosing a large space, which is not convenient for folding and storing the rearview mirror in narrow spaces.

[0048] In view of this, the present application provides an electronic exterior rearview mirror assembly and a vehicle. The rearview mirror module is rotated around a first axis under the driving action of a first driving device and folded along the vehicle height direction with the mounting component. This makes the motion envelope trajectory of the electronic exterior rearview mirror assembly small when it is folded and stored, which is convenient for users to park and get in and out of the vehicle.

[0049] refer to Figures 1-8 In a first aspect, embodiments of this application provide an electronic exterior rearview mirror assembly 100, which may include: a mounting base 110, a rearview mirror module 120, and a first driving device 140.

[0050] Mounting base 110 may include a base body 111 and a mounting member 112. The base body 111 is used to connect to the vehicle body. Exemplarily, the base body 111 can be snapped and fixed to the vehicle body by a clip, or the base body 111 can also be connected to the vehicle body by fasteners such as screws and bolts, providing a stable structural foundation for the electronic exterior rearview mirror assembly 100. The mounting member 112 is connected to the base body 111, and the mounting member 112 can provide a mounting base for the rearview mirror module 120 and the first drive device 140.

[0051] The rearview mirror module 120 is rotatably connected to the mounting member 112 around a first axis 102 extending along the length of the vehicle. In the prior art, the folding of the exterior rearview mirror generally involves rotating the mirror around an axis extending in the Z direction. This results in a large enveloping space for the end of the rearview mirror in the X direction, which is far from the vehicle body, during the rotation and folding process, making folding inconvenient. The rearview mirror module 120 of this application can rotate around the first axis 102 extending in the Y direction, causing the protruding part of the electronic exterior rearview mirror assembly 100 in the X direction (rearview mirror module 120) to flip to the Z direction and fold with the mounting member 112. This reduces the volume occupied by the electronic exterior rearview mirror assembly 100 in the X direction, which is beneficial for the folding of the electronic exterior rearview mirror assembly 100 in narrow spaces.

[0052] A first drive unit 140 is disposed on the mounting member 112 and connected to the rearview mirror module 120 to drive the rearview mirror module 120 to rotate relative to the mounting member 112. Exemplarily, the power output shaft of the first drive unit 140 may coincide with the first axis 102, and the rearview mirror module 120 may be disposed on the power output shaft of the first drive unit 140. The power output shaft of the first drive unit 140 grips a computer, driving the rearview mirror module 120 to rotate relative to the mounting member 112.

[0053] When the electronic exterior rearview mirror assembly 100 of this application is folded and stored, the rearview mirror module 120 is rotated around the first axis 102 under the driving action of the first driving device 140. That is to say, the protruding part of the electronic exterior rearview mirror assembly 100 along the left and right direction of the vehicle is rotated and folded along the height direction of the vehicle with the mounting part 112. The volume of the protruding part of the electronic exterior rearview mirror assembly 100 along the left and right direction of the vehicle is reduced, so that the motion envelope trajectory of the electronic exterior rearview mirror assembly 100 when it is folded and stored is small, which makes it convenient for users to park and get in and out of the vehicle.

[0054] In some embodiments, the mounting member 112 is rotatably connected to the seat 111 about a second axis 101 extending along the vehicle height direction. In other words, the mounting member 112 can rotate about the second axis 101 extending along the Z direction, so that the electronic exterior rearview mirror assembly 100 is folded and stored in the vehicle body. The rotatable connection between the mounting member 112 and the seat 111 can be achieved by defining a circular cavity structure on the seat 111 and rotatably disposing the mounting member 112 within the cavity structure, or by rotatably disposing a rotating shaft 114 on the seat 111 and connecting the rotating shaft 114 to the mounting member 112, thereby realizing the rotatable connection between the mounting member 112 and the seat 111.

[0055] Understandably, when the mounting component 112 and the base 111 are rotatably connected by the rotating shaft 114, the axis of the rotating shaft 114 can coincide with the second axis 101, or the axis of the rotating shaft 114 can be offset from the second axis 101. In this case, the electronic exterior rearview mirror can be unfolded and folded by the deflection between the mounting component 112 and the base 111.

[0056] The second drive device 130 is disposed on the base 111 and connected to the mounting member 112 to drive the mounting member 112 to rotate relative to the base 111. For example, the second drive device 130 can be a drive motor 141. A drive gear can be provided on the power output shaft of the second drive device 130, and a gear ring can be provided on the mounting member 112. The drive gear meshes with the gear ring, and the second drive device 130 drives the mounting member 112 to rotate relative to the base 111 through the meshing of the drive gear and the gear ring. Alternatively, when the mounting member 112 and the base 111 are connected by a rotating shaft 114, the power output shaft of the second drive device 130 can drive the mounting member 112 and the rotating shaft 114 to rotate together through belt drive, chain drive, or gear drive.

[0057] Thus, by cooperating with the rotation of the mounting component 112 around the second axis and the rotation of the rearview mirror module 120 around the first axis, the volume of the protruding part of the electronic exterior rearview mirror assembly 100 along the left and right directions of the vehicle is reduced, resulting in a smaller motion envelope trajectory when the electronic exterior rearview mirror assembly 100 is folded and stored, making it convenient for users to park and get in and out of the vehicle.

[0058] refer to Figure 4 and Figure 5 In some embodiments, the seat 111 defines a mounting cavity 1111, which has an opening on one side along the vehicle height direction. The mounting seat 110 may also include a mounting bracket 113, which is fixed within the mounting cavity 1111. The mounting bracket 113 has a rotating shaft 114 extending along the second axis 101. The mounting member 112 rotatably covers the opening around the rotating shaft 114, protecting the components within the seat 111 from dust, moisture, and other environmental factors, thereby extending the service life of the electronic exterior rearview mirror assembly 100. The rotation of the mounting member 112 can be achieved by a fixed connection between the mounting member 112 and the rotating shaft 114, with the second drive device 130 driving the rotating shaft 114 to rotate via belt drive or gear drive, thereby causing the mounting member 112 to rotate. Alternatively, the mounting member 112 may have a transmission structure such as a gear ring, with the second drive device 130 driving the mounting member 112 to rotate via a drive gear meshing with the gear ring.

[0059] The mounting bracket 113 provides a robust support structure, ensuring that the rotating shaft 114 and the mounting component 112 remain stable during rotation. As the mounting component 112 rotates around the rotating shaft 114, the rearview mirror module 120 and other structures connected to the mounting component 112 rotate, fold, or unfold together.

[0060] refer to Figure 4 and Figure 5 According to some embodiments of this application, the second driving device 130 may include an elastic driving member 131. The elastic driving member 131 is sleeved on the rotating shaft 114. One end of the elastic driving member 131 is fixedly connected to the mounting bracket 113, and the other end is fixedly connected to the mounting member 112. The elastic driving member 131 exerts a force on the mounting member 112, causing the mounting member 112 to rotate about the second axis 101. For example, the elastic driving member 131 may be a rotary spring steel, a torsion spring, etc. Thus, when an external force is applied to the mounting member 112, causing it to rotate relative to the seat 111, the elastic driving member 131 is twisted, storing elastic potential energy. When the external force is removed or reduced, the elastic driving member 131 releases the stored elastic potential energy, pushing the mounting member 112 to continue rotating or return to the initial position, making the movement of the mounting member 112 smoother and more controllable.

[0061] Optionally, in this embodiment, applying external force to the mounting component 112 can be achieved through the rotation motor 132 of the second drive device 130, or, when it is inconvenient for passengers inside the vehicle to adjust, a user outside the vehicle can manually rotate the mounting component 112 to adjust the angle of the electronic exterior rearview mirror assembly 100.

[0062] It should be noted that when the vehicle allows the user to manually rotate the mounting bracket 112, a locking structure can be provided within the mounting cavity 1111 to keep the electronic exterior rearview mirror assembly 100 in the user-set position. For example, the locking structure can be a resilient latch and a locking strip. The locking strip is fixedly disposed within the mounting cavity 1111, and the resilient latch is fixedly connected to the resilient drive member 131. When the resilient drive member 131 rotates with the mounting bracket 112 to the user-set position, the resilient latch engages with the corresponding teeth within the locking strip, thus locking the mounting bracket 112. When the position of the mounting bracket 112 needs to be adjusted, simply apply force to disengage the resilient latch from the locking strip.

[0063] refer to Figure 5 In other embodiments, the second driving device 130 may further include a rotary motor 132, which is fixed to the base 111 and drivenly connected to the mounting member 112. The rotary motor 132 drives the mounting member 112 to rotate relative to the base 111. Exemplarily, the output shaft of the rotary motor 132 may be fixedly connected to a rotating shaft 114 via a coupling, and the rotating shaft 114 may be fixedly connected to the mounting member 112 to drive the mounting member 112 to rotate relative to the base 111. Alternatively, the output shaft of the rotary motor 132 may also be connected to the rotating shaft 114 via belt drive or gear drive, and the rotating shaft 114 may be fixedly connected to the mounting member 112. Alternatively, the output shaft of the rotary motor 132 may be provided with a drive gear, and the mounting member 112 may have a gear ring facing into the mounting cavity 1111. The drive gear meshes with the gear ring to drive the mounting member 112 to rotate relative to the base 111. By setting the rotary motor 132 to drive the mounting component 112 to rotate, it is beneficial to accurately control the rotation angle of the mounting component 112, which is suitable for scenarios that require fast response and high precision.

[0064] refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the rearview mirror module 120 may include a mirror housing 121 and a lens 122.

[0065] The mirror housing 121 is the external structure of the rearview mirror module 120, providing protection for the internal components. The mirror housing 121 is rotatably connected to the mounting member 112, allowing it to rotate relative to the mounting member 112. For example, the mirror housing 121 and the mounting member 112 can be rotatably connected by two links spaced apart along the y-direction, both links being rotatable about a first axis 102, thus allowing the mirror housing 121 to rotate relative to the mounting member 112. Alternatively, a pivot shaft 123 can be provided between the mirror housing 121 and the mounting member 112, with the axis of the pivot shaft 123 coinciding with the first axis 102. Both the mirror housing 121 and the mounting member 112 are rotatably connected to the pivot shaft 123 via connecting arms, allowing the mirror housing 121 to rotate relative to the mounting member 112.

[0066] The lens 122 is disposed on the mirror housing 121 and is used to acquire road condition images. For example, the lens 122 can be disposed on the surface of the mirror housing 121 facing the rear of the vehicle along the Y direction to collect road conditions around the vehicle, reduce blind spots, and improve driving safety.

[0067] Optionally, lens 122 may include an electronic camera; of course, lens 122 may also include a conventional reflector.

[0068] The first driving device 140 is used to drive the mirror housing 121 to rotate relative to the mounting member 112. For example, the first driving device 140 can be directly connected to the mirror housing 121 through a structure such as a linkage mechanism, and drive the mirror housing 121 to rotate relative to the mounting member 112 through the driving linkage structure. Alternatively, the mirror housing 121 can be fixedly connected to the pivot shaft 123 located on the first axis 102, and the first driving device 140 drives the pivot shaft 123 to rotate through gear transmission or belt transmission, so that the mirror housing 121 rotates relative to the mounting member 112.

[0069] The first drive device 140 drives the mirror housing 121 of the rearview mirror module 120 to rotate, which allows the user to fold and retract the rearview mirror module 120 when needed, reducing the space occupied by the vehicle in the lateral direction and making it easier for the user to get in and out of the vehicle in narrow spaces. At the same time, the user can also adjust the viewing angle of the rearview mirror module 120 through the first drive device 140 to ensure that the driver has the best rear view, which helps to improve the driving safety of the vehicle.

[0070] In some embodiments, lens 122 may include a first lens and a second lens. The first lens is located at the rear of the mirror housing 121 along the length of the vehicle, and the second lens is located at the end of the mirror housing 121 away from the vehicle body along the width of the vehicle. The second lens has a wider field of view than the first lens. For example, the first lens can be an ultra-wide-angle lens with a focal length of 13mm-24mm and a field of view of 60°-120°. The first lens is used as a side-view or rear-view camera to monitor blind spots and assist in lane changing or parking. The second lens can be a fisheye lens, used in a surround-view system to provide a panoramic view with a field of view of not less than 180 degrees. The second lens can also be used for close-range environmental perception, such as automatic parking or low-speed driving. This provides the user with environmental images from multiple perspectives, facilitating driving.

[0071] refer to Figure 3 and Figure 4 According to some embodiments of this application, the mirror housing 121 may include a first end 121a extending towards the vehicle body in the vehicle width direction. The first end 121a is provided with a pivot shaft 123 extending along a first axis 102. The mounting member 112 has a first connecting arm 1121 extending towards the mirror housing 121 in the vehicle width direction. The first connecting arm 1121 is provided with a pivot hole, and the pivot shaft 123 passes through the pivot hole, so that the mirror housing 121 and the mounting member 112 are rotatably engaged. The design of the pivot shaft 123 and the pivot hole provides a stable and flexible rotational connection, allowing the mirror housing 121 to be rotated and adjusted relative to the mounting member 112 within a certain range. This flexibility ensures that the rearview mirror can adjust the viewing angle according to different driving conditions. This design simplifies the installation process of the mirror housing 121 and the mounting member 112, and also facilitates later maintenance and replacement, reducing overall maintenance costs and time.

[0072] Furthermore, multiple first connecting arms 1121 can be provided, and the pivot shaft 123 rotates through multiple pivot holes on the first connecting arms 1121, which helps to improve the connection stability between the mirror housing 121 and the mounting part 112, thereby improving the reliability of the rearview mirror module 120 rotating around the first axis 102.

[0073] refer to Figure 1 Figure 2 , Figure 3 and Figure 4 According to some embodiments of this application, a gear 124 may be provided on the pivot shaft 123; the first driving device 140 includes a drive motor 141, which is located in the inner cavity of the mounting base 110 and is fixedly connected to the mounting member 112; the drive motor 141 has a rotatable output shaft, on which a transmission gear 1411 is provided, and the transmission gear 1411 meshes with the gear 124.

[0074] The gear transmission mechanism allows for precise control of the rotation of the mirror housing 121. By adjusting the speed and direction of the motor, the viewing angle of the mirror housing 121 can be finely adjusted to meet the visibility requirements under different driving conditions. The drive motor 141 can be integrated with the vehicle's electronic control system to achieve automated and intelligent mirror adjustment. This integration improves the user experience and provides greater ease of operation.

[0075] Optionally, in this embodiment, both the gear component 124 and the transmission gear 1411 can be spur gears. In this case, the output shaft and the pivot shaft 123 are arranged in parallel. Alternatively, both the gear component 124 and the transmission gear 1411 can be bevel gears. In this case, the output shaft and the pivot shaft 123 can be arranged relatively perpendicularly.

[0076] refer to Figure 3 According to some embodiments of this application, the output shaft is perpendicular to the pivot shaft 123, and both the gear component 124 and the transmission gear 1411 are bevel gears. Since bevel gears can transmit power between vertical shafts, this design provides greater flexibility, allowing the drive motor 141 to be installed in different orientations and positions, optimizing component layout and space utilization. The bevel gear transmission system allows for precise control of the rotation of the mirror housing 121, meeting the need for fine adjustment of the viewing angle under different driving conditions.

[0077] refer to Figure 4 and Figure 5 According to some embodiments of this application, the side wall of the mounting member 112 facing away from the rearview mirror module 120 along the vehicle width direction is formed as a first arcuate surface 1122, and at least a portion of the inner wall of the mounting base 110 is formed as a first arcuate surface 115 that rotatably engages with the first arcuate surface 1122. Exemplarily, a portion of the surface of the mounting base 110 opposite to the mounting member 112 may be recessed in a direction away from the mounting member 112 (towards the vehicle interior along the X direction) to engage with the first arcuate surface 1122. The first arc-shaped surface 115, or the surface of the mounting base 110 facing the mounting member 112, is recessed in the direction away from the mounting member 112 (towards the inside of the vehicle in the X direction) to form the first arc-shaped surface 115. When the mounting member 112 rotates, at least a portion of the surfaces between the first arc-shaped surface 1122 and the first arc-shaped surface 115 slide and fit together, so that the arc-shaped surface and the first arc-shaped surface 115 rotate and cooperate without interference, which helps to extend the service life of the electronic exterior rearview mirror assembly 100.

[0078] The mirror housing 121 may include an upper mirror housing 1211 and a lower mirror housing 1212. The upper mirror housing 1211 and the mounting member 112 are arranged opposite to each other along the width direction (X direction) of the vehicle. The upper mirror housing 1211 is provided with a field of view hole. The lens 122 is located inside the upper mirror housing 1211. The upper mirror housing 1211 and the lower mirror housing 1212 can be fixedly connected by a snap-fit, so that the mirror housing 121 forms an integral structure.

[0079] The pivot shaft 123 can be provided on the upper lens housing 1211 so that the first drive device 140 can drive the upper lens housing 1211 and the lower lens housing 1212 to rotate together.

[0080] The lower mirror housing 1212 is formed as a second arcuate surface 1212a on the side facing the mounting member 112 along the vehicle width direction (X direction). At least a portion of the structure of the outer wall of the mounting base 110 is formed as a second arcuate surface 116 that rotatably engages with the second arcuate surface 1212a. For example, a portion of the structure of the surface of the mounting base 110 facing the mirror housing 121 may protrude toward the lower mirror housing 1212 to form the second arcuate surface 116. Alternatively, the surface of the mounting base 110 facing the mirror housing 121 may protrude toward the lower mirror housing 1212 to form the second arcuate surface 116. The surface of the mounting base 110 facing the mirror housing 121 may be the surface of the mounting cavity 1111 facing the mirror housing 121 along the X direction. The second arcuate surface 116 slidably fits against at least a portion of the surface of the second arcuate surface 1212a.

[0081] Thus, by cooperating with the second arc surface 1212a and the second arc surface 116, the mirror housing 121 will not experience dryness between itself and the mounting base 110 when it rotates, which helps to extend the service life of the electronic exterior rearview mirror assembly 100.

[0082] Furthermore, by setting the values ​​of the curvature radii of the first arc surface 1122 and the second arc surface 1212a, the contact area between the lower mirror housing 1212 and the mounting part 112 and the base 111 can be adjusted, thereby reducing the wear of the electronic exterior rearview mirror assembly 100 and extending the service life of the electronic exterior rearview mirror.

[0083] Secondly, embodiments of this application also provide a vehicle, which may include a vehicle body and the aforementioned electronic exterior rearview mirror assembly 100, wherein the mounting base 110 of the electronic exterior rearview mirror assembly 100 is fixed to the vehicle body.

[0084] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0085] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0086] In the vehicle described in this application, the use of the aforementioned electronic exterior rearview mirror assembly 100 allows the user to drive the rearview mirror module 120 to rotate around the first axis 102 via the first drive device 140, thereby reducing the amount of protrusion of the electronic exterior rearview mirror along the width direction of the vehicle. This is beneficial for the user to park and get in and out of the vehicle in relatively narrow spaces, and reduces the likelihood of the electronic exterior rearview mirror rubbing against the wall.

[0087] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
