Description

TECHNICAL FIELD

[0001] The present application relates to the vehicle technical field, specifically to electronic rearview mirror and vehicle. BACKGROUND

[0002] Electronic rearview mirror is a new type of vehicle rearview mirror which uses digital technology to replace traditional optical glass mirror. Compared with traditional vehicle rearview mirror, electronic rearview mirror has wider application and better appearance, and is more and more widely used in vehicles.

[0003] In the related art, the electronic outside rearview mirror includes a camera assembly, a shell and an adjusting mechanism. The camera assembly is used for shooting images. The shell is provided with a camera window. The camera assembly is fixed in the shell and shoots external images through the camera window. The adjusting mechanism is connected with the camera assembly and exposed outside the shell. The adjusting mechanism is used for adjusting the shooting angle of the camera assembly. The adjusting mechanism includes a horizontal adjusting assembly for adjusting the horizontal shooting angle of the camera assembly and a vertical adjusting assembly for adjusting the vertical shooting angle of the camera assembly.

[0004] However, the electronic rearview mirror is usually installed on the outside of the vehicle body. When the vehicle is running, the electronic rearview mirror will contact with the airflow around the vehicle body, thereby causing wind resistance to the vehicle and affecting the energy consumption of the vehicle. CONTENT OF THE UTILITY MODEL

[0005] One of the purposes of the utility model is to provide an electronic rearview mirror to solve the problem that the electronic rearview mirror causes wind resistance to the vehicle and affects the energy consumption of the vehicle. The second purpose of the utility model is to provide a vehicle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] In the first aspect, the present application provides an electronic rearview mirror for a vehicle. The electronic rearview mirror includes a camera, a first shell and a second shell. The camera is used for shooting picture information of the tail of the vehicle. The first shell is used for connecting to the inside of the vehicle body. The camera is connected to the second shell, and the second shell is connected to the first shell and can move along the width direction of the vehicle relative to the first shell, so as to switch the electronic rearview mirror between the working state and the storage state. When the electronic rearview mirror is in the working state, the camera is located on the outside of the vehicle body. When the electronic rearview mirror is in the storage state, the second shell and the camera are both located inside the first shell.

[0008] According to the above technical means, when the driver needs to observe the picture information of the rear side of the vehicle, the electronic rearview mirror can be switched from the storage state to the working state. During the process, the second shell moves relative to the first shell to the outside of the vehicle body to drive the camera to move to the outside of the vehicle body, so as to facilitate the camera to shoot the image information of the rear side of the vehicle, and facilitate the driver to drive the vehicle.

[0009] When the driver does not need to observe the picture information of the rear side of the vehicle, for example, when the vehicle is in an automatic driving state, the electronic rearview mirror can be switched from the working state to the storage state. During the process, the second shell gradually moves into the first shell. At this time, since the second shell is located inside the vehicle body, the entire electronic rearview mirror is located inside the vehicle body. During the driving of the vehicle, the electronic rearview mirror does not contact with the airflow around the vehicle body, so as to reduce the wind resistance and the energy consumption of the vehicle.

[0010] In some embodiments, the electronic rearview mirror further comprises a transmission assembly and a driving member, the transmission assembly is connected with the second shell, and the driving member is connected with the transmission assembly to drive the second shell to move through the transmission assembly.

[0011] According to the above technical means, the cooperation of the driving member and the transmission assembly can facilitate the control of the movement of the second shell relative to the first shell, so as to facilitate the switching of the electronic rearview mirror between the working state and the storage state.

[0012] In some embodiments, the transmission assembly comprises a first transmission member and a second transmission member, the driving member is connected with the first transmission member to drive the first transmission member to rotate relative to the first shell, the second transmission member is in transmission connection with the first transmission member and is connected with the second shell, and the rotation of the first transmission member can drive the second transmission member to move along the width direction of the vehicle.

[0013] According to the above technical means, through the cooperation of the first transmission member and the second transmission member, the rotational motion can be converted into linear motion, which can facilitate the arrangement of the driving member, the first shell and the second shell in space, and save space.

[0014] In some embodiments, one of the first transmission member and the second transmission member comprises a first screw rod, the other of the first transmission member and the second transmission member comprises a first nut, and the first nut is in threaded connection with the first screw rod. And / or, the transmission assembly further comprises a speed reducer connected between the driving member and the first transmission member.

[0015] According to the above technical means, the cooperation structure of the first screw rod and the first nut is relatively simple, easy to realize and easy to operate. Through the arrangement of the speed reducer, the power transmission between the driving member and the first transmission member can be more stable, so that the cooperation between the first transmission member and the second transmission member is more stable, and the switching of the electronic rearview mirror between the working state and the storage state is more stable.

[0016] In some embodiments, the second transmission member is rotationally connected to the second housing about a first axis, and the first axis is in a direction consistent with a width direction of the vehicle; and the rotation of the first transmission member is capable of driving the rotation of the second transmission member about the first axis.

[0017] According to the above technical means, when the first transmission member drives the second transmission member to move in the width direction of the vehicle, and drives the second transmission member to rotate relative to the second housing, the second housing can also move relatively slowly relative to the first housing, so that the second housing moves more stably.

[0018] In some embodiments, the second housing comprises a first sub-housing and a second sub-housing, the first sub-housing is connected to the first housing and connected with the second transmission member; the second sub-housing is connected to the first sub-housing and capable of moving in the width direction of the vehicle relative to the first sub-housing; the camera is connected to the second sub-housing; when the electronic rearview mirror is in the working state, part of the first sub-housing is located outside the first housing, and part of the second sub-housing is located outside the first sub-housing; when the electronic rearview mirror is in the storage state, the first sub-housing is located inside the first housing, and the second sub-housing and the camera are both located inside the first sub-housing.

[0019] According to the above technical means, when the electronic rearview mirror is in the storage state, the electronic rearview mirror can be completely hidden inside the vehicle body to reduce the wind resistance caused by the electronic rearview mirror. Moreover, the space occupied by the electronic rearview mirror in the storage state inside the vehicle body can be reduced, so as to facilitate the arrangement of the electronic rearview mirror inside the vehicle body.

[0020] In some embodiments, the transmission assembly further comprises a third transmission member and a fourth transmission member, the third transmission member is connected to the second transmission member and capable of rotating with the second transmission member; the fourth transmission member is connected to the second sub-housing; one of the third transmission member and the fourth transmission member is provided with an internal thread, and the other of the third transmission member and the fourth transmission member is provided with an external thread, the internal thread and the external thread are screwed; the rotation of the third transmission member is capable of driving the fourth transmission member to move in the width direction of the vehicle.

[0021] According to the above technical means, when the first transmission member drives the second transmission member to rotate, the second transmission member can drive the third transmission member to rotate. Under the cooperation of the internal thread and the external thread, the rotation of the third transmission member is capable of driving the fourth transmission member to move in the width direction of the vehicle, so as to drive the second sub-housing to move in the width direction of the vehicle relative to the first sub-housing. In this way, the cooperation of the first transmission member, the second transmission member, the third transmission member and the fourth transmission member can make the first sub-housing move relative to the first housing, and at the same time, make the second sub-housing move relative to the first sub-housing, only by one driving member, so as to simplify the structure of the electronic rearview mirror, and facilitate the control of the electronic rearview mirror.

[0022] In some embodiments, the fourth transmission member is rotationally connected to the second sub-housing around the first axis, and the third transmission member is rotationally capable of driving the fourth transmission member to rotate around the first axis.

[0023] According to the above technical means, in the process of switching the electronic rearview mirror from the storage state to the working state, if the second sub-housing is blocked by an obstacle and cannot move, if the driving member is still working, the fourth transmission member can be driven to rotate relative to the second sub-housing, so as to avoid the second sub-housing and the fourth transmission member from being damaged due to the failure of rotation between the fourth transmission member and the second sub-housing. Moreover, while the third transmission member drives the fourth transmission member to move in the width direction of the vehicle and drives the fourth transmission member to rotate relative to the second sub-housing, the second sub-housing can also move relatively slowly relative to the first sub-housing, so as to make the movement of the second sub-housing more stable.

[0024] In some embodiments, one of the first housing and the second housing is provided with a groove extending in the width direction of the vehicle, and the other of the first housing and the second housing is provided with a protrusion, at least part of the protrusion being located in the groove and being capable of sliding in the groove.

[0025] According to the above technical means, the groove can limit the position of the protrusion in the circumferential direction, so as to avoid the second housing from rotating when moving relative to the first housing, and to ensure the stability of the movement of the second housing relative to the first housing. Moreover, the groove can also guide the protrusion, so as to guide the second housing when moving relative to the first housing, and to further improve the stability of the movement of the second housing relative to the first housing.

[0026] In some embodiments, the first housing is provided with a first limiting portion and a second limiting portion which are arranged at intervals in the width direction of the vehicle, and the second housing is provided with a third limiting portion which is located between the first limiting portion and the second limiting portion.

[0027] According to the above technical means, when the electronic rearview mirror is switched from the storage state to the working state, the third limiting portion can be in contact with the second limiting portion, so as to limit the third limiting portion by the second limiting portion, thereby avoiding the second housing from completely separating from the first housing, and ensuring the stability of the electronic rearview mirror in the working state. When the electronic rearview mirror is switched from the working state to the storage state, the third limiting portion can be in contact with the first limiting portion, so as to limit the third limiting portion by the first limiting portion, thereby ensuring the stability of the electronic rearview mirror in the storage state.

[0028] In a second aspect, the embodiments of the present application also provide a vehicle, which comprises the electronic rearview mirror described in the first aspect.

[0029] Since the vehicle provided in this application includes the electronic rearview mirror in the first aspect, it can solve the same technical problems as the electronic rearview mirror described above and achieve the same technical effects, it will not be described again here.

[0060] In the description of the present application, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0061] Please refer to Figure 1 , Figure 1A vehicle 1000 provided by an embodiment of the present application is shown in a structure schematic diagram when an electronic rearview mirror is in a working state. The present application provides a vehicle 1000. The vehicle 1000 can be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, a fuel vehicle, etc.

[0062] The vehicle 1000 comprises a vehicle body 100 and an electronic rearview mirror 200. The electronic rearview mirror 200 is connected to the vehicle body 100, and is used to capture picture information of the rear of the vehicle 1000, so as to help the driver obtain picture information of the road condition, pedestrians, vehicles, etc. behind the vehicle 1000, so as to help the driver control the vehicle 1000 and drive safely.

[0063] For example, the electronic rearview mirror 200 is connected to both sides of the vehicle body 100 in the width direction of the vehicle 1000, for example, connected to one side of the front door of the vehicle 1000 facing away from the rear door.

[0064] Please refer to Figure 2 , Figure 2 For Figure 1 The electronic rearview mirror 200 in the vehicle 1000 shown in the structure schematic diagram when in a working state. The electronic rearview mirror 200 comprises a support structure 10 and a camera 20 arranged on the support structure 10. The support structure 10 is connected to the vehicle body 100. The camera 20 faces the rear of the vehicle 1000, and is used to capture picture information of the rear of the vehicle 1000. The picture information captured by the camera 20 is displayed on a liquid crystal display inside the vehicle 1000 after digital vision processing, so that the driver obtains the picture information of the rear of the vehicle 1000 through the picture displayed on the liquid crystal display.

[0065] Compared with the traditional glass lens rearview mirror, the electronic rearview mirror 200 has a wider field of view, a small and streamlined appearance design, can reduce the drag coefficient of the vehicle 1000, reduce wind noise, improve energy economy and in-vehicle quietness, and is an important direction of the development of current rearview mirrors.

[0066] However, with the rapid development of the intelligentization of the vehicle 1000, the necessity of the rearview mirror of the vehicle 1000 is gradually weakening. The city / highway NOA has been mass-produced and landed. For such a vehicle 1000 in an automatic driving driving scene, the rearview mirror is no longer a necessary component. However, it will take a long time for the mass production and landing of L4 and L5 level unmanned vehicles 1000. In this transition stage, it is necessary to design an electronic rearview mirror 200 that can be automatically adjusted according to different driving modes, so as to maximize the benefits of energy economy and in-vehicle quietness.

[0067] The existing retractable electronic rearview mirror 200 is fixed on both sides of the vehicle 1000 in the width direction. The retraction adjustment is to adjust the imaging angle, eliminate blind spots, and ensure driving safety. When the electronic rearview mirror 200 is retracted, it is still located outside the body 100 of the vehicle 1000. During the driving process of the vehicle 1000, the electronic rearview mirror 200 still generates a large amount of wind resistance, which cannot improve energy economy and cabin quietness to the ideal state.

[0068] Therefore, in some embodiments, please refer to [the relevant documentation]. Figure 1 and Figure 2 The support structure 10 includes a first housing 1 and a second housing 2. The first housing 1 is connected to the interior of the vehicle body 100 of the vehicle 1000. That is, the first housing 1 is completely hidden inside the vehicle body 100. For example, the vehicle body 100 is provided with a receiving groove ( Figure 1 (Not shown in the image), the first housing 1 is disposed within the receiving groove. Specifically, along the width direction of the vehicle 1000, the vehicle body 100 has a first side and a second side, and there are two receiving grooves, namely a first receiving groove and a second receiving groove. The first receiving groove is recessed from the first side towards the second side, and the second receiving groove is recessed from the second side towards the first side. The vehicle 1000 includes two electronic rearview mirrors 200. The first housing 1 of one electronic rearview mirror 200 is completely located within the first receiving groove, and the first housing 1 of the other electronic rearview mirror 200 is completely located within the second receiving groove.

[0069] The camera 20 is connected to the second housing 2, which is connected to the first housing 1, and can move relative to the first housing 1 along the width direction of the vehicle 1000 so that the electronic rearview mirror 200 can switch between working state and storage state.

[0070] Please continue reading. Figure 1 and Figure 2 When the electronic rearview mirror 200 is in working condition, the camera 20 is located on the outside of the vehicle body 100.

[0071] Please see Figure 3 and Figure 4 , Figure 3 for Figure 1 The diagram shows the structure of the vehicle 1000 when the electronic rearview mirror 200 is in the retracted state. Figure 4 for Figure 3 The diagram shows the structure of the electronic rearview mirror 200 in the vehicle 1000 when it is in the retracted state. When the electronic rearview mirror 200 is in the retracted state, both the second housing 2 and the camera 20 are located inside the first housing 1. Specifically, both the second housing 2 and the camera 20 are completely hidden inside the first housing 1.

[0072] In this way, when the driver needs to observe the image information of the rear side of the vehicle 1000, the electronic rearview mirror 200 can be switched from the storage state to the working state, and in this process, the second shell 2 moves relative to the first shell 1 to the outside of the vehicle body 100 to drive the camera 20 to move to the outside of the vehicle body 100, thereby facilitating the camera 20 to shoot the image information of the rear side of the vehicle 1000, and facilitating the driver to drive the vehicle 1000.

[0073] When the driver does not need to observe the image information of the rear side of the vehicle 1000, for example, when the vehicle 1000 is in an automatic driving state, the electronic rearview mirror 200 can be switched from the working state to the storage state, and in this process, the second shell 2 gradually moves to the inside of the first shell 1. At this time, since the second shell 2 is located inside the vehicle body 100, the entire electronic rearview mirror 200 is located inside the vehicle body 100. During the driving of the vehicle 1000, the electronic rearview mirror 200 does not contact the airflow around the vehicle body 100, thereby reducing the wind resistance and the energy consumption of the vehicle 1000, and improving the energy economy and the quietness inside the vehicle 1000 to a more ideal state.

[0074] Among them, the adjustment of the electronic rearview mirror 200 can be manually adjusted, automatically adjusted or combined with AI adaptive adjustment according to different scenes.

[0075] In some embodiments, the number of cameras 20 can be one or more. For example, the number of cameras 20 can be 2, 3, 4, etc. Among them, in order to reduce the wire harness design, the camera 20 can adopt a wireless transmission imaging camera 20 such as Bluetooth.

[0076] In some embodiments, the opening of the accommodating groove can also be provided with a cabin door that can automatically slide. When the electronic rearview mirror 200 is in the storage state, the cabin door closes the opening of the accommodating groove to block the electronic rearview mirror 200 in the accommodating groove.

[0077] In some embodiments, please continue to refer to Figure 2 and Figure 4 , the electronic rearview mirror 200 further comprises a transmission assembly 3 and a driving piece 4. The transmission assembly 3 is connected with the second shell 2. The driving piece 4 is connected with the transmission assembly 3 to drive the second shell 2 to move through the transmission assembly 3.

[0078] Through the cooperation of the driving piece 4 and the transmission assembly 3, the movement of the second shell 2 relative to the first shell 1 can be conveniently controlled, thereby facilitating the switching of the electronic rearview mirror 200 between the working state and the storage state.

[0079] In some examples, the drive component 4 can be a motor, an electric actuator, etc. This application uses a motor as an example to illustrate the use of the drive component 4. The motor can be a servo motor or other motor capable of precise control, thus achieving the purpose of precise control.

[0080] The motor can be software-controlled and integrated with the vehicle's control software. When the car enters a city / highway NOA (Noise, Air, and Ocean) zone, the motor is activated to automatically retract the electronic rearview mirrors (200° side mirrors) to a stowed state, reducing wind resistance and thus energy consumption. Meanwhile, a manual control switch is retained and integrated into the steering wheel, center console, and other internal components of the vehicle.

[0081] In some embodiments, please refer to Figure 5 , Figure 5 for Figure 2 The diagram shows a cross-sectional view of the electronic rearview mirror 200. The transmission assembly 3 includes a first transmission member 31 and a second transmission member 32. The drive member 4 is connected to the first transmission member 31 and is used to drive the first transmission member 31 to rotate relative to the first housing 1. The second transmission member 32 is connected to the first transmission member 31 and is also connected to the second housing 2. Rotation of the first transmission member 31 can drive the second transmission member 32 to move along the width direction of the vehicle 1000.

[0082] In this way, the drive component 4 can drive the first transmission component 31 to rotate, thereby causing the first transmission component 31 to drive the second transmission component 32 to move along the width direction of the vehicle 1000. This allows the second transmission component 32 to drive the second housing 2 to move relative to the first housing 1 along the width direction of the vehicle 1000, thus switching the electronic rearview mirror 200 between its working and retracted states. In this way, by converting rotational motion into linear motion through the first transmission component 31 and the second transmission component 32, the drive component 4, the first housing 1, and the second housing 2 can be arranged in space more conveniently, saving space.

[0083] In some embodiments, please continue reading Figure 5 One of the first transmission component 31 and the second transmission component 32 includes a first screw 311, and the other of the first transmission component 31 and the second transmission component 32 includes a first nut 321, which is threadedly connected to the first screw 311. The axial direction of the first screw 311 is aligned with the width direction of the vehicle 1000.

[0084] In this way, the rotation of the first transmission component 31 can drive the second transmission component 32 to move along the axial direction of the first screw 311 (i.e., the width direction of the vehicle 1000), thereby enabling the electronic rearview mirror 200 to switch between the working state and the storage state. The structure of the first screw 311 and the first nut 321 is relatively simple, easy to implement and easy to operate.

[0085] The present application is exemplarily described with the first transmission member 31 being a first screw 311 and the second transmission member 32 being a first nut 321.

[0086] In some embodiments, the transmission assembly 3 further comprises a speed reducer 33 connected between the driving member 4 and the first transmission member 31. The driving member 4 transmits power to the first transmission member 31 through the speed reducer 33, so that the first transmission member 31 drives the second transmission member 32 to move along the width direction of the vehicle 1000. The power transmission between the driving member 4 and the first transmission member 31 is more stable through the arrangement of the speed reducer 33, so that the cooperation between the first transmission member 31 and the second transmission member 32 is more stable, and the electronic rearview mirror 200 is more stable in switching between the working state and the storage state.

[0087] In some embodiments, please refer to Figure 5 , the speed reducer 33 comprises a speed reducer box 331 fixed to the vehicle body 100 and arranged in the vehicle body 100. Specifically, the speed reducer box 331 is arranged in the accommodating groove on the vehicle body 100. The first housing 1 is fixedly connected to the speed reducer box 331.

[0088] The speed reducer box 331 is fixedly provided with a first bearing 200A and a second bearing 200B arranged along the axial direction of the first screw 311. The first screw 311 comprises a connecting segment 3111 and a threaded segment 3112. The connecting segment 3111 is located in the speed reducer box 331 and connected with the first bearing 200A and the second bearing 200B, so as to support the first screw 311 through the first bearing 200A and the second bearing 200B and enable the first screw 311 to rotate relative to the speed reducer box 331 and the first housing 1. The threaded segment 3112 is located in the first housing 1 and threadedly connected with the first nut 321.

[0089] The first transmission member 31 (for example, the first screw 311) can be rotatably connected with the first housing 1. A first through hole can also be formed at one end of the first housing 1 towards the speed reducer box 331, so that the first transmission member 31 passes through the first through hole, thereby realizing the rotation of the first transmission member 31 relative to the first housing 1.

[0090] In some embodiments, please refer to Figure 5 and Figure 6 , Figure 6 As shown in the internal structure diagram of the speed reducer box 331 of the electronic rearview mirror 200 in Figure 2 . The speed reducer 33 comprises a first gear 332, a transmission gear 333 and a second gear 334. The first gear 332 is connected to the output shaft of the driving member 4. Exemplarily, the driving member 4 is fixed to the speed reducer box 331, and the output shaft of the driving member 4 extends into the interior of the speed reducer box 331.

[0091] The second gear 334 is connected to the first transmission member 31, and specifically, the second gear 334 is connected to the connecting section 3111 of the first screw rod 311. The transmission gear 333 is in transmission connection between the first gear 332 and the second gear 334.

[0092] The driving member 4 works to drive the first gear 332 to rotate, the first gear 332 rotates to drive the second gear 334 to rotate through the transmission gear 333, and the second gear 334 drives the first transmission member 31 to rotate, so as to switch the electronic rearview mirror 200 between the working state and the storage state.

[0093] The cooperation of the first gear 332, the transmission gear 333 and the second gear 334 can make the power transmission between the driving member 4 and the first transmission member 31 more stable, so as to make the electronic rearview mirror 200 switch between the working state and the storage state more stably.

[0094] In some examples, the transmission gear 333 includes a third gear 3331 and a fourth gear 3332. The first rotating shaft 335 is also rotatably connected in the reduction box 331, and the third gear 3331 and the fourth gear 3332 are both connected to the first rotating shaft 335. The third gear 3331 is engaged with the first gear 332, and the fourth gear 3332 is engaged with the second gear 334. In this way, the driving member 4 rotates to drive the first gear 332 to rotate, so as to drive the third gear 3331 to rotate, the third gear 3331 rotates to drive the first rotating shaft 335 to rotate, so as to drive the fourth gear 3332 to rotate, and the fourth gear 3332 rotates to drive the second gear 334 to rotate, so as to drive the first transmission member 31 to rotate.

[0095] In other examples, the transmission gear 333 can also include only one gear engaged between the first gear 332 and the second gear 334, and the reduction effect is achieved by changing the transmission ratio of the first gear 332, the transmission gear 333 and the second gear 334.

[0096] In some embodiments, please continue to refer to Figure 5 and Figure 6 The electronic rearview mirror 200 further includes a third bearing 200C and a fourth bearing 200D, both of which are arranged in the reduction box 331 and connected to the reduction box 331. The third bearing 200C and the fourth bearing 200D are both connected to the output shaft of the driving member 4 and are respectively located on both sides of the first gear 332. The third bearing 200C and the fourth bearing 200D are used to support the output shaft of the driving member 4 and to make the output shaft of the driving member 4 rotate relative to the reduction box 331.

[0097] In some embodiments, please continue to refer to Figure 5 and Figure 6The electronic rearview mirror 200 further comprises a fifth bearing 200E and a sixth bearing 200F. The fifth bearing 200E and the sixth bearing 200F are arranged in the reduction gearbox 331 and connected to the reduction gearbox 331. The fifth bearing 200E and the sixth bearing 200F are connected to the first rotating shaft 335, and the transmission gear 333 is located between the fifth bearing 200E and the sixth bearing 200F. The fifth bearing 200E and the sixth bearing 200F are used to support the first rotating shaft 335 and to enable the first rotating shaft 335 to rotate relative to the reduction gearbox 331.

[0098] In some embodiments, referring to Figure 5 and Figure 7 , Figure 7 as Figure 5 shown in the enlarged view of the structure at A in FIG. 1. The second transmission member 32 is rotatably connected to the second housing 2 about a first axis. The first axis is in a direction that is consistent with a width direction of the vehicle 1000. In an example, the first axis is in a direction that is consistent with an axial direction of the first screw 311.

[0099] Rotation of the first transmission member 31 can also cause the second transmission member 32 to rotate about the first axis. That is, rotation of the first transmission member 31 can cause the second transmission member 32 to move in the width direction of the vehicle 1000 while also causing the second transmission member 32 to rotate relative to the second housing 2.

[0100] In some examples, referring to Figure 7 the first transmission member 31 comprises a first screw 311, and the second transmission member 32 comprises a first nut 321. The electronic rearview mirror 200 further comprises a seventh bearing 200G. The seventh bearing 200G is connected between the first nut 321 and the second housing 2.

[0101] In this way, rotation of the first transmission member 31 can cause the first nut 321 to move in the width direction of the vehicle 1000, and the first nut 321 can also rotate relative to the second housing 2 due to the seventh bearing 200G.

[0102] In this way, if the second housing 2 is blocked from moving due to an obstacle when the electronic rearview mirror 200 is being switched from the stowed state to the operating state, the second transmission member 32 can also be blocked from moving in the width direction of the vehicle 1000. In this case, if the drive member 4 is still operating, the first transmission member 31 can still rotate, which can cause the second transmission member 32 to rotate relative to the second housing 2, thereby avoiding damage to the second housing 2 and the second transmission member 32 due to the inability of the second transmission member 32 to rotate relative to the second housing 2.

[0103] Furthermore, while the first transmission member 31 drives the second transmission member 32 to move in the width direction of the vehicle 1000, it also drives the second transmission member 32 to rotate relative to the second housing 2, which can make the second housing 2 move relatively slowly relative to the first housing 1, thereby making the movement of the second housing 2 more stable.

[0104] In some embodiments, please continue reading Figure 5 and Figure 6 The second housing 2 includes a first sub-housing 21 and a second sub-housing 22. The first sub-housing 21 is connected to the first housing 1 and is connected to the second transmission member 32. The first sub-housing 21 can be moved relative to the first housing 1 in the width direction of the vehicle 1000 by the movement of the second transmission member 32 in the width direction of the vehicle 1000.

[0105] The second sub-housing 22 is connected to the first sub-housing 21 and is movable relative to the first sub-housing 21 along the width direction of the vehicle 1000; the camera 20 is connected to the second sub-housing 22. When the electronic rearview mirror 200 is in operation, a portion of the first sub-housing 21 is located outside the first housing 1, and a portion of the second sub-housing 22 is located outside the first sub-housing 21. At this time, the camera 20 is located outside the vehicle body 100 and can capture image information of the rear side of the vehicle 1000.

[0106] When the electronic rearview mirror 200 is in the retracted state, the first sub-shell 21 is located inside the first shell 1, and both the second sub-shell 22 and the camera 20 are located inside the first sub-shell 21. This allows the electronic rearview mirror 200 to be completely hidden inside the vehicle body 100, reducing wind resistance caused by the electronic rearview mirror 200. It also minimizes the space occupied by the electronic rearview mirror 200 within the vehicle body 100 when retracted, facilitating its placement within the vehicle body 100.

[0107] The second housing 2 may also include other sub-housings besides the first sub-housing 21 and the second sub-housing 22, that is, it includes multiple sub-housings. The multiple sub-housings are slidably connected in sequence, and two adjacent sub-housings slide relative to each other along the width direction of the vehicle 1000, so as to further reduce the space occupied by the electronic rearview mirror 200 in the vehicle body 100 when it is in the storage state.

[0108] In some embodiments, please refer to Figure 5 and Figure 8 , Figure 8 for Figure 5Enlarged structural diagram at point B. The transmission assembly 3 also includes a third transmission member 34 and a fourth transmission member 35. The third transmission member 34 is connected to the second transmission member 32 and can rotate with the second transmission member 32. The fourth transmission member 35 is connected to the second sub-housing 22. One of the third transmission member 34 and the fourth transmission member 35 has an internal thread, and the other has an external thread; the internal thread and the external thread are screwed together. Rotation of the third transmission member 34 can drive the fourth transmission member 35 to move along the width direction of the vehicle 1000.

[0109] In this way, while the first transmission member 31 drives the second transmission member 32 to rotate, the rotation of the second transmission member 32 can drive the third transmission member 34 to rotate. With the cooperation of the internal and external threads, the rotation of the third transmission member 34 can drive the fourth transmission member 35 to move along the width direction of the vehicle 1000, thereby causing the second sub-housing 22 to move relative to the first sub-housing 21 along the width direction of the vehicle 1000. Thus, through the cooperation of the first transmission member 31, the second transmission member 32, the third transmission member 34, and the fourth transmission member 35, only one driving member 4 is needed to move the first sub-housing 21 relative to the first housing 1 while simultaneously moving the second sub-housing 22 relative to the first sub-housing 21, thereby simplifying the structure of the electronic rearview mirror 200 and facilitating its control.

[0110] In some examples, please refer to Figure 5 , Figure 9 and Figure 10 , Figure 9 for Figure 5 The diagram shows the structure of the third transmission component 34 in the electronic rearview mirror 200. Figure 10 for Figure 9 A cross-sectional view of the third transmission component 34. The third transmission component 34 includes a transmission rod 341, the outer circumferential surface of which is provided with external threads. The fourth transmission component 35 includes a second nut 351, the second nut 351 being provided with internal threads. The second nut 351 is sleeved on the transmission rod 341.

[0111] The third transmission member 34 is provided with a clearance hole 342, which is recessed from the end face of the third transmission member 34 toward the second transmission member 32 in a direction opposite to the second transmission member 32. The first transmission member 31 passes through the second transmission member 32 and extends into the clearance hole 342 of the third transmission member 34. In this way, the clearance hole 342 facilitates the cooperation and connection of the first transmission member 31, the second transmission member 32, and the third transmission member 34.

[0112] In some embodiments, the fourth transmission member 35 is rotatably connected to the second sub-housing 22 about the first axis, and the third transmission member 34 is rotatable to drive the fourth transmission member 35 to rotate about the first axis. That is, the third transmission member 34 is capable of driving the fourth transmission member 35 to move in the width direction of the vehicle 1000 while also driving the fourth transmission member 35 to rotate relative to the second sub-housing 22.

[0113] In some examples, please refer to Figure 8 , the electronic rearview mirror 200 further comprises an eighth bearing 200H connected between the fourth transmission member 35 and the second sub-housing 22. In this way, the third transmission member 34 is capable of driving the fourth transmission member 35 to move in the width direction of the vehicle 1000 while also driving the fourth transmission member 35 to rotate relative to the second sub-housing 22.

[0114] In this way, during the switching of the electronic rearview mirror 200 from the stowed state to the working state, if the second sub-housing 22 is blocked by an obstacle and cannot move, if the driving member 4 is still working, the fourth transmission member 35 can be driven to rotate relative to the second sub-housing 22, thereby avoiding damage to the second sub-housing 22 and the fourth transmission member 35 due to the inability of the fourth transmission member 35 to rotate relative to the second sub-housing 22.

[0115] In addition, the third transmission member 34 is capable of driving the fourth transmission member 35 to move in the width direction of the vehicle 1000 while also driving the fourth transmission member 35 to rotate relative to the second sub-housing 22, which can also make the second sub-housing 22 move relatively slowly relative to the first sub-housing 21, thereby making the second sub-housing 22 move more smoothly.

[0116] In other examples, the fourth transmission member 35 can also be fixedly connected to the second sub-housing 22.

[0117] In some embodiments, please refer to Figure 7 , Figure 11 and Figure 12 , Figure 11 the structure of the first nut 321 in the electronic rearview mirror 200 shown in Figure 5 . Figure 12 the cross-sectional structure of the first nut 321 shown in Figure 11 . The first nut 321 comprises a first connecting portion 3211 and a second connecting portion 3212. The first connecting portion 3211 is connected to the side of the second connecting portion 3212 facing away from the fourth transmission member 35. Both the first connecting portion 3211 and the second connecting portion 3212 are provided with partial internal threads, and the internal threads of the first connecting portion 3211 and the second connecting portion 3212 form the internal threads of the first nut 321.

[0118] The internal thread of the first connecting part 3211 is threadedly connected to the first screw 311, and the first connecting part 3211 is connected to the first sub-housing 21. For example, the seventh bearing 200G is connected between the first connecting part 3211 and the second housing 2.

[0119] The second connecting portion 3212 is connected to the third transmission member 34. For example, the electronic rearview mirror 200 also includes a ninth bearing 200K, which is connected between the second connecting portion 3212 and the third transmission member 34. Thus, while the second transmission member 32 drives the third transmission member 34 to rotate, relative rotation can occur between the third transmission member 34 and the second transmission member 32, thereby slowing down the rotational speed of the third transmission member 34 and making the movement of the second sub-housing 22 relative to the first sub-housing 21 smoother.

[0120] In some examples, please refer to [link / reference]. Figure 10 The third transmission member 34 also includes a third connecting portion 343, which is a cylindrical structure and is connected to the end of the transmission rod 341 facing the second transmission member 32. The second connecting portion 3212 is located inside the third connecting portion 343, and the ninth bearing 200K is connected between the second connecting portion 3212 and the third connecting portion 343. The second transmission member 32 passes through the third connecting portion 343 and extends into the clearance hole 342 of the transmission rod 341.

[0121] In some other embodiments, the first transmission member 31 can also be a worm gear, and the second transmission member 32 can also be a worm. The driving member 4 drives the worm gear to rotate, which in turn drives the worm to rotate and simultaneously moves the worm along its axial direction. The axial direction of the worm can be aligned with the width direction of the vehicle 1000. In this way, it is also possible for one driving member 4 to drive the second sub-housing 22 to move relative to the first housing 1, while simultaneously moving the second sub-housing 22 relative to the first sub-housing 21.

[0122] In some embodiments, please refer to Figure 13 and Figure 14 , Figure 13 for Figure 5 The diagram shows the structure of the first housing 1 in the electronic rearview mirror 200. Figure 14 for Figure 13 The diagram shows a cross-sectional view of the first housing 1. The first housing 1 can be a cylindrical structure. Specifically, the first housing 1 can be a circular cylindrical structure or an elliptical cylindrical structure. This application uses an elliptical cylindrical structure as an example for illustration.

[0123] In some embodiments, please refer to Figure 15 and Figure 16 , Figure 15 for Figure 5A structural schematic view of the first sub-housing 21 in the electronic rearview mirror 200 shown, Figure 16 As Figure 15 A sectional structural schematic view of the first sub-housing 21 shown. The first sub-housing 21 can be a cylindrical structure. The first sub-housing 21 can be a circular cylindrical structure or an elliptical cylindrical structure. The present application is exemplarily described with the first sub-housing 21 being an elliptical cylindrical structure.

[0124] By setting the first housing 1 and the first sub-housing 21 as elliptical cylindrical structures, when the second transmission member 32 drives the first sub-housing 21 to move relative to the first housing 1, the relative rotation between the first sub-housing 21 and the first housing 1 during the movement can be reduced, thereby making the relative movement of the first sub-housing 21 and the first housing 1 more stable.

[0125] In some embodiments, please refer to Figure 14 and Figure 16 One of the first housing 1 and the second housing 2 is provided with a groove 11 extending along the width direction of the vehicle 1000, and the other of the first housing 1 and the second housing 2 is provided with a protrusion 23, at least part of which is located in the groove 11 and can slide in the groove 11.

[0126] By limiting the protrusion 23 with the groove 11, the second housing 2 can be limited in the circumferential direction to avoid rotating when moving relative to the first housing 1, thereby ensuring the stability of the movement of the second housing 2 relative to the first housing 1. Moreover, the groove 11 can also guide the protrusion 23, thereby guiding the second housing 2 when moving relative to the first housing 1, to further improve the stability of the movement of the second housing 2 relative to the first housing 1.

[0127] The present application is exemplarily described with the first housing 1 being provided with the groove 11 and the second housing 2 being provided with the protrusion 23. In some examples, the protrusion 23 is arranged on the outer circumferential surface of the first sub-housing 21. In some examples, the protrusion 23 extends along the width direction of the vehicle 1000.

[0128] In some examples, the number of the groove 11 can be one, and the number of the protrusion 23 can also be one.

[0129] The number of the groove 11 can also be multiple, and the number of the protrusion 23 can also be multiple. When the number of the groove 11 is multiple, the multiple grooves 11 are arranged at intervals along the circumference of the first housing 1. The multiple protrusions 23 are arranged at intervals along the circumference of the first sub-housing 21. One protrusion 23 is in sliding connection with one groove 11.

[0130] In some embodiments, please refer to Figure 14 and Figure 16The first shell 1 is provided with a first limiting portion 12 and a second limiting portion 13 which are arranged along the width direction of the vehicle 1000, and the second shell 2 is provided with a third limiting portion 24 which is located between the first limiting portion 12 and the second limiting portion 13.

[0131] In some examples, the third limiting portion 24 can be arranged on the first sub-shell 21. The first limiting portion 12 can be located on the side of the second limiting portion 13 which faces away from the second sub-shell 22.

[0132] In this way, when the electronic rearview mirror 200 is switched from the storage state to the working state, the third limiting portion 24 can be in contact with the second limiting portion 13 to limit the third limiting portion 24 by the second limiting portion 13, thereby avoiding the second shell 2 from being completely separated from the first shell 1, so as to ensure the stability of the electronic rearview mirror 200 in the working state.

[0133] When the electronic rearview mirror 200 is switched from the working state to the storage state, the third limiting portion 24 can be in contact with the first limiting portion 12 to limit the third limiting portion 24 by the first limiting portion 12, thereby ensuring the stability of the electronic rearview mirror 200 in the storage state.

[0134] In some examples, the first limiting portion 12 can be a boss structure, a rib structure, a columnar structure or the like arranged on the inner wall surface of the first shell 1. The second limiting portion 13 can be a boss structure, a rib structure, a columnar structure or the like arranged on the inner wall surface of the first shell 1. The third limiting portion 24 can be a boss structure, a rib structure, a columnar structure or the like arranged on the outer peripheral surface of the first sub-shell 21.

[0135] In other embodiments, a limiting structure can also be arranged on the first screw rod 311 to limit the first nut 321 by the limiting structure, thereby achieving the limiting of the electronic rearview mirror 200 in the working state and the switching state. Moreover, an electric control locking can also be designed in the motor control program to prevent the second shell 2 from being completely separated from the first shell 1.

[0136] In some embodiments, please refer to Figure 17 and Figure 18 , Figure 17 for Figure 5 the structural schematic view of the second sub-shell 22 in the electronic rearview mirror 200 shown in Figure 18 and Figure 17A cross-sectional structure schematic view of the second sub-housing 22 is shown. The second sub-housing 22 can be a cylindrical structure. The second sub-housing 22 can be a circular cylindrical structure or an elliptical cylindrical structure. The connection mode, limiting mode, anti-rotation mode and guiding mode between the second sub-housing 22 and the first sub-housing 21 can refer to the connection mode, limiting mode, anti-rotation mode and guiding mode of the first sub-housing 21 and the first housing 1 in any of the above embodiments, which will not be described here.
