[0034] The exterior rearview mirror mechanism provided by the present application is arranged on the door of the vehicle, and includes an exterior rearview mirror body, a telescopic structure and an outer cover plate structure. The telescopic structure is telescopically arranged on the door and connected to the exterior rearview mirror body, and is used to drive the exterior rearview mirror body to extend out of the door or retract into the door. In this way, when the vehicle is turned off, the exterior rearview mirror body is retracted into the door through the telescopic structure, so that the exterior rearview mirror body can be hidden inside the door, thereby reducing the risk of vehicle scratches. The outer cover plate structure is movably arranged on the door, and covers the outer side of the exterior rearview mirror body when the exterior rearview mirror body is retracted into the door, and avoids the exterior rearview mirror body when the exterior rearview mirror body extends out of the door. In this way, when the exterior rearview mirror body is retracted into the door, the outer cover plate structure can cover the outer side of the exterior rearview mirror body, thereby preventing the exterior rearview mirror body from being exposed, and improving the overall aesthetics of the door.

[0035] Figure 1 Shown is a schematic structural diagram of the exterior rearview mirror mechanism 1 provided in the present application. Figure 2 for Figure 1 The exterior rearview mirror mechanism 1 is shown in a cross-sectional view with the exterior rearview mirror body 2 retracted into the vehicle door 5 . Figure 3 for Figure 1 The exterior rearview mirror mechanism 1 is shown in a side view in which the exterior rearview mirror body 2 is retracted into the vehicle door 5 and the exterior cover structure 4 covers the outer side of the exterior rearview mirror body 2 . Figure 4 for Figure 1 The exterior rearview mirror mechanism 1 is shown in a cross-sectional view in which the exterior rearview mirror body 2 extends out of the vehicle door 5 . Figure 5 for Figure 1 The exterior rearview mirror mechanism 1 is shown in a side view with the exterior rearview mirror body 2 extending out of the vehicle door 5 .

[0036] Combination Figure 1-Figure 5 As shown, the exterior rearview mirror mechanism 1 is arranged on the vehicle door 5, so that the driver can observe the road conditions outside the vehicle door 5. The exterior rearview mirror mechanism 1 includes an exterior rearview mirror body 2, a telescopic structure 3 and an outer cover plate structure 4. The telescopic structure 3 is telescopically arranged on the vehicle door 5 and connected to the exterior rearview mirror body 2, and is used to drive the exterior rearview mirror body 2 to extend out of the vehicle door 5 or retract into the vehicle door 5. For example, after the vehicle is started, the telescopic structure 3 drives the exterior rearview mirror body 2 to extend from the vehicle door 5, so that the driver can view the external environment conditions outside the vehicle body through the exterior rearview mirror body 2. After the vehicle is turned off, the telescopic structure 3 can drive the exterior rearview mirror body 2 to retract into the vehicle door 5, so that the exterior rearview mirror body 2 will not protrude outside the vehicle door 5, so that the purpose of hiding the exterior rearview mirror body 2 inside the vehicle door 5 is achieved, thereby reducing the risk of vehicle scratches. The outer cover plate structure 4 is movably arranged on the vehicle door 5, covers the outer side of the outer rearview mirror body 2 when the outer rearview mirror body 2 is retracted into the vehicle door 5, and avoids the outer rearview mirror body 2 when the outer rearview mirror body 2 is extended out of the vehicle door 5. Before the telescopic structure 3 drives the outer rearview mirror body 2 to extend from the vehicle door 5, the outer cover plate structure 4 moves to avoid the extension movement of the outer rearview mirror body 2; after the telescopic structure 3 drives the outer rearview mirror body 2 to retract from the outside of the vehicle door 5 to the inside of the vehicle door 5, the outer cover plate structure 4 moves to cover the outer side of the outer rearview mirror body 2, so as to prevent the outer rearview mirror body 2 from being exposed, and improve the overall aesthetics of the vehicle door 5.

[0037] Combination Figure 2-Figure 5 As shown, in some embodiments, the vehicle door 5 includes a cavity 6 and an opening 7 connected to the cavity 6; the telescopic structure 3 is disposed in the cavity 6. The cavity 6 of the vehicle door 5 is used as a space for placing the telescopic structure 3. The exterior rearview mirror body 2 extends out of the cavity 6 or retracts into the cavity 6 through the opening 7. In this way, through the opening 7, it is convenient for the telescopic structure 3 to drive the exterior rearview mirror body 2 to extend out of the cavity 6 or retract into the cavity 6, and the structural design is simple.

[0038] In some embodiments, the outer cover plate structure 4 includes a driving device 8 disposed in the vehicle door 5 and a cover plate 9 movably disposed outside the vehicle door 5. The cover plate 9 is disposed near the opening 7. The driving device 8 is connected to the cover plate 9 and is used to drive the cover plate 9 to cover the outside of the exterior rearview mirror body 2 or avoid the exterior rearview mirror body 2. In other words, before the telescopic structure 3 drives the exterior rearview mirror body 2 to extend from the vehicle door 5, the driving device 8 drives the cover plate 9 to rotate in a direction away from the opening 7, so that the cover plate 9 is separated from the opening 7, and the opening 7 is in an open state, thereby facilitating the extension movement of the exterior rearview mirror body 2; after the telescopic structure 3 drives the exterior rearview mirror body 2 to retract from the outside of the vehicle door 5, the driving device 8 drives the cover plate 9 to rotate in a direction close to the opening 7, so that the cover plate 9 and the opening 7 are closed, thereby preventing the exterior rearview mirror body 2 from being exposed through the opening 7, and improving the overall aesthetics of the vehicle door 5.

[0039] In some embodiments, the driving device 8 includes a first motor 10 and a transmission assembly 11; the transmission assembly 11 connects the first motor 10 and the cover plate 9; the first motor 10 drives the transmission assembly 11 to move, so that the transmission assembly 11 drives the cover plate 9 to move. Specifically, the first motor 10 provides a driving force to the transmission assembly 11, so that the transmission assembly 11 rotates, and the transmission assembly 11 drives the cover plate 9 to rotate. For example, when the cover plate 9 needs to cover the opening 7, the first motor 10 drives the transmission assembly 11 to rotate counterclockwise, so that the transmission assembly 11 drives the cover plate 9 to rotate counterclockwise, so that the cover plate 9 is closed with the opening 7, and the structure is simple, and the effect of the cover plate 9 covering the opening 7 is good, so that the concealment of the exterior rearview mirror body 2 is good.

[0040] Figure 6 for Figure 1 The schematic diagram of the structure of the outer cover plate structure 4 of the exterior rearview mirror mechanism 1 is shown. Figure 1 , Figure 6As shown, in some embodiments, the transmission assembly 11 includes a first gear 12, a second gear 13, and a transmission rod 14, which is connected to the first motor 10. The second gear 13 is meshed with the first gear 12, and the axial direction of the first gear 12 is perpendicular to the axial direction of the second gear 13. One end of the transmission rod 14 is connected to the second gear 13, and the other end is connected to the cover plate 9. The first motor 10 drives the first gear 12 to rotate, the first gear 12 drives the second gear 13 to rotate, the second gear 13 drives the transmission rod 14 to rotate around the axial direction of the transmission rod 14, and the transmission rod 14 drives the cover plate 9 to rotate. In this embodiment, the first motor 10 drives the first gear 12 to rotate, so that the first gear 12 and the second gear 13 rotate in coordination with each other, thereby driving the transmission rod 14 to rotate along its own axial direction, and then the cover plate 9 rotates with the rotation of the transmission rod 14. The cover plate 9 can be closed or opened with the opening 7 through rotational movement. In this way, through the mutual coordination of the first gear 12, the second gear 13 and the transmission rod 14, the rotation effect of the cover plate 9 is good, and the structure is relatively simple. In some embodiments, a through hole 26 is provided at one end of the cover plate 9 close to the transmission rod 14, and the transmission rod 14 is passed through the through hole 26. The cover plate 9 rotates around the axial direction of the transmission rod 14 through the through hole 26. In some embodiments, the transmission assembly 11 includes a motor shaft 27, and the motor shaft 27 is connected to the first motor 10. The first gear 12 is connected to the first motor by being sleeved on the motor shaft 27, so that the first motor 10 drives the motor shaft 27 to rotate, so that the motor shaft 27 drives the first gear 12 to rotate.

[0041] In some embodiments, the transmission assembly 11 further includes a third gear 24 and a transmission block 25. The third gear 24 is connected to the first motor 10. The transmission block 25 is arranged side by side with the transmission rod 14, and the length direction of the transmission block 25 is the same as the length direction of the transmission rod 14. The transmission block 25 is connected to the cover plate 9 and is in transmission connection with the third gear 24. The first motor 10 drives the third gear 24 to rotate, and the third gear 24 drives the transmission block 25 to move along the length direction of the transmission block 25, and the transmission block 25 drives the cover plate 9 to move along the length direction of the transmission block 25. In this embodiment, the third gear 24 is parallel to the above-mentioned first gear 12 and is arranged at intervals, and is also sleeved on the motor shaft 27. In this way, when the first motor 10 drives the first gear 12 to rotate, it also drives the third gear 24 to rotate. The rotation direction of the first gear 12 is the same as the rotation direction of the third gear 24. The bottom of the transmission block 25 is in transmission connection with the third gear 24, and the length direction of the transmission block 25 is perpendicular to the axial direction of the third gear 24. Thus, the rotation of the third gear 24 can drive the transmission block 25 to move along its own length direction, so that the transmission block 25 drives the cover plate 9 to move along the length direction of the transmission block 25. Thus, before the exterior rearview mirror body 2 extends out of the vehicle door 5, the cover plate 9 rotates with the rotation of the transmission rod 14, so as to be away from the opening 7, so that the opening 7 is in an open state. At the same time, the third gear 24 also drives the transmission block 25 to move, so that the transmission block 25 pulls the cover plate to move toward the direction of the vehicle door 5. Thus, the cover plate 9 has a good effect of avoiding the exterior rearview mirror body 2, so as to facilitate the extension movement or subsequent retraction movement of the exterior rearview mirror body 2. Furthermore, when the exterior rearview mirror body 2 is retracted into the door 5, the cover plate 9 rotates with the rotation of the transmission rod 14, so as to be close to the opening 7. At the same time, the third gear 24 also drives the transmission block 25 to move, so that the transmission block 25 pushes the cover plate to move away from the door 5. In this way, it is convenient for the cover plate 9 to cover the opening 7, so that the closing effect of the cover plate 9 and the opening 7 is good. In some embodiments, a gear portion 250 is provided at the bottom of the transmission block 25, and the transmission block 25 is meshed and connected with the gear portion of the third gear 24 through the gear portion 250.

[0042] like Figure 1As shown, in some embodiments, the telescopic structure 3 includes a turbine assembly 15 and a second motor 16, wherein one end of the turbine assembly 15 is connected to the exterior rearview mirror body 2, and the other end is connected to the second motor 16; the second motor 16 drives the turbine assembly 15 to move, so that the turbine assembly 15 drives the exterior rearview mirror body 2 to telescopically move. Specifically, when the vehicle is started, the second motor 16 drives the turbine assembly 15 to extend outward, so that the turbine assembly 15 pushes the exterior rearview mirror body 2 through the opening 7 and extends out of the cavity 6; when the vehicle is turned off, the second motor 16 drives the turbine assembly 15 to retract inward, so that the turbine assembly 15 pulls the exterior rearview mirror body 2 through the opening 7 and retracts into the cavity 6. In this way, through the mutual cooperation of the second motor 16 and the turbine assembly 15, the effect of extending the exterior rearview mirror body 2 out of the cavity 6 or retracting it into the cavity 6 is good, and the structural design is simple.

[0043] In some embodiments, the turbine assembly 15 includes a housing 17 and a turbine body 18 disposed in the housing 17; the housing 17 is connected to the inner wall of the cavity 6 to support the turbine body 18. In this embodiment, the housing 17 is located outside the turbine body 18, which plays a role in protecting the turbine body 18 on the one hand and supporting the turbine body 18 on the other hand. The turbine body 18 is connected to the second motor 16 and the exterior rearview mirror body 2. The second motor 16 drives the turbine body 18 to rotate, so that the turbine body 18 drives the telescopic movement of the exterior rearview mirror body 2. In this way, the structure is simple, and the transmission effect of the second motor 16, the turbine body 18 and the exterior rearview mirror body 2 is good.

[0044] In some embodiments, the turbine body 18 includes a turbine (not shown) and a worm gear 20, wherein one end of the worm gear 20 is connected to the turbine, and the other end of the worm gear 20 is connected to the exterior rearview mirror body 2; the turbine and the worm gear 20 rotate in coordination with each other, and the worm gear 20 drives the exterior rearview mirror body 2 to extend and retract. In this embodiment, the turbine and the worm gear 20 are transmission-connected, and the worm gear 20 is caused to extend out of the cavity 6 or retract into the cavity 6 through the coordinated rotation of the turbine and the worm gear 20, so that the worm gear 20 drives the exterior rearview mirror body 2 to extend out of the cavity 6 or retract into the cavity 6. For example, the second motor 16 drives the turbine to rotate counterclockwise, and the turbine drives the worm gear 20 in a first direction (such as Figure 4 The second motor 16 drives the turbine to rotate clockwise, and the turbine drives the worm 20 toward the second direction ((as shown in the X direction); Figure 4 The first direction is opposite to the second direction. In this way, the telescopic movement of the exterior rearview mirror body 2 is driven by the rotation of the turbine and the worm shaft 20, and the structure is simple and the design is ingenious. Of course, the telescopic movement of the exterior rearview mirror body 2 can also be achieved by other structures, which are not limited in this application.

[0045] In some embodiments, the telescopic structure 3 includes a connecting frame 21; the second motor 16 includes a mounting shell 22 and a motor body disposed inside the mounting shell 22. The mounting shell 22 is disposed outside the elevator body, and the mounting shell 22 is used to protect the motor body and facilitate the installation and fixation of the second motor 16. The connecting frame 21 connects the mounting shell 22 and the housing 17, and the connecting frame 21 is used to support the housing 17, so that the connection between the motor body and the turbine body 18 is convenient.

Although the present application has been disclosed as a preferred implementation mode as above, it is not used to limit the present application. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent implementation modes without departing from the scope of the technical solution of the present application.
