[0001] The utility model relates to the technical field of automobile accessories, in particular to a foldable and concealable electronic rear exterior mirror. Background Art

[0002] The electronic rearview mirror is an indirect vision device that obtains a specified field of view through a system composed of a camera and a monitor. It includes electronic equipment such as a high-definition camera, a digital visual processing system, a safety system, and a liquid crystal display. It is a new type of rearview mirror that can replace the traditional optical rearview mirror.

[0003] Traditional optical exterior rearview mirrors are limited by the field of view of the law, and the size of the lens housing is large, and the fixed position requirements are high; general models can only add a rearview mirror folding function, and cannot be completely hidden inside the car. Electronic exterior rearview mirrors only have one camera on the outside, so the structure can be made very small. Considering the expensiveness of electronic products, in order to avoid damage to the electronic exterior rearview mirror, the folding and hiding function after parking is necessary. Utility Model Content

[0004] In order to overcome the disadvantages of the prior art that the electronic exterior rearview mirror cannot be folded and hidden and may be damaged after parking, the utility model proposes a foldable and hidden electronic exterior rearview mirror, which avoids damage by folding and hiding the electronic exterior rearview mirror after parking. The detailed technical solution is as follows:

[0005] A foldable and concealable electronic rearview mirror comprises a lifting device and an electronic rearview mirror that moves up and down along the height direction of the lifting device; the electronic rearview mirror comprises a base connected to the lifting device and a cantilever connected to a rotating shaft of the base; the cantilever comprises a mounting seat rotatably connected to the base and a shell rotatably connected to the mounting seat; the cantilever can rotate to the same direction as the base and move up and down along the height direction of the lifting device together with the base.

[0006] Furthermore, a camera is arranged on the shell, and the shell can rotate around the mounting seat toward the direction approaching the vehicle body.

[0007] Furthermore, the base includes a column, a second motor located above the main body, and a first rotating shaft drivingly connected to an output shaft of the second motor; and the cantilever is fixedly connected to the first rotating shaft.

[0008] Furthermore, the lifting device includes a mounting plate fixed to the inside of the vehicle body, a mounting frame fixed below the column, and a first motor fixed below the mounting frame.

[0009] Furthermore, the mounting plate is a "7"-shaped structure formed by welding two mutually perpendicular steel plates, wherein a groove is arranged on the back of one of the steel plates, and sliding grooves are symmetrically arranged on both sides of the relative position of the groove on the front side.

[0010] Furthermore, a long strip-shaped through hole is opened in the middle of the groove; and a rack is arranged on the inner surface of one side of the groove.

[0011] Furthermore, a gear matching the rack is provided at the end of the output shaft of the first motor, and the gear is meshed with the rack; and pulleys are provided at both ends of the first motor of the mounting frame, and the pulleys are located in the slide grooves.

[0012] According to any of the above embodiments, the present invention has at least the following beneficial effects: the utility model provides a foldable and hidden electronic rearview mirror, which can be rotated and raised and lowered along the height direction of the lifting device, thereby achieving the function of hiding the electronic rearview mirror when parking.

[0013] In terms of structural design, the base is raised and lowered along the lifting device by the first motor, and the cantilever can be rotated to the same direction as the base by the second motor. At the same time, the shell can be folded toward the body, which can effectively protect the electronic rearview mirror.

[0014] 1) The rotational connection between the housing 111 and the mounting seat 113 not only reduces the lateral distance of the vehicle body, but also has the functions of preventing collision damage and rotation buffering, thereby preventing the housing from breaking when encountering other vehicles or on narrow roads.

[0015] 2) The 7-shaped steel plate can be a one-piece piece or welded. The 7-shaped plate is used to provide multiple mounting holes, which can be used to diversify the mounting methods. The mounting holes on the side of the 7-shaped plate or the mounting holes on the front of the 7-shaped plate can be used, depending on the space boundary of the vehicle model.

[0016] 3) After the electronic exterior rearview mirror is completely lowered and hidden, the curved surface of the 111 is the same as the door shape, without any obtrusion and good aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Common electronic exterior rearview mirror structures in the prior art are as follows: Figure 1As shown, it includes a base 10 and a mirror body 20, the base 10 is fixedly connected to the vehicle body, and the mirror body 20 is connected to the rotating shaft of the base 10. A small motor connected to the rotating shaft is arranged in the mirror body 20, and the small motor receives the signal of the automobile circuit system and rotates according to the signal. During the rotation process, the gear is used for transmission and finally the mirror body 20 rotates around the rotating shaft, so that the mirror body 20 is parallel to the direction of the vehicle body, thereby realizing the folding of the rearview mirror. In the prior art, the rotating shaft of the electronic exterior rearview mirror is vertically arranged. Although the horizontal lateral distance of the vehicle body is reduced after folding, it is still located outside the vehicle body, and there is a risk of damage such as scratching and collision.

[0036] In order to reduce the risk of damage to the electronic exterior rearview mirror, the utility model proposes a foldable and concealable electronic exterior rearview mirror, the structure of which is as follows: Figure 2 As shown, it includes a lifting device 200 fixed to the interior of the vehicle body, and an electronic exterior rearview mirror 100 that can rotate around the lifting device 200 and move up and down with the lifting device 200.

[0037] The structure of the electronic exterior rearview mirror 100 is as follows: Figure 3 As shown, it includes a base 120 connected to the upper end of the lifting device 200, and a cantilever 110 connected to the rotation axis of the base 120. The structure of the cantilever 110 is as shown in FIG. Figure 4 As shown, it includes a mounting seat 113 whose lower end is rotatably connected to a base 120, and a housing 111 rotatably connected to an upper end of the mounting seat 113. An external camera 112 is also provided on the housing 111. The rotatable connection between the housing 111 and the mounting seat 113 is the same as that in the prior art, and is mainly used in the process of driving a vehicle. The housing 111 can be rotated toward the vehicle body to reduce the lateral distance of the vehicle body, and has the function of preventing collision damage and rotating buffering to avoid breaking when hitting a vehicle or a narrow road.

[0038] The structure of the base 120 is as follows Figure 5 As shown, it includes a column 121, a second motor 123 located above the column 121, and a first rotating shaft 124 connected to the output shaft of the second motor 123. The bottom of the base 120 is connected to the mounting frame 125 of the lifting device 200, and the first motor 122 is fixed to the base 120 through the mounting frame 125. The axis direction of the transmission shaft of the first motor 122 is along the X direction, the axis direction of the transmission shaft of the second motor 123 is along the Z direction, and the axis direction of the first rotating shaft 124 is along the Y direction. Figure 5In the figure, the X direction is the length direction of the vehicle body, the Y direction is the width direction of the vehicle body, and the Z direction is the height direction of the vehicle body. A gear 1221 is fixed on the transmission shaft of the first motor 122, and the gear 1221 is meshed with the rack 220 on the lifting device 200. The first rotating shaft 124 is fixedly connected to the mounting seat 113, and the second motor 123 can be connected to the transmission mechanism, and the first rotating shaft 124 is driven to rotate around the axis through the transmission mechanism. The transmission mechanism can refer to the existing technology, such as gear transmission, or the transmission can be carried out by setting matching threads at the end of the transmission shaft and the first rotating shaft. The second motor 123 is used to realize the rotation of the electronic rearview mirror, and the first motor 122 is used to realize the lifting of the electronic rearview mirror. In the utility model, the electronic rearview mirror 100 can be lifted and lowered along the Z-axis direction by the first motor 122, and rotated around the Y-axis by the second motor 123 and the first rotating shaft 124; at the same time, the housing 111 is rotatably connected to the mounting seat 113, so that the housing 111 rotates around the X-axis.

[0039] The lifting device 200 includes a mounting plate fixed to the interior of the vehicle body, a mounting frame 125 fixed below the base 120, and a first motor fixed below the mounting frame 125. The structure of the mounting plate is as follows: Figure 6 and Figure 2 As shown, it is a "7"-shaped structure formed by welding two mutually perpendicular steel plates and fixed inside the vehicle body. A groove 210 is provided on the back of the wider steel plate, and a long strip-shaped through hole 230 is opened in the middle of the groove 210. The inner surface of one side of the groove 210 is processed to form a rack 220 that matches the end gear 1221 of the first motor 122. The front of the wider steel plate is symmetrically formed with slide grooves 240 of equal cross-section on both sides of the groove 210. The mounting frame 125 is a slide groove 240 that matches the lifting device 200, and pulleys 1251 are provided at both ends of the first motor 122. The connection between the mounting frame 125 and the mounting plate is as shown in the figure. Figure 8 As shown, the first motor 122 is located on the front of the mounting plate, its output shaft passes through the groove 210 and the end gear 1221 is meshed with the rack 220, and the pulley 1251 of the mounting frame 125 is located in the slide groove 240. When the first motor 122 rotates, it drives the gear 1221 to move up and down along the rack direction. The principle is the same as that of the electric glass lifting, and the corresponding gravity is borne by the rotation of the first motor 122. The pulley 1251 is located in the slide groove 240 to limit the displacement of the electronic rearview mirror on the horizontal plane. The 7-shaped steel plate can be an integral part or can be welded separately. The function of the 7-shaped steel plate is to provide multiple mounting holes for easy connection with the vehicle body, and to diversify the installation methods. The mounting holes on the side of the 7-shaped plate or the mounting holes on the front of the 7-shaped plate can be used, depending on the spatial boundaries of the vehicle model.

[0040] The cantilever 110 and the base 120 are lowered together, and the arc-shaped free end of the housing 111 is flush with the door, and the appearance of the electronic exterior rearview mirror is consistent with the door shape. Figure 2The curved surface is the same as the door shape, which is not abrupt and more aesthetically pleasing. When the driver needs to lock the car or does not use the electronic exterior rearview mirror, the electronic exterior rearview mirror is hidden in the above way. This system is fully controlled by the electronic control system to achieve automation, and the electronic exterior rearview mirror is automatically extended and retracted when stopped and started. A maintenance control switch is added to the cab. If maintenance is required, press the switch, and the extended state is 20-30mm higher than the normal state, which meets the manual operation space for disassembly.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
