Description

Technical Field

[0001] The present invention relates to the technical field of vehicle accessories, and in particular to a rearview mirror system and a vehicle. Background Art

[0002] Traditional physical mirrors have a narrow field of view and large blind spots. In severe weather conditions such as heavy rain, snow, or dense fog, physical mirrors are easily affected by rain and fog, resulting in blurred vision and affecting the driver's safety.

[0003] Camera rearview mirrors can provide a wider field of view, reduce blind spots, and allow drivers to better observe the vehicle's surroundings, improving driving safety. However, if a problem occurs with the camera rearview mirror or its signal circuit, the camera rearview mirror will become unusable, seriously affecting the vehicle's driving safety.

[0004] Therefore, the current rearview mirror system is equipped with a camera and a physical mirror at the same time. Although it improves the reliability of the rearview mirror system to a certain extent, the rearview mirror system integrates a camera and a physical mirror at the same time, and the structural area is relatively large, which will also produce certain resistance to the vehicle's driving.

[0005] How to improve the reliability of the rearview mirror system as much as possible while reducing the resistance to driving is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] The purpose of the embodiment of the present application is to provide a rearview mirror system with high reliability and low wind resistance. Another purpose of the embodiment of the present application is to provide a vehicle including the rearview mirror system.

[0007] An embodiment of the present application provides a rearview mirror system, comprising:

[0008] The mounting body is equipped with a camera and a physical mirror, and the mounting body can rotate around a rotation axis; the mounting body has a first side wall and a second side wall set at an angle, the physical mirror is located on the first side wall, and the lens part of the camera is located on the second side wall; when the mounting body is rotated to a first position around the rotation axis, the physical mirror is in a rear-view working position; when the mounting body is rotated to a second position around the rotation axis, the physical mirror is at least partially hidden inside the vehicle door system, and the lens part can be in the rear-view working position.

[0009] In the embodiment of the present application, the rearview mirror system is equipped with both a camera and a physical mirror. When the rearview mirror system is in use, the relative position of the installation body relative to the vehicle body can be selected according to the driver's needs, so as to choose to use the camera or the physical mirror for rearview work, and the reliability and flexibility of use are relatively high. Since the physical mirror and the lens part are respectively located on the first side wall and the second side wall of the installation body, the areas of the two side walls can be reasonably set according to the sizes of the physical mirror and the lens part. And the first side wall and the second side wall are arranged at an angle. In this way, when the physical mirror is in the rearview working position, the first side wall is substantially perpendicular to the driving direction, and the second side wall where the lens part is located can be parallel to the driving direction or arranged at an angle, and the windward area is relatively small, which is beneficial to reducing wind resistance. Compared with the prior art where the physical mirror is located outside the door system when the camera is working, in the embodiment of the present application, the lens part is in the rearview working position, and at least part of the physical mirror is hidden inside the door system, greatly reducing the wind resistance generated by the physical mirror.

[0010] In addition, the present application also provides a vehicle, including a vehicle body, and the rearview mirror system according to any one of the above is provided on the vehicle body.

[0011] Since the vehicle has the above rearview mirror system, it also has the above technical effects of the rearview mirror system. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] The inventors of the present application have conducted a large amount of research on the rearview mirror system that simultaneously has a physical mirror and a camera in the current technology. It is found that the current rearview mirror system is generally: the camera and the physical mirror are installed on the same side of the mounting bracket of the rearview mirror system. Whether the camera is in the rearview working state or not, the physical mirror is always in the rearview working state. Obviously, the windward area of the rearview mirror system with this structure is relatively large, and the resistance to the vehicle is relatively large.

[0024] After in-depth research and exploration, the inventors of the present application have proposed a rearview mirror system with relatively small wind resistance and relatively high use reliability.

[0025] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present application, the following further details the embodiments of the present application in conjunction with the accompanying drawings and specific embodiments.

[0026] Please refer to Figures 1 to 9 , Figure 1 which is an assembly schematic diagram of the rearview mirror system and the door system in an embodiment of the present application; Figure 2 is Figure 1 a side view of the structure shown; Figure 3 is Figure 2 a C-C cross-sectional view of the structure shown; Figure 4 is a schematic structural view of the rearview mirror system in an embodiment of the present application; Figure 5 is Figure 4 a schematic diagram of the physical mirror of the rearview mirror system shown in the rearview working state; Figure 6 is Figure 5 a top view of the structure shown; Figure 7 is Figure 6 a schematic diagram of the camera of the rearview mirror system shown in the rearview working state; Figure 8 is Figure 7 an A-A cross-sectional view of the structure shown; Figure 9 is Figure 1 a schematic structural view of the door system in the structure shown.

[0027] Please refer to Figures 1 to 3 , an embodiment of the present application provides a vehicle, including a door system 200 and a rearview mirror system. The door system 200 may include a door body 210, and the door body 210 may be a sheet metal part, a plastic part, a combination of metal and plastic, or other materials with a predetermined strength. The door body 210 is hinged or pivotally connected to the vehicle body, and the door body 210 can provide an installation base for some components on the vehicle. A window frame may be provided on the door body 210, and a glass 220 is installed at the position of the window frame. In the embodiment of the present application, the door system 200 is the door system 200 on one side close to the driver's or passenger's position.

[0028] The rearview mirror system in the embodiment of the present application is installed on both the left and right sides of the vehicle. The accompanying drawings only show a schematic diagram of the combination of the door system 200 and the rearview mirror system on the driver's side. The driver can better understand the situation behind, on the side, and below the vehicle through the rearview mirror system, providing a basis for driving decisions and reducing the occurrence of accidents.

[0029] Please refer to Figure 4 , in the embodiment of the present application, the rearview mirror system includes a mounting body 1, a camera 3, and a physical mirror 2. The physical mirror 2 is usually a convex mirror, which has a diverging effect on light, can collect the scenes in a wider area into the mirror, and allows the driver to observe an image smaller than the actual object, with a wider field of view, which helps to understand the conditions around the vehicle. Of course, the physical mirror 2 can also be a plane mirror. The plane mirror uses the reflection of light, and the presented image will not be distorted, and can truthfully show the scene behind the vehicle to the driver.

[0030] The mounting body 1 in the embodiment of the present application can rotate around a rotation axis 4. Specifically, the mounting body 1 is rotatably connected to the triangular area of the door body 210. Please refer to Figure 2 and Figure 9 Understand, that is, the triangular area of the door body 210 has a mounting position, and the mounting body 1 can be rotatably connected to the mounting position through the rotation axis 4. Of course, in some embodiments, the mounting body 1 can also be installed on the fender beside the engine hood, which can provide a wider field of view, reduce the occlusion of the vehicle body from the line of sight, and is beneficial to observing the situation behind and on the side of the vehicle.

[0031] The rotation of the mounting body 1 can be achieved in a variety of ways, such as by providing a motor drive system. The motor drive system includes at least a motor, which is mounted on the vehicle door body 210 or the vehicle body. The motor directly or indirectly drives the rotating shaft 4 to rotate, thereby achieving rotation of the mounting body 1 about the rotating shaft 4. The motor can be a micro DC motor. The output shaft of the motor can be directly connected to the rotating shaft 4. Of course, the output shaft of the motor can also be connected to the rotating shaft 4 through a transmission mechanism. For example, the motor drive system can further include a transmission mechanism such as a gear mechanism or a connecting rod mechanism. The motor drives the rotating shaft 4 to rotate through the gear mechanism and / or the connecting rod mechanism. In this way, the installation position of the motor is relatively flexible.

[0032] Of course, the driving component for driving the mounting body 1 to rotate is not limited to the motor drive system described above, and may also be a hydraulic or other driving component, as long as it can drive the mounting body 1 to rotate around the rotating shaft 4 .

[0033] The drawings in the embodiments of the present application do not show a motor drive system, but this does not hinder those skilled in the art from understanding and implementing the technical solution.

[0034] Please combine Figure 4 and Figure 5 It is understood that in the embodiment of the present application, the mounting body 1 has a first side wall 11 and a second side wall 12 arranged at an angle, the physical mirror 2 is located on the first side wall 11, and the lens portion 31 of the camera 3 is located on the second side wall 12. Specifically, the camera 3 can be directly mounted on the second side wall 12. Of course, a light-transmitting hole can be provided on the second side wall 12 for light to enter the lens portion 31. In a specific example, the mounting body 1 is a shell structure having an inner cavity, and the camera 3 is at least partially installed in the inner cavity of the shell. A light-transmitting hole is provided on the second side wall 12 at a position corresponding to the lens portion 31. In order to protect the lens portion 31, a transparent protective cover 5 is further installed on the light-transmitting hole.

[0035] The included angle between the first side wall 11 and the second side wall 12 can be 0 to 180°. Preferably, the included angle between the two is less than or equal to 90°, so as to minimize the volume of the installation body 1 and reduce the wind resistance of the installation body 1.

[0036] Please refer to Figure 5 and Figure 6 When the mounting body 1 rotates about the rotation axis 4 to the first position, the physical mirror 2 is in the rearview operating position; at this point, the camera 3 can be in either an operating or non-operating state. In this position, the driver can at least observe the vehicle's side and rear through the physical mirror 2.

[0037] Please refer to Figure 7 and Figure 8When the mounting body 1 rotates about the rotation axis 4 to the second position, the physical mirror 2 is hidden inside the door system 200, and the lens head 31 can be in the rear-view working position. In other words, when the mounting body 1 rotates from the first position to the second position, the physical mirror 2 rotates toward the door system 200, and at least a portion of the physical mirror 2 can be hidden inside the door system 200. In other words, the portion of the mounting body 1 that mounts the physical mirror 2 can rotate inside the door system 200.

[0038] The rearview mirror system in the embodiment of the present application is equipped with both a camera 3 and a physical mirror 2. When the rearview mirror system is in use, the relative position of the mounting body 1 relative to the vehicle body can be selected according to the driver's needs, so as to select whether to use the camera 3 or the physical mirror 2 for rearview operation, thereby achieving high reliability and flexibility. Because the physical mirror 2 and the lens head 31 are respectively located on the first side wall 11 and the second side wall 12 of the mounting body 1, the areas of the two side walls can be reasonably set according to the size of the physical mirror 2 and the lens head 31. In addition, the first side wall 11 and the second side wall 12 are arranged at an angle. In this way, when the physical mirror 2 is in the rearview working position, the first side wall 11 is approximately perpendicular to the driving direction, while the second side wall 12 where the lens head 31 is located can be arranged parallel to the driving direction or at an angle, so that the windward surface is relatively small, which is conducive to reducing wind resistance. Compared with the current technology in which the physical mirror 2 is located outside the door system 200 when the camera 3 is working, in the embodiment of the present application, the lens head 31 is in the rear-view working position, and the physical mirror 2 is at least partially hidden inside the door system 200, which greatly reduces the wind resistance generated by the physical mirror 2.

[0039] Please refer again Figure 4 and Figure 6 It is understood that in the embodiment of the present application, the second side wall 12 is at least partially located on the side of the first side wall 11 facing away from the physical mirror surface 2, that is, the second side wall 12 can be partially located on the side of the first side wall 11 facing away from the physical mirror surface 2, or the second side wall 12 can be entirely located on the side of the first side wall 11 facing away from the physical mirror surface 2. Generally, the mirror head 31 is relatively small in size and the required installation area is also relatively small. Therefore, the width of the second side wall 12 can be smaller than the width of the first side wall 11. It is understood that the projection of the second side wall 12 on the plane of the physical mirror surface 2 can be at least partially located on the first side wall 11, that is, the projections of the first side wall 11 and the second side wall 12 on the plane of the physical mirror surface 2 at least partially overlap. In this way, when the physical mirror surface 2 is in the rearview working position, the sum of the windward surfaces formed by the first side wall 11 and the second side wall 12 is relatively small. In particular, when the projection of the second side wall 12 is completely within the range of the first side wall 11, it is basically sufficient to only consider the windward surface formed by the first side wall 11.

[0040] In the embodiment of the present application, the second side wall is connected to the side of the first side wall 11 away from the rotation axis 4. In the embodiment of the present application, the rotation axis 4 of the mounting body 1 is substantially parallel to the height direction of the vehicle body. In other words, the mounting body 1 rotates around the rotation axis 4 in the plane formed by the length and width of the vehicle body. That is, the physical mirror surface 2 can rotate around the rotation axis 4 to expand or close relative to the door body 210. Figure 2 When the door system shown is installed on a vehicle body and closed, the vehicle body's length is parallel to the X-direction, the vehicle body's height is parallel to the Y-direction, and the direction perpendicular to the paper is the vehicle body's width. The angle between the first side wall 11 and the second side wall 12 is less than or equal to 90 degrees. Thus, when the physical mirror 2 is in the rearview operating position, the second side wall 12 is as parallel to the vehicle body's length as possible. Alternatively, the further away from the first side wall 11, the closer the second side wall 12 is to the vehicle body, i.e., the second side wall 12 is tilted toward the vehicle body. This minimizes wind resistance caused by the second side wall 12.

[0041] In one example, the second sidewall 12 extends a predetermined length perpendicular to the plane of the physical mirror 2. This allows the second sidewall 12 to be substantially parallel to the direction of travel when the physical mirror 2 is in the rearview operating position, negligibly impacting the wind resistance generated by the vehicle. Furthermore, in this embodiment, the lens portion 31 is located at the end of the second sidewall 12 distal from the first sidewall 11. This position is minimized from the vehicle body to prevent the vehicle body from interfering with the field of view of the camera 3, thereby facilitating a wider field of view and improving driving safety for the driver.

[0042] Please refer again Figure 4 and Figure 6 In one example, the second sidewall 12 includes a first wall surface 121 and a second wall surface 122 along its extension direction. The first wall surface 121 is connected to the first sidewall 11, and the second wall surface 122 is connected to the end of the first wall surface 121 away from the first sidewall 11. The angle between the first wall surface 121 and the plane of the physical mirror surface 2 is less than 90 degrees. This allows the second sidewall 12 to be positioned as close to the side of the first sidewall 11 as possible to the side away from the physical mirror surface 2. The second wall surface 122 is perpendicular to the plane of the physical mirror surface 2, and the camera unit is located on the second wall surface 122, which facilitates the installation of the camera unit.

[0043] The first wall 121 can be directly connected to the first side wall 11, or alternatively, connected via an intermediate wall. To enhance the aesthetics of the mounting body 1, the connection between the second side wall 12 and the first side wall 11 can be formed as an arc-shaped bend 13. The second side wall 12 also includes a third wall 123, which is substantially parallel to the first wall 121 and connected between the second wall 122 and the bend 13.

[0044] Of course, in order to minimize the weight of the mounting body 1, the mounting body 1 can be generally in an L-shaped structure, and the first side wall 11 and the second side wall 12 are part of the circumferential side walls of the L-shaped structure. Specifically, the circumferential side walls of the L-shaped structure further include a first arc wall 14, a second arc wall 15, and a turning section 13. The first side wall 11, the turning section 13, the second side wall 12, the second arc wall 15, and the first arc wall 14 enclose the circumferential side walls of the mounting body 1, and the rotating shaft 4 is installed at one end of the first arc wall 14 close to the first side wall 11. The arc wall is also beneficial to reducing wind resistance.

[0045] Please refer to Figure 8 , as described above, the mounting body 1 includes a housing with an inner cavity. The housing rotates around the rotating shaft 4, the camera 3 is fixed in the inner cavity, the housing has a first side wall 11 and a second side wall 12, and a light-transmitting hole is provided on the second side wall 12 to allow light to enter the lens portion 31. The camera 3 is located in the inner cavity of the housing, which can not only provide good protection for the camera 3, but also minimize the driving wind resistance and improve the aesthetics of the vehicle.

[0046] In the embodiment of the present application, the mounting body 1 further includes a skeleton main body. The skeleton main body is at least partially located in the inner cavity. The camera 3 is fixed to the skeleton main body, and the rotating shaft 4 is also installed on the skeleton main body. The skeleton main body can be a metal skeleton, and of course it can also be a plastic skeleton. The skeleton main body and the housing can be integrally formed or separately provided. The skeleton main body can improve the service strength of the mounting body 1.

[0047] Please refer to Figure 3 and Figure 9 Understand that in the embodiment of the present application, the door system 200 includes a door main body 210. The door main body 210 has a groove 211. When the mounting body 1 rotates around the rotating shaft 4 to the second position, the physical mirror 2 is hidden inside the groove 211. The outer contour of the groove 211 can be substantially the same as the outer contour of the first side wall 11, and the bottom of the groove 211 can be matched with the physical mirror 2. In one example, the bottom of the groove 211 can be a plane. The groove 211 is formed on the door main body 210 by means of processes such as stretching or stamping, and the forming process is relatively simple.

[0048] The vehicle has the above-mentioned rearview mirror system, so it also has the above-mentioned technical effects of the rearview mirror system.
