[0039] In the utility model, Figure 1 、 2 , 3, 4 provides an embodiment, wherein the fixed part 10, support rod 20 and connecting part 30 are integrally formed, one end of the fixed part 10 is used for bolt connection with the top of the vehicle, one end extends obliquely downward to form the support rod 20, in some optional embodiments, the angle of the fixed part 10 extending obliquely downward is 30-50 degrees, preferably 45 degrees. The center of the support rod 20 is hollow, and the other end is further bent and extended to form the connecting part 30.

[0040] The fixed part 10 is the part bolted with the top of the vehicle, which includes a mounting piece 11 and a support base 12. The mounting piece 11 is flat and provided with a first positioning hole 111, a second positioning hole 112, a first mounting hole 113, a second mounting hole 114, a third mounting hole 115 and a fourth mounting hole 116 according to the latest standard of GB 15084-22 "Performance and Installation Requirements for Indirect Vision Devices of Motor Vehicles".

[0041] The mounting piece 11 has a protrusion extending in the direction perpendicular to the plane of the mounting piece 11, which extends step by step to the support rod 20 to form the support base 12, and the top end of the support base 12 is provided with a first interface 121 and a second interface 122 respectively.

[0042] It can be understood that the positions and sizes of the first positioning hole 111, the second positioning hole 112, the first mounting hole 113, the second mounting hole 114, the third mounting hole 115, and the fourth mounting hole 116 in the embodiment are designed and adjusted according to GB 15084-22 “Performance and Installation Requirements for Indirect Vision Devices of Motor Vehicles” and production needs, and those skilled in the art can design and adjust them according to their own needs.

[0043] Meanwhile, the first interface 121 and the second interface 122 serve as a connection between the control circuit and the power supply circuit, and those skilled in the art can add or reduce the elements according to design needs.

[0044] Similarly, the hollow part of the support rod 20 in the embodiment mainly serves to reduce weight while ensuring the overall structural strength, so as to reduce the weight of the overall component and the production cost, and at the same time, the control circuit and the power supply circuit can pass through the hollow part, and those skilled in the art can adjust the component according to their own production needs.

[0045] As shown in Figure 2 , Figure 3 and Figure 4 , one end of the support rod 20 is folded outward to form a cylindrical connecting rod 31, the connecting rod 31 is hollow in the middle and further extends outward to form a spherical head component 32, in some optional embodiments, the spherical head component 32 is a spherical component, and petal-shaped protrusions are arranged on both sides of the connection between the spherical head component 32 and the connecting rod 31 along the horizontal direction of the ground, which are a first support petal 321 and a second support petal 322.

[0046] It is worth mentioning that the “horizontal” described in the present application refers to a plane or direction perpendicular to the direction of the earth's gravity, i.e., parallel to the ground. Specifically, when a component, surface, or operating plane is described as “horizontal”, it means that it is consistent with the horizontal plane of the earth in space and forms a 90° angle with the direction of gravity, and it can also refer to a reference working plane for the driving state of the automobile.

[0047] The spherical head component 32 is hollow in the middle and has a smooth inner wall, the spherical head component 32 is cut or cast along the two parallel sides extending in the horizontal direction to form two planes extending in the horizontal direction, which are a first blocking part 323 and a second blocking part 324, the inner walls of the corresponding spherical head component 32 of the first blocking part 323 and the second blocking part 324 are further thickened, so that the inner wall spacing of the first blocking part 323 and the second blocking part 324 is less than the inner diameter of the spherical head component 32.

[0048] Meanwhile, the other end of the ball head part 32 further extends outward to form a cylindrical ball head extension 325, which has an inner diameter smaller than the diameter of the universal ball.

[0049] As shown in Figure 4 the ball head extension 325 is cut or cast along two sides perpendicular to the horizontal direction to form two planes perpendicular to the horizontal direction, namely a first limiting part 326 and a second limiting part 327. The first limiting part 326 and the second limiting part 327 further thicken the inner wall of the ball head extension 325, so that the inner wall of the first limiting part 326 and the inner wall of the second limiting part 327 are spaced apart by a distance smaller than the inner diameter of the ball head extension 325.

[0050] It can be understood that the first support lobe 321 and the second support lobe 322 in the embodiment serve to improve the strength of the connection between the ball head part 32 and the connecting rod 31, so as to ensure that the support will not be broken due to external forces in the horizontal direction during use. In the specific implementation process, those skilled in the art can adjust the shape, size, and position of the first support lobe 321 and the second support lobe 322 according to the materials used in production and their own design needs.

[0051] In the prior art, the connection between the plastic part of the vehicle rearview mirror and the support is usually embedded connection by using a universal ball. The universal ball is embedded in the ball head part and moves by rotating in the ball head part to drive the universal ball connecting rod, so as to realize multi-directional rotation of the rearview mirror.

[0052] When the rearview mirror is deflected by a large angle under the influence of external force or its own gravity, the universal ball connecting rod will abut against the edge of the ball head part, forming a lever structure. When the external force further acts in the deflection direction, the universal ball will be deflected by a large angle in the ball head part under the influence of the lever action, causing the rearview mirror to be deflected by a large angle, thereby affecting driving and causing safety hazards.

[0053] Further, when the rearview mirror is subjected to a force in a certain direction that is too large, the universal ball will move towards the edge of the ball head part. When the external force acting on the rearview mirror exceeds the limit, the universal ball will be detached from the ball head part under the influence of the lever action, causing the rearview mirror to fall off the support, affecting driving and causing safety hazards.

[0054] The utility model discloses a ball head part 32 connects section extension ball head extension 325, when the rearview mirror is excessively deflected under the action of external force, the connecting rod of universal ball can form lever structure with the ball head extension 325, and the support point can further away from the edge of the ball head part 32, thereby limiting the excessive deflection of universal ball in the ball head part 32, thereby limiting the deflection angle of rearview mirror to some extent.

[0055] In addition, the longer the length of the ball head extension 325, the more obvious the limiting effect on the connecting rod of universal ball, thereby making the limiting effect of rearview mirror more obvious, and the anti-falling effect of rearview mirror is more obvious. Therefore, in order to obtain better technical effect, the extension length of the ball head extension 325 in the embodiment should be greater than or equal to 5mm, that is, not less than 5mm, and in the specific implementation, the person skilled in the art can adjust according to the design needs.

[0056] Further, since the inner wall spacing between the first blocking part 323 and the second blocking part 324 in the ball head part 32 is less than the inner diameter of the ball head part 32, the movement range of the universal ball between the first blocking part 323 and the second blocking part 324 is further limited, thereby making the deflection angle of the rearview mirror in the direction of the first blocking part 323 and the second blocking part 324 further smaller, avoiding excessive deflection of the rearview mirror in the direction.

[0057] Similarly, since the ball head extension 325 has a first limiting part 326 and a second limiting part 327, and the spacing between the inner walls of the first limiting part 326 and the second limiting part 327 is less than the inner diameter of the ball head extension 325, the movement range of the connecting rod of universal ball between the first limiting part 326 and the second limiting part 327 is further limited, thereby making the deflection angle of the rearview mirror in the direction of the first limiting part 326 and the second limiting part 327 further smaller, avoiding excessive deflection of the rearview mirror in the direction.

[0058] 11. It is worth mentioning that, in order to obtain better limiting effect of the rearview mirror, the first blocking part 323 and the second blocking part 324 in the embodiment are parallel to each other, and perpendicular to the first limiting part 326 and the second limiting part 327, and the first limiting part 326 and the second limiting part 327 are parallel to each other, in other words, the shortest distance line of the first blocking part and the second blocking part is perpendicular to the shortest distance line of the first limiting part and the second limiting part.

[0059] In this way, the movement of the reflector in the four vertical directions is limited, and the range of movement is simultaneously affected by the thickness of the inner walls of the first blocking part 323, the second blocking part 324, the first limiting part 326 and the second limiting part 327. The skilled person can adjust the positions and the thickness of the inner walls of the first blocking part 323, the second blocking part 324, the first limiting part 326 and the second limiting part 327 according to the design requirements, so as to limit the movement of the rearview mirror within the ideal range, prevent the rearview mirror from falling off, and avoid excessive deflection of the rearview mirror at various angles to affect driving.

[0060] Meanwhile, when the universal ball is horizontally rotated to a set angle in the ball head part, the universal ball connecting rod is earlier against the first limiting part 326 or the second limiting part 327, so that the universal ball connecting rod is earlier subjected to the opposite resistance force from the ball head extension part 325, further limiting the range of movement of the universal ball when working in the support, thereby avoiding excessive deflection of the rearview mirror in the horizontal direction.

[0061] Further, the increased thickness of the inner walls of the first blocking part 323 and the second blocking part 324 limits the movement of the universal ball and further enhances the structural strength of the first blocking part 323 and the second blocking part 324, so that the parts are not prone to cracking and breaking during frequent use, thereby prolonging the service life of the support as a whole.

[0062] Similarly, the increased thickness of the inner walls of the first limiting part 326 and the second limiting part 327 limits the movement of the universal ball connecting rod and further enhances the structural strength of the first limiting part 326 and the second limiting part 327, so that the parts of the first limiting part 326 and the second limiting part 327 are improved in strength and are not prone to cracking and breaking during frequent use, thereby prolonging the service life of the support as a whole.

[0063] The support described in the utility model, when installing, the smooth plane of the mounting part 11 faces the vehicle installation position, the first positioning hole 111 and the second positioning hole 112 are aligned with the corresponding positioning holes on the installation surface at the same time, the bolt is simultaneously inserted into the first mounting hole 113, the second mounting hole 114, the third mounting hole 115 and the fourth mounting hole 116 and inserted into the corresponding vehicle mounting hole for bolt connection, so as to realize the fixed connection between the rearview mirror support and the vehicle body.

[0064] In addition, the universal ball at the end of the rearview mirror plastic part is aligned with the ball head extension part 325, and the universal ball is pressed into the ball head part 32 through the ball head extension part 325 by using a pressing device.

[0065] It can be understood that the pressing method used in the embodiment is one of the commonly used techniques in the field, and other installation methods can be selected according to the site conditions during implementation, including but not limited to hot mounting and cold mounting. After the installation of the plastic part is completed, the reflector lens can be further installed into the plastic part, that is, the installation of the basic structure is realized.

[0066] In the embodiment, the rearview mirror support has a first interface 121 and a second interface 122, which can provide line connection of electronic devices. One end of the connecting line is connected with the sockets of the first interface 121 and the second interface 122, the wire part extends to the connecting rod 31 through the hollow part of the support rod 20, and extends to the rearview mirror plastic part through the hollow parts of the connecting rod 31, the ball head part 32 and the ball head extension 325, and is connected with the line interface on the plastic part, so as to realize the digitization of the whole rearview mirror.

[0067] It can be understood that the first interface 121 and the second interface 122 in the embodiment mainly provide the data transmission interface of electronic devices, and the skilled in the art can adjust and increase or decrease the components according to the needs of their own functions during implementation.

[0068] In use, the force received by one end of the reflector is transmitted to the bottom of the support base 12 through the support rod 20, and is transmitted to the top of the vehicle through the mounting part 11. The connecting rod 31 can further extend the rearview mirror, and the user can control the swing of the rearview mirror to the desired position by hand rotation or operation of the vehicle-mounted device. When the vehicle is in a bumpy state, the reflector lens will be affected by force from different directions according to the bumpy state of the vehicle, and the action force will make the universal ball embedded in the ball head part 32 rotate and deviate. When the deviation reaches a set angle, the universal ball will abut against the inner wall of one of the first blocking part 323 and the second blocking part 324, or the universal ball connecting rod will abut against the inner wall of one of the first limiting part 326 and the second limiting part 327, so that the deviation of the universal ball / connecting rod is prevented, thereby preventing the rearview mirror from being deflected too much during the bumping process and affecting driving.

[0069] At the same time, when the reflector is subjected to a larger force, the ball head extension 325 will abut against the universal ball connecting rod to prevent the universal ball from approaching the edge of the ball head part 32, and further, when the reflector is subjected to a larger force, the ball head extension 325 will abut against the universal ball to prevent the universal ball from falling out, thereby preventing the reflector from falling.

[0070] The foregoing describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
