Description

Technical Field

[0001] This utility model relates to a vehicle rearview mirror. Background Technology

[0002] The rearview mirror is located at the front of the car's interior. It reflects the situation behind, to the sides, and below the car, allowing the driver to indirectly see these areas and expanding their field of vision. In the prior art, such as patent application number CN202021707286.4, a central rearview mirror assembly that is easy to install and remove includes a rearview mirror body and a mounting plate. The rearview mirror body is mounted inside the car via the mounting plate. The rearview mirror body has a vertically penetrating mounting opening. A fixing strip is fitted to the upper opening of the mounting opening, and multiple second threaded holes are formed through the fixing strip. Each second threaded hole contains a bolt. One end of the mounting plate is fixedly installed inside the car, and the other end is fixedly installed with a hook plate. The hook plate is L-shaped, and the overall shape of the mounting plate and hook plate is hook-shaped. The hook plate matches the shape and size of the mounting opening. The end of the hook plate away from the mounting plate has multiple first threaded holes, which are also used to mate with bolts. While this rearview mirror solves the installation and removal problem, it lacks an adjustment mechanism, failing to provide different drivers with a way to adjust the mirror. This results in a fixed field of view, making it impossible to dynamically adjust the mirror's angle according to the scene. Furthermore, differences in driver height and posture lead to variations in line-of-sight, resulting in situations where the field of view is too high, too low, or offset, and failing to cover key areas directly behind the vehicle. Utility Model Content

[0003] In view of the shortcomings of the prior art, this application provides a rearview mirror for a vehicle. The rearview mirror has multi-functional adjustment, which can adapt to the differences in height, sitting posture and other factors of different drivers, and ensure that the field of vision covers key areas. At the same time, the adjustment has a certain damping positioning, which can resist the problem of easy deviation caused by accidental touch or external force during driving.

[0004] To achieve the above objectives, this application provides a vehicle rearview mirror, including a clamping mechanism. The clamping mechanism is clamped and fixed at the installation location inside the vehicle. One end of the clamping mechanism is hinged to a connecting frame and is equipped with an anti-loosening fixing part. The connecting frame rotates axially at the hinge point to change the tilt angle. The other end of the connecting frame is ball-jointed to the mirror body. The connecting frame swings around the axis of the hinge point to change the height position of the mirror body. The mirror body adjusts its own angle by rotating through the ball-joint point.

[0005] Furthermore, the connecting frame includes a first hinge seat and a ball joint rod. The ball joint rod body is connected to the first hinge seat. The first hinge seat includes two parallel lugs. Each of the two lugs has a coaxial first pin hole at a corresponding position, through which the pin shaft passes to achieve hinge connection between the first hinge seat and the clamping mechanism.

[0006] Furthermore, the ball joint rod body is provided with a threaded hole, the first hinge seat has a pre-reserved connection hole corresponding to the threaded hole, and the screw passes through the connection hole and connects with the threaded hole.

[0007] Furthermore, the clamping mechanism includes a first clamping plate, a second clamping plate, and a locking member. Both the first clamping plate and the second clamping plate have bent portions at their upper ends, forming a clamping cavity between the relative bent portions and locking them together with the locking member.

[0008] Furthermore, the first clamping plate is provided with a second hinge seat facing the first hinge seat. The second hinge seat includes an ear seat, which has a second pin hole coaxial with the first pin hole. The ear seat is inserted between two parallel ear pieces.

[0009] Furthermore, the anti-loosening fixing part includes a threaded section provided on the pin shaft body, the threaded section passing through the second pin hole and the first pin hole and connecting with the nut, and the lug is provided with a groove corresponding to the nut.

[0010] Furthermore, damping positioning elements are provided between the two sides of the ear seat and the corresponding ear piece.

[0011] Furthermore, the damping positioning component is a bushing, which includes an annular body with a central hole for the pin shaft to pass through. The body is provided with multiple stepped segments with successively varying diameters along the axial direction, and an annular positioning step surface is formed between adjacent stepped segments for abutting against the end face of the ear piece and ear seat to achieve axial positioning.

[0012] Furthermore, the mirror body includes a mirror shell, a base with a hemispherical through groove on the mirror shell, a base plate connected to the mirror shell corresponding to the base plate, and a hemispherical groove on the base plate corresponding to the hemispherical through groove. The hemispherical groove and the hemispherical through groove together form a ball socket, allowing the ball head of the ball head rod to rotate in multiple directions within the ball socket.

[0013] Furthermore, the base plate is provided with a threaded through hole, and the mirror housing is provided with an adjusting rod that connects to the threaded through hole to adjust the ball joint damping of the ball joint.

[0014] Beneficial effects: This application assembles a rearview mirror by means of a clamping mechanism, a connecting frame, and a mirror body. One end of the connecting frame is hinged to the mirror body, allowing the mirror body to adjust its angle. The other end of the connecting frame is hinged to the clamping mechanism, allowing the connecting frame to rotate the mirror body around the hinge axis to change the position of the mirror body. This can adapt to the differences in height, sitting posture, etc. of different drivers and ensure that the field of vision covers key areas.

[0015] This application improves the damping effect of the adjustment point by adjusting the base plate at the ball joint to achieve damping adjustment of the ball socket to the ball head rod, and by setting a damping positioning component at the hinge of the connecting frame and the clamping mechanism. This can resist the problem of easy displacement caused by accidental contact or external force during driving, while the mirror body can be adjusted by applying a certain amount of force.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] For reference Figures 1-8 As shown, this application provides a vehicle rearview mirror, including a clamping mechanism 1, which is fixed in the vehicle installation location. The clamping mechanism 1 is hinged to one end of a connecting frame 3 and is equipped with an anti-loosening fixing part 2. The connecting frame 3 rotates axially at the hinge point to change the tilt angle. The other end of the connecting frame 3 is ball-jointed to the mirror body 6. The connecting frame 3 swings around the axis of the hinge point to change the height position of the mirror body 6. The mirror body 6 adjusts its own angle by rotating through the ball-joint point.

[0020] Specifically, see, for example Figure 8 As shown, the connecting frame 3 includes a first hinge seat 3-1 and a ball joint rod 3-2. The ball joint rod 3-2 is connected to the first hinge seat 3-1. The first hinge seat 3-1 includes two parallel lugs, each with a coaxial first pin hole 3-3 machined at a corresponding position, allowing the pin to pass through and achieve hinge connection between the first hinge seat 3-1 and the clamping mechanism 1. The first hinge seat 3-1 and the ball joint rod 3-2 can be integrally formed or detachably connected. In the preferred embodiment of this application, the ball joint rod 3-2 has a threaded hole, and the first hinge seat 3-1 has a pre-reserved connection hole corresponding to the threaded hole. A screw passes through the connection hole and connects to the threaded hole.

[0021] like Figure 2 As shown, the clamping mechanism 1 of this application is suitable for vehicles with pre-installed mounting plates. The clamping mechanism 1 includes a first clamping plate 1-1, a second clamping plate 1-2, and a locking member 1-3. Both the first clamping plate 1-1 and the second clamping plate 1-2 have bent portions at their upper ends, which fit snugly against the edge of the pre-installed mounting plate, forming a clamping cavity between the bent portions. The front and rear ends of the clamping cavity are respectively attached to the front and rear ends of the pre-installed mounting plate, and then locked by the locking member 1-3 to complete the installation. The bent portions ensure the firmness of the clamping mechanism 1 in the vehicle installation. The locking member 1-3 includes a nut 2-2 welded to the second clamping plate 1-2. The first clamping plate 1-1 has a circular hole corresponding to the nut 2-2, and a screw passes through the circular hole and connects to the nut 2-2, realizing the tightening adjustment of the second clamping plate 1-2 and the first clamping plate 1-1. Washers are arranged between the screws to prevent loosening, slippage, and to adjust the clearance. The first clamping plate 1-1 is provided with a second hinge seat facing the first hinge seat 3-1. The second hinge seat includes an ear seat 1-4. The ear seat 1-4 is provided with a second pin hole 1-5 coaxial with the first pin hole 3-3. The ear seat 1-4 is inserted between two parallel ear pieces. The pin shaft passes through the pin hole to achieve hinge. In order to ensure the fixation of the hinge angle, an anti-loosening fixing part 2 is provided. The anti-loosening fixing part 2 includes a threaded section provided on the pin shaft 2-1 body. The threaded section passes through the second pin hole 1-5 and the first pin hole 3-3 and connects with the nut 2-2. The ear pieces are provided with grooves corresponding to the threads. In order to prevent the pin shaft from driving the nut 2-2 to rotate synchronously, thereby losing the tightening function.

[0022] like Figure 4As shown, the mirror body 6 includes a mirror shell 6-1, a base 6-3 with a hemispherical through groove 6-2 on the mirror shell 6-1, and a base plate 7 connected to the mirror shell 6-1 corresponding to the base 6-3. The base plate 7 has a hemispherical groove 7-1 corresponding to the hemispherical through groove 6-2. The hemispherical groove 7-1 and the hemispherical through groove 6-2 together form a ball socket 8, allowing the ball head of the ball head rod 3-2 to rotate in multiple directions within the ball socket 8. In this application, the base plate 7 is preferably a triangular plate with round holes at two end corners for screws to pass through and connect to the pre-reserved threaded holes on the mirror shell 6-1 to fix the triangular plate to the mirror body 6. The other end corner has a threaded through hole 9. The end face of the mirror body 6 near the ball head rod 3-2 has a through hole corresponding to the threaded through hole 9. An adjusting rod 10 passes through the through hole and connects to the threaded through hole 9. The ball socket 8 is used to adjust the damping of the ball head by rotating the screw from the outside.

[0023] like Figure 7 As shown, further optimization is achieved by providing a damping positioning element 4 between the ear base 1-4 and the corresponding ear piece on both sides of the present application. Whether or not to install the damping positioning element 4 depends on the actual situation; in this application, it is preferred to install it. The damping positioning element 4 is preferably a bushing 5, including an annular body 5-1. The body 5-1 has a central hole 5-2 for the pin shaft to pass through. The body 5-1 has multiple stepped segments with successively varying diameters along the axial direction. An annular positioning step surface 5-3 is formed between adjacent stepped segments, which is used to abut against the end faces of the ear piece and the ear base 1-4 to achieve axial positioning. The damping positioning element 4 is designed to provide a preset friction force to resist natural loosening, while retaining adjustment space that can be overcome by human effort, thus improving the lubrication during rotation. This avoids the anti-loosening fastener being over-tightened, which would prevent rotation adjustment and require loosening of the anti-loosening fastener. Conversely, it avoids the anti-loosening fastener being over-loosened, which would result in a lack of support and stability, making it susceptible to displacement due to external forces, affecting the field of vision and causing driving safety problems. It ensures that the driver can adjust the viewing angle as needed, and can resist external forces, accidental touches, and component aging during driving, ensuring long-term stability of the angle.

[0024] Working principle: The ball joint 3-2 extends through the hemispherical groove 6-2 of the mirror housing 6-1 until the ball joint abuts against the hemispherical groove 6-2. It is then positioned by an installation plate. A mirror surface is then installed on the mirror housing 6-1 to form a mirror body 6 with the ball joint 3-2. A first hinge seat 3-1 is then installed at the end of the ball joint 3-2. A bushing 5 is installed in the second pin hole 1-5 of the second hinge seat. The second hinge seat with bushing 5 is inserted between the parallel lugs of the first hinge seat 3-1 and passes through the pin hole via a pin shaft. Connected to nut 2-2, the parallel lugs are clamped to the second hinge seat by the rotation of the pin shaft, so that the external force environment is not easily affected by the offset of the mirror body 6. At the same time, the presence of bushing 5 allows the driver to rotate and adjust the position of the rearview mirror with a little force. Then, the first hinge plate and the second hinge plate are abutted against the installation position in the vehicle. The installation plate in the vehicle is clamped in the clamping cavity and locked by locking piece 1-3 to fix it in the vehicle body. Then, the position and angle of the rearview mirror can be adjusted according to the different driving habits of the driver in the driver's seat.
