Description

Technical Field

[0001] This utility model relates to rearview mirrors, and more particularly to a device for adjusting the angle of a rearview mirror. Background Technology

[0002] Rearview mirrors are widely used in various vehicles to help drivers observe the scene behind them and improve driving safety. At the same time, in order to accurately observe the scene behind them, rearview mirrors also need to be adjusted at a certain angle to meet the needs of different users.

[0003] Existing motorcycle rearview mirrors mainly consist of two parts: a mirror rod and a mirror housing with a lens. One end of the mirror rod is fixedly mounted to the motorcycle, while the mirror housing is rotatably mounted to the other end of the mirror rod via a ball joint. When the angle of the lens needs to be changed, the rider turns the mirror housing, causing the ball joint to rotate relative to the mirror rod until the lens is rotated to the appropriate angle. At this point, the ball joint is pressed against the mirror rod and fixed in place, thus adjusting the rearview mirror angle. However, this adjustment method is relatively simple, and the connection strength between the components is low. The rearview mirror will rotate even with slight impacts, and even when the motorcycle travels over uneven roads, the vibration of the vehicle can cause the rearview mirror to deflect, making it impossible to observe road information in a timely and accurate manner, thereby affecting driving safety. Utility Model Content

[0004] The purpose of this invention is to provide a rearview mirror adjustment device that is easy to use and has high structural strength, so as to reduce the possibility of the rearview mirror deflecting unexpectedly and improve driving safety.

[0005] The rearview mirror adjustment device of this utility model includes a base installed on a vehicle and a bracket with a mirror housing. An adjustment seat is also installed on the base. One end of the bracket and the adjustment seat abuts against each other to form a pressing surface. The adjustment seat and the base are provided with a shaft hole passing through the pressing surface. The end of the bracket is provided with an adjustment rod extending into the shaft hole. The adjustment rod has an adjustment hole coaxial with the shaft hole. There is also a limit shaft. One end of the limit shaft is provided with a limit structure between it and the base to prevent relative rotation between the two. The other end of the limit shaft passes through the adjustment hole and is fixedly connected to a stop. A spring is sleeved on the limit shaft between the stop and the bracket. A first limit block and a second limit block are also provided opposite to each other on the limit shaft and the bracket. The second limit block rotates with the bracket and abuts against the first limit block.

[0006] The rearview mirror adjustment device has a base mounted on a motorcycle. An adjustment seat and a limiting shaft are fixedly mounted on the base. An adjustment rod on the bracket fits between the inner wall of the shaft hole on the base and the outer wall of the limiting shaft. The bracket and adjustment seat form annular contact surfaces around the adjustment rod and shaft hole. Simultaneously, a limiting structure is provided between one end of the limiting shaft and the base, preventing circumferential rotation between them. A stop is fixedly installed at the other end of the limiting shaft, blocking the outward movement of the spring. This causes the other end of the spring to press the bracket against the adjustment seat, thus restricting the axial movement of the bracket and allowing it to rotate only around the limiting shaft. Furthermore, a first limiting block and a second limiting block are provided between the bracket and the limiting shaft. Because there is circumferential adjustment space between the first and second limiting blocks, the bracket can adjust the mirror housing and lens within a specific range until one end of the first and second limiting blocks abuts, preventing further rotation in a certain direction and thus avoiding excessive rotation of the mirror housing and collision with the front of the vehicle. This type of rearview mirror adjustment device is convenient and quick to operate. It uses components such as shaft holes, adjustment rods, limit shafts, stops, and springs for limiting and adjustment. The connection strength between the components is high, which can effectively reduce the possibility of the rearview mirror shifting unexpectedly and causing misalignment, thereby effectively ensuring people's driving safety.

[0007] Furthermore, a first limiting block is fixedly provided on the outer wall of the limiting shaft, and a second limiting block is fixedly provided at the end of the adjusting rod. The second limiting block rotates with the bracket and abuts against the first limiting block.

[0008] Furthermore, the first limiting block is integrally mounted on the limiting shaft.

[0009] Furthermore, the limiting structure includes a shaft plate disposed at the end of the limiting shaft and a limiting groove disposed on the base. The cross-sectional shape of the shaft plate is non-circular, and the shape of the limiting groove is adapted to the shaft plate. The shaft plate is disposed at the limiting groove. An annular reinforcing ring extends from the shaft plate to the outer wall of the limiting shaft, and a first limiting block is disposed on the end of the reinforcing ring facing away from the shaft plate.

[0010] Furthermore, the other end of the limiting shaft is provided with a slot, and the stop is clamped and fixed in the slot; the end of the bracket has a mounting recess coaxial with the shaft hole on the side facing away from the adjusting seat, and the spring is set in the mounting recess; a shim is provided between one end of the spring and the stop, and a shim and a plane bearing are provided between the other end of the spring and the bracket.

[0011] Alternatively, the bracket end has a mounting recess coaxially arranged with the shaft hole on the side facing away from the adjustment seat, and the spring is arranged in the mounting recess; the bottom of the mounting recess is provided with an annular groove, the second limiting block is arranged in the annular groove, and the first limiting block is installed on the limiting shaft and arranged in the annular groove.

[0012] Furthermore, the two opposite sides of the limiting shaft are provided with recessed and parallel positioning recesses, and there is a limiting plate fitted on the positioning recesses of the limiting shaft, with the first limiting block extending out from the limiting plate.

[0013] Furthermore, the thickness of the limiting plate is less than the depth of the annular groove.

[0014] Furthermore, the mating surfaces of the bracket and the adjusting seat are alternately provided with bosses, and the cross-sectional shape of the bosses is a trapezoid with inclined sides.

[0015] Furthermore, the adjusting seat includes a motor seat mounted on the base and a rotating limiting plate that abuts against the bracket via a pressing surface. Both the motor seat and the rotating limiting plate are provided with shaft holes. The motor seat is also equipped with a drive motor, which is connected to the rotating limiting plate and drives the rotating limiting plate to rotate.

[0016] By setting up the aforementioned rearview mirror adjustment device, the convenience and accuracy of rearview mirror adjustment can be further improved, as well as the possibility of the rearview mirror deflecting unexpectedly, thereby improving driving safety. Attached Figure Description

[0029] This utility model proposes a rearview mirror adjustment device.

[0030] Example 1, as Figure 1-5 As shown.

[0031] The rearview mirror adjustment device of this embodiment includes a base 1 installed on a vehicle (not shown) and a bracket 2 with a mirror housing (not shown). An adjustment seat 3 is also installed on the base. One end of the bracket and the adjustment seat abuts against each other to form a pressing surface. The adjustment seat and the base are provided with a shaft hole through the pressing surface. The end of the bracket is provided with an adjustment rod 21 that extends into the shaft hole. The adjustment rod has an adjustment hole coaxial with the shaft hole. There is also a limit shaft 4. One end of the limit shaft is provided with a limit structure between it and the base to prevent relative rotation between the two. The other end of the limit shaft passes through the adjustment hole and is fixedly connected to a stop 5. A spring 6 is sleeved on the limit shaft between the stop and the bracket. A first limit block 7 is fixedly provided on the outer wall of the limit shaft. A second limit block 8 is fixedly provided on the end of the adjustment rod. The second limit block rotates with the bracket and abuts against the first limit block.

[0032] The rearview mirror adjustment device has a base mounted on a motorcycle. An adjustment seat and a limiting shaft are fixedly mounted on the base. An adjustment rod on the bracket fits between the inner wall of the shaft hole on the base and the outer wall of the limiting shaft. The bracket and adjustment seat form annular abutment surfaces around the adjustment rod and shaft hole. Simultaneously, a limiting structure is provided between one end of the limiting shaft and the base, preventing circumferential rotation between them. A stop is fixedly mounted on the other end of the limiting shaft, blocking the outward movement of the spring. This causes the other end of the spring to press the bracket tightly against the adjustment seat, thus restricting the axial movement of the bracket and limiting its movement to circumferential rotation. The limiting shaft rotates; on the other hand, the limiting shaft and the bracket are respectively provided with a first limiting block and a second limiting block, and the first limiting block and the second limiting block are integrally set on the limiting shaft and the bracket, which not only improves the structural strength, but also improves the working accuracy of the rearview mirror adjustment. Since there is an adjustment space between the first limiting block and the second limiting block in the circumference, it ensures that the bracket can drive the mirror shell and the lens to adjust within a specific range until one end of the first limiting block and the second limiting block abuts, at which point the bracket can no longer rotate around a certain direction, thereby avoiding excessive rotation of the mirror shell and collision with the front of the vehicle. Figure 8 As shown.

[0033] The rearview mirror adjustment device, wherein the abutting surfaces of the bracket 2 and the adjustment seat 3 are arranged opposite each other along an annular concave and convex shape, as shown in the figure. Figure 5 As shown, protrusions 9 are alternately arranged on the mating surfaces of the bracket 2 and the adjusting seat 3. The cross-sectional shape of the protrusion is a trapezoid with inclined sides. The recess between the two protrusions on the adjusting seat is the limiting recess. When the bracket is rotated under force, it will move along the side of the trapezoid. At this time, the spring is compressed and contracted until it rotates to a certain angle. Then, the protrusion on the bracket moves to the adjacent recess, which is then locked and fixed again.

[0034] like Figure 2-4As shown, the limiting structure includes a shaft plate 41 disposed at the end of the limiting shaft 4 and a limiting groove 11 disposed on the base 1. The cross-sectional shape of the shaft plate is non-circular, and the shape of the limiting groove is adapted to the shaft plate. The shaft plate is disposed at the limiting groove and fixed to the base with screws, thereby effectively preventing the limiting shaft from rotating. The shaft plate 41 extends an annular reinforcing ring 42 to the outer wall of the limiting shaft 4. The first limiting block 7 is disposed on the end of the reinforcing ring facing away from the shaft plate. This can further increase the structural strength of the limiting shaft and the first limiting block, reduce stress concentration, and prevent the first limiting block from breaking due to excessive force. The other end of the limiting shaft 4 is provided with a slot 43, and the stop 5 is clamped and fixed at the slot. Its structure is simple and easy to install and disassemble. In addition, a washer 10 is provided between the end of the spring 6 and the stop 5 to further improve the connection stability; while a washer 10 and a plane bearing 20 are provided between the end of the spring 6 and the bracket 2 to improve the stability and smoothness of the bracket rotation. In addition, a mounting recess 23, coaxially arranged with the shaft hole, is provided on the side of the bracket 2 facing away from the adjusting seat 3. The spring is set in the mounting recess to better protect the spring and the plane bearing.

[0035] The rearview mirror adjustment device includes an adjustment base 3 comprising a motor base 31 mounted on a base 1 and a rotating limiting plate 32 abutting against a bracket 2 via a mating surface. Both the motor base and the rotating limiting plate have shaft holes. The motor base also houses a drive motor (not shown). The drive motor connects to the rotating limiting plate and drives it to rotate. For example, a meshing gear pair or transmission rod can be provided between the drive motor and the rotating limiting plate, allowing the drive motor to drive the rotating limiting plate to rotate. The rotating limiting plate then drives the bracket and its mirror housing to rotate via a boss, thus achieving electric adjustment. This not only makes operation easier but also increases adjustment precision, allowing for small-amplitude adjustments of the mirror housing and lens, better meeting the driver's needs. Figure 9 As shown.

[0036] Example 2, as Figure 6-7 As shown.

[0037] In this embodiment of the rearview mirror adjustment device, the bottom of the mounting recess 23 of the bracket 2 is provided with an annular groove 24, the second limiting block 8 is disposed in the annular groove, and the first limiting block 7 is installed on the limiting shaft 4 and disposed in the annular groove; the rest is the same as in embodiment one.

[0038] The first limiting block will not rotate relative to the limiting shaft. When the bracket is subjected to force and rotates, it will drive the second limiting block to rotate until the second limiting block abuts against the first limiting block, that is, it has rotated to the limit position. This structure can also meet the adjustment of the rearview mirror and reduce the possibility of the rearview mirror deflecting unexpectedly, thus improving driving safety.

[0039] The rearview mirror adjustment device has recessed and parallel positioning recesses 44 on two opposite sides of the limiting shaft 4, and a limiting plate 71 fitted onto the positioning recesses of the limiting shaft. The first limiting block 7 extends from the limiting plate for easy installation on the limiting shaft. Meanwhile, the thickness of the limiting plate 71 is less than the depth of the annular groove 24 to prevent the gasket from rubbing against the limiting plate during rotation, thus avoiding overheating or damage to the parts.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
