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 fixed 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 mechanism 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 vibrations can cause the rearview mirror to deflect, making it impossible to observe road information in a timely and accurate manner, thus affecting driving safety. In addition, this type of rearview mirror has low adjustment precision and lacks a sense of technology and aesthetics, making it difficult to meet the needs of high-end motorcycles. Utility Model Content

[0004] The purpose of this invention is to provide a rearview mirror rotation adjustment device that can be manually and electrically adjusted, with high positioning accuracy and good stability, so as to improve technological performance and driving safety.

[0005] The rearview mirror rotation adjustment device of this utility model includes a base installed on a vehicle and a bracket with a mirror housing. A motor mount is installed on the base, and a drive motor (not shown) and a rotation limiting plate connected to the drive motor and rotating with the drive motor are mounted on the adjustment base. One end of the bracket abuts against the rotation limiting plate. One end of the limiting shaft passes through the base, the motor mount, the rotation limiting plate and the bracket in sequence and is fixedly connected to a stop. The other end of the limiting shaft abuts against the base, and a spring is sleeved on the limiting shaft between the stop and the bracket. The surfaces of the bracket and the rotating limiting plate that abut against each other are arranged in a ring-shaped concave and convex pattern.

[0006] The rearview mirror rotation adjustment device has a base mounted on the motorcycle, a motor mount mounted on the base, a rotation limit plate mounted on the motor mount, and a bracket mounted on the rotation limit plate. A limit shaft passes through these components, is fitted with a spring, and is fixedly connected to a stop, thus sequentially connecting the base, motor mount, rotation limit plate, and bracket to form an axial limit. The rotation limit plate can rotate circumferentially under the drive of the motor. For example, a meshing gear pair or transmission rod can be installed between the motor and the rotation limit plate, allowing the motor to drive the rotation limit plate to rotate. The rotation limit plate, in turn, drives the bracket and its mirror housing to rotate via relatively concave and convex abutment surfaces, thereby achieving electric adjustment of the rearview mirror. Users can also manually adjust the rearview mirror by simply bending the bracket circumferentially; the bracket rotates circumferentially until bending stops, at which point the bracket is pressed against the rotation limit plate by the spring force. This rearview mirror rotation adjustment device can be electrically adjusted to greatly improve the technological sophistication and adjustment precision, or manually adjusted to ensure ease of operation. It allows for coarse manual adjustment followed by fine-tuning using a drive motor, enabling quick and accurate adjustment of the rearview mirror. Furthermore, the bracket and rotation limit plate are spring-loaded and positioned using a mating contact surface, resulting in high connection strength and effectively reducing the possibility of accidental displacement of the rearview mirror, thus ensuring driving safety.

[0007] Furthermore, the rotating limiting plate is provided with an arc-shaped limiting groove, and the motor base is equipped with a rotating limiting block located at the arc-shaped limiting groove.

[0008] Furthermore, the bracket and the rotating limiting plate are provided with a first limiting block and a second limiting block in opposite directions along the circumference.

[0009] Furthermore, the base, motor base, and rotating limit plate are respectively provided with shaft holes, the bracket is provided with an adjusting rod that extends into the shaft hole, the side of the bracket facing away from the base is provided with a mounting recess, the adjusting rod is provided with an adjusting hole that is coaxial with the shaft hole and passes through the mounting recess, the spring is provided in the mounting recess, and the limit shaft passes through the adjusting hole and the mounting recess and is connected to the stop.

[0010] Furthermore, the end of the adjusting rod is flat.

[0011] Furthermore, the base is provided with an annular positioning boss extending into the shaft hole of the motor mount.

[0012] Furthermore, the mating surfaces of the bracket and the rotating limiting plate are alternately provided with bosses, and the cross-sectional shape of the bosses is a trapezoid with inclined sides.

[0013] Furthermore, one end of the limiting shaft is provided with a slot, and the stop is clamped and fixed in the slot.

[0014] Furthermore, a washer is provided between one end of the spring and the stop; a washer and a flat bearing are provided between the other end of the spring and the bracket.

[0015] Furthermore, the outer wall of the rotating limiting plate is provided with several transmission block assemblies along the circumference, and each transmission block assembly includes two transmission blocks arranged opposite each other with a gap.

[0016] By setting up the aforementioned rearview mirror rotation adjustment device, the connection strength between components can be further improved, as well as the stability and accuracy of rearview mirror adjustment. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0030] This utility model proposes a rearview mirror rotation adjustment device.

[0031] Example 1, as Figure 1-9 As shown.

[0032] The rearview mirror rotation adjustment device of this embodiment includes a base 1 installed on a vehicle and a bracket 2 with a mirror housing. A motor mount 31 is installed on the base. A drive motor (not shown) and a rotation limiting plate 32 connected to the drive motor and rotating with the drive motor are installed on the adjustment base. One end of the bracket abuts against the rotation limiting plate. One end of the limiting shaft 4 passes through the base, the motor mount, the rotation limiting plate and the bracket in sequence and is fixedly connected to a stop 5. The other end of the limiting shaft abuts against the base, and a spring 6 is sleeved on the limiting shaft between the stop and the bracket. The surfaces of the bracket and the rotating limiting plate are arranged in a ring-shaped concave and convex pattern.

[0033] like Figure 1-9 As shown, the base is mounted on the motorcycle, the motor mount is mounted on the base, the rotating limit plate is mounted on the motor mount, and the bracket is mounted on the rotating limit plate. The limiting shaft passes through these components, is fitted with a spring, and is fixedly connected to a stop, thus sequentially connecting the base, motor mount, rotating limit plate, and bracket to form an axial limit. The rotating limit plate can rotate circumferentially under the drive of the drive motor. For example, a meshing gear pair or transmission rod can be installed between the drive motor and the rotating limit plate, allowing the drive motor to drive the rotating limit plate to rotate. The rotating limit plate, in turn, drives the bracket and its mirror housing to rotate via relatively concave and convex abutment surfaces, thereby achieving electrically adjustable rearview mirrors. Figure 8As shown, the bracket moves to different angles under the drive of the motor; the user can also manually adjust the rearview mirror by simply bending the bracket circumferentially, and the bracket will rotate circumferentially until the bending stops, at which point the bracket will be pressed against the rotation limit plate by the spring force. Figure 9 As shown, the bracket can be manually rotated 360° to meet a wider range of adjustment needs. This rearview mirror rotation adjustment device can be adjusted electrically or manually, and can also be coarsely adjusted manually first and then finely adjusted electrically, which greatly improves the convenience of operation and the accuracy of adjustment. Moreover, the high connection strength between the components can effectively reduce the risk of accidental rotation of the rearview mirror, thereby effectively ensuring driving safety.

[0034] like Figure 2 , 3 As shown in Figure 6, the rotating limiting plate 32 is provided with an arc-shaped limiting groove 33, and the motor base 31 is equipped with a rotating limiting block 13 located at the arc-shaped limiting groove. When the drive motor drives the rotating limiting plate to rotate, when the end of the arc-shaped limiting groove of the rotating limiting plate abuts against the rotating limiting block, the rearview mirror will be unable to continue to rotate, thereby preventing the rearview mirror from rotating excessively and colliding with the front of the vehicle.

[0035] The rearview mirror rotation adjustment device has shaft holes on the base 1, motor base 31, and rotation limiting plate 32. An adjusting rod 21 extends into the shaft hole on the bracket 2. A mounting recess 23 is provided on the side of the bracket facing away from the base. An adjusting hole, coaxial with the shaft hole and passing through the mounting recess, is provided on the adjusting rod. A spring 6 is disposed within the mounting recess. A limiting shaft 4 passes through the adjusting hole and the mounting recess and is connected to a stop 5. By using the adjusting rod to fit between the inner wall of the shaft hole on the base and the outer wall of the limiting shaft, a more stable limiting position can be formed, thereby improving connection strength and the stability and accuracy of adjustment. The end of the adjusting rod 21 is flat, which makes the bracket flatter, better covering the limiting shaft, preventing movement during operation, and facilitating demolding during production, thus improving production convenience and efficiency. Figure 4 As shown, the base 1 is also provided with an annular positioning boss 12 extending into the shaft hole of the motor base 31, thereby forming a further limiting and improving the connection strength between the base and the motor base.

[0036] The rearview mirror rotation adjustment device has protrusions 9 alternately arranged on the mating surfaces of the bracket 2 and the rotation limiting plate 32. The cross-sectional shape of the protrusions is a trapezoid with inclined sides. The recess between the two protrusions on the rotation limiting plate 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, and then the protrusion on the bracket moves to the adjacent recess, which is then locked and fixed again.

[0037] like Figure 6As shown, the outer wall of the rotating limiting plate 32 is provided with several transmission block assemblies along the circumference. Each transmission block assembly includes two transmission blocks 34 arranged opposite each other with a gap. The drive motor is connected to the transmission blocks of the rotating limiting plate through transmission components such as worm gears and gears, and realizes forward and reverse driving, so that the rearview mirror can be quickly adjusted around different directions. Moreover, its transmission structure is stable, safe and accurate.

[0038] like Figure 7 As shown, one end of the limiting shaft 4 is provided with a slot 43, and the stop 5 is clamped and fixed in the slot. Its structure is simple and easy to install and disassemble. A shim 10 is provided between one end of the spring 6 and the stop 5 to further improve the connection stability. A shim 10 and a plane bearing 20 are provided between the other end of the spring 6 and the bracket 2 to improve the stability and smoothness of the bracket rotation.

[0039] Example 2, as Figure 10 As shown.

[0040] In this embodiment, the rearview mirror rotation adjustment device has a first limiting block 7 and a second limiting block 8 arranged circumferentially opposite to the bracket 2 and the rotation limiting plate 32; the rest is the same as in embodiment one. This allows for limiting when the rearview mirror is manually rotated, preventing the rearview mirror or bracket from colliding with the front of the vehicle.

[0041] 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.
