Description

Technical Field

[0001] This utility model relates to automobile rearview mirrors, and more particularly to a shock-absorbing exterior rearview mirror for passenger vehicles. Background Technology

[0002] Buses experience varying degrees of vibration due to different road conditions during operation. These vibrations are transmitted through the vehicle body to the exterior rearview mirrors. Existing rearview mirrors with shock absorption functions have some damping structures to reduce the vibrations received by the rearview mirrors and reduce the impact of rearview mirror vibrations on the driver. However, these damping structures can only effectively filter vibrations under certain road conditions, and the damping effect is poor under other road conditions. Summary of the Invention

[0003] The purpose of this invention is to provide a car rearview mirror that can adapt to various road conditions.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A shock-absorbing exterior rearview mirror for passenger vehicles includes a bracket and a rearview mirror housing mounted on the bracket. A rearview mirror lens is installed inside the rearview mirror housing. The bracket includes a longitudinal bracket and transverse brackets located at the upper and lower ends of the longitudinal bracket. A support boss is fixed on the longitudinal bracket. From bottom to top, a first shock-absorbing pad, a rubber bushing, a second shock-absorbing pad, a pressure ring, and an external rotor stepper motor are sequentially mounted on the longitudinal bracket. The external rotor stepper motor has a rotating ring driven by the external rotor stepper motor to rotate. The rotating ring covers a portion of the pressure ring, and the inner wall of the rotating ring is provided with... The rearview mirror housing has a vertically extending, axially arranged strip-shaped transmission teeth. The outer circumferential surface of the pressure ring is provided with a transmission groove that mates with the strip-shaped transmission teeth. The pressure ring is threadedly connected to the longitudinal support. The rearview mirror housing is provided with a connecting part, which has a through hole. The connecting part is fitted onto a rubber bushing. The connecting part is located between a first damping pad and a second damping pad. The pressure ring presses the second damping pad against the upper end of the connecting part, and the connecting part presses the first damping pad against the upper end face of the support boss. The rubber bushing is interference-fitted with the longitudinal support, and the connecting part is interference-fitted with the rubber bushing.

[0006] With the above structure, the rotation of the outer rotor of the outer rotor stepper motor drives the rotating ring to rotate, which in turn drives the pressure ring to rotate, thereby adjusting the pressure on the first damping pad, the second damping pad, and the rubber bushing. This makes the pressure on the first damping pad, the second damping pad, and the rubber bushing match the vibration generated by the current road conditions, so that the damping effect of the rearview mirror is maximized. This utility model can adapt to various road conditions and improve the damping effect of the rearview mirror.

[0007] Preferably, in order to further prevent the rearview mirror from rotating axially, the outer peripheral surface and the inner peripheral surface of the rubber bushing are provided with protrusions, and the outer peripheral surface of the longitudinal bracket and the inner wall of the connecting through hole are provided with grooves corresponding to the protrusions.

[0008] Preferably, to prevent the outer rotor stepper motor, the first shock absorber, the second shock absorber, and the rubber bushing from getting wet by rainwater, the rearview mirror housing is provided with a cover, which covers the supporting boss, the first shock absorber, the rubber bushing, the second shock absorber, the pressure ring, the outer rotor stepper motor, and the connecting part.

[0009] Preferably, the external rotor stepper motor includes a housing, a rotor fixed to the inner wall of the housing, and a stator fixed to a longitudinal support. The housing has an upper end plate and a lower end plate, both of which are provided with bearings. The bearings are mounted on the longitudinal support, and the rotating ring is fixedly connected to the housing. Attached Figure Description

[0013] like Figure 1 and Figure 2As shown, this utility model discloses a shock-absorbing exterior rearview mirror for passenger vehicles, comprising a bracket and a rearview mirror housing 1 mounted on the bracket. A rearview mirror lens 2 is installed inside the rearview mirror housing. The bracket includes a longitudinal bracket 3 and transverse brackets 4 disposed at the upper and lower ends of the longitudinal bracket. A support boss 5 is fixed on the longitudinal bracket. From bottom to top, a first shock-absorbing pad 6, a rubber bushing 7, a second shock-absorbing pad 8, a pressure ring 9, and an external rotor stepper motor are sequentially mounted on the longitudinal bracket. The external rotor stepper motor has a rotating ring 10 driven to rotate by the external rotor stepper motor. The rotating ring covers a portion of the pressure ring. The inner wall of the rearview mirror housing is provided with vertically extending, axially arranged strip-shaped transmission teeth 11. The outer circumferential surface of the pressure ring is provided with a transmission groove 12 that mates with the strip-shaped transmission teeth. The pressure ring is threadedly connected to the longitudinal support. The rearview mirror housing is provided with a connecting part 13, which has a through hole. The connecting part is fitted onto a rubber bushing and is located between the first and second shock-absorbing pads. The pressure ring presses the second shock-absorbing pad against the upper end of the connecting part, and the connecting part presses the first shock-absorbing pad against the upper end face of the support boss. The rubber bushing is interference-fitted with the longitudinal support, and the connecting part is interference-fitted with the rubber bushing. The outer circumferential surface and inner circumferential surface of the rubber bushing are both provided with protrusions 14. The outer circumferential surface of the longitudinal support and the inner wall of the through hole of the connecting part are both provided with grooves corresponding to the protrusions. The rearview mirror housing is provided with a cover 15, which covers the support boss, the first shock-absorbing pad, the rubber bushing, the second shock-absorbing pad, the pressure ring, the outer rotor stepper motor, and the connecting part. The external rotor stepper motor includes a housing 16, a rotor 17 fixed to the inner wall of the housing, and a stator 18 fixed to a longitudinal support. The housing has an upper end plate 19 and a lower end plate 20. Both the upper end plate and the lower end plate are provided with bearings 21. The bearings are mounted on the longitudinal support. The rotating ring is fixedly connected to the housing.

[0014] With the above structure, the rotation of the outer rotor of the outer rotor stepper motor drives the rotating ring to rotate, which in turn drives the pressure ring to rotate, thereby adjusting the pressure on the first damping pad, the second damping pad, and the rubber bushing. This makes the pressure on the first damping pad, the second damping pad, and the rubber bushing match the vibration generated by the current road conditions, so that the damping effect of the rearview mirror is maximized. This utility model can adapt to various road conditions and improve the damping effect of the rearview mirror.
