Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycles, in particular to a shock-absorbing and stabilizing mechanism for a rear wheel seat of a tricycle. Background Art

[0002] Electric tricycles are three-wheeled vehicles that use batteries as power and motors as drive to transport goods or people. Electric tricycles usually have shock absorbers installed on the front wheels and leaf springs installed on the rear wheels to buffer the impact from the road during the driving of the electric tricycle and reduce the vibration of the electric tricycle body. The electric tricycle motor uses a DC series-excited traction brushed or brushless motor, and the motor is equipped with a speed-regulating and force-enhancing device. It is not easy to be damaged during normal use, ensuring strong output power.

[0003] However, when the electric tricycle is going uphill or downhill, especially when carrying heavy objects, its center of gravity will move backward or forward significantly, causing uneven force on both ends of the leaf spring of the rear wheel of the electric tricycle. The weight on one end of the leaf spring is greater than that on the other end, resulting in a decrease in the shock absorbing effect of the leaf spring or even breakage, affecting the stability of the electric tricycle during driving. Utility Model Content

It can play a buffering role when the tricycle goes uphill or downhill, avoid excessive impact force on one end of the leaf spring after the center of gravity of the tricycle changes, reduce the vibration of the tricycle when driving on the slope, and improve the stability of the tricycle when driving on the slope.

[0006] According to the shock-absorbing and stabilizing mechanism for the rear wheel seat of the tricycle, the shock-absorbing mechanism includes a rotatable hanging ear, a leaf spring and a support frame, the support frame is installed at the upper end of the rear axle, the leaf spring is a U-shaped structure with an opening upward, and the bottom of the leaf spring is installed in the support frame, the rotatable hanging ears are respectively located at both ends of the leaf spring and are fixedly connected to the leaf spring, and the rotatable hanging ears are installed at the lower end of the frame. It is used to buffer the impact from the road surface during the driving of the tricycle and achieve a shock-absorbing effect.

[0007] According to the shock-absorbing and stabilizing mechanism for the rear wheel seat of the tricycle, the upper end of the support frame is fixedly connected to a second spring shock absorber, and the upper end of the second spring shock absorber is fixedly connected to the frame, which is used to reduce the reciprocating speed of the leaf spring, thereby reducing the shock when the leaf spring rebounds after absorbing shock, and improving the stability of the tricycle during driving.

[0008] According to the rear wheel seat shock stabilization mechanism for a tricycle, the straight line formed by the connection between the first rotating frames is perpendicular to the rear axle. The first spring shock absorber connected with the first rotating frame is perpendicular to the vehicle body and the rear axle, so that the shock absorbing effect of the tricycle is ensured after the center of gravity of the tricycle moves when going uphill.

[0009] According to the three-wheeled vehicle rear wheel seat shock absorbing and stabilizing mechanism, the first spring shock absorbers on the two second rotating frames are in an eight-shaped shape, and are used to absorb the impact from the road surface when the three-wheeled vehicle tilts forward and backward.

[0010] The beneficial effects of the utility model are as follows: the first spring shock absorber on the second rotating frame at both ends of the installation plate plays a buffering effect after the center of gravity changes during the uphill or downhill process of the tricycle, avoiding excessive weight on one end of the leaf spring and reducing the shock absorbing effect on the tricycle, thereby improving the stability of the tricycle running on slopes. At the same time, the second spring shock absorber can assist the leaf spring in buffering the impact from the road surface, reduce the frequency of the reciprocating motion of the leaf spring, reduce the vibration frequency during the driving of the tricycle, and further improve the stability of the tricycle.
