Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycles, and particularly relates to a rear-wheel shock-absorbing mechanism for an electric tricycle. Background Technique

[0002] Electric tricycles, with their advantages of strong applicability, flexibility, simple maintenance, convenient repair, and low price, can move flexibly among narrow roads. Electric tricycles are equipped with a reverse switch, which can conveniently realize the forward and reverse driving functions, and this is very practical in narrow alleys and lanes. Whether driving or parking, they are very convenient, and are widely used in short-distance transportation fields such as families, urban and rural areas, individual rentals, factory areas, mining areas, sanitation, and community cleaning.

[0003] The existing electric tricycles mainly have the following disadvantages during use: the shock-absorbing structure is poor, or even lacks a shock-absorbing structure. As a result, when the electric tricycle is loaded and drives on a bumpy road section, the body of the tricycle vibrates greatly, affecting the comfort, and the structure of the tricycle body is prone to damage under long-term vibration. Therefore, there is room for improvement. Content of the Utility Model

[0019] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0020] Some embodiments of the present utility model will be described below in conjunction with the drawings.

[0021] Embodiment 1:

[0022] Combined with Figures 1-3As shown in the figure, this embodiment provides a rear-wheel shock-absorbing mechanism for an electric tricycle, including: a main body mechanism 100.

[0023] Among them, the main body mechanism 100 includes a vehicle frame 110, beam frames 120 symmetrically arranged and hinged on both sides of the vehicle frame 110, wheels 130 rotatably installed at the ends of the beam frames 120, support seats 140 fixed on the beam frames 120, leaf springs 150 installed at the tops of the support seats 140, top plates 160 hinged on both sides of the leaf springs 150, rubber air bags 170 fixed at the tops of the top plates 160, and a carriage 180 installed at the tops of the rubber air bags 170.

[0024] The vehicle frame 110, as the main part of the electric tricycle, is used to install other components. Supports are symmetrically fixed on both sides of the vehicle frame 110. The beam frame 120 includes a U-shaped frame 121 with its end hinged to the vehicle frame 110 and a fixed shaft 122 fixed on one side of the U-shaped frame 121. The end of the U-shaped frame 121 is rotatably connected to the support, facilitating the rotation of the U-shaped frame 121 and the fixed shaft 122. The fixed shaft 122 is used to install the wheel 130, facilitating the rotation of the wheel 130. Through the above settings, the wheels 130 on both sides become independent suspension mechanisms, and the left and right wheels 130 can bounce independently without interference, thereby reducing the tilt and vibration of the vehicle body.

[0025] The support seat 140 is used to fixedly sleeve the bottom end on the fixed shaft 122 for installing the leaf spring 150. The middle of the bottom end of the leaf spring 150 is fixed on the support seat 140, which is used to transfer the weight of the carriage 180 to the fixed shaft 122 and buffer between the carriage 180 and the fixed shaft 122 to reduce the impact of the wheel 130 bouncing on the carriage 180.

[0026] The bottom end of the top plate 160 is hinged to the end of the leaf spring 150 for installing the rubber air bag 170. The bottom end of the rubber air bag 170 is fixed to the middle of the top plate 160, and the top end is connected to the bottom end of the carriage 180, which can buffer the shock between the leaf spring 150 and the carriage 180 and buffer the fine vibrations on the leaf spring 150, further improving the stability of the carriage 180.

[0027] In addition, through holes 161 are opened on both sides of the top plate 160, and a plurality of round rods 181 are symmetrically fixed at the bottom end of the carriage 180. The round rods 181 are movably fitted in the round holes to limit the movement of the carriage 180, so that the carriage 180 can only bounce up and down.

[0028] Working principle and usage process of the utility model: When the electric tricycle is running, since the vehicles on both sides are installed on the beam frame 120, and the beam frame 120 is hinged with the vehicle frame 110, when one side of the vehicle bounces, it will not affect the running of the wheels 130 on the other side. At the same time, when the wheels 130 bounce, it drives the support seat 140 to bounce up and down. During the up and down bouncing of the support seat 140, the leaf spring 150 buffers the shock force of the up and down bouncing of the support seat 140 through its own deformation, avoiding the transmission of vibration to the carriage 180. At the same time, the rubber airbag 170 realizes buffering between the leaf spring 150 and the carriage 180 by utilizing the compressibility of the air inside it, avoiding the transmission of tiny vibrations on the leaf spring 150 to the carriage 180.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
