Buffer device for electro-tricycle carriage

Abstract

The invention relates to the technical field of electro-tricycles, and discloses a buffer device for an electro-tricycle carriage. The device comprises a frame main body, the top of the frame main body is provided with a carriage bracket, the outer wall of the carriage bracket is provided with a damping spring, the top of the damping spring is provided with a first sliding assembly, and a carriage body is arranged at the top of the first sliding assembly. According to the buffer device for the electro-tricycle carriage, the up-down impact force between the carriage body and the carriage support is preliminarily absorbed and damped through the damping springs, and then the transverse impact force of the carriage body is converted into the vertical impact force through the first sliding assembly, a second sliding assembly and a third sliding assembly; and the kinetic energy is secondarily absorbed through the damping springs, so that the effect of simple and convenient multi-stage damping is achieved, the situation of unsoldering or breakage caused by too large stress of the carriage due to bumping is avoided, the protection performance of the carriage of the electro-tricycle is improved, and the service life of the carriage of the electro-tricycle is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric tricycles, in particular to a buffer device for electric tricycle compartments. Background technique [0002] Electric tricycle (E l ectr ica l ly operated tricyc l e) is a three-wheeled transportation tool that is powered by a battery and driven by a motor to pull goods or people. , The traction battery can adapt to the requirements of continuous discharge for a long time. The battery can be used normally for two years, and the internal capacity will not decrease. The motor of the electric tricycle adopts a DC series-excited traction brush or brushless motor. The device is not easy to be damaged in normal use, which ensures strong output power. The simple understanding of electric sanitation vehicles is that they are driven by electricity. They have the advantages of environmental protection, beauty and reduced secondary pollution. They are used by relevant sanitation system departments. , the ...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a buffer device for electric tricycle carriages, which has the advantages of multi-stage buffering, etc., and solves the problem that the traditional electric tricycle buffer structure is single, and the carriage and frame are generally rigidly connected. During the process, the carriage is bumped and subjected to excessive force, which is prone to problems of desoldering or breakage
