Protective cover improved structure applicable to automobile chassis dynamometer

Abstract

The invention discloses a protective cover improved structure applicable to an automobile chassis dynamometer. The protective cover improved structure comprises a protective cover body which is of a hollow cuboid structure composed of a cover plate and four side plates without a bottom face. The side plate A is provided with an installation hole and a wire suspension slot. The two side plates B adjacent to the side plate A and the cover plate are each provided with a cooling fin structure. Guide grooves are formed side the two side plates B and provided with sliding rails. The sliding rails are fixed to the two sides of the cover plate respectively, and therefore the cover plate can slide along the guide grooves. The installation hole in the side plate A is provided with a heat dissipation structure which is a motor heat dissipation fan or a ventilation pipeline. The heat dissipation structure can be fixed to the side plate A of the protective cover through a bolt and a screw. When the protective cover improved structure is in use, the heat dissipation structure blows air into the protective cover, and therefore the purpose of accelerating motor heat dissipation and cooling can be achieved.

Description

technical field [0001] The invention relates to an auxiliary tool for automobile maintenance, in particular to an improved structure of a protective cover suitable for an automobile chassis dynamometer. Background technique [0002] Automobile testing can be divided into two categories: safety and environmental protection testing and comprehensive performance testing. Safety and environmental protection testing refers to the regular and irregular safe operation and environmental protection testing of vehicles. The purpose is to establish a safety and public nuisance monitoring system without disintegration of the vehicle, so as to ensure that the vehicle has a satisfactory appearance and good safety. Performance, limit the degree of environmental pollution of the car, so that it can operate under safe, efficient and low-pollution conditions. Comprehensive performance testing refers to the regular and irregular comprehensive performance testing of automobiles. The purpose i...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the motor of the chassis dynamometer is located below the ground and it is not easy to dissipate heat, and the ventilation effect and dustproof effect of the protective cover are not good. The protective cover has a heat dissipation structure, which can achieve the purpose of helping the motor to dissipate heat, and the dustproof effect is better
