Self-locking type vehicle top cover

Abstract

A self-locking type vehicle top cover comprises a push-and-pull guide rod, a guide plate and a sliding member; the guide plate is fixed at the top cover; one end of the push-and-pull guide rod is hinged to a vehicle frame assembly; the sliding member is fixed at the other end of the push-and-pull guide rod and slidably arranged on the guide plate; the guide plate is provided with a sliding portion and a self-locking portion, the sliding portion extends in a direction parallel to one side edge of the top cover, and the self-locking portion is formed in a manner that one end of the sliding portion vertically extends towards an outer side of a vehicle; and the sliding member is capable of sliding to and fro along the sliding portion in the direction parallel to the side edge of the top cover, and the sliding member is limited by two vertical side walls of the self-locking portion to move in the extension direction of the sliding portion after the sliding member slips into the self-locking portion along the sliding portion. The whole operation is simple, laborsaving and smooth, and under the condition that the top cover is opened, when the vehicle is driven to a bumpy road, the top cover can be firmly self-locked without jitter and noise or the like.

Description

technical field [0001] The invention relates to the field of vehicle roof accessories, in particular to a self-locking vehicle roof. Background technique [0002] The openable method of the top cover of the cab in the prior art all utilizes gas springs to link the opening and closing of the top cover of the cab, mainly relying on the self-telescopic structure of the gas spring to open or close the top cover. The barrel end of the gas spring is fixed on the cab frame, and the sliding rod end of the gas spring is connected to the top cover to realize opening and closing. [0003] The above-mentioned shortcoming of using prior art is: [0004] 1. There are strict requirements on the compression force of the gas spring (the opening and closing operation is laborious when the single compression is too large, and the top cover swings frequently when it is too small); [0005] 2. The installation space takes up a lot, and it is difficult to find a suitable place for installation;...

AI Technical Summary

Problems solved by technology

[0004] 1. There are strict requirements on the compression force of the gas spring (the opening and closing operation is laborious when the single compression is too large, and the top cover swings frequently when it is too small);

[0005] 2. The installation space takes up a lot, and it is difficult to find a suitable place for installation;

[0006] 3. High failure rate and not durable

Therefore, when the force arm of the gas spring is long, due to the weight of the top cover, the top cover shakes a lot when driving, which is easy to damage the top cover and the fatigue vibration of the gas spring causes its own oil leakage and failure.

Using this structure has high failure rate, low service life, and difficult operation
