Problems solved by technology

[0004] But in above-mentioned this kind of machine cover, when the machine cover is turned back to open the machine cover, since the front of the car is usually low at the front and high at the rear, it is inconvenient to open the machine cover, and due to being affected by the driving parts of the car such as the windshield, etc. The opening angle of the cover will also be limited, that is, the opening space of the cover is limited, so it is inconvenient to maintain the engine or related parts; in addition, if major maintenance such as disassembling the engine or other parts When installing components, the machine cover needs to be removed from the car, which increases the labor intensity of workers and is very inconvenient to operate

It is featured as setting said driving unit behind support bar, hinging bottom ends of support bar and driving unit separately on automobile body and connecting their top ends separately to machine cover.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a machine cover operating mechanism. Background technique [0002] In the prior art, the engine cover is arranged at the front of the automobile to cover the engine and some associated parts. Under normal circumstances, the cover is closed; when it is necessary to disassemble, repair or check the engine or related parts, the cover needs to be opened. [0003] Usually, the rear end (that is, the end close to the cab) of the machine cover is hinged on the vehicle body through a hinge device, and the front end is locked by an openable locking device. Under normal circumstances, the cover is closed and locked by the locking device so that it will not be opened automatically due to the bumping of the vehicle during the running of the vehicle. When it is necessary to open the cover, open the locking device at the front of the cover, and then lift up the cover firmly to open the cover. In ...
