Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile engine hood. Background Art

[0002] Although the automobile industry in our country started relatively late, it has developed relatively rapidly in the past ten years or so. In particular, its rise in recent years has put pressure on many joint-venture cars. Moreover, this has also prompted many Chinese people to seriously consider domestic cars and even support domestic cars. Such a trend is indeed a great blessing for domestic cars. Now, when the engine hood of a domestic car is opened, the rear compartment is very clean, and the engine is sealed very cleanly with a hood. However, when it is necessary to repair the inside of the engine, the whole hood needs to be disassembled, which is very inconvenient and troublesome for maintenance personnel. For this reason, there is a publicly disclosed technology in the market that proposes an aesthetic hood for an automobile engine compartment, which relates to the technical field of automobile parts and includes a hood. A cover plate is arranged inside the hood. A fixing groove is fixedly opened on one side of the top of the hood close to the cover plate. A connecting block is placed in the inner cavity of the fixing groove. This publicly disclosed technology states that: for this aesthetic hood for an automobile engine compartment, by providing a connecting block, an unlocking groove and a clamping post, when it is necessary to repair the inside of the engine compartment, the unlocking block is moved towards the moving groove direction, pushing the moving block to move into the moving groove. The unlocking block pulls the rope groove, and the rope groove drives the clamping post to slide into the clamping groove, so that one end of the clamping post is disengaged from the clamping of the clamping groove. At this time, under the action of the ejecting spring, the clamping groove is pushed to move upward along the inside of the fixing groove, and the cover plate is taken out. Then the maintenance personnel repair the inside of the engine compartment, which facilitates the maintenance personnel to disassemble and install the cover plate;

[0003] However, the above publicly disclosed technology is to provide multiple separable cover plates on the hood. When local maintenance is required, the cover plates are removed. When overall maintenance is required, multiple cover plates still need to be removed, which has no obvious improvement compared with removing the hood by unscrewing multiple screws in the traditional technology, and the process is still relatively cumbersome. Moreover, the way of fixing by snap pins is difficult to play a completely fixed role in actual application, and the connection part is prone to vibration and generate abnormal noise, increasing the noise. Therefore, it is necessary to make further improvements. Summary of the Utility Model
