Description

Special hydrogenation flap of hydrogen fuel car

Technical Field

The utility model relates to a hydrogen energy vehicle accessory, in particular to a hydrogenation cover special for a hydrogen fuel vehicle.

Background

The existing hydrogen energy vehicle does not have a special hydrogenation flap, and is a general flap which adopts fuel oil or CNG and LNG, a hydrogenation panel is fixed in a form of a welding bracket on the whole vehicle body, a certain fit gap exists between the hydrogenation panel and the flap, the tightness is poor, rainwater is easy to infiltrate from the gap, and thus the overall tightness is insufficient, and the use is affected.

Disclosure of Invention

In view of the defects of the existing hydrogen fuel vehicle, the technical problems to be solved by the utility model are as follows: provides a hydrogenation special-purpose opening cover with better sealing performance.

In order to achieve the above object, according to one aspect of the present utility model, the present utility model is achieved by the following technical means: a hydrogen fuel vehicle dedicated hydrogenation flap comprising: the hydrogenation device comprises an outer frame, wherein an inner frame body with a punching side opening is formed in the outer frame in a punching mode, a hydrogenation panel is fixed on the bottom surface of the inner frame body through bolts, the opening side of the inner frame body is tightly closed by an outer cover in a movable mode, and the outer frame is connected with an outer skin of a vehicle body in a full-welded mode.

Further, the hydrogenation panel is fixed to the inner face frame by bolts. The design structure is simple and reasonable, and various types of hydrogenation panels are convenient to fix.

Further, one side of the outer cover is fixed with the outer frame through a hinge, the other side of the outer cover is fixed through a lock catch and a pull buckle, and the lock catch and the pull buckle are respectively arranged on the outer cover and the inner frame body. The design is convenient to install and fix, and is convenient to open simultaneously.

Further, the hinge, the lock catch and the pull buckle are all fixed through spot welding.

Further, a sealing rubber strip for sealing the opening side of the inner face frame body is arranged on the outer cover. The above design is to further improve the sealability.

Compared with the prior art, the utility model has the advantages that: the inner frame body is used as the mounting surface of the hydrogenation panel, welding of an original vehicle body support can be canceled, workload and vehicle body dead weight are reduced, the assembly welding structure after stamping forming enables the flap to have excellent sealing performance and attractive appearance, the flap and the vehicle body are integrated through full welding and vehicle body outer skin connection, the appearance integrity of the whole vehicle is improved, the whole vehicle is more attractive, and when the flap is flushed by rain, the sealing effect can be completely realized by the sealing rubber strip, and rainwater is prevented from entering.

Drawings
