Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 2 and 3, the utility model provides a bonnet 1 rear end seal structure, it is located the vehicle front portion in phase, it includes bonnet 1, tank apron 2 and sealing strip 3, and tank apron 2 is located the below of the rear end of bonnet 1, has the sealed face of subtend setting respectively at bonnet 1 and tank apron 2, and wherein, the sealed face 12a of bonnet 1 extends along the rear end edge of bonnet 1 along the direction of 1a, and sealing strip 3 fixes on this sealed face 12 a.

When the engine cover 1 is turned and closed by taking the hinge point 1b as a center, the other end of the sealing strip 3 is attached to the sealing surface 2a of the water tank cover plate 2 so as to shield a gap between the engine cover 1 and the water tank cover plate 2, and meanwhile, the rigidity, the strength and the mode of the engine cover 1 are increased by the characteristic, so that when a vehicle runs, the vibration of the engine cover 1 is transmitted to the water tank cover plate 2 (namely, a vehicle body) through the sealing strip 3, and the problem that the rigidity and the mode of the engine cover 1 formed in a stamping mode are difficult to improve in the prior art is solved.

This 1 rear end seal structure of bonnet, through set up in the sealing strip 3 that 2 laminating mutually of water tank apron at 1 rear end of bonnet, sheltered from the clearance between bonnet 1 and the water tank apron 2 to improve the rigidity and the mode of water tank apron 2, alleviated the problem that 1 vibrations of bonnet and produced the noise, effectively promoted user's use and experienced.

It should be noted that, although the weather strip 3 is fixed to the sealing surface 12a on the engine cover 1 side in the present embodiment, the weather strip 3 may be fixed to the sealing surface 2a on the water tank lid 2 side in the same manner in other embodiments, and the same technical effects can be achieved.
