The vehicle comprises a front bumper bracket with a plurality of cylindrical sinking portions, and the buffer device is mounted in the sinking portions, is of an integral structure and comprises an adjustable type buffer block, a buffer block support receiving the adjustable type buffer block and a supporting base connected to the buffer block support; and the supporting base is supported on the bottom walls of the sinking portions, and the buffer block support is fixed to the side walls of the sinking portions in a buckle fit manner.
Description
Technical field
The present invention and a kind of damping device for hood of vehicle, particularly relate to a kind of damping device for hood of vehicle be arranged on front bumper.
Background technique
In existing vehicle, as depicted in figs. 1 and 2, the engine hood 1 of vehicle lockably joins on the front bumper bracket 2 of vehicle, front bumper bracket 2 top surface on outstanding buffer stopper 3 is installed, for cushioning the impact of engine hood to front bumper bracket 2 when engine hood is closed thus preventing damage and the distortion of engine hood or front bumper bracket.But, because the impact force fallen when engine hood is closed sometimes is excessive, the cushioning effect that the existing buffer stopper 3 directly given prominence to from the top surface of front bumper bracket provides is not enough and the supporting structure strength deficiency of buffer stopper 3 to bear excessive impact force, therefore can cause engine hood or front bumper bracket infringement or distortion.
Summary of the invention
The technical problem that will solve of the present invention overcomes the defect existed in above-mentioned prior art, proposes a kind of damping device for hood of vehicle, has the simple and high bearing strength of structure and cushioning effect, be significantly improved engine hood overshoot.
According to an aspect of the present invention, propose a kind of damping device of the engine hood for vehicle, described vehicle comprises the front bumper bracket with multiple sunk part, described damping device is arranged in described sunk part, and described damping device structure all-in-one-piece structure also comprises: adjustable buffer stopper; Receive the buffer stopper support of described adjustable buffer stopper; Be connected to the base for supporting of described buffer stopper support; Wherein support plinth is supported on the diapire of described sunk part of tubular, and described buffer stopper support is by being buckled to fix on the sidewall of described sunk part.
Preferably, described adjustable buffer stopper comprises the screw axis with cushioned head and the sleeve receiving described screw axis, screw axis and sleeve have screw thread, screw axis and sleeve are by spiral motion each other, screw axis is moved along axis relative to sleeve, thus adjustable buffer stopper can regulate the clearance surface difference of engine hood and bumper holder, headlight, beater or beat-up.
Preferably, the outer wall of described buffer stopper support arranges multiple projection, the multiple opening buckles on the sidewall of multiple projection and sunk part mesh together, thus are fixed on sunk part by damping device.
Preferably, described multiple sunk part comprises two sunk parts of the top surface both sides being arranged on described front bumper bracket.
According to a further aspect in the invention, propose a kind of motor vehicle, comprise the damping device of the above-mentioned engine hood for vehicle.

Embodiment
As shown in Figure 2, the both sides of the top surface of the both sides of the front bumper bracket 2 of vehicle are provided with sunk part 4, and the concrete structure of sunk part 4 and shape are as shown in Figure 3 and Figure 4.
According to one embodiment of present invention, the sunk part 4 that the damping device 5 cushioned engine hood 2 is arranged on the top surface of the front bumper bracket 2 shown in Fig. 2, Fig. 3 and Fig. 4 is inner.Sunk part 4 has the shape of tubular substantially, and the top of the sidewall of the sunk part 4 of tubular is provided with multiple opening 41.At sunk part 4 inside fixed installation damping device 5.Damping device 5 comprises adjustable buffer stopper 6, buffer stopper support 8 and base for supporting 7, specifically as shown in Figure 5.As shown in Figure 6, adjustable buffer stopper 6 comprises the screw axis 9 with cushioned head and the sleeve 10 receiving this screw axis 9, screw axis 9 has outside thread, sleeve 10 has cooperation internal thread, screw axis 9 and sleeve 10, by spiral motion each other, make screw axis 9 relative to sleeve 10 along axial-movement, thus adjustable buffer stopper 6 can regulate engine hood 1 and bumper holder 2, headlight, the clearance surface difference of beater or beat-up.Sleeve 10 is connected to by being clasped on buffer stopper support 8 in the inside of buffer stopper support 8, support that base 7 is fixed together with it in the below of buffer stopper support 8, adjustable like this buffer stopper 6, buffer stopper support 8 and base for supporting 7 can be assembled into the damping device 5 of integrative-structure.The base for supporting 7 of damping device 5 is bearing on the diapire of sunk part 4, the outer wall of the buffer stopper support 8 of damping device in addition arranges multiple protruding 81, together with multiple protruding 81 multiple opening 41 snap into engagement on the sidewall of sunk part 4, thus damping device 5 is firm in being fixed on sunk part 4 further.So damping device 5 according to the present invention can be fixedly mounted in the sunk part on the top surface of the front bumper of vehicle, the structure with high support strength and one is simple, the excessive impact force of the whereabouts of engine hood can be born, and engine hood overshoot is significantly improved, therefore can not cause engine hood or front bumper bracket infringement or be out of shape, in addition can also engine hood 1 and bumper holder 2 according to damping device 5 of the present invention, headlight, the clearance surface difference of beater or beat-up.
Although show relative to embodiment and describe the present invention, it will be understood by those of skill in the art that and can not depart from the scope of the present invention and make a variety of changes and improve.
