Abstract
The invention relates to a buffering element of a vehicle door. The buffering element of the vehicle door comprises a buffering body and a clamping head. The buffering body is a cone-shaped cylinder body, the clamping head is connected with the large-diameter end of the buffering body, and the end face of the large-diameter end of the buffering body is provided with at least one circle of a sealing lip around the axis of the clamping head. The buffering element is convenient to install and has strong waterproof and shock-absorption functions.
Description
Technical field
The present invention relates to the automatic buffer parts, be specially a kind of car door buffer component.
Background technology
Along with the development of automotive engineering, people are more and more higher for the requirement of car comfort.Current arrangements for automotive doors suffered jerk when buffer stopper being installed on the car door panel beating alleviating closing of the door mostly, and solving in the Vehicle Driving Cycle process, collide between car door and body side wall and produce the problem of abnormal sound.Existing modal buffer component as shown in Figure 4,5, it comprises the clamping joint of integrated injection molding and the buffer body of tapered column structure, described buffer component is fixed on the car door panel beating by clamping joint, when closing of the door, the outside path end face of vehicle body contact buffer body, utilize the plastic strain of buffer body to carry out impact-absorbing.CN201614829U also discloses the buffer component similar to said structure in addition, but existing buffer component on being arranged on the car door panel beating after, because inboard bigger diameter end face and the car door panel beating of buffer body do not have waterproofing design, therefore rainwater easily flows in car door through the inboard bigger diameter end face of buffer body and the installing hole of gap on the car door panel beating between car door panel beating outer wall, and the clamping joint of existing buffer component is an overall structure, when mounted clamping joint is pushed in the installing hole of car door panel beating, the inside plastic shrinkage by clamping joint, thereby clamping joint is sticked in the installing hole of car door panel beating, install more difficult, fit dimension to clamping joint and car door panel beating installing hole is had relatively high expectations.
Summary of the invention
The object of the present invention is to provide a kind of easy for installation and there is the car door buffer component of stronger water-proof function and damping effect.
Car door buffer component of the present invention, comprise buffer body and clamping joint, and described buffer body is conical cylinder, and described clamping joint is connected with the bigger diameter end of buffer body, on the bigger diameter end end face of described buffer body, around the clamping joint axis, is provided with at least one circle sealing lip limit.
Further, described sealing lip limit is horn-like.
Further, on described clamping joint, along its axis, be arranged with two wedge shape card bases, described two wedge shape card bases have elasticity, can inwardly close up contraction.
Further, miner diameter end at described buffer body offers counterbore along the buffer body axis, and the openend of described counterbore has tapering, and on buffer body, the purpose of perforate is to improve the deflection of buffer body when being subject to impacting, with impact-absorbing load, and the sound quality can improve closing of the door the time.
Further, described clamping joint is made by polypropylene (PP) or polyethylene (PE) material, and described buffer body is made by thermoplastic elastomer (TPE) (TPE) material.
Further, offer the hole clipping that is positioned at the sealing lip limit on the bigger diameter end of described buffer body, described clamping joint is fixed on this hole clipping, buffer body in existing buffer component and clamping joint are all same material integrated injection moldings, and while adopting different materials, separately injection mo(u)lding is comparatively simple, when buffer body and clamping joint are assembled into to one, first heated, make its expanded by heating, then clamping joint is compressed into to described hole clipping, both are tightened securely, an end that is clamping joint is connected with buffer body, and the other end is connected with the car door panel beating.
Beneficial effect of the present invention is: 1, by the sealing lip limit is set on buffer body; while making this buffer component be arranged on car door; described sealing lip limit can be pressed on the car door panel beating, thereby effectively prevents that rainwater from flowing in car door, prevents the car door corrosion and protect the car door circuit.2, the clamping joint on this buffer component adopts card base and car door to connect and fix, because described wedge shape card base has the activity inwardly closed up, therefore this buffer component is lighter with the installation of car door panel beating.3, on buffer body with the design of the counterbore of tapering, make the distortion energy-absorbing effect of this buffer component better, and can improve the sound quality of closing the door.4, buffer body and clamping joint adopt unlike material to make, and not only can guarantee buffer body distortion energy-absorbing, also can make clamping joint have relatively high hardness, intensity, thereby guarantee the bonding strength of clamping joint and car door panel beating.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further elaborated:
As Fig. 1, car door buffer component shown in Fig. 2, comprise the buffer body 1 of being made by polypropylene and the clamping joint 2 of being made by thermoplastic elastic material, described buffer body 1 is conical cylinder, miner diameter end at buffer body 1 offers counterbore 12 along buffer body 1 axis, the openend of described counterbore 12 has tapering, being provided with a circle around clamping joint 2 axis on the bigger diameter end end face of buffer body 1 extends out and is trumpet-shaped sealing lip limit 11, also offer the hole clipping 13 that is positioned at a described circle sealing lip limit 11 on the bigger diameter end of buffer body 1, described clamping joint 2 is fixed on this hole clipping, be arranged with two wedge shape card bases 21 along its axis on described clamping joint 2.
Above-mentioned buffer body 1 also can be made by polythene material.
As shown in Figure 3, described car door buffer component is fixed on car door panel beating 3 by two wedge shape card bases 21 on clamping joint 2, and the sealing lip limit 11 on described buffer body 1 is pressed on car door panel beating 3, effectively prevents that rainwater from flowing in car door.
