The invention discloses an automobile back door hydraulic buffering structure and an automobile. The automobile back door hydraulic buffering structure comprises a flow channel assembly, a rubber buffering block and an elastic leather cup. An upper liquid chamber is arranged in the rubber buffer block; a lower liquid chamber is arranged in the elastic leather cup; the flow channel assembly is arranged between the upper liquid chamber and the lower liquid chamber, the flow channel assembly comprises a flow channel body with a flow channel and a rubber decoupling film, a vertically-through through hole is formed in the middle of the flow channel body, and the rubber decoupling film is arranged at the through hole to isolate the upper liquid chamber from the lower liquid chamber; the runner body is further provided with a first runner opening used for communicating the upper liquid chamber with the runner and a second runner opening used for communicating the lower liquid chamber with the runner. Liquid is contained in the upper liquid chamber and the lower liquid chamber, and the liquid can flow back between the upper liquid chamber and the lower liquid chamber in a reciprocating mode through the first flow channel opening, the flow channel and the second flow channel opening. While the buffering performance is guaranteed, the large rigidity and damping are provided in the low-frequency range, and large-amplitude vibration generated by an engine or a road surface can be effectively attenuated.
本发明公开了一种汽车背门液压缓冲结构及车辆,包括流道组件、橡胶缓冲块和弹性皮碗;橡胶缓冲块中具有上液室;弹性皮碗中具有下液室;流道组件设置在上液室和下液室之间,流道组件包括具有流道的流道本体和橡胶解耦膜,流道本体的中间设置上下贯通的通孔,橡胶解耦膜设置在该通孔处,以使上液室和下液室隔离;流道本体上还设有用于将上液室和流道连通的第一流道口,以及将下液室和流道连通的第二流道口;上液室和下液室内装有液体,且液体能通过第一流道口、流道和第二流道口在上液室和下液室之间往复回流。本发明在保证缓冲性能的同时,在低频范围内提供较大刚度和阻尼,能够有效衰减发动机或路面产生的大幅值振动。
