The invention relates to the technical field of road safety protection, and discloses a vehicle wrapping spiral type damping buffer device which comprises a wrapping mechanism, the wrapping mechanism comprises a head-on collision plate, a base and a plurality of hydraulic tappets arranged between the head-on collision plate and the base, a hydraulic cavity is formed in the base, and the hydraulic tappets are communicated with the hydraulic cavity; the first-stage buffering mechanism comprises a buffering box and a liquid storage tank arranged in the buffering box, the buffering box is connected to the base, and the base can extrude the liquid storage tank and the buffering box to enable the base to be in a floating state; according to the secondary buffering mechanism, one end of the screw rod is connected with the buffering box, the rotating disc is connected to the rotating wheel through a first elastic piece, the rotating disc and the screw rod are eccentrically arranged, and the two ends of a second elastic piece are connected with the rotating disc and the mounting base respectively. The damping and buffering device has the advantages that the damping and buffering device can wrap the front end of a rear vehicle, the wrapping mechanism is in a floating state through oil liquid, the damping effect is good, and the buffering effect is further improved in cooperation with a secondary buffering mechanism.

    本发明涉及道路安全防护技术领域,公开一种车用包裹螺旋型减震缓冲装置,包括有:包裹机构,包裹机构包括迎撞板、底座和设置在迎撞板与底座之间的多个液压挺柱,底座中设有液压腔,液压挺柱与液压腔相连通;一级缓冲机构,包括缓冲箱和设置在缓冲箱中的储液罐,缓冲箱连接在底座上,底座可挤压储液罐和缓冲箱,使底座处于浮动状态;二级缓冲机构,螺旋杆的一端与缓冲箱连接,转盘通过第一弹性件连接在旋转轮上,且转盘与螺旋杆呈偏心设置,第二弹性件的两端分别与转盘和安装座相连。本发明的优点在于,该减震缓冲装置可对后车前端进行包裹,且通过油液使包裹机构处于浮动状态,减震效果好,并配合二级缓冲机构,进一步提升缓冲效果。
