The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 3 and Fig. 4 are front view and the birds-eye view of the cliding door shock absorber of the utility model one embodiment.As shown in Figure 3, Figure 4, the cliding door shock absorber of the utility model one embodiment comprises bumper 1, buffing pad 2 and spring 3, described buffing pad 2 has the first adapter plate 21 and the second adapter plate 22 being parallel to each other, on described the first adapter plate 21, there is opening, the first end of described spring 3 is fixed on described the second adapter plate 22, the rear end of described bumper 1 is located in described opening, and is connected with the second end of described spring 3.
Particularly, described buffing pad 2 can be provided with for inside the U-shaped plate of baffle plate, and described baffle plate is vertically set between two sides of described U-shaped plate, and the closed end of described U-shaped plate forms described the first adapter plate 21, and described baffle plate forms described the second adapter plate 22.The cliding door shock absorber of the present embodiment is by arranging spring 3, while making car door opening after collision buffering gear 1, the formed impact of car door is cushioned by the spring 3 being connected with bumper 1, thereby can effectively avoid long-term shock of car door to cause the destruction to side wall.
