In the thrust block device that above-described embodiment provides, as shown in Figure 2, after damping module 123 is fixed on the end-stopping plate 122, and when not being fixed on the front end-stopping plate 121, can be fixed with sleeve 124 on the front end-stopping plate 121, sleeve 124 can be set on the end of rear end-stopping plate 122 of deviating from of damping module 123, thereby sleeve 124 can play position-limiting action to the sheathed damping module 123 thereon of an end, prevent that damping module 123 is in the process of crumple, bend along the direction that is parallel to the front and back ends baffle plate, thereby prevent the crumple degradation.
In the thrust block device that above-described embodiment provides, an end that deviates from rear end-stopping plate 122 of damping module 123 and front end-stopping plate 121 interval distance to a declared goal.When rear end-stopping plate 122 stressed 121 directions of end-stopping plate forward motion, a period of time of need to advancing could contact with damping module 123 through behind this distance to a declared goal.The size of the end that deviates from rear end-stopping plate 121 by adjusting damping module 123 and the distance to a declared goal at front end-stopping plate 121 intervals, can control from the rear 122 stressed times to rear end-stopping plate 122 and damping module 123 of end-stopping plate, thereby can control the 123 compressed times of damping module, and then the time of control thrust block 11 ejections.
Fig. 3 shows the structure of another kind of thrust block device, need to prove, identical structure has identical Reference numeral among Fig. 1 to Fig. 3.
Fig. 3 and Fig. 1 difference are, damping module 123 in the thrust block device shown in Figure 3 is fixed on front end-stopping plate 121 and the rear end-stopping plate 122, and the damping module 123 in the thrust block device shown in Figure 1 is fixed on the front end-stopping plate 121, is not fixed on the rear end-stopping plate 122.The difference of Fig. 2 and Fig. 3 is, thrust block device shown in Figure 2 is fixed on the rear end-stopping plate 122, is not fixed on the front end-stopping plate 121.
In the thrust block device that above-described embodiment provides, damping module 123 can be four, and sleeve 124 can be four, and damping module 123 is corresponding one by one with sleeve 124.
Certainly damping module 123 and with its other quantity that sleeve 124 quantity also can be known to those skilled in the art one to one, to reach better crumple energy-absorbing effect.
In the thrust block device that the embodiment of the invention provides, damping module 123 can be damper tube, and the damper tube damping capacity is good, can bring into play preferably the crumple energy-absorbing function, and the damping capacity of damper tube is relevant with its damping parameter.Such as the diameter of damper tube, thickness, material etc.The damper tube of identical material, same diameter, its thickness is more thick more to be difficult to compressedly, and damping capacity is poorer; The damper tube of identical material, same thickness, its diameter is more large more to be difficult to compressedly, and damping capacity is poorer.
The embodiment of the invention also provides a kind of car door, comprises the thrust block device that above-described embodiment is described.
In the car door that the embodiment of the invention provides, because the thrust block device that has adopted above-described embodiment to describe, the ability that the thrust block device absorbs collision energy is higher, the dummy is not easy injured.And, be collided from arrangements for automotive doors shorter to thrust block ejection required time, so that the dummy can in time be pushed open.
The above; be the specific embodiment of the present invention only, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
