In order to solve the technical matters of above-mentioned existence, the utility model has adopted following scheme:
A kind of collision-prevention device of vehicle door, it is characterized in that: comprise inner plate of car door, rubber spring plate, spring, diaphragm spring, rubber coating and door skin, described rubber spring plate is fixed on inner plate of car door, described diaphragm spring is fixed on rubber spring plate, described spring is fixed between diaphragm spring and rubber spring plate, and described rubber coating is embedded in the separation finger of diaphragm spring and is fixed on door skin.
Further, described spring is compounded rubber spring, and described compounded rubber spring is made up of metal coil spring and the polysulphide rubbers that is wrapped in metal coil spring surface.
Further, described rubber spring intralamellar part arranges multiple groove structures.
Further, the cross section of described groove is rhombus.
Further, described multiple groove is parallel to each other.
Further, the quantity of described spring is not less than three and distribute with symmetry dispersing mode.
Further, described spring is connected with diaphragm spring and rubber spring plate respectively by metal-to-metal adhesive water.
Further, the connection mode between described diaphragm spring and rubber spring plate is for welding, willow connect, screw is connected or metal glue connects.
In the time that arrangements for automotive doors is collided, first door skin contacts rubber coating, rubber coating can be by the load-division after door skin side collision to diaphragm spring, and then prevent that arrangements for automotive doors local pressure is excessive, diaphragm spring absorbs part energy, load is by the separation finger transmission of diaphragm spring simultaneously, in the time that separation finger moves and touches spring to inner plate of car door direction, absorption portion energy again after spring stress distortion, when after separation finger contact rubber spring plate, rubber spring plate also can absorb part energy.In addition, increase and decrease by the quantity to spring described in the utility model, can meet the not performance requriements of syn-collision to arrangements for automotive doors.
Collision-prevention device of vehicle door described in the utility model has following beneficial effect:
(1) simple in structure, lightweight, the low cost of manufacture of the utility model collision-prevention device of vehicle door, the advantage such as practical life is long.
(2) the distinctive structure of the utility model collision-prevention device of vehicle door, can be in automobile side bumps, car door has good load bang path, utilize multiple parts to absorb energy, improve the resistance to bending of car door, the safety of car door improves, and passenger injures expectation value and reduces, and can regulate the particular/special requirement of different arrangements for automotive doors to safety performance.

Detailed description of the invention
Below in conjunction with accompanying drawing 1 to 4, the utility model is described further:
With reference to Fig. 1, collision-prevention device of vehicle door described in the utility model, comprises inner plate of car door 1, rubber spring plate 2, spring 5, diaphragm spring 4, rubber coating 3 and door skin.Described rubber spring plate 2 by welding, willow connects, screw or metal-to-metal adhesive hydropexis be on inner plate of car door.Described diaphragm spring 4 by welding, willow connects, screw or metal-to-metal adhesive hydropexis be on rubber spring plate 2.Described spring 5 is connected with diaphragm spring 4 and rubber spring plate 2 respectively by metal-to-metal adhesive water, and spring 5 is selected plain metal spring or compounded rubber spring.Described rubber coating 3 is embedded in the separation finger of diaphragm spring 4 and is fixed on door skin.In the time that arrangements for automotive doors is collided, first door skin contacts rubber coating 3, rubber coating 3 can be by the load-division after door skin side collision to diaphragm spring 4, and then prevent that arrangements for automotive doors local pressure is excessive, diaphragm spring 4 absorbs part energy, load is by the separation finger transmission of diaphragm spring 4 simultaneously, in the time that separation finger touches spring 5 to inner plate of car door 1 direction motion, absorption portion energy again after described spring 5 stress deformations, when after separation finger contact rubber spring plate 2, rubber spring plate 2 also can absorb part energy.In automobile side bumps, car door has good load bang path, utilizes diaphragm spring, spring and rubber spring plate jointly to absorb energy, has improved the resistance to bending of car door, and the safety of car door improves, and passenger injures expectation value and reduces.Also there is the advantages such as simple in structure, lightweight, low cost of manufacture, practical life are long simultaneously.
