Embodiment 1

[0021] Embodiment 1: As the vehicle deforms after a crash occurs, it may even trap people in the driver's seat or the passenger's seat, and rescue is difficult, which can easily cause life threats. However, the shape memory alloy is used in the steel beam of the car's driver's seat or the co-pilot, and the shape memory alloy is hollow inside and equipped with a heating device. Then, after a crash, the heating device heats up to its deformation temperature. The shape memory alloy can be restored to its original shape, which can better rescue the trapped. Shape memory alloys can be selected from Ni-Ti alloys, Cu-Al alloys, Cu-Zn-Al alloys, Cu-Zn-Sn alloys, Cu-Zn-Si alloys, Cu-Sn alloys with a deformation temperature in the range of 80-200℃ , Cu-Zn-Ga alloy, In-Ti alloy, Au-Cu-Zn alloy, NiAl alloy, Fe-Pt alloy, Ti-Ni alloy, Ti-Ni-Pd alloy, Ti-Nb alloy, U-Nb alloy and Fe-Mn-Si alloy, etc. In order to save costs, it can also be arranged only at the corners or spaced apart at the c...

Embodiment 2

[0022] Embodiment two: such as figure 1 As shown, on the basis of Example 1, the heating device includes quicklime 3 and an aqueous solution (the mass ratio of quicklime to aqueous solution is 1:3-5), if the pH of the aqueous solution <7, it will release more heat when reacting with quicklime 3, which can be selected according to needs. The aqueous solution is set in the sealed container 2. When a crash occurs, the sealed container 2 is broken due to the deformation and extrusion of the vehicle (the sealed container is made of brittle materials such as glass and ceramics), and the aqueous or acid solution flows out and mixes with quicklime 3. The heat generated by the reaction heats the shape memory alloy 1 to restore the shape of the shape memory alloy 1 to the shape before the collision, and prevents the driver or passenger seat from being trapped.

Embodiment 3

[0023] Embodiment three: such as figure 2 Said, on the basis of the second embodiment, the heating device also includes a solid acid (the solid acid can be trichloroacetic acid, periodic acid, dinitrobenzoic acid, ethylenediaminetetraacetic acid, p-toluenesulfonic acid, p-toluenesulfonic acid, Hydroxybenzenesulfonic acid, phosphorous acid, heteropoly acid and solid super acid, etc.; it can also be natural clay (such as bentonite, montmorillonite, kaolin, etc.), embodied acid (such as embodied in SiO 2 , Phosphoric acid, sulfuric acid, boric acid, etc. on diatomaceous earth), oxides (such as alumina, zirconia, titanium oxide, etc.), mixed oxides (such as SiO2-Al2O3, ZrO2-SiO2), zeolite, resin (cation exchange resin) Such as polystyrene sulfonic acid type resin), activated carbon, etc.) 4, the solid acid 4 can be separately arranged inside the shape memory alloy 1 (not in contact with quicklime) or adsorbed inside the porous material, when the aqueous solution (PH <≤7) When flowin...

Abstract

The invention discloses an automobile deformation recovery device. The automobile deformation recovery device is characterized in that the recovery device is made of shape memory alloy materials; anda shape memory alloy is hollow, and a heating device is arranged in the shape memory alloy. The automobile deformation recovery device can automatically recover into the original shape after an automobile crash accident occurs, thus damage to persons on a driver seat and a passenger seat is reduced, and safety performance is better.

Description

【Technical Field】 [0001] The invention relates to the technical field of automobile safety, in particular to an automobile deformation recovery device. 【Background technique】 [0002] With the increase in car ownership and frequent traffic accidents, car safety issues have become a focal issue. Studies have shown that the probability of a frontal collision, a side collision and a rear collision of a car is 39%, 38%, and 23%, respectively. When a car collides, the passengers in the driver's seat and the passenger's seat will be trapped in their seats and cannot move, which can easily cause serious life threats. Therefore, it is necessary to design a device that can self-recover to the original state after a crash occurs to improve the safety performance of the car. [Content of the invention] [0003] In view of the above problems, the present invention provides an automobile deformation recovery device. [0004] The present invention is achieved through the following technical sol...
