The invention discloses an escape assisting device, a vehicle door structure and a vehicle, and relates to the technical field of vehicles, the escape assisting device comprises a shell and a spray head, the shell is provided with a containing cavity, and a fire extinguishing agent is stored in the containing cavity; and at least one spray head is arranged, the spray head is used for being arranged in the area, located between the battery pack and the vehicle door body, of the bottom of the vehicle, the spray head communicates with the containing cavity, an outlet of the spray head faces downwards, and the spray head is used for spraying the fire extinguishing agent downwards. According to the technical scheme, the spray head is arranged in the area, located between the battery pack and the vehicle door body, of the bottom of the vehicle, when the battery pack of the vehicle is on fire, the fire extinguishing agent stored in the containing cavity is sprayed downwards through the spray head, flame is prevented from being spread towards the vehicle door body, and the fire extinguishing effect is improved. The possibility that flames inrush into a vehicle due to air pressure change when the door is opened is reduced, and the safety of escape personnel is guaranteed.
本发明公开了一种逃生辅助装置、车门结构以及车辆,涉及车辆技术领域,其中,逃生辅助装置包括壳体和喷头,所述壳体具有容纳腔,所述容纳腔内存储有灭火剂;所述喷头至少设置有一个,所述喷头用以设置在车辆底部位于电池包与车门主体之间的区域,所述喷头与所述容纳腔连通且出口朝下设置,用以朝下喷淋所述灭火剂。在本发明的技术方案中,通过将所述喷头设置在车辆底部位于电池包与车门主体之间的区域,在车辆的电池包起火时,通过所述喷头将储存在所述容纳腔内的灭火剂朝下喷淋,阻隔火焰朝车门主体的传播,减小在开门时火焰由于气压变化而涌入车辆内部的可能性,保证逃生人员的安全性。
