Description

Technical Field

[0001] The present invention belongs to the technical field of special vehicle body accessories, and in particular, relates to a detachable explosion-proof shield-type vehicle door, a vehicle body structure and a special vehicle. Background Art

[0002] Explosion-proof vehicles generally need to carry various explosion-proof equipment, weapons, and communication equipment according to the urgency and expected scale of the mission, in order to respond to emergencies and perform tasks such as on-site control. Armored explosion-proof vehicles are usually equipped with explosion-proof shields, which play a protective, tactical, and psychological role. There are two traditional assembly forms of explosion-proof shields, both of which have certain limitations: the first is to store the explosion-proof shield inside the vehicle, which is convenient for users to take it out of the vehicle, but special space needs to be reserved for placement. Carrying too many explosion-proof shields will take up a lot of space, restricting the movement of people in the vehicle, and the size of the explosion-proof shield will be limited by the size of the space inside the vehicle and the size of the door that can be passed; the second is to install it on the outside of the vehicle, which requires a specially designed reliable assembly and fixing structure. The explosion-proof personnel can only take and use the explosion-proof shield after getting off the vehicle, which is dangerous and inconvenient for the users, and there are certain risks for the safe storage of the explosion-proof shield. Regardless of the assembly form used, whether the explosion-proof shield is stored inside the vehicle or installed outside the vehicle, it will increase the overall weight of the vehicle, affect the acceleration, braking and handling performance of the explosion-proof vehicle, make it more difficult to control during driving, and increase the risk of accidents in complex road conditions or emergency situations. Summary of the invention

[0003] The object of the present invention is to provide a detachable explosion-proof shield type vehicle door, a vehicle body structure and a special vehicle. The vehicle door is designed as a detachable explosion-proof shield type structure, and the vehicle door and the peripheral outer plate of the vehicle body are detachably fixedly connected through multiple groups of quick fixed connection vehicle body components. The vehicle door is not only a part of the vehicle body structure, but also can be quickly removed from the vehicle to be used as an explosion-proof shield, which can improve the safety of explosion-proof personnel when getting off the vehicle, increase the space inside the vehicle, reduce the weight of the whole vehicle, make the special vehicle easy to control during driving, and reduce the risk of accidents; multiple groups of quick fixed connection vehicle body components are evenly fixed on the vehicle door and the peripheral outer plate of the vehicle body at intervals, so that the connection between the vehicle door and the peripheral outer plate of the vehicle body is more stable, and when the vehicle is driving and subjected to impact, the force received can be more evenly dispersed, thereby enhancing the overall safety of the vehicle; multiple groups of quick fixed connection vehicle body components make the vehicle door and the peripheral outer plate of the vehicle body fit more closely, and can better meet the needs of vehicle use in terms of sound insulation, dustproof, waterproof and other aspects; multiple detachable explosion-proof shield type vehicle doors are opened on the peripheral outer plate of the vehicle body to disperse the flow of people getting off the vehicle, improve the speed of explosion-proof personnel getting off the vehicle, and reduce costs.
