Description
Technical Field
The invention belongs to the field of automobiles, and particularly relates to an automobile anti-disassembly structure and an assembly method thereof.
Background
With the development of society and the progress of science and technology, automobiles are becoming an indispensable transportation means in people's daily lives. In the use process of automobiles, the safety of the automobile door is particularly important, and particularly, for special vehicles which execute special tasks, such as police riot vehicles, banknote vehicles, ambulances and the like, higher requirements are put on the anti-dismantling performance of the automobile door. The reliability of the mounting structure of the hinge, which is a key component for connecting the vehicle body and the vehicle door, directly influences the safety of the vehicle door and the overall protective performance of the vehicle.
At present, a common automobile hinge is usually installed on the outer side of an automobile body by adopting a bolt, and the structure is common in the traditional automobile design and has certain stability and economy. However, this conventional mounting structure has significant security vulnerabilities in the face of some special scenarios and requirements. Although parts such as a fender are reinstalled on the outside of the vehicle body to conceal the hinge during subsequent assembly of a part of the vehicle, the safety of such concealing is not high. The fender of an automobile is usually made of a thin steel plate or engineering plastic, and the strength and the damage resistance of the material are relatively weak, so that the fender is easily damaged by lawless persons through violent measures. Once the fender is damaged, the mounting bolts on the hinge are directly exposed, and at the moment, the hinge mounting bolts can be easily detached by using common tools such as a spanner, a screwdriver and the like, so that the door can be opened, and the door anti-detachment performance obviously cannot meet the requirement that the hinge cannot be detached or damaged within 10 minutes under the condition of combining a mechanical hand tool with an 8-pound hammer in GA 668 police anti-riot vehicle general technical condition.
In practical applications, the easy detachability of such hinges presents numerous safety hazards to the vehicle. For a common passenger car, a car owner can face the problems that property in the car is stolen, the car is illegally invaded, and the like. For special vehicles, such as police antiriot vehicles and banknote-transporting vehicles, the consequence that the vehicle door is easily opened is more serious, and the life safety of personnel in the vehicle and the safety of important materials carried by the vehicle can be directly threatened.
In the prior art, although there have been some improvements to door tamper protection, these have often had certain limitations. Some vehicles employ special locks or encryption devices to prevent the door from being easily opened, but these locks generally only reinforce the handle or inner latch portion of the door, and do not provide significant protection to the key portion of the hinge. Still other vehicles attempt to improve safety by increasing the thickness of the door or using high strength materials, however, these methods not only increase the weight of the vehicle, resulting in increased fuel consumption, but also affect the design aesthetics and practicality of the vehicle to some extent, and also greatly increase the manufacturing cost of the vehicle, which is disadvantageous for large-scale popularization and application.
In summary, the anti-disassembly performance of the automobile hinge in the prior art has obvious defects, cannot meet the increasing vehicle safety requirements, and particularly has extremely weak protection capability when facing violent disassembly tools.
