As an important means of transportation, automobiles have entered thousands of households, and the safety performance of automobiles has also attracted increasing attention. Many new technologies are used to prevent vehicle collisions Afterwards, it will cause damage to the circle. The quality of safety performance has become an important criterion to measure the quality of automobiles. Among them, strengthening the anti-collision performance of the body and avoiding the damage to occupants caused by the deformation of the body after collision is a key indicator for improving the passive safety performance of automobiles. the

Vehicles are likely to cause injuries to drivers and passengers in offset collisions, so there are strict requirements for the safety of the front pillars of vehicles. In the prior art, because the material strength of the side wall outer panels used on the front pillars of automobiles is generally weak, the material of the upper panel reinforcement plates on the inner panels of the front pillars is generally a high-strength steel plate. The inner panel bears the frontal collision load, but due to its weak load bearing capacity, the intrusion of the front pillar is relatively large in the collision, the living space of the occupant is reduced, and the driver and occupant in the collision have a greater risk. the

Contents of the invention

The purpose of the utility model is to solve the problems mentioned above in the prior art, and propose a simple, safe and firm reinforcement structure for the front pillar of the automobile. the

The purpose of this utility model can be achieved through the following technical proposals: a reinforcement structure for a front pillar of an automobile, comprising a front pillar outer panel and a front pillar inner panel, characterized in that a front pillar outer panel and a front pillar inner panel are provided with a A reinforcement plate, forming a crash cavity between the reinforcement plate and the inner panel of the front pillar. the

This technical solution optimizes the structure of the front pillar. By setting a reinforcing plate in the outer panel and the inner panel of the front pillar, an anti-collision cavity structure is formed inside the front pillar, so that the cross-sectional structure changes and increases the safety during collision. bear the load. the

In the above-mentioned reinforcing structure of the front pillar of the automobile, the reinforcing plate protrudes toward the outer panel of the front pillar. In the technical solution, the reinforcing plate protrudes toward the outer panel of the front pillar, so that the volume of the anti-collision cavity formed between it and the inner panel of the front pillar is further increased, which can bear a larger load and enhance the anti-collision effect. the

In the above-mentioned reinforcement structure of the front pillar of the automobile, the reinforcing plate is fixedly connected to the junction of the inner panel of the front pillar and the outer panel of the front pillar. In the technical solution, the edges of the reinforcing plate, the inner panel of the front pillar, and the outer panel of the front pillar are superimposed and fixed together, so that the structure is more compact and firm. the

In the aforementioned reinforcing structure of the front pillar of the automobile, the reinforcement plate is fixed to the inner panel of the front pillar and the outer panel of the front pillar by welding. the

In the aforementioned reinforcement structure for the front pillar of an automobile, the reinforcement plate is fixed to the inner panel of the front pillar and the outer panel of the front pillar through fasteners. the

In the aforementioned reinforcement structure for the front pillar of an automobile, the reinforcement plate is an integral structure made of steel plates. the

In the aforementioned reinforcement structure for the front pillar of an automobile, the reinforcement plate is provided with reinforcement ribs. In the technical solution, the anti-collision performance of the reinforcing plate can be enhanced by setting the reinforcing ribs. the

Compared with the existing technology, this technical solution optimizes the internal structure of the front pillar and sets the reinforcement plate to form a larger cavity between it and the inner plate of the front pillar. Due to the increase in the cross-sectional area that can bear the load, the updated structure Compared with the existing structure, it can bear a larger positive load, reduce the intrusion of the front pillar in the frontal collision, and better ensure the living space of the occupants. Moreover, the optimization method fully considers the requirements of technology and production. Its structure Simple and convenient process. the

Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments. the

Referring to the accompanying drawings, the reinforcing plate 3 used in this embodiment is a bar-shaped reinforcing member integrally stamped from a high-strength steel plate. In this embodiment, the reinforcing plate 3 is installed on the junction of the front pillar inner panel 1 and the front pillar outer panel 2, that is, the two ends of the reinforcing plate 3 are clamped between the front pillar inner panel 1 and the front pillar outer panel 2, and the welding Fix it so that a crash cavity 4 is formed between the reinforcing plate 3 and the inner panel 1 of the front pillar. The reinforcing plate 3 protrudes toward the front pillar outer panel 2, and its cross-sectional structure roughly matches the structure of the front pillar outer panel 2, which can maximize the space in the anti-collision cavity 4 to enhance the bearable load. In this embodiment, the maximum distance between the reinforcement plate 3 and the front pillar inner panel 1 can reach 46mm. the
