Abstract

The utility discloses a reinforcement structure of a car door which comprises an inner plate of the car door, a strengthen beam of a car door windowsill are arranged at the upper end of the inner plate of the car door, an anti- side- impact beam of the car door is arranged at the lower end of the inner plate of the car door, a third strengthen beam is arranged between the strengthen beam of the car door windowsill and the anti- side- impact beam of the car door, the third strengthen beam is fixed on the inner plate of the car door. The reinforcement structure of car door is improved in strength between the two beams by adding the third strengthen beam between a traditional anti- side- impact beam of the car door and a traditional strengthen beam of a car door windowsill. The combination of the three beams effectively improves the anti- side- impact performance of the car door, reduces inward damage in a side- impact course and achieves the aim of improving side- impact safety of a car. The reinforcement structure of the car door is simple in structure, good in manufacturability and low in cost.

Description

A car door reinforcement structure

technical field

The utility model relates to body parts, in particular to an automobile door reinforcement structure.

Background technique

The side impact performance of automobiles is related to the driving safety of automobiles, and is an important area of concern in the automobile industry. The reinforced structure of the car door directly affects the side impact performance of the car. The reinforced structure used in the traditional car door is composed of the door anti-side impact beam and the door sill reinforcement beam. The part between the reinforcement beams is relatively weak, and it is easy to cause a large amount of intrusion in this part during a side collision, resulting in excessive damage to the occupant in a side collision. Therefore, it is extremely necessary to increase the strength of the car door structure.

Utility model content

The purpose of the utility model is to provide a car door reinforcement structure for the above problems, which can effectively improve the side impact performance of the car door.

In order to achieve the above object, the solution adopted by the utility model is: a car door reinforcement structure, which includes a car door inner panel, a door window sill reinforcement beam is arranged at the upper end of the car door inner panel, and a door anti-side guard is provided at the lower end of the car door inner panel. The impact beam is provided with a third reinforcement beam between the door window sill reinforcement beam and the door anti-side impact beam, and the third reinforcement beam is fixed on the inner panel of the vehicle door.

The utility model improves the strength of the area between the two beams of the traditional car door by adding a third reinforcing beam between the traditional car door side-impact beam and the car door window sill reinforcing beam. The combination of the three beams effectively improves the side impact performance of the car door, reducing The amount of intrusion during the side collision of the car door is reduced, and the purpose of improving the safety of the side collision of the car is achieved; the utility model has the advantages of simple structure, good manufacturability and low cost.

Preferably, the third reinforcing beam is a long rod whose two ends respectively extend to the left and right edges of the inner panel of the door. The length of the third reinforcing beam transversely runs through the entire door inner panel, which is beneficial to improving the strength of the overall structure.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to understand the utility model more clearly, but they do not limit the utility model.

As shown in Figure 1, the utility model comprises a car door inner panel 4, and a door window sill reinforcement beam 1 is provided at the upper end of the car door inner panel 4, and a car door anti-side impact beam 2 is provided at the lower end of the car door inner panel 4, and a car door window sill reinforcement beam 2 is provided at the lower end of the car door inner panel 4. A third reinforcement beam 3 is provided on the door inner panel 4 between the beam 1 and the door anti-side impact beam 2, and the third reinforcement beam 3 is a long rod whose two ends respectively extend to the left and right ends of the door inner panel 4. The connection between the three reinforcing beams 3 and the inner panel 4 of the car door can be fixed connection methods such as welding, riveting, or bolts. Wherein, the shapes of the door and window sill reinforcement beam 1 , the door side-impact beam 2 , and the third reinforcement beam 3 can all adopt a round rod-shaped beam structure. The utility model provides a novel automobile door reinforcement structure, which can effectively reduce the intrusion amount of the side impact of the vehicle door and improve the performance of the side impact of the vehicle door.
