Technical Field

The invention belongs to the field of automobile accessories, and particularly relates to an automobile door damping structure.

Background

The switching rate of car door is very high, and people all must open and shut the door on getting on or off the bus at every turn, and the shock attenuation of car door is all very important to the life of door and the comfort level that the switch was experienced. The existing automobile door has good shockproof effect on the contact part of the door and the automobile body, but neglects the damage of the shock to the door, namely the shock absorption of the interior of the door, and the door is internally provided with a plurality of parts.

Description

The invention discloses a shock absorption structure of an automobile door, aiming at solving the shock absorption problem of the automobile door, which can play a good shock absorption effect on the automobile door in the process of opening and closing the automobile door.

A shock absorption structure of an automobile door comprises an outer decoration plate, an inner metal plate and an inner decoration plate, wherein the inner metal plate is arranged between the outer decoration plate and the inner decoration plate, a shock absorption groove is formed in a circle of the edge of the back face of the inner decoration plate, a shock absorption bulge is formed in a circle of the edge of the front face of the inner metal plate, the shock absorption bulge on the inner metal plate corresponds to the shock absorption groove on the inner decoration plate, the shock absorption groove is used for bearing the shock absorption bulge, and the shock absorption bulge plays a role in buffering impact force; the back of the lower part of the interior trimming plate is provided with a groove, an inner energy absorption plate is arranged between the interior trimming plate and the inner metal plate, the inner energy absorption plate is arranged in the groove on the back of the interior trimming plate, and the inner energy absorption plate is arranged in the groove, so that the shock absorption effect between the interior trimming plate and the inner metal plate can be realized, and other parts cannot be influenced to be arranged between the interior trimming plate and the inner metal plate; the lower part back of interior panel beating is equipped with the recess, be equipped with outer energy-absorbing board between outer plaque and the interior panel beating, in the back recess of panel beating including outer energy-absorbing board sets up, outer energy-absorbing board sets up in the recess and both can play the shock attenuation between outer plaque and interior panel beating and can not influence the spare part installation between outer plaque and the interior panel beating again.

The shock absorption bulge is composed of three layers, wherein the upper layer and the lower layer are rubber pads, and the middle layer is shock absorption cotton.

The energy absorbing panel is PE foam as described above.

Has the advantages that: in the door closing process of the automobile, the collision between the automobile door and the automobile body can generate impact force, the interior trim panel firstly receives the impact force, the impact force is transmitted to the inner metal plate, the inner metal plate can be transmitted to the outer decorative plate, and the impact force can be well reduced by designing a related buffer structure among the outer decorative plate, the inner metal plate and the interior trim panel, so that the shock absorption effect is achieved.

In order to illustrate the invention more clearly, the invention is further illustrated by the following specific examples.
