Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

The anti-collision automobile door inner and outer trim panel shown in fig. 1 comprises an inner trim panel 100 and an outer trim panel 200, wherein the inner trim panel 100 is arranged at the inner side of the outer trim panel 200, damping cotton 110 is fixed between the inner trim panel 100 and the outer trim panel 200 through glue, the outer trim panel 200 comprises an outer surface plate 220 and an inner support plate 210, the inner support plate 210 is fixed at the inner side of the outer surface plate 220 through screws, and compression springs 201 are uniformly distributed between the inner support plate 210 and the outer surface plate 220.

As shown in fig. 1-2, the cushion cotton 110 is disposed between the interior trim panel 100 and the exterior trim panel 200 at a position where no other mechanism 300 is disposed, the other mechanism 300 refers to a mechanism such as an automobile window lifting mechanism disposed between the interior trim panel 100 and the exterior trim panel 200 to avoid disturbing the operation of the other mechanism 300, the specific cushion cotton 110 is fixed inside the exterior trim panel 200 by glue, a protrusion 111 is integrally formed on the cushion cotton 110, and the specific protrusion 111 is in the shape of two cones with opposite conical tops, so that the cushion effect is achieved by adopting the shape, and a good sound insulation effect is also achieved when no collision occurs.

As shown in fig. 3, an outward flange 211 is integrally formed around the inner support plate 210 for being fixed to the outer plate 220, and a recess 212 is integrally formed on the inner support plate 210, so that a gap is formed between the inner support plate 210 and the outer plate 220 for installing the compression spring 201.

As shown in fig. 4, the inner side of the outer surface plate 220 is welded and fixed with uniformly distributed circular ring pieces 221, each circular ring piece 221 corresponds to one compression spring 201, and one end of each compression spring 201 is clamped in each circular ring piece 221; the other end of the compression spring 201 is uniformly distributed in the recess 212, the uniformly distributed cylinders 213 are integrally formed in the specific recess 212, one compression spring 201 is sleeved on each cylinder 213, the compression spring 201 is clamped and fixed on the cylinder 213, the compression spring 201 is fixed between the outer surface plate 220 and the inner support plate 210 through the structure, and meanwhile, the ring piece 221 and the cylinders 213 can also increase the strength of the vehicle door when being impacted.

As shown in fig. 4, the compression spring 201 is a conical spring, and the small end of the compression spring 201 is fixed on the inner support plate 210, so that the compression spring 201 can better transmit the impact force transmitted from the outer skin 220 to the inner support plate 210.
