Door guard plate anti-collision buckle, door guard plate mounting structure and door guard plate dismounting method

Abstract

The invention discloses a door guard plate anti-collision buckle, a door guard plate mounting structure and a door guard plate dismounting method. The door guard plate anti-collision buckle comprises a clamping head and a clamping base, the clamping head comprises a buckle head, a buckle arm, a limiting plate and a chuck, an insertion hole is formed in the middle of the clamping base, a through channel is formed in the top end of the clamping base in the direction perpendicular to the insertion hole, a pluggable clamp is arranged in the channel, the pluggable clamp comprises a bayonet part capable of being elastically opened and closed, the buckle head can be inserted into the inserting hole and matched with the bayonet part for reverse clamping and limiting, due to the fact that the buckle head still has large displacement in the direction of going deep into the inserting hole, when collision occurs, an interior trimming panel assembly has larger buffering deformation, and a human body is protected; and according to the door protection plate mounting structure with the anti-collision buckles, the anti-collision buckles are additionally arranged at the positions, corresponding to important parts such as shoulders and pelvis of passengers, of the door plate for buffering, and harm to human bodies is reduced. The disassembling method aims at the structure of the anti-collision buckle, and the door protection plate is easy to disassemble.

Description

technical field [0001] The invention relates to the field of vehicle door assembly, in particular to an anti-collision buckle of a door guard plate, a door guard plate installation structure and a dismounting method. Background technique [0002] In the regulations of the new version of C-NCAP, the weight of the side impact barrier is increased, so there is a higher requirement for the anti-collision performance of the front and rear door structures. At present, most of the car doors adopt the structure of injection molding. Different modeling parts are superimposed and combined into an ideal three-dimensional door interior panel with the principle of building blocks. The decorative guard plate assembly is inserted and buckled on the door sheet metal, and then fixed with screws. When riding, the elbows of the human body are generally placed on the control panel or the armrest decorative panel connected to the middle trim, the small arms fit on the middle trim, the shoulders...

AI Technical Summary

Problems solved by technology

When riding, the elbows of the human body are generally placed on the control panel or the armrest decorative panel connected to the middle trim, the small arms fit on the middle trim, the shoulders and chest correspond to the end position of the upper body, the pelvis and the abdomen Corresponds to the end position of the lower body, so that when a side collision occurs, these parts of the human body will directly squeeze and collide with the corresponding parts of the interior trim assembly, and the impact damage will be the largest. The existing interior trim assembly Although it is designed with a skin or cushion structure for cushioning, when facing a larger side impact, the strength of its own body structure is relatively high, and it cannot provide sufficient deformation cushioning protection for passengers.

[0003] In addition, the working principle of some ordinary buckles such as plastic buckles is that the buckle head installed on the interior guard panel assembly is deformed and squeezed into the In the mounting hole of the door sheet metal, the clip is restored and locked. Due to installation reasons, the interference size of the clip should not be too large, resulting in poor tensile performance of the clip, and loosening and loud noise may occur after long-term work. question
