Abstract

The invention discloses a vehicle door buffer device, and belongs to the technical field of automobile manufacturing. The vehicle door buffer device comprises a threaded column which is arranged on the lower portion of an inner plate of a vehicle door and is in threaded connection with a buffer block, and a pressure-sensitive element which detects the gap between the vehicle door and a vehicle body when the vehicle door is closed is arranged on the buffer block; and a rotating shaft driven by a motor is fixed below the threaded column, and a wiring pin of the pressure-sensitive element penetrates through a core hole of the buffer block, a core hole of the threaded column and a core hole of the rotating shaft to be connected with the motor through a control module. The device can solve theproblems that the matching gap between an existing door assembly and a vehicle body difficultly guarantees avoidance of interference, paint damage and deformation between a vehicle door and the vehicle body during vehicle door closing or driving processes.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a car door buffer device. Background technique [0002] The door of the car is connected with the body through hinges. When the door is closed, the door will often pass through, and the door will interfere with the body, causing the body or door paint to drop or even deform. Therefore, in order to prevent this If the situation occurs, usually when assembling the door, a door buffer device will be installed on the left and right sides of the lower part of the door inner panel. The existing door buffer device includes a threaded column that is threaded on the door, and a buffer block is set on the threaded column. , by manually rotating the door buffer device to adjust the matching gap between the door and the body and its surrounding systems when the door is closed. However, in practical applications, it is difficult to adjust the buffer device in place when the ...
