Description

Technical Field

[0001] The utility model relates to the technical field of four-door and two-cover detection, and specifically relates to a switch detection device for four-door and two-cover of an automobile. Background Art

[0002] The four doors and two covers of a car are important components of the car body, and the reliability of their opening and closing directly affects the safety and comfort of the car. The four doors include the switch of the driver's door and the door in the passenger compartment, and the two covers include the engine hood and the trunk lid. The opening and closing of the four doors and two covers of a car involves the sealing and anti-theft performance of the car. The door link is very important in the detection of the four doors and two covers, so the sensitivity and reliability of the door closing are very important.

[0003] If the door switch is not closed firmly, the sealing performance of the door will be reduced, thus affecting the overall sealing performance of the car and increasing the occurrence of problems such as wind noise and dust entering the car. If the engine hood cannot be closed properly, it will affect the heat dissipation and sealing of the engine and increase safety hazards. A switch that is not closed firmly will reduce the overall quality and image of the car and may affect consumers' impression of the car.

[0004] At the same time, the switch also needs to be reliable, sensitive and stable to ensure that there will be no misoperation or inoperability in the case of frequent use. The last step before the car leaves the factory is to conduct random inspections on the car and test the switch. Therefore, we propose a switch detection device for four doors and two covers of a car to detect problems with the switch in time, thereby ensuring the safety and comfort of the car.

[0022] There are two support rods 6, which are arranged vertically symmetrically.

[0023] Working principle: When testing the switch of four doors and two covers, for the detection process of the door switch closure, first determine the position of the circular hole bottom plate 1, and at the same time, circular holes are evenly opened on the surface of the circular hole bottom plate 1, which can be fixed by bolts and other parts, and then set the angle of the base structure 2. The base structure 2 is fixed to the circular hole bottom plate 1 by a screw hole plate 21, and a convex block 22 is set on the top. The convex block 22 is cylindrical, and there is a gap between the sleeve block 23 and the screw hole plate 21. The sleeve block 23 can be sleeved on the outer wall of the convex block 22 and rotated. After setting the orientation of the support plate 3 on the top of the sleeve block 23, the screw 24 penetrates the sleeve block 23 and the screw hole plate 21 contact, and the threaded connection is achieved by rotation, so as to limit the base structure 2.

The universal joint rod 52 is a combination of circular support rods arranged at both ends of the universal joint, so that the center has an angle adjustment, and when reciprocating When the cylinder 4 is pulled back and forth, the angle is adjusted through the universal joint rod 52 to avoid jamming during operation. The reciprocating cylinder 4 provides reciprocating power to realize the reciprocating switch closing test of the car door; at the same time, the round hole bottom plate 1 can be fixed to the wall, and the pulling structure 5 can be replaced by a suction cup structure to realize the test of the hatch and the trunk door. When the car door is opened, the car door will fit with the rubber block 8, and the rubber block 8 will be used for shielding and buffering. The rubber block 8 is glued to the outside of the baffle 7, and the other side of the baffle 7 is connected and fixed to the support plate 3 through the support rod 6 to test whether the door switch can be reset normally and the durability of the switch.
