Problems solved by technology

[0004] The disadvantages of the above test are as follows: 1. The sliding door cannot be tested at the same time as the hinged door, which takes up a lot of space, and the front and rear doors cannot be tested at the same time; 2. The reliability of the cable push-pull is unstable and the noise is large

Embodiment 1

[0029] Such as figure 1 As shown, the test device for this kind of automobile sliding door includes a frame 1 and a linear guide rail 2 fixed on the frame 1 , and a support plate 3 is arranged on the linear guide rail 2 . The frame 1 is also fixed with a cylinder one 4 that can promote the support plate 3 to move along the linear guide rail 2, and the support plate 3 is fixed with an unlocking mechanism 5 that links to each other with the handle of the sliding door and can unlock the door lock of the sliding door.

[0030] Specifically, cylinder one 4 is a rodless cylinder, and the rodless cylinder includes a cylinder tube parallel to the linear guide rail 2 and a piston sliding in the cylinder tube, and the piston is fixedly connected with the support plate 3 . The unlocking mechanism 5 includes a cylinder 2 5a fixed on the support plate 3 and a nylon belt 5b, one end of the nylon belt 5b is sleeved with the handle of the sliding door, and the other end is connected with the ...

Embodiment 2

[0035] The difference between the second embodiment and the first embodiment is the unlocking mechanism 5. The unlocking mechanism 5 of the second embodiment includes a motor and a nylon belt 5b fixed on the support plate 3. The handle of the sliding door is connected with the sleeve, and the other end is fixedly connected with the running wheel. The rotation of the running wheel drives the nylon belt 5b to pull the handle of the sliding door outwards to unlock the door lock of the sliding door.

Embodiment 3

[0037]The difference between the third embodiment and the first embodiment is the unlocking mechanism 5. The unlocking mechanism 5 of the third embodiment includes a cylinder two 5a that is hinged on the support plate 3 and can rotate relative to the surface of the support plate 3. One end of the push rod of the cylinder two 5a is connected to the The door lock button of the car door is fixedly connected. When unlocking the door lock, cylinder 2 5a is perpendicular to the sliding door, and the push rod of cylinder 2 5a retreats to unlock the door lock; then cylinder 1 4 is activated, and the sliding door is pulled laterally by cylinder 2 5a, because cylinder 2 5a can move around The plate surface of the support plate 3 is free to rotate, so it can automatically adjust the angle with the sliding door, so as to adapt to different tracks of the sliding door.

Abstract

The invention provides a test device for an automobile sliding door, which belongs to the technical field of automobile testing. It solves the problem that the existing device can only test sliding doors, but cannot test hinged doors at the same time. The test device for the automobile sliding door includes a frame and a linear guide rail fixed on the frame. The linear guide rail is provided with a support plate, and the frame is also fixed with a cylinder that can push the support plate to move along the linear guide rail. The support plate An unlocking mechanism that is connected with the handle of the sliding door and can unlock the door lock of the sliding door is provided. Since the moving track of the sliding door is not affected by the moving track of the support plate, the test device for the sliding door of the automobile is suitable for various test conditions of straight or curved sliding doors.

Description

technical field [0001] The invention belongs to the technical field of automobile testing, and relates to a testing device for an automobile sliding door. Background technique [0002] In most existing vans, the front door adopts a hinged door for convenience, and the rear door adopts a sliding door structure. Therefore, the durability test for sliding doors is also essential. The sliding door durability test is mainly used to confirm the durability of the sliding door structure, functional components and related systems. The test method is mainly to repeatedly open and close the sliding door by simulating the door opening and closing method. [0003] At present, in the domestic automobile sliding door test, it is more common to use a steel wire rope to drag left and right through a double-acting cylinder with a rod to complete the test. For example, the invention of a sliding door durability test device published in a Chinese patent [Application No.: 201210357799.0] inclu...
