Description

Technical Field

[0001] This application relates to the field of automotive parts testing technology, specifically to a cover plate durability fatigue testing fixture. Background Technology

[0002] The spare tire cover is installed inside the car's trunk, covering the spare tire and serving both decorative and covering purposes. The middle of the cover is usually connected by a hinge or flexible connector to allow it to be flipped. The cover needs to undergo a flipping durability test before leaving the factory.

[0003] Currently, the flipping test of tire cover plates is generally carried out manually, which is labor-intensive for workers; or a mobile flipping device is used for testing. For example, CN220472959U discloses a tire cover plate flipping durability testing device, which has a cantilever rotating on a rotating arm, and a traction rope connected to the cover plate on the cantilever. By rotating the rotating arm, the cantilever is driven to pull the cover plate to rotate through the traction rope. The flipping test is only carried out by driving the cover plate to flip on one side, which has low flipping test efficiency and long test time. Utility Model Content

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] See Figures 1 to 2 To further explain this application:

[0028] A fatigue testing fixture for a cover plate includes a support 1, a pressure plate assembly 3, a clamping plate assembly 2, and a flipping mechanism 5. The support 1 has a support rod 4, and the clamping plate assembly 2 is rotatably connected to the support rod 4. The clamping plate assembly 2 includes a first flip plate 21 and a second flip plate 22 supporting both sides of the cover plate 10. The first flip plate 21 and the second flip plate 22 are located on both sides of the support rod 4 and rotatably connected to it. The pressure plate assembly 3 is located at the top of the clamping plate assembly 2 and rotatably connected to the support 1. The pressure plate assembly 3 can press the cover plate 10 along the y-axis. The flipping mechanism 5 is located at the bottom of the clamping plate assembly 2 and is used to drive the first flip plate 21 and the second flip plate 22 to simultaneously flip the cover plate 10 upwards around the support rod 4, folding the cover plate 10. This improves testing efficiency and is applicable to testing cover plates 10 of different sizes, offering better versatility.

[0029] Compared to existing technologies that fix one side of the cover plate 10 and drive the other side of the cover plate 10 to rotate 180 degrees, this application drives both sides of the cover plate 10 to rotate simultaneously, so that the two sides of the cover plate 10 are close to each other. The two sides of the cover plate 10 only need to rotate 90 degrees to achieve the flipping and folding, which can improve the flipping speed of the cover plate 10, improve detection efficiency, and shorten detection time.

[0030] Combination Figure 1 The pressure plate assembly 3 includes a pressure plate and a locking component disposed on the pressure plate. One end of the pressure plate is rotatably connected to the bracket 1, and the locking component is located at the other end of the pressure plate. The locking component is used to connect the other end of the pressure plate to the bracket 1. The pressure plate is used to press the middle part of the cover plate 10, that is, the rotatable part of the cover plate 10, thereby fixing the cover plate 10. The locking component can achieve a detachable connection between the pressure plate and the bracket 1 by means of snaps, adhesives, etc. For example, Velcro can be used to connect the pressure plate to the bracket 1.

[0031] Combination Figure 1The flipping mechanism 5 includes a power component 51 and at least one set of connecting rod assemblies 52 respectively connected to the clamping plate assembly 2. The power component 51 may be a cylinder. The connecting rod assembly 52 is connected to the power component 51, and the power component 51 is used to drive the connecting rod assembly 52 to swing. The connecting rod assembly 52 includes a first lever 521 and a second lever 522, and a connecting rod 523 with a sliding groove. The connecting rod 523 is located between the first lever 521 and the second lever 522. The bracket 1 is provided with a hinge seat, and one end of both the first lever 521 and the second lever 522 is rotatably connected to the hinge seat. The power component 51 is connected to the connecting rod 523, and both the first lever 521 and the second lever 522 move along the sliding groove. Both the first lever 521 and the second lever 522 are provided with a rotating shaft, which slides within the sliding groove. The power component 51 drives the connecting rod 523 to move, forcing the first lever 521 and the second lever 522 to move along the sliding groove, thereby synchronously pushing the first flap 21 and the second flap 22 to flip and close synchronously. Figure 2 (The middle part flips upwards), which in turn causes the cover plate 10 to flip and fold, thus achieving a single fold.

[0032] In this embodiment, there are two sets of connecting rod assemblies 52, and the power component drives the connecting rods 523 to move synchronously through the connecting plate.

[0033] In one embodiment, the connecting rod assembly 52 is provided with a rolling component 6, which abuts against the clamping plate assembly 2. The rolling component 6 is disposed on the movable ends of the first lever 521 and the second lever 522, and is rotatably connected to the first lever 521 and the second lever 522; the rolling component 6 may be a roller; the rolling component 6 abuts against the first flap 21 and the second flap 22 to reduce frictional resistance and prevent jamming.

[0034] In one embodiment, a fixing component (not shown) is further included. This fixing component is disposed on the clamping plate assembly 2 and is used to fix the cover plate 10 to the clamping plate assembly 2. The fixing component includes several elastic clamps located on both sides of the first flap 21 and the second flap 22, ensuring that the cover plate 10 is always in contact with the first flap 21 and the second flap 22. When the first flap 21 and the second flap 22 are opened, they can simultaneously open both sides of the cover plate 10 to the sides.
