Description

Technical Field

[0001] This utility model relates to the field of automotive parts safety testing technology, specifically to an automotive membrane puncture resistance testing fixture. Background Technology

[0002] Automotive window film is a thin film installed on the surface of car windows. It is usually composed of multiple layers, including a polyester substrate, an adhesive layer, and a protective film. It has a variety of functions, such as heat insulation, sun protection, explosion protection, UV protection, and increased privacy. During driving, cars may encounter various unexpected situations, such as being hit by stones or impacted by external objects. Puncture resistance testing can assess the ability of automotive window film to resist punctures by sharp objects, ensuring that it can provide reliable safety protection for the occupants of the car and prevent injury from flying shards after the glass breaks.

[0003] Current puncture resistance testing fixtures are poor at simulating actual working conditions. During actual vehicle operation, the puncture force on the car film may come from different angles, while most existing fixtures can only perform simple vertical puncture tests, making it difficult to accurately simulate actual working conditions, resulting in a certain deviation between the test results and actual usage. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A puncture resistance testing fixture for automotive films, comprising:

[0006] The base has a fixed seat connected to the top center, and a pair of arc-shaped sleeves connected above the fixed seat. An arc-shaped plate is slidably connected inside the arc-shaped sleeves. A worktable is connected to the top of the arc-shaped plate. A pair of first L-shaped plates and a pair of second L-shaped plates are respectively connected above the worktable. A clamping mechanism is provided inside the first L-shaped plate and the second L-shaped plate.

[0007] The base is connected to upright plates on both sides of the workbench, and a puncture mechanism is slidably provided on the inner side of the upright plates.

[0008] In one possible implementation, the arc-shaped plate has a plurality of first positioning holes circumferentially arranged inside, and the arc-shaped sleeve has a plurality of second positioning holes circumferentially arranged inside. A screw rod is connected through the first and second positioning holes. One end of the screw rod is connected to a side plate, and the other end of the screw rod is threadedly connected to a nut.

[0009] In one possible implementation, the position of the first positioning hole corresponds to the position of the second positioning hole.

[0010] In one possible implementation, the clamping mechanism includes a U-shaped rod with clamping plates connected to both ends. A rubber pad is connected to the bottom of the clamping plates. A pair of return springs are correspondingly sleeved on the outer side of the U-shaped rod. One end of the return spring is fixedly connected to a first L-shaped plate, and the other end of the return spring is fixedly connected to the clamping plate.

[0011] In one possible implementation, a pair of through holes are provided on the top of the first L-shaped plate and the second L-shaped plate, and the pair of through holes are slidably connected to the U-shaped rod.

[0012] In one possible implementation, the puncture mechanism includes a movable plate with a puncture needle connected to the bottom center of the movable plate. Slider blocks are connected to both sides of the movable plate, and slide rails are slidably connected to the outer sides of the sliders. The back side of the slide rails is fixedly connected to the upright plate.

[0013] In one possible implementation, a bracket is connected to the front side of the upright plate, and a limiting plate is attached to the top of a pair of brackets, the limiting plate being located below the movable plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] By removing the screws from the inside of the front and rear curved plates and sleeves, the curved plates can be easily slid, making it convenient to rotate the worktable and automotive film at the top of the curved plates. Then, the screws are inserted back into the inside of the curved plates and sleeves to adjust and limit the angle of the worktable. This allows for flexible adjustment of the automotive film angle according to test requirements, simulating the puncture forces that the automotive film may experience from different angles in actual use, and more comprehensively testing the puncture resistance of the automotive film.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This application provides a puncture resistance testing fixture for automotive membranes, thereby addressing the problems in the prior art.

[0025] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0026] like Figures 1-4 As shown, a puncture resistance testing fixture for automotive films includes:

[0027] The base 8 has a fixed seat 11 connected to the top center of the base 8. A pair of arc-shaped sleeves 13 are connected above the fixed seat 11. An arc-shaped plate 10 is slidably connected inside the arc-shaped sleeves 13. A worktable 9 is connected to the top of the arc-shaped plate 10. A pair of first L-shaped plates 6 and a pair of second L-shaped plates 7 are connected above the worktable 9. A clamping mechanism is provided inside the first L-shaped plate 6 and the second L-shaped plate 7.

[0028] Above the base 8, on both sides of the workbench 9, there are upright plates 15, and a piercing mechanism is slidably installed on the inner side of the upright plates 15.

[0029] In some examples, the inside of the arc plate 10 is provided with several first positioning holes 16, and the inside of the arc sleeve 13 is provided with several second positioning holes 17. A screw 18 is connected through the inside of the first positioning holes 16 and the second positioning holes 17. One end of the screw 18 is connected to the side plate 12, and the other end of the screw 18 is threaded to the nut 19. After the screws 18 on both sides are removed from the inside of the arc plates 10 and the arc sleeve 13 on both sides, the arc plate 10 can be slid easily. Conversely, the screws 18 are inserted into the inside of the arc plates 10 and the arc sleeve 13 on both sides to complete the adjustment and limitation of the angle of the worktable 9.

[0030] In some examples, the position of the first positioning hole 16 corresponds to the position of the second positioning hole 17.

[0031] In some examples, the clamping mechanism includes a U-shaped rod 23, with clamping plates 21 connected to both ends of the U-shaped rod 23. A rubber pad 22 is connected to the bottom of the clamping plate 21. A pair of return springs 24 are correspondingly sleeved on the outer side of the U-shaped rod 23. One end of the return spring 24 is fixedly connected to the first L-shaped plate 6, and the other end of the return spring 24 is fixedly connected to the clamping plate 21. Pulling up the U-shaped rod 23 and the clamping plate 21 makes it easy to place the car film into the bottom of the clamping plate 21. Then, the return spring 24 is released, and the car film is fixed by utilizing the restoring effect of the return spring 24. By setting the rubber pad 22, it is beneficial to increase the friction between the car film and the clamping plate 21 and improve the stability effect.

[0032] In some examples, a pair of through holes 20 are provided on the top of the first L-shaped plate 6 and the second L-shaped plate 7, and the pair of through holes 20 are slidably connected to the U-shaped rod 23.

[0033] In some examples, the puncture mechanism includes a movable plate 3, with a puncture needle 14 connected to the bottom center of the movable plate 3. Slider 2 is connected to both sides of the movable plate 3, and slide rail 1 is slidably connected to the outer side of the slider 2. The back side of the slide rail 1 is fixedly connected to the upright plate 15. The limiting plate 4 is removed, and gravity drives the movable plate 3 and the puncture needle 14 to descend, thus completing the puncture of the car film.

[0034] In some examples, the front side of the upright plate 15 is connected to a bracket 5, and the top of the pair of brackets 5 is connected to a limiting plate 4. The limiting plate 4 is located below the movable plate 3. Before the experiment, the limiting plate 4 is placed on top of the pair of brackets 5 to support the movable plate 3 and prevent it from falling.

[0035] This invention allows for easy sliding of the arc-shaped plates 10 after the screws 18 on both sides are removed from the interior of the arc-shaped plates 10 and arc-shaped sleeves 13 on both sides. This facilitates the angle rotation of the worktable 9 on top of the arc-shaped plates 10 and the automotive film. Then, the screws 18 are inserted back into the interior of the arc-shaped plates 10 and arc-shaped sleeves 13 to adjust and limit the angle of the worktable 9. This allows for flexible adjustment of the angle of the automotive film according to test requirements, thereby simulating the puncture forces that the automotive film may experience from different angles in actual use, and more comprehensively testing the puncture resistance of the automotive film.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
