Description

Technical Field

[0001] The utility model relates to the technical field of automobile headrest detection devices, in particular to a flip headrest button unlocking force detection device. Background Art

[0002] Car seats are equipped with headrests, which can protect the necks of passengers and provide comfort. Headrests can usually be flipped to adjust their positions. Before flipping, you need to manually press a button to unlock it, and then the headrest flips automatically. In the production process of flippable headrests, the force required to unlock the button must be tested to determine whether the force is normal. Only normal ones can be shipped.

[0003] The existing method of testing the unlocking force of the flip headrest button is generally to use a manual handheld device for testing. On the one hand, the manual testing efficiency is low, and on the other hand, the flip headrest to be tested is not fixed, which easily leads to angle deviation, making the test results different each time even if the same product is tested, which greatly affects the accuracy of the test results. Therefore, it is necessary to provide a device to replace manual testing. Utility Model Content

[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] Example: Please refer to Figure 1 A flip headrest button unlocking force detection device includes a cylinder 2, a guide rail 32, a push-pull force gauge 3, a placement base 4 and a clamping structure. The cylinder 2, the guide rail 32, the placement base 4 and the clamping structure are arranged on a workbench 1. The push-pull force gauge 3 is slidably mounted on the guide rail 32, the guide rail 32 is located on one side of the placement base 4, and the piston rod 21 of the cylinder 2 is connected to the push-pull force gauge 3.

[0018] Specifically, the push-pull force gauge 3 is fixedly connected to the mounting plate 31, the mounting plate 31 is slidably connected to the guide rail 32 and is fixedly connected to the piston rod 21 of the cylinder 2, the push-pull force gauge 3 is slidably connected to the guide rail 32 through the mounting plate 31, and the push-pull force gauge 3 is fixedly connected to the piston rod 21 through the mounting plate 31. When the cylinder 2 causes the piston rod 21 to move telescopically, the mounting plate 31 and the push-pull force gauge 3 are driven to move along the guide rail 32.

[0019] The placement base 4 is provided with a matching groove 41, which matches with the lower surface of the flip headrest so that the flip headrest can be embedded in the placement base 4 during detection. The matching groove 41 includes a button groove 411 for placing the button end of the flip headrest. The button groove 411 is located at the edge of the placement base 4 and faces the push-pull force gauge 3. The push rod 301 of the push-pull force gauge 3 and the center of the button groove 411 are located at the same height. When the cylinder 2 causes the piston rod 21 to push the mounting plate 31 and the push-pull force gauge 3 to move along the guide rail 32 toward the placement base 4, the push rod 301 will contact the button on the flip headrest and apply force to unlock it. The magnitude of the unlocking force will be displayed on the push-pull force gauge 3.

[0020] The pressing structure is used to press the flip headrest onto the placement base 4 so that it will not be squeezed out of the placement base 4 under the force of the push rod 301. The pressing structure is a self-locking clamp 5, and the pressing head 51 of the self-locking clamp 5 is located above the matching groove 41. The pressing head 51 can be adjusted to press the center of the flip headrest. In this embodiment, the self-locking clamp 5 is a vertical self-locking clamp, which is convenient for vertical positioning and pressing.

[0021] Working principle of this embodiment: This embodiment provides a flip headrest button unlocking force detection device. During detection, first place the flip headrest on the matching groove 41 of the placement base 4, pull the pull rod of the vertical self-locking clamp to make the clamping head 51 press the flip headrest tightly against the placement base 4, start the cylinder 2, and push the mounting plate 31 and the push-pull force gauge 3 along the guide rail 32 toward the placement base 4 through the piston rod 21 of the cylinder 2. The push rod 301 of the push-pull force gauge 3 will contact the button on the flip headrest and apply force to unlock it. The magnitude of the unlocking force will be displayed on the push-pull force gauge 3, and then the piston rod 21 pulls the mounting plate 31 and the push-pull force gauge 3 back along the guide rail 32, records the data of the unlocking force required for the flip headrest button, and then pulls the pull rod of the vertical self-locking clamp to release the flip headrest, replaces the next flip headrest to be tested, and repeats the above operation. The flip headrest button unlocking force detection device requires manual intervention only when fixing and replacing the flip headrest, while the actual detection process is completely automatically implemented by the device. This avoids the result deviation caused by different detection actions of each person during manual detection, such as angles, etc. The flip headrests are fixed uniformly, and the push rod 301 is pushed in at the same angle and height, so the results are more accurate and the efficiency is improved compared to manual detection.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
