Technical Field

[0001] This utility model relates to the field of automotive seat headrest operating force testing technology, and in particular to an auxiliary tool for rapid measurement of automotive seat headrest operating force. Background Technology

[0002] Car seat headrests are important safety components, and their comfort and operability directly affect the user experience. During the car manufacturing and seat production process, the operating force of the headrests (such as the force required to adjust the headrest height) needs to be tested to ensure that they meet relevant quality and safety standards.

[0003] Currently, the measurement of the operating force of headrests is mostly carried out using a general-purpose force gauge in conjunction with a temporary support frame, which has the following problems: the installation and positioning are cumbersome and inefficient; due to the diverse shapes of headrests, the general-purpose clamps have poor adaptability and are not stable, affecting the accuracy of the measurement.

[0004] Therefore, there is an urgent need for a measuring aid specifically designed for measuring the operating force of headrests, capable of quick clamping, precise positioning, and wide applicability. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rapid measuring tool for the operating force of an automotive seat headrest includes a headrest mounting module and an operating force measuring module. The headrest mounting module includes a headrest testing platform and a fixing part for fixing the headrest, which is mounted on the headrest testing platform. The fixing part is provided with a headrest rod connecting tube, and the headrest rod connecting tube is provided with a fixing screw for pressing and fixing the headrest rod to the headrest rod connecting tube. The operating force measuring module includes a base and a spring force gauge connected to the base. The base is provided with a slide rail, and a test tube for connecting the headrest rod is connected to the slide rail. An adjusting screw is connected to the test tube.

Figure 3This is an exploded view of an example of this utility model. This utility model provides a rapid measurement tool for the operating force of a car seat headrest, including a headrest mounting module 1, an operating force measurement module 2, and a headrest 3. The headrest mounting module 1 is used to fix the headrest 3 to be tested, and the operating force measurement module 2 is used to quickly measure the operating force of the headrest. The headrest mounting module 1 includes a headrest testing platform 11, a fixing part 12, a headrest rod connecting tube 13, and a fixing screw 14. The fixing part 12 is disposed on the headrest testing platform 11 for fixing the headrest 3, and a headrest rod is provided on the fixing part 12. The connecting tube 13, the spacing between the two headrest rod connecting tubes 13 can be fixed or adjustable depending on the headrest setting. Each headrest rod connecting tube 13 is equipped with a fixing screw 14, which is used to press and fix the headrest rod 31 to the connecting tube 13. The operating force measuring module 2 includes a base 21, a spring force gauge 22, a slide rail 23, a test tube 24, an adjusting screw 25, and a level (not shown). The spring force gauge 22 is connected to the base 21, and the slide rail 23 is mounted on the base 21. The number of slide rails 23 is preferably set to... Two parallel slide rails 23 are connected to test tubes 24 for connecting headrest rods 31. Different test tubes 24 have different lengths, diameters, or end contact head shapes to accommodate different headrest rod models and test point requirements. An adjusting screw 25 is connected to each test tube 24 to adjust the spacing between the test tubes 24. A level (not shown) is mounted on the base 21 to ensure the assistive device is in a horizontal working state. In a more specific embodiment, two test tubes 24 are provided, one of which... One test tube 24 is fixedly connected to the slide rail 23. The other test tube 24 can adjust the distance between the two test tubes 24 according to the adjustment of the adjusting screw 25. The adjusting screw 25 is threadedly connected to one of the fixed test tubes 24. The other movable test tube 24 is rotatably provided with a nut (not shown). The adjusting screw 25 is connected to the nut. When the adjusting screw 25 is rotated, the other movable test tube 24 can be driven to move along the slide rail 23, thereby adjusting the distance between the two test tubes 24 to match the headrest rod 31.

[0027] The following will refer to Figures 1 to 3 The working principle of this utility model will be explained.

[0028] The headrest 3 to be tested is installed onto the headrest test stand 11 using fixing screws 14. Specifically, the headrest rod 31 is tightened to the headrest rod connecting pipe 13 using fixing screws 14, ensuring the headrest 3 is securely installed and will not loosen or shift during testing. According to actual testing requirements, the base 21 is installed in a suitable position, ensuring its stability and providing smooth guidance for the movement of the test tube 24. The adjusting screw 25 is installed, and the position of the test tube 24 is adjusted according to the headrest specifications and testing requirements, preparing for subsequent measurements. Based on the approximate range of the headrest's operating force, a suitable test tube 24 is selected and installed on the slide rail 23. The spring balance 22 is correctly connected to the base 21, ensuring a secure connection that will not detach during measurement. At the corresponding test position, the test tube 24 can effectively contact the headrest rod 31 to apply force and measure the reaction force. During the application of the operating force, observe and read the value displayed on the spring balance. This value is the operating force of the headrest under the current operation. Record the data of each measurement, and take the average value of multiple measurements to improve the measurement accuracy.

[0029] When testing the operating force of a single headrest rod, only one test tube 24 needs to be installed on the slide rail 23 before testing. When testing the operating force of two headrest rods, one test tube 24 needs to be fixed on the slide rail 23 first, and then the other test tube 24 is adjusted by adjusting the lead screw 25 so that the distance between the two test tubes 24 matches the distance between the two headrest rods 31 to be tested.
