Technical Field

[0001] This utility model relates to the field of automotive interior rigidity testing technology, specifically to an auxiliary bracket for automotive interior rigidity testing. Background Technology

[0002] In the automotive manufacturing industry, interior door panels are crucial human-machine interface components, and their rigidity directly impacts passenger experience and safety. To ensure the reliability of interior door panels under conditions such as collisions and compression, rigidity testing is required using specialized testing support brackets.

[0003] However, existing auxiliary brackets for testing the rigidity of automotive interior panels lack flexibility in their adjustment mechanisms when dealing with interior door panels of different lengths and widths. They are unable to quickly adapt to the length and width of door panels of different sizes, and often require a lot of time for manual adjustment and calibration during the testing process, which seriously affects the testing efficiency. Therefore, an auxiliary bracket for testing the rigidity of automotive interior panels is proposed. Utility Model Content

[0004] This invention provides an auxiliary bracket for testing the rigidity of automotive interior components, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An auxiliary support for testing the rigidity of automotive interior trim includes a lifting support, which includes a movable base with a support column fixedly connected to the top of the movable base. The surface of the support column is provided with anti-slip texture. A left-right adjustment mechanism includes a crossbar with a sliding groove inside, and a slider slidably connected to the inner wall of the sliding groove. A testing mechanism includes a cylinder with a pressure sensor fixedly connected to the output end of the cylinder, and a pressure block fixedly connected to the bottom of the pressure sensor.

[0007] A further improvement of the present invention is that the lifting bracket further includes a lifting block, the interior of which is slidably connected to the surface of the supporting column.

[0008] A further improvement of this utility model is that: the lifting block is internally threaded with a first screw, one end of the first screw is rotatably connected to a locking block, and one side of the locking block engages with one side of the anti-slip texture.

[0009] A further improvement of this utility model is that: guide rods are fixedly connected to both ends of the card block near the first screw, and the surface of the guide rods is slidably connected to the interior of the lifting block.

[0010] A further improvement of the present invention is that the left and right adjustment mechanism further includes a fixing frame with a fixing screw threaded to its inner wall, one side of the fixing frame being rotatably connected to the surface of the slider, a second screw being threaded to the inside of the fixing frame, and a fixing pressure block being rotatably connected to the lower end of the second screw.

[0011] A further improvement of this utility model is that the testing mechanism further includes an electric telescopic rod, and a support rod is fixedly connected to the surface of the electric telescopic rod.

[0012] A further improvement of this utility model is that: an annular mounting seat is fixedly connected to the surface of the support rod, and a dial indicator is overlapped inside the annular mounting seat.

[0013] A further improvement of this utility model is that: the surface of the annular mounting base is threaded with a fixing screw, and one end of the fixing screw abuts against the surface of the dial indicator.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides an auxiliary bracket for testing the rigidity of automotive interior panels. The lifting bracket features anti-slip grooves on its support column, which, in conjunction with a first screw, engages with a locking block, and a guide rod structure, allows for flexible height adjustment.

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model provides an auxiliary support for testing the rigidity of automotive interior trim, including a lifting support, which includes a movable base 11, a support column 12 fixedly connected to the top of the movable base 11, and anti-slip texture 13 on the surface of the support column 12; a left-right adjustment mechanism, which includes a crossbar 21, a sliding groove 22 opened inside the crossbar 21, and a slider 23 slidably connected to the inner wall of the sliding groove 22; and a testing mechanism, which includes a cylinder 31, a pressure sensor 32 fixedly connected to the output end of the cylinder 31, and a pressure block 33 fixedly connected to the bottom of the pressure sensor 32.

[0024] In this embodiment, when the height of the support needs to be adjusted according to the size of the test piece, the first screw 15 is rotated counterclockwise, and the locking block 16 separates from the anti-slip texture 13 on the surface of the support column 12. The lifting block 14 can then slide freely along the support column 12 to the target height. Subsequently, the first screw 15 is rotated clockwise, and the locking block 16 moves towards the anti-slip texture 13 through threaded transmission until the toothed structure of the locking block 16 is fully engaged with the anti-slip texture 13. The position of the lifting block 14 is locked by the friction of the tooth surface, while the guide rod 17 restricts the rotation of the locking block 16, ensuring the stability and accuracy of the height adjustment.

[0025] Example 2

[0026] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the lifting bracket further includes a lifting block 14, the interior of the lifting block 14 is slidably connected to the surface of the supporting column 12, the interior of the lifting block 14 is threadedly connected to a first screw 15, one end of the first screw 15 is rotatably connected to a locking block 16, one side of the locking block 16 engages with one side of the anti-slip texture 13, the two ends of the locking block 16 near the first screw 15 are fixedly connected to guide rods 17, the surface of the guide rods 17 is slidably connected to the interior of the lifting block 14, the left and right adjustment mechanism further includes a fixing frame 24 with a fixing screw threadedly connected to the inner wall, one side of the fixing frame 24 is rotatably connected to the surface of the slider 23, the interior of the fixing frame 24 is threadedly connected to a second screw 25, the lower end of the second screw 25 is rotatably connected to a fixing pressure block 26.

[0027] In this embodiment, the slider 23 can slide freely in the sliding groove 22 of the crossbar 21, driving the fixed frame 24 and the test mechanism to move laterally until the pressure block 33 is aligned with the target test point of the interior door panel. After positioning, the fixing screw on the inner wall of the fixed frame 24 is rotated so that one end of it abuts against the surface of the crossbar 21 to limit the fixed frame 24. Then, the second screw 25 is rotated, and the fixing pressure block 26 at its lower end moves downward through the threaded transmission to fix the test piece inside the fixed frame 24. During the test, the cylinder 31 drives the pressure block 33 to apply a preset pressure to the surface of the interior door panel through the pressure sensor 32. The pressure sensor 32 collects pressure data in real time.

[0028] Example 3

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the testing mechanism further includes an electric telescopic rod 34, a support rod 35 is fixedly connected to the surface of the electric telescopic rod 34, an annular mounting seat 36 is fixedly connected to the surface of the support rod 35, a dial indicator 37 is overlapped inside the annular mounting seat 36, and a fixing screw 38 is threadedly connected to the surface of the annular mounting seat 36, with one end of the fixing screw 38 abutting against the surface of the dial indicator 37.

[0030] In this embodiment, the height of the support rod 35 can be finely adjusted by the electric telescopic rod 34, so that the probe of the dial indicator 37 in the annular mounting base 36 is pressed against the area to be measured on the door panel. By loosening or tightening the fixing screw 38, the installation angle and position of the dial indicator 37 can be adjusted to ensure that the probe is perpendicular to the door panel surface. When the pressure block 33 applies pressure and causes the door panel to deform, the dial indicator 37 simultaneously measures the amount of deformation. In conjunction with the pressure sensor 32, the force-deformation data is collected synchronously, providing multi-dimensional and accurate data for the rigidity performance analysis of the interior door panel. The pressure sensor 32 can be a PTJ-500A or CYG-1000B type, with a range of 0-1000N and an accuracy of ≤±0.5%FS, and outputs pressure electrical signals in real time. The dial indicator 37 adopts a DTS-10 digital display dial indicator or a MCH-50 mechanical dial indicator, with a range of 0-50mm and a resolution of ≤0.01mm, to ensure the accuracy of deformation measurement.

[0031] The working principle of this auxiliary bracket for testing the rigidity of automotive interiors will be explained in detail below.

[0032] like Figure 1-4 As shown, before the test, if the height of the bracket needs to be adjusted according to the size of the test piece, the first screw 15 is rotated counterclockwise, and the locking block 16 separates from the anti-slip texture 13 on the surface of the support column 12. The lifting block 14 can slide freely along the support column 12 to the target height. Then, the first screw 15 is rotated clockwise, and the locking block 16 moves towards the anti-slip texture 13 through the threaded transmission until the toothed structure of the locking block 16 is fully engaged with the anti-slip texture 13. The position of the lifting block 14 is locked by the friction of the tooth surface. At the same time, the guide rod 17 restricts the rotation of the locking block 16 to ensure the stability and accuracy of the height adjustment. When adjusting left and right, the slider 23 can slide freely in the sliding groove 22 of the crossbar 21, driving the fixed frame 24 and the test mechanism to move laterally until the pressure block 33 is aligned with the target test point of the interior door panel. After positioning, the fixing screw on the inner wall of the fixed frame 24 is rotated so that one end of it is engaged with the crossbar 21. 1. The surfaces abut against each other, limiting the fixed frame 24. Then, the second screw 25 is rotated, and the fixed pressure block 26 at its lower end moves downward through the threaded drive, fixing the test piece inside the fixed frame 24. During the test, the cylinder 31 drives the pressure block 33 to apply a preset pressure to the interior door panel surface through the pressure sensor 32. The pressure sensor 32 collects pressure data in real time. At the same time, the electric telescopic rod 34 can finely adjust the height of the support rod 35 so that the dial indicator 37 probe in the annular mounting seat 36 presses against the area to be tested on the door panel. By loosening or tightening the fixing screw 38, the installation angle and position of the dial indicator 37 can be adjusted to ensure that the probe is perpendicular to the door panel surface. When the pressure block 33 applies pressure and causes the door panel to deform, the dial indicator 37 simultaneously measures the amount of deformation. In conjunction with the pressure sensor 32, the synchronous acquisition of force-deformation data is achieved, providing multi-dimensional and accurate data for the rigidity performance analysis of the interior door panel.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
