Description

Technical Field

[0001] This invention relates to the field of static pressure strength testing technology, specifically to a static pressure testing device and method for automotive door interior panels. Background Technology

[0002] Side-impact collisions are a frequent type of traffic accident with high fatality and injury rates. Because the side of a vehicle is relatively weak, occupants are close to the point of impact, and the buffer space is small, collisions can cause serious injuries. In a side-impact collision, the door trim panels are the components that directly contact the occupants; therefore, optimizing the structure of these panels can significantly improve occupant safety. Thus, researching the structural strength, stiffness, and energy absorption characteristics of door trim panels and making further optimizations to enhance vehicle side-impact safety is particularly important.

[0003] Chinese patent CN222579795U discloses a testing device for the static pressure of automotive door interior panels, belonging to the field of fixture technology. It includes a base plate, multiple support plates, lead screws, a clamping mechanism, a locking device, and a pressure testing device. The base plate has multiple lead screws. A first support plate is fixed on the lead screws and is parallel to the ground. A second support plate is positioned above the first support plate and is parallel to it. The second support plate slides on the lead screws. A clamping mechanism is provided on the second support plate, facing the first support plate. A locking device is fixed to the end of the lead screw and controls the movement of the second support plate on the lead screws. There are three or more lead screws. This invention can be adjusted according to different projects and setup requirements during the test. This patent is applicable to the measurement of static pressure on all automotive door interior panels, has a simple structure, is easy to operate, and has low manufacturing costs.

[0004] The aforementioned prior art announcements can be adjusted according to the actual situation during the test process based on different projects and different setting requirements. However, during the static pressure test of the door interior panel, when cracks appear, the cracks may not be obvious enough on the test surface. Therefore, it is necessary for staff to manually flip the door interior panel over for further inspection. This method increases the workload of staff and reduces the efficiency of the static pressure test of the door interior panel.

[0005] To address the above issues, a static pressure testing device and method for automotive door interior panels are proposed. Summary of the Invention

[0014] Furthermore, the protective assembly includes a curved rod fixedly installed on the intelligent finger robot and a rack plate B fixedly installed on the curved rod. A protective cover is provided at the bottom of the connecting block near one side, and straight rods A are fixedly installed on both the front and rear sides of the protective cover near the bottom. A toothed roller A is engaged at the top of the rack plate B, and a toothed roller B is engaged at the top of the toothed roller A.

[0015] Furthermore, a placement block is rotatably connected to the outer periphery of the straight rod A on the front side near the middle position, and the top of the placement block is fixedly connected to the connecting block. A straight rod B is rotatably connected to the rear side of the placement block, and the end of the straight rod B is fixedly connected to the toothed roller A.

[0016] A test method for a static pressure testing device for vehicle door interior panels includes the following steps: S1: Place the interior door panel on two support blocks B, and rotate the two rocker wheels to rotate the threaded tube fixed on the rocker wheels. Through the threaded rod A connected to the inner cavity of the threaded tube, the clamping plate can move downward under the limit of the two adjacent limit telescopic rods to clamp and limit the interior door panel.

[0017] S2: After fixing, the position of the connecting plate can be adjusted back and forth by setting electric slide rail B and electric slider B. With the cooperation of electric slide rail A and electric slider A, the position of electric telescopic rod can be limited, and the test position of stamping block can be adjusted.

[0018] S3: After adjustment, the door interior panel can be tested using the electric telescopic rod and stamping block, and the test status can be displayed on the PLC console by setting a camera.

[0019] S4: If a crack appears, the drive motor and intelligent finger robot can be started through the PLC control console. The drive motor's power output shaft rotates, causing the drive gear fixed at the end of the drive motor's power output shaft to rotate, which in turn allows the camera to rotate and the placement plate to move circumferentially. Under the action of the intelligent finger robot, the display marking spray bottle can be pressed to spray out white marking liquid to mark the cracked door interior panel.

[0020] S5: Moving the bent rod to one side allows the rack plate B fixed on the bent rod to move. The toothed roller A, which meshes with the rack plate B, can rotate the toothed roller B. The straight rod A, which is fixed on the toothed roller B, can rotate the protective cover 90 degrees to cover the camera. This prevents the display marking spray from spraying onto the camera and affecting the subsequent video recording effect.

[0021] S6: If there are no cracks on the test surface, the electric telescopic rod can be activated via the PLC control console to move the stamping block upward. During the upward movement, the rack plate A can be moved upward, which in turn causes the rotating gear meshed with the rack plate A to rotate. Through the cooperation of the transmission gear plate and the driven gear plate fixed on the rotating gear, the T-shaped rod can be rotated. Under the transmission of the synchronous pulley and the synchronous belt, the worm can be rotated. Through the worm wheel meshing with the worm, the adjacent crossbar can be rotated, which can then flip the door interior panel to 90 degrees. Afterward, the stamping block can be moved downward to test the door interior panel. The door interior panel is photographed by a camera. If this surface is damaged, the damaged door interior panel can be marked by the marking component.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By using a camera to record the static pressure of the car interior panel, when the connecting block moves upward, the worm gear can be rotated in conjunction with the flipping component, which in turn can rotate the meshing worm wheel, thereby flipping the car interior panel. This eliminates the need for manual material flipping, reducing the workload of workers. Continuing to record video through the camera can improve the accuracy of the static pressure test on the car door interior panel and enhance the effectiveness of the device.

[0023] 2. When damage occurs, the intelligent finger robot can work by using the PLC control console and marking components together. This allows the display marking spray limiter installed between the arc blocks to mark the damaged location of the door interior panel, preventing the damaged panel from being mixed with the intact panel and affecting the subsequent classification of the door interior panels.

[0024] 3. When the intelligent finger robot is working, with the cooperation of the protective components, the straight rod A can be rotated, which in turn allows the protective cover fixed on the straight rod A to rotate 90 degrees, covering the camera and preventing the display marking spray from spraying onto the camera and affecting the subsequent video recording effect.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] The purpose of this embodiment is to provide a static pressure testing device for car door interior panels, including a base 1 and a PLC control console 2 located on one side of the base 1 (the PLC control console 2 is electrically connected to all electrical components of the device). Support blocks A4 are fixedly installed on the top of the base 1 near both sides. A connecting frame 3 is fixedly installed on the rear side of the base 1. A flipping component 7 is provided on the rear side of the connecting frame 3. An electric telescopic rod 5 is fixedly installed on the top of the inner cavity of the connecting frame 3. A connecting block 6 is fixedly installed at the bottom end of the electric telescopic rod 5. A connecting plate 40 is provided at the bottom of the connecting block 6. A connecting block 10 is provided on one side of the inner cavity of the connecting plate 40. A camera 20 is fixedly installed at the bottom of the connecting block 10 (the camera 20 can display the captured image on the PLC control console 2 in real time, making it convenient to observe the testing status of the car door interior panels). A stamping block 30 is fixedly installed at the middle position of the bottom of the connecting plate 40. A marking component 8 is provided on the bottom of the connecting plate 40 near the other side. A protective component 9 is provided on one side of the inner cavity of the connecting plate 40. To clearly observe the condition of the door interior panels after the test, in this embodiment, as shown in 2 and Figure 8 As shown, the flipping assembly 7 includes a connecting rod 71 fixedly installed on the rear side of the connecting block 6 and a rack plate A72 fixedly installed on the bottom end of the connecting rod 71 (the end of the connecting rod 71 passes through the rear side of the inner cavity of the connecting frame 3). A rotating gear 73 is engaged on the other side of the rack plate A72. A transmission gear 74 is fixedly installed on the rear side of the rotating gear 73. A driven gear 75 is engaged on the rear side of the transmission gear 74. A T-shaped rod 77 is provided on the rear side of the driven gear 75. An L-shaped plate 76 is rotatably connected to the outer periphery of the T-shaped rod 77 near the rear end. The front side of the L-shaped plate 76 is fixedly connected to the connecting frame 3. A worm gear 78 is provided on one side of the T-shaped rod 77. A worm wheel 79 is engaged at the bottom of the worm gear 78.

[0030] Specifically, with the cooperation of the flipping component 7, the worm 78 can be rotated, which in turn can rotate the meshing worm wheel 79, enabling the automotive interior panel to be flipped over without manual turning, reducing the workload of workers. Furthermore, the camera 20 continues to record video, which can improve the accuracy of the static pressure test of the door interior panel and improve the effectiveness of the device.

[0031] A reset telescopic rod 751 is fixedly installed at the rear center of the driven gear 75, and the rear end of the reset telescopic rod 751 is fixedly connected to the T-shaped rod 77. A reset spring 752 is movably sleeved on the outer periphery of the reset telescopic rod 751, and the two ends of the reset spring 752 are fixedly connected to the driven gear 75 and the T-shaped rod 77 respectively. A rotating shaft 731 is fixedly installed at the front center of the rotating gear 73, and the front end of the rotating shaft 731 is rotatably connected to the connecting frame 3. A support plate 732 is rotatably connected to the outer periphery of the rotating shaft 731, and the bottom of the support plate 732 is fixedly connected to the L-shaped plate 76.

[0032] Specifically, by using the reset telescopic rod 751 and the reset spring 752 in conjunction, when the rack plate A72 moves downward and the transmission gear plate A74 rotates, the driven gear plate 75 cannot rotate. However, when the rack plate A72 moves upward and the transmission gear plate A74 rotates, the driven gear plate 75 can rotate, providing power for flipping the interior door panel. The support plate 732 can support the rotating shaft 731.

[0033] A support block C781 is rotatably connected to the outer periphery of the worm 78 near the middle position, and one side of the support block C781 is fixedly connected to the connecting frame 3. Synchronous pulleys 782 are fixedly sleeved on the outer periphery of the worm 78 and the T-shaped rod 77 near the rear end, and a synchronous belt 783 is sleeved on the synchronous pulleys 782 together.

[0034] Specifically, the worm 78 can be supported by the support block C781, and the worm and T-shaped rod 77 can be rotated synchronously by the synchronous pulley 782 and the synchronous belt 783.

[0035] Two support blocks A4 each have a crossbar 41 that moves through them near the top on one side of their opposite sides. A fixed plate 42 is fixedly installed at one end of each crossbar 41. A support block B43 is fixedly installed near the middle on one side of each fixed plate 42. A fixed block 44 is fixedly installed near the top on one side of each support block A4. A threaded tube 45 moves through the top of each fixed block 44. A rocker wheel 47 is fixedly installed at the top of each threaded tube 45. A threaded rod A46 is threadedly connected to the inner cavity of each threaded tube 45. A clamping plate is fixedly installed at the bottom of each threaded rod A46. A limit telescopic rod 48 is fixedly installed near both sides of the top of each clamping plate. The top of each limit telescopic rod 48 is fixedly connected to the fixed block 44.

[0036] Specifically, the interior door panel is placed on two support blocks B43, and rotating the two rocker wheels 47 causes the threaded tube 45 fixed on the rocker wheels 47 to rotate. Through the threaded rod A46 threadedly connected to the inner cavity of the threaded tube 45, the clamping plate can move downward under the limit of the two adjacent limiting telescopic rods 48, thereby clamping, limiting and fixing the interior door panel.

[0037] An electric slide rail A31 is fixedly installed on the top of the inner cavity of the connecting frame 3. An electric slider A32 is slidably connected to the outer periphery of the electric slide rail A31. A disc 33 is fixedly installed on the bottom of the electric slider A32, and the bottom of the disc 33 is fixedly connected to the electric telescopic rod 5. An electric slide rail B61 is fixedly installed near the middle position of the bottom of the connecting block 6. An electric slider B62 is slidably connected to the outer periphery of the electric slide rail B61, and the bottom of the electric slider B62 is fixedly connected to the connecting plate 40.

[0038] Specifically, by setting electric slide rail B61 and electric slider B62, the position of connecting plate 40 can be adjusted back and forth. With the cooperation of electric slide rail A31 and electric slider A32, the position of electric telescopic rod 5 can be limited, the test position of stamping block 30 can be adjusted, and different positions of door interior panel can be tested, thus improving the test effect of door interior panel.

[0039] To avoid mixing damaged and intact door trim panels and affecting subsequent classification of door trim panels, in this embodiment, as follows: Figure 3 , Figure 6 and Figure 9 As shown, the marking assembly 8 includes a placement plate 81 located on the other side of the connecting plate 40 and a U-shaped seat 82 fixedly installed at the bottom of the placement plate 81. A knob 84 is provided on the front side of the U-shaped seat 82, and a threaded rod B83 is fixedly installed on the rear side of the knob 84. (The outer periphery of the threaded rod B83 has opposite external threads near the front and rear ends.) The rear end of the threaded rod B83 moves through the inner cavity sidewall of the U-shaped seat 82 and is rotatably connected to the U-shaped seat 82. Threaded sleeves 85 are threadedly connected to the outer periphery of the threaded rod B83 near the front and rear ends. Vertical rods 86 are fixedly installed at the bottom of each threaded sleeve 85. Arc-shaped blocks 87 are fixedly installed at the bottom of each vertical rod 86. A smart finger robot 88 is fixedly installed near one side of the bottom of the placement plate 81. (The smart finger robot 88 is existing technology, and its working principle will not be described in detail. When the smart finger robot 88 is working, the nozzle on the display marking spray bottle can be pressed to spray out the white marking liquid in the display marking spray bottle, which can mark the interior trim panels of the car door.)

[0040] Specifically, rotating the knob 84 causes the threaded rod B83 to rotate, and the threaded sleeve 85, which is threadedly connected to the threaded rod B83, moves to the opposite side. The vertical rod 86, which is fixed to the threaded sleeve 85, causes the two arc-shaped blocks 87 to move to the opposite side, thereby fixing the real-marking spray bottle.

[0041] Limiting blocks 851 are fixedly installed at the bottom of each threaded sleeve 85, and limiting rods 852 are provided through each other on opposite sides of the limiting blocks 851. The two ends of the limiting rods 852 are fixedly connected to the inner cavity sidewall of the U-shaped seat 82. A gear seat 811 is fixedly installed on one side of the placement plate 81, and the top of the gear seat 811 is rotatably connected to the connecting plate 40. One side of the connecting block 10 is fixedly connected to the gear seat 811. An installation block 814 is fixedly installed on one side of the connecting plate 40. A drive motor 813 is fixedly installed at the bottom of the installation block 814, and a drive gear 812 is fixedly installed at the end of the power output shaft of the drive motor 813. The drive gear 812 is meshed with the gear seat 811.

[0042] Specifically, by setting the limit block 851 and the limit rod 852, the threaded sleeve 85 can be limited when it moves. When the power output shaft of the drive motor 813 rotates, the drive gear 812 fixed at the end of the power output shaft of the drive motor 813 can rotate, which in turn can rotate the gear seat 811 that meshes with it, and the placement plate 81 can move circumferentially, thereby improving the visibility of the spray coating.

[0043] To avoid spraying the indicator spray onto camera 20 and affecting subsequent video recording, in this embodiment, as shown in 3 and... Figure 7 The protective component 9 includes a curved rod 91 fixedly installed on the intelligent finger robot 88 and a rack plate B92 fixedly installed on the curved rod 91. A protective cover 96 is provided at the bottom of the connecting block 10 near one side, and straight rods A95 are fixedly installed on the front and rear sides of the protective cover 96 near the bottom. A toothed roller A93 is engaged at the top of the rack plate B92, and a toothed roller B94 is engaged at the top of the toothed roller A93. The front side of the toothed roller B94 is fixedly connected to the adjacent straight rod A95.

[0044] Specifically, when the intelligent finger robot 88 is working, with the cooperation of the protective component 9, the straight rod A95 can be rotated, which in turn allows the protective cover 96 fixed on the straight rod A95 to rotate to 90 degrees, covering the camera 20 and preventing the display marking spray from being sprayed onto the camera 20, thus affecting the subsequent video recording effect.

[0045] A placement block 951 is rotatably connected to the outer periphery of the front straight rod A95 near the middle position, and the top of the placement block 951 is fixedly connected to the connecting block 10. A straight rod B952 is rotatably connected to the rear side of the placement block 951, and the end of the straight rod B952 is fixedly connected to the toothed roller A93.

[0046] Specifically, the straight rod A95 can be supported by setting the placement block 951, and the toothed roller A93 can be supported by setting the straight rod B952.

[0047] A test method for a static pressure testing device for vehicle door interior panels includes the following steps: S1: Place the interior door panel on the two support blocks B43 and rotate the two rocker wheels 47 to rotate the threaded tube 45 fixed on the rocker wheels 47. Through the threaded rod A46 threadedly connected to the inner cavity of the threaded tube 45, the clamping plate can move downward under the limit of the two adjacent limit telescopic rods 48 to clamp and limit the interior door panel.

[0048] S2: After fixing, the position of the connecting plate 40 can be adjusted back and forth by setting the electric slide rail B61 and the electric slider B62. With the cooperation of the electric slide rail A31 and the electric slider A32, the position of the electric telescopic rod 5 can be limited, and the test position of the stamping block 30 can be adjusted.

[0049] S3: After adjustment, the door interior panel can be tested by the electric telescopic rod 5 and the stamping block 30, and the test status can be displayed on the PLC console 2 by setting the camera 20.

[0050] S4: If a crack appears, the drive motor 813 and the intelligent finger robot 88 can be started through the PLC control console 2. The rotation of the power output shaft of the drive motor 813 drives the drive gear 812 fixed at the end of the power output shaft of the drive motor 813 to rotate, which in turn enables the camera 20 to rotate and the placement plate 81 to move circumferentially. Under the action of the intelligent finger robot 88, the display marking spray bottle can be pressed to spray out white marking liquid to mark the cracked door interior panel.

[0051] S5: Moving the bent rod 91 to one side allows the rack plate B92 fixed on the bent rod 91 to move. The toothed roller A93, which meshes with the rack plate B92, allows the toothed roller B94 to rotate. The straight rod A95, which is fixed on the toothed roller B94, allows the protective cover 96 to rotate 90 degrees, covering the camera 20 to prevent the display marking spray from spraying onto the camera 20 and affecting the subsequent video recording effect.

[0052] S6: If there are no cracks on the test surface, the electric telescopic rod 5 can be activated via PLC control console 2 to move the stamping block 30 upward. During the upward movement, the rack plate A72 can be moved upward, which in turn causes the rotating gear 73 meshing with the rack plate A72 to rotate. Through the cooperation of the transmission gear plate 74 and the driven gear plate 75 fixed on the rotating gear 73, the T-shaped rod 77 can be rotated. Under the transmission of the synchronous pulley 782 and the synchronous belt 783, the worm 78 can be rotated. Through the worm wheel 79 meshing with the worm 78, the adjacent crossbar 41 can be rotated, which can flip the door interior panel to 90 degrees. Afterward, the stamping block 30 can be moved downward to test the door interior panel. The camera 20 can capture images of the door interior panel. If this surface is damaged, the damaged door interior panel can be marked by the marking component 8.

[0053] In summary, the working principle of this invention is as follows: During the static pressure test of the door interior panel, the door interior panel can be placed on two support blocks B43. Then, rotating the two rocker wheels 47 causes the threaded tube 45 fixed on the rocker wheels 47 to rotate. The threaded rod A46, threadedly connected to the inner cavity of the threaded tube 45, allows the clamping plate to move downwards under the limitation of two adjacent limiting telescopic rods 48, thus clamping and fixing the door interior panel. Afterwards, the position of the electric telescopic rod 5 can be adjusted by the cooperation of the electric slide rail A31 and the electric slider A32. Furthermore, by setting the electric slide rail B61 and the electric slider B62, the position of the connecting plate 40 can be adjusted. The front and rear positions can be adjusted. By setting the stamping block 30, the door interior panel can be tested. After the test is completed, the staff can watch the test status of the camera 20 through the PLC control console 2. If a crack is found, the drive motor 813 and the intelligent finger robot 88 can be started through the PLC control console 2. The drive motor 813's power output shaft rotates, driving the drive gear 812 fixed at the end of the drive motor 813's power output shaft to rotate, thereby enabling the camera 20 to rotate. This allows the placement plate 81 to move circumferentially. Under the action of the intelligent finger robot 88, the display marking spray bottle can be pressed to spray white marking liquid, marking the cracked door interior panel. When the intelligent finger robot 88 is working, the curved rod 91 fixed to the intelligent finger robot 88 can be moved to one side, which in turn can move the rack plate B92 fixed to the curved rod 91. The toothed roller A93, which meshes with the rack plate B92, can rotate the toothed roller B94. The straight rod A95 fixed to the toothed roller B94 can rotate the protective cover 96 90 degrees, covering the camera 20 to prevent the display marking spray from spraying onto the camera 20 and affecting the subsequent camera recording effect. If there are no cracks on the test surface, the electric telescopic rod 5 can be activated through the PLC control console 2 to move the stamping block 30 upward. During the upward movement, the rack can move. Plate A72 moves upward, which in turn causes the rotating gear 73 meshing with the rack plate A72 to rotate. Through the cooperation of the transmission gear 74 and the driven gear 75 fixed on the rotating gear 73, the T-shaped rod 77 can rotate. Under the transmission of the synchronous pulley 782 and the synchronous belt 783, the worm 78 can rotate. Through the worm wheel 79 meshing with the worm 78, the adjacent crossbar 41 can rotate, thereby flipping the door interior panel to 90 degrees. Then, the stamping block 30 can move downward to test the door interior panel. The camera 20 takes a picture of the door interior panel. If this surface is damaged, the damaged door interior panel can be marked by the marking component 8.
