[0022] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1 to 6 As shown, a force detection device for automobile interior door panel comprises a workbench 1, a detection mechanism 11, a mounting plate 2 and a fixing plate 3; the workbench 1 is arranged on the ground through a plurality of supporting legs; the detection mechanism 11 is arranged on the workbench 1; the mounting plate 2 is movably arranged on the workbench 1; the fixing plate 3 is movably arranged on the mounting plate 2; a movable flipping movement mechanism 4 is also arranged on the fixing plate 3, and a fixing part 5 for the automobile interior door panel is arranged on the flipping movement mechanism 4.

[0024] When it is necessary to perform force detection on the automobile interior door panel, first drive the flip moving mechanism 4 to adjust the position of the fixing part 5 to suit the automobile interior door panel that needs to be detected at present, then place the automobile interior door panel on the flip moving mechanism 4 on the fixing plate 3, and then fix the automobile interior door panel on the positioning mechanism through the fixing part 5, and then drive the automobile interior door panel to be lifted and turned ninety degrees through the flip moving mechanism 4, and then push the mounting plate 2 to move on the workbench 1, or drive the mounting plate 2 to move on the workbench 1 through an external driving source, so that the automobile interior door panel is close to the detection mechanism 11, and then perform force detection on the automobile interior door panel through the detection mechanism 11, and the flip moving mechanism 4 can drive the fixing part 5 to move, so that the automobile interior door panels of different specifications can be fixed, which can improve the practicality of the entire device, and through the flip moving mechanism 4, the automobile interior door panel can be installed on the flip moving mechanism 4 more conveniently and labor-saving.

[0025] Reference Figure 2 As shown, the flipping and moving mechanism 4 includes a positioning block 41 and a slider 43; at least two positioning blocks 41 are symmetrically arranged on the fixed plate 3, and the positioning block 41 is slidably connected to the fixed plate 3, and the fixed plate 3 is provided with a positioning groove 42 for the positioning block 41 to move; the number of the sliders 43 is the same as the number of the positioning blocks 41 and is arranged on the positioning block 41 in a one-to-one correspondence, and the slider 43 is slidably connected to the fixed plate 3, and the fixed plate 3 is provided with a slide groove 44 for the slider 43 to move.

[0026] The two positioning blocks 41 are synchronously moved toward each other in the positioning grooves 42 of the fixing plate 3, thereby driving the fixing parts 5 on the positioning blocks 41 to also synchronously move toward each other, so that the automobile interior door panels of different specifications can be fixed, and the slider 43 is moved in the slide groove 44 of the fixing plate 3 to limit the positioning block 41, thereby preventing the positioning block 41 from falling off the fixing plate 3, and then after the automobile interior panel is installed on the positioning block 41, the fixing plate 3 is driven to rise and flipped ninety degrees, so that the automobile interior door panel is perpendicular to the fixing plate 3, and then the force detection of the automobile interior door panel is performed.

[0027] Reference Figure 3As shown, a moving component 45 is provided on the fixed plate 3, and the moving component 45 includes a first rotating motor 452, a connecting shaft 453, a first rotating screw 451 and a second bevel gear 455; the first rotating motor 452 is arranged at the bottom of the fixed plate 3; the connecting shaft 453 is arranged on the output end of the first rotating motor 452, and the first bevel gear 454 is arranged on the connecting shaft 453; the first rotating screw 451 is arranged at the bottom of the fixed plate 3 through a bearing seat, and the first rotating screw 451 is threadedly connected to the positioning block 41; the second bevel gear 455 is coaxially arranged on the first rotating screw 451, and the second bevel gear 455 is meshingly connected with the first bevel gear 454.

[0028] By driving the first rotating motor 452 to work, when the output end of the first rotating motor 452 rotates, it will synchronously drive the connecting shaft 453 to rotate, which will synchronously drive the first bevel gear 454 to rotate, and through the setting of the second bevel gear 455, it will synchronously drive the first rotating screw 451 to rotate, so that the positioning block 41 will synchronously move toward each other, and then the positioning block 41 can be directly driven to move through the operation of the first rotating motor 452, which makes it more convenient and labor-saving during operation.

[0029] Reference Figure 3 and Figure 6 As shown, a flip assembly 46 is provided on the mounting plate 2, and the flip assembly 46 includes a rotating shaft 461, a fixing frame 462 and a fixing block 463; the rotating shaft 461 is provided on the fixing plate 3; the fixing frame 462 is provided on the mounting plate 2; the fixing block 463 is movably provided on the fixing frame 462, and a limiting groove 464 for the fixing block 463 to move is provided on the fixing frame 462, and the fixing block 463 is rotatably connected to the rotating shaft 461.

[0030] By driving the fixing block 463 to rise in the limiting groove 464 of the fixing frame 462, the fixing plate 3 will be driven to rise synchronously. Then, when the fixing block 463 drives the fixing plate 3 to rise to a certain height, the fixing plate 3 is driven to flip so that the fixing plate 3 is perpendicular to the mounting plate 2. Then, through the setting of the rotating shaft 461, the fixing plate 3 can extend the fixing block 463 to flip, and it will not affect the fixing block 463 to rise on the fixing frame 462. When it is necessary to drive the fixing plate 3 to descend, the fixing plate 3 is first driven to flip so that the fixing plate 3 is parallel to the mounting plate 2, and then the fixing block 463 is driven to drive the fixing plate 3 to descend.

[0031] Reference Figure 4 and Figure 5 As shown, a driving part 465 is provided on the mounting plate 2, and the driving part 465 includes a second rotating motor 4651, a second rotating screw 4654, a spur rack 4655 and a rotating wheel 4656; the second rotating motor 4651 is arranged on the mounting plate 2, and a worm 4652 is arranged on the output end of the second rotating motor 4651; the second rotating screw 4654 is arranged on the workbench 1 through a bearing seat, and the second rotating screw 4654 is threadedly connected to the fixed block 463; the spur rack 4655 is arranged on the fixed frame 462; the rotating wheel 4656 is coaxially arranged on the rotating shaft 461, and the rotating wheel 4656 is provided with a first toothed groove 46561 that can mesh with the spur rack 4655.

[0032] By driving the second rotating motor 4651 to work, when the output end of the second rotating motor 4651 rotates, the worm 4652 will be driven to rotate synchronously, so that through the setting of the turbine, the second rotating screw 4654 will be driven to rotate synchronously, so that the fixed block 463 can be raised on the second rotating screw 4654, thereby driving the rotating wheel 4656 to rise, and then when the rotating wheel 4656 rises to a certain height, it will engage with the spur rack 4655, and then through the setting of the first tooth groove 46561 on the rotating wheel 4656, it will drive the rotating shaft 461 to flip ninety degrees, so that the fixed plate 3 can be directly driven to flip ninety degrees synchronously, thereby facilitating the force detection of the automobile interior door panel.

[0033] Reference Figure 4 and Figure 5 As shown, a guide portion 466 is provided on the mounting plate 2, and the guide portion 466 includes a guide frame 4661, a guide block 4662, a guide rack 4665 and a guide wheel 4666; the guide frame 4661 is arranged on the side of the mounting plate 2 away from the fixed frame 462; the guide block 4662 is movably arranged on the guide frame 4661, and a guide groove 4663 for movement of the guide block 4662 is provided on the guide frame 4661, and the guide block 4662 is rotatably connected to the rotating shaft 461; the guide rack 4665 is provided on the guide frame 4661; the guide wheel 4666 is coaxially arranged on the rotating shaft 461, and a second toothed groove 46661 that can mesh with the guide rack 4665 is provided on the guide wheel 4666.

[0034] When the fixing block 463 drives the fixing plate 3 to rise, it will also synchronously drive the guiding block 4662 to rise in the guiding groove 4663 of the guiding frame 4661, thereby providing secondary guiding and limiting functions to the fixing plate 3, so that the fixing plate 3 can be more stable during operation, and through the cooperation between the second toothed groove 46661 on the guiding rack 4665 and the guiding rack 4665, the fixing plate 3 can provide a guiding function again when flipping, thereby further improving the stability of the fixing plate 3 during operation.

[0035] Reference Figure 5 and Figure 6 As shown, the fixed block 463 and the guide block 4662 are both provided with a running wheel 467 , and the running wheel 467 is rotatably connected to the fixed block 463 and the guide block 4662 .

[0036] Since the fixed block 463 and the guide block 4662 move on the fixed frame 462 and the guide frame 4661 respectively, the friction between the fixed block 463 and the guide block 4662 and between the fixed frame 462 and the guide frame 4661 is smaller through the setting of the walking wheel 467, so that the fixed block 463 and the guide block 4662 can move more smoothly on the fixed frame 462 and the guide frame 4661 respectively, thereby extending their service life and improving practicality.

[0037] Reference Figure 2 and Figure 4 As shown, a limiting assembly 21 is provided on the mounting plate 2, and the limiting assembly 21 includes a limiting plate 211 and a positioning pin 212; the limiting plate 211 is provided on the mounting plate 2, and the limiting plate 211 is slidably connected to the workbench 1; the positioning pin 212 is provided on the limiting plate 211, and the working end of the positioning pin 212 can pass through the limiting plate 211 and be plugged into the workbench 1, and a plurality of positioning holes 213 for inserting the positioning pin 212 are provided on the workbench 1.

[0038] When it is necessary to install the automobile interior door panel on the positioning block 41, the positioning pin 212 is inserted into the positioning hole 213 of the workbench 1. In this way, through the setting of the limit plate 211, the mounting plate 2 can be fixed on the workbench 1, making it more convenient to install the automobile interior door panel. Then, when it is necessary to perform a force test on the automobile interior door panel, the mounting plate 2 is pushed to move on the workbench 1 and move to a suitable position, and then the positioning pin 212 is inserted into another positioning hole 213 of the workbench 1, and then the mounting plate 2 is fixed. In this way, the mounting plate 2 can be prevented from moving on the workbench 1 when the detection mechanism 11 performs a force test on the automobile interior door panel, thereby affecting the accuracy of the detection.

[0039] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
