The electric support rod 40 is hinged to the second adjustment block 11 through a connecting piece passing through the connection holes 111. In this embodiment, the main frame 10 also includes a stopper 13 made of elastic material, and the stopper 13 is connected to the main frame 10. The movable frame 20 rotates close to the main frame 10 until it contacts the stopper 13 to prevent the movable frame 20 from rotating toward the main frame 10.

[0040] Figure 2 Schematic diagram of the structure of the movable frame 20 and the counterweight 30. Figure 1 and Figure 2 As shown, one end of the movable frame 20 is hinged to the main frame 10, and the other end is connected to the tailgate lock 70 facing the main frame 10. The electric support rod 40 is connected between the main frame 10 and the movable frame 20 to push and pull the movable frame 20 to rotate relative to the main frame 10. The movable frame 20 also includes a first adjustment block 14, a first slot body 22, a third slot body 21 and a counterweight block 30. The first slot body 22 and the third slot body 21 extend along the length direction of the movable frame 20, wherein the first slot body 22 is arranged on the side of the movable frame 20 (facing the side of the electric support rod 40), and the third slot body 21 is arranged on the front of the movable frame 20. The first adjustment block 14 is clamped to the first slot body 22, and the electric support rod 40 is connected to the first adjustment block 14. The counterweight block 30 is clamped to the third slot body 21 through a connecting piece to adjust the weight of the movable frame 20.

[0041] Figure 3 It is a structural diagram of the top support mechanism. Figure 3 As shown, the supporting mechanism is provided on the main frame 10, and is used to support the movable frame 20. When the supporting mechanism is extended to support the movable frame 20 so that the tailgate lock 70 is disengaged from the lock buckle 15, the electric support rod 40 pulls the movable frame 20 away from the main frame 10 to rotate. The supporting mechanism includes a driver 50, a supporting rod 51 and a supporting head 52. One end of the supporting rod 51 is connected to the driver 50, and the other end faces the tailgate lock 70 to support the movable frame 20. The supporting head 52 includes an opening 522 arranged in the middle and supporting parts 521 on both sides. When the supporting head 52 supports the tailgate lock 70, the lock buckle 15 is embedded in the opening 522, and the supporting part 521 supports the tailgate lock 70.

[0042] The protection mechanism 60 is connected to the first adjusting block 14 or the second adjusting block 11 . Figure 4Schematic diagram of the structure of the protection mechanism 60. Figure 4 As shown, the protection mechanism 60 includes a fixed plate 61 , a movable plate 62 , a pull rod 65 , a connecting rod 64 , a handle 63 and a blocking rod 66 .

[0043] One end of the fixing plate 61 is connected to the first adjusting block 14 or the second adjusting block 11. In the present application, both ends of the electric support rod 40 are provided with a protection mechanism 60 for preventing the end of the electric support rod 40 from falling out of the first adjusting block 14 or the second adjusting block 11. Figure 4 Taking the protection mechanism 60 connected to the second adjustment block 11 as an example, one end of the fixing plate 61 is connected to the second adjustment block 11 , and the other end extends outward in a direction substantially perpendicular to the second adjustment block 11 .

[0044] The movable plate 62 is movably connected to the fixed plate 61 along the end away from or close to the electric strut 40. Specifically, the side of the fixed plate 61 is provided with a slide groove extending along the length direction of the fixed plate 61, and the movable plate 62 is embedded in the slide groove so that it can slide along the length direction of the slide groove. In this embodiment, the end of the movable plate 62 close to the electric strut 40 can also be connected to a lug 621, and the lug 621 extends toward the direction of the electric strut 40 and blocks the end of the electric strut 40 in parallel with the second adjustment block 11, so that the electric strut 40 is located between the lug 621 and the second adjustment block 11, thereby preventing the end of the electric strut 40 from escaping from the second adjustment block 11. One end of the blocking rod 66 is connected to the movable plate 62, and the other end faces the first adjustment block 14 or the second adjustment block 11. For example Figure 4 The illustrated stop rod 66 extends in the direction of the second adjusting block 11 .

[0045] One end of the pull rod 65 is connected to the movable plate 62, and is movably connected to the fixed plate 61 along the moving direction of the movable plate 62. One end of the connecting rod 64 is hinged to the end of the connecting rod 64, and the other end is hinged to the handle 63. The handle 63 is provided with a protrusion 631, and the protrusion 631 is hinged to the fixed plate 61. When the handle 63 rotates, the handle 63 drives the pull rod 65 to move through the connecting rod 64 to push and pull the movable plate 62 to a position that blocks the end of the electric support rod 40 from coming out.

[0046] When in use, after the start switch of the tailgate lock 70 is triggered, the tailgate lock 70 is unlocked and the lock tongue is retracted. At the same time, the driver 50 controlling the propping mechanism is actuated to drive the propping rod 51 to move toward the tailgate lock 70, so that the top head 52 can quickly hit the tailgate lock 70. At this time, the tailgate lock 70 moves outwards and disengages from the lock buckle 15 under the impact of the top head 52, and is no longer connected to the lock buckle 15 after the lock tongue is reset.

[0047] Then, the electric strut 40 is started, and the electric strut 40 pulls the movable frame 20 to rotate on the main frame 10, simulating the working condition of the electric strut 40 opening the tailgate of the car, and testing the working performance of the electric strut 40 and various functions of the control circuit of the electric strut 40.

[0048] The above-mentioned automobile tailgate electric strut test bench is provided with a supporting mechanism on the main frame 10. When the tailgate lock 70 is unlocked so that the lock tongue of the tailgate lock 70 is retracted, the supporting mechanism is extended to support the movable frame 20 so that the tailgate lock 70 is disengaged from the lock buckle 15. When the lock tongue is reset, it will no longer be connected to the lock buckle 15 of the main frame 10. In this way, the electric strut 40 can pull the movable frame 20 to rotate away from the main frame 10, thereby simulating the working condition of the automobile tailgate electric strut 40.

[0049] In addition, before testing, the positions of the first adjusting block 14 and the second adjusting block 11 can be adjusted to appropriate positions according to the model and specifications (length, force degree, etc.) of the electric strut 40, and then the connecting parts of the first adjusting block 14 and the second adjusting block 11 can be locked to fix the first adjusting block 14, and then the two ends of the electric strut 40 can be respectively fixed to the first adjusting block 14 and the second adjusting block 11 to complete the adjustment of the connection position of the electric strut 40.

[0050] In addition, before and during the test, the position of the counterweight 30 on the movable frame 20 can be adjusted to adjust the center of gravity of the movable frame 20 and the force on the electric strut 40 to achieve the purpose of testing the force performance of the electric strut 40.

[0051] In the several specific embodiments provided, it is obvious that the word "comprising" does not exclude other units or steps, and the singular does not exclude the plural. The words "first", "second", etc. are used to indicate names, but do not indicate any specific order. The above embodiments are only used to illustrate the technical solution rather than to limit it. Although detailed description is made with reference to the above preferred embodiments, a person of ordinary skill in the art should understand that the technical solution can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution.
