The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0045] Currently, performance testing, noise testing, and life testing of the tailgate strut 100 typically requires preparing a real vehicle's tailgate frame and tailgate, installing the cylinder 101 of the tailgate strut 100 onto the tailgate strut mounting surface of the real vehicle's tailgate frame, and installing the telescopic rod 102 of the tailgate strut 100 onto the tailgate strut mounting surface of the real vehicle's tailgate. The tailgate strut 100 is then tested by opening and closing the tailgate relative to the tailgate frame. This testing method has the following problems: the tailgate strut 100 is inconvenient to assemble and disassemble, occupies a large area, and has high tailgate maintenance costs. Furthermore, it is impossible to test different models of tailgate struts 100 on the same real vehicle's tailgate.

[0046] like Figures 1 to 9As shown, this embodiment provides a tailgate strut test device, which includes a support frame 1 and a test assembly 2, the test assembly 2 includes a swing arm 21, a first connecting member 22, a second connecting member 23 and a driving member 24, one end of the swing arm 21 is pivoted to the support frame 1 through a pivot shaft, the axis of the pivot shaft is set along the first horizontal direction X, the driving member 24 drives the swing arm 21 to swing around the pivot shaft, the first connecting member 22 is set on the support frame 1, and one end of the swing arm 21 is spaced apart from the first connecting member 22 along the vertical direction Z, the second connecting member 23 is fixed to the other end of the swing arm 21, the first connecting member 22 is used to be connected to the cylinder body 101 of the tailgate strut 100 by a ball hinge, and the second connecting member 23 is used to be connected to the telescopic rod 102 of the tailgate strut 100 by a ball hinge, and the swing arm 21 can be telescopic along the length direction of the swing arm 21. When using this device to test a tailgate strut 100, the length of the swing arm 21 is first adjusted according to the model of the tailgate strut 100, so that the cylinder 101 and the telescopic rod 102 are respectively connected to the first connecting member 22 and the second connecting member 23 in a ball-jointed manner. The swing arm 21 is then driven by the driver 24 to swing, simulating the opening and closing of a real vehicle tailgate. The driver 24 varies the driving force to simulate the load and opening and closing speed of different real vehicle tailgates. This device can be used to test the performance, abnormal noise, and life of the tailgate strut 100. It also has the advantages of a small footprint, low maintenance costs, and adaptability to different models of tailgate struts 100.

[0047] Optionally, the driving member 24 includes a motor and a transmission. The driving member 24 is fixed on the support frame 1. The motor, transmission and swing arm 21 are connected in sequence. By changing the torque of the motor, the load and opening and closing speed of different real car tailgates can be simulated.

[0048] Optionally, the tailgate support rod testing device further includes a control module, which is fixed to the support frame 1 and can control the working state of the driving member 24 .

[0049] Optionally, when the tailgate strut 100 is an electric strut, a control harness of the electric strut is connected to a control module, so that the control module can control the operation of the electric strut.

[0050] Optionally, the first connecting member 22 includes a first contouring block 221, a connecting ear 222 and a first ball head 223. The first contouring block 221 is arranged on the support frame 1. The first contouring block 221 is provided with a first contouring surface 2211. The first contouring surface 2211 is used to be parallel to the tailgate support rod mounting surface of the tailgate frame of the actual vehicle. The connecting ear 222 is fixed on the first contouring surface 2211. The connecting ear 222 is fixed with a first ball head 223 on one side along the first horizontal direction X. The cylinder body 101 is recessed with a first ball socket along the first horizontal direction X, and the first ball head 223 is inserted into the first ball socket. In this embodiment, the first contoured surface 2211 on the first contoured block 221 is parallel to the tailgate strut mounting surface of a real vehicle's tailgate frame. This allows the first contoured surface 2211 to mimic the position of the tailgate strut mounting surface of a real vehicle's tailgate frame, thereby ensuring that the cylinder 101's installation on the first contoured surface 2211 produces the same effect as when installed on the tailgate strut mounting surface of a real vehicle's tailgate frame. This improves the accuracy of the strut testing. Furthermore, the first ball head 223 is inserted into the first ball socket, which connects the cylinder 101 to the connecting ear 222 in a spherical hinge. This configuration allows for quick installation of the cylinder 101, thereby improving the installation efficiency of the tailgate strut testing device.

[0051] Optionally, the second connecting member 23 includes a second contoured block 231 and a mounting seat 232. The second contoured block 231 is fixedly mounted to the other end of the swing arm 21. The second contoured block 231 is provided with a second contoured surface 2311, which is parallel to the tailgate strut mounting surface of the actual vehicle tailgate. The mounting seat 232 is fixedly mounted to the second contoured surface 2311 and is configured for a ball-jointed connection with the telescopic rod 102. In this embodiment, the second contoured surface 2311 of the second contoured block 231 is parallel to the tailgate strut mounting surface of the actual vehicle tailgate, so that the second contoured surface 2311 is positioned to mimic the tailgate strut mounting surface of the actual vehicle tailgate. This ensures that the telescopic rod 102 installed on the first contoured surface 2211 achieves the same effect as when installed on the tailgate strut mounting surface of the actual vehicle tailgate. The provision of the first profiling block 221 and the second profiling block 231 ensures that the working environment of the tailgate stay 100 on the testing device is consistent with the working environment on a real vehicle, thereby improving the accuracy of the test.

[0052] Optionally, the mounting seat 232 includes a bottom plate 2321, a second ball head 2322, a limiting pin 2323 and two vertical plates 2324. The bottom plate 2321 is fixed to the second profiling surface 2311. Two vertical plates 2324 are fixed on the side of the bottom plate 2321 away from the second profiling block 231. The two vertical plates 2324 are spaced apart along the swing direction of the swing arm 21 and are surrounded by the bottom plate 2321 to form a U-shaped groove 2327. The second ball head 2322 is set at The groove wall of the U-shaped groove 2327 is opposite to the opening of the U-shaped groove 2327, and the two vertical plates 2324 are respectively provided with two coaxial pin holes at one end away from the bottom plate 2321. The telescopic rod 102 is set in the U-shaped groove 2327, and the second ball head 2322 is inserted into the second ball socket of the telescopic rod 102. The limiting pin 2323 is sequentially passed through the two pin holes, and the limiting pin 2323 abuts against the side of the telescopic rod 102 away from the second ball head 2322. In this embodiment, during the ball-joint connection of the telescopic rod 102 to the mounting base 232, the limiting pin 2323 is first pulled out of the two pin holes. At this time, the telescopic rod 102 can extend from the opening of the U-shaped groove 2327 into the U-shaped groove 2327. Simultaneously, the second ball head 2322 in the U-shaped groove 2327 is inserted into the second ball socket of the telescopic rod 102. The limiting pin 2323 is then sequentially inserted into the two pin holes. This prevents the telescopic rod 102 from being pulled out of the second ball socket, thereby achieving a quick ball-joint connection between the telescopic rod 102 and the mounting base 232. Optionally, the mounting base 232 further includes an elastic member 2326, one end of which is disposed on one vertical plate 2324, the other end of which is disposed on the limiting pin 2323, and one end and the other end of the elastic member 2326 are respectively located on opposite sides of the other vertical plate 2324. This arrangement ensures that the limiting pin 2323 is always inserted into the pin holes of the two vertical plates 2324 under the action of the elastic member 2326.

[0053] Optionally, the swing arm 21 includes a first telescopic rod, a second telescopic rod, and a locking member. One end of the first telescopic rod is pivotally connected to the support frame 1 via a pivot axis. The other end of the first telescopic rod is provided with a sliding hole 441. One end of the second telescopic rod is inserted into the sliding hole 441 and slides with the first telescopic rod. The other end of the second telescopic rod is fixedly connected to the second connecting member 23. The locking member is used to enable the first telescopic rod to have two relative states: sliding and fixed relative to the second telescopic rod. In this embodiment, the first and second telescopic rods slide relative to each other, thereby achieving extension and contraction of the swing arm 21.

[0054] Regarding the specific structure of the locking member, the locking member can optionally be a bolt. A through hole is provided on the peripheral wall of the other end of the first telescopic rod, and a plurality of threaded holes are provided on one end of the second telescopic rod. The plurality of threaded holes are spaced apart along the length of the second telescopic arm. The second telescopic arm slides relative to the first telescopic arm, thereby aligning the through hole with the plurality of threaded holes in sequence. After adjusting the relative positions of the first and second telescopic rods, fine-tuning is performed to align the through hole with one of the plurality of threaded holes. At this point, a bolt is passed through the through hole and threadedly engaged with the corresponding threaded hole, thereby achieving relative fixation of the first and second telescopic rods. In other embodiments, the first telescopic rod and the second telescopic cylinder can be threadedly engaged with each other, or the swing arm 21 can be a telescopic pneumatic cylinder or a hydraulic cylinder.

[0055] Optionally, the tailgate strut test device further includes a support seat 3, which includes a base 31 and a plurality of support wheels 32. The plurality of support wheels 32 are arranged on the bottom wall of the base 31 along the vertical direction Z and are spaced apart around the circumference of the base 31. The support frame 1 is fixed to the top wall of the base 31 along the vertical direction Z. In this embodiment, this arrangement can move the tailgate strut test device as a whole via the support wheels 32, thereby facilitating the transportation of the tailgate strut test device. Specifically, the support wheels 32 are Foma wheels. After being moved to the desired position, the support portion of the Foma wheel can be adjusted so that the Foma wheel supports the base 31 from the rollers to the support portion. The Foma wheel is a prior art and will not be described in detail here.

[0056] Optionally, the tailgate strut testing device further includes a guide assembly 4, which is disposed on a side of the support frame 1 away from the test assembly 2 along the second horizontal direction Y.

The slider 42 is fixed to the base 31, and the first horizontal direction X and the second horizontal direction Y are perpendicular. In this embodiment, the tailgate strut testing device can only slide along the first horizontal direction X under the action of the guide assembly 4. One end of the guide assembly 4 is positioned in a corner. When the tailgate strut testing device is needed, the support base 3 is moved along the first horizontal direction X so that there is space for personnel to move on both sides of the first horizontal direction X, thereby facilitating operation of the test assembly 2. When testing is not needed, the support base 3 can be moved along the first horizontal direction X to a corner, thereby saving a considerable amount of indoor space.

[0057] Optionally, the slide rail 41 includes a base plate 411 and two bearing groups. The base plate 411 is fixed to the ground. The two bearing groups are arranged on the top wall of the base plate 411 and are spaced apart along the second horizontal direction Y. Each bearing group includes a plurality of bearings 412. The plurality of bearings 412 are spaced apart along the first horizontal direction X, and the axes of the bearings 412 are arranged along the vertical direction Z. The slider 42 is inserted between the two bearing groups. In this embodiment, the slider 42 slides between the two bearing groups. The two bearing groups can limit the slider 42 along the second horizontal direction Y. At the same time, this arrangement creates rolling friction between the slider 42 and the bearing groups, thereby reducing the friction between the slider 42 and the slide rail 41 and reducing the labor intensity of the staff.

[0058] Optionally, the slide rail 41 is provided with a plurality of insertion holes 4111 at intervals along the first horizontal direction X. The bottom wall of the base 31 is opposite to the slide rail 41 along the vertical direction Z. The base 31 is provided with a through hole 311 along the vertical direction Z. The support base 3 slides along the first horizontal direction X so that the through hole 311 is sequentially aligned with the plurality of insertion holes 4111. The guide assembly 4 further includes a latch 43 that can pass through the through hole 311 and be selectively inserted into one of the plurality of insertion holes 4111. In this embodiment, when adjusting the position of the support base 3 along the first horizontal direction X, if there is room for staff to move on both sides of the support base 3 along the first horizontal direction X, the support base 3 is fine-tuned so that the through hole 311 on the base 31 is aligned with one of the plurality of insertion holes 4111 on the slide rail 41. At this time, the latch 43 is inserted into the through hole 311 and the corresponding insertion hole 4111, thereby achieving relative fixation between the base 31 and the slide rail 41. Specifically, the plug hole 4111 is located on the substrate 411 .

[0059] Optionally, at least two through-holes 311 are provided on the base 31.

Two latches 43 are provided, and the two latches 43 are respectively inserted into the two through-holes 311 and the two insertion holes 4111 opposite to the two through-holes 311. In this embodiment, this arrangement can improve the stability of the relative fixation between the base 31 and the slide rail 41.

[0060] Optionally, the guide assembly 4 also includes a limit sleeve 44, which is fixed to the upper wall of the base 31, and the sliding hole 441 of the limit sleeve 44 is coaxially arranged with the through hole 311, and a first slide 442 and a second slide 443 that are connected to each other are provided on the peripheral wall of the limit sleeve 44, the first slide 442 extends along the vertical direction Z, and the second slide 443 extends along the circumference of the limit sleeve 44, the latch 43 includes a pin 431 and a limit rod 432, the latch 43 is inserted into the sliding hole 441, the limit rod 432 is fixed to the pin 431 and slides in the first slide 442 and the second slide 443, the limit rod 432 is located in the first slide 442, the pin 431 can be selectively inserted into one of the multiple plug-in holes 4111, the limit rod 432 is located in the second slide 443, and the end of the pin 431 away from the limit sleeve 44 is located in the through hole 311. In this embodiment, the limit rod 432 is fixedly connected to the peripheral wall of the pin 431 and the angle between the pin 431 and the pin 431 is at a right angle. The pin 431 is inserted in the sliding hole 441, and the limit rod 432 extends from the first slide 442 or the second slide 443. The staff can move the limit rod 432 to make the limit rod 432 slide in the first slide 442 and the second slide 443. When the limit rod 432 is in the first slide 442, the limit rod 432 moves along the first slide 442 away from the second slide 443, and then the pin 431 passes through the through hole 311 and is plugged into the corresponding plug-in hole 4111. When the limit rod 432 is in the second slide 443, the end of the pin 431 away from the limit sleeve 44 is located in the through hole 311. At this time, the slider 42 can slide relative to the slide rail 41.
