Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and more specifically to a test device for a simulated car tailgate. Background Technology

[0002] As a key component of modern automotive tailgate systems, the electric tailgate strut (electric strut) directly impacts the safety of tailgate opening and closing, user experience, and overall vehicle quality through its reliability, durability, and operational smoothness. Therefore, rigorous performance and fatigue tests must be conducted on the electric strut during its research, development, production, and quality control to simulate various operating conditions after actual vehicle installation.

[0003] Currently, common testing methods mainly include testing directly on the tailgate of a real vehicle or using simple fixed test benches. While testing on a real vehicle provides realistic conditions, it is limited by specific vehicle models, has poor versatility, and involves long testing cycles, consumes vehicle resources, and is inefficient, making it difficult to meet the needs of multi-variety, batch testing. Existing simple test benches often have fixed structures, with non-adjustable or limited adjustment ranges for mounting points, making them unable to accommodate different models and installation sizes of electric struts. This results in a single set of equipment being able to test only a few specific models, leading to low equipment utilization. Furthermore, existing benches are often inaccurate in simulating the tilt angle and stress state of tailgate opening and closing, especially lacking effective simulation of the locking state when the tailgate is closed and different load conditions. This leads to discrepancies between test data and real vehicle performance, affecting the reliability of test conclusions. Safety during testing is also a prominent issue. If the fixing or locking mechanism is unreliable, it may cause the test piece or simulated tailgate to fall unexpectedly. At the same time, most testing devices are inconvenient to move, hindering their use between different workstations in the production workshop or laboratory. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a simulated tailgate testing device. This simulated tailgate testing device is highly versatile, has a high degree of realism in simulation, is flexible in adjustment, safe and reliable, and easy to move. It can efficiently, accurately, and safely complete comprehensive performance tests of various electric strut products.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A simulated tailgate testing device includes a frame with a testing area. A contour frame is installed within the testing area. One end of the contour frame is hinged to the frame, and the other end is suspended. First mounting seats are provided on both sides of the frame hinged to the contour frame, each with a first connector. A second mounting bracket is installed on the contour frame, with a second connector on the second mounting bracket. The first and second connectors cooperate to mount an electric support rod. An adjustable position structure is provided between the contour frame and the second mounting bracket, allowing for adjustable mounting of the second mounting bracket on the contour frame.

[0006] Furthermore, the frame is provided with first adjustment holes on both sides that are hinged to the profile frame, the first mounting base is provided with a first mounting hole, a first mounting bolt is provided in the first mounting hole, the first mounting bolt passes through the first mounting hole and the first adjustment hole and is fitted with a first nut.

[0007] Furthermore, the position-adjustable structure includes a plurality of second adjustment holes and a second mounting hole. The plurality of second adjustment holes are disposed on the profile frame and arranged along the length direction of the profile frame. The second mounting hole is disposed on the second mounting frame. A second mounting bolt is disposed in the second mounting hole. The second mounting bolt passes through the second mounting hole and the second adjustment hole and is fitted with a second nut.

[0008] Furthermore, the profiling frame is provided with a fitting column, which is arranged perpendicular to the profiling frame.

[0009] Furthermore, a buckle is provided on the side of the frame away from the hinge with the profiling frame in the test area, and a locking mechanism is provided on the end of the profiling frame away from the hinge with the frame, which can cooperate with the buckle to lock.

[0010] Furthermore, the height of the buckle on the frame is lower than the height at which the frame and the profile frame are hinged.

[0011] Furthermore, the bottom of the frame is equipped with several omnidirectional casters.

One end of the contour frame 2 is hinged to the frame 1, and the other end is suspended. A first mounting seat 3 is provided on both sides of the frame 1 where it is hinged to the contour frame 2. A first connector 7 is provided on the first mounting seat 3. A second mounting seat 4 is provided on the contour frame 2. A second connector 8 is provided on the second mounting seat 4.

This allows for flexible adjustment of the position of the first connector 7 according to the installation requirements of different models of electric struts, enhancing the versatility of the testing device and making it easier to adapt to various testing scenarios.

[0024] Preferably, the position adjustable structure includes a plurality of second adjustment holes 201 and a second mounting hole 401. The plurality of second adjustment holes 201 are disposed on the profile frame 2 and arranged along the length direction of the profile frame 2. The second mounting hole 401 is disposed on the second mounting base 4. A second mounting bolt is disposed in the second mounting hole 401. The second mounting bolt passes through the second mounting hole 401 and the second adjustment hole 201 and is fitted with a second nut. Specifically, multiple second adjustment holes 201 are set on the profile frame 2 along its length direction. The second mounting seat 4 is connected to the second adjustment holes 201 at different positions through the second mounting bolts, so as to realize the adjustment of the longitudinal position of the second mounting seat 4 along the profile frame 2. This allows the installation point of the electric strut to be adjusted in multiple levels on the profile frame 2, simulating the actual installation span of the tailgate strut of different vehicle models, and improving the authenticity and coverage of the test.

Specifically, a locking mechanism 6 is provided at the suspension end of the profiling frame 2, which cooperates with the buckle on the frame 1 to achieve mechanical locking of the profiling frame 2 in the closed state; during the test, the profiling frame 2 can be safely fixed to prevent accidental fall that could cause damage to equipment or personnel, while also facilitating preparation before the test and stable parking after the test.

[0027] Preferably, the height of the buckle on the frame 1 is lower than the height at which the frame 1 and the profile frame 2 are hinged; specifically, the buckle position is lower than the hinge axis, so that the profile frame 2 is in a natural tilt or closed posture when locked, which more realistically simulates the force state when the tailgate is closed, improves the accuracy of the test results, and at the same time reduces the force on the buckle and enhances the structural durability.

[0028] Preferably, the bottom of the frame 1 is provided with several universal casters 5, which enable the frame 1 to move as a whole, making it easy for the testing device to move flexibly between different workstations or sites, improving equipment utilization and site adaptability, and taking into account both stability and ease of movement.
