Description

Technical Field

[0001] This invention relates to the field of automotive hinge limiter performance testing technology, specifically to a performance testing platform for automotive hinge limiter production. Background Technology

[0002] In the automotive manufacturing industry, the hinge limiter is a key component ensuring the normal operation and safety of car doors. Its performance directly affects the overall quality of the vehicle and the user experience. During daily driving, car doors are frequently opened and closed. The hinge limiter must not only accurately control the door opening and maintain stability under normal use, but also ensure that the door does not fail due to abnormal force in the event of an unexpected impact, thus ensuring the vehicle's safety performance.

[0003] Currently, performance testing of hinge limiters faces numerous significant challenges. Regarding strength testing, existing testing equipment and methods have significant drawbacks when it's necessary to progressively test the performance of both sides of the hinge limiter. Current procedures often require first removing the limiting device on the hinge limiter, flipping it over, and then re-limiting and fixing it before testing the other side. This process is not only cumbersome and time-consuming, but also highly susceptible to errors due to improper operation during repeated removal and re-limiting, affecting the accuracy and reliability of the test results. This greatly reduces testing efficiency and fails to meet the demands for rapid and accurate product testing in large-scale production.

[0004] Meanwhile, different car models have significant design differences, including varying door heights. However, most existing performance testing platforms lack height adjustment capabilities, making it impossible to flexibly adjust the test platform height according to the door height requirements of different car models. This makes it difficult for testers to find a suitable operating position when testing hinge limiters for various car models, increasing the difficulty of testing operations and severely limiting the versatility and applicability of the testing platform, thus failing to fully adapt to the diverse needs of automobile production. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a performance testing platform for the production of automotive hinge limiters, which can effectively solve the problems of the existing technology, which often requires the removal of the limiting device of the hinge limiter, flipping it over and then re-limiting and fixing it before the testing work on the other side can be carried out, and the lack of height adjustment function of the performance testing platform.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a performance testing platform for the production of automotive hinge limiters, including a mounting box. The upper end of the mounting box is fixedly connected to multiple support rods, and the upper ends of the multiple support rods are jointly fixedly connected to a top plate. A testing component is provided at the lower end of the top plate. A testing platform is provided between the mounting box and the testing component. A height adjustment component for driving the testing platform to rise and fall is provided inside the mounting box. A flipping component is provided at the upper end of the testing platform.

[0008] The height adjustment assembly includes a limiting groove opened in the inner top wall of the mounting box. A first bidirectional threaded rod is rotatably connected in the limiting groove. A first rotary motor for driving the first bidirectional threaded rod is fixedly installed on the inner side wall of the limiting groove. A threaded sleeve block is symmetrically threaded onto the first bidirectional threaded rod. A hinge rod is rotatably connected to the lower end of the threaded sleeve block. A connecting block is rotatably connected to the lower end of the hinge rod. Two lifting rods are symmetrically fixedly connected to the upper end of the connecting block. The upper ends of the plurality of lifting rods pass through the top wall of the mounting box and are fixedly connected to the test platform.

[0009] The flipping assembly includes two fixed plates symmetrically fixedly connected to the upper end of the test platform. A rotating rod is rotatably connected between the two fixed plates. A drive motor for driving the rotating rod to rotate is fixedly installed on one of the fixed plates. The rotating rod is fixedly connected to a mounting frame, and a limit structure is provided in the mounting frame.

[0010] According to the above-mentioned performance testing platform for the production of automotive hinge limiters, the testing component includes a mounting groove opened at the lower end of the testing component, a linear slide rail is provided in the mounting groove, a slider is slidably fitted on the linear slide rail, a mounting base is fixedly connected to the lower end of the slider, and a hydraulic testing machine is fixedly installed at the lower end of the mounting base.

[0011] According to the above-mentioned performance testing platform for the production of automotive hinge limiters, the limiting structure includes two second bidirectional threaded rods symmetrically rotatably connected within a mounting frame. The rods of the two second bidirectional threaded rods are symmetrically fitted with two threaded sleeve plates. The upper end of the testing platform is symmetrically fixedly connected with two support seats, and the upper end surfaces of the two support seats are lower than the lower end surfaces of the two threaded sleeve plates.

[0012] According to the above-mentioned performance test platform for the production of automotive hinge limiters, a sliding cavity is provided at one end of each of the two threaded sleeve plates, a buffer block is slidably connected to the sliding cavity, and a buffer spring is fixedly connected between the buffer block and the sliding cavity.

[0013] According to the above-mentioned performance testing platform for the production of automotive hinge limiters, protective pads are fixedly bonded to the opposite ends of the two buffer blocks.

[0014] According to the above-mentioned performance testing platform for the production of automotive hinge limiters, a second rotary motor for driving one of the second bidirectional threaded rods is fixedly installed on the outer wall of the sliding cavity. Both of the second bidirectional threaded rods are fixedly sleeved with sprockets through the side wall of the mounting frame. The outer sides of the two sprockets are jointly sleeved with a chain. A protective box for protecting the two sprockets and the chain is also provided on the outer side of the mounting frame.

[0015] According to the above-mentioned performance testing platform for the production of automotive hinge limiters, a handle is fixedly connected to the end of the mounting frame away from the rotating rod, and two pads are symmetrically fixedly connected to the side of the mounting frame away from the rotating rod.

[0017] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0018] 1. This invention, by setting up a flipping component, after completing the test on one side, starts the drive motor, and the rotating rod drives the mounting frame and the hinge limiter clamped inside to flip 180 degrees. The pad block and the stabilizing groove cooperate with each other to ensure that it can accurately return to the test position after flipping, reducing errors. This design avoids the complicated operation of repeated disassembly and re-limiting, making the operation simple, greatly saving manpower and time costs, and ensuring the accuracy and reliability of the test results. The test efficiency is high and the accuracy is improved.

[0019] 2. The height adjustment component of this invention starts the first rotary motor, which drives the first bidirectional threaded rod to rotate, causing the threaded sleeve block to slide relative to or opposite to each other in the limiting groove. The connecting block moves up and down through the hinge rod, thereby causing the lifting rod to push the test platform up or down. After adjusting to the appropriate height, the motor stops, and the test platform can be stabilized at the required height. It can easily adapt to the hinge limiter test of different car door heights, greatly improving the versatility and applicability of the test platform, meeting the diverse needs of automobile production. The height is adjustable and highly versatile. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] The present invention will be further described below with reference to embodiments.

[0028] Example: Refer to Figures 1 to 4A performance testing platform for automotive hinge limiter production includes a mounting box 1. Multiple support rods 2 are fixedly connected to the upper end of the mounting box 1. A top plate 3 is fixedly connected to the upper ends of the multiple support rods 2. A testing component 4 is disposed at the lower end of the top plate 3. Specifically, the testing component 4 includes a mounting groove 41 at its lower end. A linear slide rail 42 is disposed within the mounting groove 41, and a slider 43 is slidably fitted onto the linear slide rail 42. A mounting base 44 is fixedly connected to the lower end of the slider 43. A hydraulic testing machine is fixedly mounted at the lower end of the mounting base 44. The hydraulic testing machine is a commonly used device in strength testing, providing stable and adjustable pressure through a hydraulic system. It can precisely control the applied force and simulate the ultimate load that the hinge will withstand during actual use.

[0029] A test platform 5 is provided between the mounting box 1 and the test component 4. The mounting box 1 is provided with a height adjustment component 6 for driving the test platform 5 to rise and fall. Specifically, the height adjustment component 6 includes a limiting groove 61 opened in the inner top wall of the mounting box 1. A first bidirectional threaded rod 62 is rotatably connected in the limiting groove 61. A first rotary motor 63 for driving the first bidirectional threaded rod 62 is fixedly installed on the inner side wall of the limiting groove 61. Threaded sleeve blocks 64 are symmetrically threaded onto the first bidirectional threaded rod 62. The limiting groove 61 is square in shape, and both threaded sleeve blocks 64 slide in cooperation with the limiting groove 61. When the first bidirectional threaded rod 62 rotates, the two threaded sleeve blocks 64 will slide relative to or away from each other along the direction of the limiting groove 61.

[0030] A hinge rod 65 is rotatably connected to the lower end of the threaded sleeve 64. A connecting block 66 is rotatably connected to the lower end of the hinge rod 65. Two lifting rods 67 are symmetrically fixedly connected to the upper end of the connecting block 66. The upper ends of the multiple lifting rods 67 pass through the top wall of the mounting box 1 and are fixedly connected to the test platform 5. When the threaded sleeve 64 slides, the connecting block 66 moves up and down through the transmission of the hinge rod 65, thereby causing the lifting rods 67 to raise or lower the test platform 5. After adjusting to a suitable height, the rotating motor 63 is stopped to ensure that the test platform 5 is stable at the required height for testing hinge limiters that adapt to different car door heights.

[0031] The upper end of the test platform 5 is provided with a flipping component 7. Specifically, the flipping component 7 includes two fixed plates 71 symmetrically fixedly connected to the upper end of the test platform 5. A rotating rod 72 is rotatably connected between the two fixed plates 71. A drive motor for driving the rotating rod 72 is fixedly installed on one of the fixed plates 71. The rotating rod 72 is fixedly connected to a mounting frame 73. After the test on this side is completed, the drive motor installed on the fixed plate 71 is started. The drive motor drives the rotating rod 72 to rotate. The rotating rod 72 drives the mounting frame 73 and the hinge limiter clamped inside to flip 180 degrees. If the drive motor is damaged during the flipping process, the handle 74 on the mounting frame 73 can be held to assist in the rotation.

[0032] A handle 74 is fixedly connected to the end of the mounting frame 73 away from the rotating rod 72. Two pads 75 are symmetrically fixedly connected to the side of the mounting frame 73 away from the rotating rod 72. Two stabilizing grooves 76 are symmetrically opened at the upper end of the test platform 5, which are inserted and cooperate with the pads 75. The pads 75 and the stabilizing grooves 76 cooperate with each other to play a certain positioning and stabilizing role during the flipping process, ensuring that the mounting frame 73 can accurately return to the test position after flipping, reducing errors.

[0033] The mounting frame 73 is provided with a limiting structure 8, which includes two second bidirectional threaded rods 81 that are symmetrically rotatably connected within the mounting frame 73. The rods of the two second bidirectional threaded rods 81 are symmetrically sleeved with two threaded sleeve plates 82. The upper end of the test platform 5 is symmetrically fixedly connected with two support seats 9, and the upper end surfaces of the two support seats 9 are lower than the lower end surfaces of the two threaded sleeve plates 82.

[0034] A second rotary motor for driving one of the second bidirectional threaded rods 81 is fixedly installed on the outer wall of the sliding cavity 83. Both second bidirectional threaded rods 81 pass through the side wall of the mounting frame 73 and are fixedly sleeved with sprockets 86. The outer sides of the two sprockets 86 are jointly sleeved with chains 87. The outer side of the mounting frame 73 is also provided with a protective box 88 for protecting the two sprockets 86 and the chains 87. The car hinge limiter to be tested is placed on the support seat 9 on the test platform 5 so that the center position of the hinge limiter corresponds to the limiting structure 8 in the mounting frame 73.

[0035] Each of the two threaded sleeve plates 82 has a sliding cavity 83 at one end. A buffer block 84 is slidably connected to the sliding cavity 83. A buffer spring 85 is fixedly connected between the buffer block 84 and the sliding cavity 83. When the threaded sleeve plate 82 gradually approaches the hinge limiter, the buffer block 84 contacts the hinge limiter first. During the contact process, the buffer spring 85 will make a certain degree of elastic adjustment according to the outline and placement position of the hinge limiter to ensure that the buffer block 84 can apply pressure evenly and avoid damage to the hinge limiter due to excessive local pressure.

[0036] Protective pads are fixedly bonded to the opposite ends of the two buffer blocks 84. The protective pads fixedly bonded to the opposite ends of the buffer blocks 84 can further protect the surface of the hinge limiter and prevent scratches, wear and other situations from occurring during the clamping process until the two threaded sleeves 82 firmly clamp the hinge limiter, ensuring that the hinge limiter will not be displaced during the test.

[0037] The specific working principle of this invention is as follows:

[0038] When adjusting the height of the test platform 5, when the rotary motor 63 is started, it drives the first bidirectional threaded rod 62 to rotate within the limiting groove 61. Since the threaded sleeve block 64 is threadedly connected to the first bidirectional threaded rod 62 and can only slide within the groove due to the limitation of the limiting groove 61, as the first bidirectional threaded rod 62 rotates, the two threaded sleeve blocks 64 will slide relative to or away from each other according to the rotation direction of the threaded rod. The lower end of the threaded sleeve block 64 is connected to the connecting block 66 through the hinge rod 65. The lifting rod 67 on the connecting block 66 is fixed to the test platform 5. When the threaded sleeve block 64 slides, the hinge rod 65 will drive the connecting block 66 to move up and down, thereby causing the lifting rod 67 to push the test platform 5 to rise or fall, realizing the adjustment of the height of the test platform 5 to adapt to the testing requirements of different vehicle door heights.

[0039] The two second bidirectional threaded rods 81 of the limiting structure 8 rotate synchronously through a sprocket 86 and a chain 87. When the rotary motor installed on the outer wall of the sliding cavity 83 starts, it drives one of the second bidirectional threaded rods 81 to rotate. Through the sprocket and chain drive, the other second bidirectional threaded rod 81 will also rotate synchronously. The two threaded sleeves 82 are threadedly sleeved with the two second bidirectional threaded rods 81 respectively. When the threaded rod rotates, the threaded sleeves 82 will slide relative to or away from each other along the axial direction of the threaded rod. When clamping the hinge limiter, the threaded sleeves 82 slide relative to each other, the buffer block 84 slides in the sliding cavity 83, the buffer spring 85 plays the role of buffering and adaptively adjusting the pressure, and the protective pad prevents damage to the surface of the hinge limiter, thereby achieving stable clamping of the hinge limiter and ensuring that the hinge limiter will not be displaced during the test. Then, it is tested by a hydraulic testing machine.

[0040] After completing the test of one side, when it is necessary to flip the hinge limiter, the drive motor starts, causing the rotating rod 72 to rotate. The mounting frame 73, which is fixedly connected to the rotating rod 72, rotates accordingly, and the hinge limiter clamped in the mounting frame 73 also flips 180 degrees. The cooperation between the pad 75 and the stabilizing groove 76 ensures the accuracy and stability of the position of the mounting frame 73 before and after flipping. Then, by operating the slider 43 to slide on the linear slide rail 42, the test head of the hydraulic tester can be accurately aligned with different test parts of the hinge limiter. The hydraulic tester applies pressure to the hinge limiter according to the set test standards to simulate the force conditions in actual use, thereby testing the performance of the hinge limiter.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
