Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and particularly to the field of cable chain testing tooling technology, specifically referring to a testing tooling applied to a sliding door cable chain system. Background Technology

[0002] With the development of the new energy vehicle industry, sliding door designs are widely used in this field. A fixture was designed to accurately simulate and test the safety space of key locations and other components during the door opening and closing process. Currently, most industry experimental testing fixtures are driven by multi-axis robotic arms, using servo motor modules to control the motion trajectory, resulting in significant overall costs.

[0003] Therefore, how to provide a new type of testing fixture with a simple structure and low cost has become an urgent problem to be solved in this field. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a test fixture for sliding door cable chain systems that is simple in structure and has a low cost.

[0005] To achieve the above objectives, the test fixture for sliding door cable chain systems of this utility model has the following configuration: The test fixture for the sliding door cable chain system includes a fixture platform 1 and a cable chain fixing mechanism 6 fixed on the fixture platform 1. The cable chain fixing mechanism 6 is used to fix the fixed end of the cable chain to be tested. The fixture platform 1 is also provided with a sliding door curved rail 2 and a guide mechanism 5 that can move along the sliding door curved rail 2. The guide mechanism 5 is used to connect the moving end of the cable chain to be tested. The test fixture also includes a stepper linear motor module 13. The stepper linear motor module 13 is connected to and drives the guide mechanism 5 to reciprocate along the sliding door curved rail 2 to drive the moving end of the cable chain to be tested to simulate the movement process when the sliding door is opened and closed.

[0006] The test fixture for the sliding door cable chain system also includes a linear slide rail 3 set on the fixture table 1 and a vertical guide rail mechanism 4 slidably set on the linear slide rail 3. The guide mechanism 5 is slidably set on the vertical guide rail mechanism 4. The guide mechanism 5 is provided with a movable end connecting plate 7, which is used to connect and fix the moving end of the cable chain to be tested.

[0007] In the test fixture applied to the sliding door drag chain system, the guide mechanism 5 includes a positioning pin 8 and a slider 9. The positioning pin 8 is inserted into the slider 9, and the slider 9 is fixed to the movable end connecting plate 7. The sliding door curved rail 2 is laid above the rail base 10, and a guide groove is opened on the sliding door curved rail 2, so that the positioning pin 8 drives the movable end connecting plate 7 to move along the guide groove along with the slider 9.

[0008] In the test fixture applied to the sliding door cable chain system, the vertical guide rail mechanism 4 includes a slide plate 12 and a slide rail 11. The slide plate 12 is slidably connected to the linear slide rail 3, and the slide rail 11 is disposed on the slide plate 12. The movable end connecting plate 7 is slidably connected to the slide rail 11.

[0009] In the test fixture applied to the sliding door drag chain system, the length direction of the curved sliding door rail 2 is parallel to the linear slide rail 3, and the slide rail 11 is perpendicular to the linear slide rail 3.

[0010] In the test fixture applied to the sliding door drag chain system, the slide plate 12 has a shaft hole on one side, and the shaft hole is connected to the stepper linear motor module 13. The output direction of the stepper linear motor module 13 is consistent with the direction of the linear slide rail 3.

[0011] In the test fixture applied to the sliding door cable chain system, the stepper linear motor module 13 is connected to an external switch cabinet to obtain control commands. The control commands are adjusted by the knob mechanism on the switch cabinet to adjust the moving speed of the moving end of the cable chain under test driven by the drive guide mechanism 5.

[0012] The test fixture for a sliding door cable chain system, employing this utility model, includes a fixture platform, a cable chain fixing mechanism, a sliding door curved rail on the fixture platform, and a guide mechanism that moves along the curved rail. The guide mechanism connects to the moving end of the cable chain under test. The fixture also includes a stepper linear motor module to drive the guide mechanism along the curved rail, simulating the movement of the cable chain under test during the opening and closing of a sliding door. This simulates the operating environment of a vehicle's sliding door and allows observation of any abnormal noises or detachment issues with the cable chain during the simulation. This utility model meets the testing requirements of the cable chain system fixture by converting unidirectional motion driven by a stepper motor into bidirectional motion. The modular arrangement of the mechanism decomposes unidirectional motion into lateral and longitudinal motion, reducing the design and manufacturing costs of the cable chain test fixture and the durability testing costs, thus improving the practicality of the test fixture.

[0015] In order to better understand the technical content of this utility model, the following embodiments are provided for detailed description.

[0016] In one implementation, such as Figures 1 to 3 As shown, the test fixture for the sliding door cable chain system includes a fixture platform 1 and a cable chain fixing mechanism 6 fixed on the fixture platform 1. The cable chain fixing mechanism 6 is used to fix the fixed end of the cable chain to be tested. The fixture platform 1 is also provided with a sliding door curved rail 2 and a guide mechanism 5 that can move along the sliding door curved rail 2. The guide mechanism 5 is used to connect the moving end of the cable chain to be tested. The test fixture also includes a stepper linear motor module 13. The stepper linear motor module 13 is connected to and drives the guide mechanism 5 to reciprocate along the sliding door curved rail 2. The guide mechanism 5 drives the moving end of the cable chain to be tested connected to it to move along a predetermined trajectory, thereby simulating the movement process of the moving end of the cable chain between the starting and ending positions when the sliding door is opened and closed.

[0017] In this embodiment, the test fixture package for the sliding door cable chain system further includes a linear slide rail 3 disposed on the fixture table 1 and a vertical guide rail mechanism 4 slidably disposed on the linear slide rail 3. The guide mechanism 5 is slidably disposed on the vertical guide rail mechanism 4. The guide mechanism 5 is provided with a movable end connecting plate 7, which is used to connect and fix the moving end of the cable chain to be tested.

[0018] In a preferred embodiment, such as Figure 2As shown, the guide mechanism 5 includes a positioning pin 8 and a slider 9. The positioning pin 8 is inserted into the slider 9, and the slider 9 is fixed to the movable end connecting plate 7. The sliding door curved rail 2 is laid above the rail base 10, and a guide groove is formed on the sliding door curved rail 2, so that the positioning pin 8 moves along the movable end connecting plate 7 along the guide groove with the slider 9. The vertical guide rail mechanism 4 includes a slide plate 12 and a slide rail 11. The slide plate 12 is slidably connected to the linear slide rail 3, and the slide rail 11 is disposed on the slide plate 12. The movable end connecting plate 7 is slidably connected to the slide rail 11.

[0019] In a further preferred embodiment, the length direction of the sliding door curved track 2 is parallel to the linear slide rail 3, and the slide rail 11 is perpendicular to the linear slide rail 3.

[0020] In a further preferred embodiment, a shaft hole is provided on one side of the slide plate 12, and the shaft hole is connected to the stepper linear motor module 13. The output direction of the stepper linear motor module 13 is consistent with the direction of the linear slide rail 3.

[0021] In a more preferred embodiment, the stepper linear motor module 13 is connected to an external switch cabinet to obtain control commands. The control commands are then used to adjust the moving speed of the moving end of the drag chain under test by the drive guide mechanism 5 through the knob mechanism on the switch cabinet.

[0022] When actually using the test fixture of this application to test the sliding door cable chain system, the two ends of the cable chain to be tested are respectively installed on the movable end connecting plate 7 and the cable chain fixing mechanism 6. Figure 1 The guide mechanism 5 is positioned in the open state of the sliding door cable chain. The stepper linear motor module 13 drives the vertical guide rail mechanism 4 to move laterally along the linear slide rail 3. The movable end connecting plate 7 drives the guide mechanism 5 to slide along the curved sliding door track 2, allowing the guide mechanism 5 to carry the cable chain along the curved sliding door track 2. When passing through the curved section of the curved sliding door track 2, the movable end connecting plate 7 slides longitudinally along the slide rail 11, cooperating with the sliding plate 12 sliding laterally along the linear slide rail 3, thus decomposing the arc motion of the guide mechanism 5 into horizontal and vertical components. This allows the guide mechanism 5 to move along the curved path of the curved sliding door track 2. The next step is to simulate the entire movement trajectory of the cable chain from the closed state to the open state, until it reaches the desired position. Figure 3 At the position shown, the guide mechanism 5 is reset again by the push of the stepper motor drive module.

[0023] Furthermore, by simulating the closing and opening activities of the cable chain, a cable chain simulation experiment can be completed. Durability testing can be performed as needed. Compared with the working structure driven by a multi-axis robotic arm in traditional experimental testing, this experimental testing fixture has a simple working structure, is easy to disassemble and assemble, has low experimental investment costs, is more flexible in use, and is suitable for interchangeable testing of cable chain system assemblies with different bending radii.

[0024] The test fixture for a sliding door cable chain system, employing this utility model, includes a fixture platform, a cable chain fixing mechanism, a sliding door curved rail on the fixture platform, and a guide mechanism that moves along the curved rail. The guide mechanism connects to the moving end of the cable chain under test. The fixture also includes a stepper linear motor module to drive the guide mechanism along the curved rail, simulating the movement of the cable chain under test during the opening and closing of a sliding door. This simulates the operating environment of a vehicle's sliding door and allows observation of any abnormal noises or detachment issues with the cable chain during the simulation. This utility model meets the testing requirements of the cable chain system fixture by converting unidirectional motion driven by a stepper motor into bidirectional motion. The modular arrangement of the mechanism decomposes unidirectional motion into lateral and longitudinal motion, reducing the design and manufacturing costs of the cable chain test fixture and the durability testing costs, thus improving the practicality of the test fixture.

[0025] In this specification, the present invention has been described with reference to specific embodiments thereof. However, it is obvious that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the specification and drawings should be considered illustrative rather than restrictive, and the scope of protection of this patent is determined by the claims. Any derivative or improved designs based on the technical solution of the present invention are still within the scope of protection of this patent.
