Description

Technical Field

[0002] There are multiple sets of complex wiring harnesses inside the car. These wiring harnesses are an important part of the vehicle control system. Therefore, durability testing of the wiring inside the car is an indispensable part of the automotive industry's quality control and R&D process. For this reason, wire vibration test benches are often used in daily life to evaluate the performance changes of wires under long-term vibration, thereby ensuring the stability and safety of automotive wires in actual use.

[0003] For example, the patent with publication number CN206787786U specifically discloses an automobile wiring harness vibration test bench. During the test, the vibration motor and the moving motor are started. At this time, the table top of the operating table begins to vibrate under the action of the vibration motor, and the moving rod drives the wiring harness to move left and right along the slide rail under the driving action of the moving motor, thereby simulating the use of the wiring harness in a car driving environment.

[0004] In the above patent, the device is provided with a vibration motor and a moving motor to simulate the vibration generated by the wiring harness during actual use, and then conducts a simulation test. However, since the device only simulates the vibration through two sets of motors during the test, the amplitude of this vibration is relatively single. If the car is driving on a rugged mountain road or other environment, the vibration borne by the wiring harness will also increase accordingly. For this reason, it is necessary to increase the load on the wiring harness to test the load performance of the wiring harness. Therefore, it is necessary to provide a vibration test bench that can add load to the wiring harness to solve the above problem.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0025] like Figure 1-Figure 2 As shown, the present application provides a wire vibration test bench, including a test bench 1, which is set in an automobile processing plant and is used to perform durability tests on the wiring harness inside the automobile. Fixing components 3 are set on both sides of the top of the test bench 1. The fixing components 3 are used to fix the wiring harness to be tested. At the same time, a swinging component 2 is set between the two groups of fixing components 3. The swinging component 2 is used to contact the wiring harness and simulate the vibration caused to the wiring harness when the vehicle is actually driving. At the same time, a control box 11 is also set on the outside of the test bench 1. The control box 11 is used to control the shaking amplitude of the swinging component 2 to simulate road conditions under different environments;

[0026] like Figure 2-Figure 4 As shown, the fixing assembly 3 includes two sets of connecting frames 31, which are respectively installed at the top and bottom of the test bench 1, and a fixing plate 32 is provided on the connecting frame 31. A through hole is provided in the center of the fixing plate 32 for the wiring harness to pass through. At the same time, a clamping joint 33 is provided on the connecting frame 31. One end of the clamping joint 33 is used to clamp the wiring harness to be tested, and the other end is electrically connected to the control box 11. When installing, the wiring harness is passed through the fixing plate 32 and the two ends of the wiring harness are clamped and connected by the two sets of clamping joints 33. At this time, the wiring harness will be electrically connected to the control box 11 for subsequent testing.

[0027] At the same time, a load part 4 is also provided on the wiring harness, which includes a cable tie 41. The cable tie 41 is used to be fixedly installed at any position of the wiring harness. At the same time, a hanging ring 42 is fixedly installed on the outside of the cable tie 41. The center of the hanging ring 42 is set through, and a weight 43 is hung on the hanging ring 42. The weight 43 is used to add load to the wiring harness so as to simulate the load on the wiring harness when the car is actually driving. The size and weight of the weight 43 can be freely adjusted according to the test environment, thereby being able to more realistically reflect the stress state of the wiring harness in actual use.

[0028] like Figure 5-Figure 6 As shown, the swing assembly 2 includes a mounting plate 21 fixedly mounted between two sets of connecting frames 31, a rotating motor 22 is fixedly mounted on the outer side of the mounting plate 21, and the output end of the rotating motor 22 is arranged toward the test bench 1, and a swing portion 5 is provided at the bottom of the rotating motor 22, the swing portion 5 including a test box 51, the test box 51 is fixedly mounted on the mounting plate 21, and the output end of the rotating motor 22 passes through the test box 51 and a connecting rod 52 is fixedly mounted at the bottom, the connecting rod 52 is suitable for rotating under the drive of the rotating motor 22;

[0029] At the same time, a long strip of synchronization block 53 is provided at the bottom of the connecting rod 52, one end of the synchronization block 53 is fixedly connected to the connecting rod 52, and the other end is rotatably installed with a plug-in column 54, and a push plate 6 is fixedly installed at the bottom of the plug-in column 54, and a collision head 61 is provided on both sides of the push plate 6. The collision head 61 is arranged in an arc shape, and a sponge pad is provided inside the collision head 61, which is used to contact the wiring harness.

[0030] During the test, the rotary motor 22 is started to rotate the connecting rod 52, which in turn drives the synchronous block 53 at the bottom to rotate. Since the synchronous block 53 is arranged in an elongated strip, the push plate 6 will swing when the synchronous block 53 rotates. Since there is a certain distance (i.e., eccentricity) between the plug-in column 54 and the output shaft of the connecting rod 52, when the connecting rod 52 rotates, this eccentricity causes the push plate 6 to swing with a larger amplitude, causing the collision head 61 to contact the wiring harness. This swinging mode can simulate the continuous vibration that the wiring harness is subjected to during the driving of the vehicle, providing strong support for the durability and reliability testing of the wiring harness.

[0031] During the test, when the wiring harness is shaken too many times and the internal wires are broken, the resistance received by the control box 11 will increase significantly. At this time, it can be determined that some of the wires in the wire core of the wiring harness are broken, and the tolerance range of the wiring harness can be inferred. Since there are two groups of fixing components 3, when one group of wiring harnesses is broken, the other group of wiring harnesses can continue to be tested.

[0032] In summary, the device increases the test environment of the wire harness by providing the load portion 4, and at the same time, by providing the swing assembly 2, the push plate 6 can simultaneously perform reciprocating collision on two groups of wire harnesses, thereby increasing the test efficiency of the device.

[0033] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
