[0002] Currently, in the research and development and production of vehicles (such as electric bicycles and electric tricycles), the durability of the steering wheel and steering column assembly is an important quality indicator. At present, the sway durability test of this assembly is generally carried out manually. The specific process is as follows: the tester manually and repeatedly turns the vehicle's steering wheel left and right to make the vehicle sway a preset number of times, and then observes the vehicle's rotation and whether there is wear on the wiring harness and pipes related to the sway position, so as to determine whether the vehicle passes the sway durability test.

[0003] Since the above testing process is entirely done manually, it is extremely inefficient, time-consuming and labor-intensive, and the test amplitude and frequency cannot be kept precisely consistent. The test results are highly subjective and cannot guarantee the accuracy of the test results.

[0004] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 3 The present invention provides a vehicle sway durability testing device, which includes a fixed bracket 1, a driving component 2, a transmission component, a sway component, and a clamp 4 for clamping the test piece.

[0035] The drive component 2 is used to drive the swing component to swing back and forth relative to the fixed bracket 1 through the transmission component, so as to drive the test piece on the clamp 4 to swing back and forth.

[0036] In this vehicle sway durability testing device, the operator first clamps and secures the test component (e.g., wheel or steering column) of the vehicle using the clamp 4. Then, the drive unit 2 is activated. The drive unit 2, through a transmission assembly, drives the sway component to oscillate reciprocally relative to the fixed bracket 1, thereby causing the test component on the clamp 4 to oscillate reciprocally. This design achieves complete automation of the testing process, eliminating the need for manual intervention, effectively improving testing efficiency, and ensuring the objectivity and accuracy of the test data.

[0037] It should be noted that the drive component 2 in this embodiment can be specifically selected as an asynchronous motor connected to a frequency converter. By adjusting the speed of the asynchronous motor through the frequency converter, the swing speed can be easily and smoothly adjusted over a wide range to adapt to different test standards.

[0038] In addition, the aforementioned vehicle sway durability testing device adopts reliable mechanical structures such as transmission components and sway components, as well as a reliable asynchronous motor, ensuring that the device can still work stably under long-term, high-intensity reciprocating motion, with virtually no need for mid-term maintenance, which greatly improves testing efficiency and equipment utilization.

[0044] It should be noted that, through the above design, when the test begins, the drive component 2 drives the rotating rod 7 to rotate, thereby causing the connecting rod 8 to drive the rocking rod 9 to swing back and forth relative to the fixed bracket 1.

[0045] Furthermore, in this embodiment, the rocker arm 9 is provided with a plurality of spaced mounting holes 901 along its length direction;

[0046] The second end of the connecting rod 8 is detachably and rotatably connected to one of the mounting holes 901, and the first end of the push-pull rod 3 is detachably and rotatably connected to the other mounting hole 901.

[0047] It should be noted that, in one specific embodiment, the connection end of the push-pull rod 3 and the rocker arm 9 is located above the connection end of the connecting rod 8 and the rocker arm 9.

[0048] In addition, by changing the connection positions of the push-pull rod 3 and the rocker arm 9, as well as the connection position of the connecting rod 8 and the rocker arm 9, the rocking angle of the test piece can be adjusted to meet the testing requirements of different vehicles.

[0049] Furthermore, in this embodiment, the push-pull rod 3 is a push-pull rod 3 with telescopic function.

[0050] It should be noted that in the above design, the clamp 4 is specifically connected to the telescopic end of the push-pull rod 3. By adjusting the telescopic extension of the push-pull rod 3, the swing angle of the test piece can be changed, thereby meeting the testing requirements of different vehicles.

[0051] Furthermore, in this embodiment, the connecting rod 8 is a connecting rod with telescopic function.

[0052] It should be noted that in the above design, the swing angle of the test piece can be changed by extending and retracting the connecting rod 8, thereby meeting the testing requirements of different vehicles.

[0056] In addition, there can be multiple shaft support seats 5, which together support the rotating shaft 6 to ensure that the rotating shaft 6 rotates more smoothly.

[0057] Furthermore, in this embodiment, the clamp 4 can specifically be an adjustable clamp.

[0058] It should be noted that, through the above design, the fixture 4 can clamp and fix test pieces of different sizes, thereby enabling the testing device to test vehicles of different sizes and specifications, which helps to improve the testing range of the testing device.

[0059] In addition, the clamp design allows operators to quickly connect or disconnect the workpiece being tested.

[0060] Furthermore, the vehicle sway durability testing device in this embodiment also includes a counter 12;

[0061] The counter 12 is mounted on the fixed bracket 1 and is used to detect the number of rotations of the rotating rod 7 or the number of swings of the rocking rod 9.

[0062] It should be noted that, through the above design, the counter 12 can accurately count each swing motion, ensuring that the test strictly meets the preset durability cycle requirements.

[0063] Specifically, the counter 12 mentioned above can be a grating sensor or the like, but this embodiment does not limit it.

[0068] Working principle of the vehicle sway durability testing device:

[0069] When the test begins, the operator first clamps the fixture 4 to the test part of the vehicle (such as a wheel or steering column), and then activates the drive unit 2. The drive unit 2 drives the rotating rod 7 to rotate so that the connecting rod 8 drives the rocker arm 9 to swing back and forth relative to the fixed bracket 1, thereby driving the push-pull rod 3 to drive the test part on the fixture 4 to swing back and forth, thus realizing the automated test of the vehicle's swing durability.
