Description

Technical Field

[0001] The utility model relates to the technical field related to durability testing of front forks of electric vehicles, in particular to a durability testing device for front forks of electric vehicles. Background Art

[0002] The durability test of electric vehicle front forks is an important means of comprehensively evaluating the performance of electric vehicle front forks. As one of the key components of electric vehicles, the electric vehicle front fork bears the important responsibilities of supporting the front weight of the vehicle, buffering road impact, and ensuring driving stability and controllability. The durability test is designed to simulate the various complex working conditions faced by electric vehicle front forks in actual use. Through repeated loading and long-term operation, the reliability and durability of the front fork are verified. During the test, forces of different directions and magnitudes, such as vertical pressure and lateral force, are applied to the front fork to simulate the bumps and corners of the vehicle during driving. At the same time, factors such as different road conditions, loads, and usage environments are also taken into consideration. The electric vehicle front fork durability test, combined with a clamping mechanism, can firmly fix the electric vehicle front fork during the test, ensuring its stable position and preventing it from shifting due to various forces in the test, thereby ensuring the accuracy of the test results. It can adapt to forks of different specifications, improving the versatility of the test equipment. The clamping mechanism also improves the safety of the test and prevents the front fork from accidentally popping out during the durability test, thus ensuring the accuracy of the test results.

[0003] However, the existing electric vehicle front fork durability test equipment does not have a very good clamping stability effect when in use, and when in use, the test rod body is easily damaged during the downward pressure test. Utility Model Content

[0004] The purpose of the utility model is to provide an electric vehicle front fork durability test device to solve the problem that the existing electric vehicle front fork durability test device proposed in the above background technology has a poor clamping stability effect when in use, and is prone to damage to the test rod body during the downward pressure test when in use.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a test device for endurance testing of a front fork of an electric vehicle, comprising a placement plate, a connecting frame, a motor, and a winding drum, wherein the upper surface of the placement plate is mounted with the connecting frame, the upper surface of the connecting frame is mounted with the motor, one side surface of the motor is connected to the winding drum, the inner side surface of the winding drum is connected with a steel rope, one side surface of the steel rope is mounted with a pressure rod, one side of the placement plate is provided with a clamping mechanism, and one side of the placement plate is provided with a protective mechanism;

[0006] The clamping mechanism includes a cylinder, a tooth plate, a gear, a bidirectional threaded rod, a clamping block, a placement groove, a connecting block and a placement block. The cylinder is installed on the upper surface of the placement plate, and the tooth plate is connected to one side surface of the cylinder. A gear is provided on one side surface of the tooth plate. The inner surface of the gear is fixedly connected to the bidirectional threaded rod, and the outer surface of the bidirectional threaded rod is threadedly connected to the clamping block. A placement groove is provided on one side surface of the clamping block.

[0007] Preferably, a connection block is installed on the upper surface of the placement plate, and a placement block is installed on the upper surface of the placement plate.

[0008] Preferably, the steel rope passes through the connecting frame to connect the pressure rod.

[0009] Preferably, the tooth plate moves inside the connecting block.

[0010] Preferably, the clamping blocks are provided in two groups and are symmetrically distributed.

[0011] Preferably, the protective mechanism includes a base plate, a first protective cover, a damping ring, a second protective cover, a connecting pad and a spring. The base plate is installed on the inner surface of the placement plate, the upper surface of the base plate is connected to the first protective cover, the inner surface of the first protective cover is provided with a damping ring, the inner surface of the damping ring is sleeved with a second protective cover, the upper surface of the second protective cover is provided with a connecting pad, and the spring is fixed on one side surface of the connecting pad.

[0012] Preferably, a bottom plate is fixed to the surface of one end of the spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the electric vehicle front fork durability test equipment, the starting cylinder drives the tooth plate to move in the connecting block, and then drives the gear to rotate, so that the bidirectional threaded rod rotates and drives the clamping block to move, and the front frame is clamped by the placement groove, which can ensure that the front frame is firmly fixed in the specified position during the test, and will not be displaced or shaken due to various forces in the test. The starting motor drives the winding disk to rotate, and the steel rope drives the pressure rod to rise and fall in the connecting frame. The combination of the motor and the winding disk can provide, ensuring that the lifting and lowering process of the pressure rod is smooth, thereby accurately evaluating the durability performance of the front fork of the vehicle. When the pressure rod drops to the connecting pad after the test, the connecting pad drives the damping ring to drop in the first protective cover through the second protective cover. The damping ring moves in the first protective cover to generate friction, thereby achieving a damping effect. At the same time, the connecting pad extrusion spring further reduces shock in the first protective cover. This shock absorption and damping design can effectively absorb the impact force generated when the pressure rod drops, reducing vibration and damage to the equipment.
