Description

Technical Field

[0001] This utility model belongs to the field of electric bicycle motor testing technology, specifically relating to a tooling for testing the load performance of hub motors for electric bicycles. Background Technology

[0002] The development of motor testing fixtures stems from advancements in industrial automation and new energy vehicle technology. Early motor testing relied primarily on simple mechanical devices and manual operation, resulting in low accuracy and efficiency. With the development of power electronics, sensor technology, and computer control technology, modern motor testing fixtures have gradually achieved automation and intelligence. They can accurately measure key parameters of motors such as torque, speed, power, and efficiency, and support data acquisition and analysis. In terms of application scenarios, motor testing fixtures are widely used in new energy vehicle drive motors, industrial servo motors, and household appliance motors, covering R&D verification, production quality inspection, and fault diagnosis, providing crucial technical support for motor performance optimization and quality control.

[0003] Traditional tooling relies mainly on manual operation to clamp, position, and connect motors, a process that consumes a significant amount of time. Due to the lack of standardized rapid positioning mechanisms, operators need to repeatedly adjust the motor position to meet testing requirements. This manual intervention not only significantly extends the time for a single test but also makes it difficult to ensure the consistency of clamping positions across multiple tests. In batch testing scenarios, this inefficient manual operation mode accumulates into a serious production bottleneck. Furthermore, clamping errors caused by human factors directly affect the repeatability and accuracy of test data, posing potential risks to product quality control. Utility Model Content

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a load performance testing fixture for a hub motor used in electric bicycles, comprising: The support mechanism 100 includes a support foot 101, a support frame 102 fixedly installed at the end of the support foot 101, a protective shell 103 fixedly installed on the side wall of the support frame 102, a distribution box 104 fixedly connected to the surface of the protective shell 103, and a protective component 105 disposed in the inner cavity of the mounting frame 206a. The testing mechanism 200 includes a connecting seat 201 fixedly connected to the inner cavity of the support frame 102, a guide rail 202 fixedly installed at the bottom of the connecting seat 201, a fixing plate 203 fixedly installed at the end of the guide rail 202, a hydraulic cylinder 204 fixedly installed on the side wall of the fixing plate 203, a moving plate 205 fixedly connected to the end of the hydraulic cylinder 204, a test component 206 disposed on the surface of the moving plate 205, and a moving component 207 disposed on the surface of the support frame 102.

[0019] The protective assembly 105 includes an opening and closing cylinder 105a fixedly installed on the inner wall of the support frame 102, a moving block 105b fixedly installed on the end of the opening and closing cylinder 105a, and a limiting rod 105c slidably connected to the inner wall of the moving block 105b. The protective assembly 105 also includes a sliding door 105d fixedly connected to the side wall of the moving block 105b, a jacking cylinder 105e fixedly installed on the side wall of the support frame 102, and a stop block 105f fixedly installed on the end of the jacking cylinder 105e.

[0020] Furthermore, the end of the limiting rod 105c is fixedly connected to the side wall of the support frame 102. The setting of the limiting rod 105c limits the direction of movement of the moving block 105b, while preventing the moving block 105b from deviating from the predetermined route, ensuring the convenience of the moving block 105b when used in conjunction with the sliding door 105d, and ensuring the protective effect of the sliding door 105d.

[0021] The test assembly 206 includes a mounting bracket 206a fixedly mounted on the surface of the movable plate 205, a load motor 206b adapted to be mounted on the inner wall of the mounting bracket 206a, a clamping cylinder 206c fixedly mounted on the top of the mounting bracket 206a, and a connector 206d fixedly mounted on the end of the clamping cylinder 206c.

[0022] Preferably, the bottom of connector 206d is fixedly connected to the output end of load motor 206b, which facilitates the connection of load motor 206b to the output end of the motor to be tested, and is used in conjunction with clamping cylinder 206c to ensure stable connection.

[0023] The moving component 207 includes a moving cylinder 207a fixedly mounted on the side wall of the support frame 102, and a moving seat 207b fixedly mounted on the end of the moving cylinder 207a. The moving component 207 also includes a fixed seat 207c fixedly mounted on the surface of the moving seat 207b, and a linkage rod 207d connected to the side wall of the fixed seat 207c by a bearing. The moving component 207 also includes a slider 207e connected to the end of the linkage rod 207d by a bearing, and a fixing block 207f movably connected to the surface of the moving seat 207b.

[0024] It should be noted that the surface of the support frame 102 is provided with a slide rail, which is slidably connected to the movable seat 207b. The surface of the movable seat 207b is also provided with a slide rail, which is slidably connected to the slider 207e, to ensure smooth operation of the device.

[0025] In use, the opening / closing cylinder 105a extends, causing the moving block 105b to move upward. The moving block 105b then causes the sliding door 105d to move upward. The moving cylinder 207a extends, causing the moving seat 207b to move. The moving seat 207b moves to the side away from the moving cylinder 207a. When the moving plate 205 is pushed forward, the linkage rod 207d, in conjunction with the housing on the surface of the support frame 102, pushes the linkage rod 207d to both sides. The linkage rod 207d then causes the slider 207e to move to both sides. The output end of the motor to be tested is placed downward on the surface of the moving seat 207b, and the fixing block 207f is engaged. On the surface of the movable seat 207b, the movable cylinder 207a retracts, causing the movable seat 207b to move back to its original position. The sliders 207e on both sides abut against the motor under test. The opening and closing cylinder 105a retracts, causing the sliding door 105d to return to its original position. The hydraulic cylinder 204 extends, causing the load motor 206b on the movable plate 205 to move, bringing the connector 206d against the output end to be tested. The output end of the motor to be tested is connected to the connector 206d. The clamping cylinder 206c runs, fixing the connector 206d. The load motor 206b runs, simultaneously energizing the motor to be tested for load testing.

[0026] In summary, the combined use of the bearing mechanism 100 and the testing mechanism 200 enables efficient and stable testing of the load performance of the hub motor. The protective component 105 in the bearing mechanism 100 automatically opens and closes via the sliding door 105d driven by the opening and closing cylinder 105a, and works in conjunction with the limit rod 105c to ensure precise movement trajectory, effectively protecting personnel and equipment safety during the testing process. The hydraulic cylinder 204 in the testing mechanism 200 drives the load motor 206b to precisely connect to the output end of the motor under test, and the clamping cylinder 206c achieves rapid and stable connection via the connector 206d, ensuring the reliability of the load test. The moving component 207 employs a linkage rod 207d and a slider 207e structure, working with the slide rail to achieve automatic positioning and clamping of the motor under test, simplifying the operation process and improving testing efficiency. The smooth linkage of all components ensures both the accuracy of the test data and the convenience and safety of operation, making it suitable for the batch load performance testing needs of electric bicycle hub motors.
