Description

Technical Field

[0001] This invention relates to the field of testing technology, and specifically to a parameter-adjustable quality testing system for shared electric bicycles. Background Technology

[0002] Currently, with the widespread use of shared electric bicycles, the durability and safety performance of their key components have become a major focus of the industry. Among these, the throttle, as one of the core components of the electric bicycle control system, is used frequently and subjected to complex stress states. If its performance deteriorates after prolonged operation, it will directly affect the overall handling performance and safety of the vehicle. Therefore, fatigue testing of electric bicycle throttles has become an important part of product quality inspection.

[0003] On the other hand, shared electric bicycles often face various complex road conditions during actual operation, such as potholes and bumps. The overall shock resistance of the vehicle and the response of related components under bumpy conditions directly affect its durability and safety. Therefore, bump testing has become an important part of the overall testing of electric bicycles.

[0004] However, existing shared electric bicycle testing devices generally have the problem of limited functionality, and cannot simultaneously and effectively perform throttle fatigue testing and whole-vehicle bump testing on the same testing platform. This is because throttle fatigue testing causes the front wheel to deflect, and the front wheel needs to be in contact with the bump testing device during bump testing. The bump testing device cannot shift with the front wheel, causing the front wheel to detach from the bump testing device. Summary of the Invention

[0035] According to an optional embodiment of the present invention, a rotating tube 33 is fixedly connected to the inner wall of the bump testing device 5.

[0036] According to an optional embodiment of the present invention, a positioning frame 41 is fixedly connected to the inner wall of the bump test device 5, and the cylindrical shaft 7 is rotatably connected to the positioning frame 41. The positioning frame 41 improves the coaxiality and rotational stability of the roller 6 during transmission, thereby improving the test accuracy.

[0037] In an optional embodiment of the present invention, the rocker arm 34 is rotatably connected to the inner wall of the groove 31 via a drive shaft 37, the height of which is located at a non-midpoint height of the roller 6.

[0038] According to an optional embodiment of the present invention, the outer wall of the roller 6 is provided with friction texture to increase the friction between the roller 6 and the wheel, prevent the wheel from slipping, ensure good rotational transmission effect, and improve test stability.

[0039] According to an optional embodiment of the present invention, the pedestal 1 is provided with a control system to realize centralized control and parameter adjustment of the entire testing process, thereby improving the intelligence and ease of operation of the system.

[0040] Implementation process: The front and rear wheels of the shared electric bicycle are abutted against the left and right rollers 6 respectively. The two handlebar clamping components 22 are used to clamp the two handlebars on the electric bicycle respectively. The piston rod on the hydraulic cylinder 26 extends, thereby driving the slide plate 27, spring 28 and pressure member 29 to move down. The pressure member 29 presses and fixes the seat of the electric bicycle.

[0041] Turn on the servo motor 20 and the two motors 30. The output shaft of the motor 30 drives the drum shaft 7, the roller 6, and the rotating tube 33 to rotate, thereby driving the front and rear wheels of the electric bicycle to rotate. The output shaft on the servo motor 20 rotates back and forth, thereby driving the connecting rod 21 and the handlebar clamping assembly 22 to rotate back and forth, thereby driving the throttle of the vehicle to rotate back and forth to conduct a fatigue test of the throttle. Adjusting the rotation angle of the output shaft of the servo motor 20 can adjust the rotation angle of the throttle.

[0042] The output shaft of the servo motor 20 also drives the sprocket 3 23, chain 24, sprocket 4 25, lever 1 9, and bevel gear 10 to rotate. Bevel gear 10 drives bevel gear 2 11, lever 2 12, sprocket 1 13, chain 1 14, and sprocket 2 15 to rotate. After the speed is corrected by the gearbox 16, the output shaft of the gearbox 16 drives the bump test device 5 to rotate, so that the rotation amplitude of the bump test device 5 is close to that of the throttle, so that the front wheel will not deviate or detach from the roller 6.

[0043] When the bumper plate 8 comes into contact with the wheel, it simulates bumps on the road, causing the electric bicycle to bounce, thus conducting a bump test on the electric bicycle. When the electric bicycle bounces, the elastic force of spring 19 can provide a buffer function for the handlebar clamp assembly 22, allowing the electric bicycle to bounce, and the handlebar clamp assembly 22 can maintain clamping the handlebars. The elastic force of spring 28 can provide a buffer function for the pressure member 29, allowing the electric bicycle to bounce, and the pressure member 29 can maintain pressing on the seat.

[0044] When the roller 6 rotates, the ball 36 will rotate within the guide groove 40. Due to the shape of the guide groove 40, the rocker arm 34 will not rotate around the drive shaft 37. Since the height of the drive shaft 37 is not at the midpoint of the height of the roller 6, the rocker arm 34 will only rotate around the roller shaft 7, which prevents the bumper plate 8 from sliding on the inner wall of the groove 31. Lubricating oil can be applied to the ball 36 periodically to reduce friction.

[0045] When it is necessary to adjust the degree of bumpiness in the bump test, the length of the bump plate 8 extending beyond the roller 6 needs to be adjusted. The piston rod on the cylinder 38 is controlled to move, thereby driving the guide seat 39 to move. The inner wall of the guide groove 40 will drive the ball 36 to move, thereby causing the rocker arm 34 to rotate around the drive shaft 37. This causes the drive roller 35 to push the inner wall of the second groove 32, thereby driving the bump plate 8 to slide along the inner wall of the first groove 31, completing the adjustment of the length of the bump plate 8 extending beyond the roller 6. This design does not require connecting the electric components to the high-speed rotating roller 6, which would damage the electric components. At the same time, the length of the bump plate 8 extending beyond the roller 6 can be adjusted without stopping the rotation of the roller 6, completing the rapid adjustment of the degree of bumpiness and improving the testing efficiency.

[0046] The present invention has the following beneficial effects:

[0047] This invention combines throttle fatigue testing and bump testing to achieve multiple performance tests of electric bicycles on the same testing platform, solving the problem of single-function testing devices in the prior art and improving testing efficiency.

[0048] Through a series of transmissions, the movement of the bump test device 5 is coordinated with the rotation of the handlebars and the front wheel, effectively avoiding the problem of the front wheel shifting or detaching from the roller 6, and realizing the simultaneous performance of the throttle fatigue test and the bump test.

[0049] By adjusting the hydraulic cylinder 26 and the servo motor 20, the range of motion of the electric bicycle throttle can be precisely controlled, simulating the real usage environment and improving the accuracy and repeatability of the throttle fatigue test.

[0050] The bump test device 5 simulates road bumps through the interaction between the friction roller 6, the bump plate 8 and the wheel, effectively evaluating the shock resistance performance of the electric bicycle under complex road conditions and ensuring the durability and safety of the whole vehicle.

[0051] The system can precisely adjust the degree of bumps without stopping the rotation of the roller 6 to adjust the test conditions, that is, adjust the extension of the bump plate 8, which greatly improves the flexibility and efficiency of the test. Moreover, the electric components are not located inside the high-speed rotating roller 6 to prevent damage to the electric component cylinder 38.

[0052] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
