Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a parameter-adjustable quality detection system for shared electric bicycles. Background Art

[0002] With the widespread adoption of shared electric bicycles, the durability and safety of their key components have become a key focus of the industry. The handlebar, a core component in an electric bicycle's control system, experiences frequent use and complex stress conditions. If performance degradation occurs after prolonged operation, it will directly impact the overall vehicle's handling and safety. Therefore, fatigue testing of electric bicycle handlebars has become a crucial step in product quality testing.

[0003] On the other hand, shared e-bikes often encounter various complex road conditions during actual operation, such as potholes and bumps. The shock resistance of the vehicle and the response of related components under bumpy conditions directly affect its durability and safety.

[0004] However, existing shared electric bicycle testing devices generally have the problem of single function, and are unable to simultaneously perform handlebar fatigue testing and vehicle bump testing on the same test platform. This is because the handlebar fatigue test will cause the front wheel to deflect, and the front wheel needs to be offset from the bump test device during the bump test.

[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, and the rotating tube 33 is rotatably connected to the roller 6. The cylinder 38 and the guide seat 39 are both located in the rotating tube 33. The rotating tube 33 can rotationally support the roller 6, thereby improving the rotation stability of the roller 6.

[0036] According to an optional embodiment of the present invention, a positioning frame 41 is fixed to the inner wall of the bump testing 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 the transmission process, thereby improving the test accuracy.

[0037] According to an optional embodiment of the present invention, the rocker 34 is rotatably connected to the inner wall of the groove 1 31 via a transmission shaft 37 , and the height of the transmission shaft 37 is located at a non-midpoint height on the height of the roller 6 .

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

[0039] According to an optional embodiment of the present invention, a control system is provided on the pedestal 1 to achieve centralized control and parameter adjustment of the entire test process, thereby improving the intelligence level and operational convenience of the system.

[0040] Implementation process: The front and rear wheels of the shared electric bicycle are respectively pressed against the left and right rollers 6, and the two handlebar clamping assemblies 22 are used to clamp the two handlebars on the electric bicycle respectively. The piston rod on the hydraulic cylinder 26 is extended to drive the slide plate 27, spring 28, and pressure piece 29 to move downward, and the pressure piece 29 presses and fixes the seat of the electric bicycle.

[0041] Turn on the servo 20 and the two motors 30. The output shaft of the motor 30 drives the barrel 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 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 vehicle's handlebar to rotate back and forth, and performing a fatigue test on the handlebar. The rotation angle of the handlebar can be adjusted by adjusting the rotation angle of the output shaft of the servo 20.

[0042] The output shaft of the servo 20 will also drive sprocket three 23, chain two 24, sprocket four 25, rotating rod one 9, and bevel gear one 10 to rotate. The bevel gear one 10 drives the bevel gear two 11, rotating rod two 12, sprocket one 13, chain one 14, and sprocket two 15 to rotate. The rotation speed is corrected by the transmission 16. The output shaft of the transmission 16 will drive the bump test device 5 to rotate, so that the rotation amplitude of the bump test device 5 is close to that of the handle, so that the front wheel will not deviate or detach on the roller 6.

[0043] When the bump plate 8 and the wheel collide with each other, it will simulate the bumps on the road, causing the electric bicycle to bump, thereby conducting a bump test of the electric bicycle. When the electric bicycle bumps, the elastic force of spring 19 can provide a buffering function for the handlebar clamping assembly 22, so that the electric bicycle can bump, and the handlebar clamping assembly 22 can keep clamping the handlebars. The elastic force of spring 2 28 can provide a buffering function for the pressing piece 29, so that the electric bicycle can bump, and the pressing piece 29 can keep pressing the seat.

[0044] When the drum 6 rotates, the ball 36 rotates in the guide groove 40. Due to the shape of the guide groove 40, the rocker 34 can be kept from rotating around the transmission shaft 37. Since the height of the transmission shaft 37 is not at the midpoint height of the drum 6, the rocker 34 only rotates around the cylinder shaft 7, which can prevent the bump plate 8 from sliding on the inner wall of the groove 31. Lubricating oil can be applied to the ball 36 regularly to reduce friction.

[0045] When it is necessary to adjust the degree of bumping in the bump test, it is necessary to adjust the length of the bump plate 8 extending outside the roller 6, control the movement of the piston rod on the cylinder 38, thereby driving the guide seat 39 to move, and the inner wall of the guide groove 40 will drive the ball 36 to move, so that the rocker 34 rotates around the transmission shaft 37, so that the transmission roller 35 drives the bump plate 8 to slide along the inner wall of the groove 1 31 by pushing the inner wall of the groove 2 32, thereby completing the adjustment of the length of the bump plate 8 extending outside the roller 6. This design does not require the electric components to be connected to the high-speed rotating roller 6 to cause damage to the electric components. At the same time, there is no need to pause the rotation of the roller 6 to adjust the length of the bump plate 8 extending outside the roller 6, thereby completing the rapid adjustment of the bump degree and improving the test efficiency.

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

[0047] The present invention combines the handlebar fatigue test and the bump test to achieve multiple performance tests of electric bicycles on the same test platform, solving the problem of single function of the test device in the prior art and improving the test 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 preventing the front wheel from deflecting or detaching from the roller 6, and achieving simultaneous handling of the handlebar fatigue test and the bump test.

[0049] By adjusting the hydraulic cylinder 26 and the steering gear 20, the range of motion of the electric bicycle handlebar can be accurately controlled, simulating a real usage environment and improving the accuracy and repeatability of the handlebar 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 anti-seismic performance of the electric bicycle under complex road conditions and ensuring the durability and safety of the entire vehicle;

[0051] The system can precisely adjust the degree of bumping. The test conditions can be adjusted without stopping the rotation of the drum 6, that is, the extension of the bump plate 8 can be adjusted, which greatly improves the flexibility and efficiency of the test. In addition, the electric component is not set in the high-speed rotating drum 6, which prevents damage to the electric component cylinder 38.

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

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
