Description

Technical Field

[0001] This invention relates to the field of shock absorber testing technology, and in particular to a device for testing the function of a motorcycle shock absorber. Background Technology

[0002] The field of shock absorber testing technology encompasses technologies related to performance parameter testing, status monitoring, and quality assessment of various shock absorbers. The core of this field involves using a series of technical means to test the working condition of shock absorbers under different operating conditions to determine whether they meet design standards and usage requirements. Overall, it covers the testing of shock absorbers used in various vehicles such as automobiles, motorcycles, and bicycles, involving the testing of multiple indicators such as damping characteristics, rebound performance, and compressive strength. By utilizing mechanical structure design sensing technology and mechanical transmission control, accurate testing of various shock absorber performance parameters is achieved, providing technical support for the production quality control and maintenance of shock absorbers.

[0003] One type of motorcycle shock absorber function testing device refers to equipment specifically designed to test whether a motorcycle shock absorber functions properly. The technical aspects addressed by this patent include testing the expansion and contraction performance of a motorcycle shock absorber under different load conditions, testing the stability of the shock absorber during continuous reciprocating motion, and testing the magnitude of the shock absorber's damping force. Specifically, an adjustable loading mechanism applies different loads to the shock absorber, and a mechanical transmission component drives the shock absorber to reciprocate. Simultaneously, displacement sensors and force sensors are used to detect the expansion and contraction of the shock absorber and the applied force, respectively, thereby completing the function testing of the motorcycle shock absorber.

[0004] Existing technologies apply different loads through adjustable loading mechanisms, with mechanical transmission components driving reciprocating motion and displacement and force sensors detecting relevant data. However, these technologies cannot simulate complex road conditions, adapt to shock absorbers of different lengths and diameters, or simultaneously detect multiple shock absorbers. Furthermore, the force transmission differs from the actual scenario, resulting in limited detection efficiency and accuracy, and failing to fully reflect the performance of shock absorbers in actual use.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1: A motorcycle shock absorber function testing device, see reference. Figure 1 and Figure 2 The device includes an outer shell 1, which effectively isolates noise and vibration during the testing process, ensuring a stable testing environment; a shielding door 3 located on the front of the outer surface of the outer shell 1; a controller 2 located on the outer surface of the shielding door 3, which controls the operation of the entire device and analyzes the testing data; a partition 4 located on the upper part of the inner surface of the outer shell 1, with a testing drive structure 5 fixedly installed on the top wall of the inner cavity of the outer shell 1 on the inner surface of the partition 4; the testing drive structure 5 can apply multi-directional and different frequency forces to the shock absorber; and a shock absorber fixing structure 6 rotatably connected to the middle of the inner cavity of the outer shell 1 through a damping ring; the shock absorber fixing structure 6 can stably fix shock absorbers of different specifications and drive them to rotate to achieve multi-angle testing.

[0033] It should be noted that the controller 2 mentioned above is a conventional control method in the prior art. It uses the principle of electrical on / off control to control the operation of motors, sensors and data transmission. It is a mature technical method in the prior art. Its specific structure, principle and installation method will not be shown or described in detail in this invention.

[0034] In this embodiment, the stable isolation of the detection environment is achieved through the cooperation of the outer shell 1 and the shielding door 3 during operation. The controller 2 can effectively regulate the overall operation and analyze the data. The fixed cylinder 51, rotating disk 52 and sliding column 53 in the detection drive structure 5 cooperate to apply multi-directional and different frequency forces to the shock absorber to simulate complex road conditions. The base plate 61, movable plate 62 and center rod 64 in the shock absorber fixing structure 6 cooperate to adapt to shock absorbers of different lengths. The connecting block 631, clamping component 632 and pressure sensor 633 of the clamping component 63 cooperate to stably clamp from the inside and outside and provide real-time feedback of performance data. The ring distribution design can detect multiple shock absorbers at the same time, improving detection efficiency and accuracy. The swing design of the top plate 65 ensures that the force transmission is more in line with the actual use scenario.

[0035] Example 2: Based on Example 1, this example utilizes the cooperation of the base plate 61, the central rod 64, and the movable plate 62 to adjust the spacing to accommodate shock absorbers of different lengths. The electric turntable design facilitates multi-angle detection. The connecting block 631, the clamping drive component 634, and the clamping component 632 of the clamping assembly 63 cooperate to ensure uniform force distribution on the shock absorber, closely resembling actual installation. The clamping plate 6324 and the inner support plate 6326 are fixed from the inside and outside, improving stability and adapting to different diameters. The pressure sensor 633 can provide real-time performance data feedback. The top plate 65, the central disc 651, and the limiting ball 652 cooperate to ensure more uniform force transmission, simulating bumpy scenarios. The ring-shaped clamping assembly 63 can also detect multiple shock absorbers simultaneously, improving efficiency and detection effect.

[0036] For further details, please refer to [link / reference]. Figure 3 The shock absorber fixing structure 6 includes a base plate 61 rotatably connected to the inner surface of the outer shell 1. The base plate 61 is an electric turntable, which can provide a stable and automatically adjustable rotating foundation for the shock absorber, facilitating testing from different angles. A limiting platform 67 is fixedly installed on the upper end of the base plate 61. A movable plate 62 is slidably connected to the surface of the column of the limiting platform 67. The limiting platform 67 can ensure the stability of the movable plate 62 when sliding. A central rod 64 driven by a motor is rotatably connected to the upper end of the base plate 61. The lower part of the outer surface of the central rod 64 is threaded to the movable plate 62. The threaded groove 66 allows the center rod 64 to rotate, driving the movable plate 62 to slide along the surface of the column of the limiting platform 67, thereby adjusting the distance between the movable plate 62 and the top plate 65 to accommodate shock absorbers of different lengths. The top plate 65 is provided on the upper part of the outer surface of the center rod 64. The outer surface of the top plate 65 and the outer surface of the movable plate 62 are jointly provided with a ring-shaped clamping assembly 63. The ring-shaped clamping assembly 63 can install multiple shock absorbers at the same time, which facilitates multi-angle testing of shock absorbers in the same batch and improves testing efficiency.

[0037] For further details, please refer to [link / reference]. Figure 4The clamping assembly 63 includes two connecting blocks 631 symmetrically distributed vertically. Each connecting block 631 has a clamping drive component 634 on its inner surface, which provides power for the clamping action and enables precise control. Clamping components 632 are located on the sides of the two clamping drive components 634 that are close to each other. The clamping components 632 can directly contact and clamp the shock absorber. The symmetrical distribution of the clamping drive components 634 and clamping components 632 ensures even force distribution on the shock absorber, preventing improper clamping from affecting the test results. The simultaneous vertical clamping method closely resembles the actual installation on a vehicle, making the testing method more realistic and improving the testing effect. Pressure sensors 633 are fixedly mounted on the outer surfaces of both clamping drive components 634. The two pressure sensors 633 are connected via electrical wires and signal lines to the controller 2. During testing, the pressure sensors 633 can detect the shock absorber's performance feedback in real time and transmit the data to the controller 2, providing key parameters for functional testing.

[0038] For further details, please refer to [link / reference]. Figure 5 and Figure 6 The clamping drive component 634 includes an I-beam disc 6343 rotatably connected to the inner surface of the connecting block 631. A knob 6341 is rotatably connected to the inner surface of the I-beam disc 6343. A toothed disc 6345 with staggered tooth depths is formed on the outer surface of the knob 6341. A spring slider 6342 is provided on the inner surface of the I-beam disc 6343, which is in close contact with the central axis of the knob 6341. The spring slider 6342 can ensure the stability of the central axis of the knob 6341 and reduce the shaking during rotation. The inner surface of the I-beam disc 6343 is provided with teeth that engage with the tooth grooves of the toothed disc 6345. The teeth and the toothed disc 6345 form a relative constraint. When the teeth engage with the toothed disc 6345... When the toothed grooves are separated, the I-beam disc 6343 and the connecting block 631 are locked relative to each other. The knob 6341 can be rotated and the relevant components can be adjusted to release or clamp. The inner surface of the I-beam disc 6343 is slidably connected to a trapezoidal block 6346 that is fixedly connected to the toothed disc 6345. The inner surface of the I-beam disc 6343 is slidably connected to a spring locking tongue 6347. The spring locking tongue 6347 slides on the inner wall of the I-beam disc 6343 through a spring. The groove where the spring locking tongue 6347 is located is connected to the outer surface of the I-beam disc 6343. The inner wall of the connecting block 631 is provided with several slots 6311 in a ring shape corresponding to the position of the spring locking tongue 6347.

[0039] When the teeth are in the shallower grooves of the toothed disc 6345, the trapezoidal block 6346 pushes the spring locking tongue 6347 into the slot 6311. At this time, the I-shaped disc 6343 and the connecting block 631 are locked relative to each other, and the knob 6341 cannot be rotated, and the clamping component 632 will not move.

[0040] When the teeth are in the deeper grooves of the toothed disc 6345, the spring locking tongue 6347 separates from the slot 6311. At this time, the I-beam disc 6343 can rotate, but the knob 6341 cannot rotate. The clamping component 632 will not move. However, by rotating the knob 6341 to rotate the shock absorber, the other direction can be detected.

[0041] The inner surface of the knob 6341 is slidably connected to a drive shaft 6344 that drives the clamping component 632. The drive shaft 6344 can transmit the power of the knob 6341 to the clamping component 632 to realize the linkage of clamping action.

[0042] For further details, please refer to [link / reference]. Figure 7 The clamping component 632 includes a positioning plate 6321 fixedly connected to the I-beam plate 6343. The end of the positioning plate 6321 away from the I-beam plate 6343 has annularly distributed arc-shaped grooves 6322. Sliding rods 6323 are slidably connected to the inner surfaces of several arc-shaped grooves 6322. The arc-shaped grooves 6322 provide a stable sliding path for the sliding rods 6323. Clamping plates 6324 are slidably connected to the outer surfaces of several sliding rods 6323 via springs. The springs provide a certain buffer space for the clamping plates 6324 when clamping the shock absorber, preventing damage to the shock absorber while ensuring clamping effectiveness. A drive plate 6325, which is connected to the drive shaft 6344, is provided at the end of the positioning plate 6321 away from the I-beam plate 6343. The sliding rods 6323 are slidably connected to the drive plate 6325. When the drive plate 6325 rotates, it can drive the sliding rods 6323 to slide along the arc-shaped grooves 6322, thereby realizing the opening and closing action of the clamping plates 6324.

[0043] For further details, please refer to [link / reference]. Figure 7 The clamping component 632 also includes a bidirectional screw 6327 fixedly connected to the positioning disk 6321 and rotatably connected to the inner wall of the drive disk 6325. The outer surface of the bidirectional screw 6327 is symmetrically threaded with threaded rings 6328. Several connecting rods are provided on the outer surface of the two threaded rings 6328. The two connecting rods on the same vertical path are rotatably connected to the inner support plate 6326 slidably connected to the drive disk 6325. When the positioning disk 6321 is locked, the bidirectional screw 6327 is locked synchronously. When the drive disk 6325 rotates with the transmission shaft 6344, the threaded rings 6328 slide on the surface of the bidirectional screw 6327, and then drive the inner support plate 6326 to unfold through the connecting rods. The inner support plate 6326 and the clamping plate 6324 cooperate to fix the shock absorber from the inside and outside, which greatly improves the stability of clamping and is suitable for testing shock absorbers of different diameters.

[0044] For further details, please refer to [link / reference]. Figure 8A central plate 651 is fixedly connected to the inner surface of the top plate 65. A limiting ball 652, which is fixedly connected to the central rod 64, is slidably connected to the inner surface of the central plate 651. The cooperation between the limiting ball 652 and the central plate 651 can provide a stable fulcrum for the swing of the top plate 65. The upper end of the top plate 65 is in close contact with the detection drive structure 5. Under the action of the detection drive structure 5, the central plate 651, and the limiting ball 652, the top plate 65 swings around the center of the limiting ball 652. This swing design can transmit the force of the detection drive structure 5 to the shock absorber more evenly, simulating the bumpy situation of a motorcycle.

[0045] In Example 3, based on Example 2, the fixed cylinder 51, rotating disk 52, and sliding column 53 work together to provide a stable foundation for the detection drive. The rotation of the rotating disk 52 can drive the sliding column 53 to move up and down. The drive seat 54 works with the connecting column 56 to drive the rotating disk 52 to swing in a circle around the center point of the spherical concave shape, so that the sliding column 53 pushes the top plate 65, thereby applying forces of different frequencies and directions to the shock absorber. The ball bearings of the sliding column 53 reduce friction, and the spring plate 55 ensures timely reset. The overall structure more comprehensively simulates the complex road conditions of a motorcycle, improving the comprehensiveness and accuracy of the detection.

[0046] For further details, please refer to [link / reference]. Figure 9 and Figure 10 The detection drive structure 5 includes a fixed cylinder 51 fixedly connected to the top wall of the inner cavity of the outer shell 1. The fixed cylinder 51 provides a stable mounting base for the entire detection drive structure 5. Several sliding columns 53 are arranged in an array on the bottom wall of the inner surface of the fixed cylinder 51. The lower ends of the sliding columns 53 extend through the inner wall of the fixed cylinder 51 to the top plate 65. The upper and lower ends of the sliding columns 53 are provided with balls to reduce friction. The balls can reduce the frictional resistance when the sliding columns 53 move, improve the service life and operational stability of the device. The lower part of the outer surface of the sliding columns 53 is fixedly connected to a spring plate 55 fixedly connected to the lower end of the fixed cylinder 51. The spring plate 55 can make the sliding columns 53 return to their original position in time after movement, realizing up and down reciprocating motion. The bottom wall of the inner cavity of the fixed cylinder 51 is rotatably connected to a drive seat 54. The inner surface of the fixed cylinder 51 is provided with a rotating disk 52 for driving the sliding columns 53. The lower end of the rotating disk 52 is in close contact with the friction balls on the upper side of the sliding columns 53. The rotation of the rotating disk 52 can drive the sliding columns 53 to move up and down.

[0047] For further details, please refer to [link / reference]. Figure 10The drive seat 54 is driven by a motor installed at the lower end of the fixed cylinder 51. The upper side of the drive seat 54 is a conical concave surface, and a connecting column 56 is slidably connected to the inclined surface. The side of the connecting column 56 away from the drive seat 54 is fixedly connected to the lower end of the rotating disk 52. The top wall of the inner cavity of the fixed cylinder 51 is a conical convex surface, and a spherical concave surface is set at the conical fixed point. A connecting ball that engages with the spherical concave surface is set at the upper end of the rotating disk 52. This structural design can ensure the stability and accuracy of the rotating disk 52 when it swings. During the rotation of the drive seat 54, the connecting column 56 swings around the axis of the drive seat 54 and drives the rotating disk 52 to swing in a circle with the center point of the spherical concave surface as the center. This drives the sliding column 53 to move up and down and push the top plate 65, so as to apply forces of different frequencies and directions to the shock absorber, and more comprehensively simulate various complex road conditions in motorcycle driving.
