Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, specifically to a scooter strength testing machine and its testing method. Background Technology

[0002] Scooters, as a new and popular mode of transportation, are widely loved. Due to structural limitations, the strength of a scooter directly affects its safety performance. For example, the handlebars and axles of a scooter not only need to withstand the force exerted by the user when operating the scooter, but also the pressure from the user's upper body. If the strength of these components is insufficient, it will cause deformation of the handlebars and axles, as well as damage to the bearings inside the axles. Even a slight deformation can cause a sudden increase in resistance when the rider turns the handlebars, or even make it impossible to complete the steering operation, seriously affecting driving safety. In addition, the load-bearing plate of the scooter directly supports the user's body weight, so its strength testing is equally important.

[0003] Currently, the strength testing of the handlebar and axle connection of scooters is usually done by suspending a heavy object. This method can only perform testing in one direction, resulting in a large error in the test results. Furthermore, when the deformation of the axle is very small, it is not easy to detect by observing the appearance of the axle, making it impossible to automatically determine whether the axle is damaged, which will lead to incorrect test results. The strength of the scooter's load-bearing plate is usually tested by placing a heavy object at a fixed position on the load-bearing plate. Since the test points are all in fixed positions, the test data is limited and the test results have a large error. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a scooter strength testing machine and its testing method, which can effectively solve the problems of single testing direction and large error in existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a scooter strength testing machine, comprising a base plate, a slide rail fixedly mounted on the base plate, and a slide block slidably mounted on the slide rail. The base plate is equipped with a motor, and the machine further includes: A stepping assembly for strength testing of the scooter's support plate includes two upright plates symmetrically arranged on the base plate. Each upright plate has a groove, and a push plate slides along both grooves. Two rotating plates are rotatably inserted into one of the upright plates, penetrating the upright plate. An arc-shaped push plate is hinged to the first rotating plate, and a second rotating plate is hinged to one end of the arc-shaped push plate near the push plate. A push tooth plate and a connecting plate are hinged together on both arc-shaped push plates, with the push tooth plate fitting into the push plate. A pressure gauge is mounted on the push plate, positioned above the support plate. Rotating assembly for rotating the scooter's axle; The pull assembly is used to pull the axle of the scooter.

[0006] Furthermore, the rotating assembly includes a gear box rotatably connected to a base plate. The gear box contains multiple arc-shaped gear blocks and paddles. A support plate is provided on the base plate and is located above the gear box. A rotating shaft is rotatably inserted into the support plate and extends through the support plate into the gear box. A rotating box is provided at one end of the rotating shaft in the gear box, and the rotating box does not contact the gear box. A top gear rod is slidably inserted into the rotating box and is adapted to the arc-shaped gear blocks. A spring is sleeved on the top gear rod. Multiple elastic support rods are fixedly connected to the rotating box. Steel balls are fixedly connected to the elastic support rods and are adapted to iron sheets.

[0007] Furthermore, the rotating assembly also includes an arc-shaped swing rod rotatably connected to the base plate. The end of the arc-shaped swing rod away from the gear box has a swing groove. A turntable is rotatably provided on the support plate, and the diameter of the turntable is smaller than the length of the swing groove. A sliding rod is provided on the turntable near the side, and the sliding rod is slidably connected to the swing groove. The end of the arc-shaped swing rod near the gear box is engaged with the gear box.

[0008] Furthermore, the pulling assembly includes a support plate fixedly connected to the base plate, a spur gear is rotatably inserted into the support plate, a threaded rod is provided at one end of the spur gear near the gear box, a limiting ring is provided on the support plate, an internally threaded tube is slidably connected to the limiting ring, a force sensor is fixedly connected at one end of the internally threaded tube away from the threaded rod, a ball joint connector is fixedly connected at one end of the force sensor, a fixing bracket is provided at one end of the ball joint connector away from the internally threaded tube, and the internally threaded tube is adapted to the threaded rod.

[0009] Furthermore, a clamping seat is fixedly connected to the top of both the rotating shaft and the slide. Two clamping blocks are symmetrically inserted into the clamping seat. A clamping rod is provided at one end of the clamping block near the clamping seat, and the clamping rod passes through the clamping seat and is fitted with a spring.

[0010] Furthermore, the turntable is provided with a spur gear two, and a threaded rod two is rotatably inserted into the support plate, and the threaded rod two extends through the support plate to the support plate. A spur gear three is provided at one end of the threaded rod two near the support plate. A threaded rod three is rotatably provided on the support plate, and both the spur gear two and the spur gear three mesh with the threaded rod three. The threaded rod two meshes with the spur gear one.

[0011] Furthermore, the end of the threaded rod three away from the support plate is provided with a spline, a bevel gear one is slidably provided on the spline, a sliding sleeve is provided on the side of the bevel gear one near the support plate, a spring is sleeved on the spline, a shift fork is rotatably provided on the base plate and the shift fork is adapted to the sliding sleeve, a double-headed bevel gear rod is rotatably provided on the base plate, a bevel gear two is sleeved on the output shaft of the motor, and the bevel gear one and the bevel gear two are rotatably connected by the double-headed bevel gear rod.

[0012] A method for using a scooter strength testing machine includes the following steps: S1: First, move the slide to the position of the scooter's rear wheel, place the scooter's front and rear wheels on the clamp, pull the clamp block to fix the scooter on the clamp, and at the same time fix the scooter's handlebars with the fixing bracket; S2: Secondly, the motor drives the rotation of rotating plate one, which in turn drives another rotating plate one to rotate synchronously through the connecting plate. The rotation of rotating plate one pushes the arc-shaped push plate to move, which in turn drives the toothed plate to reciprocate, thus driving the stepping motion of the push plate. At the same time, the pressure gauge under the push plate presses down on the scooter's load-bearing plate to detect the pressure. Through multiple stepping motions, multiple strength tests on the load-bearing plate are achieved. S3: Again, the motor simultaneously drives the rotation of the double-headed bevel gear rod to drive the threaded rod three, thereby driving the rotation of the arc-shaped swing arm, which in turn drives the gear box to rotate. The rotation of the gear box drives the reciprocating rotation of the shaft rod. At the same time, the rotation of the threaded rod two drives the rotation of the spur gear one, thereby driving the rotation of the threaded rod one, causing the internal threaded tube to move along the limit ring, so that the strength of the scooter's tensile test shaft rod can be tested. The rotation of the shaft rod is combined to achieve multi-angle strength testing. S4: Finally, if the shaft deforms during the rotation and stretching process, it will make it difficult or impossible for the clamp below the shaft to rotate. At this time, the gear box continues to rotate, causing the paddle inside the gear box to rotate and strike the steel ball on the elastic support rod, thus achieving automatic reminder. By rotating the paddle fork, the bevel gear moves along the spline away from the double-headed bevel gear rod, ending the shaft strength test, but without affecting the strength test of the bearing plate.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: This invention incorporates a stepping component that intermittently pushes a pressure gauge to perform multiple strength tests on the scooter's support plate, resulting in more accurate test data. Furthermore, the included rotating and pulling components enable multi-angle strength testing of the scooter's axle, providing richer data and further enhancing accuracy. The rotating component also features an automatic alert mechanism that automatically identifies and alerts the user to potential damage, making the device more intelligent and improving test accuracy. Moreover, the strength testing of the scooter's support plate and axle can be performed simultaneously or separately, increasing the device's convenience. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example: A scooter strength testing machine includes a base plate 1, a slide rail 2 fixedly mounted on the base plate 1, and a slide block 32 slidably mounted on the slide rail 2. A motor 3 is mounted on the base plate 1. The machine also includes: refer to Figures 1-9 The stepping assembly, used for strength testing of the scooter's support plate, includes two upright plates 4 symmetrically arranged on the base plate 1. Each upright plate 4 has a groove 5, and a push plate 6 slides along both grooves 5. Two rotating plates 7 are rotatably inserted into one of the upright plates 4, penetrating the upright plate 4. An arc-shaped push plate 9 is hinged to the rotating plate 7, and a second rotating plate 10 is hinged to the end of the arc-shaped push plate 9 near the push plate 6. A push tooth plate 11 and a connecting plate 8 are hinged together on both arc-shaped push plates 9, and the push tooth plate 11 is adapted to the push plate 6. A pressure gauge 12 is provided on the push plate 6, and the pressure gauge 12 is located above the support plate. A clamping seat 30 is fixedly connected to the top of both the rotating shaft 17 and the slide seat 32. Two clamping blocks 31 are symmetrically inserted into the clamping seat 30. A clamping rod is provided at the end of the clamping block 31 near the clamping seat 30, penetrating the clamping seat 30, and a spring is sleeved on the clamping rod.

[0020] To improve the accuracy of the strength test results, the present invention is equipped with a stepping component, which intermittently pushes the push plate 6 along the slide 5 by pushing the toothed plate 11, and realizes multiple strength tests on the scooter bearing plate by the detection of the pressure gauge 12.

[0021] The specific working process of the stepper component is as follows: First, move the slide seat 32 to the position of the scooter's rear wheel, place the scooter's front and rear wheels onto the clamp seat 30, and fix the scooter onto the clamp seat 30 by pressing the clamping block 31 with the spring sleeved on the clamping rod. The output shaft of the motor 3 is fixedly connected to the rotating plate 7, thereby driving the rotating plate 7 to rotate. When the rotating plate 7 moves upward, it pushes the arc-shaped push plate 9 upward. Since the two arc-shaped push plates 9 are hinged together by the connecting plate 8, the two arc-shaped push plates 9 can move synchronously through the connection of the connecting plate 8. At the same time, the push tooth plate 11 also moves upward, making the movement of the push tooth plate 11 more stable. A rotating plate 2 10 is hinged to one end near the push plate 6. When the rotating plate 2 10 rotates to its highest point, it restricts the upward movement of the push tooth plate 11. When the rotating plate 1 7 continues to rotate, the arc-shaped push plate 9 moves horizontally under the restriction of the rotating plate 2 10, so that the push tooth plate 11 pushes the push plate 6 to slide along the slide groove 5. The spacing of the push tooth plates 11 is adapted to the width of the push plate 6, making the movement of the push plate 6 more stable. As the rotating plate 1 7 continues to rotate, the arc-shaped push plate 9 moves downward and drives the push tooth plate 11 to move downward. At the same time, the pressure gauge 12 on the push plate 6 moves downward to detect the downward pressure strength of the scooter's load-bearing plate. Secondly, as the rotating plate 7 rotates to the lowest point, the arc-shaped push plate 9 and the push tooth plate 11 are both at their lowest positions, but neither is in contact with the scooter's load-bearing plate. As the rotating plate 7 continues to rotate, it intermittently pushes the push plate 6 along the slide 5, causing the pressure gauge 12 to press down on multiple points of the load-bearing plate to perform strength testing. When it is necessary to perform repeated strength testing on the load-bearing plate, when the push plate 6 moves to one end of the slide 5, it is only necessary to rotate the motor 3 in the opposite direction to enable the push plate 6 to continue to perform intermittent strength testing along the slide 5.

[0022] refer to Figures 1-9A rotating assembly is used to rotate the axle of the scooter. The rotating assembly includes a gear box 13 rotatably connected to the base plate 1. The gear box 13 is provided with multiple arc-shaped tooth blocks 14 and iron plates 15. A support plate 16 is provided on the base plate 1, and the support plate 16 is located above the gear box 13. A rotating shaft 17 is rotatably inserted into the support plate 16 and extends through the support plate 16 into the gear box 13. A rotating box 18 is provided at one end of the rotating shaft 17 in the gear box 13, and the rotating box 18 does not contact the gear box 13. A top tooth rod 19 is slidably inserted into the rotating box 18, and the top tooth rod 19 is adapted to the arc-shaped tooth blocks 14. A spring is sleeved on the top tooth rod 19. The rotating box 18 is fixedly connected to... There are multiple elastic support rods 20, and steel balls are fixedly connected to the elastic support rods 20. The steel balls are compatible with the iron sheet 15. The rotating assembly also includes an arc-shaped swing rod 21 rotatably connected to the base plate 1. The end of the arc-shaped swing rod 21 away from the gear box 13 has a swing groove. A turntable 22 is rotatably mounted on the support plate 16. The diameter of the turntable 22 is smaller than the length of the swing groove. A sliding rod is provided on the turntable 22 near the side, and the sliding rod is slidably connected to the swing groove. The end of the arc-shaped swing rod 21 near the gear box 13 meshes with the gear box 13. The pulling assembly is used to pull the axle of the scooter. The pulling assembly includes a support plate 23 fixedly connected to the base plate 1. A spur gear 24 is rotatably inserted into the support plate 23. A threaded rod 25 is provided at one end of the gear box 13 near the gear 24. A limiting ring 26 is provided on the support plate 23. An internally threaded tube 27 is slidably connected to the limiting ring 26. A force gauge is fixedly connected to the end of the internally threaded tube 27 away from the threaded rod 25. A ball joint connector 28 is fixedly connected to one end of the force gauge. A fixing bracket 29 is provided at the end of the ball joint connector 28 away from the internally threaded tube 27. The internally threaded tube 27 is adapted to the threaded rod 25. A spur gear 33 is provided on the turntable 22. A threaded rod 34 is rotatably inserted into the support plate 23 and extends through the support plate 23 to the support plate 16. A spur gear 35 is provided at the end of the threaded rod 34 near the support plate 16. A threaded rod 36 is rotatably mounted on the support plate 16, and both spur gears 33 and 35 mesh with the threaded rod 36. The threaded rod 34 meshes with the spur gear 24. A spline 40 is provided at the end of the threaded rod 36 away from the support plate 23. A bevel gear 41 is slidably mounted on the spline 40. A sliding sleeve 37 is provided on the side of the bevel gear 41 near the support plate 23. A spring is mounted on the spline 40. A shift fork 38 is rotatably mounted on the base plate 1, and the shift fork 38 is adapted to the sliding sleeve 37. A double-headed bevel gear rod 39 is rotatably mounted on the base plate 1. A bevel gear 42 is mounted on the output shaft of the motor 3. The bevel gear 41 and the bevel gear 42 are rotatably connected by the double-headed bevel gear rod 39.

[0023] To further improve the accuracy of the test results, the intelligence of the equipment, and the convenience of the equipment, this invention includes a rotating component and a pulling component. Through the combined action of the pulling component and the rotating component, the scooter axle is rotated and stretched at multiple angles to perform strength testing on the axle. When the axle is deformed, an automatic prompt will be given. Furthermore, the strength testing of the axle can be ended independently without affecting the strength testing of the scooter's load-bearing plate.

[0024] The specific working process of the rotating component and the pulling component is as follows: First, the handlebars of the scooter are fixed to the mounting frame 29. The motor 3 drives the double-headed bevel gear rod 39 to rotate, which in turn drives the bevel gear 41 to rotate, thereby driving the threaded rod 36 to rotate. The rotation of the threaded rod 36 simultaneously drives the spur gear 33 and the spur gear 35. The rotation of the spur gear 33 causes the turntable 22 to rotate. The sliding rod on the turntable 22 slides along the swing groove on the arc-shaped swing rod 21, driving the arc-shaped swing rod 21 to swing back and forth, while simultaneously driving the rotation of the gear box 13. When the shaft is not bent or deformed, the rotational force of the shaft is relatively small. The arc-shaped tooth block 14 inside the gear box 13 will engage with the top tooth rod 19. Since the gear box 13 and the rotating box 18 are not in contact, the transmission is only achieved through the engagement of the arc-shaped tooth block 14 with the top tooth rod 19, thereby driving the rotating box 18. The rotation of the rotating box 18 then drives the clamp 30 to swing back and forth. The movement causes the scooter's axle to swing back and forth. Simultaneously, the rotation of spur gear 35 drives the rotation of threaded rod 34. The rotation of threaded rod 34 synchronously drives spur gear 24, which in turn drives threaded rod 25. Since threaded rod 25 is compatible with internal threaded tube 27 and has a sliding key, internal threaded tube 27 can only move along the limiting ring 26 and cannot rotate. The rotation of threaded rod 25 causes internal threaded tube 27 to move towards spur gear 24. At the same time, the force sensor on internal threaded tube 27 detects the strength of the axle and realizes the rotation of the fixing frame 29 through ball joint connector 28. With the rotation of the axle, the strength of the axle is detected at multiple angles, making the strength detection data richer and further improving the accuracy of the detection results. Secondly, when the shaft is subjected to excessive force and bends, the rotational force of the shaft will suddenly increase, making it difficult or impossible to rotate. At this time, the arc-shaped swing arm 21 continues to drive the gear box 13 to rotate. Since the shaft is deformed and cannot rotate normally, the rotating box 18 on the rotating shaft 17 will also be unable to rotate normally. At this time, the arc-shaped tooth block 14 will press the top tooth rod 19 into the rotating box 18, causing the spring sleeved on the top tooth rod 19 to be compressed, causing the arc-shaped tooth block 14 to disengage from the top tooth rod 19. Since the iron plate 15 and the elastic support rod 20 are matched, that is, at the same height, the iron plate 15 in the gear box 13 will rotate and strike the steel ball on the elastic support rod 20, automatically prompting the inspector that the shaft is bent and deformed, making the equipment more intelligent and further improving the accuracy of the inspection results. Finally, when the bending deformation of the axle cannot be detected for strength testing, if the strength test of the scooter's load-bearing plate has also been completed, the motor 3 can be turned off directly to stop the strength test of the scooter. If the strength test of the scooter's load-bearing plate has not yet been completed, the bevel gear 41 can be moved along the spline 40 towards the spur gear 33 by rotating the shift fork 38, so that the bevel gear 41 disengages from the double-headed bevel gear rod 39 and stops the strength test of the scooter axle. The strength test of the scooter's load-bearing plate can then continue, improving the convenience of the equipment.

[0025] A method for using a scooter strength testing machine includes the following steps: S1: First, move the slide 32 to the position of the rear wheel of the scooter, place the front and rear wheels of the scooter on the clamp 30, pull the clamping block 31 to fix the scooter on the clamp 30, and at the same time fix the handlebar of the scooter with the fixing bracket 29. S2: Secondly, the rotation of motor 3 drives the rotation of rotating plate 7. Rotating plate 7 drives another rotating plate 7 to rotate synchronously through connecting plate 8. The rotation of rotating plate 7 pushes the arc-shaped push plate 9 to move. The arc-shaped push plate 9 drives the push tooth plate 11 to reciprocate, driving the stepping motion of push plate 6. At the same time, the pressure gauge 12 below push plate 6 presses down on the scooter's load-bearing plate to detect the pressure. Through multiple stepping motions, multiple strength tests on the load-bearing plate are achieved. S3: Again, the motor 3 simultaneously drives the rotation of the double-headed bevel gear rod 39 to drive the threaded rod 36, thereby driving the rotation of the arc-shaped swing rod 21, which in turn drives the gear box 13 to rotate. The rotation of the gear box 13 drives the reciprocating rotation of the shaft. At the same time, the rotation of the threaded rod 34 drives the rotation of the spur gear 24, thereby driving the rotation of the threaded rod 25, causing the internal threaded tube 27 to move along the limiting ring 26, so that the strength of the scooter's tensile testing shaft can be tested. The rotation of the shaft can be combined to achieve multi-angle strength testing. S4: Finally, if the shaft deforms during the rotation and stretching process, the clamp 30 below the shaft will have difficulty rotating or will not be able to rotate. At this time, the gear box 13 continues to rotate, causing the iron plate 15 inside the gear box 13 to rotate and strike the steel ball on the elastic support rod 20, thus achieving automatic reminder. By rotating the shift fork 38, the bevel gear 41 moves along the spline 40 away from the double-headed bevel gear rod 39, ending the shaft strength test, but without affecting the strength test of the bearing plate.

7. A scooter strength testing machine according to claim 6, characterized in that, The threaded rod three (36) is provided with a spline (40) at the end away from the support plate (23). A bevel gear one (41) is slidably provided on the spline (40). A sliding sleeve (37) is provided on the side of the bevel gear one (41) near the support plate (23). A spring is sleeved on the spline (40). A shift fork (38) is rotatably provided on the base plate (1), and the shift fork (38) is adapted to the sliding sleeve (37). A double-headed bevel gear rod (39) is rotatably provided on the base plate (1). A bevel gear two (42) is sleeved on the output shaft of the motor (3). The bevel gear one (41) and the bevel gear two (42) are rotatably connected by the double-headed bevel gear rod (39).

8. A testing method applicable to the scooter strength testing machine of claim 7, characterized in that, Includes the following steps: S1: First, move the slide (32) to the position of the rear wheel of the scooter, place the front and rear wheels of the scooter on the clamp (30), pull the clamp block (31) to fix the scooter on the clamp (30), and at the same time fix the handlebar of the scooter with the fixing frame (29); S2: Next, the motor (3) drives the rotation of the rotating plate (7), and the rotating plate (7) drives another rotating plate (7) to rotate synchronously through the connecting plate (8). The rotating plate (7) drives the arc-shaped push plate (9) to move, and the arc-shaped push plate (9) drives the push tooth plate (11) to reciprocate, driving the push plate (6) to step. At the same time, the pressure gauge (12) below the push plate (6) presses down on the scooter's load-bearing plate to detect the pressure. Through multiple step movements, multiple strength tests of the load-bearing plate are achieved. S3: Again, the motor (3) simultaneously drives the rotation of the double-headed bevel gear rod (39) to drive the threaded rod three (36), thereby driving the rotation of the arc-shaped swing rod (21), and then driving the gear box (13) to rotate. Through the rotation of the gear box (13), the shaft rod reciprocates. At the same time, the threaded rod two (34) rotates to drive the spur gear one (24) to rotate, thereby driving the threaded rod one (25) to rotate, so that the internal threaded tube (27) moves along the limiting ring (26), so that the strength of the scooter stretch test shaft rod is tested. The rotation of the shaft rod is combined to realize multi-angle strength testing. S4: Finally, if the shaft deforms during the rotation and stretching process, the clamp (30) below the shaft will have difficulty rotating or will not be able to rotate. At this time, the gear box (13) continues to rotate, causing the iron plate (15) inside the gear box (13) to rotate and strike the steel ball on the elastic support rod (20), thus achieving automatic reminder. By rotating the shift fork (38), the bevel gear one (41) moves along the spline (40) away from the double-headed bevel gear rod (39), ending the shaft strength test, but without affecting the strength test of the bearing plate.
