Description

Technical Field

[0001] This invention relates to the field of scooter strength testing technology, and in particular to a strength testing device for extreme scooter manufacturing. Background Technology

[0002] Extreme roller skating performances have become one of the most popular sports among young people in recent years. They are highly challenging and allow for a full display of individuality, which has not only made roller skating more popular, but also, with skateboarding soon to be an Olympic event, roller skating has gained even more public attention. However, roller skates are classified into street, park, snow, mud and dirt road cross-country, flatland freestyle, and freestyle, depending on the sport they are used in, which places demands on the structural strength of the skateboards.

[0003] To ensure the strength of scooters and meet the requirements of various sports scenarios, strength testing is necessary, especially for the scooter's base and front and rear wheels. However, the current mainstream strength testing method mainly involves single-weight testing with weights of different weights. Since the weights required for scooter strength testing vary, the weights need to be changed frequently, which is cumbersome, time-consuming, and inefficient. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0012] As a preferred embodiment of the strength testing device for extreme scooter processing described in this invention, the supply assembly further includes a cam fixed to the outside of the auxiliary synchronous pulley, a connecting rod hinged to the cam, and a piston that slides with the cylinder barrel hinged to the connecting rod.

[0017] The beneficial effects of this invention are as follows: First, the rolling component simulates three road conditions—dumps, flat roads, and bumps—on the front and rear wheels of the scooter. Then, the detection component, based on a trigger mechanism, continuously controls the counterweight box to perform static and free-fall impact tests on the scooter.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one 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 is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1-9This is the first embodiment of the present invention. This embodiment provides a strength testing device for processing extreme scooters, including a frame 1, a bottom cover 2 fixed to the bottom of the frame 1, a side cover 3 fixed to the outside of the frame 1, a fixing plate 4 disposed inside the frame 1, a cylinder 5 horizontally placed on one side of the fixing plate 4, and a PLC controller fixed to the outside of the frame 1 for driving control of each energized component and normal operation of the overall equipment.

[0033] Specifically, both sides of the fixed plate 4 are provided with rolling components for the front and rear wheels of the scooter, including a servo motor 61 fixed on the other side of the fixed plate 4, a main synchronous wheel 62 sleeved on the output shaft of the servo motor 61, and a secondary synchronous wheel 63 driven by a synchronous belt on the outside of the main synchronous wheel 62. A rotating cylinder 64 that rotates with the fixed plate 4 is fixed inside the main synchronous wheel 62 and the secondary synchronous wheel 63, and the two sets of rotating cylinders 64 are provided with grooves 65 on their circumference.

[0034] The servo motor 61 is turned on and drives the main synchronous pulley 62 to rotate linearly. The main synchronous pulley 62 drives the auxiliary synchronous pulley 63 to rotate synchronously through the synchronous belt. Then, the main synchronous pulley 62 and the auxiliary synchronous pulley 63 drive the two sets of rotating cylinders 64 to rotate synchronously on the fixed plate 4. Subsequently, the two sets of linearly rotating rotating cylinders 64 drive the front and rear wheels of the scooter through the groove 65 to rotate in a simulated pothole road condition scenario.

[0035] Electric push rods 66 are fixed to the outer side of the two sets of rotating cylinders 64, and push-pull seats 67 are fixed to the piston rods of the two electric push rods 66. Support arms 68 are hinged around the two sets of push-pull seats 67, and protrusions 69 that slide through the grooves 65 are hinged to the outer side of the two sets of support arms 68.

[0036] When the two electric push rods 66 are opened simultaneously and the two sets of push-pull seats 67 are moved forward to half their travel, the two sets of push-pull seats 67 drive the two sets of support arms 68 to expand outward. At the same time, the two sets of support arms 68 drive the two sets of protrusions 69 to expand outward within the two sets of rotating cylinders 64 until the two sets of protrusions 69 are exposed and aligned with the two sets of rotating cylinders 64. This forces the linearly rotating two sets of rotating cylinders 64 to drive the front and rear wheels of the scooter to rotate under simulated flat road conditions by passing through the aligned two sets of protrusions 69 and grooves 65.

[0037] Continuing to control the two electric push rods 66 to move the two sets of push-pull seats 67 forward to their final stroke, the two sets of push-pull seats 67 drive the two sets of protrusions 69 through the two sets of support arms 68, which continue to expand outward within the two sets of rotating cylinders 64 until the two sets of protrusions 69 pass through the grooves 65 and are fully exposed, forming protrusions on the two sets of rotating cylinders 64. This forces the linearly rotating two sets of rotating cylinders 64 to drive the front and rear wheels of the scooter to rotate under simulated bumpy road conditions, simulating three road conditions: potholes, flat roads, and bumps, for the front and rear wheels of the scooter. This provides comprehensive road condition testing for the elastic strength of the front and rear wheels of the scooter, making the testing more comprehensive and accurate.

[0038] An electric telescopic rod 11 is fixed on the fixed plate 4, and a front wheel positioning frame 12 for positioning and driving the front wheel of the scooter is fixed on the piston rod of the electric telescopic rod 11. The front wheel positioning frame 12 has an extension frame for positioning the front fork of the scooter, and a rear wheel positioning frame 13 for positioning and driving the rear wheel of the scooter is fixed on the side of the fixed plate 4 away from the electric telescopic rod 11. These components support and position the front and rear wheels, front fork, and mudguards of the scooter to prevent shaking or even tipping during the strength test of the scooter, thereby improving the safety of the strength test. A transmission gap is reserved between the front wheel positioning frame 12 and the rear wheel positioning frame 13 and the front and rear wheels of the scooter to abut and position the mudguards and side frame on the front and rear wheels of the scooter, which is conducive to the normal rotation of the front and rear wheels of the scooter.

[0039] Furthermore, both sides of the bottom of the fixed plate 4 are fixed with slide rails 14, which rotate with the slide rail grooves on the two sets of rotating cylinders 64, providing rotational support for the two sets of rotating cylinders 64 in the rotating state and improving the stability of the two sets of rotating cylinders 64 driving the front and rear wheels of the scooter to rotate.

[0040] Specifically, the frame 1 is equipped with a testing component for scooter strength testing, including a three-stage cylinder 73 located above the frame 1, and a first electrode plate 71 fixed to the outside of two sets of push-pull seats 67. A second electrode plate 72, which is triggered by the first electrode plate 71, is fixed to the inside of two sets of rotating cylinders 64. When the scooter performs the final simulated bumpy road condition scenario, the two sets of push-pull seats 67 complete the entire forward movement and simultaneously drive the two sets of first electrode plates 71 on them to adhere and squeeze into the two sets of second electrode plates 72, thereby triggering the three-stage cylinder 73 to open. This achieves the continuity of the scooter strength testing operation, replacing manual intervention steps and making it more continuous and efficient.

[0041] The circuit breaker 74 is located near the side of the third-stage cylinder 73. An electromagnet base 75 that is energized to and de-energized by the circuit breaker 74 is fixed on the third-stage piston rod of the third-stage cylinder 73. A fixed magnet head 76 is electromagnetically attracted on the electromagnet base 75. A counterweight box 77 is fixed to the bottom of the fixed magnet head 76. Sliding sleeves 78 are fixed at the four corners of the counterweight box 77. A smooth rod 79 fixed to the fixed plate 4 slides in the four sets of sliding sleeves 78. The sliding sleeves 78 and the smooth rod 79 provide limit sliding compensation for the upward movement of the counterweight box 77, improve the stability of the counterweight box 77 before and after lifting, prevent it from tilting and shaking, and ensure that the counterweight box 77 accurately reaches the bottom of the scooter.

[0042] The three-stage cylinder 73 is triggered to open and drive the electromagnet base 75 to move downwards, where it comes into contact with the fixed magnet head 76. Then, the circuit breaker 74 is opened, and the electromagnet base 75 is energized. The energized electromagnet base 75 then electromagnetically attracts the fixed magnet head 76. Subsequently, the three-stage cylinder 73 is controlled to drive the counterweight box 77 to its highest position through the electromagnetically attracted electromagnet base 75 and the fixed magnet head 76. Immediately afterward, the circuit breaker 74 is de-energized to the electromagnet base 75, and the electromagnet base 75 releases its electromagnetic attraction to the fixed magnet head 76. Under the weight of the counterweight box 77 itself, it falls onto the bottom of the scooter in a free-fall posture, and then transmits the impact force to the front and rear wheels of the scooter. Thus, for the scooter on the raised road conditions, the dynamic strength test is completed under the dual action of gravity and the impact force generated by free fall.

[0043] Example 2, refer to Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, the cylinder 5 is equipped with a supply assembly, including a pressure tank 86 fixed to the bottom of the fixed plate 4 with a water supply pipe, a cam 81 fixed to the outside of the auxiliary synchronous pulley 63, a connecting rod 82 hinged to the cam 81, and a piston 83 hinged to the connecting rod 82 that slides with the cylinder 5. The outer end of the cylinder 5 is connected to a pressure pipe 85 through an electronically controlled valve 84 and is unidirectionally connected to the pressure tank 86. The outer end of the pressure tank 86 is connected to a water supply pipe 87, and the outer end of the water supply pipe 87 passes through the fixed plate 4 and is connected to a hose 88. The top end of the hose 88 is connected to a pressurizing angle pipe 89. A storage rack 15 for hiding the hose 88 is fixed on the fixed plate 4 and fixed to the rear wheel positioning frame 13 to store the hose 88 at the counterweight box 77 during the fall to prevent it from affecting the strength test of the scooter.

[0045] The cam 81, which rotates synchronously with the auxiliary synchronous wheel 63, drives the piston 83 to reciprocate within the cylinder 5 via the connecting rod 82. The cam 81 pressurizes and discharges the water pre-filled in the pressurization tank 86 through the pressurization pipe 85 on the electronically controlled valve 84. The water discharged from the pressurization tank 86 is then supplied to the main water distribution pipe 91 on the pressurization angle pipe 89 via the water supply pipe 87 and the flexible hose 88 that moves with the counterweight box 77. The metering valve 95 on the primary water supply head 92, secondary water supply head 93, or tertiary water supply head 94 is then opened accordingly, supplying water of 25 kg, 50 kg, and 100 kg weights into the primary water storage chamber 96, secondary water storage chamber 97, or tertiary water storage chamber 98 of the counterweight box 77, respectively, to meet the precise quantitative weighting requirements of the counterweight box 77 for different weight amounts.

[0046] Specifically, the fixing plate 4 is equipped with a counterweight assembly that can be used to increase or decrease the weight of the detection component. This assembly includes a water distribution main pipe 91 connected to the outer end of the pressurizing angle pipe 89, and a primary water delivery head 92, a secondary water delivery head 93, and a tertiary water delivery head 94 with a metering valve 95 connected to the outer end of the water distribution main pipe 91, as well as a primary water storage chamber 96, a secondary water storage chamber 97, and a tertiary water storage chamber 98 opened in the counterweight box 77, which are connected to the primary water delivery head 92, the secondary water delivery head 93, and the tertiary water delivery head 94 respectively. The outer end of the counterweight box 77 near the primary water storage chamber 96, the secondary water storage chamber 97, and the tertiary water storage chamber 98 is connected to a drain pipe 99 with a one-way valve.

[0047] When the weight of the counterweight box 77 needs to be increased by 25 kg, the metering valve 95 on the primary water supply head 92 is opened, and the metering valves 95 on the secondary water supply head 93 and the tertiary water supply head 94 are closed. Water from the booster tank 86 is then meteredly supplied to the primary water storage chamber 96 within the counterweight box 77 via the primary water supply head 92 opened on the main water distribution pipe 91. Similarly, when the weight of the counterweight box 77 needs to be increased by 50 kg, the metering valve 95 on the secondary water supply head 93 is opened, and the metering valves 95 on the primary water supply head 92 and the tertiary water supply head 94 are closed, continuing to meteredly supply water through the secondary water supply head 93. When the weight of the counterweight box 77 needs to be increased by 100 kg in the secondary water storage chamber 97 inside the counterweight box 77, the tertiary water storage chamber 98 inside the counterweight box 77 is filled with water in a fixed amount. When the weight of the counterweight box 77 is reduced, the one-way valves on the two rows of drain pipes 99 on the outside of the primary water storage chamber 96, the secondary water storage chamber 97 and the tertiary water storage chamber 98 are opened accordingly. The water in the primary water storage chamber 96, the secondary water storage chamber 97 and the tertiary water storage chamber 98 can be discharged separately or simultaneously to reduce the weight. Then, the counterweight box 77 is forced to perform static and dynamic strength testing on the scooter with a gravity of 25 kg, 50 kg and 100 kg.

[0048] Example 3, referring to Figures 1-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, the bottom cover 2 is equipped with a tilting assembly that matches the side cover 3. This assembly includes an angle motor 101 fixed to the outside of the bottom cover 2, a concentric shaft 102 that rotates with the bottom cover 2 fixed on the output shaft of the angle motor 101, and gears 103 sleeved on the concentric shaft 102. Gear frames 104 mesh on the two sets of gears 103 and are fixed to the fixing plate 4. Connecting frames 105 that rotate with the bottom cover 2 are fixed to the outside of the two sets of gear frames 104. A ratchet 106 is sleeved on the outside of the connecting frame 105. A pawl 107 that rotates with the side cover 3 is engaged on the outside of the ratchet 106. Compression springs 108 are fixed to the outside of the two sets of pawls 107 and are fixed to the two sets of side covers 3.

[0050] The control angle motor 101 is turned on and drives two sets of gears 103 to rotate synchronously through the concentric shaft 102. The two sets of gears 103 drive two sets of gear frames 104 to tilt in the same direction. At the same time, the two sets of gear frames 104 drive the ratchet 106 on the two sets of connecting frames 105 to rotate synchronously. The two sets of ratchet 106 drive the two sets of pawls 107 to perform a tooth-skipping action. The two sets of compression springs 108 provide elastic support for the two sets of pawls 107 that are performing the tooth-skipping action. The two sets of ratchet 106 and pawls 107 provide reverse restriction measures for the two sets of gear frames 104 through the two sets of connecting frames 105. The two sets of gear frames 104 rotating in the same direction drive the scooter and its overall components on the fixed plate 4 to tilt at 10 degrees, 20 degrees and 30 degrees in sequence. The counterweight box 77 tilts synchronously and performs a strength test on the tilted scooter again by static and dynamic means.

[0051] Specifically, a limiting slide 16 is fixed on the frame 1, and a limiting slide seat 17 with an alarm light slides on the two sets of limiting slides 16. A support frame 18 is fixed on the inner side of the two sets of limiting slide seats 17 and is fixed to the three-stage cylinder 73 and the circuit breaker 74. The limiting slide 16 and the limiting slide seat 16 play a sliding limiting role for the support frame 18. Then, the fixed plate 4 in the tilted state drives the three-stage cylinder 73 on the support frame 18 to tilt synchronously through the four light rods 79, so as to achieve the overall coordinated effect of the scooter and its components.

[0052] The bottom of the two sets of gear frames 104 is fixed with T-shaped guide rails 19, and the outer side of the two sets of T-shaped guide rails 19 is slidably supported by the support rail seat 20 fixed to the bottom cover 2. This provides rotational support for the two sets of gear frames 104 in the rotating state, improves the rotational stability of the two sets of gear frames 104, prevents them from shaking or tilting, and also provides effective support for the fixed plate 4 on them. The outer side of the two sets of connecting frames 105 is fixed with pointers, and the outer side of the two sets of side covers 3 is provided with angle grooves with fluorescent coating. The pointers are used to read the angle and monitor the tilt angle of the fixed plate 4 in the tilted state.

[0053] The working principle is as follows: First, the scooter to be tested is placed on the fixed plate 4, and the rear wheel of the scooter is abutted in the rear wheel positioning frame 13. After the electric telescopic rod 11 drives the front wheel positioning frame 12 to abut the front wheel of the scooter, the servo motor 61 is turned on and drives the main synchronous wheel 62 to rotate linearly. The main synchronous wheel 62 drives the auxiliary synchronous wheel 63 to rotate synchronously through the synchronous belt. Then, the main synchronous wheel 62 and the auxiliary synchronous wheel 63 drive the two sets of rotating cylinders 64 to rotate synchronously on the fixed plate 4. Subsequently, the two sets of linearly rotating rotating cylinders 64 drive the front and rear wheels of the scooter through the groove 65 to rotate in a simulated pothole road condition scenario.

[0054] Secondly, when simulating flat road conditions, the two electric push rods 66 are opened simultaneously and drive the two sets of push-pull seats 67 to move forward to half their stroke. Then, the two sets of push-pull seats 67 drive the two sets of support arms 68 to expand outward. At the same time, the two sets of support arms 68 drive the two sets of protrusions 69 to expand outward inside the two sets of rotating cylinders 64 until the two sets of protrusions 69 are exposed and remain flush with the two sets of rotating cylinders 64. This forces the linearly rotating two sets of rotating cylinders 64 to drive the front and rear wheels of the scooter to rotate under the simulated flat road conditions through the flushed two sets of protrusions 69 and grooves 65.

[0055] Furthermore, when simulating uneven road conditions, the two electric push rods 66 continue to control the two sets of push-pull seats 67 to move forward to their final stroke. The two sets of push-pull seats 67 then drive the two sets of protrusions 69 through the two sets of support arms 68, which continue to expand outward within the two sets of rotating cylinders 64 until the two sets of protrusions 69 pass through the grooves 65 and are fully exposed, forming protrusions on the two sets of rotating cylinders 64. This forces the linearly rotating two sets of rotating cylinders 64 to drive the front and rear wheels of the scooter to rotate under the simulated uneven road conditions through the two sets of protrusions 69. When the front and rear wheels of the scooter rotate under the simulated uneven and flat road conditions, the counterweight box 77, which loses the electromagnetic attraction of the electromagnet seat 75 to the fixed magnet head 76, is placed statically on the scooter, applying gravity to the scooter under the uneven and flat road conditions, thus completing the static strength test of the scooter.

[0056] When the front and rear wheels of the scooter are simulating bumpy road conditions, the two sets of push-pull seats 67 complete the forward movement of the entire process, and simultaneously drive the two sets of first electrode plates 71 on them to stick and squeeze into the two sets of second electrode plates 72. Then, the three-stage cylinder 73 is triggered to open and drive the electromagnet seat 75 to move down. After it sticks with the fixed magnet head 76, the circuit breaker 74 is controlled to open and the electromagnet seat 75 is energized. After the energized electromagnet seat 75 electromagnetically attracts the fixed magnet head 76, the three-stage cylinder 73 is successively controlled to drive the counterweight box 77 to pull up through the electromagnet seat 75 and the fixed magnet head 76 in the electromagnetic attraction state. The sliding sleeve 78 and the smooth rod 79 provide limit sliding compensation for the upward movement of the counterweight box 77.

[0057] Once the counterweight box 77 has moved to its highest point, the circuit breaker 74 immediately cuts off the power to the electromagnet base 75. The electromagnet base 75 then releases the electromagnetic attraction force on the fixed magnet head 76. Under the weight of the counterweight box 77 itself, it falls onto the bottom of the scooter in a free-fall posture. The impact force is then transmitted to the front and rear wheels of the scooter. Thus, for the scooter on the raised road conditions, the dynamic strength test in the vertical state is completed under the dual action of gravity and the impact force generated by free fall.

[0058] During the static and dynamic strength testing of the scooter, according to the counterweight requirements, the cam 81, which rotates synchronously with the auxiliary synchronous wheel 63, drives the piston 83 to reciprocate in the cylinder 5 via the connecting rod 82. The pressurized water in the pressurization tank 86 is then discharged through the pressurization pipe 85 on the electronic control valve 84. The pressurized water discharged from the pressurization tank 86 is then supplied to the water distribution main pipe 91 on the pressurization angle pipe 89 via the water supply pipe 87 and the flexible hose 88 that moves with the counterweight box 77. The metering valve 95 on the first-stage water supply head 92, the second-stage water supply head 93, or the third-stage water supply head 94 is then opened accordingly, supplying water of 25 kg, 50 kg, and 100 kg weights into the first-stage water storage chamber 96, the second-stage water storage chamber 97, or the third-stage water storage chamber 98 in the counterweight box 77.

[0059] That is, when the weight of the counterweight box 77 needs to be increased by 25 kg, the metering valve 95 on the primary water supply head 92 is opened, and the metering valves 95 on the secondary water supply head 93 and the tertiary water supply head 94 are closed. Then, the water in the booster tank 86 is meteredly supplied into the primary water storage chamber 96 in the counterweight box 77 through the primary water supply head 92 opened on the main water distribution pipe 91, so that the counterweight box 77 is weighed up to 25 kg. Similarly, when the weight of the counterweight box 77 needs to be increased by 50 kg, the metering valve 95 on the secondary water supply head 93 is opened, and the metering valves 95 on the primary water supply head 92 and the tertiary water supply head 94 are closed. Water continues to be meteredly supplied into the secondary water storage chamber 97 in the counterweight box 77 through the secondary water supply head 93, so that the counterweight box 77 is weighed up to 50 kg.

[0060] When the weight of the counterweight box 77 needs to be increased to 100 kg, the three-stage water storage chamber 98 inside the counterweight box 77 is filled with water in a fixed amount to balance the weight of the counterweight box 77 to 100 kg. When the weight of the counterweight box 77 needs to be reduced, the one-way valves on the two rows of drain pipes 99 on the outside of the first-stage water storage chamber 96, the second-stage water storage chamber 97 and the third-stage water storage chamber 98 are opened accordingly. The water in the first-stage water storage chamber 96, the second-stage water storage chamber 97 and the third-stage water storage chamber 98 can be drained separately or simultaneously to reduce the weight. Then, the counterweight box 77 is forced to perform static and dynamic strength tests on the scooter with a gravity of 25 kg, 50 kg and 100 kg.

[0061] When simulating a motion scenario and adjusting the tilt of the scooter, the control angle motor 101 is activated and drives two sets of gears 103 to rotate synchronously via the concentric shaft 102. The two sets of gears 103 drive two sets of gear frames 104 to tilt in the same direction. At the same time, the two sets of gear frames 104 drive the ratchet 106 on the two sets of connecting frames 105 to rotate synchronously. The two sets of ratchet 106 drive the two sets of pawls 107 to perform a skipping action, and the two sets of compression springs 108 provide elastic support for the two sets of pawls 107 that are performing the skipping action. Then, the two sets of ratchet 106 and pawls 107 provide reverse restriction measures for the two sets of gear frames 104 through the two sets of connecting frames 105. The two sets of gear frames 104 rotating in the same direction drive the scooter and its overall components on the fixed plate 4 to tilt at 10 degrees, 20 degrees and 30 degrees in sequence. The counterweight box 77 tilts synchronously to perform a strength test on the tilted scooter again by static and dynamic means.
