Description

Technical Field

[0001] The present invention relates to the technical field of strength detection, in particular to a material strength detection device for an extreme scooter. Background Art

[0002] Skateboarding is a popular sport among young people. Skateboards are typically made of wood or composite materials and can be designed in various shapes and sizes to suit specific needs. The weight and center of gravity can be adjusted to change the state of motion, enabling precise gliding and jumping movements. Skateboard products are gradually developing towards modularity, lightweighting, and diversified functionality. The body of a skateboard, as the core load-bearing component, performs the important functions of supporting the board, steering, and cushioning impacts. The strength and reliability of its material directly impact the user experience and device lifespan.

[0003] A Chinese patent application with publication number CN119000326A discloses a strength testing device for a sports skateboard. This device, which belongs to the field of material testing, includes a strength testing bench with a test tank. The test tank contains multiple sets of two test force cylinders for simulating pulley motion. The two ends of the test force cylinders are connected to load-bearing end seats via a drive device, and the inner wall of the test tank is rotatably connected to the load-bearing end seats via a support member. This invention applies a load and motion state to the sports skateboard while simultaneously applying eccentric rotation of the load-bearing end seats during the testing process, thereby changing the height of the skateboard and generating a height difference. This height difference change causes the pressure acting on the skateboard to change, thereby simulating the process of an athlete jumping on the skateboard and the actual strength change of the skateboard under the action of stress changes, thereby achieving a realistic simulation effect and exploring the impact of the sports skateboard's strength under motion.

[0004] However, the above-disclosed skateboard strength detection device has a single detection mode and cannot simulate different distances between the operator's two feet to perform multiple detections on the board.

When the second testing portion is positioned directly above the test plate, it can press down on both sides of the test plate, simulating an operator's feet stepping on the test plate simultaneously with their feet spread apart. This design improves the practicality and testing effectiveness of the material strength testing device for extreme scooters.

[0019] 3. This invention utilizes a moving frame to automatically unload waste material. After stamping is completed, the lower lifting frame moves downward, causing a linkage gear to engage with the unloading toothed plate, tightening the bandage. Driven by the bandage, the moving frame slides to the sides, allowing the test plate to fall into the storage box below. When the lower lifting frame moves upward, the bandage relaxes, and the elastic member returns the moving frame to its original position. This design enhances the automation level of this material strength testing device for extreme scooters. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the Figures 1 to 8 The technical solutions of the present invention are clearly and completely described. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention provides a material strength detection device for extreme scooters through improvement. Figures 1-8 As shown, it includes a main frame 1, and the internal sliding of the main frame 1 is provided with an upper lifting frame 7 and a lower lifting frame 14 that cooperate with each other; a symmetrical moving frame 30 is movably installed on the top of the lower lifting frame 14, and a unloading cavity 31 is provided in the middle of the moving frame 30, and an installation groove 32 is provided between the moving frames 30, and a plate to be tested 33 is provided in the installation groove 32; when the upper lifting frame 7 moves downward, the lower lifting frame 14 drives the plate to be tested 33 to move upward; a stamping seat 26 is also movably installed on the bottom of the upper lifting frame 7, and the stamping seat 26 includes a first detection part 27 and a second detection part 28 with a staggered design. When the vertical position of the stamping seat 26 relative to the plate to be tested 33 is adjusted, the detection mode is adjusted; when the upper lifting frame 7 moves upward, the lower lifting frame 14 drives the plate to be tested 33 to move downward after the detection is completed. At this time, the moving frame 30 slides to both sides and realizes automatic unloading of the plate to be tested 33.

[0033] In this embodiment, the material strength testing device for extreme scooters consists of three main components: an upper lifting frame 7, a lower lifting frame 14, and a punching base 26. During use, the test plate 33 is first placed in the mounting slot 32. As the upper lifting frame 7 moves downward, the lower lifting frame 14 drives the test plate 33 upward. While the first detection portion 27 on the punching base 26 contacts and punches the test plate 33, the second detection portion 28, located within the blanking chamber 31, does not interfere with the punching process. As the upper lifting frame 7 moves upward, the lower lifting frame 14 drives the tested plate 33 downward. During this movement, the linkage gear 36 engages the blanking tooth plate 22, tightening the bandage 38. Driven by the bandage 38, the moving frame 30 slides sideways, stretching the elastic member 35 and allowing the test plate 33 to fall into the storage box 39 below. When another set of test panels 33 needs to be tested, the lower lifting frame 14 moves upward and the moving frame 30 moves toward the middle and returns to its original position, and then the new test panels 33 are placed in the mounting slots 32 .

[0034] See attached Figure 1 -Attached Figure 5 A symmetrical through cavity 3 is provided on the top of the main frame 1, and symmetrical swing cavities 6 are provided on both sides of the main frame 1; a symmetrical fixed pendulum seat 2 is provided on the top of the main frame 1, and a linkage swing arm 13 is movably installed on the fixed pendulum seat 2, and a symmetrical moving pendulum seat 11 is provided on the top of the upper lifting frame 7, and an active swing arm 12 is movably installed on the moving pendulum seat 11, and the top of the active swing arm 12 is movably connected to the inner side of the linkage swing arm 13; sliding arms 15 are provided on both sides of the lower lifting frame 14, and a mounting seat 16 located in the swing cavity 6 is provided on the outer wall of the sliding arm 15, and a driven swing arm 17 is movably installed on the mounting seat 16, and the top of the driven swing arm 17 is movably connected to the outer side of the linkage swing arm 13.

[0035] In this embodiment, when the upper lifting frame 7 moves downward, the active swing arm 12 moves downward, pulling the interlocking swing arm 13 downward. The outer side of the interlocking swing arm 13 is now higher than the inner side, and under the action of the driven swing arm 17, the lower lifting frame 14 drives the test plate 33 upward. When the upper lifting frame 7 moves upward, the active swing arm 12 moves upward, lifting the interlocking swing arm 13 upward. The outer side of the interlocking swing arm 13 is now lower than the inner side, and under the action of the driven swing arm 17, the lower lifting frame 14 drives the test plate 33 downward after testing.

[0036] See attached Figure 3 -Attached Figure 4 and attached Figure 7 A first slide groove 5 is provided on the inner walls on both sides of the main frame 1, and a first boss 8 slidably arranged in the first slide groove 5 is provided on both sides of the upper lifting frame 7 and the lower lifting frame 14.

[0037] In this embodiment: when the upper lifting frame 7 and the lower lifting frame 14 reciprocate up and down along the inner wall of the main frame 1, in order to further improve the stability during movement, a first sliding groove 5 and a first boss 8 structure that cooperate with each other are designed.

[0038] See attached Figure 1 -Attached Figure 4 A horizontal slide 9 is movably installed inside the upper lifting frame 7, and an eccentric cylinder 10 is movably provided in the middle of the horizontal slide 9; a suspension 20 is also provided on the top of the main frame 1, and a stamping motor 21 is installed on the suspension 20, and the output end of the stamping motor 21 is movably connected to the eccentric cylinder 10.

[0039] In this embodiment: when the punching motor 21 drives the eccentric cylinder 10 to rotate, since the eccentric cylinder 10 is movably arranged in the middle of the horizontal slide 9, the horizontal slide 9 will convert the rotation of the eccentric cylinder 10 into an up and down reciprocating motion of the upper lifting frame 7.

[0040] See attached Figure 4 -Attached Figure 5 A second slide groove 18 is provided on the inner walls of the upper and lower sides of the upper lifting frame 7, and a second boss 19 is provided on the upper and lower sides of the horizontal slide 9.

[0041] In this embodiment, when the horizontal slide 9 reciprocates along the upper lifting frame 7, in order to further improve the stability during movement, a second slide groove 18 and a second boss 19 structure that cooperate with each other are designed.

[0042] See attached Figure 5 -Attached Figure 6 An adjusting chamber 23 is provided at the bottom of the upper lifting frame 7, and a symmetrical adjusting motor 24 is installed on the outer wall of the adjusting chamber 23. The output end of the adjusting motor 24 is provided with a threaded rod 25 located in the adjusting chamber 23, and a stamping seat 26 is movably provided in the adjusting chamber 23 and is threadedly connected to the threaded rod 25.

[0043] In this embodiment, under the action of the adjustment motor 24 , the punching seat 26 can move along the adjustment cavity 23 and adjust its position relative to the board to be tested 33 , thereby changing the detection mode.

[0044] See attached Figure 4 and attached Figure 7 A symmetrical unloading tooth plate 22 is installed under the inner wall of the main frame 1, and a linkage gear 36 that engages with the unloading tooth plate 22 is movably installed on both sides of the sliding arm 15. A winding shaft 37 is fixedly provided on the outer wall of the linkage gear 36, and a bandage 38 is wrapped around the winding shaft 37. The end of the bandage 38 is connected to the outer wall of the moving frame 30.

[0045] In this embodiment, after stamping is completed, the lower lifting frame 14 moves downward, and the linkage gear 36 engages with the blanking tooth plate 22. At this time, the linkage gear 36 tightens the bandage 38. Under the action of the bandage 38, the moving frame 30 slides to the sides, at which time the elastic member 35 is stretched and the test plate 33 falls into the storage box 39 below.

[0046] See attached Figure 7 -Attached Figure 8 Symmetrical reset cavities 34 are provided on both sides of the lower lifting frame 14, and an elastic member 35 is provided in the reset cavity 34. The outer side of the elastic member 35 is connected to the inner wall of the moving frame 30; a storage box 39 is also provided at the bottom of the main frame 1 below the lower lifting frame 14.

[0047] In this embodiment, after the test panel 33 is unloaded, an elastic member 35 is provided to allow the movable frame 30 to simultaneously move toward the center, thereby aligning the mounting slots 32 and facilitating subsequent testing. When the lower lifting frame 14 moves upward, the linkage gear 36 disengages the unloading tooth plate 22, causing the bandage 38 to relax and the movable frame 30 to return to its original position under the action of the elastic member 35.

[0048] See attached Figure 7 -Attached Figure 8 A limiting groove 40 is provided on the outer wall of the lower lifting frame 14 , and a slider 41 cooperating with the limiting groove 40 is provided on the inner wall of the moving frame 30 .

[0049] In this embodiment, when the moving frame 30 moves along the lower lifting frame 14 during unloading, in order to further improve the stability during movement, a limiting groove 40 and a sliding block 41 structure that cooperate with each other are designed.

[0050] See attached Figure 2 and attached Figure 6 A control panel 4 is provided on the outer wall of the main frame 1 , and a sensor 29 is provided at the bottom of the first detection part 27 and the second detection part 28 .

[0051] In this embodiment, a control panel 4 is provided to control the movement of the device. A first detection unit 27 includes a set of detection punches, and a second detection unit 28 includes two sets of detection punches. The first detection unit 27 can press down on the center of the test plate 33, simulating an operator's feet simultaneously stepping on the center of the test plate 33. The second detection unit 28 can press down on both sides of the test plate 33, simulating an operator's feet simultaneously stepping on the test plate 33 with their feet spread apart. Sensors 29 are provided to monitor the punching force in real time, thereby testing the strength of test plates 33 made of different materials.

[0052] Working principle of the present invention: When the device is in use, the plate to be tested 33 is first placed on the mounting groove 32. When the upper lifting frame 7 moves downward, the lower lifting frame 14 drives the plate to be tested 33 to move upward. When the first detection part 27 on the punching seat 26 abuts against the plate to be tested 33 and punches it, the second detection part 28 is located in the discharge cavity 31 and does not interfere with the stamping. When the upper lifting frame 7 moves upward, the lower lifting frame 14 drives the plate to be tested 33 to move downward after the inspection is completed. During the movement, the linkage gear 36 will engage with the discharge gear plate 22, and the linkage gear 36 will tighten the bandage 38. Under the action of the bandage 38, the moving frame 30 slides to both sides, and the elastic member 35 is stretched and the plate to be tested 33 falls into the storage box 39 below. When another set of test panels 33 needs to be tested, the lower lifting frame 14 moves upward and the moving frame 30 moves toward the middle and returns to its original position, and then the new test panels 33 are placed in the mounting slots 32 .
