[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 , Figure 2As shown, a scooter durability testing device includes a base 1, a fixing frame 2 fixedly connected to the upper surface of the base 1, a support component 3 fixedly connected to the upper surface of the base 1, the outer wall of the support component 3 being movably sleeved with the inner wall of the fixing frame 2, a pressure testing component 5 fixedly connected to the center portion of the top of the inner wall of the fixing frame 2, two symmetrically positioned frame fixing components 4 fixedly connected to the front and rear portions of the top of the inner wall of the fixing frame 2, with the two frame fixing components 4 located on the front and rear sides of the pressure testing component 5 respectively, and a handlebar fixing component 6 fixedly connected to the left portion of the top of the inner wall of the fixing frame 2. Component 6 is located to the left of vehicle body fixing component 4 and pressure testing component 5. Support component 3 includes wheel testing component 1 31. The lower surface of wheel testing component 1 31 is fixedly connected to the left part of the upper surface of base 1. Auxiliary connecting component 32 is fixedly connected to the right side of wheel testing component 1 31. Wheel testing component 2 33 is fixedly connected to the right side of auxiliary connecting component 32 and wheel testing component 2 33 is located on the upper surface of base 1. Adjustment component 34 is fixedly installed on the right side of wheel testing component 2 33. The lower surface of the right part of adjustment component 34 is fixedly connected to the upper surface of base 1.

[0031] First, by adjusting component 34, the position of wheel test component 2 33 can be adjusted according to the size of the scooter. Then, the scooter is placed on the upper surface of wheel test component 1 31 and wheel test component 2 33. At this time, the scooter body is clamped and fixed by the body fixing component 4. Then, the handlebar fixing component 6 clamps and fixes the scooter's front end. Then, by the action of wheel test component 2 33 and wheel test component 1 31, the scooter's wheels can undergo rotational durability testing. Next, by the action of the upper hydraulic rod of pressure test component 5, the lower pressure block of pressure test component 5 can move downward to the upper surface of the scooter body, thereby conducting pressure durability testing on the scooter.

[0032] like Figure 3 As shown, the vehicle body fixing assembly 4 includes a second hydraulic rod 41. The upper surface of the second hydraulic rod 41 is fixedly connected to the top of the inner wall of the fixing frame 2. The output end of the second hydraulic rod 41 is fixedly connected to a lifting frame 42. The outer wall of the lifting frame 42 is movably sleeved with the inner wall of the fixing frame 2. The inner cavities of the left and right parts of the lifting frame 42 are slidably connected to limit guide rods 43. The upper surfaces of the two limit guide rods 43 are fixedly connected to the top of the inner wall of the fixing frame 2 respectively.

[0033] The lifting frame 42 can adjust the height of the clamping plate 45 under the action of the two limit guide rods 43 through the action of the hydraulic rod 41.

[0034] A hydraulic rod 44 is fixedly connected to the middle of the lifting frame 42 near the pressure test assembly 5. A clamping plate 45 is fixedly connected to the output end of the hydraulic rod 44 and the clamping plate 45 is located below the pressure test assembly 5. The outer wall of a portion of the guide rod of the clamping plate 45 away from the pressure test assembly 5 is slidably connected to the inner cavity of the middle of the lifting frame 42.

[0035] The hydraulic rod 44 allows the clamping plate 45 to approach one side of the scooter body, thereby clamping and fixing the scooter body under the action of the two clamping plates 45, thus ensuring the stability of the scooter during the test.

[0036] like Figure 4 As shown, the handlebar fixing assembly 6 includes two electric push rods 61. The outer walls of the opposite portions of the two electric push rods 61 are fixedly connected to the inner cavity of the left portion of the fixing frame 2. The output ends of the two electric push rods 61 are fixedly connected to movable slides 62. The outer walls of the upper portions of the two movable slides 62 are slidably connected to guide rails 63, and the guide rails 63 are located above the two electric push rods 61. The outer wall of the guide rails 63 is fixedly connected to the inner cavity of the left portion of the fixing frame 2.

[0037] The electric push rod 61 enables the two movable carriages 62 to move towards each other under the action of the guide rail 63, thereby allowing the two arc-shaped clamps 66 to move towards each other to the front and rear sides of the vehicle platform, thus clamping and fixing the handlebars.

[0038] Electric push rods 64 are fixedly connected to the inner cavities of the lower parts of the two movable slides 62. The output ends of the two electric push rods 64 are fixedly connected to fixed plates 65, and the two fixed plates 65 are located below the two movable slides 62. The outer walls of the guide rods of the opposite parts of the two fixed plates 65 are slidably connected to the inner cavities of the lower parts of the two movable slides 62.

[0039] The height of the fixed plate 65 and the arc-shaped clamp 66 can be adjusted by the electric push rod 64, so that it can be adjusted according to the size of the scooter.

[0040] like Figure 5 As shown, arc-shaped clamps 66 are fixedly connected to the opposite surfaces of the two fixed plates 65, and arc-shaped rubber protective pads 67 are fixedly connected to the inner walls of the two arc-shaped clamps 66.

[0041] The curved rubber protective pad 67 ensures that the curved clamp 66 can hold and fix the scooter handlebars stably without damaging its outer wall, thus ensuring product quality.

[0042] like Figure 6As shown, the adjustment assembly 34 includes a limiting slide 343. The lower surface of the limiting slide 343 is fixedly connected to the upper surface of the right part of the base 1. A hydraulic rod 341 is fixedly connected to the middle of the left side of the limiting slide 343 and the hydraulic rod 341 is located below the wheel test assembly 33. A connecting block 342 is fixedly connected to the output end of the hydraulic rod 341. The outer wall of the connecting block 342 is movably sleeved with the inner wall of the right part of the base 1. The upper surface of the connecting block 342 is fixedly connected to the left part of the lower surface of the wheel test assembly 33. The outer walls of the four guide rods on the left side of the limiting slide 343 are slidably connected to the inner cavity of the wheel test assembly 33.

[0043] The hydraulic rod 341 causes the connecting block 342 to move to the left, which in turn causes the wheel test assembly 33 to move to the left under the action of the limiting slide 343, thereby adjusting the distance between the fixed shell 311 and the wheel test assembly 33.

[0044] like Figure 7 , Figure 8 As shown, the wheel test assembly 31 includes a fixed shell 311. The lower surface of the fixed shell 311 is fixedly connected to the upper surface of the base 1. The right side of the fixed shell 311 is fixedly connected to the left side of the four guide rods on the left side of the limiting slide 343. A motor 312 is fixedly connected to the inner cavity of the left side of the fixed shell 311. A threaded rod 313 is fixedly connected to the output end of the motor 312. The outer walls of the left and right sides of the threaded rod 313 are rotatably connected to the inner cavity of the fixed shell 311. Two movable support frames 314 are threadedly connected to the outer wall of the middle part of the threaded rod 313. Two guide rails 315 are slidably connected to the lower surfaces of the front and rear parts of the two movable support frames 314, and the two guide rails 315 are located on the front and rear sides of the threaded rod 313, respectively. Rollers 316 are rotatably connected to the inner walls of the upper parts of the two movable support frames 314, and the two rollers 316 are located above the fixed shell 311.

[0045] The motor 312 causes the threaded rod 313 to rotate, which allows the two movable support frames 314 to move towards each other under the action of the guide rail 315. This facilitates adjustment according to the size of the scooter wheels and makes it easier to perform rolling tests on the scooter wheels.

[0046] like Figure 9 As shown, the auxiliary connection assembly 32 includes a square plate 321. The left side of the square plate 321 is fixedly connected to the right side of the threaded rod 313. A limit sleeve 322 is inserted into the outer wall of the square plate 321. The right side of the limit sleeve 322 is fixedly connected to the left side of the threaded rod in the center of the wheel test assembly 33.

[0047] By utilizing the square plate 321 and the limiting sleeve 322, the motor 312 can adjust the spacing between the two rollers 316 and the two rollers on the upper part of the wheel test assembly 33 when it rotates, thereby saving energy consumption and improving efficiency.

[0048] The working principle of this utility model is as follows: First, the connecting block 342 moves to the left through the action of hydraulic rod 341, thereby causing the wheel testing assembly 33 to move to the left under the action of the limiting slide 343. This allows adjustment of the distance between the fixed shell 311 and the wheel testing assembly 33. Then, the threaded rod 313 rotates through the action of motor 312, causing the two movable support frames 314 to move towards each other under the action of guide rail 315. This facilitates adjustment according to the size of the scooter wheel. Next, the scooter is placed on the upper surface of the wheel testing assembly 31 and the wheel testing assembly 33. At this time, the lifting frame 42 adjusts the height of the clamping plate 45 under the action of the two limiting guide rods 43 through the action of hydraulic rod 41. Then, the clamping plate 45 moves closer to the scooter through the action of hydraulic rod 44. The handlebars are clamped and fixed to one side of the scooter body under the action of two clamping plates 45, thus ensuring the stability of the scooter during the test. Then, the height of the fixing plate 65 and the arc-shaped clamping plate 66 can be adjusted by the action of the electric push rod 64, so as to make it easy to adjust and use according to the size of the scooter. Then, the two movable slides 62 can move towards each other under the action of the guide rail 63 by the action of the electric push rod 61, so that the two arc-shaped clamping plates 66 can move towards each other to the front and rear sides of the board, thereby clamping and fixing the handlebars. Then, the wheels of the scooter can be subjected to rotational durability test by the action of the roller 316. Finally, the lower pressure block of the pressure test component 5 can be moved down to the upper surface of the scooter body by the action of the upper hydraulic rod of the pressure test component 5, thereby conducting a pressure durability test on the scooter.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
