Description

Technical Field

[0001] This application relates to the field of skateboard control testing technology, and in particular to a fatigue testing device for the throttle roller of a skateboard remote control. Background Technology

[0002] In recent years, with the popularization of personal electric vehicles such as electric skateboards and electric surfboards, the accompanying skateboard remote control has become a key control component. The skateboard remote control controls actions such as braking and acceleration through the throttle wheel.

[0003] Currently, fatigue testing of throttle rollers in remote control devices almost exclusively focuses on testing the roller encoder, while there is a lack of effective testing methods and equipment for the rebound spring of the throttle roller.

[0004] Therefore, there is a need for a testing device capable of performing fatigue tests on the return spring of the throttle roller in a skateboard remote control. Utility Model Content

[0005] Therefore, it is necessary to provide a fatigue testing device for the throttle roller of a skateboard remote control, and its specific technical solution is as follows.

[0006] A fatigue testing device for the throttle roller of a skateboard remote control includes: Work surface; A mounting bracket is used to secure the remote control for the skateboard; the mounting bracket is installed on the workbench surface. A roller drive component is rotatably mounted on a worktable surface; the roller drive component is fan-shaped, and the roller drive component includes a fan-shaped profile surface, which abuts against the throttle roller; A rotary drive component, connected to a roller drive component, is used to drive the roller drive component to rotate.

[0007] Furthermore, the roller drive component includes a body and an elastic pad layer, the elastic pad layer being in contact with the body and abutting against the throttle roller.

[0008] Furthermore, the two sides of the main body are respectively provided with barbed grooves, and the two ends of the elastic pad are respectively engaged in the barbed grooves.

[0009] Furthermore, the body includes a bonding surface that adheres to the elastic pad layer. The outline of the bonding surface is fan-shaped, and both ends of the bonding surface are respectively provided with inclined surfaces, so that a gap is formed between the inclined surfaces and the elastic pad layer.

[0010] Furthermore, the bonding surface is provided with a plurality of teeth arranged along the circumference of the bonding surface.

[0011] Furthermore, the central angle of the fan-shaped profile is less than or equal to the maximum rotation angle of the throttle roller.

[0012] Furthermore, the fixing frame includes a base and a limiting bracket. The base is provided with a placement slot for placing the skateboard remote control. The limiting bracket is detachably connected to the base and presses the skateboard remote control into the placement slot.

[0013] Furthermore, the end of the roller drive component with the throttle roller mounted extends outward from the placement groove.

[0014] Furthermore, the fixing frame is provided with a limiting hole and an arc-shaped hole; a first connecting member passes through the limiting hole and connects to the worktable surface, and a second connecting member passes through the arc-shaped hole and connects to the worktable surface.

[0015] Furthermore, the roller drive component is detachably connected to the rotary drive component; the specifications of the roller drive component are changed according to the specifications of the throttle roller.

[0016] Beneficial effects: The fatigue testing device for the throttle roller of a skateboard remote control provided by this utility model drives the roller drive component to rotate through the rotation drive component. Since the fan-shaped profile surface of the roller drive component abuts against the throttle roller, it drives the throttle roller to rotate. Since the roller drive component is fan-shaped, after rotating a certain angle, the throttle roller will quickly disengage from the fan-shaped profile surface. The throttle roller rebounds under the action of the rebound spring, thereby conducting fatigue testing on the rebound spring and realizing the centering test of the throttle roller.

[0026] Example Reference Figure 1-4 As shown, this embodiment provides a fatigue testing device for the throttle roller of a skateboard remote control, including a worktable 1, a fixed frame 2, a roller drive component 3, and a rotation drive component.

[0027] The fixing bracket 2 is mounted on the workbench 1 and is used to fix the remote control 4. The roller drive component 3 is rotatably mounted on the workbench 1; the roller drive component 3 is fan-shaped, therefore, the roller drive component 3 includes a fan-shaped profile surface 31, which is used to abut against the throttle roller 41, so that when the roller drive component 3 rotates, it drives the throttle roller 41 to rotate, and after rotating a certain angle, the throttle roller 41 smoothly separates from the roller drive component 3, thereby conducting fatigue testing of the rebound spring. The rotary drive component (not shown in the figure) is connected to the roller drive component 3 and is used to drive the roller drive component 3 to rotate.

[0028] In this embodiment, the rotary drive can be a motor, which can be installed below the worktable 1.

[0029] The fatigue testing device for the throttle roller of a skateboard remote control provided in this embodiment drives the roller drive component 3 to rotate through a rotary drive component. Since the fan-shaped profile surface 31 of the roller drive component 3 abuts against the throttle roller 41, it drives the throttle roller 41 to rotate. Since the roller drive component 3 is fan-shaped, after rotating a certain angle, the throttle roller 41 will quickly disengage from the fan-shaped profile surface 31. The throttle roller 41 rebounds under the action of the rebound spring, thereby performing a fatigue test on the rebound spring and realizing the centering test of the throttle roller 41.

[0030] Specifically, refer to Figure 3 As shown, the roller drive component 3 includes a body 32 and an elastic pad 33. The elastic pad 33 is attached to the body 32 and abuts against the throttle roller 41. By compressing the elastic pad 33 with the throttle roller 41, the friction between the roller drive component 3 and the throttle roller 41 is increased, ensuring that the roller drive component 3 drives the throttle roller 41 to rotate when it rotates.

[0031] Specifically, the main body 32 has barbed grooves 34 on both sides, and the two ends of the elastic pad 33 are respectively engaged in the barbed grooves 34. This facilitates the installation of the elastic pad 33 onto the roller drive component 3. It should be noted that in this embodiment, the elastic pad 33 is made of rubber material; in other embodiments, the elastic pad 33 may also be made of other elastic materials.

[0032] Specifically, refer to Figure 4 As shown, the body 32 includes a mating surface that adheres to the elastic pad 33. The mating surface has a fan-shaped outline, and each end of the mating surface is provided with an inclined surface 35, forming a gap between the inclined surface 35 and the elastic pad 33. By providing the inclined surface 35, when the throttle roller 41 rotates relative to the roller drive member 3 to the position of the inclined surface 35, it can smoothly disengage from the roller drive member 3, avoiding any impact on the rebound spring and improving the accuracy of detection.

[0033] Specifically, the mating surface is provided with a plurality of teeth 36 arranged along the circumference of the mating surface. When the roller drive 3 and the throttle roller 41 are pressed together, the teeth 36 further compress and deform the elastic pad layer 33, so that the roller drive 3 can better drive the throttle roller 41 to rotate.

[0034] It should be noted that, in order to improve the adhesion between the elastic pad 33 and the bonding surface of the body 32, the elastic pad 33 can be bonded to the bonding surface by adhesive.

[0035] Specifically, the central angle of the sector-shaped profile surface 31 is less than or equal to the maximum rotation angle of the throttle roller 41. In this embodiment, the central angle of the sector-shaped profile surface 31 can be set to be equal to the maximum rotation angle of the throttle roller 41. For example, if the maximum rotation angle of the throttle roller 41 in the acceleration direction is 34° and the maximum rotation angle in the braking direction is -34°, the central angle of the sector-shaped profile surface 31 can be set to 68°.

[0036] Specifically, refer to Figure 1 and Figure 2As shown, the mounting bracket 2 includes a base 21 and a limiting bracket 22. The base 21 has a placement slot 23 for placing the skateboard remote control 4. The limiting bracket 22 is detachably connected to the base 21 and presses the skateboard remote control 4 into the placement slot 23. The base 21 and the limiting bracket 22 control the skateboard remote control 4, preventing it from shaking during testing and affecting the test results. It should be noted that the outline of the placement slot 23 and the shape of the limiting bracket 22 can be designed according to the external contour of the skateboard remote control 4, thereby minimizing the shaking of the skateboard remote control 4 during testing.

[0037] Specifically, one end of the roller drive component 3 on which the throttle roller 41 is mounted extends outward from the placement groove 23. This facilitates the abutment of the throttle roller 41 against the fan-shaped profile surface 31 of the roller drive component 3.

[0038] Specifically, the fixing frame 2 is provided with a limiting hole 24 and an arc-shaped hole 25; a first connecting member (not shown in the figure) passes through the limiting hole 24 and connects to the worktable surface 1, and a second connecting member (not shown in the figure) passes through the arc-shaped hole 25 and connects to the worktable surface 1. The angle of the fixing frame 2 can be adjusted by means of the arc-shaped hole 25 to accommodate throttle rollers 41 of different specifications and sizes. The first and second connecting members can be made of screws.

[0039] Specifically, the roller drive component 3 is detachably connected to the rotary drive component; the specifications of the roller drive component 3 are changed according to the specifications of the throttle roller 41. This allows for testing of throttle rollers 41 with different specifications, improving applicability.

[0040] Testing process: Throttle direction rebound spring test: Rotate the drive component clockwise, causing the roller drive component 3 to rotate clockwise, thereby driving the throttle roller 41 to rotate counterclockwise. When the throttle roller 41 moves relative to the roller drive component 3 to its inclined surface 35 position, it contacts the elastic pad 33 and smoothly disengages. The throttle roller 41 returns to the center by relying on the rebound spring, thereby conducting a fatigue test on the rebound spring in the throttle direction.

[0041] Braking direction rebound spring test: The rotation drive is reversed, causing the roller drive 3 to rotate counterclockwise, thereby driving the throttle roller 41 to rotate clockwise. When the throttle roller 41 moves relative to the roller drive 3 to its inclined surface 35 position, it contacts the elastic pad 33 and then smoothly disengages. The throttle roller 41 returns to the center by relying on the rebound spring, thereby conducting a fatigue test on the rebound spring in the braking direction.

[0042] Reciprocating test: The rotary drive component rotates in both forward and reverse directions, thereby driving the throttle roller 41 to rotate clockwise and counterclockwise to achieve the reciprocating test.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
