Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0055] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0056] This embodiment provides a wheel testing device, such as Figure 1 As shown, the wheel testing device is used to test the wheel assembly 6, including a support component 1, a sliding component 2, a first test component 3 and a second test component 4; the sliding component 2 is slidably connected to the support component 1, and the sliding component 2 is used to rotatably connect the wheel assembly 6; the first test component 3 and the second test component 4 can be raised and lowered relative to the support component 1, and are distributed in sequence on the sliding path of the sliding component 2.

[0057] The support assembly 1 is arranged on the mounting surface 7, which can be the ground, a test platform, or other plane with supporting strength. The mounting surface 7 should have good load-bearing capacity to bear the overall weight of the wheel assembly 6 assembled on the wheel testing device. The wheel assembly 6 is a light belt type wheel, which mainly includes a wheel body and a light belt arranged on the wheel body. For example, the wheel body can be a rubber wheel, an air cushion wheel, etc.; the light belt can be an LED light belt or a lamp bead, or other luminous materials; the live circuit of the light belt is sealed and arranged in the wheel body and energized, so that the light belt has an imaging display on the wheel body.

[0058] Exemplarily, the support assembly 1 is disposed on the mounting surface 7, and the support assembly 1 has a certain height relative to the mounting surface 7, and the sliding assembly 2 is slidably connected to an end of the support assembly 1 away from the mounting surface 7, so that the sliding assembly 2 is located above the mounting surface 7. When the wheel assembly 6 is connected to the sliding assembly 2, the sliding assembly 2 can drive the wheel assembly 6 to slide relative to the support assembly 1.

[0059] The first test component 3 and the second test component 4 can be arranged on the mounting surface 7, that is, the sliding component 2 is located above the first test component 3 and the second test component 4, and the first test component 3 and the second test component 4 are distributed in sequence on the sliding path of the sliding component 2, that is, the sliding component 2 can be located above one of the first test component 3 and the second test component 4.

[0060] In some embodiments, the first test component 3 and the second test component 4 may also be arranged at intervals on the support component 1 and located below the sliding component 2, so that when the sliding component 2 slides relative to the support component 1, it can be located above one of the first test component 3 and the second test component 4.

[0061] In this embodiment, the first test component 3 and the second test component 4 can both rise or fall relative to the support component 1 to get closer to or away from the sliding component 2, so that the wheel assembly 6 on the sliding component 2 can be tested by the first test component 3 or the second test component 4.

[0062] Among them, the first test component 3 is used to contain liquid. For example, the liquid can be clear water, turbid liquid, etc. The specific type of liquid is adaptively set according to the test target. In actual use: the sliding component 2 slides on the support component 1 to drive the wheel assembly 6 to be located above the first test component 3, and the first test component 3 is moved toward the sliding component 2 so that at least part of the wheel assembly 6 is located in the liquid. According to the test target, the depth of the wheel assembly 6 immersed in the liquid can be adaptively set. For example, when the wheel assembly 6 below the wheel center is completely immersed in the liquid, and a certain rotation speed is set for the wheel assembly 6 to rotate relative to the sliding component 2, the driving scene of the wheel assembly 6 in severe wading conditions can be simulated; or the half part below the wheel center of the wheel assembly 6 is immersed in the liquid, and a certain rotation speed is set for the wheel assembly 6, which can simulate the driving scene of the wheel assembly 6 in general wading conditions.

[0063] Therefore, the sealing performance of the wheel assembly 6 can be tested at different depths of the liquid by presetting the immersion depth of the wheel assembly 6 in the liquid, combining the preset rotation speed of the wheel assembly 6 and the immersion time in the liquid and other test conditions. Specifically, by detecting whether the light strip functions normally, it can be judged whether the sealing performance of the wheel assembly 6 is good. For example, if the light strip functions normally, it means that the wheel body has good protection for the live circuit of the light strip, that is, the sealing performance of the wheel assembly 6 is good. If the light strip functions abnormally, it means that the live circuit of the light strip will fail to function when it encounters water, that is, the sealing performance of the wheel assembly 6 is not good.

[0064] Alternatively, in actual use, the sliding assembly 2 slides on the supporting assembly 1 to drive the wheel assembly 6 to be located above the second test assembly 4, and the second test assembly 4 rotates relative to the sliding assembly 2, and the wheel assembly 6 rotates relative to the sliding assembly 2; the second test assembly 4 moves upward to make the second test assembly 4 abut against the wheel assembly 6, that is, there is a specified contact pressure between the second test assembly 4 and the wheel assembly 6, and they rotate relative to each other. According to the test target, the rising height of the second test assembly 4 can be adaptively adjusted to adjust the contact pressure between the second test assembly 4 and the wheel assembly 6. Different contact pressures make the friction between the wheel assembly 6 and the second test assembly 4 different, so as to simulate the driving scene of the wheel assembly 6 on roads with different flatness.

[0065] Therefore, the contact pressure between the wheel assembly 6 and the second test component 4 can be preset, and the contact pressure can be detected by a pressure sensor or other detection components. In combination with the preset rotation speed and rotation number of the wheel assembly 6, the assembly stability test of the wheel assembly 6 under different pressures can be performed to determine the running state of the wheel assembly 6 under different degrees of potholes. Specifically, by detecting whether the light strip function is normal, or whether the light strip is detached or loose on the wheel body, it can be determined whether the assembly stability of the wheel assembly 6 is good.

[0066] The wheel testing device provided in this embodiment can perform a sealing test or an assembly stability test on the wheel assembly 6 respectively. The first test component 3 and the second test component 4 can be used separately or in combination. That is, the order of using the first test component 3 and the second test component 4 is determined by the adaptability of the scene that needs to be simulated during the test process.

[0067] like Figures 1 to 3 As shown, in this embodiment, the wheel testing device further includes a driving assembly 5, the driving assembly 5 includes at least one first driving member 51 and at least one second driving member 52, and the second testing assembly includes a rotating member 41. Exemplarily, the first driving member 51 and the second driving member 52 are both hydraulic cylinders; the lifting ends of the hydraulic cylinders are respectively connected to the placement box 31 and the rotating member 41, wherein the placement box 31 is filled with a test liquid, and the placement box 31 moves toward the sliding assembly 2 driven by the hydraulic cylinder until at least part of the wheel assembly 6 on the sliding assembly 2 is immersed in the liquid; or, the rotating member 41 moves toward the sliding assembly 2 driven by the hydraulic cylinder until the wheel assembly 6 on the sliding assembly 2 abuts against the rotating member 41 at a specified pressure.

[0068] In this embodiment, a placement box 31 is provided for storing liquid, a rotating member 41 is provided to abut against the wheel assembly 6, and the placement box 31 is provided on the first driving member 51, and the rotating member 41 is provided on the second driving member 52, wherein the material of the placement box 31 may be metal or a composite material, etc., and the setting size of the placement box 31 should be matched with the overall size of the wheel assembly 6 to ensure that the placement box 31 has good load-bearing and waterproof properties, and the wheel assembly 6 can be completely placed in the placement box 31; the rotating member 41 may be a structural member such as a drum, and when the wheel assembly 6 abuts against the drum and rotates relatively, the wheel assembly 6 contacts the outer wall of the drum to simulate the operation of the wheel assembly 6 on an actual road surface.

[0069] The first driving member 51 and the second driving member 52 can be fixed on the mounting surface 7 , so that the placement box 31 and the rotating member 41 are driven by the corresponding driving members to approach or move away from the wheel assembly 6 located above the mounting surface 7 .

[0070] In some embodiments, the first driving member 51 and the second driving member 52 may also be disposed on the supporting assembly 1 to drive the placement box 31 and the rotating member 41 to rise and fall relative to the supporting assembly 1 .

[0071] In actual use, when the wheel assembly 6 is located above one of the first test component 3 or the second test component 4, the hydraulic cylinder converts the hydraulic energy into mechanical energy for lifting, so as to automatically realize the rising or falling of the placement box 31 and the rotating part 41, thereby improving the ease of use of the wheel testing device provided in the embodiment of the present application.

[0072] like Figure 1 and Figure 2 As shown, in order to facilitate the wheel assembly 6 to be placed in the placement box 31 and immersed in the liquid, an opening 311 can be provided on the side of the placement box 31 facing the sliding assembly 2 in an integrated manner, and the diameter of the opening 311 matches the maximum size of the wheel assembly 6. In addition, a first bracket 32 ​​is provided on the first driving member 51, and the other end of the first bracket 32 ​​is connected to the side of the placement box 31 away from the opening 311; illustratively, the first bracket 32 ​​can be a stainless steel or composite material frame, so that the first bracket 32 ​​has good load-bearing capacity, and the structure of the first bracket 32 ​​should match the structure of the placement box 31 to ensure that the placement box 31 is stably set on the first bracket 32. By arranging the first bracket 32 ​​between the placement box 31 and the first driving member 51, the setting height of the placement box 31 relative to the sliding assembly 2 is increased, so that the first driving member 51 does not need to drive the placement box 31 to move a large distance during the rising process of the placement box 31, so as to reduce the driving stroke of the first driving member 51, thereby saving the test time.

[0073] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the rotating member 41 includes a connecting portion 411, a rotating portion 412 and a protruding portion 413. For example, the connecting portion 411 is a bracket connected by a rotating shaft, and one end of the bracket away from the rotating shaft is connected to the second driving member 52, and the rotating portion 412 is arranged on the rotating shaft, wherein the setting direction of the rotating shaft is parallel to the rotating axis of the wheel assembly 6 on the sliding component 2, so as to ensure that the wheel assembly 6 and the rotating portion 412 can rotate relative to each other. By setting the connecting portion 411, it is easy to connect the rotating portion 412 in rotation, and the lifting force of the second driving member 52 is transmitted to the connecting portion 411, so that the rotating portion 412 is driven by the connecting portion 411 to move smoothly toward the wheel assembly 6 until it abuts against the wheel assembly 6.

[0074] In this embodiment, a plurality of protrusions 413 are provided at intervals on the rotating portion 412. When the second driving member 52 drives the connecting portion 411 and the rotating portion 412 to rise toward the wheel assembly 6, the wheel assembly 6 and the rotating portion 412 are in pressure contact, and when the wheel assembly 6 and the rotating portion 412 rotate relative to each other, the wheel assembly 6 will collide with the protrusions 413, thereby simulating the scene of the wheel assembly 6 passing through a pothole on a bumpy road. By providing the protrusions 413, a greater local pressure can be applied to the contact surface of the wheel assembly 6, thereby testing whether the light strip will loosen or fall off under the greater pressure, so as to determine the assembly stability of the wheel assembly 6.

[0075] Exemplarily, the raised portion 413 is trapezoidal, with the large diameter end of the trapezoid facing the rotating portion 412 and the small diameter end facing the wheel assembly 6, so that the raised portion 413 and the rotating portion 412 are reliably connected through a larger contact area. The small diameter end faces the wheel assembly 6. When the raised portion 413 contacts the wheel assembly 6, the raised portion 413 will generate concentrated stress on the surface of the wheel assembly 6, so as to simulate a more severe pothole road surface for the wheel assembly 6.

[0076] In order to make the rotating member 41 smoothly abut against the wheel assembly 6 under the drive of the second driving member 52 and avoid the rotating member 41 from tilting, the number of the second driving members 52 is set to four. For example, the four second driving members 52 are distributed in a quadrilateral, and a second bracket 42 is provided above the second driving member 52. The second bracket 42 is also a rectangular structure, so that the lifting force of the second driving member 52 is evenly applied to the second bracket 42, and then the side of the second bracket 42 facing away from the second driving member 52 is connected to the connecting part 411. The connecting part 411 increases the contact area with the second driving member 52 through the second bracket 42, thereby increasing the connection stability between the rotating member 41 and the second driving member 52.

[0077] In this embodiment, Figure 1 and Figure 5 As shown, the sliding assembly 2 includes a sliding member 21 and a connecting member 22 rotatably arranged on the sliding member 21, and a sliding portion 111 is arranged on the support assembly 1, and the sliding member 21 is slidably connected to the sliding portion 111 to slide relative to the sliding portion 111. Exemplarily, the sliding member 21 is an L-shaped structure, a slider is arranged on one side of the sliding member 21, and the sliding portion 111 on the support assembly 1 is a slide rail slidably connected to the slider, so that the slider drives the sliding member 21 to slide along the slide rail; the connecting member 22 is arranged on the other side of the sliding member 21, and one end of the connecting member 22 is connected to the wheel assembly 6, and the other end is connected to the third driving member 53, and the third driving member 53 is an electric motor. In actual use, the output shaft of the motor is connected to the connecting member 22, and the rotation of the output shaft drives the rotation of the wheel assembly 6.

[0078] The connecting member 22 may include a transmission part 223, a plug-in part 221 and a fixed part 222 which are arranged in sequence. The sliding member 21 is provided with a receiving cavity 211, and a bearing matching the plug-in part 221 is provided in the receiving cavity 211, so that the plug-in part 221 is rotatably connected in the bearing, so that the plug-in part 221 is connected to the sliding member 21. The fixed part 222 at one end of the plug-in part 221 is connected to the wheel assembly 6 through fasteners such as bolts, and the transmission part 223 at the other end is connected to the third driving member 53 through a transmission member 54. Exemplarily, the transmission member 54 is a belt, so that the third driving member 53 and the wheel assembly 6 have good transmission efficiency, and vibration or abnormal sound can be avoided when the third driving member 53 drives the wheel assembly 6 to rotate.

[0079] In this embodiment, Figure 1 As shown, the support assembly 1 includes at least one first support member 11 and at least two second support members 12 arranged on the first support member 11, wherein the first support member 11 and the second support member 12 can be made of high-strength materials such as stainless steel, so that the support assembly 1 has good load-bearing capacity. In actual implementation, a second support member 12 can be arranged at each end of the first support member 11, and the second support member 12 is arranged vertically with the first support member 11, and the end of the second support member 12 away from the first support member 11 is connected to the mounting surface 7. In this way, the sliding part 111 is arranged on the first support member 11, and the first support member 11 is raised by the second support member 12, so that the first test assembly 3 and the second test assembly 4 are arranged below the first support member 11.
