Description

Technical Field

[0001] This utility model relates to the field of electric vehicle tire testing technology, specifically to an electric vehicle tire testing device that integrates puncture and wear testing. Background Technology

[0002] Electric vehicle tires are one of the most important components of electric vehicles, ensuring that they can travel on the road. These rubber products, designed specifically for electric vehicles, are in direct contact with the ground and bear functions such as load-bearing, cushioning, driving, and braking. In the production of electric vehicle tires, testing equipment is used to test their performance to ensure driving safety and comfort.

[0003] The existing technical solutions have the following drawbacks: when testing electric vehicle tires, the testing device detects the wear resistance of the electric vehicle tires through a friction plate. Since the testing of electric vehicle tires using a friction plate results in a limited testing range, we propose an electric vehicle tire testing device that integrates puncture and wear testing to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a test device for electric vehicle tires that integrates puncture and abrasion testing, in order to solve the problem that the test device proposed in the background art tests the wear resistance of electric vehicle tires through a friction plate, which leads to a limited testing range for electric vehicle tires.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As a preferred technical solution of the present invention, an electric vehicle tire testing device integrating puncture and abrasion testing includes a base plate, on which a friction plate is movably installed at the rear left end; Also includes: The second motor is installed on the front middle side of the base plate, and the output end of the second motor is connected to a movable structure. The movable structure includes an adjusting rod and a mounting plate. The adjusting rod is installed on the output end of the second motor, and the outer side of the adjusting rod is connected to the mounting plate. The electric vehicle tire body is provided on the middle side of the left end of the mounting plate. A connecting block is installed on the front left side of the base plate, and a spike is fixedly installed on the upper side of the connecting block. A connecting structure is installed on the rear left side of the base plate, and the connecting structure includes a limiting block and a fixing rod. The limiting block is installed on the rear left side of the base plate, and a fixing rod is installed on the lower left side of the limiting block.

[0006] Preferably, a first motor is also fixedly installed on the inner middle side of the mounting plate, and a mounting rod is installed at the output end of the first motor.

[0007] Preferably, a telescopic rod is fixedly installed on the upper inner side of the mounting plate, and a movable mounting plate is fixedly installed on the upper side of the telescopic rod, and a spike is connected to the lower left end of the movable mounting plate.

[0008] Preferably, the mounting plate and the base plate are slidably connected, and the mounting plate and the adjusting rod are connected by a threaded drive.

[0009] Preferably, the mounting rod is connected to the electric vehicle tire body by bolts.

[0010] Preferably, the mounting movable plate and the mounting plate are slidably connected, and the vertical cross-sectional shape of the mounting movable plate is an "L" shape.

[0011] Preferably, the limiting block and the friction plate are engaged.

[0012] Preferably, the limiting block and the base plate are slidably connected, and the vertical cross-sectional shape of the limiting block is an "L" shape.

[0013] Preferably, a limit rod is also movably connected to the lower right side of the connecting block.

[0014] Preferably, the connecting block and the base plate are connected by a snap-fit ​​connection, and the connecting block and the limiting rod are connected by a threaded connection.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: the electric vehicle tire testing device for puncture and wear is provided with a movable structure that can move the electric vehicle tire, thereby playing the role of puncture and wear testing on the electric vehicle tire, and is also provided with a connecting structure that can disassemble the friction plate, thereby playing the role of replacing the friction plate. 1. By starting the first motor, the first motor drives the mounting rod to rotate on the left side inside the mounting plate, thereby causing the mounting rod to rotate the electric vehicle tire body, which in turn causes the electric vehicle tire body to rotate on the upper side of the friction plate. This allows for the detection of the wear resistance of the electric vehicle tire body, making it convenient to test the wear resistance of the electric vehicle tire body. 2. By starting the second motor, the second motor drives the adjusting rod to rotate inside the middle of the base plate, causing the mounting plate, which is threadedly connected to the adjusting rod, to slide forward in the middle of the base plate. This causes the mounting plate to drive the mounting rod to slide forward, which in turn causes the electric vehicle tire body to slide forward. This allows the puncture spikes fixed on the upper side of the connecting block to penetrate the interior of the electric vehicle tire body, facilitating puncture testing. Then, by starting the telescopic rod, the telescopic rod drives the mounting moving plate to slide downward inside the mounting plate, causing the mounting moving plate to drive the spike cone downward, which in turn penetrates the interior of the electric vehicle tire body, facilitating puncture testing. 3. By rotating the fixing rod, the fixing rod is threaded to the lower left side of the limiting block, thereby moving the fixing rod to the left and separating it from the left rear side of the base plate. Then, pull the limiting block to the left, causing it to slide to the left rear side of the base plate, thereby separating the limiting block from the left side of the friction plate, and thus separating the friction plate from the left rear side of the base plate, facilitating the disassembly and replacement of the friction plate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-5 The present invention provides the following technical solution: A test device for electric vehicle tires that tests for punctures and abrasion includes: a base plate 1, a friction plate 2, an adjusting rod 3, a mounting plate 4, a first motor 5, a mounting rotating rod 6, an electric vehicle tire body 7, a telescopic rod 8, a mounting moving plate 9, a puncture cone 10, a limiting block 11, a fixing rod 12, a connecting block 13, a puncture cone 14, a limiting rod 15, and a second motor 16. When using it for work, specifically such as Figure 1 and Figure 3 As shown, a friction plate 2 is movably installed on the rear left side of the base plate 1, a controller is set on the front right side of the base plate 1, a mounting plate 4 is movably connected to the rear inside of the base plate 1, a first motor 5 is set in the middle inside the mounting plate 4, a mounting rod 6 is installed at the output end of the first motor 5, and an electric vehicle tire body 7 is set on the left side of the mounting rod 6. The electric vehicle tire body 7 is manually installed on the left side of the mounting rod 6, and then bolts are used to install the electric vehicle tire body 7 on the outer left side of the mounting rod 6. The controller controls the start of the first motor 5, so that the first motor 5 drives the mounting rod 6 to rotate on the left side inside the mounting plate 4. Thus, the mounting rod 6 drives the electric vehicle tire body 7 to rotate, and the electric vehicle tire body 7 rotates on the upper side of the friction plate 2. This allows for the detection of the wear resistance of the electric vehicle tire body 7, making it convenient to test the wear resistance of the electric vehicle tire body 7. Specific examples Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a second motor 16 is fixedly installed on the middle side of the front end of the base plate 1. An adjusting rod 3 is installed at the output end of the second motor 16. The outer side of the adjusting rod 3 is connected to the mounting plate 4. A telescopic rod 8 is fixedly installed on the upper side of the inside of the mounting plate 4. A mounting movable plate 9 is fixedly installed on the upper side of the telescopic rod 8. A spike 10 is fixedly installed on the lower left side of the mounting movable plate 9. A connecting block 13 is installed on the front left side of the base plate 1. A spike 14 is fixedly installed on the middle side of the upper end of the connecting block 13. The controller controls the start of the second motor 16, so that the second motor 16 drives the adjusting rod 3 to rotate in the middle side of the inside of the base plate 1. Thus, under the action of the rotation of the adjusting rod 3, the mounting plate 4, which is threadedly connected to the adjusting rod 3, slides forward in the middle of the base plate 1. While the mounting plate 4 slides forward, the electric vehicle tire body 7 is kept in a rotating state, so that the mounting plate 4 drives the mounting rod 6 to slide forward, and the mounting rod 6 drives the electric vehicle tire body 7 to slide forward. This allows the puncture spike 14 fixedly installed on the upper side of the connecting block 13 to penetrate the interior of the electric vehicle tire body 7, facilitating puncture testing of the electric vehicle tire body 7. Then, the controller controls the activation of the telescopic rod 8, which drives the mounting moving plate 9 to slide downward inside the mounting plate 4. This causes the mounting moving plate 9 to drive the spike 10 to slide downward, allowing the spike 10 to penetrate the interior of the electric vehicle tire body 7, facilitating puncture testing of the electric vehicle tire body 7. Specific examples Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a limiting block 11 is movably connected to the rear left side of the base plate 1. A fixing rod 12 is movably installed on the lower left side of the limiting block 11. Manually turning the fixing rod 12 causes it to be threadedly connected to the lower left side of the limiting block 11. The threaded action between the fixing rod 12 and the limiting block 11 causes the fixing rod 12 to move to the left, thus separating it from the rear left side of the base plate 1. Pulling the limiting block 11 to the left causes it to slide to the left from the rear left side of the base plate 1, thus separating it from the left side of the friction plate 2. This allows the friction plate 2 to separate from the rear left side of the base plate 1, facilitating its disassembly and replacement. Then, by rotating the limiting rod 15, which is movably connected to the lower right side of the connecting block 13, the limiting rod 15 is threaded onto the lower left side of the base plate 1, causing it to move downwards. This separates the limiting rod 15 from the lower right side of the connecting block 13. Pulling the connecting block 13 upwards causes it to slide the spike 14 upwards under tension, thus separating the connecting block 13 from the front left side of the base plate 1, facilitating the disassembly of the spike 14.
