Description

Technical Field

[0001] This utility model relates to the field of tricycle tire testing technology, and in particular to a puncture resistance testing device for electric tricycle tires. Background Technology

[0002] With the increasing popularity of electric tricycles, their driving environment is becoming more diverse and complex, increasing the risk of tires being punctured by sharp objects such as nails and glass shards, which seriously affects driving safety. Therefore, it is necessary to conduct puncture resistance tests on tricycle tires.

[0003] Currently, testing typically involves placing a test pegboard on the ground with multiple nails. A tricycle is then driven over the pegboard, and the tires are inspected afterward. Traditional pegboards usually have fixed protruding nails on their surface, which limits their ability to be arbitrarily combined to simulate different road conditions according to testing requirements.

[0004] Therefore, the traditional nail plates with fixed protrusions on the surface cannot be arbitrarily combined according to testing needs to simulate different road surface scenarios, which has certain limitations. A puncture resistance testing device for electric tricycle tires can be designed to disassemble the traditional fixed nail plate into multiple installation modules with protrusions of different specifications. This allows for rapid configuration according to testing needs, simulating different road surface scenarios, and providing a more comprehensive testing effect. Utility Model Content

The limiting components are located on the upper end of the base, and the protective components are located on the upper end of the side plates.

[0007] Preferably, the protective components can shield and protect the upper part of the base when the overall device is not in use. The positioning slots can position and install the mounting blocks. The cooperation between the positioning slots and the positioning blocks can limit the movement of the mounting blocks installed in the positioning slots. The electromagnets can generate magnetism when energized, thereby magnetically fixing the mounting blocks. The mounting blocks can also be easily disassembled after power is cut off. The protruding nails fixed to the upper ends of the multiple sets of mounting blocks have different shapes and sizes. According to the test requirements, different mounting blocks can be installed into different positioning slots for free configuration to simulate different surface scenarios, resulting in a more comprehensive test effect. The limiting components can limit the tires on the upper part of the base when a tricycle passes by, preventing them from deviating and affecting the test results.

[0008] Preferably, the base has ramps at both ends, with two sets of ramps arranged symmetrically, and an anti-slip pad is fixedly installed at the lower end of the base.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a puncture resistance testing device for electric tricycle tires, comprising a base 1, side plates 2, mounting blocks 3, limiting components, and protective components. The side plates 2 are fixedly mounted on the upper end of the base 1, and two sets of side plates 2 are provided. Multiple sets of positioning grooves 103 are formed on the surface of the base 1, arranged linearly and evenly. An electromagnet 104 is fixedly mounted inside the base 1, with its upper surface communicating with the positioning grooves 103. Multiple sets of mounting blocks 3 are provided, located inside the positioning grooves 103. Multiple sets of positioning blocks 302 are fixedly mounted on the side walls of the mounting blocks 3, engaging with the positioning grooves 103 via the positioning blocks 302. The lower surface of the mounting blocks 3 contacts the electromagnets 104. A protruding nail 301 is fixedly mounted on the upper end of the mounting blocks 3. The limiting components are located on the upper end of the base 1, and the protective components are located on the side plates. The upper end of base 1 is protected by a protective component. When the entire device is not in use, the upper end of base 1 can be shielded and protected. The positioning groove 103 can be used to position and install the mounting iron block 3. The positioning groove 103 and the positioning block 302 can limit the mounting iron block 3 installed in the positioning groove 103. The electromagnet 104 can generate magnetism after being energized, thereby magnetically fixing the mounting iron block 3. It is also convenient to disassemble the mounting iron block 3 after the power is off. The protruding nails 301 fixed on the upper end of multiple sets of mounting iron blocks 3 have different shapes and sizes. According to the test requirements, different mounting iron blocks 3 can be installed into different positioning grooves 103 for free configuration to simulate different surface scenarios and make the test results more comprehensive. The limiting component can limit the tires on the upper end of base 1 when the tricycle passes by to prevent them from deviating and affecting the test results.

[0025] Please see Figure 2 and Figure 3In this embodiment, ramps 101 are provided at both ends of the base 1, and the two sets of ramps 101 are symmetrically arranged. An anti-slip pad 102 is fixedly installed at the lower end of the base 1. The ramps 101 facilitate the tricycle to get on and off the base 1, and the anti-slip pad 102 prevents the base 1 from accidentally sliding during the test, which would affect the test results. The limiting component includes an internal thread block 401, a screw 402, and a limiting plate 403. The internal thread block 401 is fixedly installed on one side of the side plate 2. The screw 402 passes through the internal thread block 401 and the side plate 2 and is threadedly connected to the internal thread block 401. A limiting plate 403 is provided at the inner end of the screw 402, and the limiting plate 403 is rotatably connected to the screw 402. The limiting component includes a through hole 404 and a guide rod 405. Two sets of through holes 404 are provided on the surface of the side plate 2. The guide rod 405 is fixedly installed on one side of the limiting plate 403 and passes through the through hole 404. The guide rod 405 is slidably connected to the through hole 404. By setting the limiting plate 403, the two sides of the tricycle tire can be limited to prevent the tire from deviating when traveling on the upper end of the base 1. By setting the screw 402 to rotate inside the internal thread block 401, the limiting plate 403 can be moved, so that tires of different sizes can be used to limit it. By setting the guide rod 405 and the through hole 404 to cooperate, the movement of the limiting plate 403 can be guided, making its movement more stable.

[0026] Please see Figure 1 and Figure 5In this embodiment, the protective assembly includes a top cover 501, a T-shaped groove 502, and a plug-in plate 503. The top cover 501 is disposed on the upper end of the side plate 2. The side plate 2 has a T-shaped groove 502 inside. Two sets of plug-in plates 503 are fixedly installed on the lower end of the top cover 501. The shape of the plug-in plates 503 corresponds to the T-shaped groove 502. The plug-in plates 503 are located inside the T-shaped groove 502 and are slidably connected to the T-shaped groove 502. By setting the cooperation of the T-shaped groove 502 and the plug-in plates 503, the top cover 501 can be fixed to the upper end of the side plate 2, thereby protecting the upper end of the base 1 when not in use. A fixing bracket 504 is fixedly installed on one end of the side plate 2, and two sets of mounting rods 505 are fixedly installed on one end of the top cover 501. A locking strip 506 is provided around the mounting rods 505, and the locking strip 506 is rotatably connected to the mounting rods 505. Rod 505 is used to install locking bar 506. Under the action of gravity, locking bar 506 will remain hanging down inside the fixing frame 504 when no external force is applied, thus locking the top cover 501 in conjunction with the fixing frame 504. The top cover 501 has a receiving cavity 601 inside. A cover plate 602 is provided at the upper end of the top cover 501. The cover plate 602 is located at the upper end of the receiving cavity 601. Multiple sets of spring hinges 603 are provided at the upper end of the top cover 501. The cover plate 602 and the top cover 501 are rotatably connected by the spring hinges 603. The receiving cavity 601 can store various test debris and mounting iron blocks 3 with different protrusions 301, which is convenient for operators to configure according to test requirements. The cover plate 602 can fold and protect the inside of the receiving cavity 601. The spring hinges 603 can keep the cover plate 602 closed when no external force is applied.

[0027] When working, place the whole device in a suitable test site, rotate the two sets of locking bars 506 along the mounting axis to leave the fixing frame 504, pull the top cover 501 to make the plug plate 503 leave the T-shaped slide 502, and take the top cover 501 out from the top of the side plate 2.

[0028] Open the cover plate 602. According to the actual test requirements, the required mounting iron blocks 3 can be taken out from the receiving cavity 601. The mounting iron blocks 3 are placed into different positioning slots 103 one by one according to the requirements. The mounting iron blocks 3 are positioned by the cooperation of the positioning blocks 302 and the positioning slots 103. Different combinations of protruding nails 301 on the upper end of the mounting iron blocks 3 can simulate different road surface scenarios. After the mounting iron blocks 3 are placed, the electromagnet 104 is energized to fix the mounting iron blocks 3.

[0029] By rotating the screw 402 inside the internal thread block 401, the limiting plate 403 can be moved so that the distance between the two sets of limiting plates 403 is the same as the width of the tire to be tested. This makes it easier for the limiting plate 403 to laterally position the tire passing the upper end of the base 1 and prevent it from deviating during movement, which would affect the test results.

[0030] Then, the ramp 101 is used to facilitate the tricycle to drive onto the base 1. The anti-slip mat 102 can prevent the base 1 from sliding accidentally during the test, which would affect the test results. After the tire passes over the top of the base 1, it will be punctured by the protruding nails 301 on the top of each set of mounting blocks that are fixed in advance, so as to achieve the purpose of the test.

[0031] After use, the electromagnet 104 can be de-energized, the mounting block 3 can be removed from the positioning slot 103 and placed back into the container for storage, and then the top cover 501 can be fixed to the upper end of the side plate 2 by using the cooperation of the plug plate 503 and the T-shaped slide 502. The top cover 501 can protect the upper end of the base 1. After the top cover 501 is fixed, the locking bar 506 can be released. Under the action of gravity, the locking bar 506 rotates along the mounting rod 505 and enters the interior of the fixing frame 504, thereby locking the top cover 501.

[0032] Through the above steps, the positioning slot 103 and the positioning block 302 work together to limit the position of the mounting iron block 3 installed in the positioning slot 103. By setting the electromagnet 104 to generate magnetism after being energized, the mounting iron block 3 is magnetically fixed. After the power is turned off, the mounting iron block 3 can be easily disassembled. The protruding nails 301 fixedly installed on the upper end of multiple sets of mounting iron blocks 3 have different shapes and sizes. According to the test requirements, different mounting iron blocks 3 can be installed into different positioning slots 103 for free configuration to simulate different surface scenarios, and the detection effect is more comprehensive. This solves the problem that the protruding nails 301 on the surface of the traditional detection nail plate are usually fixed and cannot be arbitrarily combined according to the test requirements to simulate different road surface scenarios, which has certain limitations.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
