Description

Technical Field

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

[0002] Electric motorcycles are two-wheeled vehicles powered by electric motors and fueled by batteries. Compared to traditional gasoline-powered motorcycles, they offer significant advantages such as zero emissions, low noise, and low energy consumption, aligning with the global concepts of green environmental protection and sustainable development. Therefore, they have experienced rapid popularization and development in the short-distance travel sector. With continuous advancements in new energy technologies, the performance of electric motorcycles continues to improve, their range gradually increases, and their speed and load-bearing capacity are constantly optimized, making them an indispensable part of urban and rural transportation. In the overall performance of electric motorcycles, tire quality directly affects the vehicle's driving safety, stability, comfort, and energy efficiency. Among these, tire roundness and runout are key indicators of tire quality. Tire roundness refers to the degree of deviation of the tire's outer circumference from an ideal circle. Poor roundness causes periodic radial runout during rolling, resulting in bumps and vibrations during driving. This not only affects ride comfort but also accelerates uneven tire wear, shortens tire lifespan, and may even lead to tire blowouts due to uneven stress. Tire runout refers to the axial wobble of the tire's end face or radial direction during rotation. This wobble causes uneven contact area and pressure distribution between the tire and the ground, resulting in vehicle deviation, reduced handling performance, and increased driving difficulty, especially at high speeds, which can easily lead to traffic accidents.

[0003] Chinese utility model patent CN209295907U discloses a device for detecting runout value of tire roundness, including a frame, a cylinder, an upper synchronous pulley, an upper wheel, a synchronous square steel, a lower wheel, a lower synchronous pulley, an inflation duct, a motor, a measuring mechanism, and a control box. The cylinder is vertically mounted above the frame, with the bottom end of its cylinder rod connected to the upper wheel. The upper synchronous pulley is connected to the upper wheel. The lower wheel is mounted on the frame directly below the upper wheel, with the lower synchronous pulley connected to the lower wheel. Both ends of the synchronous square steel are connected to the upper and lower synchronous pulleys, respectively. The motor is located at the bottom of the frame, with its output end connected to the bottom end of the synchronous square steel.

[0004] The above-mentioned device addresses some of the shortcomings of existing technologies, but some deficiencies still exist: For example, the above-mentioned device can only perform roundness detection, but cannot perform swing detection at the same time, and the overall cost is relatively high, making it unsuitable for promotion and use in small repair stations.

[0005] Therefore, we propose an electric motorcycle testing device. Utility Model Content

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Please refer to Figures 1 to 5 As shown, an embodiment of this utility model provides an electric motorcycle testing device, including a support base 1, a vertical plate 2 fixedly installed on the top of one side of the support base 1, a movable seat 3 slidably installed on the top of the other side of the support base 1, a clamping mechanism 7 for clamping the electric motorcycle tire to be tested is provided between the vertical plate 2 and the movable seat 3, a driving component 4 for driving the movable seat 3 to move is provided on the support base 1, a roundness detection component 6 for roundness detection of the electric motorcycle tire to be tested is provided on one side of the vertical plate 2, and a swing detection component 5 for swing detection of the electric motorcycle tire to be tested is provided at the lower end of the movable seat 3.

[0022] In this embodiment, the swing detection component 5 includes a moving rod 501, a guide sleeve 502, and a mounting plate 505. The guide sleeve 502 passes through the moving base 3 and is fixedly connected to the moving base 3. One end of the moving rod 501 is slidably inserted into the guide sleeve 502. The mounting plate 505 is fixed on the side of the moving base 3 away from the moving rod 501. A first connecting rod 5011 is fixedly connected to the end of the moving rod 501 near the mounting plate 505. The end of the first connecting rod 5011 away from the moving rod 501 slides through the mounting plate 505. 05. A first clamping block 506 is fixedly connected to one end of the mounting plate 505 away from the moving rod 501. The first clamping block 506 holds the first dial indicator 507 by a first handle bolt. One end of the first connecting rod 5011 away from the moving rod 501 can abut against the detection end of the first dial indicator 507. A first spring 508 is sleeved on the first connecting rod 5011. One end of the first spring 508 abuts against one side of the moving rod 501, and the other end of the first spring 508 abuts against one side of the mounting plate 505.

[0023] By adopting the above technical solution, the guide sleeve 502 provides sliding guidance for the moving rod 501. The first spring 508 is in a compressed state, and its elastic force pushes the moving rod 501 to move towards the electric motorcycle tire, so that the end of the moving rod 501 is in contact with the surface of the electric motorcycle tire. When the electric motorcycle tire rotates and swings, the undulation of the electric motorcycle tire surface will push the moving rod 501 to slide along the guide sleeve 502, thereby driving the first connecting rod 5011 to move. The movement of the first connecting rod 5011 will be transmitted to the detection end of the first dial indicator 507, and finally display the swing value of the electric motorcycle tire.

[0024] In this embodiment, a roller 503 is rotatably mounted on the end of the movable rod 501 away from the first connecting rod 5011.

[0025] By adopting the above technical solution, the roller 503 is rotatably installed at the end of the moving rod 501. When the electric motorcycle tire rotates, the roller 503 contacts the surface of the electric motorcycle tire and rolls with the electric motorcycle tire, converting the sliding friction between the moving rod 501 and the electric motorcycle tire into rolling friction, reducing the wear on the surface of the electric motorcycle tire, and making the sliding of the moving rod 501 smoother, thereby improving the accuracy of the swing detection.

[0026] In this embodiment, a guide groove 5012 is provided on the outer wall of the moving rod 501, and a limit bolt 504 is threadedly installed on the guide sleeve 502. The screw of the limit bolt 504 extends into the guide groove 5012, and the screw of the limit bolt 504 is slidably connected to the guide groove 5012.

[0027] By adopting the above technical solution, the screw of the limiting bolt 504 extends into the guide groove 5012 of the moving rod 501, which can limit the rotation of the moving rod 501 when it slides along the guide sleeve 502, ensuring that the moving rod 501 only moves axially; at the same time, the sliding connection between the limiting bolt 504 and the guide groove 5012 does not affect the normal sliding of the moving rod 501, ensuring the stable transmission of force during the swing detection process.

[0028] In this embodiment, the driving component 4 includes a lead screw 401, which is rotatably mounted on the support base 1 via a third bearing 402. A limiting sliding hole 101 is provided on the top of the support base 1, and an internal threaded sleeve 301 is fixedly connected to the bottom of the movable base 3. The internal threaded sleeve 301 is slidably mounted in the limiting sliding hole 101 and is threadedly rotated on the lead screw 401.

[0029] By adopting the above technical solution, the lead screw 401 is mounted on the support base 1 through the third bearing 402 and can rotate around its own axis; the internal threaded sleeve 301 is fixed to the bottom of the movable base 3 and is threadedly connected to the lead screw 401. At the same time, the internal threaded sleeve 301 slides in the limiting sliding hole 101 and is restricted from rotating; when the lead screw 401 rotates, the internal threaded sleeve 301 moves along the axial direction of the lead screw 401 under the action of the thread, thereby driving the movable base 3 to slide on the support base 1, so as to realize the clamping mechanism 7 clamping or releasing the electric motorcycle tire.

[0030] In this embodiment, a handwheel 403 is fixedly connected to one end of the lead screw 401.

[0031] By adopting the above technical solution, the handwheel 403 is fixed to one end of the lead screw 401. The lead screw 401 can be rotated by manually turning the handwheel 403, without the need for an additional power device, making the operation simple.

[0032] In this embodiment, both ends of the movable base 3 are fixedly connected to a connecting plate 302, the bottom of the connecting plate 302 is fixedly connected to a slider 405, the top of the support base 1 is fixedly connected to a guide block 404, and the slider 405 is slidably mounted on the guide block 404.

[0033] By adopting the above technical solution, the movable seat 3 is connected to the slider 405 through the connecting plate 302, and the slider 405 slides on the guide block 404 of the support seat 1. When the driving component 4 drives the movable seat 3 to move, the cooperation between the slider 405 and the guide block 404 provides additional guiding support for the movable seat 3, preventing the movable seat 3 from tilting or shaking during the movement, and ensuring that the movable seat 3 moves smoothly along a straight line.

[0034] In this embodiment, the roundness detection component 6 includes a movable block 601 and a guide rod 605. A side plate 201 is fixedly connected to one side of the upright plate 2. One end of the guide rod 605 is fixed to the upright plate 2 via a fixing seat 606, and the other end of the guide rod 605 is fixed to the side plate 201. The movable block 601 is slidably sleeved on the guide rod 605. A fixing plate 602 is fixedly connected to one side of the movable block 601. Tensioning wheels 603 are rotatably mounted on the fixing plate 602. Three tensioning wheels 603 are provided, and the three tensioning wheels 603 are connected by a detection belt 604. The guide rod 605 has a section at one end near the side plate 201. An adjusting nut 608 is threaded onto one end of the guide rod 605 near the side plate 201. A second spring 607 is sleeved on the guide rod 605. One end of the second spring 607 abuts against one side of the moving block 601. A second connecting rod 6011 is fixedly connected to one end of the moving block 601. The end of the second connecting rod 6011 away from the moving block 601 slides through the side plate 201. A second clamping block 609 is fixedly connected to one side of the side plate 201. A second dial indicator 610 is fixedly installed on the second clamping block 609 by a second handle bolt. One end of the second connecting rod 6011 can abut against the detection end of the second dial indicator 610.

[0035] By adopting the above technical solution, the guide rod 605 is fixed by the fixed seat 606 and the side plate 201, providing sliding guidance for the moving block 601; the second spring 607 is compressed by the adjusting nut 608 and the moving block 601, and its elastic force pushes the moving block 601 to move towards the electric motorcycle tire, so that the detection belt 604 is in close contact with the surface of the electric motorcycle tire; when the electric motorcycle tire rotates, if there is a roundness deviation, the undulation of the electric motorcycle tire surface will push the detection belt 604 and the tension wheel 603, causing the moving block 601 to slide along the guide rod 605; the movement of the moving block 601 is transmitted to the detection end of the second dial indicator 610 through the second connecting rod 6011, and the second dial indicator 610 displays the roundness value of the electric motorcycle tire; the adjusting nut 608 can adjust the compression of the second spring 607, controlling the contact force between the detection belt 604 and the electric motorcycle tire.

[0036] In this embodiment, the clamping mechanism 7 includes a first rotating shaft 701 and a second rotating shaft 703. The first rotating shaft 701 is rotatably mounted on the upper end of the movable seat 3 via a first bearing seat, and the second rotating shaft 703 is rotatably mounted on the upper end of the upright plate 2 via a second bearing seat. A first clamping block 702 is fixedly connected to one end of the first rotating shaft 701, and a second clamping block 704 is fixedly connected to one end of the second rotating shaft 703.

[0037] By adopting the above technical solution, the first rotating shaft 701 is mounted on the movable seat 3 through the first bearing seat, and the second rotating shaft 703 is mounted on the upright plate 2 through the second bearing seat. Both can rotate freely. When the driving component 4 drives the movable seat 3 to move, the first clamping block 702 moves closer to the second clamping block 704 along with the first rotating shaft 701, and cooperates with the second clamping block 704 to clamp the center holes on both sides of the electric motorcycle tire.

[0038] In this embodiment, both the first clamping block 702 and the second clamping block 704 are arranged in a frustum shape.

[0039] By adopting the above technical solution, the frustum-shaped structure of the first clamping block 702 and the second clamping block 704 is adapted to the center holes of electric motorcycle tires with different inner diameters. When clamping electric motorcycle tires of different sizes, the inclined side of the frustum can fit against the inner wall of the center hole of the electric motorcycle tire, increasing the contact area. At the same time, the frustum-shaped structure can play a centering role for the electric motorcycle tire, ensuring that the electric motorcycle tire rotates around its own axis during the inspection process, improving the accuracy of swing and roundness detection, and enhancing the versatility of the clamping mechanism 7 for electric motorcycle tires of different specifications.

[0040] Specific testing process of electric motorcycle testing equipment I. Preparations before testing Equipment inspection: Confirm that the support base 1 is placed stably, all components are firmly connected, the pointers of the first dial indicator 507 and the second dial indicator 610 are zero, the first spring 508 and the second spring 607 are not stuck or deformed, and the lead screw 401 rotates smoothly.

[0041] Tire installation preparation: Remove the tires of the electric motorcycle to be tested and clean the mud, stones and other debris from the tire surface to avoid affecting the testing accuracy.

[0042] II. Tire clamping operation Adjust the position of the movable seat: Turn the handwheel 403 clockwise to drive the lead screw 401 to rotate through the third bearing 402. The internal threaded sleeve 301 moves away from the vertical plate 2 along the limiting slide hole 101, thereby causing the movable seat 3 to slide on the guide block 404 through the slider 405, increasing the distance between the vertical plate 2 and the movable seat 3, which is convenient for placing the tire.

[0043] Tire placement: Place the tire between the first clamping block 702 and the second clamping block 704, ensuring that the center hole of the tire is aligned with the frustum-shaped ends of the two clamping blocks.

[0044] Clamping the tire: Turn the handwheel 403 counterclockwise to drive the moving seat 3 to approach the upright plate 2, so that the first clamping block 702 and the second clamping block 704 are inserted into the center hole of the tire and fit tightly against the inner wall frustum-shaped structure for automatic centering until the tire is stably clamped. At this time, the first rotating shaft 701 and the second rotating shaft 703 can rotate freely with the tire through the bearing seat.

[0045] III. Testing Procedures Contacting the tire surface: In the runout detection assembly 5, the elastic force of the first spring 508 pushes the moving rod 501 to slide along the guide sleeve 502, so that the roller 503 at the end of the moving rod 501 is in close contact with the tire sidewall. Then, the position of the detection end of the first dial indicator 507 is adjusted by the first handle bolt so that the detection end of the first dial indicator 507 contacts the end of the first connecting rod 5011.

[0046] Fitting the outer circle of the tire: In the roundness detection assembly 6, the elastic force of the second spring 607 pushes the moving block 601 to slide along the guide rod 605, so that the three tensioning wheels 603 on the fixed plate 602 fit against the outer circle surface of the tire through the detection belt 604. The spring force can be adjusted by adjusting the nut 608 so that the detection belt 604 fits against the tire. Then, the position of the detection end of the second dial indicator 610 is adjusted by the second handle bolt so that the detection end of the second dial indicator 610 contacts the end of the second connecting rod 6011.

[0047] Rotate the tire and take a reading: Slowly rotate the tire one revolution. The sway deviation on the side of the tire will push the roller 503 to drive the moving rod 501 to slide axially. Then, it will be transmitted to the detection end of the first dial indicator 507 through the first connecting rod 5011. The first dial indicator 507 displays the maximum sway value and fluctuation, and records the data.

[0048] As the tire continues to rotate one revolution, the roundness deviation of the tire's outer circle will push the detection belt 604 and tension wheel 603, causing the moving block 601 to slide. This deviation is transmitted to the detection end of the second dial indicator 610 via the second connecting rod 6011. The second dial indicator 610 displays the roundness deviation value and records the data.

[0049] 4. Loosen the tire: Turn the handwheel 403 clockwise to move the movable seat 3 away from the upright plate 2 and remove the tire that has been inspected.

[0050] Equipment reset: Ensure all components return to their initial positions, zero the first dial indicator 507 and the second dial indicator 610, clean impurities from the equipment surface, and prepare for the next test.

[0051] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
