Description

Technical Field

[0001] This utility model relates to the field of automotive testing rack technology, and more specifically, to a testing rack for testing the power of new energy vehicles. Background Technology

[0002] New energy vehicles are automobiles that use a single battery as their energy storage and power source. The battery provides electrical energy to the electric motor, which in turn drives the motor and propels the vehicle. Because new energy vehicles use electricity, they avoid the exhaust pollution caused by gasoline-powered vehicles. Before a new energy vehicle can be used, its power system typically needs to be tested and rated. This testing usually involves a roller drive system on a test bench to assist in the testing process.

[0003] However, the existing test racks mostly have fixed roller drive systems, which means that the position of the drive system cannot be freely adjusted according to the wheelbase of the car, affecting the adaptability of the test rack when testing different types of new energy vehicles. Furthermore, after the test is completed, because the wheels cannot leave the rollers, when the new energy vehicle reverses out of the test frame, it is easy for it to rotate synchronously with the rollers inside the roller drive system, making it unable to leave the test and affecting normal use. Utility Model Content

[0004] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides a test frame for testing the power of new energy vehicles, thereby solving the technical problem mentioned in the background art that the roller drive system of existing test frames is mostly fixedly installed, which makes it impossible to freely adjust the position of the drive system according to the wheelbase of the vehicle.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a test frame for testing the power of new energy vehicles, comprising a support frame, a first drive assembly fixedly mounted on the upper surface and on both sides of the support frame, an adjustment hole opened on one side of the first drive assembly and on the upper surface of the support frame, a second drive assembly slidably mounted inside the adjustment hole, a pad mounted on the upper surface and on both sides of the second drive assembly, an adjustment groove opened on both sides of the adjustment hole and on the upper surface of the support frame, the pad mounted inside the adjustment groove, a crossbeam fixedly mounted between the two second drive assemblies, a bearing seat mounted in the middle of the support frame and on both sides of the adjustment hole, a lead screw rotatably mounted in the middle of the bearing seat, the lead screw being threadedly connected to the crossbeam, a motor fixedly mounted at one end of the lead screw and on the outer wall of the bearing seat, a power roller mounted inside the first drive assembly and the second drive assembly, two sets of the power rollers, and a lifting plate movably mounted in the middle of each set.

[0006] The present invention is further configured such that jacks are fixedly provided on the lower end faces of the first drive assembly and the second drive assembly, and the output ends of the jacks are fixedly connected to the bottom of the lifting plate. Guide bars are fixedly provided on the inner walls of the first drive assembly and the second drive assembly and on both sides, and grooves are provided on the guide bars. Slider blocks are provided at both ends of the lifting plate, and the sliders are slidably installed with the grooves to facilitate contact between the lifting plate and the front and rear wheels of the car, so as to facilitate the car to go down to the lower end of the bracket.

[0007] The present invention is further provided that the upper surface of the lifting plate is provided with anti-slip texture, which facilitates the increase of friction between the tire and the lifting plate.

[0008] The present invention is further configured such that a baffle is fixedly provided at one end of the bracket, and guide rods are slidably provided on the outer wall of the baffle and at the four corners. One end of each guide rod passes through the baffle and is provided with an anti-collision plate. A buffer spring is provided on the inner wall of the anti-collision plate and at the four corners. The other end of each buffer spring is fixedly connected to the baffle, which facilitates the protection of the front end of the new energy vehicle.

[0009] The present invention is further provided that the inner wall of the anti-collision plate is provided with rubber blocks, and the rubber blocks are provided in multiple and evenly distributed, so as to buffer the impact force received by the anti-collision plate.

[0010] The present invention is further configured such that an inclined slope is fixedly provided at the other end of the bracket, and an anti-slip strip is provided on the inclined slope to increase the friction between the tire and the inclined slope.

[0011] The present invention is further provided that protective plates are fixed on both sides of the bracket to facilitate the protection of both sides of the new energy vehicle.

[0012] The present invention is further provided with rubber protrusions on the outer wall of the anti-collision plate, which helps to reduce the reaction force on the new energy vehicle and thus protect the new energy vehicle.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a test frame for testing the power of new energy vehicles, which has the following advantages: 1. By setting up adjustment holes, a second drive assembly, a crossbeam, and a motor, the user can control the motor to move the lead screw, which in turn moves the crossbeam and the second drive assembly to adjust the distance between the second drive assembly and the first drive assembly. This facilitates testing of new energy vehicles with different wheelbases. Furthermore, by setting up a pad and an adjustment groove, the adjustment holes can be covered to facilitate the normal operation of the new energy vehicle.

[0014] 2. By setting up a lifting plate, jacks, and anti-slip textures, after the test is completed, the user can control the jacks to move the lifting plate upwards so that it contacts the front and rear wheels of the new energy vehicle. At this time, the car is started to reverse to facilitate leaving the support. Furthermore, by setting up sliders and guide bars, the two ends of the lifting plate can be guided to make it more stable during lifting and lowering.

[0015] 3. By setting up baffles, guide rods, and anti-collision plates, when an operational error causes the new energy vehicle to move forward, the anti-collision plates and baffles can limit the vehicle to prevent it from crashing off the support, thereby reducing losses. In addition, by setting up buffer springs and rubber blocks, the impact force on the new energy vehicle due to collision can be reduced, thus protecting the new energy vehicle.

An adjustment hole 3 is opened on one side of the first drive assembly 2 and on the upper surface of the support 1. A second drive assembly 4 is slidably mounted inside the adjustment hole 3. A pad 5 is provided on the upper surface and both sides of the second drive assembly 4. An adjustment groove 6 is opened on both sides of the adjustment hole 3 and on the upper surface of the support 1. The pad 5 is located inside the adjustment groove 6. A crossbeam 7 is fixedly mounted between the two second drive assemblies 4. A bearing seat 8 is provided in the middle of the support 1 and on both sides of the adjustment hole 3. A lead screw 9 is rotatably mounted in the middle of the bearing seat 8 and is threadedly connected to the crossbeam 7. A motor 10 is fixedly mounted at one end of the lead screw 9 on the outer wall of the bearing seat 8. Power rollers 11 are provided inside both the first drive assembly 2 and the second drive assembly 4. Two sets of power rollers 11 are provided, and a lifting plate 12 is movably mounted in the middle of each set. Protective plates 24 are fixedly mounted on both sides of the support 1.

[0022] In this embodiment, jacks 13 are fixedly provided on the lower end faces of the first drive assembly 2 and the second drive assembly 4. The output ends of the jacks 13 are fixedly connected to the bottom of the lifting plate 12. Guide strips 14 are fixedly provided on the inner walls of the first drive assembly 2 and the second drive assembly 4 and on both sides. Slide grooves 15 are provided on the guide strips 14. Slider blocks 16 are provided at both ends of the lifting plate 12. The sliders 16 are slidably installed with the slide grooves 15. Anti-slip textures 17 are provided on the upper end face of the lifting plate 12.

[0023] More specifically, the user can control the motor 10 to move the lead screw 9, which in turn moves the crossbeam 7 and the second drive assembly 4, thereby adjusting the distance between the second drive assembly 4 and the first drive assembly 2. This facilitates testing of new energy vehicles with different wheelbases. Furthermore, by setting the pad 5 and the adjustment groove 6, the adjustment hole 3 can be blocked to facilitate the normal driving of the new energy vehicle. After the test is completed, the user can control the jack 13 to move the lifting plate 12 upward so that it contacts the front and rear wheels of the new energy vehicle. At this time, the vehicle is started and reversed to facilitate leaving the support 1. Furthermore, by setting the slider 16 and the guide bar 14, the two ends of the lifting plate 12 can be guided to make it more stable during lifting and lowering.

[0024] Please see Figure 1 , Figure 4 and Figure 5 As an implementation method for protecting the front end of a new energy vehicle: a baffle 18 is fixedly provided at one end of the bracket 1, and guide rods 19 are slidably provided on the outer wall of the baffle 18 at the four corners. One end of each guide rod 19 passes through the baffle 18 and is provided with a crash plate 20. A buffer spring 21 is provided on the inner wall of the crash plate 20 at the four corners. The other end of each buffer spring 21 is fixedly connected to the baffle 18. A rubber block 22 is provided on the inner wall of the crash plate 20. Multiple rubber blocks 22 are provided and are evenly distributed. A rubber protrusion 25 is provided on the outer wall of the crash plate 20.

[0025] Specifically, when an operational error causes the new energy vehicle to move forward, the anti-collision plate 20 and the baffle 18 can limit the vehicle to prevent it from falling off the support 1, thereby reducing the loss. Furthermore, by setting the buffer spring 21 and the rubber block 22, the impact force on the new energy vehicle due to the collision can be reduced to protect the new energy vehicle.

[0027] Specifically, the inclined ramp 23 can guide the new energy vehicle to successfully climb onto the upper part of the support 1.

[0028] In summary, when using the overall equipment: the user can drive the new energy vehicle under test to the upper end of the bracket 1, and make its front and rear wheels contact the power rollers 11 inside the second drive assembly 4 and the first drive assembly 2. Then, control the first drive assembly 2 and the second drive assembly 4 to make the power rollers 11 drive the front and rear wheels to rotate. The subsequent test data will be transmitted to an external display device to achieve the test effect. After the test is completed, the user can control the jack 13 to move the lifting plate 12 upward so that it contacts the front and rear wheels of the new energy vehicle. At this time, start the car to reverse, so as to facilitate leaving the bracket 1 and help test other new energy vehicles. And by setting the slider 16 and guide... The 14 strip can guide both ends of the lifting plate 12 to make it more stable during lifting. Before testing, the motor 10 can be controlled to move the lead screw 9 to drive the crossbeam 7 and the second drive assembly 4 to adjust the distance between the second drive assembly 4 and the first drive assembly 2, so as to facilitate testing of new energy vehicles with different wheelbases. When the new energy vehicle moves forward due to operational error, the anti-collision plate 20 and the baffle 18 can limit the vehicle to prevent it from falling off the support 1, thereby reducing the loss. In addition, by setting the buffer spring 21 and the rubber block 22, the impact force on the new energy vehicle due to collision can be reduced to protect the new energy vehicle.
