Description

Technical Field

[0001] This invention relates to the field of electric vehicle protection and testing technology, specifically to an electric vehicle protection and testing device and its usage method. Background Technology

[0002] Electric vehicles are becoming increasingly common on the road as new energy vehicles. As electric vehicles, they are more economical for consumers than traditional energy vehicles that use gasoline. However, as a means of transportation, electric vehicles still carry the risk of traffic accidents. Compared to traditional energy vehicles, electric vehicles usually have battery modules installed at the bottom. When these battery modules are involved in a traffic accident and are subjected to force and collision, they will inevitably deform. During this process, the safety performance of the battery modules will be tested.

[0003] To test the protective capabilities of battery modules in electric vehicles, some automakers conduct pressure tolerance tests on the battery modules. This involves deforming the battery module by squeezing it, and then testing its functionality by applying power. During the squeezing process, the battery pack needs to be stably placed on a platform; otherwise, the battery module may become misaligned or even shift under pressure, making the pressure tolerance test ineffective, wasting battery modules, and reducing testing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an electric vehicle protection testing device and its usage method, which has the advantage of easy fixation. It solves the problem that in order to test the protection capability of battery modules in electric vehicles, some car manufacturers conduct pressure resistance tests on the battery modules. By squeezing the battery modules to deform them, and then testing whether the battery modules can be used normally by powering them on, the battery pack needs to be stably placed on the platform during the squeezing process. Otherwise, the battery modules may become misaligned or even shift under pressure, resulting in the ineffective pressure resistance test, wasting battery modules and reducing testing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric vehicle protection detection device, comprising a mounting plate, a support plate fixedly connected to the front of the mounting plate, a push cylinder fixedly connected to both ends of the back of the support plate, a moving plate fixedly connected to the output end of the push cylinder, a pressing block fixedly connected to the back of the moving plate, a first connecting block fixedly connected to both sides of the front of the moving plate, a second connecting block fixedly connected to the end of the first connecting block away from the moving plate, a rack fixedly connected to the end of the second connecting block away from the first connecting block, fixing blocks provided on both sides of the mounting plate, a threaded sleeve movably connected to the top of the fixing block, a gear ring fixedly connected to the surface of the threaded sleeve, the gear ring meshing with the bottom of the rack, a threaded rod threadedly connected to the inner cavity of the threaded sleeve, a limit plate movably connected to one end of the threaded rod via a bearing, a bottom of the limit plate movably connected to the top of the mounting plate, and a rotating disk movably connected to one end of the top of the mounting plate.

[0006] Preferably, the bottom of the mounting plate is fixedly connected to a mounting frame, and one end of the fixing block is fixedly connected to the mounting frame.

[0007] Preferably, electric push rods are fixedly connected to both sides of the bottom of the inner cavity of the mounting frame, and a first lifting plate is fixedly connected to the output end of the electric push rod. A second lifting plate is fixedly connected to one side of each of the two first lifting plates.

[0008] Preferably, a rotary cylinder is fixedly connected to the top of the second lifting plate, and the output end of the rotary cylinder is fixedly connected to the bottom of the rotating disk.

[0009] Preferably, anti-slip pads are fixedly connected to the front and rear ends of the top of the first lifting plate, and anti-slip pads are fixedly connected to all four sides of the top of the mounting plate.

[0010] Preferably, a limiting circular plate is fixedly connected to the end of the threaded rod away from the limiting plate, and sliding grooves are provided on both sides of the top front end of the mounting plate. A slider is slidably connected to the inner cavity of the sliding groove, and the top of the slider is fixedly connected to the moving plate.

[0011] Preferably, the steps for its use are as follows:

[0012] A. First, place the battery module to be tested on the top of the mounting plate, which is also on top of the rotating disk. After that, start the push cylinder through the external controller. The output end of the push cylinder pushes the moving plate and the extrusion block to move on the top of the mounting plate. While the moving plate moves, it drives the slide to move along the inner cavity of the limiting circular plate. When the extrusion block contacts the battery module, the push cylinder continues to push the moving plate and the extrusion block to extrude the battery module, thereby deforming the battery module under force. After the push cylinder has completed the extrusion of the battery module, it can be controlled to drive the moving plate, the extrusion block and the slide to reset and release the extrusion of the battery module. At this time, use an external connection wire to connect to the battery module and continue to test the performance of the battery module to determine whether the battery module can continue to be used normally after being extruded.

[0013] B. Next, while the cylinder pushes the moving plate, the extrusion block, and the slide along the inner cavity of the limiting circular plate, the moving plate also drives the first connecting block, the second connecting block, and the rack to move. The movement of the rack drives the gear ring to rotate, the rotation of the gear ring drives the threaded sleeve to rotate, and the rotation of the threaded sleeve drives the threaded rod to move along the inner cavity of the threaded sleeve. While the threaded rod is moving, it pushes the limiting plate to move, so that the limiting plate follows the movement of the moving plate and the extrusion block to limit and clamp the battery module located at the top of the rotating disk, thereby preventing the battery module from deviating during the extrusion process, thus increasing the stability of the equipment when testing the battery module and increasing the testing efficiency of the equipment.

[0014] C. Finally, when it is necessary to place or remove the battery module, the electric push rod can be activated by the external controller. The output end of the electric push rod pushes the first lifting plate, the second lifting plate, and the rotary cylinder to move upward. The rotary cylinder pushes the rotating disk to move upward, thereby adjusting the height of the battery module. If it is necessary to adjust the direction of the battery module, the rotary cylinder can be activated by the external controller. The output end of the rotary cylinder drives the rotating disk to rotate, and drives the battery module to rotate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention comprises a mounting plate, a support plate, a pushing cylinder, a moving plate, a pressing block, a first connecting block, a second connecting block, a rack, a fixing block, a threaded sleeve, a gear ring, a threaded rod, a limiting plate, and a rotating disk. The support plate supports the pushing cylinder, which provides power for the movement of the moving plate and the pressing block. The pressing block can perform pressure testing on the battery module located at the top of the rotating disk, compressing the battery module. The first and second connecting blocks move with the moving plate, causing the rack to shift. The rack rotates the gear ring, which in turn rotates the threaded sleeve, thereby driving the threaded rod. The rod and limit plate are displaced and clamped to the battery module. This solves the problem that some car manufacturers conduct pressure resistance tests on battery modules in electric vehicles to test their protective capabilities. The battery module is deformed by squeezing it, and then the power-on test is conducted to test whether the battery module can be used normally. However, during the squeezing process, the battery pack needs to be stably placed on the platform. Otherwise, the battery module may be misaligned or even shifted when squeezed, which will make the pressure resistance test ineffective, resulting in wasted battery module testing and reduced testing efficiency.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0024] Please see Figure 1-4An electric vehicle protection detection device includes a mounting plate 1, a support plate 2 fixedly connected to the front of the mounting plate 1, push cylinders 3 fixedly connected to both ends of the back of the support plate 2, a movable plate 4 fixedly connected to the output end of the push cylinders 3, a pressing block 5 fixedly connected to the back of the movable plate 4, first connecting blocks 6 fixedly connected to both sides of the front of the movable plate 4, a second connecting block 7 fixedly connected to the end of the first connecting block 6 away from the movable plate 4, a rack 8 fixedly connected to the end of the second connecting block 7 away from the first connecting block 6, and fixing blocks 9 provided on both sides of the mounting plate 1. A threaded sleeve 10 is movably connected to the top of block 9. A gear ring 11 is fixedly connected to the surface of the threaded sleeve 10. The gear ring 11 meshes with the bottom of the rack 8. A threaded rod 12 is threadedly connected to the inner cavity of the threaded sleeve 10. One end of the threaded rod 12 is movably connected to a limit plate 13 via a bearing. The bottom of the limit plate 13 is movably connected to the top of the mounting plate 1. A rotating disk 14 is movably connected to one end of the top of the mounting plate 1. The mounting plate 1, support plate 2, push cylinder 3, moving plate 4, pressing block 5, first connecting block 6, second connecting block 7, rack 8, fixing block 9, and threaded... The sleeve 10, gear ring 11, threaded rod 12, limiting plate 13, and rotating disk 14 are all included. Support plate 2 supports the push cylinder 3, which provides power for the movement of the moving plate 4 and the extrusion block 5. The extrusion block 5 can perform pressure testing on the battery module located on top of the rotating disk 14, causing the battery module to be extruded. The first connecting block 6 and the second connecting block 7 move with the moving plate 4, causing the rack 8 to shift. The rack 8 rotates the gear ring 11, which in turn rotates the threaded sleeve 10, thereby causing the threaded rod 12 and the limiting plate 13 to shift. The process involves moving and clamping the battery module, which solves the problem that some automakers conduct pressure tolerance tests on battery modules in electric vehicles to test their protective capabilities. This involves deforming the battery module by squeezing it and then testing its functionality by applying power. However, during the squeezing process, the battery pack needs to be stably placed on a platform; otherwise, the battery module may become misaligned or even shift under pressure, making the pressure tolerance test ineffective, wasting battery modules, and reducing testing efficiency.

[0025] Specifically, the bottom of the mounting plate 1 is fixedly connected to the mounting frame 15, and one end of the fixing block 9 is fixedly connected to the mounting frame 15. By setting the mounting frame 15, the mounting plate 1 is supported, and the electric push rod 16, the first lifting plate 17, the second lifting plate 18 and the rotary cylinder 19 are protected.

[0026] Specifically, electric push rods 16 are fixedly connected to both sides of the bottom of the inner cavity of the mounting frame 15. The output end of the electric push rod 16 is fixedly connected to a first lifting plate 17. A second lifting plate 18 is fixedly connected to the opposite side of the two first lifting plates 17. By setting the electric push rod 16, the first lifting plate 17 and the second lifting plate 18, the electric push rod 16 can drive the first lifting plate 17, the second lifting plate 18 and the second lifting plate 18 to adjust their height.

[0027] Specifically, a rotary cylinder 19 is fixedly connected to the top of the second lifting plate 18. The output end of the rotary cylinder 19 is fixedly connected to the bottom of the rotating disk 14. By setting the rotary cylinder 19, the rotary cylinder 19 can drive the rotating disk 14 and the battery module to rotate.

[0028] Specifically, anti-slip pads 20 are fixedly connected to the front and rear ends of the top of the first lifting plate 17, and anti-slip pads 20 are fixedly connected to all four sides of the top of the mounting plate 1. By setting anti-slip pads 20, the anti-slip ability of the surface of the mounting plate 1 is increased, and the battery module is further allowed to slide on the surface of the mounting plate 1.

[0029] Specifically, a limiting circular plate 21 is fixedly connected to one end of the threaded rod 12 away from the limiting plate 13. Slide grooves 22 are provided on both sides of the top front end of the mounting plate 1. A slider 23 is slidably connected to the inner cavity of the slide groove 22. The top of the slider 23 is fixedly connected to the moving plate 4. By setting the limiting circular plate 21, the slide groove 22 and the slider 23, the limiting circular plate 21 prevents the threaded rod 12 from being displaced out of the inner cavity of the threaded sleeve 10 at one time. The slide groove 22 and the slider 23 limit the movement of the moving plate 4 and the extrusion block 5.

[0030] Specifically, the steps for using it are as follows:

[0031] A. First, place the battery module to be tested on the top of the mounting plate 1, and on top of the rotating disk 14. After completion, start the push cylinder 3 through the external controller. The output end of the push cylinder 3 pushes the moving plate 4 and the pressing block 5 to move on the top of the mounting plate 1. While the moving plate 4 moves, it drives the slide 22 to move along the inner cavity of the limiting circular plate 21. When the pressing block 5 contacts the battery module, the push cylinder 3 continues to push the moving plate 4 and the pressing block 5 to perform the pressing operation on the battery module, so that the battery module is deformed by force. After the pushing force of the push cylinder 3 completes the pressing of the battery module, the push cylinder 3 can be controlled to drive the moving plate 4, the pressing block 5 and the slide 22 to reset and release the pressing of the battery module. At this time, use an external connection wire to connect to the battery module and continue to test the performance of the battery module to determine whether the battery module can continue to be used normally after being pressed by force.

[0032] B. Next, while the cylinder 3 pushes the moving plate 4, the extrusion block 5, and the slide 22 to move along the inner cavity of the limiting circular plate 21, the moving plate 4 also drives the first connecting block 6, the second connecting block 7, and the rack 8 to move. The movement of the rack 8 drives the gear ring 11 to rotate, the rotation of the gear ring 11 drives the threaded sleeve 10 to rotate, and the rotation of the threaded sleeve 10 drives the threaded rod 12 to move along the inner cavity of the threaded sleeve 10. While the threaded rod 12 is moving, it pushes the limiting plate 13 to move, so that the limiting plate 13 follows the movement of the moving plate 4 and the extrusion block 5 to limit and clamp the battery module located on the top of the rotating disk 14, thereby preventing the battery module from deviating during the extrusion process, thus increasing the stability of the equipment when detecting the battery module and increasing the detection efficiency of the equipment.

[0033] C. Finally, when it is necessary to place or remove the battery module, the electric push rod 16 can be activated by the external controller. The output end of the electric push rod 16 pushes the first lifting plate 17, the second lifting plate 18 and the rotary cylinder 19 to move upward. The rotary cylinder 19 pushes the rotating disk 14 to move upward, thereby adjusting the height of the battery module. If it is necessary to adjust the direction of the battery module, the rotary cylinder 19 can be activated by the external controller. The output end of the rotary cylinder 19 drives the rotating disk 14 to rotate, and drives the battery module to rotate.
