Description
Technical Field
[0001] This utility model belongs to the field of battery pack vibration testing technology, and specifically relates to a clamping device for testing the vibration of a new energy vehicle battery pack. Background Technology
[0002] With the rapid development of the new energy vehicle industry, the safety and reliability testing of battery packs, as core components, is of paramount importance. Vibration testing is a crucial step in simulating vehicle driving conditions, requiring the battery pack to be fixed to a vibration table using clamping devices to apply dynamic loads.
[0003] Currently, most mainstream clamping devices (such as hydraulic clamps and bolt-fixed frames) adopt a rigid structure design, with a fixed clamping range, and are only suitable for battery packs of specific sizes. Since the shapes and sizes of battery packs of different car models vary greatly (such as square, rectangular or irregular structures), it is necessary to replace the corresponding clamping components when testing different models, and manually disassemble and reassemble the clamping module, which is cumbersome and time-consuming. Utility Model Content
[0004] To address the problem that testing different models of battery packs requires replacing the corresponding clamping components, manually disassembling and reassembling the clamping module, which is cumbersome and time-consuming due to the significant differences in shape and size (such as square, rectangular, or irregular structures), this utility model proposes a clamping device for testing the vibration of new energy vehicle battery packs, in order to overcome the aforementioned technical problems in existing related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a vibration testing clamping device for a new energy vehicle battery pack, including a base. The base is equipped with a rotating component and a displacement component. The rotating component is equipped with a telescopic component inside, and a clamping component is equipped on the outer surface of the telescopic component. The rotating component is used to drive the telescopic component and the clamping component to rotate. The displacement component is used to drive the clamping component to move. The telescopic component is used to drive the clamping component to reset. There are multiple sets of both the telescopic component and the clamping component.
[0007] Furthermore, the rotating assembly includes a first rotating shaft, a first synchronous pulley is fixedly mounted on the outer surface of the first rotating shaft, a synchronous belt is mounted on the outer surface of the first synchronous pulley, a second synchronous pulley is connected to the first synchronous pulley via the synchronous belt, a second rotating shaft is fixedly mounted on the outer surface of the second synchronous pulley, both the first rotating shaft and the second rotating shaft are rotatably connected to the base, and a rotating platform is fixedly connected to the top of both the first rotating shaft and the second rotating shaft.
[0008] Furthermore, the telescopic assembly includes a fixed cylinder, which is fixedly connected inside the rotating platform. A telescopic slide rod and a limiting plate are slidably connected inside the fixed cylinder. One end of the telescopic slide rod is fixedly connected to the limiting plate, and a connecting plate is fixedly installed at the other end of the telescopic slide rod. A first spring is fixedly connected to the outer surface of the limiting plate, and one end of the first spring is fixedly connected inside the fixed cylinder.
[0009] Furthermore, the clamping assembly includes a square plate, which is fixedly mounted on the outer surface of the connecting plate. A T-shaped block is slidably connected inside the square plate. A second spring is fixedly connected to the bottom of the T-shaped block. A lower pressure plate is fixedly connected to the top of the T-shaped block. The lower end of the second spring is fixedly connected to the inside of the square plate. A bolt is threaded onto the outer surface of the lower pressure plate.
[0010] Furthermore, the displacement component includes a guide rail, which is fixedly connected inside the base. A bidirectional screw is rotatably connected inside the guide rail, and a guide rod is fixedly connected inside the guide rail. A push plate is slidably connected inside the guide rail. There are two sets of push plates, both sets of push plates are threadedly connected to the bidirectional screw, and both sets of push plates are slidably connected to the guide rod.
[0011] Furthermore, handwheels are fixedly connected to the outer surfaces of both the rotating platform and the bidirectional screw.
[0012] Furthermore, the telescopic slide rod, connecting plate, and square plate are all fixedly installed using bolts.
[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model connects a rotating component and a clamping component. The rotating component rotates within the base, and multiple sets of clamping components are provided on the outer surface of the rotating component. When the new energy vehicle battery pack is placed on the base, the rotating component is pushed to drive the clamping components to rotate. The appropriate clamping components are selected and positioned on both sides of the new energy vehicle battery pack. Then, the clamping components are pushed closer to the new energy vehicle battery pack to clamp and fix it. When dealing with different models of new energy vehicle battery packs, different clamping components can be selected by rotating the rotating component without having to disassemble and reassemble the clamping components, making it more convenient to use.
[0015] 2. This utility model connects the push plate and the square plate. The push plate drives the square plate to move, so that the two sets of square plates move closer to each other to clamp the new energy vehicle battery pack and stretch the first spring, thereby fixing the new energy vehicle battery pack. After the test is completed, the push plate moves away from the square plate. At this time, the push plate no longer applies a pushing force to the square plate. The first spring can pull the square plate back to its original position and move it away from the new energy vehicle battery pack, making it easy to remove the new energy vehicle battery pack from between the square plates.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0028] Please see Figures 1-6 As shown, this utility model is a vibration testing clamping device for a new energy vehicle battery pack, including a base 1. The base 1 is equipped with a rotating component 2 and a displacement component 5. The rotating component 2 is equipped with a telescopic component 3. The outer surface of the telescopic component 3 is equipped with a clamping component 4. The rotating component 2 is used to drive the telescopic component 3 and the clamping component 4 to rotate. The displacement component 5 is used to drive the clamping component 4 to move. The telescopic component 3 is used to drive the clamping component 4 to reset. There are multiple sets of telescopic components 3 and clamping components 4.
[0029] After placing the new energy vehicle battery pack to be tested for vibration on the base 1, push the rotating component 2 inside the base 1 to rotate. The rotating component 2 drives the clamping component 4 to rotate. Select the appropriate clamping component 4 and position it on both sides of the new energy vehicle battery pack. Then drive the displacement component 5 to move the clamping component 4. During the movement of the clamping component 4, it drives the telescopic component 3 to be stretched, so that the clamping component 4 is close to the new energy vehicle battery pack to clamp and fix it. After the fixation is completed, the vibration test can be started. After the test is completed, the displacement component 5 resets. During the reset process, the displacement component 5 separates from the clamping component 4. At this time, the telescopic component 3 can drive the clamping component 4 away from the new energy vehicle battery pack to release the limit fixation.
[0030] This invention connects a rotating component 2 and a clamping component 4. The rotating component 2 rotates within the base 1, and multiple sets of clamping components 4 are provided on the outer surface of the rotating component 2. When the new energy vehicle battery pack is placed on the base 1, the rotating component 2 is pushed to drive the clamping components 4 to rotate. A suitable clamping component 4 is selected so that it is positioned on both sides of the new energy vehicle battery pack. Then, the clamping components 4 are pushed closer to the new energy vehicle battery pack to clamp and fix it. When dealing with different models of new energy vehicle battery packs, different clamping components 4 can be selected by rotating the rotating component 2 without having to disassemble and reassemble the clamping components 4, making it more convenient to use.
[0031] In one embodiment, the rotating component 2 includes a first rotating shaft 201, a first synchronous pulley 202 fixedly mounted on the outer surface of the first rotating shaft 201, a synchronous belt 203 mounted on the outer surface of the first synchronous pulley 202, a second synchronous pulley 204 connected to the first synchronous pulley 202 via the synchronous belt 203, a second rotating shaft 205 fixedly mounted on the outer surface of the second synchronous pulley 204, both the first rotating shaft 201 and the second rotating shaft 205 being rotatably connected to the base 1, and a rotating platform 206 fixedly connected to the top of both the first rotating shaft 201 and the second rotating shaft 205.
[0032] The first rotating shaft 201 is driven to rotate, which in turn drives the first synchronous pulley 202 to rotate. The first synchronous pulley 202 drives the second synchronous pulley 204 to rotate via the synchronous belt 203. The second rotating shaft 205 on the outer surface of the second synchronous pulley 204 can rotate accordingly. At this time, the two sets of rotating platforms 206 located at the top of the first rotating shaft 201 and the second rotating shaft 205 can rotate synchronously.
[0033] In one embodiment, the telescopic component 3 includes a fixed cylinder 301, which is fixedly connected inside the rotating platform 206. A telescopic slide rod 302 and a limiting plate 303 are slidably connected inside the fixed cylinder 301. One end of the telescopic slide rod 302 is fixedly connected to the limiting plate 303, and a connecting plate 304 is fixedly installed at the other end of the telescopic slide rod 302. A first spring 305 is fixedly connected to the outer surface of the limiting plate 303, and one end of the first spring 305 is fixedly connected inside the fixed cylinder 301.
[0034] Two sets of rotating platforms 206 drive multiple sets of fixed cylinders 301 to rotate. Each set of fixed cylinders 301 drives a corresponding telescopic slide rod 302 and connecting plate 304 to rotate. When the two sets of connecting plates 304 approach each other, the connecting plates 304 drive the telescopic slide rod 302 and the limiting plate 303 to slide within the fixed cylinders 301. The limiting plate 303 stretches the first spring 305. After the thrust applied to the connecting plate 304 is released, the first spring 305 can drive the connecting plate 304 to reset. Different clamping components 4 are installed on the outer surfaces of the multiple sets of connecting plates 304. Rotating the rotating platform 206 allows selection of a suitable clamping component 4 to clamp the new energy vehicle battery pack.
[0035] In one embodiment, the clamping assembly 4 includes a square plate 401, which is fixedly mounted on the outer surface of the connecting plate 304. A T-shaped block 402 is slidably connected inside the square plate 401. A second spring 403 is fixedly connected to the bottom of the T-shaped block 402. A lower pressure plate 404 is fixedly connected to the top of the T-shaped block 402. The lower end of the second spring 403 is fixedly connected to the inside of the square plate 401. A bolt 405 is threadedly connected to the outer surface of the lower pressure plate 404.
[0036] The rotating platform 206 drives the connecting plate 304 to rotate. Select the appropriate square plate 401 and lower pressure plate 404 on the rotating platform 206 to clamp the new energy vehicle battery pack. The connecting plate 304 drives the square plate 401 to move. The square plates 401 on both sides of the new energy vehicle battery pack move closer and clamp the battery pack at the same time. Then push the lower pressure plate 404 to drive the T-shaped block 402 to move downward and compress the second spring 403. The lower pressure plate 404 presses down on the new energy vehicle battery pack. The bolt 405 passes through the lower pressure plate 404 and is threaded to the square plate 401 to fix the lower pressure plate 404. At this time, the lower pressure plate 404 clamps the new energy vehicle battery pack on the top of the base 1.
[0037] In one embodiment, the displacement component 5 includes a guide rail 501, which is fixedly connected to the inside of the base 1. A bidirectional screw 502 is rotatably connected inside the guide rail 501. A guide rod 503 is fixedly connected inside the guide rail 501. A push plate 504 is slidably connected inside the guide rail 501. There are two sets of push plates 504. Both sets of push plates 504 are threadedly connected to the bidirectional screw 502 and slidably connected to the guide rod 503.
[0038] Rotating the bidirectional screw 502, the rotational tendency of the upper push plate 504 is blocked by the guide rod 503 and the guide rail 501. At this time, the bidirectional screw 502 can drive the two sets of push plates 504 to move closer or further apart simultaneously. The push plates 504 push the square plate 401 and the lower pressure plate 404 closer together to clamp the new energy vehicle battery pack. Reversing the bidirectional screw 502 causes the push plate 504 to separate from the square plate 401. At this time, the first spring 305 pulls the connecting plate 304 and the square plate 401 to reset.
[0039] In one embodiment, for the aforementioned rotating table 206, both the outer surfaces of the rotating table 206 and the bidirectional screw 502 are fixedly connected with handwheels 6.
[0040] The handwheel 6 is designed to provide a point of force for rotating the turntable 206 and the bidirectional screw 502, making it more convenient to use.
[0041] In one embodiment, the telescopic slide bar 302, the connecting plate 304, and the square plate 401 are all fixedly installed by bolts 405.
[0042] Bolt 405 ensures a firm and reliable connection between telescopic slide bar 302, connecting plate 304 and square plate 401, while also facilitating disassembly and maintenance.
[0043] Through the above technical solution, 1. By connecting the rotating component 2 and the clamping component 4, the rotating component 2 rotates within the base 1. Multiple sets of clamping components 4 are provided on the outer surface of the rotating component 2. When the new energy vehicle battery pack is placed on the base 1, pushing the rotating component 2 causes the clamping components 4 to rotate, selecting appropriate clamping components 4 so that they are positioned on both sides of the new energy vehicle battery pack. Then, pushing the clamping components 4 closer to the new energy vehicle battery pack clamps and secures it. When dealing with different models of new energy vehicle battery packs, different clamping components 4 can be selected by rotating the rotating component 2, eliminating the need for re-selection. The newly assembled clamping assembly 4 is more convenient to use; 2. Through the connection between the push plate 504 and the square plate 401, the push plate 504 drives the square plate 401 to move, so that the two sets of square plates 401 move closer to each other to clamp the new energy vehicle battery pack and stretch the first spring 305, thereby fixing the new energy vehicle battery pack. After the test is completed, the push plate 504 moves away from the square plate 401. At this time, the push plate 504 no longer applies a pushing force to the square plate 401. The first spring 305 can pull the square plate 401 to reset and move it away from the new energy vehicle battery pack, making it easy to remove the new energy vehicle battery pack from between the square plates 401.
