Description

Technical Field

[0001] This utility model relates to a testing fixture for the insulation of the side panel of a new energy vehicle battery, belonging to the field of testing fixture technology. Background Technology

[0002] The battery side panel insulation testing fixture for new energy vehicles is a specialized tool used to test the insulation performance of the battery side panels. The battery system is one of the core components of a new energy vehicle, and the insulation performance of the battery side panels is crucial to ensuring the safe operation of the battery. Good insulation can prevent battery leakage, short circuits, and other faults, reduce safety risks, and improve the reliability and stability of the vehicle.

[0003] A handheld transmission line insulation detection device, Chinese Patent No. CN210690717U, comprises a wave-concentrating cover, an ultrasonic channel conditioning module, a laser, a camera, an LCD screen, a battery compartment, an ultrasonic sensor, a CPU processing module, and a rotating device. This handheld transmission line insulation detection device obtains partial discharge ultrasonic signals through the wave-concentrating cover and ultrasonic sensor, and acquires images of electrical equipment through the camera. These images are then displayed on the rotatable LCD screen, enabling remote monitoring of electrical equipment faults and defects. The device also allows for fault location using the laser, and provides fault recording and video evidence collection functions, thereby improving work efficiency.

[0004] After the battery side panel insulation testing fixture for new energy vehicles is tested by handheld equipment, the multiple test wirings are not easy to store. The scattered wirings are more susceptible to external pulling, squeezing or wear. The improperly stored wirings may come into contact with other conductive objects, increasing the risk of short circuits and electric shocks, especially in humid environments or environments with flammable materials, where this risk is more serious.

[0005] To address this, a tooling for testing the insulation of the side panel of a new energy vehicle battery is proposed. Utility Model Content

[0006] In view of this, the present invention provides a tooling for testing the insulation of the side panel of a new energy vehicle battery, in order to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A tooling for testing the insulation of the side panel of a new energy vehicle battery includes a drop-proof base plate. A handheld testing device is fixedly connected to the upper front side of the drop-proof base plate. An extension plate is fixedly connected to the upper rear side of the drop-proof base plate. A pair of winding assemblies are provided at the upper end of the extension plate. The winding assembly includes two symmetrical circular plates arranged vertically and vertically. A telescopic vertical rod is fixedly connected to one end of the two symmetrical circular plates that are close to each other. A plurality of locking rods arranged in an annular equidistant pattern are fixedly connected to the lower end of the upper symmetrical circular plate. A plurality of annular equidistant ring-shaped slots are opened at the upper end of the lower symmetrical circular plate. The plurality of locking rods engage with the annular slots directly below them. A testing wiring is fixedly connected to the input end of the handheld testing device. The testing wiring is wound inside the winding assembly.

[0008] More preferably, the detection wiring is located between the telescopic vertical rod and the engaging plug, and the lower end of the engaging plug is fixedly connected to an alignment tip.

[0009] More preferably, the pointed end is inserted into the circular bayonet, and a through slot is provided in the middle of the engaging rod.

[0010] More preferably, a metal push-pull plate is slidably connected to the inner end of the through slot, and the metal push-pull plate is close to the telescopic vertical rod while one end is fixedly connected to multiple flexible horizontal inserts.

[0011] More preferably, the multiple flexible transverse inserts are arranged at equal intervals from top to bottom, and the outer ends of the flexible transverse inserts are fixedly connected with multiple protruding external particles.

[0012] More preferably, the flexible transverse insertion rod extends into the transverse gap of the detection wiring wound around the outside of the telescopic vertical rod, and an electromagnetic block is fixedly connected to the upper inner wall of the through slot.

[0013] More preferably, the electromagnetic block is magnetically connected to the metal push-pull plate, and a spring is fixedly connected between the metal push-pull plate and the through slot.

[0014] More preferably, the spring is located on the side of the electromagnetic block, and the lower end of the anti-fall base plate is fixedly connected to an anti-slip bottom layer.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] 1. This solution allows the extended test wiring to be wound around the outside of the telescopic vertical rod inside the winding assembly. The symmetrical circular plate above presses down the telescopic vertical rod, causing multiple locking pins to engage with the corresponding circular slots. This limits and fixes the wound telescopic vertical rod. Simultaneously, the alignment tips below the locking pins improve the accuracy of the connection, allowing for quick and easy organization and storage of the test wiring. This prevents it from being pulled, squeezed, or worn by external forces, reducing the occurrence of damage to the outer sheath and breakage of internal wires, thus extending the service life of the test wiring. The neatly stored test wiring will not come into accidental contact with other conductive objects, reducing the risk of short circuits and electric shock.

[0017] 2. After the locking rod is pressed down to form a protective space outside the winding test wiring, the metal push-pull plate outside the locking rod can be pressed to make it penetrate through the slot, so that multiple flexible transverse rods can be inserted into the transverse gap of the test wiring. The protruding outer particles of the flexible transverse rods can improve the locking performance of the winding test wiring, making it less likely to loosen during transportation.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0026] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-3 As shown, this utility model embodiment provides a new energy vehicle battery side panel insulation testing fixture, including a drop-proof base plate 2. A handheld testing device 1 is fixedly connected to the upper front side of the drop-proof base plate 2, and an extension plate 4 is fixedly connected to the upper rear side of the drop-proof base plate 2. A pair of winding assemblies 5 are provided on the upper end of the extension plate 4. The winding assembly 5 includes two symmetrical circular plates 11 arranged vertically and vertically. A telescopic vertical rod 7 is fixedly connected to one end of the two symmetrical circular plates 11 that is close to each other. A plurality of locking rods 8 arranged in an annular equidistant pattern are fixedly connected to the lower end of the upper symmetrical circular plate 11. A plurality of annular equidistant ring-shaped slots 9 are opened on the upper end of the lower symmetrical circular plate 11. The plurality of locking rods 8 and the corresponding annular slots 9 below them engage with each other.

[0030] The input end of the handheld testing device 1 is fixedly connected to the testing cable 6, which is wound inside the winding assembly 5. The testing cable 6 is located between the telescopic vertical rod 7 and the locking rod 8. The lower end of the locking rod 8 is fixedly connected to the alignment tip 10, which passes through the circular bayonet 9. The lower end of the anti-fall base plate 2 is fixedly connected to the anti-slip bottom layer 3.

[0031] Example 2

[0032] like Figure 3-5As shown, in one embodiment, a through slot 12 is provided in the middle of the locking rod 8. A metal push-pull plate 13 is slidably connected to the inner end of the through slot 12. A plurality of flexible horizontal inserts 14 are fixedly connected to one end of the metal push-pull plate 13 near the telescopic vertical rod 7. The plurality of flexible horizontal inserts 14 are equidistant from top to bottom. A plurality of protruding external particles 15 are fixedly connected to the outer end of the flexible horizontal inserts 14. The flexible horizontal inserts 14 extend into the transverse gap of the detection wiring 6 wrapped around the outside of the telescopic vertical rod 7. An electromagnetic block 16 is fixedly connected to the upper inner wall of the through slot 12. The electromagnetic block 16 is magnetically connected to the metal push-pull plate 13. A spring 17 is fixedly connected between the metal push-pull plate 13 and the through slot 12. The spring 17 is located on the side of the electromagnetic block 16.

[0033] Multiple flexible transverse inserts 14 are inserted into the transverse gaps of the test wiring 6. The protruding outer pegs 15 on the outside of the flexible transverse inserts 14 can improve the locking performance of the test wiring 6 in the winding state, making it less likely to loosen during transportation. When the test wiring 6 needs to be removed, the electromagnetic block 16 can be de-energized using the control terminal, and then the metal push-pull plate 13 will rebound through the spring 17, causing the flexible transverse inserts 14 to push out to the inner position of the locking inserts 8. This will smoothly lift the symmetrical circular plate 11, allowing the test wiring 6 to be easily removed for subsequent testing operations.

[0034] In operation, this invention works as follows: After connecting the handheld testing device 1 to the testing cable 6, the testing probe at the output end of the testing cable 6 is gently placed in contact with the designated position on the side panel of the new energy vehicle battery. The handheld testing device 1 automatically applies voltage and measures the current flowing through the battery side panel. After the test is completed, the handheld testing device 1 displays the test results on the screen, allowing the operator to determine whether the insulation performance of the battery side panel is qualified. After the test, the operator can wind the extended testing cable 6 around the outside of the telescopic vertical rod 7 inside the winding assembly 5, and press down the symmetrical circular plate 11 above the telescopic vertical rod 7, causing multiple locking pins 8 to engage into the corresponding circular slots 9, thus limiting and fixing the wound telescopic vertical rod 7. At the same time, during engagement, the alignment tip 10 below the locking pin 8 can improve the two The precise docking between the components allows for quick and easy organization of the test wiring 6, preventing it from being pulled, squeezed, or worn by external forces. This reduces the occurrence of damage to the outer sheath and breakage of internal wires, extending the service life of the test wiring 6. The neatly organized test wiring 6 will not come into accidental contact with other conductive objects, reducing the risk of short circuits and electric shock. Furthermore, after the locking rod 8 presses down on the outside of the wound test wiring 6 to form a protective space, the metal push-pull plate 13 outside the locking rod 8 can be pressed to penetrate the slot 12, allowing multiple flexible transverse rods 14 to be inserted into the transverse gaps of the test wiring 6. The protruding outer pegs 15 on the outside of the flexible transverse rods 14 can improve the locking performance of the outside of the wound test wiring 6, making it less likely to loosen during transportation.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
