Description

Technical Field

[0001] The utility model relates to the technical field of battery disassembly, in particular to a battery pack discharge device. Background Art

[0002] For environmental and economic benefits, waste batteries need to be recycled. Recycling requires disassembling the batteries, and the battery pack needs to be discharged during disassembly. During the discharge process, the connecting wire is manually connected to the battery, which is very time-consuming when used. At the same time, manual operation may cause connection errors, and the efficiency is low during discharge. In order to solve the above problems, China Patent No. CN220272583U discloses a waste battery pack discharge device, which fixes the discharge device by setting a fixed frame, and then places the battery on a workbench and moves it downward through a lifting discharge mechanism to contact the positive and negative electrodes of the battery to discharge the battery. It can be more convenient when discharging, but at the same time, during the battery pack power generation process, the battery pack may be damaged and self-ignited. At this time, the battery pack will explode, and small fragments will fly around, which can easily cause harm to the discharge personnel. In addition, the shaking of the battery pack due to the operation of the equipment or the action of external force during the discharge process will affect the stability of the connection between the electrode connector and the battery pack, and the two will be separated, affecting normal discharge. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a battery pack discharge device.

[0004] The technical solution of this utility model is as follows:

[0006] The output end of the telescopic cylinder slides through the upper end of the protective cover and extends into the protective cover. The output end of the telescopic cylinder is fixed with an electrode connector, which can be connected to the electrode assembly of the battery pack.

[0007] In order to enable the motor connector to be separated from the battery pack electrode in time when the telescopic cylinder fails, a tension spring is provided on the telescopic cylinder and is located inside the protective cover, and the two ends of the tension spring are respectively fixed to the top inside the protective cover and the upper end of the electrode connector.

[0008] In order to control the lifting of the protective cover, the lifting platform is connected to the machine body through a lifting assembly.

[0009] The specific structure of the lifting assembly is that the lifting assembly includes a driving mechanism arranged in the machine body and two screws on the machine body, and the driving mechanism can drive the screws to rotate; the upper ends of the two screws are threadedly connected with threaded barrels, the lifting platform is installed on the top of the threaded barrel, and the protective cover is connected to the threaded barrel through a connecting rod and can move up and down with it.

[0010] In order to effectively clamp and fix the battery pack in place and ensure the stability of the battery pack, cross bars are provided on both sides of the protective cover, and clamps are fixed to the opposite ends of the two cross bars and are arranged in the protective cover, and a baffle is provided at the other end. The clamps are connected to the protective cover by a spring.

[0011] In order to limit the movement of the two clamps when they do not need to clamp the battery pack, two slides are fixed on both sides of the protective cover. The slides are located on the upper and lower sides of the cross bar. Limiting members are slidably sleeved on the slides, and the four limiting members respectively abut against one side of the two baffles.

[0012] In order to be able to clamp the battery pack placed on the supporting seat and adapt to battery packs of most sizes, the distance between the cross bar and the bottom end of the protective cover is 1 / 3-2 / 3 of the height of the protective cover.

[0013] The specific transmission method adopted by the lifting structure is that the driving mechanism adopts a chain transmission method, which can drive the two screws to rotate synchronously.

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0027] Example

[0028] As mentioned in the background technology, although the battery pack discharge device in the existing patent can automatically complete the contact between the discharge mechanism and the positive and negative electrodes of the battery to complete the discharge, there are still major defects. The inventor found that during the discharge process, the battery pack will be damaged and spontaneously combust. At this time, the battery pack will explode, causing small fragments to fly, which is very likely to cause harm to personnel. In addition, when there is a problem with the stability of the battery pack during the discharge process, the connection will be disconnected, affecting normal discharge. Therefore, the inventor has improved on the basis of the existing discharge equipment and designed a new discharge device, which is explained in detail below with reference to the diagram.

[0029] This embodiment provides a battery pack discharge device, combined with Figure 1 and Figure 2, including a body 1, in which corresponding discharge equipment is installed. The discharge equipment in the body 1 can adopt the middle discharge technology of the existing technology, and the battery pack can be discharged by the cooperation of the body 1 and the electrode connector 6. A bearing seat 2 is provided in the middle of the upper end of the body 1, and the bearing seat 2 is used to place the battery pack. A lifting platform 3 is provided on the body 1, and a telescopic cylinder 4 and a protective cover 5 with an opening at the lower end are provided at the lower end of the lifting platform 3. The telescopic cylinder 4 is connected to the lower end surface of the lifting platform 3 and is located between the lifting platform 3 and the protective cover 5. The protective cover 5 is made of fire-resistant and non-conductive material, which can effectively isolate, and in order to facilitate the up and down movement of the lifting platform 3, the lifting platform 3 is connected to the body 1 through a lifting component 8.

[0030] Specifically, the lifting assembly 8 includes a driving mechanism 81 arranged in the body 1 and two screw rods 82 on the body 1. The driving mechanism 81 can drive the screw rods 82 to rotate, and a threaded tube 83 is threadedly sleeved on the upper ends of the two screw rods 82, and the lifting platform 3 is installed on the top of the threaded tube 83, and the protective cover 5 is connected to the threaded tube 83 through a connecting rod 9. Specifically, a fixed sleeve is fixedly installed on the outside of the threaded tube 83, and the fixed sleeve is connected to the connecting rod 9. The driving mechanism 81 can drive the two screw rods 82 to rotate, and then drive the fixed sleeve to move up and down with the threaded tube 83 through the thread, and then drive the lifting platform 3 to move up and down, and drive the protective cover 5 to move up and down through the connecting rod 9.

[0031] The protective cover 5 is driven downward by the driving mechanism 81, and its bottom is open, so that it can cover the battery pack placed on the supporting seat 2, and in order to improve the fire prevention effect, a fire-resistant pad 16 is arranged around the lower end of the protective cover 5, and an opening is arranged at the fire-resistant pad 16 corresponding to the position of the supporting seat 2, and the opening ensures that the protective cover 5 can pass through the battery pack and the supporting seat 2.

[0032] The driving mechanism 81 specifically adopts a chain transmission mode, combined with Figure 2 Specifically, it includes a driving motor 811 installed in the body 1, the output shaft of the driving motor 811 is connected to a driving sprocket 812, and the two sides of the driving sprocket 812 are connected to driven sprockets 814 through chains 813. The two driven sprockets 814 are respectively connected to two screw rods 82. The operation of the driving motor 811 can drive the driving sprocket 812 to rotate, and then the chain 813 drives the driven sprocket 814 to rotate, and finally the screw rod 82 is rotated.

[0033] In order to be able to drive the telescopic cylinder 4 to move up and down synchronously, the telescopic cylinder 4 is installed between the lifting platform 3 and the protective cover 5, and the telescopic cylinder 4 is fixed to the lower end of the lifting platform 3. When the screw rod 82 drives the threaded tube 83 to move up and down, the telescopic cylinder 4 is driven to move through the lifting platform 3. In order to facilitate the control of the telescopic cylinder 4, an electric control mode is adopted in this embodiment.

[0034] In this embodiment, in order to facilitate the connection with the battery pack electrodes placed on the supporting seat 2 and complete the discharge work, the output end of the telescopic cylinder 4 slides through the upper end of the protective cover 5 and extends into the protective cover 5. The output end of the telescopic cylinder 4 is fixed with an electrode connector 6, which can be connected to the electrode assembly of the battery pack, and the electrode connector 6 is connected to the discharge equipment in the body 1. The drive of the telescopic cylinder 4 can drive the electrode connector 6 to move up and down, and then can realize the connection of battery pack electrodes of different sizes. In addition, in order to ensure that the electrode connector 6 can be separated from the battery pack electrodes when the telescopic cylinder 4 is damaged, a tension spring 7 is provided on the telescopic cylinder 4, and the electrode connector 6 is located in the protective cover 5. The two ends of the tension spring 7 are respectively fixed to the top in the protective cover 5 and the upper end of the electrode connector 6. The tension spring 7 can pull the electrode connector 6 up to separate from the battery pack, thereby improving the safety of use.

[0035] Based on the above structure, combined with Figure 3 Cross bars 10 are provided on both sides of the protective cover 5, and clamps 11 are fixed to the opposite ends of the two cross bars 10. The two clamps 11 are arranged in the protective cover 5. The two cross bars 10 can limit the up and down movement of the two clamps 11, so that the two clamps 11 can maintain stable left and right movement when being driven. The two clamps 11 can clamp the two sides of the battery pack, so that the battery pack remains stable during the discharge process, thereby increasing the stability of the battery pack.

[0036] Moreover, in order to be suitable for clamping battery packs of most sizes, the distance between the cross bar 10 and the bottom end of the protective cover 5 is 1 / 3-2 / 3 of the height of the protective cover 5, so that the clamp 11 is at a suitable height, which facilitates the clamping of the battery pack and improves the practical performance of this solution.

[0037] Among them, springs 13 are sleeved on the two cross bars 10, and the opposite ends of the two springs 13 are fixedly connected to one side of the two clamps 11, and the other ends of the two springs 13 are fixedly connected to the opposite inner walls of the protective cover 5. The springs 13 are elastic. When the two cross bars 10 are not restricted, the elastic force of the two springs 13 can drive the two clamps 11 to move toward each other, so as to clamp the battery pack. Baffles 12 are fixed at the other ends of the two cross bars 10, and the baffles 12 can be used to block the other ends of the two cross bars 10 to prevent the two cross bars 10 from falling off the protective cover 5. At the same time, the movement of the two cross bars 10 can be limited by restricting the two baffles 12.

[0038] On the basis of the above structure, two slides 14 are fixed on both sides of the protective cover 5, and the four slides 14 are respectively located on the upper and lower sides of the two cross bars 10. The four slides 14 are slidably sleeved with limiting members 15, and the four limiting members 15 respectively abut against one side of the two baffles 12. The four limiting members 15 can slide on the four slides 14. When the two clamps 11 do not clamp the battery pack, the two baffles 12 can be pulled and the four limiting members 15 can be slid so that one end of the four limiting members 15 abuts against one side of the two baffles 12 to limit the two baffles 12. The movement of the two clamps 11 can be limited so that the two clamps 11 no longer clamp the battery pack.
