The negative nickel sheet 203 is electrically connected to the positive nickel sheet 205 through a protection board assembly. The positive nickel sheet 201 and the negative nickel sheet 207 are both electrically connected to the plug head 1 through a protection board assembly;

[0050] Working principle of the above technical solution: Insert the battery cell group 401 into the battery cell support 3. The positive nickel sheet 201 and multiple series nickel sheets 202 are welded to one end of the battery cell group 401. The negative nickel sheet 203 and multiple series nickel sheets 204 are welded to the other end of the battery cell group 401.

The material of the EVA auxiliary support 6 is ethylene-vinyl acetate copolymer, which has a certain elasticity and prevents the battery cell group one 401 and the battery cell group two 402 from colliding under vibration, having a certain shock-absorbing effect.

[0056] Embodiment Five

[0057] As Figures 1 - 14 shown, the battery cell support one 3 includes a frame one 301. The frame one 301 is fixed to the lower end of the protection board assembly through a lock plate screw 9.

[0058] The battery cell support two 7 includes a frame two 701. The frame two 701 is fixed to the lower end of the protection board assembly through a lock plate screw 9. A plurality of battery cell insertion tubes two 702 are provided inside the frame two 701, and the battery cell group two 402 is inserted into the battery cell insertion tubes two 702. A connection insertion tube 703 and a card slot 704 are provided at the end of the frame two 701. The insertion rod 303 is inserted into the connection insertion tube 703, and the buckle two 304 is clamped in the card slot 704;

[0059] Working principle of the above technical solution: The first battery cell group 401 includes multiple battery cells. The multiple battery cells are respectively inserted into multiple first battery cell insertion tubes 302. The second battery cell group 402 also includes multiple battery cells. The multiple battery cells are respectively inserted into multiple second battery cell insertion tubes 702. The second positive nickel sheet 205 and multiple series-connected third nickel sheets 206 are both welded to one end of the second battery cell group 402. The first negative nickel sheet 203 and multiple series-connected second nickel sheets 204 are both welded to the other end of the first battery cell group 401, thereby completing the assembly of the first battery cell assembly. The second positive nickel sheet 205 and multiple series-connected third nickel sheets 206 are both welded to one end of the second battery cell group 402. The second negative nickel sheet 207 and multiple series-connected fourth nickel sheets 208 are both welded to the other end of the second battery cell group 402, thereby completing the assembly of the second battery cell assembly.

The insertion rod 303 on the first battery cell assembly is inserted into the connection insertion tube 703 on the second battery cell assembly. The second buckle 304 on the first battery cell assembly is snapped into the slot 704 on the second battery cell assembly, thereby completing the preliminary installation between the first battery cell assembly and the second battery cell assembly. Then, the first battery cell assembly and the second battery cell assembly are fixed to the lower end of the protection board assembly through the lock plate screw 9, further increasing the stability among the first battery cell assembly, the second battery cell assembly, and the protection board assembly, and preventing the first battery cell assembly and the second battery cell assembly from loosening after long-term use.

[0060] Example Six

[0061] As Figures 1 - 14 shown, the first battery cell insertion tube 302 includes an insertion tube 3021. The insertion tube 3021 is fixed in the first frame 301. Four adjusting screws 3022 are threadedly connected to the end of the insertion tube 3021. One end of each adjusting screw 3022 is fixedly connected to a limiting rod 3023. The other end of the limiting rod 3023 is slidably engaged in a vertical groove 3025 at the end of an elastic metal sheet 3024. The elastic metal sheet 3024 slides in an inclined groove 3026 inside the insertion tube 3021;

[0062] Working principle of the above technical solution: The battery cells in the first battery cell group 401 are inserted into the insertion tube 3021. The battery cells squeeze the four elastic metal sheets 3024 to expand outwards, and the four elastic metal sheets 3024 clamp the battery cells.

[0063] By providing the elastic metal sheets 3024, battery cells of different thickness models can be clamped in the insertion tube 3021, with strong adaptability; when vibration occurs, the elastic metal sheets 3024 can deform, having a certain shock-absorbing effect, effectively protecting the battery cells from being damaged by vibration; the elastic metal sheets 3024 can keep a certain gap between the battery cells and the insertion tube 3021, enabling the battery cells to have a heat dissipation space and preventing their temperature from being too high;

[0064] After being used for a period of time, the elastic metal sheet 3024 will lose some of its elasticity, and the clamping force on the battery cell will be weakened. Use tools such as a screwdriver to turn the adjusting screw 3022 so that the adjusting screw 3022 moves into the insertion tube 3021. The adjusting screw 3022 drives the elastic metal sheet 3024 to slide in the inclined groove 3026 through the limiting rod 3023. Due to the action of the inclined groove 3026, the four elastic metal sheets 3024 move closer together. The limiting rod 3023 slides in the vertical groove 3025. After the four elastic metal sheets 3024 move closer together, the clamping force on the battery cell is increased, and the service life of the battery cell insertion tube 3021 is extended. In addition, the adjusting screw 3022 is arranged at one end of the insertion tube 3021 and serves as an indication mark to indicate the insertion direction of the battery cell.

On one side of the second chute 55, there are a fourth positive terminal 35, a fifth positive terminal 36, and a sixth positive terminal 37. On the other side of the second chute 55, there are a fourth negative terminal 38, a fifth negative terminal 39, and a sixth negative terminal 40. In the initial state, the middle of the fourth positive terminal 35 is clamped within the second positive metal sheet 33, and the second negative metal sheet 34 is clamped within the second negative metal sheet 34. Both the fourth positive terminal 35 and the sixth positive terminal 37 are electrically connected to the first positive nickel sheet 201 through a sixth wire 42. The fifth positive terminal 36 is electrically connected to the second positive nickel sheet 205 through a fifth wire 41. Both the fourth negative terminal 38 and the fifth negative terminal 39 are electrically connected to the second negative nickel sheet 207 through a seventh wire 43. The sixth negative terminal 40 is electrically connected to the first negative nickel sheet 203 through an eighth wire 44. A third metal strip 49 and a fourth metal strip 50 are fixedly arranged in parallel on the chassis 17. The upper end of the second positive metal sheet 33 is slidably connected to the third metal strip 49, and the upper end of the second negative metal sheet 34 is slidably connected to the fourth metal strip 50. The third metal strip 49 is electrically connected to the charging socket 53 through an eleventh wire 51, and the fourth metal strip 50 is electrically connected to the charging socket 53 through a twelfth wire 52. The charging socket 53 is fixed on the chassis 17;

[0069] A cover plate 15 is buckled on the chassis 17. A slide button 14 is inserted into the power supply adjustment slider 18. The slide button 14 slides on the cover plate 15. There are three groups of marking lines 16 on the cover plate 15. The upper end of the charging socket 53 is located on the cover plate 15. There are two long holes on the upper shell 12, and the slide button 14 and the charging socket 53 can be operated respectively through the two long holes;

[0070] Working principle of the above technical solution: In the initial state, the positive metal sheet 19 on the power supply adjustment slider 18 is connected to the positive nickel sheet 201 through the first positive terminal 21 and the first wire 27. The negative metal sheet 20 on the power supply adjustment slider 18 is connected to the second negative nickel sheet 207 through the first negative terminal 24 and the third wire 29. Since the first negative nickel sheet 203 and the second positive nickel sheet 205 are electrically connected through the protection board 8, when the plug head 1 is connected to the power supply device, the first battery cell group 401 and the second battery cell group 402 are connected in series for power supply; the positive metal sheet 33 on the charging adjustment slider 32 is connected to the positive nickel sheet 201 through the fourth positive terminal 35 and the sixth wire 42. The negative metal sheet 34 on the charging adjustment slider 32 is connected to the second negative nickel sheet 207 through the fourth negative terminal 38 and the seventh wire 43. When an external power supply is plugged into the charging socket 53, the series-connected first battery cell group 401 and the second battery cell group 40 can be charged. The first battery cell group 401 and the second battery cell group 40 are connected in series for power supply, which has the advantage of longer power supply time. However, like traditional rechargeable batteries, they can only supply power or charge separately and cannot supply power and charge simultaneously. As a result, when this special-shaped battery structure is charging, the power supply device cannot be used;

[0071] Push the sliding button 14. The sliding button 14 slides on the cover plate 15, driving the power supply adjustment slider 18 to slide to the middle position in the first chute 54. The first positive metal sheet 19 is separated from the first positive terminal 21, and the first negative metal sheet 20 is separated from the first negative terminal 24. After the power supply adjustment slider 18 moves in place in the first chute 54, the first positive metal sheet 19 is clamped with the second positive terminal 22, and the first negative metal sheet 20 is clamped with the second negative terminal 25. The first positive metal sheet 19 on the power supply adjustment slider 18 is connected to the first positive nickel sheet 201 through the second positive terminal 22 and the first wire 27. The first negative metal sheet 20 on the power supply adjustment slider 18 is connected to the first negative nickel sheet 203 through the second negative terminal 25 and the fourth wire 30. When the plug head 1 is connected to the power supply device, power is supplied separately through the first battery cell group 401; while the power supply adjustment slider 18 slides in the first chute 54, the middle part of the rotating rod 31 driven by the power supply adjustment slider 18 rotates with the chassis 17. The rotating rod 31 drives the charging adjustment slider 32 to slide to the middle position in the second chute 55. The second positive metal sheet 33 is separated from the fourth positive terminal 35, and the second negative metal sheet 34 is separated from the fourth negative terminal 38. After the charging adjustment slider 32 moves in place in the second chute 55, the second positive metal sheet 33 is clamped with the fifth positive terminal 36, and the second negative metal sheet 34 is clamped with the fifth negative terminal 39. The second positive metal sheet 33 on the charging adjustment slider 32 is connected to the second positive nickel sheet 205 through the fifth positive terminal 36 and the fifth wire 41. The second negative metal sheet 34 on the charging adjustment slider 32 is connected to the second negative nickel sheet 207 through the fifth negative terminal 39 and the seventh wire 43. When an external power supply is plugged into the charging socket 53, the second battery cell group 402 can be charged separately. That is, the first battery cell group 401 supplies power to the power supply device, and the external power supply charges the second battery cell group 402. Charging and discharging do not conflict;

[0072] When the power in the battery cell group 401 is exhausted and the battery cell group 402 is fully charged, continue to push the sliding button 14 downward, so that the power supply adjustment slider 18 slides to the bottom end in the first chute 54. The first positive metal sheet 19 is separated from the second positive terminal 22, and the first negative metal sheet 20 is separated from the second negative terminal 25. After the power supply adjustment slider 18 moves in place in the first chute 54, the first positive metal sheet 19 is clamped with the third positive terminal 23, and the first negative metal sheet 20 is clamped with the third negative terminal 26. The first positive metal sheet 19 on the power supply adjustment slider 18 is connected to the second positive nickel sheet 205 through the third positive terminal 23 and the second wire 28. The first negative metal sheet 20 on the power supply adjustment slider 18 is connected to the second negative nickel sheet 207 through the third negative terminal 26 and the third wire 29. When the plug head 1 is connected to the power supply device, the fully charged battery cell group 402 supplies power alone. While the power supply adjustment slider 18 slides in the first chute 54, the middle of the rotating rod 31 driven by the power supply adjustment slider 18 rotates with the chassis 17. The rotating rod 31 drives the charging adjustment slider 32 to slide to the upper end of the second chute 55. The second positive metal sheet 33 is separated from the fifth positive terminal 36, and the second negative metal sheet 34 is separated from the fifth negative terminal 39. After the charging adjustment slider 32 moves in place in the second chute 55, the second positive metal sheet 33 is clamped with the sixth positive terminal 37, and the second negative metal sheet 34 is clamped with the sixth negative terminal 40. The second positive metal sheet 33 on the charging adjustment slider 32 is connected to the first positive nickel sheet 201 through the sixth positive terminal 37 and the sixth wire 42. The second negative metal sheet 34 on the charging adjustment slider 32 is connected to the first negative nickel sheet 203 through the sixth negative terminal 40 and the eighth wire 44. When the external power supply is plugged into the charging socket 53, the battery cell group 401 with exhausted power can be charged alone. By sliding the sliding button 14 up and down, the series power supply or individual power supply state of the battery cell group 401 and the battery cell group 402 can be adjusted. In the case of series power supply, it has the advantages of concentrated energy, large output power, and long power supply time. In the case of individual power supply, the battery cell group 401 and the battery cell group 402 can supply power and charge alternately to keep the power supply device always powered. In addition, it is not necessary to disconnect the special-shaped battery structure from the power supply device for charging. The special-shaped battery structure and the power supply device can maintain a long connection, and the charging socket 53 and the external power supply can maintain a long connection. Only the sliding button 14 needs to be operated, which is convenient and fast;

[0073] The middle of the first positive terminal 21 is recessed into the first positive metal sheet 19, which can increase the contact area between the two and prevent virtual connection between the two. The first positive terminal 21 has a certain elasticity, so that when the power supply adjustment slider 18 moves in the first chute 54, it can be clamped at the preset position to maintain the accuracy of movement;

[0074] One end of the first positive terminal 21 and the end of the first wire 27 are both fixed on the first chute 54 through a set of screws, with a simple structure and reduced manufacturing cost;

[0075] The upper end of the first positive metal sheet 19 is electrically transmitted through a sliding connection with the second metal strip 46, reducing direct wire connection and the occurrence of wire twisting and breaking.

[0076] There are three groups of identification lines 16 provided on the cover plate 15, and the three groups of identification lines 16 respectively correspond to the power supply methods, facilitating the operator to view and operate.
