[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a multifunctional portable energy system for polymer lithium-ion batteries, including a housing 1, a polymer lithium-ion battery pack 2 installed inside the housing 1, a storage slot 3 on the housing 1, and a connecting component installed inside the storage slot 3;

[0025] The connecting assembly includes a damping shaft 4 fixedly connected to the storage groove 3. A sleeve 5 is rotatably sleeved on the damping shaft 4. A connecting plate 6 is fixedly connected to the outer wall of the sleeve 5. A stud 7 is fixedly connected to the connecting plate 6. A U-shaped plate 8 is threaded onto the stud 7. A threaded hole 25 is opened on the U-shaped plate 8. The stud 7 passes through the threaded hole 25 through the U-shaped plate 8. Two shaft holes are symmetrically opened on the U-shaped plate 8, and an adjusting screw 9 is rotatably sleeved in the shaft holes. Two collets 10 are symmetrically threaded onto the adjusting screw 9. Both collets 10 have threaded holes with opposite thread directions. The adjusting screw 9 passes through the collets 10 through the threaded holes. A connector 11 is fixedly connected to the U-shaped plate 8. A flexible wire 12 is fixedly connected between the connector 11 and the polymer lithium-ion battery pack 2.

[0026] In the above embodiments, when the polymer lithium-ion battery needs to be carried, the connecting plate 6 is moved, causing the sleeve 5 to rotate on the damping shaft 4, thereby rotating the connecting component into the storage slot 3 for storage. This allows the connecting component to be folded into the housing 1, reducing the space occupied by the polymer lithium-ion battery energy system when carried. When needed, the connecting plate 6 is moved to rotate the connecting component out of the storage slot 3, allowing the energy system to be quickly unfolded. The tilt angle of the two clamps 10 can be adjusted according to actual usage requirements to adapt to different installation needs. By twisting the U-shaped plate 8 to disengage it from the stud 7, different clamps 10 can be quickly replaced, effectively improving the flexibility and convenience of the energy system. The polymer lithium-ion battery energy system can be quickly folded and unfolded, effectively reducing the space occupied by the polymer lithium-ion battery energy system when carried and effectively improving the convenience of carrying the polymer lithium-ion battery energy system.

[0027] The housing 1 has an installation groove 13, and a sealing plate 14 is slidably connected in the installation groove 13. The sealing plate 14 and the housing 1 are both fixedly connected with semi-circular threaded posts 15. Two semi-circular threaded posts 15 form a threaded post, and the two semi-circular threaded posts 15 are externally threaded with the same locking internal threaded cylinder 16.

[0028] In this embodiment, when the polymer lithium-ion battery pack 2 needs to be replaced, the locking internal threaded cylinder 16 is screwed on. Through the threaded engagement between the locking internal threaded cylinder 16 and the semi-circular threaded post 15, the locking internal threaded cylinder 16 is disengaged from the two semi-circular threaded posts 15, thereby releasing the locking internal threaded cylinder 16 from limiting and fixing the sealing plate 14. The sealing plate 14 is then pulled to disengage from the mounting groove 13, releasing the sealing plate 14 from limiting the polymer lithium-ion battery pack 2. The polymer lithium-ion battery pack 2 is then removed from the housing 1 and replaced with a new polymer lithium-ion battery pack 2. The sealing plate 14 is reinserted into the mounting groove 13, and the locking internal threaded cylinder 16 is screwed onto the two semi-circular threaded posts 15, completing the quick replacement of the polymer lithium-ion battery pack 2. The operation is simple and convenient, effectively improving the battery swapping efficiency and convenience of the polymer lithium-ion battery energy system.

[0029] One end of the adjusting screw 9 is fixedly connected to a rotating plate 17. The rotating plate 17 has a threaded pin hole 18. A locking bolt 19 is threaded into the threaded pin hole 18. By tightening the locking bolt 19, the adjusting screw 9 can be limited and locked, thereby preventing the adjusting screw 9 from rotating on its own.

[0030] Two guide rails 20 are symmetrically fixedly connected to the sealing plate 14, and two guide rail grooves 21 are symmetrically opened on the mounting groove 13. The two guide rails 20 are respectively located in the two guide rail grooves 21. The stability of the sealing plate 14 can be improved by the cooperation between the guide rails 20 and the guide rail grooves 21.

[0031] The outer wall of the locking internal thread cylinder 16 is symmetrically fixedly connected with a butterfly-shaped rotating plate 22, which improves the convenience of rotating the locking internal thread cylinder 16.

[0032] The chuck 10 fits tightly against the inner side of the U-shaped plate 8, which can prevent the chuck 10 from rotating and improve the stability of the movement of the chuck 10.

[0033] A quick connector 23 is fixedly connected between the connector 11 and the flexible wire 12, which can improve the convenience of connecting and disconnecting the polymer lithium-ion battery pack 2 and the connector 11.

[0034] The locking bolt 19 is fixedly connected to an operating lever 24 at the end away from the U-shaped plate 8, which can improve the convenience of rotating the locking bolt 19.

[0035] Working principle: When the polymer lithium-ion battery needs to be carried, the connecting plate 6 is moved, and the connecting plate 6 drives the sleeve 5 to rotate on the damping shaft 4, thereby rotating the connecting component into the storage slot 3 for storage. This allows the connecting component to be folded into the housing 1, reducing the space occupied by the polymer lithium-ion battery energy system when carried. When needed, the connecting plate 6 is moved to rotate the connecting component out of the storage slot 3, allowing the energy system to be quickly unfolded. The tilt angle of the two clamps 10 can be adjusted according to actual usage needs to adapt to different installation requirements. By twisting the U-shaped plate 8 to disengage it from the stud 7, different clamps 10 can be quickly replaced, effectively improving the flexibility and convenience of the energy system. The polymer lithium-ion battery energy system can be quickly folded and unfolded, effectively reducing the space occupied by the polymer lithium-ion battery energy system when carried and effectively improving the convenience of carrying the polymer lithium-ion battery energy system.

[0036] When the polymer lithium-ion battery pack 2 needs to be replaced, tighten the locking internal threaded cylinder 16. Through the threaded engagement between the locking internal threaded cylinder 16 and the semi-circular threaded post 15, the locking internal threaded cylinder 16 is disengaged from the two semi-circular threaded posts 15, thereby releasing the locking internal threaded cylinder 16 from limiting and fixing the sealing plate 14. Pull the sealing plate 14 to disengage it from the mounting groove 13, releasing the sealing plate 14 from limiting the polymer lithium-ion battery pack 2. Remove the polymer lithium-ion battery pack 2 from the housing 1 and replace it with a new polymer lithium-ion battery pack 2. Reinsert the sealing plate 14 into the mounting groove 13 and tighten the locking internal threaded cylinder 16 onto the two semi-circular threaded posts 15 to complete the quick replacement of the polymer lithium-ion battery pack 2. The operation is simple and convenient, effectively improving the battery swapping efficiency and convenience of the polymer lithium-ion battery energy system.
