[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: When using existing lithium-ion battery packs, multiple lithium-ion battery packs often need to be connected by wires to enable them to output sufficient current and voltage to the electrical equipment. During connection, the wires are connected through the wiring ports of the lithium-ion battery packs, and the wires extend along the outer surface of the lithium-ion battery packs to connect to the wiring ports of other lithium-ion battery packs. After connection, there are many exposed wires, which makes wire management inconvenient. At the same time, the wires are easily damaged by friction when handling lithium-ion battery packs, resulting in poor safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a safe and convenient lithium-ion battery pack that is easy to manage and whose wires are not easily worn.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safe and convenient lithium-ion battery pack, including a battery body, a cover fixedly installed on the end of the battery body, a cavity formed between the inner wall of the cover and the end surface of the battery body, a first interface provided at the end of the battery body on the inner wall of the cavity, a first slot integrally formed on the cover at the corresponding position of the first interface, a first cover plate detachably provided at the edge of the first slot, and a wire outlet block detachably and snap-fit ​​on the cover.

[0006] A further improvement is that a second interface is provided at the end of the battery body located on the inner wall of the cavity, and a second slot is integrally formed on the cover at the corresponding position of the second interface, with a second cover plate detachably provided at the edge of the second slot.

[0007] A further improvement is that a circuit breaker is provided on the end of the battery body located on the side of the second interface, and the second cover plate is integrally formed with a circuit breaker opening at the corresponding position of the circuit breaker.

[0008] A further improvement is that the cable outlet block includes a fixing block that can be detachably fastened to the cover and a cover sheet that is fixedly disposed on the inner wall of the fixing block. The cover sheet has an integrally formed cross-shaped cable outlet groove that penetrates the cover sheet.

[0009] A further improvement is that the edge of the fixing block is integrally formed with a snap-fit ​​groove.

[0010] A further improvement is that a control panel is fixedly installed on the front of the battery body.

[0011] A further improvement is that a lifting groove is provided on the side wall of the battery body.

[0012] A further improvement is that the first cover plate has several ventilation holes integrally formed.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model provides a cover on the end of the battery body, and provides a first slot and a second slot on the cover, so that the wire can be inserted into the first interface and the second interface through the first slot and the second slot, and the wire is routed in the cavity formed by the cover and the battery body. Then the end of the wire is passed out from the wire outlet slot of the wire outlet block. After the wiring is completed, the first cover plate and the second cover plate are covered, so that only the part of the wire that passes out of the wire outlet block is exposed, and the rest is covered by the cover. During transportation, the wire is less likely to be damaged by friction, which is safer. At the same time, since the wires all pass out of the wire outlet block, the wiring between multiple battery packs is more orderly and the wiring is easier to manage when connecting multiple battery packs.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See Figure 1-5 As shown, the technical solution adopted in this specific embodiment is as follows: a safe and convenient lithium-ion battery pack includes a battery body 1, a cover 11 fixedly installed on the end of the battery body 1, a cavity 15 formed between the inner wall of the cover 11 and the end surface of the battery body 1, a first interface 16 provided at the end of the battery body 1 on the inner wall of the cavity 15, a first slot integrally formed on the cover 11 at the corresponding position of the first interface 16, a first cover plate 3 detachably provided at the edge of the first slot, and a wire outlet block 4 detachably and snap-fitted on the cover 11. The wire outlet block 4 includes a fixing block 41 detachably snap-fitted on the cover 11 and a cover plate 43 fixedly disposed on the inner wall of the fixing block 41. A cross-shaped wire outlet groove 44 penetrating the cover plate 43 is integrally formed on the cover plate 43. In use, multiple lithium batteries are loaded together to form the battery body 1, and the cover 11 is installed on the end of the battery body 1. The cavity 15 formed between the cover 11 and the end of the battery body 1 allows the wiring to... The wires are threaded through the cavity 15, which has a certain height equal to or greater than the width of five standard wires, allowing them to pass through fully. Then, the external wires are inserted into the cavity 15 through the first slot on the cover 11 and connected to the first interface 16 at the end of the battery body 1. The wires are then wound into the cavity 15, with the other end exiting through the outlet slot 44 formed on the cover plate 43 of the outlet block 4. The outlet block 4 is made of a highly elastic material, such as silicone or rubber, which is not too hard and will not scratch or wear the outer surface of the wires. The first cover plate 3 is then bolted in to cover and conceal the first slot, ensuring that only the portion of the wire exiting through the outlet block 4 is exposed, while the rest is covered by the cover 11. This prevents damage during transportation and enhances safety. Since all wires exit through the outlet block 4, the wiring between multiple battery packs is more organized and easier to manage when connecting multiple battery packs.

[0022] The battery body 1 is provided with a second interface 12 at the end of the cavity. The cover 11 is integrally formed with a second slot at the corresponding position of the second interface 12. The edge of the second slot is provided with a second cover plate 2, which is convenient to connect more external wires through the second interface 12. When connecting, the wires are connected through the second slot, and after connecting the wires to the second interface 12, they are wound into the cavity 15 and protrude from the protruding block 4. This allows the battery pack to connect more lines without affecting the protection of the wires and the convenience of wire management.

[0023] A circuit breaker 13 is provided on one side of the second interface 12 at the end of the battery body 1. The second cover plate 2 is integrally formed with a circuit breaker opening 21 at the corresponding position of the circuit breaker 13. This facilitates the rapid disconnection of current when the battery body 1 is not operating normally through the circuit breaker 13. The circuit breaker opening 21 on the second cover plate 2 allows the circuit breaker 13 to be used quickly without removing the second cover plate 2. This makes the response more rapid in emergency situations and makes the use of the battery pack safer.

[0024] The edge of the fixing block 41 is also integrally formed with a snap-fit ​​groove 42, which helps the fixing block 41 to be better snapped and fixed to the cover 11.

[0025] A control panel 6 is fixedly installed on the front of the battery body 1. The control panel 6 is existing technology and is convenient for monitoring the battery body 1 and observing its status through the control panel 6.

[0026] The battery body 1 has a lifting groove 5 on its side wall, which makes it easier and more convenient to carry the battery pack by reaching into the lifting groove 5 to lift it up.

[0027] The first cover plate 3 has several vent holes integrally formed, which helps to dissipate the heat generated inside the first cover plate 3 and prevent the connection end from getting too hot.

[0028] The working principle of this utility model is as follows: When using this utility model, multiple lithium batteries are loaded together to form a battery body 1, and a cover 11 is installed on the end of the battery body 1. A cavity 15 is formed between the cover 11 and the end of the battery body 1, allowing the wires to pass through the cavity 15. Then, the external wires can be inserted into the cavity 15 through the first slot on the cover 11 and connected to the first interface 16 at the end of the battery body 1. The wires are then wound into the cavity 15, and the other end of the wires passes through the outlet slot 44 formed on the cover plate 43 of the outlet block 4. The first cover plate 3 is then bolted in to cover and conceal the first slot. This ensures that only the part of the wire that passes through the outlet block 4 is exposed, while the rest is covered by the cover 11. This makes it less likely for the wires to be damaged by friction during transportation, thus improving safety. At the same time, since the wires all pass through the outlet block 4, the wiring is more organized and easier to manage when connecting multiple battery packs.
