[0002] Outdoor portable lithium battery packs are portable energy storage devices that provide temporary power to outdoor equipment. Their core features are portability, high capacity, and compatibility with a variety of devices.

[0003] Essentially, it integrates multiple lithium battery cells together through a circuit protection board (BMS), and then combines them with a casing, charging port, and discharging interface to form an energy storage product that can solve the power needs in outdoor scenarios.

[0004] Currently, portable lithium battery charging devices are essential for some outdoor sports users. However, users often need to move around outdoors, so they either have to carry the device by hand or put it in a backpack. When carrying it by hand, users can only operate it with their other hand, which is quite restrictive. When putting it in a backpack, it is cumbersome and time-consuming to retrieve it again, making the operation of existing devices inconvenient outdoors. In view of this, we propose a portable outdoor lithium battery pack to solve the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a portable outdoor lithium battery pack.

Detailed Implementation

[0015] 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.

[0016] like Figures 1 to 4As shown, this utility model provides an outdoor portable lithium battery pack, including a main shell 1, a secondary shell 11 detachably connected to the outside of the main shell 1, a cavity formed between the main shell 1 and the secondary shell 11, a lithium battery pack body 12 disposed inside the cavity, a rubber handle 13 fixedly disposed on the top of the main shell 1, a rotating component 2 symmetrically rotated on the outside of the main shell 1, a hanging strap 21 fixedly disposed on the inner side of both rotating components 2, a fixing component 3 symmetrically fixed on the outside of the main shell 1, a polyester strap A31 or a polyester strap B33 respectively fixedly disposed on the inner side of both fixing components 3, the polyester strap A31 and the polyester strap B33 are detachably disposed, and a sponge sleeve 22 is disposed on the outside of the hanging strap 21.

[0017] The main and secondary housings work together to provide physical protection for the battery, preventing outdoor collisions and dust from directly contacting the battery. The symmetrically rotating component 2 on the outer side of the main housing 1 can rotate freely around its own axis. The hanging strap 21 fixed on its inner side adjusts its angle with the rotating component 2, making it easy for users to hang the device on their backs. The sponge sleeve 22 on the outer side of the hanging strap 21 makes contact with the human body through its softness, reducing the pain when carrying the device. At the same time, the polyester straps A31 and B33 on the outer side of the main housing 1 can be detached and used together to provide secondary fixation for the attached device, improving the stability when using the device. The rubber grip 13 fixed on the top of the main housing 1 provides a stable grip point for the user, making it easy to operate the mobile device. The combination of the hanging strap 21 and the polyester straps ensures the stability of the device when hanging on the back, adapting to different mobile scenarios such as outdoor hiking and camping, improving the flexibility of use. At the same time, the detachable design of the polyester straps A31 and B33 facilitates the efficiency of fixing or untying the battery pack in outdoor scenarios.

[0018] like Figure 1 and Figure 2 As shown, the outer side of polyester tape A31 is provided with hook and loop fastener 32, and the outer side of polyester tape B33 is provided with textile adhesive 34. The hook and loop fastener 32 and textile adhesive 34 are attached together.

[0019] The Velcro 32 on the outside of polyester tape A31 comes into contact with the textile adhesive 34 on the outside of polyester tape B33 to form an adhesive fixation. When disassembly is required, pull polyester tape A31 and polyester tape B33 to the sides to separate them and complete the disassembly. Through the adhesive cooperation of Velcro 32 and textile adhesive 34, the connection and disassembly of polyester tapes can be quickly realized, improving the efficiency of fixing or unbinding battery packs in outdoor scenarios.

[0020] like Figure 1 and Figure 2 As shown, a fixing plate 4 is symmetrically fixed on the outer side of the main housing 1, and a number of cable management tubes 41 are fixed on the outer side of the fixing plate 4 for cable management. The number and size of the cable management tubes 41 on both sides are different, and the corresponding connection panel of the sub-housing 11 is used to accommodate different connecting wires.

[0021] When the lithium battery pack is connected to an external device, the connecting wires can pass through the inside of the cable tie tube 41. The cable tie tube 41 limits the wires through its wall, preventing them from getting tangled. At the same time, cable tie tubes of different sizes can pass through connecting wires of corresponding specifications. The different numbers of cable tie tubes 41 on both sides can adapt to the distribution of the connecting panel of the housing 11. Through the differentiated design of the number and size of the cable tie tubes 41, it can accommodate different currents and different numbers of external wires, while avoiding poor contact and wire crushing and damage caused by mixing wires of different specifications, thus ensuring electrical safety.

[0022] like Figure 4 As shown, an abutment plate 5 is fixedly provided on the outside of the main housing 1, and the side of the abutment plate 5 away from the main housing 1 is set at an inclined angle.

[0023] When in use, the inclined surface of the abutment plate 5 fits against the front of the human body, located at the abdomen. By increasing the contact area, the weight pressure of the battery pack is distributed. The inclined surface can improve the fit between the battery pack and the human body or the surface on which it is placed, reduce local pressure concentration, and enhance the stability and comfort of outdoor use.

[0024] like Figure 4 As shown, a positioning plate 6 is fixedly provided on the outside of the main housing 1, located above the abutment plate 5. An L-shaped connecting plate 61 is fixedly provided on the outside of the positioning plate 6. An open slot is formed between the positioning plate 6 and the L-shaped connecting plate 61 for storing the hanging strap 21, polyester strap A31 and polyester strap B33.

[0025] When not in use, the hanging strap 21, polyester strap A31, and polyester strap B33 can be folded and placed into the open slot for binding and fixing. The slot, through the limiting effect of the positioning plate 6 and the L-shaped connecting plate 61, prevents the straps from shaking freely. The open slot realizes the storage function of the hanging strap 21, polyester strap A31, and polyester strap B33, avoiding the idle straps from getting caught on tree branches and weeds outdoors, while keeping the battery pack's appearance clean, reducing strap wear, and extending the service life of accessories.

[0026] Working principle and usage process of this utility model: When in use, the device is first hung behind the user's neck via the strap 21, positioning it in front of the user. The sponge sleeve 22 on the outside of the strap 21, with its soft properties, comes into contact with the body, reducing the pain caused by carrying the device. Meanwhile, the polyester straps A31 and B33 on the outside of the main housing 1 are detachable and work together to provide secondary fixation for the device, improving stability during use. The rubber grip 13 fixed to the top of the main housing 1 provides a stable grip point for the user, facilitating the operation of the mobile device.
