[0030] Please see Figures 1-10 This utility model provides a technical solution:

[0031] A modular small lithium battery includes a battery body 1 and a heat-conducting sleeve 2. The heat-conducting sleeve 2 is fixed to the outside of the battery body 1. The heat-conducting sleeve 2 has snap-fit ​​grooves 3 on both the upper and lower sides of its four longitudinal planes. Each snap-fit ​​groove 3 includes openings 31 at the upper and lower ends of the heat-conducting sleeve 2. A semi-circular groove 32 is formed on the side of the opening 31 away from the upper and lower ends of the heat-conducting sleeve 2. A snap-fit ​​annular channel 33 is formed on the outer side of the semi-circular groove 32. A positioning slot 34 is formed on the side of the semi-circular groove 32 away from the opening 31. The inner side of each groove 3 is equipped with a connecting block 4. The connecting block 4 includes a semi-circular block 41 located inside the semi-circular groove 32. The outer side of the semi-circular block 41 is fixedly connected to a connecting rail 42 that is slidably connected to the connecting ring track 33. The inner side of the connecting rail 42 is provided with a rail groove 43 that is vertically aligned with the positioning slot 34. A recessed groove 44 is provided on the side of the rail groove 43 near the battery body 1. A damping pad 45 is fixedly connected to the inner side of the recessed groove 44. A transmission positioning component 5 is slidably connected to the inner side of the rail groove 43.

[0032] The inner diameter of the semicircular groove 32 is the same as the diameter of the semicircular block 41. The outer curved surface of the semicircular block 41 fits into the inner curved surface of the semicircular groove 32. This arrangement allows the semicircular block 41 to rotate stably within the semicircular groove 32. The rectangular plane of the semicircular block 41 is aligned with the longitudinal plane of the heat-conducting sleeve 2. This arrangement allows the semicircular blocks 41 of batteries A and B to be simultaneously spliced ​​and fitted when the heat-conducting sleeves 2 of batteries A and B are joined together. (The last sentence appears to be unrelated and refers to a locking ring 3.) 3 is a T-shaped channel structure. The cross-section of the locking rail component 42 is T-shaped. This design prevents the locking rail component 42 from directly disengaging from the locking ring channel 33. The locking rail component 42 can only be rotated out of the locking ring channel 33. Both ends of the locking rail component 42 are rounded, allowing it to easily rotate into the locking ring channel 33 of another battery. The rail channel 43 consists of a central channel and rails on both sides. The transmission positioning component 5 is located at the top. The transmission positioning component 5 consists of a rotating block and a lower rail block. The lower rail block of the transmission positioning component 5 is composed of a middle block and rails on both sides. The rails of the transmission positioning component 5 are all set inside the rails on both sides of the rail groove 43. This setting allows the transmission positioning component 5 to slide at the adapter block 4. The upper rotating block of the transmission positioning component 5 is set at the opening 31. This setting allows the user to pass through the opening 31 to contact the upper rotating block of the transmission positioning component 5. The lower rail blocks of the transmission positioning component 5 are all inserted into the inner side of the positioning slot 34. The outer end face of the lower rail block of the transmission positioning component 5 is in contact with the inner wall of the positioning slot 34. This setting allows the transmission positioning component 5 to be normally inserted into the positioning slot 34 of the snap-fit ​​groove 3 so that it cannot rotate. It can position the adapter block 4 that is linked to it, so that the adapter block 4 cannot rotate on its own. The outer end face of the lower rail block of the transmission positioning component 5 is in contact with the damping pad 45. This setting prevents the transmission positioning component 5 from moving on its own due to the influence of the damping pad 45 of the adapter block 4.

[0033] Workflow: The assembly and splicing operation of the modular small lithium battery is as follows: The heat-conducting sleeve 2 can dissipate heat from the battery body 1 to the outside, and through the opening of the snap-fit ​​groove 3, it can support the adapter block 4 and the transmission positioning component 5. The snap-fit ​​groove 3 can also be used for the assembly and splicing between batteries. The transmission positioning component 5 is normally inserted into the positioning slot 34 of the snap-fit ​​groove 3 so that it cannot rotate. It can position the adapter block 4 connected to it, so that the adapter block 4 cannot rotate on its own. The transmission positioning component 5 is also unable to move on its own due to the damping pad 45 of the adapter block 4. This ensures that the positions of the adapter block 4 and the transmission positioning component 5 in the snap-fit ​​groove 3 remain unchanged. When it is necessary to connect with other batteries, the heat-conducting sleeves 2 of battery A and battery B are attached together. The process begins by engaging and fitting the adapter blocks 4 and transmission positioning parts 5 of A and B together, forming a complete circular adapter block 4 from the two semicircular adapter blocks 4 of A and B. Then, by squeezing the assembled transmission positioning part 5, it displaces the part from the positioning slot 34. The complete circular adapter block 4 can then be rotated 90 degrees by rotating the transmission positioning part 5, causing the semicircular block 41 and locking rail 42 of adapter block 4 of A to enter the semicircular groove 32 and locking ring 33 of adapter block 4 of B. Similarly, the semicircular block 41 and locking rail 42 of adapter block 4 of B are rotated into the semicircular groove 32 and locking ring 33 of adapter block 4 of A. This completes the connection between the two batteries, allowing for the flexible combination and assembly of small lithium batteries according to the user's needs.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
