Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0026] Please refer to Figures 1 to 9 , the present utility model provides a technical solution: a battery pack assembly structure, including a battery pack housing 1, a plurality of groups of batteries 2 are fixedly installed and connected inside the battery pack housing 1, and a plug-in board 3 for providing power is fixedly installed and connected to the upper surface of one side of the battery pack housing 1;

[0027] The upper surface of the battery pack housing 1 is symmetrically clamped and connected with a first half shell 6 and a second half shell 7. A through groove 8 is formed between the first half shell 6 and the second half shell 7. A set of rectangular half grooves 9 symmetrically clamped on both sides of the plug-in board 3 are arranged inside the first half shell 6 and the second half shell 7. A pressing member 4 is slidably connected inside one side surface of the battery pack housing 1. A plug-in board 5 is fixedly connected to one side of the pressing member 4. The specific shape of the plug-in board 5 is a door-shaped buckle. A clamping groove 21 for the plug-in board 5 to be clamped is jointly arranged on the lower surface of one side of the first half shell 6 and the second half shell 7. Inner sliding jacks 11, outer sliding jacks 12 and threaded inner grooves 121 are arranged inside and outside the first half shell 6 in a front-back distribution. Front sliding plugs 13 and rear sliding plugs 14 are respectively slidably inserted into the inner parts of the inner sliding jacks 11 and the outer sliding jacks 12, and the front sliding plugs 13 and the rear sliding plugs 14 are respectively fixedly connected to the inside and outside of the second half shell 7. One end of the rear sliding plug 14 is fixedly connected with a positioning bolt 19 threadedly positioned inside the threaded inner groove 121, and the other end of the rear sliding plug 14 is fixedly connected with a limiting disk 18. An activity groove 122 for the limiting disk 18 and the rear sliding plug 14 to slide is arranged inside one side of the second half shell 7. The limiting disk 18 is slidably limited inside the activity groove 122;

[0028] A set of symmetric limiting plates 10 are fixedly connected inside the first half shell 6 and the second half shell 7. The limiting plates 10 are located on both sides above the rectangular half grooves 9, and there is a gap between the limiting plates 10 and the plug-in board 3. The abutting connecting surface of the rectangular half grooves 9 is provided with an outward inclined surface 17.

[0029] More specifically, in this embodiment, the operator presses the pressing member 4, and the first half shell 6 and the second half shell 7 are respectively slidably clamped on both sides of the plug-in board 3 through the rectangular half grooves 9, so that the first half shell 6 and the second half shell 7 are relatively slid and inserted. When sliding and inserting, the front sliding plugs 13 and the rear sliding plugs 14 are slidably inserted into the inner parts of the inner sliding jacks 11 and the outer sliding jacks 12 to determine the assembly position. Subsequently, the pressing member 4 is released, and the plug-in board 5 is inserted into the clamping groove 21, so that the front parts of the first half shell 6 and the second half shell 7 are tightly buckled and a connection relationship with the battery pack housing 1 is established. Subsequently, the rear sliding plug 14 is rotated. The rear sliding plug 14 drives the limiting disk 18 and the positioning bolt 19 to rotate synchronously. The positioning bolt 19 rotates threadedly in the threaded inner groove 121 to achieve the purpose of locking and stabilizing. At the same time, the limiting disk 18 rotates in a limited manner in the activity groove 122 and abuts against the groove wall of the activity groove 122 to achieve the purpose of abutting and limiting, thereby preventing the sliding and detachment of the rear sliding plug 14, and further providing a front buckling and rear locking effect for the assembly of the first half shell 6 and the second half shell 7 to the battery pack housing 1, which not only ensures the tightness of the assembly between the first half shell 6 and the second half shell 7, but also ensures the stable effect of the assembly of the first half shell 6 and the second half shell 7 on the battery pack housing 1;

[0030] The operator inserts the electric tool at the upper end through the through groove 8 and into the plug-in board 3 to use it electrically;

[0031] When the first half shell 6 and the second half shell 7 are inserted and slid relative to each other, the limiting plate 10 slides above the insertion plate 3 to achieve the limiting purpose.

[0032] Furthermore, strip-shaped card slots 15 are formed in the connecting surfaces on both sides of the first half shell 6, and card strips 16 are slidably inserted into the strip-shaped card slots 15, and the card strips 16 are fixedly connected to the connecting surface of the second half shell 7.

[0033] It should be noted that during the relative sliding process of the first half shell 6 and the second half shell 7, the card strips 16 are slidably inserted into the strip-shaped card slots 15, which also provides a positioning basis for the assembly of the two.

[0034] Embodiment 2, on the basis of the above embodiment:

[0035] Furthermore, heat dissipation grooves 20 are formed in the symmetric surfaces of the first half shell 6 and the second half shell 7.

[0036] More specifically, in this embodiment, the heat dissipation grooves 20 dissipate the heat generated when the electric tool is inserted and used with the insertion plate 3 out of the battery pack, thereby improving the service life of the battery pack.

[0037] Furthermore, five sockets 22 are formed in the upper surface of the battery pack housing 1. The sockets 22 are the positive electrode, C, ID1, ID2, and negative electrode from left to right. Anti-fooling ribs 23 are formed in the upper surface of the battery pack housing 1 near the sockets 22, and anti-fooling grooves 24 are formed in the upper surface of the battery pack housing 1 near the sockets 22 and away from the anti-fooling ribs 23.

[0038] It should be noted that the operator will perform power-on insertion according to the corresponding five sockets 22 of the positive electrode, C, ID1, ID2, and negative electrode. During the insertion process, the anti-fooling ribs 23 can prevent misinsertion of different machines and cause the situation of burning the machine, while the anti-fooling grooves 24 can further avoid the misinsertion phenomenon of different chargers.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
