Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery casing and a battery. Background Technology

[0002] The installation of a laptop battery in its battery compartment usually relies on the locking lugs on the battery casing (usually a plastic shell) and the screw posts inside the battery compartment to be connected by screws. This requires the position of the battery locking lugs to match the position of the screw posts inside the battery compartment.

[0003] However, with the rapid iteration of laptop products, the positions of the screw posts inside the battery compartment change. Since the locking lugs and plastic casing of traditional batteries are usually an inseparable unit formed using injection molding, the position of the locking lugs cannot be adjusted, making previous generation batteries incompatible with new generation laptops. This contradiction forces battery suppliers to redevelop matching battery casing molds for each generation of laptops with changes in the battery compartment structure and to complete injection molding process verification. This process significantly extends the project development cycle and substantially increases costs due to repeated investment in molds, consumption of testing resources, and management of multiple battery versions in inventory.

The snap-fit ​​protrusion 24 can be snapped into the slot 14 to restrict the first side 21 from protruding from the slot 13. Thus, by using the cooperation of the slot 14 and the snap-fit ​​protrusion 24, the adapter 2 is snapped into the slot 13 of the frame.

[0032] In this embodiment, preferably, the side wall of the slot 13 is provided with a plurality of slots 14, which are spaced apart along the length of the frame. The first side 21 is also provided with a plurality of snap-fit ​​protrusions 24. When the first side 21 is inserted into the slot 13, the plurality of snap-fit ​​protrusions 24 can be snapped into the slots 14 one by one, thereby improving the installation stability of the adapter 2 on the frame.

[0033] In this embodiment, preferably, as follows: Figures 2 to 4 As shown, the frame includes a third side 11 and a fourth side 12. The third side 11 and the fourth side 12 are spaced apart from each other along the thickness direction of the frame. The third side 11 is located on the side of the frame facing the inside of the outer shell body 1, and the fourth side 12 is located on the side of the frame facing the outside of the outer shell body 1. The gap between the third side 11 and the fourth side 12 forms the aforementioned slot 13 for the insertion of the first side 21 of the adapter 2. A slot 14 for engaging with the engaging protrusion 24 on the first side 21 is formed on the third side 11.

[0034] In this embodiment, preferably, as follows: Figures 2 to 4 As shown, the adapter 2 also includes a second side portion 22. The first side portion 21 and the second side portion 22 are arranged opposite to each other at intervals, and one end of the first side portion 21 and one end of the second side portion 22 are connected in a U-shape through the middle portion 23. When the first side portion 21 is inserted between the third side portion 11 and the fourth side portion 12 of the frame, the fourth side portion 12 is also inserted between the first side portion 21 and the second side portion 22, so that the second side portion 22 of the adapter 2 is opposite to the fourth side portion 12 of the frame, and the second side portion 22 is located on the side of the fourth side portion 12 facing the outside of the outer shell body 1.

[0035] A groove 25 is provided on the second side portion 22 to install a slidable lock lug 3 on the outside of the frame; in this embodiment, preferably, the end of the second side portion 22 away from the middle portion 23 is bent so that the second side portion 22 forms a U-shaped groove with an opening facing the middle portion 23, and both ends of the U-shaped groove in the length direction are also open; the U-shaped groove is the groove 25 of the sliding connection portion 31 for installing the lock lug 3 mentioned above.

[0036] Furthermore, such as Figure 3 and Figure 5 As shown, the sliding connection part 31 is also U-shaped, and the U-shaped sliding connection part 31 is adapted to the U-shaped groove 25, so that the sliding connection part 31 can be inserted into the groove 25 from one end in the length direction of the groove 25. The sliding connection part 31 and the groove 25 are inserted into each other's U-shaped structure, thereby installing the sliding connection part 31 on the groove 25. The sliding connection part 31 can slide along the length direction of the groove 25, so as to adjust the installation position of the lock lug 3 on the frame. At the same time, it is also convenient to install different numbers of lock lugs 3 on the frame according to actual needs.

[0037] In one embodiment of this application, preferably, as shown below, Figure 4 and Figure 5 As shown, when the second side 22 is bent to form the U-shaped groove 25, the end of the second side 22 away from the middle part 23 is bent toward the side of the first side 21, thereby hiding the formed U-shaped groove 25 inside the adapter 2. When the locking lug 3 is installed on the groove 25, the assembly structure between the two can also be hidden, thereby ensuring the overall aesthetics of the battery casing.

[0038] In one embodiment of this application, preferably, the third side 11 of the frame faces the interior of the outer casing 1, and a notch is provided on the third side 11, through which the first side 21 located in the slot 13 of the frame can be exposed.
