Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 5, the present embodiment discloses a battery convenient to assemble, which includes a housing 1 and a battery cell assembly 2, where the housing 1 includes an upper casing 11 and a lower casing 12, an opening 123 is disposed at an upper end of the lower casing 12, the opening 123 is communicated with an internal cavity of the lower casing 12, the opening 123 is rectangular, a length of the opening 123 is larger than a size of one side of the battery cell assembly 2, and a width of the opening 123 is equal to a size of the other side of the battery cell assembly 2.

Still include two and step up board 3, electricity core subassembly 2 is followed opening 123 is packed into in the inside cavity of casing 12 down, and opening 123 length direction's both sides form clearance 124, two step up board 3 and insert respectively in the clearance 124 of electricity core subassembly 2 both sides, it locates to go up the side cover from last casing 11 electricity core subassembly 2 upper end, just go up casing 11 with casing 12 is connected down.

The length of the upper end opening 123 of the lower shell 12 is designed to be larger than the size of one side of the electric core assembly 2, the width of the electric core assembly is designed to be equal to the size of the other side of the electric core assembly 2, so that when the electric core assembly 2 is installed in the shell 1, the electric core assembly is easier to align due to the fact that allowance is left in the length direction for convenient adjustment, the time required by alignment operation is shortened, and the assembly efficiency of the battery is improved.

After the battery pack 2 is installed, the gap 124 between the lower shell 12 and the battery pack 2 in the length direction can be filled with the clamping plate 3 through insertion, so that the battery pack cannot move in the cavity inside the lower shell 12, and the purpose of fixing is achieved.

After the battery pack assembly 2 is installed, the upper shell 11 is covered, and the upper shell 11 and the lower shell 12 are connected into a whole, so that the battery pack is completely wrapped in the shell 1 formed by the upper shell 11 and the lower shell 12, and the battery pack is protected.

The lower end of the upper shell 11 is provided with a lower lap joint part 111, the upper end of the lower shell 12 is provided with an upper lap joint part 121, and the upper lap joint part 121 is overlapped with the lower lap joint part 111. Further, the lower overlapping part 111 is inwardly recessed on the upper housing 11, and a lower end of the lower overlapping part 111 abuts against an upper end of the electric core assembly 2. The upper overlapping part 121 is located outside the lower overlapping part 111, and the outside of the upper overlapping part 121 is flush with the outside of the upper case 11.

The sealing performance of the joint between the upper shell 11 and the lower shell 12 is better by the way that the upper lapping part 121 and the lower lapping part 111 are lapped with each other. Meanwhile, the lower overlapping part 111 is inwardly recessed to provide a receiving space for the upper overlapping part 121, so that the outer side of the upper overlapping part 121 can be flush with the outer side of the upper case 11, thereby improving the overall aesthetic property of the battery case 1. The lower end of the lower lap joint part 111 abuts against the upper end of the cell assembly 2 to limit the upper end of the cell assembly, so that the cell assembly is prevented from moving up and down in the shell 1.

The upper lapping part 121 is provided with a first connecting hole 122, the lower lapping part 111 is provided with a second connecting hole 112 corresponding to the first connecting hole 122, the lower lapping part further comprises a connecting bolt (not shown) and a nut 4, the nut 4 is arranged at the second connecting hole 112 at the inner side of the lower lapping part 111, and the connecting bolt penetrates through the first connecting hole 122 and the second connecting hole 112 from the outer side to be connected with the nut 4. Further, a boss portion 41 is provided on a side of the nut 4 facing the lower overlapping portion 111, and the boss portion 41 is fitted in the second coupling hole 112.

It is preferable that the nut 4 is fixedly provided inside the lower overlapping portion 111, for example, by welding, and when the nut 4 is fixedly provided inside the lower overlapping portion 111, the operator rotates the connecting bolt with a screwdriver outside the housing 1 to connect the connecting bolt and the nut 4, thereby preventing the nut 4 from being turned. The fixing effect of the nut 4 can be improved by providing the boss portion 41 on the side of the nut 4 facing the lower overlapping portion 111, for example, the boss portion 41 can be arranged to be in interference fit with the second connecting hole 112, so as to form a tight-fitting friction force of itself, thereby reducing the impact on the welding position of the nut 4 when screwing the connecting bolt. In addition, with the fitting connection between the boss portion 41 and the second connection hole 112, the contact gap is smaller than when the connection bolt directly passes through the second connection hole 112, thereby improving the sealing property of the connection. The nut 4 with the boss portion 41 can extend the thread of the nut 4 to the boss portion 41, so that the length of the thread of the nut 4 is increased, and the connection strength is higher.
