[0022] 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.
[0023] Please see Figures 1-3 In this embodiment of the utility model, a tooling for assembling lithium batteries includes a splicing component 1 for assembling and fixing multiple batteries 2. The splicing component 1 includes a front cover plate 1a, splicing parts 1b, and a rear cover plate 1c. The front cover plate 1a, multiple splicing parts 1b, and rear cover plate 1c are assembled horizontally in sequence to achieve the installation and positioning of multiple batteries 2.
[0024] The front cover plate 1a is composed of a cover plate 101, a rectangular side 102, an L-shaped docking seat 103, and a 7-shaped locking block 104. The rectangular side 102 is fixed to one end of the cover plate 101, the L-shaped docking seat 103 is fixed at the four corners of one end of the rectangular side 102, and the 7-shaped locking block 104 is fixed to the end of the L-shaped docking seat 103 away from the rectangular side 102.
[0025] The rear cover plate 1c is composed of a cover plate 101, a rectangular side 102, and an L-shaped docking seat 103. The cover plate 101, the rectangular side 102, and the L-shaped docking seat 103 are connected and fixed in sequence, and a 7-shaped slot 105 is formed on the outer side of the L-shaped docking seat 103 on the rear cover plate 1c.
[0026] The splicing component 1b consists of a rectangular docking frame 107, an L-shaped docking seat 103, a 7-shaped locking block 104, and a 7-shaped locking groove 105. The L-shaped docking seats 103 are symmetrically fixed at the four corner positions at both ends of the rectangular docking frame 107. The 7-shaped locking blocks 104 are respectively fixed to the end faces of the four L-shaped docking seats 103 at the same end of the rectangular docking frame 107. The 7-shaped locking groove 105 is formed on the outside of the four L-shaped docking seats 103 at the other end of the rectangular docking frame 107.
[0027] The front cover 1a is connected to the splicing piece 1b, the two splicing pieces 1b, and the splicing piece 1b to the rear cover 1c by snapping together the 7-shaped card block 104 and the 7-shaped card slot 105. The rectangular structure formed by the rectangular docking frame 107, the cover 101, and the rectangular side 102 is used to provide positioning and storage for the battery 2.
[0028] A partition 108 is fixed in the middle of the inner side of the rectangular docking frame 107. Four partitions 108 are provided, and the four partitions 108 are respectively fixed at the four corner positions of the inner side of the rectangular docking frame 107.
[0029] The distance from the end face of the cover plate 101 to the end face of the partition plate 108 is matched with the thickness of the battery 2, and the inner wall dimensions of the rectangular side 102, the rectangular docking frame 107, and the inner wall dimensions of the distribution trajectory of the four L-shaped docking seats 103 are matched with the outer wall dimensions of the battery 2.
[0030] In this embodiment, when multiple batteries 2 are assembled using this splicing component 1, the assembly method is as follows:
[0031] First, remove the front cover plate 1a and install a battery 2 inside the rectangular side 102 of the front cover plate 1a. Then, remove a splicing piece 1b and align the 7-shaped slot 105 on the splicing piece 1b with the 7-shaped locking block 104 on the front cover plate 1a. While the splicing piece 1b is connected to the battery 2 through the rectangular mating frame 107, the 7-shaped locking block on the front cover plate 1a engages with the inside of the 7-shaped slot 105 on the splicing piece 1b. (It should be noted that the 7-shaped locking block 104 and the 7-shaped slot 105 are aligned.) When the 05 contacts, it first deforms under force. When the front cover 1a and the L-shaped docking seat 103 on the splice 1b are attached, the protrusion of the 7-shaped card block 104 is aligned with the groove of the 7-shaped card slot 105. The 7-shaped card block 104 resets under its own elastic force, so that the protrusion of the 7-shaped card block 104 is inserted into the groove of the 7-shaped card slot 105. At this time, the partition 108 is attached to the end face of the battery 2. In this way, not only is the assembly of the splice 1b and the front cover 1a realized, but also the limiting and fixing of the battery 2 is realized.
[0032] Next, install the second battery 2 onto the inner side of the other end of the assembled rectangular docking frame 107, and then assemble it with the first splicing piece 1b through the second splicing piece 1b. Then, operate in sequence. The number of splicing pieces 1b used depends on how many batteries 2 need to be assembled. The last battery 2 is fixed by assembling it with the last splicing piece 1b through the rear cover plate 1c.
[0033] By combining the above components, different numbers of batteries can be easily assembled. The operation is simple and the assembly is highly flexible.
[0034] It should also be noted that: two vertically distributed 7-shaped locking blocks 104 or two vertically distributed 7-shaped locking slots 105 are fixed on a single L-shaped docking seat 103, which can provide a stable locking force for the splicing component 1. Furthermore, after all the batteries 2 are assembled, the assembled splicing component 1 can be further reinforced by straps on the outside.
[0035] Please refer to this carefully. Figures 1-3 Ventilation openings 109 are provided on both sides and at the top and bottom of the rectangular docking frame 107, and the ventilation openings 109 are connected to the space between the four partitions 108.
[0036] Both the front cover plate 1a and the rear cover plate 1c have through holes 106 that completely penetrate the cover plate 101 on their end faces.
[0037] In this embodiment: the structure of the vent 109 ensures ventilation space between adjacent batteries 2, and the through hole 106 allows good heat dissipation space on the end faces of the two outermost batteries 2. Thus, the assembled battery pack maintains good heat dissipation. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
