[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3 , the utility model provides an embodiment: a battery pack that can be assembled and spliced, including a battery shell 1 and a battery shell 2, the battery shell 1 and the battery shell 2 are fixedly connected to a fixed block 6 on one side of the outer wall, the battery shell 1 and the battery shell 2 are fixedly connected to a fixed block 7 on the other side of the outer wall, a wedge-shaped slider 9 is slidably connected inside the fixed block 6, a push plate 10 is slidably connected to one side of the fixed block 6, a push block 11 is fixedly connected to the bottom of the push plate 10, both sides of the fixed block 6 are fixedly connected to a slide bar 12, the outer wall of the wedge-shaped slider 9 is slidably connected to the outer wall of the slide bar 12, the outer wall of the slide bar 12 is sleeved with a spring 13, the wedge-shaped slider 9 is slidably connected to one side of the inside of the fixed block 27, both sides of the inner wall of the push plate 10 are slidably connected to a card ball 16, one side of the outer wall of the card ball 16 is fixedly connected to a spring 2, one end of the spring 2 15 is fixedly connected to the inside of the push plate 10, a card slot 14 is opened on the inner wall of the fixed block 6, and the card ball 16 is slidably connected to the inside of the card slot 14;

[0025] Specifically, in the horizontal assembly process of the battery housing 1 and the battery housing 2, we adopted an ingenious fixing mechanism. The core of this mechanism lies in the sliding design of the push plate 10 in the fixed block 6. Specifically, when the push plate 10 slides inside the fixed block 6, the push block 11 at the bottom will push the wedge-shaped slider 9 to slide downward. As the wedge-shaped slider 9 slides out from the inside of the fixed block 6, it will be guided to insert into the inside of the fixed block 2 7. This action effectively fixes the battery housing 1 and the battery housing 2 2 together. In order to further strengthen this assembly, we also introduced spring 2 15 and a card ball 16. When the wedge-shaped slider 9 slides into the inside of the fixed block 2 7, the spring 2 15 will generate a force to prompt the card ball 16 to be stuck into the inside of the card slot 14. In this way, the push plate 10 is fixed, thereby further stabilizing the entire mechanism.

[0026] Reference Figure 1 and Figure 4 The outer walls of the battery housing 1 and the battery housing 2 are provided with a connecting component, the connecting component includes an electrode 1 3 and an electrode 2 17, the electrode 1 3 is electrically connected to the electrode 2 17, the electrode 1 3 and the electrode 2 17 are both fixedly connected to the inside of the battery housing 1 and the battery housing 2, a rectangular array slide 5 is provided on the top of the battery housing 1 and the battery housing 2, and a rectangular array slide rail 8 is fixedly connected to the bottom of the battery housing 1 and the battery housing 2, and the slide rail 8 is slidably connected to the inside of the slide 5;

[0027] Specifically, when the batteries are connected, the electrode 1 3 and the electrode 2 17 can be electrically connected, so that the battery housing 1 1 and the battery housing 2 2 can be used normally, and a slide groove 5 and a slide rail 8 are provided between the battery housing 1 and the battery housing 2 2 to facilitate the combination of multiple batteries.

[0028] Reference Figure 4 and Figure 5 A left-right symmetrical card block 4 is fixedly connected to one side of the outer wall of the battery shell 1, and the card block 4 is slidably connected to one side of the inside of the battery shell 2, and a left-right symmetrical driving slider 22 is slidably connected to one side of the inside of the battery shell 2, and a rotating rod 21 is rotatably connected to the outer wall of the driving slider 22, and a spring 3 19 is fixedly connected to the inside of the driving slider 22, and one end of the spring 3 19 is fixedly connected to the inside of the battery shell 2, and a left-right symmetrical wedge-shaped limit block 18 is fixedly connected to one side of the inside of the battery shell 2, and a left-right symmetrical wedge-shaped limit block 20 is fixedly connected to one side of the inside of the battery shell 2, and a left-right symmetrical fixing clamp 23 is rotatably connected to one side of the outer wall of the driving slider 22;

[0029] Specifically, in the longitudinal assembly process of the battery, the combination of the battery housing 1 and the battery housing 2 is a key link. In order to achieve this combination, we need to use some precise mechanical structures. First, the block 4 on the battery housing 1 is inserted into the interior of the battery housing 2. This action will cause the block 4 to push the driving slider 22 to slide inward. The design of the driving slider 22 is very clever. It can drive the rotating rod 21 to slide inward. At this time, the rotating rod 21 starts to move under the restriction of the wedge-shaped limit block 20. The design purpose of this wedge-shaped limit block is to ensure that the rotating rod 21 can accurately move to the predetermined position. Finally, the rotating rod 21 is stuck in the wedge-shaped limit block 22. 0 and is fixed by the force provided by the spring three 19. As the rotating rod 21 is fixed, the fixing clip 23 starts to work. It will clamp inward due to the retraction of the battery housing two 2 and tightly clamp the clamping block 4. The completion of this series of actions ensures the close combination of the battery housing one 1 and the battery housing two 2. When the battery needs to be taken out, the rotating rod 21 can be slid on the wedge-shaped limit block one 18 to release the restriction on the rotating rod 21, making the removal of the battery simple and convenient. The mechanism is respectively arranged on the inner and outer walls of the battery housing. Due to the special design of the battery housing with a groove, it can be used in an environment that does not interfere with the inside of the battery.

[0030] Working principle: When the battery housing 1 and the battery housing 2 are assembled horizontally, the push plate 10 can slide inside the fixed block 16, so that the push block 11 at the bottom of the push plate 10 pushes the wedge-shaped slider 9 to slide downward, so that the wedge-shaped slider 9 slides out of the fixed block 16 and is inserted into the fixed block 27, so that the battery housing 1 and the battery housing 2 are fixed, and then the force of the spring 2 15 makes the card ball 16 snap into the card slot 14, so that the push plate 10 is fixed, and the mechanism is further fixed. When the battery housing 1 and the battery housing 2 are assembled vertically, the card block 4 on the battery housing 1 can be inserted into the battery housing 2 When the battery case 1 is removed, the locking block 4 will push the driving slider 22 to slide inward, thereby causing the driving slider 22 to drive the rotating rod 21 to slide inward. The rotating rod 21 will move under the restriction of the wedge-shaped limit block 20, and finally get stuck in the groove of the wedge-shaped limit block 20. Due to the force of the spring 3 19, the rotating rod 21 is fixed. The fixing clamp 23 will retract into the battery case 2 and clamp the locking block 4 inward, thereby fixing the battery case 1 and the battery case 2. When taking out, the rotating rod 21 can slide on the wedge-shaped limit block 18, thereby releasing the rotating rod 21 from the restriction of the wedge-shaped limit block 20.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
