[0027] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0028] This specific embodiment relates to a battery case that can save space, such as Figure 2 and Figure 3 As shown, it includes a battery housing 100 for accommodating batteries. In order to facilitate the transportation of batteries, the battery housing 100 is a rectangular parallelepiped, so that the battery housing 100 is easy to stack. This specific embodiment also includes a battery holder 200 for fixing the battery, and the battery holder 200 is distributed in the battery housing 100 at intervals. The number of battery holders 200 is four and fixed in the battery housing 100. Two battery holders 200 form a group, totaling two groups. Each group of battery holders 200 is penetrated with a number of batteries. The battery is placed horizontally in the battery holder 200.

[0029] like Figures 2 to 5 As shown, the open end of the battery housing 100 is provided with an upper cover 300. After the battery is installed in the battery housing 100 and the circuit or other structures are set, the upper cover 300 will be snapped onto the battery housing 100, thereby completing the sealing of the battery housing 100. The upper cover 300 is snapped with a decorative cover 400. The decorative cover 400 is provided with a handle 410 to facilitate people to take it. The decorative cover 400 is used to cover the upper cover 300 and even the structure inside the battery housing 100. The upper cover 300 is provided with a ring groove 320, and the battery housing 100 is provided with a convex ring 110 snapped into the ring groove 320. The upper cover 300 is snapped onto the battery housing 100 through the convex ring 110 and the ring groove 320. In this way, the upper cover 300 and the battery housing 100 do not need to be fixed by bolts. Space for fixing bolts can be reserved in the battery housing 100. In this way, when the battery housing 100 has the same volume, more batteries can be accommodated, so that more electricity can be stored in the battery housing 100; or when the number of batteries is the same, the volume of the battery housing 100 accommodating the batteries is smaller. The upper cover 300 is fixedly connected to the battery holder 200. The upper cover 300 and the battery holder 200 are both provided with connected screw holes 310. The screws are screwed into the screw holes 310, thereby fixing the upper cover 300 to the battery holder 200.

[0030] like Figure 6As shown, the battery holder 200 is provided with several rows of fixing holes 210, and the batteries are inserted into the fixing holes 210. Because the height of the battery holder 200 where each row of fixing holes 210 is located is different, the number of fixing holes 210 in different rows is also different. The number of fixing holes 210 in each row is seven to nine. The fixing holes 210 in two adjacent rows are staggered to maximize the number of batteries. The vertical distance between two adjacent fixing holes 210 is less than the radius of the fixing holes 210, so that the fixing holes can be arranged more closely. The battery holder 200 is provided with a stopper 220 made of a flexible material. The stopper 220 is a triangular prism. Only one of the battery holders 200 in each group of battery holders 200 is provided with a stopper 220. The stopper 220 is against one end of the battery. Several nickel sheets are also attached to the side of the battery holder 200, and the stopper 220 also has the function of positioning the nickel sheet. Six circumferentially distributed stoppers 220 are arranged on each fixing hole 210. In order to save costs, multiple fixing holes 210 can share one block 220. A cable slot 230 is provided on the battery holder 200. The cable slot 230 is provided on the top of the battery holder 200. The wires in the battery housing 100 are arranged in the cable slot 230.

[0031] like Figure 7 As shown, the battery housing 100 is provided with a handle webbing 500, and the handle webbing 500 is wrapped with a plastic part. The plastic part has the function of protecting human hands. One end of the handle webbing 500 is fixed on the battery housing 100 and the other end is fixed on the upper cover 300. The bottom surface of the battery housing 100 is provided with a bottom insert 120, which makes it easier to take and put the battery when charging.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
