[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] As shown in the figure, a waterproof injection molded shell structure of lithium battery and capacitor combination type, comprising an inner warehouse waterproof shell 1 and a outer warehouse positioning shell 2 set outside the inner warehouse waterproof shell 1, wherein the inner warehouse waterproof shell 1 and the outer warehouse positioning shell 2 are both ABS material, specifically ABS injection molding, so that both have excellent insulation, chemical resistance and mechanical strength.

[0021] The middle part of the inner warehouse waterproof shell 1 is concave downward to form a first containing warehouse 101, and the lithium battery and capacitor are placed in the first containing warehouse 101. In this example, the first containing warehouse 101 has a plurality of warehouse positions for containing lithium batteries, that is, a plurality of lithium batteries can be installed in the inner warehouse waterproof shell 1, which improves the containing number of batteries. In addition, different numbers of capacitors can also be accommodated according to actual needs.

[0022] The middle part of the outer warehouse positioning shell 2 is concave downward to form a second containing warehouse 201 for containing the inner warehouse waterproof shell 1, and the cross-sectional profile of the first containing warehouse 101 and the second containing warehouse 201 is similar to the irregular shape of the ring, as shown in Figs. 1-3 The first containing warehouse 101 is provided with a warehouse position specially used for containing the battery, which is matched with the shape of the battery, so as to better improve the stability of the battery installation. More specifically, after a specified number of batteries are installed in the first containing warehouse 101, the remaining cavity of the first containing warehouse 101 can be installed with capacitors.

[0023] In this example, the cross-sectional profile of the second containing warehouse 201 is similar to that of the first containing warehouse 101, so as to ensure that the inner warehouse waterproof shell 1 can be stably set in the inner part of the outer warehouse positioning shell 2. Further, the upper surfaces of the inner warehouse waterproof shell 1 and the outer warehouse positioning shell 2 are both provided with a positioning plate 3 extending in the horizontal direction, and the two positioning plates 3 are identical in shape and have positioning holes 301 corresponding in position on the surfaces, which are used to install the inner warehouse waterproof shell 1 and the outer warehouse positioning shell 2 at a specified position, so as to install and fix the entire battery pack.

[0024] When the lithium battery and capacitor are installed in the first containing warehouse 101 of the inner warehouse waterproof shell 1, the remaining first containing warehouse 101 is filled with epoxy resin 4, wherein the epoxy resin 4 is located at the outlet position of the first containing warehouse 101, and the upper surface of the epoxy resin 4 is flush with the surface of the positioning plate 3, which is set to separate the space outside the inner warehouse waterproof shell 1 from the space where the battery and capacitor are located.

[0025] The waterproof injection molding shell structure of the lithium battery combined with the capacitor is used by installing the lithium battery and the capacitor into the first containing bin 101 of the inner bin waterproof shell 1 respectively, the lithium battery is installed in the lithium battery bin of the first containing bin 101, and the capacitor is installed in the remaining space. Then the epoxy resin 4 is filled in the remaining space of the first containing bin 101, so that the lithium battery and the capacitor are completely encapsulated. The epoxy resin 4 is filled to the outlet position of the first containing bin 101, and the upper plane of the epoxy resin 4 is flush with the surface of the positioning plate 3, forming a sealing layer, which isolates the space outside the inner bin waterproof shell 1 from the space where the battery and the capacitor are located, effectively preventing moisture and corrosive substances from entering. The inner bin waterproof shell 1 is sleeved in the second containing bin 201 of the outer bin positioning shell 2, so that the two are aligned through the positioning holes 301 on the positioning plate 3, and the inner bin waterproof shell 1 and the outer bin positioning shell 2 are fixed by penetrating the positioning holes 301 with bolts or other fixing members. Then the inner bin waterproof shell 1 and the outer bin positioning shell 2 can be installed together in a designated area (a battery box of a device or a car, etc.), wherein the outer bin positioning shell 2 is fixed in the designated area. When the battery pack needs to be replaced, the inner bin waterproof shell 1 can be disassembled from the outer bin positioning shell 2 without disassembling the outer bin positioning shell 2, so that the old battery can be disassembled, and then a new battery pack (a new inner bin waterproof shell 1 with a battery and a capacitor) is installed in the outer bin positioning shell 2, so that the maintenance and replacement of the battery are completed, which is more convenient and reduces the maintenance and time cost.

[0026] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application.
