Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and specifically relates to a buffer shell and an electrical device. Background Technology

[0002] A battery is a device that converts chemical energy, light energy, and heat energy into electrical energy. It mainly consists of positive and negative electrodes and an electrolyte, generating current through a chemical reaction. Throughout the battery's entire lifecycle, from production and assembly, warehousing and transportation to end-use, the casing, as the core protective structure, not only needs sufficient mechanical strength to withstand external impacts, compression, and vibration, but also needs to provide stable installation space for key components such as the battery cells and circuits. To reduce the damage to the internal structure of the battery caused by external mechanical forces, the industry commonly adopts a protective solution of attaching cushioning cotton to the inner wall of the casing. Currently, the mainstream cushioning cotton materials are mostly polyurethane foam, EVA (ethylene-vinyl acetate copolymer) foam, or pearl cotton. These materials, with their lightweight, low cost, and excellent elastic recovery properties, can effectively absorb external impact forces, reducing structural damage to the battery under scenarios such as transportation bumps and installation collisions. They can also fill the gap between the casing and the battery components, preventing wear caused by the components shaking within the casing.

[0003] However, as batteries develop towards higher energy density and higher power output, the inherent defects of cushioning cotton have gradually become a key bottleneck restricting battery performance and safety. In terms of cushioning performance, its cushioning effect is positively correlated with its thickness. However, excessively thick cushioning cotton can lead to poor battery heat dissipation, causing battery performance and safety issues. If the cushioning cotton is too thin, its cushioning performance is weak, and its buffering protection effect on the battery during transportation is limited, leading to damage from impacts, compression, or vibrations.

[0004] Therefore, a buffer shell is needed to replace the existing buffer cotton for the battery's cushioning effect. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 As shown, a buffer shell according to the present invention includes a shell 1. Several sets of buffers are fixedly installed on the inner bottom surface of the shell 1. Each set of buffers includes multiple buffers 11 and multiple buffers 12. A support plate 10 is fixedly connected to the top surface of the multiple buffers 11. By setting the multiple buffers 11, the support plate 10 is given a buffering function, thereby buffering the impact damage of vibration on the items placed on the support plate 10 during transportation. The support plate 10 has a through slot 14, and the top surfaces of the multiple buffers 12 penetrate the slot 14 to support the items placed on the support plate 10. The multiple buffers 12 provide a buffering function to the items placed on the support plate 10, further buffering the impact damage to the items placed on the support plate 10 caused by vibration during transportation.

[0023] In some embodiments of this utility model, see, for example, for details. Figure 4 A group consists of several sets of buffers. In a group of buffers, there are five buffers 11 and four buffers 2. The five buffers 11 and the four buffers 2 are arranged side by side on the inner bottom surface of the housing 1, wherein the four buffers 2 are arranged symmetrically in pairs.

[0024] In some embodiments of this utility model, for example, the model number of buffer one 11 and buffer two 12 is SCS45-75.

[0025] In some embodiments of this utility model, a set of symmetrical inner walls on both sides of the housing 1 are respectively provided with sliding grooves 9 (see details). Figure 3 A slider 15 is slidably disposed within the groove 9 (see details). Figure 4 The slider 15 is fixedly connected to the support plate 10; The cooperation between the slide groove 9 and the slider 15 allows the support plate 10 to slide along the slide groove 9, making the sliding motion of the support plate 10 more stable during the buffering process.

[0026] In some embodiments of this utility model, heat dissipation grooves 8 are symmetrically formed on the inner walls of the other set of symmetrical sides of the housing 1 (see details). Figure 3 This facilitates heat dissipation for items placed on the support plate 10.

[0027] In some embodiments of this utility model, the heat dissipation groove 8 is square, which can create a vertical heat dissipation space between the housing 1 and the device body 6, thereby improving the heat dissipation capacity. At the same time, it also helps to conduct and disperse heat more evenly from the center of the heat source, avoiding local overheating.

[0028] In some embodiments of this utility model, the bottom surface of the housing 1 is further provided with a first heat dissipation hole to further facilitate heat dissipation of items placed on the support plate 10.

[0029] In some embodiments of this utility model, a limiting cylinder 13 that runs vertically through the inner bottom surface of the housing 1 is provided. The limiting cylinder 13 corresponds one-to-one with the first heat dissipation hole. The setting of the limiting cylinder 13 can play a waterproof role, preventing water from entering the housing 1 from the first heat dissipation hole at the bottom. The opening of the first heat dissipation hole facilitates the discharge of heat from the bottom surface of the device body 6.

[0030] In some embodiments of this utility model, for example, the inner diameter of the limiting cylinder 13 is the same as the diameter of the first heat dissipation hole.

[0031] In some embodiments of this utility model, the top surface of the limiting cylinder 13 is at a horizontal position lower than the bottom surface of the support plate 10, so as to avoid the limiting cylinder 13 affecting the sliding of the support plate 10.

[0032] In some embodiments of this utility model, the limiting cylinder 13 is located below the slot 14 and is staggered from the arrangement of the second buffer 12, so as to avoid the limiting cylinder 13 affecting the function of the second buffer 12.

[0033] In some embodiments of this utility model, a top cover 2 is installed on the top surface of the housing 1 (see details). Figure 2 The top cover 2, in conjunction with the housing 1, can limit and protect the items placed on the support plate 10.

[0034] In some embodiments of this utility model, the top cover 2 is snapped into the housing 1, and the side of the top cover 2 is fixed to the housing 1 by fastening bolts 5, which facilitates the installation and disassembly of the top cover 2 and the housing 1.

[0035] In some embodiments of this utility model, the support plate 10 is configured to place the device body 6, and the top surface of the device body 6 is provided with a top cover 2, that is, the item placed on the support plate 10 is the device body 6.

[0036] In some embodiments of this utility model, the top surfaces of the plurality of buffers 12 pass through the slot 14 and engage with the bottom end of the device body 6.

[0037] In some embodiments of this utility model, a slot 16 is provided on the bottom surface of the device body 6 (see details). Figure 5 The top of the second buffer 12 engages with the slot 16, facilitating the installation and removal of the second buffer 12 from the device body 6.

[0038] In some embodiments of this utility model, a top pressure plate 7 is provided on the top surface of the device body 6, and the top pressure plate 7 is located between the top cover 2 and the device body 6 (see details). Figure 3 The top pressure plate 7 further provides limiting protection for the device body 6.

[0039] In some embodiments of this utility model, the top pressure plate 7 is attached to the top surface of the equipment body 6, and the top pressure plate 7 is fixed to the housing 1 by fastening bolts 5, which facilitates the assembly and disassembly of the top pressure plate 7.

[0040] In some embodiments of this utility model, there is a gap between the top pressure plate 7 and the inner wall of the top cover 2, which further facilitates the heat dissipation of the device body 6.

[0041] In some embodiments of this utility model, the top pressure plate 7 is configured as a plate with holes, which further facilitates heat dissipation of the device body 6. The holes opened on the top pressure plate 7 not only facilitate the dissipation of heat from the device body 6, but also facilitate the disassembly or removal of the top pressure plate 7, and the adjustment of the position of the top pressure plate 7 during the installation process.

[0042] In some embodiments of this utility model, the top cover 2 is provided with a wire hole 3 (see details). Figure 2 The opening of the wire hole 3 facilitates the passage of wires on the device body 6.

[0043] In some embodiments of this utility model, a second heat dissipation hole 4 is also provided on the top cover 2 to further facilitate the heat dissipation of the device body 6. The opening of the second heat dissipation hole 4 allows the heat inside the housing 1 to be quickly dissipated to the outside of the housing 1, thereby further ensuring the heat dissipation function.

[0044] In some embodiments of this utility model, for example, the device body 6 is a battery body.

[0045] Some embodiments of this utility model also provide an electrical device, including a device body 6 and the aforementioned buffer shell; The housing 1 of the buffer shell surrounds the device body 6.

[0046] This invention provides excellent cushioning during battery transportation, as detailed below: During transportation, the buffer 11 enables the support plate 10 to absorb the impact force generated during movement, providing cushioning for the equipment body 6. At the same time, the cooperation between the slide groove 9 and the slider 15 makes the sliding movement of the support plate 10 more stable. The second buffer 12 directly absorbs the impact force during transportation and provides cushioning to the equipment body 6. Its function works in conjunction with the support plate 10 to support and cushion the equipment body 6, thereby maximizing the cushioning effect of the equipment body 6.

[0047] During use, this utility model exhibits excellent heat dissipation performance, as detailed below: The coordinated arrangement of the slot 14, the heat dissipation groove 8, the first heat dissipation hole, and the second heat dissipation hole 4 forms an efficient heat dissipation channel inside the buffer shell, allowing the heat generated by the device body 6 during use to be quickly dissipated through the heat dissipation channel, thus avoiding excessive temperature affecting use or causing safety accidents.

[0048] Moreover, this utility model also has a waterproof function. Through the cooperation of the first heat dissipation hole and the limiting cylinder 13, the waterproof function can be achieved.
