[0032] Embodiment 1
[0033] Reference Figure 1 -Attached Figure 4 , Embodiment 1 of the present invention proposes a battery protection shell, which includes: a protection shell body 1, which has an accommodating space inside, and a positioning structure is arranged in the accommodating space for positioning the battery body 4 in the accommodating space; at least one circle of heat-conductive isolation layer 2 is arranged between the upper wall and the lower wall of the protection shell body 1, and the at least one circle of heat-conductive isolation layer 2 surrounds the outer circumference of the positioning structure in circles, so as to form at least two layers of protection cavity 202 between the battery body 4 and the side wall of the protection shell body 1; a first exhaust port 101 is arranged on the side wall of the protection shell body 1, and a second exhaust port 201 is arranged on the heat-conductive isolation layer 2, and an exhaust channel is formed between the second exhaust port 201 and the first exhaust port 101, and the exhaust channel has a plurality of bending parts at least in a first direction a and a second direction b; wherein the first direction a and the second direction b are perpendicular to each other and are respectively perpendicular to the height direction of the protection shell body 1.
[0034] Specifically, the battery protection shell provided in this embodiment is used to protect the battery body 4. The battery body 4 here can be, but is not limited to, a lithium-ion battery, a sodium-ion battery, or other batteries with safety risks. The battery protection shell containing the battery body 4 can be, but is not limited to, used in electronic equipment, electric bicycles, new energy vehicles, electric tools, etc., which are not specifically limited here. The main structure of the battery protection shell is a protection shell, which can position the battery body 4 in its accommodating space, can position the battery body 4, and set at least one circle of thermally conductive isolation layer 2. At least two layers of protective cavity 202 can be formed on the periphery of the battery body 4, and a first exhaust port 101 and a second exhaust port 201 are respectively set on the side wall of the protective shell body 1 and the thermally conductive isolation layer 2 to form an exhaust channel, and the extension of the exhaust channel has multiple bends at least in the second direction b and the second direction b, which can effectively increase the path of the exhaust channel, so that the battery body 4 is inside the protective shell body 1. When an explosion or combustion occurs in the accommodating space inside the protective shell (hereinafter referred to as combustion and explosion), the generated gas, smoke and internal pressure will be rectified through the exhaust channel and orderly conducted to the outside of the protective shell body 1, and in the process of conduction, the thermal conductive isolation layer 2 and the protective shell body 1 have good heat absorption performance, and by fully extending the path of the exhaust channel, the heat energy generated by the combustion and explosion can be fully absorbed. Therefore, after the combustion and explosion occurs, the flame can be locked inside the protective shell body 1, and only the gas and smoke that have absorbed heat are discharged to the outside, which can reduce the impact of the combustion and explosion on the outside and avoid the occurrence of safety accidents.
[0035] The protective shell body 1 is made of a material with high strength and high temperature resistance, for example, it can be made of metal casting, so that the protective shell body 1 has sufficient impact resistance and heat absorption performance, and can resist the high temperature and impact generated by the explosion of the battery body 4; the cross-section of the internal accommodating space of the protective shell body 1 can be rectangular, that is, the protective shell body 1 is a cubic shell structure, and the volume of the accommodating space inside the protective shell body 1 can be set to be larger than the volume of the battery body 4, so that there is sufficient space inside the protective shell body 1 to accommodate the battery body 4 and conduct smoke; a positioning structure is provided in the accommodating space, and the battery body 4 can be positioned in the accommodating space to ensure that the battery protective shell body 1 accommodating the battery body 4 is applied to the device. The internal battery body 4 can maintain a stable positioning; wherein the positioning structure adopted can be a structure that can independently realize the positioning of the battery body 4 in the first direction a, the second direction b and the height direction of the protective shell body 1, or, the positioning structure adopted can also be a structure that cooperates with the protective shell body 1 to realize the positioning of the battery body 4 in the first direction a, the second direction b and the height direction of the protective shell body 1, for example: the accommodating space can be set to adapt to the height of the battery body 4, that is, the positioning of the battery body 4 in its height direction is realized by the protective shell body 1, and the positioning of the battery body 4 in the first direction a and the second direction b is realized by the positioning structure; the specific positioning method of the battery body 4 by the positioning structure will be described in detail below.
[0036] The heat-conducting isolation layer 2 is made of a material with strong thermal conductivity. It can be made of the same material as the protective shell body 1, and can be cast integrally with the protective shell body 1 so that the heat-conducting isolation layer 2 has sufficient strength and impact resistance; the heat-conducting isolation layer 2 can be set in one circle, or multiple circles. When multiple circles of the heat-conducting isolation layer 2 are set, the multiple circles of the heat-conducting isolation layer 2 can be concentrically arranged and each circle is a closed ring. In this case, the multi-layer protective cavities 202 formed are independent of each other and can only be connected through the second exhaust port 201, or the multiple circles of the heat-conducting isolation layer 2 can be formed into a spiral shape, so that the multi-layer protective cavities 202 formed are connected to each other and can be connected through the second exhaust port 201. Further connected; the heat-conducting isolation layer 2 is arranged between the upper wall and the lower wall of the protective shell body 1, and surrounds the periphery of the positioning structure, so that at least two layers of protective cavities 202 can be formed on the periphery of the battery body 4. The battery body 4 is protected by the formation of the protective cavity 202. When the battery body 4 explodes, on the one hand, the impact can be mitigated layer by layer through the multi-layer protective cavity 202, and the second exhaust port 201 of the heat-conducting isolation layer 2 and the first exhaust port 101 of the protective shell body 1, and the exhaust channel formed by the protective cavity 202 can be used to discharge the gas and smoke generated by the explosion, and the generated heat can be efficiently conducted and adsorbed; wherein, the attached Figure 1The arrows on the middle dotted line indicate the direction of smoke flow and pressure relief in the exhaust duct.
[0037] According to the above, an embodiment of the present invention provides a battery protection shell, wherein the protective shell body 1 can accommodate and reliably position the battery body 4, and by providing at least one circle of heat-conducting isolation layer 2, at least two layers of protective cavity 202 can be formed on the periphery of the battery body 4, and by providing a first exhaust port 101 and a second exhaust port 201 on the side wall of the protective shell body 1 and the heat-conducting isolation layer 2, respectively, to cooperate with the protective cavity 202 to form an exhaust channel, and by providing the exhaust channel with multiple bends to increase the path of the exhaust channel, so that the battery body 4 explodes or burns in the accommodation space inside the protective shell body 1 (hereinafter referred to as During the explosion, the generated gas, smoke and internal pressure will be rectified through the exhaust channel and orderly conducted to the outside of the protective shell body 1, and in the process of conduction, the thermal insulation layer 2 and the protective shell body 1 have good heat absorption performance, and by fully extending the path of the exhaust channel, the heat energy generated by the explosion can be fully absorbed. Therefore, after the explosion occurs, the flame can be locked inside the protective shell body 1, and only the gas and smoke that have absorbed heat are discharged to the outside, which can reduce the impact of the explosion of the battery body 4 on the outside of the protective shell body 1, and avoid posing a serious threat to other components of the equipment, the safety of users and the surrounding environment.

[0039] Specifically, in order to facilitate the installation and disassembly of the protective shell body 1, in the technical solution adopted by the present invention, the protective shell body 1 can be set as a split structure divided into two parts in the height direction, including an upper shell body 11 and a lower shell body 12, and the upper shell body 11 and the lower shell body 12 can be detachably connected. Specifically, a plurality of ear pieces with connecting holes can be respectively provided on the connecting surfaces of the upper shell body 11 and the lower shell body 12, and bolts are passed through the connecting holes of the ear pieces corresponding to the upper shell body 11 and the lower shell body 12, and the connecting nuts are locked, so as to achieve a reliable connection between the upper shell body 11 and the lower shell body 12; the dimensions of the upper shell body 11 and the lower shell body 12 in the height direction of the protective shell body 1 can be equal, that is, the upper shell body 11 and the lower shell body 12 can or may not be equal, for example: the lower shell body 12 can be the main structure of the protective shell body 1, and the upper shell body 11 serves as a cover structure; two positioning structures can be provided, which are respectively provided at the height of the upper shell body 11 and the lower shell body 12. Surfaces opposite to each other in the degree direction, or a positioning structure may also be provided, which is provided on the upper shell body 11 or the lower shell body 12; the heat-conducting isolation layer 2 may extend from the upper wall to the lower wall of the protective shell body 1, and it may be an integral structure, which is provided on the upper shell body 11 or the lower shell body 12, or the heat-conducting isolation layer 2 may also be a split structure, that is, the upper shell body 11 and the lower shell body 12 are respectively provided with a part of the heat-conducting isolation layer 2, and the sizes of the two parts of the heat-conducting isolation layer 2 in the height direction may be equal, or may not be equal. In the case where the heat-conducting isolation layer 2 is provided as a split structure, the second exhaust port 201 may be provided in one part, or the second exhaust port 201 may also be formed by the two parts of the heat-conducting isolation layer 2 being jointly provided. Taking the second exhaust port 201 as a circular hole as an example, the second exhaust port 201 may be composed of a semicircular hole corresponding to the connection between the two parts of the heat-conducting isolation layer 2, which may be specifically set according to the position of the second exhaust port 201 in the height direction.
[0040] For further information, see Attachment Figure 1 and attached Figure 2 In a specific implementation, at least one first exhaust port 101 may be provided on the two opposite side walls of the protective shell body 1 in the first direction a. In this case, in order to extend the extension path of the exhaust channel, there are multiple ways to arrange the second exhaust port 201. Two arrangement schemes are described below by way of example:
[0041] When a circle of heat-conducting isolation layer 2 is provided, as shown in the attached Figure 1 and attached Figure 2 As shown, the second exhaust port 201 may be disposed on two side walls of the heat-conducting isolation layer 2 opposite to each other in the second direction b, and each side wall may be provided with a plurality of second exhaust ports 201, and the plurality of second exhaust ports 201 may be distributed at equal intervals along the first direction a;

[0044] Therefore, when the heat-conducting insulation layer 2, i.e., the second exhaust port 201, is provided, the positions of the two circles of heat-conducting insulation layers 2 located on both sides of each layer of the protective cavity 202, or the exhaust ports on the heat-conducting insulation layer 2 and the protective shell body can be fully staggered, so that the smoke can fully flow a certain distance in each layer of the protective cavity 202, so as to achieve full contact with the heat-conducting insulation layer 2 and the protective shell body 1, and enhance the absorption effect of the heat-conducting insulation layer 2 and the protective shell body on the heat energy of the smoke;
[0045] Among them, the first exhaust port 101 and the second exhaust port 201 can be located at different heights, that is, they are staggered in the height direction, or they can also be located at the same height, that is, they are correspondingly arranged in the height direction; when multiple circles of thermally conductive isolation layer 2 are set, the second exhaust ports 201 of adjacent circles of thermally conductive isolation layer 2 can be located at different heights, or they can also be located at the same height, which is not specifically limited here; in the height direction, the first exhaust port 101 and the second exhaust port 201 set in the protective shell body 1 and the thermally conductive isolation layer 2 are not limited to one row, and can be set according to actual needs.
[0046] In addition, a fairing can be provided on the outside of the protective shell body 1 corresponding to each first exhaust port 101. The fairing can be used to rectify and optimize the smoke discharged from the protective shell body 1, and can guide the smoke to flow more smoothly through the first exhaust port 101, thereby reducing smoke turbulence and vortex phenomena, thereby reducing exhaust resistance.

The ceramic material has high temperature resistance and can remain stable when the temperature of the protective shell body 1 is high. It also has heat insulation properties and can avoid the impact of the high temperature of the protective shell body 1 on other parts of the device. In addition, a ceramic structure can be set at a position on the protective shell body 1 that is easy to contact with adjacent parts in the device for isolation.
[0051] For further information, see Attachment Figure 2 In a specific implementation, a ceramic plug socket 5 is provided on the protective shell body 1 for connecting the plug of the battery body 4.
