[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Example

[0022] See also Figure 1-3 The utility model provides a technical solution: a lithium-ion battery module housing, comprising an outer shell 1, a slide rail 7 is symmetrically installed on one side of the outer shell 1, and a slide guide groove 2 is symmetrically provided on the other side, and the slide rail 7 is adapted to the slide guide groove 2;

[0023] A stop structure 3 is provided above the outer shell 1 on one side close to the slideway guide groove 2 .

[0024] like Figure 1 and Figure 3 As shown: the anti-retreat structure 3 includes a protrusion 31; the protrusion 31 is installed on the outer shell 1 and is located directly above the slide guide groove 2; through the above arrangement, when the slide rail 7 is inserted into the slide guide groove 2, the protrusion 31 will be squeezed, and when the slide rail 7 is fully inserted into the slide guide groove 2, the protrusion 31 will bounce back again, limiting the position of the slide rail 7 and avoiding falling off.

[0025] like Figure 3 As shown, a through groove 32 is provided on the outer side of the protrusion 31, and the through groove 32 is "U"-shaped; through the above arrangement, the U-shaped through groove 32 can make the protrusion 31 more convenient to be squeezed.

[0026] like Figure 1 and Figure 2 As shown: a plurality of partition plates 4 are evenly installed on the inner side of the outer shell 1, a lithium battery cell placement cavity 6 is provided between the plurality of partition plates 4, an inner plate 8 is installed in the middle of the inner side of the outer shell 1, and a temperature switch placement groove 5 is evenly opened on the inner plate 8; through the above arrangement, the lithium battery cell placement cavity 6 is used to place the battery cell of the lithium-ion battery, and a temperature switch is installed inside the temperature switch placement groove 5.

[0027] like Figure 2 As shown: heating plate placement grooves 9 are provided between the two sides of the outer shell 1 and the partition plate body 4; through the above arrangement, when the internal temperature is abnormal, the core body is heated by the heating plate.

[0028] like Figure 2 As shown: a wire groove 10 is provided between the outer shell 1 and the top of the partition plate 4; through the above arrangement, the wire groove 10 is used to place the wires inside, which facilitates the connection of the wires.

[0029] like Figure 1 As shown: the outer shell 1 is formed by injection molding of PC, PP or ABS.

[0030] Working principle: Place the core of the lithium-ion battery inside the lithium battery core placement cavity 6, install the temperature switch inside the temperature switch placement groove 5, install the heating plate inside the heating plate placement groove 9, and place and connect all the wires through the wire groove 10. When splicing, insert the slide rail 7 into the slide guide groove 2, and squeeze the protrusion 31 through the slide rail 7. When the slide rail 7 is fully inserted into the slide guide groove 2, the protrusion 31 will bounce back to limit the position of the slide rail 7. Through the slide rail 7 and the slide guide groove 2, multi-module combination splicing can be directly realized externally, and a back-stop device is set, which greatly reduces the manufacturing cost, reduces the pressure of combination installation, and improves space utilization and process efficiency.
