[0038] The following combination Figures 1-8 This application will be described in further detail. Example 1

[0039] This application discloses a new energy storage battery housing.

[0040] Reference Figure 1 , Figure 2 A new energy storage battery box includes a shell 1 and a cover 2. The top wall of the shell 1 has an installation port 16 that communicates with the interior of the shell 1. The cover 2 is hinged to the top wall of the shell 1 to open and close the installation port 16 of the shell 1. In this embodiment, the cover 2 is locked by a latch (not shown in the figure) when closed.

[0041] The shell 1 comprises a main body framework 11 and a plurality of composite panels 12 arranged outside the main body framework 11. In this embodiment, the main body framework 11 is formed by a plurality of aluminum alloy strips which are bolted to form a frame-shaped main body framework 11. The composite panels 12 are carbon fiber reinforced epoxy resin panels which can be bolted to the outside of the main body framework 11. In other embodiments, the composite panels 12 can be connected to the main body framework 11 by buckling. The inner surface of each composite panel 12 is provided with a heat insulation layer (not shown in the figure), which can be a ceramic fiber blanket and is attached to the inner surface of the composite panel 12 by adhesion.

[0042] Referring to Figure 2 , Figure 3 For ease of description, the interior space of the shell 1 is defined as a placement space. A partition plate 13 is fixedly installed in the shell 1 to divide the placement space into a placement area 14 and a cooling area 15. The placement area 14 is located at the top of the cooling area 15 for mounting the battery pack 7. An installation opening 16 is connected to the placement area 14. The partition plate 13 is provided with a plurality of first communication grooves 131. The placement area 14 and the cooling area 15 are connected to each other through the plurality of first communication grooves 131. Opposite inner walls of the placement area 14 are fixedly provided with guide rails 4. The opposite guide rails 4 form a placement position 41 for embedding the battery pack 7. In this embodiment, a plurality of guide rails 4 are arranged along the length direction of the shell 1 to form a plurality of placement positions 41.

[0043] The cooling area 15 is provided with a cooling pipe 3 for introducing cooling liquid. The cooling pipe 3 is arranged in a serpentine shape in the cooling area 15. Both ends of the cooling pipe 3 pass through the shell 1 to be connected to external circulating pumps and other equipment. The cooling area 15 is provided with a restraint strip 17 which is located on the side of the cooling pipe 3 away from the partition plate 13. The restraint strip 17 is connected to the partition plate 13 by bolting. The side wall of the restraint strip 17 is provided with a plurality of restraint curved surfaces 171 for abutting against the cooling pipe 3. The cooling pipe 3 is fixed to the plate surface of the partition plate 13 near the cooling area 15 by the restraint strip 17.

[0044] The cooling area 15 is provided with an air sending member for blowing air towards the first communication grooves 131. The air sending member can be a fan (not shown in the figure) or a gas pipe in other embodiments.

[0045] The implementation principle of the embodiment 1 of the application is as follows: the main framework 11 and the composite panel 12 are combined to form the shell 1, so that the shell 1 is lightweight as a whole and has good structural strength; and the cooling liquid is introduced into the accommodation space through the cooling pipe 3 in the working state of the battery pack 7, so that the possibility of damage of the battery pack 7 caused by excessively high temperature in the shell 1 is reduced. Embodiment 2

[0046] The embodiment of the application discloses a new energy storage battery box.

[0047] The new energy storage battery box disclosed by the embodiment of the application is different from the embodiment 1 in that:

[0048] With reference to Figure 4 , Figure 5 In the embodiment, the positioning convex strip 45 is fixedly installed on the side wall of the guide rail 4 close to the battery pack 7, and the positioning sliding groove 71 for embedding the positioning convex strip 45 is formed in the side wall of the battery pack 7 close to the guide rail 4. The clamping strip 5 for clamping the battery pack 7 is installed on both sides of each guide rail 4. The avoiding grooves 42 are formed in the opposite side walls of the guide rail 4, and the two avoiding grooves 42 are correspondingly arranged with the two clamping strips 5. One side of the clamping strip 5 passes through the corresponding avoiding groove 42 and is slidably connected with the side wall of the main framework 11.

[0049] The shell 1 is provided with the driving assembly 6 for driving the two clamping strips 5 to move close to or away from each other. The driving assembly 6 comprises the driving strip 61, the driving column 62 and the driving piece. The driving strip 61 is slidably installed in the shell 1. The connecting rod 46 is fixedly installed on the side wall of the guide rail 4 away from the positioning convex strip 45. One end of the connecting rod 46 away from the guide rail 4 is fixedly connected with the driving strip 61. The guide rail 4 is slidably installed in the shell 1 through the driving strip 61 so as to be able to move close to or away from the accommodation position 41.

[0050] The driving column 62 is fixedly installed in the inner wall of the avoiding groove 42 of the guide rail 4. The side wall of the clamping strip 5 is provided with the guide sliding groove 51 for embedding the driving column 62. The guide sliding groove 51 comprises the straight section 511 and the inclined section 512. The length direction of the straight section 511 is consistent with the sliding direction of the guide rail 4. One end of the inclined section 512 is connected with one end of the straight section 511 close to the accommodation position 41. When the guide rail 4 slides away from the battery pack 7 under the driving of the driving strip 61, the driving column 62 slides from the inclined section 512 to the straight section 511. When the driving column 62 slides to the straight section 511, the clamping strip 5 clamps the battery pack 7. In addition, it should be noted that, in the embodiment, when the driving column 62 moves to the connection position of the straight section 511 and the inclined section 512, the positioning convex strip 45 of the guide rail 4 is separated from the positioning sliding groove 71 of the battery pack 7.

[0051] With reference to Figure 6The driving member is arranged in the shell 1 to drive the driving strip 61 to slide. The driving member is arranged as a driving screw rod 63. The driving screw rod 63 is rotatably arranged in the shell 1. The driving screw rod 63 is threaded through the driving strip 61. One end of the driving screw rod 63 penetrates through the shell 1 and is fixedly connected with a driving head 631. The cross section of the driving head 631 is polygonal to be connected with a wrench or the like tool. In other embodiments, the driving member can also be arranged as an electric push rod to drive the driving strip 61 to slide.

[0052] The implementation principle of the embodiment 2 is that the positioning convex strip 45 of the guide rail 4 provides the guiding and positioning effect for the placement of the battery pack 7 in the placement position 41. After the battery pack 7 is placed in the placement position 41, the driving strip 61 is driven to slide away from the side of the battery pack 7. The driving column 62 pushes the clamping strip 5 under the action of the guide sliding groove 51, so as to force the clamping strip 5 to clamp and fix the battery pack 7. When the battery pack 7 is clamped and fixed, the guide rail 4 is separated from the battery pack 7, so as to reduce the contact area between the guide rail 4 and the side wall of the battery pack 7, and further improve the heat dissipation effect of the battery pack 7.

[0053] In addition, when the driving column 62 moves to the connection position of the straight section 511 and the inclined section 512, the positioning convex strip 45 of the guide rail 4 is separated from the positioning sliding groove 71 of the battery pack 7. That is, during the sliding process of the driving column 62 in the inclined section 512, the positioning convex strip 45 is not separated from the positioning sliding groove 71, so as to reduce the possibility of position deviation of the battery pack 7 during the sliding process of the guide rail 4, and ensure the installation accuracy of the battery pack 7.
