At present, lithium ion batteries are widely used due to their high energy density and long cycle life. As the physical protection structure of the battery pack, in recent years, the industry has improved the performance by improving the material and optimizing the structure to improve the protection effect of the battery pack, but there are still many challenges.

[0003] In the prior art, the main types of battery boxes are metal boxes and composite material boxes. The metal box is usually made of aluminum alloy or stainless steel by welding, which has high strength and high thermal conductivity, but the weight is large and the cost is high. The composite material box usually uses carbon fiber or glass fiber reinforced plastic to achieve lightweight, but the fireproof performance and impact resistance are weak. Therefore, a new energy energy storage battery box is needed to achieve lightweight while maintaining the overall structural strength. SUMMARY

[0006] By adopting the above technical scheme, the main body framework has good structural strength and impact resistance, and the composite panel is arranged on the outer side of the main body framework. The main body framework and the composite panel are combined to form the shell, so that the battery box maintains good structural strength and the whole is lightweight. Under the working state of the battery pack, the cooling pipe is used to pass in the cooling liquid into the mounting space to exchange heat and reduce the possibility of damage to the battery pack caused by high temperature in the shell.

[0016] By adopting the technical scheme, in the process that the clamping strip clamps the battery pack, one end of the limiting arc strip is pushed by the side wall of the battery pack, so that the limiting end of the limiting arc strip rotates out of the groove and abuts against the side wall of the battery pack close to the guide rail, thereby improving the limiting effect on the battery pack.

[0017] Optionally, a partition plate is arranged in the shell, the partition plate divides the accommodation space into an accommodation area and a cooling area, the battery pack is located in the accommodation area, and the cooling pipe is located in the cooling area; a plurality of first communication grooves are formed in a plate surface of the partition plate, and the cooling area is provided with an air supply member that blows air towards the first communication grooves.

DETAILED DESCRIPTION

[0027] The following Figures 1-8 The application is described in further detail below. Embodiment 1

[0028] The embodiment of the application discloses a new energy energy storage battery box.

[0029] With reference to Figure 1 , Figure 2 A new energy energy storage battery box, comprising a shell 1 and a cover body 2, the top wall of the shell 1 is provided with a mounting port 16 communicating with the inside of the shell 1, and the cover body 2 is hinged to the top wall of the shell 1 to open and close the mounting port 16 of the shell 1; in the embodiment, the cover body 2 is locked when closed by a lock catch (not shown in the figure).

[0030] The shell 1 comprises a main skeleton 11 and a plurality of composite panels 12 arranged outside the main skeleton 11, in the embodiment, the main skeleton 11 is formed by a plurality of aluminum alloy strips in the form of bolt connection to form a frame-shaped main skeleton 11. The composite panel 12 is a carbon fiber reinforced epoxy resin plate, which can be mounted outside the main skeleton 11 in the form of bolt connection, and in other embodiments, the composite panel 12 can be connected to the main skeleton 11 in the form of buckle. 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 felt, and the heat insulation layer is mounted on the inner surface of the composite panel 12 by adhesion.

[0031] With reference to Figure 2 , Figure 3For ease of description, the internal space of the housing 1 is defined as the placement space. A partition plate 13 is fixedly installed inside the housing 1, dividing the placement space into a placement area 14 and a cooling area 15. The placement area 14 is located on top of the cooling area 15 for mounting the battery pack 7, and the mounting port 16 connects to the placement area 14. The surface of the partition plate 13 has multiple first connecting slots 131, and the placement area 14 and the cooling area 15 are interconnected through the multiple first connecting slots 131. Guide rails 4 are fixedly installed on both opposite inner walls of the placement area 14, and the opposite guide rails 4 form placement positions 41 for embedding the battery pack 7. In this embodiment, multiple guide rails 4 are arranged along the length of the housing 1 to form multiple placement positions 41.

[0032] Cooling pipes 3 for introducing coolant are arranged in the cooling zone 15. The cooling pipes 3 are arranged in a serpentine pattern within the cooling zone 15, and both ends of the cooling pipes 3 extend out of the housing 1 for connection to external equipment such as circulation pumps. A restraining strip 17 is installed in the cooling zone 15. The restraining strip 17 is located on the side of the cooling pipes 3 away from the partition plate 13. The restraining strip 17 is connected to the partition plate 13 by bolts. The sidewall of the restraining strip 17 has multiple restraining arc surfaces 171 for abutting against the cooling pipes 3. The cooling pipes 3 are fixed to the surface of the partition plate 13 near the cooling zone 15 by the restraining strip 17.

[0033] An air supply component is installed in the cooling zone 15 to blow air towards the first connecting groove 131. The air supply component can be a fan (not shown in the figure), or in other embodiments, it can be an air pipe, etc. With this design, coolant is introduced into the cooling pipe 3 to reduce the temperature in the cooling zone 15, and the cool air in the cooling zone 15 is blown into the placement zone 14 through the air supply component to improve the heat dissipation effect of the battery pack 7 in the placement zone 14.

[0034] The implementation principle of Embodiment 1 of this application is as follows: This embodiment uses the main frame 11 and the composite panel 12 to form the shell 1, so that the shell 1 is lightweight as a whole and maintains good structural strength. When the battery pack 7 is working, coolant is introduced into the placement space through the cooling pipe 3 to reduce the possibility of the battery pack 7 being damaged due to excessive temperature inside the shell 1. Example 2

[0035] This application discloses a new energy storage battery housing.

[0036] The difference between the new energy storage battery box disclosed in this application and Embodiment 1 is that: Reference Figure 4 , Figure 5In this embodiment, a positioning protrusion 45 is fixedly installed on the side wall of the guide rail 4 near the battery pack 7, and a positioning groove 71 is provided on the side wall of the battery pack 7 near the guide rail 4 for the positioning protrusion 45 to be inserted. Clamping bars 5 for clamping the battery pack 7 are installed on both sides of each guide rail 4. A clearance groove 42 is provided on both opposite side walls of the guide rail 4. The two clearance grooves 42 are correspondingly arranged with the two clamping bars 5. One side of the clamping bar 5 passes through the corresponding clearance groove 42 and is slidably connected to the side wall of the main frame 11.

[0037] The housing 1 is provided with a drive assembly 6 for driving the two clamping bars 5 to move closer to or further away from each other. The drive assembly 6 includes a drive bar 61, a drive column 62 and a drive component. The drive bar 61 is slidably installed in the housing 1. A connecting rod 46 is fixedly installed on the side wall of the guide rail 4 away from the positioning protrusion 45. The end of the connecting rod 46 away from the guide rail 4 is fixedly connected to the drive bar 61. The guide rail 4 is slidably installed in the housing 1 through the drive bar 61 so that it can move closer to or further away from the placement position 41.

[0038] The drive column 62 is fixedly installed on the inner wall of the clearance groove 42 of the guide rail 4. The side wall of the clamping bar 5 is provided with a guide groove 51 for the drive column 62 to be inserted. The guide groove 51 includes a straight section 511 and an 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 to the end of the straight section 511 near the placement position 41. When the drive bar 61 drives the guide rail 4 to slide away from the battery pack 7, the drive column 62 slides from the inclined section 512 to the straight section 511. When the drive column 62 slides to the straight section 511, the clamping bar 5 clamps the battery pack 7. It should also be noted that in this embodiment, when the drive column 62 moves to the connection between the straight section 511 and the inclined section 512, the positioning protrusion 45 of the guide rail 4 disengages from the positioning groove 71 of the battery pack 7.

[0039] Reference Figure 6 A driving component is disposed within the housing 1 to drive the drive bar 61 to slide. The driving component is a drive screw 63, which is rotatably mounted within the housing 1. The drive screw 63 is threaded through the drive bar 61, and one end of the drive screw 63 protrudes from the housing 1 and is fixedly connected to a drive head 631. The drive head 631 has a polygonal cross-section for connecting tools such as wrenches. In other embodiments, the driving component can also be an electric actuator, which drives the drive bar 61 to slide.

[0040] The implementation principle of Embodiment 2 of this application is as follows: the positioning protrusion 45 of the guide rail 4 provides a 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, it drives the drive bar 61 to slide away from the battery pack 7. The drive column 62 pushes the clamping bar 5 under the action of the guide groove 51, thereby forcing the clamping bar 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, thereby reducing the contact area between the guide rail 4 and the side wall of the battery pack 7, and thus improving the heat dissipation effect of the battery pack 7.

[0041] In addition, when the drive column 62 moves to the connection between the straight section 511 and the inclined section 512, the positioning protrusion 45 of the guide rail 4 disengages from the positioning groove 71 of the battery pack 7; that is, during the sliding process of the drive column 62 in the inclined section 512, the positioning protrusion 45 does not disengage from the positioning groove 71, thereby reducing the possibility of the battery pack 7 shifting position during the sliding process of the guide rail 4 and ensuring the installation accuracy of the battery pack 7. Example 3

[0042] This application discloses a new energy storage battery housing.

[0043] The difference between the new energy storage battery box disclosed in this application and Embodiment 2 is that: Reference Figure 7 In this embodiment, when the guide rail 4 slides away from the battery pack 7 and the clamping strip 5 clamps the battery pack 7, for ease of description, the space enclosed by the guide rail 4, the battery pack 7, and the two clamping strips 5 is defined as the cooling channel 43. The clamping strip 5 has multiple grooves 52 on its side wall near the battery pack 7, and these grooves 52 are spaced apart along the length of the clamping strip 5 (only one is shown in the figure). The cooling channel 43 connects to the placement area 14 through the grooves 52. The partition plate 13 has a second connecting groove 132 on its surface. One end of the second connecting groove 132 connects to the cooling channel 43, and the other end connects to the cooling area 15. The cooling channel 43 connects to the cooling area 15 through the second connecting groove 132.

[0044] The groove 52 has a guide surface 521. The side wall of the guide rail 4 near the battery pack 7 has an arc surface 44 for guiding airflow toward the side wall of the battery pack 7. There are two arc surfaces 44 on the guide rail 4. The two arc surfaces 44 are corresponding to the two clamping bars 5. Each arc surface 44 is tangent to the guide surface 521 of the groove 52 of the corresponding clamping bar 5. The positioning protrusion 45 is located between the two arc surfaces 44. The positioning protrusion 45 has a chamfered surface 451. The airflow guided by the two arc surfaces 44 collides in the positioning groove 71.

[0045] The implementation principle of Embodiment 3 of this application is as follows: After the guide rail 4 disengages from the side wall of the battery pack 7 and the clamping strips 5 clamp and fix the battery pack 7, the guide rail 4, the battery pack 7, and the two clamping strips 5 together form a cooling channel 43. Cold air from the cooling zone 15 is blown into the placement zone 14, and the airflow in the placement zone 14 can enter the cooling channel 43 through the groove 52. This allows for heat exchange on the side wall of the battery pack 7 near the guide rail 4, and then the airflow returns to the cooling zone 15 through the second connecting groove 132, forming an airflow circulation loop and improving the cooling effect on the battery pack 7.

[0046] With the arc surface 44 and the guide surface 521 set to be tangent, the airflow enters the cooling channel 43 through the groove 52 and is then blown towards the side wall of the battery pack 7 near the guide rail 4 under the guidance of the arc surface 44, thereby improving the heat dissipation effect on the battery pack 7. Example 4

[0047] This application discloses a new energy storage battery housing.

[0048] The difference between the new energy storage battery box disclosed in this application and embodiment 3 is that: Reference Figure 8 In this embodiment, a rotating arc groove 522 is formed on the inner wall of the groove 52 of the clamping bar 5. A limiting arc bar 53 is rotatably installed in the rotating arc groove 522. One end of the limiting arc bar 53 forms a limiting end 531, which is used to abut against the side wall of the battery pack 7 near the guide rail 4. A return spring 54 is provided between the limiting arc bar 53 and the clamping bar 5. One end of the return spring 54 is fixedly connected to the limiting arc bar 53, and the other end is fixedly connected to the inner wall of the rotating arc groove 522. Under normal conditions, the return spring 54 forces the limiting end 531 to move into the groove 52. When the clamping bar 5 clamps the battery pack 7, the limiting end 531 of the limiting arc bar 53 rotates out of the groove 52 and abuts against the side wall of the battery pack 7 near the guide rail 4.

[0049] The implementation principle of Embodiment 4 of this application is as follows: by setting the limiting arc strip 53, during the process of clamping the battery pack 7 by the clamping strip 5, one end of the limiting arc strip 53 is pushed by the side wall of the battery pack 7, so that the limiting end 531 of the limiting arc strip 53 rotates out of the groove 52 and abuts against the side wall of the battery pack 7 near the guide rail 4, thereby improving the limiting effect on the battery pack 7.

[0050] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
