DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] The embodiment of the present invention discloses a new energy battery pack housing with impact resistance, such as Figure 1-11 As shown, it comprises: a main shell 1 with an internal cavity, the main shell 1 is a square structure with one end open and the other end closed, a plurality of mounting columns 11 distributed in a matrix are arranged in the main shell 1, and a compression spring 2 is placed in each mounting column 11; A protection plate 3 and a partition frame 4 are placed in the main shell 1. The protection plate 3 abuts against the compression spring 2 and the partition frame 4 respectively. The partition frame 4 is used to separate and install the cells in the shell of the new energy battery pack. At least one first buffer component 5 is installed between the main shell 1 and the partition frame 4. Each first buffer component 5 is located in the length direction of the main shell 1. A detachably connected top cover 6 is mounted on the main shell 1, and the top cover 6 is used to close the opening of the main shell 1. In this embodiment, the main shell 1 and the top cover 6 are both made of PVC plastic material, and the protection plate 3 is made of polycarbonate material, so that the protection plate 3 has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame retardancy, and anti-aging, and can protect the battery cells in the shell of the new energy battery pack.

[0024] It should be noted that the battery cells in the shell of the new energy battery pack are separated and installed by the partition frame 4, the protection plate 3 provides impact protection for the battery cells, the compression spring 2 and the first buffer assembly 5 both play a buffering role to buffer the external impact force, which can enhance the impact resistance of the shell of the new energy battery pack and avoid fire caused by external collision of the new energy battery.

[0025] It should also be noted that, due to the provision of the protection plate 3 and the gap between the inner bottom wall of the main shell 1 and the protection plate 3, the battery cells in the new energy battery pack shell can be effectively prevented from being damaged by collision with external hard objects. The protection plate 3 is provided with a through hole 31; the provision of the through hole 31 facilitates maintenance personnel to remove the protection plate 3 from the main shell 1.

[0026] In an optional embodiment, a plurality of partition chambers 43 for accommodating battery cells are provided in the partition frame 4, and steps 44 for supporting the battery cells are provided in the partition chambers 43; by providing the steps 44, the distance between the outer bottom wall of the main shell 1 and the battery cells is increased, thereby reducing the risk of the battery cells in the new energy battery pack shell being punctured by external hard objects, thereby improving the impact resistance of the new energy battery pack shell.

[0027] like Figure 8 and Fig.11As shown, the partition frame 4 is provided with a liquid storage cavity for storing coolant, a first sealing film 45 for closing the opening of the liquid storage cavity is provided on the side wall of the partition frame 4, and a puncture column 18 corresponding to the first sealing film 45 is provided on the inner side wall of the main shell 1. In the specific implementation process, the puncture column 18 and the main shell 1 are an integrally formed structure, and the first sealing film 45 is adhered to the side wall of the partition frame 4.

[0028] It should be noted that the coolant has a cooling effect and can cool the shell of the new energy battery pack; when the outer wall of the main shell 1 is subjected to a strong collision, the buffering effect of the first buffer assembly 5 is difficult to take effect, so that the puncture column 18 pierces the first sealing membrane 45, and the coolant in the liquid storage cavity flows out, thereby cooling the shell of the new energy battery pack and preventing fire; flame retardants can also be added to the coolant to further enhance the impact resistance of the shell of the new energy battery pack.

[0029] like Fig.11 As shown, a liquid injection hole 46 communicating with the liquid storage chamber is provided at the top of the partition frame 4, and a second sealing film 47 is provided at the liquid injection hole. In this embodiment, since the liquid injection hole 46 is provided at the top of the partition frame 4, the coolant can be injected after the partition frame 4 is installed in the main shell 1, and the second sealing film 47 is pasted to seal it.

[0030] like Figure 7 As shown, the first buffer assembly 5 and the partition frame 4 are installed using the following method: Obtain a first buffer component 5 in a compressed state, and bundle the first buffer component 5 in the compressed state with a cable tie; wherein the number of the cable ties may be two or more, and the cable ties are widely available and low in cost, and are used separately; The partition frame 4 pre-installed with the first sealing film 45 is placed in the main shell 1, and the partition frame 4 is installed at a preset position using an external spacer block; wherein the width of the spacer block is not limited, and the first buffer component 5 can be placed at different compression levels to achieve adjustable buffering; The first buffer component 5 is placed between the partition frame 4 and the main shell 1. After the cable tie is cut, the first buffer component 5 rebounds and expands outward. The first buffer component 5 abuts against the main shell 1 and the partition frame 4 respectively, so that the first buffer component 5 is installed in the preset position; Coolant is injected into the injection hole 46. When a preset amount of coolant is stored in the liquid storage cavity, the second sealing film 47 is installed at the injection hole 46. It should be noted that by positioning and installing the first buffer assembly 5 and the partition frame 4 before injecting the coolant, the partition frame 4 can be easily installed; if the coolant is injected into the liquid storage cavity first, the partition frame 4 is heavy and inconvenient to install; and after the first sealing film 45 and the second sealing film 47 are punctured, the coolant is likely to flow out in advance, resulting in a waste of resources.

[0031] like Figure 2, Figure 3 , Figure 7 and Fig. 9 As shown, the first buffer assembly 5 includes a first connecting plate 51, a first buffer spring 52 and a first mounting plate 53 connected in sequence, a first fireproof plate 54 is mounted on the first connecting plate 51, and a first buffer pad 55 is mounted on the first mounting plate 53. It should be noted that the number of first buffer assemblies 5 can be one, two, or more; multiple first buffer assemblies 5 can be symmetrically distributed at opposite ends of the partition frame 4; the number of first buffer springs 52 located between the first connecting plate 51 and the first mounting plate 53 is not limited, and the number of first buffer springs 52 in this embodiment is set to three. Through the buffering effect of the first buffer spring 52, the influence of external impact force on the battery cells in the shell of the new energy battery pack can be weakened, thereby improving the impact resistance of the shell of the new energy battery pack.

[0032] In this embodiment, the first fireproof board 54 is made of fireproof material, and the first fireproof board 54 can be a metal board or a non-metal board; illustratively, the first fireproof board 54 is a steel board, or the first fireproof board 54 is a cement board, or the first fireproof board 54 is a mineral wool board, etc. The first buffer pad 55 is made of silica gel or EVA material.

[0033] It should be noted that by setting the first fireproof plate 54, the fireproof performance of the new energy battery pack shell can be improved; by setting the first buffer pad 55, the buffering capacity of the first buffer assembly 5 can be further improved, reducing the impact of external forces on the new energy battery pack shell, and improving its impact resistance.

[0034] In this embodiment, the first connecting plate 51 and the first mounting plate 53 may be made of metal material, one end of the first buffer spring 52 is welded and fixed to the first connecting plate 51 , and the other end of the first buffer spring 52 is welded and fixed to the first mounting plate 53 .

It should be noted that by preparing the first buffer components 5 in a compressed state, it is convenient to quickly install multiple first buffer components 5 between the main shell 1 and the partition frame 4, and then cut the cable ties with scissors to make the first buffer components 5 rebound and expand outward, and the first buffer components 5 are respectively abutted against the main shell 1 and the partition frame 4, so that multiple first buffer components 5 can be quickly positioned and installed.

[0036] In an optional embodiment, an integrally formed first connecting column (not shown) is provided on the first connecting plate 51, an integrally formed first mounting column 11 (not shown) is provided on the first mounting plate 53, and the first buffer spring 52 is respectively sleeved with the first connecting column and the first mounting column 11. It should be noted that, through the provision of the first connecting column and the first mounting column 11, the first buffer spring 52 can be sleeved and installed.

[0037] In an optional embodiment, a first positioning groove (not shown) is provided on the first connecting plate 51 and the first mounting plate 53, and the end of the first buffer spring 52 is embedded in the first positioning groove. Through the setting of the first positioning groove, the first buffer spring 52 can be quickly positioned and installed.

[0038] like Figure 7 and Figure 8 As shown, a first connection groove 12 for placing a first connection plate 51 is provided in the main shell 1, and a first installation groove 41 for installing a first installation plate 53 is provided on the partition frame 4.

It should be noted that, through the arrangement of the first buffer assembly 5 and the second buffer assembly 7, the partition frame 4 can be buffered around to buffer the external impact force, and the battery cells in the partition frame 4 can be further protected.

[0040] like Fig. 9As shown, the second buffer assembly 7 includes a second connecting plate 71, a second buffer spring 72 and a second mounting plate 73 connected in sequence. It should be noted that the number of the second buffer assemblies 7 can be one, two, or more; multiple second buffer assemblies 7 can be symmetrically distributed at opposite ends of the partition frame 4; the number of the second buffer springs 72 located between the second connecting plate 71 and the second mounting plate 73 is not limited, and the number of the second buffer springs 72 in this embodiment is set to three. Through the buffering effect of the second buffer spring 72, the influence of the external impact force on the battery cells in the shell of the new energy battery pack can be weakened, thereby improving the impact resistance of the shell of the new energy battery pack.

[0041] In this embodiment, the second connecting plate 71 and the second mounting plate 73 may be made of metal material, one end of the second buffer spring 72 is welded and fixed to the second connecting plate 71 , and the other end of the second buffer spring 72 is welded and fixed to the second mounting plate 73 .

[0042] In the specific implementation process, the second buffer component 7 is prepared by the following method: Obtain a separate second connecting plate 71, a second buffer spring 72 and a second mounting plate 73; One end of the second buffer spring 72 is welded to the second connecting plate 71, and the other end of the second buffer spring 72 is welded to the second mounting plate 73. It should be noted that the components of the second buffer assembly 7 are welded and mounted, the structure after processing is stable, and the processing efficiency of the second buffer assembly 7 is high.

[0043] In the specific implementation process, the second buffer assembly 7 is installed using the following method: Compressing a plurality of second buffer components 7 and bundling them with cable ties; When the first buffer assembly 5 and the partition frame 4 are positioned and installed, and the liquid storage cavity of the partition frame 4 is filled with coolant, the partition frame 4 and the main shell 1 are separated by another spacer block to leave a preset installation spacing; Place several second buffer components 7 between the partition frame 4 and the main shell 1 in sequence, cut the cable ties, and make the second buffer components 7 rebound and expand outwards, and respectively abut against the partition frame 4 and the main shell 1; When several second buffer components 7 are installed, the spacer blocks and the cut cable ties are removed, thereby achieving the positioning and installation of the second buffer components 7 .

[0044] It should be noted that the second buffer assembly 7 is installed using the above method, which reduces the difficulty of installation and can be processed by a single processing personnel, thereby improving the assembly efficiency and further enhancing the impact resistance of the new energy battery pack shell.

[0045] In an optional embodiment, the second connecting plate 71 is provided with an integrally formed second connecting column (not shown), the second mounting plate 73 is provided with an integrally formed second mounting column 11 (not shown), and the second buffer spring 72 is respectively sleeved with the second connecting column and the second mounting column 11.

It should be noted that since the second rib 15 is arranged vertically and crosswise with the first rib 14 to form a grid-like rib structure, the bottom pressure bearing capacity and impact resistance of the main shell 1 can be further improved, thereby enhancing the impact resistance of the new energy battery pack shell.
