Detailed implementation manners

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

[0040] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" 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 directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two components. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0041] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] An embodiment of the present invention discloses a new energy battery pack housing with impact resistance, as Figure 1-11 shown, including: a main housing 1 with an internal cavity. The main housing 1 is a square structure with one end open and the other end closed. A plurality of mounting posts 11 distributed in a matrix are provided inside the main housing 1, and a compression spring 2 is placed in each mounting post 11;

[0044] A protection plate 3 and a partition frame 4 are placed inside the main housing 1. The protection plate 3 abuts against the compression spring 2 and the partition frame 4 respectively. The partition frame 4 is used for separately installing the battery cells inside the new energy battery pack housing. At least one first buffer assembly 5 is installed between the main housing 1 and the partition frame 4, and each first buffer assembly 5 is located in the length direction of the main housing 1;

[0045] A detachable top cover 6 is installed on the main housing 1, and the top cover 6 is used to close the opening of the main housing 1. In this embodiment, both the main housing 1 and the top cover 6 are 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, anti-aging, etc., and can protect the battery cells inside the new energy battery pack housing.

[0046] It should be noted that the battery cells in the new energy battery pack housing are separated and installed by the partition frame 4, the protection board 3 protects the battery cells from impact, and both the compression spring 2 and the first buffer assembly 5 play a buffering role to buffer the external impact force, which can enhance the impact resistance of the new energy battery pack housing and avoid the occurrence of fire in the new energy battery due to external collision.

[0047] It should also be noted that due to the arrangement of the protection board 3 and the gap between the inner bottom wall of the main housing 1 and the protection board 3, it can effectively prevent the battery cells in the new energy battery pack housing from being damaged by external hard object collision. The protection board 3 is provided with through holes 31; through the arrangement of the through holes 31, it is convenient for maintenance personnel to take out the protection board 3 from the main housing 1.

[0048] In an alternative embodiment, the partition frame 4 is provided with a plurality of partition cavities 43 for accommodating battery cells, and the partition cavities 43 are provided with steps 44 for supporting the battery cells; through the arrangement of the steps 44, the distance between the outer bottom wall of the main housing 1 and the battery cells is increased, reducing the risk of the battery cells in the new energy battery pack housing being penetrated by external hard objects and enhancing the impact resistance of the new energy battery pack housing.

[0049] As Figure 8 and Figure 11 shown, the partition frame 4 is provided with a liquid storage cavity for storing coolant, the side wall of the partition frame 4 is provided with a first sealing film 45 for closing the opening of the liquid storage cavity, and the inner side wall of the main housing 1 is provided with a puncture post 18 corresponding to the first sealing film 45. In the specific implementation process, the puncture post 18 and the main housing 1 are integrally formed, and the first sealing film 45 is adhered to the side wall of the partition frame 4.

[0050] It should be noted that the coolant plays a role in cooling, and the coolant can cool the new energy battery pack housing; when the outer wall of the main housing 1 is strongly collided, the buffering effect of the first buffer assembly 5 is difficult to take effect, causing the puncture post 18 to puncture the first sealing film 45, and the coolant in the liquid storage cavity flows out to cool the new energy battery pack housing and prevent fire; among them, a flame retardant can also be added to the coolant to further enhance the impact resistance of the new energy battery pack housing.

[0051] As Figure 11 shown, the top of the partition frame 4 is provided with a liquid injection hole 46 communicating with the liquid storage cavity, and a second sealing film 47 is provided at the liquid injection hole. In this embodiment, since the liquid injection hole 46 is opened at the top of the partition frame 4, the coolant can be injected after the partition frame 4 is installed in the main housing 1 and is closed by pasting the second sealing film 47.

[0052] As Figure 7 shown, the first buffer assembly 5 and the partition frame 4 are installed by the following method:

[0053] Obtain the first buffer component 5 in a compressed state. The first buffer component 5 in the compressed state is tied with cable ties. Among them, the number of cable ties can be two or more. The cable ties are widely sourced and low in cost and are used separately.

[0054] Place the partition frame 4 pre-installed with the first sealing film 45 into the main housing 1, and install the partition frame 4 at a preset position with an external spacer block. Among them, the width of the spacer block is not limited, and the first buffer component 5 can be in different compression degrees to achieve adjustable buffering.

[0055] Place the first buffer component 5 between the partition frame 4 and the main housing 1. After cutting the cable ties, the first buffer component 5 rebounds and expands outward, and the first buffer component 5 abuts against the main housing 1 and the partition frame 4 respectively, so that the first buffer component 5 is installed at a preset position.

[0056] Inject coolant into the liquid injection hole 46. After a preset amount of coolant is stored in the liquid storage cavity, install the second sealing film 47 at the liquid injection hole 46. It should be noted that by positioning and installing the first buffer component 5 and the partition frame 4 and then injecting coolant, it is convenient to install the partition frame 4. If coolant is first injected into the liquid storage cavity, the partition frame 4 is heavier and not convenient to install. Moreover, after the first sealing film 45 and the second sealing film 47 are punctured, it is easy to cause the coolant to flow out in advance, resulting in waste of resources.

[0057] As Figure 2 、 Figure 3 、 Figure 7 and Figure 9 shown, the first buffer component 5 includes a first connecting plate 51, a first buffer spring 52 and a first mounting plate 53 connected in sequence. A first fireproof board 54 is installed on the first connecting plate 51, and a first buffer pad 55 is installed on the first mounting plate 53. It should be noted that the number of the first buffer components 5 can be one or two, or multiple. Multiple first buffer components 5 can be symmetrically distributed at opposite ends of the partition frame 4. The number of the first buffer springs 52 located between the first connecting plate 51 and the first mounting plate 53 is not limited. In this embodiment, the number of the first buffer springs 52 is set to three. Through the buffering effect of the first buffer spring 52, the impact of external impact on the battery cells in the new energy battery pack housing can be weakened, and the impact resistance of the new energy battery pack housing is improved.

[0058] In this embodiment, the first fireproof board 54 is made of fireproof material. The first fireproof board 54 can be a metal plate or a non-metal plate. Exemplarily, the first fireproof board 54 is a steel plate, 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 silicone or EVA material.

[0059] It should be noted that by providing the first fireproof board 54, the fireproof performance of the new energy battery pack housing can be improved; by providing 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 housing and enhancing its impact resistance.

[0060] In this embodiment, the first connecting plate 51 and the first mounting plate 53 can be made of metal material. One end of the first buffer spring 52 is fixedly welded to the first connecting plate 51, and the other end of the first buffer spring 52 is fixedly welded to the first mounting plate 53.

[0061] As Figure 9 shown, the first buffer assembly 5 is prepared by the following method:

[0062] Weld one end of the first buffer spring 52 in its natural state to the first connecting plate 51, and weld the other end of the first buffer spring 52 to the first mounting plate 53;

[0063] Bond the first fireproof board 54 to the first connecting plate 51, and bond the first buffer pad 55 to the first mounting plate 53;

[0064] At the same time, compress a number of first buffer assemblies 5 and tie them with cable ties so that the first buffer assemblies 5 are in a compressed state. It should be noted that by preparing the first buffer assemblies 5 in a compressed state, it is convenient to quickly install multiple first buffer assemblies 5 between the main housing 1 and the partition frame 4. Then, cut the cable ties with scissors so that the first buffer assemblies 5 rebound and expand outward, and the first buffer assemblies 5 are respectively abutted against the main housing 1 and the partition frame 4, realizing the quick positioning and installation of multiple first buffer assemblies 5.

[0065] In an alternative embodiment, an integrally formed first connecting post (not shown) is provided on the first connecting plate 51, and an integrally formed first mounting post 11 (not shown) is provided on the first mounting plate 53. The first buffer spring 52 is respectively sleeved on the first connecting post and the first mounting post 11. It should be noted that by providing the first connecting post and the first mounting post 11, the first buffer spring 52 can be sleeved and installed.

[0066] In an alternative embodiment, first positioning grooves (not shown) are provided on both the first connecting plate 51 and the first mounting plate 53. The ends of the first buffer spring 52 are embedded in the first positioning grooves. By providing the first positioning grooves, the first buffer spring 52 can be quickly positioned and installed.

[0067] As Figure 7 and Figure 8As shown in the figure, a first connection groove 12 for placing a first connection plate 51 is provided in the main housing 1, and a first installation groove 41 for installing a first installation plate 53 is provided on the partition frame 4. In the specific implementation process, the first connection plate 51 is entirely embedded in the first connection groove 12, and the first installation plate 53 is entirely embedded in the first installation groove 41. The first installation groove 41 can penetrate through one end face of the partition frame 4 in the vertical direction, or can penetrate through two opposite end faces of the partition frame 4 in the vertical direction.

[0068] As Figure 2 , Figure 3 , Figure 7 and Figure 9 shown, at least one second buffer assembly 7 is installed between the main housing 1 and the partition frame 4, and each second buffer assembly 7 is located in the width direction of the main housing 1. It should be noted that through the arrangement of the first buffer assembly 5 and the second buffer assembly 7, the four sides of the partition frame 4 can be buffered, and the external impact force can be buffered, further protecting the battery cells in the partition frame 4.

[0069] As Figure 9 shown, the second buffer assembly 7 includes a second connection plate 71, a second buffer spring 72 and a second installation plate 73 that are connected in sequence. It should be noted that the number of the second buffer assemblies 7 can be one or two, or multiple; 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 connection plate 71 and the second installation 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 new energy battery pack housing can be weakened, and the impact resistance of the new energy battery pack housing is improved.

[0070] In this embodiment, the second connection plate 71 and the second installation plate 73 can be made of a metal material. One end of the second buffer spring 72 is welded and fixed to the second connection plate 71, and the other end of the second buffer spring 72 is welded and fixed to the second installation plate 73.

[0071] In the specific implementation process, the second buffer assembly 7 is prepared by the following method:

[0072] Obtain a separate second connection plate 71, a second buffer spring 72 and a second installation plate 73;

[0073] Weld one end of the second buffer spring 72 to the second connection plate 71, and weld the other end of the second buffer spring 72 to the second installation plate 73. It should be noted that the various components of the second buffer assembly 7 are installed by welding, and the processed structure is stable, and the processing efficiency of the second buffer assembly 7 is relatively high.

[0074] In the specific implementation process, the following method is adopted for installing the second buffer assembly 7:

[0075] Compress several second buffer assemblies 7 and tie them up with cable ties;

[0076] When the first buffer assembly 5 and the partition frame 4 are positioned and installed, after the liquid storage cavity of the partition frame 4 is filled with coolant, the partition frame 4 and the main housing 1 are separated by another spacer block, leaving a preset installation spacing;

[0077] Place several second buffer assemblies 7 between the partition frame 4 and the main housing 1 in sequence, cut the cable ties, so that the second buffer assemblies 7 rebound and expand outwards, and respectively abut against the partition frame 4 and the main housing 1;

[0078] When several second buffer assemblies 7 are installed, take out the spacer block and remove the cut cable ties, realizing the positioning installation of the second buffer assemblies 7.

[0079] It should be noted that the second buffer assembly 7 is installed by the above method, which reduces the installation difficulty, can be processed by a single processing personnel, improves the assembly efficiency, and further enhances the impact resistance of the new energy battery pack housing.

[0080] In an alternative embodiment, an integrally formed second connecting column (not shown) is provided on the second connecting plate 71, and an integrally formed second mounting column 11 (not shown) is provided on the second mounting plate 73. The second buffer spring 72 is respectively sleeved on the second connecting column and the second mounting column 11. It should be noted that through the setting of the second connecting column and the second mounting column 11, the second buffer spring 72 can be sleeved and installed.

[0081] In an alternative embodiment, second positioning grooves (not shown) are respectively formed on the second connecting plate 71 and the second mounting plate 73. The ends of the second buffer spring 72 are embedded in the second positioning grooves. Through the setting of the second positioning grooves, the second buffer spring 72 can be quickly positioned and installed.

[0082] As Figure 7 and Figure 8 shown, a second connecting groove 13 for placing the second connecting plate 71 is formed in the main housing 1, and a second mounting groove 42 for installing the second mounting plate 73 is formed on the partition frame 4. In the specific implementation process, the second connecting plate 71 is completely embedded in the second connecting groove 13, and the second mounting plate 73 is completely embedded in the second mounting groove 42. The second mounting groove 42 can penetrate through one end face of the partition frame 4 in the vertical direction, or can penetrate through the opposite two end faces of the partition frame 4 in the vertical direction.

[0083] As Figure 7 and Figure 8As shown, at least one first rib 14 is provided inside the main housing 1. It should be noted that by providing the first rib 14, the bottom pressure-bearing capacity and impact resistance of the main housing 1 are improved.

[0084] As Figure 8 shown, at least one second rib 15 is provided inside the main housing 1, and the second rib 15 is arranged perpendicular to and intersecting with the first rib 14. It should be noted that since the second rib 15 is arranged perpendicular to and intersecting with the first rib 14 to form a grid-like rib structure, the bottom pressure-bearing capacity and impact resistance of the main housing 1 can be further improved, thereby enhancing the impact resistance of the new energy battery pack housing.

[0085] As Figure 7 and Figure 12 shown, the main housing 1 and the top cover 6 are fixedly connected by screws (not shown). A positioning hole 16 is provided inside the main housing 1, and a positioning post 61 that is inserted and matched with the positioning hole 16 is provided on the top cover 6. It should be noted that since the main housing 1 and the top cover 6 are fixedly connected by screws, it is convenient to quickly disassemble and assemble the top cover 6. A first mounting hole 17 is provided on the main housing 1, and a second mounting hole 62 is provided on the top cover 6. The screw passes through the second mounting hole 62 and is threadedly connected to the first mounting hole 17. The second mounting hole 62 is a counterbore; the number of the positioning hole 16 and the positioning post 61 is both set to two. The positioning hole 16 is a round hole, and the positioning post 61 is a cylinder.

[0086] As Figure 1 shown, a junction box 8 is installed on the top cover 6. It should be noted that by providing the junction box 8, it is convenient for external devices to be electrically connected to the new energy battery pack.

[0087] Working principle: By providing the first rib 14 and the second rib 15, the bottom pressure-bearing capacity and impact resistance of the main housing 1 can be improved; the battery cells inside the new energy battery pack housing are separated and installed by the partition frame 4, and the protection plate 3 plays a protective role. The protection plate 3 protects the battery cells inside the new energy battery pack housing. Through the buffering effects of the compression spring 2, the first buffer assembly 5 and the second buffer assembly 7, the external impact force is buffered, further protecting the battery cells inside the new energy battery pack housing and enhancing the impact resistance of the new energy battery pack housing.

[0088] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
