[0006] In a first aspect, this utility model provides a module fixing frame, comprising:

[0007] First fixed end plate;

[0008] A reinforcing member, wherein the reinforcing member is disposed on the first fixed end plate, and the end of the reinforcing member away from the first fixed end plate is provided with an elastic snap-fit ​​portion; and

[0009] The second fixed end plate is spaced apart from the first fixed end plate, and the second fixed end plate has a snap-fit ​​hole that engages with the elastic snap-fit ​​part.

[0010] The elastic snap-fit ​​portion is used to undergo elastic deformation during the process of passing through the snap-fit ​​hole to pass through the snap-fit ​​hole; and is used to return to the initial state after passing through the snap-fit ​​hole and abut against the side of the second fixed end plate away from the first fixed end plate, so that the reinforcing member is connected and fixed to the second fixed end plate.

[0011] In an optional embodiment, the elastic snap-fit ​​portion includes a connecting portion and a fixing portion. The connecting portion is disposed on the end face of the reinforcing member, and the fixing portion is connected to the connecting portion and spaced apart from the end face of the reinforcing member. A groove is formed between the fixing portion, the connecting portion, and the end face of the reinforcing member, and the groove engages with the snap-fit ​​hole.

[0012] When the groove mates with the snap-fit ​​hole, the fixing part abuts against the side of the second fixing end plate away from the first fixing end plate, the connecting part abuts against the side wall of the snap-fit ​​hole, and the end face of the reinforcing member abuts against the side of the second fixing end plate near the first fixing end plate.

[0013] In an optional embodiment, at least a portion of the peripheral surface of the fixing part is tapered.

[0014] In an optional embodiment, a snap-fit ​​groove is provided on the side of the second fixed end plate away from the first fixed end plate. The snap-fit ​​groove communicates with the snap-fit ​​hole, and the size of the snap-fit ​​groove is larger than the size of the snap-fit ​​hole.

[0015] The fixing part abuts against the bottom wall of the snap-fit ​​groove.

[0016] In an optional embodiment, the first fixed end plate is provided with a first mounting hole, and the reinforcing member is provided with a second mounting hole, the second mounting hole communicating with the first mounting hole;

[0017] The module mounting bracket also includes fasteners, which pass through both the first mounting hole and the second mounting hole and abut against the elastic snap-fit ​​part and one side of the first fixed end plate to connect and fix the first fixed end plate, the reinforcing member and the second fixed end plate.

[0018] In an optional embodiment, the number of elastic snap-fit ​​portions is multiple, and the multiple elastic snap-fit ​​portions are spaced apart.

[0019] In an optional embodiment, there are multiple reinforcing members and multiple snap-fit ​​holes, with each reinforcing member corresponding to one of the multiple snap-fit ​​holes.

[0020] Secondly, this utility model provides a battery module, including a battery cell and a module fixing frame as described in any of the foregoing embodiments, wherein the battery cell is disposed between the first fixing end plate and the second fixing end plate.

[0021] Thirdly, this utility model provides a battery pack, including the battery module described in the foregoing embodiments.

[0022] Fourthly, this utility model provides a new energy vehicle, including the battery pack described in the foregoing embodiments.

[0023] The beneficial effects of this utility model embodiment include:

[0024] The module mounting bracket includes a first fixed end plate, a reinforcing member, and a second fixed end plate. The reinforcing member is disposed on the first fixed end plate, and an elastic snap-fit ​​portion is provided at the end of the reinforcing member away from the first fixed end plate. The second fixed end plate is spaced apart from the first fixed end plate, and the second fixed end plate has a snap-fit ​​hole that engages with the elastic snap-fit ​​portion. The elastic snap-fit ​​portion is used to undergo elastic deformation during the insertion of the snap-fit ​​hole to pass through it, and to return to its initial state after passing through the snap-fit ​​hole and abut against the side of the second fixed end plate away from the first fixed end plate, so that the reinforcing member is connected and fixed to the second fixed end plate.

[0025] In other words, by providing an elastic locking part at the end of the reinforcing member, its elastic deformation characteristic allows it to easily pass through the locking hole during insertion. After passing through the locking hole, it returns to its initial state under the action of elastic force, thus abutting against the side of the second fixed end plate, thereby locking and fixing the reinforcing member to the second fixed end plate. This locking method is similar to a mortise and tenon structure, which better forms a more stable frame structure with the first fixed end plate, the reinforcing member, and the second fixed end plate. It reduces the likelihood of relative slippage and wobbling between them, improving the overall structural strength and mechanical vibration resistance of the module. When the battery cell is placed between the first and second fixed end plates, it also ensures stable module operation, thereby reducing the risk of battery pack failure under harsh operating conditions and improving the safety and reliability of the battery pack.

[0026] The battery module includes a module mounting bracket, which has all the beneficial effects of the module mounting bracket.

[0027] The battery pack includes a battery module, which has all the beneficial effects of the battery module.

[0028] New energy vehicles include battery packs, which have all the beneficial effects of those battery packs. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] As described in the background section, the battery pack, as a core component of new energy vehicles, directly impacts the sales and use of these vehicles. However, under harsh operating conditions, the mechanical properties of the battery modules in the battery pack decrease, and their internal structure is prone to slippage and vibration, leading to a reduction in the safety and reliability of the battery pack.

[0045] Based on this, please refer to Figures 1-7 This utility model provides a module mounting bracket 100, a battery module 110, a battery pack 1100, and a new energy vehicle 1000, which can effectively improve the aforementioned technical problems. Specifically, it can reduce slippage and shaking, improve the overall structural strength and stability of the module, and thus enhance the safety and reliability of the battery pack 1100. The module mounting bracket 100, battery module 110, battery pack 1100, and new energy vehicle 1000 will be described in detail below.

[0046] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the new energy vehicle 1000 provided in this embodiment, combined with... Figure 1 The new energy vehicle 1000 includes a battery pack 1100 and a vehicle body 1200. The battery pack 1100 is installed on the vehicle body 1200 to provide electrical energy to the vehicle body 1200 so as to realize the various functions of the vehicle body 1200.

[0047] The battery pack 1100 includes a battery casing and a battery module 110. The battery module 110 is disposed inside the battery casing and serves as the energy source for the battery pack 1100, providing various power sources for the use of the new energy vehicle 1000. For those skilled in the art, the battery pack 1100 may also include other structures such as a battery management system, a liquid cooling system, and an electrical system; however, these will not be elaborated upon in this embodiment.

[0048] For details, please refer to Figure 2 , Figure 2 This is a structural schematic diagram of the battery module 110 provided in this embodiment, combined with... Figure 2 The battery module 110 includes a module mounting bracket 100 and battery cells 200, with the battery cells 200 disposed on the module mounting bracket 100. It should be noted that there can be multiple battery cells 200. For example, in this embodiment, the number of battery cells 200 is specifically four. The battery cells 200 are fixed by the module mounting bracket 100 to ensure their stability during normal operation.

[0049] Further, please refer to Figure 3 and Figure 4 , Figure 3 This is a structural schematic diagram of the module fixing bracket 100 provided in this embodiment. Figure 4 This is an exploded view of the module mounting bracket 100 provided in this embodiment. (In conjunction with...) Figure 3 and Figure 4 The module fixing frame 100 includes a first fixing end plate 10, a reinforcing member 20, and a second fixing end plate 30. The reinforcing member 20 is disposed on the first fixing end plate 10, and an elastic snap-fit ​​portion 21 is provided at the end of the reinforcing member 20 away from the first fixing end plate 10. The second fixing end plate 30 is spaced apart from the first fixing end plate 10, and the second fixing end plate 30 has a snap-fit ​​hole 31, which cooperates with the elastic snap-fit ​​portion 21. The elastic snap-fit ​​portion 21 is used to undergo elastic deformation during the process of passing through the snap-fit ​​hole 31 to pass through the snap-fit ​​hole 31; and is used to return to the initial state after passing through the snap-fit ​​hole 31 and abut against the side of the second fixing end plate 30 away from the first fixing end plate 10, so that the reinforcing member 20 is connected and fixed to the second fixing end plate 30.

[0050] In other words, by providing an elastic locking part 21 at the end of the reinforcing member 20, its elastic deformation characteristic allows it to undergo elastic deformation during insertion into the locking hole 31, facilitating its passage. After passing through the locking hole 31, it returns to its initial state under the action of elastic force, thus abutting against the side of the second fixed end plate 30, thereby locking and fixing the reinforcing member 20 to the second fixed end plate 30. This locking method is similar to a mortise and tenon structure, which better forms a more stable frame structure with the first fixed end plate 10, the reinforcing member 20, and the second fixed end plate 30. This prevents relative slippage and wobbling between them, improving the overall structural strength and mechanical vibration resistance of the module. When the battery cell 200 is placed between the first fixed end plate 10 and the second fixed end plate 30, it also ensures stable module operation, thereby reducing the risk of battery pack 1100 failure under harsh operating conditions and improving the safety and reliability of the battery pack 1100.

[0051] It should be noted that, in order to improve the energy density of the battery pack 1100, the battery pack 1100 may include multiple battery modules 110, which are arranged side by side and connected and fixed by structural components. For example, in this embodiment, multiple first fixed end plates 10 and multiple second fixed end plates 30 can be connected together simultaneously by long screws. In this way, coupled with the snap-fit ​​engagement between the elastic snap-fit ​​part 21 and the snap-fit ​​hole 31 provided in the module fixing frame 100, the structural stability of the assembled module is improved.

[0052] Please refer to Figure 5 , Figure 5 This is a structural schematic diagram of the reinforcing member 20 provided in this embodiment, combined with... Figure 5 In order to further improve the stability of the snap-fit ​​and enhance the overall strength and seismic performance of the module structure, the number of elastic snap-fit ​​parts 21 can be set to multiple, and the multiple elastic snap-fit ​​parts 21 are spaced apart.

[0053] It should be noted that in this embodiment, the number of elastic latching portions 21 is specifically four. Of course, in other embodiments, the number of elastic latching portions 21 may also be two, three, or five, etc.

[0054] Furthermore, it should be noted that, in order to further reduce slippage and shaking within the module and improve the overall stability of the module structure, the number of reinforcing members 20 and snap-fit ​​holes 31 can both be set to multiple, with multiple reinforcing members 20 corresponding one-to-one with multiple snap-fit ​​holes 31. That is to say, each end of the reinforcing member 20 can be provided with one or more elastic snap-fit ​​parts 21, so as to snap and fix it to the second fixed end plate 30 at different locations, ensuring the safety and reliability of the battery pack 1100 during operation.

[0055] Combination Figure 3 and Figure 4 In this embodiment, in order to further improve the connection stability and enhance the overall structural strength and vibration resistance of the module fixing frame 100, the module fixing frame 100 also includes fasteners 40.

[0056] Specifically, please combine them together Figures 3-5 The first fixed end plate 10 has a first mounting hole 11, and the reinforcing member 20 has a second mounting hole 23, which communicates with the first mounting hole 11. The fastener 40 passes through both the first mounting hole 11 and the second mounting hole 23 and abuts against the elastic snap-fit ​​part 21 and one side of the first fixed end plate 10 to connect and fix the first fixed end plate 10, the reinforcing member 20 and the second fixed end plate 30.

[0057] It is easy to understand that after the elastic snap-fit ​​part 21 snaps into the snap-fit ​​hole 31, the first fixed end plate 10, the reinforcing member 20 and the second fixed end plate 30 are connected and fixed by the fastening action of the fastener 40, thereby making the overall structure of the module fixing frame 100 more stable and reducing the risk of failure of the battery pack 1100 under harsh working conditions.

[0058] It should be noted that in this embodiment, the first fixed end plate 10, the reinforcing member 20, and the second fixed end plate 30 can be connected and fixed by bolts 41. Combined with... Figure 4 The fastener 40 includes a bolt 41 and a nut 42. The bolt 41 passes through both the first mounting hole 11 and the second mounting hole 23 and is threadedly connected to the nut 42, thereby achieving a fastening effect. Of course, in other embodiments, the connection and fixation can be achieved by means of pin connection, riveting, or bonding.

[0059] Combination Figure 5 It should also be noted that in this embodiment, the reinforcing member 20 is cylindrical in shape, and four elastic snap-fit ​​parts 21 are spaced apart around the axis of the cylindrical reinforcing member 20. The four elastic snap-fit ​​parts 21 together form a deformation space, which is connected to the second mounting hole 23. That is, the fastener 40 passes through the deformation space, the second mounting hole 23 and the first mounting hole 11 at the same time.

[0060] Please refer to Figure 6 , Figure 6 This is a partial structural schematic diagram of the reinforcing member 20 provided in this embodiment, combined with... Figure 4 and Figure 6Specifically, the elastic snap-fit ​​part 21 includes a connecting part 211 and a fixing part 212. The connecting part 211 is disposed on the end face 22 of the reinforcing member 20, and the fixing part 212 is connected to the connecting part 211 and spaced apart from the end face 22 of the reinforcing member 20. A groove 213 is formed between the fixing part 212, the connecting part 211, and the end face 22 of the reinforcing member 20, and the groove 213 mates with the snap-fit ​​hole 31. When the groove 213 mates with the snap-fit ​​hole 31, the fixing part 212 abuts against the side of the second fixing end plate 30 away from the first fixing end plate 10, the connecting part 211 abuts against the side wall of the snap-fit ​​hole 31, and the end face 22 of the reinforcing member 20 abuts against the side of the second fixing end plate 30 close to the first fixing end plate 10. Thus, the reinforcing member 20 is snap-fitted and fixed on the opposite two sides of the second fixing end plate 30, ensuring the stability of the connection.

[0061] It should be noted that, in this embodiment, at least a portion of the peripheral surface of the fixing part 212 is tapered. By providing such a tapered peripheral surface, when the fixing part 212 extends into the snap-fit ​​hole 31, the tapered peripheral surface can provide a guiding effect, allowing it to abut against the inner wall of the snap-fit ​​hole 31 and undergo elastic deformation, thereby making it easier for the fixing part 212 to extend out of the snap-fit ​​hole 31 and improving installation efficiency.

[0062] Further, please refer to Figure 7 , Figure 7 This is a structural schematic diagram of the second fixed end plate 30 provided in this embodiment, combined with... Figure 4 , Figure 6 and Figure 7 The second fixed end plate 30 has a snap-fit ​​groove 32 on the side away from the first fixed end plate 10. The snap-fit ​​groove 32 is connected to the snap-fit ​​hole 31, and the size of the snap-fit ​​groove 32 is larger than the size of the snap-fit ​​hole 31. The fixing part 212 abuts against the bottom wall of the snap-fit ​​groove 32.

[0063] By setting the snap-fit ​​groove 32, the fixing part 212 can easily extend out of the snap-fit ​​hole 31 and abut against the side of the second fixing end plate 30 away from the first fixing end plate 10. After the fixing part 212 abuts against the snap-fit ​​groove 32, it is not easy to shake or slip, thereby further improving the overall structural strength and stability of the module.

[0064] In summary, the embodiments of this utility model provide a module fixing frame 100, a battery module 110, a battery pack 1100, and a new energy vehicle 1000. The module fixing frame 100 includes a first fixing end plate 10, a reinforcing member 20, and a second fixing end plate 30. The reinforcing member 20 is disposed on the first fixing end plate 10, and an elastic snap-fit ​​portion 21 is provided at the end of the reinforcing member 20 away from the first fixing end plate 10. The second fixing end plate 30 is spaced apart from the first fixing end plate 10, and the second fixing end plate 30 has a snap-fit ​​hole 31, which cooperates with the elastic snap-fit ​​portion 21. The elastic snap-fit ​​portion 21 is used to undergo elastic deformation during the process of passing through the snap-fit ​​hole 31 to pass through the snap-fit ​​hole 31; and is used to return to its initial state after passing through the snap-fit ​​hole 31 and abut against the side of the second fixing end plate 30 away from the first fixing end plate 10, so that the reinforcing member 20 is connected and fixed to the second fixing end plate 30. By providing an elastic snap-fit ​​part 21 at the end of the reinforcing member 20, and taking advantage of its elastic deformation characteristics, it can undergo elastic deformation during the insertion into the snap-fit ​​hole 31 to facilitate insertion. After passing through the snap-fit ​​hole 31, it returns to its initial state under the action of elastic force, thereby abutting against the side of the second fixed end plate 30, and can snap-fit ​​and fix the reinforcing member 20 to the second fixed end plate 30.

[0065] As is easily understood, this snap-fit ​​method is similar to a mortise and tenon structure, which can better form a more stable frame structure together with the first fixed end plate 10, the reinforcing member 20 and the second fixed end plate 30. It is not easy for them to slip or shake relative to each other, which improves the overall structural strength and mechanical vibration resistance of the module. When the battery cell 200 is placed between the first fixed end plate 10 and the second fixed end plate 30, it can also make the module operate stably, thereby reducing the failure risk of the battery pack 1100 under harsh working conditions, thus improving the safety and reliability of the battery pack 1100.

[0066] The battery module 110 includes a module mounting bracket 100, which has all the functions and benefits of the module mounting bracket 100.

[0067] The battery pack 1100 includes a battery module 110, which has all the functions and benefits of the battery module 110.

[0068] The new energy vehicle 1000 includes a battery pack 1100, which has all the functions and benefits of the battery pack 1100.

[0069] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
