These drawings and description, however, are not exclusive and are merely illustrative of the present application. The scope of the present application is not limited to the specific embodiments described herein, but is only limited by the claims. DETAILED DESCRIPTION

[0048] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present application. Instead, it is merely intended to provide an example of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0049] As described in the background, the load bearing of the battery pack in the related art is limited, and is prone to deformation problems caused by being stepped on. The inventor has found that the cause of this problem is that the top surface of the battery pack constitutes at least part of the floor of the vehicle, and the top surface of the battery pack has poor load bearing capacity, and is thus prone to deformation caused by being stepped on.

[0050] To solve the above technical problems, the embodiments of the present application provide a battery box, a battery pack and a vehicle. At least one support assembly is arranged on the side of the box cover facing the ground, and the at least one support assembly is arranged on the side of the box cover facing the battery module. The at least one support assembly includes a support plate, a first support protrusion and a second support protrusion. The first support protrusion extends in a first direction and is located between adjacent battery cells arranged in a second direction, and abuts the battery cells. The second support protrusion extends in the second direction and is located between adjacent battery cells arranged in the first direction, and abuts the battery cells. In this way, there are support protrusions in both the first direction and the second direction. When the box cover is stepped on, the support assembly can withstand greater external pressure, avoiding the battery module from being caused by stepping or other external forces, thereby improving the safety and reliability of the battery pack.

[0051] In addition, the gap between adjacent battery cells is also fully utilized to accommodate the first support protrusion and the second support protrusion, so that the first support protrusion and the second support protrusion abut the battery cells. In this way, the structural stability and pressure resistance of the battery pack are improved without increasing the volume of the battery pack.

[0052] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0053] In order to make the above objectives, characteristics and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0054] Please refer to Figures 1 to 5 The embodiments of the present application provide a battery pack 1000. The battery pack 1000 can be applied to an electrical equipment as an energy storage component. For example, the battery pack 1000 can be applied to a vehicle to provide electrical energy for the vehicle to ensure normal operation of the vehicle.

[0055] Please continue to refer to Figures 1 to 3 The battery pack 1000 includes a battery box 100, and the battery box 100 is adapted to accommodate a battery module 200. For example, the battery module 200 is arranged in the battery box 100. The battery module 200 includes a plurality of battery monomers 210. The plurality of battery monomers 210 are arranged in multiple rows and multiple columns. It should be understood that Figure 4 The plurality of battery monomers 210 in the dashed box in the figure constitute a battery module 200.

[0056] The battery box 100 includes a box cover 110. At least part of the box cover 110 constitutes a floor of the vehicle. That is, part of the box cover 110 constitutes the floor of the vehicle, or the entire box cover 110 constitutes the floor of the vehicle. In this way, the structure of the vehicle can be simplified, and the manufacturing cost of the vehicle can be reduced.

[0057] The battery box 100 further includes at least one support assembly 120, and the at least one support assembly 120 is arranged on the side of the box cover 110 facing the battery module 200. It should be understood that the number of support assemblies 120 can be one, two or even more. For example, the number of support assemblies 120 is two, and the two support assemblies 120 can be arranged staggered to support different areas of the box cover 110.

[0058] It should also be understood that the connection between the at least one support assembly 120 and the box cover 110 can be connected by welding or bonding.

[0059] Please refer to Figure 6 and Figure 7At least one support assembly 120 can include a support plate 121, a first support protrusion 122, and a second support protrusion 123. The support plate 121 is fixedly connected to the side of the box cover 110 facing the battery module 200. In this way, the support plate 121 can be a rectangular structure, which increases the contact area of the support plate 121 and the box cover 110, thereby improving the connection strength of the support plate 121 and the box cover 110.

[0060] The first support protrusion 122 and the second support protrusion 123 are arranged on the side of the support plate 121 facing the battery module 200. The first support protrusion 122 extends in a first direction, and the second support protrusion 123 extends in a second direction and is connected to the first support protrusion 122. Alternatively, the first support protrusion 122 and the second support protrusion 123 are perpendicular to each other, so that the first support protrusion 122 and the second support protrusion 123 form a cross structure.

[0061] The first direction can be the column direction of the battery module 200, or the first direction can be the X direction in the battery module 200. Figure 1 The second direction can be the row direction of the battery module 200, or the second direction can be the Y direction in the battery module 200. Figure 1

[0062] The first support protrusion 122 is located between adjacent battery cells 210 arranged in the second direction and abuts the battery cells 210. The second support protrusion 123 is located between adjacent battery cells 210 arranged in the first direction and abuts the battery cells 210. In this way, there are support protrusions in both the first direction and the second direction. When the box cover 110 is stepped on, the support assembly 120 can withstand greater external pressure, avoiding the battery module 200 from being damaged due to stepping or other external forces, thereby improving the safety and reliability of the battery pack 1000.

[0063] In view of the gaps between two battery cells 210 in the first direction and two battery cells 210 in the second direction. The embodiment also makes full use of the gaps between adjacent battery cells 210 to accommodate the first support protrusion 122 and the second support protrusion 123, so that the first support protrusion and the second support protrusion abut the battery cells 210. In this way, without increasing the volume of the battery pack 1000, the structural stability and pressure resistance of the battery pack 1000 are improved.

[0064] ​In some embodiments, the support plate 121, the first support protrusion 122 and the second support protrusion 123 can be a split structure or a whole structure. For example, the support plate 121, the first support protrusion 122 and the second support protrusion 123 are integrally formed. For example, the support plate 121, the first support protrusion 122 and the second support protrusion 123 are formed synchronously by using a stamping process. The integrally formed design makes the support plate 121 and the first support protrusion 122 and the support plate 121 and the second support protrusion 123 free of connection gaps or weak points, and the whole structure is more solid and can better withstand external pressure or impact force, thereby significantly improving the structural strength and stability of the battery pack 1000.

[0065] In addition, since the support plate 121, the first support protrusion 122 and the second support protrusion 123 are a whole structure, the problems of loose connection, falling off or wear of the split structure are avoided, the risk of failure is reduced, and the reliability of the battery pack 1000 is improved.

[0066] In order to further improve the anti-treading deformation ability of the support assembly 120, the number of the second support protrusions 123 can be multiple, and the multiple second support protrusions 123 are arranged in the first direction. The number of the second support protrusions 123 can be determined according to the number of the battery monomers 210 spanned by the support plate 121 in the first direction.

[0067] In one possible implementation, in the thickness direction of the support plate 121, the support plate 121 includes oppositely arranged first and second surfaces. The first surface can be the top surface of the support plate 121, and the second surface can be the bottom surface of the support plate 121.

[0068] At least one of the first and second surfaces is provided with a first buffer layer 124. The first buffer layer 124 can reduce or even absorb the force generated when the box cover 110 is stepped on, which helps to reduce the wear and fatigue of the box cover 110 and its connected components, thereby helping to prolong the service life of the entire battery box 100 and reducing the frequency of maintenance and replacement. In addition, the introduction of the first buffer layer 124 makes the touch feel when stepping on the box cover 110 softer, reducing noise and vibration, which not only improves the overall quality of the product, but also provides users with a more comfortable user experience.

[0069] It should be noted that the second surface can be a flat plane or have other structures. Exemplarily, the second surface of the support plate 121 is further provided with a groove 125 extending along the first direction. In this way, there is a gap between the buffer layer 124 and the second surface of the support plate 121. This gap can provide additional deformation space when an external force acts, so that the buffer layer 124 can more effectively absorb and disperse impact forces, thereby reducing the pressure transmitted to the battery monomer 210 and improving the impact resistance of the battery pack 1000.

[0070] Please continue to refer to Figure 2 and Figure 3 The battery box 100 further comprises a box 130, and the box 130 is provided with at least one first support beam 131 and at least one second support beam 132. The first support beam 131 extends along the first direction and is connected with the inner wall of the box 130. The second support beam 132 extends along the second direction and is connected with the inner wall of the box 130.

[0071] The at least one first support beam 131 and the at least one second support beam 132 divide the inner cavity of the box 130 into a plurality of accommodation chambers. It should be noted that the components accommodated in each accommodation chamber need to be determined according to the structure of the battery box 100.

[0072] Exemplarily, the number of first support beams 131 is one, and the number of second support beams 132 is two. In this way, the inner cavity of the box 130 can be divided into six accommodation chambers. The size of each accommodation chamber and the structure for accommodation can have multiple choices.

[0073] In some embodiments, the plurality of accommodation chambers comprises a first accommodation chamber 133 adapted to accommodate a battery management module 300. The battery management module 300 is used to be electrically connected with the battery module 200 to control the working state of the battery module 200.

[0074] It should be noted that the number of first accommodation chambers 133 can be one or multiple. For example, please refer to Figure 1 and Figure 2 The first accommodation chamber 133 is provided with a partition beam 136 extending along the first direction, and the partition beam 136 divides the first accommodation chamber 133 into two sub-chambers. In this way, each sub-chamber can be provided with one battery management module 300, so that each battery management module 300 can be electrically connected with part of the battery module 200 to realize the partition management of the battery module. If a certain battery management module 300 or part of the battery module 200 fails, it will not affect the normal operation of other subsystems, thereby improving the reliability and fault tolerance of the entire battery pack 1000.

[0075] In the embodiment, a plurality of second boss structures 138 are arranged on the partition beam 136, so that the top surface of the second boss structure 138 is higher than the top surface of the battery module 200. In this way, the second boss structure 138 is connected with the box cover 110 through a second fixing member (not shown in the figure). The second fixing member can be a bolt.

[0076] At the same time, a plurality of first boss structures 137 are arranged on at least one of the first support beam 131 and the second support beam 132; each first boss structure 137 is connected with the box cover 110 through a first fixing member 139. The first fixing member 139 can also be a bolt.

[0077] The embodiment can provide clear installation positioning reference through the arrangement of the first boss structure 137 and the second boss structure 138, so that the alignment of the box cover 110 and the box body 130 is more accurate, the assembly error is reduced, the installation of the fixing member such as the bolt is facilitated, and the production efficiency and consistency are improved. In addition, the arrangement of the first boss structure 137 and the second boss structure 138 can increase the overall strength of the box cover 110 and increase the anti-treading strength at the battery management module 300.

[0078] In order to further describe the arrangement of the battery module 200 in the battery box body 100, the accommodating cavity of the battery box body 100 includes a plurality of third accommodating cavities 135, and one battery module 200 can be arranged in each third accommodating cavity 135. For example, Figure 2 The number of the third accommodating cavities 135 is four, and the volumes of the four third accommodating cavities 135 can be the same or different. For example, the volumes of two third accommodating cavities 135 are greater than the volumes of the other two third accommodating cavities 135.

[0079] In a possible implementation, the plurality of accommodating cavities of the battery box body 100 include a second accommodating cavity 134, and a power distribution box 400 is arranged in the second accommodating cavity 134. The power distribution box 400 is a key electrical component inside the battery pack. The power distribution box 400 serves as the hub node of the high-voltage power supply, and reasonably distributes the electrical energy output by the battery module 200 to the vehicle driving system, the charging system, the air conditioner compressor and other high-voltage electrical equipment.

[0080] Referring to Figure 8 The power distribution box 400 includes a box body 410 and a box cover 420, and the box cover 420 is sealed on the box body 410 to realize the sealing of the box body 410.

[0081] The bottom wall of the box body 410 is provided with at least two support columns 411; the box cover 420 is provided with a receiving groove 421, and the at least two support columns 411 pass through the box cover 420 and extend into the receiving groove 421. It should be understood that the number of support columns 411 can be two, three or even more. When the number of support columns 411 is three, the three support columns 411 form a triangle, so that the connection stability of the box body 410 and the box cover 420 can be improved.

[0082] The receiving groove 421 is provided with a support block 430, the support block 430 is connected with the at least two support columns 411 through a third fixing member 440, and the top surface of the support block 430 away from the at least two support columns 411 is connected with the box cover 110 of the battery box body 100. It should be noted that the third fixing member 440 can also simultaneously connect the box cover 110, the support block 430 and the support column 411.

[0083] In this way, the box body 410 and the box cover 420 have the support column 411, which can provide additional support for the box cover 420. In addition, the receiving groove 421 is provided with a support block 430 with a large area, which can improve the contact area between the box cover 420 and the box cover 110, and avoid forming a gap between the box cover 420 and the box cover 110 at the position of the receiving groove 421. In this way, the support column 411 and the large-area support block 430 form a multi-level support network, and the stepping pressure is dispersed to the overall structure of the box body 410, avoiding plastic deformation caused by local stress concentration. At the same time, the cooperation of the support column 411 and the large-area support block 430 can also form a self-anti-stepping design of the distribution box 400 to prevent the distribution box 400 from being stepped and deformed.

[0084] In some embodiments, please refer to Figure 3 The second accommodating chamber 134 is also provided with two support brackets 500, and the two support brackets 500 are arranged on the two sides of the distribution box 400 along the second direction. The support bracket 500 includes a first support member 510, two second support members 520 and two third support members 530. The two second support members 520 are arranged on the two sides of the first support member 510 along the first direction and are perpendicular to the first support member 510.

[0085] Two third support members 530 are connected with the corresponding second support members 520 respectively, and the third support members 530 are parallel to the first support members 510. One of the third support members 530 is fixedly connected with the bottom wall of the box body 130, and the other third support member 530 is fixedly connected with the adjacent second support beam 132. In this way, the support bracket 500 forms a Chinese character 'jie' shape, and the Chinese character 'jie' shape geometry forms a multi-directional stress frame. The stepping load is conducted to both sides through the first support members 510, so as to avoid stress concentration in the middle of the box cover 420, improve the overall bending stiffness, and thus improve the anti-stepping capability of the distribution box 400 itself. At the same time, the larger contact area between the first support members 510 and the box cover 420 is used to make the pressure distribution more uniform, and significantly reduce the risk of local indentation of the box cover 420.

[0086] Further, the top surface of each support bracket 500 is provided with a second buffer layer 540. For example, the top surface of the first support member 510 is provided with the second buffer layer 540, and the area of the second buffer layer 540 can be less than or equal to the area of the first support member 510. The second buffer layer 540 (such as silica gel or foamed material) absorbs instantaneous impact energy through elastic deformation, and reduces the stress transmitted to the box cover 420.

[0087] The application further provides a vehicle comprising the battery pack 1000 described in any of the above embodiments; at least part of the box cover 110 of the battery pack 1000 constitutes a floor of the vehicle.

[0088] In view of the fact that the vehicle comprises the battery pack 1000 described in any of the above embodiments, the vehicle has the structure and advantages of the battery pack 1000, and thus the application will not be described in more detail.
