DETAILED DESCRIPTION
[0023] The present application provides a battery pack of a vehicle and a vehicle comprising the same. The battery pack of the vehicle and the vehicle comprising the same of the present application will be described in detail below with reference to the accompanying drawings. The features in the following embodiments and implementation examples can be combined with each other without conflict.
[0024] Figure 1 A partial structure schematic diagram of one embodiment of the battery pack 10 of the vehicle of the present application is shown. As shown in the figure, Figure 1 The battery pack 10 of the vehicle comprises a battery box 11, a controller box 12 independent of the battery box 11, a power battery, and a domain controller electrically connected to the power battery. The power battery is accommodated in the battery box 11, the domain controller is accommodated in the controller box 12, and the battery box 11 and the controller box 12 are in communication. One end of the battery box 11 comprises a mounting surface 13. The controller box 12 comprises a docking surface 14. The docking surface 14 is fixedly connected to the mounting surface 13. A sealing element 15 is arranged between the docking surface 14 and the mounting surface 13.
[0025] In order to realize the communication between the battery box 11 and the controller box 12, one end of the battery box 11 is designed with the mounting surface 13, and the controller box 12 is correspondingly designed with the docking surface 14. The docking surface 14 and the mounting surface 13 are fixedly connected together by means of bolt connection, buckle connection, etc., thereby forming an integral structure.
[0026] In order to ensure the dryness, dust prevention, and water prevention of the internal environment of the battery pack 10, and prevent the influence of external factors such as electromagnetic interference on the internal components, the sealing element 15 is arranged between the mounting surface 13 and the docking surface 14. The sealing element 15 can effectively fill the small gap between the mounting surface 13 and the docking surface 14, and provide reliable sealing effect.
[0027] In some embodiments, by arranging the sealing element 15 between the docking surface 14 and the mounting surface 13, the sealing property of the connection between the battery box 11 and the controller box 12 in the battery pack 10 can be improved.
[0028] In some embodiments, the sealing element 15 comprises sealing foam.
[0029] The sealing foam is a porous, soft and elastic material with good sealing performance and buffering capacity. The sealing foam can effectively fill the small gap between the abutting surface 14 and the mounting surface 13 and provide a lasting sealing effect. The porous structure of the sealing foam allows the foam to absorb and distribute stress caused by vibration or temperature changes, thereby maintaining the integrity of the seal.
[0030] Using sealing foam as the material of the sealing member 15 can improve the sealing performance of the connection between the battery box 11 and the controller box 12, prevent moisture, dust and other contaminants from entering the battery pack interior, and ensure the safe and stable operation of the battery pack 10.
[0031] In some embodiments, the sealing foam is a silica gel foam material.
[0032] The silica gel foam material combines the excellent performance of silica gel and the sealing capacity of foam, allowing the sealing member 15 to maintain its sealing performance under a wider range of environmental conditions. Using silica gel foam material as the raw material of the sealing foam can further improve the durability and reliability of the sealing member 15, prolong its service life, and reduce maintenance costs caused by sealing failure.
[0033] Figure 2 The battery pack 10 of the vehicle is shown. Figure 1 The partial structure diagram of the battery pack 10 of the vehicle is shown.
[0034] The battery box 11 includes a battery box body 111 and a mounting plate 112 connected to one end of the battery box body 111. The power battery is housed in the battery box body 111, and the mounting plate 112 includes a mounting main plate 113 and an extension plate 114, and the mounting main plate 113 includes a mounting surface 13. The extension plate 114 extends from the edge of the mounting plate 112 towards the direction of the battery box body 111 and is fixedly connected to the battery box body 111.
[0035] The battery box body 111 is designed with sufficient space and structural strength to safely accommodate the power battery. The mounting plate 112 is used to connect the battery box 11 with the controller box 12. The mounting plate 112 is composed of the mounting main plate 113 and the extension plate 114.
[0036] The mounting main plate 113 is the main part of the mounting plate 112 and is designed with the mounting surface 13. The mounting surface 13 is a flat surface used for fixed connection with the controller box 12.
[0037] The extension plate 114 extends from the edge of the mounting plate 112 in the direction of the battery box body 111 and is fixedly connected with the battery box body 111. The extension plate 114 can enhance the connection strength between the mounting plate 112 and the battery box body 111, while providing additional support and stability. In this way, it helps to ensure the overall structural stability of the battery box 11 during vehicle operation, and prevents damage caused by vibration or impact.
[0038] By setting the battery box body 111 and the mounting plate 112, not only the safe accommodation space of the power battery is ensured, but also the overall performance and reliability of the battery pack 10 are provided with strong guarantee.
[0039] In some embodiments, the mounting surface 13 and the mating surface 14 have the same profile shape.
[0040] In order to ensure the close connection and accurate alignment between the battery box 11 and the controller box 12, the mounting surface 13 and the mating surface 14 are designed to have the same profile shape. In this way, the mounting surface 13 and the mating surface 14 can completely match when connected, reducing the gap or misalignment problem caused by shape mismatch. By ensuring that the profile shape of the mounting surface 13 and the mating surface 14 is the same, the stability and reliability of the connection can also be improved, and the overall structural strength of the battery pack 10 can be enhanced.
[0041] In some embodiments, the seal 15 has the same profile shape as the mounting surface 13 and the mating surface 14.
[0042] In order to provide effective sealing effect, the seal 15 is designed to have the same profile shape as the mounting surface 13 and the mating surface 14. In this way, it is ensured that the seal 15 can closely fit between the mounting surface 13 and the mating surface 14, filling any small gap between the mounting surface 13 and the mating surface 14, thereby preventing moisture, dust or other contaminants from entering the inside of the battery pack 10. By matching the profile shape of the seal 15 with the profile shape of the mounting surface 13 and the mating surface 14, the durability and reliability of the seal 15 can also be improved, ensuring that it can maintain effective sealing effect during long-term use.
[0043] In some embodiments, the seal 15 is attached to the edge of the mating surface 14 and the mounting surface 13.
[0044] The seal 15 is precisely attached to the edge of the abutment surface 14 and the mounting surface 13. In this way, it is ensured that the seal 15 can effectively form a continuous sealing barrier around the periphery of the abutment surface 14 and the mounting surface 13. This helps to minimize the risk of sealing failure due to unevenness or small gaps in the abutment surface 14 and the mounting surface 13. The edge attachment of the seal 15 can ensure that when the battery box 11 and the controller box 12 are connected, the seal 15 can be tightly compressed between the abutment surface 14 and the mounting surface 13, thereby providing more reliable and durable sealing effect.
[0045] Figure 3 A partial structural schematic diagram of the battery pack 10 of the vehicle is shown. Figure 1 A partial structural schematic diagram of the battery pack 10 of the vehicle is shown.
[0046] The abutment surface 14 is recessed to form a groove, and the seal 15 is arranged in the groove.
[0047] The design of the groove highlights the edge of the abutment surface 14, ensuring that the seal 15 can be precisely positioned and fixed between the abutment surface 14 and the mounting surface 13. At the same time, the groove provides space for wiring between the domain controller and the power battery.
[0048] Figure 4 A partial structural schematic diagram of the battery pack 10 of the vehicle is shown. Figure 1 A partial structural schematic diagram of the battery pack 10 of the vehicle is shown.
[0049] Figure 5 A partial structural schematic diagram of the battery pack 10 of the vehicle is shown. Figure 1 A partial structural schematic diagram of the battery pack 10 of the vehicle is shown.
[0050] The controller box 12 includes a positioning pin 121, and the seal 15 includes a positioning hole 151 corresponding to the position of the positioning pin 121, and the positioning pin 121 passes through the positioning hole 151.
[0051] The controller box 12 is provided with at least one positioning pin 121. The positioning pin 121 is a protruding cylinder or similar shape. In some embodiments, the position and number of the positioning pin 121 are determined according to the design of the seal 15 and the abutment surface 14.
[0052] The positioning pin 121 is mainly used to provide a precise reference point to ensure that the seal 15 can be correctly aligned and positioned during installation.
[0053] The seal 15 is provided with a positioning hole 151 corresponding to the position of the positioning pin 121 on the controller box 12. The shape and size of the positioning hole 151 match the positioning pin 121 to ensure that the positioning pin 121 can smoothly pass through the positioning hole 151 and fix the seal 15 in the correct position.
[0054] The positioning hole 151 is designed to enable the seal 15 to be automatically aligned during installation, reducing errors and inconvenience caused by manual alignment.
[0055] When the controller box 12 is connected to the battery box 11, the positioning pin 121 on the controller box 12 passes through the positioning hole 151 on the seal 15 and connects with the mounting surface 13 on the battery box 11. In this way, the seal 15, the controller box 12 and the battery box 11 are accurately aligned and fixed.
[0056] The cooperation of the positioning pin 121 and the positioning hole 151 also provides additional stability and reliability, preventing the seal 15 from being displaced or falling off due to uneven force or vibration during connection.
[0057] The design of the positioning pin 121 and the positioning hole 151 also greatly improves the convenience of installing and maintaining the seal 15. The installer can more easily place the seal 15 in the correct position and fix it through the cooperation of the positioning pin 121 and the positioning hole 151, without the need for additional fixing devices or tools.
[0058] When the seal 15 needs to be replaced or maintained, the design of the positioning pin 121 and the positioning hole 151 also makes it easier to access and disassemble the seal 15, thereby reducing maintenance costs and time.
[0059] The seal 15 is also provided with a threaded hole 16 for the bolt to pass through, so that the seal 15 is pressed tightly between the mounting surface 13 and the abutting surface 14.
[0060] The application also provides a vehicle, comprising: a high-voltage electrical component, a low-voltage electrical component, and a battery pack 10 as described above.
