Description

Technical Field

[0001] This utility model relates to the field of battery pack structure technology, and in particular to a battery swapping battery pack structure. Background Technology

[0002] Battery swapping for electric vehicles has garnered widespread attention due to its rapid energy replenishment advantage. However, existing battery pack structures suffer from several shortcomings: traditional designs employ a top-discharge, bottom-charge scheme, resulting in a loose structure, large size, and excessive weight due to the use of a single metal material, making them inconvenient to carry and store; furthermore, the dispersed internal component layout leads to complex assembly and maintenance, high production costs, and negatively impacts user experience and promotion efficiency. To address these issues, there is an urgent need to develop a battery pack structure that, while ensuring structural strength, achieves a compact design, lightweight manufacturing, and modular assembly, thereby improving ease of use and reducing production costs. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, the present invention provides a battery swapping pack structure.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A battery swapping pack structure includes a battery module, a housing, a top cover assembly, and a bottom cover assembly. The battery module is disposed inside the housing. One end of the housing is connected to the top cover assembly, and the other end of the housing is connected to the bottom cover assembly.

[0006] The battery module includes a cell assembly, a bracket, and a PCB assembly. The bracket is disposed inside the housing, the cell assembly is disposed inside the bracket, there is a gap between the upper surface of the bracket and the top wall of the housing, and the PCB assembly is disposed within the gap.

[0007] Furthermore, a support column is provided above the bracket to support the gap.

[0008] Furthermore, the bracket includes an upper bracket and a lower bracket, which are pressed together.

[0009] Furthermore, the battery module also includes an insulating layer disposed between the upper bracket and the PCB assembly, covering the upper surface of the battery cell assembly.

[0010] Furthermore, the top left corner of the top cover assembly is provided with a charging socket hole and a discharging socket hole.

[0011] Furthermore, a handle is installed in the middle of the top cover assembly.

[0012] Furthermore, the bottom cover assembly has a charging socket hole 2 at the top center.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides a battery pack structure for battery swapping, which achieves a comprehensive improvement in battery pack performance through an innovative structural layout. In terms of structural design, a compact spatial arrangement is adopted, cleverly installing the PCB components in the gaps between the supporting structures. Combined with the upper and lower brackets' clamping connection, this significantly reduces the overall volume of the battery pack. Simultaneously, by rationally planning the wiring paths for the charging and discharging socket holes and fully utilizing the space on the sides of the supporting structures, the height of the battery pack is effectively reduced. Furthermore, the design using a combination of sheet metal and cast aluminum materials ensures structural strength while significantly reducing overall weight, making the battery pack easier to carry and replace.

[0017] This utility model provides a battery pack structure for battery swapping, which offers significant advantages in manufacturing and maintenance due to its modular construction. Standardized component design and pre-designed wiring space simplify the assembly process and greatly improve production efficiency. The easy-to-disassemble structure of each component greatly facilitates later maintenance and component replacement. This optimized design not only reduces production costs, including material consumption and labor costs, but also further reduces maintenance expenses by extending the lifespan of key components. A specially designed charging interface at the rear of the battery pack allows for direct insertion into a charging cabinet for automatic charging, eliminating the need for manual plugging and unplugging of charging cables, thus improving the convenience of battery swapping operations and creating favorable conditions for large-scale application.

Figure 1 As shown, the system includes a battery module 1, a housing 2, a top cover assembly 3, and a bottom cover assembly 4. The battery module includes a cell assembly 11, an upper bracket 12, a lower bracket 13, an insulating layer 14, a support column 15, and a PCB assembly 16. Figure 2 As shown, the battery cell assembly 11 is fixed inside the upper bracket 12 and the lower bracket 13. The upper bracket 12 and the lower bracket 13 can be pressed together to form a frame to protect the battery cell assembly 11. The PCB assembly 16 is located in the center area directly above the upper bracket 12. After being encapsulated, it is a cuboid and is fixed to the upper bracket 12 by screws.

[0027] An insulating layer 14 is provided above the upper bracket 12 to protect the cell assembly 11 and the PCB assembly 16. Support columns 15 are also provided above the upper bracket 12, spaced apart on the surface of the upper bracket 12, their installation positions avoiding the soldering area and main wiring paths of the PCB assembly 16. The top of the support columns 15 is flush with the upper surface of the PCB assembly 16, forming uniform support for the housing 2. The support columns 15 ensure that the battery module 1 remains stable and does not wobble after being installed in the housing 2. Furthermore, the design of the upper bracket 12, lower bracket 13, and support columns 15 during daily use can prevent damage to the cell assembly 11 in the event of vibration, impact, drop, or collision, effectively improving the safety performance of the battery pack.

[0028] The top cover assembly 3 has a charging socket hole 31 and a discharging socket hole 32 on its front side. The charging socket hole 31 and the discharging socket hole 32 are installed at the upper left top of the top cover assembly 3, making full use of the reserved space provided by the support column 15 and meeting the height requirements of the wiring harness at the end of the socket hole. A handle 33 is provided at the center of the front side of the top cover assembly 3 for daily lifting of the battery pack. The space on the back of the top cover assembly 3 is used for wiring harness routing and is equipped with reinforcing ribs to improve the structural strength of the top cover assembly.

The charging socket hole 2 41 is located at the center of the top of the bottom cover assembly 4, making full use of the reserved space provided by the support column 15 and meeting the height requirements of the wire harness at the tail of the charging socket hole 41. The space on the back of the bottom cover assembly 4 is used for wire harness routing, and it also adopts a reinforced rib design to improve the structural strength of the bottom cover assembly.

[0030] The housing 2 is used to connect the top cover assembly 3 and the bottom cover assembly 4. The left side of the housing 2 is connected to the top cover assembly 3 by screws, and the right side of the housing 2 is connected to the bottom cover assembly 4 by screws.

[0031] The housing 2 and the top cover assembly 3 are made of sheet metal, which is low in cost and high in strength. The bottom cover assembly 4 is made of cast aluminum, which is lightweight. This combination of materials ensures structural strength while achieving lightweight design.

[0032] The battery pack structure provided in this embodiment can be quickly installed by following these steps during manufacturing:

[0033] 1. First, assemble the battery module 1, the housing 2, the top cover assembly 3, and the bottom cover assembly 4 respectively;
