Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to an integrated battery pack structure. Background Art

[0002] With the rapid development of the new energy vehicle industry, the performance, safety, and space utilization of power battery packs, as core components, have become key constraints in vehicle design. Traditional battery packs are typically mounted as a separate rigid shell under the vehicle floor via brackets. This structure has significant drawbacks: complex layers lead to low space utilization, a large amount of non-energy storage materials (such as the vehicle body, brackets, and mounting clearances) squeeze the Z-axis space of the vehicle body, and maintenance is inconvenient. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] An integrated battery pack structure includes a box body, an upper cover, an inspection cover, a seat mounting beam and an electrical component mounting frame. The box body with an open top is used to install the battery pack. The upper cover is arranged at the top opening of the box body. An inspection port is provided on the upper cover. The upper cover of the inspection port is provided with an inspection cover. Two sets of parallel seat mounting beams are fixed on the top of the upper cover. An inwardly concave installation cavity is provided at the bottom of the box body, and multiple electrical component mounting frames are provided in the installation cavity.

[0006] In this battery pack structure, the upper cover replaces the vehicle body floor structure, making the vehicle structure simpler and making full use of the Z-direction space of the vehicle. In addition, by arranging seat mounting beams and center console mounting beams on the upper cover, the seats and center console of the vehicle can be installed above the upper cover. Through the setting of the inspection port, the BMS and electrical components inside the battery pack can be quickly inspected without disassembling the battery pack. The three-in-one electrical components of the vehicle are installed in the installation cavity through the electrical component mounting rack, and the important three-in-one electrical components of the vehicle are integrated into the whole package, which has a high degree of integration and saves space in the vehicle.

[0007] Preferably, a plurality of mounting lugs are provided at two opposite ends of the box body.

[0008] Preferably, the edge of the upper cover is provided with a flange.

[0009] Preferably, a vehicle body sealing gasket is provided on the flange.

[0010] Preferably, a center console mounting beam is fixed to one of the groups of seat mounting beams.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This battery pack structure greatly simplifies the vehicle body design, effectively utilizes the vehicle's Z-direction space, and increases maintenance convenience. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of this application, "plurality" means two or more, unless otherwise expressly specified or limited.

[0019] See Figure 1 and Figure 2 This embodiment discloses an integrated battery pack structure, including a box body 1, an upper cover 2, an inspection cover 3, a seat mounting beam 4, an electrical component mounting frame 5, a center console mounting beam 6, a mounting ear 7 and a vehicle body sealing gasket 8.

[0020] The box body 1 with an open top is used to install the battery pack. A plurality of mounting lugs 7 are provided at the two opposite ends of the box body 1, and the battery pack structure is fixed to the vehicle body through the mounting lugs 7; the number of mounting lugs 7 can be 4, 6, 8, 10, etc., and the number of mounting lugs 7 is adapted according to the quality of the battery pack. In this embodiment, the box body 1 is provided with 6 mounting lugs 7, that is, 3 mounting lugs 7 are provided at each end. The material of the mounting lugs 7 can be high-strength stainless steel, or it can be a profile aluminum alloy or other materials.
