DETAILED DESCRIPTION

[0021] In the field of new energy storage, PACK refers to automotive battery packs, industrial and commercial energy storage battery packs, and household energy storage battery packs, including the battery system and battery packaging structure. The high-current terminals of the PACK are responsible for the electrical connection between the battery system and external systems. However, in related technologies, the high-current terminals of the PACK are often directly fixed to the conductive parts of the battery system, such as aluminum bars. During production, assembly, and subsequent use, this can easily cause unstable connection materials and current short circuits, affecting electrical transmission. Furthermore, the PACK box lacks handles, which makes manual handling in scenarios where lifting equipment is not available.

[0022] In view of this, the present application proposes a PACK structure, including a PACK high-current terminal connection structure and a PACK box handle structure.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, the present application discloses a PACK high-current terminal connection structure, which is located in a PACK box 6 and includes: a pressure plate 1, which is fixed in the PACK box 6 and contacts the PACK battery 5; an insulating fixing plate 2, which is fixed on the pressure plate 1; and a conductor part 3, which is fixed on the insulating fixing plate 2, connected to the high-current terminal 4, and contacts the PACK battery 5.

[0025] The pressure plate 1 can be fixed to the limiting structure in the PACK box 6 by screws to achieve compression of the PACK battery 5. There are two high-current terminals 4, namely the positive and negative wires. An insulating fixing plate 2 is used to prevent short circuits that may occur when the positive and negative wires are fixed to the conductor part 3. The insulating fixing plate 2 is provided with openings and nuts that match the conductor part 3 for connection and fixation. The conductor part 3 is fixed to the insulating fixing plate 2, connected to the high-current terminal 4, and in contact with the PACK battery 5 to achieve current transmission. It is preferably made of aluminum or other metal materials with strong conductivity.

[0026] The high-current terminal 4 is fixedly connected to the conductor part 3 , and the conductor part 3 is fixed by the insulating fixing plate 2 connected to the pressing plate 1 , thereby enhancing the overall connection stability.

[0027] Further, if Figure 2 As shown, the pressing plate 1 is provided with a notch, and the insulating fixing plate 2 is fixed at the notch of the pressing plate 1 .

[0028] The notch acts as a stop during assembly. When the pressure plate 1 contacts and presses against the insulating fixing plate 2, the notch precisely aligns with a specific portion of the insulating fixing plate 2, ensuring it remains in the correct position without shifting or sliding. This precise stop design significantly improves assembly accuracy and efficiency.

[0029] The notch in the pressure plate 1 also provides space for the insulation fixing plate 2 to be assembled. The notch in the pressure plate 1 provides a suitable slot or gap for the insulation fixing plate 2, allowing it to be easily and securely installed. This not only improves assembly convenience but also further enhances the insulation performance of the device.

[0030] The integrated design of the pressure plate 1 and its notch ensures connection stability. Whether it's the connection between the pressure plate 1 and adjacent components, or the fixation between the insulating fixing plate 2 and the conductor 3, the presence of the notch in the pressure plate 1 ensures a more secure and reliable connection. This stability is not only evident in the static assembly state, but also maintains a good connection even when subjected to external forces such as vibration and impact during operation, ensuring the normal operation and safety of the PACK.

[0031] Furthermore, the notch of the pressing plate 1 is close to the top of the PACK box 6 and is symmetrical along the vertical center line of the pressing plate 1 .

[0032] The four sides and bottom of the PACK battery 5 are in contact with the PACK box 6. Therefore, the notch of the pressure plate 1 is close to the top of the PACK box 6 to ensure that the conductor part 3 is in contact with the top of the battery. The notch is symmetrical along the vertical center line of the pressure plate 1, so that the stresses on the positive and negative wires during the production and assembly process can be more easily offset.

[0033] like Figures 1 to 3 As shown, in one embodiment, the insulating fixing plate 2 includes a central portion 21 and an edge portion 22 , the central portion 21 is located in the notch, and the edge portion 22 is located outside the notch and fixedly connected to the pressing plate 1 .

[0034] The edge portion 22 can be connected to the pressure plate 1 via screws to ensure the stability of the connection with the insulating fixing plate 2. A limit hole is provided on the side of the center portion 21 that contacts the conductor portion 3 to facilitate the fixation of the conductor portion 3. The limit hole passes through the insulating fixing plate 2 and has a built-in nut for further fixation. This makes the thickness of the center portion 21 slightly larger than the edge portion 22, and the pressure plate 1 needs to reserve a gap to accommodate the required space for assembly.

[0035] like Figure 1 As shown, in one embodiment, the conductor portion 3 includes a first conductor 31 and a second conductor 32 perpendicular to each other. The first conductor 31 is fixed on the insulating fixing plate 2 and connected to the high-current terminal 4 , and the second conductor 32 is in contact with the PACK battery 5 .

[0036] The first conductor 31 and the second conductor 32 can be formed by bending the originally straight conductor part 3. The first conductor 31 is fixed in the limiting hole by screws and nuts to ensure the stability of the connection; the second conductor 32 is welded above the PACK battery 5 to ensure that the current is conducted to the high-current terminal 4 through the conductor part 3.

[0037] like Figure 4As shown, the present application further discloses a PACK integrated handle 7, which is concave and located on two opposite sides of the outside of the PACK box 6, and can be applied to the PACK box 6 of the aforementioned PACK high-current terminal connection structure.

[0038] The integrated handle 7 of the PACK is concave, eliminating the need for an additional external handle structure, reducing space requirements and meeting the application scenarios of the PACK. In addition, this handle does not affect the power supply of the battery of the PACK box 6.

[0039] Furthermore, the top surface 71 of the recess of the PACK integrated handle 7 is inclined.

[0040] The inclined design of the top surface 71 of the recess provides a clear grip point and enhances friction. The angle changes with the force applied, allowing the operator to complete the task more quickly and accurately, thereby improving handling efficiency. This ensures safe handling and reduces the risk of the PACK slipping during handling, making manual handling more convenient in locations where lifting equipment is not available or difficult to reach.

[0041] The above is a detailed introduction to a PACK structure provided by an embodiment of the present invention. The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, the present invention can also be improved and modified in several ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
