[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-7 This utility model provides a technical solution: a PCAK battery housing that is easy to position and install, including a lower outer shell 1, an upper outer shell 2, a positioning block 3, a positioning groove 4, a mounting block 5, an external heat dissipation hole 6, a cooling fan 7, an internal heat dissipation hole 8, a lower support plate 9, an upper support plate 10, a lower fixing block 11, an upper fixing block 12, and a partition groove 13.

[0023] The lower outer shell 1 has a double-layer support structure inside. The double-layer support structure provides double-layer support for the battery pack through the lower support plate 9 and the upper support plate 10. The double-layer support structure includes the lower support plate 9. The front and rear surfaces of the lower support plate 9 are symmetrically provided with arc-shaped notches. The lower support plate 9 is connected to the lower fixing block 11 by bolts. The lower fixing block 11 is fixedly installed on the bottom surface of the lower outer shell 1. The bottom surface of the lower outer shell 1 is fixedly installed with the upper fixing block 12. The installation position between the upper fixing block 12 and the lower fixing block 11 is perpendicular. The upper fixing block 12 is an arc-shaped structure. The outer surface of the upper fixing block 12 engages with the arc-shaped notch on the surface of the lower support plate 9. The upper end of the upper fixing block 12 is connected to the upper support plate 10 by bolts. The height of the upper fixing block 12 is greater than the height of the lower fixing block 11. The upper surfaces of the lower support plate 9 and the upper support plate 10 are respectively fixedly installed with partition grooves 13. The partition grooves 13 are hollow cuboid structures with open upper surfaces. like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, when installing the battery using this device, insert the arc-shaped notches on the front and rear surfaces of the lower support plate 9 into the outer surface of the upper fixing block 12, push the lower support plate 9 downward until it contacts the surface of the lower fixing block 11, and fix the lower support plate 9 to the lower fixing block 11 with bolts to achieve the initial installation of the lower support plate 9. Place the PCAK battery cells or battery packs one by one into the partition grooves 13 on the surface of the lower support plate 9, ensuring that the batteries are in close contact with the inner wall of the partition grooves 13. Place the upper support plate 10 on the upper fixing block 12 and fix the upper support plate 10 to the upper fixing block 12 with bolts. Similarly, engage and fix the PCAK battery cells to the partition grooves 13 on the surface of the upper support plate 10. After completing the installation of the upper and lower battery layers, lead out the main positive and main negative wires of the battery pack and install terminal blocks at the wire lead-out ends for easy connection to external equipment later.

[0024] The lower outer shell 1 is a hollow cuboid structure with an open upper surface. An upper outer shell 2 is provided above the lower outer shell 1. The upper outer shell 2 is fitted onto the outer surface of the lower outer shell 1. There is an installation gap between the outer surface of the lower outer shell 1 and the inner surface of the upper outer shell 2. The upper outer shell 2 is a hollow cuboid. A square through hole with the same cross-section as the lower outer shell 1 is provided on the lower outer shell 1 and the upper outer shell 2. The positioning connection structure is provided on the surfaces of the lower outer shell 1 and the upper outer shell 2. The positioning connection structure assists the positioning connection between the lower outer shell 1 and the upper outer shell 2 through the positioning block 3 and the positioning groove 4. The positioning connection structure includes the positioning block 3, which is a long strip structure. The positioning block 3 is fixedly installed on the outer surface of the lower outer shell 1. The positioning block 3 is engaged with the inner wall of the positioning groove 4. The positioning groove 4 has a concave cross-section and is embedded and fixed on the outer surface of the upper outer shell 2. The lower end of the positioning groove 4 penetrates the lower surface of the upper outer shell 2. The positioning groove 4 and the positioning block 3 are connected by bolts. like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, after the battery is installed, the lower outer shell 1 and the upper outer shell 2 are connected. Holding the upper outer shell 2, the upper outer shell 2 is installed over the lower outer shell 1, so that the positioning block 3 on the outer surface of the lower outer shell 1 engages with the positioning groove 4 on the inner surface of the upper outer shell 2. Since the lower end of the positioning groove 4 penetrates the lower surface of the upper outer shell 2, the positioning block 3 can be directly guided into it without repeatedly adjusting the position of the upper outer shell 2, thus quickly completing the initial positioning. After the positioning block 3 is fully engaged with the bottom of the positioning groove 4, a bolt is used to pass through the preset bolt holes of the positioning groove 4 and the positioning block 3 to fix the positioning block 3 and the positioning groove 4, thereby ensuring the installation stability between the lower outer shell 1 and the upper outer shell 2 and avoiding installation misalignment. At the same time, an installation gap is formed between the outer surface of the lower outer shell 1 and the inner surface of the upper outer shell 2 for heat dissipation and airflow.

[0025] The surfaces of the lower outer shell 1 and the upper outer shell 2 are provided with heat dissipation structures. The heat dissipation structures dissipate heat from the internal components of the device through external heat dissipation holes 6 and internal heat dissipation holes 8. The heat dissipation structure includes a mounting block 5, which is trapezoidal in shape. The mounting block 5 is embedded and fixed on the front and rear surfaces of the upper outer shell 2. The surface of the mounting block 5 is provided with external heat dissipation holes 6, which are aligned with the mounting gap between the lower outer shell 1 and the upper outer shell 2. A cooling fan 7 is embedded and fixed on the side surface of the upper outer shell 2. The air outlet of the cooling fan 7 is located in the mounting gap between the lower outer shell 1 and the upper outer shell 2. An internal heat dissipation hole 8 is provided on one side of the cooling fan 7, which is provided through the side surface of the lower outer shell 1. like Figure 2 and Figure 7As shown, when it is necessary to dissipate heat inside the device, the cooling fan 7 is turned on. After the cooling fan 7 is turned on, the airflow is blown into the installation gap between the lower outer shell 1 and the upper outer shell 2 through the air outlet. The cold air from the outside is blown into the device from the inner heat dissipation hole 8 on the side surface of the lower outer shell 1, and the hot air in the installation gap is discharged to the outside through the outer heat dissipation hole 6 on the surface of the mounting block 5, thereby achieving heat dissipation inside the device.

[0026] Working principle: When using the PCAK battery case that facilitates positioning and installation, the positioning groove 4 on the inner surface of the upper outer shell 2 is engaged with the positioning block 3 on the outer surface of the lower outer shell 1 until the positioning groove 4 and the positioning block 3 are fully engaged, thereby assisting the connection between the upper outer shell 2 and the lower outer shell 1. Bolts are used to connect the lower outer shell 1 and the upper outer shell 2. At this time, an installation gap is formed between the lower outer shell 1 and the upper outer shell 2, which provides space for heat dissipation. The lower support plate 9 and the upper support plate 10 are installed inside the lower outer shell 1 to form a double-layer structure for the battery. The battery is limited by the partition groove 13 to prevent shaking. The heat inside the case enters the installation gap through the inner heat dissipation hole 8 of the lower outer shell 1, and is then discharged through the outer heat dissipation hole 6 of the mounting block 5 of the upper outer shell 2. The cooling fan 7 is started to blow air into the installation gap to accelerate air circulation and increase the overall practicality.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
