[0057] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0058] Figures 1 to 3 A battery compartment 100 according to the present invention is shown. The battery compartment 100 includes a plurality of compartment panel assemblies 110, a front compartment panel assembly 120, a battery rack 130, and a sealing ring. The compartment panel assembly 110 includes an outer panel 111, an inner panel 112, and a first reinforcing member 113. The first reinforcing member 113 is disposed between the outer panel 111 and the inner panel 112 and is respectively connected to the outer panel 111 and the inner panel 112. The front compartment panel assembly 120 includes a front panel 121 and a sealing plate 122. The front compartment panel assembly 120 and the plurality of compartment panel assemblies 110 at least partially form a compartment cavity 101. The front panel 121 has a compartment opening 123 for installing batteries into the compartment cavity 101. The sealing plate 122 is connected to the front panel 121 by fasteners 128. The battery rack 130 is disposed inside the battery compartment 100 and connected to the compartment panel assembly 110. The battery rack 130 is used to fix the batteries. The sealing ring is located at the opening 123 and between the front panel 121 and the sealing plate 122, with the sealing ring abutting against the sealing plate 122.

[0059] According to the present invention, the battery compartment 100 forms a double-layer side structure through the arrangement of the compartment body plate assembly 110 and the front compartment plate assembly 120. This structure has high strength and is not easily deformed, especially the compartment opening 123, thus ensuring the sealing performance of the opening 123. Furthermore, the sealing plate 122 is fixed to the front panel 121 by fasteners 128 and pressed against the sealing ring, thereby sealing the compartment opening 123 of the front panel 121. The sealing plate 122 will not deform due to the force applied to the compartment body plate assembly 110, thus maintaining a sealed connection to the compartment opening 123. This makes the sealing performance of the battery compartment 100 more stable, prevents leakage of the insulating medium, and improves safety.

[0060] Optionally, refer to Figure 1 and Figure 2 A heat insulation cavity 114 is formed between the inner panel 112 and the outer panel 111. The heat insulation cavity 114 is filled with heat insulation material 115, so that the compartment panel assembly 110 can insulate the compartment cavity 101, making the battery inside the compartment cavity 101 less susceptible to the effects of external temperature changes. Optionally, heat insulation material 115 can also be arranged between the front panel 121 and the sealing plate 122, so that heat insulation can be formed at the front compartment panel assembly 120, further reducing the impact of external temperature changes on the battery inside the compartment cavity 101.

[0061] Optionally, the thermal insulation material 115 can be polyurethane, thermal insulation cotton, or other materials, and preferably fireproof and thermal insulation materials 115 such as polyimide foam.

[0062] Reference Figure 2 Optionally, the first reinforcing member 113 is constructed as a square tube, and the first reinforcing members 113 are arranged at intervals along the height direction Z or the horizontal direction of the battery compartment 100 (in this embodiment, the first reinforcing members 113 are arranged at intervals along the height direction Z), thereby improving the structural strength of the compartment plate assembly 110 and reducing the impact of deformation on the sealing performance of the battery compartment 100. Optionally, the spacing between the first reinforcing members 113 between the outer plate 111 and the inner plate 112 is configured to be 350mm to 450mm, so that the compartment plate assembly 110 has good structural strength. Preferably, the spacing between the first reinforcing members 113 is 400mm, so that the battery compartment 100 is not easily deformed when the compartment cavity 101 is filled with coolant.

[0063] Regarding the battery compartment 100 according to one embodiment of the present invention as a whole, referring to... Figure 1 and Figure 2The battery compartment 100 also includes a base 140, a top plate assembly 141, and four uprights 142. Along the height direction Z of the battery compartment 100, the top plate assembly 141 is spaced apart from the base 140. The upper ends of the uprights 142 are connected to the top plate assembly 141, and the lower ends of the uprights 142 are connected to the base 140. The four uprights 142 are respectively arranged at the four corners of the base 140 and the four corners of the top plate assembly 141. The uprights 142, the inner plate 112, the front panel 121, the top plate assembly 141, and the base 140 form the compartment cavity 101, forming the overall structure of the battery compartment 100 for accommodating and installing batteries. Specifically, the battery compartment 100 includes three compartment panel assemblies 110 and a front compartment panel assembly 120 surrounding to form the side portion of the battery compartment 100, so that the side portion of the battery compartment 100 has a double-layered reinforced structure, which is structurally stable and not easily deformed by external forces in the transportation, hoisting or use environment, so as not to affect the sealing of the compartment opening 123.

[0064] Optionally, refer to Figure 2 The top plate assembly 141 includes an inner top plate 145, an outer top plate 146, and a second reinforcing member 147. Along the height direction Z, the inner top plate 145 is located below the outer top plate 146, and the inner top plate 145 is connected to the outer top plate 146, forming a cavity with it. The second reinforcing member 147 is disposed in the cavity and connected to the inner top plate 145, thereby ensuring sufficient structural strength for the top plate assembly 141 and preventing deformation of the top plate assembly 141 that could affect the sealing performance of the battery compartment 100. Specifically, the inner top plate 145 has upward-folded edges around its perimeter, allowing it to better fit against the bottom surface of the outer top plate 146 and form a cavity structure, resulting in better sealing.

[0065] In addition, the second reinforcing member 147 can also be constructed as a square tube. The second reinforcing member 147 extends along the width direction D2 and is arranged at intervals along the length direction D1, which can effectively enhance the structural strength of the top plate assembly 141.

[0066] Optionally, the top plate assembly 141 further includes an oil inlet 143, which is disposed on the inner top plate 145 and communicates with the compartment cavity 101, for injecting an insulating medium into the compartment cavity 101. The top plate assembly 141 also includes an explosion vent 144 for discharging the high-pressure medium in the compartment cavity 101, thereby improving the safety of the battery compartment 100.

[0067] Optionally, refer to Figure 2The two sides of the inner panel 112 are respectively connected to two adjacent columns 142. The two sides of the outer panel 111 are respectively connected to two adjacent columns 142. The top edges of both the inner panel 112 and the outer panel 111 are connected to the top inner panel 145. The bottom edges of both the inner panel 112 and the outer panel 111 are connected to the base 140, making the connection of the compartment panel assembly 110 stable and providing good sealing.

[0068] The top edge of the front panel 121 is connected to the inner top panel 145, the bottom edge of the front panel 121 is connected to the base 140, and the two sides of the front panel 121 are respectively connected to two columns 142 adjacent to the front panel 121, so that the front panel 121 has a stable connection.

[0069] Optionally, the inner panel 112, front panel 121, base 140, top panel, and column 142 are continuously welded together using CO2 shielded welding. By adjusting the welding process, welding deformation can be effectively controlled, thereby ensuring good sealing of the hopper cavity 101 and preventing leakage of the insulating medium inside the hopper cavity 101. The outer panel 111, base 140, top inner panel 145, front panel 121, and column 142 are welded together using laser welding, which enhances the sealing and provides an aesthetically pleasing result.

[0070] Specifically, regarding the structure of the front compartment panel assembly 120.

[0071] Reference Figure 1 and Figure 2 The front panel 121 is provided with a bent edge 124. The bent edge 124 is provided around the edge of the compartment opening 123 and protrudes from the compartment opening 123 along the length direction D1. This makes the bent edge 124 and the inner wall of the compartment opening 123 form an annular sealing groove 125 for installing the sealing ring. This can securely install the sealing ring and prevent it from easily detaching from the front panel 121, thereby ensuring the stability of the sealing performance of the battery compartment 100.

[0072] like Figure 1 As shown, the front panel 121 has two openings 123, and the front compartment panel assembly 120 includes two sealing plates 122 corresponding to the two openings 123, which are connected together. Multiple fasteners 128 on the sealing plates 122 are spaced apart along the edges of the openings 123. By using a one-to-one sealing method between the sealing plates 122 and the openings 123, a uniform clamping force is applied around each opening 123, further ensuring the airtightness of the battery compartment 100 at the opening 123. It is understood that any technical solution where the front panel 121 has more than two openings 123, or the front compartment panel assembly 120 includes more than two sealing plates 122, should be within the protection scope of this utility model.

[0073] Optionally, the sealing plate 122 is provided with an observation window 126 for observing the situation inside the compartment cavity 101.

The observation window sealing plate 127 is connected to the sealing plate 122 via a sealing element to seal the observation window 126. The observation window 126 can also be constructed with the same structure as the compartment opening 123, and a sealing ring of a corresponding size can be installed to achieve a sealed connection with the observation window sealing plate 127, preventing leakage of the insulating medium.

[0074] Specifically, regarding the structure of battery holder 130.

[0075] Reference Figure 2 The battery rack 130 includes a vertical beam 131, a guide rail 132, and a fixing plate 133. The vertical beam 131 extends along the height direction Z of the battery compartment 100 and connects to the base 140 and the top plate. Specifically, the top end of the vertical beam 131 connects to the inner top plate 145, and the bottom end connects to the base 140. The guide rail 132 extends perpendicularly to the side wall where the upper compartment opening 123 of the front panel 121 is located. In other words, the guide rail 132 extends along the length direction D1 and is connected to the vertical beam 131. The fixing plate 133 is connected to the vertical beam 131 and is provided with fixing holes 134 for fixing the battery with fasteners 128, thereby achieving battery installation.

[0076] Reference Figure 2 The battery compartment 100 includes two battery racks 130, which are spaced apart along the width direction D2, allowing connection to both sides of the battery. Guide rails 132 support individual battery cells (or battery packs). Each battery rack 130 includes multiple guide rails 132, which are spaced apart along the height direction Z, allowing multiple batteries to be installed along the height direction Z. This also ensures sufficient contact between the batteries within the compartment cavity 101 and the insulating medium, facilitating heat dissipation and insulation of the batteries.
