Description

Technical Field

[0001] This utility model relates to the field of battery box technology, specifically a liquid-cooled plate box structure. Background Technology

[0002] With the continuous development of the automotive industry, gasoline or diesel-powered vehicles are gradually being replaced by electric vehicles. As the energy storage device of electric vehicles and the sole power source driving them, the battery pack's energy storage capacity and safety factor directly determine the performance of electric vehicles. During battery use, heat is generated inside the battery cells, and this heat accumulation can easily lead to fires, explosions, and other phenomena.

[0003] Currently, battery boxes in electric vehicles generally have a liquid cooling structure, which is mostly achieved by adding a liquid cooling plate at the bottom of the box to cool the battery. However, the liquid cooling plate is mostly fixed to the box by welding. When the internal pipeline of the liquid cooling plate malfunctions or needs to be inspected and maintained, it is inconvenient to disassemble and install the liquid cooling plate, which brings inconvenience to the actual work. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a liquid-cooled plate box structure.

[0005] The present invention proposes a liquid-cooled plate box structure, including a liquid-cooled plate and a box enclosure. The box enclosure includes two first baffles and two second baffles arranged opposite to each other, and adjacent first baffles and second baffles are connected to each other to form an enclosure.

[0006] The upper surface of the liquid cooling plate is equipped with a limit strip. The bottom of the first baffle and the second baffle are both provided with limit slots that are adapted to the limit strip. The first baffle and the second baffle are inserted into the limit strip through the limit slots and locked with fasteners.

[0007] Preferably, the limiting stop includes a first stop and a second stop. There are two first stopes, each corresponding to one of the two first baffles. The first baffles are inserted into the first stopes. There are two second stopes, each corresponding to one of the two second baffles. The second baffles are inserted into the second stopes, and the two end faces of the second baffles are tightly fitted to the inner side faces of the adjacent first baffles.

[0008] Preferably, the limiting stop is T-shaped with the T-shaped head facing upwards, and the limiting slot is a T-shaped groove adapted to the limiting stop, with both ends of the T-shaped groove being open.

[0009] Preferably, the fastener includes a stop block and a screw. The stop block is slidably mounted on the upper end face of the liquid cooling plate and located on the side of the first baffle. An insert block is installed on the opposite side of the stop block and the bottom limiting slot opening of the first baffle. The insert block is adapted to the limiting slot, and the stop block drives the insert block to slide into the limiting slot and is fixed by the screw.

[0010] Preferably, the upper surface of the liquid cooling plate is equipped with guide blocks symmetrically distributed on both sides of the first baffle. The bottom of the baffle is provided with a guide groove that matches the guide block, and the side of the guide groove closest to the first baffle is open. The baffle is inserted into the guide block through the guide groove, and the baffle is connected and locked to the guide block by screws.

[0011] Preferably, the stop is L-shaped, and the two right-angled sides of the outer right angle of the L-shape are respectively attached to the upper end surface of the liquid cooling plate and the side of the first stop.

[0012] The liquid-cooled plate box structure proposed in this utility model has the following beneficial effects:

[0013] This utility model achieves quick assembly of the first and second baffles with the liquid cooling plate by installing multiple limiting strips on the liquid cooling plate and inserting them into the corresponding limiting strips. This facilitates the rapid assembly and forming of the enclosure. The T-shaped structure design of the limiting strips and limiting slots ensures a tight and stable assembly of the first and second baffles with the liquid cooling plate, which is then locked in place by a stop block. The overall structure is simple and facilitates the disassembly and assembly of the liquid cooling plate for inspection and maintenance, bringing convenience to practical work.

[0025] Please see Figure 1 A liquid-cooled plate enclosure structure includes a liquid-cooled plate 1 and an enclosure enclosure. The enclosure enclosure includes two first baffles 2 and two second baffles 3 arranged opposite to each other, and adjacent first baffles 2 and second baffles 3 are connected to each other to form an enclosure.

[0026] like Figure 1 and Figure 2 As shown, a limit stop 4 is installed on the upper end face of the liquid cooling plate 1. The bottom of the first baffle 2 and the second baffle 3 are provided with a limit slot 5 that is adapted to the limit stop 4. The first baffle 2 and the second baffle 3 are inserted into the limit stop 4 through the limit slot 5 and locked by fasteners.

[0027] The limiting strip 4 includes first strips on the left and right sides of the figure and second strips on the top and bottom sides of the figure. There are two first strips, each corresponding to two first baffles 2. The first baffles 2 are inserted into the first strips. There are two second strips, each corresponding to two second baffles 3. The second baffles 3 are inserted into the second strips, and the two end faces of the second baffles 3 are tightly fitted with the inner side faces of the adjacent first baffles 2.

[0028] Two second baffles 3 form a receiving channel on the upper end face of the liquid cooling plate 1, while two first baffles 2 block the openings on both sides of the receiving channel. With this design, the first baffles 2 and the second baffles 3 can be stably assembled by fixing the first baffles 2 to the liquid cooling plate 1 with fasteners, which is convenient for actual disassembly and replacement.

[0029] Specifically, such as Figure 1 As shown, the limiting stop 4 is T-shaped with the T-shaped head facing upwards. The limiting slot 5 is a T-shaped groove that matches the limiting stop 4, and both ends of the T-shaped groove are open. During disassembly and assembly, the two second baffles 3 are horizontally inserted into the corresponding second baffles through the limiting slots 5 at the bottom. Then, the first baffle 2 is horizontally inserted into the first baffle, so that the inner side of the first baffle 2 is in contact with the end face of the second baffle 3. At this time, the second baffle 3 is difficult to move laterally or longitudinally, while the first baffle 2 is difficult to move longitudinally. The first baffle 2 can then be fixed with fasteners, which can improve the overall assembly firmness.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, the fastener includes a stop block 6 and a screw. The stop block 6 is slidably mounted on the upper end face of the liquid cooling plate 1 and located on the side of the first baffle 2. An insert block 7 is installed on the opposite side of the stop block 6 and the opening of the bottom limiting slot 5 of the first baffle 2. The insert block 7 is adapted to the limiting slot 5, and the stop block 6 drives the insert block 7 to slide into the limiting slot 5 and is fixed by the screw. Through the insertion of the insert block 7 into the limiting slot 5, the stop block 6 blocks the openings on both sides of the first baffle 2 and also improves the assembly stability of the first baffle 2. Finally, it is locked by the screw.

[0031] Furthermore, such as Figure 4 As shown, guide blocks 8 are symmetrically distributed on both sides of the first baffle 2 on the upper end surface of the liquid cooling plate 1. The bottom of the baffle 6 is provided with a guide groove 9 that matches the guide block 8. The side of the guide groove 9 closest to the first baffle 2 is open. The baffle 6 is inserted into the guide block 8 through the guide groove 9. The baffle 6 is connected and locked to the guide block 8 by screws, which facilitates the stable and quick assembly of the baffle 6.

[0032] Furthermore, the stop 6 is L-shaped, and the two right-angled sides of the outer right angle of the L-shape are respectively attached to the upper end face of the liquid cooling plate 1 and the side of the first baffle 2, which can improve the installation stability of the first baffle 2.

[0033] In summary, the liquid-cooled plate housing structure proposed in this utility model, by installing multiple limiting strips 4 on the liquid-cooled plate 1, and by using the first baffle 2 and the second baffle 3 to insert with the corresponding limiting strips 4, can quickly assemble the first baffle 2, the second baffle 3 and the liquid-cooled plate 1, so as to facilitate the rapid assembly and forming of the housing enclosure. Through the T-shaped structure design of the limiting strips 4 and the limiting slots 5, the assembly of the first baffle 2, the second baffle 3 and the liquid-cooled plate 1 is tight and stable, and then locked and fixed by the stop block 6. The overall structure is simple and convenient for disassembling and assembling the liquid-cooled plate 1, so as to facilitate the inspection and maintenance of the liquid-cooled plate 1, bringing convenience to actual work.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
