[0002] With the increasing number of new energy vehicles, the usage of battery packs is getting larger and larger. In order to improve the service life of the battery pack and increase the endurance of the battery pack, water-cooling channels are usually designed on the battery pack to take away the heat emitted by the battery pack when it is working, thereby increasing the service life of the battery pack. At present, the sealing of the water-cooling channels and the series plates of the battery pack are mostly welded, and welding defects may occur. Once the weld fails, the entire product will be repaired or scrapped. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a water-cooling plug for the water-cooling channel of a battery box in response to the current status of the existing technology.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: to provide a water-cooling plug for the water-cooling channel of a battery box, which is used to seal the end of the channel, comprising:

[0005] a main body block, which is detachably connected to the flow channel;

[0006] An extrusion block is movably disposed in the main body block, an extrusion space is formed between the main body block and the extrusion block, and a sealing ring is provided in the extrusion space;

[0007] When the main body block is inserted into the flow channel, the flow channel pushes the extrusion block to move on the main body block to reduce the width of the extrusion space and compress the sealing ring so that the sealing ring is pressed against the side wall of the flow channel.

[0008] In the above-mentioned water-cooling plug for the water-cooling channel of a battery box, the main body block includes two symmetrically arranged shells, which form an accommodating space for the movement of the extrusion block when the two shells are fitted together.

[0009] In the above-mentioned water-cooling plug for the water-cooling channel of a battery box, the end of the extrusion block forms an extrusion portion, and the extrusion space is formed between the extrusion portion and the end of the main block. When the extrusion block moves in the main block, the extrusion portion and the end of the main block approach or move away from each other, thereby changing the size of the extrusion space.

[0010] In the above-mentioned water-cooling plug for the water-cooling channel of a battery box, the upper end of the extrusion block extends outward along the thickness direction of the extrusion block to form a pushing block, and notches are provided on both sides of the main block. When the extrusion block is inserted into the main block, the pushing block passes through the notch and movably abuts against the end face of the channel.

[0011] In the above-mentioned water-cooling plug for the water-cooling channel of the battery box, guide grooves are provided at both ends of the main block along the length direction, and guide parts are provided at both ends of the extrusion block, and the guide parts are movably inserted in the guide grooves.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 4As shown, a water-cooling plug for a water-cooling channel of a battery box of the present invention is used to seal the end of the channel 4, comprising: a main body block 1, which is detachably connected to the channel 4; an extrusion block 2, which is movably arranged in the main body block 1, and an extrusion space is formed between the main body block 1 and the extrusion block 2, and a sealing ring 3 is provided in the extrusion space; when the main body block 1 is inserted into the channel 4, the channel 4 pushes the extrusion block 2 to move on the main body block 1 to reduce the width of the extrusion space and compress the sealing ring 3, so that the sealing ring 3 is pressed against the side wall of the channel 4.

[0023] The detachable connection between the main body block 1 and the flow channel 4 can facilitate the disassembly and assembly between the plug and the flow channel 4, and can also facilitate the replacement of the plug after the plug reaches its service life.

[0024] When the plug is pushed into the flow channel 4 , the sealing ring 3 is expanded by force and pressed against the side wall of the flow channel 4 , thereby achieving the purpose of filling the end of the flow channel 4 and ensuring the sealing of the flow channel 4 .

[0025] The main block 1 includes two symmetrically arranged shells 5. When the two shells 5 are fitted together, they form an accommodating space for the extrusion block 2 to move. Splitting the main block 1 into two shells 5 can facilitate the installation of the extrusion block 2 and the sealing ring 3. Preferably, after the two shells 5 are respectively sleeved on the outside of the extrusion block 2, the two shells 5 can be connected by bonding.

[0026] An extrusion portion 6 is formed at the end of the extrusion block 2, and an extrusion space is formed between the extrusion portion 6 and the end of the main block 1. When the extrusion block 2 moves in the main block 1, the extrusion portion 6 and the end of the main block 1 move closer to or farther away from each other, thereby changing the size of the extrusion space. Providing the extrusion portion 6 at the end of the extrusion block 2 can facilitate the change of the size of the extrusion space when the extrusion block 2 moves, thereby facilitating the extrusion expansion of the sealing ring 3.

[0027] like Figure 3 and Figure 4 As shown, the upper end of the extrusion block 2 extends outward along the thickness direction of the extrusion block 2 to form a push block 7, and notches 8 are provided on both sides of the main block 1. When the extrusion block 2 is inserted into the main block 1, the push block 7 passes through the notch 8 and movably abuts against the end face of the flow channel 4.

[0028] During installation, the plug is inserted into the flow channel 4. As the plug is inserted, the pushing block 7 provided on the extrusion block 2 moves in the direction opposite to the moving direction of the plug under the push of the end of the flow channel 4. When the pushing block 7 moves, the size of the extrusion space is reduced and the sealing ring 3 is compressed to ultimately achieve the purpose of ensuring the sealing of the flow channel 4.

[0029] As a preferred solution of the present invention, guide grooves 9 are provided at both ends of the main block 1 along the length direction, and guide parts 10 are provided at both ends of the extrusion block 2. The guide parts 10 are movably inserted in the guide grooves 9. The setting of the guide grooves 9 and the guide parts 10 can ensure the accuracy of the moving direction of the extrusion block 2 when it moves, thereby ensuring that the sealing ring 3 will not tilt in the flow channel 4.

[0030] As another preferred embodiment of the present invention, a plurality of clips 11 are provided on the outer wall of the main block 1, and a number of slots 12 equal to the number of the clips 11 are provided on the flow channel 4. The clips 11 are movably connected in the slots 12. The arrangement of the clips 11 and the slots 12 can facilitate the disassembly and assembly between the plug and the flow channel 4.

[0031] As another preferred embodiment of the present invention, the sealing ring 3 has a symmetrical structure. The symmetrically arranged sealing ring 3 can enhance the sealing performance of the sealing ring 3 after being squeezed and expanded.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, in the present invention, descriptions such as "first," "second," and "one" are for descriptive purposes only and should not be understood to indicate or imply their relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0034] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
