Description

Technical Field

[0001] The utility model relates to the technical field of power batteries, and particularly provides a connector, a cooling system and an electrical equipment. Background Art

[0002] With the development of society, in order to reduce the pollution of automobile exhaust to the atmosphere, new energy vehicles such as lithium batteries have been vigorously promoted at present. As the on-vehicle battery serving as the power source of new energy vehicles, a large amount of heat will be dissipated during operation. Usually, a set of special water-cooling pipelines will be used in the battery pack to control the temperature of the battery. As the requirements for the power and cruising range of new energy vehicles from the outside world are getting higher and higher, the volume of the battery module is also getting larger and larger, making the layout conditions of the water-cooling pipelines higher. The traditional quick-change connector at the end of the battery pack needs to be connected to the pipe. During the assembly process of the pipe and the quick-change connector at the end of the battery pack, the pipe will shake in the horizontal direction. Because the volume of the sealing ring is relatively large before compression, deformation, falling off or improper installation will occur during the assembly process, thereby affecting the stability and reliability of the assembly. In addition, when the sealing ring on the pipe is assembled to the quick-change connector at the end of the battery pack, the sealing ring is not compressed and is easy to contact with the quick-change connector at the end of the battery pack, thereby posing a risk of the sealing ring being extruded.

[0003] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Utility Model

[0004] The utility model aims to solve the above technical problems and provides a new connector that can improve the assembly stability and reliability.

[0005] The utility model provides a connector, comprising:

[0006] A main body part, including a base body, an insertion pipe arranged on the first side of the base body, and a first fitting part arranged on the second side of the base body;

[0007] A pipe, including a second fitting part and a connecting pipe;

[0008] Wherein, the second fitting part is connected and fitted with the first fitting part. The base body has a first surface arranged on the first side and a second surface arranged on the second side, and the first surface and the second surface are arranged opposite to each other. The main body part further includes a guiding part extending from the insertion pipe towards the second side. The first fitting part includes a boss arranged on the second surface and a clamping part connected to the boss, and the guiding part extends beyond the boss.

[0009] In the case of adopting the above technical solution, the main body part of the joint of the present utility model includes a guiding part extending from the insertion pipe towards the second side direction, and the guiding part extends beyond the boss. When the pipe is assembled with the main body part, the second fitting part will be guided by the guiding part before contacting the boss, and the second fitting part will not shake during assembly, thereby improving the stability and reliability of assembly.

[0010] In a preferred technical solution of the above joint, the main body part further includes a receiving cavity provided outside the guiding part, and the second fitting part is provided in the receiving cavity.

[0011] In the case of adopting the above technical solution, the guiding part is provided in the receiving cavity, which can not only realize the assembly of the pipe and the main body part, but also the setting of the receiving cavity outside the guiding part can save the occupied space of the whole joint in the installation direction, which is beneficial to reducing the volume.

[0012] In a preferred technical solution of the above joint, a chamfer or a fillet is provided at the connection between the inner wall of the receiving cavity and the boss.

[0013] In the case of adopting the above technical solution, a chamfer or a fillet is provided at the connection between the inner wall of the receiving cavity and the boss, which can play a certain guiding role when the pipe is assembled to the main body part. At the same time, because the sealing ring in the joint is not compressed during assembly, the situation that the sealing ring is blocked and damaged during assembly will not occur.

[0014] In a preferred technical solution of the above joint, the second fitting part includes a blocking part provided in the receiving cavity and located outside the guiding part.

[0015] In the case of adopting the above technical solution, when the second fitting part is assembled with the first fitting part, it will be guided by the guiding part into the receiving cavity. The blocking part is located outside the guiding part to realize the assembly, which can improve the convenience of assembly. In addition, the blocking part is located outside the guiding part, which can limit the horizontal shaking of the blocking part and the guiding part, play a positioning role, and further improve the stability and reliability of assembly.

[0016] In a preferred technical solution of the above joint, a sealing ring is provided between the blocking part and the inner wall of the receiving cavity.

[0017] In the case of adopting the above technical solution, a sealing ring is provided between the blocking part and the inner wall of the receiving cavity, which can realize the sealing between the main body part and the pipe, and at the same time prevent the horizontal shaking of the main body part and the pipe during assembly and use.

[0018] In a preferred technical solution of the above joint, the blocking part includes a crimping part arranged along the reverse extension direction of the guiding part and a separating part arranged on the crimping part and perpendicular to the crimping part.

[0019] In the case of adopting the above technical solution, the extending directions of the crimping portion and the guiding portion are opposite, which facilitates the assembly of the two and enables a firm fit. The separating portion is perpendicular to the crimping portion. The separating portion can divide the crimping portion into two spaces, which can not only achieve the separation of the space, but also increase the overall strength of the blocking portion.

[0020] In a preferred technical solution of the above joint, the crimping portion, the separating portion and the inner wall of the receiving cavity form two adjacent sub-cavities.

[0021] In the case of adopting the above technical solution, the separating portion divides the space between the crimping portion and the inner wall of the receiving cavity into two sub-cavities, which can increase the utilization rate of the space. And because of the radial strengthening of the separating portion, the installation stability can be increased.

[0022] In a preferred technical solution of the above joint, the joint further includes sealing rings arranged in the two sub-cavities.

[0023] In the case of adopting the above technical solution, by arranging sealing rings in the two sub-cavities, the situation of leakage due to the failure of a single sealing ring can be prevented. The double-channel sealing makes the sealing more secure and improves the reliability of the sealing.

[0024] In a second aspect, the present invention provides a cooling system, including the joint described in the first aspect.

[0025] In a third aspect, the present invention provides an electrical equipment, including the cooling system described in the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "connection", "setting", "installation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] As Figures 1 to 3 shown, in the first aspect, the joint of the present utility model includes a main body part 1 and a pipe 2. The main body part 1 is generally plate-shaped. The main body part 1 includes a base body 10, an insertion pipe 11 provided on the first side of the base body 10, and a first mating part 12 provided on the second side of the base body 10. The pipe 2 includes a second mating part 21 and a connecting pipe 22. The second mating part 21 is connected and mated with the first mating part 12. The insertion pipe 11 is inserted and mated with the second joint. The base body 10 has a first surface 13 provided on the first side and a second surface 14 provided on the second side. The first surface 13 and the second surface 14 are arranged opposite to each other. The main body part 1 further includes a guiding part 15 extending from the insertion pipe 11 towards the second side. The first mating part 12 includes a boss 121 provided on the second surface 14 and a clamping part 122 connected to the boss 121. The guiding part 15 extends beyond the boss 121. The extending direction of the guiding part 15 is the Z direction. The connecting pipe 22 is lower than the insertion pipe 11 in the Z direction. The bottom surface of the guiding part 15 is lower than the bottom surface of the boss 121.

[0037] The main body part 1 of the joint of the present utility model includes a guiding part 15 extending from the insertion pipe 11 towards the second side direction. The guiding part 15 extends beyond the boss 121. When the pipe 2 is assembled with the main body part 1, the second fitting part 21 will be guided by the guiding part 15 before contacting the boss 121, and the second fitting part 21 will not shake during assembly, thereby improving the stability and reliability of the assembly.

[0038] As Figure 1 and Figure 3 shown, the main body part 1 further includes a stepped part 19 protruding outward from the second surface 14. The stepped part 19 is provided with a through hole and is located at four corners for mounting with the vehicle body or the battery pack. The thickness of the stepped part 19 is greater than the thickness of the base body 10, which can play a strengthening role. The main body part 1 further includes a receiving cavity 23 provided outside the guiding part 15. The second fitting part 21 is arranged in the receiving cavity 23, and the guiding part 15 is arranged in the receiving cavity 23, which can not only realize the assembly of the pipe 2 and the main body part 1, but also save the occupied space of the whole joint in the installation direction by arranging the receiving cavity 23 outside the guiding part 15, which is beneficial to reducing the volume. A chamfer or a fillet is provided at the connection between the inner wall of the receiving cavity 23 and the boss 121, which can play a certain guiding role when the pipe is assembled to the main body part 1. At the same time, since the sealing ring 24 in the joint is not compressed during assembly, the situation that the sealing ring 24 is blocked and damaged during assembly will not occur. Both the insertion pipe 11 and the pipe 2 are hollow and internally connected, thereby realizing the circulation of the cooling liquid.

[0039] Referring to Figures 1 to 2 , the second fitting part 21 includes a blocking part 211 arranged in the receiving cavity 23 and located outside the guiding part 15. When the second fitting part 21 is assembled with the first fitting part 12, it will be guided by the guiding part 15 into the receiving cavity 23. The blocking part 211 is located outside the guiding part 15 to realize the assembly, which can improve the convenience of the assembly. In addition, since the blocking part 211 is located outside the guiding part 15, it can limit the horizontal shaking of the blocking part 211 and the guiding part 15, playing a positioning role, thereby improving the stability and reliability of the assembly. A sealing ring 24 is provided between the blocking part 211 and the inner wall of the receiving cavity 23, which can realize the sealing between the main body part 1 and the pipe 2 and prevent the horizontal shaking of the main body part 1 and the pipe 2 during assembly and use.

[0040] Referring to Figure 3, the blocking portion 211 includes a crimping portion 2111 disposed along the reverse extension direction of the guiding portion 15 and a partitioning portion 2112 provided on the crimping portion 2111 and perpendicular to the crimping portion 2111. The crimping portion 2111 extends in the opposite direction to the extension direction of the guiding portion 15, which facilitates the assembly of the two and enables a firm fit. The partitioning portion 2112 is perpendicular to the crimping portion 2111. The partitioning portion 2112 can divide the crimping portion 2111 into two spaces, which can not only achieve the partitioning of the space but also increase the overall strength of the blocking portion 211.

[0041] As Figure 1 shown, the crimping portion 2111, the partitioning portion 2112 and the inner wall of the receiving cavity 23 form two adjacent sub-cavities. The partitioning portion 2112 divides the space between the crimping portion 2111 and the inner wall of the receiving cavity 23 into two sub-cavities, which can increase the utilization rate of the space and, due to the radial strengthening of the partitioning portion 2112, can increase the installation stability. The joint further includes sealing rings 24 provided in the two sub-cavities. Setting the sealing rings 24 in the two sub-cavities can prevent the situation of leakage due to the failure of a single sealing ring 24. The double-channel seal makes the seal more secure and improves the reliability of the seal.

[0042] In a second aspect, the cooling system of the present utility model includes the joint of the first aspect. The cooling system of this technical solution includes a joint according to any technical solution of the present utility model, and thus it has all the technical effects of the joint of any technical solution of the present utility model.

[0043] In a third aspect, the electrical equipment of the present utility model includes the cooling system of the second aspect. The electrical equipment of this technical solution includes a cooling system according to any technical solution of the present utility model, and thus it has all the technical effects of the cooling system of any technical solution of the present utility model.
