Description

Technical Field

[0001] The utility model relates to the technical field of power batteries, and specifically provides a joint assembly, a cooling system and 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. As the power source of new energy vehicles, the on-board battery will dissipate a lot of heat when working. Usually, a set of special water cooling pipes are used in the battery pack to control the temperature of the battery. As the outside world's requirements for the power and mileage of new energy vehicles are getting higher and higher, the size of the battery module is getting larger and larger, which makes the layout conditions of the water cooling pipe more demanding. The traditional water quick-change assembly needs to connect the quick-plug connector with the water quick-change connector first, and then connect the water cooling pipe with the quick-plug connector. Not only does it take a long time to assemble and test, but it is also prone to the risk of liquid leakage. In addition, both sides of the water quick-change connector need to be connected with quick-plug connectors, and the number of parts is large and the cost is high.

[0003] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the above technical problems and provide a new type of joint assembly which can reduce assembly time, lower the risk of liquid leakage, reduce the number of parts and save costs.

[0005] The utility model provides a joint assembly, comprising:

[0006] A connector, the connector comprising a base, a plug-in tube arranged on a first side of the base, and a pipe arranged on a second side of the base;

[0007] A connecting pipeline, the connecting pipeline includes a first connecting section, a second connecting section and a corrugated section connecting the first connecting section and the second connecting section, and the first connecting section is cooperatively connected with the piping.

[0008] In the case of adopting the above technical solution, the connector of the utility model includes a plug-in tube and a pipe, and the first connecting section of the connecting pipeline is directly connected to the pipe, eliminating the intermediate connecting adapter, which not only reduces the number of parts and saves costs, but also directly connects to the pipe through the first connecting section, and does not need to connect the adapter first, and then connect the connecting pipe or pipe, which saves assembly time. At the same time, because the number of assemblies is reduced, the risk of liquid leakage can be reduced. In addition, the plug-in tube and the pipe are respectively arranged on the first side and the second side of the base, which can not only save the horizontal space occupied by the connector assembly, but also reduce the flow resistance of the liquid passing through the connector assembly, and improve the heat dissipation effect and heat exchange efficiency.

[0009] In a preferred technical solution of the above-mentioned joint assembly, the first connecting section is sleeved on the pipe and the first connecting section and the pipe are interference fit.

[0010] When the above technical solution is adopted, the first connecting section is connected to the pipe by cold extrusion and has an interference fit with the pipe, which not only can achieve reliable connection and fit between the connecting pipe and the joint, but also can eliminate the adapter joint between the connecting pipe and the joint, reducing the number of parts and saving assembly time.

[0014] When the above technical solution is adopted, when the first connecting section is cold-extruded and sleeved on the connecting pipe and abuts against the retaining ring, the retaining ring will limit the first connecting section to prevent the connecting pipeline from being further plugged in; the guide portion provided at the first end of the connecting pipe guides the plugged connecting pipeline; the connecting pipe includes at least one annular protrusion, which is provided in the shape of an inverted tooth, which not only guides the plugging of the connecting pipeline, but also, because of the setting of the inverted tooth, after the first connecting section is sleeved on the piping, it will not be easily pulled out, thereby reducing the risk of liquid leakage and increasing the reliability of assembly.

[0015] In a preferred technical solution of the above-mentioned joint assembly, an annular groove is provided between the guide portion and the annular protrusion, and a sealing ring is provided in the annular groove.

[0016] When the above technical solution is adopted, by providing an annular groove and a sealing ring near the end, the sealing performance of the sleeve connection can be effectively improved, liquid leakage can be prevented, and the reliability of assembly can be increased.

[0017] In a preferred technical solution of the above-mentioned joint assembly, the length of the corrugated section is not less than the length of the first connecting section and / or the second connecting section.

[0018] When the above technical solution is adopted, the space occupied by the adapter joint is saved by directly socketing the connecting pipeline and the piping. Within the same space, the length of the corrugated section can be increased, thereby reducing the flow resistance of the liquid.

The quick-plug connector is connected to the heat exchange component to achieve the connection between the connecting pipeline and the heat exchange component, thereby improving assembly efficiency.

[0021] In a preferred technical solution of the above-mentioned joint assembly, the number of the plug-in tubes is two and the number of the pipes is two, the two pipes extend in a direction away from the base, and the extension direction of the plug-in tube is perpendicular to the extension direction of the pipes.

[0022] When the above technical solution is adopted, the plug-in tube is one-in and one-out, the piping is also one-in and one-out, the plug-in tube at the liquid inlet end corresponds to and is connected with the piping, and the plug-in tube at the liquid outlet end corresponds to and is connected with the piping.

The extension direction of the plug-in tube is perpendicular to the extension direction of the piping, which can make good use of the height direction space of the battery pack and save the horizontal direction space of the battery pack, thereby improving space utilization and thereby improving the overall energy of the battery pack.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figures 1 to 5As shown, in the first aspect, the connector assembly of the utility model includes a connector 1 and a connecting pipeline 2, the connector 1 includes a base 10, a plug-in tube 11 arranged on a first side of the base 10 and a pipe 12 arranged on a second side of the base 10, the connecting pipeline 2 includes a first connecting section 21, a second connecting section 23 and a corrugated section 22 connecting the first connecting section 21 and the second connecting section 23, and the first connecting section 21 is cooperatively connected with the pipe 12.

[0039] The connector 1 of the utility model includes a plug-in tube 11 and a pipe 12. The first connecting section 21 of the connecting pipe 2 is directly connected to the pipe 12, eliminating the intermediate connecting adapter, which not only reduces the number of parts and saves costs, but also directly connects to the pipe 12 through the first connecting section 21, and does not need to connect the adapter first, and then connect the connecting pipe 2 or the pipe 12, which saves assembly time. At the same time, because the number of assemblies is reduced, the risk of liquid leakage can be reduced. In addition, the plug-in tube 11 and the pipe 12 are respectively arranged on the first side and the second side of the base 10, which can not only save the horizontal space occupied by the connector assembly, but also reduce the flow resistance of the liquid passing through the connector assembly, and improve the heat dissipation effect and heat exchange efficiency.

[0040] like Figure 4 and Figure 5 As shown, there are two plug-in tubes 11 and two pipes 12. The two pipes 12 extend in a direction away from the base 10. The extension direction of the plug-in tube 11 is perpendicular to the extension direction of the pipe 12. The plug-in tube 11 is one-in and one-out, and the pipe 12 is also one-in and one-out. The plug-in tube 11 at the liquid inlet end is correspondingly arranged and connected with the pipe 12, and the plug-in tube 11 at the liquid outlet end is correspondingly arranged and connected with the pipe 12. The plug-in tube 11 is provided with a first cavity (unnumbered) connected with the vehicle end connector, and the pipe 12 is provided with a second cavity (unnumbered) connected with the first cavity. The two pipes 12 at the liquid inlet end and the liquid outlet end extend in a direction away from the base 10, that is, the two pipes 12 at the liquid inlet end and the liquid outlet end are arranged in directions away from each other, which not only facilitates the collection and dispersion of the liquid, but also can maintain the stability and balance of the joint 1 when the liquid flows. In addition, such a configuration is also convenient for the installation and assembly of the joint assembly. The extension direction of the plug-in tube 11 is perpendicular to the extension direction of the piping 12, which can make good use of the height space of the battery pack, save the horizontal space of the battery pack, improve space utilization, arrange more battery cells, and thus improve the energy density of the battery pack.

[0041] Reference Figure 1 to Figure 2 The first connecting section 21 is sleeved on the pipe 12 by cold extrusion and has an interference fit with the pipe 12, which can not only realize the reliable connection and fit between the connecting pipe 2 and the joint 1, but also eliminate the adapter joint between the connecting pipe 2 and the joint 1, thereby reducing the number of parts and saving assembly time.

[0042] Reference Figure 1 to Figure 2 and Figures 4 to 5 The piping 12 includes a main pipe 121 and a connecting pipe 122 connected to the main pipe 121. The main pipe 121 is connected to the substrate 10. The first connecting section 21 is sleeved on the connecting pipe 122, that is, the first connecting section 21 is sleeved on the connecting pipe 122 by cold extrusion to achieve the installation and sealing of the connecting pipeline 2 and the piping 12.

[0043] Reference Figures 4 to 5 The connecting pipe 122 includes at least one annular protrusion and a guide portion 1222 provided at the first end of the connecting pipe 122. In the embodiment of the utility model, two annular protrusions are provided, namely a first annular protrusion 1223 and a second annular protrusion 1224, and the first annular protrusion 1223 and the second annular protrusion 1224 are arranged at intervals. A retaining ring 1221 is provided at the second end of the connecting pipe 122, and the two annular protrusions are arranged between the retaining ring 1221 and the guide portion 1223. When the first connecting section 21 and the connecting pipe 122 are cold-extruded and sleeved and abut against the retaining ring 1221, the retaining ring 1221 will limit the first connecting section 21 to prevent the connecting pipeline 2 from being further plugged in. The guide portion 1222 provided at the end of the connecting pipe 122 guides the plugged connecting pipeline 2. The connecting pipe 122 includes at least one annular protrusion, which is arranged in the shape of an inverted tooth, which not only guides the insertion of the connecting pipe 2, but also, because of the setting of the inverted tooth, after the first connecting section 21 is sleeved on the pipe 12, it will not be easily pulled out, thereby reducing the risk of liquid leakage and increasing the reliability of assembly.

[0044] An annular groove 1225 is provided between the guide portion 1222 and the annular protrusion, and a sealing ring 1226 is provided in the annular groove 1225. By arranging the annular groove 1225 and the sealing ring 1226 near the end, the sealing of the socket can be effectively improved to prevent liquid leakage, thereby increasing the reliability of assembly.

[0045] like Figure 3As shown, the length of the corrugated section 22 is not less than the length of the first connecting section 21 and / or the second connecting section 23, that is, the length of the corrugated section 22 is greater than or equal to the length of the first connecting section 21 and / or the second connecting section 23. By directly connecting the connecting pipeline 2 and the pipe 12, the space occupied by the adapter joint is saved. In the same space, the length of the corrugated section 22 can be increased, thereby reducing the flow resistance of the liquid and flexibly adjusting the bending angle of the corrugated section 22 and the first connecting section 21 and / or the second connecting section 23, thereby improving the flexibility of assembly of the connecting pipeline 2. The corrugated section 22 includes a plurality of corrugated pipe crests 221 and a plurality of corrugated pipe troughs 222. The plurality of corrugated pipe crests 221 are stacked together, and the corrugated pipe troughs 222 are arranged between two adjacent corrugated pipe crests 221. The corrugated pipe crests 221 can move in the circumferential direction of the connecting pipeline 2, thereby realizing the bending of the corrugated section 22, which is not only convenient to operate but also can reduce costs.

[0046] like Figure 2 As shown, the joint assembly also includes a quick-connect joint 3 that is connected to the second connecting section 23. The quick-connect joint 3 is connected to the heat exchange assembly. The quick-connect joint 3 can be quickly plugged into and matched with the second connecting section 23 to save assembly time. The quick-connect joint 3 is connected to the heat exchange assembly to achieve the connection between the connecting pipeline 2 and the heat exchange assembly, thereby improving assembly efficiency.

The cooling system of this technical solution includes the joint assembly of any technical solution of the utility model, and thus has all the technical effects of the joint assembly of any technical solution of the utility model.

[0048] In the third aspect, the electrical equipment of the present invention includes the cooling system of the second aspect. The electrical equipment of this technical solution includes the cooling system of any technical solution of the present invention, and thus has all the technical effects of the cooling system of any technical solution of the present invention.
