Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power batteries, and particularly provides a joint assembly, 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 is dissipated during operation. Usually, a set of dedicated water cooling pipelines are used in the battery pack to control the temperature of the battery. As the requirements for the power and driving 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. In the traditional cooling system, a vehicle-end water quick connector is arranged on the vehicle body, and a pack-end water quick connector is arranged on the battery pack. The on-off of the cooling system pipeline is realized through the connection and separation of the vehicle-end water quick connector and the pack-end water quick connector. During the conduction process between the vehicle-end and the pack-end water quick connectors, the moving valve core moves in the Z direction, and the pressing surfaces of the fixed valve core and the moving valve core are not fully matched, which will cause the moving valve core to shift to one side during the movement in the Z direction. During the separation process between the vehicle-end and the pack-end water quick connectors, the moving valve core may get stuck around and cannot be restored, unable to achieve sealing, and thus resulting in leakage. In addition, during the battery swapping process, the mating surface of the pack-end water quick connector is exposed, and gravel may fall on the mating surface. During the conduction process between the vehicle-end and the pack-end water quick connectors, the gravel enters the cooling system, causing blockage.
[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 joint assembly that can improve the assembly stability and reliability.
[0005] The utility model provides a joint assembly, including:
[0006] A first joint, including a first mounting plate, a first connecting pipe provided on the first mounting plate, and a first mating portion provided on the first mounting plate;
[0007] A second joint, including a second mounting plate, a second mating portion provided on the second mounting plate, and a second connecting pipe provided on the second mounting plate;
[0008] Wherein, the first mating portion is connected to the second mating portion. The first mating portion includes a first valve core, the second mating portion includes a second valve core. The first valve core includes a body and a support portion close to the second valve core. The second valve core includes a main body portion and a convex portion close to the first valve core. The support portion includes a receiving cavity. The first valve core abuts against the second valve core and the convex portion is received in the receiving cavity.
[0009] In the case of adopting the above technical solution, the first valve core of the present utility model abuts against the second valve core, and the convex portion is received in the receiving cavity of the supporting portion. During the movement of the second valve core relative to the second mating portion, the convex portion is received in the receiving cavity under the guidance of the receiving cavity, which can not only play a guiding role, but also have a certain limiting effect, preventing the second valve core from shifting to one side during the Z-direction movement, thus affecting the sealing and causing coolant leakage, and further affecting the stability of the assembly.
[0010] In the preferred technical solution of the above joint assembly, the convex portion includes a first guiding portion and a second guiding portion provided at the end of the first guiding portion, and the diameter of the first guiding portion gradually decreases from the main body portion to the second guiding portion.
[0011] In the case of adopting the above technical solution, the first guiding portion is a structure with a gradually decreasing diameter from the main body portion. Such a tapered structure can play a better guiding and positioning role.
[0012] In the preferred technical solution of the above joint assembly, the inner wall of the receiving cavity includes a guiding surface and a mating surface, the first guiding portion abuts against the guiding surface, and the second guiding portion abuts against the mating surface.
[0013] In the case of adopting the above technical solution, the guiding surface and the mating surface of the inner wall of the receiving cavity are structural shapes adapted to the first guiding portion and the second guiding portion of the convex portion, so that during the movement of the first valve core and the second valve core, a better matching effect is achieved, playing a better guiding role. At the same time, because the first guiding portion abuts against the guiding surface and the second guiding portion abuts against the mating surface, not only can abutment be achieved, but also positioning can be carried out, which can increase the stability and reliability during the assembly process.
[0014] In the preferred technical solution of the above joint assembly, the first guiding portion is inclined with respect to the horizontal direction and the second guiding portion is a plane.
[0015] In the case of adopting the above technical solution, the first guiding portion is inclined with respect to the horizontal direction, that is, the first guiding portion has a certain slope, so there is no need to worry about gravel falling on the mating surface and then entering the cooling system during the opening process of the second valve core, thus causing blockage.
[0016] In the preferred technical solution of the above joint assembly, the angle between the inclined surface of the first guiding portion and the horizontal direction is 10 degrees to 50 degrees.
[0017] In the case of adopting the above technical solution, the angle between the inclined surface of the first guiding portion and the horizontal direction is 10 degrees to 50 degrees. When the first guiding portion is engaged with the mating surface, it can ensure the transmission of the Z-direction abutting force during assembly. Due to the existence of the inclined angle, if there is an angular offset in the abutting, the first guiding portion will provide a force in the horizontal direction, thereby enabling the first guiding portion to be aligned and mated with the mating surface, and further improving the assembly stability. At the same time, the inclined angle is 10 degrees to 50 degrees, and there will be no stacking or staying of gravel on the first guiding surface, so that the gravel can enter the cooling system, ensuring the reliability of the assembly.
[0018] In the preferred technical solution of the above joint assembly, the angle between the guiding surface and the horizontal direction is 10 degrees to 50 degrees.
[0019] In the case of adopting the above technical solution, the angle between the guiding surface and the horizontal direction is 10 degrees to 50 degrees, making the inclined angle of the first guiding portion corresponding to the guiding surface. It can not only ensure the transmission of the Z-direction abutting force during assembly, but also correct the offset of the first guiding portion, thereby improving the assembly stability and reliability.
[0020] In the preferred technical solution of the above joint assembly, the ratio of the diameter of the second guiding portion to the diameter of the main body portion is 0.1 to 0.5.
[0021] In the case of adopting the above technical solution, the setting of this ratio can not only ensure that the first guiding portion is conical, and will not make the second guiding portion too small, thereby affecting the assembly stability of the first joint and the second joint, but also will not make the second guiding portion too large, resulting in gravel falling on the second guiding portion, thereby damaging the first joint and the second joint and affecting the reliability of the first joint and the second joint.
[0022] In the preferred technical solution of the above joint assembly, the first mating portion further includes a first elastic member and a sleeve connected to the first elastic member. The first elastic member is sleeved on the first valve core, and the sleeve can move relative to the first valve core. The second mating portion further includes a second elastic member sleeved on the second valve core.
[0023] In the case of adopting the above technical solution, elastic members are provided in the first mating portion and the second mating portion. The sleeve in the first joint is elastically compressed by the abutment of the second joint, thereby enabling the sleeve to move in the first joint. The second valve core in the second joint is abutted by the first valve core, thereby enabling the second valve core to move in the second joint. The settings of the first elastic member and the second elastic member can realize the on-off of the communication channel between the first joint and the second joint during assembly.
[0024] In a second aspect, the present invention provides a cooling system, including the joint assembly described in the first aspect.
[0025] In a third aspect, the present utility model provides an electrical device, including the cooling system described in the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The preferred embodiments of the present utility model will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0037] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and defined, 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 circumstances.
[0038] As Figures 1 to 5 shown, in the first aspect, the joint assembly of the present utility model includes a first joint 1 and a second joint 2. The first joint 1 includes a first mounting plate 10 and a first connecting pipe and a first fitting portion 12 provided on opposite sides of the first mounting plate 10. The second joint 2 includes a second mounting plate 20 and a second fitting portion 21 and a second connecting pipe 22 provided on opposite sides of the second mounting plate 20. The first fitting portion 12 is connected to the second fitting portion 21. The first fitting portion 12 includes a first valve core 121, and the second fitting portion 21 includes a second valve core 211. The first valve core 121 includes a body 1211 and a support portion 1212 provided on the side of the body 1211 close to the second valve core 211. The second valve core 211 includes a main body portion 2110 and a convex portion 2112 provided on the side of the main body portion 2110 close to the first valve core 2112. The support portion 1212 includes a receiving cavity 1213. The first valve core 121 abuts against the second valve core 211 and the convex portion 2112 is received in the receiving cavity 1213.
[0039] The first valve core 121 of the present utility model abuts against the second valve core 211, and the convex portion 2112 is received in the receiving cavity 1213 of the support portion 1212. During the movement of the second valve core 211 relative to the second fitting portion 21, the convex portion 2112 is received in the receiving cavity 1213 under the guidance of the receiving cavity 1213. It can not only play a guiding role but also have a certain limiting effect, preventing the second valve core 211 from shifting to one side during the movement in the Z direction, thereby affecting the seal and causing coolant leakage, and thus affecting the stability of the assembly.
[0040] As Figures 1 to 2 、 Figures 3 to 4As shown, the first mating part 12 further includes a first elastic member 123 and a sleeve 122 connected to the first elastic member 123. The first elastic member 123 is sleeved on the first valve core 121, and the sleeve 122 can move relative to the first valve core 121. The second mating part 21 further includes a second elastic member 213 sleeved on the second valve core 211. When the first joint 1 and the second joint 2 are assembled, since the first elastic member 123 is provided in the first mating part 12 and the second elastic member 213 is provided in the second mating part 21, the sleeve 122 in the first joint 1 is elastically compressed by being abutted by the second joint 2, thereby causing the sleeve 122 to move within the first joint 1. The second valve core 211 in the second joint 2 is abutted by the first valve core 121, thereby causing the second valve core 211 to move within the second joint 2. The provision of the first elastic member 123 and the second elastic member 213 can achieve the on-off of the communication channel between the first joint 1 and the second joint 2 during assembly.
[0041] Referring to Figure 2 、 Figures 4 to 5 , the convex portion 2112 includes a first guiding portion 2113 and a second guiding portion 2114 provided at the end of the first guiding portion 2113. The diameter of the first guiding portion 2113 gradually decreases from the main body portion 2110 to the second guiding portion 2114. The first guiding portion 2113 is a structure with a gradually decreasing diameter from the main body portion 2110. Such a tapered structure can play a good guiding and positioning role. In this embodiment, the first guiding portion 2113 is tapered and the second guiding surface 2114 is a plane, that is, the first guiding portion 2113 has a certain slope, so there is no need to worry about gravel, stones, etc. falling on the inclined surface and then entering the cooling system during the opening process of the second valve core 211, thus causing blockage.
[0042] Referring to Figures 3 to 5 , the inner wall of the receiving cavity 1213 includes a guiding surface 1214 and a mating surface 1215. The first guiding portion 2113 abuts against the guiding surface 1214, and the second guiding portion 2114 abuts against the mating surface 1215. The guiding surface 1214 and the mating surface 1215 of the inner wall of the receiving cavity 1213 are structural shapes adapted to the first guiding portion 2114 and the second guiding portion 2115 of the convex portion 2112, so that the first valve core 121 and the second valve core 211 have a better matching effect during movement, playing a good guiding role. At the same time, because the first guiding portion 2113 cooperates with the guiding surface 1214 and the second guiding portion 2114 cooperates with the mating surface 1215, not only can abutment be achieved, but also positioning can be carried out, which can increase the stability and reliability during the assembly process. The second guiding portion 2114 is a plane perpendicular to the Z direction, and has good contact stability after the first guiding portion 2113 cooperates with the guiding surface 1214.
[0043] Referring to Figure 3 and Figure 5, the inclination angle α of the guiding surface 1214 is from 10 degrees to 50 degrees. This inclination angle α is the angle between the guiding surface 1214 and the horizontal direction. In this embodiment, the inclination angle α can be 12 degrees, 14 degrees, 15 degrees, 16 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 25 degrees, 26 degrees, 28 degrees, 30 degrees, 32 degrees, 34 degrees, 35 degrees, 36 degrees, 38 degrees, 40 degrees, 42 degrees, 44 degrees, 45 degrees, 46 degrees, 48 degrees, 50 degrees, such that the inclination angle of the first guiding portion 2113 corresponds to that of the guiding surface 1214, which can not only ensure the transmission of the Z - direction abutting force during assembly, but also correct the offset of the first guiding portion 2113, thereby improving the stability and reliability of the assembly. The mating surface 1215 is a plane in contact with the second guiding portion 2114 and is perpendicular to the Z - direction.
[0044] Refer to Figure 2 , Figures 4 to 5 , the inclination angle β of the first guiding portion 2113 is from 10 degrees to 50 degrees. In this embodiment, the inclination angle β can be 12 degrees, 14 degrees, 15 degrees, 16 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 25 degrees, 26 degrees, 28 degrees, 30 degrees, 32 degrees, 34 degrees, 35 degrees, 36 degrees, 38 degrees, 40 degrees, 42 degrees, 44 degrees, 45 degrees, 46 degrees, 48 degrees, 50 degrees. This inclination angle β is the angle between the inclined surface of the first guiding portion 2113 and the horizontal direction. The inclination angle β of the first guiding portion 2113 being from 10 degrees to 50 degrees, when the first guiding portion 2113 mates with the mating surface 1215, it can not only ensure the transmission of the Z - direction abutting force during assembly. Due to the existence of the inclination angle, such as an angular offset during abutment, the first guiding portion 2113 will provide a force in the horizontal direction, thereby enabling the first guiding portion 2113 to be in alignment and mating with the mating surface 1215, thus improving the stability of the assembly; at the same time, since the inclination angle β is from 10 degrees to 50 degrees, no debris such as gravel and stones will stack or stay on the first guiding portion 2113, preventing such debris from entering the cooling system and ensuring the reliability of the assembly.
[0045] Refer to Figures 4 to 5 , the ratio of the diameter of the second guiding portion 2114 to the diameter of the main body portion 2110 is from 0.1 to 0.5. This ratio setting can not only ensure that the first guiding portion 2113 is conical, preventing the second guiding portion 2114 from being too small and thus affecting the assembly stability of the first joint 1 and the second joint 2, but also prevent the second guiding portion 2114 from being too large, which may cause debris such as gravel and stones to fall on the second guiding portion 2114, thereby damaging the first joint 1 and the second joint 2 and affecting the reliability of the first joint 1 and the second joint 2.
[0046] In a second aspect, the cooling system of the present utility model includes the joint assembly of the first aspect. The cooling system of this technical solution includes the joint assembly of any technical solution of the present utility model, and thus has all the technical effects of the joint assembly of any technical solution of the present utility model.
[0047] 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 the cooling system of any technical solution of the present utility model, and thus has all the technical effects of the cooling system of any technical solution of the present utility model.
[0048] It should be noted that the above preferred embodiments are only used to illustrate the principle of the present utility model and are not intended to limit the protection scope of the present utility model. Without departing from the principle of the present utility model, those skilled in the art can adjust the above settings so that the present utility model can be applied to more specific application scenarios.
[0049] Of course, the above replaceable embodiments can be used in cross combination with each other, and also with the preferred embodiments, so as to combine new embodiments to be applicable to more specific application scenarios.
[0050] So far, the technical solution of the present utility model has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments.
