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 popularization and promotion of new energy vehicles, the charging and discharging performance and endurance of new energy vehicles are increasingly attracting people's attention and attention. Quick-change connectors are widely used in the cooling lines of new energy vehicles. Different vehicle platforms and models have different battery replacement structures, which often requires battery replacement parts with floating mechanisms to adapt to different vehicle platforms and models. The current floating mechanism uses metal parts and springs to achieve floating and timely return to the X and Y directions. During use, quick-change connectors may experience metal or spring corrosion and wear, affecting the normal use of the quick-change connector and, in turn, the service life of the battery pack. In addition, the metal parts and springs have many parts and a complex structure, which is not conducive to the trend of miniaturization and lightweighting of battery packs, and also has high costs.

[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 with a simple structure, reduced weight and extended service life.

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

[0006] The main body comprises a base and a mounting hole passing through the base;

[0007] A floating member is arranged in the mounting hole, and the floating member is provided with a through hole;

[0008] A mounting seat, passing through the through hole;

[0009] a pipe, disposed on the mounting seat;

[0010] The main body is provided with a first convex portion facing the floating member, the mounting seat is provided with a second convex portion facing the floating member, the floating member is provided with a first groove and a second groove, the first convex portion is provided in the first groove, and the second convex portion is provided in the second groove.

[0011] When the above technical solution is adopted, the utility model has a floating member disposed in the mounting hole and a mounting seat disposed in the through hole. When the joint assembly is installed with another joint assembly, only the floating member, a single component, is required to achieve adjustment in the X and Y directions. This not only simplifies the structure, reduces the number of components, and reduces costs, but also improves the reliability of the joint assembly. The main body is provided with a first protrusion, the mounting seat is provided with a second protrusion, and the floating member is provided with a first groove and a second groove. The first protrusion is disposed in the first groove, and the second protrusion is disposed in the second groove. This can prevent relative rotation between the mounting seat and the floating member, and between the floating member and the main body, thereby increasing the reliability of the connection and reducing the relative movement between the mounting seat and the main body caused by battery replacement and vehicle movement, thereby reducing damage to components and extending the service life of the joint assembly.

[0012] In a preferred technical solution of the above-mentioned joint assembly, the floating member has an inner wall and an outer wall, the first groove is provided on the outer wall, and the second groove is provided on the inner wall.

[0013] When adopting the above technical solution, grooves are provided on the inner and outer walls of the floating part, that is, an embedded structure is provided between the floating part and the main body, and an embedded structure is also provided between the floating part and the mounting seat, so that embedded structures are provided on the inner and outer sides of the floating part in the radial direction, which not only increases the elasticity and scalability of the floating part, but also prevents the relative rotation between the floating part and the main body and the relative rotation between the mounting seat and the floating part during the mating process of the joint assembly, which is not conducive to the use of the joint assembly.

[0014] In a preferred technical solution of the above-mentioned joint assembly, the floating member is constructed as two symmetrically arranged and connected elastic rings, and the first groove and the second groove are spaced apart along the radial direction of the rings.

[0015] When employing this technical solution, the ring is elastic, capable of radial movement and elastic deformation. When the mounting seat floats, the mounting seat compresses the ring in a certain direction, thereby achieving floating installation. Once installed, the ring rebounds to its uncompressed state. The first and second grooves, respectively provided on the inner and outer walls of the floating member, allow the floating member to fit snugly with the main body and mounting seat, without affecting the floating motion of the joint assembly during installation. This prevents relative rotation between the floating member and the main body, and between the mounting seat and the floating member.

[0016] In a preferred technical solution of the above-mentioned joint assembly, the first grooves are evenly spaced along the outer wall in the circumferential direction of the ring, and the second grooves are evenly spaced along the inner wall in the circumferential direction of the ring.

[0017] When the above technical solution is adopted, the first grooves are evenly spaced along the outer wall in the circumferential direction of the ring, and the second grooves are evenly spaced along the inner wall in the circumferential direction of the ring. This not only increases the uniformity and reliability of the connection, but also when the ring is subjected to pressure or tension, the connection between the ring and the main body and the mounting seat is evenly stressed, and will not cause damage to the floating parts due to uneven force.

[0018] In a preferred technical solution of the above-mentioned joint assembly, a connecting line between the first groove and the axis of the circular ring is not collinear with a connecting line between the second groove and the axis of the circular ring.

[0019] When the above technical solution is adopted, the connection lines between the first groove and the second groove and the axis are not collinear. When the ring is under pressure, tension or twisting, because they are not collinear, there is a certain thickness between the inner wall and the outer wall of the ring. The deformation of the first groove will not cause too much impact on the second groove. Similarly, the deformation of the second groove will not cause too much impact on the first groove, thereby increasing the stability and reliability of the connection and extending the service life of the joint assembly.

[0020] In a preferred technical solution of the above-mentioned joint assembly, the circular ring is provided with a plurality of through cavities, and the through cavities are spaced apart from the first groove in the radial direction and / or the through cavities are spaced apart from the second groove in the radial direction.

[0021] When adopting the above technical solution, the setting of multiple through cavities can not only reduce the overall material consumption of the floating part and reduce costs, but also improve the elasticity of the floating part without reducing the strength of the floating part, and can also change the stress distribution.

[0022] In a preferred technical solution of the above-mentioned joint assembly, a first incision is provided at the connection between the two circular rings, and the first incision is connected to the two through holes of the floating member.

[0023] When the above technical solution is adopted, a first incision is provided between the two rings, which can improve the elasticity of the floating part and change the stress of the floating part, while also facilitating the installation of the floating part and the mounting seat, thereby improving the convenience of installation.

[0024] In a preferred technical solution of the above-mentioned joint assembly, the circular ring is provided with a second incision, and the second incision is away from the first incision in the direction of the axis connecting the two circular rings.

[0025] When adopting the above technical solution, the second incision is set at the edge of the ring, which increases the elasticity of the floating part and enlarges the installation opening of the floating part, making it easier to install the mounting seat into the through hole, saving assembly time and improving assembly efficiency.

[0026] In a second aspect, the present invention provides a cooling system, comprising the joint assembly described in the first aspect.

[0027] In a third aspect, the present invention provides an electrical device, comprising the cooling system described in the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "connect," "dispose," and "install" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0042] like Figures 1 to 4 As shown, in the first aspect, the joint assembly of the present invention includes a main body 1, a floating part 2, a mounting seat 3 and a pipe 4. The main body 1 includes a base 10 and a mounting hole 11 passing through the base 10. The floating part 2 is arranged in the mounting hole 11. The floating part 2 is provided with a through hole 21. The mounting seat 3 is passed through the through hole 21. The pipe 4 is installed on the mounting seat 3. The main body 1 is provided with a first protrusion 12 facing the floating part 2. The mounting seat 3 is provided with a second protrusion 31 facing the floating part 2. The floating part 2 is provided with a first groove 22 and a second groove 23. The first protrusion 12 is provided in the first groove 22, and the second protrusion 31 is provided in the second groove 23.

[0043] In the present invention, the floating member 2 is disposed in the mounting hole 11, and the mounting seat 3 is disposed in the through hole 21. When the joint assembly is installed with another joint assembly, only the floating member 2 is required as a single component to achieve adjustment in the X and Y directions. This not only simplifies the structure, reduces the number of parts and components, and reduces costs, but also improves the reliability of the joint assembly. The main body 1 is provided with a first protrusion 12, the mounting seat 3 is provided with a second protrusion 31, and the floating member 2 is provided with a first groove 22 and a second groove 23. The first protrusion 12 is disposed in the first groove 22, and the second protrusion 31 is disposed in the second groove 23. This can prevent relative rotation between the mounting seat 3 and the floating member 2, and between the floating member 2 and the main body 1, thereby increasing the reliability of the connection and reducing the relative movement between the mounting seat 3 and the main body 1 caused by battery replacement and vehicle movement, thereby reducing damage to components and extending the service life of the joint assembly.

[0044] like Figures 2 to 4As shown, the floating part 2 has an inner wall 201 and an outer wall 202, the first groove 22 is recessed inward from the outer wall 202, and the second groove 23 is recessed outward from the inner wall 201. Both the inner wall 201 and the outer wall 202 of the floating part 2 are provided with grooves, that is, an embedded structure is provided between the floating part 2 and the main body 1, and an embedded structure is also provided between the floating part 2 and the mounting seat 3, so that both the inner and outer sides of the floating part 2 are provided with embedded structures in the radial direction, which not only increases the elasticity and scalability of the floating part 2, but also prevents the relative rotation between the floating part 2 and the main body 1 and the relative rotation between the mounting seat 3 and the floating part 2 during the mating process of the joint assembly, which is not conducive to the use of the joint assembly.

[0045] like Figure 3 and Figure 4 As shown, the floating member 2 is arranged in an "8" shape. The floating member 2 is constructed of two symmetrically arranged and connected elastic rings 20. The first groove 22 and the second groove 23 are spaced apart along the radial direction of the rings 20. The rings 20 are elastic and can move in the radial direction of the rings 20 and undergo elastic deformation. When the mounting seat 3 floats, the mounting seat 3 compresses the rings 20 to move in a certain direction, thereby achieving floating installation. After installation, the rings 20 rebound to an uncompressed state. The first groove 22 and the second groove 23 are respectively provided on the inner wall 201 and the outer wall 202 of the floating member 2, so that the floating member 2 cooperates well with the main body 1 and the mounting seat 3, does not affect the floating of the joint assembly during installation, and can prevent relative rotation between the floating member 2 and the main body 1, and between the mounting seat 3 and the floating member 2.

[0046] like Figure 4 As shown, the first grooves 22 are evenly spaced along the outer wall 202 in the circumferential direction of the ring 20, and the second grooves 23 are evenly spaced along the inner wall 201 in the circumferential direction of the ring 20. The first grooves 22 are evenly spaced along the outer wall 202 in the circumferential direction of the ring 20, and the second grooves 23 are evenly spaced along the inner wall 201 in the circumferential direction of the ring 20. This not only increases the uniformity and reliability of the connection, but also when the ring 20 is subjected to pressure or tension, the connection between the ring 20 and the main body 1 and the mounting seat 3 is evenly stressed, and damage to the floating part 2 due to uneven stress will not be caused.

[0047] like Figures 3 and 4As shown, the connection line between the first groove 22 and the axis of the ring 20 is not collinear with the connection line between the second groove 23 and the axis of the ring 20, and the connection lines between the first groove 22 and the second groove 23 and the axis are not collinear. When the ring 20 is under pressure, tension or twisting, because they are not collinear, there is a certain thickness between the inner wall 201 and the outer wall 202 of the ring 20. The deformation of the first groove 22 will not cause too much impact on the second groove 23. Similarly, the deformation of the second groove 23 will not cause too much impact on the first groove 22, thereby increasing the stability and reliability of the connection, and also extending the service life of the joint assembly.

[0048] Reference Figure 3 The circular ring 20 of the present invention is provided with a plurality of through cavities 24, and the through cavities 24 penetrate the circular ring 20. The through cavities 24 and the first groove 22 are radially spaced apart and / or the through cavities 24 and the second groove 23 are radially spaced apart. In this embodiment, the through cavities 24 and the first groove 22 can be radially spaced apart and the through cavities 24 and the second groove 23 can be radially spaced apart, or only the through cavities 24 and the first groove 22 can be radially spaced apart, or only the through cavities 24 and the second groove 23 can be radially spaced apart. The provision of multiple through cavities 24 can not only reduce the overall material consumption of the floating part 2 and reduce the cost, but also improve the elasticity of the floating part 2 without reducing the strength of the floating part 2, and further change the stress distribution.

[0049] Reference Figures 3 and 4 A first notch 25 is provided at the connection between the two circular rings 20. The first notch 25 communicates with the two through-holes 21 of the floating member 2. Providing the first notch 25 between the two circular rings 20 improves the elasticity of the floating member 2 and modifies the stress of the floating member 2. It also facilitates the installation of the floating member 2 and the mounting seat 3, improving installation convenience. A second notch 26 is provided on the circular ring 20. The second notch 26 is located away from the first notch 25 in the direction of the axis line L connecting the two circular rings 20. The second notch 26 is provided on the edge of the circular ring 20. This notch increases the elasticity of the floating member 2 while enlarging the installation opening of the floating member 2, making it easier to install the mounting seat 3 into the through-hole 21, saving assembly time and improving assembly efficiency.

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

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.
