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, it will dissipate a large amount of heat during operation. Usually, a set of dedicated water-cooling pipelines are used in the battery pack to control the temperature of the battery. With the increasing requirements for the power and cruising range of new energy vehicles from the outside world, the volume of the battery module is also getting larger and larger, making the layout conditions of the water-cooling pipelines higher. The traditional cooling system is provided with a vehicle-end water quick connector on the vehicle body and a pack-end water quick connector on the battery pack, and 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 assembly process of the vehicle-end water quick connector and the pack-end water quick connector, the vehicle-end water quick connector realizes the absorption of tolerance through its own floating mechanism, but the floating mechanism has limited tolerance absorption ability in the horizontal direction. When the tolerance is large or the volume of the battery pack is large, the assembly cannot be well realized.

[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 type of connector that can increase the tolerance absorption ability and improve the assembly compatibility.

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

[0006] A fixing plate, including a mounting hole and a through hole;

[0007] A mounting part, arranged in the mounting hole, and the mounting part includes a connecting pipeline and a plugging part;

[0008] A floating mechanism, arranged in the through hole, and the floating mechanism includes a floating part and an elastic part. The floating part can move in the through hole, and the elastic part is arranged between the floating part and the inner wall of the through hole;

[0009] Wherein, the fixing plate includes a first side arranged along a first direction and a second side arranged along a second direction, the first direction is perpendicular to the second direction, and the distance that the floating part can move in the through hole along the first direction is greater than the distance that it can move along the second direction.

[0010] In the case of adopting the above technical solution, the floating member of the joint of the present utility model can move within the through hole, thereby realizing the alignment installation of the joint with other joints. The moving distance of the floating member along the first side within the through hole is greater than that along the second side, that is, the moving distance of the first side is increased, which can increase the ability of the first side to absorb tolerances. At the same time, since the first side has a greater ability to absorb tolerances, in the case of needing to increase the size of the fixing plate, a harsher use environment requiring a larger tolerance, or a larger battery pack volume requiring a larger tolerance, the compatibility of the battery can be increased.

[0011] In the preferred technical solution of the above joint, the through hole includes a first distance provided on the first side and a second distance provided on the second side, and the first distance is greater than the second distance.

[0012] In the case of adopting the above technical solution, the maximum sizes of the through hole on the first side and the second side are not equal, that is, the first distance is greater than the second distance, which can enable the floating mechanism to have a greater moving distance on the first side, thereby increasing the ability to absorb tolerances on the first side.

[0013] In the preferred technical solution of the above joint, the through hole is provided around the mounting hole and is arranged in an oval shape.

[0014] In the case of adopting the above technical solution, the through hole is provided around the mounting hole, which is convenient for the installation and movement of the floating member, and while not affecting the installation of the installation part, it is beneficial to maintain the stability of the floating of the joint.

[0015] In the preferred technical solution of the above joint, the floating member includes a first blocking portion, a second blocking portion, and a connecting portion provided between the first blocking portion and the second blocking portion. The first blocking portion and / or the second blocking portion is provided outside the through hole, and the connecting portion is provided inside the through hole.

[0016] In the case of adopting the above technical solution, the first blocking portion and the second blocking portion are provided outside the through hole, and the connecting portion is provided inside the through hole. The movement of the floating member can be realized by the movement of the connecting portion within the through hole.

[0017] In the preferred technical solution of the above joint, the elastic member is sleeved on the connecting portion and is provided inside the through hole.

[0018] In the case of adopting the above technical solution, the elastic member is sleeved on the connecting portion. When the connecting portion moves within the through hole, it will drive the elastic member to move together, which can not only limit the excessive movement of the floating member, but also play a role of elastic reset.

[0019] In the preferred technical solution of the above joint, the elastic member is a spherical spring.

[0020] In the case of adopting the above technical solution, the spherical spring can enable the floating member to reset after moving in the horizontal direction.

[0021] In the preferred technical solution of the above joint, the horizontal projection of the first blocking portion and / or the second blocking portion is greater than the horizontal projection of the through hole along the first direction and / or the second direction.

[0022] In the case of adopting the above technical solution, the horizontal projection of the first blocking portion and / or the second blocking portion is greater than the horizontal projection of the through hole along the first direction and / or the second direction, that is, the first blocking portion and / or the second blocking portion is larger than the size of the through hole, so that the floating member can be recycled multiple times without causing the first blocking portion and the second blocking portion to fall into the through hole, thereby causing damage to the floating member or the elastic member.

[0023] In the preferred technical solution of the above joint, the floating member further includes a bolt hole that penetrates the connecting portion and connects to the vehicle body or the battery pack.

[0024] In the case of adopting the above technical solution, the bolt hole is for a fixing bolt to pass through, thereby fixing the floating member to the vehicle body or the battery pack.

[0025] In a second aspect, the present invention provides a cooling system, including the joint described in the first aspect.

[0026] In a third aspect, the present invention provides an electrical device, including the cooling system described in the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The preferred implementation manners of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners 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.

[0038] It should be noted that in the description of the present utility model, the terms indicating the direction or positional relationship such as "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc. are based on the direction or positional relationship shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] 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.

[0040] As Figures 1 to 3 shown, in the first aspect, the joint of the present utility model includes a fixing plate 1, an installation part 2 and a floating mechanism. The fixing plate 1 is generally in the shape of a rectangular flat plate. The fixing plate 1 includes an installation hole 11 and a through hole 12 spaced from the installation hole 11. The installation part 2 is arranged in the installation hole 11. The installation part 2 includes a connecting pipe 21 and a plugging part 22. The floating mechanism is arranged in the through hole 12. The floating mechanism includes a floating member 3 and an elastic member 4. The floating member 3 can move in the through hole 12. The elastic member 4 is arranged between the floating member 3 and the inner wall of the through hole 12. Wherein, the fixing plate 1 includes a first side arranged along the first direction X and a second side arranged along the second direction Y. The first direction X is perpendicular to the second direction Y. The distance that the floating member 3 can move in the through hole 12 along the first direction X is greater than the distance that it can move along the second direction Y.

[0041] The floating member 3 of the joint of the present utility model can move within the through hole 12, thereby achieving the alignment installation of the joint with other joints. The moving distance of the floating member 3 along the first direction X within the through hole 12 is greater than the moving distance along the second direction Y. That is, by increasing the moving distance in the first direction X, the ability to absorb tolerances in the first direction Y can be increased. At the same time, due to the greater tolerance absorption ability in the first direction X, in cases where it is necessary to increase the size of the fixing plate 1, a harsher usage environment requires a larger tolerance, or the battery pack has a larger volume and thus requires a larger tolerance, the compatibility of the battery can be increased.

[0042] As Figure 2 shown, in the embodiment of the present utility model, the first side is the length direction of the fixing plate 1, that is, the direction in which the length of the rectangular fixing plate 1 is longer, and the second side is the width direction of the fixing plate 1. The moving distance of the floating member 3 in the first direction X is greater than the moving distance in the second direction Y. That is, the moving distance of the floating member 3 in the length direction of the fixing plate 1 is greater than the moving distance in the width direction of the fixing plate 1. In this way, the tolerances in the length direction of the fixing plate 1 can be better absorbed, enabling the battery to have better compatibility. The through hole 12 is provided around the mounting hole 11 and is elliptically arranged. In this embodiment, the number of through holes 12 is 4, and they are located at the four corners of the fixing plate 1. The through hole 12 is provided around the mounting hole 11, facilitating the installation and movement of the floating member 3. While not affecting the installation of the mounting portion 2, it is beneficial to maintain the stability of the joint floating.

[0043] Referring to Figures 2 to 3 , the through hole 12 includes a first distance m provided on the first side and a second distance n provided on the second side. The first distance m is greater than the second distance n. In this embodiment, the through hole 12 is generally elliptical, that is, the first distance m is the major axis of the ellipse, and the second distance n is the minor axis of the ellipse. The maximum dimensions of the through hole 12 on the first side and the second side are not equal, that is, the first distance m is greater than the second distance n, which can enable the floating mechanism to have a larger moving distance on the first side, thereby increasing the ability to absorb tolerances on the first side.

[0044] Referring to Figure 1 and Figure 3, the floating member 3 includes a first blocking portion 31, a second blocking portion 33, and a connecting portion 32 disposed between the first blocking portion 31 and the second blocking portion 33. The first blocking portion 31 and / or the second blocking portion 33 is disposed outside the through hole 12, and the connecting portion 32 is disposed inside the through hole 12. The movement of the floating member 3 can be achieved by the movement of the connecting portion 32 inside the through hole 12. The horizontal projection of the first blocking portion 31 and / or the second blocking portion 33 is larger than the horizontal projection of the through hole 12 along the first side and / or the second side. In this embodiment, it can be that the first blocking portion 31 and the second blocking portion 33 are larger than the size of the through hole 12 along the first side or the second side, or the first blocking portion 31 and the second blocking portion 33 are larger than the size of the through hole 12 along the first side and the second side, or the first blocking portion 31 or the second blocking portion 33 is larger than the size of the through hole 12 along the first side or the second side, or the first blocking portion 31 or the second blocking portion 33 is larger than the size of the through hole 12 along the first side and the second side. This enables the floating member 3 to be repeatedly used in a reciprocating cycle, preventing the first blocking portion 31 and the second blocking portion 33 from falling into the through hole 12, which may otherwise damage the floating member 3 or the elastic member 4 and affect the reliability of the joint in use.

[0045] Referring to Figure 1 and Figure 3 , the floating member 3 further includes a bolt hole 34 penetrating through the connecting portion 32. The bolt hole 34 is for a fixing bolt to pass through, thereby fixing the floating member 3 to the vehicle body or the battery pack. The elastic member 4 is sleeved on the connecting portion 32 and is disposed inside the through hole 12. The elastic member 4 is sleeved on the connecting portion 32. When the connecting portion 32 moves inside the through hole 12, the elastic member 4 will move along with it. This can not only limit the excessive movement of the floating member 3 but also play a role in elastic reset. The elastic member 3 is a spherical spring, which enables the floating member 3 to be reset in the horizontal direction after moving in the horizontal direction. In this embodiment, it can move and reset independently in the X direction, or independently in the Y direction, or move and reset simultaneously in the X direction and the Y direction.

The cooling system of this technical solution includes the joint of 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.

[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 it has all the technical effects of the cooling system of any technical solution of the present utility model.
