Technical Field

[0001] This invention relates to the field of electric vehicle charging technology, and in particular to a flexible charging connection device and charging equipment. Background Technology

[0002] With the large-scale promotion and application of new energy electric vehicles, the demand for charging infrastructure, especially fully automatic charging devices, is becoming increasingly urgent. Existing fully automatic charging devices have AC and DC charging interfaces with a certain degree of flexible connection, which facilitates the adjustment of the charging angle.

[0003] Existing charging interfaces have numerous components, especially the large number of springs used to achieve a smooth connection. This makes assembly inconvenient, increases the risk of high-voltage breakdown, and limits their load-bearing capacity. For DC charging interfaces in particular, larger springs and a greater number of springs are needed to handle higher loads. Summary of the Invention

[0004] This invention provides a flexible charging connection device and charging equipment, which solves the problems of inconvenient charging interface assembly and inability to withstand large loads.

[0005] On one hand, embodiments of the present invention provide a flexible charging connection device, including a first support portion and a second support portion sleeved within the first support portion. The second support portion and the first support portion are spherically rotatable. The first end of the first support portion has an opening, and the first end of the second support portion also has an opening. A docking portion is provided inside the second support portion for connecting a charging plug. The docking portion faces the opening at the first end of the second support portion. A limiting portion is provided on the second support portion to limit the range of spherical rotation of the second support portion relative to the first support portion, so that the docking portion is located within the opening range of the first end of the first support portion.

[0006] According to one aspect of the present invention, the limiting portion includes a limiting groove disposed on the outer side of the second support portion; a limiting pin is disposed on the first support portion, the bottom end of the limiting pin extending into the limiting groove, so that the mating portion is located within the opening range of the first end of the first support portion.

[0007] According to one aspect of the present invention, the limiting portion includes a limiting stop ring disposed at the opening of the first end of the second support portion, and the limiting stop ring protrudes from the outer side of the second support portion so that the opening of the first end of the second support portion is located within the opening range of the first end of the first support portion.

[0008] According to one aspect of the present invention, the first support portion is annular, and the inner surface of the first support portion is spherical.

[0009] According to one aspect of the present invention, the second support portion is annular, the outer surface of the second support portion is spherical, the outer surface of the second support portion matches the inner surface of the first support portion, and the second support portion is capable of spherical rotation within the first support portion.

[0010] According to one aspect of the present invention, the first support portion includes a first support clamp and a second support clamp that are mated to each other; the first support clamp has a first spherical surface that extends to both sides of the first support clamp; the second support clamp has a second spherical surface that matches and corresponds to the first spherical surface.

[0011] According to one aspect of the present invention, the device further includes a mounting frame, wherein a first support portion is movably connected to a first end of the mounting frame, and the first support portion is capable of translation and rotation relative to the mounting frame.

[0012] According to one aspect of the present invention, the second end of the first support portion has an opening, and the second end of the second support portion is provided with an elastic limiting member; one end of the elastic limiting member is connected to the second end of the second support portion, and the other end of the elastic limiting member passes through the opening of the second end of the first support portion and is connected to the second end of the mounting bracket, so that the second support portion can be reset after rotating relative to the spherical surface of the mounting base.

[0013] According to one aspect of the present invention, an elastic limiting member is provided between the second end of the second support portion and the second end of the first support portion, so that the second support portion can be reset after rotating relative to the spherical surface of the first support portion.

[0014] On the other hand, embodiments of the present invention provide a charging device, including the flexible charging connection device as described above.

[0015] The flexible charging connection device provided in this embodiment of the invention allows for spherical rotation between the second support part and the first support part, and the position of the docking part is flexibly adjustable. At the same time, the range of spherical rotation of the second support part is limited by the limiting part to ensure that the docking part is in a position that can be connected. When the charging plug is in a certain deflection position, the docking part is connected to the charging plug by adjusting the spherical rotation of the second support part relative to the first support part, achieving a smooth connection effect.

[0026] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0027] In the description of this invention, it should be noted that, unless otherwise stated, the terms "first" and "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance; "a plurality of" means two or more; the terms "inner," "outer," "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0028] Please see Figure 1 and Figure 2 The flexible charging connection device of this invention includes a first support portion 100 and a second support portion 200 sleeved within the first support portion 100. The second support portion 200 and the first support portion 100 are spherically rotatable. The first support portion 100 has an opening at its first end, and the second support portion 200 also has an opening at its first end. A docking portion 300 is provided inside the second support portion 200 for connecting a charging plug 600. The docking portion 300 faces the opening at the first end of the second support portion 200. A limiting portion is provided on the second support portion 200 to limit the range of spherical rotation of the second support portion 200 relative to the first support portion 100, so that the docking portion 300 is located within the opening range of the first end of the first support portion 100. In this embodiment, the second support 200 and the first support 100 can rotate spherically, and the position of the docking part 300 is flexibly adjustable. At the same time, the range of spherical rotation of the second support 200 is limited by the limiting part to ensure that the docking part 300 is in a position that can be connected. When the charging plug 600 is in a certain deflection position, the docking part 300 and the charging plug 600 are connected by adjusting the spherical rotation of the second support 200 relative to the first support 100, achieving a smooth connection effect. The overall structure of the device is simple and easy to assemble. At the same time, it avoids the use of a large number of springs, which makes it less likely to cause high voltage breakdown. It can improve the load-bearing capacity and is suitable for application scenarios with high power charging requirements. It solves the problems of inconvenient assembly and inability to withstand large loads of existing charging interfaces.

[0029] The docking part 300 has an electrical connection interface that matches the charging plug 600. After the charging plug 600 is connected to the electrical connection interface of the docking part 300, charging can be achieved.

[0030] Furthermore, the docking part 300 may be provided with a guide hole 201 for cooperating with a guide that may be present on the charging plug 600, making the connection between the charging plug 600 and the docking part 300 more convenient.

[0031] As an optional embodiment, the limiting part includes a limiting groove, which is disposed on the outer side of the second support part 200; a limiting pin 701 is provided on the first support part 100, and the bottom end of the limiting pin 701 extends into the limiting groove so that the mating part 300 is located within the opening range of the first end of the first support part 100.

[0032] In this embodiment, the limiting groove cooperates with the limiting pin 701 to limit the range of spherical rotation of the second support part 200 relative to the first support part 100, ensuring that the docking part 300 can be connected to the charging plug 600, and especially limiting the axial rotation of the second support part 200. Correspondingly, the limiting groove is partially distributed in the circumferential direction of the second support part 200, that is, it is not a circumferential groove, which limits the second support part 200 from rotating completely around its own circumference. At the same time, the limiting groove should have a certain width to provide a certain degree of freedom for the non-axial rotation of the second support part 200.

[0033] As an optional embodiment, the limiting part includes a limiting ring 702, which is disposed at the opening at the first end of the second support part 200. The limiting ring 702 protrudes from the outer surface of the second support part 200 so that the opening at the first end of the second support part 200 is located within the opening range of the first end of the first support part 100.

[0034] The limiting ring 702 protruding from the outer side of the second support portion 200 in this embodiment restricts the range of spherical rotation of the second support portion 200 relative to the first support portion 100. When the limiting ring 702 contacts the opening at the first end of the first support portion 100, the second support portion 200 cannot continue to move in the same direction. This makes the opening at the first end of the second support portion 200 located within the opening range of the first end of the first support portion 100, thereby making the docking portion 300 located within the opening range of the first end of the first support portion 100, ensuring that the docking portion 300 can be connected to the charging plug 600.

[0035] It is understandable that the structure of the limiting ring 702 and the structure of the limiting groove and the limiting pin 701 can exist separately or be set at the same time to limit the spherical rotation range of the second support 200.

[0036] As an optional embodiment, the first support portion 100 is annular, and the inner surface of the first support portion 100 is spherical.

[0037] As an optional embodiment, the second support portion 200 is annular, and the outer surface of the second support portion 200 is spherical. The outer surface of the second support portion 200 matches the inner surface of the first support portion 100, and the second support portion 200 can rotate spherically within the first support portion 100.

[0038] In this embodiment, the annular second support portion 200 is disposed within the annular first support portion 100, and the surfaces of the two facing each other are spherical, so that the second support portion 200 can rotate spherically relative to the first support portion 100. The structure is simple and easy to form.

[0039] Combination Figure 3As an optional embodiment, the first support portion 100 includes a first support clamp 101 and a second support clamp 102 that are connected to each other; the first support clamp 101 has a first spherical surface that extends to both sides of the first support clamp 101; the second support clamp 102 has a second spherical surface that matches and corresponds to the first spherical surface.

[0040] In this embodiment, the first spherical surface extends to both sides of the first support plate 101, that is, the first support plate 101 has a through hole, and the wall of the through hole is spherical; the second support plate 102 has a second spherical surface, and the second support plate 102 may have a through hole or a groove structure. For the through hole, its wall is spherical and matches and corresponds to the first spherical surface. For the groove structure, its inner wall is spherical and matches and corresponds to the first spherical surface.

[0041] In this embodiment, the first support clamp 101 and the second support clamp 102 are connected to clamp the second support part 200 in the spherical space formed by the first spherical surface and the second spherical surface, realizing the spherical connection between the second support part 200 and the first support part 100. The side of the first support clamp 101 facing away from the second support clamp 102 serves as the first end of the first support. The opening of the first end of the second support part 200 faces the side of the first support clamp 101 facing away from the second support clamp 102, so that the second support part 200 can be spherically rotated in all directions relative to the first support part 100. At the same time, the docking part 300 is located within the opening range of the first end of the first support part 100.

[0042] The first support clamp 101 and the second support clamp 102 can be fixedly connected after the second support part 200 is installed. The specific connection method is not limited and can be adhesive bonding.

[0043] As an optional embodiment, it also includes a mounting bracket 400, with a first support portion 100 movably connected to a first end of the mounting bracket 400, and the first support portion 100 being able to translate and rotate relative to the mounting bracket 400.

[0044] In this embodiment, the first support part 100 is movably connected to the mounting bracket 400, enabling the first support part 100 to perform a certain degree of planar movement and planar rotation, so that the second support part 200 can also perform a certain degree of planar movement and planar rotation. Thus, the docking part 300 can perform planar movement and planar rotation on the basis of spherical rotation, resulting in a better smooth connection effect.

[0045] The mounting bracket 400 may be provided with a mounting groove, and the outer side of the first support part 100 may be provided with a mounting ring that matches the mounting groove. The mounting groove and the mounting ring cooperate to realize the movable connection between the first support part 100 and the mounting bracket 400. Furthermore, a damping element 202 may be provided in the mounting groove to buffer the planar movement of the first support part 100, so that the planar movement of the first support part 100 is more stable. Specifically, the damping element 202 may be made of rubber material.

[0046] As an optional embodiment, the second end of the first support portion 100 has an opening, and the second end of the second support portion 200 is provided with an elastic limiting member 500; one end of the elastic limiting member 500 is connected to the second end of the second support portion 200, and the other end of the elastic limiting member 500 passes through the opening at the second end of the first support portion 100 and is connected to the second end of the mounting bracket 400, so that the second support portion 200 can be reset after rotating relative to the spherical surface of the mounting base.

[0047] In this embodiment, the elastic limiting member 500 is disposed between the second end of the second support portion 200 and the second end of the mounting bracket 400. The elastic limiting member 500 can buffer the movement of the second support portion 200, including spherical rotation, planar movement and planar rotation, so that the movement of the second support portion 200 is more stable. On the other hand, it can reset the second support portion 200 after moving relative to the mounting base. This movement also includes spherical rotation, planar movement and planar rotation, which facilitates the reuse of the docking portion 300. Specifically, the elastic limiting member 500 can be a bellows spring or a conventional helical spring.

[0048] The second end of the first support portion 100 may be the end that corresponds to its first end in the axial direction, that is, the second end of the first support portion 100 and the first end are located on the same axis; the second end of the mounting bracket 400 may be the end that corresponds to its first end in the aforementioned axial direction.

[0049] As an optional embodiment, an elastic limiting member 500 is provided between the second end of the second support portion 200 and the second end of the first support portion 100, so that the second support portion 200 can be reset after rotating spherically relative to the first support portion 100.

[0050] In this embodiment, the elastic limiting member 500 also serves to buffer the movement of the second support portion 200 and to reset the second support portion 200 after movement. It can be understood that the spherical space of the first support portion 100 should be sufficient for the setting of the elastic limiting member 500, and that the elastic limiting member 500 can perform the aforementioned functions.

[0051] Please see Figure 4When the charging plug 600 is connected to the docking part 300 at a certain deflection position, the docking part 300 can still smoothly dock with the charging plug 600 through spherical rotation, planar movement and planar rotation, achieving a smooth connection effect.

[0052] This invention also provides a charging device, including the flexible charging connection device as described in the previous embodiment. The charging device in this embodiment can take various forms such as a charging pile, and can achieve a smooth connection with the charging plug 600. It is convenient to use, stable in operation, and highly safe. It is suitable for application scenarios with high power charging requirements and has value for promotion and application.

[0053] Those skilled in the art will understand that the above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
