[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0038] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a magnetic quick connection device, which includes a fixing unit 100 and a conductive unit 200.

[0039] The fixing unit 100 includes a mounting cover 101 and a magnetic ring 102 disposed inside the mounting cover 101 .

[0040] The conductive unit 200 includes a conductive block 201 disposed inside the mounting cover 101 and a wire 202 connected to the conductive block 201 , wherein the bottom of the conductive block 201 is flush with or exceeds the bottom of the magnetic ring 102 .

[0041] During use, by contacting the magnetic ring 102 with the terminal connector to be connected, the magnetic ring 102 will automatically connect with the terminal connector under the action of magnetic force, so that the mounting cover 101 can be quickly and accurately adsorbed on the terminal connector. At this time, the conductive block 201 will automatically release the conductive contact to achieve circuit connectivity.

[0042] Example 2, reference Figure 2-Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the fixing unit 100 also includes a conductive seat 103, and the conductive seat 103 cooperates with the magnetic ring 102 and the conductive block 201; when the magnetic ring 102 and the conductive seat 103 are close to each other, they will be adsorbed on the conductive seat 103, and at this time, the conductive block 201 will contact the conductive seat 103 for conduction.

[0043] The mounting cover 101 is in a convex shape; the conductive block 201 includes a fixing ring 201a disposed on the upper portion of the mounting cover 101, a connecting cover 201b disposed at the bottom of the fixing ring 201a, and a conductive ring 201c disposed at the bottom of the connecting cover 201b;

[0044] When the magnetic ring 102 and the conductive base 103 are close to each other, the magnetic ring 102 will be attracted to the conductive base 103. At this time, the conductive ring 201c is in contact with the conductive base 103 and is energized.

[0045] A limiting groove 104 is provided in the conductive base 103 , a connecting component 203 and a limiting component 204 arranged at the bottom of the connecting component 203 are provided on the conductive wire 202 ; the limiting component 204 matches with the limiting groove 104 .

[0046] Among them, the limiting component 204 includes a mounting ring 204a arranged below the fixing ring 201a, a connecting piece 204b arranged between the mounting ring 204a and the fixing ring 201a, a plurality of support plates 204c slidably arranged in the mounting ring 204a, a connecting portion 204d arranged between the support plate 204c and the mounting ring 204a, and a limiting portion 204e arranged at the end of the support plate 204c; the bottom of the connecting component 203 is against the plurality of support plates 204c, one end of the connecting component 203 is connected to the wire 202, and the connecting component 203 is slidably connected to the fixing ring 201a, and at the same time maintains conductivity with the fixing ring 201a.

[0047] The connecting portion 204d includes a slide groove 204d-1 arranged in the support plate 204c, a slider 204d-2 slidably arranged in the slide groove 204d-1 and connected to the mounting ring 204a, and a spring 204d-3 arranged between the slide groove 204d-1 and the slider 204d-2, wherein the connecting component 203 can squeeze the support plate 204c so that the support plate 204c extends outward from the mounting ring 204a and can compress the spring 204d-3, and when the connecting component 203 is separated from the support plate 204c, under the elastic force of the spring 204d-3, the support plate 204c will retract into the mounting ring 204a and contact the connecting component 203.

[0048] The limiting groove 104 is in a convex shape, and the outlet diameter of the limiting groove 104 is smaller than the inner diameter of the cavity;

[0049] The limiting portion 204e includes a mounting seat 204e-1 arranged at the end of the support plate 204c, a limiting plate 204e-2 hingedly arranged on the mounting seat 204e-1, and a spring 204e-3 arranged between the limiting plate 204e-2 and the support plate 204c; the mounting seat 204e-1 has a triangular cross-section, and the limiting plate 204e-2 rotates to abut against the high side of the mounting seat 204e-1. Under the elastic force of the spring 204e-3, the limiting plate 204e-2 maintains a state of abutting against the high side of the mounting seat 204e-1, and at this time, the end of the limiting plate 204e-2 exceeds the end of the support plate 204c.

[0050] When the mounting ring 204a is inserted into the limit groove 104, the back side of the limit plate 204e-2 will contact the inner wall at the exit of the limit groove 104. At this time, the back side of the limit plate 204e-2 will be squeezed and rotate toward the direction of the mounting ring 204a and compress the spring 204e-3. When the limit plate 204e-2 passes through the exit of the limit groove 104 and enters the cavity of the limit groove 104, the limit plate 204e-2 pops out under the elastic force of the spring 204e-3 and abuts against the mounting seat 204e-1. At this time, when the mounting ring 204a drives the limit plate 204e-2 to exit the limit groove 104, the limit plate 204e-2 will abut against the exit of the limit groove 104, making the mounting ring 204a unable to exit, thereby making the conductive ring 201c firmly contact with the conductive seat 103 and cannot be pulled apart.

[0051] During use, the magnetic ring 102 is brought close to the conductive seat 103, and the magnetic ring 102 will be adsorbed on the conductive seat 103. At the same time, when the magnetic ring 102 and the conductive seat 103 are close to each other, the installation ring 204a will move toward the limiting groove 104, and the limiting plate 204e-2 will first move together and then open when passing through the exit of the limiting groove 104, so that the installation ring 204a is smoothly inserted into the limiting groove 104 and is restricted from withdrawing. At this time, the conductive ring 201c is in contact with the conductive seat 103 and is energized, achieving the purpose of quick connection while preventing falling off;

[0052] When the conductive ring 201c needs to be separated from the conductive seat 103, it is only necessary to control the connection assembly 203 to separate from the multiple support plates 204c, so that the multiple support plates 204c are retracted into the mounting ring 204a, thereby making the limiting plate 204e-2 located on the inner side of the exit of the limiting groove 104. At this time, the mounting ring 204a can be smoothly pulled out of the limiting groove 104, and the conductive ring 201c can be separated from the conductive seat 103.

[0053] The remaining structures are the same as those of Example 1.

[0054] Example 3, reference Figure 2-Figure 4 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the connecting component 203 includes a conductive column 203a slidably set in the fixing ring 201a, a limiting ring 203b set in the middle of the conductive column 203a, and a spring three 203c set between the limiting ring 203b and the fixing ring 201a, and a driving part 203d set at the bottom of the conductive column 203a and connected to the support plate 204c; the conductive column 203a and the fixing ring 201a are electrically conductive, and the top of the conductive column 203a passes through the installation cover 101 and is connected to the wire 202.

[0055] The driving part 203d includes an extrusion block 203d-1 disposed at the bottom of the conductive column 203a, a bottom plate 203d-2 disposed at the bottom of the extrusion block 203d-1, and a plurality of extrusion surfaces 203d-3 disposed in the extrusion block 203d-1;

[0056] The end of the support plate 204c is set as a slope, and multiple extrusion surfaces 203d-3 are respectively abutted against the multiple support plates 204c; the bottom plate 203d-2 is abutted against the mounting ring 204a, wherein when the bottom plate 203d-2 is in contact with the bottom of the mounting ring 204a, the support plate 204c is squeezed out of the mounting ring 204a by the extrusion block 203d-1, and when the bottom plate 203d-2 is separated from the bottom of the mounting ring 204a, the support plate 204c retracts under the elastic force of the spring 204d-3 and contacts the extrusion surface 203d-3.

[0057] Furthermore, the connecting member 204b is made of an elastic member or a fixing member. When the connecting member 204b is made of an elastic member, the elastic force of the elastic member is greater than the elastic force of spring three 203c, the elastic force of spring three 203c is greater than the elastic force of multiple springs one 204d-3, and the elastic force of spring two 204e-3 is less than the elastic force of the elastic member.

[0058] In the initial state, under the elastic force of spring three 203c, the conductive column 203a will drive the extrusion surface 203d-3 to squeeze the support plate 204c, so that the support plate 204c extends out of the mounting plate, and the mounting ring 204a remains stationary under the action of the connecting member 204b. When the connecting member 204b is made of an elastic member, when the bottom of the base plate 203d-2 is subjected to external force, the base plate 203d-2 and the mounting ring 204a will be squeezed to shrink in the mounting cover 101. When the connecting member 204b is made of a fixing member, when the bottom of the base plate 203d-2 is subjected to external force, the mounting ring 204a will not be squeezed to shrink in the mounting cover 101.

[0059] During use, the magnetic ring 102 is brought close to the conductive seat 103, and the magnetic ring 102 will be adsorbed on the conductive seat 103. At the same time, when the magnetic ring 102 and the conductive seat 103 are close to each other, the installation ring 204a will move toward the limiting groove 104, and the limiting plate 204e-2 will first move together and then open when passing through the exit of the limiting groove 104, so that the installation ring 204a is smoothly inserted into the limiting groove 104 and is restricted from withdrawing. At this time, the conductive ring 201c is in contact with the conductive seat 103 and is energized, achieving the purpose of quick connection while preventing falling off;

[0060] When it is necessary to separate the conductive ring 201c from the conductive seat 103, it is only necessary to squeeze the wire 202 and the conductive column 203a toward the inside of the mounting cover 101, so that the conductive column 203a and the extrusion block 203d-1 move toward the limiting groove 104. At this time, the multiple extrusion surfaces 203d-3 are separated from the multiple support plates 204c, and the multiple support plates 204c will retract into the mounting ring 204a, so that the limiting plate 204e-2 is located on the inner side of the limiting groove 104 outlet. At this time, the mounting ring 204a can be smoothly pulled out of the limiting groove 104, and the conductive ring 201c can be separated from the conductive seat 103; the mounting cover 101 and the conductive seat 103 can be disassembled only when the wire 202 moves toward the mounting cover 101, which can effectively prevent the mounting cover 101 and the conductive seat 103 from detaching when the wire 202 is pulled.

[0061] The remaining structure is the same as that of Example 2.

[0062] Example 4, reference Figure 3 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: a driving plate 202a is provided on the outside of the wire 202, a bellows 202b is provided between the driving plate 202a and the mounting cover 101; and the end of the conductive column 203a is located in the bellows 202b.

[0063] The bellows 202b has an insulating effect, and the bellows 202b can be extended and retracted as the conductive column 203a moves. When the mounting cover 101 is detached from the conductive seat 103, it is only necessary to press the drive plate 202a by hand to insert the conductive column 203a into the limit groove 104. After the multiple extrusion surfaces 203d-3 are separated from the multiple support plates 204c, the hand is in contact with the mounting cover 101 at the same time. The drive plate 202a and the mounting cover 101 are held at the same time and then pulled out to separate the mounting cover 101 from the conductive seat 103, and the connection part 204d is disassembled.

[0064] The remaining structure is the same as that of Example 3.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
