The corresponding new energy vehicle charging technology has also been further improved and developed, playing an important role in the large-scale promotion and application of new energy vehicles.

[0003] Among them, charging piles are commonly used equipment for charging electric vehicles. There are two installation methods: floor-standing type and wall-mounted type. However, since both adopt fixed installation methods, each parking space needs to be equipped with a charging pile, which easily causes the charging piles to be idle and waste resources.

DETAILED DESCRIPTION

[0030] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If the terms "first" or "second" are described, they are only used for descriptive purposes and cannot be understood to indicate or imply relative importance.

[0033] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" 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 or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] See also Figures 1 to 5A mobile power connection assembly includes: a power connection rail 100 and a mounting seat 200, wherein the power connection rail 100 is used to be fixed to a frame 400, the power connection rail 100 is provided with a metal conduit 110, the metal conduit 110 is used to connect an external power supply, and the metal conduit 110 is provided with at least three card slots 111; the mounting seat 200 is movably provided on the power connection rail 100, the mounting seat 200 is used to install a charging cabinet 500 that can be moved relative to the frame 400, and the mounting seat 200 is detachably provided with At least three mounting shells 300 are provided, each mounting shell 300 is movably provided with a conductive member 310, and the three conductive members 310 are respectively detachably connected to the neutral wire, the live wire and the ground wire of the charging cabinet 500, and an elastic member 320 is detachably connected between the mounting shell 300 and the conductive member 310, and the elastic member 320 is used to drive the conductive member 310 to move to be engaged with the corresponding card slot 111, and the mounting shell 300 is provided with a limiting structure, and the limiting structure has a locking state and an unlocking state for changing the deformation amount of the elastic member 320.

[0035] The movable power connection assembly of the above structure, when installed, the limiting structure is in a locked state, and the conductive member 310 retracts relative to the installation shell 300, so that the three conductive members 310 can be aligned with the corresponding slots 111 first, which is conducive to reducing the steps that people need to press the conductive member 310 to simplify the installation difficulty, and then the limiting structure is switched from the locked state to the unlocked state, so that the elastic member 320 recovers the deformation to drive the conductive member 310 to extend out of the installation shell 300, so that the conductive member 310 is always connected to the corresponding slot 111, thereby ensuring that the conductive member 310 is always in contact with the metal conduit 110, and then the conductive member 310 and the power connection slide rail 100 are completed. The above structure is adopted, not only the power connection is stable, but also the alignment difficulty of the conductive member 310 is simplified with the limiting structure, so as to simplify the installation difficulty and manufacturing cost.

[0036] It is understandable that the three conductive members 310 are independently installed on the mounting base 200, which is conducive to staggering the installation positions of the three conductive members 310, thereby avoiding the influence and entanglement between the power supply lines of the charging cabinet 500, and is also conducive to the subsequent separate disassembly of the corresponding conductive members 310 for maintenance, thereby improving people's use experience. It is understandable that the metal tube is a copper tube, and the copper tube is integrally formed with a plurality of card slots 111, and the conductive member 310 can be a carbon brush head or a copper block, which will not be described in detail.

[0037] See also Figures 2 to 4, further, the mounting shell 300 is connected to the mounting seat 200 through a first bolt member, the mounting shell 300 is provided with a mounting groove 301, the side wall of the mounting groove 301 is provided with a guide hole for the conductive member 310 to move, one end of the elastic member 320 is connected to the side wall of the mounting groove 301, the other end of the elastic member 320 is connected to a mounting plate 321, and the mounting plate 321 is connected to the conductive member 310 through a second bolt member. Specifically, the conductive member 310 has two planes that match the inner wall of the guide hole, so that the conductive member 310 can be translated relative to the mounting shell 300 by plane contact, and further ensure that the elastic member 320 drives the conductive member 310 to press against the inner wall of the card slot 111. Among them, the elastic member 320 can adopt a compression spring, or other plastic and rubber parts with elastic deformation ability, which will not be described in detail.

[0038] See also Figure 5Further, the limiting structure includes a limiting plate 340 rotatably arranged on the mounting shell 300, the limiting plate 340 is coaxially provided with a ratchet 341, the mounting shell 300 is elastically connected with a non-return pawl 342, the non-return pawl 342 cooperates with the ratchet 341, and the non-return pawl 342 is used to limit the reverse rotation of the limiting plate 340, the limiting plate 340 rotates to abut against the mounting plate 321, and the conductive member 310 retracts into the mounting slot 301. Among them, due to the difference in processing between the card slot 111 and the mounting slot 301, it is easy to have a situation where the extended length of the conductive member 310 is greater than the depth of the card slot 111, so that people need to press the conductive member 310 to retract into the mounting slot 301, thereby increasing the difficulty of aligning and installing multiple conductive members 310. Specifically, the mounting shell 300 is bolted with a flat plate 350, and the limiting mechanism includes a rotating shaft 343400 rotatably arranged on the flat plate 350, the rotating shaft 343 is coaxially connected to the ratchet 341, the non-returning ratchet 342 is built with a coil spring for limiting its reverse rotation, and the limiting plate 340 is arranged at one end of the rotating shaft 343, the limiting plate 340 is built in the mounting shell 300, and the limiting plate 340 abuts against the mounting plate 321 to keep the conductive member 310 retracted relative to the mounting shell 300. Among them, the other end of the rotating shaft 343 is provided with an auxiliary plate 344 colinear with the limiting plate 340, and people judge the position of the limiting plate 340 by rotating the auxiliary plate 344. Among them, when the indexing plate is rotated to a horizontal position, the elastic member 320 recovers its deformation to drive the mounting plate 321 to pass through the limiting plate 340, so that the conductive member 310 can extend out of the mounting shell 300 and be clamped in the clamping slot 111. When the limit plate 340 rotates to a non-horizontal position, the mounting plate 321 is located between the limit plate 340 and the side wall of the mounting groove 301, so that the elastic member 320 drives the mounting plate 321 to abut against the limit plate 340. The limit plate 340 cannot be reversed under the cooperation of the ratchet 341 and the non-return pawl 342, thereby keeping the conductive member 310 retracted relative to the mounting shell 300, which is conducive to reducing the steps of manual pressing required by people when installing the conductive member 310, thereby improving people's use experience. It can be understood that if the ratchet 341 rotates in a clockwise direction, the non-return pawl 342 slides on the back of the teeth of the ratchet 341. When the elastic member 320 drives the mounting plate 321 to move to abut against the limit plate 340, the limit plate 340 has a tendency to rotate counterclockwise, and the non-return pawl 342 prevents the ratchet 341 from rotating counterclockwise through the coil spring, thereby achieving the effect of keeping the conductive member 310 retracted relative to the mounting shell 300.

[0039] See also Figure 2 and Figure 4Furthermore, the side wall of the installation groove 301 is provided with a convex strip, the length direction of the convex strip is parallel to the axis of the guide hole, and the conductive member 310 is provided with a groove 311 that slidably cooperates with the convex strip, thereby avoiding deflection during the movement of the conductive member 310, which is conducive to regulating the translational movement of the conductive member 310 relative to the installation shell 300. In some embodiments, the installation groove 301 is built with a guide column, and the conductive member 310 is provided with a through hole that cooperates with the conductive member 310. The through hole and the guide column are slidably cooperated, which can also regulate the translational movement of the conductive member 310.

[0040] See also Figure 2 and Figure 3 Furthermore, the power supply rail 100 is provided with a rectangular cavity 101, and the mounting seat 200 is rotatably provided with a first roller 201, and the first roller 201 is in rolling contact with the inner bottom wall of the cavity 101, thereby reducing the friction of the movement of the mounting seat 200, which is conducive to improving the smoothness of the movement of the charging mounting seat 200. Among them, the mounting seat 200 is a plate body arranged parallel to the axis of the cavity 101, and the plate body is provided with a plurality of mounting holes 203. The number of mounting holes 203 corresponds to the power supply line of the charging cabinet 500. Each mounting hole 203 is correspondingly provided with a mounting shell 300. The first roller 201 is arranged on the mounting seat 200, so that the mounting seat 200 can provide a position for the charging cabinet 500 to be installed and connected to the power supply rail 100. The overall structure is simple, which is conducive to simplifying the subsequent installation difficulty and manufacturing cost of the charging cabinet 500. It is understandable that the mounting base 200 is provided with a waist-shaped groove 204, and the bottom wall of the waist-shaped groove 204 is provided with multiple perforations at intervals, each perforation corresponds to the power supply line of the charging cabinet 500, so as to separate the multiple power supply lines of the charging cabinet 500.

[0041] See also Figure 2 and Figure 3 Furthermore, the power-connecting slide rail 100 is provided with a long hole 102 for the mounting seat 200 to pass through, and the power-connecting slide rail 100 is relatively provided with two vertical plates 120, and the upper ends of the vertical plates 120 are connected to the side walls of the long hole 102. The mounting seat 200 is rotatably provided with a second roller 202, and the second roller 202 abuts between the two vertical plates 120, so that the second roller 202 is used to guide and limit the movement of the mounting seat 200, and further improves the smoothness of the movement of the mounting seat 200.

[0042] See also Figure 2 and Figure 4 Furthermore, the mounting seat 200 is provided with a plurality of mounting holes 203, the mounting shell 300 is built into the mounting holes 203, the mounting shell 300 is provided with a side extension plate 302, and the first bolt member is provided on the side extension plate 302, so as to facilitate independent installation or removal of the mounting shell 300.

[0043] See also Figure 4Furthermore, a mounting sleeve 303 is provided on the inner wall of the mounting groove 301, and the elastic member 320 is a spring mounted on the mounting sleeve 303, thereby regulating the deformation direction of the spring.

[0045] S1, the three conductive members 310 are respectively connected to the neutral line, the live line and the ground line of the charging cabinet 500, and the three conductive members 310 are independently installed on the mounting seat 200, the limiting structure is in a locked state, and the conductive members 310 are retracted into the mounting shell 300;

[0048] S4, connecting the power supply rail 100 to an external power supply, moving the charging cabinet 500, and the metal conduit 110 and the conductive member 310 are always in contact to form a mobile power supply.

[0049] A method for using a mobile power connection assembly according to an embodiment of the present invention has at least the following beneficial effects: through the above steps, the conductive member 310 contacts the power connection rail 100, so that the charging cabinet 500 can achieve mobile power connection relative to the frame 400, which not only makes the power connection stable, but also eliminates the existing wire collection structure and reduces the length of the cable layout, which is conducive to simplifying the installation difficulty and cost of the charging cabinet 500.
