In this embodiment, the first power pickup component includes an outer shell 104 connected to the terminal block 101a, a power pickup coil 105 arranged in the outer shell 104, and a wire tube 106 arranged in the outer shell 104. The overall shape of the outer shell 104 is cylindrical.

[0042] A through hole is formed at the center of the outer shell 104, which connects the two end surfaces of the outer shell 104, and a hollow space is formed inside the outer shell 104. A power taking coil 105 is provided in the space inside the outer shell 104, and the power taking coil 105 serves to energize when connected, and the wire tube 106 connects the through holes at both ends.

[0043] In this embodiment, the first power extraction component 103 a is disposed in the terminal block 101 a , and the second power extraction component 103 b is disposed on the plug-in block 102 .

A toggle plate 305 is arranged on the first connecting post 303, and the toggle plate 305 docks with the second connecting post 304 after rotation. The outer shell 104 provided with the second connecting rod 302 is connected to the toggle plate 305, and a sliding member 400 for driving the outer shell 104 to slide is arranged on the toggle plate 305.

[0045] Preferably, a toggle plate 305 is also rotatably connected to the plug strip 102 . The toggle plate 305 is connected to the second power extraction member 103 b and drives the second power extraction member 103 b to rotate together when rotating.

[0046] In this embodiment, if Figure 6 , Figure 8 , Fig. 9 The sliding member 400 includes an arc groove 401 opened on the terminal row 101a, and the arc groove 401 is also correspondingly opened on the plug-in row 102 for movement of the second power-taking member 103b.

[0047] Furthermore, a first rotating arc plate 405 is provided in the connecting frame bottom plate 404, and a second rotating arc plate 406 and a third rotating arc plate 407 are rotatably connected on the side wall of the first rotating arc plate 405. The first rotating arc plate 405, the second rotating arc plate 406 and the third rotating arc plate 407 have the same size and the same rotating plane, and then a first inclined surface 408 is provided at the end of the first connecting rod 301 and the second connecting rod 302, and a surface block 409 is provided on the second rotating arc plate 406 and the third rotating arc plate 407. There are two surface blocks 409, and the two first inclined surfaces 408 are respectively provided in the two surface blocks 409, and a downward pressing rod 409b is slidably connected to each surface block 409, and the downward pressing rod 409b is matched with the surface block 409. A second inclined surface 409a cooperating with the first inclined surface 408 is provided on the rod 409b. When the lower pressure rod 409b slides downward, the second inclined surface 409a pushes the first inclined surface 408, causing the first connecting rod 301 and the second connecting rod 302 to slide, so that the front ends of the first connecting rod 301 and the second connecting rod 302 extend into the first power-collecting component 103a or the second power-collecting component 103b, so that the first connecting rod 301, the second connecting rod 302, the first power-collecting component 103a and the surface block 409 are connected as a whole, and the above-mentioned connection makes the first rotating arc plate 405, the second rotating arc plate 406 and the third rotating arc plate 407 connected to each other, so that at this time, it is only necessary to control the sliding of the surface block 409 to realize the common movement of the first power-collecting component 103a and the second power-collecting component 103b.

[0048] Further, such as Fig. 9 In this embodiment, a selection member 500 is provided on the connecting frame bottom plate 404, and the selection member 500 includes a pressing block 501 slidably connected to the connecting frame bottom plate 404, and the pressing block 501 slides along the length direction of the connecting frame bottom plate 404, and an intermediate block 502 is provided on the first rotating arc plate 405, and the height of the intermediate block 502 is consistent with the height of the surface block 409, and a toggle rod 503 is slidably connected to the intermediate block 502.

[0049] Further, such as Fig.10 , Fig.11A third inclined surface 504 is provided at the end of the toggle rod 503, a matching hole 505 matching with the toggle rod 503 is provided on the side wall of the pressing rod 409b, and a fourth inclined surface 506 matching with the third inclined surface 504 is provided in the matching hole 505. Two toggle rods 503 are provided, and a groove 507 is provided in the center of the middle block 502. The toggle rod 503 extends inwardly into the groove 507, and then an ear plate 508 is hinged at one end of the toggle rod 503 extending into the groove 507, and a contact plate 609 is rotatably connected in the groove 507. There are two contact plates 609, and they are symmetrically arranged. A side slide groove 700 is provided on the side wall of the contact plate 609, and the ear plate 508 is slidably connected to the side slide groove 700. The lower ends of the two contact plates 609 are hinged, and a torsion spring is provided at the hinge of the two contact plates 609.

[0050] Further, such as Figure 8 A pressing rod 701 is slidably connected to the pressing block 501, and a spring is provided between the pressing rod 701 and the pressing block 501. The spring always drives the pressing rod 701 to slide downward, and a conical block 702 is provided at the lower end of the pressing rod 701. After sliding, the conical block 702 contacts the two contact plates 609, and because a triangular space is formed between the two contact plates 609, the conical block 702 pushes the two contact plates 609 outward, so that the contact plates 609 rotate outward, thereby making the toggle rod 503 extend outward. When the toggle rod 503 is extended, the first rotating arc plate 405, the second rotating arc plate 406 and the third rotating arc plate 407 are connected to each other, and can rotate together.

[0051] Further, such as Figure 5 , Fig.12 A baffle 705 is provided at the upper end of the connecting frame bottom plate 404, and a first slide groove 703 is opened on the baffle 705. The first slide groove 703 is opened along the length direction of the connecting frame bottom plate 404, and then a plurality of second slide grooves 704 are opened on the first slide groove 703. In the present embodiment, three second slide grooves 704 are opened, corresponding to the first rotating arc plate 405, the second rotating arc plate 406 and the third rotating arc plate 407 respectively, and the pressing rod 701 at the lower end of the operating rod cooperates with the first slide groove 703 and the second slide groove 704.

[0052] Preferably, a telescopic rod is arranged between the pressing block 501 and the plug-in row 102. The connecting part between the telescopic rod and the pressing block 501 is hinged. The telescopic rod is an electrically controlled telescopic rod. The main function of the telescopic rod is to push the pressing block 501 to move forward and backward. The telescopic rod is arranged along the opening direction of the second slide groove 704, and the telescopic rod can move in the first slide groove 703 along with the pressing block 501.

[0053] Preferably, a coating layer is provided on the outer shell 104, and the coating layer is a rubber insulating layer.

[0054] It should be noted that the pressing block 501 is arranged above the baffle 705 and maintains a sliding connection with the upper surface of the baffle 705, and the size of the pressing block 501 is larger than the width of the first slide groove 703 and the second slide groove 704, so that the pressing block 501 can slide along the length direction of the first slide groove 703 and the second slide groove 704 (the length direction here is the opening direction of the first slide groove 703 and the second slide groove 704), and then the pressing block 501 can move to the position of any surface block 409, and the sliding of the pressing block 501 can drive the movement of the pressing rod 701. At this time, the operator can press the pressing rod 701 to drive the downward pressing of the lower pressing rod 409b, and when the pressing rod 701 is pressed down, , the lower end of the pressing rod 701 penetrates into the surface block 409 (because the upper end of the surface block 409 is opened), and the pressing block 501 is facing the second slide groove 704. The operator slides the pressing block 501 to move the pressing block 501 to a position opposite to the surface block 409, and then presses the pressing rod 701, so that the lower end of the pressing rod 701 can enter the surface block 409, and then the movement of the pressing rod 701 will drive the movement of the surface block 409. The above arrangement can realize the separate driving of the two surface blocks 409, thereby pushing the first connecting rod 301 or the second connecting rod 302 outward separately, and then realizing the separate control of the first power-collecting component 103a or the second power-collecting component 103b.

[0055] The function of the toggle rod 503 is to control the simultaneous downward pressing of the two downward pressing rods 409b when the pressing block 501 is located at the position of the middle block 502, thereby controlling the simultaneous pushing out of the first connecting rod 301 and the second connecting rod 302. Then, the movement of the pressing block 501 can drive the simultaneous movement of the first connecting rod 301 and the second connecting rod 302.

[0056] Operation process: When the operator is plugging, the operator, according to the selection, moves the pressing block 501 so that the pressing block 501 slides in the first slide groove 703. When it slides to the position of the first rotating arc plate 405, the operator presses the pressing block 501 downward. After the pressing rod 701 at the lower end of the pressing block 501 slides, the conical block 702 abuts against the contact plate 609 and pushes the two contact plates 609 outward. The two contact plates 609 are The first connecting rod 301 and the second connecting rod 302 are rotated from the state of being close to each other to the state of being far away from each other (that is, the state shown in the figure), and then the toggle rod 503 is extended outward. The movement of the toggle rod 503 pushes the fourth inclined surface 506 through the third inclined surface 504, so that the pressing rod 409b moves downward. When the pressing rod 409b slides downward, the second inclined surface 409a pushes the first inclined surface 408, so that the first connecting rod 301 and the second connecting rod 302 slide forward. The first connecting rod 301 and the second connecting rod 302 are respectively extended into the first power-collecting member 103a and the second power-collecting member 103b, so that the first connecting rod 301 and the second connecting rod 302, the first power-collecting member 103a, the surface block 409 and the second power-collecting member 103b are connected as one body, and then the above connection makes the first rotating arc plate 405, the second rotating arc plate 406 and the third rotating arc plate 407 connected to each other, so that at this time, it is only necessary to control the sliding of the surface block 409 to realize the common movement of the first power-collecting member 103a and the second power-collecting member 103b, thereby driving the first power-collecting member 103a and the second power-collecting member 103b to move from the standby state to the ready-to-plug state at the same time, and at this time, the sockets of the first power-collecting member 103a and the second power-collecting member 103b are opposite to each other, and then at this time, the operator can insert the plug into the first power-collecting member 103a and the second power-collecting member 103b to complete the plugging action;

[0057] Reference Fig.14When the operator inserts the plug into the first power-collecting member 103a, if the current detection module detects an abnormality (the plug is damaged or the plug is different), the pressing rod 701 is triggered to move horizontally (slide along the length direction of the first slide groove 703, and the sliding of the pressing rod 701 is realized by an electromagnet. A micro iron block is provided on the pressing rod 701, and a magnet that is energized and magnetized is provided on the second rotating arc plate 406 and the third rotating arc plate 407. The magnet is electrically connected to the circuit board of the signal feedback module through a wire, and then the magnet on the second rotating arc plate 406 or the third rotating arc plate 407 is energized (while the magnet is magnetized, the circuit board simultaneously receives the electrical signal on the signal feedback module, and determines that the signal is a signal that causes the magnet to be magnetized through the judgment module, and then the electrical signal can continue to be transmitted outward), thereby attracting the micro iron block on the pressing rod 701. shaped iron block, thereby realizing the sliding of the pressing rod 701), and then the pressing rod moves to the second slide groove 704 corresponding to the third rotating arc plate 407. At this time, the pressing rod 701 moves downward, so that the lower end of the pressing rod 701 pushes the lower pressing rod 409b, causing the lower pressing rod 409b to slide, and uses the inclined surface to push the second connecting rod 302 forward, thereby connecting the second power-collecting member 103b. At this time, the pressing rod 701 moves, driving the surface block 409 to move in the second slide groove 704, and when moving, it will drive the movement of the second power-collecting member 103b, so that the second power-collecting member 103b is no longer directly opposite to the first power-collecting member 103a. At this time, the corresponding state of the second power-collecting member 103b and the first power-collecting member 103a moves to a non-corresponding state. At this time, the plug cannot be plugged into the second power-collecting member 103b, so that connectivity cannot be achieved, and an error will be reported on the screen cabinet M.

When it slides to the first rotating arc plate position, the operator presses the pressing block downward. After the pressing rod at the lower end of the pressing block slides, the conical block abuts against the contact plate and pushes the two contact plates outward. Both contact plates rotate from a state originally close to each other to a state far away from each other, and then the toggle rod extends outward. The movement of the toggle rod pushes the fourth inclined plane through the third inclined plane, so that the lower pressing rod moves downward. When the lower pressing rod slides downward, the second inclined plane pushes the first inclined plane, so that the first connecting rod and the second connecting rod slide forward, thereby The first connecting rod and the second connecting rod extend into the first power-collecting member and the second power-collecting member respectively, so that the first connecting rod and the second connecting rod, the first power-collecting member, the surface block and the second power-collecting member are connected as one, and then the above connection makes the first rotating arc plate, the second rotating arc plate and the third rotating arc plate connected to each other, so that at this time, it is only necessary to control the sliding of the surface block to realize the common movement of the first power-collecting member and the second power-collecting member, thereby driving the first power-collecting member and the second power-collecting member to move from the standby state to the ready-to-plug state at the same time, at this time, the sockets of the first power-collecting member and the second power-collecting member are facing each other, and then at this time, the operator can insert the plug into the first power-collecting member and the second power-collecting member to complete the plugging action; When the operator inserts the plug into the first power-collecting component, if the current detection module detects an abnormality, the push rod is triggered to move horizontally, and then the push rod moves to the second slide groove corresponding to the third rotating arc plate. At this time, the push rod moves downward, so that the lower end of the push rod pushes the lower pressure rod, causing the lower pressure rod to slide, and uses the inclined surface to push the second connecting rod forward, thereby connecting the second power-collecting component. At this time, the push rod moves, driving the surface block to move in the second slide groove, and when moving, it drives the movement of the second power-collecting component, so that the second power-collecting component is no longer directly opposite to the first power-collecting component. At this time, the corresponding state of the second power-collecting component and the first power-collecting component moves to a non-corresponding state. At this time, the plug cannot be plugged into the second power-collecting component, so that connectivity cannot be achieved, and an error is reported on the screen cabinet M.
