[0040] An embodiment of one aspect of the present invention, in combination with Figure 1As shown, a charging unlocking mechanism is provided, including a shell 1, an unlocking button 2, which is arranged on the shell 1; an unlocking component 3, which is arranged inside the shell 1, including an unlocking rod 31 and a blocking block 32, when the unlocking button 2 is pressed, the blocking block 32 releases the unlocking rod 31, and the unlocking rod 31 can rotate freely; an electromagnetic lock 41 component 4, including an electromagnetic lock 41 and a pressing component 42, the pressing component 42 is installed on the shell 1, when the electromagnetic lock 41 is energized, the electromagnetic lock 41 pushes the pressing component 42 downward; the pressing component 42 drives the unlocking rod 31 to rotate, and the metal block 33 at the end of the unlocking rod 31 contacts the metal patch 12 on the shell 1, so that the upper structure in contact with the metal patch 12 is energized. By pressing the unlock button 2, the blocking block 32 slides to release the unlock rod 31. At the same time, the electromagnetic lock 41 is energized to apply a feeding force, pushing the pressing component 42 downward to drive the unlock rod 31 to rotate. Unlocking is achieved under the joint action of the unlock button 2 and the electromagnetic lock 41 component 4, thereby improving the safety performance of charging unlocking.

[0041] In an optional embodiment, if Figure 2 and Figure 5 As shown, the housing 1 is composed of a plurality of connected side panels 14. A first groove 11 matching the size of the blocking block 32 is provided on the upper and lower side panels inside the housing 1. The blocking block 32 can slide along the first groove 11. For example, when the unlock button 2 is pressed, the unlock button 2 can push the blocking block 32 to slide within the first groove 11. Optionally, a limiting mechanism is further provided outside the first groove 11 to limit the sliding of the blocking block 32 and prevent it from sliding out of the first groove 11.

[0042] Understandably, the reference Figure 2 、 Figure 3 and Figure 4 As shown, in order to enable the block 32 to lock the unlocking rod 31 and prevent the unlocking rod 31 from rotating when the unlocking button 2 is not pressed, a block portion 321 is provided on the block 32. The block portion 321 is located on one side of the block 32, and when the unlocking button 2 is not pressed, as shown in FIG. Figure 3 As shown, the blocking portion 321 abuts against the unlocking lever 31 to prevent the unlocking lever 31 from rotating. After the unlocking button 2 is pressed, as shown in FIG. Figure 4 As shown, the unlocking button 2 can push the blocking block 32 to slide in the first groove 11. At this time, the unlocking rod 31 is separated from the blocking portion 321, and the unlocking rod 31 can rotate.

[0043] In an optional embodiment, if Figure 2As shown, in order to enable electrical connection after the unlocking lever 31 is rotated, a metal block 33 is connected to the unlocking lever 31, and a metal patch 12 is provided at a corresponding position on the housing 1. When the unlocking lever 31 is rotated, the metal block 33 at the end of the unlocking lever 31 can abut the metal patch 12, thereby achieving electrical conduction. Optionally, the metal block 33 can also be a metal rod, one end of which is connected to the end of the unlocking lever 31. When the unlocking lever 31 rotates, the metal rod rotates with the unlocking lever 31, and the other end can be in contact with the metal patch 12 to achieve electrical conduction.

[0044] It is understandable that, combined with Figure 2 As shown, a fixed support 13 is provided inside the housing 1, and the fixed support 13 is rotatably connected to the unlocking rod 31, so that the unlocking rod 31 can rotate around the fixed support 13 inside the housing 1. Optionally, a bearing can also be installed on the fixed support 13 to facilitate the rotation of the unlocking rod 31.

[0045] Furthermore, the housing 1 is composed of an upper top plate, a lower bottom plate, a left and right side plate group, and a front and rear side plate group. The upper top plate is connected to the left and right side plate group and the front and rear side plate group, and is connected to the unlocking button 2 and the electromagnetic lock assembly 4; the lower bottom plate is connected to the left and right side plate group 14 and the front and rear side plate group 14, and the fixing support 13 is set on the lower bottom plate. The fixing support 13 is connected to the lower bottom plate to fix the unlocking rod 31; through holes 141 are set on the front and rear side plate groups for wires to pass through and realize electrical connection with the metal block 33. Figure 1 、 Figure 2 and Figure 5 As shown, the phase line enters from the through hole 141 on the left, and the live line enters from the through hole 141 on the right, and is connected from the wire groove at the bottom of the shell 1 to the wiring hole 331 at the lower part of the unlocking rod 31 to realize the power supply of the end of the unlocking rod 31.

[0046] In an optional embodiment, combined with Figure 2 As shown, the pressing assembly 42 includes a pressing block 421 and a pressing rod 422. The pressing block 421 is arranged on the shell 1 and can slide along the upper top surface of the shell 1. The pressing rod 422 is fixedly connected to the bottom of the pressing block 421. The pressing rod 422 passes through the upper top plate of the shell 1 and is slidably connected to the unlocking rod 31. When the pressing block 421 is pressed down, the pressing rod 422 is pressed down to drive the unlocking rod 31 to rotate around the fixed support 13 to complete the unlocking.

[0047] Optional, combined Figure 2 As shown, the lower pressing block 421 can be a wedge-shaped structure, and its side close to the electromagnetic lock 41 is an inclined surface, which can receive the horizontal pushing force from the electromagnetic lock 41 and slide along the upper top plate of the shell 1; optionally, the lower pressing block 421 and the lower pressing rod 422 can be made separately and welded together; optionally, the lower pressing block 421 and the lower pressing rod 422 can also be made in one piece, and this application does not make specific restrictions on this.

[0048] In an optional embodiment, combined with Figure 4 As shown, in order to enable the unlock button 2 to push the blocking block 32 to slide after being pressed, a wedge block 21 is provided below the unlock button 2, and the inclined surface of the wedge block 21 contacts the blocking block 32. In this way, when the unlock button 2 is pressed, the wedge block 21 can push the blocking block 32 to slide along the first groove 11, releasing the unlock rod 31.

[0049] It can be understood that when the charging unlocking structure is in the initial state, pressing the unlocking button 2 can only achieve the unlocking effect of the unlocking rod 31, and the pressing component 42 can only partially rotate the unlocking rod 31, and cannot make the metal block 33 connected to the end of the unlocking rod 31 connected to the metal patch 12 on the upper top plate of the shell 1 to achieve conductivity. The unlocking button 2 and the electromagnetic lock component 4 cannot control the power connection independently. The power connection can only be achieved when the unlocking button 2 is pressed and the electromagnetic lock component 4 works at the same time, ensuring the safety of the power connection.

[0050] In an optional embodiment, combined with Figure 2 and Figure 5 As shown, a second groove 311 is provided at one end of the unlocking rod 31 close to the pressing assembly 42. When the pressing assembly 42 is pressed down, the pressing rod 422 can slide along the groove of the second groove 311, driving the rotation of the unlocking rod 31, while preventing the pressing rod 422 from detaching from the unlocking rod 31 and affecting the rotation of the unlocking rod 31.

[0051] Optional, combined Figure 1 As shown, a cover body 15 is provided on the upper top plate of the housing 1 , and a lower pressing block 421 is provided inside the cover body 15 and slides inside the cover body 15 to prevent the lower pressing block 421 from being separated from the housing 1 .

[0052] Further, combined Figure 6As shown, the charging unlocking mechanism also includes a shelf 5, an electromagnetic lock 41 installed within the shelf 5. One end of the shelf 5 is open, and the electromagnetic lock 41 extends from the opening. When the electromagnetic lock 41 is in operation, it can push the lower pressure block 421 to slide along the upper plate of the housing 1, driving the rotation of the unlocking lever 31. At the same time, a copper sheet is installed at the bottom of the shelf 5 corresponding to the metal patch 12. When the unlocking lever 31 rotates, the metal rod at the end of the unlocking lever 31 can connect with the metal patch 12 at the top of the housing 1 and the copper sheet at the bottom of the shelf 5, making the shelf 5 conductive. In actual work, it is only necessary to place the shelf 5 equipped with the electromagnetic lock 41 on the upper top plate of the shell 1. The gravity of the shelf 5 and the electromagnetic lock 41 can be used to automatically press the unlocking button 2. The blocking block 32 slides horizontally to release the unlocking rod 31. The electromagnetic lock 41 feeds horizontally and applies force to make the lower pressure rod 422 push the unlocking rod 31 downward to rotate. At this time, the metal block 33 connected to the unlocking rod 31 touches the metal patch 12 of the upper top rod. At the same time, the metal patch 12 is connected to the copper sheet at the bottom of the shelf 5, completing the power connection of the shelf 5.

[0053] An embodiment of the present invention provides a charging unlocking mechanism, including a shell 1, an unlocking button 2, which is arranged on the shell 1; an unlocking component 3, which is arranged inside the shell 1, including an unlocking rod 31 and a blocking block 32, when the unlocking button 2 is pressed, the blocking block 32 releases the unlocking rod 31, and the unlocking rod 31 can rotate freely; an electromagnetic lock 41 component 4, including an electromagnetic lock 41 and a pressing component 42, the pressing component 42 is installed on the shell 1, when the electromagnetic lock 41 is energized, the electromagnetic lock 41 pushes the pressing component 42 downward; the pressing component 42 drives the unlocking rod 31 to rotate, and the metal block 33 at the end of the unlocking rod 31 contacts the metal patch 12 on the shell 1, so that the upper structure in contact with the metal patch 12 is energized. By pressing the unlock button 2, the blocking block 32 slides to release the unlock rod 31. At the same time, the electromagnetic lock 41 is energized to apply a feeding force, pushing the pressing component 42 downward to drive the unlock rod 31 to rotate. Unlocking is achieved under the joint action of the unlock button 2 and the electromagnetic lock 41 component 4, thereby improving the safety performance of charging unlocking.
