[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of the electric vehicle charging pile anti-blocking alarm provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the protection assembly shown; Figure 3 for Figure 2 The schematic diagram of the structural connection between the protective plate and the movable plate shown; Figure 4 for Figure 1 The electric vehicle charging pile anti-blocking alarm comprises a charging pile body 1, and the front surface of the charging pile body 1 is respectively provided with a first warning light 2 and a second warning light 3;

[0023] The protective component 4 is arranged on the front surface of the charging pile body 1. The protective component 4 includes a protective plate 41, a movable plate 42, a sealing plate 43 and a slide groove 44. The front surface of the charging pile body 1 is provided with a protective plate 41, the top of the protective plate 41 is provided with a movable plate 42, the inner circle of the protective plate 41 is fixedly connected with the sealing plate 43, and the interior of the charging pile body 1 is provided with a slide groove 44.

[0024] In the specific implementation process, Figure 2 and Figure 3 As shown, a fixing bar 5 is fixedly connected to the top of the moving plate 42, and the number of the fixing bars 5 is set to two.

[0025] A groove 6 is formed inside the protective plate 41 , and a fixing rod 7 is fixedly connected to the bottom of the inner cavity of the slide groove 44 .

[0026] A first spring 10 is welded to one side of the inner wall of the groove 6 , and a bottom block 12 is welded to one end of the first spring 10 .

[0027] The top of the bottom block 12 is fixedly connected to the bottom of the moving plate 42 , the rear surface of the protective plate 41 is fixedly connected with a connecting strip 11 , and the outer side of the connecting strip 11 is slidably connected to the inner wall of the sliding groove 44 .

[0028] It should be noted that: when the device is in normal use, under the action of the protective plate 41, the movable plate 42 and the sealing plate 43, a closed space can be formed on the outside of the charging seat body 9, so that the charging seat body 9 can be fully protected to prevent external rainwater and debris from entering the interior of the charging seat body 9, causing the charging seat body 9 to be blocked. At the same time, when it is necessary to charge the electric vehicle through the charging seat body 9, the movable plate 42 is first pushed to move through the fixed bar 5, and then the movable plate 42 can drive the bottom block 12 to move, so that the bottom block 12 can compress the first spring 10. After the bottom block 12 moves to the specified position, the connecting bar 11 is slid, and the protective plate 41 can be driven to move under the action of the connecting bar 11, so that the connecting bar 11 slides on the outside of the fixed rod 7. After the protective plate 41 moves to the specified position, the user can charge the electric vehicle through the charging seat body 9.

[0029] refer to Figure 4 As shown, a charging base body 9 is provided on the front surface of the charging pile body 1 , and a shell 13 is provided on the front surface of the charging base body 9 .

[0030] The top and bottom of the charging seat body 9 are fixedly connected with a positioning plate 8, a pressure sensor 16 and a voltage detection sensor 17 are respectively arranged on one side of the inner wall of the charging seat body 9, and a PLC controller 18 is arranged at the bottom of the inner cavity of the charging seat body 9.

[0031] A second spring 15 is disposed on the front surface of the pressure sensor 16 , and a push plate 14 is welded to the front surface of the second spring 15 .

[0032] It should be noted that: when the electric vehicle is charging, the charger plug enters the interior of the charging seat body 9, and the entry can push the push plate 14. When the push plate 14 moves, the second spring 15 is compressed, so that the pressure sensor 16 receives a signal, so that the first warning light 2 works normally. When the charging seat body 9 is blocked, the pressure sensor 16 continues to receive signals. At the same time, under the action of the second spring 15, the pressure fluctuates over a large range, and the first warning light 2 flashes to remind the user. At the same time, the voltage detection sensor 17 can detect the voltage of the charging seat body 9. When the voltage of the charging seat body 9 fluctuates greatly, or when the charging seat body 9 is damaged, a signal is sent to the second warning light 3, so that the second warning light 3 starts to work to remind the user.

[0033] The working principle of the electric vehicle charging pile anti-blocking alarm provided by the utility model is as follows:

[0034] When the user needs to use the device to charge the electric vehicle, the user first pushes the movable plate 42 to move through the fixed bar 5, and then the movable plate 42 can drive the bottom block 12 to compress the first spring 10. After the movable plate 42 moves to the specified position, the connecting bar 11 is slid so that the connecting bar 11 slides on the outside of the fixed rod 7, and then the connecting bar 11 can drive the protective plate 41 to move during movement, and then the protective plate 41 moves to the specified position, so that the user can charge the electric vehicle. After the charger plug enters the interior of the charging seat body 9, it will push the push plate 14 to move, so that the pressure sensor 16 receives a signal, thereby detecting the pressure it is subjected to. When the pressure fluctuates continuously within a certain range, the first warning light 2 can flash to remind the staff and users. At the same time, the voltage detection sensor 17 can detect the voltage of the charging seat body 9, and then the signal is transmitted through the second warning light 3 to further warn the normal use of the charging seat body 9.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
