The two conductive sheets 79 form a herringbone structure. The third vertical section 81 is connected to a side contact 84. The two side contacts 84 are initially abutted against each other. At this time, the indicator light is on, proving that the moving contact 45 is not in contact with the static contact 49. When the electromagnetic coil 6 is energized, the arc section 63 abuts against the static contact 49, and the insertion head 75 is inserted between the conductive sheets 79 to separate the two side contacts 84, and the indicator light goes out, realizing the display of the connection status between the moving contact 45 and the static contact 49, so as to better judge the source of the line problem.

[0060] like Fig. 22 and Fig.23 As shown, as an optimization of the embodiment, considering that the upper contact 48 is now in contact with the lower contact 54 to realize circuit connection, there is no auxiliary contact structure, and three moving auxiliary contacts 86 are fixed to the top surface of the support seat 36 through the second bridge seat 85. The moving auxiliary contact 86 is V-shaped, and the bottom surface of the moving auxiliary contact 86 is connected to the upper auxiliary contact 87; three rectangular grooves 88 are opened on the arc extinguishing cover 20, and static auxiliary contacts 89 are installed in the rectangular grooves 88. The top surface of the static auxiliary contact 89 is connected to the lower auxiliary contact 90, and the upper auxiliary contact 87 is opposite to the lower auxiliary contact 90, and the distance from the upper auxiliary contact 87 to the lower auxiliary contact 90 is the same as the distance from the upper contact 48 to the lower contact 54. When the moving contact 45 is connected to the static contact 49, that is, the moving auxiliary contact 86 is connected to the static auxiliary contact 89, to assist in conducting the circuit.

[0061] like Fig.24As shown, as an optimization of the embodiment, considering that the upper contact 48 will hit the lower contact 54 when it descends, a wedge-shaped surface 91 is opened at the lower edge of the upper contact 48, and a buffer spring 92 is fixed to the static contact 49 by screws. The number of the buffer springs 92 is 2, and the two buffer springs 92 are symmetrically arranged. The buffer spring 92 is composed of a third slope section 93, a fourth vertical section 94, a fourth slope section 95, a fifth vertical section 96, and a fourth flat section 97 arranged from top to bottom. The third slope section 93 is adapted to the wedge-shaped surface 91. At this time, the upper contact 48 is against the lower contact 54, and the fourth flat section 97 is connected to the static contact 49. By setting the buffer spring 92, the impact between the upper contact 48 and the lower contact 54 can be reduced.

[0062] like Figure 25~Figure 27 As shown, as an optimization of the embodiment, considering that the armature 15 will impact the iron core 5 when it descends, the two vertical sections of the armature 15 are provided with a sink 98, a guide rail 99 is connected in the sink 98, and a T-shaped guide groove 100 is provided on the guide rail 99, a first slider 101 is slidably connected to the T-shaped guide groove 100, a first rack 102 is connected to the first slider 101, the first rack 102 is L-shaped, and the vertical section of the first rack 102 has a tooth groove; a second slider 103 is slidably connected to the T-shaped guide groove 100, a second rack 104 is slidably connected to the second slider 103, the second rack 104 is L-shaped, and the vertical section of the second rack 104 has a tooth groove; the horizontal section of the first rack 102 is connected to the horizontal section of the second rack 104 A fifth spring 105 is connected; a rotating shaft 106 is rotatably connected to the guide rail 99, and a gear 107 is connected to the rotating shaft 106.

The buffer seat 109 initially protrudes below the armature 15, and a notch groove 110 for accommodating the buffer seat 109 is provided on the guide rail 99. When the armature 15 abuts against the iron core 5, the buffer seat 109 shrinks into the notch groove 110. During the upward movement of the first rack 102, the impact force of the armature 15 on the iron core 5 is absorbed by the transmission of the gear 107 and the rack and the shock absorption of the fifth spring 105.

[0063] Furthermore, considering that many charging stations in the market do not monitor the charging piles 113 and the parking spaces 111 where the charging piles 113 are located, the parking spaces 111 with charging piles 113 are often occupied by non-new energy vehicles, making it impossible for electric vehicles to charge. This has certain resistance to the promotion of new energy vehicles. At the same time, the long-term occupation of the charging parking spaces 111 by fuel vehicles also reduces the income of the charging piles 113, which is not conducive to the allocation of public resources. Fig.28 and Fig.29As shown, a platform-free docking anti-occupancy and anti-tampering charging system using a charging switch control component is proposed, including a background control terminal and a plurality of charging stations, each of which includes a plurality of parking spaces 111, and each parking space 111 is equipped with a parking flat plate lock 112, a charging pile 113, an anti-collision guardrail 114 and a side guardrail 115; the background control terminal includes a remote charging control box and an intelligent terminal 116, and the remote charging control box includes an air switch 117, an emergency switch 118, a low-power WIFI smart socket 119, a charging switch control component, and a high-power three The remote charging control box is connected to the smart terminal 116 through the WIFI router 121, and is connected to the three-phase power grid through the air switch 117; the charging switch control component is respectively connected to the air switch 117 and the high-power three-core socket 120, and is connected to the WIFI router 121 through the low-power WIFI smart socket 119; the high-power three-core socket 120 is led out from the charging switch control component and is arranged outside the remote charging control box; the emergency switch 118 is connected in series to the low-power WIFI smart socket 119; the WIFI router 121 is connected to the third-party public cloud 123 through the Internet 122, and is connected to the smart terminal 116 through the Internet 122 and the public communication base station 124; the overall system process is as follows: when the charging vehicle enters the parking space body 111 normally, the vehicle detector checks that the car is parked, the charging gun BMS line is connected, and after scanning the code to start charging, the BMS signal line has 12V electricity. After charging is successful, the corresponding BMS time relay switch stops timing or returns to zero. When there is a car occupying the space next to it but not charging, the BMS charging switch control group will automatically disconnect after two minutes of occupying the space to prevent charging from usurping the space. At this time, the parking space tablet lock 112 will be activated 15 minutes after the vehicle occupying the space next to it, and the parking space occupation timer will begin. The vehicle can only lock the car and leave the vehicle after scanning the code and paying the parking space fee. After the charging vehicle has parked for free for two hours or the charging vehicle has not left the parking space for 15 minutes after being fully charged, the parking space tablet lock 112 will rise and the parking space occupation fee will begin to be counted. After the parking space occupation fee is paid by scanning the code, the parking space tablet lock 112 will be locked. The advantage of this system is that it can effectively control the occupation of the charging pile 113 and the parking space body 111, prevent green-plate and blue-plate vehicles that are not charging from occupying the space, effectively solve the problem of charging guns usurping the space for charging, and green-plate and blue-plate vehicles that are not charging can be charged parking space fees.
