Electric energy has the characteristics of zero emissions, high energy efficiency, and low operating and maintenance costs. The promotion and popularization of electric vehicles, electric motorcycles, etc. can effectively reduce the pressure of human development on the environment. When charging energy storage modules such as batteries, the charging seat is a necessary accessory. Electric vehicles, energy storage cabinets, electric motorcycles, and charging piles are all equipped with charging seats for connecting charging guns for charging. Since the charging gun is directly connected to the charging seat internally, and the charging connector is always in a charged state, it is easy to cause safety problems with the charging seat.

[0003] After searching, the Chinese invention patent with patent application number CN202120577285.0 discloses an electric two-wheeled vehicle anti-electric shock charging socket, which has a controllable on-off circuit, the output end of the controllable on-off circuit is connected to the power input end of the battery inside the electric vehicle; the input end of the controllable on-off circuit is connected to the power output end of the external charger of the electric vehicle; the controllable on-off circuit realizes the connection or disconnection of the circuit itself through the control signal of the external charger. This invention sets a controllable on-off circuit between the charging terminal of the charging socket and the battery. Under the control of the control signal, the controllable on-off circuit in the charging socket can connect or disconnect the battery and the charging port, which can avoid the risk of electric shock to the user due to the live plug, and can also avoid heating of the wiring harness due to short circuit, and even fire and other accidents.

[0021] The three-safety door anti-electric shock design effectively prevents electric shock through the following mechanisms:

[0022] 1. Physical barriers and isolation:

[0023] Anti-electric shock protective cover: First of all, an anti-electric shock protective cover is configured on the outside of the charging column. This layer of protective cover itself is a physical barrier that can initially prevent external objects from directly contacting the internal live parts.

[0024] Upper right safety door, upper left safety door and lower safety door: On the anti-electric shock protective cover, the upper right safety door, upper left safety door and lower safety door are symmetrically installed. These three doors are in a vertical state under normal conditions, tightly closing the inner side of the charging stand body to prevent direct insertion of external objects.

[0025] 2. Dynamic response mechanism:

[0026] Charging gun triggering: When the charging gun is inserted, the hole wall of the protection hole will first contact the ends of the upper right safety door, the upper left safety door and the lower safety door. This contact will push the safety door to rotate from a vertical state to a horizontal state, thereby providing a channel for the charging cell on the charging gun to be smoothly inserted into the charging seat body.

[0027] Spring reset: After the charging gun is pulled out, the upper right safety door, upper left safety door and lower safety door will automatically rotate from horizontal to vertical under the action of the spring, and re-close the inner side of the charging station body. This dynamic response mechanism ensures that the safety door can maintain an effective protection state when the charging gun is inserted and pulled out.

[0028] 3. Safety door design and materials:

[0029] Safety door movable through hole: The safety door movable through hole designed on the anti-electric shock protective cover allows the toggle plates of the upper right safety door, the upper left safety door and the lower safety door to extend flexibly while maintaining the overall structural strength.

[0030] Material selection: The materials of safety doors and anti-electric shock protective covers are usually selected with good insulation properties and mechanical strength, such as plastic or rubber, to ensure that they can effectively isolate current and withstand certain physical impacts.

[0031] 4. Comprehensive protection effect:

[0032] Prevent accidental touch: By adding an anti-electric shock protective cover and a safety door, this design effectively prevents external objects, including the human body, from directly contacting the internal live parts, thereby greatly reducing the risk of electric shock.

[0033] Improved safety: Even if the charging station is accidentally touched, the safety door and the insulating properties of the material can effectively prevent the current from passing through the human body, ensuring the safety of the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] like Figures 3 to 5The charging seat body 1 includes an embedded part 8, a mounting plate 9 and an outer cover part 10. The mounting plate 9 is integrally connected with the embedded part 8 and the outer cover part 10 respectively. The outer cover part 10 is arranged around the periphery of the anti-electric shock protective cover 3. The upper right safety door 4, the upper left safety door 41 and the lower safety door 5 all include a toggle plate 11, three rotating columns 12 and an inner baffle plate 13. The three rotating columns 12 are integrated with the toggle plate 11 and the inner baffle plate 13. The upper part of the anti-electric shock protective cover 3 is provided with a safety door installation groove 15 connected with the safety door movable through hole 6. The outer end of the toggle plate 11 extends to the outside of the safety door movable through hole 6. The three sides of the safety door installation groove 15 are provided with rotating column plug holes 31. The three ends of the rotating column 12 are movably inserted into the interior of the rotating column plug hole 31. When the toggle plate 11 rotates into the interior of the safety door movable through hole 6, the inner baffle plate 13 rotates into the interior of the safety door installation groove 15.

[0055] like Figure 7 The spring 7 includes a U-shaped blocking rod 71, and the three ends of the spring 7 are integrally formed with spring coils 72. The ends of the spring coils 72 each extend a straight blocking rod 73. The three spring coils 72 are respectively sleeved on the outside of the three rotating columns 12. The U-shaped blocking rod 71 is located on the inner side of the toggle plate 11, and the straight blocking rod 73 is against the inner wall of the safety door installation groove 15. Through the elastic force of the spring 7, the upper right safety door 4, the upper left safety door 41 and the lower safety door 5 are in a vertical state in the initial state.

[0056] like Figure 1 and Figure 2 As shown, a limiting sleeve 102 is provided inside the outer cover 10, and the number of the limiting sleeves 102 can be set according to actual needs. The plug 1601 is provided with limiting holes 162 corresponding to the limiting sleeves 102 one by one, and a limiting rod 1621 is provided inside the limiting hole 162, which improves the stability between the charging gun 16 and the charging seat body 1.

[0057] like Figure 1 and Figure 2 As shown, an alignment platform 101 is provided on the top of the outer cover 10, and an alignment boss 163 is provided on the charging gun 16.

[0059] like Figure 8As shown, in order to facilitate the installation of the charging stand body 1 on the vehicle body, mounting holes 91 are provided at the four corners of the mounting plate 9, and a connecting sleeve 81 is provided on the embedded part 8. The mounting holes 91 and the connecting sleeve 81 facilitate the installation of the charging stand body 1 on the vehicle body.

[0060] Structural principle:

[0061] like Figures 9 to 11 As shown, the alignment boss 163 on the charging gun 16 is aligned with the alignment platform 101, and the plug 1601 is inserted into the interior of the outer cover 10. When the plug 1601 is inserted into the interior of the outer cover 10, the protective hole 161 is sleeved on the outside of the anti-electric shock protection cover 3, and the hole wall of the protective hole 161 first contacts the upper right safety door 4, the upper left safety door 41 and the lower safety door 5. The toggle plate 11, thereby pushing the upper right safety door 4, the upper left safety door 41 and the lower safety door 5 to rotate from a vertical state to a horizontal state, thereby facilitating charging. The charging cell 17 on the gun 16 is inserted into the anti-electric shock protection cover 3 and connected to the charging column 2. At this time, the toggle plate 11 is in a horizontal state inside the movable through hole 6 of the safety door, and the inner baffle 13 rotates into the interior of the safety door installation groove 15 and is in a horizontal state; when the charging gun 16 is pulled out, the upper right safety door 4, the upper left safety door 41 and the lower safety door 5 are rotated from a horizontal state to a vertical state under the action of the spring 7, thereby blocking the inner side of the charging seat body 1 to prevent other objects from being inserted into and touching the internal charging column 2.

[0062] The three-safety door anti-electric shock design effectively prevents electric shock through the following mechanisms:

[0063] 1. Physical barriers and isolation:

[0064] Anti-electric shock protective cover 3: First, an anti-electric shock protective cover 3 is arranged on the outside of the charging column 2. This layer of protective cover itself is a physical barrier, which can initially prevent external objects from directly contacting the internal live parts.

[0065] The upper right safety door 4, the upper left safety door 41 and the lower safety door 5: The upper right safety door 4, the upper left safety door 41 and the lower safety door 5 are symmetrically installed on the anti-electric shock protection cover 3. These three doors are in a vertical state under normal conditions, tightly closing the inner side of the charging stand body 1 to prevent direct insertion of external objects.

[0066] 2. Dynamic response mechanism:

[0067] Charging gun triggering: When the charging gun 16 is inserted, the hole wall of the protection hole 161 will first contact the ends of the upper right safety door 4, the upper left safety door 41 and the lower safety door 5. This contact will push the safety door to rotate from a vertical state to a horizontal state, thereby providing a channel for the charging cell 17 on the charging gun 16 to be smoothly inserted into the charging seat body 1.

[0068] Spring 7 reset: After the charging gun is pulled out, the upper right safety door 4, the upper left safety door 41 and the lower safety door 5 will automatically rotate from the horizontal state to the vertical state under the action of the spring 7, and re-close the inner side of the charging seat body 1. This dynamic response mechanism ensures that the safety door can maintain an effective protection state when the charging gun 16 is inserted and pulled out.

[0069] 3. Safety door design and materials:

[0070] Safety door movable through hole 6: The safety door movable through hole 6 designed on the anti-electric shock protection cover 3 allows the upper right safety door 4, the upper left safety door 41 and the toggle plate 11 of the lower safety door 5 to be flexibly extended while maintaining the overall structural strength.

[0071] Material selection: The material of the safety door and the anti-electric shock protective cover 3 is usually selected to have good insulation performance and mechanical strength, such as plastic or rubber, to ensure that it can effectively isolate the current and withstand certain physical impacts.

[0072] 4. Comprehensive protection effect:

[0073] Prevent accidental touch: By adding the anti-electric shock protective cover 3 and the safety door, the design effectively prevents external objects including the human body from directly contacting the internal live parts, thereby greatly reducing the risk of electric shock.

[0074] Improved safety: Even if the charging station is accidentally touched, the safety door and the insulating properties of the material can effectively prevent the current from passing through the human body, ensuring the safety of the user.

[0075] In summary, the three-safety-door anti-electric shock design effectively prevents electric shock accidents through multiple mechanisms such as physical barriers and isolation, dynamic response mechanism, safety door design and materials, and comprehensive protection effects.

[0076] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
