Then, the gas in the gas fire extinguisher will be transported to the inside of the charging box through the air pipe and the gas transmission guide pipe, and the fire inside the charging box will be extinguished by the gas. At the same time, the rupture of the thermistor block causes the gas transmission guide pipe to be controlled by the force generated by the deformation of the connecting spring, thereby blocking the through hole and the drain pipe of the gas transmission guide pipe.

[0018] 2. The detachment module of the present invention is led out from the charging box to the outside of the charging box, and the axis of the detachment module is inclined in the direction away from the placement box. The end of the storage tube connected to the charging gun is closer to the ground. When a fire occurs in the charging box, the airbag ball is heated to expand the air in the airbag ball and the airbag strip, and the airbag strip surrounding the airbag groove will occupy more space, thereby exerting pressure on all the locking blocks, thereby pushing the locking spring to contract. When the locking spring contracts to a certain position, the locking block will be pushed out of the airbag groove, and the connection ring and the storage tube will lose the nesting of the locking block, resulting in the storage tube and the connecting ring being detached, and the storage tube will drive the charging gun to detach from the charging box, which can effectively prevent the increase of fire points and prevent the fire from spreading outside the charging box, thereby avoiding potential risks.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to Figure 1-Figure 6 The present invention provides a new energy vehicle wall-mounted charging pile structure, and the specific implementation scheme is as follows:

[0028] like Figure 1-Figure 4 As shown, a wall-mounted charging pile structure for new energy vehicles includes a charging box 1, a fire protection module 2 is arranged above the charging box 1, and a charging gun 4 is connected to the bottom of the charging box 1 through a wire 5;

[0029] The fire module 2 includes a placement box 21, a gas fire extinguisher 211, an air pipe 22, a gas delivery guide pipe 23, a thermal block 24, a hooking rope 25, an insulating sheet 251, a hooking spring 252, a connecting spring 26, a first sealing ring 221, a second sealing ring 231, a thermal ball 234 and an alarm 252. The placement box 21 is arranged above the charging box 1, and the placement box 21 is arranged in the placement box 21. One end of the air pipe 22 is connected to the side of the gas fire extinguisher 211, and the other end of the air pipe 22 passes through the side of the charging box 1 and is arranged in the charging box 1. The other end of the air pipe 22 is sleeved by the gas delivery guide pipe 23, and the air pipe 22 is sleeved with a thermal ball at the end away from the gas fire extinguisher 211. 234, the gas delivery guide tube 23 is provided with an arc-shaped blocking through hole 233 at one end connected to the thermosensitive ball 234, and the end of the gas delivery guide tube 23 connected to the blocking through hole 233 is in conformity with the shape of the thermosensitive ball 234, and the gas delivery guide tube 23 is connected with one end of a hooking rope 25 at one end close to the thermosensitive ball 234, and the other end of the hooking rope 25 passes through the top of the charging box 1 and the placement box 21 and is led out to the top of the placement box 21 and connected to the alarm 252, and an insulating sheet 251 is provided between the hooking rope 25 and the alarm 252, and a hooking spring 252 is sleeved on the outside of the hooking rope 25, and the hooking spring 252 is located inside the charging box 1, and the hooking spring 252 is connected to the top of the charging box 1;

[0030] A first sealing ring 221 is provided between the thermal ball 234 and the air pipe 22. The first sealing ring 221 fits the connection between the air pipe 22 and the thermal ball 234. The first sealing ring 221 is connected to the air pipe 22 and the thermal ball 234 to prevent the gas from passing through the gap between the air pipe 22 and the thermal ball 234 and entering the charging box 1. The gas delivery guide pipe 23 is provided with a second sealing ring 231 at one end away from the thermal ball 234. The second sealing ring 231 is sleeved on the outside of the air pipe 22. The second sealing ring 231 is located between the outer side of the air pipe 22 and the air delivery guide pipe 23 to seal the air pipe 22 and the air delivery guide pipe 23.

[0031] A connecting rail 27 is provided on the outer side of the gas delivery guide tube 23 away from the placement box 21, and one end of a connecting spring 26 is provided on the side of the charging box 1 close to the second sealing ring 231. The other end of the connecting spring 26 is connected to a sliding sheet, which is slidably connected to the connecting rail 27. When the sliding sheet slides, the connecting spring 26 slides in the sliding rail. When the gas delivery guide tube 23 is connected to the charging box 1 through the thermal block 24, the connecting spring 26 can slide in the connecting rail 27. One end of the connecting spring 26 will slide in the connecting rail 27 to the point with the smallest bending degree, thereby reducing the bending degree of the connecting spring 26 to a certain extent, and reducing the plastic deformation of the connecting spring 26.

[0032] One end of a discharge pipe 232 is respectively arranged in the gas delivery guide pipe 23 and the air pipe 22, and one end of a plurality of discharge pipes 232 is arranged on the contact surface between the gas delivery guide pipe 23 and the thermistor ball 234. The other end of the discharge pipe 232 passes through the gas delivery guide pipe 23 and is led to the air pipe 22 near the second sealing ring 231. A plurality of small holes are arranged between the discharge pipe 232 and the outer side surface of the gas delivery guide pipe 23. The small holes are used for gas to be led out from the contact surface between the gas delivery guide pipe 23 and the thermistor ball 234 to the discharge pipe 232 when the thermistor ball 234 is broken, and then led to the charging box 1 through the small holes. A thermistor block 24 is arranged between the outer side surface of the gas delivery guide pipe 23 and the top of the charging box 1, and is connected to the charging box 1 through the thermistor block 24. It is determined that when a fire occurs, the thermistor block 24 is heated, which causes the liquid inside the thermistor block 24 to expand due to heat, causing the plastic outside the liquid to rupture, thereby causing the thermistor block 24 to rupture as a whole. The thermistor block 24 ruptures as a whole, causing the connecting spring 26 to deform, thereby using the deformation force of the connecting spring 26 to drive the air pipe 22 and the gas delivery guide pipe 23 to move toward the bottom of the charging box 1 in the charging box 1, and then the liquid in the thermistor ball 234 expands due to heat, causing the plastic outside the liquid to rupture, and then the thermistor ball 234 ruptures. At this time, the air pipe 22 can transport the gas with fire extinguishing function in the gas fire extinguisher 211 to pass through the blocking through hole 233 and the small hole to the inside of the charging box 1, thereby playing a role in alleviating the fire and extinguishing the initial fire;

[0033] At the same time, when the air pipe 22 and the air supply guide pipe 23 move toward the bottom of the charging box 1, the end of the air supply guide pipe 23 connected to the hook rope 25 will be subjected to the force generated by the air pipe 22 and the air supply guide pipe 23 moving toward the bottom of the charging box 1, and then the other end of the hook rope 25 is subjected to the force to control the separation of the insulating sheet 251 from the alarm 252. After the thermistor 24 ruptures, when the air pipe 22 and the air supply guide pipe 23 begin to move toward the bottom of the charging box 1 due to the force generated by the deformation of the connecting spring 26, the connecting spring 252 also generates a certain force due to the deformation. After the thermistor 24 ruptures, the connecting spring 26 and the connecting spring 252 begin to The gas guide tube 23 is deformed, so that under the joint action of the connecting spring 26 and the hooking spring 252, the gas guide tube 23 will not be attached to a certain surface of the charging box 1 due to the traction of a certain part of the connecting spring 26 and the hooking spring 252. After the thermistor 24 breaks, the gas guide tube 23 will swing to a certain extent due to the contraction of the connecting spring 26 and the stretching of the hooking spring 252, until the deformation of the connecting spring 26 and the hooking spring 252 stops, and the gas guide tube 23 will be inclined with the bottom of the charging box 1, and then the gas overflowing from the surface of the gas guide tube 23 will cover a larger area in the charging box 1, so that the fire extinguishing effect is maximized;

[0034] After the insulating sheet 251 is separated from the alarm 252, the circuit inside the alarm 252 is connected, and then the alarm 252 starts to work. The sound emitted by the alarm 252 notifies people that a fire has occurred in the charging box 1, so that fire safety personnel can grasp the relevant situation of the fire in time.

[0035] like Figure 5-Figure 6 As shown, the charging box 1 is provided with a detachment module 3 on the side away from the air pipe 22. The detachment module 3 gradually moves away from the placement box 21 from one end located inside the charging box 1 to the end located outside the charging box 1. The detachment module 3 is arranged on the side of the charging box 1 away from the air pipe 22. The detachment module 3 includes a connecting ring 31, a positioning block 32, a positioning spring 33, an airbag strip 34, and a storage tube 35. The connecting ring 31 is sleeved by the side of the charging box 1. One end of the storage tube 35 is coaxially sleeved with the connecting ring 31, and the other end of the storage tube 35 is connected to the charging box 1. The gun 4 is movably connected, the axis of the connecting ring 31 and the storage tube 35 is arranged toward the ground, the outer side of the storage tube 35 is provided with a positioning groove 351, and a plurality of positioning springs 33 are arranged in a circular array at the positioning groove 351, each positioning spring 33 is connected with a positioning block 32, the overall shape of the positioning block 32 is an arc shape, and each positioning block 32 is arranged in a coaxial circular array around the storage tube 35, the inner side of the connecting ring 31 is provided with an airbag groove 311, and the connecting ring 31 is provided with a lead-out through hole 312 on the outer side away from the storage box 21. The two ends of the lead-out through hole 312 are respectively connected to the airbag groove 311 and the inside of the charging box 1. The airbag strip 34 is arranged along the outer side of the airbag groove 311 around the connecting ring 31. The airbag strip 34 is led out from the lead-out through hole 312 to the inside of the charging box 1. An airbag ball 341 is arranged at the end of the airbag strip away from the connecting ring 31. The positioning block 32 is controlled by the positioning spring 33 to contact the airbag strip 34 in the airbag groove 311, and the side of the positioning block 32 is controlled to contact the side of the airbag groove 311. The interior of the airbag ball 341 and the interior of the airbag strip 34 are filled with gas that expands due to heat. The interior of the airbag ball 341 is connected to the interior of the airbag strip 34. In the event of a fire, the gas The balloon 341 is heated, and then the gas in the balloon 341 and the balloon strip 34 is heated and expanded, and then the balloon strip 34 is expanded as a whole, and then each locking block 32 is subjected to the force applied by the balloon strip 34 and moves toward the direction close to the locking spring 33, and then the locking spring 33 contracts, until the locking block 32 completely withdraws from the balloon groove 311, and then the storage tube 35 lacks the support of the connecting ring 31, and then the storage tube 35 together with the connected charging gun 4 is separated from the connecting ring 31 and the charging box 1, so as to avoid the charging gun 4 and the connected end of the wire 5 from being affected by the fire when the fire spreads, and can effectively prevent the fire from getting out of control.

[0036] The working process of this embodiment is as follows: when a fire occurs inside the charging box 1, the temperature inside the charging box 1 rises, and the temperature rise will cause the thermistor block 24 and the thermistor ball 234 to rupture, and the air pipe 22 and the gas guide pipe 23 will then be deformed by the connection spring 26 to shrink and move toward the bottom of the charging box 1, and at the same time, the hooking rope 25 will be displaced along with the gas guide pipe 23, and the hooking rope 25 will drive the insulating sheet 251 to separate from the alarm 252, and at the same time, the bottom end of the hooking spring 252 will move along with the hooking rope 25, and then the hooking spring 252 will be stretched. The connecting spring 26 and the hooking spring 252 jointly control the gas guide pipe 23 to be tilted with the bottom surface of the charging box 1 in the form of not fitting the inner side surface of the charging box 1, and at the same time, the gas in the air pipe 22 will overflow into the charging box 1 due to the loss of the obstruction of the thermistor ball 234, thereby extinguishing the fire point in the charging box 1;

[0037] Simultaneously with the rupture of the thermistor block 24 and the thermistor ball 234, the gas in the airbag ball 341 and the airbag strip 34 expands due to the heat of the airbag ball 341, so that the blocking block 32 extending into the airbag groove 311 is subjected to the thrust generated by the volume expansion of the airbag strip 34, causing the blocking spring 33 connected to the blocking block 32 to contract and deform, so that the blocking block 32 is pushed out of the airbag groove 311 by the airbag strip 34, thereby the storage tube 35 loses the supporting force provided by the connecting ring 31, causing the storage tube 35 together with the charging gun 4 to slide along the axial direction of the connecting ring 31 toward the outside of the charging box 1.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
