Description

Technical Field

[0001] The present invention relates to the technical field of intelligent charging piles, and particularly to an intelligent charging pile with an anti-accident function. Background Technique

[0002] An intelligent charging pile is a charging device designed specifically for electric vehicles, integrating multiple intelligent management systems, capable of realizing functions such as remote monitoring, data statistics, user identity recognition, etc. The intelligent charging pile system can automatically adjust the charging power according to the battery state of the electric vehicle to ensure charging is completed in a shorter time, saving users' time and power resources. Through Internet of Things technology, remote monitoring and management can be achieved. Operators can understand the operating status of the charging pile in real time through the background system, handle faults in a timely manner, and improve service quality. It has multiple built-in safety protection mechanisms, including overcurrent protection, overvoltage protection, short-circuit protection, etc., effectively avoiding potential safety hazards during the charging process. Intelligent charging piles play an increasingly important role in modern life. Understanding how to use them correctly and keep the charging equipment in good condition is crucial for enhancing the charging experience of electric vehicle owners.

[0003] For example, an intelligent new energy vehicle charging pile disclosed in the application publication number CN116373648A has a structure including a base and a charging pile body installed on the base. A motor is installed inside the charging pile body, and the output end of the motor is fixedly connected to a first rotating shaft. A winding wheel is installed on the first rotating shaft. However, there are still some problems in this application: Although this application can avoid excessive reverse driving, if there is a human operation error and the brake is accidentally stepped on the accelerator, at this time, the vehicle has a large inertia, and under the action of inertia, the vehicle still has a high probability of directly hitting the charging pile, still having a high degree of danger.

[0004] When a short circuit occurs accidentally in the internal circuit of the charging pile, it is easy to catch fire, with a high degree of danger. After the vehicle finishes charging, there is an accidental situation where the vehicle owner forgets to unplug the charging gun. At this time, when the vehicle starts to leave, when the vehicle pulls forcefully, the cable of the charging gun is easily pulled off, and the charging pile is damaged, increasing the risk of electric leakage.

It should be noted that temperature sensors are installed inside and outside the charging pile body 1, and the temperature sensor is electrically connected to the driving motor 33 and the fire extinguisher 19.

[0027] In the present invention, the drive shaft of the drive motor 33 rotates through the rotating plate 17 and is coaxially connected to the rotating rod 31. An arc-shaped plate 20 for protecting the drive motor 33 is installed outside the rotating plate 17. An air outlet nozzle 38 is installed at the outlet of the fire extinguisher 19. A slide hole 39 matching the air outlet nozzle 38 is provided through the inner bottom of the strip-shaped through hole 18.

It is worth mentioning that the induction mechanism 22 includes a glass tube 23. A sealing plate 24 is hermetically and slidably connected inside the glass tube 23. Mercury is filled on one side of the glass tube 23 where the sealing plate 24 is located. A contact plate 26 is arranged on the other side of the glass tube 23 where the sealing plate 24 is located and is set to be vacuum.

An annular tooth groove meshing with the rotating gear 37 is provided on the bottom plate 15. The contact plate 26 is electrically connected to the rotating motor 36.

[0028] Through the above technical features: When a fire breaks out inside the charging pile body 1, at this time, the temperature sensor inside the charging pile body 1 detects high temperature. The drive motor 33 drives the rotating rod 31 to rotate. The rotating rod 31 drives the two adjusting screws 28 to rotate. The two adjusting screws 28 drive the two fire extinguishers 19 to move through the adjusting blocks 29 until they reach the appropriate positions. At this time, the air outlet nozzle 38 corresponds to the matching hole 40. The air outlet nozzle 38 opens the valve, and the fire extinguishing material in the air outlet nozzle 38 can extinguish the fire inside the charging pile body 1. When a fire breaks out outside the charging pile body 1, the temperature on the side of the fire is relatively high. The mercury expands when heated and pushes the sealing plate 24 to move until the sealing plate 24 abuts against the contact plate 26. At this time, the rotating motor 36 drives the rotating gear 37 to rotate. The rotating gear 37 drives the rotating plate 17 to rotate. The rotating plate 17 drives the fire extinguisher 19 to move until the air outlet nozzle 38 on the fire extinguisher 19 corresponds to the air outlet holes 16. The air outlet nozzle 38 opens the valve. Most of the fire extinguishing material in the air outlet nozzle 38 is sprayed out from the current air outlet holes 16 for extinguishing the fire. A small amount of fire extinguishing material is sprayed out from the other air outlet holes 16 through the inside of the box body 14 to prevent the spread of the fire, improving the safety of using the charging pile.

[0029] When the vehicle accidentally fails to unplug the gun, in order to avoid damage to the charging pile, a disengagement mechanism 4 is provided. The disengagement mechanism 4 includes a winding box 42 fixedly mounted on the charging pile body 1, and a winding reel 41 is rotatably mounted in the winding box 42. The winding reel 41 is provided with a slot 45, and a cable 43 is inserted in the slot 45. The cable 43 is wound around the outside of the winding reel 41. It should be noted that a connector connected to the cable 43 is provided in the slot 45, and the end of the cable 43 away from the winding reel 41 passes through the winding box 42 and is connected to the charging gun 44. A limiting ring 46 is installed on the part of the cable 43 located in the slot 45, and a buffer groove 47 is provided on the inner wall of the slot 45. A wedge block 49 is slidably connected in the buffer groove 47. Furthermore, a smooth inclined surface is provided at one end of the wedge block 49 away from the central axis of the winding reel 41, and the inclined surface faces the direction away from the rack 57. A traction rope 60 is installed at one end of the wedge block 49. A buffer spring 50 is provided on the outer sleeve of the guide rope 60, and the two ends of the buffer spring 50 are respectively connected to the wedge block 49 and the inner wall of the buffer groove 47. A cavity 48 is provided in the winding disk 41, and a rack 57 is slidably connected in the cavity 48. A counterweight block 58 is installed on the rack 57, and a return spring 59 is installed between the counterweight block 58 and the inner wall of the cavity 48. A winding shaft 51 is rotatably installed in the cavity 48, and a winding roller 56 is installed outside the winding shaft 51. The end of the traction rope 60 away from the wedge block 49 slides through the winding disk 41 and is fixedly wound with the winding roller 56. The winding shaft 51 and the rack 57 are connected by a driving mechanism 53. It should be noted that the driving mechanism 53 includes a transmission shaft 52 rotatably connected to the inner wall of the cavity 48, a driving wheel 54 is installed outside the transmission shaft 52, and the rack 57 is meshingly connected to the driving wheel 54. A driven wheel 55 is installed on the winding shaft 51, and the driven wheel 55 is meshingly connected to the driving wheel 54.

[0030] Through the above technical features: When the vehicle is charged and the gun is not pulled out accidentally, the vehicle starts to pull the charging gun 44, and the charging gun 44 pulls the cable 43, and the cable 43 will drive the winding drum 41 to rotate. When the winding drum 41 rotates, under the action of centrifugal force, the counterweight block 58 moves, and the counterweight block 58 drives the driving wheel 54 to rotate through the rack 57, and the driving wheel 54 drives the winding shaft 51 to rotate through the driven wheel 55, and the winding shaft 51 drives the winding roller 56 to rotate, and the winding roller 56 reels the traction rope 60, and the traction rope 60 pulls the wedge block 49 to move, so that the wedge block 49 does not limit the limit ring 46. When the length of the cable 43 reaches the limit, the cable 43 and the slot 45 will directly disengage, avoiding the impact of the pulling of the cable 43 on the charging pile body 1, avoiding damage to the charging pile body 1, reducing losses, and reducing the probability of risk.

[0031] Working principle: When the vehicle speed is detected to be relatively high: The lifting motor 8 drives the two lifting screw rods 6 to rotate. The two lifting screw rods 6 drive the lifting block 7 to move up and down. The lifting block 7 drives the charging pile body 1 to move up and down until the charging pile body 1 is received into the embedded box 5. At this time, it is possible to prevent a vehicle with a relatively high speed from colliding with the charging pile body 1 and avoid damage to the charging pile. When a fire breaks out in the charging pile: When a fire breaks out inside the charging pile body 1, at this time, the temperature sensor inside the charging pile body 1 detects high temperature. The drive motor 33 drives the rotating rod 31 to rotate. The rotating rod 31 drives the two adjusting screw rods 28 to rotate. The two adjusting screw rods 28 drive the two fire extinguishers 19 to move through the adjusting block 29 until they reach the appropriate positions. At this time, the air outlet nozzle 38 corresponds to the matching hole 40. The air outlet nozzle 38 opens the valve, and the fire extinguishing material inside the air outlet nozzle 38 can extinguish the fire inside the charging pile body 1. When a fire breaks out outside the charging pile body 1, the temperature on the side of the fire is relatively high. The mercury expands when heated and pushes the sealing plate 24 to move until the sealing plate 24 abuts against the contact plate 26. At this time, the rotating motor 36 drives the rotating gear 37 to rotate. The rotating gear 37 drives the rotating plate 17 to rotate. The rotating plate 17 drives the fire extinguisher 19 to move until the air outlet nozzle 38 on the fire extinguisher 19 corresponds to the air outlet hole 16. The air outlet nozzle 38 opens the valve, and most of the fire extinguishing material inside the air outlet nozzle 38 sprays out from the current air outlet hole 16 for fire extinguishing. A small amount of fire extinguishing material sprays out from other air outlet holes 16 through the inside of the box body 14 to prevent the spread of the fire and improve the safety of using the charging pile. When the vehicle does not unplug the charging gun after charging: When the vehicle accidentally does not unplug the charging gun after charging, the vehicle starts to pull the charging gun 44. The charging gun 44 pulls the cable 43, and the cable 43 will drive the winding disc 41 to rotate. When the winding disc 41 rotates, under the action of centrifugal force, the counterweight block 58 moves. The counterweight block 58 drives the driving wheel 54 to rotate through the rack 57. The driving wheel 54 drives the winding shaft 51 to rotate through the driven wheel 55. The winding shaft 51 drives the winding roller 56 to rotate. The winding roller 56 winds the towing rope 60. The towing rope 60 pulls the wedge block 49 to move, so that the wedge block 49 does not limit the limit ring 46. When the length of the cable 43 reaches the limit, the cable 43 will directly disengage from the slot 45, avoiding the impact on the charging pile body 1 caused by the pulling of the cable 43, avoiding damage to the charging pile body 1, reducing losses, and reducing the probability of risk occurrence.
