Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to an electric vehicle charging pile controller with an alarm protection function. Background Art

[0002] The development and utilization of new energy sources are receiving increasing attention. In recent years, electric vehicles, as a green means of transportation with broad development prospects, will be popularized at an extremely rapid pace in the future, and the future market prospects are also huge. At present, the Chinese government is actively promoting the application and development of new energy vehicles. Charging stations, as an important supporting infrastructure necessary for the development of electric vehicles, have very important social and economic benefits. A campaign to build electric vehicle charging / swapping stations has been launched nationwide. The existing publication number: CN118876769A is a smart charging pile with collision warning and automatic protection, including a shell, and electrical components are installed inside the shell. The present invention monitors the position of the vehicle through a distance sensor, and the buzzer alarm will increase the alarm volume according to the real-time distance. When an accidental collision occurs, when the corner protection frame and the protective plate are slightly hit, the push rod on one side will squeeze the spring to absorb the slight impact force. When a stronger collision occurs, the speed signal transmitter and the speed signal receiver will monitor the speed of the collision and control the modular airbag in the corresponding direction to open, and the circuit breaker controller cuts off the current of the power cable to protect the electrical components. The modular airbag can be quickly replaced after use, reducing the cost of use and replacement. In this way, the pre-collision warning and post-collision protection functions can be performed, reducing the problem of dangerous situations that are prone to occur after the charging pile is hit. The existing charging pile controllers have the following main disadvantages: 1. Existing charging pile controllers rely on passive protection after a collision, but cannot prevent failures caused by abnormal temperatures. High temperatures accelerate the aging of electronic components, shortening the life of the equipment. Extreme high temperatures may cause fires and lead to safety accidents. 2. If the vehicle hits the charging pile due to improper operation, especially when the hook is scratched when reversing, the charging pile will tilt. The tilt will cause the power cord to be forcibly pulled, and the insulation layer will be worn, which may cause phase short circuit or ground leakage, causing harm to the user. Summary of the Invention

[0003] The object of the present invention is to provide an electric vehicle charging pile controller with an alarm protection function to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions: Provided is an electric vehicle charging pile controller with an alarm protection function, comprising a charging pile controller, a protection mechanism connected to the charging pile controller, and an alarm component externally connected to the protection mechanism; wherein The protection mechanism includes: A temperature control component is fixedly connected to the charging pile controller, the temperature control component is connected to a temperature sensing component, and the temperature sensing component is connected to a control component.

[0005] Furthermore, the temperature control component includes: A temperature conduction plate is fixedly connected to the outside of the charging pile controller. A cooling trough is fixedly connected to the temperature conduction plate. Coolant heat dissipation troughs are respectively provided on both sides of the cooling trough. The coolant heat dissipation trough is fixedly connected to the temperature conduction plate. One end of the coolant heat dissipation trough is connected to both sides of one end of the cooling trough. A water pump is also fixedly connected to the temperature conduction plate.

[0006] Furthermore, a rotating shaft is rotatably connected to the coolant heat dissipation tank, one end of the rotating shaft is fixedly connected to an impeller, and the other end of the rotating shaft is fixedly connected to fan blades, the impeller is located in the coolant heat dissipation tank, and the fan blades are located outside the coolant heat dissipation tank.

[0007] Furthermore, the temperature sensing component includes: A temperature sensing tube, the temperature sensing tube is fixedly connected to the cooling tank, a piston is slidably connected in the temperature sensing tube, a spring is connected to the piston, the piston is fixedly connected to one end of the push rod, the other end of the push rod is fixedly connected to a slide groove, the two ends of the slide groove are respectively fixedly connected to one end of the L-shaped pull rod, the other end of the L-shaped pull rod is fixedly connected to a baffle, and the baffle is slidably connected to the position where the coolant heat dissipation tank and the cooling tank are connected.

[0008] Furthermore, a protective cover is fixedly connected to the temperature conduction plate; and The control component includes: The angle rod is rotatably connected to the protective cover, one end of the angle rod is slidably connected in a slide groove, and the protective cover is fixedly connected with an arc rod.

[0009] Furthermore, the alarm component includes: A pendulum rod, the lower end of which is fixedly connected to a pendulum ball, the pendulum rod is rotatably connected to the protective cover, the upper end of the pendulum rod is slidably connected to the second slide groove, the two sides of the second slide groove are respectively fixedly connected to one end of two slide rods, the slide rod is slidably connected to the protective cover, a spring second is sleeved on the slide rod, the other end of the slide rod is fixedly connected to a triangular block, both sides of the second slide groove are fixedly connected to a press switch, the press switch is fixedly connected to a lock buckle, and the protective cover is also fixedly connected to a buzzer.

[0010] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects: 1. When the temperature of the charging pile rises, the temperature conduction plate is fixedly connected to the charging pile, and the temperature is conducted to the temperature conduction plate, thereby increasing the temperature of the coolant in the cooling tank, causing the temperature sensing component to work, thereby driving the control component to deflect, causing the water pump to work, and the coolant is pumped out of the cooling tank through the water pump, and then transported from the other end of the coolant heat dissipation tank to its interior, and then re-flowed into the cooling tank from one end of the coolant heat dissipation tank to cool the charging pile controller. When the coolant flows in the coolant heat dissipation tank, due to its narrow channel, the cooling effect on the coolant is better. The coolant heat dissipation tank is wavy, so the coolant flows inside it for a longer time, enhancing the heat dissipation effect of the coolant. The temperature conduction plate absorbs heat in real time and actively cools down through the coolant circulation. Temperature sensing component: The thermal expansion in the temperature sensing tube drives the piston, and the linked push rod adjusts the coolant flow rate to achieve mechanical temperature control without power participation. Compared with electronic temperature control sensors, the mechanical structure has stronger resistance to electromagnetic interference and lower failure rate. The dynamic circulation efficiency of the coolant far exceeds that of traditional fan heat dissipation. 2. When the charging pile deflects at an angle, the pendulum ball drives the pendulum arm to deflect, causing the second slide groove to push the slide rod to slide, and the second spring is compressed or stretched. At the same time, the triangular block pushes the lock to move, squeezing the press switch, and the buzzer sounds an alarm. When the triangular block enters the recessed position of the lock, the triangular block is locked and can be unlocked by pressing the lock to release the alarm. The protective mechanism and alarm component are integrated into the charging pile controller, and signal transmission is achieved through a mechanical transmission chain, which reduces the number of electronic sensors, reduces manufacturing costs, and improves response speed. When the charging pile issues an alarm, it reminds users to pay attention to the leakage of the charging pile and handle it with care to avoid electric shock. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0015] Reference Figure 1-2As shown, an electric vehicle charging pile controller with an alarm protection function includes a charging pile controller 1, a protection mechanism 2 is connected to the charging pile controller 1, and an alarm component 3 is externally connected to the protection mechanism 2; The protection mechanism 2 includes: The temperature control component 21 is fixedly connected to the charging pile controller 1 . The temperature control component 21 is connected to a temperature sensing component 22 , and the temperature sensing component 22 is connected to a control component 23 .

[0016] During the charging process, when the temperature of the charging pile is too high, the temperature sensing component 22 works. Through the operation of the temperature sensing component 22, the control component 23 opens the temperature control component 21 to cool the charging pile and reduce the temperature. When the temperature drops below the threshold, the temperature control component 21 resets, thereby driving the control component 23 to reset. At this time, the temperature control component 21 stops working. When the charging pile shakes at a large angle due to strong winds or other reasons, the alarm component 3 works.

[0017] Reference Figure 3-5 As shown in FIG11 , the temperature control component 21 includes: The temperature conduction plate 211 is fixedly connected to the outside of the charging pile controller 1. A cooling tank 212 is fixedly connected to the temperature conduction plate 211. Cooling liquid heat dissipation tanks 213 are respectively provided on both sides of the cooling tank 212. The cooling liquid heat dissipation tank 213 is fixedly connected to the temperature conduction plate 211. One end of the cooling liquid heat dissipation tank 213 is connected to both sides of one end of the cooling tank 212. A water pump 214 is also fixedly connected to the temperature conduction plate 211.

[0018] When the temperature of the charging pile rises, since the temperature conduction plate 211 is fixedly connected to the charging pile, the temperature is conducted to the temperature conduction plate 211, thereby increasing the temperature of the coolant in the cooling tank 212, causing the temperature sensing component 22 to work, thereby driving the control component 23 to deflect, causing the water pump 214 to work, and the coolant is pumped out of the cooling tank 212 through the water pump 214, and then transported from the other end of the coolant heat dissipation tank 213 to its interior, and then flows back into the cooling tank 212 from one end of the coolant heat dissipation tank 213 to cool the charging pile controller 1. When the coolant flows in the coolant heat dissipation tank 213, due to its narrow channel, the cooling effect on the coolant is better. The coolant heat dissipation tank 213 is wavy, so the coolant flows inside it for a longer time, thereby enhancing the heat dissipation effect on the coolant.

[0019] The coolant heat dissipation groove 213 is rotatably connected to a rotating shaft, one end of the rotating shaft is fixedly connected to an impeller 2131, and the other end of the rotating shaft is fixedly connected to a fan blade 2132. The impeller 2131 is located inside the coolant heat dissipation groove 213, and the fan blade 2132 is located outside the coolant heat dissipation groove 213.

[0020] When the coolant flows in the coolant heat dissipation groove 213, it drives the impeller 2131 to rotate, and then the shaft drives the fan blades 2132 to rotate. The rotation of the fan blades 2132 enhances the air circulation outside the coolant heat dissipation groove 213, thereby increasing the heat dissipation efficiency of the coolant to a certain extent.

[0021] Reference Figure 6-7 As shown, the temperature sensing component 22 includes: The temperature sensing tube 221 is fixedly connected to the cooling tank 212, and a piston 222 is slidably connected inside the temperature sensing tube 221. A spring 223 is connected to the piston 222. The piston 222 is fixedly connected to one end of the push rod 224, and the other end of the push rod 224 is fixedly connected to a slide 225. The two ends of the slide 225 are respectively fixedly connected to one end of the L-shaped pull rod 226, and the other end of the L-shaped pull rod 226 is fixedly connected to a baffle 227. The baffle 227 is slidably connected to the position where the coolant heat dissipation tank 213 is connected to the cooling tank 212.

[0022] When the coolant temperature exceeds the threshold, the inert gas in the temperature sensing tube 221 expands, thereby pushing the piston 222 upward, causing the push rod 224 to drive the slide 225 to move together, and the movement of the slide 225 drives the L-shaped pull rod 226 to move, pulling the baffle 227 to move, so that the baffle 227 is moved away from the position where the coolant heat dissipation groove 213 is connected to the cooling groove 212.

[0023] Reference Figure 8 As shown, a protective cover 228 is fixedly connected to the temperature conducting plate 211; and The control component 23 includes: The folding rod 231 is rotatably connected to the protective cover 228 , one end of the folding rod 231 is slidably connected in the slide groove 225 , and the protective cover 228 is fixedly connected with an arc rod 232 .

[0024] When the slide 1 225 moves, it drives the angle rod 231 to rotate, so that the other end of the angle rod 231 enters the bottom of the arc rod 232 and contacts the arc rod 232, so that the water pump 214 is energized, and the water pump 214 extracts the coolant in the cooling tank 212, and then transports it to the coolant heat dissipation tank 213, and then flows back into the cooling tank 212 from the position where the coolant heat dissipation tank 213 and the cooling tank 212 are connected.

[0025] Reference Figure 9-10 As shown, the alarm component 3 includes: The pendulum rod 31 has a pendulum ball 32 fixedly connected to its lower end, the pendulum rod 31 is rotatably connected to the protective cover 228, the upper end of the pendulum rod 31 is slidably connected to the second slide groove 33, the two sides of the second slide groove 33 are respectively fixedly connected to one end of two slide rods 34, the slide rods 34 are slidably connected to the protective cover 228, a second spring 35 is sleeved on the slide rod 34, the other end of the slide rod 34 is fixedly connected to a triangular block 36, both sides of the second slide groove 33 are fixedly connected to a press switch 37, a lock buckle 38 is fixedly connected to the press switch 37, and a buzzer 39 is also fixedly connected to the protective cover 228.

[0026] When the charging pile deflects at an angle, the pendulum ball 32 drives the pendulum rod 31 to deflect, causing the second slide groove 33 to push the slide rod 34 to slide, and the second spring 35 to be compressed or stretched. At the same time, the triangular block 36 pushes the lock 38 to move, squeezing the press switch 37, and the buzzer 39 emits an alarm sound. When the triangular block 36 enters the recessed position of the lock 38, the triangular block 36 is locked and can be unlocked by pressing the lock 38, thereby releasing the alarm.
