Description

Technical Field

[0001] The present application relates to the technical field of charging piles, and in particular to a charging pile and a charging system. Background Art

[0002] As electric vehicles become more and more popular, customers are demanding faster charging speeds. When charging piles are used to quickly charge electric vehicles, the heat generated by the car battery will increase significantly, and the requirements for battery heat dissipation will gradually increase. Electric vehicles generally dissipate heat from the battery through the condenser in the air-conditioning system. Due to the existing thermal management technology and product performance bottlenecks, the cooling capacity of the air-conditioning system is insufficient. At the same time, due to the requirements of styling, the opening at the front of the car is getting smaller and smaller. When charging, there is almost no natural wind blowing through the front opening to the condenser, resulting in insufficient heat dissipation capacity. When the battery temperature is too high, the vehicle will generally alarm and light up the corresponding prompt and warning lights. At this time, the vehicle will also enable overheating protection, reduce the charging current, voltage and power to prevent the battery from continuing to heat up or automatically cut off the power and stop charging, thereby affecting the charging time and charging efficiency of the vehicle.

[0028] Next, the embodiments of this specification are described in detail.

[0029] like Figure 1 and Figure 5 As shown, the charging pile of the utility model includes a main body 10, a water spray assembly 20 arranged on the main body 10, and a driving device 30. The main body 10 is also provided with a detection device 40 and a control assembly 50. The detection device 40 is located at the upper part of the main body 10 and is connected to the driving device 30 and the detection device 40. By arranging the water spray assembly 20 on the charging pile, the direction of the water spray assembly 20 is changed according to the parking position of the car, and the water mist is accurately sprayed to the condenser, thereby improving the heat dissipation capacity of the condenser, preventing the battery temperature from being too high, and improving the charging efficiency.

[0030] The driving device 30 includes a lifting rail 301 and a rotating rocker arm 302, and the lifting rail 301 and the rotating rocker arm 302 are connected to the water spray assembly 20. The lifting rail 301 can change the position of the water spray assembly 20 in the height direction, and the rotating rocker arm 302 can control the direction of the water spray assembly 20.

[0031] The detection device 40 includes a camera 41 and a thermal camera 42. The control component 50 includes a charging pile control device 51, an image preprocessing device 52 and a position calculation device 53. The charging pile control device 51 includes a current detector 511.

[0032] The control component 50 can control the driving device 30 according to the information detected by the detection device 40. The driving device 30 drives the water spraying component 20 to move to the working position, thereby improving the accuracy of the water spraying position.

[0033] The charging pile control device 51 can change the water output of the water spray assembly 20 according to the charging state of the car. The charging pile control device 51 includes a current detector 511, which can detect the magnitude of the current in the circuit to determine the charging speed of the car. When the car is fast charged, the water output of the water spray assembly 20 is increased.

[0034] like Figure 2 As shown, in another embodiment, the driving device 30 includes a first driving device 31 and a second driving device 32. The first driving device 31 is disposed in the main body 10, and the second driving device 32 is disposed in the water spraying assembly 20.

[0035] Please also read Figure 3 As shown, the water spray assembly 20 includes a fixing plate 21 and a spray head 22. The fixing plate 21 is L-shaped. The fixing plate 21 includes an assembly fixing portion 211 and a part fixing portion 212. The assembly fixing portion 211 is vertically arranged, and the part fixing portion 212 extends horizontally outward from the bottom of the assembly fixing portion 211.

[0036] A motor mounting seat 213 and a nozzle mounting shaft 214 are provided on the part fixing portion 212 , and the axes of the motor mounting seat 213 and the nozzle mounting shaft 214 are parallel.

[0037] The first driving device 31 includes a first motor 311, a lead screw 312 connected to the first motor 311, and a nut seat 313 mounted on the lead screw 312. A flexible coupling 314 is connected between the first motor 311 and the lead screw 312 to compensate for the axial deviation of the first motor 311 and the lead screw 312.

[0038] The nut seat 313 is connected to the assembly fixing portion 211 to fix the water spray assembly 20 to the nut seat 313. The first motor 311 can provide two different directions of rotation. After the ball screw is driven, the water spray assembly 20 moves up and down according to the direction of rotation of the first motor 311.

[0039] The second driving device 32 includes a second motor 321, a motor gear 322 provided on the second motor 321, and a nozzle gear 323 provided on the nozzle 22. The second motor 321 is mounted to the motor mounting seat 213. The nozzle gear 323 is connected to the rear section of the nozzle 22, and the nozzle gear 323 is mounted to the nozzle mounting shaft 214.

[0040] The second motor 321 can provide two different directions of rotation. After gear transmission, the nozzle 22 swings left and right according to the direction of rotation of the second motor 321 .

[0041] The nozzle gear 323 is semicircular and is integrally formed with the nozzle 22, so there is no need to add any parts between the nozzle gear 323 and the nozzle 22, thus simplifying the transmission structure. The semicircular nozzle gear 323 allows the nozzle 22 to swing approximately 180 degrees, and the water spraying position can completely cover the front.

[0042] like Figure 4 As shown, the photo camera 41 captures the parking image, and the thermal camera 42 captures the thermal imaging image of the parking side of the car, and sends the parking image and the thermal imaging image to the control component 50.

[0043] The image preprocessing device 52 converts the parking image and the thermal imaging image into a grayscale image. The position calculation device 53 calculates the parking position information of the car based on the two grayscale images, and then calculates the moving distance of the water spray assembly 20 and the swing angle of the spray head 22 based on the parking position information of the car, and sends the numerical values ​​to the first motor 311 and the second motor 321.

[0044] The first motor 311 drives the water spray assembly 20 to move a corresponding distance through the ball screw mechanism, and the second motor 321 drives the spray head 22 to swing a corresponding angle through the gear transmission structure. The spray head 22 can aim at the air intake grille 61 and spray the water mist accurately onto the condenser to dissipate heat from the condenser, reduce energy consumption, and improve the cooling rate of the air conditioning system.

[0045] This embodiment also provides a charging system, such as Figure 5 As shown, the charging system includes a car 60 and the above-mentioned charging pile. An air intake grille 61 is provided at the front end of the car 60.

[0046] After the car 60 is parked, the detection device 40 detects the parking position of the car, the control component 50 receives the information of the detection device 40, and controls the drive device 30 to drive the water spray component 20 to move to the working position. In the working position, the nozzle 22 is roughly flush with the air intake grille 61 in the height direction, and the water spray component 20 faces the air intake grille 61. The water mist accurately passes through the air intake grille 61 and falls on the condenser inside the car, which improves the heat dissipation capacity of the condenser, improves the cooling rate of the air conditioning system, and reduces energy consumption. At the same time, the improvement of the heat dissipation capacity will prevent the battery temperature from being too high, thereby activating the overheating protection to prolong the charging time, thereby improving the charging efficiency.
