Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging, and in particular to a public charging device for new energy vehicles. Background Art

[0002] New energy vehicles are gradually replacing traditional cars and are widely used due to their advantages such as energy saving, emission reduction, environmental protection and pollution-free. In the process of using new energy vehicles, their charging piles are also being built in parking lots, service areas and other places as supporting devices.

[0003] The existing charging pile and the charging gun are connected by a charging cable. When charging, the charging gun is removed from the side wall of the charging pile and inserted into the charging port of the car. After charging is completed, the charging gun is pulled out of the charging port of the car and remounted on the side wall of the charging pile. However, there are various brands and models of new energy vehicles, and the charging port position of each new energy vehicle is different. Therefore, the charging cable needs to be longer to adapt to different models. The longer charging cable will have the following problems:

[0004] 1. The charging cable is long and easily tripped by humans, which can easily cause the charging gun to be pulled off the side wall of the charging pile and break;

[0005] 2. When the user uses the charging pile, the overlong charging cable will fall to the ground, causing the surface of the charging cable to be dragged and worn by the ground for a long time, resulting in leakage;

[0006] 3. Some users do not have the habit of putting the charging gun back after use. The long charging cable is piled on the ground, which is easily damaged by parked cars and passers-by.

[0007] Therefore, a public charging device for new energy vehicles is proposed. Summary of the invention

[0008] The purpose of the present invention is to solve the problems in the prior art and to propose a public charging device for new energy vehicles.

[0017] 1.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Reference Figure 1-4 As shown, a public charging device for new energy vehicles includes a charging pile 1 and a support frame 2 installed on a parking space, the support frame 2 is installed on the rear side of the charging pile 1, the top of the charging pile 1 is connected to a charging cable 11, the end of the charging cable 11 away from the charging pile 1 is connected to a charging gun 12, a cable reeling mechanism 3 is provided on the support frame 2 for reeling in and unreeling the charging cable 11, a groove 5 is provided in the parking space in front of the charging pile 1, and a control mechanism is provided on the groove 5 and the support frame 2.

[0027] In this embodiment, the wire retracting and releasing mechanism 3 includes a pair of rotating plates 31 and a winding drum 34. The top of the support frame 2 is connected to the main shaft 21. The pair of rotating plates 31 are rotatably connected to the two ends of the main shaft 21. Two symmetrically distributed slide grooves 311 are opened on the pair of rotating plates 31. The two slide grooves 311 are slidably connected to a pair of sliders 32. A pair of sliders 32 are rotatably connected to a rotating shaft 33. The winding drum 34 is coaxially connected to the rotating shaft 33. The charging cable 11 is wound on the winding drum 34. The end of the pair of rotating plates 31 away from the main shaft 21 is commonly connected to a fixing rod 37.

[0028] In this embodiment, one end of the rotating shaft 33 is coaxially connected to a gear 35 , and a spur rack 36 is connected to the rotating plate 31 close to the gear 35 , and the spur rack 36 is meshed with the gear 35 .

[0029] In this embodiment, the control mechanism includes a hydraulic cylinder 4, a mounting plate 43 is connected to the support frame 2, the hydraulic cylinder 4 is installed on the mounting plate 43, a pair of rotating plates 31 are connected to one end away from the fixed rod 37 with a connecting shaft 42, the movable end of the hydraulic cylinder 4 is rotatably connected with a connecting rod 41 through a pin shaft, and one end of the connecting rod 41 away from the hydraulic cylinder 4 is rotatably connected to the connecting shaft 42, a plurality of telescopic seats 51 are installed at the bottom of the groove 5, a plurality of the tops of the telescopic seats 51 are connected with a pressure plate 52, a plurality of springs 53 are connected to the bottom of the pressure plate 52, and the lower ends of the plurality of springs 53 are connected to the bottom of the groove 5, a pressure sensor is provided on one of the telescopic seats 51, and the pressure sensor is electrically connected to the control circuit of the hydraulic cylinder 4, when the pressure sensor is pressurized, the hydraulic cylinder 4 is controlled to extend, so that the originally tilted rotating plate 31 is rotated to a horizontal state, and when the pressure sensor is not pressurized, the hydraulic cylinder 4 is controlled to retract, and the rotating plate 31 in the horizontal state is pulled to become a tilted state again.

[0030] In this embodiment, Figure 5 As shown, the middle end of the charging cable 11 is fixed at the middle position of the winding drum 34 as the winding starting point, and then the two ends of the charging cable 11 are respectively wound on the winding drum 34 at both ends. The effect of this winding is that when one end of the charging cable 11 is extended outward, the other end will also be extended outward, and when one end of the charging cable 11 is reeled in, the other end will also be reeled in synchronously.

[0031] In this embodiment, a vent is provided at the bottom of the charging pile 1, and a heat dissipation fin 15 is installed at the vent of the charging pile 1. A fan 14 is installed on the front side of the charging pile 1 to dissipate heat directly to the heat dissipation fin 15. At the same time, the wind of the fan 14 is also directed towards the parking space in front of the charging pile 1. Since the batteries of new energy vehicles are mostly installed at the bottom of the vehicle and will also generate heat during charging, the wind from the fan 14 can dissipate heat for the bottom battery of the new energy vehicle being charged while dissipating heat for the charging pile 1.

[0032] In this embodiment, the rotating plate 31, the slider 32, the rotating shaft 33, the winding drum 34 and the fixing rod 37 in the wire retracting and unwinding mechanism 3 are all made of aluminum alloy material, which has the advantages of light weight, high strength and good corrosion resistance.

[0033] The working process and principle of the present invention are as follows:

[0034] During use, after the vehicle is driven to the parking space, the tire of the car will be located on the pressure plate 52, and the weight of the car will press the pressure plate 52 downward, triggering the pressure sensor on the telescopic seat 51, which will control the hydraulic cylinder 4 to extend, and push the rotating plate 31 to rotate through the connecting rod 41, so that the originally inclined rotating plate 31 is rotated to a horizontal state. At this time, the owner can pull the charging gun 12 according to the position of the charging port on the car, so that the slider 32 slides in the slide groove 311, and under the meshing action of the gear 35 and the spur rack 36, the winding drum 34 moves and rotates, and at the same time releases the two ends of the charging line 11, so that the charging distance is longer. During the charging process, the charging line 11 is in a suspended state and will not fall to the ground, avoiding the problem of surface wear caused by friction with the ground. At the same time, the fan 14 is turned on. When the charging pile 1 is dissipated, the wind will blow into the bottom of the new energy vehicle to dissipate the heat of the battery being charged, thereby playing a charging protection effect.

[0035] After charging is completed, the user only needs to unplug the charging gun 12 to leave. After the car leaves the pressure plate 52, the pressure plate 52 returns to its original position under the action of the spring 53, and the pressure sensor is no longer under pressure, which controls the hydraulic cylinder 4 to retract, pulling the rotating plate 31 in the horizontal state to become an inclined state. Under the action of its own gravity, the winding drum 34 rolls along the slide groove 311 in the direction of the main shaft 21, and at the same time reels the charging cable 11 to achieve automatic recovery of the charging cable 11, and the charging gun 12 is also in a suspended state, which not only avoids the risk of the charging cable being easily tripped by humans due to its long length, and the risk of the charging gun being pulled off the side wall of the charging pile and being broken, but also prevents the charging cable 11 from being piled on the ground after completion, which is easily damaged by being crushed by parked cars and stepped on by passers-by.

[0036] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
