Description

Technical Field

[0001] This invention belongs to the field of electric vehicle charging technology, specifically a city electric vehicle charging system. Background Technology

[0002] With increasing environmental awareness and the development of new energy vehicles, the use of electric vehicles is growing, and the installation areas of electric vehicle charging stations are becoming more widespread. Charging stations are now commonly found in residential areas, making them an indispensable electrical facility in modern communities. Currently, most charging stations are always installed on the ground, exposed to sun, wind, and rain regardless of whether they are in use. Furthermore, some inexperienced drivers may collide with charging stations when reversing to bring the charging port close, damaging both the charging station and the vehicle, resulting in significant economic losses. Therefore, existing technologies include measures to install charging stations underground and to mount charging guns on charging sheds.

[0003] In the prior art, for example, the invention patent with application number CN202110091397.X, "Buried Charging Pile Based on Lifting Mechanism," describes a technical solution: a buried charging pile based on a lifting mechanism. It includes a device well buried in the ground, with a charging device installed inside the well; the device well includes a buried body, with a charging protection body installed inside, and a top protective cover connected to the top of the charging protection body; the charging device includes a charging shell, with a moving body and a lifting body installed inside the charging shell. However, placing the charging pile underground requires additional installation wells, increasing workload; furthermore, underground charging is susceptible to rainwater erosion, requiring attention to waterproofing; and there is also the problem that if the lifting position is blocked, the charging pile cannot be raised, thus preventing charging.

[0004] In the prior art, for example, the invention patent with application number "CN202211279897.7" entitled "A winding system for a suspended charging cable of a charging pile" describes a technical solution: "A winding system for a suspended charging cable of a charging pile includes a support arm, a winding device, and a charging cable; the charging cable includes a fixed section cable, a wound section cable, and a suspended section cable; the wound section cable is wound on the winding device, and a section of the wound section cable is suspended downwards as the suspended section cable; the end of the suspended section cable is connected to a charging head." However, because the charging cable is wound on the winding device without additional fixation, when the charging cable is lowered or retracted by the winding device, it is susceptible to swaying due to external forces (such as wind), which could harm vehicles or people, resulting in safety hazards during the use of the charging gun.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 5 As shown, an urban electric vehicle charging system includes a charging cabinet 100, a charging gun 200, a drive system, and a charging shed 300. The charging cabinet 100 is installed inside the charging shed 300. The charging cabinet 100 is connected to an external power grid to convert the voltage of the external power grid and outputs it through the charging gun 200. The charging gun 200 is connected to the charging gun 200 through a connecting cable 500. The charging gun 200 is used to connect to the electric vehicle to charge the electric vehicle.

[0035] like Figure 1 As shown, a crossbeam 400 is provided above the charging shed 300, and a connecting line 500 is provided inside the crossbeam 400. A drive system is provided below the crossbeam 400, and a charging gun 200 is fixedly mounted on the drive system. The drive system is used to drive the charging gun 200 and the connecting line 500 to move, so that the charging gun 200 can be connected to the electric vehicle.

[0036] like Figure 2 As shown, the drive system includes a first drive component and a second drive component; the first drive component is used to drive the charging gun 200 to rotate and / or move up and down; the second drive component is used to connect the charging gun 200 to the electric vehicle; the second drive component is fixedly mounted on the first drive component.

[0037] The technical solution provided in this invention simplifies the use of the charging gun 200 by connecting it to the charging cabinet 100 using a connecting cable 500, and then lowers the charging gun 200 and connecting cable 500 from the crossbeam 400 via a drive system. This makes the charging gun 200 easier to use and allows for more flexible installation of the charging cabinet 100, enabling multiple charging cabinets 100 to be installed together, saving space in the charging shed 300. Furthermore, since the connecting cable 500 is routed through the crossbeam 400 above the charging shed 300, it will not be worn down on the ground or run over by electric vehicles during charging, thus preventing damage to the connecting cable 500.

[0038] The first and second drive components enable the charging gun 200 to move quickly, thus rapidly charging the electric vehicle and ensuring charging efficiency. Furthermore, the technical solution provided in this invention does not suffer from erosion by rainwater or blockage. Fixing the charging gun 200 and connecting cable 500 to the drive system prevents them from wobbling during vertical movement, thus avoiding damage to the vehicle or personnel, and demonstrates promising application prospects.

[0039] Example 2

[0040] This embodiment is a further refinement of Embodiment 1. For example... Figure 5 As shown, the first drive assembly includes a base 600 and a first connecting column 700; wherein, the base 600 is fixedly disposed below the crossbeam 400, a first motor 800 is disposed inside the base 600, and a first connecting shaft 900 is disposed on the output shaft of the first motor 800.

[0041] The first connecting post 700 is sleeved on the outside of the base 600 and is rotatably connected to the base 600. A connecting plate 110 is fixedly provided at the end of the first connecting post 700, and a second connecting shaft is provided in the middle of the connecting plate 110. The second connecting shaft is fixedly connected to the first connecting shaft 900 and is used to drive the first connecting post 700 to rotate. A mounting part is provided at the end of the first connecting post 700, and a first driving member 111 and a second connecting post 112 are also provided inside the first connecting post 700. The first driving member 111 is fixedly provided on the mounting part. The first driving assembly is connected to the second connecting post 112 and drives the second connecting post 112 to slide inside the first connecting post 700. The second driving assembly is fixedly provided on the second connecting post 112.

[0042] like Figure 5 and Figure 6 As shown, the end of the first connecting post 700 is provided with a mounting part, which includes a first mounting part 126 and a second mounting part 127; wherein, the first mounting part 126 is fixedly connected to the first connecting post 700, the lower part of the first mounting part 126 is used to fixally connect the first driving member 111; the upper part of the first mounting part 126 is used to fix the connecting plate 110; the first mounting part 126 and the connecting plate 110 are connected by bolts.

[0043] The second mounting part 127 is sleeved on the outside of the base 600, and the end of the base 600 is provided with a limiting boss 128 corresponding to the second mounting part 127. The second mounting part 127 is connected to the first mounting part 126 by bolts.

[0044] Furthermore, the second mounting part 127 is rotatably connected to the base 600.

[0045] Furthermore, the first driving component 111 is either a pneumatic cylinder or a hydraulic cylinder.

[0046] Furthermore, the connecting plate 110 is positioned between the first mounting part 126 and the second mounting part 127, and the first mounting part 126, the second mounting part 127, and the connecting plate 110 are connected by bolts.

[0047] The second drive assembly includes a second drive component 113, a first connecting rod 114, and a fixing assembly;

[0048] One end of the second driving member 113 is rotatably connected to the fixed component, and the other end of the second driving member 113 is provided with a sliding component. The second driving member 113 is rotatably connected to the sliding component, and the sliding component is provided on the first connecting rod 114.

[0049] A second connecting rod 115 is also provided at the end of the first connecting rod 114, and the second connecting rod 115 is rotatably connected to the first connecting rod 114.

[0050] like Figure 3 As shown, the fixing assembly includes a first fixing ring 116 and a second fixing ring 117, both of which are fixedly mounted on the second connecting post 112; the second driving member 113 is rotatably connected to the first fixing ring 116, and the first connecting rod 114 is rotatably connected to the second fixing ring 117.

[0051] By setting the first fixing ring 116 and the second fixing ring 117 on the second connecting post 112, when the first driving member 111 drives the second connecting post 112 to move up and down, the first fixing ring 116 and the second fixing ring 117 of the fixing assembly can also drive the second connecting rod 115 to move up and down, thereby driving the charging gun 200 to move up and down.

[0052] The first driving member 113 is rotatably connected to the first fixed ring 116, and the first connecting rod 114 is rotatably connected to the second fixed ring 117.

[0053] When the second driving member 113 retracts, the second driving member 113 rotates around the first fixed ring 116 and drives the sliding assembly to slide on the second connecting rod 115, thereby causing the second connecting rod 115 to rotate around the second fixed ring 117, so that the second connecting rod 115 retracts.

[0054] When the second driving member 113 extends, the second driving member 113 rotates around the first fixed ring 116 and drives the sliding assembly to slide in the opposite direction on the second connecting rod 115, so that the second connecting rod 115 rotates around the second fixed ring 117, causing the second connecting rod 115 to unfold.

[0055] Furthermore, the second drive component 113 is either a pneumatic cylinder or a hydraulic cylinder.

[0056] like Figure 4 As shown, a second motor 118 is provided at one end of the second connecting rod 115, and the second motor 118 is used to rotate the second connecting rod 115; a mounting platform 119 is provided at the other end of the second connecting rod 115, and a fixing part 120 is provided on the mounting platform 119, which is used to fix the charging gun 200.

[0057] The mounting platform 119 is rotatably connected to the fixing part 120. A third motor 121 is provided below the mounting platform 119. The third motor 121 is used to drive the fixing part 120 to rotate.

[0058] like Figure 4 As shown, a length compensation component is also provided on the second connecting rod 115; the length compensation component includes a sliding rod 122 and a third driving member 123; wherein, the third driving member 123 is fixedly disposed inside the second connecting rod 115, one end of the sliding rod 122 is slidably disposed inside the second connecting rod 115, and the third driving member 123 drives the sliding rod 122 to slide.

[0059] A handle 124 is also provided on one side of the second connecting rod 115. The handle 124 is used for manual traction to drive the system.

[0060] The end of the sliding rod 122 is also provided with a flange 125, and the sliding rod 122 is detachably connected to the mounting platform 119 through the flange 125.

[0061] The working principle of this invention is as follows: In use, the electric vehicle is first parked at a designated parking spot. The first motor 800 drives the first connecting column 700 and the second connecting column 112 to rotate, thereby adjusting the angles of the first connecting column 700 and the second connecting column 112. Then, the first driving component 111 drives the second connecting column 112 to slide inside the first connecting column 700, thereby adjusting the height of the second driving component, and thus adjusting the height of the charging gun 200. The first driving component completes the adjustment of the height of the charging gun 200 and the initial adjustment of the angle of the charging gun 200.

[0062] Then, by extending the output shaft of the second driving component 113, the sliding component is driven to slide on the first connecting rod 114, thereby causing the first connecting rod 114 to rotate around the second fixed ring 117, and the first connecting rod 114 is lowered, thereby adjusting the height and angle of the first connecting rod 114, thus completing the adjustment of the height of the charging gun 200.

[0063] Then, the second motor 118 drives the second connecting rod 115 to rotate, adjusting the angle of the second connecting rod 115, and the third motor 121 drives the fixing part 120 to rotate, so that the charging gun 200 can be aligned with the charging port of the electric vehicle to start charging.

[0064] Furthermore, the connecting cable 500 has a certain amount of slack (the amount of slack can be determined according to actual use, for example, 100cm to 150cm). By leaving a certain amount of slack in the connecting cable 500, the charging gun 200 can be not only fixed on the fixing part 120, but can also be manually pulled and used to charge the electric vehicle.

[0065] Example 3

[0066] This embodiment provides a specific usage method. The charging system also includes a camera module, a data processing module, and a data transmission module. The camera module is located below the crossbeam 400 or the charging shed 300. The camera module determines whether the electric vehicle is parked according to a fixed parking standard, which is that the rear of the electric vehicle is placed close to the charging gun 200 of the charging system.

[0067] Once the camera module confirms that an electric vehicle has parked in the parking space according to the parking standards, it sends the parking data to the data processing module for confirmation and processing. After the data processing module confirms that an electric vehicle has parked, it sends a signal to the drive system through the data transmission module. The drive system then drives the charging gun 200 to lower and approach the electric vehicle as instructed by the camera module (this process can be manual or automatic). Finally, the charging gun 200 can be moved manually by pulling the handle 124, allowing it to charge the electric vehicle.

[0068] The electric vehicle can also be automatically charged via a positioning module on the charging gun 200. The positioning module includes a data acquisition module mounted on the fixed part 120. This module acquires images of the electric vehicle's body and transmits the acquired data back to the data processing module. The data processing module uses big data to analyze the acquired images, confirms the location of the charging port, and adjusts the height of the charging gun 200 via a drive system to align it with the charging port. Finally, the drive system inserts the charging gun 200 into the electric vehicle's charging port to complete the charging process.
