Description

Technical Field

[0002] With the rapid development of the electric vehicle market, the demand for efficient and reliable charging solutions has also increased. At present, the connection of charging guns in most charging stations relies on manual operation, which not only reduces the charging efficiency, but also increases the inconvenience and safety hazards of operation. At the same time, a wireless charging mode has appeared on the market, in which a charger is installed on the ground of the parking space, and a receiver is also installed on the chassis of the electric vehicle. When the electric vehicle is parked in the parking space, the charger is triggered and transmits energy to the receiver through electromagnetic induction, achieving a wireless charging effect.

[0036] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0037] The advantage of the current wireless charging mode for electric vehicles is that it is free from manual operation and does not require the charging gun to be aimed at the charging port, thus saving the charging process. However, in actual applications, it is found that due to the lack of management and guidance in the parking lot, many gasoline vehicles or electric vehicles without charging needs will occupy the parking space, resulting in electric vehicles with wireless charging function being unable to use the parking space for charging, resulting in a waste of wireless charging parking spaces. Moreover, during the wireless charging process, the distance between the charger and the receiver will greatly affect the charging effect, and the different chassis heights of different cars will affect the actual charging efficiency, making the charging time difficult to estimate.

[0038] In this regard, the present application proposes an electric vehicle ground lock charging device and a working method thereof, which uses a camera 500 to identify vehicle information to determine whether it is an electric vehicle suitable for this parking space, and then decides whether to lower the warning sign 230 to allow the vehicle to enter, thereby avoiding other vehicles occupying this parking space; the charging plate 320 can be raised and lowered by a lifting mechanism 310, thereby adapting to vehicles with different chassis heights and maintaining consistency in charging efficiency.

[0039] Reference Figure 1 The electric vehicle ground lock charging device in the embodiment of the first aspect of the present application includes a base 100, a warning component 200, a charging component 300, a shell component 400 and a camera 500. Among them, the base 100 is the main structure of the electric vehicle ground lock charging device, which is fixedly installed on the ground and provides support for other components of the electric vehicle ground lock charging device. The warning component 200 is used to inform each car owner whether the parking space is open, and prevent other vehicles that are not suitable for this parking space from entering. The charging component 300 is used to charge the electric vehicle. The shell component 400 is used to protect the charging component 300 when the electric vehicle ground lock charging device is not enabled. The camera 500 is used to identify the incoming vehicle by image, so as to determine whether to turn off the warning component 200 to release it.

[0040] Specifically, the warning component 200 includes a flip motor 210, a rocker arm 220 and a warning sign 230. The flip motor 210 is installed on the base 100, and the two ends of the rocker arm 220 are respectively connected to the output shaft of the flip motor 210 and the warning sign 230. The warning sign 230 can be flipped by the drive of the flip motor 210. Corresponding warning patterns and slogans are set on the warning sign 230. When the warning sign 230 is driven by the flip motor 210 to flip out, the driver can see the warning content on the warning sign 230, understand the applicable vehicle type of the current parking space, and know that the parking space is in a closed state. Figure 2 When the warning sign 230 is driven by the flip motor 210 and lowered, the driver can drive the vehicle over the electric vehicle ground lock charging device, so that the device is located at the bottom of the vehicle and is ready for wireless charging.

[0041] The charging assembly 300 includes a lifting mechanism 310 and a charging plate 320. The two ends of the lifting mechanism 310 are respectively connected to the base 100 and the charging plate 320. The lifting mechanism 310 is used to drive the charging plate 320 to rise and fall. Thus, when the vehicle is parked, the lifting mechanism 310 can drive the charging plate 320 to rise to be sufficiently close to the vehicle chassis, thereby improving the efficiency and effect of wireless charging. In order to maintain a consistent charging effect, a distance sensor can also be provided on the lifting mechanism 310 to detect the distance between the charging plate 320 and the vehicle chassis. When the distance between the two reaches the set rated threshold, the lifting mechanism 310 stops further lifting.

[0042] The shell assembly 400 includes a cover plate 410 and a driving member 420. The cover plate 410 is movably connected to the base 100. The driving member 420 drives the cover plate 410 to move. The cover plate 410 can cover the charging plate 320, thereby covering and protecting the charging plate 320 when not in use.

[0043] The camera 500 is installed on the cover plate 410 , and the camera 500 is used for image recognition of information of parked vehicles.

[0044] The movable connection between the cover plate 410 and the base 100 may be a sliding connection or a flip connection, and the driving member 420 drives the cover plate 410 to move. In this embodiment, the cover plate 410 is specifically connected in a sliding manner. Figure 3 The base 100 is provided with a slide rail 110, and the cover 410 is slidably connected to the base 100 through the slide rail 110. The driving member 420 is specifically an electric roller, which is installed at the bottom of the cover 410 and contacts the ground. When the electric roller rolls, it can drive the cover 410 to slide with the ground as the fulcrum, so as to complete the opening or closing of the cover 410.

[0045] Furthermore, there are two cover plates 410, and the two cover plates 410 are separated from each other to expose the charging plate 320; Figure 3 and Figure 4 The two cover plates 410 can be assembled together to cover the charging plate 320.

[0046] Furthermore, a limit member 111 is installed at the end of the slide rail 110, and the projection area of ​​the limit member 111 along the slide rail direction is larger than the cross-sectional area of ​​the slide rail 110, so that when the cover plate 410 moves to the end of the slide rail 110, it will be restricted by the limit member 111 and cannot continue to slide, which is used to prevent the cover plate 410 from detaching from the slide rail 110.

[0047] Furthermore, the cover plate 410 is provided with a groove 411 , and the camera 500 is accommodated in the groove 411 , so that the camera 500 is protected by the groove 411 to prevent external force from directly impacting the camera 500 and causing damage to the camera 500 .

[0048] Furthermore, the housing assembly 400 further includes a rotating motor, which is mounted on the cover plate 410, and the output shaft of the rotating motor is connected to the camera 500 to drive the camera 500 to rotate. On the one hand, the pitch angle of the camera 500 can be changed by rotating the motor, so that it can be better oriented toward the vehicle to be detected; on the other hand, when the electric vehicle ground lock charging device is not in use, the camera 500 can be rotated 180 degrees to make the lens face the inside of the groove 411, avoiding external force directly impacting the lens or sewage contamination, thereby extending the service life of the camera 500.

[0049] Furthermore, the lifting mechanism 310 is specifically a worm gear mechanism, and the charging component 300 also includes a lifting motor, and the output shaft of the lifting motor is connected to the worm gear mechanism, thereby driving the worm gear mechanism to operate and drive the charging plate 320 to lift and lower.

[0050] Furthermore, the electric vehicle ground lock charging device further includes a water level sensor 600 and a temperature sensor 700, both of which are connected to the charging plate 320. The water level sensor 600 is used to detect whether there is water inundation and flooding the charging plate 320. When the water level is detected to be too high, the electric vehicle ground lock charging device is powered off in time to prevent leakage; the temperature sensor 700 is used to detect the working temperature of the charging plate 320. When the working temperature of the charging plate 320 is abnormal, the electric vehicle ground lock charging device can be powered off in time and the maintenance personnel can be notified for maintenance.

[0051] A working method for the electric vehicle ground lock charging device in an embodiment of the second aspect of the present invention comprises the following steps:

[0052] S100. The camera 500 identifies the incoming vehicle information and confirms whether it is a suitable vehicle for the parking space through the backend data center;

[0053] S200. After the backend data center determines that the vehicle is suitable, the flip motor 210 drives the warning sign 230 to be lowered, and the vehicle enters the parking space and parks;

[0054] S300.Reference Figure 1 and Figure 2 , the cover plate 410 is opened under the driving of the driving member 420 to expose the charging plate 320;

[0055] S400. The lifting mechanism 310 drives the charging plate 320 to rise until the distance between the charging plate 320 and the vehicle chassis reaches the rated threshold, and charging begins;

[0056] S500. After charging is completed, the lifting mechanism 310 drives the charging plate 320 to descend, and the cover plate 410 is closed and covers the charging plate 320 under the drive of the driving member 420;

[0057] S600. The vehicle leaves the parking space, refer to Figure 3 and Figure 4 , the flip motor 210 drives the warning sign 230 to flip out and wait for the next charging work.

[0058] The above is a specific description of the preferred implementation methods of the present application, but the invention is not limited to the embodiments.
