Background

With the increase of electric vehicles, how to realize convenient charging becomes a focus of attention of all parties, and the currently commonly adopted charging mode of manual plugging and unplugging of users has some problems in the aspects of convenience, safety, adaptability and the like. On the other hand, with the development of automatic driving technology, there have been developed or developed a function of automatically driving a vehicle to a parking space and a function of automatically driving a vehicle from the parking space to a designated location where a user is located according to a user call; under the condition, if the user needs to charge in a manual plugging mode, the operation is inconvenient, and the user experience is greatly reduced.

Therefore, the automatic charging mode which is 'insensitive to the user' and replaces the manual plugging charging mode is gradually a necessary choice. However, there are still many problems with the existing automatic charging scheme:

1. the equipment cost is high, adaptability is low:

many solutions employ "self-propelled vehicles", such as chinese patent application "2015800688616 for charging stations and methods for automatically charging an electric energy accumulator in a vehicle"; because parking spaces in cities are short, open parking spaces in a plurality of districts are defined on grasslands, soil lands and the like, and the self-propelled trolley is difficult to realize the adaptation of all terrains; if the weather is severe such as rain and snow, the normal work is more likely to be impossible;

2. problems with cable connections:

in the process of realizing automatic charging connection, a section of power cable is necessarily involved to be movable or telescopic, and the length of the power cable is about 3-10 meters according to different design schemes; however, even with the cost increased by several times, it is difficult for mobile cables to achieve safety and service life comparable to fixedly laid cables, especially mobile cables that are in direct contact with the ground; if the cable is damaged in the long-term use process, potential safety hazards are buried in the operation of the charging system;

3. the problem of the position of a charging interface is as follows:

the conventional vehicle charging interface is generally positioned on the side surface of a vehicle head or a vehicle body, so that manual operation of a user is facilitated, and a certain distance is reserved from the ground; however, such a location creates certain difficulties for the connection process of the automatic charging, which generally increases the difficulty and complexity of the design.

In summary, how to design a stable, flexible and efficient automatic charging system becomes a problem to be solved.

It should be noted that the lifting mechanism and the telescopic moving mechanism may adopt many structural forms, which are described below by way of example.

For example, the lifting mechanism can adopt a structure of a screw rod, a nut and a stepping motor combination.

The telescopic moving mechanism can adopt the following structure: the device comprises a rotating shaft, a telescopic arm, a moving mechanism and a telescopic cable; the telescopic arm can be extended or shortened, the telescopic arm is fixedly arranged on the rotating shaft, a moving mechanism is arranged on the telescopic arm, the charging plug is arranged on the moving mechanism of the telescopic arm, and the telescopic arm can be driven by the moving mechanism to move back and forth along the length direction of the lower telescopic arm; the telescopic cable is connected with the charging plug and can extend or shorten in coordination with the change of the position of the charging plug; along with the rotation of the rotating shaft, the extension or the shortening of the telescopic arm and the position change of the charging plug driven by the moving mechanism; the position of the charging plug can cover a circular area which takes the rotating shaft as the center and takes the arm expansion of the telescopic arm as the radius.

The above structure can achieve the function, but the structure is relatively complicated; because vehicle chassis's height is limited, the utility model discloses a charging device's usable space is less, should adopt more succinct mechanical structure as far as possible. Therefore, the utility model discloses an important adoption is including the flexible moving mechanism of gyration main shaft 5 and horizontal drive mechanism 7, and the structural design is seen embodiment three in detail.

Specifically, as shown in fig. 1, electric cables are fixedly laid on and around the parking space, and a power supply is connected with the parking space charging device through the electric cables; and a communication cable can be laid synchronously, and the control system is connected with the charging device through the communication cable. The communication connection mode of the control system and each parking space charging device can also adopt a wireless communication mode to replace a communication cable. In addition, the control system arranged outside is used for executing part or all of the control functions of the parking space charging device, and a single control system used for executing part of the control functions can be arranged inside the parking space charging device.

In the case of the disordered charging, the parking destination needs to individually configure a charging power of about 7Kw for each electric vehicle, and as the proportion of the electric vehicle increases, the total power capacity of the parking destination cannot be supported. Meanwhile, the average daily driving mileage of the passenger vehicle is short, the average daily driving mileage of the passenger vehicle in China is about 50 kilometers, the equivalent daily supplementary electric quantity of the electric passenger vehicle is about 8-10Kwh, the effective parking time of the passenger vehicle at the parking destination is calculated as 8 hours, and under the condition of orderly charging, the electric power capacity increasing pressure when the parking destination is provided with a large number of charging devices is greatly relieved through time-sharing multiplexing of power, namely, the electric vehicle is only required to be provided with the charging power of about 1 Kw.

a parking space charging device comprises a base, a charging interface platform, a lifting mechanism, a telescopic moving mechanism, a positioning module, a charging plug and a control system; wherein:

the supporting platform 3 is installed on the lifting spindle 2 and serves as an installation foundation of the charging interface platform 4;

a rotary main shaft 5 and a horizontal driving mechanism 7 are arranged in the supporting platform 3, and the charging interface platform 4 is arranged on the horizontal driving mechanism 7 of the supporting platform 3; the rotary main shaft 5 is used for driving the charging interface platform 4 to perform rotary motion; the horizontal driving mechanism 7 is used for driving the charging interface platform 4 to horizontally stretch and move; specifically, the horizontal driving mechanism 7 can perform horizontal telescopic movement on the basis of the direction angle determined by the rotary motion of the rotary main shaft 5;

Further, the parking space charging device also comprises a protection plate 11 arranged at the top of the parking space charging device; when the parking space charging device is in a shrinkage and sinking state, the parking space charging device is wholly sealed in a pit which is lower than the surface of the parking space in the parking space through the protection plate 11, and the protection effect is achieved through the protection plate 11.

The parking space is provided with a parking space, and the vehicle and/or the driver and the passenger are/is provided with an information prompt device for prompting the information or/and interacting the information before the vehicle is parked in the parking space.

Further, still include winding mechanism 12, the power and charging plug 8 are connected respectively at the both ends of the cable in winding mechanism 12, and when flexible moving mechanism drove charging plug 8 and moved, winding mechanism 12 was used for receiving and releasing of cable to adapt to the distance change of winding mechanism 12 and charging plug 8.

The support mechanism 13 has a dynamically adjustable telescopic function, and can be brought into contact with and supported by the surface of the parking space at an appropriate timing, or be separated from the surface of the parking space.

The working process of the parking space charging device of the embodiment is shown in fig. 6-10.

As shown in fig. 6, the parking space charging device is in an initial shrinkage sinking state;

as shown in fig. 7, after the electric vehicle is parked in the parking space, the position of the parking space charging device is first raised as a whole by the fork-scissor mechanism; the raised height must be lower than the height of the vehicle chassis (about 120 mm and 150 mm), and the raised position can be adjusted according to different vehicle chassis heights, so that the charging interface platform 4 is properly close to the vehicle chassis;

as shown in fig. 8, the specific position of the vehicle-mounted charging interface is determined by the positioning module 9, in this example, the positioning module 9 employs two cameras installed in the charging interface platform 4, namely a first camera and a second camera; the first camera firstly works, the charging interface platform 4 is driven to rotate through the rotary main shaft 5, meanwhile, an image in front of the charging interface platform 4 is shot through the first camera, and the specific position of the vehicle-mounted charging interface is searched according to an optical signal sent by the vehicle-mounted charging interface; when the vehicle-mounted charging interface is positioned in the middle of the image shot by the first camera, the fact that the angle of the rotary main shaft 5 is aligned with the direction of the vehicle-mounted charging interface is shown;

it should be noted that, because the positions of the vehicle-mounted charging interfaces installed at the bottoms of the electric vehicles of different brands and models are different, the parking direction of the user is opposite; therefore, preferably, the parking space charging device is arranged in the middle of the parking space, and the rotary main shaft 5 can rotate 360 degrees or nearly 360 degrees to adapt to the situation that the position of the vehicle-mounted charging interface appears in different directions. This has the advantages of shortening the moving distance of the telescopic moving mechanism and improving the reliability of operation.

As shown in fig. 9, the horizontally telescopic fork shear structure is started to drive the charging interface platform 4 to move to the position of the vehicle-mounted charging interface until the charging interface platform 4 moves to the position below the vehicle-mounted charging interface; in the process, if the support mechanism 13 is required to assist in completing the movement of the charging interface platform 4, the support mechanism 13 is properly extended and forms a support with the ground, and meanwhile, a structure which is beneficial to the stable movement of the charging interface platform 4, such as a roller, is required to be arranged at the bottom of the support mechanism 13; if the support mechanism 13 is not needed to assist in completing the movement of the charging interface platform 4, the support mechanism 13 is contracted to keep a suspended state; after the charging interface platform 4 is moved into position, the supporting mechanism 13 usually needs to be extended properly and form a support with the ground, and the supporting mechanism 13 can be locked, so that the position of the charging interface platform 4 is fixed.

As shown in fig. 10, although the charging interface platform 4 has reached the position below the vehicle-mounted charging interface, the accuracy of the whole moving process is relatively low in consideration of cost; at this time, the position adjusting mechanism 6 is started to finely adjust the position of the charging plug 8; the main body of the position adjusting mechanism 6 is a transverse sliding groove, the charging plug 8 can move in the sliding groove so as to be accurately butted with a vehicle-mounted charging interface, and in the process, a second camera can shoot upwards to perform auxiliary positioning; in addition, a combined positioning mechanism with a plurality of groups of photoelectric switches with lower cost can also be adopted. Of course, the position adjusting mechanism 6 may also adopt other structural forms having a position adjusting function.

It should be noted that the low-cost structures such as the low-precision camera and the photoelectric switch are adopted on the premise that no strict time limit condition is provided for the automatic charging connection process in practical application, and because the invention is mainly used for the slow charging scene, the automatic charging connection completion within 1 minute or even 10 minutes is acceptable.

Finally, after charging is completed, the parking space charging device can be completely contracted and completely hidden in the surface of the parking space by adopting the reverse operation of the operation.

Further, when the parking position is in an idle state, if the control system receives a locking request for the parking position, the lifting mechanism is started to lift the charging device, and the parking space is locked.

Further, the parking space system further comprises an information prompting device, and when the parking space is locked, information prompting is carried out on a vehicle or a user who wants to use the parking space through the information prompting device.

Specifically, as shown in fig. 4, when the parking space is locked, the raised height of the parking space charging device is H2, the height of the vehicle chassis is H1, and H2> H1; the information prompt device is arranged on the top or the front side surface of the parking space charging device so as to prompt information.

Further, when a vehicle in a non-charging state is parked at the parking position, if the vehicle in the non-charging state is ready to be accommodated at the position, the control system sends a prompt message to a manager, and the manager intervenes.

The utility model discloses the part that does not relate to is the same with prior art or can adopt prior art to realize.
