Description

Technical Field

[0001] The present invention relates to the field of electric vehicle charging, and specifically to an automatic parking and charging system. Background Art

[0002] Zero-emission and zero-pollution electric vehicles are the main means of transportation in the future. Nowadays, electric vehicles are developing rapidly and occupying an increasingly large share in the market. However, there are still many drawbacks in the related technologies and supporting facilities of electric vehicles. The most urgent technical problem to be solved is the charging endurance problem, which requires the establishment of more efficient and faster charging stations in areas such as roads and parking lots to ensure that the charging needs of a large number of electric vehicles can be met. In traditional parking lots, the number of charging stations is limited. When an electric vehicle is charging, it needs to park the vehicle at the corresponding charging position. However, when there is an electric vehicle charging at a charging position, other electric vehicles that need to charge can only use the charging station after the vehicle has completed charging and the owner has driven away. It can be seen that the traditional charging method is quite difficult, with low alternating efficiency and poor user experience. Although there is an automatic parking system on the market that can assist in coordinating the parking spaces in the entire parking lot, and this system can use an automatic driving transport vehicle to park the vehicle in an idle parking position, this automatic parking system cannot solve the problem of electric vehicle charging, and a large-scale transformation of the original parking lot is required before using this automatic parking system, resulting in a relatively large investment cost.

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] See Figures 1-13, the automatic parking and charging system involved in this embodiment includes

[0046] The first embodiment

[0047] A movable deck 400 for loading a target electric vehicle 500 (the electric vehicle to be charged); this movable deck 400 is a bracket capable of carrying the target electric vehicle 500, and when not in use for handling, the movable deck 400 is supported on the ground.

[0048] An automatic guided vehicle 300 that transports the target electric vehicle 500 to the charging position A through the movable deck 400; the automatic guided vehicle 300 travels along a set route issued by the control system, and this set route is a route customized according to the layout of the parking lot where it is located; in this embodiment, the automatic guided vehicle 300 is preferably an AGV cart, and this automatic guided vehicle 300 can be wirelessly communicatively connected to the control terminal to obtain various data or instructions and accept route updates and system upgrades at any time.

[0049] A charging connector, including a charging end connection device 100 electrically connected to the charging end of the target electric vehicle 500 and a power supply end connection device 200 electrically connected to the power supply end of the charging station B; the charging end connection device 100 is arranged on the movable deck 400 and moves with the movable deck 400; the power supply end connection device 200 is arranged on the charging station B; the charging end connection device 100 and the power supply end connection device 200 are respectively controlled by the control system; at the charging position A, the charging end connection device 100 and the power supply end connection device 200 are electrically connected to each other.

[0050] This automatic parking and charging system can effectively coordinate and arrange the parking space, greatly improving the utilization rate of the parking positions in the parking lot and making the parking more orderly. Whether it is upgrading a traditional parking lot to a semi-automatic or fully automatic parking lot, or building a brand-new fully automatic parking lot, this automatic parking and charging system is applicable and is the general trend. In addition, the target electric vehicle to be charged can be automatically transported to the charging position for charging by the automatic guided vehicle, and the target electric vehicle that has completed charging can be automatically transported back to the initial parking position by the automatic guided vehicle, enabling each electric vehicle to charge automatically and orderly, making full use of the charging station resources, and users do not need to wait in the vehicle and waste time. It can be seen that on the one hand, this system can solve the problem for electric vehicle users of not being able to find a charging position in the parking lot, and on the other hand, it can provide a better charging station management solution for the parking lot manager, making the existing charging stations more efficient and charging more electric vehicles in need.

[0051] Furthermore, a charging console 41 is provided on the movable deck 400. The charging console 41 is electrically connected to the target electric vehicle 500 and the charging end connection device 100 respectively, and the charging end connection device 100 is electrically connected to the target electric vehicle 500 through the charging console 41. Specifically, the charging console 41 is a device that can adapt to the charging interfaces of various electric vehicles. When the electric vehicle is parked on the movable deck 400, the user electrically connects the charging cable on the charging console 41 to the charging interface on the electric vehicle for charging. Related sensors are provided on the movable deck 400. When the sensors detect an electric vehicle on the movable deck 400 but the charging console 41 is not connected to the corresponding charging interface, the sensors feedback relevant signals to the control system, and the control system sends a prompt to the vehicle owner through relevant components. The power supply end connection device 200 is fixedly provided on one side of the charging station B. The charging station B is electrically connected to the power supply through the power supply seat B1, and the power supply end connection device 200 is electrically connected to the power supply seat B1.

[0052] In the above charging connector, the charging end connection device 100 includes a charging connector 13 electrically connected to the charging end of the target electric vehicle 500. The charging connector 13 is movably arranged relative to the movable deck 400. The power supply end connection device 200 includes a power supply connector 26 electrically connected to the power supply end of the charging station B (i.e., the power supply seat B1) and a correction push rod 24 for correcting the charging connector 13. The power supply connector 26 and the correction push rod 24 are respectively arranged to move longitudinally. When the correction push rod 24 moves longitudinally to touch the charging connector 13, the movable charging connector 13 can be automatically corrected, generally referring to that the charging connector 13 automatically swings to a set orientation under the action of the correction push rod 24 for later electrical connection with the power supply connector 26. The power supply connector 26 moves longitudinally to be electrically connected to the corrected charging connector 13.

[0053] Furthermore, a charging part 1302 electrically connected to the charging end of the target electric vehicle 500 is provided on the charging connector 13, and the charging part 1302 moves with the charging connector 13. A power supply part 2601 electrically connected to the power supply end of the charging station B is provided on the power supply connector 26, and the power supply part 2601 moves with the power supply connector 26. The charging part 1302 and the power supply part 2601 in this embodiment can be conductive metal parts such as conductive sheets. The power supply end connection device 200 further includes a deviation correction component for correcting the lateral position of the charging connector 13, so that the charging part 1302 corresponds to the power supply part 2601 by correcting the lateral position of the charging connector 13, to ensure that the power supply part 2601 moves longitudinally to be electrically connected to the charging part 1302 and ensure the electrical connection performance between them.

[0054] Further, the deviation rectifying assembly in this embodiment includes a first deviation rectifying member 27 and a second deviation rectifying member 27'. The first deviation rectifying member 27 and the second deviation rectifying member 27' are respectively arranged to move horizontally. Moreover, the first deviation rectifying member 27 and the second deviation rectifying member 27' move horizontally closer to or away from each other relatively; the charging connector 13 and the power supply connector 26 are respectively located between the first deviation rectifying member 27 and the second deviation rectifying member 27'. Among them, the power supply connector 26 is fixedly arranged at the exact center between the first and second deviation rectifying members, while the charging connector 13 can move freely horizontally; the first deviation rectifying member 27 and the second deviation rectifying member 27' move horizontally closer to each other relatively to clamp the charging connector 13, so that the charging connector 13 moves horizontally to the exact center between the two deviation rectifying members, thereby realizing horizontal position deviation rectification, so that the power supply part 2601 and the charging part 1302 are longitudinally corresponding.

[0055] Further, the power supply end connection device 200 further includes a power supply base body 21, a first longitudinal guide rail 22, a transverse guide rail bracket 23, a second longitudinal guide rail 25, a first longitudinal driving assembly for driving the transverse guide rail bracket 23 to move longitudinally on the first longitudinal guide rail 22, a second longitudinal driving assembly for driving the power supply connector 26 to move longitudinally on the second longitudinal guide rail 25, and a transverse driving assembly for driving the first deviation rectifying member 27 and the second deviation rectifying member 27' to move horizontally on the transverse guide rail bracket 23. Two first longitudinal guide rails 22 are arranged and are respectively fixedly arranged on both sides of the top of the power supply base body 21, and the first longitudinal guide rails 22 extend longitudinally; both ends of the transverse guide rail bracket 23 are respectively slidably supported on the tops of the two first longitudinal guide rails 22, and the transverse guide rail bracket 23 extends horizontally; the correction push rod 24, the second longitudinal guide rail 25, the first deviation rectifying member 27 and the second deviation rectifying member 27' are respectively arranged on the transverse guide rail bracket 23 and move longitudinally with the transverse guide rail bracket 23. Among them, the correction push rod 24 and the second longitudinal guide rail 25 are respectively fixedly arranged on the transverse guide rail bracket 23, the first deviation rectifying member 27 and the second deviation rectifying member 27' are respectively arranged to move horizontally on the transverse guide rail bracket 23, and the first deviation rectifying member 27 and the second deviation rectifying member 27' respectively extend longitudinally; the power supply connector 26 is longitudinally slidably arranged on the second longitudinal guide rail 25, and the power supply connector 26 and the second longitudinal guide rail 25 respectively extend longitudinally; the first longitudinal driving assembly is arranged between the transverse guide rail bracket 23 and the first longitudinal guide rail 22; the second longitudinal driving assembly is arranged between the power supply connector 26 and the second longitudinal guide rail 25; the transverse driving assembly is arranged between the two deviation rectifying members and the transverse guide rail bracket 23; specifically, the first longitudinal driving assembly, the second longitudinal driving assembly and the transverse driving assembly can respectively adopt existing driving methods, such as: screw-nut driving method, gear-rack driving method, sprocket-chain driving method, cylinder or oil cylinder driving method, etc.

[0056] Further, a charging end face 1301 extending horizontally is provided on the end face of the charging connector 13; a power supply end face 2401 extending horizontally is provided on the end face of the calibration push rod 24; the power supply end face 2401 moves with the calibration push rod 24 to abut against the charging end face 1301. Since the charging end face 1301 can move with the charging connector 13, the charging end face 1301 can be automatically calibrated to fit the power supply end face 2401, preparing for the subsequent electrical connection between the power supply connector 26 and the charging connector 13.

[0057] Further, a strip-shaped moving slot 1303 is formed inside the charging connector 13, and the top and bottom of the moving slot 1303 are respectively open; the charging end connection device 100 further includes a connector bracket 11 and a guide post 12 extending vertically; one end of the connector bracket 11 is connected to the movable deck 400, and the other end is fixedly connected to the top end of the guide post 12; the bottom end of the guide post 12 extends into the moving slot 1303 and is fixedly connected to the movable deck 400. The guide post 12 limits the movement of the charging connector 13, and the charging connector 13 swings, moves, or swings and moves relative to the guide post 12, so that the charging connector 13 can be automatically calibrated.

[0058] The specific operation of the automatic parking charging system is as follows:

[0059] 1. The user parks the electric vehicle to be charged on the movable deck 400, and the vehicle owner electrically connects the charging cable on the charging console 41 to the charging end of the electric vehicle (generally referring to the charging socket); the system marks the electric vehicle to be charged as the target electric vehicle 500.

[0060] 2. The control system issues a transportation instruction to the automatic guided vehicle 300. The automatic guided vehicle 300 walks along the route corresponding to the transportation instruction to the lower part of the corresponding target electric vehicle 500, and the automatic guided vehicle 300 jacks up the movable deck 400 carrying the target electric vehicle 500 and transports it to the charging position A corresponding to the charging station B along the route planned by the system.

[0061] 3. When each sensing module in the charging position A and / or the charging station B detects that the target electric vehicle arrives at the charging position A, the charging connector 13 in the charging end connection device 100 moves with the movable deck 400 to be parallel and close to the power supply connector 26 and the calibration push rod 24 in the power supply end connection device 200; the control system issues a power connection instruction to the power supply end connection device 200, and the power supply end connection device 200 executes the power connection instruction to connect the target electric vehicle to the power supply.

[0062] 4. After the charging end connection device 100 and the power supply end connection device 200 are electrically connected to each other, they feedback corresponding signals to the control system. After receiving the corresponding signals, the control system confirms that the two connection devices (100 and 200) are electrically connected to each other and there is a charging signal.

[0063] 5. The control system issues an instruction to the automatic guided vehicle 300 to control the automatic guided vehicle 300 to unload the movable deck 400 and leave;

[0064] 6. When the previous target electric vehicle 500 finishes charging, the control system issues an instruction to the automatic guided vehicle 300 to control the automatic guided vehicle 300 to transport the charged target electric vehicle 500 to the initial position through the corresponding movable deck 400;

[0065] 7. The control system issues another charging task to the same (the same automatic guided vehicle 300 as in item 6) or a different automatic guided vehicle 300 to control the automatic guided vehicle 300 to transport the next target electric vehicle 500 to the charging position A for charging; this system works in this cycle.

[0066] In item 3 above, the power supply end connection device 200 executes the power connection instruction as follows:

[0067] See Figure 6 and Figure 7 , the automatic guided vehicle 300 transports the target electric vehicle to the charging position A through the movable deck 400, and the charging connector 13 in the charging end connection device 100 is roughly parallel to the alignment push rod 24 in the power supply end connection device 200;

[0068] See Figure 8 and Figure 9 , the alignment push rod 24, the power supply connector 26, the first deviation correction component 27 and the second deviation correction component 27' move longitudinally respectively, wherein the power supply end face 2401 on the alignment push rod 24 presses parallel to the charging end face 1301 on the charging connector 13, and the charging connector 13 is automatically corrected, and the power supply end face 2401 and the charging end face 1301 are mutually attached;

[0069] See Figure 10 and Figure 11 , the first deviation correction component 27 and the second deviation correction component 27' move closer to each other laterally to clamp the charging connector 13. Since the first deviation correction component 27 and the second deviation correction component 27' move simultaneously and synchronously respectively, the charging connector 13 is effectively driven to move laterally to the central position, so that the power supply part 2601 and the charging part 1302 are longitudinally corresponding;

[0070] See Figure 12 and Figure 13 , the power supply connector 26 moves longitudinally again to effectively electrically connect the power supply part 2601 and the charging part 1302, electrically connect the power supply end connection device 200 and the charging end connection device 100, and further realize the charging connection of the target electric vehicle 500.

[0071] Second Embodiment

[0072] SeeFigures 14-21 , what is different between the automatic parking and charging system in this embodiment and the first embodiment is that: the deviation correction component includes an identification and positioning code 1304 provided on the charging connector 13 and a deviation correction camera module 28 for photographing and finding the identification and positioning code 1304; the identification and positioning code 1304 is preferably provided on the charging end face 1301 and above the charging part 1302, and the identification and positioning code 1304 is preferably a QRCode, etc.; the power supply connector 26 is arranged to move horizontally, the deviation correction camera module 28 moves horizontally with the power supply connector 26, and the height positions of the identification and positioning code 1304 and the deviation correction camera module 28 are close or the same; when the deviation correction camera module 28 moves horizontally with the power supply connector 26 to find the identification and positioning code 1304, the control system controls the power supply connector 26 to brake.

[0073] Furthermore, the power supply end connection device 200 further includes a first longitudinal guide rail 22, a transverse guide rail bracket 23, a second longitudinal guide rail 25, a first longitudinal drive component for driving the transverse guide rail bracket 23 to move longitudinally on the first longitudinal guide rail 22, a second longitudinal drive component for driving the power supply connector 26 to move longitudinally on the second longitudinal guide rail 25, and a transverse drive component for driving the second longitudinal guide rail 25 to move horizontally on the transverse guide rail bracket 23; the correction push rod 24 and the second longitudinal guide rail 25 are respectively arranged on the transverse guide rail bracket 23 and move longitudinally with the transverse guide rail bracket 23; the power supply connector 26 is arranged on the second longitudinal guide rail 25; the first longitudinal drive component is arranged between the transverse guide rail bracket 23 and the first longitudinal guide rail 22; the second longitudinal drive component is arranged between the power supply connector 26 and the second longitudinal guide rail 25; the transverse drive component is arranged between the second longitudinal guide rail 25 and the transverse guide rail bracket 23; the deviation correction camera module 28 is fixedly arranged on the power supply connector 26.

[0074] In this embodiment, the power supply end connection device 200 executes the power connection instruction as follows:

[0075] See Figure 14 and Figure 15 , the automatic guided vehicle 300 transports the target electric vehicle to the charging position A through the movable deck 400, and the charging connector 13 in the charging end connection device 100 is roughly parallel to the correction push rod 24 in the power supply end connection device 200;

[0076] See Figure 16 and Figure 17 , the correction push rod 24 and the power supply connector 26 move longitudinally respectively, wherein the power supply end face 2401 on the correction push rod 24 presses the charging end face 1301 on the charging connector 13 in parallel, the charging connector 13 is automatically corrected, and the power supply end face 2401 and the charging end face 1301 are mutually attached;

[0077] See Figure 18 andFigure 19 The power supply connector 26 and the deviation rectifying camera module 28 move horizontally simultaneously and synchronously to search for and identify the positioning code 1304. When the deviation rectifying camera module 28 finds the positioning code 1304, the control system controls the power supply connector 26 to stop moving. At this time, the power supply unit 2601 and the charging unit 1302 are longitudinally corresponding.

[0078] See Figure 20 and Figure 21 The power supply connector 26 moves longitudinally again to enable the effective electrical connection between the power supply unit 2601 and the charging unit 1302, and to electrically connect the power supply end connection device 200 and the charging end connection device 100, thereby achieving the charging connection of the target electric vehicle 500.
