[0022] In order to facilitate understanding by those skilled in the art, the present invention will be further described in detail below in conjunction with specific embodiments.

[0023] The utility model provides a charging cabin based on full-automatic charging, such as Figure 1 As shown, including:

[0024] A first automatic charging docking mechanism 10, used to plug into the first automatic charging docking mechanism 10 of the charging robot to obtain a DC charging power source;

[0025] A low voltage power supply module 20, used to provide power to the main control module 40 and the communication module;

[0026] The fast charging interface 30 is used to connect to the fast charging interface 30 of the charging terminal to provide a DC charging power supply for the charging terminal. The first automatic charging docking mechanism 10 and the fast charging interface 30 are connected through a power supply circuit.

[0027] The main control module 40 is connected to the power supply circuit;

[0028] The charging cabin does not have an AC-to-DC charging power module for charging the electric vehicle.

[0029] Specifically, in this embodiment, the charging cabin further includes a communication module, the communication module is connected to the main control module 40, and the communication module is used to communicate with the charging terminal and the server.

[0030] In this embodiment, the communication module of the charging cabin communicates with the charging terminal via a CAN bus.

[0031] In other embodiments, the communication module is wireless communication, and the communication module is one of Wifi, Bluetooth, and 5G modules, so that the wireless communication connection can be achieved via a Wifi, Bluetooth, or 5G wireless communication network.

[0032] In this embodiment, the charging cabin is arranged near the electric vehicle passage, for example, on a parking lot pillar near the parking lot electric vehicle passage, or near the wall of the parking lot electric vehicle passage, or is separately arranged next to the parking lot electric vehicle passage.

[0033] The location of the charging cabin can be flexibly set, so as to effectively utilize existing parking resources and reduce the construction process of charging facilities.

[0034] In this embodiment, the first automatic charging docking mechanism 10 of the charging cabin faces the electric vehicle channel, which facilitates the charging robot to move to the charging cabin for charging and docking. The charging robot does not need to move to the charging port of the electric vehicle to charge, thereby avoiding being limited by the surrounding environment of the electric vehicle parking location, which causes the charging robot to be unable to approach the electric vehicle and charge the electric vehicle.

[0035] In an embodiment, the charging robot outputs DC power to the charging cabin through the first automatic charging docking mechanism 10, and the charging cabin outputs DC power to the charging terminal through the fast charging interface 30, so that the charging cabin does not need to be set as an AC-to-DC charging power module for charging electric vehicles.

[0036] In the prior art, charging piles generally need to be directly connected to the power distribution room to provide a high-current charging power supply, but the power distribution room is AC, so each charging pile needs an AC-to-DC charging power module. The charging power modules currently applicable to charging piles are expensive, often reaching several thousand yuan each, resulting in the inability to reduce the cost of charging piles and the cost of deploying a large number of charging piles throughout the parking lot. In this embodiment, the charging cabin is directly provided with a DC charging power supply by the charging robot, which in turn supplies power to the electric vehicle. Therefore, the charging cabin of this embodiment does not need to be set as an AC-to-DC charging power module for charging electric vehicles. When a large number of charging terminals and the charging cabin need to be deployed throughout the parking lot, the cost will be greatly reduced compared to the charging pile solution of the prior art.

[0037] In this embodiment, the low voltage power supply module 20 is powered by an external 220V power grid, a battery or a generator.

[0038] In this embodiment, the low-voltage power supply module 20 also provides power to the charging terminal.

[0039] In this embodiment, the charging cabin also includes a display module for indicating the charging terminal display control status, charging abnormality control status, and charging robot arrival prompt status.

[0040] In this embodiment, the display module is an indicator light, and there is one indicator light with different colors. The different colors of the indicator light correspond to the display control status of the charging terminal, the abnormal charging control status, and the arrival prompt status of the charging robot.

[0041] In other embodiments, there are multiple indicator lights with different colors, and the different colors or combinations of different colors of the indicator lights correspond to indicating the charging terminal display control status, the charging abnormality control status, and the charging robot arrival prompt status.

[0042] In another embodiment, the display module is an LED display panel, and the LED display panel correspondingly indicates the charging terminal display control status, the charging abnormality control status, and the charging robot arrival prompt status.

[0043] The charging terminal display control status controls the color status of the charging terminal indicator light according to the connection status of the charging terminal; the charging abnormality control status controls the abnormal termination of the charging robot according to the status of the emergency stop switch of the charging terminal; the charging robot in-place prompt status feeds back the connection status of the charging robot according to the in-place signal status of the charging robot and the first automatic charging docking mechanism 10.

[0044] The utility model also provides a fully automatic charging system, such as Figure 1-2 As shown, it includes a charging terminal 100 and the above-mentioned charging cabin 200 based on fully automatic charging;

[0045] The charging terminal 100 includes a charging gun holder and a charging gun, wherein a charging gun holder has at least one charging gun 20;

[0046] A charging cabin 200, wherein the charging cabin 200 and the corresponding charging gun seat structure are separated but electrically connected, the charging cabin 200 is close to the electric vehicle passage, and the charging cabin 200 has a first automatic charging docking mechanism 10, which is used to be plugged into the automatic charging docking mechanism of the charging robot to obtain a DC charging power supply, wherein the charging cabin 200 also includes: a low-voltage power supply module 20, a fast charging interface 30, and a main control module 40, wherein the low-voltage power supply module 20 is used to provide power to the main control module 40 and the communication module; the fast charging interface 30 is used to be connected to the fast charging interface 30 of the charging terminal to provide a DC charging power supply to the charging terminal, the automatic charging docking mechanism and the fast charging interface 30 are connected through a power supply circuit, and the main control module 40 is connected to the communication module and the power supply circuit; the charging cabin does not have an AC-to-DC charging power module for charging electric vehicles;

[0047] A charging robot 300, wherein the charging robot 300 includes an energy storage system, a charging system, an automatic driving control system, and a second automatic charging docking mechanism, and the charging robot does not have a charging gun;

[0048] A charging robot mother cabin, wherein the charging robot mother cabin has a third automatic charging docking mechanism for charging the charging robot;

[0049] When the charging gun corresponding to the charging gun holder is inserted into the charging port of the electric vehicle, in response to the user's vehicle charging instruction, the first information of the corresponding electric vehicle and the second information of the corresponding charging gun are obtained; the third information of the charging cabin is obtained according to the second information of the charging gun; according to the first information of the electric vehicle and the third information of the charging cabin, a suitable charging robot is called to move to the corresponding charging cabin position, the charging robot and the charging cabin are docked for charging, and the electric vehicle is charged through the charging cabin and the corresponding charging gun.

[0050] Specifically, the charging gun holder and the charging cabin 200 in this embodiment are separately arranged, wherein the charging cabin 200 is arranged near the electric vehicle passage, for example, on a parking lot pillar 400 near the electric vehicle passage of the parking lot, or near the wall of the electric vehicle passage of the parking lot, or is separately arranged next to the electric vehicle passage of the parking lot, wherein the first automatic charging docking mechanism 10 of the charging cabin 200 faces the electric vehicle passage.

[0051] The position of the charging gun holder can be flexibly set. It can be set in the middle of multiple parking spaces so that one charging gun holder can serve multiple parking spaces. A charging gun holder can also be set next to a parking space for exclusive charging. The charging gun holder can be located on the wall, ground or parking lot column 400 inside the parking space, or on the parking lot column 400, wall or ground near the electric vehicle passage in the parking lot.

[0052] The charging gun holder and the charging cabin 200 of the present solution are separately arranged. Since the charging cabin 200 is arranged near the electric vehicle passage, it is convenient for the charging robot to move to the charging cabin 200 for charging and docking. The position of the charging gun holder can be flexibly set, and the charging robot does not need to move to the charging port of the electric vehicle to charge, thereby effectively utilizing existing parking lot resources and reducing the construction process of charging facilities.

[0053] In this embodiment, the charging gun seat is only electrically connected to the corresponding charging cabin, and is not directly electrically connected to the external power grid. The charging gun seat in this solution is generally only a few meters away from the corresponding charging cabin, at most a dozen meters, and only a dozen meters of wiring is needed, and the charging cabin is powered; in the prior art, the power supply of the charging pile needs to be connected from a distant distribution room to provide a large current for the charging gun to charge. When the parking lot is large, a large number of dedicated wires are required. Using this solution can save a lot of later wiring costs.

[0054] The charging piles in the prior art are generally directly connected to the power distribution room to provide a high-current charging power supply, but the power in the power distribution room is AC, so each charging pile needs an AC-to-DC charging power module. The charging power modules currently applicable to charging piles are expensive, often reaching several thousand yuan each, resulting in the inability to reduce the cost of charging piles and the cost of deploying a large number of charging piles in the entire parking lot. In this embodiment, since the charging gun holder is only electrically connected to the corresponding charging cabin and is powered by the charging cabin, and the charging cabin is also directly charged by DC by the charging robot, the charging gun holder and the corresponding charging cabin of this solution do not need a built-in AC-to-DC charging power module. When a large number of charging gun holders and charging cabins are deployed in the entire parking lot, the cost will be greatly reduced compared to the charging pile solution of the prior art.

[0055] In this embodiment, each charging gun holder has one or more charging guns. When there are multiple charging guns, only one charging gun can be powered at the same time. Since this solution uses a charging robot to charge electric vehicles, the power of the energy storage system carried by the charging robot itself is limited, so generally one charging robot charges one electric vehicle with one charging gun.

[0056] In other embodiments, when a charging gun holder corresponds to multiple parking spaces, and an electric vehicle in one parking space is being charged with a charging gun, other electric vehicles cannot be charged. The driver of the next electric vehicle can only insert the charging gun into the charging port of the next electric vehicle after the corresponding charging gun is completed and returned to the charging gun holder. During this process, the driver of the next electric vehicle either waits in place or looks for other free parking spaces where the corresponding charging gun is not occupied, but both waste extra time. When each charging gun holder has multiple charging guns, the driver of the next electric vehicle can directly insert the second charging gun into the charging port of the next electric vehicle. Although the charging gun cannot charge the electric vehicle immediately, the driver of the next electric vehicle can leave after inserting the charging gun. After the previous charging gun is fully charged, the driver can immediately switch to powering the second charging gun to charge the charging port of the next electric vehicle.

[0057] In this embodiment, the charging robot 300 includes an energy storage system, a charging system, an automatic driving control system, a vehicle base, and a second automatic charging docking mechanism, and the charging robot does not have a charging gun. The charging robot 300 has a second automatic charging docking mechanism, which can be docked with the first automatic charging docking mechanism 10 of the charging cabin for DC charging; the second automatic charging docking mechanism can also be docked with the third automatic charging docking mechanism of the charging robot mother cabin, which is used for the charging robot mother cabin to recharge the charging robot.

[0058] And because the charging robot of this solution docks the charging cabin and the charging robot mother cabin through the second automatic charging docking mechanism, no charging gun is needed, saving hardware costs. And because the charging robot does not have a charging gun, the driver of the electric car does not need to wait for the charging robot to reach the charging position to plug and unplug the gun as in the prior art. The driver of the electric car of this patent directly inserts the charging gun of the charging gun holder next to the parking space into the electric car, saving the driver's time. Compared with other prior arts that use automatic mechanical arms to complete the automatic plug and unplug of charging guns, this application can greatly reduce the cost of the charging robot.

[0059] In other embodiments, when the local power grid corresponding to the parking lot is out of power, a charging robot can also be used to provide emergency power to the local power grid through the charging robot mother cabin.

[0060] Finally, it should be noted that any modification or equivalent replacement of part or all of the technical features based on the device structure of the utility model and the technical solution of the described embodiment, which does not deviate from the essence of the corresponding technical solution of the utility model, belongs to the patent scope of the device structure of the utility model and the described implementation scheme.
