[0003] In recent years, due to the gradual transformation of China's automobile industry towards new energy vehicles, the utilization rate of electric vehicles has been increasing. However, if an electric vehicle is parked in a lifting and traversing parking equipment, its charging problem must be solved. Currently, the lifting and traversing parking equipment generally has multiple layers. After the automobile enters the lifting and traversing parking equipment, it drives onto the car-carrying plate on the entrance layer. After the driver leaves, the automobile is lifted and traversed with the car-carrying plate to a suitable area within the parking equipment. In order to charge an electric vehicle parked in the lifting and traversing parking equipment, in the existing charging methods, the electric vehicles parked on the car-carrying trays are of various types. When directly inserting the charging gun into the electric vehicle, it is inevitable that the charging gun cable needs to cross the electric vehicle for charging.

Moreover, most of the existing charging gun seats are set on the ground. When the driver needs to charge or end the charging of the electric vehicle, they need to reach over the car-carrying tray and the vehicle to pick up and place the charging gun, which has certain potential safety hazards.

[0036] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0037] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0038] Embodiment 1

[0039] The first embodiment of the present invention relates to a charging device. For details, please refer to Figure 1, including a vehicle-carrying tray 101, a charging gun 201, a charging gun cable 301, a rocker 401, a swing arm 501, and a charging pile 601; one end of the rocker 401 is vertically and fixedly installed at the edge position of the vehicle-carrying tray 101; the swing arm 501 is vertically connected to the rocker 401 and can rotate horizontally relative to the ground; one end of the charging gun cable 301 is electrically connected to the charging gun 201 through the swing arm 501 and the rocker 401, and the other end is electrically connected to the charging pile 601.

[0040] In this embodiment, two charging gun sockets 701 are further included. The charging gun sockets 701 are respectively arranged on both sides of the vehicle-carrying tray 101 and close to the charging socket of the vehicle, and are used for placing the gun head of the charging gun 201. The jacks of the charging sockets 701 face upward for the gun head of the charging gun 201 to be vertically inserted.

[0041] Specifically, the electric vehicles parked on the vehicle-carrying tray 101 are of various types. If the charging gun 201 is directly inserted into the electric vehicle, it is inevitable that the required charging gun cable 301 is relatively long, and the charging gun cable 301 needs to cross the electric vehicle. Due to the long charging gun cable 301, during the moving process, the charging gun cable 301 is likely to be entangled with other charging gun cables 301 or other devices, ultimately causing a charging failure. Moreover, most existing charging gun seats are arranged on the ground or directly behind the electric vehicle during charging. When the driver needs to charge or end the charging of the electric vehicle, he / she needs to cross over the vehicle-carrying tray or the electric vehicle to pick up and place the charging gun 201, which has certain safety hazards. By respectively arranging the charging gun sockets 701 on both sides of the vehicle-carrying tray 101 and close to the charging socket of the vehicle, all the operations required by the driver during charging can be completed on the side of the vehicle-carrying tray 101, without the driver having to cross between the ground and the vehicle-carrying tray 101, nor having to detour to the rear of the charging vehicle after parking for operation. In this embodiment, when the charging interface of the electric vehicle is on the left side, the driver can swing the swing arm 501 to the left before parking, and then drive the electric vehicle onto the vehicle-carrying tray. When the charging interface of the electric vehicle is on the right side, the driver can swing the swing arm 501 to the right before parking, and then drive the electric vehicle onto the vehicle-carrying tray, and then use the charging gun 201 close to the charging socket of the vehicle to charge the electric vehicle. The charging gun cable is relatively short and on the same side, making the charging gun cable safer. At the same time, it is convenient for the driver to insert the gun head of the charging gun 201 into the charging socket 701 after charging. The movable charging gun cable 301 between the swing arm 501 and the charging socket 701 is short. When the gun head of the charging gun 201 is inserted into the charging socket 701, it also effectively prevents the charging gun 201 and the charging gun cable 301 from extending beyond the vehicle-carrying tray 101.

[0042] In this embodiment, it further includes a limiting device 801. There are two limiting devices 801, which are respectively installed at the edge positions of the car-carrying tray 101 and on both sides of the rocker 401, and are used to limit the rocker arm 501 from exceeding the left or right position of the car-carrying tray 101; the charging gun 201 is shaken to the side of the charging socket of the required charging vehicle in advance through the rocker arm 501, and the gun head of the charging gun 201 is inserted into the charging socket 701.

[0043] In this embodiment, the charging device is applied to a lift and transfer vertical warehouse, and includes a transverse drag chain 901 and a first drag chain support device 1001; one end of the transverse drag chain 901 is connected to the first drag chain support device 1001, and the other end is connected to the car-carrying tray 101; the charging gun 201 is connected to the charging pile 601 through the charging gun line 301 passing through the transverse drag chain 901; the car-carrying tray 101 can move transversely, and the installation direction of the first drag chain support device 1001 is consistent with the transverse movement direction of the car-carrying tray 101.

[0044] It should be noted that when an electric vehicle needs to be parked in a first-floor parking space and charged, the driver can shake the rocker arm 501 to the side of the charging port of the electric vehicle before parking, and then park the electric vehicle on the car-carrying tray 101. After the driver inserts the charging gun 201 on the car-carrying tray 101 into the electric vehicle, the parking and charging process is completed. When it is necessary to pick up the vehicle, the driver pulls out the charging gun 201 inserted into the electric vehicle and inserts the charging gun 201 into the charging gun socket 701 to complete the vehicle pickup. The car-carrying tray 101 also includes a transverse movement motor. When the car-carrying tray on the first floor blocks the rise or fall of the car-carrying trays on the upper floors, the car-carrying tray is also provided with a transverse movement motor to transversely move the entire car-carrying tray, and the car-carrying trays on the same floor of other first floors are transversely moved as a whole. During the transverse movement, the electric vehicle remains in the charging state all the time.

[0045] During the transverse movement, the transverse drag chain 901 is adopted, which can not only meet the flexible movement of the cable, but also control the movement track, thereby reducing the hidden dangers and disadvantages that the movement track of the cable in the existing technical solution is not restricted, resulting in the garage alarm stopping operation. Moreover, the cable layout is convenient, the occupied space is small, and the electric vehicle remains in the charging state during the transverse movement, improving the charging efficiency.

[0046] Embodiment Two

[0047] In this embodiment, as Figure 2As shown, the charging device is applied to a lift and transfer automated storage and retrieval system, and includes a vertical drag chain 1101 and a second drag chain support device 1002. One end of the vertical drag chain 1101 is connected to the second drag chain support device 1002, and the other end is connected to the car tray 102. The charging gun 202 is connected to the charging pile 602 through the charging gun cable 302 passing through the vertical drag chain 1101. The car tray 102 can move up and down, and the installation direction of the second drag chain support device 1002 is the same as the up and down direction of the car tray 102.

[0048] Wherein, a lifting motor is further arranged on the car tray 102 to lift the car tray 102 as a whole.

[0049] It should be noted that in this embodiment, it corresponds to a two - layer parking garage. When an electric vehicle needs to be charged and parked on the upper layer, the parking space on the first floor moves horizontally to make way for the parking position. The car tray 102 of the upper lifting device on the upper - layer parking space descends to the parking position on the first floor. The driver shakes the rocker arm 502 to the side of the charging port of the electric vehicle before parking the vehicle on the car tray, then parks the electric vehicle on the car tray 102, plugs the charging gun 202 on the car tray 102 into the charging port of the electric vehicle. Finally, after the car tray 102 rises completely, it stops on the upper - layer parking space. When picking up the vehicle, the car tray 102 descends to the first floor for the driver to pick up the vehicle. After the car tray 102 descends to the first floor, the driver pulls out the charging gun 202 plugged into the electric vehicle, inserts the charging gun 202 into the charging gun socket 702, and drives out of the car tray 102 to complete the vehicle - picking - up process.

[0050] During the vertical lifting process, the vertical drag chain 1101 is adopted, which can not only meet the flexible movement of the cable but also control the movement trajectory, thus reducing the hidden dangers and disadvantages that the movement trajectory of the cable in the existing technical solutions is not restricted, resulting in the alarm and stop of the garage operation. Moreover, the cable layout is convenient, occupies little space, and the electric vehicle remains in the charging state during the lifting process, improving the charging efficiency.

[0051] Embodiment 3: In this embodiment, the charging device is applied to a lift and transfer automated storage and retrieval system, as Figure 3As shown in the figure, it includes a transverse drag chain 902, a vertical drag chain 1102, a third drag chain support device 1003, and a first transverse frame 1201; one end of the transverse drag chain 902 is connected to the third drag chain support device 1003, and the other end is connected to the first transverse frame 1201; the car carrier tray 103 can move transversely, and the setting direction of the third drag chain support device 1003 is the same as the transverse movement direction of the car carrier tray 103; one end of the vertical drag chain 1102 is connected to the first transverse frame 1201, and the other end is connected to the car carrier tray 103; the charging gun 203 is connected to the charging pile 603 through the charging gun cable 303 passing through the vertical drag chain 1102 and the transverse drag chain 902; when the car carrier tray 103 moves up and down, the vertical drag chain 1102 is rolled out and retracted along with the car carrier tray 103.

[0052] It should be noted that: in this embodiment, it corresponds to a multi-layer parking garage. When an electric vehicle needs to be charged and parked on the upper layer, the driver rocks the rocker arm 503 to the side of the charging port of the electric vehicle before parking on the car carrier tray, then parks the electric vehicle on the car carrier tray 103, and inserts the charging gun 203 on the car carrier tray 103 into the charging port of the electric vehicle. After the car carrier tray rises, the car carrier tray 103 and the first transverse frame 1201 are engaged and parked in the upper layer parking space; when the car carrier tray on the second layer blocks the rise or fall of the car carrier tray on the upper layer parking space, the car carrier tray 103 is transversely moved integrally with the car carrier tray 103 and the first transverse frame 1201 through a transverse motor, and during the transverse movement, the electric vehicle always remains in a charging state. When picking up the car, the car carrier tray 103 descends to the first floor for the driver to pick up the car. After the car carrier tray 103 descends to the first floor, the driver pulls out the charging gun 203 inserted into the electric vehicle, inserts the charging gun 203 into the charging gun socket 703, and drives out of the car carrier tray 103 to complete the car pick-up.

[0053] During the vertical lifting and transverse movement, the vertical drag chain 1102 and the transverse drag chain 902 are used, which can not only meet the flexible movement of the cable, but also control the movement trajectory, thus reducing the potential hazards and disadvantages that the movement trajectory of the charging gun cable in the existing technical solutions is not restricted, resulting in the garage alarm stopping operation. Moreover, the charging gun cable is conveniently arranged, occupies little space, and the electric vehicle always remains in a charging state during the lifting and transverse movement, improving the charging efficiency.

[0054] Among them, the cables of the transverse motor and the lifting motor are respectively arranged in the transverse drag chain 902 and the vertical drag chain 1102. Setting the cables of the motor in the drag chain makes the cables of the motor safe and not easily damaged. At the same time, it also makes the overall charging device of the stereoscopic garage operate more safely.

[0055] Embodiment 4

[0056] In this embodiment, the charging device is applied to a multi-layer automated storage and retrieval system (AS / RS). As Figure 4 shown, it further includes a first conductive device 13, a second conductive device 14, and a second transverse movement frame 1202. The first conductive device 13 is disposed on the side of the carrier pallet 104. The first conductive device 13 is connected to the charging gun 204 through a charging gun cable 304. A channel for accommodating the charging gun cable 304 is provided inside the carrier pallet 104. The second conductive device 14 is disposed on the second transverse movement frame 1202 and is electrically connected to the charging pile 604. The first conductive device 13 is connected to the second conductive device 14 to electrically connect the charging gun 204 to the charging pile 604.

[0057] Wherein, the first conductive device 13 includes: a support assembly, an elastic buffer assembly, and a conductor. The support assembly is disposed on the carrier pallet and is used to support the conductor through the elastic buffer assembly. The elastic buffer assembly is respectively connected to the conductor and the support assembly and is used to finely adjust the relative position of the conductor. The conductor is electrically connected to the charging gun 204 and is used to be electrically connected to the second conductive device 14 when charging an electric vehicle parked on the carrier pallet 104.

[0058] It should be noted that the first conductive device 13 adopts flexible connection. When the carrier pallet 104 rises and combines with the second transverse movement frame 1202, flexible connection is adopted, which makes it easier for the conductors to come into contact with each other, has a better error tolerance rate, is in an elastically abutted state, has a closer contact, prevents situations such as poor contact and electric leakage, and enhances the safety of charging.

[0059] In this embodiment, as Figure 5 shown, it further includes a transverse movement drag chain 903 and a fourth drag chain support device 1004. One end of the transverse movement drag chain 903 is connected to the fourth drag chain support device 1004, and the other end is connected to the second transverse movement frame 1202. The carrier pallet can move transversely with the second transverse movement frame 1202. The setting direction of the fourth drag chain support device 1004 is the same as the transverse movement direction of the second transverse movement frame 1202. The charging gun 204 is connected to the charging pile 604 through the charging gun cable 304 passing through the transverse movement drag chain 903. When the carrier pallet 104 moves transversely, the transverse movement drag chain 903 is wound and unwound with the second transverse movement frame 1202.

[0060] Specifically, in this embodiment, it corresponds to a multi-layer parking garage. When an electric vehicle needs to be charged and parked on the upper layer, the driver rocks the rocker arm 504 to the side of the charging port of the electric vehicle before parking the vehicle on the car-carrying tray 104. Then, the electric vehicle is parked on the car-carrying tray 104, and the charging gun 204 on the car-carrying tray 104 is plugged into the charging port of the electric vehicle. After the car-carrying tray 104 rises completely, the car-carrying tray 104 fits with the second transverse movement frame 1202, and the first conductive device 13 is electrically connected to the second conductive device 14 and stops at the middle-layer parking space. When the car-carrying tray on the middle-layer parking space blocks the rise or fall of the car-carrying tray on the upper-layer parking space, the car-carrying tray 104 is transversely moved integrally with the second transverse movement frame 1202 by a transverse movement motor, and during the transverse movement, the electric vehicle remains in the charging state. When picking up the vehicle, the car-carrying tray 104 is separated from the second transverse movement frame 1202, the first conductive device 13 is disconnected from the second conductive device 14, and the car-carrying tray 104 descends to the first floor for the driver to pick up the vehicle. After the car-carrying tray 104 descends to the first floor, the driver pulls out the charging gun 204 plugged into the electric vehicle, inserts the charging gun 204 into the charging gun socket 704, and drives out of the car-carrying tray 104 to complete the vehicle pick-up.

[0061] In this embodiment, a two-dimensional code is further included, and the two-dimensional code is disposed on the charging gun base or the car-carrying tray. Each charging pile 604 is matched with a two-dimensional code, and the charging pile 604 and the two-dimensional code are in one-to-one correspondence. The control platform can wirelessly receive any two-dimensional code scanned by the intelligent mobile terminal and send a charging instruction to the charging pile 604 corresponding to the two-dimensional code scanned by the intelligent mobile terminal through the centralized controller.

[0062] Each car-carrying tray 104 is matched with a two-dimensional code, and the car-carrying tray 104 and the two-dimensional code are in one-to-one correspondence. After the user parks the vehicle on the car-carrying tray 104, the user can scan the two-dimensional code disposed on the car-carrying tray 104 through an intelligent mobile terminal such as a smart phone and send the two-dimensional code to the cloud charging control platform. After receiving the two-dimensional code, the cloud charging control platform can determine which charging pile the user needs for charging in combination with the position that the car-carrying tray 104 is about to reach, and thus send a charging instruction to this charging pile through the centralized controller to make it charge.

[0063] It should be noted that when the charging device proposed in this embodiment is applied to an intelligent parking garage, when the driver parks the vehicle in front of the carrier tray, he / she shakes the rocker arm 504 to the side of the charging port of the electric vehicle, then parks the electric vehicle on the carrier tray 104 of the first-floor parking space, and plugs the charging gun 204 on the carrier tray 104 into the charging port of the electric vehicle. By scanning the QR code on the carrier tray 104 or the charging gun socket 704, the system selects the charging position, moves the carrier tray 104 to the selected charging position, and the second conductive device 14 arranged at the charging position is electrically connected to the first conductive device 13, thus charging the electric vehicle. When picking up the vehicle, the system controls the carrier tray 104 to leave the selected charging position, the first conductive device 13 is separated from the second conductive device 14, the carrier tray 104 returns to the first-floor parking space, the driver pulls out the charging gun 204 plugged on the electric vehicle, and inserts the charging gun 204 into the charging gun socket 704 to complete the vehicle pick-up. In this embodiment, the specific form of the first-floor parking space is not limited.

[0064] When the charging device proposed in this embodiment is applied to a lifting and traversing three-dimensional garage, when the electric vehicle needs to be charged and parked on the upper layer, the first-floor parking space traverses to make way for the parking position, and the carrier tray 104 of the upper lifting and traversing device on the upper layer descends to the first-floor parking position. When the driver parks the vehicle in front of the carrier tray, he / she shakes the rocker arm 504 to the side of the charging port of the electric vehicle, then parks the electric vehicle on the carrier tray 104 of the first-floor parking space, and plugs the charging gun 204 on the carrier tray 104 into the charging port of the electric vehicle. After the carrier tray 104 rises completely, it stops at the charging position, and the second conductive device 14 is electrically connected to the first conductive device 13, thus charging the electric vehicle and parking it on the upper-layer parking space. When picking up the vehicle, the carrier tray 104 descends to the first floor for the driver to pick up the vehicle. When the carrier tray descends, the first conductive device 13 is separated from the second conductive device 14. After the carrier tray 104 descends to the first floor, the driver pulls out the charging gun 204 plugged on the electric vehicle, and inserts the charging gun 204 into the charging gun socket 704 to complete the vehicle pick-up. In this embodiment, the specific form of the first-floor parking space is not limited.
