[0092] The embodiment of the present application discloses an intelligent energy storage DC mobile charging robot.

[0093] See also Figure 1 , an embodiment of the intelligent energy storage DC mobile charging robot provided in the embodiments of the present application includes:

[0094] Aerial carrier 200 and charging robot device 100;

[0095] The charging robot device 100 includes a device carrier 101 , a charging pile gun 103 and a charging drive device 102 .

[0096] The device carrier 101 is movably mounted on the aerial carrier 200 .

[0097] The charging drive device 102 is installed on the device carrier 101 and connected to the charging pile gun 103, and is used to drive the charging pile gun 103 to move to a preset charging preparation position or to a position docking with the charging port of the object to be charged. When the charging pile gun 103 reaches the preset charging preparation position, the user can operate and insert the charging pile gun 103 into the charging port of the car to be charged. This method is a semi-automatic method.

[0099] 1. The charging robot device 100 is suspended on the aerial carrier 200 without occupying ground area.

[0100] 2. The charging robot device 100 is mobile and can be moved to a designated location as needed. Moreover, the number of devices can be increased or decreased as needed, thereby improving the utilization rate of the charging robot device 100 and reducing operating costs.

[0101] 3. The charging pile gun 103 in the charging robot device 100 adopts the charging drive device 102 for position control, and can be moved to a preset charging preparation position or to a position docking with the charging port of the object to be charged, which is more flexible and convenient to use.

[0102] The above is the first embodiment of the intelligent energy storage DC mobile charging robot provided in the embodiment of the present application. The following is the second embodiment of the intelligent energy storage DC mobile charging robot provided in the embodiment of the present application. For details, please refer to Figures 1 to 6 .

[0103] Based on the solution of the above embodiment 1:

[0104] Further, for the design of the aerial carrier 200, Figure 1 As shown, it may include a guide rail 201 and at least two fixing seats 202 .

[0105] At least two ends of the top of the guide rail 201 are respectively fixed with a fixing seat 202 , and the device carrier 101 is movably mounted on the guide rail 201 .

[0106] One guide rail 201 may correspond to a row of 3-5 parking spaces, and multiple charging robot devices 100 may be configured on one guide rail 201 to meet the need for simultaneous use.

[0107] Furthermore, if Figure 2 As shown, in order to better achieve fixed connection, the guide rail 201 is provided with a first clamping portion 21, and the fixing seat 202 is provided with a second clamping portion 22 that is clamped and matched with the first clamping portion 21; the first clamping portion 21 and the second clamping portion 22 are in a hook structure, which is not limited.

[0108] The fixing seat 202 is also provided with a connecting fixing lug 23, and the fixing lug 23 is provided with a fixing connector 24 inserted therein. The fixing connector 24 can be a fixing member such as a bolt to facilitate the fixing connection.

[0109] Furthermore, in order to achieve automation and improve ease of use, the charging robot device 100 also includes a carrier driving device 300 , which is installed on the device carrier 101 and connected to the guide rail 201 , and is used to drive the device carrier 101 to move along the guide rail 201 .

[0110] Furthermore, if Figure 3 As shown, in order to realize the movable installation of the device carrier 101 on the guide rail 201, track grooves 25 are respectively provided at the lower parts of the two side surfaces of the guide rail 201.

[0111] As for the design of the carrier driving device 300 , it includes a carrier driver 31 , at least two rollers 32 and a carrier transmission assembly.

[0112] At least two rollers 32 are pivotally connected to the device carrier 101 and extend into the track grooves 25 respectively.

[0113] The carrier driver 31 is installed on the device carrier 101 and connected to at least one roller 32 via a transmission assembly, and is used to drive the connected roller 32 to rotate to drive the device carrier 101 to move.

[0114] Furthermore, if Figure 3 As shown, there are two rollers 32 , both of which are fixed with a wheel axle 34 ; taking the arrangement of two rollers 32 as an example, one roller 32 is arranged on one side to extend into the corresponding track groove 25 .

[0115] The axle 34 is pivotally connected to the device carrier 101 , and both ends of the axle 34 can be rotatably fixed by pulleys / bearings.

[0116] The carrier transmission assembly includes two transmission shafts 33. The carrier driver 31 is a double-headed rotary motor, and driving gears 35 are fixed on the output shafts at both ends, and driven gears 36 are fixed on the axle 34. The double-headed rotary motor setting can reduce the number of motors and make the overall structure more compact.

[0117] The two transmission shafts 33 are pivotally connected to the device carrier 101 and are arranged one-to-one with the wheel shafts 34. The two ends of the transmission shafts 33 are provided with transmission gears 331 respectively meshing with the driving gear 35 and the driven gear 36. When the two output shafts of the carrier driver 31 rotate, the two transmission shafts 33 are driven to rotate through the cooperation between the driving gear 35 and the transmission gear 331, and then the wheel shaft 34 is driven to rotate through the cooperation between the transmission gear 331 and the driven gear 36, and then the two rollers 32 are driven to rotate, so as to realize the movement of the device carrier 101.

[0118] The above design enables the carrier driver 31 to be disposed below or to the side of the roller 32 without the need for axial arrangement, thereby effectively reducing the overall structural size and making it more compact.

[0119] Furthermore, in order to prevent the roller 32 from slipping on the track groove 25 when rotating, thereby affecting the normal movement of the device carrier 101, as shown in FIG. Figure 5As shown, the present application lays a rack 37 in the track groove 25, and a tooth structure meshing with the rack 37 is provided on the outer circumference of the roller 32. The rack 37 can be replaced by a synchronous belt, and the corresponding roller 32 can be a synchronous pulley, without specific limitation.

[0120] Furthermore, if Figure 4 As shown, in order to better transmit power and avoid using too many cables, the present application provides a through cavity 27 in the guide rail 201, and conductive copper busbars 203 are fixed on both sides of the through cavity 27; the conductive copper busbars 203 are connected to the inner side of the guide rail 201 through an insulating support structure 26 such as an insulator. Figure 5 As shown, in order to further strengthen the overall structure, a corresponding metal reinforcement structure 29 is also provided in the through cavity 27 .

[0121] A power receiving device 400 is fixed on the device carrier 101 , and a avoidance groove 28 is provided at the bottom of the guide rail 201 to communicate with the middle through cavity 27 and avoid movement of the power receiving device 400 . One end of the power receiving device 400 extends into the middle through cavity 27 through the avoidance groove 28 and is located between two conductive copper busbars 203 .

[0122] Two movable contact members 401 are provided at one end of the power receiving device 400. A contact driving mechanism 402 connected to the two contact members 401 and used to drive the two contact members 401 to contact the conductive copper busbar 203 for electrical conduction is installed at one end of the power receiving device 400. The contact members 401 can slide in contact with the conductive copper busbar 203. When electrical conduction is required, the two contact members 401 are driven by the contact driving mechanism 402 to move to contact the conductive copper busbar 203, thereby achieving power reception. The slidable contact design between the contact members 401 and the conductive copper busbar 203 can achieve that the power reception is not affected during the sliding process.

[0123] Furthermore, if Figure 5 As shown, the contact members 401 are connected to the power receiving device 400 via the crank arm 45 .

[0124] One end of the crank arm 45 is hinged to the contact member 401 via a rotating shaft, and the other end is hinged to the power receiving device 400 via a rotating shaft, thereby realizing a flippable movable setting of the power receiving device 400. Moreover, under this design, it is also convenient for the contact member 401 to adaptively adjust the contact angle after sliding wear occurs, thereby ensuring stable contact with the conductive copper busbar 203.

[0125] The contact drive mechanism 402 can be an electromagnetic spring mechanism installed between the two contact members 401. After power is turned on, the spring is triggered to push the contact member 401 to contact the conductive copper busbar 203. In order to facilitate the installation and matching with the electromagnetic spring structure, a matching hole 44 is provided on the contact member 401 for one end of the electromagnetic spring mechanism to be inserted.

[0126] The main structure 41 of the power receiving device 400 is as follows Figure 5 As shown, the seat structure plays a bearing role. The specific structure can be designed according to actual needs without limitation.

[0128] The main structure 41 is rotatably connected to the power receiving device 400, and the carbon slide plate 43 is insulated and connected to the main structure 41 through the insulating layer 42, and can slide in contact with the conductive copper busbar 203. The carbon slide plate 43 is used to achieve contact and sliding with the conductive copper busbar 203, effectively reducing damage to the conductive copper busbar 203 due to sliding friction, and effectively ensuring the contact surface and conductive performance.

[0129] One end of the conductive wire of the power receiving device 400 passes through the main structure 41 and the insulating layer 42 and is electrically connected to the carbon slide plate 43 .

[0130] Further, taking the charging driving device 102 as an example to drive the charging pile gun 103 to move to the preset charging preparation position, as shown in FIG. Figure 3 As shown, the charging drive device 102 may specifically include a charging driver 11 and a cable ring 12. The cable ring 12 may be replaced by a reel without limitation.

[0131] The cable ring 12 is wound with a pile head cable 104 connected to the charging pile gun 103. One end of the pile head cable 104 extends out of the device carrier 101 and is connected to the charging pile gun 103. The charging driver 11 is connected to the cable ring 12 to drive the cable ring 12 to rotate, so as to drive the charging pile gun 103 to move up and down. Under this design, the charging driver 11 can be a servo motor that can rotate forward and reverse. When charging is required, the charging driver 11 drives the cable ring 12 to rotate, thereby releasing the pile head cable 104. After the charging pile gun 103 is lowered to a certain height, the user can insert the charging pile gun 103 into the car charging port for charging.

[0132] Further, taking the charging drive device 102 as an example of driving the charging pile gun 103 to move to a position docking with the charging port of the object to be charged, the charging drive device 102 includes a robotic arm 13 , a radar 15 and a camera 14 .

[0133] The radar 15 is installed at the bottom of the device carrier 101, and the camera 14 is installed at the end of the mechanical arm 13; the radar 15 and the camera 14 are used to collect information to facilitate the control of the mechanical arm 13. In the embodiment of the above-mentioned cable ring 12 design, the camera 14 can also be added to accurately control the moving position of the charging pile gun 103.

[0134] The end of the mechanical arm 13 is connected to the charging pile gun 103, and is used to drive the charging pile gun 103 to move. The mechanical arm 13 can be a multi-axis manipulator mechanism, such as a five-axis manipulator, etc., without limitation.

[0135] Furthermore, a drawer module 500 that can be pulled out is installed in the device carrier 101 , and the drawer module 500 is provided with an installation cavity.

[0136] The drawer module 500 is provided with a power receiving point 501. When the drawer module 500 is pushed into place, the power receiving point 501 is in conductive contact with the other end of the power receiving device 400. The drawer module 500 can be two, and they are distributed up and down. The drawer module 500 located on the upper side can be used to install the corresponding main control module, wherein the main control module is as follows. Figure 2 As shown, it may include a central processor 51 with a communication module, a contactor and fuse current limiter integration 52 , a main circuit breaker and surge protector integration 53 , a charging system controller 54 with a meter, and a first motor control module 38 for controlling the carrier drive 31 .

[0137] The lower drawer module 500 may be used to install the charging driver 11 and the cable ring 12 , and the second motor control module 16 for controlling the charging driver 11 , or to install the manipulator control module 17 for controlling the manipulator 13 .

[0138] In order to better achieve the pull-out cooperation, the side of the drawer module 500 is provided with a pull-out track 502, and the power receiving point 501 of the upper drawer module 500 can be a groove structure, which is arranged above the drawer module 500, and the other end of the conductive wire of the power receiving device 400 extends into the power receiving point 501 and can slide in contact with the power receiving point 501. It is convenient to achieve electrical contact during the sliding process. The power receiving point 501 on the drawer module 500 located below can be set on the back of the drawer module 500 without restriction.

[0139] In addition, the portion of the device carrier 101 that slides with the guide rail 201 can also adopt a modular design, that is, the carrier driving device 300 can achieve a modular design. Under this design, the carrier driving device 300 has a corresponding main structure 41, and the main structure 41 is configured with a carrier driver 31, a roller 32 and a transmission assembly. The main structure 41 is modularly connected to the device carrier 101.

[0140] The modular design allows for different modes to be composed according to needs and the use of different functional modules, which can greatly reduce the cost of subsequent upgrades and modifications.

[0141] Furthermore, a lock 503 corresponding to the drawer module 500 is provided on the side of the device carrier 101. When the drawer module 500 is pushed into place, the lock 503 can be connected with the drawer module 500 to lock the drawer module 500. The lock 503 can be a quick release pin or other locking mechanism, without limitation. Taking the quick release pin as an example, the drawer module 500 is provided with a pin hole for inserting the quick release pin.
