[0036] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0037] Embodiment 1

[0038] like Figure 1 As shown, this embodiment proposes a rail-mounted mobile charging robot, the upper part of the robot body 1 is connected to the hanging wheel system 5, the lower part of the robot body 1 is connected to the charging system 2, the hanging wheel system 5 is mounted under the robot track 3, the track power supply system 6 is fixed inside the robot track 3, and the track positioning system 4 is fixed outside the robot track 3. The hanging wheel system 5 is responsible for carrying the robot body 1 and the charging system 2 while meeting the needs of the robot moving along the robot track 3, the track positioning system 4 is used to meet the positioning needs of the robot, and the power supply system 6 provides the power needs of the robot movement and the charging system 2 for external charging.

[0039] The robot body 1 includes: a housing module 12 , a robot frame 11 , a communication and electrical module 13 , a positioning module 14 , a collector module 15 and a driving module 7 . Figure 2 and Figure 3The structure diagrams after the front and rear shells of the shell module 12 are removed are shown respectively. The robot is built on the robot frame 11, on which the shell module 12, the communication and electrical module 13, the second positioning module 14, the collector module 15, the drive module 7, and the charging system 2 are respectively installed and fixed to form the overall structure of the robot. The track power supply system 6 includes a power supply and a conductor laid on the robot track. The collector module 15 is provided with multiple collectors for conveniently taking power from the track power supply system 6. It has strong expandability and can be adapted to a variety of busbar structures. Multiple sets of collector structures can be installed to ensure that the robot obtains stable and reliable power supply.

[0040] Specifically, the track positioning system 4 includes a second positioning module 14 and a first positioning module. The first positioning module can be a bracket set on the robot track 3 and an electronic tag set on the bracket. The second positioning module 14 includes a positioning baffle extending from the top of the robot body, and a tag reader is provided on the top of the positioning baffle.

[0041] The shell module 12 makes the robot look more beautiful and has a certain ability to protect the internal components. The utility model adopts a double shell for protection, so as to achieve excellent dustproof and waterproof performance and effectively extend the life of internal components. The communication and electrical module 13 is the core of controlling the movement and action of the robot, and at the same time completes tasks such as sending and receiving data and interacting with the outside world. The second positioning module 14 cooperates with the track positioning system 4 to realize the positioning function of the robot, and the collector module 15 cooperates to realize the transmission of electrical energy from the external power supply to the robot. The drive module 7 provides power for the robot to move on the robot track system 3.

[0042] like Figure 4 and Figure 5 The figure shows the structure diagram of the charging system 2. In this structure, the slip ring fixing plate 23 and the motor fixing plate 29 constitute the structural frame of the charging system 2, which is fixed on the robot frame 11. The two are connected through the guide groove 22 and the guide roller 24. The slip ring 26 is fixed on the slip ring fixing plate 23. The reduction motor 25 is fixed on the motor fixing plate 29. The output shaft end of the reduction motor 25 is fixed with a spiral winding drum 27. The bearing 28 is used to support the spiral winding drum 27. The cable of the charging gun belt line 21 is coiled in the spiral winding drum 27.

[0043] This structure can realize the retracting and extending action of the gun head of the charging gun cable 21. The reduction motor 25 provides the power for the action, the spiral winding drum 27 provides the retracting and extending space of the cable of the charging gun cable 21, the guide groove 22 and the guide roller 24 constrain the freedom of the cable of the charging gun cable 21, and the bearing 28 ensures the stable support of the system.

[0044] like Figure 6 and Figure 7The figure shows the structure of the driving module 7. In this structure, the spring bracket 77 and the swing shaft 72 are fixed on the robot frame 11. The swing bracket 74 is movably connected with the swing shaft 72 through the swing bearing 73. The driving motor bracket 78 is fixed on the swing bracket 74. The driving motor 71 is connected to the driving wheel 75 through the connecting piece 710. The driving motor 71 is fixed on the motor bracket 78. The compression spring 76 is between the spring bracket 74 and the swing bracket 74 to apply upward pressure to the swing bracket 74.

[0045] This structure can realize the rotation of the driving wheel 75. Since the spring bracket 77 and the swing shaft 72 are fixed, the driving wheel 75 is tightly pressed on the robot track 3 under the action of the compression spring 76, thereby achieving the purpose of driving the entire robot to run on the track. The hanging wheel system adopts a specific angle hanging wheel group, which can simultaneously meet the needs of robot mounting, left and right direction positioning, etc.

[0046] like Figure 8 and Fig. 9 As shown, in this structure, two wheel bearings 54 are installed inside the wheel 51, and a wheel shaft 52 passes through the center. The wheel shaft 52 is fixed on the wheel bracket 53, and the wheel bracket 53 is fixed on the robot frame 11. There are four groups of this structure evenly distributed on both sides to provide reliable support for the entire robot. The hanging rail structure of the utility model can reduce the demand for space above the robot track when deploying, especially in indoor parking lots with limited height. Compared with the structure where the robot body walks above the track, the height required for the hanging wheel assembly is small, which avoids the robot track being set too low to affect the entry and exit of the car.

[0047] The rail-mounted mobile charging robot hanging wheel system 5 of the utility model carries a robot body 1 and a charging system 2. Under the power provided by the driving module 7, the robot moves along the robot track 3. Whenever the positioning module 14 on the robot body 1 detects that the track positioning system 4 on the robot track 3 has a signal output, under the processing of the communication electrical module 13, the robot stops moving at the desired position. At this time, the charging system 2 can retract and extend the charging gun with wire 21. The charging gun can be put down to charge the external device, and the charging gun can be retracted after charging is completed.

[0048] The rail-mounted mobile charging robot of the utility model can work according to the following process:

[0049] (1) A person manually issues a command to charge at the charging location / parking space;

[0050] (2) The robot moves to the parking space that needs to be charged according to the received instructions;

[0051] (3) The robot automatically puts down the charging gun;

[0052] (4) Manually insert the gun into the charging port on the vehicle;

[0053] (5) Charging;

[0054] (6) When charging is finished, manually remove the charging gun from the vehicle and issue a command to complete charging;

[0055] (7) The robot automatically retracts the charging gun and waits for the next charging instruction.

[0056] The rail-mounted mobile charging robot designed by the utility model can alleviate the problem of insufficient charging infrastructure in existing parking lots. For vehicles that need to park temporarily or are in urgent need of charging, the robot can respond quickly and provide fast charging services. In the scenario where fuel vehicles and new energy vehicles share parking spaces, the mobile charging robot can effectively alleviate the competition between the two, and new energy vehicle owners do not have to worry about wasting time looking for parking spaces with charging piles. It also helps to promote the unmanned and intelligent process of the automotive industry.

[0057] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
