Technical Field

[0001] The invention relates to the technical field of refueling robots, in particular to a portable refueling robot. Background Art

[0002] The car refueling robot is a robot that can work continuously for 24 hours. The refueling robot can save manpower because it can work continuously for 24 hours and there will be no overfilling or overflowing when refueling; it can reduce air pollution and protect the environment.

[0003] When refueling, the driver drives into the gas station just like entering a wash room. There is no need to get out of the car. Just open the car window, insert the electronic credit card into the electronic cash register, and select the oil number and amount you need.

[0004] Although some of the current car refueling robots are very convenient and labor-saving, due to their size, they can only be installed in fixed locations for refueling. When they need to go out for refueling, they cannot be moved at will, and their portability is poor, which leads to certain limitations.

[0005] To this end, the present invention provides a portable refueling robot to solve the above problems. Summary of the Invention

[0028] Beneficial effects

[0029] The present invention provides a portable refueling robot, which has the following beneficial effects compared with the prior art.

[0030] 1. This portable refueling robot is placed on a pallet and wheels are installed under the pallet, so that the pallet can be transported as a whole by a trailer, thereby achieving portability of the device. When refueling, the servo motor can be started to drive the screw to rotate. When the screw rotates, it can drive the slider to slide on the outside of the guide rail, thereby changing the horizontal position of the refueling assembly above the slider, so that it can be better aligned with the car's refueling port.

[0031] 2. This portable refueling robot can change the horizontal angle of the refueling gun by rotating the base. The direction and position of the refueling gun can be freely changed within a certain range through the main arm, telescopic arm and forearm. The telescopic arm can also extend the movable distance of the refueling gun, thereby realizing the free movement of the refueling gun, so that it can be better aligned with the car's refueling port when refueling.

[0032] 3. The portable refueling robot transmits the rotation of the screw to the rotary wheel through the transmission of the transmission assembly. Through the rotation of the rotary wheel, under the action of the two connecting rods, no matter what the rotation direction of the screw is, the pressurizing piston can be driven to reciprocate. When reciprocating, the pressurizing piston inhales air from the outside through the first one-way valve and discharges it through the second one-way valve, thereby achieving the effect of pressurizing the other side of the second one-way valve when the refueling assembly moves.

[0033] 4. The portable refueling robot is pressurized through the second one-way valve. Air will enter the fixed box through the second one-way valve. The pressure inside the fixed box will increase, thereby pushing the movable piston to move. The fixed ring can be moved to the fixed groove through the movable rod. The teeth on the inner side of the fixed ring can be stuck in the fixed groove to fix the wheel axle. This realizes that the equipment is automatically braked and fixed when the refueling assembly moves.

[0034] The pressure can be balanced through the balancing valve to prevent equipment failure due to excessive pressure inside the fixed box. After refueling is completed, the gas inside the fixed box is discharged through the pressure relief valve, and then the fixing ring is reset by moving the spring on the piston, thereby releasing the restriction on the wheel.

[0051] In this embodiment, when the translation assembly 2 starts to adjust the refueling position, the rotation of the screw rod 23 can drive the large pulley 41 to rotate through the extension shaft 46, and then drive the transmission shaft 44 to rotate through the belt 42 and the small pulley 43, thereby realizing the transmission of the power of the translation assembly 2 to the inside of the pressurizing assembly 5 through the transmission assembly 4.

[0052] The pressurizing assembly 5 includes a pressurizing box 51, a runner 52, a second connecting rod 53, a pressurizing piston 54, a first one-way valve 55 and a second one-way valve 56.
