[0026] Reference Figure 1 As shown, a device for replacing gear oil of an automobile automatic transmission shown in the figure of the embodiment of the present invention includes an oil barrel box 1 and an equipment box 2. The oil barrel box 1 contains an oil barrel, and the equipment box 2 is provided with a pump 3 and a three-way valve 4. One port of the pump 3 is connected to an oil extraction pipe 7, and the other port is connected to the three-way valve 4. The other two ports of the three-way valve 4 are connected to an oil guide pipe 8. The other end of the oil extraction pipe 7 is movably connected to a quick connector 11. The two oil guide pipes 8 both penetrate into the interior of the oil barrel box 1 and are connected to the oil barrel. The quick connector 11 is movably connected to the automobile gearbox. A remote communicator 5 is fixedly installed on one side of the equipment box 2. The pump 3 is electrically connected to the remote communicator 5. The remote communicator 5 is remotely connected to a user terminal. The end of the oil guide pipe 8 that penetrates into the interior of the oil barrel box 1 is fixedly connected to a magnetic head 13. A power supply 6 is fixedly installed inside the equipment box 2. The pump 3 is electrically connected to the power supply 6.

[0027] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , by connecting the two sets of oil guide pipes 8 to a 4L oil barrel, one of which is used to hold new oil and the other is used to hold old oil, and connecting the oil extraction pipe 7 to the gearbox and using the oil extraction pipe 7 to drain the old oil in the gearbox, and then connecting the quick connector 11 - the transmission oil pan screw connector that can be connected to the gearbox - to the gearbox.

[0028] Then, a terminal (e.g., a mobile phone or remote control) or other device / program capable of remotely controlling the remote communication device 5 is used to control the three-way valve 4 and the pump 3, causing the three-way valve 4 and the pump 3 to pump 4L of new oil into the transmission. The quick connector 11 is then closed through the remote communication device 5, the vehicle is started, and gears are switched sequentially so that the new oil can penetrate various drive components in the transmission.

[0029] Then, the remote communication device 5 is driven to open the switch of the quick connector 11. On the other hand, the pump 3 is controlled to reverse, and the new oil that has soaked the various driving components in the gearbox is pumped out from the gearbox and discharged into the old oil barrel through the oil guide pipe 8. This step is to use the gearbox oil as cleaning oil and clean the gearbox.

[0030] Then, the remote communication device 5 controls another oil pipe 8 to pump new oil from another oil barrel into the gearbox, completing the gearbox oil replacement operation;

[0039] Then, the pump 3 is controlled by the terminal, i.e. a mobile phone or a remote controller, etc. which can remotely control the remote contactor 5, so that the pump 3 draws 4L new oil into the gearbox, and then the switch of the quick connector 11 is manually closed, the vehicle is started and the gears are switched in sequence, so that the new oil can soak into each driving part in the gearbox;

[0040] Then, the switch of the quick connector 11 is opened and the pump 3 is controlled to reverse, so that the new oil soaked into each driving part in the gearbox is drawn out from the gearbox and discharged into the old oil tank through the oil guide pipe 8, and the gearbox oil is used as cleaning oil to clean the gearbox;

[0041] Then, another oil guide pipe 8 is controlled to work by the remote contactor 5, and the new oil in another oil tank is drawn into the gearbox, and the replacement of the gearbox oil is completed;

[0042] Finally, the quick connector 11 is separated from the gearbox, and the complete replacement of the gearbox oil is completed.

[0043] It should be noted that in the technical solution, the existing technology is used to control the pump by the terminal, i.e. a mobile phone or a remote controller, etc. which can remotely control the remote contactor 5, and the current program technology is mature, and the existing remote control can also realize the forward and reverse rotation of the pump 3, and the implementation process is not described here, and of course, the remote control is not used, and the switch of the pump 3 can be manually controlled by a person, and the switch is set to be mechanical and then extended to a convenient position for control, and the purpose of oil replacement can also be achieved.
