As shown in fig. 1, an embodiment of the present invention provides a transfer case shift mechanism, including: the high-low gear cylinder 2 is positioned in the transfer case shell 1 and is detachably connected with the transfer case shell 1; the neutral position cylinder 3 is detachably connected with the high-low gear cylinder 2; the high-low gear cylinder 2 and the neutral gear cylinder 3 are respectively connected with at least one electromagnetic valve.
Specifically, the electromagnetic valve includes: a first solenoid valve 7, a second solenoid valve 8 and a third solenoid valve 9.
More specifically, the first electromagnetic valve 7 is positioned on the transfer case shell 1 and is detachably connected with the high-low gear cylinder 2; the second electromagnetic valve 8 and the third electromagnetic valve 9 are respectively positioned on the neutral cylinder 3 and are detachably connected with the neutral cylinder 3.
Preferably, the solenoid valve is a pneumatic solenoid valve. The electromagnetic valve is provided with an electromagnetic valve sealing ring 10, and the electromagnetic valve sealing ring 10 is used for preventing gas passing through the electromagnetic valve from leaking outwards, so that the sealing effect of the electromagnetic valve is improved.
Here, a sealing ring 15 is provided at a junction of the high-low range cylinder 2 and the neutral cylinder 3, and the sealing ring 15 is used for preventing gas leakage at the junction of the high-low range cylinder 2 and the neutral cylinder 3, thereby improving sealing effect.
As shown in fig. 1, a high-low gear piston 5 detachably connected to one end of a transfer gear shift lever 4 is provided in the high-low gear cylinder 2, and the high-low gear piston 5 is slidable along an inner wall of the high-low gear cylinder 2.
The other end of the transfer case shift lever 4 is connected to the transfer case body.
Specifically, the high-low gear piston 5 is a cylindrical piston, and a through hole is formed in the piston for the transfer gear shift lever 4 to pass through, that is, one end of the transfer gear shift lever 4 passes through the through hole in the high-low gear piston 5, and the high-low gear piston 5 and the transfer gear shift lever 4 are fixedly connected through a bolt.
Specifically, a high-low range piston ring 11 is provided on the peripheral side surface of the high-low range piston 5, and the high-low range piston ring 11 is used for sealing the gas in the high-low range cylinder 2 and preventing gas leakage.
As shown in fig. 1, the transfer gear shift lever 4 is partially located in the high-low range cylinder 2. That is, the high-low gear cylinder 2 is provided with a channel for the transfer gear shift lever 4 to penetrate through and match with the transfer gear shift lever 4 in structure.
Specifically, the transfer case shift lever 4 is provided with a seal ring 16 on the peripheral side surface thereof, and the seal ring 16 is used to prevent gas in the high-low stage cylinder 2 from leaking into the transfer case 1.

The piston base 12 is a cylindrical base, and a neutral piston ring 14 is disposed on a peripheral side surface of the piston base 12, and the neutral piston ring 14 is used for sealing gas in the neutral cylinder 3 and preventing gas leakage.
Here, the diameter of the piston base 12 is larger than the diameter of the high-low stage piston 5. That is, when the piston base 12 of the neutral piston 6 slides along the inner wall of the neutral cylinder 3 to the opening end of the neutral cylinder 3, that is, the leftmost end of the neutral cylinder 3 as shown in fig. 1, since the diameter of the piston base 12 is larger than that of the high-low gear piston 5, the piston base 12 is limited at the leftmost end of the neutral cylinder 3 and cannot enter the high-low gear cylinder 2, and it is ensured that the transfer gear is put into neutral.

The transfer case gearshift gives an electric signal through the gearshift switch, and controls the electromagnetic valve to carry out on-off of an air passage of the air cylinder, so that the change of the transfer case gears is realized. The method comprises the following specific steps:
as shown in fig. 2, when the first solenoid valve 7 is operated, the first compressed gas enters the high-low range cylinder 2 through the first solenoid valve 7, the transfer case 1 and the first gas passage of the high-low range cylinder 2, i.e. the left cylinder of the high-low range piston 5, pushes the high-low range piston 5, and here, pushes the high-low range piston 5 to the rightmost end of the high-low range cylinder 2 (as shown in fig. 2), and simultaneously the high-low range piston 5 drives the neutral piston 6, i.e. the transfer gear shift lever 4 on the high-low range piston 5 pushes the neutral piston 6 to the rightmost end of the neutral cylinder 3 (as shown in fig. 2), so that the transfer is shifted into the low range.
As shown in fig. 3, when the first electromagnetic valve 7 and the third electromagnetic valve 9 are operated, a first compressed gas enters the high-low gear cylinder 2 through the first electromagnetic valve 7, the transfer case 1 and the first gas path of the high-low gear cylinder 2, and a third compressed gas enters the neutral cylinder 3 through the third electromagnetic valve 9 and the third gas path of the neutral cylinder 3, the first compressed gas pushes the high-low gear piston 5, and the third compressed gas pushes the neutral piston 6, where it should be noted that the first compressed gas pushes the high-low gear piston 5 to the middle position of the high-low gear cylinder 2, and the third compressed gas pushes the neutral piston 6 to the leftmost end of the neutral cylinder 3 (as shown in fig. 3), so that the transfer is put into neutral.
Here, the thrust of the third compressed gas in the neutral cylinder 3 is greater than the thrust of the first compressed gas in the high-low range cylinder 2, and the transfer can be put into the neutral position and kept stable due to the limit action of the right-side end face of the high-low range cylinder 2 against the piston base 12 of the neutral piston 6.
