[0050] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 9 and Figure 13 As shown, the automatic function panel 9 is secured to a fixed block 42 on the side facing the shift lever 7. A third proximity switch 43 is disposed on the fixed block 42, and a third magnet 51 is disposed on the sleeve block 12. When the shift lever 7 is pushed into the parking slot 6 and the sleeve block 12 approaches the fixed block 42, the third proximity switch 43 senses the proximity of the third magnet 51 and outputs a signal. When the shift lever 7 is pushed into the parking slot 6 and locked within the parking slot 6, the third magnet 51 on the sleeve block 12 approaches the third proximity switch 43, outputting a parking signal and executing the parking operation.

A main oil suction cotton swab 28 is inserted into the bottom end of the shift grip 19. The top of the main oil suction cotton swab 28 is connected to the branch oil suction cotton swab 29, and the bottom end of the main oil suction cotton swab 28 extends into the functional chamber 25. Both ends of the branch oil suction cotton swab 29 are provided with a first magnet 20. A pair of first magnets 20 respectively penetrate and protrude from the upper surface of the block 21 and the hook block 24. Lubricating oil is injected into the oil pan 11. When the shift grip 19 is pushed down and rebounded to reset for shifting, the piston 27 at the bottom end of the shift grip 19 is in the functional chamber. Air is compressed in the cavity 25, and the suction force generated can suck the lubricating oil in the oil pan 11 into the functional cavity 25 through the oil suction hose 23, and in the process of pressing the shift lever 19 downward, the lubricating oil penetrates the main oil suction cotton swab 28, and then the lubricating oil penetrates the branch oil suction cotton swab 29 and the oil suction cotton block 30. When the block 21 is inserted into the card slot 18 or the hook block 24 is hooked into the connecting hole 44, pressure will be exerted on the oil suction cotton block 30, forcing the lubricating oil in the oil suction cotton block 30 to be squeezed out. The squeezed lubricating oil can flow to the surface of the block 21, the surface of the hook block 24, the limit groove 13 and the card slot 18, the surface of the shift plate 31, and the hinge of the sleeve arm 16 and the hinge seat 17, to lubricate and protect the swinging gear shifting contact surface and the hinge of the gear lever 7, reduce wear, and improve the smoothness of gear shifting. Excess lubricating oil can drip into the oil pan 11 for recovery.

[0053] When in use, the shifter is divided into two areas, the left side is the manual shift area, and the right side is the automatic shift area;

[0054] Push the shift lever 7 into the shift panel 3 to enter the manual shift mode. The first return torsion spring assembled in the hinge seat 17 forces the sleeve arm 16 to drive the shift lever 7 to swing toward the manual function panel 8, so that the shift lever 7 maintains the manual shift state, and pushes the shift grip 19 downward. The shift grip 19 pushes the block 21 downward, and the block 21 disengages from the slot 18 in the limit slot 13. At this time, push the shift lever 7 back and forth to perform the shift operation. The first magnet 20 on the sleeve block 12 passes through the first proximity switch 10 corresponding to different gear positions. Therefore, when the shift lever 7 is in different gear positions, the first magnet 20 corresponds to different first proximity switches 10 to output signals, perform gear position judgment and execute corresponding actions.

[0055] Push the shift handle 19 downward to disengage the card block 21 from the card slot 18, and at the same time push the gear lever 7 into the automatic gear slot 5 to enter the automatic gear shift mode. At this time, the hook block 24 is inserted into the connecting hole 44. After releasing the shift handle 19, the elastic force of the return spring 26 pushes the shift handle 19 to move up and reset. The hook block 24 is hooked in the connecting hole 44. At this time, the gear lever 7 is pushed back and forth to shift. The shift plate 31 swings synchronously with the gear lever 7 driven by the hook block 24. At this time, the second magnet 38 on the support rod 37 Approaching a pair of second proximity switches 33, the second magnet 38 approaches different second proximity switches 33 to output the upshift and downshift signals, thereby realizing the automatic shifting function; while automatically shifting, the driven swing arm 35 swings along with the shift plate 31, and the elastic force of the limit spring 49 is used to push the top column 47 to engage with the tooth groove 46 on the feedback rail 34. The swinging of the driven swing arm 35 can make the end of the top column 47 bounce on multiple tooth grooves 46, generating mechanical bounce feedback, so that the driver can intuitively feel the automatic shifting process.

[0056] The lever 7 is pushed to be embedded in the parking slot 6 and locked in the parking slot 6. At this time, the third magnet 51 on the sleeve 12 is close to the third proximity switch 43, and a parking signal is output to execute the parking operation.

[0057] In a further embodiment, lubricating oil is injected into the oil pan 11. When the shift lever 19 is pushed down and rebounded to perform the shift operation, the piston 27 at the bottom end of the shift lever 19 compresses the air in the functional chamber 25. The suction force generated can suck the lubricating oil in the oil pan 11 into the functional chamber 25 through the oil suction hose 23. In the process of pressing the shift lever 19 down, the lubricating oil soaks through the main oil suction cotton swab 28, and then the lubricating oil soaks through the branch oil suction cotton swab 29 and the oil suction cotton block 30, and the gear lever block 21 is locked. When the slot 18 or the hook block 24 is hooked into the connecting hole 44, pressure will be exerted on the oil-absorbing cotton block 30, forcing the lubricating oil in the oil-absorbing cotton block 30 to be squeezed out. The squeezed lubricating oil can flow to the surface of the block 21, the surface of the hook block 24, the limit groove 13 and the slot 18, the surface of the shift plate 31, and the hinge of the sleeve arm 16 and the hinge seat 17, to lubricate and protect the swinging gear shifting contact surface and the hinge of the gear lever 7, reduce wear, and improve the smoothness of gear shifting. Excess lubricating oil can drip into the oil pan 11 for recovery.
