At this time, the T-thread sleeve 8 on the screw rod 7 is raised and lowered, thereby driving the shift fork 2 to move, and then the shift adjustment of the automobile transmission is realized during the displacement of the shift fork 2. This electronic control method replaces the traditional manual shifting method, so that the shift adjustment of the automobile transmission can be conveniently realized.

[0023] Specifically, the transmission structure 5 includes a gear 501 and a tooth groove 502. The gear 501 is arranged on the rotating shaft at the output end of the motor 4. The tooth groove 502 is opened around the top of the base 6. The tooth groove 502 is engaged with the gear 501. The motor 4 drives the gear 501 to rotate, and then the gear 501 cooperates with the tooth groove 502 to drive the base 6 to rotate.

[0024] Furthermore, the docking seat 9 is U-shaped, and clamping grooves 901 are opened at both ends of the rear side of the docking seat 9. The U-shaped docking seat 9 is inserted into the two sides of the top of the T-shaped threaded sleeve 8 through the clamping grooves 901.

[0025] Furthermore, the two ends of the rear side of the docking seat 9 are formed into arc-shaped grooves 902, and two sets of symmetrical limiting rods 303 are arranged inside the front cavity 302 on the rear side of the T-type threaded sleeve 8.

[0026] In the embodiment of the present invention, rectangular through holes 903 are provided on the top and bottom rear sides of the docking seat 9, an L-shaped reinforcement frame 11 is movably arranged in the rectangular through hole 903, and an L-shaped buckle groove 801 symmetrical to the rectangular through hole 903 is provided on the top rear side of the T-shaped threaded sleeve 8; a locking end 1101 is provided on one end of the L-shaped reinforcement frame 11 facing the rectangular through hole 903, and a mounting screw hole 1102 is provided on the end of the L-shaped reinforcement frame 11 facing the fixing bolt 10; the length of the rectangular through hole 903 is the same as the length of the locking end 1101, and the opening length of the L-shaped buckle groove 801 is the same as the length of the locking end 1101; when the docking seat 9 is inserted into the T-shaped threaded sleeve 8 for fixed installation, the L-shaped reinforcement frame 11 can be inserted into the rectangular through hole 903 first, and at this time the locking end of the L-shaped reinforcement frame 11 is locked. The end 1101 is located in the L-shaped buckle groove 801 at the rear of the top of the T-shaped threaded sleeve 8, and then the L-shaped reinforcement frame 11 is pushed forward. At this time, the engaging end 1101 of the L-shaped reinforcement frame 11 is buckled in the L-shaped buckle groove 801, and then the fixing bolt 10 is screwed into the front end of the docking seat 9. At this time, the fixing bolt 10 passes through the docking seat 9, the T-shaped threaded sleeve 8 and the mounting screw hole 1102 of the L-shaped reinforcement frame 11. At this time, the L-shaped reinforcement frame 11 is limited by the fixing bolt 10 and cannot move. Therefore, the L-shaped reinforcement frame 11 is buckled with the L-shaped buckle groove 801, which can fix the rear end of the docking seat 9 and the T-shaped threaded sleeve 8 after being inserted, further improving the stability of the connection and installation between the docking seat 9 and the T-shaped threaded sleeve 8, so that the electronic drive structure 1 can more stably drive the shift fork 2 to move and shift.

[0027] Working principle: This embodiment provides a shift mechanism. First, the shift fork 2 is inserted into the T-shaped threaded sleeve 8 through the docking seat 9. Then, the fixing bolt 10 is screwed on the front end of the top of the docking seat 9 to fix it, thereby fixing the shift fork 2 to the T-shaped threaded sleeve 8. Then, the personnel can directly control the motor 4 to work. Then, the motor 4 drives the base 6 and the screw rod 7 to rotate through the transmission structure 5. At this time, the T-shaped threaded sleeve 8 on the screw rod 7 is raised and lowered, thereby driving the shift fork 2 to move. Then, during the displacement of the shift fork 2, the shift adjustment of the automobile transmission is realized. This electronic control method replaces the traditional manual shifting method, thereby conveniently realizing the shift adjustment of the automobile transmission.

[0028] Secondly, when the docking seat 9 is inserted into the T-thread sleeve 8 for fixed installation, the L-shaped reinforcement frame 11 can be inserted into the rectangular through hole 903 first. At this time, the engaging end 1101 of the L-shaped reinforcement frame 11 is located in the L-shaped buckle groove 801 at the back of the top of the T-thread sleeve 8. Then, the L-shaped reinforcement frame 11 is pushed forward. At this time, the engaging end 1101 of the L-shaped reinforcement frame 11 is buckled in the L-shaped buckle groove 801. Then, the fixing bolt 10 is screwed into the front end of the docking seat 9. At this time, the fixing bolt 10 is inserted through the front end of the docking seat 9. Through the mounting screw holes 1102 of the docking seat 9, T-shaped threaded sleeve 8 and L-shaped reinforcement frame 11, the L-shaped reinforcement frame 11 is limited by the fixing bolts 10 and cannot move. Therefore, the L-shaped reinforcement frame 11 is engaged with the L-shaped buckle groove 801, which can fix the rear end of the docking seat 9 and the T-shaped threaded sleeve 8 after they are inserted, further improving the stability of the connection and installation between the docking seat 9 and the T-shaped threaded sleeve 8, so that the electronic drive structure 1 can more stably drive the shift fork 2 to move and shift gears.
