[0011] Figure 5 , 6 This is a structural diagram of the present invention in operation. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0013] like Figure 1 , 2 A multi-link drive structure for a gear shifter, as shown in figures 3, 4, and 5, includes a base 1, a right shift bracket 2, and a left shift bracket 3. The right shift bracket 2 and the left shift bracket 3 are connected together and mounted on the base 1. The upper inner wall of the left shift bracket 3 is provided with a bushing seat a21 and a bushing seat b24. An operating lever assembly 4 has cylinders a at both ends, which are inserted into the bushing seat a21 through bushings a6. The main body of the operating lever assembly 4 is fan-shaped, and a bushing groove 22 is provided at the front of the fan-shaped body. A shaft is provided in the bushing groove 22. The sleeve a7 has a spherical groove in the middle, and a spherical shaft is provided in the spherical groove. The spherical shaft is located on the upper right shaft hole of the cable-driven rocker arm assembly 5. The cable-driven rocker arm assembly 5 has cylinders b on both sides of the rear part. The cylinders b are inserted into the bushing seat b24 through the bushing b. The lower left side of the cable-driven rocker arm assembly 5 has a limiting shaft 25. The limiting shaft 25 is locked on the lower limiting groove 26 of the left shift bracket 3. The upper inner wall of the right shift bracket 2 has bushing seat c and bushing seat d. The cylinder a is inserted into the bushing seat c through the bushing c, and the cylinder b is inserted into the bushing seat d through the bushing d.

[0014] The base 1 has a mounting groove in the middle and a snap-fit ​​on the front side of the mounting groove. The lower front part of the right shift bracket 2 and the left shift bracket 3 has a protrusion that snaps into the snap-fit. The front part of the left shift bracket 3 has a pin a31, a pin b and a pin c. The front part of the right shift bracket 2 has a pin seat a32, a pin seat b and a pin seat c. Pin a31 is inserted into pin seat a32, pin b is inserted into pin seat b and pin c is inserted into pin seat c.

[0015] The bushing seat a21 is provided with a retaining ring. The cable-driven rocker arm assembly 5 is inverted L-shaped. The upper middle part of the cable-driven rocker arm assembly 5 is provided with a socket. The positioning pin 13 is inserted into the socket. The positioning pin 13 is inserted into the socket from the left shift bracket 3.

[0016] In use, the joystick assembly 4 is a combination of a metal joystick and a plastic component. Its purpose is to drive the human-machine interface point to rotate around a rotation axis, and to drive the cable-driven rocker arm assembly to rotate around the rotation axis. Bushing a7 is made of plastic and receives the driving force from the joystick assembly, converting linear motion into rotational force. The cable-driven rocker arm assembly 5 is a combination of a metal component and a plastic component. It receives the rotational force from the joystick and rotates around the central axis of its body, pulling the flexible shaft to drive gear shifting. Bushings a, b, c, and d are made of plastic and are elastic components, positioning the joystick assembly and the cable-driven rocker arm assembly. The arm assembly is positioned in the outer housing to compensate for the matching gap and to provide lubrication during movement. The force application point of the shifter is the human-machine interface point. When the drive lever assembly rotates, lever arm a27 and lever arm c29 are the same component and rotate synchronously, converting into a pull-lock drive rocker arm assembly to rotate synchronously around the rotation axis. After the angle conversion of lever arm b28 and lever arm d30, a four-bar linkage mechanism is formed. The characteristic is that the force application point and the drive point move in the same direction. The purpose is to achieve small-angle shifting of the lever assembly without adjusting the shifting direction of the gearbox.
