To control the turbine 21 to switch between three states: synchronous rotation with the first drive gear 22, staggered with the first drive gear 22 and the second drive gear 23, and synchronous rotation with the second drive gear 23, that is, when the clutch 24 is paired with the first drive gear 22 and staggered with the second drive gear 23, the turbine 21 rotates synchronously with the first drive gear 22, when the clutch 24 is not paired with the first drive gear 22 and the second drive gear 23, the rotation of the turbine 21 does not affect the first drive gear 22 and the second drive gear 23, and when the clutch 24 is paired with the second drive gear 23 and staggered with the first drive gear, the turbine 21 rotates synchronously with the second drive gear 23.

In this way, when the turbine 21 is synchronized with the first driving gear 22, the fifth gear ring and the sixth gear ring are staggered, and the seventh gear ring and the eighth gear ring are meshed at the same time, so as to prevent the second driving gear 23 from sliding, that is, the vehicle lateral moving device is controlled not to fall when it moves horizontally; when the turbine 21 is synchronized with the second driving gear 23, the seventh gear ring and the eighth gear ring are staggered, that is, the fifth gear ring and the sixth gear ring are meshed at the same time, so as to prevent the first driving gear 22 from rotating, that is, the vehicle lateral moving device is controlled not to move horizontally when it moves up and down, thereby ensuring the stability and safety of the mechanism.

[0055] See also Figure 4 The joystick includes a sleeve 31, a mounting seat 33 and a mounting shaft 37; two mounting seats 33 are installed at the lower end of the sleeve 31 and are arranged at intervals, and the worm 36 is installed between the two mounting seats 33; the mounting shaft 37 passes through one mounting seat 33, the worm 36 and the second mounting seat 33, and its two ends are respectively connected to the first connecting rod 13 and the second connecting rod 14, and the center line of the mounting shaft 37 is perpendicular to the center line of the rotating shaft 25.

[0056] like Figure 7-9The worm 36 and the mounting seat 33 are driven by the pawl 332 and the ratchet 335. Specifically, the mounting seat 33 includes a seat body 331 and a ratchet 335, a pawl 332, a first coil spring 333, and a second coil spring 334 installed in the seat body 331. The seat body 331 has an inner side wall facing the turbine 21, and a notch is provided in the inner side wall for the ratchet 335 to be placed. The ratchet 335 is fixed to one end of the turbine 21; the pawl 332 is swingably installed in the seat body 331 through a ratchet shaft and is located on one side of the ratchet 335. The pawl 332 has a first side and a second side that are symmetrically arranged. The end of the first side close to the ratchet 335 is provided with a first ratchet tooth 3323 for pushing the ratchet 335 to rotate in a positive direction, and the end of the second side close to the ratchet 335 is provided with a second ratchet tooth 3324 for pushing the ratchet 335 to rotate in a reverse direction; the first coil spring 333 abuts against the first side of the pawl 332, and the second coil spring 334 abuts against the second side of the pawl 332. The first coil spring 333 and the second coil spring 334 are used to reset the pawl 332.

[0057] Continuing from the above, a first protrusion 3321 is provided at one end of the first side of the pawl 332 away from the ratchet 335, and a second protrusion 3322 is provided at one end of the second side of the pawl 332 away from the ratchet 335, and the first protrusion 3321 and the second protrusion 3322 form an angle; the first coil spring 333 abuts against the first protrusion 3321, and the second coil spring 334 abuts against the second protrusion 3322.

The extension direction of the lever 34 is perpendicular to the center line of the rotating rod 35. The lever 34 passes through the inner wall of the first mounting seat 33 and abuts against the pawl 332 to push the pawl 332 to rotate. Under normal circumstances, that is, the rotating rod 35 is not rotated, the lever 34 is located between the first protrusion 3321 and the second protrusion 3322. Due to the elastic force of the coil spring, the pawl 332 and the ratchet 335 are staggered, and the swing of the operating lever does not affect the rotation of the worm 36; when the rotating rod 35 is rotated counterclockwise, the lever 34 presses the first protrusion 3321 so that the first ratchet tooth 3323 abuts against the tooth groove of the ratchet 335, and the swinging operating lever can make the ratchet 335 rotate in the positive direction; when the rotating rod 35 is rotated clockwise, the lever 34 presses the second protrusion 3322 so that the second ratchet tooth 3324 abuts against the tooth groove of the ratchet 335, and the swinging operating lever can make the ratchet 335 rotate in the reverse direction. In this embodiment, the two mounting seats 33 are arranged as a symmetrical structure, the first extension parts of the two pawls 332 are connected, and the second extension parts of the two pawls 332 are connected, which is beneficial to structural balance and stability. In other examples, matching pawls 332 and ratchet wheels 335 may be arranged in only one mounting seat 33.

[0064] 2. Second driving gear braking state:

[0065] refer to Figure 11-12 , pull up the handle 43, the operating line 47 pulls the toggle member backward to move the clutch 24 backward, at this time the turbine 21 is synchronized with the second drive gear 23, and the first drive gear 22 is locked; rotate the handle 43 counterclockwise, the lever 34 presses the first protrusion 3321 of the pawl 332, so that the first ratchet tooth 3323 engages the ratchet wheel 335, and the operating lever is pulled back and forth, and the second drive gear 23 rotates forward; rotate the handle 43 clockwise, the lever 34 presses the second protrusion 3322 of the pawl 332, so that the second ratchet tooth 3324 engages the ratchet wheel 335, and the operating lever is pulled back and forth, and the second drive gear 23 rotates reversely.

[0066] like Figure 15-17 ,The specific method of applying the control mechanism to the lateral moving device is as follows:
