[0016] This embodiment provides a manual / automatic control switching device, including a manual control shaft 2, a linkage mechanism 3, a switching mechanism 1, and a drive motor 4. The linkage mechanism includes an active mechanism and a driven mechanism. The active mechanism drives the driven mechanism, which is fixedly connected to the manual control shaft. The active mechanism is connected to the drive motor 4. The output end of the drive motor has a first slot, and the active mechanism has a second slot. The switching device includes a latch. When the first and second slots correspond, the latch inserts into them, fixing the active mechanism to the drive motor 4. The drive motor 4 rotates, causing the active mechanism to move, which in turn drives the driven mechanism, thus achieving automatic control of the manual control shaft. When the latch disengages from the first and second slots, manual control of the manual control shaft is achieved. The linkage mechanism can employ gear transmission, belt transmission, sprocket transmission, etc. When using belt drive, the driving mechanism is a driving pulley, and the driven mechanism is a driven pulley. A belt is fitted around the outer sides of both the driving and driven pulleys, and the driving and driven pulleys are driven by the belt. The driven pulley is fixedly fitted around the outside of the manual control shaft, and the driving pulley is fitted around the output end of the drive motor. A second groove is provided on the inner ring of the driving pulley. A housing 2 is provided outside the linkage mechanism to cover the gears, pulleys, and other linkage components, protecting the structure during operation.

[0017] like Figures 1 to 5 As shown in the illustration, this embodiment describes a manual control and automatic control switching device, with the linkage mechanism employing gear transmission. The driving mechanism is a driving gear 31, and the driven mechanism is a driven gear 32, with the driving gear 31 meshing with the driven gear 32.

[0018] A drive motor 4 is mounted on a support frame 6. The output shaft of the drive motor is fixedly connected to a coupling 5. The coupling includes a connecting part 51 fixedly connected to the drive motor and a mounting shaft 52 fixedly connected to the connecting part. The mounting shaft extends from the end face of the connecting part in a direction away from the motor. The connecting part of the coupling is provided with a limiting part 511, a limiting groove 512, and a first retaining groove 513. The limiting part 511 and the limiting groove 512 are circumferentially arranged, and the first retaining groove 513 extends axially. A drive gear 31 is sleeved on the outside of the coupling and is located between the limiting part 511 and the limiting groove 512. A limiting spring 53 is inserted in the limiting groove. The drive gear 31 is axially positioned with the coupling 5 through the limiting part 511 and the limiting spring 53. The drive gear is sleeved on the outside of the first retaining groove 513, and a second retaining groove 311 is provided on the inner ring of the drive gear.

[0019] like Figure 6As shown, the latch includes a mounting portion 11 and a pin 12 fixed to the mounting portion. The mounting portion 11 has an axially extending through hole 13. The pin 12 extends axially outward from the outer periphery of the end face of the mounting portion. When the latch is inserted into the first slot 513 and the second slot 311, the mounting portion 11 of the latch is sleeved on the mounting shaft 52, and the pin 12 is inserted into the first slot 513 and the second slot 311. One end of the pin that is inserted into the first slot 513 and the second slot 311 is arc-shaped to facilitate the insertion of the pin into the first slot 513 and the second slot 311.

[0020] When the latch is simultaneously inserted into the first slot of the coupling and the second slot of the drive gear, the drive motor is energized and rotates, which in turn drives the drive gear. The drive gear drives the driven gear, which in turn drives the manual control shaft to rotate, thus achieving automatic control. When the latch disengages from the first and second slots, the output shaft of the drive motor rotates relative to the drive gear. The rotation generated by the energized drive motor cannot drive the drive gear. When the motor is jammed, the manual control shaft will not be restricted by the drive motor shaft, and the gear will not be jammed due to the motor jamming. Normal operation can be achieved manually.
