The transmission mechanism 32 and the transmission mechanism 32 are respectively connected with the driving mechanism 31 and the driven component 10, and the driving mechanism 31 drives the driven component 10 to move and rotate in steps through the transmission mechanism 32.

In this embodiment, the driving assembly 30 includes a driving mechanism 31 and a transmission mechanism 32, the driving mechanism 31 is connected to the transmission mechanism 32, and the transmission mechanism 32 is also connected to the driven component 10. The driving mechanism 31 provides driving force to the transmission mechanism 32, and the driven component 10 is driven to move and rotate in steps through the transmission mechanism 32. The driving mechanism 31 may be an electric driving mechanism 31 or a mechanical driving mechanism. The electric driving mechanism 31 may be a driving motor 311, and the mechanical driving mechanism 31 may be a manual transmission mechanism 32. The user can manually twist the handle to drive the output shaft to rotate . Other equipment capable of providing power can be applied to this embodiment without limitation.

Specifically, the driving mechanism 31 may be a driving motor 311, and the transmission mechanism 32 may include:

Screw 321, the central axis of the screw 321 is oriented along the axis of the opening 21, the first end of the screw 321 is connected to the drive motor 311 to be driven to rotate by the drive motor 311, the screw 321 includes a threaded section and a non-threaded section, the threaded section Adjacent to the first end, a first gear 323 is provided on the non-threaded section;

The screw sleeve 322 is connected with the driven component 10, and the screw sleeve 322 is threadedly matched with the screw 321 to drive the driven component 10 to move;

The second gear 324 and the second gear 324 are connected to the driven component 10. When the screw sleeve 322 moves to the non-threaded section along the screw 321, the second gear 324 meshes with the first gear 323 to drive the driven component 10 to rotate.

In this embodiment, the driving mechanism 31 is a driving motor 311, and the output shaft of the driving motor 311 is connected to the transmission mechanism 32. The driving motor 311 can receive the control signal sent by the main board of the electronic device through the driving circuit board 312, and control the rotation of the output shaft according to the control signal to drive the transmission mechanism 32 to rotate.

Through the contact between the ball in the screw sleeve 322 and the threaded section of the screw 321, the rotary motion of the screw 321 is converted into the linear motion of the screw sleeve 322, or the torque is converted into an axial repeated force. The friction is small, and it has the characteristics of high precision, reversibility and high efficiency. Therefore, selecting the screw 321 as a ball screw can improve the motion accuracy and stability of the driven component 10, and is efficient and convenient.

Optionally, the first gear 323 and the second gear 324 are both helical gears.

The helical gear includes a cylindrical shaft and teeth, and the teeth form a certain angle with the axis of the cylinder. When a pair of parallel-axis helical cylindrical gears mesh, the tooth profile of the helical gear gradually enters and disengages. The length of the contact line of the helical gear tooth profile gradually increases from zero, and then gradually shortens until it is out of contact. When the front end surface is out of mesh, the rear end surface of the tooth profile is still meshing, and the load is not suddenly added or removed in the tooth width direction. The meshing process is longer than that of a spur gear. At the same time, the number of meshed gear pairs is also higher than that of a straight gear. There are many gears, which makes the coincidence degree larger. Therefore, the first gear 323 and the second gear 324 can be selected as helical gears that mesh with each other, so that the meshing is more stable, the bearing capacity is stronger, and the noise and impact are smaller.

Since the driven component 10 is connected to the screw sleeve 322, the driven component 10 also moves toward the direction close to the opening 21 accordingly.

When the screw sleeve 322 moves along the threaded section of the screw 321 to the non-threaded section, the screw sleeve 322 and the screw 321 are no longer threadedly engaged, and the screw sleeve 322 no longer moves linearly along the screw 321. At this time, the driven component 10 has protruded from the opening 21 of the housing 20, the non-threaded section is provided with a first gear 323, the first gear 323 is driven to rotate by the lead screw 321, the first gear 323 meshes with the second gear 324 for transmission. The second gear 324 is connected to the driven component 10, and the second gear 324 drives the driven component 10 to rotate, so that the driven component 10 can rotate after extending out of the opening 21.

In this embodiment, the principle that the screw 321 and the screw sleeve 322 cooperate to convert the direction of movement is used, and the screw 321 is driven to rotate through the drive motor 311, and the screw sleeve 322 and the first gear 323 and the second gear 324 meshing with each other are used together. , The step-by-step movement and rotation of the driven component 10 can be realized.

Specifically, the elastic reset member 327 can be sleeved on the lead screw 321, and one end of the elastic reset member 327 is connected to the first gear 323.

In this way, when the screw sleeve 322 moves along the threaded section of the screw 321 to be non-threaded, the first gear 323 is pushed close to the second gear 324 by the elastic reset member 327, so that the first gear 323 can mesh with the second gear 324, The screw cover 322 stops moving, that is, the moving state of the driven component 10 is pushed to quickly switch to the rotating state. When the screw 321 rotates in the reverse direction to drive the driven component 10 to rotate and return to the initial position, the second gear 324 and the first gear 323 are disengaged from the meshed state, the first gear 323 is disengaged from the second gear 324, and the screw is pushed by the elastic return member 327 The sleeve 322 slides from the non-threaded section to the threaded section, so that the rotating state of the driven component 10 can be quickly switched to the moving state, which ensures the stability and continuity of the driving process.
