In the electronic device provided by the above-mentioned embodiment, the pushing and rotation of the driven component can be realized by only one set of driving components, and there is no need to set two different transmission components, so there is no need to control two different transmission components separately. The transmission assembly of the disclosed embodiment has a simple structure, takes up less space, and has high control sensitivity.

In a specific embodiment, as shown in FIGS. 1 to 8, the driving assembly 30 may include:

The driving mechanism 31 is provided in the housing 20 and connected to the housing 20; and

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 a distributed manner 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 31, the electric driving mechanism 31 may be a driving motor, 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, and the transmission mechanism 32 may include:

Screw 321, the central axis of the screw 321 is parallel to the axis of the opening 21, the first end of the screw 321 is connected with the drive motor to be driven by the drive motor to rotate, the screw 321 includes a threaded section and a non-threaded section, the threaded section is adjacent to the first One end

The lead screw 321 sets, the lead screw 321 sets are connected with the driven part 10, the lead screw 321 sets and the lead screw 321 are threadedly matched to drive the driven part 10 to move;

The steering assembly 323, the steering assembly 323 are respectively connected with the lead screw 321 and the driven part 10, when the lead screw 321 is moved to the non-threaded section along the lead screw 321, the steering assembly 323 and the lead screw 321 are rotationally connected to drive the driven part 10 rotate around the axis of rotation.

In this embodiment, the drive mechanism 31 is a drive motor, and the output shaft of the drive motor is connected to the transmission mechanism 32. The drive motor can receive the control signal sent by the main board of the electronic device through the drive circuit board, and control the rotation of the output shaft according to the control signal to drive the transmission mechanism 32 to rotate. The transmission mechanism 32 includes a screw 321, a screw 321 sleeve, and a steering assembly 323. The screw 321 is sleeved on the screw 321, and the central axis of the screw 321 is parallel to the axis of the opening 21. The steering assembly 323 is connected to the screw 321. The sleeve is connected with the driven component 10, and the screw 321 sleeve pushes the driven component 10 to rotate through the steering assembly 323.

Specifically, the screw 321 includes a threaded section and a non-threaded section. The threaded section is provided with threads, and the non-threaded section is not provided with threads, and is generally a smooth curved surface. Generally, the length of the threaded section on the lead screw 321 is greater than the length of the non-threaded section.

Optionally, the screw 321 is a ball screw 321, and the ball screw 321 is provided with balls in rolling contact with the ball screw 321 in the sleeve of the screw 321. Through the contact between the ball in the screw 321 sleeve and the threaded section of the screw 321, the rotary motion of the screw 321 is converted into the linear motion of the screw 321, 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 ball screw 321 as the ball screw 321 can improve the movement accuracy and stability of the driven component 10, and is efficient and convenient.

Linear movement, that is, moving toward the direction close to the opening 21. Since the driven part 10 and the steering assembly 323 are connected to the lead screw 321, the driven part 10 and the steering assembly 323 also move toward the direction close to the opening 21.

The screw 321 sleeve moves along the threaded section of the screw 321 to the non-threaded section, the screw 321 sleeve and the screw 321 no longer threadedly fit, and the screw 321 sleeve no longer moves linearly along the screw 321. At this time, the steering assembly 323 and the driven component 10 have protruded from the opening 21 of the housing 20. The steering assembly 323 is rotatably connected with the lead screw 321. The steering assembly 323 rotates with the lead screw 321, and the steering assembly 323 takes the driven part 10 to rotate therewith, so that the driven part 10 can rotate after extending out of the opening 21.

The driving assembly 30 has a simple structure and sensitive control, which optimizes the control scheme of the driven component 10.

Optionally, the steering component 323 may include:

The first gear 324, the first gear 324 is arranged on the non-threaded section;

The sleeve rod 326, the first end of the sleeve rod 326 is connected to the lead screw 321, the second end of the sleeve rod 326 is provided with a worm gear 327, the sleeve rod 326 is provided with a second gear 325 that can mesh with the first gear 324, and the sleeve The rod 326 is approximately parallel to the lead screw 321;

Worm 328, the worm 328 is arranged at the end of the sleeve rod 326 away from the lead screw 321, the worm 328 is connected to the driven part 10, the worm 328 is meshed with the worm wheel 327, and the worm 328 is arranged substantially perpendicular to the moving direction of the driven part 10;

When the screw 321 sleeve moves along the screw 321 to the non-threaded section, the second gear 325 meshes with the first gear 324 and drives the sleeve 326 to rotate, and the worm gear 327 meshes with the worm 328 to drive the driven component 10 to rotate through the worm 328.

As shown in FIGS. 1 to 8, the steering assembly 323 includes a first gear 324, a second gear 325, a sleeve rod 326, a turbine and a worm 328, which cooperate to realize the movement and rotation of the driven component 10. Specifically, the first gear 324 is arranged on the non-threaded section of the lead screw 321, the sleeve rod 326 is approximately parallel to the lead screw 321, the first end of the sleeve rod 326 is connected to the lead screw 321, and the sleeve is provided with a second gear 325 , The first gear 324 and the second gear 325 can mesh with each other after contact. A worm 328 and a worm gear 327 are provided at one end of the sleeve 326 away from the screw 321. The worm 328 meshes with the worm gear 327. The worm gear 327 is connected to the driven component 10, and the moving direction of the driven component 10 is substantially perpendicular to the worm 328.

In this way, when the screw 321 sleeve moves along the threaded section of the screw 321 to the non-threaded section, the second gear 325 moves to the position of the first gear 324 and meshes with the first gear 324, and the second gear 325 drives the first gear 324 to rotate. The first gear 324 drives the sleeve rod 326 to rotate, the worm gear 327 at the end of the sleeve rod 326 drives the worm 328 to rotate, and the driven component 10 connected to the worm 328 rotates accordingly. In this way, with the help of the sleeve rod 326, the worm 328 and other structures to drive the driven component 10 to move and rotate, the moving distance of the driven component 10 can be increased, and the structure such as the screw 321 does not need to be located close to the opening 21 of the housing 20. , The installation control in the area near the opening 21 in the housing 20 is released, and the flexibility of assembly of the drive assembly 30 is improved.

Further, optionally, the first gear 324 and the second gear 325 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 324 and the second gear 325 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.

In another embodiment, the transmission mechanism 32 may further include:

Specifically, the elastic reset member 329 is sleeved on the sleeve rod 326;

When the screw 321 sleeve moves along the screw 321 to the non-threaded section, the elastic return member 329 abuts against the second gear 325.

Set the elastic reset piece 329 on the sleeve, so that when the screw 321 is moved along the screw 321, the elastic reset piece 329 is not squeezed and is in a free state, and the screw 321 is sleeved along the screw. When the rod 321 moves to the non-threaded section, the elastic return member 329 abuts against the second gear 325 and is continuously pressed by the second gear 325 to be elastically deformed, and the driven component 10 is switched from the pushing-out moving state to the rotating state. In order to restore the elastic deformation, the elastic reset member 329 reversely pushes the second gear 325 away from the first gear 324, thereby pushing the screw 321 sleeve to slide from the non-threaded section of the screw 321 to the threaded section, so that the screw 321 sleeve is connected to the threaded section. With cooperation, the driven component 10 is switched from the rotating state to the retracted moving state. The elastic reset member 329 pushes the driven component 10 to switch between the rotating state and the moving state, ensuring the stability and continuity of the driving process.

Wherein, the restoring member can be an elastic restoring member 329 which is a spring shown in FIGS. 3 to 8. Of course, the elastic restoring member 329 can also be other parts with elastic characteristics, which is not specifically limited in the present disclosure.
