Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 5, an embodiment of the invention discloses a driving mechanism, and the disclosed driving mechanism is suitable for an electronic device. The electronic device comprises a driven module 100, a device housing (i.e. the housing described in the background of the invention) 200 and the driving mechanism, wherein the driving mechanism is disposed in the device housing 200, the driving mechanism is connected to the driven module 100, and the driving mechanism is used for driving the driven module 100 to move, so as to adjust the working position or the working orientation of the driven module 100. In one embodiment, the device housing 200 has a housing cavity 210 and a through hole 220, the through hole 220 is communicated with the housing cavity 210, and the driven module 100 can extend out of the device housing 200 or retract into the housing cavity 210 through the through hole 220.
The driving mechanism disclosed by the embodiment of the invention comprises a base 310, a driving motor 320, a first transmission mechanism 330, a second transmission mechanism 340, a magnetic assembly 350 and a third transmission mechanism 360.
The base 310 is a basic component of the driving mechanism, the base 310 can provide a mounting base for other components of the driving mechanism, the driving motor 320, the first transmission mechanism 330, the second transmission mechanism 340 and the magnetic assembly 350 are disposed on the base 310, a part of the third transmission mechanism 360 is disposed on the base 310, and another part of the third transmission mechanism 360 is disposed on the device housing 200.
In the embodiment of the present invention, the base 310 is movably provided to the apparatus housing 200, so that the position change on the apparatus housing 200 can be achieved by the movement. In particular, the base 310 may be slidably disposed within the housing interior 210 of the device housing 200 such that the position within the housing interior 210 can be changed by sliding.
The first transmission mechanism 330 includes a first transmission member 332, and the first transmission member 332 is movably disposed on the base 310 and can move between a first position and a second position. The magnetic assembly 350 drives the first transmission member 332 to move, and in particular, the magnetic assembly 350 drives the first transmission member 332 to move between the first position and the second position by applying a magnetic force to the first transmission member 332. The driving motor 320 is drivingly connected to the first transmission member 332, and the driving motor 320 can drive the first transmission member 332 to rotate. In a normal case, the driving motor 320 may drive the first transmission member 332 through the speed reducer 370, and the speed reducer 370 may better adjust the rotation speed of the first transmission member 332.
When the first transmission member 332 moves to the first position, the first transmission member 332 is connected to the driven module 100 through the second transmission mechanism 340, and can drive the driven module 100 to rotate. Specifically, the first transmission member 332 is connected with the second transmission mechanism 340 in a transmission manner, and since the driven module 100 is connected with the second transmission mechanism 340, the driven module 100 can be driven to rotate by the second transmission mechanism 340 in the rotation process of the first transmission member 332, and finally the orientation of the driven module 100 can be changed, so that the purpose of adjusting the working angle of the driven module 100 is achieved.
When the first transmission member 332 moves to the second position, the first transmission member 332 is connected to the base 310 through the third transmission mechanism 360, and can drive the base 310 to move the driven module 100 in the equipment housing 200. Specifically, the first transmission member 332 is in transmission connection with the third transmission mechanism 360, and since the third transmission mechanism 360 is partially disposed on the base 310 and the other part is disposed in the housing inner cavity 210, the base 310 can be driven by the third transmission mechanism 360 to move in the housing inner cavity 210 during the rotation process of the first transmission member 332. The movement of the base 310 can drive the driving motor 320, the first transmission mechanism 330, the second transmission mechanism 340 and the magnetic assembly 350 to move together, so that the second transmission mechanism 340 can drive the driven module 100 to move, and the driven module 100 can extend out of the equipment housing 200 or retract into the equipment housing 200 through the through hole 220. In the embodiment of the present invention, the movement of the driven module 100 is a linear movement.
The working process of the driving mechanism disclosed by the embodiment of the invention is as follows: under the condition that the magnetic assembly 350 drives the first transmission member 332 to move to the second position, the first transmission member 332 is connected to the base 310 through the third transmission mechanism 360, and the driving motor 320 drives the first transmission member 332 to rotate, so that the base 310 drives the driven module 100 to extend out of the device housing 200 through the through hole 220 by the third transmission mechanism 360, and finally the driven module 100 can work. In the case that the driven module 100 extends out of the equipment housing 200, if the orientation of the driven module 100 needs to be adjusted, the first transmission member 332 needs to be driven to move from the second position to the first position through the magnetic assembly 350, in this case, the first transmission member 332 is separated from the third transmission mechanism 360, the first transmission member 332 is in transmission connection with the second transmission mechanism 340, and the driven module 100 stops moving and rotates, so that the adjustment of the working angle is achieved. After the driven module 100 finishes working, the first transmission member 332 is engaged with the second transmission mechanism 340, so that the driven module 100 is restored to a retractable state, and then the magnetic assembly 350 drives the first transmission member 332 to move from the first position to the second position, so that the first transmission member 332 is engaged with the third transmission mechanism 360 again, so that the driving base 310 drives the driven module 100 to retract into the equipment housing 200 through the through hole 220 via the second transmission mechanism 340, thereby achieving the purpose of hiding in the equipment housing 200.
In a specific operation process, the rotation direction of the driving motor 320 can be adjusted, so as to realize the rotation switching in two directions or the movement switching in two directions of the driven module 100.
As can be seen from the above working process, the driving mechanism disclosed in the embodiment of the present invention improves the structure of the driving mechanism of the electronic device in the prior art, such that the first transmission member 332, the second transmission mechanism 340 and the third transmission mechanism 360 form a clutch mechanism, and by changing the position of the first transmission member 332, the first transmission member 332 can be in transmission fit with the second transmission mechanism 340 at the first position and can be in transmission fit with the third transmission mechanism 360 at the second position, and the first transmission member 332 can transmit the power of the driving motor 320 to different transmission mechanisms at different positions, so as to enable the driven module 100 to realize one of movement and rotation, in this case, the driving mechanism can realize the driving of the driven module 100 by configuring one driving motor 320. Compared with the prior art in which a large number of driving motors need to be configured, the driving mechanism disclosed in the embodiment of the present invention can certainly reduce the number of driving motors 320, and finally simplify the structure of the driving mechanism, and can also reduce the occupation of the internal space of the device housing 200.
In the embodiment of the present invention, the transmission between the first transmission member 332 and the second transmission mechanism 340 and between the first transmission member 332 and the third transmission mechanism 360 may be realized by a belt transmission mechanism, a chain transmission mechanism, or a gear combination. For example, in the case of a transmission by a belt transmission, the first transmission part 332 can be in transmission connection with the second transmission part 340 via the first belt transmission at a first position and with the third transmission part 360 via the second belt transmission at a second position by its own movement. Specifically, the first transmission member 332 may be in transmission connection with the pulley of the first belt transmission mechanism at a first position, and be separated from the pulley of the second belt transmission mechanism, in which case the first transmission member 332 can drive the first belt transmission mechanism to operate, so as to drive the second transmission mechanism 340 to operate. The first transmission member 332 can be in transmission connection with the pulley of the second belt transmission mechanism at the second position and be separated from the pulley of the first belt transmission mechanism, in which case the first transmission member 332 can drive the second belt transmission mechanism to operate, so as to drive the third transmission mechanism 360 to operate, and finally drive the base 310 to move.
As described above, the first transmission member 332 is movable on the base 310 so as to move between the first position and the second position. There are various ways of engaging the first transmission member 332 to move. Optionally, the first transmission mechanism 330 may further include a first rotating shaft 331, the first rotating shaft 331 is movably disposed on the base 310 and connected to the driving motor 320, and the movement of the first rotating shaft 331 enables the first transmission member 332 to move between the first position and the second position. The first transmission member 332 is disposed on the first rotating shaft 331 and can move along with the first rotating shaft 331. Specifically, the first transmission member 332 is fixed on the first rotation shaft 331. The driving motor 320 is in transmission connection with the first rotating shaft 331, and the driving motor 320 drives the first rotating shaft 331 to rotate, so as to drive the first transmission member 332 to rotate, thereby realizing power transmission. Specifically, the first rotating shaft 331 is in sliding fit with the power output shaft of the driving motor 320 in the axial direction of the power output shaft, and is in limited fit in the circumferential direction of the power output shaft, so that the power output shaft of the driving motor 320 can only output power to the first rotating shaft 331 in the rotating direction of the power output shaft.
In a specific embodiment, the first rotating shaft 331 may be a hollow shaft, the first rotating shaft 331 may be sleeved on the power output shaft, the first rotating shaft 331 and the power output shaft are slidably engaged in an axial direction of the power output shaft, and the first rotating shaft 331 may rotate along with the power output shaft. Specifically, the first rotating shaft 331 and the power output shaft may be spline-fitted, so as to achieve the above-mentioned fitting relationship. Of course, it may be: the power output shaft is a hollow shaft, the first rotating shaft 331 is inserted into the power output shaft, and the first rotating shaft 331 and the power output shaft can also realize power transmission through spline fit. The above-mentioned assembly manner of the sleeve joint can ensure that the first rotating shaft 331 can easily form a movable assembly manner, so as to drive the first transmission member 332 to move.
Of course, in another specific embodiment, the driving motor 320 includes a power output shaft, the first transmission member 332 is sleeved on the power output shaft, the first transmission member 332 is movable between a first position and a second position along the power output shaft, and the first transmission member 332 is configured to transmit along with the power output shaft. Specifically, the first transmission member 332 and the power output shaft may be connected by a spline fit. The structure is simple and convenient to assemble.
In an embodiment of the present invention, the magnetic assembly 350 may include a first electromagnetic member 351 and a second electromagnetic member 352 spaced apart from each other, and the first transmission member 332 is located between the first electromagnetic member 351 and the second electromagnetic member 352. When the first electromagnetic element 351 is energized and the second electromagnetic element 352 is de-energized, the first electromagnetic element 351 drives the first transmission element 332 to move from the first position to the second position by magnetic force, specifically, the first electromagnetic element 351 may generate magnetic attraction force on the first transmission element 332, so as to attract and move the first transmission element 332 from the first position to the second position. In the case that the first electromagnetic member 351 is powered off and the second electromagnetic member 352 is powered on, the second electromagnetic member 352 drives the first transmission member 332 to move from the second position to the first position by magnetic force, and specifically, the second electromagnetic member 352 may apply magnetic attraction to the first transmission member 332 so as to drive the first transmission member 332 from the second position to the first position. The magnetic assembly 350 can be realized by controlling the power-on states of the first electromagnetic part 351 and the second electromagnetic part 352 in the working process, and the control is simple and efficient. Specifically, the first and second electromagnetic members 351 and 352 may be fixed to the base 310. Of course, the first and second electromagnetic members 351 and 352 may be fixed to the power output shaft of the driving motor 320.
Of course, the first electromagnetic member 351 and the second electromagnetic member 352 may both exert a magnetic repulsive force on the first transmission member 332, so as to switch the movement of the first transmission member 332 between the first position and the second position. Of course, whether a magnetic repulsive force or a magnetic attractive force is applied, the same driving purpose can be achieved by adjusting the relative position relationship between the first electromagnetic member 351 and the second electromagnetic member 352 relative to the first transmission member 332.
The magnetic assembly 350 according to the embodiment of the present invention may have various structures, and is not limited to include the first electromagnetic member 351 and the second electromagnetic member 352. For example, the magnetic assembly 350 may include an electromagnetic member and an elastic member, the electromagnetic member can drive the first transmission member 332 to overcome the elastic force of the elastic member in the power-on state, so as to move from the first position to the second position, in the power-off state of the electromagnetic member, the magnetic force of the electromagnetic member disappears, and the elastic member recovers its deformation under the elastic restoring force, so as to drive the first transmission member 332 to move from the second position to the first position by the elastic force. In particular, the elastic member may be a spring.
In a specific embodiment, the first transmission member 332 may be slidably disposed on the power output shaft of the driving motor 320, the first transmission member 332 may be in power transmission engagement with the power output shaft through spline engagement, the elastic member may be sleeved on the power output shaft of the driving motor 320, the elastic member may be located on one side of the first transmission member 332, one end of the elastic member is in elastic contact with one end of the first transmission member 332 and may apply an elastic force to the first transmission member 332, and the electromagnetic member may be disposed on the other side of the first transmission member 332.

When the first transmission member 332 moves to the first position, the second stopper 334 is in stopper contact with the second electromagnetic member 352, so that excessive movement of the first transmission member 332 can be avoided.
In the embodiment of the present invention, the driving motor 320 includes a power output shaft, and specifically, the first electromagnetic member 351 may be a first annular electromagnetic member fixed on the power output shaft, the second electromagnetic member 352 may be a second annular electromagnetic member fixed on the power output shaft, the first limiting portion 333 may be a first annular limiting portion, and the second limiting portion 334 may be a second annular limiting portion, where the first annular electromagnetic member is in limiting contact with the first annular limiting portion when the first transmission member 332 is in the second position, and the second annular electromagnetic member is in limiting contact with the second annular limiting portion when the first transmission member 332 is in the first position. The spacing in more positions can be realized through the spacing cooperation, and then the spacing which is stable can be realized.
