The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1 to 8, an embodiment of the present invention provides an electronic apparatus including an apparatus housing 100, a flexible screen 200, and a driving device 300.
The device housing 100 is a basic component of the electronic device, and the device housing 100 can provide a mounting base for other component components of the electronic device, and meanwhile, the device housing 100 can also protect the other component components of the electronic device. The flexible screen 200 is a display member of an electronic device, and the flexible screen 200 can be bent or wound so that the electronic device can have an expanded state in which a display area is large, visual experience of a user can be improved, and a contracted state in which the display area is small, but the occupied space can be reduced, and the electronic device is convenient to store. The driving device 300 is a structural member that drives the flexible screen 200 to perform state switching, and in particular, the driving device 300 may drive the flexible screen 200 to switch between an expanded state and a contracted state.
The driving device 300 comprises a driving gear 310, a first driving rack 320 and a second driving rack 330, wherein the first driving rack 320 and the second driving rack 330 are meshed with the driving gear 310, the first driving rack 320 is positioned on a first side of the driving gear 310, the second driving rack 330 is positioned on a second side of the driving gear 310, and the first side and the second side are arranged opposite to each other. The first and second driving racks 320 and 330 are engaged with the driving gear 310 such that the driving gear 310 rotates to simultaneously drive the first and second driving racks 320 and 330. The first driving rack 320 is located on a first side of the driving gear 310, and the second driving rack 330 is located on a second side of the driving gear 310, where the first side and the second side are opposite to each other, so that the driving gear 310 can simultaneously drive the first driving rack 320 and the second driving rack 330 to move in opposite directions.
Thus, by the cooperation of the driving gear 310, the first driving rack 320 and the second driving rack 330, and the above arrangement, it is possible to realize that the driving gear 310 simultaneously drives the first driving rack 320 and the second driving rack 330 to move in opposite directions, and further drives both ends of the flexible screen 200 to move in opposite directions.
The apparatus housing 100 includes a first housing portion 110 and a second housing portion 120, the first housing portion 110 and the second housing portion 120 are relatively movable, the driving device 300 is disposed within the apparatus housing 100, and the first driving rack 320 is connected to the first housing portion 110.
The first housing portion 110 and the second housing portion 120 may be relatively moved, so that the first housing portion 110 and the second housing portion 120 may be relatively close to or relatively far away from each other, and in the case that the first housing portion 110 and the second housing portion 120 are relatively close to each other, a distance from an end of the first housing portion 110 far away from the second housing portion 120 to an end of the second housing portion 120 far away from the first housing portion 110 is gradually reduced, and the flexible screen 200 is disposed on the first housing portion 110 and the second housing portion 120, so that a display area of the flexible screen 200 is also gradually reduced, and the electronic device may be switched to a contracted state.
In the case where the first housing portion 110 is relatively distant from the second housing portion 120, the distance from the end of the first housing portion 110 distant from the second housing portion 120 to the end of the second housing portion 120 distant from the first housing portion 110 gradually increases, and the flexible screen 200 is provided to the first housing portion 110 and the second housing portion 120, and thus the display area of the flexible screen 200 also gradually increases, and the electronic apparatus can be switched to the unfolded state.
The movement of one of the first housing portion 110 and the second housing portion 120 may achieve the relative approaching or moving away of the first housing portion 110 and the second housing portion 120, although the first housing portion 110 and the second housing portion 120 may also be moved simultaneously to achieve the relative approaching or moving away of the first housing portion 110 and the second housing portion 120.
In the case where the first housing part 110 moves and the second housing part 120 does not move, the first driving rack 320 is connected to the first housing part 110, and the first housing part 110 can be driven to move by the first driving rack 320. The second housing part 120 does not move and the second housing part 120 is not provided with a driving structure. The second driving rack 330 may be movably matched with the second housing portion 120, that is, the second driving rack 330 and the second housing portion 120 do not affect each other, and the second driving rack 330 is connected to the second end of the flexible screen 200 to drive the second end of the flexible screen 200 to move. The first driving rack 320 and the second driving rack 330 may be meshed with the same driving gear 310, and the driving gear 310 drives the first driving rack 320 and the second driving rack 330 to move synchronously, so that the moving speeds of the first driving rack 320 and the second driving rack 330 are the same, and the moving speeds of the two ends of the flexible screen 200 are the same, so that the flexible screen 200 is prevented from being pulled.
In the case where both the first housing part 110 and the second housing part 120 are moved, the first driving rack 320 is connected to the first housing part 110, and the first housing part 110 can be moved by the first driving rack 320. The second housing portion 120 may be connected to a third driving rack, and the second housing portion 120 may be driven to move by the third driving rack. The second driving rack 330 is connected to the second end of the flexible screen 200, and the second end of the flexible screen 200 is driven to move by the second driving rack 330. The second drive rack 330 may be in a moving engagement with the second housing portion 120, i.e., the second drive rack 330 does not interact with the second housing portion 120. In this case, parameters of the first driving rack 320, the second driving rack 330, the third driving rack and the driving gear 310 need to be set, so that the moving speed of the second driving rack 330 is equal to the sum of the moving speeds of the first driving rack 320 and the third driving rack, ensuring that the flexible screen 200 is unfolded or contracted to meet the length required for the first housing part 110 and the second housing part 120 to move simultaneously, and avoiding pulling the flexible screen 200.
For example, the driving gear 310 may be provided with multiple sections, the radius of the multiple sections or the parameters of teeth on the multiple sections are different, and different sections of the driving gear 310 may be meshed with the first driving rack 320, the second driving rack 330 and the third driving rack respectively, so that the driving gear 310 drives the first driving rack 320, the second driving rack 330 and the third driving rack. Of course, the first and third drive racks 320 and 310 may be engaged with the same drive gear 310 or the same section of the drive gear 310 such that the speed of movement of the first and second housing portions 110 and 120 is the same. The second drive rack 330 is engaged with the other section of the drive gear 310, and the second drive rack 330 moves at a greater speed than the first drive rack 320 and the third drive rack.
Since the first housing part 110 and the second housing part 120 move at the same time, the speed of expanding or contracting the electronic device can be increased.
The flexible screen 200 is disposed on the first housing portion 110 and the second housing portion 120, and a first end of the flexible screen 200 is connected to an end of the first housing portion 110 away from the second housing portion 120, and a second end of the flexible screen 200 bypasses an end of the second housing portion 120 away from the first housing portion 110 and is connected to the second driving rack 330. When the driving gear 310 rotates, the driving gear 310 drives the first driving rack 320 to move, the first driving rack 320 drives the first housing portion 110 to move, the first housing portion 110 can drive the first end of the flexible screen 200 to move, meanwhile, the driving gear 310 drives the second driving rack 330 to move, the second driving rack 330 drives the second end of the flexible screen 200 to move, and the direction of the movement of the first end and the second end of the flexible screen 200 is opposite, so that the flexible screen 200 can be switched between the expanded state and the contracted state.
The first end of the flexible screen 200 to the end of the second housing portion 120 remote from the first housing portion 110 may serve as a display surface of the flexible screen 200.
When the first driving rack 320 moves towards the end far away from the first housing part 110 and away from the second housing part 120, the first end of the flexible screen 200 is driven to move towards the end far away from the first housing part 110 and away from the second housing part 120, meanwhile, the second driving rack 330 moves towards the end far away from the first housing part 110 and close to the second housing part 120, the second end of the flexible screen 200 is driven to move towards the end far away from the first housing part 110 and close to the second housing part 120, the area of the display surface of the flexible screen 200 is increased, that is, the display area is increased, and the display surface is gradually switched to the unfolding state.
When the first driving rack 320 moves towards the end, away from the first housing part 110, of the second housing part 120, the first end of the flexible screen 200 is driven to move towards the end, away from the first housing part 110, of the second housing part 120, and simultaneously, the second driving rack 330 moves towards the end, away from the first housing part 110, of the second housing part 120, the second end of the flexible screen 200 is driven to move towards the end, away from the first housing part 110, of the second housing part 120, and the area of the display surface of the flexible screen 200 is reduced, namely the display area is reduced, so that the display surface is gradually switched to a contracted state.
With the electronic device of the embodiment of the present application, the first driving rack 320 may drive the first end of the flexible screen 200 through the first housing portion 110, and the second driving rack 330 may drive the second end of the flexible screen 200, so that both ends of the flexible screen 200 have driving structures, the flexible screen 200 does not need the elastic member to apply the pre-tightening force, and the flexible screen 200 is prevented from being stretched to be deformed by the pre-tightening force, thereby prolonging the service life of the flexible screen 200.
In addition, the first driving rack 320 and the second driving rack 330 are simultaneously meshed with two sides of the driving gear 310, so that the driving gear 310 can simultaneously drive the first driving rack 320 and the second driving rack 330 to move so as to simultaneously drive the first end and the second end of the flexible screen 200, and the same driving gear 310 can simultaneously drive two ends of the flexible screen 200 through the two driving racks, so that the displacement amounts of the two ends of the flexible screen 200 are consistent, and the flexible screen 200 stretches and contracts stably; and the second end of the flexible screen 200 bypasses the end of the second housing portion 120 far from the first housing portion 110 and is connected with the second driving rack 330, and the flexible screen 200 after bypassing the end of the second housing portion 120 far from the first housing portion 110 is still in a flat state, so that the flexible screen 200 can be prevented from being wound on a reel, and further, the deformation of the flexible screen 200 for a long time and at a large angle can be avoided, and the service life of the flexible screen 200 can be further prolonged.
