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 12, an embodiment of the invention discloses an electronic device, which includes a housing 100, a reel 200, a driving mechanism 300, a flexible display 400, and a supporting portion 500.
The housing 100 is a basic component of the electronic device, and the housing 100 can provide a mounting base for other components (e.g., a motherboard, a battery, etc.) of the electronic device. The housing 100 defines an opening 110, and the opening 110 may be generally defined in a frame of the housing 100. The opening 110 may allow at least a portion of the flexible display 400 to pass therethrough, thereby enabling at least a portion of the flexible display 400 to enter and exit the housing 100.
The scroll 200 is rotatably disposed in the housing 100, the flexible display 400 is connected to the support 500, and the flexible display 400 and the support 500 can be wound around the scroll 200. Specifically, the reel 200 may rotate in a first rotation direction and a second rotation direction, and in the case where the reel 200 rotates in the first rotation direction, the flexible display 400 and the support 500 are wound around the reel 200 by the rotation of the reel 200; in the case where the reel 200 is rotated in the second rotation direction, the flexible display 400 and the support part 500 are unwound by the rotation of the reel 200. The first rotational direction is opposite to the second rotational direction.
The driving mechanism 300 is disposed in the housing 100, and the driving mechanism 300 is connected to the reel 200, and the driving mechanism 300 drives the flexible display 400 to retract into the housing 100 at least partially through the opening 110 or extend out of the housing 100 at least partially by driving the reel 200 to rotate. Specifically, the driving mechanism 300 may be a coil spring, a rotating motor, or the like, and the kind of the driving mechanism 300 is not limited in the embodiment of the present invention.
The supporting part 500 can be switched between a flexible state and a rigid state, and under the condition that the flexible display screen 400 is at least partially retracted into the casing 100, the supporting part 500 is in the flexible state, so that the flexible display screen 400 can be wound on the reel 200; under the condition that the flexible display screen 400 at least partially extends out of the housing 100, the supporting part 500 is in a rigid state, so that the supporting part 500 can play a role of supporting the flexible display screen 400, and a user can conveniently use the flexible display screen 400.
During the specific operation of the electronic device, when a user needs to use the flexible display 400, the driving mechanism 300 drives the roller 200 to rotate in the second rotation direction, so as to drive the flexible display 400 to at least partially extend out of the housing 100 through the opening 110, the supporting portion 500 is in a rigid state, the supporting portion 500 supports the flexible display 400 to display, and the user uses the flexible display 400. When the user does not use the flexible display 400 or the user uses up the flexible display 400, the driving mechanism 300 drives the roller 200 to rotate in the first rotation direction, so as to drive the flexible display 400 to retract at least partially into the housing 100 through the opening 110, and the support 500 is in a flexible state, thereby facilitating the flexible display 400 to be at least partially wound around the roller 200.
Specifically, the supporting part 500 is in a rigid state during the flexible display 400 at least partially protrudes out of the housing 100, or after the flexible display 400 at least partially protrudes out of the housing 100; the support part 500 is in a flexible state during the process that the flexible display 400 is at least partially ready to be retracted into the housing 100, or the flexible display 400 is at least partially retracted into the housing 100.
In the electronic device disclosed in the embodiment of the present invention, the driving mechanism 300 drives the flexible display 400 to retract into the housing 100 or extend out of the housing 100 at least partially through the opening 110 by driving the rotation of the reel 200, and the supporting portion 500 is in a flexible state under the condition that the flexible display 400 retracts into the housing 100 at least partially, so that the flexible display 400 can be wound around the reel 200; under the condition that the flexible display screen 400 at least partially extends out of the housing 100, the supporting part 500 is in a rigid state, so that the supporting part 500 can play a role of supporting the flexible display screen 400, and a user can conveniently use the flexible display screen 400. In this scheme, when the user does not use flexible display screen 400, flexible display screen 400 shrink is within the casing, and it is great because of flexible display screen 400 size to avoid electronic equipment's size to make electronic equipment's size less, thereby make electronic equipment's weight lighter, the user is comparatively convenient at the in-process that uses, thereby promote electronic equipment's operating comfort, and the less electronic equipment convenience of customers one-hand operation of size, and then improve user's use and experience. Meanwhile, the electronic equipment with the small size does not need a large storage space when being stored, and is convenient for a user to carry, so that the problems that a mobile phone with a large display screen is inconvenient for the user to operate and the portability is poor are solved.
As mentioned above, the driving mechanism 300 can be of various types, in an alternative embodiment, the electronic device can further include a power source, the driving mechanism 300 can include the piezoelectric material portion 310, the piezoelectric material portion 310 is electrically connected to the power source, the piezoelectric material portion 310 is in driving connection with the spool 200, and the piezoelectric material portion 310 can drive the spool 200 to rotate when the piezoelectric material portion 310 is energized. The piezoelectric material portion 310 is deformable when energized, and the deformation of the piezoelectric material portion 310 generates rotational displacement, thereby driving the spool 200 to rotate. The driving mechanism 300 in the form is simple in structure, reliable in driving process, fast in response and high in precision, and meanwhile, noise is difficult to generate in the running process of the driving mechanism 300 in the form, so that a user feels comfortable in the using process. It should be noted that the power source of the electronic device may be a battery carried by the electronic device itself, or a battery separately disposed in the casing 100 and supplying power to the driving mechanism 300, which is not limited in the embodiment of the present invention.
When the piezoelectric material portion 310 is energized, the piezoelectric material portion 310 alternately expands and contracts, and the piezoelectric material portion 310 forms a traveling wave rotating in the circumferential direction of the circular ring under the action of a certain frequency and voltage, and the traveling wave propagates in the circumferential direction of the spool 200, thereby driving the spool 200 to rotate. The principle of the piezoelectric material portion 310 generating the rotational displacement is known in the art, and is not described herein for brevity.
Specifically, the material of the piezoelectric material portion 310 may be classified into three main groups in terms of crystallization, the first group being a single crystal structure such as quartz; the second type is polycrystalline structures, for example ceramics such as the piezoelectric ceramics BaTiO3, PZT; the third type is a polymeric piezoelectric material, such as PVDF. Since the piezoelectric ceramic has advantages of acid and alkali resistance, high energy conversion efficiency, no electromagnetic interference, and simple structure, the piezoelectric material portion 310 may be preferably made of the piezoelectric ceramic in the present invention.
In order to increase the amount of deformation of the piezoelectric material portion 310, in addition to increasing the current or voltage provided on the piezoelectric material portion 310, the driving mechanism 300 may optionally further include an elastic body 320, the elastic body 320 being provided on the piezoelectric material portion 310, the piezoelectric material portion 310 being connected to the spool 200 through the elastic body 320. The elastic body 320 is in contact with the piezoelectric material portion 310, and deformation occurring when the piezoelectric material portion 310 operates can be amplified by the elastic body 320, so that the amount of deformation of the piezoelectric material portion 310 can be increased. Specifically, the elastic body 320 may be an elastic sheet attached to the surface of the piezoelectric material portion 310.
In the specific driving process of the driving mechanism 300, the piezoelectric material portion 310 rotates, the elastic body 320 on the surface of the piezoelectric material portion 310 contacts with the scroll 200, and the elastic body 320 drives the scroll 200 to rotate through friction, in this process, if the friction force between the elastic body 320 and the scroll 200 is small, a slip situation occurs between the elastic body 320 and the scroll 200, and then the piezoelectric material portion 310 is difficult to output power to the scroll 200. Based on this, in an alternative embodiment, the driving mechanism 300 may further include a wear-resistant portion 330, the wear-resistant portion 330 is connected to the spool 200, the elastic body 320 contacts the wear-resistant portion 330 when the piezoelectric material portion 310 is energized, and the piezoelectric material portion 310 drives the spool 200 to rotate through the elastic body 320 and the wear-resistant portion 330. The wear-resistant part 330 can increase the friction between the elastic body 320 and the scroll 200 and prevent the elastic body 320 and the scroll 200 from slipping, so that the elastic body 320 can effectively drive the scroll 200 to rotate, the reliability and stability of the driving mechanism 300 for driving the scroll 200 to rotate are improved, and the user experience is further improved.
Specifically, the wear-resistant portion 330 may be a carbon nanosheet, because the wear-resistant property of the carbon nanosheet is high, it is avoided that the wear-resistant portion 330 is worn in a large amount, which results in a short time for using the wear-resistant portion 330, and thus the service life of the driving mechanism 300 is prolonged.
As described above, in the case where the flexible display 400 is at least partially retracted into the housing 100, the supporting part 500 is in a flexible state; in a case where the flexible display 400 is at least partially protruded out of the housing 100, the supporting part 500 is in a rigid state. Specifically, the supporting portion 500 may be various in types, and in an alternative embodiment, the supporting portion 500 may include a first frame 510, a plurality of magnetorheological body portions 520 and a plurality of electromagnetic portions 530 may be disposed at intervals in the first frame 510, and the plurality of magnetorheological body portions 520 and the plurality of electromagnetic portions 530 are disposed in a one-to-one correspondence manner; with the electromagnet portion 530 energized, the magnetorheological body portion 520 is in a solid state and the support portion 500 is in a rigid state; with the electromagnet portion 530 not energized, the magnetorheological body portion 520 is in a liquid state and the support portion 500 is in a flexible state.
In a specific working process of the electronic device, when a user needs to use the flexible display screen 400, the driving mechanism 300 drives the reel 200 to rotate in the second rotation direction, so as to drive the flexible display screen 400 to at least partially extend out of the housing 100 through the opening 110, in a process that the flexible display screen 400 at least partially extends out of the housing 100, or after the flexible display screen 400 at least partially extends out of the housing 100, the electromagnetic portion 530 is energized, the electromagnetic portion 530 generates a magnetic field after being energized, the magnetic field can enable the magnetorheological portion 520 to be in a solid state, so that the supporting portion 500 is in a rigid state, and the supporting portion 500 further supports the flexible display screen 400 to display, thereby facilitating the user to use the flexible display screen 400. When the user does not use the flexible display 400 or the user uses the flexible display 400, the driving mechanism 300 drives the roller 200 to rotate in the first rotation direction, so as to drive the flexible display 400 to retract at least partially into the housing 100 through the opening 110, when the flexible display 400 is at least partially ready to retract into the housing 100, or when the flexible display 400 retracts at least partially into the housing 100, the electromagnetic portion 530 is powered off, the magnetic field generated by the electromagnetic portion 530 disappears, and the magnetorheological body portion 520 is converted from the solid state to the liquid state, so that the support portion 500 is in the flexible state, thereby facilitating the flexible display 400 to be at least partially wound on the roller 200.
Further, the plurality of electromagnetic portions 530 are electrically connected to a power source, respectively, and each of the electromagnetic portions 530 is provided with an independent line control device, so that the plurality of electromagnetic portions 530 can be individually controlled. In the specific extending process of the flexible display screen 400, the electronic device may detect the extending condition of the flexible display screen 400, and then control the electromagnetic portion 530 corresponding to the extending portion of the flexible display screen 400 to be powered on; in a specific retraction process of the flexible display screen 400, the electronic device may detect a retraction condition of the flexible display screen 400, and then control the electromagnetic portion 530 corresponding to the retraction portion of the flexible display screen 400 to be powered off. In this way, the supporting portion 500 corresponding to the portion of the flexible display 400 located outside the housing 100 is in a rigid state, and the supporting portion 500 corresponding to the portion of the flexible display 400 located inside the housing 100 is in a flexible state, so as to facilitate the flexible display 400 to extend or retract.
In another alternative embodiment, the supporting portion 500 may include a second frame 540, a plurality of current transformer portions 550 may be disposed at intervals in the second frame 540, and when the current transformer portions 550 are powered on, the current transformer portions 550 are in a solid state, and the supporting portion 500 is in a rigid state; in a case where the current transformer 550 is not energized, the current transformer 550 is in a liquid state, and the support part 500 is in a flexible state.
In the specific working process of the electronic device, in the process that the flexible display screen 400 at least partially extends out of the casing 100, or after the flexible display screen 400 at least partially extends out of the casing 100, the current transformer 550 is powered on, and the current transformer 550 is converted from the liquid state to the solid state, so that the support part 500 is in the rigid state, and the support part 500 supports the flexible display screen 400 to display, thereby facilitating the use of the flexible display screen 400 by a user. During the process that the flexible display 400 is at least partially ready to be retracted into the casing 100, or during the process that the flexible display 400 is at least partially retracted into the casing 100, the current transformer 550 is powered off, and the current transformer 550 is transformed from the solid state to the liquid state, so that the support 500 is in the flexible state, thereby facilitating the flexible display 400 to be at least partially wound around the reel 200.
Similarly, the plurality of current bodies 550 are electrically connected to a power source, respectively, and each current body 550 is provided with an independent line control device, so that the plurality of current bodies 550 can be individually controlled. In the specific extending process of the flexible display screen 400, the electronic device may detect the extending condition of the flexible display screen 400, and then control the current transformer 550 corresponding to the extending portion of the flexible display screen 400 to be powered on; in a specific retraction process of the flexible display screen 400, the electronic device may detect a retraction condition of the flexible display screen 400, and then control the current transformer 550 corresponding to the retracted portion of the flexible display screen 400 to be powered off. In this way, the supporting portion 500 corresponding to the portion of the flexible display 400 located outside the housing 100 is in a rigid state, and the supporting portion 500 corresponding to the portion of the flexible display 400 located inside the housing 100 is in a flexible state, so as to facilitate the flexible display 400 to extend or retract.
In order to further improve the supporting effect of the supporting portion 500 on the flexible display screen 400, in an alternative embodiment, the number of the supporting portions 500 may be multiple, the two opposite side edges of the flexible display screen 400 may be connected with the supporting portions 500, and the supporting portions 500 extend towards the stretching direction of the flexible display screen 400. That is to say, the flexible display screen 400 all is connected with the supporting part 500 at the border that extends in flexible direction, and a plurality of supporting parts 500 support flexible display screen 400 simultaneously, can further improve the supporting effect of supporting part 500 to flexible display screen 400 undoubtedly to can be more convenient for the user to operate flexible display screen 400, and then improve electronic equipment's maneuverability.
In the specific retraction process of the flexible display 400, there may be a case that the flexible display 400 is fully retracted into the housing 100, and in the case that the flexible display 400 is fully retracted into the housing 100, when the flexible display 400 needs to be extended, the flexible display 400 is difficult to be extended in alignment with the opening 110, so that the electronic device cannot be used. Based on this, in an alternative embodiment, a first end of the flexible display 400 may be connected to the scroll 200, a second end of the flexible display 400 is located outside the housing 100, a winding portion of the flexible display 400 between the first end and the second end may be extended out of the housing 100 or retracted into the housing 100 through the opening 110, and in a case where the winding portion is retracted into the housing 100, the winding portion is wound around the scroll 200; the second end is provided with a limit stop 600, and the limit stop 600 is in limit fit with the opening 110 when the flexible display screen 400 is at least partially retracted into the casing 100. Spacing baffle 600 can be in flexible display screen 400 when retracting with the spacing cooperation of opening 110 to make the second end of flexible display screen 400 be located outside casing 100, prevent that flexible display screen 400 is whole to retract within casing 100, make things convenient for flexible display screen 400 to stretch out once more, avoid flexible display screen 400 because of difficult stretching out and lead to the unable condition of using of electronic equipment to take place, and then improve electronic equipment's reliability.
In order to enable the flexible display 400 to extend or retract quickly, in an alternative embodiment, a side of the position limiting baffle 600 facing the casing 100 may be provided with a first magnetic part 710, the opening 110 may be provided with a second magnetic part 720, and at least one of the first magnetic part 710 and the second magnetic part 720 is an electromagnet; when the flexible display screen 400 is at least partially retracted into the housing 100 and the electromagnet is powered on, the first magnetic part 710 and the second magnetic part 720 are magnetically attracted; when the flexible display 400 at least partially protrudes out of the housing 100 and the electromagnet is energized, the first magnetic portion 710 and the second magnetic portion 720 magnetically repel each other.
When the flexible display screen 400 is ready to be extended, the electromagnet is energized to make the first magnetic part 710 and the second magnetic part 720 magnetically repel each other, so that the flexible display screen 400 is extended faster; during the retraction of the flexible display 400, the electromagnet is energized to magnetically attract the first magnetic part 710 and the second magnetic part 720, so that the flexible display 400 is retracted faster.
