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.
Referring to fig. 1 to 5, an embodiment of the present application discloses an electronic apparatus including a housing 100, a flexible display screen 200, and a driving mechanism 300.
The housing 100 is a base member of an electronic device, and can provide a mounting base for other structures of the electronic device, and the housing 100 has a first face 110 and a second face 120 disposed opposite to each other. The first surface 110 may be a front surface of the electronic device, and the second surface 120 may be a back surface of the electronic device.
The flexible display screen 200 is disposed on the housing 100, and the flexible display screen 200 is slidably engaged with the housing 100, that is, the flexible display screen 200 can slide relative to the housing 100. The inner surface of the flexible display screen 200 is provided with a plurality of transmission holes 240 arranged at intervals, alternatively, the transmission holes 240 may be square transmission holes, circular transmission holes, or the like, which is not particularly limited in the embodiment of the present application. The flexible display screen 200 includes a first portion 250 and a second portion 260 connected, where the first portion 250 and the second portion 260 are arranged along a sliding direction of the flexible display screen 200.
The driving mechanism 300 is disposed in the housing 100, and the driving mechanism 300 includes a driving source 310 and a rotating member 320, alternatively, the driving source 310 may be a motor, a cylinder, a hydraulic cylinder, a piezoelectric ceramic, a shape memory alloy, a coil spring, or the like, wherein: the motor has the characteristics of small volume, high efficiency and convenient control; the cylinder and the hydraulic cylinder have the characteristics of large output force and stable and reliable performance; the piezoelectric ceramic, the shape memory alloy and the coil spring have the characteristics of green and environment protection, and the embodiment of the application does not limit the specific form of the driving source 310. The rotating member 320 is rotatable under the driving action of the driving source 310, and is provided with a plurality of transmission parts 323, wherein the plurality of transmission parts 323 are disposed around the rotation axis of the rotating member 320, and the transmission parts 323 are engaged with the transmission holes 240, in other words, during the rotation of the rotating member 320, different transmission parts 323 are engaged with different transmission holes 240, thereby driving the flexible display screen 200 to slide. Alternatively, the driving part 323 may have a cylindrical structure, and accordingly the driving hole 240 is a circular driving hole, and the driving part 323 may be inserted into the driving hole 240 to be engaged with the driving hole 240. The driving source 310 drives the flexible display screen 200 to switch between the first state and the second state through the transmission part 323, specifically, in the case that the flexible display screen 200 is in the first state, namely, in the case that the flexible display screen 200 is in the contracted state, the first part is positioned on the side where the first surface 110 is positioned, and the second part is positioned on the side where the second surface 120 is positioned, at this time, the effective display area of the flexible display screen 200 of the electronic device is smaller, the requirements of users on conversation, information viewing and the like can be met, and the whole size of the electronic device is smaller, so that the electronic device is convenient to carry; in the case that the flexible display screen 200 is in the second state, that is, in the case that the electronic device is in the extended state, the first portion 250 and the second portion 260 are both located on the side where the first face 110 is located, at this time, the first portion 250 and the second portion 260 together form a larger display area, so that the effective display area of the flexible display screen 200 of the electronic device is larger, so as to meet the requirements of watching movies, playing games and the like on a large screen of a user, and provide a better use experience for the user.
In the embodiment of the application, the flexible display screen 200 is in sliding fit with the housing 100, the inner surface of the flexible display screen 200 is provided with a plurality of transmission holes 240 which are arranged at intervals, and the transmission part 323 arranged on the rotating member 320 is matched with the transmission holes 240, so that the driving source 310 drives the flexible display screen 200 to switch between the first state and the second state through the transmission part 323. Therefore, the embodiment of the application can solve the problem of larger thickness of the current electronic equipment. In addition, the embodiment of the present application uses the transmission hole 240 to realize transmission, and the transmission hole 240 occupies no extra space, so that the space occupied by the whole driving mechanism 300 is smaller.
In an alternative embodiment, the flexible display screen 200 includes a display screen main body 210 and a first support member 220, and the first support member 220 and the display screen main body 210 may be provided as a single structure or as a separate structure, if provided as a single structure, and maintenance is inconvenient when the display screen main body 210 or the first support member 220 is damaged. Therefore, alternatively, the first supporting member 220 and the display main body 210 are separately disposed and connected, and further alternatively, the first supporting member 220 and the display main body 210 may be connected by bonding, etc., which is not particularly limited in the embodiment of the present application. The housing 100 is provided with a sliding groove 130, the first supporting member 220 is slidably matched with the sliding groove 130, that is, the arrangement direction of the sliding groove 130 is matched with the sliding direction of the first supporting member 220, the first supporting member 220 is provided with a transmission hole 240, that is, the transmission part 323 is matched with the transmission hole 240 arranged on the first supporting member 220, so that the first supporting member 220 drives the display screen main body 210 to switch between the first state and the second state. Alternatively, the first support 220 may be entirely located within the chute 130 with the flexible display screen 200 in the first state; under the condition that the flexible display screen 200 is in the second state, the first supporting member 220 at least partially extends out of the sliding groove 130, and at this time, the first supporting member 220 can support the display screen main body 210 to provide supporting force for the display screen main body 210, so that the surface of the flexible display screen 200 is still flat under the condition that the effective display area is increased, and better use experience is provided for a user. Therefore, in the embodiment of the present application, the first supporting member 220 not only can provide a supporting force for the display main body 210 to enhance the rigidity of the flexible display 200, but also can be slidably matched with the sliding groove 130 of the housing 100, thereby providing a guide for sliding the flexible display 200.
The first supporting member 220 may be a flat plate structure, and two sides of the flat plate structure may be directly slidably matched with the sliding groove 130, so as to drive the flexible display screen 200 to slide, but the contact area between the flat plate structure and the housing 100 is smaller, stability is worse in the sliding process, and in the case that the flexible display screen 200 is in the second state, the support to the display screen main body 210 is worse due to the smaller contact area between the flat plate structure and the housing 100. Therefore, optionally, the first supporting member 220 includes a first plate segment 221, a second plate segment 222 and a third plate segment 223 sequentially connected, the first plate segment 221 and the third plate segment 223 are opposite in a first direction, the sliding chute 130 includes a first sliding chute 131 and a second sliding chute 132, the first sliding chute 131 and the second sliding chute 132 are disposed in parallel, the first sliding chute 131 and the second sliding chute 132 are arranged at intervals in the first direction, the first plate segment 221 is in sliding fit with the first sliding chute 131, the third plate segment 223 is in sliding fit with the second sliding chute 132, and the first direction is perpendicular to the sliding direction of the flexible display screen 200, that is, the setting direction of the first sliding chute 131 and the second sliding chute 132 is parallel to the sliding direction of the flexible display screen 200. Specifically, when the flexible display screen 200 is switched between the first state and the second state, the first plate segment 221 slides along the first chute 131, the third plate segment 223 slides along the second chute 132, at this time, the first chute 131 provides a guiding function for the first plate segment 221, a larger contact area can be formed between the first and the third plate segments, and the second chute 132 provides a guiding function for the third plate segment 223, a larger contact area can be formed between the third and the third plate segments, so that the stability of the flexible display screen 200 in the sliding process is improved, and the supporting effect on the display screen main body 210 is improved.
Further alternatively, the opening side of the first chute 131 is directed toward the opening side of the second chute 132, i.e., the opening side of the first chute 131 is disposed opposite to the opening side of the second chute 132, with the first support 220 being located between the first chute 131 and the second chute 132. The first support 220 further includes a first sliding portion 224 and a second sliding portion 225, where the first sliding portion 224 is disposed on the first plate segment 221, the first sliding portion 224 is matched with the first sliding chute 131, and an opening side of the first sliding portion 224 faces to a bottom surface of the first sliding chute 131, that is, the first sliding portion 224 is in a groove-shaped structure, and the opening side of the first sliding portion 224 faces to an opposite direction to the opening side of the first sliding chute 131; the second sliding portion 225 is disposed on the third plate section 223, the second sliding portion 225 is matched with the second sliding groove 132, the opening side of the second sliding portion 225 faces the bottom surface of the second sliding groove 132, that is, the second sliding portion 225 is in a groove-shaped structure, and the opening side of the second sliding portion 225 faces the opening side of the second sliding groove 132 in the opposite direction, when the flexible display screen 200 is switched between the first state and the second state, the first sliding portion 224 is matched with the first sliding groove 131 to slide, the second sliding portion 225 is matched with the second sliding groove 132 to slide, and since the first sliding portion 224 and the second sliding portion 225 are in the groove-shaped structure, the contact areas of the first sliding portion 224 and the first sliding groove 131 and the contact areas of the second sliding portion 225 and the second sliding groove 132 are larger, so that the first supporting member 220 is more stable in the sliding process.
In a further alternative embodiment, the first sliding groove 131 has a first inner wall surface 131a and a second inner wall surface 131b opposite to each other, the first inner wall surface 131a is provided with a first limiting protrusion, the second inner wall surface 131b is provided with a second limiting protrusion, the first sliding portion 224 has a first limiting groove 224a and a second limiting groove 224b opposite to each other, and during the sliding process of the first supporting member 220 along the sliding groove 130, the first limiting protrusion is in limiting fit with the first limiting groove 224a, and the second limiting protrusion is in limiting fit with the second limiting groove 224b, so as to prevent the first sliding portion 224 from being separated from the first sliding groove 131. Similarly, the second sliding groove 132 has a third inner wall surface 132a and a fourth inner wall surface 132b opposite to each other, the third inner wall surface 132a is provided with a third limiting protrusion, the fourth inner wall surface 132b is provided with a fourth limiting protrusion, the second sliding portion 225 has a third limiting groove 225a and a fourth limiting groove 225b disposed opposite to each other, and in the sliding process of the first supporting member 220 along the sliding groove 130, the third limiting protrusion is in limiting fit with the third limiting groove 225a, and the fourth limiting protrusion is in limiting fit with the fourth limiting groove 225b, so as to prevent the second sliding portion 225 from being separated from the second sliding groove 132. Therefore, the adoption of the limiting structure in the embodiment of the application can further ensure that the first supporting member 220 always slides precisely along the preset direction of the chute 130, so as to avoid the deflection of the flexible display screen 200, and the limiting structure is simpler.
If the transmission hole 240 is provided in the first plate segment 221 or the third plate segment 223, the force of the driving mechanism 300 acting on the first support 210 may tilt the flexible display screen 200 during sliding; in addition, the smaller areas of the first plate segment 221 and the third plate segment 223 will increase the difficulty in designing the driving hole 240. Therefore, in an alternative embodiment, the second plate segment 222 is provided with the transmission hole 240, and the second plate segment 222 is located between the first plate segment 221 and the third plate segment 223, so that the driving mechanism 300 can drive the flexible display screen 200 to slide more smoothly, and the arrangement of the transmission hole 240 is facilitated due to the larger area of the second plate segment 222, so that the design difficulty is reduced. In addition, with this structure, the transmission hole 240 fully utilizes the space in the thickness direction of the electronic device, and the thickness of the electronic device can be further reduced because the transmission hole 240 does not occupy additional space.
In an alternative embodiment, the flexible display screen 200 further includes a second support member 230, where the display screen main body 210, the first support member 220, and the second support member 230 may be configured as a single structure, or at least two of them may be configured as a split structure, which is not particularly limited in this embodiment of the present application. The edge of the second support 230 extends to the edge of the display main body 210, i.e., the shape of the second support 230 is the same as the shape of the display main body 210, and the area of the second support 230 is equal to the area of the display main body 210, the first support 220 is connected to the display main body 210 through the second support 230, i.e., the display main body 210, the second support 230, and the first support 220 are sequentially stacked, and in a direction perpendicular to the second portion 260, the orthographic projection of the first support 220 is located within the orthographic projection of the second support 230, i.e., the area of the first support 220 is smaller than the area of the second support 230. Specifically, when the flexible display screen 200 is switched between the first state and the second state, the driving source 310 drives the first support 220 to slide through the rotation member 320, and the first support 220 is connected to the display screen main body 210 through the second support 230, so that the first support 220 drives the second support 230 to slide together with the display screen main body 210. At this time, the area of the second supporting member 230 is larger than that of the first supporting member 220, so the second supporting member 230 provides supporting force for the whole display area of the display screen main body 210, so that the display screen main body 210 presents a better display effect, and is beneficial for the user to implement touch operation; in addition, the area of the first supporting member 220 is smaller than that of the second supporting member 230, so that a certain space can be reserved on both sides of the first supporting member 220, and the space can be used for providing structures (such as the first sliding portion 224 and the second sliding portion 225) matched with the sliding slot 130, so that the difficulty in structural design of the electronic device can be reduced.
In a further alternative embodiment, at least one of the first support 220 and the second support 230 includes a rigid portion that protrudes with respect to the housing 100 when the flexible display 200 is in the second state, that is, when the flexible display 200 is in the extended state, a portion of the first support 220 corresponding to the protruding portion of the flexible display 200 may be provided as a rigid portion, a portion of the second support 230 corresponding to the protruding portion of the flexible display 200 may be provided as a rigid portion, both portions may be provided as a rigid portion, and other portions of the flexible display 200 may be provided as flexible portions to meet the requirement that the flexible display 200 is bendable during sliding. Specifically, in the case where the flexible display screen 200 is in the second state, since the rigid portion has a stronger supporting effect, the rigid portion extends out of the housing 100 at this time, a stronger supporting force can be provided for the display screen main body 210, so that the portion is not easily broken; secondly, the rigid portion can enable the user to perform touch operation more forcefully in the scenes such as entertainment, movie watching or game, and meanwhile, the flatness of the display screen body 210 is maintained, and further better use experience is obtained.
In an alternative embodiment, the housing 100 has a first side and a second side opposite to each other in the first direction, and the transmission hole 240 provided on the flexible display screen 200 may be biased to the first side or the second side, which means that the driving force output by the driving source 310 and distributed on the flexible display screen 200 is biased to the first side or the second side, and may cause the flexible display screen 200 to tilt due to unbalanced stress during the sliding of the flexible display screen 200. Therefore, optionally, the distance between the driving hole 240 and the first side is equal to the distance between the driving hole 240 and the second side, wherein the first direction is perpendicular to the sliding direction of the flexible display screen 200, that is, the driving hole 240 is located at the middle position of the flexible display screen 200, and the driving force output by the driving source 310 acts on the middle portion of the flexible display screen 200, so that the driving force received by the flexible display screen 200 during the sliding process is balanced, and tilting of the flexible display screen 200 is avoided.
As mentioned above, the transmission part 323 of the rotation member 320 may have a cylindrical structure, but the root of the cylindrical structure is easily broken, resulting in poor reliability of the rotation member 320. Therefore, alternatively, the driving source 310 is provided with an output shaft, the rotating member 320 includes a gear 321, and the transmission portion 323 is a transmission tooth, and the root portion of the transmission tooth is not easily broken, so that the reliability of such a rotating member 320 is high. The gear 321 is coaxially arranged with the output shaft, and the transmission teeth are meshed with the transmission hole 240, so that the gear 321 is adopted for transmission, thereby being convenient for other structural layout in the shell 100 and enabling the structure in the shell 100 to be more compact due to the characteristics of compact structure, high efficiency and long service life of the gear 321.
Further optionally, the driving mechanism 300 further includes a reducer, which can change the transmission ratio of the output shaft, and expand the variation range of the torque and the rotation speed of the output shaft, so as to adapt to the condition required by the flexible display screen 200 to switch between the first state and the second state, so that the driving source 310 works under a preferred working condition.
Still further alternatively, the rotating member 320 may further include a bearing 322, alternatively, the bearing 322 may be a ball bearing so as to withstand a relatively large load, and of course, other types of bearings 322 are also possible, which is not particularly limited in this embodiment of the present application.
