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, when the flexible display screen 200 is in the first state, that is, when the flexible display screen 200 is in the contracted state, the first portion is located on one side where the first surface 110 is located, and the second portion is located on one side where the second surface 120 is located, at this time, the effective display area of the flexible display screen 200 of the electronic device is small, so that the requirements of a user on communication, information viewing and the like can be met, and the electronic device is small in overall size and convenient to carry; under the condition that flexible display screen 200 is in the second state, namely under the condition that electronic equipment is in the state of stretching, first portion 250 and second portion 260 all are located first face 110 place side, and first portion 250 and second portion 260 form bigger display area jointly this moment to make the effective display area of flexible display screen 200 of electronic equipment great, in order to satisfy user's large-screen demand such as watching the movie, playing games, thereby provide better use experience for the user.

Therefore, the problem that the thickness of the existing electronic equipment is large can be solved. In addition, the embodiment of the present application uses the transmission hole 240 to realize transmission, and the transmission hole 240 does not occupy additional space, so that the whole driving mechanism 300 occupies less space.

In an alternative embodiment, the flexible display panel 200 includes a display panel main body 210 and a first supporting member 220, and the first supporting member 220 and the display panel main body 210 can be configured as an integral structure or a split structure, and if the integral structure is configured, when the display panel main body 210 or the first supporting member 220 is damaged, the flexible display panel is inconvenient to maintain. Therefore, optionally, the first supporting member 220 and the display screen main body 210 are separately arranged and connected, and further optionally, the first supporting member 220 and the display screen main body 210 may be connected by bonding or the like, which is not specifically limited in this embodiment of the application. The casing 100 is provided with the sliding groove 130, the first supporting member 220 is in sliding fit with the sliding groove 130, that is, the setting 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 portion 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, with the flexible display screen 200 in the first state, the first support member 220 may be entirely located within the chute 130; 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 a 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 a 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 in sliding fit with the sliding groove 130 of the housing 100 to provide a guide for the sliding of 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 in sliding fit with the sliding groove 130, so as to drive the flexible display screen 200 to slide, but the flat plate structure has a smaller contact area with the housing 100, and has a poorer stability in the sliding process, and when the flexible display screen 200 is in the second state, the flat plate structure has a smaller contact area with the housing 100, and has a poorer supporting property for the display screen main body 210. Therefore, optionally, the first supporting member 220 includes a first plate section 221, a second plate section 222, and a third plate section 223 connected in sequence, the first plate section 221 is opposite to the third plate section 223 in the first direction, the sliding slot 130 includes a first sliding slot 131 and a second sliding slot 132, the first sliding slot 131 and the second sliding slot 132 are arranged in parallel, the first sliding slot 131 and the second sliding slot 132 are arranged at intervals in the first direction, the first plate section 221 is in sliding fit with the first sliding slot 131, and the third plate section 223 is in sliding fit with the second sliding slot 132, wherein the first direction is perpendicular to the sliding direction of the flexible display screen 200, that is, the arrangement direction of the first sliding slot 131 and the second sliding slot 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 section 221 slides along the first sliding groove 131, the third plate section 223 slides along the second sliding groove 132, at this time, the first sliding groove 131 provides a guiding function for the first plate section 221, a larger contact area can be formed between the first plate section and the third plate section, the second sliding groove 132 provides a guiding function for the third plate section 223, and a larger contact area can be formed between the second plate section and the third plate section, so that the stability of the flexible display screen 200 in the sliding process is improved, and meanwhile, the supporting effect on the display screen main body 210 is improved.

Further optionally, the open side of the first sliding chute 131 faces the open side of the second sliding chute 132, that is, the open side of the first sliding chute 131 is disposed opposite to the open side of the second sliding chute 132, and the first supporting element 220 is located between the first sliding chute 131 and the second sliding chute 132. The first support 220 further includes a first sliding portion 224 and a second sliding portion 225, the first sliding portion 224 is disposed on the first plate section 221, the first sliding portion 224 is engaged with the first sliding groove 131, an opening side of the first sliding portion 224 faces a bottom surface of the first sliding groove 131, that is, the first sliding portion 224 is a groove-shaped structure, and an opening side of the first sliding portion 224 faces an opposite direction to the opening side of the first sliding groove 131; the second sliding portion 225 is disposed on the third plate segment 223, the second sliding portion 225 is matched with the second sliding slot 132, an opening side of the second sliding portion 225 faces a bottom surface of the second sliding slot 132, that is, the second sliding portion 225 is a groove-shaped structure, and an opening side of the second sliding portion 225 faces opposite to an opening side of the second sliding slot 132, when the flexible display panel 200 is switched between the first state and the second state, the first sliding portion 224 is matched with the first sliding slot 131 to slide, the second sliding portion 225 is matched with the second sliding slot 132 to slide, because the first sliding portion 224 and the second sliding portion 225 are both groove-shaped structures, contact areas between the first sliding portion 224 and the first sliding slot 131 and between the second sliding portion 225 and the second sliding slot 132 are both 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 which are 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 which are arranged oppositely, in the process that the first supporting member 220 slides 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 that the first sliding portion 224 is prevented 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 which are 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 is provided with a third limiting groove 225a and a fourth limiting groove 225b which are arranged in a back direction, 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, the fourth limiting protrusion is in limiting fit with the fourth limiting groove 225b, and therefore the second sliding portion 225 is prevented from being separated from the second sliding groove 132. Therefore, the embodiment of the application can further ensure that the first supporting member 220 can accurately slide along the preset direction of the sliding groove 130 all the time by adopting the limiting structure, so that the flexible display screen 200 is prevented from deviating, and the limiting structure is simpler.

If the transmission hole 240 is disposed on the first plate section 221 or the third plate section 223, the force applied by the driving mechanism 300 to the first supporting member 210 may cause the flexible display 200 to tilt during the sliding process; in addition, since the areas of the first plate section 221 and the third plate section 223 are small, the design difficulty of the transmission hole 240 is increased. Therefore, in an alternative embodiment, the second plate section 222 is provided with the transmission hole 240, and the second plate section 222 is located between the first plate section 221 and the third plate section 223, so that the driving mechanism 300 can drive the flexible display screen 200 to slide more smoothly, and the second plate section 222 has a larger area, so that the transmission hole 240 can be conveniently arranged, and the design difficulty can be reduced. In addition, under this structure, the transmission hole 240 fully utilizes the space in the thickness direction of the electronic device, and the transmission hole 240 does not occupy additional space, so the thickness of the electronic device can be further reduced.

In an alternative embodiment, the flexible display screen 200 further includes a second supporting member 230, and the display screen main body 210, the first supporting member 220, and the second supporting member 230 may be disposed in an integrated structure, or at least two of them may be disposed in an integrated structure, which is not particularly limited in this embodiment. The edge of the second supporting member 230 extends to the edge of the display screen main body 210, that is, the shape of the second supporting member 230 is the same as the shape of the display screen main body 210, the area of the second supporting member 230 is the same as the area of the display screen main body 210, and the first supporting member 220 is connected to the display screen main body 210 through the second supporting member 230, that is, the display screen main body 210, the second supporting member 230 and the first supporting member 220 are sequentially stacked, and in a direction perpendicular to the second portion 260, the orthographic projection of the first supporting member 220 is located within the orthographic projection of the second supporting member 230, that is, the area of the first supporting member 220 is smaller than the area of the second supporting member 230. Specifically, when the flexible display panel 200 is switched between the first state and the second state, the driving source 310 drives the first supporting member 220 to slide through the rotating member 320, and the first supporting member 220 is connected to the display panel main body 210 through the second supporting member 230, so that the first supporting member 220 drives the second supporting member 230 and the display panel main body 210 to slide together. At this time, the area of the second supporting member 230 is larger than that of the first supporting member 220, so that the second supporting member 230 provides a 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 a user to perform 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 left on two sides of the first supporting member 220, and the space can be used for arranging structures (such as the first sliding portion 224 and the second sliding portion 225) matched with the sliding chute 130, and therefore, the structure can reduce the difficulty of structural design of the electronic device.

In a further alternative embodiment, at least one of the first support member 220 and the second support member 230 includes a rigid portion, and the rigid portion protrudes relative to the housing 100 when the flexible display screen 200 is in the second state, that is, when the flexible display screen 200 is in the extended state, a portion of the first support member 220 corresponding to the protruding portion of the flexible display screen 200 may be set as the rigid portion, a portion of the second support member 230 corresponding to the protruding portion of the flexible display screen 200 may be set as the rigid portion, both portions may be set as the rigid portions, and the other portions of the flexible display screen 200 may be set as the flexible portions, so as to meet the requirement that the flexible display screen 200 is bendable during sliding. Specifically, under the condition that the flexible display screen 200 is in the second state, since the rigid portion has a stronger supporting function, the rigid portion extends out of the housing 100 at this time, and can provide a stronger supporting force for the display screen main body 210, so that the portion is not easily broken; secondly, the rigid part enables the user to perform touch operation more powerfully in scenes such as entertainment, video watching or games, and meanwhile, the flatness of the display screen body 210 is kept, so that 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 disposed on the flexible display 200 may be biased toward the first side or the second side, which means that the driving force distributed on the flexible display 200 and output by the driving source 310 is biased toward the first side or the second side, and the flexible display 200 may be tilted due to unbalanced stress during the sliding process of the flexible display 200. Therefore, optionally, the distance between the transmission hole 240 and the first side surface is equal to the distance between the transmission hole 240 and the second side surface, wherein the first direction is perpendicular to the sliding direction of the flexible display screen 200, that is, the transmission 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 applied to the flexible display screen 200 during the sliding process is relatively balanced, thereby preventing the flexible display screen 200 from tilting.

As mentioned above, the transmission part 323 of the rotating member 320 may be a cylindrical structure, but the root of the cylindrical structure is easily broken, resulting in poor reliability of the rotating member 320. Therefore, alternatively, the driving source 310 is provided with an output shaft, the rotating member 320 includes the gear 321, and the transmission part 323 is a transmission tooth whose root is not easily broken, so that the reliability of such a rotating member 320 is high. The gear 321 and the output shaft are coaxially arranged, the transmission teeth are meshed with the transmission hole 240, and the gear 321 has the characteristics of compact structure, high efficiency and long service life, so that other structural layouts in the shell 100 can be conveniently arranged by adopting the gear 321 for transmission, and the structure in the shell 100 is more compact.

Further alternatively, the driving mechanism 300 further comprises a speed reducer, wherein the speed reducer 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 to adapt to the condition required by the flexible display 200 to switch between the first state and the second state, so that the driving source 310 can work under a better working condition.

Still further optionally, the rotating component 320 further includes a bearing 322, and optionally, the bearing 322 may be a ball bearing to support a large load, and of course, other types of bearings 322 may be also used, which is not particularly limited in the embodiments of the present application. The number of the bearings 322 may be at least two, each bearing 322 may be disposed on both sides of the gear 321, and the bearings 322 may ensure that both sides of the gear 321 are balanced during the driving source 310 drives the gear 321 to rotate, so that the entire driving mechanism 300 operates more stably.

In an alternative embodiment, the arrangement direction of the transmission holes 240 is parallel to the sliding direction of the flexible display screen 200, when the driving source 310 drives the flexible display screen 200 to switch between the first state and the second state, the transmission portion 323 cooperates with the transmission holes 240, the driving force output by the driving source 310 is in the arrangement direction of the transmission holes 240, so as to drive the flexible display screen 200 to slide, and at this time, the driving mechanism 300 uses a smaller driving force to change the effective display area of the flexible display screen 200. Therefore, the arrangement of the transmission holes 240 can improve the working efficiency of the driving source 310, and the arrangement is simple, which is beneficial to the structural design of the rotating member 320.

The electronic device disclosed in the embodiment of the present application may be an electronic device such as a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), and an electronic game machine, and the kind of the electronic device is not particularly limited in the embodiment of the present application.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
