Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a retractable screen assembly and electronic equipment. Background Art

[0002] With the development of science and technology and the improvement of living standards, more and more electronic devices are being used in people's daily lives and work. Electronic devices have brought great convenience to people's daily lives and work, and have become an indispensable and important tool in today's society.

[0003] Among them, the display screen is a component on an electronic device used to display images, text and other information. In order to make the display area size of the display screen meet different usage requirements, the display screens in related technologies mostly use retractable screens. However, due to the immature development of technology, the assembly of electronic devices with retractable screens in related technologies is relatively inconvenient. Summary of the Invention

[0004] The present application provides a retractable screen assembly and an electronic device, which are used to solve the problem of inconvenient assembly of electronic devices with retractable screens in the related art.

[0005] In a first aspect, the present application provides a retractable screen assembly, comprising:

[0006] frame;

[0007] A display screen, comprising a first display portion and a second display portion, wherein the first display portion is connected to the second display portion;

[0008] A driving structure is provided in the frame, and the driving structure includes a driving unit, a first movable part and a second movable part, the first movable part is connected to the first display part, and the second movable part is connected to the second display part. The driving unit is used to drive the first movable part and the second movable part to move in opposite directions, thereby driving the display screen to expand or retract.

[0009] In a second aspect, the present application provides an electronic device comprising the above-mentioned retractable screen assembly.

[0010] The retractable screen assembly and electronic device of the present application can drive the first movable part and the second movable part to move in opposite directions through a driving unit, and the first display part of the display screen is connected to the first movable part, and the second display part of the display screen is connected to the second movable part. In this way, when the driving unit drives the first movable part and the second movable part to move in opposite directions, the display screen can be expanded or retracted. Since the retractable screen assembly can achieve the expansion or retraction of the display screen through only one driving unit, the structure of the retractable screen assembly can be simplified, the size of the retractable screen assembly can be reduced, and the electronic device can be made thinner and smaller. Compared with the related art of driving the display screen to expand or retract by a rope, because the rope has a certain elasticity and requires a large force to be tightened during assembly, the connection method of the first display part of the display screen and the first movable part, and the connection method of the second display part and the second movable part in the present application is simpler, which is conducive to improving the assembly efficiency of the retractable screen assembly and saving time and effort.

[0021] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0022] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0023] The embodiment of the present application provides a retractable screen assembly 100 of an electronic device 10, see Figure 1 and Figure 3 The retractable screen assembly 100 includes a display screen 110 for displaying images, text, and other information, and a drive structure 120 for driving the display area of ​​the display screen 110 to change size. Because the display area of ​​the display screen 110 can be resized, it can meet the needs of different users or be suitable for different usage scenarios. For example, if a user needs to watch TV programs on a large screen and has ample space, the display area of ​​the display screen 110 can be increased; while when the user is carrying the device or in a limited space, the display area of ​​the display screen 110 can be reduced.

[0024] The display screen 110 can be switched between the folded state and the unfolded state under the drive of the driving structure 120. Figure 1 and Figure 2The display screen 110 may include a first display portion 111 and a second display portion 112 connected to the first display portion 111. When the display screen 110 is in a folded state, the display surface of the first display portion 111 may be exposed, and the display surface of the second display portion 112 may be hidden; when the display screen 110 is in an unfolded state, the display surface of the first display portion 111 and at least part of the display surface of the second display portion 112 may be exposed. If the retractable screen assembly 100 is used when the display screen 110 is in a folded state, the display surface of the first display portion 111 may display a picture independently. If the retractable screen assembly 100 is used when the display screen 110 is in an unfolded state, the display surface of the first display portion 111 may display a picture independently, the exposed display surface of the second display portion 112 may display a picture independently, or the exposed display surface of the second display portion 112 and the display surface of the first display portion 111 may display a picture together, so as to realize the diversification of the display area of ​​the display screen 110 and thereby meet more usage requirements.

[0025] To switch the display screen 110 between the retracted and extended states, a drive structure in related art typically includes a motor and a cable. The motor's output shaft can be connected to the display screen's first display portion, and the cable can be connected to the end of the display screen's second display portion, distal from the first display portion. This allows the cable to be released when the display screen switches from the retracted state to the extended state, allowing the second display portion to be extended under the pull of the motor and the first display portion. When the display screen switches from the extended state to the retracted state, the cable retracts, causing the second display portion to retract, and the first display portion to retract under the pull of the second display portion and the motor. However, due to the poor connection stability between the cable and the display screen and the cable's certain elasticity, significant force is required to tighten the cable during assembly, making assembly inconvenient and inefficient.

[0026] To resolve the above issues, please refer to Figures 3 to 5The driving structure 120 of the embodiment of the present application may include a driving unit 121, and a first movable portion 122 and a second movable portion 123 connected to the driving unit 121. The telescopic screen assembly 100 may also include a frame 130. The driving unit 121 may be provided in the frame 130 and used to drive the first movable portion 122 and the second movable portion 123 to move relative to the frame 130. Specifically, the first display portion 111 of the display screen 110 may be connected to the first movable portion 122, and the second display portion 112 of the display screen 110 may be connected to the second movable portion 123. The driving unit 121 may be used to drive the first movable portion 122 and the second movable portion 123 to move in opposite directions, thereby driving the display screen 110 to expand or retract. Since the telescopic screen assembly 100 can achieve the expansion or retraction of the display screen 110 by only using one driving unit 121, the structure of the telescopic screen assembly 100 can be simplified, the size of the telescopic screen assembly 100 can be reduced, and the electronic device 10 can be made thinner and smaller. Compared with the related art of using ropes to drive the display screen to expand or collapse, because the ropes have a certain degree of elasticity and require a lot of force to tighten during assembly, the connection between the first display part 111 and the first movable part 122, and the connection between the second display part 112 and the second movable part 123 of the display screen 110 in this application are simpler, which is conducive to improving the assembly efficiency of the retractable screen assembly 100 and saving time and effort.

[0027] Furthermore, the first display portion 111 of the display screen 110 can be connected to the first movable portion 122, with the display surface of the first display portion 111 exposed outside the frame 130. The end of the second display portion 112 of the display screen 110, which is away from the first display portion 111, can be located on the side where the back surface of the first display portion 111 is located and connected to the second movable portion 123. It should be noted that the back surface of the display portion refers to the side away from the display surface.

[0028] When a user views the display surface of the first display unit 111 exposed from the frame 130, the second display unit 112, located on the back side of the first display unit 111, is in a blind spot and difficult to view. Therefore, the drive structure 120 can drive the second display unit 112 to expand, exposing the expanded display surface of the second display unit 112 to the frame 130 to increase the display area of ​​the display screen 110, or drive the second display unit 112 to retract, positioning the retracted second display unit 112 on the back side of the first display unit 111 to reduce the display area of ​​the display screen 110. In this way, when the drive unit 121 drives the first movable portion 122 and the second movable portion 123 in opposite directions, if the second display unit 112 is expanded by the second movable portion 123, the first display unit 111, driven by the first movable portion 122, will pull the expanded second display unit 112 straighten, and the expanded display surface of the first display unit 111 will be exposed to the frame 130. If the second display portion 112 is retracted under the drive of the second movable portion 123 , the first display portion 111 will be retracted under the drive of the first movable portion 122 and the second display portion 112 to prevent the display screen 110 from being pulled and broken.

[0029] Specifically, if the end of the second display portion 112 connected to the second movable portion 123 moves relative to the frame 130 in the first direction to expand under the influence of the second movable portion 123, the first display portion 111 will move relative to the frame 130 in the opposite direction of the first direction under the influence of the first movable portion 122 to straighten the expanded second display portion 112. If the end of the second display portion 112 connected to the second movable portion 123 moves relative to the frame 130 in the opposite direction of the first direction under the influence of the second movable portion 123 to retract, the first display portion 111 will move relative to the frame 130 in the first direction under the influence of the first movable portion 122 to prevent the display screen 110 from being pulled and broken.

[0030] In one exemplary embodiment, see Figure 5 and Figure 6The driving unit 121 may include a first screw rod 1211, a second screw rod 1212, and a driving member 1213 for driving the first screw rod 1211 and the second screw rod 1212 to rotate. The first movable portion 122 may be sleeved on the first screw rod 1211 and threadedly connected to the first screw rod 1211, so that the first movable portion 122 can move on the first screw rod 1211 when the first screw rod 1211 rotates. The second movable portion 123 may be sleeved on the second screw rod 1212 and threadedly connected to the second screw rod 1212, so that the second movable portion 123 can move on the second screw rod 1212 when the second screw rod 1212 rotates, and the movement direction of the second movable portion 123 on the second screw rod 1212 is opposite to the movement direction of the first movable portion 122 on the first screw rod 1211. The reverse movement of the first movable portion 122 and the second movable portion 123 is achieved by two screw rods, so that the driving unit 121 has a simple structure and a small size, and requires less space in the electronic device 10, which is conducive to lightweighting and miniaturization of the electronic device 10.

[0031] In an exemplary embodiment, the first screw rod 1211 can be connected to the second screw rod 1212, and one of the first screw rod 1211 and the second screw rod 1212 can be connected to the driving member 1213 so that the driving member 1213 can drive the first screw rod 1211 and the second screw rod 1212 to rotate synchronously in the same direction. In order to make the movement directions of the first movable part 122 sleeved on the first screw rod 1211 and the second movable part 123 sleeved on the second screw rod 1212 opposite, the thread rotation direction on the first screw rod 1211 can be opposite to the thread rotation direction on the second screw rod 1212. The above-mentioned reverse movement of the first movable part 122 and the second movable part 123 can be achieved by only setting the thread rotation direction of the first screw rod 1211 to be opposite to the thread rotation direction of the second screw rod 1212, which has a simple structure and is easy to assemble. It is understandable that at this time, the driving member 1213 can be a mechanism that can output circumferential motion, such as a motor 12133.

[0032] In another exemplary embodiment, the thread direction of the first screw rod 1211 may be the same as the thread direction of the second screw rod 1212, and the first screw rod 1211 may be arranged in parallel with the second screw rod 1212. Figure 7The driving member 1213 may include a first output rod 12131 and a second output rod 12132. When the driving member 1213 is in operation, the first output rod 12131 and the second output rod 12132 may rotate in opposite directions. The first screw rod 1211 may be connected to the first output rod 12131 and may rotate with the first output rod 12131. The second screw rod 1212 may be connected to the second output rod 12132 and may rotate with the second output rod 12132, so that the first screw rod 1211 and the second screw rod 1212 may rotate in opposite directions. Since the first screw rod 1211 and the second screw rod 1212 are arranged in parallel, compared to arranging the first screw rod 1211 and the second screw rod 1212 along the same straight line, the first screw rod 1211 and the second screw rod 1212 as a whole can be smaller along the length direction of the first screw rod 1211, thereby reducing the size of the telescopic screen assembly 100 along the length direction of the first screw rod 1211, thereby realizing the miniaturization of the electronic device 10.

[0033] It should be noted that due to the potential for errors during assembly or production, achieving a strictly parallel arrangement is difficult. Therefore, any parallel arrangement in the embodiments of the present application may be considered a parallel arrangement as long as it is within the permissible error range. The permissible error range may be adjusted accordingly based on actual conditions. For example, the permissible error range may be between -10° and 10°, and the embodiments of the present application do not limit this.

[0034] To achieve the aforementioned "first output rod 12131 and second output rod 12132 can rotate in opposite directions when driving member 1213 is in operation," driving member 1213 can include a motor 12133, a first bevel gear 12134, and a second bevel gear 12135. Motor 12133 has an output shaft, first bevel gear 12134 can be fixedly connected to the output shaft of motor 12133, a central axis of second bevel gear 12135 can be parallel to the central axis of first bevel gear 12134, and second bevel gear 12135 can mesh with first bevel gear 12134. Second bevel gear 12135 can be fixedly mounted on one of first output rod 12131 and second output rod 12132, and the output shaft of motor 12133 can be connected to the other of first output rod 12131 and second output rod 12132, so that when motor 12133 is in operation, first output rod 12131 and second output rod 12132 can rotate in opposite directions. The engagement of two bevel gears enables rotation in two opposite directions, which has a simple structure and smooth transmission. Since the bevel gears can be set smaller, the structure of the driving member 1213 can be designed to be smaller, thereby reducing the size of the telescopic screen assembly 100 and realizing miniaturization and lightweighting of the electronic device 10.

[0035] It should be noted that the drive member 1213 is not limited to being able to achieve rotation in two opposite directions using two helical gears. It can also be any other structure capable of achieving rotation in two opposite directions. For example, it can be achieved through belt transmission. Specifically, the drive member 1213 may include a motor, a first transmission wheel, a second transmission wheel, a third transmission wheel, a fourth transmission wheel, and a belt. The first transmission wheel can be fixedly connected to the output shaft of the motor 12133. The first transmission wheel, the second transmission wheel, the third transmission wheel, and the fourth transmission wheel can be spaced apart, and the second transmission wheel and the third transmission wheel can be located on the side of the fourth transmission wheel away from the first transmission wheel. The belt can be sequentially mounted on the first transmission wheel, the second transmission wheel, the fourth transmission wheel, and the third transmission wheel so that the first transmission wheel, the second transmission wheel, and the third transmission wheel rotate in the same direction, and the fourth transmission wheel rotates in the opposite direction to the first transmission wheel, the second transmission wheel, and the third transmission wheel. One of the first output rod 12131 and the second output rod 12132 can be fixedly connected to any one of the first transmission wheel, the second transmission wheel, and the third transmission wheel, and the other of the first output rod 12131 and the second output rod 12132 can be connected to the fourth transmission wheel. Since the belt drive has the effects of smooth movement and convenient assembly, it can ensure the smooth operation of the retractable screen assembly 100 and improve assembly efficiency.

[0036] Please refer again Figure 3 and Figure 4 When the first screw rod 1211 and the second screw rod 1212 are parallel, the plane on which the central axis of the first screw rod 1211 and the central axis of the second screw rod 1212 lie can be parallel to the display surface of the first display portion 111. In this way, the size of the retractable screen assembly 100 in a direction perpendicular to the display surface of the first display portion 111 can be reduced, thereby achieving a lighter and thinner electronic device 10.

[0037] It can be understood that when the first screw rod 1211 is parallel to the second screw rod 1212, the plane where the central axis of the first screw rod 1211 and the central axis of the second screw rod 1212 are located can be perpendicular to the display surface of the first display unit 111. In this way, the size of the telescopic screen assembly 100 in the direction perpendicular to the central axis of the first screw rod 1211 can be reduced to improve the space utilization of the electronic device 10. Of course, the angle between the plane where the central axis of the first screw rod 1211 and the central axis of the second screw rod 1212 are located and the display surface of the first display unit 111 can also be greater than 0° and less than 90°, and the embodiment of the present application does not limit this.

[0038] In order to facilitate the connection between the first movable portion 122 and the first display portion 111 and the connection between the second movable portion 123 and the second display portion 112, the driving unit 121 may further include an isolating member to isolate the first screw rod 1211 from the second screw rod 1212 through the isolating member, thereby further isolating the first movable portion 122 on the first screw rod 1211 from the second movable portion 123 on the second screw rod 1212, thereby facilitating the assembly of the driving structure 120. For details, please refer to Figure 6 The isolation member may include a partition 1214, a first end plate 1215, and a second end plate 1216. The partition 1214 may be parallel to the first screw rod 1211 and located between the first screw rod 1211 and the second screw rod 1212. The first end plate 1215 and the first screw rod 1211 may be located on the same side of the partition 1214 and connected to one end of the partition 1214. The second end plate 1216 and the second screw rod 1212 may be located on the same side of the partition 1214 and connected to the other end of the partition 1214. In this way, the cross-section of the isolation member defined by the partition 1214, the first end plate 1215 and the second end plate 1216 is roughly Z-shaped, so that the first screw rod 1211 and the second screw rod 1212 will not interfere with each other, and when assembling the driving structure 120, the connection between the first screw rod 1211 and the first movable part 122, and the connection between the first movable part 122 and the first display part 111 will not interfere with the connection between the second screw rod 1212 and the second movable part 123, and the connection between the second movable part 123 and the second display part 112.

[0039] Please refer again to Figure 3 When the plane in which the central axis of the first screw rod 1211 and the central axis of the second screw rod 1212 are located is parallel to the display surface of the first display unit 111, in order to prevent the first end plate 1215 from hindering the movement of the first movable part 122 on the first screw rod 1211, the first end plate 1215 can be located on the side of the first screw rod 1211 away from the first display unit 111. In order to prevent the second end plate 1216 from hindering the movement of the second movable part 123 on the second screw rod 1212, the second end plate 1216 can be located between the second screw rod 1212 and the first display unit 111.

[0040] Please refer again Figure 6To ensure that the first movable portion 122 can move on the first screw rod 1211 without rotating with the first screw rod 1211, the drive unit 121 may further include a first guide rod 1217. The first guide rod 1217 may be parallel to the first screw rod 1211, and the first movable portion 122 is also sleeved on the first guide rod 1217 and can move on the first guide rod 1217. In this way, under the restriction of the first guide rod 1217, the first movable portion 122 will not be able to rotate with the first screw rod 1211, but will move relative to the first screw rod 1211 and the first guide rod 1217 under the threaded engagement. It is understandable that a first limiting structure may also be provided between the partition 1214 and the first movable portion 122 or between the first end plate 1215 and the first movable portion 122, so that the first movable portion 122 cannot rotate with the first screw rod 1211 under the restriction of the first limiting structure. For example, the first limiting structure may include a sliding groove extending along the length direction of the first screw rod 1211 and a slider located in the sliding groove. When the first limiting structure is provided between the partition 1214 and the first movable part 122, one of the partition 1214 and the first movable part 122 may be provided with a slider, and the other of the partition 1214 and the first movable part 122 may be provided with a sliding groove.

[0041] Similarly, to ensure that the second movable portion 123 can move on the second screw rod 1212 without rotating with it, the drive unit 121 may further include a second guide rod 1218, which is parallel to the second screw rod 1212. The second movable portion 123 is also sleeved on the second guide rod 1218 and can move on the second guide rod 1218. In this way, under the restriction of the second guide rod 1218, the second movable portion 123 will not rotate with the second screw rod 1212, but will move relative to the second screw rod 1212 and the second guide rod 1218 under the threaded engagement. Similarly, a second limiting structure may be provided between the partition plate 1214 and the second movable portion 123, or between the second end plate 1216 and the second movable portion 123, so that the second movable portion 123 cannot rotate with the second screw rod 1212 under the restriction of the second limiting structure. For example, the second limiting structure may include a slide groove extending along the length direction of the second screw rod 1212 and a slider located in the slide groove. When a second limiting structure is provided between the partition 1214 and the second movable part 123, one of the partition 1214 and the second movable part 123 may be provided with a slider, and the other of the partition 1214 and the second movable part 123 may be provided with a slide groove.

[0042] It should be noted that, since the display surface of the first display portion 111 of the display 110 remains exposed when the display screen 110 switches between the retracted state and the expanded state, that is, the first display portion 111 does not need to be rolled up or folded. Therefore, the first display portion 111 can be either a rigid screen or a flexible screen. However, since the second display portion 112 of the display screen 110 needs to switch between being exposed on the frame 130 or located on the back side of the first display portion 111, it needs to be rolled up or folded. Therefore, the second display portion 112 is preferably a flexible screen.

[0043] Since the flexible screen is relatively soft and easily deformed, the second display portion 112 can be driven by the second movable portion 123 to move relatively smoothly following the second movable portion 123. Figure 4 The retractable screen assembly 100 may further include a push rod 140. The second display portion 112 has a first side 1121 away from the first display portion 111. The push rod 140 may extend along the length direction of the first side 1121 and connect the first side 1121. The connection between the second display portion 112 and the second movable portion 123 may be achieved via the connection between the push rod 140 and the second movable portion 123.

[0044] Specifically, the push rod 140 may be provided with a first connecting member 141, and the second movable portion 123 may be provided with a second connecting member 1231, which may be connected to the first connecting member 141. In an exemplary embodiment, the first connecting member 141 may include one of a protrusion and a slot, and the second connecting member 1231 may include the other of a protrusion and a slot, with the protrusion connected to the slot. The connection between the protrusion and the slot simplifies the connection and improves assembly efficiency.

[0045] When the second display unit 112 is a flexible screen, to ensure consistency between the first and second display units 111, 112, and enhance the user experience, the first display unit 111 may also be a flexible screen. When both the first and second display units 111, 112 are flexible screens, the first and second display units 111, 112 may be directly integrally formed, thereby reducing assembly steps for the first and second display units 111, 112 and improving assembly efficiency.

[0046] In some exemplary embodiments, when the first display portion 111 is a flexible screen, to prevent the first display portion 111 from collapsing and affecting the display effect, the retractable screen assembly 100 may further include a first support plate 150. The first support plate 150 may be attached to the back of the first display portion 111 and connected to the first display portion 111. Preferably, the connection between the first display portion 111 and the first movable portion 122 can be converted into a connection between the first support plate 150 and the first movable portion 122. Since the first support plate 150 has a relatively fixed structure compared to the flexible first display portion 111, the connection is more convenient. Moreover, compared to connecting the first display portion 111 to the first movable portion 122, the connection between the first support plate 150 and the first movable portion 122 can also prevent the first display portion 111 from being directly pulled by the first movable portion 122, thereby reducing the phenomenon of pulling damage to the first display portion 111.

[0047] See also Figure 8 and Figure 9 , the retractable screen assembly 100 may further include a second support plate 160 for supporting the unfolded second display portion 112 to ensure the flatness of the second display portion 112. Preferably, under the support of the first support plate 150 and the second support plate 160, when the display screen 110 is unfolded, the display surface of the first display portion 111 and the display surface of the second display portion 112 may be coplanar. At least one slide groove 151 may be provided on the surface of the first support plate 150 facing the first display portion 111, and the length direction of the slide groove 151 may be parallel to the movement direction of the first movable portion 122. The second support plate 160 may include a first support portion 161 and a second support portion 162 equal in number to the slide groove 151. The first support portion 161 may be connected to the frame 130, and each second support portion 162 may be correspondingly located in a slide groove 151 and connected to the first support portion 161. The setting of the slide groove 151 not only enables the surface of the first support plate 150 facing the first display unit 111 to be flush with the surface of the second support plate 160 facing the first display unit 111, but also reduces the weight of the first support plate 150, thereby achieving lightweighting of the retractable screen assembly 100.

[0048] It should be noted that in order to ensure the smooth expansion or contraction of the second display portion 112, the first support plate 150 has a first side surface 152 close to the second display portion 112, and the sliding groove on the first support plate 150 can penetrate into the first side surface 152 so that the relative sliding between the second support plate 160 and the first support plate 150 can be carried out smoothly.

[0049] In order to guide the sliding of the first support plate 150 relative to the frame 130, a guide block 153 may be provided on the first support plate 150, and a guide groove cooperating with the guide block 153 may be provided on the frame 130, and the guide block 153 may be located in the guide groove.

[0050] The first movable portion 122 and the second movable portion 123 may both be block-shaped structures, and the connection between the first movable portion 122 and the first support plate 150 may be achieved by screw connection, coupling connection of a protrusion and a groove, or the like.

[0051] The number of drive structures 120 can be one or more. Due to limited space within the electronic device 10, the number of drive structures 120 is preferably one. When there is only one drive structure 120, the drive structure 120 can be located in the middle of the frame 130. Specifically, if the dividing line between the first display portion 111 and the second display portion 112 is defined as the first dividing line, the drive structure 120 can be located within the frame 130 and disposed corresponding to the middle of the first dividing line.

[0052] Please refer again Figure 3 The retractable screen assembly 100 may further include a push roller 170, which may be connected to the frame 130. The end of the second display portion 112 away from the first display portion 111 may pass around the push roller 170 and be located on the side where the back of the first display portion 111 is located. When the display screen 110 is expanded or folded, the second display portion 112 may be flattened by the push roller 170 to ensure a smooth surface. The push roller 170 and the second display portion 112 may be designed to have rolling friction to reduce the friction between the second display portion 112 and the push roller 170, making the expansion or folding of the display screen 110 more labor-saving.

[0053] In a second aspect, embodiments of the present application provide an electronic device 10. The electronic device 10 includes the aforementioned retractable screen assembly 100. The electronic device 10 can be any device including a mobile phone, tablet computer, or the like that includes the retractable screen assembly 100, and is lightweight, compact, and easy to assemble.
