Description

Technical Field

[0001] This application belongs to the field of electronic technology, and specifically relates to a rotating screen device. Background Technology

[0002] The display component of the rotating screen device can rotate at different angles to adapt to different viewing postures and perspectives of consumers, so as to better display the images on the display component of the rotating screen device, bring users a brand-new user experience, and meet the viewing and operation needs in different scenarios.

[0003] In related technologies, mechanical structures are generally used to fix the display assembly and the housing assembly, locking the display assembly at the desired angle. For example, locking bolts connect the display assembly and the housing assembly, locking the display assembly at the required angle. Alternatively, matching snap-fit ​​structures are used on the display assembly and housing assembly; when the display assembly rotates to the desired angle, the snap-fit ​​structure engages, locking the display assembly at that angle. However, when it is necessary to rotate the display assembly to another angle, a release operation is required first. This includes removing the locking bolts or pressing the unlocking mechanism to separate the snap-fit ​​structure, releasing the lock on the display assembly and allowing it to rotate again. Thus, each time the display assembly is rotated, an unlocking operation is required before rotating it to the desired angle and then re-locking it, making the rotation operation cumbersome and reducing the ease of use of the rotating screen device. Utility Model Content

[0004] The purpose of this application is to provide a rotating screen device that can solve the problem that the rotation operation of the display screen component of the rotating screen device in the related art is cumbersome and reduces the ease of use of the rotating screen device.

[0005] This application provides a rotating screen device, including a fixed shell assembly, a display screen assembly, and a limiting engagement assembly. The display screen assembly is rotatably connected to the fixed shell assembly, and the limiting engagement assembly includes a roller and a first elastic element.

[0006] One of the fixed housing assembly and the display screen assembly is a first assembly, and the other is a second assembly. The roller is connected to the first assembly through the first elastic member, and the roller can move relative to the first assembly in a direction parallel to the rotation axis of the display screen assembly. The second assembly is provided with at least two limiting grooves, and each limiting groove is distributed along the rotation direction of the display screen assembly. Under the action of the first elastic member, a portion of the roller can extend into the limiting groove, and the roller and the groove wall of the limiting groove are in a limiting engagement in the rotation direction of the display screen assembly.

[0007] In this embodiment, the roller and the limiting groove limit the rotation direction of the display component, thereby locking the display component at the required angle and locking the display component to prevent it from rotating randomly due to gravity or other factors during use. This ensures the stability of the entire rotating screen device during use and allows the user to use the rotating screen device normally.

[0008] Furthermore, as the display assembly rotates from one angle to another under external force, the roller and the limiting groove can automatically separate until part of the roller extends into another limiting groove and engages with it, locking the display assembly at another angle. This eliminates the need for additional unlocking operations when rotating the display assembly, making operation simple and convenient, and effectively improving the ease of use of the rotating screen device.

[0049] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0050] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0051] The rotating screen device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0052] refer to Figures 1-21 The rotating screen device provided in this application embodiment may include a fixed shell assembly 100, a display screen assembly 200, and a limiting and cooperating assembly 600.

[0053] The display screen assembly 200 is rotatably connected to the fixed housing assembly 100, which allows the user to adjust the position of the display screen assembly 200 according to actual needs when using the rotating screen device.

[0054] In some embodiments, the fixed housing assembly 100 may be provided with a first rotating connection portion 111, and the display assembly 200 may be provided with a second rotating connection portion 202. The first rotating connection portion 111 and the second rotating connection portion 202 may be connected by a bearing 500. Specifically, the first rotating connection portion 111 may be connected to the outer ring of the bearing 500, and the second rotating connection portion 202 may be connected to the inner ring of the bearing 500. Furthermore, the first rotating connection portion 111 may be provided with a first protrusion, and the second rotating connection portion 202 may be provided with a second protrusion. In the direction of the rotation axis of the display assembly 200, the first protrusion is matched with the outer ring of the bearing 500, and the second protrusion is matched with the inner ring of the bearing 500. In this way, the first rotating connection portion 111 and the second rotating connection portion 202 may be prevented from moving relative to the bearing 500 along the axial direction, thereby improving the connection stability between the first rotating connection portion 111 and the second rotating connection portion 202 and the bearing 500.

[0055] In an optional embodiment, the fixed housing assembly 100 may include a middle frame 110, a bottom housing 120 connected to the middle frame 110, and a first circuit board assembly 130. A first rotating connection portion 111 is disposed on the side of the middle frame 110 opposite to the bottom housing 120, and the first circuit board assembly 130 is disposed within the middle frame 110. The display assembly 200 may include a display 210, a screen fixing bracket 220, a screen back housing 230, and a second circuit board assembly 240. A second rotating connection portion 202 is disposed on the screen back housing 230, the screen fixing bracket 220 is connected to the screen back housing 230, the display 210 is disposed on the side of the screen fixing bracket 220 opposite to the screen back housing 230, and is connected to the screen fixing bracket 220. The second circuit board assembly 240 may be disposed within the screen fixing bracket 220, and a slot 241 may be provided on the second circuit board assembly 240. The display 210 may be electrically connected to the slot 241 via a wire. The rotating screen device may also include a slip ring 300. The middle frame 110 is provided with a through hole. Part of the slip ring 300 is located inside the middle frame 110 and is electrically connected to the first circuit board assembly 130. The other part of the slip ring 300 passes through the through hole and is electrically connected to the second circuit board assembly 240 through the connecting line 400, thereby realizing the electrical connection between the second circuit board assembly 240 and the first circuit board assembly 130. Specifically, the first circuit board assembly 130 is provided with a first socket, and the stator end of the slip ring 300 can be electrically connected to the first socket via a wire. The second circuit board assembly 240 is provided with a second socket 242, and the first end of the connecting line 400 is electrically connected to the second socket 242, and the second end of the connecting line 400 is electrically connected to the rotor end of the slip ring 300. This enables signal connection between the display screen 210, the first circuit board assembly 130, and the second circuit board assembly 240. Furthermore, the slip ring 300 enables electrical connection between the first circuit board assembly 130 and the second circuit board assembly 240, allowing the second circuit board assembly 240 to maintain electrical connection with the first circuit board assembly 130 as it rotates with the display screen assembly 200.

[0056] Furthermore, the limiting engagement component 600 may include a roller 610 and a first elastic member 620. One of the fixed housing component 100 and the display screen component 200 may be the first component, and the other may be the second component. The roller 610 is connected to the first component via the first elastic member 620, and the roller 610 can move relative to the first component in a direction parallel to the rotation axis of the display screen component 200. The second component may be provided with at least two limiting grooves 103, each of which may be distributed along the rotation direction of the display screen component 200. Under the action of the first elastic member 620, a portion of the roller 610 may extend into the limiting groove 103, and the roller 610 and the groove wall of the limiting groove 103 are in a limiting engagement in the rotation direction of the display screen component 200. In this embodiment, since the second component is provided with at least two limiting grooves 103, the user can rotate the display assembly 200 to the required angle according to their actual needs. Furthermore, the first elastic element 620 always provides a force to the roller 610 in the direction of the limiting groove 103, ensuring a tight fit between the roller 610 and the limiting groove 103. Even after prolonged use or under slight external vibration, the roller 610 is not easily dislodged from the limiting groove 103, ensuring stable positioning of the display assembly 200 at various angles. Here, the design of the roller 610 makes the rotation of the display assembly 200 smoother.

[0057] In this embodiment, the display assembly 200 can be a first assembly, and the fixing housing assembly 100 can be a second assembly. Of course, the display assembly 200 can also be a second assembly, and the fixing housing assembly 100 can also be a first assembly.

[0058] In this embodiment, the roller 610 and the limiting groove 103 limit the rotation direction of the display screen assembly 200, thereby locking the display screen assembly 200 at the required angle and locking the display screen assembly 200 to prevent it from rotating randomly due to gravity or other factors during use. This ensures the stability of the entire rotating screen device during use and allows the user to use the rotating screen device normally.

[0059] Furthermore, during the rotation of the display assembly 200 from one angle to another under the action of external force, the roller 610 and the limiting groove 103 can automatically separate until a portion of the roller 610 extends into another limiting groove 103 and engages with that limiting groove 103, thereby locking the display assembly 200 at another angle. In this way, no additional unlocking operation is required when rotating the display assembly 200, making the operation simple and convenient, and thus effectively improving the ease of use of the rotating screen device.

[0060] Furthermore, in this embodiment of the application, the positioning angle is more accurate than that of the display component 200 being rotated by a motor and positioned by the self-locking of the motor, which is achieved by using the roller 610 to limit the position with the limiting groove 103. Moreover, it does not require the use of algorithms to correct the positioning angle or to perform multiple positioning operations.

[0061] In one alternative embodiment of this application, such as Figure 1 , Figure 2 and Figure 12 As shown, the rotating screen device may further include a first limiting member 700 and a second limiting member 800. Both the first limiting member 700 and the second limiting member 800 may be disposed on the second component. The first limiting member 700 and the second limiting member 800 may be distributed along the rotation direction of the display screen component 200. Furthermore, at least two limiting grooves 103 may include a first limiting groove 1031 and a second limiting groove 1032. The first limiting groove 1031 may be disposed on the first limiting member 700, and the second limiting groove 1032 may be disposed on the second limiting member 800.

[0062] The roller 610 can roll between the first limiting member 700 and the second limiting member 800, such as Figure 12 and Figure 13 As shown, the first limiting member 700 may be provided with a first limiting part 740, such as... Figure 12 and Figure 14 As shown, the second limiting member 800 may be provided with a second limiting part 840, the first limiting part 740 may protrude from the opening of the first limiting groove 1031, the second limiting part 840 may protrude from the opening of the second limiting groove 1032, and the first limiting groove 1031 and the second limiting groove 1032 are both located between the first limiting part 740 and the second limiting part 840.

[0063] When a portion of the roller 610 extends into the first limiting groove 1031, the roller 610 and the first limiting part 740 are engaged in a limiting engagement in the rotational direction of the display assembly 200. This prevents the roller 610 from continuing to roll towards the first limiting part 740 and dislodging from the first limiting groove 1031. When a portion of the roller 610 extends into the second limiting groove 1032, the roller 610 and the second limiting part 840 are engaged in a limiting engagement in the rotational direction of the display assembly 200. This prevents the roller 610 from continuing to roll towards the second limiting part 840 and dislodging from the second limiting groove 1032.

[0064] In this embodiment, since the first limiting part 740 protrudes from the opening of the first limiting groove 1031 and the second limiting part 840 protrudes from the opening of the second limiting groove 1032, when the roller 610 is embedded in the first limiting groove 1031, it can form a reliable limiting engagement with the first limiting part 740 in the rotation direction of the display assembly 200, and when the roller 610 is embedded in the second limiting groove 1032, it can form a reliable limiting engagement with the second limiting part 840 in the rotation direction of the display assembly 200. In this way, on the one hand, the roller 610 is less likely to come out of the first limiting groove 1031 or the second limiting groove 1032, improving the stability of the positioning of the display assembly 200. On the other hand, the first limiting part 740 can prevent the display assembly 200 from continuing to rotate along the rotation direction, which is the direction from the second limiting member 800 to the first limiting member 700. The second limiting part 840 can also prevent the display assembly 200 from continuing to rotate along the rotation direction, which is the direction from the first limiting member 700 to the second limiting member 800. Thus, the limiting effect of the first limiting part 740 and the second limiting part 840 can limit the rolling stroke of the roller 610, thereby limiting the rotation angle range of the display assembly 200.

[0065] In other embodiments, the first limiting member 700 may not have the first limiting portion 740, and the second limiting member 800 may not have the second limiting portion 840. Furthermore, the second component may have multiple limiting grooves 103. Under the action of the first elastic member 620, portions of the roller 610 can extend into each limiting groove 103, and the roller 610 and the groove wall of each limiting groove 103 are respectively engaged in a limiting engagement in the rotation direction of the display assembly 200, so that the display assembly 200 can be locked at different angles.

[0066] In some embodiments, such as Figures 1-4 As shown, the angle between the line connecting the center of the first limiting groove 1031 and the rotation center of the display assembly 200, and the line connecting the center of the second limiting groove 1032 and the rotation center of the display assembly 200, can be 90°, so that the rotation angle range of the display assembly 200 is 0-90°. For example, when a portion of the roller 610 extends into the first limiting groove 1031, the display assembly 200 is in a landscape state; when a portion of the roller 610 extends into the second limiting groove 1032, the display assembly 200 is in a portrait state. Thus, by rolling the roller 610 between the first limiting groove 1031 and the second limiting groove 1032, the landscape and portrait modes of the display assembly 200 can be switched.

[0067] In optional embodiments, such as Figure 13As shown, the first limiting member 700 may include a first arcuate portion 710 and a first guide portion 720 connected to the first arcuate portion 710, and the first arcuate portion 710 may form a first limiting groove 1031. Figure 14 As shown, the second limiting member 800 may include a second arcuate portion 810 and a second guide portion 820 connected to the second arcuate portion 810. The second arcuate portion 810 may form a second limiting groove 1032.

[0068] like Figure 10 As shown, the second component may also be provided with a roller rolling surface 101, on which the roller 610 can roll. Furthermore, the end of the first guide portion 720 away from the first arc-shaped portion 710 may be flush with the roller rolling surface 101 or located on the side of the roller rolling surface 101 away from the roller 610. The end of the second guide portion 820 away from the second arc-shaped portion 810 may be flush with the roller rolling surface 101 or located on the side of the roller rolling surface 101 away from the roller 610. In this embodiment, the first guide portion 720 and the second guide portion 820 can provide a smooth transition path for the roller 610 to roll between different limiting grooves 103. When the roller 610 rolls from the roller rolling surface 101 to the limiting groove 103 or from the limiting groove 103 to the roller rolling surface 101, the first guide portion 720 or the second guide portion 820 can guide the roller 610 to smoothly enter and exit the first limiting groove 1031 or the second limiting groove 1032. Since the first guide portion 720 is away from the end of the first arc-shaped portion 710 and the second guide portion 820 is away from the second arc-shaped portion 810, One end of the roller is flush with the roller rolling surface 101 or located on the side of the roller rolling surface 101 away from the roller 610. This can prevent the roller 610 from getting stuck due to sudden height differences or obstacles, making the rotation operation of the display assembly 200 smoother. It can also make the contact between the roller 610 and the first guide part 720, the second guide part 820 and the roller rolling surface 101 more natural during the rolling process, reducing unnecessary friction and resistance, further improving the smoothness of the roller 610's rolling, and effectively reducing the force required for the user to rotate the display assembly 200.

[0069] In other embodiments, the first limiting member 700 may not include the first guide portion 720, and the second limiting member 800 may not include the second guide portion 820. For example, the first limiting member 700 may only include the first arc-shaped portion 710, and the second limiting member 800 may only include the second arc-shaped portion 810.

[0070] In an optional embodiment, both the first limiting member 700 and the second limiting member 800 can be rotatably connected to the second component. Both the first limiting member 700 and the second limiting member 800 can rotate between an initial position and a limiting position. When a portion of the roller 610 extends into the first limiting groove 1031, the first limiting member 700 rotates to the limiting position. When a portion of the roller 610 extends into the second limiting groove 1032, the second limiting member 800 rotates to the limiting position.

[0071] like Figure 2 As shown, when the first limiting member 700 is in the initial position, the end of the first guide portion 720 opposite to the first arc-shaped portion 710 is flush with the roller rolling surface 101 or located on the side of the roller rolling surface 101 opposite to the roller 610; as Figure 1 As shown, when the second limiting member 800 is in its initial position, the end of the second guide portion 820 opposite to the second arc-shaped portion 810 is flush with the roller rolling surface 101 or located on the side of the roller rolling surface 101 opposite to the roller 610. This arrangement allows the roller 610 to smoothly enter the first limiting groove 1031 or the second limiting groove 1032 when it rolls from the roller rolling surface 101 into the first limiting groove 1031 or the second limiting groove 1032.

[0072] like Figure 1 As shown, when the first limiting member 700 is in the limiting position, one end of the first guide portion 720 away from the first arc-shaped portion 710 protrudes from the roller rolling surface 101 in the direction from the roller 610 to the first elastic member 620; as Figure 2 As shown, when the second limiting member 800 is in the limiting position, the end of the second guide portion 820 opposite to the second arc-shaped portion 810 protrudes from the roller rolling surface 101 in the direction from the roller 610 to the first elastic member 620. With this configuration, when a portion of the roller 610 extends into the first limiting groove 1031 or the second limiting groove 1032, the first limiting member 700 or the second limiting member 800 rotates to the limiting position. At this time, the first guide portion 720 or the second guide portion 820 protrudes from the roller rolling surface 101, making the limiting of the roller 610 in the first limiting groove 1031 or the second limiting groove 1032 more reliable. The first guide portion 720 or the second guide portion 820 can block the roller 610 in the opposite direction of the rotation direction of the display assembly 200, thereby limiting the roller 610 from rolling backward and ensuring that the display assembly 200 is stably locked at the required angle, thus meeting the user's need for fixed angle of the display 210 in different usage scenarios.

[0073] In other embodiments, both the first limiting member 700 and the second limiting member 800 may not be rotatably connected to the second component.

[0074] In optional embodiments, such as Figures 12-14 As shown, the rotating screen device may further include a second elastic element 900 and a third elastic element 1000. The two ends of the second elastic element 900 can be connected to the first guide portion 720 and the second component, respectively. The second elastic element 900 can drive the first limiting member 700 to return to its initial position. The two ends of the third elastic element 1000 can be connected to the second guide portion 820 and the second component, respectively. The third elastic element 1000 can drive the second limiting member 800 to return to its initial position. In this embodiment, the second elastic element 900 or the third elastic element 1000 can automatically drive the first limiting member 700 or the second limiting member 800 to return to its initial position after the corresponding limiting member completes its limiting action. For example, when the roller 610 disengages from the first limiting groove 1031, the second elastic element 900 will cause the first limiting member 700 to rotate back to its initial position, preparing for the next limiting action. Similarly, the third elastic element 1000 will also cause the second limiting member 800 to reset, ensuring that the device can operate continuously and stably.

[0075] In other embodiments, the rotating screen device may also exclude the second elastic element 900 and the third elastic element 1000. For example, the first limiting element 700 or the second limiting element 800 may return to their initial position under their own gravity.

[0076] In optional embodiments, such as Figure 12 and Figure 13 As shown, one of the first guide portion 720 and the second component may be provided with a first limiting protrusion 721, and the other may be provided with a first groove 107. The first limiting protrusion 721 and the first groove 107 are disposed opposite to each other. The first part of the second elastic member 900 is sleeved on the outside of the first limiting protrusion 721, and the second part of the second elastic member 900 is located in the first groove 107 and connected to the bottom wall of the first groove 107. In this embodiment, the first groove 107 and the first limiting protrusion 721 provide an accurate installation position and positioning reference for the second elastic member 900. Furthermore, the first limiting protrusion 721 and the first groove 107 can prevent the second elastic member 900 from displacing radially, thereby effectively preventing the second elastic member 900 from loosening or falling off during device operation, ensuring that the second elastic member 900 can stably drive the first limiting member 700 to return to its initial position.

[0077] Of course, the first guide portion 720 and the second component may not have the first limiting protrusion 721 and the first groove 107 provided.

[0078] like Figure 12 and Figure 14As shown, one of the second guide portion 820 and the second component is provided with a second limiting protrusion 821, and the other is provided with a second groove 108. The second limiting protrusion 821 and the second groove 108 are arranged opposite to each other. The first part of the third elastic member 1000 is sleeved on the second limiting protrusion 821, and the second part of the third elastic member 1000 is located in the second groove 108 and connected to the bottom wall of the second groove 108. In this embodiment, the second groove 108 and the second limiting protrusion 821 provide an accurate installation position and positioning reference for the third elastic member 1000. Furthermore, the second limiting protrusion 821 and the second groove 108 can prevent the third elastic member 1000 from displacing radially, thereby effectively preventing the third elastic member 1000 from loosening or falling off during device operation, ensuring that the third elastic member 1000 can stably drive the second limiting member 800 to return to its initial position.

[0079] Of course, the second guide portion 820 and the second component may not have the second limiting protrusion 821 and the second groove 108 provided.

[0080] Optionally, such as Figure 12 As shown, the second component may also be provided with a first support surface 109 and a second support surface 1010. The first support surface 109 can limit the end of the first guide portion 720 that is away from the first arc-shaped portion 710, so as to limit the rotation angle of the first limiting member 700. The second support surface 1010 can limit the end of the second guide portion 820 that is away from the second arc-shaped portion 810, so as to limit the rotation angle of the second limiting member 800.

[0081] Here, the first groove 107 can be disposed on the first support surface 109, and the second groove 108 can be disposed on the second support surface 1010.

[0082] In optional embodiments, such as Figures 12-14As shown, the first limiting member 700 may further include a first connecting portion 730, and the second limiting member 800 may further include a second connecting portion 830. The first arc-shaped portion 710 may be connected to the first guide portion 720 through the first connecting portion 730, and the second arc-shaped portion 810 may be connected to the second guide portion 820 through the second connecting portion 830. Both the first connecting portion 730 and the second connecting portion 830 are rotatably connected to the second component. With this configuration, since the first arc-shaped portion 710 is connected to the first guide portion 720 through the first connecting portion 730, and the second arc-shaped portion 810 is connected to the second guide portion 820 through the second connecting portion 830, the first connecting portion 730 and the second connecting portion 830 are both located in the middle of the entire structure of the first limiting member 700 and the second limiting member 800. When the first connecting portion 730 and the second connecting portion 830 are rotatably connected to the second component, it is equivalent to realizing the rotatable connection between the middle of the first limiting member 700 and the second limiting member 800 and the second component. This connection method allows the first limiting member 700 and the second limiting member 800 to rotate around the middle as an axis, thereby more flexibly realizing the switching between the initial position and the limiting position to meet the functional requirements of limiting and releasing the roller 610.

[0083] Furthermore, along the direction from the second elastic member 900 to the first guide portion 720, the first connecting portion 730 protrudes from the opening of the first limiting groove 1031 and the first guide portion 720. This configuration allows the first connecting portion 730 to form an additional blocking structure at the opening of the first limiting groove 1031. Consequently, when the roller 610 attempts to disengage from the first limiting groove 1031, it will be blocked by the first connecting portion 730, increasing the difficulty for the roller 610 to disengage from the first limiting groove 1031, thereby improving the positioning effect of the display assembly 200.

[0084] Of course, along the direction from the second elastic member 900 to the first guide portion 720, the first connecting portion 730 may not protrude from the opening of the first limiting groove 1031 and the first guide portion 720.

[0085] Along the direction from the third elastic member 1000 to the second guide portion 820, the second connecting portion 830 protrudes from the opening of the second limiting groove 1032 and the second guide portion 820. This configuration allows the second connecting portion 830 to form an additional blocking structure at the opening of the second limiting groove 1032. Consequently, when the roller 610 attempts to disengage from the second limiting groove 1032, it will be blocked by the second connecting portion 830, increasing the difficulty for the roller 610 to disengage from the second limiting groove 1032, thereby improving the positioning effect of the display assembly 200.

[0086] Of course, along the direction from the third elastic member 1000 to the second guide portion 820, the second connecting portion 830 may not protrude from the opening of the second limiting groove 1032 and the second guide portion 820.

[0087] In optional embodiments, such as Figure 12 As shown, the second component may also be provided with a first rotating shaft 140 and a second rotating shaft 150, such as... Figure 13 As shown, the first connecting portion 730 may be provided with a first rotating claw 750, which can be engaged with the first rotating shaft 140, and the first rotating claw 750 and the first rotating shaft 140 can rotate relative to each other, such as... Figure 14 As shown, the second connecting part 830 may be provided with a second rotating claw 850, which can be locked onto the second rotating shaft 150, and the second rotating claw 850 and the second rotating shaft 150 can rotate relative to each other. This arrangement facilitates the assembly and disassembly of the first limiting member 700 and the second limiting member 800.

[0088] In other embodiments, the first connecting portion 730 may be provided with a first through hole, the first rotating shaft 140 may be located in the first through hole, the second connecting portion 830 may be provided with a second through hole, and the second rotating shaft 150 may be located in the second through hole.

[0089] In optional embodiments, such as Figure 12 As shown, the second component may also be provided with a first clearance groove 105 and a second clearance groove 106. When a portion of the roller 610 extends into the first limiting groove 1031, a portion of the first arc-shaped portion 710 extends into the first clearance groove 105; when a portion of the roller 610 extends into the second limiting groove 1032, a portion of the second arc-shaped portion 810 extends into the second clearance groove 106. In this embodiment, the first clearance groove 105 and the second clearance groove 106 can provide dedicated accommodating space for the first arc-shaped portion 710 and the second arc-shaped portion 810. During device operation, this can prevent these components from rubbing or colliding with other parts of the second component, thereby protecting the first arc-shaped portion 710 and the second arc-shaped portion 810. This helps extend the service life of the first limiting member 700 and the second limiting member 800 and improves the reliability of the rotating screen device.

[0090] Of course, the second component may also omit the first clearance slot 105 and the second clearance slot 106.

[0091] In another alternative embodiment of this application, such as Figure 3 and Figure 4As shown, the second component may also be provided with a roller rolling surface 101, on which the roller 610 can roll, and a limiting groove 103 may be provided on the roller rolling surface 101. Here, the roller rolling surface 101 may be the bottom wall of the roller track groove 102 described below. In this embodiment, the limiting groove 103 is directly provided on the roller rolling surface 101, eliminating the need for additional limiting components to support the limiting groove 103, reducing the number of parts, which is beneficial for reducing manufacturing and assembly costs, and also makes the overall structure simpler; at the same time, since the limiting groove 103 is located on the roller rolling surface 101, the cooperation between the roller 610 and the limiting groove 103 during rolling is more direct and stable. Compared with the method of indirectly limiting the roller 610 through limiting components, the intermediate links are reduced, which can more effectively prevent the roller 610 from shaking or deviating during the limiting process due to the instability of the limiting component structure, thereby improving the stability and reliability of the entire system.

[0092] In other embodiments, a limiting member is provided on the second component, and a limiting groove 103 is provided on the limiting member.

[0093] In optional embodiments, such as Figure 3 , Figure 4 , Figures 17-21 As shown, a slide groove 104 may be provided on one of the first component and the second component, and a stop portion 250 may be provided on the other component. The slide groove 104 may be an arc-shaped structure, and the axis of the slide groove 104 may coincide with the rotation axis of the display assembly 200. The stop portion 250 may slide and engage with the slide groove 104. A first stop surface 1041 and a second stop surface 1042 may be provided on both sides of the slide groove 104 in the rotation direction of the display assembly 200, respectively.

[0094] At least two limiting grooves 103 may include a first limiting groove 1031 and a second limiting groove 1032. The roller 610 can roll between the first limiting groove 1031 and the second limiting groove 1032. When a portion of the roller 610 extends into the first limiting groove 1031, the stop portion 250 and the first stop surface 1041 engage in a stop engagement in the rotation direction of the display assembly 200. When a portion of the roller 610 extends into the second limiting groove 1032, the stop portion 250 and the second stop surface 1042 engage in a stop engagement in the rotation direction of the display assembly 200.

[0095] With this configuration, when the roller 610 rolls between different limiting grooves 103, the stop part 250 will cooperate with the stop surface at different positions of the slide groove 104 to limit the angle range of the display assembly 200 during rotation, so that the display assembly 200 can only rotate within the specified angle, ensuring the accuracy and controllability of the rotation of the display assembly 200, so as to meet the specific requirements of the angle of the display 210 under different usage scenarios.

[0096] In other embodiments, the slide groove 104 and the stop portion 250 may not be provided on either the first component or the second component. Furthermore, the second component may be provided with multiple limiting grooves 103. Under the action of the first elastic member 620, portions of the roller 610 can extend into each limiting groove 103, and the roller 610 and the groove wall of each limiting groove 103 are respectively engaged in a limiting engagement in the rotation direction of the display assembly 200, so that the display assembly 200 can be locked at different angles.

[0097] In an optional embodiment, the limiting groove 103 can be an arc-shaped groove. When part of the roller 610 extends into the arc-shaped groove, the center of the arc-shaped groove coincides with the rotation axis of the roller 610. This configuration allows the roller 610 to achieve a large-area contact with the groove wall of the arc-shaped groove. Compared to the case where the center of the arc-shaped groove does not coincide with the rotation axis of the roller 610, this ensures that the roller 610 and the groove wall of the arc-shaped groove remain in close contact during the contact process. This allows the roller 610 to be restricted by the groove wall of the arc-shaped groove in all directions, thereby effectively preventing the roller 610 from shifting left or right or wobbling in the limiting groove 103, thus effectively improving the limiting accuracy and stability.

[0098] Of course, when part of the roller 610 extends into the arc-shaped groove, the center of the arc-shaped groove and the rotation axis of the roller 610 may not coincide. Alternatively, the limiting groove 103 may not be an arc-shaped groove.

[0099] In optional embodiments of this application, such as Figure 8As shown, the limiting and mating assembly 600 may further include a roller bracket 630, with the roller 610 rotatably connected to the roller bracket 630. The roller bracket 630 may include a first fixing part 631, a second fixing part 632, and a third fixing part 633. The second fixing part 632 may be arranged around the first fixing part 631. The first fixing part 631 and the second fixing part 632 may be connected through the third fixing part 633. Furthermore, a mounting groove 634 may be formed between the first fixing part 631, the second fixing part 632, and the third fixing part 633. The first fixing part 631 may be slidably connected to the first component. The first elastic member 620 may be sleeved on the first fixing part 631, with one end of the first elastic member 620 connected to the first component and the other end of the first elastic member 620 located in the mounting groove 634 and connected to the third fixing part 633. In this embodiment, the sliding connection between the first fixing part 631 and the first component limits the movement direction of the roller 610, allowing it to move parallel to the rotation axis of the display assembly 200. This prevents the roller 610 from deviating from the rotation axis of the display assembly 200 when entering or exiting the limiting groove 103, thus preventing the roller 610 from properly engaging with the groove wall of the limiting groove 103. Furthermore, the first fixing part 631 and the second fixing part 632 limit the first elastic member 620, ensuring it remains in the correct position during operation and preventing displacement that could affect the user experience.

[0100] In other embodiments, the limiting and engaging component 600 may not include the roller bracket 630. For example, the roller 610 may be directly connected to the first component via the first elastic member 620.

[0101] In optional embodiments, such as Figure 8 As shown, the limiting and mating assembly 600 may further include a roller connector 650. The roller 610 can be connected to the roller bracket 630 via the roller connector 650. The roller connector 650 may include a connecting shaft 651 and a bent portion 652 connected to the connecting shaft 651. The bent portion 652 is connected to the roller bracket 630, and the roller 610 can be rotatably mounted on the connecting shaft 651. To prevent the roller 610 from moving axially along the connecting shaft 651, two roller limiting ribs 653 may be provided on the connecting shaft 651. The two roller limiting ribs 653 are located on both sides of the roller 610 and engage with the roller 610 in an axial limiting fit along the connecting shaft 651. It should be noted that the roller limiting ribs 653 do not affect the rotation of the roller 610 around the connecting shaft 651.

[0102] In optional embodiments, such as Figure 8As shown, the limiting engagement assembly 600 may further include a limiting bracket 640, which can be connected to the end of the first fixing part 631 opposite to the roller 610. In the direction from the first fixing part 631 to the roller 610, the limiting bracket 640 can engage with the first assembly in a limiting engagement. With this configuration, the limiting bracket 640 and the first assembly can precisely limit the movement range of the roller bracket 630 and the roller 610 in the direction from the first fixing part 631 to the roller 610. This ensures that the roller 610 moves within a specified stroke in a direction parallel to the rotation axis of the display assembly 200, preventing the roller 610 from exceeding the allowable range and avoiding interference with the second assembly due to excessive movement of the roller 610, which would prevent it from rolling.

[0103] In other embodiments, the limiting engagement component 600 may also exclude the limiting bracket 640.

[0104] Optionally, the limiting bracket 640 may be provided with a connecting hole for connection with the first fixing part 631, specifically, as shown in the example. Figure 8 As shown, the limiting bracket 640 can be connected to the connecting hole via the fastener 660. Here, the fastener 660 can be a screw, and the connecting hole can be a threaded hole.

[0105] like Figure 11 As shown, one of the limiting bracket 640 and the roller bracket 630 can be provided with a positioning post 232, and the other can be provided with a positioning hole 642. The positioning post 232 is located inside the positioning hole 642, and the positioning hole 642 is eccentrically positioned with respect to the connection hole. This configuration allows for accurate positioning of the connection between the limiting bracket 640 and the roller bracket 630 during installation, preventing mistaken connections and facilitating quick and accurate assembly of the two components. Simultaneously, the cooperation of the positioning post 232 and the positioning hole 642 can, to a certain extent, limit the relative movement of the limiting bracket 640 and the roller bracket 630 in a direction perpendicular to the rotation axis of the display assembly 200, thereby improving the connection stability between the limiting bracket 640 and the roller bracket 630.

[0106] Of course, the positioning pin 232 and positioning hole 642 may not be provided on the limit bracket 640 and the roller bracket 630.

[0107] Optionally, such as Figure 11As shown, at least one limiting hole 643 may be provided on one of the limiting bracket 640 and the first component, and at least one limiting post 233 may be provided on the other. The limiting post 233 can slide with the limiting hole 643, and the limiting post 233 and the limiting hole 643 are limited in the direction perpendicular to the rotation axis of the display assembly 200. In this embodiment, the limiting post 233 and the limiting hole 643 are limited in the direction perpendicular to the rotation axis of the display assembly 200, which can effectively prevent relative movement between the limiting bracket 640 and the first component in this direction, and further ensure that the roller 610 is not prone to shaking or deflection in the direction perpendicular to the rotation axis of the display assembly 200, thereby improving the stability of the roller 610.

[0108] Of course, the limiting post 233 and the limiting hole 643 may not be provided on the limiting bracket 640 and the first component.

[0109] Further optional, such as Figure 11 As shown, at least two limiting holes 643 may be provided on one of the limiting bracket 640 and the first component, and at least two limiting posts 233 may be provided on the other. The at least two limiting holes 643 may include a first limiting hole 6431 and a second limiting hole 6432, and the at least two limiting posts 233 may include a first limiting post 2331 and a second limiting post 2332. The first limiting post 2331 may slide with the first limiting hole 6431, and in a direction perpendicular to the rotation axis of the display assembly 200, the first limiting post 2331 may limit the engagement with the first limiting hole 6431. The second limiting post 2332 may slide with the second limiting hole 6432, and in a direction perpendicular to the rotation axis of the display assembly 200, the second limiting post 2332 may limit the engagement with the second limiting hole 6432. This configuration allows for the restriction of the relative movement between the limiting bracket 640 and the first component from multiple positions, thereby more comprehensively constraining the position of the roller 610 in the direction perpendicular to the rotation axis of the display assembly 200, thus reducing the wobbling of the roller 610 in this direction and further improving the stability of the roller 610.

[0110] Of course, one of the limiting bracket 640 and the first component may be provided with only one limiting hole 643, and the other may be provided with only one limiting post 233.

[0111] In addition, such as Figure 11As shown, the cross-sectional areas of the first limiting hole 6431 and the second limiting hole 6432 in the direction of the rotation axis of the display assembly 200 can be different, and the cross-sectional areas of the first limiting post 2331 and the second limiting post 2332 in the direction of the rotation axis of the display assembly 200 can also be different. This arrangement ensures that the first limiting post 2331 and the second limiting post 2332 can only be inserted into their respective matching first limiting holes 6431 and 6432, thus preventing mistaken insertion and facilitating quick and accurate assembly of the two components by the installer. In this embodiment, when the first limiting hole 6431 and the second limiting hole 6432 are circular holes, and when the first limiting post 2331 and the second limiting post 2332 are cylindrical, the diameters of the first limiting hole 6431 and the second limiting hole 6432 are different, and the diameters of the first limiting post 2331 and the second limiting post 2332 are different.

[0112] Of course, the cross-sectional areas of the first limiting hole 6431 and the second limiting hole 6432 in the direction of the rotation axis of the display assembly 200 can also be the same, and the cross-sectional areas of the first limiting post 2331 and the second limiting post 2332 in the direction of the rotation axis of the display assembly 200 can also be the same.

[0113] In optional embodiments, such as Figure 8 As shown, the first component may be provided with a connecting support portion 231, which may be provided with a sliding hole. The first fixing portion 631 may be located in the sliding hole and slide in cooperation with the sliding hole. The limiting bracket 640 may be provided with a mating groove 641, and a portion of the connecting support portion 231 may be located in the mating groove 641. The connecting support portion 231 and the mating groove 641 are limited in cooperation with the groove wall in the direction perpendicular to the rotation direction of the display assembly 200. Furthermore, the connecting support portion 231 and the groove wall of the mating groove 641 are limited in cooperation with the groove wall in the direction from the roller 610 to the first fixing portion 631. This configuration can prevent the roller 610 from wobbling relative to the first component in the direction perpendicular to the rotation axis of the display assembly 200 when it moves in a direction parallel to the rotation axis of the display assembly 200. This can further improve the stability of the roller 610, thereby improving the smoothness and comfort of the user's rotation operation and enhancing the user's operating experience.

[0114] Of course, the limiting bracket 640 may not have a mating groove 641.

[0115] Optionally, such as Figure 17 and Figure 18 As shown, the first component is provided with a mounting hole 201, and the roller bracket 630 is slidably disposed within the mounting hole 201. Here, the mounting hole 201 is provided in the connecting support portion 231.

[0116] In optional embodiments, such as Figure 3 and Figure 4 As shown, the second component may be provided with a roller track groove 102. The axis of the roller track groove 102 may coincide with the rotation axis of the display screen component 200. A portion of the roller 610 may be located in the roller track groove 102 and may roll along the roller track groove 102. The roller 610 and the groove wall of the roller track groove 102 are in radial upper limit engagement with the roller track groove 102. Furthermore, each limiting groove 103 is located in the roller track groove 102. This configuration provides a clear trajectory for the scroll wheel 610, ensuring it can only roll along the scroll wheel track groove 102. This guarantees that the scrolling direction of the scroll wheel 610 is consistent with the rotation direction of the display assembly 200. Simultaneously, the scroll wheel 610 and the groove wall of the scroll wheel track groove 102 engage at the upper radial limit of the groove, restricting the scroll wheel 610's movement in a direction perpendicular to its scrolling direction. This effectively prevents the scroll wheel 610 from wobbling or deviating during scrolling, improving the stability of its movement and consequently enhancing the smoothness of the entire display assembly 200 during rotation. Here, each limiting groove 103 can be formed on the bottom wall of the scroll wheel track groove 102.

[0117] In other embodiments, the roller track groove 102 may not be provided on the second component.

[0118] In one embodiment of this application, such as Figure 1 As shown, when the display screen 210 is in landscape mode, that is, when the display screen assembly 200 is at 90° relative to the fixed housing assembly 100, the roller 610 is engaged with the first limiting groove 1031. At this time, the second elastic member 900 is in a stretched state. Simultaneously, under the action of the first elastic member 620 (or under the combined action of the first elastic member 620 and the roller 610), the first arc-shaped portion 710 of the first limiting member 700 is pressed by the roller 610, so that the side of the first arc-shaped portion 710 away from the roller 610 is in close contact with the bottom of the first clearance groove 105. In addition, the first limiting portion 740 on the first limiting member 700 can limit the left side of the roller 610 (that is, the side away from the second limiting member 800), ensuring that the roller 610 cannot continue to rotate counterclockwise relative to the first limiting member 700, thus preventing the display screen assembly 200 from tilting in landscape mode and affecting the user's visual experience.

[0119] During the process of switching the display screen 210 from landscape mode to portrait mode, the roller 610 gradually moves away from the first arc-shaped portion 710, that is, gradually disengages from the first limiting groove 1031. When the roller 610 completely moves away from the first arc-shaped portion 710, the roller 610 contacts the first connecting portion 730. At this time, the first elastic member 620 is in a state of maximum compression, and the external force applied to the display screen assembly 200 is at its maximum, thus breaking the landscape mode of the display screen assembly 200. Continuing to apply external force causes the display screen assembly 200 to rotate clockwise, and the roller 610 begins to roll along the first guide portion 720. The second elastic member 900 returns to its initial state (the state when the first limiting member 700 is in its initial position, i.e., the second elastic member 900 returns to its original deformation) until the roller 610 completely separates from the first guide portion 720. After the roller 610 separates from the first guide portion 720, the first elastic member 620 also returns to its original deformation.

[0120] As the display screen 210 rotates to the portrait mode, the roller 610 gradually begins to contact the second guide portion 820. When the roller 610 rolls to the top of the second connecting portion 830, the external force applied to the display screen assembly 200 is at its maximum to ensure that the display screen 210 reaches the portrait mode, and the compression of the first elastic member 620 reaches its maximum. Continuing to rotate clockwise, the roller 610 gradually begins to engage with the second limiting groove 1032. At this time, the second limiting member 800 gradually rotates to the limiting position, causing the end of the second guide portion 820 away from the second arc-shaped portion 810 to gradually lift up, and causing the third elastic member 1000 to gradually stretch until the roller 610 is completely in contact with the groove wall of the second limiting groove 1032, indicating that the display screen 210 has switched to the portrait mode.

[0121] like Figure 2As shown, when the display screen 210 is in portrait mode, that is, when the display screen assembly 200 is at 0° relative to the fixed housing assembly 100, the roller 610 is fixed in place with the second arc-shaped part 810. At this time, the side of the second arc-shaped part 810 away from the roller 610 contacts the bottom of the second clearance groove 106. At the same time, under the action of the first elastic member 620 (or under the combined action of the first elastic member 620 and the weight of the roller 610), the first arc-shaped part 710 is pressed by the roller 610, so that the side of the second arc-shaped part 810 away from the roller 610 contacts the bottom of the second clearance groove 106. At this time, the third elastic member 1000 is in the maximum tension state, and the end of the second guide part 820 of the second limiting member 800 away from the second arc-shaped part 810 is raised to restrict the roller 610 from rolling toward the first limiting member 700, thereby restricting the display screen 210 from rotating in the direction of the landscape mode. In addition, the second limiting part 840 of the second limiting member 800 can limit the right side of the roller 610 (that is, the side of the roller 610 away from the first limiting member 700) to ensure that the roller 610 cannot continue to roll clockwise relative to the second limiting member 800, thereby preventing the display screen 210 from tilting in the portrait state and affecting the user's visual experience.

[0122] During the process of switching the display screen 210 from portrait mode to landscape mode, the scroll wheel 610 gradually moves away from the second arc-shaped portion 810. When the scroll wheel 610 completely moves away from the second arc-shaped portion 810, that is, when the scroll wheel 610 contacts the highest point of the second connecting portion 830, the compression of the first elastic member 620 is at its maximum. At this time, the external force applied to the display screen assembly 200 is at its maximum, thus breaking the portrait mode of the display screen assembly 200. Continuing to apply external force causes the display screen assembly 200 to rotate counterclockwise, and the scroll wheel 610 begins to roll along the second guide portion 820 until the two separate. When the scroll wheel 610 separates from the second guide portion 820, the third elastic member 1000 returns to its original deformation, and the first elastic member 620 also returns to its original deformation.

[0123] When the display screen 210 approaches the landscape position, that is, when the display screen 210 is about to switch to the landscape position, the scroll wheel 610 begins to contact the first guide portion 720. When the scroll wheel 610 is at the top of the first connecting portion 730, the external force applied to the display screen assembly 200 is at its maximum to ensure that the display screen 210 reaches the landscape position, and the compression of the first elastic member 620 is at its maximum at this time. Continuing to rotate counterclockwise, the scroll wheel 610 gradually begins to engage with the first arc-shaped portion 710, the first limiting member 700 gradually rotates to the limiting position, and the end of the first guide portion 720 away from the first arc-shaped portion 710 gradually tilts upward, causing the second elastic member 900 to be gradually stretched until the scroll wheel 610 and the first arc-shaped portion 710 are completely in contact, indicating that the display screen 210 has switched to the landscape position.

[0124] In another embodiment of this application, such as Figure 3As shown, when the display screen 210 is in landscape mode, under the action of the first elastic member 620 (or under the combined action of the first elastic member 620 and the gravity of the roller 610), the roller 610 is limited by the first limiting groove 1031. At this time, the stop part 250 contacts the first stop surface 1041, and the first stop surface 1041 limits the stop part 250, ensuring that the stop part 250 cannot continue to move counterclockwise relative to the fixed shell assembly 100, thereby ensuring that the roller 610 cannot continue to roll counterclockwise relative to the fixed shell assembly 100, so that the display screen assembly 200 cannot continue to rotate counterclockwise, so as to avoid the display screen 210 from tilting in landscape mode and affecting the user's visual experience.

[0125] During the process of switching the display screen 210 from landscape mode to portrait mode, the scroll wheel 610 gradually moves away from the first limiting groove 1031. When the scroll wheel 610 is completely away from the first limiting groove 1031, the first elastic element 620 is in its maximum compressed state. When an external force is continued to be applied, causing the display screen assembly 200 to rotate clockwise, the scroll wheel 610 begins to roll along the scroll wheel track groove 102 until the scroll wheel 610 is engaged with the second limiting groove 1032. At this point, the first elastic element 620 is in its minimum compressed state, and the display screen 210 switches to the portrait mode.

[0126] like Figure 4 As shown, when the display screen 210 is in portrait mode, under the action of the first elastic member 620 (or under the combined action of the first elastic member 620 and the gravity of the roller 610), the roller 610 is limited by the second limiting groove 1032. At this time, the stop part 250 contacts the second stop surface 1042, and the second stop surface 1042 limits the stop part 250 so that the stop part 250 cannot continue to move clockwise relative to the fixed shell assembly 100, thereby ensuring that the roller 610 cannot continue to roll clockwise relative to the fixed shell assembly 100, so that the display screen assembly 200 cannot continue to rotate clockwise, so as to avoid the display screen 210 from tilting in portrait mode and affecting the user's visual experience.

[0127] During the process of switching the display screen 210 from portrait mode to landscape mode, the scroll wheel 610 gradually moves away from the second limiting groove 1032. When the scroll wheel 610 is completely away from the second limiting groove 1032, the first elastic member 620 is in its maximum compression state. When the external force is continued to be applied, causing the display screen assembly 200 to rotate counterclockwise, the scroll wheel 610 begins to roll along the scroll wheel track groove 102 until the scroll wheel 610 is in a limiting engagement with the first limiting groove 1031. At this time, the first elastic member 620 is in its minimum compression state, and the stop part 250 contacts the first stop surface 1041. At this time, the display screen 210 switches to the landscape mode.
