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:

[0006] Fixed shell assembly;

[0007] The display assembly is rotatably connected to the fixed housing assembly;

[0008] The stop assembly includes a crank, a slider, a first fixing member, and a second fixing member. The first end of the crank is rotatably connected to the slider. The slider, the first fixing member, and the second fixing member are all disposed in one of the fixed housing assembly and the display screen assembly, and the slider can slide between the first fixing member and the second fixing member. The second end of the crank is rotatably connected to the other of the fixed housing assembly and the display screen assembly.

[0009] When the display assembly is rotated to a first angle, the slider is connected to the first fixing member to lock the display assembly at the first angle; when the display assembly is rotated to a second angle, the slider is connected to the second fixing member to lock the display assembly at the second angle.

[0010] In this embodiment, the crank and the slider work together to accommodate the relative rotation of the display assembly and the fixed housing assembly. During the rotation of the display assembly relative to the fixed housing assembly, the slider slides with the display assembly. Through the connection and cooperation of the slider with the first fixed member and the second fixed member, the rotation of the display assembly can be effectively restricted, locking the display assembly at the required angle. This prevents the display assembly from rotating randomly due to gravity or collision during use, thereby ensuring the stability of the entire rotating screen device during use and ensuring that the user can use the rotating screen device normally.

[0011] Furthermore, during the rotation of the display assembly from one angle to another, such as from the first angle to the second angle, the slider and the first fixing member automatically separate as the display assembly rotates. Until the display assembly reaches the second angle, the slider and the second fixing member connect, automatically locking the display assembly at the second angle. This eliminates the need for additional unlocking operations when rotating the display assembly, making operation simple and convenient, and effectively improving the usability of the rotating screen device.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] refer to Figures 1-15 The rotating screen device provided in this application embodiment may include a fixed housing assembly 100 and a display screen assembly 200. The display screen assembly 200 may be rotatably connected to the fixed housing assembly 100, so that when using the rotating screen device, the user can adjust the position of the display screen assembly 200 according to actual needs.

[0044] The rotating screen device may further include a stop assembly 300, which may include a crank 310, a slider 320, a first fixing member 330, and a second fixing member 340. The first end of the crank 310 is rotatably connected to the slider 320. The slider 320, the first fixing member 330, and the second fixing member 340 may all be disposed on one of the fixed housing assembly 100 and the display screen assembly 200, and the slider 320 may slide between the first fixing member 330 and the second fixing member 340. The second end of the crank 310 is rotatably connected to the other of the fixed housing assembly 100 and the display screen assembly 200. Thus, when the display screen assembly 200 rotates relative to the fixed housing assembly 100, the crank 310 can drive the slider 320 to slide between the first fixing member 330 and the second fixing member 340. Optionally, the slider 320, the first fixing member 330, and the second fixing member 340 can all be disposed on the fixed housing assembly 100, and the second end of the crank 310 can be rotatably connected to the display screen assembly 200. Alternatively, the slider 320, the first fixing member 330, and the second fixing member 340 can all be disposed on the display screen assembly 200, and the second end of the crank 310 can be rotatably connected to the fixed housing assembly 100.

[0045] Specifically, when the display assembly 200 rotates to the first angle, the slider 320 connects to the first fixing member 330 to lock the display assembly 200 at the first angle, forming a mechanical lock between the display assembly 200 and the fixing housing assembly 100, thus restricting the display assembly 200 from continuing to rotate; when the display assembly 200 rotates to the second angle, the slider 320 connects to the second fixing member 340 to lock the display assembly 200 at the second angle, forming a mechanical lock between the display assembly 200 and the fixing housing assembly 100, thus restricting the display assembly 200 from continuing to rotate.

[0046] In this embodiment, the crank 310 and the slider 320 work together to accommodate the relative rotation of the display assembly 200 and the fixed housing assembly 100. During the rotation of the display assembly 200 relative to the fixed housing assembly 100, the slider 320 slides with the display assembly 200. Through the connection and cooperation of the slider 320 with the first fixed member 330 and the second fixed member 340, the rotation of the display assembly 200 can be effectively restricted, locking the display assembly 200 at the required angle. This prevents the display assembly 200 from rotating randomly due to gravity or collision during use, thereby ensuring the stability of the entire rotating screen device during use and ensuring that the user can use the rotating screen device normally.

[0047] Furthermore, during the rotation of the display assembly 200 from one angle to another, such as from the first angle to the second angle, the slider 320 and the first fixing member 330 automatically separate as the display assembly 200 rotates. Until the display assembly 200 reaches the second angle, the slider 320 connects with the second fixing member 340, automatically locking the display assembly 200 at the second angle. This eliminates the need for additional unlocking operations when rotating the display assembly 200, making operation simple and convenient, and effectively improving the usability of the rotating screen device.

[0048] In optional embodiments, such as Figure 7 and Figure 8 As shown, a limiting post 326 can be provided on the sliding member 320. The first end of the crank 310 can be sleeved on the limiting post 326. Furthermore, to prevent the crank 310 from separating from the limiting post 326, a first crank limiting cover 327 can be provided on the limiting post 326. The first crank limiting cover 327 is axially positioned with the first end of the crank 310. Optionally, the diameter of the first crank limiting cover 327 can be larger than the inner diameter of the first end of the crank 310. Here, the first crank limiting cover 327 can be connected to the limiting post 326 by a first screw 328.

[0049] In an optional embodiment of this application, when the display assembly 200 is rotated to a first angle, the slider 320 is magnetically connected or engaged with the first fixing member 330; when the display assembly 200 is rotated to a second angle, the slider 320 is magnetically connected or engaged with the second fixing member 340. In this embodiment, since the slider 320 is magnetically connected or engaged with the first fixing member 330 or the second fixing member 340, when the user rotates the display assembly 200, the slider 320 can automatically disengage from the first fixing member 330 or the second fixing member 340 under the linkage of the crank 310, without the need for additional unlocking operations, making the operation simple and convenient.

[0050] In this embodiment, when the slider 320 is magnetically connected to the first fixing member 330 or the second fixing member 340, when the display assembly 200 approaches the locking angle, the magnetic attraction between the slider 320 and the first fixing member 330 or the second fixing member 340 will automatically pull the slider 320 into place without the user applying additional force. When rotating the display assembly 200, the external force only needs to overcome the magnetic force to disengage the slider 320, and there is no sense of jamming during the rotation. At the same time, when the slider 320 is attracted to the first fixing member 330 or the second fixing member 340, there will be no rigid collision, which can buffer the rotational impact of the display assembly 200, thereby protecting the display assembly 200 and the fixing shell assembly 100.

[0051] When the slider 320 engages with the first fixing member 330 or the second fixing member 340, a clear engagement sound, such as a crisp "click," is produced, along with noticeable tactile feedback, allowing the user to confirm the locking status through hearing and touch, reducing operational errors. Optionally, the first fixing member 330 may be provided with a first elastic claw, the second fixing member 340 may be provided with a second elastic claw, and the slider 320 may be provided with a first spherical protrusion and a second spherical protrusion. When the display assembly 200 is rotated to a first angle, the first spherical protrusion engages with the first elastic claw; when the display assembly 200 is rotated to a second angle, the second spherical protrusion engages with the second elastic claw.

[0052] In optional embodiments, such as Figure 7 and Figure 8 As shown, the side of the slider 320 facing the first fixing member 330 may be provided with a first connecting member 321, and the side of the slider 320 facing the second fixing member 340 may be provided with a second connecting member 322.

[0053] When the display assembly 200 is rotated to the first angle, the slider 320 is magnetically connected to the first fixing member 330 through the first connector 321. When the display assembly 200 is rotated to the second angle, the slider 320 is magnetically connected to the second fixing member 340 through the second connector 322.

[0054] Among them, at least one of the first fixing member 330 and the first connecting member 321 is a magnetic member, and at least one of the second fixing member 340 and the second connecting member 322 is a magnetic member.

[0055] In this embodiment, a first connector 321 and a second connector 322 are provided on the slider 320 to magnetically engage with the first fixing member 330 and the second fixing member 340, respectively. Compared with directly setting the slider 320 as a magnetic structure, on the one hand, it can prevent the slider 320 from forming a magnetic connection with the display assembly 200 or other structures of the fixing housing assembly 100, thus preventing the slider 320 from sliding. On the other hand, if the first connector 321 and the second connector 322 are damaged or their magnetism is weakened, only the first connector 321 and the second connector 322 need to be replaced, without having to replace the entire slider 320.

[0056] In other embodiments, the first connector 321 and the second connector 322 may not be provided on the slider 320, and the slider 320 may be a magnetic structure.

[0057] Optionally, the first fixing member 330 can be a magnetic member, the first connecting member 321 can be made of iron, the second fixing member 340 can be a magnetic member, and the second connecting member 322 can be made of iron. Alternatively, the first fixing member 330 can be made of iron, the first connecting member 321 can be a magnetic member, the second fixing member 340 can be made of iron, and the second connecting member 322 can be a magnetic member. Alternatively, both the first fixing member 330 and the first connecting member 321 can be magnetic members, and the polarities of the ends of the first fixing member 330 and the first connecting member 321 that are close to each other are opposite. Both the second fixing member 340 and the second connecting member 322 can be magnetic members, and the polarities of the ends of the second fixing member 340 and the second connecting member 322 that are close to each other are opposite. For example, the end of the first fastener 330 facing the first connector 321 is the S pole, the end of the first connector 321 facing the first fastener 330 is the N pole, the end of the second fastener 340 facing the second connector 322 is the S pole, and the end of the second connector 322 facing the second fastener 340 is the N pole.

[0058] In some embodiments, the first connector 321 and the second connector 322 can be an integral structure. For example, the first connector 321 and the second connector 322 can be two parts of a magnet. In this case, the end of the first fixing member 330 facing the sliding member 320 can be the S pole, and the end of the magnet facing the first fixing member 330 can be the N pole. Similarly, the end of the second fixing member 340 facing the sliding member 320 can be the N pole, and the end of the magnet facing the second fixing member 340 can be the S pole. This arrangement helps to reduce the number of magnetic components.

[0059] Optionally, such as Figure 7 and Figure 8 As shown, a mounting portion 329 may be provided on the sliding member 320. The mounting portion 329 may be provided with a first mounting groove 3291 and a second mounting groove 3292. The first mounting groove 3291 and the second mounting groove 3292 are arranged opposite to each other, and the openings of the first mounting groove 3291 and the second mounting groove 3292 face opposite directions. The opening of the first mounting groove 3291 may face the first fixing member 330, and the opening of the second mounting groove 3292 may face the second fixing member 340. The first connecting member 321 may be disposed in the first mounting groove 3291, and the second connecting member 322 may be disposed in the second mounting groove 3292. This arrangement facilitates the installation of the first connecting member 321 and the second connecting member 322.

[0060] In optional embodiments, such as Figure 6As shown, the rotating screen device may further include a first circuit board 400, a first trigger 500, and a second trigger 600. The first circuit board 400 is electrically connected to the display screen assembly 200 and may be disposed within the fixed housing assembly 100. The first trigger 500 and the second trigger 600 are both electrically connected to the first circuit board 400 and may be disposed on either the first circuit board 400 or the display screen assembly 200. Optionally, as... Figure 14 As shown, the first trigger 500 and the second trigger 600 are both disposed on the first circuit board 400. This arrangement eliminates the need to electrically connect the first trigger 500 and the second trigger 600 to the first circuit board 400 via wires, thereby simplifying the structure and reducing the overall space occupied by the first circuit board 400, the first trigger 500, and the second trigger 600.

[0061] Optionally, the first trigger 500 and the second trigger 600 can be micro switches. Of course, the first trigger 500 and the second trigger 600 can also be proximity switches or limit switches, or other electrical components capable of signal triggering.

[0062] When the display assembly 200 is rotated to the first angle, the slider 320 triggers the first trigger 500, so that the first circuit board 400 sends a first signal to the display assembly 200, so that the image displayed on the display assembly 200 adapts to the first angle. For example, when the first angle is 90°, that is, when the display assembly 200 is rotated to the landscape state, the first circuit board 400 sends a signal to the display assembly 200 to switch to the landscape state, so that the image on the display assembly 200 switches to the landscape state.

[0063] When the display assembly 200 is rotated to the second angle, the slider 320 triggers the second trigger 600, so that the first circuit board 400 sends a second signal to the display assembly 200, so that the image displayed on the display assembly 200 adapts to the second angle. For example, when the second angle is 0°, that is, when the display assembly 200 is rotated to the portrait state, the first circuit board 400 sends a signal to the display assembly 200 to switch to the portrait state, so that the image on the display assembly 200 switches to the portrait state.

[0064] With this configuration, the screen display of the display assembly 200 automatically adapts to its angle by triggering the first trigger 500 and the second trigger 600 via the slider 320. The screen display only switches when the slider 320 triggers either the first trigger 500 or the second trigger 600, ensuring complete synchronization between screen switching and the position of the display assembly 200. Furthermore, achieving synchronized screen switching solely through mechanical triggering of the slider 320 and either the first trigger 500 or the second trigger 600 is simpler and less costly than relying on attitude sensors and algorithms to identify the state of the display assembly 200.

[0065] In other embodiments, the rotating screen device may not include the first trigger 500 and the second trigger 600. For example, the rotating screen device may include an attitude sensor, which is electrically connected to the first circuit board 400. The attitude sensor detects the attitude of the display assembly 200, and the first circuit board 400 controls the screen of the display assembly 200 according to the detection signal of the attitude sensor.

[0066] Optionally, such as Figure 7 and Figure 8 As shown, the side of the slider 320 facing the first trigger 500 may be provided with a first trigger rib 323, and the side of the slider 320 facing the second trigger 600 may be provided with a second trigger rib 324. When the display assembly 200 rotates to a first angle, the first trigger rib 323 triggers the first trigger 500; when the display assembly 200 rotates to a second angle, the second trigger rib 324 triggers the second trigger 600. In this embodiment, the provision of the first trigger rib 323 and the second trigger rib 324 enhances the reliability and accuracy of the slider 320 triggering the first trigger 500 or the second trigger 600, reduces the possibility of trigger failure due to positional deviation of the slider 320, and ensures that the first circuit board 400 can send corresponding signals to the display assembly 200 in a timely and accurate manner to achieve adaptive switching of the screen.

[0067] Of course, the first trigger rib 323 and the second trigger rib 324 may not be provided on the slider 320.

[0068] like Figure 8 As shown, the first trigger rib 323 and the first connecting member 321 can be respectively disposed close to both ends of the sliding member 320 in the first direction, such as... Figure 7As shown, the second trigger rib 324 and the second connecting member 322 can be respectively positioned close to both ends of the slider 320 in the first direction. Here, the first direction is perpendicular to the rotation axis of the display assembly 200 and perpendicular to the movement direction of the slider 320. This arrangement can fully utilize the space of the slider 320 in the direction perpendicular to the rotation axis of the display assembly 200 and the movement direction of the slider 320, and makes the positions of each component on the slider 320 relatively independent and clear, preventing spatial interference between components and making the structure of the slider 320 more compact and reasonable.

[0069] Of course, the first trigger rib 323 and the first connector 321 may not be located close to the two ends of the slider 320 in the first direction. For example, the first trigger rib 323 and the first connector 321 may be distributed along the direction from the fixed housing assembly 100 to the display assembly 200. The second trigger rib 324 and the second connector 322 may not be located close to the two ends of the slider 320 in the first direction. For example, the second trigger rib 324 and the second connector 322 may be distributed along the direction from the fixed housing assembly 100 to the display assembly 200.

[0070] In an optional embodiment, in the moving direction of the slider 320, the orthographic projection of the first fixing member 330 coincides with the orthographic projection of the first connecting member 321, and the orthographic projection of the second fixing member 340 coincides with the orthographic projection of the second connecting member 322. This configuration ensures that during the movement of the slider 320, the first connecting member 321 is precisely aligned with the first fixing member 330, and the second connecting member 322 is precisely aligned with the second fixing member 340, avoiding magnetic attraction failure or incomplete engagement due to misalignment. Simultaneously, it also ensures that the positions of the first trigger rib 323 and the first trigger member 500, and the second trigger rib 324 and the second trigger member 600, correspond, preventing signal triggering delays or failures due to structural misalignment.

[0071] In other embodiments, the orthographic projection of the first fixing member 330 and the orthographic projection of the first connecting member 321 may not coincide, and the orthographic projection of the second fixing member 340 and the orthographic projection of the second connecting member 322 may not coincide.

[0072] In optional embodiments, such as Figure 9 and Figure 10As shown, the fixed housing assembly 100 may be provided with a first bracket 121 and a second bracket 122. A first fixing member 330 may be disposed in the first bracket 121, and a second fixing member 340 may be disposed in the second bracket 122. Specifically, the first bracket 121 may be provided with a first fixing groove 1211, and the second bracket 122 may be provided with a second fixing groove 1221. The first fixing member 330 may be disposed in the first fixing groove 1211, and the second fixing member 340 may be disposed in the second fixing groove 1221. This arrangement, compared to the method of setting the first fixing member 330 and the second fixing member 340 on the first circuit board 400, can prevent the impact force of the sliding member 320 on the first fixing member 330 and the second fixing member 340 from being transmitted to the circuit board, thereby preventing the circuit board from being deformed by force, and improving the stability of the fixing of the first fixing member 330 and the second fixing member 340.

[0073] The first fixing groove 1211 and the first mounting groove 3291 are at the same height in the direction of the rotation axis of the display assembly 200, and the second fixing groove 1221 and the second mounting groove 3292 are at the same height in the direction of the rotation axis of the display assembly 200. This makes the first fixing member 330 and the first connecting member 321 at the same height in the direction of the rotation axis of the display assembly 200, and the second fixing member 340 and the second connecting member 322 at the same height in the direction of the rotation axis of the display assembly 200. This improves the overlap between the orthographic projection of the first fixing member 330 and the orthographic projection of the first connecting member 321, as well as the overlap between the orthographic projection of the second fixing member 340 and the orthographic projection of the second connecting member 322.

[0074] Optionally, the first circuit board 400 may be provided with a first clearance hole 420 and a second clearance hole 430. The first clearance hole 420 allows the first bracket 121 to pass through in order to avoid the first bracket 121, and the second clearance hole 430 allows the second bracket 122 to pass through in order to avoid the second bracket 122.

[0075] In an optional embodiment, the fixed housing assembly 100 may be provided with a receiving space, the first circuit board 400 may be disposed within the receiving space, the stop assembly 300 may be located within the receiving space, and the slider 320 may be slidably connected to the fixed housing assembly 100. This arrangement avoids exposing the stop assembly 300, which on the one hand improves the aesthetics of the rotating screen device, and on the other hand, effectively utilizes the space of the fixed housing assembly 100, making the layout of each component more compact, thereby helping to reduce the size of the rotating screen device.

[0076] Of course, the stop component 300 may not be located within the receiving space. For example, the stop component 300 may be located between the fixed housing component 100 and the display component 200.

[0077] In an optional embodiment, the display assembly 200 may include a rotatable connecting portion 250 and a crank connecting portion 260. The rotatable connecting portion 250 is rotatably connected to the fixed housing assembly 100. The rotatable connecting portion 250 may be provided with a through hole 251 communicating with the receiving space. The through hole 251 can be used for a connecting wire 800 electrically connected to the first circuit board 400 to pass through. A first part of the crank connecting portion 260 is located in the through hole 251 and connected to the hole wall of the through hole 251. A second part of the crank connecting portion 260 is located in the receiving space. A second end of the crank 310 is rotatably connected to the second part, and the second end of the crank 310 is limitedly engaged with the crank connecting portion 260 in the axial direction. In this embodiment, the crank connecting portion 260 is disposed in the through hole 251, which can effectively utilize the space of the through hole 251, thereby improving space utilization. Here, the crank connecting portion 260 can be a cylindrical structure.

[0078] In other embodiments, the display assembly 200 may also not include the crank connection portion 260. For example, the second end of the crank 310 may be rotatably connected to the rotating connection portion 250 of the display assembly 200 or to other positions of the display assembly 200.

[0079] Optionally, the second end of the crank 310 can be sleeved outside the second part of the crank connecting portion 260. To prevent the crank 310 from separating from the second part of the crank connecting portion 260, a second crank limiting cover 261 can be provided on the second part of the crank connecting portion 260. The second crank limiting cover 261 and the second end of the crank are locked together axially in the crank connecting portion 260. For example, the diameter of the second crank limiting cover 261 can be larger than the inner diameter of the second end of the crank 310. Here, the second crank limiting cover 261 can be connected to the crank connecting portion 260 by a second screw 262. In this embodiment, through the limiting effect of the second crank limiting cover 261 and the crank connecting portion 260, it can be ensured that the crank 310 can only rotate relative to the crank connecting portion 260 and cannot move axially or radially relative to the crank connecting portion 260.

[0080] In an optional embodiment, where the second end of the crank 310 is rotatably connected to the display assembly 200, one of the fixed housing assembly 100 and the slider 320 is provided with a groove 325 and the other is provided with a rail 111.

[0081] When the second end of the crank 310 is connected to the fixed housing assembly 100, one of the display assembly 200 and the slider 320 is provided with a groove 325 and the other is provided with a rail 111.

[0082] The slide rail 111 is slidably connected to the slide groove 325, and the groove wall of the slide groove 325 is in a limiting fit with the slide rail 111 in the direction of the rotation axis of the display assembly 200. This arrangement can prevent the sliding member 320 from separating from the fixed shell assembly 100 or the display assembly 200.

[0083] In this embodiment, the slider 320 may be provided with a groove 325, such as Figure 11 and Figure 12 As shown, a slide rail 111 may be provided on the fixed shell assembly 100. Specifically, the slide rail 111 is provided on the middle frame 110 described below.

[0084] Of course, in the direction of the rotation axis of the display assembly 200, the groove wall of the slide 325 and the slide rail 111 can also be matched without being limited.

[0085] Optionally, both the slide groove 325 and the slide rail 111 can be T-shaped structures.

[0086] In optional embodiments, such as Figure 13 As shown, a limiting part 113 is provided on the slide rail 111. The limiting part 113 is located at one end of the slide rail 111 near the rotation axis of the display assembly 200. In the direction from the slide rail 111 to the rotation axis of the display assembly 200, the first sidewall 3210 of the slide groove 325 is limited and engaged with the limiting part 113. The first sidewall 3210 is the sidewall of the slide groove 325 in the moving direction of the slider 320. This arrangement can prevent the slide rail 111 from sliding out of the slide groove 325 during the engagement of the slide groove 325, especially during the assembly process, thus preventing the slide rail 111 from sliding out of the slide groove 325 and preventing the slider 320 from separating from the fixed housing assembly 100. Optionally, two limiting parts 113 may be provided on the slide rail 111. The two limiting parts 113 are respectively provided close to the two sides of the slide rail 111 to ensure that the first side wall 3210 of the slide groove 325 is in force balance when it contacts the limiting part 113, thereby ensuring that the sliding member 320 is in force balance.

[0087] Of course, the limit part 113 may not be provided on the slide rail 111.

[0088] In an optional embodiment, the fixed housing assembly 100 may include a bottom housing 120 and a middle frame 110 connected to the bottom housing 120. A receiving space may be formed between the middle frame 110 and the bottom housing 120. A slide rail 111 may be provided on the side of the middle frame 110 facing the bottom housing 120. The display assembly 200 may include a display screen 210, a screen fixing bracket 220, and a screen rear housing 230. The screen fixing bracket 220 is provided with a mounting groove for mounting the display assembly 200. The screen rear housing 230 is connected to the side of the screen fixing bracket 220 away from the display screen 210. The aforementioned rotating connecting part 250 is provided on the screen rear housing 230. A rotating fixing part 112 may be provided on the middle frame 110. The rotating fixing part 112 and the rotating connecting part 250 may be connected by a bearing 700. Specifically, the rotating fixing part 112 may be connected to the outer ring of the bearing 700, and the rotating connecting part 250 may be connected to the inner ring of the bearing 700.

[0089] Optionally, the display assembly 200 may further include a second circuit board 240, which may be disposed within the screen mounting bracket 220. A first socket 410 may be disposed on the first circuit board 400, and a second socket 241 may be disposed on the second circuit board 240. The two ends of the connecting wire 800 may be electrically connected to the first socket 410 and the second socket 241 respectively, and the display 210 may be electrically connected to the terminal block on the second circuit board 240 via a wire, thereby realizing the signal connection between the display 210, the second circuit board 240 and the first circuit board 400.

[0090] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, when the display assembly 200 is in landscape mode, i.e., at 90°, visually, the second top side 2201 of the screen fixing bracket 220 and the first top side 1101 of the middle frame 110 are on the same side. Internally, the first side wall 3210 of the slide groove 325 contacts the limiting part 113, and the sliding member 320 remains stable under the magnetic attraction of the first connecting member 321 and the first fixing member 330, preventing the display assembly 200 from tilting to the left or right in landscape mode and affecting the user's visual experience. At the same time, the first trigger rib 323 presses the first trigger member 500 to ensure that the circuit signal state of the first circuit board 400 is in landscape mode. The signal is transmitted to the display 210 through the first socket 410, connecting line 800, second socket 241, and terminal block, so that the screen of the display 210 is in landscape mode.

[0091] When the screen mounting bracket 220 is turned clockwise by an external force, causing the display screen 210 to rotate, the components fixed to the screen mounting bracket 220 will rotate clockwise around the axis of the bearing 700. At this time, the crank connecting part 260 will drive the crank 310 to rotate, thereby causing the first end of the crank 310 to push the slider 320 to slide along the slide rail 111 to the outside of the middle frame 110. At the same time, the external force needs to gradually overcome the magnetic attraction between the first connecting part 321 and the first fixing part 330 until the first trigger rib 323 separates from the first trigger 500. Applying external force causes the display assembly 200 to continue rotating clockwise, causing the second connector 322 and the second fixing member 340 to magnetically attract each other until the first mounting groove 3291 contacts the end of the first fixing groove 1211. The sliding member 320 stops sliding, and the second trigger rib 324 triggers the second trigger member 600, transmitting a signal to the display 210 through the first socket 410, connecting line 800, second socket 241, second circuit board 240, and terminal block, causing the display screen 210 to switch to portrait mode.

[0092] like Figure 3 and Figure 4 As shown, when the display assembly 200 is in portrait mode, i.e., at 0°, visually, the second top side 2201 of the screen fixing bracket 220 and the first right side 1102 of the middle frame 110 are on the same side. Internally, the slider 320 remains stable under the magnetic attraction of the second connector 322 and the second fixing member 340, preventing left or right tilting in portrait mode that would affect the user's visual experience. Simultaneously, the second trigger rib 324 presses the second trigger member 600, ensuring that the circuit signal state of the first circuit board 400 is in portrait mode.

[0093] When the screen mounting bracket 220 is turned counterclockwise by an external force to rotate the display screen 210, the components fixed to the screen mounting bracket 220 will rotate counterclockwise around the axis of the bearing 700. At this time, the crank connecting part 260 will drive the crank 310 to rotate, and then push the slider 320 along the slide rail 111 to slide inward to the middle frame 110 through the first end of the crank 310. At the same time, the external force needs to gradually overcome the adsorption force between the second connecting part 322 and the second fixing part 340 until the second trigger rib 324 separates from the second trigger 600. Applying external force causes the display assembly 200 to continue rotating counterclockwise, causing the first connector 321 to magnetically attract the first fixing member 330 until the ends of the first mounting groove 3291 and the first fixing groove 1211 come into contact. The sliding member 320 stops sliding, and at this time the first trigger rib 323 comes into contact with the first trigger member 500. The circuit signal of the first circuit board 400 switches to the landscape mode and transmits the signal to the display 210 through the first socket 410, the connecting line 800, the second socket 241, the second circuit board 240, and the terminal block, so that the screen of the display 210 switches to the landscape mode.
