Rotary screen structure and sound box

Abstract

The application provides a rotating screen structure and a sound box. The rotating screen structure is arranged on a shell and comprises a support capable of rotating relative to the shell between a folded position and an unfolded position; a display rotatably connected to the support; and a first driving device for driving the display to rotate about an axis of a second rotary connection. The first driving device is integrally arranged on the support, so that a transmission path between the display and the first driving device is always constant and is not affected by the rotation of the support. When the support is in the unfolded position, the display can rotate at least 180 degrees about the axis of the second rotary connection by the driving of the first driving device, independently of the rotation of the support, so that a user can face the display at different positions. The problem that the screen of the sound box deviates from the line of sight and cannot be turned to affect the operation convenience and immersive experience is solved.

Description

Technical Field

[0001] This application relates to the field of speaker structure technology, and more particularly to a rotating screen structure and speaker. Background Technology

[0002] Some existing speakers have integrated an openable screen on top. When unfolded, the screen forms a 90° vertical angle with the top surface of the speaker, allowing users to control functions such as song selection and music video playback via touch.

[0003] Currently, speaker screens typically only flip open by rotating around a horizontal axis, or unfold using a stand that rotates around a horizontal axis. Once unfolded, the screen's left and right angles cannot be adjusted; the screen can only face one position in the left and right directions. For example, patent CN222691836U, entitled "A Portable Folding Video Speaker," discloses a technical solution where the screen flips and folds up and down for storage. When the user is not directly facing the speaker screen in the left or right direction, they need to actively adjust their position or readjust the speaker's angle to face the screen for optimal viewing. Furthermore, when the user moves (e.g., gets up, changes seats), the screen content may shift out of their line of sight, affecting ease of operation and the immersive experience.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a rotating screen structure and speaker, which solves the problem that the speaker screen cannot be turned when it is out of the line of sight, thus affecting the ease of operation and immersive experience.

[0006] This application provides a rotating screen structure for mounting on a housing. The rotating screen structure includes a support member rotatably connected to the housing via a first rotating connection portion, such that the support member can rotate relative to the housing between a folded position and an unfolded position. The display is rotatably connected to the support member via a second rotating connection, the axis of which is perpendicular to the axis of the first rotating connection. The first driving device is disposed on the support member and is connected to the display in a transmission manner, and is used to drive the display to rotate around the axis of the second rotating connection part. In this way, by mounting the first driving device entirely on the support member, the transmission path between the display and the first driving device remains constant and is not affected by the rotation of the support member. When the support is in the open position, the display can rotate at least 180 degrees around the axis of the second rotating connection part independently of the rotation of the support, driven by the first driving device, so that the user can face the display from different positions.

[0007] Optionally, the first driving device includes: First drive motor; The transmission mechanism is connected between the output shaft of the first drive motor and the display.

[0008] Optionally, the transmission mechanism is a constant transmission ratio transmission mechanism.

[0009] Optionally, the constant transmission ratio transmission mechanism is a gear transmission mechanism, including a first gear and a second gear that mesh with each other. The first gear is connected to the output shaft of the first drive motor, and the second gear is connected to the second rotating connection part of the display.

[0010] Optionally, the rotating screen structure also includes a first rotation limiting mechanism for limiting the rotation angle of the second rotating connection and the display. The first rotational limiting mechanism includes: a limiting stop, disposed on the support member; A first limiting arc groove is formed circumferentially on the second rotating connection part; The limiting stop extends into the first limiting arc groove and, through the two ends of the first limiting arc groove, limits the rotational limit position of the second rotating connection.

[0011] Optionally, the first rotating connection includes a damping shaft assembly, and the support is rotatably connected to the housing via the damping shaft assembly.

[0012] Optionally, the damping shaft assembly includes: Fixed end, fixed to the housing; The stud end penetrates the support component; The damping plate assembly is sleeved on the stud end and located between the support and the fixed end; Tighten the lock nut, screw it onto the stud end, and press the damping plate assembly into place.

[0013] Optionally, a second rotation limiting mechanism is also provided on the first rotating connection part to limit the rotation range of the support member relative to the housing; The second rotation limiting mechanism includes a second limiting arc groove formed on the housing and a second limiting stop disposed on the support member and extending into the second limiting arc groove; The two ends of the second limiting arc groove constitute a limit to the extreme position of the rotation of the support.

[0014] Optionally, it also includes a second drive unit, disposed in the housing and connected to the support member for driving the support member and the display mounted thereon to rotate automatically relative to the housing.

[0015] On the other hand, this application also proposes a rotating screen structure for mounting on a housing, the rotating screen structure comprising: The support member is rotatably connected to the housing via a first rotating connection, so that the support member can rotate relative to the housing between a retracted position and an open position. The display is rotatably connected to the support member via a second rotating connection, the axis of which is perpendicular to the axis of the first rotating connection. The second rotating connection is configured to allow the display to be manually rotated at least 180 degrees around its axis and to stop at any angle, so that the user can manually adjust and face the display from different positions.

[0016] Thirdly, this application also proposes a speaker, including a speaker body and a rotating screen structure as described above, wherein the rotating screen structure is disposed on the casing of the speaker body.

[0017] Optionally, the speaker body also includes a control module, which is configured to: detect whether the support is in the open position, and automatically turn on the display in response to detecting that the support is in the open position.

[0018] Beneficial Effects: The rotating screen structure and speaker of this application connect a support member to the casing via a first rotating connection, allowing the support member to rotate around the axis of the first rotating connection. Flipping the support member allows the monitor to rotate between a retracted position and an open position. In the retracted position, the monitor is covered by the casing for storage. In the open position, the monitor is exposed and faces forward. When the user moves (e.g., gets up, changes seats), and the screen moves out of the user's line of sight, a first driving device can be used to drive the monitor to rotate around the axis of a second rotating connection. The monitor rotates clockwise or counterclockwise in the horizontal direction, bringing the screen back into the user's line of sight for easier viewing of the displayed content. The monitor's adjustment is more flexible due to at least two degrees of rotational freedom, making the speaker suitable for more entertainment environments and providing users with a better audio-visual experience.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer and more explicit, the following detailed description of this application is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0022] like Figure 1 , Figure 2As shown, this embodiment proposes a rotating screen structure for mounting on the casing 11 of the speaker body 10. The speaker body 10 can be a smart speaker used to provide audio and video playback. For ease of structural description, the speaker body 10 is placed vertically as an example, with the vertical direction being up and down, the width direction being left and right, the direction facing the user being front, and the direction away from the user being rear. The structure in this embodiment is described with reference to this. The rotating screen structure can be located on the top of the speaker body 10 and can be opened and rotated for video playback.

[0023] like Figure 1 , Figure 2 As shown, the rotating screen structure of this embodiment mainly includes: a support member 200, a first rotating connection part 400, a display 100, a second rotating connection part 330, and a first driving device 300. The support member 200 is rotatably connected to the housing 11 via the first rotating connection part 400, and the display 100 is rotatably mounted on the support member 200 via the second rotating connection part 330. Figure 1 As shown in Figures (a) and (b), the axis of the first rotating connection 400 is horizontal. By flipping the support 200 on the housing 11, the display 100 can be at least partially exposed outside the housing 11. This allows the display 100 to be opened from a folded position to a predetermined open position on the speaker body 10 (e.g., a position where the display 100 and the top plane of the speaker body 10 form a 90° ± 5° angle), enabling the display 100 screen to face forward. The display folds and unfolds by rotating around the axis of the first rotating connection, making the unfolded structure of the display more compact. Figure 2 As shown, the axis of the second rotating connection 330 is vertical. The first driving device 300 is mounted on the support member 200 and is connected to the display 100 via the second rotating connection 330. The first driving device 300 provides power to allow the display 100 to rotate. By mounting the first driving device 300 entirely on the support member, the transmission path between the display and the first driving device remains constant and is unaffected by the rotation of the support member. Figure 1As shown in Figure (3), when the display 100 is in the open position, the first driving device 300 can drive the display 100 to rotate around the axis of the second rotating connection 330. When the speaker is in use, if the user's position changes or the screen of the display 100 is not facing the user, the first driving device 300 can be controlled to drive the display 100 to rotate to the left (clockwise) or right (counterclockwise) around the up and down direction, thereby adjusting the screen of the display 100 in the left and right direction. It can even rotate the screen from facing the front to facing the back, so that the screen of the display 100 can be rotated into the user's line of sight, making it easier for the user to see the display content of the display 100. The display can adjust the angle of the speaker display more flexibly by adjusting at least two degrees of rotational freedom around the axis of the first rotating connection and the axis of the second rotating connection, making it suitable for more entertainment environments and obtaining a better audio and video experience.

[0024] like Figure 2 , Figure 3 As shown, the first driving device 300 further includes a first driving motor 310 and a transmission mechanism 320, with the transmission mechanism 320 connected between the output shaft of the first driving motor 310 and the display 100. The first driving motor 310 can be controlled by the speaker's control system. For example, the control system determines the adjustment angle based on the detected user's location, and then controls the forward and reverse rotation and the number of rotations of the first driving motor 310 based on the adjustment angle. The first driving motor 310 rotates after being powered on, driving the display 100 to rotate via the transmission mechanism 320. Alternatively, the control system can receive a remote control signal from the user (e.g., left or right turn) and start / stop and reverse the direction of rotation accordingly.

[0025] like Figure 2 , Figure 3 As shown, the transmission mechanism 320 is a fixed transmission ratio transmission mechanism. For example, it could be a belt drive mechanism, a chain drive mechanism, or a linkage drive structure. In this embodiment, a gear transmission mechanism 320 with a fixed transmission ratio is used as an example for structural description. It includes a first gear 321 and a second gear 322 that mesh with each other. The first gear 321 is connected to the output shaft of the first drive motor 310, and the second gear 322 is connected to the display 100. Through the engagement of the first gear 321 and the second gear 322, not only is the rotation of the display 100 achieved, but the gear engagement accuracy also ensures a more precise rotational position of the display 100.

[0026] like Figure 2 , Figure 3As shown, the second rotating connection 330 is rotatably mounted on the support 200 and connected to the display 100 in the vertical direction. The second rotating connection 330 can be a rotating connecting shaft. One end of the rotating connecting shaft is connected to the display 100 via a screen mounting bracket 331, and the other end is fixed to a second gear 322. The second rotating connection 330 drives the display 100 to rotate through the engagement of the second gear 322 and the first gear 321. Specifically, when the display 100 is opened to the flip-up position, the display 100 is located above the support 200. The lower end of the second rotating connection 330 passes through the support 200 and is located below it. The first drive motor 310 is fixed below the support 200, and the first gear 321 and the second gear 322 mesh below the support 200. This provides more installation space for the first drive device 300, preventing the first drive device 300 from occupying too much installation space and interfering with the display 100 above the support 200.

[0027] like Figure 2 , Figure 3 As shown, the rotating screen structure also includes a first rotation limiting mechanism 340, used to limit the rotation angle of the second rotating connection 330 and the display 100. The first rotation limiting mechanism 340 specifically includes: a limiting ring 341, a limiting stop 342, and a limiting groove 332. The limiting ring 341 is fixedly mounted on the support member 200 or the housing 11. The second rotating connection 330 passes through the limiting ring 341. The limiting stop 342 is disposed on the limiting ring 341 and protrudes inward. The limiting groove 332 is circumferentially formed in the second rotating connection 330, thus forming a first limiting arc groove. The limiting stop 342 extends into the limiting groove 332 (first limiting arc groove) and achieves rotation limiting by abutting against the circumferential side walls of the limiting groove 332 (first limiting arc groove). In the specific structure, taking the limiting ring 341 being snapped or screwed onto the support member 200 as an example, the limiting stop 342 is integrally formed on the upper surface of the limiting ring 341 and faces the center of the limiting ring 341. The lower outer diameter of the second rotating connecting part 330 is small, allowing it to pass through and rotatably fit into the limiting ring 341. The upper outer diameter of the second rotating connecting part 330 is large, and a limiting groove 332 extending circumferentially is formed on the outer surface of the upper part. The limiting stop 342 is fitted into the limiting groove 332. The space between the two side walls of the limiting groove 332 is the movable space of the limiting stop 342. When the second rotating connecting part 330 rotates, it can only rotate within the limiting groove 332, thus realizing the limiting function.

[0028] like Figure 2 , Figure 3As shown, the support member 200 can further be a support cover 210, with protruding connecting ears 220 on the left and right sides of the rear side of the support cover 210. The protruding connecting ears 220 on the left and right sides can be rotatably connected to the housing 11. The rotation of the support member 200 can be either manual or automatic. The specific structure is as follows: like Figure 4 , Figure 5 As shown, in the first type of manually rotating flip-open structure, the first rotating connection part 400 includes a damping pivot assembly 405, and the support member 200 is rotatably connected to the housing 11 through the damping pivot assembly 405. The protruding connecting ears 220 on both the left and right sides are connected to the damping pivot assembly 405. When the user manually flips the display 100, the damping pivot assembly 405 provides damping during the rotation of the support member 200 relative to the housing 11, allowing the display 100 to remain stably in the flipped position without falling during the up-and-down flipping process.

[0029] like Figure 4 , Figure 5 As shown, the damping shaft assembly 405 specifically includes: a fixed end 411, a stud end 412, a damping plate assembly 420, and a locking nut 430. The fixed end 411 is fixed to the housing 11. The stud end 412 passes through the support member 200. The damping plate assembly 420 is sleeved on the stud end 412 and located between the support member 200 and the fixed end 411. The locking nut 430 is screwed onto the stud end 412 and presses the damping plate assembly 420 tight. In the specific structure, the damping shaft 410 of the damping shaft assembly 405 is arranged in the left-right direction. The fixed end 411 of the damping shaft 410 has a screw hole and is fixed to the housing 11 by screws. The stud end 412 of the damping shaft 410 passes through the protruding connecting ear 220 of the support member 200. The protruding connecting ear 220 is bent into a hook shape or an L shape and has a downwardly protruding mounting ear plate 221. The mounting ear plates 221 on the left and right sides form a mounting position 222 on the opposite side. The mounting position 222 is located inside the mounting ear plate 221. The stud end 412 is located in the mounting position 222. The mounting position 222 can provide sufficient installation space so that the support member 200 can rotate around the damping shaft 410. The damping plate assembly 420 is located in the mounting position 222 and sleeved on the stud end 412, abutting against the inner side of the mounting ear plate 221. It is then screwed onto the stud end 412 by the locking nut 430, pressing the damping plate assembly 420 against the inner side of the mounting ear plate 221 to generate damping for the rotation of the housing 11.

[0030] like Figure 5As shown, a second rotation limiting mechanism 440 is further provided on the first rotating connection portion 400 to limit the rotation range of the support member relative to the housing. The second rotation limiting mechanism 440 includes a second limiting arc groove formed on the housing and a second limiting stop provided on the support member and extending into the second limiting arc groove. The two ends of the second limiting arc groove constitute a limit on the extreme rotation position of the support member.

[0031] In a specific structure, the second rotation limiting mechanism 440 can be disposed on the damping shaft assembly 405 to limit the rotation range of the support member 200 relative to the housing 11. For example, the second rotation limiting mechanism 440 specifically includes a second limiting ring 441 and a second limiting stop 443. The second limiting ring 441 is fixedly disposed on the damping shaft 410 and located on the outer side of the mounting ear plate 221. A second limiting groove 442 is formed in the circumferential direction of the second limiting ring 441, thereby forming a second limiting arc groove. The second limiting stop 443 protrudes from the outer wall of the support member 200 (e.g., the outer wall of the mounting ear plate 221). The second limiting stop 443 is movably disposed within the second limiting groove 442 (second limiting arc groove) and is limited by the inner walls on both sides of the circumferential direction of the second limiting groove 442 (second limiting arc groove).

[0032] like Figure 6 , Figure 7 As shown, in the second type of automatic rotating and opening structure, a second driving device 500 can automatically drive the rotation of the support member 200. The second driving device 500 is disposed on the housing 11 and is connected to the support member 200 for driving the support member 200 and the display 100 disposed thereon to rotate together relative to the housing 11. The second driving device 500 can be independently connected to the housing 11 and drive the support member 200 and the display 100 to rotate together, or it can be combined with the first type of manually rotating structure to drive the support member 200 and the display 100 to rotate together.

[0033] Because the second drive device 500 inside the speaker body automatically drives the support 200 and the display 100 to rotate simultaneously, for example, when the user is using the speaker, they can wake it up via infrared, gesture, or voice, and the display 100 will automatically flip to a position approximately 90 degrees from the top surface of the speaker (e.g., 90°±5°, which is the flipped-up position, and this angle is the flip angle), allowing the user to use the display 100 normally. With the second drive device 500 installed, the user can also manually flip the display 100. If the flip angle deviates from 90°±5°, the display 100 might collide with the speaker body 10 if it follows the user's rotation. Therefore, an angle detection sensor can detect the flip angle of the display 100. When the flip angle is greater than or less than 90°±5°, the second drive device 500 is controlled to drive the support 200 and the display 100 to automatically flip to the appropriate angle, allowing the speaker to smoothly follow the user's rotation angle.

[0034] like Figure 6 , Figure 7 As shown, when used alone, the second drive device 500 is only installed on at least one side of the support member 200 in the left-right direction, specifically including: a second drive motor 510 and a second gear transmission assembly 520. The second drive motor 510 is fixedly installed on the housing 11, and the second gear transmission assembly 520 connects the second drive motor 510 and the support member 200. It should be noted that the second gear transmission assembly 520 can be replaced by a belt drive assembly, a chain drive assembly, etc.

[0035] like Figure 6 , Figure 7 As shown, for example, the second gear transmission group 520 mainly includes: a third gear 521, a fourth gear 522, and a fifth gear 523. The third gear 521 is connected to the shaft of the second drive motor 510, the fourth gear 522 meshes with the third gear 521, and the fifth gear 523 is connected to the support member 200 and meshes with the fourth gear 522. (Reference) Figure 9 In the specific structure, a plug-in boss 223 protrudes from the inner side of the mounting ear plate 221 of the support member 200, and a keyway 524 is formed in the inner hole of the fifth gear 523. When the plug-in boss 223 is inserted into the keyway 524, the fifth gear 523 is connected to the support member 200, thereby realizing the transmission of the support member 200.

[0036] like Figure 7As shown, the fourth gear 522 is rotatably connected to the gear support 530 via a gear shaft 531, and the gear support 530 is fixedly mounted on the housing 11. Bearings 532 are connected to both ends of the gear shaft 531 and are mounted on the gear support 530. Two bearing slots 533 are spaced apart on the gear support 530, and bearing retaining covers 540 are detachably connected to the bearing slots 533. The bearings 532 at both ends are respectively embedded in the two bearing slots 533 and fixed by the bearing retaining covers 540. The bearings 532 mounted on the gear support 530 ensure smooth rotation of the fourth gear 522, and the bearing retaining covers 540 facilitate installation and prevent the bearings 532 from shifting.

[0037] like Figure 8 , Figure 9 As shown, when the second drive device 500 is used in conjunction with the damping shaft assembly 405, after the stud end 412 passes through the mounting ear plate 221 and the fifth gear 523, the stud end 412 is fixed relative to the housing 11. Then, the mounting ear plate 221 and the fifth gear 523 rotate around the central axis of the stud end 412. By fitting the damping plate assembly 420 onto the stud end 412 and positioning it on the side of the fifth gear 523 away from the mounting ear plate 221, and then screwing the locking nut onto the stud end 412 to press the damping plate assembly 420 against the inner side of the fifth gear 523, damping can be applied to the automatic rotation of the support member 200.

[0038] In another embodiment, this application also proposes another rotating screen structure that allows for manual rotation. For example, the rotating screen structure is mounted on a housing and includes a support member and a display. The support member is rotatably connected to the housing via a first rotating connection, allowing the support member to rotate relative to the housing between a folded position and an open position. The display is rotatably connected to the support member via a second rotating connection, the axis of which is perpendicular to the axis of the first rotating connection. The second rotating connection is configured to allow the display to be manually rotated at least 180 degrees around its axis and to stop at any angle, allowing the user to manually adjust and face the display from different positions. Using the above rotating screen structure, the user can manually rotate the left and right angles of the display to achieve manual adjustment of the display's left and right angles.

[0039] During manual adjustment of the display's left and right angles, to ensure the display can stop at any angle, a second damping pivot assembly can be configured at the second rotating connection. This allows the display to be rotatably connected to the support via the second damping pivot assembly. Consequently, after manual rotation, the display can be stably stopped at any angle due to the damping effect of the second damping pivot assembly.

[0040] In some embodiments, this application also proposes a speaker, including a speaker body 10 and a rotating screen structure as described above, the rotating screen structure being disposed on the housing 11 of the speaker body 10. The speaker body 10 can be a smart speaker for providing audio and video playback. For example, an installation space is provided inside the housing 11, the rotating screen structure is disposed in the installation space, and the display 100 of the rotating screen structure is exposed on the top of the housing 11.

[0041] For example, after the user flips the monitor 100 to the open position (about 90°), making the top surface of the monitor 100 perpendicular (approximately perpendicular) to the top surface of the speaker body 10, the camera installed on the monitor 100 uses image recognition technology to identify the user's position, thereby controlling the first drive device 300 to drive the monitor 100 to rotate left and right, automatically adjusting to a suitable angle; when the user's position changes, adaptive angle adjustment is performed.

[0042] The speaker body also includes a control module, and the rotational position of the support member can be detected by a detector. The angle detector can be a Hall sensor, a photoelectric proximity switch, or a contact switch. When the detector detects that the support member is in the open position, it triggers the control module to respond and automatically illuminates the display, which can display a graphical user interface for user convenience.

[0043] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
