Description

Technical Field

[0001] This utility model relates to the field of intelligent audio equipment technology, and in particular to an anti-tipping lift-up screen intelligent speaker. Background Technology

[0002] With the rapid development of smart audio devices, multi-functional speakers with integrated displays are gradually becoming the mainstream in the market. These speakers typically combine audio and video playback, interactive control, and other functions, and are widely used in home entertainment, conference systems, and other scenarios. However, existing speakers with integrated displays still have significant shortcomings in terms of structural design and stability.

[0003] Among them, speakers with screens are prone to tipping over due to their high center of gravity (especially when the screen is raised), causing equipment damage or safety hazards. Existing solutions mostly use external stands or weighted bases, but these designs have obvious drawbacks: external stands require additional installation and take up space, affecting the portability of the device; while weighted bases improve stability, they significantly increase the weight of the device, which contradicts users' demand for lightweight products. Some products attempt to set foldable legs on the side of the speaker, but their unfolding angle and support area are limited, and they rely on manual operation, making it difficult to achieve intelligent adaptation.

[0004] In summary, there is an urgent need for a speaker solution that integrates a height-adjustable display screen, an intelligent anti-tipping structure, and a compact design to address the pain points of existing technologies, such as poor device stability, complex operation, and insufficient adaptability to various scenarios.

[0046] This utility model provides an anti-tipping, lift-up screen smart speaker. Please refer to [reference needed]. Figures 1-8 The smart speaker with a liftable screen includes a speaker body 1, a support member 3, and a control unit. The speaker body 1 has a mounting cavity 11 on its side, and the support member 3 is disposed within the mounting cavity 11. The support member 3 is used to stabilize the speaker body 1 in a predetermined position. The support member 3 includes a drive assembly 31 and a bracket assembly 32. The drive assembly 31 is disposed within the speaker body 1, and the bracket assembly 32 is driven by the drive assembly 31, having a retracted state (folded into the mounting cavity 11) and an extended state (extended from the mounting cavity 11 and in contact with the support surface). The control unit is disposed within the speaker body 1 and is used to control the drive assembly 31 to cause the bracket assembly 32 to extend and retract accordingly. This design utilizes the drive assembly... The linkage design of component 31 and bracket assembly 32 improves anti-tipping performance while taking into account aesthetics and practicality. The bracket assembly 32 can be extended in a controlled manner to contact the support surface, reducing the risk of center of gravity shift. When retracted, it is completely hidden in the mounting cavity 11 on the side of the speaker, ensuring a clean appearance. In addition, combined with intelligent control components, users can switch the bracket state with one click, flexibly adapting to different usage scenarios and support surface materials. The adaptive adjustment improves the grip stability, and the drive component 31 only operates with low noise when extending or retracting, achieving energy-saving goals while avoiding mechanical wear and extending equipment life. This comprehensively optimizes product safety, environmental adaptability, and user experience.

[0047] In this embodiment, please refer to Figure 4 The drive component 31 includes a drive motor to provide a power source to the bracket assembly 32, so that the bracket assembly 32 can extend and retract accordingly. In other embodiments, the drive component 31 can also be other micro motors, as long as they can be controlled by the control components to drive the bracket assembly 32 to perform the corresponding work.

[0048] For further details, please refer to... Figures 1-3The smart speaker with a lift-up screen also includes a lifting device and a display screen 2. The lifting device is mounted on the speaker body 1, and the bottom of the display screen 2 is connected to the lifting device. The lifting device is electrically connected to a control unit so that the drive component 31 moves synchronously with the lifting device. In other words, when the user operates the lifting device to raise or lower the display screen 2, at the same time, the drive component 31, controlled by the control unit, will drive the bracket component 32 to extend or retract accordingly. For example, when the display screen 2 rises, the bracket component 32 will extend out of the mounting cavity 11 and contact the support surface; when the display screen 2 descends, the bracket component 32 will retract and finally be housed in the mounting cavity 11. This allows the display screen 2 and the bracket component 32 to be stored on the speaker body 1 simultaneously. The above settings ensure that the extension and retraction of the bracket component 32 are completed automatically, eliminating the need for the user to bend over and manually operate the bracket component 32 to unfold and retract, thus improving the user experience.

[0049] It should be noted that the lifting device used for the lifting display screen 2 is existing technology, which should be known to those skilled in the art, and will not be described in detail here.

[0050] In this embodiment, please refer to Figure 3 and Figure 4 The bracket assembly 32 includes a bracket housing 321, a first drive shaft 322, and a first bracket 323. The first drive shaft 322 is connected to the output end of a drive motor, and a first thread 3221 is provided on the outside of the first drive shaft 322. The first bracket 323 is threadedly connected to the first drive shaft 322 inside. When the drive motor drives the first drive shaft 322 to rotate, the first bracket 323 located on the first drive shaft 322 will move along the length direction of the first drive shaft 322, so that the first bracket 323 extends out of the mounting cavity 11 and contacts and abuts against the support surface, stabilizing the lifting screen smart speaker in a predetermined position.

[0051] It should be noted that in this embodiment, a connecting plate 3211 is provided on the outside of the bracket housing 321. The connecting plate 3211 is connected to the inside of the speaker body 1 by fastening screws. Secondly, the bracket housing 321 is covered by the first bracket 323, and the first drive shaft 322 is provided in the mounting cavity 11 through the bracket housing 321. The above arrangement is mainly to fix the position of the bracket housing 321, thereby fixing the position of the first drive shaft 322, ensuring that the first bracket 323 can move stably on the first drive shaft 322, and ensuring that other structures connected to the first drive shaft 322 can also operate normally.

[0052] Furthermore, the bracket assembly 32, through the coordinated extension and retraction of multiple bracket segments, can adapt to the changing center of gravity of the height-adjustable speaker, thereby stabilizing the height-adjustable speaker in a predetermined position and preventing the entire height-adjustable speaker from shaking or tipping over when the user operates the display screen 2 at different heights.

[0053] Specifically, in some embodiments, Figure 3 and Figure 4 Following the foregoing, the first drive shaft 322 has a plurality of first grooves 3222 recessed inward along the length direction of the first drive shaft 322. The plurality of first grooves 3222 are arranged around the axis of the first drive shaft 322. The bracket assembly 32 also includes a second drive shaft 324 and a second bracket 325. The second drive shaft 324 has a second thread 3241 on its exterior and a first protrusion 3242 engaged by the first grooves 3222 inside the second drive shaft 324. The second bracket 325 is located inside the first bracket 323 and is threadedly connected to the second drive shaft 324 inside the second bracket 325.

[0054] In the above embodiment, the first groove 3222 and the first protrusion 3242 cooperate to fix the second drive shaft 324 on the first drive shaft 322. Therefore, when the first drive shaft 322 is rotated by the drive assembly 31, the second drive shaft 324 also rotates, causing the second bracket 325 located on the second drive shaft 324 to move on the second drive shaft 324 and contact the support surface to stabilize the center of gravity of the liftable speaker and ensure that the liftable speaker will not tip over.

[0055] In some other embodiments, following the foregoing, the second drive shaft 324 has a plurality of second grooves 3243 recessed inward along the length of the second drive shaft 324. The plurality of second grooves 3243 are arranged around the axis of the second drive shaft 324. The bracket assembly 32 also includes a third drive shaft 326 and a third bracket 327. The third drive shaft 326 has a third thread 3261 on its exterior and a second protrusion 3262 engaged by the second grooves 3243 inside the third drive shaft 326. The third bracket 327 is located inside the second bracket 325 and is threadedly connected to the third drive shaft 326.

[0056] In the above embodiment, the second groove 3243 and the second protrusion 3262 cooperate to fix the third drive shaft 326 on the second drive shaft 324. Therefore, when the second drive shaft 324 rotates, the third drive shaft 326 also rotates, causing the third bracket 327 located on the third drive shaft 326 to move on the third drive shaft 326 and contact the support surface. This design, through the cooperation of the first bracket 323, the second bracket 325 and the third bracket 327, can, on the one hand, prevent the speaker body 1 from being prone to shaking or tipping due to the increased height of the display screen 2, thus avoiding the above problems and ensuring that the speaker body 1 operates stably in the predetermined position. On the other hand, it also allows the height-adjustable speaker to adapt to more complex application environments. For example, when the support surface is uneven, the bracket assembly 32 under the cooperation of the three brackets is driven by the drive assembly 31, and the extension length of the bracket assembly 32 has a wider range of choices, so that the bracket assembly 32 can better adapt to the terrain and stably support the speaker body 1 in the predetermined position.

[0057] Furthermore, in some other embodiments, the support assembly 32 may also include a greater number of drive shafts and supports. The structural principle can be referred to the foregoing content. The specific number can be determined according to the size of the speaker body 1 and the height of the display screen 2. As long as it can be ensured that the speaker body 1 will not tilt together with the display screen 2 when the display screen 2 is subjected to force, it is acceptable.

[0058] In this embodiment, please refer to Figure 7 and Figure 8 The support member 3 includes a contact block 5. The upper end of the contact block 5 is connected to the bottom of the bracket assembly 32. When the support member 3 is in the retracted state, the contact block 5 is embedded in the mounting cavity 11. In other words, when the bracket assembly 32 includes only the first bracket 323, the contact block 5 is connected to the end of the first bracket 323 near the opening of the mounting cavity 11; when the bracket assembly 32 includes the first bracket 323 and the second bracket 325, the contact block 5 is connected to the end of the second bracket 325 near the opening of the mounting cavity 11; when the bracket assembly 32 includes the first bracket 323, the second bracket 325 and the third bracket 327, the contact block 5 is connected to the end of the third bracket 327 near the opening of the mounting cavity 11. The above arrangement is mainly for the bracket assembly 32 to contact the support surface, avoiding direct contact between the bracket and the support surface, which is prone to wear and damage. The contact block 5 is provided to facilitate replacement, so as to ensure that the bracket assembly 32 is in contact with the support surface for a long time.

[0059] Furthermore, the lower end of the contact block 5 is formed with a cut surface, which is flush with the plane where the opening of the mounting cavity 11 is located when the support member 3 is in the retracted state. This setting is mainly to ensure the consistency and aesthetics of the appearance of the bracket assembly 32 with the speaker body 1 after it is stored.

[0060] Please refer to the following: Figure 2 and Figure 4 The speaker body 1 is provided with a dust cover 4 to cover the mounting cavity 11. This design is mainly to prevent dust or other contaminants from entering the mounting cavity 11 that houses the bracket assembly 32, which would affect the extension and retraction of the bracket assembly 32.

[0061] Regarding the quantity of support component 3, please refer to Figure 1 The number of support members 3 includes one or more. When the number of support members 3 is one, the size of the support member 3 is relatively large and it is applied to the middle of the side of the speaker body 1, which is relatively small.

[0062] When there are multiple support members 3, for example, in this utility model, there are two support members 3, which are symmetrically distributed on the same side of the speaker body 1 to stabilize the speaker body 1 in a predetermined position and prevent it from tipping over; of course, in some other embodiments, the number of support members 3 can also be three, four, etc., and the number of support members 3 can be determined according to the size of the speaker body 1.

[0063] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
