Description

Technical Field

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

[0002] With the widespread adoption of smart devices, liftable screen speakers are widely used in various scenarios due to their convenient interaction methods. Existing liftable screen speakers require the screen to be raised to a height of approximately 1.2 meters to meet user operation needs. However, once the screen is raised, the force applied by the user and the upward shift of the center of gravity significantly reduce the overall stability of the speaker, especially in uneven or gravelly outdoor environments, further increasing the risk of tipping over.

[0003] To address the aforementioned issues, various manual anti-tipping bracket solutions have been proposed in the prior art. For example, deployable bracket structures are used around the speaker enclosure to provide support. However, these solutions typically require mounting holes or protruding structures on the speaker surface, compromising the speaker's aesthetic integrity and affecting its appearance. Furthermore, fixed brackets cannot adapt to different ground conditions, limiting their stability. Therefore, there is an urgent need for an anti-tipping speaker that maintains a clean appearance while automatically adjusting its support according to the usage scenario, thus balancing stability and aesthetics. Utility Model Content

[0004] The main purpose of this invention is to provide an automatic anti-tipping smart speaker, which aims to solve the problem that the speaker cannot adapt to ground conditions and has limited support stability.

[0005] To achieve the above objectives, this utility model proposes an automatic anti-tipping smart speaker, comprising:

[0006] Speaker body;

[0007] The support assembly includes a first support member and a second support member. The first support member is hinged to the side of the speaker body. The first support member has a sliding cavity, and the second support member is slidably installed in the sliding cavity.

[0008] A first driving member is disposed between the first support member and the second support member, and the first driving member drives the second support member to extend and slide relative to the first support member;

[0009] A control device is electrically connected to the first drive member to control the telescopic sliding of the second support member. Optionally, the control device includes a rotation detector disposed between the side of the speaker body and the first support member, the rotation detector detecting rotation of the first support member relative to the speaker body to control the activation of the first drive member.

[0010] Optionally, the control device further includes an extension detector disposed on the second support member, the extension detector detecting that the second support member contacts the external support surface, so as to control the first drive member to close.

[0011] Optionally, it further includes a second driving member, which is disposed between the speaker body and the first support member. The second driving member is electrically connected to the control device and is used to cause the first support member and the speaker body to rotate relative to each other.

[0012] Optionally, the second driving component is a second motor, the driving end of the second driving component is provided with transmission teeth, and the first support component is provided with an arc-shaped extended transmission groove. The transmission teeth cooperate with the transmission groove to drive the first support component to rotate.

[0013] Optionally, the first support member is a plate-like structure, and the surface area of ​​the first support member is equal to the surface area of ​​the rear side of the speaker body.

[0014] Optionally, a plurality of grooves are provided on the side of the speaker body connected to the support component; the number of support components corresponds to the number of grooves, each support component is embedded in the corresponding groove, and the outer surface of the support component is flush with the surface of the speaker body.

[0015] Optionally, the support assembly further includes a pivot shaft, which connects the speaker body and the first support member respectively. The first support member rotates relative to the speaker body around the pivot shaft to form a support angle.

[0016] Optionally, the first driving member is a first motor fixed to the first support member, and the driving end of the first motor extends and retracts and is connected to the second support member to drive the second support member to slide and extend relative to the first support member.

[0018] The beneficial effects of this utility model are as follows: it solves the problem that the overall support stability of the speaker decreases due to the user's operating force and the upward shift of the center of gravity after the speaker screen is raised, making it unable to adapt to ground conditions. By controlling the first driving component to start through the control device, the second support component extends relative to the first support component and abuts against the support surface, thereby achieving a stable anti-tipping effect.

[0037] One embodiment of this utility model provides an automatic anti-tipping smart speaker, see reference. Figures 1 to 6 The smart speaker includes a speaker body 1, a support assembly 2, a first drive member 3, and a control device 4. The smart speaker is used to play audio. The support assembly 2 includes a first support member 21 and a second support member 22. The first support member 21 is hinged to the side of the speaker body 1 and has a sliding cavity 211. The second support member 22 is slidably installed in the sliding cavity 211 to achieve the effect of telescopic extension. The first drive member 3 is disposed between the first support member 21 and the second support member 22 and drives the second support member 22 to telescopically slide relative to the first support member 21. The control device 4 is electrically connected to the first drive member 3 to control the telescopic sliding of the second support member 22.

[0038] This embodiment solves the problems of reduced overall speaker stability, inability to adapt to ground conditions, and unsightly appearance caused by the user's applied force and upward shift of the center of gravity after the speaker screen is raised. The control device 4 activates the first drive component 3, causing the second support component 22 to extend relative to the first support component 21 and abut against the support surface, thereby achieving a stable anti-tipping effect. Furthermore, the user can extend the second support component 22 to different lengths depending on the support surface conditions to ensure adequate contact with the support surface.

[0039] In this embodiment, the support component 2 is typically located on the back or side of the speaker body 1. During use, the support component 2 rotates with the speaker body 1 to form an angle, supporting the speaker body 1 and preventing it from tipping backward. The first drive component 3 drives the first support component 21 and the second support component 22 to automatically unfold or retract relative to each other, thereby achieving automatic anti-tipping of the smart speaker. This eliminates the need for the user to manually unfold the first and second support components, reducing user operation and improving ease of use. The control device 4 is electrically connected to the first drive component 3. By controlling the start and stop of the first drive component 3, the control device 4 controls the relative extension and retraction of the first and second support components 21 and 22, thereby ensuring sufficient contact between the support component 2 and the external support surface.

[0040] Further, refer to Figure 5 The control device 4 includes a rotation detector 41 disposed between the side of the speaker body 1 and the first support member 21. The rotation detector 41 detects the rotation of the first support member 21 relative to the speaker body 1 to control the activation of the first drive member 3. The rotation detector 41 is located at the connection between the first support member 21 and the speaker body 1. The rotation detector 41 can detect the change in distance between the side of the speaker body 1 and the first support member 21, thereby controlling the activation of the first drive member 3 after the first support member 21 rotates relative to the speaker body 1, so that the second support member 22 extends and abuts against the support surface, realizing automatic detection and extension.

[0041] When the user manually or automatically rotates the first support member 21, the physical distance between the first support member 21 and the side of the speaker body 1 changes as the rotation angle increases. The rotation detector 41 detects this distance change in real time using non-contact measurement technology. The rotation detector 41 can be an infrared ranging sensor or a Hall sensor, etc. Specifically, an infrared transmitting module and a receiving module, or a Hall sensor and a magnet assembly, are respectively installed at the corresponding positions on the side of the speaker body 1 and the first support member 21. When the first support member 21 and the side of the speaker body 1 are in a closed state, the initial distance detected by the rotation detector 41 is a fixed value; when the first support member 21 is rotated, the relative position between the transmitting module and the receiving module shifts, causing a change in the received signal strength or magnetic field strength. When the rotation detector 41 detects that the distance change between the first support member 21 and the speaker body 1 continues to exceed a threshold and remains for a set time, it determines that the user has actively unfolded the bracket, triggering the first driving member 3 to start and drive the second support member 22 to extend outward.

[0042] Furthermore, the control device 4 also includes an extension detector 42 disposed on the second support member 22. The extension detector 42 detects that the second support member 22 contacts the external support surface, thereby controlling the first drive member 3 to close. In this embodiment, the second support member 22 is extended by the first drive member 3, so that after the first support member 21 rotates, the second support member 22 can extend to match the distance from the support assembly 2 to the external support surface, thereby achieving stable contact. The extension detector 42 is disposed at the bottom of the second support member 22. The extension detector 42 is used to detect whether the second support member 22 is in full contact with the support surface and control the first drive member 3 to stop in time, ensuring that the second support member 22 contacts the support surface and preventing the second support member 22 from extending excessively, causing the speaker body 1 to tilt.

[0043] Specifically, the extension detector 42 can determine whether the second support member 22 is in sufficient contact with the support surface by detecting the pressure between the second support member 22 and the external support surface. When the bottom of the second support member 22 contacts the ground and is subjected to a reaction force, the ground reaction force causes the extension detector 42 to generate an electric charge. When the extension detector 42 detects that the pressure exceeds a threshold, the extension detector 42 outputs a voltage signal to control the first drive member 3 to close, and the second support member 22 stops extending. The extension detector 42 adjusts the extension length of the second support member 22 by detecting the pressure of the second support member 22, thereby adapting to different ground conditions, such as different support pressures on soft, gravel, or hard ground, and ensuring the stability of the support. It should be noted that a pressure detector identical to the extension detector 42 can also be set on the outer surface of the first support member 21. The pressure detector is used to control the second support member 22 to retract into the sliding cavity 211. When the user finishes using the device, the user presses within the range of the pressure detector. The pressure between the user's finger and the first support member 21 exceeds the threshold. The pressure detector outputs a voltage signal to control the first drive member 3 to drive in the reverse direction, causing the second support member 22 to retract into the sliding cavity 211. Simultaneously, the user can press the first support member 21 and cover the side of the speaker body 1 with the first support member 21.

[0044] Further, refer to Figure 6 In another embodiment, the automatic anti-tipping smart speaker further includes a second driving member 5, which is disposed between the speaker body 1 and the first support member 21. The second driving member 5 is electrically connected to the control device 4 and is used to cause the first support member 21 and the speaker body 1 to rotate relative to each other. In this embodiment, the second driving member 5 is electrically connected to the control device 4, thereby enabling the control device 4 to control the second driving member 5 to rotate and open the support member 2 relative to the speaker body 1. The second driving member 5 is respectively disposed on the speaker body 1 or the first support member 21, so that when the second driving member 5 is activated, it drives the first support member 21 and the speaker body 1 to rotate and open relative to each other, thereby achieving the effect of automatic anti-tipping.

[0045] Furthermore, the second driving component 5 is a second motor. The driving end of the second driving component 5 is provided with a transmission tooth 51. The first support member 21 is provided with an arc-shaped extending transmission groove 212. The transmission tooth 51 engages with the transmission groove 212 to drive the first support member 21 to rotate. A driving shaft extends from the driving end of the second driving component 5, and the transmission tooth 51 is mounted on the driving shaft. When the second driving component 5 starts, it drives the transmission tooth 51 to rotate circumferentially. The transmission groove 212 is arc-shaped and located on the side of the first support member 21 near the speaker body 1. The transmission groove 212 is approximately C-shaped, and its position is opposite to the transmission tooth 51. Multiple tooth grooves are provided on the transmission groove 212 so that the transmission tooth 51 can mesh with the multiple tooth grooves on the transmission groove 212 for transmission.

[0046] In the initial state, the first support member 21 is in contact with the speaker body 1, and the transmission gear 51 is located at the lower end of the transmission groove 212. When the second drive member 5 is activated, the transmission gear 51 rotates and moves relative to the speaker body 1 along the arc-shaped transmission groove 212. Since the position of the transmission gear 51 is fixed, it moves relative to the upper end of the transmission groove 212, causing the first support member 21 to unfold synchronously relative to the speaker body 1. The second drive member 5 is connected to the control device 4, so that the control device 4 can directly control the activation of the second drive member 5. When the first support member 21 rotates to a suitable angle, the control device 4 controls the second drive member 5 to stop. By controlling the rotation detector 41 and the extension detector 42, the first drive member 3 is activated to drive the second support member 22 to extend relative to the first support member 21, thereby stabilizing the speaker body 1.

[0047] Furthermore, the first support member 21 is a plate-like structure, and its surface area is equal to the surface area of ​​the rear side of the speaker body 1. In this embodiment, the first support member 21 is a plate-like structure, and its length and width dimensions are the same as the side dimensions of the speaker body 1. This allows the first support member 21 to completely fit against the rear side of the speaker body 1 when it is folded, resulting in a smooth surface without protrusions or depressions, thus improving the speaker's aesthetics when not unfolded. In addition, the second support member 22 is also a plate-like structure. The contact area between the second support member 22 and the supporting surface is larger than that of a single-point support, resulting in higher support stability.

[0048] Further, refer to Figure 2 and Figure 3The speaker body 1 has several grooves 11 on the side connected to the support component 2. The number of support components 2 corresponds to the number of grooves 11, with each support component 2 embedded in its corresponding groove 11. The outer surface of the support component 2 is flush with the surface of the speaker body 1. In this embodiment, the support component 2 is a plate-like structure. The first support member 21 has the same side area as the speaker body 1, and there is one groove 11 with a depth equal to the thickness of the first support member 21. When the first support member 21 is not unfolded, the second support member 22 is housed in the sliding cavity 211 of the first support member 21. The first support member 21 is embedded in the groove 11, making its surface flush with the surface of the speaker body 1. The support component 2 is completely housed in the groove 11, preventing accidental damage when not in use and improving the overall aesthetics of the speaker. In other embodiments, the side of the speaker body 1 may also be provided with multiple grooves 11. For example, when multiple support components 2 are provided and are spaced strip-shaped support plates, multiple grooves 11 are provided and correspond one-to-one with multiple support components 2, and each support component 2 can be completely housed in the groove 11.

[0049] Furthermore, the support assembly 2 also includes a rotating shaft 23, which connects the speaker body 1 and the first support member 21. The first support member 21 rotates relative to the speaker body 1 around the rotating shaft 23 to form a support angle. In this embodiment, the rotating shaft 23 passes through the end of the first support member 21 and the speaker body 1, causing the first support member 21 to rotate relative to the speaker body 1 around the rotating shaft 23, forming a certain angle between the first support member 21 and the speaker body 1. This allows the support assembly 2, the speaker body 1, and the support surface to form a triangle, improving support stability. Two rotating shafts 23 are provided, one on each side of the first support member 21. Specifically, one end of the rotating shaft 23 is fixed relative to the first support member 21, and the other end is inserted into a hole in the speaker body 1 to rotate within that hole. It should be noted that the rotational connection between the first support member 21 and the speaker body 1 can also be achieved through a hinge connection or a rotating ball connection. For example, a rotating ball is fixedly provided at the end of the first support member 21, and a hemispherical rotating groove is provided at the corresponding position of the speaker body 1. The rotating ball is inserted into the rotating groove and rotates within the rotating groove, thereby realizing the rotational unfolding of the first support member 21.

[0050] Further, the first driving member 3 is a first motor fixed to the first support member 21. The driving end of the first motor extends and retracts and is connected to the second support member 22 to drive the second support member 22 to slide and extend relative to the first support member 21. In this embodiment, the first driving member 3 is fixed to the first support member 21. The driving end of the first driving member 3 is provided with a retractable rod. The end of the rod is connected to the second support member 22. When the first driving member 3 is activated, the second support member 22 is pushed out of the sliding cavity 211, so that the first support member 21 and the second support member 22 are relatively unfolded. There are two first driving members 3. The two first driving members 3 are respectively arranged at intervals on the first support member 21 and respectively connected to the second support member 22. The two first driving members 3 are activated or deactivated simultaneously to drive the first support member 21 and the second support member 22 to slide relative to each other.

[0051] Furthermore, the speaker body 1 is equipped with a display screen 6 and a lifting device 7. The lower end of the lifting device 7 is connected to the speaker body 1, and the upper end of the lifting device 7 is connected to the display screen 6. The lifting device 7 is electrically connected to the control device 4. The lifting device 7 is used to move the display screen 6 up and down, allowing the display screen 6 to be adjusted in height according to the user's needs. The lifting device 7 is rotatably connected to the display screen 6, allowing the lifting device 7 to adjust the support angle of the display screen 6, facilitating the user to adjust the viewing angle. When the display screen 6 needs to be used, the lifting device 7 raises the display screen 6 via a motor or telescopic rod structure. When use is finished, the lifting device 7 retracts into the speaker body 1, and the display screen 6 is placed against the top of the speaker body 1.

[0052] Specifically, the lifting device 7 is a height-adjustable and telescopic rod-shaped structure. The lifting device 7 is electrically connected to the control device 4. Through program control within the speaker body, the lifting device 7 is linked with the two driving components via the control device 4. When the user uses the speaker, the lifting device 7 raises the display screen 6. Simultaneously, the upward signal from the lifting device 7 is transmitted to the control device 4, which controls the second driving component 5 to activate. Through the cooperation of the transmission gear 51 and the transmission groove 212, the support assembly 2 rotates and unfolds relative to the speaker body. The rotation detector 41 detects the rotation of the support assembly 2, causing it to send a signal to the first driving component 3 and activate it. The first support component 21 and the second support component 22 slide and unfold, contacting the ground to support the speaker body 1. The extension detector 42 detects the second support component 22 contacting the ground, controlling the first driving component 3 to close, thus enabling the entire speaker to automatically unfold without tipping over. Similarly, after the user finishes using the device, the lifting device 7 is lowered to retract the display screen 6. The lowering signal of the lifting device 7 is sent to the control device 4, which then controls the first drive member 3 and the second drive member 5 to drive in opposite directions, causing the second support member 22 to retract into the sliding cavity 211. The support assembly 2 then rotates and embeds itself into the groove 11 on the speaker body 1. This allows the bracket assembly to automatically unfold or retract, achieving the speaker's automatic anti-tipping function.

[0053] In other embodiments, the retraction of the support assembly may not be linked by the lifting device 7. For example, a button for controlling the retraction can be provided on the speaker body. After use, the user presses the button, which controls the first drive member 3 and the second drive member 5 to drive in opposite directions, so that the second support member 22 retracts into the sliding cavity 211 and the first support member 21 rotates and fits into the groove 11.

[0054] 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.
