[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, a preferred embodiment of the present invention provides a smart speaker, which includes a speaker body 100 and an angle adjustment mechanism installed on one side of the speaker body 100. The angle adjustment mechanism includes a one-way bearing 1, a first bracket 2, a clutch assembly 3, and a second bracket 4 fixedly connected to the speaker body 100. The speaker body 100 is installed on the wall of a conference room, a theater, etc. through the angle adjustment mechanism. In this embodiment, the first bracket 2 is installed on the wall. When the speaker body 100 is flipped in a direction away from the wall, the speaker body 100 can be rotated to a certain angle relative to the wall and remain in a relatively fixed state. When the speaker body 100 is flipped in a direction close to the wall, the angle between the speaker body 100 and the wall gradually decreases until it is reset.

[0035] Specifically, Figure 4 Also see Figure 1 , Figure 2 as well as Figure 3As shown, the one-way bearing 1 is used to allow the speaker body 100 to rotate a certain angle and maintain a relatively fixed state. The one-way bearing 1 includes a bearing seat 11, and a one-way shaft 12. The one-way shaft 12 can be installed on the bearing seat 11 in a unidirectional manner, that is, the one-way shaft 12 can rotate freely in one rotation direction, and is locked in another rotation direction. The rotation direction in which the one-way shaft 12 can rotate relative to the bearing seat 11 is a first rotation direction, that is, the direction in which the speaker body 100 flips away from the wall. The rotation direction in which the one-way shaft 12 is locked relative to the bearing seat 11 is a second rotation direction, that is, the direction in which the speaker body 100 flips toward the wall. The one-way bearing 1 can adopt a common structure in the prior art, which will not be repeated here.

[0036] In this embodiment, the one-way rotating shaft 12 is drivingly connected to the first bracket 2, and the bearing seat 11 is fixedly connected to the second bracket 4; when the speaker body 100 is in the initial position, that is, the speaker body 100 is superimposed on the wall, the angle between the first bracket 2 and the second bracket 4 is the smallest, and the smallest angle is the initial position angle. When the speaker body 100 is flipped to the final position, the angle between the first bracket 2 and the second bracket 4 is the largest, and the largest angle is the final position angle.

[0037] In this embodiment, the one-way bearing 1 also includes a limiter 13 protruding from the bearing seat 11, and the limiter 13 is a roughly cylindrical structure. When the first bracket 2 rotates relative to the bearing seat 11, the limiter 13 can touch the driving mechanism 32, so that the locking mechanism 31 locks or releases the one-way rotating shaft 12. When the speaker body 100 is flipped in a direction away from the wall, the limiter 13 can touch the driving mechanism 32 so that the locking mechanism 31 releases the one-way rotating shaft 12. When the speaker body 100 is flipped in a direction close to the wall, the limiter 13 can touch the driving mechanism 32 so that the locking mechanism 31 locks the one-way rotating shaft 12.

[0038] like Figure 5 , Figure 6 Also see Figure 1 , Figure 3 As shown, the first bracket 2 is used to drive the one-way rotating shaft 12 to rotate, and is in transmission connection with the one-way rotating shaft 12. The first bracket 2 includes a bracket body 21, and a mounting hole 22 that penetrates the bracket body 21. The bracket body 21 is generally a rectangular block structure, and the one-way rotating shaft 12 is inserted into the mounting hole 22. A sliding groove 221 is provided on one side of the inner wall of the mounting hole 22, and the locking block 311 in the clutch assembly 3 is slidably mounted in the sliding groove 221.

[0039] like Figure 5 , Figure 7 , Figure 8 , Fig. 9 Also see Figure 1 , Figure 3 As shown, the clutch assembly 3 is transmission-connected between the one-way rotating shaft 12 and the first bracket 2, and is used to achieve transmission connection or disengagement between the first bracket 2 and the one-way rotating shaft 12. When the first bracket 2 is transmission-connected with the one-way rotating shaft 12, that is, the clutch assembly 3 is in a closed state, the one-way rotating shaft 12 is fixedly connected to the first bracket 2, and the first bracket 2 can drive the one-way rotating shaft 12 to rotate; when the first bracket 2 is disengaged from the one-way rotating shaft 12, that is, the clutch assembly 3 is in an open state, the one-way rotating shaft 12 is disengaged from the first bracket 2, and the first bracket 2 can be reset.

[0040] When the speaker body 100 is in the initial position, that is, the speaker body 100 is superimposed on the first bracket 2, the clutch assembly 3 is in a closed state. At this time, when the speaker body 100 is flipped in the direction away from the wall, the angle between the speaker body 100 and the wall gradually increases, and the clutch assembly 3 is still in a closed state. When the angle between the first bracket 2 and the second bracket 4 is close to the final position angle, the clutch assembly 3 is in an open state. At this time, the speaker body 100 is flipped in the direction close to the wall so that the angle between the speaker body 100 and the first bracket 2 gradually decreases. When the angle between the first bracket 2 and the second bracket 4 is close to the initial position angle, the clutch assembly 3 is in a closed state.

[0041] In this embodiment, Figure 5 , Figure 7 , Figure 8 , Fig. 9 Also see Figure 1 , Figure 3As shown, the clutch assembly 3 includes a locking mechanism 31, a driving mechanism 32, a limiting piece 33, a first cover 34 and a second cover 35. The locking mechanism 31 is installed on the first bracket 2, and is used to lock or release the one-way rotating shaft 12. The locking mechanism 31 includes a locking block 311, a pushing member 312 and an elastic reset member 313. The locking block 311 is a roughly square-shaped structure, which can be reciprocatingly installed in the sliding groove 221. When the locking block 311 moves toward the one-way rotating shaft 12, the locking block 311 can be pressed against the one-way rotating shaft 12, and the first bracket 2 can drive the one-way rotating shaft 12 to rotate. When the locking block 311 moves away from the one-way rotating shaft 12, the locking block 311 is out of contact with the one-way rotating shaft 12, and at this time, rotating the first bracket 2 along the second rotation direction can reset the first bracket 2. The pusher 312 is convexly disposed on the locking block 311 and can be in sliding contact with the paddle 321 in the driving mechanism 32. When the paddle 321 rotates, it can push the pusher 312 to drive the locking block 311 to reciprocate in the sliding groove 221. The elastic reset member 313 is used to enable the locking block 311 to automatically reset, and is connected between the locking block 311 and the bracket body 21. In this embodiment, the elastic reset member 313 is connected between the locking block 311 and the inner wall of the sliding groove 221. Preferably, the elastic reset member 313 is a spring.

[0042] Preferably, if Figure 5 As shown, a cylindrical gear 14 is mounted on the one-way rotating shaft 12, and an inner tooth 3111 is provided on the locking block 311 to mesh with the cylindrical gear 14. The structure of the cylindrical gear 14 and the inner tooth 3111 can make the locking block 311 lock the one-way rotating shaft 12 more firmly, and effectively prevent the first bracket 2 from slipping during rotation.

[0043] like Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 Also see Figure 1 , Figure 3 As shown, the driving mechanism 32 is used to drive the locking block 311 to press or release the one-way rotating shaft 12, and includes a paddle 321 and a paddle seat 322, and the paddle 321 is rotatably mounted on the paddle seat 322. The paddle 321 includes a paddle body 3211 in a circular shape, and a first protrusion 3212, a second protrusion 3213 and a pushing portion 3214 protruding on the side wall of the paddle body 3211. When the first bracket 2 rotates along the first rotation direction, the limit member 13 can touch the first protrusion 3212 or the second protrusion 3213, so that the locking mechanism 31 releases or locks the one-way rotating shaft 12. The protrusion height of the pushing portion 3214 gradually increases along the rotation direction of the one-way rotating shaft 12, and it is used to push the pushing member 312, thereby driving the locking block 311 to move.

[0044] When the speaker body 100 is turned over in a direction away from the wall, the limiting member 13 can push the first protrusion 3212 so that the pushing portion 3214 pushes the pushing member 312, thereby driving the locking block 311 to move to the side away from the one-way shaft 12, so that the locking block 311 releases the one-way shaft 12. At this time, when the speaker body 100 is turned over in a direction close to the wall, the limiting member 13 can push the second protrusion 3213 so that the locking block 311 moves to the side of the one-way shaft 12 under the action of the elastic reset member 313, thereby causing the locking block 311 to lock the one-way shaft 12, and the speaker body 100 is reset.

[0045] Preferably, a first positioning notch 3215 and a second positioning notch 3216 are provided on the pushing portion 3214. When the locking block 311 locks the one-way rotating shaft 12, the pushing member 312 and the first positioning notch 3215 abut against each other. When the locking block 311 releases the one-way rotating shaft 12, the pushing member 312 and the second positioning notch 3216 abut against each other. The structure of the first positioning notch 3215 and the second positioning notch 3216 can make the pushing portion 3214 and the pushing member 312 more stable when abutting against each other.

[0046] The paddle seat 322 includes a paddle seat body 3221, a receiving hole 3222 extending through the paddle seat body 3221, and a limiting notch 3223 provided on one side of the inner wall of the receiving hole 3222. The push portion 3214 is rotatably disposed in the limiting notch 3223. The structure of the limiting notch 3223 can limit the rotation range of the paddle 321 in the paddle seat 322.

[0047] like Fig.11 Also see Figure 8 , Fig. 9 As shown, the limit piece 33 is installed at one end of the paddle seat 322 close to the bearing seat 11, and is provided with an arc-shaped limit groove 331. The limit piece 13 can be slidably inserted into the limit groove 331. The structure of the limit piece 33 can limit the rotation angle of the first bracket 2 relative to the bearing seat 11.

[0048] like Figure 2 Also see Figure 1 As shown, the first cover 34 is installed at the end of the paddle seat 322 away from the bearing seat 11, and the second cover 35 is installed at the end of the first bracket 2 away from the bearing seat 11, and the second cover 35 is opposite to the mounting hole 22. The structure of the first cover 34 and the second cover 35 can seal the internal components of the clutch assembly 3.

[0049] Using the smart speaker as described in the above embodiment, since the angle adjustment mechanism in the smart speaker adopts the structure of a one-way bearing 1 and a clutch assembly 3, the one-way bearing 1 can make the speaker body 100 rotate a certain angle relative to the wall and maintain a relatively fixed state, and the clutch assembly 3 can control the speaker body 100 to achieve reset. The above structure is compact, small in size, easy to adjust the angle and reliable to use.

[0050] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
