[0036] An embodiment of the present invention provides a microphone storage and fixing structure of a smart speaker, referring to Figure 1 and Figure 2 , including a sleeve assembly 2, a lifting bracket 3 and a charging circuit board 4.

[0037] The sleeve assembly 2 is used for plugging the microphone 1 ; the lifting bracket 3 is slidably installed in the sleeve assembly 2 and is used for carrying the microphone 1 .

[0038] The charging circuit board 4 is used to charge the microphone 1 . The charging circuit board 4 is located in the lifting bracket 3 . The sleeve assembly 2 is provided with a fixing portion extending into the lifting bracket 3 . The charging circuit board 4 is fixedly connected to the fixing portion.

[0039] The present embodiment improves the storage structure of the existing microphone 1, wherein the sleeve assembly 2 is provided with a slot for inserting the microphone 1. When the microphone 1 is stored, the microphone 1 can be directly inserted into the slot of the sleeve assembly 2. During the installation of the microphone 1, its end will abut against the lifting bracket 3, and the lifting bracket 3 will support the microphone 1. In the present embodiment, a charging circuit board 4 is arranged inside the lifting bracket 3. After the microphone 1 is installed in place, it will contact the charging circuit board 4 for charging. At the same time, in order to avoid the problem of damage to the charging circuit board 4 due to long-term reciprocating motion of the lifting bracket 3, in the present embodiment, although the charging circuit board 4 is located inside the lifting bracket 3, it is fixed to the sleeve assembly 2. Specifically, the sleeve assembly 2 is provided with a fixing portion, and the fixing portion extends straight into the lifting bracket 3 to be connected with the charging circuit board 4. In this way, the charging circuit board 4 is fixedly installed and its position does not change, thereby ensuring the stability of its installation and its service life.

[0040] Furthermore, the fixing part is configured as a plurality of columns 21, and the lifting bracket 3 is provided with avoidance grooves 31 corresponding to the plurality of columns 21. In this embodiment, the structure of the fixing part is simplified, and the fixing part is configured as a plurality of columns 21 extending into the lifting bracket 3. Figure 4 The lifting bracket 3 is provided with an avoidance groove 31 corresponding to the column 21, so that the setting of the column 21 does not affect the normal lifting action of the lifting bracket 3. At the same time, multiple columns 21 can be evenly distributed according to the shape of the charging circuit board 4, so as to be connected with the bottom of the charging circuit board 4, so that the charging circuit board 4 is evenly stressed and the installation is more stable.

[0041] Furthermore, the charging circuit board 4 and the column 21 can be fixed together by an existing method, such as a clamping structure of bosses and grooves, bonding with glue, or connecting with a threaded structure. In the present embodiment, the charging circuit board 4 and the column 21 are connected by a threaded structure. Specifically, corresponding threaded holes can be respectively opened on the charging circuit board 4 and the column 21, and then the corresponding threaded holes can be locked by screws to complete the connection between the charging circuit board 4 and the column 21. The structure has strong stability and is convenient for disassembly of the charging circuit board 4, which is convenient for later maintenance and replacement.

[0042] Furthermore, the lifting bracket 3 has a first state in which it slides downward relative to the sleeve assembly 2 and is locked in the sleeve assembly 2 when it is pressed by the microphone 1 for the first time, and a second state in which it slides upward relative to the sleeve assembly 2 to return to an initial position when it is pressed by the microphone 1 again.

[0043] Specifically, in the present embodiment, when the microphone 1 is stored, the microphone 1 can be inserted into the sleeve assembly 2 so that the bottom of the microphone 1 abuts against the lifting bracket 3. At this time, the microphone 1 is not installed in place, the lifting bracket 3 is in an active state, the microphone 1 is not in contact with the charging circuit board 4, and cannot be charged; then, the user can continue to press down the microphone 1, thereby driving the lifting bracket 3 to continue to descend. When the lifting bracket 3 descends to the first state, the lifting bracket 3 is locked, the end of the microphone 1 is in contact with the charging circuit board 4, the microphone 1 is installed in place, the microphone 1 can be charged normally, and the storage of the microphone 1 is completed.

[0044] When the microphone 1 needs to be taken out, the user only needs to press the microphone 1 again, and the lifting bracket 3 will be unlocked after being pressed by the microphone 1. After being unlocked, the lifting bracket 3 will slide upward to return to the initial position. After returning to the initial position, the lifting bracket 3 is in the second state. During this process, the microphone 1 will slide upward along the sleeve assembly 2 with the lifting assembly. When the lifting assembly is in the second state, the top of the microphone 1 protrudes out of the slot of the sleeve assembly 2, so that the user can take out the microphone 1 conveniently.

[0045] Furthermore, the lifting bracket 3 abuts against a reset spring 33, and the reset spring 33 is used to drive the lifting bracket 3 to reset from the first state to the second state. In this embodiment, the reset spring 33 is sleeved on the outside of the lifting bracket 3. When the lifting bracket 3 descends, the reset spring 33 will be compressed, so that the lifting bracket 3 will always be subject to the elastic restoring force of the reset spring 33. When the lifting bracket 3 is unlocked, the lifting bracket 3 will rise and reset in time under the elastic force of the reset spring 33, so as to facilitate the rapid pop-up of the microphone 1.

[0046] Furthermore, in this embodiment, the lifting bracket 3 is also connected to a guide and limit assembly, which is used to guide and limit the movement of the lifting bracket 3. The guide and limit assembly guides and limits the movement of the lifting bracket 3 to achieve locking and unlocking of the lifting bracket 3.

[0047] Specifically, refer to Figure 5 and Figure 6 The guide limit assembly includes a torsion spring 34 and a plurality of guide grooves provided on the lifting bracket 3. One end of the torsion spring 34 is hinged to the sleeve assembly 2, and the other end of the torsion spring 34 is clamped to the plurality of guide grooves.

[0048] The plurality of guide grooves include a first guide groove 35, a second guide groove 36 and a third guide groove 37 which are connected in sequence. The first guide groove 35 is opened obliquely from bottom to top along the lifting direction of the lifting bracket 3. The second guide groove 36 is formed into a V-shaped groove structure perpendicular to the lifting direction of the lifting bracket 3. The third guide groove 37 is opened from top to bottom along the lifting direction of the lifting bracket 3.

[0049] When the microphone 1 is not stored, the end of the torsion spring 34 is located in the first guide groove 35. When the microphone 1 is stored, the bottom of the microphone 1 abuts against the lifting bracket 3. The user continues to press down the microphone 1 to lock the lifting bracket 3. Specifically, after the lifting bracket 3 is pressed down by the microphone 1, the end of the torsion spring 34 slides upward along the first guide groove 35 and enters the second guide groove 36. When the end of the torsion spring 34 rises to the top, the lifting bracket 3 cannot continue to descend. The lifting bracket 3 descends into place. At this time, the user lets go and releases the locking of the microphone. Under the pressure of wind 1, the lifting bracket 3 will move upward due to the elastic force of the return spring 33, so that the end of the torsion spring 34 moves along the second guide groove 36. When the end of the torsion spring 34 moves to the tip of the V-shaped structure of the second guide groove 36, the direction of the second guide groove 36 changes greatly, providing a greater resistance to the torsion spring 34, so that the end of the torsion spring 34 stops moving, causing the lifting bracket 3 to stop rising, and the lifting bracket 3 is locked to the current position, that is, the first state. At this time, the microphone 1 is installed in place, and the bottom of the microphone 1 is in contact with the charging circuit board 4, and can be charged normally.

[0050] When the microphone 1 needs to be taken out, the user continues to press the microphone 1, and the lifting bracket 3 descends with the microphone 1. At this time, the moment the second guide groove 36 moves below the end of the torsion spring 34, the clamping force between the end of the torsion spring 34 and the tip of the V-shaped structure of the second guide groove 36 disappears. At this time, the lifting bracket 3 is unlocked, and the torsion spring 34 will continue to move along the second guide groove 36 until it moves to the bottom of the third guide groove 37. The lifting bracket 3 cannot continue to descend. The user releases his hand and releases the pressure on the microphone 1 and the lifting bracket 3. The lifting bracket 3 rises under the elastic force of the reset spring 33, and the end of the torsion spring 34 moves downward along the third guide groove 37 until it enters the first guide groove 35. The lifting bracket 3 returns to the initial position, that is, the second state. At this time, the microphone 1 is lifted up by the lifting bracket 3 to protrude out of the notch of the sleeve assembly 2, making it convenient for the user to take out the microphone 1.

[0051] Furthermore, at the connection between the first guide groove 35 and the third guide groove 37, the depth of the first guide groove 35 is lower than the depth of the third guide groove 37. This structure can form a boss structure at the connection between the first guide groove 35 and the third guide groove 37. The boss structure can prevent the end of the torsion spring 34 from sliding from the first guide groove into the third guide groove, that is, the torsion spring 34 can only move along a fixed direction: first guide groove → second guide groove → third guide groove, thereby preventing the torsion spring 34 from moving in the opposite direction and affecting the normal storage of the microphone 1.

[0052] Furthermore, the inner wall of the sleeve assembly 2 is provided with a conical slope 22, and the lifting bracket 3 is provided with a plurality of elastic claws 32 corresponding to the conical slope 22, and the elastic claws 32 have a clamping state of sliding downward along the conical slope 22 to clamp the microphone 1, and a loosening state of sliding upward along the conical slope 22 to loosen the microphone 1.

[0053] refer to Figure 2 In this embodiment, the conical inclined surface 22 is inclined toward the axis of the lifting bracket 3 along the descending direction of the lifting bracket 3. Therefore, during the descent of the lifting bracket 3, the elastic clamp 32 descends along the conical inclined surface 22, and the elastic clamp 32 is gradually compressed by the conical inclined surface 22, so that the elastic clamp 32 shrinks toward the surface of the microphone 1, clamping the microphone 1 to reach a clamped state; and when the lifting bracket 3 rises, the elastic clamp 32 rises along the conical inclined surface 22, and the compression force of the conical inclined surface 22 on the elastic clamp 32 is gradually reduced until it disappears, and the elastic clamp 32 opens under its own elastic force, thereby releasing the microphone 1 to reach a released state. The combined structure of the elastic clamp 32 and the conical inclined surface 22 is provided in this embodiment, which can further improve the installation stability of the microphone 1.

[0054] Furthermore, the outer wall of the microphone 1 is provided with a slot 11 corresponding to the elastic clamp 32. When the elastic clamp 32 is clamped, it can be further clamped in the slot 11 of the microphone 1, so that the clamping force between the elastic clamp 32 and the microphone 1 can be more stable, further improving the installation stability of the microphone 1.

[0055] Furthermore, a charging spring pin 41 is provided on the charging circuit board 4, and a charging contact 12 corresponding to the charging spring pin 41 is provided at the end of the microphone 1. In this embodiment, the charging structure of the charging circuit board 4 is a charging probe, which can provide a certain margin for the descent of the microphone 1 to ensure that the charging contact 12 of the microphone 1 can be in normal contact with the charging spring pin 41, and can also make the contact between the two closer to avoid poor contact affecting charging. The charging principle of the microphone 1 is a conventional technical means in this field, and is not an improvement point of the present application, and will not be described here.

[0056] Furthermore, in this embodiment, a Hall element may be provided to sense whether the microphone 1 is installed in place. Specifically, a magnet may be provided in the microphone 1, and a Hall sensor may be installed in the sleeve assembly 2. When the microphone 1 is installed in place, the magnet corresponds to the Hall sensor, and the Hall sensor senses a signal to confirm that the microphone 1 is installed in place. The sensing principle of the Hall sensor is a conventional technical means in this field, and is not an improvement point of the present application, and will not be described in detail here.

[0057] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
