As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The embodiment of the invention provides a sound equipment telescopic structure applicable to a plane display device, which can realize the adjustment of the position of the sound equipment. A flat display device having the telescopic structure is also provided. The flat panel display device may be a liquid crystal television, a plasma television, an organic light emitting diode television or a display. The following describes the sound expansion structure and its application in detail.

Referring to fig. 1 to 3, a sound expansion structure 10 according to an embodiment of the present invention can be mounted on a body 20 of a flat panel display device to drive a sound 30 to extend or retract.

The acoustic telescopic structure 10 includes a motor assembly 110; the transmission assembly 120 is connected with the motor assembly 110; a rotating shaft assembly 130 connected with the transmission assembly 120; a driving wheel 140 rotated by the rotation shaft assembly 130; a sound connection bracket 150 for connecting the sound 30; a transmission member 160 connecting the driving wheel 140 and the audio connecting bracket 150, and a guide rail assembly for guiding the moving direction of the audio connecting bracket 150. The motor assembly 110 drives the transmission assembly 120, the transmission assembly 120 drives the rotating shaft assembly 130 to rotate, the rotating shaft assembly 130 drives the driving wheel 140 to rotate, the driving wheel 140 drives the sound equipment connecting bracket 150 to move along the guide rail assembly through the transmission member 160, and the sound equipment connecting bracket 150 can drive the sound equipment 30 to synchronously move. The motor assembly 110 can drive the driving wheel 140 to rotate forward or backward, and the driving wheel 140 drives the sound connection bracket 150 to move back and forth through the transmission member 160 when rotating, which can be far away from or close to the driving wheel 140.

In this embodiment, the acoustic telescopic structure 10 may be installed inside the main body 20 of the flat display device. The speaker 30 is extendable and retractable inside the main body 20 through the speaker telescopic structure 10. As shown in fig. 6, the main body 20 may be generally formed by assembling a display module 210 mounted with a screen 230 and a rear case 220. In addition, the main body 20 may further include a front frame, wherein the front frame is disposed on a side of the display module 210 away from the rear housing.

The operation of the motor assembly 110 can be controlled by function keys on the flat panel display device, or can be signaled by a control device (such as a remote controller), and the signal can be an infrared, radio frequency or bluetooth signal, or can be controlled by the APP of the flat panel display device. When the flat display device is powered on or after a period of time, the motor assembly 110 rotates forward or backward according to the control signal, and finally the sound 30 is automatically extended or retracted. In addition, the operation of the motor assembly 110 can be controlled by software inside the flat display device according to requirements. A control circuit board having a control chip for controlling the operation of the motor assembly 110 may be disposed in the inner space of the body 20. In addition, the sound 30 can be controlled to automatically extend or retract not only when the liquid crystal television is turned on or off, but also when the liquid crystal television is not operated, namely, the sound 30 is not used for matching with the television but used as a common sound box.

The flat panel display device at least comprises a liquid crystal display television, a plasma display television, an organic light emitting diode television, a liquid crystal display, a plasma display and an organic light emitting diode display. The sound box 30 can be located on the display ground side, the display sky side, or on one or two of the left and right sides, so under the constraint of the guide rail assembly, the direction of the telescopic motion of the sound box connecting support 150 is not limited to vertical or horizontal, and can also be in the direction of an inclined angle, and is not limited to a group of sound box telescopic structures 10, and when the number of the sound boxes 30 is greater than 1, a plurality of groups of sound box telescopic structures 10 can be arranged. Of course, when the number of the acoustic devices 30 is 1, a plurality of sets of the telescopic mechanisms 130 may be provided. In the embodiment of the present invention, the sound 30 located on the display ground side is taken as an example for explanation.

The sound horn is usually fixed in the below of display screen in traditional display device, and towards observing the visual angle, provides good preceding sound effect, however, under the off-state, the display screen below sets up great horizontal strip stereo set loudspeaker, structural seem obtrusive, heavy, influences the visual effect of full face screen or narrow frame. As shown in fig. 1, in the present embodiment, the sound equipment retractable structure 10 can drive the sound equipment 30 to retract into the main body 20, and the front of the flat panel display device can achieve the visual effect of a full screen or a narrow frame. As shown in fig. 3, the sound expansion and contraction structure 10 extends the sound 30 to the display ground side, thereby achieving a preferable sound output effect.

In some embodiments, the transmission member 160 is a twisted rope, wherein one end of the twisted rope is connected to the sound connection bracket 150, and the other end of the twisted rope is connected to the driving wheel 140 and winds a wire on the driving wheel 140 to take up or pay out the wire. As seen from left to right in fig. 1, the drive wheel 140 can be configured to wind the twisted rope in a counterclockwise direction, unwind the rope in a reverse direction, or vice versa. In this manner, the length of the strand between the drive wheel 140 and the audio interface bracket 150 is reduced or increased to effect movement of the audio interface bracket 150 toward or away from the drive wheel 140, i.e., to effect retraction or extension movement of the audio 30. The extension or retraction of the speaker 30 is achieved by the retraction and extension of the twisted rope, which requires less space inside the body 20 than a rail-type transmission mechanism. The drive wheel 140 is a wheel-shaped element capable of winding the ragger rope. Further, a wire groove may be provided on the circumference of the driving wheel 140 to accommodate the wound wire.

In some embodiments, the motor assembly 110 includes a driving motor 111 and a motor bracket 112 fixing the driving motor 111. The motor bracket 112 is fixed to the body 20 to support the driving motor 111.

Further, in some embodiments, the transmission assembly 120 includes a driving gear 121 fixed to an output end of the driving motor 111, and a driven gear 122 mounted to the rotation shaft assembly 130. As shown in fig. 1, the driving gear 121 is driven by the output end of the driving motor 111 to rotate, and then the driven gear 122 is driven to rotate, and the driven gear 122 drives the driving wheel 140 to rotate through the rotating shaft assembly 130. The driving motor 111 transmits torque to the driving wheel 140 through a gear transmission structure, and has a simple and compact structure.

Further, in some embodiments, the rotation shaft assembly 130 includes a rotation shaft 131 and a rotation shaft bracket 132 supporting the rotation shaft 131, and the driven gear 122 and the driving wheel 140 are fixed to the rotation shaft 131. As shown in fig. 1, the shaft bracket 132 is fixed to the body 20 and supports the shaft 131. When the driven gear 122 is driven by the driving gear 121 to rotate, the driven gear 122 can drive the rotating shaft 131 to rotate, and the rotating shaft 131 drives the driving wheel 140 on the rotating shaft to rotate, so that the rope winding and unwinding are realized.

The number of the driving wheels 140 on the rotating shaft 131 can be arranged in different manners. The following examples are given.

For example, in the embodiment shown in fig. 1, one driving wheel 140 is fixed to each end of the rotating shaft 131, and each of the two driving wheels 140 is connected to one end of the sound connecting bracket 150 through a transmission member 160. The transmission members 160 are mounted at the two positions in the same manner. The driving gear 121 is fixed to the middle of the rotating shaft 131. Thus, when the rotation shaft 131 rotates, the two driving wheels 140 are driven to rotate simultaneously, and the sound connecting bracket 150 can be lifted from the two ends of the sound connecting bracket 150 simultaneously, so that the sound connecting bracket 150 operates stably.

Further, when the two ends of the rotating shaft 131 are respectively fixed with one driving wheel 140, the axial direction of the rotating shaft 131 may be completely consistent with the length direction of the sound connecting bracket 150, and the axial length of the rotating shaft 131 may be set to be slightly smaller than or equal to the length of the sound connecting bracket 131.

For another example, in other embodiments, as shown in fig. 4 and 5, the rotating shaft 131 is fixed with one driving wheel 140 only at the middle portion thereof, and accordingly, the transmission member 160 is provided at only one position and is a twisted rope. The point of attachment of audio interface bracket 150 to actuator 160 is located in the middle of audio interface bracket 150. Therefore, when the sound connection bracket 150 is pulled by the twisted rope, the stress point of the sound connection bracket 150 is located in the middle of the sound connection bracket 150. Thus, the sound connection bracket 150 can be smoothly pulled up, and the number of the twisted ropes and the driving wheels 140 can be reduced. In addition, when the audio connection bracket 150 is lifted from the middle of the audio connection bracket 150, the rotating shaft 40 only needs to be short, and only 1 driving wheel 140 can be installed, that is, the length of the rotating shaft 40 does not need to be set long. Referring to fig. 4 and 5, the length of the rotation shaft 131 is much smaller than that of the sound connection bracket 150, the driving wheel 140 and the driven gear 122 are fixed side by side to the middle of the rotation shaft 40, and the driving member 160 lifts the sound connection bracket 150 from the middle of the sound connection bracket 150.

It is to be understood that the number of the shaft brackets 132 is not limited, and is selected according to the fixing requirement and the installation space. In the embodiment shown in fig. 2, each driving wheel 140 is provided with a shaft bracket 132 at both sides thereof, and the driven gear 122 is provided with a shaft bracket 132 at both sides thereof, so that the shaft 131 is stably supported. As in the embodiment shown in fig. 4 and 5, one rotation shaft bracket 132 is provided to the left side of the driving wheel 140, and one rotation shaft bracket 132 is provided to the right side of the driven gear 122.

In some embodiments, as shown in fig. 2, 3, 5, and 10, the rail assembly includes a rail 172. Further, as shown in fig. 6, the guide rail 172 is slidably engaged with the sound connection bracket 150, and the guide rail 172 includes a first guide section 1721 and a second guide section 1722 connected with each other, and the guide directions of the first guide section 1721 and the second guide section 1722 are perpendicular to each other. Therefore, when the sound connection bracket 150 is driven to move back and forth, the movement track is limited by the first guide section 1721 and the second guide section 1722, and two movements in the directions perpendicular to each other can be realized, so that the sound box 30 moves vertically downwards first and then moves forwards along the horizontal direction, the movement effect is as shown in fig. 7 to 9, and finally, the sound box 30 can move forwards to the position flush with the screen 230 of the flat panel display device, and a good sound production effect is realized.

In addition, an obtuse angle may be formed between the first guide section 1721 and the second guide section 1722, so that the sound 30 can move vertically downward first and then the sound 30 can move obliquely forward.

Further, in some embodiments, as shown in fig. 6, an arc-shaped guide segment 1723 is disposed between first guide segment 1721 and second guide segment 1722 of guide rail 172. First guide section 1721, second guide section 1722 and arc-shaped guide section 1723 are connected into a whole to form a substantially L-shaped guide rail, so that movement of sound connection bracket 150 in two directions perpendicular to each other is realized. Through setting up arc direction section 1723, realize stereo set linking bridge 150 smooth transition to second direction section 1722 from first direction section 1721.

In some embodiments, the rail assembly includes rails 172 arranged in pairs, the rails 172 slidably engaging the audio interface bracket 150.

For example, as shown in fig. 1, the main body 20 of the flat display device may be provided with 2 guide rails 172, each of which is slidably fitted to the upper surface of an end portion of the audio connection bracket 150.

For another example, as shown in fig. 10, the main body 20 of the flat display device may be provided with 2 guide rails 172, each of which is slidably fitted to a side surface of an end portion of the acoustic connection bracket 150. Thus, the movement locus of the sound connection bracket 150 is restrained from both end portions of the sound connection bracket 150, and the sound connection bracket 150 is ensured to run stably. At this time, as shown in fig. 6, the sound connection bracket 150 is further provided with a sliding shaft 152 for slidably engaging with the guide rail 172. It is understood that the number of rails 172 in the same rail assembly is not limited to 2, and may be more than two.

Referring to fig. 11 and 12, in another embodiment of the present invention, the sound expansion and contraction structure 10 includes a motor assembly 110; the transmission assembly 120 is connected with the motor assembly 110; a rotating shaft assembly 130 connected with the transmission assembly 120; a driving wheel 140 rotated by the rotation shaft assembly 130; a sound connection bracket 150 for connecting the sound 30; a transmission member 160 connecting the driving wheel 140 and the audio connecting bracket 150, and a guide rail assembly for guiding the moving direction of the audio connecting bracket 150.

In this embodiment, the structures of the motor assembly 110, the transmission assembly 120, the rotating shaft assembly 130, the sound connecting bracket 150 and the guide rail assembly may be completely the same as those of the previous embodiments. Specifically, referring to fig. 11 and 12 together, the motor assembly 110 includes a driving motor 111 and a motor bracket 112. The shaft assembly 130 includes a shaft 131 and a plurality of shaft brackets 132. The transmission assembly 120 includes a driving gear 121 fixed to an output end of the driving motor 111 and a driven gear 122 fixed to a rotation shaft 131.

The difference is that the driving wheel 140 is a gear wheel, or the driving wheel 140 is a wheel-shaped element with a tooth structure on the outer ring. The transmission member 160 is a gear belt. One end of the gear belt is connected to the sound attachment bracket 150 and the other end is engaged with the tooth structure on the drive wheel 140. Thus, when the driving wheel 140 rotates, the driving gear belt linearly moves by the meshing transmission between the teeth, so that the length of the gear belt between the sound attachment bracket 150 and the driving wheel 140 is increased or shortened, and the sound attachment bracket 150 reciprocates along the rail assembly, thereby implementing the extension or retraction of the sound 30.

Further, in some embodiments, the flat display device further includes a slide rail 180 for being mounted on the body 20 of the flat display device, and the gear belt moves linearly along the slide rail 180. As shown in fig. 11 and 12, the slide rail 180 is provided at a position between the driving wheel 140 and the audio connection bracket 150. The length of slide rail 180 should not affect the up and down movement of audio interface bracket 150. The sliding rail 180 may also be fixed on the display module 210.

An embodiment of the present invention further provides a flat panel display device, which includes a body 20 and the sound expansion structure 10 of any of the foregoing embodiments, wherein the sound 30 is connected to the sound connection bracket 150, and the sound expansion structure 10 can drive the sound 30 to extend out of and retract into the body 20.

As shown in fig. 1 and 4, when the sound equipment retractable structure 10 can drive the sound equipment 30 to retract into the main body 20, the front of the flat display device can achieve the visual effect of a full screen or a narrow frame. As shown in fig. 3 and 5, when the acoustic telescopic structure 10 extends the acoustic 30 to the display ground side, a preferable sound effect is achieved.

Similar to the previous embodiments, in this embodiment, the rail assembly includes a rail 172. The guide rails 172 are provided in pairs. Each guide rail 172 may be configured as shown in fig. 6, that is, include a first guide section 1721, a second guide section 1722 and an arc-shaped guide section 1723, so that the sound box 30 can move vertically downward and then move horizontally forward to a position flush with the screen 230 of the flat display device, thereby achieving a better sound output effect.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
