Example one

The embodiment one provides a display device with a position-variable sound-emitting unit.

Referring to fig. 1-5, the display device 1000 includes a driving structure capable of outputting a reciprocating motion along at least one direction, and at least having a receiving position and an extending position on a moving stroke of the driving structure, the sound generating unit 200 is mounted on the driving structure, when the driving structure is in the receiving position, the sound generating unit 200 is received in the display device 1000, and when the driving structure is in the extending position, the sound generating unit 200 extends from an edge of the display device 1000 and is in the same orientation or approximately in the same orientation as a display surface of the display device 1000.

In this way, due to the arrangement of the driving structure, when the driving structure moves to the accommodating position, the sound generating unit 200 is accommodated in the display device 1000, and at this time, namely, in the power-off state, the sound generating unit 200 cannot be noticed from the front of the display surface of the display device 1000, so that the display device 1000 has an excellent aesthetic effect when being powered off; when the driving structure moves to the extended position, the sound generating unit 200 extends from the edge of the display device 1000 and is oriented in the same direction as the display surface of the display device 1000, and the sound generating direction of the sound generating unit 200 is oriented to the user in front of the display surface in the power-on state, so that the display device 1000 has excellent audio and visual feeling when being powered on.

The specific kind of the display apparatus 1000 according to the embodiment of the present invention is not limited. According to some embodiments of the invention, the display apparatus 1000 may be a liquid crystal television, a plasma television, an OLED television, a simple display, or the like.

On the other hand, according to the embodiment of the present invention, the specific kind of the pronunciation unit 200 is not limited. According to some embodiments of the invention, the sound unit 200 may be a horn sound cavity.

Further, the display surface of the display apparatus 1000 indicated in the foregoing refers to the front surface of the display apparatus 1000 used to display an image.

Further, for convenience of description and for understanding of the context, the following description will be made by taking an lcd tv as an example, and it is understood that the settings or designs made on the lcd tv can also be applied to other display devices 1000. Meanwhile, for convenience of description, a horn sound cavity will be described as an example of the sound generation unit 200, or the sound generation unit 200 referred to hereinafter may be understood as a horn sound cavity.

The lcd tv is preferably an integrated tv, and in this case, the integrated tv may include a driving structure, a display 300, a back plate 400, a rear case 500, a leg 600, and the like.

The display screen 300 is used for displaying images, and the display screen 300 is preferably configured as a full-screen, but may be other types of screens. The back plate 400 and the rear case 500 are disposed on the back of the display 300, and mainly perform heat dissipation and installation functions, such as installing a driving structure and accommodating the sound generating unit 200. A foot 600 or the like is provided at the bottom of the display screen 300 for supporting.

In the embodiment of the present invention, in order to facilitate the housing of the sound generation unit 200, a cavity 1100 having a size specification matching the sound generation unit 200 may be provided in the display device 1000, for example, when the sound generation unit 200 employs a horn cavity, the cavity 1100 may be configured as a rectangular parallelepiped cavity. Thus, when the driving structure is in the accommodating position, the sound generating unit 200 can be accommodated in the cavity 1100, which is beneficial to saving the space of the display device 1000 and improving the stability of the sound generating unit 200 in the cavity 1100.

In the embodiment of the present invention, referring to fig. 2 to 3, the cavity 1100 is disposed on the back of the display apparatus 1000, which mainly matches the structure and general usage state of the display apparatus 1000, when the display apparatus 1000 is used, the back of the display apparatus is generally invisible, and the space on the back of the display apparatus is generally large, so that the cavity 1100 is disposed on the back of the display apparatus 1000, which can have a large design space and does not affect the appearance of the whole display apparatus 1000.

Further, the cavity 1100 is formed by enclosing the back plate 400 and the rear case 500 of the display device 1000, and the opening direction of the cavity 1100 faces to the lower side, so that the sound generating unit 200 can be accommodated in the cavity 1100 or extend out of the cavity 1100 only by outputting the reciprocating motion along the vertical direction by the driving structure.

Of course, the opening direction of the cavity 1100 may be oriented in other directions, such as left or right, as described in detail in example nine below.

When the opening direction of the cavity 1100 is directed to the lower side, the driving structure may include a first driving mechanism 100, the first driving mechanism 100 outputs a reciprocating motion in the vertical direction, and the sound generation unit 200 is installed at the output end of the first driving mechanism 100.

Further, the first driving mechanism 100 includes a first driving member 110 and a vertical moving assembly 120, the first driving member 110 is used for driving the vertical moving assembly 120 to reciprocate vertically, and the sound generating unit 200 is mounted on the vertical moving assembly 120.

In this way, the vertical moving component 120 can reciprocate vertically by the driving action of the first driving element 110, and the sound unit 200 can be accommodated in the cavity 1100 or extend out of the cavity 1100 during the reciprocating motion.

Specifically, referring to fig. 2-5, when the integrated tv is turned off, the sound generating unit 200 is located in the cavity 1100, and when the integrated tv is turned on, the first driving mechanism 100 is activated and drives the sound generating unit 200 to extend downward from the cavity 1100, and at this time, the sound generating unit 200 is located right below the cavity 1100.

In some embodiments, the driving mechanism may further include a second driving mechanism (not shown) in addition to the first driving mechanism 100 described above, the second driving mechanism outputting a reciprocating motion in a horizontal direction, and the first driving mechanism 100 is mounted on the second driving mechanism and driven by the second driving mechanism to perform the reciprocating motion in the horizontal direction.

Further, the second driving mechanism includes a second driving member and a horizontal moving assembly, the second driving member is used for driving the horizontal moving assembly to realize reciprocating motion in the horizontal direction, and the first driving mechanism 100 is installed on the horizontal moving assembly.

Up to this point, the first driving mechanism 100 and the second driving mechanism are combined to move the sound unit 200 in both vertical and horizontal directions.

Specifically, referring to fig. 6 to 7, after the sound generating unit 200 is located right below the cavity 1100, by activating the second driving mechanism, the entire first driving mechanism 100 can be driven to move towards the display surface of the integrated television, so that the sound generating unit 200 can be located right below the display surface, and at this time, the sound generating unit is closer to the user, which can further improve the audio visual perception of the user.

In order to achieve precise control of the first and second driving mechanisms 100 and to regulate the movement path of the sound unit 200, a first limit position may be set for the first driving mechanism 100, the first limit position being defined to allow the sound unit 200 to be just fully extended from the cavity 1100. And a second limit position is set for the second driving mechanism with respect to moving the sound emitting unit 200 just under the display surface. The first limit position and the second limit position can be realized by the proximity switch in the following embodiments, that is, when the integrated tv is turned on, the first driving mechanism 100 is started and drives the sound generating unit 200 to the first limit position, as shown in fig. 4-5, the proximity switch is activated to stop the first driving mechanism 100, then the second driving mechanism drives the sound generating unit 200 to the second limit position, as shown in fig. 6-7, the proximity switch is activated again to stop the second driving mechanism, and finally the sound generating unit 200 stays at the second limit position. When the device is turned off, the second driving mechanism is first started, and then the first driving mechanism 100 is started, so that the sound generating unit 200 is finally accommodated in the cavity 1100, as shown in fig. 1 to 3.

Referring to fig. 8-11, in the embodiment of the invention, the first driving member 110 of the first driving mechanism 100 is a driving motor, and the vertical moving assembly 120 includes a lifting rope 121 and a lifting rod 122.

The driving motor is used for providing power, the lifting rope 121 is sleeved on an output shaft of the driving motor, lifting motion is realized along with rotation of the output shaft, the lifting rod 122 is vertically arranged, one end of the lifting rod is connected to the tail end of the lifting rope 121, and the other end of the lifting rod is connected to the sound generating unit 200.

Like this, can realize the lift of lifting rope 121 through the start-up of control driving motor and control driving motor's positive and negative commentaries on classics, drive lifter 122 lift then, finally make pronunciation unit 200 realize vertical reciprocating motion, just also realized pronunciation unit 200 and acceptd in cavity 1100, perhaps stretch out from cavity 1100.

In some embodiments, the vertical movement assembly 120 may further include at least one pulley 123, the lift cord 121 being looped over the pulley 123, such as in the example shown in fig. 8, for a total of two pulleys 123. Of course, more pulleys 123 may be provided in other examples.

Through the arrangement of the pulley 123, the arrangement direction of the driving motor can be changed, so that the lifting rope 121 can be positioned above the lifting rod 122 by bypassing the pulley 123, which is beneficial to the layout of the driving motor and the lifting rope 121 and is beneficial to saving space.

Further, in order to regulate the lifting path of the lifting rod 122 and prevent the lifting rod 122 from deviating, the vertical moving assembly 120 may further include a vertically arranged slide rail 124 and a slider 125 slidably disposed on the slide rail 124, and the lifting rod 122 is connected to the slider 125.

Therefore, the sliding block 125 can only move on the sliding rail 124, and after the lifting rod 122 is connected to the sliding block 125, it is ensured that the lifting rod 122 can only move along the vertically arranged sliding rail 124.

In some embodiments, the vertical moving assembly 120 may further include a limiting assembly 126, and the limiting assembly 126 is disposed at the upper and lower ends of the sliding rail 124 for limiting the limit position of the sliding block 125.

Thus, the sound unit 200 can be moved to the first limit position by the positioning of the limiting component 126.

Specifically, the limiting assembly 126 includes limiting baffles 1261 disposed at the upper and lower ends of the slide rail 124, the limiting baffles 1261 can limit the up-and-down movement of the lifting rod 122 within the stroke formed by the two limiting baffles 1261, when the lifting rod moves to the upper limiting baffle 1261, the sound generating unit 200 is accommodated in the cavity 1100, as shown in fig. 8, and when the lifting rod moves to the lower limiting baffle 1261, the sound generating unit 200 is at the first limit position, as shown in fig. 10.

Further, an elastic buffer portion 1261a is further provided at a middle position of the limit stopper 1261, so that the slider 125 and/or the lift lever 122 is elastically contacted with the limit stopper 1261.

Thus, the switching process of the sound unit 200 between the cavity 1100 and the first limit position can be performed more smoothly and stably by the buffering action of the elastic buffering portion 1261a, and the shaking or noise generation caused by the excessive impact force can be avoided. In addition, the arrangement of the elastic buffer part 1261a is also beneficial to avoiding the influence of rigid contact on the service life of the limit baffle 1261 and the lifting rod 122.

In some embodiments, the elastic buffering portion 1261a may be made of rubber, silicon, or other materials.

As previously described, a proximity switch (not shown) may be provided at the limit stop 1261 to indicate the limit position of the slide 125 for directing the first drive mechanism 100 to start and stop.

Specifically, when the integrated television is in a power-off state, the slider 125 is located at the position of the upper limit baffle 1261, and when the integrated television is powered on, the driving motor receives a power-on signal, so that the integrated television starts to rotate, a certain distance is released through the transmission of the pulley 123 and the lifting rope 121, the lifting rod 122 and the sound generating unit 200 move downward under the gravity of the lifting rod and the sound generating unit until the integrated television moves to the position of the lower limit baffle 1261, at this time, the driving motor stops rotating, and the sound generating unit 200 is located at the first limit position. When the integrated tv is turned off again, the driving motor rotates reversely for the same number of revolutions, so that the sound generating unit 200 is accommodated in the cavity 1100 again.

In the embodiment of the present invention, two sets of driving motors and vertical moving assemblies 120 are provided and are respectively located at two ends of the sound generating unit 200, so that the sound generating unit 200 can be ensured to perform stable vertical movement.

Of course, in other embodiments, a combination of more sets of driving motors and the vertical moving assembly 120 may be provided to further improve the above-mentioned stabilizing effect.

In addition, in some embodiments, in order to further improve the stable movement of the sound unit 200, the vertical movement assembly 120 may further include a transverse transition rod 127, the transverse transition rod 127 is horizontally disposed, the other end of the lifting rod 122 is connected to the transverse transition rod 127, and the sound unit 200 is connected to the transverse transition rod 127.

Thus, by the arrangement of the transverse transition rod 127, the contact area between the sound unit 200 and the transverse transition rod 127 can be increased, so as to improve the stability of the sound unit 200 during vertical movement.

In the embodiment provided with the second driving mechanism, the second driving part of the second driving mechanism may also adopt a driving motor, or a telescopic cylinder, etc., the vertical moving assembly 120 may include a plate body mounted on the driving motor or the telescopic cylinder, and the first driving mechanism 100 is integrally mounted on the plate body, and the plate body may move towards the display surface of the integrated television under the driving of the driving motor or the telescopic cylinder, so that the sound generating unit 200 moves from the first limit position to the second limit position.

In embodiments where the second driving mechanism is not provided, the first driving mechanism 100 may be mounted on the back plate 400 of the integrated tv.

Example two

The second embodiment provides a first driving mechanism 100.

Referring to fig. 12 to 13, the structure and principle of the first driving mechanism 100 of the second embodiment are substantially the same as those of the first driving mechanism 100 of the first embodiment, except that in the present embodiment, the driving motor and the vertical moving component 120 are disposed at the middle position of the sound generating unit 200, and the two ends of the sound generating unit 200 are further provided with guide rods 700, and the guide rods 700 are sleeved in the limiting blocking pieces 800.

Thus, when the first driving mechanism 100 works, the guide rods 700 at the two ends of the sound generation unit 200 are matched with the limiting blocking pieces 800, so that the stability of the vertical movement of the sound generation unit 200 can be ensured.

Of course, as described in the first embodiment, in the second embodiment, a combination of more sets of driving motors and the vertical moving assembly 120 may also be provided to further improve the above-mentioned stabilizing effect.

In addition, similar to the first embodiment, a transverse transition rod 127 may be disposed between the sound unit 200 and the lifting rod 122 and the guide rod 700.

EXAMPLE III

The third embodiment provides a first driving mechanism 100.

Referring to fig. 14-15, the first driving member 110 of the first driving mechanism 100 is a driving motor, and the vertical moving assembly 120 includes a lifting rope 121, a lifting rod 122 and a guiding and limiting assembly 128.

The driving motor is used for providing power, the lifting rope 121 is sleeved on an output shaft of the driving motor, and lifting movement is achieved along with rotation of the output shaft. The elevation rod 122 is horizontally disposed, and the sound-generating unit 200 is installed on the elevation rod 122. The guide limit assembly 128 is connected to the lifting rod 122 for guiding and limiting the lifting rod 122, and at least one of the guide limit assembly 128 and the lifting rod 122 is connected to the lifting rope 121.

Therefore, the lifting of the lifting rope 121 can be realized by controlling whether the driving motor is started or not and controlling the forward and reverse rotation of the driving motor, and then the lifting rod 122 or the guide limiting assembly 128 is driven to lift, so that the pronunciation unit 200 finally realizes vertical reciprocating motion, and the pronunciation unit 200 is accommodated in the cavity 1100 or stretches out of the cavity 1100. In the lifting process, the stability of the vertical movement of the pronunciation unit 200 can be ensured due to the action of the guide limit component 128.

As in the first embodiment, the vertical moving assembly 120 may further include at least one pulley 123, and the lifting rope 121 is fitted over the pulley 123, for example, in the example shown in fig. 14, two pulleys 123 are provided in total. Of course, more pulleys 123 may be provided in other examples.

In this embodiment, the guiding and limiting members 128 are two sets and are respectively disposed at two ends of the lifting rod 122. Meanwhile, two sets of driving motors, the lifting ropes 121 and the pulleys 123 are also provided, and are respectively provided at both ends of the lifting rod 122.

Of course, in other embodiments, more sets of drive motors, lift cords 121, and pulleys 123 may be provided.

With continued reference to fig. 14, the guiding and limiting assembly 128 includes a vertically arranged guide rail 1281, a guide block 1282 slidably disposed on the guide rail 1281, and a mounting frame 1283 connected to the guide block 1282, wherein the lifting rod 122 is mounted on the mounting frame 1283.

In the third embodiment, the end of the lifting rope 121 is connected to the lifting rod 122, and the driving action of the driving motor can make the lifting rod 122 perform lifting movement, and finally make the sound unit 200 perform vertical movement. In the lifting process of the lifting rod 122, because the lifting rod 122 is connected with the mounting frame 1283, the mounting frame 1283 is dragged by the guide block 1282, and the guide block 1282 is limited by the guide rail 1281, the lifting rod 122 is limited to only do lifting movement, and the stability of the vertical movement of the pronunciation unit 200 is ensured.
