The first embodiment is as follows:

referring to fig. 1 and 2, an embodiment of the invention provides a multifunctional conference all-in-one machine, which includes a case 1, wherein a display screen extension port 11 and a microphone extension port 12 are respectively formed at an upper end of the case 1, a display screen flip 2 is arranged on the display screen extension port 11, and a microphone flip 3 is arranged on the microphone extension port 12. The multifunctional conference all-in-one machine of the embodiment further comprises a display screen automatic extending and retracting device 4 and a microphone automatic extending and retracting device 5 which are respectively arranged in the case 1, wherein the display screen automatic extending and retracting device 4 comprises a display screen automatic lifting mechanism 41 arranged in the case 1, a display screen 42 arranged on the display screen automatic lifting mechanism 41 and capable of extending from the display screen extending port 11, and at least one display screen flip automatic opening and closing mechanism 43 arranged in the case 1 and connected to the display screen flip 2. The automatic microphone extending and retracting device 5 comprises an automatic microphone lifting mechanism 51 arranged in the case 1, a microphone 52 arranged on the automatic microphone lifting mechanism 51 and capable of extending from the microphone extending port 12, and at least one automatic microphone flip opening and closing mechanism 53 connected to the microphone flip 3.

The display screen 42 can be driven by the automatic display screen lifting mechanism 41 to do lifting movement, and the automatic display screen flip cover opening and closing mechanism 43 controls the opening and closing of the display screen flip cover 2, so that the display screen 42 can extend out of the display screen extension opening 11 for use and can be automatically retracted after use; meanwhile, the microphone 52 can be driven by the automatic microphone lifting mechanism 51 to do lifting movement, and the opening and closing of the microphone flip 3 is controlled by the automatic microphone flip opening and closing mechanism 53, so that the microphone 52 can be extended from the microphone extension port 12 for use, and can be automatically retracted after use.

In this embodiment, as shown in fig. 3, the automatic opening and closing mechanism 43 for the display screen flip cover includes a first fixing seat 431 disposed at the lower portion of the inner side of the chassis 1, a first pull rod 432 rotatably connected to the display screen flip cover 2, a first positioning sliding member 433 slidably disposed on the first fixing seat 431 and connected to the first pull rod 432, an upper pushing block 434 formed on the display screen lifting bracket 410 of the automatic display screen lifting mechanism 41, a returning pushing block 435 rotatably disposed on the upper pushing block 434 and located above the first positioning sliding member 433, and a first buffer spring 436 connected between the returning pushing block 435 and the upper pushing block 434, wherein a first longitudinal sliding hole 4311 for sliding the first positioning sliding member 433 is formed on the first fixing seat 431, the first longitudinal sliding hole 4311 mainly includes a first vertical sliding hole 43111 and a first oblique sliding hole 43112 formed by bending the upper portion of the first vertical sliding hole 43111 inward, as shown in fig. 4.

Specifically, the bent portion of the first vertical sliding hole 43111 and the first inclined sliding hole 43112 is a smooth arc-shaped structure, so that the first positioning sliding element 433 can smoothly move between the first vertical sliding hole 43111 and the first inclined sliding hole 43112.

Due to the special structural design of the combination of the first longitudinal sliding hole 4311 and the first positioning sliding member 433, not only can a guiding function be provided for the up-and-down movement of the first pull rod 432, but also the up-and-down movement range of the first pull rod 432 can be limited, so as to ensure that the opening and closing movement strokes of the display screen flip 2 are the same each time.

Specifically, as shown in fig. 5, the end of the upper pushing block 434 has an upper hook 4340. In the process that the display screen lifting bracket 410 drives the upper pushing block 434 to move upwards, the upper hook portion 4340 applies an upward acting force to the first positioning sliding member 433, so that the first positioning sliding member 433 moves upwards in the first vertical sliding hole 43111 until the first positioning sliding member 433 slides into the first inclined sliding hole 43112; then, the upper hook portion 4340 is separated from the first positioning slider 433, and the upper push block 434 continues to move upward.

Specifically, as shown in fig. 5, a lower hook 4350 is provided at the end of the reset push block 435. In the process that the display screen lifting support 410 drives the reset push block 435 to move downwards, the lower hook portion 4350 acts on the first positioning sliding member 433 downwards, so that the first positioning sliding member 433 slides out of the first oblique sliding hole 43112 along the oblique inner wall of the first oblique sliding hole 43112 until entering the first vertical sliding hole 43111; then, as the reset pushing block 435 moves downward, the first positioning sliding member 433 is driven to move downward in the first vertical sliding hole 43111.

Specifically, as shown in fig. 6, an upper connecting shaft 4351 is disposed on the reset push block 435, a lower connecting shaft 4101 is disposed on the upper push block 434, and the first buffer spring 436 is connected between the upper connecting shaft 4351 and the lower connecting shaft 4101. For the effect of the first buffer spring 436, in the process of closing the display screen flip cover 2 onto the display screen extension opening 11, due to the existence of the first buffer spring 436, when the reset push block 435 applies a downward acting force to the first positioning slide 433, an upward reaction force exists on the reset push block 435 by the first positioning slide 433, so that the reset push block 435 rotates, and the first buffer spring 436 is elastically deformed, and then the first buffer spring 436 plays a role of buffering and preventing hands from being pinched. Specifically, after the display screen 42 is driven by the display screen automatic lifting mechanism 41 to descend and be accommodated in the case 1, the display screen flip 2 needs to be closed; therefore, the first pull rod 432 drives the display screen flip cover 2 to swing towards the display screen extension opening 11, and at this time, if a hand is placed in the display screen extension opening 11, if the first buffer spring 436 does not exist, the swing closing action of the display screen flip cover 2 applies a large acting force to the hand, a hand clamping phenomenon occurs, and the hand is seriously injured. Due to the existence of the first buffer spring 436 in the embodiment, a good buffering effect is achieved, the acting force when the display screen flip cover 2 touches a human hand is weakened, the time when the display screen flip cover 2 touches the human hand is slowed down, and therefore the injury degree of the human hand is reduced.

Specifically, the first positioning slider 433 may be a screw or a bolt.

In order to further play a role of buffering and preventing hands from being clamped, a second buffer spring 437 is connected between the inner wall of the case 1 and the first pull rod 432 in the embodiment. In the process that first pull rod 432 reciprocated, elastic deformation takes place for second buffer spring 437, provides the cushioning effect by second buffer spring 437, prevents that first pull rod 432 atress from removing at the excessive speed, plays the purpose that the tong was prevented in the buffering.

In order to facilitate the first pull rod 432 to smoothly open and close the display screen flip 2, in this embodiment, two ends of the display screen flip 2 are respectively rotatably disposed on the inner wall of the chassis 1 through a connecting plate 21, and the upper end of the first pull rod 432 is rotatably connected to the connecting plate 21. Because the first pull rod 432, the connecting plate 21 and the display screen flip cover 2 are adaptively rotated, the display screen flip cover 2 can be opened and closed smoothly by the first pull rod 432. Therefore, the number of the display screen flip automatic opening and closing mechanisms 43 in this embodiment is two, and the two mechanisms are respectively connected to the connecting plates 21 at the two ends of the display screen flip 2.

When the display screen flip 2 needs to be opened, so that the display screen 42 can be extended out from the display screen extension port 11 for use, the display screen automatic lifting mechanism 41 drives the display screen lifting support 410 to move upward, and then the display screen lifting support 410 drives the upper push block 434 to move upward, and the upper hook portion 4340 of the upper push block 434 applies an upward acting force to the first positioning slider 433, as shown in fig. 7 and 8, so that the first positioning slider 433 moves upward in the first vertical sliding hole 43111 until the first positioning slider 433 slides into the first oblique sliding hole 43112, that is, the first positioning slider 433 is limited in the first oblique sliding hole 43112, as shown in fig. 9 and 10; in the process, the first pull rod 432 moves upwards, so that the first pull rod 432, the connecting plate 21 and the display screen flip cover 2 rotate adaptively, the display screen flip cover 2 is driven to move away from the display screen extension opening 11, and the display screen extension opening 11 is completely opened; then, as the first positioning sliding member 433 slides into the first inclined sliding hole 43112, the upper hook portion 4340 of the upper pushing block 434 is separated from the first positioning sliding member 433, and the display screen lifting bracket 410 continues to move upward, and finally drives the display screen 42 to extend out of the display screen extension opening 11 for use.

When the display screen 42 needs to be retracted into the chassis 1 after being used, the automatic display screen lifting mechanism 41 drives the display screen lifting bracket 410 and the display screen 42 to move downward until the lower hook portion 4350 of the reset push block 435 on the display screen lifting bracket 410 moves downward to contact with the first positioning sliding member 433, and the lower hook portion 4350 acts downward on the first positioning sliding member 433, so that the first positioning sliding member 433 slides out of the first oblique sliding hole 43112 along the oblique inner wall of the first oblique sliding hole 43112 until entering the first vertical sliding hole 43111, that is, the states of fig. 9 and 10 are changed into the states of fig. 7 and 8; then, with the downward movement of the reset push block 435, the first positioning slider 433 is driven to move downward in the first vertical sliding hole 43111; in the process that the first positioning sliding member 433 moves down, the display screen 42 is completely retracted into the chassis 1, and meanwhile, as the first pull rod 432 moves down, the first pull rod 432 pulls the connecting plate 21 downward, so that the first pull rod 432, the connecting plate 21 and the display screen flip cover 2 rotate adaptively, and the display screen flip cover 2 is driven to move to the display screen extension opening 11 to cover the display screen extension opening 11, as shown in fig. 3 and 4, the retraction of the display screen 42 is completed.

In this embodiment, as shown in fig. 11, the automatic display screen lifting mechanism 41 includes a display screen lifting rack 411 and at least one lifting guide rod 412 vertically disposed in the chassis 1, a display screen lifting support 410 disposed in the chassis 1 and slidably disposed on the lifting guide rod 412, a display screen lifting driving motor 413 disposed in the chassis 1 and connected to the display screen lifting support 410, and a display screen lifting transmission gear 414 disposed on an output shaft of the display screen lifting driving motor 413 and engaged with the display screen lifting rack 411, wherein the display screen 42 is disposed on the display screen lifting support 410. The display screen lifting driving motor 413 provides driving force to drive the display screen lifting transmission gear 414 to rotate, and since the display screen lifting rack 411 is fixed in the case 1, when the display screen lifting transmission gear 414 rotates, the display screen lifting transmission gear must move up and down along the display screen lifting rack 411, so as to drive the display screen lifting support 410 and the display screen 42 to do lifting movement. For example, when the screen lifting transmission gear 414 rotates clockwise, the screen lifting bracket 410 and the screen 42 move up, and vice versa, the screen lifting bracket 410 and the screen 42 move down.

In this embodiment, the display screen lifting rack 411 is engaged with the display screen lifting transmission gear 414, so that the lifting movement is realized, the noise is low, the operation is stable and stable, and the service life is long.

Example two:

the main difference between the first embodiment and the second embodiment is that, as shown in fig. 11 and 12, two ends of the display screen lifting bracket 410 are respectively provided with a display screen automatic swing angle assembly 416, specifically, the display screen automatic swing angle assembly 416 includes a swing angle linkage plate 4161 rotatably disposed at an end of the display screen lifting bracket 410, and at least one first return spring 4162 connected between the swing angle linkage plate 4161 and a side edge of the display screen lifting bracket 410, and the display screen 42 is disposed on the swing angle linkage plate 4161 at two ends of the display screen lifting bracket 410; meanwhile, a swing ejecting piece 4162 for ejecting the lower part of the swing angle linkage plate 4161 is arranged on the inner wall of the case 1.

In the process that the display screen lifting bracket 410 rises, the swing angle linkage plate 4161 rises along with the rise, and when the swing angle linkage plate 4161 does not rise to the side edge of the swing ejecting piece 4162, the swing angle linkage plate 4161 drives the display screen 42 to rise vertically along with the display screen lifting bracket 410 and extend out of the display screen extension opening 11; when the swing angle linkage plate 4161 rises to the front side of the swing angle linkage plate 4162, as shown in fig. 12, the swing angle linkage plate 4162 contacts with the lower portion of the swing angle linkage plate 4161, and as the swing angle linkage plate 4161 continues to rise, the swing angle linkage plate 4161 is pushed outward by the swing angle linkage member 4162, so that the upper portion of the swing angle linkage plate 4161 swings inward by a certain angle, and the display screen 42 is driven to swing by a corresponding angle, so as to achieve the purpose of tilting the display screen 42, as shown in fig. 13 and 14, a user can conveniently view the content displayed on the display screen 42, and at this time, the first return spring 4162 deforms. In the process that the swing angle linkage plate 4161 drives the display screen 42 to descend along with the display screen lifting support 410 and retract into the case 1, the swing angle linkage plate 4161 continuously descends, when the lower part of the swing angle linkage plate 4161 gradually disengages from the swing ejecting piece 4162, the swing ejecting piece 4162 releases acting force on the lower part of the swing angle linkage plate 4161, under the action of elastic restoring force of the first restoring spring 4162, the swing ejecting piece 4162 drives the display screen 42 to reversely swing and reset, and finally vertically descends and retracts into the case 1.

Specifically, the upper part of the swing angle linkage plate 4161 is rotatably disposed on the display screen lifting bracket 410, a transverse sliding hole 41611 is formed at the lower part of the swing angle linkage plate 4161, and a sliding shaft 4101 inserted into the transverse sliding hole 41611 is disposed on the side edge of the display screen lifting bracket 410; meanwhile, a protrusion 41610 facing the swing ejecting member 4162 is protruded at the lower portion of the swing angle interlocking plate 4161. Meanwhile, an installation block 417 is arranged upwards at the end of the display screen lifting bracket 410, and the upper part of the swing angle linkage plate 4161 is rotatably connected with the installation block 417 through a bolt 418.

When the swing angle linkage plate 4161 rises to the positive side of the swing ejecting member 4162, the swing ejecting member 4162 contacts the protrusion 41610 of the swing angle linkage plate 4161 and the protrusion 41610 is pushed outward by the swing ejecting member 4162, and the transverse sliding hole 41611 of the swing angle linkage plate 4161 slides along the sliding shaft 4101 with the bolt 418 at the upper part of the swing angle linkage plate 4161 as the center point, thereby swinging a certain angle, as shown in fig. 14. The transverse sliding hole 41611 is combined with the sliding shaft 4101 to limit the swinging path and angle of the swinging angle linkage plate 4161, so that the stability and accuracy of the swinging angle linkage plate 4161 during swinging are improved, and the phenomenon of disordered swinging is avoided.

Specifically, one end of the first return spring 4162 is connected to the upper portion of the swing angle linkage plate 4161, and the other end is connected to the lower portion of the side edge of the display screen lifting bracket 410. In the process that the swing angle linkage plate 4161 swings with the bolt 418 at the upper part as the central point, the upper part of the swing angle linkage plate 4161 drives the display screen 42 to swing at a corresponding angle, and the first return spring 4162 is stretched to generate corresponding deformation, and after the acting force for promoting the swing action to disappear, the first return spring 4162 provides restoring acting force for resetting.

Specifically, the swinging ejecting member 4162 is mainly composed of a bearing seat 41621 disposed on the inner wall of the chassis 1, and at least one bearing 41622 rotatably disposed on the bearing seat 41621. When the oscillating angle linkage plate 4161 rises to the lower part and the protrusion 41610 contacts with the lower edge of the bearing 41622, the oscillating angle linkage plate 4161 continues to rise, the protrusion 41610 and the bearing 41622 generate a relative force, the protrusion 41610 drives the bearing 41622 to rotate until the oscillating angle linkage plate 4161 rises to the positive side of the protrusion 41610, and in the process, the bearing 41622 pushes the protrusion 41610 outwards to enable the oscillating angle linkage plate 4161 to rotate. Therefore, the rotation of the rotatable bearing 41622 provides an auxiliary function for the lifting of the swing angle linkage plate 4161, and prevents the excessive resistance from affecting the continuous lifting of the swing angle linkage plate 4161 when the protrusion 41610 is just in contact with the bearing 41622.

Example three:

the main difference between the present embodiment and the first or second embodiment is that, as shown in fig. 15 and fig. 16, the microphone flip automatic opening and closing mechanism 53 includes a second fixed seat 531 disposed at the lower portion of the inner side of the chassis 1, a second pull rod 532 rotatably connected to the microphone flip 3, a second positioning sliding member 533 slidably disposed on the second fixed seat 531 and connected to the second pull rod 532, a pushing member 534 connected to the microphone lifting bracket 510 of the microphone automatic lifting mechanism 51 and acting on the second positioning sliding member 533, an upper pushing block 535 slidably disposed on the second fixed seat 531 and located below the second positioning sliding member 533, and a third buffer spring 536 connected between the upper pushing block 535 and the inner side of the chassis 1, wherein a second longitudinal sliding hole 5311 for the second positioning sliding member 533 to slide is formed on the second fixed seat 531, and the second longitudinal sliding hole 5311 mainly consists of a second vertical sliding hole 53111, a vertical sliding hole sliding, And a second inclined sliding hole 53112 formed by bending the upper portion of the second vertical sliding hole 53111 toward the inner side of the chassis 1, as shown in fig. 18.

Specifically, the bent portions of the second vertical sliding hole 53111 and the second inclined sliding hole 53112 are smooth arc-shaped structures, so that the second positioning sliding member 533 can smoothly move between the second vertical sliding hole 53111 and the second inclined sliding hole 53112.

Due to the special structural design of the combination of the second longitudinal sliding hole 5311 and the second positioning sliding member 533, not only a guiding function can be provided for the up-and-down movement of the second pull rod 532, but also the up-and-down movement range of the second pull rod 532 can be limited, so as to ensure that the opening and closing strokes of the microphone flip 3 are the same each time.

Specifically, as shown in fig. 19, an opening 5340 is formed on the pushing member 534, an upper hook 5341 is formed at an upper portion of the opening 5340, and in the process that the microphone lifting bracket 510 drives the pushing member 534 to move downward, the upper hook 5341 acts downward on the second positioning slider 533, so that the second positioning slider 533 slides out of the second inclined sliding hole 53112 along the inclined inner wall of the second inclined sliding hole 53112 until entering the second vertical sliding hole 53111; then, as the pushing member 534 moves downward, the second positioning sliding member 533 is driven to move downward in the second vertical sliding hole 53111. Meanwhile, an upper guiding inclined plane 53411 is formed at the inner side edge of the upper hook 5341, and the upper guiding inclined plane 53411 is inclined from the top to the bottom towards the inner side of the case 1. Due to the special design of the upper guiding inclined plane 53411, in the downward moving process of the pushing member 534, the second positioning sliding member 533 slides outward under the guiding action of the upper guiding inclined plane 53411 of the upper hook 5341, thereby sliding out of the second inclined sliding hole 53112 and entering the second vertical sliding hole 53111. Therefore, the second positioning sliding member 533 can slide out of the second oblique sliding hole 53112 and enter the second vertical sliding hole 53111 smoothly, and the sliding stability of the second positioning sliding member 533 is improved.

Meanwhile, as shown in fig. 19, a lower hook 5342 is formed at the lower portion of the opening 5340, and in the process that the microphone lifting bracket 510 drives the pushing member 534 to move upwards, the lower hook 5342 acts on the second positioning sliding member 533 upwards, so that the second positioning sliding member 533 moves vertically upwards along the second vertical sliding hole 53111 until entering the second inclined sliding hole 53112, so that the second positioning sliding member 533 is limited in the second inclined sliding hole 53112. Meanwhile, a lower guiding inclined plane 53421 is formed at the inner side of the lower hook 5342, and the lower guiding inclined plane 53421 is inclined from the top to the bottom toward the inner side of the case. Due to the special design of the lower guiding inclined surface 53421, when the pushing member 534 pushes the second positioning sliding member 533 to move upward to the connection position of the second vertical sliding hole 53111 and the second inclined sliding hole 53112, the second positioning sliding member 533 slides toward the second inclined sliding hole 53112 under the guiding action of the lower guiding inclined surface 53421 of the lower hook 5342, and thus slides into the second inclined sliding hole 53112. Therefore, the second positioning sliding member 533 can smoothly slide into the second inclined sliding hole 53112 from the second vertical sliding hole 53111, and the sliding stability of the second positioning sliding member 533 is improved.

Specifically, as shown in fig. 16, a limiting guide inclined plane 5350 is formed on the upper end surface of the push-up block 535, and the limiting guide inclined plane 5350 is inclined from top to bottom toward the inside of the chassis. Due to the arrangement of the limiting guide inclined plane 5350, the second positioning sliding piece 533 sliding into the second inclined sliding hole 53112 is limited, and the second positioning sliding piece 533 is prevented from sliding out.

As for the combination manner of the pushing-up block 535 and the second fixing seat 531, as shown in fig. 16, in this embodiment, a third longitudinal sliding hole 5351 is formed on the pushing-up block 535, and at least one positioning member 5312 is disposed on the second fixing seat 531, preferably, the number of the positioning members 5312 is two, and the positioning members 5312 are embedded in the third longitudinal sliding hole 5351. Therefore, under the matching action of the positioning member 5312 and the third longitudinal sliding hole 5351, the push-up block 535 can vertically slide on the second fixing seat 531 along the positioning member 5312.

Specifically, as shown in fig. 17, a connecting member 5352 is disposed on the push-up block 535, and the third buffer spring 536 is connected between the connecting member 5352 and the second fixing seat 531. Therefore, when the push-up block 535 slides up and down along the second fixing seat 531, the third buffer spring 536 can provide elastic restoring force.

Meanwhile, with respect to the function of the third buffer spring 536, in the process of closing the microphone flip 3 onto the microphone extension opening 12, due to the existence of the third buffer spring 536, when the pushing member 534 applies a downward acting force to the second positioning sliding member 533, the pushing-up block 535 is simultaneously applied with a downward acting force, so that the third buffer spring 536 is elastically deformed and stretched, and then the third buffer spring 536 plays a role of buffering and preventing hands from being pinched. Specifically, after the microphone 52 is driven by the automatic microphone lifting mechanism 51 to descend and be accommodated in the case 1, the microphone flip 3 needs to be closed; therefore, the second pull rod 532 drives the microphone flip 3 to swing toward the microphone extension opening 12, and at this time, if the hand of the user is placed in the microphone extension opening 12, and if the third buffer spring 536 is not present, the swinging closing action of the microphone flip 3 will exert a large force on the hand of the user, and the hand clamping phenomenon will occur, so that the hand of the user is seriously injured. Due to the third buffer spring 536 of the present embodiment, a good buffering effect is achieved, the acting force when the microphone flip 3 touches the human hand is weakened, and the time when the microphone flip 3 touches the human hand is slowed down, so that the injury degree of the human hand is reduced.

Specifically, the second positioning sliding member 533, the positioning member 5312 and the connecting member 5352 may be screws or bolts.

In order to further play a role of buffering and preventing hands from being clamped, a fourth buffer spring 537 is connected between the inner wall of the case 1 and the second pull rod 532 in the embodiment. At the in-process that second pull rod 532 reciprocated, elastic deformation takes place for fourth buffer spring 537, provides the cushioning effect by fourth buffer spring 537, prevents that second pull rod 532 atress from moving too fast, plays the purpose that the buffering was prevented tong.

In order to facilitate the second pull rod 532 to open and close the microphone flip 3 smoothly, in this embodiment, the microphone flip 3 is rotatably disposed on the inner wall of the case 1 through a connecting block 31, and the upper end of the second pull rod 532 is rotatably connected to the connecting block 31. Because the second pull rod 532, the connecting block 31 and the microphone flip 3 rotate adaptively, the microphone flip 3 can be opened and closed smoothly by the second pull rod 532.

When the microphone flip 3 needs to be opened so that the microphone 52 can be extended out from the microphone extension port 12 for use, the microphone automatic lifting mechanism 51 drives the microphone lifting bracket 510 to move upward, and then the microphone lifting bracket 510 drives the pushing member 534 to move upward, and the lower hook 5342 of the pushing member 534 applies an upward acting force to the second positioning slider 533, as shown in fig. 15, 16 and 20, so that the second positioning slider 533 moves upward in the second vertical sliding hole 53111 until the second positioning slider 533 slides into the second inclined sliding hole 53112; in the process, the pushing member 534 continuously moves upwards, so that the pushing block 535 continuously moves upwards and returns under the action of the elastic restoring force of the third buffer spring 536; then, as the second positioning sliding piece 533 slides into the second inclined sliding hole 53112, the lower hook 5342 of the pushing piece 534 is separated from the second positioning sliding piece 533; the push-up block 535 moves upward to abut against the second positioning sliding member 533, so as to prevent the second positioning sliding member 533 from sliding out of the second inclined sliding hole 53112, and the second positioning sliding member 533 is limited in the second inclined sliding hole 53112, as shown in fig. 21.

In the process, the second pull rod 532 moves upwards, so that the second pull rod 532, the connecting block 31 and the microphone flip 3 are adaptively rotated, the microphone flip 3 is driven to move away from the microphone extension port 12, and the microphone extension port 12 is completely opened; then, the microphone lifting bracket 510 moves upward continuously, and finally drives the microphone 52 to extend out of the microphone extension opening 12 for use.

When the microphone 52 needs to be retracted into the chassis 1 after being used, the microphone automatic lifting mechanism 51 drives the microphone lifting bracket 510 and the microphone 52 to move downward until the upper hook 5341 of the pushing member 534 on the microphone lifting bracket 510 moves downward to contact with the second positioning slider 533, and the upper hook 5341 acts downward on the second positioning slider 533, so that the second positioning slider 533 slides out of the second inclined sliding hole 53112 along the inclined inner wall of the second inclined sliding hole 53112 until entering the second vertical sliding hole 53111, which is changed from the state shown in fig. 21 to the state shown in fig. 20; then, as the pushing member 534 moves downwards, the second positioning sliding member 533 is driven to move downwards in the second vertical sliding hole 53111; meanwhile, the pushing member 534 pushes the pushing block 535 downwards, so that the pushing block 535 moves downwards vertically along the positioning member 5312 on the second fixing seat 531, and the third buffer spring 536 is stretched, as shown in fig. 15. In the process that the second positioning sliding member 533 moves down, the microphone 52 is completely retracted into the case 1, and at the same time, as the second pull rod 532 moves down, the second pull rod 532 pulls the connection block 31 downward, so that the second pull rod 532, the connection block 31 and the microphone flip 3 adaptively rotate, thereby moving the microphone flip 3 to the microphone extension opening 12 to hold the microphone extension opening 12, as shown in fig. 15, completing the retraction of the microphone 52.

In this embodiment, as shown in fig. 22, the microphone automatic lifting mechanism 51 includes a microphone lifting rack 5111 vertically disposed in the case 1, a microphone lifting support 510 slidably disposed in the case 1, a microphone lifting driving motor 512 disposed in the case 1 and connected to the microphone lifting support 510, and a microphone lifting transmission gear 513 disposed on an output shaft of the microphone lifting driving motor 512 and engaged with the microphone lifting rack 5111, and the microphone 52 is disposed on the microphone lifting support 510. The microphone lifting driving motor 512 provides driving force to drive the microphone lifting transmission gear 513 to rotate, and since the microphone lifting rack 511 is fixed in the case 1, the microphone lifting transmission gear 513 must move up and down along the microphone lifting rack 511 when rotating, thereby driving the microphone lifting support 510 and the microphone 52 to do lifting movement. For example, when the microphone lift transmission gear 513 rotates clockwise, the microphone lift bracket 510 and the microphone 52 move upward, and conversely, the microphone lift bracket 510 and the microphone 52 move downward.

In the embodiment, the microphone lifting rack 511 is meshed with the microphone lifting transmission gear 513, so that the lifting movement is realized, the noise is low, the operation is stable and stable, and the service life is long.

Simultaneously, in order to improve microphone lifting support 510 when being elevating movement, can not take place the slope, this embodiment is in microphone lifting support 510 both ends difference fixedly connected with at least one lift direction slider 514 be formed with on the machine case 1 inner wall and supply lift direction slider 514 embedding and the gliding lift direction spout that goes up and down (not seen in the figure) for microphone lifting support 510 is under the drive of microphone lift driving motor 512, is vertical motion along lift direction spout, and the slope phenomenon can not appear, improves microphone lifting support 510 and microphone 52 and is elevating movement's stability and accuracy.

Example four:

the main difference between the present embodiment and the third embodiment is that, as shown in fig. 22, a microphone lifting and positioning mechanism 54 is disposed in the casing 1, the microphone lifting and positioning mechanism 54 includes a lifting and lowering slide plate 541 disposed on the inner wall of the casing 1, a microphone positioning frame 542 disposed at the upper end of the lifting and lowering slide plate 541, and a second return spring 543 connected between the lower end of the lifting and lowering slide plate 541 and the inner wall of the casing 1, wherein a microphone through hole 5420 for the microphone 52 to pass through is formed on the microphone positioning frame 542, and a push connecting block 5410 located right below the microphone lifting and lowering support 510 is disposed at the lower end of the lifting and lowering slide plate 541; a rubber plug 5421 matched with the microphone extension opening 12 is arranged on the microphone perforation 5420 of the microphone positioning frame 542. The rubber plug 5421 has certain elasticity and flexibility, and plays a certain role in protecting the microphone 52; meanwhile, after the microphone 52 rises to the right position, the rubber plug 5421 is matched with the microphone extension port 12 to seal the microphone extension port 12, so that the dust-proof function in the case 1 is achieved.

In the process that the microphone lifting support 510 drives the microphone 52 to do lifting movement, the microphone 52 is limited in the microphone through hole 5420, so that the phenomenon of random swing cannot occur, and the microphone 52 can stably rise and fall.

Specifically, in the process that the microphone lifting bracket 510 drives the microphone 52 to descend, the microphone lifting bracket 510 synchronously pushes the pushing connecting block 5410 at the lower end of the lifting sliding plate 541 downwards, so that the lifting sliding plate 541 drives the microphone positioning frame 542 to synchronously move downwards, and the second return spring 543 is stretched to deform; when the microphone lifting bracket 510 drives the microphone 52 to ascend, the microphone lifting bracket 510 releases the acting force on the lifting slide plate 541, and the lifting slide plate 541 drives the microphone positioning frame 542 to restore and move upwards under the action of the elastic restoring force of the second restoring spring 543, so that the microphone positioning frame has an automatic return function; therefore, in the process of the microphone 52 being lifted or lowered by the microphone lifting bracket 510, the microphone 52 is positioned by the microphone positioning frame 542 of the microphone lifting positioning mechanism 54, so as to prevent the microphone 52 from swinging randomly and improve the stability and accuracy of the lifting and lowering of the microphone 52.
