Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

The first embodiment is as follows:

referring to fig. 1 and 2, an embodiment of the present invention provides an automatic opening and closing mechanism for a microphone flip, including a case 1, a microphone extension 12 is disposed at an upper end of the case 1, and a microphone flip 3 is disposed on the microphone extension 12. The automatic opening and closing mechanism for the microphone flip cover of the present embodiment further includes at least one automatic opening and closing component 53 for the microphone flip cover, which is disposed in the case 1 and connected to the microphone flip cover 3. Specifically, as shown in fig. 3 and 4, the microphone flip automatic opening and closing mechanism 53 includes a fixed seat 531 disposed at the lower portion of the inner side of the chassis 1, a pull rod 532 rotatably connected to the microphone flip 3, a positioning slider 533 slidably disposed on the fixed seat 531 and connected to the pull rod 532, a pushing member 534 movably disposed in the chassis 1 and acting on the positioning slider 533, an upper pushing block 535 slidably disposed on the fixed seat 531 and located below the positioning slider 533, and a first buffer spring 536 connected between the upper pushing block 535 and the inner side of the chassis 1, wherein a first longitudinal sliding hole 5311 for the positioning slider 533 to slide is formed on the fixed seat 531, and the first longitudinal sliding hole 5311 mainly includes a vertical sliding hole 53111 and an oblique sliding hole 53112 formed by bending the upper portion of the vertical sliding hole 53111 toward the inner side of the chassis 1, as shown in fig. 6.

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

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

In this embodiment, the pushing member 534 can be driven by the automatic microphone lifting mechanism 51 inside the chassis 1 to move up and down. Specifically, the pusher 534 is provided on the microphone lifting bracket 510 of the automatic microphone lifting mechanism 51, as shown in fig. 10.

Specifically, as shown in fig. 7, 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 down, the upper hook 5341 acts on the positioning sliding member 533 downward, so that the positioning sliding member 533 slides out of the oblique sliding hole 53112 along the inclined inner wall of the oblique sliding hole 53112 until entering the vertical sliding hole 53111; then, as the pushing member 534 moves downward, the positioning sliding member 533 is driven to move downward in the 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 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 inclined sliding hole 53112 and entering the vertical sliding hole 53111. Therefore, the positioning sliding member 533 can smoothly slide out of the oblique sliding hole 53112 and enter the vertical sliding hole 53111, and the sliding stability of the positioning sliding member 533 is improved.

Meanwhile, as shown in fig. 7, 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 upwards on the positioning slider 533, so that the positioning slider 533 moves upwards vertically along the vertical sliding hole 53111 until entering the oblique sliding hole 53112, so that the positioning slider 533 is limited in the oblique 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 plane 53421, when the pushing member 534 pushes the positioning sliding member 533 to move up to the connection between the vertical sliding hole 53111 and the oblique sliding hole 53112, the positioning sliding member 533 slides in the direction of the oblique sliding hole 53112 under the guiding action of the lower guiding inclined plane 53421 of the lower hook 5342, and thus slides into the oblique sliding hole 53112. Therefore, the positioning slider 533 can smoothly slide into the inclined sliding hole 53112 from the vertical sliding hole 53111, and the stability of sliding of the positioning slider 533 is improved.

Specifically, as shown in fig. 4, 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 inner side of the chassis. Due to the arrangement of the limiting guide inclined plane 5350, the positioning sliding piece 533 sliding into the inclined sliding hole 53112 is limited conveniently, and the positioning sliding piece 533 is prevented from sliding out.

As for the combination manner of the pushing-up block 535 and the fixing base 531, as shown in fig. 4, in this embodiment, a second longitudinal sliding hole 5351 is formed on the pushing-up block 535, at least one positioning member 5312 is disposed on the fixing base 531, preferably, the number of the positioning members 5312 is two, and the positioning members 5312 are embedded in the second longitudinal sliding hole 5351. Therefore, under the matching action of the positioning member 5312 and the second longitudinal sliding hole 5351, the push-up block 535 can vertically slide on the fixing base 531 along the positioning member 5312.

Specifically, as shown in fig. 5, a connecting member 5352 is disposed on the push-up block 535, and the first buffer spring 536 is connected between the connecting member 5352 and the fixing seat 531. Therefore, when the push-up block 535 slides up and down along the fixing base 531, the first buffer spring 536 can provide elastic restoring force.

Meanwhile, as for the effect of the first buffer spring 536, in the process of closing the microphone flip 3 onto the microphone extension opening 12, due to the existence of the first buffer spring 536, when the pushing member 534 applies a downward acting force to the positioning sliding member 533, the pushing member 535 is applied with a downward acting force at the same time, so that the first buffer spring 536 is elastically deformed and stretched, and then the first 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 microphone flip 3 is driven by the pull rod 532 to swing toward the microphone extension opening 12, and at this time, if the hand of a person is placed in the microphone extension opening 12, and if the first buffer spring 536 is not present, the swing closing action of the microphone flip 3 will exert a large force on the hand of the person, and the hand clamping phenomenon will occur, so that the hand of the person is seriously injured. Due to the existence of the first buffer spring 536 of the embodiment, a good buffering effect is achieved, the acting force of the microphone flip 3 when touching a human hand is weakened, and the time of the microphone flip 3 when touching the human hand is slowed down, so that the injury degree of the human hand is reduced.

Specifically, the 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 in buffering and preventing hands from being clamped, a second buffer spring 537 is connected between the inner wall of the case 1 and the pull rod 532 in the embodiment. At the in-process that pull rod 532 reciprocated, elastic deformation takes place for second buffer spring 537, provides the cushioning effect by second buffer spring 537, prevents that pull rod 532 atress from removing at the excessive speed, plays the buffering and prevents the purpose of tong.

In order to facilitate the smooth opening and closing of the microphone flip 3 by the pull rod 532, in the 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 pull rod 532 is rotatably connected with the connecting block 31. Because the pull rod 532, the connecting block 31 and the microphone flip 3 are adaptively rotated, the microphone flip 3 can be smoothly opened and closed by the pull rod 532.

When the microphone flip 3 needs to be opened so that the microphone 52 can be extended out of the microphone extension port 12 for use, the microphone automatic lifting mechanism 51 drives the microphone lifting bracket 510 to move upward, 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 positioning slider 533, as shown in fig. 3, 4 and 8, so that the positioning slider 533 moves upward in the vertical sliding hole 53111 until the positioning slider 533 slides into the oblique 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 first buffer spring 536; then, as the positioning sliding piece 533 slides into the oblique sliding hole 53112, the lower hook 5342 of the pushing piece 534 is separated from the positioning sliding piece 533; the push-up block 535 moves upward to abut against the positioning sliding member 533, so as to prevent the positioning sliding member 533 from sliding out of the inclined sliding hole 53112, and the positioning sliding member 533 is limited in the inclined sliding hole 53112, as shown in fig. 9.

In the process, the pull rod 532 moves upwards, so that the 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 positioning slider 533, and the upper hook 5341 acts downward on the positioning slider 533, so that the positioning slider 533 slides out of the inclined sliding hole 53112 along the inclined inner wall of the inclined sliding hole 53112 until entering the vertical sliding hole 53111, that is, the state in fig. 9 is changed to the state in fig. 8; then, with the downward movement of the pushing member 534, the positioning sliding member 533 is driven to move downward in the vertical sliding hole 53111; meanwhile, the pushing member 534 pushes the pushing block 535 downward, so that the pushing block 535 moves vertically downward along the positioning member 5312 on the fixing base 531, and the first buffer spring 536 is stretched, as shown in fig. 3. In the process that the positioning sliding member 533 moves down, the microphone 52 is completely retracted into the case 1, and meanwhile, as the pull rod 532 moves down, the pull rod 532 pulls the connection block 31 downward, so that the 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. 3, completing the retraction of the microphone 52.

In this embodiment, as shown in fig. 10, the microphone automatic lifting mechanism 51 of the microphone automatic extending and retracting device 5 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.

The automatic opening and closing mechanism for the microphone flip cover is applied to a multifunctional conference all-in-one machine, is particularly suitable for being installed in places such as conference rooms, education institutions and training institutions, and achieves paperless office speech. When the microphone flip automatic opening and closing mechanism is installed, the microphone flip automatic opening and closing mechanism can be integrally embedded into a table, the upper end face of the case 1 can be flushed with the table top, the table top position is not occupied, the whole case is neat and attractive, the microphone flip automatic opening and closing mechanism is not required to be additionally carried in use at every time, and the microphone flip automatic opening and closing mechanism is convenient to use and high in practicability.

Example two:

the main difference between the present embodiment and the first embodiment is that, as shown in fig. 10, 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 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 541, and a return spring 543 connected between the lower end of the lifting and lowering slide 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 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 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 elastic restoring force of the return 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.
