[0041] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0042] Embodiment 1:

[0043] Please refer to Figures 1 to 4The present embodiment provides a multifunctional integrated machine, including a chassis 1, wherein a display screen extension opening 11 and a microphone extension opening 12 are respectively provided at the upper end of the chassis 1, a display screen flip cover 10 is provided on the display screen extension opening 11, and a microphone flip cover 13 is provided on the microphone extension opening 12. The multifunctional integrated machine of the present embodiment further includes an automatic display screen lifting mechanism 2 provided in the chassis 1, a display screen 3 provided on the automatic display screen lifting mechanism 2 and capable of extending from the display screen extension opening 11, at least one automatic display screen flip cover opening and closing mechanism 4 provided in the chassis 1 and connected to the display screen flip cover 10, an automatic microphone lifting mechanism 5 provided in the chassis 1, a microphone 6 provided on the automatic microphone lifting mechanism 5 and capable of extending from the microphone extension opening 12, and at least one automatic microphone flip cover opening and closing mechanism 7 connected to the microphone flip cover 13.

[0044] The automatic display lifting mechanism 2 can drive the display screen 3 to do lifting movement, and the automatic display screen flip cover opening and closing mechanism 4 can control the opening and closing of the display screen flip cover 10, so that the display screen 3 can be extended from the display screen extension port 11 for use; at the same time, the automatic microphone lifting mechanism 5 can drive the microphone 6 to do lifting movement, and the automatic microphone flip cover opening and closing mechanism 7 can control the opening and closing of the microphone flip cover 13, so that the microphone 6 can be extended from the display screen extension port 11 for use.

[0045] In this embodiment, if Figure 3 As shown, the automatic display screen lifting mechanism 2 comprises a display screen lifting rack 21 and at least one lifting guide rod 22 respectively vertically arranged in the chassis 1, a display screen lifting bracket 23 arranged in the chassis 1 and slidably arranged on the lifting guide rod 22, a display screen lifting driving motor 24 arranged in the chassis 1 and connected to the display screen lifting bracket 23, and a display screen lifting transmission gear 25 arranged on the output shaft of the display screen lifting driving motor 24 and meshed with the display screen lifting rack 21. The display screen 3 is arranged on the display screen lifting bracket 23. The display screen lifting driving motor 24 provides driving force to drive the display screen lifting transmission gear 25 to rotate. Since the display screen lifting rack 21 is fixed in the chassis, when the display screen lifting transmission gear 25 rotates, it will move up and down along the display screen lifting rack 21, thereby driving the display screen lifting bracket 23 and the display screen 3 to perform lifting motion. For example, when the display screen lifting transmission gear 25 rotates clockwise, the display screen lifting bracket 23 and the display screen 3 perform an ascending motion, and vice versa, the display screen lifting bracket 23 and the display screen 3 perform a descending motion.

[0046] In this embodiment, the display screen lifting rack 21 is meshed with the display screen lifting transmission gear 25 to achieve lifting movement, with low noise, stable and smooth operation and long service life.

[0047] At the same time, in order to prevent the display screen lifting bracket 23 from tilting during the lifting movement, in this embodiment, at least one lifting guide slide 26 is movably sleeved on the lifting guide rod 22, and the back of the display screen lifting bracket 23 is fixedly connected to the lifting guide slide 26, so that the display screen lifting bracket 23, driven by the display screen lifting drive motor 24, moves vertically along the lifting guide rod 22 without tilting, thereby improving the stability and accuracy of the lifting movement of the display screen lifting bracket 23 and the display screen 3.

[0048] In this embodiment, if Figure 4 and Figure 5 As shown, the display screen flip cover automatic opening and closing mechanism 4 includes a fixed base 41 arranged at the lower inner side of the chassis 1, a pull plate 42 rotatably connected to the display screen flip cover 10, a slide plate 43 slidably connected between the pull plate 42 and the fixed base 41, and a buffer spring 44 connected between the slide plate 43 and the pull plate 42. When the sliding plate 43 is subjected to force and pulls the pull plate 42 downward along the inside of the chassis, the buffer spring 44 is stretched. Since the pulling plate 42 and the display screen flip cover 10 are rotatably connected, the pulling plate 42 drives the display screen flip cover 10 to swing toward the display screen extension opening 11, thereby sealing the display screen extension opening 11, that is, closing the display screen flip cover 10, so that the display screen 3 can be sealed and stored in the chassis; when the force on the sliding plate 43 disappears, under the elastic restoring force of the buffer spring 44, the sliding plate 43 moves up and resets, and pushes the pulling plate 42 to move upward along the inside of the chassis. Since the pulling plate 42 and the display screen flip cover 10 are rotatably connected, the pulling plate 42 drives the display screen flip cover 10 to swing toward the side of the display screen extension opening 11, thereby opening the display screen extension opening 11, so that the display screen 3 can be extended from the display screen extension opening 11.

[0049] Specifically, a fixed seat slide groove 411 is formed on the fixed seat 41, and a pull plate lower slide groove 421 is formed on the pull plate 42. The upper end of the slide plate 43 is provided with at least one middle positioning slide 431 extending into the pull plate lower slide groove 421, and the lower end is provided with a lower positioning slide 432 extending into the fixed seat slide groove 411. Specifically, the pull plate lower slide groove 421 and the fixed seat slide groove 411 are both bar slide grooves, and the middle positioning slide 431 and the lower positioning slide 432 are both screws or bolts. The middle positioning slide 431 can slide up and down along the pull plate lower slide groove 421, and the lower positioning slide 432 can slide up and down along the fixed seat slide groove 411. The combination of the pull plate lower slide groove 421 and the fixed seat slide groove 411 can not only provide a vertical guide for the up and down movement of the slide plate 43, but also limit the up and down sliding range of the slide plate 43 to ensure that the opening and closing stroke of the display flip cover 10 is the same each time.

[0050] At the same time, in order to prevent the pull plate 42 from tilting left and right during the process of moving up and down to drive the display screen flip cover 10 to swing, a pull plate slide groove 422 is formed on the pull plate 42 in this embodiment. Specifically, the pull plate slide groove 422 is an arc-shaped slide groove; an upper positioning slide 14 extending into the pull plate slide groove 422 is provided on the inner wall of the chassis 1. Specifically, the upper positioning slide 14 is a screw or a bolt. Therefore, under the limitation of the pull plate slide groove 422 and the upper positioning slide 14, the pull plate 42 will not tilt left and right during the process of moving up and down, thereby improving the stability of the pull plate 42 moving up and down. At the same time, since the pull plate slide groove 422 is an arc-shaped slide groove, a motion trajectory is provided for the pull plate 42 to drive the display screen flip cover 10 to swing, thereby improving the accuracy of the entire motion process.

[0051] At the same time, in order to allow the slide plate 43 to reset after it moves, this embodiment is provided with a pull plate hook 423 on the lower side of the pull plate 42, and a slide plate hook 433 on the side of the slide plate 43, and one end of the buffer spring 44 is hooked on the pull plate hook 423, and the other end is hooked on the slide plate hook 433.

[0052] At the same time, the buffer spring 44, the lower groove 421 on the pull plate and the fixed seat groove 411 are combined to play a role in buffering and preventing hand pinching. Specifically, after the display screen 3 is driven by the automatic display screen lifting mechanism 2 to be lowered and stored in the chassis, the display screen flip cover 10 needs to be closed; therefore, the slide plate 43 pulls the pull plate 42 to move downward along the inside of the chassis, and the pull plate 42 drives the display screen flip cover 10 to swing toward the display screen extension opening 11. At this time, if a person puts a hand into the display screen extension opening 11, if there is no buffer spring 44, the lower groove 421 on the pull plate and the fixed seat groove 411, the swinging and closing action of the display screen flip cover 10 will exert a large force on the hand, causing the hand pinching phenomenon, and the hand injury is relatively serious. However, due to the presence of the buffer spring 44, the lower groove 421 on the pull plate and the fixed seat groove 411 in this embodiment, a good buffering effect is played, which reduces the force when the display screen flip cover 10 hits the hand, and slows down the time when the display screen flip cover 10 hits the hand, thereby reducing the degree of hand injury.

[0053] Specifically, the display flip cover 10 of this embodiment is rotatably arranged on the inner wall of the chassis 1 through a connecting plate 45, and the upper end of the pull plate 42 is rotatably connected to the connecting plate 45. That is, the display flip cover 10 swings inside the chassis 1 to realize the opening and closing of the display extension 11.

[0054] As for how the slide plate 43 is triggered to move, in this embodiment, it is triggered by the automatic lifting mechanism 2 of the display screen. Specifically, a push arm 20 is extended and arranged on the side of the display screen lifting bracket 23 of the automatic lifting mechanism 2 of the display screen, which is located just above the lower positioning slide 432. When the automatic lifting mechanism 2 of the display screen drives the display screen 3 to descend and completely enter the chassis 1, the push arm 20 pushes the lower positioning slide 432 downward synchronously, thereby driving the slide plate 43 to move downward, so as to facilitate closing the display screen cover 10. When the automatic lifting mechanism 2 of the display screen drives the display screen 3 to rise, the display screen lifting bracket 23 rises accordingly, so that the push arm 20 releases the force acting on the lower positioning slide 432. Under the elastic restoring force of the buffer spring 44, the slide plate 43 moves up and resets, and pushes the pull plate 42 to move up along the inside of the chassis, and then the pull plate 42 drives the display screen cover 10 to swing to the side of the display screen extension opening 11, thereby opening the display screen extension opening 11, so that the display screen 3 can be extended from the display screen extension opening 11.

[0055] In this embodiment, if Figure 6 As shown, the microphone automatic lifting mechanism 5 includes a microphone lifting rack 51 vertically arranged in the case 1, a microphone lifting bracket 52 slidably arranged in the case 1, a microphone lifting driving motor 53 arranged in the case 1 and connected to the microphone lifting bracket 52, and a microphone lifting transmission gear 54 arranged on the output shaft of the microphone lifting driving motor 53 and meshed with the microphone lifting rack 51. The microphone 6 is arranged on the microphone lifting bracket 52. The microphone lifting driving motor 53 provides driving force to drive the microphone lifting transmission gear 54 to rotate. Since the microphone lifting rack 51 is fixed in the case 1, when the microphone lifting transmission gear 54 rotates, it will move up and down along the microphone lifting rack 51, thereby driving the microphone lifting bracket 52 and the microphone 6 to move up and down. For example, when the microphone lifting transmission gear 54 rotates clockwise, the microphone lifting bracket 52 and the microphone 6 move up, and vice versa, the microphone lifting bracket 52 and the microphone 6 move down.

[0056] This embodiment adopts the microphone lifting rack 51 to mesh with the microphone lifting transmission gear 54 to achieve lifting movement, with low noise, stable and smooth operation and long service life.

[0057] At the same time, in order to prevent the microphone lifting bracket 52 from tilting when it is lifted, in this embodiment, at least one lifting guide slider 55 is fixedly connected to both ends of the microphone lifting bracket 52, and a lifting guide slot 15 is formed on the inner wall of the chassis 1 for the lifting guide slider 55 to be embedded and lifted and slid. When driven by the microphone lifting drive motor 53, the microphone lifting bracket 52 moves vertically along the lifting guide slot 15 without tilting, thereby improving the stability and accuracy of the lifting and lowering movement of the microphone lifting bracket 52 and the microphone 6.

[0058] In this embodiment, the structure of the microphone cover automatic opening and closing mechanism 7 is the same as the structure of the display cover automatic opening and closing mechanism 4. Figure 4 Similarly, the microphone cover automatic opening and closing mechanism 7 controls the microphone cover 13 to cover the microphone extension opening 12 or open the microphone extension opening 12, so as to realize the opening and closing of the microphone cover 13, so as to facilitate the extension of the microphone 6 from the microphone extension opening 12, and after the microphone 6 is retracted into the chassis 1, the microphone extension opening 12 can be sealed to achieve the effect of sealed storage.

[0059] In this embodiment, the display screen 3 is mainly composed of a main screen on the front and a sub-screen on the back, that is, the display screen 3 is a double screen, and the driving principle of the main screen and the sub-screen is as follows: Figure 7 and Figure 8 As shown, the dual-screen display function is realized. For example, when a speaker uses the main screen to give a speech, the name, identity and other information of the speaker can be displayed on the secondary screen so that the audience can directly know the identity of the speaker.

[0060] At the same time, at least one of the main screen and the secondary screen is a touch screen, that is, it has a touch screen function. As for the driving principle of the touch screen, Figure 7 As shown,

[0061] In this embodiment, the chassis 1 is made of aluminum alloy, so that the chassis 1 has strong anti-interference ability; and the chassis 1 is an integrated structure formed by one-time die-casting, and the overall appearance is screw-free and beautiful.

[0062] In this embodiment, the lifting and lowering movements of the display screen 3 and the microphone 6 can be controlled separately, that is, only one of the two can be used, thereby improving practicality.

[0063] The multifunction machine provided in this embodiment can have single screen, dual screen, touch and microphone functions, and is particularly suitable for installation in conference rooms, educational institutions, training institutions and other places. During specific installation, the multifunction machine can be embedded in the table as a whole, as long as the upper end surface of the case 1 is flush with the tabletop. By using the multifunction machine provided in this embodiment, paperless office can be realized.

[0064] Embodiment 2:

[0065] The main difference between this embodiment and the first embodiment is that Figure 3 and Fig. 9As shown, an automatic display screen swing angle assembly 27 is respectively provided at both ends of the display screen lifting bracket 23, and the automatic display screen swing angle assembly 27 includes a swing angle linkage plate 271 rotatably arranged at the end of the display screen lifting bracket 23, and at least one first return spring 272 connected between the swing angle linkage plate 271 and the side of the display screen lifting bracket 23. The display screen 3 is arranged on the swing angle linkage plate 271 at both ends of the display screen lifting bracket 23; at the same time, a swing ejection member 16 for ejecting the lower part of the swing angle linkage plate 271 is provided on the inner wall of the chassis 1.

[0066] During the rising process of the display screen lifting bracket 23, the swing angle linkage plate 271 rises accordingly, and when the swing angle linkage plate 271 has not risen to the side of the swing ejector 16, the swing angle linkage plate 271 drives the display screen 3 to rise vertically together with the display screen lifting bracket 23 and extend out of the display screen extension port 11; and when the swing angle linkage plate 271 rises to the positive side of the swing ejector 16, the swing ejector 16 contacts the lower part of the swing angle linkage plate 271, and the swing ejector 16 pushes the lower part of the swing angle linkage plate 271 outward, so that the upper part of the swing angle linkage plate 271 swings inwardly by a certain angle, and drives the display screen 3 to swing by a corresponding angle, so as to achieve the purpose of tilting the display screen 3, which is convenient for the user to watch the content displayed on the display screen 3, and at this time the first return spring 272 is deformed. In the process that the swing angle linkage plate 271 drives the display screen 3 to descend and retract into the box body 1 together with the display screen lifting bracket 23, the swing angle linkage plate 271 continues to descend. When the lower part of the swing angle linkage plate 271 gradually separates from the swing ejector 16, the swing ejector 16 releases the force on the lower part of the swing angle linkage plate 271. Then, under the elastic restoring force of the first reset spring 272, the swing ejector 16 drives the display screen 3 to swing in the opposite direction and reset, and finally descends vertically and is retracted into the chassis 1.

[0067] Specifically, the upper portion of the swing angle linkage plate 271 is rotatably disposed on the display screen lifting bracket 23, a sliding hole 2711 is formed at the lower portion of the swing angle linkage plate 271, and a sliding shaft 231 inserted into the sliding hole 2711 is disposed on the side of the display screen lifting bracket 23; at the same time, a protrusion 2712 facing the swing ejector 16 is convexly disposed at the lower portion of the swing angle linkage plate 271. At the same time, a connecting block 232 is disposed upward at the end of the display screen lifting bracket 23, and the upper portion of the swing angle linkage plate 271 is rotatably connected to the connecting block 232 through a bolt 273.

[0068] When the swing angle linkage plate 271 rises to the positive side of the swing ejector 16, the swing ejector 16 contacts the protrusion 2712 of the swing angle linkage plate 271, and the swing ejector 16 pushes the protrusion 2712 outward, and the sliding hole 2711 on the swing angle linkage plate 271 slides along the sliding shaft 231 with the bolt 273 on the upper part of the swing angle linkage plate 271 as the center point, thereby swinging a certain angle. The combination of the sliding hole 2711 and the sliding shaft 231 limits the swing path and angle of the swing angle linkage plate 271, thereby improving the stability and accuracy of the swing angle linkage plate 271 when swinging, and preventing the swing from occurring randomly.

[0069] Specifically, one end of the first return spring 272 is connected to the upper part of the swing angle linkage plate 271, and the other end is connected to the lower part of the side of the display screen lifting bracket 23. When the swing angle linkage plate 271 swings with the bolt 273 at the upper part as the center point, the upper part of the swing angle linkage plate 271 drives the display screen 3 to swing at a corresponding angle, and the first return spring 272 is stretched and deformed accordingly. After the force that causes the swinging action disappears, the first return spring 272 provides a restoring force to reset.

[0070] Specifically, the swing ejector 16 is mainly composed of a bearing seat 161 arranged on the inner wall of the chassis 1, and at least one bearing 162 rotatably arranged on the bearing seat 161. When the swing angle linkage plate 271 rises to the point where the protrusion 2712 at the lower part contacts the lower edge of the bearing 162, the swing angle linkage plate 271 continues to rise, and the protrusion 2712 and the bearing 162 exert relative force, and the protrusion 2712 drives the bearing 162 to rotate until the swing angle linkage plate 271 rises to the positive side of the protrusion 2712. During this process, the bearing 162 pushes the protrusion 2712 outward to rotate the swing angle linkage plate 271. Therefore, the rotation of the rotatable bearing 162 provides an auxiliary effect for the swing angle linkage plate 271 to rise to its position, preventing the swing angle linkage plate 271 from being subjected to excessive resistance when the protrusion 2712 just contacts the bearing 162, thereby affecting the swing angle linkage plate 271 from continuing to rise to its position.

[0071] Embodiment three:

[0072] The main difference between this embodiment and the first or second embodiment is that: Figure 6 As shown, a microphone lifting and positioning mechanism 56 is arranged in the chassis 1, and the microphone lifting and positioning mechanism 56 includes a lifting slide plate 561 arranged on the inner wall of the chassis 1, a microphone positioning frame 562 arranged at the upper end of the lifting slide plate 561, and a second return spring 563 connected between the lower end of the lifting slide plate 561 and the inner wall of the chassis 1, wherein a microphone through hole 5621 for the microphone 6 to pass through is formed on the microphone positioning frame 562, and a pushing connecting block 5611 is arranged at the lower end of the lifting slide plate 561 and is located directly below the microphone lifting bracket 52.

[0073] At the same time, a rubber plug 564 matching the microphone extension port 12 is provided on the microphone through hole 5621 of the microphone positioning frame 562. The rubber plug 564 has a certain elasticity and softness, and plays a certain protective role for the microphone 6; at the same time, after the microphone 6 rises to its proper position, the rubber plug 564 matches the microphone extension port 12, and seals the microphone extension port 12, so as to achieve the function of dust and water protection inside the chassis 1.

[0074] When the microphone lifting bracket 52 drives the microphone 6 to perform lifting movement, since the microphone 6 is limited in the microphone through hole 5621, there will be no random swinging, so that the microphone 6 can rise and fall smoothly.

[0075] Specifically, in the process of the microphone lifting bracket 52 driving the microphone 6 to descend, the microphone lifting bracket 52 synchronously pushes the pushing connecting block 5611 at the lower end of the lifting slide 561 downward, so that the lifting slide 561 drives the microphone positioning frame 562 to move downward synchronously, and the second return spring 563 is stretched and deformed; and when the microphone lifting bracket 52 drives the microphone 6 to rise, the microphone lifting bracket 52 releases the force on the lifting slide 561, then under the elastic restoring force of the second return spring 563, the lifting slide 561 drives the microphone positioning frame 562 to reset and move upward, that is, it has an automatic return function; no matter whether the microphone lifting bracket 52 drives the microphone 6 to rise or fall, the microphone positioning frame 562 of the microphone lifting positioning mechanism 56 positions the microphone 6 to prevent the microphone 6 from swinging randomly, thereby improving the stability and accuracy of the rise and fall of the microphone 6.

[0076] Embodiment 4:

[0077] The main difference between this embodiment and any one of the embodiments 1 to 3 is that: Fig.10 As shown, a strip step 101 is protruded from the lower part of the two opposite sides of the display flip cover 10, and the strip step 101 extends along the length direction of the display flip cover 10; a strip clamping position 111 matching the strip step 101 is formed on the two opposite inner sides of the display extension opening 11. The strip step 101 on the display flip cover 10 is matched with the strip clamping position 111 on the display extension opening 11, and after the display screen 3 is retracted into the chassis 1, the display flip cover 10 can be tightly clamped in the display extension opening 11, as shown in FIG. Figure 2 As shown, effective sealing, dustproof and waterproof effects are achieved.
