Description

Technical Field

[0001] The present invention relates to the field of ultra-thin lifting computers, and specifically to an all-in-one computer with an ultra-thin liquid crystal screen that can be lifted Background Art

[0002] The liquid crystal lifter and the display are external devices that are not integrated together, let alone integrated with a CPU, memory, hard disk, motherboard, etc. The old ultra-thin liquid crystal lifter integrates a display screen on the basis of a conventional liquid crystal lifter. The display driver board is integrated inside the lifter, and then HDMI, VGA and other interfaces are transferred through the display driver board to the outside of the lifter box, and then an external computer signal is connected to display normally

[0003] Currently, most conference devices use ultra-thin all-in-one computers. To ensure the aesthetic feeling of the design, most of the lifting screens of the all-in-one computers adopt an ultra-thin design. This kind of design brings a strong sense of high technology to users and is therefore very popular. However, in order to keep the screen ultra-thin and the body lightweight, the current all-in-one computers have made lightweight treatment on the lifting system. Therefore, problems that cannot be avoided such as unstable lifting speed of the lifting screen, poor stability during lifting, and low structural strength after lifting have occurred. Moreover, the lifting life of most all-in-one computers is limited, and the problem of broken wiring harnesses often occurs after using for a period of time. Therefore, most of the existing all-in-one computers are labeled as vulnerable devices

[0004] Therefore, in order to overcome this problem, it is necessary to design an ultra-thin all-in-one computer that can achieve high connection strength and strong structural stability while showing an ultra-thin state Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an all-in-one computer with an ultra-thin liquid crystal screen that can be lifted, which solves the problems raised in the above background art

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An all-in-one computer with an ultra-thin liquid crystal screen that can be lifted includes a bottom case and a display screen assembly, and further includes a stable connection assembly for connecting the bottom case and the display screen assembly; it also includes two groups of stable drive assemblies symmetrically installed in the bottom case for driving the stable connection assembly; it includes two groups of stable support assemblies symmetrically installed in the bottom case and used to support the stable connection assembly after lifting; it also includes a wiring harness storage assembly installed in the bottom case, and when the stable connection assembly moves up and down, it can cause the wiring harness storage assembly to wind up the wiring harness

[0007] Preferably, the stable connection component includes an ultra-thin frame, which is fixedly mounted on the back of the display screen assembly; a spring component, one end of which is connected to the bottom of the ultra-thin frame, and the other end is connected to the inner top wall of the bottom shell. After the ultra-thin frame is fully extended from the bottom shell, the spring component is fully contracted. When the ultra-thin frame contracts into the bottom shell, the spring component begins to stretch; and a T-block is fixed on the ultra-thin frame. When the ultra-thin frame is fully extended from the bottom shell, the T-block is embedded in and rests against the inner top wall of the bottom shell.

[0008] Preferably, the top wall of the bottom shell is provided with a display screen outlet, the display screen outlet is a T-shaped structure, and the T-shaped block cooperates with the display screen outlet; the outer side of the ultra-thin frame is a rectangular frame, and the inner side is a cross beam.

[0009] Preferably, the stable support assembly includes a torsion shaft and a telescopic rod, the torsion shaft is installed on one side of the inner wall of the bottom shell, the telescopic rod is fixed to one side of the torsion shaft, and the torsion shaft can move the telescopic rod to the side of the lowered position of the ultra-thin frame; it also includes a telescopic pad, which is installed at the output end of the telescopic rod. The operation of the telescopic rod can make the telescopic pad collide with the bottom of the T-block.

[0010] Preferably, the stable drive assembly includes a slide rail A, a slider and a servo motor, the slide rail A is fixed on the inner wall of the bottom shell, the slider is in the slide rail A and is slidably connected thereto, the slider is fixed to the ultra-thin frame, and the servo motor is installed on the slider to drive the slider to slide along the slide rail A.

[0011] Preferably, the cable storage assembly includes a cable reel, roller A, roller B and two groups of pull wires. The cable reel is used to install the cable. One end of the cable reel is connected to the display screen assembly, and the other end is connected to the inner wall of the bottom shell. Roller A and roller B are respectively located on the front and back sides of the cable reel and distributed up and down. Roller A is fixed to the ultra-thin frame using an axis frame, and roller B is connected to the bottom shell for up and down sliding using an axis frame. The two groups of pull wires are respectively located on both sides of roller A and roller B. One end of the pull wire is fixedly connected to the axis frame of roller A, and the other end is fixed to the axis frame of roller B. Two pulleys are installed on the inner top wall of the bottom shell, and the pull wire passes over the pulleys; it also includes a counterweight, which is fixedly mounted on the axis frame of roller B.

[0012] Preferably, two symmetrical slide rails B are fixedly mounted on the inner wall of the bottom shell, and both ends of the shaft frame of the roller shaft B are clamped in the slide rails B and are slidably connected thereto.

[0013] Preferably, the output shaft of the servo motor is equipped with a gear, and one side of the slide rail A is provided with a tooth groove, and the gear is engaged with the tooth groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The ultra-thin LCD screen lifting all-in-one computer is provided with a stable connection component. The ultra-thin frame is connected to the back of the display screen assembly with multiple bolts, thereby increasing the connection area and increasing the structural strength of the display screen. When the display screen assembly is controlled to extend and retract up and down, the display screen assembly can be ensured not to shake. When it moves to the uppermost end, the T-block fits tightly with the upper end of the bottom shell. Therefore, after the display screen assembly is fully extended, it will not shake when it is touched. Therefore, when the display screen is sufficiently ultra-thin, the service life of the device can be increased.

[0015] The ultra-thin LCD screen lifting all-in-one computer is provided with a stable support component. After the display screen assembly is fully extended, a telescopic rod is used to support the display screen assembly and the bottom end of the ultra-thin frame, thereby stably supporting the display screen assembly. When the display screen assembly is extended for a long time, the pressure on the internal servo motor or other driving components can be reduced. After extension, the display screen assembly is less affected by its own weight, thus extending its service life.

[0016] The ultra-thin LCD screen lifting all-in-one computer is provided with a cable storage component. The cable reel is used to install and place the cable, which can provide preliminary protection for the cable. When the ultra-thin frame moves down with the display assembly, the roller A and the roller B are staggered to allow the cable to be reeled. When the ultra-thin frame moves up, the two rollers move away from each other to allow the cable to be unfolded. Therefore, compared with existing telescopic all-in-one computers, the cable will not fold. During the continuous extension and retraction process, the cable still moves according to the pre-set position, and the probability of damage is relatively low.

[0017] The ultra-thin LCD screen lifting all-in-one computer is provided with a spring assembly. When the display screen assembly moves downward, the spring assembly is stretched, and vice versa. Therefore, the spring assembly can balance the gravity of the display screen assembly. As a result, the servo motor used for driving the bottom has less pressure, a longer service life, and greater stability when extending and retracting. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0021] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0022] In the present application, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0023] In addition, in this application, descriptions such as "first" and "second" are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0024] As Figures 1 - 10 shown, a thin and ultra-thin LCD screen lifting all-in-one computer includes a bottom case 1 and a display screen assembly 2, and further includes a stable connection assembly 3 for connecting the bottom case 1 and the display screen assembly 2; It further includes two groups of stable driving assemblies 4 symmetrically installed in the bottom case 1 for driving the stable connection assembly 3; it includes two groups of stable supporting assemblies 5 symmetrically installed in the bottom case 1 and used for supporting the stable connection assembly 3 after lifting; it further includes a cable storage assembly 6 installed in the bottom case 1, and when the stable connection assembly 3 moves up and down, it can cause the cable storage assembly 6 to wind up the cable.

[0025] Currently, thin and ultra-thin lifting all-in-one computers are mainly applied to conference halls of various enterprises and institutions. The LCD screen is automatically hidden inside the chassis, which is convenient to use. When in use, it rises on the desktop, and when not in use, it is hidden in the chassis, having the advantages of beautiful appearance and not being easily scratched. However, during actual use, since the display screen is set to be relatively thin, it is extremely easy to shake and is also unstable when subjected to external forces. Therefore, the stable connection assembly 3 of this solution connects the display screen assembly 2 and the bottom case 1 together. As a link connecting the two, the stable connection assembly 3 can achieve a good stable connection effect on the display screen assembly 2 and can also achieve a stable connection effect on the bottom case 1.

[0026] Currently, the general lifting system is controlled by a group of servo systems. This solution sets two groups of stable driving assemblies 4 and distributes them symmetrically. Not only is the lifting load-bearing capacity large, but the two symmetrically arranged groups are more stable during operation.

[0027] Different from the prior art, this solution also sets two stable supporting assemblies 5. The stable supporting assemblies 5 can play a long-term supporting effect at the bottom of the display screen assembly 2 after it is fully lifted. When the display screen assembly 2 is not retracted for a long time, it can slow down the pressure borne by the internal precision components and reduce the error caused by the wear of the internal parts of the device.

[0028] As Figures 3 - 10, in an optional embodiment, the stable connection component 3 includes an ultra-thin frame 301 fixedly installed on the back of the display screen component 2; a spring component 302, one end of the spring component 302 is connected to the bottom of the ultra-thin frame 301, and the other end is connected to the inner top wall of the bottom case 1. After the ultra-thin frame 301 completely extends out of the bottom case 1, the spring component 302 is in a fully contracted state. When the ultra-thin frame 301 contracts into the bottom case 1, the spring component 302 begins to stretch; it further includes a T-shaped block 303 fixed on the ultra-thin frame 301. After the ultra-thin frame 301 completely extends out of the bottom case 1, the T-shaped block 303 is embedded and abuts against the inner top wall of the bottom case 1.

[0029] In this embodiment, the ultra-thin frame 301 is fixed to the back of the display screen component 2 by a number of positioning bolts, mainly connected to the display screen backplane, and the ultra-thin frame 301 is made of aluminum alloy. The cross-sectional shape is U-shaped or uses special-shaped aluminum alloy, which can still have high structural strength when set to be relatively thin. Moreover, the area of the ultra-thin frame 301 is only smaller than that of the display screen component 2. Therefore, after connection, the display screen component 2 is not easily bent by external forces.

[0030] The spring component 302 mainly includes a spring and connectors at both ends. The length of the spring satisfies the stretching after the display screen component 2 completely falls into the bottom case 1, and the elastic coefficient of the spring is correspondingly matched with the total weight of the display screen component 2 and the ultra-thin frame 301. Specifically, it should be satisfied that when the display screen component 2 and the ultra-thin frame 301 rise, only a relatively small driving force needs to be provided additionally. There are multiple T-shaped blocks 303, and the upper ends of the T-shaped blocks 303 are chamfered to avoid damaging the bottom case 1 due to errors.

[0031] In an optional embodiment, the top wall of the bottom case 1 is provided with a display screen outlet 7. The display screen outlet 7 is of a T-shaped structure, and the T-shaped block 303 cooperates with the display screen outlet 7; the outer side of the ultra-thin frame 301 is a rectangular frame, and the inner side is a cross-shaped beam.

[0032] In this embodiment, the cross-section of the display screen outlet 7 is an inverted T-shaped structure, and the two ends of its bottom are also chamfered. When the T-shaped block 303 is inserted, it is basically not hindered.

[0033] The cross-shaped beam in the middle of the ultra-thin frame 301 can not only increase the connection strength of the structure but also reduce the local weight.

[0034] In an alternative embodiment, the stable support assembly 5 includes a torsion shaft 501 and a telescopic rod 502. The torsion shaft 501 is installed on one side of the inner wall of the bottom case 1, and the telescopic rod 502 is fixed to one side of the torsion shaft 501. The torsion shaft 501 can move the telescopic rod 502 to one side of the descending position of the ultra-thin frame 301. It further includes a telescopic pad 503 installed at the output end of the telescopic rod 502. When the telescopic rod 502 operates, the telescopic pad 503 can abut against the bottom of the T-shaped block 303.

[0035] In this embodiment, the torsion shaft 501 includes a connecting shaft and a motor. The motor drives and controls the connecting shaft to rotate a certain angle through a speed reducer. Each time it rotates 90 degrees, the torsion shaft 501 itself can be perfectly hidden. The later rotation angle can be changed according to the width of the bottom case 1, as long as the torsion shaft 501 does not affect the retraction of the display screen assembly 2. The telescopic rod 502 can adopt an electric screw type telescopic device or an electro-hydraulic telescopic device, as long as it can meet linear motion or can maintain the support force for a long time.

[0036] The telescopic pad 503 is an elastic rubber pad and can contract when subjected to pressure from above and below.

[0037] In an alternative embodiment, the stable drive assembly 4 includes a slide rail A401, a slider 402, and a servo motor 403. The slide rail A401 is fixed to the inner wall of the bottom case 1. The slider 402 is located within the slide rail A401 and is slidably connected thereto. The slider 402 is fixed to the ultra-thin frame 301, and the servo motor 403 is installed on the slider 402 for driving the slider 402 to slide along the slide rail A401.

[0038] In this embodiment, the slider 402 fits tightly with the slide rail A401, and there is basically no shaking between the two. Therefore, the ultra-thin frame 301 connected to the slider 402 will not shake when moving up and down. Setting two sets of slide rails A401 and sliders 402 can further improve the stability during operation.

[0039] In an alternative embodiment, the flexible cable storage assembly 6 includes a flexible cable reel 601, a roller A 602, a roller B 603, and two groups of stay cables 604. The flexible cable reel 601 is used for installing the flexible cable. One end of the flexible cable reel 601 is connected to the display screen assembly 2, and the other end is connected to the inner wall of the bottom case 1. The roller A 602 and the roller B 603 are respectively located on the front and rear sides of the flexible cable reel 601 and are distributed vertically. The roller A 602 is fixed to the ultra-thin frame 301 by a shaft bracket, and the roller B 603 is slidably connected to the bottom case 1 up and down by a shaft bracket. The two groups of stay cables 604 are respectively located on both sides of the roller A 602 and the roller B 603. One end of the stay cable 604 is fixedly connected to the shaft bracket of the roller A 602, and the other end is fixedly connected to the shaft bracket of the roller B 603. Two pulleys 605 are installed on the inner top wall of the bottom case 1, and the stay cable 604 passes over the pulley 605; a counterweight 606 is further included, and the counterweight 606 is fixedly installed on the shaft bracket of the roller B 603.

[0040] In this embodiment, the flexible cable reel 601 is a hollow plastic tube and is in the shape of a thin sheet. When actually setting up the computer, the flexible cable connected to the screen needs to pass through the flexible cable reel 601, and the flexible cable reel 601 can play a role in protecting the flexible cable. The roller A 602 and the roller B 603 are both solid metal rods, which can guide the flexible cable reel 601 and prevent the flexible cable reel 601 from folding. The connection between the shaft bracket and the roller A 602 or the roller B 603 is a rotational connection, and a bearing is provided between them.

[0041] The stay cable 604 is a steel wire rope, and the pulley 605 plays a role in turning the stay cable 604. The counterweight 606 can keep a downward force on the roller B 603 all the time.

[0042] In an alternative embodiment, two symmetrical slide rails B 607 are fixedly installed on the inner wall of the bottom case 1, and both ends of the shaft bracket of the roller B 603 are stuck in the slide rails B 607 and are slidably connected to them.

[0043] In this embodiment, the slide rails B 607 are used to limit the roller B 603. A slide table matching the slide rails B 607 is also installed at the end of the roller B 603, so that it can only move up and down along the bottom case 1. Therefore, the flexible cable reel 601 restricted by it will also stick to the bottom case 1 when folding and is not easily damaged.

[0044] In an alternative embodiment, a gear is installed on the output shaft of the servo motor 403, and a tooth groove is provided on one side of the slide rail A 401, and the gear meshes with the tooth groove.

[0045] Working principle: Lifting state: The servo motor 403 operates, driving the slider 402 to slide upward along the slide rail A401. The ultra-thin frame 301 connected thereto will drive the display screen assembly 2 to rise. At this time, the spring assembly 302 begins to gradually contract as the ultra-thin frame 301 moves until the ultra-thin frame 301 moves to the uppermost end. At this time, the display screen assembly 2 completely extends out of the bottom case 1. At the same time, the roller A602 moves upward, and the roller B603 moves downward under the action of the counterweight 606. The cable reel 601 unfolds due to the upward movement of the ultra-thin frame 301 and unfolds in accordance with their dispersion directions, and is not affected by them; Stable state: The display screen assembly 2 completely extends out of the bottom case 1. At this time, the T-shaped block 303 moves into the display screen outlet 7. Then the torsion shaft 501 operates, causing the telescopic rod 502 to rotate below the T-shaped block 303. The telescopic rod 502 operates, and then the telescopic pad 503 tightly fits against the bottom of the T-shaped block 303, firmly pressing it against the display screen outlet 7; Retracting state: First, the telescopic rod 502 contracts, causing the telescopic pad 503 to leave the T-shaped block 303, and the torsion shaft 501 rotates in the reverse direction, retracting the telescopic rod 502 and leaving the descending path of the ultra-thin frame 301. The servo motor 403 drives the slider 402 to operate to lower the ultra-thin frame 301. At this time, the spring assembly 302 begins to stretch, and the roller A602 begins to move downward, and drives the roller B603 to move upward through the cable 604. The two move relative to each other, cross, and then move towards each other, so that the cable reel 601 can be folded in an S shape. Therefore, until the display screen assembly 2 is completely retracted into the bottom case 1, the cable reel 601 can be stacked in a double layer and will not be broken due to the action of the roller A602 and the roller B603.
