Description

Technical Field

[0001] The present invention relates to the field of ultra-thin lifting computers, in particular to an ultra-thin liquid crystal screen lifting all-in-one computer. Background Art

[0002] The LCD lift is an external device that is not integrated with the monitor, nor is it integrated with the CPU, memory, hard disk, motherboard, etc. The old ultra-thin LCD lift integrates the display screen on the basis of the conventional LCD lift. The display driver board is integrated into the lift, and then the HDMI, VGA and other interfaces are connected to the outside of the lift box through the display driver board, and then the external computer signal is connected to display normally.

[0003] At present, most conference equipment uses ultra-thin lifting all-in-one machines. In order to ensure the beauty of the design, the lifting screens of most lifting all-in-one machines adopt an ultra-thin design. This type of design brings a strong high-tech look and feel to users, and is therefore very popular. However, in order to keep the screen ultra-thin and the body light, the current lifting all-in-one machines have all been lightweighted on the lifting system. As a result, there are unavoidable problems such as unstable lifting speed of the lifting screen, poor stability during lifting, and low structural strength after lifting. Moreover, the lifting life of most lifting all-in-one machines is limited. Cable breakage is a common problem after a period of use. Therefore, most existing lifting all-in-one machines are labeled as fragile equipment.

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

[0005] In view of the shortcomings of the prior art, the present invention provides an ultra-thin LCD screen lift-type computer all-in-one, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an ultra-thin LCD screen lifting all-in-one computer, including a bottom shell and a display screen assembly, and also including a stable connection assembly for connecting the bottom shell and the display screen assembly; also including two groups of stable drive assemblies, symmetrically installed in the bottom shell, for driving the stable connection assembly; including two groups of stable support assemblies, symmetrically installed in the bottom shell, and used to support the stable connection assembly after lifting; also including a cable storage assembly, installed in the bottom shell, and the stable connection assembly can prompt the cable storage assembly to reel in the cable when moving up and down.

[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:

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0032] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0034] like Figures 1-10 As shown, an ultra-thin LCD screen lifting all-in-one computer includes a bottom shell 1 and a display screen assembly 2, and also includes a stable connection assembly 3 for connecting the bottom shell 1 and the display screen assembly 2;

[0035] It also includes two groups of stable driving components 4, which are symmetrically installed in the bottom shell 1 and are used to drive the stable connection component 3; it includes two groups of stable support components 5, which are symmetrically installed in the bottom shell 1 and are used to support the stable connection component 3 after it is raised; it also includes a cable storage component 6, which is installed in the bottom shell 1. When the stable connection component 3 moves up and down, it can prompt the cable storage component 6 to reel in the cable.

[0036] At present, the ultra-thin lifting all-in-one machine is mainly used in conference halls of various enterprises and institutions. The LCD screen is automatically hidden inside the chassis, which is convenient to use. It can be raised on the desktop when in use and hidden in the chassis when not in use. It has the advantages of beautiful appearance and not easy to be scratched. However, in actual use, the display screen is very prone to shaking due to its thin setting, and it is also unstable when subjected to external force. Therefore, the stable connection component 3 of this solution connects the display screen component 2 and the bottom shell 1 together. As a link connecting the two, the stable connection component 3 can achieve a better stable connection effect for the display screen component 2, and can also achieve a stable connection effect for the bottom shell 1.

[0037] The current lifting system is generally controlled by a set of servo systems. This solution sets two sets of stable drive components 4, and they are symmetrically distributed. Not only can the lifting and lowering withstand greater force, but the two symmetrically arranged groups are also more stable during operation.

[0038] Unlike the prior art, the present invention further provides two stabilizing support components 5. The stabilizing support components 5 can provide long-term support at the bottom of the display screen component 2 after the display screen component 2 is fully raised. When the display screen component 2 is not retracted for a long time, the pressure on the internal precision components can be reduced, thereby reducing the error caused by the wear of internal parts of the equipment.

[0039] like Figure 3-10In an optional embodiment, the stable connection component 3 includes an ultra-thin frame 301, which is fixedly mounted on the back of the display screen assembly 2; a spring component 302, one end of which 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 shell 1. After the ultra-thin frame 301 is fully extended from the bottom shell 1, the spring component 302 is fully contracted. When the ultra-thin frame 301 contracts into the bottom shell 1, the spring component 302 begins to stretch; and a T-block 303 is fixed on the ultra-thin frame 301. When the ultra-thin frame 301 is fully extended from the bottom shell 1, the T-block 303 is embedded in and rests against the inner top wall of the bottom shell 1.

[0040] In this embodiment, the ultra-thin frame 301 is fixed to the back of the display screen assembly 2 with a number of positioning bolts, and is mainly connected to the back panel of the display screen. The ultra-thin frame 301 is made of aluminum alloy, and the cross-sectional shape is U-shaped or a special-shaped aluminum alloy. It can still have a high structural strength while being thinner. Moreover, the area of ​​the ultra-thin frame 301 is only smaller than the display screen assembly 2, so after the connection, the display screen assembly 2 is not easily bent by external force.

[0041] The spring assembly 302 mainly includes a spring and connecting parts at both ends. The length of the spring meets the stretching of the display screen assembly 2 after it falls completely into the bottom shell 1, and the elastic coefficient of the spring is coordinated with the combined weight of the display screen assembly 2 and the ultra-thin frame 301. Specifically, it should meet the requirement that the display screen assembly 2 and the ultra-thin frame 301 only need to provide a small additional driving force when rising. There are multiple T-blocks 303, and the upper end of the T-block 303 is chamfered to avoid damage to the bottom shell 1 due to errors.

[0042] In an optional embodiment, the top wall of the bottom shell 1 is provided with a display screen outlet 7, which is 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 beam.

[0043] In this embodiment, the cross section of the display screen outlet 7 is an inverted T-shaped structure, and both ends of the bottom are chamfered, so that the T-shaped block 303 will not be hindered when being inserted.

[0044] The cross 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.

[0045] In an optional embodiment, the stabilizing 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 shell 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 the side of the lowered position of the ultra-thin frame 301; it also includes a telescopic pad 503, which is installed at the output end of the telescopic rod 502. The operation of the telescopic rod 502 can make the telescopic pad 503 collide with the bottom of the T-block 303.

[0046] In this embodiment, the torsion shaft 501 includes a connecting shaft and a motor. The motor drives the connecting shaft to rotate a certain angle through a reducer. Each time it rotates ninety degrees, the torsion shaft 501 itself can be perfectly hidden. The later rotation angle can be changed according to the width of the bottom shell 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 spiral telescope or an electro-hydraulic telescope, as long as it can meet the linear motion or can maintain the supporting force for a long time.

[0047] The telescopic pad 503 is an elastic rubber pad that can shrink when subjected to pressure from above and below.

[0048] In an optional embodiment, the stabilizing drive assembly 4 includes a slide rail A401, a slider 402 and a servo motor 403. The slide rail A401 is fixed on the inner wall of the bottom shell 1. The slider 402 is in the slide rail A401 and is slidably connected thereto. The slider 402 is fixed to the ultra-thin frame 301. The servo motor 403 is installed on the slider 402 for driving the slider 402 to slide along the slide rail A401.

[0049] 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. The provision of two sets of slide rails A401 and the slider 402 can further improve the stability during operation.

[0050] In an optional embodiment, the cable storage assembly 6 includes a cable reel 601, a roller A602, a roller B603, and two sets of pull wires 604. The cable reel 601 is used to install the cable. One end of the cable reel 601 is connected to the display assembly 2, and the other end is connected to the inner wall of the bottom shell 1. The roller A602 and the roller B603 are respectively located on the front and back sides of the cable reel 601 and are distributed up and down. The roller A602 is fixed to the ultra-thin frame 301 using an axis bracket. The roller B603 is connected to the bottom shell 1 by means of an axis frame for sliding up and down movement. Two sets of pull wires 604 are respectively located on both sides of the roller A602 and the roller B603. One end of the pull wire 604 is fixedly connected to the axis frame of the roller A602, and the other end is fixed to the axis frame of the roller B603. Two pulleys 605 are installed on the inner top wall of the bottom shell 1, and the pull wire 604 passes over the pulley 605; it also includes a counterweight 606, which is fixedly installed on the axis frame of the roller B603.

[0051] In this embodiment, the cable reel 601 is a hollow plastic tube in the shape of a thin sheet. When actually setting up the computer, the cable connected to the screen needs to be passed through the cable reel 601. The cable reel 601 can protect the cable. The roller A602 and the roller B603 are both solid metal rods that can guide the cable reel 601 without causing the cable reel 601 to fold. The connection between the shaft frame and the roller A602 or the roller B603 is a rotating connection, and a bearing is provided between the two.

[0052] The pull wire 604 is a steel wire rope, the pulley 605 serves to turn the pull wire 604, and the counterweight 606 can keep the roller shaft B603 always having a downward force.

[0053] In an optional embodiment, two symmetrical slide rails B607 are fixedly installed on the inner wall of the bottom shell 1, and both ends of the shaft frame of the roller shaft B603 are clamped in the slide rails B607 and are slidably connected thereto.

[0054] In this embodiment, the slide rail B607 is used to limit the roller shaft B603, and the end of the roller shaft B603 is also installed with a slide that cooperates with the slide rail B607, so that it can only move up and down along the bottom shell 1. Therefore, the cable roll 601 restricted by it will also stick to the bottom shell 1 when folded and is not easily damaged.

[0055] In an optional 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 A401, and the gear is engaged with the tooth groove.

[0056] Working principle:

[0057] Lifting state: The servo motor 403 is running, which can drive the slider 402 to slide upward along the slide rail A401. The ultra-thin frame 301 connected to it will lift the display assembly 2. At this time, the spring assembly 302 begins to gradually contract with the movement of the ultra-thin frame 301 until the ultra-thin frame 301 moves to the uppermost end. At this time, the display assembly 2 is completely extended from the bottom shell 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 is unrolled by the upward movement of the ultra-thin frame 301 and unrolls in the dispersion direction of the ultra-thin frame 301 and is not affected by the ultra-thin frame 301.

[0058] Stable state: The display assembly 2 is fully extended from the bottom housing 1. At this time, the T-shaped block 303 moves into the display screen outlet 7. Then, the torsion shaft 501 rotates, causing the telescopic rod 502 to rotate below the T-shaped block 303. The telescopic rod 502 rotates, and then the telescopic pad 503 tightly fits the bottom of the T-shaped block 303, firmly pressing it against the display screen outlet 7.

[0059] Retracted state: First, the telescopic rod 502 contracts, so that the telescopic pad 503 leaves the T-block 303, and the torsion shaft 501 rotates in the opposite 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 move the ultra-thin frame 301 downward. At this time, the spring assembly 302 begins to stretch, and the roller A602 begins to move downward, and moves up with the roller B603 through the pull wire 604. The two move oppositely and intertwine 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 shell 1, the cable reel 601 can be stacked in two layers and will not break due to the action of the rollers A602 and B603.

[0060] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0061] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
