Description

Technical Field

[0001] This utility model relates to the field of LCD screen technology, specifically to an ultra-thin integrated LCD screen lift device. Background Technology

[0002] An LCD screen uses liquid crystal material as its basic component, filling the space between two parallel plates. By applying voltage, the arrangement of molecules within the liquid crystal material is altered to achieve light blocking and transmission, displaying images of varying depths and textures. Furthermore, by adding a color filter layer with three primary colors between the two plates, color images can be displayed. LCD screens consume very little power, making them highly favored by engineers and suitable for battery-powered electronic devices.

[0003] Traditional lift screen frames made of aluminum alloy suffer from processing quality issues and cost concerns related to metal materials. Decorative doors easily scratch the frame. Traditional ultra-thin LCD screen lifts also have problems with their sliding doors not opening properly or getting stuck. Too many buttons on traditional lifts make it difficult for users to understand and use the product. Deformation of the lifting box during processing or welding leads to product quality issues. Traditional lifts using synchronous belts, chains, or wire ropes are difficult to maintain and prone to breakage. Traditional ultra-thin integrated LCD screen lifts require motors for tilting, resulting in high failure rates. In public settings, the ability for individual users to adjust the angle creates an untidy, unserious, and unsightly environment. Traditional photoelectric switches have inaccurate limit switches and can misalign. The large size and weight of traditional ultra-thin integrated LCD screen lifts can cause issues with table placement and table overloading. Utility Model Content

[0004] The purpose of this utility model is to provide an ultra-thin integrated LCD screen lift device to solve the problems mentioned in the background art.

[0005] An ultra-thin integrated LCD screen lifter includes a housing, a cover assembly on the top of the housing, a power assembly and a support assembly inside the housing, and a screen on the top of the power assembly.

[0006] The sealing assembly includes a panel fixedly connected to the upper end of the box. A through groove is provided at the center of the upper end of the panel. A control button is provided on the upper side edge of the panel. A movable door is provided on the inner side wall of the through groove. Both sides of the movable door are provided with pulleys.

[0007] A further improvement of this utility model is that: the movable door is provided with flip-up connectors on both sides, and the movable door is rotatably connected to the inner wall of the through groove through the lower end of the flip-up connectors.

[0008] By adopting the above technical solution, a mechanical flip-open mechanism for the movable door is achieved, preventing the inner wall of the groove from scratching the screen frame and screen body. The smoothness of the movable door's upward flip is improved by using pulleys to prevent the movable door from being unable to open or getting stuck when flipping downward. The panel is made of aluminum alloy profiles formed in one mold and machined by CNC. The control buttons have a USB interface, and the button functions are up, pause, down, and computer host power button, which solves the problem of traditional lifters having too many buttons, making it difficult for users to understand and use the product functions.

[0009] A further improvement of the present invention is that the supporting component includes a base plate fixedly connected to the bottom of the box, a rack fixedly connected to the upper center of the base plate, and an optical axis and a collision block fixedly connected to the upper end of the base plate.

[0010] A further improvement of this utility model is that the optical axis is located on both sides of the rack, and the upper ends of the rack and the optical axis are fixedly connected to the lower top of the housing.

[0011] By adopting the above technical solution, the lifting box is limited by the optical axis to prevent the lifting box from shifting inside the housing. The position of the lifting box is adjusted by the cooperation of the rack and pinion. The lifting box is limited by the stop block to prevent the lifting box from continuously moving down along the optical axis.

[0012] A further improvement of this utility model is that the contact blocks are provided in two sets.

[0013] A further improvement of the present invention is that: the power assembly includes a lifting box connected inside the housing, a motor is fixedly connected inside the lifting box, a gear is fixedly connected to the output end of the motor, a first micro switch and a second micro switch are also provided inside the lifting box, a collar is fixedly connected to the back of the lifting box, a support member is fixedly connected to the upper edge of the outer side of the lifting box, a screen frame is installed at the upper end of the support member, and the screen body is fixedly connected inside the screen frame.

[0014] By adopting the above technical solutions, the screen frame is made of ABS engineering plastic in one mold, which solves the processing quality problem and cost problem of traditional lifting device screen frames made of aluminum alloy. The lifting box is also made of ABS engineering plastic in one mold, which solves the product quality problem caused by deformation of the lifting box during processing or welding of traditional lifting devices. The elevation angle of the support component adopts a pulley mechanical control method, which is more stable and safer. This solves the problem of high failure rate of previous ultra-thin integrated LCD screen lifting devices that required electronic instruments to adjust the elevation angle, as well as the problem of untidy, unserious and unsightly scene caused by everyone being able to adjust various angles when using it in public places.

[0015] A further improvement of this utility model is that the collar passes through the outer surface of the optical axis, and the gear meshes with the rack.

[0016] By adopting the above technical solution, the cooperation of gears and racks prevents accidental breakage and facilitates maintenance.

[0017] A further improvement of this utility model is that the first micro switch and the second micro switch are located above the contact block.

[0018] By adopting the above technical solution, the lifting box is limited by the contact of the first micro switch and the second micro switch with the contact block, making the positioning of the lifting box more accurate and the limit more stable, thus solving the problem of inaccurate limit and deviation of the previous photoelectric switch limit.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By using ABS engineering plastic for the screen frame in one piece, the processing quality problem and cost problem of using aluminum alloy material for traditional lifting device screen frames are solved;

[0021] 2. The mechanical flip-open mechanism of the movable door prevents the inner wall of the groove from scratching the screen frame and screen body.

[0022] 3. The panel is made of aluminum alloy profiles formed in one mold and CNC machined. The control buttons have a USB interface and the button functions are up, pause, down, and computer host power button. This solves the problem of too many buttons on traditional lifters, making it difficult for users to understand and use the product functions.

[0023] 4. The lifting box adopts an ABS engineering plastic one-piece molding structure, which solves the product quality problems caused by deformation of the lifting box during the processing or welding of traditional lifting devices;

[0024] 5. The combination of gears and racks makes the structure safer, more stable, and easier to maintain, solving the problems of poor maintenance and breakage caused by previous synchronous belt, chain, and wire rope transmissions.

[0025] 6. The elevation angle is controlled by a pulley mechanical method through the support structure, which is more stable and safer. This solves the problem of high failure rate of the previous ultra-thin integrated LCD screen lift that required electronic instruments to adjust the elevation angle, as well as the problem of messy, unserious and unsightly scene caused by everyone being able to adjust various angles when used in public places.

[0026] 7. By adopting a limiting method that combines the first and second microswitches with the contact block, the positioning is more accurate and the limiting is more stable, solving the problems of inaccurate limiting and limit deviation caused by the previous photoelectric switch.

[0027] 8. Through structural optimization, the opening size is smaller and the weight is lighter, solving the problem that the traditional ultra-thin integrated LCD screen with screen has a large lifting size and a heavy overall weight, avoiding the situation that the table cannot fit the screen and the table is overloaded.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] like Figure 1-6As shown, this utility model provides an ultra-thin integrated LCD screen lifter, including a housing 1, a cover assembly 2 on the top of the housing 1, a power assembly 4 and a support assembly 3 inside the housing 1, and a screen 5 on the top of the power assembly 4.

[0038] The sealing assembly 2 includes a panel 21 fixedly connected to the upper end of the box 1. A through groove 22 is provided through the center of the upper end of the panel 21. A control button 25 is provided on the upper side edge of the panel 21. A movable door 23 is provided on the inner side wall of the through groove 22. Both sides of the movable door 23 are provided with pulleys 24.

[0039] The movable door 23 is provided with flip-up connectors on both sides, and the movable door 23 is rotatably connected to the inner wall of the through groove 22 through the lower end of the flip-up connectors.

[0040] The mechanical flip-opening mechanism of the movable door 23 prevents the inner wall of the slot 22 from scratching the screen frame 48 and screen body 5. The pulley 24 improves the smoothness of the upward flip of the movable door 23 to prevent it from being unable to open or getting stuck when it flips down. The panel 21 is made of aluminum alloy profile CNC machined in one mold. The control button 25 has a USB interface and the button functions are up, pause, down, and computer host power button, which solves the problem of too many buttons in traditional lifters, making it difficult for users to understand and use the product functions.

[0041] Example 2

[0042] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the support component 3 includes a bottom plate 31 fixedly connected to the bottom of the box 1, a rack 32 fixedly connected to the upper center of the bottom plate 31, and an optical axis 33 and a bumper 34 fixedly connected to the upper end of the bottom plate 31.

[0043] The optical axis 33 is located on both sides of the rack 32. The upper ends of the rack 32 and the optical axis 33 are fixedly connected to the lower top of the housing 1. Two sets of contact blocks 34 are provided.

[0044] The lifting box 41 is limited by the optical axis 33 to prevent the lifting box 41 from shifting inside the housing 1. The position of the lifting box 41 is adjusted by the cooperation of the rack 32 and the gear 43. The lifting box 41 is limited by the stop block 34 to prevent the lifting box 41 from continuously moving down along the optical axis 33.

[0045] Example 3

[0046] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the power assembly 4 includes a lifting box 41 connected inside the housing 1, a motor 42 fixedly connected inside the lifting box 41, a gear 43 fixedly connected to the output end of the motor 42, a first micro switch 44 and a second micro switch 45 also provided inside the lifting box 41, a collar 46 fixedly connected to the back of the lifting box 41, a support member 47 fixedly connected to the upper edge of the outer side of the lifting box 41, a screen frame 48 installed at the upper end of the support member 47, and a screen body 5 fixedly connected inside the screen frame 48;

[0047] The collar 46 passes through the outer surface of the optical axis 33, the gear 43 meshes with the rack 32, and the first micro switch 44 and the second micro switch 45 are located above the contact block 34.

[0048] The use of ABS engineering plastic for the screen frame 48, molded in one piece, solves the processing quality and cost issues associated with traditional aluminum alloy screen frames for lifting devices. The use of ABS engineering plastic for the lifting box 41, also molded in one piece, eliminates the deformation issues that traditional lifting devices experience during processing or welding, thus preventing product quality problems. The support component 47 employs a pulley-based mechanical control system for the elevation angle, ensuring greater stability and safety. This addresses the high failure rate of previous ultra-thin integrated LCD screen lifting devices that required electronic adjustment for elevation angle control, as well as the untidy, unserious, and unsightly appearance caused by individual adjustments in public spaces. The engagement of gear 43 and rack 32 prevents accidental breakage and facilitates maintenance. The first and second microswitches 44 and 45, respectively, contact the two sets of contact blocks 34 to limit the lifting box 41, resulting in more accurate and stable positioning. This eliminates the inaccurate and misaligned positioning issues associated with previous photoelectric switches.

[0049] The working principle of this ultra-thin integrated LCD screen lifter will be explained in detail below.

[0050] like Figure 1-6 As shown, when the screen body 5 needs to be raised, the motor 42 is started by pressing the rise button, which drives the gear 43 to move upward along the rack 32. This causes the collar 46 of the lifting box 41 to move upward along the outer surface of the optical axis 33. During the upward movement of the lifting box 41, the top of the screen frame 48 will hit the lower end of the movable door 23, thereby pushing the movable door 23 to flip up and open the through slot 22 so that the screen frame 48 and the screen body 5 can rise to the upper end of the panel 21.

[0051] When it is necessary to store the screen frame 48 and the screen body 5, press the down button to reverse the motor 42 and drive the gear 43 to move downward along the rack 32. When the upper end of the screen frame 48 is submerged in the through slot 22, the obstruction of the screen frame 48 to the movable door 23 disappears. Because the movable door 23 is equipped with a spring structure, the movable door is automatically pulled to close under the spring's rebound. As the lifting box 41 moves downward, the first micro switch 44 and the second micro switch 45 in the lifting box 41 contact the two sets of contact blocks 34 respectively, thereby triggering the first micro switch 44 and the second micro switch 45 to switch, causing the motor 42 to stop running, thereby stopping the movement of the screen body 5.

[0052] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
