Description

Technical Field

[0001] This utility model relates to the field of all-in-one LCD display technology, specifically an all-in-one LCD display with a lift-up mechanism. Background Technology

[0002] An all-in-one LCD display is an intelligent display device that integrates LCD technology, computer processing unit, input device and multimedia functions. With an LCD screen as its core, it realizes multiple functions such as information display, interactive operation and data processing through built-in hardware (such as motherboard, processor, memory, etc.) and software system. It does not require an additional computer host and is widely used in education, conferences, advertising, retail and other scenarios.

[0003] In related technologies, current LCD all-in-one displays generally have a fixed height and cannot be flexibly adjusted. This makes it difficult for users to make comfortable visual adjustments according to the actual usage scenario and their own height. Due to the lack of convenient height or tilt adjustment mechanisms, users often need to frequently adapt to the screen position at different distances or sitting postures, which not only reduces operating efficiency but also increases fatigue during long-term use.

[0004] Therefore, it is necessary to provide an all-in-one machine with a liftable LCD display to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a liftable LCD display all-in-one machine, which solves the problem that the height of current LCD display all-in-one machines is generally fixed and cannot be adjusted according to the distance and height of the user, resulting in low adjustment efficiency and inability to adjust quickly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a liftable LCD display all-in-one machine, comprising an LCD display all-in-one machine, a fixed frame fixedly connected to the bottom of the LCD display all-in-one machine, a limit plate fixedly connected to the rear side of the top of the fixed frame, a transmission component provided inside the limit plate, and a lifting adjustment component provided at the rear side of the LCD display all-in-one machine.

[0007] The transmission assembly is used to drive the lifting and adjusting assembly;

[0008] The height adjustment component is used to adjust the height of the all-in-one LCD display.

[0009] Preferably, the transmission assembly includes a rotating rod rotatably connected inside the limiting plate, a connecting rod fixedly connected to the surface of the rotating rod, a worm gear fixedly connected to the surface of the rotating rod, a worm meshing with the top of the worm gear, and a servo motor drivingly connected to the right side of the worm.

[0010] The above technical solution employs a combined structure of a rotating rod, connecting rod, worm gear, worm, and servo motor in its transmission components. The servo motor drives the worm to rotate, and the meshing transmission between the worm gear and the worm drives the rotating rod to rotate, thereby causing the connecting rod to move synchronously. This transmission method features precise transmission ratio, smooth operation, and excellent self-locking performance, effectively preventing accidental displacement caused by external forces during adjustment. Simultaneously, the precise control of the servo motor enables fine-tuning of the height of the LCD all-in-one machine, meeting the precise height requirements of different usage scenarios. The fixed connection between the rotating rod and the connecting rod also ensures mechanical stability during transmission, extending the service life of the transmission components.

[0011] Preferably, the lifting and adjusting assembly includes a fixing sleeve, which is fixedly connected to the right side of the connecting rod, and a metal rod is fixedly connected to the rear side of the LCD all-in-one machine, the metal rod being rotatably connected to the fixing sleeve.

[0012] Through the above technical solution, the lifting and adjusting assembly is fixedly connected to the connecting rod via a fixed sleeve, and the metal rod on the rear side of the LCD all-in-one display is rotatably connected to the fixed sleeve. This structural design ensures that the connecting rod drives the fixed sleeve to move synchronously to achieve the lifting and lowering of the LCD all-in-one display. At the same time, the rotational cooperation between the metal rod and the fixed sleeve allows the LCD all-in-one display to be finely adjusted according to actual usage needs during the lifting and lowering process, improving user comfort. Meanwhile, the fixed connection between the fixed sleeve and the connecting rod, as well as the fixed connection between the metal rod and the LCD all-in-one display, ensures the structural stability during the lifting and adjusting process, avoids adjustment failures caused by loose connections, simplifies the overall structure of the lifting and adjusting assembly, and reduces production and maintenance costs.

[0013] Preferably, slide rods are fixedly connected to both sides of the top of the fixing frame, and limit rings are slidably connected to the surface of the slide rods, and the limit rings are fixedly connected to the surface of the LCD all-in-one machine.

[0014] Through the above technical solution, the sliding rods on both sides of the top of the fixed frame are slidably connected to the limiting rings on the surface of the LCD all-in-one display, forming a guide and limiting structure during the lifting and lowering process of the LCD all-in-one display. This effectively limits the horizontal displacement of the LCD all-in-one display during the lifting and lowering process, ensuring that the LCD all-in-one display always lifts and lowers smoothly along the axis of the sliding rods. This avoids equipment damage or inconvenience caused by deviation during adjustment. The sliding cooperation between the sliding rods and the limiting rings also reduces the friction during the lifting and lowering process of the LCD all-in-one display, making the adjustment operation smoother and less strenuous. At the same time, the symmetrically arranged sliding rods and limiting rings on both sides further improve the balance performance of the LCD all-in-one display during lifting and lowering, enhancing the overall structural stability and safety of the equipment.

[0015] Preferably, a positioning frame is fixedly connected to the outer side of the limiting ring, and a locking rod is slidably connected inside the positioning frame. The surface of the sliding rod is provided with a locking groove for engaging with the locking rod.

[0016] Through the above technical solution, the positioning frame on the outside of the limiting ring is slidably connected to the locking rod. The sliding rod surface has a locking groove for engaging with the locking rod. This structure can fix the LCD all-in-one machine after it is adjusted to the target height by engaging with the locking rod and the locking groove, effectively preventing the height deviation of the LCD all-in-one machine due to vibration or accidental contact during use, further improving the stability and safety of the equipment during use. The detachable locking method of the locking rod and the locking groove also makes it easy to readjust the height according to the usage needs, making the operation convenient and efficient. The setting of multiple locking grooves can realize multiple height fixation levels, enriching the height adjustment levels of the equipment and adapting to more usage scenarios. The sliding limit of the positioning frame on the locking rod ensures the accuracy and reliability of the locking process, avoiding fixation failure caused by locking rod deviation.

[0017] Preferably, a spring is fixedly connected to the surface of the lever, and the outer side of the spring is fixedly connected to the surface of the positioning frame.

[0018] Through the above technical solution, the spring is fixed to the surface of the positioning frame via a fixed connection on the surface of the locking rod. The elastic force of the spring can always generate a preload force on the locking rod in the direction of the sliding rod, ensuring that the locking rod can be stably locked in the slot when no external force is applied. This avoids the locking rod from disengaging from the slot due to vibration or other factors, thus improving the reliability of the locking and fixing. At the same time, when it is necessary to adjust the height of the LCD all-in-one machine, only external force needs to be applied to make the locking rod overcome the spring force and disengage from the slot for adjustment. After adjustment, the spring can automatically push the locking rod back to lock in place. The operation is simple and quick, without the need for additional fixing parts, simplifying the operation process. The buffering effect of the spring can also reduce the impact force when the locking rod and the slot are locked in place, avoid component wear, and extend the service life of the locking rod and the slot.

[0019] Preferably, a support ring is rotatably connected to the left side of the worm gear, and the bottom of the support ring is fixedly connected to the top of the fixing frame.

[0020] Through the above technical solution, the bottom of the support ring, which is rotatably connected to the left side of the worm gear, is fixed to the top of the fixed frame. This limiting structure provides an additional support point for the worm gear, effectively limiting the axial displacement and radial sway of the worm gear during rotation. This ensures that the worm gear and worm wheel always maintain stable meshing, avoiding transmission failures or reduced transmission efficiency caused by worm gear misalignment. It improves the operational stability and reliability of the transmission components. At the same time, the fixed connection between the limiting ring and the fixed frame ensures the robustness of the support structure and prevents loosening due to long-term rotation of the worm gear, further extending the service life of the transmission components and ensuring the long-term stable operation of the entire height adjustment system.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model achieves precise and stable height adjustment of an all-in-one LCD display by using a servo motor and a worm gear transmission structure. The excellent self-locking performance of the worm gear, combined with the locking and fixing design of the lever and slot, effectively avoids accidental displacement caused by external forces and vibrations during adjustment and use, significantly improving the accuracy and stability of the equipment height adjustment. At the same time, the guide and limiting structure composed of the slide rod and the limiting ring ensures that the all-in-one LCD display always rises and falls smoothly along a fixed trajectory, avoiding deviation and damage. Combined with the supporting and limiting function of the limiting ring on the left side of the worm gear, it ensures the long-term stable meshing operation of the transmission components, significantly enhancing the overall structural reliability and service life of the equipment.

[0023] 2. This utility model simplifies the height adjustment process by using a spring design on the surface of the locking rod, eliminating the need for additional fixing components. It also reduces wear on the locking rod and the locking slot through a buffering effect, thus lowering maintenance costs. The multi-position locking slot design enriches the height adjustment range, adapting to different usage scenarios. The simplified design of the overall structure further reduces manufacturing costs and improves the practicality and market adaptability of the equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 A liftable LCD display all-in-one machine includes an LCD display all-in-one machine 1, a fixed frame 2 is fixedly connected to the bottom of the LCD display all-in-one machine 1, a limit plate 3 is fixedly connected to the rear side of the top of the fixed frame 2, a transmission component 4 is provided inside the limit plate 3, and a lifting adjustment component 5 is provided on the rear side of the LCD display all-in-one machine 1.

[0031] Transmission component 4 is used to drive the lifting adjustment component 5;

[0032] The height adjustment component 5 is used to adjust the height of the LCD all-in-one machine 1.

[0033] Please see Figure 4 The transmission assembly 4 includes a rotating rod 41, which is rotatably connected inside the limiting plate 3. A connecting rod 42 is fixedly connected to the surface of the rotating rod 41, and a worm gear 43 is fixedly connected to the surface of the rotating rod 41. A worm 44 is meshed at the top of the worm gear 43, and a servo motor 45 is driven to the right side of the worm 44.

[0034] Furthermore, the transmission assembly 4 employs a combination structure of a rotating rod 41, a connecting rod 42, a worm gear 43, a worm 44, and a servo motor 45. The servo motor 45 drives the worm 44 to rotate, and the meshing transmission between the worm gear 43 and the worm 44 drives the rotating rod 41 to rotate, thereby causing the connecting rod 42 to move synchronously. This transmission method features precise transmission ratio, smooth operation, and excellent self-locking performance, effectively preventing accidental displacement caused by external forces during adjustment. At the same time, the precise control of the servo motor 45 enables fine adjustment of the height of the LCD all-in-one machine 1, meeting the precise height requirements of different usage scenarios. The fixed connection between the rotating rod 41 and the connecting rod 42 also ensures mechanical stability during transmission and extends the service life of the transmission assembly 4.

[0035] Please see Figure 4 The lifting adjustment component 5 includes a fixed sleeve 51, which is fixedly connected to the right side of the connecting rod 42. A metal rod 52 is fixedly connected to the rear side of the LCD all-in-one machine 1, and the metal rod 52 is rotatably connected to the fixed sleeve 51.

[0036] Furthermore, the lifting adjustment component 5 is fixedly connected to the connecting rod 42 via the fixed sleeve 51, and the metal rod 52 on the rear side of the LCD all-in-one machine 1 is rotatably connected to the fixed sleeve 51. This structural design ensures that the connecting rod 42 drives the fixed sleeve 51 to move synchronously to achieve the lifting and lowering of the LCD all-in-one machine 1. At the same time, the rotational cooperation between the metal rod 52 and the fixed sleeve 51 allows the LCD all-in-one machine 1 to finely adjust its angle according to actual usage needs during the lifting and lowering process, improving the comfort of use. Meanwhile, the fixed connection between the fixed sleeve 51 and the connecting rod 42, as well as the fixed connection between the metal rod 52 and the LCD all-in-one machine 1, ensures the structural stability during the lifting and adjusting process, avoids adjustment failures caused by loose connections, simplifies the overall structure of the lifting adjustment component 5, and reduces production and maintenance costs.

[0037] Please see Figure 3 Both sides of the top of the fixed frame 2 are fixedly connected to slide rods 6, and limit rings 7 are slidably connected to the surface of the slide rods 6. The limit rings 7 are fixedly connected to the surface of the LCD all-in-one machine 1.

[0038] Furthermore, the sliding rods 6 on both sides of the top of the fixed frame 2 are slidably connected to the limiting rings 7 on the surface of the LCD all-in-one machine 1, forming a guide and limiting structure for the lifting and lowering process of the LCD all-in-one machine 1. This effectively limits the horizontal displacement of the LCD all-in-one machine 1 during the lifting and lowering process, ensuring that the LCD all-in-one machine 1 always lifts and lowers smoothly along the axis of the sliding rods 6. This avoids equipment damage or inconvenience caused by deviation during adjustment. The sliding cooperation between the sliding rods 6 and the limiting rings 7 also reduces the friction during the lifting and lowering process of the LCD all-in-one machine 1, making the adjustment operation smoother and less strenuous. At the same time, the symmetrically arranged sliding rods 6 and limiting rings 7 on both sides further improve the balance performance of the LCD all-in-one machine 1 during lifting and lowering, enhancing the overall structural stability and safety of the equipment.

[0039] Please see Figure 3 The outer side of the limiting ring 7 is fixedly connected to the positioning frame 8, and the inside of the positioning frame 8 is slidably connected to the locking rod 9. The surface of the sliding rod 6 is provided with a locking groove 10 that engages with the locking rod 9.

[0040] Furthermore, the positioning frame 8 on the outside of the limiting ring 7 is slidably connected to the locking rod 9. The surface of the sliding rod 6 has a locking groove 10 that engages with the locking rod 9. This structure allows the LCD all-in-one machine 1 to be fixedly limited after it is adjusted to the target height by engaging the locking rod 9 with the locking groove 10. This effectively prevents the height deviation of the LCD all-in-one machine 1 due to vibration or accidental contact during use, further improving the stability and safety of the equipment during use. The detachable locking method of the locking rod 9 and the locking groove 10 also makes it easy to readjust the height according to usage needs. The operation is convenient and efficient. The setting of multiple locking grooves 10 can realize multiple height fixation levels, enriching the height adjustment levels of the equipment and adapting to more usage scenarios. The sliding limit of the positioning frame 8 on the locking rod 9 ensures the accuracy and reliability of the locking process and avoids the fixation failure caused by the deviation of the locking rod 9.

[0041] Please see Figure 3 A spring 11 is fixedly connected to the surface of the lever 9, and the outer side of the spring 11 is fixedly connected to the surface of the positioning frame 8.

[0042] Furthermore, the spring 11, which is fixedly connected to the surface of the locking rod 9, is fixed to the surface of the positioning frame 8. The elastic force of the spring 11 can always generate a preload force on the locking rod 9 in the direction of the slide rod 6, ensuring that the locking rod 9 can be stably locked in the slot 10 when there is no external force. This avoids the locking rod 9 from disengaging from the slot 10 due to vibration or other factors, thus improving the reliability of the locking and fixing. At the same time, when it is necessary to adjust the height of the LCD all-in-one machine 1, it is only necessary to apply external force to make the locking rod 9 overcome the elastic force of the spring 11 and disengage from the slot 10 for adjustment. After the adjustment is completed, the spring 11 can automatically push the locking rod 9 to reset and lock in place. The operation is simple and quick, without the need for additional fixing parts, which simplifies the operation process. The buffering effect of the spring 11 can also reduce the impact force when the locking rod 9 and the slot 10 are locked in place, avoid component wear, and extend the service life of the locking rod 9 and the slot 10.

[0043] Please see Figure 4 The left side of the worm gear 44 is rotatably connected to a support ring 12, and the bottom of the support ring 12 is fixedly connected to the top of the fixed frame 2.

[0044] Furthermore, the bottom of the support ring 12, which is rotatably connected to the left side of the worm 44, is fixed to the top of the fixed frame 2. This limiting structure provides an additional support point for the worm 44, effectively limiting the axial displacement and radial swing of the worm 44 during rotation. This ensures that the worm 44 and the worm wheel 43 always maintain stable meshing, avoiding transmission failure or reduced transmission efficiency caused by the offset of the worm 44. This improves the operational stability and reliability of the transmission assembly 4. At the same time, the fixed connection between the limiting ring 7 and the fixed frame 2 ensures the robustness of the support structure and prevents loosening due to the long-term rotation of the worm 44. This further extends the service life of the transmission assembly 4 and ensures the long-term stable operation of the entire height adjustment system.

[0045] The specific implementation process of this utility model is as follows: The servo motor 45 is started, driving the worm gear 44 to rotate. The worm gear 44 meshes with the worm wheel 43 on the surface of the rotating rod 41, causing the rotating rod 41 to rotate within the limiting plate 3. This causes the connecting rod 42 on the rotating rod 41 to swing synchronously. The connecting rod 42 is rotatably connected to the metal rod 52 on the rear side of the LCD all-in-one machine 1 through the fixing sleeve 51, thereby pushing the LCD all-in-one machine 1 to smoothly rise and fall along the sliding rods 6 on both sides of the top of the fixing frame 2. The locking rod 9 is subjected to force, which is greater than the elastic force of the surface spring 11, causing the inner end of the locking rod 9 to disengage from the locking groove 10 on the surface of the sliding rod 6, releasing the height lock on the LCD all-in-one machine 1. During this process, the support ring 12 rotatably connected to the left side of the worm gear 44... The worm gear 44 provides support and limits, ensuring stable meshing between the worm gear 44 and the worm wheel 43. Simultaneously, the slide bar 6 slides against the limiting ring 7 on the surface of the LCD all-in-one unit 1, limiting the horizontal displacement of the LCD all-in-one unit 1 and ensuring smooth lifting. When the LCD all-in-one unit 1 reaches the target height, the user stops the servo motor 45, and the locking rod 9 automatically resets under the preload of the spring 11, locking into the corresponding slot 10 of the slide bar 6, thus firmly fixing the LCD all-in-one unit 1 at that height. The entire process, through the precise transmission of the transmission component 4, the fine-tuning of the angle of the lifting adjustment component 5, the smooth guidance of the guide and limiting structure, and the reliable locking of the positioning component, together achieves precise and safe adjustment of the height of the LCD all-in-one unit 1.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
