Description

Technical Field

[0001] The present invention relates to a bracket, and more particularly to a multifunctional bracket of an electronic screen for teaching and conference. Background Art

[0002] Electronic screens for teaching and conferences are a modern educational aid that brings a vivid visual experience to the classroom through high-definition display technology. Such electronic screens usually integrate touch functions, which greatly improves the interactivity and fun of teaching. They support the display of multimedia content such as videos, pictures and documents, making the teaching content richer and more intuitive. In addition, electronic screens also have network connection functions, which can access online resources in real time, realize remote teaching and resource sharing. The widespread use of electronic screens for teaching and conferences is gradually changing the traditional teaching model and injecting new impetus into the development of educational informatization.

[0003] Electronic screens for teaching and conferences generally use floor-standing brackets. In general, floor-standing display screen brackets mostly use space rigid truss structures, and their basic support uses space grid structures, which are composed of four or more steel columns; the upper display screen part uses horizontal space multi-layer trusses, which not only ensures the overall stability and reliability of the bracket, but also allows the corresponding maintenance channels to be set up to facilitate the maintenance of the electronic display screen.

[0004] However, existing electronic screen brackets often have the following disadvantages and shortcomings.

[0005] First, it is difficult to adjust the height. Existing brackets often cannot be adjusted in height or can only be adjusted manually. In actual use, some brackets often have problems such as insufficient adjustment flexibility or requiring greater force to adjust. Especially for heavier display screens, the experience of adjusting the position is often not ideal.

[0006] Second, stable support is difficult. As mentioned above, existing brackets are often made of steel for stability, which is large and inconvenient to move. This means that the bracket needs to be disassembled when it is used in a new location or for maintenance. Although existing brackets often have moving wheels at the bottom, these wheels allow the entire bracket to be easily moved. And in some cases, these wheels may have braking functions, thereby fixing the bracket position. However, on a site with an uneven ground, the bracket still cannot be safely and stably supported.

[0007] Third, it is difficult to adjust the angle. Existing display screen stands that can adjust the angle are often only suitable for small and light electronic screens such as flat screens, tablet computers or flat-panel televisions. Its basic structure is a single-column rotating column plus a display screen bracket. This is obviously not applicable to large electronic display screens for teaching and conferences with a frame structure.

[0008] Fourth, it is difficult to transport and move. Although the existing display screen bracket is equipped with moving wheels, it is still difficult to carry it during the moving process due to its large size, so if the bracket needs to be moved, it is sometimes necessary to dismantle the bracket and reinstall it in another place.

[0009] Therefore, for electronic display screens for teaching and conferences that are large in size and heavy in weight, existing brackets have many problems, such as being unable to provide sufficient support or being difficult to adjust.

[0010] Therefore, there is an urgent need in the art for a multifunctional bracket for supporting an electronic display screen for teaching and conference. Summary of the invention

[0011] A brief summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceived aspects, and is neither intended to identify the key or critical elements of all aspects nor to define the scope of any or all aspects. Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description given later.

[0016] An adjustable support foot assembly is used to stabilize the multifunctional stand on the ground;

[0017] The lifting and lowering adjustment component, the angle adjustment component, the foldable component and the adjustable supporting foot component are operated manually and / or electrically.

[0018] According to a preferred embodiment of the present invention, the multifunctional bracket is also placed between the electronic screen and the writing board of the multifunctional bracket, and the writing board can be pulled out when needed.

[0019] According to a preferred embodiment of the present invention, the lifting and lowering adjustment component is realized by an electric push rod, an electric hydraulic component or an electric screw.

[0020] According to a preferred embodiment of the present invention, the angle adjustment assembly is implemented by a linkage mechanism or a hinge design.

[0021] According to a preferred embodiment of the present invention, the foldable assembly is realized by connecting a hinge, a telescopic rod and a folding piece.

[0022] According to a preferred embodiment of the present invention, the adjustable supporting foot assembly includes more than two adjustable supporting feet.

[0023] According to a preferred embodiment of the present invention, the electric mode includes: buttons, touch keys, remote controllers, and mobile phone APPs.

[0024] According to a preferred embodiment of the present invention, the two or more adjustable supporting feet are independently adjustable.

[0025] According to a preferred embodiment of the present invention, the multifunctional bracket further includes moving wheels.

[0026] According to a preferred embodiment of the present invention, the moving wheel and the adjustable supporting foot assembly are operated in an alternative manner.

[0036] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. This detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known components are shown in block diagram form in order to avoid diluting such concepts.

[0037] It is to be understood that other embodiments would be apparent based on the present disclosure, and that system, structural, process, or mechanical changes may be made without departing from the scope of the present disclosure.

[0038] Figure 1 The schematic structure of the currently common electronic display screen bracket 10 for teaching and conference is explained in FIG.

[0039] like Figure 1 As shown in , the bracket mainly includes the following components.

[0040] Display mounting plate: On the top of the bracket is a mounting plate for mounting the display. There are multiple holes on the plate for fixing displays of different sizes.

[0041] Vertical support rods: The display mounting plate is connected to the base at the bottom through two vertical support rods. These support rods can be telescopic to accommodate displays of different heights.

[0042] Base: At the bottom of the stand is a wide base that provides stability and prevents the display from tipping or falling over. The base is designed to support the weight of the entire stand and display.

[0043] Wheels 3: There are four wheels under the base, which allow the entire stand to be easily moved. In some cases, these wheels may have brakes to fix the stand in place.

[0044] As mentioned above, currently common brackets rely entirely on manual lifting and lowering adjustment. In actual use, the adjustment is often not flexible enough or requires a lot of force. Especially for heavier display screens, the experience of adjusting the position is often not ideal.

[0045] As shown in the figure, some brackets are equipped with moving wheels 3 on their bases, but the steel structure and the oversized size of the screen often result in a large volume, and it is still inconvenient to move. This may result in the bracket often needing to be disassembled and reinstalled at the new location when it is used in a new location or for maintenance. In some cases, these wheels may have a brake function, thereby fixing the bracket position. However, sometimes it is still not possible to safely and stably support the bracket, especially on bumpy and uneven ground.

[0046] In addition, the existing bracket 10 has no angle adjustment function, which causes users in different positions to be unable to see the content on the electronic screen due to light problems, affecting the teaching and meeting effects. The existing display screen brackets that can be adjusted in angle are often only suitable for small and light electronic screens such as flat screens, tablet computers or flat-panel televisions.

[0047] In order to solve the above problems, the present invention proposes a multifunctional electronic display screen bracket for teaching and conference.

[0048] Figure 2 2 is a front view illustrating the structure of an electronic display screen bracket 20 for teaching and conference according to an embodiment of the present invention.

[0049] like Figure 2 As shown in the figure, the bracket includes a bracket body 1, a moving wheel 3, a lifting and adjusting component 201, an adjustable support foot component 203, a removable writing board 204 and a foldable component 205. The lifting and adjusting component 201 drives a screw rod or a hydraulic component through a motor, thereby realizing automatic adjustment of the height of the display screen, reducing the need for manual operation. The figure only shows an example of a lifting rod.

[0050] As those skilled in the art can appreciate, the lifting and adjusting component 201 can be implemented in a variety of ways. To implement the lifting and adjusting component 201, such as but not limited to the following ways.

[0051] First, you can use an electric push rod. An electric push rod is a common electric lifting and adjustment component that converts rotary motion into linear motion through a motor-driven screw or gear to achieve the lifting and lowering of the bracket. This component can be integrated into the display bracket and controlled by buttons or remote controls.

[0052] Second, you can use an electro-hydraulic assembly. The electro-hydraulic assembly drives a hydraulic pump through an electric motor, which delivers hydraulic oil to the cylinder, pushing the piston up and down to achieve the lifting of the lifting platform. This assembly can provide smooth lifting and lowering movements and can carry larger loads.

[0053] Third, you can use an electric screw lift. The electric screw lift uses an electric motor as the power source, and realizes the lifting movement through the cooperation of the screw and the nut. This component has high precision and high stability, and is suitable for occasions where the lifting height needs to be precisely controlled.

[0054] Fourth, you can use an electric lifting column. The electric lifting column uses a built-in motor to drive a gear or screw structure to convert the motor's rotational motion into linear motion to achieve the lifting of the column. The control system can be a button or a remote control. Some high-end models also support memory functions and multi-stage height presets.

[0055] In addition, as a preferred embodiment, the electric lifting and adjusting component can also be provided with an obstacle-encountering retraction component and an overload protection component. That is, adding the obstacle-encountering retraction and overload protection functions to the electric lifting and adjusting component can further improve the safety of the component. When encountering an obstacle, the component will automatically stop and retract to avoid damage or injury to the electronic screen.

[0056] from Figure 2 As can be seen in the figure, the removable writing board 204 can be placed between the bracket 20 and the electronic screen to be used when the lecturer or conference host needs auxiliary explanation.

[0057] In addition, the moving wheels 3 and the adjustable support leg assembly 203 can be arranged in parallel. This ensures that the moving wheels can be used when moving, and the adjustable support leg assembly 203 can be used to provide more stable support when fixed, even in the case of uneven ground (for example, outdoor venues).

[0058] In addition, the multifunctional bracket can also be provided with a foldable component 205. The foldable component 205 can realize the folding function of the bracket to facilitate transportation or movement. The foldable component 205 can be implemented in a variety of ways. The following implementation methods are only examples and not limitations.

[0059] First, connected by hinges. The bracket can usually be composed of multiple connecting parts and support rods. The connecting parts can be hinges, buckles or buckles, so that the various parts of the bracket can move relative to each other.

[0060] Second, through the design of the telescopic rod. Some folding brackets can adopt a telescopic rod structure, and the bracket can be unfolded and folded by extending and retracting the telescopic rod.

[0061] Third, connection through folding pieces: In some multifunctional folding brackets, two bracket components are connected through folding pieces to achieve unfolding or folding.

[0062] By means of the foldable component 205, the multifunctional bracket can be folded for easy carrying when it is needed to be transported and moved. Generally speaking, a folding method can be adopted, that is, a hinge, a buckle or other structure is provided in the middle of the crossbeam to realize the connection between the upper and lower parts. When it is needed to be transported, the bracket can be folded into two halves, so as to facilitate movement and maintenance. Of course, if multiple folding is needed, it can also be realized and is included in the scope of the present invention.

[0063] Likewise, the foldable component 205 can also be controlled by means of the above control system, for example (but not limited to) the user pressing a button, touching a touch key, operating on a mobile phone APP, or using a remote controller in hand.

[0064] Figure 3 2 is a side view illustrating the structure of an electronic display screen bracket 20 for teaching and conference according to an embodiment of the present invention. Figure 3 The reference numerals in the figure are mostly the same as Figure 2 The same as in the figure, so it will not be described in detail. Different from it, the side view also shows an angle adjustment component 202. The angle adjustment component 202 can make the electronic screen realize left-right and front-back angle adjustment, so that the display screen can be tilted, rotated and swung to adapt to different viewing angles. The figure only shows an embodiment for front-back adjustment. By adjusting the different lengths of the supporting legs, the angle can be adjusted.

[0065] The following combination Figures 4 to 6 The detailed implementation process of the lifting adjustment component 201, the angle adjustment component 202 and the adjustable support foot component 203 of the present invention is described in detail.

[0066] By way of example and not limitation, Figure 4 A structure of the lifting and adjusting component 201 is explained in FIG. Figure 4As shown in , the assembly 201 may include a body 2011, a through hole is provided in the middle of the body, and a threaded rod 2012 may be provided in the through hole. The height adjustment of the bracket can be achieved by two adjustment mechanisms 2014 between the upper part of the body and the bottom of the threaded rod and the support plate 2013. For example, a threaded shape may be provided on the inner wall of the through hole of the body, and the latter may cooperate with the threaded rod 2012, so that the body 2011 can be lifted and lowered in a vertical direction. The adjustment mechanism 2014 may, for example, adopt a vertical lifting mechanism, which may, for example, drive the threaded rod 2012 to move up and down, so that the body 2011 can be lifted and lowered in a vertical direction.

[0067] The lifting and adjusting component may be integrated with a control system. The control system can ensure that the user can control the lifting and lowering of the lifting and adjusting component using buttons, touch keys, etc. Of course, the lifting and adjusting component can also be controlled by mobile applications and remote controls, making it more convenient for teachers or speakers to control the electronic screen.

[0068] Through these methods, the electric lifting and adjusting components can be effectively realized, thereby improving the convenience and safety of the display screen bracket.

[0069] In addition, the bracket 20 is also equipped with an angle adjustment component 202. The angle adjustment component 202 can adjust the angle of the electronic screen left and right, front and back, such as by using a connecting rod mechanism or hinge design, such as by using an electric drive, so that the display screen can be tilted, rotated and swung to adapt to different viewing angles. The angle adjustment component 202 can be implemented in a variety of ways. Figure 5 One of the embodiments is shown in FIG. For example, it may include a support foot and a frame-type support frame. A diagonal support leg with adjustable length can be set on the support frame. By adjusting the length of the diagonal support leg, different angles of the support plate can be achieved, thereby controlling the electronic screen to adjust different angles. For another example, an adjustable steel bracket can be designed, using an I-beam and a telescopic rod to achieve the purpose of angle adjustment.

[0070] Figure 5 FIG. 2 shows a structure of the angle adjustment component 202 of the electronic display screen bracket 20. Figure 5 As shown in , a card slot is provided in the base 2021, and the diagonal support leg 2022 can slide in the card slot to adjust the front and rear angle of the screen. Similarly, a card slot that slides left and right can be provided to achieve left and right angle rotation. Similarly, a spherical roller can be used to achieve 360-degree adjustment. These implementations are all included in the scope of the present invention.

[0071] As mentioned above, the operation of the angle adjustment function can also be completed with the help of a control system, such as buttons, touch keys, mobile phone APPs, and remote controls (but not limited to these), all of which are within the scope of the present invention.

[0072] In addition, in actual use scenarios, stability and safety are very critical considerations, especially in the case of uneven ground. In order to properly solve this problem, the multifunctional bracket of the present invention specifically involves an adjustable support foot assembly 203. Figure 6 One of the embodiments is shown in . This adjustable support foot assembly 203 has a unique structure, and it can be composed of at least two adjustable support feet. Each adjustable support foot here is independently adjustable, and this feature is of great significance. Imagine an outdoor place, where the ground is often bumpy and there are various ups and downs. And each adjustable support foot in this adjustable support foot assembly 203 can be independently adjusted according to different ground conditions. For example, some places are higher and some places are lower, and the adjustable support feet can be adjusted accordingly according to these differences, so that the bracket can be supported in a more stable and safe state.

[0073] Figure 6 The structural schematic diagram of the adjustable support foot assembly 203 of the electronic display screen bracket 20 is explained in FIG.

[0074] By way of example and not limitation, Figure 6 Three embodiments of adjustable support foot assemblies are shown in FIG. Figure 6 As shown in , the support leg assembly may include: a base 2031; three support legs 2032, the three support legs are rotatably arranged on the base, and the three support legs can be rotated outwardly to open or rotated inwardly to close along the connection between the three support legs and the base;

[0075] It also includes one or more positioning mechanisms, which are arranged between the base and the supporting legs and are used to position and adjust the opening angle of the supporting legs.

[0076] However, this is only an example, and those skilled in the art can easily understand that as long as there are more than two adjustable supporting feet, the solution of the present invention can be implemented, so these situations are included in the scope of the present invention.

[0077] In the preferred embodiment, the multifunctional bracket 20 also retains the design of installing the moving wheels 3. This design is very clever. When the multifunctional bracket needs to be moved, the moving wheels 3 can be put down and the moving operation can be easily performed using the moving wheels. When the multifunctional bracket reaches the designated position and needs to be fixed, the adjustable support foot assembly can be put down to allow the adjustable support foot assembly to play its role of stable support, ensuring the safety and stability of the bracket.

[0078] Of course, similarly, the above adjustment can also be achieved electrically, including but not limited to: buttons, touch keys, mobile phone APP, remote control, etc.

[0079] As a preferred embodiment, the bracket of the present invention can also be provided with a position for placing a removable writing board 204, which can be placed between the electronic screen and the frame bracket. When not in use, it can be stored behind the electronic screen, so that it neither affects viewing nor takes up space. When the teacher or conference host needs to provide auxiliary explanations or explanations, the writing board 204 can be pulled out to provide auxiliary teaching and explanations.

[0080] Therefore, the electronic screen stand for teaching and conference of the present invention can not only realize automatic height adjustment, thereby avoiding the inconvenience of manual adjustment, but also can adjust different angles of the electronic screen according to different positions of light and viewers, thereby realizing a good teaching and conference experience. In addition, the stand also has a folding function, which makes it easy to fold and carry the stand during maintenance, long-term non-use and movement, thereby saving space and labor costs.
