Description

Technical Field

[0001] The utility model belongs to the technical field of LED floor screens, and in particular relates to a wear-resistant LED floor screen. Background Art

[0002] In today's era of rapid technological development, LED displays, as an important information display device, have been widely used in various fields. Among them, LED floor screens, with their unique display effects and interactivity, have become an important component in scenes such as stage performances, commercial displays, and outdoor advertising.

[0003] Traditional LED floor screens usually focus on improving display effects and resolution, but pay less attention to their shock absorption performance when subjected to external pressure. During stage performances, actors may dance or perform other movements on the LED floor screen. The position and strength of their steps are unpredictable, which can easily lead to unbalanced force on the LED floor screen and damage its internal protective electronic components and lamp beads. In commercial display areas, customers may accidentally step on a certain part of the LED floor screen, which will also cause damage to it.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the present invention proposes a wear-resistant LED floor screen to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a wear-resistant LED floor screen, comprising a shell, a floor screen is provided on the top of the shell, a connecting block is fixedly installed on the floor screen close to one end of the shell and located in the inner cavity of the shell, a buffer air bag is provided in the middle of the inner cavity of the shell, a plurality of buffer components are arranged in a circular array on the bottom of the connecting block, a connecting pipe is provided at one end of the buffer component, the other end of the connecting pipe is provided on the buffer air bag, the plurality of buffer air bags, the plurality of connecting pipes and the buffer components are connected, two pressure gauges are respectively provided on the connecting pipes, and a flow valve is provided on the connecting pipe and located between the two pressure gauges.

[0008] Furthermore, the housing includes a shell, a plurality of mounting grooves are provided on two adjacent sides of the bottom of the shell, and a plurality of mounting blocks are fixedly installed on the other two adjacent sides of the bottom of the shell.

[0009] Furthermore, the buffer assembly includes a connecting rod, which is fixedly mounted on the bottom of the connecting block, and an air cylinder is sleeved on the circumferential surface of the connecting rod.

[0010] Furthermore, a fixing plate is fixedly mounted on the circumferential surface of the connecting rod, a spring is fixedly mounted on one end of the fixing plate, and both the fixing plate and the spring are located in the air cylinder.

[0011] Furthermore, an isolation plate is fixedly mounted in the middle of the inner cavity of the air cylinder, one end of the spring is fixedly mounted on the fixed plate and the other end is fixedly mounted on the isolation plate.

[0012] Furthermore, a piston gasket is fixedly installed on the other end of the connecting rod, the isolation plate and the end of the cylinder cavity away from the connecting rod form a closed cylinder chamber, and the piston gasket is located in the cylinder chamber.

[0013] Furthermore, one end of the communicating tube is located in the cylinder chamber, and the cylinder chamber, the communicating tube and the buffer airbag are communicated with each other.

[0014] The utility model has the following beneficial effects:

[0015] 1. When external pressure acts on the four sides of the floor screen, the connecting block close to one end of the outer shell transmits the pressure to multiple buffer components. Elastic deformation occurs inside the buffer components and the elastic potential energy increases. At this time, the flow valve and the connecting pipe are closed, and the gas inside the buffer components will also be compressed. The floor screen is buffered by internal elastic deformation and gas compression. The upper and lower ends of the buffer airbag under the connecting block are compressed and contracted, and expand toward the four sides to also buffer the floor screen.

[0016] 2. In the present invention, when a heavier actor steps hard on a certain point of the floor screen, one side of the floor screen will be higher than the other side, which may easily damage the electronic components and lamp beads. The connecting pipe is connected to the buffer component, and the air pressure value can be detected by a pressure gauge. When the buffer component reaches the maximum buffering value, the flow valve draws the gas from other places into the buffer component on the side with excessive pressure through the connecting pipe, and the gas pushes the multiple buffer components on the pressurized side to push the floor screen in the direction of pressure, so that the floor screen remains horizontal. This process is repeated when the pressure is too high elsewhere. Multiple buffer components and buffer airbags can buffer the pressure of the floor screen, thereby reducing the risk of damage to electronic components and lamp beads due to unbalanced force, and improving the durability and reliability of the LED floor screen.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] See also Figures 1-6As shown, the utility model is a wear-resistant LED floor screen, comprising a shell 1, a floor screen 2 is provided on the top of the shell 1, the floor screen 2 is close to one end of the shell 1 and is fixedly installed with a connecting block 3 in the inner cavity of the shell 1, a buffer air bag 4 is provided in the middle of the inner cavity of the shell 1, and a plurality of buffer components 5 are arranged in a circular array at the bottom of the connecting block 3, a connecting pipe 6 is provided at one end of the buffer component 5, and the other end of the connecting pipe 6 is provided on the buffer air bag 4, and the plurality of buffer air bags 4, the plurality of connecting pipes 6 and the buffer components 5 are connected, and two pressure gauges 7 are respectively provided on the connecting pipe 6, and a flow valve 8 is provided on the connecting pipe 6 and located between the two pressure gauges 7.

[0030] Among them, the top of the floor screen 2 is coated with acrylic wear-resistant material, which has the following advantages and characteristics: high surface hardness, good wear resistance, excellent optical properties, high transparency, little impact on display effects, good weather resistance, and can remain stable under different climatic conditions. The main purpose is that in stage performances, the actors' dance moves may include sliding, spinning, stomping, etc. These movements will cause friction on the surface of the floor screen. The wear-resistant material can withstand these frictions, reduce scratches, wear pits and other damage to the surface of the floor screen due to frequent friction, and extend the service life of the floor screen.

[0031] First, when external pressure acts on the four sides of the floor screen 2, the connecting block 3 at one end of the floor screen 2 close to the outer shell 1 will transmit the pressure to the multiple buffer components 5 in the bottom circular array. After the multiple buffer components 5 are subjected to pressure, elastic deformation occurs inside the buffer component 5, and the elastic potential energy increases. At this time, the flow valve 8 is in a closed state, and the connecting pipe 6 is also in a closed state. At the same time, the gas inside the buffer component 5 will also be compressed by the pressure, and then the internal deformation of the buffer component 5 and the compression of the internal gas will buffer the pressure on the floor screen 2. Of course, the upper and lower ends of the buffer air bag 4 located under the connecting block 3 are compressed and contracted to expand around, thereby also buffering the floor screen 2.

[0032] Secondly, when a heavier actor steps on a certain point on the floor screen 2 with greater force, the floor screen 2 will be higher on one side and lower on the other side. The excessive force on one side of the floor screen 2 will cause damage to the electronic components and lamp beads. Since the connecting pipe 6 is connected to the buffer component 5, the air pressure value of the buffer component 5 can be detected by the pressure gauge 7. That is, when the buffering effect of the buffer component 5 reaches the maximum value, the flow valve 8 will draw the gas in the buffer air bag 4 and the buffer component 5 in the less pressurized area through the connecting pipe 6 to the buffer component 5 on the side with excessive pressure, so that the buffer component 5 on the side with excessive pressure increases the buffering of the floor screen 2, and the gas pushes the multiple buffer components 5 on the pressurized side to push the floor screen 2 in the direction of pressure, keeping the floor screen 2 in a horizontal position as a whole and maintaining it. When the pressure elsewhere on the floor screen 2 is too large, the above process will be repeated. The pressure on the floor screen 2 can be effectively buffered by multiple buffer components 5 and the buffer air bag 4.

[0033] Finally, when external pressure acts on the four sides of the floor screen 2, the connecting block 3 near one end of the outer shell 1 transmits the pressure to multiple buffer components 5. Elastic deformation occurs inside the buffer component 5 and the elastic potential energy increases. At this time, the flow valve 8 and the connecting pipe 6 are closed, and the gas inside the buffer component 5 will also be compressed. The floor screen 2 is buffered by internal elastic deformation and gas compression. The buffer airbag 4 under the connecting block 3 is compressed and contracted at the upper and lower ends and expands to the four sides to buffer the floor screen 2.

[0034] Therefore, when a heavier actor steps hard on a certain point of the floor screen 2, one side of the floor screen 2 will be higher than the other side, which may easily damage the electronic components and lamp beads. The connecting pipe 6 is connected to the buffer component 5, and the air pressure value can be detected by the pressure gauge 7. When the buffer component 5 reaches the maximum buffering value, the flow valve 8 draws the gas from other places into the buffer component 5 on the side with excessive pressure through the connecting pipe 6, and the gas pushes the multiple buffer components 5 on the pressurized side to push the floor screen 2 in the direction of pressure, so that the floor screen 2 remains horizontal. This process is repeated when the pressure is too high elsewhere. The multiple buffer components 5 and the buffer airbags 4 can buffer the pressure of the floor screen 2, thereby reducing the risk of damage to electronic components and lamp beads due to unbalanced force, and improving the durability and reliability of the LED floor screen.

[0035] In one embodiment, the housing 1 includes a shell 101 , a plurality of mounting grooves 102 are formed on two adjacent sides of the bottom of the shell 101 , and a plurality of mounting blocks 103 are fixedly mounted on the other two adjacent sides of the bottom of the shell 101 .

[0036] The design of the mounting groove 102 and the mounting block 103 is mainly used for connecting or assembling the shell 101 with the adjacent shell 101. The mounting block 103 is inserted into the corresponding mounting groove 102 to achieve stable installation and fixation between the shells 101 and 101 at a specific position.

[0037] In one embodiment, for the above-mentioned buffer assembly 5, the buffer assembly 5 includes a connecting rod 501, which is fixedly installed on the bottom of the connecting block 3, and an air cylinder 502 is sleeved on the circumferential surface of the connecting rod 501.

[0038] A fixing plate 503 is fixedly mounted on the circumferential surface of the connecting rod 501 , and a spring 504 is fixedly mounted on one end of the fixing plate 503 . Both the fixing plate 503 and the spring 504 are located in the air cylinder 502 .

[0039] An isolation plate 505 is fixedly mounted in the middle of the inner cavity of the gas cylinder 502 . One end of the spring 504 is fixedly mounted on the fixing plate 503 and the other end is fixedly mounted on the isolation plate 505 .

[0040] A piston gasket 506 is fixedly mounted on the other end of the connecting rod 501 , and the isolation plate 505 and the inner cavity of the gas cylinder 502 away from the end of the connecting rod 501 form a closed cylinder chamber 9 , and the piston gasket 506 is located in the cylinder chamber 9 .

[0041] When external pressure acts on the floor screen 2, the connecting block 3 transmits the pressure to the connecting rod 501. After being subjected to the force, the connecting rod 501 moves in the air cylinder 502, driving the fixed plate 503 to move, and then compressing the spring 504. The spring 504 undergoes elastic deformation, stores elastic potential energy, and plays a partial buffering role. At the same time, the connecting rod 501 drives the piston gasket 506 to move in the cylinder chamber 9, compressing the gas in the cylinder chamber 9. On the one hand, the isolation plate 505 fixes one end of the spring 504, and on the other hand, forms a closed cylinder chamber 9 with the end of the air cylinder 502 cavity away from the connecting rod 501, ensuring that the gas is compressed in the cylinder chamber 9. The elastic deformation of the spring 504 and the compression of the gas in the cylinder chamber 9 jointly provide a buffer for the floor screen 2, reducing the damage of external pressure to internal electronic components and lamp beads.

[0042] In one embodiment, for the connecting pipe 6 , one end of the connecting pipe 6 is located in the cylinder chamber 9 , and the cylinder chamber 9 , the connecting pipe 6 and the cushioning airbag 4 are connected.

[0043] When a heavier actor steps on a certain point on the floor screen 2 with greater force, the floor screen 2 will be higher on one side and lower on the other side. The excessive force on one side of the floor screen 2 will cause damage to the electronic components and lamp beads. Since the cylinder chamber 9 is connected to the buffer air bag 4, and the air pressure value in the cylinder chamber 9 is detected by the pressure gauge 7, when the buffering effect of the cylinder chamber 9 reaches the maximum value, the flow valve 8 will draw the gas in the buffer air bag 4 and the cylinder chamber 9 in the less pressurized area through the connecting pipe 6 to the cylinder chamber 9 on the side with excessive pressure, so that the cylinder chamber 9 on the side with excessive pressure increases the buffering of the floor screen 2, and the gas pushes the multiple cylinder chambers 9 on the pressurized side to push the floor screen 2 in the direction of pressure, keeping the floor screen 2 in a horizontal position as a whole and maintaining it, thereby reducing the risk of damage to electronic components and lamp beads due to unbalanced force, and improving the durability and reliability of the LED floor screen.
