Description

Technical Field

[0001] This utility model relates to a sports field projection device, specifically a multi-purpose virtual sports field. Background Technology

[0002] Currently, there is a severe shortage of sports training venues, which greatly affects the needs of young people and sports enthusiasts. In particular, the requirements of middle and high schools are even higher, because a school in a big city usually cannot provide a variety of courts. Apart from football and basketball, other interest-type courts are lacking, such as tennis, volleyball, badminton, and the recently popular peak courts.

[0003] It is difficult to convert an existing sports field into a field for another type of ball game. Demolishing the old field and converting it into a field for another type of ball game is more time-consuming, labor-intensive, and expensive than building a new one. It will also cause disappointment and dissatisfaction among athletes who have used the field before, as they will lose their long-term training venue.

[0004] Furthermore, some courts use different lines on the ground to distinguish the court areas, resulting in complex and confusing court layouts that greatly affect usability.

[0005] In conclusion, there is a need to design a new type of sports field that can flexibly switch between multiple sports fields without causing confusion, in order to meet the needs of various athletes and improve the utilization efficiency of sports fields. Utility Model Content

[0006] To solve the aforementioned technical problems, the technical solution adopted by this utility model is to provide a multi-purpose virtual sports field, including multiple lights and supports installed in open spaces or venues, and a controller for controlling the switching of multiple sets of lights.

[0007] The lamp body is a projection lamp that can be rotatably suspended above an open space or stadium. The bracket is connected between the lamp body and the suspension point. It also includes multiple motor groups. The controller is connected to the motor groups. The motor groups are connected to the lamp body and the bracket one by one. The controller selects and controls the lamp body to move its light to the target position in the open space or stadium so that its light can map the field lines of stadiums of different shapes and types.

[0008] Alternatively, the light body may be an LED light that is built into or mounted on the ground above an open space or stadium. The bracket may be buried or erected between the bottom of the light body and the ground. The controller is connected to the light body and controls the light body to emit light as needed according to the specific location, so that its light can be displayed as field lines of different shapes and types of stadiums.

[0009] In the above scheme, when the lamp body is arranged in an open space or diagonally above the venue, it projects at an angle of 30° to 60° with the horizontal line.

[0011] In the above scheme, when the lamp body is arranged directly above an open space or venue, it projects onto a surface perpendicular to the open space or venue.

[0012] In the above scheme, when the lamp body is an LED lamp built into the ground of an open space or venue, the open space or venue is provided with a groove to accommodate the lamp body.

[0013] In the above scheme, when the lamp body is an LED lamp built into the ground or mounted on a raised platform above the ground of an open space or venue, the LED lamp is an LED tempered transparent screen.

[0014] In the above scheme, when the lamp body is an LED lamp built into the ground or mounted on the ground above the open space or venue, a square LED lamp is installed at the intersection of the two lamp body lines, and the square LED lamp is connected to two sets of controllers at the same time.

[0015] In the above scheme, the controller includes a microcontroller control circuit and a relay control circuit. The output terminal of the microcontroller control circuit is connected to the relay control circuit, and the microcontroller control circuit controls the switching of multiple sets of lamp wires through the relay control circuit.

[0016] In the above scheme, when the lamp body is an LED lamp built into the ground or mounted on an open space or venue, the LED lamp is a light strip composed of multiple lamp bodies connected in series.

[0017] In the above scheme, the controller and motor assembly are either built into or externally mounted on the bracket.

[0018] In the above scheme, the different types of stadiums are badminton stadiums, basketball stadiums, tennis stadiums, table tennis stadiums, volleyball stadiums, peaket stadiums, football stadiums, or hockey stadiums.

[0019] This invention allows a sports field to be quickly transformed into a field for another type of ball game, or a large sports field to be transformed into several smaller fields of another type, thus greatly satisfying the needs of various athletes at the same time. Moreover, it can be changed at any time according to the popular or trending ball games on the market, saving a lot of money and space required for expanding sports fields.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] It should be noted that in the description of this utility model, the terms "first" and "second" are used only for the convenience of describing different components and should not be construed as indicating or implying a sequential relationship, relative importance, or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0032] like Figures 1 to 5 As shown, this utility model provides a multi-purpose virtual sports field, including multiple light fixtures 1 and supports 2 installed in open spaces or venues, and a controller for controlling the switching of multiple sets of light wires. The controller includes a microcontroller control circuit and a relay control circuit. The output of the microcontroller control circuit is connected to the relay control circuit, and the microcontroller control circuit controls the switching of multiple sets of light fixtures or light wires through the relay control circuit. Preferably, the controller and motor assembly are built into or externally mounted on the supports 2.

[0033] Preferably, the controller includes a microcontroller control circuit and a relay control circuit. The output of the microcontroller control circuit is connected to the relay control circuit, and the microcontroller control circuit controls the switching of multiple sets of lamp wires through the relay control circuit. The controller and motor assembly are either built into or externally mounted on bracket 2.

[0034] like Figures 1 to 3 As shown, the lamp body 1 is a projection lamp that can be rotatably suspended above an open space or stadium. The bracket 2 is connected between the lamp body 1 and the suspension point. It also includes multiple motor units. The controller is connected to the motor units. The motor units are connected to the lamp body 1 and the bracket 2 respectively. The controller selects and controls the lamp body 1 to move its light to the target position in the open space or stadium, so that its light can map the field lines of different shapes and types of stadiums.

[0035] Among them, stadiums of different shapes and types can be badminton stadiums, basketball stadiums, tennis stadiums, table tennis stadiums, volleyball stadiums, peaket stadiums, football stadiums, or hockey stadiums.

[0036] like Figure 1 As shown, taking a badminton court as an example, when the light 1 is placed directly above the open space or the venue, it projects perpendicular to the open space or the venue, requiring a large number of light 1s.

[0037] like Figure 2 As shown, taking a badminton court as an example, when light fixture 1 is placed in an open space or diagonally above the venue, it projects light at an angle of 30° to 60° to the horizontal line. In this case, only a small number of lights are needed, such as... Figure 3 As shown, at this time, the lamp body 1 can be placed on the roof next to an open space or venue to provide oblique illumination, so that it can also be used around home venues.

[0038] This invention utilizes projection laser lights to project the lines of each type of sports field onto the ground. Based on the size, location, and height of each field, the required number, shape, and coverage area of ​​the projection lights are calculated. Multiple projection lights are installed in a single group, each controlled by an independent fixed switch. Each type of ball sport has its own independent group of projection lights and switch. This allows for switching between groups simply by turning one group off and another on simultaneously, essentially in real-time.

[0039] The parameters of the projection lamp's power, projection distance, and area in this invention are as follows (for reference only):

[0040] Power: The greater the power, the farther the projection distance.

[0041] Environment: In a dark environment, the projection distance of the projector will be farther.

[0042] Coverage area formula: Projection distance × 0.5 = circle diameter length.

[0043] Under different court sizes, heights, and environments:

[0044] A 200W projector lamp, under normal conditions, can project a distance of approximately 15 meters, resulting in a circle with a diameter of 7.5 meters.

[0045] A 300W projector lamp, under normal conditions, can project a distance of approximately 20 meters, resulting in a circle with a diameter of 10 meters.

[0046] A 600W projector lamp can project a distance of about 50 meters under normal conditions, with a diameter of 25 meters.

[0047] like Figures 4 to 5 As shown, the light body 1 is an LED light that is built into or mounted above the ground of an open space or stadium. The bracket 2 is buried or mounted between the bottom of the light body 1 and the ground to form a floor screen. The controller is connected to the light body 1 and controls the light body 1 to light up or not light up as needed according to the specific location, so that the light can be displayed as field lines of different shapes and types of stadiums. Using LED lights with lines hidden in the grooves under the floor, each type of ball field is equipped with a set of LED lights, which are connected to an independent switch for control. When the lights are on, they are clearly visible, while other light groups that are not lit are not visible on the ground.

[0048] like Figures 4 to 5As shown, when the light body 1 is an LED light built into the ground or mounted above the open space or stadium, the LED light is a light strip composed of multiple light bodies connected in series. The open space or stadium has a recess 3 to accommodate the light body 1, and the LED light is an LED tempered transparent screen. Note that the lines of many different types of ball courts need to be installed at intersections, so there will be some gaps. The solution is to install a 5mm square LED light 4 (equal to the width of the line) at the intersection of two lines. This LED light 4 can be controlled by two sets of power supplies simultaneously, and the square LED light 4 is connected to two sets of controllers at the same time.

[0049] This invention utilizes "light" to replace the existing fixed white paint lines on the sports field, achieving an effect that can be modified at any time. The "light" can be the second-generation LED line projection light and ground-buried lights that are already technically mature, as well as laser light and patterns projected by a laser machine.

[0050] like Figures 1 to 2 As shown, lamp 1 is a rotatable projection lamp suspended above an open area or stadium. It's important to note that when the projection lamp shines on certain locations, it may cast shadows of players, potentially affecting the referee's judgment of whether a ball is out of bounds or over. There are two solutions. One is to use two sets of overlapping projection lamps projecting from different angles onto key lines simultaneously. This avoids brief moments when the lines are not visible. Because projection lamps are inexpensive, the number of lamps shouldn't significantly impact the overall budget, especially outside of official matches. This situation is rare, as a person's shadow only covers a small portion of a long line, and it has little impact on experienced referees or other players. The other method is to install the projection lamps directly above the field, requiring more lamps to minimize the shadow area.

[0051] like Figures 7 to 10 The diagram illustrates application scenarios of this utility model, showing how a basketball court can simultaneously illuminate two tennis courts, six peak courts, and three volleyball courts, as well as how a basketball court can simultaneously illuminate one tennis court, one peak court, and one badminton court. Other types will not be listed here.

[0052] Beneficial effects of this utility model

[0053] (a) Save money, space and land for building new stadiums, and strive to provide more venues and services for ball sports training for some schools and communities with poor economic conditions.

[0054] (ii) It can be used for multiple purposes without dismantling the old one, thus achieving the goal of environmental protection.

[0055] (iii) It can satisfy the different sports interests of many people in one stop.

[0056] (iv) It can accommodate many people at the same time. For example, a basketball court that is only for ten people can be turned into six table tennis courts for twenty-four people to use at the same time. The same basketball court can also be used by eight groups of table tennis players at the same time.

[0057] (v) Different courts can be added or removed quickly according to popular trends. For example, the field of pickle, which is now popular in many parts of the world, is very scarce in China. Some less popular courts, such as badminton courts, can be quickly transformed into pickle courts. The two are the same size (both are 13.4 meters x 6.1 meters), with only a slight change in the lines. It would be too wasteful to renovate them.

[0058] This invention allows a sports field to be quickly transformed into a field for another type of ball game, or a large sports field to be transformed into several smaller fields of another type, thus greatly satisfying the needs of various athletes at the same time. Moreover, it can be changed at any time according to the popular or trending ball games on the market, saving a lot of money and space required for expanding sports fields.

[0059] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
