Description

Technical Field

[0001] The present invention relates to the technical field of bulletin boards, and in particular to a sports event bulletin board and a method of using the same. Background Art

[0002] Sports event bulletin boards are displays specifically designed to display information related to sports events. Their design focuses on flexibility, space efficiency, portability, environmental adaptability, and efficient information updates. With the advancement of information technology, electronic display screens, touch screens, and online platforms are beginning to be used for event information management. However, existing solutions often suffer from limited functionality, high deployment costs, complex operations, and a lack of unified standards.

[0003] In the existing technology, for example, the mobile sports event notice board developed by Guangzhou Borun Sports is equipped with universal wheels and a foldable support plate, which supports 360° free movement and directional locking, facilitating flexible scheduling between different competition venues (such as track and field stadiums, basketball halls, and around swimming pools). After the equipment is in place, the wheels can be retracted manually or electrically to ensure that the base is firmly in contact with the ground, significantly improving the notice board's anti-overturning ability and safety in outdoor or crowded environments.

[0004] The above-mentioned products lack effective shielding structures, such as roofs or retractable eaves. Under continuous exposure to the sun, strong ultraviolet rays will not only accelerate the aging and fading of the screen casing and frame materials, but may also cause brightness attenuation, color shift, and even partial black screen, affecting the visual effect and long-term reliability, and reducing the service life of the equipment. Therefore, it is necessary to propose a sports event notice board and its use method. Summary of the Invention

DETAILED DESCRIPTION

[0049] The following is further described in detail through specific implementation methods:

[0050] Example 1, as attached Figure 1 As shown: A sports event notice board, including a frame 1, a screen is fixedly connected to the frame 1 with bolts, a shielding curtain 2 is installed on the top of the frame 1, and an extension component for extending the shielding curtain 2 is provided on the top of the frame 1; a horizontal frame 3 is fixedly connected to the top of the frame 1 with bolts, and the extension component includes a moving rod 4 and a movable frame symmetrically arranged on the top of the horizontal frame 3; the shielding curtain 2 is fixedly bonded to the moving rod 4, and the movable frame is used to drive the moving rod 4 to slide; when the movable frame is extended, the moving rod 4 is moved away from the horizontal frame 3, thereby extending the shielding curtain 2.

[0051] The horizontal frame 3 is provided with a driving component for driving the movable frame to extend; the movable frame is provided with an extension component for extending the shielding curtain 2 to both sides of the axis direction of the frame 1; the outer wall of the frame 1 is provided with a scraping component for cleaning the screen; the frame 1 is also provided with an adsorption component for increasing the stability of the frame 1.

[0052] The driving component is used to drive the extension component, the scraping component and the adsorption component to operate synchronously; when the driving component drives the movable frame to move, it synchronously drives the extension component to extend the shielding curtain 2 to both sides, and synchronously drives the scraping component to clean the screen, and synchronously drives the adsorption component to increase the stability of the frame 1.

[0053] Combine Figure 2 As shown, the driving assembly includes a controller and a rotating member 5. In this embodiment, the rotating member 5 is a servo motor; the controller is electrically connected to the rotating member 5, and the rotating member 5 is fixedly connected to the outer wall of the frame body 1 with bolts; the output shaft of the rotating member 5 is coaxially fixedly connected to the screw rod 6 through a coupling, and the screw rod 6 is symmetrically threaded with a slide 7; the thread directions of adjacent slides 7 are opposite, and the slides 7 are all slidably matched with the cross frame 3. In this embodiment, the sliding match between the slide 7 and the cross frame 3 can provide a limit for it, so that the slide 7 maintains a linear movement trajectory; the movable frame includes several upper connecting rods 8 and lower connecting rods 9, the middle parts of the upper connecting rods 8 and the lower connecting rods 9 are hinged to each other, and the two ends of adjacent upper connecting rods 8 and lower connecting rods 9 are hinged to each other; the lower connecting rods 9 near one end of the cross frame 3 are hinged to the cross frame 3, and the upper connecting rods 8 near one end of the slide 7 are hinged to the slide 7; the lower connecting rods 9 near one end of the moving rod 4 are slidably matched with the moving rod 4, and the upper connecting rods 8 near one end of the moving rod 4 are hinged to the moving rod 4.

[0054] Specifically, the controller starts the rotation of the rotating member 5, and the output shaft of the rotating member 5 drives the screw rod 6 to rotate synchronously. Due to the opposite screw thread directions of the symmetrical sliding blocks 7 on the screw rod 6, the two sliding blocks 7 move synchronously and oppositely along the axis of the screw rod 6 under the screw thread cooperation. When the sliding blocks 7 move, the end of the upper connecting rod 8 connected to the sliding blocks 7 moves with the sliding blocks 7, forcing the upper connecting rod 8 to rotate around the middle hinge point. At the same time, the lower connecting rod 9 expands outward around the hinge point with the horizontal frame 3 as the fixed fulcrum, and expands outward under the linkage of the middle hinge point, and pushes the moving rod 4 through the hinge, thereby driving the shielding curtain 2 to expand outward.

[0055] As shown in Figure 3 As shown in the drawings, the expansion assembly includes a plurality of support rods 10, which are symmetrically hinged to the top of the movable frame. The moving rod 4 and the horizontal frame 3 are both screw-fixedly connected with a limiting buckle 11. In this embodiment, the limiting buckle 11 provides a limit for the support rod 10, so that the support rod 10 moves along the axis direction of the moving rod 4 or the screw rod 6. The support rod 10 is in sliding cooperation with the limiting buckle 11, and the end of the support rod 10 away from the movable frame is fixedly bonded with the bottom of the shielding curtain 2. The end of the support rod 10 away from the movable frame is screw-fixedly connected with an inclined installation of a telescopic member, and the telescopic member is electrically connected with the controller. The output shaft of the telescopic member is fixedly bonded with the bottom of the shielding curtain 2.

[0056] Specifically, when the sliding blocks 7 move outward relative to the horizontal frame 3, the upper connecting rod 8 of the movable frame and the lower connecting rod 9 expand, the end of the upper connecting rod 8 close to the sliding blocks 7 moves outward with the sliding blocks 7, and the upper end of the hinged support rod 10 moves outward. At the same time, the end of the lower connecting rod 9 close to the moving rod 4 moves with the extension of the moving rod 4, and drives the lower end of the support rod 10 to move outward synchronously. At this time, the two ends of the support rod 10 slide along the limiting buckles 11 of the moving rod 4 and the horizontal frame 3 respectively, the limiting buckles 11 limit the radial deviation of the support rod 10 through the guiding action, so that the support rod 10 moves stably, and the end of the support rod 10 away from the movable frame pulls the shielding curtain 2 together, so that the shielding curtain 2 expands evenly along the two sides of the horizontal frame 3, so that the shielding curtain 2 becomes flat after being opened, reducing the accumulation of rainwater in rainy weather. After the support rod 10 extends outward, the telescopic member can extend the outer edge of the shielding curtain downward, so that the rainwater can flow outward, increasing the practicability of the device.

[0057] As shown in Figure 6 As shown in the drawings, the scraping assembly includes a cleaning brush 12 in sliding cooperation with the screen. In this embodiment, the cleaning brush 12 is made of sponge, and the sliding cooperation between the cleaning brush 12 and the screen enables the cleaning brush 12 to maintain a linear moving track and move stably. The screw rod 6 is coaxially fixedly connected with a rotating wheel 13 at both ends. The rotating wheel 13 is fixedly bonded with a pull wire on the outer wall. The end of the pull wire away from the rotating wheel 13 is fixedly sleeved with the outer wall of the cleaning brush 12.

[0058] Specifically, when the rotating member 5 drives the screw rod 6 to rotate, the rotating wheels 13 at both ends of the screw rod 6 rotate synchronously with the screw rod 6. Since one end of the pull wire is fixed to the outer wall of the rotating wheel 13, when the rotating wheel 13 rotates, the pull wire is wound or released (according to the rotating direction), and a pulling force is applied to the cleaning brush 12. The cleaning brush 12 slides along the screen under the traction of the pull wire. At this time, the cleaning brush 12 is in close contact with the screen, and the screen surface is scraped and cleaned during the sliding process. When the slide 7 moves to the maximum stroke, the cleaning brush 12 reaches the edge of the screen, and completes a scraping action. When the screw rod 6 reversely rotates to drive the rotating wheel 13 to wind the pull wire, the cleaning brush 12 returns to the initial position along the original path.

[0059] In combination Figure 4 and Figure 5 As shown in FIGS. 1, 2 and 3, the suction assembly includes a transmission cylinder 14 symmetrically and fixedly connected to the outer wall of the frame 1, and the inner wall of the transmission cylinder 14 is slidably connected with a movable plate 15. The movable plate 15 is fixedly connected with a push rod 16, and the end of the push rod 16 away from the movable plate 15 is fixedly connected with the outer wall of the slide 7. The side of the transmission cylinder 14 close to the push rod 16 is connected with an air inlet pipe and an air outlet pipe, and the connection part between the air inlet pipe and the air outlet pipe and the transmission cylinder 14 is connected with a first one-way valve. In the embodiment, the first one-way valve is used to guide the one-way flow of fluid, so that the fluid flows out from the air outlet pipe after entering the air inlet pipe. The bottom of the frame 1 is symmetrically and fixedly connected with a suction disc 17, and the end of the air inlet pipe away from the transmission cylinder 14 is connected with the inside of the suction disc 17, and the air outlet pipe is connected with the outside of the transmission cylinder 14. In some preferred embodiments, the air outlet pipe can be connected with the outer wall of the rotating member 5, and air flow is used to provide heat dissipation for the rotating member 5 when the rotating member 5 operates.

[0060] Specifically, when the slide 7 moves outwardly along the cross frame 3, the push rod 16 fixed to the outer wall of the slide 7 synchronously pushes the movable plate 15 to slide along the inner wall of the transmission cylinder 14. The side of the transmission cylinder 14 close to the push rod 16 forms a negative pressure, the one-way valve of the air outlet pipe is closed, and the one-way valve of the air inlet pipe is opened. The air in the suction disc 17 is sucked into the transmission cylinder 14 through the air inlet pipe, so that the vacuum adsorption force is generated in the suction disc 17, thereby increasing the installation stability of the frame 1. During the whole process, the reciprocating movement of the slide 7 is converted into the piston action of the movable plate 15 through the push rod 16, and the suction disc 17 is adsorbed to increase the fixing effect of the frame 1 by cooperating with the air flow control of the first one-way valve.

[0061] The cleaning brush 12 is also connected with a conveying assembly for water supply. The conveying assembly includes a storage barrel 18 (such as a water tank) for storing water, and a water pump 19 connected with the storage barrel 18 and the air outlet pipe of the transmission cylinder 14. Figure 7The input pipe and the output pipe are communicated with the inside of the storage barrel 18 and the cleaning brush 12 respectively.

[0062] Specifically, when the sliding seat 7 moves outwardly, the push rod 16 pushes the movable plate 15 to compress the space, and the space on the side of the transmission cylinder 14 away from the push rod 16 is compressed; at this time, the input pipe one-way valve is closed, the output pipe one-way valve is opened, and the water in the chamber is squeezed into the output pipe and delivered to the cleaning brush 12, and the water flows through the inside of the cleaning brush 12 to soak the sponge, so as to realize wet cleaning of the screen. During the whole process, the double-chamber design of the transmission cylinder 14 realizes the synchronous linkage of water absorption and water delivery and exhaust and adsorption through the reciprocating movement of the movable plate 15 and the control of the two groups of one-way valves, so that the cleaning brush 12 completes water replenishment during the scraping process.

[0063] The specific implementation process is as follows:

[0064] When the shielding curtain 2 needs to be unfolded, the servo motor (power 50W, rotating speed 1500rpm) is started by the controller, the lead screw 6 is driven to rotate through the shaft coupling, and the symmetrically distributed sliding seat 7 (moving speed 12mm / s) is driven to move in the opposite direction along the cross frame 3. The sliding seat 7 pushes the moving rod 4 outwardly through the upper link 8 and the lower link 9, and the moving rod 4 synchronously drives the shielding curtain 2 to expand outwardly along the frame body 1.

[0065] When the movable frame is unfolded, the middle hinge points of the upper link 8 and the lower link 9 rotate at an angular velocity of 15° / s, and drive the support rod 10 to slide along the sliding groove of the limiting buckle 11. The support rod 10 moves to both sides of the axis direction of the cross frame 3 respectively, and pulls the shielding curtain 2 to expand to both sides of the cross frame 3, so as to expand the shielding area of the shielding curtain 2.

[0066] When the lead screw 6 rotates, the two end wheels 13 synchronously wind / unwind the pull wire, and the cleaning brush 12 is pulled to slide along the screen, the single scraping time is 8 seconds, and the cleaning coverage is 100%. The transmission cylinder 14 reciprocates through the movable plate 15, absorbs water from the storage barrel 18 through the input pipe, and then delivers water to the cleaning brush 12 through the output pipe, the single water delivery amount is 30mL, and the humidity of the cleaning brush 12 is maintained at 60%-70%.

[0067] When the sliding seat 7 moves, the push rod 16 pushes the movable plate 15 to form a pressure difference of ±0.05MPa in the transmission cylinder 14, and the suction cups 17 generate adsorption force (the suction force of a single suction cup 17 is greater than or equal to 80N) through the air inlet pipe (the opening pressure of the one-way valve is 0.02MPa), so as to stably fix the frame body 1 to the mounting surface and keep the center of gravity of the frame body 1 stable when the shielding curtain 2 is expanded.

[0068] The embodiment realizes synchronous operation of multiple functions by the joint operation of multiple components, the linkage of each connecting rod mechanism and the support rod 10 to realize the expansion of the shielding curtain 2, the cooperation of the rotating wheel 13 to pull the cleaning brush 12 to complete the screen scraping, and the linkage of the transmission cylinder 14 to form the negative pressure suction cup 17 to realize the synchronous operation of multiple functions, which improves the efficiency by more than 40% compared with the traditional step-by-step operation; the mechanical linkage replaces multiple motor independent driving, and the comprehensive energy consumption is reduced by 35%, achieving the goal of high efficiency and low consumption.

[0070] The specific implementation process is as follows: the water collecting pipe collects rainwater, which is purified by the filter layer 19 of the storage barrel 18, realizing water resource recycling and reducing external water supply dependence; the filter layer 19 blocks impurities to prevent pipeline blockage and protect the conveying assembly; without additional power, the linkage with the main body improves environmental protection and reduces maintenance cost.

[0071] Embodiment 3, the difference from the above embodiment is that the outer wall of the frame 1 is also screw-fixedly connected with a light sensor, a raindrop sensor and a wind speed sensor, the controller is used to receive the light information emitted by the light sensor, the rainfall information emitted by the raindrop sensor and the wind speed information emitted by the wind speed sensor, and control the operation of the rotating part 5 based on the light information, the rainfall information and the wind speed information.

[0072] The specific implementation process is as follows: the controller adjusts the operation of the rotating part 5 according to the real-time monitoring of the environmental parameters by the sensors; the shielding curtain 2 is expanded to prevent sunburn in strong light, and the curtain is retracted to avoid danger in strong wind, realizing self-adaptive response; without manual intervention, the intelligent level of the equipment is improved, the operation and maintenance cost is reduced, and the safety and reliability of operation in outdoor environment are ensured through the cooperation of multiple sensors.

[0073] Embodiment 4, the difference from the above embodiment is that the screen also includes a highlight enhancement mode and an energy-saving eye protection mode, and the controller is used to control the screen to switch modes based on the light information.

[0074] The specific implementation process is as follows: the controller automatically switches the screen mode according to the data of the light sensor, and the energy-saving eye protection mode is enabled at night to reduce power consumption; the highlight enhancement mode is switched to in the daytime to ensure the display brightness and clarity. Through the adaptive adjustment of the double modes, the intelligent level of the equipment is improved, the manual intervention is reduced, the outdoor environment is adapted, the endurance is prolonged, and the practicality and reliability of the equipment in the variable environment are enhanced.

[0075] Example 5, unlike the above examples, further provides a method for using a sports event bulletin board, comprising the following steps:

[0076] S1, through the light sensor (installed on the top of the frame body 1, real-time monitoring of ambient light intensity, accuracy ± 20 lux, response time 50 ms, detection range 0-65535 lux), raindrop sensor (integrated in the edge of the shielding curtain 2, sensitivity adjustable, default threshold: raindrop density ≥5 drops / cm 2 ) and wind speed sensor (range 0-50 m / s, accuracy ± 0.5 m / s) real-time detection of ambient light information, rainfall information and wind speed information, and the collected information is transmitted to the controller.

[0077] S2, the controller receives the light information sent by the light sensor, and when it is identified that the light information is daytime, the screen is switched to high-brightness enhancement mode to display the event information in real time; when the light is identified as night, the screen is switched to energy-saving eye protection mode to display the next day's schedule.

[0078] S3, when the controller receives the rainfall information or strong light information exceeding the preset threshold, the rotating part 5 drives the lead screw 6 to rotate, so that the symmetrical sliding seat 7 moves towards each other; the sliding seat 7 moves to extend the movable frame, and then pushes the moving rod 4 to move away from the horizontal frame 3, so that the shielding curtain 2 is extended outward.

[0079] S4, while the movable frame is extended, the shielding curtain 2 is expanded to the both sides of the frame body 1 through the supporting rod 10 to increase the shielding area; and the output parameters of the rotating part 5 are controlled according to the real-time rainfall information or strong light information to match the shielding area under different rainfall information or strong light information. For example, the rainfall grading response is set as follows: when it is light rain (0.5-2.5 mm / h), the output power of the rotating part 5 is adjusted to 30W, the shielding curtain 2 is expanded by 50%, and the supporting rod 10 is extended by 15 cm; when it is moderate rain (2.5-10 mm / h), the output power of the rotating part 5 is 40W, the expansion is 80%, and the supporting rod 10 is extended by an angle of 25 cm; when it is heavy rain (≥10 mm / h), the power is set to 50W, the shielding curtain 2 is fully expanded, and the supporting rod 10 is extended by 30 cm.

[0080] S5, when the lead screw 6 rotates, the rotating wheel 13 is simultaneously driven to retract and release the pull wire, and the pull wire pulls the cleaning brush 12 to slide along the surface of the screen to clean the screen. In this embodiment, daily cleaning can be set to start automatically once a day at 3:00 am (no event period), the cleaning brush 12 cleans twice, and the water supply is 5mL / time; post-rain cleaning: start within 15 minutes after the rainfall stops, the cleaning brush 12 cleans 3 times; deep cleaning: start at 23:00 every day, alternating water supply 3 times, the cleaning brush 12 pressure increases to 15N (default 10N), which increases the efficiency of stubborn stain removal.

[0081] S6, when the sliding base 7 moves, the push rod 16 is pushed to drive the movable plate 15 in the transmission cylinder 14 to move, and the air in the suction cup 17 is extracted through the air inlet pipe to form a negative pressure adsorption, so as to enhance the installation stability of the frame body 1. In the embodiment, the negative pressure is maintained at-0.06MPa to-0.08MPa during normal adsorption, and the suction cup 17 is started to adsorb when the shielding curtain 2 is extended.

[0082] S7, the movable plate 15 moves at the same time, and the water in the storage barrel 18 is pumped into the transmission cylinder 14 through the input pipe, and then delivered to the cleaning brush 12 through the output pipe.

[0083] Obviously, the above embodiment is only an example for clear illustration, and is not a limitation on the implementation. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the implementations are not required and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
