Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for track and field events, and in particular to an intelligent track and field lane bollard. Background Technology

[0002] In track and field event organization and daily training, lane markers are key auxiliary equipment used to mark track numbers, demarcate competition areas, and guide athletes to their positions. Currently, most lane markers used in track and field events and training at home and abroad are fixed plastic or metal shell structures, which only achieve lane marking functions by printing numbers and spraying colors. Their overall functions are simple and their level of intelligence is low.

[0003] Existing traditional track piers have several shortcomings that make them unsuitable for the needs of modern track and field events: Firstly, they suffer from poor structural stability and significant safety hazards. They are mostly cylindrical or simple block shapes with small base support areas and high centers of gravity, resulting in weak overturning resistance. They are easily tipped over or shifted due to factors such as pedestrian traffic, athlete passage, and outdoor gusts of wind, disrupting event order, causing injuries, and damaging facilities, thus resulting in low safety. Secondly, the materials used have weak protective properties and insufficient environmental adaptability. They are generally made of low-cost materials such as ordinary plastics and thin sheet metal, resulting in poor overall structural strength and impact resistance. Lacking waterproof, UV-resistant, and aging-resistant protective properties, long-term placement on outdoor track and field fields will quickly lead to fading, cracking, embrittlement, and corrosion, resulting in a short lifespan and high costs for continuous replacement and daily maintenance. Thirdly, the signage display methods are outdated and have limited information presentation effectiveness. They mainly rely on paper stickers, handwritten cards, and simple inserts to indicate lanes and athlete information. The content replacement process is cumbersome and inefficient, and the signs are prone to falling off, becoming blurred, or breaking. Furthermore, the information is only displayed on one side or in a small area, resulting in a narrow viewing angle and large blind spots, making it difficult for referees, athletes, and on-site staff to view from multiple angles. Fourth, it lacks comprehensive display capabilities for the entire event process, making it impossible to achieve visualized judgments. It can only complete basic road markings and cannot simultaneously display complete event information such as competition events, participating groups, representative teams, and athlete images. Furthermore, it lacks a graphical prompt function for starting fouls. Judgment information relies solely on referee flag signals and verbal communication, resulting in a single form of information transmission, strong subjective dependence, and a high risk of misunderstandings and disputes on the field, thus lowering the standardization and professionalism of the event. Fifth, the transportation and movement operations are cumbersome and lack adaptability to different venues. Most are fixed structures, and even the few products equipped with ordinary casters lack extension capabilities. The locking structure requires manual handling and relocation of each item during the setup of different sprint events such as the 100m and 200m, resulting in high manpower consumption and low efficiency in venue transition. The conventional casters are prone to wear and tear and can scratch the synthetic track. After placement, the positioning and anti-slip effect is poor, making it easy to slide and deviate. Furthermore, the product has limited functionality and a low level of intelligence, only able to achieve basic track division and simple marking. It fails to meet the current needs of digital and intelligent operation of events, has insufficient integration, and is difficult to match the standardized and digital management system of modern track and field events. The equipment is generally old and outdated, seriously hindering the process of intelligent transformation and upgrading of the venue. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent track and field lane pier to solve the problems of poor structural stability, outdated marking methods, limited visibility, laborious handling, single function, and inability to visualize competition rulings of traditional track and field lane piers.

[0005] To address the aforementioned problems, the present invention is implemented through the following technical solution.

[0006] An intelligent track and field lane bollard includes: a main frame, an outer shell bonded to the outside of the main frame, the main frame having a truncated pyramidal structure that is narrower at the top and wider at the bottom, and LED dot matrix displays embedded around the main frame, a sunken battery compartment centrally located at the top of the main frame, a main control module fixedly installed on one side of the inner wall of the battery compartment, a battery assembly assembled inside the battery compartment, an internal mounting hole penetrating through the middle of the inner side of the main frame, and a telescopic caster assembly installed through the internal mounting hole on the inner side of the main frame.

[0007] In one embodiment, the main frame is made of aluminum alloy, and the outer shell is made of high-strength ABS engineering plastic through one-piece injection molding. The outer shell has waterproof, UV-resistant, and anti-aging properties. The main frame and the outer shell form an inner and outer composite structure, and the outer shell is white in color to meet the usage standards of track and field event venues.

[0008] In one embodiment, the battery assembly includes a limiting strip, a compartment cover, a set of fastening screws, a battery, and a charging interface. The limiting strip is arranged circumferentially along the inner side of the battery compartment, forming a limiting installation area that matches the shape of the battery, and is used to circumferentially limit and position the battery.

[0009] In one embodiment, the battery limiting clip is engaged within the installation area enclosed by circumferentially arranged limiting strips to achieve lateral all-round limiting and fixing. The charging interface is embedded and fixed at the lower end of the side wall of the battery compartment and electrically connected to the battery. The compartment cover is closed at the upper opening of the battery compartment, and the compartment cover is locked and fixed to the limiting strips by a plurality of evenly distributed fastening screws.

[0010] In one embodiment, the telescopic caster assembly includes a snap-fit ​​plate, a hydraulic cylinder, a piston rod, a caster connecting seat plate, a sliding limiting base plate, two fastening screws, a swivel caster, a sliding limiting protrusion, and a guide limiting groove. The snap-fit ​​plate is a circular plate structure, and the radius of the snap-fit ​​plate is larger than the diameter radius of the inner assembly hole, so that the snap-fit ​​plate can be limited to overlap at the upper opening of the inner assembly hole. The bottom of the snap-fit ​​plate is fixedly connected to the non-driving end of the hydraulic cylinder. The hydraulic cylinder and the piston rod are vertically arranged throughout the internal space of the inner assembly hole.

[0011] In one embodiment, the hydraulic cylinder is vertically fixedly installed at the center of the lower end face of the snap-fit ​​plate, and a piston rod is mounted vertically downward at the drive output end of the hydraulic cylinder. The bottom end of the piston rod is fixedly connected to the caster connecting seat plate, the caster connecting seat plate is horizontally arranged, and a sliding limiting base plate is mounted on the lower end face of the caster connecting seat plate.

[0012] In one embodiment, the sliding limiting base plate is generally rectangular in shape, and several sets of fastening screws are evenly arranged in a ring at the contact surface between the sliding limiting base plate and the caster connecting seat plate. The sliding limiting base plate is locked and fixed to the caster connecting seat plate by the fastening screws, forming a detachable assembly structure. Universal casters are fixedly installed at the four corners of the bottom of the sliding limiting base plate to realize the multi-directional movement function of the equipment.

[0013] In one embodiment, multiple sets of guide and limiting grooves are vertically formed around the bottom inner sidewall of the main frame, and sliding limiting protrusions are correspondingly provided on the four outer sides of the caster connecting seat plate. The sliding limiting protrusions correspond one-to-one with the guide and limiting grooves, and the sliding limiting protrusions are slidably engaged inside the guide and limiting grooves, so that the caster connecting seat plate can slide vertically up and down along the guide and limiting grooves.

[0014] In one embodiment, the four sets of LED dot matrix displays are high-brightness display panels and realize synchronous display of information on all four sides. The main control module can control the LED dot matrix displays to intelligently switch the display content according to different working stages of the event. During the event check-in stage, the athlete's name, the event, and the participating unit information are displayed. During the preparation stage, the lane number and the athlete's name are displayed. During the athlete introduction stage, the athlete's human image is displayed. During the penalty stage, the nature of the starting foul, the disqualification, and the warning penalty information are displayed.

[0015] In one embodiment, the omnidirectional caster adopts a metal reinforced bracket combined with a silent rubber wheel structure, and is combined with a truncated pyramidal structure with a narrow top and wide bottom of the main frame and a widened base structure to lower the overall center of gravity of the equipment and increase the support area.

[0016] This invention provides an intelligent track and field lane marker. Compared with existing technologies, it has the following advantages: 1. The machine adopts a truncated pyramidal structure that is narrow at the top and wide at the bottom, combined with a widened integrated base, which lowers the center of gravity of the whole machine, increases the bottom support area, and improves the ability to resist tipping over. It can remain stable and not tip over in outdoor competition scenarios such as wind load, slight touch by personnel, and dense placement of equipment, so as to avoid affecting the progress of the competition, interfering with the referee's judgment, or causing safety hazards to the field due to the tipping of the lane pier.

[0017] 2. The internal frame is made of aluminum alloy, which is lightweight, has high structural strength, and is not easily deformed, ensuring reliable support for the main body; the outer shell is made of high-strength ABS engineering plastic, which has waterproof, UV-resistant, anti-aging, and impact-resistant properties, and can be used for a long time in outdoor sun, rain, high temperature and low temperature environments. It is not easy to fade, crack or become brittle, and the overall service life is greatly extended, reducing replacement and maintenance costs.

[0018] 3. The equipment is equipped with high-brightness LED dot matrix displays on all four sides, which output information synchronously and are visible from multiple angles, completely eliminating blind spots and improving nighttime visibility. No matter where the referees, athletes, on-site staff, or spectators are, they can clearly read the lane number, name, event, unit, human image, and penalty illustration. Information recognition is faster and more accurate, reducing communication and confirmation costs and improving the efficiency of event organization.

[0019] 4. Supports one-click switching of four core contents: check-in information, lane information, athlete images, and starting penalty diagrams. It accurately adapts to the four key stages of check-in, preparation, athlete introduction, and starting penalty. The displayed content is standardized, consistent, and updated promptly, replacing outdated methods such as handwriting, nameplates, and stickers. This improves the intelligence and standardization of the event, enhances the sense of ceremony and professionalism, and provides a visual display of starting penalties, making the results intuitive and public, reducing disputes. During the starting phase, standardized penalty diagrams can be directly displayed on the screen, simultaneously shown on all four sides for easy viewing and transparency. Compared to traditional flag signals and verbal notifications, information transmission is clearer, more consistent, and traceable, effectively reducing on-site disputes and improving the authority and smoothness of the referee's work.

[0020] 5. The bottom uses a telescopic caster assembly driven by a hydraulic cylinder and piston rod, which can be remotely controlled by one button to extend or retract the casters: When the casters are extended, the equipment can be pushed smoothly, and the silent rubber wheels will not scratch or wear the plastic track; after reaching the designated position, the casters retract, and the base directly locks to the ground; the guide limit groove and sliding limit protrusion cooperate to limit the lifting trajectory of the casters and avoid deviation and jamming; it can meet the needs of rapid transfer between different events such as 100 meters and 200 meters and different starting points, without manual handling, saving labor, efficiency and safety; the caster base plate is detachable, which makes it easy to inspect and replace the swivel casters individually.

[0021] 6. The main body of the outer shell adopts a uniform white color scheme with a simple and neat design, which blends seamlessly with the standard track and field, facilities, and competition environment, without causing glare or visual interference. It ensures clear lane markings while conforming to the visual specifications of official track and field events, enhancing the overall aesthetics and professionalism of the venue. The entire machine integrates display, intelligent control, electric mobility, and outdoor protection functions, making it easy to operate. Check-in personnel can use it after simple operation. The equipment is not limited by event, group, or gender and can be widely used in various track and field events such as sprints, hurdles, and relays. One machine can be reused for multiple events, improving the utilization rate of venue equipment and reducing the cost of event equipment configuration. Attached Figure Description

The limiting strip 601 is arranged circumferentially along the inner side of the battery compartment 4, forming a limiting installation area that matches the shape of the battery 604, and is used to circumferentially limit and position the battery 604.

[0043] The battery 604 is locked inside the installation area enclosed by the circumferentially arranged limiting strips 601, achieving lateral all-round limiting and fixing. The charging interface 605 is embedded and fixed at the lower end of the side wall of the battery compartment 4 and electrically connected to the battery 604. The compartment cover 602 covers the upper opening of the battery compartment 4, and the compartment cover 602 is locked and fixed to the limiting strips 601 by a plurality of evenly distributed fastening screws 603.

[0044] The telescopic caster assembly 8 includes a snap-fit ​​plate 801, a hydraulic cylinder 802, a piston rod 803, a caster connecting seat plate 804, a sliding limiting base plate 805, a second set of fastening screws 806, a swivel caster 807, a sliding limiting protrusion 808, and a guide limiting groove 809. The snap-fit ​​plate 801 is a circular plate structure, and the radius of the snap-fit ​​plate 801 is larger than the diameter radius of the inner mounting hole 7, so that the snap-fit ​​plate 801 can be limited and overlapped at the upper opening of the inner mounting hole 7. The bottom of the snap-fit ​​plate 801 is fixedly connected to the non-driving end of the hydraulic cylinder 802. The hydraulic cylinder 802 and the piston rod 803 are arranged vertically through the internal space of the inner mounting hole 7.

[0045] The hydraulic cylinder 802 is vertically fixedly installed at the center of the lower end face of the snap-fit ​​plate 801, and the drive output end of the hydraulic cylinder 802 is vertically downwardly mounted with a piston rod 803. The bottom end of the piston rod 803 is fixedly connected to the caster connecting seat plate 804. The caster connecting seat plate 804 is horizontally arranged, and the lower end face of the caster connecting seat plate 804 is equipped with a sliding limit base plate 805.

[0046] The sliding limit base plate 805 has a rectangular plate structure, and several sets of fastening screws 806 are evenly arranged in a ring at the contact surface between the sliding limit base plate 805 and the caster connecting seat plate 804. The sliding limit base plate 805 is locked and fixed to the caster connecting seat plate 804 by the fastening screws 806, forming a detachable assembly structure. Universal casters 807 are fixedly installed at the four corners of the bottom of the sliding limit base plate 805, realizing the multi-directional movement function of the equipment.

[0047] The bottom inner sidewall of the main frame 1 has multiple sets of guide limiting slide grooves 809 vertically arranged around it. The four outer sides of the caster connecting seat plate 804 are provided with corresponding sliding limiting protrusions 808. The sliding limiting protrusions 808 correspond one-to-one with the guide limiting slide grooves 809, and the sliding limiting protrusions 808 are slidably engaged in the inside of the guide limiting slide grooves 809, so that the caster connecting seat plate 804 can slide vertically up and down along the guide limiting slide grooves 809.

[0048] The four sets of LED dot matrix displays 3 are high-brightness display panels and can display information synchronously on all four sides. The main control module 5 can control the LED dot matrix displays 3 to intelligently switch the display content according to different working stages of the event. During the event check-in stage, the athlete's name, the event, and the information of the participating unit are displayed. During the preparation stage, the lane number and the athlete's name are displayed. During the athlete introduction stage, the athlete's human image is displayed. During the penalty stage, the nature of the starting foul, the disqualification, and the warning penalty information are displayed.

[0049] The 807 swivel caster uses a metal reinforced bracket with a silent rubber wheel structure, combined with the main frame 1's narrow-at-the-top and wide-at-the-bottom four-sided pyramidal structure and widened base structure, which lowers the overall center of gravity of the equipment and increases the support area.

[0050] During use, the basic power supply and control workflow is as follows: The battery 604 is assembled in the battery compartment 4 and is omnidirectionally limited and fixed by the limit bar 601. The compartment cover 602 seals the battery compartment 4 with fastening screws 603. The charging interface 605 can be connected to an external power source to charge the battery 604. The battery 604 provides unified power supply to the hydraulic cylinder 802 of the main control module 5, the four-sided LED dot matrix display screen 3, and the telescopic mobile caster assembly 8. The main control module 5, as the core control unit, receives remote control commands from external terminals and synchronously controls the switching of display content and the lifting and lowering of the casters.

[0051] When the secondary pier needs to be moved, the operator sends an extension command to the main control module 5 via remote control. The main control module 5 drives the hydraulic cylinder 802 to work, and the hydraulic cylinder 802 drives the piston rod 803 to extend downward. The piston rod 803 drives the caster connecting seat plate 804 to move downward in sync. The sliding limit protrusion 808 on the side wall of the sliding limit base plate 805 slides vertically downward along the guide limit slide groove 809 on the inner side of the main frame 1, which simultaneously drives the sliding limit base plate 805 and the bottom universal caster 807 to extend downward. The universal caster 807 contacts the track and lifts the whole machine. At this time, the equipment can be pushed smoothly by relying on the silent rubber universal caster 807. The rubber wheel will not scratch the plastic track surface.

[0052] After the equipment is moved to the designated position on the track, a retraction command is issued. The hydraulic cylinder 802 pulls the piston rod 803 to retract upwards, which drives the caster connecting seat plate 804, the sliding limit base plate 805, and the swivel caster 807 to retract upwards along the guide limit slide groove 809. The swivel caster 807 is completely stored inside the main frame 1, and the widened base at the bottom of the main frame 1 is completely attached to the track ground and fixed. The top-narrow and bottom-wide quadrangular pyramidal structure, combined with the widened base, lowers the center of gravity of the whole machine and increases the support area, which greatly improves the static anti-overturning ability and avoids tipping and displacement caused by gusts of wind or personnel contact.

[0053] The sliding limit base plate 805 is detachably assembled with the caster connecting seat plate 804 by fastening screw 806, which facilitates the separate inspection and replacement of the swivel caster 807 in the later stage; the snap plate 801 overlaps the upper end of the inner assembly hole 7 to realize the limit bearing of the entire telescopic mobile caster assembly 8 and ensure the stability of the lifting structure installation.

[0054] The main control module 5 receives the competition data entered by the external referee terminal and automatically switches the synchronous display content of the four LED dot matrix displays 3 in four stages to achieve 360° blind-spot-free information display: During the check-in phase: The main control module 5 controls the LED dot matrix display screen 3 to simultaneously display the competition events, groups, athlete names, and participating unit information. Referees can quickly verify the athlete's participation information from multiple angles and complete the check-in verification. Preparation and positioning phase: The main control module 5 switches the display content, and the four screens simultaneously display the lane number and the corresponding lane athlete's name, clearly dividing the track and making it easy for athletes and referees to quickly identify the corresponding positions; Athlete introduction phase: The main control module 5 retrieves the pre-stored athlete human body image data and controls the LED dot matrix display screen 3 to display the athlete human body image in full screen, enhancing the sense of ceremony and recognizability of the event; During the starting penalty phase: If an athlete false starts or commits a violation, the referee issues a penalty instruction to the main control module 5. The main control module 5 then drives the LED dot matrix display screen 3 to display a standardized penalty diagram, distinguishing the following situations: Yellow card: Warning. Two yellow cards = disqualification. Purpose: To warn against non-starting violations (improper conduct, obstruction, breach of sportsmanship, etc.); Red card: Disqualification; applicable for false starts, serious violations, or accumulating two yellow cards. Purpose: Disqualification from the competition, applicable to false starts, serious violations, and two yellow card warnings; Yellow / Black Card: First false start warning. Applicable for the first false start in an all-around event. A second false start will result in a red / black card. The top half is yellow and the bottom half is black (diagonally divided). The diagonal line runs from the top left corner to the bottom right corner, with yellow on top. Purpose: A warning sign for athletes to false start in combined events; Red and Black Card: Disqualification for false starts in combined events. This applies to a second false start. The card consists of a red upper half and a black lower half (diagonally divided) from the top left to the bottom right corner, with red on top. Purpose: A penalty mark for an athlete's second false start in an all-around event; Green Card: No false start, restart, applicable to non-subjective start interruptions such as starting gun malfunction or external interference. Purpose: To determine if a stoppage at the start is not the athlete's fault and to arrange a restart; Red and white card: Represents protests against the competition and reserves the right to appeal. The card is divided diagonally from the top left to the bottom right, with red on top. Purpose: In combined events, athletes may protest during the competition and retain the right to appeal.

[0055] The judgment results are displayed simultaneously on all four sides, which directly conveys the judgment information, eliminates misunderstandings caused by verbal or flag signals, and reduces disputes on the field.

[0056] The main frame 1, made of aluminum alloy, serves as the internal load-bearing skeleton. It is lightweight, has high structural strength, and is not easily deformed. The outer shell 2 is a one-piece injection-molded high-strength ABS shell. The shell is waterproof, UV resistant, anti-aging, and impact resistant. It can withstand sun exposure, rain, and high and low temperature environments when used outdoors. It will not fade, crack, or become brittle over long-term use. The outer shell 2 is uniformly white, which matches the standard red plastic track, minimizes visual interference, and meets the visual specifications of official track and field events.
