Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, and in particular to a wireless synchronous electronic lap counter and buzzer reminder system with multi-mode start adaptation. Background Technology

[0002] Track and field competitions are comprehensive sports events based on walking, running, jumping, and throwing. They are divided into two main categories: field events and track events. Track events specifically refer to speed events held on a track or designated road, with the winner determined by the time taken. The core of the competition lies in the contest of speed and endurance. From sprints and middle-distance running to hurdles and relays, track events have always been the most entertaining and competitive part of track and field, showcasing humanity's eternal pursuit of "faster".

[0003] Modern track and field events use electronic starting systems, the core of which is to ensure that all athletes receive the starting signal simultaneously. After the starter triggers the electronic starting device, the system will broadcast the standard starting sound through an audio system and simultaneously trigger flashlights installed near the starting line to provide a clear visual signal. This "sound and light synchronization" system replaces the traditional gunpowder starting gun, fundamentally guaranteeing the immediacy, consistency and fairness of the starting signal.

[0004] Existing electronic starting systems typically only provide starting prompts. In races such as long-distance running, additional lap counting equipment is required. This means that after each race, staff need to repeatedly set up the lap counting equipment. Multiple devices work together, but they are relatively independent and only coordinate through wires or wireless transmission, making setup cumbersome and inconvenient to use.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0032] Reference Figure 1 and Figure 2 As shown, this is the first embodiment of the present invention. This embodiment provides a wireless synchronous electronic loop counting and buzzer reminder system with multi-mode command adaptation, including: Rack 1, with a fixed box 4 installed inside. Display component 2 is located on the top of the rack 1. Display component 2 includes a fixed base 204 fixedly installed on the top of the rack 1. A fixed housing 201 is fixedly installed on the top of the fixed base 204. A timing module 202 is fixedly installed on the outer surface of the fixed housing 201. A ring counting module 205 is located on the outer surface of the fixed housing 201 below the timing module 202. The fixed base 204 is equipped with a remote control, which can be used to conveniently control the lap counting module 205 to increase or decrease the number of laps and the timing module 202 to start or stop.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, two fixed lights 203 are installed on the outer surface of the fixed chassis 201; The two fixed lights 203 are red and green, respectively, to indicate the waiting process and the process in progress.

The speaker 6 has a wireless connection module and a battery inside. The speaker 6 can be wirelessly connected to the starting pistol 502 through the wireless connection module. The speaker 6 can be detached and used when needed. The connection relationship, working principle and operation sequence between the wireless connection module, the battery and other components are existing technologies and will not be described in detail here. Mounting plates are installed on both sides of the speaker 6. The outer surface of the fixed box 4 is provided with slots that mate with the speaker 6. Threaded pins are provided on both sides of the slots on the outer surface of the fixed box 4. The inside of the mounting plate is provided with through holes that mate with the threaded pins. The threaded pins pass through the through holes and are threadedly connected to locking caps. The locking caps and threaded pins work together to lock and limit the speaker 6 inside the fixed box 4. The starting sound is emitted by the sound system 6 and the loudspeaker 206 to signal the start of the competition. The speaker 6 is equipped with a signal receiver on its exterior. The signal receiver connects the starting pistol 502 and the speaker 6, so that after the starting pistol 502 pulls the trigger, the signal receiver receives the command and sends the command to the speaker 6, thereby playing the specified command sound effect through the speaker 6.

[0035] Furthermore, at the same time as the starting command is issued, the timing module 202 starts timing. In the long-distance race, the current number of race laps can also be displayed by controlling the lap counting module 205. On the last lap, a buzzer sound is emitted through the speaker 206 and the sound system 6. Example

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment and includes a prompting component 3. The prompting component 3 is disposed on both sides of the fixed housing 201. The prompting component 3 includes a fixing block 314 fixedly installed on the bottom of both sides of the fixed housing 201. A rotating box 301 is provided on both sides of the fixed housing 201. A light prompting module is provided on the outer surface of the rotating box 301. A connecting block 306 is fixedly connected to the bottom of the rotating box 301. A rotating gear 308 is fixedly connected to the outer surface of the connecting block 306. A spline shaft 313 is movably connected inside the fixing block 314 through a rotating shaft. An L-shaped moving plate 307 is movably connected inside the fixing block 314. A plug rod 310 is fixedly connected inside the vertical part of the L-shaped moving plate 307. A locking tooth block 309 is fixedly connected to the end of the plug rod 310 near the rotating gear 308.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, top plates 315 are fixedly installed on both sides of the top of the fixed housing 201, a connecting rod 304 is fixedly connected to the top of the rotating box 301, a fixed plate 316 is fixedly connected to the top of the connecting rod 304, a pressing plate 302 is fixedly connected to the outer surface of the connecting rod 304, and a pressing spring 303 is fixedly connected between the pressing plate 302 and the fixed plate 316. The lower surface of the extrusion plate 302 is provided with several protrusions, and the top of the rotating box 301 is fixed by the extrusion of the extrusion plate 302 and the top plate 315. The outer surface of the top plate 315 has an opening that mates with the connecting rod 304. The connecting rod 304 can be inserted into the opening and then pressed against the upper surface of the top plate 315 by the pressing plate 302, thereby achieving fixation.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the outer surface of the connecting block 306 is fixedly connected to the insert plate 305, the outer surface of the fixing block 314 is provided with a slot that cooperates with the insert rod 310 and the connecting block 306, and both sides of the inner wall of the slot on the outer surface of the fixing block 314 are provided with grooves that cooperate with the rotating gear 308, and the inner wall of the groove is provided with a rectangular opening that cooperates with the locking tooth block 309.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the horizontal part of the L-shaped moving plate 307 is provided with teeth on the side near the spline shaft 313, and the L-shaped moving plate 307 is connected to the spline shaft 313 by meshing through the teeth. A T-shaped limiting block is provided on the horizontal part of the L-shaped moving plate 307 away from the spline shaft 313, and a limiting groove that cooperates with the T-shaped limiting block is provided on the inner wall of the inner cavity of the fixing block 314.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, a moving rod 312 is fixedly connected to the side of the L-shaped moving plate 307 away from the rotating gear 308, and the end of the moving rod 312 away from the L-shaped moving plate 307 passes through the outer surface of the fixing block 314.

[0041] like Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, a compression spring 311 is fixedly connected between the vertical part of the L-shaped moving plate 307 away from the rotating gear 308 and the inner wall of the fixed block 314. The inner wall of the fixed block 314 is provided with an insertion hole that cooperates with the insertion rod 310. The end of the insertion rod 310 away from the rotating gear 308 passes through the vertical part of the L-shaped moving plate 307 and the inside of the compression spring 311 and is inserted into the insertion hole.

[0042] Furthermore, by pulling the moving rod 312, the L-shaped moving plate 307 is moved, which in turn moves another L-shaped moving plate 307 via the spline shaft 313. The L-shaped moving plate 307 moves the locking gear block 309 via the insert rod 310, thereby unlocking the rotating gear 308 and allowing the rotating box 301 to rotate. This allows the angle of the indicator light 508 to be adjusted, preventing the indicator light 508 from affecting the athletes' competition while ensuring that the athletes and key timing personnel can observe the indicator light 508 normally. Example

[0043] Reference Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 This is the second embodiment of the present invention, which is based on the previous embodiment. The command component 5 is disposed on the outer surface of the fixed box 4. The command component 5 includes two mounting blocks 504 fixedly connected to the outer surface of the fixed box 4. A rotating block 505 is disposed between the two mounting blocks 504. Movable rods 506 are fixedly connected to both ends of the rotating block 505. The rotating block 505 is hinged to the mounting blocks 504 through the movable rods 506. A rotating box 503 is fixedly connected to the top of the rotating block 505. A command gun 502 is disposed inside the rotating box 503. An indicator light 508 is installed on the front of the command gun 502. The starting pistol 502 has a signal transmitting module on its top, and the fixed housing 201 has a signal receiving module on its top. After the signal transmitting module emits a signal by firing the trigger 515, the fixed housing 201 receives the signal through the signal receiving module, thereby controlling the timing module 202 to start operating. The starting pistol 502 also has a wireless connection module inside, enabling it to wirelessly connect to the speaker 6, thus allowing control of the speaker 6 via the starting pistol 502. Furthermore, the starting pistol 502 also includes a wireless connection module for wireless connectivity.

[0044] like Figure 8 , Figure 9 and Figure 10As shown, in this embodiment, a fixed cover plate 501 is fixedly connected to the outer surface of the fixed box 4. A torsion spring 507 is provided between the rotating block 505 and the mounting block 504. Limiting grooves that cooperate with the torsion spring 507 are provided at both ends of the rotating block 505 and on the side of the mounting block 504 near the rotating block 505. The two ends of the torsion spring 507 are respectively inserted into the limiting grooves.

[0045] like Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment, a push switch 511 is provided at the tail of the starting pistol 502, a battery compartment 510 is provided on the side of the starting pistol 502, a firing trigger 515 is installed on the outer surface of the starting pistol 502, an arc-shaped rotating plate 509 is hinged to the outer surface of the starting pistol 502, an abutment block 512 is fixedly connected to the inner side of the arc-shaped rotating plate 509, a locking plate 513 is fixedly connected to the bottom of the arc-shaped rotating plate 509, two rotating rods 514 are hinged to the outer surface of the starting pistol 502, a limit protrusion is provided on the outer surface of the rotating rod 514, and a limit groove that cooperates with the limit protrusion is provided on the outer surface of the locking plate 513. Both the bottom of the starting pistol 502 and the outer surface of the fixed housing 201 are equipped with sockets, which facilitate the connection of wires. This allows the starting pistol 502 and the fixed housing 201 to be connected by wires (or wirelessly), making it convenient for users to choose which method to use for control and ensuring normal operation in environments with multiple signal sources of interference.

[0046] Furthermore, firstly, pressing the push switch 511 confirms readiness to fire. Then, rotating the two rotating levers 514 opens them, causing the levers 514 to separate from the locking plate 513. This allows the arc-shaped rotating plate 509 to rotate open, which in turn causes the abutment block 512 to rotate open, thus exposing the firing trigger 515. These two steps prevent accidental activation of the firing trigger 515 from affecting the game's progress. The connection relationships, working principles, and operating sequences between the signal transmitting module, signal receiving module, sound 6, speaker 206, and other components are existing technologies and will not be elaborated upon here.

[0047] Working principle: During track and field events, the angle of the rotating box 301 is adjusted according to the starting position. Pulling the moving rod 312 moves the L-shaped moving plate 307, which in turn moves another L-shaped moving plate 307 via the splined shaft 313. The L-shaped moving plate 307 then moves the locking gear block 309 via the insert rod 310, unlocking the rotating gear 308 and allowing the rotating box 301 to rotate. This adjusts the angle of the indicator light 508, preventing it from interfering with the athletes' performance while ensuring the safety of the athletes and key timers. Personnel can observe the indicator light 508 normally. Then, they can rotate the rotating box 503 outwards, revealing the starting pistol 502 inside. The starting pistol 502 can then be removed. After releasing the rotating box 503, the torsion spring 507, the rotating block 505, and the limiting groove on the outer surface of the mounting block 504 will rotate the rotating box 503 back to its original position. The interaction between the rotating box 503 and the fixed cover plate 501 provides protection for the starting pistol 502 when not in use. Before using the starting pistol 502, it needs to be unlocked through two steps. To prevent accidental activation, the first step is to press the push switch 511 to confirm readiness to fire. The second step involves rotating the two rotating levers 514, separating them from the locking plate 513. This allows the arc-shaped rotating plate 509 to rotate and open, which in turn opens the abutment block 512, exposing the firing trigger 515. These two steps prevent accidental activation of the trigger 515 from affecting the game's progress. At the start of the game, the trigger is pressed, and the firing signal is transmitted between the signal transmitting module and the signal receiving module on top of the fixed housing 201. The system controls the speaker 206 and the sounder 6 to issue the starting command. At the same time, it controls the fixed light 203 on the outer surface of the rotating box 301 to illuminate, assisting the athlete in starting the race and prompting the manual timer to start timing. The starting command also activates the timing module 202 to start timing. In long-distance races, the lap counter module 205 can be controlled to display the current number of laps. On the last lap, the speaker 206 and the sounder 6 will emit a buzzer sound to remind the athlete, thus completing the use of the starting buzzer system in track and field events.
