Description

Technical Field

[0001] This utility model relates to an alarm device, specifically a dual warning system for correctly wearing an electric bicycle safety helmet. Background Technology

[0002] According to statistics from the Ministry of Public Security, over 80% of deaths in motorcycle and electric bicycle road traffic accidents are caused by traumatic brain injury. Studies have shown that correctly wearing a helmet can reduce the risk of death in traffic accidents by 60% to 70%. However, the phenomenon of not wearing helmets correctly while riding motorcycles and electric bicycles remains widespread. A significant reason for this is that current electric bicycle helmets do not have the function of compelling riders to wear them correctly. Chinese utility model patent CN214072007U discloses an "electric bicycle helmet wearing warning system." This system works by having the rider sit on the electric bicycle seat and apply pressure to the seat, which closes a switch underneath the seat. This activates a buzzer circuit inside the electric bicycle, triggering an alarm to remind the rider to wear a helmet. Once the rider puts on the helmet and connects the helmet strap, the wireless transmitter in the helmet is energized and transmits a signal to a wireless receiver module in the seat. Upon receiving the signal, the wireless receiver module disconnects the buzzer circuit, de-energizing the buzzer and stopping the alarm. The problem with this solution is that if the rider simply connects the safety harness without wearing a helmet, the buzzer will stop ringing. This does not effectively force riders to wear safety helmets correctly, which should include both putting on the helmet properly and fastening the harness. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies that fail to effectively enforce proper helmet use by riders, this invention provides a dual-warning system for correctly wearing electric bicycle helmets. The system integrates a remote key with the helmet, requiring the rider to connect the helmet strap and fasten the buckle before energizing the remote key. By applying sensor and remote control technologies to the helmet, the starting and operation of the electric bicycle are remotely linked to the helmet. Simultaneously, the system detects when the rider is not wearing a helmet and sends an alarm. Furthermore, by incorporating sensor and seatbelt technology, the system detects when the helmet is not properly fastened and sends an alarm, thus effectively enforcing proper helmet use.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a dual warning system for the correct wearing of an electric bicycle safety helmet, including a 2.4G wireless remote control module, a wireless single-channel remote control switch, an unwearing induction switch, a wearing induction switch, a buckle switch, a remote control key module, an unfastening induction switch, and a reel. The 2.4G wireless remote control module is installed inside the electric bicycle and connected in series with the electric bicycle's battery and power switch to form a first circuit. When the driver starts and drives the electric bicycle, the electric bicycle's power switch is closed, the first circuit is energized, and the 2.4G wireless remote control module is powered. After being powered, the 2.4G wireless remote control module and the wireless single-channel remote control switch built into the safety helmet are interconnected through frequency pairing. The energized 2.4G wireless remote control module continuously transmits command signals to the wireless single-channel remote control switch. After detecting the continuous command signals, the wireless single-channel remote control switch changes from normally open to normally closed. When the electric bicycle is turned off, the power switch is turned off, the 2.4G wireless remote control module loses power and stops transmitting command signals, and the wireless single-channel remote control switch returns to normally open after detecting the interruption of the command signal.

[0005] The aforementioned electric bicycle safety helmet features a dual-warning system for correct wearing. The wireless single-channel remote control switch is electrically connected to the first buzzer, the unfastening sensor switch, and the power supply, forming a second circuit. The unfastening sensor switch consists of a helmet shell, a spring, a push rod, a pad, a rocker arm, a first unipolar Hall element OH44E, and a first magnet. When the rider closes the power switch to start and run the electric bicycle, the 2.4G wireless remote control module is energized and controls the wireless single-channel remote control switch to be normally closed. Simultaneously, when the rider is not wearing a helmet, the spring, connected at one end to the inner top of the helmet shell, is in a naturally extended state. The push rod connected to the other end of the spring fixes one end of the rocker arm, causing the first magnet, built into the other end of the rocker arm, to be directly opposite the first unipolar Hall element OH44E in the unfastening sensor switch. When the helmet release sensor is normally closed, the second circuit is energized, and the first buzzer sounds an alarm. When the driver closes the power switch to start and run the electric bicycle, the 2.4G wireless remote control module is energized and controls the wireless single-channel remote control switch to be normally closed. At the same time, when the driver is wearing a safety helmet, their head presses against the push rod, pushing the rocker arm to move. The first magnet built into the rocker arm moves away from the first unipolar Hall element OH44E in the helmet release sensor, causing the helmet release sensor to change from normally closed to normally open. The second circuit is disconnected, and the first buzzer does not sound an alarm. When the electric bicycle is turned off, the 2.4G wireless remote control module loses power and stops transmitting command signals. The wireless single-channel remote control switch detects the interruption of the command signal and returns to normally open. The second circuit is disconnected, and the first buzzer does not sound an alarm whether the driver is wearing a safety helmet or not.

[0006] The aforementioned electric bicycle safety helmet features a dual-warning system for correct wearing. The second buzzer, along with the buckle release sensor, wearing sensor, and power supply, forms a third circuit. The wearing sensor consists of the helmet shell, spring, push rod, padding, rocker arm, a second unipolar Hall element OH44E, and a first magnet. The buckle release sensor consists of a reel, first strap, buckle, second magnet, third unipolar Hall element OH44E, and second strap. The third circuit's operation is independent of the electric bicycle's start-up or running state. When the rider wears the helmet, their head presses against the push rod, pushing the rocker arm. This causes the first magnet, embedded in the rocker arm, to move with the rocker arm. When the push rod is limited by the helmet padding, the first magnet is directly facing the second unipolar Hall element OH44E in the wearing sensor, causing the wearing sensor to change from normally open to normally closed. Simultaneously, when the rider's buckle is not engaged, the reel retracts the first strap, pulling the second magnet, embedded in the buckle pin handle, closer to the buckle release sensor. The third monopole Hall element OH44E in the system keeps the release sensor switch normally closed, energizing the third circuit and triggering the second buzzer. When the driver is wearing a helmet, the first magnet is positioned close to the second monopole Hall element OH44E, keeping the wearing sensor switch normally closed. Simultaneously, when the driver fastens the helmet, the fastening pin is inserted into the fastening socket. The limited length of the second strap connecting the fastening socket causes the second magnet in the fastening pin handle to separate from the third monopole Hall element OH44E in the release sensor switch, changing the release sensor switch from normally closed to normally open, disconnecting the third circuit, and preventing the second buzzer from sounding. When the driver is not wearing a helmet, a spring connected to the inside of the top of the helmet shell returns to its natural extension state, pushing a push rod connected to the other end of the spring to move a rocker arm. This causes the first magnet built into the rocker arm to move away from the second monopole Hall element OH44E in the wearing sensor switch, returning the wearing sensor switch to its normally open state, disconnecting the third circuit, and preventing the second buzzer from sounding whether the helmet is fastened or not.

[0007] The above-mentioned electric bicycle safety helmet has a dual warning system when worn correctly. The remote key module is connected in series with the buckle switch and the power supply to form a fourth circuit. The buckle switch consists of a buckle pin and a buckle socket. The buckle pin is connected to the buckle pin handle, the buckle pin handle is connected to the first strap, the first strap is connected to the reel, and the buckle socket is connected to the second strap. When the driver inserts the buckle pin into the buckle socket, the buckle switch changes from normally open to normally closed, the fourth circuit is energized, and the remote key module is powered and can be used.

[0008] The aforementioned electric bicycle safety helmet features a dual warning system for correct wearing. The power supply, remote key module, wireless single-channel remote control switch, first buzzer, second buzzer, unfastening sensor switch, wearing sensor switch, and reel are all located within the helmet. The unfastening sensor switch is located within the helmet and its buckle. The buckle switch is located within the buckle. The remote key module button is located on the outside of the helmet. The pairing button for the wireless single-channel remote control switch within the helmet is located on the inside of the helmet. The pairing button for the 2.4G wireless remote control module in the electric bicycle is located externally on the electric bicycle's dashboard.

[0009] The above-mentioned electric bicycle safety helmet with a correct wearing dual warning system is as follows: the 2.4G wireless remote control module, the electric bicycle battery, and the electric bicycle power switch are connected by wires; the wireless single-channel remote control switch, the first buzzer, the first unipolar Hall element OH44E, and the power supply are connected by wires; the second buzzer, the second unipolar Hall element OH44E, the third unipolar Hall element OH44E, and the power supply are connected by wires; the remote control key module, the buckle socket, and the power supply are connected by wires; the wires are built into the safety helmet and its straps.

[0010] The beneficial effects of this utility model are as follows: By combining the remote control key with the safety helmet, the remote control key module circuit can only be connected and the remote control key function can only be used after the driver has fastened the safety helmet. The wireless single-channel remote control switch, the first buzzer, the unfastening sensor switch, and the power supply are electrically connected. When the electric bicycle starts and runs, the 2.4G wireless remote control module controls the wireless single-channel remote control switch to close. Simultaneously, if the driver is not wearing a safety helmet, the unfastening sensor switch will close, and both the wireless single-channel remote control switch and the unfastening sensor switch will close, energizing the first buzzer. The second buzzer, the unfastening sensor switch, the wearing sensor switch, and the power supply are electrically connected. When the driver is wearing a safety helmet, the wearing sensor switch will close. Simultaneously, if the driver has not fastened the helmet, the unfastening sensor switch will close, and both the wearing sensor switch and the unfastening sensor switch will close, energizing the second buzzer. This effectively compels the driver to wear a safety helmet and fasten it properly when riding an electric bicycle. Attached Figure Description

[0020] like Figures 1-7 As shown, this utility model discloses a dual-warning system for correctly wearing an electric bicycle safety helmet, comprising a 2.4G wireless remote control module 2, a single-channel wireless remote control switch 3, an unfastening induction switch 5, a wearing induction switch 6, a buckle switch 7, a remote control key module 8, an unfastening induction switch 9, and a reel 22. The 2.4G wireless remote control module 2 is installed inside the electric bicycle and connected in series with the electric bicycle's battery and power switch 1 to form a first circuit. When the driver starts and drives the electric bicycle, the power switch 1 is closed, and the first circuit is energized. When the 2.4G wireless remote control module 2 is powered on, it connects with the wireless single-channel remote control switch 3 built into the safety helmet via frequency pairing. The powered 2.4G wireless remote control module 2 continuously transmits command signals to the wireless single-channel remote control switch 3. After detecting the continuous command signals, the wireless single-channel remote control switch 3 changes from normally open to normally closed. When the electric bicycle is turned off, the power switch 1 is off, the 2.4G wireless remote control module 2 loses power and stops transmitting command signals, and the wireless single-channel remote control switch 3 returns to normally open after detecting the interruption of the command signal.

[0021] In this example, the wireless single-channel remote control switch 3 is electrically connected to the first buzzer 4, the dismounting sensor switch 5, and the power supply to form a second circuit. When the wireless single-channel remote control switch 3 is normally closed, and the driver is not wearing a safety helmet, the spring 18 connected to the inner top of the safety helmet shell 17 is in a naturally extended state. The push rod 19 connected to the other end of the spring 18 fixes one end of the rocker arm 20, so that the first magnet 11 built into the other end of the rocker arm 20 is aligned with the first unipolar Hall element OH44E10 near the dismounting sensor switch 5, making the dismounting sensor switch 5 normally closed, the second circuit is energized, and the first buzzer 4 sounds an alarm; when the wireless single-channel remote control switch 3 is normally closed... Simultaneously, when the driver wears a safety helmet, their head presses against the push rod 19, pushing the rocker arm 20 to move. This causes the first magnet 11, built into the rocker arm 20, to move away from the first single-pole Hall element OH44E10 in the dismounting sensor switch 5, causing the dismounting sensor switch 5 to change from normally closed to normally open. The second circuit is disconnected, and the first buzzer 4 does not sound an alarm. When the driver disconnects the power switch 1, turning off the electric bicycle, the 2.4G wireless remote control module 2 loses power and stops transmitting command signals. The wireless single-channel remote control switch 3 detects the interruption of the command signal and returns to normally open, disconnecting the second circuit. Whether the driver wears a safety helmet or not, the first buzzer 4 will not sound an alarm.

[0022] In this example, the second buzzer 15 is electrically connected to the wearing induction switch 6, the unfastening induction switch 9, and the power supply, forming a third circuit. The wearing induction switch 6 consists of a safety helmet shell 17, a spring 18, a push rod 19, a pad 16, a rocker arm 20, a second unipolar Hall element OH44E12, and a first magnet 11. The unfastening induction switch 9 consists of a reel 22, a first strap 23, a buckle 26, a second magnet 13, a third unipolar Hall element OH44E14, and a second strap 28. The on / off state of the third circuit is independent of the starting or running state of the electric bicycle. When the driver puts on the safety helmet, their head presses against the push rod 19, pushing the rocker arm 20. This causes the first magnet 11, built into the rocker arm 20, to move with the rocker arm 20. When the push rod 19 is limited by the safety helmet pad 16, the first magnet 11 is directly aligned with the second monopole Hall element OH44E12 in the wearing induction switch 6, causing the wearing induction switch 6 to change from normally open to normally closed. At the same time, when the driver's buckle 26 is not inserted, the reel 22 retracts the first strap 23 and pulls the second magnet 13, built into the buckle pin handle 24, closer to the third monopole Hall element in the unfastening induction switch 9. Component OH44E14 keeps the release sensor switch 9 normally closed, energizing the third circuit and triggering the second buzzer 15. When the driver is wearing a safety helmet, the first magnet 11 is directly opposite the second monopole Hall element OH44E12, keeping the wearing sensor switch 6 normally closed. Simultaneously, when the driver inserts the buckle 26, the buckle pin 25 is inserted into the buckle socket 27. The second strap 28 connecting the buckle socket 27 has a limited length, causing the second magnet 13 in the buckle pin handle 24 to separate from the third monopole Hall element OH44E14 in the release sensor switch 9, thus triggering the release sensor. When switch 9 changes from normally closed to normally open, the third circuit is disconnected, and the second buzzer 15 does not sound an alarm. When the driver is not wearing a safety helmet, the spring 18, which is connected to the inside of the top of the safety helmet shell 17, returns to its natural extended state, pushing the push rod 19 connected to the other end of the spring 18 to move the rocker arm 20. This causes the first magnet 11 built into the rocker arm 20 to move away from the second unipolar Hall element OH44E12 in the wearing induction switch 6, so that the wearing induction switch 6 returns to its normally open state, the third circuit is disconnected, and the second buzzer 15 does not sound an alarm whether the buckle 26 is inserted or not.

[0023] In this example, the remote key module 8 is connected in series with the latch switch 7 and the power supply to form the fourth circuit. The latch switch 7 consists of a latch pin 25 and a latch socket 27. The latch pin 25 is connected to the latch pin handle 24, the latch pin handle 24 is connected to the first lacing strap 23, the first lacing strap 23 is connected to the reel 22, and the latch socket 27 is connected to the second lacing strap 28. When the driver inserts the latch pin 25 into the latch socket 27, the latch switch 7 changes from normally open to normally closed, the fourth circuit is energized, and the remote key module 8 is powered and can be used.

[0024] In this example, the power supply, remote key module 8, wireless single-channel remote control switch 3, first buzzer 4, second buzzer 15, unfastening sensor switch 5, wearing sensor switch 6, and reel 22 are installed in the safety helmet; the unfastening sensor switch 9 is installed in the safety helmet and its buckle 26; the third unipolar Hall element OH44E14 is built into the safety helmet and located next to the exit of the first strap 23; the buckle switch 7 is installed in the buckle 26; the remote key module button 21 is located on the outside of the safety helmet; the frequency pairing button of the wireless single-channel remote control switch 3 in the safety helmet is located on the inside of the safety helmet; the frequency pairing button of the 2.4G wireless remote control module 2 in the electric bicycle is located on the outside of the electric bicycle dial.

[0025] In this example, the 2.4G wireless remote control module 2, the electric bicycle battery, and the electric bicycle power switch 1 are connected by wires; the wireless single-channel remote control switch 3, the first buzzer 4, the first unipolar Hall element OH44E10, and the power supply are connected by wires; the second buzzer 15, the second unipolar Hall element OH44E12, the third unipolar Hall element OH44E14, and the power supply are connected by wires; the remote control key module 8, the buckle socket 27, and the power supply are connected by wires; the wires are built into the safety helmet and its straps.

[0026] When this invention is in operation, if the electric bicycle is stopped and the driver is not wearing a helmet and has not fastened the buckle 26, the remote control key module 8, the first buzzer 4, and the second buzzer 15 are all de-energized. If the electric bicycle is stopped and the driver is wearing a helmet but has not fastened the buckle 26, the remote control key module 8 and the first buzzer 4 are both de-energized, while the second buzzer 15 is energized and alarms. If the electric bicycle is stopped and the driver is wearing a helmet and has fastened the buckle 26, the remote control key module 8 is energized and usable, while the first buzzer 4 and the second buzzer 15 are both de-energized. If the electric bicycle is stopped and the driver is not wearing a helmet but has fastened the buckle 26, the remote control key module 8 is energized and usable, while the first buzzer 4 and the second buzzer 15 are both de-energized. When the electric bicycle is in operation and the driver is wearing a safety helmet and has fastened the buckle 26, the remote key module 8 is powered on and usable, while the first buzzer 4 and the second buzzer 15 are de-energized; when the electric bicycle is in operation and the driver is wearing a safety helmet but has not fastened the buckle 26, both the remote key module 8 and the first buzzer 4 are de-energized, and the second buzzer 15 is energized to sound an alarm; when the electric bicycle is in operation and the driver is not wearing a safety helmet and has not fastened the buckle 26, both the remote key module 8 and the second buzzer 15 are de-energized, and the first buzzer 4 is energized to sound an alarm; when the electric bicycle is in operation and the driver is not wearing a safety helmet but has fastened the buckle 26, the remote key module 8 is powered on and usable, the first buzzer 4 is energized to sound an alarm, and the second buzzer 15 is de-energized. The remote key module 8 can only function when a safety helmet is worn and the buckle 26 is properly fastened; regardless of whether the electric bicycle is running or not, an alarm will sound as long as the safety helmet is worn and the buckle 26 is not fastened; as long as the electric bicycle is running, the alarm will not sound only when the safety helmet is worn and the buckle 26 is properly fastened, thus achieving the purpose of forcing the driver to wear a safety helmet correctly.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. In addition to electric bicycles, this utility model can also be applied to motorcycles. The sensing and remote control technology path adopted in this utility model can be replaced by other equivalent or similar alternative paths in the same professional field. Any changes or substitutions conceived without creative labor should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope defined in the claims.
