Technical Field
[0001] The utility model relates to an intelligent reminder device for wearing a helmet, in particular to an intelligent helmet and a vehicle-mounted device. Background Art
[0002] One helmet and one belt, always safe. Traffic safety is related to the happiness of every family, and even more to the harmony and stability of the entire society. A safe, civilized and orderly traffic environment requires the joint efforts of all people. Vehicles (such as electric vehicles) are popular among the public because of their convenience and speed, and are widely used in various short-distance transportation scenarios. However, some riders have a weak awareness of traffic safety and do not wear helmets properly, which affects their own travel safety. Utility Model Content
[0003] The utility model aims to provide an intelligent helmet and a vehicle-mounted device, which are convenient for reminding riders to wear helmets.
[0004] The technical solution provided by the utility model is:
[0005] The utility model provides a smart helmet and a vehicle-mounted device, comprising a smart helmet and a vehicle-mounted device;
[0006] The smart helmet comprises a helmet body, a first human body sensing module, a helmet strap pin detection module, a wireless communication transmission module and a first control module;
[0007] The first human body sensing module, the helmet strap pin detection module, the wireless communication transmission module and the first control module are all arranged on the helmet body;
[0008] The first human body sensing module, the helmet strap latch detection module and the wireless communication transmission module are all electrically connected to the first control module;
[0009] The wireless communication transmitting module is used for wireless communication with the wireless communication receiving module in the vehicle-mounted device.
[0010] The first human body sensing module and the helmet strap latch detection module are used to detect whether the rider wears the helmet properly (whether the helmet is worn and the helmet strap latch is inserted in place), and output a detection signal to the first control module, and the first control module sends a corresponding signal to the vehicle-mounted device through the wireless communication transmission module. If it is detected that the rider has worn the helmet, the first control module sends a signal indicating that the helmet is worn to the vehicle-mounted device through the wireless communication transmission module.
[0011] In a possible implementation, the first human body sensing module includes an infrared grating; the infrared grating includes a group of a transmitter and a receiver for transmitting and receiving infrared light beams, and the transmitter and the receiver are respectively installed on two inner sides of the helmet.
[0012] The transmitter emits an infrared beam, and the receiver receives the beam. When the rider wears a helmet, the beam will be blocked, thereby detecting whether the rider is wearing a helmet.
[0013] In a possible implementation, the helmet strap latch detection module includes a travel switch installed in the helmet strap latch.
[0014] In a possible implementation, the output end of the first human body sensing module and the output end of the helmet strap pin detection module are electrically connected to the first control module via a logic AND circuit.
[0015] In a possible implementation, the first control module includes a first normally open contact and a second normally open contact;
[0016] The first normally open contact is electrically connected to the output end of the first human body sensing module to form a human body sensing circuit; the second normally open contact is electrically connected to the output end of the helmet strap pin detection module to form a helmet strap pin detection circuit;
[0017] The first normally open contact and the second normally open contact are connected in series in the working loop of the wireless communication transmitting module.
[0018] The human body induction loop and the helmet strap latch detection loop are connected in series to form an AND logic loop. When the rider wears the helmet, the human body induction loop is closed. When the helmet strap latch is inserted into place, the helmet strap latch detection loop is closed. When the human body induction loop is closed and the helmet strap latch detection loop is closed, the working loop of the wireless communication transmission module is closed, and the wireless communication transmission module sends a signal indicating that "the helmet is worn" to the vehicle-mounted device; otherwise, the wireless communication transmission module may send a signal indicating that "the helmet is not worn" to the vehicle-mounted device, or may not send a signal.
[0019] In a possible implementation, the smart helmet also includes a first signal indication circuit; the first signal indication circuit includes a first indicator light electrically connected to the first control module, which is used to indicate whether the rider is wearing the helmet properly (a blue indicator light can be used).
[0020] In a possible implementation, the smart helmet further includes a power module mounted on the helmet body, and the power module is used to supply power to the power-consuming modules mounted on the helmet body. For example, the power supply can supply power to the first human body sensing module, the helmet strap pin detection module, the wireless communication transmission module, and the first control module.
[0021] In a possible implementation, the power module includes a rechargeable battery.
[0022] In a possible implementation, the power module further includes a solar charging battery panel connected to the rechargeable battery.
[0023] Therefore, the smart helmet can be powered by a safe, reliable and portable rechargeable battery plus a solar charging panel.
[0024] In a possible implementation, the power module further includes a wireless charging receiving module connected to the rechargeable battery, and the wireless charging receiving module is used to couple with the wireless charging transmitting module in the vehicle-mounted device for wireless charging when the helmet is placed in a specific part of the vehicle.
[0025] In a possible implementation manner, the wireless charging receiving module includes a charging protection circuit.
[0026] The vehicle-mounted device includes a second human body sensing module, a voice prompting module, a wireless communication receiving module and a second control module;
[0027] The second human body sensing module, the voice prompt module, the wireless communication receiving module and the second control module are all arranged on the vehicle;
[0028] The second human body sensing module, the voice prompt module and the wireless communication receiving module are all electrically connected to the second control module;
[0029] The second human body sensing module is used to detect whether there is a person riding the vehicle, and output a detection signal to the second control module, and the second control module outputs a corresponding signal to the voice prompt module;
[0030] When the second control module detects that a person is riding the vehicle through the second human body sensing module, the second control module controls the voice prompt module to automatically play a voice prompt, such as outputting a voice prompt "Please wear a helmet";
[0031] The wireless communication receiving module is used to perform wireless communication with the wireless communication transmitting module on the smart helmet and receive signals sent by the wireless communication transmitting module;
[0032] The wireless communication receiving module is electrically connected to the second control module. The second control module determines whether the rider has worn a helmet based on the signal received by the wireless communication receiving module. If it is determined that the rider has worn a helmet, it can output a signal to control the voice prompt module to stop playing the voice prompt, and can control the power part of the vehicle (electric vehicle) to be powered on.
[0033] In a possible implementation, the human body sensing module is a seat sensing button installed under a seat cushion of the vehicle.
[0034] In a possible implementation, the seat sensing button is connected in series between a power source of the vehicle and a power interface of an on-board device.
[0035] In one possible implementation, the second control module includes a third normally open contact and a first normally closed contact; the third normally open contact is connected to the vehicle control circuit to control the on and off of the power supply of the vehicle power part; the first normally closed contact is connected to the voice prompt module working circuit to control the on and off of the voice prompt module working circuit.
[0036] In a possible implementation, the third normally open contact is a normally open contact with delayed disconnection.
[0037] During riding, the second control module will continue to judge whether the rider has worn a helmet based on the signal received by the wireless communication transmission module. If it is determined that the rider has worn a helmet, the second control module will control the power supply of the vehicle power part through the third normally open contact. If it is determined that the rider has not worn a helmet, the second control module will control the power supply of the vehicle power part through the third normally open contact. To avoid this, by using a normally open contact with delayed disconnection, the vehicle-mounted device will not immediately disconnect the power supply of the vehicle power part when the signal sent by the smart helmet is not received. This can avoid the second control module's misjudgment that the vehicle is immediately powered off when the helmet-transmitted signal encounters interference or jitter, thereby enhancing the anti-interference ability.
[0038] In a possible implementation, the vehicle-mounted device further includes a wireless charging transmitter module for wirelessly charging the smart helmet.
[0039] In a possible implementation, the vehicle-mounted device further includes a second signal indication circuit; the second signal indication circuit includes a second indicator light (a red indicator light may be used) electrically connected to the second control module, for indicating that the vehicle-mounted device is powered on.
[0040] In a possible implementation, the second signal indication circuit includes a third indicator light electrically connected to the second control module, and is used to indicate whether the wireless communication receiving module receives signals normally.
[0041] When the vehicle is powered on, the on-board device starts. When someone sits on the vehicle seat, the seat sensor button is turned on, and the on-board device automatically powers on. If the signal indicating that the "helmet is worn" is not received, the voice prompt module issues a voice reminder "Please wear a helmet", and the voice reminder will be interrupted intermittently. When the rider does not wear a helmet, the power supply of the vehicle power part is disconnected through the normally open contact of the relay, so that the purpose of not being able to drive without a helmet is achieved. Only when the rider wears a helmet and the on-board part receives the signal from the helmet indicating that the "helmet is worn", the vehicle can be started.
[0042] When the smart helmet does not sense a human body, the first indicator light will not light up. When it senses a human body, the first indicator light will flash.
[0043] When the first human body sensing module and the helmet strap pin detection module detect that the rider has put on the helmet, the wireless communication transmission module sends a signal indicating that the "helmet is worn" to the vehicle-mounted device; the voice prompt of the vehicle-mounted device will automatically stop, and the power supply of the vehicle power part will automatically turn on, and the vehicle can start normally. After the wireless communication receiving module of the vehicle-mounted device receives the signal, the third indicator light will flash, indicating that the signal is received normally.
[0044] Beneficial effects:
[0045] The utility model can be used to remind riders to wear helmets, thereby enhancing the safety of riders. BRIEF DESCRIPTION OF THE DRAWINGS
