[0006] Optionally, the helmet wearing detection system also includes: a second power supply module and a switch module built into the helmet, wherein: the switch module has a first end coupled to the voltage output end of the second power supply module, a second end coupled to the second sensing device, and a control end coupled to the controller; it is turned on in response to receiving a conduction control signal; and the controller outputs the conduction control signal to the control end of the switch module in response to receiving the first sensing signal.

[0007] Optionally, the helmet wearing detection system also includes: a helmet anti-theft wire, one end of which is coupled to the controller, and the other end of which is coupled to the switch module in the helmet; the helmet anti-theft wire has a built-in cable, and the control end of the switch module is coupled to the controller through the cable in the helmet anti-theft wire.

[0008] Optionally, the controller is also coupled to the vehicle lock control module of the electric bicycle, and in response to determining that the driver is wearing a helmet, outputs an unlocking control signal to the vehicle lock control module; and in response to determining that the driver is not wearing a helmet, outputs a locking maintenance signal to the vehicle lock control module.

[0009] Optionally, the helmet wearing detection system also includes: a forced unlocking module, which is arranged on the bracket and coupled to the controller; the forced unlocking module outputs a forced unlocking signal to the controller when the continuous triggering time reaches a preset time; the controller, in response to receiving the forced unlocking signal, outputs an unlocking control signal to the lock control module of the electric bicycle.

[0011] Optionally, the first power module includes a solar panel, and the solar panel is arranged on the outer surface of the bottom of the basket of the electric bicycle.

[0012] Optionally, the helmet wearing detection system further includes: a helmet anti-theft module, which is disposed in the basket of the electric bicycle and locks the helmet when the helmet is placed in the basket.

[0013] Optionally, the angle of the bracket is adjustable.

[0014] An embodiment of the utility model further provides an electric bicycle, comprising any one of the above-mentioned helmet wearing detection systems.

[0015] Compared with the prior art, the technical solution of the utility model has the following advantages:

[0016] When the first sensing device detects that there is a driver on the seat, a first sensing signal is output. When the second sensing device detects that there is a human body in the hemispherical cavity of the helmet, a second sensing signal is output. The controller of the helmet wearing detection system receives the first sensing signal and the second sensing signal and determines that the driver is wearing a helmet. In this way, it is possible to accurately detect whether the driver of the electric bicycle is wearing a helmet.

[0017] Furthermore, after receiving the first sensing signal, the controller outputs a conduction control signal to the switch module to control the switch module to conduct, so that the second power module supplies power to the second sensing device.

Thus, the vehicle lock is unlocked only after the driver wears a helmet, thereby improving the driver's safety during the driving of the electric bicycle.

[0020] Furthermore, if the controller detects that the driver is not wearing a helmet, it can output a voice playback control signal to the voice playback module. The voice playback module receives the voice playback control signal and plays a preset voice to remind the driver to wear a helmet.

[0021] Furthermore, the helmet wearing detection system may also include a forced unlocking module.

In some special scenarios, such as when the helmet is lost or damaged, the vehicle lock can also be unlocked normally.

[0022] In addition, the helmet wearing detection system may further include a helmet anti-theft module, which is arranged in the basket of the electric bicycle. When the helmet is not in use, the helmet can be locked in the basket by the helmet anti-theft module to prevent the helmet from being lost. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In real life, some drivers do not develop the good habit of wearing helmets when riding electric bicycles. During the driving of electric bicycles, if there is a collision or fall, it is easy to cause head injuries to the driver. However, in the prior art, there is a lack of solutions for detecting whether the driver is wearing a helmet.

[0027] In the embodiment of the utility model, when the first sensing device detects that there is a driver on the seat, a first sensing signal is output, and when the second sensing device detects that there is a human body in the hemispherical cavity of the helmet, a second sensing signal is output. The controller of the helmet wearing detection system receives the first sensing signal and the second sensing signal and determines that the driver has worn a helmet. In this way, it is possible to accurately detect whether the driver of the electric bicycle is wearing a helmet.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] The present invention provides a helmet wearing detection system suitable for electric bicycles. Figure 1 , a structural schematic diagram of a helmet wearing detection system in an embodiment of the utility model is given.

[0030] like Figure 2 As shown, a schematic diagram of a handlebar of an electric bicycle in an embodiment of the utility model is given. The handlebar of the electric bicycle includes a handlebar body 1, a brake handle 2 and a rotary switch 3. A bracket 4 is installed on the handlebar body 1, and a first sensing device 12 is installed on the bracket 4. The bracket 4 can be fixed on the handlebar body 1 by means of snap connection or screw connection.

[0031] In the embodiment of the utility model, the helmet wearing detection system includes: a controller 11 , a first sensing device 12 , a second sensing device 13 , and a first power module 14 .

[0032] In a specific implementation, the first sensing device 12 can be installed on the bracket 4, and the bracket 4 can be installed on the handlebar body 1 of the electric bicycle.

[0033] The height and angle of the bracket are adjustable. By adjusting the height and angle of the bracket 4 , the height and angle of the first sensing device 12 can be adjusted, and then the detection height and detection angle of the first sensing device 12 can be adjusted.

[0034] In a specific implementation, the first sensing device 12 can be coupled to the controller 11, and can detect whether there is a driver on the seat of the electric bicycle. If the first sensing device 12 detects that there is a driver on the seat of the electric bicycle, the first sensing device 12 can generate a first sensing signal and output it to the controller 11. If the first sensing device 12 detects that there is no driver on the seat of the electric bicycle, the first sensing device 12 does not need to generate the first sensing signal, that is, the controller will not receive the first sensing signal.

[0035] In a specific implementation, the sensing direction of the first sensing device 12 may face the seat of the electric bicycle to detect whether there is a driver on the seat of the electric bicycle.

[0036] In some embodiments, the first sensing device 12 may be an infrared thermal imaging sensor, which may obtain an infrared image above the seat of the electric bicycle and determine whether there is a driver above the seat of the electric bicycle based on the temperature distribution in the infrared image.

[0037] For example, the infrared thermal imaging sensor detects a heat source with a human outline above the seat of the electric bicycle in the infrared image, thereby determining that there is a driver above the seat of the electric bicycle.

[0038] In a specific implementation, the second sensing device 13 can be built into the helmet, and can detect whether there is a human body in the hemispherical cavity of the helmet. If the second sensing device 13 detects that there is a human body in the hemispherical cavity of the helmet, it can be determined that the helmet is worn by the driver, and a second sensing signal can be generated and output to the controller 11. If the second sensing device 13 detects that there is no human body in the hemispherical cavity of the helmet, there is no need to generate a second sensing signal.

[0039] In some embodiments, the second sensing device 13 may be a pressure sensor. When the driver wears the helmet, the pressure sensor built into the helmet can detect the pressure change, and thus determine that there is a human body in the hemispherical cavity of the helmet.

[0040] In a specific implementation, after receiving the first sensing signal and the second sensing signal, the controller 11 can determine that the driver has finished wearing the helmet.

[0041] If the controller 11 only receives the first sensing signal but does not receive the second sensing signal, the controller 11 may determine that the driver is not wearing a helmet.

[0042] In a specific implementation, the controller 11 and the first sensing device 12 may be integrated into one device. Figure 2 As shown, the controller 11 and the first sensing device 12 can be integrated in the device 5. The device 5 is fixed on the bracket 4 by means of snap connection or screw connection.

[0043] In actual application scenarios, the driver can wear a helmet first and then sit on the seat of the electric bicycle. Alternatively, the driver can sit on the seat of the electric bicycle first and then wear a helmet. There may be a certain time difference between the first sensing signal and the second sensing signal received by the controller 11.

[0044] In the embodiment of the utility model, when the controller 11 receives the first sensing signal and the second sensing signal and detects that the time difference between the first time point of receiving the first sensing signal and the second time point of receiving the second sensing signal is within the time range, it can be determined that the driver is wearing a helmet.

[0045] The above duration range may be preset, for example, the duration range is 1s to 20s.

[0046] In the embodiment of the utility model, the controller 11 can also be coupled to the lock control module 21 of the electric bicycle. When the controller 11 receives the first sensing signal and the second sensing signal and determines that the driver has worn a helmet, it can generate an unlocking control signal and output it to the lock control module 21 of the electric bicycle. When the lock control module 21 receives the unlocking control signal, the lock can be unlocked, and the driver can turn the electric switch of the electric bicycle to start the electric bicycle.

[0047] If the controller 11 does not receive the first sensing signal / the second sensing signal, the controller 11 determines that the driver is not wearing a helmet. In this scenario, the controller 11 can generate a lock maintenance signal and output the lock maintenance signal to the vehicle lock control module 21. The vehicle lock control module 21 receives the lock maintenance signal and maintains the locked state of the vehicle lock.

[0048] That is to say, when the controller 11 detects that the driver is wearing a helmet, the controller 11 controls the lock control module 21 to unlock the lock, and the driver can drive the electric bicycle normally. When the controller 11 detects that the driver is not wearing a helmet, the lock control module 21 is controlled not to unlock the lock, and the driver cannot drive the electric bicycle. Therefore, the driver can drive the electric bicycle only when wearing a helmet, which can improve the safety factor of the driver during driving.

[0049] In some embodiments, the controller 11 determines that the driver is not wearing a helmet, and does not need to generate and output any form of control signal (such as the lock maintenance signal mentioned above). The vehicle lock control module 21 does not detect the control signal output by the controller 11, and maintains the locked state of the vehicle lock.

[0050] Reference Figure 3 , a structural schematic diagram of another helmet wearing detection system in an embodiment of the utility model is given.

[0051] In an embodiment of the utility model, the helmet wearing detection system may further include a voice playing module 15. The voice playing module 15 may be arranged on a bracket, and the voice playing module 15 is coupled to the controller 11. When the controller 11 determines that the driver is not wearing a helmet, the controller 11 may output a voice playing control signal to the voice playing module 15. The voice playing module 15 receives the voice playing control signal and may play a preset voice to remind the driver to wear a helmet.

[0052] For example, the voice playing module 15 receives the voice playing control signal and plays the following voice: "For your driving safety, please wear a helmet correctly." The voice playing module 15 can effectively remind the driver to wear a helmet.

[0053] In an embodiment of the utility model, the helmet wearing detection system may further include a forced unlocking module 16. The forced unlocking module 16 may be arranged on a bracket. When the forced unlocking module 16 is continuously triggered by the driver and the duration of the continuous triggering reaches a preset duration, a forced unlocking signal may be generated and output to the controller 11. The controller 11 receives the forced unlocking signal, determines that the driver has a demand for forced unlocking, and may output an unlocking control signal to the vehicle lock control module 21 to unlock the vehicle lock.

[0054] The preset duration may be 5 seconds, 10 seconds or other values.

[0055] A forced unlocking module 16 is provided so that the driver can also unlock the lock of the electric bicycle in special circumstances such as when the helmet is lost or damaged.

[0056] In some embodiments, the voice playing module 15 , the forced unlocking module 16 , etc. may also be integrated into the device 5 .

[0057] In actual application scenarios, some drivers do not wear helmets correctly when riding electric bicycles, even though they wear helmets. For example, in hot weather, some drivers do not buckle the buckle ring in the buckle groove.

[0058] In the embodiment of the utility model, a third sensing device may be further provided in the buckle of the helmet. When the third sensing device detects that the buckle ring is buckled in the buckle groove, a third sensing signal is generated and output. The controller 11 determines that the driver has worn the helmet only after receiving the first sensing signal, the second sensing signal and the third sensing signal.

[0059] In a specific implementation, the third sensing device may be disposed in the buckle slot. The third sensing device may communicate with the controller 11 via wired or wireless means.

[0060] In some embodiments, the third sensing device may be coupled to the controller 11 via a cable. In other embodiments, the third sensing device may communicate with the controller 11 via a Bluetooth module.

[0061] The third sensing device may be a pressure sensor. When the buckle ring is inserted into the buckle groove, the pressure sensor detects a change in pressure. The pressure sensor may output a detected pressure signal. When the controller 11 detects a pressure signal with a changed amplitude, it is determined that the third sensing signal is received.

[0062] The third sensing device is provided to determine whether the driver has buckled the buckle ring of the helmet into the buckle groove, and further determine whether the driver is wearing the helmet correctly.

[0063] In the embodiment of the utility model, the helmet wearing detection system may further include a second power supply module 17 and a switch module 18, wherein:

[0064] A first end of the switch module 18 is coupled to a voltage output end of the second power module 17 , a second end of the switch module 18 is coupled to the second induction device 13 , and a control end of the switch module 18 is coupled to the controller 11 ;

[0065] The controller 11 is further adapted to generate a conduction control signal after receiving the first sensing signal, and output the conduction control signal to the control terminal of the switch module 18 .

[0066] When the control terminal inputs the conduction control signal, the switch module 18 is turned on, a path is formed between the second power module 17 and the second induction device 13 , and the second power module 17 supplies power to the second induction device 13 .

[0067] Therefore, after receiving the first sensing signal, the controller 11 outputs a conduction control signal to the switch module 18 to control the switch module 18 to be turned on, so that the second power module 17 supplies power to the second sensing device 13. The second sensing device 13 does not need to be in a working state for a long time, which can reduce power consumption and extend the service life of the second power module 17.

[0068] In an embodiment of the utility model, the helmet wearing detection system may further include: a helmet anti-theft line. One end of the helmet anti-theft line may be coupled to the controller 11, and the other end of the helmet anti-theft line may be coupled to the helmet. By setting the helmet anti-theft line, the helmet can be effectively prevented from being lost.

[0069] In a specific implementation, a cable is built into the helmet anti-theft line. One end of the cable is coupled to the controller 11, and the other end of the cable is coupled to the control end of the switch module 18. The conduction control signal generated by the controller 11 can be output to the control end of the switch module 18 via the cable. The built-in cable in the helmet anti-theft line can realize the communication between the controller 11 and the switch module 18.

[0070] In an embodiment of the utility model, the helmet wearing detection system may further include a helmet anti-theft module. The helmet anti-theft module may be arranged in the basket of the electric bicycle. When the driver does not need to drive the electric bicycle, the helmet may be locked by the helmet anti-theft module to avoid the helmet being lost.

[0071] In some embodiments, the helmet anti-theft module may include a card holder. When the driver is not using the electric bicycle, the helmet can be placed in the card holder and locked.

[0072] In the embodiment of the utility model, the first power module 14 can be coupled to the battery of the electric bicycle. The first power module 14 includes a direct current to direct current (DC-DC) unit. Through the DC-DC unit, the first power module 14 can output the operating voltage required by the controller 11 and the like.

[0073] For example, the output voltage of the battery of the electric bicycle is 48V, and through the DC-DC module, the first power module 14 outputs a voltage of 5V.

[0074] In a specific implementation, the first power module 14 may include a solar panel, which may be disposed on the outer surface of the bottom of the basket of the electric bicycle. The solar panel generates electricity to supply power to the controller 11, the first induction module, etc.

[0075] An embodiment of the utility model further provides an electric bicycle, comprising the helmet wearing detection system provided by any of the above embodiments.

[0076] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
