[0031] The following is a further detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "inner", "middle", "left", "right" and "one" used in this specification are only used to facilitate the description and are not used to limit the scope of the present invention. The changes or adjustments in their relative relationships shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0032] A reminder device for regulating safe driving of electric vehicles, such as Figures 1 to 3 As shown, it includes a helmet, a helmet detection circuit and an electric vehicle control system. The helmet detection circuit is installed on the helmet, and the helmet detection circuit communicates wirelessly with the electric vehicle control system. When wearing a helmet, the helmet detection circuit detects whether the helmet is worn in a standard manner through corresponding sensors. The standard standard is whether the helmet is worn on the head, whether the chin strap is normally fastened when the helmet is worn, whether the chin strap is appropriately tight, and whether the posture is standard when the helmet is worn, thereby generating corresponding sensor signals. When the sensor signal is abnormal, a corresponding sensor abnormal signal is generated, and when the sensor signal is normal, a corresponding sensor normal signal is generated; the helmet detection circuit transmits the detected sensor abnormal signal or sensor normal signal to the electric vehicle control system by wireless means, and the electric vehicle control system receives the sensor abnormal signal or sensor normal signal, and further controls the opening and closing of the electric vehicle switch (the electric vehicle switch is the electric vehicle handle switch starter).

[0033] Based on the above introduction to the functions of the helmet, the helmet detection circuit and the electric vehicle control system in the reminder device of the utility model, the structures of the helmet, the helmet detection circuit and the electric vehicle control system are further introduced below.

[0034] like Figure 1 As shown, the helmet comprises a helmet shell 1 and a first chin strap 11 and a second chin strap 12 mounted on the helmet shell 1. The first chin strap 11 is provided with a length adjusting member 17. The length adjusting member 17 can adopt a structure that can achieve length adjustment, such as a belt-type adjusting buckle or a rope tightening belt. A fastening member 13 is provided at the end of the first chin strap 11. The fastening member 13 has a matching hole for buckle matching. A buckle tongue 14 is provided at the end of the second chin strap 12. The buckle tongue 14 is buckled and matched with the matching hole of the fastening member 13 to improve the firmness of wearing the helmet.

[0035] Among them, the first chin strap 11 and the second chin strap 12 are respectively provided with a first metal wire 15 and a second metal wire 16, and the surfaces of the first metal wire 15 and the second metal are both provided with an insulating layer. The first metal wire 15 and the second metal wire 16 are respectively electrically connected to the positive and negative poles of the power supply of the helmet detection circuit. The first metal wire 15 extends to the fastening member 13, and the second metal wire 16 extends to the buckle tongue 14. When the buckle tongue 14 is buckled with the fastening member 13, the first metal wire 15 and the second metal wire 16 are electrically connected, which facilitates the subsequent detection of whether the buckle tongue 14 and the fastening member 13 are well matched.

[0036] like Figures 1 to 3 As shown, the helmet detection circuit includes a detection circuit 2 and a human detection sensor 21, a posture sensor 22, a chin strap sensor, a signal transmitter 25, a first prompting member 26, a solar panel 27 and a power supply device electrically connected to the detection circuit 2. Among them, the detection circuit 2 can use a control chip such as a single-chip microcomputer; the signal transmitter 25 is used to wirelessly transmit the sensor signals of the human detection sensor 21, the posture sensor 22, and the chin strap sensor received by the detection circuit 2 to the electric vehicle control system, and the wireless transmission method can use WiFi, Bluetooth, 4G, 5G and other wireless transmission methods.

[0037] The human body detection sensor 21 is arranged on the inner top surface of the helmet shell 1, and is used to sense whether the helmet is worn on the human head. The detection circuit 2 is used to generate a sensor normal signal or a sensor abnormal signal about the detection situation of the human body detection sensor 21, so that the first prompt member 26 can make a prompt in time. At the same time, the sensor normal signal or the sensor abnormal signal is wirelessly transmitted to the electric vehicle control system through the signal transmitter 25, and the start-up of the electric vehicle ignition switch is controlled.

[0038] The posture sensor 22 is arranged on the side of the helmet shell 1. The posture sensor 22 adopts a horizontality sensor or a verticality sensor. The posture sensor 22 detects the horizontality range or verticality range of the helmet, and then determines whether the helmet is worn correctly, such as detecting whether the helmet is worn in an irregular and unsafe manner such as wearing it backwards, up and down. At the same time, the detection circuit 2 is used to generate a sensor normal signal or a sensor abnormal signal about the detection situation of the posture sensor 22, so that the first prompting member 26 can make prompts in time, and at the same time, the sensor normal signal or the sensor abnormal signal is wirelessly transmitted to the electric vehicle control system through the signal transmitter 25, and the start-up of the electric vehicle switch is controlled.

[0039] The chin strap sensor includes a tightness sensor 23 and a current detection sensor 24 , and both the tightness sensor 23 and the current detection sensor 24 are electrically connected to the detection circuit 2 .

[0040] The tension sensor 23 is arranged on the first chin strap 11 or the second chin strap 12, and is used to sense the overall tightness of the second chin strap 12 when it is buckled with the fastening piece 13 of the first chin strap 11 through the buckle tongue 14. When the first chin strap 11 and the second chin strap 12 are buckled with the fastening piece 13 through the buckle tongue 14 to form a whole, the tension sensor 23 is used to detect whether the first chin strap 11 and the second chin strap 12 are close to the face or the jaw of the person. When the first chin strap 11 and the second chin strap 12 are loose, the detection circuit 2 generates a corresponding sensor abnormality signal through the tension sensor 23, so that the first prompting member 26 can make prompts in time, so that the user can adjust the length adjustment member 17 to make the first chin strap 11 and the second chin strap 12 fit the face or the jaw of the person normally. At the same time, the sensor abnormality signal is wirelessly transmitted to the electric vehicle control system through the signal transmitter 25, and the start of the electric vehicle ignition is controlled.

[0041] The first metal wire 15 and the second metal wire 16 are specifically electrically connected to the positive and negative poles of the power supply of the detection circuit 2. The current detection sensor 24 is electrically connected to the first metal wire 15 or the second metal wire 16, and is used to detect the effectiveness of the buckle tongue 14 and the fastening member 13. The current detection sensor 24 can use a display light. When the buckle and the fastening member 13 are well buckled, the current detection sensor 24 is powered on, and the display light is illuminated. Otherwise, the display light is not illuminated. The detection circuit 2 generates a corresponding sensor normal signal or sensor abnormal signal based on the detection situation of the current detection sensor 24, so that the first prompt member 26 can give a prompt in time. At the same time, the sensor normal signal or sensor abnormal signal is wirelessly transmitted to the electric vehicle control system through the signal transmitter 25, and the start-up situation of the electric vehicle ignition is controlled.

[0042] The first prompting member 26 is arranged on the side of the helmet shell 1. The first prompting member 26 can be a speaker or a prompt light to prompt whether the helmet is worn correctly. When the sensor signals of the human body detection sensor 21, the posture sensor 22, and the chin strap sensor are abnormal (for example, the human body detection sensor 21 does not detect the human head, the posture sensor 22 detects that the helmet wearing posture is incorrect, the tightness sensor 23 detects that the overall tightness of the first chin strap 11 and the second chin strap 12 that match each other is too loose, and the current detection sensor 24 detects that the buckle tongue 14 of the second chin strap 12 does not match well with the fastening member 13 of the first chin strap 11), the first prompting member 26 issues a reminder or warning, which can be a speaker sounding an alarm or a prompt light emitting light.

[0043] The positive and negative electrodes of the power supply are electrically connected to the positive and negative electrodes of the power supply of the detection circuit 2 respectively. The solar panel 27 is arranged on the surface of the helmet, and the two ends of the solar panel 27 are electrically connected to the positive and negative electrodes of the power supply respectively, so that the solar panel 27 can receive sunlight, and after converting the sunlight energy into electrical energy, the electrical energy is transmitted and stored in the power supply, so that the power supply can power the detection circuit 2.

[0044] like Figures 1 to 3 As shown, the electric vehicle control system is installed on the electric vehicle, and the electric vehicle control system includes a control circuit 3 and a signal receiver 31 electrically connected to the control circuit 3, an electric vehicle controller 32, and a second prompting member 33. Among them, the signal receiver 31 is used to receive the sensor normal signal or the sensor abnormal signal wirelessly transmitted by the signal transmitter 25.

[0045] After the control circuit 3 receives the normal sensor signal or the abnormal sensor signal wirelessly transmitted by the signal transmitter 25 through the signal receiver 31, when the normal sensor signal is received, the control circuit 3 transmits the switch control signal to the electric vehicle controller 32, and the electric vehicle controller 32 transmits the switch control signal to the electric vehicle switch to control the opening of the electric vehicle switch; when the abnormal sensor signal is received, the control circuit 3 transmits the switch control signal to the electric vehicle controller 32, and the electric vehicle controller 32 transmits the switch control signal to the electric vehicle switch to control the closing of the electric vehicle switch, and the second prompt member 33 will also issue a corresponding prompt or warning.

[0046] Among them, the electric vehicle controller 32 adopts a relay, which is used to receive the electric vehicle's front lock on / off state signal and the electric door control signal of the control circuit 3. The relay receives the electric vehicle's front lock on / off state signal and transmits it to the control circuit 3 to determine whether the electric vehicle is in a ready-to-start state. When the control circuit 3 obtains the electric vehicle's front lock on / off state signal through the electric vehicle's front lock that the electric vehicle's front lock has been opened and is in a ready-to-start state, it sends the electric door control signal to the electric vehicle's electric door through the relay and controls the electric door of the electric vehicle to start or close; when it is obtained that the electric vehicle's front lock is not opened, the electric door control signal is not sent to the electric door of the electric vehicle.

[0047] In addition, the second prompting member 33 can be a speaker, a warning light or a display screen. When the control circuit 3 receives an abnormal sensor signal, the second prompting member 33 issues a reminder or warning. Correspondingly, the speaker may issue a warning, the warning light may light up, and the display screen may display specific abnormal information. The abnormal information may be that the human body detection sensor 21 does not detect the human head, the posture sensor 22 detects that the helmet wearing posture is incorrect, the tightness sensor 23 detects that the overall tightness of the first chin strap 11 and the second chin strap 12 is too loose, and the current detection sensor 24 detects that the buckle tongue 14 of the second chin strap 12 is not well matched with the fastening member 13 of the first chin strap 11.

[0048] Working principle: When the user turns on the front lock of the electric vehicle and wears the helmet, and waits to turn on the electric vehicle ignition (electric vehicle handle ignition starter), the helmet detection circuit uses the human body detection sensor 21, the posture sensor 22 and the chin strap sensor to detect whether the helmet is worn properly as follows: the human body detection sensor 21 detects whether the human head is in the helmet, the posture sensor 22 detects whether the helmet wearing posture is incorrect, the tightness sensor 23 detects whether the overall tightness of the first chin strap 11 and the second chin strap 12 that cooperate with each other is within the appropriate tightness range, the current detection sensor 24 detects whether the buckle tongue 14 of the second chin strap 12 is well matched with the fastener 13 of the first chin strap 11, the human body detection sensor 21, the posture sensor 22 and the chin strap The belt sensor transmits the corresponding sensor signal to the detection circuit 2, and the detection circuit 2 is used to determine whether the received sensor signal is normal or abnormal, and forms a sensor abnormal signal or a sensor normal signal. If the sensor signal is abnormal, the first prompt element 26 issues a prompt or a warning; at the same time, the signal transmitter 25 of the detection circuit 2 wirelessly transmits the sensor abnormal signal or the sensor normal signal to the signal receiver 31 of the control circuit 3, and the control circuit 3 generates a corresponding switch control signal according to the received sensor abnormal signal or the sensor normal signal, and uses the electric vehicle controller 32 to send the switch control signal to the electric vehicle switch to control the opening and closing of the electric vehicle switch; wherein, if the control circuit 3 receives the sensor abnormal signal, a prompt or a warning is issued through the second display element.

[0049] The implementation methods of the utility model are not limited to this. According to the above content of the utility model, by using common technical knowledge and customary means in the field, without departing from the above basic technical ideas of the utility model, the utility model can also make other various forms of modification, replacement or combination, all of which fall within the scope of protection of the utility model.
