[0002] With the increasing popularity of cycling and advancements in bicycle technology, cycling safety has gradually become a focus of public attention. Especially during road and mountain biking, users frequently need to maintain control of the handlebars to ensure stable and safe riding. However, many cyclists may take one or both hands off the handlebars during cycling due to various factors, such as fatigue, answering calls, or other activities. This not only increases the risk of riding accidents, but can also lead to serious traffic accidents. Traditional cycling safety devices mostly focus on speed detection or direction control, lack real-time monitoring of the user's hand position, and have difficulty distinguishing between one-handed and two-handed situations.

[0027] Embodiment:

[0028] Please refer to Figure 1 The utility model provides a technical scheme:

[0029] A handlebar off-hand detection device, comprising: a sensing module, a timing module, a first logic module, a second logic module, a rotating speed detection module, a first alarm module, a third logic module, and a second alarm module.

[0030] The sensing module comprises a first detection unit and a second detection unit, which are respectively installed on the left and right handlebars of the vehicle. Both the first detection unit and the second detection unit adopt a pressure sensor, and the specific model can adopt a force-sensitive resistor sensor of the FSR400 series. This force-sensitive resistor sensor is a thin-film pressure sensor, which has the advantages of small size and high sensitivity, and is very suitable for installation on the handlebar and generates a high level when the handlebar is subjected to pressure. By installing independent pressure sensors on the left and right handlebars, the left and right hands of the user can be detected separately to determine whether they are away from the handlebars.

[0031] The timing module comprises a first timing unit and a second timing unit, the first timing unit is electrically connected with the first detection unit, and the second timing unit is electrically connected with the second detection unit. Both the first timing unit and the second timing unit adopt a digital timing module, and the specific model can adopt a microcontroller of the STM32L031 F6P6 series. This controller is a low-power 32-bit ARM Cortex-M0+ microcontroller, which integrates multiple timer modules and can be used to realize two independent timing functions. Therefore, it can be used to separately count the duration of the first detection unit and the second detection unit being at a low level, and generate a high level when the duration exceeds a preset time threshold. By setting the first and second timing units to be connected with the first and second detection units respectively, the conditions of the left and right handlebars can be judged separately. Specifically, since the first and second timing units count the duration of the first and second detection units being at a low level, when the vehicle is not ridden for a long time, the first and second detection units are both at a low level, and the outputs of the first and second timing units are both high. When the user is riding, holds the left and right handlebars, the first and second detection units are both at a high level, and the outputs of the first and second timing units are both low. If the user leaves one hand during riding, and the time of leaving the handlebar exceeds the time threshold, the output levels of the first and second timing units will be high and low; similarly, if the user leaves both hands during riding, the output levels of the first and second timing units will be both high. It can be understood that the comparison of the preset threshold is a mature existing technology, and the method is not improved, so it is not described in detail here.

[0032] The two inputs of the first logic module are electrically connected with the first timing unit and the second timing unit respectively, and the output of the first logic module is electrically connected with one of the inputs of the second logic module. The first logic module is an AND gate, and the specific model can adopt an AND gate integrated chip of 74HC08 series, and multiple AND gate functions can be realized in a small package. The first logic module is used to judge the pressure conditions of the left and right handlebars through the first and second timing units. When the user holds the handlebar with one hand, the output levels of the first and second timing units are high and low respectively, and the output of the first logic module is low. When the vehicle is not ridden or the user holds the handlebar with both hands, the output levels of the first and second timing units are both high, and the output of the first logic module is high.

[0033] The other input of the second logic module is electrically connected with the speed detection module, and the output of the second logic module is electrically connected with the first alarm module. The speed detection module is installed on the main shaft of the wheel. The second logic module also adopts an AND gate integrated chip of 74HC08 series. The speed detection module includes a speed sensor and a microcontroller connected in series. The speed sensor is used to detect the speed of the wheel, and the specific model can adopt a Honeywell 1GT101 DC Hall effect sensor. The microcontroller is used to generate a high level when the speed of the wheel exceeds a preset speed threshold, and the specific model can adopt an STM32L031F6P6 microcontroller. The first alarm module can be composed of a piezoelectric buzzer of PUI Audio AS07004PO-SB-R model and a flashing LED warning light. The piezoelectric buzzer of this model has the characteristics of small size and large volume, and is used to issue obvious sound and light alarms. That is, the function of the speed detection module is to detect whether the vehicle is in a riding state. When the vehicle is in a riding state, the speed sensor detects the speed of the wheel, so that the microcontroller generates a high level, and vice versa. Therefore, by setting the second logic module and connecting the first logic module and the speed detection module to the inputs of the second logic module, the two different application scenarios of the vehicle being not ridden and the user holding the handlebar with both hands can be further distinguished. Specifically, when the vehicle is not ridden, the output levels of the first and second timing units are both high, the output of the first logic module is high, but the speed detection module generates a low level, so the output of the second logic module is low, and the first alarm module does not make a sound. When the user holds the handlebar with both hands, the output levels of the first and second timing units are both high, the output of the first logic module is high, and the speed detection module generates a high level, so the output of the second logic module is high, and the first alarm module emits a loud sound and flashing warning light to remind the user not to hold the handlebar with both hands and pay attention to safety.

[0034] The two input ends of the third logic module are electrically connected with the first timing unit and the second timing unit respectively, and the output end of the third logic module is electrically connected with the second alarm module. The third logic module is an exclusive-OR gate, and a specific model can adopt a 74HC86 exclusive-OR gate integrated chip. The second alarm module can adopt a Mallory Sona lert SC628T type alarm, which can adopt an alarm with smaller power than the first alarm module, for emitting a sound alarm. When and only when the user holds the handle with one hand, the output levels of the first and second timing units are high and low respectively, at this time, the output of the third logic module is high, and the second alarm module emits a smaller sound to remind the user not to hold the handle with one hand and pay attention to safety. This is because the risk of holding the handle with one hand is smaller than that of holding the handle with two hands, and therefore, the sound alarm and the sound and light combined alarm are distinguished to reflect different risk levels.

[0035] The utility model also provides a handle, including handle of the above -mentioned and rubber handle, and handle of the above -mentioned is installed on rubber handle.

[0036] The utility model also provides a vehicle, vehicle includes vehicle body, handle, handle is installed on vehicle body, and handle adopts handle of the above -mentioned of the vehicle.

[0037] In summary, when the vehicle is not ridden, the first alarm module and the second alarm module do not emit an alarm. When the vehicle is ridden and the user holds the handle with one hand, the second alarm module emits a smaller sound to remind the user. When the vehicle is ridden and the user holds the handle with two hands, the first alarm module emits a larger sound, and the flashing warning light is used to remind the user together.

[0038] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0039] The above-described embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, some modifications and improvements can be made, which are within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
