Description

Technical Field

[0001] The present invention relates to the technical field of automatic control, and in particular to a bicycle safety control device and method. Background Art

[0002] At present, bicycles are a convenient means of transportation and are widely used in daily life.

[0003] The applicant found that under certain circumstances, due to the negligence of the rider, the power switch was not turned off in time after the ride, and the power switch was turned intentionally or unintentionally by others, or the rider was not sitting on the bicycle seat (for example, after falling) and accidentally turned the power switch, which would cause the bicycle to run out of control, possibly causing damage to people or other objects, or even life-threatening. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a bicycle safety control device and method, which can prevent the bicycle from moving forward uncontrollably due to accidental turning of the handlebar switch when the bicycle is not in a riding state.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] A bicycle safety control device comprises a main controller, a battery module and a driving motor. The main controller is connected to and controls the battery module to supply power to the driving motor. The main controller is connected to a sensor module. The main controller is connected to a handlebar switch. The handlebar switch and the sensor module are connected in series.

[0007] Furthermore, the sensor module includes a plurality of sensors, and the plurality of sensors are connected in parallel.

[0008] Furthermore, the sensor includes a pressure sensor.

[0009] Furthermore, the sensor module is arranged above the seat.

[0010] Furthermore, the main controller is connected to a brake module.

[0011] Furthermore, the battery module includes a storage battery or a fuel cell, and the fuel cell includes a hydrogen energy fuel cell.

[0012] Furthermore, a bicycle safety control method comprises the following steps:

[0013] When the rider sits on the seat, the sensor module circuit is turned on;

[0014] S1: On the premise that the sensor module circuit is conductive, turn the ignition switch circuit on;

[0015] S2: The rider turns the handlebar switch;

[0016] S3: The main controller controls the battery module to supply power to the drive motor, and the drive motor rotates.

[0017] Furthermore, when the sensor module uses multiple sensors for detection, the main controller needs to detect that the circuits of two or more sensors are turned on before the main controller can control the drive motor to rotate according to the rotation of the throttle switch.

[0018] Furthermore, when the rider uses the brake module, the sensor module circuit is disconnected.

[0019] In summary, compared with the prior art, the above technical solution has the following beneficial effects:

[0020] (1) When the rider sits on the seat, the sensor module detects a pressure signal. At this time, the circuit of the sensor module is turned on and the rider is in a normal riding state. When the rider turns the handlebar switch, the main controller of the bicycle can control the battery module to supply power to the drive motor to drive the bicycle forward. On the contrary, when the rider is not sitting on the bicycle, such as forgetting to remove the key or accidentally falling down while riding, the handlebar switch may be turned unintentionally due to the rider falling down. However, since the sensor module does not detect the riding pressure signal, the rider is in a non-riding state. At this time, the main controller of the bicycle does not control the battery module to supply power to the drive motor, and the bicycle will not move forward, thereby ensuring the safety of the rider and other people around.

[0021] (2) When the main controller detects that the brake module is in use, the sensor module circuit is disconnected. At this time, regardless of whether the handlebar switch is turned, the main controller will not control the battery module to supply power to the drive motor. Only when the main controller does not detect that the brake module is in use, the handlebar switch is turned, and the main controller controls the battery module to supply power to the drive motor, thereby driving the bicycle forward.

[0022] (3) A pressure sensor is selected and installed above the seat. When the rider sits on the seat, the pressure sensor receives a pressure signal, and the resistance at both ends of the pressure sensor changes from infinite to conductive. The main controller of the bicycle determines whether the rider is sitting on the seat by detecting the conductive state of the pressure sensor.

[0023] (4) In order to increase the reliability and credibility of detection, multiple sensors are used for simultaneous detection. Multiple sensors are arranged above the seat. When the main controller of the bicycle detects that two or more sensors are turned on, it is considered that the current rider is sitting above the seat. According to the rotation range of the handlebar ignition switch, the main controller controls the battery module to supply power to the drive motor, causing the drive motor to rotate. This can greatly enhance the reliability and redundancy of the system and avoid misjudgment caused by false triggering of a single sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] The embodiment of the invention discloses a bicycle safety control device.

[0028] Reference Figure 1 and Figure 2 A bicycle safety control device includes a main controller, a battery module and a drive motor. The main controller is connected to and controls the battery module to supply power to the drive motor. The main controller of the bicycle can control the battery module to supply power to the drive motor to drive the bicycle forward.

[0029] The battery module includes a storage battery or a fuel cell. The fuel cell includes a hydrogen energy fuel cell. Through the electrochemical reaction of the hydrogen fuel cell, hydrogen and oxygen are combined to generate electricity to provide auxiliary power for riding. Among them, hydrogen energy, the chemical energy released by the chemical reaction of hydrogen and oxygen, is a secondary clean energy and is known as the "ultimate energy of the 21st century". Hydrogen mainly appears in the form of a chemical combination on the earth. It is the most widely distributed substance in the universe. It constitutes 75% of the mass of the universe and is a secondary energy source. Hydrogen energy is likely to become an important energy source on the world energy stage in the 21st century, and the production, storage, transportation and application technology of hydrogen will also become the focus of attention in the 21st century. Hydrogen has the characteristics of high combustion calorific value, which is 3 times that of gasoline, 3.9 times that of alcohol, and 4.5 times that of coke. The product of hydrogen combustion is water, which is the cleanest energy in the world. With abundant resources and sustainable development, hydrogen electric bicycles will also be one of the major trends of sustainable development in the future.

[0030] The main controller is connected to a sensor module, and the main controller is connected to a handlebar switch, and the handlebar switch and the sensor module are connected in series. When the rider sits on the seat, the sensor module detects a pressure signal, and the circuit of the sensor module is turned on, and the rider is in a normal riding state. When the rider turns the handlebar switch, the main controller of the bicycle can control the battery module to supply power to the drive motor to drive the bicycle forward; on the contrary, when the rider is not sitting on the bicycle, such as forgetting to remove the key, or accidentally falling down while riding, the handlebar switch may be turned unintentionally due to the rider falling down, but because the sensor module does not detect the riding pressure signal, it is in a non-riding state. At this time, the main controller of the bicycle does not control the battery module to supply power to the drive motor, and the bicycle will not move forward, thereby ensuring the safety of the rider and other surrounding people.

[0031] The sensor module is arranged above the seat. The sensor is preferably a pressure sensor. By installing the pressure sensor above the seat, when the rider sits above the seat, the pressure sensor receives a pressure signal, and the resistance at both ends of the pressure sensor changes from infinity to a conductive state. The main controller of the bicycle determines whether the rider is sitting on the seat by detecting the conductive state of the pressure sensor.

[0032] The sensor module includes several sensors, and several sensors are connected in parallel. In order to increase the reliability and credibility of detection, when multiple sensors are used for simultaneous detection, multiple sensors are arranged above the seat. When the main controller of the bicycle detects that two or more sensors are turned on, it is considered that the current rider has sat on the seat, and then according to the rotation range of the throttle switch, the main controller controls the battery module to supply power to the drive motor to rotate the drive motor, which can greatly enhance the reliability and redundancy of the system and avoid misjudgment caused by false triggering of a single sensor.

[0033] The main controller is connected to the brake module. When the main controller detects that the brake module is in use, the sensor module circuit is disconnected. At this time, regardless of whether the throttle switch is turned, the main controller will not control the battery module to supply power to the drive motor. Only when the main controller does not detect that the brake module is in use, the throttle switch is turned at this time, and the main controller controls the battery module to supply power to the drive motor, thereby driving the bicycle forward.

[0034] The implementation principle of a bicycle safety control device according to an embodiment of the present invention is as follows:

[0035] Whether the brake module is used is the premise of whether the sensor module circuit is conductive. If the brake module is used, the sensor module circuit is always in a non-conductive state. If the brake module is not used, the pressure signal is detected through the pressure sensor.

[0036] The sensor module is used to detect whether the rider is sitting on the seat. Through the pressure sensor, if the rider is detected to be sitting, the sensor module circuit is conductive. If the rider is not detected to be sitting, the sensor module circuit is not conductive and the resistance is infinite.

[0037] On the premise that the brake module is not in use and the sensor module circuit is connected, the rider turns the handlebar switch, and the main controller controls the battery module to supply power to the drive motor through the rotation angle of the handlebar switch, driving the motor to rotate, thereby achieving safer bicycle riding.

[0038] The embodiment of the invention discloses a bicycle safety control method.

[0039] Reference Figure 1 and Figure 2 , a bicycle safety control method, comprising the following steps:

[0040] When the rider sits on the seat, the sensor module circuit is turned on;

[0041] When the sensor module uses multiple sensors for detection, the main controller needs to detect that the circuits of two or more sensors are turned on before the main controller can control the drive motor to rotate according to the rotation of the throttle switch.

[0042] When the rider uses the brake module, the sensor module line is disconnected.

[0043] S1: On the premise that the sensor module circuit is conductive, the handlebar switch circuit is conductive.

[0044] S2: The rider turns the handlebar switch.

[0045] S3: The main controller controls the battery module to supply power to the drive motor, and the drive motor rotates.

[0046] The implementation principle of a bicycle safety control method according to an embodiment of the present invention is as follows:

[0047] Whether the brake module is used is the premise of whether the sensor module circuit is conductive. If the brake module is used, the sensor module circuit is always in a non-conductive state. If the brake module is not used, the pressure signal is detected through the pressure sensor.

[0048] The sensor module is used to detect whether the rider is sitting on the seat. Through the pressure sensor, if the rider is detected to be sitting, the sensor module circuit is conductive. If the rider is not detected to be sitting, the sensor module circuit is not conductive and the resistance is infinite.

[0049] On the premise that the brake module is not in use and the sensor module circuit is connected, the rider turns the handlebar switch, and the main controller controls the battery module to supply power to the drive motor through the rotation angle of the handlebar switch, driving the motor to rotate, thereby achieving safer bicycle riding.
