Please refer to Figure 1 and Figure 2, the seat cushion automatic lifting system of a bicycle provided by a preferred embodiment of the present invention mainly includes: a vehicle body 10, a detection module 30 and a control module 50.

The car body 10 has a vehicle frame 12 , two wheels 14 , two pedals 16 , a cushion 18 and a lifting device 20 . The two wheels 14 are arranged on the front and rear sides of the vehicle frame 12 . The two pedals 16 are respectively connected to the two cranks of the vehicle body 10, and are movably arranged on the left and right sides of the vehicle frame 12. The seat cushion 18 is located at the center of the frame 12 . The lifting device 20 is movably arranged under the seat cushion 18 of the vehicle body 10 , one end is connected to the seat cushion 18 , and the other end is connected to the vehicle frame 12 for adjusting the height of the seat cushion 18 . In this embodiment, the lifting device 20 is a pneumatic component driven by air pressure. In other embodiments, the lifting device 20 can be a hydraulic component driven by hydraulic pressure or an electronic component driven by electricity. The user rides on the seat cushion 18 and steps on the two pedals 16 to drive the two wheels 141 to rotate and move forward. The vehicle body 10 is a conventional structure, and its details are not repeated here.

The detection module 30 is installed on the vehicle body 10 to detect whether the vehicle body 10 is in a stopped state, and accordingly generate a corresponding stop signal; it can also detect whether the vehicle body 10 is in a moving state , and accordingly generate a corresponding mobile signal. Specifically, in this embodiment, the detection module 30 has a rotational speed sensing unit 32 , a pressure sensing unit 34 and two transmission units 36 .

The rotational speed sensing unit 32 calculates the rotational speed according to the change produced when one of the two wheels 14 rotates, so as to determine whether the vehicle body 10 is in a moving state. For example, in this embodiment, the rotational speed sensing unit 32 includes a Hall element and a magnet, wherein the Hall element can be arranged on the side of the axle of one of the wheels 14, and the magnet can be arranged on the corresponding wheel 14 on the side (such as on the spokes of the wheel). Therefore, when the user is riding, the wheel 14 starts to rotate, and then the Hall element detects the magnet, and generates a rotational speed signal according to the voltage change during detection. When the user is parking, the rotational speed signal is 0 or a very small value.

The pressure sensing unit 34 judges whether the user steps on the two pedals 16 according to the pressure change produced by the user stepping on one of the two pedals 16, so as to judge whether the user leaves the two pedals 16 due to the parking state. Wait for pedal 16. For example, in this embodiment, the pressure sensing unit 34 is a piezoresistive pressure sensor, embedded in one of the two pedals 16 of the vehicle body 10 or disposed on the surface. In this way, when the user steps on the pedal 16 , the pressure sensing unit 34 will produce a stress change, resulting in a change of the resistance value, so as to generate a pressure signal. When the user is parking, the pressure signal is 0 or a very small value.

In this embodiment, when the rotational speed signal is greater than a first predetermined value and the pressure signal is greater than a second predetermined value, it means that the vehicle body 10 is in a moving state, for example, the rotational speed is greater than 1 rpm or the pressure is greater than 0.01 atm. The signal and the pressure signal are the movement signal. When the speed signal is small When it is equal to the first predetermined value and the pressure signal is less than or equal to the second predetermined value, it means that the car body 10 is in a stopped state, for example, the speed is less than or equal to 1 rpm or the pressure is less than or equal to 0.01 atm. At this time, the speed signal and the pressure signal are for the stop signal. In another embodiment, the moving signal means that both the rotational speed signal and the pressure signal are greater than 0, and the stop signal means that both the rotational speed signal and the pressure signal are equal to 0.

The two transmission units 36 are respectively electrically connected to the rotation speed sensing unit 32 and the pressure sensing unit 34 for transmitting the generated movement signal or the stop signal to the control module 50 . The two transmission units 36 can have a wired or wireless transmission structure. In this embodiment, the two transmission units 36 are wireless transmission devices, and use WiFi, bluetooth, infrared or other equivalent wireless transmission methods for signal transmission.

The control module 50 is electrically or communicatively connected to the detection module 10 and the lifting device 20 of the vehicle body 10 . For example, in this embodiment, the control module 50 is a microcontroller (Microcontroller Unit, MCU), which has a receiving unit 52 and a processing unit 54 , and the receiving unit 52 is electrically connected to the processing unit 54 . Wherein, the receiving unit 52 is used for receiving the moving signal or the stop signal transmitted by the transmitting units 36, and in this embodiment, the receiving unit 52 cooperates with the two transmitting units 36 to form a wireless transmitting device. The processing unit 54 is electrically connected to the lifting device 20, and is used to analyze whether the stop signal or the moving signal is received, so as to judge whether the vehicle body 10 is in a stopped state or a moving state, so as to control the lifting device 20 to make the Seat cushion 18 rises or falls.

The present invention, which is formed by combining the structures of the above-mentioned components, is to provide an automatic lifting system for a seat cushion of a bicycle. Its actual operation and application are as follows: When the user rides the car body 10, the speed sensing unit 32 and the pressure sensing unit 34 of the detection module 30 will detect whether it is in a stopped state or a moving state and generate an immediate stop signal or the After the mobile signal is transmitted to the receiving unit 52 of the control module 50 through the two transmission units 36, the The processing unit 54 performs the analysis. When the processing unit 54 analyzes that it is the stop signal, it means that the car body is in the parking state at this time, and then controls the lifting device 20 to lower the seat cushion 18; when the processing unit 54 analyzes it as the moving signal, it means that This moment, this car body is in moving state, controls this elevating device 20 to raise this seat cushion 18 immediately.

Figures 3 and 4 show that when the user enters the parking state from the moving state, the rotational speed of the two wheels 14 begins to approach or equal to 0 rpm, and the user's feet usually leave the two pedals 16 to step on the ground to maintain balance . At this time, the stop signal generated by the detection module 30 is transmitted to the control module 50, so that the processing unit 54 of the control module 50 analyzes that it is the stop signal, which means that the vehicle body 10 is currently in the parked state. Therefore, the lifting device 20 is controlled to descend, and then the seat cushion 18 is lowered so that the user can easily step on the ground.

On the contrary, Fig. 3 and Fig. 5 show that when the user enters the moving state from the parking state, the rotation speed of the two wheels 14 starts to increase, and the user's feet step on the two pedals 16 respectively to apply force. At this time, the movement signal generated by the detection module 30 is transmitted to the control module 50, so that after the processing unit 54 of the control module 50 analyzes the movement signal, it means that the vehicle body 10 is currently in the mobile state. Therefore, the lifting device 20 is controlled to rise, and then the seat cushion 18 is raised so that the user can ride in a more labor-saving posture.

It should be added that the detection module 30 of the present invention is not limited to the use of the rotational speed sensing unit 32 and the pressure sensing unit 34 at the same time, the rotational speed sensing unit 32 or the pressure sensing unit 34 can be configured separately, A brake sensing unit for sensing the degree of braking, a cadence sensing unit for sensing the pedaling frequency, or other sensing units that can sense whether the vehicle body 10 is in a stopped state or in a moving state can also be separately configured, or The aforementioned sensing units are used in any combination to generate a more accurate stop signal or the movement signal.

In summary, the seat cushion automatic lifting system provided by the present invention uses the sensing units 32, 34 of the detection module 30 to detect whether the vehicle body 10 is in a stopped state or a moving state ( Such as the wheel speed, whether the pedal is stepped on, etc.), and a stop signal or a movement signal is generated and transmitted to the control module 50 accordingly. After the control module 50 receives and analyzes the signal as the stop signal or the movement signal, it controls the lifting device 20 to descend or ascend. According to the above technical features, when the user parks, the seat cushion 18 will automatically descend, so that the user's feet can step on the ground, reducing the need for the user to weigh his feet or tilt when parking, which will cause dangerous situations; The seat cushion 18 will automatically rise when the user starts to ride a bicycle, so that the user can ride at a higher seat cushion height, which is less labor-saving and less likely to be injured when riding with a lower seat cushion. The present invention provides an automatic and humanized bicycle seat cushion automatic lifting system, which not only improves the user's riding experience, but also improves the safety during riding.
