[0033] Figure 1 A partial structural schematic diagram of an electric bicycle provided by an embodiment of the present utility model. Refer to Figure 1 , the electric bicycle includes: a shock absorber module 100, an electromagnetic winding assembly 200 is arranged on the shock absorber module 100, and the shock absorber module 100 is used to change the magnetic field of the electromagnetic winding assembly 200 based on the change of the stroke and detect the change of the magnetic field to output the load-bearing data; a vehicle controller 300, electrically connected to the shock absorber module 100, and used to control the power-on or power-off of the whole vehicle according to the load-bearing data.

[0034] Specifically, the shock absorber module 100 can be a shock absorption device installed between the electric bicycle body and the wheel. When the electric bicycle is subjected to a load pressure, the shock absorber module 100 will be squeezed, resulting in a change in its own stroke. An electromagnetic winding assembly 200 is provided on the shock absorber module 100, and the electromagnetic winding assembly 200 can form a magnetic field. The change in the stroke of the shock absorber module 100 will affect the magnetic field strength formed by the electromagnetic winding assembly 200, and the electromagnetic winding assembly 200 outputs the current load data of the electric bicycle corresponding to the change in the magnetic field strength. The vehicle controller 300 can be a device responsible for managing and adjusting the operating state of the electric bicycle. The vehicle controller 300 is connected to the electromagnetic winding assembly 200. Thus, when the load data output by the electromagnetic winding assembly 200 meets the starting driving conditions, the vehicle controller 300 controls the electric bicycle to power on and start, enabling the driver to safely start the electric bicycle; or when the load data does not meet the starting driving conditions, the vehicle controller 300 controls the electric bicycle to be in a power-off state to prevent the electric bicycle from starting and rushing out.

[0035] The technical solution provided by the embodiment of the present invention affects the magnetic field strength of the electromagnetic winding assembly through the change in the stroke of the shock absorber module itself. Thus, when the electric bicycle is subjected to the load pressure from the driver, the electromagnetic winding assembly can output the load data of the electric bicycle in the current state corresponding to the change in the magnetic field strength. Furthermore, when the load data meets the starting driving conditions, the vehicle controller controls the electric bicycle to power on and start, enabling the driver to safely start the electric bicycle. When the load data does not meet the starting driving conditions, the vehicle controller controls the electric bicycle to be in a power-off state to prevent the driving hazard caused by the electric bicycle starting and rushing out. And the load data output by the electromagnetic winding assembly can reflect the weight information of the driver, further improving the convenience, intelligence and driving experience of the electric bicycle.

[0036] Optionally, Figure 2 is a partial structural schematic diagram of a shock absorber module provided by an embodiment of the present invention. On the basis of the above embodiment, refer to Figure 2 . The shock absorber module 100 includes: a hydraulic cylinder 110 and a spring 120; the spring 120 is sleeved on the outer surface of the hydraulic cylinder 110, one end of the spring 120 is connected to one end of the hydraulic cylinder 110, and the other end of the spring 120 is connected to the other end of the hydraulic cylinder 110; the spring 120 deforms based on the change in the stroke of the hydraulic cylinder 110 to change the magnetic field of the electromagnetic winding assembly 200.

[0037] Specifically, the hydraulic cylinder 110 can generate a certain degree of compression when the electric bicycle is under pressure, thereby causing a change in the stroke of the shock absorption module 100. The hydraulic cylinder 110 can be a multi-segment cylindrical structure, and the inner diameter of the spring 120 is larger than the diameter of the widest part of the hydraulic cylinder 110, so that the spring 120 can be sleeved on the outer surface of the hydraulic cylinder 110. The spring 120 can be made of metal. One end of the spring 120 is fixedly connected to the upper end of the hydraulic cylinder 110, and the other end of the spring 120 is fixedly connected to the lower end of the hydraulic cylinder 110. Thus, when the hydraulic cylinder 110 is compressed under pressure, the spring 120 is driven to be compressed, thereby affecting the magnetic field of the electromagnetic winding assembly 200.

[0038] Optionally, based on the above embodiments, continue to refer to Figure 2 . The hydraulic cylinder 110 includes a cylinder block 111 and a piston rod 112; the piston rod 112 is sleeved and connected to the cylinder block 111, and the piston rod 112 reciprocates along the axial direction of the cylinder block 111 to drive a change in the stroke of the hydraulic cylinder 110.

[0039] Specifically, both the cylinder block 111 and the piston rod 112 can be cylindrical structures. A groove is provided in the axial direction of the cylinder block 111, and the piston rod 112 is sleeved and connected to the cylinder block 111 through the groove. When the pressure on the electric bicycle changes, the piston rod 112 can reciprocate along the axial direction of the cylinder block 111 through the groove to drive a change in the stroke of the hydraulic cylinder 110.

[0040] Optionally, based on the above embodiments, continue to refer to Figure 2 . The electromagnetic winding assembly 200 includes: an electromagnetic induction coil 210 and an electromagnetic induction driving unit 220; the electromagnetic induction coil 210 is electrically connected to the electromagnetic induction driving unit 220, and the electromagnetic induction driving unit 220 is used to drive the electromagnetic induction coil 210 to generate a magnetic field and detect the change in the magnetic field to output load-bearing data.

[0041] Specifically, the electromagnetic induction coil 210 can be a cylindrical wire winding. The electromagnetic induction driving unit 220 is electrically connected to both ends of the wire winding. The electromagnetic induction driving unit 220 supplies power to the electromagnetic induction coil 210 to drive the electromagnetic induction coil 210 to generate a magnetic field. When the hydraulic cylinder 110 is compressed and its stroke changes, the spring 120 will be driven to be compressed, and the compressed spring 120 will change the magnetic field intensity generated by the electromagnetic induction coil 210. The electromagnetic induction driving unit 220 can synchronously detect the change amount of the magnetic field intensity, convert it into a digital signal, and calculate the weight of the human body or object borne by the electric bicycle in the current state through algorithm processing, so as to output load-bearing data.

[0042] Optionally, based on the above embodiments, continue to refer to Figure 2。The electromagnetic induction coil 210 is sleeved on one end of the hydraulic cylinder 110 close to the piston rod 112, and the electromagnetic induction coil 210 is arranged between the outer surface of the hydraulic cylinder 110 and the inner surface of the spring 120.

[0043] Specifically, the electromagnetic induction coil 210 can be fixedly sleeved on one end of the hydraulic cylinder 110 close to the piston rod 112, so that the electromagnetic induction coil 210 can reciprocate with the piston rod 112 to increase the sensitivity of the magnetic field change. The electromagnetic induction coil 210 can be sleeved between the outer surface of the piston rod 112 and the inner surface of the spring 120, so that the spring 120 plays a protective role for the electromagnetic induction coil 210 sleeved inside it.

[0044] Optionally, Figure 3 This is a partial structural schematic diagram of a shock absorber module in a compressed state provided by an embodiment of the present invention. On the basis of the above embodiment, continue to refer to Figure 2 and Figure 3 。One end of the hydraulic cylinder 110 close to the piston rod 112 is connected to the electric bicycle body, and one end of the hydraulic cylinder 110 close to the cylinder block 111 is connected to the wheel.

[0045] Specifically, a first fixing component 131 can also be arranged at one end of the shock absorber module 100 close to the piston rod 112, and a second fixing component 132 can also be arranged at one end close to the cylinder block 111. One end of the hydraulic cylinder 110 close to the piston rod 112 can be connected to the electric bicycle body through the first fixing component 131, and the connection between one end of the hydraulic cylinder 110 close to the cylinder block 111 and the wheel can be connected to the wheel through the second fixing component 132. Exemplarily, as Figure 3 shown, when the electric bicycle is under pressure, the piston rod 112 can be compressed downward along the axial direction of the hydraulic cylinder 110 to drive the spring 120 to deform, thereby affecting the magnetic field strength of the electromagnetic induction coil 112, so that the electromagnetic induction driving unit 220 synchronously detects the change amount of the magnetic field strength and then outputs the load-bearing data.

[0046] Optionally, Figure 4 This is a partial structural schematic diagram of another electric bicycle provided by an embodiment of the present invention, Figure 5 This is a flowchart of a vehicle controller controlling the power-on of the whole vehicle provided by an embodiment of the present invention, Figure 6 This is a flowchart of a vehicle controller controlling the power-off of the whole vehicle provided by an embodiment of the present invention. On the basis of the above embodiment, refer to Figure 4 、 Figure 5 and Figure 6. The vehicle controller 300 includes: a vehicle control module 310, which is electrically connected to the electromagnetic induction drive unit 220; the vehicle control module 310 is used to control the vehicle to power on in the first state and control the vehicle to power off in the second state; wherein, the first state is that the load-bearing data is greater than or equal to the first preset weight and the duration is greater than the first preset time; the second state is that the load-bearing data is less than the second preset weight and the duration is greater than the second preset time; the first preset weight is greater than the second preset weight.

[0047] Specifically, preset information can be stored in the vehicle control module 310. The preset information may include: a first preset weight X, a second preset weight Y, a first preset time T1, and a second preset time T2. Among them, the first preset weight X > the second preset weight Y. When the vehicle control module 310 receives the load-bearing data output by the electromagnetic induction drive unit 220, it can control the power-on or power-off state of the electric bicycle according to the relationship between the load-bearing data, the first preset weight X, and the second preset weight Y. Exemplarily, the first state can be that the initial state of the electric bicycle is the power-off state, which is the state where the driver is ready to ride and start the vehicle. The load-bearing data being greater than or equal to the first preset weight X can represent that the driver has got on the vehicle, and the pressure exerted on the electric bicycle meets the weight condition for starting to drive. The duration of the load-bearing data being greater than or equal to the first preset weight X being greater than the first preset time T1 can represent that the driver has finished sitting. At this time, the electric bicycle fully meets the conditions for safe start, and the vehicle control module 310 controls the electric bicycle to power on, and the driver can safely start the electric bicycle. If the conditions for safe start are not met, the electric bicycle continues to maintain the power-off state of the whole vehicle. The second state can be that the initial state of the electric bicycle is the power-on state, which is the state where the driver gets off the vehicle and leaves the vehicle briefly. The load-bearing data being less than the second preset weight Y can represent that the main driver has got off the vehicle, and the pressure exerted on the electric bicycle by other passengers on the vehicle does not meet the weight condition for normal driving, that is, other passengers do not have the ability to drive the vehicle. The duration of the load-bearing data being less than the second preset weight Y being greater than the second preset time T2 can represent that the main driver has left the vehicle. At this time, the electric bicycle does not meet the conditions for safe driving, and the vehicle control module 310 controls the electric bicycle to power off, effectively preventing potential safety hazards caused by the vehicle starting by mistake when the main driver leaves the vehicle while other passengers do not meet the starting driving conditions. It should be noted that when the main driver gets off the vehicle, if the load-bearing data output by the electromagnetic induction drive unit 220 is greater than the second preset weight Y and less than or equal to the first preset weight X, it means that other passengers on the vehicle have the ability to drive the vehicle, and the vehicle control module 310 can keep the vehicle in the power-on state to facilitate other passengers to control the vehicle. If the duration of the load-bearing data being less than the second preset weight Y is less than or equal to the second preset time T2, it can be indicated that the main driver has not left the vehicle, and the vehicle control module 310 can continue to keep the vehicle in the power-on state.

[0048] Optionally, on the basis of the above embodiments, continue to refer to Figure 4 , Figure 5 and Figure 6 . The vehicle controller 300 further includes: a motor control module 320, and the motor control module 320 is connected to the vehicle control module 310; the motor control module 320 is configured to send an unlock command for power-on to the vehicle control module 310 in the first state.

[0049] Specifically, when the first state is satisfied, the vehicle control module 310 sends an unlocking message to the motor control module 320 to unlock the motor control module 320. After the motor control module 320 is unlocked and feedbacks the unlocking message, it sends a power-on unlocking instruction to the vehicle control module 310. The electric bicycle is successfully powered on, the vehicle instrument can display READY, and the electric bicycle can be safely started and ridden. If the motor control module 320 cannot send a power-on unlocking instruction to the vehicle control module 310, or the vehicle control module 310 cannot send an unlocking message to the motor control module 320, the vehicle may have a fault and need to be repaired, and the electric bicycle cannot be started and ridden.

[0050] Optionally, the vehicle control module 310 is a VCU, and the motor control module 320 is an MCU.

[0051] Specifically, the vehicle control module 310 can be a VCU (Vehicle Control Unit) of the electric bicycle. The VCU can be used to collect various input signals, output control instructions, coordinate the work of each control system, and provide monitoring and detection functions to ensure the normal operation of the whole vehicle. The motor control module 320 can be an MCU (Motor control unit) of the electric bicycle. The MCU can control the motor to output a specified torque and speed by receiving the vehicle driving control instructions of the VCU to drive the vehicle to travel.

[0052] Optionally, Figure 7 The present invention provides a flowchart for controlling the power-on and power-off of the whole vehicle. On the basis of the above embodiments, see Figure 7 . The electric bicycle further includes a client 400. The client 400 is communicatively connected to the vehicle control module 310, and the client 400 is used to set a first preset weight X, a second preset weight Y, a first preset time T1, and a second preset time T2.

[0053] Specifically, the client 400 can be a device such as a mobile phone or a tablet. Exemplarily, the client 400 can communicate with the vehicle control module 310 in a Bluetooth connection manner, and correspondingly adjust and set the first preset weight X, the second preset weight Y, the first preset time T1, and the second preset time T2 stored in the vehicle control module 310 according to the weight information of multiple drivers, so as to facilitate the operation of the vehicle by multiple drivers. The client 400 and the vehicle control module 310 can also be in a one-to-one correspondence relationship. After the client 400 and the vehicle control module 310 are successfully matched, the vehicle control module 310 performs power-on and power-off operations according to the load-bearing data applied by the driver to the electric bicycle to prevent other unauthorized persons from driving the vehicle.
