Description

Technical Field

[0001] The present invention relates to the technical field of cycling equipment, and particularly to a self-powered cycling stand with a safe constant current output. Background Art

[0002] More and more people have started to participate in bicycle riding sports. However, outdoor riding is restricted by road conditions and weather factors and cannot fully meet the needs of riders. A cycling stand provides resistance to the rear wheel of a bicycle to simulate outdoor riding.

[0003] Existing cycling stands can generate electricity by themselves. During the riding process, the motor can generate electricity, but the electricity generated by general self-powered cycling stands is dissipated in the form of heat through a resistor. In addition, users need to connect electronic devices such as mobile phones, computers, and tablets during the riding process, but in many cases, they also face the situation that the electronic devices run out of power. Since the self-powered cycling stand itself does not need to be plugged in and there is no mains power around, it is difficult to charge the electronic devices.

[0004] In summary, there is a need to design a self-powered cycling stand with a safe constant current output to solve the above problems in the prior art. Summary of the Invention

[0005] To solve the above problems in the prior art, the present invention provides a self-powered cycling stand with a safe constant current output, which avoids the problem of energy waste of self-generated electricity.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A self-powered cycling stand with a safe constant current output, comprising: A motor, the rotor shaft of which is used to be connected to the transmission device shaft of the cycling stand; A power supply module, which includes an isolation unit and an external connection unit; wherein the isolation unit receives the output voltage of the motor through a control module; the external connection unit is used to provide a charging output port; A control module, which is connected to the motor, and the control module is used to receive the output voltage signal of the motor; the control module is also used to be electrically connected to the isolation unit through a function switch; Wherein, the control module is used to control the function switch according to the working state of the motor; when the cycling stand is in a static state, the control module is used to control the function switch to be disconnected.

[0009] In some embodiments of the present invention, the control module is used to set an initial startup power. When the real-time riding power is greater than the initial startup power, the module controls the function switch to close; the control module is used to set a full-load startup power. When the real-time riding power is greater than the full-load startup power, the control module adjusts the output power of the charging output port to the rated power.

[0010] In some embodiments of the present invention, the control module is used to set a fusing riding power. When the real-time riding power is less than the fusing riding power, the control module controls the function switch to open.

[0011] In some embodiments of the present invention, the control module is further used to detect the remaining power of the charging device end and to control the power of the output voltage of the power module according to the remaining power.

[0012] In some embodiments of the present invention, when the remaining power is lower than 90% of the total power, the control module raises the output power of the charging output port to the rated power; when the remaining power is not lower than 90% of the total power, the control module reduces the power of the output voltage of the power module to the trickle mode power.

[0013] In some embodiments of the present invention, a first riding power is built into the control module. When the real-time riding power is greater than the set first riding power, the control module controls multiple charging output ports to charge the device to be charged according to the charging protocol requirements; the multiple charging output ports include a wired charging port and a wireless charging port.

[0014] In some embodiments of the present invention, when the real-time riding power is less than the first riding power, the charging priority of the wired charging port is higher than that of the wireless charging port.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0024] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0025] Referring to Figures 1 - 3 as shown, a self - generating exercise bike with a safe constant - current output includes: a motor, the rotor shaft of which is used to connect with the transmission device shaft of the exercise bike; a power supply module 100, which includes an isolation unit 110 and an external connection unit 120; wherein the isolation unit 110 receives the output voltage of the motor through a control module 200; the external connection unit 120 is used to provide a charging output port; a control module 200, which is connected to the motor, and the control module 200 is used to receive the output voltage signal of the motor; the control module 200 is also used to be electrically connected to the isolation unit 110 through a function switch 300; wherein, the control module 200 is used to control the function switch 300 according to the working state of the motor; when the exercise bike is in a static state, the control module 200 is used to control the function switch 300 to be disconnected.

[0026] During the user's cycling process, the motor rotates driven by the transmission device shaft of the exercise bike, and converts the energy output by the rider stepping on the exercise bike into electric energy; the power supply module 100 can rectify the electric energy output by the motor and form a stable voltage to be input into the mobile terminal for charging.

[0027] The control module 200 is used to adjust or control the output voltage of the power supply module 100 according to the cycling power.

[0028] Continuing to refer to Figure 1 as shown, the main control board in the figure is the circuit board for realizing the function of the control module 200; the power supply board is the circuit board for realizing the function of the power supply module 100.

[0029] The main control board is used to control the power supply board to output a variable bus voltage of 25 - 100V. The selection of the bus voltage is based on the change of cycling power.

[0030] In order to meet low power consumption, a function switch 300 is provided, and the function switch 300 is used to control the on - off connection relationship between the control module 200 and the power supply module 100; when the cycling power is low, the control module 200 recognizes that the current is a static environment and cannot charge externally, and the control module 200 uses the function switch 300 to cut off its connection with the power supply module 100.

[0031] In some embodiments of the present invention, when the exercise bike is in a stationary state, the control module 200 adjusts the function switch 300 to an off state, that is, the control module 200 actively cuts off the connection with the isolation unit 110 of the power supply module 100 and does not charge externally to prevent continuous power loss.

[0032] In some embodiments of the present invention, the control module 200 further includes a current detection unit 210, and the current detection unit 210 is used to monitor the output power of the external unit 120; the output power is used to calculate the charging power.

[0033] Specifically, for an exercise bike that uses a main control board to implement the functions of the control module 200, the current detection unit 210 is arranged at the GND port of the main control board; the current detection unit 210 is used to monitor the output power of the external unit 120, detect the external output power (i.e., the charging power) by integration, and at the same time, the power generation utilization rate can be analyzed.

[0034] In some embodiments of the present invention, the exercise bike further includes a riding power detection module, which is used to collect the real-time riding power of the exercise bike; the control module 200 is used to control the output voltage power of the power supply module 100 according to the real-time riding power.

[0035] Specifically, during the user's riding process, due to different riding powers, the control module 200 can adjust the charging power according to the change in riding power.

[0036] In some embodiments of the present invention, in order to improve the charging efficiency, the control module 200 is used to set an initial starting power. When the real-time riding power is greater than the initial starting power, the module controls the function switch 300 to close; specifically, when the real-time riding power is greater than 50W, the control module 200 can control the function switch 300 to close, that is, the power supply module 100 outputs voltage.

[0037] In some embodiments of the present invention, the control module 200 is used to set a full-load starting power. When the real-time riding power is greater than the full-load starting power, the control module 200 adjusts the output power of the charging output port to the rated power; specifically, when the real-time riding power is greater than 120W, the control module 200 adjusts the output power of the charging output port to the rated power.

[0038] That is to say, when the real-time riding power is greater than 120W, that is, when the real-time riding power can be maintained in a relatively high range, the self-powered exercise bike can output and charge at full power, and the external unit 120 can support a device to be charged with 36W.

[0039] In some embodiments of the present invention, a fusing cycling power is set in the control module 200, and the fusing cycling power is slightly lower than the initial starting power. Specifically, during the process of cycling and charging, even when the cycling power drops to the initial starting power, for example, 50W, the state of the function switch 300 remains closed, that is, the power supply module 100 continues to supply power externally. When the real-time cycling power continuously drops to the fusing cycling power, for example, 45W, the control module 200 controls the function switch 300 to disconnect, and the power supply module 100 ends the external power supply.

[0040] Specifically, the fusing cycling power is set to 45W. When the real-time cycling power is less than 45W, the control module 200 controls the function switch 300 to disconnect.

[0041] That is to say, during the charging process, when the cycling power is lower than 45W, after the control module 200 adjusts the function switch 300 to disconnect, the power supply module 100 stops charging externally.

[0042] In some embodiments of the present invention, the control module 200 is further configured to detect the remaining power of the charging device end, and is configured to control the output voltage power of the power supply module 100 according to the remaining power.

[0043] In some embodiments of the present invention, when the remaining power is lower than 90% of the total power, the control module 200 raises the output power of the charging output port to the rated power; when the remaining power is not lower than 90% of the total power, the control module 200 reduces the output voltage power of the power supply module 100 to the trickle mode power.

[0044] Specifically, when the remaining power of the charging device is lower than 90% of the total power, the control module 200 adjusts the output voltage power of its corresponding charging port to the rated power, that is, charges with the maximum power. When the remaining power of the charging device is not lower than 90% of the total power, the control module 200 adjusts the output voltage power of its corresponding charging port to decrease and charges with the trickle mode power.

[0045] In some embodiments, the charging power in the trickle mode is not higher than 60W.

[0046] In some embodiments of the present invention, the self-powered cycling stand can support multiple devices to charge simultaneously. Specifically, a first cycling power is built into the control module 200. When the real-time cycling power is greater than the set first cycling power, the control module 200 can control multiple charging output ports to charge the devices to be charged according to the charging protocol requirements, and the control module 200 enables the charging functions of multiple charging output ports.

[0047] In some embodiments, the first riding power can be set to 100W. That is, when the real-time riding power is greater than 100W, the control module 200 can control multiple charging output ports to charge the device to be charged according to the charging protocol requirements.

[0048] In addition, multiple charging output ports include a wired charging port and a wireless charging port. That is to say, when the real-time riding power is greater than the first riding power, both the wired charging port and the wireless charging port can output voltage to achieve charging.

[0049] In some embodiments of the present invention, when the real-time riding power is less than the first riding power, and the control module 200 detects that both the wired charging port and the wireless charging port are turned on, the control module 200 adjusts the wireless charging port to be turned off, and only the wired charging port is retained because the power of the wired charging port is large and the charging is faster.

[0050] In addition, when the external wired device is disconnected, it automatically switches to the wireless device for charging.

[0051] Specifically, in this embodiment, the first riding power can also be selected as 100W. That is, when the real-time riding power is less than 100W, the charging priority of the wired charging port is higher than that of the wireless charging port.

[0052] In some embodiments of the present invention, continue to refer to Figure 1 As shown, the isolation unit 110 includes a transformer isolation and an IC controller. The isolation unit 110 further includes a protocol chip, and the protocol chip is connected to the external unit 120.

[0053] In some embodiments of the present invention, continue to refer to Figure 2 As shown, the control module 200 can detect the real-time power of riding, and then control the state of the function switch 300 according to the real-time power. The bus output voltage range corresponding to the function switch 300 is 25 - 100V. In addition, during the charging process, the control module 200 can detect the charging current, calculate the charging power through the charging current, and obtain the charging power after integrating the data.

[0054] Specifically, referring to Figure 1 As shown, relevant circuits for current detection are set on the GND of the control module 200 to monitor the output power of the power module 100, detect the external output power, that is, the charging power, in an integrated manner, and upload the charging power to the monitoring device, which is convenient for users to view the charging energy during the riding process and can also analyze the power generation utilization rate.

[0055] In some embodiments of the present invention, refer toFigure 3 As shown, for the power supply module 100, when the direct current output by the motor of the self-generating exercise bike enters the power supply module 100, the power supply module 100 first rectifies it. After passing through a converter, specifically, after transformer isolation and a switch IC controller, a stable secondary output is obtained and then, through a protocol chip, to USB, enabling wireless output.

[0056] Specifically, the secondary rectified output realizes a stable secondary output through an SR controller. At the same time Figure 3 the converter in [description] can adjust the IC controller by using an opening and can supply power to the IC controller.

[0057] In addition, the protocol chip feeds back information to the IC controller.

[0058] In some embodiments of the present invention, the power supply module 100 receives an input voltage of 25 - 100V and can output stable safe voltages of 12V / 9V / 5V, and the input and output are in an isolated state.

[0059] The input of the power supply module 100 is of constant power. Since the voltage fluctuates, the current will increase as the voltage decreases, achieving the effect of stable power. After isolation processing, the power supply module 100 outputs a stable current and a stable voltage, thereby achieving stable power output. At the same time, it supports 9V3A, 9V2A, 9V1A, 5V3A, 5V2A, 5V1A, etc. under different protocols.

[0060] The technical solution of the present invention has the following technical effects compared with the prior art: The exercise bike provided by the present invention can dynamically adjust the output power according to the riding power, achieving a safe constant voltage and constant current output mode, realizing energy recovery, reducing energy waste, and reducing the heat of the whole machine.

[0061] In the description of the above embodiments, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
