Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to a bicycle and a solar power supply system thereof. Background Art

[0002] Solar panels (also known as solar cell arrays) can directly convert sunlight into electricity, making them widely used as a low-carbon, clean energy source. In the bicycle industry, solar panels made of crystalline silicon are becoming a core component for obtaining energy from vehicle batteries and are widely used in the bicycle industry.

[0003] While crystalline silicon solar panels offer high photoelectric conversion efficiency, they require relatively high light intensity and can only generate electricity in strong sunlight. Therefore, crystalline silicon solar panels are also known as high-light solar panels. When a bicycle is exposed to low light for extended periods, the panels' power generation efficiency is low, and the vehicle's battery charge may continue to decline due to a lack of effective recharging, ultimately leading to a low battery.

[0026] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] As used herein, the term "including" and its variations represent open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based at least in part on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment."

[0028] As described above, strong light solar panels are widely used in bicycles to recharge the vehicle batteries of bicycles, and the vehicle batteries are used to supply power to multiple power modules of electric vehicles. The bicycle can be a (shared) bicycle, a (shared) electric motorcycle, a motorcycle, etc. When the bicycle is in low light conditions for a long time, the strong light solar panels do not work, and the power of the vehicle battery may continue to decline due to long-term lack of effective power replenishment, eventually leading to low power. The embodiments of the present disclosure provide a bicycle and a solar power supply system thereof to solve the problem in the prior art that the solar power supply system of a bicycle cannot recharge the vehicle battery under low light conditions. In the following, it will be combined with Figures 1 to 6 The principles of the present disclosure are described.

[0029] Figure 1 FIG. 1 shows a structural block diagram of a solar power supply system 100 for a bicycle according to an embodiment of the present disclosure. Figure 2 A structural block diagram of a solar power supply system for a bicycle according to another embodiment of the present disclosure is shown. Figures 3 to 6 Different arrangements of strong-light solar panels and weak-light solar panels of a solar power supply system for a bicycle according to an embodiment of the present disclosure are shown.

[0030] See also Figure 1 and Figure 2The solar power supply system 100 for a bicycle includes a high-intensity solar panel 10, a low-intensity solar panel 20, and a switch control module 30. The high-intensity solar panel 10 is electrically connected to the vehicle battery 60 via a first circuit 11, which is provided with a first switch 12. The low-intensity solar panel 20 is electrically connected to the vehicle battery 60 via a second circuit 21, which is connected in parallel with the first circuit 11. The switch control module 30 is electrically connected to the first switch 12 and is configured to control the first switch 12 to be disconnected when the first voltage output by the high-intensity solar panel 10 is lower than a first threshold, and to control the first switch 12 to be connected when the first voltage is equal to or higher than the first threshold.

[0031] The high-light solar panel 10 and the low-light solar panel 20 are relative. In some embodiments, the high-light solar panel 10 and the low-light solar panel 20 can be configured such that, for example, the high-light solar panel 10 generates a first voltage (electrical energy) when the incident light intensity is greater than or equal to a preset light intensity threshold, and the low-light solar panel 20 generates a second voltage (electrical energy) when the incident light intensity is greater than or equal to the preset light intensity threshold, with the first voltage being greater than or equal to the second voltage. Furthermore, the high-light solar panel 10 generates a third voltage (electrical energy) when the incident light intensity is less than the preset light intensity threshold, and the low-light solar panel 20 generates a fourth voltage (electrical energy) when the incident light intensity is less than the preset light intensity threshold, with the third voltage being less than the fourth voltage.

[0032] The high-intensity solar panel 10 can be made, for example, of crystalline silicon, including but not limited to monocrystalline silicon and polycrystalline silicon. The high-intensity solar panel 10 has a high photoelectric conversion efficiency under strong light conditions, but its photoelectric conversion efficiency rapidly decreases under weak light conditions (such as, but not limited to, rainy days). Therefore, it is not suitable for charging the vehicle battery 60 in weak light conditions. High-intensity solar panels 10 made of crystalline silicon generally have a certain degree of rigidity and are therefore also referred to as rigid solar panels or rigid solar cells.

[0033] The low-light solar panel 20 can be made, for example, of amorphous silicon, including but not limited to cadmium telluride (CdTe) and copper indium gallium selenide (CIGS). Compared to the high-light solar panel 10, the low-light solar panel 20 exhibits lower photoelectric conversion efficiency under brighter light conditions, but experiences less of a drop in efficiency under weaker light conditions. Therefore, it is suitable for charging the vehicle battery 60 in weaker light conditions. The low-light solar panel 20, made of amorphous silicon, is flexible and can therefore also be referred to as a flexible solar panel or flexible solar cell.

[0034] The bicycle solar power supply system 100 provided in the embodiments of the present disclosure utilizes a combination of a high-light solar panel 10 and a low-light solar panel 20. This ensures that in high-light environments, the high-light solar panel 10 primarily replenishes power to the vehicle battery 60, while in low-light environments, the low-light solar panel 10 primarily replenishes power to the vehicle battery 60. This allows the bicycle to be effectively charged even when exposed to low light conditions (e.g., during the rainy season or other rainy weather), preventing the battery from running low due to prolonged exposure to low light.

[0035] More specifically, see Figure 1 and Figure 2 The high-light solar panel 10 supplies power to the vehicle battery 60 via the first circuit 11, while the low-light solar panel 20 supplies power to the vehicle battery 60 via the second circuit 21. The first circuit 11 and the second circuit 21 are connected in parallel. When the bicycle is in a high-light environment, the first voltage is equal to or higher than the first threshold value, indicating that the high-light solar panel 10 has a high photoelectric conversion efficiency and is suitable for charging the vehicle battery 60. The switch control module 30 then controls the first switch 12 to conduct, allowing the high-light solar panel 10 to supply power to the vehicle battery 60. At this time, the second circuit 21 can be in an open or closed state as needed. In a high-light environment, when the second circuit 21 is in the open state, the low-light solar panel 20 can supply power to the vehicle battery 60. That is, in a high-light environment, the high-light solar panel 10 and the low-light solar panel 20 can simultaneously supply power to the vehicle battery 60, allowing the vehicle battery 60 to be quickly and fully replenished.

[0036] When the bicycle is in low-light conditions, the first voltage of the high-light solar panel 10 falls below the first threshold. This indicates that the photovoltaic conversion efficiency of the high-light solar panel 10 is low, insufficient to charge the vehicle battery 60, and may even act as a power consumer, consuming the energy generated by the low-light solar panel 20. In this situation, the switch control module 30 controls the first switch 12 to open, and the high-light solar panel 10 no longer supplies power to the vehicle battery 60. In low-light conditions, the second circuit 21 remains open, and the low-light solar panel 20 alone supplies power to the vehicle battery 60.

[0037] The vehicle battery 60 may be, but is not limited to, a lithium battery. In some embodiments, the voltage of the vehicle battery 60 ranges from 3.0V to 4.2V, more specifically, from 3.6V to 4.2V. In some embodiments, the vehicle battery 60 may output a relatively high current to multiple power-consuming modules 70. The output current may be, for example, but not limited to, 2000mA. In some embodiments, the multiple power-consuming modules 70 are connected to the output terminal 62 of the vehicle battery 60 via, for example, multiple parallel circuits 71. Each parallel circuit 71 may be provided with a switch 72 for controlling the on / off of the corresponding parallel circuit 71.

[0038] Continue to see Figure 1 and Figure 2 In some embodiments, the bicycle solar power supply system 100 may further include a voltage converter 40, which may be, for example, but not limited to, a DC-DC boost converter. The first circuit 11 and the second circuit 21 are connected in parallel to the input terminal 401 of the voltage converter 40. The first output terminal 402 of the voltage converter 40 is electrically connected to the input terminal 61 of the vehicle battery 60 via the third circuit 43. When the voltage supplied to the input terminal 401 of the voltage converter 40 by the high-intensity solar panel 10 via the first circuit 11 and / or the low-intensity solar panel 20 via the second circuit 21 is insufficient, for example, when the voltage supplied to the input terminal 401 of the voltage converter 40 is less than or equal to the target voltage of the vehicle battery 60, the voltage converter 40 may boost the voltage, thereby charging the vehicle battery 60 and increasing its charge. In some embodiments, the current output from the first output terminal 402 of the voltage converter 40 to the vehicle battery 60 is, for example, less than 1000 mA.

[0039] It should be noted that although Figure 1 and Figure 2 In the embodiment, the first circuit 11 and the second circuit 21 are electrically connected in parallel to two input terminals 401 at different positions of the voltage converter 40. In practical applications, the parallel first circuit 11 and the second circuit 21 can be electrically connected to the same input terminal 401 of the voltage converter 40 through a line. That is, the same input terminal 401 of the voltage converter 40 is connected to the parallel output terminals of the first circuit 11 and the second circuit 21.

[0040] Continue to see Figure 1 and Figure 2 In some embodiments, the solar power supply system 100 of the bicycle may further include a second switch 22. The second switch 22 is provided in the second circuit 21 and is electrically connected to the switch control module 30. The switch control module 30 is used to control the disconnection and conduction of the second switch 22 so that the second circuit 21 is switched to an open circuit state or a closed circuit state. The second switch 22 can be turned on or off as needed. As described above, in a strong light environment and when the second switch 22 is turned on, the weak light solar panel 20 can cooperate with the strong light solar panel 10 to replenish power to the vehicle battery 60. In a strong light environment and when the second switch 22 is disconnected, the strong light solar panel 20 replenishes power to the vehicle battery 60 alone. In a weak light environment, the second switch 22 remains turned on, so that the weak light solar panel 20 can replenish power to the vehicle battery 60 alone.

[0041] Figure 1An exemplary embodiment of the switch control module 30 is shown in FIG. Specifically, the switching control module 30 includes a controller 31. The controller 31 is electrically connected to the high-intensity solar panel 10 via a first detection circuit 311 to obtain a first voltage output by the high-intensity solar panel 10. The controller 31 then controls the first switch 12 to open or close based on a comparison between the first voltage and a first threshold.

[0042] Continue to see Figure 1 In some embodiments, the controller 31 can be electrically connected to the weak-light solar panel 20 through the second detection circuit 312 to obtain the second voltage output by the weak-light solar panel 10. In some embodiments, the controller 31 controls the on and off of the second switch 22 as needed.

[0043] Continue to see Figure 1 In some embodiments, the second output terminal 403 of the voltage converter 40 is connected to the controller 31 through the power supply circuit 44 to supply power to the controller 31. The current of the power supply circuit 44 can be, for example, but not limited to, 100 mA.

[0044] Continue to see Figure 1 In some embodiments, the power supply circuit 44 is provided with a third switch 45, which is used to detect the operating status of the controller 31. If the controller 31 crashes, the third switch 45 can be disconnected, disconnecting the power supply circuit 44 and allowing the controller 31 to restart. The third switch 45 can be, but is not limited to, a watchdog switch. By providing the third switch 45, the stable operation of the solar power supply system 100 can be prevented from being affected by a crash of the controller 31.

[0045] In some embodiments, the vehicle battery 60 can supply power to the controller 31 via the third circuit 43, the voltage converter 40, and the power supply circuit 44. For example, when the bicycle is in a dark environment for a long time and the high-light solar panel 10 and the low-light solar panel 20 basically do not output voltage, the vehicle battery 60 can supply power to the controller 31.

[0046] Continue to see Figure 1 In some embodiments, the first switch 12 may include a first metal oxide semiconductor field effect transistor (also referred to as a first MOS switch), and the second switch 22 may include a second metal oxide semiconductor field effect transistor (also referred to as a second MOS switch). The first switch 12 and the second switch 22 may be collectively referred to as MOS switches. Of course, in some alternative embodiments, the types of the first switch 12 and the second switch 22 are not limited to MOS switches.

[0047] Continue to see Figure 1In some embodiments, the first switch 12 , the second switch 22 , the voltage converter 40 , the vehicle battery 60 , the third switch 45 , the controller 31 , the power module 70 , etc. may be integrated on a printed circuit board 80 .

[0048] In addition, the wiring harness of the first circuit 11 and the first detection circuit 311 located between the high-intensity solar panel 10 and the printed circuit board 80 can be integrated into the wiring harness 15. The wiring harness of the second circuit 21 and the second detection circuit 312 located between the high-intensity solar panel 10 and the printed circuit board 80 can be integrated into the wiring harness 25.

[0049] Figure 2 , another exemplary embodiment of the switch control module 30 is shown in FIG. The switch control module 30 uses the output voltage of the high-intensity solar panel 10 and the output voltage of the low-intensity solar panel 20 as direct control sources to control the on / off of the first switch 12 and the second switch 22 based on hardware.

[0050] See also Figure 2 Specifically, the first switch 12 includes a first input terminal 121, a first output terminal 122, and a first voltage collection terminal 123. The first circuit 11 includes a first input circuit 111 and a first output circuit 112. The rigid solar panel 10 is electrically connected to the first input terminal 121 of the first switch 12 via the first input circuit 111. The first output terminal 122 of the first switch 12 is electrically connected to the voltage converter 40 / vehicle battery 60 via the first output circuit 112.

[0051] The second switch 22 includes a second input terminal 221, a second output terminal 222, and a second voltage collection terminal 223. The second circuit 21 includes a second input circuit 211 and a second output circuit 212. The low-light solar panel 20 is electrically connected to the second input terminal 221 of the second switch 22 via the second input circuit 211. The second output terminal 222 of the second switch 22 is electrically connected to the voltage converter 40 / vehicle battery 60 via the second output circuit 212.

[0052] The switch control module 30 includes a first control circuit 321 and a second control circuit 322. The first control circuit 321 is connected between the first voltage acquisition terminal 123 and the vehicle battery 60, and the second control circuit 322 is connected between the first output terminal 122 and the second voltage acquisition terminal 223. In some embodiments, the second control circuit 322 is grounded via a ground circuit 325, which is connected in series with a resistor 324.

[0053] In a low-light environment, based on a first comparison result between the sum of the voltage at the first voltage collection terminal 123 and the second threshold and the voltage at the first input terminal 121 , the first switch 12 is disconnected and the second switch 22 is turned on, and only the low-light solar panel 20 supplies power to the vehicle battery 60 .

[0054] In a strong light environment, based on a second comparison result of the sum of the voltage at the first voltage collection terminal 123 and the second threshold with the voltage at the first input terminal 121 , the first switch 12 is turned on and the second switch 22 is turned off, and only the strong light solar panel 10 replenishes power to the vehicle battery 60 .

[0055] In some embodiments, the first switch 12 may include a first PMOS switching transistor, and the second switch 22 may include a second PMOS switching transistor. That is, the first switch 12 and the second switch 22 may be collectively referred to as PMOS switches. Specifically, the first input terminal 121 of the first switch 12 may be referred to as the S-pole or source, the first output terminal 122 may be referred to as the D-pole or drain, and the first voltage collection terminal 123 may be referred to as the G-pole or gate. Correspondingly, the second input terminal 221 of the second switch 22 may be referred to as the S-pole or source, the second output terminal 222 may be referred to as the D-pole or drain, and the second voltage collection terminal 223 may be referred to as the G-pole or gate. Of course, in alternative embodiments, the first switch 12 and the second switch 22 may be other types of switches, not limited to PMOS switches.

[0056] When the first switch 12 and the second switch 22 are PMOS switches, the principle of the switch control module 30 controlling the on and off of the first switch 12 and the second switch 22 is as follows.

[0057] In low-light conditions, the photoelectric conversion efficiency of the high-light solar panel 10 is low, and the voltage at the first input terminal 121 is lower than the sum of the voltage at the first voltage collection terminal 123 (i.e., the battery voltage) and the second threshold (i.e., the first comparison result). The first switch 12 is disconnected, and the first circuit 11 is in an open state. The second threshold can be, for example, but not limited to, 0.7V. At this time, the voltage at the second voltage collection terminal 223 of the second switch 22 is zero, and the voltage at the second input terminal 221 is equal to or higher than the sum of the voltage at the second voltage collection terminal 223 and the third threshold. The second switch 22 is turned on, and the second circuit 21 is in an open state. At this time, the low-light solar panel 20 supplies power to the vehicle battery 60, while the high-light solar panel 10 does not. In some embodiments, the third threshold can be, but is not limited to, the same as the second threshold.

[0058] In bright sunlight, the high-intensity solar panel 10 achieves high photoelectric conversion efficiency. The voltage at the first input terminal 121 is equal to or greater than the sum of the voltage at the first voltage collection terminal 123 (i.e., the battery voltage) and the second threshold (i.e., the second comparison result). The first switch 12 turns on, and the first circuit 11 is in a conductive state. At this point, the second voltage collection terminal 223 of the second switch 22 transitions from a low level to a high level. The voltage at the second input terminal 221 falls below the sum of the voltage at the second voltage collection terminal 223 and the third threshold. The second switch 22 turns off, and the second circuit 21 is in an open state. At this point, the high-intensity solar panel 10 supplies power to the vehicle battery 60, while the low-intensity solar panel 20 does not.

[0059] In some embodiments, the first output circuit 112 may be provided with a first one-way switch 113, and / or the second control circuit 322 may be provided with a second one-way switch 323. The first one-way switch 113 and the second one-way switch 323 may be diodes. By providing the first one-way switch 113 and / or the second one-way switch 323, discharge of the vehicle battery 60 to the high-light solar panel 10 and the low-light solar panel 20 can be effectively prevented.

[0060] Figure 3 An exemplary arrangement of the high-light solar panel 10 and the low-light solar panel 20 is shown. Specifically, the high-light solar panel 10 and the low-light solar panel 20 are mounted on the same sheet 50. The sheet 50 not only serves to locate the positions of the high-light solar panel 10 and the low-light solar panel 20, but also integrates the high-light solar panel 10 and the low-light solar panel 20 together, so that they can be installed as a whole in a suitable position of the bicycle, for example, they can be installed in the bicycle basket. In some embodiments, the sheet 50 can be laid on the bottom wall of the basket. The high-light solar panel 10 and the low-light solar panel 20 can be simultaneously provided on the same surface 53 of the sheet 50. When the sheet 50 is placed flat in the basket, the surface 53 can be the top surface of the sheet 50. In some embodiments, the low-light solar panel 20 can be arranged around at least a portion of the high-light solar panel 10.

[0061] Figure 4 Another exemplary arrangement of high-light solar panels 10 and low-light solar panels 20 is shown. Low-light solar panels 20 can be centrally located on surface 53, while high-light solar panels 10 can be arranged around the perimeter of low-light solar panels 20. The area where low-light solar panels 20 are located is easily obscured by debris that enters the vehicle basket, so this arrangement minimizes the impact of debris on high-light solar panels 10.

[0062] More specifically, if Figure 4As shown, the high-intensity solar panel 10 may include a pair of high-intensity solar panel units spaced apart from each other, with the low-intensity solar panel 20 positioned between the pair of high-intensity solar panel units. In other words, the low-intensity solar panel 20 is positioned in the middle of the basket, where it is easily obscured by debris, to minimize the impact of debris on the high-intensity solar panel 10.

[0063] Figure 5 1 and 2. Another exemplary arrangement of the strong light solar panels 10 and the weak light solar panels 20 is shown. The strong light solar panels 10 and the weak light solar panels 20 on the surface 53 are arranged left and right.

[0064] Figure 6 1 and 2. Another exemplary arrangement of the strong light solar panels 10 and the weak light solar panels 20 is shown. When the sheet 50 is placed flat in the basket, the strong light solar panels 10 and the weak light solar panels 20 on the surface 53 are arranged front to back.

[0065] In some embodiments not shown, the high-intensity solar panel 10 can be mounted on a first surface of the sheet 50, and the low-intensity solar panel 20 can be mounted on a second surface of the sheet 50. When the sheet 50 is placed flat in the basket, the first surface is, for example, the top surface of the sheet 50, and the second surface is, for example, the bottom surface of the sheet 50.

[0066] Of course, the arrangement of the high-light solar panels 10 and low-light solar panels 20 is not limited to the above examples and can be combined as needed. Due to the flexible nature of the low-light solar panels 20, made of amorphous silicon, they can be placed in any suitable location on the basket and the bicycle body. For example, the low-light solar panels 20 can be placed on the side walls of the basket, while the high-light solar panels 10 can be placed on the bottom wall of the basket. Alternatively, the high-light solar panels 10 can be placed on the bottom wall of the basket and on the sides of the basket that are easily exposed to light, while the low-light solar panels 20 can be placed on the rear side of the basket or any other suitable area on the bicycle body that is easily installed and has a large light-receiving area.

[0067] The embodiments of the present disclosure further provide a bicycle, which is equipped with the solar power supply system of any of the above embodiments.

[0068] In the embodiment of the present disclosure, a combination of a high-light solar panel 10 and a low-light solar panel 20 is employed to achieve the goal of primarily replenishing the vehicle battery 60 with power from the high-light solar panel 10 in high-light environments, and primarily replenishing the vehicle battery 60 with power from the low-light solar panel 10 in low-light environments. This allows the vehicle battery 60 to be effectively replenished even when the bicycle is exposed to low light conditions for extended periods (e.g., during the rainy season or other rainy weather), preventing the battery from running low due to prolonged exposure to low light.

[0069] While various embodiments of the present disclosure have been described above, the above descriptions are illustrative, non-exhaustive, and not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
