[0001] This invention belongs to the field of motorcycle charging technology, specifically relating to a motorcycle charging control method and a motorcycle. Background Technology

[0002] A motorcycle charging system generally includes the process of the motorcycle charging other electronic devices (such as mobile phones and smartwatches), as well as the process of the motorcycle obtaining external power to charge itself.

[0003] However, it has the following drawbacks: when a motorcycle battery is dead and cannot start, it often requires external jump-starting, which requires the intervention of external professionals, is highly specialized, and carries a certain degree of danger; when charging external electronic devices, it cannot overcome sudden changes in the external environment, such as changes in the charging location or the charging power. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to provide a motorcycle charging control method and motorcycle that improves the safety of jump-starting when the battery is low, simplifies operation, adapts to different external charging scenarios, and improves adaptability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: One aspect proposes a motorcycle charging system, including a battery connected to a charging input line and a wireless charging output line. The key technology lies in the fact that the battery is also connected to a battery activation line. The battery activation circuit is equipped with an activation mobile power supply interface at its end. The wireless charging output line is connected to a wireless charging module at its end. The wireless charging module includes a main charging coil and at least two sets of transient charging coils.

[0006] A further technical solution includes a microprocessor, which is connected to the main charging coil and the transient charging coil via a driving circuit.

[0007] A further technical solution is that the transient charging coil is uniformly arranged around the main charging coil.

[0008] A further technical solution includes a magnetic array; the magnetic array and the wireless charging module are arranged overlappingly.

[0009] A further technical solution is that the transient charging coil and the main charging coil are arranged in an overlapping manner.

[0010] One further technical solution is that all the transient charging coils have the same output power; One further technical solution is that the output power of all the transient charging coils changes linearly, increasing or decreasing.

[0011] A further technical solution is as follows: the microprocessor is connected to an RF module, which is used to acquire the RF signal emitted by the wireless charging device, the RF signal including at least the charging power of the wireless charging device; the microprocessor controls the transient charging coil according to the charging power of the wireless charging device.

[0012] A further technical solution is as follows: the battery activation circuit includes an input protection circuit, a fast charging identification circuit, a DC-DC circuit, and an output protection circuit connected in sequence; the input terminal of the input protection circuit is used as the end of the battery activation circuit, serving as an activation port interface; the output terminal of the output protection circuit is connected to the battery.

[0013] The second aspect proposes a motorcycle charging control method, the key technology of which lies in: a motorcycle charging system including any of the above-mentioned methods, the specific method of which includes: The steps for activating a power bank by activating a depleted battery via a battery activation circuit. Steps for wirelessly charging unknown power electronic devices; Charging control steps used to control movement during the charging process of electronic devices.

[0014] The third aspect proposes a motorcycle, the key technology of which is: the motorcycle is equipped with any of the above-mentioned motorcycle charging systems.

[0015] The beneficial effects of this invention are: The battery activation circuit allows the driver / user to activate the battery when it is low on power by connecting a compatible portable power source through the designated activation port. The activation port is similar to a socket or a regular power cord interface, allowing for jump-starting the motorcycle without any professional skills, simply by following the instructions.

[0016] Wireless charging output lines are used to charge external electronic devices from a battery, such as laptops, tablets, computers, set-top boxes, and mobile devices. They are adaptable to various driving scenarios, such as charging while riding on bumpy roads like mountains or snowy terrain. One design scheme involves evenly surrounding the main charging coil with transient charging coils, setting all transient charging coils and the main charging coil to have the same power output and size. When an electronic device moves onto any of the transient charging coils, the system senses and activates the corresponding coil, shutting down charging at the original coil. This allows for wide-area, full-coverage charging and improves reliability.

[0017] Another approach is to overlap the transient charging coil with the main charging coil, with all transient charging coils being the same size, having the same current direction, and the same winding direction as the main charging coil. The difference lies in the current and the power output. When the main charging coil and the transient charging coil are used together, they can be adapted to charge various power electronic devices, making the output power more closely match that of the electronic devices.

Detailed Implementation

[0019] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention. The methods provided in the embodiments of this application can be executed by a microprocessor, processor, MCU, CPU, etc.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0021] Figure 1 This is a system block diagram of a motorcycle charging system provided in an embodiment of this application. It includes a battery connected to a charging input line and a wireless charging output line. The battery is also connected to a battery activation line. An activation mobile power interface is provided at the end of the battery activation line. A wireless charging module is connected at the end of the wireless charging output line. The wireless charging module includes a main charging coil and two sets of transient charging coils.

[0022] In this embodiment, the charging input line is used to charge the battery, and the wireless charging output line is used to charge external electronic devices from the battery. The electronic devices can be various types of terminals such as laptops, tablets, computers, set-top boxes, and mobile devices (e.g., mobile phones, portable music players, personal digital assistants, dedicated messaging devices, portable gaming devices).

[0023] In this embodiment, the battery activation circuit is used so that when the battery is low on power, the driver / user can connect a compatible portable power source to activate the battery through the set activation portable power source interface. The activation portable power source interface is similar to a socket or a regular power cord interface, which can be used to jump-start the motorcycle without professional skills by following simple instructions.

[0024] In this embodiment, a wireless charging module is connected to the end of the wireless charging output line. This wireless charging module includes a main charging coil and two sets of transient charging coils. The main charging coil is similar to a conventional wireless charging coil and is used to complete wireless charging. The transient charging coils can perform different functions depending on their position. Specifically, this is achieved by combining the following two implementation methods: 1. The transient charging coil is uniformly arranged around the main charging coil. As a further embodiment, the transient charging coil and the main charging coil are arranged on the same horizontal plane for a larger area of ​​full-coverage charging.

[0025] For example, when a motorcycle is traveling on a bumpy road, and the electronic device being charged moves with the charger during the bumpy ride, the solution in this embodiment can still complete the charging process in a comprehensive manner, making it less likely for the device to quickly leave the charging area, thus increasing its reliability.

[0026] 2. The transient charging coil and the main charging coil are arranged overlappingly. In a further embodiment, all transient charging coils and the main charging coil are the same size, have the same current direction, and the same winding direction. The difference lies in the current and power output. When the main charging coil and the transient charging coil are used together, they can be adapted to charge various power electronic devices.

[0027] For example, a device may include a main charging coil and a transient charging coil. The main charging coil has an output power of 67W, and the transient charging coil has an output power of 30W. However, the ideal charging power for different mobile phones may be 67W, 97W, or 30W, etc. Therefore, the above solution can adapt to the ideal charging power for different devices. For electronic devices requiring 30W charging, only the transient charging coil can be used for charging. For 67W, only the main charging coil can be activated. For electronic devices with an ideal charging power of 97W, both the main charging coil and the transient charging coil can be used simultaneously to achieve a near-powerful charging effect, with the transient charging coil supplementing the power. In this embodiment, the power loss due to the superposition of multiple coils is not considered.

[0028] To achieve the two technical solutions mentioned above, this motorcycle charging system also includes a microprocessor. The microprocessor is used to control the power output, such as controlling the energization of the transient charging coil and the main charging coil. In this embodiment, the microprocessor is connected to the main charging coil and the transient charging coil via a drive circuit.

[0029] The number of outputs from the drive circuit is the same as that of all coils, and its functions include: (1) Load identification: detect the type (e.g., mobile phone / tablet / earphone), and automatically match the power level of 15W / 30W / 67W / 97W through FSK / ASK modem communication (Qi protocol).

[0030] (2) Real-time voltage regulation: The output voltage is dynamically adjusted to maintain stable power based on the acquired signals such as the charging parameters of the electronic device. The charging parameters of the electronic device can be obtained through radio frequency signals.

[0031] In some embodiments, a magnetic array is also included; the magnetic array and the wireless charging module are overlapped. All the transient charging coils have the same output power. Combining the transient charging coils and the main charging coil allows for stepped power output.

[0032] In other embodiments, a magnetic array is also included; the magnetic array and the wireless charging module are overlapped. The output power of the transient charging coil changes linearly with increasing / decreasing power. In this embodiment, the output power of the transient charging coil changes linearly with increasing / decreasing power, which can realize power output of power electronic devices with large variations.

[0033] In both of the above embodiments, the magnetic array can make the transmitting coil of the wireless charger and the receiving coil of the electronic device fit closely and attract each other, ensuring that the center of the transmitting coil and the receiving coil of the electronic device are coincident or partially coincident, thereby minimizing energy loss.

[0034] In some embodiments, the microprocessor is connected to a radio frequency module for acquiring radio frequency signals emitted by the device to be wirelessly charged, the radio frequency signals including at least the charging power of the device to be wirelessly charged; the microprocessor controls the transient charging coil according to the charging power of the device to be wirelessly charged.

[0035] The radio frequency (RF) module includes an RF transmitting module and an RF receiving module. The RF module acquires the RF signal (i.e., the NFC signal of the electronic device) and transmits it to the microprocessor. The RF signal contains the optimal charging power, voltage, and current of the electronic device. The microprocessor uses this data to implement the optimal output coil connection scheme and sends control signals to the drive circuit to control the power output, thereby adjusting to the optimal charging power.

[0036] In some implementations, combined Figure 2 As can be seen, the battery activation circuit includes an input protection circuit, a fast charging identification circuit, a DC-DC circuit, and an output protection circuit connected in sequence; the input terminal of the input protection circuit is used as the end of the battery activation circuit, serving as the activation interface for the power bank; the output terminal of the output protection circuit is connected to the battery.

[0037] The present invention also provides a motorcycle charging control method, including a motorcycle charging system according to any of the above embodiments, the method comprising: The steps for activating a power bank by activating a depleted battery via a battery activation circuit. Steps for wirelessly charging unknown power electronic devices; Charging control steps used to control movement during the charging process of electronic devices.

[0038] Among them, combined Figure 3 It can be seen that the specific steps for activating a depleted battery via the battery activation circuit to activate a portable power bank are as follows: When the battery is low, you must first ensure that the motorcycle has enough fuel. S11: Activate the power bank interface to connect and activate the power bank; Activate the power bank + to connect with the motorcycle battery +; Activate the power bank - to connect with the motorcycle battery +. Among them, activating a mobile power source meets the needs of motorcycle jump-starting; S12: Activate the power bank to output the required voltage and current, and wait for n minutes; the value of n is related to the motorcycle battery, and is generally 1-3 minutes. S13: Start the motorcycle with a dead battery; if the start is successful, proceed to step S14; otherwise, return to step S12. S14: The motorcycle runs continuously for m minutes. The value of m is related to the motorcycle battery and is generally 3-5 minutes. S15: Motorcycle is out of service; disconnect the power bank from its interface.

[0039] Organize the wiring and close the power bank port cover.

[0040] In the process of wirelessly charging an electronic device of unknown power, the motorcycle charging system includes a main charging coil and two transient charging coils. The transient charging coils overlap with the main charging coil, are of equal size, and have a rated output power of 20W. The main charging coil has a rated output power of 67W. Now, a smartphone A needs to be charged, which has an acceptable charging power of 0-120W, and its official charger is 97W. Figure 4 It can be seen that the entire charging system charges smartphone A as follows: S21: Smartphone A is placed in the wireless charging area; S22: The main charging coil senses and starts charging; at this time, the charging power of smartphone A is around 67W. S23: The radio frequency module acquires the NFC signal of smartphone A and extracts its official ideal charging power of 97W; and feeds it back to the microprocessor; S24: The microprocessor sends a drive control signal to drive the circuit, enabling it to drive any one of the transient charging coils to act as a compensation charging coil, bringing it closer to the charging power and accelerating the charging speed; until charging is complete.

[0041] Motorcycle reverse charging refers to the process of a motorcycle charging other electronic devices (such as mobile phones and smartwatches). Due to the relatively poor road conditions and rudimentary shock absorption of motorcycles, the ride is much bumpier than that of a car. Therefore, a fixed structure is needed to secure electronic devices placed on the motorcycle for charging. However, due to differences in the size and model of electronic devices, the fixed structure cannot achieve the desired fixation, leading to problems such as charging cables coming loose and charging ports being damaged. Wireless charging devices have been proposed, but due to the continued vibration, the charging fixation effect is not good, and device movement and vibration still occur. Wireless charging repeatedly disconnects and reconnects in short intervals, easily damaging both the charger and the charging device.

[0042] In the charging control steps for moving during the charging process of an electronic device, the motorcycle charging system consists of 6 transient charging coils and 1 main charging coil. The transient charging coils are evenly arranged around the main charging coil. The transient charging coils and the main charging coil are the same size and have the same output power of 20W. Now, a smartphone B is to be charged. The acceptable charging power range for smartphone B is 0-100W. The charging process occurs while the motorcycle is being ridden on a bumpy road. Figure 5 As can be seen, the specific steps are as follows: S31: Smartphone B is placed in the center of the wireless charging area; S32: The main charging coil senses and starts charging; at this time, the charging power of smartphone B is around 20W; at this time, other surrounding transient charging coils are not working. S33: When smartphone B moves to the first transient charging coil, the first transient charging coil begins to sense and time; S34: When the preset induction period ks is exceeded, the microprocessor controls the first transient charging coil to work and stops driving the main charging coil; where the value of k is 5-10 seconds. S35: When smartphone B moves from the first transient charging coil to the second transient charging coil, the second transient charging coil begins to sense and start timing; S36: When the preset induction period ks is exceeded, the microprocessor controls the second transient charging coil to work and stops driving the first transient charging coil to work; this process is repeated until charging is completed.

[0043] The above solution can prevent the charger from easily leaving the charging area and achieve large-scale charging control.

[0044] The description of the system embodiments above is similar to that of the method embodiments above, and has similar beneficial effects.

Based on this understanding, the technical solutions of the embodiments of this application, or the parts that contribute to related technologies, can be embodied in the form of software products.
