Technical Field
[0001] This invention relates to the field of charging management technology, specifically to a wheel self-powered anti-rollover dynamic charging management device. Background Technology
[0002] A wheel-based self-powered dynamic charging management device is a device installed on the wheels of a vehicle that generates electricity using the mechanical energy produced by the rotation of the wheels during vehicle operation, and manages and utilizes the generated electrical energy. It can provide power to on-board electrical equipment or energy storage units without relying on external power supply. To adapt to the characteristics of large speed variations and complex operating conditions during vehicle operation, wheel-based self-powered dynamic charging management devices usually need to have a certain power regulation capability to meet the charging needs under different operating conditions. In the implementation of existing wheel-based self-powered dynamic charging management devices, charging management is usually achieved by adjusting the electrical parameters of the generator output power.
[0003] However, current technology lacks synchronous consideration of changes in the mechanical structure state of the generator during operation. When the vehicle speed, load and other operating conditions change during vehicle operation, there is no effective dynamic coordination mechanism between the generator output power and its structural posture that changes with the operating state. This can easily lead to the charging management process being unable to maintain continuity and stability under complex operating conditions. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a wheel-self-powered anti-rollover dynamic charging management device, which solves the problem of lack of dynamic coordination between generator output power and structural posture that changes with operating conditions, making it difficult to perform collaborative management under complex operating conditions.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a wheel self-powered anti-rollover dynamic charging management device, comprising: A generator that converts mechanical energy into electrical energy as the vehicle rotates with the wheels during driving; The three-phase rectifier module is electrically connected to the generator and converts the three-phase AC power output by the generator into DC power. The voltage detection and overvoltage protection module detects the generator output voltage and provides protection control for the charging process when the detected voltage exceeds a preset threshold. The DPM charging management module is electrically connected to the three-phase rectifier module and the voltage detection and overvoltage protection module, and is used to dynamically adjust the charging power according to the output status of the generator; The servo module is signal-connected to the DPM charging management module and is used to assist in controlling the working status of the generator during the charging management process. The weight is mechanically connected to the generator and forms the fixed end of the generator. During the power generation process, it deflects, and its deflection state changes with the output power of the generator. The DPM charging management module works in conjunction with the servo module to adjust the output power of the generator according to the deflection state of the weight block, thereby controlling the deflection attitude of the weight block.
[0006] Preferably, the weight deflects during the power generation process, and the deflection is characterized by the rotation angle of the weight relative to its initial position.

[0013] Preferably, when the output voltage recovers to below the preset voltage threshold, the voltage detection and overvoltage protection module releases the restriction on the DPM charging management module.
[0014] Preferably, the device is installed inside the vehicle wheel and rotates with the vehicle wheel.
[0015] This invention provides a self-powered, anti-rollover dynamic charging management device for wheels. It has the following advantages: 1. This invention uses the weight block as the fixed end of the generator, so that the deflection attitude of the weight block is related to the output power of the generator. It also introduces the DPM charging management module and the servo module for coordinated control to realize the dynamic adjustment of the generator output power. It constructs an attitude-power linkage management mechanism under the condition of wheel self-powering from the structural and control levels.
[0016] 2. This invention characterizes the deflection state of the weight block by the rotation angle and presets the deflection angle range as the charging management control target. During the operation of the generator, the generator output power is adjusted according to the relationship between the deflection angle of the weight block and the angle range, thereby achieving coordinated control of the attitude of the weight block and the load state of the generator under different vehicle operating conditions.

Detailed Implementation
[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see the appendix Figure 1 -Appendix Figure 9 This invention provides a wheel self-powered anti-rollover dynamic charging management device, comprising: A generator is a device that converts mechanical energy into electrical energy as the vehicle rotates with the wheels while it is in motion. The three-phase rectifier module is electrically connected to the generator and converts the three-phase AC power output by the generator into DC power. The voltage detection and overvoltage protection module detects the generator output voltage and protects the charging process when the detected voltage exceeds a preset threshold. The DPM charging management module is electrically connected to the three-phase rectifier module and the voltage detection and overvoltage protection module, and is used to dynamically adjust the charging power according to the generator's output status. The servo module is connected to the DPM charging management module and is used to assist in controlling the generator's operating status during the charging management process. The weight is mechanically connected to the generator and forms the fixed end of the generator. During the power generation process, it deflects, and its deflection state changes with the output power of the generator. The DPM charging management module works in conjunction with the servo module to adjust the generator's output power based on the deflection state of the weight, thereby controlling the deflection attitude of the weight.
[0021] Furthermore, the device is installed inside the vehicle wheel and rotates with the vehicle wheel.
[0022] Specifically, during vehicle operation, the rotation of the wheels drives the generator, and the alternating current output by the generator is rectified and enters the charging management and voltage detection components. During operation, the voltage detection and overvoltage protection modules monitor the generator's output voltage and apply corresponding control to the charging process when preset conditions are met. During charging management, the DPM charging management module and the servo module coordinate signals to adjust the generator's operating state. Simultaneously, the weight block mechanically connected to the generator deflects during power generation, and its deflection state changes with the generator's output power. This deflection state serves as a reference state during the adjustment process, combined with the generator's output power adjustment process, thus completing the charging management operation under self-powered conditions during vehicle operation.
[0023] The weight deflects during the power generation process, and the deflection is characterized by the rotation angle of the weight relative to its initial position.
[0024] Specifically, the weight is mechanically connected to the generator and forms the fixed end of the generator. During the process of the generator rotating with the wheel and generating electricity, the weight deflects relative to its initial position under the action of gravity and changes in the generator's operating state. The deflection is reflected by the rotation of the weight around its mounting axis. The deflection state is characterized by the rotation angle of the weight relative to its initial position, thereby reflecting the attitude change of the weight during the power generation process and serving as a reference quantity for state judgment during the charging management process.
[0025] The deflection angle is limited to a preset angle range, which is controlled by the DPM charging management module.
[0026] Specifically, based on the representation of the deflection state of the weight block by rotation angle, an angle range for representing the running posture of the weight block is preset, and the angle range is used as the control target in the charging management process. During the operation of the generator, when the DPM charging management module performs charging management control, it compares the current deflection angle of the weight block with the preset angle range, and participates in the subsequent control process based on the comparison result, so that the deflection state of the weight block is adjusted around the preset angle range during operation.
[0027] The DPM charging management module is used to adjust the generator's output power based on the relationship between the deflection angle and a preset angle range.
[0028] Specifically, during the charging management process, the DPM charging management module uses the relationship between the current deflection angle of the weight block and the preset angle range as the basis for adjustment. When the deflection angle of the weight block changes, the DPM charging management module adjusts the output power of the generator accordingly based on the positional relationship between the deflection angle and the preset angle range. It also works in conjunction with the servo module to affect the generator's operating state, so that the generator's output power is adjusted according to the change in the relationship between the deflection angle and the preset angle range.
[0029] The DPM charging management module adjusts the output power according to the generator's output status.
[0030] Specifically, the DPM charging management module acquires the current output status of the generator during the charging management process and uses the output status as a reference for adjusting the generator's output power. When the generator's output status changes, the DPM charging management module adjusts the generator's output power accordingly based on the change in output status. By cooperating with the servo module's signals, the adjustment of output power is applied to the generator's operation process, thereby realizing that the generator's output power is adjusted according to changes in its output status.
[0031] The generator's output status includes output voltage and output current. The DPM charging management module adjusts the charging power based on the output voltage and output current.
[0032] Specifically, the generator's output state is characterized by its output voltage and output current. During the charging management process, the DPM charging management module acquires the generator's output voltage and output current, and uses these as the basis for adjusting the charging power. When the generator's output voltage or output current changes, the DPM charging management module adjusts the charging power accordingly based on these changes, ensuring that the charging management process adapts to changes in the generator's output state.
[0033] The DPM charging management module adjusts the generator load status while regulating the charging power.
[0034] Specifically, the DPM charging management module adjusts the generator's load state simultaneously while adjusting the charging power. The load state changes with the charging power adjustment. By controlling the power transfer state during the charging management process, the DPM charging management module enables the generator to correspond to different load states under different operating conditions, thereby matching the generator's operation process with the charging power adjustment process.
[0035] The voltage detection and overvoltage protection module is used to detect the voltage output by the generator and restrict the operation of the DPM charging management module when the output voltage exceeds a preset voltage threshold.
[0036] Specifically, the voltage detection and overvoltage protection module detects the voltage output by the generator and compares the detected voltage value with a preset voltage threshold. When the generator output voltage exceeds the preset voltage threshold, the voltage detection and overvoltage protection module outputs a limiting signal to the DPM charging management module to restrict the working state of the DPM charging management module, thereby causing the charging management process to enter a restricted state when the output voltage exceeds the preset voltage threshold.
[0037] When the output voltage recovers to below the preset voltage threshold, the voltage detection and overvoltage protection module releases the restriction on the DPM charging management module.
[0038] Specifically, when the voltage output of the generator is detected to return to below the preset voltage threshold, the voltage detection and overvoltage protection module releases the restriction previously imposed on the DPM charging management module, allowing the DPM charging management module to return to normal operation, thus enabling the charging management process to continue after the output voltage returns to below the preset voltage threshold.
[0039] In one specific embodiment, such as Figures 1 to 9 As shown, the device is installed inside the vehicle wheel and operates as the wheel rotates during vehicle movement. The device operates using a wheel-powered self-powered system, which consists of a generator, a three-phase rectifier module, a voltage detection and overvoltage protection module, a DPM charging management module, and a servo module. These modules are connected electrically and by signals to form a complete dynamic charging management system.
[0040] In this embodiment, the generator is a 5220 type generator (QS5228 generator). During vehicle operation, the wheels rotate, causing the generator to rotate synchronously, and the generator outputs three-phase AC power. The three-phase AC power is rectified by a three-phase rectifier module and converted into DC power, which serves as the input power for the charging management system. In this embodiment, the generator's output voltage can reach approximately 37V under high-speed operation and no-load conditions. Considering that the maximum withstand voltage of the DPM charging management module in the charging management system is 28V, a voltage detection and overvoltage protection module is set on the DC output side, and the protection voltage threshold is set to 28V. When the generator output voltage is detected to be greater than 28V, the voltage detection and overvoltage protection module imposes a restriction on the DPM charging management module, causing the charging management system to enter a restricted state. This situation mainly occurs when the battery is fully charged or in trickle charging mode, and the vehicle speed is greater than 120 km / h. In this embodiment, a recovery condition is further set: when the vehicle speed decreases to no more than 100 km / h, the output voltage recovers to below the preset voltage threshold, the overvoltage protection state is released, and the charging management system resumes normal operation.
[0041] The DPM charging management module operates using dynamic charging power management. The BQ24600 charging management chip within the module supports a wide input voltage range of 5V–28V, has a charging current capability of up to 10A, and features high voltage and current regulation accuracy. The BQ24600 chip employs a 1.2MHz NMOS-NMOS synchronous buck converter structure, enabling high energy conversion efficiency during vehicle operation. The DPM charging management module's PCBA board uses a four-layer structure, and its interface structure is as follows... Figure 8As shown.
[0042] In this embodiment, a weight is provided at the fixed end of the generator. The weight is made of tungsten alloy and is mechanically connected to the generator. The weight deflects during power generation, and its deflection state changes with the generator's output power. The weight is in its initial state at 0° and in its full deflection state at 90°. Considering factors such as changes in road conditions and acceleration during vehicle operation, the weight may sway or vibrate during operation. Therefore, in this embodiment, a safety margin of 10°–20° is reserved, and 70°–80° is selected as the optimal safe attitude range for the weight, where 75° corresponds to the maximum deflection angle of the weight. A schematic diagram of the weight's attitude is shown below. Figure 3 As shown.
[0043] In this embodiment, there is a direct correlation between the generator speed and the vehicle speed, with the generator output power varying with the speed. The relationship between vehicle speed and power output is illustrated using a P / V curve, as follows: Figure 2 As shown, the 5220 generator exhibits excellent linearity. Under different vehicle speeds, the weight block can maintain an operating posture close to its maximum deflection angle under the control of the DPM charging management module, thus corresponding to the output power state under different speed conditions. The output power corresponding to the weight block at the maximum deflection angle (safe angle) is defined as the maximum power output. The role of the DPM charging management module is to dynamically adjust the generator output power under different vehicle speeds, so that the weight block maintains its operation within the posture range.
[0044] In this embodiment, the servo module is signal-connected to the DPM charging management module and plays an auxiliary control role. The servo module includes a Vin+ voltage monitoring function and has auxiliary functions such as preventing the generator from being overloaded at low speed and low power, preventing the weight block from overshooting and flipping during charging, and linearity correction. It is used to cooperate with the DPM charging management module to assist in adjusting the generator's operating status.
[0045] During the experiment and testing process, multiple tests were conducted on this embodiment. The charging current output of the generator under different vehicle speed conditions was verified by speed (rV) and charging current (I-charge) tests. The overvoltage protection triggering conditions, battery charging cut-off voltage, battery charging restart voltage, maximum deflection angle of the weight block, and vehicle acceleration performance were also tested.
[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
