[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0050] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0051] See also Figure 1In a preferred embodiment of the present invention, based on the above problems existing in the prior art, an adaptive energy recovery system is provided, which is applicable to a handheld ultrasound device, comprising:

[0052] Energy recovery module 1, the energy recovery module 1 at least comprises:

[0053] A vibration energy recovery unit 11 is connected to the vibration component of the handheld ultrasound device, and is used to convert the mechanical vibration generated by the vibration component during operation into first electrical energy, and store the first electrical energy in an energy storage unit 13 inside the handheld ultrasound device;

[0054] The thermoelectric energy recovery unit 12 is connected to the heating component of the handheld ultrasound device, and is used to convert the heat generated by the heating component during operation into second electric energy, and store the second electric energy in the energy storage unit 13;

[0055] Environmental sensing modules 2 are respectively arranged in predetermined areas of the handheld ultrasound device to monitor and obtain environmental sensing information around and inside the device;

[0056] The adaptive energy management module 3 is respectively connected to the environmental perception module 2, the energy recovery module 1 and the energy storage unit 13, and is used to output control instructions to the energy recovery module 1 according to the environmental perception information. The control instructions include at least the working modes of the vibration energy recovery unit 11 and the thermoelectric energy recovery unit 12.

[0057] Specifically, in order to address the problem that traditional handheld ultrasound devices rely on battery power, lack energy recovery mechanisms and energy management strategies, and have poor battery life, in this embodiment, an efficient vibration and heat energy recovery mechanism is used to significantly improve the battery life and meet the needs of long-term operation; dynamic energy recovery and energy management are performed through environmental perception information to improve the reliability and efficiency of the device in different usage scenarios.

[0058] As a preferred embodiment, wherein Figure 2 As shown, the vibration energy recovery unit 11 includes:

[0059] The piezoelectric energy collection subunit 111 is used to collect the mechanical vibration generated by the vibration component during operation and convert the mechanical vibration into piezoelectric energy;

[0060] The first DC boost conversion subunit 112 is connected to the piezoelectric energy collection subunit 111 and is used to perform DC boost processing on the piezoelectric energy to obtain the first energy.

[0061] Specifically, in this embodiment, the vibration energy recovery unit 11 can effectively recover and utilize the mechanical vibration energy generated by the equipment during operation, thereby achieving energy recycling and energy saving.

[0062] Furthermore, the piezoelectric energy collection subunit 111 uses high-performance piezoelectric material PZT (such as lead zirconate titanate) ceramic as the piezoelectric element, which is installed in the internal area with frequent vibrations to collect the mechanical vibrations generated by the equipment during operation and convert them into piezoelectric energy.

[0063] The piezoelectric element is installed in an area of ​​the device where vibrations are frequent, such as near a vibration component, to ensure that the mechanical vibrations generated by the device during operation can be fully captured. The output end of the piezoelectric element is connected to the first DC boost conversion subunit 112 to transmit the collected piezoelectric energy to the subsequent processing unit. The piezoelectric energy output is converted by DC boost to achieve a regulated output of the first energy and is stored in the energy storage unit 13. Since the electrical energy output by the piezoelectric element is usually low and unstable, it needs to be boosted and stabilized before it can be used for subsequent energy storage or use.

[0064] The first DC boost conversion subunit 112 uses an efficient DC boost circuit to convert the low voltage, low current electric energy output by the piezoelectric element into high voltage, stable DC electric energy. The converted electric energy is called the first energy and is output to the energy storage unit 13 for storage.

[0065] In this embodiment, the energy storage unit 13 uses an internal battery of the handheld ultrasound device as an energy storage device.

[0066] Piezoelectric materials have high piezoelectric coefficients and stable mechanical properties, and can efficiently convert mechanical vibrations into electrical energy. Appropriate piezoelectric materials can be selected as piezoelectric elements based on the vibration characteristics of the equipment and the working environment to ensure that the vibration frequency can be effectively transmitted and converted into electrical energy.

[0067] As a preferred embodiment, wherein Figure 3 As shown, the thermoelectric energy recovery unit 12 includes:

[0068] Thermoelectric energy collection subunit 121 is used to collect the heat generated by the heating component during operation and convert the heat into thermoelectric energy;

[0069] The second DC boost conversion subunit 122 is connected to the thermoelectric energy collection subunit 121 and is used for performing DC boost processing on the thermoelectric energy to obtain the second energy.

[0070] Specifically, in this embodiment, the thermoelectric energy recovery unit 12 is used to recover the heat generated by the equipment during operation and convert it into electrical energy, thereby achieving energy reuse and energy saving.

[0071] The thermoelectric energy collection subunit 121 uses a Peltier effect element. The Peltier effect element is a device that can directly generate electrical energy using temperature differences. It is attached to key parts of the device that generate heat, such as processors, power modules and other heat-generating components. When these components are working, a large amount of heat is generated, which is absorbed by the Peltier effect element and converted into electrical energy through the Peltier effect.

[0072] Since the thermoelectric energy output by the Peltier effect element is often low and may fluctuate, in order to make it effectively utilized and stored, the thermoelectric output is converted into stable, high-quality electrical energy (i.e., the second energy) through a DC boost conversion and stored in the battery inside the device.

[0073] Furthermore, the heating component can also use copper or aluminum heat sinks. Copper and aluminum heat sinks have good thermal conductivity and can quickly transfer the heat generated by the heating component to the Peltier effect element, thereby improving the thermoelectric conversion efficiency. At the same time, through the efficient heat dissipation mechanism, the temperature of the heating component can be effectively reduced and its service life can be extended.

[0074] As a preferred embodiment, wherein Figure 4 As shown, the first DC boost conversion subunit 112 and the second DC boost conversion subunit 122 respectively include:

[0075] A rectifier circuit 113, wherein the rectifier circuit 113 includes a full-wave rectifier circuit 1131 and a half-wave rectifier circuit 1132;

[0076] A voltage stabilizing circuit 114, wherein the input end of the voltage stabilizing circuit 114 is connected to the output end of the rectifier circuit 113; the voltage stabilizing circuit comprises a step-down DC / DC converter 1141 and a step-up DC / DC converter 1142;

[0077] A first switching control circuit 115, connected to the rectifier circuit 113, for controlling the rectifier circuit 113 to switch between the full-wave rectifier circuit 1131 and the half-wave rectifier circuit 1132 according to a first external control instruction or environmental sensing information;

[0078] The second switching control circuit 116 is connected to the voltage stabilizing circuit 114 and is used to control the voltage stabilizing circuit 114 to switch between the step-down DC / DC converter 1141 and the step-up DC / DC converter 1142 according to the second external control instruction or the feedback signal of the output voltage of the handheld ultrasound device.

[0079] Specifically, in this embodiment, the first DC boost conversion subunit 112 and the second DC boost conversion subunit 122 have the same structure but process different input sources.

[0080] The full-wave rectifier circuit 1131 can use both the positive and negative half-waves of the input signal, and is suitable for high-frequency vibration or stable input scenarios. The half-wave rectifier circuit 1132 only uses one half-wave of the input signal, and is suitable for low-frequency vibration or energy collection under extreme conditions. The rectifier circuit can adaptively adjust the rectifier mode.

[0081] Rectification mode selection:

[0082] Full-wave rectification mode: In the case of high-frequency vibration or stable input, the full-wave rectification circuit 1131 is selected through the first switching control circuit 115 to ensure that both positive and negative half-waves can be fully utilized to improve energy collection efficiency.

[0083] Half-wave rectification mode: Under low-frequency vibration or extreme conditions, the half-wave rectification circuit 1132 is selected by the first switching control circuit 115 to reduce unnecessary losses and optimize rectification efficiency.

[0084] The first switching control circuit 115 can automatically switch between the full-wave rectification mode and the half-wave rectification mode based on preset conditions (such as vibration intensity, voltage fluctuation, etc.) to adapt to different working environments and energy input conditions.

[0085] Furthermore, the rectification efficiency can be further optimized by adjusting the conduction voltage and switching frequency of the rectification diode or transistor switch in the rectification circuit to adapt to the characteristics of different energy sources and load requirements.

[0086] The input end of the voltage stabilizing circuit 114 is connected to the output end of the rectifier circuit 113. The rectified DC power may still fluctuate, which is smoothed by the voltage stabilizing circuit. The voltage stabilizing circuit 114 can use a switching regulator (DCDC converter) to keep the output voltage stable, such as using a buck (Buck) or boost (Boost) DC / DC converter to adjust the voltage to ensure the stability and reliability of the output voltage.

[0087] Furthermore, the DC / DC converter adjusts the output voltage according to the input voltage and load requirements through an adjustable voltage regulator to achieve efficient conversion and transmission of electric energy. By real-time monitoring of the input voltage from the piezoelectric energy harvesting subunit 111 and the thermoelectric energy harvesting subunit 121, the operating parameters of the DC / DC converter (such as duty cycle) are adjusted to ensure the stability and reliability of the input voltage. Through output voltage feedback control, the output voltage is adjusted according to the system load requirements to ensure stable power supply to the core module of the device and optimize energy utilization efficiency.

[0088] As a preferred embodiment, wherein Figure 5 As shown, the environment perception module 2 includes:

[0089] A first temperature sensor 21, used to monitor the internal temperature data of the handheld ultrasound device; and / or

[0090] A second temperature sensor 22, used to monitor the ambient temperature data of the handheld ultrasound device; and / or

[0091] A vibration sensor 23, used to monitor vibration data of the vibration component; and / or

[0092] A light sensor 24 for monitoring ambient light intensity data outside the handheld ultrasound device; and / or

[0093] A position sensor 25, used to monitor the position data of the handheld ultrasound device;

[0094] The environmental perception information includes one or more combinations of internal temperature data, ambient temperature data, vibration data of a vibration component, ambient light intensity data, and position data.

[0095] Specifically, the temperature sensor is integrated into the key internal components and the housing of the handheld ultrasound device to monitor the temperature changes around and inside the device. The temperature sensor is connected to the main control chip of the adaptive energy management module 3 through the I2C interface to read the temperature data in real time and evaluate the potential of heat recovery.

[0096] The vibration sensor can be a highly sensitive MEMS accelerometer, which is fixed near the main vibration source inside the device (i.e. the vibration component mentioned above) to measure the vibration generated during the use of the device. The vibration sensor transmits data to the main control chip through the I2C interface to evaluate the possibility of vibration energy recovery.

[0097] The light sensor and position sensor are also connected to the system main control board through the I2C interface to assist in determining the working environment and status of the device, providing more reference data for accurate energy management.

[0098] Among them, the light sensor can be used to collect ambient light intensity data (Lcurrent) in real time, and combined with the preset light intensity thresholds (such as daytime light intensity threshold, nighttime light intensity threshold, indoor light intensity threshold and outdoor light intensity threshold), to determine whether the current environment of the device is daytime or nighttime and indoors or outdoors. When Lcurrent is greater than or equal to the daytime light intensity threshold, the system determines that it is in daytime mode. Conversely, when Lcurrent is less than or equal to the nighttime light intensity threshold, the system determines that it is in nighttime mode.

[0099] The position sensor can use the IMU unit to provide the motion state and attitude information of the device in real time. Through the real-time collection of accelerometer data (ax, ay, az), the motion state of the device can be analyzed, including whether it is moving, the intensity and direction of movement. At the same time, combined with the gyroscope data, the attitude angle (pitch angle, roll angle, heading angle) of the device can be calculated to determine the installation method or usage attitude of the device. In specific operations, by defining the motion state judgment threshold (such as the static threshold, the motion threshold), and judging whether the device is in a static or moving state according to the real-time changes of the acceleration data. In addition, the acceleration data is analyzed by spectrum analysis methods (such as fast Fourier transform FFT) to identify the main vibration frequency, and the vibration amplitude is calculated by the integration method to judge the stability of the device working environment. If the vibration amplitude and frequency exceed the set threshold, the system will judge that the working environment of the device is relatively unstable and needs to adjust the working strategy or reduce power consumption.

[0100] Furthermore, if the attitude angle of the device deviates from the normal operating range (such as an inclination angle exceeding 30 degrees), the system may need to adjust the working mode of the sensor or send an alarm signal to ensure the safe and stable operation of the device.

[0101] By processing and fusing the data from the light sensor and position sensor, the working environment and status of the device can be judged more accurately. For example, data processing includes: averaging and filtering the light intensity data to eliminate noise interference; filtering and interpolating the accelerometer and gyroscope data to ensure data consistency and stability. Data fusion includes: judging the environmental mode (day / night) based on the light intensity data, and judging the motion state and posture of the device based on the position sensor data, and fusing the results of the two to form a comprehensive state description. For example, if the light intensity is high and the vibration is strong, it is inferred that the device is outdoors during the day and is working frequently; if the light intensity is low and the device is stationary, it is inferred that the device is dormant at night or indoors.

[0102] The adaptive energy management module 3 uses the comprehensive state description of the light sensor and position sensor data to adjust the device's working strategy and energy management in real time, which can achieve more accurate environmental perception and energy management optimization, and improve the device's intelligence level and operating efficiency. For example, during the day and when the device is stationary, the operating frequency can be reduced to save energy; when motion is detected and the environment is unstable, energy allocation can be increased.

[0103] As a preferred embodiment, wherein Figure 6 As shown, an intelligent control model 31 is preset in the adaptive energy management module 3, and the intelligent control model 31 is used to process environmental perception information to obtain control instructions through feedback.

[0104] Specifically, in this embodiment, the adaptive energy management module 3 is based on a preset intelligent control algorithm to adjust the working parameters of the energy recovery device in real time according to the sensor data.

[0105] The intelligent control algorithm is implemented based on a neural network. By training the model, the intelligent control model 31 can determine parameters such as equipment operation status, temperature changes, vibration intensity, etc. according to environmental perception information, thereby dynamically adjusting the energy recovery strategy, which includes the working parameters of the energy recovery device.

[0106] During the model training process, sensors are used to monitor sensor data such as ambient temperature, vibration intensity, and the output power of the piezoelectric energy harvesting subunit 111 and the thermoelectric energy harvesting subunit 121; the energy harvesting efficiency of each module is calculated, and the relationship between environmental parameters and harvesting efficiency is analyzed, and a model is established using a machine learning algorithm (such as a neural network, fuzzy logic). The model uses a control algorithm (such as PID, fuzzy control) to achieve the goal according to the adjustment target, such as maximizing energy harvesting efficiency or optimizing energy balance. According to the environmental parameters and the efficiency model, the working mode of the piezoelectric energy harvesting subunit 111 and the thermoelectric energy harvesting subunit 121 is adjusted in real time, for example, the load resistance of the piezoelectric energy harvesting subunit 111 is adjusted to optimize the conversion of mechanical to electrical energy; the load resistance of the thermoelectric energy harvesting subunit 121 is adjusted to optimize the conversion of temperature difference to electrical energy.

[0107] Furthermore, during the model application process, machine learning algorithms can be used at regular or custom times to continuously perform adaptive learning using historical data to improve the accuracy of predictions and adjustments.

[0108] As a preferred embodiment, wherein Figure 6 As shown, the adaptive energy management module 3 also includes:

[0109] The power distribution unit 32 is connected to the energy storage unit 13. The power distribution unit 32 has a preset correspondence between the working mode of the handheld ultrasound device and the power supply priority of different components. It is used to power local components or all components inside the handheld ultrasound device according to the current working mode of the handheld ultrasound device identified by environmental perception information.

[0110] Specifically, in this embodiment, the power distribution unit 32 presets the priority order of different components of each functional module of the handheld ultrasound device. Through real-time monitoring and adjustment by battery power management, the power supply source of each component can be intelligently switched according to the power status of the device and the usage scenario, ensuring that when the power is insufficient, the core functional modules are powered first, for example, the ultrasound probe, display screen and other core functional modules are given priority in power supply.

[0111] Furthermore, the adaptive energy management module 3 uses a low-power main control chip (such as MCU) as the control core to monitor the output of the piezoelectric energy collection subunit 111 and the thermoelectric energy collection subunit 121 in real time, and adjusts the parameters of the rectification and voltage stabilization circuits to optimize the energy collection efficiency.

[0112] The adaptive energy management module 3 adopts multi-modal energy recovery management, and sets multiple modes, such as high-efficiency recovery mode, low-load mode, emergency power saving mode, etc. By integrating information from different sources such as temperature data and vibration data, the working mode of the recovery device is dynamically adjusted according to the current equipment status and use environment, so as to achieve efficient integration and utilization of energy from different sources, and improve energy recovery efficiency and equipment stability.

[0113] High-efficiency recovery mode: When the device is in a high-load working state, such as using the ultrasonic scanning function continuously for a long time, and the external environment can provide sufficient energy sources (such as large vibration or obvious temperature difference), the system will automatically switch to high-efficiency recovery mode. In this mode, the system will enable the high-efficiency vibration energy recovery mechanism, adjust the parameters of the piezoelectric converter to maximize energy output; at the same time, optimize the operating point of the thermoelectric converter to ensure that the temperature difference is maximized. The conversion into electrical energy. Electromagnetic energy recovery can also be increased by increasing the operating frequency and sensitivity of the electromagnetic energy coupler to improve the energy recovery efficiency. In addition, the system will give priority to energy allocation related to core functions, such as ultrasonic probes and data processing modules, to ensure the stable operation of key functions.

[0114] Low-load mode: When the device is in light use or standby mode, and there are few environmental energy sources and it is impossible to provide conditions for efficient recovery, the system will switch to low-load mode. In this mode, the system will reduce vibration energy recovery activities, reduce the operating frequency of the piezoelectric converter, and reduce energy consumption; reduce the activity of the thermoelectric converter, and only start recovery when there is a significant temperature difference; and enable electromagnetic energy recovery only when significant electromagnetic field changes are detected to reduce unnecessary energy consumption. At the same time, the system will reduce the energy consumption of non-core functions, and more energy will be used to maintain basic operations and monitoring functions to ensure that the device can still operate efficiently when in standby or light use.

[0115] Emergency power saving mode: When the device battery is close to the low power threshold and cannot obtain sufficient ambient energy replenishment, and the remaining operating time of the device needs to be extended to complete critical tasks, the system will switch to emergency power saving mode. In this mode, the system will only enable vibration energy recovery when there is obvious vibration to save energy; enable thermal energy recovery only when there is a significant temperature difference; and completely disable electromagnetic energy recovery unless an abnormally large electromagnetic field change is detected. In addition, the system will shut down all non-core functions to ensure that energy is supplied to the ultrasound probe and necessary communication modules to ensure that critical tasks can be completed smoothly.

[0116] When the device switches from standby mode to long-term continuous use, and the external vibration frequency and temperature difference increase significantly, the system will switch from low-load mode to high-efficiency recovery mode. At this time, the system will activate the high-efficiency vibration energy, thermal energy and electromagnetic energy recovery mechanism, and adjust the operating parameters of each converter to maximize the energy recovery efficiency.

[0117] When the device power drops to near the low power threshold and the ambient energy recovery efficiency is low, the system will switch from high-efficiency recovery mode to emergency power saving mode. In this case, the system will shut down non-core functions, reduce the activity of energy conversion modules, and recover only when there is a significant energy change to ensure that the device can extend the remaining operating time and complete key tasks.

[0118] As a preferred embodiment, the working modes of the vibration energy recovery unit 11 and the thermoelectric energy recovery unit 12 include:

[0119] Mode 1: the vibration energy recovery unit 11 is turned on and the thermoelectric energy recovery unit 12 is turned off; or

[0120] Mode 2: the vibration energy recovery unit 11 is turned on, and the thermoelectric energy recovery unit 12 is turned on; or

[0121] Mode 3: The vibration energy recovery unit 11 is turned off, and the thermoelectric energy recovery unit 12 is turned on.

[0127] Specifically, in this embodiment, the display screen of the handheld ultrasound device provides a user-friendly graphical user interface (GUI) to display information such as the current energy recovery status, power level, temperature and vibration data on the device display screen. The user can also manually adjust parameters and switch modes through the touch screen as needed.

[0128] Furthermore, in order to improve the versatility and scalability of the system, this embodiment adopts a modular design. Each energy recovery unit is an independent unit and can be replaced and upgraded through a standardized interface. Through a standard electrical interface and a universal communication protocol, it is ensured that each energy recovery module 1 is pluggable and interchangeable.

[0129] In addition, the system also integrates solar-assisted recovery function, which is achieved by integrating solar panels on the device casing and photoelectric conversion, and works in coordination with vibration and thermal energy recovery mechanisms to improve the overall energy recovery efficiency.
