Description
Technical Field
[0001] This invention relates to the field of smart door locks, and in particular to a door lock component and a door lock control method. Background Technology
[0002] In the field of smart locks, balancing seamless access with long battery life has always been a key technical challenge. Existing lock designs have many flaws, failing to meet users' core needs for convenience, stability, and low operating costs. Specific issues are as follows: First, the seamless unlocking experience is poor, relying on active user operation. While some existing smart locks claim to support "seamless unlocking," in reality, users still need to perform active operations such as pressing fingerprints, entering passwords, facial recognition, or manually triggering the sensor. This is especially cumbersome when users are carrying heavy objects, have limited mobility, or have their hands occupied, failing to achieve true "lock unlocking by human presence." Furthermore, some locks have high response delays and high false trigger rates in their human body sensor modules, or require users to manually pair their devices via Bluetooth beforehand, severely impacting ease of use. Second, the sensor modules consume a lot of power, relying on built-in batteries. Most existing smart door locks use built-in lithium batteries for continuous power supply for their human body sensing modules. This module needs to maintain a standby monitoring state for a long time, which is one of the core sources of energy consumption for door locks. This results in short battery life, requiring users to frequently replace batteries or charge them, which not only increases the cost of use but also poses safety hazards caused by battery leakage and aging. Some door locks that use light-assisted power supply can only work in strong light environments. In low light or indoor scenarios, they cannot provide stable power to the sensing module and still need to rely on battery power, failing to fundamentally reduce energy consumption.
[0003] Therefore, developing a door lock component that can achieve truly seamless passage, low-energy continuous power supply, balance transient response and long-lasting battery life, and operate stably and reliably has become an urgent technical problem to be solved in this field. Summary of the Invention
[0004] The main objective of this invention is to provide a door lock component and a door lock control method that can improve the convenience and stability of unlocking.
[0005] To achieve the above objectives, the present invention provides a door lock assembly, comprising: A light energy harvesting unit is used to convert light energy into electrical energy; A hybrid energy storage system includes a first energy storage unit and a second energy storage unit, wherein the power density of the first energy storage unit is higher than that of the second energy storage unit, and the energy density of the second energy storage unit is higher than that of the first energy storage unit; The sensing unit, powered by the light energy acquisition unit, is configured to output a wake-up signal when a human body is detected within a preset range. An execution unit is connected to the first energy storage unit and the sensing unit respectively. It is used to receive the wake-up signal and have the first energy storage unit provide instantaneous operating current. After receiving the wake-up signal, the execution unit verifies with an external wireless terminal and performs an unlocking action after successful verification. The light energy acquisition unit is connected to the first energy storage unit and is used to supply energy to the first energy storage unit; the second energy storage unit is connected to the first energy storage unit and is used to supply energy to the first energy storage unit when the voltage of the first energy storage unit is lower than a preset threshold.
[0006] In some embodiments, the power density of the first energy storage unit is at least one order of magnitude higher than the power density of the second energy storage unit; And / or, The energy density of the second energy storage unit is at least an order of magnitude higher than that of the first energy storage unit; And / or, The first energy storage unit is a supercapacitor, and the second energy storage unit is a lithium battery.
[0007] In some embodiments, the execution unit includes a control module, a wireless communication module, and an electronic lock drive module; the power input terminals of the control module, the wireless communication module, and the electronic lock drive module are all connected to the first energy storage unit, which provides instantaneous operating current; the control module is signal-connected to the wireless communication module and the electronic lock drive module, respectively, and is used to control the electronic lock drive module to perform an unlocking action after verification.
[0008] In some embodiments, the sensing unit is a radar detection module, used to emit and receive electromagnetic waves to detect the presence of a human body; And / or, The verification between the execution unit and the external wireless terminal is based on the Bluetooth communication protocol.
[0009] In some embodiments, a low-light energy harvesting chip is disposed between the light energy harvesting unit and the first energy storage unit. The low-light energy harvesting chip is used to start in a low-light environment and convert and store light energy in the first energy storage unit; the start-up voltage of the low-light energy harvesting chip is not higher than 280mV, and / or the start-up power of the low-light energy harvesting chip is not higher than 5 kW. W; And / or, The static power consumption of the sensing unit is no higher than 100. A; And / or, The execution unit takes less than 0.5 seconds to verify with an external wireless terminal after receiving a wake-up signal; And / or, The peak instantaneous operating current of the execution unit provided by the first energy storage unit is not less than 200mA.
[0010] In some embodiments, the sensing unit is powered by both the light energy harvesting unit and the first energy storage unit; wherein, under conditions of illumination, the sensing unit is directly powered by the light energy harvesting unit; under conditions of no illumination or insufficient illumination, the sensing unit is powered by the first energy storage unit, and the sensing unit senses human body signals within a preset range in real time.
[0011] In some embodiments, a buffer capacitor is connected in parallel to the power input terminal of the sensing unit. The buffer capacitor is connected to the light energy harvesting unit, charged by the light energy harvesting unit, and configured to provide surge current at the moment the sensing unit is activated. In this scheme, the corridor is either always lit, in which case the photovoltaic panel can continuously maintain the function of the sensing unit, or the corridor sensor light turns on when a user approaches the door. In this case, the photovoltaic panel initially charges the capacitor, which activates the sensing unit. After that, the photovoltaic panel powers the sensing unit again, so the sensing unit does not need to continuously sense, because there is no need to sense when the corridor light is off, and there is likely no one there. At this time, the photovoltaic panel's energy is also insufficient, so the sensing unit cannot be turned on. The addition of the capacitor is to quickly turn on the sensing unit in the first few seconds when the corridor light turns on.
[0012] In some embodiments, the door lock assembly includes a base, a photovoltaic material layer, and a light-transmitting layer. The base has a front wall surface, the photovoltaic material layer fully covers the front wall surface, and the light-transmitting layer is attached to the side of the photovoltaic material layer opposite to the front wall surface.
[0013] In some embodiments, the door lock assembly further includes a light-transmitting touch-sensing layer located between the photovoltaic material layer and the light-transmitting layer for acquiring touch signals on the light-transmitting layer.
[0014] A second aspect of this application also provides a door lock control method for any of the door lock components described above, comprising the following steps: The light energy harvesting unit converts ambient light energy into electrical energy and prioritizes charging the first energy storage unit; When the voltage of the first energy storage unit reaches the full charge threshold, the excess energy will be used to charge the second energy storage unit. The sensing unit continuously monitors the presence signal of a human body within a preset range under the power supply of the light energy acquisition unit, and outputs a wake-up signal when the presence of a human body is detected. After receiving the wake-up signal, the execution unit is woken up from the dormant state by the instantaneous operating current provided by the first energy storage unit; The execution unit verifies with an external wireless terminal; After successful verification, the execution unit performs the unlocking action; When the voltage of the first energy storage unit is lower than a preset threshold, the second energy storage unit replenishes the first energy storage unit with electrical energy.
[0015] Compared with existing technologies, the advantages of this invention are as follows: In the door lock component of this solution, the sensing unit continuously monitors the presence signal of a human body within a preset range in real time, and outputs a wake-up signal when a human body is detected. After receiving the wake-up signal, the execution unit verifies with an external wireless terminal, and performs the unlocking action after successful verification. Therefore, users do not need to perform any active operations (such as pressing a fingerprint, entering a password, or facial recognition) when approaching the door lock, and identity verification and unlocking can be automatically completed, achieving a seamless "people approach, lock opens" passage experience, which is especially suitable for scenarios where users are carrying heavy objects or have limited mobility.
[0016] In this door lock assembly, the sensor unit is powered directly by the light energy harvesting unit. Since users are typically in a well-lit corridor or lobby area (whether by natural light or indoor lighting) before opening the door, the light energy harvesting unit continuously powers the sensor unit, keeping it in real-time monitoring mode. Even if the sensor unit is temporarily inactive at night or in darkness, users will not attempt to open the door in such environments, thus not affecting the normal operation of the lock. This structure reduces the sensor unit's reliance on independent batteries or a secondary energy storage unit, thereby reducing system energy consumption and cost.
[0017] In this door lock assembly, the hybrid energy storage system includes a first energy storage unit and a second energy storage unit. The first energy storage unit has a higher power density than the second energy storage unit, while the second energy storage unit has a higher energy density than the first energy storage unit. The execution unit is connected to the first energy storage unit and receives instantaneous operating current from it. This structure utilizes the high power density of the first energy storage unit to provide sufficient instantaneous high current when the execution unit is activated, meeting the transient power consumption requirements for authentication with external wireless terminals and unlocking actions. Simultaneously, the high energy density of the second energy storage unit provides long-term energy reserves for the system, achieving synergistic optimization of high-power transient response and high-energy long-term endurance.
[0018] In the door lock assembly of this solution, the second energy storage unit is connected to the first energy storage unit and configured to supply energy to the first energy storage unit when its voltage is lower than a preset threshold. This structure ensures that even after multiple wake-up discharges or voltage drops due to self-discharge, the second energy storage unit can still replenish the first energy storage unit's energy in a timely manner, ensuring that its voltage is always maintained above the threshold that can output instantaneous operating current. This guarantees that the execution unit can obtain a reliable instantaneous high current supply every time a human body senses wake up, avoiding door opening failures caused by the depletion of energy in the first energy storage unit, and improving the stability and reliability of the system.

[0024] In the field of smart locks, balancing seamless access with long battery life has always been a key technological challenge. Existing lock designs suffer from numerous flaws, failing to meet users' core needs for convenience, stability, and low operating costs. Specific problems include: First, the seamless unlocking experience is poor, relying on active user intervention. While some smart locks claim to support "seamless unlocking," users still need to perform actions such as pressing fingerprints, entering passwords, facial recognition, or manually triggering the sensor. This is especially cumbersome when users are carrying heavy objects, have limited mobility, or have their hands occupied, making it impossible to achieve true "lock unlocking by human presence." Furthermore, some locks have high latency and false trigger rates in their human body sensor modules, or require users to manually pair their devices via Bluetooth beforehand, severely impacting usability. Second, the sensor modules consume a lot of power, relying on built-in batteries. Most existing smart door locks use built-in lithium batteries for continuous power supply for their human body sensing modules. This module needs to maintain a standby monitoring state for a long time, which is one of the core sources of energy consumption for door locks. This results in short battery life, requiring users to frequently replace batteries or charge them, which not only increases the cost of use but also poses safety hazards caused by battery leakage and aging. Some door locks that use light-assisted power supply can only work in strong light environments. In low light or indoor scenarios, they cannot provide stable power to the sensing module and still need to rely on battery power, failing to fundamentally reduce energy consumption.
[0025] See Figure 1-2This application provides a door lock component 100 for locking and unlocking doors. Specifically, the door lock component 100 can be used for various common door lock applications, including home entrance doors, room doors, courtyard doors, company gates, office doors, and others. The door lock component 100 can automatically lock and unlock doors. In some scenarios, it can also automatically lock and unlock doors as well as manually unlock them. In one application, a seamless unlocking mechanism is required when a user enters or leaves a door. That is, when the user approaches the door, the door lock component 100 automatically unlocks, and the user only needs to turn and pull the door handle to open the door, or simply pull the handle, without requiring additional verification or operation to unlock. For ease of description, the following example focuses on a home entrance door, specifically the scenario where a user needs seamless unlocking when entering the house from the outside (in other scenarios, seamless unlocking can also be performed when leaving the house from the inside to the outside). Specifically, in this application, the door lock assembly 100 includes a light energy harvesting unit 110, a hybrid energy storage system 120, a sensing unit 130, and an execution unit 140.
[0026] The light energy harvesting unit 110 is used to convert light energy into electrical energy. The specific materials, structure, photoelectric conversion parameters, and arrangement position of the light energy harvesting unit 110 on the door lock assembly 100 can be determined according to the actual application scenario, panel shape, and system power supply requirements. In some embodiments, the light energy harvesting unit 110 may include a photoelectric conversion body 111, the material of which may be weak-light hydrogenated amorphous silicon, stacked monocrystalline PERC silicon-based material, perovskite-organic hybrid photovoltaic material, or III-V compound semiconductor material, etc. In some embodiments, the photoelectric conversion body 111 may be a rectangular flexible thin film shape, a micro modular array shape, or a bendable irregular thin film shape, and may be located on the entire front wall of the door lock base 150 facing the outdoors, in the reserved mounting groove in the upper half of the door lock panel, on the outer surface of the door lock handle, or in the gap area of the door lock panel buttons. In some embodiments, the photoelectric conversion parameters of the photoelectric conversion body 111 can be as follows: photoelectric conversion efficiency not less than 6% and open-circuit voltage not less than 280mV in a 5 lux indoor low-light environment, capable of stably outputting a working current that meets the static power consumption of the sensing unit 130; photoelectric conversion efficiency not less than 12% in a 1000 lux natural direct light environment, enabling rapid replenishment of the energy storage unit. For example, in this embodiment, the photoelectric conversion body 111 can be a low-light type hydrogenated amorphous silicon material, and is in the form of a continuous and uniform thin film, and is at least fully covered on the front wall surface of the door lock assembly 100 on the side closest to the outdoors. Its specific parameters are: overall film thickness 0.3mm, spectral response range covering the entire visible light band of 350nm-780nm, photoelectric conversion efficiency ≥8% in a 5 lux corridor low-light environment, open-circuit voltage ≥320mV, and output power per unit area ≥10. W / cm 2 Under direct natural light at 1000 lux, the photoelectric conversion efficiency is ≥12%, which can simultaneously meet the continuous power supply requirements of the sensing unit 130 and the priority charging requirements of the energy storage unit.
[0027] The hybrid energy storage system 120 includes at least two energy storage units: a first energy storage unit 121 and a second energy storage unit 122. The first energy storage unit 121 has a higher power density than the second energy storage unit 122, while the second energy storage unit 122 has a higher energy density than the first energy storage unit 121. That is, the first energy storage unit 121 has a better instantaneous high-current output capability than the second energy storage unit 122, enabling it to quickly respond to high-power instantaneous output requests from the execution unit 140 for wake-up, authentication, and unlocking actions. For example, the first energy storage unit 121 can be a double-layer supercapacitor, a lithium-ion capacitor, or a graphene-based hybrid supercapacitor. The second energy storage unit 122 has a higher energy storage capacity than the first energy storage unit 121, providing long-term energy reserves and replenishment support for the system. Specifically, the second energy storage unit 122 can be connected to the first energy storage unit 121 to supply energy to the first energy storage unit 121 when the voltage of the first energy storage unit 121 is lower than a preset threshold. For example, the second energy storage unit 122 can be a lithium iron phosphate battery, a lithium manganese battery, or a lithium thionyl chloride battery.
[0028] The specific types of the first energy storage unit 121 and the second energy storage unit 122 can be determined according to the actual application scenario, the power consumption requirements of the door lock, and the installation space, as long as they meet the aforementioned differentiated matching requirements for power density and energy density. In this embodiment, the first energy storage unit 121 is a supercapacitor, with specific parameters such as: rated voltage 5.5V, nominal capacity 5F, power density ≥10kW / kg. The first energy storage unit 121 has a higher power density than the second energy storage unit 122, and can stably output a peak instantaneous operating current ≥500mA within milliseconds, improving the problems of voltage drop, unlocking failure, and lifespan degradation caused by instantaneous high current discharge in related technologies; cycle life ≥100,000 times. In this embodiment, the light energy harvesting unit 110 is connected to the first energy storage unit 121 to supply power to the first energy storage unit 121. The second energy storage unit 122 can be a lithium iron phosphate soft-pack battery with the following parameters: rated voltage 3.7V, nominal capacity 500mAh, energy density ≥160Wh / kg, which is higher than the energy density of the first energy storage unit 121, and monthly self-discharge rate ≤3%. It can continuously replenish the first energy storage unit 121 with power when the voltage of the first energy storage unit 121 is lower than a preset threshold, thus ensuring the long-term stable operation of the door lock system.
[0029] The sensing unit 130 is powered by the light energy harvesting unit 110 and can be paired with the first energy storage unit 121 as a backup power source, depending on the application scenario. The sensing unit 130 is configured to output a stable wake-up signal to the execution unit 140 when it detects a human body within a preset range. The sensing method of the sensing unit 130 can be selected according to the application scenario, installation environment, and power consumption requirements of the door lock, ensuring that the static power consumption in the aforementioned embodiment does not exceed 100 kWh. A meets the low-power design requirements. For example, the sensing unit 130 can capture human signals through infrared sensing, radar sensing, ultrasonic sensing, camera image recognition sensing, or other methods that can detect the presence of a human body; among them, the radar sensing scheme can detect human micro-movement signals by emitting and receiving electromagnetic waves, and is not affected by ambient light, temperature, or dust, with a low false trigger rate and fast response speed.
[0030] The operating mode of the sensing unit 130 can be flexibly configured. It can adopt an all-weather real-time sensing mode, continuously monitoring human body signals in the area in front of the door to achieve human body detection with the support of dual power supply from the light energy acquisition unit 110 and the first energy storage unit 121; or it can adopt a condition-triggered sensing mode, which only starts sensing when the preset trigger conditions are met (in this case, the sensing unit 130 can be powered only by the light energy acquisition unit 110). For example, when adapting to the corridor voice control / human body sensor light scenario, the sensing detection is only activated when there is light in the corridor environment and the light energy acquisition unit 110 can stably output power, further reducing the static energy consumption of the system. The sensing unit 130 is located on the outdoor side of the door lock assembly 100, and its detection direction is facing the user's passage direction outside the door, which can ensure that the detection range completely covers the preset area in front of the door; when the outdoor user approaches the door lock assembly 100 to within the preset distance range, the sensing unit 130 can accurately capture the human body presence signal, and then generate and output a wake-up signal to the execution unit 140, providing trigger instructions for subsequent contactless authentication and unlocking actions.
[0031] The execution unit 140 is electrically connected to the power supply output terminal of the first energy storage unit 121 and the signal output terminal of the sensing unit 130, and is the core control and execution center of the door lock assembly 100's contactless unlocking logic. The core function of the execution unit 140 is as follows: after receiving the wake-up signal output by the sensing unit 130, the first energy storage unit 121 provides instantaneous operating current to quickly wake up the user from deep sleep state to working state. After waking up, it actively establishes an encrypted communication link with the user's external wireless terminal and completes identity verification. Finally, after successful verification, it drives the lock body mechanical mechanism to perform the unlocking action, realizing contactless access for the user without any manual operation such as pressing fingerprints, entering passwords, or facial recognition.
[0032] In some embodiments, the execution unit 140 may include three core components: a control module 141, a wireless communication module 142, and an electronic lock drive module 143. The power input terminals of the control module 141, the wireless communication module 142, and the electronic lock drive module 143 are all connected to the power output terminal of the first energy storage unit 121. All instantaneous operating currents are supplied by the high-power-density first energy storage unit 121. The control module 141 is signal-connected to the wireless communication module 142 and the electronic lock drive module 143, respectively, and serves as the logic center of the entire process, coordinating the timing control and command output of wake-up response, encryption verification, and unlocking actions.
[0033] The specific selection of each component of the execution unit 140 can be flexibly adjusted according to the power consumption requirements, functional configuration, and installation space of the door lock, as long as it meets the core requirements of instantaneous power supply, rapid verification, and reliable unlocking of this solution. For example, the control module 141 can be a low-power MCU chip, an embedded control chip, or an FPGA control chip; the wireless communication module 142 can be a Bluetooth communication module, a UWB ultra-wideband communication module, or an NFC near-field communication module. Among them, the verification scheme based on the Bluetooth communication protocol has the advantages of wide compatibility with consumer terminals, low power consumption, fast connection and pairing speed, and stable encryption performance, making it the preferred implementation method for the contactless unlocking scenario of this solution; the electronic lock drive module 143 can be a motor drive chip paired with a DC geared lock body motor, a motor drive chip paired with a stepper motor, or an electromagnetic drive lock body module.
[0034] The core operating parameters of the execution unit 140 must strictly match the system architecture requirements of this solution. Specifically, they must meet the following requirements: after receiving the wake-up signal from the sensing unit 130, the time required to complete the full-process encrypted authentication with the external wireless terminal is less than 0.5 seconds, ensuring that the user can complete the authentication and unlocking actions from entering the sensing range to arriving at the door. The instantaneous peak operating current provided by the first energy storage unit 121 is not less than 200mA, which can simultaneously cover the peak power consumption of the wireless communication module 142 during the authentication process and the peak power consumption of the electronic lock drive module 143 during the unlocking action, ensuring stable power supply with no voltage drop throughout the entire process.
[0035] In this embodiment, the control module 141 can use an STM32L0 series 32-bit low-power MCU chip, with a static power consumption as low as 0.5μA in deep sleep mode. Only the wake-up signal detection channel is reserved for standby, and the entire chip can be quickly started within 1ms after receiving the wake-up signal. The wireless communication module 142 can use a Bluetooth 5.3 low-power communication module, and the encrypted authentication with the external pre-authorized wireless terminal takes no more than 0.3 seconds, which fully meets the rapid authentication requirements of this solution. The electronic lock drive module 143 can use a door lock dedicated motor drive chip paired with a DC geared lock body motor with a rated torque of 2N·m, and the unlocking action response time does not exceed 0.2 seconds. The execution unit 140 is provided with instantaneous operating current by the first energy storage unit 121, and the peak output current can reach 500mA, which fully covers the system peak current requirement of not less than 200mA and can stably support the instantaneous power consumption requirements of the entire wake-up, authentication, and unlocking process. The execution unit 140 is normally in a deep sleep state and only wakes up to work after receiving a wake-up signal. After the action is completed, it immediately switches to sleep mode, which not only achieves high response speed for contactless unlocking, but also reduces the static power consumption of the system and is compatible with the low power supply architecture of this solution.
[0036] In the door lock assembly 100 of this embodiment, the sensing unit 130 continuously monitors the presence of a human body within a preset range in real time, and outputs a wake-up signal when a human body is detected. After receiving the wake-up signal, the execution unit 140 verifies with an external wireless terminal, and performs the unlocking action after successful verification. Thus, users can automatically complete identity verification and unlocking without any active operation (such as pressing a fingerprint, entering a password, or facial recognition) when approaching the door lock, achieving seamless access, which is especially suitable for scenarios where the user is carrying heavy objects or has limited mobility.
[0037] In this embodiment of the door lock assembly 100, the sensing unit 130 is powered directly by the light energy collection unit 110. Since users are usually in a corridor or hallway area with ambient light (whether natural light or indoor lighting) before opening the door, the light energy collection unit 110 can continuously power the sensing unit 130, keeping it in a real-time monitoring state. Even if the sensing unit 130 is temporarily not working at night or under no-light conditions, users will not come to open the door in such environments, so it will not affect the normal use of the door lock. This structure reduces the dependence of the sensing unit 130 on an independent battery or the second energy storage unit 122, thereby reducing system energy consumption and cost. In this embodiment of the door lock assembly 100, the hybrid energy storage system 120 includes a first energy storage unit 121 and a second energy storage unit 122. The power density of the first energy storage unit 121 is higher than that of the second energy storage unit 122, and the energy density of the second energy storage unit 122 is higher than that of the first energy storage unit 121. The execution unit 140 is connected to the first energy storage unit 121 and is provided with instantaneous operating current by the first energy storage unit 121. This structure utilizes the high power density of the first energy storage unit 121 to provide sufficient instantaneous high current when the execution unit 140 is woken up, meeting the transient power consumption requirements for authentication with external wireless terminals and unlocking actions. Simultaneously, the high energy density of the second energy storage unit 122 provides long-term energy reserves for the system, achieving synergistic optimization of high-power transient response and high-energy long-term battery life. In the door lock assembly 100 of this embodiment, the second energy storage unit 122 is connected to the first energy storage unit 121 and configured to supply power to the first energy storage unit 121 when its voltage is below a preset threshold. This structure ensures that even after multiple wake-up discharges or voltage drops due to self-discharge, the second energy storage unit 122 can promptly replenish the first energy storage unit 121's energy, ensuring its voltage remains above the threshold for outputting instantaneous operating current. This guarantees that the execution unit 140 receives a reliable instantaneous high current supply each time it is woken up by human body induction, preventing door opening failures due to energy depletion of the first energy storage unit 121 and improving the system's stability and reliability.
[0038] In some embodiments, the power density of the first energy storage unit 121 is at least an order of magnitude higher than that of the second energy storage unit 122. The core purpose of this parameter limitation is to achieve complete functional decoupling between the two types of energy storage units, ensuring that the first energy storage unit 121 can independently handle the instantaneous high current output demand, and preventing the second energy storage unit 122 from participating in transient power consumption scenarios. A power density difference of at least an order of magnitude (i.e., 10 times or more) means that the instantaneous discharge capability of the first energy storage unit 121 is far superior to that of the second energy storage unit 122, and it can release a large current that meets the needs of the execution unit 140 within milliseconds, while the second energy storage unit 122 does not have to bear the risk of lifespan degradation and voltage drop caused by high current discharge. For example, the power density of the first energy storage unit 121 is 10kW / kg and the power density of the second energy storage unit 122 is 0.8kW / kg (a difference of 12.5 times); the power density of the first energy storage unit 121 is 15kW / kg and the power density of the second energy storage unit 122 is 1kW / kg (a difference of 15 times); the power density of the first energy storage unit 121 is 8kW / kg and the power density of the second energy storage unit 122 is 0.5kW / kg (a difference of 16 times), etc. All the schemes achieve functional separation of transient power supply and long-term storage through significant differences in power density.
[0039] In some embodiments, the energy density of the second energy storage unit 122 is at least an order of magnitude higher than that of the first energy storage unit 121. This limitation aims to allow the second energy storage unit 122 to fully leverage its long-term energy storage advantages and provide stable power replenishment support for the system. The at least one order of magnitude difference in energy density ensures that the energy storage capacity of the second energy storage unit 122 is significantly higher than that of the first energy storage unit 121, enabling it to continuously replenish the first energy storage unit 121 under extreme conditions such as low light or no light, ensuring long-term system operation without frequent charging or replacement of energy storage components. For example, the energy density of the second energy storage unit 122 is 160Wh / kg, while the energy density of the first energy storage unit 121 is 8Wh / kg (a difference of 20 times); the energy density of the second energy storage unit 122 is 200Wh / kg, while the energy density of the first energy storage unit 121 is 10Wh / kg (a difference of 20 times); the energy density of the second energy storage unit 122 is 120Wh / kg, while the energy density of the first energy storage unit 121 is 6Wh / kg (a difference of 20 times), etc. Through significantly superior energy density, the core requirement of long-term system endurance is achieved.
[0040] In some embodiments, the first energy storage unit 121 is a supercapacitor, and the second energy storage unit 122 is a lithium battery. This selection scheme is based on the inherent characteristics of the two types of energy storage devices to achieve synergy between power and energy characteristics. The supercapacitor, as the first energy storage unit 121, has the core advantages of high power density, fast charging and discharging speed, long cycle life (typically ≥100,000 times), and excellent low-temperature performance. It can match the instantaneous high current demand of the execution unit 140 during the wake-up, verification, and unlocking processes, and frequent charging and discharging will not significantly affect its performance. The lithium battery, as the second energy storage unit 122, has the outstanding characteristics of high energy density, low self-discharge rate (monthly self-discharge rate ≤3%), and large storage capacity. It can store the electrical energy converted by the light energy collection unit 110 for a long time and replenish the energy in time when the voltage of the first energy storage unit 121 is insufficient, providing a stable energy reserve for the system. Among them, the supercapacitor can be selected from specific embodiments such as double-layer supercapacitor, lithium-ion capacitor, graphene-based hybrid supercapacitor, etc., and the lithium battery can be selected from specific embodiments such as lithium iron phosphate battery, lithium manganese battery, lithium thionyl chloride battery, etc. All selections can meet the synergistic optimization goal of "high power transient response + high energy long-term endurance", and all are mature commercial devices with the advantages of controllable cost and easy integration.
[0041] The sensing unit 130 is powered by the light energy acquisition unit 110 and can be paired with the first energy storage unit 121 as a backup power source, depending on the application scenario. The sensing unit 130 is configured to output a stable wake-up signal to the execution unit 140 when it detects the presence of a human body within a preset range. The working mode of the sensing unit 130 can be flexibly configured. It can adopt an all-weather real-time sensing mode, continuously monitoring human body signals in front of the door area with the support of dual power supply from the light energy acquisition unit 110 and the first energy storage unit 121; or it can adopt a condition-triggered sensing mode, which starts sensing only when the preset trigger conditions are met (in this case, the sensing unit 130 can be powered only by the light energy acquisition unit 110). For example, when adapting to the corridor voice control / human body sensor light scenario, the sensing detection is only activated when there is light in the corridor environment and the light energy acquisition unit 110 can stably output power, further reducing the static energy consumption of the system. The sensing unit 130 is located on the outdoor side of the door lock assembly 100. Its detection direction faces the user's passage direction outside the door, which can ensure that the detection range completely covers the preset area in front of the door. When the outdoor user approaches the door lock assembly 100 to within the preset distance range, the sensing unit 130 can accurately capture the human presence signal, and then generate and output a wake-up signal to the execution unit 140, providing a trigger command for subsequent contactless authentication and unlocking actions.
[0042] In some embodiments, the sensing unit 130 is a radar detection module 131, used to emit and receive electromagnetic waves to detect the presence of a human body. In related technologies, human infrared detection modules are easily affected by ambient temperature, dust, and obstructions, resulting in a high false trigger rate. Furthermore, they cannot detect stationary human bodies and are unsuitable for the needs of contactless unlocking scenarios. In this solution, the radar detection module 131 emits electromagnetic waves and receives reflected echoes, enabling accurate detection of human presence signals within a preset range, including characteristic signals such as subtle movements and breathing. It is unaffected by ambient light, temperature, or dust, achieving all-weather, high-accuracy human presence detection, avoiding false triggers or missed detections, and ensuring timely output of a wake-up signal when a user approaches, guaranteeing contactless passage. Specific embodiments of the radar detection module 131 that can be used include a 24GHz millimeter-wave radar module, a 5.8GHz microwave radar module, and a 77GHz millimeter-wave radar module.
[0043] In some embodiments, the static power consumption of the sensing unit 130 is not higher than 100 kWh. A. In related technologies, the static power consumption of the sensing module is too high, and the output power of the light energy acquisition unit 110 cannot cover its standby power consumption, still requiring the energy storage unit to consume power. In this solution, the static power consumption is no higher than 100 kWh. The limitation of A ensures that the continuous standby power consumption of the sensing unit 130 remains at an extremely low level. The output power of the light energy harvesting unit 110 in typical low-light indoor environments can completely cover its standby power consumption, enabling continuous power supply to the sensing unit 130 without consuming the power of the second energy storage unit 122, further reducing system energy consumption and cost. For example, the static power consumption is 100... A's sensing module solution has a static power consumption of 50 kWh. A's sensing module solution has a static power consumption of 10. All sensing module solutions in Group A meet the requirement that static power consumption is no higher than 100 kWh. A's requirements.
[0044] In some embodiments, the sensing unit 130 is jointly powered by the light energy harvesting unit 110 and the first energy storage unit 121. Specifically, under illumination, the sensing unit 130 is directly powered by the light energy harvesting unit 110; under conditions of no light or insufficient light, the sensing unit 130 is powered by the first energy storage unit 121 (or, in other embodiments, by the second energy storage unit 122). The sensing unit 130 senses human body signals within a preset range in real time. In related technologies, a single light-powered mode will result in a detection blind spot in the absence of light, making it impossible to achieve all-weather monitoring. This solution adopts a dual-powered automatic switching mode. When there is light, the light energy acquisition unit 110 directly powers the sensing unit 130 without consuming the energy of the energy storage unit, thus reducing system energy consumption. When there is no light or insufficient light, it automatically switches to the first energy storage unit 121 to power the sensing unit 130, ensuring that the sensing unit 130 can sense human signals within a preset range in real time around the clock, while avoiding the consumption of the long-term energy storage of the second energy storage unit 122, thus taking into account both low energy consumption and all-weather monitoring requirements.
[0045] In some embodiments, a buffer capacitor 132 is connected in parallel to the power input terminal of the sensing unit 130. The buffer capacitor 132 is connected to the light energy harvesting unit 110 and is charged by the light energy harvesting unit 110 to provide surge current at the moment the sensing unit 130 is started. In related technologies, in the scenario of corridor sensor lights, the output power of the light energy acquisition unit 110 cannot instantly meet the surge current requirements of the sensor unit 130 when the light is turned on, which easily leads to the problem of delayed start-up and failure of the sensor unit 130 to work properly. In this solution, a buffer capacitor 132 is connected in parallel at the power input terminal of the sensor unit 130. When there is light, the light energy acquisition unit 110 can charge the buffer capacitor 132 to store electrical energy. When the corridor sensor light is turned on and the ambient light suddenly increases, the buffer capacitor 132 can release the surge current at the moment the sensor unit 130 starts up, supporting the sensor unit 130 to start up quickly and enter the working state without waiting for the output of the light energy acquisition unit 110 to stabilize. This is suitable for the application scenarios of corridor sound-controlled lights and human body sensor lights. At the same time, the sensor unit 130 does not need to be in standby mode, further reducing the static energy consumption of the system.
[0046] The execution unit 140 is electrically connected to the power supply output terminal of the first energy storage unit 121 and the signal output terminal of the sensing unit 130, and is the core control and execution center of the door lock assembly 100's contactless unlocking logic. The core function of the execution unit 140 is as follows: after receiving the wake-up signal output by the sensing unit 130, the first energy storage unit 121 provides instantaneous operating current to quickly wake up the user from deep sleep state to working state. After waking up, it actively establishes an encrypted communication link with the user's external wireless terminal and completes identity verification. Finally, after successful verification, it drives the lock body mechanical mechanism to perform the unlocking action, realizing contactless access for the user without any manual operation such as pressing fingerprints, entering passwords, or facial recognition.
[0047] In some embodiments, the execution unit 140 may include three core components: a control module 141, a wireless communication module 142, and an electronic lock drive module 143. The power input terminals of the control module 141, the wireless communication module 142, and the electronic lock drive module 143 are all connected to the power output terminal of the first energy storage unit 121, and all instantaneous operating current is supplied uniformly by the high-power-density first energy storage unit 121. The control module 141 is signal-connected to both the wireless communication module 142 and the electronic lock drive module 143, serving as the central logic unit for the entire process, coordinating the timing control and command output of wake-up response, encryption verification, and unlocking actions. In some embodiments, the verification between the execution unit 140 and the external wireless terminal is based on the Bluetooth communication protocol. In related technologies, wireless authentication protocols suffer from slow connection speeds, high power consumption, and poor terminal compatibility, failing to meet the rapid authentication requirements of contactless unlocking. This solution utilizes a Bluetooth communication protocol characterized by low power consumption, high compatibility, strong encryption, and fast connection speed. After the execution unit 140 is woken up, it can quickly establish an encrypted communication connection with external wireless terminals such as the user's mobile phone or smartwatch, completing identity verification without requiring manual pairing by the user, thus meeting the core requirement of contactless access. Specific embodiments of the Bluetooth communication protocol that can be used include Bluetooth 4.2, Bluetooth 5.0, and Bluetooth 5.3 Low Energy.
[0048] In some embodiments, the time taken for the execution unit 140 to verify with the external wireless terminal after receiving the wake-up signal is less than 0.5 seconds. In related technologies, wireless authentication takes too long, and the user may not have completed authentication by the time they reach the door, thus failing to achieve truly seamless access. The limitation of less than 0.5 seconds in this solution ensures that the execution unit 140 can complete authentication and unlocking actions as soon as the user walks from the sensing range to the door after receiving the wake-up signal, achieving seamless access without any waiting delay. For example, solutions with a verification time of 0.5 seconds, 0.3 seconds, and 0.2 seconds all meet the requirement of less than 0.5 seconds.
[0049] In some embodiments, the peak instantaneous operating current provided by the first energy storage unit 121 to the execution unit 140 is not less than 200mA. In related technologies, insufficient instantaneous output current from the energy storage unit cannot simultaneously meet the peak power consumption requirements of wireless communication and lock body drive, easily leading to voltage drops and unlocking failures. The requirement of a peak instantaneous operating current of not less than 200mA in this solution ensures that the first energy storage unit 121 can stably output sufficient peak current, simultaneously covering the verification peak power consumption of the wireless communication module 142 and the unlocking peak power consumption of the electronic lock drive module 143, ensuring stable power supply and preventing unlocking failures. For example, solutions with a peak instantaneous operating current of 200mA, 500mA, and 1000mA all meet the requirement of a peak instantaneous operating current of not less than 200mA.
[0050] In some embodiments, the door lock assembly 100 includes a base 150, a photovoltaic material layer 111, and a light-transmitting layer 151. The base 150 has a front wall surface, the photovoltaic material layer 111 fully covers the front wall surface, and the light-transmitting layer 151 is attached to the side of the photovoltaic material layer 111 facing away from the front wall surface. In related technologies, the photovoltaic material of the door lock panel is only set in a local area, resulting in a small light-receiving area and low light energy collection efficiency, which cannot provide a continuous and stable power supply for the sensing unit 130. In this solution, the photovoltaic material layer 111 fully covers the front wall surface of the base 150, increasing the light-receiving area and thus improving the light energy collection efficiency. The light-transmitting layer 151 can protect the internal photovoltaic material layer 111 from external damage and dust contamination, while also having high light transmittance characteristics to ensure that ambient light can normally enter the photovoltaic material layer 111 without affecting the photoelectric conversion efficiency. The base 150 can be made of metal in one piece, providing a mounting base for all components of the door lock; the photovoltaic material layer 111 is the photoelectric conversion core of the light energy collection unit 110, which can convert incident light energy into electrical energy; the light-transmitting layer 151 can be made of transparent materials such as high-transmittance tempered glass or acrylic sheet.
[0051] In some embodiments, the door lock assembly 100 further includes a light-transmitting touch sensing layer 152, located between the photovoltaic material layer 111 and the light-transmitting layer 151, for acquiring touch signals on the light-transmitting layer 151. In related technologies, the touch button area requires a perforation in the photovoltaic material layer 111, which reduces the photovoltaic light-receiving area and lowers light energy collection efficiency. In this solution, the touch sensing layer 152 adopts a fully light-transmitting design, located between the photovoltaic material layer 111 and the light-transmitting layer 151, eliminating the need for perforations in the photovoltaic material layer 111. This does not affect the full coverage of the photovoltaic material layer 111's light-receiving area, while simultaneously enabling full-panel touch sensing functionality. Users can perform auxiliary functions such as password input, emergency wake-up, and manual locking through touch operation, balancing light energy collection efficiency with the door lock's interactive functions.
[0052] See Figure 3 In some embodiments, a door lock control method is provided for any of the above-mentioned door lock components 100, and the specific steps are as follows: S101: The light energy harvesting unit 110 converts ambient light energy into electrical energy and prioritizes charging the first energy storage unit 121. This ensures that the first energy storage unit 121 always has sufficient power and can provide instantaneous operating current to the execution unit 140 at any time.
[0053] S102: When the voltage of the first energy storage unit 121 reaches the full charge threshold, excess electrical energy is charged to the second energy storage unit 122. This is used to detect the terminal voltage of the first energy storage unit 121 in real time. When the voltage reaches the preset full charge threshold, the excess electrical energy of the first energy storage unit 121 is charged into the second energy storage unit 122 through the conversion circuit. This achieves the goal of storing excess light energy converted into electrical energy in the high-energy-density second energy storage unit 122 while meeting the instantaneous discharge requirements of the first energy storage unit 121, thus realizing the long-term energy reserve of the system.
[0054] S103: The sensing unit 130 continuously monitors the presence signal of a human body within a preset range under the power supply of the light energy harvesting unit 110, and outputs a wake-up signal when a human body is detected. It is used to detect the user's approach action in real time, provide a trigger signal for contactless unlocking, and is directly powered by the light energy harvesting unit 110, without consuming the power of the energy storage unit.
[0055] S104: After receiving the wake-up signal, the execution unit 140 is woken up from the sleep state by the instantaneous operating current provided by the first energy storage unit 121. This is used to quickly wake up the execution unit 140 when the user approaches, while the static power consumption of the system can be significantly reduced in the sleep state.
[0056] S105: Execution unit 140 verifies with an external wireless terminal. It establishes an encrypted communication connection with the external wireless terminal via a short-range wireless communication protocol, transmits identity information, and completes legitimacy verification to automatically verify the user's identity without requiring any active user intervention, thus meeting the needs of seamless access.
[0057] S106: After successful verification, the execution unit 140 performs the unlocking action. This is used to output a drive control signal after successful authentication, driving the lock body mechanism to complete the unlocking action of retracting the bolt, thereby enabling unlocking before the user reaches the door and achieving seamless passage.
[0058] During the execution of the above steps, when the voltage of the first energy storage unit 121 is lower than a preset threshold, the second energy storage unit 122 replenishes the first energy storage unit 121 with electrical energy. This is used to monitor the terminal voltage of the first energy storage unit 121 in real time. When the voltage is lower than a preset minimum operating threshold, the second energy storage unit 122 replenishes the first energy storage unit 121 with electrical energy through a power conversion circuit until the voltage of the first energy storage unit 121 rises back to a safe operating range. This ensures that the voltage of the first energy storage unit 121 is always maintained above the threshold that allows for normal output of instantaneous operating current, preventing unlocking failure due to energy depletion and improving the stability and reliability of the system.
[0059] In some embodiments, a complete implementation of a door lock component 100 integrating all core optimization features is provided, as follows: The door lock assembly 100 includes a base 150, a photovoltaic material layer 111, a light-transmitting touch sensing layer 152, a light-transmitting layer 151, a low-light energy harvesting chip 112, a hybrid energy storage system 120, a radar detection module 131, and an execution unit 140. The base 150 is integrally die-cast from aluminum alloy and has a flat front wall. The photovoltaic material layer 111 uses an amorphous silicon photovoltaic thin film and fully covers the front wall of the base 150. The light-transmitting touch sensing layer 152 uses an ITO transparent touch sensing layer and is attached to the side of the photovoltaic material layer 111 facing away from the front wall. The light-transmitting layer 151 uses high-transmittance tempered glass and is attached to the side of the light-transmitting touch sensing layer 152 facing away from the photovoltaic material layer 111. All layers are bonded and fixed together using optical-grade transparent pressure-sensitive adhesive. The power output terminal of the photovoltaic material layer 111 is connected to the input terminal of the low-light energy harvesting chip 112. The low-light energy harvesting chip 112 has a starting voltage of 280mV and a starting power of 5V. W, the output of the low-light energy harvesting chip 112 is connected to the first energy storage unit 121. The first energy storage unit 121 uses a double-layer supercapacitor with a power density of 12kW / kg. The second energy storage unit 122 uses a lithium iron phosphate battery with an energy density of 160Wh / kg. The power density of the first energy storage unit 121 is more than an order of magnitude higher than that of the second energy storage unit 122, and the energy density of the second energy storage unit 122 is more than an order of magnitude higher than that of the first energy storage unit 121. The first energy storage unit 121 and the second energy storage unit 122 are connected through a bidirectional DC-DC conversion circuit. The radar detection module 131 uses a 24GHz millimeter-wave radar module with a static power consumption of 100 kWh / kg. A. The power input terminal of the radar detection module 131 is simultaneously connected to the photovoltaic material layer 111 and the first energy storage unit 121 to realize automatic switching of dual power supply. The power input terminal of the radar detection module 131 is also connected in parallel with a buffer capacitor 132, which is connected to the photovoltaic material layer 111 and charged by the photovoltaic material layer 111. The signal output terminal of the radar detection module 131 is connected to the execution unit 140. The execution unit 140 includes a low-power MCU control module 141, a Bluetooth 5.3 wireless communication module 142, and an electronic lock drive module 143 composed of a motor drive chip and a DC geared lock body motor. The power input terminals of the control module 141, the wireless communication module 142, and the electronic lock drive module 143 are all connected to the first energy storage unit 121. The control module 141 is connected to the wireless communication module 142 and the electronic lock drive module 143 respectively. After receiving the wake-up signal, the execution unit 140 completes Bluetooth verification with the external wireless terminal in 0.4 seconds. The peak instantaneous operating current provided by the first energy storage unit 121 to the execution unit 140 is 200mA.
[0060] The complete workflow of this solution is as follows: After the device is started, the preset full-charge threshold of the first energy storage unit 121 is the rated voltage value, the preset low-voltage replenishment threshold of the first energy storage unit 121 is the minimum operating voltage value, and the preset human body detection range of the radar detection module 131 is the area in front of the door 0.5-3m.
[0061] The photovoltaic material layer 111 collects light energy such as natural light and indoor lighting in the environment in real time, converts it into electrical energy through the photoelectric effect, and charges the first energy storage unit 121 first through the micro-light energy harvesting chip 112. When the control module 141 detects that the voltage of the first energy storage unit 121 reaches the full charge threshold, it controls the bidirectional DC-DC conversion circuit to charge the excess electrical energy of the first energy storage unit 121 into the second energy storage unit 122, thus completing long-term energy storage.
[0062] Under conditions of sunlight, the radar detection module 131 is directly powered by the photovoltaic material layer 111. Under conditions of no sunlight or insufficient sunlight, it automatically switches to the power supply of the first energy storage unit 121 to continuously monitor the presence of human bodies within a preset range in front of the door. When the corridor sensor light is turned on, the buffer capacitor 132 provides surge current for the radar detection module 131 at the moment of startup, supporting the rapid startup of the radar detection module 131.
[0063] When the radar detection module 131 detects the presence of a human body within a preset range, it immediately outputs a wake-up signal to the control module 141. After receiving the wake-up signal, the control module 141 is awakened from its dormant state by the instantaneous operating current provided by the first energy storage unit 121, and the Bluetooth wireless communication module 142 is started simultaneously.
[0064] The Bluetooth wireless communication module 142 quickly scans for pre-authorized external wireless terminals in the vicinity, establishes an encrypted Bluetooth communication connection, and completes identity verification within 0.4 seconds. If the identity verification is successful, the control module 141 immediately outputs an unlocking control signal to the motor drive chip. The motor drive chip drives the DC geared lock body motor to rotate, causing the bolt to retract and complete the unlocking action, thus achieving seamless passage. If the identity verification fails, or no authorized terminal is detected within 3 seconds, the control module 141 controls the execution unit 140 to switch back to the sleep state, waiting for the next wake-up signal.
[0065] Throughout the entire process, the control module 141 monitors the terminal voltage of the first energy storage unit 121 in real time. When the voltage of the first energy storage unit 121 is detected to be lower than the preset low-voltage replenishment threshold, the control module 141 starts the bidirectional DC-DC conversion circuit, and the second energy storage unit 122 replenishes the first energy storage unit 121 with electrical energy until the voltage of the first energy storage unit 121 rises back to the safe operating range, ensuring that a stable instantaneous current supply can be obtained every time it is woken up.

If the specific posture changes, the directional indications will also change accordingly.

Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the direction reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.
