Description

Technical Field

[0001] This application relates to the field of door lock technology, and more specifically, to a power generation device for door locks. Background Technology

[0002] In related technologies, some solutions attempt to use the mechanical motion of the door during opening and closing to drive a power generation device to achieve energy recovery. However, the power generation device is typically limited to the edge area of ​​the door or around the hinge rotation axis, resulting in limited installation space and difficulty in adapting to different door structures. Furthermore, it cannot simultaneously support multiple opening modes such as inward and outward opening, leading to low installation flexibility and poor versatility in practical applications. At the same time, existing solutions mostly rely on a single power generation mode, either solely on door movement or a separate manual mechanism outside the door; the two are not organically integrated, making it difficult to conveniently switch power supplies in emergencies. Utility Model Content

[0003] This application provides a power generation device for door locks, which can be adapted to different door structures and opening / closing directions, improving installation flexibility and versatility.

[0004] This application is achieved through the following technical solution: This application provides a power generation device for a door lock, including a first housing, a second housing, a lock accessory, a lever, a power generation component, a transmission mechanism, and a drive shaft. The first housing and the second housing are respectively disposed on both sides of a door body along a first direction. The lock accessory is used to lock the first housing and the second housing to the door body. The lever is rotatably connected to the first housing and extends at least partially out of the first housing, with the rotation axis of the lever perpendicular to the first direction. The power generation component and the transmission mechanism are both disposed within the first housing. The power generation component is drively connected to the lever through the transmission mechanism. The drive shaft is rotatably disposed on the first housing and the second housing around its own axis, with one end of the drive shaft extending into the second housing on the side opposite to the first housing. The drive shaft can be axially moved relative to the first housing and can switch between a first position coupled to the transmission mechanism and a second position decoupled from the transmission mechanism. The power generation device is used to generate electricity when the drive shaft rotates in the first position and when the lever rotates relative to the first housing.

[0005] In the technical solution of this application embodiment, a split design with the first and second housings respectively located on both sides of the door body, combined with a dual power input structure of a toggle block and a drive shaft, and the drive shaft being able to switch between coupling and decoupling positions along the axial direction, achieves dual-mode power generation. This overcomes the problem that the installation position of existing power generation devices is limited to the edge of the door body or around the hinge, greatly improving installation flexibility; it is compatible with multiple opening directions such as inward opening and outward opening, and adapts to different door structures.

[0006] In some possible implementations, the transmission mechanism includes a first transmission component and a second transmission component, wherein the first transmission component is drivenly connected to the toggle block, and the second transmission component is drivenly connected to the power generation component; when the drive shaft is in the first position, the drive shaft is coupled to the second transmission component, and both the second transmission component and the drive shaft are decoupled from the first transmission component; when the drive shaft is in the second position, both the second transmission component and the first transmission component are decoupled from the drive shaft, and the second transmission component is coupled to the first transmission component.

[0007] The transmission mechanism is divided into a first transmission component and a second transmission component, which are respectively connected to the toggle block and the power generation component. The coupling and decoupling states of each component are precisely controlled according to the axial position of the drive shaft. This enables seamless switching between the toggle block power generation mode and the drive shaft power generation mode. When the drive shaft generates power, the transmission path of the toggle block is cut off; when the toggle block generates power, the drive shaft is isolated to avoid power interference. The modular design allows the transmission mechanism to adapt to different power input sources, ensuring efficient and smooth power transmission. This solves the technical challenge of switching between multiple power generation modes and improves transmission reliability and energy conversion efficiency.

[0008] In some possible implementations, the first transmission assembly includes a rack movably disposed within the first housing, the rack being pulsatorically connected to the paddle; the second transmission assembly includes a first gear and a second gear, the first gear and the second gear being circumferentially fixed and both sleeved on the drive shaft, the second gear being axially fixed to the first housing and pulsatorically connected to the power generation assembly, the drive shaft moving from a second position to a first position driving the first gear to move axially relative to the first housing, thereby switching the first gear from a third position to a fourth position; in the third position, the first gear meshes with the rack, and the second gear and the first gear can rotate freely relative to the drive shaft; in the fourth position, the first gear disengages from the rack, and the second gear is circumferentially locked to the drive shaft.

[0009] The first transmission component is linked to the lever via a rack and pinion. The second transmission component has two gears circumferentially fixed to the drive shaft, while the first gear can move axially to switch engagement states. The transmission logic for the two power generation modes is clearly defined: when the lever rotates, it drives power generation through the meshing of the rack and pinion with the first gear; when the drive shaft rotates, it directly generates power by circumferentially locking with the second gear. The gear and rack engagement ensures precise power transmission, and the design of the double gears' idling and locking avoids energy loss. The switching process is stable and smooth, enabling the device to generate power efficiently in different operating scenarios and simplifying the complexity of the transmission mechanism.

[0010] In some possible implementations, the power generation device includes a first reset member disposed between the second gear and the first gear, the first reset member being used to drive the first gear to switch from the fourth position to the third position.

[0011] The first reset element is located between the second gear and the first gear, and is used to drive the first gear to reset from the fourth position to the third position. This ensures that when the drive shaft switches from the first position back to the second position, the first gear can automatically and reliably re-engage with the rack, ensuring that the block power generation mode is always available; it avoids transmission jamming or mode switching obstacles caused by gear reset failure, improves the smoothness of switching between the two power generation modes, reduces the risk of mechanical failure, and extends the service life and operational stability of the device.

[0012] In some possible implementations, the second gear includes a wheel body and a bushing, the wheel body being axially connected to the bushing, and the outer peripheral surface of the bushing being provided with a limiting boss; the first gear has a first limiting groove, and the limiting boss is slidably accommodated in the first limiting groove; The drive shaft is provided with a limiting part, and the first gear is located between the limiting part and the wheel body. The limiting part is provided with a second limiting groove. When the drive shaft is in the first position, the limiting boss is accommodated in the second limiting groove. When the drive shaft is in the second position, the limiting boss exits the second limiting groove. When the drive shaft moves from the second position to the first position, it can drive the first gear to switch from the third position to the fourth position through the limiting part.

[0013] The second gear, with its axial connection to the bushing, features a limiting boss that engages with the first limiting groove of the first gear and the second limiting groove of the drive shaft limiting part. Through precise meshing of the mechanical structure, accurate control of the axial position and circumferential transmission relationship of the first gear is achieved, ensuring a seamless and uninterrupted switching process. Axial movement of the drive shaft directly drives the transmission mode switching, making operation intuitive and convenient. This solves the problem of accurately controlling the transmission relationship between the first gear, rack, and drive shaft, resulting in a more compact structure and more reliable operation.

[0014] In some possible implementations, the power generation device includes a rocker arm rotatably connected to one end of the drive shaft extending out of the second housing. The axis of rotation of the rocker arm relative to the drive shaft is perpendicular to the axis of rotation of the drive shaft relative to the second housing. The second housing is provided with a third limiting groove, and when the drive shaft is in the second position, the rocker arm can be accommodated within the third limiting groove when rotating relative to the drive shaft.

[0015] The rocker arm is rotatably connected to the extended end of the drive shaft, with the axis of rotation perpendicular to the drive shaft axis. The second housing has a third limiting groove for storing the rocker arm. When the rocker arm is extended, it forms a force-saving lever, reducing the difficulty of manually rotating the drive shaft to generate electricity and improving the user experience. When stored, it can be embedded in the third limiting groove, flush with the surface of the second housing, avoiding misoperation or aesthetic problems caused by protrusion. It balances the practicality of manual power generation with the integrity of the door lock, making the device feature-rich while maintaining simplicity and convenience.

[0016] In some possible implementations, the transmission mechanism includes a movable member, a buffer member, a rack, and a gear. The movable member and the rack are both movably disposed within the first housing along a second direction. The buffer member is connected between the movable member and the rack along the second direction. The gear is rotatably disposed within the first housing. The movable member is drivenly connected to the toggle block, and the gear is drivenly connected to the power generation component. The first direction, the second direction, and the rotation axis of the toggle block are perpendicular to each other.

[0017] The transmission mechanism receives power from the lever via a moving part. A buffer connects the moving part and the rack, and all three move along a second direction, with the first and second directions perpendicular to the lever's rotation axis. The buffer effectively absorbs the impact force and uneven torque during lever operation, avoiding component wear caused by rigid connections and extending the transmission system's lifespan. The three-dimensional orthogonal spatial layout improves space utilization, making the transmission structure compact and power transmission smooth, ensuring stable operation of the power generation components, improving power generation efficiency and energy conversion reliability, and optimizing the connection between manual operation and power generation.

[0018] In some possible implementations, the lever is provided with a convex shaft, the movable member is provided with a transmission groove, the convex shaft is accommodated in the transmission groove, and the axis of the convex shaft is parallel to the rotation axis of the lever.

[0019] The convex shaft of the lever is accommodated within the transmission groove of the movable part, and the axis of the convex shaft is parallel to the rotation axis of the lever. This achieves precise and efficient conversion of the lever's rotational motion into the linear motion of the movable part, with a tight transmission fit and no obvious gaps. The parallel axis design reduces lateral forces and frictional losses during transmission, avoids jamming, and improves transmission efficiency. The structure is simple and reliable, easy to process and assemble, providing a stable foundation for subsequent energy transfer and ensuring the overall transmission stability and service life of the power generation device.

[0020] In some possible implementations, the lever has a first surface, a second surface, and a sidewall surface, the first surface and the second surface being arranged along the rotation direction of the lever, and the sidewall surface connecting the first surface and the second surface; the lever is provided with a hook, the hook being disposed on the sidewall surface; along the rotation direction of the lever, the distance between the hook and the first surface is greater than the distance between the hook and the second surface, and the distance between the convex shaft and the first surface is less than the distance between the convex shaft and the second surface.

[0021] The lever is divided into a first surface, a second surface, and a side wall. The lug is located on the side wall, and the distances between the lug, the convex shaft, and the two surfaces are asymmetrically designed. When operating the lug to drive the lever, the rotation angle of the lever should be as large as possible.

[0022] In some possible implementations, at least one of the first housing and the second housing is provided with a housing, the power generation device is provided with a battery, the battery is removably housed in the housing, and the power generation component is electrically connected to the battery.

[0023] The first or second housing has a receiving box to house the removable battery, which is electrically connected to the power generation component. This solves the problem of unstable power supply caused by intermittent power generation of the power generation device. The battery stores excess energy to ensure a continuous and stable power supply for the door lock's electronic equipment. The removable design allows the battery to be directly removed to power the door lock's power supply battery or directly to power the door lock's electrical components. Attached Figure Description

Detailed Implementation

[0027] To make this application clearer, specific embodiments are described below with reference to the accompanying drawings: This application provides a power generation device (hereinafter referred to as the power generation device) for a door lock. Please refer to... Figures 1 to 3 In some embodiments, the power generation device 1000 includes a first housing 110, a second housing 120, a locking attachment 200, a lever 300, a power generation component 400, a transmission mechanism 500, and a drive shaft 600. The first housing 110 and the second housing 120 are respectively disposed on both sides of the door body 2001 along a first direction; the locking attachment 200 is used to lock the first housing 110 and the second housing 120 to the door body 2001; the lever 300 is rotatably connected to the first housing 110, at least partially extending out of the first housing 110, and the rotation axis of the lever 300 is perpendicular to the first direction; the power generation component 400 and the transmission mechanism 500 are both disposed on the first housing 110. Within a housing 110, a power generation component 400 is connected to a toggle block 300 via a transmission mechanism 500. A drive shaft 600 is rotatably mounted on the first housing 110 and the second housing 120 around its own axis. One end of the drive shaft 600 extends into the second housing 120 on the side opposite to the first housing 110. The drive shaft 600 can move axially relative to the first housing 110 and can switch between a first position coupled with the transmission mechanism 500 and a second position decoupled from the transmission mechanism 500. The power generation device 1000 is used to generate electricity when the drive shaft 600 is rotating in the first position and when the toggle block 300 rotates relative to the first housing 110.

[0028] For ease of understanding, the following explains some key terms in this embodiment: The generator 1000 is designed as a device that can convert mechanical energy into electrical energy, and is mainly used in door lock systems to provide power support.

[0029] Door body 2001 refers to the door structure on which the power generation device 1000 is installed. It can be any type of door, such as an entrance door or an interior door.

[0030] The first housing 110 and the second housing 120 serve as the external structure of the power generation device 1000 and are configured to be installed on both sides of the door 2001, respectively. This split design helps to integrate the power generation device 1000 into the door 2001 of different thicknesses and provides a flexible installation method.

[0031] Lock accessory 200 refers to a connector or mechanism used to secure the first housing 110 and the second housing 120 to the door body 2001. This lock accessory 200 ensures that the power generation device 1000 is securely installed on the door body 2001.

[0032] The lever 300 is an input component of the power generation device 1000 and is rotatably connected to the first housing 110. The lever 300 extends at least partially out of the first housing 110 for external operation. The axis of rotation of the lever 300 is designed to be perpendicular to a first direction, which allows the rotation of the lever 300 to effectively drive the internal transmission mechanism.

[0033] The power generation component 400 is the core component of the power generation device 1000, responsible for converting received mechanical energy into electrical energy. This power generation component 400 typically includes a generator, rectifier circuits, etc., to generate and output stable electrical energy.

[0034] The transmission mechanism 500 is a mechanical transmission system that connects the toggle block 300, the drive shaft 600, and the power generation component 400. The transmission mechanism 500 is responsible for converting the rotation or movement of the toggle block 300 or the drive shaft 600 into the input motion required by the power generation component 400, thereby driving the power generation component 400 to generate electricity.

[0035] The drive shaft 600 is another input component of the power generation device 1000. The drive shaft 600 is rotatably disposed between the first housing 110 and the second housing 120 about its own axis. One end of the drive shaft 600 extends out of the second housing 120 for external operation. The drive shaft 600 also has the ability to move axially, allowing it to switch between two different operating positions, thereby selectively driving the transmission mechanism 500.

[0036] The first direction refers to the axial direction of the first housing 110 and the second housing 120 on both sides of the door body 2001, which is usually parallel to the thickness direction of the door body.

[0037] The first position refers to the working state in which the drive shaft 600 is coupled with the transmission mechanism 500 after moving axially. In the first position, the rotation of the drive shaft 600 can drive the transmission mechanism 500.

[0038] The second position refers to the working state in which the drive shaft 600 is decoupled from the transmission mechanism 500 after moving axially. In the second position, the rotation of the drive shaft 600 will not drive the transmission mechanism 500.

[0039] The first housing 110 and the second housing 120 are designed to be disposed on opposite sides of the door body 2001 along a first direction. As one implementation, the first housing 110 and the second housing 120 can be fixed to the door body 2001 by means of bolts, snap-fit ​​connections, or welding. For example, the first housing 110 can be a main body internally housing the power generation component 400 and the transmission mechanism 500, while the second housing 120 can be an auxiliary housing for supporting the drive shaft 600 and providing an external operating interface. In another implementation, the first housing 110 and the second housing 120 can be connected to the door body 2001 respectively via their respective mounting bases to accommodate different door body 2001 structures.

[0040] Locking accessory 200 is used to lock the first housing 110 and the second housing 120 to the door body 2001. Locking accessory 200 can be a simple set of screws that secure the two housings by passing through the door body 2001. Alternatively, locking accessory 200 can be a lock cylinder structure with anti-theft function, providing door locking functionality while securing the housings. In some embodiments, locking accessory 200 may include multiple fixing points to enhance the stability of the power generation device 1000 on the door body 2001.

[0041] The lever 300 is designed to be rotatably connected to the first housing 110 and at least partially extend beyond the first housing 110. The axis of rotation of the lever 300 is configured to be perpendicular to a first direction. For example, the lever 300 may be a lever or a rocker arm, with one end extending beyond the door body 2001. When the door body 2001 is opened or closed, the lever 300 rotates due to being pushed or pulled by the door frame 2002 or other components on the door body 2001. The rotational motion of the lever 300 is used to drive the internal transmission mechanism 500.

[0042] Both the power generation component 400 and the transmission mechanism 500 are housed within the first housing 110. The power generation component 400 can be a miniature generator, such as a DC generator or an AC generator, which converts mechanical energy into electrical energy through electromagnetic induction. The transmission mechanism 500 can consist of a series of gears, belts, or chains, used to transmit the motion of the lever 300 or the drive shaft 600 to the power generation component 400. For example, the transmission mechanism 500 can be a simple gear train that converts the low-speed, high-torque rotation of the lever 300 into the high-speed, low-torque rotation required by the power generation component 400.

[0043] The power generation component 400 is connected to the toggle block 300 via a transmission mechanism 500. Specifically, when the toggle block 300 rotates, its movement is received by the transmission mechanism 500 and transmitted to the power generation component 400, thereby driving the power generation component 400 to generate electricity. For example, a gear can be installed on the rotating shaft of the toggle block 300, which meshes with the input gear of the transmission mechanism 500, thereby driving the entire transmission mechanism 500 to operate.

[0044] A drive shaft 600 is rotatably mounted on the first housing 110 and the second housing 120 about its own axis. One end of the drive shaft 600 extends into the second housing 120 on the side opposite to the first housing 110. Alternatively, the drive shaft 600 can be a solid shaft passing through both the first housing 110 and the second housing 120, with both ends supported by bearings to ensure smooth rotation. The end extending out of the second housing 120 can be connected to an external handle or knob for user operation.

[0045] The drive shaft 600 is axially movable relative to the first housing 110, capable of switching between a first position coupled to the transmission mechanism 500 and a second position decoupled from the transmission mechanism 500. For example, a cam or pin can be provided on the drive shaft 600, which contacts or separates from a corresponding structure on the transmission mechanism 500 when the drive shaft 600 moves axially, thereby achieving coupling or decoupling. In the first position, rotation of the drive shaft 600 drives the transmission mechanism 500. In the second position, rotation of the drive shaft 600 does not drive the transmission mechanism 500. This switching function allows the power generation device 1000 to select different power generation modes as needed.

[0046] Therefore, the power generation device 1000 generates electricity when the drive shaft 600 is rotating in the first position and when the lever 300 rotates relative to the first housing 110. This means that the power generation device 1000 provides two independent power generation pathways. For example, when the user rotates the drive shaft 600 via an external handle, if the drive shaft 600 is in the first position, the power generation component 400 is driven to generate electricity. Simultaneously, when the user operates the lever 300 of the door lock, regardless of the position of the drive shaft 600, the rotation of the lever 300 can also drive the power generation component 400 to generate electricity. This dual-generation mechanism improves the flexibility and efficiency of power generation.

[0047] This power generation device 1000 achieves flexible installation location by separately positioning the first housing 110 and the second housing 120 on both sides of the door body 2001 and fixing them with the lock attachment 200, no longer limited to the door edge or near the hinge. The operating ends of the toggle block 300 and the drive shaft 600 are located on both sides of the door body 2001 along the thickness direction, that is, one operating end of the toggle block 300 and the other operating end of the drive shaft 600 are on the inside of the door and the other is on the outside of the door, which can select the installation position according to different opening and closing directions of the door body 2001, improving the compatibility with various door body 2001 operations.

[0048] The following example will provide a more detailed explanation of the above technical solution: Traditional door lock power generation solutions may require installing the power generator near the door edge or hinges, which limits the installation location and may not be compatible with all opening and closing directions. To solve this technical problem, the power generation device 1000 of this embodiment is applied to the door lock.

[0049] Specifically, the power generation device 1000 includes a first housing 110 and a second housing 120. The first housing 110 is installed on the inner side of the door body 2001, while the second housing 120 is installed on the outer side of the door body 2001, and the two are separated along the thickness direction (i.e., the first direction) of the door body 2001. A locking accessory 200, such as a set of long bolts, passes through the door body 2001 to securely fasten the first housing 110 and the second housing 120 to the door body 2001.

[0050] Inside the door body 2001, the user can operate the door lock by rotating a toggle 300. This toggle 300 is rotatably connected to the first housing 110, with a portion extending out of the first housing 110 for easy gripping and rotation. The rotation axis of the toggle 300 is designed to be perpendicular to the thickness direction of the door body 2001. When the user rotates the toggle 300, for example, to open or lock the door, the rotational movement of the toggle 300 is transmitted to the transmission mechanism 500 located within the first housing 110.

[0051] After receiving the movement of the toggle 300, the transmission mechanism 500 converts it into input movement suitable for the power generation component 400. For example, the transmission mechanism 500 may include a gear connected to the toggle 300, which in turn drives the rotor of the power generation component 400 through a series of intermediate gears. The power generation component 400 then begins to generate electricity, storing the generated electrical energy or directly supplying it to the door lock system.

[0052] Meanwhile, a drive shaft 600 is provided on the outside of the door body 2001. This drive shaft 600 passes through the first housing 110 and the second housing 120, and is rotatable about its own axis. One end of the drive shaft 600 extends out of the second housing 120, for example, and is connected to an external handle. The user or external personnel can operate the drive shaft 600 by turning this external handle.

[0053] The drive shaft 600 also has a unique function: it can switch between two axial positions: a first position and a second position. When the drive shaft 600 is in the first position, it is coupled to the transmission mechanism 500. This means that turning the external handle will cause the drive shaft 600 to rotate, which will be received by the transmission mechanism 500 and drive the power generation component 400 to generate electricity. When the drive shaft 600 is in the second position, it is decoupled from the transmission mechanism 500; turning the external handle will not cause the drive shaft 600 to rotate. This switching mechanism can be achieved through an axial movement mechanism on the drive shaft 600, such as a push-pull button or a rotary locking mechanism.

[0054] Therefore, the power generation device 1000 provides two independent power generation pathways: one is when the user rotates the toggle 300 from the inside of the door; the other is when the user or an external person rotates the drive shaft 600 from the outside of the door (with the drive shaft 600 in the first position). These two power generation methods can be performed independently or simultaneously, thus ensuring that the door lock system can continuously obtain electrical energy. For example, when the user opens the door from the inside, the toggle 300 rotates to generate electricity; when the user opens the door from the outside using the external handle, if the drive shaft 600 is in the first position, the drive shaft 600 rotates to generate electricity. This design allows the power generation device 1000 to fully utilize the daily operation of the door lock to collect energy, improving the efficiency and reliability of energy collection.

[0055] To accommodate different opening and closing directions, the first housing 110 can be installed on the outside of the door and the second housing 120 can be installed on the inside of the door; this application does not limit this.

[0056] According to some embodiments of this application, such as Figure 1 , Figures 3 to 5The transmission mechanism 500 includes a first transmission component 510 and a second transmission component 520. The first transmission component 510 is drive-connected to the toggle block 300, and the second transmission component 520 is drive-connected to the power generation component 400. When the drive shaft 600 is in the first position, the drive shaft 600 is coupled to the second transmission component 520, while both the second transmission component 520 and the drive shaft 600 are decoupled from the first transmission component 510. When the drive shaft 600 is in the second position, both the second transmission component 520 and the first transmission component 510 are decoupled from the drive shaft 600, while the second transmission component 520 is coupled to the first transmission component 510.

[0057] The first transmission assembly 510 and the second transmission assembly 520 are further refinements of the transmission mechanism 500, each undertaking a different transmission function. The first transmission assembly 510 is primarily responsible for receiving the motion of the lever 300 and converting it into a form suitable for subsequent transmission. For example, the first transmission assembly 510 can be composed of gears, racks, linkage mechanisms, or cam mechanisms, used to convert the rotational motion of the lever 300 into linear reciprocating motion or another type of rotational motion. The second transmission assembly 520 is primarily responsible for transmitting the received motion to the generator assembly 400 and coupling or decoupling it from the drive shaft 600. The second transmission assembly 520 can be composed of gear sets, pulley sets, or sprocket sets, and its design allows for speed or torque variation to meet the optimal operating speed or torque requirements of the generator assembly 400. This modular design allows the transmission mechanism 500 to more flexibly adapt to different power input sources.

[0058] When the drive shaft 600 is in the first position, it is coupled to the second transmission assembly 520. This state defines the transmission path when the drive shaft 600 acts as the primary power input source. Coupling can be achieved in various ways. For example, the drive shaft 600 can be provided with splines, keyways, or toothed structures. When the drive shaft 600 moves axially to the first position, these structures engage with corresponding structures on the second transmission assembly 520, such as spline holes, keyholes, or gears, thereby achieving circumferential power transmission. Simultaneously, both the second transmission assembly 520 and the drive shaft 600 are decoupled from the first transmission assembly 510. This means that the transmission path of the toggle block 300 is broken, ensuring that the rotational motion of the drive shaft 600 can be efficiently and without interference transmitted to the power generation assembly 400. Decoupling can be achieved through gaps, separation, or disengagement between components. For example, there may be sufficient axial or radial clearance between relevant components on the first transmission assembly 510 and the drive shaft 600 or the second transmission assembly 520 to prevent power transmission.

[0059] When the drive shaft 600 is in the second position, both the second transmission assembly 520 and the first transmission assembly 510 are decoupled from the drive shaft 600. This state defines the transmission path when the toggle 300 acts as the primary power input source. When the drive shaft 600 moves axially to the second position, the coupling structure between the drive shaft 600 and the second transmission assembly 520 separates, thereby cutting off the power input from the drive shaft 600 to the power generation assembly 400. Simultaneously, the second transmission assembly 520 couples with the first transmission assembly 510, meaning that the movement of the toggle 300 can be transmitted to the power generation assembly 400 through the first transmission assembly 510 and the second transmission assembly 520. This coupling can also be achieved through gear meshing, friction clutches, or other mechanical connections, ensuring that the movement of the toggle 300 can effectively drive the power generation assembly 400 to generate electricity.

[0060] By dividing the transmission mechanism 500 into a first transmission component 510 and a second transmission component 520, and precisely controlling the coupling and decoupling states between the components according to the axial position of the drive shaft 600, flexible switching between two different power generation modes is achieved. When the drive shaft 600 is in the first position, its rotational motion is directly transmitted to the power generation component 400 through the second transmission component 520. At this time, the first transmission component 510 is decoupled, ensuring the independence and efficiency of the power generation mode of the drive shaft 600. When the drive shaft 600 is in the second position, the drive shaft 600 is decoupled from the second transmission component 520, while the first transmission component 510 is coupled to the second transmission component 520, thereby transmitting the rotational motion of the toggle block 300 to the power generation component 400. This design allows the power generation device 1000 to selectively utilize the movement of the drive shaft 600 or the toggle block 300 to generate electricity according to actual needs, effectively solving the technical problem of switching between multiple power generation modes and avoiding mutual interference between different transmission paths, ensuring smooth and reliable power transmission.

[0061] According to some embodiments of this application, such as Figures 3 to 6 As shown, the first transmission assembly 510 includes a rack 550, which is movably disposed within the first housing 110 and is drively connected to the lever 300. The rack 550 is a mechanical element that converts rotational motion into linear motion, or vice versa. The rack 550 is typically a toothed straight rod that can mesh with gears. In this application, the rack 550 is movably disposed within the first housing 110, and can convert the rotation of the lever 300 into linear motion, thereby driving the subsequent transmission mechanism. The rack 550 can be made of metal materials such as steel or aluminum alloy, or high-strength engineering plastics, to meet different strength and wear resistance requirements. The movement of the rack 550 can be linearly guided by guide rails or grooves.

[0062] The second transmission assembly 520 includes a first gear 521 and a second gear 522. The first gear 521 and the second gear 522 are circumferentially fixed and both are sleeved on the drive shaft 600. The second gear 522 is axially fixed to the first housing 110 and is drive-connected to the power generation assembly 400. Moving the drive shaft 600 from a second position to a first position can drive the first gear 521 to move axially relative to the first housing 110, thereby switching the first gear 521 from a third position to a fourth position. The first gear 521 and the second gear 522 are mechanical elements used to transmit rotational motion and torque. Their circumferential fixation and sleeved on the drive shaft 600 mean they can rotate together on the drive shaft 600, but may allow axial relative movement or relative freewheeling with respect to the drive shaft 600. The first gear 521 is mainly used to mesh with the rack 550, converting the linear motion generated by the paddle 300 back into rotational motion. The second gear 522 is drive-connected to the power generation assembly 400, responsible for transmitting mechanical energy to the power generation assembly 400. These two gears can be spur gears, helical gears, or bevel gears, and the material can be metal or engineering plastic, depending on the transmission ratio, load, and noise requirements. Axial movement of the drive shaft 600 can be triggered externally, such as by pushing or pulling the drive shaft 600. When the drive shaft 600 moves, its internal structure engages with the first gear 521, causing the first gear 521 to move along the axial direction of the drive shaft 600. This movement switches the first gear 521 from one preset axial position (third position) to another preset axial position (fourth position), thereby changing the meshing state of the first gear 521 with other transmission components.

[0063] When the first gear 521 is in the third position, it meshes with the rack 550, and the second gear 522 and the first gear 521 can idle relative to the drive shaft 600. This defines the first operating mode, namely the toggle block 300 power generation mode. When the first gear 521 is in the third position, it is mechanically connected to the rack 550, allowing the movement of the toggle block 300 to be transmitted to the first gear 521 via the rack 550. Simultaneously, the second gear 522 and the first gear 521 can idle relative to the drive shaft 600, meaning that the rotation of the drive shaft 600 will not affect power generation, or the power for power generation does not directly originate from the drive shaft 600, but rather from the toggle block 300. This idling can be achieved by using a one-way clutch, a sliding bearing, or a clearance fit between the gears and the drive shaft 600.

[0064] When the first gear 521 is in the fourth position, it disengages from the rack 550, and the second gear 522 is circumferentially locked to the drive shaft 600. This defines a second operating mode: the drive shaft 600 power generation mode. When the first gear 521 is in the fourth position, it is disconnected from the rack 550, thus cutting off the transmission path of the toggle block 300. At this time, the second gear 522 is circumferentially locked to the drive shaft 600, meaning that the rotation of the drive shaft 600 will directly drive the second gear 522 to rotate, thereby transmitting mechanical energy to the power generation component 400. This circumferential locking can be achieved through keyed connections, splined connections, pin connections, or friction clutches, ensuring that the rotation of the drive shaft 600 can be reliably transmitted to the second gear 522.

[0065] In this embodiment, the power generation device 1000 achieves effective switching and transmission between the two power generation modes of the lever 300 and the drive shaft 600 through a sophisticated transmission mechanism 500 design. Specifically, the first transmission component 510 in the transmission mechanism 500 includes a rack 550, which is movably disposed within the first housing 110 and is connected to the lever 300 in a transmission manner. When the lever 300 rotates, its motion is converted into linear movement of the rack 550. The second transmission component 520 consists of a first gear 521 and a second gear 522, which are circumferentially fixed and sleeved on the drive shaft 600. The second gear 522 is connected to the power generation component 400 in a transmission manner and is responsible for transmitting mechanical energy to the power generation component 400. The core of this solution lies in the axial movement of the drive shaft 600, which controls the first gear 521 to switch between the third and fourth positions, thereby realizing the conversion between the two power generation modes. When the drive shaft 600 is in the second position, the first gear 521 is positioned in the third position, at which point the first gear 521 meshes with the rack 550. This means that the rotation of the toggle block 300 drives the first gear 521 to rotate via the rack 550, which in turn drives the circumferentially fixed second gear 522 to rotate, ultimately transferring energy to the power generation component 400. In this mode, the first gear 521 and the second gear 522 can idle relative to the drive shaft 600, ensuring that the rotation of the drive shaft 600 does not interfere with the power generation process of the toggle block 300, or in other words, the rotation of the drive shaft 600 is not driven by the transmission of the toggle block 300. When the drive shaft 600 moves from the second position to the first position, it drives the first gear 521 to move axially to the fourth position. In the fourth position, the first gear 521 disengages from the rack 550, thereby cutting off the transmission path of the toggle block 300. At the same time, the second gear 522 is circumferentially locked to the drive shaft 600. This means that the rotation of the drive shaft 600 will directly drive the second gear 522 to rotate, transferring energy to the power generation component 400. In this mode, the rotation of the toggle block 300 no longer drives the power generation component 400; instead, the drive shaft 600 independently generates electricity. Through this design, the power generation device 1000 can flexibly switch between power generation modes by toggling the toggle block 300 or rotating the drive shaft 600, avoiding mutual interference between the two transmission paths and ensuring the efficiency and reliability of power generation. This mechanical switching mechanism simplifies the control logic and improves the stability and durability of the system.

[0066] In one specific implementation, the rack 550 in the first transmission assembly 510 can be designed as a metal rod with straight teeth. One end of the rack 550 is connected to a protrusion or linkage mechanism on the lever 300. When the lever 300 rotates, the protrusion or linkage mechanism pushes the rack 550 to reciprocate linearly along the guide groove inside the first housing 110. The first gear 521 and the second gear 522 in the second transmission assembly 520 can be spur gears. They are circumferentially fixed to the drive shaft 600 through keyways or splines, but the keyway of the first gear 521 can be designed as a long groove, allowing the first gear 521 to slide axially on the drive shaft 600. The second gear 522 can be axially fixed to the first housing 110 through bearings or bushings, and is connected to the input shaft of the generator assembly 400 through gear or belt drive. When the drive shaft 600 is in the second position, the first gear 521 is in the third position, and the teeth of the first gear 521 precisely mesh with the teeth of the rack 550. At this point, the second gear 522 and the first gear 521 can be coupled together to the drive shaft 600 via a one-way clutch or freewheel mechanism, allowing the drive shaft 600 to rotate independently without driving the gears, or vice versa. When the drive shaft 600 is axially pushed into the first position, a limiting ring or boss on the drive shaft 600 can push the first gear 521 axially to the fourth position. In the fourth position, the teeth of the first gear 521 are completely disengaged from the meshing range of the rack 550. Simultaneously, the second gear 522 can be circumferentially locked to the corresponding structure on the drive shaft 600 via an internal spline or pin, ensuring that the rotation of the drive shaft 600 can be directly transmitted to the second gear 522.

[0067] According to some embodiments of this application, such as Figures 3 to 6 As shown, the power generation device 1000 includes a first reset member 700, which is disposed between the second gear 522 and the first gear 521. The first reset member 700 is used to drive the first gear 521 to switch from the fourth position to the third position.

[0068] The first reset element 700 is a device capable of storing and releasing mechanical energy, used to provide restoring force under specific conditions, allowing the component to return to its initial or preset position. As one implementation, the first reset element 700 can be a helical compression spring, with its two ends abutting against the second gear 522 and the first gear 521, respectively. When the first gear 521 is pushed to the fourth position by the drive shaft 600, the spring is compressed, storing energy; when the drive shaft 600 moves away, the spring releases energy, pushing the first gear 521 back to the third position. Alternatively, the first reset element 700 can be an elastic washer or elastic ring placed between the second gear 522 and the first gear 521. When the first gear 521 is pushed away from the third position, the elastic washer is compressed, generating a restoring force. The function of the first reset element 700 is to ensure that the first gear 521 can automatically and reliably return to the third position, meshing with the rack 550, when the drive shaft 600 no longer applies axial force, thereby maintaining the availability of the transmission path for the toggle block 300 to drive the power generation component 400.

[0069] When the drive shaft 600 moves from the second position to the first position, it drives the first gear 521 axially from the third position to the fourth position. During this process, the first reset member 700, located between the second gear 522 and the first gear 521, is compressed or deformed, storing reset energy. When the drive shaft 600 completes its rotation and moves back from the first position to the second position, it no longer applies axial thrust to the first gear 521. At this time, the first reset member 700 releases its stored energy, generating an axial thrust that pushes the first gear 521 back from the fourth position to the third position along the axial direction of the drive shaft 600. In this way, the first gear 521 can automatically and reliably re-mesh with the rack 550, ensuring that the transmission path of the toggle block 300 driving the power generation component 400 is always ready, avoiding transmission failure or mode switching obstacles caused by the first gear 521 failing to reset in time. This design makes the switching between the two power generation modes smoother and more reliable, improving the overall stability of the power generation device 1000 and the user experience.

[0070] Through the above technical solution, when the drive shaft 600 moves from the first position back to the second position, the first reset member 700 can automatically and reliably drive the first gear 521 to switch from the fourth position to the third position. This ensures that the first gear 521 can re-mesh with the rack 550 in a timely manner, so that the transmission path of the toggle block 300 driving the power generation component 400 is always available. This avoids the problem of transmission mechanism jamming or poor power generation mode switching caused by the first gear 521 failing to reset in time, and significantly improves the stability and reliability of the power generation device 1000 in different operating modes.

[0071] According to some embodiments of this application, such as Figures 3 to 6 As shown, the second gear 522 includes a wheel body 5221 and a bushing 5222. The wheel body 5221 and the bushing 5222 are axially connected. The outer circumferential surface of the bushing 5222 is provided with a limiting boss 5223. The first gear 521 has a first limiting groove 5211, and the limiting boss 5223 is slidably accommodated in the first limiting groove 5211. The drive shaft 600 is provided with a limiting part 610. The first gear 521 is located between the limiting part 610 and the wheel body 5221. The limiting part 610 is provided with a second limiting groove 611. When the drive shaft 600 is in the first position, the limiting boss 5223 is accommodated in the second limiting groove 611. When the drive shaft 600 is in the second position, the limiting boss 5223 exits the second limiting groove 611. The drive shaft 600 can move from the second position to the first position and drive the first gear 521 to switch from the third position to the fourth position through the limiting part 610.

[0072] The wheel body 5221 of the second gear 522 is the main part that bears the power transmission and typically has a toothed structure for transmission connection with the power generation component 400. The wheel body 5221 can be integrally formed with the bushing 5222, or it can be axially fixedly connected by welding, threaded connection, interference fit, etc. The bushing 5222 is usually cylindrical and is sleeved on the drive shaft 600 to provide rotational support for the second gear 522. The limiting boss 5223 provided on the outer circumferential surface of the bushing 5222 is a protruding structure for axial and circumferential engagement with the first gear 521 and the drive shaft 600. There can be one or more limiting bosses 5223, and the shape of the limiting bosses 5223 can be rectangular, circular, or semi-circular, formed by processes such as milling, casting, or injection molding. The first limiting groove 5211 provided on the first gear 521 is a groove for accommodating the limiting boss 5223. The shape and size of the first limiting groove 5211 match the limiting boss 5223, allowing the limiting boss 5223 to slide axially within the first limiting groove 5211, but limiting the relative circumferential rotation of the limiting boss 5223, thereby ensuring that the first gear 521 and the second gear 522 rotate synchronously in the circumferential direction. The limiting part 610 provided on the drive shaft 600 can be a structure such as a step with an increased diameter, a keyway, or a pin hole on the drive shaft 600, or it can be an independent annular part or sleeve fixed to the drive shaft 600 by a key, pin, or thread. The second limiting groove 611 provided on the limiting part 610 is a groove for accommodating the limiting boss 5223 under specific conditions. The shape and size of the limiting part 610 match the limiting boss 5223, and it is formed by milling or wire cutting.

[0073] The solution of this application cleverly controls the axial position of the first gear 521 and its circumferential transmission relationship with the drive shaft 600 by the axial movement of the drive shaft 600. When the drive shaft 600 is in the second position, the non-groove portion of the limiting part 610 blocks the limiting boss 5223, causing the limiting boss 5223 to exit the second limiting groove 611. At this time, the limiting boss 5223 is pushed by the end face of the limiting part 610, thereby driving the first gear 521 to move axially to the third position and mesh with the rack 550. At the same time, since the limiting boss 5223 is blocked by the solid portion of the limiting part 610, the second gear 522 is in a circumferentially decoupled state from the drive shaft 600, allowing the second gear 522 to rotate freely relative to the drive shaft 600. At this time, the power generation device 1000 is in the power generation mode of the lever 300. When the lever 300 rotates, it drives the first gear 521 to rotate through the rack 550. The first gear 521 drives the second gear 522 to rotate through the first limiting groove 5211 and the limiting boss 5223, thereby driving the power generation component 400 to generate electricity.

[0074] As the drive shaft 600 moves axially from the second position to the first position, the second limiting groove 611 on the limiting part 610 gradually aligns with the limiting boss 5223. Once the drive shaft 600 reaches the first position, the limiting boss 5223 is accommodated in the second limiting groove 611. At this time, the first gear 521 moves axially to the fourth position under the action of (for example) the reset member, or due to the push of the limiting part 610, and disengages from the rack 550. Simultaneously, since the limiting boss 5223 is accommodated in the second limiting groove 611, the limiting boss 5223 cooperates with the side wall of the second limiting groove 611, so that the second gear 522 and the drive shaft 600 are circumferentially locked, and the power generation device 1000 is in the drive shaft 600 power generation mode. When the drive shaft 600 rotates, it drives the first gear 521 and the second gear 522 to rotate synchronously through the limiting part 610, the second limiting groove 611, the limiting boss 5223 and the first limiting groove 5211, thereby driving the power generation component 400 to generate electricity.

[0075] In one specific implementation, the second gear 522 may include a disc with external teeth as a wheel body 5221, and a hollow cylinder integrally formed with the wheel body 5221 as a bushing 5222. Two symmetrical rectangular bosses along the axial direction may be provided on the outer circumferential surface of the bushing 5222 as limiting bosses 5223. Two corresponding axial rectangular first limiting grooves 5211 may be provided on the inner wall of the central hole of the first gear 521 for sliding engagement with the limiting bosses 5223. The drive shaft 600 may be a cylindrical rod, and an annular limiting portion 610 is provided on the drive shaft 600, the diameter of which is larger than the other parts of the drive shaft 600. Two symmetrical axial grooves may be milled on the limiting portion 610 as second limiting grooves 611. When the drive shaft 600 moves axially into the first housing 110, the second limiting groove 611 on the limiting part 610 gradually aligns with the limiting boss 5223, causing the limiting boss 5223 to enter the second limiting groove 611, thereby achieving axial switching of the first gear 521 and circumferential locking with the drive shaft 600. Conversely, when the drive shaft 600 moves axially outward from the first housing 110, the non-groove portion of the limiting part 610 gradually pushes the limiting boss 5223 out of the second limiting groove 611, thereby achieving axial switching of the first gear 521 and circumferential decoupling from the drive shaft 600.

[0076] Through the above technical solution, by utilizing the ingenious cooperation of the limiting boss 5223 on the second gear 522, the first limiting groove 5211 on the first gear 521, the limiting part 610 on the drive shaft 600, and the second limiting groove 611 on the limiting part 610, precise control of the axial position of the first gear 521 and reliable switching of its circumferential transmission relationship with the drive shaft 600 are achieved. This integrated design simplifies the switching mechanism of the transmission mechanism 500, making its structure more compact and less prone to misalignment or jamming in actual use, thereby improving the reliability and stability of the power generation device 1000 when switching between different power generation modes. This solution directly drives the switching of transmission modes through the axial movement of the drive shaft 600, making operation more intuitive and convenient, and effectively solving the technical problem that it is difficult to accurately and reliably achieve the correct transmission relationship between the first gear 521, rack 550, and drive shaft 600 at different positions.

[0077] According to some embodiments of this application, such as Figure 4 , Figure 5 and Figure 7As shown, the power generation device 1000 includes a rocker arm 800, which is rotatably connected to one end of the drive shaft 600 extending out of the second housing 120. The axis of rotation of the rocker arm 800 relative to the drive shaft 600 is perpendicular to the axis of rotation of the drive shaft 600 relative to the second housing 120. The second housing 120 is provided with a third limiting groove 121, and when the drive shaft 600 is in the second position, the rocker arm 800 can be accommodated within the third limiting groove 121.

[0078] The rocker arm 800 is a lever mechanism for manual operation. It is designed to provide a convenient lever arm for the user to rotate the drive shaft 600, thereby driving the power generation component 400 to generate electricity. The rocker arm 800 can be a flat, foldable rod-like structure connected to the drive shaft 600 via a hinge for storage when not in use; alternatively, it can be a telescopic rod-like structure connected to the drive shaft 600 via a telescopic mechanism, pulled out when in use and retracted when not in use. The rotatable connection between the rocker arm 800 and the drive shaft 600 means that the rocker arm 800 can rotate relative to the drive shaft 600 about an axis. This connection can be achieved via a pin connection, where one end of the rocker arm 800 has a hole, and the extended end of the drive shaft 600 has a matching hole, with the pin passing through both holes to achieve the rotatable connection; or via a universal joint connection, allowing the rocker arm 800 to rotate relative to the drive shaft 600 in multiple directions. The rotation axis of the rocker arm 800 relative to the drive shaft 600 is perpendicular to the rotation axis of the drive shaft 600 relative to the second housing 120. This geometric relationship is typically for the convenience of retracting or extending the rocker arm 800, allowing it to fit snugly against the door or the second housing 120 when not in use, minimizing protrusion. The third limiting groove 121 is a recess or space provided on the second housing 120 to accommodate the rocker arm 800. The third limiting groove 121 can be a groove that matches the shape of the rocker arm 800, so that when the rocker arm 800 is retracted, its surface is flush with or slightly lower than the outer surface of the second housing 120; alternatively, the third limiting groove 121 can be an open slot, allowing the rocker arm 800 to swing and stop in a specific position. The function of the third limiting groove 121 is to provide a storage space for the rocker arm 800, ensuring it can be properly stored when not in use, preventing protrusion, misoperation, or damage.

[0079] When the drive shaft 600 is in the first position, the power generation device 1000 is coupled to the second transmission assembly 520, and the rotation of the drive shaft 600 can drive the power generation assembly 400 to generate electricity. When the drive shaft 600 is in the second position, the second transmission assembly 520 is decoupled from the drive shaft 600, and the rotation of the toggle block 300 can drive the power generation assembly 400 to generate electricity through the first transmission assembly 510 and the second transmission assembly 520. To facilitate manual rotation of the drive shaft 600 for power generation when needed, this application provides a rocker arm 800 at the end of the drive shaft 600 extending out of the second housing 120, and the rocker arm 800 is rotatably connected to the drive shaft 600. This rotatable connection allows the rocker arm 800 to be stored when not in use and unfolded when needed. Specifically, when the drive shaft 600 is in the second position, i.e., when the power generation device 1000 mainly generates electricity by rotating the lever 300, or when the drive shaft 600 is not actively used for power generation, the rocker arm 800 can rotate along its rotation axis and is accommodated in the third limiting groove 121 provided on the second housing 120. The rotation axis of the rocker arm 800 relative to the drive shaft 600 is perpendicular to the rotation axis of the drive shaft 600 relative to the second housing 120. This design allows the rocker arm 800 to be stored in a compact and non-protruding manner, for example, flat against the surface of the second housing 120. When the user needs to generate electricity by rotating the drive shaft 600, the rocker arm 800 can rotate out from the third limiting groove 121, forming a lever that is easy to grip, thus facilitating the user to apply force to rotate the drive shaft 600 and drive the power generation component 400 to work. This design ensures the convenience of manual power generation operation while also taking into account the overall appearance of the door lock and the safety of daily use.

[0080] In one specific implementation, the rocker arm 800 can be designed as a flat metal rod, with one end connected to the portion of the drive shaft 600 extending out of the second housing 120 via a pin. The axis of the pin is perpendicular to the axis of the drive shaft 600. The outer surface of the second housing 120 can be integrally formed or formed with additional components to create a third limiting groove 121 that matches the shape and size of the rocker arm 800. When the drive shaft 600 is in the second position, the user can rotate the rocker arm 800 along the pin, causing the rocker arm 800 to be smoothly embedded in the third limiting groove 121. The depth of the third limiting groove 121 allows the outer surface of the rocker arm 800 to be flush with or slightly recessed from the outer surface of the second housing 120, thus creating a smooth appearance. After the rocker arm 800 is embedded in the third limiting groove 121, it can be fixed by friction engagement, magnetic attraction, or a simple snap-fit ​​mechanism to prevent the rocker arm 800 from accidentally popping out. When it is necessary to generate electricity by rotating the drive shaft 600, the user can easily remove the joystick 800 from the third limit slot 121, rotate the joystick 800 to an angle that is easy to hold and operate, and then rotate the drive shaft 600.

[0081] According to some embodiments of this application, such as Figures 3 to 6 As shown, the transmission mechanism 500 includes a movable member 530, a buffer member 540, a rack 550, and a gear 560. The movable member 530 and the rack 550 are both movably disposed within the first housing 110 along the second direction. The buffer member 540 is connected between the movable member 530 and the rack 550 along the second direction. The gear 560 is rotatably disposed within the first housing 110. The movable member 530 is drivenly connected to the toggle block 300, and the gear 560 is drivenly connected to the power generation component 400. The first direction, the second direction, and the rotation axis of the toggle block 300 are perpendicular to each other.

[0082] The movable component 530 is an intermediate part in the transmission mechanism 500. Its main function is to receive the rotational motion of the toggle block 300 and convert it into its own linear movement. The movable component 530 can be specifically designed as a push rod, a rocker arm, or a driven component with a specific curved profile to adapt to the rotational form of the toggle block 300. For example, the movable component 530 can be a component with a slotted or protruding structure, cooperating with a corresponding structure on the toggle block 300 to achieve motion transmission.

[0083] A buffer 540 is disposed between the movable member 530 and the rack 550. The buffer 540 absorbs and mitigates the impact force that may be generated by the rotation of the paddle 300 and smooths the motion transmission process. The buffer 540 can be an elastic element, such as a coil spring, leaf spring, rubber pad, or silicone pad, or it can be a hydraulic or pneumatic damper, providing a cushioning effect through deformation or fluid resistance. The rack 550 is a linear motion component with teeth, which converts the linear motion transmitted by the movable member 530 through the buffer 540 into the rotational motion of the gear 560.

[0084] The rack 550 can be a spur rack or a helical rack, and its tooth profile matches that of the gear 560 to ensure smooth meshing and efficient transmission. The gear 560 is a rotating component in the transmission mechanism 500, meshing with the rack 550 to convert the linear motion of the rack 550 into its own rotational motion, which is then transmitted to the power generation assembly 400. The gear 560 can be a spur gear, a helical gear, or a worm gear, and the size and number of teeth of the rack 550 can be designed according to the required transmission ratio and torque. The movable element 530 and the rack 550 are movably arranged in a second direction, meaning they reciprocate along a specific straight path within the first housing 110. This linear movement ensures the accuracy and stability of motion transmission and provides space for the installation and function of the buffer 540. The transmission connection between the movable element 530 and the lever 300 means that the rotation of the lever 300 can directly or indirectly drive the movable element 530 to produce linear movement. This connection can be achieved in a variety of ways. For example, the cam structure on the lever 300 can cooperate with the follower on the movable part 530, or the linkage mechanism on the lever 300 can drive the movable part 530.

[0085] The transmission connection between gear 560 and power generation component 400 means that the rotational motion of gear 560 can drive the input shaft or rotor of power generation component 400 to rotate, thereby generating electrical energy. This connection can be achieved through direct shaft connection, gear train connection, belt drive, or chain drive, etc., to meet the speed and torque requirements of power generation component 400. The spatial layout in which the rotation axes of the first direction, the second direction, and the lever 300 are perpendicular to each other ensures that the rotational motion of lever 300 can be effectively converted into the linear motion of moving part 530 and rack 550, thereby driving the rotational motion of gear 560. For example, if the first direction is the thickness direction of the door body, and the rotation axis of lever 300 is perpendicular to the first direction (e.g., the horizontal direction), then the second direction can be a direction perpendicular to the first direction and the rotation axis of lever 300 (e.g., the vertical direction), thus forming a three-dimensional orthogonal motion conversion system, resulting in high space utilization and good transmission efficiency.

[0086] The transmission mechanism 500 of this application constructs a motion conversion system with a buffer function by introducing a movable component 530, a buffer component 540, a rack 550, and a gear 560. When the user rotates the lever 300, the rotational motion of the lever 300 drives the movable component 530 to move linearly in a second direction through a transmission connection with the movable component 530. The linear movement of the movable component 530 is transmitted to the rack 550 through the buffer component 540. In this process, the buffer component 540 can absorb the instantaneous impact force or uneven torque that may be generated when the lever 300 rotates, converting these impact forces into its own elastic deformation or damping effect, thereby smoothly transmitting the motion to the rack 550. After receiving the smooth linear motion, the rack 550 meshes with the gear 560, converting its own linear movement into the rotational motion of the gear 560. Finally, the rotational motion of the gear 560 drives the power generation component 400 to generate electricity stably through a transmission connection with the power generation component 400. This design cleverly utilizes the spatial arrangement where the first direction, the second direction, and the rotation axis of the lever 300 are perpendicular to each other, achieving efficient and smooth energy conversion from the rotation of the lever 300 to the rotation of the power generation component 400. The introduction of the buffer 540 effectively avoids impacts and wear on the transmission system caused by the uncertainty of manual operation, ensuring the long-term stable operation and efficient energy conversion of the power generation component 400.

[0087] According to some embodiments of this application, such as Figures 3 to 6 As shown, the lever 300 is provided with a convex shaft 310, and the movable part 530 is provided with a transmission groove 531. The convex shaft 310 is accommodated in the transmission groove 531, and the axis of the convex shaft 310 is parallel to the rotation axis of the lever 300.

[0088] The convex shaft 310 is a structure protruding from the surface of the lever 300. Its main function is to serve as a connection point or driving element for mechanical transmission between the lever 300 and the movable part 530. The convex shaft 310 can be integrally formed with the lever 300, for example, through casting or injection molding, to ensure structural strength and assembly accuracy; alternatively, the convex shaft 310 can be a separately manufactured component, securely fixed to the lever 300 by riveting, threaded connection, or interference fit. The cross-sectional shape of the convex shaft 310 can be designed as a circle, ellipse, or a shaped cylinder with a specific geometry, depending on the transmission requirements. The transmission groove 531 is a recess provided on the movable part 530. Its function is to accommodate and guide the movement of the convex shaft 310, thereby converting the rotational motion of the lever 300 into the linear reciprocating motion of the movable part 530, and ensuring stability and accuracy during transmission. The transmission groove 531 can be designed as a straight groove to allow the cam shaft 310 to slide linearly within it; it can also be an arc-shaped or irregularly shaped groove to achieve a specific motion trajectory or transmission ratio. The cross-sectional shape of the transmission groove 531 is usually matched with the shape of the cam shaft 310, such as a circular groove or a square groove, to reduce the fit clearance and improve transmission efficiency. To reduce frictional resistance, the wall surface of the transmission groove 531 can be surface treated, such as polishing or coating with a low-friction material. The cam shaft 310 is accommodated within the transmission groove 531, meaning that the cam shaft 310 is inserted into or placed inside the transmission groove 531 and can move relative to it, thereby establishing a mechanical connection between the lever 300 and the moving part 530, realizing the transmission of motion. A clearance fit can be used between the cam shaft 310 and the transmission groove 531 to allow a certain degree of freedom to accommodate assembly errors or small deviations in motion; a tight fit can also be used to ensure transmission accuracy and reduce impact. To prevent the cam shaft 310 from disengaging from the transmission groove 531, the opening of the transmission groove 531 can be designed to restrict the axial movement of the cam shaft 310, or limiting structures can be provided at both ends of the cam shaft 310. The axis of the cam shaft 310 is parallel to the rotation axis of the lever 300, meaning that the centerline of the cam shaft 310 and the rotation centerline of the lever 300 are spatially parallel. This parallel relationship ensures that when the lever 300 rotates, the cam shaft 310 can move within the transmission groove 531 in a stable and predictable manner, thereby achieving a smooth rotational-linear motion conversion. This helps simplify mechanism design, reduce lateral forces or torques during transmission, and improve transmission efficiency and component life. During design and manufacturing, precise positioning and machining can ensure that the installation position and orientation of the cam shaft 310 meet the parallel requirements.

[0089] By providing a convex shaft 310 on the lever 300 and a transmission groove 531 on the movable member 530, the convex shaft 310 can be accommodated within the transmission groove 531, thereby establishing a direct and reliable mechanical transmission connection between the lever 300 and the movable member 530. When the lever 300 rotates around its rotation axis due to external operation, such as turning a door handle, the convex shaft 310 fixed on the lever 300 will move along an arc trajectory. Since the convex shaft 310 is constrained within the transmission groove 531 of the movable member 530, the component of the arc motion of the lever 300 is effectively converted into the linear reciprocating motion of the movable member 530 along the second direction. The axis of the convex shaft 310 is parallel to the rotation axis of the lever 300. This design further ensures the smoothness and efficiency of the transmission process, avoiding problems such as transmission jamming, increased friction, or accelerated wear of components that may be caused by non-parallel axes. The linear motion of the movable part 530 then transmits force to the gear 560 through the buffer 540 and rack 550, ultimately driving the power generation component 400 to generate electricity. This precise mechanical coupling effectively solves the problem of converting the rotational motion of the toggle block 300 into the linear motion of the movable part 530, ensuring that the transmission mechanism 500 can stably and efficiently convert mechanical energy into electrical energy.

[0090] According to some embodiments of this application, such as Figures 3 to 6 As shown, the lever 300 has a first surface 301, a second surface 302, and a side wall surface 303. The first surface 301 and the second surface 302 are arranged along the rotation direction of the lever 300, and the side wall surface 303 connects the first surface 301 and the second surface 302. The lever 300 is provided with a hook 320, which is disposed on the side wall surface 303. Along the rotation direction of the lever 300, the distance between the hook 320 and the first surface 301 is greater than the distance between the hook 320 and the second surface 302, and the distance between the convex shaft 310 and the first surface 301 is less than the distance between the convex shaft 310 and the second surface 302.

[0091] As a key component of the door lock power generation device 1000, the design of the latch 320 directly affects the linkage effect with the transmission mechanism 500. The first surface 301 and the second surface 302 are arranged along the rotation direction of the latch 300, meaning they are two opposing main working surfaces on the outer periphery of the latch 320 when the latch 300 rotates. For example, they could be the top and bottom surfaces of the latch 300, or surfaces that are sequentially aligned in the rotation direction. The side wall 303 connects these two surfaces, forming the lateral profile of the latch 300. This clear surface division helps to accurately locate other features on the latch 300, such as the convex shaft 310 and the latch 320, thereby optimizing the fit between the latch 320 and the transmission mechanism 500, and providing a structural basis for the installation and functional realization of the latch 300 in the door lock system. For example, the first surface 301 and the second surface 302 could be two opposing planes of the latch 300, or curved surfaces with a certain curvature, while the side wall 303 could be a cylindrical surface or a polygonal side surface connecting these planes.

[0092] The lug 320 is a protruding structure located on the side wall 303 of the lever 300. The lug 320 provides an additional functional interface or limiting point for the lever 300. The lug 320 can be used to interact with other mechanical components of the door lock. For example, when the lever 300 rotates to a specific position, the lug 320 can trigger a switch, push a latch, or act as a limiting structure to prevent the lever 300 from over-rotating. By placing the lug 320 on the side wall 303, it can have a specific movement trajectory when the lever 300 rotates, thereby achieving precise linkage or limiting functions. For example, the lug 320 can be a protruding pin, a hook-like structure, or a protrusion with a specific shape.

[0093] A through hole can also be made on the ear loop 320, through which users can fix keychains, lanyards, etc., and generate electricity by directly driving the movement of the lever by operating the keychains, lanyards, and other external structures.

[0094] By optimizing the structure of the toggle block 300, the first surface 301, the second surface 302, and the side wall surface 303 are clearly defined, which provides a basis for the precise arrangement of functional components on the toggle block 300. By positioning the lug 320 close to the first surface 301, the user can operate the lug to drive the toggle block to rotate at the largest possible angle.

[0095] According to some embodiments of this application, such as Figure 3 and Figure 7As shown, at least one of the first housing 110 and the second housing 120 is provided with a receiving box 910, the power generation device 1000 is provided with a battery 920, the battery 920 is detachably housed in the receiving box 910, and the power generation component 400 is electrically connected to the battery 920.

[0096] The housing 910 is a structure for storing the battery 920, and is designed to provide a safe, secure, and easily accessible space. The housing 910 can be an integrally formed cavity with the first housing 110 or the second housing 120, closed by a cover; alternatively, the housing 910 can be a modular structure manufactured separately and fixed inside the first housing 110 or the second housing 120 by snaps, screws, or adhesive.

[0097] Battery 920 is an electrochemical energy storage device capable of storing electrical energy generated by power generation component 400 and releasing it when needed. Battery 920 can be a rechargeable lithium-ion battery, nickel-metal hydride battery, or nickel-cadmium battery, which have high energy density and cycle life, suitable for repeated charging and discharging; alternatively, it can be a non-rechargeable disposable battery, such as an alkaline battery or a carbon-zinc battery, suitable for scenarios with low maintenance requirements.

[0098] The battery 920 is detachably housed within the housing 910, designed to ensure easy installation, replacement, or maintenance. The housing 910 can be designed with snap-fit, slotted, or screw-fixed mechanisms to allow easy insertion or removal of the battery 920; alternatively, it can be connected via spring contacts or flexible wires to ensure that electrical connections are not damaged during battery removal. The power generation assembly 400 is electrically connected to the battery 920, serving to transfer the electrical energy generated by the power generation assembly 400 to the battery 920 for storage and to allow the battery 920 to power other electronic components of the door lock. This electrical connection can be implemented using wires, flexible circuit boards, or integrated circuits to ensure the stability and efficiency of power transmission; simultaneously, the connection path can include a charging management module to control charging current and voltage, protect the battery 920 from overcharging or over-discharging, and optimize charging efficiency.

[0099] By integrating a housing 910 and a battery 920 into the power generation device 1000, and electrically connecting the power generation component 400 to the battery 920, efficient storage and management of electrical energy are achieved. When the toggle 300 rotates or the drive shaft 600 rotates, the power generation component 400 generates electrical energy. This electrical energy is transferred to the battery 920 via an electrical connection, where the battery 920 stores this intermittently generated energy. When the electronic components of the door lock require power, the battery 920 can be removed to charge the door lock's main battery or directly provide temporary power to the internal mechanisms of the door lock, ensuring continuous operation of the door lock. The housing 910 provides physical protection and a secure space for the battery 920, while its removable design facilitates the installation and replacement of the battery 920. This configuration enables the power generation device 1000 not only to generate electricity but also to effectively manage and utilize the generated electrical energy, thereby overcoming the power instability problem caused by intermittent power generation and providing a reliable self-powered solution for the door lock.

[0100] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
