Description

Technical Field

[0001] This invention relates to the field of lock technology, and more particularly to a self-generating lock. Background Technology

[0002] Compared to mechanical locks, electronic locks do not require keys to unlock, eliminating the worries of forgetting keys or having them copied. Some electronic locks also offer remote unlocking and temporary authorization functions, making them more intelligent, convenient, and flexible to use. However, electronic locks rely on electricity and have some potential drawbacks, such as the need for regular charging or battery replacement, which is time-consuming and laborious; furthermore, discarded batteries can negatively impact the environment.

[0003] Self-generating locks do not require batteries; they rely on their own power generation to function as electronic locks, eliminating the hassle of periodic charging and battery replacement. However, most existing self-generating locks are structurally complex and have relatively low energy conversion efficiency. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by the present invention is to propose a self-generating lock with simple and compact structure and high power conversion efficiency.

[0005] The technical solution adopted by this invention to solve its technical problem is to propose a self-generating lock, comprising:

[0006] Lock case;

[0007] A locking element is movably disposed in the lock housing, and the locking element is configured to move between a locked position and an unlocked position to realize the locking and unlocking of the lock;

[0008] A circuit board is disposed in the lock housing, and the circuit board is provided with control circuitry.

[0009] A power generation module, disposed in the lock housing, includes an actuation structure and a generator. The generator is electrically connected to the control circuit, and an input gear is provided on the shaft of the generator. The actuation structure includes an output gear, which directly meshes with the input gear for transmission or indirectly meshes with it through at least one transmission component.

[0010] A clutch, disposed in the lock housing and electrically connected to the control circuit, is configured to lock the locking member in the locked position or unlock it from the locking member;

[0011] When the actuation structure is driven to unlock, the output gear rotates, driving the input gear to rotate, and the generator converts the mechanical energy input by the input gear into electrical energy.

[0012] Furthermore, the actuation structure includes a sliding plate, which is slidably disposed in the lock housing, and a rack is disposed on the sliding plate, the rack meshing with the output gear;

[0013] An elastic element is provided between the sliding plate and the lock housing. When an external force is applied to the actuation structure to perform the unlocking action, the sliding plate slides and drives the output gear to rotate through the rack, causing the elastic element to undergo elastic deformation.

[0014] Furthermore, after the external force acting on the actuation structure is removed, the elastic force of the elastic element drives the slide plate to slide in the opposite direction. The slide plate drives the output gear to rotate in the opposite direction through the rack, and the input gear rotates in the opposite direction. The generator converts the mechanical energy of the input gear into electrical energy.

[0015] Furthermore, the elastic element is configured as a tension spring, one end of which is connected to the slide plate, and the other end of which is connected to the lock housing;

[0016] Two tension springs are symmetrically arranged on the skateboard. When the external force is applied to the actuation structure to perform the unlocking action, the two tension springs undergo elastic deformation and accumulate elastic potential energy. After the external force is removed, the elastic potential energy of the two tension springs is converted into the kinetic energy of the input gear, and then converted into electrical energy through the generator.

[0017] Furthermore, the direction in which the tension spring is positioned forms an angle with the sliding direction of the slide plate, the angle being between 10 and 30 degrees.

[0018] Furthermore, the actuation structure also includes a handle, and the lock housing is provided with a handle compartment, in which the handle is rotatably mounted;

[0019] The handle extends into a lever arm on the side of the skateboard, and the lever arm moves against the skateboard.

[0020] Furthermore, the transmission component is configured as a transmission gear set;

[0021] A transmission gear set is provided between the output gear and the input gear, and the transmission gear set includes a first gear and a second gear arranged coaxially, wherein the first gear has fewer teeth than the second gear; the first gear meshes with the output gear, and the second gear meshes with the input gear; or...

[0022] Two sets of transmission gears are provided between the input gear and the output gear; one set of transmission gears includes a first gear and a second gear arranged coaxially, with the first gear having fewer teeth than the second gear; the other set of transmission gears includes a third gear and a fourth gear arranged coaxially, with the third gear having fewer teeth than the fourth gear; the output gear meshes with the first gear, the second gear meshes with the third gear, and the fourth gear meshes with the input gear; or...

[0023] At least three sets of transmission gears are provided between the input gear and the output gear.

[0024] Furthermore, the locking element is configured as a latch, which is retractably and movably disposed on the lock housing;

[0025] The clutch includes a motor and a gearbox. The motor is electrically connected to the control circuit and to the gearbox for driving the gearbox. The gearbox has an output arm and a locking block is provided on the output arm.

[0026] The motor can drive the output arm to extend and retract, so that the lock block locks onto or unlocks from the latch.

[0027] Furthermore, the slide plate is provided with at least two guide grooves along its sliding direction, and the lock housing is provided with guide protrusions that correspond one-to-one with the guide grooves, the guide protrusions extending into the guide grooves.

[0028] Furthermore, it also includes an IC card antenna board, which is disposed in the lock housing and is electrically connected to the control circuit;

[0029] The circuit board is equipped with a capacitor, and the electrical energy converted by the generator can be stored in the capacitor.

[0030] Compared with the prior art, the present invention has at least the following beneficial effects:

[0031] In this invention, a power generation module is provided in the lock. The power generation module includes an actuation structure and a generator. The output gear in the actuation structure meshes directly or indirectly with the input gear on the generator shaft. When the actuation structure is driven to unlock, the output gear rotates, driving the input gear on the generator shaft to rotate. The generator converts the mechanical energy (kinetic energy) of the input gear into electrical energy. This electrical energy is supplied to the circuit board and can power the clutch and IC card antenna board in the lock, realizing the self-generating function without the need for an additional battery. The overall structure is simple and compact.

[0032] In this invention, the actuation structure includes a sliding plate, which meshes with an output gear via a rack. An elastic element is provided between the sliding plate and the lock housing. When an external force is applied to the actuation structure to perform the unlocking action, the sliding plate slides and drives the output gear to rotate via the rack, thereby causing the input gear to rotate. The generator converts the mechanical energy of the input gear into electrical energy. That is, the sliding of the sliding plate can be converted into the rotation of the output gear, thereby driving the input gear to rotate, so as to generate electricity.

[0033] After the external force acting on the actuation structure is removed, the elastic force of the elastic element drives the slide plate to slide in the opposite direction. The slide plate drives the output gear to rotate in the opposite direction through the rack, which in turn drives the input gear to rotate in the opposite direction. The generator converts the mechanical energy of the input gear into electrical energy. That is, whether it is during the process of driving the actuation structure to unlock or during the process of the elastic element driving the actuation structure to reset after the external force is removed, the input gear will be driven to rotate, and the generator will generate electricity, resulting in high energy conversion efficiency. Furthermore, two elastic elements (i.e., tension springs) are symmetrically arranged on the slide plate. When the external force is applied to the actuation structure to unlock, the two tension springs undergo elastic deformation, accumulating elastic potential energy. After the external force is removed, the elastic potential energy accumulated by the two tension springs is converted into the kinetic energy of the input gear, and then converted into electrical energy by the generator. That is, during reset, the two tension springs overcome the load of the generator to generate electricity, ensuring a high energy conversion rate of the power generation module in the lock.

[0034] In this invention, by selectively setting one, two, or at least three transmission gear sets between the input and output gears, the transmission ratio between the output and input gears can be effectively increased. During the unlocking or resetting process, the small-range rotation of the output gear (less than one rotation) can make the input gear rotate multiple times, thereby effectively ensuring the power generation efficiency. In other words, the setting of the transmission gear set can effectively improve the power generation efficiency of the power generation module in the lock. Attached Figure Description

[0051] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0052] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0056] like Figures 1-9 As shown, the self-generating lock in this embodiment mainly includes:

[0057] Lock case 1;

[0058] Locking member 2 is movably disposed on the lock housing 1. The locking member 2 is configured to move between the locked position and the unlocked position to realize the locking and unlocking of the lock.

[0059] In this embodiment, the locking element 2 can be, but is not limited to, a locking tongue, and can also be, in the form of a locking plate, etc., which will not be described in detail here;

[0060] Circuit board 3 is disposed in the lock housing 1, and the circuit board 3 is provided with control circuitry.

[0061] The power generation module 4, disposed in the lock housing 1, includes an actuation structure 40 and a generator 41. Power is input from the actuation structure 40. The generator 41 is electrically connected to the control circuit, and an input gear 410 is provided on the shaft of the generator 41, through which kinetic energy is input to the generator 41. The actuation structure 40 includes an output gear 401, through which the power of the actuation structure 40 is output.

[0062] In one embodiment, the output gear 401 directly meshes with the input gear 410, meaning there are no other transmission components between the input gear 410 and the output gear 401. Alternatively, the output gear 401 and the input gear 410 are indirectly meshed through at least one transmission component, meaning there are other transmission components between the input gear 410 and the output gear 401, and the input gear 410 and the output gear 401 are indirectly meshed.

[0063] The clutch 5 is disposed in the lock housing 1 and electrically connected to the control circuit. The clutch 5 is configured to lock the locking member 2 in the locked position or unlock it from the locking member 2. The clutch 5 can ensure the structural stability of the locking member 2 when locked.

[0064] When the actuation structure 40 is driven to unlock, the output gear 401 rotates, driving the input gear 410 to rotate, and the generator 41 converts the mechanical energy input by the input gear 410 into electrical energy.

[0065] In actual use, the lock in this embodiment is equipped with a power generation module 4, which includes an actuation structure 40 and a generator 41. The output gear 401 in the actuation structure 40 meshes directly or indirectly with the input gear 410 on the shaft of the generator 41. When the actuation structure 40 is driven to unlock, the output gear 401 rotates, driving the input gear 410 on the shaft of the generator 41 to rotate. The generator 41 converts the mechanical energy (kinetic energy) of the input gear 410 into electrical energy. This electrical energy is supplied to the circuit board 3, which can supply power to electrical components such as the clutch 5 and the IC card antenna board 6 in the lock, realizing the self-generating function without the need for an additional battery. The overall structure is simple and compact.

[0066] Specifically, in this embodiment, the actuation structure 40 includes a sliding plate 402, which is slidably disposed in the lock housing 1. A rack 402A is disposed on the sliding plate 402, and the rack 402A meshes with the output gear 401. The sliding of the sliding plate 402 can be converted into the rotation of the output gear 401 through the engagement of the rack 402A and the output gear 401. An elastic element 403 is provided between the sliding plate 402 and the lock housing 1. Specifically, in this embodiment, the output gear 401 includes a coaxially arranged driving wheel 401A and a driven wheel 401B. Dividing it into a coaxially arranged driving wheel 401A and driven wheel 401B facilitates the engagement of the output gear 401 with other components in the lock, utilizing the space in the thickness direction of the lock to ensure a compact lock structure.

[0067] Furthermore, the output gear 401 is configured as a separate driving gear 401A and driven gear 401B, with the driven gear 401B fixedly connected to the driving gear 401A for easy torque transmission. This separate configuration of the output gear 401 facilitates manufacturing and processing. During operation, the driving gear 401A directly meshes with the rack 402A on the slide plate 402, driving the driven gear 401B to rotate. The driven gear 401B then meshes with the gears in the transmission gear set 42, transmitting the power of the output gear 401 to the input gear 410 via the transmission gear set 42, thus facilitating power generation by the generator 41.

[0068] In actual use, when an external force is applied to the actuation structure 40 to perform the unlocking action, the slide plate 402 slides and drives the output gear 401 to rotate through the rack 402A, and the elastic element 403 undergoes elastic deformation.

[0069] In this embodiment, the actuation structure 40 includes a sliding plate 402, which meshes with the output gear 401 via a rack 402A. An elastic element 403 is provided between the sliding plate 402 and the lock housing 1. When an external force is applied to the actuation structure 40 to perform the unlocking action, the sliding plate 402 slides and drives the output gear 401 to rotate via the rack 402A, thereby causing the input gear 410 to rotate. The generator 41 converts the mechanical energy of the input gear 410 into electrical energy. That is, the sliding of the sliding plate 402 can be converted into the rotation of the output gear 401, thereby driving the input gear 410 to rotate, so as to generate electricity.

[0070] Furthermore, when the external force applied to the actuating structure 40 is removed, the elastic force of the elastic element 403 drives the sliding plate 402 to slide in the opposite direction. Understandably, this reverse sliding means that the direction of sliding of the sliding plate 402 is opposite to the direction in which the external force acts on the actuating structure 40 to perform the unlocking action. Also, the sliding plate 402 drives the output gear 401 to rotate in the opposite direction via the rack 402A. Understandably, this reverse rotation means that the direction of rotation of the output gear 401 is opposite to the direction of rotation of the output gear 401 when the external force acts on the actuating structure 40 to perform the unlocking action. Furthermore, the input gear 410 rotates in the opposite direction. Understandably, this reverse rotation means that the direction of rotation of the input gear 410 is opposite to the direction of rotation of the input gear 410 when the external force acts on the actuating structure 40 to perform the unlocking action. Finally, the generator 41 converts the mechanical energy of the input gear 410 into electrical energy.

[0071] In this embodiment, the elastic element 403 is a tension spring. One end of the tension spring is connected to the slide plate 402, and the other end is connected to the lock housing 1. The lock housing 1 is provided with fastening screws or fastening pins, and the slide plate 402 is also provided with fastening screws or fastening pins. One end of the tension spring is fixed to the fastening screw or fastening pin on the lock housing 1, and the other end of the tension spring is fixed to the fastening screw or fastening pin on the slide plate 402.

[0072] It should be explained that in this embodiment, the elastic element 403 is preferably configured as a tension spring, but it is not limited to being configured as a tension spring. For example, it can also be configured as a spring, torsion spring, elastic band, etc., which will not be elaborated here. This embodiment will only be described in detail in the form of being configured as a tension spring.

[0073] Furthermore, two tension springs are symmetrically arranged on the slide plate 402. When the external force is applied to the actuation structure 40 to perform the unlocking action, the two tension springs undergo elastic deformation and accumulate elastic potential energy. After the external force is removed, the elastic potential energy of the two tension springs is converted into the kinetic energy of the input gear 410, and then converted into electrical energy through the generator 41.

[0074] In this embodiment, after the external force acting on the actuation structure 40 is removed, the elastic force of the elastic element 403 drives the slide plate 402 to slide in the opposite direction. The slide plate 402 drives the output gear 401 to rotate in the opposite direction through the rack 402A, which in turn drives the input gear 410 to rotate in the opposite direction. The generator 41 converts the mechanical energy of the input gear 410 into electrical energy. That is, whether it is during the process of driving the actuation structure 40 to unlock, or during the process of the external force being removed and the elastic element 403 driving the actuation structure 40 to reset, the input gear 410 will be driven to rotate, and the generator 41 will generate electricity, resulting in high electrical energy conversion efficiency.

[0075] Furthermore, two elastic elements 403 (i.e., tension springs) are symmetrically arranged on the sliding plate 402. When an external force is applied to the actuation structure 40 to unlock, the two tension springs undergo elastic deformation and accumulate elastic potential energy. After the external force is removed, the elastic potential energy accumulated by the two tension springs is converted into the kinetic energy of the input gear 410, and then converted into electrical energy through the generator 41. That is, during reset, the two tension springs overcome the load of the generator 41 to generate electricity, ensuring that the power generation module 4 in the lock has a high power conversion rate.

[0076] The tension spring is positioned at an angle to the sliding direction of the slide plate 402 (e.g., ...). Figure 5Angle A), which is between 10 and 30 degrees, is set between the sliding direction of the tension spring and the sliding plate 402. This angle fully utilizes the internal space of the lock housing 1, improves space utilization, and ensures a compact internal structure of the lock. Furthermore, during the unlocking process, as the sliding plate 402 slides and deforms the tension spring, this angle gradually decreases, ensuring a gradual change in the tension spring's shape and providing a good user experience.

[0077] In this embodiment, the actuation structure 40 further includes a handle 404. The lock housing 1 is provided with a handle chamber 10, and the handle 404 is rotatably mounted in the handle chamber 10. Specifically, a protruding post extends from the upper and lower sides of the handle 404, and a circular hole corresponding to the protruding post is provided on the handle chamber 10. The two protruding posts are respectively installed in the two circular holes, realizing the rotatable connection between the handle 404 and the handle chamber 10. When the lock is in the locked state, the handle 404 protrudes from the handle chamber 10, facilitating the user to perform the unlocking action; when the user squeezes the handle 404 to perform the unlocking action, the handle 404 can be accommodated in the handle chamber 10. It can be understood that in addition to setting the handle 404 to realize the input of the unlocking action, this embodiment can also realize it by pulling a handle or other means, which will not be described in detail here.

[0078] The handle 404 extends a lever arm 404A towards the slide plate 402. The lever arm 404A movably abuts against the slide plate 402. Specifically, the slide plate 402 has a through groove corresponding to the lever arm 404A, and the lever arm 404A movably passes through the through groove on the slide plate 402, movably abutting against the groove wall. When the handle 404 rotates, it abuts the slide plate 402 via the lever arm 404A, causing the slide plate 402 to slide. After the unlocking action is completed, when the tension spring pulls the slide plate 402 to reset, the slide plate 402 can also push against the lever arm 404A, causing the handle 404 to reset. That is, the tension spring not only resets the slide plate 402 but also resets the handle 404.

[0079] The sliding plate 402 has at least two guide grooves 402B along its sliding direction, and the locking housing 1 has guide protrusions (not shown in the figure) corresponding to the guide grooves 402B. The guide protrusions extend into the guide grooves 402B. The cooperation between the at least two guide grooves 402B and the at least two guide protrusions guides the sliding of the sliding plate 402, ensuring smooth movement and structural stability. It should be explained that to ensure the sliding plate 402 can slide, the length of the guide protrusions must be shorter than the length of the guide grooves 402B to avoid interfering with the movement of the sliding plate 402. By using the guide protrusions to abut against the two ends of the guide grooves 402B, the sliding stroke of the sliding plate 402 can be controlled, ensuring that the sliding plate 402 does not slide excessively, further ensuring structural stability.

[0080] The transmission method between the output gear 401 and the input gear 410 is described in detail below.

[0081] Optionally, in this embodiment, the input gear 410 and the output gear 401 can be directly meshed, and no other transmission components need to be provided between the input gear 410 and the output gear 401.

[0082] In another optional implementation, the transmission component between the input gear 410 and the output gear 401 is configured as a transmission gear set 42. A transmission gear set 42 is provided between the input gear 410 and the output gear 401. The transmission gear set 42 includes a first gear 421 and a second gear 422 arranged coaxially. The first gear 421 has fewer teeth than the second gear 422; that is, the first gear 421 is a pinion and the second gear 422 is a gear. The first gear 421 meshes with the output gear 401, and the second gear 422 meshes with the input gear 410. This configuration of the transmission gear set 42 increases the transmission ratio between the output gear 401 and the input gear 410. Compared to direct meshing, under the same conditions, the input gear 410 rotates more times, effectively improving the energy conversion efficiency of the generator 41.

[0083] In another optional implementation, the transmission component between the input gear 410 and the output gear 401 is configured as a transmission gear set 42. Two sets of transmission gear sets 42 are provided between the input gear 410 and the output gear 401. One set of transmission gear sets 42 includes a first gear 421 and a second gear 422 arranged coaxially, and the first gear 421 has fewer teeth than the second gear 422, i.e., the first gear 421 is a pinion and the second gear 422 is a gear. The other set of transmission gear sets 42 includes a third gear 423 and a fourth gear 424 arranged coaxially, and the third gear 423 has fewer teeth than the fourth gear 424, i.e., the third gear 423 is a pinion and the fourth gear 424 is a gear. The output gear 401 meshes with the first gear 421, the second gear 422 meshes with the third gear 423, and the fourth gear 424 meshes with the input gear 410. Similarly, the arrangement of two sets of transmission gears 42 can increase the transmission ratio between the output gear 401 and the input gear 410. Compared with the direct meshing method, under the same conditions, the input gear 410 rotates more times, which can effectively improve the power conversion rate of the generator 41.

[0084] In another optional implementation, the transmission component between the input gear 410 and the output gear 401 is configured as a transmission gear set 42. At least three sets of the transmission gear sets 42 are provided between the input gear 410 and the output gear 401. The structure is similar to that of setting two sets of transmission gear sets 42, and will not be described in detail here.

[0085] Understandably, for example, if the transmission ratio between the output gear 401 and the input gear 410 is set to 28, then when the output gear 401 rotates a quarter turn, the input gear 410 will rotate 7 turns, ensuring that the kinetic energy input by the input gear 410 to the generator 41 is sufficient, thereby ensuring the power generation of the generator 41 and the power generation rate of the power generation module 4.

[0086] In this embodiment, by selectively setting one, two, or at least three transmission gear sets 42 between the input gear 410 and the output gear 401, the transmission ratio between the output gear 401 and the input gear 410 can be effectively increased. During the unlocking or resetting process, the small-range rotation of the output gear 401 (less than one rotation) can make the input gear 410 rotate multiple times, thereby effectively ensuring the power generation efficiency. That is, the setting of the transmission gear set 42 can effectively improve the power generation efficiency of the power generation module 4 in the lock.

[0087] To facilitate installation and disassembly, in this embodiment, a mounting bracket (not shown in the figure) is provided in the lock housing 1. The mounting bracket is fixedly connected to the lock housing 1. The transmission gear set 42 and the generator 41 are both mounted on the mounting bracket, and the output gear 401 is also rotatably mounted on the mounting bracket. Mounting the components of the generator module 4 on the mounting bracket facilitates modularity and convenient assembly and disassembly.

[0088] In this embodiment, the self-generating lock also includes an IC card antenna plate 6, which is disposed in the lock housing 1 and electrically connected to the control circuit. That is, the lock in this embodiment requires IC card identification when unlocking. The lock housing 1 has a card slot (not shown in the figure) for inserting an IC card, with an upward-facing opening to prevent the IC card from falling out after insertion. Furthermore, the IC card antenna plate 6 is disposed inside the card slot to ensure sensitive IC card recognition. When unlocking, the IC card needs to be inserted into the card slot for identification, ensuring the lock's security performance.

[0089] The circuit board 3 is equipped with a capacitor 30, and the electrical energy converted by the generator 41 can be stored in the capacitor 30. The electrical energy generated by the power generation module 4 can supply power to other electrical components in the lock, making it convenient to use and eliminating the need for batteries.

[0090] As an optional implementation, the locking member 2 in this embodiment is a latch, which is telescopically mounted on the lock housing 1 for unlocking and locking. The latch can also be unlocked and locked by rotation, which can be achieved by setting a push block 21 on the latch to move against it, and setting a spring 22 between the push block 21 and the lock housing 1. The push block 21 and the latch are rotatably connected. This is prior art and will not be described in detail here.

[0091] The clutch 5 includes a motor 50 and a gearbox 51. Specifically, in this embodiment, the gearbox 51 can be configured as a reduction gearbox. The motor 50 is electrically connected to the control circuit and to the gearbox 51 to drive the gearbox 51. The gearbox 51 has an output arm 510, and a locking block 52 is provided on the output arm 510. The motor 50 can drive the output arm 510 to extend and retract, so that the locking block 52 locks onto or unlocks from the latch. When the latch is in the locked position, the motor 50 in the clutch 5 can drive the locking block 52 to lock onto the latch, which can ensure the locking reliability of the latch when locked. Specifically, the locking block 52 has an inclined surface, and the latch also has an inclined surface corresponding to the inclined surface. When the locking block 52 locks the latch in the locked position, the inclined surface on the locking block 52 abuts and adheres to the inclined surface on the latch, and the latch cannot retract.

[0092] like Figures 1-3 as well as Figure 5 As shown, and with the directions of these figures as a reference, the working principle of the self-generating lock in this embodiment is as follows:

[0093] When the lock is in the locked state, the locking member 2 is in the locked position and extends out of the lock housing 1. At this time, the locking block 52 is driven by the clutch 5 to the extended position. The locking block 52 presses against the locking member 2, and the locking member 2 cannot retract to switch to the unlocked position. The handle 404 is also in the extended position at the handle chamber 10.

[0094] When a user needs to unlock the lock, they insert the IC card corresponding to the lock into the corresponding IC card slot on the lock housing 1; squeeze the handle 404, causing it to rotate relative to the handle chamber 10, thus moving the handle 404 into the handle chamber 10; the actuating arm 404A on the handle 404 pushes against the slide plate 402, causing the slide plate 402 to slide from left to right. At this time, the guide groove 402B on the slide plate 402 engages with the guide protrusion on the lock housing 1 to ensure reliable sliding of the slide plate 402; the slide plate 402 pulls two tension springs, causing them to stretch and undergo elastic deformation, accumulating elastic potential energy; in addition, when the slide plate 402 slides, it meshes with the drive wheel 401A on the output gear 401 through the rack 402A on it, causing the drive wheel 401A of the output gear 401 to rotate, driving the driven wheel 401B to rotate. The driven wheel 401B drives the transmission gear set 42 to rotate; the transmission gear set 42 drives the input gear 410 to rotate, that is, the input gear 410 inputs kinetic energy to the generator 41 at this time, the generator 41 converts the kinetic energy input by the input gear 410 into electrical energy to generate electricity; the electrical energy generated by the generator 41 is transmitted to the circuit board 3 through the control circuit, and the circuit board 3 supplies power to each electrical component in the lock; since the lock is now powered on, the IC card antenna board 6 will identify the IC card. After the identification is successful, the clutch 5 is powered on and the control circuit controls its motor 50 to rotate, which drives the output arm 510 at the output end of the gearbox 51 to move away from the locking member 2, so that the lock block 52 is disengaged from the locking member 2 and no longer locks the locking member 2 in the locked position. The locking member 2 retracts and switches to the unlocked position, completing the unlocking.

[0095] When the user releases the handle 404, the elastic potential energy of the two tension springs acts on the slide plate 402, causing the slide plate 402 to slide from right to left and reset, reserving travel for the next power generation. During the reset process of the slide plate 402, the pull arm 404A is pulled to reset the handle 404, which then extends from the handle compartment 10 for easy operation by the user next time. In addition, when the slide plate 402 slides from right to left, the rack 402A on it meshes with the drive wheel 401A on the output gear 401, causing the drive wheel 401A to rotate in the opposite direction, which in turn drives the driven wheel 401B to rotate in the opposite direction. The driven wheel 401B drives the transmission gear set 42 to rotate. The transmission gear set 42 drives the input gear 410 to rotate in the opposite direction, and the generator 41 converts the kinetic energy input by the input gear 410 into electrical energy to generate electricity.

[0096] In this solution, the self-generating lock includes: a lock housing 1; a locking member 2, movably disposed in the lock housing 1 and configured to move between a locked position and an unlocked position to achieve locking and unlocking of the lock; a circuit board 3, disposed in the lock housing 1, and equipped with a control circuit; a power generation module 4, disposed in the lock housing 1, including an actuation structure 40 and a generator 41, the generator 41 being electrically connected to the control circuit, and an input gear 410 being disposed on the shaft of the generator 41; the actuation structure 40 including an output gear 401, the output gear 401 directly meshing with the input gear 410 for transmission or indirectly meshing with it through at least one transmission component; and a clutch 5, disposed in the lock housing 1 and electrically connected to the control circuit; when the actuation structure 40 is driven to unlock, the output gear 401 rotates, driving the input gear 410 to rotate, and the generator 41 converts the mechanical energy input by the input gear 410 into electrical energy. Its advantages are that the self-generating lock has a simple and compact structure and high electrical energy conversion efficiency.
