[0001] This utility model relates to the field of door locks, specifically to a self-powered smart door lock. Background Technology

[0002] In the field of door lock technology, traditional mechanical locks have long dominated, requiring users to carry mechanical keys to unlock them. However, with technological advancements and increasing demands for convenient living, smart locks have emerged and are gradually gaining popularity. Smart locks, with their diverse unlocking methods (such as fingerprint recognition, password unlocking, and remote unlocking via mobile app), effectively eliminate the inconvenience of carrying mechanical keys, greatly improving the convenience of daily entry and exit. Therefore, more and more people are choosing smart locks to replace traditional mechanical locks.

[0003] However, existing smart locks have significant technical flaws, as their normal operation is highly dependent on the power carried by the battery pack. Once the battery pack is depleted, the smart lock will lose power and be unable to perform normal unlocking operations. At this time, users will find it difficult to open the lock from the outside when they return home, and will have to seek help from professional locksmiths or use other complex and time-consuming emergency unlocking methods. This undoubtedly causes great inconvenience to people's normal entry and exit, reduces the user experience of smart locks, and also limits the further promotion and application of smart locks.

[0081] The self-powered smart door lock of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0082] Reference Figures 1 to 6 As shown, the self-powered smart door lock provided according to an embodiment of this utility model includes an inner door lock installed on the inside of the door panel, a lock cylinder suitable for installation inside the door panel, and an outer door lock suitable for installation on the outside of the door. The inner door lock is equipped with a rechargeable battery assembly, and the outer door lock includes a lock body 10, a handle 12, a first power generation component 20, a second power generation component 30, and a perovskite photovoltaic energy storage panel 40. The inner door lock and the lock cylinder are existing technologies and will not be described further here.

[0083] The lock body 10 is installed on the outer side of the door panel, and the outer surface of the lock body 10 is provided with a rotating component 11 that can rotate along its own axis.

[0084] The handle 12 is rotatably disposed on the surface of the lock body 10, and one end passes through the lock body 10 via a pivot 121 and is connected to the lock cylinder, so as to drive the lock cylinder to unlock by rotating the handle 12.

[0085] The first power generation component 20 is disposed inside the lock body 10, and one end is connected to the rotating shaft 121 so as to drive the first power generation component 20 to generate electrical energy by the kinetic energy of the rotation of the rotating shaft 121 when the door is opened, and store the generated electrical energy in the rechargeable battery assembly.

[0086] The second power generation component 30 is disposed inside the lock body 10. One end of the rotating member 11 is connected to the second power generation component 30 so that the second power generation component 30 can be driven to generate electricity by rotating the rotating member 11, and the generated electrical energy is stored in the rechargeable battery assembly.

[0087] The 40 perovskite photovoltaic energy storage panels are disposed on the surface of the lock body 10 to convert light energy into electrical energy and store it in the rechargeable battery component.

[0088] Based on the above, the first power generation component 20 generates electricity using the kinetic energy of the rotating shaft 121 when the door is opened, which can charge the rechargeable battery component to extend the battery's range and reduce the occurrence of running out of power. At the same time, the second power generation component 30 generates electricity by rotating the rotating part 11 and stores the electrical energy in the rechargeable battery component, effectively solving the problem of the smart door lock's excessive dependence on battery power. When the rechargeable battery component is depleted, it can be manually powered to avoid the problem of being unable to open the door due to power depletion.

[0089] It is understandable that the perovskite photovoltaic energy storage panel 40 has the advantage of generating electricity in low light conditions. It can convert weak light into electrical energy. Door locks are generally located in corridors, where the light they receive is not strong. The perovskite photovoltaic energy storage panel 40 can convert weak light in the corridor to generate electrical energy, thereby improving the battery life of the smart door lock. Moreover, its manufacturing cost is lower than that of other materials, which is conducive to cost control.

[0090] Preferably, in one embodiment of the present invention, the first power generation component 20 includes a transmission component 21 and a first generator 22.

[0091] The transmission component is located inside the lock body 10, and one end of the transmission component is connected to the rotating shaft 121.

[0092] The first generator 22 is located inside the lock body 10 and connected to the other end of the transmission assembly, so that the kinetic energy on the rotating shaft 121 is transmitted to the first generator 22 through the transmission assembly, so that the first generator 22 generates electricity.

[0093] The first generator 22 is connected to the rechargeable battery assembly to deliver the generated electrical energy to the rechargeable battery assembly.

[0094] In this way, by connecting the rotating shaft 121 and the first generator 22 through the transmission component 21, the kinetic energy of the rotating shaft 121 when the door is opened can be stably and efficiently transmitted to the first generator 22, ensuring that the first generator 22 can effectively use the kinetic energy of the rotating shaft 121 to generate electricity, thereby improving the efficiency of converting kinetic energy into electrical energy.

[0095] Preferably, in one embodiment of the present invention, the transmission assembly includes a gear ring 211, a first gear 212, a second gear 213, a first transmission belt 214, and a second transmission belt 215.

[0096] The gear ring 211 is fitted onto the rotating shaft 121.

[0097] The first gear 212 is located on one side of the gear ring 211 and meshes with the gear ring 211.

[0098] The second gear 213 is located below the first gear 212.

[0099] One end of the first transmission belt 214 is fitted onto the first gear 212, and the other end is fitted onto the second gear 213.

[0100] One end of the second transmission belt is fitted onto the second gear 213, and the other end is fitted onto the input shaft of the first generator 22.

[0101] Thus, the gear ring 211 is fitted onto the rotating shaft 121, and the first gear 212 meshes with the gear ring 211. The power of the first gear 212 is transmitted to the second gear 213 via the first transmission belt 214, and then to the input shaft of the first generator 22 via the second transmission belt 215. This multi-stage transmission method allows for flexible adjustment of the transmission ratio, ensuring that the kinetic energy of the rotating shaft 121 at different speeds is efficiently and stably transmitted to the first generator 22, enabling the first generator 22 to generate electricity effectively at different door opening speeds. The compact layout of each transmission component, with the gear ring 211, gears, and transmission belts working together, achieves effective power transmission within a limited space without increasing the overall size of the smart lock. This facilitates the installation and layout of the smart lock within the door panel and promotes the miniaturization and lightweight design of the smart lock.

[0102] Preferably, in one embodiment of the present invention, the outer surface of the toothed ring 211 is provided with a plurality of first teeth 2111 along its circumference, and the plurality of first teeth 2111 are inclined in a clockwise direction.

[0103] The outer surface of the first gear 212 is provided with a plurality of second teeth 2121 along its circumference. The plurality of second teeth 2121 are inclined in a counterclockwise direction, and the first teeth 2111 and the second teeth 2121 mesh with each other.

[0104] Thus, the first tooth 2111 on the outer surface of the gear ring 211 is inclined counterclockwise, and the second tooth 2121 on the outer surface of the first gear 212 is inclined clockwise, and the two mesh with each other. This special tooth inclination design allows the first tooth 2111 and the second tooth 2121 to mesh more tightly and smoothly when the shaft 121 drives the gear ring 211 to rotate when the door is opened, avoiding slippage. This efficiently transmits the power of the gear ring 211 to the first gear 212, improving the efficiency of power transmission and ensuring that the first generator 22 can obtain sufficient kinetic energy to generate electricity.

[0105] Preferably, in one embodiment of the present invention, the first tooth 2111 is pivotally connected to the tooth ring 211 on the side of the inclined direction, and the first tooth 2111 is connected to the tooth ring 211 on the side opposite to the inclined direction through a spring piece 2112.

[0106] Thus, in one embodiment of this utility model, the first tooth 2111 is pivotally connected to the gear ring 211 on the side of the inclined direction, while the first tooth 2111 on the side away from the inclined direction is connected to the gear ring 211 via a spring piece 2112. Therefore, when the handle 12 is rotated, the gear ring 211 can be driven to rotate clockwise, thereby driving the first gear 212 to rotate, so as to drive the first generator 22 to generate electricity. When the door opening action is completed, the handle 12 rotates back. At this time, the first tooth 2111 and the second tooth 2121 abut against each other, causing the first tooth 2111 to pivot due to pressure, so as to shorten the extension distance, thereby realizing the rotation with the rotating shaft 121 without driving the first gear 212 to rotate, so as to ensure the normal rotation of the handle 12.

[0107] Preferably, in one embodiment of the present invention, the rotating component 11 includes a rotating column 111, a connecting shaft 112, and a driving platform 113.

[0108] The lock body 10 has mounting holes on its surface, and one end of the rotating column 111 is located in the mounting holes and can rotate along its own axis.

[0109] The connecting shaft 112 is connected to one end of the rotating column 111 and is coaxially arranged with the rotating column 111. The other end of the rotating column 111 is connected to the input shaft of the second power generation component 30.

[0110] The drive platform 113 is connected to the other end of the rotating column 111 to drive the rotating column 111 to rotate.

[0111] Thus, one end of the rotating column 111 is located in the mounting hole on the surface of the lock body 10 and can rotate along its own axis. This mounting method ensures the smooth rotation of the rotating column 111 and reduces frictional resistance during rotation. The connecting shaft 112 is coaxially arranged with the rotating column 111, which further enhances the stability of the rotation of the rotating column 111, allowing the drive platform 113 to drive the rotating column 111 to rotate more easily, providing a foundation for the stable power generation of the second power generation component 30.

[0112] The other end of the rotating column 111 is connected to the input shaft of the second power generation component 30, which can directly and efficiently transmit the power applied to the rotating column 111 by the drive platform 113 to the second power generation component 30, ensuring that the second power generation component 30 can respond to the rotation of the rotating column 111 in a timely manner and generate electricity, thereby improving the efficiency of energy conversion.

[0113] Preferably, in one embodiment of the present invention, a drive arm 114 is further included. The surface of the drive platform 113 is provided with a storage groove 115. The drive arm 114 is rotatably connected in the storage groove 115 and can switch between a first state and a second state.

[0114] When the drive arm 114 is in the first state, the drive arm 114 is stored in the storage slot 115. When the drive arm 114 is in the second state, the drive arm 114 extends toward the drive platform 113.

[0115] Thus, when the drive arm 114 is in the first state, it is retracted into the storage slot 115. This design effectively saves space when the drive arm 114 is not in use, preventing it from protruding and occupying extra space. This makes the overall appearance of the smart lock more concise and compact, which is beneficial for the installation and layout of the smart lock on the door panel. It also reduces the risk of collisions and scratches that may occur due to the exposed drive arm 114. The drive arm 114 can switch between the first and second states. When the drive arm 114 is needed to drive the rotating part 11, it is switched to the second state and extends towards the drive platform 113, making it convenient for users to operate and making rotation less strenuous. After use, it can be retracted into the storage slot 115. The operation is simple and flexible, improving the user experience and meeting the needs of different usage scenarios.

[0116] Preferably, in one embodiment of the present invention, the other end of the drive arm 114 is provided with a gripping part 116, and one end of the storage groove 115 is provided with a recessed part 1151.

[0117] When the drive arm 114 is in the first state, the gripping part 116 is inserted into the groove part 1151.

[0118] Thus, when the drive arm 114 is in the first state, the grip portion 116 is inserted into the groove portion 1151. This design makes the drive arm 114 more stable when stored, and it is not easy for it to easily pop out of the storage slot 115 due to accidental touch or vibration, ensuring the stability of the drive arm 114 in the stored state and further improving the compactness and reliability of the overall structure of the smart door lock. The grip portion 116 makes it easy for the operator to hold and rotate the drive arm 114, making rotation more effortless. Advantageously, a magnetic piece can also be provided in the groove portion 1151, and a metal piece can be provided on the grip portion 116 to form a magnetic fixation.

[0119] Preferably, in one embodiment of the present invention, the drive arm 114 includes a fixed arm 1141 and a telescopic arm 1142.

[0120] One end of the fixed arm 1141 is pivotally connected to the storage slot 115.

[0121] The telescopic arm 1142 is telescopically inserted into the other end of the fixed arm 1141, and the gripping part 116 is provided at the other end of the telescopic arm 1142.

[0122] Thus, the telescopic arm 1142 is telescopically inserted into the other end of the fixed arm 1141. The user can adjust the extension length of the telescopic arm 1142 according to actual needs, thereby changing the overall length of the drive arm 114, further reducing the force required for drive, and making rotation easier and less strenuous.

[0123] Preferably, in one embodiment of the present invention, the surface of the lock body 10 is provided with a fingerprint unlocking component 13 and a password unlocking component 14, so as to control the unlocking of the lock cylinder by fingerprint and password.

[0124] In this way, users can choose to unlock the smart door lock by fingerprint or password according to their own needs and habits, without having to carry traditional keys, avoiding the inconvenience caused by lost or forgotten keys, and greatly improving the convenience of opening the door.
