Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door locks, in particular to an encrypted power-loss prevention door lock. Background Art
[0002] Encrypted power-loss lock technology is a significant innovation in modern security. It combines encryption and power management technologies to enhance door lock security and reliability. While maintaining the basic functionality of a traditional door lock, it also uses encryption to protect user identity and unlocking records. Furthermore, a power-loss-proof design ensures normal operation or provides a warning in the event of a power outage.
[0003] Existing encrypted, power-deficit-proof door locks are equipped with an internal power monitoring system that monitors the charge level of the main battery (typically a lithium battery) in real time. This system accurately assesses the remaining battery charge and issues a warning signal when the battery is nearing depletion. The lock also incorporates intelligent power switching logic, which uses this power monitoring system data to determine whether to switch to the backup battery. Once the main battery charge falls below a preset threshold, the power switching logic automatically activates, preparing to switch the lock's power supply to the backup battery. Consequently, the built-in backup lithium battery and automatic switching system lead to relatively high manufacturing costs for the lock. The automatic replacement of the lithium battery upon reaching the threshold prevents the battery from being fully depleted, reducing the lock's battery life. If the threshold is too low, insufficient power is available to maintain the automatic switching system, or if a system failure prevents the switchover, the backup battery becomes ineffective. Furthermore, automatic switching can drain the backup battery during extended periods of absence. Utility Model Content
[0004] (1) Technical problems solved: In response to the shortcomings of the existing technology, the present invention provides an encrypted anti-power-deficit door lock, which utilizes the external structure of the door lock to achieve convenient manual switching of the power supply, avoiding power-off failures caused by system failures or insufficient battery power, and reducing the manufacturing cost and selling price of the encrypted anti-power-deficit door lock.
[0005] (2) Technical solution: In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: an encrypted anti-power shortage door lock, comprising a lock body, a battery compartment installed inside the lock body, the battery compartment being used to place lithium batteries and spare batteries, the upper inner surface of the battery compartment being designed with wiring terminals and spare wiring terminals, the battery compartment being composed of a limit baffle and a slide plate, there being two limit baffles, which are respectively located on both sides of the battery compartment and fixedly connected to the inner surface of the battery compartment, the lower surface of the limit baffle and the lower surface of the battery compartment being located in the same horizontal plane; the slide plate being composed of a slider and a push plate, a lithium battery being placed on the upper surface of the push plate, the lower surface of the push plate coincides with the upper surface of the limit baffle, a slider being fixedly connected below the push plate, and the slider having the freedom to slide along the direction of the limit baffle.
[0006] Preferably, a password button and a handle are designed on the upper surface of the lock body, and the lithium battery and the backup battery supply power to the structure above the lock body through the wiring terminals and the backup wiring terminals. A slide groove is designed on the lower surface of the lock body, and the slider passes through the slide groove to reach the outside of the lock body. The slider can move horizontally along the direction of the slide groove together with the push plate through the movement of the outer part of the lock body.
[0007] Preferably, the push plate is designed with a slope near one end of the spare battery, the length of the push plate is the same as that of the lithium battery, the direction in which the slide groove is opened is along the front of the battery compartment facing the rear surface of the battery compartment, and there is a gap between the slide groove and the rear surface of the battery compartment.
[0008] Preferably, the width of the battery compartment is the same as that of the lithium battery, the height is the same as the sum of the heights of the lithium battery and the push plate below, and the length is the length of the lithium battery plus the length of the spare battery. A cover plate is installed on the outside of the battery compartment, the width of the cover plate is the same as that of the lock body, and the cover plate and the lock body are detachably connected.
[0009] Preferably, the upper surfaces of the lithium battery and the backup battery are respectively designed with a battery interface and a backup battery interface, the lithium battery and the backup battery are of the same model and size, and the battery interface and the backup battery interface are circuit-connected through the wiring terminals and the backup wiring terminals on the upper surface of the battery compartment. Beneficial effects
[0010] At the same time, due to the movement of the lower push plate, the lithium battery falls to the upper surface of the lower limit baffle, which is one push plate height away from the upper terminal, thereby disconnecting the lithium battery from the terminal. This design allows users to manually select and replace the power supply battery according to the required time, preventing the relatively high manufacturing cost of the door lock due to the built-in backup lithium battery and automatic switching system; the automatic replacement door lock automatically replaces the lithium battery after reaching the threshold, so that the power inside the lithium battery cannot be fully used up, reducing the battery life of the door lock; if the threshold of the automatic replacement system is too low, the power is insufficient to maintain the automatic switching system, or the system fails and cannot switch, the backup battery will not be effective; and when the user is away from home for a long time, the automatic switching may cause the backup battery to run out of power, etc.
[0011] 2. This encrypted power-loss prevention door lock has a push plate that is the same length as the lithium battery. The push plate has a sloped design near the backup battery end, and the slide runs along the front of the battery compartment toward the rear surface of the battery compartment, with a gap between the slide and the rear surface. This design ensures that in the initial state of the push plate, because the slide has not yet reached the rear surface of the battery compartment, a small portion of the push plate is below the backup battery. The sloped push plate facing the backup battery prevents the push plate from being completely lifted up and hitting the backup terminal, preventing power from being supplied. When switching batteries, the push plate, already with a sloped portion below the backup battery, allows the user to easily push the slider toward the backup battery, lifting the backup battery along the push plate. Since the push plate is the same length as the backup battery, when the push plate is completely below the backup battery, there is no obstruction below the corresponding position of the lithium battery, allowing the lithium battery to fall onto the upper surface of the lower limit plate. This design makes battery switching easier and prevents the inactive battery connector from contacting the terminal, preventing short circuits caused by poor contact and reducing safety hazards.

[0021] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.
[0023] See also Figure 1-7, an encrypted anti-power shortage door lock includes a lock body 1, a battery compartment 3 is installed inside the lock body 1, the battery compartment 3 is used to place a lithium battery 4 and a spare battery 510, the upper inner surface of the battery compartment 3 is designed with a wiring terminal 311 and a spare wiring terminal 312, the battery compartment 3 is composed of a limit baffle 310 and a slide plate 320, there are two limit baffles 310, which are respectively located on both sides of the battery compartment 3 and fixedly connected to the inner surface of the battery compartment 3, and the lower surface of the limit baffle 310 is in the same horizontal plane as the lower surface of the battery compartment 3; the slide plate 320 is composed of a slider 322 and a push plate 321, a lithium battery 4 is placed on the upper surface of the push plate 321, the lower surface of the push plate 321 coincides with the upper surface of the limit baffle 310, and a slider 322 is fixedly connected below the push plate 321, and the slider 322 has the freedom to slide along the direction of the limit baffle 310.
[0024] like Figure 1 and Figure 3 As shown, the upper surface of the lock body 1 is designed with a password button 110 and a handle 120 for realizing the basic functions of the electronic door lock. The lithium battery 4 and the backup battery 5 supply power to the upper structure of the lock body 1 through the wiring terminal 311 and the backup wiring terminal 312. This structure is conventional and will not be described in detail here. The lower surface of the lock body 1 is designed with a slide groove 130. The slider 322 passes through the slide groove 130 to reach the outside of the lock body 1. The slider 322 can move horizontally along the slide groove 130 together with the push plate 321 by moving the outer part of the lock body 1. When the door lock is closed, the user can use the slider 322 protruding from the lower surface of the lock body 1 to move the push plate 321 inside the battery compartment 3.
[0025] like Figure 3 and Figure 7 As shown, the push plate 321 is designed with a slope at one end close to the spare battery 510. The length of the push plate 321 is the same as that of the lithium battery 4. The direction in which the chute 130 is opened is along the front of the battery compartment 3 toward the rear surface of the battery compartment 3. There is a gap between the chute 130 and the rear surface of the battery compartment 3, so that when the push plate 321 is in the initial state, since the chute 130 has not reached the rear surface of the battery compartment 3, a small part of the push plate 321 is below the spare battery 510. The push plate 321 facing the spare battery 510 is designed with a slope. Even if there is a small part of the push plate 321 below the spare battery 510 , and it will not be lifted up completely and hit the spare terminal 312, making it impossible to power on; when it is necessary to switch batteries, since there is a sloped push plate 321 under the spare battery 510, the user can easily push the slider 322 toward the spare battery 510, and the spare battery 510 below is lifted along the push plate 321. The length of the push plate 321 is the same as that of the spare battery 510, so when the push plate 321 is completely located at the bottom of the spare battery 510, there is no obstacle at the corresponding position below the lithium battery 4, and the lithium battery 4 falls into the upper surface of the lower limit baffle 310.
[0026] like Figure 1-2 As shown, the width of the battery compartment 3 is the same as that of the lithium battery 4, the height is the same as the sum of the heights of the lithium battery 4 and the push plate 321 below, and the length is the length of the lithium battery 4 plus the length of the spare battery 510. In this way, when the lithium battery 4 and the spare battery 510 are placed in the battery compartment 3 at the same time, the batteries have no freedom of movement except in the vertical direction. A cover plate 2 is installed on the outside of the battery compartment 3. The width of the cover plate 2 is the same as that of the lock body 1. The cover plate 2 is detachably connected to the lock body 1. The user can remove the cover plate 2 to replace the battery after the lithium battery 4 and the spare battery 510 are exhausted.
[0027] like Figure 4-5 As shown, the upper surfaces of the battery and the backup battery 510 are respectively designed with a battery interface 410 and a backup battery interface 510. The lithium battery 4 and the backup battery 510 are of the same model and size. The battery interface 410 and the backup battery interface 510 are connected in circuit through the wiring terminal 311 and the backup wiring terminal 312 on the upper surface of the battery compartment 3. In the initial state, the lithium battery 4 is placed on the upper surface of the lower push plate 321, and the battery interface 410 on the lithium battery 4 is just aligned with the wiring terminal 311 on the upper surface of the battery compartment 3. At this time, the lithium battery 4 supplies power to the door lock; when the lithium battery 4 is exhausted, the user can push the slider 322 along the slide groove 130 from the outside, The slider 322 moves with the upper push plate 321 toward the direction of the backup battery 510. The backup battery interface 510 above the backup battery 510 is originally one push plate 321 height away from the backup terminal 312 above the battery compartment 3. After the push plate 321 is pushed under the backup battery 510, the backup terminal 312 is connected to the backup battery interface 510, and the backup battery 510 is converted to power the door lock. At the same time, due to the movement of the lower push plate 321, the lithium battery 4 falls to the upper surface of the lower limit baffle 310, and is one push plate 321 height away from the upper terminal 311, thereby disconnecting from the terminal 311.
