Description

Technical Field

[0001] The present application relates to the technical field of smart door locks, and in particular to a smart lock with a hidden mechanical keyhole. Background Art

[0002] Smart door locks have emerged with the development of smart technology. Compared with mechanical locks, they are more convenient and safer. However, they also have some defects. For example, if the battery of the smart door lock runs out or the line fails, the user will not be able to open the door by entering a password, fingerprint unlocking or facial unlocking. Therefore, the traditional mechanical keyhole is usually retained on the smart door lock, which mainly serves the purpose of emergency unlocking.

[0003] In the related art, in order to ensure safety and aesthetics, the mechanical keyhole of the smart door lock is generally hidden inside the door lock. When emergency unlocking is required, a press-and-pop method is usually used to open the cover covering the mechanical keyhole to expose the internal mechanical keyhole. In addition, the related art also uses a sliding cover structure, which can cover the mechanical keyhole. When emergency unlocking is required, the mechanical keyhole can be exposed by sliding the sliding cover up and down.

[0004] The problem with the related technology is that the structure that makes the cover plate press and pop up mainly relies on a spring. When the door lock is used for a long time, the spring is likely to relax and the cover plate cannot cover the keyhole, leaving the keyhole exposed. The problem with the sliding cover structure is that after long-term use, the fitting gap between the sliding cover and the door lock will continue to increase, which may easily cause the sliding cover to loosen and fail to effectively cover the keyhole, thereby affecting the overall safety and aesthetics of the door lock.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a smart lock with a hidden mechanical keyhole. Figure 1 A smart lock with a hidden mechanical keyhole includes a front panel assembly 1 and a rear panel assembly 5 arranged on the outer and inner sides of the door body, wherein the inner side of the door body refers to the side of the door body facing the room, and the outer side refers to the side facing the outside of the room. It can be understood by those skilled in the art that it should also include components such as a lock body and a lock core. This part of the content belongs to the prior art and is not limited here.

[0036] Reference Figure 1 The front panel assembly 1 includes a front panel body 11. The front panel body 11 is a rectangular shell-like structure with a chamber formed therein. A sensing module 16 and a main control module 17 are installed in the chamber. The sensing module 16 is electrically connected to the main control module 17. A sealing plate 3 is installed on the side of the front panel body 11 facing the door body. The sealing plate 3 is used to provide protection for the various components in the chamber, reduce dust and impurities entering the chamber, and ensure the normal operation of the smart door lock. A fixing plate 4 is further installed on the side of the sealing plate 3 facing the door body. The fixing plate 4 is used to connect the front panel body 11 to the door body.

[0037] A rectangular groove is formed on one side of the front panel body 11 away from the door body, which is recessed along its width direction. A touch screen group 18 is arranged in the rectangular groove. The touch screen group 18 is electrically connected to the sensing module 16 and the main control module 17. The touch screen group 18 is used to input unlocking passwords, record fingerprints and other information. By scanning the user's fingerprint information, it is compared with the fingerprint data stored in the main control module 17 to confirm the user's identity and open the door lock. It is understandable that in order to realize the fingerprint recognition function, a fingerprint recognition sensor should be installed in the chamber, which can capture the displacement characteristics of the user's fingerprint. When the user places his finger on the fingerprint recognition sensor, the main control module 17 will compare its fingerprint image with the recorded fingerprint information. If the comparison passes, the door lock is unlocked.

[0038] The principle of unlocking the door lock by entering the unlocking password is roughly as follows: a password input interface is provided in the chamber, and the user only needs to enter the correct password in the interface to unlock the door lock. This part of the content belongs to the conventional technology in this field and will not be described here. In actual application, fingerprint recognition or password input can be used alone to unlock the door, or fingerprint recognition and password input can be combined to unlock the door.

[0039] Reference Figure 2 The rear panel assembly 5 includes a rear panel body 51. A battery slot is formed on one side of the rear panel body 51 away from the door body. A power supply 52 is installed in the battery slot. The power supply 52 is electrically connected to each electrical component of the front panel assembly 1 through a cable to supply power to each electrical component. A cover plate is detachably installed at the notch of the battery slot to provide protection for the power supply 52. ​​The power supply 52 preferably uses lithium batteries, and the number of lithium batteries is eight, of which four are main power supply batteries and the other four are backup power supply batteries.

[0040] Reference Figure 3 A fixing block 19 is provided on a side of the front panel body 11 away from the door body, and the fixing block 19 is provided below the touch screen group 18. A handle 12 is installed on a side of the fixing block 19 away from the front panel body 11. The handle 12 is preferably a rectangular plate structure, the length of which is not greater than the length of the front panel body 11, and the height is less than the difference between the heights of the front panel body 11 and the touch screen group 18 (that is, the orthographic projection of the handle 12 on the front panel body 11 does not intersect with the touch screen group 18), so as to avoid interference when the user inputs information through the touch screen group 18.

[0041] Furthermore, a mechanical lock hole 13 is opened on the handle 12, and the mechanical lock hole 13 passes through the front panel body 11, the sealing plate 3 and the fixing plate 4. A receiving groove 14 is opened on the side of the handle 12 away from the front panel body 11, and one end of the mechanical lock hole 13 is located in the receiving groove 14.

[0042] A sliding cover 15 is slidably installed in the accommodating groove 14. The specific installation method can be that limiting sliding grooves are further opened on both sides of the accommodating groove 14, and limiting sliding rails are correspondingly formed on both sides of the sliding cover 15. The limiting sliding rails and the limiting sliding grooves cooperate with each other, and the extension directions of the two are parallel to the height direction of the handle 12, so that the sliding cover 15 can slide up and down relative to the handle 12 to expose or hide the mechanical lock hole 13 in the accommodating groove 14.

[0043] Reference Figure 3 and Figure 4 A limiting mechanism 2 is provided on the handle 12, and the limiting mechanism 2 includes a first limiting component 21 and a second limiting component 22. A horizontally extending cross slide is provided inside the fixed block 19, and the cross slide extends in a direction close to the handle 12 and passes through a surface of the fixed block 19 facing the handle 12. The first limiting component 21 includes a cross connecting rod 212 slidably installed in the cross slide, and a locking piece 213 is provided at one end of the cross connecting rod 212 close to the handle 12. A pushing groove is provided on the lower surface of the fixed block 19, and the first limiting component 21 also includes a hidden push plate 211 slidably arranged in the pushing groove, and the hidden push plate 211 is connected to the cross connecting rod 212. The user applies a pushing force to the hidden push plate 211 to make the hidden push plate 211 slide in the pushing groove, thereby driving the cross connecting rod 212 to slide in the cross slide.

[0044] Furthermore, a locking groove that matches the locking member 213 is provided on the side of the slide cover 15 facing the mechanical lock hole 13. When the first limit assembly 21 limits the position of the slide cover 15, the locking member 213 is locked in the locking groove, and the hidden push plate 211 is not subjected to external force. When the user pushes the hidden push plate 211 away from the handle 12, the locking member 213 is disengaged from the locking groove, and the slide cover 15 can slide up and down. It should be noted that a space for the cross link 212 to slide and for accommodating the locking member 213 should be provided at the corresponding position of the handle 12 to ensure that the above-mentioned action can be carried out normally.

[0045] Reference Figure 5 and Figure 6 The limiting mechanism 2 further includes a second limiting component 22, which includes an elastic fastener 221 and a fastening groove formed on the mating surface of the handle 12 and the sliding cover 15, wherein the elastic fastener 221 is integrally connected to the handle 12, and the fastening groove is provided on the surface of the sliding cover 15. Further, the elastic fastener 221 is located in the middle of the receiving groove 14 and below the mechanical lock hole 13, and the fastening groove is formed at the top of the sliding cover 15, so that when the sliding cover 15 slides downward, the fastening groove continuously approaches the elastic fastener 221, and finally the elastic fastener 221 is clamped in the fastening groove, at which time the sliding cover 15 has slid to below the mechanical lock hole 13, and the mechanical lock hole 13 is in an exposed state.

[0046] Furthermore, an avoidance groove 151 is provided on the side of the sliding cover 15 facing the handle 12, and the avoidance groove 151 extends along the height direction of the sliding cover 15. A locking protrusion 152 is provided at the top of the avoidance groove 151. The buckle groove is formed on the side of the locking protrusion 152 away from the avoidance groove 151, and the buckle groove and the avoidance groove 151 are located on the same straight line.

[0047] By setting the avoidance groove 151, initially, the elastic fastener 221 partially extends into the avoidance groove 151 to prevent it from being squeezed by external force. In the process of sliding the sliding cover 15 downward, the elastic fastener 221 slides relatively in the avoidance groove 151, and when it approaches the locking protrusion 152, it is squeezed by the locking protrusion 152 and enters the buckle groove. At this time, the sliding cover 15 cannot slide further downward, thereby achieving the limitation of the position of the sliding cover 15.

[0048] It can be understood that when the elastic fastener 221 is matched with the buckle groove, the two roughly have two matching surfaces, and the two matching surfaces are distributed up and down. In order to enable the sliding cover 15 to slide upward in this state, the matching surfaces of the two located below can be set to be inclined. When an upward thrust is applied to the sliding cover 15, the elastic fastener 221 can be deformed along the inclined matching surface and disengaged from the buckle groove.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
