[0037] See also Figures 1 to 4 The anti-pinch smart lock 100 of the utility model embodiment includes:

[0038] A front lock body 10, the front side of the front lock body 10 is provided with an input panel 11, the input panel 11 includes a numeric keyboard module 111 and a facial information collection module 112 located above the numeric keyboard module 111; and a rear lock body 20 corresponding to the front lock body 10, the rear lock body 20 includes a mounting seat 21 and a handle 22 disposed on the mounting seat 21, the handle 22 is provided with a control module and a power module electrically connected to the numeric keyboard module 111 and the facial information collection module 112;

[0039] Among them, a hand space 23 is enclosed between the handle 22 and the mounting seat 21, and a removable anti-pinch baffle 24 is covered on one side opening of the hand space 23. The upper and lower ends of the anti-pinch baffle 24 are provided with a snap-fitting portion 241, and the upper and lower ends of the anti-pinch baffle 24 on the handle 22 are provided with a matching portion 224, and the snap-fitting portion 241 is correspondingly snap-fitted with the matching portion 224.

[0040] In the anti-pinch smart lock 100 of the embodiment of the utility model, a clamping portion 241 is provided at the upper and lower ends of the anti-pinch baffle 24, and a matching portion 224 is provided on the first connecting portion 222 and the second connecting portion 223, and the clamping portion 241 is correspondingly engaged with the matching portion 224. Compared with the prior art method of fixing the baffle on the door handle 22 by means of screws, bolts and other structures, the structure of this scheme is simple, and the anti-pinch baffle 24 is also easier to assemble, disassemble and replace.

[0041] For ease of description, the smart lock 100 will be referred to as the anti-finger pinching smart lock 100 hereinafter.

[0042] Since the front lock body 10 is arranged on the front of the door body, the facial information collection module 112 and the numeric keyboard module 111 are arranged on the front of the front lock body 10, so that residents and other people with access rights can enter passwords or facial information through the numeric keyboard module 111 or the facial information collection module 112 to unlock the smart lock 100. The facial information collection module 112 and the numeric keyboard module 111 can constitute an input panel 11, which can be understood as a panel for inputting information, such as inputting digital password information, facial information, and sound information.

[0043] The numeric keypad module 111 may include common numeric keys and other keys such as doorbell keys to implement functions such as password input and doorbell reminder. The specific structure and other functions of the numeric keypad keys can refer to the structure and function of the numeric keypad in the relevant technology, and will not be described in detail here.

[0044] Exemplarily, the facial information acquisition module 112 may include a facial recognition camera, a fill light, an ambient light sensor, and a distance sensor, all of which are electrically connected to the control module. The above components are used to directly or assist in facial recognition acquisition.

[0045] Among them, the face recognition camera can be used to collect face data and transmit it to the control module for face recognition. Of course, the face recognition camera can also be used to shoot outdoor images.

[0046] The ambient light sensor can intervene in the ambient light in the environment where the door is located. Specifically, when the ambient light sensor detects that the current light is weak, in order to prevent the face recognition camera from failing to collect face data completely and clearly, the ambient light sensor can transmit a signal to the control module. The control module can control the fill light to turn on according to the signal to illuminate the face, thereby enabling the face recognition camera to collect face data more completely and clearly, thereby improving the unlocking success rate.

[0047] In one embodiment, the fill light may be an LED light that can emit white light.

[0048] The distance sensor can be used to detect whether a person is approaching. When a person approaches the door and is detected by the distance sensor, the distance sensor can send a signal to the control module, and the control module can control the face recognition camera to turn on. When the use is finished, the control module turns off the face recognition camera. In this way, when some people just pass by and the smart lock 100 does not need to be unlocked, the power consumption of the smart lock 100 can be reduced by turning off the face recognition camera.

[0049] Furthermore, a microphone for collecting and playing sounds can be arranged near the facial information collection module 112. The microphone is electrically connected to the control module. When the facial data of certain visitors is not stored in the control module, the resident can control the microphone to turn on so that the visitor can speak to the resident through the microphone to verify his / her identity. The resident can also actively turn on the microphone to communicate with the visitor, thereby improving the intelligence and diversified functions of the smart lock 100.

[0050] See also Figure 1 A key hole may also be provided on the front lock body 10, and the key hole corresponds to the lock core provided in the door body. A detachable lock core cover 12 may be provided on the front lock body 10 to cover the key hole. Under normal conditions, the lock core cover 12 covers the key hole. In an emergency situation where the door cannot be unlocked by face recognition through the facial information acquisition module 112 or password input through the numeric keypad module 111, the lock core cover 12 may be removed to insert a key into the key hole for mechanical unlocking.

[0051] In some embodiments, the lock core cover 12 may be detachably arranged in a commonly used detachable manner such as snap-fitting, screwing, and gluing, so as to facilitate the removal of the lock core cover 12 when needed.

[0052] Preferably, the lock core cover 12 is detachable on the front lock body 10 in a snap-fitting manner. For example, a snap block can be set on the lock core cover 12, and a corresponding snap hole can be set on the front lock body 10. The lock core cover 12 can be detachably set on the front lock body 10 through the cooperation of the snap block and the snap hole.

[0053] In some embodiments, the lock core cover 12 can be made of materials such as ceramic, metal, glass or acrylic (plastic).

[0054] The rear lock body 20 is arranged on the back of the door body, and a plurality of installation spaces or a plurality of installation structures may be formed therein for installing structures such as control modules and power modules, so as to realize the integrated installation of functional components. The control modules and power modules are arranged in the rear lock body 20, so as to improve the security of the smart lock 100, prevent the smart lock 100 from being maliciously disassembled, modified and invaded, and improve the security of the smart lock 100.

[0055] Specifically, the mounting seat 21 is roughly in the shape of a rectangular flat plate, which can be stably mounted and fixed on the door body in a plane by fasteners such as screws, bolts or rivets, so that the rear lock body 20 can be stably fixed on the door body. The handle 22 can be fixed to the mounting seat 21 by fasteners such as screws and bolts, with a good fastening effect and relatively easy assembly and disassembly. The handle 22 has a gripping portion for the palm of the user to grip, and the gripping portion is spaced from the mounting seat 21 to form a hand space 23, so that the palm of the user can extend into the hand space 23 to grip the handle 22.

[0056] The anti-pinch baffle 24 can be detachably covered on one side of the hand space 23 for closed blocking. When the user's palm extends into the hand space 23 from one side of the rear lock body 20, the anti-pinch baffle 24 seals the other side of the hand space 23 and blocks the user's palm, so that the user's palm will not be too close to the door frame, thereby avoiding the problem of the palm being pinched by the door and ensuring safe use.

[0057] The control module is the control center and data processing center of the smart lock 100, which may include a controller, a memory and a communication module electrically connected to the controller. The controller may be a single chip microcomputer or other components with control and data processing functions, and the memory may store the facial data of people who can pass through. When the facial information acquisition module 112 acquires facial information, the controller may match the acquired facial information with the facial data stored in the memory. When the facial match is successful, the controller may control the smart lock 100 to open.

[0058] The communication module may be a WIFI module to realize the wireless connection function of the smart lock 100. For example, when the resident is not at home and the guest needs to enter the house, the resident can remotely unlock the door through the communication module to avoid the guest being impatient due to waiting for a long time.

[0059] In this embodiment, the power module can be a detachable and rechargeable lithium battery module. When the lithium battery module runs out of power, the resident can remove it for charging. The lithium battery has a strong endurance and a long service life, and can provide effective power support for the smart lock 100 to ensure the normal operation of the smart lock 100.

[0060] In one embodiment, a charging port electrically connected to the power module may also be provided on the rear lock body 20. When the power module is out of power, the power module may be directly charged through the charging port, eliminating the process of disassembling and installing the power module.

[0061] Furthermore, a power detection module can be provided in the control module and electrically connected to the power module to detect the real-time power of the power module. A display module electrically connected to the control module can also be provided on the rear lock body 20 to indicate the real-time power of the power module.

[0062] Exemplarily, the display module can be a structure with display function such as a display light and a display screen. The display light can display a green light or a red light to indicate whether the power module has power or not, respectively, and the display screen can display the power percentage to indicate the power status of the power module.

[0063] In addition, a voice prompt module electrically connected to the control module can be provided on the rear lock body 20. When the power module drops to a certain level, the voice prompt module can issue a voice prompt to remind the resident of the power status of the power module, reminding the resident to replace or charge it in time.

[0064] A cat's eye screen 25 electrically connected to the control module is also provided at the upper portion of the rear lock body 20, and an unlock button 26 electrically connected to the control module is provided below the cat's eye screen 25. When a visitor is photographed by the facial information collection module 112 outdoors, the resident can check through the cat's eye screen 25. If it is confirmed that the visitor can enter, the resident can press the unlock button 26 to unlock the smart lock 100.

[0065] In one embodiment, the basic structures of the front lock body 10 and the rear lock body 20 can be similar. For example, the front lock body 10 can also include a handle structure that is the same as the handle 22 of the rear lock body 20. At the same time, a baffle structure that is the same as the anti-pinch baffle 24 on the rear lock body 20 can also be set on one side of the front lock body 10, so that both the front and back sides of the smart lock 100 have anti-pinch functions, further improving the safety of use of the smart lock 100.

[0066] See also Figures 1 to 4In one embodiment, the handle 22 includes a handle body 221 and a first connection portion 222 and a second connection portion 223 connecting the handle body 221 and the mounting seat 21. The handle body 221 is spaced apart from the mounting seat 21. The first connection portion 222 and the second connection portion 223 are respectively arranged at the relatively upper section and the relatively lower section of the handle body 221. The first connection portion 222, the mounting seat 21, the handle body 221 and the second connection portion 223 form a hand-holding space 23. The matching portion 224 is arranged on the first connection portion 222 and the second connection portion 223.

[0067] The rear lock body 20 in this embodiment is roughly in the shape of a rectangular parallelepiped. If the rear lock body 20 is divided into an upper section and a lower section, the relatively upper section and the relatively lower section of the handle body 221 can be understood as the upper half and the lower half of the rear lock body 20, that is, the first connecting portion 222 is arranged in the upper half of the rear lock body 20, and the second connecting portion 223 is arranged in the lower half of the rear lock body 20.

[0068] The handle body 221 may be generally in the shape of a flat plate and may be held by the palm of a user. The first connection portion 222 and the second connection portion 223 respectively protrude from the upper and lower sections of the handle body 221 toward the mounting seat 21 and are respectively connected to the upper and lower sections of the mounting seat 21. The handle body 221 is spaced apart from the mounting seat 21 by the first connection portion 222 and the second connection portion 223. The first connection portion 222 and the second connection portion 223 may be hollow structures, which can reduce the weight of the handle 22 while connecting the handle body 221 to the mounting seat 21, thereby reducing the weight of the rear lock body 20.

[0069] The first connecting portion 222, the mounting seat 21, the handle body 221 and the second connecting portion 223 form a hand-receiving space 23, into which the user's palm can be inserted to grasp the handle body 221, and the anti-pinch baffle 24 is detachably provided on one side of the hand-receiving space 23 for closing and blocking. When the user's palm extends into the hand-receiving space 23 from one side of the rear lock body 20, the anti-pinch baffle 24 seals the other side of the hand-receiving space 23 and blocks the user's palm, so that the user's palm will not be too close to the door frame, thereby avoiding the problem of the palm being pinched by the door and ensuring safe use.

[0070] See also Figure 3 and Figure 4 In one embodiment, the engaging portion 241 is an arc-shaped protrusion distributed along the width direction of the anti-pinch baffle 24 , and the matching portion 224 is an arc-shaped groove distributed along the thickness direction of the first connecting portion 222 and the second connecting portion 223 .

[0071] Specifically, the engaging portion 241 is an arc-shaped protrusion, and the matching portion 224 is an arc-shaped groove, that is, the shape of the engaging portion 241 is adapted to the shape of the matching portion 224, and the degree of engagement between the two is high, which can improve the stability of the anti-pinch baffle 24 on one side of the hand space 23 when the two are engaged.

[0072] The snap-fitting portion 241 is distributed along the width direction of the anti-pinch baffle 24, and the matching portion 224 is distributed along the thickness direction of the first connecting portion 222 and the second connecting portion 223, that is, the matching portion 224 is distributed along the direction between the handle body 221 and the mounting seat 21. The sizes of the snap-fitting portion 241 and the matching portion 224 formed are large enough to further improve the stability of the two when they are snap-fitted, and further improve the stability of the anti-pinch baffle 24 on one side of the hand space 23.

[0073] More importantly, the surface of the engaging portion 241 is a smooth surface, and the surface of the matching portion 224 is also a smooth surface, which is conducive to the close fit between the surface of the engaging portion 241 and the surface of the matching portion 224, further improving the stability of the anti-pinch baffle 24 on the side of the hand-holding space 23 when the two are matched, and making it easier for the engaging portion 241 and the matching portion 224 to fit together and separate by sliding, which helps to assemble and disassemble the engaging portion 241 and the matching portion 224.

[0074] In one embodiment, the handle body 221 , the first connection portion 222 , the second connection portion 223 and the matching portion 224 are integrally injection molded or integrally cast. The formed handle 22 has better integrity and can simplify the manufacturing process of the handle 22 , thereby improving the production efficiency of the handle 22 .

[0075] Preferably, the handle 22 is made of plastic and is manufactured by integral injection molding, which helps to reduce the weight of the handle 22 and control the manufacturing cost.

[0076] In one embodiment, matching portions 224 are disposed on both sides of the first connection portion 222 and the second connection portion 223 .

[0077] It can be understood that since the door opening is divided into left-opening and right-opening, when the anti-pinch baffle 24 is arranged on one side of the smart lock 100 to prevent the left-opening door from pinching the hand, for the right-opening door, the anti-pinch baffle 24 needs to be moved to the other side of the hand-holding space 23. Therefore, this embodiment provides a matching part 224 on both sides of the first connecting part 222 and the second connecting part 223, so that the user can detachably arrange the anti-pinch baffle 24 on any side of the smart lock 100 according to actual needs to meet different application needs.

[0078] See also Figures 3 to 6In one embodiment, the anti-pinch baffle 24 includes a baffle body 242 and a first extension portion 243 extending from the upper and lower ends of the baffle body 242 toward the hand space 23 , the baffle body 242 covers a side opening of the hand space 23 , and the locking portion 241 is disposed on the outer surface of the first extension portion 243 .

[0079] Specifically, the baffle body 242 is generally in the shape of a flat plate or a thin sheet, and is the main structure for closing and blocking one side of the hand-accommodating space 23. Its shape is adapted to the shape of the openings on both sides of the hand-accommodating space 23, so as to achieve full coverage and closure of one side of the hand-accommodating space 23. Exemplarily, the openings on both sides of the hand-accommodating space 23 can be rectangular, and the baffle body 242 can be in the shape of a rectangular sheet, and the size of the baffle body 242 is slightly smaller than the size of the openings on both sides of the hand-accommodating space 23, so as to ensure that the baffle body 242 can be integrally embedded in the opening of the hand-accommodating space 23 for clamping and fixing.

[0080] In this embodiment, the first extension portion 243 is used to form the locking portion 241, and it is in contact with the surface of the first connection portion 222 and the surface of the second connection portion 223. The outer surface of the first extension portion 243 is the surface where the first extension portion 243 is in contact with the first connection portion 222 and the second connection portion 223.

[0081] The first extension portion 243 has a certain deformation ability. When the anti-pinch baffle 24 is installed on one side of the hand space 23, the two engaging portions 241 are rubbed and squeezed with the first connecting portion 222 and the second connecting portion 223 respectively, so that the corresponding two first extension portions 243 are pressed toward the middle direction of the baffle body 242. After the two engaging portions 241 are correspondingly embedded and engaged with the two corresponding matching portions 224, the two first extension portions 243 can be restored to their original state. At this time, the anti-pinch baffle 24 is firmly installed on one side of the hand space 23.

[0082] Alternatively, after the two engaging portions 241 are correspondingly engaged with the two matching portions 224, the two first extension portions 243 may still be in a certain compressed state, that is, the two first extension portions 243 respectively generate corresponding abutment forces on the first connecting portion 222 and the second connecting portion 223, thereby making the anti-pinch baffle 24 more stable on one side of the hand space 23.

[0083] See also Figure 5 and Figure 6 In one embodiment, at least one side of the baffle body 242 extends toward the hand-holding space 23 to form a second extension portion 244 , and upper and lower ends of the second extension portion 244 are respectively connected to the first extension portions 243 at the upper and lower ends of the baffle body 242 .

[0084] The second extension portion 244 can prevent the baffle body 242 from bending or even folding in the length direction, thereby enhancing the structural strength of the baffle body 242 and further enhancing the overall structural strength of the anti-pinch baffle 24 , thereby extending the service life of the anti-pinch baffle 24 .

[0085] In one embodiment, both sides of the baffle body 242 can extend toward the hand-holding space 23 to form a first extension portion 243 , so as to further enhance the structural strength of the anti-pinch baffle 24 .

[0086] In one embodiment, the baffle body 242 , the first extension portion 243 , the locking portion 241 and the second extension portion 244 are integrally injection molded or cast, that is, the anti-pinch baffle 24 is an integral structure, which can simplify the manufacturing process of the anti-pinch baffle 24 and improve the production efficiency of the handle 22 .

[0087] Preferably, the anti-pinch baffle 24 is made of plastic and can be made by integral injection molding, which helps to reduce the weight of the anti-pinch baffle 24 and control the manufacturing cost. The anti-pinch baffle 24 is easier to deform and is easier to install and remove.
