Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, and in particular to the shell structure of a touch-sensitive smart lock. Background Technology

[0002] With the advancement of technology, smart locks, with their convenient fingerprint, password and other unlocking methods, have gradually replaced traditional mechanical locks and have been widely used in industrial applications. Existing smart locks integrate sophisticated electronic identification modules, control circuit boards and mechanical lock bodies that perform the unlocking action, providing users with great convenience.

[0003] In the design and development of existing products, designers focus on improving the electronic functions of smart locks, such as pursuing faster recognition speed, larger user storage capacity, or richer IoT linkage functions. Therefore, the design of its shell structure prioritizes aesthetics and simple accommodation of internal electronic components, while relatively little attention is paid to its physical protection performance.

[0004] However, as the first line of defense in industrial applications, door locks not only have to withstand technical attacks but also various physical challenges in actual use. The plastic or ordinary metal shells commonly used at present have limited structural strength when faced with malicious impacts or prying, resulting in deformation or damage. This exposes the internal precision electronic components or mechanical lock cylinders, causing them to lose their due security capabilities. At the same time, long-term exposure to natural environments such as sun and rain causes the shell material to age and corrode, further reducing the overall protective performance and service life. Utility Model Content

[0005] In view of the problems of insufficient structural strength, susceptibility to external force damage and environmental erosion, resulting in low overall physical protection performance of existing touch-sensitive smart lock shell structures, this utility model aims to provide a touch-sensitive smart lock shell structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a touch-sensitive smart lock housing structure, including a lock body; and a smart lock mechanism and a fixing mechanism installed on the lock body.

[0007] The smart lock mechanism includes a fixed shell as its main body, a handle rotatably connected to the outside of the fixed shell, a lock cylinder and a lock tongue integrally disposed at the lower part of the fixed shell, and a battery compartment inside the fixed shell; the smart lock mechanism also includes a touch component, which includes a touch panel integrated on the outer surface of the fixed shell, and an operation panel and a storage panel housed inside the fixed shell; a fixing groove for concealing the lock cylinder is also provided on the fixed shell, and a cover plate is slidably connected to the fixing groove.

[0008] Furthermore, the fixing mechanism includes a protective shell and a positioning plate, which are respectively attached to the left and right sides of the lock body to wrap around it; the protective shell, lock body and positioning plate are fastened together by screws passing through the positioning plate and the lock body and nuts connected to the screw threads; in addition, a connecting plate is fixedly connected to one side of the positioning plate, and a bumper strip is fixedly connected to the end of the connecting plate away from the positioning plate, together forming a complete external protection and buffer system.

[0009] Preferably, the smart lock mechanism further includes a fixing plate, which is detachably fitted onto the opening on the side of the fixing shell facing the lock body, thereby forming a closed cavity that facilitates the installation and maintenance of internal electronic components, improving the convenience of production assembly and subsequent maintenance.

[0010] Preferably, the smart lock mechanism further includes an identification panel, which is disposed on the surface of the fixed shell and electrically connected to the control panel. The identification panel is used to collect the user's biometric information for identity comparison, thereby forming a multi-factor authentication with the password information entered through the touch panel, which improves the security of the door lock.

[0011] Preferably, a retaining ring is provided between the nut and the positioning plate. The retaining ring surrounds the outer circumference of the screw. Its function is to disperse the fastening stress by increasing the contact area, avoid stress concentration that could damage the lock body, and effectively prevent the connection from loosening due to vibration during long-term use, thus ensuring the long-term stability of the installation structure.

[0012] Preferably, a fixing block is provided on one side of the cover plate. The fixing block is used to engage with the inner wall of the fixing groove, thereby reliably locking the cover plate in the closed position, ensuring a stable and reliable effect of hiding and protecting the spare lock cylinder, and preventing its accidental exposure.

[0013] Preferably, the handle is hollow inside and houses a switching mechanism for driving the extension and retraction of the latch. This integrated design cleverly integrates the mechanical transmission structure into the component directly operated by the user, making the overall structure more compact and the appearance simpler.

[0014] Preferably, the anti-collision strip is made of elastic rubber material, and its side facing the door frame is set as an arc surface. This choice of material and shape can produce progressive elastic deformation upon contact, thereby maximizing the absorption of impact energy and providing excellent buffer protection.

[0015] Preferably, the battery compartment is located at the top inside the fixed shell, away from the lower lock cylinder and bolt. This layout aims to physically isolate the power supply from the precision mechanical parts, effectively avoiding the risk of damage to the normal operation of the lock cylinder due to accidental battery leakage or other reasons.

[0016] This utility model has the following beneficial effects: 1. This utility model provides a protective enclosure for the lock body by setting up a fixing mechanism consisting of a protective shell and a positioning plate, and firmly integrating them into one piece using screws and nuts. This solves the problems of the existing smart lock shell structure being simple, lacking physical strength, and being damaged by external impact or human-caused damage. It enhances the overall structural strength of the lock body, improves its impact and damage resistance, and extends its service life.

[0017] 2. This utility model solves the security risks of long-term exposure, technical opening, or blockage of the backup mechanical lock cylinder by setting a sliding cover plate that is locked by a fixed block. This improves the security and concealment of the backup unlocking solution and enhances the overall aesthetics of the product.

[0018] 3. This utility model solves the problem in the prior art where the lock body is directly damaged by violent impact when the door is opened and closed by adding an anti-collision strip fixed by a connecting plate to the fixing mechanism. It effectively buffers the impact force, protects the lock body from vibration damage, and further improves the long-term stability of the door lock. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figures 1 to 4 This utility model provides a touch-sensitive smart lock housing structure, which aims to solve the problems of weak physical protection structure and insufficient overall physical security of smart lock housings in the prior art.

[0023] like Figures 1 to 4 As shown, the touch-sensitive smart lock housing structure includes a lock body 1 as the mounting base, a smart lock mechanism 2 mounted on the lock body 1, and a fixing mechanism 3 for enhancing physical protection; Specifically, the smart lock mechanism 2 includes a fixed shell 201 as the main body, and a handle 202 is mounted on the outside of the fixed shell 201 by a rotatable connection. The lower part of the fixed shell 201 is integrally provided with a traditional mechanical lock cylinder 203 and a bolt 206 for performing locking actions. The top of the interior of the fixed shell 201 is also provided with a battery compartment 2074 for accommodating backup power. The human-computer interaction function of the smart lock mechanism 2 is realized by a touch component 207. The touch component 207 includes a touch panel 2071 integrated on the outer surface of the fixed shell 201, and an operation panel 2072 and a storage panel 2073 housed inside the fixed shell 201. In order to improve the security and concealment of the mechanical lock cylinder 203, a fixing groove 2076 is specially provided on the fixed shell 201, and a cover plate 2075 is provided. The cover plate 2075 and the fixing groove 2076 are slidably connected, so that it can slide left and right to selectively cover or expose the lock cylinder 203. The fixing mechanism 3, as an independent protective unit to enhance the strength of the lock body 1, includes a protective shell 301 and a positioning plate 304. During installation, the protective shell 301 and the positioning plate 304 are respectively attached to the left and right sides of the lock body 1, forming a tight wrap-around protection for the lock body 1. In order to achieve a stable installation, the fixing mechanism 3 also includes a screw 305 and a nut 307. The shank of the screw 305 passes through the positioning plate 304 and the lock body 1 in sequence, and its end is threadedly connected to the nut 307, thereby firmly fastening the fixing mechanism 3 to the lock body 1 together. In addition, in order to buffer the impact force generated when the door closes, the connecting plate 302 is fixedly connected to one side of the positioning plate 304, and the anti-collision strip 303 is fixedly connected to the end of the connecting plate 302 away from the positioning plate 304.

[0024] Please refer to Figure 3 and Figure 4The fixing mechanism 3, as a reinforcing component independent of the smart lock mechanism 2, is mainly composed of a protective shell 301 and a positioning plate 304. The inner surface contours of the protective shell 301 and the positioning plate 304 are adapted to the outer surface contours of the lock body 1, so that they can fit tightly against the left and right sides of the lock body 1 during installation, forming a wrap-around reinforcement structure. The fixing installation is achieved by screws 305 and nuts 307. The shank of the screw 305 passes through the outside of the positioning plate 304 and through the mounting through hole pre-set in the lock body 1. Its threaded end is threadedly connected to the nut 307 set on one side of the protective shell 301. The applied tightening force secures the protective shell 301, the lock body 1, and the fixing mechanism 304. Positioning plate 304 is firmly integrated into a whole; a retaining ring 306 is provided between nut 307 and positioning plate 304. The retaining ring 306 surrounds the outer periphery of screw 305. Its function is to increase the contact area, disperse the fastening stress, and prevent the connection from loosening due to vibration; in order to further improve durability, connecting plate 302 is connected to the outside of positioning plate 304 by welding or screw fixing, and anti-collision strip 303 is fixedly connected to connecting plate 302 by adhesive or snap-fit. This anti-collision strip 303 is made of elastic rubber material, and its side facing the door frame is set as a curved surface, which can provide effective buffering and absorb impact energy when the door is closed.

[0025] Meanwhile, the outer casing of the smart lock mechanism 2 itself has also undergone an ingenious structural design; please refer to... Figure 3 The lower part of the fixed shell 201 has a cavity for accommodating the spare mechanical lock cylinder 203, and a U-shaped fixing groove 2076 is formed on the outside of this cavity; the two sides of the cover plate 2075 are bent inward to form guide rails, which slide in perfect fit with the shape of the fixing groove 2076; a fixing block 2077 is integrally formed on one side of the cover plate 2075. The fixing block 2077 is a small elastic protrusion. When the cover plate 2075 slides to the position that completely covers the lock cylinder 203, the fixing block 2077 will engage with the pre-set recess on the inner wall of the fixing groove 2076. This engaging structure ensures that the cover plate 2075 will not accidentally slide open, thereby providing stable and reliable concealment and protection for the lock cylinder 203.

[0026] As a preferred embodiment, in order to facilitate the installation and maintenance of electronic components such as the internal control panel 2072 and storage panel 2073, the smart lock mechanism 2 also includes a fixing plate 204. The fixing plate 204 is detachably fitted onto the opening on the side of the fixing shell 201 facing the lock body 1 by means of screws or buckles, forming a closed receiving cavity. In a preferred embodiment, in order to achieve multiple verifications of user information, the smart lock mechanism 2 also includes an identification panel 205. The identification panel 205 can be a fingerprint recognition module or a face recognition camera and is embedded in the surface of the fixed shell 201. Its position is adjacent to the touch panel 2071. The identification panel 205 is electrically connected to the control panel 2072 housed inside the fixed shell 201 through a ribbon cable so as to transmit the collected biometric information to the latter for processing and comparison. As a preferred embodiment, in order to realize the unlocking action after successful verification, the handle 202 is set to a hollow structure and houses a switching mechanism for driving the extension and retraction of the bolt 206. When the user holds the handle 202 and presses it down, the switching mechanism will trigger a micro switch, thereby controlling the motor to perform the unlocking action. As a preferred embodiment, in order to optimize the internal layout and isolate the power supply from the precision mechanical structure, the battery compartment 2074 is preferably located at the top of the interior of the fixed shell 201, away from the lower lock cylinder 203 and lock tongue 206, which can effectively prevent damage to mechanical parts due to accidental situations such as battery leakage.

[0027] Working principle: When performing smart unlocking, the user enters password information through the touch panel 2071 on the outside of the fixed shell 201, or registers biometric information such as fingerprints through the recognition panel 205. This information is transmitted to the control panel 2072 and storage panel 2073 inside the fixed shell 201 for comparison and verification. After successful verification, the user presses down on the handle 202 to trigger its internal switching mechanism, which in turn drives the bolt 206 to retract, realizing the door opening action. In an emergency where a mechanical key is needed, the user first slides the cover plate 2075 along the fixing groove 2076 to disengage it from the fixing block 2077, thereby exposing the hidden lock cylinder 203, which can then be unlocked with a key. By firmly integrating the fixing mechanism 3 with the lock body 1, the overall physical strength and resistance to damage are greatly enhanced. During installation, the protective shell 301 and the positioning plate 304 wrap around the lock body 1 from the left and right sides respectively. The screw 305 passes through the positioning plate 304 and the lock body 1, and is then tightened with the nut 307. With the assistance of the fixing ring 306, the three are tightly fixed into a high-strength integrated structure, effectively resisting the direct impact and prying of external forces on the lock body 1. When the door is closed, the anti-collision strip 303 fixed on the connecting plate 302 will preferentially contact the door frame and absorb the impact energy, avoiding direct collision of the lock body 1. Through the synergistic effect of the above structures, this utility model effectively solves the problem of weak physical protection of the outer shell of smart locks and damage from external forces in the prior art, extending the service life of the door lock and improving security.
