Description

Technical Field

[0001] The utility model relates to the field of intelligent door locks, and particularly relates to a structure for avoiding opening a keyhole on the front panel of a full-automatic intelligent lock. Background Art

[0002] Locks are an important part of the access control system. With the continuous development of large-scale integrated circuit technology, sensor technology, and Internet of Things technology, more and more intelligent door locks have evolved on the basis of traditional mechanical locks. For example, intelligent locks with unlocking methods such as fingerprint, password, and facial recognition make the unlocking methods diversified and solve the problem that traditional mechanical locks cannot be opened when the key is forgotten to be carried. Intelligent locks also have many advantages, such as safety, intelligence, diversified unlocking methods, and high-end design sense. Therefore, more and more people choose intelligent locks instead of traditional mechanical locks.

[0003] Existing intelligent locks mainly drive the lock core to rotate through a motor, and then drive the lock body to unlock or lock through the lock core. To ensure the reliability of the use of intelligent locks, a mechanical unlocking mechanism is usually set in intelligent locks to unlock when the intelligent lock runs out of power or fails. When the existing intelligent lock is combined with the mechanical unlocking structure, a design of opening a hole on the panel is adopted, which is convenient for inserting a key to unlock. However, the design of opening a hole on the front panel will greatly reduce the aesthetic degree of the intelligent lock, is not convenient for the setting of the intelligent screen, and has relatively low security. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a structure for avoiding opening a keyhole on the front panel of a full-automatic intelligent lock, which has a simple structure, reliable use, high aesthetic degree, and high anti-theft security.

[0005] To solve the above technical problems, the utility model is solved by the following technical solutions: A structure for avoiding opening a keyhole on the front panel of a full-automatic intelligent lock, including a lock body, a lock core, an electric lock stop mechanism, and a mechanical lock stop mechanism; the lock body can be assembled to the door panel and has a retractable lock tongue; the lock core is inserted on the lock body, and a dial is rotatably arranged, and the dial is matched with the electric lock stop mechanism or the mechanical lock stop mechanism to drive the lock tongue, and the mechanical lock stop mechanism includes a rotary telescopic component and a vertical driving component; when unlocking manually, the vertical driving component is used to drive the rotary telescopic component to rotate, and the rotary telescopic component can rotate and translate horizontally and drive the dial to rotate.

[0006] Preferably, the rotary telescopic assembly includes a first unlocking member that can be inserted into the dial wheel. The vertical driving assembly includes a vertical driving rod and a mechanical lock. The vertical driving rod is linked with the rotary telescopic assembly to drive the first unlocking member to move horizontally and rotate. The mechanical lock is used to drive the vertical driving rod to rotate. When the mechanical locking mechanism is unlocked, the rotary telescopic assembly drives the first unlocking member to be inserted into the dial wheel and drives the dial wheel to rotate. The horizontal rotation driven by the rotary telescopic assembly can drive the first unlocking member to move horizontally and rotate into the dial wheel, ensuring the reliability of unlocking or locking the lock body.

[0007] Preferably, the rotary telescopic assembly includes a horizontal driving rod, a driving sleeve, a telescopic member, and a rotating sleeve. The driving sleeve and the rotating sleeve are both rotatably arranged in the lock core. The horizontal driving rod is coaxially connected to the driving sleeve. The driving sleeve is provided with a spiral hole. One end of the telescopic member is rotatably arranged in the driving sleeve and is provided with a fixing column that matches the spiral hole. The other end of the telescopic member is provided with a pressing member. The pressing member is movably inserted into the interior of the rotating sleeve to press the first unlocking member. The first unlocking member is provided with a first limiting portion. The rotating sleeve is provided with a sliding groove corresponding to the first limiting portion. The dial wheel is provided with a limiting groove corresponding to the first limiting portion. The first limiting portion can move along the sliding groove and be inserted into the limiting groove. The advantage is that through the cooperation of the horizontally arranged driving rod, driving sleeve, telescopic member, and rotating sleeve, the first unlocking member can be reliably pushed into the limiting groove. Thus, when the rotary telescopic assembly continues to rotate, the dial wheel can be driven to rotate to operate the lock body, driving the lock tongue to extend and retract, ensuring the reliability of use.

[0008] Furthermore, a first compression spring is arranged in the driving sleeve. The first compression spring is used to compress the telescopic member. The advantage is that the stability of the telescopic member in the driving sleeve can be ensured by the arranged first compression spring, that is, when the driving sleeve rotates, the telescopic member can be reliably and stably driven to expand and contract.

[0009] Symmetrically arranged spiral holes are formed on both sides of the driving sleeve. Two telescopic members are arranged side by side along the axial direction of the driving sleeve. The two telescopic members are combined into a cylindrical shape. Both telescopic members are provided with fixing columns that match the corresponding spiral holes. The other ends of both telescopic members are provided with pressing members. The advantage is that mechanical unlocking can be achieved for both forward and reverse rotations of the vertical driving assembly through the spiral holes arranged on both sides of the rotating sleeve and the two telescopic members, effectively solving the problem of inconsistent rotation directions for unlocking left and right doors and improving adaptability.

[0010] Furthermore, the electric locking mechanism includes a reduction motor, the output shaft of the reduction motor is connected with a rotating rod, a fixed sleeve is arranged on the rotating rod, a second unlocking member is movably arranged in the fixed sleeve, the second unlocking member is provided with a second limiting portion corresponding to the limiting groove, the fixed sleeve is axially provided with a positioning groove matching with the second limiting portion, and a second pressing spring for pressing the second limiting portion into the limiting groove is further arranged in the fixed sleeve; the advantage is that the cooperation of the reduction motor and the rotating rod can drive the second unlocking member to rotate the rod. Since the second limiting portion is matched with the limiting groove under the action of the second pressing spring, the reduction motor can reliably drive the wave wheel to rotate during operation to perform the unlocking or locking action of the lock body.

[0011] Furthermore, a fixing plate is arranged in the dial, the limiting groove is opened on the fixing plate, the second unlocking member is coaxially provided with a fixing rod, the fixing rod penetrates through the fixing plate and extends into the rotating sleeve, and the first unlocking member can be driven to be sleeved outside the fixing rod; the advantage is that the stability of the second unlocking member driving the dialing material to rotate can be ensured by the arranged fixing plate, and at the same time, it can also play the role of the rotating shaft of the first unlocking member, thereby effectively reducing the space occupied by parts, improving the space utilization rate, and ensuring the coaxiality of the first unlocking member and the second unlocking member.

[0012] Furthermore, a first bevel gear is arranged at the other end of the transverse driving rod, and the vertical driving rod is provided with a second bevel gear meshing with the first bevel gear; the advantage is that the cooperation of the first bevel gear and the second bevel gear can realize the transformation of the unlocking direction of the intelligent lock and ensure the rotation synchronism during unlocking.

[0013] Furthermore, the first bevel gear is coaxially provided with an inserting rod, a connecting groove is arranged at one end of the inserting rod close to the transverse driving rod, and the transverse driving rod is hinged in the connecting groove; the advantage is that the adaptability of the transverse driving rod can be improved by the hinged cooperation of the transverse driving rod and the inserting rod.

[0014] Furthermore, the transverse driving rod is plate-shaped, the driving sleeve is provided with a slot corresponding to the transverse driving rod, and the transverse driving rod is inserted into the slot; the advantage is that the arranged slot can facilitate the insertion of the transverse driving rod into the driving sleeve. Thus, during processing and production, the driving sleeve can be integrated into the lock core. When it needs to be assembled on the door panel for use, only the transverse driving rod matched with the first bevel gear needs to be inserted, and it is convenient for the operator to adjust the length of the transverse driving rod to adapt to door panels of different thicknesses.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the electric opening or locking of the intelligent lock can be realized through the motor locking mechanism; the mechanical locking mechanism can realize the manual key opening or locking of the intelligent lock. Through the cooperation of the rotating and telescoping component and the vertical driving component of the mechanical locking mechanism, while realizing the manual mechanical unlocking or locking, the lock hole position for mechanical unlocking can be set on a non-panel, so as to ensure the integrity and aesthetics of the intelligent lock panel, that is, the lock hole position is opened at the lower position of the intelligent lock, improving the concealment of the lock hole and the security of the intelligent lock.

[0027] As shown in the attached Figure 1-7 A structure for avoiding opening a keyhole on the front panel of a full-automatic intelligent lock, including a lock body 1, a lock core 2, an electric lock stop mechanism 6 and a mechanical lock stop mechanism; the lock body 1 can be assembled to a door panel and has a retractable lock tongue 1.1; the lock core 2 is inserted into the lock body 1 and is rotatably provided with a dial 3. The dial 3 cooperates with the electric lock stop mechanism 6 or the mechanical lock stop mechanism to drive the retraction and extension of the lock tongue 1.1. The mechanical lock stop mechanism includes a rotary telescopic component 4 and a vertical driving component 5. The vertical driving component 5 is used to drive the rotary telescopic component 4 to rotate. The rotary telescopic component 4 can move horizontally while rotating, and then drive the dial to rotate. Specifically, the rotary telescopic component 4 includes a first unlocking member 4.4 that can be inserted into the dial 3. The vertical driving component 5 includes a vertical driving rod 5.1, a mechanical lock 5.3 and a horizontal driving rod 5.4. When the vertical driving rod 5.1 rotates, it drives the horizontal driving rod 5.4. The horizontal driving 5.4 is linked with the rotary telescopic component to drive the first unlocking member 4.4 to move horizontally and rotate. The mechanical lock 5.3 is used to drive the vertical driving rod 5.1 to rotate; when unlocking through the mechanical lock stop mechanism, the rotary telescopic component 4 drives the first unlocking member 4.4 to insert into the dial 3 and drives the dial 3 to rotate, thereby driving the retraction and extension of the lock tongue 1.1.

[0028] By default, the electric lock stop mechanism is used to achieve the electric opening or locking of the intelligent lock; when manual unlocking is required, the set mechanical lock stop mechanism can achieve the manual opening or locking of the intelligent lock. And through the cooperation of the rotary telescopic component 4 and the vertical driving component 5 of the mechanical lock stop mechanism, while achieving manual mechanical unlocking or locking, the lock hole position for mechanical unlocking can be set on the non-panel, thereby ensuring the integrity and aesthetics of the intelligent lock panel, that is, opening the lock hole position at the lower position of the intelligent lock, improving the concealment of the lock hole and the security of the intelligent lock, as shown in the attached Figure 1 shown.

[0029] On the basis described above, the rotary telescopic assembly 4 further includes a driving sleeve 4.1, a telescopic member 4.2 and a rotating sleeve 4.3. The driving sleeve 4.1 and the rotating sleeve 4.3 are both rotatably arranged in the lock core 2. The transverse driving rod 5.4 is coaxially connected to the driving sleeve 4.1. The driving sleeve 4.1 is provided with a spiral hole 4.11. One end of the telescopic member 4.2 is rotatably arranged in the driving sleeve 4.1 and is provided with a fixing column 4.21 that cooperates with the spiral hole 4.11. The other end of the telescopic member 4.2 is provided with a pressing member 4.22. The pressing member 4.22 is movably inserted into the rotating sleeve 4.3 for pressing the first unlocking member 4.4. The first unlocking member 4.4 is provided with a first limiting portion 4.41. The rotating sleeve 4.3 is provided with a sliding groove 4.31 corresponding to the first limiting portion 4.41. The dial 3 is provided with a limiting groove 3.2 corresponding to the first limiting portion 4.41. The first limiting portion 4.41 can move along the sliding groove 4.31 and be inserted into the limiting groove 3.2. And a first pressing spring 4.5 is arranged in the driving sleeve 4.1. The first pressing spring 4.5 is used for pressing the telescopic member 4.2. Through the cooperation of the transverse driving rod 5.4, the driving sleeve 4.1, the telescopic member 4.2 and the rotating sleeve 4.3, the first unlocking member 4.4 can be reliably pushed into the limiting groove 3.2. Thus, when the rotary telescopic assembly 4 continues to rotate, the wave wheel can be driven to operate on the lock body 1, driving the lock tongue 1.1 to stretch, ensuring the reliability of use. And the first pressing spring 4.5 can ensure the stability of the telescopic member 4.2 in the driving sleeve 4.1, that is, when the driving sleeve 4.1 rotates, the telescopic member 4.2 can be reliably and stably driven to stretch and contract.

[0030] In a preferred embodiment, spiral holes 4.11 are provided on both sides of the driving sleeve 4.1 of the present design, and the two spiral holes 4.11 are symmetrically arranged about the axis of the driving sleeve 4.1. Two telescopic members 4.2 are arranged side by side along the axial direction in the driving sleeve 4.1. The two telescopic members 4.2 are combined into a cylindrical shape. Both telescopic members 4.2 are provided with fixing columns 4.21 that cooperate with the corresponding spiral holes 4.11. The other ends of the two telescopic members are both provided with pressing members. The cooperation of the spiral holes provided on both sides of the rotating sleeve and the two telescopic members can achieve mechanical locking or unlocking for both forward and reverse rotations of the vertical driving assembly, effectively solving the problem that the unlocking rotation directions of the left and right doors are inconsistent and improving the adaptability.

[0031] On the basis described above, the electric locking mechanism 6 includes a reduction motor 6.1. The output shaft of the reduction motor 6.1 is connected to a rotating rod 6.2. A fixed sleeve 6.3 is arranged on the rotating rod 6.2. A second unlocking member 6.4 is movably arranged in the fixed sleeve 6.3. The second unlocking member 6.4 is provided with a second limiting portion 6.41 corresponding to the limiting groove 3.2. The fixed sleeve 6.3 is provided with a positioning groove 6.31 along its axial direction for cooperating with the second limiting portion 6.41. A second pressing spring 6.5 for pressing the second limiting portion 6.41 into the limiting groove 3.2 is further arranged in the fixed sleeve 6.3. The cooperation between the reduction motor 6.1 and the rotating rod 6.2 can drive the second unlocking member 6.4 to rotate with the rotating rod 6.2. Since the second unlocking member 6.4 makes the second limiting portion 6.41 cooperate with the limiting groove 3.2 under the action of the second pressing spring 6.5, the reduction motor 6.1 can reliably drive the wave wheel to rotate during operation to perform the unlocking or locking action of the lock body 1.

[0032] It is worth mentioning that on the basis described above, a fixing plate 3.1 is arranged in the dial 3. The limiting groove 3.2 is opened on the fixing plate 3.1. The second unlocking member 6.4 is coaxially provided with a fixing rod 6.42. The fixing rod 6.42 penetrates through the fixing plate 3.1 and extends into the rotating sleeve 4.3. The first unlocking member 4.4 can drive the sleeve 4.1 to be arranged outside the fixing rod 6.42. The fixing plate 3.1 can ensure the stability of the second unlocking member 6.4 driving the dialing to rotate. At the same time, it can also act as the rotating shaft of the first unlocking member 4.4, thereby effectively reducing the space occupied by components, improving the space utilization rate, and ensuring the coaxiality of the first unlocking member 4.4 and the second unlocking member 6.4. The arranged limiting plate 4.32 can prevent the lateral slipping of the second unlocking member 6.4 and ensure the working reliability of the electric locking mechanism 6.

[0033] To ensure the reliable direction change of the mechanical lock 5.3 stop structure, that is, to change the insertion direction of the mechanical key, a first bevel gear 5.5 is arranged at the other end of the lateral driving rod 5.4. The vertical driving rod 5.1 is provided with a second bevel gear 5.2 meshing with the first bevel gear 5.5. Through the cooperation of the first bevel gear 5.5 and the second bevel gear 5.2, the unlocking direction of the intelligent lock can be changed, and the rotation synchronism during unlocking can be ensured. Of course, the cooperation of an end face gear and a conventional gear can also be used for driving.

[0034] On the basis described above, the first bevel gear 5.5 of this design is coaxially provided with an inserting rod 5.6. A connecting groove 5.61 is arranged at one end of the inserting rod 5.6 close to the lateral driving rod 5.4. The lateral driving rod 5.4 is hinged in the connecting groove 5.61. The hinged cooperation between the lateral driving rod 5.4 and the inserting rod 5.6 can improve the adaptability of the lateral driving rod 5.4.

[0035] The specific unlocking working process is as follows: When the mechanical key 7 is rotated forward, the mechanical lock 5.3 is rotated through the mechanical key 7, and then the vertical driving rod 5.1 rotates synchronously. The vertical driving rod 5.1 drives the horizontal driving rod 5.4 to rotate through the cooperation of the second bevel gear 5.2 and the first bevel gear 5.5. At this time, the horizontal driving rod 5.4 drives the driving sleeve 4.1 to rotate synchronously. In the initial rotation stage of the driving sleeve 4.1, the telescopic member 4.2 is driven to extend through the spiral hole 4.11, and extends into the rotating sleeve 4.3 to press the fixing rod 6.42, forcing the second unlocking member 6.4 to contract into the fixing sleeve 6.3. At the same time, the first limiting portion 4.41 of the first unlocking member 4.4 is inserted into the limiting groove 3.2 of the dial 3. Continuing to rotate the mechanical key, the horizontal driving rod 5.4 continues to rotate. At this time, the driving sleeve 4.1 drives the telescopic member 4.2 and the rotating sleeve 4.3 to rotate simultaneously. Since the first unlocking member 4.4 is arranged in the sliding groove 4.31, the first unlocking member 4.4 can be driven to continue rotating through the sliding groove 4.31, thereby driving the dial 3 to rotate forward, and then driving the locking tongue 1.1 to act. When the mechanical key 7 is rotated reversely, the vertical driving rod 5.1 drives the horizontal driving rod 5.4 to rotate reversely, and then the driving sleeve 4.1 rotates reversely. The telescopic member 4.2 drives the rotating sleeve 4.3 and the first unlocking member 4.4 to rotate reversely synchronously, so as to ensure the reliable reverse rotation of the dial 3. Then, as the driving sleeve 4.1 rotates reversely, the moving telescopic member 4.2 contracts into the driving sleeve. During this process, the pressing member 4.22 contracts synchronously. During the contraction process of the pressing member 4.22, the first unlocking member 4.4 disengages from the limiting groove 3.2, and the second unlocking member drives the second limiting portion 6.41 to insert into the limiting groove 3.2 under the action of the second pressing spring 6.5, facilitating the electric locking mechanism 6 to drive for electric locking or unlocking.

[0036] It is worth mentioning that the horizontal driving rod 5.4 of this design is plate-shaped, and the driving sleeve 4.1 is provided with a slot 4.12 corresponding to the horizontal driving rod 5.4. The horizontal driving rod 5.4 is inserted into the slot 4.12. The slot 4.12 facilitates the insertion of the horizontal driving rod 5.4 into the driving sleeve 4.1. Thus, during processing and production, the driving sleeve 4.1 can be integrated into the lock core 2. When it needs to be assembled and used on the door panel, only the horizontal driving rod 5.4 that cooperates with the first bevel gear 5.5 needs to be inserted, and it is convenient for the operator to adjust the length of the horizontal driving rod 5.4 to adapt to door panels of different thicknesses.
