Description

Technical Field

[0001] The invention relates to an electronic door lock, in particular to a full-automatic integrated lock. Background Art

[0002] Electronic door locks are smart door locks that are more secure and convenient than traditional mechanical door locks. They mainly use electronic technology to unlock the door. Common unlocking methods include fingerprint recognition, password input, card swiping, and mobile phone APP control. Electronic door locks also have functions such as automatic alarm and unlocking record recording. Some also support remote authorization unlocking. They have diverse appearance designs and can be adapted to various door types. They are widely used in homes, offices, hotels and other places, bringing great convenience to people's lives and work.

[0003] In today's electronic lock design, the layout planning of the lock body's internal space is a key issue. Electronic locks usually have three driving modes: motor drive, key drive, and handle drive. However, due to the limited internal space of the lock body, it can often only accommodate two of the above three. This means that when designing, you must weigh the pros and cons between different driving modes. For example, choosing motor drive and key drive can meet the needs of electronic unlocking and emergency mechanical unlocking, but may sacrifice the convenience of handle drive; if you choose motor drive and handle drive, daily operation is convenient, but there is a lack of emergency protection of key drive. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an electronic lock that can achieve unlocking and locking in three driving modes.

[0005] To achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a fully automatic one-piece lock, comprising a lock body and a plurality of lock tongues telescopically arranged in the lock body and arranged toward the door frame, a plurality of mounting holes matched with the door frame to form a fixed position therebetween are arranged on the outer surface of the lock body, the lock tongue comprises an oblique tongue and a square tongue, a lock core hole matched with a mechanical key and a square column lock block matched with a handle are arranged on the lock body, an electric drive transmission device and a mechanical drive transmission device driven by a motor are arranged inside the lock body, the mechanical drive transmission device can be driven by the mechanical key inserted into the lock core hole and can be driven by the handle inserted into the square column lock block, the telescopic movement of the plurality of square tongues are all driven by the same square tongue driving plate, and the square tongue driving plate drives the plurality of square tongues to extend or retract at the same time during the process of moving up and down, the electric drive transmission device and the mechanical drive transmission device can independently drive the square tongue driving plate to move up and down, and the electric drive transmission device and the mechanical drive transmission device are respectively provided with an electric drive oblique tongue driving plate and a mechanical drive oblique tongue driving plate for driving the oblique tongue to extend or retract.

[0006] The beneficial effects of the present invention are as follows: this fully automatic one-piece lock has many significant beneficial effects. First, it has three driving modes: motor drive, mechanical key drive, and handle drive, which allows users to have more choices when unlocking and locking. Whether it is the convenience of daily electronic unlocking, or the reliability of mechanical key unlocking in emergencies, or the directness of handle operation, it can meet the needs of different scenarios and users. Secondly, its key drive and handle drive share a set of mechanical drive transmission devices, which greatly saves the internal space of the lock body and effectively solves the problem of limited internal space of the lock body. At the same time, multiple square tongues are driven by the same square tongue drive plate and can be extended or retracted synchronously, ensuring the stability and safety of the lock. In addition, the electric drive transmission device and the mechanical drive transmission device are respectively provided with independent oblique tongue drive plates to ensure that the telescopic movement of the oblique tongue is accurate and reliable, further improving the practicality and reliability of the product.

[0007] Furthermore, the number of square tongues is two, and the number of inclined tongues is one; the electric drive transmission device and the mechanical drive transmission device both include an inclined tongue driving mechanism for driving the extension and retraction of the inclined tongue and a square tongue driving mechanism for driving each square tongue; a card plate is provided on the inclined tongue, and an electric-driven inclined tongue driving plate is provided on the end of the card plate facing the electric drive transmission device, and a mechanical-driven inclined tongue driving plate is provided on the end of the card plate facing the mechanical drive transmission device; a slide groove extending in a vertical direction is provided on the square tongue driving plate, and a limiting column inserted into the above-mentioned slide groove is provided on the lock body so that the square tongue driving plate can only move in the up and down directions.

[0008] The structural design of this door lock has many advantages. Clearly defining the number of two square tongues and one oblique tongue can better balance the safety and operational convenience of the door lock. Both the electric drive and mechanical drive transmission devices are equipped with oblique tongue and square tongue drive mechanisms, ensuring that all parts of the door lock can work normally regardless of the drive mode. The coordination of the upper clamping plate of the oblique tongue with the electric drive and mechanical drive oblique tongue drive plates realizes the effective control of the oblique tongue by the two drive modes and improves the reliability of the system. The design of the slide groove on the square tongue drive plate and the lock body limit column enables the square tongue drive plate to move accurately only in the up and down directions, ensuring the stability and accuracy of the square tongue extension and retraction action. It also facilitates clear judgment of the operating status of the square tongue drive part during maintenance, reducing the difficulty of maintenance.

[0009] Furthermore, the electric drive transmission device includes an output tooth connected to the output end of the motor, and the other side of the output tooth is meshed with an inclined tongue driving mechanism. The inclined tongue driving mechanism includes meshing teeth and an inclined tongue active plate arranged in sequence from the end face provided with the mechanical drive transmission device toward the end face provided with the electric drive transmission device. A synchronization shaft for making the above two rotate synchronously is arranged at the center of the meshing teeth and the inclined tongue driving plate. The inclined tongue driving plate and the electrically driven inclined tongue driving plate both include parallel straight plate portions so that when the inclined tongue driving plate rotates, the straight plate portions abut against each other to drive the electrically driven inclined tongue driving plate to rotate and then drive the inclined tongue to extend and retract.

[0010] The structural design of the electric drive transmission device brings many benefits. The output teeth are connected to the output end of the motor, which can efficiently transmit the motor power and ensure the timeliness of the drive. The meshing teeth and the active plate of the inclined tongue in the inclined tongue drive mechanism rotate synchronously through the synchronous shaft, ensuring the stability and continuity of power transmission and making the inclined tongue drive action smooth. The straight plate parts of the inclined tongue drive plate and the electric-driven inclined tongue drive plate cooperate with each other, and can accurately drive the electric-driven inclined tongue drive plate when the inclined tongue drive plate rotates, thereby realizing the stable extension and retraction action of the inclined tongue and improving the reliability of the inclined tongue. In addition, this clear transmission structure allows maintenance personnel to quickly understand and troubleshoot faults during maintenance, reducing the difficulty and time cost of maintenance.

[0011] Furthermore, the square tongue driving mechanism of the electric drive transmission device includes a follower tooth arranged between the meshing tooth and the oblique tongue active plate, a square tongue active plate arranged at the square column lock block, a transmission tooth located between the above two for forming a transmission match, and a square tongue passive plate cooperating with the square tongue active plate for driving the square tongue driving plate to move up and down, the synchronization shaft is passed through the center of the follower tooth and drives the follower tooth to rotate synchronously with the oblique tongue active driving plate and the meshing tooth, the square tongue active plate is provided with a notch for the square tongue passive plate to move therein, the square tongue active plate abuts against the square tongue passive plate during rotation so that the square tongue passive plate rotates with the center of the square tongue active plate as the axis, and the other end of the square tongue passive plate is placed in the square tongue driving plate so that the square tongue driving plate generates a movement trend.

[0012] The square tongue drive mechanism of the electric drive transmission device is reasonably designed and practical. The arrangement of follower teeth, transmission teeth and other components constructs a stable transmission chain, ensuring that power is efficiently and stably transmitted from the motor to the square tongue drive plate, ensuring that the extension and retraction of the square tongue is powerful and stable. The unique matching mode of the square tongue active plate and the square tongue passive plate, such as the notch design and the mode of rotating against each other, can accurately control the movement trend of the square tongue drive plate, making the extension and retraction of the square tongue more accurate and controllable. At the same time, this clear transmission structure layout enables maintenance personnel to quickly sort out the transmission path and accurately find the fault point during the maintenance process, which greatly reduces the difficulty of maintenance, shortens the maintenance time, and improves the maintenance efficiency.

[0013] Furthermore, the oblique tongue driving mechanism of the electric drive transmission device also includes a planetary gear set arranged between the meshing teeth and the follower teeth, the planetary gear set includes a rotating shell, a plurality of rotating teeth meshed on the peripheral side of the meshing teeth and driven thereby are arranged in the rotating shell, and the plurality of rotating teeth are all sleeved on the synchronous shaft to drive the synchronous shaft to rotate, the inner diameter surface of the rotating shell is meshed with the rotating teeth, and the outer diameter surface of the rotating shell is circumferentially provided with a plurality of meshing parts, one end of the clutch rod is clamped between adjacent meshing parts for fixing the rotating shell so as to drive the synchronous shaft to rotate through the rotating teeth when the meshing teeth rotate; the clutch rod causes the clutch rod to move toward an elastic member of one end clamped between the meshing parts.

[0014] The latch bolt drive mechanism of the electric drive transmission device has many significant advantages. The planetary gear set is cleverly placed between the meshing teeth and the follower teeth. This layout is ingenious. Multiple rotating teeth are closely meshed on the meshing teeth circumferential side, and the power transmission is efficient and orderly. It can accurately drive the synchronous shaft to rotate, provide stable and accurate power support for the latch bolt drive, and ensure the accuracy and stability of the latch bolt movement. A good coordination mechanism is formed between the rotating housing, the rotating teeth and the clutch rod, which greatly enhances the flexibility and controllability during the power transmission process. When one end of the clutch rod is inserted into the fixed rotating housing between the adjacent meshing parts, the rotation of the meshing teeth can smoothly drive the synchronous shaft through the rotating teeth, which effectively guarantees the accuracy of the latch bolt drive. It is worth mentioning that the elastic member provided on the clutch rod prompts the clutch rod to move toward one end of the meshing parts. The elastic member not only plays a role in stabilizing the position of the clutch rod, but also plays a buffering role during the operation of the mechanism, effectively reducing the friction and impact between the components, thereby improving the stability and reliability of the entire latch bolt drive mechanism, extending the service life of the mechanism, and comprehensively improving the product performance.

[0015] Furthermore, a handle can be inserted into the center of the square column lock block to enable the square column lock block to rotate, and the square tongue driving mechanism of the mechanical drive transmission device includes a locking / unlocking driving plate which is sleeved on the circumference of the square column lock block and rotates therewith when the square column lock block rotates, and the locking / unlocking driving plate is respectively hinged with an unlocking plate and a locking plate at positions on the left and right sides of the square column lock block, and the unlocking plate and the locking plate are provided with a linkage plate at one end away from the square column lock block, and the rotation point of the linkage plate is set on a certain square tongue, and its two ends are respectively arranged on the unlocking plate and the locking plate to ensure that when one of the unlocking plate and the locking plate rises, the other will fall synchronously; the square column lock block is also provided with a first tripping plate which abuts against the back of the square tongue passive plate and rotates with the square column lock block, one end of the first tripping plate abuts against the clutch rod and drives the clutch rod to disengage between the meshing parts of the rotating shell when the square column lock block rotates, so that the rotating shell is in a rotatable state.

[0016] The relevant structure of the mechanical drive transmission device shows many practical and excellent beneficial effects. First, the handle can be inserted into the center of the square column lock block and rotated. This design makes the user's operation extremely convenient and can easily realize the mechanical control of the lock. The locking / unlocking drive plate is sleeved on the circumference of the square column lock block and rotates with it (it can be clamped on the outer surface of the cylindrical square column lock block through the inner diameter surface of the locking / unlocking drive plate to realize the transmission between the two). At the same time, through the clever cooperation of the hinged unlocking plate and the locking plate and the linkage plate, the synchronous reverse movement of the two is realized, ensuring that the action is coherent and efficient during the unlocking or locking operation, greatly improving the reliability and stability of the mechanical drive. Furthermore, the first release plate arranged at the square column lock block not only rotates with the square column lock block, but also drives the clutch rod to disengage the meshing part of the rotating shell when rotating, so that the rotating shell enters a rotatable state, so that during the unlocking or locking process of the mechanical drive transmission device, the rotation of the rotating teeth can be transferred to the rotating shell, and then the transmission will not be applied to the output end of the motor through the output teeth, so as to ensure that the motor will not be damaged.

[0017] Furthermore, the locking plate is a latch bolt driving mechanism of a mechanically driven transmission device, and the locking plate abuts against the mechanically driven latch bolt driving plate on the side facing the mechanically driven transmission device at one end away from the linkage plate, and abuts against the square bolt passive plate on the side facing the electric drive transmission device, so that when the locking plate descends, the square bolt driving plate is driven to descend and the mechanically driven latch bolt driving plate is driven to retract.

[0018] This unique structural design of the locking plate brings many benefits. Through the clever abutment layout with the mechanically driven oblique tongue drive plate and the square tongue passive plate, when the locking plate descends, it can simultaneously drive the square tongue drive plate to descend and drive the mechanically driven oblique tongue drive plate to retract the oblique tongue, thereby achieving efficient linkage of the square tongue and oblique tongue movements, simplifying the operating process, and improving the convenience of unlocking for users. In terms of safety, this integrated drive design makes the locking and unlocking process of the door lock more consistent and stable, reducing the risk of failure that may arise from the independent operation of components. From a maintenance perspective, the structure has clear logic, and maintenance personnel can quickly determine the location and cause of the failure based on this clear transmission relationship, so as to carry out targeted maintenance, which significantly improves the efficiency and accuracy of maintenance.

[0019] Furthermore, it also includes a second tripping plate, which is rotatably arranged on a square tongue provided with a linkage plate, and is arranged corresponding to the unlocking plate and the locking plate. The second tripping plate abuts against the clutch rod and drives the clutch rod to disengage from the meshing part of the rotating shell when the key is inserted and rotated; abutment platforms are arranged at corresponding positions of the second tripping plate, the unlocking plate and the locking plate, and the abutment platforms cooperate with the convex points on the lock core to drive the above three to rotate.

[0020] These newly added structures further enrich and enhance the advantages of the mechanical drive transmission device. The second trip plate is rotatably arranged on the square tongue provided with the linkage plate, and is arranged correspondingly to the unlocking plate and the locking plate, and can drive the clutch rod to disengage the meshing portion of the rotating shell when the key is inserted and rotated. This design greatly enhances the functionality and convenience of key operation. The user can easily switch between electric drive and mechanical drive by turning the key, providing a reliable guarantee for using the key to unlock in emergency situations. At the same time, the corresponding abutment platforms arranged on the second trip plate, the unlocking plate and the locking plate cooperate with the convex points on the lock core, and can accurately drive the three to rotate when the key is turned, ensuring the continuity and stability of the entire mechanical drive system under key operation. This clever cooperation not only improves the reliability of the mechanical drive, but also further optimizes the synergistic relationship between the mechanical drive and the electric drive transmission device, avoids potential conflicts between different drive modes, and comprehensively improves the safety and compatibility of the lock, bringing users a more convenient, safe and stable use experience. Similarly, after the clutch rod is unlocked, the rotating shell enters a rotatable state to ensure that the motor will not be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The linkage components and linkage processes between the electric drive transmission device 3 and the mechanical drive transmission device 4 are described below.

[0031] The electric drive transmission device 3 includes a latch tongue driving mechanism 35 for driving the latch tongue 21 to extend and retract, a latch tongue driving mechanism A31 for driving the first square tongue 22 and the second square tongue 23, and an output tooth 34 meshed with the output end of the motor 33. The other side of the output tooth 34 is meshed with the latch tongue driving mechanism 35. The latch tongue driving mechanism 35 includes a meshing tooth 351 and a latch tongue active plate 352 arranged in sequence from the end face provided with the mechanical drive transmission device 4 to the end face provided with the electric drive transmission device 3. The meshing tooth 35 A synchronization shaft 353 is provided at the center of the oblique tongue driving plate 1 and the oblique tongue driving plate 352 to make the above two rotate synchronously. The oblique tongue driving plate 352 and the electric-driven oblique tongue driving plate 32 both include parallel straight plate portions (the straight plate portion of the oblique tongue driving plate 352 is 3521, and the straight plate portion of the electric-driven oblique tongue driving plate 32 is 321) so that when the oblique tongue driving plate 352 rotates, the straight plate portions abut against each other to drive the electric-driven oblique tongue driving plate 32 to rotate, thereby driving the oblique tongue 21 to extend and retract. The clutch rod 316 is also included. The latch tongue driving mechanism 35 also includes a planetary gear set 315 arranged between the meshing teeth 351 and the follower teeth 311. The planetary gear set 315 includes a rotating housing 3151. A plurality of rotating teeth 3152 meshing with the meshing teeth 351 and driven by the meshing teeth 351 are arranged in the rotating housing 3151. The plurality of rotating teeth 3152 are all sleeved on the synchronous shaft 353 to drive the synchronous shaft 353 to rotate. The inner diameter surface of the rotating housing 3151 is The outer diameter surface of the rotating shell 3151 is meshed with the rotating teeth 3152, and a plurality of meshing portions 31511 are circumferentially arranged. One end of the clutch rod 316 is clamped between adjacent meshing portions 31511 to fix the rotating shell 3151 so as to drive the synchronous shaft 353 to rotate through the rotating teeth 3152 when the meshing teeth 351 rotates. The clutch rod causes the clutch rod 316 to move toward an elastic member 3161 at one end of the clutch rod 316 that is clamped between the meshing portions 31511.

[0032] The square tongue driving mechanism A31 of the electric drive transmission device 3 includes a follower tooth 311 arranged between the meshing tooth 351 and the oblique tongue active plate 352, a square tongue active plate 312 arranged at the square column lock block 12, and a transmission tooth 313 and a square tongue passive plate 314 located between the above two for forming their transmission cooperation. The synchronization shaft 353 is penetrated at the center of the follower tooth 311 and drives the follower tooth 311 to rotate synchronously with the oblique tongue active driving plate 352 and the meshing tooth 351. The square tongue active plate 312 is provided with a notch 3121 for the square tongue passive plate 314 to move therein. The square tongue active plate 312 abuts against the square tongue passive plate 314 during the rotation process, so that the square tongue passive plate 314 rotates with the center of the square tongue active plate 312 as the axis, and the other end of the square tongue passive plate 314 placed in the square tongue driving plate 5 causes the square tongue driving plate 5 to generate a movement trend.

[0033] The unlocking process of the above-mentioned electric drive transmission device 3 is as follows, while the locking process is the opposite, which will not be described in detail here: when the motor 33 rotates, the meshing teeth 351 are driven to rotate through the output teeth 34, and then the synchronous shaft 353 is driven to rotate through the rotating teeth 3152, so that all the parts connected to the synchronous shaft 353 are rotated, and the resulting movement process includes: first, driving the inclined tongue active plate 352 to rotate to abut against the electric drive inclined tongue driving plate 32 to unlock the inclined tongue 21; second, because the clutch rod 316 is stuck in the meshing portion 3151 on the outer peripheral surface of the rotating shell 3151 at this time 1, so the rotating teeth 3152 inside the planetary gear set 315 can drive the synchronous shaft 353 to rotate; at the same time, the transmission teeth 313 drive the square tongue active plate 312 to rotate, and when one end of the notch 3121 abuts against the square tongue passive plate 314, the end of the square tongue passive plate 314 connected to the square tongue driving plate 5 drives the square tongue driving plate 5 to generate a trend of moving along the circumferential direction of the square tongue passive plate 314, and then the upward movement of the square tongue driving plate 5 is formed through the cooperation between the slide groove 51 and the limiting column 11, thereby unlocking the first square tongue 22 and the second square tongue 23.

As a preferred embodiment, a tongue linkage plate 53 is further provided between the tongue driving plate 5 and the first and second tongues 22 and 23 to facilitate the movement of the first and second tongues 22 and 23 in the oblique grooves 52, so as to make the unlocking and locking process smoother.

[0035] The mechanical drive transmission device 4 includes a latch bolt driving mechanism 41 for driving the latch bolt 21 to extend and retract, and a latch bolt driving mechanism B43 for driving the first and second latch bolts 22 and 23. The center of the square column lock block 12 can cooperate with the handle to drive it to rotate. The latch bolt driving mechanism B43 of the mechanical drive transmission device 4 includes a locking / unlocking driving plate 412 that is sleeved on the side of the square column lock block 12 and rotates when the square column lock block 12 rotates. The locking / unlocking driving plate 412 is respectively hinged with an unlocking plate 413 and a locking plate 414 at positions on the left and right sides of the square column lock block 12. The unlocking plate 413 and the locking plate 414 are provided with a linkage plate 415 at one end away from the square column lock block 12. The rotation point of the linkage plate 415 is set on the first latch bolt 22, and its two ends are respectively set on the unlocking plate 413 and the locking plate 414 to ensure that when one of the unlocking plate 413 and the locking plate 414 rises, the other will fall synchronously. The square column lock block 12 is also provided with a first release plate 416 which abuts against the back of the square tongue passive plate 314 and rotates with the square column lock block 12. One end of the first release plate 416 abuts against the clutch rod 316 and drives the clutch rod 316 to disengage from the meshing portion 31511 of the rotating shell 3151 when the square column lock block 12 rotates, thereby making the rotating shell 3151 in a rotatable state.

[0036] The locking plate 414 is the oblique tongue driving mechanism 41 of the mechanical drive transmission device 4. The locking plate 414 abuts against the mechanical drive oblique tongue driving plate 42 on the side facing the mechanical drive transmission device 4 at one end away from the linkage plate 415, and abuts against the square tongue passive plate 314 on the side facing the electric drive transmission device 3, so that when the locking plate 414 descends, the square tongue driving plate 5 is driven to descend and the mechanical drive oblique tongue driving plate 42 is driven to drive the oblique tongue 21 to retract.

[0037] It also includes a second tripping plate 317, which is also rotatably arranged on the first square tongue 22 provided with the linkage plate, and is arranged corresponding to the unlocking plate 413 and the locking plate 414. The second tripping plate 317 abuts against the clutch rod 316 and drives the clutch rod 316 to disengage from the meshing portion 31511 of the rotating shell 3151 when the key is inserted and rotated; abutment platforms 417 are arranged at corresponding positions of the second tripping plate 317, the unlocking plate 413 and the locking plate 414, and the abutment platforms 417 cooperate with the protrusions (not shown in the figure) on the lock core (not shown in the figure) to drive the above three to rotate.

[0038] When driven by the handle, the unlocking process of the mechanical drive transmission device 4 is as follows, while the locking process is the opposite, which will not be described here: when the square column lock block 12 rotates clockwise, the unlocking plate 413 moves upward and the locking plate 414 moves downward, and at this time, the first trip plate 416 drives the clutch rod 316 to release the lock of the rotating housing 3151, so that the rotating housing 3151 is in a rotatable state. When the locking plate 414 moves downward, firstly, it causes the first square tongue 22 to move along the inclined slide groove 52 through the linkage plate 415, and then its other end abuts between the notch 3121 of the square tongue passive plate 314 connecting the square tongue active plate 312 and the square tongue driving plate 5, so that the square tongue passive plate 314 has a counterclockwise rotation trend, and the two cooperate to achieve the purpose of unlocking the first square tongue 22 and the second square tongue 23; at the same time, when the locking plate 414 moves downward, it also drives the mechanical drive oblique tongue driving plate 42 to drive the oblique tongue 21 to retract. Furthermore, since the rotating housing 3151 can absorb the rotation of the rotating teeth 3152, the motor can be protected.

[0039] When driven via the lock core hole as described above, the unlocking process of the mechanical drive transmission device 4 differs from that of the handle drive as follows, while the locking process is the opposite, which will not be described in detail here: when the protrusion (not shown in the figure) on the lock core (not shown in the figure) rotates, it simultaneously drives the locking plate 414 to move downward and drives the second tripping plate 317 to rotate, and then the unlocking and locking operations are performed on the basis of releasing the clutch rod 316 from the lock of the rotating shell 3151.

[0040] The above embodiment is only one of the preferred specific embodiments of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
