Description

Technical Field

[0001] This invention relates to the field of electronic lock body technology, specifically to an electronic lock body with directional self-adaptation and over-force protection. Background Technology

[0002] Currently, traditional electronic lock bodies on the market generally suffer from the following defects during production, installation, and use: Lock bodies need to be strictly distinguished by left-opening, right-opening, inward-opening, and outward-opening directions. Production requires classified manufacturing, warehousing requires classified management, and on-site installation requires manual adjustment of the direction. The process is cumbersome, inefficient, and prone to errors. Some lock bodies can still perform deadbolt operation when the door is not closed. When a strong wind suddenly closes the door, the deadbolt tongue will collide hard with the door frame, which can easily cause the internal gears, connecting rods and housing of the lock body to break and be damaged. If the user lifts the handle to lock the lock with excessive force, it will directly cause overload damage to the internal transmission structure, reducing the service life of the lock and its safety.

[0003] To address the aforementioned problems, this invention provides an electronic lock body with adaptive direction and over-force protection, thereby overcoming the shortcomings of the prior art. Summary of the Invention

[0004] The technical problem this invention aims to solve is that traditional electronic lock bodies require distinguishing the door direction and are cumbersome to install and debug; they can be forcibly locked when the door is not closed, which can easily cause collision damage to the lock body; and excessive force is required when lifting the handle to lock, which can cause overload damage to the internal structure of the lock body.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: an electronic lock body with directional self-adaptation and over-force protection, including a lock box, a lock box cover, a side strip and a decorative strip, wherein the lock box cover is closed onto the lock box and is fixed by the lock box cover screw and the threaded sleeve, and the side strip and the decorative strip are fixed to the side of the lock box. It also includes a square latch assembly, a beveled latch assembly, a deadbolt assembly, a pin assembly, an anti-insertion latch assembly, a motor drive assembly, and a circuit board; The latch assembly includes a latch that can swing freely left and right, and the pin assembly includes a pin piece, a pin return piece, a pin piece return spring, and a pin linkage piece. When the latch retracts, the pin linkage piece pushes the pin return piece to extend the pin piece and limit the latch, so as to realize the universal self-adaptive opening direction of the lock body without the need for direction adjustment. The deadbolt assembly includes a deadbolt sliding plate, a deadbolt linkage plate one, and a deadbolt linkage plate two. The deadbolt linkage plate one and the deadbolt linkage plate two are triggered to swing by the extension and retraction position of the latch. When the door is not closed, the deadbolt linkage plate one and the deadbolt linkage plate two block the deadbolt sliding plate from extending. After the door is closed, the restriction is released to allow the deadbolt action.

[0006] As an improvement, the square tongue assembly includes a square tongue, a square tongue bracket, a square tongue moving pin, a square tongue rivet, and a square tongue return spring; The square tongue is hinged to the square tongue bracket by a square tongue rivet, which fixes the square tongue bracket inside the lock box. The square tongue moving pin passes through the square tongue and is connected to the motor drive assembly. One end of the square tongue return spring abuts against the square tongue and the other end abuts against the lock box, realizing the extension and retraction of the square tongue and automatic return.

[0007] As an improvement, the tongue assembly further includes a tongue frame, a tongue switch piece, a tongue spring, a tongue stop, a tongue rod, a handle square shaft lever, a handle square shaft lever ring, and a square shaft lever spring; The latch is installed inside the latch frame, and the latch spring abuts against the latch to achieve elastic extension and retraction. The latch rod connects the latch and the latch switch piece. The handle square shaft toggle block is sleeved on the handle square shaft toggle block ring and is elastically connected to the square shaft toggle block spring. When rotated, it drives the latch rod to extend and retract the latch. The latch baffle is fixedly installed inside the lock box and connected to the latch frame to limit the extension and retraction stroke and swing position of the latch.

[0008] As an improvement, the anti-locking assembly also includes an anti-locking inclined plate, an anti-locking spring plate, a No. 6 gear, and a No. 7 gear; The anti-locking inclined plate abuts against the anti-locking sliding plate, and the anti-locking spring provides elastic restoring force; the No. 6 gear and the No. 7 gear mesh with each other and are connected to the motor drive assembly for transmission, driving the anti-locking sliding plate to achieve anti-locking extension and retraction.

[0009] As an improvement, a force-resisting plate is provided between the handle square shaft lever and the anti-locking sliding plate in the anti-locking assembly. The force-resisting plate is a bent elastic steel sheet structure with a buckling boss at one end and an arc-shaped abutment end at the other end. The force-resisting plate is assembled at the transmission engagement position between the handle square shaft lever and the anti-locking sliding plate.

[0010] As an improvement, the pin assembly also includes a pin rivet. The pin is hinged to the lock box by a pin rivet. One end of the pin return spring abuts against the pin and the other end abuts against the lock box. When the door is opened, it drives the pin to reset and release the limit on the latch.

[0011] As an improvement, the anti-insertion tongue assembly includes an anti-insertion tongue, an anti-insertion tongue bracket, and an anti-insertion tongue rivet; The anti-insertion tongue is hinged to the anti-insertion tongue bracket by anti-insertion tongue rivets. The anti-insertion tongue bracket is fixed to the lock box and works in conjunction with the oblique tongue to achieve anti-pry and anti-insertion.

[0012] As an improvement, the motor drive assembly includes a motor, a motor rotating wheel, a motor housing base, and a motor housing cover; The motor is installed between the motor housing base and the motor housing cover. The motor rotating wheel is connected to the motor output shaft and is connected to the square tongue assembly and the anti-lock assembly for transmission.

[0013] As an improvement, the circuit board is fixed inside the lock box and electrically connected to the motor and the latch switch plate, and is used to collect door status signals and control automatic locking, unlocking and deadbolting.

[0014] As an improvement, a magnet is fixedly installed on the tongue frame of the tongue assembly, and a magnet is fixedly installed on the pin plate of the pin assembly. The magnets one and two are respectively matched with the sensing elements on the circuit board.

[0015] The advantages of this invention compared to the prior art are: Truly versatile for both left and right, eliminating the need for direction adjustment: the latch can swing freely left and right, and the pin automatically limits the position after the door is closed. One lock body directly adapts to four opening methods: left opening, right opening, inward opening, and outward opening, greatly simplifying the production, warehousing, installation, and after-sales processes.

[0016] Anti-locking when the door is not closed, protecting the lock body structure: When the door is not closed, the deadbolt linkage plate automatically blocks the deadbolt sliding plate from extending, avoiding damage to the deadbolt from collision with the door frame caused by strong winds when closing the door, significantly improving the reliability of the lock body.

[0017] Automatic over-lift protection extends service life: A force-control plate is set between the handle square shaft lever and the anti-lock sliding plate. When the torque exceeds the limit, it will automatically disengage and reset by pressing down, preventing damage to the internal gears and transmission components from excessive upward lifting.

[0018] Stable structure, accurate sensing, and high degree of automation: Equipped with dual magnet position sensors, the circuit board detects the bolt status in real time, the motor drive is smooth, the anti-bolting linkage is reliable, and the overall safety and durability are significantly improved.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Example 1 As attached Figure 1 and attached Figure 2 As shown, an electronic lock body with directional adaptive and overload protection includes a lock box 1, a lock box cover 2, side strips 3, and decorative strips 4. The lock box cover 2 covers the lock box 1 and is fixed by lock box cover screws and threaded sleeves. The threaded sleeves are embedded in the mounting holes of the lock box 1 and lock box cover 2 for bolt fastening assembly of the lock body and the door body. The side strips 3 and decorative strips 4 are fixed to the side of the lock box 1. The lock body also includes a square latch assembly 5, a bevel latch assembly 6, a deadbolt assembly 7, a pin assembly 8, an anti-insertion latch assembly 9, a motor drive assembly 10, and a circuit board 11.

[0024] As attached Figure 2As shown, the square tongue assembly 5 includes a square tongue 51, a square tongue bracket 52, a square tongue moving pin 53, a square tongue rivet 54, and a square tongue return spring 55. The square tongue 51 is hinged to the square tongue bracket 52 via the square tongue rivet 54, fixing the square tongue bracket 52 inside the lock box 1. The square tongue moving pin 53 passes through the square tongue 51 and is connected to the motor drive assembly 10 for transmitting the motor drive force to the square tongue 51 to achieve the extension and retraction action. One end of the square tongue return spring 55 abuts against the square tongue 51, and the other end abuts against the lock box 1, providing a return elastic force for the square tongue 51, realizing the extension and retraction and automatic return of the square tongue 51.

[0025] As attached Figure 2 As shown, the latch assembly 6 includes a latch 61 that can swing freely left and right, a latch frame 62, a latch switch plate 63, a latch spring 64, a latch stop plate 65, a latch rod 66, a handle square shaft lever 67, a handle square shaft lever ring 68, and a square shaft lever spring 69. The latch 61 is installed inside the latch frame 62, and the latch 61 can swing adaptively left and right within the latch frame 62 to adapt to different door opening directions. The latch spring 64 abuts against the latch 61 to achieve elastic extension and contraction, providing extension preload for the latch 61. The latch rod 66 connects the latch 61 and the latch switch plate 63, and is used to transmit the extension and contraction movement of the latch 61 to the latch switch plate 63 to trigger door status detection. The handle square shaft lever 67 is sleeved on the handle square shaft lever ring 68 and elastically connected to the square shaft lever spring 69. The square shaft lever spring 69 is used for automatic reset after the handle square shaft lever 67 is rotated. When rotated, it drives the slanted tongue rod 66 to drive the slanted tongue 61 to extend and retract. The slanted tongue baffle 65 is fixedly installed in the lock box 1 and connected to the slanted tongue frame 62. It is used to limit the extension and retraction stroke and swing position of the slanted tongue 61 and prevent the slanted tongue 61 from deviating and getting stuck.

[0026] The pin assembly 8 includes a pin piece 81, a pin return piece 82, a pin piece return spring 84, and a pin linkage piece 85. When the latch 61 retracts, the pin linkage piece 85 pushes the pin return piece 82 to extend the pin piece 81 and limit the latch 61. After the pin piece 81 extends, it locks the swing position of the latch 61, completing the adaptive positioning of the direction. This enables the lock body to be universally adaptive in the left and right opening directions without the need for direction adjustment. The pin assembly 8 also includes a pin rivet 83. The pin 81 is hinged to the lock box 1 via the pin rivet 83, allowing the pin 81 to rotate around the pin rivet 83 to achieve limiting and unlocking actions. One end of the pin 84 abuts against the pin 81, and the other end abuts against the lock box 1, providing rotational return force for the pin 81. When the door is opened, it drives the pin 81 to reset, thereby releasing the limitation on the latch 61.

[0027] The deadbolt assembly 7 includes a deadbolt sliding plate 71, a deadbolt linkage plate one 73, and a deadbolt linkage plate two 74. The deadbolt linkage plate one 73 and the deadbolt linkage plate two 74 are triggered to swing by the extension and retraction position of the latch 61. When the latch 61 retracts, it causes the deadbolt linkage plate one 73 and the deadbolt linkage plate two 74 to swing. When the latch 61 extends, it keeps the deadbolt linkage plate one 73 and the deadbolt linkage plate two 74 in a blocking state. When the door is not closed, the deadbolt linkage plate one 73 and the deadbolt linkage plate two 74 block the deadbolt sliding plate 71 from extending, preventing the lock body from being damaged by collision due to deadbolt when the door is not closed. After the door is closed, the restriction is released to allow the deadbolt action.

[0028] The anti-locking assembly 7 further includes an anti-locking inclined plate 72, an anti-locking spring plate 77, a No. 6 gear 76, and a No. 7 gear 75. The anti-locking inclined plate 72 abuts against the anti-locking sliding plate 71 to push the anti-locking sliding plate 71 to extend smoothly. The anti-locking spring plate 77 provides an elastic restoring force, causing the anti-locking sliding plate 71 to automatically retract after unlocking. The No. 6 gear 76 and the No. 7 gear 75 mesh with each other and are connected to the motor drive assembly 10 for transmission, transmitting the motor torque to the anti-locking sliding plate 71 to drive the anti-locking sliding plate 71 to achieve anti-locking extension and retraction.

[0029] A force-resisting plate is provided between the handle square shaft lever 67 and the anti-lock sliding plate 71 in the anti-lock assembly 7. The force-resisting plate is a bent elastic steel plate structure with a buckling boss at one end and an arc-shaped abutment end at the other end. The force-resisting plate is assembled at the transmission engagement position between the handle square shaft lever 67 and the anti-lock sliding plate 71. It is not separately shown in the exploded view of the lock body.

[0030] Under normal conditions, the force plate relies on its own elasticity to engage with the handle square shaft lever 67 and the anti-lock sliding plate 71 through the buckle boss to transmit power. When the torque of lifting the handle exceeds the set value, the force plate is pushed open by external force to disengage and cut off the overload torque transmission, protecting the internal gears and transmission structure. After pressing down the handle, it automatically resets and locks under the action of the anti-lock spring plate 77 and the force plate's own elasticity to achieve overload protection.

[0031] The anti-insertion tongue assembly 9 includes an anti-insertion tongue 91, an anti-insertion tongue bracket 92, and an anti-insertion tongue rivet 93. The anti-insertion tongue 91 is hinged to the anti-insertion tongue bracket 92 by the anti-insertion tongue rivet 93, so that the anti-insertion tongue 91 can swing flexibly and move in conjunction with the oblique tongue 61. The anti-insertion tongue bracket 92 is fixed to the lock box 1 and moves in conjunction with the oblique tongue 61 to achieve anti-pry and anti-insertion, preventing foreign thin pieces from being inserted into the door gap to pry open the lock body.

[0032] Example 2 Based on Example 1, as shown in the appendix Figure 2As shown, the motor drive assembly 10 includes a motor 101, a motor rotating wheel 102, a motor housing base 103, and a motor housing cover 104. The motor 101 is installed between the motor housing base 103 and the motor housing cover 104. The motor housing base 103 and the motor housing cover 104 cooperate to form a closed receiving space to protect the motor 101. The motor rotating wheel 102 is connected to the output shaft of the motor 101 and is connected to the square latch assembly 5 and the deadbolt assembly 7 for transmission, converting the rotational motion of the motor 101 into the linear extension and retraction motion of the square latch 51 and the deadbolt sliding piece 71. The circuit board 11 is fixed inside the lock box 1 and electrically connected to the motor 101 and the inclined latch switch piece 63. It is used to receive door status sensing signals, determine the lock body position, and output control commands. It is used to collect door status signals and control automatic locking, unlocking, and deadbolting.

[0033] A magnet 610 is fixedly installed on the tongue frame 62 of the tongue assembly 6, and a magnet 86 is fixedly installed on the pin piece 81 of the pin assembly 8. The magnet 610 and the magnet 86 are respectively matched with the sensing element on the circuit board 11 to feed back the real-time position signal of the tongue 61 and the limit status signal of the pin piece 81 to the circuit board 11, so as to realize the non-contact accurate detection of the position of the tongue 61 and the pin piece 81.

[0034] The specific usage method is as follows: 1. Direction adaptive use When installing the lock body, there is no need to distinguish the door direction; it can be directly installed into the door body. The latch 61 can swing freely left and right within the latch frame 62. After the door is closed, the latch 61 is compressed back, and the pin return piece 82 is pushed by the pin linkage piece 85, so that the pin piece 81 extends and limits the latch 61, automatically matching the current door opening direction without manual adjustment.

[0035] 2. Normal door closing and automatic locking When the door is closed, the latch 61 is compressed back by the door frame, triggering the latch switch 63 to operate; the circuit board 11 senses the closed state through magnet 610 and magnet 86 and controls the motor 101 to start; the motor rotates the wheel 102 to drive the square latch to move the pin 53, so that the square latch 51 extends to complete the automatic locking; after the door is released, the square latch 51 remains in the extended state under the action of the square latch return spring 55.

[0036] 3. Deadbolt operation and anti-delock mechanism when the door is not closed After the door is fully closed, the latch 61 is in position, which drives the first locking linkage plate 73 and the second locking linkage plate 74 to swing, releasing the restriction on the locking sliding plate 71; at this time, lift the handle, and the handle square shaft dial 67 drives the locking sliding plate 71 to extend, realizing the locking. When the door is not closed, the first locking linkage plate 73 and the second locking linkage plate 74 always block the locking sliding plate 71, preventing the locking from extending and avoiding damage to the lock body from strong winds closing the door.

[0037] 4. Overload protection When the handle is lifted to lock, if the torque exceeds the set value, the force-controlling plate between the handle square shaft block 67 and the lock sliding plate 71 will automatically disengage, cutting off the transmission of overload torque; after the handle is pressed down, the force-controlling plate will automatically reset, the lock body will return to normal operation, and the gears and internal structure will not be damaged.

[0038] 5. Press down to open the door Pressing down the handle causes the handle square shaft lever 67 to rotate, which in turn drives the latch rod 66, causing the latch 61 to retract against the elastic force of the latch spring 64, thus opening the door. After releasing the handle, the latch 61 automatically extends and resets under the action of the latch spring 64.

[0039] 6. Anti-insertion tongue and anti-pry protection The anti-insertion latch 91 and the oblique latch 61 are linked. When the oblique latch 61 extends, the anti-insertion latch 91 extends simultaneously to prevent cards or thin pieces from being inserted into the door gap to pry open the lock, thereby improving anti-theft security.
