Description

Technical Field

[0001] The utility model relates to the field of locks, in particular to an anti-stuck electronic lock body. Background Art

[0002] At present, door locks are a kind of lock commonly used in home furnishing. With the extensive application of electronic products in life, the traditional lock manufacturing industry has also begun to enter the new field of information and intelligence, such as mobile phone remote control unlocking, face and fingerprint recognition unlocking, etc., which are constantly pouring into the home life of ordinary consumers. Some existing electromechanical automatic locks are equipped with a motor that can drive the main lock tongue to lock and unlock, and a sensor that cooperates with the triggering latch tongue. When the door is closed, the triggering latch tongue is squeezed into the lock body by the door frame, triggering the sensor and feeding back a signal to the motor, and then the motor drives the main lock tongue to pop out, thereby realizing the function of closing the door and locking itself.

[0003] Although existing automatic locks can achieve automatic unlocking and locking through motors, when the motor fails or the transmission component is stuck, most of the current electric door locks cannot be used, and the door cannot be opened manually, causing the user to be unable to open the door. Therefore, the stability and reliability are poor and cannot effectively meet the needs of current users.

[0004] If the patent publication number is CN113090121A , in the Chinese invention patent application for an anti-stuck electronic lock body, the disclosed technical solution is: through the sliding push rod A and the movable and swinging push rod B, the transmission is transmitted between the gear shift assembly and the oblique tongue shift fork. When the motor suddenly breaks down and gets stuck, if the gear shift assembly is in a position to block the retraction of the push rod B, when the key or door handle opens the door, after the lock tongue retracts a certain distance, the push rod B contacts the gear shift assembly, and the push rod B can swing for the lock tongue to continue to retract, avoiding the situation where the lock cannot be opened. At the same time, according to the content disclosed in its specification: when the motor suddenly breaks down and causes the gear dial to get stuck, there will be two situations. The first situation is that the meshing teeth just mesh with the rack, which causes the lock tongue to get stuck, and the key and door handle cannot open the lock normally; the other situation is that the meshing teeth are outside the rack, and the lock tongue is not affected at this time, and the key and door handle can open the lock normally, thereby reducing the situation where the lock tongue gets stuck and cannot open and close the door normally.

[0005] In the technical solution disclosed in the above patent, due to its complex structure, there are two cases where the gear dial is stuck when the motor is damaged. When the first case occurs, it is necessary to further disconnect the meshing state of the gear transmission mechanism through the clutch device before the key can be used to unlock the door, which makes it extremely inconvenient for the user to use the key to unlock the door. Although it solves the technical problem that when the motor fails, the user can still open the door with the key, but the lock body structure is extremely complex and has many parts, which is not conducive to production and assembly, and is not conducive to saving the lock body space, and increases the lock body space occupation and material waste.

[0028] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0029] like Figures 1 to 6As shown, the present invention provides an anti-stuck electronic lock body, which specifically includes a lock shell 100, and a mounting cavity is provided in the lock shell 100 to facilitate the installation of various components. The main lock tongue assembly 1 is movably connected in the lock shell 100, and the main lock tongue assembly 1 is locked / unlocked through the movably connected. A flip tongue assembly 2 is arranged above the main lock tongue assembly 1, and a safety tongue assembly 3 is arranged between the main lock tongue assembly 1 and the flip tongue assembly 2. The setting of the safety tongue assembly 3 is used to lock / unlock the flip tongue assembly 2. A motor assembly 4 for driving the main lock tongue assembly 1 to extend and retract relative to the inside and outside of the lock shell 100 is also installed in the lock shell 100, and the motor assembly 4 is arranged between the main lock tongue assembly 1 and the safety tongue assembly 3. A transmission assembly 5 is arranged between the motor assembly 4 and the main lock tongue assembly 1, and the transmission assembly 5 is used to drive the main lock tongue assembly 1 and the motor assembly 4 to connect. The transmission assembly 5 and the main lock tongue assembly 1 are connected by the first paddle assembly 6 to realize the internal and external telescopic movement of the main lock tongue assembly 1 relative to the lock housing 100, and the lower end of the transmission assembly 5 is also connected with the second paddle assembly 7. The second paddle assembly 7 can drive the transmission assembly 5 to move, thereby driving the first paddle assembly 6 to move, and at the same time drive the main lock tongue assembly 1, the bucket tongue assembly 2, and the safety lock tongue assembly 3 to move, so as to realize manual unlocking. The first paddle assembly 6 is connected with the safety tongue assembly 3 through the linkage mechanism 8 to realize locking / unlocking of the bucket tongue assembly 2.

[0030] It should be noted that the positions and connection relationships between the above-mentioned components are arranged in the manner provided in this case, which is conducive to the linkage between the components and to better installation and arrangement of the components in the lock shell 100, thereby achieving a reduction in the volume of the lock shell 100. Compared with the prior art, the electronic lock body can be made smaller, lighter and thinner.

[0031] As 1- Figure 3 As shown, the main lock tongue assembly 1 comprises a main lock tongue 11 which can be extended / retracted into the lock housing 100, and a main lock tongue mounting plate 12 which is fixedly connected to the main lock tongue 11 at one end. The main lock tongue mounting plate 12 is used to connect and fix the main lock tongue 11 so that the main lock tongue 11 can be stably extended / retracted into the side wall of the lock housing 100, thereby achieving locking / unlocking. The other end of the main lock tongue mounting plate 12 is connected to the transmission assembly 5 through the first paddle assembly 6. In specific implementation, a U-shaped notch is provided on the main lock tongue mounting plate 12, and the first paddle 61 of the first paddle assembly 6 is inserted into the U-shaped notch, thereby driving the lock tongue mounting plate to move.

[0032] As 1- Figure 3As shown, the bucket tongue assembly 2 includes a bucket tongue 21 extending out of the lock housing 100, a locking structure 22 connected to the bucket tongue 21, and a bucket tongue mounting plate 23 fixedly arranged on the side wall of the lock housing 100. The bucket tongue mounting plate 23 is used to connect and fix the bucket tongue 21 so that the bucket tongue 21 can be stably flipped, thereby achieving locking / unlocking. The locking structure 22 includes a movable plug-in 221 connected to the linkage mechanism 8 at one end. The locking mechanism 22 is used to lock / unlock the flipping of the bucket tongue 21. Specifically, the locking / unlocking of the bucket tongue 21 is achieved by pulling the plug-in 221 through the linkage mechanism 8.

[0033] like Figure 1-Figure 3 As shown, the safety tongue assembly 3 includes a safety tongue 31 that can be extended / retracted into the lock housing 100, a safety tongue push rod 32 with one end fixedly connected to the safety tongue 31, and the other end of the safety tongue push rod 32 is elastically connected to the linkage mechanism 8 through a compression spring 33. The setting of the safety tongue assembly 3 is used to cooperate with the linkage mechanism 8 to achieve locking / unlocking of the bucket tongue 21. In specific implementation, the compression spring 33 is sleeved on the safety tongue push rod 32. Under normal conditions, the safety tongue 31 is always in a state of extending out of the lock housing 100. At this time, the bucket tongue 21 can be turned over to facilitate users to open and close the door. That is, when the safety tongue 31 is pressed by force, the linkage mechanism 8 is pushed to operate through the safety tongue push rod 32, and the linkage mechanism 8 pulls the plug-in 221, thereby locking the bucket tongue 21. When the external force is released, under the elastic force of the compression spring 33, the safety tongue 31 is reset and extends out of the lock housing 100, thereby unlocking the bucket tongue 21.

[0034] like Figure 1-Figure 3 , Figure 5 As shown, the motor assembly 4 includes a motor 41 and a circuit board 42 electrically connected to the motor 41. The motor 41 includes a motor gear 411 meshed with the transmission assembly 5, so that the motor 41 drives various components to realize the electric unlocking / unlocking of the electronic lock body of this case.

[0035] like Figure 1-Figure 4 As shown, the linkage mechanism 8 includes a first connecting plate 81 provided at the bottom of the lock housing 100, and a linkage piece 82 connected to the first connecting plate 81, and the other end of the linkage piece 82 abuts against the safety tongue assembly 3. That is, the first connecting plate 81 realizes linkage with the safety tongue assembly 3 through the linkage piece 82, and the movement of the first connecting plate 81 can drive the movement of the safety tongue assembly 3. The first connecting plate 81 is respectively provided with a first through hole 811 and a second through hole 812, and the linkage piece 82 is rotatably connected to the first connecting plate 81 through a fixed shaft 83, thereby being linked with the safety tongue assembly 3. One end of the linkage piece 82 abuts against the first connecting plate 81, and the other end abuts against the safety tongue assembly 3. Through the movement of the first connecting plate 81, the linkage piece 82 is driven to rotate around the fixed shaft 83 as the axis.

[0036] The fixed shaft 83 passes through the first through hole 811 and is fixedly connected to the lock housing 100. The first through hole 811 and the second through hole 812 are provided to stably install the first connecting plate 81 on the lock housing and stably move when the first connecting plate 81 is in linkage. The second through hole 812 is also provided to install the fixed shaft 83 so as to rotatably connect the linkage piece 82 thereto. The first connecting plate 81 is elastically connected to the lock housing 100 through a tension spring 84. The tension spring 84 is provided to facilitate the limiting and resetting of the first connecting plate 81 when the first connecting plate 81 pulls the plug-in 221 to lock / unlock the bucket tongue 21, which is beneficial to the stability of the linkage mechanism 8 when the linkage is in linkage.

[0037] like Figure 1-Figure 3 , Figure 5 As shown, the transmission assembly 5 includes a first connecting shaft 51 fixedly arranged on the lock housing 100, a second connecting shaft 52 located below the first connecting shaft 51, a double gear 53 rotatably sleeved on the first connecting shaft 51, and a transmission gear 54 rotatably sleeved on the second connecting shaft 52 and meshing with the double gear 53, and the lower end of the double gear 53 meshes with the motor assembly 4. In specific implementation, the double gear 53 has two upper and lower gears, the lower gear meshes with the motor assembly 4, and the upper gear meshes with the transmission gear 54. The transmission assembly 5 of this case only realizes the transmission between the motor assembly 4 and the main lock tongue assembly 1 by setting two gears, the double gear 53 and the transmission gear 54. Its structure is simple and the unlocking is convenient and fast. It should be noted that the structure of the double gear 53 is a well-known technology in the art, so it is not specifically described. In specific implementation, the lock housing 100 is integrally formed with the lock housing 100 and is provided with many pins and connecting shafts to facilitate the installation, connection and limiting of various components. This belongs to the conventional design in the art, so it is not specifically described in this case.

[0038] Further, referring to FIG. Figure 1-Figure 3 , Figure 5As shown, the first paddle assembly 6 includes a first paddle 61, and a second paddle 62 coaxially arranged at the lower end of the first paddle 61 and capable of coaxially rotating with the first paddle 61. The first paddle 61 and the second paddle 62 are both sleeved on the second connecting shaft 52. The first paddle 61 is installed above the transmission gear 54 and abuts against the main lock tongue assembly 1 to drive the main lock tongue assembly 1 to extend and retract relative to the lock housing 100. The second paddle 62 is installed below the transmission gear 54. One end of the second paddle 62 abuts against the linkage mechanism 8, and the other end abuts against the second connecting plate 63. In specific implementation, the first paddle 61 and the second paddle 62 both rotate synchronously with the transmission gear 54. When the motor assembly 4 drives the transmission assembly 5 to move, the first paddle 61 and the second paddle 62 move simultaneously. The first paddle 61 drives the main lock tongue mounting plate 12 to drive the main lock tongue 11 to extend and retract relative to the lock housing 100, thereby realizing the locking / unlocking of the main lock tongue assembly 1. The second paddle 62 is used to drive the linkage mechanism 8 and the second connecting plate 63 to unlock the safety tongue assembly 3. It should be noted that in order to facilitate the abutment between the second paddle 62, the second connecting plate 63 and the linkage mechanism 8, the second paddle 62 is set to a V-shaped sheet structure, and the positions of the first paddle 61 and the second paddle 62 on the transmission gear 54 need to be set in advance to ensure that the travel of the first paddle 61 and the second paddle 62 do not interfere with each other. The above-mentioned structural design and installation position setting make the overall transmission efficiency of the electronic lock body of this case high, the unlocking is convenient, and the installation space is saved.

[0039] Continue to refer to Figure 1-Figure 3 , Figure 5 , Figure 6 As shown, the second paddle assembly 7 includes a mounting seat 71 fixedly mounted on the bottom of the lock housing 100, a third paddle 72 movably connected to the mounting seat 71, a slide groove 711 is provided on the mounting seat 71, one end of the third paddle 72 is slidably connected in the slide groove 711, and the other end of the third paddle 72 is provided with a gear 721, and the third paddle 72 is meshed with the transmission gear 54 through the gear 721. In specific implementation, in order to facilitate meshing with the transmission gear 54 and shorten the stroke of manual unlocking, one end of the third paddle 72 provided with the gear 721 is arc-shaped, and the gear 721 is provided with a plurality of gears.

[0040] As described above, further, a lock core installation slot 101 is provided on the lock housing 100, and a lock core 102 is provided in the lock core installation slot 101. The second connecting plate 63 includes a first connecting end 631 abutting against the second paddle 62 and a second connecting end 632 for abutting against the lock core 102. In specific implementation, the second connecting plate 63 is in a sheet shape as a whole, wherein the second connecting end 632 is bent upward so as to better abut against the lock core 102 to realize manual locking / unlocking of the safety tongue assembly 3. When the motor 41 is stuck and needs to be manually unlocked, the user rotates the lock core 102 with a key, and the paddle block of the lock core 102 runs along the path of the slide groove 711, thereby driving the third paddle 72 to slide in the slide groove 711, and the third paddle 72 drives the transmission gear 54 to move, thereby driving the motor gear 411 of the motor 41 to reverse, and at the same time, the various components are linked to realize unlocking. For details, please refer to the description of the working principle below.

[0041] The working principle of this case is:

[0042] 1. When the electronic lock body in this case is in the working state of automatic motor locking:

[0043] Due to the force applied by closing the door, the first connecting plate 81 is pushed and retracted through the safety tongue push rod 32, and the first connecting plate 81 is pulled outward to pull the plug-in 221 of the locking structure 22 on the flip tongue 21, thereby locking the flip tongue 21. The motor 41 is automatically controlled to start through a predetermined program of the circuit board 42, and the motor gear 411 of the motor 41 starts to rotate forward to drive the double gear 53 to rotate, and the double gear 53 drives the transmission gear 54 to rotate. When the transmission gear 54 rotates, the first paddle 61 rotates at the same time, and the first paddle 61 drives the main lock tongue mounting plate 12 to drive the main lock tongue 11 to extend outward relative to the lock shell 100, thereby realizing the locking of the electronic lock body in this case.

[0044] 2. When the electronic lock body in this case is in the working state of automatic unlocking by the motor:

[0045] The rest of the working principles are consistent with those in the above-mentioned locked state, the difference being that when unlocking, the motor gear 411 starts to rotate in the reverse direction until the second paddle 62 drives the first connecting plate 81 and the second connecting plate 63 at the same time, and the first connecting plate 81 moves upward, thereby pushing the plug-in 221 of the locking structure 22 on the flip tongue 21 to retract into the inside of the locking structure 22, thereby unlocking the flip tongue 21. At this time, the user holds the handle and pushes the door, the flip tongue 21 flips over, and the door can be pushed open.

[0046] 3. Working status when the electronic lock motor fails and needs to be manually unlocked:

[0047] The rest of the working principle is consistent with the working state of the above-mentioned motor automatic unlocking. The difference is that the user needs to use the key to rotate the lock cylinder 102, and the shift block of the lock cylinder 102 runs along the path of the slide groove 711, thereby shifting the third shift piece 72 to slide in the slide groove 711, and the transmission gear 54 is driven by the third shift piece 72 to move.

[0048] As mentioned above, this case protects an anti-stuck electronic lock body, and all technical solutions that are the same or similar to this case should be shown to fall within the protection scope of this case.
