[0062] Example

[0063] This embodiment provides a lock tongue mechanism, which aims to solve the technical defects that the lock tongue and the door body are prone to mutual friction and compression, resulting in sufficient force required to open the door leaf, poor flexibility, and inability to meet the use requirements of intelligent door control.

[0064] like Figures 1 to 16 As shown, a bolt mechanism includes a bolt assembly 2, an operating assembly 3 and an unlocking assembly 4, wherein the bolt assembly 2 is adapted to be movably connected and arranged on a lock box 1; the bolt assembly 2 includes a bolt portion and a latch portion, wherein the bolt portion and the latch portion are rotatably arranged, and the bolt portion has a docking portion 212, wherein the docking portion 212 is arranged on an area where the bolt portion is adjacent to the latch portion; the operating assembly 3 includes a connecting member 31, wherein the connecting member 31 is adapted to be slidably arranged with the lock box 1; the unlocking assembly 4 includes a locking slider 44, wherein the locking slider 44 is slidably arranged with the latch portion, and the locking slider 44 has a limiting portion 442, wherein the limiting portion 44 42 and the docking portion 212 can be configured to fit together; wherein, under the action of external force, the connecting member 31 has the function of driving the unlocking assembly 4 to move along a first direction, compressing the locking elastic member (not shown in the figure), and causing the locking slider 44 to slide away from the locking tongue portion, so that the limiting portion 442 and the docking portion 212 are unlocked, and the locking tongue assembly 2 includes a locking elastic member, one end of which is suitable for being fixed to the lock box 1, and the other end of the locking elastic member is connected to the locking slider 44, and the locking slider 44 slides toward the locking tongue portion by elastic action, so that the limiting portion 442 and the docking portion 212 can be reset and locked.

[0065] The lock tongue mechanism provided in this embodiment has a locking stage in which the lock tongue assembly 2 is connected to the external door body, and the limiting portion 442 and the docking portion 212 are locked with each other, and the lock tongue part and the bolt part are relatively fixedly arranged; during the working process of the opening stage, the lock tongue part and the external door body will rub and squeeze each other, and the lock tongue part can be rotated relative to the bolt part through the linkage of the operating assembly 3 and the unlocking assembly 4, so that the unlocking displacement of the lock tongue part is more labor-saving and more flexible; specifically, through the sliding movement of the connecting member 31, the unlocking assembly 4 is linked to enable the lock tongue part to be unlocked. The closing slider 44 slides away from the lock tongue part, so that the limiting part 442 of the locking slider 44 and the docking part 212 of the lock tongue part are unlocked, so that the lock tongue part can be flexibly rotated relative to the bolt part, and the purpose of auxiliary unlocking and flexible unlocking is achieved by adding the operating component 3 and the unlocking component 4; if it is necessary to restore the lock tongue component 2 and the external door body to the locked state, the sliding force of the connecting member 31 can be removed, and the locking slider 44 can slide toward the lock tongue part by the elastic action of the locking elastic member, so that the limiting part 442 and the docking part 212 can be reset and locked. This solution can effectively assist in unlocking the connection between the lock tongue part and the external door body, and its operation process is more labor-saving and convenient for users and smart door control.

[0066] In a specific embodiment, the sliding movement of the connecting member 31 can be driven by an external actuating mechanism, such as an electric drive or a pneumatic drive, to automatically drive the linkage member, thereby driving the unlocking assembly 4 to move, so that the locking slider 44 is away from the locking tongue portion. For example, a rack is fixedly provided on the connecting member 31, and a gear meshing with the rack is provided in the lock box 1. The gear is driven by a micromotor so that the rack drives the sliding of the linkage member. Among them, in order to remove the sliding force of the connecting member 31, the sliding force of the connecting member 31 can be slowly removed so that the locking elastic member elastically acts on the locking slider 44 and other structures to reset; or the connecting member 31 can be slowly acted on to slide along the second direction so that the connecting member 31 and the unlocking assembly 4 are slowly reset. The first direction and the second direction are oppositely set, and the first direction can be specifically set to Figure 3 The height direction is in the downward direction.

[0067] For the structural design embodiment of the operating component 3 and the unlocking component 4:

[0068] For example, in some embodiments, Figures 4 to 6As shown, the unlocking assembly 4 also includes an unlocking paddle 41, an unlocking lever 42 and an unlocking lever 43. The unlocking paddle 41 and the connecting member 31 are slidably connected, the unlocking paddle 41 and the unlocking lever 42 are movably connected, the unlocking lever 43 is suitable for being rotatably configured in the lock box 1, one end of the unlocking lever 43 is slidably connected to the unlocking lever 43, the other end of the unlocking lever 43 is slidably connected to the latch part, the unlocking lever 43 and the locking slider 44 are transmission-connected, and the connecting member 31 is used for slidingly transmitting the unlocking paddle 41, so that the unlocking paddle 41 drives the unlocking lever 42, so as to act on the unlocking lever 43 to drive the locking slider 44 to slide away from the lock tongue part.

[0069] Through the sliding movement of the connecting piece 31, the connection position of the unlocking paddle 41 and the unlocking lever 42 is relatively adjusted, so that the unlocking lever 42 rotates in the lock box 1; during the rotation stroke of the unlocking lever 42, it can slide and abut the unlocking lever 43, so that the unlocking lever 43 then transmits the locking slider 44 to slide away from the lock tongue part, thereby achieving the purpose of assisting the rotation of the unlocking lock tongue part and the bolt part; when the door body is opened, the flexible rotation of the lock tongue part can reduce the friction and extrusion force between the lock tongue part and the door body; after the sliding force of the connecting piece 31 is removed, the locking slider 44 is reset by the locking elastic part, and accordingly, the linkage unlocking assembly 4 is reset as a whole; with this structural scheme, the transmission movement of auxiliary unlocking is stable and reliable, which can ensure the relative fixation of the lock tongue part and the bolt part when the door body is locked, and the effective working position of the relative rotation of the lock tongue part and the bolt part when the door body is opened.

[0070] For example, in some embodiments, Figure 6 and Fig.14 As shown, a connecting groove 311 is provided on the connecting piece 31, and the unlocking assembly 4 also includes a first movable member 45, a second movable member 46, a movable member 47 and a rotating member 48. The first movable member 45 and the second movable member 46 are arranged at intervals, the first movable member 45 is connected to the end of the unlocking paddle 41 away from the unlocking lever 42, the second movable member 46 is connected to the middle section of the unlocking paddle 41, and the first movable member 45 and the second movable member 46 are respectively slidably arranged in the connecting groove 311; the movable member 47 is movably arranged at the junction of the unlocking paddle 41 and the unlocking lever 42, the rotating member 48 is suitable for connecting with the lock box 1, and the rotating member 48 and the unlocking lever 43 are rotationally connected. During the sliding movement of the connecting member 31, the connecting groove 311 limits and guides the moving positions of the first movable member 45 and the second movable member 46 therein, so as to drive the unlocking paddle 41 to move horizontally; the unlocking paddle 41 and the unlocking lever 42 are connected by the movable member 47, so that the translation of the unlocking paddle 41 drives the unlocking lever 42 to rotate around the rotating member 48, so as to cause the unlocking lever 43 to rotate, thereby causing the unlocking lever 43 to transmit force to cause the locking slider 44 to slide away from the lock tongue part.

[0071] For example, in some embodiments, Fig.13 , Fig.15 and Fig.16 As shown, the unlocking lever 43 is provided with a rotating portion 431 and a force transmission portion 432, the rotating portion 431 and the force transmission portion 432 are arranged at intervals, the rotating portion 431 is suitable for being rotatably connected with the lock box 1, the locking slider 44 is provided with a connecting portion 441, the force transmission portion 432 and the connecting portion 441 are rotatably connected, and the rotation axis of the rotating portion 431 is parallel to the rotation axis of the rotating member 48 and is arranged at intervals. The rotating portion 431 establishes the rotation axis between the unlocking lever 43 and the lock box 1, and the force transmission portion 432 establishes the rotation axis between the unlocking lever 43 and the locking slider 44.

[0072] For example, in some embodiments, Fig.14 As shown, the connection groove 311 includes a first groove section 3111 and a second groove section 3112 that are connected. The first groove section 3111 is extended along the sliding direction of the connection member 31, and the extension direction of the first groove section 3111 intersects with the extension direction of the second groove section 3112. In the locked state of the door body, the first moving member 45 abuts against the end of the second groove section 3112 away from the first groove section 3111, and the second moving member 46 abuts inside the second groove section 3112; when the connection member 31 slides along the first direction, the first moving member 45 gradually slides and moves from the second groove section 3112 to the second groove section 3112, and the second moving member 46 gradually slides and moves toward the end of the first groove section 3111 away from the second groove section 3112, so that the unlocking paddle 41 moves in a horizontal direction in the space.

[0073] For example, in some embodiments, the first movable member 45 and the second movable member 46 can be fixedly connected or rotatably connected to the unlocking paddle 41. Preferably, they are configured to be rotatably connected. For example, the first movable member 45 and the second movable member 46 can be configured as a combination structure of a guide column and a bearing, and the bearing is sleeved on the guide column, and the bearing is slidably abutted against the connecting groove 311. This arrangement is conducive to enhancing the smoother translational movement of the unlocking paddle 41.

[0074] For example, in some embodiments, Fig.15 As shown, the unlocking paddle 41 is configured with an adjustment slot 411, and the movable member 47 is slidably arranged in the adjustment slot 411. The unlocking paddle 41 and the unlocking lever 42 are slidably and rotatably arranged through the adjustment slot 411 and the movable member 47. Through the connection between the adjustment slot 411 and the movable member 47, the translational motion of the unlocking paddle 41 can flexibly drive the unlocking lever 42 to rotate, thereby avoiding the structure from being stuck.

[0075] For example, in some embodiments, the movable component 47 is configured as a combination structure of a guide column and a bearing, the bearing is sleeved on the guide column, and the bearing is slidably abutted against the adjustment groove 411, which is conducive to promoting smooth movement of the unlocking paddle 41 and the unlocking lever 42.

[0076] For example, in some embodiments, Figure 5 , Fig.13 and Fig.15 As shown, the unlocking lever 43 is further provided with a first rolling end 433 and a second rolling end 434, the first rolling end 433 and the latch portion are arranged in rolling contact, and the second rolling end 434 and the unlocking lever 42 are arranged in rolling contact; the unlocking lever 42 is configured with an extended edge 421 to contact the second rolling end 434. This arrangement sets the contact between the unlocking lever 43 and the latch portion, and the contact between the unlocking lever 43 and the unlocking lever 42 in a rolling form, which is conducive to smooth contact between the structures, stable force transmission, and is conducive to reducing structural wear and extending service life.

[0077] In a specific embodiment, the first rolling end 433 and the second rolling end 434 can be respectively configured as a combination structure of a connecting column and a bearing member / rolling wheel, the connecting column and the unlocking lever 43 are fixedly connected, and the bearing member / rolling wheel is sleeved on the connecting column.

[0078] For example, in some embodiments, Fig.14 As shown, the connecting member 31 is provided with an upper abutting portion 312 and an assembly portion 314, the upper abutting portion 312 is suitable for abutting against the inner wall of the lock box 1, and the upper abutting portion 312 is bent away from the sliding direction of the connecting member 31, which is beneficial for the linkage member to form a reliable contact with the inner wall of the lock box 1 when the linkage member slides and resets, thereby improving the stability of the connecting member 31 at the end of the reset sliding stroke; the assembly portion 314 is suitable for being arranged outside the lock box 1, and the assembly portion 314 can specifically be used to connect an external actuator mechanism that drives the linkage member to slide, and the actuator mechanism is suitable for driving the linkage member to slide along the first direction and the second direction.

[0079] For example, in some embodiments, Figure 3 and Fig.14 As shown, the connecting member 31 is configured with a first guide groove 315 and a second guide groove 316 arranged at intervals, and any guide groove is extended along the sliding direction of the connecting member 31. The operating assembly 3 also includes a first positioning pin 32 and a second positioning pin 33, and any positioning pin is suitable for being fixedly connected with the lock box 1. The first guide groove 315 is slidably arranged with the first positioning pin 32, and the second guide groove 316 is slidably arranged with the second positioning pin 33. The guide stroke of the first guide groove 315 is the same as the guide stroke of the second guide groove 316. This arrangement is conducive to enhancing the motion accuracy of the sliding motion of the connecting member 31, so as to improve the accuracy of the motion of the linkage unlocking assembly 4, and ensure the working position of the locking slider 44 and the lock tongue part relative to each other for locking and unlocking.

[0080] In this embodiment, if Figure 3 and Figure 7 As shown, the locking tongue portion includes a first locking tongue 21, a docking portion 212 is arranged on the side of the first locking tongue 21 facing the locking slider 44, and a limiting portion 442 is arranged on the side of the locking slider 44 facing the first locking tongue 21. In a specific structural embodiment, the docking portion 212 can be set to be two or more combined curved surfaces, two or more combined planes, or a combination of a curved surface and a plane, wherein the limiting portion 442 is conformally fitted with the docking portion 212. In terms of design, the conformal wall forms of the limiting portion 442 and the docking portion 212 that can ensure that the locking slider 44 and the first locking tongue 21 are abutted and fixed are within the protection scope of this embodiment.

[0081] For the structural design embodiment of the lock tongue assembly 2:

[0082] For example, in some embodiments, Figure 6 , Fig.12 and Fig.13 As shown, the latch part includes a fixed mounting seat 23 and a pin rod 24, the first locking tongue 21 and the mounting seat 23 are rotatably connected, the locking elastic member is sleeved on the pin rod 24, and the locking slider 44 is sleeved and slid on the pin rod 24. The mounting seat 23 is used to rotatably mount the first locking tongue 21, and the pin rod 24 serves as a mounting base for the locking slider 44 and the locking elastic member.

[0083] For example, in some embodiments, Figure 3 , Figure 7 as well as Fig.11 As shown, the bolt assembly 2 further includes a second bolt 22 and a fixing pin 25. The first bolt 21 and the second bolt 22 are connected and arranged on the mounting seat 23 through the fixing pin 25. The mounting seat 23 is provided with a pivot hole 231 to assemble the fixing pin 25. The second bolt 22 is provided with a rotating portion 222, which can at least be arranged in contact with the mounting seat 23. The mounting seat 23 and the locking slider 44 can jointly contact the rotating portion 222 supporting the second bolt 22. When the bolt part is in the locked working position, and the linkage member and the unlocking assembly 4 are linked to unlock the locking slider 44 to lock the bolt part, the rotating portion 222 can be in contact with the mounting seat 23. On the one hand, the force transmission of the bolt part in the locked state is stable and the structural strength is ensured. On the other hand, in the auxiliary unlocking stage, the rotating portion 222 is in rotational contact with the mounting seat 23 to rotate stably and flexibly; the rotating portion 222 can be configured as a cylindrical surface with a common rotation axis with the second bolt 22.

[0084] For example, in some embodiments, Figure 7As shown, the first locking tongue 21 includes a first body 211 and a docking portion 212. The first body 211 is configured as an inclined tongue structure, and the docking portion 212 is configured at the end surface area of ​​the inclined tongue structure adjacent to the locking slider 44. The docking portion 212 is configured as a locking docking surface to dock and match with the limiting portion 442 of the locking slider 44.

[0085] For example, in some embodiments, Figure 7 As shown, the second locking tongue 22 includes a second body 221 and a rotating portion 222. The second body 221 is configured as an inclined tongue structure, and the rotating portion 222 is configured at the end surface area of ​​the inclined tongue structure adjacent to the locking slider 44. The rotating portion 222 is configured as a curved surface structure.

[0086] For example, in some embodiments, the first lock tongue 21 and the second lock tongue 22 are rotatably set on the mounting seat 23 through the fixing pin 25. Specifically, the first lock tongue 21 and the fixing pin 25 are rotatably set, the second lock tongue 22 and the fixing pin 25 are rotatably set, and the fixing pin 25 and the mounting seat 23 are rotatably set; or, the first lock tongue 21 and the fixing pin 25 are rotatably set, the second lock tongue 22 and the fixing pin 25 are fixedly connected, and the fixing pin 25 and the mounting seat 23 are rotatably set; or, the second lock tongue 22 and the fixing pin 25 are rotatably set, the first lock tongue 21 and the fixing pin 25 are fixedly connected, and the fixing pin 25 and the mounting seat 23 are rotatably set.

[0087] For example, in some embodiments, Figure 6 and Fig.11 As shown, the mounting seat 23 is provided with a contact edge 232 for slidingly abutting against the unlocking lever 43 . Preferably, the contact edge 232 is in rolling abutment with the first rolling end 433 of the unlocking lever 43 .

[0088] For example, in some embodiments, Fig.11 As shown, the mounting seat 23 is provided with one or more protrusions 233, and the protrusions 233 are suitable for slidingly engaging with the lock box 1. For example, two protrusions 233 are provided, and two protrusions 233 are relatively arranged on both sides of the mounting seat 23, and the lock box 1 is provided with a first restraining groove 112 and a second restraining groove 121, so as to correspond to the two protrusions 233 for sliding and limiting engagement.

[0089] For example, in some embodiments, Figure 5 As shown, the latch part also includes a positioning plate 26, which is suitable for being fixed in the lock box 1. One end of the locking elastic member elastically abuts against the end surface of the positioning plate 26 facing the lock tongue part, and the other end of the locking elastic member elastically abuts against the end surface of the locking slider 44 away from the lock tongue part. The positioning plate 26 serves as the installation base of the locking elastic member and can reset the lock tongue mechanism as a whole, so that the operating component 3 and the unlocking component 4 can repeatedly switch between the locking action and the unlocking action of the lock tongue part.

[0090] For example, in some embodiments, Fig.16 As shown, the locking slider 44 is provided with a supporting portion 443, a recessed portion 444 and a through portion 445. When the limiting portion 442 and the docking portion 212 are locked, the supporting portion 443 is arranged in contact with the rotating portion 222 of the second locking tongue 22; the recessed portion 444 is used for assembling the mounting seat 23 to enhance the compactness of the structure, and the through portion 445 and the pin rod 24 are slidably connected.

[0091] For example, in some embodiments, Figure 5 and Fig.11 As shown, the latch part also includes a limit card 27, and a card slot 241 is recessed on the pin rod 24. The limit card 27 is clamped in the card slot 241, and the card slot 241 is arranged on the path of the locking slider 44 away from the lock tongue part. The limit card 27 is used to limit the sliding stroke of the locking slider 44 on the pin rod 24.

[0092] For example, in some embodiments, Figure 3 , Figure 5 as well as Fig.14 As shown, the latch part also includes a positioning shaft 28, and a connecting hole 242 is provided on the pin rod 24 of the latch part to connect the positioning shaft 28; a firing part 313 is provided on the connecting piece 31, and the lock tongue mechanism also includes an opening component, and the opening component includes a trigger plate 51 and a limiting member 52, the trigger plate 51 and the positioning shaft 28 are movably arranged, the trigger plate 51 and the limiting member 52 are rotatably arranged, and the limiting member 52 is suitable for being rotatably connected with the lock box 1, the trigger plate 51 is arranged on the sliding path of the firing part 313 toward the opening component along the connecting piece 31, and the firing part 313 is suitable for contacting the trigger plate 51 to link the displacement of the positioning shaft 28 and drive the lock tongue part and the latch part to move. According to this solution, the connecting member 31 slides close to the opening assembly, and the trigger plate 51 is contacted by the firing portion 313. One end of the trigger plate 51 is rotatably connected to the limiting member 52, and the other end of the trigger plate 51 is movably arranged with the positioning shaft 28, so that the trigger plate 51 rotates around the limiting member 52, and the trigger plate 51 is linked to the positioning shaft 28 and the pin rod 24 of the latch part. Figure 3 and Figure 4 The vertical displacement moves downward, so that the latch part and the lock tongue part are displaced together to realize the opening operation of the door body; wherein, the sliding displacement of the firing part 313 on the connecting member 31 to the trigger plate 51 is greater than the unlocking displacement of the locking slider 44 sliding away from the lock tongue part, so that the displacement of the connecting member 31 is divided into two displacement stages, first, in the first displacement stage, the locking slider 44 is unlocked from the lock tongue part, and then in the second displacement stage, the opening component is triggered to cause the latch part and the lock tongue part to displace into the lock box 1 to realize the opening of the door body. This arrangement is conducive to the smooth operation of the structure and the door body can be opened more labor-saving.
