[0068] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the specification of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the present application.

[0069] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0070] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0071] The first aspect of the embodiments of the present application provides a lock transmission assembly that can take into account both left-opening and right-opening door opening methods, so that only one type of mold needs to be made to correspond to door bodies that open in different directions, thereby improving the adaptability of the production mold and reducing production costs.

[0072] Specifically, if Figure 1 and Figure 2 As shown, taking the locking tongue 110 adopting a sliding locking method as an example, Figure 1 In the left-opening door lock body 100 shown, the lock tongue 110 needs to slide to the left when locking; Figure 2 In the right-opening lock body 100 shown, the lock tongue 110 needs to slide to the right when locking. Therefore, the lock transmission assembly that drives the lock tongue 110 to move in different directions in different door opening modes needs to drive the lock tongue 110 to move in different directions, and therefore the existing lock transmission assembly needs to be provided with two molds.

[0073] like Figures 1 to 5 As shown, the lock transmission assembly provided in this embodiment includes: a support member 10, a lock body connecting member 20, a first transmission member 30 and two second transmission members 40. The support member 10 is used to connect the lock body 100. The two second transmission members 40 are rotatably arranged on the support member 10; taking the lock body 100 placed horizontally and the lock tongue 110 sliding in the left and right directions as an example, the two second transmission members 40 can be arranged in sequence in the left and right directions.

[0074] The first transmission member 30 is reciprocatably or rotatably disposed on the support member 10 ; the first transmission member 30 meshes and connects the two second transmission members 40 , so that the first transmission member 30 can drive the second transmission member 40 to rotate when reciprocatingly or rotating.

[0075] The lock body connecting member 20 is detachable and synchronously rotated to connect one of the two second transmission members 40; the lock body connecting member 20 is used to transmit and connect the lock tongue 110 in the lock body 100, so that when the second transmission member 40 drives the lock body connecting member 20 to rotate, it can drive the lock tongue 110 to move to achieve locking or unlocking.

[0076] As an implementation manner, the support member 10 may be the lock body 100 itself, that is, the support member 10 and the lock body 100 are integrated, which can reduce the number of components.

[0077] As an implementation method, the support member 10 may also be a component separately arranged relative to the lock body 100. Figures 1 to 5 In the illustrated embodiment, the support member 10 can be detachably connected to the lock body 100 by using connecting members such as bolts, so as to facilitate the disassembly and assembly of the entire lock transmission assembly.

[0078] As an embodiment, the first transmission member 30 is reciprocatably disposed on the support member 10 along the horizontal direction of the mounting plane of the support member 10; for ease of description, in this solution, the end surface of the door body on which the support member 10 is mounted is taken as the vertical surface; specifically, Figure 5 As shown, the first transmission member 30 may be a rack, and the second transmission member 40 may be a gear. The first transmission member 30 directly meshes with the two second transmission members 40 or meshes and connects the two second transmission members 40 through an intermediate gear 31, so that when the first transmission member 30 reciprocates in the left and right directions along the horizontal direction of the support member 10, it can drive the two second transmission members 40 to rotate forward or reverse.

[0079] As an implementation mode, the first transmission member 30 and the second transmission member 40 may both be gears; specifically, as Figure 6 As shown, the first transmission member 30 is meshedly connected with the two second transmission members 40. The user drives the first transmission member 30 to rotate by twisting, etc., which can drive the second transmission member 40 and the lock body connecting member 20 to rotate.

[0080] For the convenience of description, in the following description, the first transmission member 30 is assumed to be a rack, and the first transmission member 30 is meshedly connected to the second transmission member 40 via the intermediate gear 31 .

[0081] In the left-hand opening mode, the lock body connector 20 can be installed on Figure 5 During the locking process, the first transmission member 30 slides to the left, driving the second transmission member 40 on the left to rotate counterclockwise, thereby causing the lock body connecting member 20 to rotate counterclockwise and push the lock tongue 110 to slide to the left to lock. Similarly, the first transmission member 30 slides to the right to drive the lock tongue 110 to slide to the right to unlock.

[0082] In the right-hand opening mode, the lock body connector 20 can be installed on Figure 5During the locking process, the first transmission member 30 slides to the right, driving the second transmission member 40 on the right to rotate clockwise, thereby causing the lock body connecting member 20 to rotate clockwise and push the lock tongue 110 to slide to the right to lock. Similarly, the first transmission member 30 slides to the left to drive the lock tongue 110 to slide to the left to unlock.

[0083] In actual applications, the door body needs to be limited when installed with the door frame; Figure 1 and Figure 2 As shown, in order to prevent the lock transmission assembly from interfering with the installation of the door body, the installation position of the lock transmission assembly needs to maintain a certain distance from the frame of the lock body 100. Therefore, in this embodiment, in the left-opening mode, the lock body connecting member 20 can be installed on the second transmission member 40 on the left side, so that the lock transmission structure maintains a sufficient distance from the left side frame of the lock body 100; in the right-opening mode, the lock body connecting member 20 can be installed on the second transmission member 40 on the right side, so that the lock transmission structure maintains a sufficient distance from the right side frame of the lock body 100.

[0084] Therefore, the lock transmission assembly provided in this embodiment can select the installation position of the lock body connector 20 according to the door opening method, so as to take into account both door opening methods and ensure that in different installation methods, the lock transmission assembly can maintain a sufficient distance from the frame of the lock body 100.

[0085] Optionally, in one embodiment, corresponding to the implementation mode in which the first transmission member 30 is a rack, the lock transmission assembly further includes a dial button 50; the dial button 50 is reciprocatably disposed on the support member 10 and abuts against the first transmission member 30 to drive the first transmission member 30 to move.

[0086] The dial button 50 may be provided with a protrusion to facilitate the user to dial. The support member 10 may be provided with a guide groove or other structure to provide a guiding function during the reciprocating motion of the dial button 50.

[0087] In application, the lock body connector 20 may be a polygonal cylinder; for example, the lock body connector 20 may be a square steel, so as to facilitate its transmission connection between the lock body 100 and the second transmission member 40. Correspondingly, the lock body 100 and the second transmission member 40 are provided with a polygonal hole 41 for the lock body connector 20 to be inserted into.

[0088] In one embodiment, see Figure 7The lock transmission assembly also includes a card plate 60; the card plate 60 can be movably arranged on the support member 10; the lock body connecting member 20 is inserted into the second transmission member 40 along the axial direction of the second transmission member 40; when installing the lock body connecting member 20, the lock body connecting member 20 can be moved along the axial direction of the second transmission member 40 until the lock body connecting member 20 is inserted into the second transmission member 40, specifically, the lock body connecting member 20 can be moved until it is inserted into the polygonal hole 41 described below.

[0089] The clamping plate 60 is used to clamp the lock body connector 20 to limit the axial movement of the lock body connector 20 along the second transmission member 40. That is, at this time, the lock body connector 20 is limited by the clamping plate 60 and cannot move along the axial direction of the lock body connector 20, so that the lock body connector 20 cannot be separated from the second transmission member 40 at this time.

[0090] After the lock body connector 20 is connected to any second transmission member 40, the lock body connector 20 can be axially fixed on the support member 10 through the clamping plate 60 to prevent the lock body connector 20 from moving in the axial direction, making the connection between the lock body connector 20 and the support member 10 more stable.

[0091] As an embodiment, the locking plate 60 can be connected to the lock body connecting member 20 in the following manner: the lock body connecting member 20 includes an inner shaft and an outer shaft; the inner shaft can be rotatably sleeved inside the outer shaft. The locking plate 60 is connected to the outer shaft, and the inner shaft connects the second transmission member 40 and the lock body; the locking plate 60 connected to the outer shaft can limit the separation of the lock body connecting member 20 from the support member 10, while not affecting the rotation of the lock body connecting member 20 following the second transmission member 40.

[0092] In another embodiment, the lock body connector 20 is provided with a slot 21; the card plate 60 is provided with a holding portion 61; the holding portion 61 is inserted into the slot 21, so that the card plate 60 holds the lock body connector 20. When the installation position of the lock body connector 20 needs to be changed, the card plate 60 is moved until the holding portion 61 is separated from the slot 21, that is, the card plate 60 is separated from the lock body connector 20, that is, at this time, the freedom of the lock body connector 20 in the axial direction is released, and the lock body connector 20 can be moved along the axial direction of the second transmission member 40 and taken out from the polygonal hole 41. The holding portion 61 can be, for example, a structure such as a convex block, so that when the two are engaged, the holding portion 61 can be engaged with the slot 21 to limit the axial freedom of the lock body connector 20.

[0093] In one embodiment, see Figures 8 to 10, the movable mode of the card plate 60 is rotation, that is, the card plate 60 can be rotatably arranged on the support member 10; when the card plate 60 is rotated so that the card slot 21 of the lock body connector 20 is engaged with the clamping portion 61, the card plate 60 can be fixedly installed on the support member 10; when disassembling, the card plate 60 can be loosened from the support member 10, and the card plate 60 can be rotated so that the lock body connector 20 is separated from the clamping portion 61. That is, the card plate 60 is semi-fixedly connected to the support member 10, and the rotational freedom of the card plate 60 is limited by loosening or locking, and during the disassembly process, the card plate 60 only needs to be rotated by a certain angle to facilitate the clamping fixation or separation freedom of the lock body connector 20. At the same time, the outer end of the clamping portion 61 can be a circular arc transition or a chamfered transition structure to facilitate the clamping of the lock body connector 20.

[0094] By providing the locking groove 21 on the lock body connecting member 20 , the rotation of the lock body connecting member 20 can be prevented from being affected when the locking plate 60 is engaged with the lock body connecting member 20 .

[0095] In one embodiment, the clamping portion 61 is an open slot structure; specifically, the opening direction of the clamping portion 61 is located on the rotation plane of the clamping plate 60. Figures 8 to 10 Taking the shown orientation as an example, after installing the card plate 60 and the lock body connector 20, rotating the card plate 60 clockwise can drive the holding portion 61 to gradually enter the card slot 21, so that the holding portion 61 and the card slot 21 are engaged; when the engagement needs to be released, rotating the card plate 60 counterclockwise can drive the holding portion 61 to gradually move away from the card slot 21, thereby releasing the engagement between the two.

[0096] Corresponding to the two second transmission members 40 , the clamping plate 60 may be provided with two clamping portions 61 ; the positions of the two clamping portions 61 correspond to the positions of the two second transmission members 40 ; the lock body connector 20 may be clamped in any one of the two clamping portions 61 .

[0097] Among them, the positions of the two clamping portions 61 correspond to the positions of the two second transmission members 40 respectively, which means that: when one clamping portion 61 is rotated to engage the clamping slot 21, the position of the other clamping portion 61 is aligned with the second transmission member 40 on which the lock body connecting member 20 is not installed. That is, assuming that both second transmission members 40 are installed with lock body connecting members 20, when one clamping portion 61 is rotated to engage the clamping slot 21 of one lock body connecting member 20, the other clamping portion 61 will engage with the clamping slot 21 of the other lock body connecting member 20.

[0098] By providing two clamping parts 61 corresponding to the second transmission member 40, the lock body connection member 20 can be matched with the clamping part 61 and fixed by the clamping plate 60 while selectively connecting to any second transmission member 40 according to the door opening direction. In addition, by providing the clamping plate 60 with two clamping parts 61, the lock body connection member 20 can be fixed at two matching positions, and the lock body connection member 20 can be fixed without designing connecting screws or other complex fixing structures for the lock body connection member 20, which has the effect of convenient disassembly and assembly.

[0099] Corresponding to the embodiment in which the clamping portion 61 is an open groove structure, the central axes of the two clamping portions 61 can correspond to the central axes of the two second transmission members 40, that is, when the clamping plate 60 is clamped to the lock body connector 20, the central axes of the two clamping portions 61 coincide with the central axes of the two second transmission members 40.

[0100] Optionally, a limiter 11 is provided on the support member 10 to limit the movable travel of the card plate 60. The limiter 11 can prevent the card plate 60 from excessively rotating and can also serve as a rotation direction prompt for the card plate 60. Figure 8 As shown, the limiting member 11 can be set at a diagonal position of the card plate 60. At this angle, the card plate 60 can be rotated to facilitate the removal of the lock body connector 20, while avoiding excessive rotation of the card plate 60.

[0101] See also Fig.10 In one embodiment, the limit member 11 includes a first limit member 13 and a second limit member 12; the first limit member 13 and the second limit member 12 are respectively arranged on both sides of the movable direction of the card plate 60, thereby respectively limiting the movable travel of the card plate 60 in two directions.

[0102] For example, in the present embodiment, when the card plate 60 abuts against the first limit member 13, the card plate 60 clamps the lock body connector 20; that is, the first limit member 13 is used to limit the movable travel of the card plate 60 in the direction of clamping the lock body connector 20, thereby preventing the card plate 60 from excessively moving and abutting against the lock body connector 20, causing difficulty in rotating the lock body connector 20.

[0103] When the card plate 60 abuts the second limiter 12, the lock body connector 20 can move along the axial direction of the second transmission member 40; that is, the second limiter 12 is used to limit the movable travel of the card plate 60 in the direction away from the lock body connector 20; in this embodiment, the card plate 60 is limited by the first limiter 13 and the second limiter 12 to a movable angle of less than 45°. The second limiter 12 can serve as a reminder for the staff, that is, when the card plate 60 rotates to abut the second limiter 12, it indicates that the card plate 60 has been staggered with the lock body connector 20 by enough space, allowing the lock body connector 20 to be installed and removed; if there is no second limiter 12, the card plate 60 may not be able to be fixed or the card plate 60 may rotate excessively to block the other polygonal hole 41, which makes it inconvenient for the staff to install and remove the lock body connector 20.

[0104] In application, the second position-limiting member 12 can be columnar; the card plate 60 is provided with an arc-shaped guide groove 62, and when the card plate 60 is rotated to separate the card plate 60 from the lock body connector 20, the second position-limiting member 12 will gradually slide into the guide groove 62. The cooperation between the second position-limiting member 12 and the guide groove 62 can limit, support and guide the card plate 60.

[0105] In one embodiment, the clamping plate 60 can be detachably connected to the support member 10 by tightening the bolts 63. After the lock body connector 20 is installed, the clamping plate 60 clamps the lock body connector 20, and by tightening the tightening bolts 63, the clamping plate 60 can be fixed to the support member 10, ensuring that the lock body connector 20 is firmly installed.

[0106] Optionally, the card plate 60 may be a central structure to facilitate installation of the card plate 60 .

[0107] The corresponding clamping plate 60 is a centrally symmetrical structure, and the tightening bolt 63 can be set at the center of the clamping plate 60. By adjusting the tightness of the tightening bolt 63 at the center of the clamping plate 60, the tightness of the connection between the clamping plate 60 and the support member 10 can be controlled, so as to cooperate with the position adjustment of the lock body connecting member 20; in other words, the tightening bolt 63 has the function of synchronously coordinating the fixed connection of the lock body connecting member 20.

[0108] When adjusting the position of the lock body connecting member 20, it is only necessary to slightly loosen the tightening bolt 63 to rotate the card plate 60 to limit the lock body connecting member 20. At this time, the card plate 60 can be rotated and the tightening bolt 63 is used as the rotation axis of the card plate 60; after the lock body connecting member 20 and the card plate 60 are aligned and clamped, the tightening bolt 63 can be tightened to achieve fixation, without the need for a complicated fixing structure design, and the fixing structure (card plate 60 and tightening bolt 63) is always connected to the support member 10 and is not easy to lose.

[0109] It should be noted that, during the rotation process of the clamping plate 60, the tightening bolt 63 is used as the rotation axis, and there is bound to be a gap between the tightening bolt 63 and the clamping plate 60, so the clamping plate 60 may shake relative to the support member 10 during the rotation process. To this end, in the embodiment provided by the present application, the shaking of the clamping plate 60 during the rotation process can also be reduced by the cooperation between the guide groove 62 on the clamping plate 60 and the second stopper 12.

[0110] The second aspect of the present application embodiment provides a door lock. Figures 1 to 11 , comprising: a lock body 100, a lock tongue 110 and any of the above lock transmission components. The support member 10 in the lock transmission component is integrated with the lock body 100, or the support member 10 in the lock transmission component is detachably arranged on the lock body 100.

[0111] A lock hole 120 is provided on the lock body 100 ; the lock body connecting member 20 in the lock transmission assembly extends into the lock hole 120 and is transmission-connected with the lock tongue 110 .

[0112] The door lock provided in this embodiment can adapt to both left-opening door bodies and right-opening door bodies by selecting the lock body connecting member 20 to connect different second transmission members 40, thereby improving the adaptability of the door lock.

[0113] A third aspect of an embodiment of the present application provides a smart door, comprising a door body and any one of the above-mentioned lock transmission components; the lock transmission component is arranged on the door body.

[0114] Regardless of whether the door body provided in this embodiment adopts the left-opening or right-opening method, it is possible to ensure that there is enough space between the lock transmission assembly and the door frame by changing the installation position of the lock body connecting part 20 in the lock transmission assembly, thereby avoiding mutual interference between the installation of the door body and the door frame.

[0115] The above are only preferred embodiments of the present application and are not intended to limit the present utility model. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
