Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a switch lock mechanism and a lock. Background Art

[0002] In the related art, to meet different door opening and closing requirements, some locks are equipped with both mechanical lock cylinder and electric lock release mechanisms. These locks typically consist of a front lock body, a rear lock body, and a connecting rod. One end of the connecting rod connects to the rear lock body, while the other end can engage and disengage with the front lock body.

They are only for the convenience of describing the present invention 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. Therefore, they cannot be understood as limitations on the present invention.

[0028] In the present invention, unless otherwise expressly defined, terms such as "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection; and internal communication between two components or interaction between two components. Those skilled in the art can reasonably determine the specific meanings of these terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figures 1 to 4 A switch lock mechanism according to an embodiment of the present invention includes: a connecting rod 100, one end of which is used to be fixedly connected to the rear lock body, and the other end extends to the front lock body 20, and a first clutch portion 110 is provided on the side of the end of the connecting rod 100 extending to the front lock body 20; a mechanical lock core 200, the mechanical lock core 200 includes a lock shell sleeve 210 for being fixed to the front lock body 20 and a core body 220 rotatably arranged on the lock shell sleeve 210, the core body 220 and the connecting rod 100 are coaxial and can rotate relative to each other; a transmission mechanism 300, which is provided between the core body 220 and the connecting rod 100 and can drive the core body 220 and the connecting rod 100 to rotate together; an electric unlocking mechanism 400, which is fixed to the front lock body 20, and the output end of the electric unlocking mechanism 400 can be combined with or separated from the first clutch portion 110.

[0030] When the key is inserted into the mechanical lock cylinder 200 to unlock, the core body 220 rotates relative to the lock shell 210. During the rotation process, the core body 220 can use the transmission mechanism 300 to drive the connecting rod 100 to rotate together, so that the front lock body 20, the connecting rod 100 and the rear lock body rotate together to unlock the lock tongue; when the electric unlocking mechanism 400 is used to unlock, the output end of the electric unlocking mechanism 400 is combined with the first clutch part 110, and the front lock body 20, the connecting rod 100 and the rear lock body rotate together to unlock the lock tongue, wherein the connecting rod 100 It can rotate relative to the core 220 within a certain angle range. When the key is not inserted, the core 220 cannot rotate. Therefore, the connecting rod 100 does not touch the core 220 when rotating within a certain angle range, which can avoid the connecting rod 100 from getting stuck. The connecting rod 100 and the core 220 of the above switch lock mechanism can interact directly, eliminating the traditional partial clutch structure between the core 220 and the connecting rod 100. The production, processing and assembly difficulty of the switch lock mechanism are relatively low, and the working reliability is relatively high.

[0031] See also Figure 1 、 Figure 2 and Figure 4 In some embodiments of the present invention, the first clutch portion 110 is a socket formed on the sidewall of the connecting rod 100, and the electric unlocking mechanism 400 is a linear actuator. The output end of the linear actuator is provided with a plug-in post 410 that can extend into or out of the socket. It is understood that the linear actuator drives the plug-in post 410 into the socket, thereby connecting the front lock body 20 and the connecting rod 100. Unlocking can be achieved by rotating the front lock body 20. When the linear actuator drives the plug-in post 410 out of the socket, the front lock body 20 cannot rotate with the connecting rod 100, thus preventing unlocking. The above electric unlocking mechanism 400 has a very simple structure and low cost. In this embodiment, the linear actuator is an electric push rod, and the rod portion of the electric push rod serves as the plug-in post 410. Of course, in other embodiments, the linear actuator can be a linear motor.

[0032] See also Figure 1 and Figure 2In some embodiments of the present invention, a sleeve 500 is provided at the end of the core 220, and the connecting rod 100 has a shaft portion 120 that passes through the sleeve 500. The shaft portion 120 is provided with a turntable portion 130 that can rotate within the sleeve 500. The transmission mechanism 300 includes a transmission column 310 provided on the core 220 and a first stop portion 320 provided on the turntable portion 130. The transmission column 310 can abut against the first stop portion 320 to drive the connecting rod 100 and the core 220 to rotate together. It should be noted that the internal space of the sleeve 500 can accommodate the transmission mechanism 300, provide space for the turntable portion 130 to rotate, and prevent the connecting rod 100 from moving away from the sleeve 500, which would cause the transmission mechanism 300 to fail. When the key is inserted into the core 220, the lock housing 210 is fixed to the front handle housing 22, allowing the core 220 to rotate relative to the lock housing 210. The transmission column 310, following the rotation of the core 220, can abut against the first stop 320, thereby causing the core 220 to rotate with the connecting rod 100. When the electric unlocking mechanism 400 is used to unlock the door, the output end of the electric unlocking mechanism 400 engages with the first clutch 110. When the front lock body 20 and the connecting rod 100 rotate together to unlock the door, the first stop 320 moves away from the transmission column 310. Therefore, when the electric unlocking mechanism 400 is used to unlock the door, the connecting rod 100 does not interfere with the core 220.

[0033] See also Figure 1 and Figure 2 In some embodiments of the present invention, the turntable portion 130 is provided with a second stop portion 330 spaced apart from the first stop portion 320. A space is defined between the first stop portion 320 and the second stop portion 330, allowing the transmission column 310 to freely rotate. It is understood that, depending on the unlocking rotation direction, the transmission column 310 can abut against the first stop portion 320 to unlock, or against the second stop portion 330 to unlock. This space prevents interference between the connecting rod 100 and the core 220 when the electric unlocking mechanism 400 is unlocked. Specifically, in this embodiment, when the front lock body 20 needs to rotate clockwise to unlock, the transmission column 310 abuts against the first stop portion 320 and rotates clockwise to unlock. When the front lock body 20 needs to rotate counterclockwise to unlock, the transmission column 310 abuts against the second stop portion 330 and rotates counterclockwise to unlock.

[0034] See also Figure 2In some embodiments of the present invention, the turntable portion 130 includes a circular portion 131 protruding radially from the shaft portion 120 and a sector ring portion 132 disposed on the outer circumferential wall of the circular portion 131. The two end surfaces of the sector ring portion 132 respectively constitute the first stop portion 320 and the second stop portion 330. Specifically, the circular portion 131 and the sector ring portion 132 are integrally formed with the turntable portion 130. The two end surfaces of the sector ring portion 132 respectively constitute the first stop portion 320 and the second stop portion 330, which facilitates simplifying the structure of the switch lock mechanism and reducing the production and assembly processes.

[0035] See also Figure 2 and Figure 4 In some embodiments of the present invention, the inner circumferential wall of the sleeve 500 is provided with an internal thread 510, and the core 220 is provided with an external thread 221 connected to the internal thread 510. The sleeve 500 is provided with a through hole for the shaft portion 120 to extend therethrough. The contour edge of the through hole is provided with a plurality of positioning grooves 520 corresponding to the transmission posts 310. The transmission posts 310 can elastically extend along the length of the core 220 to engage with one of the positioning grooves 520, thereby preventing the sleeve 500 from rotating relative to the core 220. The sleeve 500 and the core 220 are connected by a threaded connection for ease of assembly and production. When the transmission posts 310 and the positioning grooves 520 engage, they prevent the sleeve 500 from rotating relative to the core 220, thereby preventing the sleeve 500 from falling off the core 220 and ensuring that the turntable portion 130 can rotate stably within the sleeve 500.

[0036] See also Figure 1 Figure 2 and Figure 4 In some embodiments of the present invention, a limiting ring 600 is movably provided on the shaft portion 120. The limiting ring 600 is located inside the sleeve 500 and abuts against the side of the turntable portion 130. The limiting ring 600 is provided with a notch groove 610 for the transmission column 310 to pass through. It can be understood that during assembly, the through-shaft portion 120 is first extended into the sleeve 500 along the through hole, and then the limiting ring 600 is inserted into the through-shaft portion 120, and then the turntable portion 130 is fixedly connected to the through-shaft portion 120 to prevent the limiting ring 600 from falling out, and then the transmission column 310 on the core body 220 is passed through the notch groove 610, and then pressure is applied along the length direction of the transmission column 310 to make the transmission column 310 leave the positioning groove 520. At this time, the transmission column 310 is still located in the notch groove 610. By rotating the core body 220 until the core body 220 and the sleeve 500 are screwed together, and then loosening the transmission column 310, the transmission column 310 can be elastically reset to enter one of the positioning grooves 520.

[0037] It should be noted that the retaining ring 600 abutting the side of the rotating disk portion 130 helps prevent the connecting rod 100 from moving relative to the sleeve 500 along its length, and the transmission post 310 being located in the notch 610 helps prevent the transmission post 310 from twisting and deforming. In this embodiment, multiple positioning grooves 520 are circumferentially arranged around the contour edge of the through hole, so that the transmission post 310 can enter one of the positioning grooves 520, thereby ensuring that the sleeve 500 can be stabilized after being rotated to a certain angular position on the core 220.

[0038] See also Figure 3 and Figure 4 The present invention also discloses a lock comprising a switch lock mechanism according to any of the above technical solutions. This lock employing the switch lock mechanism achieves both mechanical and electric unlocking functions with a simple structure. The lock is relatively easy to manufacture, process, and assemble, and exhibits high operational reliability.

[0039] See also Figure 3 and Figure 4 In some embodiments of the present invention, the front lock body 20 and the rear lock body are configured such that the front lock body 20 includes a front fixed seat 21 and a front handle cover 22 rotatably mounted on the front fixed seat 21. The mechanical lock cylinder 200, the transmission mechanism 300, and the electric unlocking mechanism 400 are all located within the front handle cover 22. The keyhole of the mechanical lock cylinder 200 is located on the front end of the front handle cover 22. A movable cover 700, which can be removably mounted on the front end of the front handle cover 22 and can be used to cover or reveal the keyhole, is provided on the movable cover 700. The movable cover 700 is provided with an identification control module 710 electrically connected to the electric unlocking mechanism 400. The movable cover 700 shields the keyhole, preventing dust accumulation within the keyhole and enhancing its concealment, thereby improving the security of the lock. The identification control module 710 can be used to unlock the lock if the user forgets their keys.

[0040] See also Figure 3 and Figure 4 In some embodiments of the present invention, the movable cover 700 is pivotally mounted on the front end of the front handle cover 22 via a pivot member 720. The identification control module 710 includes a password dial mounted on the movable cover 700. The user can control the electric unlocking mechanism 400 to unlock the door by entering a password. In other embodiments, the identification control module 710 can be replaced by a fingerprint recognition device or an access card recognition device, which will not be further described here.
