Description

[Technical field]

[0001] The invention relates to an electronic lock structure capable of mechanical and electrical separation. [Background technology]

[0002] For safety reasons, electronic locks must have a one-button escape function to avoid being unable to escape due to power outages in emergency situations. Since the electronic control part of the electronic lock is unlocked through motor transmission, the motor is in a self-locking state when it is not powered on, and the clutch mechanism must be used to control the electromechanical separation so that the door handle or knob can unlock and realize the one-button escape function. The existing clutch mechanism has a complex structure and high production cost. Some are integrated in the motor and achieve clutch through the forward and reverse rotation of the motor. This method is prone to jamming or failure, and there are certain safety hazards. [Summary of the invention]

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an electromechanical separation lock body structure which is simple in structure and easy to install.

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 7As shown in the figure, an electromechanically separated lock body structure includes a housing 1. Inside the housing 1, there is a locking tongue assembly 2. The locking tongue assembly 2 is the main tongue, and one end can extend out of and retract into the housing 1. A locking tongue dial 3 that can rotate is provided inside the housing 1, and the locking tongue dial 3 can toggle the locking tongue assembly 2 to extend and retract. A fork is provided on the locking tongue dial 3, and a toggle groove for the fork to extend into is provided on the locking tongue assembly 2. A transmission piece 4 driven by a motor to rotate is rotatably provided on the locking tongue dial 3. A linkage piece 5 linked with the locking tongue dial 3 is provided on the locking tongue dial 3. The transmission piece 4 and the linkage piece 5 rotate relative to each other. The linkage piece 5 and the locking tongue dial 3 are fixed together by a positioning post and rotate together. The linkage piece 5 drives the locking tongue dial 3 to rotate, and the locking tongue dial 3 can also drive the linkage piece 5. A clutch device 6 that can disengage the transmission piece 4 and the linkage piece 5 so that the transmission piece 4 can drive the linkage piece 5 to rotate is provided between the transmission piece 4 and the linkage piece 5. The clutch device 6 disengages the power between the transmission piece 4 and the linkage piece 5, that is, the transmission and power separation of the transmission piece 4 and the linkage piece 5 is achieved through the clutch device 6. A rotating block 7 that can be driven by a handle to rotate and can toggle the clutch device 6 to separate the transmission piece 4 and the linkage piece 5 is rotatably provided on the locking tongue dial 3. A rotating dial 8 that can rotate relative to the locking tongue dial 3 idly and can toggle the locking tongue dial 3 to rotate when driven by a handle is provided on the locking tongue dial 3. In the initial design, when the linkage piece 5 drives the locking tongue dial 3 to rotate, the rotating dial 8 rotates idly relative to the locking tongue dial 3, but rotating the rotating dial 8 can drive the locking tongue dial 3. After the rotating block 7 drives the clutch device 6 to separate the transmission piece 4 and the linkage piece 5, the rotating dial 8 can toggle the locking tongue dial 3 to rotate under the drive of the handle. When the handle drives the rotating block 7 to rotate, the rotating block 7 will drive the clutch device 6 to separate the transmission piece 4 and the linkage piece 5. The linkage piece 5 and the locking tongue dial 3 can rotate freely. During the process of the handle driving the rotating block 7 to rotate, the rotating dial 8 also rotates a small angle relative to the locking tongue dial 3. At this time, the rotating dial 8 just toggles the locking tongue dial 3 to rotate. At the same time, the rotating dial 8 and the locking tongue dial 3 can rotate relative to each other idly by a certain distance. There is a certain idle space (that is, idle by a certain angle) between the rotating dial 8 and the locking tongue dial 3. In this way, when the locking tongue dial 3 is driven to rotate electrically, it will not drive the rotating dial 8, that is, it will not drive the handle to rotate, but the locking tongue dial 3 will rotate idly and will not drive the rotating dial 8. Inside the housing 1, a first return spring 11 that can drive the clutch device 6 to reset and a second return spring 12 that can drive the rotating block 7 to reset are provided. The first return spring 11 always moves the clutch device 6 in the direction of combining with the transmission piece 4. The second return spring 12 resets the rotating block 7 after rotation. Both the first return spring 11 and the second return spring 12 are tension springs.

[0023] The clutch device 6 is a clutch column, which is a cylinder. The transmission plate 4 is provided with a guide groove 41 for the clutch column to extend into and guide the clutch column to slide, and a clamping groove 42 connected to the guide groove 41 for the clutch column to clamp into. The guide groove 41 is an arc groove, and the clamping groove 42 is a U-shaped groove provided on the inner wall of one side of the middle of the arc groove. The linkage plate 5 is provided with a pull groove 51 for one end of the clutch column to penetrate into. The width of the pull groove 51 is roughly equivalent to the outer diameter of the clutch column. The length of the pull groove 51 is sufficient for the clutch column to move out of the clamping groove 42. The first return spring 11 pulls the clutch column to move to one side of the clamping groove 42. The rotating block 7 is provided with an escape groove 71 for one end of the clutch column to extend into. The escape groove 71 is an arc groove. The clutch column is pressed against the inner wall of the escape groove 71 under the action of elastic force. The escape groove 71 is provided with an inclined shifting wall 72 which can push the clutch column to slide out of the slot 42 when the rotating block 7 rotates. The inclined shifting wall 72 is on the left and right sides of the escape groove 71.

[0024] A groove 31 is provided in the bolt head 3, and the rotating head 8 can be relatively rotatably arranged in the groove 31. The rotating head 8 can idle at a certain angle in the groove 31. A rotating dial wall 32 is provided in the groove 31, which is driven by the rotating head 8 to drive the bolt head 3 to rotate. The rotating dial wall 32 is a convex, and the groove 31 is a circular groove. There are two rotating dial walls 32, and the two rotating dial walls 32 are 180° apart. The rotating dial head 8 has a convex head that can lean against one side of the rotating dial wall 32. There are two convex heads and they are 180° apart. The rotating dial head 8 rotates along the groove 31 until it rests against one side of the rotating dial wall 32. It needs to rotate a small angle (that is, after the transmission plate 4 and the linkage plate 5 are separated). In the initial position, the rotating dial head 8 can drive the lock tongue dial head 3, that is, when the rotating dial head 8 is driven by the handle, the rotating dial head 8 can drive the lock tongue dial head 3 to rotate, but when driven by the motor, that is, when the linkage plate 5 drives the lock tongue dial head 3, the lock tongue dial head 3 and the rotating dial head 8 are always in an idling state. When the rotating dial head 8 is reset, it can be driven to reset by the handle.

[0025] The transmission piece 4 and the linkage piece 5 are sleeved on the lower end of the bolt head 3, and the rotating block 7 is arranged on the upper end of the bolt head 3, that is, the transmission piece 4 and the linkage piece 5 are stacked on the lower end of the bolt head 3, and the rotating block 7 is stacked on the upper end of the bolt head 3. The transmission piece 4 and the linkage piece 5 have holes in the middle, and the bolt head 3 has a cylinder inserted into the transmission piece 4 and the linkage piece 5. The upper and lower ends of the rotating block 7 are respectively provided with an upper fixing piece 73 and a lower fixing piece 74, and the lower fixing piece 74 is a circular piece and can be relatively rotated and extended into the bolt head 3. The rotating block 7, the upper fixing piece 73, the lower fixing piece 74 and the rotating head 8 are respectively provided with a square hole 10 connected for inserting one end of the handle.

[0026] One end of the clutch column is provided with a fixing plate 13 fixed on the shell 1. The fixing plate 13 is arranged on the outer wall of the shell 1. The shell 1 is provided with a mounting hole 14 for the clutch column to penetrate. The clutch column can be inserted and installed from the outside of the lock shell 1. The structure is simple and the installation is convenient.

[0027] A transmission gear 15 driven by a motor is rotatably disposed in the housing 1 . A gear portion 43 meshing with the transmission gear 15 is disposed on the transmission plate 4 . After the motor is decelerated by a deceleration mechanism, the output gear of the deceleration mechanism meshes with the transmission gear 15 .

[0028] Figure 1 The position in is the position of the motor during the unlocking process, that is, the position where the transmission plate 4 and the linkage plate 5 just achieve transmission engagement. At this time, the clutch device 6 is combined with the transmission plate 4, so that the transmission plate 4 and the linkage plate 5 are dynamically coupled. Specifically, after the transmission plate 4 rotates a certain angle, the slot 42 is located at the position of the clutch column. Under the tension of the spring, the clutch column is inserted into the slot 42, and the transmission plate 4 and the linkage plate 5 rotate together. The linkage plate 5 will drive the lock tongue dial head 3 to rotate and drive the lock tongue assembly 2 (due to the effect of the rotating dial head 8, at this time, the transmission plate 4 and the linkage plate 5 rotate together to drive the lock tongue assembly 2, the lock tongue dial head 3 and the handle are in an idling state). When the lock tongue assembly 2 is extended or retracted in the housing 1, the motor stops working, the transmission plate 4 also stops, and the clutch column is in Figure 6 position, i.e. the electronically locked state, and when the electronically unlocked state, the clutch column is located at the leftmost position close to the air avoidance groove 71.

[0029] When opening manually, turn the handle to unlock. Figure 6 From the perspective of the position, the rotating piece 7 rotates, and the inclined dial wall 72 on the far right of the rotating piece 7 will dial the clutch column, thereby driving the clutch column to slide out of the card slot 42, and the transmission piece 4 and the linkage piece 5 will be in a separated state. The handle drives the lock tongue dial head 3 and the linkage piece 5 to rotate together by rotating the dial head 8, thereby driving the lock tongue assembly 2 to unlock. Under the action of the reset force of the spring, the transmission piece 4, the linkage piece 5, the clutch column, and the rotating piece 7 are all reset. The reset position is as shown in FIG. Figure 7 As shown, after manual unlocking, no matter the bolt assembly 2 is in the extended or retracted state, the transmission plate 4, the linkage plate 5, the clutch column, and the rotating plate 7 are all reset. Figure 7 The transmission plate 4 and the linkage plate 5 are in the separated state.
