As shown in fig. 1 to 5, an electronic lock 200 according to an embodiment of the present invention includes a housing 210, a clutch device 100, a motor 250 disposed in the housing 210, an outer shaft driving wheel 230 disposed in the housing 210, and a lock cylinder 170.
The clutch device 100 comprises a clutch 110, a clutch deflector 120 movably arranged on a shell 210 of the electronic lock 200 and fixedly connected with the clutch 110, an inner shaft clutch wheel 130, a clutch pin assembly 140, an emergency deflector 150 movably arranged on the shell 210 of the electronic lock 200 and an emergency sheave 160 rotatably arranged in the shell 210.
It should be noted that fig. 1 to 3 are partial schematic structural diagrams of the electronic lock 200, so the housing 210 is also a partial schematic structural diagram, and is not shown completely, but does not affect the integrity of the technical solution of the present disclosure.
Wherein the clutch lever 120 has an abutment surface 121. The inner clutch pulley 130 has a socket 131.
The clutch pin assembly 140 includes a clutch pin 141 movably provided on the outer driving wheel 230 of the electronic lock 200 and an elastic member 143 provided on the outer driving wheel 230. One end of the clutch pin 141 is abutted against the abutting surface 121 of the clutch lever 120 under the elastic force of the elastic member 143, and the other end of the clutch pin can be inserted into the slot 131 under the pushing action of the clutch lever 120, so that the inner shaft clutch wheel 130 is linked with the outer shaft driving wheel 230 of the electronic lock 200, and the electronic lock 200 can be opened or locked by rotating the handle.
The side wall of the emergency sheave 160 is provided with a groove 161 which extends in a direction not to be co-directional with the axial direction of the emergency sheave 160 and the radial direction of the emergency sheave 160. The emergency dial 150 is provided with an insert 151 that mates with the recess 161. Groove 161 includes a first lock point 163 located at the beginning of groove 161, a second lock point 165 located at the middle of groove 161, and a third lock point 167 located at the end of groove 161. The first lock point 163 and the third lock point 167 are located on the side of the second lock point 165 remote from the clutch pin 141. The spacing between the first lock point 163 and the second lock point 165 in the axial direction of the emergency sheave 160 is smaller than the spacing between the second lock point 165 and the third lock point 167 in the axial direction of the emergency sheave 160.
The emergency sheave 160 rotates such that the insert 151 moves from the first lock point 163 to the second lock point 165 relative to the groove 161 and from the second lock point 165 to the third lock point 167 relative to the groove 161. Specifically, in this embodiment, the operator uses the key 180 to drive the rotation of the emergency sheave 160 through the lock cylinder 170.
The clutch device 100 has an engaged state, a disengaged state, and an intermediate state, and the clutch device 100 is switchable between the intermediate state and the engaged state, and between the engaged state and the disengaged state
When the clutch device 100 is in the neutral state, the insert 151 is located at the first lock point 163 of the recess 161. At this time, the clutch lever 120 may move relative to the emergency dial 150. The clutch 110 can be inserted into the slot 131 of the inner clutch pulley 130 by pushing the clutch pin 141 by the clutch lever 120. In other words, the intermediate state of the clutch device 100 is the empty state of the key 180, i.e. the key is not inserted into the lock core 170, so that the emergency sheave 160 is not driven to rotate, and the emergency dial 150 is not driven to move. At this time, the clutch 110 drives the clutch lever 120 to move, so as to control the clutch pin 141 to be inserted into or pulled out of the slot 131 of the inner clutch wheel 130.
The emergency sheave 160 is driven to rotate by the key 180 through the lock cylinder 170, the insert 151 moves from the first lock point 163 to the second lock point 165 relative to the groove 161, so that the emergency poking plate 150 moves relative to the housing 210 of the electronic lock 200 and drives the clutch poking rod 120 to move so as to push the clutch pin 141 to be inserted into the slot 131 of the inner shaft clutch wheel 130, and the clutch device 100 is in a combined state. At this time, the clutch lever 120 cannot move relative to the housing 210 of the electronic lock 200.
Continuing to use the key 180 to drive the emergency sheave 160 to rotate through the lock core 170, the insert 151 moves from the second lock point 165 to the third lock point 167 relative to the groove 161, the emergency shifting plate 150 moves relative to the housing 210 of the electronic lock 200 and drives the clutch shifting lever 120 to move, and the clutch pin 141 is pulled away from the slot 131 of the inner shaft clutch wheel 130 under the elastic force of the elastic member 143, so that the clutch device 100 is in a separated state. At this time, the clutch lever 120 cannot move relative to the housing 210 of the electronic lock 200.
Therefore, when the clutch device 100 cannot be coupled due to damage or no power supply when the clutch device 100 is in the intermediate state, the clutch device 100 can be in the coupled state by controlling the rotation of the emergency sheave 160, so that the lock body of the electronic lock 200 can be in the locked state. Further, the locking of the electronic lock 200 is completed by controlling the rotation of the emergency sheave 160 so that the clutch device 100 is in a disengaged state. I.e. by means of mechanical operation, the locking problem of the electronic lock 200 is achieved.
Of course, the clutch device 100 can also realize the unlocking problem of the electronic lock 200. Specifically, when the electronic lock 200 is in the locked state, if the clutch device cannot be automatically engaged, the key 180 may be used to control the movement of the emergency sheave 160 through the lock core 170, so that the clutch device 100 is in the engaged state. At this time, the unlocking problem of the electronic lock 200 can be achieved by rotating the handle.
In this embodiment, the emergency dial 150 is provided with a first limiting portion 153, and the clutch lever 120 is provided with a first limiting groove 123 matching the first limiting portion 153. Specifically, the first limiting groove 123 extends along the direction in which the clutch lever 120 moves, and has a first end 1231 that is close to the clutch pin 141 and a second end 1233 that is far from the clutch pin 141. The first limiting portion 153 is slidable in the first limiting groove 123.
When the clutch device 100 is in the intermediate state, the first limiting portion 153 is located at the first end 1231 of the first limiting groove 123. When the clutch device 100 is in the disengaged state, the first limiting portion 153 is located at the second end 1233 of the first limiting groove 123.
The clutch device 100 is set to be in a process of switching from the intermediate state to the engaged state, the maximum distance that the clutch lever 120 moves is L1, that is, the distance that the clutch pin 141 moves from the state of completely withdrawing from the slot 131 to the state of completely inserting into the slot 131 is L1, and similarly, the clutch 110 is fixedly connected to the clutch lever 120, so that the maximum distance that the clutch 110 moves is L1. The distance that the emergency dial 150 moves, that is, the distance between the second lock point 165 and the third lock point 167 along the axial direction of the emergency sheave 160 is L2, is set in the process of switching the clutch device 100 from the engaged state to the disengaged state.
In order to meet the requirement that the clutch device 100 is in the intermediate state, the clutch 110 can drive the clutch lever 120 to move, so as to control the clutch pin 141 to be inserted into or pulled out of the slot 131 of the inner clutch wheel 130, the distance from the first end 1231 to the second end 1233 of the first limiting groove 123 of the first limiting portion 153 is greater than or equal to L1. Furthermore, in order to meet the transition of the clutch device between the intermediate state, the engaged state and the disengaged state, L2.gtoreq.2XL1 is required.
Preferably, in the present embodiment, the first limiting portion 153 moves from the first end 1231 to the second end 1233 of the first limiting groove 123 by a distance=l1, l2=2×l1. Accordingly, the first lock point 163 is spaced from the second lock point 165 by a distance L1 in the axial direction of the emergency sheave 160. In this way, the clutch device 100 can be switched between three states by moving the emergency shifting plate 150 by a small distance, friction between the insert 151 and the groove 161 is reduced, and the service life of the emergency shifting plate 150 and the emergency sheave 160 is prolonged.
The radial angle of the groove 161 between the first lock point 163 and the second lock point 165 is set to a, and the radial angle of the groove 161 between the second lock point 165 and the third lock point 167 is set to b. In this embodiment, a+b=360°, thereby effectively avoiding deformation of the emergency sheave due to only local stress.
Preferably, in this embodiment, b= 2*a =240°. In this way, it is ensured that the distance that the emergency dial 150 moves is the same when the emergency sheave 160 rotates by the same angle. And the emergency sheave 160 drives the emergency dial 150 to move at a certain speed, the side walls of the grooves 161 at various positions exert the same stress on the insert 151. The occurrence of the phenomenon that the grooves 161 are severely worn locally is avoided.
In this embodiment, at least one through slot 125 is provided on each of the clutch lever 120 and the emergency dial 150, and the through slot 125 extends along the direction in which the clutch lever 120 moves. A fixing pin 211 matched with the through groove 125 is fixedly arranged on the shell 210 of the electronic lock 200. The fixing pin 211 is movable in the through groove 125 in a direction in which the through groove 125 extends.
Of course, the fixing pin 211 may be replaced by other parts that can move in the through slot 125, such as a fixing post.
In this embodiment, the clutch pin assembly 140 further includes a fixing frame 145 fixedly provided on the outer driving wheel 230 of the electronic lock 200. The end of the fixing frame 145, which is far away from the contact surface 121 of the clutch lever 120, is provided with a first step portion, and the clutch pin 141 is provided with a second step portion, wherein the second step portion is located on one side of the first step portion, which is close to the contact surface 121 of the clutch lever 120. One end of the elastic member 143 abuts the first step portion, and the other end abuts the second step portion. In this embodiment 143 is a spring.
In this embodiment, the clutch 110 is provided with a second limiting portion 111, and the clutch lever 120 is provided with a second limiting groove 127 in interference fit with the second limiting portion 111, so as to fixedly connect the clutch 110 and the clutch lever 120.
When the clutch device for the electronic lock is damaged or has no power supply and the like in the middle state, the clutch device can be in a combined state by controlling the rotation of the emergency grooved wheel, so that the lock body of the electronic lock can be in a locking state; the clutch device is in a separated state by further controlling the rotation of the emergency grooved wheel so as to complete the locking of the electronic lock. Namely, the locking problem of the electronic lock is realized by a mechanical operation mode.
The electronic lock comprises the clutch device provided by the invention, and the locking problem of the electronic lock can be realized in a mechanical operation mode.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
