Description

Technical Field

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0039] The utility model provides an electronic lock front panel.

[0040] In the embodiment of the present utility model, Figures 1 to 14 As shown, the front panel of the electronic lock includes a shell 10, a clutch mechanism 20 and a handle 30. The shell 10 is provided with a mounting hole 11 and two first limiting portions 12 respectively arranged on opposite sides of the mounting hole 11; the clutch mechanism 20 includes a clutch seat 21 rotatably mounted at the mounting hole 11, the clutch seat 21 is provided with a limiting protrusion 211 extending toward the side, the limiting protrusion 211 rotates between the two first limiting portions 12 as the clutch seat 21 rotates, and has a first state abutting against one of the first limiting portions 12, a second state abutting against the other first limiting portion 12 and a third state spaced between the two first limiting portions 12; the handle 30 is connected to the clutch seat 21 and is located outside the shell 10. When the limiting protrusion 211 is in the third state, the handle 30 is in a reset state.

[0041] In this embodiment, the front panel of the electronic lock further includes a main control board, which is electrically connected to a driving member of the clutch mechanism 20 to control the driving member to drive the clutch mechanism 20 to move.

[0042] The two first position-limiting portions 12 are disposed on opposite sides of the mounting hole 11, which means that the two first position-limiting portions 12 are approximately located on opposite sides of the mounting hole 11, and it is not limited to the situation that the two first position-limiting portions 12 and the center of the mounting hole 11 are on the same straight line. That is, the line connecting the two first position-limiting portions 12 and the center point of the mounting hole 11 can be a straight line, a fold line with an angle less than 180°, or a fold line with an angle greater than 180°.

[0043] The handle 30 is relatively fixed to the clutch seat 21. When the handle 30 is in the reset state, that is, the handle 30 is in a free state, when the front panel of the electronic lock is installed on the door body, the handle 30 can be in a horizontal state or a vertical state. Generally speaking, the handle 30 can be rotated clockwise or counterclockwise in the reset state. By rotating the handle 30 in one direction, the lock can be unlocked, and by rotating it in the opposite direction, the reverse lock can be achieved. When the clutch seat 21 is driven by the handle 30 to rotate until the limit protrusion 211 abuts against the first limit portion 12, the clutch seat 21 can be restricted from continuing to rotate, thereby achieving limit protection.

[0044] The technical solution of the utility model is that two first limiting portions 12 are provided on opposite sides of the mounting hole 11 of the shell 10, and a limiting protrusion 211 extending toward the side is provided on the clutch seat 21 of the clutch mechanism 20. After the clutch seat 21 is rotatably installed at the mounting hole 11, the limiting protrusion 211 is located between the two first limiting portions 12, so that when the limiting protrusion 211 moves between the two first limiting portions 12 with the rotation of the clutch seat 21, it has a first state of abutting against one of the first limiting portions 12, a second state of abutting against the other first limiting portion 12, and a third state of being located between the two first limiting portions 12. Such an arrangement can make the distance between the two first limit parts 12 farther, that is, the travel of the limit protrusion 211 from the third state to the first state and the second state is longer, so that the rotation angle of the clutch seat 21 and the handle 30 can be larger, and the maximum rotation angle of the handle 30 can exceed 120°, that is, it can be suitable for lock bodies with conventional unlocking angles, and can also be suitable for lock bodies with large angle unlocking, which greatly improves the application range of the front panel of the electronic lock.

[0045] In some embodiments, the clutch mechanism 20 further includes a torsion spring 22, two second limiting portions 217 are provided on the circumferential side of the clutch seat 21, and the two second limiting portions 217 are spaced apart along the circumference of the clutch seat 21, two third limiting portions 13 are provided on one side of the mounting hole 11 in the housing 10, and the two third limiting portions 13 are spaced apart along the circumference of the mounting hole 11 and are arranged corresponding to the positions of the two second limiting portions 217, the torsion spring 22 is sleeved on the clutch seat 21, and both ends of the torsion spring 22 are provided with abutment sections 221 extending radially outward, and the two abutment sections 221 extend between the two third limiting portions 13 through the space between the two second limiting portions 217. Specifically, the third limiting portion 13 and the first limiting portion 12 are staggered in the hole depth direction of the mounting hole 11, that is, in the hole depth direction of the mounting hole 11, the third limiting portion 13 is closer to the mounting hole 11 than the first limiting portion 12.

[0046] When the handle 30 is in the reset state, the opening between the two second limiting portions 217 corresponds to the opening between the two third limiting portions 13. At this time, the abutting section 221 at one end of the torsion spring 22 abuts against one of the third limiting portions 13 or the second limiting portion 217, and the abutting section 221 at the other end of the torsion spring 22 abuts against the other third limiting portion 13 or the second limiting portion 217. When the clutch seat 21 is driven to rotate by the handle 30, the second limiting portion 217 at the rear side of the clutch seat 21 in the rotation direction pushes the corresponding abutting section 221 to move toward the relative third limiting portion 13. At this time, the abutting section 221 at the other end of the torsion spring 22 is limited by the third limiting portion 13, so that the two abutting sections 221 gradually move closer, and the torsion spring 22 is compressed at this time. When the handle 30 is released, the handle 30 and the clutch seat 21 can be reset under the action of the torsion spring 22, so that the handle 30 moves to the reset state.

[0047] By sleeved the torsion spring 22 on the clutch seat 21, the torsion spring 22 can be made to fit as closely as possible outside the clutch seat 21, so that the overall structure of the clutch seat 21 and the torsion spring 22 is relatively compact, and the space occupied by the clutch seat 21 and the torsion spring 22 as a whole in the radial direction of the clutch seat 21 can be reduced, that is, the space occupied by the clutch seat 21 and the torsion spring 22 as a whole in the width direction of the electronic seat front panel can be reduced, thereby reducing the width of the electronic lock front panel, so that the electronic lock front panel can be better used on a door body with a narrow frame, which can further enhance the application range of the electronic lock front panel.

[0048] In some embodiments, the clutch mechanism 20 further includes a shift fork 23, a locking pin 24 and a driving assembly 25. The clutch seat 21 is provided with a connecting hole 212 and a through hole 213. The connecting hole 212 is provided at one end of the clutch seat 21 facing away from the handle 30. The through hole 213 penetrates the hole wall of the connecting hole 212 and the outer peripheral surface of the clutch seat 21. A convex rib 214 is provided in the connecting hole 212. The convex rib 214 and the through hole 213 are spaced apart in the circumferential direction of the connecting hole 212.

[0049] The first end of the shift fork is rotatably mounted in the connecting hole 212, the end surface of the first end is spaced apart from the through hole 213, a stopper 231 is convexly provided at the edge of the end surface of the first end, the stopper 231 is located between the through hole 213 and the convex rib 214, and the second end of the shift fork is provided with a square shaft hole 232 for connecting the square shaft;

[0050] The lock pin 24 is movably installed in the through hole 213, and the driving assembly 25 is located on the outside of the clutch seat 21. The driving assembly 25 is used to drive the lock pin 24 to move between the first position and the second position. When the lock pin 24 is in the first position, the lock pin 24 partially extends into the connecting hole 212 to limit the block 231 together with the rib 214, so that the clutch seat 21 and the shift fork can rotate synchronously. When the lock pin 24 is in the second position, the lock pin 24 partially withdraws from the connecting hole 212, so that the clutch seat 21 can rotate relative to the shift fork.

[0051] Specifically, the shift fork is cylindrical, wherein the end inserted into the connection hole 212 is the first end, and the end exposed outside the connection hole 212 is the second end. The convex rib 214 is located on the path of the block 231 when the shift fork rotates in the connection hole 212. When the lock pin 24 is in the first position, the lock pin 24 partially extends into the connection hole 212, and is now restricted between the lock pin 24 and the convex rib 214. Taking the handle 30 in the reset state and being horizontally placed as an example, at this time, by pressing down the handle 30, the block 231 can be abutted against the lock pin 24, so that the clutch seat 21 and the shift fork can be driven to rotate synchronously through the handle 30, thereby achieving unlocking. When the lock pin 24 is in the second position, the lock pin 24 partially exits the connection hole 212, and at this time, there is no obstruction of the lock pin 24. When the handle 30 is pressed down, the clutch seat 21 can rotate relative to the shift fork, so that unlocking cannot be achieved when closing the door. When the handle 30 is lifted, the block 231 can always abut against the rib 214, so that the clutch seat 21 and the shift fork can be driven to rotate synchronously in the opposite direction through the handle 30, thereby realizing functions such as reverse locking. This clutch method of the lock pin 24, the rib 214 and the block 231 has a simple structure, and can reduce the volume of the clutch seat 21 and the shift fork, thereby reducing the width of the front panel of the electronic lock.

[0052] In some embodiments, the driving assembly 25 is located below the clutch seat 21 and has a push member 251 that can move up and down. The push member 251 has a cylindrical surface 252 on one side facing the clutch seat 21. The axis of the cylindrical surface 252 is located in the connecting hole 212, and the lock pin 24 abuts against the cylindrical surface 252. In this way, when unlocking, the lock pin 24 can be ensured to be always in the first position, ensuring smooth unlocking.

[0053] In some embodiments, the locking pin 24 has a limiting shoulder 241, and the through hole 213 is provided with a limiting ring 215, and the limiting shoulder 241 is limited to the side of the limiting ring 215 away from the connecting hole 212. This can prevent the locking pin 24 from completely entering the connecting hole 212, ensuring structural reliability.

[0054] In some embodiments, an annular baffle 216 is provided on the circumferential side of the clutch seat 21, and a portion of the annular baffle 216 is spaced apart from the outer circumferential surface of the clutch seat 21 to form a receiving space, and the torsion spring 22 is located in the receiving space, and the annular baffle 216 has a notch, and two second limiting portions 217 are formed on opposite sides of the notch. Specifically, the annular baffle 216 protects the torsion spring 22, preventing the torsion spring 22 from contacting the housing 10 when deforming and displacing, and the structure of forming the second limiting portions 217 on both sides of the notch of the annular baffle 216 is simple and reliable.

[0055] In some embodiments, the front panel of the electronic lock further includes a fingerprint recognition module 41, which is mounted on the housing 10. Compared with the case where the fingerprint recognition module 41 is arranged on the handle 30, it is possible to avoid setting a wire structure on the handle 30 and the clutch seat 21, thereby improving the compactness of the structure of the handle 30 and the clutch seat 21, and further reducing the width of the front panel of the electronic lock. Optionally, the front panel of the electronic lock further includes a password input module 42, which is arranged on the housing 10; this makes it convenient for the user to input the seal to start when the fingerprint recognition module 41 fails. Optionally, the password input module 42 is located above the handle 30, and the fingerprint recognition module 41 is located above the password input module 42. This makes it easier for the user to operate.

[0056] In some embodiments, the front panel of the electronic lock further includes a mounting seat 51 and a bearing 52, the bearing 52 is sleeved on the clutch seat 21 and is located outside the housing 10, and the mounting seat 51 is sleeved outside the bearing 52 and fixed to the housing 10. Such a configuration can improve the rotation stability of the handle 30, and the mounting seat 51 and the bearing 52 are arranged outside the housing 10, which can reduce the thickness and width of the housing 10, and can further reduce the width of the front panel of the electronic lock.

[0057] In some embodiments, the handle 30 is provided with a fixing hole 31, the clutch seat 21 is inserted into the fixing hole 31 for fixing, and the electronic lock front panel further includes a sealing ring 60, one end of the sealing ring 60 extends to the inner ring of the bearing 52, and the other end extends between the clutch seat 21 and the inner wall of the fixing hole 31, and the outer peripheral surface of the sealing ring 60 is provided with a surrounding annular convex rib 61214, and the annular convex rib 61214 extends to the inner wall of the mounting seat 51. In this way, the sealing between the handle 30, the clutch seat 21 and the bearing 52 can be improved, thereby improving the service life of the electronic lock front panel.

[0058] The utility model also proposes an electronic lock, which includes a lock body and an electronic lock front panel. The specific structure of the electronic lock front panel refers to the above embodiment. Since the electronic lock adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. When in use, the lock body is installed in the door body or on the rear side of the door body, the electronic lock front panel is installed on the outside of the door body, and the shift fork of the electronic lock front panel cooperates with the lock body through a square shaft. Optionally, the electronic lock also includes a rear panel, which is installed on the rear side of the door body and cooperates with the lock body.
