Detailed Implementation

[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0035] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0036] On the one hand, refer to Figure 1 and Figure 2 This invention provides an electronic lock mechanism, including a housing 100, a first panel assembly 110 and a second panel assembly 120, a first operating handle 130 on the first panel assembly 110 and a second operating handle 140 on the second panel assembly 120, the first panel assembly 110 and the second panel assembly 120 being connected to form a first operating cavity 150; an electronic lock 200, which is installed inside the first operating cavity 150 and connected to the first operating handle 130 and the second operating handle 140 respectively; and a clutch mechanism 210, which is disposed inside the second panel assembly 120 and connected to the electronic lock 200, the clutch mechanism 210 including a drive unit 220 and a motor 230, the drive unit 220 being connected to the motor 230, and the drive unit 220 including a push block 221 and a second operating cavity 222. The second operating cavity 222 is equipped with a rotating rod 2221, a first spring 2222, a second spring 2223, and a slider 2224. One end of the push block 221 is connected to the second operating handle 140, and the other end of the push block 221 is connected to one end of the first spring 2222. The other end of the first spring 2222 is connected to one end of the slider 2224, and the other end of the slider 2224 is connected to the second spring 2223. The other end of the second spring 2223 is connected to the other end of the push block 221. The first spring 2222, the second spring 2223, and the slider 2224 are all sleeved on the outer surface of the rotating rod 2221. The motor 230 is used to drive the rotating rod 2221 to rotate, so that the slider moves within the second operating cavity 222, thereby compressing the first spring 2222 or the second spring 2223. A power supply device 300 is electrically connected to the electronic lock 200.

[0037] It should be noted that when the motor 230 rotates, it drives the rotating rod 2221 to rotate within the slider 2224, thereby causing the slider 2224 to move forward or backward to engage or disengage the clutch mechanism. When the entire lock is in the disengaged state, part of the rotating rod 2221 protrudes above the slider 2224. At this time, the second spring 2223 is compressed, causing the push block 221 to move towards the motor 230. When the motor 230 reverses direction, the slider 2224, under the action of the second spring 2223, is pushed towards the motor 230 by the spiral of the rotating rod 2221. This compresses the first spring 2222, causing the push block 221 to move towards the forward handle assembly, pushing the second operating handle 140 to engage the clutch. At this time, part of the rotating rod 2221 protrudes below the slider 2224. When the motor 230 continues to reverse direction, it will only idle and will not stall. Therefore, the slider 2224 will not continue to move forward, thus protecting the motor 230 and the clutch mechanism. When in gear, the motor 230 rotates forward. The slider 2224, under the action of the first spring 2222, is pushed by the rotating rod 2221 towards the push block 221, compressing the second spring 2223 and causing the push block 221 to move towards the motor 230. The second operating handle 140 then resets and retracts, thus disengaging the gear. At this time, the rotating rod 2221 protrudes above the slider 2224. When the motor 230 continues to rotate forward, it only idles and does not stall, thus preventing the slider 2224 from moving forward and protecting the motor 230 and the clutch mechanism. This prevents the electronic lock mechanism from experiencing situations where it cannot engage or disengage gears.

[0038] Reference Figure 2 The first operating handle 130 and the second operating handle 140 are provided with a handle body 131, a handle seat 132, an adapter block 133, a cover plate 134 and a drive shaft 135. The handle body 131, handle seat 132, adapter block 133 and cover plate 134 are stacked in sequence. The drive shaft 135 passes through the middle of the cover plate 134, adapter block 133 and handle seat 132 and is connected to the handle body 131. A bushing 136 is also connected between the handle seat 132 and the handle body 131. The adapter block 133 is provided with a first through hole 138. The handle seat 132 is provided with a first assembly 1321. The first assembly 1321 is provided with a first pin 1322. The first pin 1322 passes through the first through hole 138 and is connected to the handle seat 132 and the adapter block 133 respectively.

[0039] It should be noted that the handle body 131, handle seat 132, adapter block 133, and cover plate 134 are stacked sequentially and tightly connected by a drive shaft 135. This makes the structure of the first operating handle 130 and the second operating handle 140 more compact, further enhancing the overall strength of the first operating handle 130 and the second operating handle 140, and preventing loosening or deformation of the first operating handle 130 and the second operating handle 140 due to external forces during use. Furthermore, the drive shaft 135 passes through the middle of the cover plate 134, adapter block 133, and handle seat 132, and connects to the handle body 131, ensuring a stable transmission effect for the first operating handle 130 and the second operating handle 140 during operation. This thoughtful design further enhances the stability of the drive shaft 135 and reduces wear caused by prolonged use or improper operation. The first assembly 1321 is provided with a first pin 1322, which passes through the first through hole 138 and is connected to the handle seat 132 and the connecting shaft 133 respectively, so that the handle seat 132 and the adapter block 133 are in a long-term connected state.

[0040] Specifically, when the second operating handle 140 controls the clutch mechanism to engage or disengage, the first operating handle 130 remains locked, and the motor 230 rotates forward or backward to control the movement trajectory of the slider 2224. When the slider 2224 moves away from the motor 230 (i.e., engaging gear), the push block 221 pushes the first pin 1322 away from the motor 230, thus engaging gear; when the slider 2224 moves closer to the motor 230 (i.e., disengaging gear), the first pin 1322 is reset and retracted under the action of the third spring 1323, thus disengaging gear.

[0041] Reference Figure 4 and Figure 5 The rotating rod 2221 is connected to the slider 2224 at one end with a first thread 22211, and the inner surface of the slider 2224 is provided with a second thread 22241. The first thread 22211 and the second thread 22241 are adapted to each other.

[0042] It should be noted that by providing a first thread 22211 at the end of the rotating rod 2221 connected to the slider 2224, and a second thread 22241 on the inner surface of the slider 2224, the motor 230 drives the rotating rod 2221 to rotate within the slider 2224 when rotating, thereby pushing the slider 2224 to move within the first operating cavity 150, thus realizing the engagement or disengagement of the clutch mechanism. Through the precise cooperation of the first thread 22211 and the second thread 22241, precise control of the slider 2224's position is achieved. By rotating the rotating rod 2221, the position of the slider 2224 is adjusted, thereby completing the engagement and disengagement of the clutch mechanism. Those skilled in the art will understand that because the rotating rod 2221 only has the first thread 22211 on the stepped portion, after the first thread 22211 on the stepped portion rotates out of the slider 2224, further rotation of the rotating rod 2221 is merely idle rotation and will not further move the slider 2224.

[0043] Reference Figure 6 and Figure 7 The electronic lock 200 is provided with a first slot 240, and the first panel assembly 110 is provided with a second through hole 121 and an anti-theft mechanism 122. The anti-theft mechanism 122 is connected to the first panel assembly 110 through the second through hole 121. The anti-theft mechanism 122 is provided with a first fixing member 1221, a second fixing member 1222, a third fixing member 1223, a spring 1224, an anti-theft knob 1225, and a lever 1226. One end of the lever 1226 is provided with a third through hole 12261, and both ends of the third fixing member 1223 are provided with fourth through holes 12231. The first fixing member 1221 and the second fixing member 1222 are located on both sides of the second through hole 121. The third fixing member 1223 passes through the second through hole 121. The first fixing member 1221 is provided with a first groove 12211. The second fixing member 1222 is provided with a second groove 12221. The third fixing member 1223 is provided with a third groove 12232. One end of the spring piece 1224 is installed in the first groove 12211. The other end of the spring piece 1224 is installed in the second groove 12221. One end of the lever 1226 is installed in the third groove 12232 and connected to the anti-theft knob 1225. The anti-theft knob 1225 passes through the third through hole 12261 and the fourth through hole 12231. The other end of the lever 1226 passes through the first slot 240.

[0044] It should be noted that by installing the spring 1224 in the first groove 12211 and the second groove 12221, and connecting the lever 1226 with the third groove 12232 and the anti-theft knob 1225, a tight physical connection is formed in the anti-theft mechanism 122. When the anti-theft knob 1225 is rotated, the spring 1224 prevents the anti-theft knob 1225 from automatically rotating and causing the lock mechanism to lock accidentally when the door is closed forcefully. In addition, the modular design of the anti-theft mechanism 122 (such as the detachable connection of the spring 1224 and the lever 1226) makes it more convenient to operate the electronic lock mechanism during maintenance or replacement.

[0045] Furthermore, in this embodiment, the first fixing member 1221, the second fixing member 1222, and the third fixing member 1223 are all cylinders. The spring piece 1224 and the lever piece 1226 are fixed by opening the first groove 12211, the second groove 12221, and the third groove 12232. By adding the spring piece 1224 to the anti-theft knob 1225, the elasticity of the spring piece 1224 is used to prevent the anti-theft knob 1225 from rotating freely.

[0046] Reference Figure 8 The second panel assembly 120 is provided with a first opening 111 and an emergency unlocking device 112. The electronic lock 200 is provided with a first unlocking groove 250. The emergency unlocking device 112 is provided with a first lock cylinder 1121. The first lock cylinder 1121 is embedded in the first unlocking groove 250, and the unlocking port of the first lock cylinder 1121 is aligned with the second opening 12241.

[0047] It should be noted that in special circumstances (such as fire, equipment failure, or other situations requiring immediate evacuation from an enclosed space), the emergency unlocking device 112 allows personnel to unlock the electronic lock without a key or tools. The unlocking port aligns with the second opening 12241, making the unlocking operation more intuitive and convenient, reducing delays caused by complex unlocking procedures in emergency situations. Furthermore, the precise cooperation between the emergency unlocking device 112 and the first lock cylinder 1121 improves the durability and reliability of the electronic lock mechanism, reducing the risk of malfunctions due to prolonged use or harsh environments.

[0048] Furthermore, the emergency unlocking device 112 is also provided with a second assembly 1222, an emergency unlocking cover 1223, and a fourth connector 1224. The fourth connector 1224 is provided with a second opening 12241 and a fifth through hole 12242. The second assembly 1222 is provided with a first screw 12221 and a fourth spring 12222. The emergency unlocking cover 1223 is provided with a fifth connector 12231. The fourth spring 12222 is sleeved on the outer surface of the first screw 12221. One end of the fourth spring 12222 abuts against the end of the first screw 12221. The end of the first screw 12221 away from the end is connected to the emergency unlocking cover 1223 through the fifth connector 12231. The other end of the fourth spring 12222 abuts against the fourth connector 1224. The fifth connector 12231 passes through the fifth through hole 12242.

[0049] It should be noted that the emergency unlocking cover 1223 in this embodiment is a metal cover plate 134, which has high strength, simple structure and easy operation. When performing emergency unlocking, press the lower part of the emergency unlocking cover 1223. Under the action of the first screw 12221 and the fourth spring 12222, the upper part of the emergency unlocking cover 1223 will be lifted. Then, the emergency unlocking cover 1223 is rotated to open. After the emergency unlocking cover 1223 is unlocked, it is rotated back to the initial position and automatically reset under the action of the fourth spring 12222.

[0050] Reference Figure 2 and Figure 9 The handle base 132 is provided with a first shift paddle 1324, a second shift paddle 1325 and a third shift paddle 1326 on its outside, and a torsion spring 137 is also provided between the handle base 132 and the handle body 131.

[0051] It should be noted that by setting the first shift paddle 1324, the second shift paddle 1325 and the third shift paddle 1326 on the outside of the handle base 132, the user can adjust the state of the clutch mechanism by moving the handle body 131. In addition, the multiple shift paddles can also prevent the user from operating them by mistake. Only when the shift paddles of the handle base 132 are in place can the relevant functions of the electronic lock mechanism be realized.

[0052] It should be noted that the torsion spring 137 installed between the handle base 132 and the handle body 131 can automatically reset under the torque of the torsion spring 137 after the handle base 132 is rotated. This allows the torsion spring 137 to drive the handle base 132 back to its initial position automatically when the user completes the operation and releases it, eliminating the need for manual reset. This improves the user experience while ensuring that the electronic lock mechanism maintains stable performance even after prolonged use.

[0053] Reference Figure 10 The second panel assembly 120 is also provided with an alarm unit 113. The alarm unit 113 is provided with a trigger button 1131 and an alarm device 1132. Both the trigger button 1131 and the alarm device are electrically connected to the power supply device 300. The trigger button 1131 abuts against the second panel assembly 120.

[0054] It should be noted that since the trigger button 1131 abuts against the second panel assembly 120, it is not connected to the power supply device 300 at this time. When the door lock is damaged or pried open, the trigger button 1131 pops up and becomes connected to the power supply module. At this time, the alarm device 1132 detects the connection of the trigger button 1131 and thus sounds an alarm. Furthermore, the electrical connection between the alarm unit 113 and the power supply device 300 ensures that it can work normally when needed. This embodiment further improves the security and reliability of the electronic lock mechanism by mutually limiting the trigger button 1131 and the second panel assembly 120.

[0055] Reference Figure 1 The second panel assembly 120 is also provided with a touch panel 114, which is electrically connected to the power supply device 300. The power supply device 300 is also provided with an external power cord, which is electrically connected to the touch panel 114. The first panel assembly 110 is also provided with a battery compartment 115.

[0056] It should be noted that the introduction of the touch panel 114 provides users with a more intuitive and convenient interaction method. Users can input commands, view information, or perform other operations through the touch screen, which is more flexible and modern than traditional buttons or knobs. The touch panel 114 is typically equipped with password input, fingerprint recognition, or other biometric functions, which can significantly improve the security of the lock. Through the touch panel 114, users can set and verify password or fingerprint information, thereby ensuring that only authorized personnel can access the lock. The power supply unit 300 is electrically connected to the touch panel 114 via an external power cord, ensuring that the touch panel 114 can operate continuously and stably when the power supply is stable.
