[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1As shown, an electronic lock clutch device includes a lock handle 4, a clutch assembly 3 is fixedly connected to the back of the lock handle 4, an electronic lock assembly 1 is provided on the surface of the clutch assembly 3, and a battery block 2 is provided on the top of the electronic lock assembly 1.

[0025] The electronic lock assembly 1 assists the clutch assembly 3 and the battery pack 2 to be stably installed in a predetermined position, and the clutch assembly 3 assists the connection of the lock handle 4 to jointly play their roles.

[0026] like Figure 2 As shown, the electronic lock assembly 1 includes an installation box 11 , the bottom of the inner wall of the installation box 11 is fixedly connected to the bottom of the clutch assembly 3 , and a driver 13 is fixedly connected to the right side of the bottom of the inner wall of the installation box 11 .

[0027] The installation box 11 assists in the installation of the clutch assembly 3 and the driver 13 , and the driver 13 receives signals to control the function of the drive motor 31 .

[0028] like Figure 2 As shown, an electronic password lock control mechanism 12 is fixedly connected to the top of the inner cavity of the installation box 11, and the electronic password lock control mechanism 12 is located above the driver 13. The top of the electronic password lock control mechanism 12 is movably connected to the outer surface of the battery block 2, and the battery block 2 passes through the top of the installation box 11.

[0029] The battery pack 2 provides power to the electronic password lock control mechanism 12, and when the password of the electronic password lock control mechanism 12 is input and the password is correct, a signal is transmitted to the driver 13. The battery pack 2 is conveniently inserted into the inner wall of the top of the electronic password lock control mechanism 12 from the top of the installation box 11;

[0030] The working principle of the electronic password lock control mechanism 12 is that the core component of the electronic lock is a series of single-chip microcomputers (AT89051), which work together with the peripheral hardware circuits to realize the functions of password setting, storage, recognition and display. When the user enters the password, the single-chip microcomputer will compare the input code with the password stored in the EEPROM. If the passwords match, the single-chip microcomputer will instruct the electromagnetic actuator to unlock. If the password is incorrect, the system allows the user to try to enter it again, up to three times. If the three attempts fail, the single-chip microcomputer will send an alarm to the intelligent monitoring system through the communication line.

[0031] like Figure 3As shown, the clutch assembly 3 includes two slide blocks 310, a key lock mechanism 315 and a fixed ring 33. The outer surface of the key lock mechanism 315 is fixedly connected to the bottom of the inner wall of the installation box 11. The rear axis of the key lock mechanism 315 is provided with a lock shaft 36, and the lock shaft 36 is located at the bottom of the front of the installation box 11. The outer surface of the lock shaft 36 is fixedly connected to gear three 37. The surface of gear three 37 is meshed with gear two 35. The inner wall of gear two 35 is fixedly connected to the handle shaft 34. The outer surface of the handle shaft 34 is rotatably connected to the fixed ring 33. The outer surface of the fixed ring 33 is fixedly connected to the inner wall of the installation box 11, and the fixed ring 33 is located above the key lock mechanism 315. The front of the handle shaft 34 is fixedly connected to the left side of the rear of the lock handle 4.

[0032] By twisting the key lock mechanism 315 with the key, the lock shaft 36 and the gear 3 37 are driven to rotate, thereby engaging and driving the gear 2 35 and the gear 4 38 to rotate, thereby promoting the extension and contraction of the bottom clutch pin 312, achieving the fixed locking and loosening effects of the clutch pin 312. When the key lock mechanism 315 is locked, the rotation of the lock handle 4 will not drive the extension and contraction of the bottom clutch pin 312. When the key lock mechanism 315 is not locked, the rotation of the lock handle 4 can be used to drive the extension and contraction of the bottom clutch pin 312.

[0033] The working principle of the key lock mechanism 315 is composed of a lock branch, a key and a lock. The lock branch is the main component of the key lock. It is a fixed metal piece composed of several grooves, seams, sides and edges. The shape of the key is recorded on it so that the key can be inserted into the lock branch. The key is a tool that can be inserted into the lock branch. It is made of metal plate. Since the shapes and sizes of metal plates vary, only a specific key can match the lock branch to achieve the purpose of unlocking. The lock head is the core component of the key lock. It is a precision mechanical component that can convert the movement of the lock branch and key into the rotation of the lock body, thereby achieving the purpose of unlocking.

[0034] like Figure 4 、 Figure 5 As shown, the bottom of the two slide blocks 310 is fixedly connected to the bottom of the inner wall of the installation box 11, the bottom of the inner wall of the two slide blocks 310 is slidably connected with a slider 311, the top of the two sliders 311 is fixedly connected with a clutch pin 312, the middle of the bottom of the two clutch pins 312 is fixedly connected with a mounting groove 313, and the bottom of the inner wall of the mounting groove 313 is fixedly connected with a rack 314.

[0035] The slider 311, which is slidably connected to the inner walls of the two slide blocks 310, serves to limit the forward and backward movement of the upper and lower clutch pin shafts 312. The mounting grooves 313 provided at the bottoms of the two clutch pin shafts 312 assist in the installation of the rack 314, thereby enabling the engagement of the gear 1 32 and the gear 4 38 to promote the extension and retraction of the upper and lower clutch pin shafts 312. The structure is simple and easy to operate.

[0036] like Figure 3 、 Figure 5 As shown, a drive motor 31 is arranged between the two slide blocks 310, the bottom of the drive motor 31 is fixedly connected to the bottom of the inner wall of the installation box 11, and the output end of the drive motor 31 is fixedly connected to a gear 1 32, and the surface of the gear 1 32 is engaged with the surface of the rack 314 located at the top position.

[0037] The driving motor 31 provides power to drive the rotation of the gear 1 32, thereby promoting the engagement of the rack 314 in the top clutch pin 312, driving the extension and retraction of the clutch pin 312, and realizing the function of individually controlling the clutch of the top clutch pin 312.

[0038] like Figure 5 As shown, the top surface of gear two 35 is engaged with gear four 38, and the bottom of gear four 38 is fixedly connected to a fixed shaft 39. The bottom of the fixed shaft 39 is fixedly connected to the bottom of the inner wall of the mounting box 11, and the fixed shaft 39 is located below the bottom position slide block 310.

[0039] By fixing the shaft 39 and stably connecting it to the bottom of the inner wall of the mounting box 11, the position of the gear 4 38 is fixed, providing stable rotation, thereby engaging with the bottom rack 314 and promoting the clutch and extension of the bottom clutch pin 312.

[0040] The working principle of the present invention is as follows: by twisting and rotating the key lock mechanism 315 through the key, the lock shaft 36 and the gear three 37 are driven to rotate, thereby engaging and driving the rotation of the gear two 35 and the gear four 38, thereby promoting the extension and contraction of the bottom clutch pin 312, and realizing the fixed locking and loosening of the clutch pin 312. When the key lock mechanism 315 is locked, the rotation of the lock handle 4 will not drive the extension and contraction of the bottom clutch pin 312. When the key lock mechanism 315 is not locked, the rotation of the lock handle 4 can be used to drive the extension and contraction of the bottom clutch pin 312. When only the top clutch pin 312 is used, the bottom clutch pin 312 is not locked. The clutch pin 312 at the bottom is in a loose state, and the rotation of the lock handle 4 can be used to arbitrarily drive the opening, closing and extension of the bottom clutch pin 312. At the same time, only the battery block 2 is used to provide power for the electronic password lock control mechanism 12. The password of the electronic password lock control mechanism 12 is input. If the password is correct, a signal is transmitted to the driver 13, thereby controlling the drive motor 31 to provide power, driving the rotation of gear 1 32, thereby promoting the extension and contraction of the top clutch pin 312, realizing separate control and dual control, solving the problems of locking the door when not at home for a long time and using one of the clutch controls alone when often at home, providing convenient selectivity.
