[0025] In order to make the technical means, creative features, achieved purposes and functions implemented by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.
[0026] Refer to Figures 1 to 4 , the figure shows a large-power intelligent lock for a lifting sliding door, including: a lock tongue for protruding from the sliding door, engaging with the door frame to lock the sliding door, or retracting into the sliding door to open the door; a dual drive assembly 40 for driving the lock tongue to achieve a locking action or an unlocking action; an electric drive assembly 20 for electrically driving the dual drive assembly 40; a mechanical drive assembly 30 for manually mechanically driving the dual drive assembly 40; the lower right end of the dual drive assembly 40 is docked with the top of the lock tongue, the middle of the dual drive assembly 40 is hinged to the electric drive assembly 20, and the upper left end of the dual drive assembly 40 is docked with the mechanical drive assembly.
[0027] The present utility model realizes the switching between manual mechanical drive and electric drive and the opening and closing of the sliding door by docking the dual drive assembly 40 with the mechanical drive assembly 30, the electric drive assembly 20 and the lock tongue respectively; it can not only swipe the door card and open and close the door fully automatically with a password, but also open and close the door with a conventional key when the battery runs out. The structure is simple, the operation is convenient, and the safety performance is high.
[0028] The electric drive assembly 20 includes an electric drive motor 21, an electric transmission member, and an electric connection member. The output shaft of the electric drive motor 21 is in transmission connection with the electric transmission member, and the electric transmission member converts the rotational motion of the electric drive motor 21 into a linear motion; the electric connection member is arranged outside the electric transmission member. The electric drive motor 21 is equipped with a speed reducer; the electric transmission member is a ball screw transmission pair 22; the electric connection member is an electric sleeve 23, and the electric sleeve 23 is sleeved on the outer circumference of the nut of the ball screw transmission pair 22. The above electric drive assembly 20 converts the rotational motion of the electric drive motor 21 into a linear motion through the ball screw transmission pair 22, with sensitive transmission and convenient control of the stroke through the movement time.
[0029] The mechanical drive assembly 30 includes a mechanical drive groove 31, a mechanical slider 32, and a mechanical guide rod 33. The top of the mechanical slider 32 extends out of the mechanical drive groove 31, and the bottom of the mechanical slider 32 is fixedly connected to the mechanical guide rod 33. The above-mentioned mechanical drive assembly 30 as a whole is a toggle swing rod structure, with the rotating shaft 42 on the electric drive assembly as the rotating shaft 42 and the rocker link 41 as the seesaw. The two ends of the rocker link 41 move in opposite directions. The structure is simple, the operation is convenient, and it is easy to maintain.
[0030] The double drive assembly 40 includes a rocker link 41, a rotating shaft 42, and a guide post 43. The middle part of the rotating shaft 42 is rotatably inserted horizontally inside the electric sleeve 23. The middle part of the rocker link 41 is hinged to both ends of the rotating shaft 42. The top of the guide post 43 is connected to the right end of the rocker link 41. The electric drive motor 21 drives the electric drive member, and in turn drives the electric sleeve 23 and the guide post 43 to move vertically up and down along the movement direction of the lock tongue. Specifically, the side of the rocker link 41 is L-shaped and looks like a square when viewed from above. A guide cylinder 14 is vertically arranged on the top of the lock tongue, and the guide post 43 moves vertically up and down along the guide cylinder 14 to drive the lock tongue to extend in and out. The rocker link 41 has high material hardness and high stiffness, and the guide post 43 is a steel column with relatively high strength.
[0031] The double drive assembly 40 further includes a drive convex block 44. The drive convex block 44 is vertically and fixedly arranged at the other end of the rocker link 41, and the drive convex block 44 is docked with the front end of the mechanical guide rod 33. Specifically, the longitudinal section of the drive convex block 44 is an isosceles trapezoid with a rounded top transition, and the left side of the bottom end of the mechanical guide rod 33 is docked with the upper right corner of the drive convex block 44.
[0032] Working principle: When the mechanical slider 32 is toggled to the left, the bottom end of the mechanical guide rod 33 pushes down the drive convex block 44 of the rocker link 41. The right end of the rocker link 41 and the guide post 43 move vertically upward together. The guide post 43 disengages from the guide cylinder 14, and the lock tongue retracts to unlock the door.
[0033] The intelligent lock of the sliding door in the above courtyard is set inside. When the door handle 11 is pressed down, the door will be lifted up, and the door panel can slide by horizontal pushing and pulling. In the normal state, when the handle 11 is not rotated, the door will be locked and cannot be pushed. When the guide post 43 is inserted into the guide cylinder 14, it can prevent the handle 11 from rotating, and the sliding door can be anti-locked. The force required to lift the sliding door is relatively large. When a large force needs to be output, the lever principle of the rocker link 41 is used to achieve it, saving length materials and being labor-saving.
[0034] The handle 11 of the high-power intelligent lock is L-shaped, and the overall shape of the high-power intelligent lock is U-shaped; the handle 11 is relatively long, which is convenient for providing a large torque. The outer periphery of the lock tongue side of the handle 11 is covered with a keel frame 12; the cross-section of the keel frame 12 is U-shaped, and the keel frame 12 semi-surrounds the outer periphery of the handle 11 along the length direction; for the U-shaped keel, the black left surface will block the keel to keep it beautiful; the keel frame 12 has high hardness and high stiffness, enhancing the rigidity of the whole product and meeting the large-power requirements of the lifting sliding door. An installation groove 13 is recessed inward in the middle of the lock tongue side of the keel frame 12, and the cross-section of the installation groove 13 is inverted U-shaped; inside the groove of the installation groove 13, some fixing screws can be hidden, which are not visible from the side and keep the aesthetics.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
