The working principle of the clutch mechanism 7 is as follows: when the pressure sensor 6 detects a hand pressing force acting on the handle, a pressure signal is sent to the motor controller, after the motor controller receives the pressure signal, the motor 73 is controlled to rotate, an output shaft of the motor 73 drives a rotating end of the linear motion output assembly 75 to rotate, the linear motion output assembly 75 converts the rotation of the rotating end into linear motion of the linear motion end, the linear motion end serves as a clutch end 72 and moves from a position initially in limit fit with the handle linkage 3 to a position out of limit fit, at the moment, the handle 1 can be unlocked, after the handle 1 is reset to a locking position, the motor controller controls the motor 73 to rotate reversely, the linear motion end is driven to reset to a position in limit fit with the handle linkage 3, and the handle 1 cannot be unlocked.

As shown in fig. 6 to 9, further, the present embodiment provides a specific linear motion output assembly 75, which includes a clutch rotation shaft 751, a coil spring 753, and a clutch actuator 752; the clutch rotating shaft 751 is in transmission connection with an output shaft of the motor 73, a push rod 7511 is radially arranged on the periphery of the clutch rotating shaft 751, and the clutch rotating shaft 751 is a rotating end; the spiral spring 753 is sleeved on the clutch rotating shaft 751, and the push rod 7511 is inserted into a spiral gap of the spiral spring 753; the clutch rotating shaft 751 penetrates through the clutch executing part 752, the clutch rotating shaft 751 rotates relative to the clutch executing part 752, a guide structure 7521 used for circumferential limiting and guiding along a straight line is arranged on the clutch executing part 752, the clutch executing part 752 is in straight-line guide fit with the shell 71 through the guide structure 7521, the clutch executing part 752 only can move along the straight line and cannot rotate, and serves as a straight-line movement end, and one end of the clutch executing part 752 is a clutch end 72; both ends of the coil spring 73 are fixed to the clutch actuator 752, and the coil spring 73 and the clutch actuator 752 are stationary in the circumferential direction.

The working principle and the working process of the linear motion output assembly 75 are as follows:

the motor 73 drives the clutch rotating shaft 751 to rotate, the push rod 7511 is inserted into a spiral gap of the spiral spring 753 due to the fact that the clutch rotating shaft 751 is axially fixed, the push rod 7511 rotates along with the clutch rotating shaft 751, the push rod 7511 moves in the spiral gap in a guiding mode, the spiral spring 753 and the clutch actuating piece 752 are fixed and limited in the circumferential direction, therefore, the push rod 7511 is matched with the spiral spring 753, and the push rod 7511 rotates to drive the spiral spring 753 and the clutch actuating piece 752 to move linearly. When the pressure sensor 6 detects the hand pressing force, the motor 73 finally drives the clutch actuator 752 to move in the direction that the clutch end 72 of the clutch actuator 752 is disengaged from the handle linkage 3 in a limiting manner; when the handle 1 is released by hand, the motor 73 rotates in the reverse direction after the handle 1 returns to the locking position, and finally the clutch actuator 752 is driven to return to the limit matching position.

Of course, the linear motion output assembly 75 may also be in other structural forms, in this embodiment, the linear motion output assembly 75 may be in a screw rod matching structure, specifically, the linear motion output assembly 75 includes a screw rod and a screw sleeve, the screw rod is in matching socket joint with the screw sleeve, the screw rod serves as a rotating end, the screw sleeve serves as a linear motion end, the screw rod is in transmission connection with the motor 73, and the screw sleeve is circumferentially limited and can only move linearly. Therefore, the motor 73 drives the screw rod to rotate, and the screw rod and the screw sleeve are connected through the thread groove, the screw sleeve is circumferentially limited, so that the screw rod drives the screw sleeve to move along a straight line, and the clutch end of the screw sleeve is in clutch limit fit with the handle linkage piece 3.

Further, as shown in fig. 6-9, in the present embodiment, the clutch mechanism 7 further includes a transmission assembly 74, and the output shaft of the motor 73 is in transmission connection with the rotating end of the linear motion output assembly 75 through the transmission assembly 74. The output shaft of the motor 73 is in transmission connection with the rotating end of the linear motion output assembly 75 at a certain transmission ratio through the transmission assembly 74, and of course, the transmission assembly 74 is not provided, and the output shaft of the motor 73 is directly connected with the rotating end.

Preferably, in the present embodiment, the driving assembly 74 is a gear set, a synchronous belt driving assembly or a chain driving assembly. Preferably, the gear set is adopted for transmission connection, and has the advantages of compact structure and high transmission precision. The gear set is composed of at least two gears, the specific number is not limited, and the first-stage, second-stage, third-stage and other multi-stage speed reduction is realized through the gear set according to the actual situation.

As shown in fig. 6, 8, 10-11, in this embodiment, the handle device further includes a mechanical clutch mechanism 4, and the mechanical clutch mechanism 4 is used to complete the manual unlocking of the cat-eye prevention function when the motor 73 of the clutch mechanism 7 fails. Specifically, the mechanical clutch mechanism 4 includes a clutch mechanical member 42 and a slide switch 41; the moving direction of the clutch mechanical part 42 and the clutch executing part 752 is parallel, and when the clutch mechanical part 42 drives the clutch executing part 752 to move towards the direction of disengaging the limit fit, the clutch executing part 752 moves towards the side far away from the handle linkage part 3; the slide switch 41 is movably disposed on the housing 71 in a direction parallel to the moving direction of the clutch actuator 42, and the slide switch 41 is connected to the clutch mechanism 42, and the slide switch 41 moves in synchronization with the clutch mechanism 42.

The working principle and the working process of the mechanical clutch mechanism 4 are as follows: when the motor 73 of the clutch mechanism 7 cannot rotate, at this time, as shown in fig. 11, the clutch end 72 of the clutch mechanism 7 and the handle linkage 3 are in a limit-fit state, the handle 1 cannot be unlocked, and at the same time, the clutch mechanical member 42 and the slide switch 41 of the mechanical clutch mechanism 4 are both in the anti-peep hole locking position where the clutch end 72 and the handle linkage 3 are in limit-fit. At this time, the slide switch 41 is moved to the peep hole preventing unlocking position, the slide switch 41 drives the clutch mechanical part 42 to move, the clutch mechanical part 42 drives the clutch actuator 752 to move in the direction of disengaging from the limit engagement, as shown in fig. 10, so that the clutch actuator 752 and the handle linkage part 3 are disengaged from the limit engagement, and the handle 1 can be unlocked. In this process, since the clutch rotation shaft 751 is restricted by the motor 73 from rotating, when the clutch actuator 752 moves in a straight line in a direction away from the handle link 3, the coil spring 753 is compressed by the push rod 7511 to accumulate elastic force.

Further, in the present embodiment, when the clutch mechanical member 42 moves toward the side close to the handle linkage 3, that is, moves in the direction of the limit engagement, the clutch mechanical member 42 and the clutch actuator 752 are disengaged from each other, that is, the clutch mechanical member 42 and the clutch actuator 752 are not fixedly connected but are in contact connection, and only when the clutch mechanical member 42 moves in the direction of the limit engagement, the clutch mechanical member 42 and the clutch actuator 752 are in contact connection, and the clutch actuator 752 is pushed to move in the direction of the limit engagement.

When the slide switch 41 moves from the anti-peep hole unlocking position to the anti-peep hole locking position, the slide switch 41 drives the clutch mechanism 42 to return to the initial position. At this time, since the clutch actuator 752 does not have the pushing action of the clutch mechanism 42 and the coil spring 753 accumulates the elastic force, the clutch actuator 752 is returned to the position in which it is in limit engagement with the handle link 3 by the elastic force of the coil spring 753, and the unlocking operation of the handle 1 is restricted again.

The purpose of the non-fixed connection of the clutch mechanical member 42 and the clutch actuator 752 is to separate the movements of the clutch mechanism 7 and the mechanical clutch mechanism 4, so that the respective cat-eye unlocking and locking functions can be independently achieved.

Of course, in the present embodiment, the clutch mechanism 42 and the clutch actuator 752 may also be fixedly connected, and the clutch mechanism 42 and the clutch actuator 752 act synchronously during the unlocking and locking process of the cat-eye prevention device.

Further, in the present embodiment, the mechanical clutch mechanism 4 further includes a return elastic member 43, and both ends of the return elastic member 43 respectively act on the clutch mechanism 42 and the housing 71 to apply an elastic return force to the clutch mechanism 42, the elastic return force moving toward the side close to the handle link 3. The function of the elastic return element 43 is: when the slide switch 41 moves from the peep-proof locking position to the peep-proof unlocking position, the clutch mechanical part 42 compresses the reset elastic part 43, the reset elastic part 43 accumulates elastic reset force, and after the slide switch 41 is released, the slide switch 41 automatically resets from the peep-proof unlocking position to the peep-proof locking position under the action of the reset elastic force of the reset elastic part 43. The resilient return 43 is preferably a compression spring.

As shown in fig. 1 to 4, the present embodiment provides a specific handle apparatus, wherein the handle 1 is a turning handle 11, and the turning handle 11 is rotatably connected to the indoor panel 2 around a horizontal rotation axis perpendicular to the indoor panel 2 of the door lock. When the turning handle 11 is in the horizontal state, the turning handle 11 is in the initial locking position, and the turning handle 11 is held by the hand to be turned downward for the unlocking action.

In this embodiment, when the handle 1 is the turning handle 11, the handle linkage 3 is the handle turning member 31, the handle turning member 31 is coaxially disposed with the horizontal turning axis of the turning handle 11, and the handle turning member 31 is provided with a limit groove 311 engaging and disengaging with the engaging and disengaging end 72.

As shown in fig. 3, when the turning handle 11 is in the horizontal state, the limit groove 311 faces the clutch end 72 of the clutch mechanism 7, and when the clutch end 72 is inserted into the limit groove 311, the clutch end 72 limits the turning of the handle turning member 31, and thus the turning handle 11.

As shown in fig. 4, when the engagement end 72 is disengaged from the stopper groove 311, the handle turn piece 31 can be rotated, and the handle 1 can be unlocked.

Further, in this embodiment, the clutch mechanism 7 further includes a steering limiting plate 8 connected to the clutch end 72, and the clutch end 72 is in clutching limiting fit with the limiting groove 311 through the steering limiting plate 8. The engaging end 72 drives the steering limiting plate 8 to move linearly, and as shown in fig. 3, when the steering limiting plate 8 is inserted into the limiting groove 311, the steering limiting plate 8 limits the rotation of the handle steering member 31, and thus the rotation of the rotating handle 1.

As shown in fig. 4, when the steering stopper plate 8 is disengaged from the stopper groove 311, the handle steering 31 can be rotated, and the handle 1 can be unlocked.

Of course, the clutch end 72 of the clutch mechanism 7 may be directly configured as a stud, and the stud is engaged with the limit groove 311 for clutch limit.

As shown in fig. 1 and 2, in the present embodiment, the rotating handle 11 includes a handle body 111 and a handle cover 112, and the pressure sensor 6 is provided in the handle body 111 and along a position where a user can touch. The pressure sensor 6 is preferably disposed at a position where the thumb can be pressed in a normal posture in which the hand holds the rotating knob 11. Of course, the pressure sensor 6 may be disposed at other positions of the handle body 111, for example, at a portion gripped by a user who rotates the handle 11, as long as the user can feel the hand pressing force.
