One end of the traction rope 7 is fixedly connected with the rope winding wheel 2, and the other end of the traction rope 7 extends out of the shell 203 to be connected with the drawer, and when the traction rope 7 is retracted, the drawer is synchronously pulled back. Of course, a transmission assembly 201 connected with the output gear 1 and a power assembly 202 connected with the transmission assembly 201 are also provided in the housing 203. The transmission assembly 201 and the power assembly 202 may be selected from the well-known and well-established technologies in the prior art, and the present embodiment is not limited thereto.
The electromagnetic assembly 5 is positioned and mounted on the housing 203 by a conventional process such as, but not limited to, interference/adhesive/insert molding.
In addition, it should be noted that, a containing cavity 23 is further concavely arranged around the output shaft 6 at one end of the rope winding wheel 2 facing the output gear 1; a flat spiral spring 8 sleeved on the output shaft 6 is embedded in the accommodating cavity 23; one end of the flat spiral spring 8 is fixedly connected with the output shaft 6, and the other end of the flat spiral spring 8 is fixedly connected with the cavity wall of the accommodating cavity 23. The tightening force of the flat spiral spring 8 is here less than the pushing force required when pushing the drawer.
In an optional embodiment, a spring gasket 9 abutting against the flat spiral spring 8 is further embedded in the accommodating cavity 23, and the spring gasket 9 is also sleeved on the output shaft 6; and the end surface of the spring washer 9 facing away from the volute spring is adapted to abut against the spring 3. A stable support for the spring 3 is achieved by means of the spring washer 9.
In consideration of the use requirement for catching the slight displacement change of the drawer, the embodiment adopts, for example and without limitation, the following structure, specifically, the circumferential outer side wall of the rope winding wheel 2 is further matched and connected with a hall magnetic ring 101; and a Hall element 102 which is suitable for inducing the Hall magnetic ring 101 is also arranged in the shell 203.

The embodiment can capture the drawer closing signal in the drawer opening state through the application of the flat spiral spring 8, and is more favorable for improving the use convenience. The specific process is as follows: when the drawer is in an open state, the flat spiral spring 8 is in a contracted state, so that the traction rope 7 is always kept in a tense state. The tightening force of the flat spiral spring 8 is smaller than the pushing force required when the drawer is pushed, when the drawer is opened, a user lightly touches the drawer, at the moment, under the action of the flat spiral spring 8, the traction rope 7 is tightened and the rope winding wheel 2 rotates, at the moment, the Hall element 102 catches the signal, so that a controller electrically connected with the Hall element 102 makes a command of electrifying the electromagnetic group 5, at the moment, repulsion force is generated between the electromagnetic group 5 and a magnet 4 fixedly connected with the rope winding wheel 2, so that under the action of the repulsion force, the rope winding wheel 2 moves towards the direction of the output gear 1 along the axial direction of the output shaft 6, the spring 3 is compressed, the meshing and the matching of the first crown tooth 21 and the second crown tooth 11 are realized, and the matching of the rope winding wheel 2 and the output gear 1 is also realized. At this time, the power mechanism realizes the rotation of the output gear 1 through the transmission assembly 201 until the rope winding wheel 2 rotates, the traction rope 7 is retracted, and the drawer is pulled back. At above-mentioned in-process, that is to say only need the user to touch the drawer, the signal that takes place to close the drawer, and the drawer of this embodiment can realize closing of electronic mode, has improved the convenient high efficiency nature of use.
It should be noted that, the hall element 102 of the present embodiment is located beside the hall magnetic ring 101, and during the rotation of the rope winding wheel 2, the hall magnetic ring 101 rotates synchronously with the rope winding wheel 2. Specifically, a plurality of pairs of magnetic poles are arranged on the outer side of the hall magnetic ring 101, when the rope winding wheel 2 rotates, corresponding voltage is applied to the hall element 102, and the hall element 102 is compared with the N pole magnetic pole or the S pole magnetic pole of the hall magnetic ring 101 along with the rotation of the rope winding wheel 2. In one embodiment, when the hall element 102 faces the S pole, the hall element 102 outputs a low level signal; when the hall element 102 faces the N-pole magnetic pole, the hall element 102 outputs a high-level signal. The hall element 102 is also electrically connected with an external controller, so that the external controller can receive high and low level signals output by the hall magnetic ring 101 to further determine the rotation condition of the rope winding wheel 2, thereby capturing the slight displacement change of the drawer and obtaining the number of rotation turns of the rope winding wheel 2 by counting the high and low level signals, thereby knowing whether the drawer is closed in place. Of course, the hall magnetic ring 101 and the hall element 102 which work in cooperation can be replaced by a distance measuring mode such as laser distance measuring/ultrasonic distance measuring to capture the slight displacement change of the drawer, so that the judgment of the drawer recovery command is realized.
The specific implementation principle of the drawer retracting mechanism of the embodiment is as follows:
when the drawer is in a state that the drawer does not need to be pulled back, the electromagnetic group 5 is not electrified at the moment, no repulsion exists between the electromagnetic group 5 and the magnet 4 fixedly connected with the rope winding wheel 2 at the moment, the spring 3 can not be stressed by the pressure of the rope winding wheel 2, so that the spring 3 can keep a natural extension state, under the condition, the rope winding wheel 2 is supported by the spring 3, a certain distance is reserved between the pull rod and the output gear 1 along the direction of the output shaft 6, and the first crown tooth 21 of the rope winding wheel 2 and the second crown tooth 11 of the output gear 1 are separated, namely the rope winding wheel 2 and the output gear 1 are separated. In this case, the user can freely open and close the drawer without any influence.
When the drawer needs to be pulled back, the electromagnetic group 5 is electrified, and at the moment, repulsion force is generated between the electromagnetic group 5 and the magnet 4 fixedly connected with the rope winding wheel 2, so that under the action of the repulsion force, the rope winding wheel 2 moves towards the direction of the output gear 1 along the axial direction of the output shaft 6, the spring 3 is compressed, the meshing and matching of the first crown tooth 21 and the second crown tooth 11 are realized, and the matching and matching of the rope winding wheel 2 and the output gear 1 are also realized. At this time, the power mechanism realizes the rotation of the output gear 1 through the transmission assembly 201 until the rope winding wheel 2 rotates, the traction rope 7 is retracted, and the drawer is synchronously pulled back to be closed. At the moment, the Hall magnetic ring 101 is matched with the Hall element 102 along with the rotation of the rope winding wheel 2 to know the rotation number of the rope winding wheel 2, so that whether the drawer is closed in place or not is judged. Of course, whether the drawer is closed in place can be determined by the change of the locked current and the rotating speed, and this embodiment is not limited in any way.
When the drawer is closed, the flat spiral spring 8 is in a relaxed state, and when the drawer is opened, the flat spiral spring 8 is in a contracted state, so that the traction rope 7 is always kept in a tense state. But the tightening force of the spiral spring is always less than the pushing force required to close the drawer. Under the state that the drawer is opened, a user lightly touches the drawer, at the moment, under the action of the flat spiral spring 8, the traction rope 7 is tightened and the rope winding wheel 2 rotates, at the moment, the Hall element 102 captures the signal, so that a controller electrically connected with the Hall element 102 makes a command of electrifying the electromagnetic set 5, at the moment, repulsion force is generated between the electromagnetic set 5 and the magnet 4 fixedly connected with the rope winding wheel 2, so that under the action of the repulsion force, the rope winding wheel 2 moves towards the direction of the output gear 1 along the axial direction of the output shaft 6, the spring 3 is compressed, meshing and matching of the first crown tooth 21 and the second crown tooth 11 are realized, and matching of the rope winding wheel 2 and the output gear 1 is also realized. At this time, the power mechanism realizes the rotation of the output gear 1 through the transmission assembly 201 until the rope winding wheel 2 rotates, the traction rope 7 is retracted, and the drawer is pulled back.
When the drawer is in a closed state, the controller can send an encryption command to electrify the electromagnetic group 5, so that the rope winding wheel 2 is matched with the output gear 1. Due to the existence of the transmission assembly 201 and the power mechanism, if someone wants to forcibly open the drawer, the force needs to be reversely transmitted to the power mechanism so that the motor of the power mechanism is reversely rotated, the force is increased by geometric times, self-locking can be enhanced in a mode of reverse energization of the motor, the force required by forcible opening can reach an unrealizable magnitude, and therefore the difficulty in forcibly opening the drawer is improved, and the use safety of the drawer is improved.
In conclusion, the above manner realizes the intellectualization of the opening and closing of the drawer, and daily manual opening and closing cannot be influenced.
