Detailed Description

The present invention will be further described with reference to the accompanying drawings. An electromotive drive, characterized in that: it includes support 1 and fixes motor 2 on it, the drive wheel 3 of installation on the 2 output shafts of motor, be equipped with outside bellied promotion piece 31 on the drive wheel 3, still include the leading wheel 4 of suit on the output shaft, be provided with guide way 41 on the leading wheel 4, install drive post 6 in the guide way 41, from 5 suits of driving wheel outside leading wheel 4 and drive wheel 3, be provided with drive slot 51 on the hole from driving wheel 5, it moves to the drive slot 51 in from guide way 41 to promote drive post 6 when drive wheel 3 rotates, it rotates to drive from driving wheel 5.

The guide way 41 is the U type setting, promotion piece 31 be provided with two, the symmetric distribution sets up on the outer cylinder of drive wheel 3, promotes the setting on piece 31 protrusion drive wheel 3 outer cylinder.

The pushing block 31 is triangular, and two sides of the pushing block are in smooth transition connection with the outer cylindrical surface of the driving wheel 3.

The driven wheel 5 is further sleeved with a positioning cover 7, the positioning cover 7 is fixedly connected with the support 1, and the driven wheel 5 is positioned in an inner hole of the positioning cover 7 to rotate.

The end face of the driven wheel 5 is provided with a connecting seat 53, a driving shaft 72 is installed on the connecting seat 53, and the driving shaft 72 penetrates through a guide hole in the end face of the positioning cover 7 to be connected with a mechanism to be driven.

The connecting seat 53 is provided with a cross positioning slot 52 therein, correspondingly, a cross positioning block 71 is provided on the cylindrical surface of the driving shaft 72, and the driving shaft 72 is buckled in the cross positioning slot through the positioning block and is in power connection with the driven wheel acting shaft.

The driving groove 51 is a semicircular groove, and the depth of the semicircular groove is equal to or less than the diameter of the driving column 6.

The depth of the guide groove 41 is larger than the diameter of the driving shaft 72.

The driving column 6 is made of magnetic material, and the driving wheel 3 is made of ferromagnetic material.

Wherein, the working process of the electric driver is as follows,

a: when the door is opened, the control system drives the motor to rotate forwards to drive the hinge to be opened, when the hinge reaches the maximum door opening angle, the motor stops rotating, and then the hinge stops rotating after rotating backwards for X seconds.

B: when the door is closed, the control system drives the motor to rotate reversely to drive the hinge to close, when the hinge reaches a minimum door opening angle, the motor stops rotating, and then the hinge stops rotating after rotating forwards for X seconds.

C: when the child lock function is used, the control system drives the motor to rotate reversely for X seconds and then stops rotating.

D: when the child lock function needs to be released, the control system drives the motor to rotate forwards for X seconds and then stops rotating.

The X seconds are set by the control system according to the application environment of the driver, and are preferably between 1 and 3 seconds.

The working principle is as follows: the application of the structure to the oven hinge is taken as an example in the present application for explanation: when the structure is used, the structure is arranged on the main body of the oven hinge, the driving shaft is meshed with a rack arranged in an oven through a gear, and the rack is fixed on a brace of the oven hinge. As shown in fig. 6, when a user needs to electrically open the door, the door opening button is operated, the motor is powered by the control system, the motor rotates forwards, the output shaft of the motor drives the driving wheel 3 to rotate, when the driving wheel rotates, the driving column 6 located in the guide groove is pushed out outwards, one part of the column body of the driving column enters the driving groove, the other part of the column body is located in the guide groove, and therefore the power of the driving wheel is transmitted to the driven wheel through the driving column, and the effect that the motor drives the driven wheel to rotate is achieved. When the driven wheel rotates, the driving shaft 72 transmits power to the gear 73, when the gear 73 rotates, the gear rack 74 meshed with the gear is driven to do linear motion, so that the brace 81 in the oven hinge body 8 drives the hinge arm 82 hinged with the gear to swing, electric door opening is realized, after the door opening is finished, the motor rotates reversely for a period of time (such as 2 seconds), the driving wheel is separated from the driving column to form a state shown in fig. 7, and then the driving column is reset into the guide groove under the action of magnetic force to form a state shown in fig. 8.

And when the user needs the electronic door that closes, only need operate the button of closing the door, control system control motor antiport, drive wheel antiport, realize from the driving wheel antiport can to realized that the electronic door that closes of hinge, in the same way, when electronic door that closes to minimum angle, the motor forward rotates the certain time, makes drive wheel and drive column phase separation, and the drive column resets under the magnetic force effect and gets into in the guide way after that.

When the user need use child to lock the function, control system drive motor reversal X second after stall, at this in-process drive wheel rotation, promote piece 31 and outwards release the drive post all the time, the drive post is not separated with the drive groove to even make the chamber door receive the dragging of external force, also can not open the chamber door, promoted the security of this equipment.

When the child lock function needs to be released, the control system drives the motor to rotate forwards for X seconds and then stops rotating. So that the driving wheel is separated from the driving column, and then the driving column is reset into the guide groove under the action of magnetic force. At this time, the user can open the door manually or electrically. And if the door needs to be opened electrically, the control system executes a door opening program.

Compared with the prior art, the structure realizes the electric opening and closing of the box door in the power-on state, on the contrary, the box door can also realize the manual opening and closing in the power-off state, and has the child lock function without increasing cost, so the structure can be widely popularized and used.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
