Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. The step numbers in the following embodiments are provided only for convenience of illustration, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.
In the related art, some automobiles are equipped with electric suction doors, which is a safe and humanized configuration, and the automobile equipped with the electric suction door can automatically suck the electric suction door until the electric suction door is completely closed under the condition that the doors of the automobile are not closed. However, in the actual application process, part of passengers are not aware of the function or do not know the function at all, the force is too strong when the door is closed, and huge sound is generated or even the door is damaged. In summary, the problems of the related art need to be solved.
In view of this, the embodiment of the present application provides a control method for an electric suction door, which can effectively perform reasonable braking on a closing action of the electric suction door, and reduce a closing speed of the electric suction door, thereby reducing a force and noise of collision between a door body and a door frame, and effectively prolonging a service life of the electric suction door; and can stop the braking work after playing certain braking action, the closing speed of the electric suction door is reduced this moment, and because the existence of the electric suction device, the door body still can be closed automatically, it is safe in utilization, convenient.
Specifically, the electric suction door in the embodiment of the present application includes an electromagnetic braking device and an electric suction device, wherein the electric suction device is a conventional component for automatically closing the electric suction door; the electromagnetic braking device is used for braking the electric suction door to close the door. Referring to fig. 1, in some embodiments, an electromagnetic brake device may be provided on a rotating shaft of the electric door to perform braking by restricting rotation of the rotating shaft. Specifically, the electromagnetic braking device may include an electromagnet 1, an armature 2, and a brake pad 3; the pivot sets up on stationary plane 4, and when electromagnetic braking device during operation, 1 circular telegrams of electromagnet makes armature 2 promote brake block 3 and stationary plane 4 contact, reaches the damped effect for pivot and stationary plane 4 have certain friction, thereby carry out the braking that the electricity was inhaled the door and was closed the door. In addition, in the embodiment of the application, the friction force between the brake pad 3 and the fixed surface 4 can be controlled by controlling the input power supply of the electromagnetic braking device, so that the braking torque can be flexibly changed. It can be understood that the electromagnetic braking device can effectively brake the closing action of the electric suction door during operation, and reduce the closing speed of the electric suction door, so that the collision force and noise of the door body and the door frame are reduced, and the service life of the electric suction door is effectively prolonged.
The control method proposed in the embodiment of the present application is explained and illustrated below with reference to the above description.
Referring to fig. 2, the method mainly comprises the following steps:
in the embodiment of the application, a sensor can be arranged on a door frame of the electric suction door, the sensor is used for detecting the distance between the edge of the electric suction door and the door frame, and then the door closing speed of the electric suction door can be calculated through a plurality of distance data and time interval data measured in a continuous time period. Specifically, the sensor may be any one or more of a magnetic induction sensor, a photoelectric induction sensor, an infrared sensor, or the like. The door closing speed here may be a linear speed or an angular speed of the rotation of the electric door. Of course, the way of measuring the door speed is not limited to the above-mentioned method, and the above-mentioned speed measurement method is only used for illustration.
in the embodiment of the present application, the detected door closing speed is compared with a preset speed threshold, and the preset speed threshold is recorded as a first preset speed threshold, where the first preset speed threshold and the door closing speed have the same format, and may be a linear speed or an angular speed. The first speed threshold value of predetermineeing that sets up is used for judging whether the speed of closing the door is too fast, and when the speed of closing the door was greater than first speed threshold value of predetermineeing, can think that the electric door-sucking's the speed of closing the door is too fast this moment, probably can inhale the door and cause the harm to automobile body or electricity to and produce great noise influence user or other people. On the contrary, when the door closing speed is less than or equal to the first preset speed threshold, the door closing speed of the electric suction door at the moment is considered to be proper and belongs to the normal action category, and the braking treatment is not needed. Here, the size of the first preset speed threshold may be flexibly set and adjusted as needed, and is not fixed to a specific value. When the door closing speed is determined to be greater than a first preset speed threshold value, the electromagnetic braking device is started to brake the closing of the electric suction door, so that the collision force when the door body is closed is reduced.
In some embodiments, the electromagnetic braking device in the present application may comprise a controller, which may be a PID controller, for example, for controlling the torque generated during braking. Specifically, it is understood that the larger the closing speed is, the larger the torque required for braking is, and thus the magnitude of the braking torque can be set to be positively correlated with the closing speed. In the braking process, according to the door closing speed, a proper output torque is output through the controller, and then the electromagnetic braking device is enabled to brake the electric suction door according to the output torque.
Furthermore, since the electric suction door is slowly reduced in speed when being pushed to close by a user, there may be some cases where the initial speed of the electric suction door is fast at the beginning, but the speed to the rear is normal without braking. In order to determine the appropriate brake actuation position. In the embodiment of the application, the distance between the edge of the electric suction door and the door frame can be detected. And then comparing the distance with a preset distance threshold, recording the distance threshold as a second preset distance threshold, and when the detected distance is smaller than the second preset distance threshold, determining that the door closing speed of the electric suction door can be detected, so that the judgment accuracy and the control reliability are improved.
and 140, when the distance is smaller than a first preset distance threshold value, closing the electromagnetic braking device, and starting the electric suction device to automatically close the electric suction door.
In the embodiment of the present application, as mentioned above, a sensor may be disposed on the door frame of the electric suction door, and the sensor is used for detecting the distance from the edge of the electric suction door to the door frame. The distance that detects here can be used for judging whether having got into the work area of electric suction device, when getting into work area, can coordinate the work of electric suction device and electromagnetic braking device, closes electromagnetic braking device, starts the electric suction device and makes the electric suction door carry out automatic closure, can effectively make the execution of braking and electric suction two processes keep apart like this, prevents both influences each other, reduces unnecessary energy loss.
It can be understood that, a complete braking process in the embodiment of the present application is specifically: when the distance between the electric suction door and the door frame is found to be smaller than a second preset distance threshold value, the door closing speed of the electric suction door is detected; when the door closing speed is greater than a preset speed threshold value, the electromagnetic braking device is opened to brake, and when the distance between the electric suction door and the door frame is found to be smaller than a first preset distance threshold value, the electromagnetic braking device is closed, and the electric suction device is opened to enable the electric suction door to be automatically closed. The second preset distance threshold is greater than the first preset distance threshold, and the working time of braking can be adjusted by adjusting the distance between the second preset distance and the first preset distance.
In some embodiments, in the braking process, the door closing speed of the electric suction door is already low through the deceleration effect of the electromagnetic braking device, and if the door is braked again, the door may not reach the working distance area of the electric suction device, so that the electric suction door cannot be normally closed. Therefore, another smaller preset speed threshold value can be set in the embodiment of the application, and is recorded as a second preset speed threshold value, when the door closing speed reaches or is smaller than the second preset speed threshold value, the door closing speed at the speed is considered not to damage the vehicle body, the vehicle body can be normally closed, at the moment, the electromagnetic braking device can be related, and the electric suction device is started to automatically close the electric suction door.
