Description

Technical field:

[0001] The utility model relates to the technical field of electrical equipment, and more specifically to an intelligent constant voltage control and regulation system. Background technology:

[0002] A control system is a management system with its own goals and functions, consisting of a control subject, a control object, and a control medium. A control system means that any interesting or variable quantity in a machine, mechanism, or other device can be maintained and changed in a desired manner. A control system is also implemented to make the controlled object reach a predetermined ideal state. A control system makes the controlled object tend to a certain desired stable state.

[0003] When the air shock absorber is in operation, special control equipment is required to control the air shock absorber. Usually, there are multiple groups of control components on the surface of the control device. It is a very important device. Generally, in order to prevent non-operating personnel from contacting it, a protective box is set on the surface of the control device. However, every time the control component needs to be operated, it is necessary to open the protective box, which wastes a lot of time.

[0004] The Chinese utility model patent "An intelligent constant pressure control system for an air shock absorber" with application number 202220358232.4 records a device in which buttons are arranged in sequence from left to right on the front of the controller. The utility model uses the cooperation of a protective box to protect the controller and prevent outsiders from operating the controller.

The lifting drive structure is connected to the lower end of the lifting glass 7 and drives the lifting glass 7 to move up and down. When it is necessary to operate the touch screen, buttons or knobs, the button 3 on the door 5 can be pressed to lower the lifting glass 7 with one button. At this time, the upper end of the lifting glass 7 is flush with the lower end of the glass frame 6, which is convenient for the operator to work.

[0037] After the operation is completed, the button 3 on the box door 5 is pressed again to lift the lifting glass 7 to the highest position with one button. At this time, the upper end of the lifting glass 7 is closed with the upper end of the glass frame 6, and the inside and outside of the protective box 1 are completely isolated.

[0038] Further preferably, a glass frame 6 is provided in the middle of the box door 5, a sealing gasket is provided on the outside of the glass frame 6, and a lifting glass 7 is embedded in the glass frame 6 in a manner that it can be moved up and down. The sealing gasket can ensure that external rainwater and dust will not enter the interior of the protective box 1 through the gap between the glass frame 6 and the lifting glass 7, thereby ensuring the normal operation of the controller 2.

[0039] Further preferably, the lifting drive structure includes an active arm 9, a driven arm 14, a first cross bar 8 and a second cross bar 10, the active arm 9 and the driven arm 14 are connected in a hinged manner at the middle of the two, the first cross bar 8 and the second cross bar 10 are both provided with a slide groove at the right end, the first cross bar 8 and the second cross bar 10 are parallel to each other and have the same length;

[0041] When the active arm 9 and the driven arm 14 produce relative rotational motion and their upward angle becomes smaller, the angles between the active arm 9 and the driven arm 14 and the ground become larger, and the distance between the first cross bar 8 and the second cross bar 10 becomes larger, so that the lifting glass 7 can be lifted.

[0042] When the active arm 9 and the driven arm 14 generate relative rotational motion and their upward angle increases, the angles between the active arm 9 and the driven arm 14 and the ground decrease simultaneously, and the distance between the first cross bar 8 and the second cross bar 10 decreases simultaneously, so that the lifting glass 7 can be lowered.

[0043] At the same time, during the relative rotation of the active arm 9 and the driven arm 14, the hinge points of the first cross bar 8 and the driven arm 14 and the hinge points of the second cross bar 10 and the active arm 9 remain stationary. At this time, the active pulley slides in the slide groove at the right end of the first cross bar 8, and the driven pulley slides in the slide groove at the right end of the second cross bar 10, ensuring that the first cross bar 8 and the second cross bar 10 always remain parallel.

[0044] Further preferably, a servo motor 13 is fixedly installed on the back of the box door 5, and the output shaft of the servo motor 13 is connected to the gear set 12. The lower end of the active arm 9 is fixedly connected to the arc disk 11, and the outer wheel rim of the arc disk 11 is provided with gear teeth, and the gear teeth are meshingly connected to the gear set 12. The servo motor 13 outputs power, which is transmitted to the arc disk 11 through the gear set 12 and the gear teeth, so that the arc disk 11 rotates. The center of the rotation trajectory is located at the hinge point of the active arm 9 and the second cross bar 10, and the center of the arc disk 11 also coincides with the hinge point.

[0045] The forward and reverse rotation of the servo motor 13 is achieved by controlling the current direction. When the current direction is consistent with the rotation direction of the motor, the servo motor 13 can rotate forward. When the current direction is opposite to the rotation direction of the motor, the servo motor 13 can reverse, thereby achieving the lifting and lowering of the lifting glass 7.

[0046] A button 3 is arranged on the box door 5 , and the button 3 has two contact functions of rising and falling, respectively providing a forward current and a reverse current to the servo motor 13 , so as to realize the forward and reverse rotation of the servo motor 13 .

[0047] Further preferably, a protective shell is connected to the back of the box door 5 by a snap-fit, and the protective shell and the box door 5 form an inner cavity. The servo motor 13, the gear set 12, the arc disk 11, the active arm 9, the driven arm 14, the second cross bar 10 and the first cross bar 8 are located in the inner cavity, which can protect the above structures and is also more beautiful.
