Detailed Description
The present invention is further described with reference to the accompanying drawings and examples.
Referring to fig. 1 to 4, the present invention includes a base 19 and a door plate rotatably connected to the base 19.
The door plate comprises a mother door plate 2 and a sub door plate 1 which is arranged in the mother door plate 2 and is rotatably connected with the mother door through a sub door rotating shaft 4.
The mother door panel 2 is fixedly connected with a rocker arm 3, and the rocker arm 3 is in a rotating connection with a base 19 through a rotating shaft 11 and a pressing plate 12. The base 19 is also fixedly provided with a motor 16, and an output shaft of the motor 16 is fixedly connected with a motor connecting rod 8. One end of the motor connecting rod 8 is rotatably connected with a sub-door connecting rod 6 through a connecting rod rotating shaft 10, and the other end of the sub-door connecting rod 6 is rotatably connected with the sub-door panel 1 through a sub-door connecting shaft 5. The motor connecting rod 8 is also rotatably connected with a rocker connecting rod 7 through another connecting rod rotating shaft 22, and the other end of the rocker connecting rod 7 is rotatably connected with a rocker through a rocker rotating shaft 9.
And a tension spring 14 is fixed at the end of the motor connecting rod 8 extending outwards, and the other end of the tension spring 14 is fixedly connected with a base 19.
The base 19 is also fixedly provided with a rear limit collision block 13. A rocker arm tension spring 15 is also fixedly connected between the rocker arm 3 and the bottom plate of the base 19. The rocker arm connecting rod 7 is provided with a limiting protrusion 7.1 which can limit the movement of one end of the sub-door connecting rod 6. The rubber roller 20 is fixed on one side of the sub door panel 1 in the main door panel 2.
The base 19 is also fixedly provided with a driver 17. The pressing plate 12 is fixedly connected with the base 19 through a supporting rod 21.
Referring to fig. 3 to 4, the working conditions of the present invention are briefly described as follows:
when the door core is powered on for the first time, the driver 17 controls the motor 16 to drive the motor connecting rod 8 to rotate, the motor connecting rod 8 is respectively connected with the rocker arm connecting rod 7 and the sub-door connecting rod 6 through the connecting rod rotating shaft 22 and the connecting rod rotating shaft 10, the rocker arm connecting rod 7 pushes the rocker arm 3 to push the main door panel 2 out, and meanwhile, the sub-door connecting rod 6 pushes the sub-door panel 1 out, so that the effect of synchronously pushing the main door and the sub-door is achieved. Then, one end of the sub-door connecting rod 6 is just contacted with the limiting protrusion 7.1 on the rocker arm connecting rod 7, the door panel is limited to extend continuously, and at the moment, the controller records the position information of the motor 16 as the position information of the farthest extending end of the door panel.
And the subsequent motor 16 rotates reversely until the motor connecting rod 8 is driven to impact the rear limit impact block 13, and at the moment, the controller records that the position information of the motor 16 is the position information of the innermost retracted door plate.
The drive 17 then controls the motor 16 during operation to move the door panel between these two positions as close as possible without encountering a limit.
The subsequent door plate moving-out position is controlled by the motor 16, when the door plate moves out, an included angle is formed between the sub-door connecting rod 6 and the motor connecting rod 8 and the center of an output shaft of the motor 16, the included angle and the holding force of the motor 16 enable the door plate to bear the inward thrust of a set force value, and when the thrust is larger than the set force value, the motor 16 and the door plate automatically release to prevent people from being injured by clamping.
If the door plant loses electricity suddenly when the open mode, 14 pulling motor connecting rods 8 of extension spring this moment, the rocking arm extension spring 15 pulling rocking arm 3, primary and secondary door plant is heavier relatively, uses the design of dual spring, alleviates the atress burden of every extension spring, improves extension spring life, makes the door plant also can self return in the state of losing electricity, and back spacing hits 13 head and is the rubber material, offsets and assaults when the door plant returns.
The sub-door plate 1 penetrates through the middle part of the mother door plate 2, a larger fan shape is formed when the door plate is opened, and meanwhile, the rubber idler wheels 20 are installed on the sub-door plate 1, so that noise is not generated when the sub-door plate moves, and the shaking condition is reduced when the sub-door plate is shot out.
The utility model discloses by 16 full authority control door mechanism switch door actions of servo motor and the position that targets in place, get rid of complicated mechanical motion structure and the adjustment structure that targets in place, most adjustments are by program control, easy operation is convenient.
The present invention is not limited to the present embodiment, and for those skilled in the art, it is intended that the present invention shall not be limited to the embodiments, but the present invention shall be covered by the appended claims.
