Door opener with Hall sensing and braking functions

Technical Field

The utility model belongs to the technical field of the door opener technique and specifically relates to a have door opener of hall response and braking concurrently.

Background

In the prior art, the positioning precision of the door opening machine is not high, the braking capability is poor when the door opening machine needs to be limited, the reaction time is long, and the limiting precision is influenced.

Meanwhile, in the prior art, the Hall element and the magnetic ring are arranged on the output shaft of the door opener for detecting the rotating speed of the door opener, so that the position of the output end is crowded, the normal use of equipment is influenced, and the interference factors are more and the precision is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned technique and providing a have the door operator of hall response and braking concurrently, can promote the convenience of the position precision and the spacing debugging of door operator.

In order to achieve the above purpose, the utility model relates to a door operator with both Hall sensing and braking, which comprises a door operator body, wherein an output shaft of the door operator body extends outwards from the rear end of the door operator body, a hollow support frame is arranged at the rear end of the door operator body, the end part of the output shaft of the door operator body is positioned inside the support frame, a magnetic ring is fixed on the output shaft of the door operator body inside the support frame, a Hall sensing part is fixed on the support frame at the position corresponding to the magnetic ring, a mounting disc is sleeved on the output shaft inside the support frame, a first positioning hole is arranged on the mounting disc, a through second positioning hole is arranged on the output shaft, the first positioning hole on the mounting disc is aligned with the second positioning hole on the output shaft, positioning pins are arranged inside the first positioning hole and the second positioning hole, a friction plate is arranged on the mounting disc far away from one end of the door operator body, the door opener is characterized in that an electromagnet shell is arranged on the support frame far away from one end of the door opener body, an electromagnet is arranged inside the electromagnet shell, a pressure spring is arranged inside the electromagnet shell, a movable friction plate is fixedly connected onto the pressure spring, the movable friction plate can be adsorbed by the electromagnet, the gap between the electromagnet and the fixed friction plate is larger than the thickness of the movable friction plate, and when the movable friction plate is in contact with the fixed friction plate, the pressure spring is still in a compression state.

The positioning pin is an elastic cylindrical pin.

Above-mentioned technical scheme, the output shaft with the door operator body extends in order to ensure the assembly space of magnetic ring and mounting disc to the rear end, in addition through the design of support frame, realizes the assembly to electromagnet housing and electro-magnet. The magnetic ring is arranged corresponding to the Hall sensing component, the Hall sensing component detects the rotating speed of the door opener through the change of the stage number of the sensing magnetic ring, so that the accurate position of opening and closing the door can be known, and the Hall sensing component is connected with a controller of the door opener body. Under the condition of door operator work, the electro-magnet produces suction and adsorbs the activity friction plate on the electro-magnet, there is the clearance this moment between activity friction plate and the fixed friction plate, so the rotation of door operator can not influence, and when needs shut down, the electro-magnet outage, suction disappears, the activity friction plate contacts under the effect of pressure spring with between the fixed friction plate, and can have certain pressure between the two, realize the braking of slowing down to the door operator, and in the machine halt state, contact all the time and exist pressure between activity friction plate and the fixed friction plate, make the location of door operator more accurate, the circumstances such as automatic displacement can not take place. And the locating pin is the elasticity cylindric lock, so when activity friction plate and fixed friction plate contacted, when the resistance was received once to the mounting disc, can carry out the extrusion of certain degree to the elasticity locating pin between mounting disc and the output shaft to realize certain buffering, make equipment operation more stable, safe and reliable.

The utility model discloses the door operator who has hall response and braking concurrently that obtains, it is through reasonable structural design, can effectual realization detect the rotational speed of door operator to ensure the position of switch door, in addition, realize opening the door operator through the design of activity friction plate and fixed friction plate and carry out electromagnetic braking, and have the brake force all the time when door operator's off-state, in order to ensure door operator safety in utilization and reliability.
