Abstract

The utility model relates to an electrical machine which is used for a rolling shutter door, a rolling shutter window, and other facilities. The electrical machine is mainly composed of a gear case, a motor, a steel pipe, a control system, and an electrical machine tail seat. The electrical machine is characterized in that the electrical machine includes a position sensor which monitors the relative positions of the electrical machine tail seat and a door-window rolling drum. The control system transmits a closing order based on an obstacle signal provided by the position sensor, and records the present stop position as a closing position limit. The inside of the electrical machine is provided with a sensor which monitors the rotation speed change of the motor, and a rotation speed change signal acquired by the sensor is transmitted to the control system. The control system makes a logic judgment, and then transmits an opening order, and records the present stop position as an opening position limit. After the installation of the electrical machine, the door, and the window, the electrical machine can automatically records the opening and closing positions of the door and the window, and the secondary setting is not required, so the operation is more convenient.

Description

A kind of spacing motor can be set automatically

Technical field

The utility model relates to a kind of motor, is applied to for example facility such as roll-type window or door.

Background technology

Institute is common in daily life for electronic garage rolling screen door, facilities such as electric rolling window, and people can open door and window through manual or remote control, brings many convenience to people's life.But the installation for these facilities is discussed; Under a lot of complicated situations; For example be installed in than under the condition with higher at door and window; Can't regulate electric machine spacing simultaneously and can observe the run location of door and window again, perhaps the position to the open and close of door and window is not hold very clear and definite, causes serious time and the waste on the manpower.

Summary of the invention

The utility model provides a kind of spacing motor of automatically setting of innovation to the deficiency of above-mentioned prior art, through after motor and door and window install, writes down opening of doors and windows automatically and closes the position, back, need not afterwards to set again, operates more convenient.

The utility model solves the technical scheme that its technical problem adopted:

A kind of spacing motor can be set automatically; Mainly constitute by gear box, motor, steel pipe, control system and motor tailstock; It is characterized in that said motor comprises the position transducer of a monitoring motor tailstock and door and window reel relative position; The obstacle signal that control system provides according to this position transducer sends close command, and writes down current institute off-position and be changed to closed spacing; Said motor internal is provided with the transducer that monitoring motor rotor speed changes, and the rotation speed change signal that this transducer obtains is sent to control system, and control system is sent open command after making logic determines, and write down current institute off-position be changed to open spacing.

Described position transducer is a sensitive switch.

Described position transducer is a Hall element.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further description.

Like Fig. 1-shown in Figure 3; But this programme motor is to utilize the cognitive disorders motor to improve to form; After whole door and window all installs, when letting motor promote door and window, collide through the barrier and door and window case or other anticipation setting barriers that arrange in advance on the fine strain of millet at the bottom of the door and window sheet; Motor load strengthens suddenly like this; The motor rotor rotating speed is also at once corresponding slack-off suddenly, can judge motor lifting door and window through the unexpected variation of similar means mensuration motor rotor rotating speeds such as for example Hall element and reach upper limit position, and write down current location; And the position that will upwards will promote later at every turn than the good position of firm record slightly downwards, and the barrier of being arranged before avoiding bumps against after each rising.

But also the function that is hampered downwards of utilizing the cognitive disorders motor in the process that descends.In the downward running of door and window sheet, because the effect of door and window sheet own wt, the relation between reel and the tailstock is initial home position for each parts towards gravity direction are in contact with one another; When fine strain of millet at the bottom of the door and window sheet touches ground or end rail, the door and window sheet will stop to move downward, thereby reel also stops the rotation in succession; The still operation downwards of motor this moment is so originally because action of gravity contacts with each other the parts of applying owing to there is the gap, under the drive of motor; No longer fit to produce separate, before being separated to the maximal clearance, motor is through the element in this gap of monitoring of arranging in advance; Like sensitive switch; Hall element or other sensing equipments are discerned the generation in this gap, thereby come the decision gate window to reach closing state, will write down the present position of stopping of motor simultaneously.

Like this if opening of doors and windows with closed once after, the spacing of motor just can be accomplished setting automatically.

Claims

1. one kind can be provided with spacing motor automatically; Mainly constitute by gear box, motor, steel pipe, control system and motor tailstock; It is characterized in that said motor comprises the position transducer of a monitoring motor tailstock and door and window reel relative position; The obstacle signal that control system provides according to this position transducer sends close command, and writes down current institute off-position and be changed to closed spacing; Said motor internal is provided with the transducer that monitoring motor rotor speed changes, and the rotation speed change signal that this transducer obtains is sent to control system, and control system is sent open command after making logic determines, and write down current institute off-position be changed to open spacing.

2. according to claim 1 spacing motor can be set automatically, it is characterized in that described position transducer is a sensitive switch.

3. according to claim 1 spacing motor can be set automatically, it is characterized in that described position transducer is a Hall element.
