Description

Omnidistance Stroke Control formula tubulose opens the door, the window machine

Technical field

The utility model relates to the switching mechanism of a kind of door, window, and especially a kind of omnidistance Stroke Control formula tubulose opens the door, the window machine.

Background technology

Existing rolling-gate, garage door, the tubulose of roller shutter window opens the door, the window facility have manually and electronic two kinds of functions, its structure comprises a machine holder and is sleeved on the interior outer tube of spool, position-limit mechanism is housed in the outer tube, rolling door driving mechanism and brake clutch, position-limit mechanism wherein adopts mechanical trip switch or optoelectronic switch and hall signal to control mostly, control with mechanical switch and optoelectronic switch and hall signal has a lot of drawbacks: 1: though use the switch distance that the mechanical trip switch can control gate, if but mechanical switch was run or malfunctioning because of human factor or machinery inertial, the door chance rush to summit above continuously operation causes or below kill, or stuck outage, need artificial recovery just can reuse.2: the control system of using optoelectronic switch and hall signal is to realize the control of opposite house machine range ability by electronic circuit, but optoelectronic switch and hall signal are disturbed by extraneous electronic circuit easily, make transmission data misalignment cause a machine range ability to change, so cause damage a door lifter and an operation door body misalignment, cause accident generation to personal injury and damage property; Optoelectronic switch and hall signal are after door lifter has a power failure in addition, as use open Door by Hand or the moving door body after, when optoelectronic switch and hall signal can not synchronous record open Door by Hand, the mobile data of door and open Door by Hand after when the body position, Qianmen, cause when reusing electric open-door apart from misalignment infringement people and thing.Perhaps the control program of optoelectronic switch and hall signal is set at the original data memory removing in the back that has a power failure, and a machine operation stroke that all will rerun after each power failure is used and opened Door by Hand is remembered, and causes very big inconvenience to the user like this.

Chinese patent CN 90206401.0 " electronics rolling door electronic type position control " discloses a kind of control device that opens the door with potentiometer recognitiion gate body position, but this control device is connected potentiometer with the rotating shaft of door body, and the other installation site of needs sampling potentiometer, it is bigger to take up room, difficulty is installed and influences attractive in appearance, its analog sample and processing are all more loaded down with trivial details in addition, debug cumbersome.

In addition, existing tubulose opens the door, the brake of window machine and arrangement of clutch generally comprise the rear axle brake disc that is connected the electric machine main shaft tail end that opens the door, be arranged at the push-pull electromagnet of a side of rear axle brake disc, it is corresponding with the rear axle brake disc to be fixed with the electromagnetic brake dish on the actuating strut of electromagnet, the bonding surface of electromagnetic brake dish and rear axle brake disc is coarse plane, back-moving spring also is housed between electromagnetic brake dish and the electromagnet, this back-moving spring with the electromagnetic brake dish to rear axle brake disc direction pushing tow, when electromagnet and motor do not power up, the electromagnetic brake dish holds out against on the rear axle brake disc, rely on the frictional force between two cards that electric machine main shaft is locked, electromagnet powers up simultaneously when motor powers up, the elastic force that the actuating strut of electromagnet overcomes back-moving spring retracts the electromagnetic brake dish and breaks away from the rear axle brake disc, remove the locked of electric machine main shaft, electric machine main shaft is rotated and driving switch door (window); What more than use in brake and the arrangement of clutch all is the common electromagnet that powers up the type of keeping, need could keep pulling force to electromagnet one direct power supply to the electromagnetic brake dish, therefore electromagnet relatively takes at consumed power always when machine operation, in addition when have a power failure needing manual sliding door body, at first to remove the locked of electric machine main shaft, though supporting battery can be thrown off electromagnetic brake dish and rear axle brake disc to the electromagnet power supply, but the electric power of battery is very limited, the time that can keep electromagnet is only about 10 seconds, if the user can not finish hand switch door (window) at short notice, battery power exhausts, electric machine main shaft is will be once more locked and can not finish the action of switch door (window), the user can only remove the locked of electric machine main shaft with the manual clutch device again, uses very trouble.
