Abstract

The utility model relates to an automatic lifting push-pull door with an infrared anti-pinch function. The automatic lifting push-pull door comprises a door frame, a fixed door leaf, a movable door leaf, a lifting push-pull component, a multipoint lock driver, a door leaf transmission mechanism and a manual switch. The automatic lifting push-pull door is characterized in that a left frame of the door frame and a corresponding vertical frame of the movable door leaf are respectively provided with an infrared opposite-transmitting sensor; a transmitter and a receiver of each infrared opposite-transmitting sensor are connected with the input port of a controller; and the output port of the controller is connected with the multipoint lock driver and the door leaf transmission mechanism. When the automatic lifting push-pull door is closed, if persons or objects exist among the door leaves and the door frame and an operator can not find the persons or the objects in time, the persons or the objects can be effectively prevented from being damaged by virtue of the infrared opposite-transmitting sensors.

Description

A kind of automatic lifting sliding door with infrared rays pinch resistant functionality

Technical field

The utility model relates to building window, is specially a kind ofly to adopt infrared correlation sensor to prevent the automatic lifting sliding door that human body or article are pressed from both sides.

Background technology

Promote sliding door because of having good airproof performance, sound insulation, at a distance from wind and good heat preservation performance, energy-conserving and environment-protective and adopting are prevented advantage such as the multi-point lock structure that the outside invasion function is strong and are received user's welcome.

Existing automatic lifting sliding door is generally by doorframe, fixedly door leaf, swing leaf, lifting push-and-pull assembly, multi-point lock driver, door leaf transmission mechanism and hand switch constitute.Hand switch generally all is arranged in the control room.When sliding door was closed automatically, if between swing leaf and doorframe, have people or article to exist just, and operating personnel can not in time find, just are easy to damage or make article to damage to human body, and the door body also can be impaired when serious.

The utility model content

The purpose of the utility model is exactly to the existing above-mentioned defective that promotes sliding door automatically a kind of automatic lifting sliding door with infrared rays pinch resistant functionality to be provided.

For realizing above-mentioned purpose; The automatic lifting sliding door that the utility model provides; Its doorframe, fixedly door leaf, swing leaf, lifting push-and-pull assembly, multi-point lock driver are identical with prior art with the door leaf transmission mechanism; Be characterized in, the infrared receiver of infrared correlation sensor is installed on the left frame of doorframe, the RF transmitter of infrared correlation sensor is installed on the swing leaf vertical edge frame corresponding with left frame; The input port of RF transmitter and infrared receiver and controller is joined, and the output port of controller joins with said multi-point lock driver and door leaf transmission mechanism.

The operating principle that the utility model promotes sliding door automatically is, open or close the control signal input controller of swing leaf after, controller output, control multi-point lock driver and the action of door leaf transmission mechanism are realized opening and closing automatically of lifting sliding door.Because of the transmitter and the receiver of controller input and infrared correlation sensor joins, when swing leaf is closed, be positioned in the middle of swing leaf and the doorframe if any people or article; Can block infrared signal, infrared correlation sensor then is defeated by controller with the signal that interrupts, and controller is exported immediately; Stop the operation of door leaf transmission mechanism; Thereby can guarantee to be pressed from both sides human body or article preserve from, sliding door can not be damaged yet, and realizes promoting automatically the pinch resistant functionality of sliding door.

The utility model has the advantages that: when promoting sliding door automatically and closing, exist as people or thing are arranged between swing leaf and doorframe, and operating personnel in time do not find, can avoid human body or article impaired effectively through infrared correlation sensor.

Description of drawings

Fig. 1 promotes the front view of sliding door automatically for the utility model;

Fig. 2 is the installation explosive view that promotes sliding door swing leaf, multi-point lock driver automatically and promote the push-and-pull assembly;

Fig. 3 is Figure 1A-A sectional view;

Fig. 4 is infrared correlation sensor control principle block diagram.

Among the figure: the 1-doorframe, 2-multi-point lock driver, the 3-swing leaf, 4-door leaf transmission mechanism, 5-is door leaf fixedly, and 6-promotes push-and-pull assembly, 7-infrared receiver, 8-RF transmitter, 9-swing leaf vertical edge frame.

The specific embodiment

In conjunction with Fig. 1 and Fig. 2; The utility model promote automatically the doorframe 1 of sliding door, fixedly door leaf 5, swing leaf 3, promote push-and-pull assembly 6, multi-point lock driver 2 is identical with prior art with door leaf transmission mechanism 4; Wherein door leaf transmission mechanism 4 (comprising motor, gear and tooth bar) is installed in the upper hopper chute of swing leaf 3; Multi-point lock driver 2 is installed on the vertical edge frame of swing leaf 3, promotes push-and-pull assembly 6 and is installed in the swing leaf frame.In conjunction with Fig. 3 and Fig. 4; Present embodiment promotes sliding door is installed infrared correlation sensor on the left frame of doorframe 1 infrared receiver 7 automatically; The RF transmitter 8 of infrared correlation sensor is installed on the vertical edge frame 9 of the swing leaf 3 corresponding with doorframe 1 left frame; RF transmitter and infrared receiver form and detect control circuit, join with the input port of programmable logic controller, and the delivery outlet of controller joins with multi-point lock driver and door leaf transmission mechanism.

Below promote the course of action of sliding door automatically for the utility model.

Automatically promote the unlatching of sliding door: import enabling signal promoting under the sliding door closed condition, after controller receives start signal, at first output control multi-point lock driver will promote the sliding-door lock point and open; Door leaf is promoted; Controller is exported control door leaf transmission mechanism more then, and swing leaf is opened, and in opening process, can control the opens wide of door leaf through the control input at any time; When swing leaf was opened to certain width, controller output automatically stopped the action of door leaf transmission mechanism.

Automatically promote closing of sliding door: when swing leaf during in opening; Controller receives shutdown signal, and the door leaf of output control earlier transmission mechanism drives swing leaf and moves to closing direction, if having this moment people or article to exist in the open place; Then can produce blocking-up to the infrared rays of infrared correlation sensor; Output immediately stopped the operation of door leaf transmission mechanism after controller received this signal, and it is motionless that swing leaf promptly is parked in original position, and human body or article are preserved from.After human body or article shifted out infrared correlation sensor surveyed area, the swing leaf operation was restarted in the output of delaying time of controller certain hour; Swing leaf is closed; Output control multi-point lock driver operation then drives and promotes the action of push-and-pull assembly, and swing leaf is fallen.
