电动伸缩门 Electric telescopic door

The motor used in the electric expansion door is a special turbine worm type motor, because of its special transmission principle, high stability, high output torque, low noise, moderate speed.
电动伸缩门主要有伸缩门体、机头、控制器三部分组成。
The electric expansion door mainly consists of three parts: telescopic door body, nose and controller.
1、伸缩门体：伸缩门体是由门体大框、交叉撑、轴（定轴、滑轴）及门体轮等主要部件组成。门体整体为金属结构，按材质又分为不锈钢门体、铝合金门体、压铸铝门体。
1. Telescopic door body: The telescopic door body is composed of large frame, cross brace, shaft (fixed shaft, sliding shaft) and door body wheel. The whole door body is metal structure, which is divided into stainless steel door body, aluminum alloy door body and die-casting aluminum door body according to material quality.
2、机头：由驱动器和电气部分组成，它固定在门体的一端，带动门体伸缩运动，与门体配套使用。
2. Head: It is composed of driver and electric part. It is fixed at one end of the door body to drive the door body to stretch and shrink, and it is used with the door body.

铝合金电动伸缩门主体结构与不锈钢相似，也是利用平行四边形的运动原理，采用标准的铝合金型材直接用模具压制成型，然后通过镀锌管以及交叉连杆连接而成。与传统的不锈钢电动门相比，材质更优，造型更美观，更加耐腐蚀。
The main structure of aluminum alloy electric expansion door is similar to stainless steel. It is also made of standard aluminum alloy profiles directly pressed by mold and then connected by galvanized pipe and cross connecting rod according to the movement principle of parallelogram. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful, and the corrosion resistance is more.
电动伸缩门轨道类型：
Track type of electric telescopic door：
在早期，电动门一般采用三角钢双轨，其施工难度大，路面要求高。随着技术的不断更新，双轨已经被淘汰。
In the early days, electric steel doors were generally constructed with triangular steel double track, which was difficult to construct and required high road surface. With the continuous updating of technology, the two tracks have been eliminated.
市面上主流的轨道模式是单轨和无轨两种。单轨就是在路面用膨胀螺栓固定一根实心方钢或轻轨(轻轨铺设要求较高，但使用寿命较长，采用较多)，以此来进行电动门的导向和抗风；无轨就是在路面铺设隐藏式磁铁，门体在运行过程中根据底部的感应系统来自动导航。
The main orbit modes on the market are monorail and trackless two. Monorail is to fix a solid square steel or light rail with expansion bolt on the road surface (light rail laying requirements are higher, but the service life is longer, using more), so as to guide and resist the wind electric door; Trackless is to lay hidden magnet on the road surface, the door body in operation according to the bottom of the induction system to automatically navigate.
电动伸缩门控制方式：
Control mode of electric telescopic door：
电动平移门常见的控制方式有以下两种：
There are two common ways of controlling electric translational doors:
1、控制手柄，联线控制；
1, control handle, line control;
2、无线遥控，常见的433MHz无线遥控手柄控制；
2, wireless remote control, common 433MHz wireless remote control handle control;
随着信息化发展，外部系统控制方式也越来越多地被采用，如电动门自动放行系统通过嵌入式控制系统或者电脑控制，电脑自动识别车辆号牌，自动开门。
With the development of information technology, more and more external system control methods are used, such as automatic release system of electric door through embedded control system or computer control, computer automatically identify the vehicle number plate, automatic door opening.
电动伸缩门保养方法：
Maintenance method of electric telescopic door：
1、使用方法正确
1. Correct usage
在使用中，动作要尽可能的轻开轻关，不要用力过大过猛；电动伸缩门的开启时，发现有阻碍，应先排除故障。内开内倾窗、折叠电动伸缩门等高档电动伸缩门要严格按说明操作。
In use, the movement should be as light as possible to open the light shutter, do not force too large and too violent; Electric expansion door open, found to be hindered, should first troubleshooting. High grade electric telescopic doors with internal open windows, folding electric telescopic doors and so on shall be strictly operated according to instructions.
