顶部结构：快速软帘门(快速卷帘门)的传动机构安装在门洞顶部机箱内，机箱由厚2mm厚镀锌钢板制作而成两端端由厚6mm钢板制作，在端板上设有安装卷轴轴承，驱动电机，平衡系统构件的安装座和安装孔，钢板表面经喷塑处理成客户要求的色彩。卷轴安装于机箱内，由卷筒、轴端、轴承座等组成。卷筒尺寸根据门洞高、宽尺寸经过计算，选择合理尺寸，在这个门上，卷筒直径为219mm。
Top structure: the transmission mechanism of the fast soft shutter door (fast rolling shutter door) is installed in the chassis at the top of the door opening. The chassis is made of 2mm thick galvanized steel plate, and the two ends are made of 6mm thick steel plate. The end plate is equipped with mounting roller bearings, driving motors, mounting seats and mounting holes for balancing system components. The surface of the steel plate is sprayed with plastic to the color required by customers. The reel is installed in the chassis and is composed of drum, shaft end, bearing seat, etc. The drum size is calculated according to the height and width of the door opening, and the reasonable size is selected. On this door, the drum diameter is 219mm.
导槽箱：导槽箱由厚2mm镀锌钢板制作，立于门洞二侧固定于墙面，机箱则置于导槽箱顶部通过螺栓与导槽箱及墙面固定。导槽箱导槽二侧固定有密封毛条，以保证的密封要求，在导槽箱的底部离地约1m高位置，则预留有红外线监测器的安装位置。导槽箱经喷塑处理，与机箱同色，导槽里部的毛刷抵住帘布以限制帘布不会脱离导槽，这样当车子撞到门的时候，门帘会脱离导槽，从而避免门体损坏。

Guide box: the guide box is made of 2mm thick galvanized steel plate, standing on the two sides of the door opening and fixed on the wall. The chassis is placed on the top of the guide box and fixed with the guide box and the wall through bolts. Sealing wool strips are fixed on both sides of the guide groove of the guide groove box to ensure the sealing requirements of the. At the bottom of the guide groove box about 1m above the ground, the installation position of infrared monitor is reserved. The guide slot box is sprayed with plastic and has the same color as the chassis. The brush in the guide slot butts the cord fabric to limit that the cord fabric will not separate from the guide slot. In this way, when the car hits the door, the door curtain will separate from the guide slot, so as to avoid damage to the door body.
帘布：帘布分段制作，每段高度约为700mm左右，各段帘布通过的铝质抗风条联接成一整体帘布，帘布厚1.2mm,具有强度高、抗冲击、不易刺穿等优点。还可选用δ=2mm的透明PVC材料制作帘布或部份选用透明PVC材料制作帘布，以便观察软帘门二侧的情况，在帘布的底部设有铝质底梁，及防撞软袋帘布的顶部通过螺钉和压条固定在卷筒上。
Cord fabric: the cord fabric is made in sections, and the height of each section is about 700mm. The aluminum wind resistant strip of each section of cord fabric is connected into an integral cord fabric. The cord fabric is 1.2mm thick, which has the advantages of high strength, impact resistance and not easy to puncture. Optional δ= 2mm transparent PVC material is used to make cord fabric or part of the cord fabric is made of transparent PVC material to observe the situation on both sides of the soft curtain door. Aluminum bottom beam and anti-collision soft bag are set at the bottom of the cord fabric, and the top of the cord fabric is fixed on the drum through screws and strips.
驱动装置：通过减速马达直接驱动软帘门转轴，根据提升速度的要求选用不同速比的减速器，达到所要求的提升速度，速度可达到80cm/s以上。控制线路采用变频控制，使帘布运行时做到缓起动缓停止，并可使帘布到位自停，及在运行过程中停止运动。
Driving device: the soft curtain door rotating shaft is directly driven by the reduction motor, and the reducer with different speed ratio is selected according to the requirements of lifting speed to achieve the required lifting speed, which can reach more than 80cm / s. The control circuit adopts frequency conversion control to make the cord start and stop slowly during operation, and make the cord stop automatically in place and stop moving during operation.
控制：软帘门设有控制箱，可在控制箱操作“开”“停”“关”并可在控制箱的另一侧墙面设控制按钮操作“开”“停”“关”。可根据需要选配遥控操作和雷达探测或地磁感应自动开关门，在门洞二侧设有红外线监测装置，当门体运动时有障碍物穿越门洞时，帘布运动将停止，或回复到开门状态。
Control: the soft curtain door is equipped with a control box, which can operate "on", "stop" and "off" in the control box, and a control button can be set on the wall on the other side of the control box to operate "on", "stop" and "off". Remote control operation, radar detection or geomagnetic induction automatic door opening and closing can be selected as required. Infrared monitoring devices are set on both sides of the door opening. When an obstacle passes through the door opening when the door body moves, the cord movement will stop or return to the open state.
