卷帘门早起源于欧洲，八十年代开始在普及，由于它结构简单，收放自如，既适合安装在空间有限的私家车库、店铺，也适合安装在大跨度、超挑高的工业厂房，因此无论在工作中还是生活中，到处都可以看到卷帘门的身影。

　　Rolling shutter doors originated in Europe and became popular in China in the 1980s. Due to their simple structure and easy retraction, they are suitable for installation in private garages, shopping malls, and shops with limited space, as well as in large-span and super tall industrial plants. Therefore, whether in work or life, rolling shutter doors can be seen everywhere.

　　产品多，品质上就容易出现良莠不齐。有人觉得卷帘门无非是早上开一次晚上关一次，需要什么技术含量，能出什么大问题？好，那么今天我就一次性将这些问题说个清楚。

　　When there are many products, it is easy to have uneven quality. Some people think that rolling shutter doors are nothing more than opening once in the morning and closing once at night. What technical content is required and what major problems can arise? Okay, then today I will clarify these questions all at once.

　　低频启闭的使用场景

　　Low frequency opening and closing usage scenarios

　　对于那些早上开一次晚上关一次的使用场景，如临街商铺，电动、遥控、速度这些就不用过多关注了，需要关注的是防盗性、保温性和开关的流畅性等。

　　For usage scenarios where it is turned on once in the morning and turned off once at night, such as street facing shops, electric, remote control, speed, etc., there is no need to pay too much attention. What needs to be paid attention to are anti-theft, insulation, and smooth switching.

　　高强度

　　high strength

　　既然要防盗，帘板的强度要高，才不于轻易被暴力破坏。市场上常见的S235钢板强度不够，需得S550硬钢钢板，强度高一倍有余，应对一般破坏自然游刃有余。

　　Since we want to prevent theft, the strength of the curtain board should be high first, so as not to be easily damaged by violence. The commonly seen S235 steel plate in the market has insufficient strength and requires S550 hard steel plate, which has more than twice the strength and can handle general damage with ease.

　　帘门帘板采用S550硬钢材质，抗冲击强度高

　　The curtain panel is made of S550 hard steel material, which has high impact strength

　　可锁闭

　　Lockable

　　其次，要能锁闭，特别是一些商铺等民用场所，一旦失窃会造成一定的经济损失。单靠卷帘门自身的结构重力锁闭还不够，额外配备一道机械锁，确保万无一失。

　　Secondly, it should be able to be locked, especially in civilian places such as shops, as theft can cause certain economic losses. Relying solely on the structural gravity locking of the rolling shutter door is not enough. It is best to equip an additional mechanical lock to ensure foolproof safety.

　　卷帘门一体式机械锁，既美观又可保证

　　Roller shutter door integrated mechanical lock, both beautiful and safe

　　保温性

　　Thermal insulation

　　隆冬的寒冷、盛夏的炎热都是对门保温性的考验，市面上的卷帘门多数采用单层钢板，即便是双层，厚度也多在10 mm 以内，内部简单穿插些岩棉条而已。好的卷帘门厚度在 20 mm 左右，内部填充均匀致密的聚氨酯发泡保温材料，保温系数可达3.8 W/m2.K。无论冬天还是夏天都可以省下一笔不菲的暖气空调费用。

　　The cold of winter and the hot of summer are tests of door insulation. Most rolling shutter doors on the market use single-layer steel plates, and even if they are double-layer, the thickness is mostly within 10mm, with simple rock wool strips interspersed inside. A good rolling shutter door has a thickness of about 20mm and is filled with evenly dense polyurethane foam insulation material, with an insulation coefficient of up to 3.8 W/m2. K. Whether in winter or summer, you can save a considerable amount of heating and air conditioning costs.

　　卷帘门帘板厚度约为22mm，内部填充聚氨酯发泡保温材料

　　The thickness of the rolling shutter door curtain panel is about 22mm, and it is filled with polyurethane foam insulation material inside

　　从帘板的形状上看，流线型设计比直线型更合理，因为弧形帘板条卷绕在一起时可以更加自然紧凑，相较于直线型截面帘板，不仅减少了边角位置对帘板表面的摩擦，而且帘卷体积更小，所需的顶部安装空间更小。

　　From the shape of the curtain panel, the streamlined design is more reasonable than the straight type, because the curved curtain Flat noodles can be more natural and compact when rolled together. Compared with the straight section curtain panel, it not only reduces the friction between the edge and corner positions on the surface of the curtain panel, but also reduces the volume of the curtain roll and requires less top installation space.

　　高频启闭的使用场景

　　High frequency opening and closing usage scenarios

　　对于使用相对频繁的电动卷帘门来说，电控系统的限位准确性和保护是重要的两个方面。

　　For electric rolling shutter doors that are used relatively frequently, the accuracy of the electronic control system's limit and safety protection are the two most important aspects.

　　限位准确

　　Accurate limit

　　一樘电动卷帘门，电机应该在门开到什么位置的时候停，不停会怎样？门关到什么位置停，不停又会怎样？

　　When should the motor of an electric rolling shutter door stop when the door is opened, and what happens if it doesn't stop? Where does the door stop and what happens if it doesn't stop?

　　从上图可知，电动卷帘门是在电机带动下将帘板卷绕在门轴上，如果门开到位置，电机没有及时停住，就会将帘板从门框中强制甩出，继而发生坠落伤人危险。

　　From the above figure, it can be seen that the electric rolling shutter door is driven by a motor to wrap the curtain plate around the door shaft. If the door is opened to the highest position and the motor does not stop in time, the curtain plate will be forcibly thrown out of the door frame, which may cause a risk of falling and injuring people.

　　如果门关到位置（地面），电机没有立即停住，而是继续带动帘板向下，帘板则会逐级向下挤压，导致门板变形，久而久之将无法正常关门。如下图这樘门。

　　If the door is closed to the lowest position (on the ground), the motor does not immediately stop, but continues to drive the curtain downwards. The curtain will gradually press downwards, causing the door panel to deform and eventually unable to close properly. The door is shown in the picture below.

　　下限位不准导致卷帘门损坏严重

　　Inaccurate lower limit caused serious damage to the rolling shutter door

　　霍曼卷帘门电控系统配备的数字式编码器，在安装时可自动进行门帘启停位置学习，位置精准，长时间使用后也不会跑偏，确保卷帘门启闭正常。

　　The Hohmann rolling shutter door electrical control system is equipped with a professional digital encoder, which can automatically learn the opening and stopping position of the door curtain during installation. The position is precise and will not deviate after long-term use, ensuring the normal opening and closing of the rolling shutter door.

　　保护

　　safeguard

　　除此之外，卷帘门的性也不容忽视，比如门帘坠落的问题，卷人、压人的问题等等，近年来时常见诸于报端。

　　In addition, the safety of rolling shutter doors cannot be ignored, such as the problem of falling door curtains, rolling and pressing people, etc., which have become common in newspapers in recent years.
