What is a parking station? Introduction to mdash & ampmdash
The function of door detection is to limit the opening degree of the door. On the one hand, it can limit the maximum opening of the door and avoid opening the door too large; On the other hand, it can keep the door open when necessary, for example, when the car is parked on a ramp or most of the wind blows, the door may not close automatically. The door opener we often encounter is a separate pull plug, and some plugs are integrated with the door hinge. Generally speaking, they have the function of limiting the door to be fully open and half open.

Rubber spring type
Working principle: the retainer bracket is fastened to the car body through mounting bolts, and the retainer box is fastened to the car door through two mounting bolts. When the door is opened, the limiter box will move along the limiter arm. Because the structure and height of the limiting arm are different, the elastic rubber block will have different elastic deformation, so people should use different forces to close the door when opening the door. At every limit point, it can limit the door. This structure is the most widely used at present, and there are many specific forms: some limit arms are stamped, some limit boxes use needle rollers, some limit boxes use balls, and some limit boxes use sliders &; Hellip & ampHellip, but the limit principle is similar. The advantages of this structure are simple structure, low cost, small occupied space and no maintenance. The disadvantage is the high demand for sheet metal. If the hinge strength is not enough, the door will sink and it is easy to produce noise. After running for a period of time, the limit torque drops rapidly. Most of the door guards with this structure have two or three gears, the maximum torque is about 35N.m, the length is about 60mm, the maximum opening angle is below 70 degrees, and the torque change after durability test is almost 30%-40%.

torsion spring
Its working principle is: it is integrated with the hinge and is usually installed on the lower hinge. In the process of closing the door, the deformation of the torsion bar will produce different forces to achieve the purpose of limiting. This structure is widely used in the European automobile market and is Edith's patent. The advantages of this structure are low noise, long service life and good limit effect. Disadvantages are large space, complex structure and high maintenance cost. Most limiters with this structure have two or three gears, the maximum opening torque is 45N.m, the maximum closing torque is 50N.m, and the maximum opening angle is about 60-65 degrees. After the endurance test, the torque changes about 15%.
The above is a brief introduction of what a car stopper is by the car editor. What about the car plug? The car editor briefly introduced three aspects for friends, namely, the introduction of car gears and two categories. So how much do the friends basically know after reading the profile of the car editor? I hope that the introduction of the car system can solve the problem for friends, and today's introduction is over!
