Description
Technical Field
The utility model relates to a car door seals technical field particularly, relates to a gasbag formula seal structure.
Background
The automobile door sealing structure refers to a sealing structure between an automobile door and an automobile body of an automobile, and the sealing structure can isolate the environment in the automobile from the outside, and has the main functions of:
1. prevent dust, rain water and the like from entering the vehicle;
2. the static sealing function is adopted, so that the sealing performance of the whole vehicle is improved, and the noise outside the vehicle cannot enter the vehicle through a gap between a vehicle door and a vehicle body;
3. the dynamic sealing function is that when the automobile runs at high speed, the sealing structure made of rubber can deform to form a gap due to the change of the pressure difference between the inside and the outside of the automobile, which is one of important reasons for the generation of wind noise under the working condition of high-speed running, and the good sealing structure can avoid the phenomenon and realize better dynamic sealing effect;
4. promote the sound quality of closing the door, when closing the door, the sealing strip can play the buffering effect of closing the door and assaulting, and the portability of closing the door can be guaranteed again simultaneously in the direct collision of avoiding between metal and the metal to promote the sound quality of closing the door, build the sense of thickness of closing the door.
Traditional door seal structure mainly contains twice sealing strip, installs respectively in door and car frame, and the sealing strip generally adopts the better rubber material of elasticity, and two sealing strips extrude each other when the door is closed and form better sealed effect, still need the trompil simultaneously on the sealing strip to guarantee the inside and outside pressure balance of sealing strip, make the normal deformation unrestricted of sealing strip. However, the conventional sealing structure as a passive sealing method still has some disadvantages:
1. the existing structure relies on a margin-keeping method to realize dynamic sealing, the method relies on rich experience and accurate size control, deviation between a manufacturing size and a design size is easy to occur in the manufacturing process, matching errors occur, and requirements on the design and the manufacturing process are high.
2. In order to ensure the dynamic sealing effect, the sealing strip margin is required to be larger and better so as to resist deformation caused by pressure change during driving, but the supporting force is too large, the door closing difficulty can occur, and how to balance the two is seriously dependent on experience.
3. The sound quality of the closed car door of the car depends on the vibration and the rebound times when the car door is closed, and the passive sealing can not realize accurate pressure adjustment at the moment of closing the car door to cause overlarge pressure, increase the rebound times and reduce the sound quality of closing the car door.
However, some active sealing structures proposed at present, such as the airbag-type sealing strip, also have some problems that are not solved in the practical application of engineering, and mainly include:
on one hand, the airbag-type sealing strip is taken as an inflatable container, the installation mode of the airbag-type sealing strip on an automobile sheet metal is currently prone to reference the installation mode of the traditional sealing strip, namely the airbag-type sealing strip is installed in a button hole on the automobile body side through a single buckle for fixing, but in order to ensure enough connection strength, the buckle is made of a material different from that of the airbag-type sealing strip, and the buckle and the airbag-type sealing strip are connected by adopting a special process, so that higher requirements are provided for the manufacturing process, and higher cost pressure is caused;
on the other hand, present gasbag formula sealing strip scheme is most inclined to install on the panel beating of automobile body side, because gasbag formula sealing strip needs the motor, air pump and relevant gas/electric pipeline are as auxiliary component, if gasbag formula sealing strip is installed on automobile body side panel beating, because the installation space of present automobile body side panel beating department is very limited, original papers such as motor and air pump often can not install near gasbag formula sealing strip and need install far away position, this just needs longer gas circuit pipeline to carry out the connection of air pump and sealing strip, thereby cause great atmospheric pressure loss, more importantly because the gas circuit length can lead to atmospheric pressure control to produce great control delay, lead to that the many advantages of gasbag formula sealing strip can not full play.
