Description
Technical Field
The invention belongs to the technical field of automobiles, and particularly relates to a novel B-pillar noise-proof sealing structure of a vehicle door.
Background
With the rapid development of science and technology, automobiles have greater and greater influence on China common people. The automobile reflects the living state and the living mode of a nation and social progress as a comprehensive body of science, society, design, fashion and trend development.
The improvement of the living standard of people promotes the development of automobiles, and the development of the automobiles can adversely affect the original traditional life style and traditional culture, namely, the automobiles enable the traditional life to be more convenient; the comfort of the family can be extended; the fashionable bag wraps every corner around us, so that the user can more understand to enjoy life after work.
The B-pillar extends from the roof to the underbody between the front and rear seats of the cockpit. The position of the B column of the automobile is the side body of the automobile, which is the most flexible and fragile position, the requirement on the B column is higher in material selection, and the B column generally needs to be made of high-strength boron steel.
The strength of the vehicle B-pillar is of great significance to the life of the vehicle.
With the development of the automobile field, the requirements of consumers on the automobile commodity (such as wind noise and sealing performance) are gradually improved, and the application of the door noise-proof sealing strip to the automobile is increased.
The door sealing strip (auto door rubber seal strip) is mainly used for fixing, dust prevention and sealing of a door. The rubber material is mainly formed by foaming and closely compounding Ethylene Propylene Diene Monomer (EPDM) rubber with good elasticity, compression deformation resistance, aging resistance, ozone resistance and chemical action and wider use temperature range (-40 ℃ to +120 ℃), contains a unique metal clamp and a tongue-shaped buckle, is firm and durable, and is beneficial to installation. The door is mainly applied to door frames of car doors and windows, side windows, front and rear windshields, engine covers and trunk covers, and has the functions of water resistance, dust prevention, sound insulation, temperature insulation, shock absorption, decoration and the like.
The reasonable noise-proof sealing strip structure is beneficial to improving the sealing performance, reducing the wind noise and improving the automobile commodity performance. The existing automobile sealing strip structure basically has the following structures:
1) an automobile sealing strip with a novel framework structure comprises a clamping part and an elastic sealing part, wherein the clamping part is clamped with a sheet metal part of an automobile body, and the elastic sealing part is fixed on one side of the clamping part; the elastic sealing part is internally provided with a cavity, the clamping part is U-shaped, the inner wall of the clamping part is provided with a plurality of clamping feet, a metal framework is embedded in the clamping part along the length direction of the sealing strip, the metal framework comprises a framework positioned in the middle, a left fin and a right fin, the left fin and the right fin are positioned on two sides of the framework and extend leftwards and rightwards respectively, and the length of the left fin is greater than that of the right fin; the bone body is provided with a plurality of first strip-shaped through holes and a plurality of second strip-shaped through holes along the length direction, and the first strip-shaped through holes and the second strip-shaped through holes are alternately arranged; the length of the first strip-shaped through holes is larger than that of the second strip-shaped through holes, and the left end of each first strip-shaped through hole is flush with the left end of each second strip-shaped through hole. The problem that the clamp cannot be applied to the vehicle with a large bending angle of the metal plate of the vehicle body is solved, and a certain clamping force is kept.
2) A novel sealing strip is formed by a first sponge bubble tube in a D shape and a second sponge bubble tube sleeved outside the first sponge bubble tube; the upper side and the lower side of the first sponge bubble tube are respectively provided with a V-shaped groove which is formed by inwards sinking; a filling body is arranged in the first sponge bubble tube, and the shape of the filling body is matched with that of the first sponge bubble tube; the second sponge bubble tube and the V-shaped groove form a cavity, and a plurality of through holes are uniformly distributed on the second sponge bubble tube at the cavity; the noise-reducing sealing strip has good sealing effect and long service life.
3) The automobile door sealing strip comprises a base body and a bubble tube, wherein the bubble tube is connected to one side of the base body, a water retaining sealing lip extends obliquely upwards from the other side of the base body, and a sponge core is arranged inside the bubble tube. The sealing strip is simple in structure and reasonable in design, the sealing performance of the vehicle door is greatly enhanced by arranging the water retaining sealing lip and the sponge core, the sealing strip is more convenient to mount and firmer to mount as the inner and outer lapping edges are arranged, and the sponge core can also play a role in reducing noise.
However, the sealing tape of the above structure has the following problems:
the cost is high: the B-column noise-proof sealing strip is integrated with the European glass guide groove, so that the cost is high.
The door closing comfort is as follows: the addition of the noise-proof sealing strip is helpful for improving the sealing performance, but also can increase the counter force of the car door in the opening and closing process, and causes poor hand feeling of closing the door.
Poor appearance: the upper end of the noise-proof sealing strip is discontinuous, and the appearance consistency is poor.
