Detailed Description
The following detailed description further illustrates the invention.
As shown in fig. 2 to 5, the utility model provides a technical solution: this novel car C post door frame seal structure, including sealing strip body 2 and buckle 3. The sealing strip body 2 consists of a framework 11, an upper soft edge 12 and a lower soft edge 13; the buckle 3 is composed of a lower body 31, an end cap 32 and an upper body 33.
This use is novel can also further set up to, the section of skeleton 11 is the type of falling L structure, and its upper end fixed connection goes up soft limit 12, and soft limit 13 is down gone up to lower extreme fixed connection, and the intermediate position has the ascending protruding muscle 111 of a length direction, and has one section clearance with the back door for increase the bulk strength of sealing strip skeleton. Through holes 112 for installing the buckles are formed in the positions, close to the rear door, of the side edges, are uniformly distributed in the length direction of the circumference (the through holes 112 are uniformly distributed in the edge extending direction of the door frame) and are used for installing the buckles 3 and fixing the buckles to the rear door 4; the section of the upper soft edge 12 is of an inverted Z-shaped structure, the upper end of the upper soft edge is parallel to the side walls of the rear door and the vehicle body, and the lower end of the upper soft edge is fixed with the framework 11; the section of soft limit is down the type structure of falling T, and wherein end and skeleton are fixed, and right-hand member face 131 upwards extends, surpasss body 33 on the buckle to body 33, automobile body side wall 5 have one section clearance distance on with the buckle, are used for sheltering from the buckle, prevent to expose, play pleasing to the eye effect.
The adverse phenomena of door closing weight, lip protrusion, recess and the like caused by sheet metal manufacturing and poor assembly tolerance of workers are considered. The solution was verified by using CAE analysis: the left end surface 121 tightly attached to the rear door 4 and the right end surface 122 tightly attached to the body side 5 of the vehicle are designed to be in extruded interference fit, so that the sealing strip upper soft edge 12 is tightly attached to the rear door 4 and the body side 5 and does not leave a seam; the left end surface 132 of the lower soft edge 13, which is tightly attached to the rear door 4, is designed to have an extruded interference fit, so that the lower soft edge 13 of the sealing strip is tightly attached to and sealed with the rear door 4.
In order to further enhance the sealing effect of the sealing structure, the novel structure can be further set in such a way that the framework 11 is made of hard material, preferably PP, so that the overall strength of the framework is improved; the upper soft edge and the lower soft edge are made of flexible soft materials, preferably TPV, and the overall sealing effect is improved. The upper soft edge 13, the lower soft edge 12 and the framework 11 are preferably integrally injection-molded by adopting a double-shot injection molding process, so that the overall strength and the sealing effect are improved.
In the novel use process, as the upper body and the lower body of the buckle 3 have the clamping function, a user can firstly install the buckle 3 on the rear door 4 and then install the sealing strip body 2 on the buckle 3; when the sealing strip body 2 is disassembled, the sealing strip body 2 can be disassembled alone without disassembling the sealing strip body 2 together with the buckle 3, and the buckle 3 is still installed on the back door 4. Because the dismouting degree of difficulty between buckle and the sealing strip will be far less than between buckle and the back door panel beating, compare in prior art's buckle and sealing strip convenient labour saving more of dismouting together, and the breakage can often appear when 4 dismouting of buckle 3 and back door panel beating, 3 indirect improvement of buckle economic nature, can repeat with 2 joints of sealing strip body can not appear damaging.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the concept of the present invention, and these improvements and decorations should also be considered as within the protection scope of the present invention.
