Detailed Description
In order to facilitate use, the embodiment of the utility model provides the sound-insulation rubber block for the lower cavity of the A column. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment provides a sound-insulating rubber block for a lower cavity of an A column, and refers to FIGS. 1 to 3; the integral structure comprises a framework 1, wherein a rubber groove is formed in the periphery of the framework 1 and is used for filling foaming rubber to form a rubber block 8; the framework 1 is of an integral injection molding structure and is of a symmetrical structure so as to be suitable for the left side and the right side of a vehicle body; and a liquid leakage hole 11 is formed in the middle of the framework 1, so that electrophoresis liquid can flow conveniently. Meanwhile, when the water enters the A column, the water can be effectively guided into the doorsill, and the water is prevented from entering a cab.
The foaming adhesive is made of EVA material with high foaming ratio; and embedding the foaming glue into the framework and the periphery of the leakage hole to form a whole in a secondary injection molding mode. The thickness and the width of the glass tube can reach more than 5 mm.
One side of skeleton 1 self is provided with fixed buckle (2 and 3 in the picture), still divides in the both sides of fixed buckle to be provided with at least two sets of support columns, and every group support column includes support column (6 or 4 in the picture) and lower support column (5 or 7 in the picture), goes up support column and lower support column and establishes in the vertical upper and lower branch of skeleton 1, and crisscross each other on horizontal.
The fixed buckle comprises a square buckle and a round buckle so as to realize the mistake-proofing design. The size of square buckle is 8mm, and thickness is 1.8mm, and the diameter of circular buckle is 6mm, and thickness is 1.5 mm. During the installation, at first handheld gluey piece 8 one end makes its fixed buckle correspond with the panel beating installation, then slightly pushes away gluey piece 8 for the buckle gets into the mounting hole, and barb through fixed buckle is together fixed with the panel beating.
Referring to fig. 3-4, when the framework is assembled with the sheet metal part of the vehicle body, the support pillar is in interference fit with the sheet metal, and the interference magnitude is 1.0 mm. The rubber block 8 is firmly fixed on the sheet metal, and the rubber block is easily installed because the contact surface of the supporting column is small (the area of the contact surface can be designed to be 1mm by 2mm) and the insertion force of the rubber block is only 50N.
With continued reference to fig. 1 to 2, the framework 1 is further provided with two diagonal tension columns (9 or 10 in the drawings), the two diagonal tension columns are arranged in the longitudinal direction, the diagonal tension columns are arranged in an inclined manner, and the inclined surfaces are opposite to the metal plates;
the diagonal draw column is positioned on one side, far away from the fixed buckle, of the connection path of the rubber block and the sheet metal. The glue block 8 on one side of the diagonal tension column is provided with a sharp corner area.
Referring to fig. 5, when assembling, a gap (about 0.5 mm) is formed between the diagonal draw column and the sheet metal; when 8 high temperature foaming of gluey piece, when the downward sloping under the promotion of expanding force, glue 8 oblique pull post and panel beating short time contact together, hold gluey piece 8, prevent to glue 8 further downward sloping of piece, can effectively solve like this and glue 8 and have declined too much, lead to gluing 8 and the peripheral panel beating clearance in cross-section problem that increases, and then solve gluey 8 foaming sealing bad problem.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
