The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the utility model are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for completeness and fully convey the scope of the utility model to the skilled person.

As shown in fig. 1-5, a shock absorber upper bracket structure suitable for passenger leather card, the shock absorber includes exoskeleton 1, rubber block 2 and inner frame 3, exoskeleton 1 rigid connection is on the automobile body, a recess 6 has been seted up on exoskeleton 1, recess 6 is the upper end open end, the centre bore that supplies the piston post to pass is seted up to recess 6 lower extreme, the piston post is clearance fit with the centre bore, rubber block 2 sets up in recess 6, the through-hole has been seted up at 2 middle parts of rubber block, 3 joints of inner frame are in the through-hole at 2 middle parts of rubber block, the lateral wall of rubber block 2 is in the same place with the inside wall fixed connection of recess 6, the piston post passes the centre bore and is in the same place with 3 rigid connection of inner frame. A

It should be noted that the outer frame 1 is rigidly connected to the vehicle body, and the inner frame 3 is rigidly connected to the piston rod of the strut damper, and the outer frame is characterized in that the frame 3 moves upwards and achieves the motion impact of the damping link along with certain motion through the elastic deformation of the rubber block 2.

Further, the shock absorber still includes gland 4, and gland 4 sets up on the opening end of recess 6 upper ends, and gland 4 is through riveting rigid fixation on outer skeleton 1, and 4 lower extremes of gland offset with 2 upper ends of block rubber.

It should be noted that, the gland 4 and the cast aluminum framework 1 are rigidly fixed by riveting, and the function of the gland is to ensure that the rubber block 2 does not overflow outwards when compressed.

Further, still include overcoat 5, the lateral wall of overcoat 5 is in close fit with the recess 6 inside wall together, and the lateral wall of block rubber 2 links together with the inside wall of overcoat 5.

Further, the outer side wall of the rubber block 2 and the inner side wall of the outer sleeve 5 are connected together by vulcanization.

It should be noted that the outer sleeve 5 and the rubber are vulcanized, and the function of the outer sleeve is to ensure that the rubber can be fixed on the outer framework 1.
