Abstract
The invention relates to an automobile seat delayed shock absorber. The automobile seat delayed shock absorber comprises an upper base plate and two lower groove blocks. Two cavity springs are arranged between the base plate and the groove blocks. Each cavity spring is provided with an upper cover and a lower cover which are buckled to each other. A spring is arranged in a cavity formed by each upper cover and the corresponding lower cover. The upper ends of the upper covers are movably connected with the base plate. The lower ends of the lower covers are movably connected with the groove blocks. The upper covers or the lower covers are provided with air holes. Each air hole is provided with a small-end-up wedged hole. The lower portions of the wedged holes are sealed, so that hole cavities are formed. Polyhedral-structure plugging blocks are arranged in the hole cavities. The plugging blocks in the wedged holes can be driven by airflow to not totally plug the wedged holes under the condition that the air release speed is too high, and therefore the air release speed can be inhibited and vibration frequency can be further controlled and interfered with. When the base plate inclines to one cavity spring, the corresponding spring is compressed, the spring on the other side can generate a certain back-to-direction force through the drawing force of the spring, and therefore the inclination degree of the base plate can be reduced.

Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As depicted in figs. 1 and 2, a kind of automotive seat time delay shock-absorbing, comprise: the seat board 1 of top and two geosynclinal blocks 2 of below, two cavity springs 3 are provided with between seat board 1 and geosynclinal block 2, each cavity spring 3 is provided with the upper cover 4 and lower cover 5 buckled mutually, spring 6 is provided with in the cavity that upper cover 4 and lower cover 5 are formed jointly, the movable upper end connecting base plate 1 of upper cover 4, lower cover 5 lower end is flexibly connected geosynclinal block 2, upper cover 4 or lower cover 5 establish pore, it is little that pore is provided with top, the wedged hole 10 that bottom is large, wedged hole 10 bottom is sealed formation vestibule by dictyosome 11, polyhedral structure sprue 12 is provided with in vestibule.
The gap input and output gas that cavity spring 3 needs from upper cover 4 and lower cover 5 owing to letting slip Cheng Zhongjun at contractive pressure and bullet, input and output gas needs the regular hour, like this due to the air pressure reason of inside cavity, the oscillation frequency of cavity spring 3 is just only that its contained spring 6 character determines, but determined by air pressure and spring 6 character two aspect, such cavity spring 3 can be coupled out a unfixed frequency again with the spring 6 be connected with lower cock cap below it, and slow down oscillation frequency, resonance can not be caused also can not to cause a long-term uncomfortable oscillation frequency to human body;
Semiglobe can cushion the power from seat surface thereof direction, ensure the radial rotating flexibility ratio that cavity spring 3 is certain, under sliding plug cylinder, free end is limited in hemisphere groove 8 simultaneously, geosynclinal block 2 can not be escaped from because Oscillation Amplitude is large, also can be conducive to the tilt rotation of shock-absorbing entirety, ensure seat board 1 flexibility ratio of automobile seat;
Sprue 12 in wedged hole 10 can be driven by air-flow and incompletely block wedged hole 10 under the condition of venting excessive velocities, suppresses venting speed, controls further and intervene oscillation frequency;
Cavity spring 3 direction is tilted at seat board 1, namely the spring 6 of its correspondence is compressed, namely the spring 6 of opposite side can produce certain Hui Xiangli by its spring 6 tensile force, the inclined degree of seat board 1 is reduced, mutually neutralize counteracting because of the compression of two springs 6 and elongation each other, ensure the inclined degree range shorter of seat board 1.
Lower cover 5 free end is semisphere 7 structure, and geosynclinal block 2 is provided with the hemisphere groove 8 with semisphere 7 structure matching, and the be staggered gap of part of the upper cover 4 be buckled together mutually and lower cover 5 regulates by adjustment upper cover 4 or the size of carrying out of lower cover 5.
Upper cover 4 free end is semisphere 7 structure, and seat board 1 bottom surface is provided with the hemisphere groove 8 with semisphere 7 structure matching.
Geosynclinal block 2 sliding block joint base plate 13, base plate 13 is provided with slide rail 9, and geosynclinal block 2 is provided with the card article mated with slide rail 9, and card article can move in slide rail 9.
Line between slide rail 9 axis with two cavity springs 3 is parallel.Seat board 1 can be guided like this to move towards direction of tilt, ensure the alerting ability of seat.
Spring 6 natural length is less than the length sum of upper cover 4 and lower cover 5, and spring 6 natural length is less than the length sum of upper cover 4 and lower cover 5, the disengaging that such upper cover 4 and lower cover 5 also can not be threaded off mutually when amplitude is excessive.
It is outside that upper cover 4 is buckled in lower cover 5, and such cavity spring 3 is not easy ponding, ensures the paralysis service life of its inside.
Two cavity springs 3 are arranged in splayed structures slope, and being stretched by a spring 6 between two geosynclinal blocks 2 is connected.Two cavity springs 3 of Eight characters vibrational power flow can when the power of seat board 1 vertical direction changes, seat board 1 can move up and down, the displacement of above-mentioned movement changes, also from the change of cavity spring 3 its length from splayed vibrational power flow two cavity spring 3 angle; Spring 6 between two geosynclinal blocks 2 contributes to ensureing that cavity spring 3 can not be toppled over completely, can provide the restoring force that splayed angle changes all the time, make the displacement of seat above-below direction provide elastic buffer.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine technical scope according to right.
