Description
Technical Field
The utility model relates to a bumper shock absorber piston especially relates to a novel split type bumper shock absorber piston, belongs to automobile parts technical field.
Background
With the continuous improvement of the quality requirements of the automobile industry, the performance requirements of a host factory on each part of an automobile are higher and higher, and especially the comfort of user experience is concerned. The automobile shock absorber is used for rapidly attenuating the vibration of a frame and an automobile body and improving the smoothness and the comfort of automobile running. The piston assembly of the shock absorber with a split structure is more and more popular with host factories due to the high damping effect. However, the piston assembly with a split structure is generally composed of two individual bodies with different structures, and is complex in production and high in development cost.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned shortcomings, an object of the present invention is to provide a novel split type damper piston which has simple structure, convenient manufacturing and processing, simplified production complexity and reduced production cost.
Therefore, the utility model adopts the technical proposal that:
The piston split type air conditioner comprises two piston split bodies with the same structure, wherein a central hole is formed in the axial center of each piston split body, a plurality of pits and a plurality of bosses are arranged on the lower end face of each piston split body at intervals, the pits and the bosses are located on the same circumference, the pit and the boss of one piston split body are matched with the boss and the pit of the other piston split body, a plurality of recovery holes are formed in each piston split body, the recovery holes are uniformly distributed around the central hole, a plurality of circulation holes are uniformly distributed on the periphery of the recovery holes, the aperture of the lower end of each circulation hole is larger than that of the upper end of each circulation hole, the aperture of the lower end of each circulation hole of one piston split body is communicated with that of the lower end of the recovery hole of the other piston split body, the sizes of the circulation holes are consistent, an annular groove is formed, the interior of the encapsulation is matched with the annular groove.
As a further improvement of the technical scheme, the concave pit and the convex land of one piston split body are in interference fit with the convex land and the concave pit of the other piston split body.
As a further improvement of the technical scheme, the pits are inverted trapezoidal pits, and the bosses are trapezoidal bosses.
As a further improvement of the technical scheme, the number of the flow holes and the number of the recovery holes are both even.
The utility model has the advantages that:
The utility model discloses simple structure, through adopting the utility model discloses the structure, it is convenient to make processing, reduces development mould expense and time, only need suppress a product when production can, reduced the complexity of production, reduced manufacturing cost, improved production efficiency.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a piston split body, 2 is a central hole, 3 is a pit, 4 is a boss, 5 is a recovery hole, 6 is a circulation hole, and 7 is an encapsulation.
Detailed Description
A novel split shock absorber piston comprises two piston split bodies 1 with the same structure, wherein a central hole 2 is formed in the axial center of each piston split body 1, a plurality of pits 3 and a plurality of bosses 4 are formed in the lower end face of each piston split body 1 at intervals, the pits 3 and the bosses 4 are located on the same circumference, the pits 3 and the bosses 4 of one piston split body 1 are matched with the bosses 3 and the pits 4 of the other piston split body 1, a plurality of recovery holes 5 are formed in each piston split body 1, the recovery holes 5 are uniformly distributed around the central hole 2, a plurality of circulation holes 6 are uniformly distributed on the periphery of each recovery hole 5, the lower end aperture of each circulation hole 6 is larger than the upper end aperture, the lower end aperture of each recovery hole 5 is larger than the upper end aperture, the lower end aperture of each circulation hole 6 of one piston split body 1 is communicated with the lower end aperture of each recovery hole 5 of the other piston split, the outer circumference of the piston split bodies 1 is provided with an annular groove, the outer parts of the two piston split bodies 1 are coated with an encapsulation 7, and the inner parts of the encapsulation 7 are matched with the annular groove.
As a further improvement of the above technical solution, the recess 3 and the boss 4 of one piston split body 1 are in interference fit with the boss 3 and the recess 4 of the other piston split body 1.
As a further improvement of the above technical solution, the dimples 3 are inverted trapezoidal dimples, and the bosses 4 are trapezoidal bosses.
As a further improvement of the above technical solution, the number of the flow holes 6 and the number of the recovery holes 5 are both even.
During assembly, the boss of one piston split corresponds to the pit of the other piston split, so that the two piston splits are combined into a damper piston, the structures of the two piston splits are completely the same, the circulation hole of one piston split corresponds to the restoration hole of the other piston split, the aperture of the circulation hole at the joint is consistent with that of the restoration hole at the joint, the cost of a mold during development is reduced, only one product needs to be pressed during production, and then the assembly is carried out, and the production complexity is reduced.
It is to be emphasized that: the above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
