Abstract
The utility model belongs to the technical field of spare and accessory parts for automobiles and particularly relates to a rotary damper. The rotary damper comprises a shell body and a rotor, wherein the shell body is provided with a circular-ring-shaped damping chamber along the axial direction; the upper part of the rotor is provided with an end cover; the end cover is connected with sealing steps at the opening of the shell body in a clamping manner; the lower part of the rotor is provided with a circular-ring-shaped rotating core; the rotating core is coaxially mounted in the damping chamber; damping liquid is filled in a gap between the damping chamber and the rotating core; the external wall of the rotating core is provided with damping faces along the axial direction; and the damping faces are provided with damping holes communicated with the internal chamber of the rotating core. The external wall of the rotating core is provided with the damping faces with the damping holes, so that a uniform resisting force is obtained during the rotation of the rotating core due to the fact that the flowing of the damping liquid is baffled, the damping effect is lasting, and the service life is long; and a damping role is played between the internal chamber of the rotating core and damping oil due to the arrangement of damping grooves, and the resisting force is further enabled to be more uniform.
Description
Technical field
The utility model belongs to the auto-parts technical field, relates in particular to a kind of rotation damper.
Background technique
The rotation damper that is used for handle of automobile roof or position like that of prior art, generally be installed on the running shaft of handle, the general structure of this class damper by with cavity housing and the rotor that is arranged in the shell cavity consist of, and be marked with damp liquid in the cavity.The rotor structure of this type of damper has varied, the rotor of a plurality of axial tooths is set such as outer wall, damping is fine when just bringing into use, but after repeatedly using, engender the space between epitrochanterian axial tooth and the damp liquid, cause weakening near the damp liquid tension force of rotor axial tooth, corresponding rotor deattenuation when housing rotates, use a period of time rear damper just to lose its damping function, can only be as common connection hinge, this has just caused using effect very undesirable.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and damping is lasting, the uniform rotation damper of resistance.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:
A kind of rotation damper, comprise housing and rotor, housing is provided with the damping cavity of ring vertically, end cap is arranged at rotor top, the sealed step clamping at end cap and housing opening place, and the rotor bottom is circular rotary core, what rotary core was coaxial is installed in the damping cavity, gap between damping cavity and the rotary core is marked with damp liquid, offers vertically damping area on the described rotary core outer wall, has the damping hole that is communicated with the rotary core inner chamber on the described damping area.
Relative on the outer wall of described rotary core two damping areas that are parallel to each other are set;
Described damping area is perpendicular to the diameter of rotary core;
Position relative with damping area on the internal chamber wall of described rotary core offers damping slot.
The beneficial effects of the utility model are: owing to being provided with damping area with damping hole on the outer wall of rotary core, this with regard to so that in the rotary core rotary course owing to the damp liquid constricted flow has obtained uniform resistance, and damping is lasting, long service life; The inner chamber that is arranged so that rotary core of damping slot also produces damping function with damping oil, further makes resistance more even.

Embodiment
The below is described in detail the embodiment of a kind of rotation damper of the utility model with reference to the accompanying drawings:
According to Fig. 1, Fig. 2 and shown in Figure 3, this rotation damper mainly comprises housing 6 and rotor 1, housing 6 is provided with the damping cavity 3 of ring vertically, end cap 7 is arranged at rotor 1 top, sealed step 2 clampings of end cap 7 and housing 6 openings, and rotor 1 bottom is rotary core 4, rotary core 4 is cylinder-like structure, the bottom of rotary core 4 is end caps 7, offers a circular hole in the middle of the end cap 7, and the relative rotary core 4 in edge stretches out and forms a disc edge.The corner of this edge and rotary core 4 is provided with seal ring 8, in order to seal the slit between damping cavity 3 and the rotary core 4.
Position corresponding with damping area 9 on the internal chamber wall of rotary core 4 offers damping slot 12, and the base plane of damping slot 12 is parallel with damping area 9.
Offer two damping holes 10 on each damping area 9, damping hole 10 is communicated with damping area 9 and damping slot 12.
Be positioned at the position at damping cavity 3 tops on the housing 6, be provided with a sealed step 2 coaxial with axis hole 13, sealed step 2 in order to block seal ring 8, prevent that damping oil from leaking outside.
Waist location on the outer wall of housing 6 is provided with one and encloses the draw-in groove 11 of indent, in order to the axial position of stationary housing 6.Be provided with vertically the positioning block 5 of one section evagination on the outer wall of housing 6, in order to prevent housing 6 rotations.The combination of draw-in groove 11 and location fast 5 can be with the mounting point of being fixed in of shell stability.
Owing to being provided with the damping area 9 with damping hole 10 on the outer wall of rotary core 4, this with regard to so that in rotary core 4 rotary courses owing to the damp liquid constricted flow has obtained uniform resistance, and damping is lasting, long service life; The inner chamber that is arranged so that rotary core 4 of damping slot 12 also produces damping function with damping oil, further makes resistance more even.
