Embodiment
Below, by reference to the accompanying drawings, structure of the present utility model and working principle etc. are further described.
Rotation damper of the present utility model is widely used in, on the parts of the body rotation that such as door, lid, handle etc. can connect around it, playing the effect of buffering.The utility model is described for the rotation damper be applied on automobile handrail box, and automobile handrail box comprises body for storing and the lid that is connected on body.
Fig. 1 is the perspective view of rotation damper of the present utility model, and this rotation damper comprises housing 1 and is rotationally connected with the rotor 2 of housing 1.Fig. 2 shows the perspective view of housing 1, and Fig. 3 shows the perspective view of rotor 2.Fig. 4 is the longitudinal sectional view of this rotation damper, it illustrates the internal structure of this rotation damper.
See Fig. 2, Fig. 4, the housing 1 of this rotation damper is generally integral piece, it comprises urceolus 101 and is coaxially arranged at the inner core 102 in urceolus 101, annular bottom plate 103 is provided with between the bottom of urceolus 101 and inner core 102 (being as the criterion with direction shown in scheming), urceolus 101, inner core 102 and annular bottom plate 103 are surrounded by annular housing 104, and annular housing 104 one end is closed by annular bottom plate 103, and the other end is uncovered shape, it such as, built with viscous fluid 4, silicone oil etc.As shown in Figure 2, urceolus 101 arranged outside has along the axially extended anti-convulsion 1011 of housing 1, is fixedly installed on the body of automobile handrail box by housing 1 by anti-convulsion 1011.
See Fig. 3, Fig. 4, the usual part that is also formed in one of rotor 2 of this rotation damper, the joint 201 comprising tubular blade part 203, the intermediate portion 202 be connected with blade part 203 and be connected with intermediate portion 202.
Blade part 203 is inserted in annular housing 104, and when rotor 2 rotates, blade part 203 stirs viscous fluid 4 in annular housing 104, produce shearing force, thus viscous fluid 4 pairs of blade parts 203 form damping force, make rotor 2 slowly rotate, and then lid is made slowly to be opened or close.As shown in Figure 3, blade part 203 circumferentially offers several rectangular indentation 2031 near one end (lower end namely shown in figure) of annular bottom plate 103, this rectangular indentation 2031 is uniformly distributed along blade part 203 circumference, quantity can be four, and its axis along blade part 203 extends, lower end is uncovered shape, and be communicated with outside and the inner side of blade part 203, make, in annular housing 104, more viscous fluid 4 to be housed, when blade part 203 stirs viscous fluid 4, the damping force of viscous fluid 4 pairs of blade parts 203 increases further, and then improve the damping of this rotation damper.
Continue see Fig. 3, Fig. 4, intermediate portion 202 is formed with the first ring connected in star 2023 along this intermediate portion 202 circumference with the joint of blade part 203, can arrange O-ring seals 3 intermediate portion 202 and urceolus 101 to be sealed in this first ring connected in star 2023; Simultaneously, as shown in Figure 4, the top of inner core 102 (being as the criterion with direction shown in scheming) is provided with stepped part 1021, it can be set with O-ring seals 3 inner core 102 and intermediate portion 202 to be sealed, annular housing 104 seals by above two O-ring seals 3, prevents the leakage of viscous fluid 4.The top that intermediate portion 202 is positioned at first ring connected in star 2023 offers the second annular groove 2022 along this intermediate portion 202 circumference; Correspondingly, as shown in Figure 2, the top of urceolus 101 (being as the criterion with direction shown in scheming) inner side is provided with four protuberances 1012 rotated along the second annular groove 2022, to realize being rotationally connected of housing 1 and rotor 2.
As a kind of optimal way, intermediate portion 202 is provided with collar flange 2021 away from one end of blade part 203, the outer diameter D 1 of collar flange 2021 is identical with the outer diameter D 2 of urceolus 101, after rotor 2 is inserted housing 1, collar flange 2021 is covered on the open-mouth end of urceolus 101 just, prevents extraneous dust from entering in housing 1.Further, as shown in Figure 3, Figure 4, this collar flange 2021 simultaneously can as the upper end part of the second annular groove 2022.
See Fig. 1, Fig. 4, joint 201 is two spaced rectangular blocks, the opposing side of two rectangular blocks all offers the axially extended curve bath 2011 along housing 1, this joint 201 can be installed on the lid of automobile handrail box, so that rotor 2 is connected with lid, when opening or close lid, lid rotor driven 2 rotates.As shown in Figure 4, intermediate portion 202 offers the shoulder hole (not indicating in figure) run through up and down, and preferably, the curve bath 2011 of joint 201 may extend in this shoulder hole, to strengthen the soundness that joint 201 is connected with intermediate portion 202.
When rotation damper of the present utility model is installed, first in annular housing 104, appropriate viscous fluid 4 is injected, and rotor 2 to be inserted in housing 1 and to be rotationally connected with it, then by anti-convulsion 1011, housing 1 is installed on the body of automobile handrail box, finally, by the joint 201 of rotor 2, rotor 2 is connected with the lid of automobile handrail box.
When opening or close lid, lid rotor driven 2 rotates, viscous fluid 4 in annular housing 104 is stirred to make its blade part 203, produce shearing force, thus viscous fluid 4 pairs of blade parts 203 form damping force, slow down the rotational velocity of rotor 2, simultaneously because blade part 203 end opens has rectangular indentation 2031, make, in annular housing 104, more viscous fluid 4 to be housed, further increase damping force, improve the damping of rotation damper, lid slowly can be opened or close.
In addition, the viscosity of viscous fluid 4 is larger, and the damping force of generation is larger, and lid motion is slower.The lid of Different Weight should select the viscous fluid 4 of different viscosity, and to prevent because lid is overweight, the damping force that the fluid that viscosity is little produces is not enough to the deadweight of opposing lid and lid is fiercely closed; Or prevent because lid kicks the beam, it is too slow that the damping force that tough fluid produces makes to open or close lid.
Above, be only schematic description of the present utility model, it will be recognized by those skilled in the art that on the basis of not departing from working principle of the present utility model, can make multiple improvement to the utility model, this all belongs to protection domain of the present utility model.
