Abstract
The utility model relates to a magnetic buffer structure for small and medium size damper, comprising a guide member and an active member which move relatively, and a magnetic element which is respectively fixed on the guide member and the active member and forms magnetic exclusive effect, wherein the guide member and the active member which move relatively limit and guide movement direction, two magnetic elements forming magnetic exclusive force form a group, the opposite faces thereof are magnetic poles with the same polarity of permanent magnets, so that when two permanent magnets of each group are close to each other, magnetic exclusive force is generated. Since the magnetic exclusive force is in an increasing trend when the two magnetic elements are closed up mutually, damage caused by outside vibration to the member to be protected is effectively alleviated by using the two magnetic exclusive elements as the magnetic buffer structure for small and medium size damper.
Description
Technical field
The utility model belongs to the small-sized machine damping device, particularly the buffer structure of using towards middle-size and small-size damping device.
Background technique
Vibrations are ubiquitous physical phenomenons in the actual life, and in most cases, the existence meeting of vibrations has a negative impact to the operation of various device and device.Existing middle-size and small-size damping device generally adopts component such as rubber and spring that the conduction that shakes is cushioned and isolates, and the damping effect that reaches is not ideal.
The model utility content
In view of this, the utility model proposes a kind of homopolarity mutual exclusion characteristic of magnetic material that adopts and produce the structure of non-linear cushion effect, thereby the elastic force of obviously having improved elastic element in the passive energy dissipation mechanism is the narrow problem of damper mechanism work bandwidth that linear change caused substantially.
The magnetic cushion structure that the utility model proposes comprises guiding element, movable part and some magnetic elements.Described magnetic element is individually fixed on guiding element and the movable part.The feature of this buffer structure is: described guiding element can be relative movable with movable part, and both mate the formation guide structure; Described its opposing side of magnetic element that is individually fixed on guiding element and the movable part is a like pole, produces repulsive interaction.
Wherein, described guiding element and the guiding fit system of movable part can be that to be slidingly matched also can be to roll to cooperate.
Wherein, described guiding element and the movable part shape in the guiding cooperation place can be that cylinder, circular hole cooperate also can be that the polygonal post cooperates with polygonal hole or groove.
Wherein, described magnetic element is to use in pairs.
Wherein, described magnetic element can be individually fixed in the arbitrary position of guiding element and movable part.
Wherein, the described magnetic element that is fixed on guiding element and the movable part can be a pair of also can be arbitrarily how right.
Wherein, the shape of described magnetic element can be an arbitrary shape.
Wherein, the material of described magnetic element can be alloy permanent-magnet material, ferrite permanent-magnet materials or hybrid type permanent-magnet material.
Damping effect is good in actual use for the utility model magnetic cushion structure, compare with the device that does not use this structure, use its effective bandwidth of operation of damping device of this damping structure obviously to increase, this mainly has benefited from the magnetic repulsive interaction is accelerated growth apart from shortening with magnetic element characteristic.The damping device damping of using this model utility magnetic cushion structure in the practical application fast, stable, and adaptability is wider, proves that this structure is a kind of new design of practicability and progressive widely that has.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model active vibration damping device is described in further detail.
Embodiment one: consult Fig. 1, guiding element 102 and movable part 104 are that cylinder, circular hole are slidingly matched herein, the component movement guide structure, magnetic element herein is upper magnetic ring 101 and following magnet ring 103, magnetic pole of the same name is relative installs for upper magnetic ring 101 and following magnet ring 103, be individually fixed in guiding element 102 step ends and movable part 104 upper ends, when movable part 104 relative guiding element 102 motions make the magnet ring pitch smaller, magnetic repulsive interaction between upper magnetic ring 101 and the following magnet ring 103 will be acceleration tendency and increase, thereby form the impulse force parts that slow down of a characteristic good.
Embodiment two: consult Fig. 2, guiding element 202 herein, 205 and the permanent magnet movable supporting plate 203 that plays the movable part effect be that the bicylindrical circular hole is slidingly matched, form the motion guide structure, guiding element 202 is housed on the permanent magnet dunnage 201,205, be fixed with a permanent magnet 206 simultaneously, be fixed with another piece permanent magnet 204 on the movable supporting plate 203 relative with it, permanent magnet 206 is installed with magnetic pole relative mode of the same name with permanent magnet 204, thereby between them, form certain magnetic repulsive interaction, when movable supporting plate 203 relative guiding elements 202,205 motions make permanent magnet 204, during 206 pitch smaller, magnetic repulsive interaction between the permanent magnet 204 and 206 will be acceleration tendency and increase, thereby form the impulse force parts that slow down of a characteristic good.
Fig. 3 is the application schematic representation of embodiment one on the miniaturized electronics damping device, wherein post patch 302, support post 304, base plate 305, guide upright post 306 forms the stationary frame structure with directional post, floating frame 301 and linear bearing 307 form the floating shock-absorbing structure, be installed on the two ends up and down of four support posts respectively based on eight groups of mutual exclusion magnet ring groups 303 of embodiment's one structure, constitute guide structure thereby formed one by guide upright post 306 and linear bearing 307, form the shock-damping structure of bidirectional buffering vibration damper by eight groups of mutual exclusion magnet ring groups.When the external world has the vibrations of Vertical direction to import into, just conduct on a small quantity on the electronic equipment that is fixed on the floating frame after significantly the filtering of the double-acting shock absorber that vibrations will constitute by eight groups of magnet rings.This structural damping effect is good, and the damping Duty cycle does not use the homogeneous structure of magnetically damped device that significant increase has been arranged.
The above is detailed description and accompanying drawing that two preferred embodiments of the present utility model and typical case use, is not that scope of the present utility model limits.For method and apparatus of the present utility model, all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
