Abstract
The utility model discloses a memory alloy part combination damping device, comprising a memory alloy spring sheet (1) and a corner strip (3); the memory alloy spring sheet (1) and the corner strip (3) are arranged in a slot inside an electric case face to face; the damping device also comprises a supporting circuit board (2); the shape of the memory alloy spring sheet (1) is an arc-shaped spring sheet and one vertical side thereof is an installation surface; when the number of the memory alloy spring sheet (1) is more than 1, the installation surface can be a shared bar-shaped installation surface. The memory alloy part combination damping device can sufficiently play the characteristic of different springs by the spring combination damping of different types, mutually complements the advantages, and has better anti-vibration and damping effects, less installation space for anti-vibration and damping and lighter weight.
Description
Technical field
The utility model relates to a kind of spring assembly vibration damping equipment, especially for the vibration damping and vibration isolation device little bulk of cabinet circuit board, the combination of inhomogeneity memory alloy spring.
Background technique
Functional for guaranteeing the electronic cabinet interior circuit board, the vibration isolation and damping of electronic cabinet is had relatively high expectations.General rigidity with metal framework intensifier circuit plate, with the vibratory response value of minimizing circuit board, but the weight of this device is bigger than normal, and effectiveness in vibration suppression is limited.Also have employing in the electronic cabinet slot skewback to be installed, the method that compresses circuit plugboard with the adjusting long bolt is come vibration damping, but the part that this vibration damping mode is used is on the high side, and because vibratory response is bigger, still has the possibility that makes electronic device lose efficacy or damage.Simultaneously, these two kinds of vibration damping equipments position that takes up room is bigger.When independent employing memory alloy spring vibration damping and vibration isolation, because chassis space is less, superelasticity vibration damping deformation space is limited, surpasses still might make the circuit board overload and electronic device was lost efficacy behind its curve platform to damage.
Domestic and international by retrieval pertinent literature is not seen and is utilized memory alloy spring to be combined in the report of the device and method of small space vibration damping.
The model utility content
Technology of the present utility model is dealt with problems and is: overcome the deficiencies in the prior art, a kind of memory alloy spare combination vibration damping equipment that uses in little space is provided.
Technical solution of the present utility model is: memory alloy spare combination vibration damping equipment, comprise memory alloy spring sheet and memory alloy angle bead composition, memory alloy spring sheet and memory alloy angle bead are installed in the interior slot of electronic cabinet in opposite directions, support the circuit board in the slot.
Described memory alloy spring sheet be shaped as arc-shaped spring piece, in its vertical side one attachment face is arranged.The quantity of described memory alloy spring sheet is during greater than one, and its attachment face is a shared bar shaped attachment face.
Working principle of the present utility model is: the vibration damping and vibration isolation installing space of cabinet slot interior circuit board is very little, and the damping effect space is littler.Memory alloy material has superelasticity and high damping, after external force arrives certain value, only increases displacement, active force does not increase, the support stiffness of circuit board is descended, and response frequency moves down and leaves the frequency zones of former peak value, can reach the final purpose of memory alloy spring vibration damping and vibration isolation.
Be contained in the slot with good, hyperelastic memory alloy arc-shaped spring piece of damping and amortization and memory alloy angle bead, dissimilar superelasticity spring assembly vibration dampings, guaranteed circuit board reliable mechanical loading condition in electronic cabinet.
The utility model advantage compared with prior art is:
1,, can give full play to the characteristic of different springs, complementary advantage, vibration damping and vibration isolation better effects if by adopting the memory alloy spring sheet and the spring assembly vibration damping of memory alloy angle bead at small spaces such as electronic cabinets.
2, adopt the little line segment contact circuit of arc memory alloy spring sheet plate, can play a part to support; The memory alloy angle bead has increased the local support rigidity of circuit board by line or face contact circuit plate, reduces magnification factor.
3, a plurality of memory alloy spring sheets and the installation that is connected as a single entity under the situation that does not take more useful spaces, have further strengthened effectiveness in vibration suppression.

Fig. 2 is a memory alloy angle bead of the present utility model;
Fig. 3 is the vertical installment state schematic representation of circuit board in slot;
Fig. 4 is circuit board horizontal installment state schematic representation that dissects in slot;
Fig. 5 is preceding low magnitude vibration response curve for the 0.7g circuit board shakes;
Fig. 6 is back low magnitude vibration response curve for the 0.7g circuit board shakes.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Memory alloy spare combination vibration damping equipment of the present utility model is made up of memory alloy spring sheet 1 and memory alloy angle bead 3.Memory alloy spring sheet 1 is an arc, is illustrated in figure 1 as the profile of a plurality of spring sheet combinations.Figure 2 shows that memory alloy angle bead 3, form by orthogonal two planes.
Among Fig. 3, circuit board 2 is vertically placed in slot, the circuit board 2 that spring sheet 1 and angle bead 3 support in the slot 4, and spring sheet 1 contacts with circuit board 2 lines, and angle bead 3 contacts with 2 of circuit boards or the line contact.Among Fig. 4, circuit board 2 is laterally placed in slot 4, the circuit board 2 that spring sheet 1 and angle bead 3 support in the slot 4, and spring sheet 1 contacts with circuit board 2 lines, and angle bead 3 contacts with 2 of circuit boards or the line contact.
Fig. 5 is the vibration response curve of the low magnitude of 0.7g, and Fig. 6 is the back vibration response curve that hangs down magnitude for 0.7g shakes.Curve A is the contrast by Fig. 5 and Fig. 6 among the figure, can see that big variation does not take place the vibratory response characteristic, illustrates that the rigidity of cabinet circuit board does not become, and has passed through vibration test.
