Abstract
The utility model discloses an information tactile sense acquisition device, which is characterized in that an upper surface of a case body is provided with a key matrix; the keys are respectively provided with a probe; a shape memory alloy rod is arranged blow the key and inside the case; electrified conductive cloth is arranged blow the shape memory alloy rod and inside the case; the shape memory alloy rod is connected, through lead wire, to a signal connector which is arranged on the case. When a certain key is pressed, the shape memory alloy rod is deformed under the force and is in contact with the conductive cloth, and an electrical signal is fed to the shape memory alloy rod. The electrical signal is connected to a computer through lead wire, a signal connector and a data line. The computer transmits the electrical signal, through the data line, the signal connector and the lead wire, to the memory alloy rod of another computer which is connected the computer through network. Under the action of the electrical signal, the shape memory alloy rod is deformed to enable the probe on the key to be sensed by a hand of an operator. The device can carry out tactile sense intercommunion via the network, and especially suitable for the intercommunion of blind people through the network.
Description
Technical field:
The utility model relates to computer annex, specifically a kind of sense of touch harvester of information.
Background technology:
As everyone knows, sense of touch transmission interaction technique all has important use to be worth in a lot of fields.External many famous colleges and universities and scientific research institution are all in the research work of carrying out power touch feeling model building and interface arrangement.Stanford Univ USA, Harvard University, Northwest University, University of Washington, Massachusetts Institute of Technology (MIT) and Johns Hopkins University etc. have successively carried out the physiology of power touch feeling model building, power tactile sense reproduction and power sense of touch towards distant operation and pseudo operation and the research of mental mechanism.On the whole, the research of power haptic device is an emerging research field, and achievement in research is all under test.
Marmem (Shape Memory Metal) is a kind of particular components, after martensitic excellent bending, is heated as austenite again; After the cooling, revert to original-shape again.Each contact element all with a very thin light-duty marmem SMM (linking to each other) as Ti-Ni titanium-nickel alloy, when the SMM, it generates heat because of Joule effect at electric current.This can cause marmem to shrink, and drives the contact thus and moves, and the top cover by matrix stretches out, and contacts with hand.When failure of current, the cooling of SMM line drives the contact and is recovered in the drive array.Behind the LED lamp with receiving terminal in this device replacement two machine communication, just can realize the reproduction of sense of touch substantially.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can gather, transmit, produce the sense of touch harvester of sense of touch.
The utility model can reach by following measure:
A kind of sense of touch harvester, be provided with box body, cartridge upper surface is provided with key-press matrix, button is provided with probe, box body is interior, button has the marmem rod, be provided with charged conductive fabric in marmem rod below, the box body, the marmem rod is connected with modular multiple terminal block signal connector on being located at box body through lead.
The utility model is when pressing a certain button, marmem rod stress deformation contacts with conductive fabric, be connected with electric signal on the marmem rod, electric signal leads to the modular multiple terminal block signal connector through lead, the modular multiple terminal block signal connector is connected with computing machine through data line, electric signal is just imported in the computing machine, computing machine passes through data line to electric signal by being provided with of the network and other end computing machine of the present utility model, the modular multiple terminal block signal connector, lead is passed to the marmem rod, the marmem rod hand that makes probe on the button spy the operator that deforms under the electric signal effect produces sense of touch, the utility model can utilize network to carry out sense of touch and exchange, be particularly useful for the blind person, A has on the box face with hand and writes, this information can be immediately be positioned at the left hand lower box surface through what network passed to other end B, makes A, the B two ends can well exchange by sense of touch.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, a kind of sense of touch harvester, be provided with box body 1, box body 1 upper surface is provided with button 2 matrixes, button 2 is provided with probe 3, in the box body 1, button 2 has marmem rod 4, marmem rod 4 belows, be provided with charged conductive fabric 5 in the box body 1, marmem rod 4 is connected with modular multiple terminal block signal connector 6 on being located at box body through lead, above-mentioned each ingredient is same as the prior art, this does not give unnecessary details, when pressing a certain button, marmem rod stress deformation contacts with conductive fabric, be connected with electric signal on the marmem rod, electric signal leads to the modular multiple terminal block signal connector through lead, the modular multiple terminal block signal connector is connected with computing machine through data line, electric signal is just imported in the computing machine, computing machine passes through data line to electric signal by being provided with of the network and other end computing machine of the present utility model, the modular multiple terminal block signal connector, lead is passed to the marmem rod, the marmem rod hand that makes probe on the button spy the operator that deforms under the electric signal effect produces sense of touch, the utility model can utilize network to carry out sense of touch and exchange, be particularly useful for the blind person, A has on the box face with hand and writes, this information can be immediately be positioned at the left hand lower box surface through what network passed to other end B, makes A, the B two ends can well exchange by sense of touch.
