Description
Technical field
The invention belongs to five metals manufacturing, static discharge and electrostatic hazard guard technology field, relate to a kind of portable unit of energy dissipating human body electrostatic, especially a kind of key with dissipating human body electrostatic harassing attack function.
Background technology
The static electricity on human body is a kind of common phenomena in the daily life, it is owing to human body walking, operation, or with the contact of other object, separate, or make human body positive-negative polarity electric charge disequilibrium because of reasons such as electrostatic induction, space charge absorption, and then the electric charge that presents certain polarity on macroscopic view gathers, make the human body above earth potential non-vanishing, formed electrostatic energy over the ground.When human body over the ground electrostatic potential enough high (＞3kV), or electrostatic energy enough greatly (＞1 * 10
-4J) time, just might produce static discharge to parts such as metal door and windows, the lighter produces human body and harasses, and weight person may cause the components and parts puncture, and electronic equipment is malfunctioning, even safe disasters such as initiation fire, blast.Therefore, dissipating human body electrostatic especially has very important significance to the people that work under inflammable and explosive and electrostatic sensitive environment to people's daily life and work.
In modern way of life, people are difficult to forget the material that is easy to generate and accumulates static, as macromolecular materials such as chemical fibre, plastics, rubber.A large amount of uses of these materials are bringing the comfortable while easily also to make us suffer the harassment of static more and more at large to people's life.Under dry environment, human body can reach 18kV from the electrostatic potential that rubbery foam back cushion seat produces immediately, and the electrostatic potential that produces when walking on carpet can reach 35kV, and the electrostatic potential that produces when undressing on insulation ground reaches as high as 60kV.High electrostatic potential like this is stored in tens of extremely human body electrostatic capacitance between hundreds of pico farads, and (majority is distributed on 100～350pF), electrostatic energy can reach a few mJ to tens mJ, produce very big electric shock intensity and discharge spark during release, though not fatal, easily the people is produced the panic and pain of electric shock.
At present, the method for dissipating human body electrostatic mainly contains two kinds, and the one, by the method increase ambient humidity of humidification, the 2nd, by wearing anti-electrostatic clothing, shoes and hats, lay the conductive flooring, apparatus such as use antistatic tables and chairs carry out electrostatic grounding with human body.Therefore use but these two kinds of methods only are applicable under particular surroundings, but can reduce people's mobility, comfortableness in daily life and to dress, to living environment diversity and personalized demand.
The best method of dissipating human body electrostatic is to carry a kind of small and exquisite static discharge device in the daily life, and the static that can at any time human body be produced dissipates the static electricity on human body by contacting with ground device.But this electric discharge device can not be realized by the ironware short circuit simply, be on the one hand because when electrostatic potential is very high, can produce electric-shock feeling to human body equally by the ironware short circuit, also can therefore produce discharge spark on the other hand, there is potential hazard in inflammable and explosive place, more static electricity on human body's energy can not be used.
Key be people's daily life the unlocking tool that must carry, static is discharged resistance, storage capacitor and charging circuit to be equal to key and to combine and constitute the device with dissipating human body electrostatic function, when people open the door or contact with ground device, static electricity on human body's energy is transferred on the energy-storage capacitor, not only suppressed static electricity on human body's harassment, and well static electricity on human body's energy is used for the auxiliary charging of remote-control key, prolong the application life of remote-control key.This device with dissipating human body electrostatic function yet there are no report by literature search so far.
Summary of the invention
The objective of the invention is to overcome deficiency and the defective that exists in existing static electricity on human body's dissipation technology, a kind of key apparatus with dissipating human body electrostatic harassing attack function is provided.Wood invention does not change the basic training usefulness of key unlocking, utilizes function but increased dissipate function and static electricity on human body's energy of static electricity on human body, has brought into play the portability of key, and when consciously or unconsciously using key, safe ready ground dissipates the static electricity on human body.
Technical scheme of the present invention is:
The dissipating human body electrostatic harassing attack key comprises key body, electrostatic dissipation circuit, charging circuit and door lock remote control circuit four parts.It is characterized in that: electrostatic dissipation circuit, charging circuit and door lock remote control circuit are installed in the shank of the key of being made by plastics or rubber, the shank of the key outward flange embedded with metal bar, bonding jumper can not directly link to each other with the metal key bar, and closest approach air line distance is more than or equal to 10mm.The electrostatic dissipation circuit is made up of current-limiting resistance and energy storage capacitor in series, and electric capacity one end is connected to the key bar afterbody that is made of metal, and resistance one end then links to each other with the bonding jumper that the shank of the key is inlayed outward.The selection of current-limiting resistance should guarantee the human body electrostatic potential when 20～30kV, and key bar ground connection human body should not had pain, also tangible electric discharge phenomena should not occur, generally chooses the film resistance of 1-2M Ω, 1/4W.The choosing of storage capacitor should take into full account the probability and size that human body electrostatic capacitance and electrostatic potential occur.Human body electrostatic capacitance is generally 100～350pF, and electrostatic potential has more about present 5kV, according to electrostatic energy formula CU
2/ 2, consider the loss of current-limiting resistance, on energy-storage capacitor, obtain 30V voltage, then storage capacitor should be chosen the low current leakage capacitor of 3～10uF.When holding the shank of the key, and during with ground device such as key bar contact doors, static electricity on human body's energy will be transferred on the energy-storage capacitor by this circuit.Because the charged polarity of human body can be influenced by several factors, has uncertainty, therefore use full bridge rectifier that the voltage transition on the energy-storage capacitor is used for definite polar voltages, its output is connected to door lock remote control circuit battery two ends, can utilize the energy-storage capacitor energy stored to charge the battery.Diode and capacity cell should be selected the minimum device of leakage current in the charging circuit, just can highlight the effect of utilizing of static electricity on human body's energy.
Effect of the present invention and benefit are owing to circuit that the static electricity on human body is dissipated, the electrostatic energy conversion stores charging circuit, the door lock remote control circuit combines with the key of carrying, do not increasing under the situation that people carry burden, opening the door moment consciously or unconsciously, with static electricity on human body's safety, dissipate easily, having solved the existing static electricity on human body device that dissipates should not carry, influence the deficiency of personal lifestyle quality, promptly can eliminate static electricity on human body's harassment, prevent the static fear, increased the safety of people again, static electricity on human body's energy can also be used simultaneously in the activity of electrostatic sensitive place.
