The device is one of ideal energy solution schemes in a micro-power wireless sensing network. An adaptation scope is wide. Cost is low. The size is small and the structure is simple.

Staggered biting connecions magnetic TRT

Technical field

The utility model relates to a kind of magnetic TRT, particularly a kind of staggered biting connecions magnetic TRT.

Background technology

Present existing magnetic TRT has multiple, and wherein the most commonly used is exactly generator.But the magnetic TRT volume that with the generator is representative is bigger, is not suitable for the strict environmental condition of volume restrictions, and is the magnetic TRT of representative when converting mechanical energy into electric energy with the generator, and requiring mechanical energy must be the form of rotating.This just makes under some conditions, is that the magnetic TRT of representative is also inapplicable with the generator.Vigorously advocate under the energy-conserving and environment-protective in country, the demand of a lot of special miniature power generating devices has appearred in the collection of energy field, and this is traditional often is that the magnetic TRT of representative is implacable with the generator.In the emerging Internet of Things industry, if adopt traditional battery supply then can cause problems such as maintenance cost is high, seriously polluted, the power issue of micropower radio sensing network also becomes the bottleneck problem that the bar networking is popularized.

The utility model content

The technical problem that the utility model will solve provides a kind of miniature staggered biting connecions magnetic TRT, can convert the mechanical energy of short stroke translation into electric energy, is specially adapted to short stroke translation environment, its wide accommodation, and cost is low.

For addressing the above problem, the utility model adopts following technical scheme: comprise permanent magnet, soft magnetic material, iron core and coil; Wherein the permanent magnet two ends connect soft magnetic material, and two magnetic poles constitute " C " type magnet towards same direction.Iron core one end wraparound does not connect to original not exit, and forms two branches and constitute " E " type magnetic circuit in the same direction with exit not.Coil around " E " sections core middle exit on.With " C " type magnet and the staggered interlock of " E " type magnetic circuit that the front obtains, control the break-make of " E " type magnetic circuit through the motion of " C " type magnet.Utilize electromagnetic induction to constitute staggered biting connecions magnetic electrification structure.

Further, wherein " C " type magnet or " E " type magnetic circuit can connect an elastic device to said staggered biting connecions magnetic TRT.

Further, said elastic device can be spring or shell fragment.

Further, the formation connected mode of said " C " type magnet is the side of permanent magnet end face contact soft magnetic material end.

The utility model biting connecions magnetic TRT that interlocks; Because having overcome is the shortcoming that numerous magnetic generating device structures are complicated, volume is bigger of representative with the generator; Can convert the mechanical energy of short stroke translation into electric energy, pollution-free, be particularly suitable for the application scenario in little collection of energy field; Like switch, button, vibration environment etc., also be one of micropower radio sensing network perfect energy sources solution.Its wide accommodation, cost is low, and volume is little, and is pollution-free, simple in structure.

Embodiment

Fig. 2 sees from figure for " C " type magnet is drawn the state that is with the conducting of " E " type magnetic circuit downwards by spring, because the effect of power; " C " shape magnet moves downward and is adsorbed on the lower end at this moment; The space occurs between the first half " C " type magnet and iron core (2), magnetic resistance is bigger, can be considered blocking-up; The magnetized soft magnetic material of the latter half (3) absorption iron core (2), the magnetic circuit conducting.The overwhelming majority magnetic line of force passes through from the latter half magnetic circuit, and the magnetic direction in the coil (1) is shown in arrow among the figure.It is thus clear that magnetic field intensity is identical with Fig. 1 in the coil at this moment; Magnetic direction is opposite; Consider the number of turns and the sectional area of coil (1), can know the variation that has caused a bigger magnetic flux, in coil (1), produce electric energy thus; Can outwards export energy storage device to, or through offering relevant micropower equipment behind the rectifying and voltage-stabilizing.If possess elastic device (5), have an effect this moment.The resilient force of elastic devices (5) makes " C " type magnet separate with the iron core that is adsorbed (2) end on " C " type magnet, under the effect of elastic force, gets back to the state among Fig. 1.Be similar to the process to Fig. 2 by Fig. 1, this recovery process can cause the variation of a bigger magnetic flux in the coil (1) again, and electric energy can outwards be provided once more.With do not have elastic device (5) to compare, be equivalent to generating efficiency and improved 1 times.Simultaneously, originally two stable states of two ends absorption become and have only a stable state.When not having elastic device (5), TRT is the dial-up pattern; When possessing elastic device (5), TRT is the key pattern, can select for use according to concrete demand.Elastic device (5) can act on " C " type magnet of permanent magnet (4) and soft magnetic material (8) composition, also can act on (2) on the iron core, and the relative motion that makes both formations comprise adsorbed state gets final product.

Fig. 3 is the corresponding a kind of stereogram of the utility model.Can see that the far-end of iron core (2) draws, walk around coil (1) near iron core (2) near-end, and fork is two ends near iron core (2) near-end, splits in the upper and lower both sides of iron core (2) near-end, constitutes structural " E " type magnetic circuit from rear side.Coil (1) is in the branch of centre.The direction of magnetization of permanent magnet (4) is a upward and downward, and the side of end face contact soft magnetic material (3) end with soft magnetic material (3) magnetization at two ends, is equivalent to the two poles of the earth of permanent magnet (4) are guided to same, constitutes " C " shape magnet." C " type magnet is staggeredly placed with " E " type magnetic circuit, controls the break-make of " E " type magnetic circuit through moving up and down of " C " type magnet." C " type magnet is in the state of absorption lower end among the figure, and most magnetic lines of force pass through from the lower end of iron core (2) fork.If " C " sections core is because the effect of power is adsorbed on the upper end, most magnetic lines of force will pass through from the upper end of iron core (2) fork, and the magnetic flux in the coil (1) will be reverse.Do not relate to elastic device (5) among the figure.Elastic device (5) can be a spring, also can be the shell fragment that is stuck on the shell, also can be other elastic devices.The elastic force of elastic device (5) is moderate, if too little, the soft magnetic material (3) of absorption is mutually separated with iron core (2) end, if too big, then can require excessive generating active force, and the influence generating is experienced and the generating effect.Its elastic force of desirable elastic device (5) gets final product slightly greatly than the absorption affinity of soft magnetic material (3) with iron core (2).Want suitably in the gap of " E " sections core (2) and " C " type magnet, and both non-adsorbable intermediate states then may appear in excesssive gap, and the gap is too small, and then the influence generating is experienced, even cause all distortion of absorption each other of two ends.6-1,6-2 are the baffle plate that fixed coil is used.

Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
