Description
Technical field
The present invention relates to a kind of TRT, more particularly to a kind of TRT that pressing force is converted to electric power.
Background technology
Entitled " flat-type miniature power generating device ", Authorization Notice No. are：The U of CN 202334252 Chinese invention discloses
A kind of TRT.This TRT has the following disadvantages：
1) it requires that conductive coil (2) and the position of permanent magnet (3) are relatively fixed, but permanent magnet (3) present position is true
On be difficult to it is relatively-stationary with conductive coil (2), although it is contemplated that skeleton (9) and permanent magnet by conductive coil
(3) it is installed on same matrix and both be relatively fixed is realized with this, but so needs to increase part and production stage, cost
It can increase；
2) shape of soft magnetic bodies (1) is " U "-shaped, " u "-shaped one of arm end formed with press section for
By dynamic, but on the one hand to cause soft magnetic bodies (1) to be difficult to be put into conductive coil (2) internal for such structure, on the other hand also results in
Disengaging time between soft magnetic bodies (1) and permanent magnet (3) is elongated.For previous problem herein, the solution of above-mentioned document
Method is that just soft magnetic bodies (1) were placed into by upper casing (10) and lower casing before conductive coil (2) is wound on skeleton (9)
(11) skeleton (9) formed is internal, then again by conductive coil (2) coiling to skeleton (9), but significantly with soft magnetic bodies
(1) further around line and inconvenience on skeleton (9)；For latter problem herein, the shape of soft magnetic bodies (1) just determines pressing
Portion to the line between the fulcrum of soft magnetic bodies (1) can not entirely fall within soft magnetic bodies (1) physically, and external force F acts on press section
When, soft magnetic bodies (1) will also supervene unavoidable distortion deformation in addition to normal deflection deformation is produced, and torsional deformation causes
A part for soft magnetic bodies (1) first separates with permanent magnet (3), and then both are kept completely separate again, and this will have a strong impact on generating efficiency.
Then need to be improved by the structure of power generation device to current, to obtain the more excellent product of effect.
The content of the invention
The present invention provides a kind of push type efficient generating apparatus, and it has the advantages that, and generating efficiency is high, it is durable to stablize.
Using following technical scheme：
A kind of push type efficient generating apparatus, including coil holder, coil and permanent magnet；The coil is wound in the coil
Seat is outside；Formed with action chamber in the coil holder, the action intracavitary be provided with can be rotated relative to the coil holder the
One soft magnetic bodies；Especially, the action chamber is single radial cut chamber；With the opening of action chamber it is mutually remote be action chamber bottom；Institute
State the bottom that permanent magnet is fixed on the coil holder and is in the action chamber；First soft magnetic bodies are the flat of vertical bar shaped
Part, one of the first soft magnetic bodies stretch out in the action chamber；It is additionally provided with the second soft magnetic bodies and the 3rd soft magnetic bodies；Second soft magnetic bodies
One is in close contact, the second soft magnetic bodies from the bottom extended transversely into action chamber of action chamber with a pole of the permanent magnet

It extend into the opening of action chamber.
The operation principle of this push type efficient generating apparatus is as follows：
The position that first soft magnetic bodies stretch out in action chamber is the effector position of this TRT, external force forward and reverse
Power presses the position will be so that the first soft magnetic bodies correspond to rotates forward and rotate backward, so that the first soft magnetic bodies pair
The one kind that should be rested in two kinds of operating positions.Under a kind of operating position, one of the first soft magnetic bodies is and the second soft magnetic bodies
Be in action one of bottom of chamber portion contact, the other ends of the first soft magnetic bodies is to be in action chamber opening with the 3rd soft magnetic bodies
One contact.Under another operating position, one of the first soft magnetic bodies is to act bottom of chamber with being in for the 3rd soft magnetic bodies
One of portion contact, the other ends of the first soft magnetic bodies is contacted with one that is in action chamber opening of the second soft magnetic bodies.
Due to the magnetic direction Jing Guo coil inside under a kind of operating position be with another operating position be it is opposite, in
When being that the first soft magnetic bodies switch between two kinds of operating positions, quick become occurs for the magnetic flux of the first soft magnetic bodies
Change, so that quick change occurs by the magnetic flux of coil, induced-current will be produced on coil, is available for external circuit to make
With.
Second soft magnetic bodies and the 3rd soft magnetic bodies can be the flat pieces that profile is " u "-shaped, the second soft magnetic bodies and the
Three soft magnetic bodies are arranged on the coil holder parallel to each other, and are arranged on the same side of coil holder.
Second soft magnetic bodies and the 3rd soft magnetic bodies can be the flat pieces that profile is " u "-shaped, the second soft magnetic bodies and the
Three soft magnetic bodies are arranged on the coil holder parallel to each other, and the second soft magnetic bodies are arranged on the side of coil holder, the 3rd soft magnetic bodies
It is arranged on the opposite side of coil holder.
Second soft magnetic bodies and the 3rd soft magnetic bodies can also be using such structures：It is the flat of " u "-shaped by profile
Part is made, and the bottom of the " u "-shaped of the flat pieces has been bending 90 ° with respect to two vertical parts of " u "-shaped；Second soft magnetic bodies set online
The side of ring support, the 3rd soft magnetic bodies are arranged on the opposite side of coil holder.Pass through such technical scheme, the second soft magnetic bodies and the 3rd
The distance of soft magnetic bodies becomes big, can avoid the excessive counteracting in magnetic field, improves generated energy, while also ensure that the volume of TRT not
It can increase.
As an improvement, first soft magnetic bodies, which stretch out in act chamber one, is preferably additionally provided with energy storage shell fragment.So
The speed that the first soft magnetic bodies switch between two kinds of operating positions can be further improved, improves power generation performance and power generation stabilization
Property.
Two rotation branch of the first soft magnetic bodies as described in mutually faced are preferably also provided with the inwall of the action chamber
The fulcrum of point.
In addition, it may also include a transmission bracket；The transmission bracket includes：Base, the first lever piece, the second lever piece
