In the embodiments of the present invention, the symbol "/" indicates a meaning having both functions. And the symbol "A and/or B" indicates that the combination between the front and rear objects connected by the symbol includes three cases of "A", "B", "A and B".
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
When the embodiment of the present invention is implemented in specific applications, the first permanent magnet 11 and the second permanent magnet 12 may adopt an annular structure, a bar structure, a cylindrical structure, etc., but through practical tests, the permanent magnet with the annular structure can bring about that the relative fixing arrangement distance is optimal, and the fixing is relatively simple, convenient and stable. The details of which are set forth in the examples that follow.
This embodiment through a pair of homopolar annular permanent magnet of relatively fixed setting, and with the coil that annular permanent magnet is coupled, through the coil with the change of annular permanent magnet relative position improves the magnetic flux rate of change when the coil response, and then improves the generated power from the power generation switch, guarantees remote response's reliability and stability.
In the embodiment of the present invention, the coupling manner between the permanent magnet assembly 1 and the coil 4 at least includes the following:
the first coupling mode:
the permanent magnet assembly 1 is directly inserted into the winding area of the coil 4, as shown in fig. 2, which is a schematic structural diagram of the coupling mode. As shown in fig. 2, the coil 4 may be pre-wound in a mold 41, and the mold 41 is provided with a through hole for penetrating the permanent magnet assembly 1, so that the electromagnetic assembly 1 can be disposed in the through hole of the mold 41 and can move back and forth in a direction parallel to the central axis of the through hole.
A second coupling mode:
the permanent magnet assembly 1 penetrates through the winding area of the coil 4, a U-shaped limiting groove 5 made of a magnetic material is additionally arranged in the winding area of the coil 4, and the U-shaped limiting groove 5 penetrates through the winding area of the coil 4, as shown in fig. 8, compared with the first coupling mode, the second coupling mode can further improve the variation of the magnetic flux in the coil 4 through the contact of the permanent magnet assembly 1 with the U-shaped limiting groove 5 in the movement process, so that the generated power is improved.
A third coupling mode:
the permanent magnet assembly 1 is arranged outside the winding area of the coil 4, and a U-shaped limiting groove made of a magnetic material (for example, a soft magnet) is arranged to penetrate through the winding area of the coil 4, as shown in fig. 15, when the position of the permanent magnet assembly 1 relative to the coil 4 changes, the permanent magnet assembly contacts with the U-shaped limiting groove made of the magnetic material, so that the magnetic flux direction of the U-shaped limiting groove 5 changes, and the coil 4 generates induced voltage.
In the second coupling mode and the third coupling mode, the adoption of the structure of the U-shaped limiting groove 5 and the permanent magnet assembly 1 is not the only mode for realizing the contact between the permanent magnet assembly 1 and the magnetic material penetrating through the winding area of the coil 4. In a specific alternative implementation manner of the present invention, the contact with the bar-shaped soft-magnetic body 6 during the movement of the permanent-magnetic component can also be realized by using the bar-shaped soft-magnetic body 6 (i.e. an alternative structure of the U-shaped limiting groove 5) and the permanent-magnetic component 1 with the metal supporting plate 132. As shown in fig. 4, wherein the length of the soft-magnetic body 6 is smaller than the distance between the support plates 132 on both sides of the permanent-magnetic assembly 1, so that when the permanent-magnetic assembly 1 completes the relative displacement with respect to the coil 4, it can contact both sides of the soft-magnetic body 6, respectively, thereby changing the magnetic flux density of the soft-magnetic body 6.
As a complete self-generating switch device applicable to the embodiment of the present invention, the device generally further includes a signal processing circuit board 8, as shown in fig. 14, specifically:
the interfaces at two ends of the coil 4 are connected to two ends of the power input interface of the signal processing circuit board 8, and are used for providing power input for each chip unit in the signal processing circuit board 8.
Example 2:
the embodiment of the present invention is based on the first coupling manner between the permanent magnet assembly 1 and the coil 4 proposed in embodiment 1, and further provides a feasible implementation scheme for the position change of the permanent magnet assembly 1 relative to the coil 4 and the relative fixed arrangement of the same poles of the first permanent magnet 11 and the second permanent magnet 12 in embodiment 1. As shown in fig. 2 and 3, the permanent magnet assembly 1 further includes a permanent magnet fixing member 13 besides the first permanent magnet 11 and the second permanent magnet 12, where the permanent magnet fixing member 13 is used to complete the homopolar relative fixing of the first permanent magnet 11 and the second permanent magnet 12, specifically:
the first permanent magnet 11 and the second permanent magnet 12 are oppositely arranged in the same pole; the connecting rod 131 of the permanent magnet fixing piece 13 penetrates through the hollow area of the first permanent magnet 11 and the hollow area of the second permanent magnet 12, and the supporting plates 132 of the permanent magnet fixing piece 13 are arranged at two ends of the connecting rod 131, so that the first permanent magnet 11 and the second permanent magnet 12 are oppositely fixed in the same pole;
the connecting rod 131 and the supporting plate 132 are preferably fixed by screws, that is, both ends of the connecting rod 131 are provided with screw holes, and the supporting plate 132 is provided with through holes corresponding to the screw holes, and the fixing of the connecting rod and the supporting plate is completed by screws; and, the one side supporting plate 132 and the connecting rod 131 can be integrally formed/welded in advance, and the other side supporting plate and the connecting rod can be fixed by screws, thereby further simplifying installation. Besides screw fixation, omega buckle fixation can be adopted, but the fixation effect is better.
The coil 4 is nested at the joint of the first permanent magnet 11 and the second permanent magnet 12, and when the relative position of the joint of the coil 4 and the first permanent magnet 11 and the second permanent magnet 12 changes, induced voltage is generated by the coil 4.
In a specific implementation, in order to ensure the coupling tightness between the first permanent magnet 11 and the second permanent magnet 12 and consider a situation that a large amount of power generation needs to be generated, the magnetic strength of the first permanent magnet 11 and the second permanent magnet 12 itself needs to be selected to be large, at this time, it is preferable that a gasket 14 (as shown in fig. 3) is additionally arranged at a position where the same poles of the first permanent magnet 11 and the second permanent magnet 12 are spliced in opposite directions, where the gasket 14 may be made of a plastic material or made of an inorganic material such as ceramic or silicon dioxide.
According to the embodiment of the invention, the pair of annular permanent magnets arranged in the same phase and the coil arranged around the joint of the annular permanent magnets are used, and the high-strength cutting magnetic induction line is generated through the change of the relative position of the joint of the coil and the annular permanent magnets, so that the self-generating capacity is improved.
Referring to fig. 5, a schematic diagram of the magnetic induction lines after the first permanent magnet 11 and the second permanent magnet 12 are arranged with the same poles facing each other (in which, the first permanent magnet 11 and the second permanent magnet 12 are arranged with the same poles facing each other, for example), and the effects are explained by the movement states of the spontaneous electric switching device shown in fig. 6 and 7. The moving mode of the connection position of the first permanent magnet 11 and the second permanent magnet 12 relative to the coil 4 at least includes the following modes:
moving from the middle to the left, for example, changing from the state of fig. 2 to the state of fig. 6;
moving from the middle to the right, for example, changing from the state of fig. 2 to the state of fig. 7;
the first moving mode and the second moving mode can be combined to realize, namely, a switch operation action corresponding to the self-generating switch device can be provided, namely, the plectrum/button which can drive the coil 4 or the permanent magnet assembly 1 to move back and forth is poked back and forth.
The moving mode III is moving from the left side to the right side, for example, changing from the state of FIG. 6 to the state of FIG. 7;
the fourth movement mode is to move from the right side to the left side, for example, from the state of fig. 7 to the state of fig. 6.
The above moving modes have a common characteristic that the connection point of the first permanent magnet 11 and the second permanent magnet 12 has a certain displacement in the coverage width area of the coil 4. As can be seen from fig. 5, the direction of the magnetic induction line at the connection point of the first permanent magnet 11 and the second permanent magnet 12 is rotated by 180 °, so that compared with the change of the magnetic flux relative to the coil, which is generated by the movement of only a single permanent magnet in the coil in the prior art, the solution of the embodiment of the present invention can further increase the variation of the magnetic flux, thereby effectively improving the problem of insufficient self-generating power in the prior art.
The structure and the corresponding implementation principle of the core essential component of the self-generating switch device are illustrated in embodiment 1 of the present invention, and the embodiment 1 usually needs to be provided with a limiting groove in a specific application environment, so that, in combination with embodiment 1 of the present invention, there is a feasible expansion scheme, as shown in fig. 13 and 3, the device further includes a U-shaped limiting groove 5, specifically:
the first assembly composed of the first permanent magnet 11, the second permanent magnet 12 and the permanent magnet fixing piece 13 is arranged in the slot position of the U-shaped limiting groove 5, and two arms of the U-shaped limiting groove 5 form a movable area of the first assembly.
Based on the application scenario of the U-shaped limiting groove 5, an optimized implementation manner also exists in the embodiment of the present invention, that is, the U-shaped limiting groove 5 is made of a magnetic material. With the layout structure shown in fig. 2 and referring to the working state of the self-generating switch device shown in fig. 6 and 7, the U-shaped limiting groove 5 is made of a magnetic material, and under the action of toggling or pressing, the permanent magnet assembly 1 can be driven to accelerate to complete the switching from the initial position to the target position (for example, the initial position is shown in fig. 3, and the target position is shown in fig. 6 or 7), so that the variation of the magnetic flux in the coil 4 in unit time is further increased, and a larger self-generating amount can be generated compared with the U-shaped limiting groove 5 which is not made of the magnetic material. Taking the polar structure of the permanent magnet assembly 1 shown in fig. 5 as an example, the U-shaped limiting groove 5 should be made into a magnetic structure with the inner side of the groove being the S pole and the outer side of the groove being the N pole. Moreover, in the present implementation scheme, the U-shaped limiting groove 5 may be made of a soft magnetic material, so that noise generated when the U-shaped limiting groove 5 and the permanent magnet assembly 1 are in contact with each other may be reduced. In practical application, the U-shaped limiting groove 5 made of the soft magnetic material can not meet the rigid limiting requirement, and at the moment, the U-shaped limiting groove 5 with a double-layer structure with an inner layer made of the soft magnetic material and an outer layer made of steel material can be used for meeting the rigid limiting requirement.
Example 3:
the embodiment of the present invention is based on the second coupling manner between the permanent magnet assembly 1 and the coil 4 proposed in embodiment 1, and further provides a feasible implementation scheme for the position change of the permanent magnet assembly 1 relative to the coil 4 and the relative fixed arrangement of the same poles of the first permanent magnet 11 and the second permanent magnet 12 in embodiment 1. As shown in fig. 8, in the embodiment of the present invention:
the coil 4 is arranged on the outer ring of a die 41 with two through holes, wherein a first through hole 411 of the die 41 is used for passing through the first permanent magnet 11 and the second permanent magnet 12 in the first assembly; the second through hole 412 of the die 41 is used for penetrating through the bottom plate of the U-shaped limiting groove 5. The installation of the die 41, the permanent magnet assembly 1 and the U-shaped limiting groove 5 may adopt a combined structure (as shown in fig. 8) in which the die 41 itself is used to cut the upper and lower sections of the first through hole 411 and the second through hole 412, and after the nesting structure of the die 41, the permanent magnet assembly 1 and the U-shaped limiting groove 5 is completed, the coil 4 is arranged on the outer ring of the die 41.
The difference between the position structure of the embodiment of the present invention (shown in fig. 8) and that of the embodiment 2 (shown in fig. 2) is that: the U-shaped limiting groove 5 and the permanent magnet assembly 1 are nested in the annular structure formed by the coil 4, so that the permanent magnet assembly 1 is stirred and generates displacement relative to the coil 4, and particularly when one end of the permanent magnet assembly 1 is contacted with one side wall of the U-shaped limiting groove 5, the permanent magnet assembly 1 changes the magnetic line density of the U-shaped limiting groove 5, the change intensity of the magnetic flux in the coil 4 is further improved, and the self-generating capacity is enhanced. Considering further that the supporting plate 132 is disposed between the permanent magnet assembly 1 and the U-shaped retaining groove 5, in order to increase the influence of the permanent magnet assembly 1 on the magnetic flux density of the U-shaped retaining groove 5 when reaching the target position (as shown in fig. 6 or fig. 7, that is, the supporting plate 132 contacts with the inner wall of the U-shaped retaining groove 5), it is preferable that the supporting plate 132 is made of a magnetizable metal material. However, the supporting plate 132 may be made of a plastic material having elasticity in order to reduce noise caused by the switching operation.
As an optional implementation scheme for driving the permanent magnet assembly 1 to move, specifically, an implementation manner of using a shifting piece is provided, as shown in fig. 9, the device further includes a switch shifting piece 7, and the following two implementation manners may be specifically adopted:
first, as shown in fig. 10, the switch moving piece 7 is connected to the supporting plate 132 of the permanent magnet fixing piece 13, so that the first assembly composed of the first permanent magnet 11, the second permanent magnet 12 and the permanent magnet fixing piece 13 moves back and forth relative to the coil 4 by moving the switch moving piece 7.
In the second mode, as shown in fig. 11, the switch paddle 7 is connected to a mold 41 for fixing the coil 4, so that the coil 4 can move back and forth relative to the first component by toggling the switch paddle 7. In the second pick mode, the supporting plate 132 can perform a limiting function, so that a more simplified structure is provided, and even the design requirement can be met without the U-shaped limiting groove 5 shown in fig. 11.
The implementation modes of the two layout switch plectrums 7 are feasible in specific implementation, wherein the plectrum mode I needs to provide extra moving space for the permanent magnet assembly 1 compared with the plectrum mode II, so that the volume of the whole self-generating switch device is larger compared with the plectrum mode II; in the second mode, the manufacturing cost is further increased because the fatigue problem of the connection interface between the coil 4 and the signal processing circuit board 8 during the back and forth movement is overcome. For example: for the first plectrum mode, the current output port of the coil 4 can be connected with the signal processing circuit board 8 only by common lead welding; for the second toggle piece mode, a corresponding combination structure of the spring plate and the slide rod needs to be arranged, the current output end of the coil 4 is respectively connected with the two spring plates, the spring plates keep contact with the slide rods when the coil 4 is toggled back and forth, and the two corresponding slide rods are respectively connected with the power input electrode on the signal processing circuit board 8.
It should be noted that fig. 10 and 11 only show one of the many ways that the switch pulling piece 7 can be coupled with the permanent magnet assembly 1, and the other way is similar to making the switch pulling piece 7 and the supporting plate 132 into an integral structure, i.e. using the groove wall of the switch pulling piece 7 to directly act as the supporting plate 132; or a through hole which can pass through the permanent magnet assembly 1 is arranged on the groove wall of the switch shifting piece 7, and the switch shifting piece 7 and the permanent magnet assembly 1 are coupled, and the like, and the invention belongs to the protection scope of the embodiment of the invention. In addition, as shown in fig. 10 and fig. 11, only one control mode of the dial is given, and in a specific implementation mode, it can also be accomplished by using a button, specifically, as shown in fig. 12, in order to adapt to the operation mode of the button, wherein the switch button 9 is fixed with the supporting plate 132 on one side of the permanent magnet assembly 1, and the supporting plate on the other side of the permanent magnet assembly 1 forms a reset structure with the side wall 51 of the U-shaped limit groove 5 through the spring 10, and in order to further ensure that the permanent magnet assembly 1 is close to/in contact with the side wall 51 of the U-shaped limit groove, it is preferable to provide a spring storage groove on the supporting plate 132 on the same side as the side wall 51 of the limit groove, as shown in fig. 13. It should be emphasized that the manner for completing the magnetic line cutting between the permanent magnet assembly 1 and the coil 4 by using the switch plectrum 7 specifically provided in the embodiment of the present invention is also applicable to other embodiments of the present invention, and is not described herein again.
