[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, the terms "inner", "outer", "longitudinal", "lateral", "upper", "lower", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are for convenience only to describe the present invention without requiring the present invention to be necessarily constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
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".
The electromagnetic induction phenomenon is a phenomenon in which induced electromotive force is generated due to a change in magnetic flux, and the most basic formula of the electromagnetic induction law is e-n (d Φ)/(dt), where n is the number of turns of a coil, Δ Φ is the amount of change in magnetic flux, Δ t is the time taken for the change to occur, and e is the generated induced electromotive force.
As can be seen from the formula, if the induced electromotive force (i.e., the induced electric power) is to be increased, it is considered from both the aspect of increasing the amount of change in the magnetic flux and the aspect of time taken to reduce the amount of change in the magnetic flux, and therefore, the following embodiments and other switchable embodiments are considered based on this.
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:
the embodiment of the invention provides a self-generating switch device, which is suitable for various self-generating application scenes, such as a self-generating doorbell switch, a self-generating alarm switch, a self-generating lighting switch and the like, and as shown in fig. 4, the self-generating switch device comprises:
the power generation assembly 1 comprises a motion module 11 and a static module 12, wherein the motion module 11 can move relative to the static module 12 to generate induced voltage, the motion module 11 is provided with a power receiving part 111, and the power receiving part 111 is used for receiving external driving force.
In this embodiment and the following embodiments, in order to further exhibit the significant effects of the structure according to the present invention, it is preferable that the power receiving unit 111 is made of a rigid material that does not deform or store kinetic energy when receiving power. Of course, the power receiving portion 111 may be made of an elastic material as one of the many possible implementations of the embodiment of the present invention.
A first driving member including a first driving part 21 and a push rod 22, wherein the first driving part 21 is disposed on a first side of the power receiving part 111 (taking fig. 4 as an example, the first side is an upper side of the power receiving part 111); in the initial state, a gap is provided between the first driving portion 21 and the power receiving portion 111. Taking fig. 4 as an example, the distance between the lower surface of the first driving portion 21 and the upper surface of the power receiving portion 111 is greater than or equal to the stroke distance of the power receiving portion 111. This is to take into account that, during the driving movement of the power receiving portion 111 by the first driving portion 21, the permanent magnetic attraction acting on the power receiving portion itself may accelerate to separate from the first driving portion 21 and reach the movement destination side, so that the distance defining the gap is greater than or equal to the stroke distance of the power receiving portion 111, and it can be further ensured that the power receiving portion 111 does not contact with the second driving portion 31 during the whole movement, i.e. is not influenced by the external force of the second driving portion 31. In a more specific embodiment, the gap distance is greater than or equal to 0.5 millimeters.
In general, in order to ensure that the first driving portion 21 performs work on the power receiving portion 111 effectively, it is preferable, in combination with the embodiment of the present invention, that the distance of the gap is smaller than the difference between the effective stroke distance of the second driving portion 31 and the stroke distance of the power receiving portion 111, where the effective distance is, for example, when the second driving portion 31 itself is a spring, the effective distance represents the effective deformation distance of the spring. Of course, in the actual process, two distance limiting conditions are preferably implemented such that the distance of the gap is greater than or equal to the stroke distance of the power receiving portion 111.
And a second driving member including a second driving portion 31, wherein the second driving portion 31 is disposed on a second side (for example, fig. 4, the second side is a lower side of the power receiving portion 111) opposite to the first side of the power receiving portion 111, and the push rod 22 abuts against the second driving portion 31. When the first driving member works, the push rod 22 pushes the second driving member away from the gap distance, and the first driving portion 21 contacts the power receiving portion 111 and drives the moving module 11 to move relative to the stationary module 12 to generate an induced voltage.
The embodiment of the invention provides a driving structure with a driving gap, which can be supported by a gap formed by a first driving part, a push rod and a second driving part, so that the first driving part can push the second driving part (such as a spring shown in fig. 4) open first when being pressed by external force, a free movement space is vacated for a power receiving part of a movement module, the movement speed of the movement module is higher during operation, the speed of change of a magnetic induction line in a coil in a self-generating device is further improved, and finally the generated energy is improved.
In combination with the embodiment of the present invention, there is an optional implementation scheme, wherein the second driving portion 31 is specifically a spring or a spring plate. Fig. 4 is a schematic diagram of an implementation scheme using a spring as the second driving portion 31. The implementation mode of using the spring or the elastic sheet as the second driving portion 31 is particularly suitable for application scenarios where the self-generating switch device needs to be reset. As shown in fig. 5, an effect schematic diagram after the first driving portion 21 drives the power receiving portion 111 of the motion module 11 to complete one pressing action is shown, it is easily found from fig. 5 that, in order to enhance stability of an acting force effect of the spring (i.e., the second driving portion 31) on the push rod 22, a diameter of the spring is preferably smaller than or equal to a diameter of the push rod 22, and a motion slot 32 is provided for the push rod 22 and the spring, as shown in fig. 6, which is an enlarged view of a partial region structure, where the motion slot 32 is used to limit deformation of the spring that does not bulge to two sides, and a motion direction of the push rod 22 can be optimized.
In combination with the embodiment of the present invention, there is an optional implementation scheme, wherein when the second driving portion 31 is specifically a torsion spring, the push rod abuts against a middle region of the torsion spring. Fig. 7 is a schematic diagram of an implementation scheme using a torsion spring as the second driving part 31. The implementation of using the torsion spring as the second driving portion 31 is particularly suitable for application scenarios where the self-generating switching device needs to be reset. As shown in fig. 8, an effect diagram of the first driving portion 21 pressing the return arm of the torsion spring to be out of contact with the power receiving portion 111 and reserving a movement space of the power receiving portion 111 is shown, and it can be easily found from fig. 8 that the movement locus of the return arm of the torsion spring and the movement locus of the power receiving portion 111 form a "eight" shape, so that when the torsion spring is used as the second driving portion 31, the overlap distance L between the return arm and the power receiving portion 111 can be adjusted, so that it can be ensured that the power receiving portion 111 does not contact with the torsion spring (i.e. the return arm, the cross bar in the torsion spring shown in fig. 7 that contacts with the power receiving portion 111) in the whole movement process without the gap limitation described in embodiment 1.
In the above-mentioned alternative implementation, an implementation manner is provided in which the second driving portion 31 is specifically a spring or a spring plate, however, there is a technical implementation manner that can be used as an alternative to the above implementation manner, as shown in fig. 9, the first driving member and the second driving portion 31 are integrally formed, and the second driving portion 31 is disposed at the end of the push rod 22. At this time, in order to further enable the integrally formed driving structure to be also suitable for the application occasion of the switch state reset requirement, in combination with this implementation manner, a reset spring 33 or a spring plate may be further configured outside the integrally formed structure, as shown in fig. 9, that is, the second driving member further includes a reset spring 33, the reset spring 33 is connected with the second driving portion 31, and when the driving force is removed, the reset spring 33 drives the second driving portion 31 and drives the first driving member to return to the original state.
In the embodiment of the present invention, two optional configurations are also given to the moving module 11 and the stationary module 12, specifically including:
in the first mode, a permanent magnet assembly is arranged on the moving module 11, and a coil is arranged on the static module 12; the self-generating devices provided by the embodiments of the present invention as shown in fig. 4 to 9 are all implemented by a first method.
In a second mode, the moving module 11 is provided with a coil, and the static module 12 is provided with a permanent magnet assembly. The invention will also be illustrated by the corresponding structure in example 3 which follows.
In the embodiment of the invention, when the self-generating switch is used in a specific application scene, the self-generating switch generally structurally comprises a signal processing circuit board, and the signal processing circuit board is electrically connected with the output end of the coil so as to receive the voltage generated by the induction of the coil and further transmit a signal to the outside. The details of the signal processing circuit board and the coil have been described in the prior art, and are not further described herein.
On the other hand, an improvement idea is provided in the embodiment of the present invention, which can further improve the power generation amount of the self-generating switching device based on the technical solution described in embodiment 1, in a specific improvement structure, the permanent magnet assembly used in the embodiment of the present invention is specifically represented as a permanent magnet assembly 6 as shown in fig. 10, where the permanent magnet assembly 6 includes a first permanent magnet 61 and a second permanent magnet 62, and the same poles of the first permanent magnet 61 and the second permanent magnet 62 are relatively and fixedly arranged; the permanent magnet assembly is coupled with the coil, and the permanent magnet assembly and the coil can move relatively.
When the embodiment of the present invention is implemented in specific applications, the first permanent magnet 61 and the second permanent magnet 62 may be in an annular structure, a bar structure, a cylindrical structure, or the like, but through practical tests, the permanent magnet in the annular structure can bring about an optimal relative fixed arrangement distance, and the fixation is relatively simple, convenient, and stable. The details of which are set forth in the examples that follow.
In the above improved scheme provided for the permanent magnet assembly, through a pair of annular permanent magnets which are oppositely and fixedly arranged in the same pole and a coil coupled with the annular permanent magnets, the magnetic flux change rate of the coil during induction is improved through the change of the relative positions of the coil and the annular permanent magnets, so that the power generation power of the self-generating switch is improved, and the reliability and the stability of remote response are ensured.
In the embodiment of the present invention, the coupling manner of the permanent magnet assembly 6 and the coil 4 at least includes the following:
the first coupling mode:
the permanent magnet assembly 6 is directly inserted into the winding area of the coil 4, as shown in fig. 10, which is a schematic structural diagram of the coupling manner. As shown in fig. 11, 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 6, so that the permanent magnet assembly 6 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 6 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. 12, 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 6 with the U-shaped limiting groove 5 in the movement process, so that the generated power is improved.
Example 2:
based on the first coupling manner between the permanent magnet assembly 6 and the coil 4 as set forth in embodiment 1, a possible implementation scheme is provided for further solving the problem that the position of the permanent magnet assembly 6 relative to the coil 4 is changed and the homopolar fixed arrangement of the first permanent magnet 61 and the second permanent magnet 62 is adopted in embodiment 1, so as to further improve the power generation capacity by the structure including the gap as set forth in embodiment 1. As shown in fig. 10 and 11, the permanent magnet assembly 6 further includes a permanent magnet fixing member 63 besides the first permanent magnet 61 and the second permanent magnet 62, where the permanent magnet fixing member 63 is used to complete the homopolar opposite fixing arrangement of the first permanent magnet 61 and the second permanent magnet 62, specifically:
the first permanent magnet 61 and the second permanent magnet 62 are oppositely arranged in the same pole; the connecting rod 631 of the permanent magnet fixing member 63 passes through the hollow area of the first permanent magnet 61 and the hollow area of the second permanent magnet 62, and the support plates 632 of the permanent magnet fixing member 63 are disposed at both ends of the connecting rod 631, so that the first permanent magnet 61 and the second permanent magnet 62 are fixed in a homopolar manner.
The connecting rod 631 and the supporting plate 632 are preferably fixed by screws, that is, both ends of the connecting rod 631 are provided with screw holes, and the supporting plate 632 is provided with through holes corresponding to the screw holes, and the fixing of the connecting rod 631 and the supporting plate 632 is completed by screws; and, the one side support plate 632 and the connecting rod 631 can be integrally formed/welded in advance, and the other side support plate can be fixed with the connecting rod 631 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 61 and the second permanent magnet 62, and when the relative position of the joint of the coil 4 and the first permanent magnet 61 and the second permanent magnet 62 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 61 and the second permanent magnet 62 and consider a situation that a large amount of power generation needs to be generated, the magnetic strength of the first permanent magnet 61 and the second permanent magnet 62 needs to be selected to be large, at this time, it is preferable to add a spacer 64 (as shown in fig. 11) at a position where the same poles of the first permanent magnet 61 and the second permanent magnet 62 are spliced together in opposite directions, where the spacer 64 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. 13, a schematic diagram of the magnetic induction lines after the first permanent magnet 61 and the second permanent magnet 62 are arranged with the same poles facing each other (in which, for example, the first permanent magnet 61 and the second permanent magnet 62 are arranged with the same poles facing each other), and the effects are explained by the movement states of the self-generating electric switching device shown in fig. 14 and 15. The moving mode of the connection position of the first permanent magnet 61 and the second permanent magnet 62 relative to the coil 4 at least includes the following modes:
the first movement mode is to move from the middle to the left, for example, from the state of fig. 11 to the state of fig. 14;
the second movement mode is a movement from the middle to the right, for example, from the state of fig. 11 to the state of fig. 15;
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 6 to move back and forth is poked back and forth.
The moving mode three, moving from left to right, for example, changing from the state of fig. 14 to the state of fig. 15;
the fourth movement mode is a movement from the right side to the left side, and changes from the state of fig. 15 to the state of fig. 14, for example.
The common characteristic of the above-mentioned moving modes is that the connection point of the first permanent magnet 61 and the second permanent magnet 62 has a certain displacement in the area of the width covered by the coil 4. As can be seen from fig. 13, the direction of the magnetic induction line at the connection point of the first permanent magnet 61 and the second permanent magnet 62 is rotated by 180 °, so that compared with the change of the magnetic flux relative to the coil 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. 11, the device further includes a U-shaped limiting groove 5, specifically:
the first assembly composed of the first permanent magnet 61, the second permanent magnet 62 and the permanent magnet fixing piece 63 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. 10 and referring to the working state of the self-generating switch device shown in fig. 14 and 15, the U-shaped limiting groove 5 is made of a magnetic material, and under the action of toggling or pressing, the permanent magnet assembly 6 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. 11, and the target position is shown in fig. 14 or 15), 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 6 shown in fig. 13 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 6 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.
The permanent magnet assembly and the related limiting groove structure thereof proposed by the embodiment of the present invention are applied to the self-generating switch device described in embodiment 1, and the structural cross-sectional view thereof is shown in fig. 16, wherein the first driving member (including the first driving portion 21 and the push rod 22 shown in fig. 16) and the second driving portion 31 are integrally formed to form a groove shifting piece structure. The gap provided between the first driving part 21 and the power receiving part 111 in embodiment 1 is embodied as a gap provided between the first driving part 21 and the supporting plate 632 in fig. 16, that is, the function of the power receiving part 111 in embodiment 1 is embodied as being realized by the supporting plate 632 in embodiment of the present invention, and compared with the case that the power receiving part 111 shown in fig. 4 is a single component, the supporting plates 632 in embodiment of the present invention are provided in pairs on both sides of the permanent magnet assembly 6. As shown in fig. 17, the effect of the permanent magnet assembly 6 sliding horizontally to the right is schematically shown in the figure, in which the first driving portion 21 drives the left supporting plate 632 under the pushing of the external force. Compared with embodiment 1, the embodiment of the present invention can not only obtain the effect of increasing the initial speed of the first driving portion 21 when contacting with the supporting plate 632 in embodiment 1, thereby increasing the moving speed of the permanent magnet assembly 6 in the coil 4, and finally increasing the power generation amount; on the other hand, the amount of change in the magnetic flux in the coil 4 can also be improved based on the magnetic induction line characteristics of the permanent magnet assembly 6 itself provided with the same poles facing each other as proposed in the embodiment of the present invention. On the other hand, as shown in fig. 17, when the permanent magnet assembly 6 is pushed to the right, the gap shifts, and when the permanent magnet assembly 6 returns from fig. 17 to fig. 16 under the action of the spring, the gap between the second driving part 31 and the right supporting plate 632 in fig. 17 increases the initial speed of the second driving part 31 contacting the right supporting plate 632, so that the moving speed of the permanent magnet assembly 6 relative to the coil 4 in the returning process can be further increased, and the final power generation amount can be increased, which is also the effect in the structure shown in fig. 9. In addition, based on the structural description of the operation modes shown in fig. 16 and 17, the corresponding structure can be applied to other moving mode structures proposed by the present invention, and will not be described herein again.
Example 3:
the embodiment of the present invention is based on the second coupling manner between the permanent magnet assembly 6 and the coil 4 proposed in embodiment 1, and further provides a feasible implementation scheme for the position change of the permanent magnet assembly 6 relative to the coil 4 and the relative fixed arrangement of the same poles of the first permanent magnet 61 and the second permanent magnet 62 in embodiment 1. As shown in fig. 12, in the embodiment of the present invention:
the coil 4 is arranged on the outer ring of the die 41 with two through holes, wherein the first through hole 411 of the die 41 is used for passing through the first permanent magnet 61 and the second permanent magnet 62 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 6 and the U-shaped limiting groove 5 may adopt a combined structure (as shown in fig. 12) 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 6 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. 12) and that of the embodiment 2 (shown in fig. 10) is that: the U-shaped limiting groove 5 and the permanent magnet assembly 6 are nested in the annular structure formed by the coil 4, so that the permanent magnet assembly 6 is shifted to generate displacement relative to the coil 4, and particularly when one end of the permanent magnet assembly 6 is contacted with one side wall of the U-shaped limiting groove 5, the permanent magnet assembly 6 changes the magnetic line density of the U-shaped limiting groove 5, the change strength of the magnetic flux in the coil 4 is further improved, and the self-generating capacity is enhanced. Further, considering that the supporting plate 632 is disposed between the permanent magnet assembly 6 and the U-shaped retaining groove 5, in order to increase the influence of the permanent magnet assembly 6 on the magnetic flux density of the U-shaped retaining groove 5 when reaching the target position (as shown in fig. 14 or fig. 15, that is, the supporting plate 632 contacts with the inner wall of the U-shaped retaining groove 5), it is preferable that the supporting plate 632 is made of a magnetizable metal material. However, the support plate 632 may be made of a plastic material having elasticity in order to reduce noise caused by the switching operation.
As an alternative implementation scheme for driving the permanent magnet assembly 6 to move, in addition to the toggle permanent magnet assembly 6 shown in fig. 16 in embodiment 2 for realizing the mutual movement between the permanent magnet assembly 6 and the coil 4 (i.e. the moving module 11 can move relative to the stationary module 12 in embodiment 1), the embodiment of the present invention further provides a method for realizing the mutual movement between the permanent magnet assembly 6 and the coil 4 by toggling the coil 4, as shown in fig. 18, at this time, the supporting plate 632 of the permanent magnet assembly 6 does not need to extend as shown in fig. 16, but only needs to be matched with the outer diameter of the permanent magnet assembly radially. In the driving manner shown in fig. 18, the first driving member (including the first driving portion 21 and the push rod 22 shown in fig. 16) and the second driving portion 31 are preferably integrally formed to form a groove paddle structure; the second driving member further comprises a spring 33 and is connected to the housing to provide a return force to the second driving portion 31. In this case, in comparison with the embodiment of example 2 in which the support plate 632 is used as the embodiment 111 proposed in example 1, in this embodiment, both the left and right side walls of the coil 4 are used as the embodiment of the power receiving unit 111 in example 1, as shown in fig. 18. Compared with the mode of shifting the permanent magnet assembly 6 to realize the relative motion of the permanent magnet assembly 6 and the coil 4 in the embodiment 2, the mode of shifting the permanent magnet assembly 6 to realize the relative motion of the permanent magnet assembly 6 and the coil 4 provided by the embodiment of the invention can further effectively utilize the length resource of the permanent magnet assembly 6 which is oppositely arranged in the same pole, thereby further reducing the volume of the device under the condition of ensuring that the difference of the output power is not large.
It should be noted that fig. 16 and 18 only show two of the ways of accomplishing the coupling between the switch plectrum (i.e. the combination structure formed by the first driving portion 21, the push rod 22 and the second driving portion 31, also referred to as the groove plectrum in the embodiment of the present invention) and the permanent magnet assembly 6, and based on a common inventive concept, the related extended implementation scheme and the preferred implementation scheme applied in any of the above embodiments, and the new improved scheme obtained by the related technical content applicable to other embodiments of the present invention without creative efforts through proper derivation also belong to the protection scope of the embodiments of the present invention, and therefore, the detailed description is not repeated herein.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
