[ 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 is provided with a moving module 11 and a static module 12, the moving module 11 can move relative to the static module 12 to generate induced voltage, the moving module 11 is provided with a power receiving part 111, and a first permanent magnet 112 is arranged on the power receiving part 111;
According to the self-generating switch, the rigid coupling structure of the traditional self-generating switch, which triggers the movement of the movement module 11 by the key, is converted into the permanent magnet structure which is opposite from the same pole and is respectively arranged on the first driving piece 2 and the power receiving part 111, so that a force storage process for pushing magnetic force is formed between the first driving piece 2 and the power receiving part 111 when the self-generating switch device works, the speed of the movement module 11 reaching a movement destination is increased, the time for generating the same magnetic flux variation is reduced, the induced electric quantity is increased, and the reliability and the stability of remote response are ensured.
In the embodiment of the present invention, in consideration of the fact that the proposed self-generating electric switching device needs to be suitable for some applications requiring the reset of the switch key, in combination with embodiment 1 of the present invention, the device further includes a second driving member 3, where the second driving member 3 is disposed on a second side (taking fig. 4 as an example, the first side is the lower side of the power receiving portion 111) opposite to the first side of the power receiving portion 111. For example: the second driving member 3 is a spring or a spring plate. In addition, referring to the manner of generating the driving force by the permanent magnet in embodiment 1, as shown in fig. 7, a third permanent magnet 31 is disposed on the second driving member 3, and the third permanent magnet 31 is disposed opposite to the first permanent magnet 112 in the same polarity. Compared with the implementation mode of using the spring as the second driving member 3, the mode of arranging the third permanent magnet 31 and the first permanent magnet 112 in the opposite manner with the same pole not only reduces the reduction of the mechanical strength of the spring caused by repeated key operation, but also can further avoid the problem of short service life of the spring caused by environmental oxidation and other reasons, because, for the third permanent magnet 31, the anti-oxidation film is additionally plated on the surface of the third permanent magnet, which does not affect the external magnetic force action, and relatively speaking, the anti-oxidation film is additionally plated on the spring, which causes the anti-oxidation film to partially or completely fall off in the repeated deformation process because of the mechanical deformation of the spring.
In order to prevent the power receiving portion 111 from being subjected to the resistance action of the spring or the elastic sheet during the movement process, so as to ensure the effective power generation caused by the fast switching state of the power receiving portion 111, in combination with the embodiment of the present invention, there is also a preferable implementation (especially suitable for the structure of fig. 4 in which the power receiving portion 111 is reset by the spring), as shown in fig. 5 and 6, the first driving member 2 includes a first driving portion 25 and a push rod 26, and the first driving portion 25 is disposed on the first side of the power receiving portion 111; in the initial state, a gap is provided between the first driving portion 25 and the power receiving portion 111; the gap is a distance between the second permanent magnet 21 and the moment when the second permanent magnet 21 can drive the first permanent magnet 112 to drive the power receiving portion 111 to start moving (if fig. 6 shows a critical position from rest to moving of the power receiving portion 111, the change distance of the first driving portion 25 in fig. 5 and 6 is the gap). Thus, the distance of the gap is greater than or equal to the stroke distance of the power receiving portion 111, and in a more specific embodiment, the distance of the gap is greater than or equal to 0.5 millimeters.
The second driving member 3 is disposed at a second side opposite to the first side of the power receiving portion 111, the push rod 26 abuts against the second driving member 3, when the first driving member 2 works, the push rod 22 pushes the second driving member 3 away by the gap distance, and the first driving portion 25 contacts with the power receiving portion 111 and drives the moving module 11 to move relative to the stationary module 12 to generate an induced voltage.
In many implementation manners of the embodiment of the present invention, as for the implementation manner of providing the third permanent magnet 31 on the second driving member 3, not only the manner of fixing the second driving member 3 at the bottom of the housing as shown in fig. 7, but also a driving structure in which the second driving member 3 is movable may be adopted, specifically, as shown in fig. 8, the first driving member 2 and the second driving member 3 are connected by a connecting portion 22, and the corresponding apparatus may further include a return spring 23, and the return spring 23 is connected with the connecting portion 22.
The arrangement of the return spring 23 may be that as shown in fig. 8, the return spring 23 is directly arranged at the bottom of the second driving member 3, or as shown in fig. 9, the assembly composed of the first driving member 2, the first permanent magnet 112, the second driving member 3, the third permanent magnet 31 and the connecting portion 22 is converted into the driving force and the return force by a lever 24 and the return spring 23 by using the lever principle. The mechanism of fig. 9 reduces the mass requirement for the spring compared to fig. 8, while utilizing the principle of leverage to improve the operating characteristics of the spring. In the implementation scheme shown in fig. 9, the gap is represented by not only the distance between the first permanent magnet 112 and the second permanent magnet 21, but also the preset distance between the third permanent magnet 31 and the second permanent magnet 21, where the preset distance satisfies that the power receiving part 111 changes from a static state to a dynamic state after the third permanent magnet 31 moves with the first permanent magnet 112 by the corresponding gap distance, and at this moment, the distance between the third permanent magnet 31 and the second permanent magnet 21 is greater than or equal to the stroke distance of the power receiving part 111.
Based on the above-mentioned technical implementation corresponding to fig. 7, the technique of generating the repulsive restoring force by the opposite homopolar directions between the third permanent magnet 31 and the second permanent magnet 21 can also be applied to the above-mentioned assembly composed of the first driving member 2, the first permanent magnet 112, the second driving member 3, the third permanent magnet 31 and the connecting portion 22, so as to replace the return spring 23 in fig. 9, specifically, as shown in fig. 10, the assembly further includes a fourth permanent magnet 33 and a fifth permanent magnet 32, the fourth permanent magnet 33 is disposed on the connecting portion 22, and the fifth permanent magnet 33 and the fourth permanent magnet 32 are disposed opposite to each other in the homopolar direction.
Based on the idea of using magnetic force to drive the motion module in the power generation assembly proposed by the embodiment of the present invention, an improved solution is also proposed, which has a certain structural difference from the above-mentioned various embodiments, and compared with the idea that the above-mentioned various embodiments are improved from the driving side, in this embodiment, the power receiving part is also improved appropriately, so that the first driving member can be applied to the application scenario of sliding operation, as shown in fig. 11 and fig. 12 (where fig. 11 is an enlarged effect diagram of the dashed-line frame area marked in fig. 12), the first driving member 2 includes a first power driving part 27 and a second power driving part 28, the first power driving part 27 and the second power driving part 28 are fixed by a connecting rod, and the first power driving part 27 and the second power driving part 28 are provided with a second permanent magnet 21 and a sixth permanent magnet 29 in a diagonal manner, the second permanent magnet 21 and the sixth permanent magnet 29 are respectively located obliquely above and directly below the first permanent magnet 112, so that the power receiving part 111 is located at an initial position by a repulsive force generated by the same pole of the sixth permanent magnet 29 in an initial state, and the power receiving part 111 is moved to a target position by the repulsive force generated by the same pole of the second permanent magnet 21 when the second permanent magnet 21 moves to the position directly above the first permanent magnet 112.
On the other hand, based on the idea of using magnetic force to drive the motion module in the power generation assembly proposed by the embodiment of the invention, a structural example that the first driving member can be suitable for sliding operation is also proposed. As shown in fig. 13 and 14 (wherein, fig. 14 is an enlarged effect diagram of a dashed-line frame marked in fig. 13), the power receiving portion 111 further includes a seventh permanent magnet 115, the power receiving portion 111 includes a first power receiving portion 113 and a second power receiving portion 114, and the first power receiving portion 113 and the second power receiving portion 114 are fixed by a connecting rod to form a concave structure; the first permanent magnet 112 and the seventh permanent magnet 115 are respectively arranged on the inner walls of two sides of the concave structure in a staggered manner, and the magnetic poles of the first permanent magnet 112 and the seventh permanent magnet 115 towards the middle of the concave structure are different; the second permanent magnet 21 is driven by the first driving member to move towards the middle magnetic pole surface area of the concave structure of the first permanent magnet 112 and the seventh permanent magnet 115, and the magnetic pole of the second permanent magnet 21 is set to move to the magnetic pole surface area of the first permanent magnet 112 or the seventh permanent magnet 115, so that the same poles repel each other.
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 the embodiment of the present invention, when the self-generating switch is used in a specific application scenario, the self-generating switch generally structurally further includes a signal processing circuit board, and the signal processing circuit board is electrically connected to the output end of the coil.
In embodiment 1 of the present invention, by providing permanent magnet structures with the same poles opposite and respectively disposed on the first driving member and the power receiving portion, a power storage process for pushing magnetic force is formed between the first driving member 2 and the power receiving portion 111 when the self-generating switch device operates, so that the speed at which the moving module 11 reaches the other end is increased, and the time taken for generating the same amount of magnetic flux change is reduced, thereby increasing the amount of induced electricity.
