In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

Figure 1 illustrates a schematic diagram of an exploded structure of a wireless control switch. Referring to FIG. 1, the wireless control switch includes a button 1, a self-generating module 2 and a fixing frame 3. Wherein, the self-powered module 2 is installed on the fixed frame 3, the button 1 is covered on the self-powered module 2, the button 1 is used to drive the self-powered module 2 to generate electricity when pressed, and the fixed frame 3 is used for fixed connection with the mounting surface.

Among them, Figure 2 is a top view structure diagram of a three-switch wireless control switch. In combination with Figures 1 and 2, the wireless control switch includes three buttons and three self-generating modules corresponding to the three buttons one-to-one. Each button can drive the corresponding self-generation module to generate electricity separately, so as to realize the individual control of the three controlled devices.

Since the components included in the self-powered module can realize autonomous power generation under the action of external force, when the self-powered module is applied to the wireless control switch, external force can be applied to the button of the wireless control switch to realize autonomous power generation of the wireless control switch and save energy. The cumbersome steps of wiring the wireless control switch. Among them, the self-power generation module can be applied not only to wireless control switches, but also to other devices, such as wireless remote controllers, which are not limited in the embodiment of the present application.

3, the self-power generation module 2 provided by the embodiment of the present application includes: a housing 21, a power generation mechanism 22, a drive arm 23, and an elastic reset member 24; the power generation mechanism 22 is located in the housing 21; the drive arm 23 is pivotally connected On the housing 21 and connected with the power generating mechanism 22, the driving arm 23 is configured to interact with the elastic reset member 24 and cause the power generating mechanism 22 to generate electricity when rotating.

The elastic restoring member 24 is located between the driving arm 23 and the housing 21. In the relaxed state of the elastic restoring member 24, between the first elastic end 241 of the elastic restoring member 24 and the pressing surface of the driving arm 23, and the elastic restoring member A gap is formed between the second elastic end 242 of the 24 and the pressure bearing surface of the housing 21.

In the embodiment of the present application, by providing an interval between the first elastic end 241 and the pressing surface of the driving arm 23, and between the second elastic end 242 and the pressing surface of the housing 21, that is, by making The free length of the elastic reset member 24 is smaller than the distance between the pressure surface of the driving arm 23 and the pressure surface of the housing 21, so that the driving arm 23 is not affected by the reverse elastic force of the elastic reset member 24 in the initial state of being compressed. This effectively reduces the operating force when the drive arm 23 is initially pressed, so that the button of the wireless control switch applying the self-powered module 2 requires a smaller operating force when pressed.

Based on the above description, at least one between the first elastic end 241 of the elastic reset member 24 and the pressing surface of the drive arm 23, and between the second elastic end 242 of the elastic reset member 24 and the pressing surface of the housing 21 There are gaps, and several ways to form the gaps will be introduced separately.

In the first way , referring to FIG. 4, the second elastic end 242 is connected to the pressure surface of the housing 21, and a first interval is formed between the first elastic end 241 and the pressure surface of the driving arm 23.

That is, a first interval is formed between the first elastic end 241 and the pressing surface of the driving arm 23, and there is no interval between the second elastic end 242 and the pressing surface of the housing 21.

Wherein, the interval of the first interval is L0. The second elastic end 242 can be connected to the pressure-bearing surface of the housing 21 by bonding, or it can be directly placed on the pressure-bearing surface of the housing 21 to realize the connection. Of course, the connection can also be realized in other ways. There is no restriction on this.

In this way, in conjunction with Figures 4 and 5, when the drive arm 23 is not pressed, the drive arm 23 is not subject to the reverse elastic force of the elastic reset member 24; when the drive arm 23 is pressed and the rotation stroke is L0, the drive arm 23 The pressing surface is in contact with the first elastic end 241, and then under the blocking of the second elastic end 242 by the pressing surface of the housing 21, the pressing surface of the driving arm 23 begins to compress the elastic reset member 24 until the driving arm 23 is blocked by the second elastic end 242. Press to the limit position. After the driving arm 23 is no longer pressed, the reverse elastic force of the elastic reset member 24 drives the driving arm 23 to move in the reverse direction to return to the initial position, and to ensure that the first elastic end 241 and the pressing surface of the driving arm 23 are re-formed The first interval.

In the second way , referring to FIG. 3, the first elastic end 241 is connected to the pressing surface of the driving arm 23, and a second interval is formed between the second elastic end 242 and the pressing surface of the housing 21.

That is, there is no interval between the first elastic end 241 and the pressing surface of the driving arm 23, and a second interval is formed between the second elastic end 242 and the pressing surface of the housing 21.

Wherein, the interval of the second interval is L0. The first elastic end 241 may be connected to the pressing surface of the driving arm 23 by bonding, or may be connected to the pressing surface of the driving arm 23 by magnetic attraction. Of course, the connection may also be realized in other ways. The example does not limit this.

In this way, in conjunction with Figures 3 and 5, when the drive arm 23 is not pressed, the drive arm 23 is not affected by the reverse elastic force of the elastic reset member 24; when the drive arm 23 is pressed and the rotation stroke is L0, the drive arm 23 drives The second elastic end 242 is in contact with the pressure-bearing surface of the housing 21, and then under the blocking of the second elastic end 242 by the pressure-bearing surface of the housing 21, the pressure surface of the drive arm 23 begins to compress the elastic reset member 24 until The driving arm 23 is pressed to the extreme position. After the driving arm 23 is no longer pressed, the reverse elastic force of the elastic reset member 24 drives the driving arm 23 to move in the reverse direction to return to the initial position, and to ensure that the second elastic end 242 and the pressure-bearing surface of the housing 21 are re-formed The second interval.

In the third way, the side wall of the elastic reset member 24 and the fixing member are movably connected, a first gap is formed between the first elastic end 241 and the pressing surface of the driving arm 23, and at the same time, the second elastic end 242 is connected to the housing A second gap is formed between the pressure-bearing surfaces of 21.

Wherein, the first interval and the second interval can both be L0. Of course, the first interval and the second interval can also be other values, and the first interval and the second interval can be the same, or It can be different.

In this way, when the driving arm 23 is not pressed, the driving arm 23 is not affected by the reverse elastic force of the elastic reset member 24; when the driving arm 23 is pressed and the rotation stroke is the sum of the first interval and the second interval Under the cooperation of the second elastic end 242 blocked by the pressing surface of the housing 21, the pressing surface of the driving arm 23 starts to compress the elastic reset member 24 until the driving arm 23 is pressed to the limit position. After the driving arm 23 is no longer pressed, the reverse elastic force of the elastic reset member 24 drives the driving arm 23 to move in the reverse direction to return to the initial position, and to ensure that the first elastic end 241 and the pressing surface of the driving arm 23 are re-formed In the first interval, a second interval is also formed between the second elastic end 242 and the pressure-bearing surface of the housing 21.

For the third embodiment, the elastic return of the side wall 24 are three ways movable connection, then each of these three ways are described.

Manner 1. With reference to FIGS. 4 and 6, the power generating mechanism 22 may include a magnetic member 221, the fixed member is a magnetic member 221, the magnetic member 221 is located on the first side of the drive arm 23, and the elastic reset member 24 is located on the second side of the drive arm 23 , The first side is opposite to the second side; the side wall of the elastic restoring member 24 abuts against the side wall of the second side of the driving arm 23 through the adsorption between the elastic return member 24 and the magnetic member 221.

Since the side wall of the elastic resetting member 24 abuts against the side wall of the second side of the driving arm 23 by adsorption with the magnetic member 221, that is, the elastic resetting member 24 and the magnetic member 221 are not completely fixed, Thereby, it can be ensured that the elastic reset member 24 moves relative to the driving arm 23 under the action of external force.

In this way, after the driving arm 23 is pressed, the elastic resetting member 24 and the driving arm 23 as a whole move synchronously at the second interval. At this time, the second elastic end 242 of the elastic resetting member 24 is in contact with the pressure-bearing surface of the housing 21 . Later, when the driving arm 23 continues to be pressed, under the blocking action of the second elastic end 242 of the pressure-bearing surface of the housing 21, the elastic reset member 24 and the driving arm 23 slide relatively, and the relative sliding distance is the first interval At this time, the first elastic end 241 of the elastic reset member 24 is in contact with the pressing surface of the driving arm 23. Then when the driving arm 23 continues to be pressed, the pressing surface of the driving arm 23 begins to compress the elastic reset member 24 until the driving arm 23 is pressed to the limit position.

After the driving arm 23 is no longer pressed, the reverse elastic force of the elastic resetting member 24 drives the driving arm 23 to move in the reverse direction to return to the initial position, and at the same time, the elastic resetting member 24 rebounds to act on the pressing surface of the driving arm 23 The reverse force ensures that a first gap is re-formed between the first elastic end 241 and the pressing surface of the driving arm 23, and the magnetic member 221 attracts the side wall of the elastic reset member 24 to hinder the elastic reset member The movement of 24 can ensure that the second elastic end 242 and the pressure-bearing surface of the housing 21 re-form a second interval.

It should be noted that, referring to FIG. 6, the driving arm 23 has a second mounting cavity 232 surrounded by a side wall and a bottom surface on the first side, and the magnetic member 221 is located in the second mounting cavity 232 so as to pass through the second mounting cavity 232. The magnetic member 221 supports. Wherein, the second installation cavity 232 may be a cavity with an opening on one side, or may be a cavity with openings on two adjacent sides.

Further, continuing to refer to FIG. 6, the self-power generation module 2 may further include a gusset 29 that is buckled with the driving arm 23 and encapsulates the magnetic member 221 in the second installation cavity 232. In this way, the magnetic element 221 is enclosed in the second mounting cavity 232 by the buckle 29, which can prevent the magnetic element 221 from being separated from the driving arm 23. Wherein, when the second installation cavity 232 has one side opening, the gusset 29 may have a planar structure, and when the second installation cavity 232 has cavities with adjacent two sides open, the gusset may have an L-shaped structure.

Manner 2, referring to Fig. 7, the fixing member is the side wall of the driving arm 23, and the self-power generation module 2 further includes a first elastic stretching member 25, and the first end of the first elastic stretching member 25 is fixed to the side wall of the driving arm 23 Connected, the second end of the first elastic stretching member 25 is fixedly connected with the side wall of the elastic restoring member 24. Among them, the first elastic stretching member 25 may be a tensile rubber band, of course, it may also be other elastic stretching members and the like.

Since the elastic restoring member 24 and the driving arm 23 are connected by the first elastic stretching member 25, the elastic restoring member 24 can be integrated with the driving arm 23 when the elastic restoring member 24 is not affected by external force. When the elastic restoring member 24 is subjected to an external force, the elastic restoring member 24 can move in a direction close to the pressing surface of the driving arm 23.

In this way, after the driving arm 23 is pressed, the elastic resetting member 24 and the driving arm 23 as a whole move synchronously at the second interval. At this time, the second elastic end 242 of the elastic resetting member 24 is in contact with the pressure-bearing surface of the housing 21 . When the driving arm 23 continues to be pressed, the pressure-bearing surface of the housing 21 supports the second elastic end 242. When the first elastic stretching member 25 begins to contract, the pressing surface of the driving arm 23 is close to the first elastic end 242. When the end 241 moves in the direction and the moving distance is the first interval, the first elastic end 241 is in contact with the pressing surface of the driving arm 23. Then when the driving arm 23 continues to be pressed, the pressing surface of the driving arm 23 begins to compress the elastic reset member 24 until the driving arm 23 is pressed to the limit position.

After the driving arm 23 is no longer pressed, the reverse elastic force of the elastic restoring member 24 drives the driving arm 23 to move in the reverse direction to return to the initial position. At the same time, the elastic restoring member 24 is hoisted by the first elastic stretching member 25, Ensure that the second elastic end 242 and the pressure-bearing surface of the housing 21 re-form a second interval, and the gravity of the elastic restoring member 24 sags to ensure that the first elastic end 241 and the pressure-bearing surface of the drive arm 23 are renewed. Form the first interval.

Manner 3, referring to FIG. 8, the housing 21 has a support frame 211 extending upward on the pressure-bearing surface, and the fixing member is the support frame 211; the self-power generation module 2 further includes a second elastic stretching member 26, a second elastic stretching member The first end of the second elastic stretching member 26 is fixedly connected to the support frame 211, and the second end of the second elastic stretching member 26 is fixedly connected to the side wall of the elastic restoring member 24.

Since the elastic restoring member 24 and the support frame 211 on the housing 21 are elastically connected by the second elastic stretching member 26, when the elastic restoring member 24 is not subjected to external force, the elastic restoring member 24 can be integrated with the housing 21 . When the elastic restoring member 24 receives an external force, the elastic restoring member 24 can stretch the second elastic stretching member 26 to move in a direction close to the pressure-bearing surface of the housing 21.

In this way, after the driving arm 23 is pressed, the driving arm 23 moves at a first interval, and the first elastic end 241 is in contact with the pressing surface of the driving arm 23 at this time. Later, when the driving arm 23 continues to be pressed, the driving arm 23 and the elastic reset member 24 can stretch the second elastic stretching member 26 as a whole, and at the same time move in the direction of the pressure-bearing surface of the housing 21, at the first moving distance At two intervals, the second elastic end 242 is in contact with the pressure-bearing surface of the housing 21. Then when the driving arm 23 continues to be pressed, the pressing surface of the driving arm 23 begins to compress the elastic reset member 24 until the driving arm 23 is pressed to the limit position.

After the driving arm 23 is no longer pressed, the reverse elastic force of the elastic restoring member 24 drives the driving arm 23 to move in the reverse direction to return to the initial position. At the same time, the elastic restoring member 24 is lifted by the second elastic stretching member 26, Ensure that the second elastic end 242 and the pressure-bearing surface of the housing 21 re-form a second interval, and the gravity of the elastic restoring member 24 sags to ensure that the first elastic end 241 and the pressure-bearing surface of the drive arm 23 are renewed. Form the first interval.

It should be noted that for the above three ways of forming at least one space, after the reverse elastic force of the elastic return member 24 drives the driving arm 23 to move in the reverse direction to return to the initial position, in order to realize the positioning of the driving arm 23, In some embodiments, referring to FIG. 5, the self-power generation module further includes a first magnet 27 and a second magnet 28; the first magnet 27 is fixed on the side of the driving arm 23 opposite to the pressing surface, and the second magnet 28 is fixed on On the side of the housing 21 opposite to the pressure-bearing surface; in the relaxed state of the elastic reset member 24, the driving arm 23 abuts against the housing 21 by the adsorption between the first magnet 27 and the second magnet 28. In this way, when the driving arm 23 moves under the elastic force of the elastic reset member 24 to return to the initial position, an attraction force will be generated between the first magnet 27 on the driving arm 23 and the second magnet 28 on the housing 21 Then, the positioning of the driving arm 23 is realized by the attraction force of the second magnet 28 on the first magnet 27.

Of course, in addition to the positioning of the driving arm 23 by the first magnet 27 and the second magnet 28 provided above, the positioning of the driving arm 23 may also be achieved by the magnetic member 221 included in the power generating mechanism 22 described above.

The elastic reset member 24, the housing 21 and the power generating mechanism 22 will be respectively explained in detail below.

Elastic reset part 24

In some embodiments, referring to FIG. 3, FIG. 4 or FIG. 5, the elastic return member 24 may be a compression spring.

In order to ensure that the drive arm 23 has a certain idle stroke when it is pressed, the free length of the compression spring should be less than the maximum distance between the pressure surface of the drive arm 23 and the pressure surface of the housing 21, that is, the drive arm 23 abuts The distance between the pressing surface of the drive arm 23 and the pressing surface of the housing 21 when the upper shell wall of the housing 21 is located. This can reduce the operating force when the drive arm 23 is initially pressed.

For example, the free length of the compression spring may be in the range of 3.5-6 mm. Of course, the free length of the compression spring can also be other values, as long as it can ensure that the driving arm 23 has a certain idle stroke when it is compressed, which is not limited in the embodiment of the present application.

In addition, in order to ensure that after the drive arm 23 is no longer pressed, it can return to the initial position under the action of the reverse elastic force of the compression spring, a compression spring with a larger elastic coefficient can be used to increase the reaction of the compression spring after being compressed. To elasticity. In this way, the driving arm 23 can be urged to return to the initial position under the action of the increased reverse elastic force.

It should be noted that the elastic coefficient can be determined by the pitch of the compression spring, and the elastic coefficient can also be determined by the number of turns of the compression spring. Of course, the elastic coefficient can also be determined by other parameters.

Among them, the greater the pitch of the compression spring and the greater the helix angle, the greater the elastic coefficient. The smaller the number of turns of the compression spring, the greater the elastic coefficient. For example, the number of turns of the compression spring can be any value from 2 to 3.5 turns. For example, the number of turns of the compression spring may be 3 turns.

In other embodiments, referring to FIG. 9, the elastic return member 24 may be a torsion spring. The spring body included in the torsion spring can be sleeved on the pivot shaft between the driving arm 23 and the housing 21, between the first torsion arm included in the torsion spring and the pressing surface of the driving arm 23, and the second torsion spring included A gap is formed in at least one place between the torsion arm and the pressure-receiving surface of the housing 21.

Among them, the torsion angle of the torsion spring in the free state is smaller than the maximum angle between the pressure surface of the drive arm 23 and the pressure surface of the housing 21, that is, the drive arm 23 abuts against the upper shell wall of the housing 21 At this time, the angle between the pressing surface of the driving arm 23 and the pressing surface of the housing 21. This can ensure that there is a gap between the first torsion arm and the pressure surface of the driving arm 23, and between the second torsion arm and the pressure surface of the housing 21, thereby reducing the initial pressure of the driving arm 23. Operating force when pressed.

It should be noted that whether the elastic return member 24 is a compression spring or a torsion spring, referring to FIG. 4, the driving arm 23 has a first mounting cavity 231 surrounded by a pressing surface and a second side wall, and a first elastic end 241 It may be located in the first installation cavity 231. In this way, on the one hand, the installation space of the elastic reset member 24 can be increased, thereby ensuring more selectivity when selecting the elastic reset member 24. On the other hand, the first elastic end 241 is limited in the first installation cavity 231, so as to avoid lateral deviation or bending of the elastic reset member 24 when it is compressed.

Wherein, referring to FIG. 6, when the driving arm 23 has a second mounting cavity 232, compared to the first mounting cavity 231, the second mounting cavity 232 is closer to the pivot end of the driving arm 23. That is, in the direction from the driving end of the driving arm 23 to the pivoting end, the first mounting cavity 231 and the second mounting cavity 232 may be arranged in sequence. Of course, compared to the first mounting cavity 231, the second mounting cavity 232 can also be farther away from the pivot end of the driving arm 23. That is, in the direction from the driving end of the driving arm 23 to the pivoting end, the second mounting cavity 232 and the first mounting cavity 231 may be arranged in sequence.

Shell 21

In some embodiments, the housing 21 may be a structure for accommodating the remaining components included in the self-powered module 2, and is generally made of insulating materials, and its shape and composition may be determined according to actual needs. For example, the power generation mechanism 22, the drive arm 23, and the elastic reset member 24 included in the self-power generation module 2 may all be arranged in the housing 21. Of course, if the self-powered module 2 further includes other components, the other components may also be arranged in the housing 21.

It should be noted that the driving end of the driving arm 23 can extend out of the housing 21 so as to apply a force to the driving end of the driving arm 23 to drive the driving arm 23 to rotate. Of course, the drive arm 23 can also be all arranged in the housing 21. At this time, in order to facilitate the application of force on the drive end of the drive arm 23, a through hole is provided on the shell wall of the housing 21 opposite to the pressure-bearing surface. A force is applied to the driving end of the driving arm 23 through the through hole.

In some embodiments, referring to FIG. 3, FIG. 4 or FIG. 5, when the elastic return member 24 is a compression spring, the housing 21 has a positioning post 214 extending upward from the bottom, and the second elastic end 242 is sleeved on Positioning on the post 214. In this way, the positioning post 214 can position the second elastic end 242 to prevent the compression spring from laterally deviating or bending when compressed by the driving arm 23. Wherein, the positioning pillar 214 may be obtained by extending upward from the area where the pressure bearing surface of the housing 21 is located.

In some embodiments, referring to FIG. 4 or FIG. 5, the housing 21 may include a base 215 and a module cover 216. The module cover 216 is provided separately from the base 215 and can be buckled and fixed with the base 215, and the driving arm 23 can be pivoted. Connected to the base 215.

Wherein, the module cover 216 can be buckled on the base 215 by means of covering. For example, referring to FIG. 10, the module cover 216 may be provided with a buckle 2161, the base 215 is provided with a buckle slot (not shown) that cooperates with the buckle 2161, and the module cover 216 is buckled with the buckle on the base 215 through the buckle 2161 Groove snap-fit connection.

It should be noted that when the housing 21 includes a base 215 and a module cover 216, the pressure-bearing surface of the housing 21 is located on the base 215, and the above-described positioning post 214 may be formed by extending upward from the bottom of the base 215.

It should also be noted that when the housing 21 includes a base 215 and a module cover 216, the base 215, the power generation mechanism 22, the drive arm 23, and the elastic reset member 24 may constitute a power generation component, that is, the self-power generation module 2 may include power generation Component and module cover 216.

Power generation agency 22

In some embodiments, referring to FIG. 3, the power generating mechanism 22 may further include an induction coil 222 and a yoke 223. The induction coil 222 surrounds the core portion of the yoke 223, and one of the magnetic member 221 and the yoke 223 is fixed to the driving arm 23. The other one is fixed in the housing 21.

Wherein, when the driving arm 23 rotates to the first limit position, the magnetic member 221 and the yoke 223 form a first magnetic conductive circuit; when the driving arm 23 rotates to the second limit position opposite to the first limit position, the magnetic member 221 A second magnetic permeable circuit is formed with the yoke 223, and the directions of the magnetic lines of force in the core portion of the first magnetic permeable circuit and the second magnetic permeable circuit are opposite. The first limit position may refer to the initial position when the driving arm 23 is not pressed. The second extreme position may refer to the end position of the driving arm 23 after being pressed.

When the second mounting cavity 232 for accommodating the magnetic element 221 is close to the pivot end of the driving arm 23, the yoke 223 may be closer to the pivot end of the driving arm 23 than the magnetic element 221. That is, in the direction from the driving end of the driving arm 23 to the pivoting end, the magnetic member 221 and the yoke 223 may be arranged in sequence.

Since the magnetic member 221 and the yoke 223 are respectively fixed on the driving arm 23 and the housing 21, when the driving arm 23 is pressed, the driving arm 23 moves relative to the housing 21, thereby realizing the relative movement of the magnetic member 221 and the yoke 223. After that, since the induction coil 222 surrounds the core part of the yoke 223, the magnetic field lines generated by the magnetic element 221 move relative to the induction coil 222 to cut the induction coil 222, thereby causing the induction coil 222 to generate an induced electromotive force, and thereby make the induction coil 222 in the loop Generate induced current to realize the function of self-generation.

In some embodiments, in conjunction with FIG. 4 or FIG. 5, and FIG. 11 and FIG. 12, the yoke 223 may include a first sub-yoke 2231 and a second sub-yoke 2232, and the first sub-yoke 2231 includes a first sub-yoke The iron body 22311 and the first sub core 22312 extending from the first sub yoke body 22311, the second sub yoke 2232 includes a second sub yoke body 22321 and a second sub yoke extending from the second sub yoke body 22321 The iron core 22322, the first sub iron core 22312 and the second sub iron core 22322 constitute the iron core part of the yoke 223.

Wherein, when the driving arm 23 rotates to the first limit position, the magnetic member 221, the first sub-yoke body 22311, the first sub-core 22312 and the second sub-core 22322 form a first magnetic circuit; when the driving arm 23 is rotated to In the second extreme position, the magnetic element 221, the first sub-core 22312, the second sub-core 22322, and the second sub-yoke body 22321 form a second magnetic conductive circuit.

Wherein, the first sub yoke 2231 and the second sub yoke 2232 have the same structure to facilitate common use. For example, referring to FIGS. 11 and 12, the first sub yoke 2231 and the second sub yoke 2232 are both U-shaped.

It should be noted that the end of the magnetic member 221 close to the first sub yoke 2231 is the N pole, and the end of the magnetic member 221 close to the second sub yoke 2232 is the S pole, or the end close to the first sub yoke 2231 is The S pole, and the end close to the second sub-yoke 2232 is the N pole.

In some embodiments, in conjunction with FIGS. 13 and 14, in the case where the housing 21 includes the base 215, the second sub-yoke body 22321 may be provided with a supporting chuck 2233, and the bottom of the base 215 is provided with a supporting chuck 2233 With the mating buckle 2151, the supporting buckle 2233 is buckled with the buckle 2151, so as to realize the fixed connection between the second sub-yoke 2232 and the housing 21.

Wherein, the number of the supporting chuck 2233 and the buckle 2151 corresponds to the setting position, and the number of the supporting chuck 2233 and the buckle 2151 is not limited. When the second sub-yoke 2232 is assembled with the base 215, the supporting yoke 2233 on the second sub-yoke 2232 and the corresponding buckle 2151 on the base 215 are snap-connected, thereby realizing the second sub-yoke 2232 and the base 215 The assembly is simple and convenient.

Since the second sub-yoke 2232 is fastened to the base 215, the first sub-core 22312 and the second sub-core 22322 pass through the induction coil 222 at the same time, so that the second sub-yoke 2232, the induction coil 222, and the first sub-yoke 2231 They are connected to each other as a whole and fixed on the base 215.

In some embodiments, when the yoke 223 includes a first sub-yoke 2231 and a second sub-yoke 2232, when the driving arm 23 is compressed, the driving arm 23 is initially not affected by the elastic reset member when the driving arm 23 is compressed. 24 is hindered by the reverse elastic force, so that the driving arm 23 only needs to overcome the attraction force between the magnetic member 221 and the first sub-yoke 2231. During the resetting process of the driving arm 23, after the elastic restoring member 24 returns to its natural length, the driving arm 23 can continue to return to the initial position under the action of the adsorption force between the magnetic member 221 and the first sub-yoke 2231, and at the same time make The driving arm 23 has no pre-pressure on the elastic reset member 24, so that at least one of the first elastic end 241 and the pressing surface of the driving arm 23, and between the second elastic end 242 and the pressure bearing surface of the housing 21 is formed Space, so as to facilitate the next pressing operation of the driving arm 23.

It should be noted that, referring to FIG. 5, during the pressing process of the driving arm 23, as the driving arm 23 rotates, the gap B between the magnetic member 221 and the first sub-yoke 2231 gradually increases, and the adsorption force drops rapidly. , So that the attraction force between the magnetic element 221 and the first sub-yoke 2231 quickly reduces the obstructive effect of the drive arm 23, thereby reducing the operating force required by the drive arm 23; when the drive arm 23 drives the magnetic element 221 over the first After the intermediate point between the first sub yoke 2231 and the second sub yoke 2232, the adsorption force of the magnetic member 221 and the second sub yoke 2232 is greater than the adsorption force of the magnetic member 221 and the first sub yoke 2231. At this time, the magnetic The attraction force of the piece 221 and the second sub-yoke 2232 serves as the driving force for the rotation of the driving arm 23, thereby further reducing the required operating force of the driving arm 23.

In some embodiments, referring to FIG. 4 or FIG. 5, the magnetic member 221 includes a magnetic steel 2211, a first armature 2212 and a second armature 2213 that are adsorbed on the magnetic steel 2211 and are respectively located on opposite sides of the magnetic steel 2211. Wherein, when the driving arm 23 rotates to the first limit position, the magnetic steel 2211, the first armature 2212, the second armature 2213 and the yoke 223 form a closed first magnetic circuit; when the driving arm 23 rotates to the second limit position At this time, the magnetic steel 2211, the first armature 2212, the second armature 2213 and the yoke 223 form a closed second magnetic conductive circuit.

In this way, when the drive arm 23 is not pressed down, that is, when it is in the first limit position, the magnet 2211 can be adsorbed by the first armature 2212 and the yoke 223, so that the drive arm 23 has no pressure on the elastic reset member 24; When the arm 23 is pressed, the first armature 2212 is separated from the yoke 223. When the driving arm 23 is pressed to the end position, that is, at the second extreme position, the magnet 2211 is adsorbed to the yoke 223 through the second armature 2213 . Since the driving arm 23 can form a closed first magnetic circuit at the first extreme position and a closed second magnetic circuit at the second extreme position, the first magnetic circuit and the second magnetic circuit can be avoided. The occurrence of magnetic flux leakage in the circuit improves the power generation effect of the self-power generation module 2.

Wherein, when the magnetic element 221 is encapsulated in the second mounting cavity 232 of the driving arm 23 by the gusset 29, the second armature 2213 is adsorbed against the bottom of the magnet 2211, and the first armature 2212 is adsorbed against the top of the magnet 2211 , And then the buckle plate 29 is buckled with the driving arm 23 to encapsulate the magnet 2211, the first armature 2212, and the second armature 2213 in the second mounting cavity 232, so that the magnet 2211, the first armature 2212, and the second armature 2213 Stably fixed on the driving arm 23.

It should be noted that the magnetic member 221 may also be directly the magnetic steel 2211, excluding the first armature 2212 and the second armature 2213. In this way, when the driving arm 23 is at the first extreme position or the second extreme position, the magnet 2211 is directly attracted to the yoke 223.

In some embodiments, referring to FIG. 4 or FIG. 5, the power generating mechanism 22 may further include a coil bobbin 224 sleeved on the core part, and the induction coil 222 is wound on the coil bobbin 224. In this way, the coil bobbin 224 sheathed in the core part facilitates the assembly of the induction coil 222, thereby improving the production efficiency of the self-power generation module 2.

In the embodiment of the present application, referring to FIG. 5, when a driving force P is applied to the driving arm 23, the magnetic steel 2211, the first armature 2212 and the second armature 2213 move with the rotation of the driving arm 23. When the driving arm 23 is not pressed, that is, when it is in the first limit position, the first armature 2212 is attracted to the first sub-yoke 2231, and the magnetic line of induction of the magnet 2211 passes through the first armature 2212 and the first sub-yoke in turn The iron body 22311, the first sub-core 22312, the second sub-core 22322, and the second armature 2213 form a first magnetic circuit. In this state, the magnetic field lines in the induction coil 222 are from right to left; under the action of the driving force P When the driving arm 23 continues to rotate to the end position, that is, when it is in the second extreme position, the second armature 2213 is attracted to the second sub-yoke 2232, and the magnetic field lines of the magnet 2211 pass through the first armature 2212 and the first sub-yoke in turn The iron core 22312, the second sub-core 22322, the second sub-yoke body 22321, and the second armature 2213 form a second magnetic circuit. In this state, the magnetic field lines in the induction coil 222 are from left to right. In these two states, the magnetic fields passing through the induction coil 222 have the same magnitude and opposite directions, and an induced electromotive force can be generated in the induction coil 222, thereby generating an induced current in the loop where the induction coil 222 is located. In this way, after the induction current is generated in the loop where the induction coil 222 is located, the controlled device can be controlled to perform corresponding actions (such as controlling the work of a doorbell, a lamp or other loads). After the pressing of the driving arm 23 is cancelled, the driving arm 23 returns to the initial state under the action of the reverse elastic force of the elastic return member 24, and the driving arm 23 is attracted to the first sub-yoke 2231 by the magnetic steel 2211. In the same way, the driving arm 23 can also generate an induced electromotive force and an induced current in the induction coil 222 in the same direction and opposite to the last generated during the reset process.

The embodiment of the present application also provides a wireless control switch, including a button 1, the self-power generation module 2 described above, and a fixing frame 3. The self-power generation module 2 is installed on the fixing frame 3, and the button 1 is covered by the self-power generation module 2. Above, the button 1 is used to drive the driving arm 23 to rotate so that the power generating mechanism 22 generates electricity.

Wherein, the button 1 is pivotally connected to the self-generating module 2 or can be pivotally connected to the fixing frame 3.

Since the drive arm 23 of the self-generation module 2 is not subject to the reverse elastic force of the elastic reset member 24 when it is initially pressed, the initial operating force of the drive arm 23 is effectively reduced. Therefore, the above-mentioned self-power generation is set in the wireless control switch. Module 2 can make the operating force required for pressing the button 1 smaller.

In the related art, since the button 1 of the wireless control switch is usually pivotally connected to the fixing frame 3, when the wireless control switch is installed on the wall, the button 1 needs to be detached from the fixing frame 3 first, and the fixing frame After 3 is fixed to the wall, the button 1 and the fixing frame 3 are reassembled to form a pivot connection, and at the same time, the button 1 and the self-generation module 2 are re-aligned. In this process, the button 1 is cumbersome to disassemble and assemble, which makes it difficult to install the wireless control switch.

The wireless control switch provided by the embodiment of the present application not only reduces the operating force required for pressing the button 1, but also solves the difficulty in installing the wireless control switch due to the complicated disassembly and assembly of the button 1 during the installation of the wireless control switch in the related art. problem.

1 or 15, the button 1 includes an inner button 11 and an outer button 12, the inner button 11 is pivotally connected; the outer button 12 is detachably fixed on the inner button 11, and is covered with a self-powered module 2, wherein When the outer button 12 is pressed, pressure is applied to the inner button 11 to drive the driving arm 23 to rotate through the inner button 11.

In the embodiment of the present application, due to the detachable connection of the inner button 11 and the outer button 12, when the wireless control switch is fixed, the outer button 12 only needs to be detached from the inner button 11, and the fixing frame 3 can be fixed. On the wall, then install the outer button 12 on the inner button 11. There is no need to disassemble the inner button 11, so that there is no need to destroy the assembly relationship of the inner button 11, thus greatly reducing the difficulty of disassembly and assembly, making the installation of the wireless control switch simple and convenient for users to install the wireless control switch. At the same time, since the user does not need to disassemble the inner button 11, the inner button 11 and the self-powered module 2 are assembled stably, which ensures reliable transmission between the inner button 11 and the self-powered module 2, and improves the switching performance.

In some embodiments, the number of self-powered modules 2 corresponds to the number of inner buttons 11, and the number of inner buttons 11 corresponds to the number of outer buttons 12. When the number of outer buttons 12 is one, that is, the wireless control switch is a single-control switch; when the number of outer buttons 12 is two or more, that is, the wireless control switch is a dual-control switch or a multi-control switch.

Among them, the structure of the respective power generation modules 2 may be the same or different. The wireless control switch shown in FIG. 2 is a three-control switch, and the number of outer buttons 12 provided therein is three, the number of inner buttons 11 is three, and the number of self-generation modules 2 is three.

In the embodiment of the present application, when assembling the wireless control switch, the self-powered module 2 can be installed on the fixed frame 3 first, and then the inner button 11 can be pivotally connected to the self-powered module 2 or the fixed frame 3, and then the The outer button 12 is detachably fixed on the inner button 11.

When the self-powered module 2 is installed on the fixed frame, in some embodiments, the self-powered module 2 can be buckled on the fixed frame 3.

By snapping and fixing the self-powered module 2 to the fixed frame 3, the self-powered module 2 can be quickly fixed on the fixed frame 3 without using fasteners, which facilitates the installation of the self-powered module 2; The self-power generation module 2 is removed from the fixing frame 3, which makes the disassembly of the self-power generation module 2 easier and more convenient, and facilitates the replacement of the self-power generation module 2.

For example, referring to Fig. 1, when the housing 21 of the self-powered module 2 includes a base 215, the fixing frame 3 is provided with a clamping block 32, and the clamping block 32 is provided with a clamping hole 321. See Fig. 16, the base 215 is provided with The clamping base 2152 matched with the clamping hole 321 is clamped into the clamping hole 321, so that the self-generation module 2 is fixed on the fixing frame 3. Of course, the fixed installation of the self-generating module 2 and the fixing frame 3 can also be realized in other ways.

It should be noted that when installing the self-powered module 2 on the fixed frame 3, the power generating mechanism 22 included in the self-powered module 2 can be assembled on the base 215 to obtain the power generating component, and then the power generating component can be installed on the fixed frame 3. At this time, the power generation component can be directly installed on the fixing frame 3. Since the power generation components are universal modules, there is no need to distinguish the structure of the power generation components. After all the power generation components of the self-power generation modules 2 are installed in the fixed frame 3, the module cover 216 is then covered with the power generation components, which is beneficial to the standardization of production within the enterprise, thereby improving Productivity. Moreover, since the power generation component is a universal module, the power generation component does not need to be covered with the module cover 216 before being installed in the fixing frame 3, so as to avoid the occurrence of multiple self-power generation modules 2 due to the structural difference of the module cover 216, and there is no need for the self-power generation module 2 Carry out classified management to facilitate the internal production and inventory management of the enterprise, thereby reducing the cost of production management.

Based on the above description, the inner button 11 is pivotally connected to the self-power generation module 2 or the fixing frame 3.

In some embodiments, the inner button 11 is pivotally connected to the self-powered module 2, which not only simplifies the structure of the fixing frame 3, but also ensures that the assembly of the inner button 11 is free from assembly errors of the self-powered module 2 and the fixing frame 3 The influence of the assembly error on the assembly of the inner button 11 is reduced, so that the inner button 11 and the self-power module 2 rotate more stably and reliably, ensure the normal operation of the self-power module 2 and improve the performance of the switch.

Wherein, the inner button 11 is pivotally connected to the housing 21. In this way, the connection between the inner button 11 and the self-generation module 2 can be realized by fixing the inner button 11 and the housing 21.

In this way, the rotation of the through-rotating shaft 111 in the shaft hole 212 realizes the pivotal connection between the inner button 11 and the housing 21.

When the housing 21 includes the module cover 216, one of the module cover 216 and the inner button 11 may be provided with a shaft hole 212, and the other may be provided with a rotating shaft 111 corresponding to the shaft hole 212.

It should be noted that the shaft hole 212 may be provided on the module cover 216, the rotating shaft 111 is provided on the inner button 11, and the inner button 11 is pivotally connected with the shaft hole 212 of the module cover 216 through the rotating shaft 111. In addition, a shaft hole 212 may be provided on the inner button 11, and a rotating shaft 111 may be provided on the module cover 216 to realize the pivotal connection between the inner button 11 and the module cover 216.

In other embodiments, when the inner button 11 is pivotally connected to the fixing frame 3, the connection between the inner button 11 and the fixing frame 3 can be the same as that between the inner button 11 and the self-powered module 2 described above. The connection modes are the same or similar, which is not limited in the embodiment of the present application.

For example, the fixing frame 3 may be provided with a shaft hole, and the inner button 11 is provided with a rotating shaft 111, and the two ends of the rotating shaft 111 respectively enter the shaft holes to realize the pivotal connection between the inner button 11 and the fixing frame 3.

It should be noted that for the above two methods, the inner button 11 needs to be snap-connected with the driving arm 23 to drive the driving arm 23 to rotate when the inner button 11 is pressed, so as to realize the power generation of the self-power module 2.

For example, referring to FIG. 17, the inner button 11 is provided with a connecting post 113, the connecting post 113 is provided with a card slot 1131, and the driving end of the driving arm 23 is locked into the card slot 1131 to realize the connection between the driving arm 23 and the inner button 11. This not only facilitates the connection between the driving arm 23 and the inner button 11, but also prevents the inner button 11 from tilting and shaking left and right during the pressing process, thereby preventing the outer button 12 and the fixing frame 3 from scratching or two adjacent outer buttons 12 There is a linkage phenomenon to improve the performance of the switch.

When the outer button 12 is detachably installed on the inner button 11, in some embodiments, the outer button 12 can be buckled on the inner button 11, so that the outer button 12 can be easily installed on the inner button 11 and the outer button 12 Remove from the inner button 11 to facilitate the installation of the wireless control switch. In addition, the outer button 12 can also be fixed on the inner button 11 in other detachable manners.

In the embodiment of the present application, when the wireless control switch is fixedly installed, referring to FIG. 1 or FIG. 15, the fixing frame 3 has a fixing hole 31, and the housing 21 is provided with a first through hole 213 at a position corresponding to the fixing hole 31, and an inner button 11 is provided with a second via hole 112 at a position corresponding to the first via hole 213, wherein the second via hole 112, the first via hole 213 and the fixing hole 31 can be passed through by a fastener in sequence. In this way, after the fastener is passed through the second via hole 112, the first via hole 213 and the fixing hole 31 in sequence, the installation of the wireless control switch is realized by the fastener.

Among them, the number of fixing holes 31 is two, the two housings 21 near the edge of the fixing frame 3 are respectively provided with first through holes 213 corresponding to the fixing holes 31, and the two inner buttons 11 near the edge of the fixing frame 3 are respectively provided There is a second via 112 corresponding to the first via 213. By providing a first through hole 213 at the position of the housing 21 corresponding to the fixing hole 31, and a second through hole 112 at the position of the inner button 11 corresponding to the first through hole 213, it is not only convenient to install the fasteners, but also convenient Assembly of outer button 12.

It should be noted that the first via 213 provided on the housing 21 may be provided on the module cover 216, and of course, may also be provided on the base 215.

In this state, the magnetic field lines in the induction coil 222 are from right to left When the outer button 12 is pressed, the outer button 12 exerts a driving force on the inner button 11, and the inner button 11 exerts a driving force on the driving arm 23, so that the inner button 11 and the driving arm 23 rotate synchronously. At this time, the magnet 2211 , The first armature 2212 and the second armature 2213 move with the rotation of the driving arm 23 until the driving arm 23 swings down to the limit position, the driving arm 23 compresses the elastic reset member 24, the second armature 2213 and the second sub-yoke 2232 The magnetic field lines of the magnet 2211 pass through the first armature 2212, the core part, the second sub-yoke body 22321 of the second sub-yoke 2232, and the second armature 2213 in turn to form a magnetic circuit. In this state, the induction coil 222 The lines of magnetic force inside are from left to right. Since the driving arm 23 passes through the induction coil 222 in the two states of the same size and opposite directions when it is not under pressure and when it is under pressure, induced electromotive force and induced current can be generated in the induction coil 222. After the induction coil 222 generates electrical energy, the controlled device can be controlled to perform corresponding actions, such as controlling doorbells, lights or other loads. After the outer button 12 is released, the driving arm 23 returns to the initial state under the action of the restoring force of the elastic reset member 24, thereby driving the inner button 11 and the outer button 12 to reset.
