[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0034] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0035] like Figures 1 - 2 As shown, the utility model provides a novel self-generating switch, comprising: a bottom cover 1 and a surface cover 2 connected to each other, the bottom cover 1 is provided with a bracket 4 for mounting a power generation module 3, a pressure plate 5 is movably provided between the bracket 4 and the bottom cover 1, one end of the pressure plate 5 is a pressure-bearing end 510, and the other end is a transmission end 520, the pressure-bearing end 510 is directly or indirectly connected to the pressing side of the surface cover 2, the transmission end 520 is connected to the driving part 310 of the power generation module 3, and the transmission end 520 is arranged on the side of the power generation module 3 away from its driving part 310; the force arm of the pressure-bearing end 510 is greater than the force arm of the transmission end 520.

[0036] The power generation module 3 may be any power generation device having a driving part 310 (ie, a spring) in the prior art.

[0037] The power generation module 3 is fixed to the bracket 4 by snapping or any other method. After the power generation module 3 and the bracket 4 are installed, the bracket 4 and the bottom cover 1 are fixed, so that a gap is formed between the power generation module 3 and the bottom surface of the bottom cover 1 without contact, thereby reducing the vibration of the power generation module 3 when it is in action and directly transmitting it to the bottom cover 1, thereby reducing noise;

[0038] The pressing side of the cover 2, i.e. Figure 1 As shown in the figure, the side of the cover 2 is tilted up, and when the pressing side of the cover 2 is pressed by hand, the pressed end 510 of the pressing plate 5 is forced to move downward ( Figure 1 As shown below), the transmission end 520 moves upward ( Figure 1 As shown above, it acts on the driving part 310, and the driving part 310 is activated to make the power generation module 3 generate electric energy; because the pressure end 510 and the transmission end 520 of the pressure plate 5 are respectively located on both sides of the power generation module 3, and the force arm of the pressure end 510 is greater than the force arm of the transmission end 520, a force-saving lever is formed, thereby reducing the triggering force of the power generation module 3, that is, when a smaller force is applied to the surface cover 2, the power generation module 3 can generate electricity.

[0039] Through the above structural design, the power generation module 3 is installed on the bracket 4, so that the power generation module 3 is not directly fixed to the bottom cover 1, which can reduce noise and is convenient to install; by making the force arm of the pressure-receiving end 510 of the pressure plate 5 greater than the force arm of the transmission end 520, the triggering force of the power generation module 3 can be reduced, making it more labor-saving to press the face cover 2 and convenient to use.

[0040] As Figure 3 and Figure 4 shown, in one embodiment, the bracket 4 is provided with a receiving area A410 for installing the power generation module 3 and a receiving area B420 for installing the reset member 6. The reset member 6 is connected to the driving portion 310 of the power generation module 3, and the transmission end 520 of the pressure plate 5 and the reset member 6 are respectively located on both sides of the driving portion 310.

[0041] The power generation module 3 is limit-mounted in the receiving area A410 of the bracket 4. The reset member 6 is selected as a torsion spring. Two mounting posts are provided at the receiving area B420. The torsion spring is sleeved on the mounting posts, and then one end of the torsion spring abuts against the driving portion 310, and the other end abuts against the top surface of the receiving area B420 of the bracket 4. After the acting force on the pressure plate 5 is removed, under the action of the torsion spring, the driving portion 310 can be pushed to move, thereby pushing the transmission end 520 to return to the initial position (i.e., the pressure-receiving end 510 is lifted); through the provided bracket 4, the installation and fixation of the reset member 6 and the power generation module 3 can be facilitated.

[0042] As Figure 1 、 Figure 3 and Figure 5 shown, further, the power generation module 3 is limit-set in the receiving area A410; connecting blocks 430 are provided on two opposite inner side walls of the receiving area A410, and slots 431 are formed on the connecting blocks 430. Corresponding insertion blocks 320 are formed on the power generation module 3.

[0043] The connecting block 430 is arranged close to the receiving area B420. During installation, the power generation module 3 is inserted from the side of the receiving area A410 away from the receiving area B420, so that the insertion block 320 is inserted into the slot 431.

[0044] Further, an elastic layer can be provided on the side wall of the receiving area A410 so that the power generation module 3 can be limited in the receiving area A410; alternatively, an elastic pad can be provided at the gap between the bottom cover 1 and the power generation module 3, and the elastic pad is connected to the bottom cover 1; the above design can ensure that the power generation module 3 is firmly installed.

[0045] As Figures 6 - 8As shown, in one embodiment, arc-shaped protrusions A440 are respectively provided on both sides of the bracket 4. The arc-shaped protrusions A440 protrude towards the side of the bottom cover 1. An arc-shaped protrusion B110 corresponding to the arc-shaped protrusion A440 is provided on the bottom cover 1. The arc-shaped protrusions A440 and the arc-shaped protrusion B110 are respectively in contact with two sides of the pressing plate 5.

[0046] Furthermore, two limiting blocks A120 corresponding to the two arc-shaped protrusions A are also provided on the bottom cover 1. A limiting space 7 is formed between the two limiting blocks A120 and the arc-shaped protrusion A440. A hollowed-out area 530 is provided on the pressing plate 5. A limiting block B531 placed in the limiting space 7 is provided inside the hollowed-out area 530.

[0047] The limiting block B531 of the pressing plate 5 is placed in the limiting space 7 to limit the movement of the pressing plate 5. When the pressing plate 5 is stressed and moves, the arc-shaped protrusion A440 serves as the upper fulcrum of the pressing plate 5, and the arc-shaped protrusion B110 serves as the lower fulcrum of the pressing plate 5 to support the movement of the pressing plate 5.

[0048] Part of the bracket 4 can pass through the hollowed-out area 530. The transmission end 520 of the pressing plate 5 passes through the accommodating area B420 of the bracket 4 and contacts the driving part 310. With such a setting, the installation space can be saved.

[0049] As Figure 3 and Figure 9 As shown, in one embodiment, a plurality of mounting holes A450 are provided on the bracket 4. A screw cylinder A130 corresponding to the mounting hole A450 is provided on the bottom cover 1. At least one mounting hole A450 is arranged in the accommodating area B420. Limiting blocks C460 are respectively provided on two outer side walls of the bracket 4 close to the accommodating area B420. A limiting block D140 corresponding to the limiting block C460 is provided on the bottom cover 1. A limiting groove 141 is provided on the limiting block D140. The limiting groove 141 is used to limit the movement of the limiting block C460 in the axial direction of the screw cylinder A130.

[0050] The bracket 4 and the bottom cover 1 are fixed by screwing a screw through the mounting hole A450 and then threadedly connecting with the screw cylinder A130. Since the accommodating area B420 of the bracket 4 is affected by the resetting member 6, in order to ensure the stability of the bracket 4, the limiting block C460 is placed in the limiting groove 141 of the limiting block D140, so as to prevent the end of the bracket 4 close to the accommodating area B420 from shaking or tilting after being stressed through the limiting groove 141 and the limiting block C460, ensure the stability of the connection, reduce the shaking of the bracket 4, and thus reduce the noise.

[0051] As Figure 10 and Figure 11As shown, in one embodiment, it further includes: a waterproof layer 8 covering the outer side of the pressing plate 5, the bracket 4 and the power generation module 3, the bottom cover 1 is provided with an annular groove 150, and the waterproof layer 8 is fixed at the annular groove 150 through a waterproof cover 9;

[0052] Among them, the waterproof cover 9 is hollowed out at the corresponding positions of the bracket 4 and the pressure plate 5, so that the surface cover 2 can indirectly contact the pressure plate 5, that is, the surface cover 2 contacts the waterproof layer 8, and the waterproof layer 8 fits tightly with the pressure end 510 of the pressure plate 5, which is made of flexible material.

[0053] Furthermore, a circuit board 10 for realizing the corresponding functions of the self-generating switch is also provided in the bottom cover 1 , and a waterproof layer 8 is also provided on the outside of the circuit board 10 .

[0054] Furthermore, the waterproof cover 9 is provided with a plurality of mounting holes B910, and the bottom cover 1 is provided with screw barrels B160 corresponding to the mounting holes B910.

[0055] The lower edge of the waterproof layer 8 can be placed in the annular groove 150. The waterproof layer 8 is made of silicone material and can fit tightly with the pressure plate 5, the bracket 4 and the power generation module 3. After the waterproof layer 8 is installed, the waterproof cover 9 is buckled on the outside of the waterproof layer 8. The lower edge of the waterproof cover 9 can also be placed in the annular groove 150 and is in close contact with the waterproof layer 8. Then, a screw is used to pass through the installation hole B910 and then threadedly connected with the screw barrel B160 to fix the waterproof layer 8 and the waterproof cover 9.

[0056] like Figure 1 As shown, further, a pressing protrusion 210 is provided on one side of the surface cover 2 close to the bottom cover 1 , and the pressing protrusion 210 directly or indirectly contacts the pressed end 510 of the pressing plate 5 .

[0057] After the pressing side of the cover 2 is subjected to force, the pressing protrusion 210 can generate a force on the pressed end 510 of the pressing plate 5, thereby causing the pressing plate 5 to move.

[0058] like Figure 1 As shown, further, a side of the surface cover 2 close to the transmission end 520 of the pressure plate 5 is a fixed side, and the fixed side of the surface cover 2 is hinged to the bottom cover 1 .

[0059] The raised side of the cover 2 is the pressing side, and the other opposite end is the fixed side. The lower part of the fixed side is hinged to the bottom cover 1. When the pressing side is subjected to force, the hinge between the cover 2 and the bottom cover 1 rotates relatively.

[0060] In one embodiment, the number of the face covers 2 is one or more.

[0061] like Figures 12 - 14As shown, structural diagrams are shown with the number of face covers 2 being one, two, and three respectively. The number of face covers 2 can be set according to the functional requirements of the self - generating switch, and is not limited to the number shown in the figure.
