[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0055] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0056] In the following description, the terms "first," "second," and "..." are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0057] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. The term "connection," unless otherwise specified, includes both direct and indirect connections.

[0058] In some specific embodiments, the self-generating switch can be used to control the state of any electrical appliance. For example, it can be used to control the on / off state of a light bulb; it can also be used to control the operating state of a smart toilet, such as controlling the state of the toilet seat, the toilet lid, and the flushing function. For ease of explanation, the following description uses the example of the self-generating switch controlling the operating state of a smart toilet to illustrate the specific structure of the self-generating switch.

[0059] In some embodiments, such as Figure 1As shown, the self-generating switch 1 includes: a housing 10, a button 20, a trigger 30, a reset structure 40, and a power generation component 50. The button 20 is connected to the housing 10 and extends along a first direction. Optionally, the button 20 is fixedly connected to the housing 10, and at least a portion of the button 20 can be displaced under pressure; alternatively, the button 20 is movably connected to the housing 10, and the button 20 can move relative to the housing 10 under pressure. The trigger 30 is connected to the housing 10 and is located below the button 20. It can be understood that when the self-generating switch 1 is in a horizontal position, the trigger 30 is located below the button 20. For ease of explanation, the following descriptions of the relative positions of the components or structures of the self-generating switch 1 are all performed with the self-generating switch 1 in a horizontal position. Meanwhile, the trigger 30 has a linkage part 31 that can be actuated by the button 20. That is, by pressing, the button 20 moves relative to the housing 10 or at least a part of the button is displaced, allowing the button 20 to directly or indirectly apply a force to the trigger 30, thereby causing the linkage part 31 of the trigger 30 to move relative to the housing 10. In other words, the force can move the linkage part 31 from a first position to a second position. Optionally, the trigger 30 is fixedly connected to the housing 10, and the trigger 30 can be displaced under the force applied by the button 20 to move the linkage part 31 from the first position to the second position; alternatively, the trigger 30 is movably connected to the housing 10, and the trigger 30 can move relative to the housing 10 under the force applied by the button 20 to move the linkage part 31 from the first position to the second position.

[0060] The reset structure 40 is located below the button 20 and can reset the button 20. That is, after the pressure applied to the button 20 is removed, the reset structure 40 can apply a reset force to the button 20 to return it to the state before the pressure was applied. When the button 20 is fixedly connected to the housing 10 and the pressure applied to the button 20 can cause the button 20 to move, the reset structure 40 can return the button 20 to its shape before the pressure was applied after the pressure is removed. When the button 20 is movably connected to the housing 10 and the pressure applied to the button 20 causes the button 20 to move relative to the housing 10, the reset structure 40 can return the button 20 to its position before the pressure was applied after the pressure is removed. Optionally, the reset structure 40 can also reset the trigger 30. That is, after the pressing pressure applied to the button 20 is removed, the force applied by the button 20 to the trigger 30 is also removed. At this time, the reset structure 40 can apply a reset force to the trigger 30 so that the linkage part 31 of the trigger 30 returns from the second position to the first position. At the same time, during the process of the linkage part 31 of the trigger 30 returning from the second position to the first position, the linkage part 31 applies a reset force to the button 20 to achieve the reset of the button 20.

[0061] The power generation component 50 can be triggered by the trigger 30 to generate electrical energy. The power generation component 50 can be any structure that can generate electrical energy when triggered by the trigger 30. For example, the power generation component 50 can be a piezoelectric structure made of piezoelectric material. When the button 20 is pressed, the pressing force applied to the button 20 can be transmitted to the piezoelectric structure through the trigger 30, thereby generating electrical energy in the piezoelectric structure. For example, the power generation component 50 can be an electromagnetic power generation structure that generates electrical energy by cutting magnetic field lines with a magnet under the trigger of the trigger 30 and through the principle of electromagnetic induction. For example, when the linkage 31 moves from the first position to the second position and / or from the second position to the first position, the linkage 31 can trigger the magnet in the power generation component 50 to cut magnetic field lines and generate electrical energy through the principle of electromagnetic induction.

[0062] The button 20 includes a pressable pressing part 21. When the pressing part 21 is pressed, it can activate the linkage part 31, thereby triggering the power generation component 50 to generate electrical energy. By pressing the pressing part 21 of the button 20, the linkage part 31 can be activated to move from a first position to a second position, thereby triggering the power generation component 50 to generate electrical energy. It can be understood that the self-generating switch 1 can convert the kinetic energy generated when the button 20 is pressed into electrical energy, so that the self-generating switch 1 can consume the electrical energy to achieve the required function. For example, the self-generating switch 1 has a signal output component for outputting control signals, which can consume the electrical energy to output control signals for controlling the state of electrical appliances; for example, the self-generating switch 1 has a status indicator light, which can consume the electrical energy to output light signals that can indicate the state of the self-generating switch 1.

[0063] This invention provides a self-generating switch, comprising a housing, a button connected to the housing and extending along a first direction, a trigger member connected to the housing and located below the button, a reset structure located below the button to reset the button, and a power generation component that can be triggered by the trigger member to generate electrical energy. The trigger member has a linkage portion that can be actuated by the button, and the button includes a pressable portion. When the pressable portion is pressed, it actuates the linkage portion, thereby triggering the power generation component to generate electrical energy. By providing a trigger member that can be actuated by the pressable portion of the button, the linkage portion of the trigger member can trigger the power generation component to generate electrical energy when the pressable portion of the button is pressed. This converts the kinetic energy of pressing the button's pressable portion into electrical energy generated by the power generation component, enabling the self-generating switch to achieve the required function without the need for power supply components such as batteries. Furthermore, this self-generating switch has an ingenious structural design.

[0064] In some embodiments, such as Figure 2 As shown, in the first direction (the first direction is as follows) Figure 2 (As shown by the middle arrow) Button 20 has a first end 22 and a second end 23. Pressing part 21 extends from the first end 22 to the second end 23. That is, a double-sided pressing structure is formed between button 20 and housing 10. It can be understood that along the first direction, button 20 has a first end 22 and a second end 23 opposite to each other, and the area between the first end 22 and the second end 23 of button 20 is set as pressing part 21. Pressing the area between the first end 22 and the second end 23 of button 20 can cause button 20 to touch the linkage part 31 of trigger member 30, thereby triggering the power generation component 50 to generate electrical energy.

[0065] Meanwhile, in the first direction, the linkage part 31 is located in the middle of the bottom of the button 20, so that the linkage part 31 can be activated when the pressing part 21 between the first end 22 and the second end 23 of the button 20 is pressed. That is, the linkage part 31 is set between the first end 22 and the second end 23 of the button 20 in the first direction, so that the button 20 can be pressed on both sides with only one trigger 30. Compared with the scheme of setting the linkage part at the two ends of the button 20, the structure is more compact and the structure of the self-generating switch is further simplified. It should be noted that the specific position of the linkage part 31 between the first end 22 and the second end 23 below the button 20 can be any position where the button 20 can be pressed on both sides by a single linkage part 31. Furthermore, the specific position of the linkage part 31 varies depending on the connection method between the button 20 and the housing 10. For example, if the button 20 and the housing 10 are movably connected, and the button 20 moves downwards when the pressing part 21 is pressed, the button 20 can be positioned anywhere between the first end 22 and the second end 23 below the button 20 to enable the button 20 to press on both sides. Alternatively, if the button 20 and the housing 10 are rotatable... A rotatable connection is used to allow button 20 to rotate relative to housing 10 around a preset rotation axis, wherein the rotation axis is perpendicular to a first direction and located between the first end 22 and the second end 23. A linkage part 31 is positioned at the center below button 20 and extends from one side of the rotation axis to the other side in the first direction. This ensures that when pressure is applied to any pressing part between the first end 22 and the second end 23, button 20 will be activated during its rotation around the rotation axis, thereby triggering the power generation component 50 to generate electrical energy. In other words, the button 20 achieves a dual-sided pressing function. For ease of explanation, the following description uses the rotatable connection between button 20 and housing 10 as an example to illustrate the structure of the self-generating switch 1. The linkage part 31 being located below button 20 can be understood as being located at any position between the first end 22 and the second end 23 that can be activated by the button, not just the center position below button 20.

[0066] In some embodiments, such as Figure 3 As shown, the button 20 includes a button body 24 and a contact portion 25. The button body 24 has a pressing portion 21 disposed on the upper surface of the button body. That is, the button body 24 extends along a first direction and has a first end 22 and a second end 23 opposite to each other along the first direction. The pressing portion 21 is located above the button body 24. The contact portion 25 is located below the button body 24 and is activatable. Figure 2The linkage part 31, i.e., the abutting part 25, extends downward from the lower surface of the button body 24 to reduce the distance between the abutting part 25 and the linkage part 31. This allows the button 20 to reliably actuate the linkage part 31 without increasing the thickness of the button body 24. At the same time, the button 20 applies force to the linkage part 31 through the abutting part 25, which has a larger thickness. That is, the part of the button 20 with greater structural strength bears the reaction force applied to the button 20 by the linkage part 31, thereby improving the service life of the button 20.

[0067] In some embodiments, such as Figure 4 As shown, the abutment portion 25 includes a first sub-abutment portion 251 and a second sub-abutment portion 252. The first sub-abutment portions 251 extend along a first direction, and multiple first sub-abutment portions 251 are spaced apart along a second direction, wherein the second direction is perpendicular to the first direction. The second sub-abutment portions 252 extend along the second direction and are located between adjacent first sub-abutment portions 251, connecting adjacent first sub-abutment portions 251. It can be understood that the first sub-abutment portions 251 and the second sub-abutment portions 252 are interconnected below the button body 24 to form intersecting structural reinforcing ribs, which improves the structural strength of the button body 24 while reducing the overall weight of the button 20, achieving weight reduction of the button 20. Simultaneously, the first sub-abutment portions 251 and the second sub-abutment portions 252 extend from the bottom of the button body 24 away from the bottom of the button body 24, both extending to the same horizontal plane, thereby making the bottom surface of the abutment portion 25 for actuating the linkage portion 31 flat, so that the abutment portion 25 can be actuated more reliably. Figure 2 The linkage part 31 has a first sub-abutment part 251 that is parallel to the extension direction of the button 20, which allows the button 20 to slide relative to the linkage part when it is pressed, and the sliding direction is the same as the extension direction of the button 20. At the same time, the bottom of the first sub-abutment part 251 and the second sub-abutment part 252 extend to the same plane to form a plane for actuating the linkage part 31, which can also reduce the resistance generated when the button 20 slides relative to the linkage part 31, making the sliding of the button 20 relative to the linkage part 31 smoother, thereby improving the user's pressing feel.

[0068] In some embodiments, such as Figure 5 As shown, the trigger 30 also includes a connecting part 32, one end of which is connected to the linkage part 31, and the other end of which is connected to... Figure 1 The housing 10 is pivotally connected, which can be understood as the linkage 31 being rotatably connected to the housing 10 via the connecting part 32, so that when the button 20 applies a force to the linkage 31, the linkage 31 can rotate about the end of the connecting part 32 connected to the housing 10. Optionally, such as Figure 5As shown, the trigger 30 also includes a folded edge 33, which is connected to the end of the connecting portion 32 that is connected to the housing 10. The extending direction of the folded edge 33 is perpendicular to the extending direction of the connecting portion 32. That is, the folded edge 33 extends from the end of the connecting portion 32 toward the housing 10, so that the connecting portion 32 and the housing 10 can be rotatably connected. At the same time, the folded edge 33 is provided with a mounting structure 331, which can be a mounting hole or a mounting shaft. The folded edge 33 is pivotally connected to the housing 10 through the mounting structure 331. For example, the mounting structure 331 is a mounting hole, and the corresponding housing 10 is provided with a pivot shaft that can cooperate with the mounting hole. By fitting the mounting hole onto the outside of the pivot shaft, the connecting portion 32 and the housing 10 can be pivotally connected. That is, by providing the folded edge 33, a space is provided for the mounting structure 331, so that the connecting portion 32 can be more conveniently pivotally connected to the housing 10.

[0069] In some embodiments, such as Figure 6 As shown, there are multiple connecting portions 32, and the multiple connecting portions 32 are in the second direction (the second direction is as follows). Figure 6 (As indicated by the middle arrow) Located on at least one side of the power generation component 50, the connecting portion 32 can be understood as being disposed on at least one side of the power generation component 50 to reduce the possibility of motion interference between the connecting portion 32 and the power generation component 50 during movement. Optionally, in the second direction, multiple connecting portions 32 are respectively disposed on both sides of the power generation component 50 to reduce the possibility of motion interference between the connecting portions 32 and the power generation component 50 during movement, while making the structure of the self-generating switch 1 more compact, thereby reducing the size of the self-generating switch 1 in the second direction. Simultaneously, at least one connecting portion 32 is provided with a reinforcing portion 34 to increase the structural strength of the connecting portion 32. For example, the reinforcing portion 34 protrudes from the outer surface of the connecting portion 32, and the extending direction of the reinforcing portion 34 is parallel to the extending direction of the connecting portion 32 to increase the bending stiffness of the connecting portion 32. Specifically, in... Figure 1When the button 20 applies a force to the linkage 31, the force generates a bending moment acting on the connecting part 32. Under the action of this bending moment, the connecting part 32 pivots relative to the housing 10, and at the same time, the connecting part 32 undergoes bending deformation under the action of this bending moment. By providing a reinforcing part 34 on the outer surface of the connecting part 32 to increase the bending stiffness of the connecting part 32, the deflection of the bending deformation of the connecting part 32 under the action of this bending moment can be reduced. It should be noted that the bending deformation of the connecting part 32 under the action of bending moment may lead to fatigue failure of the connecting part 32, and the rate of fatigue failure of the connecting part 32 is positively correlated with the magnitude of the deflection of the bending deformation of the connecting part 32. By providing a reinforcing part 34 on the surface of the connecting part 32 to increase the bending stiffness of the connecting part 32, the deflection of the bending deformation of the connecting part 32 under the action of bending moment can be reduced. Thus, while the linkage 31 can trigger the power generation component 50 to generate electrical energy, the possibility of fatigue failure of the connecting part 32 is reduced, and the service life of the connecting part 32 is extended.

[0070] In some embodiments, such as Figure 7 As shown, the self-generating switch 1 also includes a button support portion 61, which is located between the button 20 and the trigger member 30. The button support portion 61 abuts against the contact portion 25 of the button 20. This can be understood as the button support portion 61 applying a contact force to the contact portion 25 of the button 20, allowing the button body 24 to pivot relative to the housing 10 around the button support portion 61. During this pivoting process, the button body 24 applies a force to the linkage portion 31 of the trigger member 30, thereby enabling the contact portion 25 of the button 20 to apply a force to the linkage portion 31 through the button support portion 61, thus actuating the linkage portion 31 and triggering the power generation component 50 to generate electrical energy. Optionally, as... Figure 7 As shown, the button support 61 is a flexible structure that can deform. The trigger 30 abuts against the reset structure 40 so that the trigger 30 can abut against the button support 61, thereby allowing the reset structure 40 to apply abutting force to the abutting part 25 of the button 20 through the trigger 30 and the button support 61.

[0071] In some embodiments, such as Figure 8As shown, there are multiple buttons 20 and multiple button support portions 61. The button support portions 61 are correspondingly arranged below each button 20. Specifically, the number of button support portions 61 is the same as the number of buttons 20, with one button support portion 61 corresponding to each button 20, so that each button 20 is supported by its respective button support portion 61. Meanwhile, partition portions 62 are provided between the button support portions 61 to separate the movement and deformation of different button support portions 61. Specifically, by separating different button support portions 61, the movement and deformation of one button support portion 61 will not be transmitted to other button support portions 61, thereby reducing the mutual influence between the movement and deformation of each button support portion 61, and further reducing the possibility of other buttons 20 being accidentally activated due to the linkage between multiple button support portions 61 when one button 20 is pressed. It should be noted that the partition portion 62 can be any structure capable of isolating the linkage between the button support portions 61, and the specific structure of the partition portion 62 varies depending on the structure of the button support portion 61. For example, adjacent button support portions 61 are spaced apart, and the gap between adjacent button support portions 61 forms a partition portion 62; for example, multiple button support portions 61 are connected to form an integral structure and a groove is provided between adjacent button support portions 61, and the partition portion 62 is formed by the groove between adjacent button support portions 61.

[0072] In some embodiments, such as Figure 9As shown, the self-generating switch 1 also includes an electronic control component 70. The electronic control component 70 can acquire the electrical energy generated by the generating component 50 and perform corresponding functions based on the pressing of different pressing portions 21 of different buttons 20. Specifically, the electronic control component 70 includes a circuit board 71 and a detection switch 72. The circuit board 71 is fixedly connected to the housing 10 and connected to the generating component 50, enabling the circuit board 71 to acquire the electrical energy generated by the generating component 50, thereby realizing the different functions of the self-generating switch 1. Multiple detection switches 72 are provided, each connected to the circuit board 71. These switches can be activated by the first end 22 and the second end 23 of the button 20, respectively. Different areas of the circuit board 71 are triggered by different detection switches 72, allowing the self-generating switch 1 to perform different functions. Specifically, when pressure is applied to the first end 22 or the second end 23 of the button 20, the abutment portion 25 of the button 20 activates the linkage portion 31, causing the linkage portion 31 to trigger the power generation component 50 to generate electrical energy. Simultaneously, the first end 22 or the second end 23 of the button 20 activates the corresponding detection switch 72, allowing the circuit board 71 to acquire the electrical energy generated by the power generation component 50. The circuit board 71 then performs corresponding actions based on the position of the circuit board 71 triggered by the detection switch 72, thus enabling the self-generating switch 1 to simultaneously perform different functions. Optionally, multiple buttons 20 are provided, and the number of detection switches 72 is twice the number of buttons 20. Each detection switch 72 is located below the first end 22 and the second end 23 of each button 20, allowing the first end 22 and the second end 23 of the button 20 to activate their respective detection switches. For ease of explanation, the following example uses the application of the self-generating switch 1 in a smart toilet to illustrate the different functions that the first end 22 and the second end 23 of the different buttons 20 of the self-generating switch 1 can trigger, as well as the specific principles by which the circuit board 71 implements each function.

[0073] like Figure 10As shown, the self-generating switch 1 includes a first button 20A, a second button 20B, and a third button 30C. The first button 20A and the third button 20C are located on both sides of the second button 20B. The first end 22A of the first button and the second end 23C of the third button are used to trigger the opening and closing of the smart toilet lid; the second end 23A of the first button and the first end 22C of the third button are used to trigger the flushing function of the smart toilet; the first end 22B of the second button and the second end 23B of the second button are used to trigger the opening and closing of the smart toilet seat. When the first end 22A of the first button or the second end 23C of the third button is pressed, the first end 22A of the first button or the second end 23C of the third button can trigger the corresponding detection switch, so that the circuit board outputs a first control signal to the seat drive of the smart toilet, thereby controlling the opening and closing of the smart toilet seat; when the second end 23A of the first button or the first end 22C of the third button is pressed, the second end 23A of the first button or the first end 22C of the third button can trigger the corresponding detection switch, so that the circuit board outputs a second control signal to the flushing device of the smart toilet, thereby controlling the flushing device of the smart toilet to flush; when the first end 22B of the second button or the second end 23B of the second button is pressed, the first end 22B of the second button or the second end 23B of the second button can trigger the corresponding detection switch, so that the circuit board outputs a third control signal to the seat drive of the smart toilet, thereby controlling the opening and closing of the seat of the smart toilet.

[0074] In some embodiments, such as Figure 11 As shown, the self-generating switch 1 also includes a detection switch protective layer 63, which is located above the detection switch 72 to protect the detection switch 72. For example, the detection switch protective layer 63 is disposed between the button 20 and the detection switch 72. The detection switch protective layer 63 transmits the force applied by the button 20 to the detection switch 72, increasing the contact area between the button 20 and the detection switch 72, thereby reducing the stress exerted by the button 20 on the detection switch 72 and extending the service life of the detection switch 72. Simultaneously, the stiffness of the detection switch protective layer 63 is greater than a first threshold value; that is, the detection switch protective layer 63 can only deform to activate the detection switch when the force applied by the button 20 on the detection switch protective layer 63 exceeds a certain value, thereby reducing the possibility of accidental activation of the detection switch 72 due to accidental button 20 activation. In some embodiments, such as... Figure 11As shown, the self-generating switch 1 also includes a waterproof component 60, which is located between the button 20 and the detection switch 72. That is, the waterproof component 60 covers the detection switch 72, thereby reducing the possibility of liquid from outside the self-generating switch 1 entering the housing and contacting the detection switch 72, thus causing damage to the detection switch 72. The button support 61 and the detection switch protective layer 63 are both disposed within the waterproof component 60, meaning they are integrated into the waterproof component 60. This makes the structure of the self-generating switch 1 more compact, thus achieving support for the button 20, protection for the detection switch 72, and reducing the possibility of damage to the power generation component 50 and the electronic control component 70 inside the self-generating switch 1 due to contact with liquid entering the self-generating switch 1, without increasing the size of the self-generating switch 1.

[0075] In some embodiments, such as Figure 12 As shown, the housing 10 includes a bottom wall 11 and a side wall 12 surrounding the bottom wall 11. Specifically, the bottom wall 11 and the side wall 12 enclose a receiving cavity 13 with an opening. The trigger 30, reset structure 40, power generation component 50, waterproof component 60, and electronic control component 70 are disposed within the receiving cavity 13. Meanwhile, the button 20 is movably connected to the side wall 12 of the housing 10, and the button 20 covers the opening of the receiving cavity 13, thereby protecting the trigger 30, reset structure 40, power generation component 50, waterproof component 60, and electronic control component 70 within the receiving cavity 13 through the housing 10 and the button 20. Furthermore, as... Figure 14 As shown, the waterproof component 60 is also provided with a limiting boss 64 that can abut against the side wall 12, thereby limiting the relative movement of the waterproof component 60 relative to the housing 10 through the force between the limiting boss 64 and the side wall 12, and improving the waterproof effect of the waterproof component 60.

[0076] In some embodiments, such as Figure 13As shown, the self-generating switch 1 also includes a middle cover 80, which is located between the button 20 and the waterproof component 60. The middle cover 80 has a first through hole 81. A latching assembly 26 is located below the button 20, with at least a portion of the latching assembly 26 extending into the first through hole 81. When the button 20 is pressed, the latching assembly 26 moves toward the waterproof component 60. The latching assembly detachably connects the button 20 to the middle cover 80, improving the ease of installation and removal of the button 20. Furthermore, by allowing the portion of the latching assembly 26 passing through the first through hole 81 to move toward the waterproof component 60, pivotal movement of the button 20 relative to the middle cover 80 is permitted while the button 20 and the middle cover 80 are connected. Specifically, the latching assembly 26 includes multiple latching members 261. One end of each latching member 261 has a hook 262. The end of the latching member 261 with the hook 262 passes through the first through hole 81 and can abut against the side of the middle cover 80 near the waterproof component 60. For ease of explanation, the button 20 with two latching members 261 is used as an example to illustrate the specific structure of the button 20 with latching members 261 and the force applied to the button 20. The latching members 261 are disposed below the button 20, and in the first direction, the two latching members 261 are respectively disposed on both sides of the abutting portion 25. When the button 20 is not pressed, the button support 61 applies an upward abutting force to the abutting part 25 of the button 20, thereby pivotally connecting the button 20 to the housing 10. At the same time, the hook 262 of the latching member 261 abuts against the side of the middle cover 80 near the waterproof member 60. That is, the hook 262 of the latching member 261, which passes through the first through hole 81, hooks the middle cover 80 and applies a downward force to the button 20 to prevent the button 20 from separating from the middle cover 80. The magnitude of the resultant downward force on the two latching members 261 is equal to the magnitude of the upward force on the abutting part 25. At the same time, the downward forces on the two latching members 261 apply equal and opposite torques to the button 20, thereby keeping the button 20 in a balanced state. When button 20 is pressed, the pressed end of button 20 rotates around the abutment portion 25. Simultaneously, the hook 262 of the latching member 261 located below this end moves towards the waterproof component 60. Optionally, the waterproof component 60 is provided with a relief groove. When button 20 is pressed, the hook 262 of the latching member 261 moves within this relief groove, thereby reducing the amount of pressing force required to activate the end of button 20.

[0077] In some embodiments, such as Figure 14 As shown, the lower part of the button body 24 also has a triggering mechanism. Figure 12The detection switch 72 has multiple detection switch contacts 27, which are configured to interact with the first end 22 and the second end 23 of the button 20. This means that by setting the detection switch contacts 27 to actuate the corresponding detection switch 72, the reliability of the button actuating the detection switch 72 is improved. Simultaneously, in the first direction (the first direction is as follows...) Figure 1 As indicated by the middle arrow, the distance between the latching component 26 near the first end 22 and the detection switch contact 27 located at the first end 22, and the distance between the latching component 26 near the second end 23 and the detection switch contact 27 located at the second end 23, are both less than the second threshold. This can be understood as follows: in the first direction, the two latching components 26 are respectively located at both ends below the button 20, and the distance between the detection switch contact 27 located at the corresponding end of the button 20 and the latching component 26 is sufficiently small. This reduces the possibility of the detection switch contact 27 located below the other end of the button 20 being accidentally activated when pressure is applied to one end of the button 20, thereby reducing the possibility of the detection switch 72 located below the other end of the button 20 being accidentally activated. The second threshold can be, for example, 10 mm.

[0078] In some embodiments, such as Figure 15 As shown, when button 20 is not pressed, the distance between the end of the detection switch contact 27 and the detection switch protective layer 63 is greater than the third threshold. That is, when no position of the pressing part 21 between the first end 22 and the second end 23 of button 20 is pressed, the distance between the bottom end of the detection switch contact 27 and the detection switch protective layer 63 is large enough to reduce the false triggering of the detection switch contact 27 due to accidental touch. Figure 12 The probability of detecting switch 72 in the middle. The third threshold can be 1 mm.

[0079] In some embodiments, such as Figure 16As shown, the waterproof component 60 is also provided with receiving grooves 65 for accommodating each latching assembly 26. The portion of the latching assembly 26 passing through the first through hole 81 is located within the receiving groove 65. When the button 20 is pressed, the portion of the latching assembly 26 passing through the first through hole 81 can move within the receiving groove 65, thereby reducing the possibility of movement interference between the latching assembly 26 and the waterproof component 60, and reducing the amount of pressing force required to activate the button 20. Simultaneously, in the first direction, at least two receiving grooves 65 have different distances from the linkage part 31; that is, in the first direction, the distances between the receiving grooves 65 and the linkage part 31 are not entirely the same, thus allowing the receiving grooves 65 to accommodate buttons 20 of different shapes for connection with the housing 10. For example, along the second direction, three receiving slots 65 are spaced apart, wherein the distance between the middle receiving slot 65 and the linkage part 31 in the first direction is greater than the distance between the receiving slots 65 on both sides and the linkage part 31 in the first direction, so that a button with a larger size in the first direction can be matched by the middle receiving slot 65, and a button with a smaller size in the first direction can be matched by the receiving slots 65 on both sides.

[0080] In some embodiments, such as Figure 17 As shown, the waterproof component 60 also includes a linkage part protective layer 66 located above the linkage part 31 to protect the linkage part 31 and at least a portion of the power generation component 50 below the linkage part 31. The middle cover 80 includes a second through hole 82 through which the linkage part protective layer 66 passes, a third through hole 83 through which the detection switch protective layer 63 passes, and a protective part 84 covering at least a portion of the power generation component 50. It can be understood that by providing the second through hole 82 through which the linkage part protective layer 66 passes, the linkage part protective layer 66 can protect the linkage part 31 while simultaneously allowing the button 20 to... Figure 13 The abutment portion 25 can pass through the second through hole 82 and actuate the linkage portion 31; by providing a third through hole 83 through which the detection switch protective layer 63 passes, the detection switch contact 27 can pass through the third through hole 83 and actuate the detection switch 72 while the detection switch protective layer 63 can protect the detection switch 72. Meanwhile, the number of second through holes 82 is at least two, and in the second direction, at least one second through hole 82 is located on each side of the protective portion 84. That is, the second through holes 82 are provided on both sides of the protective portion 84 in the second direction, thereby making the structure of the self-generating switch 1 more compact and reducing the size of the self-generating switch 1 in the second direction. It should be noted that the linkage protective layer 66 and... Figure 7 The button support 61 is integrated into one piece, so that the linkage protective layer 66 can protect the linkage while supporting the button 20, and make the structure of the waterproof component 60 more compact, further reducing the size of the self-generating switch 1.

[0081] In some embodiments, such as Figure 18 As shown, in the second direction, the number of buttons 20 is at least three. The middle button 20 has at least two spaced-apart abutment portions 25, which are located on both sides of the protective portion 84. This means that the abutment portion 25 of the middle button 20 in the second direction can extend into the two second through holes 82 located on both sides of the protective portion 84 and activate the linkage portion 31. It should be noted that the number of buttons 20 can be odd or even. When the number of buttons 20 is even, the middle button 20 in the second direction is the one closer to the power generation component 50 among the two middle buttons 20.

[0082] In some embodiments, such as Figure 19 As shown, the self-generating switch 1 also includes a waterproof component 60, which is located below the button 20. A latching assembly 26 is provided on the inner side of the button 20, and the waterproof component 60 is provided with a corresponding receiving groove 65 for accommodating the latching assembly 26. When the button 20 is pressed, the latching assembly 26 moves into the receiving groove 65. That is, by providing the receiving groove 65, when the button 20 is pressed and the latching assembly 26 moves toward the waterproof component 60, the latching assembly 26 can extend into the receiving groove 65, thereby reducing the possibility of movement interference between the latching assembly 26 and the waterproof component 60.

[0083] In some embodiments, such as Figure 20As shown, the power generation component 50 includes a power generation element 51 and an energy storage element 52. The power generation element 51 is detachably connected to the housing 10. The power generation element 51 is a component capable of generating electrical energy through the principle of electromagnetic induction. For example, the power generation element 51 includes a core made of a magnetically conductive material, a conductive coil surrounding the core, and a magnet in contact with the core, so that the conductive coil is located in the magnetic field generated by the magnet. By changing the strength of the magnetic field or causing the conductive coil and the magnet to undergo relative motion capable of cutting magnetic field lines, an induced electromotive force is generated in the conductive coil. The energy storage element 52 is connected to the power generation element 51. In a first direction, the energy storage element 52 is located in the middle below the button 20 and can contact the linkage part 31. At the same time, at least a portion of the reset structure 40 is located below the energy storage element 52. It can be understood that the energy storage element 52 is located between the linkage part 31 and the reset structure 40. The energy storage component 52 can be activated by the linkage part 31 and reset by the reset structure 40 to trigger the generator 51 to generate electrical energy. The reset structure 40 can also reset the linkage part 31. Specifically, when the button 20 is pressed, the button 20 activates the linkage part 31 to move the energy storage component 52 from the first position to the second position. After the pressing force applied to the button 20 is removed, the reset structure 40 applies a reset force to the energy storage component 52 and the linkage part 31, thereby causing the energy storage component 52 to return from the second position to the first position. At the same time, the linkage part 31 returns to the state before it was subjected to the force of the button 20. When the energy storage component 52 moves from the first position to the second position, and / or when the energy storage component 52 moves from the second position to the first position, the energy storage component 52 triggers the generator 51 to generate electrical energy. Among them, the energy storage device 52 is an elastic element that can store elastic potential energy. When the stored elastic potential energy is greater than a preset threshold, the energy storage device 52 can drive the moving part of the generator 51 to move, thereby increasing the speed of the moving part of the generator 51, thereby increasing the speed at which the conductive coil of the generator 51 cuts the magnetic field lines, and thus increasing the amount of electrical energy generated by electromagnetic induction.

[0084] In some embodiments, such as Figure 21 As shown, the power generation component 51 includes: a sensing component 511, a driving component 512, and a magnetic conductive component 513. The sensing component 511 and... Figure 1 The housing 10 is fixedly connected to the sensing component 511. Placing the sensing component 511 in a changing magnetic field can induce a current within the sensing component 511. One end of the driving component 512 is rotatably connected to the sensing component 511, and the other end of the driving component 512 is fixedly connected to the magnetically conductive component 513. The magnetically conductive component 513 and... Figure 21The energy storage component 52 is fixedly connected and can rotate around the end of the drive component 512 connected to the sensing component 511 under the drive of the energy storage component 52. The magnetic conductive component 513 can generate a magnetic field, and during the rotation of the magnetic conductive component 513 relative to the sensing component 511, it can change the magnetic field around the sensing component 511, thereby generating an induced current in the sensing component 511.

[0085] In some embodiments, such as Figure 22 As shown, the abutting part 25 extends from the lower surface of the button body 24 away from the button body 24, forming a bottom surface that can actuate the linkage part 31. This bottom surface is tangent to the top surface of the linkage part 31, so that most of the force exerted by the abutting part 25 on the linkage part 31 is used to drive the pivoting movement of the linkage part 31 relative to the housing 10. Specifically, the force exerted by the abutting part 25 on the linkage part 31 can be decomposed into two component forces. One component force is perpendicular to the extension direction of the connecting part 32, which is used to drive the linkage part 31 and the connecting part 32 to pivot relative to the housing 10 and cause the linkage part 31 to trigger the power generation component 50 to generate electrical energy. The other component force is parallel to the extension direction of the connecting part 32, which is used to cause the connecting part 32 to deform along the extension direction of the connecting part 32. For ease of explanation, the component of force perpendicular to the extension direction of the connecting part 32 is called the positive component, and the component of force parallel to the extension direction of the connecting part 32 is called the tangential component. If most of the force exerted by the button 20 on the linkage part 31 is decomposed into the tangential component, the button 20 will not only have difficulty driving the connecting part 32 to pivot relative to the housing 10, but will also cause the connecting part 32 to produce a large tangential deformation. At the same time, since the force exerted by the button 20 on the linkage part 31 is a dynamic load, the connecting part 32 will produce alternating tangential deformation, which will make the connecting part 32 more prone to fatigue failure and shorten the service life of the connecting part 32. By setting the bottom surface of the abutment portion 25 to be tangent to the top surface of the linkage portion 31, the direction of the force exerted by the abutment portion 25 on the linkage portion 31 can be made approximately perpendicular to the extension direction of the connecting portion 32. This decomposes most of the force exerted by the abutment portion 25 on the linkage portion 31 into a positive component, thereby reducing the magnitude of the force required to activate the linkage portion 31 and also reducing the alternating tangential deformation of the connecting portion 32, thus extending the service life of the connecting portion 32. It should be noted that the bottom surface of the abutment portion 25 and the top surface of the linkage portion 31 can be any shape capable of forming a tangential relationship. For example, the bottom of the abutment portion 25 protrudes to form an arc-shaped surface, and the top surface of the linkage portion 31 forms a plane tangent to this arc-shaped surface; or, for example, at least a portion of the linkage portion 31 protrudes towards the abutment portion 25 to form an arc-shaped surface, and the bottom surface of the abutment portion 25 forms a plane tangent to this arc-shaped surface.

[0086] In some embodiments, such as Figure 23 As shown, the linkage part 31 includes a first arc-shaped part 311, which protrudes toward the button 20 and abuts against the bottom surface of the button body 24, thereby making the transmission of the button relative to the linkage part more stable; optionally, the first arc-shaped part 311 directly abuts against the bottom surface of the button body 24; optionally, the abutting part 25 protrudes from the bottom surface of the button body 24, and the first arc-shaped part 311 abuts against the bottom surface of the button body 24 through the abutting part 25.

[0087] In some embodiments, such as Figure 23 As shown, the linkage also includes a second arc-shaped portion 312 and an arc-shaped connecting portion 313 connecting the first arc-shaped portion 311 and the second arc-shaped portion 312. The second arc-shaped portion 312 is disposed on the side of the first arc-shaped portion 311 away from the generator 51, and the arc-shaped connecting portion 313 abuts against the energy storage member 52. This makes the transmission of the linkage relative to the energy storage member more stable. By disposing of the second arc-shaped portion 312 on the side away from the generator 51, the arc-shaped connecting portion 313 can apply a force to the energy storage member 52 from the end of the energy storage member 52 away from the generator 51, thereby applying a larger torque to the energy storage member 52 and reducing the magnitude of the force required to trigger the energy storage member 52 to rotate relative to the generator 51 and generate electrical energy. Optionally, the arc-shaped connecting portion 313 protrudes towards the energy storage component 52, thereby forming an arc-shaped bottom surface that is tangent to the top surface of the energy storage component 52. This allows most of the force exerted by the linkage portion 31 on the energy storage component 52 to drive the energy storage component 52 to rotate relative to the power generation component 51, further reducing the amount of force required to trigger the rotation of the energy storage component 52 relative to the power generation component 51 and to trigger the power generation component 51 to generate electrical energy.
