Description

Technical Field

[0001] This utility model relates to a control switch, and more specifically, to a self-generating wireless switch that is easy to operate. Background Technology

[0002] In recent years, with the rapid development of smart homes, the use of self-powered wireless switches has also increased. Compared with traditional battery-powered wireless switches, they have advantages such as no need to replace batteries and lightweight design.

[0003] The working principle of a self-generating wireless switch is that pressing a switch button triggers an internal self-generating module through a transmission structure, changing the direction of the magnetic field and generating an induced current in the induction coil to provide power to the wireless control circuit system. For example, the multi-gang self-generating switch and signal transmitter disclosed in Chinese Patent Publication No. CN215644208U (publication date: January 25, 2022) includes a base, a linkage mechanism, a self-generating module, a reset mechanism, and a switch panel. The switch panel is fastened to the base and includes multiple switch buttons rotatably connected to the base. The linkage mechanism is located below the switch panel and rotatably connected to the base. The linkage mechanism can move with the switch button when any switch button is pressed. The self-generating module is connected to the linkage mechanism and can be driven by the linkage mechanism to generate power when any switch button is pressed. The reset mechanism is located below the linkage mechanism and is used to reset the linkage mechanism and the switch buttons when the press is released. For example, Chinese Patent Publication No. CN220984411U discloses a self-generating wireless switch (publication date: May 17, 2024), which includes a bottom shell, at least one switch button, a mechanism, and a waterproof sleeve. The switch button is rotatably mounted on the bottom shell, forming an accommodating cavity with the bottom shell. The mechanism is disposed within the accommodating cavity and includes a self-generating module and an electronic control board. The electronic control board has at least one touch control corresponding to the switch button. The waterproof sleeve is disposed within the accommodating cavity and covers the mechanism. The waterproof sleeve has at least one buffer spring portion protruding from it, corresponding to the switch button. When the switch button is pressed, the switch button first squeezes the buffer spring portion and then triggers the touch control. When the switch button is released, the buffer spring portion returns to its original position and drives the switch button to reset. Based on the aforementioned existing patents, it is not difficult to find that the button pressing position of existing self-generating wireless switches is basically located near the spring of the self-generating module. This design means that the pressing force of the button needs to be greater than the toggle force of the self-generating module. Under the action of magnetic attraction and rebound spring, the toggle force is relatively large, which makes it more difficult to press the self-generating wireless switch and the pressing stroke is relatively long, affecting the operation feel of the self-generating wireless switch. Summary of the Invention

[0004] 1. Technical problem to be solved by the utility model

[0042] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0043] [Example]

[0044] Combination Figures 1 to 4 As shown, this embodiment of a labor-saving self-generating wireless switch includes:

[0045] The bottom shell 1 serves as the mounting base for the entire self-generating wireless switch. A self-generating module 2 is fixedly installed inside the bottom shell 1. The self-generating module 2 has a spring 2-1 for toggling to generate an induced current.

[0046] The pressing block 3 is slidably installed in the bottom shell 1 along a direction perpendicular or approximately perpendicular to the bottom shell 1. A reset member is provided between the pressing block 3 and the bottom shell 1 for elastically resetting the pressing block 3. The free end of the spring piece 2-1 extends into the slot of the pressing block 3. When the pressing block 3 is pressed down, the spring piece 2-1 first bends and generates rebound potential energy. When the rebound critical point is reached, the spring piece 2-1 rebounds rapidly in the slot of the pressing block 3 to switch the direction of the magnetic field in the self-generating module 2, thereby generating an induced current. After the pressing force of the pressing block 3 disappears, the pressing block 3 is reset under the action of the reset member, which drives the spring piece 2-1 to reset to the initial position, waiting for the next pressing trigger.

[0047] The transmission rocker 4 is movably installed inside the bottom shell 1 and acts on the pressing block 3 to drive the pressing block 3 to move. The transmission rocker 4 can cover a larger area of ​​the switch panel, so that the pressing block 3 can be driven to move through the transmission rocker 4 when pressing at different pressing positions.

[0048] The switch button 7 is movably mounted on the bottom shell 1 and acts on the transmission rocker 4, which is used to drive the transmission rocker 4 to move by pressing.

[0049] In this embodiment, a lever arm 4-1 and a pressing arm 4-2 (e.g., on the same side of the transmission rocker 4) are respectively provided. Figure 4 As shown), the end of lever arm 4-1 is rotatably engaged with the bottom shell 1, the end of pressing arm 4-2 abuts against pressing block 3, and the switch button 7 is in contact with the side of transmission rocker plate 4 away from lever arm 4-1 and pressing arm 4-2. Furthermore, the lever arm length of lever arm 4-1 is greater than the lever arm length of pressing arm 4-2. (Refer to...) Figure 2 As shown, the force F acting on the transmission rocker 4 of the switch button 7 is the length of its lever arm from the switch button 7 to the rotation support point, and the reaction force f acting on the pressing arm 4-2 of the pressing block 3 is the length of its lever arm from the pressing block 3 to the rotation support point. According to the lever balance principle, the force F acting on the transmission rocker 4 of the switch button 7 is less than the reaction force f acting on the pressing arm 4-2 of the pressing block 3. Therefore, a smaller force can be used to drive the self-generating module 2, which effectively reduces the pressing force required for the button and makes the operation of the self-generating wireless switch easier and more labor-saving. It has the advantages of simple structure, easy operation, and short pressing stroke.

[0050] like Figures 2 to 4 as well as Figure 6As shown, in this embodiment, the end of the switch button 7 furthest from the transmission rocker 4 is rotatably connected to the bottom shell 1. The other end of the switch button 7 is provided with a contact protrusion 7-3 for engaging with the transmission rocker 4. This design results in a shorter pressing stroke for the switch button, and a more comfortable operating feel and button feedback. Specifically, the side of the switch button 7 furthest from the transmission rocker 4 is provided with a button rotating part 7-1, and the side of the bottom shell 1 furthest from the transmission rocker 4 is provided with a rotating support part 1-1. The button rotating part 7-1 is rotatably connected to the rotating support part 1-1 via a rotating shaft Z1. The other side of the switch button 7 is provided with a buckle 7-2, and the other side of the bottom shell 1 is provided with a limiting groove 1-2. The buckle 7-2 can be restricted to move within the limiting groove 1-2. Using this switch button 7, its structure is simple, and it is quick and convenient to assemble with the bottom shell 1.

[0051] In addition, a circuit board 5 is located inside the bottom shell 1 on the side away from the transmission rocker 4. The circuit board 5 has a contact switch 6 for recognizing the pressing signal. Integrating the circuit board 5 on one side of the self-generating module 2 makes the structure more compact and helps to reduce the overall thickness of the self-generating wireless switch, making the switch lighter and thinner. The aforementioned switch button 7 can be a single-button, double-button, or triple-button structure. When the switch button 7 is a double-button or triple-button structure, the circuit board 5 has a contact switch 6 corresponding to the corresponding button position. When the corresponding switch button 7 is pressed, the corresponding contact switch 6 is triggered to generate a signal, thereby recognizing which switch button 7 has been pressed. This can meet the needs of switches with different numbers of buttons, and only one self-generating module is required, resulting in lower manufacturing costs. Figure 1 This is a three-button self-generating wireless switch. Figure 7 This is a self-generating wireless switch with a double-bond structure. Figure 8 This shows a self-generating wireless switch with a single-key structure.

[0052] Reference Figure 4 and Figure 5 As shown, in this embodiment, the bottom shell 1 has a limiting buckle 1-3 and a rotating seat 1-4 on both sides of the self-generating module 2. The limiting buckle 1-3 is fastened to the upper side of the end of the lever arm 4-1. A rotating shaft 4-1a is provided on one side of the rotating seat 1-4, located within a rotating groove 1-4a on the upper part of the rotating seat 1-4. The rotating shaft 4-1a is a protrusion extending to one side, and the rotating groove 1-4a is a recessed structure. The limiting buckle 1-3 and the rotating seat 1-4 support the end of the lever arm 4-1 from both above and below. One side of the rotating groove 1-4a is higher, which restricts the horizontal movement of the rotating shaft 4-1a, thus allowing the rotating shaft 4-1a to rotate stably within the rotating groove 1-4a. This rotating structure is simple and facilitates the rapid assembly of the transmission rocker. (Refer to...) Figure 4 As shown, the aforementioned transmission rocker 4 is roughly "E" shaped, and the length of the pressing arm 4-2 is slightly shorter than that of the lever arm 4-1.

[0053] This embodiment provides a self-generating wireless switch that is easy to operate. Both the self-generating module 2 and the pressing block 3 are indirectly mounted inside the bottom shell 1 via a mounting base 8. The reset element is a reset spring 9 located between the pressing block 3 and the mounting base 8. Figure 6 As shown, the mounting base 8 has a self-generating module mounting cavity and a pressing block sliding cavity. The self-generating module 2 is installed in the self-generating module mounting cavity of the mounting base 8, and the pressing block 3 is installed in the pressing block sliding cavity of the mounting base 8. A latch for limiting the pressing block 3 is also provided on the side wall of the pressing block sliding cavity. The top of the pressing block 3 has a groove for contacting and engaging with the pressing arm 4-2, and the groove opening is a trumpet-shaped structure. Using the mounting base 8 to install the self-generating module 2 and the pressing block 3 easily ensures assembly accuracy and simplifies the bottom shell structure. Furthermore, the self-generating module 2 is fixed in the mounting base 8 by the latch structure, the pressing block 3 is limited in the mounting base 8 by the latch, and the mounting base 8 is installed in the bottom shell 1 by the fixing latches 1-5 provided in the bottom shell 1, making assembly convenient.

[0054] This utility model discloses a self-generating wireless switch that requires less effort to operate. Utilizing the lever principle of a transmission rocker and optimized switch structure, the lever arm's lever arm length is greater than the pressing arm's lever arm length, effectively reducing the pressing force required for the button. This makes the self-generating wireless switch easier and less strenuous to operate, offering advantages such as simple structure, convenient operation, and short pressing stroke. Furthermore, the shorter pressing stroke of the switch button results in a more comfortable operating feel and button feedback. Integrating the circuit board on one side of the self-generating module makes the structure more compact, reducing the overall thickness of the self-generating wireless switch and making it thinner and lighter.

[0055] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
