Description

TECHNICAL FIELD

[0001] The present application relates to a switch device, in particular to a self-power generating switch device. BACKGROUND

[0002] Switches are common devices in power systems, which are used to open a circuit, disconnect a circuit or transfer current to other circuits, to control the on-off or operation of electrical equipment, such as controlling the light on-off or the sound of a doorbell in a home environment.

[0003] Currently, the common power supply mode of switches is mainly mains or battery. The mains power supply needs to set up complex wiring, which not only affects the environmental aesthetics, but also cannot change the position of the switch at will. The battery power supply needs to be replaced or charged when the battery power is exhausted, which causes inconvenience and trouble in use and affects the service life of the switch. In addition, the replaced battery also pollutes the environment. SUMMARY

[0004] In view of the above, in an embodiment, a self-power generating switch device is provided, which includes a housing, a switch, a power generation module and a movable seat. The housing includes an assembly port. The switch is arranged in the assembly port and located at an initial position, and the switch can be sequentially moved to a first trigger position and a second trigger position in the same moving direction relative to the housing. The power generation module is arranged in the housing. The movable seat is movably arranged in the housing and abuts between the power generation module and the switch. When the switch is moved from the initial position to the first trigger position, the switch presses the movable seat to trigger the power generation module to generate a first electric signal. When the switch is moved from the first trigger position to the second trigger position, the switch releases the movable seat to trigger the power generation module to generate a second electric signal.

[0005] Further, the power generation module includes a trigger spring and a power generation piece coupled with each other, and the movable seat abuts between the trigger spring and the switch.

[0006] Further, the switch comprises a linkage member provided with a pressing protrusion, and the movable seat is provided with a guide protrusion adjacent to the pressing protrusion and comprising a first side, a second side and a top end, the first side and the second side are connected to opposite sides of the top end respectively; when the switch is moved from the initial position to the first trigger position, the pressing protrusion moves along the first side to the top end to press the movable seat and drive the trigger leaf to move away from the switch, so that the trigger leaf triggers the power generator to generate the first electric signal; when the switch is moved from the first trigger position to the second trigger position, the pressing protrusion moves from the top end along the second side, so that the trigger leaf moves towards the switch and abuts against the movable seat to trigger the power generator to generate the second electric signal.

[0007] Further, the linkage member and the housing are further provided with an elastic member, and when the switch is moved to the second trigger position, the elastic member further pushes the linkage member, so that the switch is sequentially moved to the first trigger position and the initial position relative to the housing in a recovery direction opposite to the moving direction.

[0008] Further, when the switch is moved from the second trigger position to the first trigger position, the pressing protrusion moves along the second side to the top end to press the movable seat and drive the trigger leaf to move away from the switch, so that the trigger leaf triggers the power generator to generate a third electric signal; when the switch is moved from the first trigger position to the initial position, the pressing protrusion moves from the top end along the first side, so that the trigger leaf moves towards the switch and abuts against the movable seat to trigger the power generator to generate a fourth electric signal.

[0009] Further, the linkage member is provided with a containing groove, and the elastic member is contained in the containing groove.

[0010] Further, the trigger leaf has an adjustable distance, and the thickness of the guide protrusion is greater than or equal to the adjustable distance.

[0011] Further, the number of the pressing protrusions is two or more, and the plurality of pressing protrusions are arranged on the linkage member in the moving direction.

[0012] Further, the number of the guide protrusions is two or more, and the plurality of guide protrusions are arranged on the movable seat in the moving direction.

[0013] Further, the moving direction of the switch is a linear direction or a rotating direction.

[0014] Further, the movable seat has a moving direction, which is perpendicular to the moving direction.

[0015] Further, the self-generating switch device further comprises a wireless communication module, which is coupled to the power generation module, and the wireless communication module sends a wireless control signal according to the first electric signal and the second electric signal.

[0016] In summary, according to the self-generating switch device of the embodiment of the present application, when the switch moves relative to the shell, the movable seat can be actuated to trigger the power generation module to generate electric signals, and the corresponding device can be driven to operate by the electric signals. Therefore, the self-generating switch device of the embodiment of the present application does not need to be installed with a battery for power supply, thereby improving the service life and being more environmentally friendly, and does not need to be installed with a complex circuit to connect to the mains, thereby being easy to change the setting position.

[0017] In addition, the switch of the embodiment of the present application moves in the same moving direction to accumulate two electric signals (i.e., the first electric signal and the second electric signal), so as to ensure that the electric power is sufficient to drive the corresponding device to operate, and to avoid the problem that the self-generating switch device is disabled due to human operation factors.

[0051] Various embodiments are presented in the following detailed description with reference to the accompanying drawings, however, the embodiments are merely presented as examples and do not limit the scope of the present application. In addition, the drawings of the embodiments are omitted of some elements to clearly show the technical features of the present application. The same reference numerals will be used to denote the same or similar elements throughout the drawings.

[0052] Figure 1 This is a perspective view of the first embodiment of the self-generating switch device 1 of the present invention. Figure 2 This is an exploded perspective view of the first embodiment of the self-generating switch device 1 of the present invention. Figure 1 and Figure 2 As shown, the self-generating switch device 1 includes a housing 10, a switch 20, a power generation module 30 and a movable base 40. The self-generating switch device 1 can be used to control the opening and closing or operation of electrical equipment.

[0053] like Figure 1 and Figure 2 As shown, the housing 10 is hollow and includes an assembly port 11. Here, the assembly port 11 is provided on one side of the housing 10 and communicates with the internal space of the housing 10. The assembly port 11 is used for assembling the switch 20. In some embodiments, the housing 10 may be an assembled structure. Figure 2 As shown, the housing 10 of this embodiment is assembled from a first shell plate 101 and a second shell plate 102 . For example, the first shell plate 101 and the second shell plate 102 can be assembled and fixed by adhesion, welding, snap fastening or locking.

[0054] Figure 3 1 is a cross-sectional view of the first embodiment of the self-generating switch device 1 of the present invention. Figures 1 to 3 As shown, the switch 20 includes a control end 26 and a linkage 21 connected to the control end 26. The switch 20 is assembled at the assembly opening 11 of the housing 10 and is located in the initial position (eg, Figure 3 The switch 20 is positioned as shown. The control end 26 of the switch 20 is exposed outside the housing 10 for user operation. The linkage 21 of the switch 20 is located within the housing 10 and is provided with a pressing protrusion 22. In this embodiment, the control end 26, linkage 21, and pressing protrusion 22 are integrally formed. The linkage 21 is rod-shaped, and the pressing protrusion 22 is protruding from one side of the linkage 21, but this is not limiting.

[0055] In some embodiments, the switch 20 can move relative to the housing 10 in the same direction, where the direction of movement can be linear or rotational, depending on the type of switch 20. For example, if the switch 20 is a push switch or a toggle switch, the direction of movement of the switch 20 relative to the housing 10 is a linear direction. If the switch 20 is a rotary switch, the direction of movement of the switch 20 relative to the housing 10 is a rotational direction (e.g., clockwise or counterclockwise).

[0056] like Figure 3 and Figure 4 As shown, Figure 4FIG. 1 is a cross-sectional view of the self-generating switch device 1 in a first trigger position. In this embodiment, the switch 20 is a push switch, and when the operating end 26 is pressed, the switch 20 can be linearly moved (i.e., the above-mentioned moving direction, as indicated by arrow L1) toward the inside of the housing 10 as a whole.

[0057] For example, Figure 1 , Figure 2 and Figure 3 , the power generation module 30 is disposed in the housing 10 and spaced apart from the switch 20, and the power generation module 30 includes a trigger spring 31 and a power generation piece 32 coupled to each other, that is, the trigger spring 31 can be directly or indirectly connected to the power generation piece 32. In some embodiments, the above-mentioned power generation piece 32 can have a power generation coil, and when the trigger spring 31 moves to different positions relative to the power generation piece 32, the power generation coil of the power generation piece 32 can be triggered to generate an electrical signal, respectively.

[0058] For example, Figure 1 , Figure 2 and Figure 3 , the movable seat 40 is movably disposed in the housing 10 and abuts between the trigger spring 31 of the power generation module 30 and the connecting member 21 of the switch 20. For example, the trigger spring 31 has a spring force toward the connecting member 21, so that the trigger spring 31 can abut against the movable seat 40 away from the connecting member 21 in a position (as shown in the position of the trigger spring 31 in Figure 3 , so that the side of the movable seat 40 close to the connecting member 21 can abut against the connecting member 21. In addition, the side of the movable seat 40 close to the connecting member 21 is provided with a guide protrusion 41, the guide protrusion 41 is adjacent to the abutting protrusion 22 on the connecting member 21 and includes a first side surface 411, a second side surface 412 and a top end 413, the first side surface 411 and the second side surface 412 are connected to opposite sides of the top end 413, respectively. In this embodiment, the first side surface 411 and the second side surface 412 are inclined surfaces, and the cross section of the guide protrusion 41 is triangular, but this is not limited. In some embodiments, the first side surface 411 and the second side surface 412 can be arc surfaces or curved surfaces, or the first side surface 411 and the second side surface 412 can be different shapes (for example, the first side surface 411 is an inclined surface, and the second side surface 412 is an arc surface), and the cross section of the guide protrusion 41 can have different shapes (for example, semicircular, wedge-shaped or other irregular shapes).

[0059] In some embodiments, the cross section of the abutting protrusion 22 on the connecting member 21 can also be triangular, semicircular, wedge-shaped or other irregular shapes, which will not be described here. In addition, the cross section shape of the abutting protrusion 22 can be the same as or different from the cross section shape of the guide protrusion 41, which is not limited.

[0060] For example, Figure 3 , Figure 4 andFigure 5 As shown, the switch 20 can move from the initial position to the first trigger position and the second trigger position in sequence in the same movement direction relative to the housing 10, and the first trigger position and the second trigger position can respectively trigger the power generation module 30 to generate and accumulate two electrical signals to ensure that the power is sufficient to drive the corresponding device to operate and avoid the problem of failure of the self-generating switch device 1 due to human operation factors. This is detailed below with reference to the drawings in the specification.

[0061] like Figure 3 As shown in this embodiment, when the switch 20 is in the initial position, which is the position where the switch 20 is assembled to the assembly opening 11 of the housing 10 and has not been operated (e.g., pressed), the pressing protrusion 22 on the linkage 21 of the switch 20 is adjacent to the operating end 26 of the switch 20 relative to the guide protrusion 41 of the movable seat 40. Figure 4 As shown, when the control end 26 is pressed, the switch 20 as a whole can continue to move in the direction of movement inside the housing 10 (as shown by the arrow L1). Figure 3 The switch 20 shown in the position) moves in the above-mentioned moving direction to the first trigger position (as shown in the Figure 4 20 is in the position shown in the figure), during the movement, the pressing protrusion 22 on the linking member 21 moves along the first side surface 411 of the guiding protrusion 41 to the top 413, so as to press the movable seat 40 to move in the direction away from the switch 20 (here, the moving direction of the movable seat 40 is perpendicular to the moving direction of the switch 20, but this is not limited thereto), and the movable seat 40 more synchronously drives the trigger spring 31 to move in the direction away from the switch 20, for example, the trigger spring 31 is pressed by the movable seat 40 and Figure 3 The top position of the power generating element 32 moves to the compressed position (such as Figure 4 The trigger spring 31 is positioned as shown in the figure), so that the trigger spring 31 accumulates elastic force and triggers the generator 32 to generate a first electrical signal (i.e., to generate a transient pulse current). In other words, the first trigger position is the position where the pressing protrusion 22 on the linkage 21 of the switch 20 presses against the top 413 of the guide protrusion 41 of the movable seat 40, thereby triggering the generator module 30 to generate the first electrical signal.

[0062] Then, if Figure 5 As shown, when the control end 26 of the switch 20 is continuously pressed and moves in the above-mentioned moving direction (such as the direction indicated by the arrow L1), the switch 20 is moved from the first trigger position (such as Figure 4 The switch 20 shown in the position) moves to the second trigger position (as shown in the Figure 5When the switch 20 is moved to the second trigger position (as shown in the position of the switch 20), the pressing protrusion 22 on the link member 21 will move from the top end 413 to the second side 412 of the guide protrusion 41 during the movement, so as to release the movable seat 40, and the trigger spring 31 can move to the direction close to the switch 20 by the accumulated elastic force and abut against the side of the movable seat 40 away from the link member 21, so that the trigger spring 31 is moved from the pressed position to the abutting position (as shown in the position of the trigger spring 31) Figure 4 . Figure 3 . Figure 5 , so that the trigger spring 31 triggers the power generation member 32 to generate the second electric signal (i.e. to generate a momentary pulse current), that is, the above-mentioned second trigger position is the position of the pressing protrusion 22 on the link member 21 of the switch 20 moving from the top end 413 to the second side 412, so as to release the movable seat 40 and trigger the power generation module 30 to generate the second electric signal.

[0063] In summary, according to the self-power generation switch device 1 of the embodiment of the present application, when the switch 20 is moved relative to the housing 10, the movable seat 40 and the trigger spring 31 can be actuated to trigger the power generation member 32 to generate an electric signal, and the electric signal (i.e. the above-mentioned first electric signal and the second electric signal) can be used for power supply, so as to drive the corresponding device to operate according to the electric signal.

[0064] For example, as shown in Figure 4 and Figure 5 , the self-power generation switch device 1 can include a wireless communication module 50, the wireless communication module 50 is coupled to the power generation module 30 and wirelessly connected to one or more electrical equipment (such as a television, an air conditioner or a lamp, etc. household electrical appliances, or other commercial electrical appliances), and the wireless communication module 50 can send a wireless control signal to control the corresponding electrical equipment according to the first electric signal and the second electric signal. Therefore, the self-power generation switch device 1 of the embodiment of the present application does not need to install a battery for power supply, so as to improve the service life and be more environmentally friendly, and does not need to install a complex line connection to the mains, so as to be easy to change the setting position.

[0065] In addition, the switch 20 of the embodiment of the present application can be moved in the same direction relative to the housing 10 to accumulate two electric signals, so as to ensure that the power is sufficient to drive the corresponding device to operate. For example, it is assumed that the wireless communication module 50 needs 1 volt of voltage to start, and the power generation member 32 can generate an electric signal of 0.5 volt each time triggered by the trigger spring 31, accordingly, by Figure 4 and Figure 5In the embodiment, the switch 20 can accumulate two electric signals (i.e. the first electric signal and the second electric signal) in the pressing stroke, and a 1-volt voltage can be generated to successfully start the operation of the corresponding device without other artificial operations (e.g. the operation of releasing the switch 20), so as to avoid the problem of the self-generating switch device 1 being disabled due to the artificial improper operation factors (e.g. the user does not release or releases too slowly after pressing the switch 20).

[0066] In some embodiments, the signal transmission range of the wireless communication module 50 depends on the type of hardware or the signal transmission method. Specifically, the wireless communication module 50 can establish a short-distance or long-distance communication connection to transmit data, such as a Bluetooth module, a Wifi module, a Wireless Local Area Networks (WLAN) module, a 3G / 4G module, a Near Field Communication (NFC) module, or a Low Power Wide Area Network (LPWAN) module, and the present application is not limited thereto.

[0067] For example, as shown in FIG. 1, the switch 20 is in the initial position, and the trigger spring 31 is in the top position. When the user presses the switch 20, the trigger spring 31 is moved to the pressed position, and the trigger spring 31 generates the first electric signal. Figure 4 With Figure 5 As shown in FIG. 1, when the switch 20 moves between the first trigger position and the second trigger position, the trigger spring 31 has a movable distance D, such as the shortest distance between the top position and the pressed position of the trigger spring 31. In the embodiment, the thickness T of the guide protrusion 41 of the movable seat 40 is greater than or equal to the movable distance D of the trigger spring 31 (for example, the thickness T of the guide protrusion 41 is 1 mm, and the movable distance D of the trigger spring 31 is 0.8 mm), so that when the switch 20 moves from the initial position to the first trigger position, the movable seat 40 can move 1 mm towards the trigger spring 31, ensuring that the trigger spring 31 can move the above-mentioned movable distance D to successfully trigger the power generation piece 32 to generate an electric signal.

[0068] For example, as shown in FIG. 1, the switch 20 is in the initial position, and the trigger spring 31 is in the top position. When the user presses the switch 20, the trigger spring 31 is moved to the pressed position, and the trigger spring 31 generates the first electric signal. Figure 4 With Figure 5As shown, in one embodiment, an elastic member 25 is further disposed between the linkage member 21 of the switch 20 and the housing 10. The elastic member 25 abuts between the linkage member 21 and the housing 10. For example, the elastic member 25 may be a spring, but is not limited thereto. Thus, when the switch 20 is compressed and moves sequentially from its initial position to the first trigger position and the second trigger position in the same movement direction (as indicated by arrow L1), the elastic member 25 is compressed and accumulates elastic force. Therefore, when the switch 20 is released, the elastic member 25 uses the accumulated elastic force to push against the linkage member 21, causing the switch 20 to move sequentially from the second trigger position to the first trigger position and back to the initial position in a return direction opposite to the movement direction relative to the housing 10, ready for the next user operation.

[0069] Continuing from the above, when the switch 20 moves from the second trigger position to the first trigger position, during this movement, the pressing protrusion 22 on the linkage 21 moves along the second side surface 412 of the guide protrusion 41 to the top 413, pressing against the movable seat 40 to drive the trigger spring 31 away from the switch 20, causing the trigger spring 31 to accumulate elastic force and trigger the generator 32 to generate a third electrical signal (i.e., generate a transient pulse current). When the switch 20 returns from the first trigger position to the initial position, during this movement, the pressing protrusion 22 on the linkage 21 moves from the top 413 of the guide protrusion 41 along the first side surface 411, causing the switch 20 to release the movable seat 40. The trigger spring 31, due to the accumulated elastic force, moves toward the switch 20 and presses against the side of the movable seat 40 away from the connecting member 21, causing the trigger spring 31 to move toward the switch 20, triggering the generator 32 to generate a fourth electrical signal (i.e., generate a transient pulse current). Thus, by disposing the elastic member 25 , the switch 20 can accumulate two electrical signals (ie, the third electrical signal and the fourth electrical signal) during the release process, thereby further ensuring that the power is sufficient to drive the corresponding device to operate or be used by other electronic components.

[0070] like Figure 3 As shown, in this embodiment, the linkage member 21 of the switch 20 is further provided with a receiving groove 23, and the elastic member 25 is received in the receiving groove 23 to prevent the elastic member 25 from deflecting during the actuation of the switch 20, thereby improving the stability of the switch 20 during operation.

[0071] like Figure 6 FIG. 2 is a cross-sectional view of a second embodiment of a self-generating switch device 2 according to the present invention. Figure 3The difference between the embodiment and the first embodiment is that the number of the pressing protrusions 22 on the linkage 21 of the self-power generating switch device 2 is more than two, and the plurality of pressing protrusions 22 are arranged along the moving direction of the switch 20. In addition, when the switch 20 is at the initial position, the plurality of pressing protrusions 22 are adjacent to the operating end 26 of the switch 20 relative to the guide protrusion 41 of the movable seat 40. In the embodiment, the linkage 21 of the self-power generating switch device 2 includes two pressing protrusions, which are the pressing protrusion 22 and the pressing protrusion 22'. It should be understood that the number of the pressing protrusions on the linkage 21 is not limited to two, and the number of the pressing protrusions can be any positive integer N, N≥1. When the switch 20 moves relative to the housing 10 in a moving direction (for example, the direction shown by the arrow L1), the pressing protrusion 22 moves along the first side surface 411 of the guide protrusion 41 to the top end 413 in the moving direction, the movable seat 40 is pressed and drives the trigger spring 31 to move away from the switch 20, the trigger spring 31 accumulates elastic force and triggers the power generating member 32 to generate a first electric signal. The switch 20 continues to be pressed and moves in the same moving direction (for example, the direction shown by the arrow L1), the pressing protrusion 22 moves along the second side surface 412 from the top end 413 of the guide protrusion 41, so that the movable seat 40 is released, the trigger spring 31 moves to the abutting position from the pressed position by the accumulated elastic force and abuts against one side of the movable seat 40 away from the linkage 21, so that the trigger spring 31 is restored to the abutting position and triggers the power generating member 32 to generate a second electric signal. If the operating end 26 of the switch 20 continues to be pressed, the switch 20 can continue to move in the same moving direction (for example, the direction shown by the arrow L1) to trigger the power generating member 32 again by the other pressing protrusion 22' and the guide protrusion 41, so that the movable seat 40 and the trigger spring 31 are driven again, and the power generating member 32 further accumulates two electric signals, so that the switch 20 can accumulate four electric signals in one complete pressing stroke, which further ensures that the electric power is sufficient to drive the corresponding device to operate. The pressing protrusion 22' has a similar structure to the pressing protrusion 22, so the driving relationship between the pressing protrusion 22' and the guide protrusion 41 is similar to the driving relationship between the pressing protrusion 22 and the guide protrusion 41, which will not be described here. Figure 5 Figure 5 Figure 5

[0072] Figure 7 Figure 3 ​​​​​The difference between the embodiments is that the number of guide protrusions 41 on the movable seat 40 of the self-generating switch device 3 is more than two, and the guide protrusions 41 are arranged along the moving direction of the switch 20. In addition, when the switch 20 is in the initial position, the abutting protrusion 22 on the linkage 21 is adjacent to the operating end 26 of the switch 20 relative to the guide protrusions 41 on the movable seat 40. In this embodiment, the movable seat 40 of the self-generating switch device 3 includes two guide protrusions, namely guide protrusions 41 and 41'. It should be understood that the number of guide protrusions on the movable seat 40 is not limited to this, and the number of guide protrusions can be any positive integer N, N≥1. Therefore, when the switch 20 moves relative to the housing 10 in a moving direction, the abutting protrusion 22 moves along the first side surface 411 of the guide protrusion 41 in the moving direction (as shown by the arrow L1) to the top end 413, the movable seat 40 is pressed and drives the trigger spring 31 to move away from the switch 20, the trigger spring 31 accumulates elastic force and triggers the power generation member 32 to generate a first electric signal. The switch 20 continues to be pressed and moves in the same moving direction (as shown by the arrow L1), the abutting protrusion 22 moves along the second side surface 412 from the top end 413 of the guide protrusion 41, the trigger spring 31 moves to the abutting position from the pressed position by the accumulated elastic force and abuts against one side of the movable seat 40 away from the linkage 21, so that the trigger spring 31 is restored, and the power generation member 32 generates a second electric signal. If the operating end 26 of the switch 20 is continuously pressed, the switch 20 can continue to move in the same moving direction (as shown by the arrow L1) to trigger the power generation member 32 to further accumulate two electric signals, so that the switch 20 can accumulate four electric signals in one complete pressing stroke, which further ensures that the electric power is sufficient to drive the corresponding device to operate. Figure 5 Figure 5 Figure 5

[0073] In some embodiments, the switch 20 can be other types in addition to the above-mentioned press switch. For example Figure 8 FIG. 4 shows a cross-sectional view of a fourth embodiment of the self-generating switch device 4 of the present application. This embodiment is similar to the above-mentioned Figure 3 ​​​The difference between the embodiments is at least that the switch 20A of the self-generating switch device 4 is a toggle switch. The switch 20A can be toggled by the user to move in a moving direction (as indicated by the arrow L2), so that the pressing protrusion 22A on the linkage 21A of the switch 20A can drive the movable seat 40 and the trigger spring 31 to operate, thereby triggering the generator 32 and accumulating multiple electrical signals.

[0074] Or, as Figure 9 FIG. 5 is a cross-sectional view of a fifth embodiment of the self-generating switch device 5 of the present invention. Figure 3 The difference between the embodiments is that the switch 20B of the self-generating switch device 5 is a rotary switch, and the pressing protrusion 22B is provided at one end of the linkage 21B close to the movable seat 40. The switch 20B can be manipulated by the user to rotate in a moving direction (e.g., clockwise or counterclockwise), so that the pressing protrusion 22B on the linkage 21B of the switch 20B can drive the movable seat 40 and the trigger spring 31 to actuate, thereby triggering the generator 32 and accumulating multiple electrical signals.

[0075] In summary, according to the self-generating switch device of the embodiment of the present invention, when the switch moves relative to the housing, it can drive the movable seat and the trigger spring to actuate to trigger the generator to generate an electrical signal, and the corresponding device can be driven to operate by the electrical signal. In this way, the self-generating switch device of the embodiment of the present invention does not require the installation of a battery power supply, thereby increasing its service life and being more environmentally friendly. It also does not require the installation of complex circuits to connect to the mains power, and is easy to change the setting position. In addition, the switch of the embodiment of the present invention can accumulate two electrical signals (i.e., the first electrical signal and the second electrical signal) by moving in the same direction relative to the housing, thereby ensuring that the power is sufficient to drive the operation of the corresponding device and avoiding the problem of failure of the self-generating switch device due to human operation factors.
