Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Fig. 1 is a schematic diagram illustrating a structure of a switch according to an exemplary embodiment, as shown in fig. 1, the switch includes:
at least one key body 101 for receiving key operation;
the first sensing piece is linked with the key body 101 at the corresponding position, and the key body 101 drives the first sensing piece to move when the state is switched based on the key operation;
the second sensing piece 103 is arranged opposite to the first sensing piece, in the process of the movement of the first sensing piece, the sensing parameter between the first sensing piece and the second sensing piece 103 changes, and the sensing parameter between the first sensing piece and the second sensing piece 103 is used for generating a corresponding control signal;
when the first sensing member moves to any position, the first sensing member and the second sensing member 103 are both in a non-contact state.
Note that the first sensing member is not shown in fig. 1. In some embodiments, the first sensing member may be located inside the key body 101.
The switch may include only one key body 101, or may include a plurality of key bodies 101. In the case where the switch includes a plurality of key bodies 101, the plurality of key bodies 101 may be used to control different controlled devices, and may also be used to control different functions of the same controlled device. In the case where the switch includes a plurality of key bodies 101, the plurality of key bodies 101 are independently provided on the switch surface, and there is no linkage between the plurality of key bodies 101.
The key body 101 may be located on a surface of the switch, and when a user needs to control the controlled device, the key body 101 may be subjected to a key operation, where the key operation may be an operation of pressing the key body 101. The key body 101 can receive a key operation of a user and move downward under the driving of the key operation.
The switch may include one first sensing member or a plurality of first sensing members. In the case that the switch includes a key body 101, it also includes a first sensing member; in the case that the switch includes a plurality of key bodies 101, the switch may include one first sensing member or a plurality of first sensing members.
The first sensing piece can be directly connected with the key body 101 in a bonding or clamping manner, the first sensing piece can also be indirectly connected with the key body 101 through a connecting piece of a certain type, and the first sensing piece can also not be connected with the key body 101. Here, the connection relationship between the first sensing member and the key body 101 is not limited, and only the first sensing member and the key body 101 can be linked.
In the case where the switch includes a key body 101 and a first sensing member, the first sensing member may be linked with the key body 101. When the user performs a key operation on the key body 101, the key body 101 can receive the key operation of the user, and move downward under the driving of the key operation, so as to perform state switching and drive the first sensing element to move.
In the case that the switch includes a plurality of key bodies 101 and one first sensing member, the first sensing member may be linked with the plurality of key bodies 101. When a user performs a key operation on any one of the plurality of key bodies 101, the key body 101 receiving the key operation can move downward under the driving of the key operation to perform state switching and drive the first sensing element to move. Here, the plurality of key bodies 101 do not operate at the same time, that is, the plurality of key bodies 101 do not receive the key operation at the same time.
In the case that the switch includes a plurality of key bodies 101 and a plurality of first sensing members, the number of the key bodies 101 and the first sensing members may be the same, and the setting positions in the switch may correspond one to one. Each first sensing piece can be linked with the key body 101 at the corresponding position. When a user performs a key operation on any one of the plurality of key bodies 101, one or more key bodies 101 receiving the key operation may move downward under the driving of the key operation to perform state switching and drive the first sensing element at the corresponding position to move. Here, the plurality of key bodies 101 may operate simultaneously or may not operate simultaneously, that is, the plurality of key bodies 101 may receive a key operation simultaneously or may not receive a key operation simultaneously.
The second sensing member 103 may be fixedly disposed inside the switch, and the second sensing member 103 may be disposed opposite to the first sensing member. In the process of the movement of the first sensing member, the position of the first sensing member is changed, the position of the second sensing member 103 is not changed, and the relative position of the first sensing member and the second sensing member 103 is changed, so that the sensing parameter between the first sensing member and the second sensing member 103 is changed. The sensing parameters between the first sensing element and the second sensing element 103 may include parameters such as magnetic field strength, capacitance or inductance that can change with changes in the relative positions of the first sensing element and the second sensing element 103.
It should be noted that, when the key body 101 drives the first sensing element to move to any position, the first sensing element and the second sensing element 103 are both in a non-contact state. The first sensing element and the second sensing element 103 may jointly form a non-contact switch control signal generating unit, that is, under the condition that the first sensing element is not in contact with the second sensing element 103, a control signal corresponding to a sensing parameter is generated according to the sensing parameter between the first sensing element and the second sensing element 103.
It should be noted that the control signal may be a signal for controlling the controlled device, for example, the control signal may be used to instruct to turn off the controlled device, turn on the controlled device, or adjust an operation mode of the controlled device. In the case where the controlled device includes a light fixture, the control signal may also be used to instruct adjustment of the brightness of the controlled device.
Because, key operation can drive button body 101 downstream, and then drives the activity of first response piece for the response parameter change between first response piece and the second response piece 103, therefore the response parameter between first response piece and the second response piece 103 can correspond with key operation. Meanwhile, the control signal corresponds to the sensing parameter between the first sensing member and the second sensing member 103, so that the control signal generated according to the sensing parameter between the first sensing member and the second sensing member 103 corresponds to the key operation. Furthermore, the control signal generated according to the sensing parameter between the first sensing member and the second sensing member 103 can accurately represent the control that the user wants to control the controlled device through the switch.
In this embodiment, the key body 101 can receive a key operation of a user, and move downward under the driving of the key operation. Because first response piece and the linkage of the button body 101 that corresponds the position, so can drive first response piece activity at the in-process of button body 101 downstream, and then make the response parameter between first response piece and the second response piece 103 change at the in-process that first response piece was active, then according to the response parameter generation between first response piece and the second response piece 103 with the control signal that the response parameter corresponds. Because, when the first sensing member moves to any position, the first sensing member and the second sensing member 103 are both in a non-contact state. That is, under the condition that the key body 101 drives the first sensing element to move, the first sensing element does not need to contact the second sensing element 103, and the control signal can be generated according to the sensing parameter between the first sensing element and the second sensing element 103. Therefore, the switch provided by the embodiment of the application has a simpler structure and is convenient to realize; and the abrasion in the switch is less, so that the mechanical life of the switch can be prolonged, and the sealing property and the corrosion resistance of the switch can be enhanced.
Fig. 2 is a schematic diagram of a switch according to an exemplary embodiment.
Fig. 3 is a side view of a switch according to an exemplary embodiment.
As shown in fig. 2-3, in some embodiments, the first sensing member may include: a magnetic member 1021;
the second sensing member 103 includes: a magnetic induction module 1031;
the sensing parameters include: magnetic field strength;
the magnetic part 1021 is linked with the key body 101 at the corresponding position, and the key body 101 drives the magnetic part 1021 to move in the internal space of the switch when the state is switched based on the key operation;
the magnetic induction module 1031 is configured to acquire a magnetic field strength and generate a control signal corresponding to the acquired magnetic field strength; when the magnetic member 1021 moves to different positions, the magnetic field intensity obtained by the magnetic induction module 1031 changes;
when the magnetic member 1021 moves to any position, the magnetic member 1021 and the magnetic induction module 1031 are both in a non-contact state.
Note that, the first sensing member and the magnetic member 1021 are not shown in fig. 2.
The magnetic part 1021 can be arranged inside the switch, and the magnetic part 1021 can be linked with the key body 101 at the corresponding position, so that when the key body 101 is switched based on the key operation, the magnetic part 1021 can be driven to move in the vertical direction or the horizontal direction in the internal space of the switch, the magnetic part 1021 can be driven to turn over inside the switch, and the magnetic part 1021 can be driven to move in other modes inside the switch. Here, the moving manner of the magnetic member 1021 in the switch is not limited.
In some embodiments, the magnetic induction module 1031 may be fixedly disposed at a position of the magnetic member within a magnetic field range inside the switch. It can be understood that a magnetic field exists around the magnetic member 1021, and if the magnetic induction module 1031 is disposed in the magnetic field range of the magnetic member 1021, the magnetic induction module 1031 can induce the magnetic field around the magnetic member 1021. The magnetic induction module 1031 can acquire the magnetic field strength of the induced magnetic field and generate a control signal corresponding to the acquired magnetic field strength when it induces the magnetic field around the magnetic member 1021. Because the magnetic field range of the magnetic member 1021 is also moved along with the magnetic member 1021 in the process that the magnetic member 1021 moves to different positions, the magnetic field intensity obtained by the magnetic induction module 1031 is also different in the process that the magnetic member 1021 moves to different positions, and further the control signal corresponding to the magnetic field intensity generated by the magnetic induction module 1031 is also different. Therefore, different control signals may indicate that the magnetic member 1021 moves to different positions. Meanwhile, the key operation of the user can drive the key body 101 to move, and further drive the magnetic part 1021 to move; thus, the different control signals may accurately represent the control that the user wants to control the controlled device via the switch.
For example, when the magnetic element 1021 is driven by the key body 101 to be close to the magnetic induction module 1031 (i.e. the key body 101 is pressed down to drive the magnetic element 1021 to move downward), the magnetic field intensity obtained by the magnetic induction module 1031 is relatively large, the control signal corresponding to the magnetic field intensity generated at this time may indicate that the switch is in a pressed state, and the control signal at this time may be used to instruct the controlled device to perform an operation corresponding to the switch being in the pressed state, such as instructing the controlled device to turn on or turn off.
Thus, in the embodiment of the present application, in the process that the key body 101 drives the magnetic member 1021 during the movement inside the switch, different magnetic field strengths when the magnetic member 1021 moves to different positions are obtained through the magnetic induction module 1031, and then a control signal corresponding to the magnetic field strength is generated. Because the magnetic member 1021 and the magnetic induction module 1031 are both in a non-contact state when the magnetic member 1021 moves to any position, the switch provided by the embodiment of the application is simpler in structure and convenient to implement; and the abrasion in the switch is less, so that the mechanical life of the switch can be prolonged, and the sealing property and the corrosion resistance of the switch can be enhanced.
In some embodiments, the number of the magnetic induction modules 1031, the magnetic parts 1021 and the key body 101 is the same, and the centers of the magnetic induction modules 1031, the magnetic parts 1021 and the key body 101 are located on the same axis.
In the case where the switch includes a key body 101 and a magnetic member 1021, the magnetic member 1021 may be linked with the key body 101. When a user performs a key operation on the key body 101, the key body 101 can receive the key operation of the user, and move downward under the driving of the key operation to perform state switching and drive the magnetic part 1021 to move.
In the case where the switch includes a plurality of key bodies 101 and a plurality of magnetic members 1021, the number of the key bodies 101 and the magnetic members 1021 may be the same, and the positions provided in the switch may correspond one to one. Each magnetic part 1021 can be linked with the key body 101 at the corresponding position. When a user performs a key operation on any one of the key bodies 101, the one or more key bodies 101 receiving the key operation may move downward under the driving of the key operation to perform state switching and drive the magnetic member 1021 at the corresponding position to move. Here, the plurality of key bodies 101 may operate simultaneously or may not operate simultaneously, that is, the plurality of key bodies 101 may receive a key operation simultaneously or may not receive a key operation simultaneously.
As shown in fig. 2, in some embodiments, the switch may include a bottom case 104, and the projection portions of the magnetic induction module 1031, the magnetic member 1021 and the key body 101 on the bottom case 104 are overlapped.
Thus, the magnetic induction module 1031, the magnetic part 1021 and the key body 101 can be aligned one by one at the positions inside the switch, and the magnetic field intensity of the magnetic field around the magnetic part 1021 acquired by the magnetic induction module 1031 is more accurate.
In some embodiments, the magnetic induction module 1031 may include a hall sensor for acquiring magnetic field strength and generating a control signal corresponding to the acquired magnetic field strength.
Fig. 4 is a schematic diagram of a hall sensor according to an exemplary embodiment.
Fig. 5 is a schematic diagram of a hall sensor according to an exemplary embodiment.
As shown in fig. 4-5, in some embodiments, in the case that the magnetic induction module is a hall sensor 10311, the principle that the magnetic member and the magnetic induction module cooperate to generate the control signal may be the hall effect. Hall effect: when a metal or semiconductor sheet, which is supplied with current, is placed vertically in a magnetic field, a potential difference is generated across the sheet. That is, when a magnetic field exists around the magnetic member 1021 and the hall sensor 10311 is disposed in the magnetic field range of the magnetic member 1021, the hall sensor 10311 can detect the magnetic field around the magnetic member 1021, obtain the magnetic field strength of the magnetic field around the magnetic member 1021, and generate an electrical signal corresponding to the magnetic field strength.
When the south pole of the magnetic member 1021 faces the hall sensor 10311, the magnetic field strength acquired by the hall sensor 10311 is a positive value; when the north pole of the magnetic member 1021 is oriented toward the hall sensor 10311, the magnetic field strength acquired by the hall sensor 10311 is a negative value. When the magnetic member 1021 moves, the magnetic field around the hall sensor 10311 changes, and the electric signal generated by the hall sensor 10311 according to the magnetic field intensity also differs. As the magnetic member 1021 is closer to the hall sensor 10311, the value of the magnetic field intensity acquired by the hall sensor 10311 becomes larger. When the key body is in a reset state, the distance between the magnetic part 1021 and the hall sensor 10311 is long, and the magnetic field intensity acquired by the hall sensor 10311 is smaller than the magnetic field release point B corresponding to the hall sensor 10311RPNOr BRPSWhen, the hall sensor 10311 may generate the high level VOH. When the key body is in a pressed state, the distance between the magnetic piece 1021 and the hall sensor 10311 is short, and the magnetic field intensity acquired by the hall sensor 10311 is greater than the magnetic field working point B corresponding to the hall sensor 10311OPNOr BOPSWhen the hall sensor 10311 generates the low level VOL。BRPNThe magnetic field release point corresponding to the Hall sensor 10311 when the north pole of the magnetic member 1021 faces the Hall sensor 10311, BRPSA magnetic field release point corresponding to the hall sensor 10311 when the south pole of the magnetic member 1021 faces the hall sensor 10311; b isOPNThe working point of the magnetic field corresponding to the Hall sensor 10311 when the north pole of the magnetic member 1021 faces the Hall sensor 10311, BOPSThe magnetic field operating point corresponding to the hall sensor 10311 is when the south pole of the magnetic member 1021 faces the hall sensor 10311.
Here, the electric signal (including a low level or a high level) generated by the hall sensor 10311 may be used as the control signal. In some embodiments, the switch may further comprise a processing module. After the hall sensor 10311 generates the electrical signal, the processing module may acquire the electrical signal generated by the hall sensor 10311; and determining key value information of the switch according to the electric signal generated by the hall sensor 10311, and generating a control signal according to the key value information. It is understood that the key value information may include states of the key body (the states of the key body include a reset state and a pressed state), i.e., on-off states (on-states and off-states) of the switch. Here, the on state of the switch corresponds to the pressed state of the key body, and the off state of the switch corresponds to the reset state of the key body.
Fig. 6 is a schematic diagram illustrating a structure of a circuit board according to an exemplary embodiment.
In some embodiments, as shown in fig. 2 and 6, the switch may include:
a bottom case 104;
a circuit main board 105 located on the surface of the bottom case 104 opposite to the key body 101, and the magnetic induction module 1031 is located on the circuit main board 105.
It should be noted that the bottom case 104 may be used to protect the internal structure of the switch, the key body 101 may be covered with the bottom case 104 to form an internal space, and various components of the switch (for example, the circuit board 105 and the magnetic induction module 1031) may be located in the internal space formed by covering the key body 101 and the bottom case 104.
In some application scenarios, the switch may be disposed on different support surfaces through the bottom case 104, for example, the switch may be fixedly disposed on a wall through the bottom case 104.
Like this, can close through button body 101 and bottom shell 104 lid to form a complete switch shell, can set up circuit main board 105 and magnetic induction module 1031 in button body 101 and bottom shell 104 lid and close the inner space that forms, then can receive the button operation through button body 101 like this, and through button body 101 and bottom shell 104 inside device of protection switch, like circuit main board 105 and magnetic induction module 1031.
As shown in fig. 2, in some embodiments, the switch may include:
a protection layer 106, located between the key body 101 and the magnetic induction module 1031, where a deformation space is formed between a first side of the protection layer 106 close to the magnetic induction module 1031 and the magnetic induction module 1031;
the magnetic member moves on the second side of the protection layer 106 close to the key body 101, and when the magnetic member moves to contact the protection layer 106 and the protection layer 106 is stressed, the stressed portion of the protection layer 106 deforms into the deformation space on the second side.
It can be understood that, because the deformation space is provided between the first side of the protection layer 106 close to the magnetic induction module 1031 and the magnetic induction module 1031, when the magnetic member moves to contact with the protection layer 106 and the protection layer 106 is stressed, the stressed portion of the protection layer 106 can deform into the deformation space of the second side, so that in the process of the movement of the magnetic member, the abrasion of the protection layer 106 is small.
The protection layer 106 may be made of waterproof silica gel, or may be made of other insulating and waterproof flexible materials. The structure of the protective layer 106 may correspond to a device inside the switch, the protective layer 106 may be attached to the device inside the switch, and when a certain device inside the switch has a convex portion, a position on the protective layer 106 corresponding to the convex portion of the device also has a convex structure; when a device inside the switch has a concave portion, the position of the protective layer 106 corresponding to the concave portion of the device also has a concave structure.
As shown in fig. 2, in some embodiments, the switch may include: the key comprises a key body 101, a middle cover 112, a protective layer 106, a transmission part 110, a circuit main board 105 and a bottom shell 104; the key body 101, the middle cover 112, the protective layer 106, the transmission member 110, the circuit board 105, and the bottom case 104 are stacked. The side of the protective layer 106 opposite to the middle cover 112 is attached to the middle cover 112, and the side of the protective layer 106 opposite to the transmission component 110 is attached to the transmission component 106. For example, in the case where the transmission member 110 has a convex portion, a position on the protective layer 106 corresponding to the convex portion of the transmission member 110 also has a convex structure.
Fig. 7 is a schematic structural diagram illustrating a key body according to an exemplary embodiment.
As shown in fig. 3 and fig. 7, in some embodiments, the magnetic member 1021 may be located on a surface of the key body 101 opposite to the magnetic induction module 1031, and the magnetic member 1021 is located in an induction range of the magnetic induction module 1031 at least when the key body 101 is in a pressed state.
The magnetic member 1021 can be directly disposed on the surface of the key body 101 opposite to the magnetic induction module 1031 by bonding or clipping. Thus, the linkage of the magnetic part 1021 and the key body 101 can be realized, and the internal structure of the switch can be simpler and easier to realize.
The magnetic element 1021 is located in the sensing range of the magnetic induction module 1031 at least when the key body 101 is in the pressed state, that is, the magnetic induction module 1031 can sense the magnetic field around the magnetic element 1021 at least when the key body 101 is in the pressed state. In this way, the magnetic induction module 1031 can obtain the magnetic field strength within the induction range at least when the key body 101 is in the pressed state, and further generate a control signal corresponding to the magnetic field strength.
When the key body 101 is in the reset state, the magnetic member 1021 may be located within the sensing range of the magnetic induction module 1031, or may not be located within the magnetic induction range of the magnetic induction module 1031. When the key body 101 is in the reset state and the magnetic member 1021 is not located within the magnetic induction range of the magnetic induction module 1031, the magnetic field strength acquired by the magnetic induction module 1031 may be zero. Here, it is only necessary to ensure that the magnetic induction module 1031 acquires different magnetic field strengths when the key body 101 is in the pressed state and the reset state (including the case where the acquired magnetic field strength is zero).
As shown in fig. 3, in some embodiments, the switch comprises:
a first protruding portion 107 located on a surface of the key body 101 opposite to the magnetic induction module 1031;
an accommodating space is arranged in the first protruding part 107, and the magnetic part 1021 is positioned in the accommodating space;
the first protruding portion 107 and the key body 101 are integrally formed, or the first protruding portion 107 and the key body 101 are fixedly connected.
Because the first protruding portion 107 is located on the surface of the key body 101 opposite to the magnetic induction module 1031, when the key body 101 switches states, the first protruding portion 101 can move along with the key body 101, so as to drive the magnetic member 1021 in the first protruding portion 107 to move.
Like this, through in setting up magnetic part 1021 in the accommodation space in first bellying 107, can reduce the distance of magnetic part 1021 and magnetism induction module 1031 for magnetism induction module 1031 can more accurately sense the magnetic field around magnetic part 1021, acquires more accurate magnetic field intensity, thereby makes the control signal that corresponds with magnetic field intensity that generates more accurate.
In some embodiments, the switch may be a self-generating switch.
As shown in fig. 3, in some embodiments, the switch may include:
a processing module;
and the power supply module 109 is connected with the magnetic induction module 1031 and the processing module, and is used for converting kinetic energy generated by the key body 101 during state switching into electric energy and supplying power to the magnetic induction module 1031 and the processing module.
Here, the power supply module 109 inside the switch can generate power and supply power to the devices inside the switch, and the switch can be disposed at any position without connecting the switch to other power lines. Therefore, the switch provided by the embodiment of the application is environment-friendly and can be applied to more scenes.
It should be noted that, the processing module is not shown in fig. 3, and the processing module may be disposed inside the switch.
As shown in fig. 2, in some embodiments, the switch may further include: the transmission component 110 is used for transmitting the kinetic energy generated when the key body 101 is switched to the power supply module 109.
The first protrusion can also be used to cooperate with the transmission component 110 to transmit the kinetic energy generated by the key body 101 during state switching to the power supply module 109. That is, under the condition that the key body 101 is pressed down, the key body 101 drives the first protrusion to move, so that the first protrusion contacts with the transmission part 110 and drives the transmission part 110 to move, the kinetic energy generated when the key body 101 is switched to the state is transmitted to the transmission part 110, and then the transmission part transmits the kinetic energy to the power supply module 109.
Here, the first protruding portion can be used to provide an installation foundation for the magnetic part 1021 and drive the magnetic part 1021 to move, and can also be matched with the transmission part 110 to transmit kinetic energy generated when the state of the key body 101 is switched to the power supply module 109, so that two functions can be simultaneously realized only through the first protruding portion. Therefore, the structure of the switch provided by the embodiment of the application can be simpler.
Fig. 8 is a schematic diagram illustrating a detection timing sequence of a magnetic induction module according to an exemplary embodiment.
As shown in fig. 8, the detection period of the magnetic induction module includes a working period and a waiting period, in one detection period, the magnetic induction module performs magnetic field detection in the working period and outputs a detection result, then maintains a waiting state in the waiting period until the next detection period starts, and performs the next magnetic field detection in the working period in the next detection period and updates the detection result. That is, when the magnetic induction module changes in the state of the surrounding magnetic field, the output state of the magnetic induction module can be updated only after the next detection period. It can be understood that, in order to generate the control signal accurately enough, it is necessary to ensure that the magnetic field is detected accurately and reliably in the first detection period when the magnetic induction module is powered on. As long as stable power supply is maintained before the first detection period of power-up of the magnetic induction module (before the working period in fig. 8), it can be ensured that the first detection period of the magnetic induction module detects the magnetic field accurately and reliably. Therefore, the magnetic induction module can be powered on under the condition of stable power supply.
Fig. 9 is a block diagram illustrating a switch according to an exemplary embodiment. Note that, the key body and the magnetic member are not shown in fig. 9.
As shown in fig. 9, in some embodiments, the switch comprises:
the voltage stabilizing module 111 is connected to the power supply module 109, the processing module 108 and the magnetic induction module 1031, and is configured to adjust the electric energy output by the power supply module 109 and input the adjusted electric energy into the processing module 108;
the processing module 108 is connected to the voltage stabilizing module 111, and configured to receive the electric energy output by the voltage stabilizing module 111, and after it is determined that the voltage stabilizing module 111 enters a preset working state, control the voltage stabilizing module 111 to supply power to the magnetic induction module 1031.
The preset operating state may be a steady state, i.e., a state after the voltage stabilizing module 111 is completely started up. Here, it should be noted that, during the process that the voltage regulator 111 supplies power to the magnetic induction module 1031, the current at the moment of powering on the magnetic induction module 1031 is large, and at this moment, if the voltage regulator 111 does not enter the preset operating state, the large current at the moment of powering on the magnetic induction module 1031 may cause the voltage regulator 111 to reset.
Here, after determining that the voltage stabilizing module 111 enters the preset operating state, the processing module 108 controls the voltage stabilizing module 111 to supply power to the magnetic induction module 1031, so that the situation that the voltage stabilizing device 111 is reset due to a large current at the moment of power-on of the magnetic induction module 1031 can be avoided to a certain extent.
In some embodiments, the processing module 108, the power supply module 109, the voltage stabilizing module 111, and the magnetic induction module 1031 may be located on the circuit board 105 shown in fig. 2.
As shown in fig. 2, in some embodiments, the switch may further include:
a middle cover 112 disposed in parallel between the key body 101 and the magnetic induction module 1031;
the middle cover comprises: a through hole 1121;
the magnetic member is located on the middle cover 112, and at least a portion of the magnetic member extends into the aperture range of the through hole 1121;
the key body 101 includes:
and when the state of the key body 101 is switched, the second protruding part is in contact with or separated from at least part of the magnetic part, so as to drive the magnetic part to move in the internal space of the switch.
Note that the magnetic member and the second projecting portion are not shown in fig. 2.
Well lid 112 can be waterproof material, and well lid 112 can play waterproof effect on the one hand, and on the other hand can the inside various devices of fixed switch, for example, well lid 112, parallel arrangement can be used for fixed magnetic induction module 1031 between button body 101 and magnetic induction module 1031, avoids to a certain extent, and the activity of button body 101 is to magnetic induction module 1031's influence. In this embodiment, the middle cap 112 may also provide a mounting base for the magnetic member.
Middle cap 112 may have a thickness, and the thickness of middle cap 112 may be set as the case may be. The through hole 1121 of the middle cap 112 may provide a moving space for the magnetic member, and the magnetic member may move in the through hole 1121. It should be noted that, in some embodiments, the magnetic member may also be movable outside the through hole 1121, such as in a space between the magnetic member and the middle cover 112 or in a space between the middle cover 112 and the magnetic induction module 1031.
The second protruding portion can move together with the key body 101 when the key body 101 receives a key operation to perform state switching. The second protrusion can further drive the magnetic member to move in the internal space of the switch during the moving process, where the internal space of the switch includes the through hole 1121.
Here, by providing the magnetic member on the middle cover 112, the distance between the magnetic member and the magnetic induction module 1031 can be made smaller, so that the magnetic field strength of the magnetic field around the magnetic member acquired by the magnetic induction module 1031 is more accurate.
Fig. 10 is a schematic diagram of a side structure of a switch according to an exemplary embodiment.
Fig. 11 is a schematic diagram showing a side structure of a switch according to an exemplary embodiment.
As shown in fig. 10-11, in some embodiments, the magnetic member 1021 may be connected to the middle cover 112 via a movable member 113;
the second protrusion 1011 is located on a surface of the key body 101 opposite to the middle cover 112, and when the key body 101 is switched between states, the second protrusion 1011 contacts or separates from at least a portion of the magnetic member 1021, and the magnetic member 1021 is driven by the moving member 113 to move along a hole depth direction of the through hole 1121 in an inner space corresponding to an aperture range of the through hole 1121.
It is understood that fig. 10 may be a schematic side view of the switch when the key body 101 is in the reset state, and fig. 11 may be a schematic side view of the switch when the key body 101 is in the pressed state. When the key body 101 is switched from the reset state shown in fig. 7 to the pressed state shown in fig. 8, the magnetic member 1021 can approach the magnetic induction module 1031 along the hole depth direction of the through hole 1121.
When the key body 101 is in the reset state shown in fig. 10, the magnetic field strength acquired by the magnetic induction module 1031 may be B1, the control signal generated by the magnetic induction module 1031 and corresponding to B1 may be a first control signal, and the first control signal may indicate that the controlled device is turned off; when the key body 101 is in the pressed state shown in fig. 11, the magnetic field strength acquired by the magnetic induction modules 1031 may be B2, the control signal generated by the magnetic induction modules 1031 and corresponding to B2 may be a second control signal, and the second control signal may indicate that the controlled device is turned on. Since the closer the magnetic member 1021 is to the magnetic induction module 1031, the greater the magnetic field intensity acquired by the magnetic induction module 1031, B2 may be greater than B1.
Here, the magnetic member 1021 can move in the inner space corresponding to the aperture range of the through hole 1121 along the hole depth direction of the through hole 1121; therefore, there is less medium between the magnetic member 1021 and the magnetic induction module 1031, and in the case that the switch does not include the protection layer 106, the medium between the magnetic member 1021 and the magnetic induction module 1031 is air. Therefore, the magnetic field intensity around the magnetic member 1021 acquired by the magnetic induction module 1031 can be further accurate.
Fig. 12 is a side view of a switch according to an exemplary embodiment.
Fig. 13 is a side view schematic diagram five of a switch according to an exemplary embodiment.
As shown in fig. 12-13, in some embodiments, the middle cap 112 may include:
the two ends of the turning shaft 1122 are respectively movably connected with the hole wall of the through hole 1121;
the magnetic part 1021 is positioned on the turning shaft 1122 and is positioned in the aperture range of the through hole 1121;
when the key body 101 is switched between states, the second protrusion 1011 is in contact with or separated from at least a portion of the magnetic member 1021, and the magnetic member 1021 is driven to turn over in the internal space of the switch corresponding to the aperture range of the through hole 1121 through the turning shaft 1122.
In some embodiments, the second protrusion 1011 may be separated from the magnetic member 1021 immediately after contacting the magnetic member 1021 and driving the magnetic member 1021 to flip, that is, the key body 101 may be reset immediately after being pressed down, so that the second protrusion 1011 is separated from the magnetic member 1021.
It is understood that fig. 12 may be a schematic side structure view of the switch before the magnetic member 1021 is turned over, and fig. 13 may be a schematic side structure view of the switch after the magnetic member 1021 is turned over. Before and after the magnetic member 1021 is reversed, the magnetic member 1021 has different polarity towards the magnetic induction module 1031, and the magnetic field intensity obtained by the magnetic induction module 1031 has the same magnitude and opposite direction. For example, before the magnetic member 1021 turns over, the magnetic field intensity acquired by the magnetic induction module 1031 may be a positive value, and after the magnetic member 1021 turns over, the magnetic field intensity acquired by the magnetic induction module 1031 may be a negative value. Therefore, when the magnetic member 1021 moves to different positions, the magnetic induction module 1031 acquires different magnetic field strengths. Furthermore, the magnetic induction module 1031 may generate different control signals according to the acquired different magnetic field strengths.
Since the space required for turning the magnetic member 1021 is small, the magnetic member 1021 is provided on the turning shaft 1122 of the middle cap 112. The internal structure of the switch provided by the embodiment of the application can be more compact.
Fig. 14 is a side view of a switch according to an exemplary embodiment.
Fig. 15 is a side view diagram seven of a switch according to an exemplary embodiment.
As shown in fig. 14-15, in some embodiments, the key body 101 may include:
a third protrusion 1012 located on a surface of the key body 101 opposite to the middle cover 112 of the switch;
the magnetic part 1021 is movably connected with the middle cover 112 of the switch, and when the key body 101 is switched from the reset state to the pressed state, the third protrusion 1012 pushes the magnetic part 1021 to move towards the first direction;
the middle cap 112 may include:
the reset piece 1123, during the process of switching the key body 101 from the pressed state to the reset state, the reset piece 1123 pushes the magnetic piece 1021 to move along the second direction; the first direction and the second direction are different.
Here, the magnetic member 1021 may be movably connected with the reset member 1123 of the middle cap 112.
It is understood that fig. 14 may be a schematic side view of the switch when the key body 101 is in the reset state, and fig. 15 may be a schematic side view of the switch when the key body 101 is in the pressed state. For example, in fig. 14-15, during the process of switching the key body 101 from the reset state to the pressed state, the third protrusion 1012 pushes the magnetic member 1021 to move leftward (first direction); during the process of switching the key body 101 from the pressed state to the reset state, the reset piece 1123 pushes the magnetic piece 1021 to move rightward (in the second direction). It can be understood that after the state of the key body 101 is switched, the relative position between the magnetic member 1021 and the magnetic induction module 1031 changes, and the magnetic field strength obtained by the magnetic induction module 1031 also changes, for example, in fig. 14, the magnetic member 1021 is located right above the magnetic induction module 1031, and the magnetic field strength obtained by the magnetic induction module 1031 may be B3; after the key body 101 is switched, in fig. 15, the magnetic member 1021 is located at the upper left of the magnetic induction module 1031, the magnetic field strength acquired by the magnetic induction module 1031 may be B4, and B3 may not be equal to B4. Therefore, a through hole does not need to be formed in the middle cover 112, the structure of the middle cover 112 is incomplete, and the water resistance of the whole switch is better.
Fig. 16 is a block diagram of a switch according to an exemplary embodiment.
As shown in fig. 16, in some embodiments, based on fig. 9, the switch may further include a rectifying module 114, an energy storage module 115, a communication module 116, and an indicator light module 117.
The rectifying module 114 is connected with the power supply module 109 and is used for converting electric energy generated by the power supply module from alternating current to direct current;
the energy storage module 115 is connected with the rectifying module 114 and the voltage stabilizing module 111 and is used for storing the direct current;
the voltage stabilizing module 111 is connected with the processing module 108 and the magnetic induction module 1031, and is used for adjusting the electric energy output by the energy storage module 115 and inputting the adjusted electric energy into the processing module 108 and the magnetic induction module 1031;
a magnetic induction module 1031 for acquiring magnetic field intensity in an internal space of the switch and generating a control signal corresponding to the acquired magnetic field intensity;
a communication module 116 for transmitting a control signal to a controlled device;
the processing module 108 is connected with the magnetic induction module 1031, the communication module 116 and the indicator light module 117, and is used for controlling the voltage stabilizing module 111 to supply power to the magnetic induction module 1031; the magnetic induction module 1031 is further configured to obtain a control signal generated by the magnetic induction module 116, and control the communication module 116 to transmit the control signal to the controlled device; and is also used for controlling the indicator light module 117 to turn on or off according to the control signal.
Here, the indicator module 117 may be located on an inner surface of the key body, and when the key body is in a pressed state, the processing module 108 controls the indicator module 117 to light up and emit light through the key body.
Fig. 17 is a side view diagram eight illustrating a switch according to an exemplary embodiment.
As shown in fig. 17, in some embodiments, the first sensing member includes: a first metal sheet 1022;
the second sensing member includes: a second metal sheet 1032;
the sensing parameters include: a capacitance value;
with both the first and second metal sheets 1022, 1032 energized, the first metal sheet 1022 couples with the second metal sheet 1032 to form a capacitor; when the first metal sheet 1022 moves to different positions, the capacitance value of the capacitor changes;
when the first metal sheet 1022 moves to any position, both the first metal sheet 1022 and the second metal sheet 1032 are in a non-contact state.
The first metal sheet 1022 may be disposed inside the switch, and the first metal sheet 1022 may be linked with the key body 101 at a corresponding position, so that when the key body 101 switches states based on key operations, the first metal sheet 1022 may be driven to move in the same direction as the key operations in the internal space of the switch. The second metal plate 1032 may be fixedly disposed at a position opposite to the first metal plate 1022 inside the switch, and when the first metal plate 1022 moves to a different position, a distance between the first metal plate 1022 and the second metal plate 1032 changes, so that a capacitance value of a capacitor formed by coupling the first metal plate 1022 and the second metal plate 1032 changes.
In some embodiments, the processing module may be further configured to obtain a capacitance value of a capacitor formed by coupling the first metal sheet 1022 and the second metal sheet 1032, and generate a control signal corresponding to the obtained capacitance value according to the obtained capacitance value.
Here, when the first metal sheet 1022 moves to any position, the first metal sheet 1022 and the second metal sheet 1032 are both in a non-contact state, so the structure of the switch provided by the embodiment of the present application is simpler and is convenient to implement; and the abrasion in the switch is less, so that the mechanical life of the switch can be prolonged, and the sealing property and the corrosion resistance of the switch can be enhanced.
In some embodiments of the present invention, the,
the first metal sheet 1022 is located on a surface of the key body 101 opposite to the second metal sheet 1032.
In this embodiment, the position of the first metal sheet 1022 may refer to the position of the magnetic member 1021 in fig. 5.
The first metal sheet 1022 may be directly disposed on the surface of the key body 101 opposite to the second metal sheet 1032 by means of adhesion or clipping. Thus, the first metal sheet 1022 and the key body 101 can be linked, and the internal structure of the switch can be simpler and easier to implement.
In some embodiments, a protective layer and a middle cover may also be disposed between the key body 101 and the second metal sheet 1032.
