The invention relates to a switch structure, and particularly relates to a switch structure of a power line device.
2. Related Art
A general local area network (LAN) in home can be a wired Ethernet LAN, a wired IEEE 802.11x LAN, or a home plug constructed by using power lines laid in home. The home plug is a communication network constructed by using the power lines already existing in home based on a power line communication (PLC) technique, and a user is only required to connect the home plug to an alternating current (AC) power outlet installed in home, or the home plug can be preinstalled in a house power line system during construction or decoration of the house, and then the user can use the power line to access the Internet without additionally installing a network line, so as to achieve a purpose of LAN communication and network resource sharing.
However, an existing switch structure used for activating the home plug is limited to a following situation: the power is first supplied to the switch to activate an electromagnetic valve therein, and the electromagnetic valve pushes electrodes to contact each other or separate from each other, and once supply of the power is stopped, the electromagnetic valve is accordingly turned off, so that the power has to be continuously provided in order to keep activating the home plug, and energy saving cannot be effectively achieved.
The invention is directed to a switch structure, in which two moving members are used to achieve a turning on/off effect of the switch structure in a power saving mode.
The invention provides a switch structure including a first electrode, a first moving member, a second electrode and a second moving member. The first moving member is movably disposed next to the first electrode along a first axis. The first moving member has a first tenon unit. The second electrode is disposed at one end of the first moving member and faces the first electrode. The second moving member is movably disposed next to the first moving member along a second axis. The second moving member has a second tenon unit. The first axis is orthogonal to the second axis. When the first moving member moves to a first position and the second moving member moves to a second position, the first tenon unit and the second tenon unit are interfered with each other, and the first electrode is electrically connected to the second electrode. When the second moving member moves to a third position, the first moving member moves along the first axis and passes by the second moving member.
In an embodiment of the invention, the switch structure includes a first electromagnetic valve unit and a second electromagnetic valve unit. The first electromagnetic valve unit has a first coil, a first power supply and the first moving member. The first moving member is sleeved by the first coil, and the first power supply is electrically connected to the first coil. The second electromagnetic valve unit has a second coil, a second power supply and the second moving member. The second moving member is sleeved by the second coil, and the second power supply is electrically connected to the second coil.
In an embodiment of the invention, the first tenon unit includes a first block and a first groove arranged along the first axis. The second tenon unit includes a second block and a second groove arranged along the second axis. When the first moving member moves to the first position, and the second moving member moves to the second position, the second block moves to the first groove to interfere with the first block, such that the second moving member stops the first moving member to move along the first axis. When the second moving member moves to the third position, the first moving member moves along the first axis and passes by the second groove.
In an embodiment of the invention, the switch structure further includes a substrate and an elastic member. The substrate is located at one side of the first moving member along the first axis. The elastic member is connected between the substrate and another end of the first moving member relative to the second electrode. The elastic member keeps driving the first moving member to depart from the first position.
In an embodiment of the invention, the switch structure further includes a substrate and an elastic member. The substrate is located at one side of the first moving member along the first axis. The elastic member is connected between the substrate and another end of the first moving member relative to the second electrode. The elastic member keeps driving the first moving member to move to the first position.
In an embodiment of the invention, the switch structure further includes a third electrode and a fourth electrode. The third electrode is disposed relative to the first electrode along the first axis. The fourth electrode is disposed on the first moving member at another end relative to the second electrode. The fourth electrode faces the third electrode. When the first moving member moves to the first position, and the second moving member moves to the second position, the third electrode is away from the fourth electrode. When the first moving member moves to a fourth position, the third electrode is electrically connected to the fourth electrode, and the first electrode is away from the second electrode.
In an embodiment of the invention, the first tenon unit includes a first block, a first groove and a third groove arranged along the first axis. The second tenon unit includes a second block and a second groove arranged along the second axis. When the first moving member moves to the first position, and the second moving member moves to the second position, the second block moves to the first groove to interfere with the first block, or when the first moving member moves to a fourth position, and the second moving member moves to the second position, the second block moves to the third groove to interfere with the first block, such that the second moving member stops the first moving member to move along the first axis.
In an embodiment of the invention, the first block is located between the first groove and the third groove.
According to the above descriptions, based on orthogonal configuration of the two moving members of the switch structure and the tenon units disposed thereon, the electrode disposed on the first moving member is adapted to be electrically connected to or separate from the corresponding electrode along with movement of the first moving member, and meanwhile the second moving member is buckled to the first moving member located at the above position by using the tenon unit, such that the first moving member is fixed to an electrode connection position. Even if the power is not supplied, the electrodes still maintain an electrical connection relationship due to fixing of the first moving member, i.e., the switch structure is still in a turn-on state. In this way, the switch structure is unnecessary to keep providing power to maintain the first moving member to the electrode connection position, so as to achieve a power saving effect.
In order to make the aforementioned and other features and advantages of the invention comprehensible, several exemplary embodiments accompanied with figures are described in detail below.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Since power lines are widely used and a coverage rate thereof is the most extensive, if the existing power lines can be used to extend network to each corner of user's house (i.e., to use a power line outlet to conveniently access the network), a huge cost for re-laying network lines is saved, and a problem of cross-floor or a wall shielding problem due to usage of wireless communication is also avoided. Therefore, technical standards for power line communication (PLC), for example, HomePlug 1.0, etc. have been developed and applied to related electronic devices.
In the present embodiment, the power line device 100 can be an electronic component directly installed to a home plug, i.e., the power line device 100 can be installed during construction or decoration of a building, i.e., the circuit substrate 130 is preinstalled to a power line 300, and is regarded as one of a plurality of contacts of the whole power line in the building. On the other hand, in an embodiment that is not illustrated, the power line device can also be an external electronic component, which can be connected to a power outlet in house through a power terminal, so as achieve the same effect. Therefore, a usage pattern of the power line device is not limited by the invention.
Referring to
According to the above description, the first moving member 126a and the second moving member 128a can be respectively controlled by the first coil 126b (and the first power supply 126c) and the second coil 128b (and the second power supply 128c) based on an electromagnetic effect, such that the first moving member 126a moves along the Z-axis, and the second moving member 128a moves along an X-axis. Moreover, as shown in
In
According to the above descriptions, referring to
Therefore, in the present embodiment, by using the second moving member 128a, in the aforementioned status, the second power supply 128c and the second coil 128b can drive the second moving member 128a to move to a position P2 (from the position P3), such that the groove A22 of the second moving member 128a is moved away from the moving path of the first moving member 126a (along the Z-axis), and the block A21 is moved to the moving path of the first moving member 126a. Therefore, the block A11 of the first tenon unit A1 is interfered with the block A21 of the second tenon unit A2, and the second moving member 128a stops the first moving member 126a to move towards a negative Z-axis direction. In this way, the first moving member 126a and the second moving member 128a are structurally interfered, and now even if the first power supply 126c stops supplying power to the first coil 126b, the first moving member 126a can still be maintained to the position P1 to maintain the electrical connection relationship between the first electrode 122 and the second electrode 124, and the communication unit 110 is maintained to a turn-on state.
It should be noticed that since the first moving member 126a and the second moving member 128a are substantially orthogonal structures (with orthogonal moving paths), in case that the first moving member 126a presents a longitudinal layout and movement, the second moving member 128a presents a latitudinal layout and movement (the aforementioned orientation is based on a viewing angle shown in the figures). In this way, under a premise of none other external force, the second moving member 128a is only controlled by the second coil 128b and the second power supply 128c to move, so as to achieve an effect of blocking or releasing the first moving member 126a. According to the above descriptions, once the communication unit 110 is required to be turned off, it is only required to drive the second moving member 128a to move along the X-axis, and the groove A22 is moved back to the moving path of the first moving member 126a, such that the first moving member 126a can move towards the negative Z-axis direction to restore its original position.
When the first moving member 126a is controlled by the first coil 126b and the first power supply 126c (referring to
Comparatively, when the first moving member 126 is controlled by the first coil 126b and the first power supply 126c (referring to
In an embodiment that is not illustrated, moving components capable of moving oppositely relative to each other can be configured between the electronic units 210 and 310 to replace the first moving members 126a. In other words, the moving components can be controlled by a magnetic force to move towards the positive Z-axis direction and the negative Z-axis direction through related mechanism parts (for example, a screw having reverse threads, gears, etc.), such that the moving components can simultaneously turn on/off the electronic units 210 and 310 in a two-way moving mode. Similarly, by using the aforementioned first tenon unit A1 and the second tenon unit A2, the second moving member 128a can be interfered with the moving components, such that the moving components can maintain an electrical connection state or a disconnection state between the electrodes 221 to 224 due to the interference in case that the moving components are not driven by the magnetic force.
In summary, in the switch structure of the power line device, based on the moving members having orthogonal configuration and orthogonal movement, while the first moving member is moved to connect or disconnect the electrodes, the second moving member can be interfered with the first moving member, such that the first electromagnetic valve unit can be still maintained to a position suitable for turning on the communication unit due to the structural interference in case that the first electromagnetic valve unit is not supplied with power, and the communication unit is maintained to a turn-on state to avoid a risk of being turned off due to power-off. In other words, the power line device of the invention can achieve the required communication function without being kept in a power-on state, such that the power line device may have a better power saving effect by using the aforementioned switch structure.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
