FIGS. 1-9 show an electronic apparatus of the present disclosure, and the electronic apparatus includes a base, a sliding member and a sliding mechanism 80. The sliding mechanism 80 drives the sliding member to slide among different locations of the base.
FIGS. 1-6 c show that a power supply socket 1 is taken as an example of the electronic apparatus. The power supply socket 1 includes a housing 60, at least one cover 70 and at least one sliding mechanism 80 corresponding to the at least one cover 70, the housing 60 is defined as the base, and the cover 70 is defined as the sliding member. The at least one cover 70 can slide from one location of the housing 60 to another location of the housing 60 driven by the at least one sliding mechanism 80, such as to slide between a first predetermined location of the housing 60 and a second predetermined location of the housing 60.
In the embodiment, as shown in FIGS. 1 and 2, the power supply socket 1 includes a power cable 50 extending out of the housing 60 from a side of the housing 60. A plug (not shown) is disposed at one end of the power cable 50 away from the housing 60, to be able to connect with an external power supply. The housing 60 defines at least one receiving room 620 with a pair of power outlets 610 defined at the bottom of each receiving room 620. FIG. 1 shows a non-working state of the power supply socket 1 when each cover 70 is driven by the sliding mechanism 80 to cover a corresponding pair of power outlets 610 to prevent water and dust from entering into the power supply socket 1, thereby avoiding the occurrence of electrical accidents. FIG. 2 shows a working state of the power supply socket 1 when each cover 70 slides away driven by the sliding mechanism 80, to expose the corresponding pair of power outlets 610, to facilitate a user to use.
FIG. 3 shows an exploded view of the power supply socket 1 of FIG. 2. In the embodiment, the housing 60 is rectangular shaped, and defines an internal receiving space (not shown) for receiving electronic components, such as a circuit board. In one embodiment, the at least one receiving room 620 extends downward from a top surface of the housing 60, the number of the receiving rooms 620 is three, and the three receiving rooms 620 have the same dimensions and are arranged along the longitudinal direction of the housing 60. The number of the cover 70 is three corresponding to the three receiving rooms 620. Each receiving room 620 may receive one cover 70 and one sliding mechanism 80 correspondingly, and each cover 70 can slide within a corresponding receiving room 620 between different locations driven by a corresponding sliding mechanism 80, respectively. In other embodiments, the number of the receiving room 620 is one. At least two pairs of power outlets 610 are disposed at the bottom of the receiving room 620 and parallel to each other. The receiving room 620 receives at least two covers 70 and at least two sliding mechanisms 80 corresponding to the at least two pairs of power outlets 610.
Each receiving room 620 is a cuboid shaped hole and includes two opposite first sidewalls 620 a, two opposite second sidewalls 620 b, and a first room 620 c and a second room 620 d surrounded by the first sidewalls 620 a and the second sidewalls 620 b. The two first sidewalls 620 a are perpendicular to the longitudinal direction of the housing 60, the two second sidewalls 620 b are perpendicular to the two first sidewalls 620 a. The second room 620 d extends downward from the first room 620 c to communicate with the first room 620 c with a connecting surface 620 e. The connecting surface 620 e is disposed in the middle of each receiving room 620, which is parallel to the second sidewalls 620 b and communicates with the two first sidewalls 620 a. Each pair of power outlets 610 is disposed at the bottom of the first room 620 c of one receiving room 620. It is understood that, in other embodiments, the first room 620 c and the second room 620 d can be arranged on a same plane, and the two first sidewalls 620 a may be parallel to or form an angle with the longitudinal direction of the housing 60.
Two receiving grooves 630 are defined in the second sidewalls 620 b. In other embodiments, the two receiving grooves 630 can be defined at two opposite bottom ends of each receiving room 620, and parallel to the sliding direction of the cover 70. In the embodiment, each sliding mechanism 80 includes a first electromagnet 84 a received in a corresponding receiving groove 630 adjacent to the power outlets 610. A switch 640 is disposed at an exterior surface of the housing 60 adjacent to the receiving rooms 620, which is configured to power on or power off the power supply socket 1 by pressing the switch 640.
In the embodiment, each cover 70 is cube-shaped, and is slidably received in a corresponding receiving room 620. The length of each cover 70 is less than that of the first sidewall 620 a of the corresponding receiving room 620. Thus, under driven of the corresponding sliding mechanism 80, the cover 70 is capable of moving along a direction parallel to the first sidewall 620 a and can slide back and forth between the first room 620 c and the second room 620 d in the receiving room 620, to alternatively cover and expose the power outlets 610. Thus, the power supply socket 1 is switched between the non-working state and the working state.
Two sidewalls (not labeled) of each cover 70 defines two cuboid notches 710 corresponding to the two receiving grooves 630. In other embodiments, the two notches 710 are disposed on a bottom surface of each cover 70 relative to the housing 60 when the two receiving grooves 630 are defined at the two opposite bottom ends of the receiving room 620. In this embodiment, each sliding mechanism 80 further includes a first magnet 82 a received in a corresponding notch 710 relative to the first electromagnet 84 a. Additionally, a sliding groove 730 is defined on the bottom surface of each cover 70, so that the cover 70 can slide stably in the receiving room 620.
FIG. 4 shows a structure diagram of the first electromagnet 84 a. In the embodiment, the first electromagnet 84 a includes a first iron core 842 a and a first coil 844 a wound around the first iron core 842 a. The first iron core 842 a is bar-shaped, the first coil 844 a is a solenoid, and a permanent magnet is capable of attracting the first iron core 842 a. Otherwise, when the first coil 844 a is to be energized, a predetermined voltage is applied to the first coil 844 a to produce a directional current. The first iron core 842 a can be made temporarily magnetic to become a magnet by the first coil 844 a and has a corresponding magnetic polarity. Then, a North pole (N pole) and an South pole (S pole) of the first iron core 842 a can be determined according to Ampere's Right Hand Rule. When the voltage of the first coil 844 a disappears, the first iron core 842 a is de-magnetized to be back to an iron and has no magnetism.
The Ampere's Right Hand Rule is that, when holding a solenoid with the right hand of a user, and bending four fingers of the user with the same direction as the current of the solenoid, the direction of the thumb pointing to is a N pole of the solenoid.
FIGS. 5 a-5 b show schematic diagrams with different states of the cover 70 changed under a force produced between the first magnet 82 a and the first electromagnet 84 a. In this embodiment, the first magnet 82 a is a permanent magnet. The power supply socket 1 further includes a reserve power source 40 (shown in FIG. 3) to supply power to the first electromagnet 84 a when the power supply socket 1 is powered off. FIG. 5 a shows an initial state of the power supply socket 1 when the cover 70 covers the power outlets 610. At this time, the first electromagnet 84 a is in its initial state having no magnetism, and one end of the first magnet 82 a adjacent to the first electromagnet 84 ais a S pole, the other end is a N pole. Since an attractive force exists between an iron and a permanent magnet, the first iron core 842 a is capable of attracting the first magnet 82 a, driving the cover 70 to slide to resist a corresponding second sidewall 620 b of the housing 60 adjacent to the first electromagnet 84 a. In addition, the cover 70 is latched within the first room 620 c of the housing 60, covering the power outlets 610 defined in the first room 620 c.
When the switch 640 is pressed to power on the power supply socket 1 to energize the first coil 844 a to produce a current I, the first iron core 842 a becomes a magnet. According to the Ampere's Right Hand Rule, the first iron core 842 a acquires a contrary magnetic polarity with the first magnet 82 a, and one end of the magnetized first iron core 842 a adjacent to the first magnet 82 a is magnetized to be determined as a S pole. The first magnet 82 a and the first electromagnet 84 a repulse each other and produce a first repulsive force to drive the cover 70 to move away from the first iron core 842 a. The cover 70 slides to the state shown in FIG. 5 b from the first room 620 c to the second room 620 d under the first repulsive force, and at this time the location of the housing 60 is defined as the first predetermined location of the housing 60.
FIG. 5 b shows the working state of the power supply socket 1 when the cover 70 does not cover the power outlets 610. At this time, the first electromagnet 84 a is magnetized, and the end of the first electromagnet 84 a adjacent to the first magnet 82 a is a S pole. The cover 70 resists another second sidewall 620 b and is latched in the second room 620 d of the housing 60 under the first repulsive force of the first magnet 82 a and the first electromagnet 84 a.
Then, when the switch 640 is pressed again to power off the power supply socket 1 to de-energize the first coil 844 a, the first iron core 842 a is de-magnetized and back to be an iron, the first repulsive force between the first magnet 82 a and the first electromagnet 84 a disappears, but an attractive force between them is produced which is defined as a first attracting force having an opposite direction with the first repulsive force. With the first attracting force, the cover 70 slides back to the first room 620 c from the second room 620 d to return to the state of covering the power outlets 610, and the first electromagnet 84 a is back to the initial state. Therefore, the power supply socket 1 is back to the initial state shown in FIG. 5 a, and at this time the location of the housing 60 is defined as the second predetermined location of the housing 60. At last, the cover 70 slides back and forth relative to the housing 60 between the first predetermined location and the second predetermined location under the first repulsive force and the first attracting force, so as to switch the states of the power supply socket 1 between the non-working state and the working state.
As Shown in FIG. 3 and FIG. 4, in order to drive the cover 70 to slide more quickly relative to the housing 60, each sliding mechanism 80 further includes a second magnet 82 b and a second electromagnet 84 b. The second electromagnet 84 b includes a second iron core 842 b and a second coil 844 b wound around the second iron core 842 b. FIGS. 6 a-6 c show different states of the cover 70 changed under a force of the first and second magnets 82 a, 82 b, and the first and second electromagnets 84 a, 84 b. In the embodiment, the second magnet 82 b is a permanent magnet, and the second iron core 842 b is an iron. The second magnet 82 b and the second electromagnet 84 b are disposed respectively in the other notch 710 of the cover 70 and the other receiving groove 630 of the housing 60, and are opposite to each other (shown in FIG. 3). In other embodiments, the notch 710 can be omitted, and the first and the second magnets 82 a, 82 b are fixed on two opposite sidewalls of the cover 70. Further, in another embodiment, the cover 70 can be a rectangular permanent magnet having a N pole and a S pole, where the N pole and the S pole are used as the first and second magnets 82 a and 82 b of the sliding mechanism 80, respectively.
FIG. 6 a shows an initial state of the power supply socket 1, the difference between the FIG. 5 a and FIG. 6 a is that the sliding mechanism 80 of FIG. 6 a further includes the second magnet 82 b and the second electromagnet 84 b, the second electromagnet 84 b is in an initial state having no magnetism, and the end of the second magnet 82 b adjacent to the second electromagnet 84 b is a N pole and the other end is a S pole.
When the switch 640 is pressed to power on the power supply socket 1 to energize the first coil 844 a to produce the current I. Similar to FIGS. 5 a-5 b, the first magnet 82 a and the first electromagnet 84 a repulse each other and produce the first repulsive force. Since an attractive force exists between an iron and a permanent magnet, the second magnet 82 b and the second iron core 842 b attract each other and produce a second attracting force with the same direction as the first repulsive force, to drive the cover 70 to slide from the first room 620 c to the second room 620 d more quickly driven by the first repulsive force and the second attracting force. Therefore, the cover 70 slides from the first room 620 c to the second room 620 d to expose the power outlets 610, and at this time, the location of the housing 60 is defined as the first predetermined location of the housing 60. Thus, the state of the cover 70 is switched from the state shown in FIG. 6 a to the state shown in FIG. 6 b.
Then, when the switch 640 is pressed again to power off the power supply socket 1 to de-energize the first coil 844 a and to energize the second coil 844 b to produce the current I, and the second iron core 842 b becomes a magnet. The reserve power resource 40 supplies power to the second electromagnet 84 b. Thus, the first iron core 842 a is de-magnetized and back to an iron. The second iron core 842 b is magnetized to become a magnet and has a contrary magnetic polarity with the second magnet 82 b, and one end of the magnetized second iron core 842 b adjacent to the second magnet 82 b is magnetized to be determined as a N pole according to the Ampere's Right Hand Rule.
Thus, the first attracting force is produced by the first magnet 82 a and the first electromagnet 84 a. At this time, the second magnet 82 b and the magnetized second iron core 842 b repulse each other and produce a second repulsive force, and the second repulsive force has the same direction with the first attracting force. Under driven of the first attracting force and the second repulsive force, the cover 70 slides over to the first room 620 c from the second room 620 d and is latched in the first room 620 c, and at this time the location of the housing 60 is defined as the second predetermined location of the housing 60. At last, the state of the cover 70 is switched from the state shown in FIG. 6 b to the state shown in FIG. 6 c.
When the cover 70 slides to the state shown in FIG. 6 c, the reserve power source 40 stops supplying power to the second electromagnet 84 b, to de-energize the second coil 844 b. Thus, each of the cover 70, the first and the second electromagnets 84 a, 84 b goes back to their initial state, and the power supply socket 1 returns to its initial state shown in FIG. 6 a.
In another embodiment, each sliding mechanism 80 further includes an elastic part 86 (shown in FIG. 3). The elastic part 86 is disposed between the housing 60 and each cover 70. The elastic part 86 is deformed when the cover 70 moves away from the first iron core 842 a, and recovers its deformation when the cover 70 moves towards the first iron core 842 a to drive each cover 70 to slide more quickly relative to the housing 60.
Further referring to FIG. 3, a first protrusion 740 protrudes from the surface of each cover 70 adjacent to the sliding groove 730. Correspondingly, a protrusion (not shown) protrudes from the bottom of each receiving room 620, one end of the elastic part 86 is disposed on the corresponding first protrusion 740, and the other end is disposed on the corresponding protrusion of the housing 60. In addition, the housing 60 further includes at least one sliding part (not shown). The cover 70 can slide back and forth in the receiving room 620 along the at least one sliding part to cover or expose the power outlets 610. In another embodiment, the receiving room 620 of the housing 60 can be omitted, the power outlets 610 are disposed on the surface of the housing 60, and the cover 70 slides on the surface of the housing 60 to work at different states.
FIG. 3 show that the power supply socket 1 further includes at least one fixing member 90. The at least one fixing member 90 is located in the corresponding second room 620 d of the housing 60, and has the same dimensions as that of the corresponding second room 620 d. Thus, the bottom wall of each fixing member 90 resists the corresponding connecting surface 620 e, so that the cover 70 can slide on the fixing member 90 smoothly. Each sliding mechanism 80 further includes the elastic part 86 located between each cover 70 and a corresponding fixing member 90.
Each elastic part 86 is a torsional spring. Each fixing member 90 includes a square main body 910 and two sliding parts 920 extending outward from the two opposite sidewalls of the main body 910. The two sliding parts 920 are received in the sliding groove 730 of the cover 70 and also can slide in the sliding groove 730. A second protrusion 9101 protrudes from a surface of the main body 910 adjacent to the cover 70, and two ends of each elastic part 86 are respectively disposed on the first protrusion 740 and the second protrusion 9101. At least two through holes 650 are defined at the bottom of each second room 620 d of the housing 60 and at least two locating parts 9103 protrude from the surface of each main body 910 away from the cover 70. The at least two locating parts 9103 are facing the at least two through holes 650. The at least two locating parts 9103 can respectively pass through the at least two through holes 650 by a screw to fix the fixing member 90 in the housing 60. In other embodiment, each fixing member 90 may adhere in the housing 60.
