[0013] The technical effects and advantages of the present invention:

[0014] 1. The present invention inserts the plug into the socket, and the conductive metal on the plug will push the pressure plate to rotate in the rotating frame, and then the bottom of the pressure plate will rotate and press down the lifting seat, so that the lifting seat moves downward. When the lifting seat moves downward, it will drive the second conductive spring, the first contact block and the metal spring to descend, and the metal spring will contact one of the second contact blocks on the live conductive strip, so that the second conductive spring at the current position is connected to the power supply on the live conductive strip, thereby achieving the effect of opening the clutch mechanism, and then the conductive metal on the plug will be inserted into the first conductive spring and the second conductive spring, so that after the plug is inserted into the socket, the switch component can be synchronously opened and the power can be connected. When the plug is pulled out, the trigger mechanism will be released, and then under the action of the first spring, the first spring will push the lifting seat to rise, so that the metal spring is separated from the second contact block on the live conductive strip, and the switch component will be closed, so that when the power is used, the switch is automatically turned on when the plug is inserted into the socket, and the switch is automatically turned off when the plug is pulled out.

[0015] 2. The present invention can seal the jack through the blocking plate when the power supply is not in use to prevent foreign matter from entering the housing. When the power supply is in use, when the plug is inserted into the movable jack, the conductive metal on the plug will press down the pressure block, and the pressure block will press down the card block, so that the card block will retract into the telescopic groove and move out of the card groove. Then, when the conductive metal on the plug continues to press down, the blocking plate can be driven to open, so that the conductive metal is inserted into the jack to connect the power supply.

[0016] 3. The present invention achieves the effect of limiting the opening of a single blocking plate through the action of the first gear and the second gear. The blocking plate can only be opened by pushing the two blocking plates downward at the same time to move the two card blocks out of the card slots, which can effectively prevent children from inserting foreign objects into the shell.

Detailed implementation manners

[0029] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and an intelligent power switch related to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0030] Such as Figures 1-10As shown, in one embodiment, an intelligent power switch is proposed, which includes a bottom case 1. An outer case 101 and a switch assembly 2 are installed on the upper end of the bottom case 1. A plurality of jacks 102 are provided on the upper end face of the outer case 101. A plugging component 3 and a heat dissipation component 4 are arranged inside the outer case 101. A neutral conductor bar 103 and a live conductor bar 104 are installed inside the bottom case 1. A plurality of first conductive spring pieces 105 are installed on the surface of the neutral conductor bar 103. The switch assembly 2 includes a clutch mechanism 21 and a trigger mechanism 22. The clutch mechanism 21 includes a guide rod 211, a lifting seat 212, a second conductive spring piece 214, a first contact block 215, a second contact block 217 and a metal spring piece 216. A plurality of guide rods 211 are all installed on the upper end of the bottom case 1. The lifting seat 212 is slidably connected to the circumferential surface of the guide rod 211. A first spring 213 is installed between the lifting seat 212 and the bottom case 1. The second conductive spring piece 214 is installed on the upper end of the lifting seat 212. The first contact block 215 is installed at the lower end of the second conductive spring piece 214. The metal spring piece 216 is installed at the lower end of the first contact block 215. The second contact block 217 is installed on the surface of the live conductor bar 104.

[0031] In the actual application of the embodiment of the present invention, by inserting the power plug into the jack 102, at this time, the conductive metal on the plug will contact the trigger mechanism 22, driving the trigger mechanism 22 to operate, so that the lifting seat 212 moves downward. After the lifting seat 212 moves downward, it will drive the second conductive spring piece 214, the first contact block 215 and the metal spring piece 216 to move downward. At this time, the metal spring piece 216 will contact one of the second contact blocks 217 on the live conductor bar 104, so that the second conductive spring piece 214 at the current position is connected to the power supply on the live conductor bar 104, thus achieving the effect of opening the clutch mechanism 21. Subsequently, the conductive metal on the plug will be inserted into the first conductive spring piece 105 and the second conductive spring piece 214, so that after the plug is inserted into the jack 102, the switch assembly 2 will be opened and connected to the power supply synchronously. When the plug is pulled out, at this time, the trigger mechanism 22 will be released. Subsequently, under the action of the first spring 213, the first spring 213 will push the lifting seat 212 to rise, so that the metal spring piece 216 is separated from the second contact block 217 on the live conductor bar 104, and the switch assembly 2 will be closed, realizing the effect that when using the power supply, the switch automatically opens when the plug is inserted into the jack 102 and the switch automatically closes when the plug is pulled out.

[0032] As Figure 7 and 10 As shown, as a preferred embodiment of the present invention, the trigger mechanism 22 includes a rotating frame 221, a pressing plate 222 and a first pulling spring 224. A pair of rotating frames 221 are installed on the upper end of the bottom case 1. The pressing plate 222 is rotatably connected to the inside of the rotating frame 221 through a rotating shaft 223. The first pulling spring 224 is installed between the rotating frame 221 and the pressing plate 222.

[0033] In the actual application of the embodiment of the present invention, when the plug is inserted into the jack 102, the conductive metal on the plug will push the pressing plate 222 to rotate within the rotating frame 221. Subsequently, the bottom of the pressing plate 222 will rotate downward to press the lifting seat 212, thereby achieving the effect of controlling the lifting seat 212 to descend and turn on the switch. When the plug is pulled out, under the action of the first tension spring 224, the first tension spring 224 will pull the pressing plate 222 to reset, causing it to disengage from the lifting seat 212. Subsequently, the lifting seat 212 will reset under the action of the first spring 213, turning off the power switch.

[0034] As Figure 7 , 8 As shown in FIGS. 9, as another preferred embodiment of the present invention, the plugging assembly 3 includes a rotating plate 301, a rotating rod 303, a blocking plate 304, and a locking block 302. Multiple groups of rotating plates 301 and multiple groups of locking blocks 302 are both installed within the housing 101. A pair of rotating rods 303 are rotatably connected within the rotating plate 301. The blocking plate 304 is installed on the circumferential surface of the rotating rod 303. Telescopic grooves 305 are respectively formed within the blocking plate 304. A clamping block 306 is slidably connected within the telescopic groove 305. A second spring 307 is installed between the clamping block 306 and the blocking plate 304. A card slot 308 is formed on the surface of the locking block 302. The clamping block 306 cooperates with the card slot 308. A pressing block 309 is slidably connected within each clamping block 306, and the pressing block 309 is slidably connected with the clamping block 306.

[0035] In the actual application of the embodiment of the present invention, under the action of the blocking plate 304, when the power is not in use, the jack 102 can be plugged to prevent foreign objects from entering the housing 101. When using the power, when the plug is inserted into the moving jack 102, the conductive metal on the plug will press down the pressing block 309. The pressing block 309 will press down the clamping block 306, causing the clamping block 306 to retract into the telescopic groove 305 and move out of the card slot 308. Subsequently, when the conductive metal on the plug continues to press down, it can drive the blocking plate 304 to open, enabling the conductive metal to be inserted into the jack 102 to connect the power supply.

[0036] As Figure 8 and 9 As shown in FIGS., as another preferred embodiment of the present invention, a clockwork spring 3010 is installed on the circumferential surface of the rotating rod 303. One end of the clockwork spring 3010 away from the rotating rod 303 is fixedly connected to the rotating plate 301. A second tension spring 3011 is installed within the blocking plate 304, and the second tension spring 3011 is fixedly connected to the pressing block 309.

[0037] In the actual application of the embodiment of the present invention, under the action of the clockwork spring 3010, when the plug is pulled out from the jack 102, the blocking plate 304 can be driven to rotate and reset. At the same time, under the action of the second tension spring 3011, the pressing block 309 immediately resets upward after being separated from the conductive metal on the plug, reducing the reset resistance when the clamping block 306 contacts the locking block 302. Since the torque of the clockwork spring 3010 is much greater than the tension of the second spring 307, when the clockwork spring 3010 drives the blocking block to reset, the clamping block 306 will contact the locking block 302 and then be squeezed and retracted. After the blocking plate 304 is completely reset, under the action of the second spring 307, the clamping block 306 is pushed into the card slot 308 to lock the blocking plate 304, ensuring that the blocking plate 304 can be reset to complete the blocking of the jack 102.

[0038] As Figure 8 and 9 shown, as another preferred embodiment of the present invention, a pair of connecting rods 3012 are rotatably connected between the rotating plates 301. The circumferential surfaces of the connecting rods 3012 are respectively provided with first gears 3013 that mesh with each other. The circumferential surfaces of the rotating rods 303 are respectively provided with second gears 3014, and the first gears 3013 are all meshed with the second gears 3014.

[0039] In the actual application of the embodiment of the present invention, under the action of the first gear 3013 and the second gear 3014, the effect of restricting the single opening of the blocking plate 304 is achieved. Only by simultaneously pushing down the two blocking plates 304 to move the two clamping blocks 306 out of the card slot 308 can the blocking plate 304 be opened, effectively preventing children from inserting foreign objects into the housing 101.

[0040] As Figure 1 , 2 and shown in FIG. 4, as another preferred embodiment of the present invention, the heat dissipation component 4 includes an isolation frame 401, a motor 402, a driving rod 403, and fan blades 404. The isolation frame 401 is installed in the housing 101, the motor 402 is installed in the isolation frame 401, the driving rod 403 is installed at the output end of the motor 402 and is rotatably connected to the isolation frame 401, and a plurality of fan blades 404 are all installed on the circumferential surface of the driving rod 403. Air intake holes 405 are opened on the left and right end faces of the housing 101, a communication hole 406 is opened on the surface of the isolation frame 401, and an exhaust hole 407 is opened at the rear end of the housing 101.

[0041] In the actual application of the embodiment of the present invention, when using the power supply, if multiple plugs are connected simultaneously during the power supply usage, it may cause the power supply to heat up. At this time, the temperature sensor in the housing 101 can sense the temperature of the power supply during operation, and then transmit a signal to the controller to start the motor 402 to operate. The motor 402 drives the fan blade 404 to rotate through the driving rod 403. Air enters the housing 101 through the air inlet hole 405, then enters the switch area through the communication hole 406, and finally is discharged through the exhaust hole 407, achieving the effect of dissipating heat during the operation of the power supply switch. Since the air inlet hole 405 and the communication hole 406 are arranged in a staggered manner, it can effectively prevent water stains or foreign objects from directly entering the power supply switch area inside the housing 101.

[0042] As Figure 3 and 4 shown, as another preferred embodiment of the present invention, a cam 408 is installed on the circumferential surface of the driving rod 403. A displacement plate 409 is slidably connected inside the housing 101. The cam 408 is slidably connected to the displacement plate 409. A displacement hole 4010 is formed on the surface of the displacement plate 409. A third tension spring 4011 is installed between the displacement plate 409 and the housing 101.

[0043] In the actual application of the embodiment of the present invention, when the driving rod 403 rotates, the driving rod 403 will drive the cam 408 to rotate. The rapidly rotating cam 408 will drive the displacement plate 409 to always be in a lowered position, so that when the heat dissipation component 4 is turned on, the displacement hole 4010 formed on the surface of the displacement plate 409 corresponds to the position of the exhaust hole 407, and the exhaust hole 407 is only in an open state during heat dissipation. During daily use, the exhaust hole 407 will be blocked and closed by the displacement plate 409.

[0044] As Figure 3 and 4 shown, as another preferred embodiment of the present invention, a pair of guide shafts 4012 are installed inside the housing 101. A lifting plate 4013 is slidably connected to the circumferential surface of the guide shafts 4012. A fourth tension spring 4014 is installed between the lifting plate 4013 and the housing 101. An eccentric convex block 4015 is installed on the surface of the cam 408. The lifting plate 4013 is slidably connected to the eccentric convex block 4015.

[0045] In practical applications of the embodiments of the present invention, when the heat dissipation component 4 is turned on, the eccentric bump 4015 will drive the lifting plate 4013 to be in a continuous descending state. When the heat dissipation component 4 is turned off, the driving rod 403 will be in an inertial rotation state. At this time, under the action of the fourth tension spring 4014, the fourth tension spring 4014 pulls the lifting plate 4013 upward, and the lifting plate 4013 will push the eccentric bump 4015 upward, so that after the driving rod 403 stops rotating, the convex part of the cam 408 faces upward, avoiding the convex part of the cam 408 contacting the misalignment plate 409 when the driving rod 403 stops rotating, and preventing the misalignment plate 409 from resetting upward.

[0046] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense, which can be a mechanical connection or an electrical connection, or the internal communication of two components, and can be directly connected. The terms "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;

[0047] Second: In the drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0048] Finally: The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
