Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter capable of autonomous power on and off. Background Art

[0002] A power adapter is a device used to convert external power into the voltage and current required by electronic devices. They are typically used to convert alternating current (AC) to direct current (DC) for use in portable electronic devices.

[0003] However, traditional power adapters have some shortcomings, especially in terms of energy conservation and emission reduction and equipment safety management. Due to the intelligent power-off mechanism, many electronic devices will be in standby mode even when not in use, and continue to consume electricity. This standby power consumption will waste precious energy, especially in large office spaces, where there are often a large number of devices, which will greatly increase the user's electricity bill. In addition, safety issues are also an important consideration. For example, after the power adapter is plugged into the socket, the user can only manually unplug the power adapter, causing users to often forget to turn off and unplug the power adapter when leaving, which in turn causes the power to fail automatically in the event of a sudden power failure, greatly increasing the risk of the device being affected by the power failure, thereby causing damage to the equipment and the risk of fire.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0028] See also Figure 1-4 , a power adapter with independent power on and off, including a shell 1, which is composed of an upper shell and a lower shell. The shell 1 has an inner cavity, a circuit board 2 is provided inside the shell 1, and a connecting wire 3 electrically connected to the circuit board 2 is provided at one side end of the shell 1. The connecting wire 3 is electrically connected to the device, and a conductive pin 4 is provided on the bottom side of the shell 1. The conductive pin 4 extends into the interior of the shell 1, and a connecting pin 5 opposite to the conductive pin 4 is provided inside the shell 1. The connecting pin 5 is electrically connected to the circuit board 2, and a movable plug block 6 is provided between the conductive pin 4 and the connecting pin 5. The conductive pin 4 and the connecting pin 5 are connected through the plug block 6, so that the conductive pin 4 is electrically connected to the circuit board 2. A driving mechanism 7 connected to the plug block 6 is provided inside the shell 1, and a detection control module 8 for controlling the driving mechanism 7 is also provided inside the shell 1. The detection control module 8 is electrically connected to the circuit board 2, and the conductive pin 4, the connecting pin 5 and the plug block 6 are all made of conductive materials;

[0029] Preferably, the driving mechanism 7 includes a fixing seat 71 arranged inside the housing 1, a motor 72 is installed on the side of the fixing seat 71 away from the plug-in block 6, a screw rod 73 is provided on one side of the motor 72 and extends through the fixing seat 71 toward the plug-in block 6, a first movable plate 74 is screwed on the screw rod 73, the first movable plate 74 is connected to the side facing the plug-in block 6 with a sleeve 75, one side of the sleeve 75 is connected to a second movable plate 76, the second movable plate 76 is connected to the plug-in block 6, a guide rod 77 is connected to one side of the fixing seat 71, a first through hole 78 is opened on the first movable plate 74, the first movable plate 74 is guided and slidably connected to the guide rod 77 through the first through hole 78, wherein the inner diameter of the sleeve 75 is larger than the radius of the screw rod 73, the detection control module 8 includes a control board 81, a main control chip 82 and a current detection module 83 and a power supply module 84 on the control board 81;

[0030] Among them, the current detection module 83 is electrically connected to the circuit board 2, and can be a Hall sensor, and the Hall sensor is set with a minimum current threshold. When the Hall sensor detects the current consumption signal of the device, the main control chip 82 can receive and process the electrical signal of the Hall sensor, and can judge whether the device is in use or not based on the size of the current consumption, and control the driving mechanism 7 according to the state. At the same time, the power supply module 84 is used to provide power to the driving mechanism 7 to drive the plug block 6 to be inserted between the conductive pin 4 and the power pin 5 or to be removed from between the conductive pin 4 and the power pin 5, thereby controlling the circuit board 2 to be powered on or off.

[0031] Specifically, when the device is in standby mode, the current signal of the device is detected by the current detection module 83 and reaches the set minimum current threshold. Then, the main control chip 82 receives the electrical signal and controls the motor 72 to start. The motor 72 drives the screw rod 73 to rotate. The rotation of the screw rod 73 causes the screwed first movable plate 74 to move away from the conductive pin 4 and the power pin 5. The first through hole 78 can be used to guide the first movable plate 74 to slide and be screwed on the guide rod 77, so that the first movable plate 74 is not affected by the rotation force of the screw rod 73. Then, the first movable plate 74 passes through the sleeve. The sleeve 75 drives the second movable plate 76. Since the inner diameter of the sleeve 75 is larger than the radius of the screw rod 73, the sleeve 75 is not affected by the screw rod 73 when it reciprocates. The second movable plate 76 drives the plug block 6, so that the plug block 6 moves out from between the conductive pin 4 and the power pin 5, so that the electrical connection between the circuit board 2 and the socket is disconnected, thereby realizing the function of automatically powering off the device in the standby state, reducing the energy consumption of the device when not in use, achieving the effect of energy saving and emission reduction, and at the same time improving the safety of use, avoiding damage to the device in the event of a sudden power failure;

[0032] When the device enters the use state, the current detection module 83 detects the electrical signal during operation, and the signal strength exceeds the set threshold. The main control chip 82 determines that the device is in use when receiving the electrical signal, and then controls the motor 72 to drive the screw rod 73 to rotate in the opposite direction, so that the first movable plate 74, the sleeve 75 and the second movable plate 76 push the plug block 6 to move between the conductive pin 4 and the power pin 5, and then connect the conductive pin 4 and the power pin 5, so that the electrical connection between the circuit board 2 and the socket is restored, thereby restoring the function of charging the device.

[0034] Specifically, when the plug-in block 6 moves toward the conductive pin 4 and the connecting pin 5, it will be inserted into the two "U"-shaped conductive parts of the jaws 9, and during the insertion process, it will push the arched spring pieces 91 on both sides, causing the arched spring pieces 91 to deform. At the same time, the elastic recovery property can be used to make the top of the arch always support the plug-in block 6, thereby making the connection stable and improving the power supply quality.

[0035] Preferably, one end of the arched spring piece 91 close to the plug-in block 6 is fixedly connected to the jaw conductive portion 9, and the other end is movably arranged.

[0036] Specifically, when the plug-in block 6 is inserted into the conductive portion 9 of the jaws, the arched spring piece 91 is fixed near one end of the plug-in block 6 to prevent the arched spring piece 91 from moving, while the movable setting at the other end provides space for the arched spring piece 91 to deform when the plug-in block 6 pushes the arched spring piece 91.

[0037] Preferably, there are two conductive pins 4 , two connecting pins 5 and two plug-in blocks 6 . The two plug-in blocks 6 are connected to a T-shaped frame 61 on the side facing the driving mechanism 7 . The T-shaped frame 61 is connected to the second movable plate 76 .

[0038] Specifically, the T-shaped frame 61 can be used to simultaneously drive the two plug-in blocks 6 to move, and the T-shaped frame 61 is made of insulating material to ensure that the two plug-in blocks 6 are kept insulated.

[0039] Preferably, a second through hole 79 is defined on the second movable plate 76 , and the second movable plate 76 is slidably connected to the guide rod 77 via the second through hole 79 .

[0040] Specifically, when the second movable plate 76 is pushed by the first movable plate 74 and the sleeve 75, the second movable plate 76 is slidably connected to the guide rod 77 through the second through hole 79, which can provide a guiding effect for the second movable plate 76 and improve the stability of the second movable plate 76 when moving, so as to ensure that the plug-in block 6 can be accurately plugged into the conductive part 9 of the jaws.

[0041] Preferably, a bearing sleeve 10 is disposed in each of the first through hole 78 and the second through hole 79 , and the guide rod 77 is inserted into the bearing sleeve 10 .

[0042] Specifically, when the first movable plate 74 and the second movable plate 76 slide on the guide rod 77, the bearing sleeve 10 provided in the first through hole 78 and the second through hole 79 can increase the smoothness between the first through hole 78 and the second through hole 79 and the guide rod 77, reduce friction resistance, and make the first movable plate 74 and the second movable plate 76 move more smoothly.

[0043] Preferably, a partition 11 is provided inside the shell 1, the circuit board 2 is installed between the partition 11 and the top surface of the inner cavity of the shell 1, and the driving mechanism 7, the detection control module 8, the conductive pin 4, the power pin 5 and the plug block 6 are arranged between the partition 11 and the bottom surface of the inner cavity of the shell 1.

[0044] Specifically, the partition 11 provided inside the housing 1 is used to separate the circuit board 2 and the drive mechanism 7, the detection control module 8, the conductive pins 4, the power pins 5 and the plug block 6, which can facilitate the layout of the mechanism.

[0045] Preferably, a reinforcement block 12 is provided on the bottom side of the housing 1 at a position corresponding to the conductive pin 4 , and the reinforcement block 12 defines a socket corresponding to the conductive pin 4 .

[0046] Specifically, when the plug block 6 is inserted into or removed from the conductive portion 9 of the jaws, the conductive pins will inevitably be affected by the friction force. Therefore, by adding the reinforcement block 12, the strength of the conductive pins 4 is improved to prevent the conductive pins 4 from tilting. At the same time, the conductive pins 4 and the reinforcement block 12 are fixedly connected by gluing, welding, etc., so that the strength of the conductive pins 4 is sufficient when pulled out.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
