Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with electrically retractable plug pins. Background Art

[0002] Power adapters are widely used to charge a variety of mobile electronic devices, but there are problems with their use. Users often keep the adapter plugged in for a long time. On the one hand, the device is still connected after charging is completed, and the adapter is in standby mode. Although the power consumption of a single standby device is not obvious, when used on a large scale, such as in large offices or homes with multiple adapters on standby for a long time, the total energy consumption in a year is astonishing. On the other hand, the adapter pins are fixed in the socket and cannot be flexibly unplugged. In the event of a sudden power failure, such as a short circuit or overvoltage, the network cannot be automatically disconnected, and the internal circuit will be damaged by abnormal impact. In special scenarios, such as when the user is away for a long time, it is not convenient to disconnect, which not only increases safety hazards such as electrical fires, but also causes energy waste. This fixed connection method brings inconvenience and risks in many cases.

[0003] Most power adapters currently on the market lack effective design improvements to address the aforementioned issues. Traditional power adapters primarily focus on charging functionality, such as providing stable output voltage and current to meet the charging needs of various electronic devices. While some energy-saving standards have been proposed to address standby power consumption, these primarily focus on the power adapter's energy efficiency and do not fundamentally address the energy waste caused by prolonged standby. Existing technology primarily relies on a simple physical plug-and-unplug mechanism to connect the power adapter to the outlet. Once inserted, the plug can only be removed manually by the user, lacking an intelligent automatic disconnect mechanism.

[0004] This lack of automatic power-off and flexible connection control functions is not only contrary to the current increasingly emphasized concept of energy conservation, but also fails to meet modern people's higher requirements for electricity safety and convenience. With the increasing popularity of smart devices and the improvement of people's environmental awareness and safety awareness, the existing power adapter technology can no longer adapt to the development trend of market demand. There is an urgent need for a new power adapter technology that can solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 In an embodiment of the present invention, a power adapter with electrically retractable pins is provided, comprising a housing 10, a screw mechanism 20 disposed within the housing 10, an active monitoring module 30 disposed within the housing 10 for driving the screw mechanism 20, conductive pins 40 movably connected to the housing 10 and driven by the screw mechanism 20 to be retracted outside the housing 10, and a main circuit module 50 disposed within the housing 10 and electrically connected to the conductive pins 40.

[0026] Among them, the conductive pin 40 is used to connect the socket, the main circuit module 50 and the active monitoring module 30 are both powered by the conductive pin 40, the active monitoring module 30 and the main circuit module 50 exchange data, and the screw mechanism 20 is provided with a guide part 21 fixed inside the shell 10, a movable seat 22 slidingly connected to the guide part 21, and a screw electric part 23 installed inside the shell 10 and driving the movable seat 22 to move along the guide part 21. The conductive pin 40 is installed on the movable seat 22, and the screw electric part 23 is electrically connected to the active monitoring module 30.

[0027] In the above technical solution, when the power adapter is connected to the socket, the conductive pin 40 extends from the housing 10 and is connected to the socket, and starts to supply power to the active monitoring module 30 and the main circuit module 50. The active monitoring module 30 will continuously monitor the power supply status, including charging status, current, voltage and other parameters; during the charging process, the active monitoring module 30 transmits information such as the charging status to the main circuit module 50, and the main circuit module 50 outputs appropriate voltage and current according to the charging requirements of the device; when charging is completed, the active monitoring module 30 detects that the device is fully charged or in a long-term standby state according to the set threshold value, for example, if the current is lower than a certain value for a long time, it will send a signal to the screw motor 23; the screw motor 23 starts to work after receiving the signal from the active monitoring module 30, and the screw motor 23 drives the movable seat 22 along the guide portion 21 Movement, since the conductive pin 40 is installed on the movable seat 22, the movement of the movable seat 22 will cause the conductive pin 40 to retract into the shell 10. When the conductive pin 40 is completely retracted into the shell 10, the circuit connection between the power adapter and the socket is cut off, thereby avoiding power consumption in the standby state. In the event of a sudden power failure, such as a short circuit or excessive voltage, the active monitoring module 30 detects abnormal voltage or current fluctuations, and it will also send a signal to the lead screw electric part 23, causing the lead screw electric part 23 to drive the conductive pin 40 to retract, thereby protecting the internal circuit of the power adapter from damage due to abnormal impact; when the power adapter needs to be used to charge the device again, the power adapter can control the lead screw electric part 23 to work in reverse through the active monitoring module 30, extend the conductive pin 40 from the shell 10, and reconnect it to the socket to restore the charging function.

[0028] Through this technical solution, after charging is completed or when the device is not connected, the connection with the socket is disconnected by automatically retracting the pins, avoiding the energy waste caused by the long standby period of the traditional power adapter. In large-scale usage scenarios, such as large offices or homes with multiple power adapters, this automatic power-off function can significantly reduce the total standby power consumption, which is in line with the concept of energy conservation. In the event of a sudden power failure, such as a short circuit or overvoltage, the pins can be automatically retracted to disconnect, effectively protecting the internal circuit of the power adapter from damage due to abnormal impact, reducing the risk of equipment damage caused by power failure; for special scenarios such as users being away for a long time, automatic disconnection reduces safety hazards such as electrical fires and improves the safety of electricity use. The design of the electrically retractable pins changes the situation in which the traditional power adapter pins are fixedly plugged into the socket and cannot be flexibly unplugged. There is no need for users to manually plug and unplug the pins, providing a more intelligent and convenient user experience.

[0029] See also Figure 3 This embodiment further proposes that the guide portion 21 is a plurality of guide rods slidably connected to the corners of the movable seat 22, and linear bearings 24 are provided between the movable seat 22 and the guide rods. When the guide portion 21 adopts a plurality of guide rods slidably connected to the corners of the movable seat 22, this structure provides precise guidance for the movement of the movable seat 22. The plurality of guide rods are distributed at the corners of the movable seat 22, which can ensure that the movable seat 22 remains stable during movement without tilting or offsetting. The linear bearings 24 provided between the movable seat 22 and the guide rods further optimize this guide structure. The function of the linear bearings 24 is to reduce the friction between the movable seat 22 and the guide rods. The linear bearings 24 convert the sliding friction between the movable seat 22 and the guide rods into rolling friction through rolling elements such as internal balls or rollers.

[0030] See also Figure 3 This embodiment further proposes that a screw slider 221 is provided on the movable seat 22, and the screw motor portion 23 includes a screw body 231 connected to the interior of the housing 10 by a bearing and a motor 232 installed in the housing 10 and dynamically connected to the screw body 231. The screw body 231 drives the movable seat 22 through the screw slider 221, so that the rotation of the screw body 231 can be converted into linear motion of the movable seat 22. The screw body 231 is connected to the interior of the housing 10 by a bearing. The function of the bearing is to support the screw body 231 so that the screw body 231 can rotate stably within the housing 10. This connection method reduces the friction resistance of the screw body 231 during rotation, while ensuring that the rotation axis of the screw body 231 is fixed, thereby improving the stability of the entire mechanism.

[0031] See also Figure 2-3This embodiment further provides that the housing 10 includes a square sleeve 11, an upper cover 12 covering the upper end of the square sleeve 11, and a lower cover 13 covering the lower end of the square sleeve 11. The conductive pins 40 and the main circuit module 50 are both located in the lower cover 13. A partition 14 is also provided within the square sleeve 11. The guide portion 21 and the screw body 231 are both connected between the partition 14 and the lower cover 13. The motor 232 and the active monitoring module 30 are installed between the partition 14 and the upper cover 12. Placing the conductive pins 40 in the lower cover 13 facilitates their connection to the socket, while locating the main circuit module 50 close to the conductive pins 40 helps reduce losses during power transmission and also facilitates electrical connection with the conductive pins 40. The partition 14 is provided within the square sleeve 11, and the guide portion 21 and the screw body 231 are both connected between the partition 14 and the lower cover 13. This layout positions the guide portion 21 and the screw body 231 in the lower area of ​​the power adapter, near the conductive pins 40 and the main circuit module 50, facilitating their mechanical connection and coordinated operation. The motor 232 and active monitoring module 30 are mounted between the partition 14 and the upper cover 12. Placing the motor 232 and active monitoring module 30 in the upper area of ​​the power adapter avoids excessive spatial interference with the conductive pins 40 and the main circuit module 50, while also protecting these two relatively intelligent modules and facilitating data exchange and electrical connections with other components.

[0032] See also Figure 2-3 The present embodiment further provides a reinforcing seat 15 provided on the lower cover 13, and a through hole 16 is provided on the reinforcing seat 15 for docking with the conductive pin 40. The reinforcing seat 15 provided on the lower cover 13 is mainly used to enhance the structural strength of the lower cover 13 in the vicinity of the conductive pin 40. Since the conductive pin 40 may be subjected to various forces such as insertion and removal force and electromagnetic force during use, and needs to remain stable when connected to the socket, the reinforcing seat 15 can improve the mechanical properties of the lower cover 13 in this area, thereby preventing the lower cover 13 from deformation and damage during long-term use. The through hole 16 provided on the reinforcing seat 15 and docking with the conductive pin 40 provides a passage for the conductive pin 40 to pass through the lower cover 13. The size and shape of the through hole 16 match the conductive pin 40, which can not only ensure that the conductive pin 40 can smoothly pass through and connect to the socket, but also play a certain role in limiting and positioning the conductive pin 40, ensuring the position accuracy of the conductive pin 40 during extension and retraction.

[0033] See also Figure 1-3This embodiment further proposes that the active monitoring module 30 has a control circuit 31, a battery pack 32 and a display screen 33. The active monitoring module 30 stores electrical energy through the battery pack 32. The battery pack 32 and the control circuit 31 are both installed on the partition 14, and the display screen 33 is installed on the upper cover 12. The display screen 33, the motor 232, the battery pack 32 and the main circuit module 50 are electrically connected to the control circuit 31 respectively.

[0034] The active monitoring module 30 includes a control circuit 31, a battery pack 32 and a display screen 33. The control circuit 31 is the core part of the active monitoring module 30, which is responsible for processing various information and controlling the operation of other related components; the battery pack 32 is used for energy storage to provide the necessary power support for the active monitoring module 30, especially in some special circumstances, such as when the power adapter has just been plugged into the socket but has not yet started to obtain power from the socket, or when power is needed for certain emergency operations; the display screen 33 is installed on the upper cover 12 to facilitate users to view relevant information about the power adapter.

[0035] The battery pack 32 and the control circuit 31 are both mounted on the partition 14. This layout makes their positions inside the power adapter relatively stable and facilitates wiring and connection; the display screen 33, motor 232, battery pack 32 and main circuit module 50 are respectively electrically connected to the control circuit 31. This connection relationship enables the control circuit 31 to receive information from different components and send control instructions to them, thereby realizing the coordinated operation of various functions of the power adapter.

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 rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
