Description

Technical Field

[0001] This utility model relates to the field of socket technology, and more specifically, to a safety sensor adapter and a safety sensor track socket. Background Technology

[0002] With the widespread use of electricity in homes, household electrical safety is becoming increasingly important. Although more and more families are taking various measures to improve electrical safety, reports of children being electrocuted still occur frequently. According to surveys, over 70% of child electrocution accidents happen at home, even with adult supervision. Similarly, similar safety risks exist for the elderly and pets.

[0003] Existing sockets pose a risk of electric shock due to accidental activation by children, especially track sockets, where the risk is even higher. Furthermore, simply using child or pet location sensors for sockets doesn't prevent the socket from automatically shutting off when a pet or child approaches, impacting user experience. Additionally, conventional sensing methods using infrared heat source sensors can only detect heat signals, making them susceptible to obstruction and inaccurate readings.

[0004] Therefore, designing a safe socket that can effectively prevent children from accidentally touching the switch and causing electric shock, with accurate sensing, and also prevent accidental power outages while the socket is in use, thus protecting electrical safety without affecting user experience, is a problem that urgently needs to be solved by those skilled in the art.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0040] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] See Figures 1 to 3 This utility model provides a safety sensor adapter 100, which can effectively prevent children from accidentally touching the switch and causing electric shock risk. It has accurate sensing and can also prevent the socket from accidentally cutting off the power when it is in use. It can protect electrical safety without affecting the user experience.

[0042] The safety sensor adapter 100 provided in this embodiment includes an adapter housing 110, a current detection device 130, a sensor radar 150, and a power-off control device 170. The front of the adapter housing 110 has at least one hole 111 for inserting a load-side plug, and at least one plug-in module 190 is disposed inside the adapter housing 110. The plug-in module 190 corresponds to the hole 111 and is configured to connect to the load-side plug. The current detection device 130 is disposed inside the adapter housing 110 and connected to the plug-in module 190, configured to detect the current value of the plug-in module 190. The sensor radar... The 150 is disposed inside the adapter housing 110 and close to the front of the adapter housing 110, and is configured to detect the obstruction signal on the front of the adapter housing 110; the power-off control device 170 is disposed inside the adapter housing 110 and connected to the plug-in module 190, and the power-off control device is also communicatively connected to the current detection device 130 and the sensing radar 150, and is configured to control the power-on and power-off status of the plug-in module 190; wherein, the power-off control device 170 is configured to control the plug-in module 190 to power off when the current value detected by the current detection device 130 is less than a preset value and the sensing radar 150 detects an obstruction signal.

[0043] It should be noted that the preset value here can be the standby current value of the load, and the safety sensor adapter 100 can be an adapter for a track socket. This adapter can be plugged into the safety track and can achieve safety protection for the track socket. Of course, the safety sensor adapter 100 can also be a regular wall socket product, which can be installed in a groove in the wall and can also achieve safety protection for the socket.

[0044] It is worth noting that in this embodiment, a hole 111 is provided on the front of the adapter housing 110, and a plug module 190, a current detection device 130, a sensing radar 150, and a power-off control device 170 are provided inside the adapter housing 110. The plug module 190 corresponds to the hole 111, so that it can be connected to the load-side plug inserted into the hole 111. The current detection device 130 can detect the current value of the plug module 190, thereby providing a basis for judging whether the load appliance is working normally. When the current value is greater than the preset value, it means that the load appliance is working normally, and the power-off action will not be triggered. When the current value is less than or equal to the preset value, it means that the load appliance is not working or is only in standby mode. In this case, the power-off action can be triggered in combination with the obstruction situation, which is safe and reliable. The sensing radar 150 is positioned near the front of the adapter housing 110 and can detect any obstruction signals. The power-off control device 170 can control the power-off of the socket module 190 when the current value of the socket module 190 is less than a preset value and the front of the adapter housing 110 is obstructed, thus achieving safety protection for the adapter. Therefore, this embodiment of the invention uses the sensing radar 150 to determine the approaching object, which is more accurate and reliable than heat source detection. The additionally designed current detection device 130 can detect the current value to determine if any electrical appliance is in use. When no electrical appliance is in normal use and a child, pet, or other object is near the adapter, the power-off control device 170 can cut off the power, effectively preventing the risk of electric shock caused by accidental switch activation by children. Furthermore, the power-off occurs when the electrical appliance is not in use, preventing accidental power-off while in use, thus protecting electrical safety without affecting the user experience.

[0045] It is worth noting that the current detection device 130 here can be a current sensor, model BL0942 / SSOP10L or LF1005-S, both of which are existing models. The current detection device 130 can detect the current value of the socket module 190 in real time, thereby obtaining the real-time operating status of the socket module 190. The current value is detected when the load appliance is inserted into the hole 111 and is operating; otherwise, no current value is detected.

[0046] The radar 150 mentioned here can be a 5.8G radar module (model MS58-1616S14M4), a miniaturized 5.8G radar sensor module. The module uses a high-performance radar sensor paired with a miniaturized planar antenna, achieving optimal sensor performance while maintaining a size of only 16*16mm. This sensor transmits and receives high-frequency electromagnetic waves, detecting the frequency difference between the transmitted and received signals using the Doppler principle, which can be used to determine the presence of moving objects in an area. The sensor is unaffected by ambient temperature, humidity, airflow, dust, noise, or brightness. The module incorporates multiple filtering algorithms, providing strong anti-interference capabilities, and its signal can penetrate non-metallic materials such as glass and acrylic. It can be used in various scenarios for detecting human movement or moving targets, including smart homes, and is particularly suitable for applications such as nightlights, solar streetlights, and wireless cameras. The module comes with default parameters, and users can also flexibly modify various module attributes via IIC or configure the module settings by configuring pin levels.

[0047] Of course, the "Inductive Radar 150" mentioned here can also be a 24G radar module (model MS24-1515D12M4-3V3-G-5D-NLS-1T1R). This radar module is a miniaturized, high-performance millimeter-wave 24G radar sensor module that supports FMCW mode and has a 1T1R antenna. The module uses a high-power radar sensor combined with a miniaturized planar antenna, achieving optimal sensor performance while keeping the size to 15*15mm. The module has a built-in complete transmit-receive link and ADC converter. The transmitter has a 0° / 180° BPM phase shifter function, providing a maximum RF output power of 11dBm. The receiver channel is also flexibly configurable, easily handling application scenarios with different sweep rates through flexible combinations of programmable gain and high-pass / low-pass filters. The module comes with default parameters at the factory, and users can also flexibly modify various module attributes and set module levels via UART. Its application scenarios can include smart homes (such as wall switches, refrigerators, etc.), motion target sensing (such as human presence sensors, etc.), smart lighting (such as mining lamps, disinfection lamps, vanity lights, and lighting for consumer electronics products), or security and smart monitoring (such as cameras, etc.).

[0048] Furthermore, the socket module 190, the current detection device 130, and the power-off control device 170 are all individual units. Specifically, the adapter can be a 3-hole socket, the hole position 111 can be a single 3-hole socket, the socket module 190 corresponds to the hole position 111, the current detection device 130 detects the current of the single socket module 190, and the power-off control device 170 realizes the power-on and power-off control of the socket module 190. Therefore, the power-off control device 170 can act as a switch, enabling the adapter to achieve a 3-hole, 1-position structure.

[0049] In some preferred embodiments, the power-off control device 170 includes a relay that is communicatively connected to both the sensing radar 150 and the current detection device 130. The relay is configured to disconnect when the current detection device 130 detects a current value less than or equal to a preset value and the sensing radar 150 detects an obstruction signal, thereby de-energizing the socket module 190. The relay is also configured to shield the sensing radar 150 and energize it when the current detection device 130 detects a current value greater than a preset value, thereby energizing the socket module 190. The preset current value is preferably between 1 and 10 mA, and this preset value is the standby current value. When the current value is greater than this preset value, the surface load operates normally; when it is less than or equal to this preset value, the surface load is not operating or is in standby mode, and in this case, power-off will not affect the load.

[0050] Specifically, the relay model is G2R-2-SND. This relay can be a normally closed relay. The power-off signal can be a high-level signal, which causes the relay to disconnect for a preset time (such as 3s) and puts the plug module 190 in a power-off state, thus avoiding accidental contact. The state is re-judged after the preset time.

[0051] In some preferred embodiments, a rectifier 112 is also provided within the adapter housing 110. The rectifier 112 is connected to the current detection device 130 and is configured to supply DC power to the current detection device 130. Specifically, the rectifier 112 can utilize a rectifier bridge circuit to step down the voltage, switching the 220V AC power to 5V DC power to supply the current detection device 130, thereby achieving DC power supply for the current detection device 130. Preferably, the rectifier 112 can be a diode rectifier bridge, such as GBU806, GBU1006, KBU808, KBU1010, etc., which has strong versatility and a wide voltage and current range.

[0052] See Figure 4The control principle of the safety sensor adapter 100 is described in detail below. First, 220V AC power is stepped down by the rectifier 112 through the rectifier bridge and then supplied to the current detection device 130 as DC power. The current detection device 130 can detect whether there is current in the socket module 190, that is, detect the current value of the socket module 190. When a normal current value is detected in the socket module 190, it indicates that the load appliance is in a working energized state. At this time, the relay is continuously energized, thereby controlling the socket module 190 to be in an energized state, realizing the power supply of the load appliance. When the plug-in module 190 detects no current or a low current value, it indicates that the load appliance is in a non-working, power-off, or standby state. At this time, it is necessary to further detect the obstruction signal on the front of the adapter housing 110 through the sensing radar 150. When there is obstruction on the front of the adapter housing 110 (i.e., obstruction signal is detected), it indicates a risk of electric shock. At this time, the relay is disconnected, thereby controlling the plug-in module 190 to be in a power-off state to avoid electric shock. When there is no obstruction on the front of the adapter housing 110 (i.e., no obstruction signal is detected), it indicates no risk of electric shock. At this time, the relay remains energized to power on the load appliance.

[0053] In some preferred embodiments, there are multiple socket positions 111, socket modules 190, current detection devices 130, and power-off control devices 170. Multiple socket modules 190 correspond to multiple socket positions 111, multiple current detection devices 130 are connected to multiple socket modules 190 and configured to detect the current value of each socket module 190, and multiple power-off control devices 170 are connected to multiple socket modules 190 and configured to independently control the power on / off status of each socket module 190. Specifically, there can be two socket positions 111, including one 3-hole socket and one 2-hole socket. Two socket modules 190 correspond to two socket positions 111, two current detection devices 130 correspond to two socket modules 190 to realize separate current detection of the two socket modules 190, and two power-off control devices 170 control the power on / off status of the two socket modules 190, thus forming a 5-hole, 2-position structure.

[0054] See Figure 5 The control principle of the 5-hole 2-position structure will be further described below. Specifically, the two socket modules 190 can be designated as K1 and K2 modules respectively. Module K1 corresponds to the 3-hole socket, and module K2 corresponds to the 2-hole socket. Modules K1 and K2 can be powered separately. The two relays can be designated as J1 and J2 relays respectively, and relays J1 and J2 can control the power supply to modules K1 and K2 respectively. Similarly, the two current detection devices 130 can be designated as L1 current sensor and L2 current sensor respectively, and current sensors L1 and L2 can detect the current values ​​of modules K1 and K2 respectively.

[0055] In actual use, the 220V AC power is first stepped down by the rectifier 112 through the rectifier bridge and then supplied to the current detection device 130 as DC power. The L1 current sensor detects the current value of the K1 module. If the current value detected by the K1 module is large (greater than the preset value), the J1 relay is controlled to remain energized, so that the K1 module is continuously powered on. If the current value detected by the K1 module is small or zero (less than the preset value), the J1 relay is switched on and off based on the detection result of the sensing radar 150. If the sensing radar 150 detects an obstruction signal (the front of the adapter housing 110 is obstructed), the J1 relay is disconnected for 3 seconds and then re-evaluated after 3 seconds. If the sensing radar 150 does not detect an obstruction signal (the front of the adapter housing 110 is unobstructed), the J1 relay remains energized, so that the K1 module is continuously powered on. Similarly, the L2 current sensor detects the current value of the K2 module. If the K2 module detects a large current value, it controls the J2 relay to remain continuously engaged, thus continuously powering on the K2 module. If the K2 module does not detect a small current value, the J2 relay is switched on and off based on the detection result of the sensing radar 150. If the sensing radar 150 detects an obstruction signal (the front of the adapter housing 110 is obstructed), the J2 relay is disconnected for 3 seconds and then re-evaluated after 3 seconds. If the sensing radar 150 does not detect an obstruction signal (the front of the adapter housing 110 is unobstructed), the J2 relay remains engaged, thus continuously powering on the K2 module.

[0056] Please continue reading Figure 2 and Figure 3 In some preferred embodiments, an electrical control board 113 is also provided within the adapter housing 110. A current detection device 130 is disposed on the electrical control board 113, a sensing radar 150 is disposed on the side of the electrical control board 113 near the hole 111, and a power-off control device 170 is disposed on the electrical control board 113 and electrically connected to both the electrical control board 113 and the socket module 190, configured to control the power supply status between the socket module 190 and the electrical control board 113. Specifically, the electrical control board 113 may be a printed circuit board connected to an external circuit (e.g., an external rail or external power grid). The current detection device 130 and the relay are both fixedly disposed on the electrical control board 113, and the rectifier 112 may be integrated on the surface of the electrical control board 113. The socket module 190 may be an electrical connection structure including a copper plate socket, the specific construction of which can refer to the socket structure in existing sockets.

[0057] It should be noted that the communication connection of the volume in this embodiment can be an electrical connection, that is, the electrical and communication connection between them can be achieved through the circuit leads on the control board. The specific connection principle can be referred to the existing printed circuit board.

[0058] In some embodiments, the adapter housing 110 includes a rear cover 114 and a front panel 115. The rear cover 114 has a mounting groove 116, and an electronic control board 113 is disposed within the mounting groove 116. A current detection device 130, a power-off control device 170, and a socket module 190 are all disposed on the side surface of the electronic control board 113 facing the opening of the mounting groove 116. The front panel 115 covers the opening of the mounting groove 116. The front panel 115 is provided with a hole 111 and a clearance hole 118. A sensing radar 150 is disposed on the front panel 115 and corresponds to the clearance hole 118. Specifically, the front panel 115 can be a rectangular panel, with the hole 111 disposed in the middle of the rectangular panel and the clearance hole 118 disposed at the corner of the rectangular panel, thereby avoiding interference between the sensing radar 150 and the socket module 190. By providing the clearance hole 118, the sensing effect of the sensing radar 150 can be improved.

[0059] In some embodiments, the adapter housing 110 further includes a shielding panel 117, which is disposed on the side of the front panel 115 away from the mounting groove 116 and is detachably connected to the rear cover 114. The shielding panel 117 is also provided with openings corresponding to the holes 111, configured to shield the front panel 115 and the rear cover 114. Specifically, the shielding panel 117 can shield the connection between the front panel 115 and the rear cover 114, thereby preventing external dust or debris from entering and providing protection. At the same time, the shielding panel 117 is thin enough to directly shield the clearance hole 118, thereby maintaining a uniform appearance as much as possible without affecting the sensing effect of the sensing radar 150, and preventing external debris or dust from affecting the performance of the sensing radar 150.

[0060] In some embodiments, an indicator light 119 is also provided on the front side of the adapter housing 110. The indicator light 119 is electrically connected to the electronic control board 113 and is configured to illuminate when power is supplied between the plug-in module 190 and the electronic control board 113. Specifically, the indicator light 119 can be linked with a relay. When the relay is energized, the indicator light 119 illuminates, and when the relay is de-energized, the indicator light 119 turns off.

[0061] In some embodiments, a guide arm insert (not shown) is also provided on the back of the adapter housing 110. The guide arm insert is connected to the electronic control board and is configured to be inserted into the conductive rail. Specifically, the safety sensor adapter 100 can be applied to a safety sensor rail socket, thereby achieving an electrical connection with the conductive rail by providing a guide arm insert on the back of the adapter housing 110. For the specific structure of the conductive rail and the principle of electrical connection, refer to existing rail sockets.

[0062] In some embodiments, the back of the adapter housing 110 is also provided with conductive holes (not labeled in the figure). The conductive holes are connected to the control board and are configured to connect external wires. Specifically, the conductive holes have a three-hole structure with built-in conductive sheets.

[0064] In summary, the safety sensor adapter 100 provided in this embodiment of the present invention has a hole 111 on the front of the adapter housing 110, and the adapter housing 110 contains a socket module 190, a current detection device 130, a sensing radar 150, and a power-off control device 170. The socket module 190 corresponds to the hole 111, thereby enabling it to connect to the load-side plug inserted into the hole 111. The current detection device 130 can detect the current value of the socket module 190, while the sensing radar 150, when close to the front of the adapter housing 110, can detect any obstruction signals. The power-off control device 170 can control the socket module 190 to disconnect from the power supply when there is no current in the socket module 190 and the front of the adapter housing 110 is obstructed, thereby achieving safety protection for the adapter. Compared with the prior art, the safety sensor adapter 100 provided by this invention uses the sensing radar 150 to determine the approaching object, providing accurate and reliable detection. The additional current detection device 130 can detect the current value and determine whether a load appliance is in use. When no load appliance is in use and a child, pet or other object is near the adapter, the power can be cut off by the power-off control device 170. This can effectively prevent children from accidentally touching the switch and causing electric shock. At the same time, the power should be cut off when the load appliance is not in use, which can also prevent accidental power cut-off when in use. This can protect electrical safety without affecting the user experience.
