Description

Technical Field

[0001] The utility model relates to the technical field of socket safety structures, in particular to an output socket of a portable energy storage power supply. Background Art

[0002] Portable energy storage power supplies can provide 220V AC power to various electrical appliances without an AC power grid, providing convenience for users. Since portable energy storage power supplies are limited by the need for "portability", the size and weight of portable energy storage power supplies are as small as possible, which makes the battery capacity inside the energy storage power supply relatively limited, that is, the energy that portable energy storage power supplies can store is relatively limited. Energy saving has become an important requirement for portable energy storage power supplies. At present, the energy-saving mode of portable energy storage power supplies is generally to detect the output power. When the output power is detected to be very low or 0 for a continuous period of time, the inverter output will be stopped or the power will be automatically shut down to reduce power consumption.

[0003] In the actual use of portable energy storage power supply, if the plug of the load appliance is not fully plugged into the output socket of the portable energy storage power supply, there are two undesirable situations. One situation is: the contact area between the plug of the load appliance and the conductive metal reed inside the output socket is insufficient, which will cause the temperature of the metal reed to be too high, causing the socket to deform, damage, or even cause a safety accident. The other situation is: the portable energy storage power supply outputs a small current or an intermittent output current, which causes the portable energy storage power supply to misjudge, and then stop the inverter output current or the portable energy storage power supply automatically shuts down. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an output socket of a portable energy storage power supply, which can ensure that the portable energy storage power supply can operate when the plug and the socket are fully plugged in.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an output socket of a portable energy storage power supply, comprising a socket body and a trigger assembly; the socket body has a plug end and a trigger end, and a through groove extending from the plug end to the trigger end is provided on the socket body;

[0006] The trigger assembly includes an in-position detection rod and a micro switch, wherein the in-position detection rod is slidably disposed in a through slot, the micro switch is disposed at a trigger end of the socket body, and a trigger switch of the micro switch is located in the through slot, and the micro switch is electrically connected to a main control module of the portable energy storage power supply;

[0007] When the plug is not plugged into the plug-in end of the socket body or the plug is not completely plugged into the plug-in end of the socket body, the in-place detection rod will not press the micro switch, so that the switch contact of the micro switch is in a disconnected state;

[0008] When the plug is fully plugged into the plug-in end of the socket body, the plug drives the in-place detection rod to press the micro switch, so that the switch contacts of the micro switch are in a connected state.

[0009] Furthermore, the trigger assembly also includes an elastic member, one end of the elastic member abuts against the in-place detection rod, and the other end of the elastic member abuts against the micro switch.

[0010] Further, when the plug is not plugged into the plug-in end of the socket body or the plug is not completely plugged into the plug-in end of the socket body, the end of the in-position detection rod away from the micro switch extends out of the plug-in end of the socket body;

[0011] When the plug is completely plugged into the plugging end of the socket body, the end of the in-position detection rod away from the micro switch is flush with the end surface of the plugging end of the socket body.

[0012] Furthermore, the maximum extension amount of the in-position detection rod, at one end away from the micro switch, extending out of the plug-in end of the socket body is 2 mm to 3 mm.

[0013] Furthermore, a limiting cavity communicated with the through slot is arranged in the plug-in end of the socket body, and a flange movable in the limiting cavity is arranged on the rod body of the in-position detection rod.

[0014] Furthermore, the output socket of the portable energy storage power supply further includes an NTC thermistor, which is arranged on the live metal spring of the socket body, and is electrically connected to the main control module of the portable energy storage power supply.

[0015] The beneficial effect of the utility model is that a trigger component is added to the socket body, and the plug is used to drive the detection rod to press the micro switch to help the portable energy storage power supply determine whether the socket body and the plug are fully plugged in. This ensures that the portable energy storage power supply can operate when the plug and the socket are fully plugged in. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Portable energy storage power supplies can provide 220V AC power to various electrical appliances without an AC power grid, providing convenience for users. Since portable energy storage power supplies are limited by the need for "portability", the size and weight of portable energy storage power supplies are as small as possible, which makes the battery capacity inside the energy storage power supply relatively limited, that is, the energy that portable energy storage power supplies can store is relatively limited. Energy saving has become an important requirement for portable energy storage power supplies. At present, the energy-saving mode of portable energy storage power supplies is generally to detect the output power. When the output power is detected to be very low or 0 for a continuous period of time, the inverter output will be stopped or the power will be automatically shut down to reduce power consumption.

[0024] In the actual use of portable energy storage power supply, if the plug of the load appliance is not fully plugged into the output socket of the portable energy storage power supply, there are two undesirable situations. One situation is: the contact area between the plug of the load appliance and the conductive metal reed inside the output socket is insufficient, which will cause the temperature of the metal reed to be too high, causing the socket to deform, damage, or even cause a safety accident. The other situation is: the portable energy storage power supply outputs a small current or an intermittent output current, which causes the portable energy storage power supply to misjudge, and then stop the inverter output current or the portable energy storage power supply automatically shuts down.

[0025] Based on this, the present application provides an output socket of a portable energy storage power supply, which can solve the problem that the portable energy storage power supply will still operate when the plug and the socket body are not fully plugged in.

[0026] Please refer to Figure 1 and Figure 2 As shown, the utility model is an output socket of a portable energy storage power supply, comprising a socket body 1 and a trigger assembly 2; the socket body 1 has a plug end and a trigger end, and the socket body 1 is provided with a through slot 11 extending from the plug end to the trigger end;

[0027] The trigger assembly 2 includes an in-place detection rod 21 and a micro switch 22, wherein the in-place detection rod 21 is slidably disposed in the through slot 11, the micro switch 22 is disposed at the trigger end of the socket body 1, and the trigger switch of the micro switch 22 is located in the through slot 11, and the micro switch 22 is electrically connected to the main control module of the portable energy storage power supply;

[0028] When the plug is not plugged into the plug-in end of the socket body 1 or the plug is not completely plugged into the plug-in end of the socket body 1, the in-place detection rod 21 will not press the micro switch 22, so that the switch contact of the micro switch 22 is in an open state;

[0029] When the plug is completely plugged into the plug end of the socket body 1 , the plug will drive the in-place detection rod 21 to press the micro switch 22 , so that the switch contact of the micro switch 22 is in a connected state.

[0030] Working principle: There are two situations when the in-place detection rod 21 moves in the through slot 11 toward the micro switch 22. The first situation is that when the in-place detection rod 21 is not subject to external force, the in-place detection rod 21 is completely located in the through slot 11. A push rod that can extend into the through slot 11 is provided on the plug. During the plug-in connection process between the plug and the socket body 1, the push rod on the plug extends into the through slot 11. If the plug and the socket body 1 are not fully plugged in, the push rod on the plug is not sufficient to drive the in-place detection rod 21 to press the trigger switch of the micro switch 22, so that the switch contacts of the micro switch 22 are in a connected state. If the plug and the socket body 1 are fully plugged in, the push rod on the plug can drive the in-place detection rod 21 to press the trigger switch of the micro switch 22, so that the switch contacts of the micro switch 22 are in a connected state.

[0031] The second situation: when the in-place detection rod 21 is not subjected to external force, the end of the in-place detection rod 21 away from the micro switch 22 extends out of the plug-in end of the socket body 1. During the plug-in process between the plug and the socket body 1, as the plug is continuously inserted into the socket body 1, the plug will push the in-place detection rod 21. If the plug and the socket body 1 are not fully plugged in, the plug is not sufficient to drive the in-place detection rod 21 to press the trigger switch of the micro switch 22, so that the switch contact of the micro switch 22 is in a connected state. If the plug and the socket body 1 are fully plugged in, the plug can drive the in-place detection rod 21 to press the trigger switch of the micro switch 22, so that the switch contact of the micro switch 22 is in a connected state.

[0032] Please refer to Figure 1 As shown, further, the trigger assembly 2 also includes an elastic member 23 , one end of the elastic member 23 abuts against the in-position detection rod 21 , and the other end of the elastic member 23 abuts against the micro switch 22 .

[0033] It can be seen from the above description that after the plug is separated from the socket body 1, the elastic member 23 can automatically drive the in-position detection rod 21 to reset, thereby eliminating the need for manual reset operations.

[0034] Please refer to Figure 1 and Figure 2As shown, further, when the plug is not plugged into the plug-in end of the socket body 1 or the plug is not completely plugged into the plug-in end of the socket body 1, the end of the in-place detection rod 21 away from the micro switch 22 extends out of the plug-in end of the socket body 1;

[0035] When the plug is completely plugged into the plugging end of the socket body 1 , the end of the in-position detection rod 21 away from the micro switch 22 is flush with the end surface of the plugging end of the socket body 1 .

[0036] From the above description, it can be seen that when the in-place detection rod 21 is used, the in-place detection rod 21 can extend out of the plug-in end of the socket body 1 without being subjected to external force, and the end face of the socket can directly push the in-place detection rod 21 to move toward the micro switch 22, which can eliminate the need for a push rod on the plug to push the in-place detection rod 21, thereby allowing the socket body 1 to adapt to plugs from a variety of manufacturers.

[0037] Furthermore, the maximum extension of the end of the in-position detection rod 21 away from the micro switch 22 from the plug end of the socket body 1 is 2mm to 3mm. Among them, the preferred maximum extension of the in-position detection rod 21 from the plug end of the socket body 1 is 2.5mm.

[0038] From the above description, it can be seen that the maximum extension amount of the in-place detection rod 21 from the plug-in end of the socket body 1 is controlled to be 2mm to 3mm. This can ensure whether the plug and the socket body 1 are fully plugged in, while avoiding the extension amount of the in-place detection rod 21 extending too long from the plug-in end of the socket body 1, which increases the accidental breakage rate of the in-place detection rod 21.

[0039] Please refer to Figure 1 As shown, further, a limiting cavity 12 communicating with the through slot 11 is provided in the plug-in end of the socket body 1 , and a flange 211 movable in the limiting cavity 12 is provided on the rod body of the in-position detection rod 21 .

[0040] It can be seen from the above description that the cooperation between the limiting cavity 12 and the flange 211 can prevent the in-place detection rod 21 from overpressing the micro switch 22 or the in-place detection rod 21 from falling out of the socket body 1 .

[0041] Please refer to Figure 1 As shown, further, the output socket of the above-mentioned portable energy storage power supply also includes an NTC thermistor 3, which is arranged on the live wire metal spring of the socket body 1, and the NTC thermistor 3 is electrically connected to the main control module of the portable energy storage power supply.

[0042] From the above description, it can be seen that the main control module of the portable energy storage power supply can monitor the temperature of the socket body 1 in real time by using the NTC thermistor 3. When the temperature of the socket body 1 reaches the threshold, the main control module of the portable energy storage power supply can promptly control the inverter of the portable energy storage power supply to cut off the output, thereby ensuring safe use.
