Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In the absence of further limitations, the elements defined by the phrase "include..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Figure 1 The structure of a power adapter according to an embodiment of the present invention is schematically shown.

[0026] refer to Figures 1 and 2 As shown, the power adapter includes a power plug-in unit 10 and a power extraction unit 20 .

[0027] The plug-in portion 10 is cylindrical and is used for plugging in an external electrical appliance to draw power.

[0028] The power drawer 20 is a sheet-shaped device located at the bottom of the power plug 10. It is equipped with a live wire conductive sheet 51, a neutral wire conductive sheet 52, and a ground wire conductive sheet 53, which are electrically connected to the plug-in unit 10's external electrical connector pins. The live wire conductive sheet 51 and the neutral wire conductive sheet 52 are located symmetrically on either side of the power drawer 20, about the center of the plug-in unit 10. The power drawer 20 can be inserted into a live rail to draw power. The positions of the live wire conductive sheet 51, the neutral wire conductive sheet 52, and the ground wire conductive sheet 53 match the positions of the live, neutral, and ground wires in the live rail, respectively.

[0029] Accommodation slots 21 are provided on both sides of the power taking portion 20 , and the positions and shapes of the live wire conductive sheet 51 and the neutral wire conductive sheet 52 are adapted to each other.

[0030] A circular adjustment ring 31 is provided at the lower portion of the plug-in unit 10 . By rotating the adjustment ring 31 clockwise or counterclockwise, the contacts of the live wire conductive sheet 51 and the neutral wire conductive sheet 52 can be driven to retract into the receiving groove 21 or expand outward.

[0031] Figures 2 to 6 The structure of the power supply adapter and the power supply rail according to an embodiment of the present invention is schematically shown.

[0032] refer to Figures 2 to 4 As shown, a space is provided at the bottom of the power plug portion 10 of the power adapter for arranging an adjustment mechanism for the power supply adapter and the power rail power supply structure.

[0033] The power supply structure includes: a live wire conductive sheet 51 electrically connected to the live wire pin of the power adapter, a neutral wire conductive sheet 52 electrically connected to the neutral wire pin of the power adapter, and an adjustment mechanism.

[0034] In this embodiment, the structure of the neutral conductive sheet 52 is identical to that of the live conductive sheet 51. The neutral conductive sheet 52 and the live conductive sheet 51 are symmetrically arranged relative to the hinge axis between the adjustment member and the power plug 10. The following description uses the adjustment mechanism to adjust the live conductive sheet 51 between the energized and de-energized states. The adjustment method for adjusting the neutral conductive sheet 52 between the energized and de-energized states can be similarly described for the live conductive sheet 51.

[0035] The adjustment mechanism includes an adjustment member and a positioning member 41. A live wire contact 510 is provided at the first end of the live wire conductive sheet 51, and the second end abuts the positioning member 41. The live wire contact 510 is configured to abut the live wire of the power rail when powered on, and to reside within the power supply unit 20 of the power adapter when powered off. The adjustment member is configured to drive the live wire conductive sheet 51 to rotate about the positioning member 41, switching between the powered and de-powered states.

[0036] The positioning member 41 is fixedly connected to the plug-in portion 10 of the power adapter and is disposed on an edge of the bottom plate 11 of the plug-in portion 10 .

[0037] The adjusting member is hinged to the plug-in part 10 of the power adapter, and the adjusting member includes a circular adjusting ring 31, a connecting rod 32 and a swinging member 33. The adjusting ring 31 is hinged to the plug-in part 10. The connecting rod 32 is arranged inside the adjusting ring 31, and the connecting rod 32 is butterfly-shaped. The two ends of the connecting rod 32 are respectively fixedly connected to the inner wall of the adjusting ring 31, and the midpoint of the connecting rod 32 coincides with the center of the circle of the adjusting ring 31. The first end of the swinging member 33 is fixedly connected to the midpoint of the connecting rod 32, and the second end of the swinging member 33 is arranged relative to the positioning member 41, and can abut against the live wire conductive sheet 51. The swinging member 33 can move the live wire conductive sheet 51 to rotate around the deepest part of the positioning groove 411, so that the live wire contact 510 abuts against the live wire of the power track when the power is on, and is located in the receiving groove 21 of the power taking part 20 of the power adapter when the power is off.

[0038] The adjustment member is positioned above the base plate 11, and the power extraction unit 20 is positioned below it. The base plate 11 of the power insertion unit 10 is provided with a through hole 111. The first free end 511 of the live conductive sheet 51 is positioned below the through hole 111, while the second free end 513 is positioned above the through hole. The power extraction unit 20 is provided with a receiving slot 21 that matches the position and shape of the first free end 511 of the live conductive sheet 51.

[0039] In this embodiment, the positioning member 41 is provided with a V-shaped positioning groove 411, and the second end of the swinging member 33 may also be provided with a slot 331 for accommodating the elastic member 34. The live conductive sheet 51 is U-shaped, with a live contact 510 provided at the first free end 511, a second free end 513 abutting the elastic member 34, and a bottom edge 512 of the live conductive sheet 51 abutting the deepest part of the positioning groove 411. The elastic member 34 applies force to the live conductive sheet 51, ensuring that it remains in contact with the positioning groove 411. This also provides a certain degree of elasticity when the swinging member 33 rotates the live conductive sheet 51, resulting in smoother rotation. In this embodiment, the elastic component 34 is a compression spring, which is inserted into the slot 331. The first end of the compression spring abuts against the bottom of the slot 331, and the second end abuts against the second free end 513 of the live wire conductive sheet 51. The second free end 513 of the live wire conductive sheet 51 is provided with a protrusion, which can be inserted into the spring coil of the compression spring to keep the live wire conductive sheet 51 and the compression spring in abutment.

[0040] refer to Figure 5As shown, by rotating the adjustment ring 31 clockwise, the swinging member 33, which is fixedly connected to the adjustment ring 31 via the connecting rod 32, moves the second free end 513 of the live wire conductive plate 51 counterclockwise. Since the bottom edge 512 of the live wire conductive plate 51 is constrained in the V-shaped positioning groove 411 and abuts the deepest part of the V-shaped positioning groove 411, the live wire conductive plate 51 rotates counterclockwise about the deepest part of the positioning groove 411, thereby causing the first free end 511 of the live wire conductive plate 51 to extend outward from the accommodating groove 21 of the power extraction unit 20. At this time, if the power extraction unit 20 is inserted into the power rail, the live wire contact 510 will abut the live wire in the power rail, causing the external appliance pins of the plug-in unit 10 to be energized.

[0041] On the contrary, reference Figure 6 As shown, by rotating the adjustment ring 31 counterclockwise, the live conductive piece 51 rotates clockwise around the deepest point of the positioning groove 411, thereby retracting the first free end 511 of the live conductive piece 51 from the outside of the power extraction unit 20 into the accommodating groove 21. At this point, the live contact 510 separates from the live wire in the power rail, disconnecting the power supply pins of the external appliance on the power supply unit 10.

[0042] In other embodiments, the positioning member 41 can also be hinged to the live conductive sheet 51, as long as the live conductive sheet 51 can swing along the hinge point or positioning point. The swinging member 33 can also be hinged to the live conductive sheet 51. The elastic member 34 can also be a torsion spring, spring, pneumatic cylinder, hydraulic cylinder, etc.

[0043] The bottom plate 11 is also provided with a limiter 112 for limiting the range of motion of the connecting rod 32. The limiters 112 are arc-shaped and are two oppositely arranged ones, which are arranged at the edge of the bottom plate 11, and the connecting rod 32 is located between the ends of the two limiters 112.

[0044] The power supply adapter of the track socket of the present invention and the power supply structure of the energized track can control whether the live wire conductive piece is in contact with the live wire of the energized track by operating the adjustment mechanism. When the position of the power adapter needs to be adjusted, the adjustment mechanism can be operated in the forward direction to prevent the live wire conductive piece from contacting the live wire of the energized track, so that the power adapter is powered off when sliding on the energized track; when the power adapter is in place, the adjustment mechanism can be operated in the reverse direction to make the live wire conductive piece contact with the live wire of the energized track, so that the live wire pin of the power adapter is energized. Similarly, the first end of the neutral wire conductive piece 52 is provided with a neutral wire contact 520, and the second end is in contact with another corresponding positioning member 41. The neutral wire contact 520 is configured to be in contact with the neutral wire of the energized track in the energized state, and is located in the power supply unit 20 of the power adapter in the power-off state. The adjustment member is also configured to drive the neutral wire conductive piece 52 to switch between the energized and power-off states.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned examples, or make equivalent replacements for some of the technical features therein.
