The present application provides a Power adapter 10. Referring to fig. 1, fig. 1 is a schematic view of an application environment of a power adapter according to an embodiment of the application. The power adapter 10 is a power supply power conversion device of the electronic device 30. Typically, the power adapter 10 may convert an ac voltage to a dc voltage. For example, the power adapter 10 is plugged into the socket 50, receives an ac voltage output from the socket 50, and converts the received ac voltage into a dc voltage, which is used to charge the electronic device 30 powered by a mobile phone, a computer, or the like. It will be appreciated that the application environment schematic of the power adapter 10 is merely helpful in understanding the application of the power adapter 10, and should not be construed as a limitation of the power adapter 10 provided by the present application.

Referring to fig. 2, fig. 3 and fig. 4 together, fig. 2 is a schematic diagram of a power adapter according to an embodiment of the application in one state; FIG. 3 is a schematic diagram of a power adapter according to another embodiment of the present application; fig. 4 is a schematic diagram of a power adapter according to another embodiment of the present application. The power adapter 10 includes an adapter body 100, pins 200, a first cover 300, and a second cover 400. The pins 200 are connected to the end face 110 of the adapter body 100, and the first cover 300 and the second cover 400 are rotatably connected to the adapter body 100, respectively. When the first cover 300 and the second cover 400 are closed, the pins 200 are covered; when the first cover 300 and the second cover 400 are opened relatively, the pins 200 are exposed, and the surface (the covering surface 320) of the first cover 300 facing the pins 200 and the surface 420 of the second cover 400 facing the pins 200 together form a plugging surface of the power adapter 10.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.

The adapter body 100 is a part for realizing the voltage conversion function of the power adapter 10. The adapter body 100 generally includes a circuit board for voltage conversion, and in addition, the adapter body 100 may further include a housing or the like that accommodates the circuit board.

The pin 200 is made of metal, and the pin 200 is plugged into the socket 50 for receiving the ac voltage provided by the socket 50. The number of pins 200 may be, but is not limited to, two, and in this embodiment, the number of pins 200 is two. The two pins 200 are opposite and spaced apart. The pins 200 may be, but are not limited to, elongated. The end of the pin 200 facing away from the body of the socket 50 is curved to facilitate insertion of the pin 200 into the socket 50. When the pin 200 is inserted into the socket 50 to receive a first voltage, a circuit board disposed in the adapter body 100 is electrically connected to the pin 200 to receive the first voltage transmitted by the pin 200, and the circuit board is used for converting the first voltage into a second voltage.

The first cover 300 and the second cover 400 are respectively rotatably connected to the adapter body 100, a manner of rotatably connecting the first cover 300 and the adapter body 100 will be described in detail later, and a manner of rotatably connecting the second cover 400 and the adapter body 100 will be described in detail later.

The power adapter 10 has a first state (see fig. 2), a second state (see fig. 4), and an intermediate state (see fig. 3) between the first state and the second state. When the power adapter 10 is in the first state, the first cover 300 and the second cover 400 are closed, and the pins 200 are completely covered. When the power adapter 10 is in the second state, the first cover 300 and the second cover 400 are both completely opened with respect to the adapter body 100, and the pins 200 are completely exposed. When the power adapter 10 is in the third state, the first cover 300 is partially opened with respect to the adapter body 100, and the second cover 400 is partially opened with respect to the adapter body 100.

In one embodiment, the adapter body 100 has an end face 110, a first side face 120, and a second side face 130. The end face 110 is a surface of the power adapter 10 on which the pins 200 are disposed, the first side face 120 and the second side face 130 are disposed opposite to each other, the first side face 120 and the second side face 130 are both connected to the end face 110, and the first side face 120 and the second side face 130 are both located on the same side of the end face 110.

When the first cover 300 and the second cover 400 are closed, the first cover 300 and the second cover 400 are both positioned on the same side of the end face 110 to form a box for covering the pins 200. When the first cover 300 and the second cover 400 are opened relatively, the first cover 300 and the second cover 400 may also be fixed on two opposite sides of the adapter body 100, specifically, the first cover 300 is disposed on the side where the first side 120 is located, the second cover 400 is disposed on the side where the second side 130 is located, and the first cover 300 and the second cover 400 are fixed. The surface of the first cover 300 facing the pin 200 and the surface 420 of the second cover 400 facing the pin 200 together form a plugging surface of the power adapter 10.

The mating surface of the power adapter 10 is a surface that mates with the socket 50 when the pins 200 of the power adapter are inserted into the socket 50, and the mating surface satisfies the requirements of safety regulations of the power adapter 10. When the plug 200 of the power adapter 10 is inserted into the socket 50, a surface that merely mates with the socket 50 but does not meet the safety regulations of the power adapter 10 cannot be referred to as a plug surface of the power adapter 10. Specifically, for the power adapter 10, when the pins 200 of the power adapter 10 are inserted into the sockets 50, in order to avoid injury to a user caused by leakage of electric energy from the sockets 50 through the pins 200, an edge of the pins 200 closest to the plugging surface needs to be greater than or equal to a predetermined distance (also referred to as a safety distance), for example, the predetermined distance is 6.5mm for a power adapter suitable for china. For power adapters suitable for other countries, the distance is other value. In the schematic view of the present embodiment, when the first cover 300 and the second cover 400 are relatively opened, a distance between the leftmost edge of the pin 200 and the surface of the first cover 300 facing away from the adapter body 100 (i.e., the leftmost surface of the first cover 300) is greater than or equal to the preset distance; likewise, a surface of the pin 200 that is furthest to the right from the second cover 400 that faces away from the adapter body 100 (i.e., a surface of the second cover 400 that is furthest to the right) is greater than or equal to the predetermined distance.

In the conventional art, the end face of the adapter body provided with the pins 200 in the power adapter 10 constitutes the plugging face of the power adapter, in other words, the plugging face of the power adapter 10 in the conventional art is formed only by the end face of the adapter body 100 provided with the pins 200, and therefore, in the conventional art, the thickness of the adapter body is generally thick. For example, in order to meet the requirements of safety regulations of the power adapter 10, the width of the plugging surface of the power adapter 10 is set to 22mm. Since the plugging surface of the power adapter body 100 is formed only by the end surface of the adapter body 100 where the pins 200 are provided in the conventional art, the thickness of the adapter body 100 in the power adapter 10 is the width of the plugging surface, and thus the thickness of the adapter body 100 of the power adapter 10 in the conventional art is 22mm. In the power adapter 10 of the present application, the surface 320 of the first cover 300 facing the pin 200 and the surface 420 of the second cover 400 facing the pin 200 together form a plugging surface of the power adapter 10, that is, the sum of the thickness d1 of the adapter body 100, the thickness d2 of the first cover 300, and the thickness d3 of the second cover 400 is equal to 22mm. In other words, the end face of the adapter body 100 where the pins 200 are provided in the power adapter 10 of the present application is only a part of the plugging face of the power adapter 10, and the thickness d1 of the adapter body 100 in the power adapter 10 of the present application is necessarily smaller than the total width (22 mm in the example) of the plugging face. It can be seen that the thickness of the adapter body 100 in the power adapter 10 of the present application is thinner than that of the power adapter in the conventional art.

Compared to the conventional art, in the power adapter 10 provided by the present application, the first cover 300 and the second cover 400 are rotatably connected to the adapter body 100, and when the first cover 300 and the second cover 400 are closed, the pins 200 are covered, so that the pins 200 can be protected from being damaged and other objects can be prevented from being damaged by the pins 200. When the power adapter 10 needs to be used, the first cover 300 and the second cover 400 are opened relatively to expose the pins 200, and the power adapter 10 can be used normally. Further, when the user uses the power adapter 10, the pins 200 are exposed by relatively opening the first cover 300 and the second cover 400, the surface 320 of the first cover 300 facing the pins 200, the surface 420 of the second cover 400 facing the pins 200, and the end face 110 of the adapter body 100 together form the plugging surface of the power adapter 10, and compared with the plugging surface of the power adapter in the power adapter of the conventional technology, which is formed only by the end face of the adapter body provided with the pins, the thickness of the adapter body 100 in the power adapter 10 of the present application can be made thinner, thereby facilitating the miniaturization of the power adapter 10.

The first cover 300 has a receiving groove, and for convenience of description, the receiving groove of the first cover 300 is named as a second receiving groove 330. The second receiving groove 330 is configured to receive a second fixing portion 521, so as to fix the first sub-bracket 520 to the first cover 300. The first cover 300 has a cover surface 320 and a first surface 310. The cover surface 320 is a surface of the first cover 300 that covers the adapter body 100. In other words, when the first cover 300 is closed with respect to the adapter body 100, the cover surface 320 faces the end surface 110 of the adapter body 100; when the first cover 300 is opened with respect to the adapter body 100, the cover surface 320 faces the pins. The first surface 310 is an outer surface that is coupled to the mating surface 320. The first surface 310 forms an outer surface of the first cover 300 when the first cover 300 is closed relative to the adapter body 100. The second receiving groove 330 is disposed on the covering surface 320 and the first surface 310. The first cover 300 forms the second receiving groove 330 and has a stepped portion facing away from the covering surface 320, so as to limit the second fixing portion 521.

A gap is formed between the cambered surface 530b of the first connecting member 530 and the bottom wall of the second through groove 5221, so that the first connecting member 530 can rotate relative to the first pair.

In this embodiment, the second chute 532 is also an arc-shaped chute. The second chute 532 has a third end P3 and a fourth end P4 (see fig. 9). When the first cover 300 is closed relative to the adapter body 100, the third end P3 faces away from the adapter body 100 compared to the fourth end P4. The three ends are disposed away from the curved surface 530b as compared to the fourth end P4. The second shaft 550 passes through the second runner 532 and is slidable within the second runner 532 from the third end P3 to the fourth end P4 and is slidable within the second runner 532 from the fourth end P4 to the third end P3.

In an embodiment, the extending track of the first sliding groove 531 and the extending track of the second sliding groove 532 are located on a concentric circle. When the extending track of the first sliding groove 531 and the extending track of the second sliding groove 532 are located on the concentric circle, the first cover 300 can be ensured to rotate more smoothly than when the adapter body 100 rotates.

Referring to fig. 22 and 23, fig. 22 is a schematic parameter diagram of a part of components in the power adapter in a state; fig. 23 is a schematic parametric diagram of some of the components in the power adapter in another state. The first sliding groove 531 has a first end P1 and a second end P2 opposite to each other, when the first cover 300 and the second cover 400 are closed relatively, the first end P1 faces away from the first cover 300 compared to the second end P2, a distance between a center of the first end P1 and an inner wall of the first main support 510 is a, and a distance between a center of the first end P1 and an end face of the first main support 510 adjacent to the first cover 300 (i.e., an interface between the first main support 510 and the first sub-support 520) is B, where a is less than or equal to B.

In this embodiment, a is less than or equal to B, so that the first connector 530 does not protrude from the end face 110 of the adapter body 100 when the first cover 300 is closed with respect to the adapter body 100. When the first cover 300 and the second cover 400 are both closed with respect to the adapter body 100, it is ensured that the end face 110 of the adapter body 100 can be attached to the socket, so as to avoid damage to the human body caused by electric energy leakage of the socket. If the first cover 300 is closed relative to the adapter body 100, the first connecting member 530 protrudes from the end face 110 of the adapter body 100, a gap is formed between the outermost end of the first connecting member 530 and the end face 110 of the adapter body 100, and when the pins 200 of the power adapter 10 are inserted into the sockets, the electrical energy in the sockets leaks out through the gap, thereby causing injury to the human body.

Referring to fig. 22 and 24, fig. 24 is a schematic diagram of parameters of a part of components in the power adapter in yet another state. The distance between the center of the first sliding groove 531 and the center of the second sliding groove 532 is C, the distance between the center of the first shaft 540 and the outer surface of the adapter body 100 is D, and the distance between the center of the second shaft 550 and the corner of the first cover 300 adjacent to the adapter body 100 is E, wherein C is equal to or greater than d+e.

In this embodiment, C is greater than or equal to d+e, so that it is ensured that the first cover 300 does not touch the adapter body 100 when rotating relative to the adapter body 100, and it is ensured that the first cover 300 freely turns 0-180 ° relative to the adapter body 100, and a rotating path of the first cover 300 rotating relative to the adapter body 100 is a track marked Q in the figure.

Referring to fig. 30 and 31 in combination with the power adapter 10 according to any one of the foregoing embodiments, fig. 30 is a perspective view of a power adapter according to still another embodiment of the present application; fig. 31 is a cross-sectional view taken along line IV-IV in fig. 30. The power adapter 10 further includes a first magnetic member 700 and a second magnetic member 800. The first magnetic member 700 is carried on the first cover 300, and the second magnetic member 800 is carried on the second cover 400. When the first cover 300 and the second cover 400 are closed, the first magnetic member 700 and the second magnetic member 800 are attracted. When the second cover 400 is opened opposite to the second cover 400, the first magnetic member 700 and the second magnetic member 800 are attracted to each other, so that the first cover 300 and the second cover 400 are respectively fixed to opposite sides of the adapter body 100.

The first magnetic member 700 includes a first magnetic pole 710 and a second magnetic pole 720 which are disposed opposite to each other and have opposite polarities, the second magnetic member 800 includes a third magnetic pole 810 and a fourth magnetic pole 820 which are disposed opposite to each other and have opposite polarities, when the first cover 300 and the second cover 400 are closed, the first magnetic pole 710 is attracted to the third magnetic pole 810, and when the first cover 300 and the second cover 400 are opened relatively, the second magnetic pole 720 is attracted to the fourth magnetic pole 820.

In this embodiment, the first magnetic pole 710 is an S pole, and the second magnetic pole 720 is an N pole; accordingly, the third pole 810 is an N pole and the fourth pole 820 is an S pole. In further embodiments, the first pole 710 is an N pole and the second pole 720 is an S pole; accordingly, the third pole 810 is an S pole and the fourth pole 820 is an N pole.

When the first cover 300 and the second cover 400 are closed, the first magnetic pole 710 and the third magnetic pole 810 are attracted to each other, so that the first cover 300 and the second cover 400 are kept closed (refer to fig. 32, fig. 32 is a schematic diagram of magnetic relationships between the first magnetic member and the second magnetic member when the first cover and the second cover are kept closed). When one of the first cover 300 and the second cover 400 is opened, for example, when the first cover 300 is opened and the second cover 400 is not opened, refer to fig. 33, and fig. 33 is a schematic diagram of magnetic force relationship between the first magnetic member and the second magnetic member when the first cover is opened. The magnetic direction of the first magnetic member 700 in the opened first cover 300 is changed, so that the second magnetic pole 720 and the third magnetic pole 810 repel each other, so that the second cover 400 receives an inverted repulsive force, and the second cover 400 is inverted by the repulsive force. Therefore, the second cover 400 can be automatically turned over without operating the second cover 400. When the second cover 400 is turned over to a certain extent, the second magnetic pole 720 and the fourth magnetic pole 820 are attracted, so that the first cover 300 and the second cover 400 are fixed on two opposite sides of the adapter body 100. Referring to fig. 34, fig. 34 is a schematic diagram showing a magnetic relationship between the first magnetic member and the second magnetic member when the first cover and the second cover are opened and fixed on two sides of the adapter body.

When the first cover 300 and the second cover 400 are opened opposite to each other and are fixed to the opposite sides of the adapter body 100, the second magnetic pole 720 and the fourth magnetic pole 820 are attracted such that the first cover 300 and the second cover 400 are opened opposite to each other and remain fixed to the opposite sides of the adapter body 100, respectively. At this time, the first cover 300 is folded with the adaptor body 100, and the second cover 400 is folded with the adaptor body 100. When the first cover 300 and the adapter body 100 are closed, the direction of the magnetic pole of the first magnetic member 700 is changed, so that the first magnetic pole 710 and the fourth magnetic pole 820 repel each other, and the second cover 400 in the folded state is turned over by the turning force of the turning over relative to the adapter body 100, and the second cover 400 is turned over by the turning force. When the second cover 400 is turned over to a certain extent, the first magnetic pole 710 and the third magnetic pole 810 are attracted, so that the first cover 300 and the second cover 400 form a cover and are fixed on one side of the adapter body 100.

Referring to fig. 35 and 36, fig. 35 is a schematic view of a power adapter according to an embodiment of the application; fig. 36 is a schematic diagram of another state of the power adapter according to an embodiment of the present application. The power adapter 10 includes an adapter body 100, pins 200, a first cover 300, and a second cover 400. The pins 200 are connected to the adapter body 100, and the first cover 300 and the second cover 400 are rotatably connected to the adapter body 100, respectively. The first cover 300 is coplanar with the adapter body 100 when the first cover 300 is relatively closed with the adapter body 100, and the first cover 300 is laminated with the adapter body 100 when the first cover 300 is relatively folded with the adapter body 100. The first cover 300 is coplanar with the adapter body 100 when the second cover 400 is relatively closed with the adapter body 100, and the second cover 400 is stacked with the adapter body 100 when the second cover 400 is relatively folded with the adapter body 100. The pins 200 are covered when the first cover 300 and the second cover 400 are closed with respect to the adapter body 100, respectively, and the pins 200 are exposed when the first cover 300 and the second cover 400 are folded with respect to the adapter body 100, respectively.

Compared with the conventional art, the power adapter 10 according to the present embodiment is provided, when the first cover 300 and the second cover 400 are closed with respect to the adapter body 100, respectively, the pins 200 are covered, so that the pins 200 can be protected from being damaged and other objects can be prevented from being damaged by the pins 200. When the user uses the power adapter 10, the pins 200 are exposed when the first cover 300 and the second cover 400 are folded with respect to the adapter body 100, respectively, and the user can hold the first cover 300 and the second cover 400 to insert the pins 200 of the power adapter 10 into the sockets 50. The thickness of the adapter body 100 can be made thinner on the premise that the distance between the outer side surface of the first cover 300 and the edge of the pin 200 adjacent to the first cover 300 meets the safety regulations (typically 6.5mm or more), thereby facilitating the miniaturization of the power adapter 10.

Specifically, the adapter body 100 has a first side 120 and a second side 130 disposed opposite to each other. The first cover 300 has a first surface 310 and the second cover 400 has a second surface 410. The first surface 310 is coplanar with the first side 120 when the first cover 300 is closed relative to the adapter body 100; the first surface 310 faces the first side 120 when the first cover 300 is folded against the adapter body 100; the second surface 410 is coplanar with the second side 130 when the second cover 400 is closed with respect to the adapter body 100, and the second surface 410 faces the second side 130 when the second cover 400 is folded with respect to the adapter body 100.

The first surface 310 facing the first side 120, includes: the first surface 310 is directly attached to the first side 120, and also includes a gap between the first surface 310 and the first side 120, and also includes that the first surface 310 is indirectly attached to the first side 120 through a first flexible film. Likewise, the second surface 410 faces the second side 130, including: the second surface 410 is directly attached to the second side 130, and also includes a gap between the second surface 410 and the second side 130, and also includes that the second surface 410 is indirectly attached to the second side 130 through a second flexible film.

Specifically, the power adapter 10 further includes a first component 500 and a second component 600. One end of the first assembly 500 is connected to the first cover 300, and the other end of the first assembly 500 is connected to the adapter body 100, so that the first cover 300 is rotatably connected to the adapter body 100. One end of the second assembly 600 is connected to the second cover 400, and the other end of the second assembly 600 is connected to the adapter body 100, so that the second cover 400 is rotatably connected to the adapter body 100. The first module 500 and the second module 600 may take a variety of forms, which are described in detail below.

The first component 500 is a first flexible membrane and the second component 600 is a second flexible membrane. The first flexible film is attached to the first side 120 and the first surface 310 such that the first cover 300 is rotatably connected to the adapter body 100, and the second flexible film is attached to the second side 130 and the second surface 410 such that the second cover 400 is rotatably connected to the adapter body 100.

The first component 500 and the second component 600 may also take other forms, please refer to the above description, and the description is omitted herein.

In combination with the power adapter 10 provided in any one of the foregoing embodiments, the thickness d1 of the power adapter body 100 in the power adapter 10 ranges from: d1 is less than or equal to 6.3mm and less than or equal to 14mm.

Wherein the width of the pins 200 is typically 6.3mm for a power adapter 100 adapted for use in china due to safety regulations. Therefore, d1 is not less than 6.3mm. In order to make the power adapter 10 lighter and thinner, the thickness d1 of the adapter body 100 is less than or equal to 14mm.

In one embodiment, the thickness d1 of the adapter body 100 ranges from: d1 is more than or equal to 9.65mm and less than or equal to 14mm; the thickness d2 of the first cover 300 ranges from: d2 is more than or equal to 4.825mm and less than or equal to 7mm; the thickness d3 of the second cover 400 ranges from: d3 is more than or equal to 4.825mm and less than or equal to 7mm.

In an embodiment, the thickness d2 of the first cover 300 and the thickness d3 of the second cover 400 are equal, and the sum of the thickness d2 of the first cover 300 and the thickness d3 of the second cover 400 is equal to the thickness d1 of the adapter body 100.

The above-mentioned choice of dimensions is not arbitrary but is designed in connection with the requirements of safety regulations in the power adapter 10. Specifically, when the first cover 300 and the second cover 400 are relatively opened, the side of the pin 200 adjacent to the first cover 300 must be required to be spaced apart from the outermost surface of the first cover 300 by a distance of 6.5mm or more due to safety regulations in order to prevent the power adapter 10 from being electrically leaked to injure a user when the power adapter is inserted into the socket 5 through the pin 200. Likewise, due to safety regulations, the side of the pin 200 adjacent to the second cover 400 must be required to be spaced from the outermost surface of the second cover 400 by a distance of 6.5mm or more. Then, and also due to safety regulations, the width of the pin 200 is 6.3mm, and therefore, the minimum value of the thickness d1 of the adapter body 100, the first cover d2, and the second cover d3 is d1+d2+d3=6.3mm+6.6mm+6.5 mm=19.3 mm. Then, when the sum of the thickness d2 of the first cover 300 and the thickness d3 of the second cover 400 is equal to the thickness d1 of the adapter body 100, the minimum value of the thickness d1 of the adapter body 100 is equal to 19.3 mm/2=9.65 mm. When the thickness of the first cover 300 is equal to the thickness of the second cover 400, d2=d3=9.65 mm/2=4.825 mm. That is, the minimum value of the thickness of the first cover 300 is 4.825mm, and the minimum value of the thickness of the second cover 400 is 4.825mm. Since the thickness of the adapter body of the conventional power adapter is generally greater than 14mm, the upper limit of the adapter body 100 may be selected to be 14mm in order for the adapter body 100 in the power adapter 10 of the present case to be thin. When the thicknesses of the first cover 300 and the second cover 400 are equal, and the sum of the thickness of the first cover 300 plus the thickness of the second cover 400 is equal to the thickness of the adapter body 100, the upper limit of the thickness of the first cover 300 is 7mm, and the upper limit of the thickness of the second cover 300 is 7mm.
