However, the current outer shells of power adapters are mostly multi-faceted three-dimensional structures, and the light-transmitting holes required for the indicator lights are often opened on one of the planes of the outer shell. However, the light of such light-transmitting holes can only be emitted on one side of the plane where they are provided, making it difficult for them to be seen by users from other angles. That is to say, only when the user faces the plane where the light-transmitting hole is located can the user pay attention to the display state of the indicator light inside. In this way, it undoubtedly greatly limits the observation range of the indicator light.

Specific embodiments

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0031] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more, unless otherwise specifically defined.

[0032] A power adapter is generally a power supply conversion device for electronic devices or electrical appliances, generally composed of components such as a housing, a transformer, an inductor, a capacitor, a control chip, a PCB board, and a display lamp (indicator lamp). The power adapter can also be called a charger, a power supply, etc. The power adapter usually converts AC input power into DC output power and is widely used in electronic devices such as security cameras, set-top boxes, routers, light strips, and massagers. As an important part of electronic devices, the design of the power adapter indeed needs to take into account both functionality and user experience. Currently, power adapters are widely used in various electronic products to provide stable and reliable power support, and the display lamp, as an important indicator of the working state of the power adapter, also needs to be continuously optimized in design.

[0033] A display lamp is usually provided inside the power adapter, and the display lamp can be used to display working states such as the power-on state and the charging state of the power adapter. However, the current housing of the power adapter is mostly a multi-faceted three-dimensional structure, and the light-transmitting holes required for the display lamp are often opened on one of the planes of the housing. However, the light from such light-transmitting holes can only be emitted on one side of the plane where it is provided, making it difficult for users to see it from other angles. That is to say, the propagation direction of the light is strictly limited within the range of this plane. When the user is not on one side of this plane, it is very difficult to observe the state of the display lamp. Especially in different usage scenarios, the user needs to continuously adjust their position to view the state of the display lamp. In this way, it undoubtedly greatly limits the observation range of the display lamp.

[0034] Therefore, this application has made improvements to the relevant power adapter and electronic device based on this.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic structural diagram of the power adapter provided in this embodiment. Figure 2The cross-sectional structural schematic diagram of the power adapter provided by this embodiment. The power adapter of this embodiment includes a housing 100 and a light-emitting component 300. The housing 100 has adjacent first side surface 110 and second side surface 120, and the connection part of the first side surface 110 and the second side surface 120 defines a first edge part 130; wherein, a light-transmitting hole 140 is arranged on the first edge part 130; the light-emitting component 300 is arranged inside the housing 100, and the light-emitting direction of the light-emitting component is arranged towards the light-transmitting hole 140.

[0036] Exemplarily, most power adapters are cuboid structures, and the first side surface 110 and the second side surface 120 are two adjacent surfaces among the six surfaces of the cuboid structure. The first edge part 130 is the intersecting area of the first side surface 110 and the second side surface 120. The light-emitting component 300 is a display lamp or an indicator lamp.

[0037] Currently, the light-transmitting hole 140 of the power adapter is usually directly arranged on one of the side surfaces of the housing 100, and only when the user faces the first side surface 110 can the user observe the light-emitting state of the light-emitting component 300 through the light-transmitting hole 140, and its display range is small. For example, when the power adapter is a cuboid structure and the light-transmitting hole 140 is arranged on the first side surface 110, it is usually very difficult for the first side surface 110 to face the user, resulting in that the user can only observe the light-emitting component 300 by adjusting his own position, which will undoubtedly greatly reduce the signal transmission effect of the light-emitting component 300. However, in this application, by arranging the light-transmitting hole 140 on the first edge part 130 where the first side surface 110 and the second side surface 120 meet, it is beneficial to expand the emission range of the light-transmitting hole 140; specifically, the user may observe the light-emitting component 300 inside the housing along the light-transmitting hole 140 from one side of the first side surface 110, one side of the second side surface 120 or one side of the connection part of the first side surface 110 and the second side surface 120, which is beneficial to expand the display range of the light-emitting component 300.

[0038] In some embodiments of this application, please refer to Figure 3 , Figure 3 shows the partial enlarged structural schematic diagram of A of Figure 2 provided by this embodiment; the power adapter of this embodiment includes a lamp shade 600, and the lamp shade 600 has a light-transmitting part 610 for filling in the light-transmitting hole 140, and the side of the light-transmitting part 610 facing away from the light-emitting component 300 is a curved surface structure.

[0039] It should be explained that the light-transmitting part in this embodiment is a transparent solid structure, similar to a light-transmitting tile. The light-transmitting part is arranged in the light-transmitting hole 140. By setting the side of the light-transmitting part 610 facing away from the light-emitting component 300 as a curved surface structure, the emission angle of the light-emitting component 300 can be expanded, which is beneficial to increasing its visible range.

[0040] In some embodiments of the present application, the side of the light-transmitting portion facing away from the light-emitting element 300 is an arc-shaped structure.

[0041] In some embodiments of the present application, please continue to refer to Figure 2 , the light-transmitting hole 140 of this embodiment has an expanding structure along the first direction a, and the first direction a is the light-emitting direction of the light-emitting element along the light-transmitting hole 140.

[0042] In some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 , the cross-section of the light-transmitting hole 140 of this embodiment on the first plane has an expanding structure along the first direction a; wherein, the first plane is perpendicular to the length direction of the first rib portion 130.

[0043] In some embodiments of the present application, the cross-section of the light-transmitting hole 140 on the second plane is in a crescent shape, and the second plane is perpendicular to the light-emitting direction of the light-transmitting hole 140.

[0044] In some embodiments of the present application, the power adapter further includes a circuit board 400, the circuit board 400 is disposed inside the outer housing 100, and the light-emitting element 300 is disposed at the edge position of the circuit board 400.

[0045] In some embodiments of the present application, please refer to Figure 4 , Figure 4 shows a schematic structural diagram of the power adapter provided in this embodiment. The power adapter of this embodiment further includes a heat dissipation member 500, the heat dissipation member 500 is disposed inside the outer housing 100 and is used to export the heat inside the outer housing 100; wherein, the heat dissipation member 500 has a first portion disposed between the light-emitting element 300 and the light-transmitting hole 140, and a notch 510 is disposed on the first portion, and the notch 510 is disposed in the first direction a, and the first direction a is the light-emitting direction of the light-emitting element along the light-transmitting hole 140.

[0046] It should be noted that the heat dissipation member 500 is generally attached to the power devices inside the power adapter, and the excess heat of the power devices is transferred away by the good heat conduction ability of the heat dissipation member 500 to ensure that the power devices can work in a stable temperature environment. After the heat dissipation member 500 absorbs the heat of the power devices, the heat dissipation surface of the heat dissipation member 500 is used for heat dissipation. However, in traditional power adapters, since the light path between the light-emitting element 300 and the light-transmitting hole 140 cannot be blocked, a notch 510 needs to be provided on the heat dissipation member 500 for the light path of the light-emitting element 300 to pass through.

[0047] It is understandable that the heat dissipation effect of the middle area of ​​the heat sink 500 (the area close to the power device) is better than the heat dissipation effect of the corners of the heat sink 500. And the large plane area of ​​the heat sink 500 can better transfer heat to the outer shell 100 and the external structure than the corner area. However, the existing power adapter usually sets the light-transmitting hole 140 on a certain side of the outer shell 100, resulting in the heat sink 500 also needing to open a notch 510 on the corresponding side, resulting in a reduction in its heat dissipation area. In the embodiment of the present application, by setting the light-transmitting hole 140 on the first edge 130, the notch 510 corresponding to the heat sink 500 is also set at the corresponding position. Since the heat dissipation capacity of the heat sink 500 in the large plane is better than the heat dissipation capacity in the corner of the outer shell 100, compared with the traditional solution, this embodiment can minimize the situation where the heat dissipation capacity of the heat sink 500 is reduced due to the opening of the notch 510.

[0048] In short, in the prior art, since the light-transmitting holes 140 are all set on a certain surface of the power adapter / charger, at the position where the indicator light is set, the heat sink of the power adapter / charger needs to be provided with a notch 510 for light transmission so as to not block the light of the indicator light, thus reducing the heat dissipation area of ​​the heat sink. However, since the indicator light of the power adapter / charger is set at the edge of the circuit board 400, the notch 510 of the heat sink does not need to be so large, which means that the area of ​​the heat sink is increased. Increasing the area of ​​the power adapter / charger heat sink also improves the heat dissipation utilization rate of the whole machine.

[0049] In some embodiments of this application, please continue to refer to Figure 4 The heat sink 500 of this embodiment includes adjacent third and fourth sides, the connection between the third and fourth sides defines a second edge, and the notch 510 is provided on the second edge. It can be understood that the notch 510 is provided on the second edge to maintain the heat dissipation area of ​​the heat sink 500 as much as possible to ensure its heat dissipation effect.

[0050] In some embodiments of this application, please continue to refer to Figure 1 In this embodiment, the first side surface 110 and the second side surface 120 are perpendicular to each other. In other embodiments, the first side surface 110 and the second side surface 120 may also be arranged at other angles.

[0051] In some embodiments of the present application, the light-transmitting hole 140 of the present embodiment is filled with a light-transmitting structure made of a transparent material, so as to ensure that the outer shell 100 has good sealing performance.

[0052] It is understandable that after the light from the light emitting element 300 enters the light-transmitting structure, the light-transmitting structure can also emit light as a secondary light source to expand its observation field of view.

[0053] In some embodiments, please continue to refer to Figure 1 and refer to Figure 5 and Figure 6 , Figure 5 which shows an exploded structural schematic diagram of the power adapter provided in this embodiment; Figure 6 is a structural schematic diagram of the upper housing provided in this embodiment; the outer housing 100 of this embodiment includes an upper housing 160 and a lower housing 150 that are snap-fitted to each other, and the upper housing 160 and the lower housing 150 enclose a receiving cavity. A circuit board 400 is disposed in the receiving cavity, and a display lamp (light-emitting member 300) is disposed on the circuit board 400. A wiring hole is further formed between the upper housing 160 and the lower housing 150 for an external wiring 200 to pass through. The external wiring 200 is an input line or an output line.

[0054] In some embodiments, the external wiring 200 includes a wire clip 210 and an output wire 220. The output wire 220 is used for conducting electricity, and the wire clip 210 is used to fix the output wire 220 on the outer housing 100.

[0055] In some embodiments, an input socket 700 is disposed on a side of the outer housing 100 away from the external wiring 200, and the input socket 700 is used to connect to an input power supply. Wherein, the second side surface 120 is the side surface provided with the wiring hole, so that the light-transmitting hole 140 on the first rib portion 130 is more easily noticed by the user.

[0056] In the embodiments of the present application, please continue to refer to Figure 5 , the power adapter of this embodiment includes an outer housing 100, a light-emitting member 300, and a lamp shade 600. The outer housing 100 has adjacent first side surface 110 and second side surface 120, and the connection between the first side surface 110 and the second side surface 120 defines a first rib portion 130; wherein, a light-transmitting hole 140 is disposed on the first rib portion 130; the lamp shade 600 includes a light-transmitting portion 610 filled in the light-transmitting hole 140; the light-emitting member 300 is disposed in the outer housing 100, and the light-emitting direction of the light-emitting member is set towards the light-transmitting hole 140 and the light-transmitting portion 610.

[0057] Specifically, the outer housing 100 further includes a PCBA board (circuit board 400), an LED lamp bead (light-emitting member 300) is disposed on the PCBA board, and the light-emitting member 300 is disposed at an edge position of the PCBA board and close to the light-transmitting hole 140.

[0058] Specifically, a radiator (heat dissipation component 500) is further included inside the outer housing 100. The radiator includes an upper heat dissipation cover 520 and a lower heat dissipation cover 530. The upper heat dissipation cover 520 is disposed above the PCBA board, and the lower heat dissipation cover 530 is disposed below the PCBA board. The two sides of the upper heat dissipation cover 520 and the lower heat dissipation cover 530 are buckled with each other. The radiator is used to dissipate heat for the PCBA board and the components on the PCBA board. Among them, a notch 510 is provided in the light path from the light-emitting component 300 to the light-transmitting hole 140 of the radiator to avoid the light path.

[0059] More specifically, a mylar sheet 800 is provided between the lower heat dissipation cover 530 and the PCBA board. The mylar sheet 800 is used to isolate the PCBA board and the lower heat dissipation cover 530, playing an insulating role and being able to play a certain role in heat dissipation and heat conduction.
