Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments.

[0024] In the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0025] The power adapter 10 provided in this embodiment can be connected to electronic devices via data cables, such as mobile phones, tablet computers, power banks, etc. Usually, these electronic products will be connected to the power adapter 10 to input stable voltage and current when charging.

[0026] Reference Figure 1The embodiment of the utility model provides a power adapter 10. The power adapter 10 includes, for example, a housing 100, a first heat dissipation cover 210, an electric control component and a second heat dissipation cover 220.

[0027] Specifically, the first heat dissipation cover 210 is connected to the housing 100, and the first heat dissipation cover 210 and the housing 100 together form a receiving chamber 110. The electric control component is arranged in the receiving chamber. The second heat dissipation cover 220 is movably connected to the first heat dissipation cover 210, and the second heat dissipation cover 220 is arranged on a side of the first heat dissipation cover 210 away from the housing 100. The electric control component includes a working state, in which the second heat dissipation cover 220 is opened relative to the first heat dissipation cover 210, so that the first heat dissipation cover 210 and the second heat dissipation cover 220 are exposed to the air.

[0028] Among them, the electric control component may include, for example, components such as a control circuit board, an input circuit board, an output circuit board and a transformer, wherein the control chip on the control circuit board generates heat when working, and the control chip is a heat-generating chip. The input circuit board is electrically connected to the control circuit board, the output circuit board is electrically connected to the control circuit board, and the transformer is electrically connected to the control circuit board to achieve voltage conversion, wherein the transformer and the functional chip generate a lot of heat when working, and are the main heating areas. The electric control component is used to realize the charging function of the power adapter, and the electric control component generates heat when working. The first heat dissipation cover 210 and the second heat dissipation cover 220 are made of, for example, an insulating material with good thermal conductivity, and the thermal conductive structure is made of, for example, polycarbonate resin, graphite, phosphorus-containing flame retardant and other materials, and has the functions of fast thermal conductivity and insulation, which can avoid internal leakage problems, thereby improving the heat dissipation effect while ensuring safety. For example, the electronic control component is arranged in the shell 100, and the second heat dissipation cover 220 is connected to the first heat dissipation cover 210. When the electronic control component is working, since the second heat dissipation cover 220 is opened relative to the first heat dissipation cover 210, the heat generated by the electronic control component is dissipated through the shell 100, the first heat dissipation cover 210 and the second heat dissipation cover 220, thereby increasing the heat dissipation area and achieving a better heat dissipation effect.

[0029] The electric control component also includes a non-working state, in which the second heat dissipation cover 220 is superimposed on the first heat dissipation cover 210, or the second heat dissipation cover 220 covers the first heat dissipation cover 210. When the electric control component is in the working state, in order to increase the heat dissipation area, the user will make the second heat dissipation cover 220 and the first heat dissipation cover 210 in a relatively open state, increase the heat dissipation area, and achieve a better heat dissipation effect; when the electric control component is in the non-working state, the user can apply external force to the second heat dissipation cover 220 as needed to make it overlap or cover the first heat dissipation cover 210, thereby increasing the portability of the power adapter 10 and improving the user experience.

[0030] In one implementation of this embodiment, the second heat dissipation cover 220 is rotatably connected to the first heat dissipation cover 210. For example, referring to Figure 3 The second heat dissipation cover 220 can be rotated relative to the first heat dissipation cover 210 by designing a rotating shaft, a hinge or other rotating connecting parts. Of course, this embodiment is not limited to this.

[0031] In another implementation of this embodiment, refer to Figure 4 , the second heat dissipation cover 220 is slidably connected to the first heat dissipation cover 210. The second heat dissipation cover 220 is slidably connected to the first heat dissipation cover 210, for example, through a sliding structure, so that the second heat dissipation cover 220 can slide relative to the first heat dissipation cover 210. For example, the sliding structure is, for example, a sliding groove and a sliding column. In this embodiment, one or more sliding grooves are provided on the first heat dissipation cover 210, and one or more sliding columns are provided on the second heat dissipation cover 220. The shape and size of the sliding groove are adapted to the sliding column of the second heat dissipation cover 220, so that the second heat dissipation cover 220 can slide along the direction of the sliding groove. The cooperation of the sliding column and the sliding groove can ensure that the second heat dissipation cover 220 is stable during the sliding process and is not easy to separate from the first heat dissipation cover 210, so as to achieve the desired operation effect. In other embodiments, the sliding structure can also be, for example, a structure of a slider and a slide rail, and this embodiment is not limited thereto.

[0032] In this embodiment, the second heat dissipation cover 220 is rotated or slid relative to the first heat dissipation cover 210, so that when the electronic control component is in a working state, the heat dissipation area is increased and the heat dissipation effect is better; when the electronic control component is in a non-working state, the user can rotate or slide the second heat dissipation cover 220 as needed to overlap or cover the first heat dissipation cover 210, thereby increasing the convenience of the power adapter 10 and improving the user experience.

[0033] The power adapter 10 also includes, for example, a heat-conducting portion. The heat-conducting portion is disposed in the accommodating cavity 110, and the heat-conducting portion is connected between the first heat-dissipating cover 210 and the electronic control component. The heat-conducting portion can, for example, be attached to the electronic control component or disposed near the electronic control component, and the heat-conducting portion conducts the heat generated by the electronic control component to the first heat-dissipating cover 210, and the second heat-dissipating cover 220 is connected to the first heat-dissipating cover 210, and the heat is dissipated through the first heat-dissipating cover 210 and the second heat-dissipating cover 220. In this way, by connecting the second heat-dissipating cover 220 to the first heat-dissipating cover 210, the heat-dissipating area is increased, and the heat is dissipated through the first heat-dissipating cover 210 and the second heat-dissipating cover 220, thereby solving the problem of uneven heat conduction and poor heat dissipation effect of the power adapter 10.

[0034] In one implementation of this embodiment, the heat conducting part includes, for example, a heat conductive adhesive filled in the gap between the electronic control component and the first heat dissipation cover 210. The heat conductive adhesive is, for example, filled in the gap between the electronic control component and the first heat dissipation cover 210. In other implementations of this embodiment, the heat conductive adhesive can also be, for example, applied to the electronic control component.

[0035] In another implementation of this embodiment, refer to Figure 3 The heat conducting part is, for example, a heat conducting member 300 disposed between the electronic control component and the first heat dissipation cover 210. The heat conducting member 300 may be, for example, a heat conducting material, such as a structure made of graphene, a heat conducting silicone sheet, or a heat conducting insulating material. Preferably, the heat conducting member 300 may be, for example, made of an insulating material with good heat conducting effect. The heat conducting structure may be made of, for example, polycarbonate resin, graphite, phosphorus-containing flame retardant, etc., which has the effect of fast heat conduction and insulation, can avoid internal leakage problems, thereby improving the heat dissipation effect while ensuring safety.

[0036] Reference Figure 5 , a plurality of protrusions 400 are arranged on the surface of the first heat dissipation cover 210 and the second heat dissipation cover 220, and the plurality of protrusions 400 are arranged at intervals, wherein a through groove 410 is arranged between two adjacent protrusions 400 on the surface of the second heat dissipation cover 220. By providing a plurality of protrusions 400, the surface area of ​​the first heat dissipation cover 210 and the second heat dissipation cover 220 can be effectively increased, so that more heat can contact the surrounding air, thereby accelerating the conduction and dissipation of heat, and further improving the heat dissipation effect of the power adapter 10. In addition, the through grooves 410 on the surface of the second heat dissipation cover 220 correspond to the protrusions 400 on the surface of the first heat dissipation cover 210 one by one, and the protrusions 400 are accommodated in the through grooves 410, for example, in a plug-in manner, so as to enhance the stability when the first heat dissipation cover 210 and the second heat dissipation cover 220 are connected. In other embodiments, a plurality of through grooves are provided on the surface of the first heat dissipation cover body 210 corresponding to the plurality of protrusions 400 of the second heat dissipation cover body 220. The plurality of protrusions 400 are accommodated in the plurality of through grooves 410, for example, in an inserted manner, and cooperate with the through grooves 410 on the surface of the second heat dissipation cover body 220 and the protrusions 400 on the surface of the first heat dissipation cover body 210, so as to further enhance the stability when the first heat dissipation cover body 210 and the second heat dissipation cover body 220 are connected.

[0037] Among them, the plurality of protrusions 400 can be, for example, a heat-conducting material, such as a structural member made of graphene, a heat-conducting silicone sheet, or a heat-conducting insulating material. Preferably, the heat-conducting member 300 can be, for example, a heat-conducting structure, which is made of, for example, polycarbonate resin, graphite, a phosphorus-containing flame retardant, and other materials, and has an insulating effect, which can avoid internal leakage problems, thereby ensuring safety while improving the heat dissipation effect. It should be noted that common phosphorus-containing flame retardants include, for example, organic phosphorus flame retardants, such as tripolyphosphate, hexapolyphosphate, and dodecaphosphate; sulfur-phosphorus flame retardants, such as melamine ammonium phosphate, ammonium phosphate, etc.; stabilizer phosphorus flame retardants, such as tetramethyl ammonium phosphate, etc.; cyclic phosphorus flame retardants, such as phosphorus-nitrogen package compounds, phosphorus-nitrogen resins, etc.; silicon-oxygen phosphorus flame retardants, such as epoxy silane phosphate, etc.

[0038] Reference Figures 1 to 4 A power connection pin 120 is disposed in the housing 100 , and the power connection pin 120 is electrically connected to the electronic control component.

[0039] Specifically, the first heat dissipation cover 210 is provided with a first slot 211 corresponding to the power pin 120, and the power pin 120 passes through the first slot 211 and protrudes from the first slot 211. When the electric control component is in the working state, the second heat dissipation cover is in the open state, and the power pin 120 passes through the first slot 211 to be electrically connected to the external power supply; when the electric control component is in the non-working state, the power pin 120 can be accommodated in the first slot 211, and the second cover can cover the power pin 120 to prevent the power pin 120 from being stained with water or dust, which affects the charging safety.

[0040] Furthermore, the second heat dissipation cover 220 is provided with a second slot 221 corresponding to the power pin 120. When the electric control component is in working state, the power pin 120 passes through the first slot 211 and the second slot 221 in sequence to be electrically connected to the external power supply; when the electric control component is in non-working state, the power pin 120 can be received in the first slot 211.

[0041] In other implementations of this embodiment, the areas on the first heat dissipation cover 210 and the second heat dissipation cover 220 close to the first groove 211 and the second groove 221 can be set as an insulating heat-conducting structure to avoid leakage problems caused by contact with the power pins 120. The areas on the first heat dissipation cover 210 and the second heat dissipation cover 220 away from the first groove 211 and the second groove 221 can be set as metal material components. Metal materials have excellent heat dissipation effects. The above design further improves the heat dissipation effect while ensuring safety.

[0042] Reference Figure 1A pin accommodating portion 130 is provided on the housing 100 , and the power pin 120 is rotatably connected to the housing 100 . The power pin 120 has an open state and a closed state relative to the housing 100 . When the power pin 120 is in the closed state, the power pin 120 is accommodated in the pin accommodating portion 130 .

[0043] Specifically, when the power pin 120 rotates to the closed state, the free end of the power pin 120 is received in the pin receiving portion 130 of the housing 100. The pin receiving portion 130 is, for example, a through slot, etc., for receiving the power pin 120. Preferably, the bottom wall of the pin receiving portion 130 is a plane, an inclined surface, a convex curved surface or a concave curved surface, but the present embodiment is not limited thereto. The pin receiving portion 130 can be provided as an integral part; in other embodiments, the pin receiving portion 130 can also be provided as two independently separated parts, but the present embodiment is not limited thereto.

[0044] Preferably, the first heat dissipation cover 210 and the housing 100 are integrally formed. This connection method is more fixed and stable. Since the first heat dissipation cover 210 and the housing 100 are integrally formed, their connection is more secure, which can provide better stability and support, and avoid the problem of loosening or falling off that may occur during use.

[0045] It can be seen from the above that the above technical features of the utility model can have one or more of the following beneficial effects: by setting the first heat dissipation cover body 210 and the second heat dissipation cover body 220 on the shell 100 of the power adapter 10, the electronic control component arranged in the shell 100 will generate heat when working. Compared with the prior art, the heat dissipation is assisted by setting a heat dissipation material component on the shell connected to the electronic control component, and the heat dissipation area of ​​the heat dissipation structure is relatively small. In this embodiment, the second heat dissipation cover body 220 is connected to the first heat dissipation cover body 210, thereby increasing the heat dissipation area, thereby solving the problem of uneven heat conduction and poor heat dissipation effect of the power adapter 10.

Under the premise that the technical features do not conflict, the structures do not contradict, and the purpose of the present invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.
