DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0037] like Figure 1 , Figure 2 As shown, this embodiment proposes an external solar charging device for use on a mobile terminal 10, which can be a mobile device such as a laptop computer or a tablet computer. For the convenience of structural description, taking a laptop computer as an example, the long side direction of the laptop computer is the length direction, and the short side direction is the width direction. When the display screen of the laptop computer is opened in a vertical state, the length direction is the left-right direction, and the width direction is the up-down direction. The components in this embodiment are described structurally with reference to the above directions. Specifically as follows:

[0038] like Figure 1 , Figure 2 As shown, the external solar charging device of this embodiment mainly includes: an external shell 100, a photovoltaic charging panel 200 and a connector 300. The specifications of the external shell 100 are matched with the conventional size of the shell of the mobile terminal 10, for example, it is set to be a rectangle, such as Figure 1 , Figure 3 , Figure 4As shown, a housing cavity 110 is formed in the external shell 100, and the back plate of the external shell 100 is used to connect to the outer shell of the mobile terminal 10, and the side opposite to the back plate is open to form a cavity 111 of the housing cavity 110. An electrical connector 120 is provided on one side of the external shell 100, and the electrical connector 120 is exposed from the external shell 100, and is electrically connected to the photovoltaic charging panel 200 in the housing cavity 110. The electrical connector 120 is used for detachable electrical connection with the external mobile terminal 10; the electrical connector 120 can adopt a USB pluggable socket, such as: USB female head, typy-C female head or Lightning interface, etc. When in use, the electrical connector 120 can be connected to the charging port of the mobile terminal 10 through a universal connecting line, and when not in use, the universal connecting line can be unplugged. Make the electrical connection method of this external solar charging device and the mobile terminal 10 more convenient. The photovoltaic charging panel 200 is connected to the outer shell 100 and is in an unfolded state (such as Figure 6 ) and the receiving state in the receiving chamber 110 (such as Figure 1 , Figure 3 ). When the photovoltaic charging panel 200 is flipped from the cavity opening 111 to the outside of the accommodating cavity 110, the photovoltaic charging panel 200 can be unfolded and placed on the desktop. At this time, in the unfolded state, the photovoltaic surface 201 of the photovoltaic charging panel 200 faces upward, and the sunlight shining on the photovoltaic surface 201 can generate solar power. When charging is not needed, the photovoltaic charging panel 200 is flipped into the accommodating cavity 110 to form a storage state. In the storage state, the photovoltaic surface 201 of the photovoltaic charging panel 200 is hidden in the accommodating cavity 110, and the back of the photovoltaic charging panel 200 faces outward to seal the cavity opening 111. The connector 300 is arranged on the surface of the external shell 100 away from the accommodating cavity 110, and the back plate of the external shell 100 is mounted on the outer shell of the mobile terminal 10 through the connector 300. Through the connector 300, the external solar charging device can be used as a charging device alone and connected to the back shell of the mobile terminal 10 through the connector 300. It can be used as an external charging device for the mobile terminal 10 and can be used in conjunction with a variety of mobile terminals 10. It has high flexibility and practicality.

[0039] Therefore, when the external solar charging device is in use, the photovoltaic charging panel 200 is turned over to achieve storage and deployment of the photovoltaic charging panel 200. When the photovoltaic charging panel 200 is in the deployed state, the photovoltaic surface of the photovoltaic charging panel 200 is turned out from the accommodating cavity 110 and deployed to face the sun, so that solar charging can be successfully completed. When the photovoltaic charging panel 200 is in the stored state, solar charging is not performed. The photovoltaic charging panel 200 is turned over so that the photovoltaic surface faces the accommodating cavity 110 for hiding, so that it is stored in the external shell 100, and the back of the photovoltaic charging panel 200 is located on the outside. In this way, the photovoltaic surface of the photovoltaic charging panel 200 is well protected by the accommodating cavity 110 of the external shell 100, so that the photovoltaic surface is not easily damaged, and the service life of the solar charging device is guaranteed.

[0040] The connecting member in this embodiment can adopt a variety of structures, such as a screw connection structure, in which the external shell is detachably connected to the back shell of the mobile terminal 10 by setting a connecting screw; an elastic lock structure can also be adopted, in which the external shell is detachably connected to the back shell of the mobile terminal 10 by setting an elastic buckle; it can also be a magnetic structure, in which the external shell is attached to the back shell of the mobile terminal by magnetic attraction; it can also be fixed by bonding, as follows:

[0041] like Figure 1 , Figure 4 As shown, further, the connector 300 in this embodiment includes an adhesive layer 310, and the adhesive layer 310 is applied to the surface of the external shell 100. The back of the entire external shell 100 is bonded and fixed to the shell of the mobile terminal 10 through the adhesive layer 310. Quick connection can be achieved. The viscosity of the side of the adhesive layer 310 connected to the external shell 100 is greater than the viscosity of the side used to connect to the mobile terminal 10, so that the entire external shell 100 needs to be disassembled after not in use, and the adhesive layer 310 is removed, so that no adhesive is left on the back of the external shell 100.

[0042] The adhesive layer 310 in this embodiment can be a whole square adhesive layer 310, whose shape matches the shape of the back of the external shell 100, and whose length and width are slightly smaller than the length and width of the external shell 100. After bonding, the long side and the wide side of the external shell 100 can be connected to the outer shell surface of the mobile terminal 10.

[0043] like Figure 5 As shown, further, the connector 300 in this embodiment further includes: a release film layer 320, which is arranged on the side of the adhesive layer 310 away from the external shell 100. The release film layer 320 is a plastic film, which covers and protects the adhesive layer 310 before use. When in use, the release film layer 320 is torn off, and then the adhesive layer 310 is adhered to the shell surface of the mobile terminal 10.

[0044] like Figure 4 , Figure 6 , Figure 7 As shown, further, one side of the external shell 100 in this embodiment is hinged with an outer cover plate 400, and the photovoltaic charging panel 200 can be bonded and fixedly connected to the outer cover plate 400, and the photovoltaic charging panel 200 is located outside the accommodating cavity 110 or accommodated in the accommodating cavity 110 by flipping the outer cover plate 400. By fixing the photovoltaic charging panel 200 on the outer cover plate 400, the rigidity and structural strength of the outer cover plate 400 are higher than those of the photovoltaic charging panel 200, so that the photovoltaic charging panel 200 can be supported by the outer cover plate 400, and the flipping of the photovoltaic charging panel 200 can be achieved by flipping the outer cover plate 400, so that the connection between the photovoltaic charging panel 200 and the outer cover plate 400 is more stable. In addition, the outer cover plate 400 is located on the outer surface of the photovoltaic charging panel 200, which can better protect the photovoltaic charging panel 200.

[0045] like Figure 4 , Figure 6 , Figure 7 As shown, further, the outer cover plate 400 in this embodiment includes a metal heat sink 410. The metal heat sink 410 can be an aluminum plate, a stainless steel plate, etc. In this way, the outer cover plate 400 not only plays a role in bearing and protecting the photovoltaic charging panel 200. In addition, when the photovoltaic charging panel 200 performs solar power generation, it can also conduct heat in time, and conduct the heat of the photovoltaic charging panel 200 in time to dissipate heat. Thereby improving the heat dissipation capacity of the photovoltaic charging panel 200, so that the charging efficiency of the photovoltaic charging panel 200 remains stable and efficient. It is easy to imagine that the outer cover plate of this embodiment can also be made of a plastic plate, which has a protective and anti-damage function.

[0046] The outer cover plate 400 in this embodiment can be hinged at one side edge of the outer shell 100, such as the left edge, the right edge or the upper edge, and can be flipped to achieve the technical effect. Figure 4 , Figure 6 , Figure 8 As shown, further, the outer cover plate 400 in this embodiment is connected to the lower edge of the outer shell 100 through a hinge 420. The outer cover plate 400 is hinged to the lower edge of the outer shell 100, so that the photovoltaic charging panel 200 is opened from the upper edge and flipped downward during the unfolding process, so that the photovoltaic surface of the flipped photovoltaic charging panel 200 is just facing upward, making the use of the photovoltaic charging panel 200 more convenient.

[0047] like Figure 4 , Figure 8As shown, further, the hinged member 420 in this embodiment specifically includes: a hinged rod 421 and a hinged platform 422. The hinged rod 421 is arranged on the outer shell 100 along the length direction and penetrates the accommodating cavity 110, and the hinged platform 422 is arranged on the inner wall of the outer cover 400 and is provided with a through hole; the hinged platform 422 is sleeved on the hinged rod 421 through the through hole, so that the outer cover 400 rotates around the hinged rod 421. In the specific structure, a plurality of hinged platforms 422 are arranged at intervals along the length direction, and the through holes of the plurality of hinged platforms 422 are coaxially arranged. The hinged rod 421 passes through the outer shell 100 and sequentially passes through the through holes of the hinged platform 422, so that the hinged platform 422 can rotate around the hinged rod 421.

[0048] like Figure 4 , Figure 6 , Figure 7 As shown, further, in this embodiment, a magnetic attraction component 130 is provided in the accommodating cavity 110, and the outer cover 400 covers the cavity opening 111 of the accommodating cavity 110 through the magnetic attraction component 130. The magnetic attraction component 130 is used to realize the magnetic connection between the outer cover 400 and the external shell 100, so that the user can flip the outer cover 400 to open and close it by suction, which optimizes the structure, is convenient to use, and has strong practicality.

[0049] like Figure 4 , Figure 6 , Figure 7 As shown, further, the magnetic attraction assembly 130 in this embodiment specifically includes: a plurality of magnetic attraction blocks 131 and a magnetic attraction area 132. The plurality of magnetic attraction blocks are arranged along the side edges in the length direction and / or the side edges in the width direction of the external shell.

[0050] In the specific structure, a plurality of magnetic blocks 131 are arranged along both sides of the length direction of the external shell 100, and along one side (upper side) of the width direction of the external shell 100, forming a three-side magnetic structure except for the hinged side. The magnetic area 132 is located on the side of the outer cover 400 facing the accommodating cavity 110, and is arranged corresponding to the magnetic block 131. Figure 8 As shown, if the metal heat sink 410 has magnetic properties, the magnetic area 132 can be the entire metal heat sink 410. Magnetic blocks 131 are set on both sides of the external shell 100, and multiple magnetic blocks 131 on one side are set at intervals along the width direction, so that the suction force is stronger, and the left and right sides of the external shell 100 are adsorbed to make the adsorption more stable. After adsorption, the outer cover 400 is stably connected and not easy to fall off.

[0051] like Figure 4 , Figure 6As shown, further, in this embodiment, in order to facilitate the flipping operation of the outer cover plate 400, a cover opening groove 140 is provided on the edge of the outer shell 100. That is, a groove is provided on the side of the upper edge of the outer shell 100 facing the outer cover plate 400, and the cover opening groove 140 provides a force application position for the flipping of the outer cover plate 400. The cover opening groove 140 can be located in the middle position of the length direction of the outer shell 100. When it is necessary to flip and open the outer cover plate 400 after adsorption, the user can directly put his finger into the cover opening groove 140 to conveniently apply force to the outer cover plate 400, making it more convenient to open the outer cover plate 400.

[0052] like Figure 4 , Figure 6 As shown, further, in this embodiment, a plurality of photovoltaic charging panels 200 are provided, and the plurality of photovoltaic charging panels 200 are connected in sequence and folded or unfolded by flipping at the connection. By adopting the form of a plurality of photovoltaic charging panels 200, they can be unfolded for charging, thereby increasing the area of ​​the photovoltaic surface receiving solar energy and improving the charging efficiency. After charging is completed, the plurality of photovoltaic charging panels 200 are folded and stacked on the outer cover plate 400, and then the stacked plurality of photovoltaic charging panels 200 are flipped through the outer cover plate 400 and accommodated in the accommodating cavity 110, so that a larger charging area can be provided in the limited accommodating cavity 110.

[0053] like Figure 4 , Figure 6 As shown, the plurality of photovoltaic charging panels 200 may be 2, 3 or more. Taking 2 photovoltaic charging panels 200 as an example, the side close to the outer shell 100 is the inner side, and the side away from the outer shell 100 is the outer side. The inner photovoltaic charging panel 200 is fixed on the outer cover 400, and the outer photovoltaic charging panel 200 is flipped inwards when stored and stacked on the inner photovoltaic charging panel 200, and the photovoltaic surfaces of the two are opposite.

[0054] Taking three photovoltaic charging panels as an example, the outermost photovoltaic charging panel is flipped toward the back of the middle photovoltaic charging panel when stored, and the photovoltaic surfaces of the two are set opposite to each other; then the stacked middle photovoltaic charging panel is folded toward the photovoltaic surface of the inner photovoltaic charging panel, and the photovoltaic surfaces of the two are set opposite to each other.

[0055] like Figure 4 , Figure 6As shown, further, the multiple photovoltaic charging panels 200 in this embodiment are connected by a connecting sleeve 210. The connecting sleeve 210 can be a rubber sleeve, so that the multiple photovoltaic charging panels 200 can be connected into a whole, and the cable line is wrapped in the connecting sleeve 210, so as to effectively protect the cable, so that the photovoltaic charging panel 200 is more stable and not easy to be damaged during the flipping process. The connecting sleeve 210 forms a flexible connecting belt at the connection of adjacent photovoltaic charging panels 200. The use of a flexible connecting belt enhances the plastic deformation ability of the photovoltaic charging panel 200 during the folding process, making the flipping process of the photovoltaic charging panel 200 more stable.

[0056] In summary, an external solar charging device of the present application can be used as a charging device alone and connected to the back shell of a mobile terminal 10 through a connector 300. It can be used as an external charging device for a mobile terminal 10 and can be used in conjunction with a variety of mobile terminals 10. It has strong flexibility and high practicality. When the external solar charging device is in use, the photovoltaic charging panel 200 is flipped over so that the photovoltaic surface of the photovoltaic charging panel 200 is flipped out of the accommodating cavity 110 and unfolded to face the sun, so that solar charging can be successfully completed. When solar charging is not performed, the photovoltaic charging panel 200 is flipped over so that the photovoltaic surface is hidden in the accommodating cavity 110, so that it is stored in the external shell 100, and the back of the photovoltaic charging panel 200 is located on the outside. In this way, the photovoltaic surface of the photovoltaic charging panel 200 is well protected by the accommodating cavity 110 of the external shell 100, so that the photovoltaic surface is not easily damaged, and the service life of the solar charging device is guaranteed.
