The mobile power supply 200 can be attached to and fixedly connected with the rear cover, so that the mobile power supply 200 can conveniently charge the terminal device 100 and improve the portability of the mobile power supply 200. Further, in some embodiments, the mobile power supply 200 can also be detachable from the terminal device 100. In other embodiments, the terminal device 100 may be a tablet computer or a palm computer.
Referring to fig. 2, the mobile power supply 200 includes a body 210 and an adhesive 220, and the body 210 has a substantially rectangular block shape and includes a battery for charging the terminal device 100. Further, the body 210 may include a casing surrounding the battery, and the casing may protect the battery. Of course, the housing is not required, for example the housing may be part of a battery. The back adhesive 220 is connected to the surface of the body 210, the material of the back adhesive 220 may be rubber or silica gel, and the back adhesive 220 has viscosity, so that the body 210 can be attached to the terminal device 100 to fixedly connect the body 210 to the terminal device 100. For example, in the embodiment where the terminal device 100 is a smart phone, the back adhesive 220 made of the above material can be reliably attached to the rear cover, so that the mobile power source 200 and the terminal device 100 can be reliably fixed, and further, the mobile power source 200 can conveniently charge the terminal device 100 and improve the portability of the mobile power source 200. The gum 220 made of the above materials is also beneficial to residue-free separation of the mobile power supply 200 and the rear cover, so that the universality of the mobile power supply 200 is improved, and the replacement of the mobile power supply 200 is facilitated, and the gum 220 can be convenient for a user to conveniently detach the mobile power supply 200 from the terminal device 100 or install the mobile power supply 200 in the terminal device 100 according to a use scene.
Further, in some embodiments, the thickness d of the adhesive backed 220 is not greater than 1 mm, e.g., the thickness d of the adhesive backed 220 may be 0.9 mm, or 0.8 mm, or 0.7 mm, or 0.6 mm, or 0.5 mm, etc. The back adhesive 220 with the thickness can ensure the reliable fixation of the mobile power supply 200 and the terminal device 100. Further, in some embodiments, the thickness D of the mobile power supply 200 is no greater than 300 millimeters. For example, the thickness D of the mobile power source 200 may be 290 mm, or 280 mm, or 270 mm, or 265 mm, etc. The mobile power supply 200 with the thickness is convenient for a user to carry, and after the mobile power supply is fixedly connected to the terminal device 100, the thickness of the electronic device 10 is not too large to affect the use of the user. For example, with the smartphone-type terminal device 100, the thickness of the mobile power supply 200 described above does not have a large influence on the user's grip.
Further, in the present embodiment, the volumetric energy density of the battery is not less than 800Wh/L, so that the mobile power supply 200 can have a relatively large battery capacity and a relatively thin thickness. For example, the volumetric energy density of the cell may be 850Wh/L, or 900Wh/L, or 950Wh/L, or 1000Wh/L, etc. Specifically, in some embodiments, the battery is a silicon-containing negative electrode lithium ion battery, or a fuel cell, or a lithium sulfur battery, or a lithium air battery, and when the battery is applied to the mobile power source 200, the mobile power source 200 may have a relatively large battery capacity at a relatively thin thickness. Further, in some embodiments, the battery includes a lithium metal negative electrode, a liquid electrolyte, a separator, and a ternary lithium positive electrode, and when the battery is applied to the mobile power supply 200, the mobile power supply 200 may have a relatively large battery capacity at a relatively thin thickness. In some embodiments, the battery includes a lithium metal negative electrode, a liquid electrolyte, a separator, and a lithium cobaltate positive electrode, and when the battery is applied to the mobile power source 200, the mobile power source 200 may have a relatively large battery capacity at a relatively thin thickness. In some embodiments, when the battery includes a lithium metal negative electrode, a solid state electrolyte, and a ternary lithium positive electrode, or the battery includes a lithium metal negative electrode, a solid state electrolyte, and a lithium cobaltate positive electrode, such a battery is applied to the mobile power source 200, the mobile power source 200 may have a relatively large battery capacity at a relatively thin thickness. In other embodiments, the negative electrode of the battery may be made of a copper foil that does not contain lithium metal, so that the battery has a relatively thin thickness and is capable of having a relatively high volumetric energy density.
Further, in some embodiments, in conjunction with fig. 1, the size of the cross section of the mobile power source 200 is similar to the size of the terminal device 100, that is, the length size of the mobile power source 200 matches the length size of the terminal device 100, and the width size of the mobile power source 200 matches the width size of the terminal device 100. After the mobile power supply 200 is attached to the terminal device 100 and fixedly connected to the terminal device 100, the circumferential outer surface of the mobile power supply 200 may be flush with the circumferential outer surface of the terminal device 100 to form a more integrated appearance, and is convenient for a user to hold. Of course, in other embodiments, the size of the cross section of the mobile power supply 200 may be smaller than the size of the terminal device 100, so as to facilitate fixing the mobile power supply 200 on the back of the terminal device 100 and facilitating the holding of the user. In other embodiments, the body 210 may have other shapes, such as a circular shape, a rounded rectangle, or a racetrack shape, where the rounded rectangle refers to a circle arc transition at four corners of the rectangle, and the racetrack shape refers to a figure formed by two short sides of the rectangle circumscribing a semicircle.
Referring to fig. 2, in some embodiments, the body 210 includes a coil module 230, the coil module 230 is electrically connected to the battery, the coil module 230 and the back adhesive 220 are located on the same side of the body 210, and the coil module 230 can be used for wirelessly charging the terminal device 100. Of course, in this embodiment, the terminal device 100 is provided with a charging coil matching with the coil module 230, and the energy of the battery can be transferred to the terminal device 100 by using the electromagnetic induction between the coil module 230 of the mobile power supply 200 and the charging coil of the terminal device 100, so as to conveniently charge the terminal device 100 by using the mobile power supply 200. Further, in the embodiment that the body 210 is rectangular block-shaped, the coil module 230 may be located at a side of a rectangular surface of the rectangular block with a larger area, and the coil module 230 may be located at a central area of the rectangular surface, so that when the mobile power supply 200 is fixedly connected to the terminal device 100, the central axis of the mobile power supply 200 and the central axis of the terminal device 100 may be overlapped or have a smaller offset distance, so as to improve the appearance characteristic of the electronic device 10 and facilitate the holding of a user. Of course, in other embodiments, the position of the coil module 230 may be adaptively adjusted according to the position of the charging coil of the terminal device 100. Further, in some embodiments, the back adhesive 220 covers the coil module 230 to protect the coil module 230. Referring to fig. 3, in other embodiments, the coil module 230 is exposed to the side of the back adhesive 220, and the coil module 230 may include a protective material covering the coil, so that the exposed coil module 230 can be effectively protected. Since the coil module 230 is exposed to the side of the back adhesive 220, after the mobile power supply 200 is attached to the back side of the terminal device 100 through the back adhesive 220, the interval between the coil module 230 and the charging coil of the terminal device 100 may be smaller, so that the energy loss in the wireless charging process may be reduced.
Further, in some embodiments, the body 210 includes first and second opposing sides 210a and 210b, at least a portion of the first side 210a being covered by the adhesive 220. For example, in the embodiment that the body 210 has a rectangular block shape, the first side surface 210a is a surface with a larger area of the rectangular block, and the surface may be entirely covered by the adhesive 220 so that the mobile power source 200 can form a reliable fixation with the terminal device 100 when the mobile power source 200 is attached to the terminal device 100. Further, in this embodiment, the back adhesive 220 may form a groove-shaped structure on a side away from the body 210, so as to utilize the groove to accommodate a part of the structure of the terminal device 100, and further enable the mobile power source 200 to better adhere to the back side of the terminal device 100, so that the electronic device 10 has a relatively small thickness as a whole, and the appearance characteristics of the electronic device 10 are improved.
Of course, the first side 210a may be provided with the adhesive 220 only at a local position, for example, the adhesive 220 may be provided at four corners and a central area of the first side 210a, and the adhesive 220 is not required in other areas. The arrangement mode of the gum 220 is beneficial to detaching the mobile power supply 200 from the terminal device 100 while ensuring that the mobile power supply 200 can be reliably connected with the terminal device 100, so that the use convenience of the mobile power supply 200 can be improved. In this embodiment, a groove-shaped structure can be formed by using the back adhesive 220 at a plurality of local positions, so that the mobile power source 200 can be better attached to the back side of the terminal device 100, the electronic device 10 has a relatively small thickness as a whole, and the appearance characteristics of the electronic device 10 are improved.
Further, the body 210 may include another coil module disposed at the second side 210b and electrically connected to the battery, and the second coil module 230 is used for charging the battery. In other words, the mobile power source 200 can be charged by using another coil module, so as to improve the convenience of charging the mobile power source 200. Of course, referring to fig. 4, the mobile power supply 200 may include a connection line 240, the connection line 240 is electrically connected to the battery, and the connection line 240 can be plugged into the terminal device 100 and charge the terminal device 100. Further, the connection line 240 may be easily installed in the body 210 or detached from the body 210, for example, the body 210 is provided with a corresponding interface, and the connection line 240 may be connected to the interface in a pluggable manner. In this embodiment, the terminal device 100 does not need to have a charging coil, and the connection line 240 of the portable power source 200 is inserted into the charging interface of the terminal device 100, so that the portable power source 200 can be used to charge the terminal device 100, thereby increasing the application range of the portable power source 200. In other embodiments, another coil module may be absent, and the connection line 240 can also be used for charging the mobile power supply 200, so as to improve the convenience of charging the mobile power supply 200.
Above-mentioned portable power source 200, because body 210 is equipped with gum 220, and can be with body 210 fixed connection to terminal equipment 100 through gum 220, the battery of body 210 can be more conveniently for terminal equipment 100 charges, body 210 and terminal equipment 100 pass through gum 220 fixed connection back, and the user can carry portable power source 200 more conveniently, and portable power source 200 possesses better portable performance promptly.
