[0036] like Figure 1 As shown, this utility model discloses a mobile phone case device, including a mobile phone protective case 20 and a thin power supply 10. The mobile phone protective case 20 has a receiving cavity adapted to the shape of the mobile phone, and the thin power supply 10 is installed in the receiving cavity. The mobile phone includes, but is not limited to, smartphones, including but not limited to iOS phones or Android phones.
[0037] In some embodiments, the phone case 20 can be made of PC material. PC material phone cases 20 have good light transmittance, high hardness, drop resistance, thinness, and good strength and toughness. Alternatively, the phone case 20 can be made of TPU material. TPU material has excellent resilience, does not deform, has good low-temperature resistance, is non-toxic and odorless, is environmentally friendly, has good color matching, excellent adhesion, low viscosity, good flexural strength, excellent wear resistance, high gloss, and excellent weather resistance, among other advantages. The phone case 20 can also be made of silicone material. Silicone material has excellent resilience, good low-temperature resistance, a comfortable and smooth touch, is non-toxic and odorless, is top-grade environmentally friendly, and has good color matching; a hardness of 60A to 80A is commonly used. Of course, the phone case 20 can also be made of other materials or composite materials according to actual needs; no specific limitations are made here.
[0038] like Figures 2 to 5 As shown, in some embodiments, the thin power supply 10 can be installed on the back of a mobile phone or inside a mobile phone case 20. The thin power supply 10 can serve as an emergency portable power source.
[0039] The thin power supply 10 may include a substrate 11, a battery 12, and a power board 13. The substrate 11 includes a first surface 11a and a second surface 11b facing away from each other. The first surface 11a of the substrate 11 has a battery groove 111 and a power board groove 112 recessed into its second surface 11b. The battery groove 111 and the power board groove 112 are arranged at intervals (or adjacent to each other) in the horizontal direction. The battery 12 is installed in the battery groove 111, and the power board 13 is disposed in the power board groove 112, and the battery 12 and the power board 13 are interconnected. The power board 13 is provided with a charging terminal 131, the thickness of which is approximately 0.7 mm. Preferably, the charging terminal 131 includes a Type-C charging terminal, which enables fast charging.
[0040] The substrate 11 is also provided with a terminal groove 113 that runs through its first surface 11a and second surface 11b. The terminal groove 113 is connected to the battery slot 111. The charging terminal 131 is located in the terminal groove 113. Since the battery 12 is located in the battery slot 111 and the power board 13 is located in the power board slot 112, the overall thickness of the thin power supply is small and the structure is compact, which effectively improves the portability of the thin power supply 10. In addition, since no charging terminal block or other structures are provided, the overall thickness of the charging structure is small, making the structure of the entire thin power supply 10 more compact. This allows the thin power supply 10 to be installed in the mobile phone protective case 20 for use together, improving the practicality of the thin power supply 10.
[0041] In some embodiments, the mobile phone case 20 has a camera hole 21, and the shape of the substrate 11 is the same as or similar to the structural shape of the mobile phone case 20 excluding the camera hole 21. Further, the substrate 11 has a power board slot 112 on one side (e.g., the right side) of the camera hole 21, and a power board 13 is disposed within the power board slot 112. A battery slot 111 may be provided on the substrate 11 below the camera hole 21; this area has a large flat surface area suitable for battery 12 installation. Preferably, the battery 12 can be a rectangular flat structure, and the battery slot 111 is also approximately a rectangular slot structure.
[0042] like Figure 6 As shown, in some embodiments, the inner sidewall of the power board slot 112 is also provided with a support step 1121. The support step 1121 defines the power board slot 112 into a first accommodating space 112a and a second accommodating space 112b. The second accommodating space 112b is disposed near the second surface 11b of the substrate 11.
[0043] The power board 13 has an upper surface 13a and a lower surface 13b facing away from each other. Electronic components 132 are provided on both the upper surface 13a and the lower surface 13b. The periphery of the lower surface 13b of the power board 13 abuts against the supporting step 1121. The electronic components 132 on the lower surface 13b of the power board 13 are located in the second receiving space 112b, resulting in a smaller overall thickness of the thin power supply 10 after the power board 13 is mounted on the substrate 11. Furthermore, the electronic components 132 on the upper surface 13a of the power board 13 do not protrude from the first surface 11a of the substrate 11, resulting in a relatively flat surface structure for the thin power supply 10. The electronic components 132 include resistors, light sources, processors, and other components.
[0044] In some embodiments, the thin power supply 10 further includes a cover 14, which is bonded to the first surface 11a of the substrate 11. The cover 14 can protect the battery 12 and the power board 13. Of course, in some embodiments, the cover 14 may not be provided, and the thin power supply 10 can be directly assembled into the receiving cavity of the mobile phone protective case 20, which protects the battery 12 and the power board 13 and showcases the beauty of the electronic structure.
[0045] In some embodiments, the shape of the cover plate 14 is similar to the shape of the substrate 11; in other embodiments, such as... Figure 7 and Figure 8As shown, the shape of the cover 14 is the same as or similar to the shape of the phone case 20. Specifically, the shape of the cover 14 is the same as or similar to the shape of the back structure of the phone case 20, and the cover 14 may be provided with a mounting hole. The mounting hole is the same as or similar in shape to the camera hole 21 of the phone case 20. Preferably, the size of the mounting hole may be slightly larger than the size of the camera hole 21. Of course, the structural shape of the cover 14 can also be selected and set according to actual needs, and no specific limitation is made here.
[0046] In some embodiments, the cover 14 may be made of PVC or PC material, or other insulating materials. Alternatively, the cover 14 may be made of other light-transmitting materials. Furthermore, the cover 14 may be manufactured by stamping or CNC machining, and its thickness is approximately 0.1 mm to 0.4 mm, preferably 0.3 mm.
[0047] Furthermore, the cover plate 14 can be decorated with various patterns, which can serve a certain decorative purpose. These patterns can include, but are not limited to, plant patterns, animal patterns, text patterns, or cartoon patterns. Plant patterns can include, but are not limited to, lotus patterns, chrysanthemum patterns, grass patterns, and / or small tree patterns. Animal patterns can include, but are not limited to, the twelve Chinese zodiac animals. Text patterns can include, but are not limited to, patterns of poems or auspicious sayings, such as "Good things happen" or "Good fortune abounds." Cartoon patterns can include, but are not limited to, original cartoon characters. The patterns can be formed on the cover plate 14 through printing or engraving.
[0048] In some embodiments, the cover 14 is connected to the first surface 11a of the substrate 11 by adhesive bonding, snap-fit bonding, and / or magnetic attraction. For example, the cover 14 is connected to the first surface 11a of the substrate 11 by adhesive bonding, and the periphery of the surface of the cover 14 that is in contact with the first surface 11a of the substrate 11 is provided with adhesive (such as 3M adhesive), so that the cover 14 can adhere to the first surface 11a of the substrate 11. In addition, the adhesive can be continuously provided or in multiple intervals, which is not specifically limited here.
[0049] In some embodiments, the cover plate 14 and the substrate 11 are connected by a snap-fit connection. For example, the cover plate 14 has several snap-fits on its surface facing the substrate 11, and the substrate 11 has several slots, allowing them to be snap-fit connected. Since the thickness of the substrate 11 is slightly greater than the thickness of the cover plate 14, providing slots on the substrate 11 ensures that the thickness of the cover plate 14 and the substrate 11 does not increase after they are assembled together.
[0050] In some embodiments, the thin power supply 10 further includes a wireless charging coil connected to the power board 13, the wireless charging coil being disposed within the battery compartment 111.
[0051] In some embodiments, the phone case 20 may also be provided with a first magnetic member 22, and the thin power supply 10 may also be provided with a second magnetic member that cooperates with the first magnetic member 22. The second magnetic member may be disposed in the battery compartment 111. Of course, the second magnetic member can also be used to magnetically attract the phone, so that the thin power supply 10 can be magnetically attracted to the back of the phone. Of course, a third magnetic member may also be provided on the cover 14 (in conjunction with...). Figure 8 As shown in the figure, no specific limitations are made here.
[0052] In some embodiments, the power board 13 includes a flexible power board 13.
[0053] In some embodiments, the second surface 11b of the substrate 11 is planar, so that when the thin power supply 10 is assembled inside the mobile phone protective case 20 or on the back of the mobile phone, the second surface 11b of the substrate 11 can fit against the back of the mobile phone without abrading the back of the mobile phone.
[0054] In some embodiments, the width of the terminal slot 113 is smaller than the width of the power board slot 112, so that the power board slot 112 can limit the power board 13. Preferably, the power board 13 can be fixed in the power board slot 112 by adhesive bonding, or the power board 13 can be installed in the power board slot 112 by fasteners such as bolts or screws. Of course, the power board 13 can also be snapped into the power board slot 112. The installation method of the power board 13 can be selected and set according to actual needs, and no specific limitation is made here.
[0055] In some embodiments, the battery 12 may be fixed in the battery compartment 111 by adhesive bonding, for example, the battery 12 may be fixed in the battery compartment 111 by adhesive (such as 3M adhesive), and no specific limitation is made here.
[0056] In some embodiments, the battery 12 can provide power to or draw power from a mobile phone. Preferably, the battery 12 has a length of 99mm, a width of 64mm, and a thickness of 2.5mm. Of course, other specifications can be selected for the battery 12 according to actual needs, and no specific limitation is made here. Preferably, the battery 12 includes a lithium-ion battery.
[0057] In some embodiments, the power board 13 may be equipped with a light source, which can be used to display the charging type, charging status, or power status. That is, the light source can serve as an indicator light. The charging type may include wireless charging or charging terminal charging. The charging status may include at least one of charging, fully charged, and charging required. The power status may include 0-25% power, 25%-50% power, 50%-75% power, 75%-100% power, etc. For example, red light may flash when the power is 0-25%, green light may flash when the power is 100%, white light may be displayed when wireless charging is used, and blue light may be displayed when charging terminal is used.
[0058] Of course, in some embodiments, when the battery 12 is low in power, it flashes red light or remains red; when it is charging, it flashes blue light or remains blue; and when the battery 12 is fully charged, it flashes green light or remains green. Understandably, the light source can be selected according to actual needs, and no specific limitation is made here.
[0059] The light source can be, but is not limited to, an LED light source, which can include RGBW LED chips. The LED light source can be a surface-mount LED.
[0060] In some embodiments, the power board 13 may be equipped with a processor, and the processor 211 may be an IP5561 chip.
[0061] In some embodiments, the substrate 11 may be an FR-4 board.
[0062] In some embodiments, the side wall of the phone case 20 of the phone case device opposite to the charging terminal 131 of the thin power supply 10 is provided with a through hole so as to facilitate connection with the charging terminal 131 through a charging cable for charging and discharging.
