Example
[0044] Referring to Figures 1-8, a smartphone optical storage and charging protective case is disclosed. This protective case is an integrated optical storage and charging case with a unique design and practical functions. It includes a case body 1, which is designed to fully consider the phone's usage and protection needs. The case body 1 features a hollowed-out lens frame 2, precisely corresponding to the phone's camera lens position. This not only effectively protects the lens from scratches and impacts but also perfectly showcases the phone's camera lens, ensuring uninterrupted shooting. The side wall of the case body 1 has buttons corresponding to the phone's volume and power buttons, enhancing the ease of use.
[0045] The back of the phone case body 1 is equipped with a flexible photovoltaic power generation film 3. This flexible photovoltaic power generation film 3 uses perovskite solar power generation film. Compared with traditional solar films, its biggest advantage is that it has lower requirements for lighting conditions. Even in low light conditions indoors, it can generate electricity through a special photoelectric conversion mechanism. For example, under ordinary indoor lighting conditions, it can convert light energy into electrical energy, providing an energy source for subsequent energy storage and power supply.
[0046] The phone case body 1 contains a voltage storage module, which is electrically connected to the flexible photovoltaic thin film 3 and is specifically used to store the electricity generated by the flexible photovoltaic thin film 3. The voltage storage module is connected to the PCB board inside the phone case body 1 through a stable circuit connection. The PCB board, as the control core of the entire protective case, is responsible for coordinating the operation of various components.
[0047] The phone case body 1 includes an outer frame 11. A charging interface 12, electrically connected to a PCB board, is located at the lower end of the outer frame 11. This interface can be used to connect an external charging cable to directly charge electronic devices inside the case. A base 13 is detachably mounted on the outer frame 11 above the charging interface 12. A converter assembly 14 is mounted on the base 13. This converter assembly 14 has a male connector 141 facing the inner area of the outer frame 11 for electrical connection with the phone. The inner area of the outer frame 11 is referred to as the inner frame. In equivalent embodiments, the charging interface 12 can be a common Type-C interface or other general-purpose charging interface types, as long as it can meet the function of external power input. The connection method between the male connector 141 of the converter assembly 14 and the phone, besides the existing design, can also adopt other equivalent connection methods such as magnetic connection, as long as a stable electrical connection is guaranteed. A spring-loaded pogo pin is also provided on the PCB board for electrical connection with the converter assembly 14.
[0048] A switch button 4 is located on one side of the lens frame 2. Switch button 4 is electrically connected to the PCB board and is used to control the on / off discharge of the voltage storage module to the electronic device. When the user's phone battery is low while out and about, simply pressing switch button 4 will transfer the stored power in the voltage storage module to the phone via the PCB board, charging the phone. The power source for the voltage storage module primarily relies on the power generated and stored by the flexible photovoltaic film 3 in everyday use scenarios, greatly enhancing the phone's battery life. Whether under outdoor sunlight or indoor lighting, as long as there is sufficient light, the flexible photovoltaic film 3 can continuously operate, ensuring the phone's battery life and meeting the user's power needs anytime, anywhere.
[0049] In this embodiment, the outer frame 11 and the base 13 are connected by a snap-fit mechanism, supplemented by a unique limiting structure. The outer frame 11 has outer frame grooves 111 on both sides, and the base 13 is equipped with corresponding bosses 131 that can be inserted into the outer frame grooves 111. Within the outer frame grooves 111, protrusions 112 divide them into two connected chambers. When the base 13 is installed, the bosses 131 first enter the chamber closest to the base 13, and then, by pushing, pass the protrusions 112 and insert into the chamber furthest from the base 13. The space of this chamber perfectly matches the bosses 131, thus achieving stable limiting. In an equivalent embodiment, the protrusions 112 can be replaced with elastic blocks, or the positions of the outer frame grooves 111 and the bosses 131 can be interchanged, achieving the same stable connection and limiting effect. Of course, in addition to the stepped distribution shown in Figure 3, the side plates surrounding the outer frame grooves 111 can also adopt an integral structure as shown in Figure 9, with no limitation on the length and width of the side plates.
[0050] To further improve the stability of the base 13 mounted on the outer frame 11, a slot 113 is provided at the lower end of the outer frame 11. There are two slots 113, symmetrically distributed on both sides of the charging port 12. Simultaneously, a corresponding locking block 132 is provided on the base 13.
[0051] In this embodiment, both the slot 113 and the locking block 132 have a "U"-shaped structure. During installation, the locking block 132 of the base 13 is aligned with the slot 113 of the outer frame 11, so that the base 13 moves along the direction of the slot 113. Pressing the base 13 firmly allows the boss 131 to pass over the protrusion 112, achieving the locking effect of the base 13. At the same time, the "U"-shaped structure increases the contact area, effectively preventing the locking block 132 from shaking within the slot 113.
[0052] In this embodiment, spring pins are arranged in an orderly manner in a slot on one side, playing a crucial role in electrical conduction (for this purpose, the bottom wall of the slot is provided with through holes to facilitate the passage of circuits or other components, achieving internal and external functional communication. The number of through holes is between 2 and 8 to meet the needs of different circuit layouts; the number of through holes in the attached figure of this embodiment is three). The base 13 is provided with a rotating plate slot 135, specifically for placing the rotating plate assembly 14. One end of the rotating plate slot 135 extends precisely to the locking block corresponding to the spring pin, forming a clever docking structure. The rotating plate assembly 14 is equipped with a port for electrical connection with the spring pins. When the base 13 is installed on the outer frame 11, the spring pins are compressed and deformed, making close contact with the port of the rotating plate assembly 14, achieving a stable electrical connection between the rotating plate assembly 14 and the PCB board. In equivalent embodiments, conductive spring sheets can be used instead of spring pins, or the shape of the rotating plate slot 135 and the locking block can be changed, such as using an L-shape or a T-shape, to meet different assembly requirements. Through the above structural design, the base 13 is fully utilized, which not only enables quick disassembly and assembly of the protective shell, but also ensures the stability of the circuit connection.
[0053] In this embodiment, the outer frame 11 around the card slot 113 is also provided with a weight-reducing groove, which reduces the weight of the phone case without affecting the structural strength. In an equivalent embodiment, the weight-reducing groove can adopt a hollowed-out mesh design, which can also achieve the purpose of weight reduction and increase the heat dissipation area of the phone case. Of course, if the outer frame 11 does not use a weight-reducing groove, it will not affect the normal use of the phone case.
[0054] In this embodiment, a magnet for auxiliary assembly is provided between the outer frame 11 and the base 13, and a special magnet placement slot is provided on the base 13 for placing the magnet. During installation, the magnetic force generated by the magnet can guide the base 13 to quickly align with the outer frame 11, reducing the difficulty of installation. In an equivalent embodiment, iron plates can also be embedded at corresponding positions on the base and the outer frame, and external magnetic tools can be used to assist in assembly.
[0055] This embodiment optimizes and improves the earpiece position. Two sound transmission holes 133 are provided at the lower end of the outer frame 11, corresponding to the number of mobile phones. The front of the base 13 has an earpiece structure communicating with the sound transmission holes 133. In this structure, the earpiece slot aligns with the sound transmission hole 133, and a step is provided at the upper end of the earpiece slot, on which a mesh fabric 134 is securely fixed. The sound played by the mobile phone enters the earpiece slot through the sound transmission hole 133 and is emitted from the mesh fabric 134. The mesh fabric 134 effectively blocks dust and other foreign objects from entering without affecting sound transmission. Furthermore, the upward-facing earpiece position conforms to people's daily usage habits, resulting in clearer sound reception during calls. In equivalent embodiments, the sound transmission hole 133 can be designed in different shapes, such as circular or square; the mesh fabric 134 can also be replaced with a metal filter, achieving the same dustproof sound transmission effect.
[0056] To improve the stability of the phone placed inside the protective case, silicone pads 5 are provided on the inner sidewall of the phone case body 1. Specifically, they are distributed at the corners of the outer frame 11 and the base 13. When the phone is placed inside the protective case, the silicone pads 5 fill the gap between the phone and the protective case. Their soft texture can cushion external impacts and prevent damage to the phone's corners. Alternatively, rubber pads can be used, or an elastic protrusion structure can be designed inside the phone case to further enhance the stability of the phone. Of course, the normal use of the phone case components is not affected even if silicone pads 5 are not used on the phone case body 1.
[0057] This utility model uses a detachable snap-fit connection between the base 13 and the outer frame 11. With the aid of auxiliary magnets, during installation, the user simply aligns the base 13 with the outer frame 11; the magnetic force of the magnets guides quick positioning, and a gentle press secures the snap-fit, greatly improving the ease of installation. The charging interface 12 and the adapter assembly 14 work together. When an external charging cable is connected to the charging interface 12, it can directly charge the electronic device inside the protective case. The adapter assembly 14 connects to a mobile phone and, controlled by the PCB board, enables photovoltaic charging. In equivalent implementations, the charging interface 12 can use different standard interfaces, and the male connector 141 can be adapted to Apple or Android phones. The earpiece is positioned upwards, resulting in a more direct sound propagation path and clearer call quality, conforming to daily usage habits. The switch button 4 is connected to the PCB board. When needed, pressing the switch allows the stored power in the voltage storage module to charge the electronic device, enhancing battery life and meeting the user's power needs when out and about.
