[0049] Based on the above mobile terminal hardware structure, various embodiments of the present application are proposed.

[0050] Figure 2 is a schematic view of a middle frame assembly 200 and a protective sleeve 300 according to an embodiment, Figure 3 is a structural schematic view of a conduction assembly 201 according to an embodiment, please refer to Figures 2-3 The embodiment provides a middle frame assembly 200 for a smart terminal, the middle frame assembly 200 includes a middle frame main body 202, a charging circuit and the conduction assembly 201. Optionally, the charging circuit and the conduction assembly 201 are both arranged in the middle frame main body 202, and the conduction assembly 201 is connected to the charging circuit, one end of the conduction assembly 201 at least partially penetrates the middle frame main body 202, and the conduction assembly 201 is used for electrically connecting the charging circuit and an external power supply, so as to charge the smart terminal.

[0051] Optionally, the conduction assembly 201 comprises a middle frame support 203, a conduction spring 204 and a conduction contact 205. The middle frame support 203 is attached to the edge of the middle frame body 202, and a cavity 208 is formed at one end of the middle frame support 203 close to the edge of the middle frame body 202, which is used to accommodate and install the conduction spring 204. The conduction contact 205 is configured to establish electrical connection with the external power supply and the conduction spring 204, and one end of the conduction contact 205 protrudes outside through the middle frame body 202 for contacting the external power supply.

[0052] Optionally, the conduction spring 204 can be a metal spring with elastic deformation capability, one end of which is fixedly installed in the cavity 208 and the other end of which is suspended. The conduction contact 205 is fixedly installed between the cavity 208 and the middle frame support 203, and the metal spring is buckled to close the charging circuit.

[0053] Figure 4 is a structural schematic diagram of the conduction contact 205 according to an embodiment, Figure 5 is a schematic diagram of the internal structure of the middle frame assembly 200 and the protective sleeve 300 according to an embodiment. As Figure 4 shown, in this embodiment, the conduction contact 205 comprises a first connecting end 209 and a second connecting end 210. The first connecting end 209 is arranged on one side of the conduction contact 205 and is used to electrically connect with the conduction spring 204. To ensure the reliability of the contact, the first connecting end 209 can be designed in a square shape, and the flat surface thereof can provide a larger contact area, thereby reducing the contact resistance and improving the stability of the electrical connection. At the same time, the edges of the square structure can better press against the conduction spring 204 to ensure the reliability of the deformation triggering. Figure 5 As

[0054] Optionally, the specific shape of the first connecting end 209 and the second connecting end 210 is not limited to a square or a circle, and those skilled in the art can design other suitable geometric shapes according to actual needs, such as a rectangle, an ellipse or a polygon, to meet different application scenarios and performance requirements. The above shape selection is intended to improve the connection reliability of the conduction contact 205 with the conduction spring 204 and the external power supply, and to optimize the installation and use effect.

[0055] Optionally, the conducting contact 205 is movably arranged between the cavity 208 and the middle frame support 203, and the second connecting end 210 at least partially extends out of the middle frame support 203. When an external force is applied to the second connecting end 210, the first connecting end 209 will exert pressure on the conducting elastic sheet 204, so that the conducting elastic sheet 204 deforms and conducts the circuit, thereby realizing the transmission of electric energy between the external power supply and the charging circuit.

[0056] Optionally, a spring is arranged between the second connecting end 210 and the middle frame body 202. When the charging provided by the external power supply is completed and the pressure applied on the first connecting end 209 disappears, the spring will push the second connecting end 210 back to the initial position through the elastic force of the spring itself, so that the first connecting end 209 is separated from the conducting elastic sheet 204, and the charging circuit is disconnected. The arrangement of the spring not only realizes the automatic reset function of the conducting assembly 201, but also effectively prevents the first connecting end 209 from remaining in contact with the conducting elastic sheet 204 after the external force is removed, thereby avoiding the problems of short circuit or energy loss caused by residual contact.

[0057] Optionally, the material of the conducting contact 205 can be copper, aluminum, stainless steel or gold-plated alloy, etc. The copper material has a low resistivity and excellent processing performance, which is suitable for high-efficiency conduction scenarios; the aluminum material has both electrical conductivity and lightweight characteristics; the gold-plated alloy can provide higher corrosion resistance and contact reliability, and is particularly suitable for application scenarios with high environmental adaptability requirements.

[0058] Figure 6 is a schematic view of the internal structure of the middle frame assembly 200 and the protective sleeve 300 according to the embodiment. As shown in Figure 6 In this embodiment, the conducting assembly 201 further includes a rubber ring 211 arranged between the second connecting end 210 and the middle frame body 202 for waterproofing. The rubber ring 211 is connected to the second connecting end 210 and the middle frame body 202 by interference fit to realize tight sealing and prevent external moisture or humidity from penetrating into the middle frame assembly 200, thereby ensuring the working stability of the conducting assembly 201 and the charging circuit.

[0059] Optionally, the material of the rubber ring 211 can be silicone rubber, fluororubber or nitrile rubber, etc. Silicone rubber has excellent high and low temperature resistance and good elasticity, and is suitable for sealing applications in various environments; fluororubber has excellent chemical resistance and weather resistance, and is suitable for extreme environments; nitrile rubber has good mechanical strength and oil resistance, and is suitable for scenarios that require long-term stable use.

[0060] Optionally, the conducting assembly 201 further comprises a limiting support 207 arranged on the middle frame support 203 for limiting the second connecting end 210. The limiting support 207 is fixedly installed on the top of the middle frame support 203, and is designed to match the shape and size of the second connecting end 210. When the second connecting end 210 passes through the middle frame body 202 and is connected with the external power supply, the limiting support 207 provides mechanical support to prevent the second connecting end 210 from being displaced or falling off due to external force or vibration, thereby ensuring the connection stability of the conducting assembly 201.

[0061] Optionally, the middle frame assembly 200 further comprises at least two first magnets 206 symmetrically arranged on the middle frame support 203, and the N poles of the at least two first magnets 206 are arranged away from the middle frame support 203.

The protective body is used for covering and protecting the smart terminal, and has good impact resistance and wear resistance. The photovoltaic power generation assembly is integrated inside or on the surface of the protective body, and converts light energy into electric energy to provide a clean power source for the smart terminal.

[0066] Optionally, the interface 301 is electrically connected with the photovoltaic power generation assembly for transmitting the generated electric energy to the smart terminal. The interface 301 is configured to be electrically connected with the conducting assembly 201 in the middle frame assembly 200 of the smart terminal, specifically by contacting the interface 301 with the conducting contact 205, so that the photovoltaic power generation assembly and the charging circuit of the smart terminal form a conducting path, thereby charging the smart terminal.

[0067] Optionally, the protective sleeve 300 further comprises at least two second magnets 302 symmetrically arranged on the main body of the protective sleeve 300, the S poles of the at least two second magnets 302 are arranged towards the center of the protective sleeve 300. When the protective sleeve 300 is buckled with the smart terminal, the S poles of the at least two second magnets 302 arranged on the main body of the protective sleeve 300 are attracted to the N poles of the at least two first magnets 206 on the smart terminal middle frame support 203. Through the magnetic force, the protective sleeve 300 is firmly adsorbed to the smart terminal middle frame assembly 200, ensuring that the two are stably attached. Optionally, the symmetric arrangement of the magnets ensures that the protective sleeve 300 and the smart terminal middle frame assembly 200 will not tilt or loosen when affected by external forces, further enhancing the anti-vibration and anti-impact capabilities of the entire structure, providing a more efficient charging experience and more reliable protection for the smart terminal.
