DETAILED DESCRIPTION

[0036] Terminal structural components, including the frame and mid-panel, are crucial components of the overall terminal device structure. These components impact the device's appearance, strength, and weight. Current terminal structural components struggle to balance aesthetics, lightweight design, and cost. This disclosure provides a terminal structural component and terminal device to address related technical issues.

[0037] The present disclosure provides a terminal structural component, which is applied to terminal equipment. Figure 1 and Figure 2 As shown, the terminal structure includes a frame 10 and a mid-plate 20. Frame 10 includes a first frame 11 and a second frame 12 arranged in a stacked manner. First frame 11 faces the exterior of the terminal device, while second frame 12 faces away from the exterior of the terminal device. Mid-plate 20 is electrically connected to second frame 12. First frame 11 and second frame 12 are joined and fixed.

[0038] The frame 10 includes a first frame 11 and a second frame 12 that are stacked. The terminal structure can combine the properties of the first frame 11 and the second frame 12 to achieve the desired appearance and weight. The outward-facing portion of the frame 10 has a significant impact on the appearance and strength of the terminal device. Therefore, the frame 10 is divided into the first frame 11 and the second frame 12. Only the outward-facing first frame 11 uses a high-cost, high-quality material. This can reduce the material consumption when manufacturing the first frame 11 and reduce production costs.

[0039] Specifically, the material of the first frame 11 can be titanium or steel, or precious metals such as gold, silver or platinum, which have high strength and good appearance texture. Only the first frame 11 is made of such high-cost materials, and there is no need for the entire frame 10 to use high-cost materials, thereby reducing the production cost of the terminal structure. Since the second frame 12 is electrically connected to the middle plate 20, so that the frame 10 is used as an antenna, the material of the second frame 12 can be aluminum, which has good conductivity and can reduce weight. The material of the first frame 11 and the second frame 12 is not limited. The material of the middle plate 20 is aluminum alloy, titanium alloy or magnesium alloy to achieve lightweight, and the specific material type is not limited.

[0040] In some embodiments, as Figure 2 As shown, the first frame 11 includes a first fixing surface 111 facing the interior of the terminal device, and the second frame 12 includes a second fixing surface 121 facing the exterior of the terminal. The first fixing surface 111 and the second fixing surface 121 are planar. The first fixing surface 111 and the second fixing surface 121 are connected. The first frame 11 and the second frame 12 are connected by the first fixing surface 111 and the second fixing surface 121, which simplifies the structure and further reduces production costs.

[0041] In other embodiments, Figure 3As shown, the first fixing surface 111 is provided with a fixing groove 113, and the second frame 12 is at least partially embedded in the fixing groove 113. By providing the fixing groove 113 on the first fixing surface 111, the amount of high-performance metal or precious metal used can be reduced to reduce costs.

[0042] The present disclosure also provides a terminal device comprising the aforementioned terminal structural member. Because the terminal structural member combines the properties of the first frame 11 and the second frame 12 to achieve the desired appearance and weight, the terminal device of the present disclosure provides a better user experience. Furthermore, due to the low cost of the terminal structural member, the terminal device of the present disclosure also has a low cost. The terminal device of the present disclosure may be a mobile phone, a tablet computer, an in-vehicle terminal, a medical terminal, a wearable device, or the like, and the present disclosure is not limited thereto.

[0043] like Figure 3 and Figure 4 As shown, the first frame 11 includes an exterior surface 112 facing the outside of the terminal device. Exterior surface 112 can be curved to further enhance the terminal device's appearance and texture. Exterior surface 112 can convex outward from the terminal device, making the entire exterior surface 112 more rounded and improving the user's grip. Exterior surface 112 can also be concave toward the inside of the terminal device, allowing the user's fingers to fit into the concave shape when holding the terminal device, improving grip stability. Exterior surface 112 can also be flat, and the specific structural form is not limited.

[0044] like Figure 3 As shown, the second frame 12 may include a second fixing surface 121 facing the outside of the terminal device and a functional surface 122 facing the inside of the terminal device. Figure 2 As shown, in one embodiment, the fixing groove 113 may be located between the two ends of the first fixing surface 111. Specifically, the fixing groove 113 may be located between the two ends of the first fixing surface 111 in the thickness direction of the terminal device. The second fixing surface 121 may be provided with a fixing protrusion 123, which is assembled with the fixing groove 113.

[0045] Since the fixing groove 113 is located between the two ends of the first fixing surface 111, the fixing protrusion 123 can be clamped between the two ends of the first frame 11, thereby improving the fixing strength of the first frame 11 and the second frame 12, thereby improving the overall strength of the terminal structure.

[0046] In one embodiment, if Figure 4As shown, the fixing groove 113 can extend from one end of the first frame 11 to between the two ends of the first frame 11. On the one hand, because the fixing groove 113 extends through the end surface of the first frame 11, during the manufacturing stage, the grooving tool can simply be inserted into the first frame 11 from one end, reducing the difficulty of machining the fixing groove 113. On the other hand, the second frame 12 can be assembled to the first frame 11 along the extension direction of the fixing groove 113, reducing the difficulty of installing the first and second frames 11, 12 and improving assembly efficiency.

[0047] like Figure 5 and Figure 6 As shown, in one embodiment, the functional surface 122 is provided with a connecting protrusion 124 and a connecting groove 125 to form a first mortise and tenon structure. The middle plate 20 is provided with a second mortise and tenon structure that is assembled with the first mortise and tenon structure. The second mortise and tenon structure also includes a protrusion structure and a groove structure. The protrusion structure of the second mortise and tenon structure is assembled with the groove structure of the first mortise and tenon structure. The groove structure of the second mortise and tenon structure is assembled with the protrusion structure of the second mortise and tenon structure.

[0048] The mortise and tenon structure improves the connection strength between the frame 10 and the middle plate 20. Either the connecting protrusion 124 or the connecting groove 125 can be provided on the functional surface 122. Alternatively, both the connecting protrusion 124 and the connecting groove 125 can be provided on the functional surface 122 to enhance the strength of the mortise and tenon connection. The specific connection method between the first frame 11 and the second frame 12 is not limited.

[0049] like Figure 5 As shown, the number of the connecting protrusion 124 can be one, which is distributed in the middle between the two ends of the functional surface 122. The connecting protrusion 124 can also be located at one end of the functional surface 122. Figure 6 As shown, there may be multiple connecting protrusions 124 , which are spaced apart on the functional surface 122 .

[0050] like Figure 6 and Figure 7 As shown, in an embodiment where the functional surface 122 is provided with multiple connecting protrusions 124, the connecting protrusions 124 may include end protrusions 1241 located at both ends of the functional surface 122 and a middle protrusion 1242 located between the ends of the functional surface 122. The middle protrusion 1242 extends longer than the end protrusions 1241. By providing protrusions of different lengths, the complexity of the mortise and tenon structure can be increased, thereby enhancing the strength of the mortise and tenon joint. The number and distribution of the connecting protrusions 124 are not limited.

[0051] In other embodiments, the connecting protrusions 124 may include only the end protrusions 1241 or only the middle protrusions 1242. That is, there may be two connecting protrusions 124, one at each end of the functional surface 122. A plurality of connecting protrusions 124 may also be spaced apart and distributed between the ends of the functional surface 122.

[0052] In this disclosure, the protrusion and groove structures on the first fixing surface 111, the second fixing surface 121, and the functional surface 122 can be combined in any manner and are not limited to the embodiments provided herein. The frame 10 and the middle plate 20 can also be connected by other methods besides mortise and tenon joints, and the specific connection method between the two is not limited. For example, the frame 10 and the middle plate 20 can be connected by a mechanical connection such as a snap connection, a metallurgical connection such as welding, or an adhesive connection.

[0053] like Figure 1 As shown, the frame 10 may include a plurality of substructures 100 connected to each other. The shape of the substructure 100 may include Figure 8 The U-shaped Figure 9 Type I shown, Figure 10 At least one of the L-shaped frames shown. By separating and then assembling the frame 10, the manufacturing difficulty of the frame 10 is reduced.

[0054] In such Figure 1 In the embodiment shown, the number of substructures 100 can be four, with two U-shaped substructures 100 arranged opposite to each other, and two I-shaped substructures connecting the two U-shaped substructures 100. The number, shape and distribution of the substructures 100 are not limited, as long as they can be connected to form a continuous frame 10 as a whole. The frame 10 can also be made of Figures 11 to 15 Spliced in the manner shown.

[0055] The frame 10 can be formed by bending, forging, 3D printing, or powder metallurgy. The middle plate 20 can be manufactured by CNC (Computerized Numerical Control) machining, rolling, forging, stamping, casting, or powder metallurgy. During manufacturing, the frame 10 and middle plate 20 are first joined by die-casting, welding, hot isostatic pressing, forging, 3D printing, injection molding, or gluing to form a high-strength integral body. This integral body is then machined by CNC machining or other methods to complete the manufacture of the terminal structure.
