[0027] Please see Figure 2 and Figure 3The frame 10 is substantially rectangular in structure, and has an outer circumferential surface 11 and an inner circumferential surface 12. The inner circumferential surface 12 is provided with a glue pulling groove 13 for accommodating an injection molded body (not shown) to enable the injection molded body to be combined with the frame 10. The glue pulling groove 13 includes a first groove 131 recessed from the inner circumferential surface 12 towards the outer circumferential surface 11, and a second groove 132 located between the inner circumferential surface 12 and the outer circumferential surface 11 and communicating with the first groove 131. The glue pulling groove 13 can extend to the inside of the frame 10 through the second groove 132. It can be understood that the extension direction of the first groove 131 is perpendicular to the inner circumferential surface 12, and the extension direction of the second groove 132 is parallel to the inner circumferential surface 12.

[0028] In this embodiment, the frame 10 is made of a metal material and is formed by 3D printing. The glue pulling groove 13 is integrally formed on the inner circumferential surface 12 during 3D printing of the frame 10. In this embodiment, the first groove 131 is provided with the second groove 132 above and below the inner circumferential surface 12. It can be understood that in other embodiments, the second groove 132 can be provided only above or below the first groove 131. The number of glue pulling grooves 13 can be multiple, and the shapes of the multiple glue pulling grooves 13 can be substantially the same.

[0029] It can be understood that the inner circumferential surface 12 of the frame 10 is also integrally formed with other groove structures, such as rectangular grooves, square grooves, circular grooves, oval grooves or other shaped groove structures, which can be designed according to actual conditions, and will not be described in detail in this embodiment.

[0030] In this embodiment, the groove bottom of the second groove 132 away from the first groove 131 is arc-shaped and recessed away from the first groove 131. The cross-sectional shape of the first groove 131 perpendicular to the outer circumferential surface 11 and the inner circumferential surface 12 is quadrilateral, and the cross-sectional shape of the second groove 132 perpendicular to the outer circumferential surface 11 and the inner circumferential surface 12 is circular V-shaped. In this way, by limiting the cross-sectional shape of the first groove 131, the groove bottom of the second groove 132 and the second groove 132, the first aspect is to increase the combined area of the injection molded body and the frame 10, thereby further improving the combined effect of the injection molded body and the frame 10, the second aspect is to extend the depth of the second groove 132 in the frame 10, thereby improving the waterproof effect after the injection molded body is combined with the frame 10, and the third aspect is that the volume of the injection molded body that can be accommodated by the glue pulling groove 13 is larger. The injection molded body formed by injection molding makes the injection molded body at the glue pulling groove 13 and the frame 10 more closely and reliably combined, thereby solving the cracking and waterproofing problems of the frame 10 antenna.

[0031] In this embodiment, the material of the frame 10 can be titanium alloy material, aluminum alloy material or stainless steel material. In this way, by limiting the material of the frame 10, the material used by the frame 10 can be printed by 3D printing, the strength of the frame 10 can be ensured, and the frame 10 can meet the requirements of high brightness.

In this way, by limiting part of the frame 10 as a hollow structure, on the one hand, it is beneficial to reduce the weight of the frame 10, and on the other hand, it is beneficial to further reduce the cost of metal materials.

[0033] The middle plate 20 has a first surface 21, a second surface 22 provided opposite to the first surface 21, and an outer side surface 23 connected between the first surface 21 and the second surface 22, and at least part of the outer side surface 23 is connected with the inner circumferential surface 12. Among them, the first surface 21 and the second surface 22 can be a plane, or a non-plane with protrusions and the like, and the outer side surface 23 can be a rectangular plane or a special-shaped surface, which is not limited in the embodiment.

[0034] In the embodiment, the material of the middle plate 20 is a metal material, and the material of the middle plate 20 can be a titanium alloy material, an aluminum alloy material or a stainless steel material. The middle plate 20 can be 3D printed, and the middle plate 20 and the frame 10 can be integrally 3D printed. There is a gap 30 between part of the outer side surface 23 and the inner circumferential surface 12, and the middle plate 20 is provided with a glue pulling hole 24, which is used to accommodate an injection molded injection body so that the injection body can also be combined with the middle plate 20, improving the combination effect of the whole shell 100 and the injection body. The glue pulling hole 24 includes a first hole 241 opened on the first surface 21 and a second hole 242 opened on the outer side surface 23 and communicated with the first hole 241, and the second hole 242 is also communicated with the gap 30. In the embodiment, the cross-sectional shape of the first hole 241 parallel to the first surface 21 and the second surface 22 is special-shaped, which is connected by an arc and a straight line, that is, the first hole 241 is a special-shaped hole, and the cross-sectional shape of the second hole 242 parallel to the outer side surface 23 is quadrilateral, that is, the second hole 242 is a rectangular hole. In this way, by providing the above glue pulling hole 24, the injection body can also be combined with the middle plate 20, improving the combination effect of the whole shell 100 and the injection body. In addition, by limiting the middle plate 20 and the frame 10 to be integrally 3D printed, it is beneficial to reduce the use amount of CNC processing and tools, thereby reducing the development cost of the shell 100.

[0035] It can be understood that, in other embodiments, the first hole 241 can also be a polygonal hole or a circular hole, or the first hole 241 can also be combined by a plurality of holes, and the plurality of holes can be combined into a specific character, letter, pattern or the like, which can be designed according to actual conditions, and the embodiments of the present application do not make specific limitations.

[0036] It can be understood that, in other embodiments, the middle plate 20 can also be punched or die-cast, and at least part of the outer side surface 23 and the inner circumferential surface 12 can be welded or riveted. Alternatively, at least part of the outer side surface 23 and the inner circumferential surface 12 can also be connected by screws.

[0038] The shell 100 provided by the embodiments of the present application can extend the pull glue groove 13 to the inside of the frame 10 through the second groove 132 to improve the combination effect of the injection molding body and the frame 10, and the frame 10 is formed by 3D printing, which is conducive to forming the pull glue groove 13. Since the frame 10 and the pull glue groove 13 are formed by 3D printing, the problems of CNC machining and tools do not need to be considered, the use amount of CNC machining and tools is reduced, the CNC machining time is saved, and the development cost of the shell 100 is reduced. In addition, since the pull glue groove 13 can be directly formed on the inner circumferential surface 12 of the frame 10 by 3D printing, it is not limited by space, and the pull glue groove 13 of any position, shape and size can be formed according to the needs of structural design. The frame 10 with a complex structure can be manufactured and the weight of the frame 10 is reduced, so that the shell 100 has the characteristics of being complex, light and meeting the strength requirements, and meets the requirements of high-brightness, light and thin texture of the appearance of the shell 100. In addition, the pull glue groove 13 does not need to be machined by CNC machining and tools, which reduces the waste of metal materials and reduces the material cost.

In this way, by limiting the pull-tab groove 13 to further comprise the third groove 133, the structure of the 3D-printed pull-tab groove 13 is flexible and variable, which is conducive to improving the combination effect of the frame 10 and the injection body.

[0040] The electronic device provided in the embodiment of the present application comprises the shell 100, 200 and the injection body, the injection body is connected with the frame 10 and the middle plate 20, and part of the injection body is embedded in the pull-tab groove 13 of the frame 10, wherein the injection body is connected with the frame 10 and the middle plate 20 by injection molding.
