For example, in the examples of fig. 1-5, 10-13, and 14-30, α1May be 0 deg., the inner surface of the first casing 1 may be formed as a plane, and the inner wall 310 of the first sub-middle frame may be perpendicular to the inner surface of the first casing 1, and for another example, α1May be 30 deg., in the first sub-middle frame311, the inner wall 310 of the first sub-middle rim extends obliquely outwardly in a direction away from the first housing 1, facilitating a design of the first housing component 4 of unequal thickness, e.g. α1The angle may be 30 °, on the cutting plane of the first sub middle frame 311, the inner wall 310 of the first sub middle frame extends in a direction away from the first casing 1, and is inclined inward, at this time, the first middle frame 31 may substantially form an inverted structure, and the outer wall of the first sub middle frame 311 may form a plane, so that the width of the first sub middle frame 311 in the left-right direction is gradually increased from front to back, and thus the first casing assembly 4 may implement a design with different thicknesses, which breaks the limitation that the conventional hot bending process can only implement a design with the same thickness, and simultaneously avoids CNC overcutting; when the housing assembly 100 is applied to an electronic device, the display module 101 can be attached to the first housing assembly 4, especially the inner wall 310 of the first sub-middle frame, more tightly, so that the electronic device has a better light and shadow effect.
Here, it should be noted that the direction "outside" may refer to a direction away from the central axis 10 of the first housing, and the opposite direction thereof is defined as "inside".
Specifically, the first casing 1 and the first middle frame 31 are both glass pieces, and a fusion surface between the first casing 1 and the first middle frame 31 is formed with a silicon-oxygen-silicon bond, so that a covalent bond is formed between the first casing 1 and the first middle frame 31, and compared with the conventional technology, the method has the advantages that the first casing 1 and the first middle frame 31 are heated to a temperature higher than the melting temperature of glass, and a silica framework on the fusion surface between the first casing 1 and the first middle frame 31 is damaged to avoid generation of a complete silica framework, and a new silica framework is formed at a contact part between the first casing 1 and the first middle frame 31, so that the fusion strength of the first casing 1 and the first middle frame 31 is improved, and meanwhile, the uniformity inside the first casing assembly 4 is improved, and further, the optical performance of the first casing assembly 4 is improved.

Therefore, when the first shell 1 and the first middle frame 31 are fused, a new silica structural framework is easier to build, and ions are favorably dissociated from the first shell 1 or the first middle frame 31 and filled in the new framework of the composite surface.
The composite surface is a contact surface formed by contacting the surface of the first casing 1 after the activation treatment with the surface of the first middle frame 31 after the activation treatment.
In the description of the present invention, the main purpose of the activation treatment is to add two glass pieces, such as silicon dangling bonds and oxygen dangling bonds on the surfaces of the first shell 1 and the first middle frame 31, when in recombination (i.e. fusion), the old silica structural framework on the surface of the glass piece is more prone to fracture, the new silica structural framework generated on the composite surface is more prone to build up, and ions are favorably dissociated from the old framework and filled into the new framework on the composite surface, so as to promote the subsequent fusion process; wherein the water drop angle of the activated surface is not more than 10 °, or the surface roughness of the activated surface is not more than 0.2 μm; the activation treatment can be carried out by adopting an activation solution at room temperature to 200 ℃, wherein the activation solution is acidic or alkaline, for example, the pH value of the activation solution is not more than 4, or the pH value of the activation solution is 10-14.

Therefore, the inner wall of the second middle frame 32 and the outer wall of the second middle frame 32 have various structural forms, so that the inner wall and the outer wall of the second shell assembly have diversity, the limitation that the traditional technology cannot be realized by adopting CNC (computer numerical control) processing is broken through, the inner wall and the outer wall of the second shell assembly are diversified, the applicability of the second shell assembly is improved, the inner wall and the outer wall of the second shell assembly can realize unequal arc design, the shape of the second shell assembly has more stereoscopic impression, the structure of the shell assembly 100 is diversified, the applicability of the shell assembly 100 is further improved, and the shape of the shell assembly 100 has more stereoscopic impression; when the housing assembly 100 is applied to an electronic device, differentiation can be realized with the housing assembly 100 of the conventional technology, and the experience effect of a user is further effectively improved.

Here, the "inner wall of the second middle frame 32" may refer to a side surface of the second middle frame 32 adjacent to the central axis of the second casing 2, the "outer wall of the second middle frame 32" may refer to a side surface of the second middle frame 32 away from the central axis of the second casing 2, the inner wall of the second middle frame 32 is disposed opposite to the outer wall of the second middle frame 32, and the central axis of the second casing 2 may pass through the center of the second casing 2 and be parallel to the thickness direction of the second casing 2.
Alternatively, in the example of fig. 18 to 25, there are two second sub middle frames 321, each second sub middle frame 321 extends along two long sides of the second casing 2, the two second sub middle frames 321 are parallel, an outer wall of each second sub middle frame 321 may be disposed flush with a corresponding edge of the second casing 2, lengths of the two second sub middle frames 321 may be equal, and the length of the two second sub middle frames 321 may be equal to that of the long side of the second casing 2, that is, two ends of the length of each second sub middle frame 321 are respectively disposed in alignment with two ends of the long side of the corresponding second casing 2, so that the second casing assembly has a neat and beautiful structure. In the example of fig. 26 to 30, the number of the second sub middle frames 321 is four, and four second sub middle frames 321 are connected end to end in sequence, so that the second middle frame 32 is formed substantially in a ring-shaped structure, and the outer wall of each second sub middle frame 321 may be disposed flush with the corresponding edge of the second housing 2.
In some alternative embodiments of the present invention, the inner wall 320 of the second sub middle frame is formed as a second curved section on the cutting plane of the second sub middle frame 321, wherein the cutting plane of the second sub middle frame 321 is a plane perpendicular to the extending direction of the second sub middle frame 321, that is, the cutting plane of the second sub middle frame 321 may be the cross section of the second sub middle frame 321, and the cutting plane of the second sub middle frame 321 is parallel to the thickness direction of the second shell 2. The second curve segment has good diversity, so that the structural diversity design of the second shell assembly formed by the second shell 2 and the second middle frame 32 is further ensured; when the housing assembly 100 is applied to the electronic device and the second housing 2 is used for the screen cover plate of the electronic device, the matching of the display module 101 and the second housing assembly is more flexible, the electronic device can present a better light and shadow effect, and the user experience is improved. Wherein the first curved section may be a smooth curved section, for example, the second curved section may be continuous in G1 for ease of processing.

Because the included angle between the second straight-line section and the central axis of the second shell 2 has a plurality of selectable values, the structure diversification design of the second shell component is further ensured.
For example, in the example of fig. 18-30, α2May be 0 deg., the inner surface of the second casing 2 may be formed as a plane, and the inner wall 320 of the second middle frame may be perpendicular to the inner surface of the second casing 2, and for example, α2Which may be 30 deg., and an inner wall 320 of the second middle frame extending obliquely outward in a direction away from the second casing 2 in a sectional plane of the second sub-middle frame 321, facilitates a design of the second casing assembly with unequal thickness, as further example α2And may be 30 °, the inner wall 320 of the second sub-middle frame extends obliquely inward in a direction away from the second housing 2 on the second plane, at this time, the second sub-middle frame 321 may substantially form an inverted structure, and the outer wall of the second sub-middle frame 321 may form a plane, so that the width of the second sub-middle frame 321 in the left-right direction is gradually increased from front to back, so that the housing assembly may implement a design of unequal thickness, the limitation that the conventional hot bending process can only implement a design of equal thickness is broken, and CNC overcutting is avoided.

For example, a part of the surface of the second casing 2 may be subjected to an activation treatment to form an activated surface, so that the above-mentioned part of the surface of the second casing 2 forms reactive silicon and reactive oxygen, and a part of the surface of the second middle frame 32 may be subjected to an activation treatment to form an activated surface, so that the above-mentioned part of the surface of the second middle frame 32 forms reactive silicon and reactive oxygen; when the second casing 2 and the second middle frame 32 are fused, the activated surface of the second casing 2 is brought into contact with the activated surface of the second middle frame 32, so that a fused surface between the second casing 2 and the second middle frame 32 is formed with silicon-oxygen-silicon bonds, whereby the second casing 2 and the second middle frame 32 are formed into a unitary structure. Therefore, when the second shell 2 and the second middle frame 32 are fused, a new silica structural framework is easier to build, and ions are favorably dissociated from the second shell 2 or the second middle frame 32 and are filled in the new framework of the composite surface.
The composite surface is a contact surface formed by contacting the surface of the second casing 2 after the activation treatment with the surface of the second middle frame 32 after the activation treatment.
Further, in the example of fig. 18 to 21 and 26 to 30, the first case member 4 and the second case member each form an outer right angle, that is, the outer surface of the first case 1 and the outer peripheral wall of the first case 1 may be directly and vertically connected, and the outer surface of the second case 2 and the outer peripheral wall of the second case 2 may be directly and vertically connected. In the example of fig. 22 to 25, neither the first housing element 4 nor the second housing element is formed with an outer right angle, the outer surface of the first housing element 4 and the outer peripheral wall of the first housing element 4 may be smoothly transitioned by a first transition curved surface, and the outer surface of the second housing element and the outer peripheral wall of the second housing element may be smoothly transitioned by a second transition curved surface, the first transition curved surface is formed as a transition curved section on the section plane of the first sub-middle frame 311, and the second transition curved surface is formed as a transition curved section on the section plane of the second sub-middle frame 321; the transition curve section can at least comprise one curve section, the curve section can be an arc line section, and the radius r of the arc line section satisfies that r is more than or equal to 0.5mm and less than or equal to 8 mm.
