Further, please refer to fig. 9, fig. 9 is a schematic partial sectional view of a housing assembly according to another embodiment of the present application; the difference between this embodiment and the embodiment in fig. 8 is that, in this embodiment, a third glue overflow groove 2213 is provided on the outer surface of the connecting portion 220 of the decoration 200 near the main body portion 210, and the third glue overflow groove 2213 is communicated with the glue dispensing groove 222; the end surface of the main body 210 facing the first surface 110 of the housing 100 is provided with a fourth glue overflow groove 2104, the fourth glue overflow groove 2104 is disposed near the outer surface of the connecting portion 220 and is communicated with a third glue overflow groove 2213 on the connecting portion 220, and the third glue overflow groove 2213 and the fourth glue overflow groove 2104 together form an upper glue overflow groove 204.

Optionally, referring to fig. 10 together, fig. 10 is a schematic structural bottom view of the decoration in the embodiment of fig. 9, in this embodiment, an end surface of the main body portion 210 facing the first surface 110 of the housing 100 is provided with an air discharge slot 2105, one end of the air discharge slot 2105 is communicated with the glue overflow slot 204, and the other end extends to the side surface 2106 of the main body portion 210 and is communicated with the side surface 2106 of the main body portion 210. The number of the air discharge slots 2105 is a plurality of air discharge slots, which are uniformly distributed around the circumference of the glue overflow slot 204, and is eight in the figure of the present embodiment, but the number is not limited specifically.

The present embodiment provides a new housing assembly structure, and the decoration 200 is adhered to the housing 100 (in this embodiment, a battery cover) by dispensing glue 102 in the dispensing groove 222. The decorative piece 200 and the shell 100 can be provided with a groove in a CNC (computerized numerical control) mode, the upper glue overflow groove 204 and the lower glue overflow groove 103 are symmetrically formed, redundant glue is contained, a hanging table is formed after solidification, the decorative piece is riveted with the shell 100, and the bonding strength of the decorative piece 200 is enhanced. Referring to fig. 10, in order to ensure the positioning accuracy of the decoration 200 and the housing 100, a positioning gap 105 is reserved between the two for positioning, the positioning gap 105 is generally 0.05mm to 0.1mm, but the positioning gap 105 is too small to be filled with glue, and the glue cannot reach a good bonding strength, so that the glue dispensing groove 222 can be processed on the decoration 200 in a CNC manner for filling the glue, and a plurality of air discharge grooves 2105 are formed on the lower flange of the decoration 200 for discharging air, so as to ensure that the glue can completely fill the upper glue discharge groove 204.

Referring to fig. 11, fig. 11 is a schematic structural diagram of a case deformed by a force in the conventional art; when the shell 100 is made of composite plates and the like, the shell is easily extruded by an internal structure, the shell 100 is easily arched upwards to deform, stress concentration can occur at the bottom position where the shell 100 is in contact with the decorating part 200, the glue in the lower glue flowing groove 103 bears shear stress, the glue is glued and the glue is bonded to lose efficacy, and the decorating part 200 falls off. The dotted line in the figure indicates the position state where the housing 100 is deformed, as follows.

The technical scheme in the embodiment of the present application provides a new anti-drop structure for a housing assembly, that is, after dispensing, a connecting plate 300 (made of glass fiber plate) is covered on the end surface of the decoration 200 and the inner side of the housing 100. When the housing 100 is arched and deformed, the deformation of the area near the decoration 200 is reduced due to the reinforcement effect of the connection plate 300 (please refer to fig. 12, fig. 12 is a structural schematic diagram of the deformation of the housing assembly under stress in this embodiment, it is obvious that, compared with the structure of fig. 11 in which the connection plate 300 is not provided in the conventional technology, the deformation of the housing 100 in this embodiment is significantly reduced, and the lower end of the decoration 200 will abut against the connection plate 300, thereby further inhibiting the deformation of the housing 100 in the plate structure, so the adhesive surface stress is small, and the decoration 200 is not easily peeled off to cause the falling off of the decoration 200. And in the process of covering the connecting plate 300 after dispensing, the glue is pressed to fill the gap (positioning gap 105) between the decorating part 200 and the shell 100 more easily, so that a good bonding effect is realized. Therefore, the dispensing method using the connecting plate 300 is advantageous in preventing the case 100 (especially, the battery cover made of a flexible plate material) from being detached from the exterior decoration 200.

In the case assembly structure of the embodiment, the strength of the case 100 (battery cover) is locally enhanced by covering the connection plate 300 after dispensing, the deformation of the board of the case 100 is reduced, stress balance is adopted, the stress of the adhesive surface is reduced, the phenomenon that the decorative part 200 and the adhesive surface of the battery cover are peeled off and fall off is avoided, and the reliability of the electronic device structure is improved.

The above description is only a part of the embodiments of the present invention, and not intended to limit the scope of the present invention, and all equivalent devices or equivalent processes performed by the present invention through the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
