Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
As shown in fig. 3 and 4, the present invention provides a housing 10 and a mobile terminal including the same, wherein the housing 10 includes a cover plate, a middle frame support 1 and a frame plate assembly 3, which are sequentially stacked from top to bottom, wherein the cover plate may be a battery cover 2 or other cover plates applied to the mobile terminal, and the frame plate assembly 3 may be composed of a plurality of parts such as a plate and a frame. Be provided with coupling assembling between center support 1 and the deckle board subassembly 3, center support 1 is fixed in deckle board subassembly 3 with mechanical connection's mode through this coupling assembling, coupling assembling prevents that center support 1 from arching towards the apron because of the internal stress, cause the apron evagination, influence the outward appearance, and this kind of fixed mode of center support 1 need not use glue, the manufacturing cost of casing 10 has been reduced and the assembly process of casing 10 has been simplified, when carrying out after-sale maintenance to mobile terminal, also need not to mend gluey, thereby cost of maintenance and the degree of difficulty have been reduced.
Coupling assembling includes buckle 4 and the card hole 5 of mutual lock, and buckle 4 and one in the card hole 5 set up in center frame support 1, another set up in deckle-board subassembly 3. The middle frame support 1 is connected with the frame plate component 3 through the buckle 4, fixed connection of the middle frame support and the frame plate component can be achieved only through simple buckling, dismounting is convenient, a glue dispensing step is omitted when the shell 10 is mounted, glue dispensing is conducted again after the glue dispensing step is finished without destroying glue dispensing points during dismounting after sale, maintenance difficulty and cost are reduced, the structure of the buckle 4 is simple, and forming difficulty is low.
In the present embodiment, as shown in fig. 4, the frame plate assembly 3 includes a shield case 31 and a main plate 32. The clamping hole 5 is arranged on the shielding cover 31 of the frame plate component 3, and the buckle 4 extends from the middle frame support 1 to the clamping hole 5. This is because the frame plate assembly 3, especially the main board 32, has many electronic components and is inconvenient to be provided with the buckle 4, so that the buckle 4 is arranged on the middle frame support 1, and the buckle 4 is clamped in the clamping hole 5 of the shielding case 31 to correct the deformation of the middle frame support 1. The shielding case 31 has a simple structure, and is structurally modified to involve fewer other parts, so that the structural influence on the housing 10 and the whole mobile terminal is small. In other preferred embodiments, the latch 4 may be disposed on the shield case 31 or other parts of the frame plate assembly 3 (e.g., the main plate 32), and the latch hole 5 may be disposed on the middle frame bracket 1.
Referring specifically to fig. 5 and 6, the frame plate assembly 3 has a fixing portion 311 protruding toward the middle frame bracket 1, and the card hole 5 is provided on the fixing portion 311. Because the frame plate component 3 is provided with the electronic element, it is inconvenient to directly set the clamping hole 5 thereon, so that the space between the frame plate component 3 and the middle frame bracket 1 is fully utilized, the fixing part 311 is arranged in the space, so that the clamping hole 5 can be arranged on the fixing part 311, the electronic element on the frame plate component 3 is not influenced, and the capability of bearing load of the convex fixing part 311 is better.
In the present embodiment, the fixing portion 311 is disposed on the side portion of the shielding case 31, and the fixing portion 311 is a folded structure, that is, the shielding case 31 is bent to form the fixing portion 311. The folded structure is provided with a through hole to form a clamping hole 5. In the present embodiment, the fixing portion 311 is bent at the edge of the shielding case 31 to form a door shape or an arch shape, so that the structural change of the whole frame plate assembly 3 is small, and since the shielding case 31 is a thin plate structure, the fixing portion 311 is not difficult to process, and is easy to implement, and the electromagnetic shielding effect of the shielding case 31 is not affected. The fixing portion 311 is integrally provided with the shield case 31, and has a relatively firm structure, which is advantageous for applying a corrective force to the arching of the center frame bracket 1. The shield cover 31 is provided with mounting holes 312 at both sides of the fixing portion 311, and the shield cover 31 is fixed to the main board 32 by the mounting holes 312 (for example, using screws or bolts) to improve the stability of the fixing portion 311, so that the fixing portion 311 can bear the deformation force generated by the middle frame support 1, and the fixing portion 311 is prevented from being deformed due to insufficient rigidity of the shield cover 31.
In other preferred embodiments, the card hole 5 can be disposed on other parts of the frame plate assembly 3 (such as the main plate 32), and the position of the card hole 5 can be adjusted by those skilled in the art according to the actual situation.
In this embodiment, buckle 4 and center support 1 integrated into one piece, it is adjacent to dodge hole 11 and buckle 4, dodge hole 11 except can holding fixed part 311, still make buckle 4 crooked more easily simultaneously, be convenient for buckle 4 and the installation of calorie hole 5. The end of the buckle 4 is provided with a convex part 41, the extending direction of the convex part 41 is parallel to the tiling direction of the middle frame support 1, and the surface of the convex part 41 facing to one side of the middle frame support 1 is clamped on the clamping hole 5 to correct the deformation of the middle frame support 1. As shown in fig. 6, the protrusion 41 is wedge-shaped, and the upper and lower surfaces of the protrusion 41 are inclined surfaces, so that the wedge-shaped protrusion 41 is easy to be inserted into the card hole 5.
Because the deflection of center frame support 1 in the middle part is the biggest, coupling assembling connects in the middle part of center frame support 1 to the best effect of realization to center frame support 1 deformation correction.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
