The technical solutions of the present invention will be clearly described in the following with reference to the accompanying drawings. It is obvious that the embodiments to be described are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

A terminal device provided by an embodiment of the present invention includes a button shell and an inner shell. A slide rail is disposed on the button shell, a sliding slot is disposed at a corresponding position of the inner shell, and the slide rail can slide along the sliding slot, so that the button shell and the inner shell are fixedly connected.

It can be understood that, herein, the slide rail disposed on the button shell and the sliding slot disposed on the inner shell may be in any shape, provided that the shape of the slide rail matches with the shape of the sliding slot, so that the slide rail can slide along the sliding slot. For example, when the slide rail has a recessed shape, the sliding slot needs to have a protruding portion to match with the recessed slide rail, and any fitting structures that enable the button shell and the inner shell to be fixedly connected fall within the protection scope of the present invention.

Further, the sliding slot disposed on the inner shell may be a through hole on the inner shell, and may also be a blind hole on the inner shell; and the slide rail is preferably disposed on an inner surface of the button shell, that is, the slide rail is disposed at a side of the button shell where bumps are set, so that the terminal device has a more beautiful appearance. In addition, the sliding slot may be formed from a steel sheet (or other metals) or plastic through molding, and the slide rail may be formed by a plastic through molding, so that the molding process is simple, requirements for manufacturing precision are not high, and the manufacturing cost is low.

It can be seen that, according to the embodiment of the present invention, the button shell and the inner shell can be connected without using an intermediate medium, and the button shell and the inner shell are fixedly connected by sliding between the slide rail on the button shell and the sliding slot on the inner shell, so that materials of the terminal device are saved, thereby simplifying an assembly process of the button shell and the inner shell of the terminal device.

In a specific embodiment, a terminal device includes a button shell 10 and an inner shell 20 . The button shell 10 has a structure shown in FIG. 1A , and the inner shell 20 has a structure shown in FIG. 1B .

At least one slide rail 101 is disposed at a side of the button shell 10 where bumps 102 are set, and a width of an end of the slide rail 101 close to the button shell 10 is smaller than a width of an outer end of the slide rail 101 .

Two sliding slots 201 - 1 and 202 - 2 that are connected to each other are disposed at corresponding positions of the inner shell 20 , where a hollow surface of a first sliding slot 201 - 1 on the inner shell 20 is not smaller than an outer end surface of the slide rail 101 , and a width of a second sliding slot 201 - 2 is not smaller than a width of an end of the slide rail 101 close to the button shell.

Physical buttons are disposed on an outer side surface of the button shell 10 , and on an inner side surface of the button shell 10 , a bump 102 is disposed at a corresponding position of each physical button, and the slide rail 101 is disposed at a side of the bump 102 . The slide rail 101 may be in any shape, for example, as shown in FIG. 2 , a width of an end 101 - 3 of the slide rail 101 close to the button shell is smaller than a width of an outer end 101 - 2 of the slide rail, so that a cross section of the slide rail 101 is in a “T” shape, or a platform shape, or other shapes with a wide upper end and a narrow lower end.

Multiple holes 202 are disposed on the inner shell 20 , so that the bumps 102 of the physical buttons can pass through the holes 202 on the inner shell 20 , and are connected to a corresponding circuit in the terminal device, thereby achieving operations on the terminal device by means of the physical buttons. In this embodiment, at least two sliding slots 201 - 1 and 201 - 2 that are connected to each other are further disposed on the inner shell 20 , so that a hollow surface of a first sliding slot 201 - 1 on the inner shell 20 is not smaller than an outer end surface 101 - 1 of the slide rail 101 , and a width of a second sliding slot 201 - 2 is not smaller than a width of an end 101 - 3 of the slide rail close to the button shell. The sliding slots 201 - 1 and 201 - 2 may also be in any shape, provided that the shape of the sliding slots 201 - 1 and 201 - 2 match with the shape of the slide rail 101 .

It should be noted that, optionally, the slide rail 101 is disposed at an edge of the button shell 10 as far as possible, and the sliding slots 201 - 1 and 201 - 2 are disposed at a corresponding position at an edge of the inner shell 20 , so that the setting of the slide rail 101 has no influence on other parts on the button shell 10 , and at the same time, the settings of the sliding slots 201 - 1 and 201 - 2 have no influence on other parts on the inner shell 20 .

In this way, in assembling the button shell 10 and the inner shell 20 , the outer end 101 - 2 of the slide rail disposed on the button shell 10 can be placed in the first sliding slot 201 - 1 on the inner shell 20 , and the end 101 - 3 of the slide rail close to the button shell slides into the second sliding slot 201 - 2 along the sliding slot 201 , so that the button shell 10 and the inner shell 20 are fixedly connected without using an intermediate medium.

If a width of the second sliding slot 201 - 2 is smaller than a width of the outer end 101 - 2 of the slide rail, the outer end 101 - 2 of the slide rail cannot easily slide out from the second sliding slot 201 - 2 , thereby further fastening connection of the button shell 10 and the inner shell 20 .

In another specific embodiment, referring to a structural diagram of a sliding slot 201 shown in FIG. 3 , in an inner shell 20 , besides a first sliding slot 201 - 1 and a second sliding slot 201 - 2 , a third sliding slot 201 - 3 connected to the second sliding slot 201 - 2 may be further set. A hollow surface of the third sliding slot 201 - 3 on the inner shell 20 is not smaller than an outer end surface 101 - 1 of a slide rail. In this way, in assembling the button shell 10 and the inner shell 20 , an outer end 101 - 2 of the slide rail disposed on the button shell 10 can be placed in the first sliding slot 201 - 1 or the third sliding slot 201 - 3 on the inner shell 20 , thereby further facilitating assembling the button shell 10 and the inner shell 20 .

Further, as is shown in FIGS. 4A and 4B , a stopping block 103 may be disposed at an end part of the button shell 10 , so that when the slide rail 101 slides along the sliding slot 201 , and the stopping block 103 blocks the inner shell 20 , the button shell 10 and the inner shell 20 are fixedly connected, that is, when the stopping block 103 blocks the inner shell 20 , an end 101 - 3 of the slide rail close to the button shell can just slide into the second sliding slot 201 - 2 .

Preferably, a groove may be disposed on the stopping block 103 , and a protrusion 203 matching with the groove is disposed at a corresponding position of the inner shell 20 , so that when the stopping block 103 blocks the inner shell 20 , the protrusion 203 is engaged with the groove.

Referring again to FIGS. 4A and 4B , in this embodiment, in assembling a button shell 10 and a inner shell 20 , first, an outer end 101 - 2 of a slide rail disposed on the button shell 10 needs to be placed in a first sliding slot 201 - 1 or third sliding slot 201 - 3 on an inner shell 20 , and bumps 102 on the button shell 10 need to be placed in holes 202 of the inner shell 20 .

When an end 101 - 3 of the slide rail close to the button shell slides along a sliding slot 201 , and a stopping block 103 blocks an inner shell 20 , a protrusion 203 on the inner shell 20 is engaged with a groove on the stopping block 103 , and at this time, the button shell 10 and the inner shell 20 are fixedly connected, that is, the end 101 - 3 of the slide rail close to the button shell slides into a second sliding slot 201 - 2 .

In disassembling the button shell 10 and the inner shell 20 , the groove of the stopping block 103 and the protrusion 203 on the inner shell 20 are disengaged, and the end 101 - 3 of the slide rail close to the button shell slides into the first sliding slot 201 - 1 or the third sliding slot 201 - 3 along the sliding slot 101 , that is, the slide rail 101 disposed on the button shell 10 is removed from the sliding slot 101 .
