Referring to fig. 2, in an exemplary embodiment, a mobile terminal is provided, which includes a display module 1, a front case assembly 2 and a battery cover 4 that are assembled and connected. Preceding shell subassembly 2 includes the fretwork portion 5 that is used for holding battery 3, fretwork portion 5 makes battery 3 press close to display module 1 is in order to shorten the distance of battery 3 lid with preceding shell subassembly 2.

The display module 1 comprises a display screen, a touch screen and the like, and the front shell component comprises a front shell connected with a battery cover 4 and necessary components of the mobile terminal such as a support, a mainboard and the like. The battery cover is connected with the front case to enclose the battery. In order to reduce the space waste, in the technical scheme of the present disclosure, a hollow portion 5 is disposed at the front shell assembly 2, so that the battery 3 is mounted in the hollow portion 5, and the thickness of the front shell assembly 2 and the gap 8 between the display module 1 and the front shell assembly 2 are fully utilized. Finally, the battery cover 4 is arranged next to the battery 3 and/or the front shell assembly 2, saving at least the assembly thickness of the entire battery 3 compared to the prior art. Further, placing the battery 3 in the hollow portion 5 may utilize the wall thickness of the front case assembly 2 and the gap 8 between the display module 1 and the front case assembly 2 as a reserved battery expansion space, so as to protect the battery and increase the volume of the battery, thereby increasing the battery capacity.

The battery cover 4 is disposed proximate to the battery 3 and/or the front housing assembly 2. When the thickness of the battery 3 needs to be increased to increase the battery capacity, the top surface of the battery 3 is higher than that of the front shell assembly 2, and the inner side surface of the battery cover 4 is arranged close to the battery 3. When the thickness of the battery 3 is lower than that of the front case assembly 2, the inner side surface of the battery cover 4 is disposed adjacent to the front case assembly 2. When the top surface of the battery 3 is flush or area flush with the top surface of the front case assembly 2, the inner side surface of the battery cover 3 is disposed next to the battery 3 and the front case assembly 2. Specifically, the thickness of the battery can be increased according to the expansion capacity of the battery.

The mobile terminal provided by the present disclosure is further described below by an embodiment.

The battery cover 4 is provided with a positioning part 6 connected with the battery 3 at a position corresponding to the hollow part 5, and the positioning part 6 is used for positioning the position of the battery 3 when the mobile terminal is assembled. For example, the battery 3 is fixed on the battery cover 4, so that the battery 3 and the battery cover 4 are assembled with the front case assembly 2 as a whole, thereby facilitating the assembly of the mobile terminal without assembling the battery first and then assembling the battery cover, and saving the assembly steps.

In one embodiment, as shown in fig. 3, the positioning part 6 includes a positioning groove formed on the inner surface of the battery cover 4, and an adhesive layer 61 for fixing the battery is disposed in the positioning groove. Namely, a positioning groove is formed in the battery cover 4 for positioning the battery, and a part of the battery 3 is accommodated in the positioning groove. The positioning groove may be a positioning groove concavely formed in the inner surface of the battery cover 4, or may be a positioning groove convexly formed in the inner surface of the battery cover 4 to fix and position the battery. The assembly gap between the battery cover 4 and the battery 3 is occupied when the positioning groove is protrudingly provided.

When the positioning groove is used for fixing the battery 3, a glue joint layer 61 is arranged in the positioning groove to fix the battery 3. The batteries 3 are fixed in the positioning grooves using, for example, a double-sided tape.

In another embodiment, as shown in fig. 4, the battery cover 4 is provided with a connecting member 7 connected to the battery 3 for fixing the battery 3. Namely, a connecting piece 7 capable of fixing the battery 3 is arranged on the battery cover 4, and the connecting piece 7 can replace the function of fixing the battery by the positioning part 6 and the adhesive layer 61.

For example, the connecting element 7 is provided as a limiting rib, the battery 3 is positioned by the connecting rib, and the battery 3 can be fixed in the limiting rib. So that the battery is assembled with the front case assembly 2 as a whole with the battery cover 4.

Further, the hollow portion 5 includes an expansion space for accommodating an increased volume of the battery 3 after expansion. The battery 3 expands during use or after a long period of use, and the volume of the battery 3 increases by about ten percent of the volume of the battery 3 itself after expansion.

The expansion space can better protect the battery. The expansion space of the present disclosure includes a gap between the display module 1 and the front case assembly 2. The clearance between the display module 1 and the front shell assembly 2 far exceeds the expansion space in the structural design in the prior art, so that the assembly space can be saved, and the battery can be better protected.

Because a gap is reserved between the display module 1 and the front shell assembly 2 in the thickness direction of the whole mobile terminal, a gap is reserved between the battery 3 and the battery cover. Placing the battery 3 in the hollow-out portion 5 can utilize the wall thickness of the front shell assembly 2 and the gap between the display module 1 and the front shell assembly 2 as a reserved battery expansion space, so that the battery is protected. And because the hollow part 5 and the expansion space thereof are arranged, the placing area of the battery is increased, so that the volume of the battery can be increased, and the capacity of the battery is increased.

Further, the mobile terminal further comprises a battery 3, and the battery 3 is arranged in the hollow part 5; the battery 3 is indirectly connected with the display module 1. Since the battery 3 generates heat during use, the temperature of the battery generally rises in the range of about 6 to 10. If the heat generated by the battery 3 is too large, the display quality of the display module 1 is affected to a certain extent, and the battery 3 and the display module 1 need to be insulated from each other. As an embodiment, a heat insulation layer (not shown) is disposed between the battery 3 and the display module 1. The heat insulation layer can be made of heat insulation materials, and can also be of other structures with heat insulation functions. Such as glass fibers, asbestos, rock wool, silicates, etc., novel thermal insulation materials, such as aerogel blankets, vacuum panels, etc.

In conclusion, the mobile terminal provided by the disclosure can be hollowed out at the front shell assembly corresponding to the battery, the wall thickness of the front shell assembly and the gap between the display module and the front shell assembly are saved, and the front shell assembly and the wall thickness of the front shell assembly are taken as the expansion space of the battery together, the expansion space far exceeds the battery expansion space reserved in the current structural design, and the battery is effectively protected and the battery capacity is increased. The battery cover is provided with the positioning part or the connecting part, so that the battery can be fixed and assembled with the battery cover as a whole, and the assembling steps are saved.

The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
