Abstract

A handset device (10) includes a housing (20) and a battery cover (30) mounted on the housing. The housing includes a front wall (24), a rear wall (22), two sidewalls (26), and at least one bay cooperatively surrounded by the front wall, the rear wall, and the sidewalls. The front wall includes at least one first receiving portion (240) including a wedge-shaped first slidable groove (242) having a first inclination angle and a recessed portion (244) communicating with the first slidable groove. The rear wall includes at least one receiving groove (220). The battery cover includes at least one fastening protrusion (34) corresponding to the first receiving portion and at least one protrusion (32) received in the receiving groove. The fastening protrusion has an inclination angle equal to the first inclination angle and includes a hook located at an end thereof, abutting the recessed portion.

Claims

1. A handset device comprising:

a housing accommodating electronic elements, the housing comprising a front wall, a rear wall, and a pair of sidewalls, the front wall comprising at least one first receiving portion comprising a wedge-shaped first slidable groove having a first inclination angle and a recessed portion communicating with the first slidable groove, each of the sidewalls comprising at least one second receiving portion comprising a wedge-shaped second slidable groove having a second inclination angle and a fixing portion positioned over the second slidable groove, with the first inclination angle exceeding the second inclination angle; and

a battery cover mounted on the housing, the battery cover comprising at least one fastening protrusion corresponding to the first receiving portion and at least one pair of locking protrusions corresponding to the second receiving portions, the at least one fastening protrusion having a third inclination angle equal to the first inclination angle and comprising a hook located an end thereof, each of the locking protrusions having a fourth inclination angle equal to the second inclination angle;

wherein the hook of the fastening protrusion abuts the recessed portion, and the fixing portions abut the locking protrusions, respectively.

2. The handset device as claimed in claim 1, wherein each of the locking protrusions has an L-shaped profile.

3. The handset device as claimed in claim 2, wherein a bay is formed between an inner surface of the battery cover and each of the locking protrusions, and each of the fixing portions comprises a hook abutting the bay to fix the locking protrusion.

4. The handset device as claimed in claim 1, wherein the housing further comprises at least one receiving groove located at the rear wall, and the battery cover comprises at least one protrusion received in the receiving groove.

5. The handset device as claimed in claim 1, wherein each of the locking protrusions extends from the inner surface towards the housing, and the fastening protrusion extends from the inner surface towards the housing.

6. The handset device as claimed in claim 5, wherein an extending direction of the locking protrusion is the same as that of the fastening protrusion.

7. A handset device comprising:

a housing comprising a front wall, a rear wall, a pair of sidewalls, and at least one bay for accommodating a battery, the front wall, the rear wall and the sidewalls cooperatively surrounding the bay, the front wall comprising at least one first receiving portion comprising a wedge-shaped first slidable groove having a first inclination angle and a recessed portion communicating with the first slidable groove, the rear wall comprising at least one receiving groove; and

a battery cover mounted on the housing covering the bay, the battery cover comprising at least one fastening protrusion corresponding to the first receiving portion and at least one protrusion received in the receiving groove, the at least one fastening protrusion having an inclination angle equal to the first inclination angle and comprising a hook located an end thereof, the hook abutting the recessed portion.

8. The handset device as claimed in claim 7, wherein each of the sidewalls comprises at least one second receiving portion, and the battery cover comprises at least one pair of L-shaped locking protrusions corresponding to the second receiving portions.

9. The handset device as claimed in claim 8, wherein each of the second portions comprises a wedge-shaped second slidable groove having a second inclination angle and a fixing portion positioned over the second slidable groove.

10. The handset device as claimed in claim 9, wherein each of the locking protrusions and an inner surface of the battery cover cooperatively form a bay, and each of the fixing portions comprises a hook abutting a bottom of the bay to fix the locking portion.

11. The handset device as claimed in claim 9, wherein the first inclination angle of the first slidable groove exceeds the second inclination angle of the second slidable groove.

12. The handset device as claimed in claim 9, wherein each of the locking protrusions has an inclination angle equal to the second inclination angle.

13. The handset device as claimed in claim 8, wherein each of the locking protrusions extends from the inner surface towards the housing, and the fastening protrusion extends from the inner surface towards the housing in the same direction.

14. The handset device as claimed in claim 13, wherein an extending direction of the locking protrusion is the same as that of the fastening protrusion.
