Protective cover assembly for camera module and portable electronic device using same
View Patent ↗A protective cover assembly is mounted within a portable electronic device. The portable electronic device defines a through hole. The protective cover assembly includes a resisting portion including a first positioning portion and a second positioning portion, a shielding cover and an elastic member offering an elastic force to make the resisting portion abut against the shielding cover. When the shielding cover resisting the first positioning portion, the shielding cover shields the through hole. When the shielding cover resisting the second positioning portion, the shielding cover exposes the through hole.
1. A protective cover assembly mounted within a portable electronic device, the portable electronic device defines a through hole, the protecting cover assembly comprising:
a transmission device including a first positioning portion, a second positioning portion, and an eccentric wheel defining a resisting peripheral wall, the first positioning portion and the second positioning portion formed on the resisting peripheral wall;
a shielding cover abutting against and slidable relative to the transmission device between the first positioning portion and the second positioning portion so as to selectively cover or shield the through hole, the shielding cover comprising a shielding portion and a resisting portion connected to the shielding portion; and
an elastic member offering an elastic force to urge the resisting portion of the shielding cover to closely abut the eccentric wheel.
2. The protective cover assembly as claimed in claim 1 , wherein the eccentric wheel is driven by a power generating device.
3. The protective cover assembly as claimed in claim 1 , wherein the shielding portion shields the through hole, the resisting portion is slidably mounted within the portable electronic device.
4. The protective cover assembly as claimed in claim 3 , wherein a fastening block protrudes from the portable electronic device, the fastening block defines a sliding slot, the resisting portion is slidably received in the sliding slot.
5. The protective cover assembly as claimed in claim 4 , wherein the resisting portion defines a receiving cavity, the receiving cavity receives the elastic member, one end of the elastic member abuts against the fastening block, the other against the resisting portion.
6. A portable electronic device including a housing and a protective cover assembly, the protective cover assembly mounted within the housing, the housing defining a through hole, the protective cover assembly comprising:
a transmission device including a first positioning portion, a second positioning portion, and an eccentric wheel defining a resisting peripheral wall, the first positioning portion and the second positioning portion formed on the resisting peripheral wall;
a shielding cover abutting against and slidable relative to the transmission device between the first positioning portion and the second positioning portion so as to selectively cover or shield the through hole, the shielding cover comprising a shielding portion and a resisting portion connected to the shielding portion; and
an elastic member offering an elastic force to urge the resisting portion of the shielding cover to closely abut the eccentric wheel.
7. The protective cover assembly as claimed in claim 6 , wherein the eccentric wheel is driven by a power generating device.
8. The protective cover assembly as claimed in claim 6 , wherein the shielding portion shields the through hole, the resisting portion is slidably mounted within the housing.
9. The protective cover assembly as claimed in claim 8 , wherein a fastening block protrudes from the housing, the fastening block defines a sliding slot, the resisting portion is slidably received in the sliding slot.
10. The protective cover assembly as claimed in claim 9 , wherein the resisting portion defines a receiving cavity, the receiving cavity receives the elastic member, the cross-sectional area of the elastic member is larger than the resisting portion, one end of the elastic member abuts against the fastening block, the other against the resisting portion.
