Referring to FIGS. 1-3, a portable electronic device 100 in accordance with an exemplary embodiment is illustrated. The portable electronic device 100 may be a mobile phone, a laptop, or a personal digital assistant. In this embodiment, the portable electronic device 100 is a mobile phone. The portable electronic device 100 includes a hollow shell 10, a display screen 20, a keypad 30, an image capturing assembly 40, and a signal procession circuit 50.
The display screen 20 and the keypad 30 are assembled in the outer surface of the shell 10. In this embodiment, the display screen 20 and the keypad 30 are adjacent to each other.
The shell 10 includes a top portion 101 (i.e., a head portion), the top portion 101 defines a first annular guiding slot 102 therein. The signal procession circuit 50 is mounted within the shell 10.
Also referring to FIG. 4, the portable electronic device 100 further includes a T-shaped connection plate 15 affixed on the top portion 101. The connecting plate 15 includes a first plate 152 and a second plate 154 perpendicular to the first plate 152. The first plate 152 is disposed on the top portion 101. A number of position holes 1522 are defined along a periphery of the first plate 152. A second annular guiding slot 1542 is defined on the second plate 154 and aligned with the first annular guiding slot 102. The connecting plate 15, the top portion 101 of the shell 10, the first annular guiding slot 102, and the second annular guiding slot 1542 cooperatively form a laid-down T-shaped groove 16. The image capturing assembly 40 is received in the T-shaped groove 16 and is slidable along the first annular guiding slot 102 and the second annular guiding slot 1542.
A first block 104 is positioned in the first annular guiding slot 102. A second block 17 is positioned in the second annular guiding slot 1542 and aligned with the first block 104. In this embodiment, the first block 104 and second block 17 are configured for limiting the sliding range of the image capturing assembly 40.
The camera module 42 includes an image sensor chip 422, a substrate 424, a lens module 426, and a flexible print circuit (FPC) 428.
The image sensor chip 422 is a charged coupled device (CCD), or a complementary metal-oxide-semiconductor transistor (CMOS). The image sensor chip 422 is configured to convert light signals received from the lens module 426 into digital electrical signals.
The substrate 424 consists of such materials as polyimide, ceramic, or glass fiber. The substrate 424 includes a supporting surface 4242 and a bottom surface 4244 facing away from the supporting surface 4242. The supporting surface 4242 is configured for engaging with the image sensor chip 422 and the lens module 426. The image sensor chip 422 is electrically mounted on the substrate 424. A number of bonding pads 4245 are disposed on the bottom surface 4244 of the substrate 424, the bonding pads 4245 are mechanically and electrically coupled to one end of the FPC 428 via a type of anisotropic conductive adhesive (ACA). The other end of the FPC 428 is electrically connected to the signal procession circuit 50 for processing images captured by the camera module 42.
The lens module 426 aligns with the image sensor chip 422, and includes a lens barrel 4262, a lens holder 4264 and a lens assembly 4266 received in the lens barrel 4262. The lens barrel 4262 is partially received in and engaged with the lens holder 4264. The lens holder 4264 is adhered to the supporting surface 4242 of the substrate 424 and receives the image sensor chip 422. In this embodiment, the substrate 424 is larger than the lens holder 4264. Two opposite peripheries 4246 of the substrate 424 are correspondingly received in the first annular guiding slot 102 and the second annular guiding slot 1542, and the lens module 426 appears to users via the laid-down T-shaped groove 16.
The biasing device 44 includes a hollow frame 442, a ball 444, and a spring 446. The frame 442 is disposed on the bottom surface 4244 of the substrate 442. In this embodiment, the frame 442 is made of elastic material. One end of the frame 442 away from the substrate 424 defines an opening 4420. In this embodiment, the opening 4420 is circular in shape, and the diameter of the opening 4420 is slightly less than that of the ball 444. The ball 444 and the spring 446 are received in the frame 442. The spring 446 urges against the ball 444, the ball 444 partially protrudes from the opening 4420 to the first plate 152.
In use, the image capturing assembly 40 can be slid by users in the T-shape groove 16. When users stop sliding the image capturing assembly 40, the ball 444 of the biasing device 44 is engagingly received in a position hole 1522 under the biasing force of the spring 446, which prevents the image capturing assembly 40 from sliding away automatically.
It will be understood that the above particular embodiments and methods are shown and described by way of illustration only. The principles and the features of the present invention may be employed in various and numerous embodiments thereof without departing from the scope of the invention as claimed. The above-described embodiments illustrate the scope of the invention but do not restrict the scope of the invention.
