Folding electronic device with digital camera

The present invention relates to a folding electronic device, and more particularly to a folding electronic device having a digital camera.

With the development of wireless communication and information processing technology, electronic devices such as mobile phones and PDAs (Personal Digital Assistants) are becoming more and more popular, and products with additional functions added to electronic devices are emerging, such as electronic devices with digital cameras. .

Since the birth of the mobile phone with shooting function, the resolution of the digital camera has increased from the original 100,000 pixels to 300,000 pixels. Currently, the mobile phone with 1 million pixel digital camera has been put on the market, and has 200 Mobile phones with 10,000 or even 3 million digital cameras have also appeared on the market. However, due to the limitation of volume, the digital cameras on most mobile phones currently have a fixed focal length, and the distance between the lens groups and between the lens group and the image sensor is fixed, that is, the focal length f and the image distance q are both fixed. The value is based on the optical formula 1/p+1/q=1/f, and the object distance p of the shooting target is also fixed. If the position of the subject is beyond the range of the subject distance of the lens, the captured image will become blurred, thus greatly limiting the viewing range.

In view of the above-mentioned short focal length lens, the solution of some digital cameras adopts an amplification interpolation method to amplify the digital signal, but this only enlarges the original small area, and there is no new information increase, so it is practical. Not very sexual.

Relatively speaking, from the lens principle, this problem can be solved to a large extent by changing the focal length or image distance of the digital camera lens. When the shooting target exceeds the predetermined object distance range, a new object distance suitable for the target is obtained by changing the focal length or the image distance, thereby ensuring image quality.

In view of the above, it is necessary to provide a folding electronic device with a digital camera having a focusing function.

A folding electronic device with a digital camera includes a body, a cover, a hinge, and a lens module. The body and the cover are rotatably connected by the hinge. The lens module includes a lens group, a lens barrel and a lens holder. The lens assembly is mounted in the lens barrel, and the lens barrel is assembled in the lens holder by a threaded fit. One end of the cover body and the hinge is provided with a tooth pattern, and the body is provided with a tooth opposite to the tooth surface of the cover body. The lens module is disposed in the body, and a gear is disposed at one end of the lens holder, and the gear is exposed by the opening and cooperates with the tooth on the cover.

Compared with the prior art, the folding electronic device with a digital camera rotates the cover body, and the lens holder rotates by the cooperation of the ribs and the gears to achieve focusing, and the objects near and far can be clearly focused when photographed. Improve image quality on the imaging surface.

The preferred embodiment of the present invention discloses a folding electronic device with a digital camera, which can be a mobile phone, a PDA, etc., and the mobile phone is taken as an example for description.

Referring to the first, second and third figures, the mobile phone with the digital camera of the preferred embodiment comprises a body 1, a cover 2, a hinge 3, a lens module 4 and an image sensor 5. The body 1 and the cover 2 are rotatably connected by a hinge 3.

A keyboard 13 is provided on the body 1. An opening 112 is formed at one end of the first housing 11 and connected to the hinge 3. A hole 121 is defined in the sidewall of the second housing 12, and the lens module 4 is exposed through the hole 121. The second housing 12 is provided with a seat 122 for supporting the lens module 4. A through hole 124 is defined in the support 122 and corresponds to the hole 121 and penetrates. A recess 126 is defined in the through hole 124.

The cover 2 includes a housing 21, an outer screen 22, and an inner screen 24. The outer screen 22 is disposed on the outer surface of the cover body 2, and the inner screen 24 is disposed on the inner surface of the cover body 2, wherein the outer surface refers to the surface exposed when the cover body 2 is closed relative to the body 1, and the inner surface is referred to as The surface of the cover 2 that is in contact with the body 1 when it is closed relative to the body 1. On the housing 21, a tooth 212 is provided at one end of the connection with the hinge 3.

Referring to the third and fourth figures, the lens module 4 includes a lens group 41, a lens barrel 44 and a lens holder 42. The lens group 41 is fitted in the lens barrel 44. The outer surface of the lens barrel 44 is provided with an external thread 441. The inner surface of the lens holder 42 is provided with an internal thread 421. The lens barrel 44 is fitted into the lens holder 42 by screwing, and can be screwed in and out with respect to the lens holder 42. A convex portion 442 is provided on the side of the lens barrel 44. The outer surface of one end of the lens holder 42 away from the lens barrel 44 is provided with a gear 422 which can cooperate with the tooth pattern 212 on the cover body 2. When the lens module 4 is mounted on the body 1, the lens barrel 44 is mounted in the through hole 124, and the convex portion 442 on the lens barrel 44 is slidably engaged with the concave portion 126 on the support 122, and the lens holder 42 is partially received in the through hole. In the hole 124, the gear 422 is exposed outside the through hole 124. The gear 422 is exposed by the opening 112 in the first housing 11 to cooperate with the rib 212 on the cover 2.

The image sensor 5 is disposed in the body 1 and corresponds to the lens module 4, and is connected to the printed circuit board in the body 1 by a flexible circuit board (not shown). The image sensor 5 can be fixed to the second housing 12 or fixed to the lens holder 42. The image sensor 5 can be a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor.

When the folding electronic device with the digital camera of the present invention is used for photographing, when the cover 2 is closed with respect to the body 1, it is suitable for the far shot, and the lens module 4 focuses the distant scene on the image sensor 5. The photographer can preview the framing by the external screen 22. The cover body 2 is opened, and the rib 212 cooperates with the gear 422 to drive the lens holder 42 to rotate, because the convex portion 442 on the lens barrel 44 is restricted by the groove 126 in the through hole 124, and the thread outside the surface of the lens barrel 44 Cooperating with the internal thread on the lens holder 42 to convert the rotation of the lens holder 42 into the axial movement of the lens barrel 44, the lens barrel 44 will move away from the image sensor 5, at this time, the lens module 4 can be Focusing the near scene on the image sensor 5 is suitable for close-up. The photographer can preview the view by the internal screen 24.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
