Description of the Invention: [Technical Field] The present invention relates to a mobile phone, and more particularly to a mobile phone with a digital camera. [Prior Art] At present, mobile phones with shooting functions are common in the market. The shooting function has become an important consideration for consumers when purchasing mobile phones. Manufacturers are also trying to develop products that cater to consumers' needs. Since the birth of the functional mobile phone, the resolution of the digital camera has increased from the initial 100,000 pixels to 300,000 pixels. Currently, the mobile phone with a 10,000-pixel digital camera has been put into the market, and has 200%. Mobile phones with 10,000 or even 3 megapixel digital cameras have also appeared on the market. However, due to the limitation of volume, the digital cameras on most mobile phones are fixed focal lengths, and the distance between the lens groups and between the lens group and the image sensor is constant, that is, the focal length £ and the image distance q are both The fixed value 'object distance p according to the optical formula l/p+l/q=l/f ' is also a fixed value. If the position of the shooting target exceeds the range of the object distance preset by the lens, the captured image will become blurred, thus greatly limiting the framing range β. For the above fixed focus lens, the solution for some digital cameras is to adopt An amplification interpolation method performs amplification on the digit § §, but only enlarges the original smaller area, and there is no new information increase, so the practicality is not large. Relatively speaking, from the principle of the lens, This problem can be solved by changing the focal length or image distance of the digital camera lens to a large extent. When the shooting target is out of the 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. Conventional digital camera focusing mechanism, which generally uses a common transmission device such as a DC motor or a stepping motor to drive the relevant optical components to perform a focusing operation, which is large in size and consumes a large amount of power, and is not suitable for assembly in a mobile phone; When the number of lenses of the relevant optical component is large, the transmission device also has certain difficulties in driving the optical component. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a mobile phone with a digital camera that can focus manually, improve image quality, and reduce the size and power consumption of a mobile phone. A mobile phone with a digital camera, comprising: an upper cover, comprising a sliding slot, the sliding slot is provided with a rack, a lower cover, comprising a slider and a receiving hole, the slider and the upper cover sliding The slot fits and slides in the 1363552 chute; and a digital camera module is disposed in the lower cover, the digital camera module includes a lens barrel and a support, and the lens barrel is screwed to the support, the mirror The sleeve is slidable in the receiving hole of the lower cover, and the support is provided with a gear which cooperates with the rack of the upper cover. Compared with the prior art, the mobile phone with the digital camera realizes the manual zoom function by sliding the top cover and the lower cover of the mobile phone, thereby avoiding the use of the electric component, thereby reducing the volume of the mobile phone: power consumption and cost.

It can only slide within the groove 242 and cannot rotate. The lens barrel 31 and the holder 32 are screwed. When the holder 32 rotates, the lens barrel 31 cannot rotate together, and it can only slide, that is, move back and forth with respect to the image sensor 33. Thus, the distance between the lens barrel 31 and the image sensor 33 is changed, thereby changing the image distance q to achieve the zoom function. When the upper cover 1 is slid to a different position, the image distance q is different, and the photographic view of the transparent body 25 of the lower cover 2 gives a photograph of a better quality. It can be understood that the hole 22 is not formed on the slider 22 of the lower cover 2, and the digital camera module 3 can also be inserted into the slider 22 to separate the slider 22 from the through hole 23. The image sensor 33 can also be The diameter of the tooth tip circle of the gear 322 fixed to the support 32 in the holder 32 is larger than the diameter of the through hole 23 of the front cover 2a. During assembly, the digital camera module 3 is inserted into the receiving hole 241 of the rear cover 2b through the through hole 23 of the front cover 2a from the side of the lens barrel 31, and the bump 312 is embedded in the recess 242, and then the front portion The cover 2a is snap-fitted to the rear cover 2b. Finally, the slider 22 is snapped into the sliding slot 13 of the upper cover 1, and the gear 322 is engaged with the rack 133 of the sliding slot 13. At this time, the gear 322 is limited by the bottom surface 131 of the sliding cover 13 of the upper cover 1 and is only rotatable. It is understood that the housing portion 24' of the digital camera with the lens holder 31 and the support 32 are not limited to hollow. The cylindrical body may have other shapes; the receiving hole 241 is not limited to a circular shape, and may have other shapes. 8 363 363552 : It is understood that the outer diameter of the smaller end of the support 32 is not limited to be smaller than the diameter of the receiving hole 24 下 of the lower cover 2, that is, the β support 32 may not be inserted into the receiving hole 24 , only the lens barrel 31 The bump 3丨2 can slide in the recess 242 of the lower cover 2. It is to be understood that the number of the bumps 3丨2 is not limited to one, and may be two or more.
