Description

Folding-type electronic device with digital camera

[technical field]

The invention relates to a kind of folding-type electronic device, especially a kind of folding-type electronic device with digital camera.

[background technology]

Development along with the radio communication and the information processing technology, mobile phone, PDA (PersonalDigital Assistant, the personal digital assistant) etc. the application of electronic installation is more prevalent, and the product that increases additional function on electronic installation competitively emerges in large numbers, and for example has the electronic installation of digital camera.

The mobile phone of tool shoot function is since being born, the resolution of the digital camera on it develops into 300,000 pixels from 100,000 initial pixels, the mobile phone that has 1,000,000 pixel digital cameras at present also puts goods on the market, and the mobile phone with 2,000,000 even 3,000,000 pixel digital cameras also occurs on market.Yet, because volume limits, digital camera on present most of mobile phone is fixed focal length, between the lens set and the distance between lens set and the image sensor be definite value, be that focal distance f and image distance q all are definite values, according to optics formula 1/p+1/q=1/f, the object distance p of photographic subjects also is a definite value.If the photographic subjects present position exceeds the default object distance scope of camera lens, take the gained image so and will thicken unclearly, therefore limited viewfinder range greatly.

Deficiency at the said fixing focal length lens, the solution of part digital camera is to adopt a kind of amplification interpolation method that digital signal is done processing and amplifying, still, so only makes originally and amplifies than the zonule, not having new information increases, so practicality is little.

Comparatively speaking, from the principle of lens, then can address this problem to a great extent by focal length or the image distance that changes digital camera lens.When photographic subjects exceeds set object distance scope, obtain a new object distance that is suitable for this target by changing focal length or image distance, thereby can guarantee image quality.

[summary of the invention]

In view of above content, be necessary to provide a kind of folding-type electronic device with digital camera with focus function.

A kind of folding-type electronic device with digital camera, it comprises body, lid, hinge and camera lens module, this body is connected by this hinge through with this lid, this camera lens module comprises set of lenses, lens barrel and lens mount, this entirety of lens package is assigned in this lens barrel, this lens barrel is assemblied in this lens mount by threaded engagement, this folding-type electronic device with digital camera further comprise be located in this body and with the corresponding image sensor of camera lens module; Be provided with groove with a hinged end on this lid, the groove opposite position with lid on this body is provided with an opening, is provided with a bearing in order to the support lens module in this body, is provided with a through hole in this bearing, and this through-hole wall is offered a groove; This camera lens module is located in this body, this lens mount one end is provided with gear, this gear reveals by this opening, and match with the groove on the lid, this lens barrel is provided with a protuberance, groove fit on this protuberance and the body when the rotation of the relative body of lid, is converted into moving axially of the relative image sensor of lens barrel with the rotation of lens mount.

Compare prior art, described folding-type electronic device with digital camera rotates this lid, rotate by driving groove and cooperating of gear this lens mount, realize focusing, clear the focusing on the imaging surface of object that can distance is different when taking pictures improved image quality.

[embodiment]

Preferred embodiment of the present invention discloses a kind of folding-type electronic device with digital camera, and it can be mobile phone, PDA etc., and present embodiment is that example describes with the mobile phone.

Please in conjunction with consulting Fig. 1, Fig. 2 and Fig. 3, the mobile phone with digital camera of this preferred embodiment comprises body 1, lid 2, hinge 3, camera lens module 4 and image sensor 5.Body 1 is rotationally connected by hinge 3 with lid 2.

Body 1 comprises first housing 11 and second housing, 12, the first housings 11 and second housing 12 engaging formation one accommodation space mutually, is used to accommodate printed circuit board (PCB) (figure does not show).Body 1 is provided with keyboard 13.On first housing 11, an end that is connected with hinge 3 is provided with an opening 112.Offer a hole 121 on second housing, 12 sidewalls, camera lens module 4 reveals by hole 121.Be provided with a bearing 122 in second housing 12, be used for support lens module 4.One through hole 124 is opened on the bearing 122, and corresponding with hole 121 and connect.Be provided with a groove 126 in the through hole 124.

Lid 2 comprise housing 21, outward shield 22 and in the screen 24.Outer screen 22 is located at the outer surface of lid 2, and interior screen 24 is located at the inner surface of lid 2, and wherein, outer surface is meant the surface that exposes outside when lid 2 is closed with respect to body 1, and inner surface is meant when lid 2 during with respect to body 1 closure, with body 1 contacted surface.On the housing 21, an end that is connected with hinge 3 is provided with groove 212.

Please in conjunction with consulting Fig. 3 and Fig. 4, camera lens module 4 comprises set of lenses 41, lens barrel 44 and lens mount 42.Set of lenses 41 is assemblied in the lens barrel 44.Lens barrel 44 outer surfaces are provided with external screw thread 441, and lens mount 42 inner surfaces are provided with internal thread 421, and by the cooperation of screw thread, lens barrel 44 is assemblied in the lens mount 42, and can be with respect to lens mount 42 spinning in and out.Lens barrel 44 sides are provided with a protuberance 442.Lens mount 42 is provided with the gear 422 that can match with the groove 212 on the lid 2 away from the outer surface of lens barrel 44 1 ends.When camera lens module 4 was installed on the body 1, lens barrel 44 was installed in the through hole 124, and the protuberance on the lens barrel 44 442 is slidingly matched with recess 126 on the bearing 122, and lens mount 42 parts are contained in the through hole 124, and gear 422 is exposed to outside the through hole 124.Gear 422 112 reveals by opening on first housing 11, matches with groove 212 on the lid 2.
