Described lid 2 has in 21, one of the outer screens and shields 22, holes 23 and receiver 24.Outer screen 21 is located at the outer surface of lid 2, and interior screen 22 is located at the inner surface of lid 2, is in the display screen of camera lens module 4 under closed and the open mode respectively as lid 2.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 is closed with respect to body 1, faces the surface of body 1.The outer surface of lid 2 is located in described hole 23, is used for the aperture as camera module 4.Described receiver 24 is located at the inner surface of lid 2.Described lid 2 is provided with an opening 25 near rotating shaft 3 places, and described crawler belt 5 can enter in the lid 2 by described opening 25.Be provided with a guiding mechanism 26 in the described lid 2, be used to control the direction of motion of crawler belt 5 in lid 2, make crawler belt 5 normally to cooperate with camera module 4.Described guiding mechanism 26 can be specially the structure with a pilot hole, thereby described crawler belt 5 passes the purpose that described pilot hole reaches control crawler belt 5 directions of motion.
Described rotating shaft 3 peripheries are provided with groove 31, can drive crawler belt 5 motions when lid 2 open and closes of folding-type electronic device 100.In the present embodiment, described rotating shaft 3 is structure as a whole with lid 2.
See also Fig. 2 and Fig. 4, in the present embodiment, described camera module 4 is located in the lid 2, and it is aimed at the hole 23 on the lid 2.Described camera module 4 comprises an outer cover 40 and is arranged at one first lens barrel 41 in the described outer cover 40, second lens barrel 42 and an image sensor 43.Described outer cover 40 comprises a back cover 40a and a front shroud 40b, and described back cover 40a and front shroud 40b are adhesively fixed mutually, and the shape of described outer cover 40 inboards and the outer shape of described second lens barrel 42 are complementary.One side of described outer cover 40 is provided with an opening 401.Described front shroud 40b is near hole 23, and has a light inlet 402 and aim at described hole 23.In the present embodiment, the inner surface of described back cover 40a is provided with two projections 403.The quantity that is appreciated that the projection 403 that the inner surface of described back cover 40a is provided with can be for one or more.
Described first lens barrel 41 is a hollow circular cylinder, be provided with set of lenses (figure does not show) in it, one end face of described first lens barrel 41 is offered a pair of breach 411, described breach 411 matches with the projection 403 of described outer cover 40a inner surface, described projection 403 can insert the lens barrel 41 of winning only can be moved on optical axis direction, described breach 411 has certain depth, corresponding projection 403 has certain length, can make first lens barrel 41 on its optical axis direction when mobile, described projection 403 can not skid off in breach 411.Described second lens barrel 42 is a hollow circular cylinder, and its internal diameter is greater than the external diameter of first lens barrel 41, and can rotate in outer cover 40.The arranged outside of the inboard of described second lens barrel 42 and described first lens barrel 41 has intermeshing screw thread 421 and screw thread 412.Described second lens barrel 42 is provided with focusing bar 422, protrude from described second lens barrel, 42 outer surfaces, described focusing bar 422 stretches out from the opening 401 of described outer cover 40, and its diameter equates substantially with the height of described opening 401 and closely cooperates, make described focusing bar 422 not move along optical axis direction, and can only rotate, thereby make described second lens barrel 42 only can rotate and can not move along optical axis direction along opening.Described image sensor 43 is fixed in the inner surface with described back cover 40a.Certainly, the outside of the inboard of described second lens barrel 42 and described first lens barrel 41 also can cooperate by cam structure.Described second lens barrel 42 and described first lens barrel 41 can also be designed to the situation of second lens barrel, 42 external diameters less than first lens barrel, 41 internal diameters, are not limited to present embodiment.In addition, described camera module 4 also can be located in the body of described folding-type electronic device 100, and the light inlet of described camera module 4 can be in the outer surface of lid 2, the outer surface of body 1, the side of lid 2 and the side of body 1.
In the present embodiment, have groove 51 on the described crawler belt 5, cooperate, thereby can when lid 2 open and closes, can be driven with groove 31 with rotating shaft 3 peripheries.In the present embodiment, described crawler belt 5 be provided with one vertical with crawler belt 5 directions of motion and be basically parallel to the collar 52 of lid 2 upper surfaces, focusing bar 422 on described second lens barrel 42 can insert the described collar 52, thereby when crawler belt 5 moves, by the focusing bar 422 transmission second lens barrel 42 is rotated in outer cover 40.Because second lens barrel 42 can not move along optical axis direction in rotation process, and first lens barrel 41 can not rotate owing to the projection 403 and the effect of breach 411, thereby make in the rotation process of second lens barrel 42, the screw thread 412 in the screw thread 421 of second lens barrel, 42 inboards and first lens barrel, 41 outsides interacts and first lens barrel 41 is moved along its optical axis direction, thereby first lens barrel 41 and the distance of image sensor 43 are changed, reach the purpose of focusing.Be appreciated that described crawler belt 5 is not limited to described in the present embodiment by the situation of a collar 52 is set with focusing cooperating of bar 422 on crawler belt 5.When the light inlet of camera module 4 is faced the side of lid 2, but the corresponding setting collar 52 makes that the collar 52 is vertical with crawler belt 5 directions of motion and is basically perpendicular to lid 2 upper surfaces.Described crawler belt 5 is made by the pliability material, and has certain rigid, makes crawler belt 5 to move along the pilot hole direction.
In addition, in other embodiments, described crawler belt 5 also can an end stretches in the lid 2 and cooperates with camera module 4, and the other end is fixed in the rotating shaft 3, but when lid 2 was in closure state, described crawler belt 5 should have certain length winding in rotating shaft 3.At this moment, described crawler belt 5 need have certain elasticity, can need not to be provided with groove etc. and rotating shaft 3 engagements on it.
See also Fig. 2, when folding-type electronic device 100 was in closure state, focusing bar 422 was away from a side of rotating shaft 3.See also Fig. 5, when folding-type electronic device 100 was opened, the parts that described rotating shaft 3 rotation drive crawler belts 5 are in the lid 2 moved to the direction near rotating shaft 3, thereby rotated by bar 422 drives second lens barrel 42 of focusing, and reached the effect of focusing.
Described folding-type electronic device adopts crawler belt to drive the rotation of camera module Focusing mechanism by the open and close operation of lid, realizes focusing, and clear the focusing on the imaging surface of object that can distance is different when taking pictures improved image quality.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection range that all should belong to claim of the present invention with distortion.
