Abstract
A lens module comprises a lens barrel and a plurality of lenses arranged in the lens barrel, wherein a side wall-penetrating light inlet hole used for incident light to enter is formed on the side wall of the lens barrel; and the plurality of lenses comprises a refraction lens, wherein the refraction lens comprises a light collecting surface, a light extraction surface and a total reflection light extraction surface, the light collecting surface is opposite to the light inlet hole, the light extraction surface is opposite to an end of the lens barrel away from the light inlet hole, and all the incident light on the light collection surface is reflected onto the light extraction surface through the total reflection surface. As the light inlet hole is formed on the side wall of the lens barrel, and the incident light is deflected through the refraction lens, the lens module is more suitable for being arranged in an imaging device in a manner parallel to an object side surface of the imaging device in the length direction. Therefore, the overall thickness of the imaging device can be further reduced.
Description
Technical field
The present invention relates to a kind of camera lens module and have the imaging device of this camera lens module.
Background technology
Nowadays, the miniaturization of imaging device, slimming have become a kind of trend.A kind of means of imaging device slimming are to shorten the length of camera lens module, and then the general thickness of shortening imaging device is to reach purpose of thinness.And optical elements such as the interior eyeglass of existing camera lens module all are to arrange along the axis of lens barrel, and light arrives imaging surface from an end of described lens barrel along each optical element that straight line passes in the described lens barrel successively.For reaching purposes such as zoom and assurance image quality, need to keep certain spacing between each optical element, therefore the overall length of lens barrel can only foreshorten to a certain degree, and therefore the mode of optical tube length is shortened in simple dependence, and the general thickness of imaging device still is difficult to satisfactory.
Summary of the invention
In view of this, be necessary to provide the camera lens module of the general thickness that is suitable for reducing imaging device and the imaging device with this camera lens module.
A kind of camera lens module, it comprises a lens barrel and is arranged at the interior a plurality of eyeglasses of described lens barrel.The sidewall of described lens barrel offers an incidence hole that is used for entering and running through for incident light this sidewall.Described a plurality of eyeglass comprises a refractive power eyeglass.Described refractive power eyeglass comprises that is advanced a light face, and an exiting surface and a fully reflecting surface describedly advance the light face over against described incidence hole, and described exiting surface is over against the end of described lens barrel away from described incidence hole.Described fully reflecting surface is used for will be through described incident light total reflection of advancing the light face described exiting surface extremely.Described lens barrel comprises the picture side that a thing side and and described thing side are opposing, and described incidence hole is near the thing side of described lens barrel.The inside surface of described lens barrel forms a step, and described step is positioned at described incidence hole near a side of described picture side, describedly advances between light face and the described exiting surface to be formed with one corresponding to the groove of described step, and described step is resisted against in the described groove.
A kind of imaging device, it comprises an above-mentioned camera lens module, described imaging device has a thing side surface.Described camera lens module is arranged in the described imaging device in the length direction of the described camera lens module mode parallel with described thing side surface.
Because the camera lens module is by offering incidence hole at its lens barrel sidewall, simultaneously by described refractive power eyeglass with the incident light deviation, so described camera lens module more be applicable to the length direction mode parallel with described thing side surface arrange with described imaging device in.Therefore, the general thickness of described imaging device can further reduce.

Embodiment
Below in conjunction with accompanying drawing the present invention being done one specifically introduces.
See also Fig. 1, be depicted as the structural drawing of camera lens module 100 of the present invention, described camera lens module 100 comprises a lens barrel 10 and a plurality of eyeglass 20 that has positive and negative focal power in the described lens barrel 10 respectively that is arranged at.
Described lens barrel 10 comprises the picture side 12 that a thing side 11 and and described thing side 11 are opposing.Offer an incidence hole that runs through 101 near described thing side 11 on the sidewall of described lens barrel 10, the inside surface of described lens barrel 10 forms a step 13, and described step 13 is positioned at described incidence hole 101 near a side of described picture side 12.
Described eyeglass 20 comprises a refractive power eyeglass 21.Described refractive power eyeglass 21 comprises that one is advanced 211, one exiting surfaces 212 of light face and a fully reflecting surface 213.Describedly advance light face 211 and be curved surface with described exiting surface 212, described fully reflecting surface 213 is the plane, and the perpendicular bisector of the described perpendicular bisector that advances light face 211 and described exiting surface 212 is orthogonal and be miter angle with described fully reflecting surface 213 respectively.Describedly advance between light face 211 and the described exiting surface 212 to be formed with one corresponding to the groove 214 of described step 13.Described refractive power eyeglass 21 is from the thing side 11 of the described lens barrel 10 described lens barrel 10 of packing into, and the step 13 of described lens barrel 10 is resisted against in the described groove 214, describedly advances light face 211 over against described incidence hole 101, and described exiting surface 212 is over against the picture side 12 of described lens barrel 10.In the present embodiment, describedly advance light face 211 and described exiting surface 212 is aspheric convex surface, therefore described refractive power eyeglass 21 has positive light coke.
Described eyeglass 20 also comprises 22, one second eyeglasses 23 of first eyeglass and a prismatic glasses 24.Described first eyeglass 22, second eyeglass 23 and prismatic glasses 24 are from exiting surface 212 being arranged in order as side 12 to described lens barrel 10 of described refractive power eyeglass 21.First eyeglass 22 has negative power described in the present embodiment, and described second eyeglass 23 has positive light coke, and described prismatic glasses 24 has negative power.Certainly, the quantity of the eyeglass that comprises in the described lens barrel 10 and shape are not limited to the description in the present embodiment, can do other variation according to different standards.
The thing side sealing of the lens barrel 10 of the camera lens module 100 after assembling is finished.During work, light in described incidence hole 101 enters described lens barrel 10 enocscope sheet 21 advance light face 211, total reflection through described fully reflecting surface 213 is penetrated from described exiting surface 212, passes the imaging surface of described first eyeglass 22, described second eyeglass 23, described prismatic glasses 24 arrival image sensor (not shown) successively.
See also Fig. 2, be depicted as the synoptic diagram of a kind of imaging device 200 with camera lens module 100 of the present invention.Described imaging device 200 comprises when taking a thing side surface 201 towards subject.Because camera lens module 100 is by offering incidence hole 101 at its lens barrel 10 sidewalls, simultaneously by described refractive power eyeglass (not shown) with the incident light deviation, therefore described camera lens module 100 more be applicable to its length direction and described thing side surface 201 parallel modes arrange with described imaging device 200 in.Therefore, the general thickness of described imaging device 200 can further reduce.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
