Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
See also Fig. 1 and Fig. 2, the camera lens module 20 that the embodiment of the invention provides comprises filter plate switching device 10, lens barrel 12, is contained in the eyeglass (not shown) in this lens barrel 12.
This filter plate switching device 10 comprises the first stacked optical filtering portion 30, the second optical filtering portion 40 and the stationary shaft 50 that is arranged in this first optical filtering portion 30 and this second optical filtering portion 40.This filter plate switching device 10 is installed in the thing side of lens barrel 12, and in the present embodiment, this filter plate switching device 10 is installed in the outside end face of this lens barrel 12.Certainly, if desired, also the length of lens barrel 12 can be prolonged, with filter plate switching device 10 be installed in the lens barrel 12, before the eyeglass.
This first optical filtering portion 30 comprises first holding parts 31 and first optical filter 32.In the present embodiment, this first holding parts 31 is hollow ring, and it has one near first anchor ring 310 of thing side, and the central authorities of this first holding parts 31 are accommodated and be fixedly arranged on to this first optical filter 32.
This second optical filtering portion 40 comprises second holding parts 41 and second optical filter 42.In the present embodiment, this second holding parts 41 is hollow ring, and it has one near second anchor ring 410 of thing side, and the central authorities of this second holding parts 41 are accommodated and be fixedly arranged on to this second optical filter 42.
This second optical filtering portion 40 is than these first optical filtering portion, 30 more close thing sides.
This first optical filter 32 is different with the operation wavelength of this second optical filter 42.For example, this first optical filter 32 is infrared light optical filters, and it allows wavelength to pass through greater than the infrared light of 700nm, and this second optical filter 42 is visible filters, and it allows wavelength to pass through greater than 400nm and less than the visible light of 700nm.
The size of this first optical filter 32 and this second optical filter 42 at least will be greatly to the clear aperature that can cover this lens barrel 12.
The central shaft of this first holding parts 31 and this second holding parts 41 overlaps, preferably, and the central shaft of this first holding parts 31 and this second holding parts 41 and the central shaft of this lens barrel 12, that is optical axis coincidence.
The first optical filtering portion 30, the second optical filtering portion 40 all can carry out 360 degree around this stationary shaft 50 and rotate.
In the present embodiment, the external diameter of this first holding parts 31 and this second holding parts 41, internal diameter equate respectively.
Preferably, at first anchor ring 310 of this first holding parts 31 first rotation section 33 is set, at second anchor ring 410 of this second holding parts 41 second rotation section 43 is set.In the present embodiment, this first rotation section 33 and this second rotation section 43 all are the pole shape, and this second holding parts 41 is provided with breach to appear this first rotation section 33, makes things convenient for the user by rotating this first rotation section 33 and this second rotation section 43 this first optical filtering portion 30 of rotation and second optical filtering portions 40.
This first rotation section 33 can also be arranged on the side surface of first holding parts 31, and this second rotation section 43 also can be arranged on the side surface of second holding parts 41, in a word, is advisable with the rotation that does not influence this first optical filtering portion 30 and the second optical filtering portion 40.
See also Fig. 3 and Fig. 4, under original state, this first optical filtering portion 30 and this second optical filtering portion 40 are stacked and placed on the thing side of this lens barrel 12.In use, when needs use first optical filter 32, three-sixth turn is revolved away from light path around stationary shaft 50 in the second optical filtering portion 40, expose this first optical filtering portion 30.When needs use second optical filter 42, three-sixth turn is revolved away from light path around stationary shaft 50 in the first optical filtering portion 30, expose this second optical filtering portion 40.And, since fixing comparatively tight with this stationary shaft 50, no matter be that the first optical filtering portion 30 or the second optical filtering portion 40 all can keep static after revolving three-sixth turn therefore, can arbitrarily not swing.
Be appreciated that, if the external diameter of a holding parts is greater than the external diameter of another holding parts, for example, the external diameter of first holding parts 31 is greater than the external diameter of second holding parts 41, then the user also can easily manually rotate this first holding parts 31 or this second holding parts 41, at this moment, first rotation section 33 or second rotation section 43 just can arrange.
Be appreciated that, if use 20 pairs of operation wavelengths of camera lens module of this filter plate switching device 10 that further demand is arranged, for example, need certain coloured light, for example ruddiness, green glow or blue light equiwavelength's light is used for imaging, then can additionally increase corresponding ruddiness optical filter, green glow optical filter or blue filter etc., to satisfy diversified demand.
Because the filter plate switching device 10 that the embodiment of the invention provides places the first optical filtering portion 30 and the second optical filtering portion 40 the thing side of lens barrel 12, therefore the conversion that motor or Electromagnetic Drive structure are reached optical filtering portion needn't be set, only needing the first optical filtering portion 30 of manually rotating when needed or the second optical filtering portion 40 to be located in the light path gets final product, structure is small and exquisite, saves electric energy.The filter plate switching device 10 that the embodiment of the invention provides also can be applicable to the camera module, for example, picture side installing image sensor at lens barrel 12, again this filter plate switching device 10 is arranged at the thing side of lens barrel 12, be appreciated that, this filter plate switching device 10 both can be located at the inside of this lens barrel 12, also can be located at the outside of lens barrel 12.When filter plate switching device 10 is located at lens barrel 12 inside, can the rotation section be set at the side surface of each optical filtering portion, outside lens barrel 12, stir, change this optical filtering portion to make things convenient for the user.
