The optical zoom apparatus that the utility model embodiment provides, it increases reflex reflector lens between focus-variable lens group and the light of incident, the reflection of the light by reflex reflector lens to incident changes the transmission direction of the light of incident, and on the path of the light of reflex reflector lens reflection incident, focus-variable lens group is set, thereby change the orientation of focus-variable lens group and imageing sensor, thereby while making camera use this optical zoom apparatus, focus-variable lens group and imageing sensor are no longer arranged along the thickness direction of mobile phone or panel computer, can not make the thickness of mobile phone or panel computer increase.
Brief description of the drawings
Fig. 1 shows the structural representation of a kind of embodiment of the optical zoom apparatus in background technology;
Fig. 2 shows the structural representation of a kind of embodiment of optical zoom apparatus of the present utility model;
Fig. 3 shows the structural representation of the another kind of embodiment of optical zoom apparatus of the present utility model.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Optical zoom apparatus, as shown in Figures 2 and 3, comprising: focus-variable lens group 201 and imageing sensor 202; Also comprise reflex reflector lens 203; Reflex reflector lens receives the light of incident and is reflexed to focus-variable lens group; Focus-variable lens group receives the light of reflex reflector lens reflection and is transmitted through imageing sensor.
Wherein, focus-variable lens group can be manual focus-variable lens group or power zoom lens set; Manually the conversion between focus-variable lens group and power zoom lens set can realize by switch.Distance between reflex reflector lens and phone housing, and distance between focus-variable lens group and reflex reflector lens can be set or adjust according to the thickness of mobile phone or panel computer.Because the incident angle of reflex reflector lens equates with reflection angle, therefore can be according to focus-variable lens group in mobile phone or panel computer orientation determination reflection angle be set, thereby determine the incident angle of reflex reflector lens, thereby determine the angle between reflex reflector lens and the shell of mobile phone or panel computer.
The optical zoom apparatus that the utility model embodiment provides, it increases reflex reflector lens between focus-variable lens group and the light of incident, the reflection of the light by reflex reflector lens to incident changes the transmission direction of the light of incident, and on the path of the light of reflex reflector lens reflection incident, focus-variable lens group is set, thereby change the orientation of focus-variable lens group and imageing sensor, thereby while making camera use this optical zoom apparatus, focus-variable lens group and imageing sensor are no longer arranged along the thickness direction of mobile phone or panel computer, can not make the thickness of mobile phone or panel computer increase.
Preferably, in the embodiment of above-mentioned optical zoom apparatus, the angle of the light of reflex reflector lens and incident is 45 °.
Wherein, the angle of the light of reflex reflector lens and incident is 45 °, be also reflex reflector lens with the shell of mobile phone or panel computer because reflex reflector lens incident angle equates with reflection angle, so the angle of the light of reflex reflector lens and reflection is also 45 °.
Thereby the angle of the light by setting reflex reflector lens and incident is 45 °, more vertical with the shell of mobile phone or panel computer according to the light of incident, the position of reflex reflector lens and focus-variable lens group can be conveniently set according to phone housing.
Preferably, in the embodiment of above-mentioned optical zoom apparatus, as shown in Figure 3, can comprise: flat mirror 204; Flat mirror is located between reflex reflector lens and the light of incident, and the light of incident is transmitted through to reflex reflector lens.
