Problems solved by technology

It can be seen that the thickness T1 of the existing periscope lens is limited by the width T2 of the sensor
[0004] Therefore, in the prior art, in order to improve the imaging quality, it is necessary to increase the width of the sensor of the periscope lens, so that the thickness of the periscope lens increases accordingly. also increased

Embodiment 1

[0038] figure 2 A structural diagram of a periscope lens according to an embodiment of the present invention is shown. like figure 2 As shown, the periscope lens may include: a filter 210, a reflective prism group 220, a zoom lens 230, and a sensor (sensor) 240;

[0039] Wherein, the optical filter 210 is used to filter light incident from the outside;

[0040] The reflective prism group 220 is used to combine with the zoom lens 230 to reflect the light filtered by the filter 210 twice and enter the sensor 240 .

[0041] Specifically, the light is filtered by the filter 210 of the periscope lens and then enters the reflective prism group 220 . After being reflected twice by the reflective prism group 220 , the light is optically zoomed by the zoom lens 230 , and finally enters the sensor 240 .

[0042] Wherein, the sensor 240 may be a photosensitive element, which may perform photoelectric conversion on incident light and output it to a terminal device for processing such...

Embodiment 2

[0046] image 3 A composition structure diagram of a periscope lens according to another embodiment of the present invention is shown. image 3 Winning mark and figure 2 The same components have the same functionality. like image 3 shown, with figure 2 Compared with the shown periscope lens, the main difference is that the reflective prism group 220 may also include at least: a first reflective prism 310 and a second reflective prism 320; wherein, the first reflective prism 310 is used to combine the The light emitted by the filter mirror 210 is reflected to the zoom mirror 230 ; the second reflective prism 320 is configured to reflect the light emitted by the zoom mirror 230 to the sensor 240 .

[0047]For the above-mentioned periscope lens, in a possible implementation manner, the filter 210 and the first reflective prism 310 can be placed at a first angle α, and the range of the first angle α can be 30 degrees ~60 degrees. Preferably, the first angle α may be 45 de...

Embodiment 3

[0053] Figure 4a A schematic cross-sectional view showing a composition structure of a terminal device according to yet another embodiment of the present invention. Figure 4b A schematic rear view showing the composition structure of a terminal device according to yet another embodiment of the present invention. like Figure 4a and Figure 4b As shown, the terminal device may include: a periscope lens 410 with any one of the above structures.

[0054] like Figure 4a and Figure 4b As shown, the terminal device in this embodiment may also include: a display screen 420, a battery 430, a PCBA (Printed Circuit Board Assembly, made into a board assembly) 440, a housing 450, a front camera (Camera) 460, a receiver (Receiver) 470 , xenon lamp 480 , SIM (Subscriber Identity Module, Subscriber Identity Module) card 490 and T card (T-flash card, removable flash memory card) 400 . Wherein, the type of the display screen 420 is not limited, and may be LCD (Liquid Crystal Display,...

Abstract

The invention discloses a periscopic lens and a terminal device. The periscopic lens comprises a glass filter, a reflection prism set, a zooming lens and a sensor, wherein the glass filter is used for filtering light rays irradiated from the external, and the reflection prism set is used for being combined with the zooming lens to enable the light rays filtered by the glass filter to be irradiated into the sensor after two times of reflection. According to the periscopic lens and the terminal device, the limitation of the width of the sensor to the thickness of the periscopic lens can be reduced, when the size of the periphery of the sensor is increased due to the fact that the larger-size sensor and the OIS anti-shake technology are used for improving the imaging quality, the thin periscopic lens can be guaranteed, the imaging quality of the periscopic lens with the same thickness size can also be improved, and the terminal device provided with the periscopic lens can have the high imaging quality and can be thin in thickness.

Description

technical field [0001] The present invention relates to an electronic device, in particular to a periscope lens and a terminal device. Background technique [0002] At present, the camera function is more and more widely used in mobile phones. Built-in periscope lenses with optical zoom capabilities are widely used on mobile phones. As users have higher performance requirements for mobile phones and digital cameras, such as higher optical zoom factor, higher image quality and other imaging quality, but the size of the photosensitive element (ie sensor) that can meet such high performance is correspondingly larger . [0003] figure 1 Schematic showing an existing periscope lens. like figure 1 As shown, the external light of the existing periscope lens is filtered by the lens module 110, reflected by the reflective prism module 120, optically zoomed by the intermediate zoom lens module 130, and imaged on the sensor placed at the bottom of the lens 140 on. It can be seen...
