Detailed ways

Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited by the exemplary embodiments described herein.

Application overview

As mentioned above, although the existing periscope camera module has realized the ability of long-range shooting to a certain extent, it still cannot well meet the requirements of the market. Moreover, compared with the conventional linear camera module, the periscope optical system design is more complicated, the structure design is more complicated, the assembly difficulty is higher, and the test process is more difficult. In some applications, the periscope camera module The team also needs to meet the anti-shake requirements, and these factors limit the development of periscope camera modules.

Chinese patent CN110398872A discloses a lens module and camera, wherein the optical system of the lens module (the lens module is a periscope camera module) includes a first refraction element, a second refraction element, a reflection element, and a photosensitive element. Element, wherein the first refractive element and the reflective element are arranged along the direction of the first optical axis, the second refractive element and the reflective element are arranged along the direction of the second optical axis, the first optical axis is the optical axis of the first refractive element, and the The second optical axis is the optical axis of the second refraction element, and the first optical axis is perpendicular to the second optical axis, and the second refraction element is arranged parallel to the photosensitive element. In the height direction of the lens module, the first refraction element The effective aperture is larger than the effective aperture of the second refraction element, the first optical axis is parallel to the height direction of the lens module, and the second optical axis is perpendicular to the height direction of the lens module. According to the content in the background part and the content of the invention, the lens module is easier to take the effect of large aperture through the above-mentioned optical system, that is, the design scheme of the optical system adopted by the lens module can increase its aperture. However, this optical system design has some problems in the structure of the optical system and the adjustment of the optical system.

Specifically, in order to increase the aperture, the optical system is equipped with refraction elements above and to the right of the first reflection element, namely, the first refraction element and the second refraction element. This design solution is structurally difficult to implement. The main reasons include: in order to ensure that the technical purpose of increasing the aperture can be achieved, in the specific process of building the optical system, the assembly accuracy of the first refraction element, the reflection element, and the second refraction element is required to be very high. However, in this optical system design, the first refraction element, the reflection element, and the second refraction element are not arranged in a straight line but are arranged in a right angle in space. This requires the assembly of the first refraction element, the reflection element, and the second refraction element. The second refraction element needs to consider more dimensions of position accuracy (including the inclination angle of the first refraction element, the reflection element, the second refraction element itself, the relative positional relationship between the first refraction element and the reflection element, and the second refraction element The relative positional relationship between the element and the reflective element). Even if the construction accuracy of its optical system can meet the preset requirements through some structural design schemes and high-end assembly processes, the relatively complex design of its optical system leads to its relatively low stability. For example, during use, if If the first refraction element or the second refraction element shakes, the performance of the optical system will be significantly affected.

Moreover, the optical system design solution is not conducive to the adjustment of the optical system, such as optical anti-shake, automatic focusing, etc. The main reasons include: in the optical system design solution, the distribution of optical elements used to adjust the optical performance is scattered. For example, in an optical anti-shake design solution, optical anti-shake is performed by adjusting the first refraction element and the second refraction element. Since the first refraction element and the second refraction element are distributed on both sides of the reflection element, therefore, It is necessary to configure anti-shake motors for the first refraction element and the second refraction element respectively to achieve the effect of optical anti-shake, and it should be understood that this kind of optical anti-shake design scheme requires two anti-shake motors to cooperate with each other, which is more difficult .

Chinese patent CN110879454A discloses a camera module, a periscope camera module, a camera assembly, and an electronic device. The camera module includes a fixing part, a lens assembly, an image sensor, and a focusing assembly. The image sensor is used for To receive light passing through the lens assembly. In the focusing assembly, the first light turning member is used to turn the light that is transmitted from the lens assembly to the image sensor; the second light turning member is used to turn the light that is turned by the first light turning member, and is It is configured to be movable relative to the fixed part to change the distance from the lens assembly to the image sensor. According to the disclosed part, it can be known that the distance between the first light turning member and the second light turning member can be adjusted to adjust the distance of the light propagation path between the lens assembly and the image sensor, and the focusing of the lens assembly is completed. , The imaging of the image sensor is realized, and the length of the camera module in the optical axis direction of the lens assembly is shortened.

However, the optical system design solution performs poorly in some important optical characteristics, especially the aperture size, and the light input of the optical system may be insufficient, which may affect the imaging performance of the camera module. In addition, the design of the optical system is not particularly friendly to the structure of the optical system. The main reason is that: in the construction of the optical system, all the optical elements and adjustment mechanisms are installed in a carrier, that is, the fixing part, the Those of ordinary skill in the art should be aware that this assembly method is prone to accumulation of errors during the assembly process, resulting in low assembly accuracy of the final product.

In the optical system design of the periscope camera module, it is not only necessary to consider the optical performance (for example, aperture size, effective focal length, etc.) that the optical system can achieve, but also to consider the optical system design in the optical system construction The difficulty of the aspect and the ease of adjustment of the optical system. Here, it should be understood that the construction of the optical system refers to the construction of the optical system design plan through the structural design plan, and the adjustment of the optical system refers to the need to adjust the position of certain optical elements to achieve changes in optical performance.

In view of the above-mentioned technical ideas and current research and development status, the basic idea of this application is to adopt a specific optical system design, so that the optical system can obtain the optical performance, the difficulty of optical system construction, and the difficulty of optical system adjustment. Better overall performance.

Based on this, the present application proposes a photosensitive component, which includes: an optical lens for receiving imaging light from the outside to form a first light beam with a first optical axis; and a first light-reflecting element corresponding to the optical lens , For turning the first light beam to form a second light beam with a second optical axis, the second optical axis being perpendicular to the first optical axis; corresponding to the second light turning element A light turning element for turning the second light beam to form a third optical path with a third optical axis, the third optical axis being perpendicular to the set by the first optical axis and the second optical axis A fixed plane; a third light-reflecting element corresponding to the second light-reflecting element, for turning the third light beam to form a fourth light beam having a fourth optical axis, the fourth optical axis being perpendicular to The third optical axis; and a photosensitive chip for receiving the fourth light beam. In this way, a specific optical system design is adopted so that the optical system can achieve better overall performance in terms of optical performance, difficulty in constructing the optical system, and difficulty in adjusting the optical system.

After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail below with reference to the accompanying drawings.
