Description

Camera protection device and mobile terminal with the device

technical field

The utility model relates to electronic products, more specifically, to a camera protection device and a mobile terminal with a sliding cover of the camera lens protection device.

Background technique

With the improvement of people's living standards and the advancement of technology, the use of electronic products is very popular. Generally speaking, electronic products are often designed with a detachable cover to facilitate users to replace internal batteries, SIM cards and SD cards and other devices. The detachable cover of the product is divided into sliding type and retractable type. Let's take a mobile phone as an example to explain what is a sliding type and what is a retractable type. As shown in Figure 1, the so-called sliding type refers to the structure in which the cover plate 2 moves in parallel in one direction under the action of thrust (shown by the arrow in the figure) so as to break away from its limit clamp structure, and slide off the mobile phone body 1. It has the advantage of obvious opening feel. As shown in Figure 2, the so-called pull-out type refers to the fact that the bottom of the cover plate 2 is gradually opened from one side to the other side under the action of traction (as shown by the arrow in the figure), and the internal limit hooks are separated one by one. The structure is separated from the mobile phone body 1 in the way of opening, and the opening feel is poor.

Because of the good feel of the sliding type, it is used more and more. On the other hand, current electronic products basically have cameras, such as mobile phones, PDAs, tablet computers, point readers, electronic paper books, etc., and are limited by the needs of appearance and installation location, and the structures of these electronic products are very compact. , Small size, which limits the installation location of the camera. For a slide-open electronic product, especially an electronic product with a slide-open cover, often the position of the camera is within the range of the slide-open cover. As shown in Figure 3, the slide-open cover plate 2 is the battery cover structure most used in the structural design of the mobile phone 1. Because of the design requirements of the appearance, the cover plate often includes the protective lens 3' of the camera.

In this case, there are mainly two ways to protect the camera. Still taking the mobile phone as an example, the first method is to fix the camera and the protective lens of the camera separately, the lens 3' of the camera is fixed on the cover plate 2, and the camera 3 is fixed on the body of the mobile phone 1, as shown in Figure 4; The second is to fix the camera 3 and the protective lens of the camera lens on the body of the mobile phone 1, as shown in FIG. 5 .

The above-mentioned two installation methods of the camera and its lens in the related art have defects: in the case of the first method, the lens of the camera is fixed on the cover plate, and the appearance of the entire product can have a relatively rich form of expression, which can achieve appearance design. However, after the cover is disassembled, the camera is directly exposed, and there is a problem that the camera is scratched and dust enters, which affects the shooting quality; in the second case, although the camera and the lens of the camera are fixed together, the cover is removed. After opening, the lens still protects the camera, but the cover must have a gap at the position of the camera, which affects the aesthetics of the entire product.

As mentioned above, for electronic products, since the feel of the sliding type is better than that of the retractable type, the structural design first considers the sliding type. However, it is very important to solve the problem that the appearance of the slide-open type and the dust and scratch resistance of the camera cannot be taken into account, especially for high-end products, which have particularly high requirements for these two problems.
