Description

A protective case for photographing equipment with a detachable external camera

technical field

The utility model relates to the technical field of mobile phone accessories, in particular to a protective shell of a photographing device with a detachable external camera.

Background technique

When the mobile phone first appeared, it was only used as a portable phone terminal that could be used in a wide range. With the advancement of science and technology and the development of economy, the functions of mobile phones have become more and more powerful and have become a necessity of life. At present, mobile phones are divided into smart phones and non-smart phones. Due to the high frequency of smart phones, fast running speed, faster processing tasks, and more convenient daily life, smart phones now have a higher market share. Smartphone refers to a personal computer, with an independent operating system and an independent operating space. Users can install programs provided by third-party service providers such as software, games, and navigation by themselves, and can realize wireless network connection through mobile communication networks. The general term for the type of mobile phone.

One of the most basic functions of smartphones is the shooting function. Nowadays, the camera functions of mobile phones are getting more and more powerful and the pixels are getting higher and higher. However, the camera function integrated on the mobile phone is limited by the size and weight of the mobile phone during the design, and generally only simple shooting can be performed. However, this traditional fixed-focus mobile phone lens can no longer satisfy people's pursuit of higher quality of life, so there is an external camera for mobile phones. People can choose the special lens they need according to their shooting needs. Generally, special lenses include 2X zoom, 4X Zoom, Macro, Fisheye, Wide Angle, etc.

There are many ways to fix the external camera of the existing mobile phone to the mobile phone, most of which use a rotary positioning structure, and the external camera is rotated and positioned on the mobile phone case. However, its positioning structure is complex, which not only has high cost, but also reduces the user experience of consumers. Often due to the damage of the lens rotation positioning structure, the external camera and the built-in camera of the mobile phone cannot be accurately positioned, resulting in the entire external camera equipment cannot be used normally, resulting in Waste of resources.

For example, Chinese patent document CN204465641U discloses a multi-lens turntable mobile phone case, wherein a turntable is arranged on the mobile phone case and several lenses are arranged on the turntable, thereby realizing that the lens can be switched by rotating the turntable when using the mobile phone case. operation. The connection method of the turntable on the mobile phone case is as follows: the turntable is provided with irregular grooves on the side close to the mobile phone case shell, and a group of circular arc grooves are formed on the edge of the groove. Quantity corresponds to location. A telescopic positioning rod is fixed on the fixing hole on the side of the mobile phone case close to the turntable, the length of the telescopic rod is smaller than that of the casing, and the spring is arranged between the bottom of the telescopic rod and the inner surface of the bottom of the casing.

However, in the above patent, when the turntable is rotated, the main body of the telescopic positioning rod does not move, but still has to bear the rotational torque generated when the turntable rotates. Therefore, often after a period of use, the telescopic positioning rod begins to loosen, resulting in unsmooth rotation and failure of normal positioning.
