Description

Touch control pen Technical Field The application relates to the technical field of electronic equipment, in particular to a touch pen. Background At present, most of touch pens can be applied to capacitive pens on a touch screen, the capacitive pens comprise electrodes and pressure sensing devices which are integrated together, the capacitive pens have high requirements on the screen, and application scenes are limited. In addition, pressure sensing device and camera device in the partial stylus are separately set up, need occupy the great space in the stylus, lead to the whole volume of stylus great, and camera device sets up in the position of skew stylus axis generally, this causes easily to cause the shielding of great area to camera device when holding the pen, is difficult to realize holding the pen at random, use experience is not good. Disclosure of Invention In view of the above, the present application provides a stylus to solve the problems of the prior art that the application scenario of the stylus is limited, and the volume of the stylus is large and the shielding area of the camera is large due to the separate arrangement of the pressure sensing device and the camera in the stylus. The embodiment of the application provides a touch pen, which comprises a shell component, a pen point, a camera device and a pressure sensing component, wherein at least part of the camera device is connected with the pen point and used for synchronously moving with the pen point relative to the shell component. At least part of the pressure sensing component is connected with the camera device and used for detecting the pressure born by the pen point. The camera device is used for acquiring an environment image around the pen point, and the environment image is used for determining the position of the pen point. The position of the pen tip may be a position where the pen tip contacts the touch surface (such as a display screen), and it is understood that the contact position of the pen tip and the touch surface may be a region range, but may be converted into a point coordinate or a region coordinate for representing the position of the pen tip through calculation, or the position of the pen tip may also be a position of a designated marker on the pen tip. After the pen point position is determined, the pen point position can be used for various possible application scenes, for example, writing handwriting is correspondingly presented on the touch control surface according to the determined pen point position, or a display object on the touch control surface is controlled or effects are presented.
