Abstract

The invention relates to a pen cap with a touch screen, which comprises a barrel-shaped pen cap body, an inner metal layer is arranged on the inner wall of the pen cap body, an outer metal layer is arranged on the outer wall of the pen cap body, and the end of the pen cap body is provided with a A pen cap made of conductive material. In the present invention, by setting the inner and outer metal layers on the pen cap body, a tiny capacitor is formed between the two metal layers. Assuming that the human body is an infinite zero potential field, after the human body touches the pen cap, the charge on the capacitor flows into the human body, making the Its potential is also zero. After the pen cap touches the capacitive screen, it will actively absorb the tiny current on the screen to charge the capacitor, which will be sensed by the capacitive screen to achieve the touch screen effect.

Description

touch screen pen cover

technical field

The invention relates to the field of office stationery, in particular to a touch screen pen cover.

Background technique

A pen is generally made up of a pen body and a pen cap. The stationery pens currently used for writing have a single function and can only be used for writing. Touch-screen electronic products are more and more widely used in all walks of life. At present, fingers are mainly used for touch-screen operation. However, in the actual operation process, there are often problems that fingers are not suitable for direct touch-screen operation and touch-screen operation is not sensitive. At this time, other parts that can realize touch screen operation are needed to replace fingers, and the pen is the most widely used tool in life, so it is necessary to improve the traditional pen so that it can be used for touch screen operate.

Contents of the invention

The purpose of the present invention is to provide a touch screen pen cover, which can be used for touch screen operation of electronic products.

To achieve the above object, the present invention adopts the following technical solutions:

A pen cap with a touch screen, characterized in that: it includes a barrel-shaped pen cap body, an inner metal layer is arranged on the inner wall of the pen cap body, an outer metal layer is arranged on the outer wall of the pen cap body, and the end of the pen cap body is arranged There are pen caps made of conductive material.

Further options are:

The pen cap head and the pen cap body are detachably connected and matched.

The curvature of the cap head can be adjusted according to different needs.

The pen cap is made of conductive silicone or conductive rubber.

The inner metal layer and the outer metal layer are electroplated metal layers.

The material composition of the inner metal layer and the outer metal layer is one or more of Cu, Ag, Fe.

A decorative layer is also provided on the outer side of the outer metal layer.

The end of the cap body is provided with a threaded hole, and the cap head is provided with a threaded segment, and the cap head and the cap body form a detachable connection through the threaded hole and the threaded segment.

The bottom of the inner cavity of the pen cover body is provided with a nib pad; the inner cavity wall of the pen cover body is provided with a card slot.

The thickness of the outer metal layer is greater than the thickness of the inner metal layer.

In the present invention, by setting the inner and outer metal layers on the pen cap body, a tiny capacitor is formed between the two metal layers. Assuming that the human body is an infinite zero potential field, after the human body touches the pen cap, the charge on the capacitor flows into the human body, making the Its potential is also zero. After the pen cap touches the capacitive screen, it will actively absorb the tiny current on the screen to charge the capacitor, which will be sensed by the capacitive screen to achieve the touch screen effect.

detailed description

In order to make the objects and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with examples. It should be understood that the following words are only used to describe one or several specific implementation modes of the present invention, and do not strictly limit the protection scope of the specific claims of the present invention.

The technical scheme adopted by the present invention is shown in Fig. 1, a kind of touch screen pen cover, comprises the pen cap body 10 of bucket cavity shape, the inner metal layer is arranged on the inner wall surface of pen cap body 10, on the outer wall of pen cap body 10 The outer metal layer is provided, and the end of the cap body 10 is provided with a cap tip 20 made of conductive material. In the present invention, the inner and outer metal layers are arranged on the pen cap body 10 to form a tiny capacitor between the two metal layers. Assuming that the human body is an infinite zero potential field, after the human body touches the pen cap, the charges on the capacitor flow into the human body. The electric potential is also zero, and after the pen cap 20 touches the capacitive screen, it will actively absorb the tiny current on the screen to charge the capacitor, which is sensed by the capacitive screen to achieve the effect of touching the screen.

A further solution is: the cap head 20 and the cap body 10 are detachably connected and matched; the cap head 20 is hemispherical. The curvature of the pen cap head 20 can be adjusted according to the usage habits and needs of different people, but the threaded section 21 should have a uniform specification, so as to replace the nib head and make unified production. The material of the pen cap 20 is selected from safe, soft and conductive materials, such as conductive silica gel, conductive rubber or the like.

The materials of the two metal coatings can be selected from Cu, Ag, Fe and other materials according to different market demands. The distance between the two metal plating layers, the thickness of the plating and the length of the pen cover can be adaptively adjusted according to the capacitance value required by the sensitive touch screen. The two metal plating layers are separated by the pen cap body 10 made of ordinary hard plastic, thereby forming a miniature capacitor. The outermost layer of the pen cap body 10 can be painted with different colors and decorative layers with patterns to make it compatible with the pen body.

The end of the cap body 10 is provided with a threaded hole 13 , and the cap head 20 is provided with a threaded section 21 . A nib pad 12 is provided at the bottom of the inner chamber of the cap body 10 . A card slot 11 is provided on the inner cavity wall of the pen cap body 10 . During specific operation, the nozzle diameter, thickness, and position of the draw-in groove 11 of the cap body 10 can be adjusted adaptively according to different types of pens. The cap head 20 is a knob type, which is convenient for disassembly and replacement; Metal plating is required to increase conductivity.

The above is only a preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, after knowing the content recorded in the present invention, they can also make changes to it without departing from the principle of the present invention. Several equivalent transformations and substitutions, such as applying this principle to the other end of the pen to make a dual-purpose pen capable of writing at one end and touching the screen at the other end, these equivalent transformations and substitutions should also be regarded as belonging to the protection scope of the present invention.
