Detailed Description

It should be noted that, without conflict, the embodiments and features of the embodiments in the present application may be combined with each other, and the present invention will be further described in detail with reference to the drawings and the specific embodiments.

In the embodiment of the present invention, if there is a directional indication (such as up, down, left, right, front, and rear … …) only for explaining the relative positional relationship, movement condition, etc. between the components in a specific posture (as shown in the drawings), if the specific posture is changed, the directional indication is correspondingly changed.

In addition, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implying an indication of the number of features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 6, an electronic pen based on a metal ball-point pen refill according to an embodiment of the present invention includes a barrel. A main support and a main board for receiving signals are arranged in the pen container.

The pen container is provided with a pen core cavity for inserting the metal ball-point pen core, and the metal ball-point pen core is arranged in the pen core cavity. The end of the pen refill cavity is provided with a spring fixing frame. The metal ball-point pen refill can be replaced.

The tail end of the spring fixing frame is provided with a contact spring which is connected with the main board and transmits signals. The contact spring conducts the metal ball-point pen refill with a circuit on the main board, so that signal transmission to the metal ball-point pen refill is realized. One end of the contact spring is propped against the spring fixing frame, and the other end is propped against the main support. The front end of the spring fixing frame is provided with a fixing part which is used for being connected and conducted with the metal ball pen core, and the fixing part is connected with the contact spring. The fixing part is a clip for clamping the inserted metal ball-point pen refill. In the concrete implementation, the fixing part is a part of a spring, the tail end of the spring fixing frame is convexly provided with a conical seat, and the spring is clamped on the conical seat of the spring fixing frame; the front end of the spring fixing frame is provided with a groove for limiting the metal ball pen core, and a clip of the spring is clamped in the groove of the spring fixing frame.

After the metal ball-point pen refill is filled into the pen refill cavity, the tail end of the metal ball-point pen refill is opened to open the clip of the spring, so that the metal ball-point pen refill is communicated with the main board.

The front end of the metal ball-point pen refill is covered with a detachable plastic pen cap. The plastic pen cap is covered, so that writing can be performed on the related touch screen; the plastic pen cap is removed to be used as a ball pen, and writing can be performed on paper.

As an implementation mode, the main support is provided with a clamping groove corresponding to the spring fixing frame, the periphery of the spring fixing frame is convexly provided with a sliding block matched with the clamping groove, and the clamping groove and the sliding block are matched to realize limiting of axial movement of the spring fixing frame along the pen container. The spring fixing frame is limited in the clamping groove of the main support, so that the spring fixing frame can move slightly in the axial direction.

The width of the clamping groove is larger than the length error of the metal ball pen cores of different manufacturers. The contact spring always pushes the spring fixing frame to the pen tip end and is limited by the clamping groove of the main support.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
