Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic overall structure diagram of an embodiment of a pen-type input device of the present application, and fig. 2 is a schematic cross-sectional structure diagram of the pen-type input device at A-A in the embodiment of fig. 1; it should be noted that, the pen-type input device in the application may be used in combination with an electronic device, where the electronic device may include an electronic device with a touch display screen, such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. The pen-type input device 10 in this embodiment includes, but is not limited to, the following structural composition: nib device 100 and housing 200. It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may alternatively include other steps or elements not listed or inherent to such process, method, article, or apparatus.

In particular, the housing 200 has a pen-shaped peripheral contour, which may be a cylinder, a column or a column-like shape, having a similar profile to a pen. The housing 200 is provided with a cavity 2000, the cavity 2000 being provided with an opening 201.

Optionally, the nib device 100 includes a pen core 110 and a protective sheath 130. The pen core 110 comprises a pen core main body 111 and a pen tip 112 which are integrally formed, wherein a groove 1111 is formed in the outer side wall of the pen core main body 111, and the groove 1111 is used for reducing the hardness of the pen core main body 111. The groove 1111 corresponds to a half-cut structure formed in the pen core body 111, and further serves to reduce the hardness of the pen core body 111, i.e., the writing hardness of the pen tip 112. The larger the volume of the groove 1111, the more the hardness of the cartridge body 111 decreases.

Wherein the nib 112 protrudes from the opening 201. Specifically, the pen tip 112 may be disposed in the protective sleeve 130, one end of the protective sleeve 130 is inserted into the opening 201 of the housing 200, and the other end is exposed from the opening 201. The protective sleeve 130 is wrapped at one end of the pen core main body 111 near the pen point 112, wherein the protective sleeve 130 may be made of rubber or other material with certain elasticity and softness, and is wrapped at the periphery of the pen point 112, so as to protect the pen point 112 and buffer the pen touch. The outer peripheral surface of the protective case 130 is cone-shaped, and the outer peripheral surface of the protective case 130 serves as a contact surface when the pen-type input device 10 is in contact with the touch screen.

Alternatively, the groove 1111 may be filled with a material having a hardness less than that of the cartridge body 111, such as silica gel, soft resin, or the like. The pen core 110 (including the pen core body 111 and the pen tip 112) is made of a conductive material, and specifically may be a metal or an alloy such as stainless steel, an aluminum alloy, a magnesium alloy, and the like. With continued reference to FIG. 2, the cross-section of the recess 1111 may be rectangular in configuration. Further, referring to fig. 3 together, fig. 3 is a schematic view of a part of a pen-type input device according to another embodiment of the pen core, and in the embodiment of fig. 3, the cross section of the groove 1111 is a wedge-shaped structure, and the width of the wedge-shaped structure gradually decreases from the outer side wall of the pen core main body 111 to the inside.

Referring to fig. 4, fig. 4 is a schematic view showing a partial structure of a pen-type input device according to another embodiment of the pen refill, in which a groove 1111 is formed in an annular structure along an outer circumference of the pen refill body 111. The groove 1111 of the ring-like structure may allow the cartridge body 111 to achieve a reduction in hardness in multiple directions. Wherein, the method comprises the following steps of. The annular groove 1111 is not communicated with the cartridge body 111, i.e. the cartridge body 111 is not cut off, and the two purposes are to ensure that the cartridge body 111 has a certain connection strength on one hand and to keep the cartridge body 111 in an electrically communicated state on the other hand.

Alternatively, referring to fig. 5, fig. 5 is a schematic view showing a partial structure of a pen-type input device according to another embodiment of the pen core, in which the number of grooves 1111 is plural, and plural grooves 1111 are sequentially arranged along the axial direction of the pen core main body 111. In this embodiment, by providing a plurality of grooves 1111, it is possible to make the cartridge body 111 realize multi-dimensional hardness reduction at multiple positions, avoiding the problem that the hardness reduction amplitude caused by the groove structure at a single position is small or the connection strength of the cartridge body is affected. The greater the number of grooves 1111, the lower the overall hardness of the cartridge body 111, and the softer the nib 112. It should be noted that the terms "first," "second," and "third" in the embodiments herein are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

Referring to fig. 6, fig. 6 is a schematic view of a part of a pen-type input device according to another embodiment of the pen core, in which the recess 1111 is formed as a wedge structure, but the wedge structure is not limited to a triangular wedge structure with straight edges, and may be a wedge structure with arc edges in fig. 6, so that the hardness of the pen core main body 111 is reduced, and the volume of the recess 1111 can be reduced to the greatest extent, because the larger the volume of the recess 1111 is, the more the volume of the pen core main body 111 is hollowed out, which affects the connection strength of the pen core main body 111.

Referring to fig. 7, fig. 7 is a schematic overall structure of another embodiment of the pen-type input device of the present application, in which the pen-type input device 10 also includes a pen tip device 100 and a housing 200, and unlike the previous embodiment, the pen-type input device 10 of the present embodiment further includes a circuit board 300; the circuit board 300 is disposed within the cavity 2000 of the housing 200. For detailed structural features of the nib assembly, reference is made to the description of the several embodiments described above.
