The mobile phone and the tablet computer are electronic equipment provided with the cellular communication module.

Referring to fig. 1 and fig. 2 together, fig. 1 isbase:Sub>A schematic overall structure diagram of an embodiment ofbase:Sub>A pen-type input device of the present application, and fig. 2 isbase:Sub>A schematic structural cross-sectional view of the pen-type input device atbase:Sub>A-base:Sub>A in the embodiment of fig. 1; it should be noted that the pen-type input device in the present application may be used in cooperation with an electronic device, and 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 the present embodiment includes, but is not limited to, the following structural components: a nib device 100 and a housing 200. It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or may alternatively include other steps or elements inherent to such process, method, article, or apparatus.

Specifically, the housing 200 has a pen-shaped outer peripheral profile, which may be a cylindrical, pillar or pillar-like shape structure having an outer profile similar to a pen. The housing 200 is provided with a cavity 2000, said cavity 2000 being provided with an opening 201.

Optionally, the pen tip device 100 includes a pen core 110, a control device (not shown, the detailed structure will be described in detail in the following embodiments), and a protective sleeve 130. The pen core 110 comprises a pen core main body 111 and a pen point 112, and the control device is used for controlling the distance 102 between the pen core main body 111 and the pen point 112 so as to change the pen touch hardness of the pen point 112. The nib 112 protrudes from the opening 201. Specifically, the pen tip 112 may be disposed in the protective sheath 130, one end of the protective sheath 130 is inserted into the opening 201 of the housing 200, and the other end is exposed out of the opening 201. The protective sleeve 130 is wrapped around one end of the pen core body 111 close to the pen point 112, wherein the protective sleeve 130 may be made of rubber or other materials with certain elasticity and softness, and is wrapped around the pen point 112 to protect the pen point 112 and buffer pen touch. The outer circumference of the protective sleeve 130 is cone-shaped, and the outer circumference of the protective sleeve 130 is used as a contact surface when the pen-type input device 10 contacts the touch screen.

Because a gap exists between the refill main body 111 and the pen point 112, under the action of the control device, the distance 102 between the refill main body 111 and the pen point 112 is different, so that different touch hardness of the pen point is generated, and generally, the larger the gap is, the smaller the hardness is; conversely, the smaller the gap, the greater the hardness.

Optionally, referring to fig. 3, fig. 3 is a schematic partial sectional view of another embodiment of a pen-type input device according to the present application, in this embodiment, the pen-type input device 10 also includes a pen-tip apparatus 100 and a housing 200.

The housing 200 has a pen-shaped outer contour, which may be a cylinder, a column or a column-like structure, and has an outer contour similar to a pen. The housing 200 is provided with a cavity 2000, said cavity 2000 being provided with an opening 201.

Optionally, the pen tip device 100 includes a pen core 110, a control device (not shown, the detailed structure will be described in detail in the following embodiments), and a protective sleeve 130.

Alternatively, in this embodiment, the connecting section 113 may be multiple, and the multiple connecting sections 113 are sequentially arranged along the axial direction (i.e. the length direction) of the pen core. The adjacent intervals 103 of the pen core main body 111, the connecting sections 113 and the pen tip 112 are controlled by the control device, which means the gaps between the pen core main body 111 and the connecting sections 113, between the connecting sections 113 and the adjacent connecting sections 113 and between the connecting sections 113 and the pen tip 112.

Due to the existence of gaps between the pen core main body 111 and the connecting section 113, between the connecting section 113 and the adjacent connecting section 113 and between the connecting section 113 and the pen point 112, under the action of the control device, the touch hardness of the pen point 112 is different due to the change of the adjacent distance, and generally, the larger the gap is, the smaller the hardness is; conversely, the smaller the gap, the greater the hardness. Referring to fig. 3 to 5, fig. 4 is a schematic diagram illustrating a hardness state of a pen tip of the pen-type input device, and fig. 5 is a schematic diagram illustrating a hardness state of the pen tip of the pen-type input device; in fig. 3 to 5, the adjacent distance 103 between the pen point 112 and the pen refill main body 111 is gradually decreased, so that the tactile hardness of the pen point 112 is gradually increased, that is, the tactile hardness of the pen point 112 in fig. 5 is greater than that of the pen point 112 in fig. 4, and the tactile hardness of the pen point 112 in fig. 4 is greater than that of the pen point 112 in fig. 3.

Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

The nib 112 protrudes from the opening 201. Specifically, the pen tip 112 and the connecting segment 113 may be disposed in the protective sheath 130, one end of the protective sheath 130 is inserted into the opening 201 of the housing 200, and the other end is exposed out of the opening 201. The protective sleeve 130 is wrapped at one end of the pen core main body 111 close to the connecting section 113, wherein the protective sleeve 130 may be made of rubber or other materials with certain elasticity and softness, and is wrapped around the pen point 112 to protect the pen point 112 and buffer pen touch. The outer circumference of the protective sleeve 130 is cone-shaped, and the outer circumference of the protective sleeve 130 is used as a contact surface when the pen-type input device 10 contacts the touch screen.
