The present application provides a pen cap 110 for a writing pen 120. Referring to fig. 1, fig. 2, fig. 9 and fig. 10, fig. 1 is a schematic view of a pen cap according to an embodiment of the present disclosure; FIG. 2 is a cross-sectional view of the embodiment of FIG. 1 taken along line I-I; FIG. 9 is a schematic illustration of a writing assembly installation process provided by one embodiment of the present application; fig. 10 is a schematic view of the writing assembly of fig. 9 in an installed position. Referring to fig. 9 and 10, the writing pen 120 is a writing device for writing characters in a specific region of an input device. The writing pen 120 has a pen tip 121 and a grip 125. The pen tip 121 is a portion of the writing pen 120 having a writing function. The grip 125 is a portion that is gripped by a user when the writing pen 120 is used. Generally, the pen tip 121 is connected to the holding portion 125, and the pen tip 121 is disposed at an end of the holding portion 125. The grip 125 is generally in the shape of a rod or a rod-like shape so as to be held by a user, and therefore, the grip 125 may also be referred to as a barrel. In one embodiment, when the user uses the writing pen 120, the grip 125 is held and the pen tip 121 is moved, and the trace and pressure of the pen tip movement of the writing pen 120 are input to an input device (e.g., a tablet or an input screen) and transmitted to a display device via the input device for displaying on the display device. It is very useful for users who do not like to use the keyboard or are not accustomed to using the virtual keyboard. In addition, in other embodiments, the pen 120 may be used for precise drawing, such as circuit design, automatic Computer Aided Design (CAD) design, graphic design, free drawing, and text and data input. It is to be understood that the description of the writing pen 120 is merely for convenience of understanding a context of one application of the pen cap 110, and should not be construed as limiting the pen cap 110 provided in the embodiments of the present application.

Generally, when the writing pen 120 is used, in order to improve the writing feeling of the writing pen 120, a pen cap is disposed on the writing pen 120. The pen cap 110 includes a fixing portion 111 and a writing portion 112. The fixing portion 111 is used to fix the writing pen 120. The writing part 112 is connected to the fixing part 111, the writing part 112 is arranged corresponding to a pen point 121 of a writing pen 120, the writing part 112 forms at least part of an appearance surface of the pen cap 110, and a friction coefficient fc of the writing part 112 ranges from: fc < 0.3 < 0.8.

The fixing portion 111 is configured to fix the cap 110 to the writing pen 120. The fixing portion 111 may be fixed to the grip portion 125 of the writing pen 120, the pen tip 121, or both the pen tip 121 and the grip portion 125, and the fixing portion 111 may be fixed to the writing pen 120 in this embodiment. The writing unit 112 is configured to assist the writing pen 120 in writing. The writing part 112 is connected to the fixing part 111, and the writing part 112 and the fixing part 111 may be connected together by, but not limited to, a super glue, a hot melt, or the like, as long as the fixing part 111 and the writing part 112 are connected together and are not easily separated.

The writing portion 112 is generally disposed corresponding to the tip 121 of the writing pen 120, and the writing portion 112 forms at least a part of the appearance surface of the pen cap 110. That is, when the pen cap 110 is used by being fitted over the writing pen 120, the writing part 112 of the pen cap 110 directly contacts an input device to write. In one embodiment, the writing section 112 is made of an insulating material.

The range of the friction coefficient fc of the writing portion 112 is: fc < 0.3 < 0.8. The coefficient of friction is the ratio of the friction between two surfaces to the normal force acting on one surface. It is related to the roughness of the surface and not to the size of the contact area. Depending on the nature of the movement, it can be divided into a coefficient of sliding friction and a coefficient of static friction. The sliding friction force is generated by the relative sliding of two objects when the two objects are contacted with each other. The friction coefficient referred to in this embodiment is a sliding friction coefficient when the writing section 112 slides with respect to the input device while writing on the input device.

When the friction coefficient of the writing part 112 is less than or equal to 0.3, which indicates that the surface of the writing part 112 is smooth, the writing part 112 has less resistance to writing on the input device and is easy to slip on the input device; when the coefficient of friction of the writing portion 112 is greater than or equal to 0.8, which indicates that the surface of the writing portion 112 is rough, the writing portion 112 has a large resistance when writing on the input device, and it is difficult to write on the input device. Therefore, when the pen cap 110 is used, no matter the resistance of the writing part 112 is small or the resistance of the writing part 112 is large, the hand feeling of the writing pen 120 is poor when writing, and the motion track of the writing pen 120 when writing is not favorably presented on the display device.

Generally, when the friction coefficient of the writing part 112 is less than or equal to 0.3, the material of the writing part 112 is usually plastic or glass. When the friction coefficient of the writing part 112 is greater than or equal to 0.8, the writing part 112 is made of plastic or silica gel. The range of the friction coefficient fc is: when 0.3 < fc < 0.8, the material of the writing section 112 may be at least one of cloth and felt.

To sum up, compare in prior art, a pen socket 110 that this application provided, pen socket 110 includes fixed part 111 and writing portion 112, fixed part 111 be used for with the writing pen is fixed, writing portion 112 with fixed part 111 is fixed, and corresponds the nib 121 setting of writing pen 120, writing portion 112 constitutes at least partial outward appearance face of pen socket 110 is worked as pen socket 110 uses when writing pen 120 uses, but writing portion 112 direct contact input device. The range of the friction coefficient fc of the writing portion 112 is: 0.3 < fc < 0.8, so that the writing pen 120 does not slip due to too little resistance when the input device 200 (see fig. 15) writes, and is not difficult to write due to too much resistance. Therefore, the pen cap 110 of the present application improves the writing feeling of the writing pen 120, and solves the problem of difficulty in writing, so that the movement trace of the writing pen 120 during writing can be better represented on the display device.

It should be noted that, the present application proposes that the pen cap 110 is not limited to be applied to the writing pen 120, and as long as a device requiring a hard material to contact with a hard material is used, the pen cap 110 may be adopted, the pen cap 110 is disposed on one or more hard material devices (such as the writing pen 120 in the present embodiment), so as to improve the smoothness of the contact or the relative movement between the two hard material devices, and the pen cap 110 can reduce the wear resistance of the hard material devices. Meanwhile, other beneficial effects of the pen cap 110 on the writing pen 120 can be realized on other hard materials and hard material contact devices. For convenience of illustration, the pen cap 110 is applied to the writing pen 120 in the embodiments of the present application.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4 together, fig. 3 is a schematic view of a pen cap according to another embodiment of the present application; fig. 4 is a cross-sectional view of the embodiment of fig. 3 taken along line II-II. The fixing portion 111 has a receiving space 1111, the receiving space 1111 is used for receiving the pen tip 121, and the fixing portion 111 has elasticity to be fixed with the writing pen 120 when the fixing portion 111 receives the writing pen 120. The writing part 112 is wrapped at least on the outer side of the part of the fixing part 111 corresponding to the pen tip 121.

In this embodiment, the fixing portion 111 and the writing portion 112 have a laminated structure, the fixing portion 111 has an inner layer structure of the cap 110, and the writing portion 112 has an outer layer structure of the cap 110. The fixing portion 111 has an accommodating space 1111, the accommodating space 1111 is used for accommodating the pen tip 121 of the writing pen 120, and the fixing portion 111 has elasticity, and when the writing pen 120 is accommodated in the fixing portion 111, the fixing portion 111 can enable the pen cap 110 to be fixedly installed on the writing pen 120 by virtue of elasticity generated by the elasticity of the fixing portion 111. In other words, since the fixing portion 111 has elasticity, when the writing pen 120 is accommodated in the fixing portion 111, the fixing portion 111 increases the connection strength between the cap 110 and the writing pen 120 by the elasticity generated by its own elasticity, so as to clamp the writing pen 120 and prevent the cap 110 from falling off from the writing pen 120. The fixing portion 111 has elasticity, so that abnormal noise generated when the writing pen 120 writes can be effectively solved when the writing pen 120 writes. And the fixing part 111 cooperates with the writing part 112 to further enhance the writing feeling of the writing pen 120. Meanwhile, the pen point 121 is generally high in cost and easily damaged by external large impact, and the fixing portion 111 can protect the pen point 121 of the writing pen 120 from being damaged by external force, for example, from falling.

The writing part 112 is wrapped at least on the outer side of the part of the fixing part 111 corresponding to the pen tip 121. Including but not limited to the following. In one embodiment, referring to fig. 1 and 2, the writing part 112 completely covers the fixing part 111. In another embodiment, referring to fig. 3 and 4, the writing part 112 only wraps the outside of the part of the fixing part 111 corresponding to the pen tip 121. In another embodiment, the writing section 112 may be wrapped around at least the outer side of the portion of the fixing section 111 corresponding to the pen tip 121. When the writing part 112 wraps the fixing part 111, the wear resistance of the pen cap 110 can be increased, and when the writing pen writes on the input device, the writing part is directly contacted with the input device, for example, in the process of writing, drawing and the like of the writing pen, the fixing part 111 is prevented from being worn out too fast, so that the pen point 121 is worn.

Referring to fig. 5 and 6, fig. 5 is a schematic view of a pen cap according to another embodiment of the present application; fig. 6 is a cross-sectional view of the embodiment of fig. 5 taken along line III-III. The fixing portion 111 has a through hole 1112, and the writing portion 112 has an aperture 1121, and the aperture 1121 communicates with the through hole 1112.

In this embodiment, the fixing portion 111 has one or more through holes 1112, and the through holes 1112 are disposed at one end of the fixing portion 111 surrounding the pen tip 121. The writing part 112 has an aperture 1121, the number of the apertures 1121 may be one or more, and the apertures 1121 are communicated with the through hole 1112.

In the present embodiment, since the fixing portion 111 has elasticity and the cap 110 needs to be fixedly attached to the writing pen 120 by the elasticity of the fixing portion 111 itself, the fixing portion 111 is spread when the cap 110 is fitted into the writing pen 120. Therefore, resistance exists when the pen cap 110 is installed in the writing pen 120, and if the through hole 1112 is not provided, the pen cap 110 is difficult to be installed in the pen point 121 because air exists at the bottom of the pen cap 110, and even the pen cap 110 cannot be completely attached to the pen point 121, so that an air gap exists between the pen cap 110 and the pen point 121, the installation effect is poor, and the writing experience is affected. Furthermore, the air between the cap 110 and the nib 121 is compressed, and the compressed air continuously exerts a force on the cap 110, which may cause the cap 110 to easily fall off. Therefore, the through hole 1112 is disposed such that when the pen cap 110 is sleeved on the pen tip 121, air in the pen cap 110 is exhausted through the through hole 112 and the aperture 1121, and therefore, the pen cap 110 is more easily sleeved on the pen tip 121, and the pen cap 110 is more closely attached to the pen tip 121, so that the pen cap 110 is less prone to slipping off.

Further, in one embodiment, the size of the aperture 1121 is smaller than the size of the through hole 1112, and a plurality of apertures 1121 are disposed corresponding to the through hole 1112.

In this embodiment, the number of the apertures 1121 may be one or more, and the size of the apertures 1121 is smaller than that of the through holes 1112. The apertures 1121 may be provided in the writing part 112, or may be apertures 1121 formed in the material of the writing part 112 itself, and in short, the apertures 1121 may communicate with the through holes 1112.

In particular, in this embodiment, the aperture 1121 is visible to the human eye. In another embodiment, the apertures 1121 are made of a material of itself, and the apertures 1121 are invisible to human eyes, so that the apertures 1121 communicate with the through holes 1112, and the through holes 1112 are shielded by the writing part 112. Because the through hole 1112 is shielded by the writing part 112, the through hole 1112 cannot be exposed out of the appearance of the pen cap 110, thereby avoiding the influence of water vapor, dust and the like entering the interior of the pen cap 110 on the writing pen 120 and improving the appearance integrity and the attractiveness of the pen cap 110.

Referring to fig. 7 and 8, fig. 7 is a schematic view of a pen cap according to another embodiment of the present application; figure 8 is a cross-sectional view of the embodiment of figure 7 taken along line IV-IV. The writing section 112 has a housing space 1122 and an opening 1123 communicating with the housing space 1122, and the housing space 1122 houses the pen tip 121. The writing portion 112 includes a first surface 1124, an end 1125, and a second surface 1126. The first surface 1124 is an exterior surface of the writing part 112, the second surface 1126 is an interior surface of the writing part 112, the end face 1125 connects the first surface 1124 and the second surface 1126, and the end face 1125 has the opening 1123. The fixing portion 111 is connected to the end face 1125.

The fixing portion 111 may be connected to the writing portion 112 through the end face 1125, but is not limited to the following. In one embodiment, the fixing portion 111 is connected to the writing portion 112 by glue disposed on the end face 1125. In another embodiment, the fixing portion 111 and the writing portion 112 are sewn together such that the fixing portion 111 is connected to the writing portion 112 through the end face 1125. As long as the fixing portion 111 can be secured by connecting the writing portion 112 to the end face 1125. In this embodiment, the fixing portion 111 connects the writing portion 112 with the end face 1125, so that the pen cap 110 is lighter and thinner, and materials used for the pen cap 110 can be saved.

Further, in the present embodiment, the fixing portion 111 has an accommodating space 1113, the accommodating space 1113 communicates with the accommodating space 1122, and the fixing portion 111 has elasticity so as to be fixed to the writing pen 120 when the fixing portion 111 accommodates the writing pen 120.

In the present embodiment, the fixing portion 111 has an accommodating space 1113, the accommodating space 1113 communicates with the accommodating space 1122, and the accommodating space 1113 and the accommodating space 1122 at least accommodate the pen tip 121 together. In one embodiment, the receiving space 1113 and the receiving space 1122 together receive the pen tip 121. In another embodiment, the accommodating space 1113 and the accommodating space 1122 together accommodate the pen tip 121 and a portion of the grip 125. It is sufficient that the accommodation space 1113 and the accommodation space 1122 can accommodate the pen tip 121. The fixing portion 111 has elasticity, and when the fixing portion 111 is not stressed (i.e., the fixing portion 111 is in a natural state), the diameter of the fixing portion 111 is smaller than that of the writing pen 120, so that the fixing portion 111 fixes the pen cap 110 on the writing pen 120 by elastic contraction.

Because the fixing portion 111 has elasticity, when the writing pen 120 is accommodated in the fixing portion 111, the fixing portion 111 increases the connection strength between the cap 110 and the writing pen 120 by means of the elasticity generated by the elasticity of the fixing portion 111, so that the writing pen 120 can be clamped tightly, and the cap 110 is prevented from falling off from the writing pen 120.

In other embodiments, the fixing portion 111 may have a snap, a hook and loop fastener, a bolt connection structure, etc., as long as the fixing portion 111 can be fixedly connected to the writing pen 120, and the cap 110 can be prevented from falling off from the writing pen 120.

In one embodiment, the material of the fixing portion 111 includes at least one of rubber and silicone. The writing part 112 material includes at least one of cloth and felt.

In the present embodiment, the material of the fixing portion 111 includes at least one of rubber and silicone, as long as the fixing portion 111 has elasticity. The writing part 112 material includes at least one of cloth and felt so long as the range of the friction coefficient fc of the writing part 112 is: fc is more than 0.3 and less than 0.8.

When the fixing portion 111 is fixed to the writing pen 120, the fixing portion 111 is made of at least one of rubber and silica gel, so that the fixing portion 111 is enhanced in connection strength between the pen cap 110 and the writing pen 120 by elasticity of the fixing portion 111, the writing pen 120 can be clamped tightly, and the pen cap 110 is prevented from falling off from the writing pen 120.

Since the pen tip 121 is generally made of a hard material, the writing pen 120 is apt to make a rattling noise when writing. When the fixing part 111 receives the writing pen 120, the fixing part is fixed with the writing pen 120; the writing part 112 is at least covered on the outer side of the part of the fixing part 111 corresponding to the pen point 121. Since the range of the friction coefficient fc of the writing portion 112 is: fc is more than 0.3 and less than 0.8, so that good damping feeling can be provided, the writing hand feeling is improved, and the effect similar to paper writing is realized. Meanwhile, when the writing part 112 wraps the fixing part 111, the wear resistance of the pen cap 110 can be increased, and when the writing pen 120 writes on the input device, the writing part 112 directly contacts with the input device, for example, in the process of writing, drawing and the like by the writing pen 120, the pen point 121 is prevented from being worn and lost too fast. Meanwhile, the materials such as silica gel, rubber, cloth and felt adopted by the pen cap 110 are common materials, so that the materials are easy to obtain, and the manufacturing cost is low.

Referring to fig. 9 and 10, fig. 9 is a schematic view illustrating a process of installing a writing element according to an embodiment of the present application; fig. 10 is a schematic view of the writing assembly of fig. 9 in an installed position. The present application provides a writing assembly 100, the writing assembly 100 including a writing pen 120, and a pen cap 110 as described in any of the previous embodiments. Please refer to the above description for the pen cap 110, which is not described herein. The writing pen 120 has a pen tip 121, and the writing part 112 of the pen cap 110 is disposed corresponding to the pen tip 121.

In this embodiment, during the process of installing the pen cap 110 (as shown in fig. 9), air is pushed out from the through holes 1112 and the apertures 1121 along the path shown by the dotted line with arrows, so that the pen cap 110 and the writing book are better installed and attached. After the assembly is completed (see fig. 10), the cap 110 and the writing pen 120 are completely attached.

Referring to fig. 11 and 12, fig. 11 is a view illustrating an included angle of an appearance of a fixing portion of a pen cap according to an embodiment of the present application; fig. 12 is a schematic diagram of an included angle of an appearance of a writing pen according to an embodiment of the present application. The shape included angle α of the fixing portion 111, the shape included angle of the pen tip 121 is β, and α < β.

The included angle α (as shown in fig. 11) of the shape of the fixing portion 111 is an included angle formed by extending and intersecting a line on the side of the fixing portion 111 close to the pen tip 121 to a point, as shown in the same view as fig. 2. For example, when the center line La of the pen cap 110 is disposed along a direction perpendicular to the horizontal plane, one side of the fixing portion 111 close to the pen tip 121 has two lines symmetrical to the center line La, extension lines L1 and L2 of the two lines symmetrical to the center line intersect at a point, and the point is on the center line La of the pen cap 110, and an included angle formed by intersection of extension lines L1 and L2 of the two lines symmetrical to the center line La is an outer shape included angle α of the fixing portion 111.
