Description

Technical Field

[0001] The utility model relates to the technical field of touch pens, and in particular to a touch pen head assembly and a touch pen thereof. Background Art

[0002] With the advancement of technology, more and more people like to use mobile phones, tablets and other electronic devices for note-taking or drawing. In order to enable users to obtain a better writing and drawing experience, the demand for stylus pens is also increasing.

The stylus pen provided by the utility model can be charged by directly inserting the plug into the socket of the power supply device when charging is needed, which is convenient to use. In addition, the angle between the plug and the pen body can be adjusted by rotating the plug relative to the pen body with the rotating shaft as the center, so that the relative position between the pen body and the power supply device can be adjusted when the stylus pen is connected to the power supply device, thereby reducing the space occupied and further improving the convenience of using the stylus pen.

[0004] The contact of the existing stylus pen structure is usually made of hard plastic or metal material, and cooperates with a spring to provide elastic protection for the pen core. One end of the contact is connected to a conductive alloy tube for transmitting the electrical signal emitted by the device in the pen body. In actual use, the stylus pen will inevitably wear out the contact or pen tip after repeated use or bumping. When excessively worn, the sensitivity of use often decreases. After the above-mentioned situation occurs in the stylus pen, it is often impossible to replace the worn contact or pen tip alone, resulting in high cost of use. Summary of the invention

[0005] The utility model overcomes the deficiencies of the prior art and provides a stylus pen head assembly and a stylus pen thereof.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a stylus pen head assembly, comprising:

[0007] A core component, wherein the core component is made of a flexible conductive material and is used to transmit electrical signals in the stylus pen for writing;

[0008] A pen tip component, wherein an axial hole component is opened inside the pen tip component, the axial hole component passes through the inside of the pen tip component to both ends, and both ends of the inner side of the axial hole component are provided with connecting pieces for detachably connecting the core component and the pen shaft, and the core component is installed at one end of the pen tip component through the connecting piece.

[0009] In a preferred embodiment of the utility model, the refill component includes: a conductive connecting handle, a conductive contact fixed at one end of the conductive connecting handle, and a conductive block fixed at the other end of the conductive connecting handle; a refill sleeve is sleeved on the side of the conductive contact, and the refill sleeve is a hollow structure.

[0010] In a preferred embodiment of the present invention, the conductive connecting handle, the conductive contact and the conductive card block are all made of flexible conductive material in one piece.

[0011] In a preferred embodiment of the utility model, the refill sleeve includes: a conical column, a first fixed column fixed to the end of the conical column with a smaller diameter, and a second fixed column fixed to the end of the conical column with a larger diameter; the diameter of the end of the conical column with a larger diameter is larger than the diameter of the second fixed column, and the end of the conical column with a larger diameter overlaps with one end of the pen head component.

[0012] In a preferred embodiment of the utility model, the length dimension of the conductive connecting handle is the same as the length dimension of the refill sleeve, the diameter dimensions of the conductive contact and the conductive card block are larger than the diameter dimension of the conductive connecting handle, and one end of the conductive contact and the conductive card block are overlapped with the two ends of the first fixing column and the second fixing column respectively.

[0013] In a preferred embodiment of the utility model, the axial hole component includes: a first axial hole, a second axial hole and a third axial hole which are sequentially opened inside the pen head component from left to right; the diameter size of the first axial hole is smaller than the size of the second axial hole and the third axial hole respectively, and the side surface of the second fixing column is located on the inner side of the first axial hole.

[0014] In a preferred embodiment of the utility model, the connecting member includes: an internal thread arranged on the inner side of the first axial hole and the third axial hole, and an external thread arranged on the side of the second fixing column; the second fixing column is installed on the inner side of the first axial hole by threadedly connecting the external thread with the internal thread.

[0015] In a preferred embodiment of the utility model, the conductive connecting handle and the refill sleeve are both coaxially arranged with the pen head component.

[0017] In a preferred embodiment of the present invention, one end of the pen shaft of the stylus pen is connected to the pen head component through the connecting piece.

[0018] The utility model solves the defects existing in the background technology, and has the following

[0019] Beneficial effects:

[0020] (1) The utility model provides a stylus pen tip assembly and a stylus pen thereof. The stylus pen tip assembly is composed of a core component and a tip component, and a connecting piece is provided on the axial hole component inside the core component, so that the core component and the pen holder of the stylus pen can be detachably connected to the two ends of the tip component respectively. During use, if the core component, the tip component and the pen holder are used multiple times or bumped, causing the contact tip and other parts to be worn, only the worn parts need to be disassembled and replaced separately, thereby increasing the life of the stylus pen during use and reducing the cost of use.

[0021] (2) In the present invention, the conductive connection handle, the conductive contact and the conductive card block are made of flexible conductive materials.

Secondly, the softness and elasticity can ensure that the user will not make noise when writing or drawing, and provide the user with sufficient damping, so that the user has a better, more delicate and more realistic writing and drawing experience. Finally, since the length of the conductive connection handle is the same as the length of the refill sleeve, the diameters of the conductive contact and the conductive card block are larger than the diameter of the conductive connection handle. When the conductive connection handle is located inside the refill sleeve, the conductive contact and the conductive card block can form an "H"-shaped clamping connection, so that the stylus pen is not prone to falling off during use, thereby improving the reliability of the stylus pen.

DETAILED DESCRIPTION

[0028] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a stylus pen tip assembly includes:

[0030] A core component 1, wherein the core component 1 is made of a flexible conductive material and is used to transmit electrical signals in the stylus for writing; a head component 2, wherein an axial hole component 3 is provided inside the head component 2, and the axial hole component 3 passes through the inside of the head component 2 to both ends, and both ends of the inner side of the axial hole component 3 are provided with connectors for detachably connecting the core component 1 and the pen body, and the core component 1 is installed at one end of the head component 2 through the connector.

[0031] It should be noted that, by forming the stylus pen tip assembly from a core component 1 and a tip component 2, and providing a connecting piece on the axial hole component 3 inside the core component 1, the core component 1 and the pen shaft of the stylus pen (not shown in the figure) can be detachably connected to the two ends of the tip component 2 respectively. During use, if the core component 1, the tip component 2 and a certain part of the pen shaft are used multiple times or bumped, causing wear on the contact and other parts, it is only necessary to disassemble and replace the worn parts separately, thereby increasing the life of the stylus during use and reducing the cost of use.

[0032] like Figure 2 As shown, a conductive connecting handle 11, a conductive contact 12 fixed at one end of the conductive connecting handle 11, and a conductive block 13 fixed at the other end of the conductive connecting handle 11; a core sleeve 14 is sleeved on the side of the conductive contact 12, and the core sleeve 14 is a hollow structure.

[0033] It should be noted that the conductive connection handle 11, the conductive contact 12 and the conductive card block 13 are all made of a flexible conductive material; the conductive connection handle 11 and the refill sleeve 14 are coaxially arranged with the pen head component 2; by making the conductive connection handle 11, the conductive contact 12 and the conductive card block 13 of flexible conductive materials, firstly, the conductive contact 12 can transmit the electrical signal in the stylus pen, ensuring that the user will not experience interruption during use, and secondly, the softness and elasticity can ensure that the user will not make noise when writing and drawing, and provide the user with sufficient damping, so that the user has a better, more delicate and more realistic writing and drawing experience. The conductive contact 12 made of flexible conductive material will not cause damage to the screen compared to the refill made of hard plastic or metal. The shape of the conductive contact 12 is preferably spherical, which can meet the writing and drawing needs of users in most cases.

[0034] Among them, the flexible conductive material is preferably conductive rubber. Conductive rubber is made by evenly distributing conductive particles such as glass silver-plated, aluminum silver-plated, and silver in silicone rubber, and making the conductive particles contact through pressure to achieve good conductive properties. It has good electromagnetic sealing and water vapor sealing capabilities, and can provide good conductivity under a certain pressure. The conductive rubber is made of good conductivity and long service life, and can provide sufficient damping, so that users have a better, more delicate and more realistic writing and painting experience.

[0035] like Figure 3 As shown, the refill cover 14 includes: a conical column 141, a first fixing column 142 fixed to the end of the conical column 141 with a smaller diameter, and a second fixing column 143 fixed to the end of the conical column 141 with a larger diameter; the diameter of the end of the conical column 141 with a larger diameter is greater than the diameter of the second fixing column 143, and the end of the conical column 141 with a larger diameter overlaps one end of the pen head component 2.

[0036] It should be noted that the length of the conductive connecting handle 11 is the same as the length of the refill sleeve 14, and the diameters of the conductive contact 12 and the conductive card block 13 are both larger than the diameter of the conductive connecting handle 11. One end of the conductive contact 12 and the conductive card block 13 are overlapped with the two ends of the first fixed column 142 and the second fixed column 143 respectively; since the length of the conductive connecting handle 11 is the same as the length of the refill sleeve 14, and the diameters of the conductive contact 12 and the conductive card block 13 are both larger than the diameter of the conductive connecting handle 11, after the conductive connecting handle 11 is located inside the refill sleeve 14, the conductive contact 12 and the conductive card block 13 can form an "H"-shaped clamping connection, so that it is not easy to fall off during use, thereby improving the reliability of the stylus. Since the diameter of the larger end of the conical column 141 is larger than the diameter of the second fixed column 143, the larger end of the conical column 141 overlaps with one end of the pen head component 2, so that after the pen core cover 14 is connected to the inside of the shaft hole component 3, the conical column 141 can limit the depth of the pen core cover 14 extending into the shaft hole component 3.

[0037] like Figure 4 As shown, the axial hole component 3 includes: a first axial hole 31, a second axial hole 32 and a third axial hole 33 which are opened inside the pen head component 2 from left to right; the diameter size of the first axial hole 31 is smaller than the size of the second axial hole 32 and the third axial hole 33 respectively, and the side surface of the second fixing column 143 is located on the inner side of the first axial hole 31.

[0038] It should be noted that the first axial hole 31 is used to dock with the pen core sleeve 14, the third axial hole 33 is used to dock with the pen body of the stylus pen, and the second axial hole 32 is used to connect the first axial hole 31 and the third axial hole 33; if the electronic device on the pen body needs to dock with one end of the conductive card block 13, it can pass through the second axial hole 32 through the third axial hole 33, so as to dock with the conductive card block 13 in the first axial hole 31.

[0039] In some embodiments, the connecting member includes: an internal thread arranged on the inner side of the first axial hole 31 and the third axial hole 33, and an external thread (not shown in the figure) arranged on the side of the second fixing column 143; the second fixing column 143 is installed on the inner side of the first axial hole 31 by threaded connection between the external thread and the internal thread.

[0040] It should be noted that, through the external thread set on the side of the second fixing column 143, when the core component 1 is connected and installed to one end of the pen head component 2, the external thread on the side of the second fixing column 143 is screwed into the inner side of the first axial hole 31 and cooperates with the internal thread on the inner side of the first axial hole 31, thereby completing the connection and installation of the core component 1. When the pen holder of the stylus pen is connected and installed to the other end of the pen head component 2, one end of the pen holder is cooperated with the internal thread on the inner side of the third axial hole 33, thereby completing the connection and installation of the pen holder.

[0041] A stylus pen comprises any one of the stylus pen head components mentioned above.

[0042] In some embodiments, one end of the pen holder of the stylus pen is connected to the pen head component 2 via a connecting piece.

[0043] When the utility model is used, when the user assembles, the conductive connecting handle 11 is passed through the core sleeve 14, so that the conductive contacts 12 and the conductive clamping block 13 at both ends of the conductive connecting handle 11 can form an "H"-shaped clamping connection. When the core component 1 is connected and installed to one end of the pen head component 2, the outer thread on the side of the second fixing column 143 in the core sleeve 14 is screwed into the inner side of the first shaft hole 31 and matched with the inner thread on the inner side of the first shaft hole 31. At the same time, since the diameter of the larger end of the conical column 141 in the core sleeve 14 is larger than the diameter of the second fixing column 143, the larger end of the conical column 141 is connected to one end of the pen head component 2. The ends are overlapped, so that after the core sleeve 14 is connected to the inner side of the first axial hole 31, it can limit the depth of the core sleeve 14 extending into the first axial hole 31. When the pen body of the touch pen is connected and installed to the other end of the pen head component 2, one end of the pen body is matched with the internal thread inside the third axial hole 33, so as to complete the connection and installation of the pen body. At the same time, during use, if the core component 1, the pen head component 2 and a certain part of the pen body are used multiple times or bumped, causing the contact and other parts to be worn, only the worn parts need to be disassembled and replaced separately, thereby prolonging the life of the touch pen during use and reducing the cost of use.

[0044] The above is based on the ideal embodiment of the utility model as inspiration. Through the above description, it is obvious to those skilled in the art that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
