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 capable of preventing accidental touches. Background Art

[0002] With technological advancements, touch technology has become widely used in various electronic devices, especially smartphones, tablets, and touchscreen displays. More and more people like to use these devices for note-taking and drawing. As an important input tool, the stylus provides users with a more precise and convenient touch experience. To provide users with a better writing and drawing experience, the demand for styluses is also increasing.

[0003] The existing stylus pen structure usually has a pen tip made of hard plastic or metal, and one end of the pen tip is connected to a conductive contact and a conductive alloy tube for transmitting the electrical signal emitted by the device in the pen body. In the working principle of the stylus, capacitance change is the key factor in its recognition of touch input. When the stylus pen tip approaches or contacts the capacitive screen, it will cause the electric field distribution on the screen to change, which is then recognized as touch input by the sensor inside the screen. However, when the user places the stylus pen on the capacitive screen at will without actively operating it, the direct contact between the pen tip and the screen may accidentally trigger screen operations, resulting in unnecessary program startup, page jumps or information input, which can easily cause false touches. In addition, when writing or drawing, it lacks sensitive response to different force changes and cannot provide pressure feedback similar to that of real writing tools, affecting the creative accuracy and user experience. Summary of the Invention

[0004] The utility model overcomes the deficiencies of the prior art and provides a stylus pen head assembly and a stylus pen that can prevent accidental touches.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a stylus pen tip assembly for preventing accidental touch, comprising: a pen tip body, an axial hole component provided inside the pen tip body, and a refill component installed at the bottom end of the pen tip body;

[0006] The refill component includes: a refill sleeve mounted at the bottom end of the pen body, a conductive column, a conductive connecting handle, and a conductive contact arranged on the inner side of the refill sleeve from top to bottom, and a connecting pin arranged on the top of the conductive column; a damping spring is sleeved on the side of the conductive connecting handle;

[0007] The top of the damping spring is fixed to the bottom of the conductive column, and the bottom is fixed to the top of the conductive contact; the bottom of the conductive connecting handle is fixed to the top of the conductive contact, and the length of the damping spring is greater than the length of the conductive connecting handle.

[0008] In a preferred embodiment of the present invention, the shaft hole component passes through the interior of the pen head body to both ends and is used to achieve a detachable connection between the refill component and the pen shaft; the side surface of the conductive contact is slidably connected to the inner side of the refill sleeve.

[0009] In a preferred embodiment of the present invention, a stepped structure is provided on the inner side of the refill sleeve, a clamping ring is fixed to the bottom end of the conductive column, and the top of the clamping ring contacts the bottom of the stepped structure.

[0010] In a preferred embodiment of the present invention, the side surface of the clamping ring is interference fit with the inner side of the refill sleeve.

[0011] In a preferred embodiment of the present invention, a movable groove is provided on the top of the conductive column, the side surface of the connecting pin is slidably connected to the inner side of the movable groove, and a reset spring is fixed between the inner bottom of the movable groove and the bottom of the connecting pin.

[0012] In a preferred embodiment of the present invention, the conductive column, the conductive connecting handle, the conductive contact and the connecting needle are all made of flexible conductive materials and are used to transmit electrical signals in the stylus for writing.

[0013] In a preferred embodiment of the present invention, 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 body from top to bottom; the inner side of the first axial hole is provided with an internal thread for detachable connection to the pen shaft, and the top end of the pen core sleeve is installed inside the third axial hole.

[0014] In a preferred embodiment of the present invention, the diameter of the first axial hole is successively larger than that of the second axial hole and the third axial hole.

[0015] In a preferred embodiment of the present invention, the side surface of the refill sleeve close to the top end is threadedly connected to the inner side of the third shaft hole.

[0016] The utility model provides a touch pen, comprising a pen head assembly as described in any one of the above items, wherein the bottom end of the pen shaft of the touch pen is connected to the pen head body through the shaft hole component.

[0017] The present invention solves the defects in the background technology and has the following beneficial effects:

[0018] (1) The present invention provides a stylus pen tip assembly and a stylus pen that can prevent accidental touches. The stylus pen tip assembly is composed of a pen tip body, an axis hole component and a refill component. The refill sleeve, a conductive column, a conductive connecting handle, a conductive contact, a connecting needle and a damping spring cooperate to disconnect the conductive connecting handle from the conductive column. Even if the conductive contact is in direct contact with the screen, the electrical signal will not be transmitted to the conductive contact, causing a change in the electric field distribution on the screen, thereby effectively preventing accidental touches. When the user presses down on the pen body, the conductive contact is pressed into the refill sleeve and squeezes the damping spring to push the conductive connecting handle and contact the conductive column. At this time, the electrical signal emitted by the device in the pen body can be transmitted to the capacitive screen through the conductive contact, triggering the screen to respond and realize writing. This not only solves the problem of accidental touches, but also realizes the perception of writing force through the extension and retraction of the conductive contact, thereby improving the pressure experience.

The conductive column is installed from the bottom to the top of the refill sleeve. The clamping ring contacts the bottom of the stepped structure, and the side surface is interference fit with the inner side of the refill sleeve. This not only ensures the stable installation of the conductive column in the refill sleeve, but also provides the necessary friction force through the interference fit to prevent the conductive column from loosening or falling off during use.

[0020] (3) In the present invention, a movable groove is provided on the top of the conductive column. When the pen holder of the touch pen is detachably connected to the top of the pen head body, the movable groove, the reset spring and the connecting needle cooperate to form a retractable effect formed by the reset spring and the connecting needle, thereby forming a variable margin when contacting the conductive pen column on the pen holder. In addition, when the length of the conductive pen column on the pen holder fluctuates due to differences in brand or model of the touch pen holder, longer or shorter pen holders can achieve better contact with the connecting needle, thereby achieving adaptation to the conductive pen columns on pen holders of different lengths. This not only ensures stable electrical signal transmission, but also avoids the problem of difficult installation of the pen head and the pen holder, thereby significantly improving the versatility and compatibility of the pen head.

DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to 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 components related to the present invention.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, a stylus pen tip assembly for preventing accidental touches includes: a pen tip body 1, an axial hole component 2 opened inside the pen tip body 1, and a refill component 3 installed at the bottom end of the pen tip body 1; the refill component 3 includes: a refill sleeve 31 installed at the bottom end of the pen tip body 1, a conductive column 32, a conductive connecting handle 33 and a conductive contact 34 arranged on the inner side of the refill sleeve 31 from top to bottom, and a connecting pin 35 arranged at the top of the conductive column 32; a damping spring 36 is sleeved on the side of the conductive connecting handle 33; the top of the damping spring 36 is fixed to the bottom of the conductive column 32, and the bottom is fixed to the top of the conductive contact 34; the bottom of the conductive connecting handle 33 is fixed to the top of the conductive contact 34, and the length of the damping spring 36 is greater than the length of the conductive connecting handle 33.

[0028] It should be noted that the shaft hole component 2 passes through the inside of the pen body 1 to both ends, and is used to realize a detachable connection between the refill component 3 and the pen shaft; the side of the conductive contact 34 is slidably connected to the inner side of the refill sleeve 31; the shaft hole component 2, the refill sleeve 31, the conductive column 32, the conductive connecting handle 33, the conductive contact 34 and the connecting needle 35 are all coaxially arranged with the pen body 1; the conductive column 32, the conductive connecting handle 33 and the conductive contact 34 are successively clamped upward from the bottom of the refill sleeve 31, and the connecting needle 35 is located at the top of the refill sleeve 31. Through the cooperation of the shaft hole component 2, the refill component 3 is detachably connected to the bottom end of the pen body 1, and the pen shaft of the stylus pen can be detachably connected to the top of the pen body 1. Since the side of the conductive connecting handle 33 is sleeved with a damping spring 36, and the damping spring 36 is The length of the damping spring 36 is greater than that of the conductive connecting handle 33. When not in use, the damping spring 36 serves to disconnect the conductive connecting handle 33 from the conductive column 32. Even if the conductive contact 34 is in direct contact with the screen, the electrical signal will not be transmitted to the conductive contact 34, causing a change in the electric field distribution on the screen, thereby effectively preventing accidental touches. When the user presses down on the pen body, the conductive contact 34 is pressed into the pen core sleeve 31, and squeezes the damping spring 36 to push the conductive connecting handle 33 to contact the conductive column 32. At this time, the electrical signal emitted by the device in the pen body can be transmitted to the capacitive screen through the conductive contact 34, triggering the screen to respond and realize writing. This not only solves the problem of accidental touches, but also realizes the perception of writing force through the extension and retraction action of the conductive contact 34, thereby improving the pressure experience.

[0029] In some embodiments, a stepped structure 4 is provided on the inner side of the refill sleeve 31 , a snap ring 41 is fixed to the bottom end of the conductive column 32 , and the top of the snap ring 41 contacts the bottom of the stepped structure 4 .

[0030] It should be noted that the side of the snap ring 41 has an interference fit with the inner side of the refill sleeve 31; by arranging a stepped structure 4 on the inner side of the refill sleeve 31 and fixing the snap ring 41 at the bottom end of the conductive column 32, the conductive column 32 is installed from the bottom to the top of the refill sleeve 31, and the snap ring 41 contacts the bottom of the stepped structure 4, and the side has an interference fit with the inner side of the refill sleeve 31, which not only ensures the stable installation of the conductive column 32 in the refill sleeve 31, but also provides the necessary friction through the interference fit to prevent the conductive column 32 from loosening or falling off during use.

[0031] In some embodiments, a movable slot 5 is provided at the top of the conductive column 32 , the side of the connecting pin 35 is slidably connected to the inner side of the movable slot 5 , and a reset spring 51 is fixed between the inner bottom of the movable slot 5 and the bottom of the connecting pin 35 .

[0032] It should be noted that when the pen barrel of the stylus pen is detachably connected to the top of the pen tip body 1, the retractable effect formed by the reset spring 51 and the connecting needle 35 can be utilized to form a variable margin when contacting the conductive pen column on the pen barrel. Therefore, when the length of the conductive pen column on the pen barrel fluctuates due to differences in brand or model of the stylus pen barrel, longer or shorter pen barrels can achieve better contact with the connecting needle 35, thereby achieving adaptation to the conductive pen column on pen barrels of different lengths. This not only ensures stable electrical signal transmission, but also avoids the problem of difficult installation of the pen tip and the pen barrel, thereby significantly improving the versatility and compatibility of the pen tip.

[0033] In some embodiments, the conductive post 32 , the conductive connection handle 33 , the conductive contact 34 and the connection pin 35 are all made of flexible conductive material and are used to transmit electrical signals within the stylus for writing.

[0034] It should be noted that by making the conductive column 32, the conductive connecting handle 33, the conductive contact 34 and the connecting needle 35 from flexible conductive materials, firstly, when the conductive contact 34 pushes the conductive connecting handle 33 to connect with one end of the conductive column 32, the connecting needle 35 can transmit the electrical signal in the stylus to the conductive column 32, the conductive connecting handle 33 and the conductive contact 34 in turn, ensuring that the user will not encounter current interruptions during use. 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.

[0035] 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 performance; it has good electromagnetic sealing and water vapor sealing capabilities, and can provide good conductivity under a certain pressure. The use of conductive rubber makes it have good conductivity, reduces the risk of inaccurate touch or damage to the screen due to excessive rigidity of the material, and can provide sufficient damping feeling, allowing users to have a better, more delicate and more realistic writing and drawing experience.

[0036] In some embodiments, the axial hole component 2 includes: a first axial hole 21, a second axial hole 22 and a third axial hole 23, which are sequentially opened inside the pen head body 1 from top to bottom; an internal thread 24 for detachably connecting the pen shaft is opened on the inner side of the first axial hole 21, and the top end of the refill sleeve 31 is installed inside the third axial hole 23.

[0037] It should be noted that the diameter of the first axial hole 21 is larger than that of the second axial hole 22 and the third axial hole 23 respectively; the internal thread 24 provided on the inner side of the first axial hole 21 can be used to detachably connect the pen holder of the stylus pen to the inner side of the first axial hole 21 through the cooperation of the internal thread 24. When the user needs to replace the pen head assembly or the pen holder separately, it is convenient to disassemble and install, thereby improving the convenience during use and the user's personalized replacement; the second axial hole 22 is used to connect the first axial hole 21 and the third axial hole 23. If the conductive pen column at the bottom end of the pen holder needs to be docked with one end of the connecting needle 35, it can pass through the second axial hole 22 through the first axial hole 21, thereby docking with the connecting needle 35 in the third axial hole 23 to realize the transmission of charge.

[0038] In some embodiments, the side surface of the refill sleeve 31 close to the top is threadedly connected to the inner side of the third shaft hole 23 .

[0039] It should be noted that when the refill component 3 is connected and installed to one end of the nib body 1, the top end of the refill sleeve 31 is screwed into the inner side of the third axial hole 23, so that the refill sleeve 31 and the third axial hole 23 can be threadedly connected, thereby completing the connection and installation of the refill component 3. This not only ensures the firm installation of the refill component 3 in the nib body 1, but also provides a convenient disassembly method. At the same time, the tightness of the threaded connection also effectively prevents external factors such as dust and moisture from invading the interior of the nib, thereby protecting the electrical performance and service life of the component.

[0040] The utility model provides a touch pen (not shown in the figure), comprising a pen head assembly as described above, wherein the bottom end of the pen shaft of the touch pen is connected to the pen head body 1 through an axis hole component 2.

[0041] It should be noted that the conductive pen post at the bottom end of the pen barrel contacts the top end of the connecting needle 35 in the refill component 3 to realize the transmission of electric charge and ensure the stable transmission of electrical signals.

[0042] When the present invention is used, when the stylus is not in use, the damping spring 36 remains in an extended state, disconnecting the conductive connecting handle 33 from the conductive column 32. Even if the conductive contact 34 is in direct contact with the screen, the electrical signal cannot be transmitted to the conductive contact 34, effectively preventing accidental touches. When the user presses down on the pen body, the conductive contact 34 is pressed into the pen core sleeve 31 and squeezes the damping spring 36, pushing the conductive connecting handle 33 to contact the conductive column 32. At this time, the electrical signal emitted by the device in the pen body can be transmitted to the capacitive screen through the conductive contact 34, triggering the screen to respond and achieve writing. At the same time, the telescopic action of the conductive contact 34 can also realize the perception of writing force and enhance the pressure experience. The pen shaft is detachably connected to the pen core component 3 through the shaft hole component 2 inside the pen body 1, which is convenient for users to replace the pen head assembly or pen shaft, and the connecting needle 35 in the pen core component 3 is in contact with the conductive pen column at the bottom of the pen shaft to achieve stable transmission of charge.
