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 with high versatility. 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] In the working principle of a stylus, capacitance change is the key factor in its recognition of touch input. When the tip of the stylus approaches or touches the capacitive screen, it causes the electric field distribution on the screen to change, which is then recognized as touch input by the sensor inside the screen.
[0004] 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; after long-term use, the pen tip will inevitably wear out the contact or pen tip, and when excessively worn, the sensitivity of use often decreases. In the existing technology, a detachable pen tip design is often used to replace the worn pen tip separately. However, even for styluses of the same brand, due to slight differences in the production process, the length of the conductive pen column in the pen barrel of the same model of stylus may also fluctuate within a certain range, which may easily lead to the conductive contact failing to effectively contact the conductive pen column, or the pen tip being difficult to install, reducing the versatility of the pen tip. Summary of the Invention
[0005] The utility model overcomes the shortcomings of the prior art and provides a touch pen head assembly and a touch pen with high versatility.
[0006] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a stylus pen tip assembly and a stylus pen with high versatility, comprising: a tip body, an axial hole component provided inside the tip body, and a refill component installed at the bottom end of the tip body;
[0007] The shaft hole component passes through the interior of the pen head body to both ends, and the shaft hole component is used to achieve a detachable connection between the pen core component and the pen body;
[0008] The refill component includes: a refill sleeve installed at the bottom end of the pen head body, a conductive column and a conductive connecting handle that are sequentially clamped on the inner side of the refill sleeve from top to bottom, and a conductive contact fixed at the bottom end of the conductive connecting handle; a connecting pin is inserted at the top end of the conductive column, and a damping spring is fixed between the bottom end of the connecting pin and the inner side of the conductive column.
[0009] In a preferred embodiment of the present invention, the inner side of the refill sleeve is a stepped structure, a clamping ring is fixed to the bottom end of the conductive column, the top of the clamping ring is clamped with the stepped structure, the inner diameter of the refill sleeve near the bottom end is the same as the diameter of the clamping ring, and the inner diameter of the refill sleeve near the top end is smaller than the diameter of the clamping ring.
[0010] In a preferred embodiment of the present invention, the side surface of the conductive connecting handle is interference-fitted with the inner side of the refill sleeve near the bottom end.
[0011] 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.
[0012] 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 detachably connecting to the pen shaft, and the top end of the pen core sleeve is installed inside the third axial hole.
[0013] 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.
[0014] In a preferred embodiment of the present invention, the side surface of the refill sleeve close to the top end is interference fit with the inner side of the third shaft 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] In a preferred embodiment of the present invention, the refill sleeve, the conductive column, the conductive connecting handle and the connecting needle are all coaxially arranged with the pen head body.
[0017] 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.
[0018] The present invention solves the defects in the background technology and has the following beneficial effects:
[0019] (1) The present invention provides a stylus pen tip assembly and a stylus pen with high versatility. The pen tip assembly is composed of a pen tip body, an axial hole component and a refill component. With the cooperation of a refill sleeve, a conductive column, a conductive connecting handle, a conductive contact, a connecting needle and a damping spring, a variable margin is formed when contacting the conductive column on the pen barrel. Therefore, when the length of the conductive column on the stylus pen barrel fluctuates due to differences in brand or model, longer or shorter pen barrels can achieve better contact with the connecting needle, thereby achieving adaptation to the conductive columns on pen barrels of different lengths. This not only ensures stable electrical signal transmission, but also avoids the problem of difficulty in installing the pen tip and the pen barrel, thereby significantly improving the versatility and compatibility of the pen tip.

During use, if a certain part of the pen core component, the pen head body and the pen holder is used or bumped many times, causing the contact and other parts to be worn, it is only necessary to disassemble and replace the worn part separately, thereby increasing the life of the touch pen during use and reducing the cost of use.

[0030] It should be noted that the refill sleeve 31, the conductive column 32, the conductive connecting handle 33 and the connecting needle 35 are all coaxially arranged with the pen body 1; the bottom end of the conductive column 32 contacts the top end of the conductive connecting handle 33, the conductive contact 34 is located at the bottom end of the refill sleeve 31, and the top end of the connecting needle 35 is located at the top end of the refill sleeve 31; the conductive column 32 and the conductive connecting handle 33 are sequentially clamped upward from the bottom of the refill sleeve 31, and the connecting needle 35 is located at the top end of the refill sleeve 31, and the conductive contact 34 is located at the bottom end of the refill sleeve 31, and the refill component 3 can be detachably connected to the bottom end of the pen body 1 through the cooperation of the shaft hole component 2, and can The pen holder of the stylus pen can be detachably connected to the top of the pen tip body 1, and the retractable effect formed by the damping spring 36 and the connecting needle 35 is used to form a variable margin when contacting the conductive pen column on the pen holder. Therefore, when the length of the conductive pen column on the stylus pen holder fluctuates due to differences in brand or model, longer or shorter pen holders can achieve better contact with the connecting needle 35, thereby achieving adaptation to the conductive pen columns on pen holders of different lengths, thereby ensuring stable electrical signal transmission, avoiding the problem of difficult installation of the pen tip and the pen holder, and significantly improving the versatility and compatibility of the pen tip.
[0031] like Figure 3As shown, in this embodiment, the inner side of the refill sleeve 31 is a stepped structure, and a snap ring 4 is fixed to the bottom end of the conductive column 32. The top of the snap ring 4 is engaged with the stepped structure. The inner diameter of the refill sleeve 31 near the bottom end is the same as the diameter of the snap ring 4, and the inner diameter of the refill sleeve 31 near the top end is smaller than the diameter of the snap ring 4. Through the arrangement of the snap ring 4, since the inner side of the refill sleeve 31 is a stepped structure and the top of the snap ring 4 is engaged with the stepped structure, the conductive column 32 can be inserted through the bottom end of the refill sleeve 31, so that the conductive column 32 is stably engaged on the stepped structure inside the refill sleeve 31 by the snap ring 4, thereby improving the connection reliability between the conductive column 32 and the refill sleeve 31.
[0032] In this embodiment, the side of the conductive connecting handle 33 is interference fit with the inner side of the refill sleeve 31 near the bottom end; by making the side of the conductive connecting handle 33 interference fit with the inner side of the refill sleeve 31 near the bottom end, the conductive column 32 is first passed upward from the bottom of the refill sleeve 31 and clamped on the inner wall of the refill sleeve 31, and then the side of the conductive connecting handle 33 is interference fit on the inner side of the refill sleeve 31, and after contacting with the bottom of the conductive column 32, it can ensure that it is not easy to fall off during use, thereby improving the reliability and detachability of the stylus.

[0036] 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.

The conductive pen column on the pen body passes through the first shaft hole 21 and the second shaft hole 22, and docks with the connecting pin 35 in the third shaft hole 23. The connecting pin 35 is pressed down to squeeze the damping spring 36 at the bottom of the connecting pin 35 to achieve better contact and adapt to the conductive pen column on pens 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 body, significantly improving the versatility and compatibility of the pen tip.
