Referring to FIG. 1 to FIG. 4 , the stylus pen includes a pen tip fixing structure, and the pen head fixing structure includes a pen tip housing 1 , a touch component 2 , and a pen body shell 3 , and the touch component 2 includes a pen tip 21 connected to one end of the fixed case 22, and a pen tip 21 extending from the head of the nib case 1, the fixed case 22 being embedded in the nib case 1 and with the nib case 1 When the phase is engaged, the nib shell 1 and the pen body 3 are also engaged. Based on the structure, the pen tip bar 21 of the touch component 2 can be protruded from the head through hole of the pen tip housing 1 at the time of installation, and the fixing case 22 is embedded in the pen tip housing 1 to be engaged with the pen tip housing 1. So that the touch component 2 and the nib shell 1 are assembled into an integral pen tip assembly 120, and then the pen tip assembly 120 is assembled with the head of the pen body shell 3, specifically, the nib shell 1 and the pen body shell 3 are assembled. The card is connected to each other, so that the fixed installation of the entire pen head can be completed. Therefore, the pen head fixing structure is easy to assemble, and the mutual clamping between the components after assembly makes the connection structure very reliable and has high reliability.

The fixing shell 22 of the embodiment is provided with a card protrusion 2233. The nib shell 1 is provided with a card hole 11 matched with the card protrusion 2233, thereby enabling the locking between the fixing shell 22 and the nib shell 1. In turn, the touch component 2 and the nib shell 1 can be assembled into the above-described pen tip assembly 120. In order to further improve the connection between the fixed case 22 and the nib case 1, and to facilitate the assembly connection between the fixed case 22 and the nib case 1, in the present embodiment, the fixed case 22 is further disposed toward the two faces. The elastic buckle 2234 is disposed in the front end direction, and the inside of the nib shell 1 is provided with a card slot (not shown) that cooperates with the elastic buckle 2234. Specifically, the elastic buckle 2234 includes two opposite ends. The hook is provided with a resilient gap between the two hooks, and the slot can be a tapered slot. In the embodiment, the nib shell 1 is further provided with an annular protrusion 12, and the inner wall of the pen body shell 3 is provided with an annular groove 31 matched with the annular protrusion 12, thereby realizing the nib shell 1 and the pen The snapping between the body shells 3, in turn, enables the connection between the entire pen assembly 120 and the pen body. In addition, the battery body 4 is mounted in the pen body case 3 of the embodiment, and the battery 4 is disposed near the head of the pen body case 3. The pen tip housing 1 is provided with a first step 13, and the head of the pen body case 3 is provided with The first step 13 corresponds to the second step 32 that is matched, so that the mutual abutment of the two steps can reduce the impact on the battery 4 when the tip of the stylus is touched.

Further, the touch control assembly 2 of the present embodiment includes an electromagnetic control board 24, an induction coil 25, and a telescopic bracket 26. The telescopic bracket 26 is disposed in the fixed housing 22, and the nib rod 21 is connected to the telescopic bracket 26, and the induction coil 25 is wound. The electromagnetic control board 24 is mounted on the fixed housing 22, and the induction coil 25 and the electromagnetic control board 24 are electrically connected. Therefore, when the pen tip 21 is written or touched on the interactive smart tablet, the electromagnetic film on the interactive smart tablet is sensed with the induction coil 25, so that the display of the written content or the touch can be realized on the interactive smart tablet. Operation, and if the writing force is different, the degree of expansion and contraction of the telescopic bracket 26 is different, so that the relative distance between the induction coil 25 and the interactive smart plate changes, and the electromagnetic film on the interactive smart plate senses the change. After that, the thickness of the written stroke displayed on the tablet is also changed accordingly, so that the stylus can control the thickness of the stroke written on the interactive smart tablet. The electromagnetic control board 24 is used to control the induced current of the induction coil 25. In addition, through the small expansion and contraction of the telescopic bracket 26, it is also beneficial to improve the touch feel and writing feel of the stylus on the interactive smart tablet.

The fixed case 22 of the present embodiment includes a front convex housing 222 and a rear cover housing 223. The front convex housing 222 and the rear cover housing 223 are connected to each other and define an inner cavity, and the telescopic bracket 26 is disposed inside. In the cavity, the pen tip 21 is detachably connected to the telescopic bracket 26, and the pen tip 21 protrudes from the front convex housing 222, and the induction coil 25 is fixedly sleeved on the outer wall of the front convex housing 222. 222 is essentially a coil holder. Specifically, the telescopic bracket 26 includes a nib bracket 261 and a resilient block 262. The nib bracket 261 is a strip bracket. The nib bar 21 is detachably engaged with one end of the nib bracket 261. The elastic block 262 is disposed at the other end of the nib bracket 261. a limiting hole is formed in the shell wall of the rear cover shell 223, and the elastic block 262 abuts in the limiting hole; thereby, when the nib bar 21 is pressed on the interactive smart plate, the nib bar 21 is pressed and transmitted to the nib The bracket 261 and the elastic block 262 cause the elastic block 262 to be compressed and contracted, so that the entire nib support 261 and the nib bar 21 are also contracted toward the pen body, thereby causing the distance between the induction coil 25 and the interactive smart plate to change. Moreover, the force of the pen tip bar 21 on the interactive smart plate is different, and the degree of the above-mentioned contraction is also different, and the degree of variation between the distance between the induction coil 25 and the interactive smart plate is also different, so that the electromagnetic film of the interactive smart plate is After sensing this change, the thickness of the written strokes will be different. It should be noted that the telescopic bracket 26 of the present embodiment is composed of an elastic block 262 and a nib bracket 261. The nib bracket 261 can be a rigid plastic bracket or an elastic bracket, and the elastic block 262 can be an elastic plastic member. The elastic action of the elastic block 262 can realize the expansion and contraction of the nib support 261, and also realize the expansion and contraction of the telescopic support 26. Here, the extent of the expansion and contraction is small, and mainly by the elastic deformation of the elastic block 262. caused.

In addition, the rear cover housing 223 includes a main body shell portion 2231 and an extended shell portion 2232. The main body shell portion 2231 has a cylindrical shell structure, and the extended shell portion 2232 has a semicircular shell structure. The card protrusion 2233 is disposed on the main body shell portion. The elastic buckle 2234 is disposed on the front side of the cylindrical portion 2231 at the front end of the main body casing portion 2231 so as to achieve a reliable connection between the fixed casing 22 and the nib casing 1; and the electromagnetic control panel 24 is mounted on the extension casing portion 2232. And it is engaged in the U-shaped groove at the front end of the battery 4, thereby making the connection installation more reliable. It should also be noted here that the main body shell portion 2231 and the extension shell portion 2232 of the present embodiment may be integrally formed to facilitate manufacturing.

In summary, the tip fixing structure of the stylus of the embodiment is easy to assemble, and the mutual locking between the components after assembly makes the connecting structure very reliable and has high reliability. In addition, the stylus of the embodiment can be better in touch and writing on the interactive smart tablet, and the stylus can control the thickness of the writing stroke on the interactive smart tablet, thereby facilitating a good user experience. .
