Referring to fig. 3 and 4, wherein fig. 4 is a partial enlarged view of fig. 3, in the present embodiment, the pen body 13 of the hollow pen tube 10 is a conductive pen body, for example, the pen body 13 may be made of metal or conductive plastic, and the second electrode bridge 60 may be the above-mentioned pen body 13 and has a conductive function. Since the thin film layer 52 of the first electrode bridge 50 is blocked between the conductive circuit 51 and the pen body 13, the first electrode bridge 50 and the second electrode bridge 60 are insulated from each other without short circuit.

The secondary circuit board 30 includes a second conductive element 32 (such as a metal spring probe, a metal spring, or a conductive rubber), and the second conductive element 32 is electrically connected to the second conductive part 31 through the secondary circuit board 30. The second guiding element 32 can directly contact the pen body 13 to conduct the second electrode 44 of the battery 40 to the pen body 13.

The second conductive element 32 of the secondary circuit board 30 is in contact with the inner ring 161, and the pen body 13 is sleeved on the outer ring 162, so that the second conductive element 32 of the secondary circuit board 30 can be electrically connected to the pen body 13 through the second electrode conductive element 16, so as to conduct the second electrode 44 of the battery 40 to the direction of the main circuit board 20.

Therefore, the power of the two circuit boards (i.e., the main circuit board 20 and the sub circuit board 30) at two opposite ends of the stylus pen device 1 can be provided by using a single battery, so that two batteries are not needed to supply power to the two circuit boards respectively, and the overall length of the stylus pen device 1 can be reduced. Furthermore, compared with the prior art that two batteries are respectively used for power supply on two circuit boards, when the batteries are insufficient in power, a user does not need to judge which battery is out of power, so that the problem of battery replacement errors is avoided, and the use trouble is reduced.

As further shown in fig. 2 and 3, in an embodiment, the pen cap 14 may be a plastic pen cap, and the secondary circuit board 30 includes a wireless communication module (such as a WiFi module, a bluetooth module, an 802.11 module, or a ZigBee module), for example, a circuit board without wireless communication function (such as the main circuit board 20) may be disposed inside the metal pen body 13. A circuit board with wireless communication function (such as the sub circuit board 30) can be disposed inside the plastic pen cap 14, so that the radio waves emitted by the circuit board are not shielded or interfered. Of course, if there is no consideration of wireless communication, the hollow pen tube 10 may be made of metal material as a whole, so that the stylus device 1 has better structural strength and the whole appearance is more consistent.

As shown in fig. 2, 4 and 5, wherein fig. 5 is a cross-sectional view of fig. 4 taken along line 5-5, in one embodiment, an end of the thin film layer 52 of the first electrode bridge 50 near the secondary circuit board 30 is covered outside the conductive body 151, so that the conductive trace 51 can be electrically connected to the conductive body 151. Here, the width of the thin film layer 52 of the first electrode bridge 50 near the end of the secondary circuit board 30 (hereinafter, the covered end 521) is greater than the width of the thin film layer 52 of the first electrode bridge 50 near the end of the primary circuit board 20 (shown in detail in fig. 2), that is, the thin film layer 52 of the first electrode bridge 50 is generally T-shaped, thus, the covered end 521 of the thin film layer 52 of the first electrode bridge 50 can be curled into a circular or semicircular shape and covered outside the conductive body 151 (shown in detail in fig. 5), so that the conductive body 151 can fully contact the conductive circuit 51 on the surface of the thin film layer 52, so that the pen cap 14 can be assembled, the problem of directionality is not required to be considered, that is, no matter which direction the pen cap 14 is installed into the pen body 13, the conductive body 151 can be covered by the thin film layer 52 and electrically contacted with the conductive circuit 51, so as to increase the convenience of use and assembly and the reliability of the product. In some embodiments, the overall width of thin film layer 52 of first electrode bridge 50 can be the same, such as where the overall width of thin film layer 52 is less than the width of electrical conductor 151 and contacts only a localized area of the outer periphery of electrical conductor 151, or where the overall width of thin film layer 52 is greater than the width of electrical conductor 151 and can be crimped over all or a substantial portion of the outer periphery of electrical conductor 151.

However, the embodiments of the first electrode bridge 50 and the second electrode bridge 60 are not limited to the foregoing embodiments, and in some embodiments, the first electrode bridge 50 may be a conductive pen body, and the second electrode bridge 60 is a thin film line disposed on the wall of the hollow pen tube 10. Alternatively, as shown in FIG. 6, it is a partial enlarged cross-sectional view of another embodiment of the stylus apparatus of the present application. The difference between the present embodiment and the embodiment of fig. 3 is that the first electrode bridge member 50 and the second electrode bridge member 60 of the stylus device 1A are film lines respectively attached to the inner wall of the hollow pen tube 10, in other words, the second electrode bridge member 60 and the first electrode bridge member 50 have similar structures, for example, the second electrode bridge member 60 also includes a film layer and a conductive circuit on the surface of the film layer, and one end of the second electrode bridge member 60 is connected to the second electrode conductive member 16, and the other end is connected to the other first lead member 22A of the main circuit board 20, so that the second electrode 44 of the battery 40 can be also conducted to the main circuit board 20.

Further, in other embodiments, the body 13, the cap 14 and the tip 18 of the hollow pen barrel 10 can be made of non-conductive materials, for example, the body 13, the cap 14 and the tip 18 of the hollow pen barrel 10 are made of plastic materials, the first electrode bridge 50 and the second electrode bridge 60 are conductive circuits (such as conductive sheets, conductive wires or thin film circuit boards) respectively attached to the inner wall of the hollow pen barrel 10, one end of the first electrode bridge 50 is connected or soldered to the main circuit board 20, the other end of the first electrode bridge is connected or soldered to the sub-circuit board 30, one end of the second electrode bridge 60 is connected or soldered to the sub-circuit board 30, and the other end of the second electrode bridge is connected or soldered to the main circuit board 20, so that the effects of using a single battery to provide power for the two circuit boards and reducing. Thus, the first electrode conductor 15 and the second electrode conductor 16 do not need to be additionally arranged, thereby saving materials and manufacturing processes. Furthermore, since the pen body 13, the pen cap 14 and the pen head 18 of the hollow pen tube 10 are made of plastic materials, the overall appearance is more consistent, and the degree of freedom in the arrangement of the main circuit board 20 and the auxiliary circuit board 30 is increased. For example, the main circuit board 20 or the sub circuit board 30 can be selectively configured as a circuit board with wireless transmission function, and the wireless signal can be transmitted without being shielded or interfered, so that the main circuit board 20 or the sub circuit board 30 is not limited in selection. In addition, in some embodiments, the battery 40 may also be disposed on the same side of the main circuit board 20 and the sub circuit board 30, and is not necessarily disposed between the main circuit board 20 and the sub circuit board 30, which is omitted here.
