Abstract
Description
Technical Field
[0001] This utility model relates to a touch device, and more particularly to a touch device with a detachable battery module. Background Technology
[0002] An existing stylus typically encapsulates a lithium battery within a pen casing, thereby powering the stylus located within the casing. The lithium battery is then charged via an external power source through a built-in charging port, a spring-loaded contact, or a wireless charging coil.
[0003] However, because the lithium battery is encapsulated within the pen's casing, if the battery's lifespan decreases and becomes insufficient, the entire existing stylus needs to be replaced, which is quite environmentally unfriendly. Furthermore, the existing stylus does not comply with EU regulations requiring that batteries in household appliances be removable and replaceable by the end user. Clearly, the existing stylus is still awaiting improvements from researchers in the relevant field. Utility Model Content
[0004] The purpose of this invention is to provide a touch device with a detachable battery module that can overcome the above-mentioned shortcomings.
[0005] This utility model relates to a touch device with a detachable battery module, comprising a stylus module and a detachable battery module. The stylus module includes a pen body shell defining a pen tip opening and a pen body opening, and a touch component located within the pen body shell. The touch component has a bracket, a pen tip disposed on the bracket and exposed in the pen tip opening, a first interface fixed to the bracket on the side opposite to the pen tip and adjacent to the pen body opening, and a touch circuit electrically connected to the first interface. The touch circuit is used to generate a pressure-sensitive signal corresponding to the force applied to the pen tip. The detachable battery module includes a battery shell, a built-in battery installed in the battery shell, a second interface fixed to the battery shell, and a protection circuit electrically connecting the built-in battery and the second interface. The second interface is used to insert into the first interface for electrical connection to the first interface.
[0006] The touch device with a detachable battery module of this utility model has a first interface as a USB-C socket and a second interface as a USB-C plug.
[0007] The touch device with a detachable battery module of this utility model has a second interface exposed in the battery casing. The second interface is used to extend into the pen body opening and insert the first interface to electrically connect to the first interface.
[0008] The touch device with a detachable battery module described in this utility model has a built-in lithium polymer battery.
[0009] The touch device with a detachable battery module described in this utility model has a pen body shell composed of a circular arc segment and a flat segment.
[0010] The present invention relates to a touch device with a detachable battery module. The battery casing is composed of a battery arc segment, a battery flat segment, and a transparent lens. The shape of the battery arc segment corresponds to the shape of the pen body arc segment and defines an indicator hole. The shape of the battery flat segment corresponds to the shape of the pen body flat segment. The transparent lens is fixedly disposed on the indicator hole.
[0011] The present invention relates to a touch device with a detachable battery module.

[0021] See Figure 1 and Figure 2 One embodiment of the present invention is a touch device with a detachable battery module, comprising a stylus module 1 and a detachable battery module 2.
[0022] See Figures 3 to 5 The stylus module 1 includes a pen body shell 11 that defines a pen tip opening 111 and a pen body opening 112, and a touch component 12 located within the pen body shell 11.
[0023] The pen body shell 11 is composed of an arc segment 113 and a flat segment 114. In other words, the outer contour of the pen body shell 11 is substantially non-elliptical, thereby preventing rolling.
[0024] The touch component 12 includes a bracket 121, a pen tip 122 disposed on the bracket 121 and exposed in the pen tip opening 111, a first interface 123 fixed to the bracket 121 on the side opposite to the pen tip 122 and adjacent to the pen body opening 112, and a touch circuit 124 electrically connected to the first interface 123. The touch circuit 124 is used to generate a pressure-sensitive signal corresponding to the force applied to the pen tip 122. In this embodiment, the first interface 123 is a USB-C socket, and the touch circuit 124 is an assembly circuit board.
[0025] See Figure 3 , Figure 6 and Figure 7 The detachable battery module 2 includes a battery casing 21, a built-in battery 22 installed inside the battery casing 21, a second interface 23 fixed to and exposed on the battery casing 21, and a protection circuit 24 electrically connecting the built-in battery 22 and the second interface 23. In this embodiment, the second interface 23 is a USB-C plug, and the built-in battery 22 is a lithium polymer battery.
[0026] The battery casing 21 is composed of a battery arc segment 211, a battery flat segment 212 and a transparent lens 213. The shape of the battery arc segment 211 corresponds to the shape of the pen body arc segment 113 and defines an indicator hole 214. The shape of the battery flat segment 212 corresponds to the shape of the pen body flat segment 114. The transparent lens 213 is fixedly disposed in the indicator hole 214.
[0027] See Figure 7 The second interface 23 has a first charging pin group 231 and a second charging pin group 233. The first charging pin group 231 has two first charging pins 232. The second charging pin group 233 has two second charging pins 234. In this embodiment, the first charging pins 232 correspond to A4 and A9 of the USB-C interface standard, respectively. The second charging pins 234 correspond to B4 and B9 of the USB-C interface standard, respectively.
[0028] The protection circuit 24 includes a protection chip 241 electrically connected to the second interface 23 and the built-in battery 22, a reverse protection diode 246, an indicator LED 247, and a setting resistor 248. The protection chip 241 has a power pin 242 electrically connected to the first charging pin group 231, an indicator pin 243 electrically connected to the indicator LED 247, a working pin 244 electrically connected to the built-in battery 22, and a setting pin 245 electrically connected to the setting resistor 248. The positive terminal of the reverse protection diode 246 is electrically connected to the working pin 244 and the built-in battery 22, and the negative terminal of the reverse protection diode 246 is electrically connected to the second charging pin group 233. The position of the indicator LED 247 corresponds to the transparent lens 213 (e.g., ...). Figure 6 (As shown).
[0029] In addition, according to the predetermined specifications of the protection chip 241, different values of the indicator LED 247 and the setting resistor 248 need to be selected to control the charging current supplied to the built-in battery 22 by the working pin 244, and to control the light emission mode of the indicator LED 247. Adjusting the values of the indicator LED 247 and the setting resistor 248 is a detail that can be easily deduced by those skilled in the art, or can be easily replaced by existing methods, and will not be elaborated here.
[0030] It is worth mentioning that, due to the design of the protection circuit 24, the first interface 123 and the second interface 23 cannot be reversed according to the USB-C interface standard.
[0031] The following describes the operating mode of the separate battery module 2.
[0032] During actual charging, the second interface 23 is used to connect an external power source (e.g., a power bank supporting the USB-C interface standard, a USB-C socket plugged into an AC outlet, etc.). The current received by the first charging pin group 231 is blocked by the anti-reverse diode 246 and will not charge the built-in battery 22. Instead, the current received by the second charging pin group 233 charges the built-in battery 22 through the protection chip 241, ensuring the reliability of charging the built-in battery 22.
[0033] In actual power supply, the second interface 23 is used to insert the first interface 123 to electrically connect the first interface 123. More precisely, the second interface 23 is used to extend into the pen body opening 112 and insert the first interface 123 to electrically connect the first interface 123. In this way, the built-in battery 22 can supply power to the stylus module 1 via the first charging pin group 231.
[0034] In summary, this embodiment has the following advantages:
[0035] (i) By configuring the second interface 23 of the detachable battery module 2 and the first interface 123 of the stylus module 1, the second interface 23 can be detachably disposed on the first interface 123. This not only ensures repeated plugging and unplugging between the first interface 123 and the second interface 23, but also achieves a detachable design between the detachable battery module 2 and the stylus module 1, thereby providing the effect of easy replacement of the detachable battery module 2.
[0036] (ii) By making the first interface 123 adopt a USB-C socket and the second interface 23 adopt a USB-C plug, the USB-C standard is met, thereby improving the convenience of charging the built-in battery 22 via the second interface 23.
[0037] (iii) By having the pen body shell 11 be composed of the pen body arc segment 113 and the pen body flat segment 114, the stability of the pen body shell 11 when placed flat is improved.
[0038] (iv) By making the battery casing 21 composed of the battery arc segment 211 and the battery flat segment 212, it is made to match the shape of the pen body casing 11, so as to ensure that the second interface 23 will not be misaligned or reversed when the first interface 123 is inserted.
[0039] Therefore, the touch control device with a detachable battery module of this utility model can indeed achieve the purpose of this utility model.
[0040] However, the above description is merely an embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification of this utility model shall still fall within the scope of this utility model patent.
