Description

Technical Field

[0001] This utility model relates to the field of capacitive pen technology, and in particular to a capacitive pen with a snap-fit ​​structure. Background Technology

[0002] With the rapid development of technology, capacitive touchscreen devices such as mobile phones, tablets, and computers are becoming increasingly widespread in daily life. Consequently, the demand for capacitive pens that enable writing on capacitive screens is also rising. A capacitive pen is a pen made of conductive materials that possess conductive properties, used to touch capacitive screens to complete human-computer interaction. It is an auxiliary device that uses conductive materials to mimic the human body for human-computer interaction. The emergence of capacitive pens has provided people with greater convenience, allowing them to write freely on capacitive screens like ordinary pens. In existing technologies, capacitive pens typically use magnetic attraction to achieve detachment and engagement, which is relatively expensive and does not produce sound when engaged, thus failing to provide audible feedback to the user. Therefore, designing a capacitive pen that provides audible feedback when engaged while remaining inexpensive is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] Therefore, it is necessary to provide a capacitive pen with a snap-fit ​​structure, in which the cap assembly moves relative to the pen tube assembly and makes a sound due to the snap-fit ​​structure, providing sound feedback to the user and improving the user experience.

[0004] A capacitive pen with a snap-fit ​​structure includes a pen tube assembly and a pen cap assembly. The pen cap assembly is located at the rear end of the pen tube assembly. The pen tube assembly includes a pen tube and a support rear cover. A first receiving cavity is formed in the pen tube. The support rear cover is fixed in the first receiving cavity.

[0005] The pen cap assembly includes a pen cap and a pen cap bracket. The pen cap bracket is fixed in the pen cap and is sleeved and connected to the rear cover of the bracket. The pen cap bracket has a third snap-fit ​​position. The pen cap bracket can slide relative to the rear cover of the bracket along the axial direction so that the third snap-fit ​​position is engaged with the first snap-fit ​​position or the second snap-fit ​​position. The second snap-fit ​​position is closer to the rear end of the pen tube assembly than the first snap-fit ​​position.

[0006] In the capacitive pen with a snap-fit ​​structure provided in this application, when a user needs to install the pen cap assembly onto the pen tube assembly, the user moves the pen cap assembly towards the pen tube assembly along the axial direction of the capacitive pen. At this time, the third snap-fit ​​position first engages with the first snap-fit ​​position. Continuing to move the pen cap assembly, the third snap-fit ​​position disengages from the first snap-fit ​​position, and further, the third snap-fit ​​position engages with the second snap-fit ​​position. During the above process, the snap-fit ​​structure produces a sound as the pen cap assembly moves relative to the pen tube assembly, providing audio feedback to the user and improving the user experience.

The battery is electrically connected to the terminal block through the motherboard, and the terminal block is located between the first latching position and the second latching position. When the pen cap bracket slides along the axial direction to engage the third latching position with the second latching position, a gap space is formed between the pen cap and the pen tube, and the terminal block is exposed in the gap space.

[0013] In one embodiment, the rear end of the pen tube forms a clearance groove along the axial direction, the terminal block is located below the clearance groove, and the pen cap is provided with a clip; when the pen cap bracket slides along the axial direction to engage the third snap-fit ​​position with the first snap-fit ​​position, the clip moves above the clearance groove to cover the terminal block; when the pen cap bracket slides along the axial direction to engage the third snap-fit ​​position with the second snap-fit ​​position, the clip moves away from the clearance groove to expose the terminal block.

The pen tip component includes a transmitter located at the front end of the pen tube. The battery is electrically connected to the wireless charging component, the transmitter, and the vibration component respectively through the motherboard.

[0029] With the rapid development of technology, capacitive touchscreen devices such as mobile phones, tablets, and computers are becoming increasingly widespread in daily life. Consequently, the demand for capacitive pens that enable writing on capacitive screens is also rising. A capacitive pen is a pen made of conductive materials that possess conductive properties, used to touch capacitive screens to complete human-computer interaction. It is an auxiliary device that uses conductive materials to mimic the human body for human-computer interaction. The emergence of capacitive pens has provided people with greater convenience, allowing them to write freely on capacitive screens like ordinary pens. In existing technologies, capacitive pens typically use magnetic attraction to achieve detachment and engagement, which is relatively expensive and does not produce sound when engaged, thus failing to provide audible feedback to the user. Therefore, designing a capacitive pen that provides audible feedback when engaged while remaining inexpensive is a technical problem that urgently needs to be solved by those skilled in the art.

[0030] See Figures 1 to 7 To address the aforementioned issues, this application provides a capacitive pen 10 with a snap-fit ​​structure, comprising a pen tube assembly 20 and a pen cap assembly 30. The pen cap assembly 30 is located at the rear end of the pen tube assembly 20. The pen tube assembly 20 includes a pen tube 21 and a support rear cover 22. A first receiving cavity 211 is formed in the pen tube 21, and the support rear cover 22 is fixed in the first receiving cavity 211. The support rear cover 22 is axially spaced with a first snap-fit ​​position 221 and a second snap-fit ​​position 222. The pen cap assembly 30 includes a pen cap 31 and a pen cap support 32. The pen cap support 32 is fixed in the pen cap 31 and sleeved with the support rear cover 22. The pen cap support 32 is provided with a third snap-fit ​​position 321, and the pen cap support 32 can slide axially relative to the support rear cover 22 so that the third snap-fit ​​position 321 engages with the first snap-fit ​​position 221 or the second snap-fit ​​position 222. The second snap-fit ​​position 222 is closer to the rear end of the pen tube assembly 20 than the first snap-fit ​​position 221.

[0031] See Figures 1 to 7The capacitive pen 10 with a snap-fit ​​structure includes a pen tube assembly 20 and a pen cap assembly 30, with the pen cap assembly 30 located at the rear end of the pen tube assembly 20. The pen tube assembly 20 includes a pen tube 21 and a support back cover 22. The pen tube 21 forms part of the outer shell structure of the capacitive pen. In some embodiments, the pen tube 21 can be made of metal, which has high hardness and a long service life, suitable for scenarios requiring frequent writing or drawing. Alternatively, the pen tube 21 can be made of rubber, which is soft, comfortable to use, and effectively protects the touchscreen. A first receiving cavity 211 is formed in the pen tube 21, and the support back cover 22 is fixed in the first receiving cavity 211 to ensure a relatively stable position for the support back cover 22. The pen cap assembly 30 includes a pen cap 31 and a pen cap bracket 32. The pen cap bracket 32 ​​is fixed within the pen cap 31 and is sleeved onto the bracket back cover 22 to achieve a compact structure. Specifically, the bracket back cover 22 has a first latching position 221 and a second latching position 222 spaced apart axially, and the pen cap bracket 32 ​​has a third latching position 321. The first latching position 221 and the third latching position 321 are adapted to achieve a fastening, and the second latching position 222 and the third latching position 321 are adapted to achieve a fastening. In some embodiments, when the pen cap bracket 32 ​​slides axially relative to the bracket back cover 22, the third latching position 321 can engage with the first latching position 221. In other embodiments, when the pen cap bracket 32 ​​slides axially relative to the bracket back cover 22, the third latching position 321 can engage with the second latching position 222. In some embodiments, the second latching position 222 is closer to the rear end of the pen tube assembly 20 than the first latching position 221. Specifically, when the user needs to install the pen cap 31 onto the pen tube assembly 20, the user moves the pen cap assembly 30 towards the pen tube assembly 20 along the axial direction of the capacitive pen. At this time, the third latching position 321 first engages with the first latching position 221. Continuing to move the pen cap bracket 32, the third latching position 321 disengages from the first latching position 221, and further, the third latching position 321 engages with the second latching position 222. During the above process, the pen cap assembly 30 can produce a sound due to the latching structure as it moves relative to the pen tube assembly 20, providing audio feedback to the user and improving the user experience.

[0032] See Figures 3-7In some embodiments, the pen tube assembly 20 includes a main support 23, which supports and fixes the internal components of the capacitive pen to ensure its normal operation. The main support 23 is fixed in the first receiving cavity 211, and the support back cover 22 is fixed to one end of the main support 23 near the pen cap assembly 30. In some embodiments, the main support 23 is provided with a first limiting member 231, and the pen cap 31 is provided with a second limiting member 311. When the pen cap support 32 slides axially, the third latching position 321 engages with the second latching position 222, and the first limiting member 231 abuts against the second limiting member 311, thereby preventing the pen cap 31 from detaching from the main support 23. For example, the first limiting member 231 includes a limiting post disposed on the main support 23, and the second limiting member 311 includes a sliding groove formed on the pen cap 31. The limiting post can move within the sliding groove. When the pen cap support 32 slides axially so that the third snap-fit ​​position 321 engages with the second snap-fit ​​position 222, the limiting post abuts against the end of the sliding groove. By designing the positioning post to limit the pen cap 31, the pen cap 31 can be effectively prevented from detaching from the main support 23. The limiting post can be set as a cylindrical structure, and the size of the limiting post is adapted to the size of the sliding groove.

[0033] See Figure 6 and Figure 7 In some embodiments, the pen cap holder 32 includes a spring wall 322, which can achieve elastic deformation and elastic reset. The spring wall 322 can be made of plastic. Specifically, the third fastening member is located on the side of the spring wall 322 near the back cover 22 of the holder, and there is a gap between the side of the spring wall 322 away from the back cover 22 and the pen cap 31, so as to provide a certain space for the elastic deformation and reset of the spring wall 322, which is conducive to better realizing the function of the spring wall 322. The above structure utilizes the elastic deformation and elastic reset of plastic to disengage and engage the fastener. The elastic deformation and elastic reset process of the spring wall 322 can provide the user with a fastening feel. Combined with the process of the third fastening member engaging with the first or second fastening member, the capacitive pen 10 with fastening structure provided by this application can provide a fastening sound and a fastening feel, providing the user with sound feedback and tactile feedback, which can improve the user's user experience.

[0034] See Figure 4 and Figure 5In some embodiments, the back cover 22 of the bracket has two grooves spaced apart along the axial direction to form a first latching position 221 and a second latching position 222, respectively. The pen cap bracket 32 ​​has a protrusion to form a third latching position 321, which can be engaged with either the first latching position 221 or the second latching position 222. In other embodiments, the back cover 22 of the bracket has two protrusions spaced apart along the axial direction to form a first latching position 221 and a second latching position 222, respectively. The pen cap bracket 32 ​​has a groove to form a third latching position 321, which can be engaged with either the first latching position 221 or the second latching position 222. Through the cooperation between the first latching position 221, the second latching position 222, and the third latching position 321, when the pen cap assembly 30 moves relative to the pen tube assembly 20, the capacitive pen 10 with the latching structure makes a sound due to the latching structure, providing sound feedback to the user and improving the user experience.

[0035] See Figure 3 In some embodiments, the capacitive pen 10 with the snap-fit ​​structure further includes a light guide component 40, which includes a light-emitting element 41 and a light guide component 42. The light guide component 42 can guide the light emitted by the light-emitting element 41 to prevent light leakage. Specifically, a second receiving cavity 312 is formed in the pen cap 31, and a through hole 3121 is formed at the end away from the pen tube assembly 20. The pen cap bracket 32 ​​is disposed in the second receiving cavity 312. The light-emitting element 41 is fixed to the end of the pen cap bracket 32 ​​near the through hole 3121. The light-emitting element 41 can be a light-emitting diode. The light guide 42 is clamped and fixed between the pen cap bracket 32 ​​and the pen cap 31. The light guide 42 is axially aligned with the light-emitting element 41. In some embodiments, the light guide 42 can be made of silicone. The light guide 42 extends into the through hole 3121 and is exposed on the outer surface of the pen cap 31. By setting the light guide assembly 40, the capacitive pen 10 with the snap-fit ​​structure has the function of emitting light. The light guide 42 can effectively guide the light emitted by the light-emitting element 41, avoid the light leakage phenomenon emitted by the light-emitting element 41, and has the function of saving energy and power.

[0036] See Figure 3In some embodiments, the first receiving cavity 211 houses a battery 2111 and a motherboard 2112. The conductive wires of the battery 2111 can be fixed to the motherboard 2112 by soldering. When installing the capacitive pen 10 with a snap-fit ​​structure, the semi-finished motherboard 2112 can be inserted into the main bracket 23. The rear cover 22 of the bracket is provided with a connector 223, which can be connected to the outside of the capacitive pen to charge it. The battery 2111 is electrically connected to the connector 223 through the motherboard 2112. The connector 223 is located between the first snap-fit ​​position 221 and the second snap-fit ​​position 222. When the pen cap bracket 32 ​​slides axially so that the third snap-fit ​​position 321 is engaged with the second snap-fit ​​position 222, a gap space is formed between the pen cap 31 and the pen tube 21, and the connector 223 is exposed in the gap space so that the user can charge the capacitive pen through the connector 223. In some embodiments, the pen cap 31 is provided with a clip 313, which can cover the connector 223 to improve the aesthetics of the capacitive pen. Specifically, an axial clearance groove 212 is formed at the rear end of the pen cap 31, and the connector 223 is located below the clearance groove 212, which ensures that the connector 223 is exposed in the space. When the pen cap bracket 32 ​​slides axially to engage the third latch 321 with the first latch 221, the clip 313 moves above the clearance groove 212 to cover the connector 223. When the connector 223 is not needed, the aesthetics of the capacitive pen are improved. At the same time, the clip 313 covering the connector 223 can also reduce the amount of dust falling into the holes of the connector 223 to a certain extent. When the pen cap holder 32 slides axially to engage the third latch position 321 with the second latch position 222, the clip 313 moves away from the clearance groove 212 to expose the connector 223 so that the user can charge the capacitive pen through the connector 223.

[0037] See Figure 3In some embodiments, the first receiving cavity 211 is equipped with a wireless charging component 2113, a pen tip component 2114, and a vibration component 2115. The wireless charging component 2113 mainly includes a transmitter and a receiver. Its principle is based on electromagnetic induction and power transmission. The coil of the transmitter generates alternating current through a power source, forming an alternating magnetic field. The coil of the receiver senses this magnetic field, generates an induced electromotive force, and stores electrical energy after processing by internal circuitry. The pen tip component 2114 includes a transmitter 2114a located at the front end of the pen tube 21. The battery 2111 is electrically connected to the wireless charging component 2113, the transmitter 2114a, and the vibration component 2115 through the main board 2112. The vibration component 2115 of the capacitive pen mainly includes a piezoelectric element and a piezoelectric flexible beam. It provides tactile feedback by generating vibration, enhancing the user experience. Specifically, the piezoelectric element can be installed inside the capacitive pen and will vibrate when current passes through it. The piezoelectric flexible beam is installed inside the outer shell of the capacitive pen and connected to the outer shell through a rigid bracket. When current flows through it, the piezoelectric flexible beam moves, creating a vibration effect. A tiny capacitor is formed between the levitation point of the transmitter 2114a and the sensor layer on the touch screen. When the levitation point contacts the touch screen, the capacitance value changes. The capacitive pen contains a detection circuit that measures and analyzes this capacitance change, converting the electrical signal into a digital signal, which is then transmitted to the device via a data cable or wireless signal to achieve precise control of the screen. In some embodiments, the capacitive pen 10 with a snap-fit ​​structure also includes a magnetic element 50, which is disposed within the first receiving cavity 211. The magnetic element 50 can be used to attach to the metal frame of a device such as a tablet for easy fixation and charging, allowing for convenient access and management of the capacitive pen.

[0038] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
