Description

Technical Field

[0001] The present invention relates to the technical field of capacitive pens, and in particular to an active capacitive pen with a portable Wi-Fi function and a signal receiving method thereof. Background Art

[0002] An active capacitive stylus is a high-precision input device that interacts with a touch screen through built-in circuits. Compared to a passive capacitive stylus (which only simulates finger touch), it has advantages such as pressure sensitivity, tilt detection, and low latency. It is widely used in drawing, note-taking, design, and other fields.

[0003] However, existing active capacitive pens have a single data transmission method and must be connected to terminal devices such as mobile phones or tablets via Bluetooth to achieve handwriting synchronization. In addition, they cannot work independently when there is no terminal or the network environment is poor. The lack of storage capacity means that the pen body does not have an integrated storage module, and data loss will occur when the network is disconnected. The metal pen body has a shielding effect of more than -15dB on the 2.4GHz signal. Summary of the Invention

[0010] The signal adjustment mechanism includes a sliding ring, an embedded tube, a mounting block, a rotating rod and a signal amplifier. A mounting hole is provided at the leftmost end of the capacitive pen body, a fixing ring is fixedly connected to the inner wall of the mounting hole, a connecting tube is fixedly connected to the side of the capacitive pen body close to the mounting hole, a wire hole is provided at one end of the connecting tube, the sliding ring is slidably connected to the inside of the connecting tube, an embedded tube is fixedly connected to one side of the sliding ring, two mounting blocks are fixedly connected to one side of the embedded tube, the two mounting blocks are symmetrically arranged, two signal amplifiers are arranged between the two mounting blocks, one end of the two signal amplifiers is respectively fixedly connected to two rotating rods, and the other end passes through the fixing ring, and the two groups of rotating rods are rotatably connected between the two mounting blocks.

[0011] It also includes a guide block, a limiting ring and a tough piece.

[0014] A method for receiving signals from an active capacitive stylus pen with a portable Wi-Fi function comprises the following steps:

[0015] S1. WiFi function: Due to the WiFi module, the capacitive pen can be directly connected to the router without relying on a mobile phone or tablet, making it convenient to import notes or handwriting records into an external terminal for processing. It also supports SoftAP mode, converting 4G or wired network into a WiFi hotspot, so that when you are outdoors, you can share the mobile network with a laptop through the capacitive pen hotspot.

[0016] S2. Signal range: By moving the sliding ring to a magnetic connection with one side of the fixed ring, the two signal amplifiers are extended from one end of the capacitive pen body, and the position of the signal amplifier is easily rotated through the cooperation of the toughness sheet and the guide block to achieve the expansion of the WiFi signal or signal reception range.

[0017] S3. Command reception: When the user places the pressure-sensitive pen tip close to the location to be read on the external device, the pressure-sensitive pen tip imports the recognized command into the command chip for processing, and then imports the command into the speaker for processing, and then releases it through the sound hole, thereby completing the command playback;

[0018] S4. Anti-accidental touch: Due to the infrared proximity sensor, the anti-accidental touch function can be realized according to the distance between the pressure-sensitive pen tip and the external screen. In conjunction with the six-axis gyroscope, the user's holding posture can be detected in real time.

[0019] The beneficial effects of the present invention are as follows:

[0020] The present invention provides a Wi-Fi module so that the capacitive pen body can be directly connected to a router without relying on a mobile phone or tablet, making it convenient to import notes or handwriting records into an external terminal for processing. At the same time, it supports SoftAP mode, converting 4G or wired network into a Wi-Fi hotspot. This makes it convenient to share the mobile phone network with a laptop computer through the capacitive pen body hotspot when outdoors. In this way, the capacitive pen body has independent networking capabilities, realizing offline note synchronization, cross-device collaboration and real-time cloud backup functions, and solving the data island problem in a networkless environment.

[0021] The present invention pulls the cover plate to rotate on one side of the fixed ring, thereby driving the elastic net to rotate. Cooperating with the two positioning holes, the two signal amplifiers are conveniently separated from the elastic net, thereby releasing the restriction on the signal amplifiers. By pulling the sliding ring until one side of the sliding ring is magnetically connected to one side of the fixed ring, the two signal amplifiers are completely located outside the capacitive pen body. When the signal amplifier is pulled and the rotating rod is cooperated, when the guide block contacts the tough piece, the guide block drives the tough piece to bend slightly, while facilitating the rotation of the guide block, thereby gradually adjusting the angle of the signal amplifier to achieve the expansion of the WiFi signal or signal reception range.

[0037] Example 1, below in conjunction with the attached Figure 1 -Attached Figure 6 The present invention is further described.

[0038] An active capacitive stylus with a portable Wi-Fi function comprises a capacitive stylus body 1, a Wi-Fi main control chip 3, a support and adjustment mechanism 6, and a blocking mechanism 7.

The blocking mechanism 7 is arranged at the leftmost end of the capacitive stylus body 1, and one side of the signal adjustment mechanism 6 is hingedly connected to the blocking mechanism 7 and is used to limit the position of the signal adjustment mechanism.

[0039] Specifically, through the wifi main control chip 3, the capacitive pen body 1 can be directly connected to the router without relying on a mobile phone or tablet, making it convenient to import notes or handwriting records into an external terminal for processing. At the same time, it supports SoftAP mode, converting 4G or wired network into a wifi hotspot, so that when in the wild, the mobile network can be shared with a laptop through the hotspot of the capacitive pen body 1.

When the power is lower than 20%, the hotspot function is automatically turned off to prioritize handwriting storage.

[0042] A power module 4 is installed inside the capacitive pen body 1 near the left side of the wifi main control chip 3. The power module 4 includes a power button 401, a charging port 402, an indicator light 403 and a battery 404. The power button 401 is installed on the outside of the capacitive pen body 1.

An indicator light 403 is installed on the outside of the capacitive pen body 1 near the charging port 402. A battery 404 is installed inside the capacitive pen body 1 near the left side of the wifi main control chip. Specifically, charging instructions can be given to the battery 404 through the charging port 402, and the charging status of the battery 404 can be observed through the indicator light 403.

[0043] A sound amplification module 5 is provided at the left end of the capacitive pen body 1. The sound amplification module 5 includes a sound hole 501 and a speaker 502. There are several sound holes 501, and the several sound holes 501 are opened on the outer wall of the capacitive pen body 1. Speakers 502 are installed on one side of the capacitive pen body 1 corresponding to the several sound holes 501. Specifically, the recognized instructions are introduced into the instruction chip 301 for processing through the pressure-sensitive pen tip 201, and then the instructions are introduced into the speaker 502 for processing, and then released through the sound hole 501 to complete the instruction playback.

[0044] The signal adjustment mechanism 6 includes a sliding ring 605, an embedded cylinder 606, a mounting block 607, a rotating rod 608 and a signal amplifier 609. The leftmost end of the capacitive pen body 1 is provided with a mounting hole 601, the inner wall of the mounting hole 601 is fixedly connected to a fixing ring 602, the inner side of the capacitive pen body 1 near the mounting hole 601 is fixedly connected to a connecting cylinder 603, one end of the connecting cylinder 603 is provided with a wire hole 604, the sliding ring 605 is slidably connected to the inside of the connecting cylinder 603, one side of the sliding ring 605 is fixedly connected to the embedded cylinder 606, and one side of the embedded cylinder 606 is fixedly connected to two mounting blocks 607. The two mounting blocks 608 are fixedly connected to the inner side of the connecting cylinder 603. 07 is symmetrically arranged, and two signal amplifiers 609 are arranged between the two mounting blocks 607. One end of the two signal amplifiers 609 is fixedly connected to two rotating rods 608, and the other end passes through the fixed ring 602. The two sets of rotating rods 608 are respectively rotatably connected between the two mounting blocks 607. Specifically, when the signal amplifier 609 is pulled toward the outside of the capacitive pen body, the signal amplifier 609 will drive the sliding ring 605 to slide inside the connecting tube 603, so that the sliding ring 605 will drive one end of the two signal amplifiers 609 to slide out of the outside of the capacitive pen body 1, so as to facilitate subsequent signal amplification processing.

[0045] The guide block 610 is fixedly connected to one side of the mounting block 607, and the two limit rings 611 are respectively sleeved on the outer wall of a rotating rod 608 in each group. A plurality of tough sheets 612 are fixedly connected to one side of the limit ring 611. A guide block 610 is fixedly connected between the outer wall of the rotating rod 608 near two adjacent tough sheets 612. Specifically, when the signal amplifier 609 drives the rotating rod 608 to rotate, the rotating rod 608 drives the plurality of guide blocks 610 to rotate between the plurality of tough sheets 612. At the same time, when the guide block 610 contacts the tough sheet 612, the guide block 610 drives the tough sheet 612 to bend slightly, which facilitates the rotation of the guide block 610. When a guide block 610 is separated from a tough sheet 612, the tough sheet 612 is reset, thereby limiting the position of the guide block 610, thereby adjusting the angle of the signal amplifier 609.

[0046] One side of the fixed ring 602 is magnetically connected to one side of the sliding ring 605. Specifically, when one side of the fixed ring 602 moves to be magnetically connected to one side of the sliding ring 605, the fixed ring 602 drives one side of the embedded tube 606 to be flush with one side of the fixed ring 602, so that the two signal amplifiers 609 are completely located outside the capacitive pen body 1.

[0047] The blocking mechanism 7 includes a cover plate 701, an elastic net 702 and a positioning hole 703. One side of the cover plate 701 is hinged to one side of the signal adjustment mechanism 6. An elastic net 702 is embedded in one side of the cover plate 701. Two positioning holes 703 are opened on one side of the elastic net 702. Specifically, when the capacitive pen body 1 is used normally, the elastic net 702 on the cover plate 701 drives the two positioning holes 703 to pass through the head ends of the two signal amplifiers 609 respectively, thereby restricting the two signal amplifiers 609 inside the connecting tube 603.

[0048] Example 2, below in conjunction with the attached Figure 7 The present invention is further described as follows: A method for receiving signals from an active capacitive stylus with a portable Wi-Fi function comprises the following steps:

[0049] S1. Wi-Fi function: Due to the Wi-Fi module 303, the capacitive pen body 1 can be directly connected to a router without relying on a mobile phone or tablet, making it convenient to import notes or handwriting records into an external terminal for processing. It also supports SoftAP mode, converting 4G or wired networks into Wi-Fi hotspots, so that when you are outdoors, you can share the mobile network with a laptop through the hotspot of the capacitive pen body 1.

[0050] S2. Signal range: By moving the sliding ring 605 to be magnetically connected to one side of the fixed ring 602, the two signal amplifiers 609 are extended out of one end of the capacitive pen body 1, and the position of the signal amplifier 609 is conveniently rotated through the cooperation of the tough piece 612 and the guide block 610 to achieve the expansion of the WiFi signal or signal reception range.

[0051] S3. Command reception: When the user places the pressure-sensitive pen tip 201 close to the location to be read on the external device, the pressure-sensitive pen tip 201 imports the recognized command into the command chip 301 for processing, and then imports the command into the speaker 502 for processing, and then plays it out through the sound hole 501, thereby completing the command playback;

[0052] S4. Anti-accidental touch: Due to the function of the infrared proximity sensor 202, the anti-accidental touch function can be realized according to the distance between the pressure-sensitive pen tip 201 and the external screen, and in conjunction with the six-axis gyroscope 203, the user's holding posture can be detected in real time.

[0053] In summary: When the present invention is in use, due to the WiFi module 303 provided, the capacitive pen body 1 can be directly connected to a router without relying on a mobile phone or tablet, making it convenient to import notes or handwriting records into an external terminal for processing. At the same time, it supports SoftAP mode, converting 4G or wired network into a WiFi hotspot, so that when in the wild, the mobile phone network can be shared with a laptop computer through the hotspot of the capacitive pen body 1, so that the capacitive pen body has independent networking capabilities, realizing offline note synchronization, cross-device collaboration and real-time cloud backup functions, solving the data island problem in a networkless environment. If there is an available network, the handwriting is uploaded to the cloud server in real time through the WiFi module 303. If there is no network, the handwriting is encrypted and stored in the memory 302. When the network is restored, the offline handwriting data is automatically synchronized to the cloud, and the Bluetooth receiver 304 is used to facilitate quick pairing of external devices.

[0054] During use, when using the capacitive stylus body 1, long press the power button 401 to start or shut down. When the power button 401 controls the battery 404 to start, the capacitive stylus body 1 is turned on. In conjunction with the charging port 402, a charging instruction can be issued to the battery 404, and the charging status of the battery 404 can be observed through the indicator light 403. When the user brings the pressure-sensitive stylus tip 201 close to the place on the external device that needs to be read, the pressure-sensitive stylus tip 201 imports the recognized instruction into the instruction chip 301 for processing, and then imports the instruction into the speaker 502 for processing, and then releases it through the sound hole 501 to complete the instruction playback. Due to the function of the infrared proximity sensor 202, the anti-mistouch function can be realized according to the distance between the pressure-sensitive stylus tip 201 and the external screen, and in conjunction with the six-axis gyroscope 203, the user's holding posture can be detected in real time;

[0055] When the capacitive stylus body 1 is used normally, the elastic net 702 on the cover 701 drives the two positioning holes 703 to pass through the two signal amplifiers 609 head ends respectively, thereby restricting the two signal amplifiers 609 inside the connecting tube 603. In the field, the signal reception is unstable. At this time, the cover 701 is pulled to rotate on one side of the fixed ring 602, so that the cover 701 drives the elastic net 702 to rotate, and then the elastic net 702 drives the two positioning holes 703 to separate from the two signal amplifiers 609 head ends respectively, thereby releasing the restriction on the signal amplifier 609, pulling the signal amplifier 609, so that the signal amplifier 609 drives the sliding ring 605 to slide inside the connecting tube 603 until one side of the sliding ring 605 is aligned with the fixed ring 602. Side magnetic connection, at this time the two signal amplifiers 609 are completely located outside the capacitive pen body 1, pulling the signal amplifier 609, so that the signal amplifier 609 drives the rotating rod 608 to rotate, and the rotating rod 608 drives several guide blocks 610 to rotate between several tough pieces 612 respectively. At the same time, when the guide block 610 contacts the tough piece 612, the guide block 610 drives the tough piece 612 to bend slightly, which facilitates the rotation of the guide block 610. When a guide block 610 is separated from a tough piece 612, the tough piece 612 is reset, thereby limiting the position of the guide block 610. By continuously rotating the signal amplifier 609, the angle of the signal amplifier 609 is gradually adjusted to achieve the expansion of the WiFi signal or signal reception range.
