Description

Technical Field

[0001] This utility model relates to the field of intelligent whiteboard pen technology, and in particular to a dual-head interactive whiteboard pen. Background Technology

[0002] A smart whiteboard pen is a digital writing tool that integrates sensors, wireless communication, and data processing technologies. It is mainly compatible with electronic whiteboards, touch screens, and other devices, and is widely used in teaching, meetings, and other scenarios. Its core consists of a pen tip assembly, a built-in battery, a microprocessor, and a wireless module. The pen tip is often made of wear-resistant silicone or liquid material and supports pressure-sensitive recognition to reproduce the changes in writing thickness. Some models are equipped with function buttons to switch between writing and erasing modes. When working, it transmits signals via wireless technologies such as Bluetooth and 2.4G. With the help of accompanying software, it digitizes handwriting and can perform operations such as annotation, zooming, and saving. Some high-end models have functions such as digital aperture, timer reminders, and cloud sharing. It can also convert handwritten content into editable text. Most of them use a Type-C interface for charging and have a battery life of several hours. Some models support receiver anti-loss reminders, balancing writing experience with smart convenience.

[0003] However, the contacts of the smart whiteboard pen are directly exposed. During use, the contacts without a protective structure are easily deformed and dented when the pen is dropped, or worn due to friction when plugging and unplugging the charging cable or installing the pen tip. This can lead to poor charging contact, inability to transmit pressure-sensitive signals properly, shorten the lifespan of the pen, and affect the efficiency and user experience. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the contacts of smart whiteboard pens are directly exposed, and the contacts without protective structures are easily deformed or dented when the pen is dropped, or worn due to friction caused by daily plugging and unplugging of charging cables and installation of pen tips, resulting in poor charging contact, inability to transmit pressure-sensitive signals normally, shortening the lifespan of the pen, and affecting the efficiency and user experience. Therefore, this invention proposes a dual-head interactive whiteboard pen.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a dual-headed interactive whiteboard pen, comprising a pen barrel, a hanging rod, contacts, and a protective device. The hanging rod is fixedly connected to the pen barrel. Two contacts are fixed to one end of the pen barrel, respectively located at both ends. The protective device is disposed on the surface of the pen barrel and includes an assembly. The assembly is fixedly connected to the pen barrel. A torsion bar is rotatably connected to the surface of the assembly. A pressure bar is fixedly connected to the surface of the torsion bar. A cylinder is fixedly connected to one end of the pressure bar. A torsion spring is fitted onto the surface of the torsion bar. The two ends of the torsion spring are fixedly connected to the mounting bracket and the torsion bar, respectively. By setting a protective device, when the double-ended whiteboard marker is not in use, the elastic force of the torsion spring can drive the pressure rod and the cylinder to cover the contact point, reducing the direct exposure of the contact point to dust, chalk dust, or moisture and oxidation caused by tea spills. At the same time, it prevents the contact point from being deformed or worn when the marker is dropped, effectively reducing the problem of poor contact, ensuring stable transmission of the on / off key signal and normal operation of the electromagnetic wave transmitter, extending the service life of the contact point, and eliminating the need for frequent disassembly and maintenance.

[0006] Preferably, one end of the pressure rod is fixedly connected to an iron ring, and one end of the pen barrel is fixedly connected to a magnet. By setting the iron ring, when the double-ended whiteboard pen is needed, rotating the pressure rod moves the cylinder away from the contact point. At this time, the iron ring rotates with the pressure rod to a position opposite to the magnet. The iron ring and the magnet are tightly attracted by magnetic attraction, which stabilizes the pressure rod in the current position, ensuring that the cylinder continues to detach from the contact point, without affecting the normal pressure transmission of the switch, and ensuring that the pen body can smoothly realize the interaction function between the double pen tips and the smart whiteboard.

[0007] Preferably, the iron ring is magnetically connected to the magnet, and the cylinder is semi-circular. By setting the cylinder, when the double-ended whiteboard marker is not in use, it is moved to the contact point position by the pressure rod and the contact point is completely blocked, physically isolating external contaminants such as dust, chalk dust, and tea water, and preventing the contact point from being contaminated with impurities, which may lead to moisture oxidation or poor contact.

[0008] Preferably, the cylinder is sleeved with the contact point, and the pressure rod is inclined.

[0009] Preferably, the inner wall of the pen barrel is provided with a shock-absorbing component, which includes a rubber ring located in the inner wall of the pen barrel. A pressure spring is fixedly connected to the surface of the rubber ring. By providing the shock-absorbing component, when the pen barrel is accidentally dropped, the pressure spring can buffer the impact force generated by the impact with the ground. The rubber ring can further protect the internal control circuit, electromagnetic wave emitting device, power supply battery and other components of the pen barrel, reduce the risk of internal parts breaking, loosening or circuit damage due to severe impact, reduce the probability of pen failure, ensure that the dual-head whiteboard pen can still normally realize the interaction function between the dual pen heads and the smart whiteboard, and reduce the cost of replacing parts and the impact of interruption of use.

[0010] Preferably, the end of the pressure spring furthest from the rubber ring is fixedly connected to the pen barrel. The pressure spring is located between the rubber ring and the pen barrel. By setting the pressure spring, when the pen barrel accidentally falls and contacts the ground, the impact force will be transmitted to the pressure spring, causing the spring to compress and deform. During this process, the spring converts the kinetic energy of the impact into elastic potential energy, which greatly weakens the impact force transmitted to the inside of the pen barrel.

[0011] Preferably, there are multiple pressure springs, and the multiple pressure springs are arranged in a circumferential array along the rubber ring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a protective device, the double-headed whiteboard pen consists of two pen heads and a pen barrel connecting them. The control circuit inside the pen barrel is the core, electrically connected to the on / off switch, electromagnetic wave emitting device, and power supply battery in each of the two pen heads. The power supply battery provides power to the entire device. When the on / off switch of any pen head is pressed or both pen heads are pressed simultaneously, the on / off switch transmits an electrical signal to the control circuit. After receiving the signal, the control circuit drives the electromagnetic wave emitting device to work, causing it to emit a specific electromagnetic wave. The smart whiteboard receives this electromagnetic wave and identifies the pen head operation corresponding to the emitted signal, thereby realizing the function that both pen heads can interact with the smart whiteboard. The pressure rod drives the cylinder away from the whiteboard. The contact point is then rotated. Once the iron ring and magnet are magnetically attracted and fixed, it can be used. When the pressure rod is rotated, the iron ring and magnet disengage, and the torsion spring, freed from its restraint, generates elastic force to compress the pressure rod, which in turn drives the cylinder to shield the contact point. By setting up a protective device, when the double-ended whiteboard marker is not in use, the elastic force of the torsion spring drives the pressure rod and cylinder to shield the contact point, reducing the direct exposure of the contact point to dust, chalk dust, or moisture and oxidation caused by spilled tea. At the same time, it prevents the contact point from being deformed or worn when the marker is dropped, effectively reducing contact problems, ensuring stable transmission of the on / off key signal and normal operation of the electromagnetic wave transmitter, extending the service life of the contact point, and eliminating the need for frequent disassembly and maintenance.

[0014] 2. In this utility model, by setting a shock-absorbing component, when the pen barrel falls, the ground impacts the pen barrel, generating elastic force. The pressure spring buffers the pressure, while the rubber ring protects the components inside the pen barrel, preventing the internal parts from breaking. By setting a shock-absorbing component, when the pen barrel is accidentally dropped, the pressure spring can buffer the impact force generated by the ground impact, and the rubber ring can further protect the control circuit, electromagnetic wave emitting device, power supply battery and other components inside the pen barrel, reducing the probability of internal parts breaking, loosening or circuit damage due to severe impact, reducing the probability of pen body failure, ensuring that the dual-head whiteboard pen can still normally realize the interaction function between the dual pen heads and the smart whiteboard, reducing the cost of replacing parts and the impact of use interruption.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a double-headed interactive whiteboard pen, including a pen barrel 1, a hanging rod 2, a contact point 3 and a protective device 4. The hanging rod 2 is fixedly connected to the pen barrel 1. The contact point 3 is fixed at one end of the pen barrel 1. There are two contact points 3, which are respectively set at both ends of the pen barrel 1. The protective device 4 is set on the surface of the pen barrel 1.

[0022] In this implementation scheme: the protective device 4 includes a mounting bracket 44, which is fixedly connected to the pen barrel 1. A torsion bar 46 is rotatably connected to the surface of the mounting bracket 44. A pressure bar 41 is fixedly connected to the surface of the torsion bar 46. A cylinder 42 is fixedly connected to one end of the pressure bar 41. A torsion spring 47 is sleeved on the surface of the torsion bar 46. The two ends of the torsion spring 47 are fixedly connected to the mounting bracket 44 and the torsion bar 46, respectively. By setting the protective device 4, when the double-ended whiteboard marker is not in use, the elastic force of the torsion spring 47 can drive the pressure bar 41 and the cylinder 42 to cover the contact point 3, reducing the direct exposure of the contact point 3 to dust, chalk dust, or moisture and oxidation caused by tea spills. At the same time, it prevents the contact point 3 from being deformed and worn when the pen body is dropped, effectively reducing the problem of poor contact of the contact point 3, ensuring the stable transmission of the on / off key signal and the normal operation of the electromagnetic wave transmitter, extending the service life of the contact point 3, and eliminating the need for frequent disassembly and maintenance.

[0023] Specifically, one end of the pressure rod 41 is fixedly connected to an iron ring 43, and one end of the pen barrel 1 is fixedly connected to a magnet 48. By setting the iron ring 43, when the double-headed whiteboard pen is needed, the pressure rod 41 is rotated to move the cylinder 42 away from the contact point 3. At this time, the iron ring 43 rotates with the pressure rod 41 to a position opposite to the magnet 48. The iron ring 43 and the magnet 48 are tightly attracted by magnetic attraction, which stabilizes the pressure rod 41 in the current position, ensuring that the cylinder 42 continues to detach from the contact point 3, without affecting the normal pressure transmission of the switch, and ensuring that the pen body can smoothly realize the interaction function between the double pen heads and the smart whiteboard.

[0024] Specifically, the iron ring 43 is magnetically connected to the magnet 48, and the cylinder 42 is semi-circular. By setting the cylinder 42, when the double-ended whiteboard marker is not in use, it is moved to the position of the contact point 3 by the pressure rod 41 and the contact point 3 is completely blocked, physically isolating external contaminants such as dust, chalk dust, and tea water, and preventing the contact point 3 from being contaminated with impurities, which may lead to moisture oxidation or poor contact.

[0025] Specifically, the cylinder 42 is sleeved with the contact point 3, and the pressure rod 41 is set at an angle.

[0026] Specifically, the inner wall of the pen barrel 1 is provided with a shock-absorbing component 45, which includes a rubber ring 452. The rubber ring 452 is located in the inner wall of the pen barrel 1, and a pressure spring 451 is fixedly connected to the surface of the rubber ring 452.

[0027] In this embodiment: by setting the shock absorption component 45, when the pen barrel 1 is accidentally dropped, the pressure spring 451 can buffer the impact force generated by the impact of the ground, and the rubber ring 452 can further protect the control circuit, electromagnetic wave emitting device, power supply battery and other components inside the pen barrel 1, reduce the breakage, loosening or circuit damage of internal parts due to violent impact, reduce the probability of pen failure, ensure that the double-headed whiteboard pen can still normally realize the interaction function between the double pen heads and the smart whiteboard, and reduce the cost of replacing parts and the impact of interruption of use.

[0028] Specifically, the end of the pressure spring 451 away from the rubber ring 452 is fixedly connected to the pen barrel 1, and the pressure spring 451 is located between the rubber ring 452 and the pen barrel 1.

[0029] In this embodiment: by setting a pressure spring 451, when the pen barrel 1 accidentally falls and contacts the ground, the impact force will be transmitted to the pressure spring 451, causing the spring to compress and deform. During this process, the spring converts the kinetic energy of the impact into elastic potential energy, which greatly weakens the impact force transmitted to the inside of the pen barrel 1.

[0030] Specifically, there are multiple pressure springs 451, which are arranged in a circumferential array along the rubber ring 452.

[0031] Working Principle: With the protective device 4, this dual-headed whiteboard marker consists of two pen tips and a pen barrel 1 connecting them. The control circuit inside the pen barrel 1 serves as the core, electrically connected to the on / off switches, electromagnetic wave transmitters, and power supply batteries in both pen tips. The power supply battery provides power to the entire device. When the on / off switch of any pen tip is pressed, or when the on / off switches of both pen tips are pressed simultaneously, the on / off switch transmits an electrical signal to the control circuit. After receiving the signal, the control circuit drives the electromagnetic wave transmitter to emit a specific electromagnetic wave. The smart whiteboard receives this electromagnetic wave and identifies the pen tip operation corresponding to the emitted signal, thus enabling both pen tips to interact with the smart whiteboard. The pressure rod 41 moves the cylinder 42 away from the contact point 3. Then, the pressure rod 41 is rotated, and when the iron ring... After the iron ring 43 is magnetically fixed to the magnet 48, it can be used. When the pressure rod 41 is rotated, the iron ring 43 is separated from the magnet 48. The torsion spring 47 loses its restraint and generates elastic force to squeeze the pressure rod 41, which in turn drives the cylinder 42 to cover and protect the contact point 3. By setting the protective device 4, when the double-ended whiteboard pen is not in use, the elastic force of the torsion spring 47 can drive the pressure rod 41 and the cylinder 42 to cover the contact point 3, reducing the direct exposure of the contact point 3 to dust, chalk dust, or tea spills that cause moisture and oxidation. At the same time, it prevents the contact point 3 from being deformed and worn when the pen is dropped, effectively reducing the problem of poor contact of the contact point 3, ensuring the stable transmission of the on / off key signal and the normal operation of the electromagnetic wave transmitter, extending the service life of the contact point 3, and eliminating the need for frequent disassembly and maintenance.

[0032] By incorporating the shock-absorbing component 45, when the pen 1 falls, the impact of the ground on the pen 1 generates elastic force. The pressure spring 451 buffers the pressure, while the rubber ring 452 protects the components inside the pen 1, preventing the internal parts of the pen 1 from breaking. By incorporating the shock-absorbing component 45, when the pen 1 is accidentally dropped, the pressure spring 451 can buffer the impact force generated by the ground impact, and the rubber ring 452 can further protect the internal control circuit, electromagnetic wave emitting device, power supply battery and other components of the pen 1, reducing the risk of internal parts breaking, loosening or circuit damage due to severe impact, reducing the probability of pen failure, ensuring that the dual-head whiteboard pen can still normally realize the interaction function between the dual pen heads and the smart whiteboard, reducing the cost of replacing parts and the impact of use interruption.
