Description

Technical Field

[0001] This invention relates to the field of writing instruments and photoelectric measurement equipment, specifically a multifunctional pen that integrates laser ranging and illumination. Background Technology

[0002] In construction, interior design, site surveying, and daily office work, workers typically need to obtain the distance dimensions of target objects and immediately record the measurement data. Currently, workers generally use a method of holding a rangefinder in their left hand and a pen and notebook in their right. However, existing conventional pens have limited functionality and cannot provide measurement assistance; while after measuring with a standalone laser rangefinder, workers often need to put it down or put it in their pocket to free their hands to write. This frequent switching between measuring and writing tools is cumbersome, not only reducing on-site work efficiency but also easily causing the equipment to slip and be damaged in complex construction sites lacking desktop support.

[0003] With the development of miniaturization technology for electronic components, electronic pens with additional functions have gradually appeared on the market. To enable scrolling of electronic menus and confirmation of commands, these multi-functional pens typically have holes on the side of the pen body and install multiple traditional micro-switches. However, due to the extremely limited surface area and internal space of the pen body, the layout of physical buttons is often very cramped, making it easy for users to accidentally press buttons when operating blindly while holding the pen. Furthermore, traditional buttons or dials lack comfortable and clear physical tactile feedback, resulting in a poor menu selection experience. In addition, there are unavoidable mechanical assembly gaps between traditional buttons and the pen body shell, allowing external moisture and dust to easily penetrate into the pen body, potentially causing short circuits or oxidation of the internal PCB circuitry, resulting in poor overall device protection.

[0004] Furthermore, in dimly lit working environments, such as underground parking garages, nighttime construction sites, and inspections of low-voltage electrical wells, traditional writing pens cannot clearly see the paper when recording data. Although some existing writing pens have lighting functions, their lighting circuits mostly rely on a separate mechanical toggle switch or push-button switch to turn on and off. Users need to be distracted to find and manually turn on the lighting switch before writing; a more significant pain point is that users often forget to turn off the separate lighting switch after writing and retracting the pen refill, resulting in the device's already limited battery capacity being wasted for an extended period. At the same time, the separate lighting switch and its wiring structure further encroach on the valuable assembly space inside the pen holder, which is not conducive to the highly integrated design of multi-functional pens. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-functional pen that integrates laser rangefinder and illumination. This solves the problems of existing conventional writing tools having limited functionality, requiring frequent switching between rangefinder and pen in rangefinding and recording scenarios, which is inconvenient to carry and operate. Existing multi-functional pens with electronic functions have cramped interactive switch layouts, cumbersome operation, and lack of tactile feedback. Furthermore, in low-light environments, traditional illuminated pens require manually finding and pressing a separate switch to turn the illumination on and off, resulting in numerous operation steps and potential power loss due to forgetting to turn off the light.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0019] This invention provides a multifunctional pen that integrates laser rangefinding and illumination. It has the following beneficial effects:

[0020] 1. This invention breaks through the internal space limitations of traditional multi-functional pens, innovatively adopting a split spatial layout. The laser emitting module is cleverly hidden in the protrusion of the pen clip, while the larger laser receiving part is placed in the middle of the pen body. This layout not only ensures a complete laser receiving and receiving path, but also maintains the slender feel of the writing pen. At the same time, the pen core, which is coaxially set inside, has a pen output direction that is completely opposite to the distance measurement and receiving directions, forming a non-interfering structure with one end for accurate distance measurement and the other end for writing and recording. This greatly improves the continuity of on-site operations and the portability of the equipment. In addition, the dedicated optical bracket inside further ensures the accurate refraction of the light path and prevents light path deviation caused by assembly tolerances.

[0021] 2. This invention incorporates a Hall effect knob control assembly on the outer wall of the pen body. The magnet on the inner wall of the knob, in conjunction with an internal Hall effect sensor, identifies rotation signals to activate menu operations. Alternating magnetic attraction and repulsion forces are generated by the knob's reset magnet and rotating magnet on the outer wall, providing users with a clear tactile feedback of rotation segments. Simultaneously, the design incorporates a ball-head pin in the internal groove of the knob pressing a waterproof ring to trigger the confirmation button. This achieves quick one-finger interaction for menu scrolling and confirmation while ensuring the internal circuit components are sealed and waterproof, effectively avoiding the shortcomings of traditional multi-button layouts, such as cramped layouts, susceptibility to accidental touches, and vulnerability to water damage.

[0022] 3. This invention designs a structure that links writing action with lighting activation and deactivation. The internal conductive connector, pen refill body, and conductive springs at both ends are connected in series to form a positive power supply circuit. When the user rotates the pen holder to extend the pen refill downwards in preparation for writing, the positive conductive spring of the pen refill light at the bottom is compressed and physically contacts the bottom conductive ring, instantly connecting the power supply circuit and illuminating the front light-emitting unit. When the pen refill is retracted, the spring naturally separates, and the circuit is broken. This structure eliminates the tedious steps of manually finding and pressing an independent switch, achieving instant lighting when the pen is extended and instant deactivation when the pen is retracted. This not only saves the limited structural space inside the pen holder but also fundamentally eliminates the problem of power loss caused by forgetting to turn off the light.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example:

[0034] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a multi-functional pen integrating laser ranging and illumination, comprising: the main body of the device is composed of a pen body tube 5, a pen body cover 6 is fixedly connected to the outer wall of the top of the pen body tube 5, a pen clip 7 with a protrusion and a display screen bracket 2 are fixedly connected to one side of the outer wall, a body adapter 15 and a bottom cover 14 are fixedly connected to the bottom of the inner end, a TYPE-C interface 903 is fixedly connected inside the bottom cover 14, a battery 10 for power supply is provided inside the pen body tube 5 near the upper part of the body adapter 15, and a pen PCB 9 is fixedly connected inside the pen body tube 5;

[0035] A laser rangefinder assembly is housed inside the pen body 5 and pen clip 7. This assembly includes a laser emitting module 710 fixed inside the pen clip 7. A laser emitting window 8 is located at the top of the pen clip 7 and above the laser emitting module 710. A rangefinder module bracket 706 is fixedly connected inside the pen body 5. The rangefinder module bracket 706 is used to integrate and fix the various optical components of the receiving part. A laser rangefinder module 708 and a laser rangefinder module 709 are fixedly connected to its outer side. A receiving lens bracket 705 and a reflector bracket 707 are fixedly connected to the rangefinder module bracket. The laser receiving lens 701 and the filter 704 are stably supported by the receiving lens bracket 705 on the inner wall of the frame 706, and the laser receiving mirror 702 is tilted and fixed by the reflecting mirror bracket 707. The above optical elements are all set in conjunction with the laser receiving window mirror 1 below the inner side of the top of the pen body tube 5, so as to accurately converge and refract the reflected light to the photoelectric sensor 703 located on the lower side during distance measurement, to prevent the optical path from being offset due to assembly tolerance. The distance measurement result is finally displayed through the display module 4 fixed inside the display frame 2 and through the external display window mirror 3.

[0036] The outer wall of the pen body 5 is fitted with a Hall effect knob control assembly. This assembly includes a knob button 11 rotatably connected to the outside of the pen body 5. Multiple magnets 1101 are fixed in a circular array on the inner wall of the knob button 11. Correspondingly, two Hall effect sensors 901 are fixed on the outer surface of the pen PCB 9. When the user rotates the knob button 11, it causes the magnets 1101 to rotate, generating a change in the magnetic field. This change is detected by the Hall effect sensors 901, which then generate a signal. Simultaneously, the knob reset magnet 12 fixed to the outer wall of the pen body 5 engages with the inner side of the magnets 1101 to produce a reset signal. The alternating magnetic field provides a tactile feedback when rotating. In addition, the inner wall of the knob button 11 has a groove, and a ball head pin 13 is slidably connected inside. Button 902 is fixed on the outer wall of the pen PCB 9. A waterproof ring 16 is fitted on the inner wall of the pen body 5. When the knob button 11 is pressed inward, one end of the ball head pin 13 extends into the waterproof ring 16 and presses inward, eventually abutting the trigger button 902. The waterproof ring 16 can both ensure the sealing and waterproofing of the external environment and realize the mechanical transmission of the confirmation operation command.

[0037] A lighting component is provided below the body adapter 15. The top of the outer shell pen refill lifting cylinder 17 is fixed to the outer wall of the body adapter 15. The cylinder pen grip 24 is rotatably connected to the outside of the outer shell pen refill lifting cylinder 17. The inner wall of the outer shell pen refill lifting cylinder 17 is rotatably connected to a negative conductive pen refill lifting sleeve 22 with a pen refill lifting threaded guide groove 2201. The outer wall of the insulating pen refill lifting sleeve 20 is fixed with an insulating pen refill lifting guide groove pin 2001. The pin is slidably connected inside the pen refill lifting threaded guide groove 2201. The rotation of the cylinder pen grip 24 drives the negative conductive pen refill lifting sleeve 22 to rotate, which forces the insulating pen refill lifting sleeve 20 to drive the internally slidably connected pen refill body 23 to move downward and extend against the pen refill lifting spring 29 sleeved on the outer wall. The bottom of the inner wall of the outer shell pen refill lifting cylinder 17 is fixed with an insulating pen refill pressure ring 26. A pen refill lifting limit 27 is provided on its inner side. A waterproof ring 25 is sleeved on the outer side near the inner wall of the cylinder pen grip 24.

[0038] Meanwhile, a spring pin 904 is fixed at the bottom of the pen PCB9, and the positive electrode conductive female connector 18 of the pen abuts against the spring pin 904. A positive electrode insulating sleeve 19 is sleeved on its outer wall. Together with the pen core conductive sheet 21 fixed on the outer wall of the pen core body 23 and the pen core top conductive spring 32 that is connected to the top and abuts against the lower surface of the pen core conductive female connector 18, a positive electrode conduction path for lighting power supply is formed. The bottom of the pen core lifting pen cylinder 17 is fixed with a light-emitting unit 905, and a pen core lamp PCB positive electrode conductive ring 906 is fixed above it. A pen core lamp light guide ring 31 is sleeved around it. When the pen core body 23 is in use, the pen core is raised. 3. When the pen refill body 23 slides down and extends into place, the positive electrode conductive spring 28 of the pen refill lamp, which is sleeved at its bottom end, is compressed. Its bottom end just abuts against the upper surface of the positive electrode conductive ring 906 of the pen refill lamp PCB, and the positive power supply circuit is turned on, lighting up the light-emitting unit 905. The light source is emitted through the pen refill lamp light guide ring 31. At the same time, the negative electrode conductive wave spring 30 of the pen refill lamp, which is set on the periphery of the bottom end, maintains the negative electrode path of the system. When the pen refill body 23 is retracted, the positive electrode conductive spring 28 of the pen refill lamp separates from the conductive ring, breaking the circuit, and the lighting automatically turns off, realizing the mechanical linkage between writing action and lighting on / off in the compact space inside the pen holder.

[0039] Working principle: When a multi-functional pen integrating laser rangefinder and illumination is needed, firstly, when the user switches functions, they rotate the external knob button 11. When the knob button 11 rotates, it drives multiple magnets 1101 on the inner wall to rotate synchronously. The Hall sensor 901 on the pen PCB9 detects the change in the magnetic field generated by the rotation of magnets 1101 and generates an encoded signal to scroll the menu. At the same time, the knob reset magnet 12 fixed on the outer wall of the pen body 5 generates an alternating magnetic attraction and repulsion with magnets 1101, providing a tactile feel for the rotation.

[0040] Secondly, after selecting a function, the user presses the knob button 11 inward, which causes the internal ball pin 13 to slide inward in the groove. The ball pin 13 squeezes the waterproof ring 16 and abuts against the button 902 on the contact pen PCB9 to complete the command input.

[0041] Then, after receiving the command, the pen PCB9 controls the laser emitting module 710 to work. The laser emitted by the laser emitting module 710, which is located in the protrusion of the pen clip 7, passes through the laser emitting window mirror 8 and illuminates the target surface. The reflected light enters from the laser receiving window mirror 1 on the inner side of the top of the pen body tube 5, passes through the laser receiving lens 701 to converge, passes through the filter 704, and then illuminates the laser receiving reflector 702 and is refracted. Finally, it is received by the photoelectric sensor 703. The photoelectric sensor 703 converts the light signal into an electrical signal, and the pen PCB9 calculates the target distance and displays the distance measurement result through the display module 4 and the display window mirror 3.

[0042] Next, when the user needs to write, the pen grip 24 is rotated, which causes the internal negative conductive pen refill lifting pen refill sleeve 22 to rotate. The insulating pen refill sleeve lifting guide pin 2001 is restricted inside the pen refill lifting threaded guide groove 2201. The rotation of the spiral guide groove forces the insulating pen refill sleeve lifting guide pin 2001 to generate a downward thrust, which drives the insulating pen refill lifting pen refill sleeve 20 and the pen refill body 23 to move downward against the elastic force of the pen refill lifting spring 29, so that the pen refill body 23 extends out of the pen barrel.

[0043] Finally, as the pen refill body 23 extends downwards, the lighting component is triggered, and the battery 10 supplies power to the pen PCB9. The current passes sequentially through the spring pin 904, the pen positive terminal conductive female connector 18, the conductive spring 32 at the top of the pen refill, the pen refill body 23, and the pen refill conductive sheet 21, and is transmitted to the pen refill lamp positive terminal conductive spring 28 at the bottom. When the pen refill body 23 is fully extended, the bottom end of the compressed pen refill lamp positive terminal conductive spring 28 abuts against the upper surface of the pen refill lamp PCB positive terminal conductive ring 906 above the light-emitting unit 905, and the positive power supply circuit is connected. The current illuminates the light-emitting unit 905, and the light source is emitted through the pen refill lamp light guide ring 31 to provide illumination for the writing position. When the pen refill body 23 is rotated in the opposite direction after writing is completed, the bottom end of the pen refill lamp positive terminal conductive spring 28 separates from the pen refill lamp PCB positive terminal conductive ring 906 to disconnect the positive power supply circuit, and the lighting automatically turns off.
