Description

Technical Field

[0001] This utility model relates to the field of welding cap technology, specifically a welding cap with adaptive light adjustment function. Background Technology

[0002] As is well known, welding, as a core process for metal joining, is widely used in industries such as construction, shipbuilding, and machining. However, the high-intensity arc light generated during welding, which includes ultraviolet, infrared, and strong visible light, can not only cause temporary blindness and photokeratitis in welders, but also interfere with their operation due to the glaring light, affecting welding accuracy and quality.

[0003] Traditional welding protective equipment mostly uses fixed light-shielding lenses, which have a fixed light transmittance and cannot be dynamically adjusted according to factors such as welding current and working environment. For example, when the welding current is low, a high light-shielding lens will result in a dim field of vision, making it difficult to observe the weld. When the welding current increases, a low light-shielding lens cannot effectively block strong light, threatening the welder's visual health.

[0004] Although some automatic light-changing welding helmets have photosensitive color-changing functions, they cannot achieve personalized lighting adaptation according to different welding materials and process parameters. This makes it difficult to achieve fast and accurate lighting adjustment, causing welders to frequently remove and put on the welding helmet during welding intervals, reducing work efficiency, increasing the risk of injury, and limiting the improvement of welding quality. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a welding cap with adaptive illumination adjustment function.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a welding cap with adaptive light adjustment function, comprising a protective cap, an opening on the front side of the protective cap, an adjustment box at the opening, adjustment components on both sides of the adjustment box, an adjustment lens inside the adjustment box, the adjustment lens being connected to the adjustment components and adapted to the adjustment box, a monitor on the upper side wall of the adjustment box, the monitor being signal-connected to the adjustment lens and the adjustment components, and a battery assembly for power supply at the upper end of the welding cap.

[0009] To achieve smooth displacement of the adjustable lens, this invention improves upon the following: the adjusting assembly includes a support box, a threaded rod, a sliding rod, and sliding blocks. The support box is symmetrically arranged at both ends of the adjusting box. The threaded rod and the sliding rod are arranged parallel to each other within the support box. The sliding blocks are symmetrically arranged. The threaded rod passes through one of the sliding blocks and is threadedly connected to it. The sliding rod passes through the other sliding block and is slidably connected to it. The sliding blocks are fitted against and slidably connected to the inner wall of the support box. The side wall of the adjusting box is provided with symmetrical through holes. Both sides of the adjusting lens pass through the through holes and are connected to the sliding blocks.

[0010] In order to provide power to the adjustment component and realize automated control, the present invention is improved in that: a motor is provided on the side wall of one of the support boxes, and the threaded rod passes through the support box and is connected to the output end of the motor.

[0011] In order to adjust the brightness in real time according to the intensity of the welding arc light, the present invention has the following improvements: the adjustment lens is an intelligent liquid crystal photochromic lens with built-in electrochromic material, which can quickly change the light transmittance according to the received electrical signal, achieve a response speed of 0.1 seconds, and accurately adapt to the changes in the intensity of the welding arc light.

[0012] In order to adjust the tightness according to the wearer's head shape and needs, the present invention is improved by providing an adjustable elastic band on the back of the protective cap.

[0013] To prevent sparks, molten metal slag, and other flying debris from hitting the face or neck, this invention features an improvement: a protective plate is provided at the lower end of the protective cap.

[0014] In order to protect the head from impacts from flying debris and ensure head safety, the present invention is improved in that: both the protective cap and the protective plate are made of high-strength carbon fiber material, which has both lightweight and impact resistance.

[0015] In order to comprehensively capture the illumination information of the welding area, the present invention has the following improvements: the monitor is a multispectral light intensity sensor, which can monitor the ultraviolet, infrared and visible light intensity of the welding area in real time, and accurately analyze the illumination data through a built-in algorithm.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a welding cap with adaptive illumination adjustment function, which has the following beneficial effects:

[0018] This welding helmet, equipped with adaptive light adjustment, features a monitor that uses a multispectral light intensity sensor to monitor the intensity of ultraviolet, infrared, and visible light in the welding area in real time. It accurately identifies the intensity and spectral characteristics of the welding arc light. Combined with an intelligent LCD photochromic lens containing built-in electrochromic material, it can achieve a transmittance adjustment response of 0.1 seconds. Whether it is the strong light impact caused by a sudden change in welding current or the low light environment in the welding gap, the lens can quickly switch to a suitable brightness state. This effectively blocks harmful light to protect the welder's eyesight and ensures a clear field of vision throughout the operation, avoiding the impact on work efficiency caused by frequently removing and putting on the welding helmet.

[0019] Equipped with an adjustment component, when the motor drives the threaded rod to rotate, the sliding block connected to it converts the rotational motion into linear displacement. The sliding rod provides guidance and support for another sliding block, ensuring a smooth and wobbly adjustment process. The symmetrical layout ensures that the adjustment lens is subjected to uniform force, effectively preventing the lens from tilting or getting stuck. Combined with the through-hole limit on the side wall of the adjustment box, precise control of the lens position can be achieved, ensuring the stability and long-term reliability of the illumination adjustment and adapting to the high-frequency adjustment needs in welding operations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figure 1-4 A welding cap with adaptive light adjustment function includes a protective cap 1. The protective cap 1 has an opening on its front side, and an adjustment box 5 is provided at the opening. Adjustment components are provided on both sides of the adjustment box 5. An adjustment lens 8 is provided inside the adjustment box 5. The adjustment lens 8 is connected to the adjustment components and is adapted to the adjustment box 5. A monitor 4 is provided on the upper side wall of the adjustment box 5. The monitor 4 is signal connected to the adjustment lens 8 and the adjustment components. A battery component 3 for power supply is provided at the upper end of the welding cap. The adjustment lens 8 is a smart liquid crystal photochromic lens with built-in electrochromic material. It can quickly change the light transmittance according to the received electrical signal, achieving a response speed of 0.1 seconds and accurately adapting to changes in welding arc light intensity. The monitor 4 is a multispectral light intensity sensor that can monitor the ultraviolet, infrared, and visible light intensity of the welding area in real time and accurately analyze the light data through a built-in algorithm. An adjustable elastic band 9 is provided on the rear side of the protective cap 1.

[0029] During use, before putting on the welding helmet, the welder presses the power switch, and the battery pack 3 supplies power to the equipment. Then, the welder adjusts the elastic band 9 on the back of the protective helmet 1 to make the helmet fit snugly against their head. At this time, the adjustment box 5 is facing the welder's line of sight, and the adjustment lens 8 is in its initial position, providing a reference for subsequent lighting adjustments.

[0030] After the welding operation starts, the multispectral light intensity sensor inside the monitor 4 works continuously, capturing ultraviolet, infrared, and visible light intensity data of the welding area at millisecond frequencies. The sensor analyzes the spectral information through a built-in algorithm, distinguishing between welding arc light and ambient light, and accurately determining whether the current light intensity has reached a threshold that threatens eyesight. Then, the collected light data is compared with internal preset parameters (such as safe light intensity range and adaptable transmittance for different welding processes). If a sudden change in arc light intensity is detected (such as a sudden increase in welding current), the monitor 4 immediately generates a control command, which is sent to the adjustment component and the adjustment lens 8 through the signal transmission module.

[0031] When a smart photochromic liquid crystal lens receives an electrical signal, the molecular structure of the internal electrochromic material instantly rearranges under the influence of an electric field. For example, when the arc light intensifies, the electrical signal causes the material to absorb more light, rapidly reducing the lens's transmittance and blocking strong light. When the light weakens during welding, the electrical signal changes direction, the material structure adjusts, and the lens's transmittance increases, ensuring a clear view for the welder. The entire response process takes only 0.1 seconds, far faster than the passive response speed of traditional photochromic lenses.

[0032] Simultaneously, the monitor 4 sends a position adjustment command to the adjustment component, causing the adjustment lens 8 to move back and forth, adjusting its distance from the welder's eyes. For example, when welding requires delicate operations, the lens automatically moves forward to reduce the viewing distance and improve clarity; when the arc light is strong, the lens moves back appropriately to expand the field of vision and enhance the protective effect.

[0033] During the adjustment process, monitor 4 continuously monitors changes in illumination and lens status. If a deviation is detected between the actual light transmittance or lens position and the command, a correction signal is immediately sent to ensure adjustment accuracy.

[0034] Battery component 3 adopts a low-power design. During non-welding periods or periods of stable light, the equipment automatically enters a sleep mode, reducing the operating frequency of the sensors and motor 7 and extending the battery life. When the battery level is lower than the threshold, the welding cap will remind you to replace the battery through vibration or a prompt sound.

[0035] In practical use, it is necessary to achieve smooth displacement of the adjustment lens 8 to ensure the stability and reliability of light adjustment. To meet the above requirements, in this embodiment, the adjustment assembly includes a support box 6, a threaded rod 12, a sliding rod 10, and a sliding block 11. The support box 6 is symmetrically arranged at both ends of the adjustment box 5. The threaded rod 12 and the sliding rod 10 are arranged parallel to each other inside the support box 6. The sliding blocks 11 are symmetrically arranged. The threaded rod 12 passes through one of the sliding blocks 11 and is threadedly connected to it. The sliding rod 10 passes through the other sliding block 11 and is slidably connected to it. The sliding block 11 is fitted against and slidably connected to the inner wall of the support box 6. The side wall of the adjustment box 5 is provided with symmetrical through holes. Both sides of the adjustment lens 8 pass through the through holes and are connected to the sliding block 11. A motor 7 is provided on the side wall of one of the support boxes 6. The threaded rod 12 passes through the support box 6 and is connected to the output end of the motor 7.

[0036] After receiving the signal, the motor 7 starts and drives the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to one of the sliding blocks 11, the rotational motion is converted into linear displacement. The sliding block 11 moves along the axial direction of the threaded rod 12. The other sliding block 11 is slidably connected to the sliding rod 10, which plays a guiding and stabilizing role and prevents the lens from tilting during the adjustment process. The two sliding blocks 11 move synchronously and drive the adjustment lens 8 to move back and forth through the through hole on the side wall of the adjustment box 5, adjusting its distance from the welder's eyes.

[0037] In actual use, it is necessary to block the sparks, molten metal slag and other spatter generated during the welding process to prevent them from splashing onto the face or neck. In order to meet the above requirements, in this embodiment, the lower end of the protective cap 1 is provided with a protective plate 2.

[0038] In practical use, it is necessary to have both high strength and impact resistance to resist the impact of spatter, ensure head safety, and extend the service life of the welding helmet. In order to meet the above requirements, in this embodiment, both the protective helmet 1 and the protective plate 2 are made of high-strength carbon fiber material, which has both lightweight and impact resistance.

[0039] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
