Description

Technical Field

[0001] This application relates to the field of occupational safety and health, and in particular to welding masks for flip-up lighting. Background Technology

[0002] To avoid injury from spatter and harmful rays generated during welding operations, operators wear welding masks. However, the viewing window on the welding mask has low light transmittance, making it difficult to visually locate the target area before welding. Therefore, welding masks equipped with light sources have been developed to increase the brightness of the target area before welding.

[0003] For example, Chinese patent document CN202128616U discloses a welding mask with a lighting device, including a mask shell, goggles and a goggle frame for mounting the goggles, and also includes a lighting device disposed on the mask shell. The lighting device includes a power supply, a switch, a control circuit and a light-emitting body disposed on the goggle frame facing the side of the work to be welded.

[0004] In existing technologies, light sources are generally open or even movable relative to the mask to meet lighting needs from more angles. Welding environments are harsh, and such setups can easily damage the light source or cause connection failure with the mask, affecting product lifespan. Furthermore, failing to turn off the light source in a timely manner puts a strain on its power supply; in practice, power outages frequently occur due to operators forgetting to turn off the light, delaying production. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application discloses a welding mask with flip-up lighting, including a mask and a lighting assembly disposed on the mask. The mask is provided with a receiving space, and the lighting assembly includes a lamp holder rotatably mounted in the receiving space and having a light source inside, and a power supply for supplying power to the light source.

[0006] The lamp holder has the following positions on the rotation path:

[0007] In the first position, at least a portion of the lamp holder protrudes from the receiving space, and the light source is exposed to the outside and electrically connected to the power supply to provide illumination;

[0008] In the second position, the lamp holder is located within the receiving space, and the light source and the power supply are disconnected from electrical connection.

[0009] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0010] In one embodiment, the power supply has a first contact that opens toward the receiving space, and the lamp holder has a second contact that is electrically connected to the light source; when the lamp holder is in a first position, the first contact and the second contact are in contact and connected; when the lamp holder is in a second position, the first contact and the second contact are spaced apart.

[0011] In one embodiment, in the front-rear direction of the mask, the lamp holder is wedge-shaped with a front thickness greater than the rear thickness, the second contact is disposed on the rear side of the lamp holder, and the light source is located on the front side of the lamp holder.

[0012] In one embodiment, when the lamp holder is in the second position, the outer surface of the lamp holder is flush with the outer surface of the mask.

[0013] In one embodiment, when the lamp holder is in the second position, the outer surface of the lamp holder encloses the receiving space.

[0014] In one embodiment, the lamp holder is rotatably engaged via a pivot, the light source is located on the front side of the lamp holder, the pivot is located on the rear side of the lamp holder, and the front side of the lamp holder is raised relative to the rear side of the lamp holder to enter the first position.

[0015] In one embodiment, the lighting assembly further includes a base embedded in the mask, the side of the base facing outward forming the receiving space.

[0016] In one embodiment, the base extends through the mask, and the side of the base facing the inside of the mask forms an assembly cavity. The receiving space and the assembly cavity are interconnected through a mating window. The power supply is movably mounted in the assembly cavity and electrically connected to the light source through the mating window.

[0017] In one embodiment, one of the lamp holder and the base is provided with a first positioning member spaced apart, and the other is provided with a second positioning member that cooperates with each of the first positioning members. During the rotation of the lamp holder, the second positioning member moves between each of the first positioning members to position the relative position of the lamp holder and the base.

[0018] In one embodiment, a first limiting member and a second limiting member are provided on the front side of the lamp holder, and the first limiting member and the second limiting member are spaced apart in the rotation direction of the lamp holder;

[0019] The base is provided with a third limiting member. When the lamp holder is in the second position, the first limiting member is close to the upper surface of the third limiting member. When the lamp holder is in the first position, the second limiting member is close to the lower surface of the third limiting member.

[0020] The technical solution disclosed in this application sets the light source by rotating the lamp holder, which can protect the light source while ensuring the adaptability of multi-angle cover and improve the stability of the product; at the same time, the electrical connection between the light source and the power supply is linked to the position of the lamp holder, and automatically cuts off the connection between the light source and the power supply at the appropriate time, saving energy, improving the user experience, and ensuring production efficiency.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0042] 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 application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] The welding mask in this application defines an outer side exposed to the outside and an inner side for cooperation via a mask 100. The mask 100 has a viewing window 110 for observing the target position, and the viewing window 110 has a fixed-color or automatically color-changing light-blocking visor to protect the wearer. Several lighting components 200 are movably mounted on the mask 100. Each lighting component 200 includes at least one light source 211 capable of projecting light onto the target position to provide visual guidance during breaks in welding operations. The lighting components 200 can automatically turn on or off in response to the arc light of the welding operation to save energy, or they can adaptively turn on or off or adjust the power of the light source 211 in response to ambient brightness.

[0044] To improve the user experience of the lighting assembly 200, this application makes improvements to the lighting assembly 200 itself and the mating relationship between the lighting assembly 200 and the mask 100, as detailed in the appendix. Figure 1 and attached Figure 2 In the illustrated embodiment, this embodiment discloses a welding mask with flip-up lighting, including a mask 100 and an lighting assembly 200 disposed on the mask 100. The mask 100 has a receiving space 120, which can be provided by the mask 100 itself or by a component mounted on the mask 100. The lighting assembly 200 includes a lamp holder 210 mounted within the receiving space 120 and having a light source 211 inside, and a power supply 220 for supplying power to the light source 211. The receiving space 120 can provide protection for the lamp holder 210 to improve the working environment of the lighting assembly 200. In the lighting path, the sidewalls forming the receiving space 120 can be transparent to allow the light source 211 of the lighting assembly 200 to project light onto the target area; see also the attached diagram. Figure 5 To be continued Figure 8 As shown, the lamp holder 210 is rotatably mounted within the receiving space 120, and the lamp holder 210 has the following positions in the rotation path:

[0045] First position (e.g., attached) Figure 8 As shown), at least a portion of the lamp holder 210 protrudes from the receiving space 120, and the light source 211 is exposed to the outside and electrically connected to the power supply 220 to provide illumination;

[0046] Second position (e.g., attached) Figure 5As shown, the lamp holder 210 is located within the housing space 120, and the light source 211 and the power supply 220 are disconnected from each other.

[0047] The rotating lighting assembly 200 provides a wider range of material options for the mask 100 and its mating parts, not limited to transparent materials, and also provides a basis for the light source control of the lighting assembly 200.

[0048] There are various ways to electrically connect and disconnect the light source 211 and the power supply 220. For example, in one embodiment, the light source 211 and the power supply 220 are electrically connected in the circuit via a controllable switch. The controllable switch responds to different positions of the lamp holder 210. Further, the controllable switch is a magnetic switch, and the lamp holder 210 or the lamp housing is provided with a magnet for changing the magnetic switch. Further still, the controllable switch can also be a sound-activated switch, a light-activated switch, a signal-based electronic switch, etc. For example, see attached... Figure 5 and attached Figure 8 In the embodiment shown, the power supply 220 is provided with a first contact 221 that opens toward the receiving space 120, and the lamp holder 210 is provided with a second contact 212 that is electrically connected to the light source 211; when the lamp holder 210 is in the first position, the first contact 221 and the second contact 212 are in contact and connected; when the lamp holder 210 is in the second position, the first contact 221 and the second contact 212 are spaced apart.

[0049] Furthermore, the control of the light source 211 in this application is not limited to the electrical connection between the light source 211 and the power supply 220. For example, in one embodiment, the electrical connection between the light source 211 and the power supply 220 is a necessary but not sufficient condition for the operation of the light source 211. The light source 211 is controlled by the control circuit 213, which controls the operation or shutdown of the light source 211 based on the connected ambient light sensor 214 and arc light sensor 215. The control logic and circuit implementation of the control circuit 213 can be implemented in conjunction with existing technology, and will not be described in detail here.

[0050] For details regarding the structure of lamp holder 210, please refer to the attached document. Figure 2 As shown, in the front-rear direction of the face mask 100, the lamp holder 210 is wedge-shaped with a front thickness greater than the rear thickness. The second contact 212 is located on the rear side of the lamp holder 210, and the light source 211 is located on the front side of the lamp holder 210. The lamp holder 210 is rotatably engaged via a pivot 216, which is located on the rear side of the lamp holder 210. Further, refer to the attached diagram. Figure 9 To be continued Figure 11As shown, the lamp holder 210 has an upper housing 217 and a lower housing 218 that interlock. The light source 211, the control circuit 213, and the contact substrate 2121 with the second contact 212 are all disposed in the lower housing 218. The upper surface of the upper housing 217 is exposed to the outside of the mask 100 and has an operation hole 2171. The control circuit 213 has an operation button 2131 exposed to the operation hole 2171 to control the working state of the lighting assembly 200. The upper housing 217 and the lower housing 218 surround and constrain the light-transmitting plate 219, which is located in front of the light source 211. When the lamp holder 210 is in the first position, the light-transmitting plate 219 faces the target area; when the lamp holder 210 is in the second position, the light-transmitting plate 219 faces the side wall of the receiving space 120.

[0051] Regarding the fit between lamp holder 210 and other components, please refer to the attached document. Figure 1 In the illustrated embodiment, with the lamp holder 210 in the second position, the outer surface of the lamp holder 210 is flush with the outer surface of the face mask 100. In this embodiment, the receiving space 120 is located above the viewing window 110, i.e., the forehead of the face mask 100. Further, with the lamp holder 210 in the second position, the outer surface of the lamp holder 210 encloses the receiving space 120 to protect the components within the receiving space 120. In another embodiment, with the lamp holder 210 in the second position, it encloses the face mask 100 to provide protection. Regarding the manner of rotation of the lamp holder 210, refer to the attached drawing. Figure 8 In the illustrated embodiment, the front side of the lamp holder 210 is raised relative to the rear side to enter a first position. In this configuration, the rotation angle of the lamp holder 210 is small and easy to control. Specifically, the rotation angle range of the lamp holder 210 is 5 degrees to 60 degrees. To facilitate operation of the lamp holder 210, the attached... Figure 9 In the illustrated embodiment, the base 230 is provided with an opening groove 2334 that avoids the side edge of the upper surface of the lamp holder 210. The opening groove 2334 is retracted relative to the side edge of the lamp holder 210 to expose the side edge of the lamp holder 210, so as to facilitate the driving of the lamp holder. In the appendix Figure 12 In the illustrated embodiment, the lamp holder 210 is provided with a drive edge 2174 that protrudes into the receiving space. The drive edge 2174 extends to the outside of the receiving space and then abuts against the outside of the face mask 100 and / or the base 230 to form an opening gap. The user can drive the lamp holder 210 by applying force to the drive edge 2174.

[0052] To facilitate the interaction between the lamp holder 210, the lampshade 100, and the power supply 220, please refer to the attached document. Figure 2 In the illustrated embodiment, the lighting assembly 200 further includes a base 230 embedded in the face mask 100, the side of the base 230 facing outward forming a receiving space 120. (See attached drawing.) Figure 6 and attached Figure 11In the illustrated embodiment, the base 230 penetrates the face mask 100, and the side of the base 230 facing the inner side of the face mask 100 forms an assembly cavity 231. The receiving space 120 and the assembly cavity 231 are interconnected through a mating window 232. The power supply 220 is movably mounted in the assembly cavity 231 and electrically connected to the light source 211 through the mating window 232. A mating member 2311 for holding the power supply 220 within the assembly cavity is provided on the side wall of the assembly cavity 231.

[0053] In the appendix Figure 11 In the illustrated embodiment, the power supply 220 includes a boss 222 that mates with the assembly cavity 231 and a housing 223 disposed below the boss 222. The side edge of the boss 222 is provided with spring tabs 224 that are positioned relative to the mating member 2311. Multiple spring tabs 224 are provided and spaced apart. When each spring tab 224 is forced to move closer together, it separates from the mating member 2311 to release the connection between the power supply 220 and the assembly cavity 231. This arrangement provides a stable connection and facilitates quick release when needed.

[0054] In the appendix Figure 14 In the illustrated embodiment, the mating component 2311 is a slide rail that opens outward toward the assembly cavity 231, and the slide rail has an elastic segment 2312 that protrudes inward toward the slide rail. The power supply 220 includes a boss 222 that mates with the assembly cavity 231 and a housing 223 disposed below the boss 222. The side edge of the housing 223 has a slide rail 225 that slides and engages with the slide rail formed by the mating component 2311. The slide rail 225 engages with the slide rail, allowing the power supply 220 and the base 230 to move only in the extension direction of the slide rail. The slide rail 225 has multiple positioning protrusions 2251, and the positioning protrusions 2251 are smoothly transitioned between each other. When the power supply 220 moves relative to the base 230 to a preset position, the elastic segment 2312 is precisely located at two positioning protrusions 2251 to achieve positioning. This configuration simplifies the operation process of installing and separating the power supply 220. There is no need to operate locking or unlocking components; simply driving the power supply 220 to move relative to the base 230 is sufficient to install or separate the power supply.

[0055] In the mutual cooperation between the lamp holder 210 and the base 230, one of the lamp holder 210 and the base 230 is provided with first positioning members spaced apart, and the other is provided with second positioning members that cooperate with each of the first positioning members. During the rotation of the lamp holder 210, the second positioning members move between the first positioning members to position the relative positions of the lamp holder 210 and the base 230. (See attached diagram) Figure 2 Appendix Figure 3 and appendix Figure 11In the illustrated embodiment, the first positioning element is a positioning protrusion 2351 located near the shaft hole 235 that mates with the rotating shaft 216, and the second positioning element is a positioning rib 2161 located near the rotating shaft 216. In different embodiments, the positioning protrusion 2351 and the positioning rib 2161 can also be interchanged. In the embodiment where the lamp holder 210 has an upper housing 217 and a lower housing 218, the positioning rib 2161 is located on the upper housing 217, and the rotating shaft 216 is located on the lower housing 218. During the assembly of the upper housing 217 and the lower housing 218, the positioning rib 2161 is positioned near the rotating shaft 216.

[0056] In another embodiment, a first limiting member and a second limiting member are provided on the front side of the lamp holder 210, and the first limiting member and the second limiting member are spaced apart in the rotation direction of the lamp holder 210.

[0057] A third limiting member is provided on the base 230. When the lamp holder 210 is in the second position, the first limiting member is close to the upper surface of the third limiting member; when the lamp holder 210 is in the first position, the second limiting member is close to the lower surface of the third limiting member. (See attached diagram) Figure 6 Appendix Figure 8 and appendix Figure 11 As shown, the first and second limiting members are the upper flange 2172 and lower flange 2181 on the front side of the lamp holder 210, respectively, and the third limiting member is the positioning edge 2331 extending from the base 230 toward the receiving space 120. In addition to the front limiting, the base 230 can also limit the rear side of the lamp holder 210. (See attached diagram) Figure 6 and attached Figure 11 As shown, the lamp holder 210 has a platform portion 2173 on its rear side, and the base 230 has an abutment edge 2332. When the lamp holder 210 is in the second position, the platform portion 2173 is close to the abutment edge 2332; or the platform portion 2173 abuts against the abutment edge 2332. Besides positioning, the platform portion 2173 can also perform a clearance function. For example, in the attached... Figure 13 In the embodiment shown, the platform portion 2173 has an arc-shaped outer surface, and during the movement of the lamp holder 210, the platform portion 2173 is always spaced apart from the abutment edge 2332.

[0058] In embodiments where the base 230 is not provided, the mating details on the base 230 can also be correspondingly provided on the component used to form the receiving space 120 and mate with the lamp holder 210 to achieve the above-mentioned technical effects.

[0059] Reference Appendix Figure 11As shown, the base 230 includes an upper body 233 and a lower body 234 located on both sides of the face mask 100, respectively. The upper body 233 and the lower body 234 clamp the face mask 100 from both sides for positioning. The side of the lower body 234 facing outward forms a receiving space 120, and the side facing inward forms an assembly cavity 231. The upper body 233 is partially open to avoid the receiving space 120. The upper body 233 also has a reinforced sidewall 2333 that extends into the receiving space 120 to abut against the sidewall of the lower body 234. In this embodiment, the upper body 233 and the lower body 234 are stably connected by positioning posts surrounding the receiving space 120 and fasteners. Figure 14 In the assembly, the front sides of the upper seat 233 and the lower seat 234 are fastened together by a snap-fit ​​236, and the rear sides of the upper seat 233 and the lower seat 234 are connected by a positioning post and fasteners. The cooperation between the snap-fit ​​236 and the fasteners can improve assembly efficiency while ensuring assembly accuracy. The fasteners can ensure the strength of the shaft hole to provide stable constraint on the movement of the lamp holder. Therefore, when the position of the shaft hole changes, the setting of the fasteners can also be adjusted accordingly.

[0060] The upper seat 233 and the lower seat 234 each form a half shaft hole 235, which are joined together during assembly to form a complete shaft hole 235. This arrangement facilitates the assembly of the components. For example, in one embodiment, the lamp holder 210 is first installed into the receiving space 120 of the lower seat 234, and then the upper seat 233 and the lower seat 234 are assembled to achieve assembly.

[0061] The following is in conjunction with the appendix Figure 5 To be continued Figure 8 The working process of the welding mask with flip-up lighting in this application is illustrated by example:

[0062] When the wearer needs the lighting component 200 to work, the lamp holder 210 is driven to rotate so that the lamp holder 210 enters the first position (e.g., the front edge of the lamp holder 210 is raised relative to the rear edge). The light source 211 is exposed to the outside world and electrically connected to the power supply 220. The light source 211 can work according to preset conditions under the control of the control circuit 213. The projection light path 2111 of the light source 211 is parallel or nearly parallel to the normal of the plane where the viewing window 110 is located (e.g., the included angle A1 between the two is in the range of 0 degrees to 30 degrees) to ensure that the light source 211 is projected into the area where the wearer's line of sight is located.

[0063] When the wearer does not need the lighting component 200 to operate, the light source can be turned off via the control circuit 213; alternatively, the lamp holder 210 can be rotated in the opposite direction to enter a second position (e.g., the leading edge of the lamp holder 210 falls relative to the trailing edge), and the lamp holder 210 enters the receiving space 120. The light source 211 and power supply 220 are electrically disconnected to avoid energy consumption, and the various parts of the lighting component 200 are enclosed in a constrained space to prevent damage. At this time, the outer surface of the face mask 100 is flat, reducing the safety hazards caused by protruding parts snagging in the production environment. (See attached...) Figure 5 In the projection path 2111 of the light source 211 intersects the normal of the plane containing the window 110 (for example, the included angle A2 between the two ranges from 20 degrees to 70 degrees).

[0064] Other details regarding the setup of the mask 100 can be implemented using existing technologies and will not be elaborated here.

[0065] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0066] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
