Description

Technical Field

[0001] The present invention relates to the technical field of safety helmets, and in particular to a safety helmet and a safety helmet system. Background Art

[0002] Safety helmets are essential personal protective equipment in industrial production and other high-risk working environments. They are widely used in industrial fields such as construction, mining, and electricity. Their main function is to protect the head from damage caused by external forces such as falling objects and impacts. The structure of a safety helmet mainly includes a helmet shell, a hat lining (such as a top strap, a hat hoop, and a chin strap), and other components. The helmet shell is the key component to withstand and disperse impact forces.

[0003] As the working environment becomes more complex and diversified, more and more helmets need to be equipped with various functional accessories, such as lighting equipment (headlights, flashlights), warning equipment (reflective strips, warning lights), communication equipment (walkie-talkies, headphones), and even cameras. The effective fixation of these accessories is crucial to ensure work safety and improve work efficiency. Therefore, how to achieve reliable fixation of accessories without affecting the protective performance of the helmet has become a technical problem that needs to be solved urgently.

[0004] At present, the fixing methods of helmets and accessories include screw fixing, strap fixing, magnetic fixing and adhesive fixing, but all of them have significant defects:

[0005] Screw fixing: Industrial safety helmet standards strictly prohibit drilling holes or introducing metal parts on the helmet shell. Drilling will damage the integrity of the helmet body, weaken its impact resistance, cause stress concentration, and greatly reduce the absorption and dispersion of impact energy; and the introduction of metal accessories may accelerate the aging of the helmet body due to problems such as conductivity and material compatibility, and even cause secondary injury risks due to collisions during operation.

[0006] Strap fixation: Since the surface of the helmet is mostly smooth and curved and has no fixed anchor points, the straps can easily slip due to external force or movement of people, causing the accessories to shift in position or even fall off. Especially in intense activities or vibration environments, the reliability of fixation is difficult to guarantee, affecting the continuity and safety of the operation.

[0007] Magnetic / adhesive fixation: Magnetic devices rely on the strength of the magnetic force, while adhesives are limited by the durability of the adhesive material. In complex operating environments, dust, oil, and corrosive substances can easily weaken the magnetic or adhesive effect, causing accessories to fall off accidentally. In addition, high or low temperature environments may further reduce the performance of the adhesive and affect the stability of the equipment.

[0008] In summary, the existing methods of fixing helmet accessories all have defects to varying degrees, and it is difficult to simultaneously meet the requirements of firmness, safety, convenience, applicability, etc. Therefore, it is urgent to develop a new type of helmet structure to overcome the shortcomings of the existing technology and provide workers with safer, more reliable and efficient personal protective equipment.

[0046] Embodiment 1

[0047] See also Figure 1-Figure 9 , shown is a safety helmet in the first embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown. The safety helmet provided by the embodiment of the present invention includes a helmet shell 10, a top strap 20 connected and fixed to the helmet shell 10, a hat hoop 30 connected and fixed to the top strap 20, and a chin strap 40 connected and fixed to the hat hoop 30;

[0048] The outer surface of the cap shell 10 is provided with a first fixing member 11 and a second fixing member 12 which are integrally injection-molded and symmetrically distributed front and back along the central axis;

[0049] The first fixing member 11 includes a slot-shaped structure consisting of two parallel first slots 111 and second slots 112 respectively used to fix different lighting fixtures;

[0050] The second fixing member 12 includes two buckles for fixing the cable which are symmetrically distributed along the central axis, and symmetrical slide grooves 121 are respectively provided on the side walls adjacent to the two buckles. The slide grooves 121 arranged between the two buckles together form a clamping structure for clamping the handle of the warning lamp.

[0051] Among them, in one embodiment of the present invention, the cap shell 10 is the main part of the helmet, and is made of high-strength, impact-resistant engineering plastics (such as PC, ABS, etc.) through an injection molding process. The outer shape of the cap shell 10 is hemispherical or similar, and the interior is hollow to accommodate the wearer's head. The inner surface of the cap shell 10 is smooth, and a plurality of arc-shaped fixing grooves can be provided for connecting with the top strap 20. The outer surface of the cap shell 10 is provided with a first fixing member 11 and a second fixing member 12. The first fixing member 11 is connected to the outer surface of the cap shell 10 through an integrated injection molding process, and is located at the front of the cap shell 10 (along the central axis of the helmet).

[0052] The first fixing member 11 is a groove-shaped structure, including two parallel first and second slots 111 and 112. The first and second slots 111 and 112 are sequentially arranged on the outer surface of the helmet shell 10, and the opening of the first slot 111 is larger than the opening of the second slot 112. Specifically, the first slot 111 is located on the inner side and has a larger opening, and is used to fix the rotating structure of the lighting headlight. Fig.10 and Fig.11As shown, the rotating structure is usually a plastic part with a pivot, around which the headlamp can rotate to adjust the illumination angle, and an elastic buckle is provided on the rotating structure, which is used to undergo elastic deformation during the insertion and removal of the elastic buckle in the first slot 111. Further, a receiving notch 113 is provided at the bottom of the first slot 111, which is used to accommodate the elastic buckle on the rotating structure of the headlamp to increase the fixing stability. At this time, during the insertion of the rotating structure of the headlamp into the first slot 111, the elastic buckle first undergoes elastic deformation, until the rotating structure is inserted into the first slot 111, the elastic buckle is accommodated in the receiving notch 113 and recovers the deformation, thereby achieving the engagement and fixation of the rotating structure of the headlamp with the first slot 111. The second slot 112 is located on the inner side, with a smaller opening, and is used to fix the cap hook of the cordless lamp. The cap hook of the cordless lamp is usually a metal or plastic hook that can be inserted into the second slot 112. It should be pointed out that the opening of the first card slot 111 is larger than the opening of the second card slot 112. This is mainly because the larger opening of the first card slot 111 can provide sufficient space for the deformation of the elastic buckle during the insertion and removal process. The cordless lamp may be subjected to greater vibration or impact during use. In this case, the smaller opening of the second card slot 112 can form a "stuck" effect, thereby more tightly restraining the cap hook of the cordless lamp to prevent it from shaking or falling off in the second card slot 112. At the same time, the opening of the first card slot 111 is larger than the opening of the second card slot 112, which makes it easier to set the accommodating notch 112 for accommodating the elastic buckle and to effectively press the elastic buckle to remove the lighting headlamp.

[0053] Furthermore, the first fixing member 11 is also provided with a reinforcement structure 114 connected to the outer surface of the cap shell 10 and the groove structure respectively. The reinforcement structure 114 is located between the outer surface of the cap shell 10 and the side wall of the groove structure in the first fixing member 11. The reinforcement structure 114 is usually provided with reinforcing ribs or thickened, so as to improve the strength and anti-deformation ability of the first fixing member 11. Figure 8 As shown, the reinforcement structure 114 is a reinforcing rib connecting the outer surface of the cap shell 10 and the first slot 111 .

[0054] Among them, in one embodiment of the present invention, the second fixing member 12 is integrally injection molded with the cap shell 10, and is located at the rear of the outer surface of the cap shell 10. Two buckles are symmetrically distributed along the central axis, and each buckle has an opening, which is roughly "C" shaped, for clamping the cable rope or other linear accessories. The two buckles are arranged perpendicular to the outer surface of the cap shell 10 and tilted upward. At the same time, the rear of the helmet is usually the position of the back of the wearer's head. At this time, the buckle is tilted upward, which can better conform to the curve of the head, so that the fixed cable rope or other accessories fit the head better, reducing the discomfort and shaking when wearing. And when the cable rope is subjected to tension, the inclined buckle can decompose the tension into upward and backward components. The upward component helps to fix the helmet more tightly on the head and prevent the helmet from tilting back or falling off due to tension. At the same time, the inclined design makes the opening of the buckle face obliquely upward, which is more convenient for the wearer to clamp or remove the cable rope, especially when wearing gloves or inconvenient operation. Each buckle is provided with a slide groove 121 on one side close to the central axis, and the slide groove 121 is also arranged to be inclined upward. The slide groove 121 arranged between the two buckles together forms a complete clamping structure, which is used to clamp the handle of the warning lamp, facilitating the insertion and removal of the handle of the warning lamp. At the same time, the slide groove 121 arranged to be inclined upward can guide the warning lamp to irradiate upward, thereby expanding the warning range and improving safety. Further, refer to Fig. 9 As shown, the top opening of the slide groove 121 is larger than the bottom opening of the slide groove 121, forming an inverted trapezoidal structure, which is convenient for inserting the handle of the warning lamp and preventing it from accidentally slipping out. Furthermore, the slide groove 121 and the handle of the warning lamp are respectively provided with a first limiting structure (not shown) and a second limiting structure that cooperate with each other, which are used to limit the handle of the warning lamp and prevent it from falling off, and by providing an inverted trapezoidal structure, the handle of the warning lamp can be gradually clamped and finally locked. The side wall of the slide groove 121 is provided with a second limiting groove or a second limiting protrusion or a second magnetic attraction member corresponding to the first limiting protrusion or the first limiting groove or the first magnetic attraction member provided on the handle of the warning lamp. Specifically, the handle of the warning lamp has a first limiting protrusion, and a second limiting groove (not shown) is provided on the inner wall of the slide groove 121. After the handle of the warning lamp is inserted into the second fixing member 12 through the slide groove 121, the first limiting protrusion and the second limiting groove cooperate with each other to play a role in limiting and preventing falling off. Of course, the first limiting structure and the second limiting structure can also be a second limiting protrusion and a first limiting groove that cooperate with each other, or a first magnetic attraction member and a second magnetic attraction member that attract each other, which are not specifically limited here.

[0055] In one embodiment of the present invention, a plurality of fixing grooves with arc-shaped inner surfaces are provided on the inner side of the cap shell 10, and a limiting portion for limiting the top band 20 is provided on the inner side wall of the fixing groove; the end portion of the top band 20 is forked with a fixing portion that is arranged obliquely and matches each fixing groove and a fixing hole for connecting and fixing the cap hoop 30, and a limiting groove that engages with the limiting portion is provided on the fixing portion. Figure 5As shown, the inner side of the cap shell 10 is provided with four first fixing grooves 13 symmetrically distributed in the circumferential direction, and the left and right sides of the cap shell 10 are provided with four second fixing grooves 14 symmetrically distributed, wherein the four first fixing grooves 13 are symmetrically distributed in the circumferential direction along the bottom edge of the cap shell 10 (for example, one each in the front, back, left and right), and the four second fixing grooves 14 are symmetrically distributed in the middle of the left and right sides of the cap shell 10 (for example, two each in the left and right), so by providing multiple fixing grooves, the connection strength between the cap shell 10 and the top band 20 can be effectively increased. Further, in one embodiment of the present invention, the fixing groove has an arc-shaped inner surface, wherein the bottom is also an arc surface (which can be a circular arc, an elliptical arc or other smooth curve). The inner wall of the fixing groove is inclined toward the inside of the cap shell 10, that is, the thickness of the bottom inner wall of the fixing groove (the side close to the inside of the cap shell 10) is greater than the thickness of the top inner wall (the side close to the outer surface of the cap shell 10). On the one hand, this inclined design is to match the overall narrow shape of the helmet, which is wide at the bottom. At the same time, the inner wall at the bottom of the fixing groove is thicker, which means that the limit part can be longer and thicker, thereby providing a larger contact area and higher strength, and enhancing the stability of the connection. On the other hand, it also facilitates the installation and demoulding of the fixing part. The inclined inner wall provides a demoulding slope for the mold during the injection molding process, making it easier to remove the cap shell 10 from the mold. If the inner wall is vertical, it may cause demoulding difficulties and even damage the product. At the same time, in conjunction with the inclined setting of the fixing part of the top band 20 and the body of the top band 20, when the fixing part is removed, the fixing part moves toward the top of the fixing groove, and the inner wall at the bottom of the fixing groove is thicker and forms an inclination to achieve cooperation with the fixing part of the top band 20. Further, the top of the fixing groove (i.e., the opening) extends out of the inner surface of the cap shell 10 (i.e., the connection between the cap shell 10 and the brim), providing sufficient space and travel for the installation of the fixing part of the top band 20. If the fixing groove does not extend but is flush with the inner surface of the cap shell 10, the fixing part cannot be inserted directly and quickly and effectively. Therefore, the end of the fixing groove extending out can play a certain guiding role during installation, making it easier to align the fixing groove. At the same time, when installing the fixing part of the top band 20, it is necessary to first insert it at an angle, and then move the fixing part through the angle between the fixing part and the top band 20, so that the limiting groove and the limiting part are finally engaged. Therefore, the extension of the end of the fixing groove provides the necessary travel space for the movement of the fixing part. At the same time, the end of the fixing groove extends out of the inner surface of the cap shell 10, so that the stress transmitted to the cap shell 10 by the top band 20 can be dispersed to a certain extent, avoiding stress concentration at the root of the fixing groove. Further, the depth of the fixing groove (along the radial direction of the cap shell 10) is greater than the length of the fixing groove (along the circumferential direction of the cap shell 10), and the bottom of the fixing groove is an arc surface. At this time, the deeper fixing groove can provide a stronger pull-off resistance, and the bottom of the fixing groove is an arc surface and matches the fixing part, so that the friction between the fixing part and the bottom of the fixing groove can be increased or additional positioning can be provided. A limiting portion is provided on the inner side wall of the fixing groove for cooperating with the limiting groove on the fixing portion of the top belt 20 .In this embodiment, the limiting portion is preferably a limiting block, which can be a single long strip or a plurality of small blocks. The shape of the limiting block can be rectangular, trapezoidal, arc-shaped, etc., and its height and length match the size of the limiting groove on the fixing portion.

[0056] Further, in one embodiment of the present invention, the top strap 20 is made of high-strength, wear-resistant, breathable webbing or plastic material, such as nylon webbing, polypropylene webbing, TPU (thermoplastic polyurethane), etc. Figure 5 As shown, the top band 20 includes a bearing portion 21, four first connecting portions 22 connected to the outer periphery of the bearing portion 21 and symmetrically distributed in the circumference, two second connecting portions 23 connected to the middle of the bearing portion 21, a first fixing portion 24 connected to the end of the first connecting portion 22 and arranged obliquely, a first extending portion 25 connected to one side of each first connecting portion 22 by forking, two second extending portions 26 connected to both sides of each second connecting portion 23 by forking, and a second fixing portion 27 connected to the end of the second extending portion 26 by forking; wherein the bearing portion 21 is provided with a plurality of through holes distributed in the circumference, the first fixing portion 24 matches the first fixing groove 13, the second fixing portion 27 matches the second fixing groove 14, the end of the first extending portion 25 is provided with a first fixing hole connected and fixed to the cap hoop 30, wherein the end of the second connecting portion 23 is provided with a second fixing hole connected and fixed to the cap hoop 30. The bearing portion 21 is located at the center of the top band 20, is circular or elliptical, and is used to contact the top of the wearer's head. The bearing part 21 may be provided with a plurality of circumferentially distributed through holes to improve air permeability, achieve lightweight and disperse stress. The number of first connecting parts 22 is 4, and they are symmetrically distributed in the circumferential direction. The two ends of the first connecting part 22 are used to connect the bearing part 21 and the first fixing part 24, and the position close to the first fixing part 24 is also forked to connect the first extension part 25, wherein the first fixing part 24 is matched and connected with the first fixing groove 13 at the bottom of the cap shell 10. The first extension part 25 is forked to connect with one side of each first connecting part 22, and the end of the first extension part 25 is provided with a first fixing hole connected and fixed to the cap hoop 30, which is used to connect the cap hoop 30. The number of second connecting parts 23 is 2, and they are respectively connected to the middle of the left and right sides of the bearing part 21. The end of the second connecting part 23 away from the bearing part 21 is provided with a second fixing hole connected and fixed to the cap hoop 30. At the same time, two second extension portions 26 are bifurcated and connected on both sides of the second connection portion 23 , and the ends of the second extension portions 26 are connected to the inclined second fixing portions 27 , wherein the second fixing portions 27 are matched and connected with the second fixing grooves 14 at the bottom of the cap shell 10 .

[0057] Further, in one embodiment of the present invention, the safety helmet further comprises a sweat-absorbing belt 50 fixedly connected to the headband 30, wherein Figure 7As shown, the cap hoop 30 includes a ring band 31, and an adjustment band 32 and an adjustment buckle 33 respectively connected to both ends of the ring band 31; the ring band 31 is provided with a vent 311, an anti-collision column 312, a fixing column 313 for connecting and fixing the top band 20 and the chin band 40, and a fixing protrusion 314 for connecting and fixing the sweat-absorbing band 50 along its length direction. The vent 311 is used to increase the air permeability of the ring band 31 for ventilation and heat dissipation and stress dispersion. The anti-collision column 312 is used to disperse the impact force, avoid direct contact between the cap shell 10 and the wearer's head, reduce the impact of the cap shell 10 on the top of the wearer's head due to force deformation, and prevent head injuries. The fixing column 313 is used to cooperate and fix with the first fixing hole and the second fixing hole on the top band 20 of the safety helmet and the third fixing hole on the chin band 40. Specifically in this embodiment, the fixing column 313 adopts a T-shaped column, and the corresponding fixing holes on the top band 20 and the chin band 40 adopt T-shaped holes. The fixing protrusion 314 is used to pass through the fixing through hole of the sweat-absorbing belt 50 to fix the sweat-absorbing belt 50 .

[0058] Furthermore, a plurality of positioning holes 321 are provided on the adjusting belt 32 along its length direction; the adjusting buckle 33 includes a buckle body 331 connected to the ring belt 31, a positioning column 332 provided on the surface of the buckle body 331, and two ejection mechanisms 333 distributed on both sides of the buckle body 331; the buckle body 331 is provided with a channel running through both sides for the adjusting belt 32 to pass through, the positioning column 332 is provided with a guiding inclined surface for inserting the adjusting belt 32 on the entrance side of the channel, and the positioning column 332 is provided with a stop surface matching the positioning hole 321 and used for embedding the positioning hole 321 on the exit side of the channel, and the ejection mechanism 333 is used to synchronously lift the adjusting belt 32 when pressed to make the positioning hole 321 disengage from the positioning column 332.

[0059] In one embodiment of the present invention, the chin strap 40 is made of a soft, comfortable and durable webbing material, such as nylon webbing, polyester webbing, etc. The chin strap 40 includes a fixing strap and a buckle strap.
