Description

Technical Field

[0001] The invention relates to the field of fire safety, in particular to a safety helmet with a collision buffer structure. Background Art

[0002] With the continuous development of society, people's safety awareness is constantly improving. Usually when working in a factory, we need to wear a safety helmet. A safety helmet is a protective device to prevent impact objects from injuring the head. It is mainly composed of a helmet shell, a lower cheek strap and a protective structure. When the worker's head is impacted by a falling object, the impact force first acts on the helmet shell, and then the elastic deformation, plastic deformation and structural changes within the allowable range of the buffer structure of each part of the safety helmet are used to absorb most of the impact force, so that the final impact force acting on the person's head is reduced, thereby protecting the operator's head. The specific helmet shell is elliptical or hemispherical with a smooth surface, so that when an object falls on the helmet shell, it will immediately slide down to prevent secondary crushing injuries, and the force at the impact point of the helmet shell is transmitted to the surrounding area, turning the force point into a force surface, thereby avoiding the stress concentration of the impact force at a certain point on the helmet shell, causing excessive pressure, causing damage to the helmet shell, and then causing damage to the head.

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings.

[0033] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0034] Reference Figure 1 The present embodiment provides a safety helmet with a collision buffer structure, including a brim 100 and a cap body 200 connected to each other; a reinforcing component 600 is arranged on the brim 100 to enhance the compressive resistance of the brim 100; in this embodiment, when the cap body 200 encounters a collision, it can transfer force to the brim 100, and the reinforcing component 600 on the brim 100 can form an effective support for the stressed brim 100 to avoid damage to the brim 100.

[0035] A shock-absorbing component 300 is arranged on the cap body 200 for absorbing the vibration of the cap body 200, and a buffer component 400 is arranged inside the cap body 200 for constructing a buffer zone between the wearer and the cap body 200; a force-bearing component 500 is also arranged between the cap body 200 and the brim 100, and when the cap body 200 is subjected to pressure, the force-bearing component 500 can disperse the pressure and transfer it to the brim 100. By setting the buffer zone, the problem of the wearer's head being squeezed and damaged by the brim 100 due to the deformation of the cap body 200 caused by collision can be effectively avoided. By setting the force-bearing component 500, when a part of the cap body 200 is subjected to pressure, it can be transferred to the brim 100 more evenly through the force-bearing component 500, thereby avoiding the problem of serious damage to a part of the brim 100 due to force.

[0036] The brim 100 includes a bottom brim 102 and a surround 103, and the brim 100 is connected to the cap body 200 through the surround 103. The reinforcing component 600 includes a reinforcing block 601 and a triangular support frame 602 arranged between the surround 103 and the bottom brim 102. No matter the reinforcing block 601 or the triangular support frame 602, one end of both is in contact with the bottom brim 102 and the other end is in contact with the surround 103. Because the cap body 200 is directly installed on the surround 103, when the cap body 200 is subjected to force, the surround 103 will also be subjected to pressure. By supporting the surround 103 on the radial side wall of the surround 103 through the reinforcing block 601 and the triangular support frame 602, the strength of the surround 103 can be effectively enhanced to avoid the problem of damage to the surround 103.

[0037] The force-bearing component 500 includes a head seat 501 disposed on the cap body 200; at least two force-bearing bones 502, one end of which is connected to the head seat 501 and the other end is connected to the brim 100. When the cap body 200 is under pressure, the pressure can be dispersed and transmitted to the brim 100 through the force-bearing bones 502. In this embodiment, the number of force-bearing bones 502 is 8. Connection holes are provided at both ends of the 8 force-bearing bones 502. At the edge position of the head seat 501, threaded holes are provided at the corresponding positions of the 8 force-bearing bones 502. Thus, the force-bearing bones 502 can be stably installed on the head seat 501 through bolts. In this embodiment, the 8 force-bearing bones 502 are arranged in a circle. When the cap body 200 is subjected to a collision pressure, the force can be transmitted to the head seat 501, and through the head seat 501, the force can be transmitted to the 8 force-bearing bones 502, and the 8 force-bearing bones 502 evenly transmit the force to the brim 100.

[0038] In this embodiment, in order to reduce the direct extrusion of the head seat 501 on the wearer's skull, first of all, the head seat 501 has an inner core made of a hard metal material or a polycarbonate material, and a flexible material such as sponge or silicone material is wrapped on the side of the inner core away from the cap body 200 and facing the wearer's head.

[0039] Secondly, by installing the head seat 501 at the center position of the cap body 200, corresponding to the center position of the human head, and increasing the radian of this position of the cap body 200, there is a gap between the head seat 501 and the human head when the person wears it, so as to avoid the head seat 501 directly transmitting the force to the human head when the cap body 200 is under force.

[0040] A protective ring 101 is provided on the brim 100. One end of the force-bearing bone 502 is connected to the protective ring 101. The protective ring 101 is the main component of the bottom brim 102 and is similar to an annular structure. The wearer's head can enter the inside of the cap body 200 through the protective ring 101. In this embodiment, the protective ring 101 has an extended bottom side 105 that slopes outward to a certain extent. The extended bottom side 105 can be an arc surface or a flat surface. Mainly when the person wears it, the extended bottom side 105 can extend around the person's head, avoiding the bottom side of the protective ring 101 from directly fitting completely with the human head.

[0041] The force-bearing bone 502 is connected to the protective ring 101, and a locking groove 104 is provided on the protective ring 101; one end of the force-bearing bone 502 can be inserted into the inside of the locking groove 104. Specifically, the bottom end of the force-bearing bone 502 can be inserted into the inside of the locking groove 104. A hole is provided inside the locking groove 104, which can be a threaded hole or a riveting hole, for connecting the bottom end of the force-bearing bone 502 inside the locking groove 104. Therefore, when the cap body 200 is under force, the pressure can be transmitted to the protective ring 101 through the force-bearing bone 502.

[0042] As an alternative embodiment, the locking groove 104 is provided on the extended bottom side 105. In this way, when the force-bearing bone 502 transmits pressure to the protective ring 101, the direction of the pressure is not completely downward. If the pressure is completely downward, the entire pressure still needs to be borne by the human head. Connecting the lower end of the force-bearing bone 502 to the extended bottom side 105 enables the force application direction of the force-bearing bone 502 to the protective ring 101 to generate a horizontal component force, which does not need to be borne by the human head and is instead applied to the protective ring 101 itself.

[0043] The shock-absorbing component 300 is a plurality of pressure-resistant plates 301 provided on the cap body 200. A pressure-dividing window 201 is provided on the cap body 200, and a connecting surrounding plate 202 is arranged inside the pressure-dividing window 201; a clamping plate 302 is provided on the pressure-resistant plate 301, and the pressure-resistant plate 301 can be assembled inside the pressure-dividing window 201 by clamping the clamping plate 302 to the connecting surrounding plate 202.

[0044] Among them, the pressure-resistant plates 301 on the cap body 200 play a role in sharing pressure. When the cap body 200 is stressed, especially when subjected to downward pressure, it will deform itself. At this time, the deformation of the cap body 200 will cause the pressure-dividing window 201 on the cap body 200 to deform, so that the inner wall of the pressure-dividing window 201 squeezes the pressure-resistant plate 301, causing the pressure-resistant plate 301 to deform. The deformation of the pressure-resistant plate 301 will generate an elastic force to offset part of the pressure received by the cap body 200.

[0045] In order to improve the pressure resistance and compressive elastic force of the pressure-resistant plate 301, the pressure-resistant plate 301 is made of honeycomb material. Through the honeycomb design, the pressure-bearing capacity of the pressure-resistant plate 301 against pressure can be effectively improved, and at the same time, it can provide good support for the deformed cap body 200.

[0046] The connecting surrounding plate 202 preferably has the same shape as the pressure-dividing window 201, except that the size of the connecting surrounding plate 202 needs to be smaller than that of the pressure-dividing window 201. The connecting surrounding plate 202 is installed on the inner wall of the pressure-dividing window 201, and the clamping plate 302 can be clamped inside the connecting surrounding plate 202. To prevent the clamping plate 302 from separating from the inside of the connecting surrounding plate 202, the clamping plate 302 and the connecting surrounding plate 202 are preferably further reinforced by adhesive bonding.

[0047] The buffer component 400 includes a buffer inner pad 401. The buffer inner pad 401 is arranged inside the cap body 200. The buffer inner pad 401 has a stress-bearing surface 402 that fits the inner wall of the cap body 200 and a support end 403 that is connected to the brim 100; when the cap body 200 is deformed by force, it can transmit the force to the buffer inner pad 401.

[0048] In this embodiment, an opening 406 also needs to be formed at the top of the buffer inner pad 401. The head seat 501 needs to be connected to the inner wall of the cap body 200 through the opening 406. More preferably, the size of the opening 406 is larger than that of the head seat 501, so that the head seat 501 can be completely above the opening 406. In this way, the contact between the human head and the head seat 501 can be further avoided, and instead, the contact between the buffer inner pad 401 and the human head is achieved.

[0049] As an alternative embodiment, protruding contact protrusions 407 can also be provided on the inner wall of the buffer inner pad 401. Both the buffer inner pad 401 and the contact protrusions 407 need to be made of flexible materials, such as polystyrene foam or silica gel. By providing the contact protrusions 407, the distance between the human head and the head seat 501 can be further increased, and the contact between the human head and the head seat 501 can be effectively avoided.

[0050] In order to reduce the fitting of the stress-bearing bone 502 and the human head, an inner through groove 404 also needs to be formed on the inner wall of the buffer inner pad 401. One end of the inner through groove 404 penetrates through the inner wall of the buffer to form an insertion port 405, and the other end of the inner through groove 404 penetrates through the support end 403 of the buffer inner pad 401. In this way, one end of the stress-bearing bone 502 can enter the inner through groove 404 through the insertion port 405 and extend out from the support end 403 of the inner pad through the inner through groove 404. This serves two purposes:

[0051] First, it can enable the stress-bearing bone 502 to avoid the area where it fits with the human head. When wearing a safety helmet, there will be an annular area on the human head that fits with the inner wall of the safety helmet. In this embodiment, it is the bottom area of the buffer inner pad 401. Through the inner through groove 404, the stress-bearing bone 502 can be hidden inside the buffer and pass through this area to be connected to the protection ring 101, which can prevent the stress-bearing bone 502 from fitting too closely with the human head and transmitting too much pressure to the human head.

[0052] Second, since the stress-bearing bone 502 passes through the buffer inner pad 401, the buffer inner pad 401 is also supported to a certain extent. When the cap body 200 is deformed under force, the pressure can be better transmitted to the stress-bearing bone 502, thereby sharing the pressure on the buffer inner pad 401 and preventing all the pressure received by the buffer inner pad 401 from being transmitted to the human head.

[0053] Finally, it should be noted that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
