Description

Technical Field

[0001] This utility model belongs to the technical field of construction safety management equipment, and in particular relates to a safety helmet with a buffer structure for construction safety management. Background Technology

[0002] In outdoor operations, safety risks such as falling objects from heights, equipment collisions, and accidental bumps are always present. The head is a critical and vulnerable part of the human body, and its protection is directly related to the life safety of construction workers. Therefore, safety helmets have become an indispensable core protective equipment in construction scenarios. Their core requirement is to withstand impacts of multiple directions and different intensities through structural design, while ensuring wearing stability and comfort to meet the requirements of long-term operation.

[0003] Chinese patent application CN221653705U discloses a standard-wearing safety helmet, including a helmet body and a chin strap. The helmet body includes a shell and an inner liner installed within the shell. The helmet also includes an elastic element installed within the helmet body for support on the top of the head. This invention improves upon existing designs by making a simple improvement. When the chin strap is not fastened, the elastic element prevents the helmet from being fully put on the head. Therefore, when wearing this helmet, the user must fasten the chin strap securely to prevent the helmet from slipping off, thus improving its safety performance.

[0004] The aforementioned improvements to safety helmets focus on the mandatory constraints of wearing regulations. They mainly rely on traditional inner linings to absorb impact energy and lack a buffer structure designed for the gravity impacts commonly encountered in construction environments. This makes it difficult to achieve effective energy absorption, resulting in limited protection under high-intensity impacts and failing to balance safety and comfort.

[0005] To address these issues, we provide a safety helmet with a cushioning structure for construction safety management. Utility Model Content

[0006] The purpose of this invention is to provide a safety helmet with a buffer structure for construction safety management. By combining the helmet body and the buffer mechanism, it solves the problem that existing safety helmets do not have a buffer structure designed for common gravity impacts in the construction environment, resulting in limited protection under high-intensity impacts.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a safety helmet with a buffer structure for construction safety management. It includes a helmet body, a brim on one side of the helmet body, and a buffer mechanism at the top of the inner cavity of the helmet body. The buffer mechanism includes a ring sleeve disposed inside the helmet body. An elastic support member is fixedly connected to the top of the ring sleeve, and an air bladder is disposed at the bottom of the elastic support member. An air pump is fixedly connected to one side of the rear end of the helmet body, and one side of the air pump is connected to the air bladder via a hose. A pressure sensor is fixedly connected to the inner wall of the helmet body. The elastic support member adopts an arc-shaped plastic spring structure, evenly distributed along the circumference of the ring sleeve, which can provide stable support for the air bladder and has good elastic deformation capability. The air bladder is fixed to one side of the rear end of the helmet body via a hose. The air pump is connected, while the pressure sensor fixed to the inner wall of the cap monitors the pressure changes between the head and the cap in real time. The ring sleeve design ensures the integrated connection between the cushioning mechanism and the cap, preventing component displacement during impact and thus improving structural stability. When subjected to gravity impact, the elastic support quickly absorbs the initial impact energy through its own deformation, allowing sufficient reaction time for the airbag's cushioning action. The pressure sensor can detect changes in impact intensity and link the air pump to dynamically inflate and adjust the airbag. In the event of a minor collision, the airbag remains soft to ensure wearing comfort. In the event of a high-intensity gravity impact, the air pump quickly inflates the airbag, rapidly filling it to form a rigid protective layer, effectively dissipating impact energy and preventing the head from directly bearing concentrated impact force.

[0009] The present invention is further configured such that an inner lining assembly is provided in the inner cavity of the cap body and below the airbag. The inner lining assembly includes a honeycomb buffer layer, and a breathable fabric layer is fixedly connected to the inner wall of the honeycomb buffer layer. The honeycomb buffer layer bears the residual impact energy after the initial buffering by the airbag, avoids the concentration of local impact force, and further improves the comprehensiveness of protection. The breathable fabric layer is in direct contact with the head, which not only enhances the softness and fit of wearing, but also reduces the feeling of pressure, so that protection and comfort are taken into account, and it is suitable for the needs of wearing for a long time during construction.

[0010] The present invention is further provided that a reinforcing rib is fixedly connected to the top of the hat body. The reinforcing rib and the hat body are integrally formed. The integrally formed reinforcing rib structure ensures the connection between the reinforcing rib and the hat body and improves the structural strength and impact resistance of the top of the hat body.

[0011] The present invention is further configured such that connecting straps are fixedly connected to both sides of the bottom of the brim, and an adjustment strap is provided at the bottom of the connecting strap. A buckle is provided on one side of the adjustment strap. The connecting strap provides stable support for the adjustment strap. The length of the adjustment strap can be freely adjusted according to the head circumference of the construction worker. The buckle can quickly realize the fixing and removal of the safety helmet, ensuring that it is worn firmly and does not loosen, and avoiding the failure of protection due to the displacement of the safety helmet during the operation.

[0012] The present invention is further configured such that the honeycomb buffer layer is made of EVA foam material, and the breathable fabric layer is made of cotton-polyester blend breathable fabric. The honeycomb buffer layer is made of EVA foam material, which can efficiently absorb impact energy and is not easily deformed after long-term use, thus ensuring the stability of the buffering performance. The breathable fabric layer is made of cotton-polyester blend material, which combines the softness and skin-friendliness of cotton with the wear-resistant and breathable properties of polyester, quickly absorbing sweat from the head and reducing stuffiness.

[0013] The present invention is further configured such that a connecting block is fixedly connected to the surface of the annular sleeve, and the top of the connecting block is fixedly connected to the elastic support. The annular sleeve is fixed to the elastic support through the connecting block, and the connecting block provides a stable mounting point for the elastic support, ensuring the stability of the connection between the elastic support and the annular sleeve.

[0014] The present invention is further provided that a ventilation hole is provided on one side of the hat body, and the ventilation holes are equally spaced to form a uniform ventilation channel, so as to realize the circulation of air inside and outside the hat body, quickly expel the heat and moisture inside the hat body, and effectively improve the stuffiness and discomfort of wearing for a long time.

[0015] The present invention is further configured such that the elastic support is an arc-shaped plastic spring sheet, and there are four of them. The elastic support is evenly distributed along the top circumference of the annular sleeve. The arc-shaped structure gives the spring sheet excellent elastic deformation capability, and it can quickly rebound and absorb energy when impacted, thus reserving sufficient reaction time for the dynamic buffering of the airbag.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model combines support and elasticity through four evenly distributed elastic support members, which can quickly deform to absorb the initial gravitational impact energy, leaving reaction time for the airbag buffer. The pressure sensor and air pump are linked to sense the impact intensity in real time and adjust the airbag inflation state. In the event of a high-intensity impact, it quickly inflates to form a rigid protective barrier, effectively dissipating the gravitational impact energy. Compared with the traditional structure that only relies on the inner lining to absorb energy, the protective effect is greatly improved. At the same time, it remains soft and fits well in the event of a low-intensity collision, taking into account both safety protection and wearing comfort in construction scenarios.

[0018] 2. This utility model uses EVA foam material for the honeycomb buffer layer. Its honeycomb structure can efficiently absorb the residual impact energy that has been initially dissipated by the buffer mechanism, avoiding localized stress concentration and solving the problem of limited energy absorption of traditional linings. The cotton-polyester blend breathable fabric layer of the inner wall conforms to the contour of the head, reducing the pressure of wearing it for a long time. At the same time, it has good sweat absorption and breathability. Combined with the ventilation holes of the hat body, it forms air circulation and effectively improves stuffiness and discomfort.

Detailed Implementation

[0027] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figure 1-6This utility model is a safety helmet with a buffer structure for construction safety management. It includes a helmet body 1, with a reinforcing rib 5 fixedly connected to the top of the helmet body 1. The reinforcing rib 5 and the helmet body 1 are integrally formed. Ventilation holes 10 are provided on one side of the helmet body 1, and the ventilation holes 10 are equidistantly spaced. A brim 2 is provided on one side of the helmet body 1, and connecting straps 6 are fixedly connected to both sides of the bottom of the brim 2. An adjusting strap 7 is provided at the bottom of the connecting strap 6, and a buckle 8 is provided on one side of the adjusting strap 7. A buffer mechanism 3 is provided at the top of the inner cavity of the helmet body 1. The buffer mechanism 3 includes a ring sleeve 31. A connecting block 9 is fixedly connected to the surface of 31. The top of the connecting block 9 is fixedly connected to the elastic support 32. The annular sleeve 31 is located inside the cap body 1. The top of the annular sleeve 31 is fixedly connected to the elastic support 32. The elastic support 32 is an arc-shaped plastic spring, and there are four of them. The elastic support 32 is evenly distributed along the top circumference of the annular sleeve 31. An air bladder 33 is provided at the bottom of the elastic support 32. An air pump 34 is fixedly connected to one side of the rear end of the cap body 1. One side of the air pump 34 is connected to the air bladder 33 through a hose. A pressure sensor 35 is fixedly connected to the inner wall of the cap body 1.

[0029] Specifically: The elastic support 32 adopts an arc-shaped plastic spring structure, evenly distributed along the circumference of the annular sleeve 31, which can provide stable support for the airbag 33 and has good elastic deformation capability. The airbag 33 is connected to the air pump 34 fixed on one side of the rear end of the cap body 1 through a hose, while the pressure sensor 35 fixed on the inner wall of the cap body 1 monitors the pressure change between the head and the cap body 1 in real time. The setting of the annular sleeve 31 ensures the integrated connection between the buffer mechanism 3 and the cap body 1, avoiding the displacement of components during impact and thus preventing the protection from failing, improving the structural stability. When subjected to gravity impact, the elastic support 32 quickly absorbs the initial impact energy through its own deformation, leaving sufficient reaction time for the buffer action of the airbag 33. The pressure sensor 35 can sense the change in impact intensity and link the air pump 34 to dynamically inflate the airbag 33. In the case of slight collision, the airbag 33 remains soft to ensure wearing comfort. In the case of high-intensity gravity impact, the air pump 34 quickly inflates the airbag 33, making it quickly inflate to form a rigid protective layer, effectively dissipating the impact energy and preventing the head from directly bearing concentrated impact force.

[0030] The inner cavity of the cap body 1 and below the air bladder 33 is provided with an inner lining component 4. The inner lining component 4 includes a honeycomb buffer layer 41. A breathable fabric layer 42 is fixedly connected to the inner wall of the honeycomb buffer layer 41. The honeycomb buffer layer 41 is made of EVA foam material, and the breathable fabric layer 42 is made of cotton-polyester blended breathable fabric.

[0031] Specifically: the honeycomb buffer layer 41 absorbs the residual impact energy after the initial cushioning by the airbag 33, avoiding localized impact concentration and further enhancing the overall protection. The breathable fabric layer 42 is in direct contact with the head, which not only enhances the softness and fit of the garment, but also reduces the feeling of pressure, balancing protection and comfort, and is suitable for long-term wear during construction. The honeycomb buffer layer 41 is made of EVA foam material, which efficiently absorbs impact energy and is not easily deformed after long-term use, ensuring the stability of the cushioning performance. The breathable fabric layer 42 is made of cotton-polyester blend material, which combines the softness and skin-friendliness of cotton with the wear-resistant and breathable properties of polyester, quickly absorbing sweat from the head and reducing stuffiness.

[0032] The working principle of this utility model is as follows: When construction workers wear the helmet, they can adjust the length of the strap 7 to fit their head circumference and use the buckle 8 to quickly fix the helmet. When encountering heavy impacts such as falling objects from a height, the helmet body 1 first bears the external impact force. The reinforcing rib 5 enhances the structural stability of the helmet body 1 and prevents the helmet body 1 from deforming. The pressure sensor 35 on the inner wall of the helmet body 1 senses the pressure change generated by the impact in real time and quickly sends a signal to the air pump 34. The pressure sensor 35 adopts a MEMS piezoresistive sensor, and the air pump 34 adopts a Thomas micro piston pump.

[0033] When the four elastic support members 32 are impacted, they quickly undergo elastic deformation to absorb the initial impact energy, providing time for the airbag 33 to buffer and react. After receiving the signal from the pressure sensor 35, the air pump 34 quickly inflates the airbag 33 through the hose, effectively dissipating the remaining impact force and avoiding concentrated pressure on the head. In the event of a minor collision, it remains soft, ensuring comfort. The EVA foam honeycomb buffer layer 41 under the airbag 33 disperses local impact force through its honeycomb structure, further enhancing the overall protection.
