Description

Technical Field

[0001] The invention belongs to the field of safety helmets and relates to a light warning safety helmet based on pressure induction. Background Art

[0002] At present, there is a situation where construction workers do not wear safety helmets properly at power operation sites, which will increase the risk of safety accidents, thus greatly increasing the work risks of on-site workers and increasing working hours. In addition, due to the uneven safety awareness of the workers, personal accidents are more likely to occur, such as accidental electric shock, head impact and other problems. These problems not only further increase the difficulty of on-site risk control, but also greatly reduce the safety level of employees. Nowadays, in view of the increasingly complex on-site environment of the power industry, the risk factors on site can only be controlled by increasing the training intensity and strict requirements for on-site workers. Therefore, there is an urgent need for a safety device that is simple to operate and can ensure the safe operation of on-site workers. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and to solve the problem of accidental safety accidents caused by improper wearing of safety helmets by on-site workers. A light warning safety helmet based on pressure sensing is proposed.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] The invention provides a light warning helmet based on pressure induction, comprising: a helmet body, a light indicator, and a pressure sensor, wherein the light indicator is installed at the front end of the helmet body; the pressure sensor is connected to the light indicator through a controller and is installed inside the helmet body.

[0006] Furthermore, it also includes a rechargeable battery, which is connected to the pressure sensor to supply power to the pressure sensor.

[0007] Furthermore, it also includes a fixed shell, which is used to protect the pressure sensor and the rechargeable battery inside the fixed shell.

[0008] Furthermore, a USB charging card slot is formed on the fixed shell of the helmet body and marked with a charging symbol.

[0009] Furthermore, buffer foam is installed between the fixed shell and the internal pressure sensor and rechargeable battery.

[0010] Furthermore, the fixed shell is made of high-strength engineering plastics.

[0011] Furthermore, the light indicator adopts a built-in constant current drive and a high-brightness LED lamp bead.

[0012] The advantages and positive effects of the present invention are:

[0013] 1. The present invention can use the pressure sensing patch of the built-in pressure sensor of the helmet to compare the contact pressure between the wearer's head and the helmet according to the preset force when the helmet is worn correctly. If it is worn correctly, the green light of the light indicator will light up, otherwise the red light will light up, so as to avoid the on-site workers wearing the helmet improperly, shorten the on-site working time, and reduce the occurrence rate of safety accidents.

[0014] 2. The present invention forms a USB charging card slot on the fixed shell of the helmet body and marks it with a charging symbol to improve the convenience of charging and facilitate users to charge in time.

[0015] 3. The present invention uses a fixed shell made of high-strength engineering plastic to cover the assembled pressure sensor, thereby maximizing the reliability during carrying and improving the overall durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0020] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “top”, “bottom”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] The present invention provides a light warning helmet based on pressure sensing, comprising: a helmet body 1, a light indicator 2, and a pressure sensor 3, wherein the light indicator 2 is installed at the front end of the helmet body 1; the pressure sensor 3 is connected to the light indicator through a controller and installed inside the helmet body 1. When the light warning helmet is worn, the pressure sensor transmits a signal of pressure change to the controller, and the controller compares the contact pressure between the wearer's head and the helmet at this time according to the preset force size when the helmet is worn correctly. If the helmet is worn correctly (that is, the contact pressure between the wearer's head and the helmet at this time is within the preset force range when the helmet is worn correctly), the controller controls the green light of the light indicator to light up, and if the helmet is worn incorrectly (that is, the contact pressure between the wearer's head and the helmet at this time is not within the preset force range when the helmet is worn correctly), the controller controls the red light of the light indicator to light up. The rechargeable battery is connected to the pressure sensor 3 to power the pressure sensor 3, and a fixed shell is provided, and the fixed shell is used to protect the pressure sensor 3 and the rechargeable battery inside the fixed shell. The present invention can use the pressure sensing patch of the built-in pressure sensor 3 of the helmet to compare the contact pressure between the head of the wearer and the helmet according to the preset force when the helmet is worn correctly. If the helmet is worn correctly, the green light of the light indicator 2 will light up, otherwise the red light will light up, so as to avoid the on-site workers wearing the helmet improperly, shorten the on-site working time, and reduce the occurrence rate of safety accidents.

[0022] Before the present invention is carried out on the job site, the produced light indicator 2 can be fixed at a fixed distance in advance in the studio to cooperate with the installation of the pressure sensor 3. Specifically, considering the ease of operation of the equipment by the workers, the multi-infrared indicator scanning solution is abandoned, and a miniaturized detection solution with a pressure sensor 3 connected to a rechargeable battery is adopted. The light warning safety helmet based on pressure sensing can ensure that the correct rate of workers wearing the safety helmet reaches 100%, while greatly reducing accidents caused by improper wearing of the safety helmet. The present invention, through the widely used light indicators for equipment indication in the industrial field and referring to the warning solution, determines a solution for installing a light indicator on the safety helmet to cooperate with pressure detection for conveniently checking whether the safety helmet is worn in compliance with regulations.

[0023] Based on this, before wearing the light warning helmet based on pressure sensing, the pressure sensing patch detection point of the pressure sensor 3 can be investigated first to determine the appropriate detection point, and then the mold of the fixed shell is produced by the manufacturer to connect the sensor patch of the pressure sensor 3 with the pressure sensor 3 and the light indicator 2. Among them, the fixed shell is made of high-strength engineering plastics. After the strength impact test, the fixed shell composed of this material can well protect the internal pressure sensor 3 and the rechargeable battery, and ensure the correct position of these two components. The present invention uses a fixed shell made of high-strength engineering plastics to cover the assembled pressure sensor 3, which maximizes the reliability when carrying and improves the overall durability. Corresponding to the USB charging port of the rechargeable battery, a USB charging card slot 4 is made on the fixed shell of the helmet body 1, and is marked with a charging symbol to improve the convenience of its charging and facilitate users to charge in time. In this way, even if the staff has weak work experience, they can quickly adapt to the use of the helmet and subsequent charging operations, while ensuring safe operation and avoiding safety accidents.

[0024] At the same time, considering the stability of the overall structure, a buffer foam is installed between the fixed shell and the internal pressure sensor 3 and the rechargeable battery, and the buffer foam is used for protection. The fixed shell is located at the side brim of the helmet body 1, which is convenient for multiple times to take and carry. The light warning helmet based on pressure sensing combines and fixes the individual components, and the volume is smaller than before, and the weight is also reduced.

[0025] After the light indicator 2, the pressure sensor 3 and the helmet body 1 are installed, the overall appearance of the pressure-sensing light warning helmet can be inspected, avoiding repeated operations such as disassembly and reassembly due to unstable connections found on site, reducing losses and risks, and ensuring that the reliability of the helmet reaches 100%.

[0026] In addition, considering the possibility of long-term work by on-site workers, the life of the light indicator 2 also needs to be considered. Therefore, the pressure-sensitive light warning helmet needs to ensure that the service life of the light indicator 2 will not be terminated prematurely during the product life cycle while ensuring 100% reliability. Based on this, the present invention can select a more durable built-in constant current driver and high-brightness LED lamp beads for the light indicator 2, so that on-site operators can check whether the helmets are worn in compliance with regulations at any time through the light indicator 2, thereby improving work efficiency and safety, and improving the acceptance of the new type of helmet by the staff.

[0027] The installation of the module device of the light warning helmet based on pressure sensing of the present invention, which includes the pressure sensor 3 and the rechargeable battery, specifically includes the following process:

[0028] S1. Prepare in the studio and select a suitable installation location that is convenient for operation and maintenance and does not affect normal wearing.

[0029] S2, installing the pressure sensor 3 into a fixed base preset in the fixed housing.

[0030] S3, install the rechargeable battery into the fixed base preset in the fixed housing, and connect it to the USB charging port of the rechargeable battery.

[0031] S4, install the wiring into the fixed housing, connect it to the appropriate position of the component pin of the pressure sensor 3, and fix each connection point.

[0032] S5, after the installation is completed, the light warning helmet based on pressure sensing is obtained.

[0033] S6. After assembly is completed, the pressure-sensing optical warning helmet should be inspected for structural stability.

[0034] S7, perform multiple pressure detection tests on the pressure-sensitive light warning helmet.

[0035] Before working at the power construction site, the present invention can first fix the produced pressure sensor 3 at a fixed distance in the studio in advance to complete the installation of the whole light-pressure sensing system, assemble and fix the produced pressure detection module including the pressure sensor 3 and the rechargeable battery in advance, and realize the easy-to-operate feature on site, so that after the pressure-sensing light warning safety helmet is transported to the site, it can be directly assembled on the operator to avoid tedious operations such as disassembly and assembly on site, thereby shortening the on-site working time.

[0036] The present invention adopts the light indicator 2 to indicate and cooperates with the pressure sensor 3 to detect the pressure, and proposes a convenient and safe light warning helmet based on pressure sensing, which can meet the needs of different working environments; at the same time, it is light and comfortable, light in weight, and has good air permeability, and is not burdensome to wear for a long time. It is also easy to maintain, and the detachable design facilitates cleaning and replacement of parts.

[0037] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept, which all belong to the protection scope of the present invention.
