In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0021] like Figure 1-Figure 2 As shown, the present invention provides a self-tightening chin strap safety helmet, comprising: a safety helmet body 1 and a self-tightening control mechanism.

[0022] like Figure 2 As shown, the self-tightening control mechanism includes a fixed housing 11, a control panel 13, a motor 14, a rechargeable battery 15 and a control button 16. The fixed housing 11 is mounted on the helmet body 1. The control panel 13, the motor 14 and the rechargeable battery 15 are mounted inside the fixed housing 11. The control panel 13 is connected to the motor 14, the rechargeable battery 15 and the control button 16 respectively. The output shaft of the motor 14 is connected to one end of the chin strap 2 through a shaft connector, and the other end of the chin strap 2 is fixed to the helmet body 1. The present invention connects the motor 14 through the control panel 13 of the self-tightening control mechanism, and connects the output shaft of the motor 14 to the chin strap 2. When wearing the helmet, the control button 16 is pressed to control the motor 14 to operate and perform the chin strap extension or contraction operation, so as to facilitate the adjustment of the chin strap 2 of the helmet to match the head of the operator, and complete the self-tightening of the chin strap, so as to avoid the operator on site from wearing the helmet improperly, shorten the on-site working time, and reduce the occurrence rate of safety accidents.

[0023] Before the present invention is carried out on the job site, the miniaturized motor 14 produced can be fixed in advance in the studio at a fixed distance to match the installation of the chin strap 2. Specifically, considering the ease of operation of the equipment by the workers, the scheme of the self-tightening chin strap of the mechanical structure is abandoned, and the electric chin strap tightening scheme of the motor 14 connected to the rechargeable battery 15 is adopted instead. The self-tightening chin strap safety helmet can ensure that the correct rate of the helmet wearing of the operator reaches 100%, and at the same time greatly reduce the accidents caused by the loose wearing of the helmet. Based on this, before wearing the self-tightening chin strap safety helmet, the motor size can be investigated first to determine the distance suitable for the motor 14, the chin strap 2, and the rechargeable battery 15, and then the mold of the fixed shell 11 is produced by the manufacturer for assembly. The present invention determines the mold of the fixed shell 11 of the motor 14 suitable for connecting the chin strap of the helmet by investigating the self-tightening technology of the automobile safety belt, so as to adapt to the fixing method of the automatic tightening of the chin strap.

[0024] Among them, the mold of the fixed shell 11 is made of high-strength engineering plastic. After the strength impact test, the fixed shell 11 made of this material can well protect the internal motor 14 and the rechargeable battery 15, and ensure the correct position of these two components, and correspond to the USB charging port of the rechargeable battery 15. A USB charging card slot 12 is made on the fixed shell 11 of the helmet body 1 and marked with a charging symbol to improve the convenience of charging the device and facilitate users to charge in time. In this way, even if the staff has little work experience, they can quickly adapt to the use of the new helmet and subsequent charging operations, while ensuring safe operation and avoiding safety accidents.

[0025] At the same time, considering the stability of the overall structure, a buffer foam is installed between the fixed shell 11 of the helmet body 1 and the internal motor 14 and rechargeable battery 15. The use of the buffer foam is convenient for protecting the motor 14 and the rechargeable battery 15, maximizing the reliability when carrying and improving the durability of the present invention. The fixed shell 11 is located at the side brim of the helmet body 1, which is convenient for multiple times to take and carry. The self-tightening chin strap helmet combines and fixes the individual components, and the volume is smaller than before, and the weight is also reduced.

[0026] After the self-tightening device is installed, the self-tightening chin strap helmet can be inspected for its overall appearance, which avoids repeated operations such as disassembly and reassembly due to unstable connections found on site, reduces losses and risks, and ensures that the helmet reliability rate reaches 100%.

[0027] In addition, considering the possibility of long-term work by on-site workers, the comfort of the chin strap 2 also needs to be considered. Therefore, the self-tightening chin strap helmet needs to ensure the comfort of the chin strap 2 material in long-term contact with the skin while ensuring 100% reliability. Based on this, the present invention can select a softer multi-strand woven composite material for the chin strap 2 material, taking into account both air permeability and comfort, so that on-site operators can wear it comfortably for a long time, improve work efficiency and safety, and improve the workers' acceptance of the new helmet.

[0028] The installation of the self-tightening control mechanism of the self-tightening chin strap helmet of the present invention specifically includes the following process:

[0029] S1. Prepare in the studio and select a suitable installation location that is convenient for operation and maintenance and does not affect normal wearing.

[0030] S2, installing the motor 14 into a preset fixed base of the fixed housing 11.

[0031] S3, the battery is installed into the fixed base preset in the fixed housing 11, and connected to the USB charging port of the rechargeable battery 15 at the same time.

[0032] S4, install the chin strap 2 into the fixed housing 11, connect it to the appropriate position of the motor 14, and fix each connection point.

[0033] S5, the installation is completed, and a self-tightening chin strap safety helmet is obtained.

[0034] S6. After assembly, the self-tightening chin strap helmet should be checked for structural stability.

[0035] S7, perform impact test on self-tightening chin strap helmets.

[0036] The present invention assembles and fixes the modules such as the motor 14 and the rechargeable battery 15 of the self-tightening chin strap safety helmet in advance, and realizes the characteristic of easy operation on site, so that after the self-tightening chin strap safety helmet is transported to the site, it can be directly assembled by the operating personnel to avoid tedious operations such as disassembly and assembly on site, thereby shortening the on-site working time.

[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.
