Description

Technical Field

[0001] The utility model relates to the technical field of emergency management, in particular to a buffer protection type safety helmet. Background Art

[0002] A safety helmet is a hat that protects the head from injuries caused by falling and other specific factors. It is usually composed of a helmet shell, a hat lining, a chin strap and accessories. The helmet shell is the main component of the helmet, and generally adopts an elliptical or hemispherical thin shell structure. This structure will produce a certain pressure deformation under impact pressure, and due to the rigidity of the material, it absorbs and disperses the force, and the smooth surface and circular curve make it easy for the impact object to slide away, thereby reducing the impact time.

[0003] Therefore, in some dangerous occasions (such as construction sites), people entering are required to wear a helmet. However, even if the user wears the helmet correctly as required, when a relatively strong impact is applied to the helmet, the corresponding impact can still be transmitted to the wearer's head, causing the wearer to faint or be injured. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of the utility model is to provide a buffer protection type safety helmet to solve the problem that the protection ability of the existing safety helmet is limited and the wearer may still be injured when a strong impact is applied to the safety helmet.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The present application provides a buffering protective safety helmet, which includes a helmet shell and a chin strap arranged at the bottom end of the helmet shell, the helmet also includes a cross-shaped protective band, a headband made of a buffer material, and a buffer sheet, the cross-shaped protective band is arranged at the top end of the helmet shell inner cavity, the headband is fixedly installed at the bottom edge of the helmet shell inner cavity, the bottom end of the cross-shaped protective band is fixedly connected to the headband, and the buffer sheet is fixedly installed at the central bottom end of the cross-shaped protective band.

[0007] Furthermore, the safety helmet also includes an impact force detection device, which is fixedly installed on the outer surface of the safety helmet and is used to detect and sense the impact force applied to the safety helmet.

[0008] Furthermore, the impact force detection device includes an annular elastic mounting band, a controller and a plurality of acceleration sensors, wherein the plurality of acceleration sensors are fixedly mounted on the inner side surface of the annular elastic mounting band at intervals along the circumferential direction, the controller is fixedly mounted on the annular elastic mounting band, each of the acceleration sensors is communicatively connected to the controller, and the annular elastic mounting band is tightly mounted at the bottom end of the outer surface of the cap shell.

[0009] Furthermore, the annular elastic mounting band includes two opposite ends, one end of the annular elastic mounting band is provided with a slot, and the other end of the annular elastic mounting band is provided with a buckle that is tightly matched with the slot.

[0010] Furthermore, a locking buckle for adjusting the length of the annular elastic mounting belt is installed on the annular elastic mounting belt.

[0011] Furthermore, the controller includes a shell, an end cover and a controller chip. The controller chip is fixedly installed in a mounting groove provided on the shell, and the end cover is installed at the top of the mounting groove.

[0012] The beneficial effects of the utility model are:

[0013] 1. A disc-shaped buffer sheet is arranged at the center of the top of the inner cavity of the helmet. When the wearer uses the helmet, the buffer sheet is located in the center area above the wearer's head. In this way, when a strong external impact acts on the top area of ​​the helmet, the buffer sheet can slow down and reduce the external impact force acting on the wearer's head area, thereby protecting the top area of ​​the wearer's head. At the same time, the annular protective belt installed at the inner edge of the bottom of the inner cavity of the helmet is made of a buffer material. When the wearer wears the helmet, the outer edge of the wearer's head contacts the protective belt. When a strong external impact acts on the outer edge of the helmet, the protective belt is arranged between the wearer's head and the helmet. Therefore, the protective belt can slow down and reduce the external impact force acting on the side area of ​​the wearer, thereby protecting the area around the wearer's head.

[0014] 2. By configuring an impact force detection device for detecting and sensing the impact force applied to the safety helmet, an acceleration sensor can be used to further determine the size of the impact applied to the safety helmet and the position of the wearer's head where the impact is applied. By comprehensively analyzing and determining the size and position of the impact applied to the safety helmet and the type of accident, subsequent measures after the safety accident can be further reasonably and systematically implemented.

DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] See attached Figure 1 To Attachment Figure 3 As shown, this embodiment provides a cushioning protective helmet 100 , which includes a helmet shell 10 , a chin strap 30 , a cross-shaped protective strap 40 , a headband 60 made of a cushioning material, a cushioning sheet 50 and an impact force detection device 20 .

[0022] The helmet shell 10 is mainly made of lightweight metal such as aluminum, hard plastic or synthetic resin material. The cross-shaped protective band 40 is installed at the top of the inner cavity of the helmet shell 10. The headband 60 is bonded and fixed to the inner edge of the bottom end of the inner cavity of the helmet shell 10. The headband 60 is made of a cushioning material. Its function is to provide cushioning protection for the outer edges around the wearer's head, and the bottom end of the cross-shaped protective band is fixedly connected to the headband 60.

[0023] See attached Figure 2 As shown, the disc-shaped buffer sheet 50 is fixedly installed at the central bottom end of the cross-shaped protective belt 40. When the wearer uses a helmet with this structure, the central area of ​​the top of the wearer's head is basically located below the buffer sheet 50, so that the buffer sheet 50 can provide protection for the top area of ​​the wearer's head. That is, when the force generated by an external impact acts on the top area of ​​the helmet, the force applied to the top area of ​​the helmet will be transmitted to the buffer sheet 50 through the helmet shell 10. The buffer sheet 50 is used to reduce and mitigate the impact force of the external impact force on the top area of ​​the wearer's head, so as to protect the safety of the wearer's head.

[0024] Correspondingly, since the annular protective belt is installed at the inner edge of the bottom end of the inner cavity of the helmet, and the annular protective belt is made of a buffer material, when the wearer wears it, the outer edge of the wearer's head contacts the protective belt. When a strong external impact acts on the outer edge of the helmet, since the protective belt is set between the wearer's head and the helmet, the protective belt can slow down and reduce the force of the external impact on the wearer's side area, and play a role in protecting the area around the wearer's head. It can be seen that the setting of the buffer sheet 50 and the annular protective belt can effectively protect the wearer's head and improve the protective effect of the helmet on the user's head.

[0025] See attached Figure 1 and attached Figure 2 As shown, the chin strap 30 is fixedly mounted at the bottom end of the helmet shell 10 . When the wearer wears the helmet, the chin strap 30 can be used to fix the helmet on the wearer's head.

[0026] Combined with reference to Figure 1 and attached Figure 3 As shown, in order to determine the impact force received by the wearer's head so that corresponding coping measures can be taken in time, the safety helmet also includes an impact force detection device 20. The impact force detection device 20 is fixedly mounted on the outer surface of the safety helmet and is used to detect and sense the impact force applied to the safety helmet.

[0027] Specifically, the impact force detection device 20 includes an annular elastic mounting band 21, a controller 23 and a plurality of acceleration sensors 22. The plurality of acceleration sensors 22 are fixedly mounted on the inner side of the annular elastic mounting band 21 at intervals along the circumferential direction. The controller 23 is fixedly mounted on the annular elastic mounting band 21. Each acceleration sensor 22 is communicatively connected to the controller 23. The annular elastic mounting band 21 is tightly mounted on the bottom end of the outer surface of the cap shell 10.

[0028] Combined with reference to Figure 4 As shown, in order to prevent the controller 23 from being easily damaged, the controller 23 includes a shell 231 and an end cover 232 made of metal material, and a mounting groove is formed on the shell 231, and the mounting groove is used to install the controller chip 233. After the controller chip 233 is installed in the mounting groove, the end cover 232 is installed at the notch of the mounting groove, and cooperates with the shell 231 to protect the controller chip 233 and improve its impact resistance, so as to prevent the controller 23 from being easily deformed and damaged due to external impact during the use of the safety helmet.

[0029] Continue to refer to the attached Figure 4As shown, in order to flexibly adjust the use length of the annular elastic mounting band 21, a locking buckle for adjusting its length is installed on the annular elastic mounting band 21, and the locking buckle can adopt a common bag strap locking buckle adjustment structure on the market, such as a locking buckle structure for adjusting the length of the shoulder strap on a school bag. In addition, the annular elastic mounting band 21 includes two opposite ends, one end of the annular elastic mounting band 21 is provided with a slot, and the other end of the annular elastic mounting band 21 is provided with a buckle that is tightly matched with the slot. Through the arrangement of the buckle and the slot, the annular elastic mounting band 21 can be conveniently and quickly installed on the outer peripheral surface of the cap shell 10.

[0030] The acceleration sensor 22 is a semiconductor sensor for outputting the magnitude and direction of the acceleration applied to the object as the detection object. The type of the acceleration sensor 22 may be, for example, a piezoelectric resistance type and an electrostatic capacitance type. Based on the gravity acceleration, the movement of the corresponding object can be more accurately detected from the inclination angle and the acceleration in various directions of the object as the detection object. The impact force detection device 20 senses the impact applied to the helmet from the outside through the acceleration sensor 22, and uses the data input from the acceleration sensor 22 to send an accident occurrence signal to the outside so as to quickly obtain rescue.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
