Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an earphone airbag of a helmet. Background Art

[0002] Labor protection earphones are components that completely cover the ears along both sides of the head to form a seal for the left and right ears. The headband force (clamping / tightening force) refers to the force applied by the left and right earphones to the head after they completely cover the ears along both sides of the head. Too little force may result in inaudibility of the sound played by the earphones and hearing of external noises, while too much force may reduce the comfort of the head. The existing methods on the market can only customize the width of the helmet and add ordinary soundproofing ear pads to adjust the distance between the left and right earphones, so as to provide the head with a suitable headband force (clamping / tightening force). The problem is that this method is not convenient for adjusting the headband force (clamping / tightening force) later, and it can only be adjusted by replacing the soundproofing ear pads of other thicknesses. Utility Model Content

[0004] To achieve the above purpose, the utility model is implemented through the following technical scheme: an earphone airbag for a helmet, including a helmet, wherein expansion bodies are symmetrically bonded to the inner side of the helmet, and adjacent end faces of two expansion bodies are bonded to earphone bodies. By adjusting the air intake of the expansion bodies, the expansion amplitude of the expansion bodies is changed, thereby adjusting the distance between the two earphone bodies to adjust the headband force after the earphone bodies are worn.

[0005] Furthermore, the interior of the helmet is filled with noise reduction and heat preservation fillers, and the inner surface of the helmet is fixedly connected with an inner lining layer.

[0006] Furthermore, the noise reduction and heat preservation filler is a component made of foam material, and the inner lining layer is a component made of textile cloth material.

[0007] Furthermore, the expansion body is an air bag that can be inflated and deflated.

[0008] Furthermore, a Velcro fleece surface 1 is symmetrically fixedly connected to the inner wall of the helmet, a Velcro hook surface 1 is fixedly connected to one side of the expansion body, and the Velcro fleece surface 1 and the Velcro hook surface 1 are bonded and fixed.

[0009] Furthermore, a second Velcro fleece surface is fixedly connected to the other side of the expansion body, a second Velcro hook surface is fixedly connected to one side of the earphone body, and the second Velcro fleece surface is bonded and fixed to the second Velcro hook surface.

[0010] The utility model provides an earphone airbag for a helmet. Compared with the prior art, it has the following beneficial effects:

[0011] The earphone airbag suitable for the helmet has an expansion body with an airbag structure bonded between the helmet and the earphone main body. The volume of the expansion body can be adjusted, so that the distance between the two earphone main bodies can be adjusted, and the headband force of the earphone main body when being worn can also be adjusted, which is convenient, quick, simple and effective.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides a technical solution: an earphone airbag for a helmet, comprising a helmet 1, an expansion body 2 is symmetrically bonded to the inner side of the helmet 1, a Velcro fur surface 13 is symmetrically fixedly connected to the inner wall of the helmet 1, a Velcro hook surface 21 is fixedly connected to one side of the expansion body 2, the Velcro fur surface 13 and the Velcro hook surface 21 are bonded and fixed, the expansion body 2 is an inflatable and deflated airbag, the adjacent end surfaces of the two expansion bodies 2 are bonded to the earphone main body 3, the other side of the expansion body 2 is fixedly connected to the Velcro fur surface 22, the earphone A Velcro hook surface 2 31 is fixedly connected to one side of the main body 3, and the Velcro fur surface 22 is bonded and fixed to the Velcro hook surface 2 31. By adjusting the air intake of the expansion body 2, the expansion amplitude of the expansion body 2 is changed, thereby adjusting the distance between the two earphone main bodies 3 to adjust the headband force after the earphone main body 3 is worn. An air valve is provided on the surface of the expansion body 2. The structure and principle of the air valve adopt the existing technology and are not described in detail here. The specific effect of the air valve is to increase the volume of the expansion body 2 by repeatedly pressing the expansion body 2, and to reduce the volume of the expansion body 2 by long pressing the expansion body 2 to deflate.

[0019] In addition, the interior of the helmet 1 is filled with a noise-reducing and heat-insulating filler 11, and the inner surface of the helmet 1 is fixedly connected with an inner lining layer 12, wherein the noise-reducing and heat-insulating filler 11 is a component of foam material, and the inner lining layer 12 is a component of textile fabric material. The foam material can not only keep warm but also reduce noise, and the textile fabric can improve the wearing comfort of the helmet 1.

[0020] The installation method is: fit the Velcro hook surface 21 of the expansion body 2 with the Velcro fur surface 13 of the helmet 1, and fit the Velcro hook surface 2 31 of the earphone body 3 with the Velcro fur surface 22 of the expansion body 2. The disassembly method is opposite to the installation method.

[0021] When the distance between the two earphone main bodies 3 needs to be adjusted, the expansion body 2 is repeatedly pressed or long pressed to increase or decrease the volume of the expansion body 2 accordingly, so as to adjust the distance between the two earphone main bodies 3. After adjustment, the force of the two earphone main bodies 3 on the headband after wearing will change, thereby achieving the purpose of quick adjustment.
