Description

Technical Field

[0001] The utility model relates to a helmet, in particular to an earphone connecting structure for a helmet. Background Art

[0002] At present, in some protection scenarios, it is necessary to wear a helmet to ensure the safety of the operator. However, wearing a helmet, especially a low-cut or half-cut helmet, will have a great impact on the communication between the operator and the outside world. Especially in some environments where noise reduction is required, the interference between the volume of the headset and the helmet, and the inconvenience of disassembling and assembling the headset when not working often bring great inconvenience to the user. The current solution is to wear a thin headset hanging on the top of the head, and then wear a helmet. The head-mounted integrated headset body and the helmet are two separate components. The above layout scheme can certainly realize the communication function of the helmet, but it has the common problem of rigid layout and difficult to replace and expand. When the user needs to take off the headset, he needs to take off the heavy helmet first. At the same time, the headset cannot be replaced with other components in a modular way. In this way, the headset not only occupies the position of the modular replacement parts, but also greatly increases the difficulty and inconvenience of the user taking off the headset. Therefore, the existing headset helmet connection structure needs to be improved. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a helmet-used earphone connection structure, which can effectively improve the disassembly and assembly and interchangeability of the helmet-used earphone.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The invention discloses an earphone connection structure for a helmet, which is symmetrically installed on both sides of the helmet, and comprises an earphone body, a telescopic member, elastic steel, a guide rail and a guide rail fixing member. The guide rail is installed on the helmet and is consistent with the curved surface of the helmet at the installation position. The guide rail fixing member is detachably installed on the guide rail and can be adjusted in the front-rear direction along the guide rail. The elastic steel is connected to the guide rail fixing member. The telescopic member is partially sleeved on the elastic steel, and one end of the telescopic member is detachably connected to the earphone body. The upper and lower positions of the earphones are adjusted by sliding the telescopic member up and down on the elastic steel. The front-rear position of the earphones is adjusted by adjusting the front-rear position of the guide rail fixing member on the guide rail.

[0006] Preferably, the guide rail is provided with a plurality of pickup slots, and the guide rail fixing piece is provided with an elastic card block, which is stuck in the pickup slots.

[0007] Preferably, the guide rail and the guide rail fixing are connected via a spring button.

[0008] Preferably, a control panel is provided on the earphone body.

[0009] Preferably, the telescopic member and the elastic steel are interference fit, and a limiting component is provided between the telescopic member and the elastic steel.

[0010] Preferably, the limiting component adopts a structure of a groove and an elastic protrusion.

[0011] Preferably, the helmet rail is fixed to the helmet by screws.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) Since the earphone body, telescopic part, elastic steel, and guide rail fixing part can be separated into discrete parts and fastened to the helmet guide rail, the layout is very flexible and convenient. When other devices need to be installed on the guide rail, there is no need to change the rest of the helmet layout. The entire earphone body, telescopic part, elastic steel, and guide rail fixing part module can be removed by using a spring button, which has good scalability.

[0014] (2) At the same time, the earphone body can be stored outside the helmet body when not in use, which can meet the needs of users who do not need to wear earphones but need to receive external sounds, eliminating the shortcomings of existing helmet earphones such as inconvenience in removing and inability to meet replacement requirements;

[0015] (3) The guide rail can also fix other common components such as flashlights to ensure interchangeability;

[0016] (4) The utility model has a simple structure, is easy to use, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 1 to Figure 3 A headset connection structure for a helmet includes an headset body 1, a telescopic part 2, an elastic steel 3, a guide rail 4 and a guide rail fixing part 5. The headset body 1, the telescopic part 2, the elastic steel 3, the guide rail 4 and the guide rail fixing part 5 can be disassembled into separate parts and can be fastened to the helmet rail.

[0022] The helmet rails 4 are fixed to both sides of the helmet by screws, and their curved surfaces are consistent with the curved surfaces of the helmet for contour positioning. The rail fixing member 5 can move forward and backward along the helmet rails 4, and the rails 4 have a standard pickup slot. When fixed, the rail fixing member 5 can be stuck in the slot and can be removed and installed by a button.

[0023] The guide rail fixing member 5 and the elastic steel 3 are fixedly connected. The elastic steel has elastic force, which can clamp the earphone on both sides of the auricle, and at the same time, an outward force can be applied to the elastic steel to pull it away from the auricle.

[0024] The elastic steel 3 is covered with a telescopic part 2 with an interference fit. The telescopic part itself has no telescopic function and is made of engineering plastic. It can slide up and down on the elastic steel 3. There is a limit part designed inside it so that it will not slide off. One end of the telescopic part 2 is connected to the earphone body 1. According to the different heights of the head and neck, the upper and lower positions of the earphone body 1 can be adjusted by sliding to achieve good noise reduction adaptation.

[0025] The limiting component may adopt a known structure, such as a structure of a groove and an elastic protrusion.

[0026] In this embodiment, preferably, the earphone body 1 is provided with a control panel 101, through which the user can realize blind operation when wearing the earphone, and can control the volume, channel, etc. without taking off the earphone. Preferably, the earphone body 1 can be pulled away from the auricle through the telescopic member 2 without taking it off, and then pulled outward through the elastic steel 3, and then stored on the outer helmet body, so that the user's need of not wearing the earphone can be met without taking off the earphone.

[0027] The guide rail fixing part 5 is connected to the guide rail 4 via a spring button 501. By pressing the spring button 501, the guide rail fixing part can be removed from the guide rail, which is convenient for disassembly and assembly. The guide rail itself can fix other common components such as flashlights to meet interchangeability.

[0028] With the above structure, the earphones and their connectors can be fixed on the universal guide rail as a module. When the earphones are not in use, the entire module can be removed to achieve lightweight helmet, or other accessories with universal guide rail interfaces such as flashlights can be replaced. When the earphones are not in use, the helmet with the above structure does not need to be removed from the entire helmet or the layout of the helmet body, and accessories can be directly replaced. At the same time, the earphones can be stored on the outside of the helmet, which is very convenient to use.

[0029] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0030] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
