Description

Technical Field

[0001] This utility model relates to the field of helmet technology, specifically to a detachable helmet headset, which is particularly suitable for protective equipment such as cycling helmets and sports helmets that require integrated audio functions, enabling quick assembly and disassembly of the headset and the helmet and a stable connection. Background Technology

[0002] Traditional helmet headsets typically use a fixed mounting method, such as glue or screws, which leads to the following problems:

[0003] Inconvenient maintenance: When the headphones are damaged, the entire helmet needs to be replaced or complex disassembly is required, increasing the cost of use;

[0004] Insufficient stability: The simple plug-in structure is easily affected by vibration or external force, causing the earphones to fall off;

[0005] Limited functionality: The earphones cannot be removed and used separately, which limits their adaptability to different scenarios. Utility Model Content

[0006] This invention provides a detachable helmet headset, enabling quick assembly and disassembly of the headset and helmet, a secure connection, and support for individual replacement of the headset module, thereby improving ease of use and maintenance efficiency.

[0007] Helmet body structure:

[0008] The helmet body has headphone jacks on both sides, and the jacks are equipped with guide holes, arc-shaped guide grooves, and limiting holes, which are interconnected to form an installation path. The cross-section of the guide hole matches the guide block to ensure sliding accuracy.

[0009] Headphone mounting structure:

[0010] The headphones are connected to the helmet via a mounting base. A guide block is fixed on the mounting base. After the guide block is inserted into the guide hole, it slides along the arc-shaped guide groove. The guide block has a limiting slide cavity, and a limiting slide plate, a spring, and a limiting head are installed inside the cavity.

[0011] The end of the limiting head is hemispherical, and the diameter of the limiting hole matches the maximum diameter of the limiting head.

[0012] One end of the spring is fixedly connected to the inner wall of the limiting slide cavity, and the other end is fixedly connected to the limiting slide plate. When the spring is in its natural state, the end of the limiting head extends out of the opening of the limiting slide cavity. When the guide block slides to the limiting hole, the limiting head can automatically lock into the hole under the elastic force of the spring to form a mechanical lock and prevent the earphone from falling off accidentally.

[0013] The mounting base and earphones are detachably connected via a snap-and-slot structure, making it easy to replace the earphone module separately. The inner wall of the mounting base's slot is equipped with anti-slip textures or a rubber pad to enhance wearing comfort and stability.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Quick assembly and disassembly: The headphone can be installed and disassembled without tools by sliding the guide block along the arc-shaped guide groove and automatically engaging with the limiting head, reducing the operation time to within 5 seconds;

[0016] Dual stability: The precise fit between the guide block and the guide hole provides radial support, while the mechanical locking of the limiting head and the limiting hole prevents axial displacement and can withstand axial tensile forces of over 50N. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-5 As shown;

[0028] This embodiment provides a detachable helmet-mounted headset, including a helmet body 1. Headphone jacks 2 are located on both sides of the helmet body 1. Guide holes 3, arc-shaped guide grooves 4, and limiting holes 5 are formed on the helmet body 1 at the headphone jacks 2. The guide holes 3, arc-shaped guide grooves 4, and limiting holes 5 are interconnected to form a complete installation guide path. An earphone 6 is inserted into the headphone jack 2. A mounting base 7 is provided on the earphone 6, and a guide block 8 is fixed on the mounting base 7. The cross-sectional shape of the guide block 8 matches the cross-sectional shape of the guide hole 3, ensuring that the guide block 8 can be accurately inserted into the guide hole 3 and slide smoothly along the arc-shaped guide groove 4. A buckle groove 9 is provided on the mounting base 7. The inner wall of the buckle groove 9 is provided with anti-slip textures or a rubber pad layer to enhance the fit and stability during wear.

[0029] A limiting cavity 81 is formed on the guide block 8. A limiting disk 82 is set inside the limiting cavity 81. A limiting head 83 is fixed to one end of the limiting disk 82. The end of the limiting head 83 is hemispherical. The diameter of the limiting hole 5 matches the maximum diameter of the limiting head 83. When the limiting head 83 is inserted into the limiting hole 5, a reliable limiting fit can be formed to prevent the earphone 6 from accidentally falling off. A spring 84 is set inside the limiting cavity 81. One end of the spring 84 is fixedly connected to the inner wall of the limiting cavity 81, and the other end is fixedly connected to the limiting disk 82. When the spring 84 is in its natural state, the end of the limiting head 83 extends out of the opening end of the limiting cavity 81, so as to ensure that when the guide block 8 slides to the position of the limiting hole 5, the limiting head 83 can automatically insert into the limiting hole 5 under the elastic force of the spring 84.

[0030] The mounting base 7 and the earphone 6 are fixedly connected by a detachable connection structure, which includes a buckle on the mounting base 7 and a slot on the earphone 6, making it easy to replace the earphone module separately.

[0032] Align the mounting base 7 of the earphone 6 with the earphone jack 2 of the helmet body 1, and insert the guide block 8 into the guide hole 3.

[0033] Rotate the earphone 6 clockwise, and the guide block 8 slides along the arc-shaped guide groove 4. At this time, the spring 84 is compressed and contracts, and the limit head 83 retracts into the sliding cavity.

[0034] When the guide block 8 slides to the position of the limiting hole 5, the spring 84 returns to its original deformation, the limiting head 83 pops out and locks into the limiting hole 5, and the installation is completed.

[0035] Disassembly process

[0036] Press the limit head 83 with your finger to overcome the elastic force of the spring 84 and make it retract into the slide cavity;

[0037] Rotate the earphone 6 counterclockwise, and the guide block 8 slides in the opposite direction along the arc-shaped guide groove 4 to disengage from the limiting hole 5;

[0038] Remove the earphone 6 from the earphone jack 2 to complete the disassembly.

[0039] Maintenance and Replacement

[0040] To replace the headphone module, press the clip on the mounting base 7 to disengage it from the slot of the headphone 6, thus separating the two.

[0041] When installing a new headphone module, align the clip with the slot and press until a "click" sound is heard, indicating that the connection is complete.

[0042] The helmet body 1 is injection molded from ABS engineering plastic. The guide hole 3, arc-shaped guide groove 4 and limiting hole 5 are precision machined by CNC to ensure dimensional accuracy.

[0043] Guide block 8 and limit head 83 are made of POM plastic injection molding, and the surface is treated with frosting to enhance wear resistance;

[0044] Spring 84 is made of SUS304 stainless steel wire with an elastic modulus of 5N / mm, ensuring that the limit head 83 can be reliably engaged;

[0045] The anti-slip texture is processed using laser engraving technology, with a depth of 0.3mm, a rubber pad thickness of 1mm, and a Shore hardness of 60A.

[0046] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
