Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a helmet brim fixing device that facilitates the assembly and disassembly of the brim. Background Technology

[0002] When riding a motorcycle or electric bike, a helmet is usually worn. To prevent rainwater from hitting the goggles or sunlight from shining directly on them when riding in the rain or under strong sunlight, a brim is usually fixed to the front of the helmet. The brim also serves to prevent foreign objects from hitting the goggles at high speed.

[0003] Existing helmet brims are typically secured using a fixed structure or adjustment device. For example, Chinese Patent CN 208403394U, "Helmet Brim Adjustment Device," discloses a helmet brim adjustment device including a helmet body, brim bases on both sides of the helmet body, and a brim on the brim bases. Each brim base has a fixing hole at one end and a sliding groove at the other end. Each brim base is fixedly connected to the brim by locking screws. The ends of both sides of the brim have through holes and adjusting blocks, with the through holes corresponding to the fixing holes on the brim bases. The adjusting blocks move within the sliding grooves and control the rotation of the brim. Each sliding groove has a limiting groove on its inner wall to ensure that the brim's rotation height remains unchanged after adjustment, allowing the brim to be pushed upwards by hand. However, existing helmet brims are connected to the helmet body via adjustment devices, and these existing brim fixing and adjustment structures have some problems during use:

[0004] Drivers sometimes need to remove the visor while driving, such as when cycling in the city to avoid obstructing traffic lights, or when cycling at night to avoid obstructing traffic lights and streetlights. However, existing visor adjustment mechanisms firmly fix the visor to the helmet body. When replacing the visor, multiple tools are needed to disassemble the adjustment mechanism and then remove the visor. The entire disassembly process is very cumbersome, and improper operation may break the visor, damaging the helmet and rendering it unusable, increasing the cost of the helmet. Furthermore, it is very inconvenient for users, requiring considerable effort from both removing and installing the visor. Utility Model Content

The entire process of locking and unlocking the brim 3 is very simple, reducing the difficulty of locking and unlocking the brim 3, eliminating the need for the driver to spend time and money learning, and facilitating the repair or replacement of the brim 3.

[0029] like Figures 4-7 As shown, in a specific implementation of this utility model, a locking key fixing groove 21 is formed on the upper inner side of each fixed base 2, which cooperates with the brim locking key structure 4. The brim locking key structure 4 is installed in the locking key fixing groove 21 on the inner side of the fixed base 2. The brim 3 includes a first brim support fixing part 34 and a second brim support fixing part 35. The first brim support fixing part 34 and the second brim support fixing part 35 are symmetrically distributed at the top of the brim sun shading part 31 and are fixedly connected to the top of the brim sun shading part 31. The brim 3 of this utility model is a one-piece injection molded part, which helps to reduce the assembly process of the brim 3 and improve the production efficiency of the brim 3. The brim 3 set by this utility model not only has a sun shading function, but also improves the appearance of the helmet 1.

[0030] In this embodiment, each set of fixed bases 2 has a fixed base 25 and a connecting post 26 on its inner side. The connecting post 26 is located on one side of the fixed base 25 and fixed in the key fixing groove 21. The fixed base 25 is fixed at the lower end of the key fixing groove 21. Specifically, the lock handle slide groove 24 and slot 22 of the fixed base 2 are distributed alternately on the fixed base 2. The brim key structure 4 includes a brim key 41, a lock handle 42, and a key elastic member 43. The lock handle 42 is located on the outer side of one end of the brim key 41 and is fixed to the brim key 41 as an integral structure. The key elastic member 43 is located on the inner side of the brim key 41. The other end of the brim key 41 forms a hinge hole 45 that cooperates with the connecting post 26 of the fixed base 2.

[0035] This utility model achieves the locking of the brim 3 and the brim lock key 41 by engaging the locking hook 44 on the brim lock key 41 with the brim lock slot 38 of the brim lock block 33. By pulling down the lock handle 42 and moving the brim 3 towards the front of the helmet 1, the brim 3 is disengaged from the locking position of the brim lock key 41, which enables the quick unlocking and removal of the brim 3 by the brim lock key 41. This brim lock key structure 4 is simple in design and makes it very convenient for the driver to remove the brim 3 from the helmet 1, facilitating the replacement and maintenance of the brim 3.

[0036] like Figures 8-10 As shown, base fixing slots 11 are provided on both sides of the helmet 1, and two sets of fixing bases 2 are respectively installed in the base fixing slots 11 on both sides of the helmet 1.

[0037] This invention can also provide a first elongation adjustment hole 36 in the first brim support fixing part 34 of the brim 3, a second elongation adjustment hole 37 in the second brim support fixing part 35, and a first positioning hole 12 and a second positioning hole 13 on the top of the helmet 1. A first positioning fixing post that cooperates with the first elongation adjustment hole 36 is fixed on the first positioning hole 12, and a second positioning fixing post that cooperates with the second elongation adjustment hole 37 is fixed on the second positioning hole 13. The first elongation adjustment hole 36 of the first brim support fixing part 34 at the top of the brim sunshade part 31 will be aligned with the top of the helmet 1. The first positioning and fixing post on the first positioning hole 12 is engaged with the second long adjustment hole 37 of the second brim support fixing part 35 at the top of the brim sunshade part 31, which is engaged with the second positioning and fixing post on the second positioning hole 13 at the top of the helmet 1. This makes it very convenient to assemble and disassemble the brim 3 with the forehead of the helmet 1. The brim 3 can be fixed at four points through the brim locking blocks 33 on both sides, the first long adjustment hole 36 of the first brim support fixing part 34, and the second long adjustment hole 37 of the second brim support fixing part 35, thereby improving the stability of the brim 3.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
