Description

Technical Field

[0001] This utility model relates to the field of personal protective equipment, and in particular to a simple and durable chin switch structure for flip-up helmets. Background Technology

[0002] Flip-up helmets are popular among motorcyclists because they combine the protection of full-face helmets with the convenience of open-face helmets. Their core component is the chin guard and main helmet body's locking mechanism. Traditional chin guard mechanisms have the following drawbacks:

[0003] 1. Complex structure: Many products use multi-link, gear or complex slide rail mechanisms, with a large number of parts, complicated assembly and high production costs.

[0004] 2. Easily damaged: Small parts in complex mechanisms, such as small springs and plastic clips, are prone to breakage or failure during frequent use or accidental drops, rendering the entire helmet unusable.

[0005] 3. High cost: The precision structure requires multiple molds and the use of more types of materials (such as metals, high-strength engineering plastics, etc.), which increases the manufacturing cost.

[0006] To address the aforementioned problems, we propose a simple and durable chin switch structure for flip-up helmets. Utility Model Content

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A simple and durable chin switch structure for flip-up helmets includes a main helmet body 1, a chin guard 2 mounted on the surface of the main helmet body 1, and mounting bases 3 bolted to both sides of the main helmet body 1. Locking tongues 4 are bolted to the surface of the mounting bases 3. Connecting seats 5 are rotatably connected to both sides of the chin guard 2. Locking grooves 6 are formed on the surface of the connecting seats 5, and the locking grooves 6 engage with the locking tongues 4. A spring 7 is provided between the connecting seats 5 and the chin guard 2. A button 8 is rotatably connected between the connecting seats 5, and the button 8 is slidably connected to the inner wall of the chin guard 2. The entire switching mechanism consists of only three core moving parts: the button 8, the locking tongue 4, and the spring 7, along with a simple connecting seat 5 and mounting bases 4. Composed of seat 3, the number of parts is greatly reduced, greatly simplifying the production and assembly process. All structural components can be molded in one piece through a simple injection molding process, without the need for complex molds and expensive materials. Spring 7 is a standard part, with low procurement costs. The overall manufacturing cost is far lower than that of traditional complex mechanisms. It eliminates small connecting rods and fragile buckles. The core load-bearing components, locking tongue 4 and connecting seat 5, can be designed to be robust and sturdy. With fewer moving parts and fewer wear points, the product's service life and impact and drop resistance are greatly improved. The simple press-to-unlock logic is easy for users to understand and operate. The spring 7 reset ensures the automatic completion of the locking action, resulting in high reliability.

[0032] refer to Figure 4 The surface of button 8 is provided with anti-slip texture 9. By setting anti-slip texture 9, it is possible to prevent the hand from slipping and make it easy to operate.

[0033] refer to Figure 3 The locking tongue 4 is a cylindrical metal part, and the end of the locking tongue 4 is umbrella-shaped. By setting the locking tongue 4 to be a cylindrical metal part and the end of the locking tongue 4 to be umbrella-shaped, it is convenient to engage with the connecting seat 5.

[0034] refer to Figure 3 The spring 7 is made of stainless steel, which makes it convenient to use.

[0035] refer to Figure 3 The lock groove 6 is U-shaped, which facilitates its engagement with the lock tongue 4.

[0036] refer to Figure 3 The connector 5 is made of high-strength engineering plastic, which provides advantages such as high strength, light weight and durability.

[0037] Brief description of the usage process: When button 8 is pressed, button 8 causes the locking tongue 4 to retract inward and compress the spring 7, so that the locking groove 6 on the connecting seat 5 disengages from the locking tongue 4, thereby unlocking and opening the chin cover 2. At this time, the chin cover 2 can be rotated upward and flipped open. When closing the chin cover 2, the head of the locking tongue 4 first contacts the connecting seat 5 and is squeezed and retracted. After the chin cover 2 is fully closed, the connecting seat 5 automatically drives the locking groove 6 to engage with the locking tongue 4 under the action of the spring 7, completing the locking and fixing the chin cover 2.

[0038] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
