Description

Technical Field

[0001] This utility model belongs to the field of protective equipment technology, specifically relating to a retractable sun visor for a motorcycle helmet. Background Technology

[0002] Motorcycle helmets are essential safety equipment for motorcyclists, protecting the rider's head in the event of an accident and improving the riding experience. A motorcycle visor is a particularly practical feature in modern helmet design, helping to reduce the discomfort of direct sunlight on the eyes during long rides or in strong sunlight, making it especially suitable for those who need to ride outdoors for extended periods.

[0003] Common sunglasses are usually worn outside the helmet and can be adjusted by sliding them up and down. Although the adjustment method is simple, the traditional sliding adjustment mechanism will be damaged or worn over time, causing the visor to be unable to be adjusted or retracted smoothly. In some cases, the visor may even slide down during the wearing of the helmet, which can lead to instability and an unsafe riding experience when riding at high speeds. Utility Model Content

[0004] The purpose of this invention is to provide a retractable sun visor for a motorcycle helmet, which can automatically retract the sun visor inside the helmet and effectively position the lens when adjusting the sun visor. The sun visor will not easily fall off or slide during riding, ensuring that the rider always has a clear field of vision and sun protection.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A retractable sun visor for a motorcycle helmet includes a sun visor lens disposed inside the helmet shell. Both ends of the sun visor lens are fixedly connected to rotating rods. The other ends of the two rotating rods extend to both sides of the helmet shell. Structural boxes are installed on both sides of the helmet shell. The outer ends of the rotating rods are connected to the inner walls of the structural boxes via bearings. A telescopic adjustment mechanism is provided inside the structural boxes. The telescopic adjustment mechanism includes coil springs and baffles. The coil springs are wound around the surfaces of the two rotating rods, with one end connected to the surface of the rotating rod and the other end connected to the inner wall of the structural box. The baffles are respectively sleeved on the surfaces of the two rotating rods, and the baffles are tightly fitted to the outer side of the coil springs.

[0007] Preferably, a positioning mechanism is provided inside the structural box on one side. The positioning mechanism includes a positioning ratchet that is movably sleeved on the surface of the rotating rod. The outer side of the positioning ratchet is fixedly connected to the inner wall of the structural box. A rotating ratchet is engaged with the inner side of the positioning ratchet. The rotating ratchet is sleeved on the surface of the rotating rod. A compression spring is fixedly connected to the inner side of the rotating ratchet. The other end of the compression spring is fixedly connected to the outer side of the baffle. The compression spring is movably sleeved on the surface of the rotating rod.

[0008] Preferably, a sliding block is fixedly connected to the inner wall of the rotating ratchet, and a groove is formed on the surface of the rotating rod, with the sliding block slidably connected inside the groove.

[0009] Preferably, one end of the rotating rod has a circular hole, and a push rod is slidably connected inside the circular hole. The push rod is fixedly connected to the sliding block, and the outer end of the push rod extends through to the outside of the structural box.

[0010] Preferably, the surfaces of the two rotating rods are provided with slots, and one end of the coil spring is connected to the inside of the slot.

[0011] Preferably, a through hole is provided on the outer side of one side of the structural box, and the push rod is movably disposed inside the through hole.

[0012] Preferably, one end of the push rod is fixedly connected to a button via a bearing, and the button is circular in shape.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, when wearing a helmet and needing to use the visor, pulling down the visor extends it to the front of the helmet shell. The downward movement of the visor simultaneously rotates the rotating rods and baffles on both sides. As the rotating rods rotate, they pull the coil springs to retract onto the rod surface. Simultaneously, the rotating rods drive a ratchet to rotate forward. As the ratchet rotates forward, it is pressed by a positioning ratchet, and with the cooperation of a sliding block and a sliding groove, the ratchet slides inward on the rotating rod surface. This inward sliding of the ratchet compresses the compression spring. After the visor is pulled down to the desired position, the compression spring's force continuously pushes the ratchet outward, engaging it with the positioning ratchet. This positions the extended visor, ensuring it is fixed in the correct position and preventing positional changes or slippage during riding, thus ensuring the rider enjoys optimal sun protection.

[0015] In this invention, after the sun visor is extended inside the front of the helmet shell, simply press the push rod inward. The push rod will cause the sliding block to slide inward inside the groove, and the sliding block will cause the rotating ratchet to slide inward on the surface of the rotating rod. This disengages the rotating ratchet from the positioning ratchet, and at the same time, the energy of the coil spring wound on the surface of the rotating rod will be released, which will cause the rotating rod to rotate backward. The rotation of the rotating rod will cause the sun visor to automatically slide up and retract inside the helmet shell. The rider can retract the sun visor without manual adjustment, which effectively improves comfort and convenience. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-6As shown, a retractable sun visor for a motorcycle helmet includes a sun visor lens 101 disposed inside the helmet shell 1. Both ends of the sun visor 101 are fixedly connected to rotating rods 102. The other ends of the two rotating rods 102 extend to both sides of the helmet shell 1. Structural boxes 2 are installed on both sides of the helmet shell 1. The outer ends of the rotating rods 102 are connected to the inner wall of the structural box 2 via bearings. A telescopic adjustment mechanism is provided inside the structural box 2. The telescopic adjustment mechanism includes a coil spring 201 and a baffle 202. The coil spring 201 is wound around the surface of the two rotating rods 102, and one end of the coil spring 201 is connected to the rotating rod 102. The surface of the 2 is connected, and the other end of the coil spring 201 is connected to the inner wall of the structure box 2. The baffle 202 is respectively sleeved on the surface of the two rotating rods 102, and the baffle 202 is tightly fitted to the outer side of the coil spring 201. When the sun visor 101 is pushed down from the inside of the helmet shell 1, it can drive the rotating rod 102 to rotate forward. The forward rotation of the rotating rod 102 can drive the coil spring 201 to be tightly wound on the surface of the rotating rod 102 to store energy, which is convenient for the flipping of the rotating rod 102 and the automatic retraction of the sun visor 101, so that the rider can conveniently and quickly retract and adjust the sun visor 101.

[0026] like Figures 2-5 As shown, a positioning mechanism is provided inside the structural box 2 on one side. The positioning mechanism includes a positioning ratchet 203 movably sleeved on the surface of the rotating rod 102. The outer side of the positioning ratchet 203 is fixedly connected to the inner wall of the structural box 2. A rotating ratchet 204 is engaged on the inner side of the positioning ratchet 203. The rotating ratchet 204 is sleeved on the surface of the rotating rod 102. A compression spring 205 is fixedly connected to the inner side of the rotating ratchet 204. The other end of the compression spring 205 is fixedly connected to the outer side of the baffle 202. The compression spring 205 is movably sleeved on the surface of the rotating rod 102. A sliding block 301 is fixedly connected to the inner wall of the rotating ratchet 204. A groove 302 is opened on the surface of the rotating rod 102. The sliding block 301 is slidably connected to the inside of the groove 302. When the sunshade lens 101 is pushed down to unfold, the coil spring 201 retracts. During the process of retracting onto the surface of the rotating rod 102, the rotating rod 102 simultaneously drives the rotating ratchet 204 to rotate forward. As the rotating ratchet 204 rotates forward, it is pressed by the positioning ratchet 203, and with the cooperation of the sliding block 301 and the sliding groove 302, the rotating ratchet 204 slides inward on the surface of the rotating rod 102. Thus, with the cooperation of the sliding block 301 and the sliding groove 302, the rotating ratchet 204 can rotate flexibly and slide left and right. This facilitates the continuous elastic force of the compression spring 205 to push the rotating ratchet 204 to engage with the positioning ratchet 203. Then, the rotating rod 102 positions the sun visor 101, preventing the sun visor 101 from accidentally shifting or shaking during riding. This increases the stability during use and ensures that the sun visor 101 is always in the required angle and position.

[0027] like Figure 4 and Figure 5 As shown, a circular hole 401 is provided at one end of the rotating rod 102. A push rod 402 is slidably connected inside the circular hole 401. The push rod 402 is fixedly connected to the sliding block 301. The outer end of the push rod 402 extends to the outside of the structure box 2. When the push rod 402 is rotated inward, the push rod 402 will slide inside the circular hole 401, which can drive the sliding block 301 to move freely inside the slide groove 302. By pressing the push rod 402, the sun visor 101 can be quickly retracted, allowing the rider to retract the sun visor 101 in a short time, making it easier to cope with changing light conditions and improving the convenience of use.

[0028] like Figure 6 As shown, the surfaces of the two rotating rods 102 are provided with slots 5. One end of the coil spring 201 is connected to the inside of the slot 5. The slot 5 and the coil spring 201 are connected in a cooperative manner, which can provide a reaction force after the rotating rod 102 rotates, helping the rotating rod 102 to return to the initial position. This self-resetting design allows the rotating rod 102 to automatically return to its original position after use, preventing jamming or displacement during long-term use, improving the convenience of operation, and allowing the sunshade lens 101 to be retracted quickly and smoothly.

[0029] like Figure 4 and Figure 5 As shown, a through hole 6 is provided on the outer side of one side of the structural box 2. The push rod 402 is movably disposed inside the through hole 6. One end of the push rod 402 is fixedly connected to a button 7 via a bearing. The button 7 is round. The fit between the push rod 402 and the through hole 6 allows for sufficient space when the push rod 402 is pushed to move, preventing the push rod 402 from rubbing against the inner wall of the structural box 2 during movement, which would affect the smooth operation of the telescopic adjustment mechanism. The button 7 has a larger contact area when the push rod 402 is pressed, allowing the push rod 402 to be pushed more effortlessly. It can also be connected to the rotating shaft of the button 7 via the rotating rod 102, preventing the process of the rotating rod 102 driving the push rod 402 to rotate in the opposite direction when the sun visor 101 is retracted, thus preventing interference and resistance from the pressing pressure of the button 7. This allows the sun visor 101 to be easily retracted into the helmet shell 1.

[0030] The working principle of this utility model is as follows: When wearing a helmet and needing to use the sun visor 101, pulling down the sun visor 101 will extend it to the front inside the helmet shell 1. The downward movement of the sun visor 101 simultaneously drives the rotating rods 102 and the baffle 202 on both sides to rotate. When the rotating rods 102 rotate, they pull the coil spring 201 to retract onto the surface of the rotating rod 102. Simultaneously, the rotating rods 102 drive the rotating ratchet 204 to rotate forward. As the rotating ratchet 204 rotates forward, it is pressed by the positioning ratchet 203. With the cooperation of the sliding block 301 and the sliding groove 302, the rotating ratchet 204 slides inward on the surface of the rotating rod 102. This inward sliding of the rotating ratchet 204 compresses the compression spring 205. After the sun visor 101 is pulled down to the desired position, the rotation ratchet 204 is continuously pushed outward by the elastic force of the compression spring 205, causing the rotating ratchet 204 to engage with the positioning ratchet. The engagement of wheel 203 positions the extended visor 101, ensuring it stays in the correct position and preventing positional changes or slippage during riding. After extending the visor 101 to the front of the helmet shell 1, simply press the push rod 402 inward. The push rod 402 will cause the sliding block 301 to slide inward within the groove 302, and the sliding block 301 will cause the rotating ratchet 204 to slide inward on the surface of the rotating rod 102. This disengages the rotating ratchet 204 from the positioning ratchet 203, and releases the energy of the coil spring 201 wound on the surface of the rotating rod 102, causing the rotating rod 102 to rotate backward. The backward rotation of the rotating rod 102 will cause the visor 101 to automatically slide upward and retract inside the helmet shell 1. Riders can retract the visor 101 without manual adjustment, effectively improving comfort and convenience.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
