Description

A bicycle wear LED smart helmet

Technical field

The invention relates to the technical field of cycling supplies, in particular to a bicycle wearing LED smart helmet.

Background technique

Since the bicycle was invented, it has gradually become a better means of transportation and leisure for people, especially after cycling has become a competitive sport, people love it even more. But as a sport that is determined by speed, safety has become an important issue. So people think of helmets. Cycling helmets generally consist of 7 parts, the cap shell: the hard shell of the outermost layer of the helmet. In the event of an accidental collision, the hood is the first line of defense to protect the head to disperse the impact. Cap body: the foam inner layer inside the helmet. It is the second line of defense to protect the head. It is mainly used to absorb the impact force in accidents and reduce accident injuries. Buckle and hat strap: used to fix the position of the helmet. The cap strap is fixed under the ears on both sides, and the position of the buckle is fixed at the throat. Note: After buckling the buckle, leave 1 to 2 finger space on the buckle and throat. Remember not to be too tight or too loose. Brim: The brim is divided into two types: fixed and adjustable. General road bike riding helmets do not have a brim. The role of the hat brim is to prevent foreign objects from flying into the rider's eyes, and at the same time play a certain shade. Stomata: Stomata is used to help the head heat and ventilate, and can keep the hair dry during long-distance riding. The more air holes, the cooler the rider will feel, but the lower the relative safety factor. Generally, it is better to choose a helmet with the right amount of air holes. Knob: There is a knob for adjusting the tightness on the back of the riding helmet. Riders can adjust the size of the helmet according to the size of their head. Pad: The pad can absorb sweat and slight vibration from the human body during riding. The appearance of bicycle helmets not only guarantees the safety of cyclists, but also improves the performance of racing athletes. Cycling helmets are the most solid protective barrier for life in cycling. Falling during riding can cause great damage to the head. Even if the rider is riding at a low speed along a smoothly sloped bike path, safety issues cannot be ignored. The reason for wearing a riding helmet is very simple and very important. It protects the head and reduces injuries. Medical research has found that wearing a helmet while riding a bicycle can prevent 85% of head injuries and greatly reduce the degree of injury and accident mortality. Half-face riding helmets are divided into road-specific, road-mountain dual-use, etc.

Due to the limitations of the bicycle, there are no steering and deceleration prompts when driving on the road. Although the rider wears an ordinary safety helmet, it is difficult to identify other owners and may cause traffic safety hazards.
