[0002] Cycling is increasingly popular due to its environmental impact, significant fitness benefits, and convenient commuting. Modern cycling combines elements of health, social interaction, and adventure, attracting a large number of cycling enthusiasts. Whether it's city cycling or long-distance travel, cycling not only provides a free and easy way to exercise, but also promotes green travel and a sustainable lifestyle. Professional cycling equipment and activities also enrich the cycling experience, making it a fashionable and practical lifestyle. However, prolonged cycling can be harmful to the human body. Excessive riding time can cause continuous pressure on the crotch from the seat, which may cause discomfort or pain. Prolonged pressure can affect blood circulation in the crotch, and in severe cases, may cause damage to the skin and tissues. More seriously, it may affect men's reproductive health, such as testicular pain or erectile dysfunction. For women, prolonged cycling may cause discomfort or infection in the genitals.

[0003] For example, patent application number CN201310289279.5 discloses a bicycle seat comprising a cushion frame and left and right cushions. The left and right cushions are arranged side by side on the cushion frame with a gap between them. An opening is formed between the front ends of the left and right cushions. The present invention has a simple structure, good ventilation, and strong pressure relief. The opening between the front ends of the left and right cushions can reduce the pressure on the crotch. However, this bicycle seat has limited pressure relief after long periods of riding and does not protect the hip joint. Utility Model Content

[0004] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a shared bicycle with human body protection function.

[0036] The frame body 1 includes a seat support structure 101 connected to the seat 3 and a handlebar support rod 102 connected to the handlebar 4. The seat support structure 101 includes a main support rod 1011 and a tilt-limiting support rod 1012. The main support rod 1011 is vertically arranged, with its top connected to the end of the tilt-limiting support rod 1012. The side of the tilt-limiting support rod 1012 is provided with an inwardly recessed limiting groove 100. The seat 3 is connected to the main support rod 1011 via an adjustment assembly 5. The adjustment assembly 5 includes a sliding sleeve 501 and a rotating arm 502. One end of the rotating arm 502 is axially connected to the sliding sleeve 501, and the other end of the rotating arm 502 is connected to the sliding groove 3021 and the limiting groove 100, respectively. The two-part seat cushion body 301 cooperates with the sliding arm 302, so that the seat cushion body 301 can follow the movement of the rider's hips during riding. The rotating arm 502 is connected to the sliding groove 3021 and the limiting sliding groove 100. The seat cushion body 301 drives the sliding arm 302 to move clockwise or counterclockwise synchronously when following the movement of the rider's buttocks. At the same time, the two-petal split design allows the seat cushion body 301 on each side to support the buttocks on each side respectively and move along with the rotation of the femur, which is more in line with the movement of the hip joint and will not cause pressure damage to the human hip joint.

[0037] The handlebar 4 includes a handlebar insert 401. The hollow handlebar support 102 is provided with an adjustment hole 1021. The handlebar insert 401 is provided with a removable protrusion 4011 corresponding to the adjustment hole 1021, and the protrusion 4011 is connected to the adjustment hole 1021.
