Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bicycles, in particular to an adjustable bicycle rack and a bicycle. BACKGROUND

[0002] At present, the existing bicycle large-load rear racks have one size corresponding to one rack. The most circulated in the market are 29 inches, 27.5 inches, 26 inches, 24 inches, 22 inches, 20 inches and 18 inches, and there are numerous specifications, and each specification is divided into large and small hole installations. The specifications and styles are various, the enterprises produce, the dies are diversified, and in order to adapt to the market, the production of multiple specifications causes huge inventory. Correspondingly, the bicycle sellers also cause the influence of warehouse and specification cost when purchasing the racks. In general, the traditional multiple specification matching is not conducive to the guidance of energy saving and emission reduction, and the upstream and downstream of the rack demand will more or less stock products. For bicycle users, when changing a bicycle, if a rack is needed, a new rack must be purchased according to the specification of the new bicycle, which cannot be recycled and causes waste.

[0003] At present, the bicycle racks on the market are assembled through alloy casting, forging, welding and the linkage of more than twenty fasteners, and there are many manual connection points. Moreover, too many screw control points of the installation structure cause poor load capacity of the rack. In addition, since the installation of the rack is basically completed by the consumers themselves, there are more than twenty installation points, and there is a risk of safety hazard if the screw fastening of one point is neglected in the installation process. In addition, the rack on the market is clamped on the seat tube under the seat cushion through a panel, and the lifting height of the seat cushion is required. In the actual use process, if the seat cushion cannot be lifted due to the individual height, the rack cannot be installed. The support rod of the rack is clamped on the bicycle rear fork by a lock clamp, and if the shift line and brake line of the bicycle are located, the lock clamp installation position will overlap, which will cause delay of the brake and shift or cause safety hazard.

[0004] The patent with publication number CN219172570U discloses a universal bicycle rack, which can only be adjusted in height and cannot adapt to the needs of different bicycle sizes, resulting in limited application range. In addition, the installation of the bicycle rack requires fasteners to be installed on the seat tube and rear fork, and the following problems still exist: first, the round seat tube can be installed, but the triangular and quadrangular seat tubes cannot be installed; second, the seat tube position must be occupied, and the seat cushion height must be raised during installation, which has a hard requirement for height; third, the rack stand is installed on the rear fork through fasteners, and the diameter of the rear fork has a hard requirement. The personalized rear fork with too large or too small diameter cannot be installed.

[0005] It can be seen that, with the diversification of cycling needs, the traditional fixed cargo rack is difficult to meet the carrying needs of different loads and sizes, resulting in limited cycling experience. Therefore, developing a bicycle cargo rack with flexible structure and convenient adjustment has become an urgent problem in the industry. Utility model content
