Technical Field

[0001] The utility model belongs to the technical field of electric bicycles, and in particular relates to a load-bearing bracket for electric bicycles with a stable structure. Background Art

[0002] Battery cars are also called "electric cars". They are pure electric vehicles powered by batteries (batteries) and driven by electric motors (DC, AC, series-excited, externally-excited). Battery cars are mainly used for sightseeing, patrolling, and transporting goods. Load-carrying electric cars are electric cars with large cargo capacity, powered by human pedaling, and used for urban express delivery.

[0003] Most of the current load-carrying brackets are composed of support columns and load-carrying platforms. The support columns are connected to the frame of the electric bicycle, while the load-carrying platforms are used to place cargo. However, in some cases, since the fixed spacing of the support columns cannot be adjusted, when the load is uneven or the road conditions are bad, the support columns may not be able to effectively support the load-carrying platform, resulting in poor stability, or even tilting or sliding, which affects riding safety and comfort. Therefore, we design a load-carrying bracket for electric bicycles with a stable structure to provide another technical solution to the above technical problems. Utility Model Content
