Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, specifically a novel electric bicycle saddle structure and an electric bicycle. Background Technology

[0002] Electric bicycles offer a certain range and are convenient to ride, making them widely used for short-distance transportation. Because the shock absorption performance of the front and rear wheel suspension systems in existing electric bicycles is quite good, the shock-absorbing springs at the bottom of the saddle have been largely removed. To improve the aesthetics of the saddle bottom after the removal of the springs, a decorative piece is usually installed. Current saddle bottom decorative pieces typically use a full-coverage design, which means the inner side of the decorative piece is tightly fitted to the outer wall of the saddle support tube. This prevents the decorative piece from being pre-installed. Pre-installation would prevent the connection between the upper part of the saddle support tube and the saddle bottom support structure. In actual production, the saddle must be installed on the upper part of the saddle support tube on the assembly line before the decorative piece is installed, which does not improve the assembly line efficiency.

Specifically, the main body plate 2 is connected to the saddle support plate 5 on the electric bicycle frame by bolts, and the saddle support plate 5 is fixedly connected to the support tube 51 on the frame by welding. The seat cushion mounting plate 4 is also included. The plate 3 has a ring-shaped structure, and the seat cushion mounting plate 3 is fitted onto the upper outer edge of the main body plate 2. The seat cushion mounting plate 3 is connected to the main body plate 2 by bolts. The decorative part 4 has a ring-shaped structure, and the saddle support plate 5 can pass through the decorative part 4. The decorative part 4 is fixedly installed on the lower outer edge of the main body plate 2 by screws. An annular receiving gap 101 is reserved between the lower inner side of the seat cushion mounting plate 3 and the upper outer side of the decorative part 4. The elastic seat cushion 1 covers the upper part of the seat cushion mounting plate 3, and the bottom lower edge of the elastic seat cushion 1 is clamped in the annular receiving gap 101. The lower edge of the elastic seat cushion 1 is located in the annular receiving gap 101, which helps to improve the overall aesthetics of the saddle and also improves the stability of the elastic seat cushion 1 covering the seat cushion mounting plate 3. In practical applications, since the saddle support plate 51 can smoothly penetrate the interior of the decorative part 4, it is convenient to pre-assemble the entire saddle structure.
