Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a corrosion-resistant composite coated aluminum alloy bicycle frame. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is typically a small, two-wheeled land vehicle. Riders power it by pedaling, making it a green and environmentally friendly mode of transportation. There are many types of bicycles, including single-person, tandem, and multi-person bicycles. They can be used for commuting and getting around in an environmentally friendly way; increasingly, people are using bicycles as fitness equipment for exercise and cycling tours; and cycling itself is also a competitive sport, with events such as road cycling, mountain biking, track cycling, and stunt cycling.

[0003] Existing bicycles inevitably encounter uneven road surfaces during use, leading to frequent bumps and reduced control, even causing tipping over. While most bicycles are equipped with shock absorbers, these are often only located at the front and rear wheels. This means that vibrations still affect the rider when transmitted to the saddle. Furthermore, the fixed saddle is prone to impact and compression of the rider's groin and buttocks during vibrations, causing discomfort. To address these issues, we propose a corrosion-resistant composite-coated aluminum alloy bicycle frame. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a corrosion-resistant composite coated aluminum alloy bicycle frame.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A corrosion-resistant composite coated aluminum alloy bicycle frame includes a frame 1. A rotating rod 2 is rotatably mounted at one end of the frame 1. A front wheel 3 is rotatably connected to the bottom of the rotating rod 2 via a bracket. A handlebar 4 is mounted at the top of the rotating rod 2. A rear wheel 7 is rotatably mounted at the bottom of the other end of the frame 1 via a bracket. A drive shaft 5 is connected to one side of the rear wheel 7 via a transmission mechanism 8. The drive shaft 5 is rotatably mounted on the frame 1, and pedals 6 are installed at both ends of the drive shaft 5 in a staggered manner. When the drive shaft 5 rotates, it can transmit power to the rear wheel 7 via the transmission mechanism 8, so that the frame 1 can move by the rotation of the front wheel 3 and the rear wheel 7. The rotation of the rotating rod 2 facilitates the rotation of the front wheel 3, so as to adjust the steering when moving.

[0025] Specifically, in actual use, the transmission mechanism 8 consists of two sprockets and a chain meshing on the sprockets. The two sprockets are coaxially mounted on the rear wheel 7 and the drive shaft 5, respectively.

[0026] In actual use, the frame 1 is made of aluminum alloy and has a corrosion-resistant coating on its surface.

[0027] like Figure 2 and Figure 4 As shown, a connecting seat 9 is provided at the top center of the frame 1. A cylindrical cavity is formed at the top of the frame 1 near the connecting seat 9. A connecting rod 22 is built into the cylindrical cavity. The top of the connecting rod 22 is fixed to the connecting seat 9. A locking bolt 10 is threaded to the side of the frame 1. The end of the locking bolt 10 passes through the cylindrical cavity and corresponds to the outer wall of the connecting rod 22. This allows the height of the connecting seat 9 on the frame 1 to be adjustable, making it convenient for the user to adjust the connecting seat 9 according to their own height and improving the usability of the frame 1.

[0028] A slot 11 is provided on the top of the connecting seat 9, and the slot 11 extends through both sides of the connecting seat 9. A connecting frame 12 is rotatably installed in the slot 11 via a rotating shaft. A support plate 13 is connected to the top of the connecting frame 12. A seat cushion 14 is installed on the top of the support plate 13. A groove 15 is provided in the center of the top of the seat cushion 14. The two ends of the groove 15 are located on both sides of the seat cushion 14, and the cross-section of the groove 15 is arc-shaped, so that the seat cushion 14 fits the user's buttocks better and improves the comfort of the seat cushion 14 during use.

[0029] Furthermore, the seat cushion 14 is a sponge block, which is placed in a breathable mesh cover to ensure the breathability of the seat cushion 14. Nuts are fixed inside the mesh cover so that the mesh cover is fixed to the support plate 13 by bolts, which improves the ease of disassembly and assembly of the seat cushion 14.

[0030] like Figure 4 As shown, two symmetrically arranged connecting plates 16 are provided on both sides of the connecting frame 12. The two connecting plates 16 are connected by compression springs 17. On the side of the two connecting plates 16 that are relatively far apart, a fixed seat 18 is vertically installed. The fixed seat 18 is rotatably installed in the U-shaped seat 19 through a rotating shaft. One U-shaped seat 19 is fixed to the end of the support plate 13, and the other U-shaped seat 19 is fixed to the connecting seat 9. Due to the rotational connection of the seat cushion 14 on the connecting seat 9, the seat cushion 14 can tilt back and forth, that is, it automatically adjusts according to the specific sitting posture of the user when sitting on the seat cushion 14, so that the support plate 13 always remains parallel to the user's buttocks and will not cause compression to the user. When the seat cushion 14 tilts back and forth, it will exert a force on the compression springs 17 at both ends, thereby deforming the compression springs 17, ensuring that the seat cushion 14 has a tendency to return to the initial state, and also providing elastic support for the seat cushion 14, improving the comfort of the seat cushion 14.

[0031] It should be noted that sleeves 20 are provided on both sides of the connecting seat 9. The sleeves 20 are placed inside the compression spring 17, and one end of the sleeve 20 is fixed on the connecting plate 16. The other end of the sleeve 20 has a guide shaft 21 built in it. The other end of the guide shaft 21 is connected to another connecting plate 16 to provide guidance for the extension and retraction of the compression spring 17, ensuring the stability of the movement of the compression spring 17, and allowing the compression spring 17 to always act on the support plate 13 with a force in the vertical plane.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
