Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically a four-wheel independent suspension power-assisted bicycle. Background Technology

[0002] A four-wheeled electric bicycle is a mode of transportation that combines a four-wheeled design with an electric power assist system. Existing four-wheeled electric bicycles generally adopt traditional welding processes for construction. However, under high stress, this type of welded structure is prone to loosening and deformation, resulting in a significant decrease in overall stability and durability after long-term use. Especially under complex road conditions or high-intensity use conditions, the fragility of the frame structure is more significant, affecting the safety and reliability of the vehicle.

[0003] Existing four-wheeled electric bicycles have significant shortcomings in their shock absorption systems and handling design. Most vehicles are equipped with shock absorption systems that lack independent suspension, making it impossible to flexibly adjust to changes in terrain while riding. Furthermore, the steering designs are generally rudimentary, lacking the coordination of a differential, which affects the coordination of the wheels when turning. At the same time, they generally use hub motors as the drive source, but these motors are inadequate in terms of heat dissipation, durability, and power distribution, which affects the applicability of four-wheeled electric bicycles in various road conditions and the safety and comfort of riding for long periods of time. Therefore, this utility model is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the process of riding on various road conditions and over long distances, a four-wheeled assisted bicycle is required. The bicycle provided by this utility model has significantly improved stability, comfort, safety and adaptability to various road conditions compared with the existing technology, so as to meet the higher requirements of users for adaptability to complex terrain and long-distance riding needs. In the process of using this bicycle, it is necessary to carry out preparatory work such as inspection in advance to ensure the normal use of this bicycle.

[0022] like Figures 1-6 As shown, this utility model provides a technical solution: a four-wheel independent suspension power-assisted bicycle, including a frame 1, a wheel assembly mounted on the frame 1, the wheel assembly including front wheels 2 symmetrically arranged on both sides of the front end of the frame 1, a first independent suspension 201 between each front wheel 2 and the frame 1, rear wheels 202 symmetrically arranged on both sides of the rear end of the frame 1, a second independent suspension 203 between each rear wheel 202 and the frame 1, shock absorbers 204 between each front wheel 2 and rear wheel 202 and the frame 1, functional components mounted on the upper part of the frame 1, a steering system mounted on the front end of the frame 1, a gear shift assembly mounted on the rear end of the frame 1, and a braking system mounted on the frame 1. In this bicycle, the main body adopts a welding process using an all-aluminum alloy mortise and tenon structure. This process, through the self-locking characteristics of the mortise and tenon, significantly improves the bonding force and overall stability of the frame 1 under high stress environment. The aluminum alloy material is sandblasted and anodized, which not only makes it lightweight and corrosion resistant, but also ensures stability during long-term use, providing the whole vehicle with stronger impact resistance and durability. The first independent suspension 201 and the second independent suspension 203 in the wheel assembly respectively enable the front wheel 2 and the rear wheel 202 to independently cope with changes in terrain, effectively absorbing the impact from uneven road surfaces, significantly improving the stability and comfort of riding, and meeting the riding needs of users in various road conditions.

[0023] In this embodiment, the functional components include a first placement plate fixed to the front end of the frame 1, on which a first storage box 101 is mounted; a second placement plate fixed to the rear end of the frame 1, on which a second storage box 102 is mounted; and a suitable seat cushion 103 provided on the top of the frame 1. The first storage box 101 and the second storage box 102 are used to place and carry the user's belongings, and the seat cushion 103 ensures the user's comfort during long periods of sitting.

[0024] In this embodiment, the steering system includes an indirect steering lever 5 located at the front end of the frame 1, with a handlebar 501 mounted on top of the indirect steering lever 5. A paddle shifter for changing the steering ratio is located at the front of the frame 1. The transmission assembly includes a centrally mounted torque motor 4 located in the center of the bottom surface of the frame 1, a matching pedal rack located in the center of the frame 1, and a matching connecting chain between the pedal rack and the rear end of the frame 1. The transmission assembly controls and achieves seven-speed gearing. The centrally mounted torque motor 4 makes the center of gravity of the vehicle more balanced, significantly improving the vehicle's handling performance. Simultaneously, the centrally mounted torque motor 4 has a large torque output, making it particularly suitable for providing strong assistance in mountainous and hilly terrain, extending the riding time in high-performance mode. The paddle shifter reduces the direct feedback of road vibrations to the steering system, making the vehicle's handling response smoother, thereby improving overall stability and riding experience. The seven-speed adjustment allows for flexible adjustment of riding resistance, enabling the user to maintain ideal speed and comfort on both flat and undulating terrain, thus improving riding efficiency and experience.

[0025] In this embodiment, a differential 3 is provided at the bottom rear end of the frame 1. The differential 3 is equipped with a universal telescopic coupling 301 and a six-axis linkage system 302 adapted to be installed at the rear end of the frame 1. The braking system includes a brake lever 601 provided on the handlebars 501. The brake lever 601 is used for power off and parking. Disc brake modules 6 are provided between the front wheel 2 and the rear wheel 202 and the frame 1. Multiple piston calipers 602 are provided on the frame 1. The differential 3 enables the front wheel 2 and the rear wheel 202 to achieve a speed difference when turning, avoiding slippage and tilting, and ensuring that the whole vehicle remains stable in complex road conditions or high-speed turns. The setting of piston calipers 602 in the braking system ensures that the whole vehicle provides strong and stable braking force in various terrains and high-speed conditions, significantly improving vehicle safety.

[0026] Working Principle: When using this bicycle, the frame 1, constructed using mortise and tenon welding technology, ensures stability, durability, and adaptability to high stress conditions. The four-wheel independent suspension design, combined with shock absorbers 204, provides efficient cushioning, enhancing adaptability to various road conditions and ensuring a comfortable and stable ride. The addition of a differential 3, along with a universal telescopic coupling 301 and a six-axis linkage system 302, significantly improves cornering performance, prevents slippage, and enhances handling agility. The use of a centrally located torque motor 4 improves overall heat dissipation. Adjusting the paddle shifters allows for smooth feedback of road vibrations. Seven gears are controlled by the gear assembly, flexibly adapting to various terrains and riding speed requirements. The braking system, using brake levers 601 and piston calipers 602, provides powerful and stable braking force. This bicycle combines stability, comfort, and excellent handling, meeting users' higher demands for adaptability to complex terrain and long-distance riding.
