Description

Frame folder

Technical Field

The invention relates to the technical field of folding devices of bicycles, in particular to a frame folder.

Background

Folding bicycles (folding bicycles) belong to one category of bicycles. The general folding bicycle is composed of a frame folding joint and a vertical pipe folding joint. The front wheel and the rear wheel are folded together through the folding of the frame, so that the length of the frame can be reduced by about 45 percent. After the whole car is folded, the whole car can be put into a boarding case and a folding bag, and a trunk of the car. The vehicle can be folded and unfolded manually without using external tools in the folding process. After folding, the seat rod is used as a supporting point so that the folded seat can stand stably. The folding bicycle is convenient and comfortable to carry and use, and the production process is mature.

Currently, existing folding bicycles generally comprise the following parts:

1. frame component: the frame is the most basic structure of the bicycle, and is also the framework and the main body of the bicycle, and other parts are directly or indirectly arranged on the frame. The frame parts have a plurality of structural forms, but the frame parts can be divided into two main types of frames of men and women according to the use population. The frame is generally formed by welding and combining common carbon copper pipes. In order to reduce weight and improve strength, higher-grade bicycles are manufactured by aluminum alloy pipes. In order to reduce resistance to rapid travel, some bicycles also employ streamlined steel pipes. Because the bicycle runs by means of the driving force and riding skill of the human body, the frame becomes an important structural body for bearing the impact load generated by the bicycle during running and carrying the human body comfortably and safely, and the manufacturing precision of the frame parts directly influences the riding safety, stability, portability and speed. The spokes are generally equal in diameter, so that the weight is lightened, the spokes with variable diameters with large two ends and small middle are also manufactured, and the spokes are manufactured into a flat streamline shape so as to reduce air resistance.

2. Cover tyre: the patterns on the outer tire are used for increasing the friction force with the ground. The soft side tires and the hard side tires can be classified according to the hardness of the side tires. The soft tire has wider section, can fully wrap the inner tire, has larger ground contact area, strong grasping force, extremely wide outer tire width and deeper patterns, is suitable for off-road mountain lands, can be suitable for various roads to run, and is similar to mountain bike. The hard tire has the advantages of light weight, small ground contact area, weak ground grasping force, narrow width of the outer tire, shallow patterns, suitability for road ground, small resistance, light and fast running and the like, and is suitable for running on a flat road, similar to a road vehicle.

3. Pedal: the pedal is assembled on the left and right cranks of the middle shaft part, and is a device for converting translational force into rotational force. Therefore, whether the structure and the specification of the pedal part are proper or not will directly influence whether the foot placing position of the cyclist is proper or not, and whether the driving of the bicycle is smoothly performed or not. Therefore, the pedal is required to have a pedal surface, is required to be safe and reliable, has certain anti-skid performance and can be made of rubber, plastic or metal materials.

4. Front fork component: the front fork part is located in the front part of the bicycle structure, the upper end of the front fork part is connected with the handlebar part, the frame part is matched with the front pipe, and the lower end of the front fork part is matched with the front shaft part to form a guiding system of the bicycle. The front wheel can change direction by rotating the handle bar and the front fork, thereby playing a guiding role of the bicycle. The front fork member is stressed by the cantilever arms Liang Xingzhi, so the front fork member must have sufficient strength and the like.

5. And (3) a chain: the chain is also called a car chain and a roller chain and is connected with the chain wheel and the flywheel. The pedal force is transmitted to the flywheel and the rear wheel by the crank and the chain wheel to drive the rear wheel of the bicycle to rotate, so that power is provided for advancing.

6. A sprocket: the pedal force is transmitted to the chain by the crank and is made of high-strength steel, so that the required pulling force is ensured.

7. Flywheel: the flywheel is screwed and fixed at the right end of the rear axle through internal threads, keeps the same plane with the chain wheel, and is connected with the chain wheel through a chain to form a driving system of the bicycle. The structure of the flywheel can be divided into a single-stage flywheel and a multi-stage flywheel. The single-stage flywheel is also called as single-sprocket flywheel and mainly consists of parts such as a jacket, a flat baffle, a core, a jack spring, a gasket, a wire baffle steel ball and the like.

8. Folding bicycle joint (folder)

The folding joint is the most critical part of the folding vehicle and bears the pressure from all aspects, so the folding joint is required to be very firm, and the folding joint is easy to operate and has artistic appearance.

At present, the existing folding bicycle or the folding electric bicycle adopts a folder which generally comprises two folding plates or folding plates, a locking mechanism, a hinge and the like which are respectively connected with a front fork and a rear frame, when the folding bicycle or the folding electric bicycle needs to be locked, the two folding plates are required to be attached to each other, the locking mechanism is sleeved into grooves for locking of the two folding plates, the length of the period of adjustment is carried out through threads of the locking mechanism, and finally, the folding bicycle is locked by closing a handle of the locking mechanism, so that the locking method is troublesome, and the folding process of the folding bicycle is complicated.
