Embodiment 1

[0040] See figure 1 with figure 2 , The multifunctional frame in this embodiment includes a rear tripod -1, a front tripod -2, and a bottom bracket connecting rod 1-3. There is a fixed hinge point between the front tripod 1 and the rear tripod 1, and the bottom bracket is connected The middle end of the rod one is fixed and hinged with the front tripod one, and the rear end is slidingly hinged with the rear tripod. There is a lock at the hinge point. The rear tripod one, the front tripod one and the central axis connecting rod one A crank slider mechanism is formed, and the wheelbase of the wheel axles connected between the front and rear workshops can be changed by turning the angle between the front tripod one and the rear tripod one.

[0041] The specific description will be given below in conjunction with the bicycle equipped with the frame. See also figure 1 with figure 2 , The bicycle in the figure includes the rear tripod 1, the front tripod 2, the bottom bracket link 3,...

Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is that the bicycle transmission mechanism in this embodiment adopts an exposed form. See for details image 3 with Figure 4 Similarly, a crank mechanism is set at the front end of the bottom connecting rod-3, the middle section is fixed and hinged with the front tripod -2, and the rear end is slidingly hinged with the rear tripod -1. Among them, the axis 24 and the sliding hinge point are provided in the crank mechanism. Between the five shafts 26 of the bicycle, and between the shaft five 26 and the shaft one 21 of the rear wheel, two chain mechanisms are used to drive, in which the crank mechanism is connected to the gear plate, the rear wheel of the bicycle is equipped with a flywheel, and the chain guide with tension function , It can also tension the chain due to the change in length when changing the bicycle riding mode.

Embodiment 3

[0054] The rigid tripods used in both the front and rear frames in embodiment 1 and embodiment 2. In this embodiment, on the basis of embodiment 1 and embodiment 2, a rigid tripod is used for the front frame and a flexible tripod is used for the rear frame. Suspension frame, specifically as Figure 5 with Image 6 As shown, the shock-absorbing frame is formed by hingedly connecting a rigid rear tripod 31 with a middle rod 32 and a shock absorber 35 to form an elastic tripod. The elastic tripod, another rigid tripod and the central axle connecting rod form an integral tripod body of the bicycle frame, and the shock-absorbing performance of the frame improves the comfort of the bicycle passing on uneven roads.

[0055] The following is a specific description in conjunction with the bicycle equipped with the above frame, and refer to Figure 5 with Image 6 , Bicycle rear tripod two 31, middle rod 32, front tripod two 33, bottom axle connecting rod two 34, shock absorber 35, front fo...

Abstract

The invention discloses a multifunctional frame, a bicycle and a work method of the bicycle. A front frame body, a rear frame body and a center shaft connecting rod of the bicycle frame are hinged in the same plane through a slider-crank mechanism or four-bar mechanism, and rotating adjustment of the triangular bicycle frame is achieved. A two-segment type transmission mechanism is correspondingly adopted, corresponding adjustment of shape transformation of the front frame body and the rear frame body is achieved, two postures of normal sitting riding and lying riding can be achieved, and transformation between a normal bicycle and a lying bicycle is achieved. The multifunctional frame and the bicycle are simple in structure, one bicycle has the two forms of normal sitting riding and lying riding, the bicycle frame is convenient to transform and reliable in structure, the functionality of the bicycle is improved, the bicycle cost is reduced for a rider, the riding interest of people can be increased, and low-carbon travels by the bicycle can be popularized.

Description

Technical field [0001] The invention relates to a multifunctional frame, a bicycle and a working method thereof. Background technique [0002] With the call for low-carbon travel, people are paying more and more attention to bicycle riding. The current bicycles have a variety of functions, such as mountain bikes or road bikes for competitive exercise, recreational vehicles for daily riding, and convenient transfer and carrying. Folding bicycles can be divided into seated bicycles and lying bicycles according to the riding posture. Recumbent bicycles refer to the rider who can lean on the bicycle seat cushion and pedal forward with his feet. The way of lying down riding allows riders to ride in a comfortable way, which has attracted more and more attention from riders. [0003] The above types of bicycles only have a single riding position. If the cyclist needs to configure bicycles with different functions for different riding purposes, especially the cost and price of special lyi...
