Description

Improved generation body-building bicycle

Technical Field

The utility model relates to a bicycle, in particular to an improved body-building bicycle.

Background

The riding mode of the traditional bicycle basically uses the upper limbs, the lower limbs, the buttocks and the like of a person to be positioned at the respective positions for definite division of work, and is respectively used for controlling the direction, providing power, stabilizing the gravity center of the body and the like. In contrast, the utility model patent (name: pulling and pedaling recoil bicycle, patent number: 201110287532.4) and the utility model patent (name: novel exercise bicycle, patent number: 201720859093.2) disclosed by the inventor are reciprocating riding bicycles with coordinated whole body of upper limbs, lower limbs, waist and back and the like, and the technology accords with the basic principle of operation of the centrifugal force and centripetal force of the bicycle in opposite unified balance. The main structural characteristics and the using mode of the vehicle are as follows: firstly, the design and the use of the frame of the bicycle are obviously different from those of the traditional bicycle, and a sliding seat is arranged on the upper side of a sliding rail beam of the bicycle frame assembly and can slide back and forth on the sliding rail beam; secondly, the handle bar and the pull rod have two functions, namely a power rod and a direction rod, and can move back and forth when the power rod is used and can rotate left and right when the direction rod is used, and the two actions do not interfere with each other; again, the foot pedals are stationary and are mounted relatively forward of the left and right sides of the frame. The riding mode of the bicycle is as follows: when the two arms of a person pull the handle bar backwards and force the two legs to pedal at the pedal, the buttocks slide along the sliding seat along the sliding rail beam backwards, the lower limbs, the trunk and the arm parts of the human body are gradually stretched, at the moment, the pull rod moves backwards, the arm part at the lower end of the center shaft hinge drives the traction chain forwards, then drives the flywheel to rotate, and the bicycle starts to move forwards. When arms and legs of a person basically extend and the sliding seat slides up to the rear part of the bicycle to be folded back, buttocks return to the front part of the bicycle along with the sliding seat, then the arms, the lower limbs, the trunk and the like of the human body repeat the next action, and the action is performed in a reciprocating way, so that the bicycle continuously moves forward. The whole body movement mode is basically similar to the international olympic and European and American water racing boat movement, not only can exercise about eighty-five percent of muscles of the human body, but also can strengthen the coordination of the whole body.

The design of the bicycle frame assembly is the basis of the whole bicycle, and determines the quality, the function and the safe normal use of the bicycle, so that the structural design is very critical. In the design of the frame, the slide rail beam structure of the frame adopts a design mode of low front and high rear straight lines, and meets the basic requirements of human engineering, but the structure still has three basic defects: 1. according to the analysis of the ball rolling principle of the slope track, a ball downward rolling experiment is carried out on the linear slide rail and the arc slide rail, and the result shows that the sliding effect of the linear slide rail in the prior art on the sliding seat is not the best design, because the sliding speed of the ball is not the fastest although the distance between the two ends of the linear slide rail is shorter than the distance between the two ends of the arc slide rail; 2. when a person moves backwards along with the sliding seat during riding, negative force is generated opposite to the forward direction of the bicycle, so that the riding speed of the bicycle is influenced; when a person moves forwards along with the sliding seat, forward positive force is generated due to inertia, so that impact is brought to a relatively balanced vehicle and the person, unbalance is aggravated, and the safety is not guaranteed; 3. in the riding process, people pull the pedals by hands to exert force on the whole body and move backwards along with the sliding seat, when unexpected faults of the power structure occur in the process, such as chain breakage or disengagement, under the action of inertia gravity, the human body can slide to the rear tail part of the vehicle along the linear sliding rail along with the sliding seat, so that the human body and the vehicle are overturned together, and the problem is very dangerous. The inventor has a profound experience on the defects in the riding process, and particularly has two relatively serious rollover and wrestling accidents; 4. the supporting seat which is positioned below the side of the frame and at the rear side of the front wheel and used for tensioning the chain is a rigid rod, and the supporting wheel at the lower end of the supporting seat frequently collides with an obstacle on the road surface in the riding process, so that the bicycle chain is suddenly stopped when the bicycle is out of function, the supporting wheel is damaged, and accidents are seriously caused; 5. the top of the framework of the sliding seat adopts a plane structure, and the framework is wrapped with a foam cushion, so that the sliding seat and the buttocks of a rider move forwards or backwards together, and the buttocks and the sliding seat often slip, so that the structure of the sliding seat needs to be improved.

Theoretical principle demonstration and a large number of practices prove that the structure of the linear sliding rail cross beam adopted by the frame in the two patent technologies must be improved and optimized so as to avoid the five basic defects.

Disclosure of Invention
