Description

M243420 创作, Creation Instructions (1) [Technical Field] This creation is aimed at those who have fixed the body type. [The previous technology is based on the structure developed by many automatic methods and the space developed by the former. The desired folding is based on the structure of the car. [Content] It is a suspension frame for a bicycle. A new bicycle frame folding structure made of only a folding frame, an inclined bracket, a rear frame and a shock absorber. The specially structured special storage structure space is designed to achieve the self-folding of the bicycle frame. Therefore, when the industry structure is designed, the volume reduction structure designed by this creation has the structure of the already developed car structure. Even if the realm introduces the new ones to be revealed by the existing facilities, it can only fold out many models. The new type meter has been designed before, that is, the design of the type folding carrying or receiving, this is all endlessly used for all existing frame types can not be applied is for the purpose of a stack of constructors, Because the folding works are the same in the industry, the designers are more rational about the various folding states of the used shelves. A specific technical problem to be solved on its own: especially for a novel folding structure space provided by a specific bicycle suspension frame type composed of an upper cross frame, a ^ frame: a rear frame and a shock absorber Type person.廿 Technical characteristics for solving the problem: The frame of the bicycle mainly includes a horizontal frame, an inclined support, a rear frame and a shock absorber; a front seat tube is provided at the upper end for the front rod assembly, and a rear end There is a rear seat with two tees to seat the tube inserting group; the top of the inclined bracket is fixed on the bottom side of the upper cross frame, and the bottom two shells are 1

The rear frame (3 0) will only exist with the pivot group state of the transverse axle tube (21), constituting the rear end of which can be swung vertically. In this state, the user can use the rear frame (3 0). After the end is folded toward the front of the vehicle, the purpose of reducing the volume of the frame is achieved. [Effect description] The fact that the effect of this creation is enhanced is as follows: This creation is aimed at a specific composition composed of an upper horizontal frame (10), an inclined support (20), a rear car wood (30), and a suspension (40). The bicycle frame body (generally called the five-way pipe), designed a folding structure suitable for this type of frame. According to the foregoing description, only one end of the shock absorber (4 〇) is required for folding in this creation. The latch (41) can be pulled out to perform the folding action of the rear frame (30). Not only is the operation quite simple, convenient and progressive, but also the structure of the pivot group of the rear frame (30) is improved, and the structure is also quite equivalent. It is simple and conducive to mass production and production, which is in line with better industrial applicability. On the other hand, the rear end of the rear frame (30) can be convex with the tube section (2 2) as the pivot pivot pivoting feature. , The telescopic shock-absorbing action of the shock absorber (40) will be particularly smooth, and those who obtain a better shock-absorbing buffer effect.
