Specific embodiment

In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.

Fig. 1 illustrates a kind of a kind of embodiment of the folding mechanism of stroller of the utility model, including push rod 1, preceding Handrail 2, seat stay 3, front-wheel support 4, rear wheel support 5, backing tube 6 and bench hassock tube 7,

The preceding handrail 2 is equipped with the seat cushion sliding sleeve 8 of rotation, and the bench hassock tube 7 is slidably arranged in seat cushion sliding sleeve 8,

It is rotatablely connected between the front-wheel support 4 and rear wheel support 5 by the pipe 9 that returns the vehicle to the garage and knock off；

Iron plate A10 is interlocked equipped with backrest and backrest interlocks iron plate B11, and the backrest interlocks the one end iron plate A10 and connects seat cushion On pipe 7, the other end connects backing tube 6, and backrest interlocks the one end iron plate B11 connection backrest and interlocks mono- tie point of iron plate A11, and backrest connects The dynamic iron plate B11 other end connects one tie point of side lever, to reach the structure that backrest travels forward automatically when cart converts into；

Equipped with equivalent iron plate A12 and equivalent iron plate B13, at the equivalent iron plate B13 connection rear wheel support 5 a bit, convert into Iron plate A12 is connect with equivalent iron plate B13, is converted into a little 3 one points of seat stay of connection in iron plate A12, is converted into the connection of the one end iron plate B13 7 one points of bench hassock tube；To reach the structure of vehicle frame support locking.

The junction of the push rod 1 and preceding handrail 2 is equipped with electric bell joint A14 and electric bell joint B15, the push rod 1 with It is rotatablely connected between preceding handrail 2 by electric bell joint A14, one end of the electric bell joint B15 is rotatablely connected push rod 1, another End is rotatablely connected by after-poppet set 16 with seat stay 3.

The lower end of the seat stay 3 and the pipe 9 that returns the vehicle to the garage and knock off are rotatablely connected by equivalent movement iron plate 17, and the pipe 9 that returns the vehicle to the garage and knock off is with before Wheel support 4 is rotatablely connected by the iron plate 18 that returns the vehicle to the garage and knock off.

Its structural principle is as follows: being moved downward during ride is equivalent by after-poppet pipe 5 and interlocks equivalent iron plate A12 and folding Iron plate B13 is closed to move together downwards with bench hassock tube 7；Since preceding handrail 2 moves downward during (such as Fig. 2-4) is equivalent simultaneously, So that backrest is interlocked iron plate B11 pulls backrest gearing iron plate A to move forward with backing tube 6；Minimum, backrest is folded into reach vehicle The equivalent system authority moved forward simultaneously.
