Refer to Fig. 1-Figure 14
The fold mechanism that present embodiment provides, comprises supporting component, rotary components and limit assembly; Rotary components comprises outward turning turntable 201, interior revolving part 202 and attaching parts 203, it is outside and be rotationally connected with attaching parts 203 that outward turning turntable 201 and interior revolving part 202 are all set in attaching parts 203, and outward turning turntable 201 has at least two pieces and is symmetrically distributed in the left and right sides of interior revolving part 202; Supporting component comprises the first strut member be arranged in outward turning turntable 201 and the second strut member be arranged on interior revolving part 202; Limit assembly comprises locating dowel pin 204 and position-limited trough 205, and position-limited trough 205 has at least two, all position-limited troughs 205 along the axis annular spread of rotary components on rotary components; After locating dowel pin 204 inserts position-limited trough 205, outward turning turntable 201 and interior revolving part 202 can not produce relative rotation.
This fold mechanism is applied to other non-power-driven vehicles such as bicycle or battery-driven car.Supporting component is used for supporting each parts, and rotary components and limit assembly are the main working parts of fold mechanism; Outward turning turntable 201 and interior revolving part 202 are all arranged on the outside of attaching parts 203, all can rotate by opposite joints 203, when rotational angle is inconsistent on attaching parts 203 for outward turning turntable 201 and interior revolving part 202, can produce relative rotation therebetween.
After the locating dowel pin 204 of limit assembly inserts position-limited trough 205, outward turning turntable 201 and interior revolving part 202 can not produce relative rotation, and now this fold mechanism is locking state; After locating dowel pin 204 is separated with position-limited trough 205, can produce relative rotation between outward turning turntable 201 and interior revolving part 202.
When producing relative rotation between outward turning turntable 201 and interior revolving part 202, drive the first strut member and the second strut member to rotate around the axis of attaching parts 203, the angle between the first strut member and the second strut member is changed, completes folding work.
When position-limited trough 205 has two, two kinds of different angles can be produced between first strut member and the second strut member, when between the first strut member and the second strut member, angle is less, fold mechanism is folded state, when between the first strut member and the second strut member, angle is larger, fold mechanism is open mode.
Position-limited trough 205 also can be other numbers.Be preferably two.
This fold mechanism structure is simple, easy to use, can carry out folding fast and organize work.
Present embodiment additionally provides a kind of folded bicycle, comprises handle, wheel, vehicle seat and above-mentioned fold mechanism, and the first strut member on fold mechanism comprises pipe 211 and back vent 214, second strut member comprises a pipe 213 and lower pipe 212; Wheel comprises front-wheel and trailing wheel, and vehicle seat is located on a pipe 213, and front-wheel is located on lower pipe 212, and handle is located on pipe 211, and trailing wheel is located on back vent 214.
As shown in figure 12, apply the folded bicycle of fold mechanism, time folding, upper pipe 211 and back vent 214 produce relative rotation with seat pipe 213 and lower pipe 212, and the structure of folded bicycle can be made to diminish.
The effect of locating dowel pin 204 and position-limited trough 205 is that restriction rotating mechanism rotates, and when locating dowel pin 204 and position-limited trough 205 coordinate, outward turning turntable 201 and interior revolving part 202 can not produce relative rotation.Therefore locating dowel pin 204 and position-limited trough 205 need to be separately positioned on outward turning turntable 201 and interior revolving part 202.

Be arranged on interior revolving part 202 for locating dowel pin 204 below and launch.
Preferably, locating dowel pin 204 is connected with pull bar 206, and one end of this pull bar 206 is extended interior revolving part 202 and formed operating portion.Locating dowel pin 204 can be operated easily by this operating portion, make it coordinate with position-limited trough 205 or be separated.
The operating portion of pull bar 206 can be extend the outside that interior revolving part 202 is positioned at revolving part 202; Preferably, operating portion is located in the second strut member, and the end of operating portion is connected with handle 207, and this handle 207 extends the second strut member.
As shown in the figure, moving handle 207 can drive pull bar 206 to move, and then drives locating dowel pin 204 to move.This design makes locating dowel pin 204 and pull bar 206 be not easy to be subject to the impact of miscellaneous part, makes locating dowel pin 204 can complete spacing work better.
Preferably, locating dowel pin 204 is bar shaped, and its length direction is parallel with the axis direction of interior revolving part 202; Second strut member is provided with U-shaped through hole 208, and the length direction of this U-shaped through hole 208 is vertical with the axis direction of interior revolving part 202.
As shown in Fig. 1 or Fig. 7, pull handle 207 along the direction away from interior revolving part 202, drive locating dowel pin 204 to move, locating dowel pin 204 can be made to be separated with position-limited trough 205.
Preferably, pull bar 206 is provided with limit spring 209, after locating dowel pin 204 is separated with position-limited trough 205, spring is in compressive state.The design of limit spring 209 makes locating dowel pin 204 have automatic reset function; Pulling during handle 207 to make locating dowel pin 204 be separated with position-limited trough 205, and by the elastic force effect of limit spring 209 after release handle 207, locating dowel pin 204 resets.
Attaching parts 203 is preferably cylindrical shape, and the two ends, left and right of attaching parts 203 sidepiece are provided with the groove 210 for installing outward turning turntable 201.
The design of groove 210 makes outward turning turntable 201 can firmly be arranged on attaching parts 203.After outward turning turntable 201 is installed on attaching parts 203, set up block piece in the end of attaching parts 203, can guarantee that outward turning turntable 201 can not drop from attaching parts 203.
Further, interior revolving part 202 comprises two pieces of semicircular structure parts removably connected.This design makes interior revolving part 202 easy to process, and can be installed to easily on attaching parts 203.Two pieces of semicircular structure parts connect preferably by bolt, make stable connection therebetween.The direction of bolt is preferably vertical with the axis direction of interior revolving part 202, makes assembling more convenient.
The folded bicycle applying above-mentioned shockproof mechanism has good folder function, folding very convenient.Preferably, this folded bicycle also comprises shockproof mechanism, and this shockproof mechanism comprises front pipe 101, and upper pipe 211 is slidably connected on front pipe 101 by upper node 102, lower pipe 212 is fixed on front pipe 101 by lower node 103, is provided with shock-proof spring between upper node 102 and lower node 103.
Vehicle easily causes vibrations by factors such as Uneven roads in the process of moving, and vibrations can be offset by shockproof mechanism preferably, and vehicle is moved ahead reposefully.Shockproof mechanism realizes mainly through shock-proof spring, when vehicle vibration, and upper node 102 slide downward, compression shock-proof spring; After vibroseis disappears, shock-proof spring resilience, in drive, node 102 playbacks, and completes shock-absorbing by this process.In addition, fold mechanism coordinates shockproof mechanism to use, and vehicle is when folding, and upper node 102, along sliding on front pipe 101, enables folding work carry out smoothly.
Particularly, handle is located at the upper end of front pipe 101, and front-wheel is located at the lower end of front pipe 101.The direction of front-wheel can be regulated by handle.
