Description
Technical field
The utility model belongs to a kind of folding pedal plate on folded bicycle, more particularly to a kind of with buffer unit
Folding pedal plate.
Background technology
China Patent No. 201611067602.4 is a kind of folding pedal plate of the applicant's patent application, although the folding
Foot pedal be the folding with vehicle frame and auto-folder and with vehicle frame expansion and Automatic-expanding, and fold and opened
Journey is convenient and efficient, and folding mode is simple to operation, and overall vehicle is more compact after folding, volume smaller, easily portable, but the folding
There is also following defects for folded foot pedal：Since the foot pedal auto-folder of folding pedal plate is by foot pedal auto-folder
Foot pedal in the connecting shaft of front frame middle and upper part is sleeved on device to open the transmission of rotatable key, drive foot pedal automatic folding device
The rack that is fixedly connected below upper connecting rod and two gear engagement rotations on the inside of rack and two foot pedals by, realizes foot
Auto-folder and Automatic-expanding are stepped on, but since the rack below the pull rod and pull rod on foot pedal automatic folding device is solid
Surely the structure that connects, there is no the buffer units for being equipped with gear and rack engagement rotation, therefore when the folded vehicle of expansion is stopped
Roadside accidentally or do not overturn or turn over easily come to another side when, the foot pedal of unfolded state encounters ground or by hard
Object impact or while artificially pulling foot pedal upwards easily cause gear on Folding pedal panel assembly and rack it is stuck and
Damage, to cause folding pedal plate damage can not auto-folder.
Utility model content
The purpose of this utility model be for unfolded state in the prior art foot pedal accidentally run into ground or by

The foot pedal that is sleeved in connecting shaft 2 opens rotatable key 6 and rotates down simultaneously, and chain piece I 8 and chain piece 119 loosen, foot pedal from
Rack 16 below the dynamic lower pull rod of elastic force heap of folding pressure spring 15 in dynamic folding device will move the left and right sides by heap downwards
Two 17 engagement rotations of gear, two foot pedals 4 are folded up in the both sides (as shown in Figure 5) of front frame 1, ride at this time automatically
Plate auto-folder buffer unit 3 does not work, and overall vehicle is more compact after folding, volume smaller, easily portable；When vehicle frame is unfolded
When, cushion vehicle frame 5 opens up, and the connecting shaft 2 of cushion vehicle frame front end drives the foot pedal being mounted in connecting shaft 2 to open rotation
Rotatable key engaging lug 7 on key 6 is rotated up, and drives chain piece I 8, chain piece II 9 upward, pull pull rod 14 and rack 16 to
On, while two 17 engagement rotations of gear, two foot pedals 4 of two 4 insides of foot pedal being driven to automatically open in front frame 1
Both sides (as shown in Figure 1, Figure 2 and Figure 4), at this time foot pedal auto-folder buffer unit 3 also do not work；Only when the folding of expansion
Vehicle parking roadside accidentally or do not overturn or turn over easily come to another side when, unfolded state foot pedal 4 encounter ground or
It being impacted by hard object or artificially pulls foot pedal upwards, foot pedal auto-folder buffer unit 3 is just started to work, due to
Foot pedal 4 is encountered ground or hard object and is drawn with 16 engagement rotation of rack by the gear 17 of the left and right sides two of impact foot pedal 4
Carry-over bar 16 is downward, and the buffer spring 22 of the foot pedal auto-folder buffer unit 3 of 16 epimere of rack setting compresses (such as Fig. 6 institutes
Show), thus gear 17 and 16 engagement rotation of rack will not stuck and damage, reach buffering and protection gear 17 and 16 mesh of rack
's.
