Problems solved by technology

[0004] Compared with the device for synchronously reducing the width of bicycles, the patent application No. PCT / CN2008 / 073824 discloses a device for disassembling pedals, which is too complicated to be commercialized
[0005] Similarly, for the control folding crank mechanism of the utility model patent CN201376647Y authorized by China, the strength of the folding crank itself is a problem; at the same time, because the crank block connected to the pedal is driven to rotate with a large transmission ratio through the transmission mechanism, it will make the crank block rotate. The moving mechanism bears a large force, which is not conducive to operation and implementation

Embodiment 2

[0093] refer to Figure 8 to Figure 11 , in this embodiment, the pedal blocks 11b with the first grooves 21b at both ends are connected to the connecting block 22b by screws to form an integral folding pedal, which is convenient for assembly; one of the pedal blocks is connected to a Part of the toothed gear 24b is fixed, and the other pedal block is protruded with a protrusion 25b that assists the folded pedal to return to fold. Two lock blocks 26b are fixed on the brake ring 15b, one end of the lock block can be matched with the first groove 21b of the pedal block 11b, and the other end can be matched with the second groove 27b of the pedal body 3b. A rack 28b and a top block 29b are respectively fixed on each of the locking blocks, and a limit protrusion 33b protrudes from the edge of the pedal body 3b to make the rack 28b and the top block 29b move oriented. Among them, the rack 28b cooperates with a gear 24b fixed on the pedal block to rotate the pedal block 11b, and the...

Embodiment 3

[0106] refer to Figure 12 and Figure 13, the pedal body 1c is connected to the crank 2c through an axis fixed to the crank 2c, two pedal blocks 11c are respectively hinged on the pedal body on both sides of the pedal body, and the pedal body and the pedal blocks have respectively limited structures 16c, 17c, The pedal block can only rotate in one direction relative to the pedal body, and the rotation directions of the two pedal blocks are just opposite. Simultaneously, each independent pedal block realizes dislocation cooperation through the dislocation of its own hinge hole and the gap of the hinge shaft 14c and the gap of a gear 12c on one side, and the purpose is to fix the gear on one side with one of the pedal blocks. At the same time, there are two brake racks 13c meshing with the gears on both sides of the pedal body. One end of the brake racks 13c forms a groove 18c that can accommodate the brake ring 15c. There are also friction-reducing balls inside the groove. ....

Embodiment 4

[0112] refer to Figures 14 to 16 , The pedal block 5d and the pedal block 6d are respectively hinged to both sides of the pedal body 1d through two hinge shafts 33d. Simultaneously, the inner side of the pedal block 5d has two stop position inner flanges 50d, and the inner side of the pedal block 6d also has two stop position inner flanges 60d. When the two pedal blocks are not folded, the stop position end 55d of the pedal body 8d Located in the middle of the inner flanges of the two pedal blocks, like this, the rotation of the two pedal blocks toward the folding direction is restricted.

[0113] In addition, the brake bar 71d is hinged to the pedal block 5d through the connecting rod 61d, and the brake bar 72d is hinged to the pedal block 6d through the connecting rod 62d. The two brake bars are fixed to the same brake ring 15d, so that the two brake bars The bars can move synchronously; in this way, the links 61d and 62d are indirectly hinged to the brake ring 15d via the...

Abstract

The invention discloses a device for controlling the synchronous folding of folding pedals on both sides of a bicycle. The pedal body is rotatably connected, the pedal body has a first rotation axis, the folding pedal has a second rotation axis, the folding pedal has a working position and a folding position on its rotation track, and the brake ring has a The degree of freedom of reciprocating movement of the first rotation axis, the braking ring drives the folding pedal to switch between the working position and the folding position through the folding transmission mechanism. When folding, the brake ring is driven to fold the pedal, which is easy to operate, and the hand does not need to directly touch the pedal during the folding process.

Description

technical field [0001] The invention relates to a device for synchronously folding foldable pedals on both sides of a bicycle. Background technique [0002] Bicycle is one of the most popular means of transportation. Due to the increasing number of bicycles and the larger size of the bicycle frame, bicycle parking takes up more space, and bicycle pedals will bring unnecessary width when bicycles are parked. Therefore, at present More folding pedals are used on the market. [0003] Folding pedals achieve the folding effect by turning over the pedals. This kind of pedal folding requires direct contact with hands, which will dirty hands. Simultaneously, because the horizontal height of folding pedal is relatively low and is distributed on both sides of bicycle frame. Therefore, the folding pedal not only brings troubles to the user's operation but also soils the user's hands. [0004] Compared with the device for synchronously reducing the width of bicycles, the patent appli...
