The specific implementation mode is as follows:
the invention is further described below with reference to the accompanying drawings:
as shown in fig. 1 to 6, a brake device is mounted on a fork 23, and the brake device mainly includes a pedal fixing block 4, a pedal 1, a pull plate 2, a pedal pin 5, a pull plate pin 3, a brake rope 7, a first guide sleeve 8, a spring 9, a brake pad fixing block 6, a brake pad 10, a brake pad pin 11, and a second guide sleeve 12.
The pedal fixing block 4 is arranged on the upper portion of the fork 23 through a bolt and nut pair, a pin shaft hole is formed in the pedal fixing block 4, the pedal 1 is arranged through a pedal pin shaft 5, the pulling plate 2 is arranged through a pulling plate pin shaft 3, the brake rope 7 is fixedly arranged on the lower portion of the pulling plate 2, and the brake rope 7 is connected to the end portion of the brake pad 10 through a first guide sleeve 8 and a spring 9. The first guide sleeve 8 is arranged on the brake pad fixing block 6 through a bolt and nut pair. The joint part of the brake pad 10 and the wheel hub 2201 is arc-shaped, a second guide sleeve 12 is arranged at the part of the end part of the brake pad 10, which is connected with the brake rope 7, and a spring 9 is arranged in the second guide sleeve 12. The brake block 10 is installed on the brake block fixing block 6 through the brake block pin shaft 11, and the brake block fixing block 6 is fixedly installed on the fork 23 through a bolt and nut pair. The front end of the pedal 1 is provided with a right-angle bending structure, the tail end of the bending structure is provided with an arc-shaped rounded corner structure, and the free end of the pull plate 2 is also provided with a right-angle bending structure.
The operation principle is as follows: when braking is needed, a user steps down the pedal 1 downwards by feet, the pedal 1 rotates around the pedal pin shaft 5, the pulling plate 2 is driven to rotate around the pulling plate pin shaft 3 and lift upwards, the pulling plate 2 drives the brake rope 7 to lift upwards, the brake rope 7 drives the brake pad 10 to rotate around the brake pad pin shaft 11, the arc part of the brake pad 10 is driven to lean against the wheel hub 2201, and braking is conducted through friction force. When the brake block 10 is in a reliable braking state, the outer side surface of the right-angle bending structure at the tail end of the pedal 1 is just attached to the lower side surface of the pull plate 2, so that the pedal and the pull plate are in a vertical locking state. The locking state ensures the braking state of the brake pad to be reliable. Meanwhile, the tail end of the right-angle bending structure at the tail end of the pedal 1 props against the inner side of the right-angle bending structure at the free end of the pulling plate 2, and the pedal 1 is stopped and limited.
When the brake is not needed, the pedal 1 is lifted upwards by feet, the vertical locking state of the pedal 1 and the pull plate 2 is unlocked, the pull plate 2 is loosened, the pull plate 2 is pulled by the brake rope 7 under the action of the spring 9 to fall down, and the pull plate drives the pedal 1 to rebound, lift and reset. Meanwhile, the brake pad 10 rotates around the brake pad pin 11 under the pushing of the spring 9, the wheel hub 2201 is loosened, and the braking state is released.
In the braking state, the spring is in a compressed state.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
