Check link structure

摘要

A check link structure includes a first bracket, a cam arm and a cam follower. The first bracket has a pivot support structure defining a first pivot axis. The cam arm is coupled to the first bracket for pivotal movement about the first pivot axis. The cam arm includes a cam block and a support shell. The cam block has a cam surface that includes a plurality of positioning recesses and a plurality of movement restricting lobes between adjacent ones of the plurality of positioning recesses. The support shell defines a block receiving space that non-movably retains the cam block. The cam follower has a follower surface that is configured to continuously contact the cam surface of the cam block in response to movement of one of the first bracket and the cam follower relative to the other of the first bracket and the cam follower.

1. A check link structure comprising:
a first bracket having a pivot support structure defining a first pivot axis; a cam arm coupled to the first bracket for pivotal movement about the first pivot axis, the cam arm comprising:
a cam block made of a self-lubricating material, the cam block having a cam surface that includes a plurality of positioning recesses and a plurality of movement restricting lobes between adjacent ones of the plurality of positioning recesses; anda support shell defining a block receiving space that non-movably retains the cam block, the support shell including an upper plate, a lower plate, and a rear plate extending between the upper plate and the lower plate with the block receiving space defined between the upper plate and the lower plate, the upper plate covering the majority of an upper surface of the cam block, the lower plate covering the majority of a lower surface of the cam block, the rear plate covering substantially all of a rear surface of the cam block, and the cam surface extending past respective distal ends of the upper plate and the lower plate; and a cam follower having a follower surface that is configured to continuously contact the cam surface of the cam block in response to movement of one of the first bracket and the cam follower relative to the other of the first bracket and the cam follower.
