Abstract

The invention discloses a wheelchair brake assisting device which comprises a shell. A pair of cover plates, wherein the cover plates are detachably arranged on the two end surfaces of the shell; a locking assembly is detachably arranged in the shell, and the locking assembly comprises a pair of racks which can rotate relative to each other; a positioning assembly is arranged between the racks in a sliding manner; wherein the locking assembly is located between a locking position and an unlocking position, when the locking assembly is located at the locking position, the positioning assembly is locked, and when the locking assembly is located at the unlocking position, the positioning assembly can freely slide. Due to the fact that the wheelchair brake is of a separated structure, the wheelchair brake is particularly suitable for modification of a common wheelchair, and the common wheelchair can also enjoy the brake keeping function.
