ENGAGEMENT ASSEMBLY, SLIDING RAIL MECHANISM HAVING SAME, DRAWER, REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2019/205674
Kind Code:
A1
Abstract:
An engagement assembly (100), a sliding rail mechanism (300) having same, a drawer (400), and a refrigerator. The engagement assembly (100) comprises a first engagement part (10) matching the drawer (400) and a second engagement part (20) matching a refrigerator body (500); one of the first and second engagement parts (10, 20) is a gear (10, 10', 10a, 10b), and the other one is a rack (20); the rack (20) has a tooth surface (21) that allows the gear (10) to travel; the rack (20) comprises a main rack (22, 22', 22a, 22b) and an extension rack (23, 23', 23a, 23b); when the drawer (400) is in a closed state, the tooth surface (21) has a first stroke length (L1); when the drawer (400) is in an opening process, the extension rack (23, 23', 23a, 23b) moves to a travel path of the gear (10) so that the tooth surface (21) has a second stroke length (L2); when the drawer (400) is in a closing process, the extension rack (23, 23', 23a, 23b) is reset; the first stroke length (L1) is smaller than the second stroke length (L2). The length of the tooth surface (21) of the rack (20) is variable, and the length of the tooth surface (21) increases in the opening process of the drawer (400) so that the distance which the drawer (400) may be pulled out increases; this facilitates a user accessing items in the drawer (400) and thus improves the user experience.
