Title:
HELMET SHIELD LIFTING MECHANISM AND VARIABLE CHIN GUARD HELMET CONFIGURED WITH LIFTING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/033694
Kind Code:
A1
Abstract:
Disclosed is a helmet shield lifting mechanism. By means of a structural layout and operation mode of arranging a first restraining rail (3b) and a second restraining rail (3c) on a leg (3a) of a shield (3) and providing a drive element (4), in an auxiliary manner, to come into contact with and drive same, a lifting action of the shield (3) with respect to a helmet body (1) and a process thereof become forced and controllable modes, and thus being able to improve the working reliability and flexibility of the shield lifting mechanism, and also being able to smoothly open the shield (3) without an impact and to thus improve the wearing comfort of the helmet. Furthermore, a variable chin guard helmet configured with the helmet shield lifting mechanism can flexibly plan the lifting process of the shield (3) so as to adapt to different operation position states of a chin guard (2), thus greatly reducing the probability of the chin guard (2) colliding with the shield (3). A gear restraining mechanism is used to complete the transition of the chin guard (2) between a full-helmet structure position and a half-helmet structure position, thus improving the transition accuracy and reliability of the variable chin guard helmet.
