DAMPED HINGE AND CONTROL DEVICE THEREOF
First Claim
1. A damped spring hinge, comprising:
- a shaft seat (1) having a seat body (11), the seat body having a shaft hole (12), a receiving hole (13), and an oil conduit (14) formed therein, the receiving hole being substantially normally arranged and in communication with the shaft hole, the oil conduit (14) connecting the shaft hole and the receiving hole at the opposite end portions thereof;
a shaft (2) rotatably disposed in the shaft hole of the seat body having a fixing surface (21) is formed on the middle portion thereof;
a sleeve (3) sealingly disposed in the opening of the receiving hole;
a sliding member (4) having a thru hole (41) formed on one end thereof slidably mated with the sleeve,wherein the thru hole end thereof abuts the fixing surface of the shaft,wherein the sliding member and the sleeve jointly defines an oil reservoir (42) for storing hydraulic oil;
an elastic unit (5) disposed in the oil reservoir between the sleeve and the sliding member;
a non-return valve (6) disposed in the oil reservoir between the thru hole end of the sliding member and the elastic member;
a throttle valve (7) extending into the conduit of the shaft seat for regulating oil flow in the oil conduit;
a first connecting member (8) fixedly coupled to the shaft seat; and
a second connecting member (9) rotatably coupled to the shaft.

Abstract
A damped spring hinge is disclosed, which includes a shaft seat, a shaft, a sleeve, a sliding member, an elastic unit, a non-return valve, a throttle valve. The shaft seat has a seat body, wherein a shaft hole and a receiving hole are formed in the seat body. The shaft can be rotatably disposed in the shaft hole. The sleeve is received in the receiving hole. The sliding member can be slidably disposed in the sleeve. An oil reservoir is formed by the sliding member and the sleeve. The elastic unit is disposed in between the sleeve and the sliding member. The non-return valve is disposed in the oil reservoir, and the throttle valve is disposed on the seat body. Thereby, a self-closing action for the door can be generated, along with the damping effect by the hydraulic oil. A control device of the damped spring hinge is also disclosed.
