Abstract

The embodiment of the invention discloses a backstop, a motor device, a curtain control device and an electric curtain. The backstop includes: a driving force receiving part; a control part arranged on one side of the driving force receiving part; a fixing sleeve arranged on the outer side of the control part in a sleeving mode, wherein a first non-return face is arranged on the side, away from the driving force receiving part, of the fixing sleeve; and a driving force output part which is arranged on the side away from the driving force receiving part in the mode of being matched with the control part, and is provided with a second non-return surface which is elastically controlled; the second non-return surface is in an elastic stretching state, and the first non-return surface is matched with the second non-return surface in a non-return manner; and when the driving force receiving part obtains torque, the control part is driven to cooperate with the driving force output part, so that the second non-return surface is in an elastic compression state, the second non-return surface is separated from the first non-return surface, and the driving force output part can rotate. Through the embodiment of the invention, the problems that an existing backstop is complex in structure and poor in durability are effectively solved.

Description

technical field [0001] The invention relates to the technical field of curtain control, in particular to a backstop, a motor device, a curtain control device and an electric curtain. Background technique [0002] As a basic component in mechatronic mechanical transmission, the backstop usually adopts a one-to-one matching arrangement of multiple needle rollers and multiple elastic parts to realize the backstop function. Existing electric curtains include opening and closing type curtains and roller blinds, wherein the roller blinds need a backstop to stop due to the gravity of the roller blinds, so as to prevent the roller blinds from sliding down automatically. [0003] However, the structure of the backstop, which adopts a one-to-one correspondence between a plurality of needle rollers and a plurality of elastic members to realize the backstop function, is complex, prone to failure, and poor in durability. Contents of the invention [0004] Therefore, the embodiment of ...
