Embodiment Construction

[0027] refer to Figure 1 to Figure 4 According to an embodiment of the door-mounted mechanism (for example: smart lock) of the present disclosure, it is applied to a smart lock system, and is suitable for being installed on a door (not shown) and used to turn a door lock knob (Thumb turn, FIG. not shown). The door lock includes a base plate (not shown) installed on the door, and the knob is rotatably disposed on the base plate. The door-mounted mechanism includes a housing 1 , a rotating member 2 , an actuating unit 3 and an intermediary coupling 4 .

[0028] The casing 1 includes a bottom wall 11 , and a surrounding wall 12 extending from the periphery of the bottom wall 11 and defining a receiving space together with the bottom wall 11 . In this embodiment, the bottom wall 11 is substantially square. The surrounding wall 12 has a door installation end 121 , and the accommodating space has an opening at the door installation end 121 , the opening allows the door lock to p...

Abstract

An angle of rotation sensor for measuring an angle of rotation of a rotatable object includes an electrically conductive band to be disposed onto the rotatable object and having two terminal ends which are spaced apart from each other and which are respectively applied with different voltages; an electrical brush in electrical contact with the electrically conductive band; and a voltage measuring device coupled to the electrical brush and measuring a divided voltage which is a voltage at a position of the electrically conductive band at which the electrical brush contacts. The angle of rotation of the rotatable object is associated with the divided voltage and the different voltages.

Description

[0001] Cross-references to related applications [0002] This application claims priority to U.S. Provisional Application Nos. 62 / 061,209, filed October 8, 2014, and U.S. Provisional Application Nos. 62 / 068,698, filed October 26, 2014. technical field [0003] The disclosure relates to a rotation angle sensor, a door mounting mechanism including the rotation angle sensor and a brush suitable for the rotation angle sensor, and in particular to a rotation angle sensor, a door mounting mechanism that saves calculation time and energy Mechanisms and brushes. Background technique [0004] Electronic security systems have been around for many years. In recent years, electronic technology has been combined with traditional door locks to introduce smart locks. The disadvantage of smart locks is that the existing door lock needs to be replaced during installation, and the installation process of smart locks is relatively complicated, requiring professional workers to use special to...
