Abstract
An electronic deadbolt lock which includes a housing; an electronic recognition device disposed on the housing; a turnpiece pivotally mounted on the housing and connected to a deadbolt; a key operating mechanism disposed on the housing and connected to the deadbolt, wherein the deadbolt moves as a result of rotation of one of the turnpiece and the key operating mechanism; and a braking mechanism controlled by the electronic recognition device, wherein the braking mechanism normally applies a brake to the turnpiece to prevent the turnpiece from being rotated, and it is only when a user passes verification by the electronic recognition device that the turnpiece can be rotated by the user.

An electronic deadbolt lock, comprising:
- a housing;
- an electronic recognition device disposed on the housing;
- a turnpiece pivotally mounted on the housing and connected to a deadbolt;
- a key operating mechanism disposed on the housing and connected to the deadbolt, wherein the deadbolt moves as a result of rotation of one of the turnpiece and the key operating mechanism;
- and
- a braking mechanism controlled by the electronic recognition device,
- wherein the braking mechanism normally applies a brake to the turnpiece to prevent the turnpiece from being rotated, and it is only when a user passes verification by the electronic recognition device that the turnpiece can be rotated by the user;
- wherein the turnpiece comprises:
- a rotating body connected to the deadbolt;
- and
- a rotating cover connecting with and covering the rotating body, wherein the rotating cover and the rotating body either rotate synchronously or do not rotate synchronously;
