## Abstract

A movable spoiler device is provided. The movable spoiler device includes: a fixed part, fixed on a body of a vehicle; a movable part, movable between a storage position and a deployed position; an actuator, disposed on the fixed part and drives the movable part to move in a front-rear direction; a rotating frame, connected to the actuator and rotates synchronously with the actuator; a connecting member, connected to the rotating frame and the movable part; and a locking member, disposed between the actuator and the rotating frame, applies force to the actuator through an elastic member, and is locked on the rotating frame, wherein, when the movable part is in the deployed position and is subjected to a load applied from the rear, the rotating frame is rotated by pushing the locking member against the elastic member to release the fitting of the locking member.

## Claims

### Claim 1

A movable spoiler device, comprising:
a fixed part, fixed on a body of a vehicle;
a movable part, configured to be movable between a storage position connected to the fixed part and a deployed position protruding from the fixed part toward rear of the vehicle;
an actuator, disposed on the fixed part and driving the movable part to move in a front-rear direction of the vehicle;
a rotating frame, connected to the actuator and rotating synchronously with the actuator;
a connecting member, connected to the rotating frame and the movable part; and
a locking member, disposed between the actuator and the rotating frame, applying force to the actuator through an elastic member, and locked on the rotating frame, wherein
when the movable part is in the deployed position and is subjected to a load applied from the rear toward front of the vehicle, the rotating frame is rotated by pushing the locking member against the elastic member to release fitting of the locking member, and rotates idly relative to the actuator.

### Claim 2 (depends on 1)

The movable spoiler device according to claim 1, wherein
the locking member comprises a first end and a second end,
the first end is rotatably supported by the actuator in an axial direction extending in a first direction of the vehicle, the second end is connected to the elastic member, and is locked to the rotating frame by force applied through the elastic member.

### Claim 3 (depends on 1)

The movable spoiler device according to claim 1, wherein
the carrier part of the actuator is provided with an accommodating recess for accommodating the locking member and the elastic member,
the elastic member is disposed between a first inner side wall of the accommodating recess and a first side surface of the locking member, a second side surface of the locking member abuts against a second inner side wall of the accommodating recess, and an end of the locking member corresponding to the second side surface is fitted into the rotating frame.

### Claim 4 (depends on 2)

The movable spoiler device according to claim 2, wherein
the carrier part of the actuator is provided with an accommodating recess for accommodating the locking member and the elastic member,
the elastic member is disposed between a first inner side wall of the accommodating recess and a first side surface of the locking member, a second side surface of the locking member abuts against a second inner side wall of the accommodating recess, and an end of the locking member corresponding to the second side surface is fitted into the rotating frame.

### Claim 5 (depends on 3)

The movable spoiler device according to claim 3, wherein
the rotating frame is provided with a fitting recess,
the carrier part of the actuator is provided with an extension part extending into the fitting recess, so as to drive the rotating frame to rotate synchronously, and
the end of the locking member corresponding to the second side surface is fitted into the fitting recess.

### Claim 6 (depends on 4)

The movable spoiler device according to claim 4, wherein
the rotating frame is provided with a fitting recess,
the carrier part of the actuator is provided with an extension part extending into the fitting recess, so as to drive the rotating frame to rotate synchronously, and
the end of the locking member corresponding to the second side surface is fitted into the fitting recess.
