Abstract

A protection device of self-propelled vehicle including a main body, a frame body, and at least two pivoting members is provided. The main body has a rail or a moving block, and the frame body has a moving block or a rail. The frame body moves on a plane relative to the main body via the moving block being removably coupled to the rail. The two pivoting members being removably pivoted to the main body and the frame body along two normal lines of the plane respectively. The frame body is forced to be rotated on the plane with one of the two pivoting members relative to the main body.

Claims

1. A protection device of self-propelled vehicle, comprising:

a main body having a rail or a moving block;

a frame body having a moving block or a rail, and the frame body moving on a plane relative to the main body via the moving block being removably coupled to the rail; and

at least two pivoting members being removably pivoted to the main body and the frame body along two normal lines of the plane respectively, and the frame body being forced to be rotated on the plane with one of the two pivoting members relative to the main body.

2. The protection device of self-propelled vehicle according to claim 1, wherein the protection device of self-propelled vehicle has a central axis, and the rail and the moving block are located on the central axis.

3. The protection device of self-propelled vehicle according to claim 2, wherein the two pivoting members are symmetrical relative to the central axis.

4. The protection device of self-propelled vehicle according to claim 1, wherein the rail is a groove structure, the groove structure has two vias on at least one sidewall, and the two pivoting members are connected to the moving block through the two vias respectively.

5. The protection device of self-propelled vehicle according to claim 4, wherein the two vias are expanded holes respectively, and an expanding direction thereof comprises a rotation direction of the frame body relative to the main body on the plane.

6. The protection device of self-propelled vehicle according to claim 5, wherein the expanding direction further comprises a translation direction without rotation of the frame body relative to the main body on the plane.

7. The protection device of self-propelled vehicle according to claim 4, wherein the groove structure has two vias on each of two sidewalls, and the protection device of self-propelled vehicle comprises four pivoting members connected to the moving block through the vias along four normal lines of the plane respectively.

8. The protection device of self-propelled vehicle according to claim 6, further comprising:

at least two sensors disposed in the moving block, when the frame body is rotated on the plane with one of the two pivoting members relative to the main body, one of the at least two sensors is triggered since structures of the moving block and the main body are moved closer to each other, and when the frame body is translated without rotation on the plane relative to the main body, the at least two sensors are triggered at the same time since the structures of the moving block and the main body are moved closer to each other.

9. The protection device of self-propelled vehicle according to claim 1, wherein the frame body further comprises a plurality of protruding rib structures to improve structural strength of the frame body, and when the frame body is rotated relative to the main body, the frame body is not deformed.

10. The protection device of self-propelled vehicle according to claim 1, further comprising:

a pair of power wheels disposed at the main body, wherein an interval of the two pivoting members is less than an interval of the pair of power wheels.
