Abstract

A road traffic warning device includes a base, a cover body mounted on the base, and a collapsible warning frame mounted to the cover body. The base includes a controlling module. A folded triangular collapsible warning frame can be unfolded out of the cover body to create the warning device. Two wheels are mounted to two side of the base. The controlling module is configured to control the wheels to move the warning device to an effective warning position.

First claim

What is claimed is:

1. A warning device comprising:
a base comprising a controller;
a cover body mounted to the base; and
a collapsible warning frame mounted to the cover body, and capable of being folded in the cover body in a first position and unfolded out of the cover body in a second position;
wherein two wheels are mounted to two side of the base, the controller is configured to control the wheels to move the warning device, the cover body comprises a cover, and an operating device mounted on a top of the cover, the cover defines an indentation, two resilient members are mounted to two ends of the indentation, the collapsible warning frame comprises a fixing plate mounted to the indentation, a first frame rotatably coupled to one end of the indentation, and a second frame rotatably coupled to other end of the indentation, the first frame and the second frame are received in the indentation and compress the two resilient members in the first position, the operating device urges the first frame and the second frame into a collapsed state, and when the operating device is separated from the collapsible warning frame, the two resilient members are restored to move the first frame and the second frame upward to the second position.

2. The warning device of claim 1 , wherein a first raised platform is formed at a side wall of the indentation, a second raised platform is formed on a front wall of the first raised platform, the fixing plate is coupled to a front side wall of the second raised platform, the first frame is located on a top of the second raised platform, and the second frame is located on a top of the first raised platform.

3. The warning device of claim 2 , wherein one end of the second raised platform defines a first receiving slot running through the first raised platform, the other end of the second raised platform defines a second receiving slot, each resilient member comprises an resilient portion, a first resilient rod coupled to one end of the resilient portion, and a second resilient rod coupled to the other end of the resilient portion, the resilient portions and second resilient rods of the two resilient members are respectively received in the first receiving slot and the second receiving slot, the first resilient rods of the two resilient members respectively urge the first frame and the second frame towards a expanded position.

4. The warning device of claim 3 , wherein a left end of a bottom wall of the first frame defines a first notch to lock the first resilient rod of one of the two resilient members, and a right end of a bottom wall of second frame defines a second notch to lock the first resilient rod of the other of the two resilient members.

5. The warning device of claim 1 , wherein a left end of the cover defines a recess communicating with the indentation, and a part of the operating device is pivotably mounted in the recess.

6. The warning device of claim 5 , wherein a bottom wall of the recess defines a first locking hole and two spaced second locking holes, the operating device comprises a head portion and an operating portion coupled to the head portion, a post protrudes from a bottom of the head portion configured to be rotatably locked in the first locking hole, a protrusion protrudes from a bottom of the operating portion, when the protrusion is locked in the right second locking hole, the operating portion urges the collapsible warning frame into the locked position, and when the protrusion is locked in the left second locking hole, the operating portion is opened into the using position from the collapsible warning frame.

7. The warning device of claim 1 , wherein a left end of the first frame defines a through hole, a post protrudes from a left end of the fixing plate configured to be rotatably locked in the through hole of the first frame.

8. The warning device of claim 1 , wherein the right end of the indentation defines a mounting hole, a post protrudes from a right end of the second frame configured to be rotatably locked in the mounting hole.

9. The warning device of claim 1 , wherein the collapsible warning frame further comprises two positioning blocks, a right end of the first frame defines a first positioning slot, a left end of the second frame defines a second positioning slot, two magnets are mounted in the first positioning slot and the second positioning slot, and when the first frame and the second frame are unfolded in the second position, the fixing plate, the first frame and the second frame cooperatively form a triangle, the magnets in the positioning blocks attract each other.

10. The warning device of claim 1 , wherein warning LEDs are mounted to the fixing plate, the first frame and the second frame.

11. A warning device comprising:
a base comprising a controller;
a cover body mounted on the base, an operating device mounted on a top of the cover body; and
a collapsible warning frame mounted to the cover body, and capable of being folded in the cover body in a first position and unfolded out of the cover body in a second position by operating the operating device;
wherein two wheels are mounted to two side of the base, the controller is configured to control the wheels to move the warning device, the cover body comprises a cover, and an operating device mounted on a top of the cover, the cover defines an indentation, two resilient members are mounted to two ends of the indentation, the collapsible warning frame comprises a fixing plate mounted to the indentation, a first frame rotatably coupled to one end of the indentation, and a second frame rotatably coupled to other end of the indentation, the first frame and the second frame are received in the indentation and compress the two resilient members in the first position, the operating device urges the first frame and the second frame into a collapsed state, and when the operating device is separated from the collapsible warning frame, the two resilient members are restored to move the first frame and the second frame upward to the second position.

12. The warning device of claim 11 , wherein a first raised platform is formed at a side wall of the indentation, a second raised platform is formed on a front wall of the first raised platform, the fixing plate is coupled to a front side wall of the second raised platform, the first frame is located on a top of the second raised platform, and the second frame is located on a top of the first raised platform.

13. The warning device of claim 12 , wherein one end of the second raised platform defines a first receiving slot running through the first raised platform, the other end of the second raised platform defines a second receiving slot, each resilient member comprises an resilient portion, a first resilient rod coupled to one end of the resilient portion, and a second resilient rod coupled to the other end of the resilient portion, the resilient portions and second resilient rods of the two resilient members are respectively received in the first receiving slot and the second receiving slot, the first resilient rods of the two resilient members respectively urge the first frame and the second frame towards a expanded position.

14. The warning device of claim 13 , wherein a left end of a bottom wall of the first frame defines a first notch to lock the first resilient rod of one of the two resilient members, and a right end of a bottom wall of second frame defines a second notch to lock the first resilient rod of the other of the two resilient members.
