Abstract

The invention relates to a lever aseimatic reflection sheet device, which includes a base, a leverage board and a reflection sheet device. Elastic torque of a first elastic element is provided to force the reflection sheet to touch against the windshield W with the leverage board used as rotation center of the lever, so that the reflection sheet would not be affected by vibration of vehicle dashboard, to thereby improve fastening and supporting stability of the reflection sheet.

First claim

What is claimed is:

1. A lever reflection sheet device, including:
a base;
a leverage board, a first shaft group and a second shaft group are set on the leverage board, the first shaft group includes a first elastic element and a first shaft, the first elastic element is slipped on the first shaft, the first shaft is set on a side of the leverage board and the base, the first elastic element is located between and touched the base and the leverage board to provide elastic torque for rotation;
a reflection sheet, the second shaft group is set between a bottom side of the reflection and another end of the leverage board; and
an angle adjusting mechanism, the angle adjusting mechanism includes a supporting block, an angle adjusting rod and an adjusting hole, the supporting block is set on an end of a bottom side of the leverage board, the adjusting hole is set on the reflection sheet, the angle adjusting rod is provided to be revolved into the adjusting hole, the length of the part passing over the adjusting hole and touching the supporting block is used to provide a flip angle of the reflection sheet for limit adjustment;
wherein the second shaft group includes a second elastic element being a torsion spring and a second shaft.

2. The lever reflection sheet device as claimed in claim 1 , wherein the base further includes a base plate, the base plate is set on a bottom of the base, a double-sided adhesive tap set under the base plate is provided to stick on a dashboard.

3. The lever reflection sheet device as claimed in claim 1 , wherein a damping block is set on a top side of the reflection sheet, the damping block is provided to touch on a windshield to reduce shaking of the reflection sheet.

4. The lever reflection sheet device as claimed in claim 1 , wherein the reflection sheet is a translucent and semi-reflective concave mirror.

5. A lever reflection sheet device, including:
a base;
a leverage board, a first shaft group and a second shaft group are set on the leverage board, the first shaft group includes a first elastic element and a first shaft, the first elastic element is slipped on the first shaft, the first shaft is set on a side of the leverage board and the base;
a counterweight located on an end of the leverage board;
a reflection sheet, the second shaft group is set between a bottom side of the reflection and another end of the leverage board; and
an angle adjusting mechanism, the angle adjusting mechanism includes a supporting block, an angle adjusting rod and an adjusting hole, the supporting block is set on an end of a bottom side of the leverage board, the adjusting hole is set on the reflection sheet, the angle adjusting rod is provided to be revolved into the adjusting hole, the length of the part passing over the adjusting hole and touching the supporting block is used to provide a flip angle of the reflection sheet for limit adjustment.

6. The lever reflection sheet device as claimed in claim 5 , wherein an engagement is set on an end of the leverage board for fastening the reflection sheet.

7. The lever reflection sheet device as claimed in claim 5 , wherein the base further includes a base plate, the base plate is set on a bottom of the base, a double-sided adhesive tap set under the base plate is provided to stick on a dashboard.

8. The lever reflection sheet device as claimed in claim 5 , wherein a damping block is set on a top side of the reflection sheet, the damping block is provided to touch on a windshield to reduce shaking of the reflection sheet.

9. The lever reflection sheet device as claimed in claim 5 , wherein the second shaft group is a hinge.

10. The lever reflection sheet device as claimed in claim 5 , wherein the second shaft group includes a second elastic element and a second shaft.

11. The lever reflection sheet device as claimed in claim 5 , wherein the reflection sheet is a translucent and semi-reflective concave mirror.

12. A lever reflection sheet device, including:
a base;
a leverage board, a first shaft group and a second shaft group are set on the leverage board, the first shaft group includes a first elastic element and a first shaft, the first elastic element is slipped on the first shaft, the first shaft is set on a side of the leverage board and the base, the first elastic element is located between and touched the base and the leverage board to provide elastic torque for rotation;
a reflection sheet, the second shaft group is set between a bottom side of the reflection and another end of the leverage board;
wherein a damping block is set on a top side of the reflection sheet, the damping block is provided to touch on a windshield to reduce shaking of the reflection sheet.

13. The lever reflection sheet device as claimed in claim 12 , wherein the base further includes a base plate, the base plate is set on a bottom of the base, a double-sided adhesive tap set under the base plate is provided to stick on a dashboard.

14. The lever reflection sheet device as claimed in claim 12 , wherein the second shaft group is a hinge.

15. The lever aseimatic reflection sheet device as claimed in claim 12 , wherein the second shaft group includes a second elastic element and a second shaft.

16. The lever reflection sheet device as claimed in claim 12 , further includes an angle adjusting mechanism, the angle adjusting mechanism includes a supporting block, an angle adjusting rod and an adjusting hole, the supporting block is set on an end of a bottom side of the leverage board, the adjusting hole is set on the reflection sheet, the angle adjusting rod is provided to be revolved into the adjusting hole, the length of the part passing over the adjusting hole and touching the supporting block is used to provide a flip angle of the reflection sheet for limit adjustment.

17. The lever reflection sheet device as claimed in claim 12 , wherein the reflection sheet is a translucent and semi-reflective concave mirror.
