The guiding groove 12 has a first groove segment 120 and a second groove segment 121, and the two groove segments have the same curvature. The first groove segment 120 has a first position 122, a second position 123, and a third position 124 while the second groove segment 121 has a forth position 125, a fifth position 126, and a sixth position 127. In the embodiment, a groove segment between the first position 122 and the sixth position 127 are parallel to another groove segment of the third position 124 and the forth position 125. A first stroke 128 is defined by the second position 123, the third position 124, the forth position 125, and the fifth position 126 while a second stroke 129 is defined by the fifth position 126, the sixth position 127, the first position 122, and the second position 123. Referring to the drawings and in particular FIGS. 4 and 5, the FIG. 4 is a vertical view of a guiding groove Of the lamp structure according to the present invention, and the FIG. 5 is a sketch view of a guiding trace of the guiding groove in the FIG. 4 according to the present invention. Two ends of the second stroke 129 are aligned with tow ends of the first stroke 128 in the horizontal direction so that the second stroke 129 and the first stroke 128 are connected at the second position 123 and the fifth position 126 respectively. The second stroke 129 and the first stroke 128 have height difference h along the depth direction at the second position 123 and the fifth position 126 respectively, and the guiding groove 12 has smoothly decreasing depth along the second stroke 128 from the second position 123 to the fifth position 126 while the guiding groove 12 has smoothly decreasing depth along the second stroke 129 from the fifth position 126 to the second position 123. The sliding seat 10 has a projection 13 at one end thereof, and the projection 13 has a slot 14 on the surface and has a stopping part 15 at an end thereof. The stopping part 15 is composed of a retaining slot 150 and a retaining ring 152 at the end of the projection 13.
Referring to the drawings and in particular FIGS. 1, 2 and 3 again, the lamp seat 20 is corresponding to the conjugating seat 50, and the lamp seat 20 has a first space 21 for restricting the sliding seat 10 to moving in the first space 21. The lamp seat 20 has a first through hole 22 bored through from the surface to the first space 21 and a second space 23 been axially through to the first space 21 from the end of the lamp seat 20. The first through hole 22 is corresponding to the guiding groove 12 on the sliding seat 10. The second space 23 restricts the sliding seat 10 to moving in the second space 23. The stopping part 15 at the end of the projection 13 is axially installed outside the second space 23, and an elastic component 17 provided elasticity is axially installed at a space which the first space 21 and the second space 23 composed and has one end restricted at the retaining ring 152 of the stopping part 15. The lamp seat 20 has a second through hole 24 according to the slot 14 of the sliding seat 10, and the second through hole 24 is bored through to the second space 23. The lamp seat 20 has a carrier 25, and the carrier 25 is extended from one end of the lamp seat 20 for placing a button switch 40. The carrier 25 has a cover 26 to cover an opening thereof. The button switch 40 is percussed while the button switch 40 is pushed. The button switch 40 is also installed near the projection 13 of the sliding seat 10, and the projection 13 is pushed while the button switch 40 is percussed.
The restricting component 30 has one end inserted in the first through hole 22 of the lamp seat 20 to trace the guiding groove 12 for restricting the moving of the sliding seat 10 and has another end inserted in the second through hole 24 of the lamp seat 20 to installed at the slot 14.
Referring to the drawings and in particular FIGS. 6 and 7, the FIG. 6 is a lateral view of the lamp structure at a low beam state according to the present invention, and the FIG. 7 is a lateral view of the lamp structure at a high beam state according to the present invention. The conjugating seat 50 is installed at the lamp shell 60 while the conjugating seat 50 is engaged with the lamp seat 20. The lamp shell 60 has a cambered inner surface to reflect light emitted from the lamp seat 20, and the cambered inner surface of the lamp shell 60 has a focus which the light reflected from the cambered inner surface is focused on. At the initial state, the lamp component 11 is stood aside to the focus so that light reflected from the cambered inner surface of the lamp shell 60 comes into being a low beam. The elastic component 17 restricted by the retaining ring 152 and installed in the second space 23 provides a restrained elasticity, and the elastic component 17 is compressed during a decreasing distance between the retaining ring 152 and the second space 23. The end of the restricting component 30, the end inserted in the guiding groove 14, is stood in the second position 123 which is one end of the first stroke 128 of the guiding groove 14. The end of the second stroke 129 and the end of the first stroke 128 have the height difference h so that the restricting component 30 is restricted at the second position 12.
The restricting component 30 moves from the second position 123 of the first stroke 128 to the third position 124 of the first stroke 128 while the button switch 40 is pushed to percusse the projection 13 for moving the restricting component 30. When the restricting component 30 moves to third position 124, the elastic component 17 provides the restrained elasticity for bringing the restricting component 30 moving through the forth position 125 to the fifth position 126. The fifth position 126 is a boundary at another connected position of the second stroke 129 and the first stroke 128, and the restricting component 30 can move through the first stroke 128 to the second stroke 129 and is restrained at the fifth position 126. Therefore, the light reflected from the cambered inner surface of the lamp shell 60 comes into being a high beam. If the button switch 40 is pushed to percusse the projection 13 again, the restricting component 30 moves along the second stroke 129 and through the fifth position 126, the sixth position 127, the first position 122, until to the second position 123. The restricting component 30 passes the second stroke 129 and is restrained at the first stroke 128 near by the second position 123.
Referring to the drawings and in particular FIG. 8, another embodiment of the present invention is that the first position 122 and the sixth position 127 are reduced into one position while the first position 124 and the sixth position 125 are reduced into one position, too. Therefore, the operation of the present invention is more simply.
Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
