[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0021] See also Figure 1 and Figure 2An embodiment of the high and low beam switching device of the present invention is suitable for installation in vehicles such as automobiles and motorcycles, and is used in conjunction with a light source 10. The high and low beam switching device includes a housing 1, a light shape switching unit 2 and a driving unit 3.

[0022] The housing 1 includes a base 11, a setting space 12, a light channel 13 and two embedding grooves 14. The base 11 has a horizontal upward mounting surface 111 and a reflecting surface 112 extending upward and forward from the rear side edge of the mounting surface 111. The setting space 12 is defined by the mounting surface 111 and the reflecting surface 112, and is used for the light source 10 to be set on the mounting surface 111 and for the light emitted by the light source 10 to be reflected by the reflecting surface 112. The light channel 13 is located in front of the setting space 12, and is used for the light reflected by the reflecting surface 112 to pass through. The embedding grooves 14 are respectively formed at opposite ends of the surface on the front side of the base 11.

[0023] The light shape switching unit 2 includes a light shape plate 21 , a limiting protrusion 22 , an elastic member 23 , a shaft 24 and two fixing components 25 .

[0024] The light-shaped plate 21 is located in front of the light channel 13 and is used to generate a low-beam light shape. The light-shaped plate 21 has a shielding portion 211 for shielding light, a connecting portion 212 for connecting the shielding portion 211 with the elastic member 23 and the shaft 24, and two lug portions 213 arranged at intervals and located at one end of the connecting portion 212 away from the shielding portion 211 for the shaft 24 to be set. The shielding portion 211 has a first plane section 214, a second plane section 215, and a slope section 216 for connecting the first plane section 214 and the second plane section 215. The first plane section 214, the second plane section 215 and the slope section 216 together form a low-beam light shape structure, so that the light irradiating the shielding portion 211 generates a low-beam light shape. The light-shaped plate 21 can be switched between the low-beam position and a high-beam position that does not shield the light passing through the light channel 13.

[0025] The limiting protrusion 22 is located on the side of the light-shaped plate 21 adjacent to the setting space 12 and has two limiting protrusions 221, a limiting connection section 222 and a through hole 223. The limiting protrusions 221 protrude from the light-shaped plate 21 and are arranged in parallel and spaced apart. The limiting connection section 222 is used to connect the end of the limiting protrusion 221 away from the light-shaped plate 21, and the limiting protrusion 221 and the limiting connection section 222 jointly define the through hole 223.

[0026] The elastic member 23 is used to push the light-shaping plate 21 toward the low-beam position for shielding the light passing through the light channel 13 . In the present embodiment, the elastic member 23 is a return spring.

[0027] The shaft 24 is used for the elastic member 23 to be wound around and to pass through the lug portion 213 of the light-shaped plate 21 , and opposite ends of the shaft 24 can be correspondingly placed in the embedding groove 14 .

[0028] The fixing assembly 25 is used to fix the light-shaped plate 21, the elastic member 23 and the shaft 24 to the front surface of the base 11 of the housing 1, and each fixing assembly 25 has a head 251, a threaded portion 252, and a flange portion 253 extending outward from the periphery of the head 251. When the fixing assembly 25 fixes the light-shaped plate 21, the elastic member 23 and the shaft 24 to the base 11, the flange portion 253 will be attached to the front surface of the base 11. In this embodiment, the fixing assembly 25 is two flange screws arranged at intervals.

[0029] The driving unit 3 includes a driving rod 31 and a power assembly 32. The driving rod 31 is disposed in the through hole 223 of the limiting protrusion 22. The driving rod 31 has a main rod portion 311 pivotally disposed on the power assembly 32 and a cross rod portion 312 located at one end of the main rod portion 311 away from the power assembly 32 and passing through the through hole 223 of the limiting protrusion 22, and is used to drive the light-shaped plate 21 to switch between the low-beam position and the high-beam position, that is, the cross rod portion 312 is used to limit the elastic member 23 from pushing the light-shaped plate 21 away from the low-beam position, and drive the light-shaped plate 21 to switch to the high-beam position. When the power assembly 32 drives the crossbar 312 by pulling the main rod 311 downward, the crossbar 312 abuts against the limit protrusion 22 and drives the light-shaped plate 21 to switch to the high beam position; when the power assembly 32 stops pulling the main rod 311, the crossbar 312 temporarily moves away from the limit protrusion 22 so that the elastic member 23 pushes the light-shaped plate 21 to switch to the low beam position. The power assembly 32 is used to provide power to drive the driving rod 31 to move. In this embodiment, the power assembly 32 is a solenoid valve. The moving distance of the driving rod 31 is accurately controlled by the solenoid valve, so that the driving rod 31 can accurately drive the light-shaped plate 21 to switch between the low beam position and the high beam position through the limit protrusion 22, so that the high and low beam switching device has a better effect when switching between the high beam and the low beam.

[0030] See also Figure 2When the high and low beam switching device is used, a high beam mode and a low beam mode can be switched according to the needs of the user. In the high beam mode, when the main rod portion 311 of the driving rod 31 is driven by the power assembly 32, the cross bar portion 312 of the driving rod 31 is driven to move downward and abut against the limiting protrusion 22 of the light-shaped plate 21, so as to further drive the shielding portion 211 of the light-shaped plate 21 to swing downward and move toward the high beam position close to the mounting surface 111 of the base 11, so that the light emitted by the light source 10 installed in the setting space 12 is not shielded when it is reflected by the reflective surface 112 of the base 11 and passes through the light channel 13, and the light presented is the high beam. When the cross bar portion 312 drives the light-shaped plate 21 to swing downward, the elastic member 23 will begin to accumulate elastic force due to compression.

[0031] See also Figure 3 When the high and low beam switching device is switched to the low beam mode, the power assembly 32 stops driving the main rod 311 of the driving rod 31 to move downward, thereby causing the cross rod 312 of the driving rod 31 to temporarily leave the limiting protrusion 22. At this time, the elastic member 23 applies elastic force to the connecting portion 212 of the light-shaped plate 21 and pushes the light-shaped plate 21 to swing in the direction of the low beam position. When the light-shaped plate 21 swings in the direction of the low beam position, the cross rod 312 will again abut against the limiting protrusion 22 to limit the swing amplitude of the light-shaped plate 21 so that it can stay in the low beam position. In the low beam position, the shielding portion 211 of the light-shaped plate 21 will shield the light passing through the light channel 13, and make the light present the light shape of the low beam due to the first plane section 214, the second plane section 215 and the inclined section 216 of the shielding portion 211.

[0032] It is worth mentioning that the high and low beam switching device of the present invention arranges the power assembly 32 and the driving rod 31 below the light-shaping plate 21, and the cross bar portion 312 of the driving rod 31 is passed through the through hole 223 of the limiting protrusion 22, so that the driving rod 31 can control the actuation of the light-shaping plate 21 with the shortest moving distance without wasting space, so as to achieve the purpose of switching the high and low beams.

[0033] To sum up, the high and low beam switching device of the present invention only sets the limiting protrusion 22 and the elastic member 23 on the light-shaping plate 21, so that the driving rod 31 can be connected to the light-shaping plate 21 in a simple installation manner of passing the cross bar portion 312 through the limiting protrusion 22, and cooperates with the elastic member 23 to drive the light-shaping plate 21 to switch between the high beam position and the low beam position, so the purpose of the present invention can be achieved.

[0034] However, the above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
