The embodiments of the light source switching device according to the present invention will be described below with reference to the related drawings. For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals.

Please refer to FIG. 3 and FIG. 4 , which are respectively a first schematic diagram and a second schematic diagram of the first embodiment of the light source switching device. As shown, the light source switching device 2 includes a fixed unit 20, a magnetic valve unit 21, a driving member 211, and a shielding unit 22. The fixing unit 20 has a notch 200 at one end. The magnetic valve unit 21 is connected to the fixed unit 20, and the magnetic valve unit 21 has a limit opening 210 at one end. The driving member 211 is movably disposed through the limiting opening 210 and the magnetic valve unit 21 . The shielding unit 22 is coupled to the driving member 211. Wherein, when the magnetic valve unit 21 is powered, the magnetic valve unit 21 drives the driving member 211 to be displaced toward the other end of the magnetic valve unit 21 to drive the shielding unit 22 to be displaced in the first direction to open the notch 200; When the power is off 21 , the shielding unit 22 is displaced by the thrust in the second direction to shield the notch 200.

Specifically, the light source switching device 2 of the present invention can be applied to a vehicle of a mobile vehicle (such as a locomotive or an automobile). The light source switching device 2 includes a fixing unit 20, a magnetic valve unit 21, a driving member 211, and a shielding unit. twenty two. The light source switching device 2 can be coupled to the lampshade by the fixing unit 20 and located at a position in front of the wick of the lamp. The fixing unit 20 has a notch 200 at one end, the fixing unit 20 is connected to the magnetic valve unit 21, and the magnetic valve unit 21 has a limiting opening 210 at one end. The limiting opening 210 can be semi-circular, triangular or any geometrical shape, and the driving member 211 can be movable. The grounding member 210 is disposed in the limiting opening 210 and the magnetic valve unit 21, and a part of the driving member 211 is specifically located in the magnetic valve unit 21, and another portion of the driving member 211 is movably reciprocally displaced from the limiting opening 210. The shielding unit 22 is coupled to the driving member 211.

When the vehicle lamp is to control the light source to be a high beam lamp, the vehicle lamp or the mobile vehicle can energize the magnetic valve unit 21, and after the magnetic valve unit 21 is powered, the magnetic valve unit 21 generates a magnetic attraction force, and the driving member 211 is adsorbed. The driving member 211 is driven to be displaced toward the other end of the magnetic valve unit 21, and the blocking unit 22 is displaced in the first direction (the axial direction in which the driving member 211 is displaced toward the other end of the magnetic valve unit 21), so that the shielding unit 22 opens the gap. 200. At this time, the low beam light source and the high beam light source of the lamp can pass through the gap 200, thereby achieving the state that the headlight is a high beam.

Conversely, when the vehicle lamp is to control the light source to be a low beam, the vehicle lamp or the mobile vehicle can power off the magnetic valve unit 21, so that the magnetic valve unit 21 stops generating magnetic attraction, and at this time, the shielding unit 22 is driven. The thrust of the piece 211 or the elastic component (such as a spring) is displaced in the second direction (the axial direction in which the driving member 211 is displaced toward the outside of the magnetic valve unit 21) to shield the notch 200, thereby shielding the high beam source of the lamp So that only the low beam light source A passes through the notch 200, and the vehicle lamp is in the low beam state.

Therefore, the light source switching device 2 of the present invention can drive the driving member 211 to actuate by the magnetic valve unit 21, so that the shielding unit 12 selectively opens or shields the notch 200 of the fixing unit 20 to solve the near-light switching of the conventional vehicle lamp. The components of the device 1 are complicated, and it is not only complicated to assemble, time-consuming, and the manufacturing cost of each component is high, and the assembly is inefficient. In contrast, the light source switching device 2 of the present invention is designed not only to be compact, but also to effectively reduce costs and improve economic efficiency.

Further, the magnetic valve unit 21 may include a base 212 and a solenoid valve member 213. The base 212 is coupled to the fixed unit 2, and the base 212 has a limiting opening 210 at one end. The electromagnetic valve member 213 is located in the base 212, and the driving member 211 is movably disposed through the limiting opening 210 and the electromagnetic valve member 113. That is to say, the magnetic valve unit 21 of the present invention further includes a base 212 and a solenoid valve member 213. The base 212 may be a housing structure having a limiting opening 210 at one end thereof, and the electromagnetic valve member 213 may be disposed in the base 212. The driving member 211 is movably disposed in the limiting opening 210 and the body of the electromagnetic valve member 113.

Further, the driving member 211 has a limiting portion 211A on one side thereof, and the limiting portion 211A is movably disposed through the limiting opening 210. When the electromagnetic valve member 213 is powered, the electromagnetic valve member 213 drives the driving member 211 toward the electromagnetic valve. The member 213 is displaced at one end to drive the shielding unit 12 to be displaced in the first direction to open the notch 200. When the electromagnetic valve member 213 is not charged, the shielding unit 22 is displaced by the thrust in the second direction to shield the notch 200.

For example, the driving member 211 can be recessed inwardly to form a limiting portion 211A, and the limiting portion 211A can be matched to the shape of the limiting opening 210. Thereby, the limiting opening 210 is used to suppress the axial rotation of the driving member 211, so that the driving member 211 can be vertically reciprocally displaced in the limiting opening 210 when the electromagnetic valve member 213 is powered or unpowered. Moreover, when the driving member 211 is displaced to the outside of the electromagnetic valve member 213, the displacement distance of the driving member 211 can be restricted by the limiting portion 211A, the top and bottom limiting openings 210, and the driving member 211 can be prevented from coming off the electromagnetic valve member 213.

Please refer to FIG. 5 , which is a schematic diagram of a first embodiment of the light source switching device of the present invention, and please refer to FIG. 3 and FIG. 4 together. As shown in the figure, the light source switching device in this embodiment is similar to the operation of the same components described in the light source switching device of the first embodiment, and therefore will not be described herein. However, it is worth mentioning that, in this embodiment, the light source switching device 2 preferably further includes an elastic unit 23 disposed on the driving member 211 and located between the shielding unit 22 and the magnetic valve unit 21 at the magnetic valve. When the unit 21 is not powered, the elastic unit 23 generates a thrust force to the shielding unit 22 by its elastic tension, so that the shielding unit 22 shields the notch 200.

For example, the light source switching device 1 of the present invention may further be provided with an elastic unit 23 (such as a spring) that can be sleeved on the driving member 211 and located between the shielding unit 22 and the magnetic valve unit 21. Therefore, when the magnetic valve unit 21 is not energized and no magnetic attraction force is generated, the elastic unit 23 can abut against the shielding unit 22 and the magnetic valve unit 21 by its elastic tension, and generate a thrust force to the shielding unit 22, thereby causing the shielding unit to be blocked. 22 displacement and shielding the notch 200, so that the lamp is in the low beam state.

Please refer to FIG. 6 , which is a schematic diagram of a third embodiment of the light source switching device of the present invention, and please refer to FIG. 3 and FIG. 4 together. As shown in the figure, the light source switching device in this embodiment is similar to the operation of the same components described in the light source switching devices of the above embodiments, and therefore will not be described herein. However, it is worth mentioning that, in this embodiment, the light source switching device 2 preferably further includes an elastic unit 23 disposed between the driving member 211 and the other end of the magnetic valve unit 21, not in the magnetic valve unit 21. When the power is received, the elastic unit 23 drives the driving member 211 to be displaced toward one end of the magnetic valve unit 21 by the elastic tension thereof, so that the driving member 211 generates a thrust force on the shielding unit 22, thereby blocking the shielding unit 22 from covering the notch 200.

Specifically, in another embodiment, the light source switching device 1 of the present invention may further provide an elastic unit 23 (such as a spring) between the driving member 211 and the other end of the magnetic valve unit 21. Therefore, when the magnetic valve unit 21 is not energized and no magnetic attraction force is generated, the elastic unit 23 can be abutted against the driving member 211 and the magnetic valve unit 21 by its elastic tension, and is pushed against the driving member 211 to be displaced. The abutting driving member 211 can generate a thrust on the shielding unit 22, thereby driving the shielding unit 22 to displace and cover the notch 200, so that the vehicle lamp is in the low beam state.
