Description

Technical Field

[0001] The present application relates to a light source switching device, and particularly to a light source switching device with a streamlined structure. Background Art

[0002] As mentioned in the background art of the headlight high-low beam switching device 1 (as shown in Figure 1 ), which is installed between the lamp holder combined with the light-emitting element and the light-transmitting cover, the high-low beam switching device 1 includes: a fixing piece 11, a solenoid valve 12, a light-shielding plate 13, an elastic fastener 14, a pulling piece 15, and a lining plate (located behind the fixing piece 11). It mainly controls the size of the light projection area by directly pulling down the pulling piece 15 to drive the light-shielding plate 13 to swing by the telescopic movement of the valve shaft rod 120 of the solenoid valve 12, so as to achieve high-low beam switching.

[0003] However, the high-low beam switching device 1 of the above-mentioned vehicle lamp has the following disadvantages: (1) The existing high-low beam switching device 1 is composed of a fixing piece 11, a solenoid valve 12, a light-shielding plate 13, an elastic fastener 14, a pulling piece 15, and a lining plate (located behind the fixing piece 11). The components are complicated, not only time-consuming and laborious to assemble, but also the manufacturing cost of each component is high, and the assembly lacks efficiency. (2) Pivot seats 111 are punched on both sides of the notch 110 of the fixing piece 11, resulting in perforations formed beside the pivot seats 111. Therefore, a lining plate must be combined separately to cover the perforations. Obviously, the lining plate does not provide the function of the switching device, but is a supplementary part derived from the design defect.

[0004] Patent Publication No. TW M454948U, with the patent name "Motorcycle High-Low Beam Switching Device", uses a connecting part to be fixed to a linkage part, so that when the electromagnetic unit is actuated, the linkage part pulls the connecting part, thereby displacing the movable baffle. Among them, the patent uses a limiting element arranged on the light-shielding plate to limit the stopping part of the movable baffle. However, the patent forms the limiting element on the plate surface of the light-shielding plate by processes such as punching and folding. If the processing accuracy of processes such as punching and folding is insufficient, problems such as inaccurate position of the limiting element or insufficient space for the limiting element to accommodate the stopping part may occur, and thus the displacement position of the movable baffle may have errors in this patent.

[0005] Patent Publication No. TW M517120U, with the patent name "Light Source Switching Device", uses an extended cantilever arranged at the middle section of the lower side of the shielding unit to connect to a driving part, so that when the magnetic valve unit is actuated, the driving part pulls the shielding unit, and then the shielding unit is displaced. However, due to the offset of the acting point of the force, problems such as shaking or tilting may occur when the shielding unit is displaced, and thus there is a problem that the displacement of the shielding unit is not stable enough.

[0006] In summary, the applicant of the present application has many years of experience in the manufacturing, development, and design of related products. A light source switching device is designed for the above-mentioned objectives to improve the deficiencies of the prior art and thus promote its industrial implementation and utilization.

The linkage member is connected to the magnetic valve member and movably passes through the through-opening. The linkage member is driven by the magnetic valve member to displace. In the first direction, opposite sides of the shielding member respectively have a fixing portion and a shielding portion. The fixing portion is fixed to an end of the linkage member away from the magnetic valve member. The elastic member is located between the fixing portion and the magnetic valve member. The shielding portion corresponds to the notch and shields or does not shield the notch when driven by the linkage member.

[0009] Preferably, in a second direction, opposite sides of the magnetic valve member respectively have limiting portions; the first direction is perpendicular to the second direction. In the second direction, opposite sides of the fixing portion respectively extend to form extending arms. The extending arms extend to a side of the limiting portion facing away from the notch.

[0010] Preferably, the limiting portion has an L-shaped structure. The short arm of the limiting portion is integrally connected to the magnetic valve member, and the long arm of the limiting portion has a gap with the magnetic valve member.

[0011] Preferably, the extending arm extends from a direction away from the fixing portion, then extends in the direction of the magnetic valve member, passes through the gap, and then turns to a side of the limiting portion facing away from the notch.

[0012] Preferably, the fixing member respectively has bending limiting portions corresponding to the shielding member on both sides of the notch on the notch side.

[0013] Preferably, the fixing position of the fixing portion and the linkage member is at the midpoint of the width of the fixing portion.

[0014] Preferably, two connecting arms are provided on the side of the shielding member having the fixing portion. The two connecting arms are spaced apart from the fixing portion respectively, and the connecting arms extend and are connected to the portion of the extending arm on the side of the limiting portion facing away from the notch.

[0019] (1) The light source switching device of the present application can drive the shielding member to selectively shield or disengage from the notch of the fixing member through the magnetic valve member and the linkage member, thereby solving the problems of the complex components of the existing high and low beam switching device of vehicle lights, which not only takes time and effort in assembly, but also has high manufacturing costs for each component and lacks efficiency in assembly.

[0020] (2) The light source switching device of the present application can, through the configuration of the limiting portion and the extending arm, achieve stable displacement of the shielding member to shield or disengage from the notch under the conditions of simplified components, effective cost reduction, and improved economic benefits, thereby increasing the stability of light source switching.

It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this application, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0035] It should also be understood that the terms used in this application are for the purpose of describing particular embodiments only and are not intended to limit this application. As used in the specification of this application and / or the appended claims, unless the context clearly indicates otherwise, the singular forms "a" and "the" are intended to include the plural forms.

[0036] Please refer to Figures 2 to 4 together. Figure 2 is an exploded view of the first embodiment of the light source switching device of this application. Figure 3 and 4 is a combined view of the first embodiment of the light source switching device of this application in different states. As shown in the figure, the light source switching device 2 of this application can be applied to the headlights of mobile vehicles (such as locomotives or automobiles, etc.). The light source switching device 2 of this application mainly includes a fixing member 21, a solenoid member 22, a linkage member, and a shielding member 24.

[0037] Among them, the fixing member 21 can be made of a metal material, and it has opposite notch sides 211 and a fixing side 212 in the first direction D1. Among them, the notch side 211 has a notch 213; the notch 213 can be in a semicircular, triangular or any suitable geometric shape. Incidentally, the light source switching device 2 can be fixed or combined with the headlight lamp cover through the fixing member 21 and is located in front of the lamp core of the headlight. The way it is fixed or combined with the headlight lamp cover is well-known or commonly used technical means for those skilled in the technical field, and will not be elaborated herein.

[0038] Among them, the magnetic valve member 22 is a component well-known or commonly used by those skilled in the art of the relevant technical field, and will not be elaborated herein. The magnetic valve member 22 is disposed on the fixing member 21 and adjacent to the fixed side 212, and can be set or fixed, for example, by screwing. It is worth mentioning that the magnetic valve member 22 has a through hole 221; the opening direction of the through hole 221 corresponds to the first direction D1. Among them, the linkage member 23 is connected to the magnetic valve member 22 and is movably disposed in the through hole 221. Therefore, the linkage member 23 is driven by the magnetic valve member 22 to reciprocate along the first direction D1 or the axial direction of the through hole 221.

[0039] Among them, the shielding member 24 can be made of a metal material. On the first direction D1, the two opposite sides of the shielding member 24 respectively have a fixing portion 241, a shielding portion 242 and an elastic member 243. The fixing portion 241 is fixed to the end of the linkage member 23 away from the magnetic valve member 22. The elastic member 243 is sleeved on the linkage member 23 and is located between the fixing portion 241 and the magnetic valve member 22. Incidentally, the fixing portion 241 can have a through hole. After one end of the linkage member 23 passes through the through hole, it is fixed by using components such as a C-shaped buckle; or, the fixing portion 241 and one end of the linkage member 23 can be fixed by screwing or buckling. The shielding portion 242 corresponds to the notch 213 and shields or does not shield the notch 213 when driven by the linkage member 23.

[0040] Specifically, when the vehicle lamp desires to control the light source to be a high beam, the vehicle lamp or the moving vehicle can energize the magnetic valve member 22. After the magnetic valve member 22 is energized, the magnetic valve member 22 will generate a magnetic suction force to attract the linkage member 23, so as to drive the linkage member 23 to displace in the direction of the magnetic valve member 22 and drive the shielding member 24 to displace in the direction of the magnetic valve member 22, so that the shielding portion 242 disengages from the notch 213 and does not shield the notch 213. At this time, both the low beam light source and the high beam light source of the vehicle lamp can pass through the notch 213, thereby achieving the state that the vehicle lamp is a high beam.

[0041] On the contrary, when the vehicle lamp desires to control the light source to be a low beam, the vehicle lamp or the moving vehicle can cut off the power supply of the magnetic valve member 22, so that the magnetic valve member 22 stops generating a magnetic suction force. At this time, the shielding member 24 will be pushed by the elastic restoring force of the elastic member 243 and displace in the direction of the notch 213, so that the shielding portion 242 shields the notch 213, thereby shielding the high beam light source of the vehicle lamp, so that only the low beam light source passes through the notch 213, achieving the state that the vehicle lamp is a low beam.

[0042] Thus, the light source switching device 2 of the present application can drive the linkage member 23 to move through the magnetic valve member 22, so that the shielding member 24 selectively shields or disengages from the notch 213, thereby solving the problems of the parts and components of the existing high and low beam switching device 1 of vehicle headlights being complex, not only time-consuming and laborious in assembly, but also high in manufacturing cost of each component and lacking in assembly efficiency. In contrast, through this structural design, the light source switching device 2 of the present application not only simplifies the components, but also can effectively reduce costs and improve economic benefits.

[0043] Furthermore, in the second direction D2 perpendicular to the first direction D1, the opposite sides of the magnetic valve member 22 respectively have limiting portions 222. Among them, the limiting portion 222 has an L-shaped structure. The short arm of the limiting portion 222 is integrally connected to the magnetic valve member 22, and there is a gap 223 between the long arm of the limiting portion 222 and the magnetic valve member 22. Correspondingly, in the second direction D2, the opposite sides of the fixing portion 241 respectively extend to form extension arms 244. The extension arms 244 extend to the side of the limiting portion 222 facing away from the notch 213. Among them, the extension arms 244 extend in the direction away from the fixing portion 241, then extend towards the magnetic valve member 22, pass through the gap 223 and then turn to the side of the limiting portion 222 facing away from the notch 213.

[0044] It is worth mentioning that the midpoint of the width of the extension arm 244 is aligned with the center point of the fixing position of the fixing portion 241 and the linkage member 23. Preferably, the fixing position of the fixing portion 241 and the linkage member 23 is located at the midpoint of the width of the fixing portion 241.

[0045] Thus, when the shielding member 24 is pushed by the elastic restoring force of the elastic member 243, the limiting portion 222 can resist the part of the extension arm 244 located on the side of the limiting portion 222 facing away from the notch 213, thereby avoiding the linkage member 23 being separated from the through hole 221 of the magnetic valve member 22 under the influence of the elastic restoring force. In addition, due to the extension arm 244 passing through the gap 223, and / or the midpoint of the width of the extension arm 244 being aligned with the center point of the fixing position of the fixing portion 241 and the linkage member 23, and / or the fixing position of the fixing portion 241 and the linkage member 23 being located at the midpoint of the width of the fixing portion 241 and other configurations, the problem of the positioning accuracy of the shielding member 24 and the problem of possible shaking when the shielding member 24 is pulled can be improved, and further the displacement of the shielding member 24 is made more stable.

[0046] Incidentally, the fixing member 21 respectively has bending limiting portions 214 corresponding to the shielding member 24 on both sides of the notch 213 on the notch side 211. The bending limiting portions 214 can also achieve the purpose of resisting the shielding member 24 to prevent the linkage member 23 from being separated from the through hole 221 of the magnetic valve member 22 under the influence of the elastic restoring force.

In this embodiment, elements with the same reference numerals have the same or similar configurations and operations as those in the foregoing embodiments, and the same or similar parts will not be described herein again.

[0048] The main difference between this embodiment and the foregoing embodiments lies in the arrangement of the limiting portion 222 and the extension arm 244. Among them, the limiting portion 222 is a wing portion directly extended from the solenoid valve member 22, and the extension arm 244 is extended directly from the side of the shielding member 24 having the fixing portion 241 and then turned to the side of the limiting portion 222 facing away from the notch 213; or, it is arranged to be extended directly from both sides of the fixing portion 241 (in the second direction D2) and then turned to the side of the limiting portion 222 facing away from the notch 213.

In this embodiment, elements with the same reference numerals have the same or similar configurations and operations as those in the foregoing embodiments, and the same or similar parts will not be described herein again.

[0050] The main difference between this embodiment and the foregoing embodiments lies in the arrangement of the limiting portion 222 and the extension arm 244. Further, two connecting arms 245 are provided on the side of the shielding member 24 having the fixing portion 241; the two connecting arms 245 are spaced apart from the fixing portion 241 respectively. Preferably, the two connecting arms 245 are symmetrically arranged with the fixing portion 241 as the reference or with the midpoint of the width of the fixing portion 241 as the reference.

[0051] Among them, the connecting arm 245 extends and is connected to the extension arm 244 located on the side of the limiting portion 222 facing away from the notch 213, and the connecting arm 245 extends away from the shielding member 24 in the first direction D1 and then is turned and connected to the extension arm 244.
