Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle lighting technology, specifically a high / low beam switching device. Background Technology
[0002] Referring to patent announcement TWM248960U, "High / Low Beam Switching Device," the light shield requires two additional mounting holes and two rivets. This not only increases the manufacturing process but also results in gaps because the rivets cannot be fully fitted to the light shield during assembly. Furthermore, the two rivets pass through the mounting holes on both sides of the light shield from the front, with the engagement point located precisely on the light shield. This increases the resistance to the up-and-down movement of the light shield, and the point contact formed by the two rivets passing through the two longitudinal guide holes 24 further contributes to the problem. All of these drawbacks lead to uneven left-right swaying during the up-and-down movement control operation of the high / low beam switching device. One end of the light-shielding plate is provided with two corresponding limiting elements; the limiting element has a bent section and an extension section; these bent sections and extension sections are made by stamping and bending the light-shielding plate, which not only increases the manufacturing process, but also the limiting elements are arranged in front of the movable baffle. As described in its instruction manual, the stop part corresponds to the limiting element to limit the movement. In fact, the extension section of the limiting element will cause resistance to the vertical movement and up-down displacement of the movable baffle, which will result in the movable baffle also having the disadvantage of lateral swaying and unsmooth operation. Utility Model Content
[0003] Therefore, in order to solve the above problems, the purpose of this utility model is to provide a high / low beam switching device, comprising:
[0004] The fixing plate has a light emission notch at its top and two through-holes on both sides of its lower end.
[0005] A solenoid valve is mounted on one side of a fixed plate, and a valve shaft is provided on the top of the solenoid valve;
[0006] A light-shielding plate is installed on the side of the fixed plate with a solenoid valve. The lower end of the light-shielding plate is provided with a moving part and a stopping part. The moving part is connected to the valve shaft. The two stopping parts are arranged opposite to each other. The stopping part includes a connecting piece and a baffle plate provided at the lower end of the connecting piece. The two baffle plates extend through two limiting longitudinal guide holes respectively and are positioned by the pressure of the two limiting longitudinal guide holes.
[0007] Preferably, the valve shaft end has a recessed neck and a spring sleeve, and the front end of the moving part has a groove for nesting the neck, so that the moving part abuts against and presses against the spring.
[0008] Preferably, the light-shielding plate is an arc-shaped plate.
[0009] Preferably, the lower end of the connecting piece has an upright section, and the lower end of the inner edge of the upright section bends and extends toward the direction of the limiting longitudinal guide hole to form a baffle, and the baffle forms a surface contact with the limiting longitudinal guide hole.
[0010] The beneficial effects of this utility model are:
[0011] In this utility model, the two baffles are formed by bending the connecting piece. The baffles can extend into the preset limiting longitudinal guide hole and form surface contact with it, effectively increasing the contact area. This replaces the structure design of riveting with rivets, which can prevent the light shield connected to it from swinging left and right. The longitudinally set guide hole allows the baffles to move up and down, making the high and low beam switching operation smoother. The structure is more streamlined and the manufacturing cost is lower. Attached Figure Description

[0025] Example 1:
[0026] Figures 1-6 This invention provides a high / low beam switching device, which includes a fixing plate 10, a solenoid valve 20, and a light shield 30.
[0027] The top of the fixing plate 10 is provided with a light emission notch 11, and the lower end has two through-type limiting longitudinal guide holes 12 on both sides.
[0028] Solenoid valve 20 is installed on one side of fixed plate 10, and valve shaft 21 is provided on the top of solenoid valve 20;
[0029] The light-shielding plate 30 is an arc-shaped plate. The light-shielding plate 30 is installed on the side of the fixing plate 10 with the solenoid valve 20. The lower end of the light-shielding plate 30 is provided with a moving part 31 and a stopping part 32. The moving part 31 is connected to the valve shaft 21. The two stopping parts 32 are arranged opposite to each other. The stopping part 32 includes a connecting piece 321 and a baffle 322 provided at the lower end of the connecting piece 321. The two baffles 322 extend through the two limiting longitudinal guide holes 12 respectively and are positioned by the pressure of the two limiting longitudinal guide holes 12.
[0030] The valve shaft 21 has a neck 211 recessed at the end and a spring 22 sleeved thereon. The moving part 31 has a groove 311 at the front end for nesting the neck 211. The moving part 31 abuts against and presses against the spring 22.
[0031] The lower end of the connecting piece 321 has an upright section 3211. The lower end of the inner edge of the upright section 3211 bends and extends toward the limiting longitudinal guide hole 12 to form a baffle 322. The baffle 322 is in close contact with the inner edge of the limiting longitudinal guide hole 12.
[0032] Please refer to Figures 5 and 6, which are schematic diagrams of the high beam switching of this utility model. When the solenoid valve 20 is activated, the valve shaft 21 is pulled down directly, causing the spring 22 to be compressed. The valve shaft 21 drives the light shield 30 to move downward through the nested linkage, so that the light shield 30 no longer blocks the light emission notch 11 at the top of the fixed plate 10. This allows the light emitted by the light-emitting element in the lamp holder 40 to be completely projected out through the light emission notch 11, forming the effect of high beam illumination.
[0033] Please refer to Figures 3 and 4, which are schematic diagrams of the low beam switching of this utility model. When the solenoid valve 20 is de-energized, the spring 22 recovers elastically, pushing the linkage and valve shaft 21 upward. The light shield 30 moves upward in conjunction with the linkage. The two baffles 322 of the light shield 30 are guided upward by the two limiting longitudinal guide holes 12 and abut against the inner top edge of the two limiting longitudinal guide holes 12 for positioning. This allows the light shield 30 to block the light emitted from the top of the fixing piece 10 through the notch 11 again, forming a smaller light projection range, thus achieving the effect of conveniently switching the high beam of the vehicle headlights.
[0034] Because of the special structural design described above, this utility model has the following advantages:
[0035] Two baffles 322 are formed by bending and extending the lower end of the connecting piece 321. They face the limiting longitudinal guide hole 12 and can extend into the guide hole. The baffles 322 are formed by bending the connecting piece 321. In actual manufacturing, they are integrally formed and can replace the original complex part structure, such as the baffles 322 and connecting piece 321 being riveted together. In addition to simplifying the part structure and manufacturing process, this utility model also reduces its production cost.
[0036] When the light shield 30 moves up and down, the two baffles 322 move up and down within the guide hole, and the baffles 322 form a surface contact with the inner edge of the limiting longitudinal guide hole 12. In addition to effectively increasing the contact area and making the up and down movement of the light shield 30 more stable, it can also prevent the light shield 30 from swaying left and right during the up and down movement, thus making the overall movement smoother and effectively extending the service life of the solenoid valve 20.
[0037] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
