Description

Technical Field

[0001] The present invention belongs to the technical field of automotive lighting equipment, and more specifically, particularly relates to a magnetic levitation light-changing mechanism. Background Art

[0002] In existing automotive lighting applications, dual-beam automotive lenses have become the general trend to replace traditional high and low beam headlights that use halogen lamps as lamp beads and the lamp beads are exposed, due to their advantages such as low power consumption, high integration, high brightness, smaller volume, and more beautiful appearance. Since the high beam and low beam of the dual-beam automotive lens are integrated within the same lens, it is necessary to distinguish between the high beam and low beam. A relatively common approach is to install a light-changing structure inside the lens to achieve the purpose of switching between high beam and low beam.

[0003] The existing Chinese patent application number is: CN201620312397.2, which discloses a light-changing structure for a dual-beam automotive lens, mainly solving the problems of large volume and slow light-changing speed of the existing light-changing structure; the Chinese patent application number is: CN201620270071.8, which discloses a vehicle-mounted LED dual-beam headlight with a lens. It divides the entire lamp body into two reflective areas with different functions by using a light distribution and light-shielding plate, and can form a lamp body structure integrating high beam and low beam according to the settings of the reflective areas, and conducts light concentration through the lens, improving the light utilization rate and enhancing the lighting effect. It is not only applicable to the design of new car lights, but also meets the requirements of the car light modification field, is not restricted by the original optical path, and is suitable for popularization and application.

[0004] The above light-changing mechanisms all use an electromagnet (or motor) to perform axial movements such as horizontal and vertical directions, driving a connecting rod to perform circular movements such as up and down or rotation to achieve structural displacement. In this way, the electromagnet (or motor) itself and the associated mechanism all require several mechanical additions with springs to cooperate to achieve the required displacement. Therefore, there is significant mechanical wear and the service life is greatly limited. In the light-changing mechanism of the car lamp, due to structural reasons, there are sounds of wear and collision in the electromagnet plus the mechanism itself, and the noise is relatively large. At the same time, due to many mechanical components and large wear, after reaching a certain service life, there will be delays, slow and jerky responses, resulting in the situation that the high and low beam switching of the left and right car lights is prone to be out of sync on the left and right.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a magnetic levitation light-changing mechanism is provided with the expectation of achieving a more practical value purpose. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a magnetic levitation light-changing mechanism, which is achieved by the following specific technical means:

[0007] A magnetic levitation light-changing mechanism, including a magnetic levitation light-changing mechanism installed in a dual-light automotive lens. The magnetic levitation light-changing mechanism includes a fixed base and a light-cutting sheet. A rotating shaft horizontally penetrates through one side of the bottom of the light-cutting sheet, and connection ears for connecting both ends of the rotating shaft are provided at both ends of the top of the fixed base. One side of the fixed base is fixedly installed with a mounting bracket through a fastener. The mounting bracket is an L-shaped frame body, and its vertical end is fixedly connected to the side surface of the fixed base. An electromagnet is fixedly installed on the top side of its horizontal end. A permanent magnet is fixedly installed on the bottom side of the light-cutting sheet, and the permanent magnet is arranged above the electromagnet.

[0008] Further, the electromagnet includes an iron core, and an electromagnetic coil is installed outside the iron core.

[0009] Further, a buffer gasket is installed at the connection part of the fixed base and the mounting bracket, and a buffer spring piece is arranged at the center of the top end of the buffer gasket.

[0010] Further, a mounting bayonet is provided at one end of the bottom of the light-cutting sheet. A buffer cushion block is installed in the mounting bayonet, and one end of the buffer cushion block can be in contact with the vertical end face of the fixed base.

[0011] Further, a protective shell is installed on the top side of the mounting bracket. The protective shell is in a C-shaped and can wrap the electromagnet.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Through the combined use of the rotating shaft, permanent magnet, electromagnet and fixed base, the present invention can quickly drive the light-cutting sheet to switch between low beam and high beam. Moreover, compared with the light-changing mechanism in the prior art, the structure is relatively simple, the light-changing response time is fast, the consistency of the light-changing frequency can be effectively improved. At the same time, in this magnetic levitation light-changing mechanism, the light-cutting sheet and the fixed base are only connected through the rotating shaft, without other mechanical structures for connection. Therefore, the wear can be minimized to the greatest extent, so that the magnetic levitation light-changing mechanism has better stability and longer service life during use, and can ensure better quietness during use.

[0025] Example:

[0026] As shown in the attached Figure 1 to the attached Figure 6 shown:

[0027] The present invention provides a magnetic levitation light-changing mechanism, including a magnetic levitation light-changing mechanism 1 installed in a dual-light automotive lens. The magnetic levitation light-changing mechanism 1 includes a fixed base 101 and a light-cutting sheet 102. A rotating shaft 103 horizontally penetrates through one side of the bottom of the light-cutting sheet 102, and connecting ears for connecting both ends of the rotating shaft 103 are provided at both ends of the top of the fixed base 101. One side of the fixed base 101 is fixedly installed with a mounting bracket 105 through a fastener. The mounting bracket 105 is an L-shaped frame body, and its vertical end is fixedly connected to the side surface of the fixed base 101. An electromagnet is fixedly installed on the top side of its horizontal end. A permanent magnet 104 is fixedly installed on the bottom side of the light-cutting sheet 102, and the permanent magnet 104 is arranged above the electromagnet.

[0028] Among them, the electromagnet includes an iron core 106, and an electromagnetic coil 107 is installed on the outer side of the iron core 106. Through the setting of the electromagnet, when the electromagnetic coil 107 is energized, one end of the iron core 106 can be magnetized, and in cooperation with the permanent magnet 104, the light-cutting sheet 102 can be quickly driven, thereby realizing a quick high-low beam switching.

[0029] Among them, a buffer gasket 109 is installed at the connection part of the fixed base 101 and the mounting bracket 105. A buffer spring piece is arranged at the center of the top end of the buffer gasket 109. Through the setting of the buffer spring piece, when the light-cutting sheet 102 is flipped to switch to the high beam, it can be avoided that it directly impacts the top side of the fixed base 101, thereby improving the overall service life of the mechanism to a certain extent, and at the same time reducing the noise during the switching.

[0030] Among them, a mounting bayonet is provided at one end of the bottom of the light-cutting sheet 102, and a buffer cushion block 1010 is installed in the mounting bayonet, and one end of the buffer cushion block 1010 can be in contact with the vertical end surface of the fixed base 101. Through the buffer cushion block 1010, when the light-cutting sheet 102 is flipped to switch to the low beam, it can be avoided that it directly impacts the top side of the fixed base 101, thereby improving the overall service life of the mechanism to a certain extent, and at the same time reducing the noise during the switching.

[0031] Among them, a protective shell 108 is installed on the top side of the mounting bracket 105. The protective shell 108 is in a C-shaped form and can wrap the electromagnet. Through the setting of the protective shell 108, the electromagnet can be isolated and protected, thereby facilitating the improvement of its stability.

[0032] The working principle of this embodiment:

[0033] Before use, first correctly install this magnetic levitation light-changing mechanism inside the dual-beam automotive lens. Then, during use, by controlling the current direction of the electromagnetic coil 107, the magnetism of the electromagnet can be adjusted to achieve adsorption or repulsion of the permanent magnet 104 above it. In the initial state, the electromagnet adsorbs the permanent magnet 104, causing the light-cutting sheet 102 to partially block the light, thereby transforming the automotive lens into the low-beam state. When switching to the high-beam, by controlling the electromagnet to repel the permanent magnet 104, the light-cutting sheet 102 rotates upward around the rotating shaft 103. At this time, the light will not be blocked by the light-cutting sheet 102, realizing the transformation of the automotive lens into the high-beam state. Through the combined use of the rotating shaft 103, the permanent magnet 104, the electromagnet, and the fixed base 101, the present invention can quickly drive the light-cutting sheet 102 to switch between high and low beams. Moreover, compared with the light-changing mechanisms in the prior art, the structure is relatively simple, the light-changing response time is fast, the consistency of the light-changing frequency can be effectively improved. At the same time, in this magnetic levitation light-changing mechanism, the light-cutting sheet 102 is only connected to the fixed base 101 through the rotating shaft 103, without other mechanical structures for connection. Thus, the wear can be minimized to the greatest extent, enabling the magnetic levitation light-changing mechanism to have better stability and a longer service life during use, and ensuring better quietness during use.
