Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle headlight dimming technology, and more specifically, to a vehicle headlight color-changing mechanism. Background Technology
[0002] A Taiwanese patent with publication number TWM461734U discloses a lamp color temperature rotation device. It mainly involves installing a rotating mechanism on a lamp holder with a light source and placing a colored lens on the rotating mechanism. The rotating mechanism drives the colored lens to rotate, so that the light emitted by the lamp can present the original color of the light source, or the color temperature of the light can be changed by the colored lens to emit another color of light.
[0003] However, the aforementioned rotating mechanism uses a motor as its power source, which is costly. Moreover, for space configuration reasons, the rotating mechanism uses a set of bevel gears for transmission, which not only results in a slow response speed but also requires a motor with a large output torque and a relatively large size, thus increasing the cost and making space configuration design more difficult. In addition, it generates noise during operation. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] This utility model provides a vehicle headlight color-changing mechanism, such as Figure 1 As shown, it includes: a mounting base 1, a filter 2, a transmission module 3 for driving the filter 2 to rotate, and an electromagnetic module 4 for driving the transmission module 3; the mounting base 1 is provided with a mounting cavity 5; the electromagnetic module 4 is installed in the mounting cavity 5; the input end of the transmission module is installed in the mounting cavity 5 and is connected to the output end of the electromagnetic module 4; the output end of the transmission module passes through the mounting base 1 and is fixedly connected to the filter 2; a stop 7 adapted to the filter is provided on the top of the mounting base 1.
[0023] In this embodiment, the headlight color-changing mechanism mainly consists of a mounting base 1, a filter 2, a transmission module 3, and an electromagnetic module 4. During operation, the electromagnetic module 4 is energized to generate a magnetic field, which drives the transmission module 3 to rotate. In turn, the transmission module 3 drives the filter 2 to rotate, moving it to the position of the light source to block the light source and change its color. The overall structure is compact, simple, and easy to install. The use of an electromagnetic filter for light-changing operation effectively ensures the stability of the light-blocking plate and avoids vibration and noise. At the same time, the top of the mounting base 1 is also equipped with a baffle to limit the rotation angle of the filter, which can prevent the filter from shifting its position under the action of the magnetic field during use, thus failing to completely block the light source and affecting the light color-changing effect.
[0024] Furthermore, the transmission module 3 includes: a rotating shaft 31, a circular magnetic block 32, and a mounting housing 33; one end of the rotating shaft 31 is rotatably mounted in the mounting cavity 5; the mounting housing 33 is fixedly mounted on the rotating shaft 31 and located in the mounting cavity 5; the circular magnetic block 32 is fixedly mounted on the rotating shaft 31 in a relative state and located in the mounting housing 33; it also includes two limiting blocks 34; the two limiting blocks 34 are arranged opposite each other at the lower end of the outer side wall of the mounting housing 33; a limiting groove 8 is provided on the side wall of the mounting cavity 5.
[0025] In this embodiment, the transmission module 3 mainly consists of a rotating shaft 31, a circular magnetic block 32, a mounting housing 33, and two limiting blocks 34. When working, the electromagnetic module 4 is energized to generate a magnetic field. The magnetic field generated repels the like poles of the two semi-circular magnets of the rotating shaft 31 and attracts the unlike poles, thus generating a torsional magnetic force. The rotating shaft 31 rotates, driving the filter 2 to rotate. When the filter 2 rotates and blocks the headlight source, the headlight color changes. The structure is stable and easy to install.
[0026] Furthermore, the electromagnetic module 4 includes: two coils 41, two magnetic conductors 42, and two conductive conductors 43; one end of each magnetic conductor is disposed opposite to the other side of the mounting housing 33; the two coils 41 are respectively wound around the other ends of the two magnetic conductors 42; the two coils 41 and the two magnetic conductors 42 are all installed in the mounting cavity 5; one end of each conductive conductor 43 passes through the mounting base 1 and is electrically connected to the two coils 41 respectively, and the other end is placed outside the mounting base 1.
[0027] In this embodiment, the electromagnetic module 4 mainly consists of two coils 41, two magnetic conductive elements 42, and two conductive elements 43. The magnetic conductive element 42 is an iron core. One coil 41 is matched with one magnetic conductive element 42 and one conductive element 43 to form an electromagnetic coil 41 group.
[0028] Furthermore, the outer wall of the mounting base 1 is symmetrically provided with two hanging ears 6; specifically, by providing two symmetrical hanging ears 6, it is convenient to install the vehicle headlight color-changing mechanism.
[0029] Optionally, the mounting base 1 includes an upper cover 11 and a lower cover 12; the upper cover 11 and the lower cover 12 are engaged with each other to form the mounting cavity 5.
