Suspension type projection arrangement

Technical Field

The utility model relates to a carpet lamp adjusting device technical field, in particular to suspension type projection arrangement.

Background

With the continuous development of automotive electronics, a high-grade carpet lamp is introduced into some high-end vehicles during design and use to create a luxurious feeling.

The carpet lamp can be arranged in pairs in the width direction of the vehicle body chassis, the displayed light visual effect is good, and a user can feel integral aesthetic feeling. The frontmost light point of the carpet light type can be defined as P1, and the endmost light point of the carpet light type can be defined as P2.

In order to ensure the symmetrical light vision of the two sides of the vehicle body, it is required to ensure that the light type tail-end light spots P2 of the carpet lights corresponding to the left and right sides of the chassis of the vehicle body can realize the symmetry in the driving direction of the vehicle. However, due to the manufacturing tolerance of the parts, the tolerance of the installation positioning holes and the matching tolerance of the chassis, the carpet lamp parts usually have a certain pitch angle, and the positions of the light type tail-end light points P2 of the carpet lamp are affected to a certain degree, so that the light types of the carpet lamps on the left side and the right side of the chassis of the vehicle body are asymmetrical, and the visual aesthetic feeling is damaged.

It should be noted that the light type end light point P2 corresponding to the carpet lamp installed on the vehicle chassis is very sensitive to the pitch angle of the carpet lamp components, for example: when the carpet light has a pitch angle of 0.88 deg., the resulting light pattern end point P2 will have a fluctuating distance of 2 meters in the direction of travel.

Based on the above-mentioned problem, therefore need adjust the position of carpet lamp, nevertheless because under daytime illumination, P2 point is unable to see clearly on subaerial, consequently the utility model discloses it is expected to obtain a projection arrangement to measure P2 point indirectly.
