Technical Field
The invention relates to the field of automobile lamps, in particular to a folding type hidden floor illuminating lamp combined with an automobile side mark.
Background
With the vigorous development of the automobile industry, the modeling of automobiles becomes one of the main selling points of the competition of various automobile enterprises, and the atmosphere lamp is the hot product of the current modeling.
The atmosphere lamp outside the car produces the pattern through throwing light to the subaerial of door below to promote user's visual perception. The atmosphere lamp outside the vehicle usually comprises a carpet lamp, a marker lamp (namely LOGO lamp) and the like, is usually used on high-end luxury vehicle types in the past, is also assembled on some middle-end vehicle types along with the continuous aggravation of competition among vehicle enterprises, is more likely to become the standard matching of the vehicle in the future, and has great development potential. LOGO is an abbreviation of LOGO or trademark, and automobile LOGO plays a role in identifying and popularizing automobile manufacturers.
At present, the defect that scheme self exists about arranging of this kind of car atmosphere lamp, and be difficult to satisfy the user demand of two kinds of carpet lamps and LOGO lamp simultaneously, restricted the development of car atmosphere lamp.
Carpet lamp and LOGO lamp all have requirements to the scope, definition, luminance etc. of formation of image, and both require respectively to be different.
Fig. 1 shows the effect of a carpet light of the prior art arranged on a chassis, as shown in fig. 1, which is often arranged under the chassis or on a door sill in the prior art due to the large required imaging area and the large volume of the lamp head.
Because the LOGO lamp has higher requirements on imaging definition, the axis of a light cone in the prior art is nearly vertical to the ground, and the LOGO lamp is usually arranged inside a vehicle door or integrated in a rearview mirror.
Both of the above-described arrangements of atmosphere lamps have drawbacks.
The carpet light arrangement on the chassis has the following disadvantages:
1) the carpet lamp is easy to be stained, and the carpet lamp is difficult to clean after being stained;
2) the carpet lamp is low in position and is easily hit by the ground stone, and the property loss is caused by the damage of the lamp holder;
3) the position of the carpet lamp is overlapped with that of the jack, and if a user does not operate properly, the lamp head is easily damaged to cause loss;
4) the carpet lamp is low in position and easy to wade to cause loss;
5) the distance is nearer to ground, in order to guarantee sufficient irradiation area, has restricted the contained angle on carpet lamp and ground, has influenced the definition of formation of image, leads to the length that the pattern can clearly form an image and is less than the one third of pattern full length.
In order to obtain a better visual effect, the projection shape of the existing carpet lamp is mostly 'angel wing' as shown in fig. 1, even if the front and back directions of the vehicle are distorted, the carpet lamp still can present a better effect, but if all automobile models adopt similar patterns, the styles of the automobile lamps cannot be revealed, and the aesthetic fatigue of users is easily caused.
Fig. 2a shows the effect of a prior art carpet lamp arranged on a door sill, and fig. 2b is a partially enlarged view of the box portion of fig. 2a, and as shown in fig. 2a and 2b, a
The carpet lamp is arranged in the threshold, a large space needs to be reserved inside the vehicle threshold, but most vehicles are not provided with the plastic threshold at present, so that the application scene of the arrangement scheme is greatly limited.
At present, aiming at the defects of the carpet lamp arrangement scheme, the following compensation measures are provided:
1) a cleaning water gun is added beside the lamp holder to solve the problem of fouling;
2) the problem of distortion of an imaging pattern is solved by adopting a mode of combining a plurality of atmosphere lamps for imaging.
However, none of the above-mentioned compensation measures fundamentally solves the technical problems that the carpet lamp is easily damaged by the jack, the imaging effect is poor, and the carpet lamp is easily stained and damaged.
The defects existing when the LOGO lamp is arranged inside the vehicle door are as follows:
1) the interior space of the vehicle door is compact, so that the requirement on the size of the LOGO lamp is high;
2) only when the door is opened at a large angle, the imaging pattern can be completely displayed, and the light is completely shielded in the scenes that a user is about to get on the vehicle and the door of the vehicle is closed by the user.
The LOGO lamp is integrated in the rearview mirror and has the following defects:
1) the volume of the rearview mirror is increased, the wind resistance is increased, and the fuel economy is reduced;
2) rear view mirrors belong to the vulnerable parts of vehicles, in which too many elements are integrated, which will increase the costs of the later maintenance for the user.
In addition, the scheme of above-mentioned all carpet lamps and LOGO lamp is except self defect, all can't satisfy the demand of arranging of LOGO lamp and carpet lamp simultaneously, and the commonality is relatively poor.
