The carpet lights 103 are located outside the jack work area. The carpet lamp 103 projects a light image to the side rear of the vehicle body side, and the projected light image can cover an area of the vehicle body side 2200mm long and 280mm wide.

Referring to fig. 2a, 2b and 2c, a block diagram of a carpet lamp according to an embodiment of the present invention is disclosed, wherein fig. 2b discloses a sectional structure along a transverse direction of the carpet lamp module, and fig. 2c discloses a sectional structure along a longitudinal direction of the carpet lamp module. As shown in the figure, the light guide holder 201 extends along the Y direction, and the front end of the light guide holder 201 has a front positioning mechanism, and the front positioning mechanism is fixed to the a-pillar stiffener. The tail end of the light guide bracket 201 is provided with a tail positioning mechanism, and the tail positioning mechanism is fixed with the front floor. The light guide bracket 201 has a mounting groove 211 thereon, and the carpet light module 202 is fixed in the mounting groove 211. The mounting groove 211 extends towards the lateral direction of the light guide bracket 201, and the extending direction of the mounting groove 211 forms an angle with the X direction. When mounted to the vehicle body, the mounting groove 211 is directed to the outside of the vehicle body, and the front of the mounting groove 211 forms a light guide channel 212, the front end of the light guide channel 212 being open. Referring to fig. 2b, one side of the mounting groove has a positioning engaging groove 213, the other side of the mounting groove has a positioning engaging block 214, and the tail of the mounting groove has a positioning screw hole 215. With reference to fig. 2a, 2b and 2c, the front end of the carpet light module 202 forms a projection surface 221. One side of the carpet light module 202 has a positioning pin 222, and the positioning pin 222 is engaged with the positioning slot 213. The other side of the carpet lamp module 202 is provided with a positioning buckle 223, and the positioning buckle 223 is matched with the positioning fixture block 214.

Thus, the carpet light module 202 is fixed in the installation groove 211, and the carpet light module 202 is installed to the light guide bracket 201. When installed in place, the projection surface 221 of the carpet light module 202 is aligned with the light guide channel 212. Referring to fig. 2c, the length of the light guide channel 212 is 35-40mm, the light guide channel is a gradually enlarged conical structure, and the overall direction of the light guide channel is towards the outside of the vehicle body and slightly inclines downwards.

Fig. 3 discloses a structure in which a light guide bracket of a carpet light according to an embodiment of the present invention is mounted to an a-pillar stiffener and a front floor. Referring to fig. 2a and 3, the front positioning mechanism of the light guide holder includes a screw hole 216 and two

studs

217 and 218. Screw hole 216,

studs

217 and 218 are located at the forwardmost end of the light guide holder, and screw hole 216 is located between the two

studs

217 and 218. The A-pillar reinforcing plate 104 is provided with a positioning round hole 141, a positioning screw hole 142 and a positioning waist hole 143 in sequence. The positioning round hole 141 corresponds to one of the studs 217, the positioning screw hole 142 corresponds to the screw hole 216, and the positioning waist hole 143 corresponds to the other stud 218. When the installation is performed, the two

studs

217 and 218 pass through the positioning round hole 141 and the positioning waist hole 143, respectively, and are locked by nuts, and the screw 302 passes through the positioning screw hole 142 and the screw hole 216 and is tightened, so that the light guide bracket 201 is fixed to the a-pillar stiffener 104 by the front positioning mechanism. A post reinforcing plate 104 is provided with a positioning round hole and a positioning waist hole, and a stud matched with the positioning waist hole has higher degree of freedom, so that the installation and alignment are more convenient. With continued reference to fig. 2a and 3, the tail positioning mechanism is a long kidney hole 219. The front floor 105 has a positioning stud 151 thereon, and the positioning stud 151 passes through the long waist hole 219 and is locked by a positioning nut 303, so that the light guide bracket 201 is fixed to the front floor 105 by the rear positioning mechanism. Similarly, the long kidney holes are used to match with the positioning studs so as to have more freedom, and the positioning alignment is easier.

From the point of view of installation location, the carpet lights should be installed as far forward as possible in the vehicle to achieve a larger footprint, but it is also desirable to ensure that the tires do not touch the components of the carpet lights to cause damage during vehicle operation. The mounting location of the carpet light then needs to be kept at a safe distance from the front wheel cover and the tire envelope surface. Fig. 4 discloses a schematic view of the safety separation between the carpet light and the front wheel cover and the tire runout envelope according to an embodiment of the present invention. As shown in fig. 4, the safety interval includes:

dimension a: the distance between the front wheel cover and the tire jumping envelope surface is not less than the safety distance.

Dimension B: the thickness of the front wheel cover is not less than the safety thickness.

Dimension C: the minimum distance between the carpet lamp and the front wheel cover is not less than the safety distance.

In one embodiment, the safety distance is 5mm, i.e. both dimension a and dimension C are 5mm, and the safety thickness is 2mm, i.e. dimension B is 2 mm. In dimension C, the minimum spacing between the carpet light and the front wheel cover refers to the minimum spacing between the carpet light assembly, including the wiring harness, and the front wheel cover. Namely, the carpet lamp needs to consider the position of the connecting wire harness, and the distance between all components on the carpet lamp assembly including the wire harness and the front wheel cover is not less than 5 mm. The above dimensions, together, may also be calculated to provide a minimum 12mm spacing between the carpet light assembly, including the wiring harness, and the tire runout envelope. In fig. 4, a light guide bracket 201, a carpet light module 202, a wiring harness 203, a front floor 105, a front wheel cover 102, and a tire bounce envelope 106 are shown.

In the subsequent processes of maintenance, repair and the like of the vehicle, the jack is used and can extend into the bottom of the vehicle to jack the reinforcing rib of the jack to jack the vehicle. In order to avoid damage to the carpet lights during use of the jack, the carpet lights need to be located outside the jack work area. Fig. 5 illustrates a schematic position diagram of a carpet light and jack work area according to an embodiment of the present invention. Referring to fig. 5, the jack working area is: the point of the jack mark 107 of the side wall aligned on the jack reinforcing rib 106 is used as the center of a circle, the radius of the jacking block of the jack plus the safety margin is used as the radius, and the range of the formed circle is within the range. In fig. 5, the circle 108 indicated by the arrow is the jack working area, and the carpet light 103 needs to be arranged outside the circle 108. In one embodiment, the jacking block 109 of the jack has a radius of 60mm and the safety margin is 30-35mm, so the radius of the circle 108 is 90-95 mm.

Fig. 6 is a schematic view of a projection range of a carpet light according to an embodiment of the present invention. Referring to fig. 6, the carpet light projects a light image to the lateral rear of one side of the vehicle body, and the projected light image can cover an area of the one side of the vehicle body which is 2200mm long and 280mm wide.

The above-described embodiments are provided to enable persons skilled in the art to make or use the invention, and many modifications and variations may be made to the above-described embodiments by persons skilled in the art without departing from the inventive concept of the present invention, so that the scope of the invention is not limited by the above-described embodiments, but should be accorded the widest scope consistent with the innovative features set forth in the claims.
