In this embodiment, a seat number plate logo is provided on the second lampshade 1005, and the seat number glows on the second lampshade 1005 through the internal second light-emitting component 1004; on the other hand, other styles of seat numbers or pattern styles can also be made on the second lampshade 1005 as required to meet different needs.

[0039] The upper part of the handrail profile 10 is a third light-emitting area 1006, in which a third light-emitting component 1007 is installed, and a third lampshade 1008 is installed on the outside, so that the light of the third light-emitting component 1007 inside can be irradiated through the third lampshade 1008 to meet the needs of lighting or color display. In other examples, the handrail profile may not be installed with a light-emitting component here, but the lampshade may be made of different colors to further meet different needs.

[0040] The present invention also provides an assembly method for a multifunctional passenger car luggage rack. For the basic version, please refer to Fig.16 and Fig.17 , including the following steps: Step A: First, insert one side of the air duct plate 1 into the air duct plate insertion groove 303 of the side window profile 3, then abut and position the intermediate profile 1 6 against the first abutment groove 103 on one side of the bottom of the air duct plate 1, connect and fix the intermediate profile 1 6 to one side of the bottom of the air duct plate 1 by rivets, abut the intermediate profile 2 11 against the second abutment groove 104 on the other side of the bottom of the air duct plate 1, connect and fix the intermediate profile 2 11 to the other side of the bottom of the air duct plate 1 by rivets, finally overlap the overlapping portion 102 of the air duct plate 1 on the cantilever boss 405 of the top profile 4, and connect and fix the air duct plate 1 to the top profile 4 by rivets; Step B: The built-in hanger 8 is connected and fixed by bolts and rivets to the head 801 and the top profile 4, the tail 802 and the side window profile 3, the front leg 803 and the air duct plate 1 and the middle profile 1 6, and the rear leg 804 and the air duct plate 1 and the middle profile 2 11; Step C: The Z-shaped flange structure 202 on one side of the luggage board 2 is inserted into the 7-shaped groove structure 601 of the intermediate profile 1 6, and the luggage board 2 is connected and fixed to the intermediate profile 1 6 by rivets; the sink structure 203 on the other side of the luggage board 2 is abutted against the inverted L-shaped structure 1001 of the handrail profile 10, and the luggage board 2 is connected and fixed to the handrail profile 10 by rivets; Step D: The external hanger 9 is aligned with the second opening structure 401 of the top profile 4 and the third T-shaped slide groove structure 1002 of the handrail profile 10 through the mounting holes arranged above and below, and is connected and fixed thereto using T-shaped bolts; Step E: After the luggage rack structure is installed, it needs to be installed on the vehicle body frame 5. The multiple waist-shaped side free-of-matching drill holes 302 and the waist-shaped top free-of-matching drill holes 402 pre-opened in the side window profile 3 and the top profile 4 are aligned with the pre-set embedded nuts on the vehicle body frame 5. Use bolts to connect and lock with the pre-embedded nuts on the vehicle body frame 5 through the free-of-matching drill holes in turn. At this point, the entire luggage rack is fixedly installed on the vehicle body frame.

[0041] But if you need to expand, please refer to Fig.18and Fig.19 , just replace the extended top profile and extended armrest profile. The difference between the extended top profile and the basic luggage rack is that the top profile can have luminous parts or lampshades of different colors, and the armrest profile can also have luminous parts or backlit seat numbers or other backlit patterns, etc. Of course, in other instances, different functional states can also be selected and used to make different combinations to meet customers' different cost, color, luminous requirements, etc.

[0042] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
