[0028] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the profile structure for the EMU luggage rack of this embodiment includes an extruded profile 1, and the cross-sectional shape of the profile 1 includes a fixed section 11, a base section 12, a base section 2 13, and a hanging section 15 connected in sequence; the fixed section 11 is fixedly mounted on the bracket 2 of the luggage rack, and the hanging section 15 is hung and connected with the bracket 2 of the luggage rack; the base section 12 is equipped with an auxiliary light strip 4, and the base section 2 13 is equipped with a display board 3.

[0030] In this embodiment, the auxiliary light strip 4 and the display board 3 can be integrated and installed on the extruded, one-piece structure profile 1, which effectively simplifies the installation method and layout of the auxiliary light strip 4 and the display board 3 on the luggage rack and facilitates assembly; at the same time, the profile 1 can be rotated a certain angle relative to the bracket 2 to facilitate inspection and maintenance, and also facilitate disassembly and assembly.

[0031] The base section 12 is a U-shaped structure with its opening facing downward, and the auxiliary light strip 4 is mounted at the open end of the U-shaped structure. While the auxiliary light strip 4 is installed, the auxiliary light strip 4 can also be cleverly accommodated in the base section 12, effectively helping to maintain the beauty of the overall appearance.

[0032] A protrusion 121 and a protrusion 123 are respectively extended from the inner wall surfaces on both sides of the opening end of the base section 12, and a clamping portion 122 is formed between the protrusion 121 and the protrusion 123; the edges on both sides of the auxiliary light strip 4 are clamped into the corresponding clamping portions 122, so that the auxiliary light strip 4 can be conveniently and quickly assembled and disassembled on the base section 12.

[0033] The distance between the protrusions 121 on both sides of the base section 12 is smaller than the distance between the protrusions 123 on both sides. The protrusion 123 is closer to the opening end than the protrusion 121, so that the protrusion 121 can effectively limit the insertion depth of the auxiliary light strip 4, and the protrusion 123 is combined with the clamping part 122 to realize the clamping and fixing of the auxiliary light strip 4, and the protrusion 123 effectively prevents the auxiliary light strip 4 from escaping from the base section 12.

[0034] The two side surfaces constituting the protrusion 121 are both flat surfaces perpendicular to the inner wall surface of the opening, which effectively ensures the limitation of the insertion depth of the auxiliary light strip 4; the two side surfaces constituting the protrusion 2 123 are both inclined surfaces with an obtuse angle to the inner wall surface of the opening, which prevents the auxiliary light strip 4 from falling out and facilitates the inward clamping operation of the auxiliary light strip 4.

[0035] The outer wall surface on one side of the opening end of the base segment 12 is connected to and extended with the fixed segment 11, and the outer wall surface on the other side of the opening end of the base segment 12 is connected to and extended with the base segment 2 13; the opening end of the base segment 12 and the bottom surface of the fixed segment 11 are located on the same plane, and an obtuse angle structure is formed between the base segment 12 and the base segment 2 13; a corner portion 16 is formed between the end of the wall surface at the opening end of the base segment 12 and the base segment 2 13; while achieving reliable installation of the profile 1 and the bracket 2, it helps to ensure the aesthetics of the overall appearance after being installed on the luggage rack, and is convenient for the auxiliary light strip 4 to achieve its lighting and aesthetics, and is convenient for the display board 3 to be used for display and viewing.

[0036] The bracket 2 forms a mounting space 20 via an inverted L-shaped structure, one end of the L-shaped structure is fixed to the fixing section 11 , and the other end of the L-shaped structure is mounted to the mounting section 15 , thereby achieving integration and installation of the profile 1 on the bracket 2 .

[0037] like Figure 3As shown, a T-slot 21 is provided at the downward end of the bracket 2, and a T-block 5 is slidably arranged in the T-slot 21; the fixed section 11 is a double-layer structure, and the top surface of the upper layer of the fixed section 11 is attached to the plane 22 of the end surface of the bracket 2; a through hole 111 is provided through the lower layer of the fixed section 11, and the external fastener passes through the through hole 111 to lock the upper layer to the T-block 5, and the fastener is accommodated in the interior of the double-layer structure of the fixed section 11, so that the fixed section 11 of the profile 1 can be quickly fixed on the bracket 2, and it is convenient for disassembly, maintenance and replacement.

[0038] In this embodiment, the through hole 111 is a long groove arranged along the length direction of the profile 1, and / or a plurality of through holes 111 are arranged at intervals along the length direction of the profile 1, which is convenient for fastener locking through the through hole 111 and accommodating the fastener inside the fixed section 11 through the through hole 111.

[0039] The second base segment 13 is a double-layer structure. The outer bottom surface of the lower layer of the second base segment 13 is concave to form an inner concave portion 131. The inner concave portion 131 accommodates the display sign 3.

[0040] In this embodiment, the double-layer structure is arranged to effectively ensure the structural strength and stability of the base segment 13, and the reliability of installing the display sign 3 is guaranteed; and an inner recess 131 is provided for accommodating the display sign 3, so that a preset mounting effect can be achieved, so that the surface of the mounted display sign 3 is basically in the same plane as the bottom surface of the base segment 13 or is slightly convex or concave, which helps to improve and ensure the beautiful appearance.

[0041] In this embodiment, the display card 3 can be installed in the inner recess 131 by gluing, or by other means.

[0042] The hanging section 15 is a C-shaped structure with an opening facing downward, and both ends of the hanging section 15 extend inward to form a protrusion 1 151 and a protrusion 152 respectively, and the protrusion 1 151 is higher than the protrusion 152; the end of the hanging section 15 extending with the protrusion 1 151 is fitted and extends into the hanging groove 23 of the bracket 2, and the hanging groove 23 is an inverted L-shaped structure, and the inner bottom surface of the hanging groove 23 constitutes a concave arc structure 24 adapted to the protrusion 1 151.
