The vehicle luggage rack assembly provided by the application can be applied to vehicles, including buses, rail trains and the like, and the public vehicles often need to carry a plurality of passengers at one time. The most common public transportation means is buses running along fixed routes in cities. The luggage rack structure will be specifically explained with reference to the drawings.
Referring to fig. 1, the present application provides a vehicle luggage rack assembly including an air duct structure 100, a luggage carrier 200. The air duct structure 100 is provided with an air duct, and a plurality of air duct openings are arranged at intervals along the extending direction of the length of the air duct structure. The luggage carrier 200 is disposed at one side of the air duct structure 100 and is disposed to extend in the same direction as the air duct structure 100. The duct structure 100 is configured to extend along a front-rear direction of a vehicle cabin, and has a plurality of air outlets arranged at different positions. A luggage carrier 200 is provided at a side of the duct structure 100, and the luggage carrier 200 may be used for placing and carrying articles. Line Li Tuojia of the present application is leather covered.
Referring to fig. 2 and 3, the luggage carrier 200 includes a profile strip 210, an upper leather layer 220, a lower leather layer 230, and a foaming layer 240. The profile strips 210 are arranged at both side edge positions of the luggage carrier 200 in the length extension direction. The upper leather layer 220 is used to construct the upper structure of the luggage carrier 200. The lower leather layer 230 is used to construct the lower structure of the luggage carrier 200. The foaming layer 240 is filled in an inner space defined by the upper leather layer 220, the lower leather layer 230, and the profile strips 210 at both side edge positions. At the edge positions of both sides of the luggage carrier 200, the material of the foaming layer 240 fills the internal structural space of the profile strip 210, so that the foaming layer 240 is directly combined with the profile strip 210 to form a connection relationship; the upper leather layer 220 covers the upper portion of the foaming layer 240 between the two side profile strips 210, and the lower leather layer 230 covers the lower portion of the foaming layer 240 between the two side profile strips 210.
Specifically, the main body of the luggage carrier 200 is constructed of a three-layer structure, i.e., an upper leather layer 220, a lower leather layer 230, and an intermediate foam layer 240. The upper leather layer 220 and the lower leather layer 230 are leather materials, which may be leather, regenerated leather, artificial leather, synthetic leather, for covering the upper and lower surfaces of the luggage carrier 200. Wherein the dermis is selected from cow leather, sheep leather and pig leather. The regenerated leather is produced by crushing waste leather and leather leftover of various animals and then blending chemical raw materials. The artificial leather is also called imitation leather or sizing material, is a generic name of artificial materials such as PVC and PU, and is manufactured by foaming or laminating films such as PVC and PU with various different formulas on a textile cloth base or a non-woven cloth base. Synthetic leather is a plastic product that mimics the composition and structure of natural leather and can be used as a substitute for natural leather. In addition, the foaming layer is made of foaming materials through a foaming molding process, and a honeycomb or porous structure is formed in the foaming molding process or the foaming polymer materials through the addition and reaction of a physical foaming agent or a chemical foaming agent.
In making the luggage carrier 200, the upper leather layer 220 is first laid on the surface of the upper mold and the lower leather layer 230 is placed on the surface of the lower mold. A foaming cavity is arranged between the upper die and the lower die and is used for forming foaming materials. Here, the upper leather layer 220 and the lower leather layer 230 are disposed at both upper and lower sides of the foaming cavity, and the foaming layer formed after foaming is directly combined with the leather layers at both upper and lower sides. Next, the profile strip 210 is placed at predetermined positions on both sides of the foaming cavity defined by the upper and lower molds, and the profile strip 210 is placed at edge positions on both sides of the luggage carrier 200, thereby forming an edge structure of the luggage carrier 200. Then, the foaming material is injected into the foaming cavity to perform a foaming reaction, so that the foaming material fills the space between the upper leather layer 220 and the lower leather layer 230 and expands to both sides to fill the inner structural space of the profile strips 210 at both sides, thereby directly combining the foaming layer 240 with the profile strips 210 to form a connection relationship, so as to manufacture the luggage carrier 200. After foaming, the foaming material fills the foaming cavity between the upper leather layer 220 and the lower leather layer 230, and thus the upper leather layer 220 and the lower leather layer 230, the profile strips 210 on both sides, and the foaming material form a unitary structure, i.e., row Li Tuojia. Finally, the luggage carrier 200 is coupled with the air duct structure 100 to form a vehicle luggage rack assembly.
It should be understood that in the above-described manufacturing process of the luggage carrier 200, the foaming material is filled in the foaming space formed by the upper leather layer 220 and the lower leather layer 230, and the both side profile strips 210 through the foaming process, so that the integral luggage carrier 200 can be formed. Therefore, the main body structure of the luggage carrier is formed by combining an upper leather layer, a lower leather layer, a foaming layer and a profile strip through a foaming process, and is an integrated structure, and only the integrated structure is required to be fixed on the air duct structure during assembly, so that the assembly process is effectively simplified. In addition, because the upper leather layer and the lower leather layer are directly covered on the surface of the foaming layer, the upper leather layer and the lower leather layer on the surface can be directly replaced and repaired independently, the maintainability is better, and the maintenance cost of the leather is lower. In addition, the upper leather layer, the lower leather layer, the foaming layer and the profile strips are combined more tightly, and compared with a structure that a plurality of parts are connected and fixed by adopting connecting pieces, the connecting gap is eliminated, so that the luggage carrier 200 is more stable in structure and is less prone to abnormal sound in a vehicle.
In addition, the profile strip 210 is a section of a profile, and the profile is an object with a certain geometry made of iron or steel or a material with a certain strength and toughness through processes of rolling, extrusion, casting, and the like. The material has a certain appearance size, a certain shape of section and certain mechanical and physical properties. In the embodiment of the present application, the profile strip 210 has a complex cross-sectional shape, as shown in fig. 2 and 3, and the complex cross-sectional profile is also called a special-shaped cross-sectional profile, which is characterized in that the cross-section has obvious convex-concave branches, and the profile strip 210 formed by the complex cross-sectional profile has a complex inner space, which can be used for filling foaming materials during foaming, so as to facilitate the combination with the foaming layer. The typical profile is an aluminum profile, and the profile strip 210 of the present application may be provided as an aluminum profile.
In the embodiment of the present application, the main structure of the air duct structure 100 may be made of a metal plate, and a plurality of air outlets are machined on the main structure for outputting cool and warm air.

Further, the covering member 250 is a thin-walled member, and a section perpendicular to the length thereof is a C-shaped structure, and the section bar 210 is clamped in the C-shaped structure and is detachably withdrawn. In particular, the cladding 250 may be a plastic cover that wraps the profile strip 210 inside, avoiding direct exposure to the outside. The cladding 250 is detachably engaged with the profile strip 210 and can be directly removed when detached.
Referring to fig. 4, limit end caps 270 are respectively provided at positions of both ends of the row Li Tuojia 200; the limit end cap 270 completely covers the end edges formed by the section bar 210, the upper leather layer 220, the lower leather layer 230, and the foaming layer 240. The limiting end caps 270 are installed at the end edges of the rows Li Tuojia to form a limiting structure at both ends of the luggage carrier 200, which can prevent the articles placed on the luggage carrier 200 from sliding down, and at the same time, the limiting end caps 270 can reinforce the main structure of the luggage carrier 200.
Referring to fig. 1 and 5, a plurality of connection structures 300 are arranged at intervals between the duct structure 100 and the luggage carrier 200 above the luggage carrier 200; the connecting structure 300 includes a first connecting leg 310 and a second connecting leg 320; the first connecting leg 310 is connected with the luggage carrier 200; the second connecting leg 320 is connected to the duct structure 100 above the luggage carrier 200. The connection structure 300 is provided between the duct structure 100 and the luggage carrier 200 for connecting the two. Referring specifically to fig. 5, the connecting structure 300 may be constructed from a number of components, including an inner connector and an outer housing structure. In one embodiment, the first connection leg 310 is connected to the luggage carrier 200 by a screw or bolt, and the second connection leg 320 is connected to the duct structure 100 by a screw or bolt. In other embodiments, the first connecting leg 310 and the luggage carrier 200 are attached together by gluing, and the second connecting leg 320 and the air duct structure 100 are attached together by gluing.

Step S702, the profile strip 210 is placed at predetermined positions on both sides of the foaming cavity defined by the upper mold and the lower mold.
In step S703, a foaming material is injected into the foaming cavity to perform a foaming reaction, so that the foaming material fills the space between the upper leather layer 220 and the lower leather layer 230 and expands to two sides to fill the internal structural space of the profile strip 210, thereby directly combining the foaming layer 240 with the profile strip 210 to form a connection relationship, so as to manufacture the luggage carrier 200.

Referring to fig. 8 and 9, the mold 400 includes an upper mold 410, a lower mold 420, and a foaming cavity 430 between the upper mold 410 and the lower mold 420. In manufacturing the vehicle luggage rack assembly using the above steps, the upper leather layer 220 is first laid on the surface of the upper mold 410, and the lower leather layer 230 is placed on the surface of the lower mold 420. Between the upper mold 410 and the lower mold 420 is a foaming cavity 430 for molding the foaming material. Here, the upper leather layer 220 and the lower leather layer 230 are disposed at both upper and lower sides of the foaming cavity 430, and the foaming layer formed after foaming is directly combined with the leather layers at both upper and lower sides. Next, the profile strip 210 is placed at predetermined positions on both sides of the foaming cavity 430 defined by the upper mold 410 and the lower mold 420, and the profile strip 210 is placed at edge positions on both sides of the luggage carrier 200, thereby forming an edge structure of the luggage carrier 200. Then, the foaming material is injected into the foaming cavity 430 to perform a foaming reaction, so that the foaming material fills the space between the upper leather layer 220 and the lower leather layer 230 and expands to both sides to fill the inner structural space of the profile strips 210 at both sides, thereby directly combining the foaming layer 240 with the profile strips 210 to form a connection relationship, so as to manufacture the luggage carrier 200. After foaming, the foaming material fills the foaming cavity between the upper leather layer 220 and the lower leather layer 230, and thus the upper leather layer 220 and the lower leather layer 230, the profile strips 210 on both sides, and the foaming material form a unitary structure, i.e., row Li Tuojia.

Therefore, the main body structure of the luggage carrier is formed by combining an upper leather layer, a lower leather layer, a foaming layer and a profile strip through a foaming process, and is an integrated structure, and only the integrated structure is required to be fixed on the air duct structure during assembly, so that the assembly process is effectively simplified. In addition, because the upper leather layer and the lower leather layer are directly covered on the surface of the foaming layer, the upper leather layer and the lower leather layer on the surface can be directly replaced and repaired independently, the maintainability is better, and the maintenance cost of the leather is lower.
