DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0031] There are two common ways to install the luggage rack assembly on the roof cover of the vehicle body. One is to open a mounting hole on the roof cover of the vehicle body, and the mounting bolts of the luggage rack assembly directly pass through the mounting hole and are locked and fixed on the inside of the vehicle body with nuts. This structure is easy to install and firmly installed, but the disadvantage is that the sealing performance of the mounting hole is high and the mounting hole is prone to leakage for a long time. Another way to install the luggage rack is to weld the luggage rack bracket directly on the roof cover, and the luggage rack assembly is installed on the luggage rack bracket of the vehicle body. The advantage of this structure is that there is no mounting hole on the roof cover and there is no risk of leakage. However, this type of luggage rack skeleton has mounting holes, and the luggage rack assembly is installed and fixed by mounting bolts through the mounting holes. The mounting holes of the assembly need to be blocked with installation hole covers. The common structure of the cover is to combine molecular material injection molded cover plate clips and aluminum alloy aluminum sheets into a small assembly, which is buckled into the mounting hole of the luggage rack assembly. The structure of the mounting hole cover plate clips and aluminum alloy aluminum sheets is often more complicated.

[0032] The utility model provides a car luggage rack structure, in which the luggage rack bracket is directly welded on the roof cover, and the luggage rack assembly is installed on the car body luggage rack bracket, which not only solves the problem of water leakage after a long time, but also improves the load and durability of the overall car luggage rack structure, and at the same time, has strong stability and is easy to maintain. In addition, this embodiment also provides a cover plate structure to solve the problem of complex cover plate structure.

[0033] The structure of the utility model will be further introduced below in conjunction with the accompanying drawings:

[0034] Example 1: Figure 1 , Figure 2 and Figure 3 As shown, a vehicle luggage rack structure includes a luggage rack assembly and a luggage rack mounting bracket 5. The luggage rack assembly is composed of a luggage rack frame 1 and a support 4. The support 4 is composed of a base 13 and a base cover 14.

[0035] The luggage rack mounting bracket 5 is in a "J" shape, which can improve the rigidity of the luggage rack mounting bracket 5 and ensure the stability of the connection structure. The two sides of the lower end surface of the luggage rack mounting bracket 5 are fixed to the roof cover by welding. Studs 7 are welded on the top of the luggage rack mounting bracket 5, and the support 4 is fixed to the luggage rack mounting bracket 5 through the studs 7. This installation and disassembly is convenient, and the luggage rack is installed on the roof luggage rack mounting bracket 5 without opening a luggage rack mounting hole on the roof, eliminating the risk of water leakage from the mounting hole on the roof.

[0036] like Figure 4 A support mounting hole 17 is provided on the support 4, and the support mounting hole 17 matches with the stud 7 on the top of the luggage rack mounting bracket 5. A rubber pad 6 is provided between the support 4 and the luggage rack mounting bracket 5, and the rubber pad 6 contacts the roof cover to play a role of buffering and sealing. At the same time, a plurality of base holes 16 are provided at the bottom of the base cover 14 constituting the support 4, and a plurality of protrusions 10 are provided on the side of the rubber pad 6 away from the roof cover. After the support 4 and the luggage rack mounting bracket 5 are installed, the protrusions 10 will extend into the base holes 16, so that the rubber pad 6 can be tightly attached to the roof cover and the support 4, further playing a role of buffering and sealing. The risk of damage to the luggage rack frame 1 can be reduced, thereby reducing the cost required to purchase and install the luggage rack, and its stability and safety can be improved. A small baffle 9 is provided under the base cover 14. After installation, the baffle 9 will contact the luggage rack mounting bracket 5. During driving of the vehicle, the baffle 9 prevents the luggage rack assembly from sliding laterally, thereby improving the stability of the luggage rack assembly, thereby greatly reducing the safety risks during driving, and reducing the possibility of items falling from the roof luggage rack and endangering other vehicles and pedestrians on the road.

[0037] Embodiment 2: The other structures in this embodiment are similar or identical to those mentioned in Embodiment 1, and therefore will not be described again. Figure 4 , Figure 5 As shown, the support 4 is composed of a base 13 and a base cover 14. The base cover 14 is a decorative cover, and the outside can be coated with a paint coating that is consistent with the color of the vehicle body, which can increase the durability of the base cover 14. The shape of the base 13 is gradually widened from one end to the other, and the base 13 is fixedly installed in the base cover 14. The material of the support 4 is aluminum alloy. This structure and material increase the rigidity of the luggage rack assembly and can bear a higher luggage rack load. Moreover, aluminum alloy has good weather resistance, and there is no risk of aging due to high temperature exposure on sunny days and changing seasons for the support 4 produced by polymer materials, which better meets the total load safety performance of the luggage rack. At the same time, a cylindrical round pin 15 is designed at the upper end of the support 4, which can facilitate the rapid assembly of the aluminum tube of the luggage rack.

[0038] like Figure 1As shown, the luggage rack frame 1 is a symmetrical structure and matches the curvature of the roof. The luggage rack frame 1 is a slender rod as a whole, and the material is aluminum, which can make the weight of the luggage rack assembly lighter and can also meet the required load-bearing capacity. Moreover, the shape of the long rod can also reduce the wind resistance and noise of the vehicle as much as possible during high-speed driving of the car, and can also reduce the fuel consumption of the car. A support 4 is installed at both ends of the luggage rack frame 1, namely the front and rear supports 4, and the outer layers of the front and rear supports 4 are respectively painted with paint coatings of different colors, making the luggage rack structure more beautiful. The front and rear supports 4 are fixedly mounted on the luggage rack mounting bracket 5 below them by studs 7. Luggage rack assembly mounting holes 2 are respectively opened at both ends of the luggage rack frame 1, and the luggage rack frame 1 is fixed to the support 4 by mounting bolts 8 through the luggage rack assembly mounting holes 2.

[0039] like Figure 6 As shown, near the luggage rack assembly mounting hole 2 on the luggage rack frame 1, a groove 18 is provided on the side close to the support 4. After installation and fixation, the cylindrical round pin 15 at the upper end of the support 4 will extend into the groove 18 on the luggage rack frame 1, which can make the connection between the luggage rack frame 1 and the support 4 more stable and make the luggage rack assembly structure more stable.

[0040] After the luggage rack frame 1 and the support 4 are installed and fixed, the luggage rack assembly mounting hole 2 is finally assembled by the cover plate buckle 12 and the cover plate. The common structure of the cover plate is to combine the molecular material injection cover plate buckle and the aluminum alloy aluminum sheet into a small assembly, which is buckled into the luggage rack assembly mounting hole 2. This structure is often more complicated. For example, one is that the aluminum sheet and the buckle are bonded with tape. This structure has the risk of the aluminum sheet falling off due to aging of the adhesive; the other structure is an aluminum sheet without a cover plate, and only a polymer material is used for the same color baking paint. This structure has the color difference between the frame and the cover plate due to the different materials, and it cannot be oxygen-anodized with the aluminum alloy frame at the same time. The surface of the luggage rack assembly is limited to baking paint, and it cannot be used as a matching bright aluminum alloy luggage rack for high-end models, and can only be used for matching mid- and low-end models. The cover plate structure 3 provided in this embodiment has a relatively simple process, is relatively convenient to assemble, is relatively stable to fix, and can achieve a uniform gap between the cover plate and the luggage rack assembly mounting hole 2, and the gap is small.

[0041] Embodiment 3: Other structures in this embodiment are similar or identical to those mentioned in the embodiment, and therefore will not be described again. Figure 6As shown, the cover plate buckle 12 described in this embodiment is arched as a whole. Such a shape can increase the bearing capacity of the luggage rack frame 1. Outward cover plate protrusions 21 are set on both sides of the cover plate buckle 12 to play a fixing role. Cover plate slots 22 are designed at the bottom of both ends of the cover plate buckle 12. This is for when the cover plate buckle 12 is installed in the luggage rack assembly mounting hole 2, pinch the two ends of the cover plate buckle 12 to apply pressure inward, and the bottom of the two ends will be compressed inward. At this time, the cover plate buckle 12 is pressed into the luggage rack assembly mounting hole 2, and the cover plate slots 22 at both ends of the cover plate buckle 12 can play a role of being stuck on the luggage rack frame 1, thereby improving stability. A card slot 20 is provided on the top of the cover plate buckle 12, and a buckle strip 19 is provided on one side of the cover plate. The cover plate is fastened by the card slot 20 and the buckle strip 19 to be fixed on the cover plate buckle 12. The material of the cover plate is consistent with that of the luggage rack frame 1, and the surface can be treated with the same process, such as surface anodizing or surface sunlight oxidation high-brightness machine. There will be no color difference due to the material and surface treatment process, which can reduce the number of regular maintenance and maintenance of the luggage rack, and it is not easy to rust and corrode; and the production process of the aluminum sheet is simple. The structure is simple to assemble, and the fixation is relatively firm and the sealing is strong. It can solve the problem of complex cover plate structure and uneven gap between the frame mounting holes. At the same time, the structure is also relatively simple to disassemble, which is convenient for maintenance and replacement of parts. Moreover, the overall weight of the automobile luggage rack structure is relatively light, and will not cause deformation to the roof.

[0042] The assembly method of a vehicle luggage rack of the utility model is as follows:

[0043] First, the luggage rack assembly is installed. Bolts are installed at both ends of the luggage rack frame 1 through the luggage rack assembly mounting holes 2 to connect and fix with the front and rear supports 4. At the same time, the columnar round pin 15 at the upper end of the support 4 will extend into the groove 18 on the luggage rack frame 1 for auxiliary fixation.

[0044] Next, the luggage rack assembly mounting holes 2 set at both ends of the luggage rack frame 1 are assembled by the cover plate buckles 12 and the cover plate. Pinch the two ends of the cover plate buckles 12 and apply pressure inward, and the bottoms of the two ends will be compressed inward. At this time, the cover plate buckles 12 are pressed into the luggage rack assembly mounting holes 2, and the cover plate is fastened by the slots 20 and the buckle strips 19 and fixed on the cover plate buckles 12, covering the connection structure of the luggage rack frame 1 and the support 4, while ensuring that the gap is uniform and small.

[0045] Finally, both sides of the lower end surface of the "ji"-shaped luggage rack mounting bracket 5 are fixed to the roof cover by welding, and the welding positions correspond to the lower sides of the two end supports 4 of the luggage rack skeleton 1, which facilitates the installation and fixation of the support 4. After the luggage rack mounting bracket 5 is welded and fixed to the roof cover, a fixing rubber pad 6 is laid under the luggage rack assembly and pressed tightly against the roof cover. Then, the support mounting hole 17 on the support 4 is installed and fixed to the stud 7 at the top of the luggage rack mounting bracket 5. After installation, the small baffle 9 provided under the base cover 14 will contact the luggage rack mounting bracket 5, assisting in enhancing the stability of the luggage rack assembly. At the same time, the protrusion 10 provided on the side of the rubber pad 6 away from the roof cover will extend into the base hole 16 provided at the bottom of the base cover 14, enabling the rubber pad 6 to be pressed tightly against the roof cover and the support 4, further playing a role in buffering and sealing.

[0046] The beneficial effects brought by the technical solution of the present utility model are as follows: The base 13 is installed in the base cover 14, and such a structure increases the rigidity of the luggage rack assembly and can bear a higher luggage rack load; the support 4 is made of aluminum alloy, which has good weather resistance, and there is no risk of aging for supports made of polymer materials due to high-temperature exposure in sunny days and seasonal changes, improving the durability of the structure; the structure of the card slot 20 and the snap strip 19 provided between the cover buckle 12 and the cover, as well as the structural features of the cover buckle 12, are simple in assembly, firm in fixation, and strong in sealing performance, and can solve the problems of complex cover structure and uneven gaps of the skeleton mounting holes; at the same time, the material selection of the cover is the same as that of the luggage rack skeleton, and the surface can be treated by the same process, and the aluminum sheet production process is simple, which can solve the problem of complex cover structure; the cooperation between the cylindrical pin 15 on the base 13 and the groove 18 on the luggage rack skeleton 1, the cooperation between the small baffle 9 under the base cover 13 and the luggage rack mounting bracket 5, and the cooperation between the base hole 16 under the base cover 14 and the rubber pad 6 can improve the overall stability and load-bearing capacity of the luggage rack structure.

[0047] The above-described embodiments are only preferred solutions of the present utility model, and do not impose any form of limitation on the present utility model. There are other variations and modifications without exceeding the technical solutions described in the claims.
