Description

Technical Field

[0001] This utility model belongs to the field of automobile luggage rack technology, specifically a luggage rack structure. Background Technology

[0002] Car roof racks are typically installed horizontally, usually made of aluminum alloy, high-strength engineering plastics, or composite materials. They are secured to the body's sheet metal structure (or pre-embedded rails) using bolts, clips, or dedicated bases, ensuring a stable load-bearing capacity and serving to expand cargo space, provide decorative appeal, and optimize aerodynamics. To enhance practicality and aesthetics, roof racks often feature frosted or brushed finishes or rubber anti-slip mats, and can be paired with stainless steel / aluminum alloy decorative covers, combining practicality with a premium, sporty look for the entire vehicle.

[0003] In the past, the main structure of luggage rack products usually used a design with an aluminum tube in the middle and PA66 plastic injection molded parts at both ends and sprayed with paint. The overall shape was slightly disjointed and the strength was insufficient. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a luggage rack structure, comprising an aluminum tube, a gasket, and a pad. The aluminum tube is manufactured by extrusion molding, followed by cutting and bending processes. The shape of the aluminum tube is adapted to the shape of the vehicle body. The gasket is made of TPE soft rubber material and is injection molded. The pad has built-in screws and is made of PA6 material. The aluminum tube, gasket, and pad are snapped together.

[0005] Preferably, the gasket is provided with a first snap-fit ​​protrusion, and the aluminum tube is provided with a second snap-fit ​​protrusion, and the first snap-fit ​​protrusion and the second snap-fit ​​protrusion are snapped together.

[0006] Preferably, there are two of each of the first and second snap-fit ​​protrusions.

[0007] Preferably, the screw passes through the pad, and a screw hole is provided inside the aluminum tube. The pad has a through hole, and the screw passes through the through hole and is threaded together with the screw hole.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This luggage rack uses a one-piece aluminum tube molding process, which not only significantly improves mechanical strength but also makes the rack more aesthetically pleasing. At the same time, it is equipped with a full-length TPE material gasket, which makes it fit more tightly with the body sheet metal, improving assembly stability, structural coordination and sealing performance, resulting in superior overall quality. Attached Figure Description

[0010] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Depend on Figures 1-4 The present invention discloses a luggage rack structure, including an aluminum tube 1, a gasket 2, and a pad 3. The aluminum tube 1 is manufactured by extrusion molding and then by cutting and bending processes. The shape of the aluminum tube 1 is adapted to the shape of the vehicle body. The gasket 2 is made of TPE soft rubber material and is injection molded. The pad 3 has built-in screws and is made of PA6 material. The aluminum tube 1, gasket 2, and pad 3 are snapped together.

[0018] The gasket 2 is provided with a first snap-fit ​​protrusion 4, and the aluminum tube 1 is provided with a second snap-fit ​​protrusion 5. The first snap-fit ​​protrusion 4 and the second snap-fit ​​protrusion 5 are snapped together. There are two of each type of gasket. As shown in the figure, the first snap-fit ​​protrusion 4 and the second snap-fit ​​protrusion 5 at both ends abut against each other, which can fix the position of the gasket 2 and facilitate the assembly of the gasket 2.

[0019] The screw passes through the pad 3 and has a screw hole inside the aluminum tube 1. The pad 2 has a through hole, and the screw passes through the through hole and is threaded together with the screw hole. This not only fixes the pad 2, but also facilitates the connection of the device to the vehicle body through the fixation of the pad 3.

[0020] In the production process of this luggage rack, aluminum ingots are first extruded to obtain aluminum tubes with a specified cross-sectional shape, which are then cut to obtain semi-finished aluminum tubes of a specific length. Subsequently, a bending process is used to shape the aluminum tubes to fit the contours of the vehicle body. After electrophoresis treatment and three coats of paint (including base coat and clear coat), a single-piece aluminum tube body is finally formed. The TPE soft rubber pad 2 is made from TPE raw material particles through a single injection molding process, resulting in a soft and elastic texture. The PA6 material pad 3 is formed by embedding pre-installed screws into the mold and then performing a second injection molding process, resulting in a robust and reliable structure. Finally, the aluminum tube body, TPE soft rubber pad 2, and PA6 material pad 3 are assembled into a complete product using a snap-fit ​​structure. The TPE accessories adhere softly, ensuring a tight fit with the vehicle body panels and improving assembly stability; the three PA6 material pads 3 securely snap into the holes on the vehicle body panels, providing reliable fixing force and making assembly simple and quick.
