Description

Technical Field

[0001] This utility model relates to the field of roof rack technology, specifically a combined aluminum alloy car roof rack. Background Technology

[0002] A roof rack, also known as a roof luggage rack, is a device installed on the roof of a vehicle for placing items.

[0003] Existing roof racks are mostly fixed frames whose X and Y axes cannot be freely deformed. Due to their fixed shape, they are difficult to fully adapt to items of different sizes and shapes. Even those frames that can deform have certain limitations. To achieve deformability, these racks usually have complex mechanical structures, such as foldable joints and telescopic components. These complex structures not only increase manufacturing costs and product weight but may also reduce the overall stability and reliability of the structure. During long-term use, these structures are prone to loosening and wear, affecting the normal use of the rack. For large, irregularly shaped items, such as skis and surfboards, they may not be properly secured, causing them to wobble during transport and potentially damaging the items or the vehicle. Therefore, we propose a modular aluminum alloy roof rack to solve these problems. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A modular aluminum alloy car roof rack includes two first fixed frames and two second fixed frames. V-shaped seats are fixedly connected to both ends of the first fixed frames, and the V-shaped seats are slidably connected to the second fixed frames. Motion grooves are formed on the adjacent end faces of the two second fixed frames. Motion seats are housed within the motion grooves and are slidably connected to the groove walls. A connecting window is formed on the side of the motion groove near the first fixed frames. A threaded roller is sleeved in the middle of the motion seat, and the motion seat is fixedly connected to the threaded roller. The end of the threaded roller away from the motion seat extends through the connecting window and the V-shaped seats to the first fixed frames. The threaded roller is threadedly connected to the V-shaped seats. Multiple mounting grooves are formed on the side of the motion seat near the first fixed frames. Telescopic springs are housed within the mounting grooves. A sliding cylinder is fixedly connected to one end of each telescopic spring. An assembly groove is formed on the end of the sliding cylinder away from the motion seat, and a guide wheel is installed inside the assembly groove.

[0007] Preferably, the first fixing frame and the second fixing frame are distributed perpendicular to each other.

[0008] Preferably, the V-shaped seats at both ends are symmetrically distributed along the axis of the first fixing frame, and the side of the V-shaped seat away from the first fixing frame is in contact with the second fixing frame.

[0009] Preferably, the second fixing frame is provided with pillow seats at both ends, and a plurality of pins are installed on the surface of the pillow seats, and the pillow seats are connected to the second fixing frame through the pins.

[0010] Preferably, one end of the telescopic spring is fixedly connected to the bottom of the mounting groove cavity.

[0011] Preferably, the sliding cylinder is placed in the mounting groove, and the sliding cylinder is slidably connected to the wall of the mounting groove.

[0013] Preferably, a plurality of pads are fixedly connected to the side of the motion seat near the first fixed frame, and the plurality of pads are distributed between the plurality of guide wheels.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] The roof rack of this utility model consists of two mutually perpendicular first fixed frames and a second fixed frame. The first fixed frame has V-shaped seats symmetrically distributed at both ends, which are slidably connected to the second fixed frame. The second fixed frame has headrests at both ends fixed by pins, and a slidingly connected motion seat is built into the end face motion groove. A threaded roller sleeved on the motion seat passes through the connecting window, the V-shaped seat, and the first fixed frame, and is threadedly connected to the V-shaped seat, serving as a "control hub." Rotating it allows the structure to flexibly deform and precisely lock according to the shape of the items.

[0016] A mounting groove is provided on the side of the moving seat near the first fixed frame, with an internal telescopic spring connecting to the sliding cylinder. The guide wheel at the end of the sliding cylinder contacts the wall of the moving groove, and together with the shim in between, a sophisticated friction-reducing and stabilizing system is formed. First, fix the first fixed frame to the longitudinal luggage rack on the roof, then assemble the second fixed frame and fix the headrest with pins.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figures 1-5As shown, this utility model provides a combined aluminum alloy car roof rack, including two first fixed frames 1 and two second fixed frames 2. The first fixed frames 1 and the second fixed frames 2 are perpendicular to each other. V-shaped seats 101 are fixedly connected to both ends of the first fixed frames 1. The V-shaped seats 101 are symmetrically distributed along the axis of the first fixed frames 1. The side of the V-shaped seats 101 away from the first fixed frames 1 contacts the second fixed frames 2. The V-shaped seats 101 and the second fixed frames 2 are slidably connected. Pillow seats 201 are provided at both ends of the second fixed frames 2. Multiple pins 202 are installed on the surface of the pillow seats 201. The pillow seats 201 are connected to the second fixed frames 2 through the pins 202. The end faces of the two second fixed frames 2 that are close to each other are provided with movement grooves 203. The device includes a built-in motion seat 204, which is slidably connected to the wall of a motion groove 203. A connecting window 205 is provided on the side of the motion groove 203 near the first fixed frame 1. A threaded roller 206 is fitted into the middle of the motion seat 204. Multiple through holes 102 are provided in the middle of both the first fixed frame 1 and the second fixed frame 2. The motion seat 204 is fixedly connected to the threaded roller 206. One end of the threaded roller 206, away from the motion seat 204, extends through the connecting window 205 and the V-shaped seat 101 to the first fixed frame 1, where it is threadedly connected to the V-shaped seat 101. This design makes the threaded roller 206 act as a precise "control hub," allowing the motion seat 204 to slide within the motion groove 203 by rotation, utilizing the mechanical properties of the thread. Since the first fixed frame 1 and the second fixed frame 2 are interconnected through the V-shaped seat 101, the moving seat 204, and the threaded roller 206, when the threaded roller 206 rotates, it can drive the entire structure to deform and combine freely in the X and Y axis directions. This through-type design eliminates the limitations of traditional fixed-point connections, allowing the threaded roller 206 to stop at the most suitable position according to actual needs, thereby precisely locking the base and perfectly adapting to vehicle-mounted items of different sizes and shapes.

[0026] Furthermore, multiple mounting slots 207 are provided on the side of the motion seat 204 near the first fixed frame 1. A telescopic spring 208 is built into each mounting slot 207. One end of the telescopic spring 208 is fixedly connected to the bottom of the inner cavity of the mounting slot 207, and the other end is fixedly connected to a sliding cylinder 209. The sliding cylinder 209 is placed inside the mounting slot 207 and slidably connected to the wall of the mounting slot 207. An assembly slot 210 is provided on the end of the sliding cylinder 209 away from the motion seat 204. A guide wheel 211 is installed inside the assembly slot 210. The side of the guide wheel 211 away from the motion seat 204 contacts the wall of the motion slot 203. Multiple gaskets 212 are fixedly connected to the side of the motion seat 204 near the first fixed frame 1. The multiple gaskets 212 are distributed between the multiple guide wheels 211. Multiple mounting slots 207 are carefully arranged on the side of the motion seat 204 near the first fixed frame 1, with telescopic springs 208 built into them. One end of the telescopic spring 208 is fixed to the bottom of the inner cavity of the mounting groove 207, and the other end is connected to the sliding cylinder 209. The sliding cylinder 209 slides in contact with the wall of the mounting groove 207, thus forming a highly elastic buffer structure. The guide wheel 211 in the mounting groove 210 at the end of the sliding cylinder 209 is in constant contact with the wall of the moving groove 203. During the adjustment of the shape of the rack and the movement of carrying heavy objects, the guide wheel 211 rolls, which greatly reduces the friction between the moving seat 204 and the moving groove 203, making the deformation operation smoother. At the same time, the shims 212 distributed between the guide wheels 211 play a role in the tightened state. They are in close contact and fixed, which not only enhances the structural stability but also avoids damage to the rack due to excessive shaking.

[0027] Working Principle: When installing the cargo rack, firstly, the first fixed frame 1 is fixedly connected to the longitudinal luggage rack on the car roof. Then, the second fixed frame 2 is initially assembled with the first fixed frame 1 via the V-shaped seat 101. At this time, the pins 202 on the headrest 201 ensure that both ends of the second fixed frame 2 are stable. Subsequently, according to the size and shape of the items to be carried, the threaded roller 206 is rotated. The rotation of the threaded roller 206 causes the moving seat 204 to slide within the moving groove 203, driving the second fixed frame 2 to flexibly adjust its position along the X and Y axes to achieve precise adaptation. During the movement, the guide wheel 211 rolls under the cooperative support of the telescopic spring 208 and the sliding cylinder 209, continuously reducing frictional resistance and ensuring smooth deformation of the entire structure. Once the position is determined, the threaded roller 206 is tightened, and the self-locking property of the thread is used to firmly lock all components, and the gasket 212 fits tightly, making the cargo rack a stable and reliable roof support platform.

[0028] With its unique X and Y axis flexibility, this rack can accommodate a variety of items, from long, narrow skis and large luggage bags to irregularly shaped outdoor gear, greatly expanding the range of items that can be carried in a vehicle. The through-type threaded roller 206 design breaks through traditional connection limitations, allowing for locking at any ideal point. Combined with the shim 212 for enhanced stability, it ensures that items on the rack remain perfectly still even at high speeds and on bumpy roads, guaranteeing driving safety. The friction-reducing system, consisting of the telescopic spring 208, sliding cylinder 209, and guide wheel 211, allows for easy and flexible adjustment of the rack's shape, making installation quick and easy, even for users with less strength. Made of aluminum alloy, it combines lightweight design with high strength, resisting rust and corrosion. Its ingenious and rational structural design effectively withstands impacts and vibrations from daily use, extending the rack's lifespan and providing car owners with a long-term, high-quality roof-mounted cargo service.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
