Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a roof rack. Background Technology

[0002] With the increasing number of outdoor car travel scenarios, roof racks, as key components for expanding cargo space and carrying outdoor equipment, are receiving more and more attention for their functionality and flexibility. Existing roof racks suffer from insufficient expandability, making it difficult to adapt to the installation of various outdoor equipment; poor ease of assembly and disassembly, as they are mostly disassembled as a whole, making partial maintenance or structural adjustments inconvenient; and a lack of user-friendly auxiliary design, resulting in a poor user experience. These issues fail to meet the diverse and convenient usage needs of consumers, and structural innovation and optimization are urgently needed. Therefore, we propose a new roof rack.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figure 1As shown, this utility model provides a roof rack, including: a support frame 1, two limiting seats 2, and a limiting frame 3 adapted to the support frame 1; the limiting frame 3 is detachably installed on the upper surface of the support frame 1; the bottom of the support frame 1 is provided with a plurality of connecting parts 4 for connecting with the roof bracket of the car; a plurality of crossbars 5 are equidistantly arranged on the inner side of the support frame 1 along the length direction of the support frame 1; a plurality of first expansion holes 6 are opened on the crossbars 5; the front end and rear end of the limiting frame 3 are... The support frame 1 is provided with an inwardly recessed clearance 7; two limiting seats 2 are respectively installed at the front and rear ends of the support frame 1, and the two limiting seats 2 are placed in the clearance 7 in a one-to-one correspondence; the limiting seats 2 are respectively fixedly connected to the limiting frame 3; at least one limiting block 8 is provided on the left and right edges of the support frame; the limiting block 8 abuts against the outer side of the limiting frame 3; the limiting frame 3 is a square structural frame formed by continuous bending of a round tube; several second expansion holes 9 are opened around the support frame 1.

[0019] In this embodiment, as Figure 1-2 As shown, there are four crossbars 5 and four limiting blocks 8. In other embodiments, the number of crossbars 5 and limiting blocks 8 can be increased or decreased according to the actual application. The four limiting blocks 8 are installed in pairs on both sides of the edge of the support frame 1. The support frame 1 and the crossbars 5 cooperate to form a bearing frame for the stroke foundation. Several first expansion holes 6 are opened on the crossbars 5 along their length, and second expansion holes 9 are set around the support frame 1 for connecting external tent brackets, ski racks, luggage nets and other expansion accessories. The expansion accessories can be quickly installed and disassembled through bolts, buckles and other adapter connectors 4, improving the functional expansion adaptability of the luggage rack. The limiting frame 3 is a square structure frame formed by continuous bending of round tubes, which can effectively ensure The structural strength of the limiting frame 3 is enhanced by the fact that the support frame 1 is a sheet metal frame. During assembly, the limiting frame 3 is detachably installed on the support frame 1 using screws, pins, and other connecting parts. The overall assembly forms a detachable upper tube and a lower sheet metal structure. The upper tube is connected to the support frame 1 via quick-release parts (using screws and pins to achieve locking, pin-type, or other assembly structures), and can be removed separately for flexible use of the upper space or partial maintenance. At the same time, the support frame 1 is equipped with a limiting seat 2 and a limiting block 8, which can further limit and fix the limiting frame 3, effectively strengthening its structural strength. When the limiting frame 3 is removed and the support frame 1 is used directly, items can be limited to meet the load-bearing requirements of items of different shapes, such as the placement of large, irregular equipment.

[0020] Further, the connector 4 includes: a fixing block 41 and a hook 42; one end of the fixing block 41 is provided with at least one elongated hole for screws to pass through; the fixing block 41 is adjustablely installed on the bottom of the support frame 1 through the elongated hole and the screw; the other end of the fixing block 41 is provided with a receiving cavity, and an arc-shaped structure 43 adapted to the hook is provided on the outer side of its bottom; the upper end of the hook 42 is provided with a mounting part adapted to the receiving cavity; the upper end of the hook 42 is fixedly connected to the fixing block 41 by screws; when the hook 42 and the fixing block 41 are connected, the mounting part is placed in the receiving cavity.

[0021] In this embodiment, as Figure 1-2 As shown, the arc-shaped structure 43 on the fixing block 41 cooperates with the hook to form a roof bracket for clamping the car, which can clamp and position the roof rack during installation, making the assembly of the roof rack convenient and effectively improving its assembly strength.

[0022] Furthermore, at least one power handle 10 is installed at the front end and the rear end of the support frame 1, respectively.

[0023] In this embodiment, as Figure 1 As shown, there are four power handles 10, which are symmetrically arranged in pairs at the front and rear ends of the support frame 1. The handles are fixed to the support frame 1 by welding or detachable connection. The material is a lightweight high-strength alloy, which makes it easy for users to install / remove the luggage rack and take items off the roof, improving the convenience and safety of operation and filling the gap in the humanized design of similar products in the market.

[0024] Furthermore, the limiting seat 2 is provided with a hollow structure 11; specifically, by providing the hollow structure 11, its overall weight is reduced while ensuring its structural strength.

[0025] This utility model discloses a roof rack with multiple expansion holes, supporting the connection of various outdoor equipment and adapting to diverse scenarios such as camping, skiing, and off-roading, thereby enhancing the vehicle's outdoor expansion capabilities. It employs a detachable assembly structure with an upper limiting frame and a lower support frame, facilitating repair and replacement of localized faults and allowing for structural switching based on item type and usage scenario. For example, a pure platform mode can be used to accommodate large equipment, enhancing flexibility. The addition of handrails provides convenient support for user operation, reducing the difficulty and safety risks of rooftop operation and optimizing the user experience.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
