[0023] Symmetrically arranged screw holes and streamlined slots that are easy to produce and process reduce manufacturing costs, making this bracket not only maintain high performance, but also have high cost performance. Finally, the design of lock catch connection enhances the rigidity and torsional resistance of the overall structure, making the bracket stable under heavy load or harsh weather conditions.

[0024] Lock catch is divided into key part and lock body part, and the two sides of the upper and lower shells are respectively provided with the fixing device and locking device of the lock body part. The fixing device and locking device of the lock catch can ensure the firm connection of the upper and lower shells, and enhance the stability of the overall structure. The lock catch design makes the installation and removal of the roof rack relatively simple, suitable for situations that require frequent handling of items. The lock catch design allows the roof rack to have adjustable, foldable, replaceable accessories, etc. to adapt to different sizes and shapes of items, providing more flexibility and convenience. The fixing device and locking device of the lock catch can be quickly locked and unlocked, improving the use efficiency.

[0025] The key part is a b-shaped pin, and the middle section of the protruding part is provided with a T-shaped block. The design of the b-shaped pin matching the T-shaped block can provide a more stable locking mechanism, ensuring that the roof support and the load remain fixed during vehicle driving, reducing the risk of loosening or falling due to bumps or sharp turns. The design of the b-shaped pin makes it easier for the operator to insert or pull out the pin, while the T-shaped block provides a mortise and tenon joint platform, making the locking and unlocking process more convenient and fast. The design of the b-shaped pin and the T-shaped block is simple and strong, reducing the need for maintenance and replacement due to wear and tear or damage, thereby reducing long-term maintenance costs.

[0026] The fixing device is a flat cuboid, one end of which is fixedly connected with the outer shell, and the end away from the outer shell is provided with a slot matched with the pin.

When disassembly or maintenance is required, the design of the flat cuboid fixing device allows the pin to be easily removed, facilitating maintenance and replacement.

[0027] The locking device is a convex-shaped step, which is slightly larger than the T-shaped block of the pin. The design of the convex-shaped step can ensure that the T-shaped block of the pin is completely embedded, providing a larger contact area, thereby increasing the stability and firmness of the locking device. Moreover, by slightly rotating the pin, the T-shaped block on the pin can be stuck in the convex-shaped step, making it difficult for the pin to accidentally come out, enhancing the safety of the entire locking system, especially in applications requiring high safety. The convex-shaped step design simplifies the operation, allowing the pin to be quickly and accurately inserted and locked, improving the convenience of operation.

[0028] Between the two shells, the locking device of one shell corresponds to the fixing device of the other shell. The design of the locking device of one shell corresponding to the fixing device of the other shell not only ensures that the two shells can be accurately aligned during assembly, achieving uniform and tight fit, but also significantly enhances the stability and durability of the overall structure. This precise correspondence simplifies the assembly process, reduces errors caused by improper operation, and improves assembly efficiency and production speed. In addition, this design improves the safety of the product during use, especially when carrying heavy objects or driving at high speed, ensuring the firmness and reliability of the connection point.

[0029] Reducing wear and tear due to improper assembly helps extend the product's lifespan, making maintenance and replacement easier as each locking and securing device can be quickly identified and operated. This design also enhances the overall appearance of the product, making the connection between the two housings more neat and aesthetically pleasing, increasing the product's market competitiveness.

[0030] The design's adaptability is another advantage, as it can adapt to different usage environments and conditions, maintaining good performance in high-temperature, low-temperature, or humidity-changing environments, ensuring product reliability. Additionally, precise correspondence helps reduce noise and vibration caused by improper connection, improving ride comfort and providing users with a better experience.

[0031] In mass production, this design reduces adjustments and rework during assembly, improving production line efficiency and reducing production costs. Overall, this design improves product functionality and safety while simplifying assembly, reducing maintenance costs, and enhancing overall performance and aesthetics, making it a solution with advantages in multiple aspects.

[0032] The inner surface of the housing is provided with an inner concave cross-shaped reinforcing rib. Designing an inner concave cross-shaped reinforcing rib on the inner surface of the housing not only significantly improves the structural strength and rigidity of the housing, enabling it to withstand greater external pressure and impact load, but also achieves this without adding extra material, effectively saving production costs and material usage. This reinforcing rib design also helps improve the flow characteristics of the plastic during injection molding, ensuring uniform cavity filling and reducing internal stress after molding, thereby reducing surface defects such as sink marks and shrinkage, improving product aesthetics and optical performance.

[0033] In addition, the inner concave cross-shaped reinforcing rib helps maintain the shape and dimensional stability of the housing in different temperature and humidity environments, reducing deformation caused by environmental changes, which is particularly important for products used in harsh environments. The reinforcing rib design also helps distribute and absorb forces acting on the housing, extending the product's lifespan and reducing maintenance and replacement frequency, thereby reducing long-term operating costs.

[0034] In terms of injection molding process, a reasonable reinforcing rib design can reduce wear on the mold, improving its durability and lifespan, which is an important consideration for mass production. At the same time, this design provides certain design flexibility, allowing engineers to adjust the position and shape of the reinforcing rib according to specific application requirements to adapt to different structural and functional requirements.

[0035] The connection between the two shells is provided with a certain gap. First, it reduces the interference problem caused by size deviation or manufacturing tolerance during assembly, ensuring smooth assembly. Second, this design provides a buffer space for external impact, enhancing the stability and durability of the overall structure and prolonging the service life of the product.

[0036] Reducing stress concentration is also an advantage of this design. The gap can disperse the force acting on the shell, reducing the risk of damage to the connection due to force concentration. Finally, the appropriate gap, combined with sealing materials, can significantly improve the waterproof and dustproof performance of the shell, which is particularly important for products used outdoors or in harsh environments, ensuring reliable operation of the equipment under various conditions. In summary, the design of a certain gap between the two shells is a comprehensive performance optimization design that improves the functionality and maintenance convenience of the product while enhancing the durability and environmental adaptability of the product.

[0037] As Figure 2 is the side view of the utility model, the fixing device connects the upper shell and the lower shell, and both shells are provided with streamlined grooves. The pin is inserted into the fixing device and can be locked by slight rotation.

[0038] The upper shell and the lower shell are tightly combined by the fixing device, and streamlined grooves are designed on both shells. This structure not only improves the overall aesthetics, but also has actual functional advantages. After the pin is inserted into the fixing device, it can be quickly locked by slight rotation. This mechanism greatly simplifies the user's operation process, making the installation and disassembly of the roof rack more efficient and convenient, especially suitable for situations where luggage or equipment needs to be frequently loaded and unloaded.

[0039] This design also significantly improves the safety of the roof rack, as the slight rotation locking mechanism ensures the tight combination between the pin and the fixing device, reducing the risk of accidental loosening of the rack during driving due to bumps or turns. The design of the streamlined grooves helps to disperse stress and reduce local stress concentration, thereby improving the durability and reliability of the shell, allowing the rack to withstand longer use and heavier loads.

[0040] In addition, the streamlined grooves also help to reduce air resistance during vehicle driving, which not only reduces wind noise and improves driving comfort, but also improves fuel efficiency, which is particularly important for long-distance travel and the growing environmental awareness today. The slight rotation locking mechanism also means that the friction between the pin and the fixing device is reduced, thereby prolonging the service life of these components.

[0041] Ease of maintenance is another advantage of this design, users can easily check and replace the pins or fixing devices without complex tools or technical, which greatly reduces the maintenance cost and time. In summary, this roof rack design with its fast locking mechanism, high security, durability, aesthetics, reduce noise and vibration, improve aerodynamic performance and easy to maintain, etc. Multiple advantages provide users with an efficient and reliable roof loading solution, meeting the dual needs of modern drivers for convenience and practicality.

[0042] As Figure 3 is a cross-section view of the utility model, a cross-shaped reinforcing rib is arranged near the screw hole for connecting with the roof cross. The lock buckle is divided into fixing device and locking device. The fixing device is used for connecting the upper shell and the lower shell, and a groove for installing the pin is formed on one side. The pin is installed in the groove and shaped as b. A T-shaped block is also arranged in the middle section. The locking device is provided with a convex-shaped step matched with it. In order to lock more conveniently, the convex-shaped step is slightly larger than the T-shaped block on the pin.

[0043] The cross-shaped reinforcing rib is ingeniously arranged near the screw hole. This reinforcing measure greatly enhances the structural strength of this area, effectively prevents the deformation or rupture caused by the pressure on the shell when tightening the connecting screw, thereby improving the stability and durability of the overall structure. This local reinforcing design detail reflects the attention to product durability and reliability, ensuring the firmness of the roof rack during long-term use.

[0044] The design of the lock buckle device is divided into fixing device and locking device. This separated design makes the lock buckle operation more simple and intuitive. The fixing device is used for connecting the upper shell and the lower shell, and a groove for installing the pin is formed on one side. The pin is designed in b shape. This unique shape not only provides additional stability, but also provides a precise matching point for the locking device with the T-shaped block arranged in the middle section. The locking device is designed as a convex-shaped step, which is slightly larger than the T-shaped block on the pin, ensuring that the pin can be firmly locked in place, preventing the pin from falling off due to vibration or impact during vehicle driving, greatly enhancing safety.

[0045] In addition, this design improves operational efficiency. Through the cooperation of the driving member and the tongue assembly, users only need to rotate the driving member to quickly release or lock the fixed object, avoiding the complex operation that may be required by traditional lock buckle devices, greatly improving operational efficiency. This fast-responding lock mechanism not only saves time, but also reduces the risk caused by improper operation, making the use of the roof rack more convenient and efficient.

[0046] In summary, the roof support design by increasing cross-shaped reinforcing ribs in key areas, and optimizing the locking device fixed and locking mechanism, not only enhances the structural strength and durability of roof support, but also improves the convenience and safety of operation.
