With the improvement of people's living standards and the diversification of travel needs, the usage scenarios of automobiles are becoming increasingly diverse, and the demand for loading space is constantly increasing. Roof racks, as tools that can add extra loading space on the top of a vehicle, have emerged to meet this need. They allow people to carry more luggage or other items when traveling, greatly improving the practicality and functionality of automobiles and meeting the needs of various scenarios such as long-distance travel and outdoor adventures. They have been widely used and developed in the automotive industry.

[0003] A roof rack reference in related technologies Figure 6 As shown, it includes a base 2 and a crossbar 1. There are two bases 2, which are respectively fixed to both sides of the roof structure. The crossbar 1 is fixed between the two bases 2 to realize the installation of the roof rack. Furthermore, the base 2 in the related technology includes a base plate 21 and a column 22. The base plate 21 is attached to the roof surface to provide support. The column 22 has a square structure and is perpendicular to the base plate 21. The bottom of the column 22 is fixed to the middle of the base plate 21 to realize the assembly of the base 2.

[0004] The aforementioned technologies have the following drawbacks: the square-shaped columns in the technologies are concentrated in the middle of the base plate, and the stress area is relatively small. Therefore, in actual use, especially when loading goods for a long time, the middle of the base plate is prone to warping on both sides under the pressure of the bottom of the columns, which needs to be improved. Utility Model Content

[0005] In order to improve the force exerted by the uprights on the base plate in related technologies and to improve the problem of the base plate edges easily lifting, this application provides a roof rack.

[0038] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0039] This application mainly adopts a trapezoidal prism column to increase the contact area with the base plate, which improves the force exerted by the column on the base plate and reduces the warping of the base plate edge. The following is a further detailed description of this application. Example

[0040] Reference Figure 1 and Figure 2 The roof rack provided in this application includes a crossbar 1 and a base 2 at the end of the crossbar 1. The crossbar 1 is connected to the base 2 on both sides. In addition, a locking cover 3 is provided at the end of the crossbar 1. The locking cover 3 is used to cover the connection between the crossbar 1 and the base 2, and the locking cover 3 is connected to the base 2. Through the cooperation of the crossbar 1 and the base 2, the roof rack can be installed on the roof of the car and the loading of items can be realized. This structural design allows the roof rack to be stably installed on the roof of the car, providing support for luggage and other items.

[0041] Specifically, the base 2 includes a connected base plate 21 and a column 22, with the column 22 connected to the crossbar 1. The base plate 21 is typically made of metal, such as aluminum alloy, which has good strength and corrosion resistance. It is rectangular in shape and fits snugly against the roof surface, providing stable support for the entire roof rack. The outer edge of the column 22 has a trapezoidal prism structure. This structure can be integrally formed by bending sheet metal. In other embodiments, the column 22 can also be a frustum-shaped structure or similar structure with a large base area and a small top area to replace the trapezoidal prism, achieving the same effect of increasing the contact area with the base plate 21. In this embodiment, the outer edge of the column 22 has a trapezoidal prism structure with a base area larger than the top area, increasing the contact area between the column 22 and the base plate 21. The edge is closer to the edge of the base plate 21, resulting in a larger downward pressure range from the column 22 on the base plate 21 during actual load-bearing, making it less likely for the edge of the base plate 21 to warp, thereby improving the stability and service life of the roof rack.

[0042] Reference Figure 3 and Figure 4 Furthermore, the column 22 includes an end plate 221 and two side plates 222, with the side plates 222 located on both sides of the end plate 221. Both the end plate 221 and the side plates 222 can be made of stainless steel sheet with a certain thickness to ensure strength. The plane of the end plate 221 is perpendicular to the plane of the base plate 21, and the plane of the end plate 221 is perpendicular to the length direction of the crossbar 1. The column 22 serves to connect the crossbar 1 and support the object. The top of the side plate 222 is inclined towards the inside of the column 22, and the inclination angle can be adjusted according to the actual design. This inclination makes the structure of the column 22 more stable and also better disperses pressure. In addition to the inclined, straight side plate 222, other embodiments can also use an arc-shaped side plate 222 instead, which can also achieve the effect of pressure dispersion and structural stability.

[0043] The base plate 21 is equipped with two connecting plates 211. The connecting plates 211 can be made of the same material as the base plate 21 and are integrally formed on the base plate 21 by welding or stamping. The connecting plates 211 and their corresponding side plates 222 are parallel and fitted together, making the connection between the column 22 and the base plate 21 tighter and more stable. The connecting plates 211 and the side plates 222 are detachably connected by bolts and nuts. The bolts and nuts can be made of high-strength carbon steel to ensure the reliability of the connection. During installation, the bolts are first passed through the pre-drilled holes in the connecting plates 211 and the side plates 222, and then the nuts are tightened to complete the connection. This detachable connection method facilitates installation and disassembly, and also facilitates later maintenance and replacement of parts.

[0044] Reference Figure 2 and Figure 5A lock cover 3 is installed on the outer side of the pillar 22. The lock cover 3 can be made of plastic and has a certain degree of waterproof and dustproof function. The lock cover 3 is equipped with a lock cylinder 31, and the pillar 22 is correspondingly equipped with a key hole 32, through which the lock cylinder 31 passes. The lock cylinder 31 and the key hole 32 can be matched with a common mechanical lock structure, and the opening and closing of the lock is controlled by turning a key, which enhances the security of the roof rack and prevents unauthorized opening.

[0045] Reference Figure 3 The crossbar 1 has a reinforcing rib 11 inside. In this embodiment, the reinforcing rib 11 is vertically arranged and can be integrally formed inside the crossbar 1. In other embodiments, the reinforcing rib 11 can also be cross-shaped, star-shaped, etc., which can enhance the strength and rigidity of the crossbar 1 and improve its load-bearing capacity. The crossbar 1 has a mounting hole 12 inside. In this embodiment, the mounting hole 12 is formed through the gap between two reinforcing ribs 11. The column 22 has an insert 23 on the side near the crossbar 1. The insert 23 can be integrally formed with the column 22, also formed by bending sheet metal. The insert 23 is fitted into the mounting hole 12 to achieve the initial connection between the column 22 and the crossbar 1, and can be finally fastened with bolts.

[0046] Reference Figure 3 A mounting groove 13 is provided at the top of the inner wall of the crossbar 1. The mounting groove 13 can be made of aluminum alloy and is fixed to the top of the inner wall of the crossbar 1 by welding, snap-fitting, or profile stretching and extrusion. The bottom of the mounting groove 13 fits against the top wall of the insert block 23, further enhancing the stability of the connection between the column 22 and the crossbar 1. The mounting groove 13 and the insert block 23 are detachably connected by bolts and nuts. A notch is provided on the top wall of the crossbar 1 above the mounting groove 13 to facilitate the installation and removal of bolts. A sealing strip 14 is provided inside the mounting groove 13. The sealing strip 14 can be made of rubber and has good waterproof and sealing performance, reducing the entry of rainwater into the crossbar 1 and protecting the internal structure.

[0047] In addition, the inner sidewall of the mounting groove 13 is set perpendicular to the inner bottom wall, which makes it easier to install the T-screws for expansion.

[0048] The implementation principle of this embodiment is as follows: The roof rack in this embodiment utilizes a unique trapezoidal prism column 22 design, which increases the contact area between the column 22 and the base plate 21. This makes the force applied by the column 22 to the base plate 21 more even, effectively improving the problem of the base plate 21's edges easily lifting, and enhancing the stability and service life of the roof rack. Simultaneously, the various components are connected in a detachable manner, facilitating installation, disassembly, and maintenance. The reinforcing rib 11 enhances the load-bearing capacity of the crossbar 1, the lock cover 3 and lock cylinder 31 improve the safety of the roof rack, and the sealing strip 14 reduces the ingress of rainwater or other debris. These designs all improve the overall performance of the roof rack, representing a significant improvement and enhancement compared to existing technologies.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
