Description

Technical Field

[0001] This invention belongs to the field of luggage rack technology, specifically a streamlined noise-reducing luggage rack for automobile roofs. Background Technology

[0002] Car roof racks are typically installed on the roof of a vehicle to support suitcases, bicycle racks, ski racks, and other external cargo components. Existing roof racks mostly consist of crossbars, longitudinal rails, or supports, and are fixed to the roof sheet metal, roof rails, or pre-embedded mounting positions using bolts, clips, or interlocking structures. For passenger vehicles with curved roofs and streamlined shapes, roof accessories, in addition to load-bearing requirements, must also consider aesthetic harmony, wind resistance control, and wind noise suppression. Therefore, the shape, installation location, and connection structure of the roof rack directly affect the overall user experience of the vehicle.

[0003] In existing technologies, one type of roof rack uses an exposed threaded fastening structure for installation. This type of structure has high connection reliability, but the installation process usually requires special tools, involves multiple steps, and is inconvenient. Furthermore, the exposed fasteners are located on the outside of the roof, making the disassembly path quite obvious and susceptible to external tampering. Another type of roof rack uses external clips or press-fit locking methods. While this can shorten installation time, the locking structure is often located on the outside of the vehicle or at the bottom edge, still presenting the problem of easily accessible trigger points for disassembly. In addition, some roof racks rely solely on unidirectional insertion or elastic engagement during installation, resulting in poor assembly guidance and issues such as misalignment, incomplete locking, or insufficient synchronization between the left and right ends.

[0004] Furthermore, existing roof racks often suffer from insufficient coordination between their streamlined design and locking mechanism layout. If the locking mechanism is large or exposed, it can disrupt the transition between the roof rack and the roof, increasing local airflow separation and causing additional wind noise. If the locking mechanism is deeply concealed, it can lead to complex assembly and disassembly, affecting daily usability. Especially in scenarios requiring quick assembly, reliable locking, and anti-theft features, existing structures often struggle to simultaneously meet the requirements of ease of installation, concealed disassembly, and overall streamlined design.

[0005] Therefore, it is necessary to propose a streamlined noise-reducing roof rack for automobiles. By constructing a connecting and locking structure with guiding cooperation, rotation linkage and internal unlocking features between the main body of the roof rack and the roof platform, the main body of the roof rack can be automatically guided and locked during the pressing process, and the unlocking operation is located inside the vehicle. This improves the problems of inconvenient installation and disassembly, high risk of external disassembly and the impact of structural layout on the streamlined shape of the roof in the existing technology.

[0024] Example 1

[0025] Reference Figures 1-8This embodiment provides a streamlined noise-reducing roof rack for automobiles, including a roof rack body 100, which includes a crossbar 101 and curved plates 102 disposed at both ends of the crossbar 101. A mounting sleeve 103 is disposed below the crossbar 101, and a guide line 104 is disposed on the inner wall of the mounting sleeve 103. A roof platform 200 is provided on the roof platform 200, and a mounting seat 201 is disposed on the mounting seat 201. A connector 300 is fixed in the mounting seat 201, and a connecting post 301 is disposed on the connecting post 301. A guide groove 302 is disposed on the connecting post 301, and the mounting sleeve 103 is sleeved on the connecting post 301. The guide groove 302 is embedded in the guide line 104.

[0026] A base plate 303 is provided at the bottom of the connecting column 301. The base plate 303 is set on the mounting base 201. A connecting shaft 304 is provided below the base plate 303. A first follower wheel 305 is provided at the bottom of the connecting shaft 304.

[0027] The mounting base 201 has an internal intermediate groove 202, and the top of the mounting base 201 has a through groove 203 that communicates with the intermediate groove 202. The first follower wheel 305 is located in the intermediate groove 202, and the connecting shaft 304 is located in the through groove 203.

[0028] The middle groove 202 is also provided with circular grooves 204 on both sides, the circular grooves 204 are connected to the middle groove 202, and a through groove 205 is provided below the circular grooves 204.

[0029] It also includes a limiting member 400, which includes a second follower wheel 401. The second follower wheel 401 is disposed in the circular groove 204 and meshes with the first follower wheel 305. A through shaft 402 is provided at the bottom of the second follower wheel 401.

[0030] A limiting plate 403 is also provided on the through shaft 402, and a first support plate 404 is provided below the limiting plate 403.

[0031] It should be noted that the first support plate 404 is an annular plate, and the central angle it occupies is less than 180 degrees.

[0032] A limiting groove 206 is provided on the inner wall of the through groove 205, a limiting plate 403 is provided in the limiting groove 206, and a second support plate 207 is provided at the bottom of the limiting groove 206.

[0033] Specifically, the central angle occupied by the second support plate 207 and the first support plate 404 is 360 degrees. In the initial state, the first support plate 404 is set on the second support plate 207. Under the action of the spring 405, the first support plate 404 abuts against the second support plate 207. When the first support plate 404 rotates to be completely displaced from the second support plate 207, the first support plate 404 will be pulled down under the action of the spring 405, and the first support plate 404 and the second support plate 207 will engage with each other.

[0034] A spring 405 is provided at the bottom of the limiting plate 403, and a ring 406 is provided at the bottom of the spring 405. The ring 406 abuts against the bottom of the limiting groove 206 under the action of the spring 405.

[0035] The roof platform 200 is internally connected to a rotating rod 208. The two ends of the rotating rod 208 are provided with centrally symmetrical buckles 209. The central axis of the rotating rod 208 coincides with the axis of the through groove 203.

[0036] A positioning ring 402a is provided at the bottom of the through shaft 402.

[0037] Specifically, in the initial state, the second follower wheel 401 is at the top, the spring 405 is in a stretched state, and the first support plate 404 abuts against the second support plate 207. The process of installing the luggage rack body 100 onto the connector 300 is as follows: the mounting bushing 103 is fitted onto the connecting post 301. It should be noted that the position of the connecting post 301 is fixed in the disposed state. Therefore, in the initial state, the end position of the guide groove 302 corresponds to the end position of the guide line 104. Therefore, when the connecting post 301 is inserted into the mounting bushing 103, the guide line 104 is also embedded in the guide groove 302. Since the main body 100 of the luggage rack cannot be rotated by hand, the connecting column 301 is driven to rotate by the guide line 104 during the pressing of the main body 100 of the luggage rack. After rotation, the first follower wheel 305 drives the second follower wheel 401 to rotate. After the main body 100 of the luggage rack is pressed to the bottom, the first support plate 404 rotates until it is completely misaligned with the second support plate 207. The first support plate 404 moves down and is blocked by the second support plate 207. During this process, the first follower wheel 305 is always engaged with the second follower wheel 401. After the first support plate 404 is blocked, the connecting piece 300 is restricted from rotating, so the main body 100 of the luggage rack is locked.

[0038] When disassembly is required, push the bottom of the through shaft 402 upward from inside the vehicle until it reaches the bottom. Then rotate the rotating rod 208 so that the buckle 209 is embedded in the positioning ring 402a. At this time, the first support plate 404 is pushed above the second support plate 207 and fixed in place. Then, lift the luggage rack body 100 upward from outside the vehicle. During the process of lifting the luggage rack body 100, the mounting bushing 103 moves upward, causing the connecting column 301 to rotate and reset to the initial state.

[0039] Therefore, the present invention facilitates the installation and removal of the luggage rack body, and the removal switch is located inside the vehicle to serve as an anti-theft measure.

[0040] It should be noted that the aesthetics of the interior layout are not considered in this application.

[0041] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
