Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a clamping mechanism for external connection of a vehicle roof rack and a vehicle. Background Technology

[0002] As cars gradually become an indispensable means of transportation in people's daily lives, the accessories installed on cars (such as roof racks, bicycle racks, ski equipment holders, etc.) play an important role in meeting users' travel and outdoor activity needs. Especially when it is necessary to carry large items or special equipment, the application of roof racks is particularly necessary.

[0003] Existing vehicle roof racks or similar clamping structures are typically installed in the following two ways:

[0004] Drilling holes in the roof or side beams and bolting them in place has obvious drawbacks: it damages the vehicle's integrity by disrupting the original roof structure, potentially negatively impacting the strength of the roof longitudinal beams; and it reduces the vehicle's waterproofing capabilities by allowing moisture to seep into the roof through the holes, especially in rainy or humid environments, potentially damaging electronic components or the roof material.

[0005] Some roof racks are attached to the vehicle surface using suction cups, adhesive strips, or other methods. While this solves the drilling problem, it has low reliability: poor stability: the attachment is prone to detachment in high or low temperatures or humid climates. Limited applicability: it cannot meet the load requirements of high-speed driving or withstand the pressure of large items over a long period. Summary of the Invention

[0061] Example 1

[0062] like Figure 1 As shown, this embodiment provides a clamping mechanism for external connection of a vehicle roof rack, including: a first clamping component 2, a second clamping component 1, a fastener 3, and an external connector 4; the first clamping component 2 and the second clamping component 1 are respectively clamped on the outer periphery of the roof longitudinal beam 5, and are respectively located on both sides of the longitudinal beam in the width direction; the fastener 3 is connected to the first clamping component 2 and the second clamping component 1 to limit the relative position of the first clamping component 2 and the second clamping component 1; the external connector 4 for installing external devices is connected to the first clamping component 2 or the second clamping component 1.

[0063] like Figure 2The diagram shows a three-dimensional representation of a clamping mechanism cooperating with a roof longitudinal beam. An external connector 4 is mounted on the structure combining the first clamping component 2 and the first clamping component 1. The first clamping component 2 and the second clamping component are mounted on the roof longitudinal beam 5 via fasteners 3. It is understood that this application employs a non-destructive installation method, clamping the components to the outer periphery of the roof longitudinal beam 5 without any drilling or mechanical intrusion, thus avoiding damage to the original vehicle structure; protecting the vehicle's waterproof performance: the seal remains unaffected, eliminating the risk of water leakage due to drilling, making it particularly reliable in rainy or humid environments; extending vehicle lifespan: the absence of drilling means no subsequent corrosion or structural fatigue problems due to holes, contributing to a longer service life for the vehicle. This application utilizes a first clamping component 2 and a second clamping component 1 to securely fasten to the outer periphery of the vehicle's longitudinal beam. Both sides are tightly attached to the surface of the roof longitudinal beam 5 and firmly connected via fasteners 3, providing high stability: It dynamically adapts to high-load environments, safely supporting heavy items (such as roof boxes, bicycle racks, etc.) without slippage or loosening, maintaining its firmness even under high-speed and bumpy driving conditions. It is resistant to environmental changes: regardless of high temperature, low temperature, or humid conditions, this clamping method maintains a strong clamping effect and is not prone to deformation or adhesive failure due to temperature differences; it has strong vibration resistance and anti-detachment properties: whether on winding mountain roads, bumpy road conditions, or during sudden braking, it can firmly hold the external device to prevent it from detaching from the vehicle's longitudinal beam.

[0064] like Figure 4 As shown in the specific example provided in this embodiment, the first clamping assembly 2 includes a first mounting member 21 and a first clamping member 22; the side of the first mounting member 21 facing the roof longitudinal beam 5 is a first contact side that fits the roof longitudinal beam 5, and its bottom surface facing the roof surface is a first contact bottom surface that fits the roof surface; the first clamping member 22 is mounted on the side of the first mounting member 21 away from the roof longitudinal beam 5; the second clamping member 12 includes a second mounting member 11 and a second clamping member 12; the side of the second mounting member 11 facing the roof longitudinal beam 5 is a second contact side that fits the roof longitudinal beam 5, and its bottom surface facing the roof surface is a second contact bottom surface that fits the roof surface; the second clamping member 12 is mounted on the side of the second mounting member 11 away from the roof longitudinal beam 5; the fastener 3 passes through the first clamping member 22 and is connected to the second fastener 3. It should be noted that in this embodiment, the first mounting member 21 and the second mounting member 11 are made of elastic materials (such as silicone or rubber materials) to ensure that the first mounting member 21 and the second mounting member 11 fit tightly with the roof longitudinal beam 5 and the roof surface, and can be adapted to different vehicle models.

[0065] Understandably, the first mounting component 21 and the second mounting component 11, being made of elastic material, can slightly deform according to the geometry of the roof longitudinal beam 5 (such as arc-shaped, trapezoidal, rectangular, etc. cross-sections), thereby better conforming to the sides and bottom of the roof longitudinal beam 5. Through the inherent flexibility and "self-adaptive" capability of the material itself, the contact area of ​​the clamping components increases, resulting in a tighter fit and reducing the likelihood of loosening due to external forces or vibrations. The fastener 3 applies clamping force to the roof longitudinal beam 5 through the first clamping component 22 and the second clamping component 12. During the force application, the elastic mounting component undergoes moderate compression and reacts against the roof longitudinal beam 5. Under the reaction force, the elastic material enhances the stable clamping of the roof longitudinal beam 5, dispersing point-like forces into surface-like forces, effectively protecting the longitudinal beam from localized indentations or damage.

[0066] When a vehicle is traveling at high speed or on bumpy roads, the roof longitudinal beam 5 and the clamping assembly will be subjected to dynamic vibration and impact forces. The elastic mounting component can absorb and buffer some of the external impacts through its own deformation, thereby reducing the transmission of these dynamic loads to the entire clamping structure and improving the stability of the system. Even under poor road conditions or heavy loads, the luggage rack can still maintain a firm connection with the vehicle, reducing the long-term effect of fatigue stress on the fasteners 3 and the clamping assembly, and extending their service life.

[0067] The elastic material possesses excellent deformation capabilities, allowing it to adjust its contour to closely conform to longitudinal beams of various cross-sectional shapes, such as rectangular, arc-shaped, triangular, or trapezoidal sections. This clamping mechanism can adapt to different vehicle designs without the need for specific molds, improving universal compatibility and eliminating assembly instability issues caused by differences in longitudinal beam structures. The sides and bottom surfaces of the elastic mounting component near the roof longitudinal beam 5 form the contact area. Through its flexibility, it provides isolation and protection, preventing direct friction or pressure from hard materials that could damage the paint layer or metal parts of the roof surface during repairs.

[0068] like Figure 4 and Figure 6 and Figure 7 As shown in the specific example provided in this embodiment, the first mounting member 21 has at least two first positioning posts 211 on its side away from the roof longitudinal beam 5; the first clamping member 22 has a first positioning hole 221 corresponding to each first positioning post 211; when the first clamping member 22 is installed on the first mounting member 21, the first positioning post 211 is located in its corresponding first positioning hole 221. Specifically, in this embodiment, the first mounting member 21 has five first positioning posts 211, and the first clamping member 22 has five corresponding first positioning holes 221, but this application does not limit the specific number of first positioning posts 211.

[0069] Understandably, each positioning post on the first mounting component 21, combined with the corresponding positioning hole on the first clamping component 22, provides a clear and fixed installation reference. This ensures that the first clamping component 22 will not shift position when installed on the first mounting component 21, guaranteeing precise alignment of the clamping structure. Even during multiple disassembly and assembly processes, it can still quickly return to its initial precise installation position. The positioning posts and positioning holes form a natural "locking" mechanism, reducing common installation problems such as misalignment, tilting, or reverse installation during user operation, improving assembly efficiency, and reducing the complexity of user operation.

[0070] like Figures 4 to 6 As shown in the specific example provided in this embodiment, the second mounting member 11 has at least two second positioning posts 111 on its side away from the roof longitudinal beam 5; the second clamping member 12 has a second positioning hole 121 corresponding to each second positioning post 111; when the second clamping member 12 is installed on the second mounting member 11, the second positioning post 111 is located in its corresponding second positioning hole 121. Specifically, the cooperation between the second mounting member 11 and the second clamping member 12 in this embodiment is the same as the cooperation principle of the first mounting member 21 and the first clamping member 22 described above, and has the same effect, which will not be elaborated here.

[0071] like Figures 4 to 8 As shown, in a specific example provided in this embodiment, the first clamping member 21 is provided with at least two through first connecting holes 222 along its width direction; the second clamping member 12 is provided with a first screw hole 122 corresponding to each of the first connecting holes 222; the fastener 3 includes a fastening bolt 31, which passes through the first connecting hole 222 and is connected to the first screw hole 122.

[0072] It is understandable that the through connection of the fastening bolts 31 achieves a firm connection between the first clamping member 22 and the second clamping member 12, and provides uniform force support. This embodiment uses a design with multiple first connecting holes 222 and first screw holes 122, which can effectively distribute the mechanical load when installing the upper and lower surfaces of the longitudinal beam, and avoid excessive force at a single point, which could lead to the clamp loosening or deformation.

[0073] like Figures 5 to 8 As shown, in a specific example provided in this embodiment, the first clamping member 22 has at least one arc-shaped block 223 on one side facing the second clamping member 12; the second clamping member 12 has an arc-shaped groove 126 corresponding to each arc-shaped block 223.

[0074] Understandably, the cooperation between the arc groove 126 and the arc block 223 can reduce the possibility of component misalignment or detachment caused by vibration, lateral shear stress or external impact; improve the overall structure's impact resistance under dynamic loads, such as the stability of large items when vehicles are driving on bumpy roads or at high speeds; and enhance the long-term reliability of the equipment.

[0075] like Figure 1 , Figure 4 and Figure 9 As shown in the specific example provided in this embodiment, the first clamping component 2 or the second clamping component 1 is provided with at least two connecting screw holes 123; the external component 4 is provided with mounting holes 42 corresponding to each connecting screw hole 123, and the fixing bolt 41 passes through the mounting holes 42 and connects to the connecting screw holes 123 to fix the external component 4 to the first clamping component 2 or the second clamping component 1. Specifically, in this embodiment, the second clamping component 12 is provided with four connecting screw holes 123, and the external component 4 is fixed to the second clamping component 12 by fixing bolts 41.

[0076] like Figure 2 As shown, in a specific example provided in this embodiment, the top of the first clamping component 2 or / and the second clamping component 1 is provided with at least one limiting block 125; the external component 4 is provided with a limiting hole 43 corresponding to the limiting block 125.

[0077] Understandably, the limiting block 125 forms a physical limit by inserting into the limiting hole 43 on the external component 4, enabling precise positioning during the initial installation phase before the fastening bolt 31 is tightened. This limiting mechanism provides convenient alignment and locking of the device, while also enhancing the reliability of the connection after assembly. It reduces the difficulty of alignment steps during assembly, accelerating the installation process; prevents horizontal slippage and tilting of the external device during use, improving the safety of the fixed accessories; and complements the fastening design, providing a dual protection mechanism for high-load applications.

[0078] like Figure 3 and Figure 4 and Figure 10 As shown, in a specific example provided in this embodiment, a protective cover 6 is also included; the protective cover 6 has a receiving cavity for accommodating the first clamping component 2 and the second clamping component 1, and a connecting buckle 61 is provided at the top of the receiving cavity; the first clamping component 2 and / or the second clamping component 1 are provided with a connecting slot 124 that cooperates with the connecting buckle 61. Specifically, in this embodiment, the cooperation between the connecting buckle 61 and the connecting slot 124 is a conventional buckle-slot cooperation structure, which will not be described in detail here.

[0079] Understandably, the protective cover 6 surrounds the first clamping component 2 and the second clamping component 1, further protecting the entire structure from external environmental interference after the overall installation is complete. The design of the connecting buckle 61 and the connecting slot 124 ensures that the protective cover 6 can be securely locked onto the clamp, preventing it from easily falling off. It can effectively prevent rainwater, dust, mud, etc. from entering the clamp, delaying the problem of equipment failure due to exposure to corrosion or pollution; improve the visual effect, making the entire roof accessory system more beautiful and integrated; and improve the long-term environmental adaptability of the overall system, ensuring normal use in rain, snow, or harsh outdoor environments.

[0082] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
