Detailed implementation manners

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the components related to the present invention are shown in the drawings rather than the entire component structure.

[0025] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication of the components within two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above and to the right", and "on the top" of the second feature includes the first feature being directly above and diagonally above the second feature, or simply indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below and to the left", and "underneath" the second feature includes the first feature being directly below and diagonally below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0027] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] To increase the storage capacity of a vehicle, a vehicle roof rack is generally installed on the vehicle roof. The existing vehicle roof racks generally include a base and a storage frame. The storage frame is connected to the vehicle roof through the base. This will make the vehicle roof rack on the roof relatively high, thus causing the overall center of gravity of the vehicle roof rack to move upward. When the vehicle brakes, the items in the storage frame will drive the storage frame to generate a momentum to move forward. Due to the relatively high center of gravity, the stress generated by the connecting parts above and below the base may cause the storage frame to separate from the base on the roof, or the base to separate from the roof, resulting in an accident.

[0029] To solve the above problems, as Figures 1 to 4 shown, the present invention provides a vehicle roof rack, which includes a front fork assembly 1, a rear end assembly 2 and a cross beam 3. There are two groups of front fork assemblies 1. The front fork assemblies 1 are respectively connected to both sides of the rear end assembly 2. The front fork assemblies 1 are connected by the cross beam 3. The cross beam 3, the front fork assemblies 1 and the rear end assembly 2 enclose a storage area. The front fork assembly 1 can be fixed on the upper end surface of the roof.

[0030] The above-mentioned front fork assembly 1 can not only serve as the outer wall of the storage area, but also serve as the upper end surface connected to the roof. Integrating the connecting parts with the side wall of the storage area in this way can save the connecting parts, reduce the height of the vehicle roof rack, and save the production cost. The cross beam 3 serves as the ground of the storage area, and items can be placed on the cross beam 3. The cross beam 3 not only serves as the bottom surface, but also can reinforce the two front fork assemblies 1, improving the stability of the vehicle roof rack.

[0031] As Figures 1 to 4 shown, the front fork assembly 1 includes a first load-bearing beam 11 and a first enclosing beam 12. The front end of the first enclosing beam 12 is connected to the first load-bearing beam 11, and the rear end of the first enclosing beam 12 is parallel to the first load-bearing beam 11;

[0032] The rear end assembly 2 includes a second load-bearing beam 21 and a second enclosing beam 22. The first enclosing beam 12 is connected to the second enclosing beam 22. The second load-bearing beam 21 is connected to the first load-bearing beam 11. The cross beam 3 is connected to the first load-bearing beam 11.

[0033] The first load-bearing beam 11 of the present invention is connected to the vehicle roof, and the first enclosure beam 12 is welded to the first load-bearing beam 11 at the front end. The first load-bearing beam 11 at the rear end is bent upward by a certain height so that the second enclosure beam 22 is parallel to the second load-bearing beam 21. The items to be placed generally need to be larger than the above-mentioned parallel spacing, so that the front fork assembly 1 not only has a connecting function but also has the function of enclosing the side wall of the storage area.

[0034] Similarly, the second load-bearing beam 21 and the second enclosure beam 22 of the rear-end assembly 2 are respectively connected to the corresponding first load-bearing beam 11 and the first enclosure beam 12, so that the rear end of the storage area is also blocked by the second enclosure beam 22 to prevent the items in the storage area from falling.

[0035] As Figures 1 to 4 shown, a clamping joint 41 is formed at the bottom of the base 4 of the present invention. The clamping joint 41 can be connected to a clamping groove formed on the vehicle roof. A first through hole 411 is formed at the bottom of the clamping joint 41, and a first screw 5 passes through the first through hole 411 and is connected to a first screw hole at the bottom of the clamping groove.

[0036] The base 4 of the present invention is inserted into a corresponding groove on the vehicle roof to fix the upper automobile luggage rack. The above-mentioned clamping joint 41 forms a protruding portion downward, and the protruding portion is clamped in the clamping groove on the vehicle roof, which can reduce the shaking amplitude of the automobile luggage rack.

[0037] Optionally, the material of the base 4 of the present invention is resin. Since the resin is lighter in weight and lower in cost, it can reduce the manufacturing cost of the automobile luggage rack. At the same time, the automobile luggage rack also includes a sleeve 6. The sleeve 6 is inserted into the clamping joint 41, and the first screw 5 abuts against the sleeve 6. The material of the sleeve 6 is metal.

[0038] Since the base 4 is finally connected to the vehicle roof by screws, if the screws are in direct contact with the resin base 4, it is easy to cause the base 4 to crack. When the vehicle brakes suddenly, the base 4 will be squeezed by the direct hard screws, which is easy to crush the base 4. Therefore, a metal sleeve 6 is sleeved outside the screws to increase the contact area with the resin material and reduce the pressure of the contact part, preventing the base 4 from cracking when the vehicle decelerates or accelerates.

[0039] As Figures 1 to 4 shown, the cross beam 3 is connected to the front fork assembly 1 through a clamping ring 7. The clamping ring 7 also includes an upper clamping ring 71 and a lower clamping ring 72. The front ends of the upper clamping ring 71 and the lower clamping ring 72 enclose a C-shaped groove, and the front fork assembly 1 is clamped in the C-shaped groove.

[0040] An opening is formed in the C-shaped groove at the front end of the present invention. The opening is used to clamp the cross beam 3 and the front fork assembly 1 to ensure the stability of the connection of the cross beam 3 and make the automobile luggage rack more stable.

[0041] It should be particularly noted that multiple groups of crossbeams 3 of the present invention can be installed. The crossbeams 3 are parallel to each other. The smaller the spacing between them, the smaller the volume of items that can be placed on the car roof rack. At the same time, the crossbeams 3 can be respectively clamped on the first retaining beam 12 and the first load-bearing beam 11 at the lower end. The crossbeams 3 on the first retaining beam 12 at the upper end can prevent the items in the car roof rack from sliding forward.

[0042] As Figures 1 to 4 shown, a first rectangular hole 73 is formed on the snap ring 7 of the present invention, and the connecting screw passes through the first rectangular hole 73 and is connected to the first connection hole on the crossbeam 3.

[0043] Setting the rectangular hole 73 can adjust the spacing between the crossbeam 3 and the front fork part, and can horizontally adjust the length of the car roof rack, so that the car roof rack can adapt to different vehicle models, with stronger versatility. It can also make the storage area of the car roof rack become adjustable, and the crossbeam 3 and the snap ring 7 can move relative to each other along the length direction of the first rectangular hole 73.

[0044] As Figures 1 to 4 shown, the second retaining beam 22 includes a first straight beam and a first bent beam, and the second load-bearing beam 21 includes a second straight beam and a second bent beam. The first straight beam is connected to the first retaining beam 12 through the first bent beam, and the second straight beam is connected to the first load-bearing beam 11 through the second bent beam.

[0045] The rear end assembly 2 of the present invention is provided with corresponding first straight beam and second straight beam, which are arranged at the rear end of the car roof rack to prevent the car luggage from slipping off from the rear end.

[0046] The crossbeam 3 of the car roof rack of the present invention is a rectangular tube. The upper end surface of the rectangular tube can increase the contact area with the luggage in the storage area, while the tube bodies used for the front fork assembly 1 and the rear end assembly 2 are circular, which can save materials, facilitate cutting, and are convenient for installation and connection through the adjustment assembly.

[0047] Optionally, as Figures 1 to 4 shown, the car roof rack of the present invention further includes an adjustment assembly. The first straight beam, the first bent beam and the first retaining beam 12 are sequentially connected through the adjustment assembly, and the second straight beam, the second bent beam and the first load-bearing beam 11 are also sequentially connected through the adjustment assembly;

[0048] The adjustment assembly includes a plug connector and a docking part. A plug hole is formed at the front end of the docking part, a second screw hole is formed on the plug connector, and a second rectangular hole 73 is formed at the upper end of the docking part. The second screw passes through the second rectangular hole 73 and is connected to the second screw hole; the plug connectors and the docking parts are in one-to-one correspondence, and the plug connectors and the docking parts are respectively arranged at both ends of the first straight beam, the first bent beam, the first retaining beam 12, the second straight beam, the second bent beam and the first load-bearing beam 11.

[0049] Through the above-mentioned adjusting components, the first straight beam and the first bent beam inside the rear-end component 2 can be adjusted in the width direction and have the same length as the cross beam 3, making the versatility of the car roof rack stronger and capable of accommodating more items. Similarly, the second straight beam and the second bent beam also move synchronously with the adjusting components on the first straight beam.

[0050] Adjusting components are also used to connect the first bent beam and the second bent beam to the first load-bearing beam 11 and the first enclosing beam 12, enabling the length direction of the car roof rack to be adjusted and applicable to different vehicle models.

[0051] The plug connector formed at the end of the above-mentioned beam body is connected to the docking part, and the relative position of the second screw and the docking part is changed through the second rectangular hole 73, realizing the change in the relative position along the length direction of the second rectangular hole 73, and finally making the connection.

[0052] Optionally, the car roof rack of the present invention further includes a housing, an accommodation cavity is formed inside the housing, and the adjusting components are arranged in the accommodation cavity.

[0053] In order to prevent dust from entering and keep the appearance of the car roof rack clean, the adjusting components at the connection are covered, which can block dust from entering and effectively prevent corrosion by external water vapor.

[0054] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
