Description

Aluminum profiles for car roof racks Technical Field

[0001] This utility model relates to the technical field of aluminum materials, and in particular to the technical field of aluminum profiles for automobile roof racks. Background Technology

[0002] Car roof racks can carry large items that cannot fit in the trunk, such as large luggage, bicycles, folding beds, skis, sailboats, etc., making it convenient for road trips or transporting large items.

[0003] The patent document with publication number CN118182334A shows that the crossbeam is installed in the slot of the aluminum profile of the car roof rack. This installation structure can adjust the position of the crossbeam, but this installation method does not provide high support strength for the end of the crossbeam. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing an aluminum profile for car roof racks that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes an aluminum profile for a car roof rack, comprising a frame body, with first frame strips on the left and right sides of the frame body and second frame strips on the top and bottom sides of the frame body. The first and second frame strips are connected by connectors. Several parallel support beams are provided between the two first frame strips. The support beams are slidably mounted on the first frame strips. A sliding groove is provided on the outer side of the first frame strip. A top edge is provided above the sliding groove, and an upper limit part is provided on the top edge. A bottom edge is provided below the sliding groove, and a lower limit part is provided on the bottom edge. The lower limit part is a buffer cavity formed by continuous bending at the end of the bottom edge. A support crossbar is provided at the top of the buffer cavity. A support upright is provided on the inner side of the buffer cavity. A bending plate is provided on the outer side of the buffer cavity, and a V-shaped groove is provided on the outer side of the bending plate.

[0006] Preferably, a fixing strip is fixedly installed between the two second frame strips, and the fixing strip is provided with fixing holes. The support beam is connected to the fixing holes by fasteners.

[0007] Preferably, the upper limit position is an L-shaped plate.

[0008] Preferably, the opening between the upper limit part and the lower limit part is smaller than the opening of the slide groove, the end of the support beam is provided with a limiting slider, the limiting slider is installed in the slide groove, and the bottom of the support beam abuts against the support crossbar.

[0009] Preferably, the bottom of the first frame strip is provided with a mounting groove.

[0010] Preferably, the support bar is inclined downwards to the outer side.

[0011] The beneficial effects of this utility model are as follows: By setting a lower limit part at the bottom of the slide groove and supporting the support beam with a bending plate, the bending plate will deform under force when heavy objects are placed on the support beam, thus buffering the pressure and improving the support strength of the frame strip for the support beam, and avoiding damage to the luggage rack caused by the pressure when heavy objects are placed on it.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0017] Referring to Figures 1, 2, and 3, an aluminum profile for a car roof rack includes a frame body. First frame strips 1 are provided on the left and right sides of the frame body, and second frame strips 2 are provided on the upper and lower sides of the frame body. The first frame strips 1 and second frame strips 2 are connected by connectors 3. Several parallel support beams 4 are provided between the two first frame strips 1. The support beams 4 are slidably mounted on the first frame strips 1. A sliding groove 5 is provided on the outer side of the first frame strip 1. A top edge 51 is provided above the sliding groove 5, and an upper limit part 6 is provided on the top edge 51. A bottom edge 52 is provided below the sliding groove 5, and a lower limit part 7 is provided on the bottom edge 52. The lower limit part 7 is a buffer cavity 72 formed by continuous bending at the end of the bottom edge 52. A support crossbar 73 is provided at the top of the buffer cavity 72. A support upright plate 74 is provided on the inner side of the buffer cavity 72. A bending plate 75 is provided on the outer side of the buffer cavity 72, and a V-groove 71 is provided on the outer side of the bending plate 75.

[0018] A fixing strip 8 is fixedly installed between the two second frame strips 2. The fixing strip 8 is provided with fixing holes, and the support beam 4 is connected to the fixing holes by fasteners.

[0019] The position and number of support beams can be adjusted as needed. The support beams are equipped with through holes. After installation, they can be fixed by connecting the fixing holes to the through holes with bolts.

[0020] The upper limit section 6 is an L-shaped plate.

[0021] The opening between the upper limit part 6 and the lower limit part 7 is smaller than the opening of the slide groove 5. The end of the support beam 4 is provided with a limiting slider, which is installed in the slide groove 5. The bottom of the support beam 4 abuts against the support crossbar 73.

[0022] The bottom of the first frame strip 1 is provided with a mounting groove 9.

[0023] The support bar 73 is inclined downwards on the outer side.

[0024] When the support beam is subjected to heavy pressure, it will drive the support crossbar to move downward, making the included angle of the V-groove smaller, thus buffering the pressure and preventing damage to the luggage rack.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
