It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0025] Refer to Figures 1-7 As shown, a support structure for a car roof rack in a preferred embodiment of the present utility model includes a pair of left and right symmetric extraction and discharge assemblies 1. Both the front and rear ends of the extraction and discharge assembly 1 are fixedly connected with support assemblies 2. The inner ends of the support assemblies 2 are hinged with a plurality of racks 3; the rack 3 includes a plurality of first connecting rods 301 arranged at equal intervals. Both the front and rear ends of the first connecting rod 301 are hinged with second connecting rods 302, and the second connecting rods 302 are hinged with the support assembly 2; the bottom end of the first connecting rod 301 is fixedly connected with an airbag 303, and the airbag 303 is adapted to the extraction and discharge assembly 1 and the support assembly 2;

[0026] The first connecting rod 301 and the second connecting rod 302 are used for the user to place luggage. Among them, the first connecting rod 301 and the second connecting rod 302 cooperate. The luggage is placed on the first connecting rod 301. The first connecting rod 301 bears the weight, and sinks downward through the hinged second connecting rod 302 to keep the center of gravity on the second connecting rod 302, reducing the weight borne by the second connecting rod 302. When stacking a large number of luggage, the luggage can always maintain the center, preventing the center of gravity of the luggage from shifting outward. During high-speed movement, it can prevent the luggage from falling. At the same time, the airbag 303 can support and buffer the first connecting rod 301, preventing the luggage from being too heavy and squeezing the car roof, and buffering the first connecting rod 301 when the vehicle is moving, preventing the luggage from being jolted up due to being too heavy on bumpy roads.

[0027] The support assembly 2 includes a plurality of symmetrically distributed suction cups 205. The top end of the suction cup 205 is fixedly connected with a connection block 204. The top end of the connection block 204 is hinged with a hinge joint 203. The top end of the hinge joint 203 is fixedly connected with a cross bar 201, and the inner end of the cross bar 201 is fixedly connected with the extraction and discharge assembly 1.

[0028] The inner end of the cross bar 201 is provided with a plurality of grooves, and the grooves are hinged to the second connecting rod 302.

[0029] The outer end of the cross bar 201 is provided with a screw 202. The screw 202 penetrates through the cross bar 201, the groove and the second connecting rod 302, and the screw 202 is rotatably connected to the second connecting rod 302;

[0030] Through a plurality of symmetrically distributed suction cups 205, it can be firmly adsorbed on the roof of the vehicle through the cooperation of the connecting block 204 and the hinge joint 203, meeting the installation requirements at different angles, increasing the connection stability between the roof rack and the roof. During the driving of the vehicle, especially when driving at high speed, making sharp turns or encountering bumpy road conditions, it can effectively prevent the roof rack from shaking or falling off, ensuring driving safety.

[0031] The gas extraction assembly 1 includes a connecting shell 101. The connecting shell 101 is fixedly connected to the cross bar 201. An air pump 102 is fixedly connected inside the connecting shell 101. The output end of the air pump 102 is fixedly connected to an air pipe 103. The air pipe 103 penetrates through the connecting shell 101 and is communicated with the suction cup 205.

[0032] A hole is opened at the top end of the connecting shell 101;

[0033] By connecting the air pump 102 to the suction cup 205 through the air pipe 103, the adsorption force of the suction cup 205 can be controlled by the air pump 102, enabling it to be adjusted according to different load requirements and road conditions, improving the flexibility and reliability of the use of the roof rack. When loading heavier luggage or driving on poor road conditions, the adsorption force of the suction cup 205 can be increased to ensure the stability of the roof rack; while when unloading luggage or needing to retract the roof rack, the adsorption force can be reduced for convenient operation.

[0034] Specific implementation process: First, the suction cup 205 is firmly adsorbed on the roof of the vehicle through the cooperation of the connecting block 204 and the hinge joint 203, meeting the installation requirements at different angles. At the same time, the air pump 102 is connected to the suction cup 205 through the air pipe 103. Initially, the suction cup 205 has a basic adsorption force. When the vehicle is loaded with heavier luggage or driving on complex road conditions, the air pump 102 works to suck air into the suction cup 205 to increase the adsorption force and ensure the stability of the roof rack. The user places the luggage on the first connecting rod 301 of the rack 3. As the weight of the luggage increases, the first connecting rod 301 sinks under the weight and through the hinge structure with the second connecting rod 302, keeping the center of gravity of the luggage at the center position to prevent the luggage from falling during high-speed driving. At the same time, the airbag 303 at the bottom end of the first connecting rod 301 supports and buffers the first connecting rod 301, preventing the roof from being squeezed by the heavy luggage and preventing the luggage from being jolted up on bumpy roads.
