Description

Technical Field

[0001] The invention belongs to the technical field of automobile supplies, and in particular relates to a quick-assembly automobile shock-absorbing luggage rack. Background Art

[0002] A car luggage rack specifically refers to a bracket installed on the roof for carrying large items. It is the basis of all roof-mounted solutions. Car luggage racks are most commonly used for self-driving travel. They are used with roof boxes and roof frames to carry travel luggage, thereby increasing the space inside the car. Other sports equipment such as skis, bicycles, and sailboats can also be carried. At present, most car models equipped with car luggage racks are SUVs and off-road vehicles.

[0003] The existing automobile luggage rack includes a shock absorbing device and a binding device. The shock absorbing device is clamped with a longitudinal rail fixed on the automobile. A binding mechanism is installed above the shock absorbing device. The binding mechanism is used to fix the luggage. The shock absorbing device can reduce the bumping of the luggage rack on a bumpy road, so that the luggage and the luggage rack will not be separated due to the bumps.

[0004] Although the existing automobile luggage rack can fix the luggage and achieve shock absorption for the luggage rack, the luggage on the luggage rack will inevitably move during the driving of the car, resulting in uneven force on the luggage rack. When the luggage on the luggage rack is not placed properly, it will also cause uneven force on the luggage rack. The uneven force luggage rack may not only have structural bending or distortion, which will affect the normal use of the luggage rack, but also have a certain impact on the suspension system of the vehicle.

[0005] Therefore, in view of the above situation, it is urgent to develop a quick-assembly automobile shock-absorbing luggage rack to overcome the shortcomings in current practical applications. Summary of the invention

[0006] In view of the deficiencies in the prior art, an object of the embodiments of the present invention is to provide a quick-assembly shock-absorbing luggage rack for a car to solve the problems in the above-mentioned background technology.

A group of connecting rods C drives the connecting rod C in an adjacent group of control units to rotate by driving the slider C to slide in the guide groove. The two groups of connecting rods B and the two groups of connecting rods C in the adjacent control units drive their respective sliders B and sliders C to slide by rotation. The sliders B and sliders C in the adjacent control units drive their respective elastic support units to move downward by sliding and cooperating with the connecting shaft and slider A. The elastic support units at the four corners evenly distribute the pressure on one corner of the luggage frame to the other triangles and move the center of gravity on the luggage frame to its center position by moving downward together.

[0030] like Figures 1 to 3 As shown, as a preferred embodiment of the present invention, the elastic support member 512 preferably adopts an elastic support structure composed of a shock-absorbing spring and a shock-absorbing damper. The shock-absorbing damper can achieve shock absorption for the luggage frame 4 by cooperating with the shock-absorbing spring, thereby reducing the impact force and inertia force on the luggage during driving of the car, thereby better protecting the items in the luggage frame 4 and preventing them from being damaged.

[0031] In this embodiment, when the pressure on the luggage frame 4 is biased toward one corner of the luggage frame 4, the pressure on the corner of the luggage frame 4 drives a group of connecting members A511 matched therewith to move downward, and the group of connecting members A511 drives a group of connecting members B513 to move downward through the elastic support member 512, and the group of connecting members B513 drives a group of connecting shafts 521 matched therewith to move; A group of connecting shafts 521 drives a group of sliders A522 to slide in the guide groove 31, and a group of connecting shafts 521 can drive two groups of connecting rods A523 arranged crosswise thereon to rotate alternately by moving, and the two groups of connecting rods A523 can drive a group of connecting rods B524 and a group of connecting rods C526 connected thereto to rotate by rotating alternately, a group of connecting rods B524 can drive a group of connecting rods B524 in an adjacent group of control units 52 to rotate by driving a slider B525 to slide in the guide groove 31, so that the two adjacent groups of connecting rods B524 can rotate alternately, and a group of connecting rods C526 can drive a group of connecting rods C526 in an adjacent group of control units 52 to rotate by driving a slider C527 to slide in the guide groove 31, so that the two groups of connecting rods C526 rotate alternately; In the adjacent control units 52, the two groups of connecting rods B524 and the two groups of connecting rods C526 drive their respective sliders B525 and sliders C527 to slide by rotating, so that when one or more elastic support units 51 are subjected to downward pressure, that is, when the luggage items are unevenly placed in the luggage frame 4, the sliders B525 and sliders C527 in the affected one or more groups of control units 52 will slide accordingly; Since slider B525, slider C527, connecting shaft 521 and slider A522 cooperate with each other, this sliding will cause the affected elastic support unit 51 to move downward. At the same time, since all the control units 52 are interconnected, this downward movement will also be transmitted to the adjacent elastic support unit 51 through the action of the connecting rod, so that the elastic support units 51 at the four corners of the bottom of the entire luggage frame 4 can move downward together. This not only allows the pressure on one corner of the luggage frame 4 to be evenly distributed to the other triangles, reducing the pressure burden on a single point, thereby preventing damage caused by excessive stress concentration, but also can move the center of gravity on the luggage frame 4 to its center position, which helps to improve the stability of the luggage frame 4, especially during the driving of the car, reduce the tilting or shaking caused by the shift of the center of gravity, protect the internal items from damage, and improve the overall use experience and safety of the car luggage rack.
