[0002] As an important accessory for automobiles, car roof racks are mainly used to carry suitcases, backpacks, bicycles, and other items, expanding the car's storage space and meeting the needs of users in scenarios such as long-distance travel and outdoor activities. However, existing car roof racks have the following shortcomings in use:

[0003] 1. Poor shock absorption: The car will vibrate during driving, especially when driving on bumpy roads. The vibration will be directly transmitted to the items on the roof rack, which can easily cause the items to collide and be damaged, or even cause the items to slip off the roof rack due to vibration.

[0004] Second, low compatibility: Most roof racks have a fixed mounting structure, which is only applicable to specific car models and cannot be adjusted according to the roof size of different car models, thus having a narrow range of applications.

[0005] Therefore, we proposed a car roof rack with shock absorption and protection functions to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution: a car roof rack with shock absorption and protection function, including a longitudinal bar 1, a cross bar 2 connected to the inner wall of the longitudinal bar 1, and a shock-absorbing pad 3 bonded to the cross bar 2;

[0026] Furthermore, the longitudinal rod 1 has an "I" shaped structure, and the inner wall of the longitudinal rod 1 is equally spaced with horizontal rods 2, which facilitates the assembly of the rotating rod 4. The rotation of the rotating rod 4 synchronously drives the two sets of lead screws 7 to rotate.

[0027] A rotating rod 4 is installed inside the longitudinal rod 1. A first bevel tooth 5 is keyed to the outer wall of the rotating rod 4. A second bevel tooth 6 meshes with the outer side of the first bevel tooth 5. A lead screw 7 is keyed to the inner side of the second bevel tooth 6. A moving plate 8 is threaded to the end of the lead screw 7. A retainer 9 is installed at the end of the moving plate 8. A retainer rod 10 is connected to the inner wall of the retainer 9.

[0028] Furthermore, the movable plate 8 and the longitudinal rod 1 form a sliding structure. The movable plate 8 is distributed at the four corners of the longitudinal rod 1. The movable plate 8 can be driven to move synchronously to adjust the position of the card seat 9. By using the synchronous engagement of the card seat 9 with the roof frame, the convenient assembly of the car roof rack can be achieved.

[0029] Furthermore, the card holder 9 has a "C" shaped structure, and the edges of the card holder 9 are distributed in an inclined manner, which makes it easy for the card holder 9 to be smoothly attached to the roof frame;

[0030] A fixing plate 11 is provided on the crossbar 2. A damping shaft 12 is connected to the inner wall of the fixing plate 11. An adjusting plate 13 is installed on the outer side of the damping shaft 12. A buffer pad 14 is attached to the outer wall of both the adjusting plate 13 and the fixing plate 11.

[0031] Furthermore, the shock-absorbing pad 3 is made of nitrile rubber, and there is a gap between the shock-absorbing pad 3 and the middle section of the fixing plate 11. The shock-absorbing pad 3 is used to provide shock absorption and protection for the luggage, and to prevent the shock-absorbing pad 3 from obstructing the movement of the fixing plate 11.

[0032] Furthermore, the fixing plate 11 and the crossbar 2 at the outermost position form a sliding structure. The fixing plate 11 has an "n" shaped structure. The position of the fixing plate 11 can be adjusted to fit the size of the suitcase and limit and fix it.

[0033] Specifically, when using this car roof rack with shock absorption and protection function, firstly, the crossbar 2 and the longitudinal bar 1 are welded together to form the roof rack body. Shock-absorbing pads 3 are laid on the crossbar 2 and fixed with glue. During installation, the roof rack is placed on the roof, with the slot of the bracket 9 aligned with the roof frame and the clamping rod 10 inside the bracket 9 aligned with the pre-set hole in the roof frame. Rotating the rotating rod 4 causes the first bevel tooth 5 connected by the outer key to rotate. The first bevel tooth 5 drives the meshing second bevel tooth 6 to rotate. The second bevel tooth 6 drives the screw rod 7 connected by the inner key to rotate. The screw rod 7 controls the movement of the moving plate 8 connected by the outer thread. Due to the limit of the longitudinal bar 1, the moving plate 8 is kept moving horizontally. Adjusting the extension length of the moving plate 8 allows the bracket 9 to gradually clamp onto the roof frame, and the clamping rod 10 passes through the pre-set hole in the roof frame to fix the roof rack.

[0034] When loading items, place the items on the shock-absorbing pad 3, slide the fixed plate 11 to the appropriate position according to the size of the items, the fixed plate 11 can slide on the crossbar 2, and drive the adjusting plate 13, so that the adjusting plate 13 rotates on the fixed plate 11 through the damping shaft 12, rotate the adjusting plate 13 to the vertical position, and continue to control the movement of the fixed plate 11, so that the buffer pad 14 on the fixed plate 11 and the adjusting plate 13 fits tightly with the items, and use bolts to lock the fixed plate 11 to the crossbar 2. The fixed plate 11 and the adjusting plate 13 limit the items, thereby achieving shock absorption and protection of the items;

[0035] When unloading items, the fixing plate 11 can be unlocked, and the fixing plate 11 can be moved in the reverse direction to release the fixing plate 11 from fixing the items. The control adjustment plate 13 can be rotated and folded into the inner wall of the fixing plate 11 to avoid occupying space. The control lever 4 can be reversed, and the transmission of the meshing first bevel tooth 5 and second bevel tooth 6 can make the lead screw 7 rotate in the reverse direction. The control moving plate 8 can be gradually moved into the longitudinal rod 1, and the card seat 9 can be gradually moved away from the roof frame to release the fixing of the car roof rack, which is convenient for disassembling the car roof rack. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
