Description

Technical Field

[0001] This utility model relates to the field of roof rack technology, specifically an automatically foldable and retractable roof rack. Background Technology

[0002] A roof rack is a support frame or component installed on the roof of a car to securely and conveniently hold luggage. It's commonly found on hatchback station wagons, SUVs, and MPVs. Besides its decorative and aesthetic purpose, a roof rack can hold items that won't fit in the trunk, such as large luggage, bicycles, folding beds, etc. As long as the owner secures the goods properly, especially with the addition of luggage ropes or nets, it can carry more than you might expect.

[0003] Existing roof luggage is usually a one-piece structure that cannot be folded and retracted, resulting in a high roof height. When not in use, this can affect the vehicle's usability and the overall aesthetics of the vehicle. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised in the background art by proposing an automatically foldable and retractable roof rack.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an automatically folding and retractable roof rack, including a base, support rods, connecting rods, baffles, fixing blocks, and limiting components. Multiple support rods are respectively arranged on the left and right sides of the base, and the multiple support rods on each side are equally spaced. Each of the multiple support rods on each side is hinged to the side end of the connecting rod. Baffles are respectively arranged on the front and rear sides of the base. Fixing blocks are fixedly arranged at both ends of the connecting rod, and the fixing blocks are provided with limiting components inside.

[0007] Preferably, one end of the support rod is hinged to the base, and the other end of the support rod is hinged to the connecting rod.

[0008] Preferably, the upper end of the base is provided with limit holes around its perimeter.

[0009] Preferably, a first positioning hole is provided on one side of the baffle, and a second positioning hole is provided on the other side of the baffle.

[0010] Preferably, the limiting component includes a screw, a slider, a locking block, and a spring;

[0011] One side of the outer wall of the screw is threadedly connected to the fixing block, and the other side of the outer wall of the screw is rotatably connected to the slider. The outer wall of the slider is in contact with the fixing block, and the side end of the slider is pressed against the locking block. The side of the locking block adjacent to the slider is slidably connected to the fixing block. The two ends of the spring are fixedly connected to the fixing block and the locking block, respectively.

[0012] Preferably, the radial cross-sectional shape of the end of the locking block away from the spring is the same as that of the first positioning hole and the second positioning hole, the outer diameter of the screw is the same as that of the inner diameter of the limiting hole, and when the connecting rod and the baffle are both perpendicular to the base, the first positioning hole can match the locking block, and the screw can match the limiting hole.

[0013] When the baffle is parallel to the base and the connecting rod is in contact with the base, the second positioning hole can match the locking block.

[0014] This utility model proposes an automatically folding and retractable roof rack, the advantages of which are as follows: By rotating the screw, the locking block is separated from the second positioning hole by the spring force. Then, the baffle is moved to be perpendicular to the base, and the support rod is moved through the connecting rod to be perpendicular to the base. Then, the screw is rotated in the opposite direction to match the locking block with the first positioning hole. At the same time, the screw is matched with the corresponding limiting hole. Similarly, the other three locking blocks are connected to the first positioning hole, thereby realizing the unfolding of the roof rack. By rotating the screw, the locking block is separated from the first positioning hole. Then, the baffle and connecting rod are reset to connect the locking block with the second positioning hole, realizing the folding and retraction of the roof rack. This avoids the large space occupied by the non-foldable roof rack when it is not in use, which affects the driving of the vehicle, and makes the vehicle body more aesthetically pleasing.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-4 An automatically foldable and retractable roof rack includes a base 1, support rods 2, connecting rods 3, baffles 4, fixing blocks 5, and limiting components. Multiple support rods 2 are provided on the left and right sides of the base 1, and the multiple support rods 2 on each side are equally spaced. The multiple support rods 2 on each side are hinged to the side end of the connecting rods 3. Baffles 4 are provided on the front and rear sides of the base 1, and the baffles 4 can be flipped along the base 1. The support rods 2 can be rotated along the base 1. Fixing blocks 5 are fixedly provided at both ends of the connecting rods 3, and the fixing blocks 5 are provided with limiting components inside.

[0022] One end of the support rod 2 is hinged to the base 1, and the other end of the support rod 2 is hinged to the connecting rod 3. The connecting rod 3 can drive multiple support rods 2 to move. Limiting holes 101 are provided around the upper end of the base 1. A first positioning hole 401 is provided on one side of the baffle 4, and a second positioning hole 402 is provided on the other side of the baffle 4.

[0023] The limiting assembly includes a screw 6, a slider 7, a locking block 8, and a spring 9. One side of the outer wall of the screw 6 is threadedly connected to the fixing block 5, and the other side of the outer wall of the screw 6 is rotatably connected to the slider 7. The lower part of the slider 7 adjacent to the locking block 8 is inclined. When the inclined surface of the slider 7 moves to correspond with the locking block 8, the elastic force of the spring 9 drives the locking block 8 to move towards the slider 7, so that the locking block 8 separates from the second positioning hole 402, allowing the baffle 4 to flip. When the inclined surface of the slider 7 moves away from the locking block 8, the slider 7 pushes the locking block 8 to move and connect with the first positioning hole 401. The outer wall of the slider 7 is in contact with the fixing block 5, and the side end of the slider 7 is pressed against the locking block 8. The side of the locking block 8 adjacent to the slider 7 is slidably connected to the fixing block 5. The two ends of the spring 9 are fixedly connected to the fixing block 5 and the locking block 8, respectively.

[0024] The radial cross-sectional shape of the end of the locking block 8 away from the spring 9 is the same as that of the first positioning hole 401 and the second positioning hole 402. The outer diameter of the screw 6 is the same as that of the inner diameter of the limiting hole 101. When the connecting rod 3 and the baffle 4 are both perpendicular to the base 1, the first positioning hole 401 can match the locking block 8, and the screw 6 can match the limiting hole 101. When the baffle 4 is parallel to the base 1 and the connecting rod 3 is in contact with the base 1, the second positioning hole 402 can match the locking block 8.

[0025] Specifically, the base 1 has waist-shaped grooves at both ends to fix it to the roof. When luggage needs to be placed, the operator rotates the screw 6, which moves along the threaded hole of the fixing block 5. At the same time, the screw 6 rotates along the slider 7, and the screw 6 drives the slider 7 to move, so that the inclined surface of the slider 7 corresponds to the locking block 8. This causes the locking block 8 to be separated from the second positioning hole 402 by the elastic force of the spring 9. Then, the baffle 4 is moved to be perpendicular to the base 1, and the support rod 2 is moved through the connecting rod 3 to be perpendicular to the base 1. Then, the screw is rotated in the opposite direction. 6. This allows the locking block 8 to match the first positioning hole 401, and the screw 6 to match the corresponding limiting hole 101. Similarly, the other three locking blocks 8 are connected to the first positioning hole 401, thereby enabling the luggage rack to unfold. By rotating the screw 6, the locking block 8 is separated from the first positioning hole 401. Then, the baffle 4 and connecting rod 3 are reset, thereby connecting the locking block 8 to the second positioning hole 402, enabling the luggage rack to be folded and retracted. This avoids the luggage rack taking up too much space when it is not foldable, which would affect vehicle driving.

[0026] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
