Description

Technical Field

[0001] The present invention belongs to the technical field of roof racks, and particularly relates to a roof rack for a car used for traveling. Background Art

[0002] A station wagon is a derivative car model derived under the trend of humans' advocating nature and being keen on tourism. Compared with SUVs and MPVs, station wagons have lower prices and usage costs, and have a more flexible body, which is convenient for driving and parking. With the improvement of the material living standards of domestic consumers, it has also become a new fashion for urban car owners to drive a station wagon with their families and go on a long journey during holidays. Station wagons can not only travel long distances, but also have enough space to carry sufficient travel equipment.

[0003] An automotive roof rack is a support frame or component installed on the top of the vehicle body to safely and conveniently fix luggage. It is generally used for hatchback station wagons, SUVs, MPVs and other vehicle models. In addition to serving as a decoration and enhancing the aesthetics, a roof rack can hold items that cannot fit in the luggage compartment, such as large luggage, bicycles, folding beds, etc. As long as the owner secures the goods properly, especially by adding a luggage rope net to the goods, it can carry more things than expected.

[0004] Most roof racks on the market do not come with a built-in staircase or a simple manual staircase. Such roof racks are difficult to climb, and it is easy to cause injury to vehicle occupants when retracting or deploying the simple staircase, which affects the access to items, thus reducing the scope of application of the roof rack. Therefore, it cannot meet the actual usage requirements. Summary of the Invention

Positioning bolts 25 are uniformly arranged on the outer side of the inside of the second locking part 23, and the positioning bolts 25 pass through the second locking part 23 and are connected with the first locking part 22. Specifically, by providing the connecting protrusion 24, the first locking part 22 and the second locking part 23 can be engaged, which can prevent the two from shaking or shifting. And the provided positioning bolts 25 pass through the second locking part 23 and are connected with the first locking part 22.

[0040] Among them, as Figure 2 and Figure 9As shown, the automatic opening mechanism includes a support body 26, a connecting rotating shaft 27, a servo motor 28, a push rod body 29, and a tripod 30. The support body 26 is arranged on one side of the interior of the storage box body 20 away from the storage box side plate 32. The connecting rotating shaft 27 is arranged on one side of the support body 26. One end of the servo motor 28 is connected to the connecting rotating shaft 27, and the servo motor 28 can rotate at multiple angles. The push rod body 29 is fixed to the output end of the servo motor 28. The tripod 30 is rotatably connected to the tail end of the push rod body 29.

The connecting rotating shaft 27 arranged on one side of the support body 26 can rotate the servo motor 28 at multiple angles, which is convenient for subsequent driving.

[0041] Among them, as Figure 9 shown, a retractable chute 31 is provided inside the tripod 30, and the inner wall slider of the storage box side plate 32 can slide along the inside of the retractable chute 31. Specifically, by providing the retractable chute 31, the position of the storage box side plate 32 can be limited. The slider inside the storage box side plate 32 can slide along the inside of the retractable chute 31, and then the angle of the storage box side plate 32 can be adjusted, and the storage box side plate 32 can be automatically opened and closed.

[0042] Among them, as Figure 3 and Figure 8 shown, a retractable ladder component 33 is arranged on one side of the interior of the storage box body 20 close to the storage box side plate 32. Specifically, by providing the retractable ladder component 33, it is convenient for the staff to climb, and the items can be quickly taken and placed. The retractable ladder component 33 can be retracted into the storage box body 20, which can avoid wasting space and improve the practicality of the luggage rack body 4.

[0043] Working principle: First, place the luggage rack body 4 at the designated position. Then, slide and connect the connecting rods 7 at both ends of the longitudinal reinforcing rod 8 inside the positioning chute 6, and then pass bolts through the connecting rods 7 to connect with the luggage rack body 4, which can prevent the luggage rack body 4 from shifting. Next, connect the connecting rods 11 at both ends of the transverse reinforcing rod 10 to the positioning chute 6, and the limiting card slots 9 at the upper end of the longitudinal reinforcing rod 8 can be connected with the transverse reinforcing rod 10, which can prevent the transverse reinforcing rod 10 from shifting. Then, snap the protective frame 14 onto the upper end of the stepped groove body 13, and the provided stepped groove body 13 can limit the protective frame 14. The protective frame 14 and the protective net 15 cooperate to filter items, which can prevent goods from falling and affecting the normal driving of the subsequent vehicle, etc. Then, place the storage box body 20 inside the storage port 19, snap the locking part 22 at the lower end of the storage box body 20 inside the locking groove 21, and snap the locking part 23 onto the lower end of the longitudinal reinforcing rod 8 to connect the locking part 22 and the locking part 23. The provided connecting protrusion 24 can ensure the tightness of their fixation. Then, pass the positioning bolt 25 through the locking part 23 to connect with the locking part 22. Subsequently, place the luggage rack body 4 on the upper end of the vehicle body 1. The positioning slider 3 provided at the upper end of the load-bearing rod 2 can limit the luggage rack body 4, which can prevent the luggage rack body 4 from shifting. Then, lock the luggage rack body 4 with the positioning screw 5, which can further improve the stability of the luggage rack body 4. The provided locking groove body 12 can be snapped onto the positioning slider 3, which can prevent the transverse reinforcing rod 10 from shaking.

[0044] Then, through the working switch, command the servo motor 28 to start. The provided servo motor 28 can drive the tripod 30 through the servo motor 28 and the push rod body 29, which can facilitate the subsequent adjustment of the position of the storage box side plate 32. The connecting rotating shaft 27 provided on one side of the support body 26 can rotate the servo motor 28 at multiple angles, which can facilitate subsequent driving, and thus can drive the tripod 30 to rotate. The storage and release chute 31 opened inside the tripod 30 can limit the position of the storage box side plate 32, and the slider inside the storage box side plate 32 can slide along the inside of the storage and release chute 31, which can adjust the angle of the storage box side plate 32 and automatically open the storage box side plate 32. Subsequently, start the motor inside the retractable ladder component 33 to deploy the retractable ladder component 33, which can facilitate the staff to climb and quickly pick up and place items. The retractable ladder component 33 can be retracted into the storage box body 20 to avoid waste of space and improve the practicality of the luggage rack body 4. At the same time, the extension rod 16 and the extension frame 17 cooperate to block items, which can prevent items from falling, and the reinforcing plate 18 has a certain slope to reduce air resistance.
