Description

Technical Field

[0001] This application relates to the field of roof box installation technology, and in particular to a stabilizing device for a roof box. Background Technology

[0002] A roof box is an enclosed storage device installed on the roof rack of a vehicle. It is also often called a roof box, roof storage box, or roof organizer. It is a special automotive exterior accessory that expands the vehicle's cargo space. Its core function is to store luggage, outdoor equipment, and other items, while also taking into account protection and wind resistance control.

[0003] Chinese Patent No. CN210027234U discloses a car roof box fixing structure, which includes a pair of longitudinal rails fixedly connected to the car roof and a roof box. The roof box is directly fixed to the longitudinal rails by fixing components. The fixing components include, from bottom to top, a lower limit fixing component, a middle limit support component, an upper limit fixing component, and a fixing component. The above technical solution has a simple and reliable structure, a simple installation process, greatly reduces the installation time required, and improves user satisfaction.

[0004] Regarding the aforementioned technologies, the existing technology uses the cooperation of a fastener and a first fixing screw to install the luggage box on the longitudinal rail. This requires the first fixing screw to be installed and removed every time the luggage box is loaded or unloaded, and the first fixing screw requires a specific tool to operate, which increases the number of steps for loading and unloading the roof luggage box and reduces the applicability of the roof luggage box fixing structure. Summary of the Invention

[0005] To improve the applicability of roof rack stabilizing devices, this application provides a roof rack stabilizing device.

[0006] This application provides a stabilizing device for a vehicle roof box, employing the following technical solution: A stabilizing device for a roof rack includes a mounting frame and a roof rack mounted on the roof. The roof rack includes a mounting box and a cover rotatably connected to the mounting box. A plurality of mounting beams are mounted on the mounting frame, and the roof rack is placed on the mounting beams. A limiting component is provided on the mounting beams. The limiting component includes a limiting rod, a rotating buckle, a limiting frame, and a fixing block. A sliding groove is provided on the mounting beams. One end of the limiting rod is rotatably connected to the sliding groove. A rotation-limiting component is provided in the sliding groove to limit the rotation of the limiting rod. The rotating buckle includes a rotating part and a connecting part. One end of the rotating part is rotatably connected to the cover, and one end of the connecting part is rotatably connected to the other end of the rotating part, forming a groove with the rotating part. The fixing block is connected to the mounting box. The limiting frame is U-shaped and connected to the mounting box. When locked, the fixing block is located in the groove, and the limiting rod is vertical, located between the limiting frame and the connecting part. A sealing component is provided on the limiting frame to limit the rotation of the connecting part.

[0007] By adopting the above technical solution, during installation, the luggage box is placed on the mounting beam, the limiting rod is flipped to a vertical position, and then the rotating part is flipped until the fixing block is in the slot and the connecting part is vertical. At this point, the limiting rod is located between the connecting part and the limiting frame. Finally, the sealing component is used to seal the limiting frame to restrict the rotation of the connecting part. The cooperation of the two limiting components achieves the effect of restricting the movement of the luggage box. During operation, it is only necessary to place the luggage box on the mounting beam, flip the rotating buckle to ensure that the fixing block is in the slot, and finally use the sealing component to restrict the rotation of the connecting part. The entire process does not require any other auxiliary tools and can be operated by the driver by hand. The steps are simple and quick, improving the applicability of the roof luggage box stabilization device compared to existing technologies.

[0008] Optionally, the rotation limiting assembly includes a sliding block, a pressure plate, and a locking bolt. The sliding groove is a T-shaped groove, and the sliding block is slidably fitted within the sliding groove. The sliding block has a rotation groove. One end of the limiting rod is provided with an eccentric part, and the limiting rod is rotatably connected to the rotation groove through the eccentric part. The pressure plate is disposed on the mounting beam and located above the sliding block. The locking bolt passes through the pressure plate and the sliding block and is threadedly engaged with the sliding block. When the limiting rod is in a vertical state, the limiting rod is in contact with the side wall of the rotation groove.

[0009] By adopting the above technical solution, during operation, the limiting rod is pushed to move the sliding block to the designated position. Then, the locking bolt is rotated to raise the sliding block to press against the top wall of the sliding groove, thereby restricting the movement of the sliding block. Then, the limiting rod is rotated to contact the side wall of the rotating groove, thereby preventing the limiting rod from continuing to rotate. At this time, the limiting rod is in a vertical state, achieving the effect of blocking the rotation of the limiting rod in one direction.

[0010] Optionally, a protrusion is connected to the connecting part, and a groove is opened on the fixing block. When the fixing block is located in the slot, the protrusion is located in the groove, and the connecting part is in a vertical state.

[0011] By adopting the above technical solution, the final angle of the connection is limited through the cooperation of the protrusions and grooves, which facilitates the subsequent locking operation and provides convenience and stability for the installation of the suitcase.

[0012] Optionally, the blocking assembly includes a limiting lock mounted on the limiting frame, and the connecting portion is located between the limiting lock and the limiting rod.

[0013] By adopting the above technical solution, when the connecting part is restricted from rotating, the restriction lock is installed at both ends of the restriction frame, so that a sealing space is formed inside the restriction frame. At this time, the connecting part and the restriction rod are both located inside the sealing space and are difficult to rotate, thus achieving the effect of restricting the rotation of the connecting part.

[0014] Optionally, the sealing assembly includes a sealing rod, a limiting block, and a pressure spring. Both ends of the limiting frame have mounting notches. Two limiting blocks are provided, each connected to the sealing rod. The limiting frame has a groove matching the shape of the limiting block. A fixing ring is connected to the sealing rod, and a clamping ring is also fitted onto the sealing rod. The pressure spring is fitted onto the sealing rod and located between the fixing ring and the clamping ring. When restricted, the sealing rod is located within the mounting notch, the limiting block is embedded in the groove, the clamping ring adheres to the side wall of the limiting frame away from the groove, and the pressure spring is in a compressed state.

[0015] By adopting the above technical solution, when sealing the connection part, the clamping ring is pressed against one side of the limiting frame, the pressure spring is compressed, and then the sealing rod is placed into the installation notch so that the limiting block is aligned with the groove. The sealing rod is released, and under the action of the pressure spring, the sealing rod moves, and the limiting block is embedded in the groove to restrict the movement of the sealing rod. At this time, a sealing space is formed between the sealing rod and the limiting frame. Both the connection part and the limiting rod are located in the sealing space, thereby achieving the effect of restricting the rotation of the connection part.

[0016] Optionally, a connecting rope is connected to one end of the limiting frame and the sealing rod.

[0017] By adopting the above technical solution, the connecting rope is used to assist in connecting the sealing rod, thus avoiding the possibility of the sealing rod being lost.

[0018] Optionally, when the connecting part is in the vertical state, there is a gap between it and the side wall of the mounting box. Several rubber posts are connected to the connecting part near the side wall of the mounting box, and the limiting rod is located within the gap when it is in the vertical state.

[0019] By adopting the above technical solution, during vehicle operation, there are situations involving sudden braking, sharp turns, and other rapid changes in direction. The luggage compartment, due to inertia, will exert pressure on the locking components. If the luggage compartment is rigidly locked, all the pressure will be concentrated on the locking components, potentially leading to deformation or damage over time. By setting a gap to increase the luggage compartment's buffer space, and by incorporating rubber pillars, when changing direction, the limiting bar impacts the rubber pillars. The friction between the luggage compartment and the mounting beam, along with the interaction between the limiting bar and the rubber pillars, reduces the impact force on the luggage compartment, limiting bar, and connecting parts. Compared to a rigid luggage compartment lock, this extends the service life of the roof rack limiting components.

[0020] Optionally, both sides of the limiting rod are connected to an extension edge, the mounting beam is provided with a stepped groove, and the end of the limiting rod is provided with a toggle ramp. When the extension edge is in contact with the stepped groove, the limiting rod is in a horizontal state.

[0021] By adopting the above technical solution, the cooperation between the extension plate and the step groove is used to position the angle of the limiting rod. When the limiting rod is in a horizontal state, the extension edge is located in the step groove, so that the limiting rod is flush with the surface of the mounting beam, and the installation of the suitcase will not be affected.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During installation, place the luggage box on the mounting beam, flip the limiting rod to make it vertical, then flip the rotating part until the fixing block is in the slot and the connecting part is vertical. At this point, the limiting rod is between the connecting part and the limiting frame. Finally, use the sealing component to seal the limiting frame to restrict the rotation of the connecting part. The cooperation of the two limiting components achieves the effect of restricting the movement of the luggage box. During operation, simply place the luggage box on the mounting beam, flip the rotating buckle to ensure that the fixing block is in the slot, and finally use the sealing component to restrict the rotation of the connecting part. The entire process does not require any other auxiliary tools and can be operated by the driver by hand. The steps are simple and quick, improving the applicability of the roof luggage box stabilization device compared to existing technologies. 2. When sealing the connection, press the clamping ring against one side of the limiting frame, compress the pressure spring, and then insert the sealing rod into the installation notch so that the limiting block is aligned with the groove. Release the sealing rod, and under the force of the pressure spring, the sealing rod moves, and the limiting block is embedded in the groove to restrict the movement of the sealing rod. At this time, a sealing space is formed between the sealing rod and the limiting frame. Both the connection and the limiting rod are located in the sealing space, achieving the effect of restricting the rotation of the connection. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0032] Embodiment 1 of this application discloses a stabilizing device for a roof rack. (See also...) Figure 1 and Figure 2 The roof luggage box stabilization device includes a mounting frame 1 and a luggage box 2 mounted on the roof. Several mounting beams 11 are mounted on the mounting frame 1; in this embodiment, two mounting beams 11 are provided. The luggage box 2 is placed on the mounting beams 11, and the luggage box 2 includes a mounting box 21 and a lid 22 hinged to the mounting box 21.

[0033] Reference Figure 2 , Figure 3 and Figure 4A limiting component 3 is provided on the mounting beam 11. The limiting component 3 includes a limiting rod 31, a rotating buckle 32, a limiting frame 33, and a fixing block 34. The rotating buckle 32 includes a rotating part 321 and a connecting part 322. One end of the rotating part 321 is hinged to the box cover 22, and the connecting part 322 is hinged to the other end of the rotating part 321, forming a groove 323 between them. The fixing block 34 is fixedly connected to the mounting box 21. The fixing block 34 is provided with a groove 341, and one end of the rotating part 321 is provided with a protrusion 3221.

[0034] Reference Figure 3 and Figure 4 The limiting frame 33 is U-shaped and is bolted to the side wall of the mounting box 21. The fixing block 34 is located in the slot 323, and the protrusion 3221 abuts against the inner wall of the groove 341. The connecting part 322 is vertical and located within the limiting frame 33. A gap is left between the connecting part 322 and the inner wall of the limiting frame 33. Several rubber pillars 3222 are fixedly connected to the connecting part 322 near the side wall of the mounting box 21. The gap is used to increase the buffer space of the luggage compartment 2, and the rubber pillars 3222 are used to buffer the impact on the luggage compartment 2 and the limiting rod 31.

[0035] Reference Figure 3 and Figure 5 A limited rotation assembly 4 is provided on the mounting beam 11. The limited rotation assembly 4 includes a sliding block 41, a pressure plate 42, and a locking bolt 43. A sliding groove, which is a T-shaped groove, is formed on the mounting beam 11. The sliding block 41 is slidably fitted in the sliding groove and has a rotation groove. The pressure plate 42 is set on the mounting beam 11 and is located above the sliding block 41. The locking bolt 43 passes through the pressure plate 42 and the sliding block 41 and is threadedly engaged with the sliding block 41. One end of the limiting rod 31 has an integrally formed eccentric part. The limiting rod 31 is hinged in the rotation groove through the eccentric part. When the limiting rod 31 is in the vertical state, it fits against the side wall of the rotation groove. The end of the limiting rod 31 is located between the inner wall of the limiting frame 33 and the connecting part 322.

[0036] Reference Figure 5 Both sides of the limiting rod 31 are fixedly connected to an extension edge 311. The mounting beam 11 has a stepped groove 111, and the end of the limiting rod 31 is provided with a toggle ramp 312. When the limiting rod 31 is in a horizontal state, the extension edge 311 is located in the stepped groove 111, and the toggle ramp 312 is used to assist the driver in operating the limiting rod 31.

[0037] Reference Figure 2 and Figure 3 A sealing component 5 is provided on the limiting frame 33. The sealing component 5 includes a limiting lock 51. Both ends of the limiting frame 33 have limiting holes. The locking part of the limiting lock 51 passes through the two limiting holes, so that a closed space is formed between the limiting lock 51 and the inner sidewall of the limiting frame 33. The limiting rod 31 and the connecting part 322 are both located in the closed space.

[0038] The implementation principle of the stabilizing device for a roof box in Embodiment 1 of this application is as follows: During installation, the sliding block 41 is moved to the designated position in advance, and then the sliding block 41 is locked with the locking bolt 43. Then, the luggage box 2 is placed on the mounting beam 11, and the limiting rod 31 is flipped until the limiting rod 31 touches the side wall of the rotating groove. The rotating buckle 32 is flipped so that the fixing block 34 is located in the slot 323 and the protrusion 3221 enters the buckle slot. At this time, the connecting part 322 is in a vertical state and is located in the limiting frame 33. Then, the limiting lock 51 is used to seal both ends of the limiting frame 33 to block the rotating part 321 and the limiting rod 31, thereby achieving the effect of restricting the movement of the luggage box 2.

[0039] During operation, simply place the luggage box 2 on the mounting beam 11, flip and rotate the buckle 32 to ensure that the fixing block 34 is located in the slot 323, and finally use the sealing component 5 to restrict the rotation of the connecting part 322. The whole process does not require the use of other auxiliary tools, and the driver can operate it by hand. The steps are simple and quick, which improves the applicability of the roof luggage box 2 stabilization device compared with the existing technology.

[0040] Example 2: The difference between this example and Example 1 is that the structure of the blocking component 5 is different.

[0041] Reference Figure 6 and Figure 7 The sealing assembly 5 includes a sealing rod 52, limiting blocks 53, and a pressure spring 54. Both ends of the limiting frame 33 have mounting notches 331, and grooves 332 are provided at the mounting notches 331. A connecting rope 521 is fixedly connected between the end of the sealing rod 52 and the limiting frame 33; the connecting rope 521 is used to prevent the sealing rod 52 from being lost. A fixing ring 522 is fixedly connected to the sealing rod 52, and a clamping ring 523 is sleeved on the sealing rod 52. The pressure spring 54 is sleeved on the sealing rod 52 and located between the fixing ring 522 and the clamping ring 523. Four limiting blocks 53 are provided, all fixedly connected to the sealing rod 52. Two limiting blocks 53 form a group, corresponding to one end of the limiting frame 33, and the shape of the limiting blocks 53 matches the groove 332.

[0042] When sealing the connection 322, first rotate the sealing rod 52 so that the limiting block 53 aligns with the mounting notch 331. Then, press the clamping ring 523 against the side wall of the limiting frame 33 away from the groove 332, compressing the pressure spring 54. Then, insert the sealing rod 52 into the mounting notch 331 and reverse the sealing rod 52. Under the force of the pressure spring 54, the sealing rod 52 moves, and the limiting block 53 enters the groove 332. A closed space is formed between the sealing rod 52 and the limiting frame 33, achieving the effect of sealing the connection 322.
