The installation process is cumbersome and time-consuming, especially when the luggage box needs to be installed urgently before the trip. This complicated installation method brings great inconvenience to the user. Utility Model Content

[0004] The purpose of this utility model is to provide a roof box with a quick assembly structure to solve the problem that the installation of the above-mentioned roof box often requires the use of multiple tools and complicated bolt tightening methods to fix it to the roof rack.

[0005] The present invention achieves the above objectives through the following technical solution: a roof box with a quick assembly structure, comprising a roof mounting frame and a roof box disposed on the surface of the roof mounting frame;

[0006] A connecting pressure plate is installed on the surface of the roof mounting bracket. A wedge block is symmetrically installed on the bottom surface of the connecting pressure plate. A fixing sleeve is fixed on the surface of the roof mounting bracket. A fixing rod is fixed inside the fixing sleeve. Two sliders are slidably connected to the surface of the fixing rod. A wedge seat is installed on the surface of each slider. A clamping block is installed on the bottom surface of each slider. The two wedge seats and the two clamping blocks are symmetrically arranged. When the roof box is installed, the two clamping blocks clamp the surface of the roof mounting bracket.

[0007] As a further embodiment of this utility model: two springs are sleeved on the surface of the fixed rod and between the two sliders. One end of each spring abuts against the two sliders, and the ends of the two springs that are close to each other abut against the protrusion at the center of the fixed rod.

[0008] As a further embodiment of this utility model: a guide rod is fixed on the bottom surface of the roof box, and a guide slot adapted to the guide rod is opened on the surface of the roof mounting frame. The roof box is slidably inserted into the surface of the roof mounting frame through the guide rod and the guide slot.

[0009] As a further embodiment of this utility model: a sliding rod is installed in the groove opened on the surface of the roof mounting bracket, a control slider is slidably connected to the surface of the sliding rod, a locking wedge is fixed on one side of the control slider, and an L-shaped limiting plate is fixed on the bottom surface of the roof box. When the roof box is connected to the roof mounting bracket, the L-shaped limiting plate abuts against the inclined surface of the locking wedge and is locked by the bottom plane of the locking wedge.

[0010] As a further embodiment of this utility model: a second spring is sleeved on the surface of the slide rod, one end of the second spring abuts against a groove opened on the surface of the roof mounting bracket, and the other end of the second spring abuts against the surface of the control slider.

[0011] As a further embodiment of this utility model: a fixing block is fixed to the surface of the roof mounting bracket, and a locking bolt is provided on the surface of the fixing block. After the roof box is connected with the roof mounting bracket, it is fixed in place by the locking bolt provided in the fixing block.

[0012] The beneficial effects of this utility model are:

[0013] This utility model utilizes a combination of structures including a fixed sleeve, a fixed rod, a clamping block, a wedge seat, a wedge block, a guide rod, a guide slot, a locking wedge block, an L-shaped limiting plate, and locking bolts. The roof box is lifted, and its bottom guide rod is precisely aligned with the guide slot on the roof mounting frame surface. The roof box is pushed along the guide slot. As the roof box approaches and presses down, the L-shaped limiting plate on the bottom of the roof box interacts with the locking wedge block, automatically locking it horizontally. The downward pressure of the roof box is converted into a force that pushes the slider to slide to both sides through the inclined surfaces of the wedge block and the wedge seat, causing the clamping block to quickly clamp the roof mounting frame, achieving initial vertical fixation. This significantly shortens installation time and reduces installation difficulty.

[0014] The matching design of the guide rod and guide slot provides users with intuitive and clear installation direction guidance. This design allows users to easily connect the roof box to the roof mounting bracket when installing the roof box, effectively avoiding problems in subsequent fixing steps due to installation position deviation, and ensuring that the entire installation process is accurate and efficient.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example 1

[0024] like Figures 1 to 7 As shown, a roof box with a quick-assembly structure includes a roof mounting bracket 1 and a roof box 2 disposed on the surface of the roof mounting bracket 1.

[0025] A connecting pressure plate 9 is installed on the surface of the roof mounting bracket 1. A wedge block 10 is symmetrically installed on the bottom surface of the connecting pressure plate 9. A fixing sleeve 3 is fixed on the surface of the roof mounting bracket 1. A fixing rod 4 is fixed inside the fixing sleeve 3. Two sliders 6 are slidably connected to the surface of the fixing rod 4. A wedge seat 8 is installed on the surface of each slider 6. A clamping block 7 is installed on the bottom surface of each slider 6. The two wedge seats 8 and the two clamping blocks 7 are symmetrically arranged. When the roof box 2 is installed, the two clamping blocks 7 are clamped on the surface of the roof mounting bracket 1.

[0026] When installing the roof box 2, the user only needs to align and place it down. The downward pressure of the roof box 2 is automatically converted into a force that pushes the slider 6 to slide to both sides through the cooperation of the wedge block 10 and the inclined surface of the wedge seat 8. This, in turn, drives the clamping block 7 to quickly clamp the roof mounting bracket 1. There is no need for complicated bolt tightening operations, which greatly shortens the installation time. The two symmetrically arranged clamping blocks 7 apply clamping force to the roof mounting bracket 1 from both sides at the same time, which can evenly distribute the weight of the roof box 2. This ensures that the roof box 2 will not shake or shift due to uneven force during vehicle operation. Even when facing bumpy roads or airflow impact at high speeds, it can maintain stability and effectively improve driving safety. When disassembling, the user lifts the roof box 2 upwards. The pressure of the wedge block 10 and the wedge seat 8 disappears, and the spring 5 pushes the slider 6 to automatically release the clamping block 7, making it easy to remove the roof box 2. The entire disassembly process is simple and smooth, improving the user experience.

[0027] Furthermore, two springs 5 ​​are fitted on the surface of the fixed rod 4 and between the two sliders 6. One end of each spring 5 abuts against the two sliders 6, and the ends of the two springs 5 ​​that are close to each other abut against the protrusion at the center of the fixed rod 4.

[0028] When removing the roof box 2, as the roof box 2 is lifted upwards, the pressure between the wedge block 10 and the wedge seat 8 disappears, and the spring 5, which is in a compressed state, will instantly release its elastic force. The two springs 5 ​​push the slider 6 to both sides, causing the clamping block 7 to move quickly towards the center, quickly releasing the clamping force on the surface of the roof mounting bracket 1, greatly improving the convenience of disassembly and reducing the force and time required for disassembly by the user.

[0029] Furthermore, a guide rod 11 is fixed to the bottom surface of the roof box 2, and a guide slot 12 adapted to the guide rod 11 is provided on the surface of the roof mounting frame 1. The roof box 2 is slidably inserted into the surface of the roof mounting frame 1 through the guide rod 11 and the guide slot 12.

[0030] The matching design of the guide rod 11 and the guide slot 12 provides users with clear and accurate installation direction guidance when installing the roof box 2. Users only need to align the guide rod 11 with the guide slot 12 to easily connect the roof box 2 with the roof mounting bracket 1, which greatly reduces the installation difficulty and avoids problems in subsequent fixing steps due to installation position deviation, ensuring the accuracy and efficiency of the installation process. Example 2

[0031] Improvements based on Example 1:

[0032] Furthermore, a slide rod 13 is installed in the groove opened on the surface of the roof mounting bracket 1. A control slider 14 is slidably connected to the surface of the slide rod 13. A locking wedge 16 is fixed on one side of the control slider 14. An L-shaped limiting plate 17 is fixed on the bottom surface of the roof box 2. When the roof box 2 is docked with the roof mounting bracket 1, the L-shaped limiting plate 17 abuts against the inclined surface of the locking wedge 16 and is locked by the bottom plane of the locking wedge 16.

[0033] When the roof box 2 approaches the roof mounting bracket 1, the L-shaped limiting plate 17 contacts the inclined surface of the locking wedge 16 and slides along it until it is locked by the bottom plane of the locking wedge 16. This process ensures that the roof box 2 is accurately positioned in the horizontal direction, preventing displacement during subsequent fixing operations and providing a stable reference for the clamping action of the subsequent clamping block 7, thus ensuring the accuracy and stability of the entire installation structure. When installing the roof box 2, the user only needs to align the roof box 2 with the roof mounting bracket 1 and put it down. The interaction between the L-shaped limiting plate 17 and the locking wedge 16 will automatically complete the horizontal locking without additional positioning operations or complex alignment procedures. This automatic locking mechanism greatly simplifies the installation process, reduces the installation difficulty, and saves the user's installation time and effort.

[0034] Furthermore, a second spring 15 is fitted onto the surface of the slide rod 13. One end of the second spring 15 abuts against a groove on the surface of the roof mounting bracket 1, and the other end abuts against the surface of the control slider 14. When the roof box 2 is installed, after the L-shaped limiting plate 17 passes over the inclined surface of the locking wedge block 16 and is locked by the bottom plane, the second spring 15 will automatically push the control slider 14 forward, keeping the locking wedge block 16 locked to the L-shaped limiting plate 17. During disassembly, after manually pushing the control slider 14 to overcome the elastic force of the second spring 15, once the control slider 14 is released, the second spring 15 can quickly return it to its initial position, preparing it for the next installation or disassembly, greatly improving the continuity and convenience of operation.

[0035] Furthermore, a fixing block 18 is fixed to the surface of the roof mounting bracket 1, and a locking bolt 19 is provided on the surface of the fixing block 18. After the roof box 2 is connected to the roof mounting bracket 1, it is fixed in place by the locking bolt 19 provided in the fixing block 18.

[0036] After the roof box 2 is initially installed using the guide rod 11, L-shaped limiting plate 17, and clamping block 7, the locking bolt 19 can further strengthen the connection between the roof box 2 and the roof mounting bracket 1, effectively preventing the roof box 2 from loosening or shifting, greatly improving the overall stability of the roof box 2 after installation, and ensuring driving safety.

[0037] Working principle: First, securely install the roof mount 1 onto the vehicle roof according to the vehicle's compatibility requirements. Pick up the roof box 2 and align the pre-fixed guide rod 11 on its bottom surface with the guide slot 12 on the surface of the roof mount 1. Slowly move the roof box 2 towards the roof mount 1 and push it along the direction of the guide slot 12.

[0038] Continue pressing down on the roof box 2. At this time, the weight of the roof box 2 is transmitted to the roof mounting bracket 1 through the guide rod 11 and the L-shaped limiting plate 17. At the same time, the downward pressure of the roof box 2 is transmitted to the wedge seat 8 through the wedge block 10. Due to the inclined surface cooperation of the wedge block 10 and the wedge seat 8, a horizontal component force is generated, which causes the two sliders 6 to slide along the fixed rod 4 to both sides, thereby driving the clamping block 7 to move to both sides. The clamping block 7 contacts the surface of the roof mounting bracket 1 and gradually clamps it, thereby achieving the initial fixation of the roof box 2 in the vertical direction.

[0039] As the roof box 2 approaches, the L-shaped limiting plate 17 on the bottom surface of the roof box 2 begins to contact the inclined surface of the locking wedge 16. Due to the movement of the L-shaped limiting plate 17, a horizontal component force is generated on the locking wedge 16, causing the control slider 14 to slide backward along the slide rod 13 against the elastic force of the second spring 15. When the roof box 2 continues to move downward, the L-shaped limiting plate 17 passes over the inclined surface of the locking wedge 16 and reaches the bottom plane of the locking wedge 16. At this time, the second spring 15 pushes the control slider 14 to slide forward, so that the bottom plane of the locking wedge 16 locks the L-shaped limiting plate 17. At this time, the roof box 2 is initially positioned in the horizontal direction.

[0040] After the clamping block 7 fully clamps the roof mounting bracket 1, the locking bolt 19 on the fixing block 18 is rotated to make its end make close contact with the bottom surface of the roof box 2 and apply pressure, thereby further fixing the roof box 2 firmly to the roof mounting bracket 1. At this point, the installation of the roof box 2 is completed.

[0041] The process of removing the roof box: First, loosen the locking bolt 19 on the fixing block 18 so that its end is no longer in contact with the bottom surface of the roof box 2, thus releasing the additional fastening force on the roof box 2. Manually push the control slider 14 backward so that it slides backward along the slide rod 13 against the elastic force of the second spring 15. As the control slider 14 moves, the locking wedge 16 also moves backward, thereby releasing the lock on the L-shaped limit plate 17. Lift the roof box 2 upward. At this time, the pressure between the wedge 10 and the wedge seat 8 disappears. Under the elastic force of the first spring 5, the two sliders 6 slide along the fixing rod 4 towards the middle, driving the clamping block 7 to move towards the middle, releasing the clamping on the surface of the roof mounting bracket 1. Continue to lift the roof box 2 upward so that the guide rod 11 on its bottom surface is completely pulled out from the guide slot 12 on the surface of the roof mounting bracket 1. The roof box 2 can then be removed from the roof mounting bracket 1.
