Description

Technical Field

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

[0002] A roof box is a device installed on the roof of a car to expand storage space. It offers advantages such as increased vehicle storage capacity, good sealing and protection, reduced interior crowding, and improved vehicle aesthetics. Because the roof box is located on top of the vehicle, a locking device is required to prevent its movement and ensure its safety.

[0003] Chinese Patent No. CN222005037U discloses a roof rack mounting device, which includes a roof rack with symmetrically arranged locking seats on its front and rear sides. A space for accommodating a luggage compartment is formed between two of the locking seats. The two locking seats are located on the front and rear sides of the luggage compartment, and they form a detachable locking mechanism with handles on the front and rear sides of the luggage compartment. This invention meets the requirements for quick installation and disassembly, has a robust fixing structure, is safe and theft-proof, has an attractive appearance, and is highly practical.

[0004] Regarding the aforementioned technologies, in the prior art, the luggage box is placed on the mounting base, the handle is flipped over to enter the limiting plate, and the adjusting screw is lowered by turning a tool to restrict the handle. Then, the baffle is embedded in two baffle locks to further restrict the handle, thus realizing the installation of the luggage box. However, the entire process requires adjusting the screw and installing the baffle. The installation of the baffle requires the cooperation of the lock and the baffle lock, and the cooperation requires a certain locking progress to achieve the effect of restricting the movement of the baffle. This setting increases the difficulty of baffle installation, reduces the installation efficiency of the roof luggage box, and reduces the applicability of the roof luggage box installation device. Summary of the Invention

[0005] To improve the applicability of roof box mounting devices, this application provides a locking device for roof boxes.

[0006] The locking device for a roof rack provided in this application adopts the following technical solution: A locking device for a roof rack includes a mounting bracket installed on the roof and a locking assembly installed on the roof rack. The mounting bracket has several sliding beams. The locking assembly includes a sliding block, a rod, and a limiting block. Each sliding beam has a T-shaped sliding groove with several inlets. Several sliding blocks are installed at the bottom of the roof rack, one sliding block corresponding to one inlet. Each limiting block has a limiting hole and is positioned within the sliding groove. A limiting assembly restricts the movement of the sliding block and the limiting block itself within the sliding groove. The rod extends vertically through the roof rack, and a control assembly on the roof rack controls the movement of the rod. During installation, the sliding block enters the sliding groove through the inlet, and the bottom end of the rod inserts into the limiting hole.

[0007] By adopting the above technical solution, during installation, the limiting block is first placed into the sliding groove, and the limiting component prevents the limiting block from moving. Then, the luggage box is placed on the sliding beam, and the sliding block enters the sliding groove through the inlet and moves a certain distance until the limiting component blocks the sliding block. Pressing the insertion rod causes it to descend and enter the limiting hole. By controlling the component to limit the movement of the insertion rod, the luggage box's freedom of movement is restricted, thus achieving the installation of the roof luggage box. By controlling the component to limit the movement of the insertion rod, the insertion rod is ensured to always be within the limiting hole. Combined with the limiting component blocking the sliding block, the horizontal freedom of the luggage box is restricted. In addition, the cooperation between the sliding block and the sliding groove restricts the vertical freedom of the luggage box. In actual operation, it is only necessary to place the luggage box on the sliding beam, move it a certain distance, and press the insertion rod to achieve the installation of the luggage box. Compared with the existing technology, the operation steps are fewer, the operation is easier, and the operation time is shorter, improving the installation efficiency of the roof luggage box and also improving the applicability of the roof luggage box installation device.

[0008] Optionally, the control component includes a mounting box, a toggle plate, limiting posts, and a first return spring. The luggage compartment has a mounting slot, and the mounting box is installed within the mounting slot. The mounting box has an insertion hole, and the insertion rod passes vertically through the insertion hole. Two limiting posts are provided, both fixedly connected to the insertion rod, forming a limiting ring groove between the two limiting posts. The first return spring is sleeved on the insertion rod and located between the lower limiting post and the bottom wall of the mounting box. The toggle plate is L-shaped and rotatably connected within the mounting box. The top of the mounting box has a toggle slot, and one end of the toggle plate passes through the toggle slot and extends outside the mounting box, while the other end is located on one side of the limiting ring groove. An intercepting block is connected to the inner side wall of the mounting box. A second return spring is installed between the toggle plate and the side wall of the mounting box. The toggle plate is located between the intercepting block and the second return spring. When the luggage compartment is locked, the other end of the toggle plate is located within the limiting ring groove.

[0009] By adopting the above technical solution, in the initial state, the other end of the lever abuts against the surface of the lower limiting post, and the second return spring is compressed; when the luggage is installed, the plug rod descends, the first return spring is compressed until the limiting ring groove aligns with the other end of the lever plate, the lever plate rotates in the opposite direction under the force of the second return spring, and the other end of the lever plate enters the limiting ring groove. At this time, the lever plate is in contact with the intercepting block, and the bottom end of the plug rod enters the limiting hole to restrict the reverse movement of the plug rod, thereby achieving the effect of controlling the movement of the plug rod.

[0010] Optionally, the mounting box includes a fixing box and a sealing plate. The fixing box has an installation notch that communicates with the insertion hole. The sealing plate is detachably connected to the fixing box. A connecting plate is fixedly connected to the sealing plate. The connecting plate has an arc surface. The insertion rod is located between the insertion hole and the arc surface. Rotating columns are connected to both sides of the actuating plate. The actuating plate is rotatably connected between the fixing box and the sealing plate through the rotating columns.

[0011] By adopting the above technical solution, the detachable sealing plate facilitates the smooth installation of the insertion rod and the toggle plate during installation, thereby improving the ease of operation of the entire control component.

[0012] Optionally, the limiting component includes a base block, a connecting block, and a locking bolt. The base block is disposed within the sliding groove, the sliding block is attached to the side wall of the base block and is located between the sliding block and the groove opening. Two connecting blocks are provided, one on the base block and the other on the limiting block. The locking bolt passes through the connecting block, one of which is threadedly engaged with the base block, and the other is threadedly engaged with the limiting block.

[0013] By adopting the above technical solution, when restricting movement, the locking bolt and connecting block work together to prevent the restricting block from moving, ensuring that the insert rod does not move, and to resist the sliding block, thus helping to restrict the horizontal movement of the suitcase and achieving the effect of restricting the horizontal movement of the suitcase.

[0014] Optionally, the limiting block is provided with a plurality of fixing teeth, and the connecting block is connected with a plurality of connecting teeth, wherein the connecting teeth and the fixing teeth mesh.

[0015] By adopting the above technical solution, the friction between the connecting block and the limiting block is improved through the meshing of the fixed teeth and the connecting teeth, further reducing the possibility of the suitcase moving.

[0016] Optionally, the end of the limiting block near the inlet is provided with an abutting slope, with the reference direction from bottom to top, and the length of the limiting block gradually decreases.

[0017] By adopting the above technical solution, the luggage is relatively heavy, and applying pressure to the sliding block makes it difficult for the sliding block to align with the slot, especially when the sliding block is partially located at the slot, which could cause it to get stuck. When the sliding block enters, it moves by resisting the inclined surface, reducing the possibility of friction between the sliding block and the side walls of the slot, making the sliding block enter the sliding groove more smoothly.

[0018] Optionally, the inner diameter of the limiting hole is larger than the diameter of the insertion rod.

[0019] The above technical solution does not provide perfect accuracy in determining the position of the limiting block, and errors are possible. If the inner diameter of the limiting hole matches the diameter of the insert rod, the position of the limiting block needs constant adjustment. Since the limiting block is located below the suitcase, this undoubtedly increases the difficulty of adjustment. Making the inner diameter of the limiting hole larger than the diameter of the insert rod allows the insert rod to smoothly enter the limiting hole within a reasonable margin of error, ultimately achieving the goal of quickly restricting the movement of the suitcase and improving the convenience of suitcase installation.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. During installation, the limiting block is first placed into the sliding groove, and the limiting component prevents the limiting block from moving. Then, the luggage box is placed on the sliding beam. The sliding block enters the sliding groove through the inlet and moves a certain distance until the limiting component blocks the sliding block. Pressing the insert rod causes it to descend and enter the limiting hole. By controlling the component to limit the movement of the insert rod, the luggage box's freedom of movement is restricted, thus achieving the installation of the roof luggage box. By controlling the component to limit the movement of the insert rod, the insert rod is ensured to always be within the limiting hole. Combined with the limiting component blocking the sliding block, the horizontal freedom of the luggage box is restricted. In addition, the cooperation between the sliding block and the sliding groove restricts the vertical freedom of the luggage box. In actual operation, simply placing the luggage box on the sliding beam, moving it a certain distance, and pressing the insert rod is sufficient to install the luggage box. Compared with existing technologies, this method has fewer steps, is easier to operate, and has a shorter operation time, improving the installation efficiency of the roof luggage box and enhancing the applicability of the roof luggage box installation device. 2. In the initial state, the other end of the lever abuts against the surface of the lower limiting post, and the second return spring is compressed. When the luggage is installed, the plug rod descends, the first return spring is compressed, until the limiting ring groove aligns with the other end of the lever plate. The lever plate rotates in the opposite direction under the force of the second return spring, and the other end of the lever plate enters the limiting ring groove. At this time, the lever plate is in contact with the intercepting block, and the bottom end of the plug rod enters the limiting hole to restrict the reverse movement of the plug rod, thereby achieving the effect of controlling the movement of the plug rod.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0029] This application discloses a locking device for a roof rack. (See also...) Figure 1 and Figure 2 The locking device for the roof box includes a fixed frame 1 mounted on the roof and a locking assembly 2 mounted on the roof box 01. The fixed frame 1 is a rectangular frame, and several sliding beams 11 are fixedly connected to the fixed frame 1 along its length. In this embodiment, two beams are used as an example. The top wall of the sliding beam 11 has a sliding groove 12 and several inlet openings 13 along its length. The sliding groove 12 is a T-shaped groove, and two inlet openings 13 are provided.

[0030] Reference Figure 2 , Figure 3 and Figure 4 The suitcase 01 is placed on the sliding beam 11. The locking assembly 2 includes a sliding block 21, a plug 22, and a limiting block 23. The plug 22 is vertically inserted into the suitcase 01, and the suitcase 01 has two mounting slots inside, which are aligned with the sliding beam 11. A control assembly 3 is installed in the mounting slot, which includes a mounting box 31, a toggle plate 32, a limiting post 33, and a first return spring 34.

[0031] Reference Figure 3 and Figure 4The mounting box 31 includes a fixing box 311 and a sealing plate 312. The fixing box 311 is bolted to the mounting groove. The fixing box 311 has an insertion hole and a mounting notch 3111 connecting the insertion hole. The insertion rod 22 passes through the insertion hole. A connecting plate 3121 is fixedly connected to the sealing plate 312. The connecting plate 3121 has an arc surface. The sealing plate 312 is bolted to the fixing box 311. The connecting plate 3121 enters the mounting notch 3111, and the arc surface fits against the surface of the insertion rod 22. Two limiting posts 33 are provided, both of which are fixedly connected to the insertion rod 22. A limiting ring groove 331 is formed between the two limiting posts 33. A first return spring 34 is sleeved on the insertion rod 22 and is located between the lower limiting post 33 and the inner bottom wall of the fixing box 311.

[0032] Reference Figure 3 and Figure 4 The fixed box 311 has a toggle groove 3112, and the toggle plate 32 is L-shaped. Rotating columns are fixedly connected to both sides of the fixed plate, which is rotatably connected between the sealing plate 312 and the fixed box 311 via these columns. One end of the toggle plate 32 passes through the toggle groove 3112 and extends beyond the fixed box 311. The other end of the toggle plate 32 normally abuts against the surface of the upper limiting column 33. A second return spring 3113 is installed between the toggle plate 32 and the inner wall of the fixed box 311. An intercepting block 3114 is fixedly connected to the inner wall of the fixed box 311, and the intercepting block 3114 is located on the rotation path of the toggle plate 32.

[0033] Reference Figure 2 , Figure 5 and Figure 6 The shape of the sliding block 21 matches the sliding groove 12. Four sliding blocks 21 are provided, arranged in pairs, and in a straight line. Both sliding blocks 21 are bolted to the bottom wall of the luggage compartment 01. The sliding blocks 21 slide within the sliding groove 12. A limiting component 4 is provided on the sliding beam 11. The limiting component 4 includes a base block 41, a connecting block 42, and a locking bolt 43. The base block 41 is located within the sliding groove 12 and fits against the sliding block 21.

[0034] Reference Figure 5 and Figure 6 A limiting block 23 is disposed within the sliding groove 12. The inlet 13 is located between the limiting block 23 and the bottom block 41. An abutting inclined surface 231 is provided at the end of the limiting block 23 near the inlet 13. With the reference direction from bottom to top, the length of the limiting block 23 gradually decreases. The abutting inclined surface 231 assists the sliding block 21 in entering the inlet 13. A limiting hole 232 is formed on the limiting block 23. The diameter of the limiting hole 232 is larger than the diameter of the insertion rod 22, and the limiting block 23 is aligned with the insertion rod 22. Several fixing teeth 233 are fixedly connected to the limiting block 23.

[0035] Reference Figure 5 and Figure 6Two connecting blocks 42 are provided, one on the bottom block 41 and the other on the limiting block 23. Both connecting blocks 42 are located on the top wall of the sliding beam 11. Several connecting teeth 421 are fixedly connected to the bottom wall of the connecting block 42 on the limiting block 23. The fixing teeth 233 and the connecting teeth 421 mesh, increasing the friction between the connecting block 42 and the limiting block 23. Locking bolts 43 pass through the connecting blocks 42; one locking bolt 43 is threaded into the bottom block 41, and the other is threaded into the limiting block 23.

[0036] The implementation principle of a locking device for a roof box according to an embodiment of this application is as follows: Before installing the roof box 01, the limiting block 23 and the bottom block 41 are moved to the designated position of the sliding groove 12. Then, the limiting block 23 and the bottom block 41 are tightened with the locking bolt 43 so that the contact slope 231 is within the range of the inlet 13. Then, the roof box 01 is placed on the sliding beam 11. The sliding block 21 is guided into the inlet 13 through the contact slope 231 and moves one end until it contacts the bottom block 41. The roof box 01 is opened and the insert rod 22 is pressed. The insert rod 22 descends and the first return spring 34 is compressed until the bottom end of the insert rod 22 enters the limiting hole 232. At this time, the limiting ring groove 331 is aligned with the other end of the actuating plate 32 and rotates under the force of the second return spring 3113 until it contacts the intercepting block 3114. At this time, the other end of the actuating plate 32 enters the limiting ring groove 331, thereby limiting the movement of the insert rod 22 and realizing the installation of the roof box 01.

[0037] By controlling component 3 to restrict the movement of the insert rod 22, it is ensured that the insert rod 22 is always within the limiting hole 232. Combined with the blocking block 21 of the limiting component 4, the horizontal freedom of the luggage box 01 is restricted. In addition, the cooperation between the sliding block 21 and the sliding groove 12 restricts the vertical freedom of the luggage box 01. In actual operation, the luggage box 01 only needs to be placed on the sliding beam 11, moved a certain distance, and the insert rod 22 to realize the installation of the luggage box 01. Compared with the existing technology, there are fewer operation steps, the operation is easier and the operation time is shorter, which improves the installation efficiency of the roof luggage box 01 and also improves the applicability of the roof luggage box 01 installation device.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
