Description

Technical Field

[0001] The utility model relates to the technical field of roof racks, in particular to an adjustable roof rack mounting mechanism. Background Art

[0002] An automobile roof rack, also known as a roof luggage rack, is a support frame or component installed on the top of the vehicle body, mainly used for safely and conveniently fixing luggage. This device is usually used on models such as hatchback wagons, SUVs, and MPVs, aiming to solve the problem of insufficient interior space. Through the roof rack, larger items such as luggage, bicycles, and folding beds can be carried. The roof rack not only plays a decorative and aesthetic role, but more importantly, it can hold things that cannot be placed in the luggage compartment, thereby increasing the interior space and improving the load-carrying capacity of the vehicle.

[0003] Currently, most of the crossbars for placing luggage on some roof racks are supported by mounting seats at both ends. However, during use, due to the limitation of the vehicle roof, some luggage racks often need to be assembled as a whole and then installed on the roof of the vehicle. When it is necessary to repair one of the mounting seats, due to limited space, the entire roof rack can only be disassembled, and then the mounting seat can be disassembled separately for repair. This makes the installation and disassembly time longer and reduces the repair efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and propose an adjustable roof rack mounting mechanism.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The adjustable roof rack mounting mechanism includes a flush crossbar mechanism. The flush crossbar mechanism includes a crossbar. A cavity is formed inside the crossbar. A rubber strip is embedded on the top surface of the crossbar, and limiting openings are formed on the bottom surfaces at both ends. Flush crossbar mounting seats are inserted at both ends of the crossbar.

[0007] The flush crossbar mounting seat includes a mounting bottom shell. An installation opening is formed on the mounting bottom shell. The shell at the installation opening of the mounting bottom shell is inserted at both ends of the crossbar. A limiting unit is arranged at the installation opening and can be inserted into the cavity of the crossbar.

[0008] The limiting unit includes a telescopic support rod. A limiting support is arranged on the upper surface of the telescopic support rod. An inner hexagon socket head screw is arranged on the telescopic support rod. A second spring is sleeved outside the cylinder of the inner hexagon socket head screw on the telescopic support rod. One end of the second spring is fixedly connected to the side wall of the limiting support, and the other end of the second spring away from the limiting support is fixedly connected to the side wall of the plate body on one side of the telescopic support rod.

[0009] In addition, a preferred structure is that a clamping mechanism is provided on the upper surface of one end of the telescopic support rod. The clamping mechanism includes a clamping block pin. Clamping blocks are symmetrically and rotatably installed on the upper and lower sides of the clamping block pin shaft body. The clamping blocks can contact the two side walls of the inner cavity of the cross bar. A clamping reset block is installed between the clamping blocks.

[0010] In addition, a preferred structure is that positioning installation heads are symmetrically provided on the bottom surface of the clamping reset block, and the clamping reset block is clamped at the through holes of the two side clamping blocks.

[0011] In addition, a preferred structure is that a resisting plate is provided on the upper surface of the telescopic support rod. The resisting plate resists the two side clamping blocks. An axle pin activity opening is formed on the upper surface of the telescopic support rod. The clamping block pin is arranged at the axle pin activity opening. A limiting seat activity opening is formed on one side of the axle pin activity opening on the upper surface of the telescopic support rod. A limiting support seat is arranged at the limiting seat activity opening.

[0012] In addition, a preferred structure is that an upper cover is installed on the upper surface of the installation bottom shell. A rotating support is installed in the cavity of the installation bottom shell. A support plate is installed on the upper surface of the rotating support. The hexagon socket head cap screw passes through the support plate.

[0013] In addition, a preferred structure is that a rubber pad is installed on the bottom surface of the rotating support. A blocking block is installed at the bottom of the rotating support. A hook is clamped on the upper surface of the support plate.

[0014] In addition, a preferred structure is that an activity groove is formed on the upper surface of the limiting support seat body. A limiting convex block is movably arranged at the activity groove. Springs are symmetrically arranged at the top of the limiting convex block. One end of the spring is arranged at the top of the limiting convex block, and the other end of the spring away from the limiting convex block abuts against the top wall in the activity groove. The limiting convex block can be buckled into the limiting opening. An installation groove is formed on one side of the activity groove on the upper surface of the limiting support seat.

[0015] The beneficial effects of the present utility model are as follows: By setting the flush cross bar mounting seat for fixing the cross bar as a plug-in type, the installation and disassembly process becomes more convenient, without the need to disassemble the fixing components. Moreover, the set limiting unit ensures the firmness of the plug board. And through the set second spring, the limiting support seat can move, so that the clamping mechanism on one side can move accordingly. In this way, the cross bar inserted into the installation bottom shell can be contracted by a certain distance. Thus, when disassembling and installing, after the cross bar is contracted by a certain distance, the distance between the two side flush cross bar mounting seats can be adjusted. By adjusting the distance, space is created to facilitate the disassembly of the flush cross bar mounting seat. In this way, it is realized that the entire luggage rack does not need to be disassembled during maintenance, effectively improving the efficiency of disassembly and installation.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Refer to Figure 1-14 , an adjustable roof luggage rack mounting mechanism, including a flush crossbar mechanism 1, characterized in that the flush crossbar mechanism 1 includes a crossbar 11, a cavity is opened in the crossbar 11, and flush crossbar mounting seats 2 are inserted at both ends of the crossbar 11. The flush crossbar mounting seat 2 includes a mounting bottom shell 21, and a mounting opening 211 is opened in the mounting bottom shell 21. The shell at the mounting opening 211 of the mounting bottom shell 21 is inserted at both ends of the crossbar 11. A limiting unit 3 is arranged at the mounting opening 211. The limiting unit 3 can be inserted into the cavity of the crossbar 11, and the limiting unit 3 is used to improve the firmness of the mounting bottom shell 21 inserted on both sides of the crossbar 11.

[0033] In addition, the limiting unit 3 includes a telescopic support rod 31. A limiting support 7 is arranged on the upper surface of the telescopic support rod 31, and an inner hexagon socket head screw 8 is arranged on the telescopic support rod 31. A second spring 9 is sleeved outside the cylinder of the inner hexagon socket head screw 8 on the telescopic support rod 31. One end of the second spring 9 is fixedly connected to the side wall of the limiting support 7, and the other end of the second spring 9 away from the limiting support 7 is fixedly connected to the side wall of the plate body on one side of the telescopic support rod 31. The second spring 9 enables the limiting support 7 to release elastic potential energy and reset after contraction.

[0034] Among them, a clamping mechanism 32 is arranged on the upper surface of one end of the telescopic support rod 31. The clamping mechanism 32 includes a clamping block pin 321. Clamping blocks 322 are symmetrically rotatably installed on the upper and lower sides of the shaft of the clamping block pin 321. The clamping blocks 322 can contact the side walls on both sides of the inner cavity of the crossbar 11, and a clamping reset block 33 is installed between the clamping blocks 322.

[0035] Moreover, positioning mounting heads 331 are symmetrically arranged on the bottom surface of the clamping reset block 33. The clamping reset block 33 is clamped at the through holes of the two clamping blocks 322. A pressing plate 311 is arranged on the upper surface of the telescopic support rod 31. The pressing plate 311 presses against the two clamping blocks 322. A pin moving opening 312 is opened on the upper surface of the telescopic support rod 31. The clamping block pin 321 is arranged at the pin moving opening 312. A limiting seat moving opening 313 is opened on one side of the pin moving opening 312 on the upper surface of the telescopic support rod 31. The limiting support 7 is arranged at the limiting seat moving opening 313. The pressing plate 311 can limit the moving range of the clamping blocks 322.

[0036] Moreover, an upper cover 22 is installed on the upper surface of the mounting bottom case 21. A rotary support 6 is installed in the cavity of the mounting bottom case 21. A support plate 10 is installed on the upper surface of the rotary support 6. An internal hexagonal socket head screw 8 passes through the support plate 10. One end of the internal hexagonal socket head screw 8 is fixed at the clamping block pin 321, and the other end is movably arranged at the support plate 10.

[0037] In addition, a rubber pad 5 is installed on the bottom surface of the rotary support 6. A plugging block 4 is installed at the bottom of the rotary support 6. A hook 001 is clamped on the upper surface of the support plate 10. The hook 001 is used to be fixed on the car roof.

[0038] Among them, an activity groove 72 is formed on the upper surface of the seat body of the limit support 7. A limit convex block 74 is movably arranged in the activity groove 72. Springs 73 are symmetrically arranged on the top of the limit convex block 74. One end of the spring 73 is arranged on the top of the limit convex block 74, and the other end of the spring 73 away from the limit convex block 74 abuts against the top wall in the activity groove 72. The limit convex block 74 can be buckled into the limit port 111. An installation groove 71 is formed on the upper surface of the limit support 7 on one side of the activity groove 72.

[0039] In this embodiment, when the luggage rack is integrally installed on the car roof, first install the flush crossbar mechanism 1, embed the rubber strip 12 into the groove on the top of the crossbar 11, then insert the crossbar 11 into the two side installation openings 211, and make the limit unit 3 insert into both sides of the cavity of the crossbar 11.

[0040] After the limit unit 3 is inserted into the two side cavities of the crossbar 11, after the limit unit 3 is inserted, the limit convex block 74 at the bottom of the limit support 7 is squeezed by the inner cavity bottom wall of the crossbar 11, so that the limit convex block 74 can be squeezed into the activity groove 72, and the spring 73 can also contract. Then the telescopic rod 31 slides in the crossbar 11. Once the limit convex block 74 slides to the limit port 111 inside the crossbar 11, the limit convex block 74 is no longer restricted by the inner cavity bottom wall of the crossbar 11. At this time, the spring 73 releases its elastic potential energy, pushes the limit convex block 74 out of the activity groove 72, so that it is stuck at the limit port 111, thereby fixing the limit unit 3.

[0041] When the limit unit 3 is inserted into the inner cavity of the crossbar 11, the clamping block 322 cooperates with the clamping block pin 321, so that when the limit unit 3 is inserted into the inner cavity of the crossbar 11, the clamping block 322 can be clamped on the inner wall of the two side cavities of the crossbar 11, and it can be adjusted through the set fixing part 6. Moreover, the middle clamping and resetting block 33 is made of a material including but not limited to rubber, so that the cooperation with the abutting plate 311 restricts the movement range of the clamping and resetting block 33. In this way, when the flush crossbar mounting seat 2 is installed into the two side crossbars 11, no fixing parts are required for installation, and the disassembly process only requires simple plugging and unplugging, and its firmness is also good.

[0042] Moreover, the second spring 9 is provided to enable the limit support 7 to move, so that the clamping mechanism 32 on one side can move accordingly. In this way, the cross bar 11 inserted into the mounting bottom case 21 can contract a certain distance. Thus, when disassembling and installing, after the cross bar 11 contracts a certain distance, the distance between the flush cross bar mounting seats 2 on both sides can be adjusted, and the space can be created by adjusting the distance to facilitate the removal of the flush cross bar mounting seats 2.

[0043] And by installing the fixing hook 001 onto the support plate 10 and then covering it with the upper cover 22, or a binding strap 002 can be installed. By removing the plugging block 4, then passing through the rotating support 6 and installing it onto the support plate 10. Moreover, the rotating support 6 can swing by a certain angle, enabling the hook 001 or the binding strap 002 to swing by a certain angle, thus increasing its versatility.

[0044] In the present utility model, the flush cross bar mounting seat 2 for fixing the cross bar 11 is set as a plug-in type, making the installation and disassembly process more convenient without the need to disassemble the fixing components. Moreover, the provided limit unit 3 ensures the firmness of the inserted plate. And the second spring 9 is provided to enable the limit support 7 to move, so that the clamping mechanism 32 on one side can move accordingly. In this way, the cross bar 11 inserted into the mounting bottom case 21 can contract a certain distance. Thus, when disassembling and installing, after the cross bar 11 contracts a certain distance, the distance between the flush cross bar mounting seats 2 on both sides can be adjusted, and the space can be created by adjusting the distance to facilitate the removal of the flush cross bar mounting seats 2. In this way, it is not necessary to disassemble the entire luggage rack during maintenance, effectively improving the efficiency of disassembly and installation.

[0045] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
