Description

Technical Field

[0001] This utility model belongs to the technical field of car roof rack brackets, specifically relating to a detachable car roof rack bracket. Background Technology

[0002] A car roof rack is a bracket installed on the roof of a vehicle to secure large items. It's a basic component of the roof support system, primarily expanding the vehicle's cargo space. Commonly found in SUVs and MPVs, it works in conjunction with roof boxes and roof frames to carry luggage, bicycles, skis, and other items. Over 50 brands offer related products on the market. Before installation, confirm whether your vehicle model has pre-installed interfaces. Adding a roof rack to a vehicle without pre-installed interfaces may compromise safety and sealing. When purchasing, pay attention to safety certifications, load limits (usually 30-50 kg), and compatibility. During use, regularly check the tightness of the screws, avoid overloading or emergency braking, and ensure the cargo is evenly secured. According to regulations, the cargo height from the roof cannot exceed 0.5 meters. After installation, it must be registered with the vehicle management department, and the installation must comply with vehicle size specifications. However, existing car roof rack brackets are not flexible enough. They cannot change their volume depending on whether luggage is loaded or not, nor can they adjust their volume according to the size of the luggage, resulting in low loading efficiency. Therefore, it is of great importance to design a detachable car roof rack bracket to solve the above defects. Utility Model Content

[0003] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a detachable car roof rack bracket. This main body solves the problem that existing car roof rack brackets are not flexible enough, cannot change their volume according to whether luggage is loaded, and cannot adjust their volume according to the size of the luggage, resulting in low loading efficiency.

[0004] (2) Technical solution To solve the aforementioned technical problems, this utility model provides a detachable car roof rack bracket, which includes a main body. Two sets of opposing mounting blocks are fixedly connected inside the main body. Each of the two sets of mounting blocks has two sets of mounting holes on their respective sides. A first crossbar is slidably connected inside each mounting block. A first rotating block is fixedly connected to the respective ends of the two sets of first crossbars within the same set of mounting blocks, which are far apart from each other. A first rotating rod is rotatably connected to the respective sides of the two sets of first rotating blocks in the same row, which are close to each other. A first vertical rod is slidably connected to the interior of the first rotating rod, at its end away from the first rotating block. A second rotating block is fixedly connected to the end of the first vertical rod away from the first rotating rod. Two sets of second rotating blocks in the same column are rotatably connected to a third rotating block at their closest points. Two sets of third rotating blocks in the same row are fixedly connected to a second horizontal bar at their closest points. Two sets of second horizontal bars in the same row are slidably connected via a first moving block. Two sets of third rotating blocks in the same column are rotatably connected to a second rotating rod at their closest points. A second vertical bar is slidably connected inside the second rotating rod. A fourth rotating block is fixedly connected to the end of the second vertical bar away from the second rotating rod. Two sets of fourth rotating blocks in the same column are rotatably connected to a fifth rotating block at their closest points. Two sets of fifth rotating blocks in the same row are fixedly connected to a third horizontal bar at their closest points. Two sets of third horizontal bars in the same row are slidably connected via a second moving block.

[0005] When using the main body of this technical solution, two sets of mounting blocks are installed on the roof of the car through mounting holes, facilitating overall disassembly. When luggage is not needed, the first moving block, the second moving block, the first rotating rod, and the second rotating rod are all flush with the mounting blocks and close to the roof, thus retracting the main body, reducing its volume, reducing wind resistance, and making the car drive more smoothly. When luggage needs to be loaded, the first rotating rod and the second rotating rod are rotated, moving the first moving block and the second moving block from close to the roof to above the roof, increasing the volume of luggage, thus framing the luggage, reducing the number of ropes used, facilitating packing, and improving practicality. Depending on the size of the luggage to be packed, the first horizontal bar is pulled away from the end of the mounting block, the second horizontal bar is pulled away from the end of the first moving block, and the third horizontal bar is pulled away from the end of the second moving block, thus increasing the length of the luggage. The first vertical bar is pulled away from the end of the first rotating rod, and the second vertical bar is pulled away from the end of the second rotating rod, thus increasing the height of the luggage. The volume can be changed according to the size of the luggage, thus facilitating the packing of luggage of different sizes, improving flexibility and practicality.

[0006] Preferably, the tops of the first crossbar, the second crossbar, and the third crossbar, as well as the outer sides of the first vertical bar and the second vertical bar, are provided with multiple sets of equally spaced threaded holes. The tops of the mounting block, the first moving block, and the second moving block are each provided with two sets of threaded holes. The outer sides of the first rotating rod and the second rotating rod are each provided with threaded holes.

[0007] Furthermore, a first threaded rod is provided inside the threaded hole, and a first limiting block is fixedly connected to the top of the first threaded rod. The first threaded rod and the threaded hole are designed to be compatible.

[0008] Furthermore, the ends of the two sets of first rotating rods, second rotating rods, and fifth rotating blocks in the same column that are close to each other are all rotatably connected by a connecting rod. A fixed block is rotatably connected to the outside of the connecting rod and located between the two sets of first rotating rods. A connecting block is rotatably connected to the outside of the connecting rod and located between the two sets of second rotating rods and between the two sets of fifth rotating blocks.

[0009] Furthermore, the fixing block on the same side and the two sets of connecting blocks are connected by a second threaded rod, and a second limiting block is fixedly connected to the top of the second threaded rod.

[0010] Furthermore, both the fixing block and the connecting block have threaded holes on their tops, and the threaded holes are designed to be compatible with the second threaded rod.

[0011] Furthermore, elastic bands are fixedly connected to the top of both sets of mounting blocks, and male and female buckles are fixedly connected to the sides of the two sets of elastic bands that are close to each other, with the male and female buckles designed to be compatible.

[0016] This specific embodiment is a detachable car roof rack bracket, the structural diagram of which is shown below. Figure 1-6As shown, the detachable car roof rack bracket includes a main body 1. Two sets of opposing mounting blocks 2 are fixedly connected inside the main body 1. Each of the two sets of mounting blocks 2 has two sets of mounting holes 201 on the side furthest from each other. A first crossbar 202 is slidably connected inside the mounting blocks 2. A first rotating block 203 is fixedly connected to the ends of the two sets of first crossbars 202 within the same set of mounting blocks 2, which are furthest from each other. A first rotating rod 3 is rotatably connected to the side of the two sets of first rotating blocks 203 in the same row, which are closest to each other. A first vertical rod 301 is slidably connected to the end of the first rotating rod 3, which is furthest from the first rotating block 203. A second rotating rod 301 is fixedly connected to the end of the first vertical rod 301, which is furthest from the first rotating rod 3. Block 302, two sets of second rotating blocks 302 in the same column are rotatably connected to each other at their close ends with a third rotating block 402, two sets of third rotating blocks 402 in the same row are fixedly connected to each other at their close ends with a second horizontal bar 401, two sets of second horizontal bars 401 in the same row are slidably connected through a first moving block 4, two sets of third rotating blocks 402 in the same column are rotatably connected to each other at their close ends with a second rotating rod 5, a second vertical bar 501 is slidably connected inside the second rotating rod 5, a fourth rotating block 502 is fixedly connected to the end of the second vertical bar 501 away from the second rotating rod 5, two sets of fourth rotating blocks 502 in the same column are rotatably connected to each other at their close ends with a fifth rotating block 602, two sets of fifth rotating blocks 602 in the same row are rotatably connected to each other at their close ends with a third rotating block 602, two sets of fifth rotating blocks 602 in the same row are rotatably connected to each other at their close ends with a third rotating rod ... Each rotating block 602 has a third crossbar 601 fixedly connected to one end of each other. Two sets of third crossbars 601 in the same row are slidably connected by a second moving block 6. When the detachable car roof rack bracket is in use, the two sets of mounting blocks 2 are installed on the roof of the car through the mounting holes 201 for easy disassembly. When luggage is not needed, the first moving block 4, the second moving block 6, the first rotating rod 3, and the second rotating rod 5 are all flush with the mounting block 2 and in contact with the roof, thereby folding up the main body 1, reducing the volume of the main body 1, reducing wind resistance, and making the car drive more smoothly. When luggage is needed, the first rotating rod 3 and the second rotating rod 5 are rotated to move the first moving block 4 and the second moving block 6 from the roof. The height of the luggage compartment is increased by extending it above the roof of the vehicle, thus confining the luggage, reducing the number of ropes needed, facilitating packing, and improving practicality. Depending on the size of the luggage to be packed, the first horizontal bar 202 is pulled away from the mounting block 2, the second horizontal bar 401 is pulled away from the first moving block 4, and the third horizontal bar 601 is pulled away from the second moving block 6, thereby increasing the length of the luggage compartment. The first vertical bar 301 is pulled away from the first rotating rod 3, and the second vertical bar 501 is pulled away from the second rotating rod 5, thereby increasing the height of the luggage compartment. The volume can be adjusted according to the size of the luggage, making it convenient to pack luggage of different sizes and improving flexibility and practicality.

[0017] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the tops of the first horizontal bar 202, the second horizontal bar 401, and the third horizontal bar 601, as well as the outer sides of the first vertical bar 301 and the second vertical bar 501, are provided with multiple sets of equally spaced threaded holes 702. The tops of the mounting block 2, the first moving block 4, and the second moving block 6 are each provided with two sets of threaded holes 702. The outer sides of the first rotating rod 3 and the second rotating rod 5 are each provided with threaded holes 702. A first threaded rod 701 is provided inside the threaded hole 702. A first limiting block 7 is fixedly connected to the top of the first threaded rod 701. The first threaded rod 701 and the threaded hole 702 are designed to be compatible. When the detachable car roof rack bracket is put into use, the first threaded rod 701 is inserted into the threaded hole 702 through the first limiting block 7, thereby completing the fixation of the mounting block 2 and the first crossbar 202, the first moving block 4 and the second crossbar 401, the second moving block 6 and the third crossbar 601, the first rotating rod 3 and the first vertical rod 301, the second rotating rod 5 and the second vertical rod 501, thus fixing the length and height of the luggage, preventing the first crossbar 202, the second crossbar 401, the third crossbar 601, the first vertical rod 301 and the second vertical rod 501 from sliding and causing the luggage to fall off, thus improving safety.

[0018] Secondly, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the ends of the two sets of first rotating rods 3, second rotating rods 5, and fifth rotating blocks 602 in the same column that are close to each other are rotatably connected by connecting rods 802. A fixing block 8 is rotatably connected to the outside of the connecting rod 802 and between the two sets of first rotating rods 3. Connecting blocks 801 are rotatably connected to the outside of the connecting rod 802 and between the two sets of second rotating rods 5 and the two sets of fifth rotating blocks 602. The fixing block 8 and the two sets of connecting blocks 801 on the same side are connected by a second threaded rod 804. A second limiting block 803 is fixedly connected to the top of the second threaded rod 804. Both the top of the fixed block 8 and the connecting block 801 are provided with threaded holes 702. The threaded holes 702 are designed to be compatible with the second threaded rod 804. When the detachable car roof rack bracket is put into use, the fixed block 8 is fixedly connected to the roof of the car. The connecting rod 802 rotates to facilitate the flattening and erection of the main body 1. When it is necessary to erect the main body 1, the second threaded rod 804 is threaded through the two sets of connecting blocks 801 and then fixed to the fixed block 8 by the second limiting block 803. The other set is installed in sequence to erect and fix the main body 1, preventing the main body 1 from tilting after being erected, thus improving safety.

[0019] Furthermore, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, elastic bands 9 are fixedly connected to the top of both sets of mounting blocks 2. Male buckles 901 and female buckles 902 are fixedly connected to the sides of the two sets of elastic bands 9 that are close to each other. Male buckles 901 and female buckles 902 are designed to be compatible. When the detachable car luggage rack bracket is put into use, when the main body 1 is flat, the elastic bands 9 are covered over the main body 1, and then the male buckles 901 and female buckles 902 are connected. This prevents the main body 1 from standing up due to inertia during riding, thus improving safety. When the main body 1 is standing up, the luggage is placed inside the main body 1. The elastic bands 9 are covered over the luggage, and then the male buckles 901 and female buckles 902 are connected to tie the luggage, which makes it convenient to install the luggage and improves the efficiency of installing and removing the luggage.

[0020] In addition, please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6When using the detachable car roof rack bracket of this technical solution, two sets of mounting blocks 2 are installed on the roof of the car through the mounting holes 201, facilitating overall disassembly. When no luggage is needed, the first moving block 4, the second moving block 6, the first rotating rod 3, and the second rotating rod 5 are all flush with the mounting blocks 2 and close to the roof, thereby folding up the main body 1, reducing its volume, reducing wind resistance, and making the car ride smoother. After the elastic band 9 covers the main body 1, the male buckle 901 and the female buckle 902 are connected, thus preventing the main body 1 from standing up due to inertia during riding, improving safety. When luggage needs to be loaded, the first rotating rod 3 and the second rotating rod 5 are rotated. The two rotating rods 5 move the first moving block 4 and the second moving block 6 from being flush with the roof to being above the roof, increasing the volume of luggage that can be loaded. This helps to frame the luggage, reduce the number of ropes needed, facilitates packing, and improves practicality. Depending on the size of the luggage to be packed, the first horizontal bar 202 is pulled away from the mounting block 2, the second horizontal bar 401 is pulled away from the first moving block 4, and the third horizontal bar 601 is pulled away from the second moving block 6, thereby increasing the length of the luggage that can be loaded. The first vertical bar 301 is pulled away from the first rotating rod 3, and the second vertical bar 501 is pulled away from the second rotating rod 5, thereby increasing the capacity of the luggage that can be loaded. The height can be adjusted to accommodate different sizes of luggage, thus improving flexibility and practicality. The first threaded rod 701 is inserted into the threaded hole 702 via the first limiting block 7, thereby fixing the mounting block 2 and the first horizontal bar 202, the first moving block 4 and the second horizontal bar 401, the second moving block 6 and the third horizontal bar 601, the first rotating rod 3 and the first vertical bar 301, the second rotating rod 5 and the second vertical bar 501. This fixes the length and height of the luggage, preventing the first horizontal bar 202, the second horizontal bar 401, the third horizontal bar 601, the first vertical bar 301 and the second vertical bar 501 from sliding and causing the luggage to fall off. The design improves safety by using a second limiting block 803 to thread the second threaded rod 804 through two sets of connecting blocks 801 and then threading it to the fixing block 8. The other set is then installed sequentially, thus standing the main body 1 upright and securing it, preventing it from tipping over and improving safety. Luggage is placed inside the main body 1, with the elastic band 9 covering it, and the male buckle 901 and female buckle 902 connected to secure it. This facilitates luggage installation and improves the efficiency of luggage installation and removal. Compared with existing detachable car roof rack brackets, this invention improves the overall practicality of the detachable car roof rack bracket through its design.
