Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to lightweight automotive monocoque bodies and body panels. Background Technology

[0002] The vehicle body refers to the part of a vehicle used for carrying people and goods, and also refers to the vehicle as a whole. Some vehicles have a body that serves as both the driver's workplace and a place to accommodate passengers and cargo. The body's styling and structure are the vehicle's physical language, and its design directly affects the vehicle's performance. The roof is one part of the vehicle's body covering. To facilitate the carrying of large items, these items are secured to the top of the vehicle's roof using luggage racks.

[0003] However, due to the different dimensions of each car, when the size of the roof rack is larger than the spacing between the roof rails on the car's hood, the roof rack is located outside the roof rails on both sides, making it impossible to install the roof rack on the car's hood. When the size of the roof rack is smaller than the size of the roof rails on the car's hood, the roof rack is located between the roof rails on both sides, resulting in a certain gap between the roof rack and the roof rails. This also prevents the roof rack from being installed on the roof rails on the car's hood. In this case, the use of the roof rack needs to correspond to the spacing between the roof rails on the car's hood, which limits the applicability of the roof rack and affects its flexibility in actual use.

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.

[0022] Please see Figure 1 and Figure 3The lightweight vehicle body and roof assembly include a body body and a roof body 1. The roof body 1 is mounted on top of the body body. Top rods 2 are fixedly mounted on the front and rear sides of the upper surface of the roof body 1, connecting the roof body 1 to the roof rack. A sleeve rod 3 is movably mounted between the front and rear top rods 2. A threaded rod 4 is threaded onto the inner wall of the sleeve rod 3. This threaded connection allows the threaded rod 4 to rotate circumferentially while also achieving linear movement. A turntable 5 is fixedly mounted at the rear end of the threaded rod 4. The support rod 6 connects the threaded rod 4 and the support rod 6. The front end of the sleeve rod 3 and the rear end of the turntable 5 are respectively provided with support rods 6 located inside the top rod 2. The upper end of the support rod 6 is fixedly installed with a lower mounting plate 7 located below the top rod 2. One end of the lower mounting plate 7 is movably connected to an upper mounting plate 8 located above the top rod 2. Extension plates 9 are fixedly installed on the outer sides of the upper mounting plate 8 and the lower mounting plate 7 respectively. The inner wall of the extension plate 9 is threaded with fastening bolts 10. The fastening bolts 10 are provided to connect the upper and lower extension plates 9, so that the upper mounting plate 8 and the lower mounting plate 7 are fixed on the top rod 2.

[0023] A reinforcing plate 11 is provided on the left and right sides of the top surface of the inner wall of the vehicle roof body 1. A gasket 12 is fixedly installed on the upper end of the reinforcing plate 11. The gasket 12 is used to connect the vehicle roof body 1 and the reinforcing plate 11. A movable rod 13 is movably connected to the side of the reinforcing plate 11 away from the gasket 12. The movable rod 13 is used to connect the reinforcing plate 11 and the damping block 14. The lower end of the movable rod 13 is movably connected to the damping block 14. A positioning rod 15 is movably sleeved on the inner wall of the damping block 14. The left and right ends of the positioning rod 15 are fixedly connected to the left and right sides of the inner wall of the vehicle roof body 1, respectively. A spring 16 is fixedly installed on the outer side of the damping block 14, located outside the positioning rod 15. The end of the spring 16 away from the damping block 14 is fixedly connected to the inner wall of the vehicle roof body 1. The spring 16 is used to connect the damping block 14 and the vehicle roof body 1.

[0024] Please see Figure 2 and Figure 6 A rotating rod 17 is fixedly installed on the inner end of the lower mounting plate 7. A bracket 18 is movably connected to the end of the rotating rod 17 away from the lower mounting plate 7. The upper end of the bracket 18 is fixedly connected to the upper mounting plate 8. The rotation of the rotating rod 17 allows the upper mounting plate 8 to rotate on the lower mounting plate 7, thereby facilitating the installation or removal of the upper mounting plate 8 and the lower mounting plate 7 on the top rod 2.

[0025] Annular blocks 21 are fixedly fitted onto the sleeve rods 3 and threaded rods 4 on the left and right sides respectively. The annular blocks 21 on the left and right sides are connected by a horizontal tube 19 and a round rod 20. The movement of the round rod 20 inside the horizontal tube 19 facilitates the adjustment of the distance between the annular blocks 21 on the left and right sides. The left end of the horizontal tube 19 is connected to the annular block 21 on the left side, and the right end of the round rod 20 is connected to the annular block 21 on the right side. The inner wall of the horizontal tube 19 is movably fitted onto the outer wall of the round rod 20.

[0026] Please see Figure 4 and Figure 5 A second rotating rod 22 is fixedly installed at the lower end of the reinforcing plate 11. A second bracket 23 is connected to the side of the second rotating rod 22 away from the reinforcing plate 11. The second bracket 23 is set to connect the side plate 24 and the second rotating rod 22. A side plate 24 is fixedly installed at the lower end of the second bracket 23, and the side of the side plate 24 away from the second bracket 23 is fixedly connected to the upper end of the movable rod 13. The side plate 24 is set to connect the second bracket 23 and the movable rod 13.

[0027] A third bracket 26 is fixedly installed on the upper end face of the damping block 14. A collar 25 is movably connected to the end of the third bracket 26 away from the damping block 14. The outer wall of the collar 25 is fixedly connected to the lower end of the movable rod 13. The collar 25 is set to connect the movable rod 13 and the third bracket 26.

[0028] Working principle: In use, firstly, fix the lower mounting plate 7 and upper mounting plate 8 on the left side to the left end of the front top rod 2. Install the lower mounting plate 7 below the top rod 2. By rotating the first bracket 18 on the first rotating rod 17, the upper mounting plate 8 is fixed above the top rod 2. Then, use the fastening bolts 10 to connect the extension plates 9 on the upper mounting plate 8 and lower mounting plate 7, thus fixing the lower mounting plate 7 and upper mounting plate 8 to the top rod 2. Due to the movable connection between the horizontal tube 19 and the round rod 20, the distance between the lower mounting plate 7 and upper mounting plate 8 on the left and right sides can be adjusted. Following the above steps, install the lower mounting plate 7 and upper mounting plate 8 on the right side of the front top rod 2. Then, due to the threaded connection between the sleeve rod 3 and the threaded rod 4... This allows the threaded rod 4 to rotate circumferentially while also achieving linear motion. As the threaded rod 4 moves, it drives the lower mounting plate 7 and upper mounting plate 8 on the rear side to be mounted on the top rod 2 via the turntable 5. At this time, the lower mounting plate 7 and upper mounting plate 8 in four directions are fixed to the left and right ends of the top rod 2 on the front and rear sides, respectively, so that the roof rack can be adjusted according to the size of the car itself. Finally, when the roof body 1 is impacted by an external force, the roof body 1 deforms and contacts the pad 12, driving the movement of the reinforcing plate 11. By utilizing the movement of the damping block 14 on the positioning rod 15, and in conjunction with the elasticity of the spring 16, the reinforcing plate 11 provides support for the roof body 1, while also preventing injury to passengers after the roof body 1 is damaged in an impact.
