Description

Technical Field

[0001] This utility model relates to the field of lightweight vehicle body manufacturing technology, and in particular to a lightweight aluminum alloy vehicle body. Background Technology

[0002] Lightweight aluminum alloy truck bodies are truck bodies made with aluminum alloy as the core material and through optimized structural design. The core feature is that while ensuring structural strength and load-bearing capacity, the weight is significantly reduced. At the same time, they are corrosion-resistant and easy to maintain. In order to reduce the weight of the vehicle body, fuel consumption or energy consumption can be reduced, the effective load can be increased, and transportation efficiency can be improved. Moreover, the lightweight design does not sacrifice structural stability, which can ensure the safety of cargo transportation. It also meets the industry's demand for energy conservation and emission reduction. Therefore, there is a need for a lightweight aluminum alloy truck body. In the past, the carriages generally had problems such as excessive weight and unreasonable structural reinforcement methods. Due to the heavy materials or bulky reinforcement structure, the transportation energy consumption was high and the effective load was limited. Insufficient support design resulted in poor structural stability, which in turn affected the safety of use. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a lightweight aluminum alloy carriage, which aims to improve the problems of high transportation energy consumption and limited effective load due to heavy materials or bulky reinforced structures, and poor structural stability due to insufficient support design.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lightweight aluminum alloy carriage, comprising a top plate, side plates, a back plate, and a bottom plate. The outer wall of the top plate is fixedly connected to the outer walls of the side plates and the back plate. The outer walls of the side plates are respectively fixedly connected to the outer walls of the back plate and the bottom plate. The outer wall of the back plate is fixedly connected to the outer wall of the bottom plate. A top reinforcing rib is fixedly connected to the outer wall of the top plate. Reinforcing grooves are provided inside the side plates and the back plate. Columns are fixedly connected to the outer walls of the top plate, side plates, back plate, and bottom plate. Door frames are fixedly connected to the outer walls of the columns. Hinges are fixedly connected to the interior of the door frames. A carriage door is fixedly connected to the outer wall of the hinges. A door lock is fixedly connected to the outer wall of the carriage door. A locking assembly is provided on the outer wall of the bottom plate.

[0005] Preferably, the engaging assembly includes a vertical reinforcing plate and a horizontal reinforcing plate. The outer wall of the vertical reinforcing plate is disposed on the outer wall of the base plate. Both the vertical and horizontal reinforcing plates have slots inside, and the vertical and horizontal reinforcing plates engage with each other.

[0006] Preferably, the outer walls of both the vertical and horizontal reinforcing plates are provided with L-shaped plates, and bolts are provided inside the vertical, horizontal, and L-shaped plates.

[0007] Preferably, the outer wall of the bolt is provided with anti-slip pad one and anti-slip pad two, the outer wall of the anti-slip pad one is in contact with the outer wall of the L-shaped plate, and the outer wall of the anti-slip pad two is fixedly connected with a nut.

[0008] Preferably, the outer wall of the bolt is fixedly connected to a screw and a threaded rod, and the outer wall of the threaded rod is disposed inside the screw.

[0009] Preferably, the nut is internally threaded to the outer wall of both the bolt and the screw.

[0010] Preferably, the outer wall of the threaded rod is threadedly connected to a threaded cylinder, and the outer wall of the threaded cylinder is fixedly connected to a tapered cylinder.

[0011] Preferably, the outer wall of the conical cylinder is fixedly connected to two bolts, and the outer wall of the conical cylinder is slidably connected to the inner wall of the screw.

[0012] This utility model has the following beneficial effects: 1. In this utility model, a closed loading space is constructed based on the mutual fixing of the top plate, side plate, back plate and bottom plate. The top reinforcing rib, reinforcing groove, column and locking assembly reinforce the car body structure from the top, side, back and bottom respectively. With the support design of the reinforcing groove, the overall weight is reduced while the structural strength is improved. The door frame, hinge, car door and door lock form an opening and closing control system. The door can be opened and closed flexibly by the rotation of the hinge and then fixed in the closed state by the door lock. It meets the requirements of lightweight use and achieves the effect of ensuring the load-bearing capacity and structural stability of the car body and improving the safety of use.

[0013] 2. In this utility model, an L-shaped plate is placed at the connection between the horizontal and vertical reinforcing plates. Bolts, screws, and threaded rods are passed through the horizontal reinforcing plate and the L-shaped plate. Anti-slip pad one is then inserted into the bolt, ensuring its smooth surface adheres to the outer wall of the L-shaped plate. Tightening the nut causes it to move, bringing anti-slip pad two into contact with and pressing against the rough surface of anti-slip pad one. The nut is then tightened further, increasing friction to prevent the nut from shaking. Subsequently, a conical cylinder is inserted into the screw. Rotating bolt two allows the threaded cylinder to move along the outer wall of the threaded rod, causing the conical cylinder to slide along the inner wall of the screw. The conical cylinder causes the screw to expand outward, pressing against the inner wall of the nut, tightening bolt two to secure the nut. This prevents the nut from falling off, ensuring the reinforcing plate connection structure remains stable and reliable even under long-term driving vibrations in the lightweight aluminum alloy car body, thus extending the car body's service life.

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: a lightweight aluminum alloy carriage, including a top plate 1, side plates 2, back plate 3 and bottom plate 4. The outer wall of the top plate 1 is fixedly connected to the outer walls of the side plates 2 and the back plate 3. The outer walls of the side plates 2 are respectively fixedly connected to the outer walls of the back plate 3 and the bottom plate 4. The outer wall of the back plate 3 is fixedly connected to the outer wall of the bottom plate 4. A top reinforcing rib 5 is fixedly connected to the outer wall of the top plate 1. Reinforcing grooves 6 are provided inside the side plates 2 and the back plate 3. Columns 7 are fixedly connected to the outer walls of the top plate 1, side plates 2, back plate 3 and bottom plate 4. A door frame 8 is fixedly connected to the outer wall of the column 7. A hinge 9 is fixedly connected inside the door frame 8. A door 10 is fixedly connected to the outer wall of the hinge 9. A door lock 11 is fixedly connected to the outer wall of the door 10. A locking assembly is provided on the outer wall of the bottom plate 4. Specifically, the multi-faceted connection method, where the side panels 2 and back panels 3 are fixed to the outer wall of the top plate 1, the back panels 3 and bottom plates 4 are fixed to the side panels 2 respectively, and the bottom plates 4 are fixed to the back panels 3, effectively forms a closed loading space and achieves the effect of constructing the basic structure of the carriage. The top reinforcing ribs 5 on the outer wall of the top plate 1 increase the structural thickness, thus dispersing the stress on the top of the carriage and preventing deformation of the top plate 1 under stress. This also prevents water or snow accumulation in the reinforcing grooves 6 of the top plate 1 during rain or snow. The hollow structure reserved in the reinforcing grooves 6 inside the side panels 2 and back panels 3 reduces their weight while improving their bending resistance, achieving a balance between lightweighting and structural stability. The structure features multiple supports at the joints of the top plate 1, side plate 2, back plate 3, and bottom plate 4 via columns 7, which strengthen the overall rigidity of the carriage frame and prevent loosening or deformation at the joints. The door frame 8 on the outer wall of the columns 7 provides an installation reference, which in turn drives and fixes the hinges 9 and the door 10, ensuring proper assembly of the door 10. The hinges 9 inside the door frame 8 utilize hinge transmission to allow the door 10 to rotate flexibly around the frame, facilitating easy opening and closing. The door lock 11 on the outer wall of the door 10 locks the connection between the door 10 and the door frame 8, securing the door 10 in a closed state and ensuring the safety of items inside the carriage.

[0018] Reference Figure 3 and Figure 4 The engaging assembly includes a vertical reinforcing plate 13 and a horizontal reinforcing plate 12. The outer wall of the vertical reinforcing plate 13 is disposed on the outer wall of the base plate 4. The interior of both the vertical reinforcing plate 13 and the horizontal reinforcing plate 12 is provided with a slot 14, and the vertical reinforcing plate 13 and the horizontal reinforcing plate 12 engage with each other. Specifically, the interlocking grooves 14 inside the vertical reinforcing plate 13 and the horizontal reinforcing plate 12 in the outer wall interlocking assembly of the base plate 4 play a role in forming a cross-support structure, thereby enhancing the load-bearing capacity of the base plate 4.

[0019] Reference Figure 4 , Figure 6 and Figure 7 The outer walls of the vertical reinforcing plate 13 and the horizontal reinforcing plate 12 are each provided with an L-shaped plate 15. Bolt 16 is provided inside the vertical reinforcing plate 13, the horizontal reinforcing plate 12 and the L-shaped plate 15. Anti-slip pad 17 and anti-slip pad 28 are respectively provided on the outer walls of bolt 16. The outer wall of anti-slip pad 17 fits against the outer wall of the L-shaped plate 15. Nut 19 is fixedly connected to the outer wall of anti-slip pad 28. Screw 20 and threaded rod 21 are respectively fixedly connected to the outer walls of bolt 16. The outer wall of threaded rod 21 is located inside the screw 20. Specifically, the L-shaped plate 15 is attached to the connection between the horizontal reinforcing plate 12 and the vertical reinforcing plate 13. Bolt 16, screw 20, and threaded rod 21 pass through these three components, precisely positioning and connecting the horizontal and vertical reinforcing plates 12 and 13. This provides a stable connection point for the car body reinforcement structure, ensuring the connection accuracy and overall rigidity of the aluminum alloy car body frame. Anti-slip pad 17 is inserted into bolt 16, with its smooth surface adhering to the outer wall of the L-shaped plate 15. Tightening nut 19 moves anti-slip pad 18 towards anti-slip pad 17. The rough surfaces of the two pads press against each other, increasing the friction and preventing the nut 19 from loosening due to vibration. This prevents the nut 19 from shifting during vehicle movement due to bumps.

[0020] Reference Figure 5 , Figure 6 and Figure 7 The nut 19 is threaded to the outer wall of the bolt 16 and the screw 20 respectively; the outer wall of the threaded rod 21 is threaded to the threaded cylinder 22, and the outer wall of the threaded cylinder 22 is fixedly connected to the tapered cylinder 23; the outer wall of the tapered cylinder 23 is fixedly connected to the bolt 24, and the outer wall of the tapered cylinder 23 is slidably connected to the inner wall of the screw 20. Specifically, the conical cylinder 23 is inserted into the screw 20, and the bolt 24 is rotated to drive the threaded cylinder 22 to rotate and move on the outer wall of the threaded rod 21. This causes the conical cylinder 23 to slide along the inner wall of the screw 20. The conical structure of the conical cylinder 23 continuously squeezes the inner wall of the screw 20, which in turn causes the screw 20 to expand outward. This allows the screw 20 to tightly squeeze the inner wall of the nut 19 to form a secondary fastening, achieving the effect of double locking of the nut 19 and completely preventing it from falling off. This ensures that the reinforced plate connection structure of the lightweight aluminum alloy car body remains stable and reliable under long-term driving vibration, thus extending the service life of the car body.

[0021] Working principle: When using this carriage, a closed loading space is constructed based on the mutual fixation of the top plate 1, side plate 2, back plate 3 and bottom plate 4. The top reinforcing rib 5, reinforcing groove 6, column 7 and locking assembly reinforce the carriage structure from the top, side, back and bottom respectively. The support design of the reinforcing groove 6 reduces the overall weight while improving the structural strength. The door frame 8, hinge 9, carriage door 10 and door lock 11 form an opening and closing control system. The flexible opening and closing of the carriage door 10 is achieved by the rotation of the hinge 9, and the door lock 11 fixes the closed state. The cooperation of each mechanism meets the requirements of lightweight use and achieves the effect of ensuring the load-bearing capacity, structural stability and safety of use of the carriage. Then, place the L-shaped plate 15 at the connection between the horizontal reinforcing plate 12 and the vertical reinforcing plate 13. Pass the bolt 16, screw 20, and threaded rod 21 through the horizontal reinforcing plate 12 and the L-shaped plate 15. Then, insert the anti-slip pad 17 into the bolt 16, ensuring its smooth side is against the outer wall of the L-shaped plate 15. Next, tighten the nut 19, causing it to move against the outer wall of the bolt 16, thereby bringing the anti-slip pad 18 into contact with and pressing against the rough surface of the anti-slip pad 17. Continue tightening the nut 19 until it is fully tightened, thereby increasing the anti-slip effect. The friction between the sliding pad 17 and the anti-slip pad 18 prevents the nut 19 from shaking. Then, the conical cylinder 23 is inserted into the screw 20, and the bolt 24 is rotated to move the threaded cylinder 22 on the outer wall of the threaded rod 21. This causes the conical cylinder 23 to move on the inner wall of the screw 20. The conical cylinder 23 causes the screw 20 to expand outward, which in turn causes the screw 20 to press against the inner wall of the nut 19. By tightening the bolt 24, the nut 19 is fixed, thus preventing it from falling off.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
