A load-bearing off-road vehicle side structure suitable for airdrop and off-road vehicle

Abstract

The invention discloses a side enclosure structure of a load-bearing off-road vehicle suitable for airdrop and an off-road vehicle. The side enclosure structure comprises a side enclosure outer panel, a side enclosure beam assembly, a first supply and suspension unit, a second supply and suspension unit and a door opening reinforcement beam. The side enclosure outer panel is provided with A columns, B columns and C columns which are spaced in sequence. The side enclosure beam assembly is fixed to the side enclosure outer panel to strengthen the structure of the side enclosure outer panel. The first supply and suspension unit and the second supply and suspension unit are both installed on the side enclosure outer panel and are respectively located on one side of the A column and the C column. When the vehicle is airdropped, the vehicle is suspended by the first supply and suspension unit and the second supply and suspension unit, and the pulling force is axially transmitted through the A column and the C column, thereby avoiding deformation of the side enclosure outer panel. Moreover, since the door sealing strip is directly pressed on the side enclosure outer panel, the ultra-high-strength side enclosure outer panel has a strong anti-deformation ability, so that the vehicle can adapt to the stress at the moment of parachute opening and landing, and can also well ensure the sealing of the door.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In order to solve the technical problem in the prior art that the side wall structure of a vehicle is easily deformed and damaged at the moment of parachute opening, an embodiment of the present invention provides a side wall structure of a load-bearing off-road vehicle suitable for airdropping, so as to prevent the vehicle from being deformed at the moment of parachute opening.

[0021] It should be noted that the load-bearing off-road vehicle side enclosure structure suitable for airdrop described in the present invention is used for but not limited to off-road vehicles, etc. For the convenience of explanation, in the present invention, only the application of the side enclosure structure to an off-road vehicle is used as an example for explanation, and the principles of applying the side enclosure structure to other types of equipment are essentially the same as those applied to off-road vehicles, and will not be described in detail here.

[0022] In order to achieve the above technical objectives, the embodiment of the present invention provides a side wall structure of a load-bearing off-road vehicle suitable for airdrop, such as Figure 1-2 As shown, it includes a side outer panel 10, a side outer panel beam assembly 20, a first supply and suspension unit 30, a second supply and suspension unit 40 and a door opening reinforcement beam. The side outer panel 10 is provided with an A pillar 11, a B pillar 12 and a C pillar 13 which are spaced in sequence; the side outer panel beam assembly 20 is fixed to the side outer panel 10; the first supply and suspension unit 30 is installed on the side outer panel 10 and is located on the side of the A pillar 11; the second supply and suspension unit 40 is installed on the side outer panel 10 and is located on the side of the C pillar 13; the door opening reinforcement beam is connected to the side outer panel 10.

[0023] Specifically, the side enclosure structure is provided with a side enclosure outer panel 10, a side enclosure beam assembly 20, a first supply and suspension unit 30, a second supply and suspension unit 40 and a door opening reinforcement beam. The side enclosure outer panel 10 is provided with A pillars 11, B pillars 12 and C pillars 13 spaced in sequence. The side enclosure beam assembly 20 is fixed to the side enclosure outer panel 10 to strengthen the structure of the side enclosure outer panel 10. The first supply and suspension unit 30 and the second supply and suspension unit 40 are both installed on the side enclosure outer panel 10 and are respectively located on the upper sides of the A pillar 11 and the C pillar 13. When the vehicle is provided with the side enclosure structure, the vehicle passes through the first supply and suspension unit 40 during the airdrop operation of the vehicle. The first supply and suspension unit 30 and the second supply and suspension unit 40 are suspended, and the first supply and suspension unit 30 and the second supply and suspension unit 40 will bear the tensile force, and the tensile force will be axially transmitted through the A pillar 11 and the C pillar 13. Through the transmission effect of the A pillar 11 and the C pillar 13, the deformation of the side outer panel 10 can be avoided. The door opening reinforcement beam is connected to the side outer panel 10, which can effectively strengthen the door opening structure, so as not to cause deformation of the door opening, thereby not affecting the sealing of the door, effectively avoiding poor sealing of the door, so that the vehicle can adapt to the force at the moment of opening the parachute and landing, and can also well ensure the sealing of the door.

[0024] In this embodiment, a water retaining groove 50 is provided inside the door opening, and the water retaining groove 50 is welded to the side outer panel, and an installation cavity for installing the door sealing strip is formed between the water retaining groove 50 and the side outer panel 10. The door sealing strip is installed in the installation cavity, one circle of which forms a first sealing structure with the water retaining groove 50, and the other circle is clamped with the side outer panel 10 at the door opening, and squeezes the side outer panel 10 to provide a second sealing structure. The door sealing strip is directly pressed on the side outer panel 10. Since the side outer panel 10 has an ultra-high strength that can prevent deformation during parachute opening and landing, deformation of the water retaining groove 50 can be avoided, ensuring that the door sealing strip can always fit closely with the water retaining groove 50 and the side outer panel 10, thereby ensuring the sealing of the door.

[0025] In this embodiment, the first supply and suspension unit 30 and the second supply and suspension unit 40 are respectively located on the upper sides of the A column 11 and the C column 13 .

[0026] In this embodiment, at the moment of parachute opening, the force on the second suspension unit 40 disposed on the upper side of the C-pillar 13 is relatively large.

[0027] In one embodiment, if Figure 3As shown, a longitudinal structural cavity 131 is formed between the side panel 10 and the C-pillar 13, and the cross-sectional width of the longitudinal structural cavity 131 gradually decreases from the middle part to the two end parts. Specifically, the pulling force of the suspension rope acting on the second suspension unit 40 will form a component force along the direction of the C-pillar 13, prompting the C-pillar 13 to have a tendency to deform in the direction of the suspension rope pulling force. Therefore, the middle part of the C-pillar 13 and the side panel on the C-pillar 13 is an easily deformed part. By forming a longitudinal structural cavity 131 with a cross-sectional width gradually decreasing from the middle part to the two end parts between the side panel 10 and the C-pillar 13, the force is concentrated on the two ends of the C-pillar 13, and the force in the middle part is dispersed, so that the force in the middle part of the C-pillar 13 and the side panel 10 is reduced, which can effectively avoid the deformation of the middle part of the C-pillar 13 and the side panel 10.

[0028] In one embodiment, if Figure 1 As shown, the side panel 10 includes a first connecting section 14 and a second connecting section 15. The lower end of the first connecting section 14 is used to connect to the vehicle floor. The upper end of the first connecting section 14 extends in the vertical direction of the vehicle. The lower end of the second connecting section 15 is fixed to the upper end of the first connecting section 14. The upper end of the second connecting section 15 extends inwardly of the vehicle and is fixed to the vehicle roof. Specifically, when the vehicle falls to the ground, it will be subjected to an upward impact from the ground. The side panel 10 is provided with the first connecting section 14 and the second connecting section 15, and the upper end of the first connecting section 14 extends in the vertical direction of the vehicle, so that the impact direction of the side panel 10 will be the same as that of the first connecting section 14 of the side panel 10, thereby avoiding deformation of the first connecting section 14, and the impact force can be buffered to a certain extent by the first connecting section 14, and finally avoiding deformation of the second connecting section 15, so that the side panel structure will not be deformed by the impact of the ground.

[0029] In one embodiment, if Figure 3 As shown, the longitudinal structural cavity 131 is provided with a reinforcing rib 132, and the two sides of the reinforcing rib 132 are respectively fixedly connected to the C-pillar 13 and the side panel 10. Specifically, the reinforcing rib 132 connects the C-pillar 13 and the side panel 10, so that the C-pillar 13 and the side panel beam can interact with each other, and can strengthen the structure of the C-pillar 13 and the side panel 10, avoid deformation of the C-pillar 13 and the side panel 10, and at the same time, reduce the amount of panel material used and reduce the weight of the side panel structure to achieve lightweighting while ensuring the rigidity and strength of the vehicle body.

[0030] In this embodiment, the reinforcing rib 132 connects the C-pillar 13 and the side outer panel 10 .

[0031] In one embodiment, if Figure 2As shown, the side enclosure beam assembly 20 includes a first transverse reinforcement beam 22, a second transverse reinforcement beam 23 and a third transverse reinforcement beam 24, which are all fixed to the upper side of the side enclosure outer panel 10 and overlap the A pillar 11, the B pillar 12 and the C pillar 13 respectively. Specifically, the first transverse reinforcement beam 22, the second transverse reinforcement beam 23 and the third transverse reinforcement beam 24 can effectively strengthen the strength of the top of the side enclosure outer panel 10 to prevent the top of the side enclosure outer panel 10 from being deformed, and at the same time strengthen the connection between the A pillar 11, the B pillar 12 and the C pillar 13 and the side enclosure outer panel 10 to prevent the side enclosure outer panel 10, the A pillar 11, the B pillar 12 and the C pillar 13 from being deformed.

[0032] In one embodiment, the first transverse reinforcing beam 22, the second transverse reinforcing beam 23 and the third transverse reinforcing beam 24 are provided with a plurality of weight-reducing holes 25. Specifically, the weight-reducing holes 25 can reduce the mass of the first transverse reinforcing beam 22, the second transverse reinforcing beam 23 and the third transverse reinforcing beam 24 while ensuring the structural strength of the first transverse reinforcing beam 22, the second transverse reinforcing beam 23 and the third transverse reinforcing beam 24, thereby reducing the tension on the side enclosure structure and preventing the side enclosure structure from being deformed.

[0033] In this embodiment, the weight-reducing hole 25 is an oblong hole.

[0034] In this embodiment, the side wall beam assembly 20 further includes a side wall reinforcement beam 26, which is arranged along the periphery of the front side door opening and the rear side door opening, and the lower end of the side wall reinforcement beam overlaps the floor. The side wall structure also arranges multiple structures for reinforcing the side wall at the bulletproof side wall outer plate other than the front side door opening and the rear side door opening according to the force transmission path, thereby locally enhancing the strength, rigidity and durability of the bulletproof side wall outer plate.

[0035] In this embodiment, the C-pillar 13 is made of an ultra-high strength thin steel plate material having a thickness similar to that of the side reinforcement beam 26 , so that the vehicle body side can meet the lightweight requirement while ensuring the strength requirement.

[0036] In one embodiment, if Figure 3 As shown, the C-pillar 13 extends along the tension direction of the second supply and suspension unit 40. Specifically, the C-pillar 13 extends along the tension direction of the second supply and suspension unit 40, so that the tension exerted on the second supply and suspension unit 40 will be preferentially transmitted in a straight line along the C-pillar 13, thereby reducing the force acting on the side outer panel 10, and effectively avoiding the deformation of the side outer panel 10.

[0037] Since the second suspension unit 40 on the upper side of the C-pillar 13 is subjected to greater force, the present invention implements a longitudinal structural cavity 131 that gradually decreases from the middle portion to the two end portions, a reinforcing rib 132, a first connecting section 14 extending in the vertical direction of the vehicle, and a C-pillar 13 extending along the tension direction of the second suspension unit 40. This can disperse and transmit the tension on the C-pillar 13, and preferentially transmit the tension in a straight line along the C-pillar 13. While reducing the force on the side outer panel 10, the structure of the easily deformed portion of the side outer panel 10 is effectively strengthened, thereby effectively preventing the side panel structure from being deformed under instantaneous tension and ground impact.

[0038] In one embodiment, if Figure 2 and 4 As shown, the first suspension unit 30 includes a first suspension reinforcement plate 31 and a first suspension point 32. The first suspension reinforcement plate 31 overlaps the first transverse reinforcement beam 22 and the A column 11, and forms a cavity structure between the first transverse reinforcement beam 22 and the A column 11. The first suspension point 32 is arranged on the first suspension reinforcement plate 31. Specifically, the first suspension reinforcement plate 31 can strengthen the strength of the suspension part and reduce the deformation of the suspension part. The first suspension reinforcement plate 31 can reduce the influence of the deformation of the first suspension reinforcement plate 31 on the first transverse reinforcement beam 22 and the A column 11 by forming a cavity structure between the first suspension reinforcement plate 31 and the first transverse reinforcement beam 22 and the A column 11. Since the force of the first suspension unit 30 is smaller than that of the second suspension unit 40, through the above structure, while ensuring the structure of the upper part of the A column, the use of the plate material can be reduced, the weight of the side wall structure can be reduced, and the lightweight of the side wall structure can be achieved.

[0039] In this embodiment, the first hanging point 32 is provided with a hook.

[0040] In one embodiment, if Figure 2 As shown, the second suspension unit 40 includes a second suspension reinforcement plate 41, an inner reinforcement plate 42, a hook reinforcement beam 43 and a second suspension point 44. The second suspension reinforcement plate 41 is connected to the third transverse reinforcement beam 24 and the C-pillar 13, the inner reinforcement plate 42 is fixed to the second suspension reinforcement plate 41, the hook reinforcement beam 43 is fixed to the inner reinforcement plate 42, and the second suspension point 44 is arranged on the second suspension reinforcement plate 41. Specifically, by arranging the second suspension reinforcement plate 41, the inner reinforcement plate 42 and the hook reinforcement beam 43, the strength of the suspension part on the upper side of the C-pillar 13 can be effectively guaranteed, thereby avoiding deformation of the suspension part of the C-pillar 13.

[0041] In this embodiment, the second hanging point 44 is provided with a hook.

[0042] The embodiment of the present invention also provides an off-road vehicle, including a side wall structure. Specifically, the vehicle is provided with the above-mentioned side wall structure, and when the vehicle is airdropped, the off-road vehicle is suspended by the first supply and suspension unit 30 and the second supply and suspension unit 40, and the first supply and suspension unit 30 and the second supply and suspension unit 40 will bear the tensile force, and the tensile force will be axially transmitted through the A column 11 and the C column 13, and the side wall structure is prevented from being deformed through the transmission effect of the A column 11 and the C column 13, and because the door opening reinforcement beam is connected to the side wall outer plate 10, the door opening reinforcement beam will not be deformed, and the sealing of the door will not be affected, effectively avoiding poor sealing of the door, so that the vehicle can adapt to the force at the moment of opening the parachute, and can also well ensure the sealing of the door.

[0043] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
