Description

Technical Field

[0001] This invention relates to the field of vehicle body structural components, and more specifically to a high-strength vehicle body structural component. Background Technology

[0002] As is well known, the vehicle body structure refers to the arrangement of the various components that make up the whole vehicle body and the way the components are assembled. Both civilian vehicles and special-purpose vehicles have certain strength requirements for the vehicle body structure, especially military vehicles. Therefore, in order to achieve safer protection for the occupants, a high-strength vehicle body structure component is proposed.

[0003] A search revealed that Chinese invention patent CN113428088A, published on September 24, 2021, discloses a vehicle body structure and a vehicle having the same. The general description includes an outer body structure with a first chamber and an inner body structure with a second chamber. The inner body structure is disposed within the first chamber, with its outer sidewall separated from the inner sidewall of the first chamber. A top-mounted suspension connects the top of the inner body structure to the top of the outer body structure. In use, when the vehicle encounters a landmine explosion, the top-mounted suspension extends the transmission path of the explosive load, attenuating it. After the landmine explodes, the explosive load passes through the bottom protective components to the bottom plate of the outer body structure, then through the side walls and top of the outer body structure to the top-mounted suspension, and finally through the top-mounted suspension to the top, side walls, and bottom plate of the inner body structure, ultimately reaching the occupants' feet. The extended transmission path of the explosive load significantly reduces its intensity, thus providing safety protection for the occupants.

[0004] While the vehicle body structure described above can provide some lightning protection during use, its bottom protection against landmine explosions is poor, resulting in low practicality. Summary of the Invention

[0031] Example

[0032] Please see Figure 1-8A high-strength vehicle body structure component includes an outer body structure 1, a chassis system, and a mobile body structure. A sunroof is provided at the top of the outer body structure 1 to facilitate entry and exit for occupants. A first bulletproof glass panel 12 and a second bulletproof glass panel 13 are rotatably connected within the sunroof, allowing for opening and closing. A folding frame connects the first bulletproof glass panel 12 and the second bulletproof glass panel 13. Each folding frame includes a first connecting plate 14 and a second connecting plate 15. Both first connecting plates 14 are fixedly connected to the first bulletproof glass panel 12, and both second connecting plates 15 are fixedly connected to the second bulletproof glass panel 13. Both first connecting plates 14 are... A connecting frame 18 is connected via the first connecting shaft 16. Two second connecting plates 15 are each connected to a second connecting shaft 17. The two second connecting shafts 17 are respectively connected to the two connecting frames 18. A lifting protective plate 19 is connected to the bottom end of each of the two connecting frames 18. A vertical sleeve 20 is installed inside the outer vehicle structure 1 for sliding storage and guidance of the lifting protective plate 19. This sleeve works in conjunction with the first bulletproof glass plate 12 and the second bulletproof glass plate 13 to assist in creating a barrier after the first bulletproof glass plate 12 and the second bulletproof glass plate 13 are rotated and opened. The second bulletproof glass plate 13 and the first bulletproof glass plate 12 are respectively connected to an upper closing plate 21 and a lower closing plate 22, which can... After the first bulletproof glass plate 12 and the second bulletproof glass plate 13 are closed relative to each other, the protective barrier at the contact gap between them is provided. Simultaneously, both the upper sealing plate 21 and the lower sealing plate 22 possess a certain degree of deformation toughness, allowing partial deformation during the relative closing process of the first bulletproof glass plate 12 and the second bulletproof glass plate 13. This satisfies the rotation space of the first bulletproof glass plate 12 and the second bulletproof glass plate 13. Furthermore, when the first bulletproof glass plate 12 and the second bulletproof glass plate 13 are completely closed relative to each other, the upper sealing plate 21 and the lower sealing plate 22 will restore their deformation. The first bulletproof glass plate 12 and the second bulletproof glass plate 13 are both fixedly connected to a first sealing plate 23 and a second sealing plate 24. The two first sealing plates 23 are respectively connected to two lifting protective plates. The two second sealing plates 24 are also matched with the two lifting protective plates 19 respectively. After the first bulletproof glass plate 12 and the second bulletproof glass plate 13 are opened relative to each other, the gaps in the area enclosed by the first bulletproof glass plate 12, the second bulletproof glass plate 13 and the two lifting protective plates 19 are sealed. Bulletproof doors 27 are installed at the front and rear ends of the outer body structure 1 and on the rear body 7. Observation windows 28 are provided on the bulletproof doors 27 to facilitate the entry and exit of the occupants and to allow the occupants to observe the outside of the outer body structure 1 after entering the vehicle. An internal combustion engine compartment is set inside the outer body structure 1. After installing an internal combustion engine in the internal combustion engine compartment and adding a transmission gearbox, the power drive for the wheels can be realized.

[0033] It should be further explained that operating levers 25 are fixedly connected to both the first bulletproof glass plate 12 and the second bulletproof glass plate 13. A protective box 2 is fixedly connected to the bottom of the outer vehicle body structure 1, and side boxes 3 are fixedly connected to both the front and rear ends of the protective box 2. Both side boxes 3 are connected to the protective box 2 and fixedly connected to the outer vehicle body structure 1. Multiple openings are provided at the top of each side box 3, and a top plate 4 is installed within each of these openings. Each top plate 4 has an auxiliary opening slot 26 at its top to facilitate rotation and opening. Buffer fluid is provided inside both the protective box 2 and the two side boxes 3. Through the cooperation of the protective box 2 and the side boxes 3, it is easy to form a protective shield for the driver's position at the bottom of the outer vehicle body structure 1. Simultaneously, it facilitates the storage of the buffer solution. In the event of a landmine explosion, it can effectively block and absorb the impact force of the explosion, improving the protection of occupants inside the outer body structure 1. Additionally, if necessary, the bottom of the two side boxes 3 are equipped with drain pipes with on / off valves to facilitate the emptying of the buffer solution after use. Water is the preferred buffer solution, but other suitable buffer solutions can also be selected according to usage requirements. The chassis system includes two longitudinal beams 5, which are fixedly connected by multiple crossbeams 6. Wheels are installed at the bottom of the two longitudinal beams 5. The outer body structure 1 is fixedly connected to the top of the two longitudinal beams 5. The protective box 2 and the two side boxes 3 cooperate to form a semi-enclosed structure, with the longitudinal beams 5 located within the semi-enclosed structure. The mobile body structure includes the rear body 7 and two mobile... Two movable beams 8 are slidably connected within two longitudinal beams 5. Both movable beams 8 are fixedly connected to the bottom end of the rear body panel 7. A connecting shell 9 is fixedly connected to the end of the rear body panel 7 closest to the outer body structure 1. The connecting shell 9 is slidably connected within the outer body structure 1. Through the design of the movable body structure, it can work with the outer body structure 1 to form an adjustable interior space, thus facilitating the increase of body capacity in special circumstances. It is quite flexible in use. A drive structure for adjusting the rear body panel 7 is installed between the two longitudinal beams 5. The drive structure includes a mounting bracket 10 and a tail bracket 11. The mounting bracket 10 is installed between the two longitudinal beams 5, and the tail bracket 11 is installed at the end of the two movable beams 8 away from the outer body structure 1. A hydraulic cylinder is installed on the mounting bracket 10. The telescopic rod of the hydraulic cylinder is fixedly connected to the tail frame 11. The design of the drive structure facilitates the power drive when adjusting the vehicle body structure relative to the outer body structure 1. The interior space adjustment is relatively simple and practical. The outer body structure 1 is equipped with a hydraulic pump matched to the hydraulic cylinder, and the hydraulic pump is equipped with a hydraulic oil tank. The hydraulic pump is connected to the hydraulic cylinder through a pipeline system. The extension and retraction of the hydraulic cylinder can be controlled by controlling the hydraulic pump. Multiple high-intensity lights 29 are installed on the outer body structure 1. Two front wheel arches 30 and two rear wheel arches 31 are installed on the outer body structure 1. The two front wheel arches 30 are fixedly connected to two side boxes 3, and the two rear wheel arches 31 are also fixedly connected to two side boxes 3. Two adjustable wheel arches 32 are fixedly connected to the rear of the vehicle body 7.The two adjustable wheel arches 32 slide against the two rear wheel arches 31 respectively, providing protection for the wheels.

[0034] The hydraulic cylinder, hydraulic pump, wheels, and internal combustion engine in this embodiment are all commercially available conventional equipment known to those skilled in the art. They can also be customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0035] In summary, the working process of this high-strength body structure component is as follows: before use, the top plate 4 is first opened, and then buffer solution is injected into the side box 3 so that the buffer solution can form a certain volume in the side box 3 and the protective box 2. Finally, the top plate 4 is closed. During the process of the occupants entering the outer body structure 1, they can enter by climbing up through the side box 3. During the driving process, when the occupants encounter a landmine explosion on the road they are driving through, the side box 3 and the protective box 2 first bear the impact of the landmine explosion. At the same time, the buffer solution can absorb the impact of the explosion and cool down the parts that bear the explosion. When it is necessary to increase the interior space, the rear body 7 of the vehicle body is moved away from the outer body structure 1 by controlling the operation of the hydraulic cylinder, thereby increasing the interior space formed by the cooperation of the outer body structure 1, the connecting shell 9 and the rear body 7.
