[0002] The main components of a car body are metallic materials, such as steel plates, carbon fiber, aluminum, and reinforced plastics. Different materials are used for car bodies of different purposes. The body mainly relies on the uniform distribution of mid-surface stress along its thickness to achieve greater load-bearing capacity. The fuel tank shell is also a type of car body. Currently, car fuel tank shells do not have quick disassembly and assembly functions. When installing a car fuel tank shell, the complex and cumbersome installation process causes operators to waste a lot of time and energy. Moreover, it does not have protective functions. When a car is involved in a collision, the fuel tank shell is easily deformed or damaged, leading to damage to the fuel tank. Therefore, there is a need for a car body shell that has protective functions and is easy to disassemble and assemble. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a car body with protective function, which solves the problem that the car fuel tank shell is not quick to install and remove. When installing the car fuel tank shell, the complicated and cumbersome installation process causes operators to waste a lot of time and energy. Moreover, it does not have a protective function. When the car is hit by a collision, the car fuel tank shell is easily deformed or damaged, which leads to damage to the fuel tank.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a car body with protective function, comprising an outer shell, a cover plate on the outer shell, two handles fixedly connected to the cover plate, four connecting rods through and snapped onto the cover plate, a rotating arm fixedly connected to the top of each connecting rod, a locking post through and snapped onto the rotating arm, four slots on the cover plate, the inner wall of each slot slidingly engaging with the locking post, a slider fixedly connected to the bottom end of each connecting rod, four first sliding grooves on the outer shell, the inner wall of each first sliding groove slidingly engaging with the slider, a second sliding groove on the inner wall of each first sliding groove slidingly engaging with the outer side of the slider, a base plate on the bottom side of the slider, the outer side of the base plate slidingly engaging with the inner wall of each first sliding groove, a first spring installed on the bottom side of the base plate, the bottom end of the first spring fixedly connected to the outer shell, and a torsion spring sleeved on the outer side of each connecting rod.

[0005] As a further embodiment of this utility model: a support plate is slidably engaged with the inner wall of the outer shell, and four second springs are installed on the bottom side of the support plate, with the bottom ends of the second springs fixedly connected to the inner wall of the outer shell.

[0006] As a further embodiment of this utility model: a damping block is provided on the bottom side of the support plate, and the damping block is fixedly connected to the inner wall of the outer shell.

[0007] As a further embodiment of this utility model: four third springs are fixedly connected to both sides of the outer shell, an air cushion is installed at one end of each third spring, two air pipes are fixedly connected to both sides of the air cushion, an inflation box is installed at one end of each air pipe, the inflation box is fixedly connected to the outer shell, and an air valve is installed on one side of the inflation box.

[0008] As a further embodiment of this utility model: four telescopic rods are installed on one side of the air cushion, and one end of each telescopic rod is fixedly connected to the outer shell.

[0009] As a further embodiment of this utility model: mounting plates are fixedly connected to both sides of the outer shell, and nuts are threaded onto the mounting plates.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This protective car body, comprising an outer shell, cover plate, rotating arm, locking pin, locking groove, slider, first sliding groove, second sliding groove, base plate, first spring, torsion spring, and connecting rod, allows for quick installation of the fuel tank after the fuel tank is placed inside the outer shell. The operator first rotates the rotating arm, causing the torsion spring to deform. The rotating arm then rotates the locking pin to the appropriate position, pushing it into the locking groove for engagement. The cover plate is then aligned with the outer shell and installed. The connecting rod drives the slider to slide within the first sliding groove, which in turn moves the base plate and retracts the first spring. Once the slider reaches the appropriate position, the operator pulls out the locking pin, causing the torsion spring to return to its original position and rotate the rotating arm and locking pin. The rotating arm then rotates the connecting rod, which in turn drives the slider to slide within the second sliding groove. This allows for rapid installation of the fuel tank, preventing overly complex and cumbersome installation processes that would otherwise waste the operator's time and effort, thus improving the ease of use of the car body.

[0012] 2. This protective car body, by incorporating a third spring, air cushion, telescopic rod, air hose, inflation box, and air valve, allows the operator to operate the air valve before use. This allows the inflation box to draw in outside air, which is then delivered into the air cushion via the air hose. When the car is involved in a collision, the external force causes the air cushion to move towards the outer shell and the third spring to contract, thereby absorbing the external force and protecting the outer shell and the fuel tank inside. This prevents damage to the fuel tank from external forces and enhances the protective performance of the car body. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-6 As shown, this utility model provides a technical solution: a car body with protective function, including an outer shell 1, a support plate 13 slidably snapped onto the inner wall of the outer shell 1, and four second springs 14 installed on the bottom side of the support plate 13. The bottom end of the second springs 14 is fixedly connected to the inner wall of the outer shell 1. Because of the second springs 14, when the car body is vibrated, the fuel tank presses down on the support plate 13, the support plate 13 moves down and causes the second springs 14 to contract. When the second springs 14 return to their original position, they push the support plate 13 and the fuel tank up, thereby effectively absorbing the vibration, preventing the vibration from damaging the fuel tank, and improving the protective performance of the outer shell 1.

[0022] A damping block 15 is provided on the bottom side of the support plate 13. The damping block 15 is fixedly connected to the inner wall of the outer shell 1. Because of the damping block 15, when the support plate 13 moves downward under the influence of vibration, the damping block 15 deforms, thereby buffering the support plate 13 and preventing insufficient elasticity of the second spring 14, which would result in the vibration not being completely absorbed, thus improving the functionality of the shell. A cover plate 2 is provided on the outer shell 1. Two handles 24 are fixedly connected to the cover plate 2. Four connecting rods 12 are inserted and snapped through the cover plate 2. A rotating arm 3 is fixedly connected to the top of the connecting rod 12. The cover plate 2 has four slots 5, and the inner wall of the slots 5 is slidably engaged with the slots 4. The bottom end of the connecting rod 12 is fixedly connected to the slider 6. The outer shell 1 has four first sliding grooves 7, and the inner wall of the first sliding grooves 7 is slidably engaged with the slider 6. The outer shell 1 has four third springs 16 fixedly connected to both sides. One end of the third spring 16 is equipped with an air cushion 17. Two air pipes 19 are fixedly connected to both sides of the air cushion 17. One end of the air pipe 19 is equipped with an air box 20. The air box 20 is fixedly connected to the outer shell 1. An air valve 21 is installed on one side of the air box 20.

[0023] Four telescopic rods 18 are installed on one side of the air cushion 17. One end of each telescopic rod 18 is fixedly connected to the outer shell 1. Because of the telescopic rods 18, when the air cushion 17 moves, the telescopic rods 18 extend or retract along with the air cushion 17, thereby limiting the movement of the air cushion 17 while ensuring its normal movement and preventing it from shifting during movement, which would reduce the protection of the outer shell 1 and improve the stability of the air cushion 17 during movement. A second slide groove 8 is provided on the inner wall of the first slide groove 7. The inner wall of the second slide groove 8 is slidably engaged with the outer side of the slider 6. A base plate 9 is provided on the bottom side of the slider 6. The outer side of the base plate 9 is engaged with the outer side of the slider 6. The inner wall of the first slide groove 7 is slidably engaged. A first spring 10 is installed on the bottom side of the base plate 9. The bottom end of the first spring 10 is fixedly connected to the outer shell 1. A torsion spring 11 is sleeved on the outer side of the connecting rod 12. Mounting plates 22 are fixedly connected to both sides of the outer shell 1. Nuts 23 are threadedly engaged on the mounting plates 22. Because of the mounting plates 22, when fixing and installing the shell, the operator places the mounting plates 22 in the area to be installed, and then rotates the nuts 23 on the mounting plates 22 until the nuts 23 are fully engaged with the area to be installed. This prevents the waste of extra manpower and resources during fixing and installation, and improves the ease of use of the shell.

[0024] The working principle of this utility model is as follows: When fixing and installing the housing, the operator places the mounting plate 22 in the area to be installed, and then rotates the nut 23 on the mounting plate 22 until the nut 23 is fully engaged with the area to be installed. Before using the housing, the operator rotates the air valve 21 to allow the air box 20 to draw in outside air and send the air into the air cushion 17 through the air pipe 19. When the car is hit by a collision, the external force causes the air cushion 17 to move towards the outer shell 1 and causes the third spring 16 to contract, thereby absorbing the external force. After the fuel tank is placed inside the outer shell 1, the operator first rotates the rotating arm 3 and causes the torsion spring 11 to deform. The rotating arm 3 drives the locking pin 4 to rotate to the appropriate position, and then the locking pin 4 is engaged. Push the cover plate 2 into the slot 5 and install it. Then, align the cover plate 2 with the outer shell 1. The connecting rod 12 drives the slider 6 to slide in the first slide groove 7. The slider 6 pushes the base plate 9 to move and causes the first spring 10 to retract. After the slider 6 moves to the appropriate position, the operator pulls out the locking pin 4. The torsion spring 11 returns to its original position and drives the rotating arm 3 and the locking pin 4 to rotate. The rotating arm 3 drives the connecting rod 12 to rotate. The connecting rod 12 drives the slider 6 to slide in the second slide groove 8, thereby quickly installing the oil tank. When the shell is vibrated, the oil tank presses down on the support plate 13. When the support plate 13 moves down, it causes the second spring 14 to retract and the damping block 15 to deform. When the second spring 14 returns to its original position, it pushes the support plate 13 and the oil tank to move up.
