[0006] The purpose of this utility model is to provide a prefabricated automotive chassis protection structure to solve the problem mentioned in the background art. Currently, the entire structure can be supported by four positioning cylinders and four L-shaped support seats, which has better stability and practicality. However, in actual use, the engine oil needs to be changed regularly during normal use of the car. When changing the engine oil, the drain plug at the bottom of the oil pan is usually unscrewed to drain the oil. Although the protective plate can protect the bottom of the engine, it is inconvenient to repeatedly remove and install the protective plate when changing the engine oil regularly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an assembled automobile chassis protective structure, including a protective plate;

[0008] The top of the protective plate has two sets of mounting holes symmetrically connected through it;

[0009] Also includes:

[0010] Movable components are provided inside and at the bottom of the protective plate;

[0011] The movable component includes support frames symmetrically installed inside the bottom of the protective plate, and support plates symmetrically installed between the two support frames. A movable frame is slidably connected to the outside of the two support plates, and a baffle is fixedly installed at the bottom of the movable frame.

[0012] The protective plate has a rectangular groove extending through it above the baffle. A positioning frame is fixedly installed on one side of the bottom of the baffle. A positioning rod is symmetrically slidably connected inside the positioning frame. A torsion spring is sleeved on one side of the positioning rod, and one end of the torsion spring is fixedly connected to the positioning frame. A magnet is fixedly installed on one side of the support frame near the movable frame.

[0013] Preferably, a handle is fixedly installed at one end of each of the two positioning rods, and the other end of the torsion spring is fixedly connected to the handle. A fixing block is symmetrically installed on one side of the bottom of the protective plate located on the baffle. A connecting groove is opened through one side of each of the two fixing blocks, and the positioning rod is inserted into the connecting groove.

[0014] Preferably, the connecting groove has symmetrically formed limiting grooves on both sides inside, and the positioning rod is symmetrically installed with limiting blocks on one side of the fixing block, and one side of the limiting block abuts against the fixing block.

[0015] Preferably, a limiting frame is symmetrically installed on one side of the positioning frame between the two positioning rods, and a moving rod is slidably connected inside the two limiting frames.

[0018] Preferably, a knurled screw is provided on one side of the inside of the knob, and a plurality of threaded holes are provided circumferentially on the side of the mounting bracket away from the positioning bracket, and the knurled screw is threadedly connected to the threaded holes.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This assembled automobile chassis protection structure allows the automobile chassis to be protected by a protective plate. When the engine oil needs to be changed, the drain plug at the bottom of the engine oil pan is easily exposed, eliminating the need to repeatedly disassemble and reassemble the protective plate when changing the engine oil regularly, thus improving the convenience of use. The specific details are as follows:

[0020] 1. The protective plate is installed on the car chassis through mounting holes. The baffle is located below the engine oil pan. When changing the engine oil, the handle can be grasped and rotated to rotate the positioning rod 90 degrees. After the positioning rod rotates, the limiting block aligns with the limiting groove. At the same time, the rotation of the positioning rod causes the torsion spring to deform, allowing the baffle to move and the limiting block to retract from the limiting groove. After the baffle moves, it causes the movable bracket to slide on the support plate. After the baffle moves, the movable bracket contacts the magnet on one side of the support bracket. The movable bracket is made of metal and can be attracted to the magnet. The baffle no longer obstructs the rectangular groove, allowing the engine oil pan to leak out. To facilitate oil changes, the baffle is reset, the movable bracket disengages from the magnet, and the handle is turned to rotate the positioning rod, aligning the limit block with the limit groove. As the baffle moves, the limit block passes through the limit groove. Then, the handle is released, and the positioning rod is reset and rotated under the action of the torsion spring, causing the limit block to be misaligned with the limit groove, thus positioning the baffle. At this time, the movable bracket is in contact with the support bracket on the other side, allowing the car chassis to be protected through the protective plate. When the engine oil needs to be changed, the drain plug at the bottom of the engine oil pan is easily exposed, eliminating the need to repeatedly disassemble and reassemble the protective plate when changing the engine oil regularly, thus improving the convenience of use.

[0021] 2. Before turning the handle, turn the knurled screw to disengage it from the threaded hole, causing the knob to lose its limit position. Turning the knob then rotates the screw, which in turn moves the movable block, causing the connecting rod to rotate and push the moving rod. This causes the moving rod to bring the two limit plates closer together, allowing the handle to lose its limit position. After the baffle returns to its original position, the knob can be turned in the opposite direction to bring the two limit plates into contact with the handle. Then, the knurled screw is passed through the knob and screwed into the threaded hole to position the screw, which in turn positions the handle. This prevents the handle from easily turning while the car is in motion, avoids accidental movement of the baffle, and improves practicality. Attached Figure Description

A positioning frame 206 is fixedly installed on one side of the bottom of 205, and a positioning rod 207 is symmetrically slidably connected inside the positioning frame 206. A torsion spring 208 is sleeved on the outer side of the positioning rod 207, and one end of the torsion spring 208 is fixedly connected to the positioning frame 206. A magnet block 2011 is fixedly installed on one side of the support frame 201 near the movable frame 203, so that the chassis of the car can be protected by the protective plate 1. When the engine oil needs to be changed, the drain plug at the bottom of the engine oil pan can be easily exposed, so that the protective plate 1 does not need to be repeatedly disassembled and reassembled when changing the engine oil regularly, thus improving the convenience of use.

[0031] Each of the two positioning rods 207 has a handle 209 fixedly installed at one end, and the other end of the torsion spring 208 is fixedly connected to the handle 209. A fixing block 210 is symmetrically installed on one side of the baffle 205 at the bottom of the protective plate 1. A connecting groove 211 is provided through one side of each fixing block 210, and the positioning rod 207 is inserted into the connecting groove 211, allowing the positioning rod 207 to automatically reset after rotation. Limit grooves 212 are symmetrically provided on both sides of the inside of the connecting groove 211. On the outside of the positioning rod 207, symmetrically mounted limit blocks 213 are installed on one side of the fixed block 210, and one side of the limit block 213 abuts against the fixed block 210 to limit the positioning rod 207. On one side of the positioning frame 206, symmetrically mounted limit frames 214 are installed between the two positioning rods 207, and each of the two limit frames 214 has a sliding rod 215 slidably connected inside. One end of the moving rod 215 is fixedly mounted with a limit plate 216, and one side of the limit plate 216 is in close contact with the handle 209. The handle 209 can be limited. A mounting bracket 217 is fixedly installed on the middle of one side of the positioning bracket 206. A screw 218 is rotatably connected inside the mounting bracket 217.

The end of the connecting rod 222 away from the movable block 220 is hinged to the moving rod 215. The mounting bracket 217 has through slots 221 symmetrically opened on both sides, so that the movement of the movable block 220 can drive the moving rod 215 to move. A knurled screw 223 is passed through one side of the knob 219. The mounting bracket 217 has several threaded holes 224 circumferentially opened on the side away from the positioning bracket 206. The knurled screw 223 is threadedly connected to the threaded holes 224, which can position the knob 219.

[0032] Working principle: Before using this type of prefabricated automotive chassis protection structure, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, the protective plate 1 is installed on the car chassis through the mounting hole 101. The baffle 205 is located below the engine oil pan. When changing the engine oil, the handle 209 can be held and rotated, causing the positioning rod 207 to rotate 90 degrees. After the positioning rod 207 rotates, the limiting block 213 can be aligned with the limiting groove 212. At the same time, the rotation of the positioning rod 207 can cause the torsion spring 208 to deform. Then, the baffle 205 can be moved, causing the limiting block 213 to exit from the limiting groove 212. After the baffle 205 moves, it causes the movable frame 203 to slide on the support plate 202. After the baffle 205 moves, the movable frame 203 contacts the magnet 2011 on one side of the support frame 201. The movable frame 203 is made of metal and can be attracted to the magnet 2011. The baffle 205 no longer obstructs the rectangular groove 204, allowing the engine to... The engine oil pan is exposed for easy oil changes. Afterwards, the baffle 205 is reset, the movable bracket 203 is disengaged from the magnet 2011, and the handle 209 is turned to rotate the positioning rod 207, aligning the limit block 213 with the limit groove 212. As the baffle 205 moves, the limit block 213 passes through the limit groove 212. Then, the handle 209 is released, and the positioning rod 207 is reset and rotated under the action of the torsion spring 208, causing the limit block 213 to be misaligned with the limit groove 212, thus positioning the baffle 205. At this time, the movable bracket 203 is in contact with the other side support bracket 201, allowing the car chassis to be protected by the protective plate 1. When the engine oil needs to be changed, the drain plug at the bottom of the engine oil pan is exposed, so that the protective plate 1 does not need to be repeatedly disassembled and reassembled when changing the engine oil regularly, improving the convenience of use.

[0033] Before turning the handle 209, turn the knurled screw 223 to disengage it from the threaded hole 224, causing the knob 219 to lose its limit. Turning the knob 219 will then drive the screw 218 to rotate. After the screw 218 rotates, it will move the movable block 220, which in turn will cause the connecting rod 222 to rotate and push the moving rod 215 to move. This will cause the moving rod 215 to bring the two limit plates 216 closer together, allowing the handle 209 to lose its limit. After the baffle 205 returns to its original position, the knob 219 can be turned in the opposite direction to make the two limit plates 216 fit against the handle 209. Then, the knurled screw 223 can be screwed through the knob 219 into the threaded hole 224 to position the screw 218, which in turn positions the handle 209. This prevents the handle 209 from rotating easily while the car is in motion, avoids accidental movement of the baffle 205, and improves practicality.
