Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides an automotive dashboard guard plate assembly, including an upper guard plate 1 and a lower guard plate 2. The upper end of the upper guard plate 1 is provided with two sets of hexagon socket head cap screws 4, and the outer wall of the lower guard plate 2 is provided with two sets of hexagon socket head cap screws 5. The inner wall of the upper guard plate 1 is installed with straight mesh ribs 6, and the inner wall of the lower guard plate 2 is installed with arc-shaped mesh ribs 8. The inner wall of the upper guard plate 1 is installed with multiple sets of first-type clips 10 for fitting into first-type slots on the automotive dashboard body, and the inner wall of the lower guard plate 2 is installed with multiple sets of second-type clips 11 for fitting into the automotive dashboard. The second slot on the main body is compatible. One end of the upper guard plate 1 is in contact with one end of the lower guard plate 2. Two sets of fixing blocks 12 are installed on the inner wall of the lower guard plate 2. Two sets of limiting seats 13 are installed on the inner wall of the upper guard plate 1. One end of each of the two sets of fixing blocks 12 is welded with a plug 16. The upper end of each of the two sets of plugs 16 is provided with a threaded hole 17. The two sets of plugs 16 are respectively inserted into the interior of the two sets of limiting seats 13. The lower part of the two sets of internal hexagon bolts 4 passes through the upper end of the upper guard plate 1 and the two sets of limiting seats 13, and is threadedly connected to the two sets of threaded holes 17 respectively.

[0025] Side guard plates 3 are provided on one side of both the upper guard plate 1 and the lower guard plate 2. Square hole blocks 14 are installed on the inner walls of both the upper guard plate 1 and the lower guard plate 2. Two sets of threaded clamping blocks 15 are installed on one side of the side guard plate 3. The two sets of threaded clamping blocks 15 are respectively inserted into the interior of the two sets of square hole blocks 14. The lower parts of the two sets of internal hexagon bolts 25 pass through the upper guard plate 1 and the lower guard plate 2 and the upper ends of the two sets of square hole blocks 14, and are respectively threadedly connected to the two sets of threaded clamping blocks 15.

[0026] The specific settings and functions of this embodiment are described in detail below. Two sets of internal hexagonal bolts 4 are installed through the upper end of the upper guard plate 1. The bolt heads are embedded in the pre-set countersunk holes on the surface of the upper guard plate 1 and are flush with the plate surface. Straight grid ribs 6 are fixedly installed on the inner wall by welding. The ribs adopt a grid structure with crisscrossing grids and the grid units are square. Multiple sets of No. 1 buckles 10 are also evenly distributed on the inner wall of the upper guard plate 1. The buckles are inverted "L" shape and are used to form an interference fit with the No. 1 slots set on the corresponding part of the instrument panel body. Two sets of limiting seats 13 are symmetrically installed on the inner wall of the upper guard plate 1 near the lower guard plate 2. The limiting seats 13 are hollow cuboid structures with internal space dimensions that match the insert block 16. At the same time, a square hole block 14 is fixedly installed on the inner wall of the side guard plate 1 facing the side guard plate 3. The square hole block 14 has a rectangular through hole that matches the threaded buckle block 15.

[0027] Two sets of internal hexagon bolts 25 are installed through the corresponding positions on the outer wall of the lower guard plate 2, also using a countersunk hole design. An arc-shaped mesh rib 8 is welded to the inner wall, with the rib curvature perfectly matching the arc contour of the inner wall of the lower guard plate 2. The mesh units are fan-shaped and evenly distributed along the arc direction. The rib thickness is consistent with the straight mesh rib 6. Multiple sets of second-order clips 11 are also evenly distributed on the inner wall of the lower guard plate 2. Their structure is identical to the first-order clip 10, only their dimensions are adjusted to adapt to the installation position of the lower guard plate 2, for fitting with the second-order slot on the vehicle's dashboard body. 2. Two sets of fixing blocks 12 are installed on the inner wall of the upper guard plate 1 at the position corresponding to the limiting seat 13. The fixing blocks 12 are fixed to the inner wall of the lower guard plate 2 by welding. The ends of the two sets of fixing blocks 12 away from the lower guard plate 2 are integrally welded with insert blocks 16. The insert blocks 16 are cuboid structures. The upper ends of the two sets of insert blocks 16 are threaded holes 17. The diameter of the threaded holes 17 matches the outer diameter of the internal hex bolt 4. On the inner wall of the side of the lower guard plate 2 facing the side guard plate 3, a square hole block 14 is also fixedly installed, which is on the same horizontal line as the square hole block 14 on the upper guard plate 1.

[0028] One end of the upper guard plate 1 is in close contact with the edge of one end of the lower guard plate 2. The contact area is treated with rounded corners. The two sets of inserts 16 are precisely inserted into the interior of the two sets of limit seats 13. The outer wall of the insert 16 fits against the inner wall of the limit seat 13. The lower part of the two sets of internal hex bolts 4 passes through the plate surface of the upper guard plate 1 and the upper end face of the two sets of limit seats 13 in sequence, and finally forms a tight threaded connection with the threaded holes 17 on the two sets of inserts 16.

[0029] Two sets of threaded clips 15 are vertically welded to one side of the side guard plate 3. The distance between the two sets of clips is the same as the distance between the square hole blocks 14 on the upper guard plate 1 and the lower guard plate 2. The two sets of threaded clips 15 are inserted into the corresponding two sets of square hole blocks 14. The lower parts of the two sets of internal hexagon bolts 25 pass through the plate surface of the lower guard plate 2, the plate surface of the upper guard plate 1 and the upper end face of the corresponding two sets of square hole blocks 14 in sequence, and finally form a threaded connection with the two sets of threaded clips 15.

[0030] Both the straight mesh ribs 6 and the arc-shaped mesh ribs 8 are made of 6061 aluminum alloy and the surface is anodized to form an oxide film with a thickness of 5-10μm, which improves their corrosion resistance and wear resistance.

[0031] Both buckle 10 and buckle 11 are injection molded from modified POM material, which has excellent elasticity and wear resistance. The snap-fit ​​parts of the buckles are chamfered with 0.5mm to facilitate smooth insertion into the slot during installation.

[0032] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a sound insulation board 7 is installed at the lower end of the straight mesh rib 6, and a sound insulation board 9 is installed on the inner wall of the arc-shaped mesh rib 8.

[0033] The overall effect of this embodiment is that the lower end of the straight grid ribs 6 is attached to the No. 1 sound insulation board 7 with environmentally friendly adhesive. A buffer gap of 1-2mm is reserved between the edge of the No. 1 sound insulation board 7 and the inner wall edge of the upper guard plate 1. The inner wall of the arc-shaped grid ribs 8 is attached to the No. 2 sound insulation board 9 with adhesive. The installation method is the same as that of the No. 1 sound insulation board 7. Both the No. 1 sound insulation board 7 and the No. 2 sound insulation board 9 are made of high-density polyester fiber sound insulation cotton and butyl rubber damping layer. The two layers are bonded together by hot pressing.

[0034] The usage method and working principle of this device are as follows: First, the insert 16 on the lower guard plate 2 is precisely inserted into the limiting seat 13 of the upper guard plate 1. The tight fit between the insert 16 and the inner wall of the limiting seat 13 achieves initial positioning and restricts the relative movement of the two in the horizontal direction. Then, the hexagon socket bolt 4 passes through the upper guard plate 1 and the limiting seat 13 and is connected to the threaded hole 17 of the insert 16. The axial force of the bolt firmly fixes the two together, preventing separation in the vertical direction and ensuring that the upper guard plate 1 and the lower guard plate 2 form a stable overall structure.

[0035] The connection between the side guard plate 3 and the upper guard plate 1 and the lower guard plate 2 also follows the double fixing principle. The threaded clip 15 of the side guard plate 3 is inserted into the corresponding square hole block 14. The pre-positioning is achieved by the fit between the clip and the inner wall of the square hole. Then, the internal hex bolt 25 passes through the plate surface and the square hole block 14 and connects with the threaded clip 15 to further enhance the connection strength, so that the side guard plate 3 and the upper and lower guard plates form a complete closed structure to avoid the loosening of parts due to vehicle vibration.

[0036] The guard plate assembly is fixed to the vehicle dashboard body by clips. Clip 10 of the upper guard plate 1 and clip 11 of the lower guard plate 2 form an interference fit with the first and second slots on the dashboard body, respectively. The inverted "L" shaped structure of the clips is inserted into the slots through elastic deformation during installation. After installation, the elastic restoring force of the material is used to firmly hold it in the slots to prevent the guard plate assembly from shifting as a whole. At the same time, with the auxiliary fixing of bolt connection, it is ensured that there will be no relative shaking during vehicle operation.

[0037] In terms of structural reinforcement, the straight grid ribs 6 on the inner wall of the upper guard plate 1 adopt a crisscross square grid design. When the guard plate is subjected to external impact, the grid structure can evenly distribute the force to the entire rib body. The high strength characteristics of aluminum alloy material are used to resist deformation and prevent the upper guard plate 1 from being damaged due to excessive local stress. The arc-shaped grid ribs 8 of the lower guard plate 2 fit the arc of the inner wall and can specifically bear the impact force and vibration load in the area of ​​the lower guard plate 2, optimize the force transmission path, disperse the external force to a larger range, and improve the impact resistance of the lower guard plate 2.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
