[0052] Please see Figure 1 and Figure 5 This utility model provides a technical solution: an easily removable automotive chassis protective plate, comprising:

[0053] The protective plate body 1 has heat dissipation holes 2 on its bottom surface;

[0054] An elastic buffer assembly 3 is fixedly arranged on the bottom surface of the protective plate body 1 along the length direction;

[0055] The lower end of the elastic buffer component 3 protrudes from the bottom surface of the protective plate body 1;

[0056] The elastic buffer component 3 and the heat dissipation through hole 2 are misaligned.

[0057] Specifically, in this embodiment, the protective plate body 1 is made of alloy steel to provide sufficient protection; the elastic buffer assembly 3 is formed by using an elastic element with sufficient manufacturing effect or by combining an elastic element with other structures to provide elastic buffer protection against impacts to the vehicle chassis.

[0058] Furthermore, the protective plate body 1 with heat dissipation holes 2 is installed under the corresponding engine position on the car chassis to protect the engine; the elastic buffer component 3 on the bottom surface of the protective plate body 1 provides elastic buffering against bumps and impacts, avoiding direct force on the protective plate body and reducing the probability of deformation of the protective plate body.

[0059] More specifically, an airflow channel is formed between the elastic buffer component 3 and the heat dissipation hole 2 for heat dissipation;

[0060] Understandably, multiple elastic buffer components 3 and heat dissipation holes 2 are arranged to ensure heat dissipation and elastic protection.

[0061] In some embodiments, the resilient buffer component 3 includes:

[0062] The first arc-shaped elastic metal sheet 31a and the second arc-shaped elastic metal sheet 32a are both provided symmetrically in front and behind;

[0063] The upper ends of the first arc-shaped elastic metal sheet 31a and the second arc-shaped elastic metal sheet 32a are fixedly connected to the lower edge of the corresponding heat dissipation through hole 2;

[0064] The lower ends of the first arc-shaped elastic metal sheet 31a and the second arc-shaped elastic metal sheet 32a are inclined outward.

[0065] Specifically, in this embodiment, the first arc-shaped elastic metal sheet 31a and the second arc-shaped elastic metal sheet 32a are both made of spring steel;

[0066] Furthermore, the lower ends of the first arc-shaped elastic metal sheet 31a and the second arc-shaped elastic metal sheet 32a are inclined outward, making it easier for them to undergo elastic deformation when impacted, thus buffering the force and protecting the protective plate body 1.

[0067] More specifically, two first arc-shaped elastic metal sheets 31a and two second arc-shaped elastic metal sheets 32a are symmetrically fixed at the lower edge of the heat dissipation hole 2, and are evenly distributed in a petal shape to distribute the force.

[0068] The number of elastic buffer components 3 matches the number of heat dissipation holes 2.

[0069] In some embodiments, the protective panel body 1 includes:

[0070] The first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14 are spliced ​​together end to end;

[0071] The bottom surfaces of the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14 are perforated with connecting bolts 16, the upper ends of which are screwed into the reserved screw holes on the vehicle chassis.

[0072] Ear plates 15 are fixedly connected to the edges of the first protective plate 11 and the third protective plate 13, and are fixedly connected to the reserved screw holes on the vehicle chassis by bolts.

[0073] Specifically in this embodiment, the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14 are spliced ​​together end to end. The splicing here is a non-connected and fixed splicing method, and gaps are left at the splicing points so that each protective plate has a certain amount of movement when it is impacted.

[0074] Furthermore, the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14 are fixed to the vehicle chassis by connecting bolts 16, which are distributed at the front and rear edges of each protective plate.

[0075] More specifically, the ear plates 15 provided on the edges of the first protective plate 11 and the third protective plate 13 are fixed to the vehicle chassis by bolts, thereby enhancing the stability of the connection and fixation between the two and the vehicle chassis.

[0076] In some embodiments, the left and right edges of the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14 are all bent upward to form a retaining edge 4;

[0077] The angle between the guard 4 and the corresponding first protective plate 11, second protective plate 12, third protective plate 13 and fourth protective plate 14 is an obtuse angle.

[0078] Specifically in this embodiment, the design of the retaining edge 4 expands the protective area of ​​the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14;

[0079] Furthermore, the side of the guard edge 4 is a sloping surface, which can guide the colliding object outward when a collision occurs on the outer wall of the guard edge 4, thereby reducing the impact on the engine protected by the protective plate body 1.

[0080] In some embodiments, the dimensions of the first protective plate 11, the second protective plate 12, the third protective plate 13, and the fourth protective plate 14 decrease sequentially;

[0081] The first protective plate 11 has raised reinforcing ribs 5 formed by cold pressing at the bottom edge.

[0082] Specifically, in this embodiment, the raised reinforcing ribs 5 are used to enhance the mechanical strength of the first protective plate 11, which has a larger area, and ensure its impact resistance.

[0083] In some embodiments, the heat dissipation hole 2 is elongated oval in shape, and the elongated oval heat dissipation hole 2 ensures the heat dissipation area of ​​the bottom surface of the protective plate body 1.

[0084] Furthermore, the edges of the heat dissipation through-hole 2 are rounded to avoid stress concentration.

[0085] In some embodiments, a splicing structure 6 is provided between the first protective plate 11, the second protective plate 12, the third protective plate 13, and the fourth protective plate 14, comprising:

[0086] The trapezoidal protrusion 62 is integrally formed on one side of the connection between the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14.

[0087] A trapezoidal groove 61 is formed on the other side of the connection between the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14;

[0088] The trapezoidal protrusion 62 is inserted into the corresponding trapezoidal groove 61.

[0089] Specifically in this embodiment, the first protective plate 11, the second protective plate 12, the third protective plate 13 and the fourth protective plate 14 are engaged together end to end by trapezoidal protrusions 62 and trapezoidal grooves 61, with gaps left between them.

[0090] Furthermore, when subjected to impact, the movement of the gaps allows the first protective plate 11, the second protective plate 12, the third protective plate 13, and the fourth protective plate 14 to move independently; when the impact force is large, the first protective plate 11, the second protective plate 12, the third protective plate 13, and the fourth protective plate 14 are closely attached to each other to transmit and disperse the impact. Example

[0091] Please see Figure 2 and Figure 6 The difference between this embodiment and Embodiment 1 is that the elastic buffer component 3 includes:

[0092] The first elastic metal inclined plate 32b has one end bent to the horizontal to form a strip connecting plate 31b;

[0093] A fixing bolt 34b is screwed between the strip connecting plate 31b and the bottom surface of the protective plate body 1;

[0094] The other end of the first elastic metal inclined plate 32b is bent to a horizontal position to form a horizontal plate 33b.

[0095] Specifically, in this embodiment, the first elastic metal inclined plate 32b is made of spring steel;

[0096] Furthermore, the first elastic metal inclined plate 32b is inclined, making it easier to undergo elastic deformation to buffer the force when subjected to impact;

[0097] More specifically, there are four elastic buffer components 3, one of which is provided on the bottom surface of each protective plate; the strip connecting plate 31b is fixed to one edge of the bottom surface of each protective plate by fixing bolts 34b, and the first elastic metal inclined plate 32b and the horizontal plate 33b cover the bottom of the corresponding protective plate.

[0098] Understandably, when the horizontal plate 33b first comes into contact with the collision from below, it better compresses the deformation of the first elastic metal inclined plate 32b, thus protecting the protective plate body 1. Example

[0099] Please see Figure 3 and Figure 7 The difference between this embodiment and Embodiment 1 is that the elastic buffer component 3 includes:

[0100] A strip-shaped groove 31c is horizontally opened on the bottom surface of the protective plate body 1;

[0101] A connecting plate 32c is inserted into and welded into the strip groove 31c, and its lower end is bent to form a second elastic metal inclined plate 33c.

[0102] Specifically in this embodiment, the connecting plate 32c is inserted into the strip groove 31c and solder is injected into the gap between the two to improve the connection and fixing strength.

[0103] Furthermore, the second elastic metal inclined plate 33c formed by bending the lower end of the connecting plate 32c is made of spring steel. When subjected to impact, it undergoes elastic deformation to buffer the force and protect the protective plate body 1. Example

[0104] Please see Figure 4 and Figure 8 The difference between this embodiment and Embodiment 1 is that the elastic buffer component 3 includes:

[0105] A rigid spring 32d is uniformly fixed between the top surface of the baffle 31d and the bottom surface of the protective plate body 1.

[0106] Specifically, in this embodiment, the baffle 31d is made of alloy steel;

[0107] Furthermore, multiple rigid springs 32d are fixed between the baffle 31d and the bottom surface of the protective plate body 1, arranged in a regular rectangular array. The collision is buffered by the elastic deformation of the multiple rigid springs 32d under force, thus protecting the protective plate body 1.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
