[0049] ​​​​In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0050] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element.

[0051] The terms "first", "second", "third", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or an indicated number of technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "several" is two or more than two, unless otherwise specifically limited.

[0052] The "front", "back", "inside", "outside", "top", "bottom" and the like in the present embodiment indicate the orientation or positional relationship based on the orientation of the vehicle, wherein the head of the vehicle represents "front", the tail of the vehicle represents "back", the top of the vehicle represents "top", the bottom of the vehicle represents "bottom", the "inside" side refers to the side towards the cab, and the "outside" side refers to the side towards the outside of the cab.

[0053] In addition, the front-rear direction of the vehicle body defined in the embodiments of the present application refers to the front-rear direction of the advancing direction during vehicle driving, the left-right direction of the vehicle body defined refers to the left-right direction of the advancing direction during vehicle driving, and the up-down direction of the vehicle body defined refers to the up-down direction of the advancing direction during vehicle driving.

[0054] The middle grille, as an important component of the front part of the vehicle, not only bears functional role, but also has aesthetic design. Its core function is to allow air to flow into the engine compartment to ensure that the radiator can effectively cool the engine and prevent the engine from being damaged due to overheating. At the same time, the middle grille also plays a filtering role to prevent large particles (such as stones, leaves, etc.) from entering the interior of the engine compartment, thereby protecting the engine and other precision parts from damage.

[0055] However, the existing technology of the middle grid, especially the middle net plate part, has some design defects and use problems. The middle net plate usually adopts a wire mesh or similar grid structure, which can meet the basic needs of ventilation and filtration, but the inventors find that the middle net is prone to deformation or collapse. The reasons for deformation may include the following aspects: first, the material used for the middle net plate may not be strong enough to withstand the wind pressure, vibration or external impact (such as flying stone impact) during high-speed driving, resulting in deformation of its structure. Second, the design of some middle net plates may be too thin or lack sufficient support structure, especially in high temperature environment, the thermal expansion and cold shrinkage of the material may cause its shape to change, thereby causing collapse. Third, during driving, especially in bad road conditions or extreme weather conditions, the middle net plate is prone to be eroded by external environment, such as rain, dust, salt mist, etc., which may accelerate the corrosion and aging of the material, further aggravating the deformation problem.

[0056] When the middle net plate deforms or collapses, not only its original function will be affected, but also other problems may be caused. For example, the deformed middle net plate may rub against the decorative surface (such as bumper, logo, etc.) of the front part of the vehicle, causing the protective layer on the surface of the decorative surface to wear or scratch. This not only affects the appearance of the vehicle, but also may expose the decorative surface to the external environment, accelerating its aging or corrosion.

[0057] In order to solve the problem of deformation and collapse of the middle net plate, please refer to Figures 1 to 3 , the middle grid structure provided by the utility model is described. The middle grid structure comprises a grid frame 1, a middle net plate 2, a pressing plate 3 and a plurality of first connecting pieces 4. The middle part of the grid frame 1 is provided with a decorative part 11; the middle net plate 2 is arranged at the back of the grid frame 1; the pressing plate 3 is arranged at the back of the middle net plate 2; the pressing plate 3 is provided with a connecting part 31, and the connecting part 31 is located at the back of the decorative part 11; part of the first connecting pieces 4 pass through the outer peripheral edge of the pressing plate 3 and the outer peripheral edge of the middle net plate 2 in sequence and are connected with the outer peripheral edge of the grid frame 1; part of the first connecting pieces 4 pass through the connecting part 31 and are connected with the decorative part 11.

[0058] The grid frame 1 is the outer decoration frame of the middle grid structure, which comprises a second frame and a horizontal strip grid located in the second frame, and the horizontal strip grid is provided with a decorative part 11, and the front surface of the decorative part 11 can be provided with a decorative bright strip and other decorative structures.

[0059] The middle mesh plate 2 is limited at the front of the grating frame 1, and plays a role of blocking large particles from entering the cabin. The middle mesh plate 2 comprises a first frame 22 and a mesh plate 21 in the first frame 22, and the mesh plate 21 is made of steel wire and is arranged in a crisscross manner. The first frame 22 is arranged around the mesh plate 21 and is located at the front of the second frame of the grating frame 1. The middle mesh plate 2 is located at the front of the grating frame 1 and does not protrude from the grating frame 1, so that the second frame of the grating frame 1 can completely block the first frame 22.

[0060] The pressing plate 3 is used for fixing the middle mesh plate 2 on the grating frame 1, and the outer contour of the pressing plate 3 is matched with the outer contour of the middle mesh plate 2. Specifically, the pressing plate 3 comprises a third frame 32 and a transverse reinforcing rib 33 in the third frame 32. The transverse reinforcing rib 33 is opposite to the transverse grating, and the connecting part 31 is arranged on the transverse reinforcing rib 33 and abuts against the front and rear of the middle mesh plate 2, thereby supporting the middle mesh plate 2 and preventing the middle mesh plate 2 from collapsing and deforming.

[0061] The plurality of first connecting parts 4 are divided into two groups. One group sequentially passes through the third frame, the first frame 22 and is connected with the second frame from back to front. The other group passes through the connecting part 31 and is connected with the decoration part 11 from back to front. That is to say, the pressing plate 3, the middle mesh plate 2 and the grating frame 1 are not only fixedly connected at the outer periphery, but also fixedly connected at the middle part.

[0062] It should be noted that the above-mentioned "front", "rear" and the like represent the position of the middle mesh grating structure after being assembled to the vehicle, wherein the front represents the head of the vehicle, and the rear represents the tail of the vehicle.

[0063] Compared with the prior art, the middle mesh grating structure provided by the utility model fixes and limits the middle mesh plate 2 at the rear of the grating frame 1 through the pressing plate 3 and the plurality of first connecting parts 4, thereby improving the stability of the overall structure. The connecting part 31 is connected with the decoration part 11, and the connecting part 31 also supports the middle part of the middle mesh plate 2, thereby effectively preventing the middle mesh plate 2 from deforming and collapsing and avoiding the middle mesh plate 2 from scratching the front decoration surface of the vehicle, thereby protecting the decoration surface protection layer.

[0064] Meanwhile, the stable middle mesh plate 2 ensures smooth airflow and maintains good heat dissipation performance, thereby preventing the engine from overheating. In addition, the decoration part 11 in the grating frame 1 also improves the appearance of the front of the vehicle.

[0065] In some embodiments, there is a safety gap between the middle mesh plate 2 and the grating frame 1. The safety gap refers to the gap in the front-rear direction of the vehicle body. Specifically, the safety gap is mainly the gap between the mesh plate 21 of the middle mesh plate 2 and the transverse grating of the grating frame 1, and the safety gap is greater than or equal to 3 mm.

[0066] Due to the existence of the safety gap, it can be ensured that the middle mesh plate 2 will not directly contact the horizontal strip grid even if slight deformation occurs, avoiding the wear or damage of the decorative surface protection layer of the horizontal strip grid, and maintaining the aesthetic appearance of the vehicle appearance.

[0067] In addition, the safety gap provides sufficient buffer space for the middle mesh plate 2 to prevent it from directly contacting the grid frame 1 when subjected to external force or thermal expansion and contraction, avoiding interference or friction caused by deformation, and further protecting the structural integrity of the middle mesh plate 2 and the grid frame 1.

[0068] Furthermore, the safety gap reduces the stress concentration between the middle mesh plate 2 and the grid frame 1, reducing fatigue damage caused by long-term vibration or temperature changes, prolonging the service life of the middle grid. The safety gap also provides more fault-tolerant space for installation, facilitating precise alignment and fixation of the middle mesh plate 2, the pressing plate 3 and the grid frame 1, and also simplifying subsequent disassembly and maintenance operations.

[0069] By setting a safety gap between the middle mesh plate 2 and the grid frame 1, not only is deformation interference prevented and the decorative surface is protected, but also the heat dissipation performance is optimized, the durability is enhanced, and the installation and maintenance are simplified. At the same time, the safety gap can adapt to complex working conditions, improving the overall reliability and practicality of the middle grid structure.

[0070] In some embodiments, the above-mentioned grid frame 1 can also adopt the structure as shown in Figure 5 and Figure 6 , referring to Figure 5 and Figure 6 , the back outer periphery of the grid frame 1 and the back of the decorative part 11 are provided with a plurality of connection platforms 12, each connection platform 12 extends towards the middle mesh plate 2; a plurality of first connecting pieces 4 are connected one by one with a plurality of connection platforms 12.

[0071] Specifically, part of the connection platforms 12 are arranged on the back of the second frame, and part of the connection platforms 12 are arranged on the back of the connecting part 31. It should be noted that each connection platform 12 only extends towards the middle mesh plate 2, but does not abut against the middle mesh plate 2. There is also a safety gap between the connection platform 12 and the middle mesh plate 2.

[0072] The main function of the connection platform 12 is to be fixedly connected with the first connecting piece 4, so as to tightly combine the grid frame 1, the middle mesh plate 2 and the pressing plate 3 together. Through the corresponding connection of the plurality of connection platforms 12 and the first connecting pieces 4, the whole middle grid structure realizes multi-point fixation, which not only improves the stability and rigidity of the overall structure, but also effectively prevents the middle mesh plate 2 from deforming or collapsing during long-term use.

[0073] The connecting table 12 provides a clear mounting position for the first connecting piece 4, facilitating accurate alignment and fixation of the middle mesh plate 2, the pressing plate 3 and the grille frame 1, and simplifying subsequent disassembly and maintenance operations. Since the first connecting piece 4 passes through the pressing plate 3 and the middle mesh plate 2 from back to front, the connecting table 12 extends towards the middle mesh plate 2, which can also increase the connection strength with the first connecting piece 4, avoiding damage to the grille frame 1 due to excessive stress.

[0074] The connecting table 12 is connected to the plurality of first connecting pieces 4 one by one, ensuring that the stress at each connection point is more uniform, avoiding stress concentration, thereby prolonging the service life of the middle mesh grille. In addition, the multi-point fixation design of the connecting table 12 can effectively disperse external loads such as wind pressure during high-speed driving, vibration under bumpy road conditions and external impact force, further enhancing the anti-deformation ability of the middle mesh grille. Furthermore, the design of the connecting table 12 makes the installation position of the first connecting piece 4 more concealed, maintaining the neatness and aesthetics of the appearance of the middle mesh grille structure, and improving the overall visual effect of the front of the vehicle.

[0075] A safety gap is also reserved between the connecting table 12 and the middle mesh plate 2, ensuring that the middle mesh plate 2 does not come into direct contact with the connecting table 12 due to thermal expansion and contraction or external forces, avoiding damage caused by friction or extrusion.

[0076] By setting multiple connecting tables 12 on the back of the grille frame 1 and connecting them to the first connecting pieces 4, while reserving a safety gap between the connecting table 12 and the middle mesh plate 2, this design further enhances structural stability, disperses stress, protects the middle mesh plate 2, optimizes heat dissipation performance, and simplifies installation and maintenance. In addition, the design of the connecting table 12 also improves the aesthetics of the middle mesh grille, and overall improves the reliability and practicality of the middle mesh grille structure.

[0077] Preferably, referring to Figure 5 On the basis of the above embodiments, among the plurality of connecting tables 12 on the outer periphery of the back of the grille frame 1, part of the connecting tables 12 are distributed on the upper and lower side edges of the grille frame 1, and part of the connecting tables 12 are distributed on the left and right side edges of the grille frame 1, that is, the plurality of connecting tables 12 are arranged at intervals around the second frame of the grille frame 1.

[0078] The connecting table 12 is arranged at intervals around the second frame of the grille frame 1, connected to the middle mesh plate 2 and the pressing plate 3 through the first connecting piece 4, forming a ring-shaped multi-point fixation, which not only makes the stress on the middle mesh plate 2 more uniform, but also avoids displacement of the middle mesh plate 2 in the left-right direction and the up-down direction of the vehicle body, enhancing the anti-deformation ability of the middle mesh plate 2, especially when the vehicle is subjected to complex external forces during driving, the structural integrity can be better maintained.

[0079] The connection table 12 is arranged in a second frame of the grid frame 1, which achieves all-around multi-point fixing of the middle mesh plate 2, enhances the stability of the middle mesh grid structure, uniformly disperses stress, and improves the anti-deformation capability.

[0080] Preferably, the first connecting piece 4 is a threaded connecting piece, such as a screw or a bolt. The threaded connection of the first connecting piece 4 can provide stronger connecting force, bear greater tension and shear force, and ensure that the connection between the grid frame 1, the middle mesh plate 2, and the pressing plate 3 is more firm, thereby effectively preventing loosening or falling off due to vibration or external force.

[0081] In some embodiments, the pressing plate 3 can adopt a structure as shown in Figure 3 , which is described in detail in Figure 3 . The pressing plate 3 includes a third frame 32 and a plurality of transverse reinforcing ribs 33 formed in the third frame 32. The middle part of at least two transverse reinforcing ribs 33 is provided with a clearance, and the connecting part 31 is arranged in the clearance and connected with the transverse reinforcing rib 33.

[0082] The transverse reinforcing rib 33 is opposite to the transverse grid of the grid frame 1 in front and back, that is, the transverse reinforcing rib 33 is shielded by the transverse grid and cannot be observed.

[0083] The plurality of first connecting pieces 4 are annularly and spacedly distributed on the third frame 32 and connected with the plurality of connection tables 12 one by one, which is used to ensure that the pressing plate 3 and the middle mesh plate 2 are uniformly stressed and the middle mesh plate 2 is prevented from moving up, down, left, and right.

[0084] The transverse reinforcing rib 33 extends along the left-right direction of the vehicle body and is spacedly distributed along the up-down direction of the vehicle body. The transverse reinforcing rib 33 is used to increase the overall strength of the pressing plate 3 and prevent the third frame 32 from being deformed. The connecting part 31 is connected with the at least two transverse reinforcing ribs 33, which can ensure the connecting strength of the connecting part 31 so that the connecting part 31 has stable front and back supporting functions.

[0085] In some embodiments, the middle mesh grid structure can also adopt a structure as shown in Figure 1 , Figure 2 and Figure 3 , which is described in detail in Figure 1 , Figure 2 and Figure 3 . The middle mesh grid structure further includes a middle mesh framework 5 located at the back of the pressing plate 3. The grid frame 1 and / or the pressing plate 3 is / are provided with a plurality of second connecting pieces 6, and each second connecting piece 6 is connected with the middle mesh framework 5.

[0086] The middle net framework 5 is a fixed support of the middle net grid structure, which is fixedly connected with the vehicle body, that is, the grille frame 1, the middle net plate 2 and the pressing plate 3 are assembled and fixed through the middle net framework 5. The middle net framework 5 is fixedly connected with the vehicle body, so that the whole middle net grid structure (including the grille frame 1, the middle net plate 2 and the pressing plate 3) obtains a stronger supporting foundation, significantly improves the overall rigidity, and effectively prevents the middle net plate 2 from deforming or collapsing.

[0087] The middle net framework 5 as a fixed support is connected with the pressing plate 3 and the grille frame 1 through the second connecting piece 6, forming a multi-layer stable connecting structure, and further enhancing the anti-deformation ability. The middle net framework 5 is located behind the pressing plate 3, so that the installation position of the second connecting piece 6 is more concealed, and the neatness and beauty of the appearance of the middle net grid structure are maintained.

[0088] It should be noted that the above-mentioned second connecting piece 6 can be separately provided on the grille frame 1, or separately provided on the pressing plate 3, or simultaneously provided on the grille frame 1 and the pressing plate 3.

[0089] In some embodiments, the above-mentioned plurality of second connecting pieces 6 can adopt the structures as shown in Figure 3 , Figure 5 and Figure 6 , and refer to Figure 3 , Figure 5 and Figure 6 . The plurality of second connecting pieces 6 are distributed on the upper and lower side edges and the left and right side edges of the back surface of the grille frame 1, that is, the plurality of second connecting pieces 6 are arranged at intervals around the second frame of the grille frame 1. Preferably, the plurality of second connecting pieces 6 are staggered with the plurality of connecting tables 12. Each second connecting piece 6 passes through the middle net plate 2, the pressing plate 3 in sequence from front to back, and is connected with the middle net framework 5.

[0090] The second connecting piece 6 is arranged on the grille frame 1 to connect the grille frame 1 with the middle net framework 5, and compared with the connecting mode arranged on the pressing plate 3, the second connecting piece 6 can also form a press-fit fixing for the middle net plate 2 and the pressing plate 3, forming a stable multi-layer connecting structure, which can better resist the vibration and impact during vehicle driving, and further improve the stability of the middle net grid structure.

[0091] The second connecting piece 6 is distributed on the upper, lower, left and right four side edges of the back surface of the grille frame 1, and is connected with the middle net framework 5 through the middle net plate 2 and the pressing plate 3, forming a full-range multi-point fixed structure, so that the stress is more uniform, stress concentration is avoided, local deformation or damage caused by long-term use or complex working conditions is reduced, and the overall rigidity of the middle net grid structure is significantly improved.

[0092] The second connecting piece 6 is distributed on the back surface of the grille frame 1, and the installation position is more concealed, so that the neatness and beauty of the appearance of the middle net grid structure are maintained.

[0093] In some embodiments, the second connecting member 6 and the middle net framework 5 can be connected by the structure as shown in Figure 3 , Figure 4 and Figure 5 . Referring to Figure 3 , Figure 4 and Figure 5 , the middle net framework 5 is provided with a plurality of clamping holes 51, and the plurality of second connecting members 6 are clamped one by one with the plurality of clamping holes 51.

[0094] Specifically, the second connecting member 6 is a clamping member, which has a radial elastic freedom parallel to the clamping hole 51. After the second connecting member 6 partially penetrates the clamping hole 51, it can still abut against the back of the middle net framework 5 to avoid falling out of the clamping hole 51. Moreover, the elastic clamping design can effectively resist the vibration and impact during the driving of the vehicle, preventing the second connecting member 6 from loosening or falling off due to vibration.

[0095] The second connecting member 6 and the middle net framework 5 are connected by clamping, which does not require the use of additional tools or complex operations, reduces the installation difficulty and time cost, simplifies the installation steps, and realizes the rapid assembly of the grille frame 1 and the middle net framework 5.

[0096] Through the elastic clamping of the plurality of second connecting members 6 and the clamping holes 51, a multi-point elastic fixing structure is formed between the middle net framework 5 and the grille frame 1, the middle net plate 2 and the pressing plate 3, further enhancing the overall rigidity of the middle net grille.

[0097] The clamping hole 51 is designed on the middle net framework 5, so that the clamping position of the second connecting member 6 is more concealed, maintaining the neatness and aesthetics of the appearance of the middle net grille.

[0098] By providing a plurality of clamping holes 51 on the middle net framework 5 and clamping the plurality of second connecting members 6 one by one with the clamping holes 51, the design further enhances the connection convenience, stability and overall rigidity of the middle net grille structure, while improving the aesthetics and durability.

[0099] In some embodiments, the grille frame 1 and the middle net framework 5 can also be connected by the structure as shown in Figure 4 , Figure 5 and Figure 6 . Referring to Figure 4 , Figure 5 and Figure 6 , the four corner points of the grille frame 1 are connected with the middle net framework 5 by fasteners 7 respectively; the fasteners 7 have elastic pre-tightening force.

[0100] The grille frame 1 and the grille skeleton 5 are connected by fasteners 7. By setting fasteners 7 at the four corner points of the grille frame 1, a symmetrical fixing structure is formed, making the connection between the grille frame 1 and the grille skeleton 5 more stable and improving the overall rigidity of the grille structure. Moreover, the four-corner fixing design makes the grille structure more symmetrical and harmonious, improving the overall visual effect of the front of the vehicle.

[0101] Preferably, the fastener 7 is a threaded component, such as a combination of a bolt and a leaf nut. The leaf nut provides elastic preload. The elastic preload provided by the leaf nut allows the bolt to automatically adjust and maintain a stable tightness during connection, effectively preventing loosening due to vibration or impact. Moreover, the elastic preload design can better resist high-frequency vibrations during vehicle operation, ensuring a long-term stable connection between the grille frame 1 and the grille skeleton 5.

[0102] The combination design of bolts and spring nuts allows for quick disassembly and replacement of the connection between the grid frame 1 and the central grid skeleton 5, reducing maintenance costs and time.

[0103] In some embodiments, the aforementioned grille plate 2 and grille frame 5 can be connected by, for example, Figure 1 and Figure 3 The structure shown is described in the following document. Figure 1 and Figure 3 The central mesh plate 2 includes a mesh plate 21 and a first frame 22 formed on the outer periphery of the mesh plate 21; the central mesh frame 5 has weight reduction holes 52, which are directly opposite to the front and back of the mesh plate 21.

[0104] Specifically, in the front-rear direction of the vehicle body, the upper half of the grille frame 5 corresponds to the grille panel 2 front-rear, and the lower half of the grille frame 5 extends downward relative to the grille panel 2. The weight reduction hole 52 is opened in the upper half of the grille frame 5.

[0105] The weight-reducing holes 52 on the grille frame 5 are aligned front and rear with the mesh plate 21, effectively reducing the amount of material used in the grille frame 5, thereby reducing the overall weight of the grille structure. This weight reduction helps reduce the overall load on the vehicle, thus improving fuel efficiency and reducing energy consumption. Furthermore, the alignment of the weight-reducing holes 52 with the mesh plate 21 ensures that air can pass smoothly through the mesh plate 21 and the grille frame 5, maintaining efficient heat dissipation performance.

[0106] The first frame 22 along the outer perimeter of the mesh plate 21 enhances the overall rigidity of the mesh plate 2, preventing the mesh plate 21 from deforming or being damaged by external forces or vibrations. The design of the weight-reducing holes 52 reduces weight without significantly weakening the structural strength of the mesh frame 5, ensuring the stability of the overall structure.

[0107] Based on the same inventive concept, the embodiment of the application further provides a vehicle comprising the above-mentioned middle mesh grating structure.

[0108] The vehicle provided by the utility model solves the problem of deformation and collapse of the middle mesh grating structure, enhances the structural stability, protects the decorative surface, and improves the appearance of the vehicle.

[0109] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
