DETAILED DESCRIPTION

[0037] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0038] In the present disclosure, an XY coordinate system is established for the vehicle, where the X direction is the length direction of the vehicle, and the Y direction is the width direction of the vehicle, wherein the direction indicated by the X arrow is the front direction of the vehicle, and the opposite direction is the rear direction of the vehicle. Unless otherwise specified, the directional words used, such as "inside" and "outside", refer to the inside and outside of the outline of the component or structure itself; unless otherwise specified, the terms "first" and "second" are used to distinguish one element from another, and do not have order and importance. In addition, in the description of the reference figures, the same mark in different figures represents the same element.

[0039] like Figures 1 to 14As shown, in a first aspect of the present disclosure, a protective structure of a vehicle is provided, which is used to be arranged at the bottom of a radiator 20 of the vehicle, and the protective structure 30 includes a protective plate 31, and the protective plate 31 can protect the radiator 20. When the vehicle is driving, the protective plate 31 can prevent foreign objects splashed from the road from colliding with the radiator 20. Among them, the radiator 20 can be used to dissipate heat for the engine 10 of the vehicle.

[0040] In addition, in order to ensure that the radiator 20 still has a good heat dissipation effect after adding the protective plate 31, ventilation holes 311 can be opened on the protective plate 31. When the protective structure 30 is installed on the frame 40 of the vehicle, the ventilation holes 311 can increase gas exchange between the side of the protective plate 31 close to the radiator 20 and the side away from the radiator 20, thereby improving the heat dissipation efficiency of the radiator 20. Furthermore, in order to prevent foreign objects splashed on the road from passing through the ventilation hole 311 and colliding with the radiator 20, a protective portion 312 is arranged around at least part of the periphery of the ventilation hole 311, and the protective portion 312 has an opening 70 connected to the ventilation hole 311. The orthographic projection of the protective portion 312 on the protective plate 31 covers the ventilation hole 311, so that the ventilation hole 311 is covered on the premise that the side of the protective plate 31 close to the radiator 20 and the side away from the radiator 20 can exchange gas through the ventilation hole 311, so as to reduce the occurrence of debris splashed on the ground passing through the ventilation hole 311 and colliding with the radiator 20, thereby avoiding damage to the radiator 20.

[0041] The protection portion 312 can be constructed in any suitable form. Figures 1 to 5 as well as Figures 7 to 9 As shown in , in some embodiments, the protection part 312 includes a bottom plate 3121 and a side plate 3122, the side plate 3122 is connected between the bottom plate 3121 and the protection plate 31, and the side plate 3122 extends along a portion of the periphery of the ventilation hole 311 and has at least one fracture, and the fracture is used to form an opening 70. Exemplarily, it can be understood that the bottom plate 3121 and the side plate 3122 form a similar protective cover, which can prevent some foreign matter from passing through the ventilation hole 311. The opening 70 surrounded by the bottom plate 3121, the side plate 3122 and the protection plate 31 is connected to the ventilation hole 311, so that the side of the protection plate 31 close to the radiator 20 and the side away from the radiator 20 can exchange gas.

[0042] It should be noted that, in this embodiment, the protection portion 312 and the opening 70 can be formed by stamping a plate material used to be processed into the protection plate 31 , and the specific stamping process is now briefly described.

[0043] The specific stamping process is as follows:

[0044] 1. Preparation stage:

[0045] Design a die punch according to the number, size, shape and positional relationship of the ventilation holes 311, install the punch on the punching machine, and make necessary adjustments and tests to ensure that it functions properly;

[0046] The plate prepared for processing the protective plate 31 is then placed on the workbench of the punching machine for accurate positioning.

[0047] 2. Punching protection part and cutting opening operation:

[0048] Start the punching machine, and the punch head begins to press down. On one side of the punch head, there is a special punching part, which can punch the sheet material to form the guard 312.

[0049] Meanwhile, a cutting portion is provided on the other side of the punching head, which cuts the protection portion 312 during the punching process to cut out the opening 70 .

[0050] 3. After the punching and cutting operations, the punching head will automatically rise and then take out the completed protective plate 31.

[0051] 4. Perform a quality check on the finished protective plates 31, and take out those that meet the requirements for later processing.

[0052] In other possible implementations, such as Figures 11 to 14 As shown in , the protection part 312 includes a bottom plate 3121 and a side plate 3122, the side plate 3122 is connected between the bottom plate 3121 and the protection plate 31, the side plate 3122 extends around the entire periphery of the ventilation hole 311, and at least one opening 70 is provided on the side plate 3122. Fig.11 and Fig.12 As shown, a through hole is provided on the side plate 3122, and the through hole is used to form an opening 70. Figure 13 to Figure 14 As shown, two through holes are provided on the side plate 3122, and the two through holes are respectively used to form the opening 70. It should be understood that multiple through holes can be provided on the side plate 3122 according to actual needs, and each of the multiple through holes can be used to form the opening 70, which will not be described in detail here.

[0053] Here, the processing of the protection portion 312 and the opening 70 in this embodiment is briefly described. The specific process is as follows:

[0054] 1. Use a punching machine to punch out the protective part:

[0055] Design a die punch according to the number, size, shape and positional relationship of the ventilation holes 311, install the punch on the punching machine, and make necessary adjustments and tests to ensure that it functions properly;

[0056] Then the prepared plate for processing the protective plate 31 is placed on the workbench of the punching machine for accurate positioning;

[0057] Then the punching machine is started, and the punching head begins to press down, so that the protection part 312 is formed on the plate used for processing the protection plate 31;

[0058] The stamped protection plates 31 are quality checked, and those that meet the requirements are taken out for later use, pending the subsequent cutting of the through holes on the protection portion 312 .

[0059] 2. Use a laser cutting machine to cut through holes on the side panels of the protective part:

[0060] Place the stamped sheet on the workbench of the laser cutting machine for positioning;

[0061] Then set the cutting program according to the processing parameters of the through hole (such as shape, size, position, cutting path and other parameters);

[0062] Then start the cutting machine to cut the through hole until the cutting is completed.

[0063] 3. Check the completed protective plates 31 and take out those that meet the requirements for later processing.

[0064] In some embodiments, in order to increase the gas exchange efficiency between the side of the protective plate 31 close to the radiator 20 and the side away from the radiator 20, the number of ventilation holes 311 on the protective plate 31 can be multiple, and each ventilation hole 311 is provided with a protective portion 312. In addition, the radiator 20 can also dissipate heat through the heat dissipation fan assembly 60, which will not be repeated here.

[0065] In some embodiments, the protective structure 30 further includes at least two reinforcing ribs 35 disposed on the protective plate 31 to enhance the strength of the protective plate 31. When the protective structure 30 is disposed on the vehicle frame 40, at least two reinforcing ribs 35 are arranged at intervals along the width direction of the vehicle, and at least two reinforcing ribs 35 extend along the length direction of the vehicle. A guide channel 50 is formed between two adjacent reinforcing ribs 35, and the guide channel 50 is located between the protective plate 31 and the radiator 20. The guide channel 50 can concentrate the airflow, and when the vehicle moves forward, the airflow is concentrated through the guide channel 50 to accelerate the heat dissipation of the radiator 20. In addition, the vent 311 is connected to the guide channel 50, so that the guide channel 50 can exchange airflow with the opposite side of the guide channel 50 of the protective plate 31 through the vent 311, thereby accelerating the heat dissipation of the radiator 20. In addition, the arrangement of the guide channel 50 and the vent 311 can discharge the accumulated water through the vent 311 when there is water on the protective plate 31.

[0066] In some embodiments, flanges 313 are provided at both ends of the protective plate 31 in the width direction. At least two reinforcing ribs 35 include two first reinforcing ribs 351 located at both ends of the protective plate in the width direction. The first reinforcing rib 351, the flange 313 corresponding to the position, and the protective plate 31 together form a first reinforcing beam structure 36 with a polygonal cross-section. In this way, the structural strength of the protective plate 31 can be enhanced by providing the flange 313. On this basis, the first reinforcing beam structure 36 is formed by the cooperation of the first reinforcing rib 351 and the flange 313, which can further enhance the structural strength. In addition, the first reinforcing beam structure 36 has a polygonal cross-section, that is, the first reinforcing beam structure 36 is hollow inside, which is conducive to lightweight design, and the structural strength can be significantly enhanced in the form of a hollow beam.

[0067] In the above-mentioned embodiment, the first reinforcing rib 351 may be constructed as a Z-shaped rib to be overlapped on the flange 313 and the protective plate 31 respectively, and may be connected by welding.

[0068] In some embodiments, at least two reinforcing ribs 35 include a second reinforcing rib 352 located between two first reinforcing ribs 351, and the second reinforcing rib 352 and the protective plate 31 together form a second reinforcing beam structure 37 with a polygonal cross section to increase the structural strength of the protective plate 31. The second reinforcing beam structure 37 has a polygonal cross section, that is, the second reinforcing beam structure 37 is hollow inside, which is conducive to lightweight design. In addition, the second reinforcing rib 352 can be configured as a U-shaped rib, and the two ends of the opening side of the U-shaped rib are respectively welded to the protective plate 31 to enhance the structural strength.

[0069] In some embodiments, when the protective structure 30 is installed on a vehicle, both ends of the protective plate 31 along the length direction of the vehicle are respectively connected to the vehicle frame 40 through the connecting members 33. To facilitate the installation of the protective plate 31, at least one of the connecting members 33 is connected to the protective plate 31 in an adjustable manner along the length direction and / or width direction of the vehicle.

[0070] In the above-mentioned embodiment, according to the position on the vehicle frame 40 for installing the protective structure 30 , the position of at least one connecting member 33 relative to the protective plate 31 can be adaptively adjusted to facilitate connecting the protective plate 31 to the vehicle frame 40 via the connecting member 33 .

[0071] In some embodiments, at least one of the connecting members 33 can be adjustably connected to the protective plate 31 in any appropriate form. For example, the protective structure 30 may further include a first connecting plate 32. At least one of the two connecting members 33 is adjustably connected to the protective plate 31 through the first connecting plate 32, and the first connecting plate 32 is fixedly connected to the protective plate 31. A first strip hole 321 extending in the length direction is provided on one of the first connecting plate 32 and the connected connecting member 33, and a second strip hole 3311 extending in the width direction of the vehicle is provided on the other. The first strip hole 321 and the second strip hole 3311 are provided for the first fastener to penetrate, so as to connect the first connecting plate 32 and the connecting member 33. By adjusting the relative position of the first strip hole 321 and the second strip hole 3311, the relative position of the connecting member 33 and the first connecting plate 32 is adjusted, that is, the position of the connecting member 33 relative to the protective plate 31 is adjusted. Among them, the first fastener can be a bolt and a nut, which is not limited here.

[0072] In other embodiments, the strip hole corresponding to the second strip hole 3311 on the connecting member 33 may be directly set on the protective plate 31 without introducing the first connecting plate 32. Then, the first fastener penetrates the second strip hole 3311 and the strip hole set on the protective plate 31 to connect the connecting member 33 to the protective plate 31. By adjusting the relative position of the second strip hole 3311 and the strip hole set on the protective plate 31, the relative position between the connecting member 33 and the protective plate 31 is adjusted.

[0073] In some embodiments, when the protective structure 30 is installed on the vehicle frame, some installation positions have a small operating space, which is not convenient for the use of installation tools. Therefore, the protective structure 30 may also include a second connecting plate 34, which is used to be welded to the frame 40, and at least one of the two connecting members 33 is connected to the frame 40 through the second connecting plate 34. It can also be understood that in order to facilitate the installation of the protective structure 30, the second connecting plate 34 can be fixedly connected (for example, welded) to the frame 40. The second connecting plate 34 is fixedly connected with a first connecting portion 341, and at least one of the two connecting members 33 is provided with a connecting hole 3321. The second fastener passes through the connecting hole 3321 and is connected to the first connecting portion 341 to connect the connecting member 33 and the second connecting plate 34.

[0074] In the above-mentioned embodiment, the first connection portion 341 can be provided in an appropriate form. Figures 4 to 6 As shown, the first connecting portion 341 can be configured as a nut, and the second fastener can be a bolt, which is connected to the nut after passing through the connecting hole 3321. In addition, the connecting hole 3321 can be a bar-shaped hole to facilitate adjustment of the relative position of the second connecting plate 34 and the connecting member 33.

[0075] refer to Figures 4 to 10 As shown, the present disclosure exemplarily shows an embodiment in which two connecting members 33 include a first connecting member 331 and a second connecting member 332 , wherein the first connecting member 331 is adjustably connected to the protective plate 31 through a first connecting plate 32 , and the second connecting member 332 is connected to a second connecting plate 34 .

[0076] In a second aspect of the present disclosure, a vehicle is provided, comprising a radiator 20 and the protective structure 30 as described above.

[0077] In some embodiments, the vehicle has a front side and a rear side opposite to each other along its length direction, and the opening 70 of the protective portion 312 is arranged toward the rear side of the vehicle to prevent debris brought by the wind from passing through the opening 70 of the protective portion 312 and colliding with the radiator when the vehicle moves forward.

[0078] In some embodiments, the protective plate has a first end and a second end that are opposite to each other along the length direction of the vehicle, the first end is arranged closer to the rear side of the vehicle relative to the second end, and the distance between the first end and the radiator 20 is smaller than the distance between the second end and the radiator 20, so that when the protective structure 30 is installed on the frame 40, the protective plate 31 is tilted, and the tilted protective plate 31 can speed up the discharge of accumulated water, and the distance between the second end of the protective plate 31 and the radiator 20 is large, so that more external air can enter between the radiator 20 and the protective plate 31 to enhance heat dissipation. In addition, when the protective structure 30 is installed on the vehicle, one of the first connector 331 and the second connector 332 can be extended toward the radiator 20, and the other can be extended away from the radiator 20, so as to speed up the discharge of accumulated water. Figure 2 exemplarily shown in the figure, the first connecting member 331 is arranged closer to the rear side of the vehicle relative to the second connecting member 332, the first connecting member 331 extends toward the radiator 20, and the second connecting member 332 extends away from the radiator 20. This arrangement can accelerate drainage while preventing the second connecting member 332 from blocking external air from entering between the radiator 20 and the protective plate 31.

[0079] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0080] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0081] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
