In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0057] In combination Figures 1 to 11 , in a specific embodiment of the present application, a front beam assembly is provided.

[0058] Specifically, the front beam assembly includes a front crossbeam assembly 10, a front tow hook assembly 20, and a radiator grille guard assembly 30. The front crossbeam assembly 10 includes a front crossbeam 11 and a reinforcing plate sub-assembly 12. The front crossbeam 11 is used to connect with the longitudinal beam 40 of the vehicle; the front tow hook assembly 20 is connected to the front crossbeam 11 through the reinforcing plate sub-assembly 12; the radiator grille guard assembly 30 is disposed on the lower side of the front crossbeam assembly 10, and the radiator grille guard assembly 30 is used to connect with the longitudinal beam 40.

[0059] In this embodiment, the front crossbeam 11 serves as the main load-bearing member, and its two ends are firmly connected to the longitudinal beam 40 of the vehicle, forming the skeleton at the front end of the vehicle frame, and bearing the impact force and load at the front part of the vehicle during driving. The reinforcing plate sub-assembly 12, including inner and outer reinforcing plates, is tightly combined with the front crossbeam 11 through high-strength bolts, significantly enhancing the bending strength and rigidity of the front crossbeam 11, so that the entire front beam assembly can maintain structural stability and reduce deformation when facing complex road surfaces such as potholes and mud, thereby effectively protecting the front structure of the vehicle. The front tow hook assembly 20 forms a stable connection with the front crossbeam 11 through the reinforcing plate sub-assembly 12, ensuring the structural strength and reliability of the front tow hook in extreme towing environments. The radiator grille guard assembly 30 is located on the lower side of the front crossbeam assembly 10. This setting can achieve comprehensive coverage and protection of the lower part of the vehicle's radiator and the engine oil pan, reducing the risk of damage to the radiator and oil pan caused by external impacts, extending the service life of the vehicle, reducing unplanned downtime, and improving transportation efficiency.

[0060] Applying the technical solution of the present application, the front crossbeam assembly 10 includes a front crossbeam 11 and a reinforcing plate sub-assembly 12. The front crossbeam 11 is connected to the longitudinal beam 40; the front tow hook assembly 20 is connected to the front crossbeam 11 through the reinforcing plate sub-assembly 12; the radiator grille guard assembly 30 is arranged on the lower side of the front crossbeam assembly 10, and the radiator grille guard assembly 30 is used to be connected to the longitudinal beam 40. Such an arrangement improves the strength of the front crossbeam assembly 10 and ensures that the radiator grille guard assembly 30 covers the lower part of the radiator and the engine oil pan, enabling the front end of the vehicle frame to provide stronger anti-dragging ability and protection performance when facing harsh road conditions, and solving the problems of low structural strength and poor anti-impact ability of the front section of the vehicle frame in the prior art.

[0061] Further, the reinforcing plate sub-assembly 12 includes a first reinforcing plate 121 and a second reinforcing plate 122. The front tow hook assembly 20 is connected to the front crossbeam 11 through the first reinforcing plate 121; the second reinforcing plate 122 is connected to the front crossbeam 11, and the first reinforcing plate 121 and the second reinforcing plate 122 are oppositely arranged on both sides of the front crossbeam 11.

[0062] Combined with Figure 2 and Figure 3 As shown, through the first reinforcing plate 121, the front tow hook assembly 20 can be stably installed on the front crossbeam 11, ensuring that when towing a heavy object or the vehicle encounters a frontal impact, the connection point between the front tow hook assembly 20 and the front crossbeam 11 can withstand high loads without failure. The second reinforcing plate 122 forms a direct connection with the front crossbeam 11 to enhance the structural strength and rigidity of the front crossbeam 11. The second reinforcing plate 122 and the first reinforcing plate 121 are oppositely arranged on both sides of the front crossbeam 11. This symmetrical layout can distribute external forces more evenly, reduce the deformation of the front crossbeam 11 when subjected to lateral or longitudinal loads, and ensure the stability of the front-end structure of the vehicle frame. The synergistic effect of the first reinforcing plate 121 and the second reinforcing plate 122 not only increases the structural strength of the front crossbeam 11 but also optimizes the fixing method of the front tow hook assembly 20, forming a more stable front beam assembly. This design ensures that the front end of the vehicle frame can provide stronger load-bearing capacity and protection performance when facing complex working conditions, such as potholed and muddy roads during log transportation, reduces the probability of vehicle repair due to structural damage, and thus improves the operation efficiency and safety of the vehicle.

[0063] Further, the front tow hook assembly 20 includes a pin seat 21 and a pin 22. The pin seat 21 is connected to at least one of the first reinforcing plate 121 and the front crossbeam assembly 10, and the pin seat 21 is provided with a first avoidance space 211; the pin 22 is detachably connected to the pin seat 21.

[0064] Combined with Figure 4As shown, in this embodiment, the latch seat 21 is not only connected to the first reinforcing plate 121, but also directly or indirectly connected to the front crossbeam assembly 10. This design ensures the stable position of the latch seat 21 at the front end of the vehicle frame, enhancing the structural stability of the entire front tow hook assembly 20. In addition, the latch seat 21 is provided with a first avoidance space 211, which serves to provide an avoidance or installation space for the steel wire rope or other towing tools, enabling the steel wire rope to pass through or be fixed on the latch seat 21 smoothly during the towing operation, avoiding jamming or excessive wear of the rope during towing, and improving the efficiency and safety of the towing process. The design of the detachable connection between the latch pin 22 and the latch seat 21 not only facilitates daily maintenance and replacement, but also improves the adaptability and flexibility of the tow hook assembly, providing a more reliable technical guarantee for the use of the log transport vehicle under harsh working conditions.

[0065] Further, the latch seat 21 is provided with a first mounting hole 212. The latch pin 22 includes a pin rod 221, a pin handle 222 and an anti - detachment member 223. The pin rod 221 is inserted into the first mounting hole 212; the pin handle 222 is connected to one end of the pin rod 221, and the geometric center line in the length direction of a part of the pin handle 222 is arranged at an angle with the geometric center line in the length direction of the pin rod 221; the anti - detachment member 223 is detachably connected to the other end of the pin rod 221.

[0066] Combined with Figures 4 to 6 As shown, in this embodiment, the pin rod 221 is the main load - bearing component of the latch pin 22. The selection of its diameter and material ensures sufficient strength and toughness, enabling it to bear high loads without breaking when towing heavy objects. The pin rod 221 is inserted into the first mounting hole 212 of the latch seat 21. This direct insertion connection method not only simplifies the installation process and improves the assembly efficiency, but also ensures the stability of the connection between the pin rod 221 and the latch seat 21 during towing, reducing the safety risks caused by connection loosening. The anti - detachment member 223 is detachably connected to the other end of the pin rod 221 to prevent the pin rod 221 from accidentally coming out of the first mounting hole 212 of the latch seat 21 during towing. This detachable design makes the disassembly and assembly of the anti - detachment member 223 very convenient during daily maintenance or replacement of the tow hook assembly, reducing the maintenance cost and time. At the same time, it is connected to the pin rod 221 through an open - ended pin or other fixing devices, ensuring that the connection between the latch pin 22 and the latch seat 21 will not loosen due to vibration or impact when bearing high - load towing, greatly improving the reliability of the tow hook assembly.

[0067] Furthermore, the pin handle 222 includes a first component segment 2221, a second component segment 2222 and a third component segment 2223, one end of the first component segment 2221 is connected to the pin rod 221; one end of the second component segment 2222 is connected to the other end of the first component segment 2221; one end of the first component segment 2221 is connected to the other end of the second component segment 2222; wherein, the geometric center line of the first component segment 2221 in the length direction is set at an angle to the geometric center line of the pin rod 221 in the length direction, the geometric center line of the first component segment 2221 in the length direction is set at an angle to the geometric center line of the second component segment 2222 in the length direction, and the geometric center line of the second component segment 2222 in the length direction is set at an angle to the geometric center line of the third component segment 2223 in the length direction.

[0068] Combination Figure 6 As shown, in this embodiment, the first component segment 2221 is connected to the pin 221, but its geometric center line is set at a certain angle to the geometric center line of the pin 221. The first component segment 2221, the second component segment 2222 and the third component segment 2223 form a structure with multi-directional tensile and bending resistance, which can convert linear tension into composite force, so that the pin 221 has greater stability and bending resistance when subjected to tension, thereby improving the tensile strength of the entire assembly and reducing the risk of bending or breaking of the pin 221 during high-load towing.

[0069] Furthermore, the geometric center line of the first segment 2221 in the length direction is perpendicular to the geometric center line of the pin 221 in the length direction, the geometric center line of the first segment 2221 in the length direction is perpendicular to the geometric center line of the second segment 2222 in the length direction, and the geometric center line of the second segment 2222 in the length direction is perpendicular to the geometric center line of the third segment 2223 in the length direction.

[0070] Combination Figure 6 As shown, in this embodiment, the vertical section design of the pin handle 222, the first avoidance space 211 of the pin seat 21, the high-strength material of the pin rod 221 and the anti-slip member 223 together constitute a highly reliable and high-efficiency front tow hook system, which enhances the tensile performance, impact resistance and safety and efficiency of the towing hook assembly.

[0071] Furthermore, the latch socket 21 is made of 40Cr. 40Cr has high hardness and strength. Such a setting can withstand the huge stress generated during the high-load towing process, avoiding the fracture or severe wear of the latch socket 21 during the towing operation. Moreover, 40Cr has good toughness, which can effectively absorb the sudden impact load during the towing process, protecting the latch socket 21 from being damaged by impact under complex road conditions. In addition, 40Cr has strong corrosion resistance, which can reduce the rust risk when used in outdoor humid environments and extend the service life of the latch socket 21.

[0072] Furthermore, the pin rod 221 is a solid steel rod. Compared with the hollow structure, the solid steel rod has higher strength and rigidity, can withstand greater tensile force, and reduces the possibility of deformation or fracture under high-load towing. And the solid steel rod is relatively simple to process and form, facilitating production and manufacturing, and helping to reduce the production cost of the components.

[0073] Furthermore, the pin handle 222 is made of steel. Such a setting ensures that the pin handle 222 has sufficient strength and durability. The use of steel ensures that the pin handle 222 is not easily deformed when bearing the towing load. At the same time, steel has good weldability, facilitating the welding connection between the pin handle and the pin rod, and ensuring the overall structural strength and stability of the components.

[0074] Furthermore, the water tank guard plate assembly 30 includes a bottom guard plate 31 and a connecting sub-assembly 32. The bottom guard plate 31 is arranged on the lower side of the front crossbeam assembly 10, and the geometric centerlines in the length direction of at least part of the bottom guard plate 31 are arranged at an angle with the geometric centerlines in the length direction of another part of the bottom guard plate 31; the bottom guard plate 31 is connected to the longitudinal beam 40 through the connecting sub-assembly 32.

[0075] Combined Figure 7 and Figure 8 As shown, in this embodiment, the bottom guard plate 31 is designed to be zigzag, that is, the geometric centerlines in the length direction of part of the bottom guard plate are arranged at an angle with the geometric centerlines in the length direction of another part of the bottom guard plate, so as to completely cover the lower part of the water tank and the engine oil pan from front to back, providing comprehensive protection and effectively preventing the water tank and the oil pan from being directly impacted or scratched under complex road conditions such as muddy depressions and pit bottoms. And the zigzag design of the bottom guard plate 31 helps to improve the air flow at the bottom of the vehicle, reduce the wind resistance during driving, make the stress distribution more uniform, reduce the stress concentration points, and improve the fuel economy and operating efficiency of the vehicle. The use of the connecting sub-assembly 32 makes the connection between the bottom guard plate 31 and the longitudinal beam 40 more stable, and at the same time facilitates the installation and disassembly of the bottom guard plate 31, reducing the maintenance cost and time. Compared with direct welding, the connecting sub-assembly 32 and the bottom guard plate 31 are installed by high-strength bolts. Such an installation method reduces the number of weld points, thereby reducing the risk of corrosion at the weld points and improving the anti-corrosion performance and service life of the water tank guard plate assembly 30.

[0076] Further, the bottom guard plate 31 includes a bottom guard plate body 310 and a reinforcing rib 311, the bottom guard plate body 310 includes a first plate segment 3101, a second plate segment 3102 and a third plate segment 3103, the first plate segment 3101 is connected to the second plate segment 3102, the second plate segment 3102 is connected to the third plate segment 3103, the second plate segment 3102 is connected to the longitudinal beam 40 via a connecting subassembly 32, wherein the geometric center line of the first plate segment 3101 in the length direction is set at an angle to the geometric center line of the second plate segment 3102 in the length direction, and the geometric center line of the second plate segment 3102 in the length direction is set at an angle to the geometric center line of the third plate segment 3103 in the length direction; one end of the reinforcing rib 311 is connected to the bottom guard plate body 310, and the other end of the reinforcing rib 311 extends away from the bottom guard plate body 310, there are multiple reinforcing ribs 311, and the multiple reinforcing ribs 311 are arranged at intervals along the width direction of the bottom guard plate body 310. Figure 8 As shown, in this embodiment, through the multi-section connection of the first plate segment 3101, the second plate segment 3102 and the third plate segment 3103, and the angled design between the plate segments, the bottom guard plate 31 can provide more comprehensive protection from front to back by covering the lower part of the water tank and the engine oil pan. This design ensures that when the vehicle encounters a hard material impact, the important parts can be effectively protected and the risk of damage is reduced. In addition, the multi-section angle design increases the rigidity of the bottom guard plate 31, making it less likely to deform when subjected to impact. Multiple reinforcing ribs 311 are arranged at intervals along the width direction of the bottom guard plate body 310, which can significantly enhance the rigidity and bending strength of the bottom guard plate 31, especially when subjected to lateral impact, it can effectively prevent the bottom guard plate from bending or denting. Not only does it enhance the protection performance, but it also takes into account the optimized distribution of weight, avoiding the bottom guard plate 31 from having a negative impact on the vehicle performance due to local overweight, and improving the vehicle's handling and stability. The multi-section angle design of the bottom guard plate 31 and the layout of the reinforcing ribs 311 work together to form a highly reliable protection system. In practical applications, this design can effectively withstand a towing load of at least 294,000N and impacts under various complex road conditions, ensuring the safety of the water tank and engine oil pan.

[0077] Further, the connecting sub-component 32 includes a first connecting bracket 321, a transition bracket 323, and a second connecting bracket 322. One end of the first connecting bracket 321 is connected to the longitudinal beam 40; one end of the transition bracket 323 is connected to the other end of the first connecting bracket 321, and the other end of the transition bracket 323 is connected to the second plate segment 3102; one end of the second connecting bracket 322 is connected to the second plate segment 3102, and the other end of the second connecting bracket 322 is connected to the longitudinal beam 40; wherein, the geometric centerlines in the length direction of a part of the second connecting bracket 322 are arranged at an angle to the geometric centerlines in the length direction of another part of the second connecting bracket 322.

This design further strengthens the connection between the bottom guard plate 31 and the longitudinal beam 40, improves the stability and strength of the overall structure, and ensures the protection effect under towing loads and complex road conditions. The geometric centerlines in the length direction of a part of the second connecting bracket 322 are arranged at an angle to the geometric centerlines in the length direction of another part of the second connecting bracket 322. This design can be optimized according to the specific contour and spatial layout of the vehicle bottom, improving the tightness and safety of the connection. At the same time, it also helps to disperse and absorb the acting forces, protecting the water tank and the oil pan from damage.

Compared with traditional welding, the use of screw connection reduces the risk of corrosion at the welding points and enhances the anti-corrosion ability of the connection parts. At the same time, the screw connection also provides more convenient installation and disassembly operations, reducing maintenance costs and time.

[0081] Furthermore, the transition bracket 323 includes a first plate body 3231 and a second plate body 3232, the first plate body 3231 is connected to the second plate section 3102, and the first plate body 3231 is provided with a plurality of second mounting portions 3233; one end of the second plate body 3232 is connected to the first plate body 3231, and the other end of the second plate body 3232 is connected to the first connecting bracket 321, the second plate body 3232 is provided with a plurality of second mounting portions 3233, and the second plate body 3232 is provided with a plurality of avoidance portions 3234; wherein the geometric center line of the first plate body 3231 in the width direction is arranged at an angle to the geometric center line of the second plate body 3232 in the width direction.

[0082] Combination Figure 8 and Figure 10 As shown, in this embodiment, the geometric center line of the first plate body 3231 in the width direction is set at an angle to the geometric center line of the second plate body 3232 in the width direction. This design enhances the structural strength and stability of the transition bracket 323 by adding additional support points and changing the force transmission path, so that the bottom guard plate 31 can better disperse the force and reduce deformation when subjected to impact. A plurality of second mounting portions 3233 are provided on the transition bracket 323, which are used in conjunction with the first mounting portion 3211 on the first connecting bracket 321 to achieve a multi-point stable connection, further improving the rigidity and impact resistance of the connection part. A plurality of second mounting portions 3233 are provided on the transition bracket 323, which are used in conjunction with the first mounting portion 3211 on the first connecting bracket 321 to achieve a multi-point stable connection, further improving the rigidity and impact resistance of the connection part. The setting of the first connecting bracket 321 and the transition bracket 323 not only optimizes the connection between the bottom guard plate 31 and the longitudinal beam 40, and improves the strength and stability of the connection part, but also ensures no interference between vehicle components through the design of the avoidance portion 3234 and the second avoidance space 3212, thereby maintaining the normal operation of the vehicle.

[0083] Further, the second connecting bracket 322 includes a first connecting section 3221 and a second connecting section 3222.

[0084] Combined with villain 8 and Figure 11 As shown in the figure, in this embodiment, the first connecting section 3221 is directly connected to the second plate section 3102, and the geometric center line in the length direction of the first connecting section 3221 is arranged at an angle with at least part of the geometric center line in the length direction of the second connecting section 3222. This design can change the direction of force transmission, achieve multi-directional dispersion of force, reduce the force borne by a single connection point, and reduce the risk of damage. The second connecting bracket 322 significantly improves the connection strength and stability between the bottom guard plate 31 and the longitudinal beam 40 through its segmented and angled structure, optimizes the force transmission path, and enhances the protection performance of the water tank guard plate assembly 30 when facing a towing load of at least 294,000 N and complex road conditions. This design not only enhances the protection of key vehicle components, reduces maintenance costs, but also improves the overall performance and economy of the vehicle by improving connection efficiency and optimizing space layout.

[0085] In another embodiment of the present application, a vehicle is further provided, including a front beam assembly, and the front beam assembly is the front beam assembly in the above embodiment.

[0086] Specifically, the front beam assembly includes a front crossbeam assembly 10, a front tow hook assembly 20, and a water tank guard plate assembly 30. The front crossbeam assembly 10 includes a front crossbeam 11 and a reinforcing plate sub-assembly 12. The front crossbeam 11 is used to connect to the longitudinal beam 40 of the vehicle; the front tow hook assembly 20 is connected to the front crossbeam 11 through the reinforcing plate sub-assembly 12; the water tank guard plate assembly 30 is arranged on the lower side of the front crossbeam assembly 10, and the water tank guard plate assembly 30 is used to connect to the longitudinal beam 40.

[0087] In this embodiment, the front crossbeam 11 serves as the main load-bearing member. Its two ends are firmly connected to the longitudinal beams 40 of the vehicle, forming the framework at the front end of the vehicle frame, and bearing the impact force and load at the front part of the vehicle during driving. The reinforcing plate subassembly 12, including inner and outer reinforcing plates, is tightly combined with the front crossbeam 11 through high-strength bolts, significantly enhancing the bending strength and rigidity of the front crossbeam 11. When the entire front beam assembly faces complex road surfaces such as potholes and mud, it can maintain structural stability, reduce deformation, and thus effectively protect the front structure of the vehicle. The front tow hook subassembly 20 is firmly connected to the front crossbeam 11 through the reinforcing plate subassembly 12, ensuring the structural strength and reliability of the front tow hook in extreme towing environments. The radiator grille guard subassembly 30 is located on the lower side of the front crossbeam assembly 10. This setting can achieve comprehensive covering and protection of the lower part of the vehicle's radiator and the engine oil pan, reducing the risk of damage to the radiator and oil pan caused by external impacts, extending the service life of the vehicle, reducing unplanned downtime, and improving transportation efficiency.

[0088] By integrating the innovative designs of the reinforced front crossbeam assembly, front tow hook, and radiator grille guard assembly into the overall structure of the vehicle, the vehicle in this embodiment has achieved significant improvements in terms of safety, load-bearing capacity, maintenance efficiency, and economy, providing a more efficient, safe, and economical transportation solution for the log transportation industry.

Through high-strength materials and optimized structural layout, the bearing capacity and impact resistance of the entire front beam assembly have been significantly improved.

[0091] 2) The front tow hook subassembly 20 is realized through a detachable pin 22 and a pin seat 21. The first avoidance space 211 designed in the pin seat 21 ensures the smooth operation of tools such as wire ropes during towing. The pin 22 is composed of a pin rod 221 and a pin handle 222. The multi-segment angle setting of the pin handle 222 and the use of the anti-disengagement member 223 enhance the towing safety. At the same time, the detachable connection design reduces the maintenance cost and time.

[0092] 3) The radiator grille guard subassembly 30 adopts the design of a folded bottom guard plate 31. The bottom guard plate 31 is composed of a first plate segment 3101, a second plate segment 3102, and a third plate segment 3103. The segments are arranged at an angle to each other, which can effectively disperse and absorb the impact force, protecting the radiator and the engine oil pan from damage. The layout of the reinforcing ribs 311 further improves the rigidity of the bottom guard plate 31.

[0093] 4) The connecting subassembly 32 includes a first connecting bracket 321, a transition bracket 323, and a second connecting bracket 322, and realizes a firm connection between the bottom guard plate 31 and the longitudinal beam 40 through screw connection.

[0094] 5) The pin seat 21 is forged from 40Cr material, having high tensile strength and wear resistance, ensuring the structural stability of the front tow hook assembly 20. The pin rod 221 is a solid steel rod, and the pin handle 222 is made of steel. The selection of these materials and the optimization of the processing technology ensure the high strength and durability of the tow hook assembly.
