[0039] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0040] Combination Figures 1 to 8 As shown, according to a specific embodiment of the present application, a fender device and a frame for a vehicle and a vehicle having the same are provided.

[0041] Specifically, Figure 1 As shown, the fender device includes a support assembly 1 and a fender assembly 2, the support assembly 1 includes a rod-shaped support member 11, both ends of the rod-shaped support member 11 are connected to the longitudinal beam 6, and the rod body portion 100 located between the two ends of the rod-shaped support member 11 is set at a distance from the longitudinal beam 6; the fender assembly 2 is connected to the rod-shaped support member 11, and the fender assembly 2 is used to shield the mud and water generated during the movement of the vehicle.

[0042] By applying the technical solution of the present invention, the two ends of the support assembly 1 are connected to the longitudinal beam 6 of the vehicle to form a stable support point. The fender assembly 2 is connected to the longitudinal beam 6 through the rod-shaped support member 11, which ensures the firm fixation between the fender assembly 2 and the longitudinal beam, enhances the overall lateral stability of the vehicle, and maintains stability even under complex road conditions. The design of maintaining a certain distance between the rod body 100 and the longitudinal beam 6 can effectively absorb and buffer road impact, reduce the impact of the impact force on the fender device and the frame, extend the service life of the fender assembly, and ensure the durability of its protective effect. The present application solves the technical problem of the weak anti-roll capability of the fender support structure of the center and rear axle in the prior art.

[0043] It should be further explained that the support assembly 1 is arranged above the fender assembly 2, and the two ends of the rod-shaped support member 11 can be fixedly connected to the longitudinal beam 6 by bolts or welding, which can further ensure the firmness of the connection between the support assembly 1 and the longitudinal beam 6.

[0044] Specifically, the rod-shaped support member 11 is a hollow tubular structure. The rod-shaped support member 11 is set as a hollow structure, which can significantly reduce the weight of the support assembly 1 while ensuring sufficient strength and rigidity. The material of the rod-shaped support member 11 is selected from high-strength steel or aluminum alloy to ensure that it has sufficient strength while being lightweight. The tube diameter and wall thickness are designed according to the actual load-bearing requirements and impact resistance requirements.

[0045] It should be further explained that the support assembly 1 also includes a base 12, which is welded to the two ends of the rod-shaped support member 11. Each base 12 is provided with two connection holes, and the rod-shaped support member 11 is connected to the longitudinal beam through the base 12. The base 12 serves as a bridge connecting the rod-shaped support member 11 and the longitudinal beam, and uniformly transfers the lateral force, impact force and load borne by the rod-shaped support member 11 to the longitudinal beam of the vehicle. By connecting the base with the longitudinal beam, it is possible to ensure smooth transmission of force and avoid local stress concentration that may be generated when the rod-shaped support member 11 directly contacts the longitudinal beam, thereby reducing the risk of structural fatigue and damage. Under high loads and harsh road conditions, this reinforcement measure can prevent the rod-shaped support member 11 from excessive deformation, maintain its structural integrity, and thus ensure the stability and safety of the support assembly 1.

[0046] like Figure 2 As shown, the support assembly 1 further includes a transition plate 13 and a connecting rod 15. The transition plate 13 is connected to the middle portion of the rod-shaped support member 11; one end of the connecting rod 15 is connected to the transition plate 13, and the other end of the connecting rod 15 is extended away from the transition plate 13, and the fender assembly 2 is connected to the connecting rod 15. The arrangement of the transition plate 13 and the connecting rod 15 optimizes the structure of the support assembly 1 and improves its overall strength and stability.

[0047] Optionally, the connecting rod 15 and the transition plate 13 may be connected by bolts, rivets or welding.

[0048] Specifically, the transition plate is generally made of a thicker metal plate, and the shape can be a flat plate, a U-shaped plate or other structures. In this embodiment, the transition plate adopts a U-shaped structure, and one side of the transition plate 13 is fixed to the middle of the rod-shaped support member 11 by welding or bolting. The transition plate 13 is located in the middle of the rod-shaped support member 11 to ensure uniform distribution of force, avoid eccentric loading of the support assembly 1, and reduce the risk of structural distortion and deformation. Through the connection between the transition plate 13 and the rod-shaped support member 11, the load-bearing capacity and impact resistance of the entire support assembly are improved.

[0049] Furthermore, the support assembly 1 further includes a reinforcing plate 14, which is disposed on both sides of the transition plate 13, and is welded to the rod-shaped support member 11 and the transition plate 13, and is fixed by welding to provide greater connection strength and rigidity. The reinforcing plate 14 can provide additional support points, disperse and absorb external forces, and prevent the support assembly from being excessively deformed or damaged when subjected to force.

[0050] Furthermore, the support assembly 1 further includes a connection seat 17, and there are a plurality of connection seats 17, and the plurality of connection seats 17 are arranged at intervals along the length direction of the connecting rod 15, and the fender assembly 2 is connected to the connecting rod 15 through the connection seat 17. The arrangement of the plurality of connection seats 17 enables the load borne by the fender assembly 2 to be evenly distributed along the length direction of the connecting rod 15, rather than being concentrated on one point, thereby reducing the stress borne by a single connection point and avoiding connection failure or material fatigue caused by local overload.

[0051] Optionally, the connection seat 17 is fixedly connected to the fender assembly 2 by bolts, rivets or other fasteners, which simplifies the assembly process. In this embodiment, the connection seat 17 is set as a U-shaped plate structure. The design of the U-shaped plate structure provides more contact area, not only in the plane direction, but also in the height direction to form a tight fit with the connection surface of the fender assembly 2. The U-shaped structure can provide support from multiple directions, thereby enhancing the firmness of the connection and improving the overall stability between the fender device and the support assembly.

[0052] In this embodiment, the support assembly 1 includes a support plate 16, and a plurality of support plates 16 are provided. The plurality of support plates 16 are arranged at intervals along the length direction of the connecting rod 15, one end of the connecting rod 15 is connected to the transition plate, and the other end of the connecting rod 15 is extended away from the transition plate 13 and passes through the support plate 16, and the support plate 16 is arranged above the connecting seat 17, and every two support plates 16 are connected to a side of the connecting seat 17 away from the fender assembly 2, and the connecting seat 17 is connected to the connecting rod 15 through the support plate 16. The support plate 16 can further improve the structural strength, rigidity, and stability of the entire support assembly.

[0053] Specifically, the rod body 100 includes: a first component section 111, a second component section 112 and a third component section 113. The first end of the first component section 111 is connected to the longitudinal beam 6, and the second end of the first component section 111 is gradually extended away from the longitudinal beam 6 along the thickness direction of the longitudinal beam 6; the first end of the second component section 112 is connected to the second end of the first component section 111 and is arranged at a first angle, and the second end of the second component section 112 is extended along the length direction of the longitudinal beam 6; the first end of the third component section 113 is connected to the longitudinal beam 6, and the second end of the third component section 113 is gradually extended away from the longitudinal beam 6 along the thickness direction of the longitudinal beam 6 and connected to the second end of the second component section 112, and the second end of the third component section 113 is arranged at a second angle with the second end of the second component section 112; wherein the first component section 111, the second component section 112 and the third component section 113 and the longitudinal beam 6 form a hollow area 110. The multi-section design of the rod body 100 takes into account both the dispersion and centralized transmission of force, ensuring that the force transmitted downward from the fender assembly can be more evenly distributed to the longitudinal beam 6, thereby reducing the local stress on the longitudinal beam 6 and reducing the risk of structural fatigue and damage.

[0054] Optionally, the first end of the first component section 111 is directly connected to the longitudinal beam 6 of the vehicle, and is designed to gradually extend outward from the longitudinal beam 6 in the thickness direction. This design helps to disperse and transmit the force transmitted downward from the fender device, and avoid excessive force on the longitudinal beam 6. At the same time, the connection between the first component section 111 and the longitudinal beam 6 is usually strengthened to ensure the reliability of the connection and the stability of the structure.

[0055] The first end of the second component segment 112 forms a first angle with the second end of the first component segment 111, and the second end of the second component segment 112 extends along the length direction of the longitudinal beam 6. This inclined design helps to support the weight of the fender device and provide lateral stability during vehicle driving to resist impact and vibration from the road surface.

[0056] The first assembly segment 111, the second assembly segment 112 and the third assembly segment 113 form a more stable triangular structure, which significantly improves the rigidity of the entire support assembly and improves its ability to resist deformation. The hollow area surrounded by the first assembly segment 111, the second assembly segment 112 and the third assembly segment 113 and the longitudinal beam 6 is designed to reduce the weight of the support assembly without sacrificing the strength and stability of the structure. The hollow area can also be used as an installation space for other components to improve the design flexibility and integration of the vehicle.

[0057] According to another specific embodiment of the present application, a vehicle frame is provided, including a fender device, a crossbeam assembly 5 and a longitudinal beam 6, wherein the longitudinal beam 6 is connected to both ends of the crossbeam assembly 5 via a connecting component, and the fender device is the fender device of any one of the above embodiments.

[0058] Specifically, the longitudinal beam 6 is configured as a trough-type structure. In the present embodiment, two longitudinal beams 6 are provided, and the two longitudinal beams 6 are arranged at intervals; the crossbeam assembly 5 is arranged between the longitudinal beams 6 on both sides, and the crossbeam assembly 5 is connected to the longitudinal beams through a connecting component.

[0059] Specifically, the connection assembly includes an upper connection member 52 and a lower connection member 53 that are symmetrically arranged. At least one of the upper connection member 52 and the lower connection member 53 is provided with a transverse plate 500 and a vertical plate 501. The transverse plate 500 is connected to the crossbeam assembly 5, and the vertical plate 501 is connected to the longitudinal beam 6. The transverse plate 500 is extended along the length direction of the longitudinal beam 6, and the vertical plate 501 is extended along the height direction of the longitudinal beam 6. When the vehicle travels on an uneven road or is subjected to a lateral force, the transverse plate 500 and the vertical plate 501 can evenly transfer the force to the crossbeam assembly 5 and the longitudinal beam 6, avoiding local overload and reducing the risk of structural damage.

[0060] Optionally, in this embodiment, the upper connecting member 52 and the lower connecting member 53 are set to be L-shaped, and the upper connecting member 52 and the lower connecting member are both composed of two parts: a horizontal plate 500 and a vertical plate 501. The horizontal plate 500 of the upper connecting member 52 is located above the top of the crossbeam assembly 5, and the horizontal plate 500 of the lower connecting member 53 is located below the bottom of the crossbeam assembly 5. The vertical plates of the upper connecting member and the lower connecting member are both connected to the longitudinal beam 6, and the upper connecting member and the lower connecting member are spaced apart.

[0061] The addition of the cross plate 500 and the vertical plate 501 forms an additional strong frame by connecting with the cross beam assembly 5 and the longitudinal beam 6. This frame structure can significantly enhance the lateral and longitudinal rigidity of the frame and improve the vehicle's ability to resist deformation. The design of the cross plate 500 and the vertical plate 501 optimizes the force transmission path. The cross plate 500 can transmit the lateral force to the cross beam assembly 5 more directly, while the vertical plate 501 is responsible for transmitting the vertical force to the longitudinal beam 6. This design ensures that the force transmission is more efficient and controllable, reducing unnecessary stress concentration and structural fatigue.

[0062] like Figure 8 As shown, the length of the cross plate 500 of the upper connecting member 52 and the lower connecting member 53 is greater than 1700 mm. By increasing the length of the cross plate of the upper connecting member 52 and the lower connecting member 53, the connection strength and stability between the cross beam assembly 5 and the longitudinal beam 6 can be improved, thereby significantly increasing the anti-rolling ability of the frame and improving the safety and stability of the heavy-load tractor.

[0063] Furthermore, the connection assembly includes a pad 54, which is disposed between the cross beam assembly 5 and the lower connection member 53, and is respectively connected to the cross beam body 51 and the lower connection member 53. The pad 54 enhances the connection stability between the cross beam assembly 5 and the lower connection member 53, optimizes the force transmission path, and improves the rigidity and durability of the entire support structure.

[0064] like Figure 8 As shown, the pad 54 is usually made of high-strength materials, such as high-strength steel or alloy, to ensure its sufficient load-bearing capacity and durability. The pad 54 is designed as a flat structure with sufficient surface area to contact the crossbeam body 51 and the lower connecting piece 53 to enhance the stability of the connection. Connection holes are provided on both sides of the pad 54 for fixing with the crossbeam body 51 and the lower connecting piece 53 by bolts, rivets or other fasteners to ensure the reliability of the connection. The addition of the pad 54 increases the contact points between the crossbeam body 51 and the lower connecting piece 53, which helps to improve the structural rigidity of the entire crossbeam assembly 5. Under the action of the lateral force of the vehicle, the deformation of the crossbeam assembly can be reduced, the stability of the vehicle can be maintained, and the risk of rollover can be reduced.

[0065] Furthermore, the frame also includes: a bottom plate connector 4 and a bottom plate 3, the bottom plate connector 4 is arranged above the longitudinal beam 6, and the bottom plate connector 4 is connected to the longitudinal beam 6; the bottom plate 3 is arranged above the cross beam assembly 5, and the two ends of the bottom plate 3 are respectively connected to the bottom plate connectors 4 on both sides.

[0066] like Figure 4 As shown, the bottom plate 3 includes: a second connection hole 31, a third connection hole 32 and a weight-reducing hole 33. A plurality of second connection holes 31 are arranged along the periphery of the bottom plate 3; the second connection holes 31 are used to connect the bottom plate 3 with the bottom plate connector 4. Through the arrangement of the plurality of second connection holes, the bottom plate 3 can be firmly fixed on the vehicle frame, ensuring that the bottom plate 3 will not be displaced or loosened under various driving conditions.

[0067] The third connection holes 32 are arranged at both ends of the bottom plate 3. There are a plurality of third connection holes 32. The third connection holes 32 are arranged as countersunk holes. The bottom plate 3 is connected to the saddle through the third connection holes 32. The third connection holes 32 adopt a countersunk hole structure. The purpose of this design is to prevent the head of the connection bolt from protruding when the saddle is installed, and / or from interfering with the bottom plate connector 4, thereby ensuring the stability of the saddle and the normal function of the bottom plate connector 4. At the same time, the countersunk hole structure also helps to reduce stress concentration at the bolt connection and improve the reliability of the connection.

[0068] The weight-reducing holes 33 are arranged in the middle area of ​​the bottom plate 3. Holes are opened in non-critical stress-bearing areas to effectively remove excess material, reduce the material usage of the bottom plate 3, and reduce the overall weight of the frame. The arrangement of the weight-reducing holes 33 helps to improve the thermal expansion performance of the bottom plate 3, reduce structural deformation caused by temperature changes, and extend the service life of the bottom plate 3 and the entire frame.

[0069] Specifically, Figure 7 As shown, the bottom plate connecting member 4 includes: a second connecting member 41 and a third connecting member 42. One side of the second connecting member 41 is connected to the longitudinal beam 6, and the top of the second connecting member 41 is connected to the bottom plate 3; a third connecting member 42, one side of the third connecting member 42 is connected to the longitudinal beam 6, and the third connecting member 42 and the second connecting member 41 are connected to the bottom plate 3 through a fourth connecting member 45. The third connecting member 42 and the second connecting member 41 are arranged at intervals along the length direction of the longitudinal beam 6, so that an escape space 47 for escaping the leaf spring is formed between the end of the second connecting member 41 and the end of the third connecting member 42.

[0070] In this embodiment, the second connecting member 41 and the third connecting member 42 are both designed as L-shaped structures, one side of which is fixed to the longitudinal beam 6 by welding or bolting, and the top of the other side is used to connect the bottom plate 3. The multi-point connection design of the second connecting member 41 and the third connecting member 42 significantly enhances the connection strength and rigidity between the bottom plate 3 and the frame, improves the stability of the vehicle under various working conditions, and reduces the risk of structural deformation and damage.

[0071] The avoidance space 47 is formed between the second connecting member 41 and the third connecting member 42 to solve the problem of interference with the leaf spring (a part of the vehicle suspension system) when the bottom plate 3 is installed. By accurately designing the spacing between the second connecting member 41 and the third connecting member 42, the normal operation of the leaf spring during the vehicle driving process can be ensured, and the bottom plate 3 is prevented from hindering the movement of the leaf spring, thereby maintaining the suspension performance of the vehicle.

[0072] Specifically, Figure 6 As shown, the bottom plate connector 4 further includes: a first reinforcement 43 and a second reinforcement 44. The first reinforcement 43 is arranged on a side of the second connector 41 away from the fourth connector 45, and the first reinforcement 43 is connected to the second connector 41; the second reinforcement 44 is arranged on a side of the third connector 42 away from the fourth connector 45, and the second reinforcement 44 is connected to the third connector 42, and the first reinforcement 43 and the second reinforcement 44 are arranged at intervals along the length direction of the longitudinal beam 6. The arrangement of the first reinforcement 43 and the second reinforcement 44 further improves the lateral stiffness of the frame, reduces the deformation of the vehicle under the action of lateral force, prolongs the service life of the frame, and improves the economy of the vehicle.

[0073] In this embodiment, the height dimension of the first reinforcement member 43 is smaller than that of the second connection member 41, and the height dimension of the second reinforcement member 44 is smaller than that of the third connection member 42. The addition of the first reinforcement member 43 and the second reinforcement member 44 significantly enhances the structural strength of the second connection member 41 and the third connection member 42, improves the overall bearing capacity and anti-deformation capacity of the bottom plate connection member 4, and ensures the stability of the vehicle under high load and bad road conditions. The first reinforcement member 43 and the second reinforcement member 44 are usually made of high-strength materials, such as steel or aluminum alloy, to further ensure that the bottom plate connection member has sufficient strength.

[0074] It should be further explained that the fourth connecting member 45 is configured as a groove structure, the opening of the fourth connecting member 45 is configured away from the second connecting member 41, the side of the fourth connecting member 45 is connected to the second connecting member 41 and the third connecting member 42, and the top of the fourth connecting member 45 and the bottom of the fourth connecting member 45 are connected to the longitudinal beam 6. The bottom plate connecting member 4 also includes a third reinforcement member 46, which is located inside the fourth connecting member 45, and the third reinforcement member 46 is welded to the fourth connecting member 45, which can further enhance the structural strength and rigidity of the fourth connecting member 45.

[0075] like Figure 3 As shown, the fender assembly 2 includes: a fender body 21 and a clamping bracket 22. The fender body 21 is integrally formed. In this embodiment, the fender body 21 is an injection-molded plastic part, and crisscross reinforcement ribs are arranged inside. The fender body of this design is not only light in weight, but also has high structural strength, can effectively resist various impacts and vibrations, and prolongs its service life. The integral molding process can also ensure seamless connection between the inside and outside of the fender, and improve its sealing and water resistance.

[0076] The clamping bracket 22 is arranged outside the fender body 21 and is made of high-strength materials such as aluminum profiles. A through hole is provided on the clamping bracket 22 for fixing with the first connecting hole 23 on the fender body 21 through a fastener such as a bolt assembly. A threaded hole is provided on the top of the clamping bracket 22, which corresponds to the first connecting hole 23 on the top of the fender body 21 one by one, forming a stable connection structure. This design of the clamping bracket can provide additional support and fixation between the fender body 21 and the connecting seat 17 of the frame, thereby enhancing the structural rigidity of the entire fender device.

[0077] In this embodiment, the clamping bracket 22 is connected to the fender body 21 by bolts. This detachable design is not only convenient for daily maintenance, such as cleaning or replacement, but also allows the position of the fender to be adjusted when necessary to adapt to different vehicle configurations or usage environments. Compared with traditional metal fenders, the fender body 21 made of injection molding and the clamping bracket 22 made of aluminum profiles can significantly reduce the weight of the vehicle. At the same time, the selection of these materials and manufacturing processes can also reduce production costs and improve economic benefits. The plastic material of the fender body 21 and the aluminum profile of the clamping bracket 22 have good corrosion resistance and can adapt to various harsh environments, such as rainy and snowy weather, salt spray corrosion, etc., to extend the service life of the fender.

[0078] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0079] 1. By optimizing the design of the fender support assembly and the frame connection, including the use of multi-section rod-shaped supports, injection-molded fender bodies, and the provision of reinforcing ribs inside the fender bodies, the entire system has significantly enhanced its lateral and longitudinal structural strength and impact resistance. This design ensures the stability and safety of the vehicle under heavy loads, reduces the risk of structural deformation and damage, and enhances the overall lateral stability of the vehicle.

[0080] 2. By increasing the X-span of the support assembly and optimizing the length of the upper and lower connectors, this solution significantly enhances the anti-roll capability of the frame and improves the safety and handling of the vehicle in heavy-load transportation scenarios. At the same time, the avoidance space design of the bottom plate connector ensures compatibility with the leaf spring, maintains the normal operation of the suspension system, and improves ride comfort and vehicle performance.

[0081] 3. By setting up hollow rod-shaped support members and weight-reducing holes on the bottom plate, the vehicle's own weight is reduced without affecting the stability and strength of the overall structure, thereby improving fuel efficiency and load-bearing capacity.

[0082] The above embodiments may also be used in the field of equipment technology. That is, according to another aspect of the present invention, a vehicle is provided, comprising a fender device, and the fender device is the fender device of any one of the above embodiments.
