[0002] Fenders are essential truck accessories, widely used on a variety of vehicle models. Their primary function is to prevent mud, rain, and lubricating oil from splashing onto the vehicle body, thereby extending the vehicle's service life. Center and rear axle fenders are primarily used to block mud and sand on the center and rear axles of trucks. Their crucial role requires a supporting structure for secure installation.

[0003] Currently, fixed support structures are commonly used in existing technologies. They are simple and easy to install. However, due to their fixed structure, they cannot be adjusted in height, which presents the following problems: Fixed support structures have low strength, and long-term vibration can cause the bent tubes or connecting plates to break, affecting the use of the fender; fixed support structures have a fixed height, making it difficult to adjust the fender height, reducing its effectiveness. Furthermore, these solutions also suffer from weak anti-roll resistance, improper clearances with frame components, and manufacturing limitations due to molding processes.

[0004] Existing fender support structures often fail to adequately consider the clearances between them and other vehicle frame components, such as the upper cover and suspension leaf springs. Improper clearances can cause interference between the fender and these components, impacting overall frame performance and vehicle stability, particularly under conditions of high lateral forces, such as rapid cornering or crosswinds.

[0043] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this 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 layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0044] Combine Figures 1 to 3 As shown, according to a specific embodiment of the present application, a fender device and a vehicle having the same are provided.

[0045] Specifically, the fender assembly comprises a support assembly 1 and a fender assembly. The support assembly 1 includes a rod-shaped support member 11, the ends of which are connected to the longitudinal beam. The fender assembly is connected to the rod-shaped support member 11. The fender assembly is used to block mud and water generated during vehicle movement. The fender assembly can be adjusted to different working positions at different heights by deforming the rod-shaped support member 11 in a predetermined direction and at a predetermined angle.

[0046] The technical solution of the present invention, by deforming the rod-shaped support member 11 in a predetermined direction and angle, not only enhances the structural stability and anti-roll capability, but also enables flexible adjustment of the fender assembly's installation height to meet the needs of different vehicle models and usage scenarios, improving the fender assembly's applicability and vehicle adaptability. This solution addresses the technical issue of the existing fixed support structure's inability to adjust its height.

[0047] Specifically, the rod body portion 100 located between the two ends of the rod-shaped support member 11 is arranged at a distance from the longitudinal beam, wherein the rod-shaped support member 11 is a hollow structure. By designing the rod-shaped support member 11 as a hollow structure, not only the overall weight of the support assembly 1 is reduced, but also its elastic deformation capability is improved. Compared with a solid structure, when the rod-shaped support member 11 is designed as a hollow structure, the stress can be more evenly distributed on the rod wall when the hollow structure is bent, avoiding the concentration of stress in a certain area, thereby reducing material damage and cracking, so that the part can still maintain a high structural integrity after bending. Compared with a solid structure, the hollow structure has better plasticity, and can further realize the deformation of the rod-shaped support member 11 in a preset direction and a preset angle, thereby achieving precise bending at a preset angle.

[0048] Furthermore, the rod-shaped support member 11 includes: a bent section 101, a straight section 121, and a support rod 15. The first end of the bent section 101 is connected to the base 12, and the second end of the bent section 101 extends gradually away from the longitudinal beam along the thickness direction of the longitudinal beam; a bent section 101 is provided at each end of the straight section 121, and the two bent sections 101 are arranged opposite each other; one end of the support rod 15 is connected to the straight section 121, and the other end of the support rod 15 is connected to the fender assembly; wherein, the bent section 101 is operated to deform in a preset direction and a preset angle, so that the straight section 121 and the support rod 15 drive the fender assembly to work positions at different heights. In this solution, the bent section 101 can deform in a preset direction when subjected to an external force, thereby driving the straight section 121 and the support rod 15 to rise or fall as a whole, thereby achieving height adjustment of the fender assembly, allowing the fender assembly to more flexibly adapt to different vehicle heights and road conditions, and improving the effect of shielding mud and water.

[0049] It should be further explained that the bases 12 are welded to both ends of the rod-shaped support members 11. Each base 12 has two connection holes, and the rod-shaped support members 11 are connected to the longitudinal beams through the bases 12. The bases 12 serve as a bridge connecting the rod-shaped support members 11 and the longitudinal beams, evenly transferring the lateral force, impact force, and load borne by the rod-shaped support members 11 to the longitudinal beams of the vehicle.

[0050] Connecting the base to the longitudinal beam ensures smooth force transmission, avoiding localized stress concentration that could occur when rod-shaped support members 11 directly contact the longitudinal beam, thereby reducing the risk of structural fatigue and damage. Under high loads and adverse road conditions, this reinforcement prevents excessive deformation of rod-shaped support members 11, maintaining their structural integrity and thus ensuring the stability and safety of support assembly 1.

[0051] like Figure 1 As shown, the straight segment 121 forms the main portion of the rod-shaped support member 11. Located between the two bent segments 101, it serves as a connection and force transmission mechanism. A bent segment 101 is positioned at each end of the straight segment 121. The two bent segments 101 face each other, forming a stable "V" or "Λ"-shaped structure. This design ensures smooth movement of the straight segment 121 when the angles of the bent segments 101 are changed, allowing the support rod 15 and fender assembly to be adjusted to different working heights.

[0052] Optionally, one end of the support rod 15 is connected to the straight section 121, and the other end of the support rod 15 is connected to the fender assembly. The relative position of the support rod 15 and the straight section 121 remains unchanged, but the angle between the support rod 15 and the longitudinal beam and the base 12 will change as the straight section 121 moves, thereby realizing height adjustment of the fender assembly and maintaining the stability of the fender assembly installation and the integrity of the frame structure.

[0053] It should be further explained that the support assembly also 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 support rod 15. One end of the support rod 15 is connected to the straight segment 121, and the other end of the support rod 15 extends away from the straight segment 121 and passes through the plurality of support plates 16. The support plates 16 can further enhance the structural strength, rigidity and stability of the entire support assembly.

[0054] There are multiple connecting seats 17, and the multiple connecting seats 17 are arranged at intervals along the length direction of the support rod 15. The connecting seats 17 are arranged below the support plate 16. The side of the connecting seat 17 away from the fender assembly is connected to the two support plates 16, and the other side of the connecting seat 17 is connected to the fender assembly. The connecting seat 17 is fixedly connected to the fender assembly by bolts, rivets or other fasteners, and the support rod 15 is connected to the fender assembly through the connecting seat 17.

[0055] In this embodiment, the connecting seat 17 is configured as a U-shaped plate structure. The design of the U-shaped plate structure provides more contact area, forming a tight fit with the connecting surface of the fender assembly not only in the plane direction but also in the height direction. 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.

[0056] Furthermore, at least one bending segment 101 includes: a first segment 111, a second segment 112, a third segment 113, and a fourth segment 114. The first end of the first segment 111 is connected to the base 12, and the second end of the first segment 111 extends gradually away from the longitudinal beam along the thickness direction of the longitudinal beam; the first end of the second segment 112 is connected to the second end of the first segment 111 at a first angle α, and the second end of the second segment 112 gradually extends toward the side where the other bending segment 101 is located; the first end of the third segment 113 is connected to the second end of the second segment 112, and the second end of the third segment 113 gradually extends toward the side where the other bending segment 101 is located; the first end of the fourth segment 114 is connected to the second end of the third segment 113, and the second end of the fourth segment 114 is connected to the end of the straight segment 121 at a second angle β, with the first angle α and the second angle β both being located on the side of the bending segment 101 facing the longitudinal beam. This solution achieves more precise deformation control and fender assembly height adjustment through the multi-segment structure of the bending section 101. By adjusting the connection angles between the first, second, third, and fourth segments 111, 112, 113, and 114, namely the first angle α and the second angle β, the fender assembly's rise or fall can be controlled. This allows for a wider adjustment range and higher precision, allowing the fender assembly to better adapt to various vehicles and road conditions.

[0057] like Figure 1 As shown, the first end of the first segment 111 is directly connected to the base 12, which is then connected to the longitudinal beam via the base. The connection between the first segment 111 and the longitudinal beam forms the base of the entire support assembly 1, ensuring the stability of the bending segment 101 during adjustment. The second end of the first segment 111 extends gradually away from the longitudinal beam along the thickness direction of the longitudinal beam. This design allows the bending segment 101 to initially have a certain degree of freedom, reducing direct contact and friction with the longitudinal beam, and preventing damage to the longitudinal beam or the bending segment 101 itself during adjustment.

[0058] Optionally, the first end of the second segment 112 is connected to the second end of the first segment 111, forming a first angle α. By varying the magnitude of this first angle α, the overall position of the bent segment 101 can be adjusted, thereby affecting the height of the straight segment 121 and the fender assembly. The second end of the second segment 112 gradually extends toward the side where the other bent segment 101 is located. This design helps maintain an appropriate distance between the bent segment 101 and the longitudinal beam, preventing interference with other structures during adjustment. It also facilitates force transmission and balance.

[0059] Optionally, the first end of the third segment 113 continues to connect to the second end of the second segment 112, with the second end also gradually extending toward the side where the other bent segment 101 is located, focusing more on the connection and transition functions. The provision of the third segment 113 further strengthens the structural strength of the bent segment 101, ensuring that the bent segment 101 can withstand sufficient loads while maintaining the accuracy of its shape and position at different angles.

[0060] Optionally, the first end of the fourth segment 114 is connected to the second end of the third segment 113, while the second end is connected to the end of the straight segment 121, forming a second angle β. The second angle β is located opposite the first angle α, but is also located on the side of the bent segment 101 facing the longitudinal beam. The fourth segment 114 serves as a bridge connecting the bent segment 101 and the straight segment 121. By adjusting the second angle β, the relative position of the straight segment 121 and the base 12 can be changed, thereby causing the fender assembly to rise or fall, achieving height adjustment.

[0061] Specifically, the first angle α ranges from 100° to 140°, the second angle β ranges from 130° to 170°, and the sum of the first and second angles α and β is γ1, where γ1 ranges from 265° to 275°. By precisely setting the ranges of the first and second angles α and β, the appropriate distance between the fender assembly and other frame components is ensured, thereby enhancing the installation and use flexibility of the fender assembly without affecting the overall structure and function of the frame.

[0062] The suspension leaf spring is arranged between the fender assembly and the longitudinal beam. The suspension leaf spring is located below the rod-shaped support member 11. The second angle β ranges from 130° to 170°. The setting of the β angle ensures the height adjustment capability of the fender assembly in the vertical direction. At the same time, the larger β angle can also provide sufficient space between the fender assembly and the suspension leaf spring to avoid interference when the vehicle load changes, thereby maintaining the normal operation of the suspension system.

[0063] In this embodiment, upper covers are respectively installed on both sides of the fender assembly, and the support assembly 1 is located in the middle area of ​​the upper covers on both sides. The range of the first angle α is set to 100°~140°. When the angle α is within this range, the connection between the first end of the bending section 101 and the base 12 will maintain a relatively open angle, which helps to ensure that the fender assembly has sufficient space to avoid contact with the upper cover when the vehicle moves laterally or encounters a lateral impact, thereby reducing damage caused by the collision.

[0064] In this embodiment, the sum of the first and second angles α and β, γ1, is set to 270°. This ensures that the rod-shaped support member 11 maintains good toughness under lateral forces, preventing permanent deformation or fracture. This design can partially absorb lateral forces when the vehicle rolls, reducing the impact of the roll on the fender assembly. Furthermore, the plastic deformation of the bent section 101 distributes the force throughout the support structure, preventing structural damage caused by concentrated force at a single point.

[0065] By controlling the range of the first angle α and the second angle β, and keeping their sum γ1 within a specific range, the installation and use flexibility of the fender assembly is optimized, so that the fender assembly can maintain a reasonable gap with the upper cover and the suspension leaf spring in any working position, thereby avoiding wear that may be caused by direct contact and ensuring that the fender assembly has sufficient movement space under the action of lateral force, reducing unnecessary vibration and impact, thereby improving the stability and anti-roll performance of the fender assembly when the vehicle is driving.

[0066] Specifically, the length of the third segment 113 is greater than or equal to 80 mm. In this embodiment, a length S of the third segment 113 that is too small during bending may result in excessive concentration of material at the bend, creating high-stress areas and potentially causing cracks or breakage during the bending process or after long-term use. A length S of no less than 80 mm ensures that the bent tube can achieve the desired bending angle during both hot and cold bending processes while maintaining shape stability and dimensional accuracy.

[0067] By setting the length of the third segment 113 to be greater than or equal to 80 mm, the process molding requirements are met while ensuring the structural stability and deformation range of the fender assembly when adjusting the height.

[0068] Furthermore, a third angle γ2 is defined between the longitudinal contour of the second segment 112 and the horizontal plane, and the third angle γ2 ranges from 0° to 15°. By setting the third angle γ2 between the second segment 112 and the horizontal plane, the shielding effect of the fender assembly and its mechanical properties during deformation are optimized, ensuring that the fender assembly effectively shields mud and water at various operating heights.

[0069] like Figure 3 As shown, the setting of the third angle γ2 gives the second component segment 112 a small but critical tilt angle in the longitudinal direction. The setting of the third angle γ2 can optimize the force transmission path. During vehicle driving, especially when encountering lateral forces or bumpy roads, by appropriately setting the angle γ2, the force can be transmitted along the tilt direction of the second component segment 112, reducing the possibility of direct force, thereby reducing stress concentration in the second component segment 112 and the entire support structure, and improving its fatigue and damage resistance. The range of the third angle γ2 (0° to 15°) can further support maintaining a reasonable gap between the fender assembly and the upper cover plate and suspension leaf spring.

[0070] Specifically, one end of the support rod 15 is connected to the straight section 121 via the transition plate 13. The transition plate 13 is provided with a positioning structure, through which the support rod 15 is connected to the transition plate 13. The positioning structure is height-adjustable, and by adjusting the height of the positioning structure, the mudguard assembly can be positioned at different operating heights. The positioning structure on the transition plate 13 allows for fine-tuning of the mudguard assembly's height, precisely controlling its final installation height and ensuring that it effectively shields against mud and water at various operating heights.

[0071] The third angle γ2 allows the fender assembly to better adapt to changing road conditions during dynamic driving. For example, when the vehicle traverses uneven roads, the angle γ2 allows the fender assembly to have a certain degree of vertical flexibility, reducing direct impact on the support assembly 1 and improving the durability and stability of the entire device.

[0072] It should be further explained that support assembly 1 also includes reinforcement plates 14, which are disposed on either side of transition plate 13. Reinforcement plates 14 are welded to straight segment 121 and transition plate 13. This welding provides greater connection strength and rigidity. Reinforcement plates 14 provide additional support points, distributing and absorbing external forces, thereby preventing excessive deformation or damage to support assembly 1 when subjected to stress.

[0073] Furthermore, the positioning structure includes an arc segment 131, the opening of which extends downward along the height direction of the transition plate 13. The diameter of the arc segment 131 corresponds to the outer diameter of the support rod 15; and a vertical segment 132, each provided with an arc segment 131 at each end of the vertical segment 132. The two arc segments 131 are arranged opposite each other, the width of the vertical segments 132 corresponds to the outer diameter of the support rod 15, and the height of the vertical segments 132 is adjustable. By adjusting the height of the vertical segments 132, the fender assembly can be adjusted to different working positions at different heights, wherein the maximum height difference between different working positions is H, and the range of H is 0 to 45 mm. Through the coordinated action of the arc segments 131 and the vertical segments 132, the positioning structure not only achieves precise control of the height of the fender assembly, but also greatly enhances the vehicle's serviceability and safety in complex operating conditions.

[0074] like Figure 2 As shown, arc segment 131 is designed primarily to form a fit with the outer edge of support rod 15, thereby ensuring that support rod 15 can be stably embedded in the positioning structure when the fender assembly is positioned at different heights. The opening of arc segment 131 extends downward along the height of transition plate 13. This design allows for smoother vertical movement of support rod 15, reducing resistance and wear during movement. The diameter of arc segment 131 corresponds exactly to the outer diameter of support rod 15, ensuring a tight fit between support rod 15 and the positioning structure, improving the stability and reliability of the entire support system.

[0075] The vertical section 132 is the adjustable portion of the positioning structure. It features an arc segment 131 at each end. These two arc segments 131 are positioned opposite each other, forming a C- or U-shaped positioning slot. The width of the vertical section 132 corresponds exactly to the outer diameter of the support rod 15, ensuring stable lateral positioning of the support rod 15, preventing lateral movement or shaking and guaranteeing the stability of the fender assembly during high-load transport scenarios.

[0076] The height of the vertical section 132 can be adjusted. By adjusting the height of the vertical section 132, the entire support rod 15 and the connected fender assembly can be driven to rise or fall, thereby realizing rapid switching between different working positions. The maximum height difference H between different working positions (ranging from 0 to 45 mm) provides a sufficient adjustment range to adapt to various road conditions and transportation needs.

[0077] Different vehicle models and tire sizes require different installation heights for the fender assembly. The height adjustability of the vertical section 132 allows the same fender assembly to accommodate a variety of different vehicle models or tire sizes, improving the versatility and cost-effectiveness of the design.

[0078] In complex road conditions, such as muddy, icy, or snowy roads, the height and position of the fender assembly may need to be adjusted immediately. The height adjustability of the positioning structure allows for quick adjustment of the fender assembly's position based on real-time road conditions, improving vehicle safety and passability.

[0079] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0080] 1. By introducing an adjustable bending section and transition plate design, this solution achieves flexible adjustment of the fender assembly's installation height while maintaining a reasonable gap between the upper cover and the suspension leaf spring. This enhances the fender assembly's adaptability and stability, avoids structural damage caused by vibration, and improves the frame's overall anti-roll capability.

[0081] 2. By optimizing the angle settings of the first angle α, the second angle β, and the third angle γ of the bending section (a is between 100° and 140°, b is between 130° and 170°, and c is between 0° and 15°) and the design of the length dimension s of the third component segment being greater than or equal to 80 mm, not only the installation height requirements of different fender assemblies are met, but also sufficient strength and durability of the support assembly are ensured.

[0082] 3. Through the height-adjustable design of the vertical section of the positioning structure (the maximum height difference H between different working positions is 0 to 45 mm), this solution can not only adapt to different types of wheels and changes in vehicle size, but also flexibly adjust the position of the fender under complex road conditions, effectively preventing the splashing of mud, sand and rainwater, protecting the safety of vehicles and pedestrians, while reducing vehicle maintenance costs and improving transportation efficiency.

[0083] The above embodiments can 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, which is the fender device of any one of the above embodiments.

[0084] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures.
