[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[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 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.

[0044] Combination 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 device comprises: a support assembly 1 and a fender assembly. The support assembly 1 comprises a rod-shaped support member 11, both ends of which are connected to the longitudinal beam; the fender assembly is connected to the rod-shaped support member 11, and the fender assembly is used to shield muddy water generated during the movement of the vehicle; wherein, the rod-shaped support member 11 is operated to deform in a preset direction and at a preset angle to adjust the fender assembly to a working position at different heights.

[0046] By applying the technical solution of the present invention, by operating the rod-shaped support member 11 to deform in a preset direction and at a preset angle, not only the stability and anti-rolling ability of the structure are enhanced, but also the installation height of the fender assembly can be flexibly adjusted to meet the needs of different vehicle models and usage scenarios, thereby improving the applicability of the fender assembly and the adaptability of the vehicle. This solution solves the technical problem that the fixed support structure in the prior art cannot adjust the 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 capacity 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 cracks, so that the part can still maintain a high structural integrity after bending. Compared with a solid structure, a hollow structure has better plasticity, and can further realize the deformation of the rod-shaped support member 11 in a preset direction to a preset angle, thereby achieving precise bending at a preset angle.

[0048] Furthermore, the rod-shaped support member 11 includes: a bending section 101, a straight section 121 and a support rod 15. The first end of the bending section 101 is connected to the base 12, and the second end of the bending section 101 is extended and arranged gradually away from the longitudinal beam along the thickness direction of the longitudinal beam; a bending section 101 is respectively arranged at both ends of the straight section 121, and the two bending sections 101 are arranged opposite to 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 bending section 101 is operated to deform in a preset direction to a preset angle, so that the straight section 121 and the support rod 15 drive the fender assembly to be located at working positions at different heights. In this solution, the bending section 101 can be deformed 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 realizing the adjustment of the height of the fender assembly, so that the fender assembly can more flexibly adapt to different vehicle heights and road conditions, and improve the effect of shielding mud and water.

[0049] It should be further explained that the base 12 is welded to both ends of the rod-shaped support member 11, and 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.

[0050] By connecting the base to the longitudinal beam, the force can be smoothly transmitted, avoiding the 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 load and bad 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.

[0051] like Figure 1 As shown, the straight section 121 is the main part of the rod-shaped support member 11, and the straight section 121 is located between the two bent sections 101, and plays the role of connecting and transmitting force. A bent section 101 is respectively arranged at both ends of the straight section 121, and the two bent sections 101 are arranged opposite to each other, forming a "V" or "Λ" shaped stable structure. Such a design helps the straight section 121 to move smoothly when the angle of the bent section 101 is changed, driving the support rod 15 and the fender assembly to adjust 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 achieving 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] Further, at least one bending section 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 is gradually extended 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 and has a first angle α, and the second end of the second segment 112 is gradually extended toward the side where another 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 is gradually extended toward the side where another 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 and has a second angle β, and the first angle α and the second angle β are both located on the side of the bending section 101 facing the longitudinal beam. This solution realizes more precise deformation control and adjustment of the height of the fender assembly by forming a plurality of sections of the bending section 101. By adjusting the connection angles between the first section 111, the second section 112, the third section 113 and the fourth section 114, i.e., the first angle α and the second angle β, the rise or fall of the fender assembly can be controlled, so that the adjustment range of the fender assembly can be wider and the precision can be higher, so that it can 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, and the first segment 111 is connected to the longitudinal beam through the base. The connection between the first segment 111 and the longitudinal beam forms the base point of the entire support assembly 1, ensuring the stability of the bending segment 101 during adjustment. The second end of the first segment 111 is gradually extended away from the longitudinal beam along the thickness direction of the longitudinal beam. Such a design enables the bending segment 101 to obtain a certain degree of freedom at the beginning, reducing direct contact and friction with the longitudinal beam, and avoiding damage to the longitudinal beam or the bending segment 101 itself during the adjustment process.

[0058] Optionally, the first end of the second segment 112 is connected to the second end of the first segment 111 to form a first angle α. By changing the size of the first angle α, the overall position of the bending segment 101 can be adjusted, thereby affecting the height position 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 bending segment 101 is located. Such a design helps to maintain a suitable distance between the bending segment 101 and the longitudinal beam, avoids interference with other structures during the adjustment process, and is also conducive to the transmission and balance of force.

[0059] Optionally, the first end of the third segment 113 continues to be connected to the second end of the second segment 112, and the second end is also gradually extended toward the side where the other bending segment 101 is located, focusing more on the connection and transition functions. The third segment 113 is provided to further enhance the structural strength of the bending segment 101, ensuring that the bending segment 101 can withstand sufficient load under different angle adjustments while maintaining the accuracy of its shape and position.

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

[0061] Specifically, the first angle α is in the range of 100° to 140°, the second angle β is in the range of 130° to 170°, the sum of the first angle α and the second angle β is γ1, wherein the range of γ1 is 265° to 275°. By accurately setting the range of the first angle α and the second angle β, the appropriate distance between the fender assembly and other components of the frame is ensured, thereby improving 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, a 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 the fender assembly to have enough 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 angle α and the second angle β is set to 270°, which can ensure that the rod-shaped support member 11 can maintain good toughness under the lateral force and will not easily undergo permanent deformation or breakage. When the vehicle rolls, this design can absorb part of the lateral force and reduce the impact of the roll on the fender assembly. At the same time, through the plastic deformation of the bending section 101, the force is dispersed to the entire support structure to avoid structural damage caused by the force being concentrated at a certain 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, which not only avoids the wear that may be caused by direct contact, but also ensures that the fender assembly has sufficient movement space under the action of lateral force, reduces unnecessary vibration and impact, and thus improves the stability and anti-roll performance of the fender assembly when the vehicle is driving.

[0066] Specifically, the length dimension of the third group segment 113 is greater than or equal to 80 mm. In this embodiment, when performing the bending process, if the length dimension S of the third group segment 113 is too small, it may cause excessive concentration of materials at the bend, resulting in a high stress area, thereby causing cracks or fractures during the bending process or after long-term use. S is not less than 80 to ensure that the bent tube can achieve the expected bending angle in the hot bending and cold bending processes while maintaining the stability of the shape and the accuracy of the size.

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

[0068] Furthermore, a third angle γ2 is formed between the profile line of the second segment 112 in the length direction and the horizontal plane, and the range of the third angle γ2 is 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 the mechanical properties during the deformation process are optimized, and it can be ensured that the fender assembly has a more significant effect of shielding mud and water at working positions of different heights.

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

[0070] Specifically, one end of the support rod 15 is connected to the straight section 121 through the transition plate 13, and a positioning structure is provided on the transition plate 13. The support rod 15 is connected to the transition plate 13 through the positioning structure. The height of the positioning structure can be adjusted. By adjusting the height of the positioning structure, the mud guard assembly can be adjusted to work at different heights. The positioning structure on the transition plate 13 can achieve fine adjustment of the height of the mud guard assembly, and the final installation height of the mud guard assembly can be accurately controlled to ensure that it can effectively block mud and water at various working positions at various heights.

[0071] The setting of the third angle γ2 enables the fender assembly to better adapt to changes in road conditions when the vehicle is driving dynamically. For example, when the vehicle passes through an uneven road, the angle γ2 can allow the fender assembly to have a certain elastic space in the vertical direction, reduce the direct impact on the support assembly 1, and improve the durability and stability of the entire device.

[0072] It should be further explained that the support assembly 1 also includes a reinforcing plate 14, which is arranged on both sides of the transition plate 13. The reinforcing plate 14 is welded to the straight section 121 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 1 from being excessively deformed or damaged when subjected to force.

[0073] Further, the positioning structure includes: an arc segment 131, the opening of the arc segment 131 extends downward along the height direction of the transition plate 13, and the diameter of the arc segment 131 is set in one-to-one correspondence with the outer diameter of the support rod 15; a vertical segment 132, an arc segment 131 is respectively set at both ends of the vertical segment 132, the two arc segments 131 are arranged oppositely, the width of the vertical segment 132 is set in one-to-one correspondence with the outer diameter of the support rod 15, and the height of the vertical segment 132 is adjustable, and the height of the vertical segment 132 is adjusted to adjust the working position of the fender assembly at different heights, wherein the maximum height difference between different working positions is H, wherein the range of H is 0 to 45 mm. Through the synergistic effect of the arc segment 131 and the vertical segment 132, the positioning structure not only realizes the precise control of the height of the fender assembly, but also greatly enhances the applicability and safety of the vehicle under complex working conditions.

[0074] like Figure 2 As shown, the arc segment 131 is designed to fit with the outer edge of the support rod 15, so as to ensure that the support rod 15 can be stably embedded in the positioning structure when the fender assembly is at different heights. The opening of the arc segment 131 is extended downward along the height direction of the transition plate 13. This design makes the movement of the support rod 15 in the vertical direction smoother, reducing the resistance and wear during the movement. The diameter of the arc segment 131 is set in a one-to-one correspondence with the outer diameter of the support rod 15, ensuring a close fit between the support rod 15 and the positioning structure, and improving the stability and reliability of the entire support system.

[0075] The vertical section 132 is an adjustable part in the positioning structure, and an arc section 131 is provided at each end thereof, and the two arc sections 131 are arranged opposite to each other, which forms a C-shaped or U-shaped positioning groove. The width of the vertical section 132 is set in a one-to-one correspondence with the outer diameter of the support rod 15, ensuring the stable lateral positioning of the support rod 15, avoiding lateral movement or shaking, and ensuring the stability of the fender assembly in high-load transportation 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 of 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 adapt to 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 and snowy roads, the height and position of the fender assembly may need to be adjusted immediately. The height adjustability of the positioning structure can quickly adjust the position of the fender assembly according to real-time road conditions, improving the safety and passability of the vehicle.

[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 the adjustable bending section and transition plate design, this solution realizes the flexible adjustment of the installation height of the fender assembly while maintaining a reasonable gap between the upper cover plate and the suspension leaf spring, thereby enhancing the adaptability and stability of the fender assembly, avoiding structural damage caused by vibration, and improving the overall anti-roll capability of the frame.

[0081] 2.
