[0028] Figure 1 It is a schematic diagram of the overall structure of the fender provided by an embodiment of the present utility model.

[0029] See Figure 1 The first aspect of an embodiment of the present invention provides a mudguard device, which includes a base 10, a support member 20 and a mudguard 30. The base 10 includes a supporting portion and a connecting portion. The supporting portion is used to fix the mudguard device to the vehicle body. The connecting portion is a tubular structure. The support member 20 is sleeved on the connecting portion of the base 10. The diameter of the base 10 gradually decreases from the supporting portion to the connecting portion. A clamp component 40 is sleeved on the outer side of the support member 20. The clamp component 40 is used to fix the support member 20 on the base 10. The mudguard 30 is provided on the support member 20. The shape of the mudguard 30 matches the shape of the vehicle tire.

[0030] See Figure 1 As can be appreciated, the mud guard device provided by the present embodiment secures the support member 20 to the base 10 via the clamp member 40, providing a more uniform tightening force and ensuring the stability and reliability of the connection. Compared to welding, the clamp connection is less likely to loosen or break under long-term use and in vibration environments. Furthermore, the clamp connection is relatively easy to disassemble and reinstall, facilitating after-sales repairs and component replacements. When repairs or component replacements are required, there is no need to disrupt the original structure, reducing repair costs and time.

[0031] Compared to the prior art, the clamp connection in the mud guard provided by the embodiment of the present invention facilitates a lightweight design because it allows the use of lighter materials (such as aluminum alloy) to manufacture the components while maintaining the stability and strength of the structure. Furthermore, when the base 10 is made of steel and the support member 20 is made of aluminum alloy, the welding properties of these two materials differ significantly, making direct welding difficult. By providing a clamp component 40 for fixation, the welding difficulties caused by the different materials can be avoided. Furthermore, aluminum alloy materials are prone to degradation of weld zone performance during welding, such as reduced strength in the heat-affected zone and weld cracks. Using the clamp component 40 for connection can avoid the welding process, thereby eliminating the risk of poor weld zone performance.

[0032] Figure 2 It is a schematic diagram of the explosion structure of the mud guard device provided in an embodiment of the utility model.

[0033] See Figure 1 and Figure 2 In an optional embodiment of the present invention, the support member 20 includes an aluminum alloy round tube, which is sleeved on the connecting portion of the base 10 and fixed by a clamp component 40, and the fender 30 is provided on the aluminum alloy round tube.

[0034] It is understandable that aluminum alloy is a lightweight material with a density much lower than that of steel. The use of aluminum alloy round tubes can significantly reduce the overall weight of the mudguard, which helps to achieve a lightweight design for the vehicle, thereby reducing fuel consumption and improving fuel efficiency. In addition, although aluminum alloy is light, it has good strength and rigidity. Through proper design and processing, aluminum alloy round tubes can provide sufficient structural support to ensure the stability and durability of the mudguard. In addition, aluminum alloy has good corrosion resistance. Compared with the plastic material in the prior art, aluminum alloy round tubes can maintain their performance under various environmental conditions and are not easy to rust. This is especially important for vehicle parts that are often exposed to harsh environments such as moisture and salt spray. In addition, aluminum alloy materials are easy to process and form, and can be made into round tubes through a variety of processes such as extrusion and forging, which provides flexibility and convenience for design and manufacturing. In addition, aluminum alloy is a recyclable material. The use of aluminum alloy round tubes helps to reduce the impact on the environment and is in line with the concept of sustainable development.

[0035] Continue reading Figure 1 and Figure 2In an optional embodiment of the present invention, the mudguard device further includes a connecting plate 50, which is arranged between the aluminum alloy round tube and the mudguard 30. The shape of the connecting plate 50 is adapted to the shape of the mudguard 30. It can be understood that the connecting plate 50 serves as an additional supporting component, which can enhance the structural stability of the entire mudguard device. Through the connecting plate 50, the mudguard 30 can be more firmly connected to the round tube, thereby improving the overall rigidity and reducing deformation or loosening caused by vibration and impact during vehicle driving.

[0036] Furthermore, during vehicle operation, the fender 30 may be subjected to lateral forces or torque. The connecting plate 50 effectively resists these forces, ensuring that the fender 30 maintains its correct position and orientation. In other words, the design of the connecting plate 50 prevents the fender 30 from rotating about the mounting point of the aluminum alloy tube. Furthermore, as a connecting and transitional component, the connecting plate 50 helps disperse and transfer stress, avoiding stress concentration and thereby improving the load-bearing capacity and durability of the entire fender assembly. In an optional embodiment of the present invention, the connecting plate 50 can be manufactured from a lightweight material (such as aluminum alloy). This helps achieve a lightweight design for the entire fender assembly while maintaining sufficient strength and rigidity.

[0037] Continue to refer to 1 and Figure 2 In an optional embodiment of the present invention, the mud guard device also includes a pressure strip 60, which is provided with at least one bolt, and the aluminum alloy round tube is provided with through holes corresponding to the position and number of the bolts. The pressure strip 60 is passed through the aluminum alloy round tube, and the bolts are suitable for passing through the through holes and then being fixed to the mud guard 30.

[0038] There are two ways to fix the bolts to the fender 30. The first is to set a threaded hole corresponding to the bolt on the fender 30, and the bolt can be screwed into the threaded hole after passing through the through hole to be fixed; the second is to set a nut corresponding to the bolt, and at the same time set a corresponding through hole on the fender 30. After the bolt passes through the through hole on the connecting plate 50 and the through hole on the fender 30, the bolt can be locked with the help of the nut, thereby realizing the assembly between the fender 30, the connecting plate 50 and the aluminum alloy round tube.

[0039] In an optional embodiment of the present invention, the connection between the aluminum alloy tube, the support member 20, and the fender 30 may also be achieved by bonding or clamping. For details, please refer to the prior art for adaptive design, and the present embodiment will not be described in detail here. It should be noted that the bolts provided on the bead 60 may be detachably connected to the bead 60 or pre-welded to the bead 60. Pre-welding the bolts on the bead 60 reduces welding work during on-site assembly and simplifies the assembly process. This design reduces the number and variety of parts, helps achieve lightweighting, and simplifies the production process. Specifically, the selection can be made based on actual conditions.

[0040] See Figure 1 and Figure 2 It can be understood that in the mudguard device provided by the embodiment of the present invention, a pressure strip 60 is provided and bolts are provided on the pressure strip 60. In this way, when the connecting plate 50, the mudguard 30 and the aluminum alloy round tube are assembled, these bolts can pass through the through holes on the aluminum alloy round tube, the connecting plate 50 and the mudguard 30, and the aluminum alloy round tube, the connecting plate 50 and the mudguard 30 are fastened with the help of nuts. This connection method provides a stable fastening point, which can ensure a firm connection between the mudguard 30 and the aluminum alloy round tube.

[0041] Continue reading Figure 1 and Figure 2 In an optional embodiment of the present invention, the clamp component 40 includes a first semicircular clamp, a second semicircular clamp and a fastener, the first end of the first semicircular clamp and the first end of the second semicircular clamp are rotatably connected, and the fastener is suitable for passing through the second end of the first semicircular clamp and then being fixed to the second end of the second semicircular clamp. When the fastener fixes the first semicircular clamp and the second semicircular clamp, the first semicircular clamp and the second semicircular clamp can form an annular structure corresponding to the aforementioned aluminum alloy round tube. It can be understood that the clamp component 40 formed by the first semicircular clamp, the second semicircular clamp and the fastener is easy to disassemble and install, which is beneficial to the assembly between the aluminum alloy round tube and the base 10, and any component therein can be directly disassembled and replaced after being damaged, which can greatly improve the assembly and installation efficiency of the mud guard device.

[0042] In an optional embodiment of the present invention, the fender 30 comprises an aluminum alloy fender. In other words, the fender 30 is made of an aluminum alloy. It is understood that aluminum alloy is a lightweight material. Compared to conventional plastic or steel fenders 30, the use of aluminum alloy can significantly reduce the weight of the fender 30, which helps achieve a lightweight design for the vehicle, thereby reducing fuel consumption and improving fuel efficiency. Furthermore, although aluminum alloy is light, it has good strength and rigidity. Through proper design and processing, the aluminum alloy fender can provide sufficient structural support, ensuring that it can effectively block mud, water, gravel, etc. during vehicle operation. Furthermore, aluminum alloy has excellent corrosion resistance and can maintain its performance under various environmental conditions, making it less susceptible to rust. This is particularly important for vehicle components that are frequently exposed to harsh environments such as moisture and salt spray. Compared to plastic fenders, aluminum alloy fenders do not have aging issues and can maintain their performance and appearance for a long time, extending their service life.

[0043] In an optional embodiment of the present invention, the thickness of the aluminum alloy fender is a, where a is 1.5-3 mm. For example, the thickness of the aluminum alloy fender can be set to 1.5 mm, 2 mm, or 3 mm. It can be understood that limiting the thickness of the aluminum alloy fender within the above-mentioned value range can provide sufficient structural strength and rigidity to ensure that it can effectively block mud, water, gravel, etc. during vehicle driving, while withstanding certain impacts and vibrations and maintaining a stable shape. In addition, aluminum alloy itself is a lightweight material. The thickness within the above-mentioned value range helps to reduce the weight of the fender 30 while ensuring strength, thereby achieving the lightweight design goal, reducing the overall weight of the vehicle, and improving fuel efficiency. Taking a 2 mm aluminum alloy fender as an example, the weight of the manufactured aluminum alloy fender is only 2 kg, which is about 50% lighter than that of a plastic fender. At the same time, compared with plastic, aluminum alloy material has higher strength and no aging risk.

[0044] Figure 3 It is a schematic diagram of the partial structure of the fender provided in an embodiment of the present utility model.

[0045] See Figure 1 and Figure 3 In an optional embodiment of the present invention, the fender 30 is provided with at least one reinforcing rib 31. If multiple ribs 31 are provided, they are spaced apart along the width of the fender 30. As will be appreciated, stamping the ribs 31 into the fender 30 increases its overall rigidity, reduces significant deformation of the fender 30 under conditions such as vehicle pitch, cornering, and braking, and ensures that the fender 30 effectively blocks mud, water, and gravel. Furthermore, the ribs 31 optimize material distribution without increasing the overall weight of the fender 30, thereby improving its performance. This design contributes to lightweighting while maintaining or improving the performance of the fender 30. Furthermore, because the ribs 31 enhance the structural strength and durability of the fender 30, they extend its overall service life and reduce the frequency of maintenance and replacement. Furthermore, the design of the ribs 31 more evenly distributes stress across the fender 30, avoiding stress concentration and thereby improving its load-bearing capacity and durability.

[0046] Figure 4 It is a schematic diagram of the partial structure of the fender provided by an embodiment of the present utility model from another perspective.

[0047] See Figure 4In an optional embodiment of the present invention, at least one side of the fender 30 is provided with a rolled edge 32, which is turned inward toward the inside of the fender 30. As can be appreciated, the provision of the rolled edge 32 increases the thickness and strength of the edge, making the edge area of the fender 30 more robust and more resistant to impact and abrasion. Furthermore, the rolled edge 32 effectively protects the edge of the fender 30 from damage and prevents scratches or cuts caused by sharp edges or burrs during installation or use, thereby improving the safety and service life of the product. Furthermore, the edge area of the fender 30 is prone to stress concentration due to sudden changes in shape. By smoothing the edge, the rolled edge 32 helps reduce stress concentration and improves the structural stability of the fender 30. Furthermore, the rolled edge 32 not only increases edge strength but also, by changing the shape of the edge, enhances the local stiffness of the fender 30, helping to reduce vibration and deformation of the fender 30 during vehicle operation.

[0048] The second aspect of an embodiment of the present invention provides a vehicle, which includes the mud guard device described in any one of the aforementioned embodiments. It can be understood that the vehicle provided by this embodiment, because it includes the mud guard device described in any one of the aforementioned embodiments, also has the beneficial effects of the mud guard device of any one of the aforementioned embodiments.

[0049] It should be noted that the technical solutions in the various embodiments of the present invention can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in this field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist, that is, it does not fall within the scope of protection of the present invention.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
