[0002] For automobiles, especially medium and heavy-duty trucks, the mudguard bracket structure is one of the important components to ensure the safety of vehicle operation. Its main function is to securely install the mudguards on the chassis of the vehicle body to prevent stones, mud and other debris splashed up by the tires during driving from damaging the vehicle body, while keeping the vehicle's appearance clean.

[0003] However, when vehicles travel on complex road conditions, the impact and torsional forces from the frame or chassis can easily cause fatigue damage or even breakage of the mudguard brackets, affecting the normal use of the mudguards and increasing maintenance costs. Therefore, how to improve the impact resistance of the mudguard brackets and enhance their overall reliability has become an urgent problem to be solved. Utility Model Content

[0031] The mudguard bracket structure is one of the important components to ensure the safety of vehicle operation. Its main function is to securely install the mudguard on the vehicle chassis to prevent stones, mud and other debris splashed up by the tires during driving from damaging the vehicle body, while keeping the vehicle's appearance clean.

[0032] Existing mudguard bracket structures typically involve rigidly connecting a cast base to a steel pipe via welding. This makes the bracket prone to breakage when subjected to chassis impacts or torsion during vehicle operation, resulting in poor reliability.

[0033] In view of this, the present invention provides a mudguard bracket and a car. Through the synergistic effect of the first and second vibration damping structures, two-dimensional vibration damping paths can be formed in the axial and radial directions of the support member, which can effectively absorb or buffer vibration impact, reduce the probability of bracket breakage, and reduce maintenance frequency and replacement costs.

[0034] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a mudguard bracket, the mudguard bracket comprising:

[0036] Mounting base 100, having a through hole 110, is used to connect to a vehicle frame or chassis. It is understood that the mounting base 100 is mounted on the vehicle frame or chassis and can be fixed to the vehicle frame or chassis by bolts.

[0037] A support member 200 is inserted through the through hole 110. The support member 200 has a first end and a second end, the first end of which is used to mount a mudguard. It is understood that the support member is inserted through the through hole 110, and the first end extends outside the through hole 110 for mounting the mudguard. Optionally, the support member 200 can be a metal tubular structure such as a steel pipe or iron pipe.

[0038] The first vibration damping structure 300 is disposed at the second end of the support member 200. It can be understood that the first vibration damping structure 300 is disposed on the end face of the support member 200 near the chassis, to abut against the chassis and absorb vibration and impact from the chassis; and

[0039] The second vibration damping structure 400 is disposed between the inner wall of the through hole 110 and the outer wall of the support member 200, and the mounting base 100 and the support member 200 abut against their respective sides. It can be understood that the second vibration damping structure 400 is clamped between the inner wall of the through hole 110 and the outer wall of the support member 200, thus fixing the support member 200 and the mounting base 100. Vibration impacts transmitted from the chassis to the mounting base 100 can be buffered by the second vibration damping structure 400, thereby reducing the impact on the support member 200.

[0040] During assembly, the first damping structure 300 can be fixed to the second end of the support member 200 by adhesive bonding or other means, and the second damping structure 400 can also be fixed to the outer wall of the support member 200 by adhesive bonding or other means. Then, the mounting base 100 is inserted from the first end of the support member 200 until the first damping structure 300 and the second damping structure 400 are pressed together in the through hole 110, thereby fixing the support member 200 in the through hole 110. Optionally, for ease of assembly, the diameter of the through hole 110 increases gradually towards the chassis. Understandably, during assembly, the end of the through hole 110 near the chassis is inserted into the first end of the support member 200. Because the diameter of the through hole 110 near the chassis is larger, it can easily fit onto the outer periphery of the first end of the support member 200. As the mounting base 100 continues to slide along the axial direction of the support member 200, the second damping structure 400 and the first damping structure 300 gradually press against the inner wall of the through hole 110, thereby fixing the support member 200 in the through hole 110. Finally, the mounting base 100 is fixed to the chassis or frame using bolts, thus achieving the fixation of the entire fender bracket on the frame or chassis.

[0041] In one embodiment, to further improve the firmness of the support member 200 fixed in the through hole 110, an adhesive can be provided on the first vibration damping structure 300 to bond and fix the first vibration damping structure 300, the mounting base 100, and the support member 200 together; or an adhesive can be provided on the second vibration damping structure 400 to bond and fix the second vibration damping structure 400, the mounting base 100, and the support member 200 together.

[0042] Optionally, both the first damping structure 300 and the second damping structure 400 are made of elastic materials, which can better absorb and buffer vibrations when subjected to vibration impacts.

[0043] In the technical solution adopted in this implementation, by setting a first damping structure 300 at the second end of the support member 200, axial vibration and impact loads from the frame or chassis can be effectively buffered and absorbed, reducing the stress between the support member 200 and the frame, thereby reducing fatigue damage to the support member 200 caused by impact and extending the service life of the bracket. At the same time, a second damping structure 400 is set between the inner wall of the through hole 110 and the outer wall of the support member 200, which can provide elastic support in the radial direction, reduce the swaying and displacement of the support member 200 during vehicle operation, improve the stability of the mudguard installation, and prevent abnormal noise or connection failure caused by loosening; it can also buffer the impact load transmitted from the frame or chassis to the support member 200 through the mounting seat 100, further reducing the damage caused by impact to the support member 200 and preventing the support frame from breaking. This application, through the synergistic effect of the first vibration damping structure 300 and the second vibration damping structure 400, can form two-dimensional vibration damping paths in the axial and radial directions of the support member 200, which can effectively absorb or buffer vibration impact, reduce the probability of support breakage, and reduce maintenance frequency and replacement costs.

[0044] In one embodiment of this utility model, the first vibration damping structure 300 at least partially protrudes from the through hole 110, and the end face of the first vibration damping structure 300 facing away from the support member 200 is provided with a deformation recess 310. Thus, when the mounting base 100 is assembled to the chassis or frame, the first vibration damping structure 300 will first contact the frame, avoiding gaps between the mounting base and the frame, thereby improving the reliability of the mounting base 100 and the frame fixation, as well as the buffering effect against frame vibration impact. As the mounting base 100 is continuously tightened, the first vibration damping structure 300 is compressed and deformed under the tightening force of the mounting base 100 and the frame. The deformation recess 310 provides deformation space for the first vibration damping structure 300, ensuring that the first vibration damping structure 300 can effectively deform to adapt to the assembly requirements of the mounting base 100 and the frame. Optionally, the deformation recess 310 is arc-shaped or hemispherical, which helps to disperse stress.

[0045] In one embodiment of this utility model, reference is made to Figure 1 The mudguard bracket also includes a limiting structure 500, which is disposed between the second end and the first vibration damping structure 300 and connects the first vibration damping structure 300 and the second end. This facilitates the installation of the first vibration damping structure 300 and the support member 200, prevents the first vibration damping structure 300 from shifting, and ensures the vibration damping effect.

[0046] In one embodiment of this utility model, reference is made to Figure 2 The limiting structure 500 includes a limiting protrusion 510 and a limiting recess 520 that cooperates with the limiting protrusion 510. One of the second end and the first vibration damping structure 300 is provided with the limiting protrusion 510, and the other of the second end and the first vibration damping structure 300 is provided with the limiting recess 520. Specifically, during assembly, the limiting protrusion 510 can be inserted into the limiting recess 520 to achieve the positioning and installation of the support member 200 and the first vibration damping structure 300 without the need for other tools, making assembly simpler and more convenient. Optionally, the shapes of the limiting recess 520 and the limiting protrusion 510 can be hemispherical, square, or other irregular shapes, and are not limited here. Optionally, the limiting recess 520 is configured as a through hole penetrating the second end of the support member 200, and the limiting protrusion 510 is inserted into the through hole.

[0047] In one embodiment of this utility model, reference is made to Figure 2 The limiting protrusion 510 protrudes from the first vibration damping structure 300. The limiting protrusion 510 has a free end 511 and a fixed end 512. The fixed end 512 connects the free end 511 and the first vibration damping structure 300. The outer diameter of the limiting protrusion 510 decreases in the direction close to the fixed end 512. In this way, the end with the larger outer diameter of the limiting protrusion 510 will interfere with the limiting recess 520, preventing the limiting protrusion 510 from detaching from the limiting recess 520 after assembly.

[0048] In one embodiment of this utility model, the second vibration damping structure 400 is sleeved on the outer wall of the support member 200, which increases the contact area with the support member 200, which is beneficial for absorbing radial vibration impact and simplifies the assembly steps; or, multiple second vibration damping structures 400 are arranged at intervals along the circumference of the support member 200, which can save material usage and reduce production costs and overall weight.

[0049] In one embodiment of the present invention, the outer diameter of the second vibration damping structure 400 increases in the direction close to the first vibration damping structure 300, thereby preventing the second vibration damping structure 400 from falling off between the support member 200 and the mounting base 100.

[0050] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The outer wall of the second end is provided with a clamping flange 600, which extends radially along the support member 200. The first damping structure 300 covers the clamping flange 600, and the second damping structure 400 extends to the outer periphery of the clamping flange 600. Thus, after assembly, the second damping structure 400 can be clamped by the inner wall of the through hole 110 and the clamping flange 600. Under the rigid clamping force of the mounting base 100 and the clamping flange 600, the second damping structure 400 can be further prevented from falling off between the support member 200 and the mounting base 100, improving the reliability of the fixing of the mounting base 100, the support member 200, and the second support structure. In addition, the first damping structure 300, covering the clamping flange 600 and contacting the inner wall of the through hole 110, can buffer the vibration impact of the mounting base 100 on the clamping flange 600, thereby reducing the impact on the support member 200. Understandably, the first damping structure 300 protrudes radially from the clamping flange 600, thus preventing the clamping flange 600 from directly contacting the inner wall of the through hole 110.

[0051] In one embodiment of this utility model, the first vibration damping structure 300 and / or the second vibration damping structure 400 are configured as rubber parts. Rubber materials have excellent elastic deformation capacity and damping characteristics, which can effectively absorb vibration and impact energy. Moreover, the rubber parts can maintain stable performance under complex and harsh working conditions. And / or, the first vibration damping structure 300 and the through hole 110 are interference-fitted, which can further improve the fixing reliability of the support 200 in the through hole 110.

[0052] To achieve the above objectives, this utility model provides an automobile, which includes a frame and a mudguard bracket connected to the frame.

Specifically, the specific structure of the mudguard mounting bracket is as described in the above embodiments. Since this automobile adopts all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.
