Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a wheel mudguard fixing device and vehicle. Background Technology

[0002] Most existing heavy-duty vehicle mudguards are made of rubber and are bolted to the subframe longitudinal beams and the bottom plate of the vehicle box. They are mainly used to prevent sand, mud and water thrown out by the wheels from splashing onto the vehicle body, pedestrians or other vehicles, thus avoiding damage to the vehicle structure and pedestrians.

[0003] Due to the harsh road conditions on which heavy vehicles travel, the mudguards are subjected to constant bumps, vibrations, and mud and water impacts. As a result, the rubber parts are prone to flexible deformation and shift towards the tire, causing wear and tear on the mudguards and loss of their shielding function. Existing mudguards are usually installed and fixed using mounting brackets (such as publication number CN202420182506.8). The mounting brackets are equipped with curved brackets to increase the contact area with the mudguards and improve the installation stability of the mudguards.

[0004] The existing method of using curved brackets to assist in supporting and limiting the mudguards, with the curved brackets installed on the front side of the mudguards, still cannot effectively prevent the mudguards from shifting to the rear (i.e., towards the tire). The mudguards are still very easy to rub against the tires. In addition, the existing mudguard installation structure has poor space limiting ability, and the mudguards are also very easy to tilt to the left and right sides, resulting in the failure of the blocking function. Utility Model Content

[0005] To address the technical problems of existing mudguard fixing structures in the background art, such as poor spatial limiting ability, inability to effectively restrict mudguard displacement, resulting in easy wear of mudguards and failure of the shielding function, this utility model provides a wheel mudguard fixing device and vehicle.

[0006] The technical solution of this utility model is as follows: This utility model provides a wheel mudguard fixing device, including a mudguard and a mounting plate. The upper part of the mudguard is fixedly connected to the mounting plate by bolts. The mounting plate is also fixedly connected to a space limiting frame by bolts. The space limiting frame is a round steel bending structure. The lower part of the mudguard is inserted into the space limiting frame. The mounting plate can fix the upper part of the mudguard, and the space limiting frame forms a spatial constraint on the lower part of the mudguard. It can form a more stable limit on the mudguard in the vertical, front-back, left-right directions, effectively reducing the displacement of the mudguard towards the tire, and also reducing the possibility of its left-right tilt.

[0007] Preferably, the space limiting frame includes two oppositely arranged connecting parts, which are vertically arranged. The upper part of the connecting parts has a mounting hole for mounting bolts. The bottom of the two connecting parts is fixedly connected by the limiting part. The mudguard is inserted and passes downward through the limiting part. The vertical arrangement of the connecting parts facilitates a stable connection with the mounting plate. The limiting part at the bottom can limit the lower part of the mudguard. After the mudguard is inserted, the lower part is constrained by the space formed by the limiting part, which further improves the limiting ability of the mudguard in the front-back and left-right directions, preventing it from tilting to the left and right sides and in the front-back direction, and ensuring the stable performance of the shielding function.

[0008] Preferably, the limiting part is a waist-shaped frame structure with an opening on one side, which not only provides space for the mudguard to be inserted, making installation and operation convenient, but also effectively blocks the mudguard through the side of the frame, reducing the mudguard's swaying in the front-back and left-right directions. At the same time, the opening design also makes it easy to disassemble and maintain the mudguard when needed, taking into account both practicality and convenience.

[0009] Preferably, the limiting part is provided with a positioning hole, the width of which is not less than the thickness of the mudguard. The positioning hole can cooperate with the mudguard. The width matching the thickness of the mudguard can prevent the mudguard from shaking excessively in the positioning hole, ensuring that the mudguard maintains a stable position during use, reducing the problem of obstruction failure caused by position deviation, and further enhancing the accuracy of the limiting.

[0010] Preferably, the connecting part is located on the side of the mudguard away from the tire, which can avoid interference between the connecting part and the tire. At the same time, it forms a pulling force and limit on the mudguard from the side away from the tire, which more effectively suppresses the displacement of the mudguard towards the tire, reduces the probability of friction between the mudguard and the tire, and ensures the safety of the vehicle when driving.

[0011] Preferably, the overall length of the connecting part is greater than half the length of the mudguard, and can extend from the upper part of the mudguard to a position closer to the lower part, so as to provide support and limit the mudguard over a longer range, allowing the mudguard to be constrained in multiple positions, reducing tilting or displacement caused by uneven local force, and improving the stability of the overall fixed structure.

[0012] Preferably, the connecting part includes two vertically arranged vertical sections, which are fixedly connected by an inclined section. This can better adapt to the shape of the mudguard, increase the contact area with the mudguard, and improve the limiting ability of the mudguard.

[0013] Preferably, the bolted connection has a self-locking nut, a first washer is provided between the self-locking nut and the mounting plate, and a second washer is provided between the self-locking nut and the connecting part. The self-locking nut can prevent the bolt from loosening during vehicle vibration, ensuring the stability of the connection between the mudguard, the mounting plate and the space limiter; the first and second washers can distribute the pressure, avoid wear caused by direct friction between the self-locking nut and the mounting plate and the connecting part, and extend the service life of each component.

[0014] Preferably, the mounting plate is located on the upper part of the mudguard, away from the tire. Fixing the upper part of the mudguard from the side away from the tire can cooperate with the space limit frame to limit the lower part of the mudguard, applying a stable force to the mudguard from both sides, further preventing the mudguard from shifting towards the tire, reducing the risk of friction, and at the same time not affecting the normal shielding function of the mudguard.

[0015] A vehicle employs the aforementioned wheel mudguard fixing device, which ensures that the mudguard maintains a stable position and is less prone to displacement towards the tire or tilting to the left or right. This avoids safety hazards caused by friction between the mudguard and the tire, while also ensuring that the mudguard's shielding function is effectively performed. This reduces vehicle malfunctions caused by mudguard issues and improves the safety and reliability of vehicle operation.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are: 1. The lower part of the mudguard is inserted into the space limiting frame. The installation pressure plate can fix the upper part of the mudguard. The space limiting frame forms a spatial constraint on the lower part of the mudguard, which can form a more stable limit on the mudguard from the vertical direction as well as the front-back and left-right directions. This effectively reduces the displacement of the mudguard towards the tire and also reduces the possibility of its left-right tilt.

[0017] 2. The limiting part is a waist-shaped frame structure with an opening on one side, which not only provides space for the mudguard to be inserted, making installation and operation convenient, but also effectively blocks the mudguard through the side of the frame, reducing the mudguard's swaying in the front-back and left-right directions. At the same time, the opening design also makes it easy to disassemble and maintain the mudguard when needed, taking into account both practicality and convenience. Attached Figure Description

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Example 1 In a typical embodiment of this utility model, such as Figures 1-5 As shown, a wheel mudguard fixing device is proposed, including: mudguard 1, space limiting frame 2 and mounting plate 3. The mudguard 1 is made of rubber. The upper part of the mudguard 1 and the upper part of the space limiting frame 2 are both fixedly installed on the mounting plate 3 by bolts 4. The mounting plate 3 is used to fix the mudguard 1 at the installation position at the bottom of the vehicle body. The lower part of the mudguard 1 is inserted into the space limiting frame 2 so as to limit the periphery of the mudguard 1 by the space limiting frame 2.

[0022] Space limiting frame 2 is a round steel bending structure, which is made by bending a single round steel bar into an irregular frame, as shown in the following figure. Figure 4 and Figure 5As shown, the space limiting frame 2 has a centrally symmetrical structure. The space limiting frame 2 includes a mounting hole 201, a positioning hole 202, a connecting part 203, and a limiting part 204. There are two connecting parts 203. The bottoms of the two connecting parts 203 are fixedly connected by the limiting part 204. The connecting parts 203 are arranged vertically. The upper part of each of the two connecting parts 203 is provided with a mounting hole 201. The mounting hole 201 is used for the installation of bolts 4 to realize the fixed connection between the upper part of the connecting part 203 and the mounting pressure plate 3. The limiting part 204 is a waist-shaped frame structure with an opening on one side (specifically, the side away from the tire). The limiting part 204 is provided with a positioning hole 202 for the insertion of the mudguard 1. The mudguard 1 can be inserted into the limiting part 204 to limit the mudguard 1.

[0023] A connecting part 203 is fixedly connected to each end of the opening of the limiting part 204. The connecting part 203 has a multi-segment bending structure. The overall length of the connecting part 203 is greater than half the length of the mudguard 1. Specifically, the connecting part 203 includes a vertical segment 2031 and an inclined segment 2032. The vertical segment 2031 has two segments, both of which are vertically arranged. The two vertical segments 2031 are fixedly connected by the inclined segment 2032 to expand the contact area between the connecting part 203 and the mudguard 1 and improve the limiting ability of the mudguard 1.

[0024] like Figure 2 and Figure 3 As shown, the mounting plate 3 is installed on the front side of the upper part of the mudguard 1 (i.e., the side away from the tire) and is fixedly connected to the mudguard 1 by bolts 4. The mounting plate 3 has several bolt holes spaced apart along its length, and the corresponding position on the upper part of the mudguard 1 also has several bolt holes. The bolts 4 pass through the bolt holes on the mudguard 1 and the mounting plate 3 in sequence and are threadedly connected to the self-locking nut 5 to achieve a fixed connection between the upper part of the mudguard 1 and the mounting plate 3.

[0025] The upper part of the space limiting frame 2 is fixedly connected to the mounting pressure plate 3 by bolts 4. Specifically, the connecting part 203 is located on the front side of the mudguard 1 (i.e., the side away from the tire). The mounting hole 201 on the connecting part 203 is aligned with the bolt hole on the mounting pressure plate 3. The bolt 4 passes through the mudguard 1, the mounting pressure plate 3, and the connecting part 203 in sequence and is threadedly connected to the self-locking nut 5 to realize the installation and fixation of the space limiting frame 2. The bottom of the mudguard 1 is inserted and passes downward through the positioning hole 202 on the limiting part 204. The limiting part 204 is used to limit the lower part and the periphery of the mudguard 1 to prevent the mudguard 1 from shifting. The width of the positioning hole 202 is not less than the thickness of the mudguard 1 to ensure the buffering performance of the mudguard 1.

[0026] like Figure 2As shown, a first washer 6 is provided between the self-locking nut 5 and the mounting plate 3, and a second washer 7 is provided between the self-locking nut 5 and the connecting part 203. The size of the second washer 7 is larger than that of the first washer 6 to reduce wear between the self-locking nut 5 and the mounting plate 3 and the connecting part 203.

[0027] The space limiting frame 2 is made of a single round steel rod bent into shape. While limiting the space of the mudguard 1, it also reduces the obstruction of the mudguard 1. The overall structure is simple and lightweight, easy to install and use, and the replacement of the mudguard 1 is also more convenient.

[0028] The specific usage method is as follows: Place the mudguard 1 into the positioning hole 202 of the limiting part 204 at the bottom of the space limiting frame 2. Place the mounting plate 3 on the upper rear side of the mudguard 1. Use bolts 4, self-locking nuts 5, first washers 6, and second washers 7 to fix the connecting part 203, mudguard 1, and mounting plate 3 to the mudguard fixing point at the bottom of the box. By installing the mudguard 1 in the positioning hole 202 of the limiting part 204 at the bottom of the space limiting frame 2, the front-to-back displacement of the mudguard 1 is restricted, the displacement of the mudguard towards the tire is suppressed, and friction with the tire is eliminated. At the same time, the displacement of the mudguard in the left and right directions is suppressed, preventing the mudguard from losing its shielding function and causing mud and water to splash and contaminate vehicle parts.

[0029] Example 2 In one typical embodiment of this utility model, a vehicle is proposed that adopts the wheel mudguard fixing device mentioned in Embodiment 1. While retaining the buffering performance of the mudguard 1, it prevents the mudguard 1 from shifting excessively towards the tire, eliminates the friction between the mudguard 1 and the tire, and improves the service life of the mudguard 1. The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
