Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] The following is combined with Figs. 1-3 The following describes embodiments of the present invention.

[0039] According to an embodiment of the present invention, a mudguard and a working vehicle having the mudguard are provided, comprising: a fixing plate 1, adapted to be connected to the body of the working vehicle and disposed near the wheel of the working vehicle; a mudguard body 2, detachably connected to the fixing plate 1 and disposed at least partially overlapping the fixing plate 1; and a sealing structure 9, connected to at least a portion of the edge of the fixing plate 1 and covering the edge of the fixing plate 1 at the overlapping portion.

[0040] In this embodiment, the baffle body 2 and the fixed plate 1 are at least partially overlapped, and a sealing structure 9 is provided at the overlap position to seal the baffle body 2 and the fixed plate 1. With the sealing effect of the sealing structure 9, mud and water are effectively prevented from splashing into the equipment from the gaps, greatly improving the actual mud-blocking effect of the baffle. By overlapping the baffle body 2 and the fixed plate 1, a foundation is provided for the installation of the sealing structure 9. The sealing structure 9 is set to completely cover the edge of the overlapping part of the fixed plate 1, so that a continuous seal is formed between the baffle body 2 and the fixed plate 1, effectively blocking the intrusion of mud and water and providing a comprehensive protection effect.

[0041] In this embodiment, at least a portion of the baffle body 2 and the fixed plate 1 overlap, and a sealing structure 9 is provided at the overlapping position. The sealing structure 9 also covers the edge of the overlapping portion of the fixed plate 1, thereby reducing the direct contact surface between the baffle body 2 and the fixed plate 1, thus reducing frictional loss between the baffle body 2 and the fixed plate 1. Furthermore, under the vibration effect of the working vehicle, the sealing assembly can also effectively reduce the collision or friction between the baffle body 2 and the fixed plate 1, effectively reducing frictional wear and improving service life.

[0042] In some embodiments, the sealing structure 9 includes a first sealing member 3, which is disposed on the side of the fixing plate 1 facing the baffle body 2 and sandwiched between the fixing plate 1 and the baffle body 2.

[0043] Specifically, the first sealing element 3 is the part of the sealing structure 9 that mainly plays a sealing role. The first sealing element 3 can be, but is not limited to, a sealing strip. The first sealing element 3 is sandwiched between the overlapping part of the baffle body 2 and the fixed plate 1, and its two sides abut against the plate surfaces of the fixed plate 1 and the baffle body 2 respectively, thereby eliminating the gap between the fixed plate 1 and the baffle body 2, preventing mud and water and other pollutants from entering from between the fixed plate 1 and the baffle body 2, and ensuring the normal operation of the working vehicle.

[0044] Furthermore, the first sealing element 3 is provided on the edge of the fixed plate 1. The first sealing element 3 is a strip and is continuously arranged along the edge of the fixed plate 1. Thus, when the baffle body 2 of different sizes is assembled with the fixed plate 1, it can achieve a sealing effect and form a continuous seal between the baffle body 2 and the plate surface of the fixed plate 1, effectively blocking the mud and water splashed by the wheel.

[0045] In some embodiments, the sealing structure 9 further includes a second sealing member 4 and a third sealing member 5. The first end of the second sealing member 4 is connected to the first sealing member 3 at a preset angle, and the second end of the second sealing member 4 is connected to the third sealing member 5 at a preset angle. The third sealing member 5 is arranged at a distance from the first sealing member 3, so that the first sealing member 3, the second sealing member 4 and the third sealing member 5 surround and form a mounting groove 6. The edge of the fixing plate 1 is inserted into the mounting groove 6.

[0046] Specifically, the sealing structure 9 is a compression fitting structure. The second sealing element 4 and the third sealing element 5 cooperate with the first sealing element 3 to form an installation groove 6 for insertion and mating with the edge of the fixed plate 1. The sealing structure 9 is clamped at the fixed plate 1 by means of the installation groove 6 and the first sealing element 3 and the third sealing element 5, which can prevent the sealing structure 9 from shifting or moving when the baffle body 2 is assembled with the fixed plate 1. Furthermore, the sealing structure 9 is continuously sleeved and wrapped around the edge of the fixed plate 1, which can avoid the formation of sealing dead corners and ensure an all-round sealing effect.

[0047] In some embodiments, the sealing structure 9 further includes a fourth sealing element 8, which is connected to the side of the second sealing element 4 facing away from the fixing plate 1, and the fourth sealing element 8 abuts against the baffle body 2.

[0048] Specifically, the first sealing element 3, the second sealing element 4, the third sealing element 5, and the fourth sealing element 8 are all continuously arranged strips, and are integrally formed. The cross-sectional shape of the fourth sealing element 8 can be, but is not limited to, a hollow cylinder. The peripheral wall of the fourth sealing element 8 abuts against the baffle body 2, which initially blocks mud and water. Furthermore, the hollow cylindrical shape reduces the impact of mud and water splashing, preventing mud and water from entering the machine body.

[0049] In some embodiments, the baffle body 2 includes a main plate 25 and an inner folding plate 23. The main plate 25 is connected to the fixing plate 1 near the first end. The second end of the main plate 25 is connected to the first end of the inner folding plate 23. The second end of the inner folding plate 23 extends toward the side where the fixing plate 1 is located relative to the first end of the inner folding plate 23, so that the main plate 25 and the inner folding plate 23 are connected at a preset angle.

[0050] Specifically, the inner folding plate 23 is inclined relative to the main plate 25. Specifically, the second end of the inner folding plate 23 extends toward the side where the fixed plate 1 is located relative to the first end of the inner folding plate 23. With this configuration, when the working machinery is working, the rotation of the wheels will cause mud and water to splash. The inner folding plate 23 is set as a folded edge. Compared with the flat plate, the inner folding plate 23 is adapted to the splash trajectory of mud and water, which can effectively block rainwater from splashing forward.

[0051] Furthermore, while blocking mud and water splashes, the inner folding plate 23 also serves as a guide and structural reinforcement. The inner folding plate 23 is inclined relative to the main plate 25, and under the action of gravity, it can effectively guide the mud and water adhering to the plate surface to flow downwards and drip down, providing a cleaning effect and preventing the mudguard from becoming too dirty. In addition, the inner folding plate 23 and the main plate 25 form an L-shaped reinforcing rib structure, which increases the overall bending strength of the mudguard compared to a flat plate. This can effectively reduce the vibration deformation of the working vehicle, effectively improve the impact resistance, and extend the service life.

[0052] In some embodiments, the main body plate 25 includes a fourth plate segment 21 and a third plate segment 24 connected together, the third plate segment 24 being detachably connected to the fixing plate 1; wherein, the fourth plate segment 21 corresponds to the sealing structure 9, the fourth plate segment 21 protrudes in a direction away from the fixing plate 1 to form an installation gap 26 between the fourth plate segment 21 and the fixing plate 1; at least a portion of the sealing structure 9 is located within the installation gap 26, and its two sides abut against the fourth plate segment 21 and the fixing plate 1 respectively; the fourth plate segment 21 extends beyond the edge of the fixing plate 1 to form an overhang portion 211.

[0053] It should be noted that the specific structural form of the main plate 25 is not limited, as long as it has a third plate segment 24 connected to the fixed plate 1 and a fourth plate segment 21 that cooperates with the sealing structure 9. The structural forms of the third plate segment 24 and the fourth plate segment 21 can be, but are not limited to, those in this embodiment.

[0054] It should be noted that the purpose of the fourth plate segment 21 is to form an installation gap 26 between the baffle body 2 and the fixed plate 1, and to provide a sealing structure 9 at the installation gap 26 to achieve a seal between the baffle body 2 and the fixed plate 1. Furthermore, the method of forming the installation gap 26 is not limited, and it can also be provided such that the fixed plate 1 protrudes in a direction away from the fourth plate segment 21 to form the installation gap 26 between the fourth plate segment 21 and the fixed plate 1. Specifically, the corresponding plate segment of the fixed plate 1 can be provided to protrude in a direction away from the fourth plate segment 21 so that the sealing structure 9 can be installed at the corresponding plate segment, as long as at least a part of the sealing structure 9 is located between the fixed plate 1 and the baffle body 2, and both sides abut against the fixed plate 1 and the baffle body 2 respectively.

[0055] Specifically, the fourth plate segment 21 is continuously arranged with the third plate segment 24. The fourth plate segment 21 corresponds to the position of the sealing structure 9. Since the sealing structure 9 is connected to the edge of the fixed plate 1, the fourth plate segment 21 is arranged beyond the edge of the fixed plate 1 to ensure good cooperation between the fourth plate segment 21 and the sealing structure 9.

[0056] Combination Fig. 2 As shown, an installation gap 26 is formed between the fourth plate segment 21 and the fixed plate 1, and the fourth plate segment 21 is set beyond the edge of the fixed plate 1. The first sealing member 3 is sandwiched between the edge plate of the fourth plate segment 21 and the fixed plate 1. The opposite sides of the fourth sealing member 8 abut against the plate surfaces of the fourth plate segment 21 and the fixed plate 1 respectively to form a good seal.

[0057] Furthermore, since the fourth plate segment 21 protrudes relative to the third plate segment 24 and also protrudes relative to the first plate segment 22, a U-shaped flange is formed at the main plate 25. The U-shaped flange includes the fourth plate segment 21 and the transition section between the fourth plate segment 21 and the third plate segment 24, and the transition section between the fourth plate segment 21 and the first plate segment 22. The opening of the U-shaped flange faces the side of the fixed plate 1. The U-shaped flange can guide the flow of mud and water, and together with the inner folding plate 23, it plays a guiding role and improves the performance of the mudguard.

[0058] In some embodiments, the main body plate 25 further includes a first plate segment 22, which connects the fourth plate segment 21 and the inner folding plate 23; the first plate segment 22 extends in a direction parallel to the surface of the fixed plate 1; the fourth plate segment 21 protrudes from the first plate segment 22 toward the side away from the fixed plate 1.

[0059] Specifically, the first plate segment 22 is used to connect the fourth plate segment 21 and the inner folding plate 23. At the same time, the first plate segment 22 is parallel to the surface of the fixed plate 1, so that the inner folding plate 23 has a certain distance from the fixed plate 1, thereby increasing the coverage of the mudguard and improving the ability of the inner folding plate 23 to block mud and water splashing.

[0060] In some embodiments, a first mounting hole 241 is provided at the third plate segment 24, and a second mounting hole 11 is provided at the fixing plate 1. The first mounting hole 241 and the second mounting hole 11 are aligned. The mudguard also includes a fastening component 7, which cooperates with the first mounting hole 241 and the second mounting hole 11 to connect the baffle body 2 and the fixing plate 1, so that the third plate segment 24 is connected to the fixing plate 1.

[0061] Specifically, the fastening component 7 can be, but is not limited to, a bolt 71, a nut 72, and a washer. The bolt 71 passes through the first mounting hole 241 and the second mounting hole 11 in sequence and then extends out. The nut 72 is screwed and fixed to the extended end of the bolt 71. The washer is placed between the end of the bolt 71 and the plate surface, so that the fixing plate 1 and the baffle assembly can be detachably connected together and the connection is stable. This replaces the welding connection method in related technologies, avoids stress concentration caused by welding, and allows for quick disassembly, making subsequent cleaning and maintenance convenient and quick.

[0062] In some embodiments, both the fixing plate 1 and the baffle body 2 are arc-shaped plates, specifically circular arc curves. The arc-shaped fixing plate 1 and baffle body 2 are positioned above or to the side of the wheel. The arc-shaped plates can effectively block mud and water splashes, improving the mudguard's performance.

[0063] In some embodiments, the second mounting hole 11 is a strip-shaped hole, which extends along the arc direction of the fixing plate 1. This makes it easy to adjust the extension length of the baffle body 2 relative to the fixing plate 1 in the arc direction when the baffle body 2 is installed with the fixing plate 1, thereby adapting to wheels of different widths.

[0064] In some embodiments, a plurality of second mounting holes 11 are spaced apart along the axis surrounding the fixing plate 1; a plurality of first mounting holes 241 are provided, and the plurality of first mounting holes 241 correspond one-to-one with the plurality of second mounting holes.

[0065] Specifically, when the baffle body 2 and the fixing plate 1 are fitted together, the first mounting hole 241 and the second mounting hole 11 first play a positioning role. When installing the mudguard flange, the first mounting hole 241 on the baffle body 2 and the second mounting hole 11 on the fixing plate 1 are aligned one by one, which can quickly achieve the desired alignment and save a lot of time when installing the baffle body 2 and the fixing plate 1.

[0066] The specific usage of the mudguard is as follows: First, prepare the components to be assembled, including the sealing structure 9, the fixing plate 1, the mudguard body 2, and the fastening assembly 7. Then, insert the edge of the fixing plate 1 into the mounting groove 6 of the sealing structure 9, and simultaneously install the continuously arranged sealing structures 9 along the edge of the fixing plate 1 to the fixing plate 1, so that the sealing structure 9 and the fixing plate 1 are in a good fit. After that, the mudguard body 2 can be installed. When installing the mudguard body 2, align the first mounting holes 241 one by one, place a gasket at the first mounting hole 241, insert the bolt 71 into the hole, and tighten it with the nut 72 to fix it, so that the mudguard body 2 and the fixing plate 1 are firmly fixed together. At the same time, the first sealing element 3 of the sealing structure 9 is clamped between the mudguard body 2 and the fixing plate 1, and the installation of the mudguard is completed.

[0067] According to an embodiment of the present invention, another aspect provides a work vehicle including a mudguard as described in any of the preceding claims.

[0068] Specifically, the operating vehicle can be, but is not limited to, a loader.

[0069] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
