[0029] The following description, in conjunction with the accompanying drawings, describes a motorcycle rear mudguard device according to an embodiment of the present invention.
[0030] Reference Figure 1 The present invention aims to provide an embodiment of a motorcycle rear mudguard device.
[0031] A motorcycle rear mudguard device according to an embodiment of the present invention includes a front arc plate 100, a rear arc plate 110, and a fixing frame 120. The front arc plate 100 and the rear arc plate 110 are distributed along the circumference of the wheel. The fixing frame 120 connects and fixes the front arc plate 100 and the rear arc plate 110 and is installed on the motorcycle frame. The fixing frame 120 includes a first frame 130 and a second frame 140. The first frame 130 is connected to the second frame 140. The first frame 130 is used to install and fix the front arc plate 100 and is arranged on opposite sides along the width direction of the front arc plate 100. The second frame 140 is used to install and fix the rear arc plate 110 and extends along the center of symmetry of the rear arc plate 110.
[0032] It is understood that this utility model, by setting a fixing frame 120, which is composed of a first frame 130 and a second frame 140, uses the first frame 130 and the second frame 140 to install the front arc plate 100 and the rear arc plate 110 respectively, and rigidly connects the first frame 130 and the second frame 140 together, and then fixes the entire device to the vehicle frame, avoiding stress concentration at the direct connection of the traditional split arc plates. The first frame 130 is arranged along both sides of the front arc plate 100 to provide a wide support surface, and the second frame 140 extends along the center of the rear arc plate 110 to provide a central rigid support, which together enhances the bending and torsional resistance and overall strength of the entire mudguard device, effectively preventing breakage at the connection and overall deformation. In addition, the split design of the first frame 130 and the second frame 140 reduces the manufacturing difficulty of the fixing frame 120 and also reduces the assembly difficulty of the rear mudguard device.
[0033] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 The first frame 130 has two first support bars 150 located on the concave side of the front arc plate 100. The first support bars 150 extend along the edge of the front arc plate 100 in the width direction and are in contact with the concave side of the front arc plate 100.
[0034] Understandably, the two first support bars 150 fit against the concave side of the front arc plate 100 and extend along its width edge, which enhances the rigidity of the weak edge of the front arc plate 100, effectively suppresses the bending and twisting deformation of the front arc plate 100 under bumps, and improves the durability of the front arc plate 100.
[0035] In addition, concealing the two first support bars 150 within the concave side of the front arc plate 100 improves the aesthetics of the mudguard device.
[0036] In a further embodiment of this utility model, referring to Figure 1 and Figure 3 The front arc plate 100 is provided with a first extension section 160 on the side away from the rear arc plate 110. The first extension section 160 is provided with a first limiting groove 170, which is used to accommodate the end of the first support bar 150.
[0037] Understandably, the first limiting groove 170 on the first extension section 160 forms a physical constraint on the end of the first support bar 150, preventing it from moving axially or radially when vibrating or under stress, thus ensuring that the relative position of the first support bar 150 and the front arc plate 100 remains stable, thereby guaranteeing the support effect of the first frame 130 on the front arc plate 100. In addition, the use of the first limiting groove 170 to limit the end of the first support bar 150 also improves the installation efficiency between the front arc plate 100 and the first frame 130.
[0038] In a further embodiment of the present invention, a first bolt 180 is provided between the first extension section 160 and the first support bar 150. The first bolt 180 is connected to the motorcycle frame to install and fix the front arc plate 100 and the first frame 130.
[0039] Understandably, by using the first bolt 180 to pass through the first support bar 150 and the first extension section 160 and connect it to the frame, the front arc plate 100 and the first frame 130 are firmly installed on the frame body. This reduces the number of parts and connection points and enhances the rigid connection between the front arc plate 100 and the frame.
[0040] In a further embodiment of this utility model, referring to Figure 4 The first frame 130 has a first connecting bar 190 and a second connecting bar 200 that connect two first support bars 150. The second frame 140 has a first mounting part 210, which is connected and fixed to the first connecting bar 190 and the second connecting bar 200.
[0041] Understandably, the first connecting bar 190 and the second connecting bar 200 connect the two first support bars 150 into a stable frame structure, which significantly improves the overall rigidity of the first frame 130.
[0042] In addition, by connecting the first mounting plate with the first connecting strip 190 and the second connecting strip 200, the contact area at the connection between the first frame 130 and the second frame 140 is increased, providing a robust interface and ensuring that the connection between the front arc plate 100 and the rear guard plate is not easily broken.
[0043] In a further embodiment of this utility model, referring to Figure 5 The rear arc plate 110 is provided with a second extension section 220 on the side near the front arc plate 100. The second extension section 220 is provided with a second bolt, which is connected to the end of the first support bar 150.
[0044] Understandably, the second extension 220 is located on the side of the rear arc plate 110 close to the front arc plate 100 and is connected to the end of the first support bar 150 by the second bolt, which further increases the rigid connection point of the connection area between the front arc plate 100 and the rear arc plate 110. This further reduces the risk of breakage at the connection and enhances the overall rigidity of the junction area between the front arc plate 100 and the rear arc plate 110.
[0045] In addition, the second bolt passes through the second extension section 220 from the concave side of the front arc plate 100 and screws into the first support bar 150, which can hide the second bolt, avoid the bolt connection structure from being exposed, and improve the aesthetics of the mudguard device.
[0046] In some embodiments of this utility model, the second frame 140 has a second support bar 240, and a second limiting groove 250 is provided on the outward convex side of the rear arc plate 110, the second limiting groove 250 accommodating the second support bar 240.
[0047] Understandably, the cooperation between the second limiting groove 250 and the second support bar 240 allows the second support bar 240 to be precisely fitted onto the outer convex side of the rear arc plate 110 and located at the symmetrical center of the rear arc plate 110. In this way, the second limiting groove 250 not only provides an installation positioning reference, but more importantly, it provides a support surface for the key stress area of the rear arc plate 110, significantly improving the rigidity and resistance to bending deformation in the middle of the rear arc plate 110.
[0048] In some embodiments of this utility model, the second support bar 240 is provided with a connecting column 260, and the rear arc plate 110 is provided with a third bolt 270. The third bolt 270 is connected to the connecting column 260 to fix the rear arc plate 110.
[0049] Understandably, the third bolt 270 passes through the concave side of the rear arc plate 110 and screws into the connecting post 260 of the second support bar 240, which can hide the third bolt 270, avoid exposing the bolt connection structure, and improve the aesthetics of the mudguard device.
[0050] In some embodiments of this utility model, a taillight 280 is also included. The second frame 140 has a second mounting part 290, which is located on the side of the rear arc plate 110 away from the front arc plate 100. The taillight 280 is mounted on the second mounting part 290.
[0051] It is understandable that the taillight 280 is mounted on the second mounting part 290 of the second frame 140, rather than directly on the rear arc plate 110, to avoid drilling holes or applying installation stress to the rear arc plate 110, and to prevent the rear arc plate 110 from deforming or breaking due to bearing the weight of the taillight 280.
[0052] In addition, the use of a more rigid mounting bracket 120 as a mounting base provides a more stable and robust support platform for the taillight 280, ensuring the reliable operation of the taillight 280 and simplifying assembly.
[0053] In some embodiments of this utility model, a step 300 is provided on the side of the rear arc plate 110 near the front arc plate 100, and the edge of the rear arc plate 110 matches the step 300.
[0054] Understandably, the step 300 structure provides additional support and reinforcement to the edge portion of the rear arc plate 110, improving the strength of the edge area and preventing misalignment between the rear arc plate 110 and the front arc plate 100.
[0055] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
