[0001] This utility model relates to the field of electric vehicle mounting bracket technology, and in particular to a mudguard adapter bracket, mudguard assembly and electric vehicle. Background Technology

[0002] With the rapid development of electric vehicles, the number of people riding them is growing rapidly. Electric vehicles are generally equipped with mudguards to protect riders from mud and water splashed out by the rear wheels during rain and snow. Existing mudguards typically consist of a mudguard body connected to the vehicle body via a connecting mechanism; the structure is very simple, and the mud-blocking effect is excellent.

[0003] In pursuit of aesthetics, some car models have relatively wide front wheel mudguards.

[0004] However, the upper part of the front wheel fender is only fixed to the front fork steering gear by 2 to 3 bolts. The lower part of the larger front wheel fender is far from the upper cantilever, with a lot of unsupported space. This makes the front wheel fender prone to making abnormal noises during the ride, affecting the riding experience. Moreover, the lifespan of the front wheel fender is also relatively short. After riding for a long time, the front wheel fender is prone to cracking or making abnormal noises, which greatly affects the use by consumers. Utility Model Content

[0005] In view of this, one of the objectives of this utility model is to provide a mudguard adapter bracket to solve the technical problem that some electric vehicles have a rounded shape for their front wheel mudguards, which are relatively wide and are only fixed to the front fork steering gear with 2 to 3 bolts. This causes the front wheel mudguard to make abnormal noises during riding, affecting the rider's riding experience and reducing the service life of the mudguard.

[0006] The second objective of this invention is to provide a mudguard assembly containing a mudguard adapter bracket.

[0007] A third objective of this invention is to provide an electric vehicle containing a mudguard assembly.

[0008] To achieve one of the above objectives, this utility model provides a mudguard adapter bracket, including a bracket body for installation in the inner cavity of the mudguard. The bracket body is arranged along the longitudinal extension direction of the mudguard and has a plurality of mounting points thereon. The mounting points are used to install the bracket body in the inner cavity of the mudguard and the fork steerer.

[0009] Optionally, the bracket body includes a first rod and a second rod, the first rod and the second rod are spaced apart by a preset distance and are arranged in a fork shape, the first rod and the second rod are both arranged along the longitudinal extension direction of the mudguard, the end of the first rod is provided with a first mounting point, and the end of the second rod is provided with a second mounting point;

[0010] The support body also includes a hollow plate, with the first rod and the second rod located at the bottom of the hollow plate.

[0011] Optionally, the first mounting point has a plate-like structure and the angle between it and the first rod is greater than 90 degrees.

[0012] Optionally, the second mounting point has a plate-like structure and the angle between it and the second rod is greater than 90 degrees.

[0013] Optionally, the hollow plate is integrally formed with the first rod and the second rod.

The angle between the fourth installation point and the fifth installation point and the hollow plate is greater than 90 degrees.

[0017] To achieve the second objective mentioned above, this utility model provides a mudguard assembly, including a mudguard and a mudguard adapter bracket as described above. The mudguard adapter bracket is installed in the inner cavity of the mudguard. The inner wall of the mudguard cavity is provided with an angular structural member adapted to the first mounting point and the second mounting point.

[0018] To achieve the third objective mentioned above, this utility model provides an electric vehicle, including the mudguard assembly as described above.

[0019] The mudguard adapter bracket provided by this utility model has the following technical advantages: Unlike existing technologies that rely solely on a few bolts to secure the mudguard at the top, leading to free-end vibration in the suspended area, this invention addresses this issue by incorporating a longitudinally extending support body within the mudguard's inner cavity. This, combined with multi-point fixing to form distributed support, effectively suppresses vibration transmission paths, eliminates structural fatigue caused by free-end vibration, enhances the rigidity of the mudguard's suspended area, reduces abnormal noises caused by vibration during riding, and simultaneously reduces the risk of mudguard cracking through stress dispersion, thus extending the component's service life.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In existing technology, electric vehicle front wheel mudguards often adopt a wide and rounded design for aesthetic purposes, with the upper part only fixed to the front fork steering gear by a few bolts. Because the lower part of the mudguard lacks a supporting structure, vibrations during vehicle operation can easily cause abnormal noises from the mudguard, and cracks may occur after long-term use, affecting the riding experience and the lifespan of the component.

[0025] To address these issues, the inventors discovered that the root cause of the noise and cracking lay in the lack of effective support at the bottom of the mudguard. Analysis of the vibration transmission path revealed that traditional fixing methods failed to distribute stress in the cantilever area. Therefore, they proposed incorporating an extended support structure within the mudguard's inner cavity. This multi-point fixing creates mechanical balance, thereby suppressing vibration and enhancing structural stability.

[0026] Therefore, as Figure 1-8 As shown, this utility model provides a mudguard adapter bracket, which includes a bracket body 1. The bracket body 1 is used to install in the inner cavity 21 of the mudguard 2 and is arranged along the longitudinal extension direction of the mudguard 2. The mudguard 2 has a number of mounting points, which are used to install the bracket body 1 in the inner cavity 21 of the mudguard and the front fork steering gear 31.

[0027] The bracket body 1 is the main structure that bears the support function. It can be made of metal rods or composite materials. Its longitudinal extension direction is consistent with the length direction of the mudguard 2, and it is used to cover the suspended area of ​​the mudguard inner cavity 21. The mounting points are positioning structures used to realize mechanical connection. They are bolt holes, and their distribution is determined according to the spatial layout of the mudguard inner cavity 21. They are used to fix the bracket body 1 between the mudguard 2 and the front fork steering gear 31.

[0028] Specifically, the bracket body 1 extends longitudinally along the inner cavity 21 of the mudguard, forming a rigid support frame that runs through the suspended area. Multiple mounting points are located at different positions on the bracket body 1, forming a three-point or more constraint relationship through fixed connections with the fork steering gear 31 and the wall of the inner cavity 21 of the mudguard. When the vehicle vibrates during driving, the bracket body 1 disperses the vibration energy through multi-point fixation, reducing the amplitude of the suspended part of the mudguard 2.

[0029] Compared with existing technologies, traditional solutions rely solely on a few bolts for fixing the upper part of the mudguard 2, resulting in free-end vibration in the suspended area. This invention, by setting a longitudinally extending support body 1 in the inner cavity 21 of the mudguard, combined with multi-point fixing to form distributed support, effectively suppresses the vibration transmission path and eliminates structural fatigue caused by free-end vibration.

[0030] Through the above technical solution, this utility model can enhance the rigid support of the suspended area of ​​the mudguard 2, reduce abnormal noise caused by vibration during riding, and at the same time reduce the risk of cracking of the mudguard 2 by stress dispersion, thus extending the service life of the component.

[0031] Specifically, such as Figure 1-3 As shown, the bracket body 1 includes a first rod 12 and a second rod 13. The first rod 12 and the second rod 13 are spaced apart by a preset distance and are arranged in a fork shape. The first rod 12 and the second rod 13 are both arranged along the longitudinal extension direction of the mudguard 2. The end of the first rod 12 is provided with a first installation point 121, and the end of the second rod 13 is provided with a second installation point 131.

[0032] The fork-shaped arrangement of the first rod 12 and the second rod 13 forms a double-support structure, increasing the contact area with the mudguard 2. Specifically, the first rod 12 and the second rod 13 extend longitudinally along the mudguard 2, forming a double-support structure through the fork-shaped arrangement. Their ends are fixed to the inner cavity 21 of the mudguard via plate-shaped first and second mounting points 131. The two rods are spaced a predetermined distance apart, distributing the supporting force to different areas of the mudguard 2 and preventing stress concentration at a single location. The fork-shaped arrangement allows for multi-point contact between the rods and the inner cavity 21 of the mudguard, reducing the lateral sway of the mudguard 2 during riding. The plate-shaped mounting points enhance stability.

[0033] This embodiment uses a fork-shaped double-bar structure to distribute the supporting force to both sides of the mudguard 2 longitudinally, while using plate-shaped mounting points to increase the connection strength, effectively reducing vibration and deformation caused by excessive cantilever length.

[0034] It should be noted that, as Figure 1-3 As shown, the first mounting point 121 has a plate-like structure, and the angle between it and the first rod 12 is greater than 90 degrees. The second mounting point 131 also has a plate-like structure, and the angle between it and the second rod 13 is greater than 90 degrees.

[0035] An included angle greater than 90 degrees refers to an obtuse angle structure formed at the connection between the plate-like structure and the rod, which can be formed through a bending process. This angle design allows the plate-like structure to extend outward to form a supporting surface, enhancing the constraint on the side wall of the mudguard 2 while also adapting to the curved shape of the inner cavity wall 21 of the mudguard.

[0036] Specifically, in the inner cavity 21 of the mudguard, the plate-like structure at the end of the first rod 12 and the plate-like structure at the end of the second rod 13 extend outward at an obtuse angle to form a connection and fixation with the angular structure 23 of the inner wall of the mudguard 2.

[0037] In addition, such as Figure 1-3 As shown, the support body 1 also includes a hollow plate 11, a first rod 12 and a second rod 13 located at the bottom of the hollow plate 11 and integrally formed with the first rod 12 and the second rod 13, that is, the hollow plate 11, the first rod 12 and the second rod 13 form an approximately H-shaped structure.

[0038] The perforated plate 11 reduces overall weight while maintaining structural strength, and the rods at its bottom form a support frame. Specifically, the perforated plate 11 extends longitudinally along the inner cavity 21 of the mudguard, and its bottom edge is molded into two branching rods. The mounting points at the top of the perforated plate 11 are formed into upward-folding fixing ears by stamping, and are fixed at multiple points with the mounting holes at the top of the mudguard 2 by bolts.

[0039] And the perforated plate 11 has a perforated area 111, such as Figure 1-3 As shown, a third mounting point 112 is provided on the inner wall of the hollow area 111. The third mounting point 112 has a plate-like structure and the included angle between it and the hollow plate 11 is greater than 90 degrees.

[0040] The third installation point 112 is a fixed structure set at the edge of the hollow area 111. Specifically, it can be achieved by bending the edge of the hole outward to form a plate-like protrusion. The stability of the connection between the bracket and the mudguard 2 is improved by increasing the connection point.

[0041] When the bracket body 1 is installed in the inner cavity 21 of the mudguard, the third installation point 112 engages with the pre-set groove on the inner wall of the mudguard 2 to form a multi-point fixation. This structure maintains the longitudinal support force of the bracket body 1 while reducing the amount of material used through the hollow area 111, and disperses the vibration load on the lower part of the mudguard 2 through the third installation point 112.

[0042] See also Figure 1-3 As shown, the top two ends of the hollow plate 11 are provided with a fourth mounting point 113 and a fifth mounting point 114 for installation on the mudguard top plate 22. The fourth mounting point 113 and the fifth mounting point 114 are both plate-shaped structures and are spaced at a preset distance. The included angle between the fourth mounting point 113 and the fifth mounting point and the hollow plate 11 is greater than 90 degrees.

[0043] The fourth installation point 113 and the fifth installation point 114 are fixed connection areas located at both ends of the top of the hollow plate 11. These can be achieved using bent metal sheets. The plate-like structure increases the contact area with the mudguard top plate 22, improving connection stability. An angle greater than 90 degrees forms an obtuse angle between the installation point and the hollow plate 11. This can be achieved by bending the installation point outwards. The obtuse angle structure enhances the support for the mudguard top plate 22, suppresses vibration transmission, and can also adapt to the curved surface structure of the mudguard inner cavity 21.

[0044] During installation, the fourth mounting point 113 and the fifth mounting point 114 are fixed to the mounting holes of the mudguard top plate 22 by bolts or rivets. The obtuse angle structure makes the mounting point and the top plate 22 form a stable triangular support, thereby dispersing the vibration stress generated in the lower suspended area of ​​the mudguard 2 during riding and reducing the risk of structural fatigue.

[0045] like Figure 4-8 As shown, this utility model also proposes a mudguard 2 assembly, including a mudguard 2 and a mudguard adapter bracket. The mudguard adapter bracket is installed in the inner cavity 21 of the mudguard. The inner cavity 21 of the mudguard is provided with an angular structural member 23 adapted to the first mounting point 121 and the second mounting point 131. The top plate 22 of the mudguard is provided with mounting holes adapted to the fourth mounting point 113 and the fifth mounting point 114.

[0046] The angular structural component 23 is a metal or plastic connecting part with a bent shape. Specifically, it can be realized by using L-shaped or U-shaped sheet metal parts. Its bending angle matches the plate-like structure of the installation point to enhance the contact area and fixing strength between the installation point and the inner cavity 21 of the mudguard.

[0047] Specifically, the mudguard adapter bracket is connected to the angled structure 23 of the inner wall of the mudguard cavity 21 via the first mounting point 121 and the second mounting point 131, forming a bottom support. Simultaneously, it is connected to the mounting holes of the top plate 22 of the mudguard via the fourth mounting point 113 and the fifth mounting point 114, forming a top fixation. The third mounting point 112 on the perforated plate 11 further provides auxiliary support in the middle area, allowing the vibration and impact forces experienced by the mudguard 2 during riding to be dispersed and transmitted through multiple mounting points, thereby reducing local stress concentration.

[0048] Unlike existing mudguards 2 which are fixed to the fork steering gear 31 with only 2 to 3 bolts, resulting in a lack of support in the cantilever area, this invention uses an adapter bracket to distribute multiple mounting points in the inner cavity 21 and top of the mudguard, forming a three-dimensional support structure. Furthermore, the way the angular structural component 23 engages with the mounting points avoids the loosening defects of traditional planar bolt connections.

[0049] This utility model further proposes an electric vehicle including a front fork 3 and a mudguard 2 assembly. The front fork 3 includes a fork shank 32 and a front fork steering mechanism 31. The fork shank 32 is mounted on the front fork steering mechanism 31. The top plate 22 of the mudguard is provided with mounting holes for fixing the front fork steering mechanism 31. The mudguard 2 assembly includes a mudguard 2 and a mudguard adapter bracket. The mudguard adapter bracket is installed in the inner cavity 21 of the mudguard. The inner cavity 21 of the mudguard is provided with an angular structural member 23 adapted to the first mounting point 121 and the second mounting point 131. The top plate 22 of the mudguard is provided with mounting holes adapted to the fourth mounting point 113 and the fifth mounting point 114.

[0050] Specifically, the mudguard adapter bracket is fixed to the angled structure 23 of the inner wall of the mudguard cavity 21 via the first mounting point 121 and the second mounting point 131. Simultaneously, the fourth mounting point 113 and the fifth mounting point 114 are connected to the mounting holes of the mudguard top plate 22, forming a two-tiered support structure. The fork steerable 31 is rigidly fixed by bolts passing through the mounting holes of the mudguard top plate 22. The fork steerable 32 is mounted on the fork steerable 31, ensuring a stable force transmission path between the mudguard 2 and the fork 3.
