Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, and particularly relates to a fender device and a bicycle. Background Art

[0002] A fender, such as a fender installed on a bicycle, is usually a metal plate or a plastic plate. On this basis, some fender products will additionally cover an elastic rubber layer on the outer surface of the metal plate or the plastic plate. That is, the metal plate or the plastic plate serves as a plate skeleton, and the elastic rubber layer serves as a covering member covering the outer surface of the plate skeleton, so as to have better hand feeling and quality on the premise of ensuring that the fender has good structural strength and stiffness.

[0003] However, for the existing fender with a covering member, after the covering member is formed on the outer surface of the plate skeleton in a mold, part of the side edges of the plate skeleton are likely to penetrate through the covering member and be exposed, or although the side edges do not penetrate, the thickness of the covering member in the corresponding area is very thin, and the side edges of the plate skeleton are very prominent and conspicuous, resulting in the rejection and scrapping of the product.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the attached drawings).

[0043] A mudguard, such as a mudguard installed on a bicycle, is usually a metal plate or a plastic plate. On this basis, some mudguard products will additionally cover an elastic rubber layer on the outer surface of the metal plate or plastic plate. That is, the metal plate or plastic plate serves as a plate skeleton, and the elastic rubber layer serves as a covering member covering the outer surface of the plate skeleton, so as to have better feel and quality on the premise of ensuring good structural strength and stiffness of the mudguard.

[0044] However, for the existing fender with a covering part, during the production process, it is difficult to control the position accuracy of the side edge of the plate skeleton because it is not restricted in the mold. As a result, after the covering part is formed on the outer surface of the plate skeleton in the mold, part of the side edge of the plate skeleton is likely to penetrate through the covering part and be exposed outside, or although part of the side edge does not penetrate, it will make the thickness of the covering part very thin in the corresponding area, and cause the side edge of the plate skeleton, which is of a different color from the covering part, to be very prominent and conspicuous. In particular, when the covering part uses bright colors, such as bright yellow, bright blue, etc., the dark plate skeleton will have part of its side edge not centered and fixed inside the covering part, making this part of the dark side edge visible to the naked eye (either directly exposed outside or not exposed but conspicuous), and resulting in the rejection and scrapping of the product.

[0045] In view of this, the present utility model provides a fender and a fender device having the fender, and the fender can solve the above technical problems, that is, it can solve the problem of product rejection caused by the exposure or conspicuousness of the side edge of the plate skeleton.

[0046] Please refer to Figures 1 to 5 , in which, Figure 3 and Figure 4 The outer contour of the plate skeleton 11 located inside the covering part 12 is shown by a dotted line. In an embodiment of the fender 10 of the present utility model, the fender 10 includes a plate skeleton 11 and a covering part 12. The plate skeleton 11 extends in the first direction and has two first side edges 11a located on both sides of the first direction and two second side edges 11b located at both ends of the first direction; the covering part 12 includes a covering layer 121 and a rib 124. The covering layer 121 covers the outer surface of the plate skeleton 11, and the rib 124 protrudes from the outer surface of the covering layer 121 at least corresponding to the first side edge 11a, and makes the projection area of the rib 124 towards the front projection of the plate skeleton 11 cover the first side edge 11a.

[0047] According to the technical solution of the present utility model, by providing the rib 124 in the area of the covering layer 121 corresponding to the side edge (the first side edge 11a) of the plate skeleton 11, the side edge of the plate skeleton 11 is covered by both the covering layer 121 and the rib 124 at the same time. Even if the first side edge 11a of the plate skeleton 11 fails to be centered and fixed in the covering layer 121 due to inaccurate position in the mold, it will be covered by the rib 124 outside the covering layer 121, thereby improving or even avoiding the problem of the exposure or conspicuousness of the side edge of the plate skeleton 11 and increasing the production yield rate of the fender 10.

[0048] Of course, the above technical problem can also be solved by thickening the entire wrapping member 12. For example, assuming that the original thickness of the area of the wrapping member 12 located on the upper or lower side of the plate skeleton 11 is 1.5 mm, and when there is still a problem of the side edge of the plate skeleton 11 being exposed or conspicuous at this thickness, it can be considered to increase the thickness to 2 mm or even 2.5 mm to solve this problem. However, obviously, this method of overall thickening not only significantly increases the amount of raw material of the wrapping member 12 required for a single fender 10, thereby increasing the manufacturing cost of the fender 10, but also increases the weight of the fender 10. That is to say, compared with the solution of overall thickening the wrapping member 12, the fender 10 of the technical solution of the present utility model not only uses less raw material of the wrapping member 12, but also the manufactured fender 10 has a lighter weight.

[0049] Therefore, for the fender 10 of the present utility model, by locally thickening the wrapping member 12, it is possible to improve the problem of the side edge of the plate skeleton 11 being exposed or conspicuous, and at the same time avoid a significant increase in the overall thickness and material consumption of the wrapping member 12, thereby facilitating the control of the manufacturing cost and weight of the fender 10.

[0050] It should be noted that the positive projection towards the plate skeleton 11 means that each structural point of the convex rib 124 is projected onto the plate surface of the plate skeleton 11 along the direction perpendicular to the plate surface (upper surface or lower surface) of the plate skeleton 11. For example, when the plate surface of the plate skeleton 11 is a cylindrical surface with a central angle less than 360°, such as a cylindrical surface with a central angle of 45°, the area formed by the intersection points of the perpendicular connection lines between each structural point of the convex rib 124 and the central axis of the cylindrical surface and the cylindrical surface is the projection area obtained by the positive projection towards the plate skeleton 11.

[0051] In some embodiments, optionally, the convex ribs 124 are provided on the upper and lower surfaces of the wrapping layer 121. That is to say, the convex ribs 124 are provided on both the upper and lower surfaces of the wrapping layer 121. In this way, regardless of whether the side edge of the plate skeleton 11 is offset upward or downward in the mold, the areas with relatively thin thickness on the upper or lower surface of the wrapping layer 121 caused by the position offset can be covered by the convex ribs 124, thereby more comprehensively avoiding the problem of the side edge of the plate skeleton 11 being exposed or conspicuous. Of course, in other embodiments, the convex ribs 124 may also be provided only on the upper surface of the wrapping layer 121, or the convex ribs 124 may be provided only on the lower surface of the wrapping layer 121.

[0052] It should be noted that the upper surface of the coating layer 121 refers to the surface of the coating layer 121 facing upward when the fender 10 is applied to a vehicle such as a bicycle. Correspondingly, the lower surface of the coating layer 121 refers to the surface of the coating layer 121 facing downward when the fender 10 is applied to a vehicle such as a bicycle. That is to say, the orientation definition in the embodiments of the present invention defaults to the orientation definition when the fender 10 is installed and applied to a vehicle. For example, the up and down directions of the fender 10 refer to the up and down orientations after it is installed on the vehicle. If other definitions are adopted, it will be specifically stated. Among them, the first direction is Figure 1 and Figure 3 the front and rear directions shown.

[0053] It is worth mentioning that the technical solution of the present invention can be applied not only to bicycles, but also to vehicles such as motorcycles, balance bikes and unicycles. In addition, when applied to a bicycle, it can specifically be the front fender 10 or the rear fender 10. For the convenience of understanding, the following will take a bicycle as an example for explanation.

[0054] There are various installation methods of the fender 10 on the bicycle. For example, please refer to Figure 9 , in an embodiment of the fender device, the fender device includes a fender 10 and a mounting bracket 20. The mounting bracket 20 is provided on the fender 10 and is used for mounting with the vehicle frame. Optionally, the mounting bracket 20 is separately provided from the fender 10 and is installed and fixed by fasteners. For example, one end of the mounting bracket 20 can be locked to one end of the fender 10 by a bolt-nut pair, and then the other end of the mounting bracket 20 can be locked to the vehicle frame by another bolt-nut pair.

[0055] Of course, in some other embodiments, the fender 10 and the mounting bracket 20 can also be integrally formed or formed as an integral setting. In other embodiments, the mounting bracket 20 can also be not provided, and the fender 10 is directly mounted on the vehicle frame of the bicycle. For example, the fender 10 is provided with mounting holes, and the mounting holes are mounted on the vehicle frame by bolt-nut pairs.

[0056] Please refer to Figure 1 and Figure 9 , wherein, Figure 1 the fender 10 shown is in an unfolded state, Figure 9The mudguard 10 is shown in a retracted state. Optionally, the mudguard 10 can be rolled along a first direction and has an unfolded state and a retracted state. The mudguard 10 in the unfolded state is in a long strip shape, and the mudguard 10 in the retracted state is in a cylindrical shape. In this way, the mudguard 10 has two usage forms (i.e., the unfolded state and the retracted state) for the user to choose, which can facilitate the user to change the usage form of the mudguard 10 according to the riding scene to enrich the functionality and fun of the product. Specifically, when the user rides on a road with accumulated water or snow, the mudguard 10 can be unfolded along the first direction to the unfolded state to give full play to the good mud-blocking effect of the mudguard 10 and avoid splashing the mud and water brought by the rotation of the front and rear wheels; when the user rides on a dry road, the mudguard 10 can be rolled along the first direction to the retracted state, which can not only reduce the wind resistance and the abnormal noise caused by the shaking of the mudguard 10, but also make the bicycle sporty.

[0057] See also Figure 5 , Figure 5 The mudguard shown is in an unfolded state. Optionally, the plate frame 11 is configured as an elastic plate-like structure. When the mudguard 10 is in an unfolded state, the cross section of the plate frame 11 perpendicular to the first direction extends along an arc, and the upper surface of the plate frame 11 forms a convex arc surface and the lower surface of the plate frame 11 forms a concave arc surface; when the mudguard 10 is in a retracted state, the cross section of the plate frame 11 perpendicular to the first direction extends along a straight line. Specifically, when the plate frame 11 is in a retracted state, it can be maintained in the retracted state by relying on its own elastic potential energy along the first direction; when the user applies a force to deform the plate frame 11 to the unfolded state, the plate frame 11 has elastic potential energy perpendicular to the first direction (i.e., along the plane where the cross section of the plate frame 11 is located). Since the cross section of the plate frame 11 extends along an arc at this time, the structural characteristics can overcome the tendency of the plate frame 11 to curl along the first direction, so that the plate frame 11 is maintained in the unfolded state.

[0058] When the user applies force to the mudguard 10 in the unfolded state, such as tapping the upper side of the mudguard 10 with a finger, so that the cross section of the plate frame 11 at a certain position becomes roughly rectangular (i.e., the cross section shape extends along a straight line), the plate frame 11 will curl along the first direction. In this way, the operation required for the mudguard 10 to change from the unfolded state to the retracted state is extremely simple, that is, it is sufficient to tap or bend any position of the mudguard 10, and the operation required for the mudguard 10 to change from the retracted state to the unfolded state is also very simple, that is, it is only necessary to overcome the elastic potential energy of the mudguard 10 along the first direction to unfold it, and the mudguard 10 itself can remain in the unfolded state unchanged. It can be seen that the mudguard 10 of the utility model is easy to operate and full of fun, and the use state of the mudguard 10 can be changed and maintained without the help of additional fixing structures and tools.

[0059] Optionally, the plate skeleton 11 is configured as an elastic steel sheet, such as a manganese steel sheet, preferably a steel sheet made of 65Mn material. Further optionally, the radius of the circle where the concave arc surface of the steel sheet is located ranges from 43 mm to 50 mm, which can effectively avoid the problem that the fender 10 accidentally curls under the influence of the bicycle jitter in the unfolded state, and can ensure that the body of the fender 10 can be smoothly curled from the unfolded state when not in use.

[0060] Please refer to Figure 5 or Figure 6 , in the embodiment where the fender 10 can be curled and has an unfolded state and a retracted state, optionally, the convex ribs 124 are only provided on the upper surface of the coating layer 121. Assuming that the upper surface of the plate skeleton 11 is arranged adjacent to the lower cavity surface of the mold, it can be understood that since the cross-sectional shape of the elastic plate skeleton 11 is arc-shaped, the first side edge 11a of the plate skeleton 11 has a tendency to move away from each other, which is manifested as the first side edge 11a having a tendency to approach the lower cavity surface of the mold in the mold, so that the first side edge 11a is more likely to be exposed or stand out from the upper surface of the coating layer 121. That is, in this embodiment, the appearance quality problem of the fender 10 basically appears on the upper surface of the coating layer 121. Therefore, in this embodiment, the convex ribs 124 are specifically provided only on the upper surface of the coating layer 121, which can not only solve the problem of this appearance quality defect, but also save the structure of the convex ribs 124, thereby saving the raw material usage of the coating part 12. Of course, in other embodiments, the upper surface and the lower surface of the coating layer 121 may both be convexly provided with convex ribs 124.

[0061] Please refer to Figure 1 and Figure 3 , optionally, the convex ribs 124 are also correspondingly provided for at least part of the second side edge 11b, and the projection area of the convex ribs 124 towards the orthographic projection of the plate skeleton 11 covers at least part of the second side edge 11b. In this way, the convex ribs 124 also cover the second side edge 11b, which can further reduce the probability of the side edge of the plate skeleton 11 being exposed or standing out. Of course, in other embodiments, the convex ribs 124 may also be provided only corresponding to the first side edge 11a of the plate skeleton 11.

[0062] Please refer to Figure 3 and Figure 7 , in some embodiments, a positioning structure is provided in the middle of the second side edge 11b, and the convex ribs 124 include two sub-convex ribs 125 spaced apart along a direction intersecting the first direction. The sub-convex ribs 125 include an intersecting first rib segment 126 and a second rib segment 127. The first rib segment 126 extends along the first direction, and the second rib segment 127 extends along the width direction of the plate skeleton 11. Adjacent two second rib segments 127 are spaced apart at the position corresponding to the positioning structure.

[0063] Specifically, please refer to Figure 3, in the first embodiment, the sub-rib 125 includes an intersecting first rib segment 126 and a second rib segment 127, and the second rib segment 127 covers a part of the second side edge 11b. Please refer to Figure 7 , in the third embodiment, the sub-rib 125 includes an intersecting first rib segment 126 and a second rib segment 127, and the second rib segment 127 covers the entire second side edge 11b.

[0064] Please refer to Figure 2 , optionally, the positioning structure is configured as a positioning hole 111, and the inner cavity of the mold is provided with a positioning stud corresponding to the positioning hole 111. The positioning stud is inserted into the positioning hole 111 to restrict the lateral and vertical offsets of the plate skeleton 11. It can be understood that the area where the central axis of the plate skeleton 11 extends in the first direction is itself a region with a relatively small elastic deformation amount. By further cooperating the positioning hole 111 with the positioning stud, its position accuracy is relatively high, so that the position accuracy of the middle part of the second side edge 11b is higher than that of its two ends. Therefore, it is not necessary to provide a rib 124 in the middle part of the second side edge 11b. Secondly, the rib 124 is interrupted by making an avoidance corresponding to the positioning structure, which can also avoid the rib 124 affecting the positioning hole 111 and the positioning stud during the production process.

[0065] Please refer to Figure 8 , in the fourth embodiment, the sub-rib 125 only includes a first rib segment 126 extending in the first direction, and the second rib segment 127 is not provided. At this time, the first rib segment 126 can also cover a part of the second side edge 11b. It should be noted that Figure 7 and Figure 8 The outer contour of the plate skeleton 11 located inside the covering member 12 is shown by a dotted line.

[0066] Of course, in some other embodiments, the rib 124 can also be arranged in a continuous annular structure and is provided corresponding to the first side edge 11a and the second side edge 11b. That is, the covering layer 121 is provided with a complete circle of ribs 124 corresponding to all the side edges of the steel sheet (i.e., the first side edge 11a and the second side edge 11b). At this time, regardless of whether the steel sheet is provided with a positioning structure, the rib 124 can basically cover the side edge of the steel sheet.

[0067] In other embodiments, the positioning structure can also be a positioning groove, and the positioning stud of the mold is inserted into the positioning groove; or, the positioning structure is configured as a positioning stud, and correspondingly, the inner cavity of the mold is provided with a positioning hole 111 for inserting the positioning stud.

[0068] Please refer to Figure 5, optionally, in the width direction of the fender 10, the first side edge 11a and the second side edge 11b are located in the middle of the projection area of the rib 124 projected onto the plate skeleton 11. That is, the peripheral side edge of the plate skeleton 11 can either be centered on the center line of the projection area of the rib 124 or be slightly to the left or slightly to the right of the center line of the projection area of the rib 124. In this way, the rib 124 can more comprehensively cover the peripheral side edge of the plate skeleton 11. Of course, in some other embodiments, it can also be that in the width direction of the fender 10, the peripheral side edge of the plate skeleton 11 is located inside the center line of the projection area of the rib 124. That is, more area of the projection area of the rib 124 is located on the side of the peripheral side edge of the plate skeleton 11 away from the center point of the plate skeleton 11. In other embodiments, it can also be that only the first side edge 11a or the second side edge 11b is located in the middle of the projection area of the rib 124 projected onto the plate skeleton 11 in the front projection direction.

[0069] It should be noted that the width direction of the plate skeleton 11 and the fender 10 is the Figures 1 to 5 left - right direction in the illustrated embodiment.

[0070] Please refer to Figure 5 , optionally, the value range of the protruding height H of the rib 124 is from 0.1 mm to 5 mm. That is, the protruding height of the rib 124 is greater than or equal to 0.1 mm and less than or equal to 5 mm. For example, the value can be 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.5 mm, 3 mm, or 4 mm, etc. It can be understood that if the value of the protruding height of the rib 124 is too small, the covering effect of the rib 124 on the side edge of the plate skeleton 11 is limited. If the value is too large, it will not only affect the elastic deformation of the plate skeleton 11, make the curling and unfolding of the fender 10 less smooth and easy, but also increase the process difficulty, lead to a decrease in the yield rate, and increase the manufacturing cost of the fender 10.

[0071] Preferably, the value range of the protruding height H of the rib 124 is from 0.5 mm to 1 mm. For example, the value can be 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm. In this way, the rib 124 with a height within this range can not only have a good covering effect on the side edge of the plate skeleton 11 but also not significantly affect the elastic deformation of the plate skeleton 11.

[0072] In some other embodiments, the protruding height H of the rib 124 ranges from 2.5 mm to 5 mm, and the fender device further includes a light-emitting strip (not shown in the drawings) at least partially embedded in the rib 124. In this way, by adding the light-emitting strip, the functions of the fender device can be enriched. The light-emitting strip can not only serve as a lighting warning, but also act as an ambient light and enhance the fun of cycling. Secondly, using the relatively thick rib 124 to install the light-emitting strip can not only improve the installation reliability of the light-emitting strip, but also avoid the design of additional installation structures for the fender for the light-emitting strip, thereby simplifying the structure of the fender 10. That is to say, the rib 124 in this embodiment has two functions at the same time. One is to cover the side of the cover plate frame 11, and the other is to serve as the installation structure of the light-emitting strip.

[0073] Optionally, the light-emitting strip is configured as a light guide strip, and the fender device further includes a main control board (not shown in the drawings) and a light source (not shown in the drawings) provided at the end face of the light guide strip. The light source is electrically connected to the main control board and irradiates the light guide strip. In this way, the structure is simple and the manufacturing cost is low. Of course, in other embodiments, the light-emitting strip can also be in the structure of an LED strip light, etc.

[0074] It can be understood that the main control board and the light source can be provided on the mounting bracket 20 or the fender 10. The light source can be an LED lamp bead or a laser. The present application does not make specific limitations on this, as long as it can inject light beams into the light guide strip to make the whole light guide strip emit light.

[0075] Optionally, in the width direction of the fender 10, the width L of the rib 124 ranges from 3 mm to 20 mm. That is to say, the width L of the rib 124 is greater than or equal to 3 mm and less than or equal to 20 mm. It can be understood that if the width of the rib 124 is too small, the side edge of the cover plate frame 11 cannot be fully covered; if the width of the rib 124 is too large, the weight and manufacturing amount of the covering member 12 will be significantly increased. Preferably, the width L of the rib 124 ranges from 5 mm to 10 mm, for example, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm. In this way, the rib 124 with a width within this range can not only have a good covering effect on the side edge of the plate frame 11, but also will not significantly increase the weight and manufacturing amount of the covering member 12.

[0076] Please refer to Figure 5 , optionally, in the first embodiment, the cross-sectional shape of the rib 124 perpendicular to the first direction is a polygon or a quasi-polygon, such as a triangle, a rectangle or a hexagon, etc. In this way, the structure is simple and convenient for production and manufacturing. At the same time, the external shape characteristics of the rib 124 are obvious and convenient for identification.

[0077] Please refer to Figure 6, in the second embodiment, the outer surface of the rib 124 is configured as a cylindrical surface with a central angle less than 360°, and the cylindrical surface is smoothly transitioned with the outer surface of the coating layer 121. In this way, the structure is simple and convenient for production and manufacturing. Secondly, the arc outer surface of the rib 124 is smoothly transitioned with the outer surface of the coating layer 121, which can not only avoid the stress concentration problem at the intersection of the rib 124 and the coating layer 121, thereby improving the manufacturing yield and service life of the coated part 12, but also make the external shape characteristics of the rib 124 not obvious and not make the structure of the rib 124 appear abrupt.

[0078] Please refer to Figure 5 , optionally, the coating layer 121 includes a first coating layer 122 provided on the upper surface of the plate skeleton 11 and a second coating layer 123 provided on the lower surface of the plate skeleton 11. The peripheries of the first coating layer 122 and the second coating layer 123 are connected as a whole and cover the side edges of the plate skeleton 11; the thickness of the plate skeleton 11 ranges from 0.1 mm to 0.3 mm, the thickness of the first coating layer 122 ranges from 0.4 mm to 1.5 mm, and the thickness of the second coating layer 123 is 0.4 mm to 1.5 mm. For example, in one embodiment, the thickness of the plate skeleton 11 is 0.2 mm, the thicknesses of the first coating layer 122 and the second coating layer 123 are both 1.2 mm, and the height of the rib 124 is 0.6 mm.

[0079] In this way, the first coating layer 122 and the second coating layer 123 can completely cover the outer surface of the plate skeleton 11, which can not only protect the plate skeleton 11 and improve the feel and texture of the fender 10, but also avoid the problem of the sharp edges of the plate skeleton 11 cutting hands. Of course, in other embodiments, only the first coating layer 122 or the second coating layer 123 can also be provided.

[0080] Please refer to Figure 5 , optionally, the rib 124 and the coating layer 121 are integrally formed, and the material of the coated part 12 is configured as silicone or rubber. In this way, the structure is simple and easy to implement. Of course, in other embodiments, the rib 124 and the coating layer 121 can also be separately provided and then fixed together by means of bonding, hot pressing, etc. The material of the coated part 12 can also be other as long as the coated part 12 has elasticity and good weather resistance.

[0081] Please refer to Figure 5, optionally, the width D of the coating layer 121 ranges from 60 mm to 100 mm, and the width d of the plate skeleton 11 ranges from 45 mm to 55 mm. For example, in one embodiment, the width D of the coating layer 121 is 70 mm, the width d of the plate skeleton 11 is 50 mm, the width of the rib 124 is 6 mm, and the plate skeleton 11 is centered on the horizontal plane; at this time, the interval between the periphery of the coating layer 121 and the periphery of the plate skeleton 11 is 10 mm, and the interval between the outer edge of the rib 124 and the periphery of the coating layer 121 is 7 mm. In this way, the wide coating layer 121 extends a large area beyond the plate skeleton 11 in the transverse direction. The peripheral edge of the coating layer 121 is like a wide brim, which can better block mud and water, and can also control the weight and cost of the plate skeleton 11.

[0082] Please refer to Figure 5 , optionally, the thickness at the joint of the peripheries of the first coating layer 122 and the second coating layer 123 ranges from 0.9 mm to 3.2 mm. For example, the thickness value can be 2.3 mm, 2.5 mm, 2.7 mm, etc. Further optionally, the thickness at the joint of the first coating layer 122 and the second coating layer 123 gradually decreases outward. That is, in the width direction of the mudguard 10, the thickness in the middle region from the center line of the mudguard 10 to the side of the plate skeleton 11 is evenly distributed, and then the thickness in the side edge region from the side of the plate skeleton 11 to the side of the coating layer 121 gradually decreases. That is, the thickness in the brim region gradually becomes smaller outward. In this way, it is beneficial to reduce the thickness and weight of the brim to avoid the interference and influence of the brim structure on the curling and unfolding of the mudguard 10.

[0083] Of course, in other embodiments, it can also be that the thickness at the joint of the first coating layer 122 and the second coating layer 123 is evenly distributed. It can be understood that in the embodiment where the thickness of the mudguard 10 is evenly distributed, except for the region where the rib 124 is located, the total thickness of the remaining regions of the mudguard 10 ranges from 0.9 mm to 3.2 mm.

[0084] In other embodiments, the width D of the coating layer 121 can also be other values, such as 65 mm, 80 mm, 85 mm or 90 mm. It can be understood that the larger the width of the coating layer 121, the more beneficial it is to block mud and water. However, in order to enable the mudguard 10 to have good curling deformation ability, the width of the coating layer 121 should not be set too large.
