Description

Technical Field

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

[0002] When riding a bicycle and encountering a slippery road, the fender can effectively block the mud and water splashed by the wheels, ensuring that the user and the vehicle are clean and tidy. At present, fenders are equipped with reflective structures, such as reflective strips and reflective films. If the ambient light is insufficient or the incident angle of the ambient light is not good, the reflective effect of the reflective structure is poor, which leads to a weak warning effect and is not conducive to riding safety. For example, if the street light is slightly insufficient, when the front light of a motor vehicle is dim or malfunctions, the light reflected by the reflective structure on the fender is also relatively weak, and it cannot ensure that the ambient light and the front light of the motor vehicle can directly hit the reflective structure to make it bright. The driver cannot identify the position of the bicycle well, which is prone to traffic accidents. Utility Model Content

[0040] The utility model provides a fender device 10 .

[0041] See also Figures 1 to 3 In one embodiment of the utility model, the fender device 10 is applied to a bicycle, and the fender device 10 includes a fender 100 and a laser module 200. The fender 100 includes a plate frame 110 and a cladding layer 120 coated on the outer surface of the plate frame 110, and the cladding layer 120 is a transparent or translucent material; the laser module 200 is arranged at one end of the fender 100, and the light emitted by the laser module 200 can be injected into the cladding layer 120 and can be scattered in the cladding layer 120, so that the cladding layer 120 forms a light-emitting area.

[0042] In addition to being applied to bicycles, the technical solution of the utility model can also be applied to vehicles such as motorcycles, balance bikes and unicycles. In addition, when applied to bicycles, the technical solution can be a front fender 100 or a rear fender 100. For the convenience of writing, the following will be explained by taking a bicycle as an example.

[0043] The technical solution of the utility model realizes the purpose of warning the vehicle behind when riding at night by setting a laser module 200 at one end of the fender 100. The fender 100 is used to shield the muddy water splashed from the ground, and the luminous area formed by the laser module 200 on the fender 100 can play a good warning role.

[0044] Specifically, the fender 100 includes a plate frame 110 and a cladding layer 120, wherein the plate frame 110 provides support and shape for the fender 100. The cladding layer 120 covers the outside of the plate frame 110 and is made of a transparent or translucent material, such as plastic, silicone, rubber or other high molecular polymer materials. The laser module 200 is installed at one end of the fender 100 as a light source, and can be installed on the fender 100 or on the outside of the end of the fender 100. The laser module 200 emits light into the cladding layer 120. Since the cladding layer 120 is a transparent or translucent material, the light will be reflected and scattered multiple times inside the cladding layer 120, and finally uniformly emitted from the surface of the cladding layer 120, so that at least part of the entire cladding layer 120 is illuminated, which improves visibility at night or in low light conditions, and can play a luminous warning role, thereby improving riding safety.

[0045] It should be noted that the outer surface of the plate frame 110 includes the upper surface, the lower surface and the side edge between the upper and lower surfaces of the plate frame 110, wherein the upper surface of the plate frame 110 refers to the side facing the wheel when the fender 100 is installed on the vehicle body, and correspondingly, the lower surface of the plate frame 110 refers to the side of the fender 100 facing away from the wheel.

[0046] The technical solution of the utility model is to set a laser module 200 at one end of the fender 100, so that the light emitted by the laser module 200 is scattered inside the coating layer 120 of the fender 100 to form a luminous area with a warning function, so as to improve visibility at night or in low light conditions, thereby improving riding safety.

[0047] In one embodiment, see Figure 3 and Figure 4 The covering layer 120 includes a first covering layer 121 disposed on the upper surface of the plate frame 110, and a second covering layer 122 disposed on the lower surface of the plate frame 110. The peripheries of the first covering layer 121 and the second covering layer 122 are connected as a whole and cover the side edges of the plate frame 110. The light emitted by the laser module 200 can be incident on the first covering layer 121.

[0048] The material of the plate frame 110 is configured as metal or elastic metal. The plate frame 110 is relatively thin, and the thickness of the plate frame 110 is 0.1mm to 0.3mm. At this time, the edge of the plate frame 110 is relatively sharp, and the user is at risk of being scratched. The coating layer 120 can prevent the user from being scratched by the plate frame 110 when contacting the fender 100. The coating layer 120 of transparent or translucent material provides a basis for the scattering of light from the laser module 200. The light emitted by the laser module 200 can be injected into the first coating layer 121, that is, the upper surface of the fender 100 can emit light, so as to improve visibility at night or in low light conditions, and can play a luminous warning role, thereby improving riding safety.

[0049] In another embodiment, the light emitted by the laser module 200 can be injected into the second cladding layer 122 .

[0050] In another embodiment, the light emitted by the laser module 200 can enter the first cladding layer 121 and the second cladding layer 122. That is, both the upper and lower surfaces of the fender 100 may emit light, and when the lower surface emits light, the wheels can be illuminated, which can also improve the driving safety and playability of the bicycle.

[0051] The covering layer 120 covers the entire outer surface of the plate frame 110 to provide better protection. The covering layer 120 completely wraps the plate frame 110. At this time, the plate frame 110 will not react chemically with the outside world, which can effectively improve the weather resistance of the mudguard 100 and avoid defects such as easy aging, fading, and difficulty in cleaning mud.

[0052] In other embodiments, the side edge of the plate frame 110 may not be covered by the covering layer 120 , and a thicker coating may be applied to the side edge of the plate frame 110 to increase the thickness of the side edge of the fender 100 .

[0053] In one embodiment, see Figure 2 and Figure 3 The fender 100 has a first end 101 and a second end 102 that are opposite to each other in the length direction, the first cladding layer 121 is provided with a mounting groove 123 at the first end 101, the laser module 200 includes a laser, the laser is installed in the mounting groove 123, and the light emitted by the laser is emitted toward the groove side of the mounting groove 123 close to the second end 102, and is emitted toward the second end 102.

[0054] The fender 100 has a first end 101 and a second end 102 in the length direction, and the first end 101 may be mounted on the vehicle frame, or the second end 102 may be mounted on the vehicle frame. That is, the light of the laser module 200 may be emitted from the front end to the rear end of the fender 100, or from the rear end to the front end of the fender 100.

[0055] The mounting groove 123 is disposed at the first end 101 of the first cladding layer 121 and is used to mount the laser of the laser module 200 .

[0056] The light emitted by the laser is shot into the first cladding layer 121 from the side of the mounting groove 123 near the second end 102. Through reflection and scattering, the light begins to propagate along the length direction of the fender 100 toward the second end 102. The light is reflected and scattered multiple times inside the first cladding layer 121, and finally evenly radiates from the surface of the first cladding layer 121 to form a luminous area. At night or in low-light environments, the luminous fender 100 can significantly improve its visibility, thereby improving riding safety. The mounting groove 123 can ensure that the laser is stably installed and will not loosen or fall off due to vibration, thereby avoiding displacement or damage of the laser due to bumps during riding. Furthermore, the laser can be fixed by fixing methods such as tape winding and fastener 330 locking to ensure stable installation of the laser.

[0057] In another embodiment, the second cladding layer 122 is provided with a mounting groove 123 at the first end 101 , so that the light emitted by the laser module 200 can be injected into the second cladding layer 122 .

[0058] In another embodiment, the first cladding layer 121 and the second cladding layer 122 are both provided with a mounting groove 123 at the first end 101 , so that the light emitted by the laser module 200 can be incident into the corresponding first cladding layer 121 and the second cladding layer 122 .

[0059] In one embodiment, see Figure 2 and Figure 3 The mounting groove 123 extends along the width direction of the cladding layer 120 , and a plurality of lasers are arranged at intervals along the extending direction of the mounting groove 123 .

[0060] The light emitted by each laser is reflected and scattered multiple times inside the cladding layer 120, and finally evenly radiates from the surface of the cladding layer 120 to form a light-emitting area. Multiple lasers are arranged at intervals along the extension direction of the mounting groove 123, that is, multiple lasers are arranged at intervals along the width direction of the cladding layer 120, so that the light emitted by the entire laser module 200 is more evenly distributed on the surface of the cladding layer 120, thereby improving the overall brightness and visibility of the light-emitting area.

[0061] In another embodiment, a plurality of mounting grooves 123 may be provided. The plurality of mounting grooves 123 are arranged at intervals along the width direction of the cladding layer 120 , and at least one laser is installed in each mounting groove 123 .

[0062] In one embodiment, the thickness of the first coating layer 121 and / or the second coating layer 122 is not less than 3 mm, and the depth of the installation groove 123 is not less than 3 mm.

[0063] Taking a conventional small laser on the market as an example, the end face diameter of the laser is 4mm, and the height difference from the laser light emitting center line to the bottom surface of the mounting groove 123 is 2mm, as long as it is guaranteed that the laser light can be injected. In this embodiment, by setting the thickness of the first cladding layer 121 and the second cladding layer 122 to be not less than 3mm, a design margin of 1mm is reserved to reduce the risk that the laser light cannot be injected into the cladding layer 120 due to installation errors or the shaking of the fender 100. It can be understood that when the thickness of the first cladding layer 121 and the second cladding layer 122 is the same as the groove depth of the mounting groove 123, it means that the groove bottom surface of the mounting groove 123 is the outer surface of the plate frame 110.

[0064] In one embodiment, the thickness of the plate skeleton 110 ranges from 0.1 mm to 0.3 mm.

[0065] The first coating layer 121 and the second coating layer 122 can fully cover the outer surface of the plate frame 110, which can not only protect the plate frame 110 and improve the feel and texture of the fender 100, but also avoid the problem of the sharp edge of the plate frame 110 cutting the hand. Of course, in other embodiments, only the first coating layer 121 or the second coating layer 122 can be provided. In one embodiment, the thickness of the plate frame 110 is 0.2 mm, which can ensure that the plate frame 110 has a certain strength and realize the thinness of the plate frame 110.

[0066] In one embodiment, see Figures 5 to 7 The fender 100 has a first end 101 and a second end 102 that are opposite to each other in the length direction. The fender device 10 also includes a control box 300 having an installation cavity. The first end 101 of the fender 100 is inserted into the installation cavity. The laser module 200 is arranged in the installation cavity and is located on a side of the end surface of the first end 101 away from the second end 102. The light emitted by the laser module 200 is emitted toward the end surface of the first end 101 and toward the second end 102.

[0067] The control box 300 has a mounting cavity for accommodating the first end 101 of the fender 100 and the laser module 200 .

[0068] Different from the solution in which the laser module 200 is installed on the cladding layer 120 in the previous embodiment, in the present embodiment, the laser module 200 is arranged in the installation cavity and is located on the side of the end surface of the first end 101 of the fender 100 away from the second end 102, that is, the laser module 200 is not arranged on the fender 100, but is located outside the end surface of the first end 101 of the fender 100. The light emitted by the laser module 200 enters the end surface of the first end 101 of the fender 100 and is emitted toward the second end 102. The light is reflected and scattered multiple times inside the cladding layer 120 of the fender 100 along the length direction of the fender 100, and is evenly emitted from the surface of the cladding layer 120 to form a luminous area, so that at night or in a low-light environment, the luminous fender 100 can significantly improve the visibility of the fender 100, thereby improving riding safety.

[0069] The laser module 200 should be accurately installed in the installation cavity and ensure that the light can be correctly directed to the end surface of the first end 101 of the fender 100 and propagate along the length direction. Since the position of the laser in the vertical direction is adjustable, as long as the laser light can be directed into the cladding layer 120, the thickness of the cladding layer 120 does not need to consider the diameter of the light-emitting end surface of the laser, so the thickness of the cladding layer 120 can be reduced to achieve a thinner cladding layer 120 and reduce production costs.

[0070] The control box 300 includes a first box body 310, a second box body 320 and at least one fastener 330. The first box body 310 and the second box body 320 enclose an installation cavity. The first box body 310, the second box body 320 and the fender 100 are assembled as a whole through at least one fastener 330. The laser module 200 is installed on the first box body 310 or the second box body 320 through at least one fastener 330.

[0071] In one embodiment, see Figure 1 The fender device 10 further includes a mounting bracket 400 , one end of which is connected to the control box 300 , and the other end of which is used to be mounted on a bicycle frame.

[0072] The mounting bracket 400 can be connected to the outer surface of the control box 300 by welding, fixing with a fastener 330, etc., or can be inserted into the mounting cavity and locked by the fastener 330. The mounting bracket 400 allows the fender device 10 to be easily installed on the bicycle, and the mounting bracket 400 is strong enough to withstand vibration during riding, ensuring that the fender 100 and the control box 300 can be stably installed on the bicycle.

[0073] In another embodiment, one end of the mounting bracket 400 is disposed on the outer surface of the control box 300 and connected to the first end 101 of the fender 100 , and the other end of the mounting bracket 400 is used to be mounted on the frame of the bicycle.

[0074] In yet another embodiment, see Figures 6 to 8 , one end of the mounting bracket 400 is inserted into the mounting cavity and connected to the first end 101 of the mudguard 100, and the other end of the mounting bracket 400 is used to be mounted on the frame of the bicycle. That is, the connection parts between the mudguard 100 and the mounting bracket 400 are all arranged in the mounting cavity. That is, the mudguard 100 has a relative mounting end and a free end, the mounting end is the end of the mudguard 100 connected to the mounting bracket 400, that is, the first end 101; the free end is the end of the mudguard 100 away from the mounting bracket 400, that is, the second end 102. Since the mudguard 100 is installed on the vehicle body and is often in an outdoor environment, and the laser module 200 and other electronic devices that need to be waterproof and moisture-proof (such as the main control board, power supply module, etc.) need to have a waterproof and moisture-proof placement space, the laser module 200 and other electronic devices and the wires connecting these electronic devices are all arranged in the mounting cavity of the control box 300.

[0075] For easy installation, the control box 300, the fender 100 and the mounting bracket 400 share a fastener 330 for assembly and fixing. In this embodiment, there are at least two fasteners 330 configured as screws, and the first box body 310, the second box body 320, the fender 100 and the mounting bracket 400 are provided with mounting holes at corresponding positions, and two screws pass through the mounting holes to assemble the first box body 310, the second box body 320, the fender 100 and the mounting bracket 400 into one. In other embodiments, the fender 100 can be first fixedly connected to the mounting bracket 400, and then assembled with the first box body 310 and the second box body 320.

[0076] In one embodiment, the thickness of the plate skeleton 110 ranges from 0.1 mm to 0.3 mm, the thickness of the first covering layer 121 ranges from 0.4 mm to 2.5 mm, and the thickness of the second covering layer 122 ranges from 0.4 mm to 2.5 mm.

[0077] The first cladding layer 121 and the second cladding layer 122 can fully cover the outer surface of the plate frame 110, which can not only protect the plate frame 110, and improve the feel and texture of the fender 100, but also avoid the problem of the sharp edge of the plate frame 110 cutting the hand. Of course, in other implementations, only the first cladding layer 121 or the second cladding layer 122 can be set. In one embodiment, the thickness of the plate frame 110 is 0.2 mm, and the thickness of the first cladding layer 121 and the second cladding layer 122 are both 1.2 mm. It can be understood that since the laser module 200 is arranged on the outside of the end face of the first end 101, the position of the laser in the vertical direction is adjustable, as long as it is ensured that the laser light can be injected into the cladding layer 120, the thickness of the first cladding layer 121 and the second cladding layer 122 does not need to consider the diameter of the light-emitting end face of the laser. Therefore, in this embodiment, the thickness of the first coating layer 121 and the second coating layer 122 can be 0.4 mm to 2.5 mm, which not only reduces the production cost but also makes the fender 100 thinner and lighter.

[0078] In one embodiment, the fender 100 has a first end 101 and a second end 102 that are opposite to each other in the length direction. The light emitted by the laser module 200 is emitted from the first end 101 to the second end 102. The fender device 10 also includes a light blocking structure (not shown in the figure), which is arranged on the end surface of the second end 102 to block the light from being emitted from the end surface of the second end 102.

[0079] The first end 101 of the fender 100 is mounted on the frame through the mounting bracket 400, and the light emitted by the laser module 200 is emitted from the first end 101 to the second end 102, that is, the light emitted by the laser module 200 is emitted from the front end to the rear end of the frame. The light emitted from the second end 102 may cause light stimulation to other riders or pedestrians behind the bicycle, thereby creating a safety hazard. In this embodiment, a light blocking structure is provided on the end surface of the second end 102 of the fender 100 to block the light from being directly emitted from the end surface of the second end 102, ensuring that the light is only reflected and scattered in the coating layer 120 of the fender 100, thereby avoiding the light emission from affecting others, thereby reducing the risk of traffic accidents.

[0080] In one embodiment, see Figure 6 and Figure 7 The laser module 200 includes a plurality of lasers, and the plurality of lasers are distributed at intervals along the width direction of the fender 100 .

[0081] The light emitted by each laser is reflected and scattered multiple times inside the cladding layer 120, and finally evenly emitted from the surface of the cladding layer 120 to form a light-emitting area. A plurality of lasers are arranged in the control box 300, and the plurality of lasers are arranged at intervals along the width direction of the cladding layer 120, so that the light emitted by the entire laser module 200 is more evenly distributed on the surface of the cladding layer 120, thereby improving the overall brightness and visibility of the light-emitting area.

[0082] In one embodiment, the light blocking structure includes at least one of reflective paper, reflective film, paint layer and coating layer, and the reflective surfaces of the reflective paper and the reflective film are arranged toward the first end 101 .

[0083] Reflective paper is a paper with reflective material coated on the surface, which can reflect light; reflective film is a plastic or metal film with high reflectivity on the surface, which can reflect light; paint layer is a coating material that can be applied on the surface of an object, has certain reflective or light-absorbing properties, and is used to change the reflection or absorption of light on the surface of the object; coating is a layer of metal or other material coated on the surface of an object by physical or chemical methods to change its optical properties, such as reflectivity, light transmittance, etc. Therefore, when light is irradiated on the light-blocking structure, due to its reflective properties, the light is reflected back into the coating layer 120, thereby reducing the loss of light energy and improving the luminous effect of the luminous area.

[0084] In one embodiment, the coating layer 120 contains fluorescent particles.

[0085] The fluorescent particles can absorb laser light of a specific wavelength emitted by the laser. After absorbing the laser energy, the fluorescent particles convert the energy into visible light of different wavelengths. The fluorescent particles scatter the laser light in the coating layer 120, so that the light is scattered in multiple directions, which helps to evenly distribute the light throughout the coating layer 120, thereby forming a uniform luminous effect. In addition, the fluorescent particles can enhance the intensity of visible light and improve the overall brightness; different fluorescent particles and laser wavelengths can be selected to change the color of the light, thereby customizing different luminous effects according to specific needs, creating a more attractive visual effect, enhancing its appearance appeal, and thus improving the market competitiveness of the product.

[0086] In one embodiment, see Figure 1 and Fig. 9 The fender 100 can be rolled along a first direction and has an unfolded state and a retracted state. The fender 100 in the unfolded state is in a long strip shape, and the fender 100 in the retracted state is in a cylindrical shape.

[0087] in, Figure 1 The fender 100 is shown in an unfolded state. Fig. 9The mudguard 100 is shown in a rolled-up state. Optionally, the mudguard 100 can be rolled along a first direction and has an unfolded state and a rolled-up state. The mudguard 100 in the unfolded state is in a long strip shape, and the mudguard 100 in the rolled-up state is in a cylindrical shape. In this way, the mudguard 100 has two usage forms (i.e., the unfolded state and the rolled-up state) for the user to choose, which can facilitate the user to change the usage form of the mudguard 100 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 100 can be unfolded along the first direction to the unfolded state to give full play to the good mud-blocking effect of the mudguard 100 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 100 can be rolled along the first direction to the rolled-up state, which can not only reduce the wind resistance and the abnormal noise caused by the shaking of the mudguard 100, but also make the bicycle sporty.

[0088] In one embodiment, see Figure 1 and Fig. 9 The plate frame 110 is configured as an elastic plate-like structure. When the fender 100 is in the unfolded state, the cross-section of the plate frame 110 perpendicular to the first direction extends along an arc, and the upper surface of the plate frame 110 forms a convex arc surface, and the lower surface of the frame forms a concave arc surface; when the fender 100 is in the retracted state, the cross-section of the plate frame 110 perpendicular to the first direction extends along a straight line.

[0089] The plate frame 110 is configured as an elastic plate-like structure. When the plate frame 110 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 110 to an unfolded state, the plate frame 110 has elastic potential energy along a direction perpendicular to the first direction (i.e., along the plane where the cross section of the plate frame 110 is located). Since the cross section of the plate frame 110 extends along an arc at this time, this structural characteristic can be used to overcome the tendency of the plate frame 110 to curl along the first direction, so that the plate frame 110 is maintained in an unfolded state.

[0090] When the user applies force to the mudguard 100 in the unfolded state, such as tapping the upper side of the mudguard 100 with a finger, so that the cross section of the plate frame 110 at a certain position becomes roughly rectangular (i.e., the cross section shape extends along a straight line), the plate frame 110 will curl along the first direction. In this way, the operation required for the mudguard 100 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 100, and the operation required for the mudguard 100 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 100 along the first direction to unfold it, and the mudguard 100 itself can remain unchanged in the unfolded state. It can be seen that the mudguard 100 of the utility model is easy to operate and full of fun, and the use state of the mudguard 100 can be changed and maintained without the help of additional fixing structures and tools.

[0091] Optionally, the plate frame 110 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 43mm to 50mm, which can effectively prevent the mudguard 100 from accidentally curling due to the shaking of the bicycle in the unfolded state, and ensure that the mudguard 100 body can be smoothly curled from the unfolded state when not in use.

[0092] In one embodiment, the inner wall surface of the installation cavity is convexly provided with reinforcing ribs, which extend toward the fender 100 and abut against the upper surface and the lower surface of the fender 100. When the fender 100 is in the retracted state, the fender 100 exerts a force directed outward on the control box 300, so that the portion where the control box 300 abuts against the fender 100 tends to be deformed, and there is a tendency for the first box body 310 and the second box body 320 to separate from each other. Therefore, reinforcing ribs are provided inside the control box 300 to stabilize the box body shape of the control box 300, suppress the deformation tendency of the fender 100, weaken the force exerted by the fender 100 on the control box 300, maintain a good matching structure between the first box body 310 and the second box body 320, and enhance the sealing effect of the control box 300.

[0093] Optionally, see Figure 2 and Figure 6 The fender device 10 further includes a main control panel and function buttons. The laser module 200 and the function buttons are electrically connected to the main control panel. The main control panel is arranged in the mounting cavity, and the function buttons are arranged on the side of the control box 300 away from the inner side. That is, they are arranged on the side of the first box body 310 away from the wheel. The function buttons are electrically connected to the main control panel to control the opening and closing, brightness and luminous color of the laser module 200. In other embodiments, a light sensing device electrically connected to the main control panel may also be provided, that is, the light sensing device senses the night or dim environment and transmits a signal to the main control panel, so that the laser module 200 emits a light warning.

[0094] Optionally, the fender device 10 further includes a power supply module disposed in the mounting cavity, the power supply module is electrically connected to the main control board, and the power supply module has a charging interface, and the control box 300 is provided with a clearance hole corresponding to the charging interface on the side away from the outer side. In this way, when the bicycle is parked outdoors or ridden outdoors, the charging interface can avoid rain and prevent water from entering the control box 300. Further optionally, the charging interface is adjacent to the front end face of the control box 300, and extends obliquely in the direction away from the outer side in the length direction of the fender 100. The front end face of the control box 300 is the end face of the control box 300 close to the mounting bracket 400, and the rear end face of the control box 300 is the end face of the control box 300 away from the mounting bracket 400. At this time, the direction of the clearance hole is opposite to the splashing direction of the muddy water splashed by the wheel, which can effectively prevent the muddy water from entering the charging interface through the clearance hole. In other embodiments, the clearance hole can also be provided on the side of the control box 300 close to the mounting bracket 400.

[0095] In one embodiment, the width of the coating layer 120 ranges from 60 mm to 100 mm, and the width of the plate frame 110 ranges from 45 mm to 55 mm.

[0096] The width of the covering layer 120 is greater than the width of the plate frame 110, so that the wide covering layer 120 extends out of the plate frame 110 in the lateral direction for a larger area, and the periphery of the covering layer 120 is equivalent to a wide brim, which can better shield mud and water, and can also control the weight and cost of the plate frame 110. In one embodiment, the width of the covering layer 120 is 70 mm, the width of the plate frame 110 is 50 mm, and the interval between the periphery of the covering layer 120 and the periphery of the plate frame 110 is 10 mm.

[0097] The utility model also provides a bicycle, which includes a frame, a wheel rotatably connected to the frame, and a mudguard device 10. The specific structure of the mudguard device 10 refers to the above embodiment. Since the bicycle adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the mudguard device 10 is arranged on the frame and is located above or to the side of the wheel.
