Description

Technical Field

[0001] This utility model relates to the field of vehicle mudguards, and in particular to an improved rain-sensing mudguard extension mechanism and an extendable mudguard. Background Technology

[0002] Mudguards are an important part of a car body, and their main function is to prevent mud, water and other debris from splashing onto the car body in rainy weather or special road conditions.

[0003] Currently, mudguards in existing technologies include fixed and extendable types. Extendable mudguards can extend in rainy weather or special road conditions to increase the protective area, while in normal weather and road conditions, at least part of the area is hidden to ensure the vehicle's aesthetics. However, the extendable mudguards reported in existing technologies mainly extend along a certain part or point on the outer circumference of the wheel. For example, CN214648589U discloses a retractable car mudguard, which designs a housing containing a motor and an arched baffle that cooperates with the wheel. One end of the arched baffle has a through hole that cooperates with the mudguard. The upper wall of the arched baffle has a sliding rail groove, and the mudguard has a sliding block that cooperates with the sliding rail groove. The sliding block has a rack, and the housing has a gear connected to the rack. The gear is connected to the motor, and the motor drives the mudguard to extend and retract through the gear to adjust the height of the mudguard.

[0004] Mudguards only extend along a certain part or point on the outer circumference of the wheel, and the extent to which they can be concealed or covered is limited. This restricts the application range of extendable mudguards on various types of vehicles and cannot achieve a good application effect. Utility Model Content

[0005] To address the problems existing in the background art, this utility model provides an improved rainwater sensing mudguard extension mechanism and an extendable mudguard.

[0006] An improved mudguard extension mechanism, comprising: An extension drive is used to drive the main body of the mudguard to move in a direction parallel to the wheel axis, thereby changing the coverage area of ​​the main body of the mudguard on the wheel. The linkage component is used to drive the mudguard sub-plate body to move along the arc contour of the mudguard main body, thereby changing the extension length of the end of the mudguard main body. The main body of the mudguard is a sandwich panel structure or a non-sandwich panel structure, and its overall shape is arc-shaped. When the main body of the mudguard is a non-sandwich panel structure, the secondary body of the mudguard moves along the arc-shaped upper surface of the main body of the mudguard. When the main body of the mudguard is a sandwich panel structure, the secondary body of the mudguard moves along at least one of the arc-shaped upper surface and the arc-shaped inner surface of the main body of the mudguard.

[0007] As described above, in an improved mudguard extension mechanism, the extension drive is connected to the main body of the mudguard via a first connector, and the extension drive is installed to a vehicle mounting point via a second connector, the vehicle mounting point being located at the chassis position of the vehicle.

[0008] In the improved mudguard extension mechanism described above, when the main mudguard body is a non-sandwich plate structure, a guide snap-fit ​​component is provided below the secondary mudguard body, and the main mudguard body is provided with a guide snap-fit ​​groove that cooperates with the guide snap-fit ​​component.

[0009] As described above, in an improved mudguard extension mechanism, the linkage may be with or without an independent power linkage.

[0010] As described above, in an improved mudguard extension mechanism, the linkage is an independently powered linkage, which is a combination of a winding drive and a winding rope, and the winding rope is connected to one end of the mudguard sub-plate.

[0011] As described above, in an improved mudguard extension mechanism, the linkage is an independently powered linkage, which is a mating assembly of a meshing drive and an arc-shaped rack, with the arc-shaped rack connected to one end of the mudguard sub-plate.

[0012] As described above, in an improved mudguard extension mechanism, the linkage is a non-independent power linkage, which is a pull rope. The pull rope is connected to one end of the mudguard sub-plate body. The pull rope passes through a rope-passing point on the vehicle body, which is located on the fender or side panel of the vehicle body. The synchronous movement of the mudguard sub-plate body is achieved by pulling the pull rope during the movement of the main mudguard body.

[0013] As described above, in an improved mudguard extension mechanism, the main mudguard body is a sandwich plate structure, the secondary mudguard body moves along the arc-shaped inner surface of the main mudguard body, and the linkage is a linkage with independent power.

[0014] As described above, in an improved mudguard extension mechanism, the main mudguard body is a non-sandwich plate structure, the secondary mudguard body moves along the arc-shaped upper surface of the main mudguard body, and the linkage is a linkage without independent power.

[0015] This utility model also provides an extendable mudguard, comprising a main mudguard body and a secondary mudguard body capable of moving along the arcuate contour of the main mudguard body, employing the improved mudguard extension mechanism described above.

[0016] Beneficial effects In the prior art, mudguards that can extend along the wheel axis are rarely reported. Mudguards that can extend both along the wheel axis and, like the technology disclosed in CN214648589U, along a certain part or point on the outer periphery of the wheel are even rarer. The improved mudguard extension mechanism and extendable mudguard provided by this utility model can extend both along the wheel axis and along the arc contour of the outer periphery of the wheel, increasing the concealment or obstruction range of the mudguard and expanding the application range of extendable mudguards. It is suitable for various vehicles, especially indoor vehicles such as sightseeing vehicles and golf carts or similar special vehicles, and has a very good application effect.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1 See Figure 1 , Figure 2 , or see Figure 5 , Figure 6 This utility model provides an improved mudguard extension mechanism, which includes: The extension drive 3 is used to drive the mudguard main body 1 to move along a direction parallel to the axis of the wheel 7, thereby changing the coverage area of ​​the mudguard main body 1 on the wheel 7.

[0022] The linkage component is used to drive the mudguard sub-plate 2 to move along the arc-shaped contour of the mudguard main plate 1, thereby changing the extension length of the end of the mudguard main plate 1.

[0023] The mudguard main body 1 mentioned above is a sandwich plate structure. Figure 1 , Figure 2 ) or non-mezzanine structure ( Figure 5 , Figure 6 The overall shape is curved to fit the wheel profile and can be made of hard plastic or thin aluminum alloy sheet.

[0024] When the main body 1 of the mudguard is a non-sandwich plate structure, the secondary body 2 of the mudguard moves along the arc-shaped upper surface of the main body 1 of the mudguard. Figure 5 , Figure 6 The mudguard sub-plate 2 in the middle is shown in solid line.

[0025] When the main body 1 of the mudguard is a sandwich panel structure, the secondary body 2 of the mudguard moves along at least one of the arc-shaped upper surface and the arc-shaped inner surface of the main body 1 of the mudguard, for example, it moves only along the arc-shaped inner surface of the main body 1 of the mudguard. Figure 1 , Figure 2 The mudguard sub-plate 2 in the middle is shown with a dashed line.

[0026] Referring to the accompanying drawings, the elongation drive 3 is connected to the mudguard main body 1 via the first connector 5, and the elongation drive 3 is installed to the vehicle body mounting point 4 via the second connector 6. The vehicle body mounting point 4 is located at the vehicle chassis position, and the side position of the brake base plate can be preferred.

[0027] The extension drive 3 is preferably an electric push rod, and the model can be LSTN-A.

[0028] In the prior art, mudguards that can extend along the wheel axis are rarely reported. Mudguards that can extend both along the wheel axis and, like the technology disclosed in CN214648589U, along a certain part or point on the outer periphery of the wheel are even rarer. The improved mudguard extension mechanism and extendable mudguard provided by the above embodiments of this utility model can extend both along the wheel axis and along the arc contour of the outer periphery of the wheel, increasing the concealment or coverage of the mudguard and expanding the application range of extendable mudguards. They are suitable for various vehicles, especially indoor vehicles such as golf carts and sightseeing vehicles or similar special vehicles, and have excellent application effects.

[0029] Next, based on Embodiment 1, we will introduce various implementations of the present invention with more detailed different embodiments.

[0030] Example 2 Based on Example 1, see Figure 1 , Figure 2 and Figure 3 This embodiment provides an improved mudguard extension mechanism, which includes an extension drive 3, which is an electric push rod used to drive the mudguard main body 1 to move along a direction parallel to the axis of the wheel 7, thereby changing the coverage area of ​​the mudguard main body 1 on the wheel 7.

[0031] See also Figure 1 , Figure 2 The elongation drive 3 is connected to the mudguard main body 1 via the first connector 5, and the elongation drive 3 is installed to the vehicle body mounting point 4 via the second connector 6. In this embodiment, the vehicle body mounting point 4 is located on the side of the brake base plate on the vehicle chassis.

[0032] In this embodiment, both the first connector 5 and the second connector 6 adopt the simplest structure of connecting block combined with bolt or screw fasteners, and welding can be used locally as an aid.

[0033] In this embodiment, the main body 1 of the mudguard is a sandwich panel structure with an overall arc shape to adapt to the wheel profile, and is made of hard plastic or aluminum alloy sheet.

[0034] In this embodiment, the mudguard sub-plate 2 is moved along the arc-shaped contour of the mudguard main plate 1 by means of the linkage component. Specifically, it moves along the arc-shaped inner surface of the mudguard main plate 1, changing the extension length of the end of the mudguard main plate 1.

[0035] In this embodiment, the linkage is a linkage with independent power, specifically selected as follows: Figure 3 The shown assembly of the winding drive 8 and winding rope 9 is located inside the sandwich panel structure of the main mudguard body 1. The winding rope 9 is connected to one end of the secondary mudguard body 2. The winding drive 8 is a winch motor. Driven by the winding drive 8 and winding rope 9, the secondary mudguard body 2 moves along the arc-shaped inner surface of the main mudguard body 1, unfolding or retracting. The lowest end of the sandwich panel structure of the main mudguard body 1 has an opening that allows the secondary mudguard body 2 to pass through. In this case, the secondary mudguard body 2 has a certain self-weight, allowing it to move smoothly downwards when the winding drive 8 drives the winding rope 9 to unfold. It can be made of metal sheet or plastic sheet with counterweight.

[0036] The extendable mudguard provided in this embodiment includes the aforementioned mudguard main body 1 and mudguard secondary body 2. Both adopt the improved mudguard extension mechanism described above. They work together through the extension drive 3 and the linkage mechanism described above, which is composed of the winding drive 8 and the winding rope 9. In rainy weather or special road conditions, the mudguard main body 1 is driven to move towards the wheel 7 in a direction parallel to the axis of the wheel 7, increasing the coverage area of ​​the mudguard main body 1 on the wheel 7. At the same time, the mudguard secondary body 2 is driven to move downward along the arc contour of the mudguard main body 1, increasing the extension length of the end of the mudguard main body 1, thereby increasing the protective area and effectively reducing mud and water splashed onto the vehicle body.

[0037] In normal weather and road conditions, when mud and water protection is not required, the main mudguard body 1 is driven to move away from the wheel 7 along a direction parallel to the axis of the wheel 7. At the same time, the secondary mudguard body 2 is driven to move upward along the arc contour of the main mudguard body 1, reducing the extension length of the end of the main mudguard body 1 and potentially hiding the area of ​​the exposed mudguard part, thus ensuring the vehicle's aesthetics.

[0038] Example 3 Based on Example 1, see Figure 1 , Figure 2 and Figure 4This embodiment provides an improved mudguard extension mechanism, which includes an extension drive 3, which is an electric push rod used to drive the mudguard main body 1 to move along a direction parallel to the axis of the wheel 7, thereby changing the coverage area of ​​the mudguard main body 1 on the wheel 7.

[0039] See also Figure 1 , Figure 2 The elongation drive 3 is connected to the mudguard main body 1 via the first connector 5, and the elongation drive 3 is installed to the vehicle body mounting point 4 via the second connector 6. In this embodiment, the vehicle body mounting point 4 is located on the side of the brake base plate on the vehicle chassis.

[0040] In this embodiment, both the first connector 5 and the second connector 6 adopt the simplest structure of connecting block combined with bolt or screw fasteners, and welding can be used locally as an aid.

[0041] In this embodiment, the main body 1 of the mudguard is a sandwich panel structure with an overall arc shape to adapt to the wheel profile, and is made of hard plastic or aluminum alloy sheet.

[0042] In this embodiment, the mudguard sub-plate 2 is moved along the arc-shaped contour of the mudguard main plate 1 by means of the linkage component. Specifically, it moves along the arc-shaped inner surface of the mudguard main plate 1, changing the extension length of the end of the mudguard main plate 1.

[0043] In this embodiment, the linkage is a linkage with independent power, specifically selected as follows: Figure 4 The meshing drive component 10 and the arc-shaped rack 11 shown are both housed within the sandwich panel structure of the main mudguard body 1. The meshing drive component 10 is a geared motor with gears. The arc-shaped rack 11 is mounted inside the main mudguard body 1 via a guide limiting component 12 that slides with it. This allows the arc-shaped rack 11 to mesh with the gears of the meshing drive component 10 and be driven to move by the gears. The end of the arc-shaped rack 11 is connected to the mudguard sub-plate 2, thus enabling the mudguard sub-plate 2 to move along the arc-shaped inner surface of the main mudguard body 1 under the drive of the meshing drive component 10 and the arc-shaped rack 11, unfolding or retracting. The lowest end of the sandwich panel structure of the main mudguard body 1 has an opening that allows the mudguard sub-plate 2 to pass through. In this case, there is no need to emphasize the weight of the mudguard sub-plate 2; ordinary plastic or metal sheets can be used.

[0044] The extendable mudguard provided in this embodiment includes the aforementioned mudguard main body 1 and mudguard secondary body 2. Both adopt the improved mudguard extension mechanism described above. They work together through the extension drive 3 and the linkage described above, which is engaged by the meshing drive 10 and the arc-shaped rack 11. In rainy weather or special road conditions, the mudguard main body 1 is driven to move towards the wheel 7 in a direction parallel to the axis of the wheel 7, increasing the coverage area of ​​the mudguard main body 1 on the wheel 7. At the same time, the mudguard secondary body 2 is driven to move downward along the arc-shaped contour of the mudguard main body 1, increasing the extension length of the end of the mudguard main body 1, thereby increasing the protective area and effectively reducing mud and water splashed onto the vehicle body.

[0045] In normal weather and road conditions, when mud and water protection is not required, the main mudguard body 1 is driven to move away from the wheel 7 along a direction parallel to the axis of the wheel 7. At the same time, the secondary mudguard body 2 is driven to move upward along the arc contour of the main mudguard body 1, reducing the extension length of the end of the main mudguard body 1 and potentially hiding the area of ​​the exposed mudguard part, thus ensuring the vehicle's aesthetics.

[0046] Example 4 Based on Example 1, see Figure 5 , Figure 6 as well as Figures 7 to 9 This embodiment provides an improved mudguard extension mechanism, which includes an extension drive 3, which is an electric push rod used to drive the mudguard main body 1 to move along a direction parallel to the axis of the wheel 7, thereby changing the coverage area of ​​the mudguard main body 1 on the wheel 7.

[0047] See also Figure 5 , Figure 6 The elongation drive 3 is connected to the mudguard main body 1 via the first connector 5, and the elongation drive 3 is installed to the vehicle body mounting point 4 via the second connector 6. In this embodiment, the vehicle body mounting point 4 is located on the side of the brake base plate on the vehicle chassis.

[0048] In this embodiment, both the first connector 5 and the second connector 6 adopt the simplest structure of connecting block combined with bolt or screw fasteners, and welding can be used locally as an aid.

[0049] In this embodiment, the main body 1 of the mudguard is a non-sandwich plate structure, with an overall arc shape to adapt to the wheel profile, and is made of hard plastic or aluminum alloy sheet.

[0050] In this embodiment, the mudguard sub-plate 2 is moved along the arc-shaped contour of the mudguard main plate 1 by means of the linkage component. Specifically, it moves along the arc-shaped upper surface of the mudguard main plate 1, changing the extension length of the end of the mudguard main plate 1.

[0051] In this embodiment, the linkage is a linkage without independent power; the specific selection is as follows: Figure 7 , Figure 8 The pull rope 13 shown has one end connected to a part that can be pulled by the main body 1 of the mudguard, such as the front end of the extension drive 3 (the position of the first connector 5). The pull rope 13 passes through the rope crossing point 14 of the vehicle body, and the other end is connected to the front end of the mudguard sub-plate 2. The mudguard sub-plate 2 moves synchronously by pulling the pull rope 13 during the movement of the main body 1 of the mudguard.

[0052] In this embodiment, since the fender sub-plate 2 moves synchronously by pulling the pull rope 13 during the movement of the main fender 1, a rope passage point 14 needs to be set at the position of the fender or side panel. This point is provided with a rope passage hole 15 so that the pull rope 13 can pass through smoothly. The rope passage hole 15 can be a separate perforated component or a hole directly opened on the fender or side panel.

[0053] Whether the rope crossing point 14 on the vehicle body is located on the fender or the side panel will vary depending on the vehicle model and sheet metal process, but as long as the pulling distance is appropriate, it is fine.

[0054] Additionally, as needed, one or more guide rope portions 16 can be provided at the locations through which the pull rope 13 passes (such as the upper surface of the mudguard main body 1) to constrain the passing position and distance of the pull rope 13.

[0055] Because the main body 1 of the mudguard can pull the towing rope 13 during its movement, it drives the secondary body 2 of the mudguard to move along the arc-shaped upper surface of the main body 1, thus unfolding or retracting. In this case, the secondary body 2 of the mudguard has a certain weight, which allows it to move smoothly downwards when the towing rope 13 releases it. It can be made of metal sheet or plastic sheet with counterweight.

[0056] Furthermore, since the main body 1 of the mudguard in this embodiment is a non-sandwich plate structure, such as Figure 9 As shown, a guide clip 17 is also provided below the mudguard sub-plate 2, combined with... Figure 7 , Figure 8 A guide slot 18 is provided on the main body 1 of the mudguard to cooperate with the guide slot 17, so as to prevent the mudguard sub-plate 2 from deviating. The guide slot 18 can be a cut on the main body 1 of the mudguard that corresponds to the sliding path of the guide slot 17.

[0057] The extendable mudguard provided in this embodiment includes the aforementioned mudguard main body 1 and mudguard secondary body 2. Both adopt the improved mudguard extension mechanism described above. They work together as linkages via the extension drive 3 and the pull rope 13 described above. In rainy weather or special road conditions, the mudguard main body 1 is driven to move towards the wheel 7 in a direction parallel to the axis of the wheel 7, increasing the coverage area of ​​the mudguard main body 1 on the wheel 7. At the same time, the mudguard secondary body 2 is driven to move downward along the arc contour of the mudguard main body 1, increasing the extension length of the end of the mudguard main body 1, thereby increasing the protective area and effectively reducing mud and water splashed onto the vehicle body.

[0058] In normal weather and road conditions, when mud and water protection is not required, the main mudguard body 1 is driven to move away from the wheel 7 along a direction parallel to the axis of the wheel 7. At the same time, the secondary mudguard body 2 is driven to move upward along the arc contour of the main mudguard body 1, reducing the extension length of the end of the main mudguard body 1 and potentially hiding the area of ​​the exposed mudguard part, thus ensuring the vehicle's aesthetics.

[0059] Example 5 This embodiment is a modification of embodiment 2. In this embodiment, the mudguard main body 1 of embodiment 2 is changed to a non-sandwich plate structure.

[0060] In this case, besides the original Figure 3 The winding drive unit 8, winding rope 9, and mudguard sub-plate 2 shown are disposed on the outer arc-shaped upper surface of the mudguard main plate 1, and are introduced into the mudguard sub-plate 2 and the mudguard main plate 1. Figure 9 The guide connector 17 shown and Figure 7 , Figure 8 The guide slot 18 shown is identical to the rest. The specific structural principle has been described in detail in the previous embodiments and will not be repeated here.

[0061] Example 6 This embodiment is a modification of embodiment 3. In this embodiment, the mudguard main body 1 of embodiment 3 is changed to a non-sandwich plate structure.

[0062] In this case, besides the original Figure 4 The meshing drive component 10, the arc-shaped rack 11, the guide limit component 12, and the mudguard sub-plate body 2 shown are disposed outside the arc-shaped upper surface of the mudguard main body 1, and are introduced into the mudguard sub-plate body 2 and the mudguard main body 1. Figure 9 The guide connector 17 shown and Figure 7 , Figure 8 The guide slot 18 shown is identical to the rest. The specific structural principle has been described in detail in the previous embodiments and will not be repeated here.

[0063] Example 7 This embodiment is a modification of embodiment 4. In this embodiment, the mudguard main body 1 of embodiment 4 is replaced with a sandwich plate structure.

[0064] In this case, besides the original Figure 7 , Figure 8 , Figure 9 The mudguard sub-plate 2 shown is disposed on the arc-shaped inner surface of the mudguard main plate 1. One end of the pull rope 13 also passes through the sandwich shell of the mudguard main plate 1 before connecting to the outside of the mudguard sub-plate 2. The rest can remain unchanged. The guide snap-fit ​​17 and guide snap-fit ​​groove 18 provided on the mudguard sub-plate 2 and the mudguard main plate 1 can be retained or omitted. The specific structural principle has been described in detail in the previous embodiments and will not be repeated here.

[0065] Example 8 This embodiment is an improvement on embodiment 2. Although the main mudguard body 1 of embodiment 2 has a sandwich plate structure, this embodiment also introduces a sub-plate body 2 and a lower plate of the main mudguard body 1. Figure 9 The guide connector 17 shown and Figure 7 , Figure 8 The guide slot 18 shown is used to improve guiding performance; the rest can remain unchanged. The specific structural principle has been described in detail in the previous embodiments and will not be repeated here.

[0066] It should be noted that although this utility model provides some application examples of the improved mudguard extension mechanism and extendable mudguard that are of interest and protected, these application examples should not be construed as limiting this utility model.

[0067] For example, there are no restrictions on the type of vehicle, whether it is a special-purpose vehicle or not.

[0068] For example, regarding the extension of the mudguards, should it be controlled automatically with rain sensors, as is done in some existing technologies, or should it be triggered manually without any restrictions?

[0069] Therefore, the following embodiments 9 to 13 are all examples illustrating some applications of this utility model, only to more clearly illustrate the scope of application of this application, and should not be construed as limiting this application.

[0070] Example 9 This embodiment is an example of the vehicle type to which the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8 are applied. In this embodiment, the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8 are applied to a sightseeing vehicle.

[0071] A sightseeing vehicle is a special vehicle for indoor use. Its chassis and body have a large design space. The space between the fenders and wheels of this type of vehicle is more exposed, which meets the dual requirements of preventing mud and water and pursuing aesthetics.

[0072] Example 10 This embodiment is an example of the vehicle type to which the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8 are applied. In this embodiment, the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8 are applied to ordinary passenger cars to replace the existing mudguards.

[0073] Example 11 This embodiment is an example of the application of the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8. In this embodiment, the extension drive 3 or the extension drive 3 and the rewind drive 8, or the extension drive 3 and the engagement drive 10 of the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8 are directly connected to the vehicle's power supply (not limited to the built-in power supply, backup power supply or other independent power supply). It can be easily triggered manually by a button or touch button. In rainy weather or special road conditions, the main mudguard body 1 is driven to move towards the wheel 7 in a direction parallel to the axis of the wheel 7, increasing the coverage area of ​​the main mudguard body 1 on the wheel 7. At the same time, the secondary mudguard body 2 is driven to move downward along the arc contour of the main mudguard body 1, increasing the extension length of the end of the main mudguard body 1, thereby increasing the protective area and effectively reducing mud and water splashed onto the vehicle body. Under normal weather and road conditions, when mud and water protection is not required, the main mudguard body 1 is driven to move away from the wheel 7 along a direction parallel to the axis of the wheel 7. At the same time, the secondary mudguard body 2 is driven to move upward along the arc contour of the main mudguard body 1, reducing the extension length of the end of the main mudguard body 1 and potentially hiding the area of ​​the exposed mudguard part to ensure the vehicle's aesthetics.

[0074] Example 12 This embodiment is an example of the application of the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8. In this embodiment, the extension drive 3 or the extension drive 3 and the rewind drive 8, or the extension drive 3 and the engagement drive 10 of the improved mudguard extension mechanism and extendable mudguard provided in Embodiments 1-8 are connected to a controller. The controller is also connected to a rain sensor. The controller automatically controls the operation of the electrical components according to the signal from the rain sensor. In rainy weather or special road conditions, the main mudguard body 1 is driven to move towards the wheel 7 in a direction parallel to the axis of the wheel 7, increasing the coverage area of ​​the main mudguard body 1 on the wheel 7. At the same time, the auxiliary mudguard body 2 is driven to move downward along the arc contour of the main mudguard body 1, increasing the extension length of the end of the main mudguard body 1, thereby increasing the protection area and effectively reducing mud and water splashed onto the vehicle body. Under normal weather and road conditions, when mud and water protection is not required, the main mudguard body 1 is driven to move away from the wheel 7 along a direction parallel to the axis of the wheel 7. At the same time, the secondary mudguard body 2 is driven to move upward along the arc contour of the main mudguard body 1, reducing the extension length of the end of the main mudguard body 1 and potentially hiding the area of ​​the exposed mudguard part to ensure the vehicle's aesthetics.

[0075] Example 13 This embodiment is based on Embodiment 12, providing an example of the selection and installation of the automatic control components in Embodiment 12. In this embodiment, the rain sensor includes a probe and a main board. The probe detects rainwater signals, and the main board transmits these signals to the controller. The probe is positioned in a location on the vehicle chassis where water is easily accumulated, such as between the mudguard and the tire near the front of the vehicle. The main board is located inside the vehicle compartment. With this embodiment, because the probe is positioned between the mudguard and the tire near the front of the vehicle, mud and water splashed up by the tires during driving will immediately adhere to the probe, allowing for rapid detection of rain and control of the extendable mudguard in this application to respond. In this embodiment, the controller can select a 12V DC relay and use a DC converter to provide 12V power. The 12V DC relay 3 can be a JQX-30F / 2Z 30A 8-pin high-power relay, which is simple to use and facilitates routine wiring operations by those skilled in the art.
