Description

Technical Field

[0001] This utility model relates to the field of mudguard technology, specifically a vehicle mudguard angle adjustment mechanism that adapts to road conditions. Background Technology

[0002] Vehicle mudguards are crucial components protecting the vehicle body and surrounding environment from splashed mud, water, and gravel, playing a vital role in automotive protection systems. Currently, most vehicle mudguards employ a fixed angle and length integrated structure, directly fixed to the vehicle's wheel arches via simple connectors. Their structure and posture cannot be dynamically adjusted according to road conditions. This fixed structure has several limitations in practical use: at high-speed cruising, the fixed main body has a large windward area and a high drag coefficient, increasing fuel consumption and making the connection between the main body and the vehicle body susceptible to fatigue damage from high-frequency airflow impacts; when driving on muddy, rainy, or gravel roads, the fixed length of the main body provides limited protection, allowing mud and water to easily splash onto the vehicle body, while gravel can easily impact the main body, causing scratches or dents; facing complex road conditions such as slopes and bumps, the fixed angle of the main body cannot adapt to the vehicle's posture, potentially causing scraping against the ground or structural interference, significantly reducing the protective effect and accelerating wear and tear on the main body.

[0003] Public technical solution CN223086122U discloses an improved vehicle mudguard, comprising a front body and a rear bonding plate. This solution eliminates any connection holes on the front of the mudguard body, facilitating washing and preventing mud from entering the vehicle body, thus ensuring interior cleanliness. Even if wastewater enters the rear from the connection between the top of the mudguard and the body, it is blocked by the outer bonding plate and flows downwards to the inner bonding plate, preventing contamination of the vehicle's exterior. However, in practice, the fixed angle and length of the mudguard body result in high wind resistance at high speeds, making the connection between the body and the bonding plate susceptible to fatigue damage from high-frequency vibrations. This leads to decreased fuel economy, insufficient protection on muddy and gravel roads, mud and water splashing, and the body being easily damaged by impacts from gravel. Furthermore, the mudguard is unsuitable for sloping or bumpy roads, easily scraping against the ground or interfering with the structure, significantly reducing its effectiveness and exacerbating damage.

[0013] The beneficial effects of this utility model are: 1. This utility model achieves precise dual-dimensional adjustment of the mudguard's length and angle through the coordinated action of the length adjustment motor and length adjustment screw of the adjustment component and the angle adjustment motor and angle adjustment screw. In conjunction with the linkage of the car's built-in sensors and vehicle controller, it can adapt to various road conditions such as high-speed cruising, muddy and rainy weather, and slopes.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1: Please refer to Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a vehicle mudguard angle adjustment mechanism that adapts to road conditions, including a protective component 1 and an adjustment component 2 for adjusting the protective length and angle. Protective component 1 includes: a main body 101; an adhesive plate 105 connected to the rear end of the main body 101 via a bearing; and a vehicle body 102 disposed on the upper end of the adhesive plate 105; The adjustment assembly 2 includes: a length adjustment motor 201 fixed inside the main body 101 by external bolts; and a length adjustment lead screw 202 keyed to the power output end of the length adjustment motor 201.

[0020] Specifically, the protective component 1 also includes: an extension plate 103 and a cleaning scraper 104; the extension plate 103 is threaded to the lower part of the length adjusting screw 202, and the extension plate 103 is slidably connected to the inside of the main body 101; the cleaning scraper 104 is installed at the lower end of the main body 101.

[0021] Furthermore, when the extension plate 103 retracts inward, the cleaning scraper 104 fits tightly against the surface of the extension plate 103, which can scrape off the mud, water and impurities attached to its surface.

[0022] Specifically, the adjustment component 2 also includes: an angle adjustment motor 203 and an angle adjustment screw 204; the angle adjustment motor 203 is fixed to the inside of the bonding plate 105 by external bolts; the angle adjustment screw 204 is keyed to the power output end of the angle adjustment motor 203.

[0023] Furthermore, the angle adjustment motor 203 rotates, driving the angle adjustment lead screw 204 to rotate.

[0024] Specifically, the adjustment component 2 also includes: a first adjustment block 205 and a T-block 207; the first adjustment block 205 is threadedly connected to the surface of the angle adjustment screw 204; the T-block 207 is fixed to one end of the first adjustment block 205.

[0025] Furthermore, the first adjusting block 205 moves, which in turn pulls the second adjusting block 206 to move via the T-block 207.

[0026] In use, the length adjustment motor 201 and angle adjustment motor 203 of the adjustment component 2 are connected to the vehicle's on-board controller via wires to form a closed-loop control link from sensor to controller to actuator. During operation, the vehicle's on-board sensors transmit data to the on-board controller in real time via the CAN bus. The wheel speed sensor accurately detects the vehicle's speed, the vehicle attitude sensor captures the body tilt angle of the body 102, the rain sensor monitors the rainfall intensity, and the ABS sensor determines the tire slip rate. Comprehensive perception of road conditions and driving status can be achieved without the need for additional sensors. The vehicle controller matches preset operating condition logic based on sensor data and outputs control commands to the adjustment component 2: When the high-speed cruising condition is determined, the controller commands the length adjustment motor 201 to reverse, and its power output end drives the length adjustment screw 202 to reverse synchronously through a key connection. Because the extension plate 103 is threadedly connected to the length adjustment screw 202 and cannot rotate due to the constraint of the internal limiting structure of the main body 101, it retracts inward along the screw axis, shortening the overall length of the mudguard to reduce the frontal area; on the other hand, the controller commands the angle adjustment motor 203 to rotate forward, driving the angle adjustment screw 204 connected to the key to rotate. The first adjustment block 205, which is threadedly connected to the screw, moves along the screw axis, and the T-shaped block 207 fixed at its end slides and adapts in the groove of the second adjustment block 206; since the second adjustment block 206 is connected to the main body 101 through a rotating shaft, the first adjustment block 205 pushes the second adjustment block 206, thereby driving the main body 101 to rotate upward, realizing the mudguard tilting upward, reducing wind resistance and improving fuel economy. When the sensor detects When operating in muddy or rainy conditions, the vehicle controller commands the length adjustment motor 201 to rotate forward, causing the length adjustment screw 202 to drive the extension plate 103 to extend outward along the inside of the main body 101, expanding the mud-blocking range. Simultaneously, it commands the angle adjustment motor 203 to rotate in reverse, causing the angle adjustment screw 204 to drive the first adjustment block 205 to move in the opposite direction. This, through the T-block 207, pulls the second adjustment block 206, causing the main body 101 to deflect downwards, bringing the extension plate 103 closer to the ground and reducing mud and water splashing. If the vehicle attitude sensor detects an oblique angle... On sloping sections, the controller instructs the angle adjustment motor 203 to rotate in one direction, driving the main body 101 to tilt towards the vehicle body 102, blocking tire splashes and preventing mud and water from adhering to the vehicle body 102. The cleaning scraper 104 of the protective component 1 is fixed to the lower end of the main body 101. When the extension plate 103 retracts inward, the cleaning scraper 104 is in close contact with the surface of the extension plate 103, which can scrape off the mud, water and impurities adhering to its surface, preventing dirt accumulation from causing the extension plate 103 to slide and get stuck, and ensuring the long-term stable operation of the adjustment mechanism.

[0027] In summary, this utility model achieves precise dual-dimensional adjustment of the mudguard's length and angle through the coordinated action of the length adjustment motor 201, length adjustment screw 202, angle adjustment motor 203, and angle adjustment screw 204 in the adjustment component 2. Combined with the linkage between the vehicle's built-in sensors and the onboard controller, it can adapt to various road conditions such as high-speed cruising, muddy and rainy weather, and slopes. At high speeds, the length adjustment screw 202 drives the extension plate 103 to retract, and the angle adjustment screw 204 drives the main body 101 to tilt upwards to reduce wind resistance. In complex road conditions, the extension plate 103 extends, and the main body 101 tilts downwards to expand the protection range, significantly improving the mudguard's adaptability and practical value. This invention utilizes the structural cooperation between the cleaning scraper 104 of the protective component 1 and the extension plate 103. When the length adjustment motor 201 drives the extension plate 103 to retract inward, the cleaning scraper 104 can closely adhere to the surface of the extension plate 103 to scrape away the attached mud, water and impurities, effectively avoiding the problem of sliding and jamming of the extension plate 103 caused by the accumulation of dirt, reducing the risk of mechanism failure, and significantly improving the long-term operational stability and service life of the adjustment component 2.

[0028] Example 2: Please refer to Figures 1-6 This is the second embodiment of the present utility model.

[0031] Specifically, the T-block 207 is engaged in the slide groove, and the first adjusting block 205 is slidably connected to the second adjusting block 206 through the T-block 207.

[0032] Furthermore, the first adjusting block 205 pulls the second adjusting block 206 through the T-block 207.

[0033] Specifically, the adjustment component 2 also includes: ball bearings 208; the ball bearings 208 are fitted into the inner wall of the right end of the bonding plate 105, and a number of ball bearings 208 are evenly distributed on the inner wall of the right end of the bonding plate 105.

[0034] Furthermore, the ball bearings 208 on the inner wall of the right end of the bonding plate 105 reduce the frictional resistance when the second adjusting block 206 moves.

[0035] Specifically, a fixing component 3 is provided on the rear side of the protective component 1.

Then, the fixing plate 302 is fastened to the surface of the vehicle body 102 by bolts, so that the bonding plate 105 is tightly fitted to the vehicle body 102, and the entire mechanism is stably assembled at the wheel arch of the vehicle.

[0037] In use, the pins 301 of the fixing component 3 are vertically inserted into the preset holes of the vehicle body 102 to form a preliminary positioning. Then, the fixing plate 302 is fastened to the surface of the vehicle body 102 with bolts, so that the bonding plate 105 is tightly fitted to the vehicle body 102.
