Description

Technical Field

[0001] This utility model belongs to the technical field of trucks and accessories, and particularly relates to an electric fairing assembly and a truck. Background Technology

[0002] In the design and use of trucks, the height difference between the vehicle body and the cargo box increases wind resistance, leading to increased fuel consumption. To address this issue, automakers generally use fairings to compensate for the height difference, making the vehicle body and cargo box more compatible. However, fairings typically only fit cargo boxes of a certain height. Sometimes users change the cargo box, and if the cargo box is too low or too high, the overall wind resistance will increase, failing to achieve the optimal effect of reducing fuel consumption.

[0003] Currently, some automakers have designed manually adjustable fairings, but because these fairings are mounted on the roof, they are not easy to operate, making adjustment difficult for users. Furthermore, users are unsure of the appropriate adjustment angle, thus failing to achieve the optimal fuel efficiency. Other automakers have designed electrically adjustable fairings, solving the difficulty of adjustment but not addressing the optimal adjustment angle. Therefore, none of these solutions address the optimal fit between the vehicle body and cargo box, failing to achieve the best possible balance. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides an electric fairing assembly and truck, which solves the problem of difficulty in manual adjustment by users. It can be continuously adjusted within a certain angle to ensure the matching of the vehicle body and cargo box, and users can precisely adjust the angle of the fairing.

[0005] This utility model is implemented as follows: On the one hand, it provides an electric deflector assembly, including two side deflectors arranged at relative intervals, a top deflector mounted on the side deflectors, and an electric height adjustment mechanism for driving the top deflector to rise and fall is provided on the inner side of the top deflector. A laser sensor is provided on the end face of the top-layer air deflector facing the cargo box side; It also includes a control unit, which includes a controller. The laser sensor is communicatively connected to the input of the controller, and the output of the controller is communicatively connected to the drive motor in the electric height adjustment mechanism.

[0006] Furthermore, the two sides of the top-level air deflector extend downward to form extensions, and the extensions on both sides overlap with the upper ends of the two side air deflectors respectively.

[0007] Furthermore, the electric height adjustment structure includes a drive motor and a lead screw and nut assembly. The lead screw in the lead screw and nut assembly is connected to the drive motor, and a connecting rod is hinged to the nut in the lead screw and nut assembly. The connecting end of the connecting rod is hinged to the inner surface of the top-level air guide. The drive motor drives the nut to move linearly on the lead screw and drives the top-level air guide to rise and fall through the connecting rod assembly.

[0008] Furthermore, the drive motor is a dual-head motor, and the lead screw nut pair and the connecting rod component are each provided with two sets. The lead screws on the two sets of lead screw nut pairs are respectively connected to the dual-head motor. The drive motor drives the nuts on the two sets of lead screw nut pairs to move in opposite directions or towards each other. The two sets of connecting rod components are respectively hinged to the nuts on the two sets of lead screw nut pairs.

[0009] Furthermore, three laser sensors are provided, one on the vehicle body axis and the other on both sides of the vehicle body axis.

[0010] On the other hand, a truck is provided that includes any of the electric fairing assemblies described above.

[0011] The advantages and technical effects of this utility model are as follows: By adopting the above technical solution, the problem of manual adjustment by the user is solved. It can be continuously adjusted within a certain angle to ensure that the vehicle body and cargo box match, and the user can precisely adjust the angle of the fairing. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0015] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] like Figure 1 As shown, this application provides an electric fairing assembly, including two side fairings 1 arranged at relative intervals, a top fairing 2 mounted on the side fairings 1, an electric height adjustment mechanism 3 for driving the top fairing 2 to rise and fall on the inner side of the top fairing 2; and a laser sensor 4 is provided on the end face of the top fairing 2 facing the cargo box side. The system also includes a control unit, which comprises a controller. The laser sensor 4 is communicatively connected to the input of the controller, and the output of the controller is communicatively connected to the drive motor in the electric height adjustment mechanism 3. Through the synergistic effect of the electric height adjustment mechanism 3 and the laser sensor 4, the problem of increased vehicle drag caused by the mismatch between the height of the traditional fairing and the cargo box is effectively solved. The laser sensor 4 detects the cargo box height in real time and transmits the data to the controller. Based on this information, the controller automatically adjusts the height of the top-level fairing 2 to maintain optimal alignment with the cargo box. This system achieves precise height adjustment, overcoming the difficulties of manual adjustment and compensating for the inability of ordinary electric fairings to intelligently determine the adjustment angle. Ultimately, it significantly reduces wind resistance and fuel consumption, improving the overall vehicle economy and operational convenience.

[0017] like Figure 2 As shown, specifically, the control unit includes a controller, which uses an STM32F103; The laser module includes a laser sensor 4. The laser module and the controller are connected for communication to transmit high and low level control signals. The power drive module that controls the drive motor is an L298N. The power drive module communicates with the controller to realize the transmission of PWM control signals. The power drive module controls the drive motor to work, thereby realizing the lifting and lowering of the top-level guide shroud 2. The mobile app communicates with the controller via a Bluetooth module for remote control by the user. The Bluetooth module is HC-05 / 08.

[0018] The system uses the vehicle's 12V power supply, which is stepped down through a power circuit to provide stable DC voltages for the controller, laser module, power drive module, and Bluetooth module.

[0019] Furthermore, the top-level fairing 2 extends downwards on both sides to form extensions, which overlap with the upper ends of the two side deflectors 1. This compensates for the gap between the fairing and the vehicle roof caused by the lifting of the top-level fairing 2, thereby effectively reducing the drag coefficient.

[0020] Furthermore, the electric height adjustment structure includes a drive motor and a lead screw and nut assembly. The lead screw in the lead screw and nut assembly is connected to the drive motor, and a connecting rod is hinged to the nut in the lead screw and nut assembly. The connecting end of the connecting rod is hinged to the inner surface of the top-layer air guide shroud 2. The drive motor drives the nut to move linearly on the lead screw, and drives the top-layer air guide shroud 2 to rise and fall through the connecting rod assembly. The combination of the lead screw and nut assembly and the connecting rod mechanism provides high transmission efficiency and precise positioning, enabling smooth and reliable lifting and lowering adjustment of the top-layer air guide shroud 2.

[0021] Preferably, the drive motor is a dual-head motor, and the lead screw and nut pair and the connecting rod component are provided in two sets. The lead screws on the two sets of lead screw and nut pairs are respectively connected to the dual-head motor. The drive motor drives the nuts on the two sets of lead screw and nut pairs to move in opposite directions or towards each other. The two sets of connecting rod components are respectively hinged to the nuts on the two sets of lead screw and nut pairs. By using a dual-head motor to synchronously drive two sets of symmetrically distributed lead screw and nut pairs and connecting rod mechanisms, synchronous and balanced lifting of the top-level guide shield 2 on both sides can be achieved, effectively preventing jamming or structural deformation caused by uneven force on one side, and significantly improving the stability and reliability of the adjustment process.

[0022] Furthermore, three laser sensors 4 are provided, one on the vehicle body axis and the other on both sides of the vehicle body axis. By symmetrically arranging three laser sensors 4 along the vehicle body axis and both sides, height information of different positions of the cargo box can be collected simultaneously, realizing comprehensive perception and accurate measurement of the cargo box's planar attitude; based on multi-sensor data fusion, the system can more accurately calculate the height and angle that the fairing needs to be adjusted, significantly improving the aerodynamic matching accuracy with the cargo box.

[0023] On the other hand, a method for adjusting the fairing is provided. The control method is used for any of the electric fairing assemblies described above. The control method includes that when the user starts the electric height adjustment mechanism 3 to adjust the fairing, the laser sensor 4 is simultaneously activated to emit a red laser beam. The position of the red laser beam illuminating the cargo box is observed to determine whether the fairing adjustment is in place.

[0024] Furthermore, the laser sensor 4 emits a red laser beam that illuminates the top of the cargo box, ensuring that the tangent of the rear edge of the fairing is aligned with the top of the cargo box; this state indicates that the adjustment is in place.

[0025] Furthermore, when the height difference between the vehicle body and the cargo box is less than or equal to 20cm, the laser beam emitted by the laser sensor 4 located on the vehicle body axis is used to adjust the top fairing. Furthermore, when the height difference between the vehicle body and the cargo box is greater than 20cm, the laser beam emitted by the laser sensors 4 located on both sides of the vehicle body axis is used to adjust the top fairing.

[0026] On the other hand, a truck is provided that includes any of the electric fairing assemblies described above.

[0027] By adopting the above technical solution, the problem of manual adjustment by users has been solved. It can be continuously adjusted within a certain angle to ensure that the vehicle body and cargo box match, and users can precisely adjust the angle of the fairing.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
