TECHNICAL FIELD

[0001] The present application belongs to the technical field of trucks and accessories, and particularly relates to an electric flow guide cover assembly, an adjusting method and a truck. BACKGROUND

[0002] In the design and use of truck vehicles, the height difference between the vehicle body and the cargo box increases the overall vehicle wind resistance, thereby increasing fuel consumption. In order to solve this problem, various vehicle manufacturers generally use the design of a flow guide cover to compensate for the height difference, so that the vehicle body and the cargo box are matched. However, the general flow guide cover can only be matched with a cargo box of a certain height. Sometimes the user will replace the cargo box. Once the cargo box is too low or too high, the overall vehicle wind resistance will also increase, and the best effect of reducing fuel consumption cannot be achieved.

[0003] At present, some vehicle manufacturers have designed some manually adjustable flow guide covers. However, because the flow guide cover is assembled on the roof of the vehicle, it is not easy to operate, and it is difficult for the user to adjust. In addition, the user does not know how much angle to adjust, so the best effect of reducing fuel consumption cannot be achieved. Some vehicle manufacturers have designed electrically adjustable flow guide covers, which have solved the problem of user adjustment difficulty, but have not solved the problem of adjusting the angle. Therefore, the above solutions have not solved the best matching problem of the vehicle body and the cargo box, and cannot achieve the optimal state. SUMMARY

[0010] The control method is used for the electric fairing assembly, and the control method comprises the following steps: when a user starts the electric height adjusting mechanism to adjust the fairing, the laser sensor simultaneously starts to emit a red laser beam, and whether the fairing is adjusted to the position is judged by observing the position of the red laser beam irradiated on the cargo box.

[0019] As shown in Figure 1 The present application provides an electric deflector assembly, which comprises two side deflectors 1 arranged opposite to each other, a top layer deflector 2 is arranged on the side deflector 1, an electric height adjusting mechanism 3 for driving the top layer deflector 2 to rise and fall is arranged on the inner side of the top layer deflector 2; a laser sensor 4 is arranged on the end face of the top layer deflector 2 facing the cargo box; Further comprising a control unit, the control unit comprises a controller, the laser sensor 4 is in communication connection with the input end of the controller, and the output end of the controller is in communication connection with the driving motor in the electric height adjusting mechanism 3. Through the cooperation of the electric height adjusting mechanism 3 and the laser sensor 4, the problem of increased wind resistance of the whole vehicle caused by the mismatch between the traditional deflector and the cargo box height is effectively solved. The laser sensor 4 detects the height of the cargo box in real time and transmits the data to the controller, and the controller automatically controls the height of the top layer deflector 2 according to the information, so that the top layer deflector 2 always maintains the optimal matching state with the cargo box. The system realizes precise height adjustment, overcomes the difficulty of manual adjustment, and makes up for the deficiency of ordinary electric deflectors that cannot intelligently determine the adjustment angle. Finally, the wind resistance and fuel consumption are significantly reduced, and the economy and operation convenience of the whole vehicle are improved.

[0020] As shown in Figure 2 Specifically, the control unit comprises a controller, and the controller adopts STM32F103; A laser module comprising a laser sensor 4, the laser module and the controller are in communication connection to realize the transmission of high and low level control signals; The power drive module for controlling the driving motor is L298N, which is in communication connection with the controller to realize transmission of the PWM control signal, and controls the driving motor to work and thus realize lifting of the top fairing 2. The mobile phone APP is in communication connection with the controller through the Bluetooth module, and is used for remote control of the user end, and the Bluetooth module is HC-05 / 08.

[0021] The 12V power supply on the vehicle is reduced in voltage through the power circuit to provide stable DC voltage for the controller, the laser module, the power drive module and the Bluetooth module.

[0022] Further, the top fairing 2 extends downward at both sides to form extension parts, and the extension parts at both sides are overlapped with the upper end parts of the two side fairing plates 1 respectively. The gap between the fairing and the roof caused by lifting of the top fairing 2 can be compensated, so that the wind resistance coefficient is effectively reduced.

[0023] Further, the electric height adjusting structure comprises a driving motor and a screw nut pair, the screw in the screw nut pair is connected with the driving motor, a connecting rod member is hinged on the nut in the screw nut pair, the connecting end of the connecting rod member is hinged with the inner surface of the top fairing 2, and the driving motor drives the nut to move linearly on the screw and drives the top fairing 2 to lift through the connecting rod member. The combination of the screw nut pair and the connecting rod mechanism has high transmission efficiency and accurate positioning, and can realize stable and reliable lifting adjustment of the top fairing 2.

[0024] Preferably, the driving motor is a double-head motor, and the screw nut pair and the connecting rod member are both provided with two groups, the screws on the two groups of screw nut pairs are connected with the double-head motor respectively, the driving motor drives the nuts on the two groups of screw nut pairs to move away from or towards each other, and the two groups of connecting rod members are hinged on the nuts on the two groups of screw nut pairs respectively. The double-head motor synchronously drives the two groups of symmetrically distributed screw nut pairs and connecting rod mechanisms, which can realize bilateral synchronous and balanced lifting of the top fairing 2, effectively prevent jamming or structural deformation caused by uneven force on one side, and significantly improve the stability and reliability of the adjustment process.

[0025] Further, the laser sensor 4 is provided with three, and the three laser sensors 4 are arranged on the vehicle body axis and on both sides of the vehicle body axis respectively. Through symmetrical arrangement of the three laser sensors 4 along the vehicle body axis and on both sides, the height information of different positions of the cargo box can be synchronously collected to realize comprehensive perception and accurate measurement of the plane posture of the cargo box; based on multi-sensor data fusion, the system can more accurately calculate the height and angle required for adjustment of the fairing, and significantly improve the aerodynamic matching accuracy with the cargo box.

[0026] Another aspect provides a method for adjusting a deflector, the control method is used in any of the above-mentioned electric deflector assembly, the control method includes that when the user starts the electric height adjustment mechanism 3 to adjust the deflector, the laser sensor 4 simultaneously starts to emit a red laser beam, and the user determines whether the deflector is adjusted to the position by observing the position of the red laser beam irradiated on the container.

[0027] Further, the laser sensor 4 emits a red laser beam to irradiate on the top of the container, so as to ensure that the tangent of the rear edge of the deflector is in line with the top of the container, and the state is the adjustment to the position.

[0028] Further, when the height difference between the vehicle body and the container is less than or equal to 20 cm, the laser beam emitted by the laser sensor 4 located on the axis of the vehicle body is used to adjust the top deflector. Further, when the height difference between the vehicle body and the container is greater than 20 cm, the laser beams emitted by the laser sensors 4 located on both sides of the axis of the vehicle body are used to adjust the top deflector.
