Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Fig. 1 is a first side view of a pod provided by the embodiment of the present invention, fig. 2 is a second side view of a pod provided by the embodiment of the present invention, fig. 3 is an electrical connection schematic diagram of a pod control system provided by the embodiment of the present invention, as shown in fig. 1-3, the pod control system includes a pan motor 10, a rotating motor 20, a side pod 30, a secondary pod 40, a slide rail 50 and a controller 60, the side pod 30 and the secondary pod 40 are arranged along a first direction (X direction shown in the figure) and each extend along a second direction (Y direction shown in the figure), the slide rail 50 extends along the first direction X, the first direction X intersects the second direction Y, the pan motor 10 is located on the slide rail 50 and is electrically connected with the secondary pod 40 for driving the secondary pod 40 to move along the first direction X on the slide rail 50, the rotating motor 20 is electrically connected with the side pod 30 and the secondary pod 40 for driving the side pod 30 and the secondary pod 40 to rotate, and the motor controller 60 is electrically connected with the rotating motor 10 and the rotating motor 20 for controlling the pan motor 10 and the secondary pod 40 according to the adjustment of the pan motor's rotation conditions or the adjustment of the rotation angle of the side pod 40 and the vehicle's speed, respectively.
Specifically, the side fairings 30 are located on both sides of the vehicle body for reducing wind resistance during operation of the vehicle. The extension length of the auxiliary pod 40 can be adjusted by moving left and right on the slide rail 50 to reduce wind resistance. The translation motor 10 is located on the sliding rail 50 and is electrically connected with the secondary air guide sleeve 40, so that the translation motor 10 can drive the secondary air guide sleeve 40 to move along the first direction X on the sliding rail 50, and change in length of the secondary air guide sleeve 40 is achieved. Illustratively, when the translation motor 10 drives the secondary side guide cover 40 to move leftwards on the slide rail 50, the secondary side guide cover 40 can be extended to reduce wind resistance, and when the translation motor 10 drives the secondary side guide cover 40 to move rightwards on the slide rail 50, the secondary side guide cover 40 can be shortened to prevent the secondary side guide cover 40 from colliding with a trailer.
Specifically, the rotating electrical machine 20 is connected with the side air guide sleeve 30 and the auxiliary side air guide sleeve 40 through the first air guide sleeve fixing bracket 110 and the second air guide sleeve fixing bracket 120 respectively, and the shaft coupling drives the brackets to rotate, so that the angles of the side air guide sleeve 30 and the auxiliary side air guide sleeve 40 are adjusted, that is, the rotating electrical machine 20 can drive the side air guide sleeve 30 to rotate to perform angle adjustment, and can also drive the auxiliary side air guide sleeve 40 to rotate to perform angle adjustment, so that wind resistance can be reduced, and fuel consumption can be reduced.
The side pod 30 and the sub-side pod 40 both rotate around the Y axis.
As a possible implementation, when the vehicle condition information is that the running speed is small, the influence of the air resistance on the vehicle performance is small, so the controller 60 can control the translation motor 10 to adjust the length of the secondary side air guide sleeve 40 to improve the air flow, so as to reduce the wind resistance.
As another possible embodiment, the controller 60 controls the translation motor 10 to adjust the length of the secondary side pod 40 and controls the rotation motor 20 to adjust the angles of the side pod 30 and the secondary side pod 40. For example, when the vehicle is traveling at a high speed and the cargo box height is relatively fixed, the vehicle optimizes aerodynamic performance by adjusting the angle and length of the pod, reducing windage and fuel consumption.
As yet another possible embodiment, the controller 60 controls the pan motor 10 to adjust the length of the secondary side pod 40 according to the vehicle condition information. For example, when the vehicle is running at a high speed and the steering wheel angle change rate is high, the vehicle may be in overtaking or sharp turning conditions, and at this time, the length of the air guide sleeve needs to be adjusted at the same time, so as to protect the air guide sleeve, and prevent the air guide sleeve from colliding with the trailer.
It should be noted that, specific adjustment parameters about the length and angle of the pod may be adjusted according to model calculation.
It should be noted that the displacement of the translation motor and the angle of the rotation motor should satisfy the following relationship:
sinθ(Lx+X)+Lx≤2550;
Wherein L x is the length of the side air guide sleeve 30 along the first direction X, X is the displacement of the translation motor 10, L y is the width of the side air guide sleeve 30 along the second direction Y, and θ is the rotation angle of the rotation motor 20.
When the vehicle speed is lower than the vehicle speed threshold value, the translation motor and the rotary motor are started to restore the dome to the original positions. When the speed change rate of the whole vehicle is overlarge and the steering wheel rotation angle is overlarge, the whole vehicle is judged to be in the overtaking or turning working condition, and the translation motor and the rotating motor are started so as to enable the air guide sleeve to recover to the original position, and the air guide sleeve is prevented from colliding with the trailer.
According to the guide cover control system provided by the embodiment of the invention, the controller is respectively and electrically connected with the translation motor and the rotary motor, the translation motor is controlled to adjust the length of the auxiliary guide cover according to the vehicle working condition information, and/or the rotary motor is controlled to adjust the angles of the auxiliary guide cover and the auxiliary guide cover, so that the controller can intelligently adjust the length and/or the angle of the guide cover according to the vehicle working condition information, further the guide cover can be automatically adjusted, the wind resistance is reduced through the guide cover with proper angle and length, and the fuel economy of the whole vehicle is improved.
Alternatively, with continued reference to fig. 1-3, the controller 60 is electrically connected to the vehicle speed detection sensor 70 and the steering wheel angle sensor 80, respectively, for determining vehicle condition information based on the sensed signals of the vehicle speed detection sensor 70 and the steering wheel angle sensor 80.
Specifically, the controller 60 may obtain the vehicle speed information sensed by the vehicle speed detection sensor 70 and the steering wheel angle information sensed by the steering wheel angle sensor 80, and further determine the vehicle condition information according to the vehicle speed information and the steering wheel angle information, so as to adjust the length and/or angle of the air guide sleeve according to the vehicle condition information, and further realize automatic adjustment of the air guide sleeve.
For example, vehicle speed information and steering wheel angle information may be communicated back to the controller via a telematics box (TELEMATICS BOX, TBOX).
It should be noted that, the corresponding relationship between the vehicle speed information, the steering wheel angle information, the pod extension length information and the angle information is stored in the controller 60, so that the parameter information sensed in real time according to the vehicle speed detection sensor 70 and the steering wheel angle sensor 80 can be matched with the pod extension length information and the angle information, and further the translational motor 10 and the rotary motor 20 can be controlled to enable the pod to reach the target length and the target angle, so as to realize intelligent control of the pod.

Specifically, the displacement sensor 90 is located at the first side of the sliding rail 50, so that on one hand, the maximum extension length of the secondary side air guide sleeve 40 can be detected, and on the other hand, the distance between the secondary side air guide sleeve 40 and the trailer can be detected in real time through the arrangement of the displacement sensor 90, so that the gap distance between the secondary side air guide sleeve 40 and the trailer is prevented from being too small, and further mutual interference is caused, and the running of the vehicle is affected.
Alternatively, with continued reference to fig. 1-3, the displacement sensor 90 comprises a laser displacement sensor. The laser displacement sensor can realize non-contact measurement in a displacement manner, and has high measurement speed and high detection precision.
1-3, The pod control system further includes a travel switch 100, the travel switch 100 is located on a second side of the sliding rail 50 along the first direction X, and the controller 60 is further electrically connected to the travel switch 100 for controlling the translation motor 10 and the rotation motor 20 to stop working when the secondary pod 40 contacts the travel switch 100.

When the secondary side guide cover 40 contacts with the travel switch 100, the travel switch 100 is in an off state, and the controller 60 controls the translation motor 10 and the rotary motor 20 to stop working so as to ensure that the guide cover moves according to a preset position and travel, and prevent the guide cover from being separated from the slide rail 50, so that the problems of tripping, sliding and the like are solved.
Optionally, with continued reference to fig. 3, the controller 60 may include a signal conditioning unit 200, where the signal conditioning unit 200 is electrically connected to the controller 60, and is configured to receive an output signal of the controller 60, and perform conditioning to output conditioning signals to the translation motor 10 and the rotation motor 20 according to the output signal of the controller 60.
Specifically, the signal conditioning unit 200 may include a pulse width modulation module, a semiconductor switch, a voltage control module, and a current limiter, which are electrically connected in sequence. The PWM is a module integrated based on PWM technology (Pulse Width Modulation, PWM) and is used for implementing PWM of the output signal of the controller, and the semiconductor switch is controlled by the PWM modulated signal to be turned on and off, and the semiconductor switch may be, for example, an insulated gate bipolar transistor (Insulated Gate Bipolar Transistor, IGBT). The voltage control module is a module formed by integrating a step-down chopper circuit. The signal regulating unit is connected with the controller through the pulse width modulation module and connected with the translation motor and the rotating motor through the current limiter. In the signal adjusting unit, the pulse width modulation module is connected with the semiconductor switch, the semiconductor switch is connected with the voltage control module, and the voltage control module is connected with the current limiter. The current limiter can limit the current in the circuit and can play a role in protecting the translation motor and the rotation motor.

When the semiconductor switch is turned on, the first intermediate signal is transmitted to the voltage control module, the voltage control module performs step-down processing on the first intermediate signal through the step-down chopper circuit to obtain a second intermediate signal after voltage reduction, the second intermediate signal is transmitted to the current limiter, the current limiter performs current limiting processing on the second intermediate signal to obtain an adjusting signal after current reduction, and the adjusting signal is transmitted to the translation motor 10 and the rotating motor 20 to ensure normal operation of the translation motor 10 and the rotating motor 20.

Specifically, the first translation motor 101 may drive the secondary pod 40 to slide on the first slide rail 501 along the first direction X, and the second translation motor 102 may drive the secondary pod 40 to slide on the second slide rail 502 along the first direction X, so that when one of the translation motors fails, the other motor still can work normally, and stability and reliability of the pod control system can be ensured. In other words, one of the first translation motor 101 and the second translation motor 102 may be a primary translation motor, and the other may be a backup translation motor to ensure normal driving of the secondary pod 40.
For example, the first translation motor 101 and the second translation motor 102 may operate simultaneously. It should be noted that, when the two translation motors simultaneously drive the same secondary side air guide sleeve 40, the working parameters of the two translation motors need to be the same, so as to ensure that the two translation motors operate synchronously, that is, the two translation motors drive the secondary side air guide sleeve 40 synchronously, which is beneficial to driving the secondary side air guide sleeve 40 to adjust the length along the first direction X.
