Description

Technical Field

[0002] A spoiler is a vehicle aerodynamic device that reduces the air turbulence and resistance generated when the vehicle is driving at high speed, which can save fuel, improve the stability of the vehicle and ensure driving safety. Among them, an active spoiler is a spoiler that can be dynamically adjusted according to the current vehicle operating conditions to change the spoiler effect, strength or other performance attributes. With the development of the automotive industry and the increasingly mature application of aerodynamics in the automotive industry, common spoiler devices on automobiles are installed on the back door, top, tail, and front of the tire. Common motion mechanism forms include pop-up, lifting and rotating types. However, with the application of existing aerodynamic devices, it is difficult to take into account the use requirements of other components under specific working conditions. For example, in southwest my country, long slope sections are more common. When driving under such road conditions, if the vehicle is braked for a long time, the brake lining will continue to generate heat due to friction. At this time, the spoiler in front of the tire restricts the air flow near the tire, which is not conducive to the cooling of the brake lining, thereby affecting the driving safety of the vehicle.

After confirming the control mode, the active spoiler driving module 9 drives the spoiler 2 and the water pipe nozzle assembly to move to the corresponding state.

[0040] The water pipe nozzle assembly in this embodiment includes a water pipe 5, a nozzle 4 and a washing liquid tank 6. Both ends of the water pipe 5 are respectively connected to the nozzle 4 and the washing liquid tank 6. The nozzle 4 is spaced apart from the brake lining 3. When the temperature of the brake lining 3 reaches a set threshold, the washing liquid in the washing liquid tank 6 is sprayed toward the brake lining 3 through the water pipe 5 and the nozzle 4, thereby cooling the brake lining 3.

[0041] In this embodiment, the spoiler 2 includes a frame 201, a motor 204 and a plurality of blades 202, wherein the plurality of blades 202 are rotatably arranged on the frame 201, and each adjacent two blades 202 are connected by a connecting rod 206, and both ends of the blades 202 are provided with a rotating shaft, and both ends of the frame 201 are provided with a side pressure plate 203, and the rotating shafts at both ends of the blades 202 are connected to the frame 201 through the side pressure plate 203, and the motor 204 is arranged on one side of the frame 201, and the motor 204 The output end is connected to the adjacent blade 202, a middle pressure plate 205 is provided in the middle of the frame 201, the motor 204 is connected to the frame 201 through the middle pressure plate 205, the control system drives the blade 202 to rotate through the motor 204 to change the state of the spoiler 2, the side pressure plate 203 is used to fix the rotating shafts at both ends of the blade 202, the middle pressure plate 205 is used to fix the motor 204 and the frame 201, and the blades 202 are connected by connecting rods to realize the rotation of multiple groups of blades 202.

[0042] In this embodiment, the number of blades 202 is three as an example.

[0043] This embodiment also provides a control method for an active spoiler device, which includes the following steps:

[0044] Step 1: When the state determination module 7 receives the control signal, the state determination module 7 determines the current state of the spoiler 2 and the water pipe nozzle assembly;

[0045] Step 2: After the current state of the spoiler 2 and the water pipe nozzle assembly is determined, the control mode determination module 8 selects and confirms the corresponding control mode according to the current state of the spoiler 2 and the water pipe nozzle assembly;

[0046] Step 3: After the control mode is confirmed, the active spoiler driving module 9 drives the spoiler 2 and the water pipe nozzle assembly to move to the corresponding state.

[0047] In the step 1 of the present embodiment, the control signal includes the vehicle speed of the speedometer, the braking frequency of the brake lining 3 and the temperature of the brake lining 3 .

[0048] In the present embodiment, the control modes of the control mode determination module 8 in step 2 include a first control mode, a second control mode, a third control mode and a fourth control mode.

[0049] In step 3 of the present embodiment, the states of the spoiler 2 include a spoiler state, a hidden state, and an air supply state. The mechanical principle diagrams of the state motion structure of the blade 202 of the spoiler 2 in the air supply state, the hidden state, and the spoiler state are respectively as shown in FIG. Figure 7 , Figure 8 and Fig. 9 The states of the water pipe nozzle assembly include a water spraying cooling state and a pause state. When the water pipe nozzle assembly is in the water spraying cooling state, the water pipe nozzle assembly sprays washing liquid onto the brake lining 3 for cooling. When the water pipe nozzle assembly is in the pause state, it stops spraying washing liquid onto the brake lining 3.

When the control mode of the control mode determination module 8 is the fourth control mode, the state of the spoiler 2 is the air supply state, and the state of the water pipe nozzle assembly is the water spray cooling state.

[0051] In this embodiment, when the average vehicle speed is less than 60 km / h and the brake lining temperature is less than 200°C, the control mode of the control mode determination module 8 is the first control mode. At this time, the vehicle speed is low, the spoiler effect is not obvious, the spoiler 2 is in a hidden state, and the water pipe nozzle assembly is in a paused state, which plays a self-protection role.

[0052] In this embodiment, when the average vehicle speed is greater than 60 km / h and the brake lining temperature is less than 200°C, the control mode of the control mode determination module 8 is the second control mode.

[0053] In this embodiment, when the temperature of the brake lining 3 is greater than 200°C, it is detected once every 1 minute, and the temperature is greater than 200°C for N consecutive times. When N<3, the spoiler 2 and the water pipe nozzle assembly maintain their original states. When N≥3, the control mode of the control mode determination module 8 is the third control mode. At this time, the state of the spoiler 2 enters the brake lining 3 air supply state, which plays a role in cooling the brake lining 3, and the state of the water pipe nozzle assembly is a paused state.

[0054] In this embodiment, when the temperature of the brake lining 3 is greater than 200°C, it is detected once every 1 minute, and the temperature is greater than 200°C for N consecutive times. When N≥5, the control mode of the control mode determination module 8 is the fourth control mode, and the active spoiler enters the brake lining 3 air supply state to cool the brake lining 3. At the same time, the water pipe and nozzle assembly start the water spray cooling state.
