Description

Technical Field

[0001] The present application relates to the field of engine technology, and in particular to an air intake device capable of adjusting the air intake amount and a method of using the same. Background Art

[0002] The air intake duct is one of the important components of a vehicle. The engine draws enough air for its work through the air intake duct. Usually, the air intake duct is rectangular, with an air intake port of a certain area on the side. The thickness of the air intake duct in the front and rear directions is generally 100mm. The air intake duct is installed on the sheet metal of the rear panel of the cab and protrudes from the rear panel of the cab. During the driving of the vehicle, the area of ​​the air intake port remains fixed.

[0003] State 1: Usually when the engine is working, it needs to absorb a large amount of air through the intake duct. The intake duct is provided with an intake port of a certain area to meet the needs of the engine. However, due to the limitation of the layout space, the intake port area of ​​the intake duct is also constrained and cannot be increased to the maximum. Under normal circumstances, the intake port flow rate is relatively high and the air flow resistance of the intake system is large, which affects the engine power.

[0004] State 2: When the vehicle length meets the regulatory restrictions, in order to achieve maximum transportation efficiency, the vehicle cargo box needs to meet the maximum length. At this time, the cab needs to meet the indoor space requirements. That is, the cab length is certain, and the engine selection is determined. The air intake volume, that is, the thickness of the air intake duct is determined. Therefore, during the layout design, sufficient clearance must be reserved between the air intake duct and the front box panel to prevent the cab and the air intake duct from interfering with and wearing the cargo box during driving.

[0005] However, in the actual modification process, in order to pursue the maximum cargo box length, the modification factory reserves a small gap between the front box of the cargo box and the air intake duct, resulting in interference and wear between the air intake duct and the cargo box plate during the journey. Summary of the Invention

[0006] The embodiments of the present application provide an air intake duct device with adjustable air intake volume and a method for use thereof, so as to solve the problem in the related art that the air inlet area of ​​the existing air intake duct is fixed, resulting in insufficient air intake when the engine requires a large air intake volume, and the existing air intake duct is easily collided with the cargo box, resulting in damage to the air intake duct or reduction in the volume of the air intake duct during manufacturing, thereby causing a reduction in the air intake volume.

[0007] In a first aspect, an embodiment of the present application provides an air intake device capable of adjusting the amount of air intake, comprising:

[0008] An air intake mechanism, the air intake mechanism comprising a first air intake housing and a second air intake housing which are nested with each other, an air intake cavity being formed between the first air intake housing and the second air intake housing;

[0009] An adjusting mechanism is provided between the first air intake housing and the second air intake housing, and can make the second air intake housing slide into or out of the first air intake housing to change the size of the air intake cavity and adjust the air intake amount;

[0010] Furthermore, when the vehicle is driving on a bumpy road, the width of the air intake mechanism is reduced, and the gap between the air intake mechanism and the cargo box is increased, thereby reducing the risk of wear and interference between the air intake mechanism and the cargo box.

[0011] In some embodiments, the adjustment mechanism includes a first adjustment component disposed between a top portion of the first air intake housing and a top portion of the second air intake housing, and a second adjustment component disposed between a bottom portion of the first air intake housing and a bottom portion of the second air intake housing.

[0012] In some embodiments, the first adjustment assembly and the second adjustment assembly each include an auxiliary sliding assembly for assisting the sliding of the second air intake housing and a driving mechanism for driving the second air intake housing to slide along the width direction of the first air intake housing.

[0013] In some embodiments, the first adjustment assembly includes an auxiliary sliding assembly for assisting the sliding of the second air intake housing and a driving mechanism for driving the second air intake housing to slide along the width direction of the first air intake housing;

[0014] The second adjustment assembly includes an auxiliary sliding assembly for assisting the sliding of the second air intake housing.

[0015] In some embodiments, the auxiliary sliding assembly includes a slide rail disposed on the inner wall of the first air intake housing and a slider disposed on the outer wall of the second air intake housing facing the first air intake housing and cooperating with the slide rail.

[0016] In some embodiments, the driving mechanism includes a connecting plate provided on the inner wall of the first air inlet housing, two limiting plates provided on a side of the connecting plate away from the first air inlet housing, and a motor provided on one side of the limiting plate;

[0017] A lead screw is provided between the two limit plates, and one end of the lead screw is drivingly connected to the output shaft of the motor;

[0018] The lead screw is provided with a driving plate connected with the second air intake housing.

[0019] In some embodiments, the first air inlet housing and the second air inlet housing are both open at their respective ends adjacent to each other;

[0020] One end of the opening of the second air intake housing is inserted into the first air intake housing through the open end of the first air intake housing.

[0021] In some embodiments, the system further includes a body controller, an air intake mechanism controller, and sensors for sensing vehicle status.

[0022] A second aspect of the present application provides a method for using an air intake device capable of adjusting air intake volume, comprising the following steps:

[0023] When it is necessary to reduce the air intake volume or reduce the width of the air intake mechanism, the motor is used to drive the lead screw to rotate, and the lead screw drives the second air intake housing to move toward the first air intake housing through the drive plate;

[0024] When the air intake volume needs to be increased, the motor is used to drive the lead screw to rotate, and the lead screw drives the second air intake housing to move in a direction away from the first air intake housing through the drive plate.

[0025] In some embodiments, a movement number threshold is set for the controller. When the threshold is greater than the specified value, the controller starts the motor to move the drive plates in the first adjustment component and the second adjustment component to abut against the limit plate.

[0026] The beneficial effects of the technical solution provided by this application include:

[0027] When the vehicle enters acceleration or climbing mode from normal driving, the engine needs to increase the intake volume. At this time, the driver presses the switch, and the second intake duct slides out in the direction away from the first intake housing under the drive of the adjustment mechanism, so that the intake air cavity is enlarged, thereby increasing the intake port area of ​​the intake duct, increasing the intake volume, helping to reduce the engine speed and increase power.

[0028] When the vehicle enters deceleration and downhill mode from normal driving, the engine needs to reduce the intake volume. At this time, the driver presses the switch in reverse, and the second intake housing slides toward the first intake housing under the drive of the adjustment mechanism, reducing the intake cavity and thus reducing the intake port area of ​​the intake duct, reducing the engine's intake volume, helping to reduce engine speed, reduce power, and reduce vehicle speed.

[0029] When the vehicle enters a bumpy road, the cab will continuously tilt forward and backward along with the potholes on the road. For box-type trucks, the fixed mechanical mechanism on the rear wall of the cab will dynamically interfere with the cargo box, and may even cause wear of the air intake mechanism. At this time, the driver can press the switch in reverse, and the second air intake housing will slide in toward the first air intake housing under the drive of the adjustment mechanism, so that the air intake cavity is reduced, thereby reducing the air intake area of ​​the intake duct, reducing the engine's air intake volume, and helping to reduce the engine speed, power, and vehicle speed. Since the second air intake housing slides into the first intake housing, the width of the air intake mechanism is reduced, the gap between the air intake mechanism and the cargo box is increased, and the risk of wear and interference between the air intake mechanism and the cargo box is reduced.

[0030] By using an intake mechanism that can change the air intake volume and width, the volume of the intake cavity is increased when the vehicle needs a large air intake to increase the speed, so that the air intake volume is increased and the power of the engine is improved. When the vehicle is decelerating, the volume of the intake cavity is reduced, the air intake volume is reduced, and the power of the engine is reduced, thereby improving the flexibility of the intake mechanism to assist in various driving modes. When the cab and the cargo box dynamically interfere, the width of the intake mechanism is reduced so that the intake mechanism meets the clearance requirement between the cab and the cargo box, thereby preventing collision. The safety and life of the intake mechanism are improved, and the existing fixed intake mechanism is avoided, which cannot change the air intake volume to assist driving and causes collision wear.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] An embodiment of the present application provides an air intake duct device with adjustable air intake volume and a method for use thereof, which can solve the problem that the air inlet area of ​​the existing air intake duct is fixed, resulting in insufficient air intake when the engine requires a large air intake volume, and the existing air intake duct is easily collided with the cargo box, resulting in damage to the air intake duct or reducing the volume of the air intake duct during manufacturing, thereby causing a reduction in air intake volume.

[0042] See also Figure 1-7 As shown, a first aspect of an embodiment of the present application provides an air intake device capable of adjusting the air intake amount, comprising:

[0043] The air intake mechanism includes a first air intake housing 1 and a second air intake housing 2 which are nested with each other, and an air intake cavity 3 is formed between the first air intake housing 1 and the second air intake housing 2;

[0044] The regulating mechanism is provided between the first air intake housing 1 and the second air intake housing 2, and can make the second air intake housing 2 slide into or out of the first air intake housing 1 to change the size of the air intake cavity 3 and adjust the air intake amount.

[0045] The cavity enclosed by the first air intake housing 1 and the second air intake housing 2 is the air intake cavity 3. The length, width and height of the second air intake housing 2 are all smaller than the first air intake housing 1, so that the second air intake housing 2 can be inserted into the first air intake housing 1, and the second air intake housing 2 can slide into and out of the first air intake housing 1.

[0046] Among them, the first air intake shell 1 and the second air intake shell 2 are shell structures with one end open. The open ends of the first air intake shell 1 and the second air intake shell 2 correspond to each other, so that the open end of the second air intake shell 2 slides in and out from the open end of the first air intake shell 1.

[0047] An adjustment mechanism is provided between the first air intake housing 1 and the second air intake housing 2, which allows the second air intake housing 2 to actively slide out and slide in, wherein the first air intake housing 1 and the second air intake housing 2 can slide laterally, so that the first air intake housing 1 is connected to the cab, and the second air intake housing 2 is connected to the cargo box, wherein the first air intake housing 1 and the second air intake housing 2 can also slide longitudinally, so that one end of the first air intake housing 1 and the second air intake housing 2 are both connected to the cargo box, and the other end of the first air intake housing 1 and the second air intake housing 2 are both connected to the cab.

[0048] Among them, air intake ports are both provided on the first air intake housing 1 and the second air intake housing 2. A switch can be set in the cab, and the motor 13 in the adjustment mechanism drives and controls the second air intake housing 2 to slide into or out of the first air intake housing 1. Sensors, body controllers, air intake mechanism controllers and corresponding logic software can also be used to automatically sense the driving status and automatically control the adjustment.

[0049] Take the example of setting a switch in the cab to send a signal to the motor 13 to control the second air intake housing 2 to slide into or out of the first air intake housing 1:

[0050] When the vehicle enters acceleration or climbing mode from normal driving, the engine needs to increase the air intake. At this time, the driver presses the switch, and the second air intake housing 2 slides out in the direction away from the first air intake housing 1 under the drive of the adjustment mechanism, so that the air intake cavity 3 is enlarged, thereby increasing the air intake area of ​​the intake duct, increasing the air intake volume, helping to reduce the engine speed and increase power.

[0051] When the vehicle enters deceleration and downhill mode from normal driving, the engine needs to reduce the intake volume. At this time, the driver presses the switch in the opposite direction, and the second air intake housing 2 slides in the direction close to the first air intake housing 1 under the drive of the adjustment mechanism, so that the air intake cavity 3 is reduced, thereby reducing the intake port area of ​​the intake duct, reducing the engine's intake volume, helping to reduce the engine speed, reduce power, and reduce vehicle speed.

[0052] When the vehicle enters a bumpy road, the cab will continuously tilt forward and backward along with the potholes on the road. For a box truck, the fixed mechanical mechanism on the rear wall of the cab will dynamically interfere with the cargo box, and may even cause wear of the air intake mechanism. At this time, the driver can press the switch in reverse, and the second air intake shell 2 will slide in toward the first air intake shell 1 under the drive of the adjustment mechanism, so that the air intake cavity 3 is reduced, thereby reducing the air intake area of ​​the air intake duct, reducing the air intake volume of the engine, and helping to reduce the engine speed, reduce power, and reduce vehicle speed. Since the second air intake shell 2 slides into the first air intake shell 1, the width of the air intake mechanism is reduced, and the gap between the air intake mechanism and the cargo box is increased, reducing the risk of wear and interference between the air intake mechanism and the cargo box.

[0053] By using an air intake mechanism that can change the air intake volume and width, the volume of the air intake chamber 3 is increased when the vehicle needs a large air intake to increase the speed, so that the air intake volume is increased and the power of the engine is improved. When the vehicle is decelerating, the volume of the air intake chamber 3 is reduced, so that the air intake volume is reduced and the power of the engine is reduced, thereby improving the flexibility of the air intake mechanism to assist in various driving modes. When the cab and the cargo box dynamically interfere, the width of the air intake mechanism is reduced so that the air intake mechanism meets the clearance requirement between the cab and the cargo box, so that no collision occurs, thereby improving the safety and life of the air intake mechanism and avoiding the existing fixed air intake mechanism, which is unable to change the air intake volume to assist driving and causes collision wear.

[0054] In some optional embodiments, see Figure 1-7 As shown, in the air intake duct device with adjustable air intake volume, the adjustment mechanism includes a first adjustment component arranged between the top of the first air intake housing 1 and the top of the second air intake housing 2, and a second adjustment component arranged between the bottom of the first air intake housing 1 and the bottom of the second air intake housing 2. Through the first adjustment component and the second adjustment component, the second air intake housing 2 can slide into or out of the first air intake housing 1.

[0055] When the first air intake housing 1 and the second air intake housing 2 slide horizontally, the first adjustment assembly is located at the top and the second adjustment assembly is located at the bottom. When the first air intake housing 1 and the second air intake housing 2 slide longitudinally, the first adjustment assembly is located on the left and the second adjustment assembly is located on the right.

[0056] In some optional embodiments, see Figure 1-7 As shown, in the air intake duct device with adjustable air intake volume, the first adjustment component and the second adjustment component both include an auxiliary sliding component for assisting the sliding of the second air intake housing 2 and a driving mechanism for driving the second air intake housing 2 to slide along the width direction of the first air intake housing 1.

[0057] In this embodiment, the auxiliary sliding assembly includes a slide rail 11 arranged on the inner wall of the first air intake housing 1 and a slider 21 arranged on the outer wall of the second air intake housing 2 facing the first air intake housing 1 and cooperating with the slide rail 11, and the slider 21 is fixedly connected to the second air intake housing 2.

[0058] In this embodiment, the driving mechanism includes a connecting plate 12 arranged on the inner wall of the first air intake housing 1, two limit plates 14 arranged on the side of the connecting plate 12 away from the first air intake housing 1, and a motor 13 arranged on one side of the limit plate 14. A screw 16 is arranged between the two limit plates 14, one end of the screw 16 is transmission-connected to the output shaft of the motor 13, and a driving plate 17 connected to the second air intake housing 2 is arranged on the screw 16.

[0059] When it is necessary to drive the second air intake housing 2 to slide in or out of the first air intake housing 1, the motor 13 drives the screw 16 to rotate, and the screw 16 passes through the drive plate 17 and is threadedly connected to the drive plate 17, so that the drive plate 17 can move along the width direction of the screw 16. The drive plate 17 is fixedly connected to the second air intake housing 2, so that the drive plate 17 drives the second air intake housing 2 to slide in or out of the first air intake housing 1, and the slider 21 assists in sliding on the slide rail 11 to prevent the second air intake housing 2 from tilting when sliding out or in, resulting in the second air intake housing 2 being unable to slide out or in.

[0060] Both sides of the first air intake housing 1 and the second air intake housing 2 are driven by the motor 13 to drive the screw 16 to drive the second air intake housing 2 to move. After long-term use, the first adjustment component and the second adjustment component will become asynchronous. The controller is used to set the movement number threshold. When the threshold is greater than a certain set value, the controller sends a signal to start the motor 13. The motor 13 outputs power to move the drive plate 17 to the limit plate 14 to ensure that the upper and lower screws 16 work synchronously.

[0061] In some optional embodiments, see Figure 1-7 As shown, in the intake duct device with adjustable air intake volume, the first adjusting component includes an auxiliary sliding component for assisting the sliding of the second air intake housing 2 and a driving mechanism for driving the second air intake housing 2 to slide along the width direction of the first air intake housing 1, and the second adjusting component includes an auxiliary sliding component for assisting the sliding of the second air intake housing 2.

[0062] In this embodiment, the auxiliary sliding assembly includes a slide rail 11 provided on the inner wall of the first air intake housing 1 and a slider 21 provided on the outer wall of the second air intake housing 2 facing the first air intake housing 1 and cooperating with the slide rail 11 .

[0063] In this embodiment, the driving mechanism includes a connecting plate 12 arranged on the inner wall of the first air intake housing 1, two limit plates 14 arranged on the side of the connecting plate 12 away from the first air intake housing 1, and a motor 13 arranged on one side of the limit plate 14. A screw 16 is arranged between the two limit plates 14, one end of the screw 16 is transmission-connected to the output shaft of the motor 13, and a driving plate 17 connected to the second air intake housing 2 is arranged on the screw 16.

[0064] When it is necessary to drive the second air intake housing 2 to slide in or out of the first air intake housing 1, the motor 13 drives the screw 16 to rotate, and the screw 16 passes through the drive plate 17 and is threadedly connected to the drive plate 17, so that the drive plate 17 can move along the width direction of the screw 16. The drive plate 17 is fixedly connected to the second air intake housing 2, so that the drive plate 17 drives the second air intake housing 2 to slide in or out of the first air intake housing 1, and the slider 21 assists in sliding on the slide rail 11 to prevent the second air intake housing 2 from tilting when sliding out or in, resulting in the second air intake housing 2 being unable to slide out or in.

[0065] The second adjusting assembly only has auxiliary sliding gripping, and the motor 13 in the first adjusting assembly drives the lead screw 16 to rotate to drive the driving plate 17 and the second air intake housing 2 to move.

[0066] In some optional embodiments, see Figure 5 As shown, in the air intake duct device with adjustable air intake volume, the ends of the first air intake housing 1 and the second air intake housing 2 close to each other are both open, and the open end of the second air intake housing 2 is inserted into the first air intake housing 1 through the open end of the first air intake housing 1.

[0067] In some optional embodiments, the air intake device with adjustable air intake volume includes a body controller, an air intake mechanism controller and a sensor for sensing the vehicle status. A switch can be set in the cab to drive the motor 13 in the adjustment mechanism to control the second air intake housing 2 to slide in or out of the first air intake housing 1. Sensors, body controllers, air intake mechanism controllers and corresponding logic software can also be used to automatically sense the driving status and automatically control the adjustment.

[0068] When a switch is used to send a signal to the motor 13 , the motor 13 drives the lead screw 16 to move in forward and reverse directions, so that the second air intake housing 2 slides in or out of the first air intake housing 1 .

[0069] When the vehicle body controller, intake mechanism controller, sensor, and logic software are used to automatically sense the driving state, the sensor is preferably a displacement sensor, which is arranged on the intake mechanism to detect the distance between the cargo box and the intake mechanism. The intake mechanism controller is grounded at one end and connected to the vehicle power supply at the other end. The switch controls the opening and closing of the circuit to control the operation of the system. The vehicle body controller is connected to the vehicle network via the CAN bus, reads signals from other vehicle controllers, and sends signals to the intake mechanism controller. The intake mechanism controller is connected to the vehicle network via the CAN bus, communicates with the vehicle body controller, reads the body controller signals, and converts the required signals to the motor 13.

[0070] See also Figure 1-7 As shown, a first aspect of an embodiment of the present application provides an air intake device capable of adjusting the air intake amount, comprising the following steps:

[0071] Step 1: When it is necessary to reduce the air intake volume or reduce the width of the air intake mechanism, the motor 13 is used to drive the screw 16 to rotate, and the screw 16 drives the second air intake housing 2 to move toward the first air intake housing 1 through the drive plate 17.

[0072] Step 2: When the air intake volume needs to be increased, the motor 13 is used to drive the lead screw 16 to rotate, and the lead screw 16 drives the second air intake housing 2 to move in a direction away from the first air intake housing 1 through the drive plate 17 .

[0073] When the vehicle enters braking mode from normal driving, the cab tilts back and forth continuously in the direction of vehicle travel in braking mode, and the vehicle slows down and stops. At this time, the second air intake housing 2 can automatically retract in advance to reduce the air intake area of ​​the air intake duct, thereby reducing the air intake volume of the engine, helping to reduce the engine speed, reduce power, and reduce vehicle speed.

[0074] When the switch is pressed, when the vehicle braking system enters the working state, the body controller reads the braking system controller signal. When the signal is greater than the design threshold, the intake mechanism controller controls the motor 13 to start working, and the motor 13 outputs power to drive the second intake housing 2 to retract along the slide rail 11. When exiting the braking mode, the body controller reads the braking system controller signal. When the signal is less than the design threshold, the intake mechanism controller starts the motor 13, and the motor 13 outputs power to push the second intake housing 2 to extend along the slide rail 11, thereby increasing the intake port area, increasing the intake volume, and improving the engine power.

[0075] When the vehicle enters the acceleration mode from normal driving, the cab tilts backward in the vehicle's forward direction in the acceleration mode, and the vehicle's driving speed increases. At this time, the second air intake housing 2 can automatically extend in advance to increase the air intake area of ​​the air intake duct, thereby increasing the engine's intake volume, helping to increase the engine speed and improve power.

[0076] Press the switch, when the vehicle acceleration system enters the working state, the body controller reads the acceleration system controller signal, when the signal is greater than the design threshold, the intake mechanism controller controls the starting motor 13 to work, the motor 13 outputs power to push the second air intake shell 2 to extend along the slide rail 11, when exiting the acceleration mode, the body controller reads the acceleration system controller signal, when the signal is less than the design threshold, the intake mechanism controller controls the motor 13 to start working, the motor 13 outputs power to push the second air intake shell 2 to retract along the slide rail 11, reducing the air intake area, and increasing it to the set initial air intake area to meet the engine power.

[0077] When the vehicle turns from normal driving, the cab will tilt left and right. At this time, the second air intake housing 2 can automatically retract in advance to reduce the air intake area of ​​the air intake duct, thereby increasing the air intake volume of the engine, helping to reduce the engine speed, reduce power, and reduce vehicle speed.

[0078] Press the switch, and when the vehicle enters a turn, the body controller reads the turning angle controller signal. When the signal is greater than the design threshold, the intake mechanism controller controls the motor 13 to start working, and the motor 13 outputs power to push the second intake housing 2 to retract along the slide rail 11. When the vehicle is traveling in a straight line, the body controller reads the turning angle system controller signal. When the signal is less than the design threshold, the intake mechanism controller controls the motor 13 to start working, and the motor 13 outputs power to push the second intake housing 2 to retract along the slide rail 11, reducing the intake port area and increasing it to the set initial intake area to meet the engine power.

[0079] When the vehicle enters a continuously bumpy road from normal driving, the cab tilts back and forth continuously in the vehicle's forward direction. At this time, the second air intake housing 2 can automatically retract in advance to reduce the air intake area of ​​the air intake duct, thereby increasing the engine's air intake volume, helping to reduce the engine speed, reduce power, and reduce vehicle speed.

[0080] Press the switch. When the vehicle enters a continuously bumpy road, the air intake mechanism controller reads the displacement sensor signal. When the signal is greater than the design threshold, the air intake mechanism controller controls the motor 13 to start working. The motor 13 outputs power to push the second air intake housing 2 to retract along the slide rail 11. When the vehicle enters a flat road, the air intake mechanism controller controls the displacement sensor signal. When the signal is less than the design threshold, the air intake mechanism controller controls the motor 13 to start working. The motor 13 outputs power to push the second air intake housing 2 to extend along the slide rail 11, increasing it to ensure the set initial air intake area to meet the engine power.

[0081] In some optional embodiments, in the intake duct device with adjustable air intake volume, a movement number threshold is set for the controller. When the threshold is greater than the specified value, the controller starts the motor 13 to move the drive plates 17 in the first adjustment component and the second adjustment component to abut the limit plate 14.

[0082] Both sides of the first air intake housing 1 and the second air intake housing 2 are driven by the motor 13 to drive the screw 16 to drive the second air intake housing 2 to move. After long-term use, the first adjustment component and the second adjustment component will become asynchronous. The controller is used to set the movement number threshold. When the threshold is greater than a certain set value, the controller sends a signal to start the motor 13. The motor 13 outputs power to move the drive plate 17 to the limit plate 14 to ensure that the upper and lower screws 16 work synchronously.

[0083] The working principle and process of this application:

[0084] When the vehicle enters braking mode from normal driving, the cab tilts back and forth continuously in the direction of vehicle travel in braking mode, and the vehicle slows down and stops. At this time, the second air intake housing 2 can automatically retract in advance to reduce the air intake area of ​​the air intake duct, thereby reducing the air intake volume of the engine, helping to reduce the engine speed, reduce power, and reduce vehicle speed.

[0085] When the switch is pressed, when the vehicle braking system enters the working state, the body controller reads the braking system controller signal. When the signal is greater than the design threshold, the intake mechanism controller controls the motor 13 to start working, and the motor 13 outputs power to drive the second intake housing 2 to retract along the slide rail 11. When exiting the braking mode, the body controller reads the braking system controller signal. When the signal is less than the design threshold, the intake mechanism controller starts the motor 13, and the motor 13 outputs power to push the second intake housing 2 to extend along the slide rail 11, thereby increasing the intake port area, increasing the intake volume, and improving the engine power.

[0086] When the vehicle enters the acceleration mode from normal driving, the cab tilts backward in the vehicle's forward direction in the acceleration mode, and the vehicle's driving speed increases.
