Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a turbulence protection system for mining vehicles. Background Technology

[0002] Currently, heavy commercial vehicles typically have sun visors at the front of the cab, and mining vehicles also usually have sun visors located outside the cab. Some mining vehicles also have arc-shaped deflectors added to the top of the cab to achieve the basic functions of sunshade and water flow blocking.

[0003] However, the existing baffle structures of mining vehicles have obvious defects. First, they are limited in function, only able to provide basic functions such as sunshade and water protection, and cannot meet the multi-scenario usage needs of mining vehicles during outdoor operations. Second, they adopt a fixed mechanical installation structure, and the shape and angle cannot be adjusted after assembly, resulting in poor adaptability. It is difficult to make corresponding adjustments according to the operating status and cargo load of the mining vehicle. At the same time, they cannot solve practical problems such as high aerodynamic resistance, mineral dust, and protection of the cab from impact and rain during operation.

[0004] In view of this, this application proposes a mining vehicle turbulence protection system to solve the above-mentioned technical problems existing in the baffle structure of existing mining vehicles. Summary of the Invention

[0013] The controller is electrically connected to the rotary motor and the displacement motor respectively, so as to independently control the rotation of the rotary motor, the traction of the displacement motor, or control the two to work together.

[0014] Preferably, in the above technical solution, the rotary motor has a first position and a second position along the displacement guide rail; when the rotary motor is in the first position, it is located at the lower end of the displacement guide rail and is interfered with by the structural space of the cockpit cover, and the rotary motor drives the front baffle to rotate around its rotation axis by an angle of 180°; when the rotary motor is in the second position, it is pulled by the displacement motor to the top position of the displacement guide rail through the transmission belt, the structural space rotation interference of the cockpit cover on the front baffle is released, and the rotation angle of the front baffle driven by the rotary motor around its rotation axis is extended to 270°.

[0018] Preferably, in the above technical solution, the controller has a built-in torque calculation module and a vehicle resistance detection module. The controller obtains and judges the vehicle resistance when the mining vehicle is driving through the vehicle resistance detection module. At the same time, the controller calculates the adaptation parameters based on the loading height of the minerals in the cargo box of the mining vehicle using the torque calculation module, and adaptively controls the rotation angle of the rotary motor and the displacement distance of the displacement motor pulling the rotary motor, so that the front baffle is adjusted to the position with the lowest wind resistance of the whole vehicle.

[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0037] Unless otherwise specified, the experimental methods used in the following examples are conventional methods, and the materials and reagents used are commercially available. Unless otherwise specified, the equipment used in the experiments is well known to those skilled in the art.

[0038] The mining vehicle turbulence protection system of this invention is integrated into the upper cover of the mining vehicle's cab. Through the coordinated rotation of the rotary motor 2 and the traction of the displacement motor 3, precise adjustment of the angle and height of the front baffle 1 is achieved. This system adapts to the full range of operational needs of mining vehicles, including sunshade, rain protection, airflow guidance, impact prevention, and dust control. The system comprises a front baffle 1, a rotary motor 2, a displacement motor 3, a displacement guide rail 4, a transmission belt 5, and a controller. The specific structure, positional connections, and operational coordination of each component are as follows:

[0039] Front baffle 1: The front baffle 1 is an integral rigid plate structure, which is set at the front end of the mining vehicle's cab cover. It is the core component for realizing the functions of airflow disturbance, protection, and shielding. Specifically, it includes a plate surface, an arc surface, and a slope. The plate surface is a flat plate surface close to the cab, which serves as the main shielding surface for anti-impact and sunshade. The size of the plate surface is adapted to the lateral width of the front end of the cab cover. The slope surface is an inclined slope surface away from the cab, which serves as the main airflow guiding surface for airflow guidance and dust prevention. The inclination angle of the slope surface is adapted to the airflow direction when the mining vehicle is moving. The arc surface is a transition connection structure, integrally formed between the plate surface and the slope surface, realizing a smooth transition between the flat plate surface and the inclined slope surface, avoiding the formation of vortices in the airflow at the connection between the plate surface and the slope surface, reducing aerodynamic drag, and improving the overall mechanical strength of the structure.

[0040] Furthermore, the angle between the plate and the slope is 120°-150°. This angle range can ensure the airflow guidance effect of the inclined slope, so that the oncoming airflow when the mining vehicle is moving can be smoothly guided upward along the slope. It can also ensure the shielding and protection effect of the flat plate, forming a stable blocking surface when preventing smashing and shading, and adapting to the dual needs of airflow guidance and shielding and protection in multiple working modes.

[0041] Rotary motor 2: Rotary motor 2 is a servo rotary motor, and its output end is fixedly connected to the bottom surface of the front baffle 1 (that is, the bottom end of the plate). The core function of rotary motor 2 is to drive the front baffle 1 to rotate around its own rotation axis. Its rotation angle and rotation speed can be precisely controlled by the controller to meet the angle adjustment needs in multiple scenarios.

[0042] Meanwhile, the rotary motor 2 is slidably connected to the displacement guide rail 4, which is fixedly installed vertically inside the cockpit cover. Preferably, the outer side of the rotary motor 2's casing is provided with a sliding slider that matches the displacement guide rail 4. The slider is embedded in the groove of the displacement guide rail 4 and can move up and down linearly without jamming along the groove, thereby realizing the overall height adjustment of the rotary motor 2 and the front baffle 1.

[0043] Displacement motor 3: The displacement motor 3 is preferably a servo linear motor, which is fixedly installed inside the cab cover of the mining vehicle and arranged adjacent to the displacement guide rail 4. Its installation position is located on the top side of the displacement guide rail 4 to ensure that the power transmission stroke is compatible with the vertical length of the displacement guide rail 4. The displacement motor 3 provides power for the height adjustment of the rotary motor 2 and the front baffle 1. Its power output end is fixedly connected to one end of the transmission belt 5. By driving the rotation of the transmission belt 5, the rotary motor 2 is pulled to move up and down linearly along the displacement guide rail 4. Its traction displacement and traction speed can be precisely controlled by the controller to meet the accuracy requirements of height adjustment.

[0044] Displacement guide rail 4: The displacement guide rail 4 is preferably a rigid metal guide rail, which is fixedly installed vertically inside the cockpit cover. Its length is designed according to the internal vertical space of the cockpit cover and the height adjustment requirements of the front baffle 1. The bottom end of the displacement guide rail 4 is the first position limiting end of the rotary motor 2, and the top end is the second position limiting end of the rotary motor 2. It can physically limit the vertical movement of the rotary motor 2 to prevent component collision or structural damage caused by overtravel.

[0045] Transmission belt 5: Transmission belt 5 is a synchronous belt or chain drive structure. One end of it is fixedly connected to the power output end of displacement motor 3, and the other end is fixedly connected to the side wall of the housing of rotary motor 2. Transmission belt 5 must ensure that the power of displacement motor 3 is smoothly transmitted to rotary motor 2 in the vertical direction. Moreover, transmission belt 5 is only connected to the housing of rotary motor 2 and has no contact with the rotating shaft of rotary motor 2, so as to avoid the rotational motion of rotary motor 2 driving transmission belt 5 to rotate synchronously, so as to realize that the rotational motion of rotary motor 2 and the traction motion of displacement motor 3 are independent of each other and do not interfere with each other.

[0046] The main function of the transmission belt 5 is to transmit the linear displacement power of the displacement motor 3, convert the rotational power of the displacement motor 3 into the linear power to traction the rotary motor 2 to move up and down, and ensure the position control accuracy of the rotary motor 2 moving up and down along the displacement guide rail 4, as well as the accuracy of the height adjustment of the front baffle 1.

[0047] Controller: The controller is preferably an integrated control module, embedded in the center console of the mining vehicle's cab, but it can also be a separate device. It is electrically connected to the rotary motor 2 and the displacement motor 3, and can independently control the rotation of the rotary motor 2 and the traction action of the displacement motor 3, or control them to work together. The controller has a built-in torque calculation module, a vehicle resistance detection module, a signal receiving module, and a motion control module. Specifically: the torque calculation module calculates the motor's adaptation adjustment parameters based on the loading height of the minerals in the mining vehicle's cargo box; the vehicle resistance detection module acquires and determines the vehicle's aerodynamic resistance in real time; the signal receiving module receives various control and status signals; and the motion control module sends precise motion commands to the rotary motor 2 and the displacement motor 3 based on various signals and calculated parameters, enabling adaptive adjustment of the angle and height of the front baffle 1.

[0048] Meanwhile, the controller's signal receiving module can receive at least one input signal from the mobile terminal remote signal, the control button signal inside the cab, the control button signal outside the vehicle body, and the vehicle driving status signal, adapting to the control requirements under different operating scenarios. The control button inside the cab is located in an easily accessible position on the center console of the cab, the control button outside the vehicle body is located on the outside of the protective area at the front of the mining vehicle body, and the mobile terminal remote control is realized through wireless Bluetooth or IoT signals. All three can independently send control commands to the controller to realize the adjustment of the angle and height of the front baffle 1.

[0049] During the use of the mining vehicle turbulence protection system of this application:

[0050] When the rotary motor 2 moves vertically along the displacement guide rail 4, it has two core working positions, namely the first position and the second position. The two positions correspond to different rotation angles of the front baffle 1, and the specific coordination relationship is as follows:

[0051] First position: Rotary motor 2 is at the lower end of displacement guide rail 4. At this time, due to the structural space interference of the cab cover, the rotation space of the front baffle 1 is restricted. Rotary motor 2 drives the front baffle 1 to rotate around its rotation axis by 180°. This rotation angle can meet the basic scenario requirements such as sunshade, anti-smashing, and close-range rain protection during the normal operation of mining vehicles.

[0052] Second position: The displacement motor 3 pulls the rotary motor 2 along the displacement guide rail 4 to the top position via the transmission belt 5. At this time, the structural space rotation interference between the cab cover and the front baffle 1 is completely eliminated, and the rotation space of the front baffle 1 is fully released. The rotary motor 2 drives the front baffle 1 to expand its rotation angle around its rotation axis to 270°. This rotation angle can meet the advanced scenario requirements such as guiding the flow and preventing dust when the mining vehicle is traveling at high speed, as well as large-scale rain shelter during outdoor operations and dust suppression during unloading.

[0053] Implementation of multiple working modes for front baffle 1 (specific application scenarios):

[0054] The front baffle 1 is adjustable in angle via rotary motor 2 and in height via displacement motor 3, and can be switched to multiple working modes. The specific adjustment methods and working states of each mode are as follows:

[0055] (1) Traffic diversion mode:

[0056] When the mining truck is in motion and it is necessary to reduce the overall aerodynamic drag, this mode is the basic adaptation mode and is linked with the dust prevention mode. The controller uses the built-in vehicle drag detection module to obtain and judge the overall aerodynamic drag of the mining truck in real time. At the same time, the torque calculation module calculates the adaptation adjustment parameters based on the loading height of the minerals in the cargo box of the mining truck. Then, based on the calculated parameters, it adaptively controls the rotation angle of the rotary motor 2 and the displacement distance of the displacement motor 3 to adjust the front baffle 1 to the position with the lowest wind resistance of the vehicle. At this time, the displacement motor 3 pulls the rotary motor 2 to move upward along the displacement guide rail 4 to the second position. The inclined slope and arc surface of the front baffle 1 face the front of the mining truck. The oncoming airflow is smoothly guided upward along the inclined slope and arc surface, effectively sorting the airflow, reducing the overall aerodynamic drag of the vehicle, and improving the driving stability and fuel economy of the mining truck.

[0057] If the mineral loading height inside the cargo box is low, the controller will coordinate with the fine-tuning of the rotation angle of the rotary motor 2 and the traction height of the displacement motor 3 to ensure that the front baffle 1 always maintains the optimal wind resistance angle that matches the mineral height, taking into account both the airflow guiding effect and the dust prevention requirements.

[0058] (2) Dust prevention mode

[0059] This mode works in tandem with the flow control mode, and is divided into two states: dust prevention during driving and dust prevention during unloading. It adapts and adjusts based on the angle and height of the baffles in the flow control mode.

[0060] Dust prevention during driving: During the driving of the mining vehicle, based on the position of the baffle in the flow guiding mode, the inclined slope and arc surface of the front baffle 1 will guide the oncoming airflow upward, thereby preventing the airflow from directly impacting the minerals in the cargo box, effectively preventing the minerals from being blown up by the wind and forming dust, reducing dust pollution in the mining area and improving the quality of the working environment.

[0061] Dust control during unloading: When the mining truck is unloading minerals, the controller adjusts the rotation angle of the rotary motor 2 and the traction displacement of the displacement motor 3 in real time according to the unloading tilt angle of the cargo box and the unloading speed of the minerals. This ensures that the inclined slope of the front baffle 1 is precisely adapted to the airflow direction during the unloading process, forming a physical barrier and directional guide for the dust raised during unloading, inhibiting the dust from rising and spreading, preventing dust from entering the driver's field of vision and affecting operation, and at the same time protecting the respiratory health of the mining site workers.

[0062] (3) Shading mode

[0063] When miners take a break during work or the mining vehicle is parked and sun protection is needed for the cab, the controller controls the displacement motor 3 to pull the rotary motor 2 down along the displacement guide rail 4 to the first position via the transmission belt 5. Simultaneously, the controller controls the rotary motor 2 to drive the front baffle 1 to rotate around its axis to a suitable sun-shading angle, so that the flat surface of the front baffle 1 faces the front and upper side of the cab, completely blocking direct sunlight and effectively reducing the light intensity inside the cab. This provides privacy for the personnel inside the cab. The shading angle can be precisely adjusted by the controller according to the real-time direction of sunlight. This mode is also suitable for preventing impact damage.

[0064] (4) Rain Shelter Mode

[0065] When a mining vehicle is operating outdoors and encounters sudden rainfall requiring rain protection for the cab, the controller, based on the rainfall area and real-time direction, controls the rotary motor 2 to drive the front baffle 1 to rotate around its axis to a tilted rain-shielding position. Simultaneously, according to the cab's rain protection needs, the controller controls the displacement motor 3 to pull the rotary motor 2 to make slight height adjustments at the first or second position of the displacement guide rail 4, so that the front baffle 1 forms a fitted rain shelter structure at the front of the cab. At this time, the inclined slope of the front baffle 1 faces the direction of rainfall, allowing rainwater to slide smoothly down the slope, preventing rainwater from directly entering the cab. The rain-shielding range can be precisely controlled through coordinated fine-tuning of the baffle's angle and height, adapting to rain protection needs of different rainfall intensities and directions.

[0066] The overall workflow of the system is as follows:

[0067] (1) After the mining vehicle starts, the controller automatically completes the system initialization, the vehicle resistance detection module and torque calculation module start synchronously, and the rotary motor 2 and displacement motor 3 are in the initial standby state;

[0068] (2) The controller sends action commands to the rotary motor 2 and the displacement motor 3 according to the mining vehicle operation instructions or driving status. The displacement motor 3 pulls the rotary motor 2 to move along the displacement guide rail 4 between the first position and the second position through the transmission belt 5. At the same time, the rotary motor 2 drives the front baffle 1 to rotate around its rotation axis to the appropriate angle, thus completing the precise adjustment of the height and angle of the front baffle 1.

[0069] (3) After the front baffle 1 is adjusted to the target position, the rotary motor 2 and the displacement motor 3 are locked, and the system maintains the corresponding working mode to meet the operational needs of mining vehicles for diversion, dust prevention, impact prevention, sunshade and rain protection.

[0070] (4) When the mining vehicle's operating scene changes, the controller receives the input signal again and calculates the adaptation parameters, repeating the above height and angle adjustment actions to achieve rapid switching of the working mode;

[0071] (5) After the mining vehicle finishes its work and shuts off, the controller automatically sends a reset command to control the rotary motor 2 to drive the front baffle 1 to rotate to the initial angle. The displacement motor 3 pulls the rotary motor 2 down along the displacement guide rail 4 to the first position and locks it. The system completes the overall reset and waits for the next operation to start.

[0072] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
