Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to a top airflow control system, a fairing, and a tractor. Background Technology

[0002] A tractor unit is a type of heavy-duty vehicle. Tractor units typically have a roof-mounted fairing, which improves aerodynamics and reduces air resistance, thereby enhancing overall performance such as fuel efficiency and driving stability, while also improving the vehicle's overall appearance. Although roof fairings offer significant advantages in improving aerodynamics, they still have some drawbacks and functional limitations. For example, existing tractor unit fairings are usually fixed to the roof and cannot be dynamically adjusted according to real-time driving conditions. This means that under certain operating conditions, a fixed angle of attack may not provide optimal aerodynamic performance. Secondly, existing roof fairings are also too limited in function, lacking development of other functionalities. Summary of the Invention

[0003] This invention provides a top airflow control system, a fairing, and a tractor vehicle to solve the shortcomings of existing technologies where the top airflow fairing structure is fixed, cannot be dynamically adjusted according to real-time driving conditions, and has overly limited functionality.

[0004] The present invention provides a top airflow control system, including a wind speed identification mechanism and a control unit.

[0005] Wind speed identification mechanism, suitable for installation on top guide bracket assembly.

[0006] The control unit can drive the top guide bracket assembly to adjust its elevation angle based on wind speed data.

[0007] The wind speed recognition mechanism can acquire wind energy and wind speed data during vehicle operation, and drive the movement of charges through the wind energy to convert the wind energy into electrical energy to supply the control unit and the top guide bracket assembly.

[0011] The wind speed recognition sensor rotation mechanism can contact the electrode plate through rotation and cause charge flow, thereby recognizing the wind speed data and converting wind energy into electrical energy.

[0012] According to a top airflow control system provided by the present invention, the wind speed identification sensor rotation mechanism includes a rotating shaft and several blades.

[0013] A rotating shaft is mounted on the base.

[0014] Several blades are fixed to the outside of the rotating shaft at intervals, and the protruding end of each blade is connected to a nanofilm; under the rotation of the rotating shaft, the nanofilm of each blade contacts the electrode plate in sequence.

[0015] According to a top flow control system provided by the present invention, the base includes a base plate and a pair of upright plates.

[0016] The base plate is fixed to the top guide bracket assembly.

[0017] A pair of upright plates are vertically connected to both sides of the base plate, and a channel for airflow is left between the pair of upright plates. The electrode plate is laid on the surface of the base plate at one end of the channel.

[0018] The two ends of the rotating shaft are respectively connected to a pair of vertical plates, and the rotating shaft is placed horizontally above the electrode plate.

[0019] According to the present invention, a top flow control system is provided, wherein the nanofilm is made of FEP nanomaterial and the electrode plate is a copper plate.

[0020] According to a top flow control system provided by the present invention, the protruding end of the blade has a curved arc relative to the fixed end, and the bending direction of the blade is opposite to the rotation direction of the rotating shaft.

[0021] According to the top airflow control system provided by the present invention, the working states of the wind speed identification mechanism include an initial state, a pre-charging state, and a power generation induction state.

[0022] The wind speed identification mechanism in the initial state can identify that there is no external wind energy and that the wind speed identification mechanism is in a stationary state.

[0023] The wind speed identification mechanism in the pre-charge state can identify the presence of external wind energy, and the wind speed identification mechanism drives the charge to transfer continuously, converting the wind energy into electrical energy.

[0024] The wind speed identification mechanism in the power generation induction state can identify the presence of external wind energy and drive the charge to transfer periodically, thereby acquiring the wind speed data and generating electricity.

[0025] The present invention also provides a flow guide, including a top flow guide plate, a top flow guide support assembly, and a top flow guide control system as described above.

[0026] Top air deflector, suitable for installation on the vehicle roof.

[0027] The top guide bracket assembly connects to and supports the top guide plate.

[0028] The wind speed identification mechanism of the top airflow control system is installed on the top airflow support assembly.

[0029] According to a flow guide provided by the present invention, the top flow guide support assembly includes at least a pair of flip hinges, a main crossbeam, at least a pair of telescopic mechanisms, and an auxiliary support.

[0030] At least one pair of flip hinges are connected between the top air deflector and the roof, and the wind speed recognition mechanism is disposed between adjacent flip hinges.

[0031] The main crossbeam is placed horizontally on the lower surface of the top guide plate and is located on the end of the top guide plate away from the flip hinge.

[0032] At least one pair of telescopic mechanisms, each telescopic mechanism having one end connected to the main crossbeam and the other end connected to the roof.

[0033] An auxiliary support is connected to one side of the main crossbeam, and the control unit of the top flow control system is fixed between the auxiliary support and the top flow plate.

[0034] The present invention also provides a tractor vehicle equipped with the top airflow control system as described above; or equipped with the airflow shield as described above.

[0035] The top airflow control system provided by this invention includes a wind speed recognition mechanism and a control unit. The wind speed recognition mechanism is suitable for installation on the top airflow support assembly; the control unit can drive the top airflow support assembly to adjust its elevation angle based on wind speed data; the wind speed recognition mechanism can acquire wind energy and wind speed data during vehicle operation, and drive the movement of charges through wind energy, thereby converting wind energy into electrical energy to supply the control unit and the top airflow support assembly. By installing this top airflow control system, on the one hand, the fairing can acquire and monitor wind speed data during vehicle operation in real time using the wind speed recognition mechanism, thereby flexibly adjusting the elevation angle of the top airflow support assembly according to wind speed changes, and thus adjusting the attitude of the fairing to reduce wind resistance of the tractor during driving; on the other hand, the wind speed recognition mechanism can convert wind energy into electrical energy, thereby acting as a generator to provide power support for the other components of the top airflow control system.

[0036] Therefore, this top airflow control system, through the wind speed recognition mechanism, can monitor the external environment in real time and measure the wind speed during vehicle operation. Furthermore, this wind speed recognition mechanism can transmit the real-time wind speed data to the control unit, which then analyzes and processes the wind speed information. Based on the wind speed changes, the control unit drives the top airflow bracket assembly to adjust its elevation angle, thus achieving stepless adjustment of the top airflow vane's elevation angle without manual assistance. In other words, this top airflow control system can optimize the vehicle's aerodynamic performance according to surrounding conditions, thereby providing more efficient, convenient, and accurate top airflow guidance for moving vehicles and reducing air resistance.

[0037] Based on this, the top airflow control system can also independently achieve self-powered and self-adjusting functions through the wind speed recognition mechanism. It does not need to cooperate with other parts of the vehicle, nor does it need to be connected to the vehicle's main power system. In other words, the top airflow control system is both independent and compatible with the vehicle's power system, which is very convenient for subsequent maintenance and repair.

[0038] The present invention also provides a fairing, including a top deflector, a top deflector support assembly, and a top deflector control system as described above. The top deflector is suitable for installation on the vehicle roof; the top deflector support assembly connects to and supports the top deflector; the wind speed recognition mechanism of the top deflector control system is mounted on the top deflector support assembly. By setting the above-described top deflector control system, the fairing possesses all the advantages of the aforementioned top deflector control system, which will not be elaborated further here.

By setting the top airflow control system or the air deflector described above, the tractor unit possesses all the advantages of the top airflow control system described above, which will not be elaborated further here.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0054] The following is combined Figures 1-16 The invention describes a top flow control system (hereinafter referred to as the "flow control system"), a flow control cover and a tractor vehicle on which the flow control system is installed.

[0055] like Figure 1 As shown, the top airflow control system provided by this invention includes a wind speed recognition mechanism 200 and a control unit. The wind speed recognition mechanism 200 is adapted to be installed on the top airflow support assembly 300 and can acquire wind energy and wind speed data during vehicle operation. On one hand, the wind speed recognition mechanism 200 can acquire wind speed data during vehicle operation in real time and input the wind speed information into the control unit; that is, the wind speed recognition mechanism 200 can act as a wind speed sensor to transmit real-time data to the control unit. The control unit can drive the top airflow support assembly 300 to adjust the elevation angle based on the wind speed data, thereby adjusting the top structure of the airflow fairing to the optimal elevation angle control value to reduce wind resistance of the tractor during operation. On the other hand, the wind speed identification mechanism 200 has a mechanism that can generate its own electricity. It can drive the movement of charges between its internal components through wind energy, thereby converting wind energy into mechanical energy and then into electrical energy. Finally, it converts wind energy into electrical energy and supplies it to the control unit and the top guide bracket assembly 300. This allows the wind speed identification mechanism 200 to act as a generator to provide power support to the entire guide system, thus achieving the independence of the guide system.

[0056] like Figure 2 and Figure 3 As shown, the fairing of this embodiment includes a top guide plate 100, a top guide bracket assembly 300, and the top guide control system described above. The top guide plate 100 is adapted to be mounted on the roof and connected to and supported by the top guide bracket assembly 300, thereby achieving support for the top guide plate 100 and adjustment of its elevation angle. The wind speed recognition mechanism 200 of the guide system is mounted on the top guide bracket assembly 300. By setting the above-described top guide control system, the fairing possesses all the advantages of the aforementioned top guide control system, which will not be elaborated further here.

[0057] In some embodiments, the top deflector 100 is preferably configured based on the roof structure as follows: Figure 2 and Figure 3 The shape shown is characterized by a main body that covers part of the roof along the vehicle's width, with secondary bodies connected to both sides of the main body. These secondary bodies are bent in the same direction relative to the main body, forming a support structure with an approximately triangular cross-section. A top airflow guide assembly 300 is connected to the roof-facing surface of the main body and to the roof itself. A wind speed recognition mechanism 200 is connected at the point where the main body connects to the roof, enabling accurate monitoring and measurement of wind speed data and real-time environmental information at the roof location.

[0058] In some embodiments, such as Figure 3As shown, the top air deflector assembly 300 includes at least one pair of flip hinges 303, a main crossbeam 301, at least one pair of telescopic mechanisms 302, and an auxiliary support 304. Each flip hinge 303 connects the top air deflector 100 to the vehicle roof, enabling the top air deflector 100 to rotate and rise relative to the vehicle roof. A wind speed recognition mechanism 200 is positioned between adjacent flip hinges 303, capable of recognizing wind speed data and real-time environmental information at the vehicle roof location. The main crossbeam 301 is horizontally positioned on the lower surface of the top air deflector 100, i.e., the surface of the top air deflector 100 facing the vehicle roof. This main crossbeam 301 is located at the end of the top air deflector 100 furthest from the flip hinges 303, providing overall support and attitude control for the top air deflector 100. Each telescopic mechanism 302 has one end connected to the main crossbeam 301 and the other end connected to the roof. Telescopic movement of the main crossbeam 301 drives the top deflector 100 to rotate and rise relative to the roof, thus adjusting the elevation angle between the top deflector 100 and the roof. An auxiliary bracket 304 is connected to one side of the main crossbeam 301, and the control unit of the deflector system is fixed between the auxiliary bracket 304 and the top deflector 100. Preferably, the auxiliary bracket 304 is V-shaped, with the main crossbeam 301 fixed to both ends of the auxiliary bracket 304, and the control unit fixed between the auxiliary bracket 304 and the top deflector 100, thereby using the auxiliary bracket 304 to position and support the control unit.

[0059] It should be noted that, in order to improve the structural strength of the top guide plate 100 and facilitate the adjustment of the attitude and elevation angle of the top guide plate 100, it is preferable that the lower surface of the top guide plate 100 is also equipped with several support frames arranged in a truss structure.

[0060] like Figure 4 , Figure 5 and Figure 6 As shown, the wind speed identification mechanism 200 of this embodiment includes a base 201 and a wind speed identification sensor rotation mechanism 203. The base 201 is fixedly mounted on the top guide bracket assembly 300, as shown... Figure 2 As shown, an electrode plate 207 is provided on the base 201. A wind speed identification sensor rotation mechanism 203 is rotatably connected to the base 201 and located above the electrode plate 207. The wind speed identification sensor rotation mechanism 203, through rotation, contacts the electrode plate 207 and induces charge flow, enabling electrons to move between the electrode plate 207 and the wind speed identification sensor rotation mechanism 203. This electron transfer forms a current, allowing the wind speed identification sensor rotation mechanism 203 to accurately reflect changes in external excitation (wind force and wind speed) through periodic charge transfer, thereby identifying wind speed data. Furthermore, the formation of this current causes the wind speed identification sensor rotation mechanism 203 to move in conjunction with the electrode plate 207, converting wind energy into electrical energy.

[0061] In some specific embodiments, such as Figure 4, Figure 5 and Figure 6 As shown, the wind speed recognition sensor rotation mechanism 203 includes a rotating shaft and several blades 211. The rotating shaft is mounted on the base 201. Several blades 211 are fixedly connected to the outside of the rotating shaft at intervals. Each blade 211 has a nanofilm 206 connected to its protruding end. Under the rotation of the rotating shaft, the nanofilm 206 of each blade 211 sequentially contacts the electrode plate 207. Because the blades 211 are arranged at intervals outside the rotating shaft, and as... Figure 6 As shown, after the nanofilm 206 on each blade 211 of the wind speed sensor rotation mechanism 203 has fully contacted the electrode plate 207 and completed pre-charging, the periodic and intermittent contact with the electrode plate 207 ensures that electrons on the electrode plate 207 are periodically transferred to the nanofilm 206 on the blade 211, thereby forming a current. Moreover, this periodic contact process can also cause a change in the direction of current movement. Therefore, as the wind speed sensor rotation mechanism 203 continues to rotate, the nanofilm 206 on the blade 211 periodically contacts the electrode plate 207, thereby causing periodic charge transfer between the nanofilm 206 and the electrode plate 207, and further causing periodic charge transfer between the electrode plate 207 and the ground.

[0062] In some specific embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the base 201 includes a base plate and a pair of upright plates. The base plate is fixed to the top guide bracket assembly 300, ensuring reliable fixation between the base 201 and the top guide bracket assembly 300. Preferably, the bottom of the base plate is covered with a rubber base 202 for fixation and anti-slip purposes. The pair of upright plates are vertically connected to both sides of the base plate, and a channel for airflow is left between the pair of upright plates. This channel is essentially enclosed by the base plate and the pair of upright plates, and the top of the channel is open; alternatively, a separate top plate can be designed to close the channel.

[0063] In some specific embodiments, such as Figure 6 As shown, an electrode plate 207 is installed on the surface of the base plate at one end of the channel. The two ends of the aforementioned rotating shaft are respectively connected to a pair of upright plates, and the rotating shaft is positioned horizontally above the electrode plate 207. This structural arrangement allows the wind speed recognition sensor rotating mechanism 203 and the electrode plate 207 to be installed at the same end of the channel. This enables the channel to guide airflow and allows for more accurate and reliable visual recognition of wind speed data. Furthermore, it ensures that the blades 211 and the electrode plate 207 make accurate contact, achieving charge transfer and resulting in efficient power generation.

[0064] It should be noted that, preferably, the nanofilm 206 is made of FEP nanomaterial, and preferably, the electrode plate 207 is a copper plate. Because the FEP nanofilm 206 and the copper electrode plate 207 have different electron affinities, they are two highly different positive and negative friction materials in the triboelectric series. This allows for reliable contact and friction between the nanofilm 206 and the electrode plate 207 through rotation, thereby generating electricity by transferring electrons. The materials of the nanofilm 206 and the electrode plate 207 are not limited to FEP nanofilm 206 and copper electrode; any combination of two highly different positive and negative friction materials from the triboelectric series can be used, as long as the friction between the nanofilm 206 and the electrode plate 207 can induce electron transfer and generate electricity. Preferably, the surface of the FEP film can be microstructured to further improve the contact area between the FEP nanofilm and the copper electrode.

[0065] It should be noted that, preferably, the protruding end of the blade 211 has a curved arc relative to the fixed end, and the bending direction of the blade 211 is opposite to the rotation direction of the rotating shaft. This structural arrangement allows the protruding end of the blade 211 to periodically form partial surface contact with the electrode plate 207, which can increase the contact area and improve charging and power generation efficiency.

[0066] It should be noted that the blade 211 is connected to the rotating shaft and located between a pair of upright plates. Preferably, the long side of the blade 211 is connected to the outer surface of the rotating shaft along the axial direction of the rotating shaft, and the width direction of the blade 211 extends outward to form the blade 211 structure. The nanofilm 206 is connected to the extended end of the blade 211 by several fasteners 208. Preferably, the fasteners 208 are screws. This structural arrangement ensures that the airflow flows through the channel and can more evenly contact each rotating blade 211, increasing the contact area, thereby improving charging and power generation efficiency, and also increasing the accuracy and timeliness of wind speed identification.

[0067] It should be noted that the preferred rotating shaft includes a bushing 204 and a core 205. The bushing 204 is fitted over the core 205. The bushing 204 is constructed as a cylindrical barrel structure, with several outwardly extending fins evenly distributed on its exterior. The ends of the fins are connected to the aforementioned nanofilm 206, thereby forming several blades 211 on the exterior of the bushing 204. Preferably, the core 205 of the rotating shaft has threaded holes at both ends, and a pair of through holes are provided on a pair of upright plates of the base 201 to determine the position for mounting the rotating shaft. The pair of through holes are coaxially arranged to ensure that the axis of the rotating shaft is perpendicular to the length direction of the channel of the base 201. A locking nut 210 is passed through one of the upright plates and tightened into the threaded hole at the end of the core 205, thereby ensuring that when the airflow passes through the wind speed identification sensor rotating mechanism 203, the bushing 204 of the rotating shaft rotates around the core 205 under the influence of the airflow, while the core 205 remains stationary due to the fixing effect of the locking nut 210. To improve the reliability of the connection between the locking nut 210 and the upright plate and increase friction, it is preferable to add a washer 209 between the locking nut 210 and the upright plate.

[0068] It should be noted that the base plate of the preferred base 201 and the base 202 are coaxially connected by a mounting hole 212. The base 201 of the wind speed recognition mechanism 200 can be connected to the roof of the vehicle by means of a connecting structure passing through the mounting hole 212, such as bolts.

[0069] The following is for reference Figures 7 to 16 Describe in detail the specific working status of the wind speed identification mechanism 200.

[0070] In this embodiment of the invention, the working state of the wind speed identification mechanism 200 includes the initial state (refer to...). Figure 7 As shown), pre-charge state (reference) Figures 8 to 10 (as shown) and power generation induction status (reference) Figures 11 to 15 (As shown).

[0071] When the wind speed identification mechanism 200 is in a stationary initial state without external wind excitation, it can identify that there is no external wind energy and that it is stationary. In this state, if... Figure 7 As shown, the nanofilm 206 of the wind speed recognition mechanism 200 is located above the electrode plate 207, and the two do not contact each other, so no charge transfer will occur at this time.

[0072] When an external wind force drives the wind speed identification mechanism 200 to rotate, the wind speed identification mechanism 200 enters the working state and goes through the pre-charging state and the power generation induction state respectively.

[0073] The wind speed recognition mechanism 200 is in a pre-charging state, such as Figure 8As shown, the wind speed recognition sensor rotating mechanism 203 begins to rotate under the drive of external wind power. The attached nanofilm 206 comes into contact with and rubs against the electrode plate 207. Therefore, when these two positive and negative friction materials with large differences come into contact, such as... Figure 8 and Figure 9 As shown, the surfaces of the electrode plate 207 and the nanofilm 206 are respectively positively charged and negatively charged. Since the nanofilm 206 in this embodiment of the invention is made of FEP nanomaterial, and FEP nanomaterial is a substrate material, even if... Figure 10 After being separated from the copper electrode plate 207, the triboelectric charge attached to the nanofilm 206 does not easily disappear, and the negative charge characteristic can be retained for a long time. Therefore, the wind speed recognition mechanism 200 in the pre-charged state can recognize the presence of external wind energy, and the wind speed recognition mechanism 200 drives continuous charge transfer, converting wind energy into electrical energy.

[0074] After the nanofilm 206 undergoes the aforementioned pre-charge state, it reaches a state of negative charge saturation and remains relatively stationary and non-contact with the electrode plate 207. Figure 11 As shown, at this time, the electrode plate 207 and the connected ground electrode maintain electrostatic equilibrium, with no charge transfer. When the wind continues to provide external excitation, the negatively charged nanofilm 206 comes into contact with the electrode plate 207, breaking this potential equilibrium. To balance the potential difference, electrons in the external circuit flow from the electrode plate 207 to the ground electrode, thereby causing the external circuit to output an electrical signal, i.e., as shown... Figure 12 As shown; until the nanofilm 206 is in full contact with the electrode plate 207, electron transfer reaches its maximum, i.e., as shown. Figure 13 As shown, when the wind speed recognition sensor rotating mechanism 203 continues to rotate, the nanofilm 206 begins to separate from the electrode plate 207, i.e. Figure 14 As shown, electrons flow from the ground electrode to the copper electrode, changing the direction of the current; until the nanofilm 206 and the electrode plate 207 are in a relatively stationary and non-contact state, that is, as Figure 15 As shown. Therefore, with the continuous rotation of the wind speed recognition sensor rotation mechanism 203, each nanofilm 206 intermittently undergoes the aforementioned process with the electrode plate 207, thereby causing periodic charge transfer between the electrode plate 207 and the ground electrode. Thus, the electrical signal output of the wind speed recognition mechanism 200 can accurately reflect changes in external excitation, i.e., wind speed changes, thereby acquiring real-time wind speed data. During this process, the external circuit connected to the ground electrode outputs an electrical signal to generate electricity. Therefore, the wind speed recognition mechanism 200, in a power generation induction state, can identify the presence of external wind energy and drive periodic charge transfer, thereby acquiring wind speed data and generating electricity.

[0075] It should be noted that, as Figure 16As shown, the higher the wind speed, the more voltage pulses there will be per unit time, and the higher the voltage value will be.

[0076] Therefore, compared with the prior art, the top airflow control system and the airflow shield equipped with the airflow system described in this embodiment of the invention not only identify and detect environmental data such as wind speed and vehicle speed, but also, through the connection structure between the airflow shield and the airflow system, better reduce turbulence and rear drag during vehicle operation. Furthermore, the structure of the top airflow support assembly 300 of the airflow shield allows for multi-dimensional adjustment of parameters such as the elevation angle and opening height of the top airflow plate 100, and the control unit organically combines elevation angle control and environmental information to achieve more precise control. Moreover, this airflow system has more diversified functions than the prior art, making full use of surrounding environmental resources. It utilizes the wind speed identification mechanism 200 as a generator to achieve self-generation of the airflow system, giving it independent power generation capability relative to the vehicle's electrical system, thus ensuring its independence.

[0077] The tractor provided in this embodiment of the invention is equipped with the top airflow control system as described above; or with the airflow deflector as described above. By setting the top airflow control system or the airflow deflector as described above, the tractor possesses all the advantages of the top airflow control system described above, which will not be elaborated further here.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
