Description

Technical Field

[0001] The invention relates to the technical field of automobiles, and in particular to a top air guide control system, an air guide cover and a tractor. Background Art

[0002] A tractor is a heavy-duty vehicle. A tractor is usually equipped with a top fairing on the roof, which can reduce air resistance by improving aerodynamic performance, thereby improving overall performance such as fuel efficiency and driving stability, while also improving the overall appearance of the vehicle. Although the top fairing has significant advantages in improving aerodynamic performance, there are still some disadvantages and functional limitations. For example, the top fairing of existing tractors is usually fixed to the roof and cannot be dynamically adjusted according to real-time driving conditions. This means that under certain specific working conditions, a fixed elevation angle may not provide the best aerodynamic effect. Secondly, the existing top fairing is too single in function and has not been developed for other functions. Summary of the invention

[0007] The wind speed identification mechanism can obtain wind energy and the wind speed data during the operation of the vehicle, and drive the movement of electric charges through the wind energy, thereby converting the wind energy into electrical energy and supplying it to the control unit and the top guide bracket assembly.

[0008] According to a top airflow control system provided by the present invention, the wind speed identification mechanism includes a base and a wind speed identification sensor rotating mechanism.

[0009] The base is fixedly mounted on the top guide bracket assembly, and an electrode plate is arranged on the base.

[0010] The wind speed identification sensor rotating mechanism is rotatably connected to the base and is located above the electrode plate.

[0011] The wind speed identification sensor rotating mechanism contacts the electrode plate through rotation energy and causes charge flow, thereby identifying the wind speed data and converting wind energy into electrical energy.

[0012] According to a top flow guide control system provided by the present invention, the wind speed identification sensor rotating mechanism includes a rotating shaft and a plurality of blades.

[0013] The rotating shaft is installed on the base.

[0014] A plurality of blades are fixedly connected to the outside of the rotating shaft at intervals, and the extended end of each blade is connected with a nano film; under the rotation of the rotating shaft, the nano film of each blade contacts the electrode plate in turn.

[0016] The bottom plate is fixedly connected to the top guide bracket assembly.

[0017] A pair of vertical plates are vertically connected to both sides of the bottom plate, and a channel for airflow to pass through is reserved between the pair of vertical plates, and the surface of the bottom plate at one end of the channel is paved with the electrode plate.

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

[0019] According to a top flow control system provided by the present invention, the nano-membrane is made of FEP nano-material, and the electrode plate is a copper plate.

[0020] According to a top flow guide and control system provided by the present invention, the extended end of the blade has a bending curvature 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 a top flow diversion 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 the wind speed identification mechanism is in a stationary state.

[0023] The wind speed recognition mechanism in the pre-charging state can recognize the presence of external wind energy, and the wind speed recognition mechanism drives the charge to be continuously transferred to convert the wind energy into the 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 periodic transfer of the charge, thereby acquiring the wind speed data and generating electricity.

[0025] The present invention also provides a deflector cover, comprising a top deflector plate, a top deflector bracket assembly and the top deflection regulating system as described above.

[0026] A top deflector is suitable for installation on a vehicle roof.

[0027] The top guide bracket assembly is used to connect and support the top guide plate.

[0028] The wind speed identification mechanism of the top air guide control system is installed on the top air guide bracket assembly.

[0029] According to a deflector provided by the present invention, the top deflector bracket assembly includes at least one pair of flip hinges, a main cross beam, at least one pair of telescopic mechanisms and an auxiliary bracket.

[0030] At least one pair of flip hinges is connected between the top deflector and the vehicle roof, and the wind speed identification mechanism is arranged between adjacent flip hinges.

[0031] The main cross beam is disposed transversely on the lower surface of the top guide plate and is located at the end of the top guide plate away from the flip hinge.

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

[0033] An auxiliary bracket is connected to one side of the main crossbeam, and a control unit of the top air guide regulating system is fixed between the auxiliary bracket and the top air guide plate.

[0034] The present invention also provides a tractor equipped with the top air flow control system as described above; or equipped with the air flow deflector as described above.

[0035] The top flow guide control system provided by the present invention includes a wind speed identification mechanism and a control unit. The wind speed identification mechanism is suitable for being installed on the top flow guide bracket assembly; the control unit can drive the top flow guide bracket assembly to adjust the elevation angle based on the wind speed data; the wind speed identification mechanism can obtain the wind energy and wind speed data during the operation of the vehicle, and drive the movement of electric charges through wind energy, so as to realize the conversion of wind energy into electrical energy and supply it to the control unit and the top flow guide bracket assembly. By installing the top flow guide control system, on the one hand, the deflector can use the wind speed identification mechanism to obtain and monitor the wind speed data during the operation of the vehicle in real time, so as to flexibly adjust the elevation angle of the top flow guide bracket assembly according to the change of wind speed, and then adjust the posture of the deflector to reduce the wind resistance of the tractor during driving; on the other hand, the wind speed identification mechanism can convert wind energy into electrical energy, so as to act as a generator to provide power support for the remaining components of the top flow guide control system.

[0036] It can be seen that the top air guide control system can monitor the external environment in real time and measure the wind speed of the vehicle in real time by setting up a wind speed identification mechanism. In addition, the wind speed identification mechanism can transmit the wind speed data in the external environment obtained in real time to the control unit, so that the control unit can analyze and process the wind speed information, and drive the top air guide bracket assembly to adjust the elevation angle according to the wind speed change, so as to achieve stepless adjustment of the elevation angle of the top air guide plate of the air guide cover without manual assistance; that is, the top air guide control system can optimize the aerodynamic performance of the vehicle according to the surrounding working conditions, so as to more efficiently, conveniently and accurately guide the top of the moving vehicle and reduce air resistance.

[0037] On this basis, the top air diversion and control system can independently realize the functions of self-power supply and self-regulation through the wind speed identification mechanism, without the need to cooperate with the other components of the vehicle, and without the need to carry the vehicle's main power system. That is, the top air diversion and control system is both independent and compatible with the vehicle's power system, which is very convenient for subsequent maintenance and repair.

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Combine the following Figure 1-Figure 16 The top flow guiding and regulating system of the present invention (hereinafter referred to as “flow guiding system” for short) and the flow guiding cover and tractor equipped with the flow guiding system are described.

[0054] like Figure 1 As shown, the top air guide control system provided by the present invention includes a wind speed identification mechanism 200 and a control unit. The wind speed identification mechanism 200 is suitable for being installed on the top air guide bracket assembly 300, and can obtain wind energy and wind speed data during the operation of the vehicle. On the one hand, the wind speed identification mechanism 200 can obtain the wind speed data during the operation of the vehicle in real time, and input the wind speed information into the control unit, that is, the wind speed identification mechanism 200 can transmit real-time data to the control unit as a wind speed sensor; and the control unit can drive the top air guide bracket assembly 300 to adjust the elevation angle based on the wind speed data, so that the top structure of the air guide cover is adjusted to the optimal elevation angle control amount, so as to reduce the wind resistance of the tractor during driving. On the other hand, the wind speed identification mechanism 200 has a mechanism that can realize self-generation, and can use wind energy to drive the movement of electric charges between its internal components, thereby realizing the conversion of wind energy into mechanical energy and then into electrical energy, and finally realizing the conversion of wind energy into electrical energy and supplying it to the control unit and the top guide bracket assembly 300, so that the wind speed identification mechanism 200 can act as a generator to provide power support to the entire guide system, thereby realizing the independence of the guide system.

[0055] like Figure 2 and Figure 3 As shown, the deflector described in the embodiment of the present invention includes a top deflector plate 100, a top deflector bracket assembly 300 and the top deflector control system as described above. The top deflector plate 100 is suitable for being installed on the roof of the vehicle. The top deflector bracket assembly 300 connects and supports the top deflector plate 100, so as to achieve support for the top deflector plate 100 and adjustment of the elevation angle. The wind speed identification mechanism 200 of the deflection system is installed on the top deflector bracket assembly 300. By setting the above-mentioned top deflector control system, the deflector has all the advantages of the above-mentioned top deflector control system, and the details will not be repeated here.

[0056] In some embodiments, the top deflector 100 is preferably configured as follows based on the structure of the roof. Figure 2 and Figure 3 The shape shown is a main body that covers part of the roof along the width direction of the vehicle, and two sub-plates are connected to the two sides of the main body, and the pair of sub-plates are bent in the same direction relative to the main body, so that the sub-plate and the main body form a support structure with a cross section that is approximately triangular. The top guide bracket assembly 300 is connected to the surface of the main body facing the roof and connected to the roof, and the wind speed identification mechanism 200 is connected to the main body and the roof, so as to accurately monitor and measure the wind speed data and real-time environmental information at the roof position.

[0057] In some embodiments, Figure 3As shown, the top deflector bracket 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 bracket 304. Each flip hinge 303 is connected between the top deflector 100 and the roof, and is used to realize the rotation and lifting of the top deflector 100 relative to the roof. The wind speed identification mechanism 200 is arranged between adjacent flip hinges 303, and can identify the wind speed data and real-time environmental information at the roof position. The main crossbeam 301 is placed horizontally on the lower surface of the top deflector 100, that is, the surface of the top deflector 100 facing the roof. The main crossbeam 301 is located on the end of the top deflector 100 away from the flip hinge 303, and plays a role in overall support and posture control of the top deflector 100. One end of each telescopic mechanism 302 is connected to the main crossbeam 301, and the other end is connected to the roof. The main crossbeam 301 is driven to move by telescopic movement, and then the top deflector 100 is driven to rotate and rise relative to the roof, so as to adjust the elevation angle of the top deflector 100 and the roof. The auxiliary bracket 304 is connected to one side of the main crossbeam 301, and the control unit of the deflection system is fixed between the auxiliary bracket 304 and the top deflector 100. Preferably, the auxiliary bracket 304 is arranged in a V shape, and the two ends of the auxiliary bracket 304 are respectively fixed to the main crossbeam 301, and the control unit is fixed between the auxiliary bracket 304 and the top deflector 100, so that the auxiliary bracket 304 is used to position and support the control unit.

[0058] It should be noted that, in order to improve the structural strength of the top guide plate 100 and facilitate adjustment of the posture and elevation angle of the top guide plate 100 , it is preferred that a plurality of support frames arranged in a truss structure are also installed on the lower surface of the top guide plate 100 .

[0059] like Figure 4 , Figure 5 and Figure 6 As shown, the wind speed identification mechanism 200 described in the embodiment of the present invention includes a base 201 and a wind speed identification sensor rotating mechanism 203. The base 201 is fixedly mounted on the top guide bracket assembly 300, such as Figure 2 As shown. An electrode plate 207 is provided on the base 201. The wind speed identification sensor rotating mechanism 203 is rotatably connected to the base 201 and is located above the electrode plate 207. The wind speed identification sensor rotating mechanism 203 can contact the electrode plate 207 through rotation energy and cause charge flow, so that electrons move between the electrode plate 207 and the wind speed identification sensor rotating mechanism 203, and the transfer of electrons forms a current, thereby enabling the wind speed identification sensor rotating mechanism 203 to accurately reflect the changes in external excitation (wind force and wind speed) through periodic charge transfer, thereby identifying wind speed data, and the formation of the above-mentioned current enables the wind speed identification sensor rotating mechanism 203 to move in coordination with the electrode plate 207 to achieve the conversion of wind energy into electrical energy.

[0060] In some specific embodiments, Figure 4, Figure 5 and Figure 6 As shown, the wind speed identification sensor rotating mechanism 203 includes a rotating shaft and a plurality of blades 211. The rotating shaft is mounted on the base 201. The plurality of blades 211 are fixedly connected to the outside of the rotating shaft at intervals. The extended end of each blade 211 is connected to a nanofilm 206. Under the rotation of the rotating shaft, the nanofilm 206 of each blade 211 contacts the electrode plate 207 in turn. Since each blade 211 is arranged outside the rotating shaft at intervals, and as shown in FIG. Figure 6 As shown, after the nanofilm 206 on each blade 211 of the wind speed identification sensor rotating mechanism 203 fully contacts the electrode plate 207 and completes pre-charging, periodic and intermittent contact with the electrode plate 207 can ensure that the electrons on the electrode plate 207 are periodically transferred to the nanofilm 206 on the blade 211, thereby forming a current. Moreover, the periodic contact process can also cause the direction of current movement to change. Therefore, as the wind speed identification sensor rotating mechanism 203 continues to rotate, the nanofilm 206 on the blade 211 is driven to periodically contact the electrode plate 207, so that periodic charge transfer occurs between the nanofilm 206 and the electrode plate 207, and then periodic charge transfer occurs between the electrode plate 207 and the ground level.

[0061] In some specific embodiments, Figure 4 , Figure 5 and Figure 6 As shown, the base 201 includes a bottom plate and a pair of vertical plates. The bottom plate is fixedly connected to the top guide bracket assembly 300 to achieve reliable fixation of the base 201 and the top guide bracket assembly 300. Preferably, the bottom of the bottom plate is paved with a rubber base 202 to play a role in fixing and anti-slip. A pair of vertical plates are vertically connected to both sides of the bottom plate, and a channel for airflow to pass through is left between the pair of vertical plates. The channel is equivalent to being enclosed by the bottom plate and a pair of vertical plates, and the top of the channel is open, and the top plate can also be designed separately to be closed.

[0062] In some specific embodiments, Figure 6 As shown, the surface of the bottom plate at one end of the channel is paved with an electrode plate 207, and the two ends of the rotating shaft are respectively connected to a pair of standing plates, and the rotating shaft is horizontally placed above the electrode plate 207. This structural setting enables the wind speed identification sensor rotating mechanism 203 and the electrode plate 207 to be installed at the same end of the channel, and the channel can be used to guide the airflow and more accurately and reliably identify the wind speed data by sight, and the blade 211 and the electrode plate 207 can be reliably accurately contacted to achieve charge transfer, thereby playing a role in efficient power generation.

[0063] It should be noted that the nanofilm 206 is preferably made of FEP nanomaterial, and the electrode plate 207 is preferably a copper plate. Since the FEP nanofilm 206 and the electrode plate 207 made of copper have different affinities for electrons, they are two positive and negative friction materials with large differences in the triboelectric sequence table, so that the nanofilm 206 and the electrode plate 207 can be reliably driven by rotation to contact and friction, and then generate electricity by means of electron transfer to form current. The materials of the nanofilm 206 and the electrode plate 207 are not limited to the FEP nanofilm 206 and the copper electrode, and any combination of the two positive and negative friction material combinations with large differences in the triboelectric sequence table can also be selected, as long as the nanofilm 206 and the electrode plate 207 made of the two materials can induce electron transfer through friction to form current generation. Preferably, the surface of the FEP film can be microstructured, so that the contact surface between the FEP nanofilm and the copper electrode can be further effectively improved.

[0064] It should be noted that the extended end of the blade 211 preferably has a curvature 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 setting enables the extended end of the blade 211 to periodically form partial surface contact with the electrode plate 207, which can increase the contact area and improve the charging and power generation efficiency.

[0065] It should be noted that the blade 211 is connected to the rotating shaft and is located between a pair of vertical 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 is used as an extended end to form the blade 211 structure. The nanofilm 206 is connected to the extended end of the blade 211 through a plurality of fasteners 208. Preferably, the fastener 208 is a screw. This structural setting can ensure that the airflow flows through the channel and can contact each rotating blade 211 more evenly, expand the contact area, thereby improving the charging and power generation efficiency, and can also increase the accuracy and timeliness of wind speed identification.

[0066] It should be noted that the preferred rotating shaft includes a sleeve 204 and a shaft core 205. The sleeve 204 is sleeved outside the shaft core 205. The sleeve 204 is constructed as a cylindrical barrel structure, and a number of fins extending outward are evenly distributed on the outside of the sleeve 204, and the ends of the fins are connected to the above-mentioned nanofilm 206, so as to form the above-mentioned several blades 211 on the outside of the sleeve 204. Preferably, the shaft core 205 of the rotating shaft is provided with threaded holes at both ends, and a pair of through holes are provided on a pair of vertical plates of the base 201 to determine the position for installing the rotating shaft, and the pair of through holes are coaxially arranged to ensure that the axis of the rotating shaft is perpendicular to the channel length direction of the base 201. The locking nut 210 is passed through a side vertical plate and screwed and fixed in the threaded hole at the end of the shaft core 205, so as to ensure that when the airflow passes through the wind speed identification sensor rotating mechanism 203, the sleeve 204 of the rotating shaft rotates around the shaft core 205 driven by the airflow, and the shaft core 205 remains stationary under the fixing action of the locking nut 210. In order to improve the connection reliability between the locking nut 210 and the vertical plate and increase the friction, it is preferred to add a gasket 209 between the locking nut 210 and the vertical plate.

[0067] It should be noted that the bottom plate of the base 201 and the base 202 are preferably coaxially penetrated with a mounting hole 212. The base 201 of the wind speed identification mechanism 200 can be connected to the roof of the vehicle by a connecting structure passing through the mounting hole 212, such as a bolt.

[0068] The following references Figures 7 to 16 The specific working state of the wind speed identification mechanism 200 is described in detail.

[0069] In the embodiment of the present invention, the working state of the wind speed identification mechanism 200 includes an initial state (refer to Figure 7 shown), pre-charge state (reference Figures 8 to 10 shown) and power generation induction state (reference Figures 11 to 15 as shown).

[0070] When the wind speed identification mechanism 200 is in a static initial state without external wind excitation. The wind speed identification mechanism 200 in the initial state can identify that there is no external wind energy, and the wind speed identification mechanism 200 is in a static state. In this state, Figure 7 As shown, the nano film 206 of the wind speed identification mechanism 200 is located above the electrode plate 207, and the two are not in contact with each other, and no charge transfer will occur at this time.

[0071] When external wind force drives the wind speed identification mechanism 200 to rotate, the wind speed identification mechanism 200 enters a working state and respectively undergoes a pre-charging state and a power generation induction state.

[0072] The wind speed identification mechanism 200 is in a pre-charge state, such as Figure 8As shown, the wind speed identification sensor rotating mechanism 203 starts to rotate under the drive of external wind force, and the attached nano film 206 and the electrode plate 207 contact and rub against each other. Therefore, when the two positive and negative friction materials with large differences contact each other, as shown in FIG. Figure 8 and Fig. 9 As shown, the surfaces of the electrode plate 207 and the nano film 206 carry positive charges and negative charges respectively. Since the nano film 206 is made of FEP nano material in the embodiment of the present invention, and FEP nano material is a stationary material, even if Fig.10 After the copper electrode plate 207 is separated from each other, the friction charge attached to the nanofilm 206 is not easy to disappear, and the negative electrical characteristics can be retained for a long time. Therefore, the wind speed identification mechanism 200 in the pre-charge state can identify the existence of external wind energy, and the wind speed identification mechanism 200 drives the continuous transfer of charge to convert wind energy into electrical energy.

[0073] After the nanofilm 206 has undergone the above-mentioned pre-charge state, it reaches the negative electrical characteristic saturation state and is in a relatively static and non-contact state with the electrode plate 207. Fig.11 As shown, at this time, the electrode plate 207 and the connected ground electrode maintain electrostatic balance, and no charge transfer occurs. When the wind continues to provide external excitation, the nanofilm 206 with negative electrical characteristics contacts the electrode plate 207, and the potential balance state is broken; in order to balance the potential difference, the electrons in the external circuit flow from the electrode plate 207 to the ground electrode, so that the external circuit outputs an electrical signal, as shown in Fig.12 As shown; until the nanofilm 206 is in full contact with the electrode plate 207, the electron transfer is maximized, that is, Fig.13 As shown in FIG. 2 , when the wind speed identification sensor rotating mechanism 203 continues to rotate, the nano film 206 and the electrode plate 207 begin to separate. Fig.14 As shown, electrons flow from the ground electrode to the copper electrode, and the direction of the current changes; until the nanofilm 206 and the electrode plate 207 are in a relatively static state and do not contact each other, that is, Fig.15 As shown. Therefore, with the continuous rotation of the wind speed identification sensor rotating mechanism 203, each nanofilm 206 intermittently undergoes the above process with the electrode plate 207, thereby causing periodic charge transfer between the electrode plate 207 and the ground pole, so the electrical signal output of the wind speed identification mechanism 200 can accurately reflect the external excitation change, that is, the wind speed change, thereby obtaining real-time wind speed data, and in this process, the external circuit connected to the ground level outputs an electrical signal to achieve power generation. Therefore, the wind speed identification mechanism 200 in the power generation induction state can identify the existence of external wind energy and drive the periodic transfer of charge, thereby obtaining wind speed data and generating electricity.

[0074] It should be noted that if Fig.16As shown, as the wind speed increases, the number of voltage pulses per unit time will increase and the voltage value will also increase.

[0075] It can be seen that compared with the prior art, the top air guide control system and the air guide hood equipped with the air guide system described in the embodiment of the present invention not only identify and detect environmental data such as wind speed and vehicle speed, but also can better reduce turbulence and rear drag during vehicle driving with the help of the connection structure between the air guide hood and the air guide system; and the structure of the top air guide bracket assembly 300 provided in the air guide hood can make multi-dimensional adjustments to parameters such as the elevation angle and opening height of the top air guide plate 100, and use the control unit to organically combine the elevation angle control and environmental information to achieve more precise control. Moreover, compared with the prior art, the air guide system has more diversified functions and can make full use of the surrounding environmental resources, thereby using the wind speed identification mechanism 200 as a generator to achieve self-generation of the air guide system, so that the air guide system has independent power generation capability relative to the vehicle body circuit system and has independence.

[0076] The tractor provided in the embodiment of the present invention is equipped with the top flow control system as described above; or is equipped with the deflector as described above.
