Description

Technical Field

[0001] This application belongs to the technical field of air deflectors, and particularly relates to a vehicle air deflector and a vehicle. Background Technology

[0002] Energy consumption during vehicle operation is not only due to the engine, but also greatly related to the vehicle's drag coefficient. Due to the vehicle's windward airflow characteristics, installing a fairing on the cab roof is the most effective and simplest measure to reduce air resistance, without requiring changes to the main structural components of the cab and cargo box.

[0003] The fairing can direct airflow to a higher position, which greatly improves the streamline index of the front windshield of the trailer above the cab and the discontinuity of airflow in the gap between the cab and the trailer. It reduces air turbulence, improves the production efficiency and fuel economy of semi-trailers, and also reduces vehicle pollution and noise.

[0004] Since the cargo height varies depending on actual needs, the fairing needs to be adjusted. In related technologies, the adjustment range of the fairing is relatively small. Summary of the Invention

[0005] This application aims to at least partially solve the technical problem of the limited adjustment range of fairings in related technologies. To this end, this application provides a vehicle fairing and a vehicle.

[0006] In a first aspect, embodiments of this application provide a vehicle fairing, comprising:

[0007] A support member for connection to the roof of a vehicle, the support member having a storage slot;

[0008] A lifting component and a lifting drive assembly, wherein the lifting drive assembly is located in the storage slot and connected to the support component and the lifting component, and is used to drive the lifting component to lift.

[0009] A first flow guide and a second flow guide, wherein the first flow guide is movably connected to the second flow guide, one side of the second flow guide is rotatably connected to the lifting member about a first rotating shaft, and one side of the first flow guide is rotatably connected to the support member about a second rotating shaft parallel to the first rotating shaft;

[0010] Under the drive of the lifting drive assembly, the lifting member moves up and down, causing the second guide member to move relative to the first guide member, and the first guide member rotates relative to the support member, so that the first guide member and the second guide member together form a guide surface.

[0011] In some embodiments, when the lifting drive assembly is in the retracted state, the lifting member, the first guide member, and the second guide member can be simultaneously located within the storage slot.

[0012] In some embodiments, when the lifting drive assembly is in a retracted state, the lifting member, the first guide member, and the second guide member together shield the opening of the mounting slot.

[0013] In some embodiments, under the drive of the lifting drive assembly, the lifting member rises to a set position and is in a horizontal state or in an inclined state tilted toward the driving direction of the vehicle.

[0014] In some embodiments, the lifting drive assembly includes a drive assembly and a support assembly, wherein the support assembly includes a first support rod and a second support rod rotatably connected at the center;

[0015] The first support rod has a first end and a second end arranged opposite to each other along a first direction. The first end is rotatably connected to the support member, and the second end is slidably connected to the lifting member.

[0016] The second support rod has a third end and a fourth end arranged opposite to each other along a second direction. The third end is rotatably connected to the lifting member, and the fourth end is connected to the drive assembly. The drive assembly is used to drive the fourth end to move toward the first end or away from the first end, so that the lifting member rises or falls.

[0017] In some embodiments, the drive assembly includes a drive member, a lead screw, and a slider, wherein the first end and the fourth end are spaced apart along the axial direction of the lead screw;

[0018] The lead screw is rotatably connected to the support member, the driving member is used to drive the lead screw to rotate around the axis of the lead screw, the slider is threadedly connected to the lead screw and slidably connected to the support member along the axis of the lead screw, and the fourth end of the second support rod is rotatably connected to the slider.

[0019] In some embodiments, two support components are provided, which are arranged opposite to each other along the first axis and are located on both sides of the lifting member, respectively.

[0020] The drive assembly further includes a first transmission member and a second transmission member rotatably connected to the support member. One end of the first transmission member and the second transmission member are both connected to the drive member, and the other end of the first transmission member and the second transmission member are respectively connected to the lead screws of the two support assemblies.

[0021] In some embodiments, the vehicle fairing further includes a detector and a controller, the detector being used to detect the height of cargo inside the vehicle's cargo compartment, and both the detector and the lifting drive assembly being electrically connected to the controller;

[0022] The controller is used to control the lifting drive assembly to operate and adjust the height of the lifting component when the height of the cargo is higher than the height of the vehicle front, so that the height of the lifting component is not lower than the height of the cargo.

[0023] The controller is also configured to control the lifting drive assembly to retract when the height of the cargo is lower than the height of the vehicle roof.

[0024] Secondly, embodiments of this application also provide a vehicle, including a roof and the vehicle fairing described in the first aspect above, wherein a support member of the vehicle fairing is installed on the roof along the vehicle's forward direction, and the second fairing member is located in front of the lifting member.

[0025] In some embodiments, the roof has a mounting groove, and the support member of the vehicle fairing is located in the mounting groove; when the lifting drive assembly is in the retracted state, the highest point of the vehicle fairing is not higher than the highest point of the roof along the height direction of the vehicle.

[0026] The present invention has at least the following beneficial effects:

[0027] The vehicle fairing includes a support, a lifting component, a lifting drive assembly, a first guide component, and a second guide component. The lifting drive assembly is used to drive the lifting component to rise and fall. The first guide component is movably connected to the second guide component. One side of the second guide component is rotatably connected to the lifting component around a first rotating shaft. One side of the first guide component is rotatably connected to the support component around a second rotating shaft parallel to the first rotating shaft.

[0028] In the vehicle fairing of this application, both the first and second guide members can play a guiding role. Since the first and second guide members are movably connected, the first guide member is rotatably connected to the support member, and the second guide member is rotatably connected to the lifting member, the total length of the first and second guide members is different when the lifting member is at different heights, and the rotation radius of the whole formed by the first and second guide members around the second axis is different. That is to say, the rotation radius of the whole formed by the first and second guide members around the second axis can be changed synchronously with the height of the support member. This makes the height of the end of the second guide member connected to the lifting member more flexibly adjustable, and its height adjustment range is larger. Therefore, compared with related technologies, the adjustment range of the vehicle fairing of this application is larger. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that all directional indications in the embodiments of this invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction relationship between two components, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances. In addition, the descriptions involving "first," "second," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0042] Energy consumption during vehicle operation is not only due to the engine, but also greatly related to the vehicle's drag coefficient. Due to the vehicle's windward airflow characteristics, installing a fairing on the cab roof is the most effective and simplest measure to reduce air resistance, without requiring changes to the main structural components of the cab and cargo box.

[0043] The fairing can direct airflow to a higher position, which greatly improves the streamline index of the front windshield of the trailer above the cab and the discontinuity of airflow in the gap between the cab and the trailer. It reduces air turbulence, improves the production efficiency and fuel economy of semi-trailers, and also reduces vehicle pollution and noise.

[0044] Because cargo height varies depending on actual needs, the fairing needs to be adjusted. A relevant technology can be found in Chinese invention patent publication CN 219277655 U, where a driving device drives the fairing body (reference number 1 in the patent) to rotate along a certain axis. The fairing body rotates along a fixed axis, and the height adjustment range of the fairing body is limited by the distance between the side of the fairing body away from the axis. Furthermore, due to structural limitations, the fairing body in this related technology cannot descend further after reaching a certain height; it always protrudes from the vehicle roof. When the height of the cargo inside the vehicle is lower than the roof height, or when there is no cargo in the vehicle, the fairing actually increases air resistance during vehicle operation, increasing energy consumption.

[0045] Therefore, in related technologies, fairings suffer from the technical problem of limited adjustment range. This application provides a vehicle fairing and a vehicle, which can at least partially solve the technical problem of limited fairing adjustment range.

[0046] This application is described below with reference to the accompanying drawings and specific embodiments:

[0047] like Figure 1 As shown, the vehicle fairing 100 includes a support 110, a lifting component 120, a lifting drive assembly 130, a first guide component 140, and a second guide component 150.

[0048] The support member 110 is used to connect to the roof 200 of the vehicle 1000, and the support member 110 has a storage slot 110a.

[0049] For trucks, the roof 200 refers to the cab roof, and the vehicle fairing 100 is installed on the cab roof. Of course, depending on the actual needs, the user can also install the vehicle fairing 100 of this application on the roof of a bus, car, etc., and this application does not impose any restrictions.

[0050] The opening of the storage slot 110a faces upward. The storage slot 110a is used to support and fix the lifting drive assembly 130. When the vehicle fairing 100 is in the retracted state, it can be used to accommodate the lifting component 120, the lifting drive assembly 130, the first guide component 140, and the second guide component 150.

[0051] The lifting drive assembly 130 is located in the storage slot 110a and is connected to the support member 110 and the lifting member 120, and is used to drive the lifting member 120 to lift.

[0052] The lifting drive assembly 130 has various structural types, including electric push rods, hydraulic cylinders, motors with gears and racks, etc., and is not limited here.

[0053] The first guide member 140 is movably connected to the second guide member 150. One side of the second guide member 150 is rotatably connected to the lifting member 120 around the first rotating shaft, and one side of the first guide member 140 is rotatably connected to the support member 110 around the second axis parallel to the first axis.

[0054] The side of the first guide member 140 away from the second guide member 150 is rotatably connected to the support member 110, that is... Figure 1 The left side of the first guide member 140. The side of the second guide member 150 away from the first guide member 140 is rotatably connected to the lifting member 120, that is... Figure 1 The right side of the second guide element 150.

[0055] Driven by the lifting drive assembly 130, the lifting member 120 moves up and down, and drives the second guide member 150 to move relative to the first guide member 140. The first guide member 140 rotates relative to the support member 110, so that the first guide member 140 and the second guide member 150 together form a guide surface.

[0056] The first guide member 140 and the second guide member 150 are movably connected so that the second guide member 150 can rotate around the first rotating shaft and move up and down synchronously with the lifting member 120. The first guide member 140 and the second guide member 150 can be rotatably connected or slidably connected. In some embodiments, the first guide member 140 and the second guide member 150 are rotatably connected around a third rotating shaft parallel to the first rotating shaft. In some embodiments, the first guide member 140 and the second guide member 150 are slidably connected; specifically, the first guide member 140 and the second guide member 150 are slidably connected along a line perpendicular to the line connecting the first and second rotating shafts. For ease of description, this application will use the slidable connection of the first guide member 140 and the second guide member 150 as an example.

[0057] like Figure 1As shown, during the unfolding of the vehicle fairing 100, the lifting drive assembly 130 drives the lifting member 120 to rise, and the second guide member 150 rotates and rises. Specifically, the side of the second guide member 150 that is rotatably connected to the lifting member 120 rises synchronously with the lifting member 120. The second guide member 150 also rotates along the first rotating shaft. As the lifting member 120 rises, the height of the lifting member 120 gradually increases, and the angle between the second guide member 150 and the lifting member 120 gradually decreases. At the same time, the second guide member 150 also slides along the first guide member 140, and the first guide member 140 also rotates around the second rotating shaft. The overall length of the second guide member 150 and the first guide member 140 increases.

[0058] like Figure 2 As shown, during the retraction of the vehicle fairing 100, the lifting drive assembly 130 drives the lifting member 120 to descend, and the second guide member 150 rotates and descends. Specifically, the side of the second guide member 150 that is rotatably connected to the lifting member 120 descends synchronously. The second guide member 150 also rotates along the first rotating shaft. As the lifting member 120 descends, the height of the lifting member 120 gradually decreases, and the angle between the second guide member 150 and the lifting member 120 gradually increases. At the same time, the second guide member 150 also slides along the first guide member 140, and the first guide member 140 also rotates around the second rotating shaft. The overall length of the second guide member 150 and the first guide member 140 becomes shorter.

[0059] In the vehicle fairing 100 of this application, both the first guide member 140 and the second guide member 150 can play the role of guiding airflow. Since the first guide member 140 and the second guide member 150 are movably connected, the first guide member 140 and the support member 110 are rotatably connected, and the second guide member 150 is rotatably connected to the lifting member 120, the total length of the first guide member 140 and the second guide member 150 is different when the lifting member 120 is at different heights. The rotation radius of the whole formed by the first guide member 140 and the second guide member 150 around the second axis is different. That is to say, the rotation radius of the whole formed by the first guide member 140 and the second guide member 150 around the second axis can be changed synchronously with the height of the support member 110. This makes the height of the end of the second guide member 150 connected to the lifting member 120 more flexibly adjustable, and its height adjustment range is larger. Therefore, compared with related technologies, the adjustment range of the vehicle fairing 100 of this application is larger.

[0060] With this design, when the cargo compartment of vehicle 1000 contains goods and the height of the goods is higher than the height of the vehicle roof 200, the lifting drive assembly 130 can drive the lifting component 120 to rise above the height of the goods, so that the vehicle fairing 100 can be deployed, and the air can be guided by the first guide component 140 and the second guide component 150, thereby helping to reduce the air resistance encountered by vehicle 1000 during driving.

[0061] When there is no cargo stored in the cargo compartment of vehicle 1000, or when the stored cargo is no higher than the height of the roof 200, the lifting drive assembly 130 can drive the lifting component 120 to descend to the lowest point, causing the fairing to fold and be in a retracted state, reducing the frontal area of ​​the lifting component 120, the first guide component 140 and the second guide component 150, thereby reducing the air resistance experienced by vehicle 1000.

[0062] like Figure 2 As shown, in some embodiments, when the lifting drive assembly 130 is in the retracted state, the lifting member 120, the first guide member 140, and the second guide member 150 can be simultaneously located in the storage tank 110a.

[0063] In other words, when the lifting drive assembly 130 drives the lifting component 120 to descend to the lowest point, the lifting component 120, the first guide component 140 and the second guide component 150 can be simultaneously located in the storage tank 110a.

[0064] In this way, when there is no cargo stored on the vehicle 1000, or the stored cargo is no higher than the height of the vehicle roof 200, or when the vehicle 1000 passes through a height restriction area, the lifting drive assembly 130 can drive the lifting component 120 to descend to the lowest point, so that the lifting component 120, the first guide component 140 and the second guide component 150 are simultaneously located in the storage slot 110a, without extending out of the storage slot 110a. This allows the vehicle 1000 equipped with the vehicle fairing 100 of this application to pass through the height restriction area, so that the lifting component 120, the first guide component 140 and the second guide component 150 will not be subject to air resistance or will be subject to less air resistance, thus greatly reducing the air resistance encountered by the vehicle 1000 during driving.

[0065] In some embodiments, when the lifting drive assembly 130 is in the retracted state, the lifting member 120, the first guide member 140, and the second guide member 150 together shield the opening of the mounting groove 200a.

[0066] In other words, when the lifting drive assembly 130 drives the lifting component 120 to descend to the lowest point, the lifting component 120, the first guide component 140, and the second guide component 150 together cover the opening of the mounting groove 200a.

[0067] With the lifting drive assembly 130 in the retracted state, the first guide 140, the second guide 150, and the lifting component 120 are all located within the mounting slot 200a, and the first guide 140 and the second guide 150 do not perform their guiding function. With the lifting drive assembly 130 in the retracted state, configuring the lifting component 120, the first guide 140, and the second guide 150 to collectively shield the opening of the mounting slot 200a can, to a certain extent, prevent external rainwater, impurities, dust, etc., from entering the storage slot 110a through the opening when the vehicle fairing 100 is not in operation, thus preventing them from affecting the first guide 140, the second guide 150, the lifting component 120, and the lifting drive assembly 130. This helps extend the service life of the vehicle fairing 100 and ensures its stable operation.

[0068] In some embodiments, sealing elements made of rubber or other materials are provided on the edges of the first guide member 140, the second guide member 150, and the lifting member 120. When the lifting drive assembly 130 is in the retracted state, the sealing elements can seal the gap between the first guide member 140 and the support member 110, the gap between the second guide member 150 and the support member 110, and the gap between the lifting member 120 and the support member 110, preventing rainwater, dust, etc. from entering the storage groove 110a of the support member 110 through the gaps, thus ensuring the stable operation of the vehicle fairing 100.

[0069] In this application, when the lifting drive assembly 130 is in the extended state, at least the first guide member 140 and the second guide member 150 work together to form a guiding surface. As for the lifting member 120, when the lifting drive assembly 130 is in the extended state, it may or may not perform a guiding function; this application does not limit this. If the lifting member 120 does not perform a guiding function, it can be a rod-shaped structure, with one end rotatably connected to the second guide member 150 and the other end connected to the lifting drive assembly 130. The lifting member 120 can also have other structures, and the structures are diverse; this application does not limit this. It is readily understood that when the lifting member 120 does not perform a guiding function, it can be designed with a size, structure, or shape that minimizes wind resistance, thereby reducing the air resistance experienced by the lifting member 120 during vehicle 1000 operation, and thus reducing the air resistance experienced by the vehicle 1000.

[0070] If the lifting component 120 is required to play a guiding role, then when the lifting drive assembly 130 is in the extended state, the first guide component 140, the second guide component 150 and the lifting component 120 work together to form a guiding surface.

[0071] In some implementations, under the drive of the lifting drive assembly 130, the lifting member 120 rises to a set position and is in a horizontal state or tilted state towards the driving direction of the vehicle 1000.

[0072] In other words, when the vehicle fairing 100 is in the deployed state, the lifting member 120 can be in a horizontal state or in an inclined state towards the driving direction of the vehicle 1000. The lifting member 120 can play a guiding role, which helps to improve the guiding effect of the fairing of this application. In the inclined state towards the driving direction of the vehicle 1000, the side of the lifting member 120 closer to the second guide member 150 is lower than the side farther from the second guide member 150. With this design, the first guide member 140, the second guide member 150, and the lifting member 120 together form a guiding surface, which helps to improve the guiding effect of the fairing of this application.

[0073] The first guide member 140 and the second guide member 150 can be flat plate structures or curved plate structures, and similarly, the lifting member 120 can be flat plate structures or curved plate structures, etc., without limitation in this application.

[0074] like Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the lifting drive assembly 130 includes a drive assembly 131 and a support assembly 132. The support assembly 132 includes a first support rod 1321 and a second support rod 1322 rotatably connected at their middle portions. The first support rod 1321 has a first end and a second end that are arranged opposite to each other along a first direction. The first end is rotatably connected to the support member 110, and the second end is slidably connected to the lifting member 120. The second support rod 1322 has a third end and a fourth end that are arranged opposite to each other along a second direction. The third end is rotatably connected to the lifting member 120, and the fourth end is connected to the drive assembly 131. The drive assembly 131 is used to drive the fourth end to move toward or away from the first end, so that the lifting member 120 rises or falls.

[0075] The first direction is the length direction of the first support rod 1321, and the second direction is the length direction of the second support rod 1322. The first support rod 1321 and the second support rod 1322 are rotatably connected at their middle parts, forming an "X" shape. The first support rod 1321 has a first end and a second end that are arranged opposite to each other along the first direction. The first end is rotatably connected to the support member 110, and the second end is slidably connected to the lifting member 120. The second support rod 1322 has a third end and a fourth end that are arranged opposite to each other along the second direction. The third end is rotatably connected to the lifting member 120, and the fourth end is connected to the drive assembly 131. The drive assembly 131 drives the fourth end to move closer to or away from the first end. Figure 4As shown, the upper end of the first support rod 1321 is the second end, and the lower end is the first end; the upper end of the second support rod 1322 is the third end, and the lower end is the fourth end.

[0076] In this way, when the drive assembly 131 drives the fourth end to move toward the first end, the distance between the fourth end and the first end gradually decreases, the angle between the first support rod 1321 and the second support rod 1322 decreases, and the lifting member 120 gradually rises; when the drive assembly 131 drives the fourth end to move away from the first end, the distance between the fourth end and the first end gradually increases, the angle between the first support rod 1321 and the second support rod 1322 increases, and the lifting member 120 gradually descends, thereby realizing the control of the lifting member 120.

[0077] In some embodiments, both the first direction and the second direction are perpendicular to the first axis.

[0078] The lengths of the first support rod 1321 and the second support rod 1322 can be the same or different. When the lengths of the first support rod 1321 and the second support rod 1322 are the same, the lifting member 120 can remain in a horizontal state during the lifting process. When the lengths of the first support rod 1321 and the second support rod 1322 are different, the lifting member 120 can be tilted towards the driving direction of the vehicle 1000.

[0079] like Figure 4 and Figure 5 As shown, in some embodiments, the drive assembly 131 includes a drive member 1311, a lead screw 1312, and a slider 1313. The first end and the fourth end are spaced apart along the axial direction of the lead screw 1312. The lead screw 1312 is rotatably connected to the support member 110. The drive member 1311 is used to drive the lead screw 1312 to rotate around the axis. The slider 1313 is threadedly connected to the lead screw 1312 and slidably connected to the support member 110 along the axial direction of the lead screw 1312. The fourth end of the second support rod 1322 is rotatably connected to the slider 1313.

[0080] The slider 1313 is threadedly connected to the lead screw 1312 and slidably connected to the support member 110. The driving member 1311 drives the lead screw 1312 to rotate. Therefore, under the action of the driving member 1311, the lead screw 1312 can rotate, and the slider 1313 slides along the axial direction of the lead screw 1312 while the lead screw 1312 rotates. The fourth end of the second support rod 1322 is rotatably connected to the slider 1313. Therefore, the fourth end of the second support rod 1322 can move together with the slider 1313. Since the first end and the fourth end are spaced apart along the axial direction of the lead screw 1312, the fourth end can move along the axial direction of the lead screw 1312, and thus move towards the first end or away from the first end.

[0081] like Figure 4 As shown, in some embodiments, two support components 132 are provided, which are arranged opposite each other along a first axis and are located on both sides of the lifting member 120. The drive component 131 also includes a first transmission member 1314 and a second transmission member 1315. One end of the first transmission member 1314 and the second transmission member 1315 are both connected to the drive member 1311, and the other end of the first transmission member 1314 and the second transmission member 1315 are respectively connected to the lead screws 1312 of the two support components 132.

[0082] With this design, the driving component 1311 drives the first transmission component 1314 and the second transmission component 1315 to rotate. The first transmission component 1314 and the second transmission component 1315 respectively drive the two lead screws 1312 to rotate, thereby realizing the lifting of the lifting component 120. The two support components 132 provide support on both sides of the lifting component 120, which helps to improve the stability of the lifting component 120, the first guide component 140 and the second guide component 150.

[0083] In some embodiments, the drive member 1311, the lead screw 1312, the first transmission member 1314 and the second transmission member 1315 are all installed on the bottom wall of the storage tank 110a, the first end of the first support rod 1321 is rotatably connected to the bottom wall of the storage tank 110a, and the drive assembly 131 is located between the two support assemblies 132.

[0084] In some embodiments, the drive component 1311 is a motor, and a bevel gear is mounted on the motor shaft. Bevel gears are also mounted at one end of the first transmission component 1314 and the second transmission component 1315. The bevel gears on the motor mesh with the bevel gears on the first transmission component 1314 and the second transmission component 1315, so that the motor is connected to the first transmission component 1314 and the second transmission component 1315. When the motor shaft rotates, it can drive the first transmission component 1314 and the second transmission component 1315 to rotate.

[0085] In some embodiments, bevel gears are also installed at the other ends of the first transmission member 1314 and the second transmission member 1315, and bevel gears are installed at one end of the two lead screws 1312. The bevel gear at the other end of the first transmission member 1314 meshes with the bevel gear on one of the lead screws 1312, and the bevel gear at the other end of the second transmission member 1315 meshes with the gear on the other lead screw 1312, so that the first transmission member 1314 and the second transmission member 1315 are respectively connected to the two lead screws 1312 for transmission. When the motor shaft rotates, it can simultaneously drive the first transmission member 1314 and the second transmission member 1315 to rotate, thereby simultaneously driving the two lead screws 1312 to rotate, thereby simultaneously driving the two support components 132 to move.

[0086] In some embodiments, the support 110 includes a connected base plate 111 and a side plate 112, the side plate 112 and the base plate 111 being angled together and enclosing a storage groove 110a.

[0087] The side plate 112 and the bottom plate 111 are arranged at an angle, which can be a right angle, an obtuse angle, or an acute angle. The number and shape of the side plates 112 are not limited in this application.

[0088] In some embodiments, the support member 110 is provided with four side plates 112, the bottom plate 111 is rectangular, the side plates 112 and the bottom plate 111 are arranged perpendicularly, and the four side plates 112 are respectively connected to the four sides of the bottom plate 111 to enclose and form a storage groove 110a with a rectangular cross-section.

[0089] In some embodiments, the storage tank 110a has a rectangular cross-section, and the first guide member 140, the second guide member 150, and the lifting member 120 are all rectangular plates. The lifting member 120 is parallel to the base plate 111, and the width of the first guide member 140, the second guide member 150, and the lifting member 120 is the same as the width of the storage tank 110a. When the lifting drive assembly 130 is in the retracted state, the overall length of the first guide member 140, the second guide member 150, and the lifting member 120 is the same as the length of the storage tank 110a, so that when the lifting drive assembly 130 is in the retracted state, the lifting member 120, the first guide member 140, and the second guide member 150 together cover the opening of the mounting slot 200a. Figure 2 As shown.

[0090] In some embodiments, the vehicle fairing 100 further includes a detector 160 and a controller 170. The detector 160 is used to detect the height of the cargo inside the vehicle compartment of the vehicle 1000. The detector 160 and the lifting drive assembly 130 are both electrically connected to the controller 170. The controller 170 is used to control the lifting drive assembly 130 to operate when the height of the cargo is higher than the height of the vehicle front, and adjust the height of the lifting component 120 so that the height of the lifting component 120 is not lower than the height of the cargo.

[0091] Specifically, when the detector 160 detects that the cargo inside the carriage is higher than the height of the front of the vehicle, the detector 160 sends an electrical signal to the controller 170. Based on the electrical signal sent by the detector 160, the controller 160 controls the lifting drive assembly 130 to move, so that the lifting component 120 rises or falls, ensuring that the height of the lifting component 120 is not lower than the height of the cargo. This achieves automatic adjustment of the height of the lifting component 120, which facilitates the use of the vehicle fairing 100 of this application.

[0092] The sensor can be an obstacle detection sensor, which can be positioned on the side of the support 110 away from the second guide member 150. The sensor emits a detection signal towards the cargo. If the sensor emits a detection signal towards the cargo but does not receive a corresponding feedback signal, it is assumed that the cargo height is lower than the current height of the lifting member 120. Conversely, if the sensor emits a detection signal towards the cargo and receives a corresponding feedback signal, it is assumed that the cargo height is greater than or equal to the current height of the lifting member 120.

[0093] In some embodiments, the controller 170 is also configured to control the lifting drive assembly 130 to retract when the cargo height is below the height of the vehicle roof 200.

[0094] Specifically, when detector 160 detects that the height of the cargo inside the vehicle compartment does not exceed the height of the front of the vehicle, detector 160 sends an electrical signal to controller 170. Based on the electrical signal fed back by detector 160, controller 160 controls the lifting drive assembly 130 to retract, causing the lifting component 120, the first guide component 140, and the second guide component 150 to descend to their lowest points, reducing air resistance on the lifting component 120, the first guide component 140, and the second guide component 150, thereby reducing air resistance on the vehicle 1000. In these embodiments, a sensor can also be installed on the roof 200 to detect whether the height of the cargo is lower than the roof 200.

[0095] like Figure 7 , Figure 8 and Figure 9 As shown, based on the same inventive concept, this application embodiment also provides a vehicle 1000, including a roof 200 and the aforementioned vehicle fairing 100. The support member 110 of the vehicle fairing 100 is installed on the roof 200 along the forward direction of the vehicle 1000, and the second fairing member 150 is located in front of the lifting member 120.

[0096] For trucks, the roof 200 refers to the cab roof, and the vehicle fairing 100 is installed on the cab roof. Of course, depending on the actual needs, the user can also install the vehicle fairing 100 of this application on the roof of a bus, car, etc., and this application does not impose any restrictions.

[0097] The second guide member 150 is located in front of the lifting member 120 along the forward direction of the vehicle 1000, so as to ensure that the first guide member 140 and the second guide member 150 can smoothly realize the guiding function.

[0098] In some implementations, the first axis is parallel to the width direction of the vehicle 1000.

[0099] Since the vehicle 1000 includes the vehicle fairing 100 described above in this application, it naturally has all the beneficial effects of the vehicle fairing 100, which will not be elaborated here.

[0100] like Figure 9 As shown, in some embodiments, the roof 200 is provided with a mounting groove 200a, and the support member 110 of the vehicle fairing 100 is located in the mounting groove 200a. When the lifting drive assembly 130 is in the retracted state, the highest point of the vehicle fairing 100 is not higher than the highest point of the roof 200 along the height direction of the vehicle 1000.

[0101] In other words, when the lifting drive assembly 130 drives the lifting component 120 to descend to the lowest position, the entire vehicle fairing 100 is located within the mounting groove 200a, and the vehicle fairing 100 does not protrude from the roof 200.

[0102] In this way, when there is no cargo stored on the vehicle 1000, or the stored cargo is no higher than the height of the roof 200, or when the vehicle 1000 passes through a height restriction area, the lifting drive assembly 130 can drive the lifting component 120 to descend to the lowest point, so that the vehicle fairing 100 does not extend out of the mounting slot 200a. The vehicle fairing 100 is hidden in the mounting slot 200a, so that the vehicle 1000 equipped with the vehicle fairing 100 of this application can pass through the height restriction area, so that the vehicle fairing 100 as a whole will not be affected by air resistance or will be affected by very little air resistance, thus greatly reducing the air resistance encountered by the vehicle 1000 during driving.

[0103] In some embodiments, the upper surface of the support member 110 of the vehicle fairing 100 is flush with the upper surface of the roof 200. When the lifting drive assembly 130 is in the retracted state, the first guide member 140, the second guide member 150 and the lifting member 120 are also flush with the upper surface of the roof 200.
