Description

Technical Field

[0001] The present application relates to the technical field of semi-trailer train body structures, and in particular to a guide assembly with adaptive telescopic adjustment on board and a semi-trailer train. Background Art

[0002] The main drag experienced by vehicles traveling on highways is rolling resistance and aerodynamic drag. Research shows that when a vehicle reaches 80 km / h, aerodynamic drag accounts for approximately half of the total drag. At 150 km / h, aerodynamic drag is two to three times greater than rolling resistance. A 30% reduction in the aerodynamic drag coefficient can reduce fuel consumption by over 10%. Therefore, employing appropriate methods to reduce aerodynamic drag has significant practical and economic value in reducing fuel consumption.

[0003] Due to the large volume of the cargo box of a box truck, there are positive windward surfaces on the front and sides, which will cause the airflow flowing from the front of the vehicle to generate a large positive pressure at the cargo box. The airflow passing through the sides of the cargo box will form a large vortex area at the rear of the vehicle, resulting in greater airflow separation and fluctuations, increasing energy loss, and increasing the front and rear pressure difference resistance of the entire vehicle due to wind resistance. As a result, the vehicle needs to consume more power to overcome the increase in wind resistance when driving, increasing the energy output of the entire vehicle, thereby increasing the fuel consumption of the entire vehicle and reducing power economy.

[0004] In related technologies, heavy-duty tractors are generally equipped with air deflectors (i.e., air deflectors) to effectively reduce the vehicle's drag coefficient and improve its fuel economy. Therefore, the rational use of air deflectors to reduce wind resistance is very helpful in reducing truck fuel consumption. However, when designing heavy-duty tractors, sufficient clearance is often reserved between the cab, air deflector, and cargo box to ensure that the trailer cargo box does not interfere with the cab or the air deflector behind the cab during cornering. The location of the reserved gap often forms vortices during driving, thereby affecting the vehicle's wind resistance and increasing energy consumption. Summary of the Invention

[0005] The embodiments of the present application provide a guide assembly and a semi-trailer vehicle train with adaptive telescopic adjustment to solve the problem in related technologies that the gap reserved between the cab and the guide cover and the cargo box forms eddies during vehicle driving, thereby affecting the wind resistance of the entire vehicle and increasing energy consumption.

[0041] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] The embodiments of the present application provide a deflector assembly and a semi-trailer vehicle train with adaptive telescopic adjustment, which can solve the problem in related technologies that the gap reserved between the cab and the deflector and the cargo box forms eddies during vehicle driving, thereby affecting the wind resistance of the entire vehicle and increasing energy consumption.

[0043] See also Figures 1 to 4 As shown, in a first aspect of an embodiment of the present application, a flow guide assembly with adaptive telescopic adjustment on a vehicle is provided. The flow guide assembly 100 includes:

[0044] The telescopic side deflectors 110 comprise a plurality of vertical deflectors 111 arranged sequentially from front to back. Adjacent vertical deflectors 111 at least partially overlap and are rotatably connected by a connecting rod assembly 112. Two sets of telescopic side deflectors 110 are provided: one set is located to the left of the reserved gap between the cab 210 and the cargo box 220, and the other set is located to the right of the reserved gap between the cab 210 and the cargo box 220.

[0045] The top telescopic air deflector 120 includes a telescopic spoiler 121 located on the top of the two sets of side telescopic air deflectors 110. The front end and rear end faces of the telescopic spoiler 121 are provided with mounting structures. The telescopic spoiler 121 is located at the top of the reserved gap between the cab 210 and the cargo box 220. The mounting structure is used to connect the telescopic spoiler 121 between the cab 210 and the cargo box 220.

[0046] The vehicle-mounted, adaptively retractable air deflector assembly 100 of the present application is used to close the reserved gap between the cab 210 and the cargo box 220. The side telescopic air deflectors 110 adaptively extend or shorten according to the vehicle's turning range during cornering without affecting the vehicle's free steering. Furthermore, two adjacent vertical air deflectors 111 can rotate relative to each other via a connecting rod assembly 112 to avoid mutual interference. The side telescopic air deflectors 110 direct airflow from the front of the cargo box 220 to the sides of the box, preventing the formation of large airflow vortices in front of the box 220. This reduces the aerodynamic pressure differential resistance of the vehicle, lowers vehicle energy consumption, and improves vehicle power and economy.

[0047] The top telescopic shroud 120 is equipped with a telescopic spoiler 121 located on top of the side telescopic shroud 110. This spoiler 121 adopts a corrugated structure design, ensuring that the top telescopic shroud 120 can be compressed or stretched according to the angle between the cab 210 and the cargo box 220 during cornering, without affecting the vehicle's free turning and avoiding the risk of deformation and damage to the rigid spoiler structure. The top telescopic shroud 120 directs airflow from the front of the cargo box 220 to the rear of the cargo box 220, preventing the formation of large air vortices in front of the cargo box 220. This reduces the aerodynamic pressure differential resistance of the entire vehicle, lowering vehicle energy consumption and improving vehicle power and economy.

[0048] In some alternative embodiments: See Figure 4 As shown, the embodiment of the present application provides a deflector assembly that is adaptively retractable and adjustable with the vehicle. The deflector assembly 100 has multiple vertical deflectors 111 of the same height. The width of the vertical deflectors 111 increases from front to back, and the rearmost vertical deflector 111 of two adjacent vertical deflectors 111 is located inside the frontmost vertical deflector 111. The number and width of the vertical deflectors 111 are specifically set based on the size of the reserved gap between the cab 210 and the cargo box 220. This allows the vertical deflectors 111 to guide air within the reserved gap between the cab 210 and the cargo box 220 and to flexibly extend or shorten to meet the vehicle's minimum turning radius.

[0049] The vertical deflectors 111 of the present embodiment are thin-walled plastic parts. The width of the multiple vertical deflectors 111 increases from front to back, so that the width of the vertical deflectors 111 near the cargo box 220 is greater than that of the vertical deflectors 111 near the cab 210. Consequently, when the cargo box 220 rotates about the saddle on the tractor, the vertical deflectors 111 near the cargo box 220 rotate at a greater angle than those near the cab 210. Of the two adjacent vertical deflectors 111, the rearmost vertical deflector 111 is located inside the frontmost vertical deflector 111, thereby preventing external airflow from entering the reserved gap along the gap between the two adjacent vertical deflectors 111.

[0050] In some alternative embodiments: See Figure 3 、 Figure 7 and Figure 8 As shown, an embodiment of the present application provides a deflector assembly with adaptive telescopic adjustment that can be adjusted with the vehicle. The deflector assembly 100 includes a connecting rod assembly 112 that is rotatably connected between two adjacent vertical deflectors 111 and located at the same height. The front connecting rod 113 and the rear connecting rod 114 are parallel to each other and spaced apart. The two adjacent vertical deflectors 111, the front connecting rod 113, and the rear connecting rod 114 together form a four-bar linkage. The two adjacent vertical deflectors 111 are rotatably connected to each other by the front connecting rod 113 and the rear connecting rod 114, so that the two adjacent vertical deflectors 111 can move toward or away from each other, thereby allowing multiple vertical deflectors 111 to freely extend or shorten.

[0051] In some alternative embodiments: See Figure 3 、 Figure 7 and Figure 8 As shown, an embodiment of the present application provides a deflector assembly that is adaptively telescopically adjustable with the vehicle. The deflector assembly 100 is provided with multiple groups of connecting rod assemblies 112, and the multiple groups of connecting rod assemblies 112 are sequentially spaced along the height direction of the vertical deflector 111. The front connecting rod 113 and the rear connecting rod 114 are of the same length, and both ends of the front connecting rod 113 and the rear connecting rod 114 are provided with a rotating shaft that is rotatably connected to the vertical deflector 111. The multiple groups of connecting rod assemblies 112 rotatably connect the multiple vertical deflectors 111 in sequence, while ensuring that the multiple vertical deflectors 111 can freely extend or shorten, and at the same time, the multiple vertical deflectors 111 are firmly connected together, thereby improving the structural strength of the multiple vertical deflectors 111 and preventing them from breaking or deforming under the action of airflow.

[0052] In some alternative embodiments: See Figure 3 、 Figure 7 and Figure 8 As shown, an embodiment of the present application provides a vehicle-adaptive air deflector assembly with adaptive telescopic adjustment. The outer wall surface of the middle vertical deflector 111 among the multiple vertical deflectors 111 of the air deflector assembly 100 is provided with an outer hinge point that rotatably connects a front link 113 and a rear link 114. The inner wall surface of the middle vertical deflector 111 among the multiple vertical deflectors 111 is provided with an inner hinge point that rotatably connects the front link 113 and the rear link 114. The distance between the inner hinge point and the front end of the vertical deflector 111 is greater than the distance between the outer hinge point and the front end of the vertical deflector 111.

[0053] In the multi-piece vertical flow deflectors 111 of the embodiments of the present application, an inner hinge point for rotatably connecting the front link 113 and the rear link 114 is provided on the inner wall surface of the vertical flow deflector 111 at the frontmost end, and an inner hinge point for rotatably connecting the front link 113 and the rear link 114 is provided on the outer wall surface of the vertical flow deflector 111 at the rearmost end. Outer hinge points and inner hinge points for rotatably connecting the front link 113 and the rear link 114 are provided on both the outer wall surface and the inner wall surface of the remaining vertical flow deflectors 111, and the distance from the inner hinge point to the front end of the vertical flow deflector 111 is greater than the distance from the outer hinge point to the front end of the vertical flow deflector 111, so that adjacent vertical flow deflectors 111 can be arranged in sequence from front to back.

[0054] In some alternative embodiments: Refer to Figure 4 As shown, the embodiments of the present application provide a flow guiding assembly with vehicle-mounted adaptive telescopic adjustment. The telescopic spoiler 121 of the flow guiding assembly 100 is a rubber corrugated plate, and the telescopic spoiler 121 as a whole has a "C" - shaped structure. Multiple mutually parallel rigid skeletons are embedded in the telescopic spoiler 121, and flanges are provided at both the front and rear ends of the telescopic spoiler 121. The mounting structure includes multiple mounting holes 122 located on the flanges, and mounting brackets 123 formed by the rigid skeletons extending outside the telescopic spoiler 121.

[0055] The telescopic spoiler 121 is a rubber corrugated plate. This rubber corrugated plate is a flexible material itself and has good elastic deformation ability to freely expand and contract. The rubber corrugated plate can also serve as a waterproof mechanism to prevent rainwater from entering the vehicle chassis and keep the vehicle chassis in a dry environment. Multiple mutually parallel rigid skeletons are embedded in the telescopic spoiler 121, and these rigid skeletons are used to enhance the structural stiffness of the telescopic spoiler 121 and prevent the telescopic spoiler 121 from collapsing and deforming due to excessive lateral span. Mounting holes 122 for fixing the telescopic spoiler 121 between the cab 210 and the cargo box 220 are provided on the flanges at both the front and rear ends of the telescopic spoiler 121, and the telescopic spoiler 121 is fixed to the cargo box 220 through the mounting brackets 123.

[0056] Refer to Figures 1 to 3 As shown, in the second aspect of the embodiments of the present application, a semi-trailer truck train is provided. The semi-trailer truck train 200 includes a tractor and a trailer connected to each other. A cargo box 220 fixedly connected thereto is configured on the trailer. A space is provided between the cab 210 of the tractor and the cargo box 220 to provide a turning space between the cab 210 and the cargo box 220. A flow guiding assembly 100 of any of the above embodiments is connected between the cab 210 of the tractor and the cargo box 220. The side telescopic flow deflectors 110 of the flow guiding assembly 100 are located on both sides of the front end of the cargo box 220, and the top telescopic flow deflectors 120 of the flow guiding assembly 100 are located on the top of the front end of the cargo box 220.

[0057] Side deflectors 240 are connected to both sides of the rear end of the cab 210, and a top deflector 230 is located at the top of the rear end of the cab 210. The front end of the telescopic side deflector 110 is connected to the end of the side deflector 240, and the rear end of the telescopic side deflector 110 is connected to the front end of the cargo box 220. The front end of the telescopic top deflector 120 is connected to the end of the top deflector 230, and the rear end of the telescopic top deflector 120 is connected to the front end of the cargo box 220. A plurality of upper brackets 221 for connecting to the telescopic top deflector 120 are located at the top of the front end of the cargo box 220, and a plurality of side brackets 222 for connecting to the telescopic side deflector 110 are located on the sides of the front end of the cargo box 220.

[0058] See also Figures 5 to 8 As shown, when the semi-trailer train 200 is turning left, a left turning angle is formed between the tractor and trailer with the saddle as the rotation axis. At this time, the side telescopic shroud 110 on the left side of the cargo box 220 is shortened, while the side telescopic shroud 110 on the right side of the cargo box 220 is extended. The left end of the top telescopic shroud 120 on top of the cargo box 220 is shortened, while the right end of the top telescopic shroud 120 is extended. When the semi-trailer train 200 is turning right, a right turning angle is formed between the tractor and trailer with the saddle as the rotation axis, and the positions of the side telescopic shroud 110 and the top telescopic shroud 120 are opposite to those described above.

[0059] How it works

[0060] An embodiment of the present application provides a vehicle-adaptive telescopic air guide assembly and a semi-trailer vehicle train. The vehicle-adaptive telescopic air guide assembly 100 of the present application is provided with a side telescopic air guide cover 110, which includes a plurality of vertical air guide plates 111 arranged in sequence from front to back, and two adjacent vertical air guide plates 111 at least partially overlap, and the two adjacent vertical air guide plates 111 are rotatably connected by a connecting rod assembly 112; a top telescopic air guide cover 120, which includes a telescopic spoiler 121 located at the top of the side telescopic air guide cover 110, and the front and rear ends of the telescopic spoiler 121 are provided with mounting structures.

[0061] Therefore, the vehicle-adaptive, telescopically adjustable deflector assembly of the present application is used to close the reserved gap between the cab 210 and the cargo box 220. The side telescopic deflector 110 allows the vehicle to adaptively extend or shorten according to the vehicle's turning range during cornering without affecting the vehicle's free steering. Furthermore, the two adjacent vertical deflectors 111 can rotate relative to each other via the connecting rod assembly 112 to avoid mutual interference. The side telescopic deflector 110 directs the airflow in front of the cargo box 220 to both sides of the cargo box 220, preventing the formation of large airflow vortices in front of the cargo box 220, thereby reducing the aerodynamic pressure differential resistance of the entire vehicle, reducing the vehicle's energy consumption, and improving the vehicle's power and economy.

[0062] The top telescopic shroud 120 is equipped with a telescopic spoiler 121 located on top of the side telescopic shroud 110. This spoiler 121 adopts a corrugated structure design, ensuring that the top telescopic shroud 120 can be compressed or stretched according to the angle between the cab 210 and the cargo box 220 during cornering, without affecting the vehicle's free turning and avoiding the risk of deformation and damage to the rigid spoiler structure. The top telescopic shroud 120 directs airflow from the front of the cargo box 220 to the rear of the cargo box 220, preventing the formation of large air vortices in front of the cargo box 220. This reduces the aerodynamic pressure differential resistance of the entire vehicle, lowering vehicle energy consumption and improving vehicle power and economy.
