Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to an installation bracket and a flow guiding device based on a flow guiding device. Background Technology

[0002] With the development of commodity trade, the utilization rate of transportation vehicles is increasing. The improvement in power and speed of transportation vehicles, as well as the diversification of transportation modes, have played a positive role in promoting commodity circulation and economic development. Transportation vehicles need to overcome multiple resistances during operation, including rolling resistance and air resistance. Air resistance is the aerodynamic force experienced by a vehicle during operation; the magnitude of this resistance depends on factors such as the vehicle's speed, shape, and air density. As vehicle speed increases, air resistance also increases significantly. To avoid affecting vehicle turning, existing heavy trucks maintain a certain gap between the tractor and trailer. During vehicle operation, the faster the speed, the faster the airflow velocity in the gap between the trailer and the tractor. Air from various directions collides here, disrupting the streamlines, direction, and velocity of the airflow, thus creating turbulence and generating significant pressure drag and a vacuum zone. This vacuum zone exerts resistance on the cargo box behind, significantly increasing the vehicle's wind resistance. Since the existing fairings are all fixed, the gaps between different sizes of trailers and cargo boxes cannot be fully adapted, which causes resistance to the cargo box during driving, thereby increasing the vehicle's power loss.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Example 1

[0040] like Figure 1 As shown, a mounting bracket based on a flow guiding device includes:

[0041] Mounting bracket body 10,

[0042] First guide vane bracket 11, the first guide vane bracket 11 is pivotally connected to the mounting bracket body 10;

[0043] Support bracket 12, one end of which is connected to the output end of the drive device, and the other end of which is fixedly connected to the first guide plate bracket 11. The support bracket 12 switches between an extended working state and a retracted working state under the action of the drive device.

[0044] Indicatively, such as Figure 2 As shown, the support bracket 12 includes a drive tube 122 that accommodates a drive rod 121. One end of the drive rod 121 is connected to the output end of the drive device, and the other end of the drive rod 121 is fixedly connected to one end of a first support rod 123. The other end of the first support rod 123 is movably connected to the movable end of a second support rod 124. The fixed end of the second support rod 124 is connected to the first guide plate bracket 11. The first support rod 123 is provided with a first hinge connection point 125. The first hinge connection point 125 is sleeved on the mounting bracket body rod 111 and connected to the first predetermined position of the mounting bracket body 10.

[0045] It should be noted that the first predetermined position can be set according to the actual situation and is not limited here. The first predetermined position is intended to limit the transmission direction of the driving force output by the drive device, ensuring that the first support rod 123 and the drive rod 121 are in the same plane. Further, the first support rod 123 can be an L-shaped support rod. The crossbeam end (short section) of the first support rod 123 is connected to the drive rod 121, and the vertical end (long section) of the first support rod 123 is connected to the second support rod 124. The intersection of the crossbeam end and the vertical end of the first support rod 123 forms the first hinge connection point 125.

[0046] Its specific working principle is as follows: Under the action of the driving device, the movable end of the driving rod 121 extends out of the driving tube 122. The driving rod 121 drives one end of the first support rod 123 to move away from the driving tube 122. Based on the limitation of the mounting bracket body 10 (because the first hinge connection point 125 is hinged to the mounting bracket body 10), the first support rod 123 pulls the movable end of the second support rod 124 to move towards the driving tube 122. Since the first guide plate bracket 11 is pivotally connected to the mounting bracket body 10, in the state that the movable end of the second support rod 124 moves towards the driving tube 122, the fixed end of the second support rod 124 drives the first guide plate bracket 11 to pivot, so that the first guide plate bracket 11 extends away from the mounting bracket body 10 along a positive slope or a straight slope. Conversely, when the movable end of the drive rod 121 is retracted into the drive tube 122, the first guide plate bracket 11 is driven to pivot so that the distance between the distal end of the first guide plate bracket 11 and the mounting bracket body 10 is minimized.

[0047] When the support bracket 12 is in the extended state, the first guide plate bracket 11 extends away from the mounting bracket body 10 along a positive slope or a straight slope.

[0048] When the support bracket 12 is in the retracted state, the distance between the far end of the first guide plate bracket 11 and the mounting bracket body 10 is minimized.

[0049] A mounting bracket based on a flow-guiding device is applied to a tractor unit. It switches between an extended and a retracted state depending on the actual application environment. When the mounting bracket is equipped with corresponding flow-guiding plates, in the extended state, the flow-guiding plates form a three-dimensional space to fill the gap between the tractor unit and the trailer, maintaining them as a relatively unified unit. Air is isolated by the flow-guiding device, preventing it from exerting resistance on the trailer and thus preventing turbulence from forming on the sides of the semi-trailer, thereby reducing wind resistance and fuel consumption. In the retracted state, the flow-guiding plates stack on top of each other, reducing the three-dimensional space and facilitating vehicle operations.

[0050] It should be noted that the distal end of the first guide vane bracket 11 is the end away from the mounting bracket body 10, and the proximal end of the first guide vane bracket 11 is the end that is pivotally connected to the mounting bracket body 10.

[0051] As a further preferred embodiment, a first support abutment connection point is provided at one end of the first support rod 123, and a second support abutment connection point matching the first support abutment connection point is provided on the second support rod 124. When the first support abutment connection point matches the second support abutment connection point, the included angle between the first support rod 123 and the second support rod 124 is within the range of 170° to 175°, and the first support rod 123 and the second support rod 124 are in a self-locking state, at which time the support bracket 12 operates in an extended state. When the first support abutment connection point is away from the second support abutment connection point, the first support rod 123 and the second support rod 124 are in an unlocked state, at which time the support bracket 12 operates in a non-extended state.

[0052] As a further preferred embodiment, a mounting bracket, such as Figure 3 As shown, the first guide vane bracket 11 includes a first bracket body 110, a first wing bracket 13 and a second wing bracket 14 pivotally connected to the first bracket body 110, and a transmission device 15 matched with the first wing bracket 13 and the second wing bracket 14.

[0053] The transmission device 15 drives the first wing plate support 13 and the second wing plate support 14 to move so that the first wing plate support 13 and the second wing plate support 14 switch between an extended state and a folded state.

[0054] Furthermore, the transmission device 15 includes a transmission motor 150 and a first transmission rod 151 and a second transmission rod 152 that are directly fixedly connected to the transmission motor 150.

[0055] The first transmission rod 151 is connected to the first transmission screw 154 through the first universal joint 153. A first hinge assembly 16 matching the first transmission screw 154 is provided on the first transmission screw 154. The first hinge assembly 16 is fixedly connected to the first wing plate bracket 13. The first wing plate bracket 13 is connected to the first bracket body 110 through the first connecting hinge.

[0056] The second transmission rod 152 is connected to the second transmission screw 156 through the second universal joint 155. A second hinge assembly (not shown in the figure) matching the second transmission screw 156 is provided on the second transmission screw 156. The second hinge assembly is fixedly connected to the second wing plate bracket 14. The second wing plate bracket 14 is connected to the first bracket body 110 through the second connecting hinge.

[0057] Its specific working principle is as follows: Taking the folding and flipping of the first wing plate bracket 13 as an example, during the process of the first drive motor driving the first transmission rod 151 to rotate, the first transmission rod 151 drives the first transmission screw 154 to rotate through the first universal joint 153. During the rotation of the first transmission screw 154, the first hinge assembly 16 is displaced. During the displacement of the first hinge assembly 16, the first wing plate bracket 13 is driven to extend and fold relative to the first bracket body 110 with the first hinge as the pivot axis.

[0058] Furthermore, the first hinge assembly 16 includes,

[0059] A first hinge bracket 160 is provided with a first nut 161, which is fitted onto the first transmission screw 154.

[0060] The first L-shaped fixed bracket 162 is fixedly connected to the first hinge bracket 160 at its fixed end.

[0061] The first pivoting connection bracket 163 has a movable end connected to one end of the first L-shaped fixed bracket 162, and the other end of the first pivoting connection bracket 163 is connected to the movable end of a second L-shaped fixed bracket 164. The fixed end of the second L-shaped fixed bracket 164 is connected to the first wing plate bracket 13.

[0062] Furthermore, the working principle of the first hinge assembly 16 is as follows: Taking folding as an example, during the rotation of the first transmission screw 154, the first transmission screw 154 drives the first nut 161 to move away from the first support body 110 along the first transmission screw 154. That is, the first hinge support 160 moves away from the first support body 110 along the first transmission screw 154. During the movement of the first hinge support 160, it drives the first L-shaped fixed support 162 to move away from the first support body 110. At this time, because the first connecting hinge and the first L-shaped fixed support 162 change the transmission direction of the driving force through the first pivot connecting support 163 and the second L-shaped fixed support 164, the fixed end of the second L-shaped fixed support 164 drives the first wing plate support 13 to pivot to achieve the folding purpose. Conversely, when the first transmission screw 154 drives the first nut 161 to move closer to the first support body 110 along the first transmission screw 154, the first wing plate support 13 pivots to achieve the unfolding purpose. The working state of the first wing plate bracket 13 can be controlled by adjusting the rotation direction of the lead screw.

[0063] As a further preferred embodiment, an installation bracket further includes: a second deflector bracket 17 and a third deflector bracket (not shown in the figure) identical to the second deflector bracket; the proximal end of the second deflector bracket 17 is connected to the installation bracket body 10 via a lateral pivoting device; and the distal connection point of the second deflector bracket 17 is pivotally connected to the first bracket body 110 via a second pivoting bracket 19.

[0064] The second pivot bracket 19 controls the second guide plate bracket 17 to switch between an extended state and a retracted state.

[0065] like Figure 4 As shown, the second pivot bracket 19 includes a first universal joint connecting rod 190. One end of the first universal joint connecting rod 190 is connected to the first bracket body 110 via a lateral pivot universal joint, and the other end of the first universal joint connecting rod 190 is connected to the second guide plate bracket 17 via a ball joint 191. The ball joint 191 and the first universal joint connecting rod 190 are designed to change the direction of drive force transmission.

[0066] The working principle of the second pivot bracket 19 is as follows: When the distal end of the first bracket body 110 moves away from the mounting bracket body 10 under the action of the support bracket 12, the first bracket body 110 drives the first universal joint connecting rod 190 to push the second guide plate to complete the extension. When the distal end of the first bracket body 110 moves closer to the mounting bracket body 10 under the action of the support bracket 12, the first bracket body 110 drives the first universal joint connecting rod 190 to push the second guide plate to complete the folding.

[0067] Example 2

[0068] like Figure 5 As shown, a flow guiding device includes the aforementioned mounting bracket, a first flow guiding plate 21 fixedly connected to the first flow guiding plate bracket, a first wing plate 23 fixedly connected to the first wing plate bracket, and a second wing plate 22 fixedly connected to the second wing plate bracket.

[0069] like Figure 6 As shown, as a further preferred embodiment, the above-mentioned flow guiding device further includes a second flow guiding plate 24 fixedly connected to the second flow guiding plate bracket, and a third flow guiding plate 23 fixedly connected to the third flow guiding plate bracket.

[0070] To illustrate a specific working method, under the action of the driving device, the movable end of the driving rod of the mounting bracket extends out of the driving tube. The driving rod drives one end of the first support rod to move away from the driving tube. Based on the limiting position of the mounting bracket body (because the first hinge connection point is hinged to the mounting bracket body), the first support rod pulls the movable end of the second support rod to move towards the driving tube. Since the first guide plate bracket is pivotally connected to the mounting bracket body, when the movable end of the second support rod moves towards the driving tube, the fixed end of the second support rod drives the first guide plate bracket to pivot, so that the first guide plate bracket moves away from the mounting bracket body along a positive slope or a straight slope. When the first support abutment connection point matches the second support abutment connection point, the first support rod and the second support rod are in a self-locking state, that is, the first guide plate extends away from the mounting bracket body along a positive slope or a straight slope. During the extension movement of the first guide plate or the first guide plate bracket, the first guide plate bracket drives the first universal joint connecting rod to push the second guide plate and the third guide plate to complete the extension. At this time, the first guide plate, the second guide plate and the third guide plate cooperate with each other to fill the gap between the tractor and the carriage.

[0071] Under the action of the driving device, the movable end of the driving rod retracts to the driving tube. The driving rod drives one end of the first support rod to move towards the driving tube. Based on the limiting position of the mounting bracket body, the first support rod pulls the movable end of the second support rod to move away from the driving tube. At this time, with the first support abutment connection point away from the second support abutment connection point, the first support rod and the second support rod are in an unlocked state. With the movable end of the second support rod moving away from the driving tube, the fixed end of the second support rod drives the first guide plate bracket to pivot, so that the distance between the distal end of the first guide plate bracket and the mounting bracket body is minimized. During the retraction of the first guide plate or the first guide plate bracket, the first guide plate bracket drives the first universal joint connecting rod to push the second guide plate and the third guide plate to complete the retraction. At this time, the first guide plate, the second guide plate, and the third guide plate fold together, and the three-dimensional space occupied by the first guide plate, the second guide plate, and the third guide plate is minimized, so as to facilitate the vehicle to perform large-scale steering operations.

[0072] like Figure 6 As shown, as a further preferred embodiment, the above-mentioned diversion device further includes a bracket housing 25, which forms a space to accommodate the mounting bracket body. When the mounting body is fixedly connected to the tractor, the bracket housing covers the mounting bracket body.

[0073] As a further preferred embodiment, the above-mentioned flow guiding device further includes a connecting device 26, which is provided with a slot that matches the mounting bracket body, in order to ensure the connection stability between the flow guiding device and the tractor.

The automobile has the aforementioned beneficial effects.

[0076] Indicatively, such as Figure 7 As shown, when the flow guiding device 30 is in its extended state, the flow guiding device fills the gap between the tractor and the carriage, such as... Figure 8 As shown, when the flow guiding device 30 is in the retracted state, it does not affect the normal turning or other operations of the vehicle.

[0077] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
