[0061] 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. Example

[0062] like Figure 1 As shown, a mounting bracket based on a flow guiding device includes:

[0063] The driving device includes at least one driving output terminal;

[0064] The drive bracket 1 includes a drive input end, a first drive output end, and a second drive output end. The drive input end of the drive bracket 1 is connected to the output end of the drive device. The drive bracket 1 switches between an extended working state and a retracted working state under the action of the drive device.

[0065] When the drive bracket 1 is in the extended state, the first drive output end and the second drive output end extend in the horizontal direction so that the distance between the first drive output end and the second drive output end is minimized;

[0066] When the drive bracket 1 is in the retracted state, the first drive output end and the second drive output end retract in the horizontal direction to maximize the distance between the first drive output end and the second drive output end.

[0067] Schematic, the driving device can be formed by a first driving motor 2. The output end of the first driving motor 2 is connected to the driving input end of the driving bracket 1, that is, the driving rod 21 of the first driving motor 2 is connected to the driving input end of the driving bracket 1. During the process of the driving rod 21 moving away from the first driving motor 2, the driving rod 21 applies a driving force to the driving input end so that the first driving output end and the second driving output end extend in the horizontal direction, and the distance between the first driving output end and the second driving output end is minimized; at this time, the driving bracket 1 works in the extended state. During the process of the driving rod 21 moving towards the first driving motor 2, the driving rod 21 applies a pulling force to the driving input end so that the first driving output end and the second driving output end retract in the horizontal direction, and the distance between the first driving output end and the second driving output end is maximized; at this time, the driving bracket 1 works in the retracted state.

[0068] As a further preferred embodiment, the above-mentioned mounting bracket based on a flow guiding device includes: the driving bracket 1 includes a first driving hinge assembly 11, a second linkage hinge assembly 12 linked with the first driving hinge assembly 11, and a third linkage hinge assembly 13 identical to the second linkage hinge assembly 12. The input end of the first driving hinge assembly 11 is connected to the output end of the first driving motor 2. Under the action of the first driving motor 2, the first driving hinge assembly 11 pushes the second linkage hinge assembly 12 and the third linkage hinge assembly 13 to switch the driving bracket 1 between an extended state and a retracted state.

[0069] The second linkage hinge assembly 12 forms the first drive output end, and the third linkage hinge assembly 13 forms the second drive output end.

[0070] Schematic, during the movement of the drive rod 21 away from the first drive motor 2, the drive rod 21 applies a driving force to the first drive hinge assembly 11. The first drive hinge assembly 11 converts the vertical driving force into a horizontal pushing force, causing the second linkage hinge assembly 12 and the third linkage hinge assembly 13 to extend horizontally, i.e., the second linkage hinge assembly 12 and the third linkage hinge assembly 13 move away from the drive rod, and the distance between the second linkage hinge assembly 12 and the third linkage hinge assembly 13 is minimized. At this time, the drive bracket 1 is in an extended state. During the movement of the drive rod 21 towards the first drive motor 2, the drive rod 21 applies a pulling force to the first drive hinge assembly 11. The first drive hinge assembly 11 converts the vertical pulling force into a horizontal pulling force, causing the second linkage hinge assembly 12 and the third linkage hinge assembly 13 to approach each other horizontally, and the distance between the second linkage hinge assembly 12 and the third linkage hinge assembly 13 is maximized. At this time, the drive bracket 1 is in a retracted state.

[0071] In a schematic way, in actual application, the second linkage hinge assembly 12 can be connected to the second guide plate, and the third linkage hinge assembly 13 can be connected to the third guide plate. When the second linkage hinge assembly 12 moves away from the first drive motor 2, it pushes the second guide plate into a folded state. Similarly, the third linkage hinge assembly 13 also drives the third guide plate into a folded state. At the same time, the second and third guide plates push the first guide plate into a folded state. When the second linkage hinge assembly 12 moves towards the first drive motor 2, it pushes the second guide plate into an extended state. Similarly, the third linkage hinge assembly 13 also drives the third guide plate into an extended state. At the same time, the second and third guide plates push the first guide plate into an extended state. At this time, the first, second, and third guide plates cooperate with each other to fill the gap between the tractor and the carriage.

[0072] like Figure 2 As shown, as a further preferred embodiment, the above-mentioned mounting bracket based on the flow guiding device includes: the first drive hinge assembly 11 includes a first link 111, a second link 112, a third link 113, a fourth link 114, a fifth link 115 and a sixth link 116;

[0073] The first link is connected to the second link at the first predetermined position 1111 at the third predetermined position 1123 at the second predetermined position 1112 at the first link at the third predetermined position 1133 at the third predetermined position 1133 at the first link at the third predetermined position 1113 at the second linkage hinge assembly 12.

[0074] The second link at the second predetermined position 1122 connects to the fourth link at the second predetermined position 1142, and the second link at the first predetermined position 1121 connects to the fifth link at the second predetermined position 1152;

[0075] The third link at the second predetermined position 1132 connects to the fourth link at the first predetermined position 1141, and the third link at the first predetermined position 1131 connects to the fifth link at the first predetermined position 1151;

[0076] The fourth link is connected to the sixth link at the third predetermined position 1143, and the fifth link is connected to the sixth link at the second predetermined position 1161 at the third predetermined position 1153.

[0077] The third link at the first predetermined position 1131 connects to the fifth link at the first predetermined position 1151 and is connected to the output end of the first drive motor 2.

[0078] The sixth link is connected to the third linkage hinge assembly 13 at the third predetermined position 1163.

[0079] Schematic representation: the second link 112, the third link 113, and the sixth link 116 are parallel to each other; the first link 111, the fourth link 114, and the fifth link 115 are parallel to each other; the second link 112, the third link 113, the fourth link 114, and the fifth link 115 form a first movable rhombus; the first link 111, the second link 112, the third link 113, and the fourth link 114 form a second movable rhombus; and the second link 112, the fourth link 114, the fifth link 115, and the sixth link 116 form a third movable rhombus. The first and second movable rhombuses share the third link 113, and the first and third movable rhombuses share the second link 112. The first vertex of the first movable rhombus is fixedly connected to the drive rod 21. During the deformation of the first movable rhombus as the drive rod 21 moves away from the drive device (extending out of the drive device), the first movable rhombus applies a force to the second and third movable rhombuses, causing them to deform and thus causing the first link 111 and the sixth link 116 to move away from the drive rod 21. During the deformation of the first movable rhombus as the drive rod 21 moves towards the drive device (retracting into the drive device), the first movable rhombus applies a force to the second and third movable rhombuses, causing them to deform and thus causing the first link 111 and the sixth link 116 to move towards the drive rod 21.

[0080] As a further preferred embodiment, the above-mentioned mounting bracket based on the flow guiding device further includes a T-shaped groove 3;

[0081] The connection point between the second predetermined position 1132 of the third link and the first predetermined position 1141 of the fourth link forms a first connection protrusion.

[0082] The connection point between the first predetermined position 1121 of the second link and the second predetermined position 1152 of the fifth link forms a second connection protrusion.

[0083] The connection point between the second predetermined position 1122 of the second link and the second predetermined position 1142 of the fourth link forms a third connection protrusion.

[0084] The first and second connecting protrusions are housed within the first groove 31 of the T-shaped slide 3; the third connecting protrusion is housed within the second groove 32 of the T-shaped slide 3. The T-shaped slide limits the movement of the first, second, and third connecting protrusions, ensuring that the first, second, and third movable rhombuses move along a predetermined direction during deformation, thus guaranteeing the stability of their extension or contraction.

[0085] It should be noted that the first link 111, the second link 112, the third link 113, the fourth link 114, the fifth link 115, and the sixth link 116 can be formed from the same link, wherein the distance between the first predetermined position and the second predetermined position is close, and the distance between the third predetermined position and the second predetermined position is far; the first link 111, the second link 112, the third link 113, the fourth link 114, the fifth link 115, and the sixth link 116 can also be formed from different links, with the aim of realizing the conversion of the direction of the pushing force or the pulling force through the first link 111, the second link 112, the third link 113, the fourth link 114, the fifth link 115, and the sixth link 116.

[0086] like Figure 3As shown, as a further preferred embodiment, the above-mentioned mounting bracket based on the flow guiding device includes: the second linkage hinge assembly 12 includes a first linkage connecting rod 120, a first linkage rod 121, and a second linkage rod 122. One end of the first linkage connecting rod 120 is connected to the first drive hinge assembly 11, and the other end is connected to one end of the first linkage rod 121. The other end of the first linkage rod 121 is connected to the first hinge point of the second linkage rod 122, and the second hinge point 1212 of the first linkage rod is connected to the flow guiding bracket body 20. Schematic, the working principle of the second linkage hinge assembly 12 is as follows: When the first drive hinge assembly 11 drives the second linkage hinge assembly 12, and the first drive hinge assembly 11 is in its extended state, the first connecting rod 111 drives the first linkage connecting rod 120 to move away from the drive device. During the movement of the first linkage connecting rod 120, it drives the first linkage rod 121 to move. Since the second hinge point of the first linkage rod 121 is connected to the flow guide bracket body 20, during the movement of the first linkage connecting rod 120 away from the drive device, the second linkage rod 122 moves towards the drive device. To achieve the purpose of folding the mounting bracket, similarly, when the first driving hinge assembly 11 drives the second linkage hinge assembly 12, and the first driving hinge assembly 11 is in the retracted state, the first connecting rod 111 drives the first linkage connecting rod 120 to move towards the driving device. During the movement of the first linkage connecting rod 120, it drives the first linkage rod 121 to move. Since the second hinge point of the first linkage rod 121 is connected to the guide bracket body 20, during the movement of the first linkage connecting rod 121 towards the driving device, the second linkage rod 122 moves towards the driving device to achieve the purpose of unfolding.

[0087] like Figure 4 As shown, in a further preferred embodiment, the aforementioned mounting bracket based on a flow guiding device includes: the drive bracket 1 further comprising a first lateral flow guiding bracket 14 matched with the second linkage hinge assembly 12, and a second lateral flow guiding bracket 15 matched with the third linkage hinge assembly 13. Schematably, the other end of the second linkage rod 122 is fixedly connected to the first lateral flow guiding bracket. The second linkage rod 122 is rigidly connected to the first lateral flow guiding bracket 14. The third linkage hinge assembly 13 is also rigidly connected to the second lateral flow guiding bracket 15. Example

[0088] like Figure 5 As shown, this utility model further provides a flow guiding device, which includes the mounting bracket based on the flow guiding device described in any one of the above embodiments, and also includes...

[0089] The guide bracket body 40 is fixedly connected to the mounting bracket;

[0090] First guide plate 41, the first guide plate 41 is pivotally connected to the guide bracket body 40;

[0091] The second guide plate 42 includes a first guide sub-plate 421 and a second guide sub-plate 422 connected to the first guide sub-plate 421 via a first guide hinge. The first guide sub-plate 421 is movably connected to the first guide plate 41. The second guide sub-plate 422 is pivotally connected to the first drive output end of the mounting bracket and pivotally connected to the guide bracket body 40.

[0092] The third guide plate 43 includes a third guide sub-plate 431 and a fourth guide sub-plate 432 connected to the third guide sub-plate 431 via a second guide hinge. The third guide sub-plate 431 is movably connected to the first guide plate 41. The fourth guide sub-plate 432 is pivotally connected to the second drive output end of the mounting bracket and pivotally connected to the guide bracket body 40.

[0093] Furthermore, the first guide plate 41 is connected to the second guide plate 42 via a second hinge, and the first guide plate 41 is connected to the third guide plate 43 via a third hinge.

[0094] List one specific implementation method,

[0095] During the movement of the drive rod away from the drive device, the drive rod applies a driving force to the first drive hinge assembly. The first drive hinge assembly converts the vertical driving force into a horizontal pushing force, causing the second and third linkage hinge assemblies to extend horizontally. That is, the second and third linkage hinge assemblies move away from the drive rod, and the distance between the second and third linkage hinge assemblies is minimized. At this time, the drive bracket is in an extended state, and the first linkage hinge assembly pulls the first lateral guide bracket closer to the guide bracket body. At this time, the first lateral guide bracket pulls the first guide subplate and the second guide subplate into a folded state (e.g., Figure 7 (As shown) At the same time, the first guide plate pulls the first guide plate into a folded state. Similarly, the third linkage hinge assembly pulls the second lateral guide bracket close to the guide bracket body. At this time, the second lateral guide bracket pulls the third and fourth guide plates into a folded state, and the third guide plate pulls the first guide plate into a folded state.

[0096] As the drive rod moves toward the drive device, it applies a pulling force to the first drive hinge assembly. The first drive hinge assembly converts the vertical driving force into a horizontal pushing force, causing the second and third linkage hinge assemblies to retract horizontally. That is, the second and third linkage hinge assemblies move toward the drive rod, and the distance between them gradually increases until it reaches its maximum. At this time, the drive bracket is in a retracted state, and the first linkage hinge assembly drives the first lateral guide bracket away from the guide bracket body. The first lateral guide bracket then pulls the first and second guide plates into a flipped state (e.g.,...). Figure 6 As shown in the diagram, simultaneously, the first guide plate pulls the first guide vane into a flipped state. Similarly, the third linkage hinge assembly pulls the second lateral guide bracket away from the guide bracket body. At this time, the second lateral guide bracket pulls the third and fourth guide plates into a flipped state, while the third guide plate pulls the first guide plate into a flipped state. The guide device fills the gap between the tractor and the carriage. Example

[0097] This utility model further provides an automobile, including a mounting bracket based on a flow guiding device as described in any of the above claims, wherein the flow guiding device is fixedly connected between the tractor and the cargo box, including the technical solution described in Embodiment 1 or Embodiment 2 above. The automobile has the aforementioned beneficial effects.

[0098] Indicatively, such as Figure 9 As shown, when the flow guiding device is in the flipped state, the flow guiding device fills the gap between the tractor and the carriage, such as... Figure 8 As shown, when the deflector is in the folded state, it does not affect the vehicle's normal turning or other operations. Example

[0099] To further optimize the mounting bracket structure, this embodiment provides another mounting bracket based on a flow guiding device, such as... Figure 10As shown, the driving device includes a second driving motor 52 and a third driving motor 53 identical to the second driving motor 52. The driving bracket 51 includes a third linkage hinge assembly 513 and a fourth linkage hinge assembly 514 identical to the third linkage hinge assembly 513. The third linkage hinge assembly 513 includes a third linkage connecting rod 5131 and a third linkage rod 5132. One end of the third linkage connecting rod 5131 is connected to the output end of the second driving motor 52, and the other end is connected to one end of the third linkage rod 5132. The second hinge point of the third linkage connecting rod 5131 is connected to the mounting bracket body. The third linkage rod 5132 forms the output end of the third linkage hinge assembly.

[0100] Under the action of the second drive motor, the working state of the third linkage component switches between an extended state and a retracted state;

[0101] Under the action of the third drive motor, the working state of the fourth linkage component switches between an extended state and a retracted state.

[0102] To illustrate with an example, taking the second drive motor 52 and the third linkage hinge assembly 513 as examples, when the second drive motor 52 drives the third linkage connecting rod 5131 of the third linkage hinge assembly 513, since the second hinge point of the third linkage connecting rod 5131 is connected to the mounting bracket body, the two ends of the third linkage connecting rod 5131 move in opposite directions. That is, while the end of the third linkage connecting rod 5131 connected to the second drive motor 52 moves away from the second drive motor 52, the end of the third linkage connecting rod 5131 connected to the third linkage rod 5132 moves towards the second drive motor 52, and vice versa.

[0103] When the second drive motor applies a pushing force to the third linkage hinge assembly and the third drive motor applies a pushing force to the fourth linkage hinge assembly, the distance between the third linkage hinge assembly and the fourth linkage hinge assembly is minimized, and the mounting bracket operates in a retracted state. When the second drive motor applies a pulling force to the third linkage hinge assembly and the third drive motor applies a pulling force to the fourth linkage hinge assembly, the distance between the third linkage hinge assembly and the fourth linkage hinge assembly is maximized, and the mounting bracket operates in an extended state.

[0104] Furthermore, the mounting bracket body is provided with a second motor cavity 520 for accommodating the second drive motor and a third motor cavity 530 for accommodating the third drive motor. The second motor cavity and the third motor cavity are fixedly mounted on the mounting bracket body, which is intended to facilitate the installation of the second drive motor and the third drive motor, and the output ends of the second drive motor and the third drive motor are rotatable. Example

[0105] To further optimize the mounting bracket structure, this embodiment provides another mounting bracket based on a flow guiding device, such as... Figure 11 As shown, in this embodiment, the extension and retraction of the mounting bracket structure is achieved by a screw drive. Specifically, in the above-mentioned mounting bracket based on a flow guiding device, the driving device includes a fourth driving motor 60, and the driving bracket includes a fifth linkage hinge assembly 61 and a sixth linkage hinge assembly 62 that is the same as the fifth linkage hinge assembly 61.

[0106] The fifth linkage hinge assembly 61 includes a fifth linkage connecting rod, a fifth linkage rod movably connected to the fifth linkage connecting rod, and a fifth secondary linkage rod 614 movably connected to the fifth linkage rod;

[0107] The fifth linkage connecting rod includes a first directional lead screw 610, which is fixedly connected to the fourth drive motor 60, a first lead screw nut 611 that matches the first directional lead screw 610, the first lead screw nut 611 being fixedly disposed at the first end of the first push rod 612, the second end of the first push rod 612 being connected to the fifth linkage rod 613, and the second hinge point of the fifth linkage rod being connected to the mounting bracket.

[0108] The second hinge point of the fifth linkage rod is connected to the mounting bracket body, and the fifth linkage rod forms the output end of the fifth linkage hinge assembly.

[0109] Under the action of the fourth drive motor, the working states of the fifth and sixth linkage hinge components switch between extended and retracted states.

[0110] Schematably, the sixth linkage hinge assembly 62 includes a sixth linkage connecting rod, a sixth linkage rod movably connected to the sixth linkage connecting rod, and a sixth secondary linkage rod 624 movably connected to the sixth linkage rod;

[0111] The sixth linkage connecting rod 62 includes a second direction lead screw 620 and a second lead screw nut 621 that matches the second direction lead screw 620. The second lead screw nut 621 is fixedly disposed at the first end of the second push rod 622, and the second end of the second push rod 622 is connected to the sixth linkage rod 623.

[0112] The first-direction lead screw drives the first lead screw nut to move in the first direction, and the second-direction lead screw drives the second lead screw nut to move in the second direction. The movements of the first lead screw nut and the second lead screw nut are synchronized but in opposite directions.

[0113] Taking the fifth linkage hinge assembly as an example, during the rotation of the fourth drive motor, the first directional lead screw rotates. At this time, the first lead screw nut passively moves in a direction away from the fourth drive motor. Simultaneously, the first lead screw nut drives the first push rod in the same direction. The first push rod drives one end of the fifth linkage rod 613 in the same direction. Since the second hinge point of the fifth linkage rod is connected to the mounting bracket body, while one end of the fifth linkage rod 613 connected to the first push rod moves away from the fourth drive motor, the other end of the fifth linkage rod 613 moves towards the fourth drive motor. The reverse is also true. The principle of the sixth linkage hinge is the same, and will not be elaborated here.

[0114] When the fourth drive motor applies a pushing force to the fifth linkage hinge assembly, the distance between the fifth and sixth linkage hinge assemblies is minimized, and the mounting bracket operates in a retracted state. When the fourth drive motor applies a pulling force to the fifth linkage hinge assembly, the distance between the fifth and sixth linkage hinge assemblies is maximized, and the mounting bracket operates in an extended state.

[0115] It should be noted that this fourth embodiment can be used in conjunction with the second and third embodiments, and its working principle will not be elaborated here.

[0116] 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. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
