Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a through-type air-guided aerodynamic cabin structure and an all-terrain vehicle. Background Technology

[0002] Compared to vehicles used in ordinary environments, special vehicles used in polar regions face much harsher natural conditions. In the extreme weather conditions of polar blizzards, vehicles are subjected to strong winds from multiple directions, especially crosswinds reaching force 6-8, causing lateral swaying. Furthermore, vehicles must overcome the drag of strong winds, leading to a decrease in speed. To achieve high speeds, methods such as increasing engine power, improving transmission efficiency, and reducing vehicle weight are commonly used. However, these methods do not account for the impact of wind on vehicle speed and fail to reduce the swaying caused by crosswinds.

[0003] Therefore, a through-type aerodynamic cabin structure and an all-terrain vehicle are needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a through-type air-guided aerodynamic cabin structure and an all-terrain vehicle that can reduce the impact of wind on vehicle driving and reduce vehicle sway.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The through-type aerodynamic cabin structure includes:

[0007] The front cabin has a first side panel, which has a first plate portion and a second plate portion. The first plate portion and the second plate portion are not on the same plane, and the first plate portion and the second plate portion are connected to form a first transition portion. The first transition portion is inclined upward along a first direction.

[0008] The rear cabin is hinged to the front cabin. The rear cabin has a second side panel with a third plate portion and a fourth plate portion. The third plate portion and the fourth plate portion are not on the same plane and are connected to form a second transition portion. The second transition portion is inclined upward along a first direction.

[0009] Furthermore, the first plate portion and the third plate portion are on the same plane.

[0010] Furthermore, the second plate portion and the fourth plate portion are on the same plane.

[0011] Furthermore, the first plate portion, the first transition portion, and the second plate portion are an integrated structure.

[0012] Furthermore, the third plate portion, the second transition portion, and the fourth plate portion are an integrated structure.

[0013] Furthermore, the second transition portion includes a first guide portion and a second guide portion connected to each other, the first guide portion and the second guide portion extending along the first direction, the first guide portion being horizontally disposed, and the second guide portion being inclined upwardly disposed.

[0014] Furthermore, the connection between the first transition portion and the first plate portion is arc-shaped, and the connection between the first transition portion and the second plate portion is arc-shaped.

[0015] Furthermore, a wind guide plate is provided on the side of the rear compartment away from the front compartment, the rear compartment has a top inclined plate, the top inclined plate is inclined downward along a first direction, the wind guide plate is connected to and surrounds the two second side plates and the top inclined plate to form a cavity, and the wind guide plate is inclined upward along the first direction on the rear compartment.

[0016] Furthermore, a reinforcing rib is provided in the cavity, one end of which is connected to the air guide plate, and the other end of which is connected to the top inclined plate.

[0017] All-terrain vehicle, including the through-type aerodynamic cabin structure as described above.

[0018] The beneficial effects of this invention are:

[0019] This invention provides a through-type aerodynamic cabin structure. The first side panel of the front cabin is divided into a first panel, a first transition section, and a second panel. The first and second panels are not on the same plane. A rear cabin is connected to the front cabin, and the rear cabin has a second side panel, which is divided into a third panel, a fourth panel, and a second transition section. The third and fourth panels are not on the same plane. Through this design, when the vehicle body is subjected to crosswinds, a wind-breaking effect is created at the first and second transition sections, thereby reducing the lateral forces on the vehicle body. It effectively guides wind from the front and sides along the direction of the first and second transition sections, directing it upwards or backwards, thereby reducing wind resistance and the impact of crosswinds on the cabin, achieving vehicle stability at high speeds in blizzards, and reducing lateral swaying.

[0020] The present invention provides an all-terrain vehicle, including the through-type air-guided aerodynamic cabin structure as described above, which can reduce the impact of wind on vehicle driving and reduce vehicle sway. Attached Figure Description

[0028] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0029] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0030] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a through-type aerodynamic cabin structure and / or a through-type aerodynamic cabin structure can represent: the existence of a single through-type aerodynamic cabin structure, the simultaneous existence of a through-type aerodynamic cabin structure and a through-type aerodynamic cabin structure, or the existence of a single through-type aerodynamic cabin structure. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0031] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0032] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0033] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0034] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0035] When using all-terrain vehicles in polar environments, in order to reduce the impact of wind on vehicle movement and reduce vehicle sway, such as... Figures 1-4 As shown, the present invention provides a through-type aerodynamic cabin structure. The through-type aerodynamic cabin structure includes a front cabin 100 and a rear cabin 200.

[0036] The front compartment 100 has a first side panel 1, which has a first plate portion 11 and a second plate portion 13. The first plate portion 11 and the second plate portion 13 are not on the same plane, and the first plate portion 11 and the second plate portion 13 are connected to form a first transition portion 12. The first transition portion 12 is inclined upward along a first direction. The rear compartment 200 is hinged to the front compartment 100. The rear compartment 200 has a second side panel 2, which has a third plate portion 21 and a fourth plate portion 23. The third plate portion 21 and the fourth plate portion 23 are not on the same plane, and the third plate portion 21 and the fourth plate portion 23 are connected to form a second transition portion 22. The second transition portion 22 is inclined upward along a first direction.

[0037] With the above configuration, when the vehicle body is subjected to crosswinds, a wind-breaking effect is created at the first transition section 12 and the second transition section 22, thereby reducing the lateral forces on the vehicle body. This effectively guides wind forces from the front and sides along the direction of the first transition section 12 and the second transition section 22, directing them upwards or backwards, thereby reducing wind resistance and the impact of crosswinds on the cabin, achieving vehicle stability at high speeds in blizzards, and simultaneously reducing lateral swaying of the vehicle.

[0038] Furthermore, the first panel 11 and the third panel 21 are on the same plane. This arrangement ensures that the incoming airflow from the front passes directly through the third panel 21 after passing through the first panel 11, flowing towards the rear of the vehicle. When the airflow passes through, the third panel 21 is prevented from obstructing the airflow passing through the first panel 11, thereby further reducing wind resistance and preventing the rear compartment 200 from swaying relative to the front compartment 100.

[0039] Furthermore, the second plate portion 13 and the fourth plate portion 23 are on the same plane. This arrangement ensures that incoming airflow from the front passes through the second plate portion 13 and then directly flows to the rear of the vehicle body via the fourth plate portion 23. When airflow passes through, the fourth plate portion 23 is prevented from obstructing the airflow passing through the second plate portion 13, thereby further reducing wind resistance and preventing the rear compartment 200 from swaying relative to the front compartment 100. Simultaneously, the front compartment 100 and the rear compartment 200 form a continuous airflow guiding structure, further reducing wind resistance. In this embodiment, the second plate portion 13 and the fourth plate portion 23 protrude relative to the first plate portion 11 and the second plate portion 13, ensuring that the vehicle chassis has sufficient width to adapt to use in polar environments.

[0040] Furthermore, the first plate portion 11, the first transition portion 12, and the second plate portion 13 are an integral structure. Specifically, sheet metal processing can be used to bend a single piece of steel plate into the first plate portion 11, the first transition portion 12, and the second plate portion 13. By using sheet metal processing to manufacture the first side plate 1, the manufacturing difficulty can be reduced, and the connection strength between the first plate portion 11, the first transition portion 12, and the second plate portion 13 can be guaranteed. Moreover, manufacturing from a single piece of plate can avoid seams and facilitate manufacturing. In other embodiments, welding can also be used to manufacture the first side plate 1, and no further restrictions are placed here.

[0041] Furthermore, the third plate portion 21, the second transition portion 22, and the fourth plate portion 23 are an integrated structure. Similarly, the second side plate 2 can be formed by bending a single piece of steel plate using sheet metal processing. By using sheet metal processing to manufacture the second side plate 2, the manufacturing difficulty can be reduced, and the connection strength between the third plate portion 21, the second transition portion 22, and the fourth plate portion 23 can be guaranteed. Moreover, manufacturing from a single piece of plate avoids seams and facilitates manufacturing. In other embodiments, the second side plate 2 can also be manufactured using welding processes, without further limitations.

[0042] Furthermore, the second transition section 22 includes a first guide section 221 and a second guide section 222 connected to each other. The first guide section 221 and the second guide section 222 extend along a first direction. The first guide section 221 is horizontally arranged, and the second guide section 222 is inclined upward. Through testing, the first transition section 12 creates a wind-breaking effect. When air blown from the front passes through the first guide section 221 and the second guide section 222, the airflow moves upward away from the rear compartment 200, thereby reducing the wind resistance of the rear compartment 200.

[0043] Furthermore, the connection between the first transition portion 12 and the first plate portion 11 is arc-shaped, and the connection between the first transition portion 12 and the second plate portion 13 is also arc-shaped. This arrangement reduces stress concentration at the connections between the first transition portion 12 and the first plate portion 11, and between the first transition portion 12 and the second plate portion 13, while also reducing wind resistance and ensuring effective airflow guidance. Similarly, the connections between the second transition portion 22 and the third plate portion 21, and between the second transition portion 22 and the fourth plate portion 23, also employ arc-shaped structures.

[0044] Furthermore, a guide vane 4 is provided on the side of the rear compartment 200 away from the front compartment 100. The rear compartment 200 has a top inclined plate 3, which is inclined downwards along a first direction. The guide vane 4 is connected to the two second side plates 2 and the top inclined plate 3, forming a cavity. The guide vane 4 is inclined upwards on the rear compartment 200 along the first direction. In the prior art, the rear end of the rear compartment 200 is designed with a right angle or an arc, resulting in poor air guiding capacity and easy formation of turbulence at the rear, affecting driving stability. In this embodiment, by setting the guide vane 4, the airflow at the rear end of the rear compartment 200 can be guided upwards away from the rear end of the rear compartment 200, thereby avoiding the formation of turbulence and improving the stability of vehicle driving. Specifically, the guide vane 4 is connected to the top inclined plate 3 and the two second side plates 2 by welding, which can ensure that the guide vane 4 is stably set on the rear compartment 200.

[0045] Furthermore, a reinforcing rib is fixedly installed in the cavity. One end of the reinforcing rib is connected to the air guide plate 4, and the other end is connected to the top inclined plate 3. By setting the reinforcing rib, the air guide plate 4 can be effectively supported, thereby ensuring that the air guide plate 4 will not bend under the action of airflow, thus avoiding turbulence.

[0046] This embodiment also provides an all-terrain vehicle, including the above-mentioned through-type aerodynamic cabin structure, which can reduce the impact of wind on vehicle driving, reduce vehicle sway, and effectively meet the needs of use in polar environments.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
