[0002] There are many models of existing all-terrain vehicles, including two-door and four-door models, and their door shapes vary. However, the B-pillar of existing all-terrain vehicles has a single shape, which makes it impossible for the existing B-pillar to adapt to the diverse door shapes. As a result, the door cannot fit properly with the B-pillar to seal, leading to low airtightness of the all-terrain vehicle. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an all-terrain vehicle with better sealing performance.
[0004] To achieve the above objectives, this application adopts the following technical solution:
[0005] An all-terrain vehicle includes a frame, body panels, a running gear, a powertrain, seats, doors, pillars, and a bottom frame. The body panels are at least partially mounted on the frame and surround the frame to form a cab. The running gear is at least partially located below the frame. The powertrain is supported by the frame and driven through the running gear. The seats are supported by the frame and include front and rear seats. The doors are at least partially mounted on the frame. The pillars are located between the front and rear seats, and the bottom frame is located below the pillars. The pillars include a lower pillar and an upper pillar located above the lower pillar, with the lower pillar connected to the bottom frame. The lower pillar includes a front side, a rear side, and a sealing surface. The sealing surface is disposed away from the cab. Both the front and rear sides are formed by at least one plane and / or at least one curved surface. The front side contacts the front side of the sealing surface, and the rear side contacts the rear side of the sealing surface. The sealing surface cooperates with the doors to seal the cab.
[0006] Furthermore, the lower support column is a hollow structure, and a cross-sectional plane is defined perpendicular to the height direction of the frame. The cross-section of the lower support column cut by the cross-sectional plane is basically a quadrilateral structure.
[0007] Furthermore, the lower support includes a first stamped part and a second stamped part, which are fixedly connected. The front side, the rear side, and the sealing surface are located on the first stamped part.
[0008] Furthermore, the front and rear sides are basically parallel.
[0009] Furthermore, both the front and rear sides are flat, and the opening formed by the acute angle between the front and rear sides faces downwards.
[0010] Furthermore, the front side is a curved surface that is concave towards the rear side, and the rear side is a curved surface that is concave or convex towards the front side.
[0011] Furthermore, the front side includes at least one first front surface and at least one second front surface, and the rear side includes at least one first rear surface and at least one second rear surface. The first front surface, the second front surface, the first rear surface, and the second rear surface are all planar.

[0012] Furthermore, the front side includes at least one first front surface and at least one second front surface, and the rear side includes at least one first rear surface and at least one second rear surface. The first front surface and the first rear surface are substantially parallel or the opening of the angle they form faces downward. The second front surface is a curved surface that is concave to the second rear surface, and the second rear surface is a curved surface that is concave to or convex to the second front surface.
[0013] Furthermore, the sealing surface is substantially perpendicular to the width direction of the frame.
[0014] Furthermore, the pillar includes a transition pillar located between the upper pillar and the lower pillar, the upper end of the transition pillar being connected to the upper pillar and the lower end of the transition pillar being connected to the lower pillar, and the lower end of the transition pillar being at least partially located in front of the upper end of the transition pillar, such that the lower pillar is at least partially located in front of the upper pillar, and an extended space for increasing the space in front of the rear seats is formed behind the lower pillar.
[0015] The lower support pillar of the aforementioned all-terrain vehicle includes a front side, a rear side, and a sealing surface. Both the front side and the rear side are composed of at least one flat surface and / or at least one curved surface. The front side is connected to the front side of the sealing surface, and the rear side is connected to the rear side of the sealing surface. This increases the structural features of the lower support pillar.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0030] like Figure 1 and Figure 2 As shown, this application provides an all-terrain vehicle 100, which includes a frame 11, body panels 12, a running gear 13, a powertrain 14, a seat 15, and a suspension system 16.
[0031] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, rear, left, right, top, and bottom. In this application, the length direction of the frame 11 refers to... Figure 1 In the fore-and-aft direction, the width direction of the frame 11 refers to... Figure 1 The left and right directions in the middle, and the height direction of frame 11 refers to Figure 1 The up and down directions in the middle.
[0032] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panel 12, running gear 13, powertrain 14, seat 15, and suspension system 16. The body panel 12 is at least partially mounted on the frame 11, protecting internal components of the all-terrain vehicle 100. The running gear 13 is at least partially located beneath the frame 11. Specifically, the running gear 13 includes a front wheel 131 and a rear wheel 132, both connected to the frame 11 via the suspension system 16. The powertrain 14 is drive-connected to the running gear 13. Specifically, the powertrain 14 can be drive-connected to the front wheel 131, the rear wheel 132, or both simultaneously. The seat 15 is at least partially mounted on and connected to the frame 11, supporting the driver and / or passenger. The seat 15 includes a front seat 151 and a rear seat 152.
[0033] Specifically, the body panel 12 and the frame 11 surround to form a cockpit 17, which provides seating space for the driver and / or passengers.
[0034] In this embodiment, the frame 11 includes a pillar 200 and a bottom frame 111. The pillar 200 is located between the front seat 151 and the rear seat 152, and the bottom frame 111 is located below the pillar 200. For the all-terrain vehicle 100, the pillar 200 is the B-pillar of the all-terrain vehicle 100, and the bottom frame 111 is the chassis of the all-terrain vehicle 100.
[0035] In one implementation, the all-terrain vehicle 100 includes a door 18, which is at least partially mounted on the frame 11. With this configuration, when the door 18 is closed, the door 18 cooperates with the frame 11 to seal the driver's cabin 17, thereby ensuring the safety of the personnel inside the driver's cabin 17.
[0036] like Figure 2 and Figure 3As shown, in one implementation, the support column 200 includes a lower support column 21 and an upper support column 22 located above the lower support column 21. The lower support column 21 is connected to the bottom frame 111. The lower support column 21 includes a front side 2111, a rear side 2112, and a sealing surface 2113. Both the front side 2111 and the rear side 2112 are formed by at least one plane and / or at least one curved surface. The sealing surface 2113 is located away from the driver's compartment 17. The front side 2111 is in contact with the front side of the sealing surface 2113, and the rear side 2112 is in contact with the rear side of the sealing surface 2113. The sealing surface 2113 cooperates with the door 18 to seal the driver's compartment 17. With the above settings, the surface shapes of the front side 2111 and the rear side 2112 can be adjusted to increase the types of shapes that the lower support pillar 21 can form, thereby creating sealing surfaces 2113 of different shapes. This allows the support pillar 200 to be adapted to the shape of the door 18, thereby improving the sealing performance between the door 18 and the support pillar 200. In other words, it can improve the sealing performance between the door 18 and the sealing surface 2113, and thus improve the sealing performance of the all-terrain vehicle 100.
[0037] like Figure 3 As shown, the lower support column 21 is a hollow structure. A cross-sectional plane 101 is defined perpendicular to the height direction of the frame 11. The cross-section of the lower support column 21 cut by the cross-sectional plane 101 is essentially a quadrilateral structure. In this application, the cross-sectional plane 101 is perpendicular to the height direction of the frame 11, i.e., perpendicular to... Figure 1 In the vertical direction. With the above configuration, the cross-section of the lower support pillar 21 cut by the cutting plane 101 can be a square, parallelogram, rectangle, trapezoid, etc., thus making the lower support pillar 21 a box-shaped structure. This allows the front side 2111 and rear side 2112 of the lower support pillar 21 to be processed according to requirements, reducing the processing difficulty of the lower support pillar 21. More specifically, the above configuration can adjust the shape of the lower support pillar 21 according to the shape of the door 18, so that the lower support pillar 21 can fit the door 18, thereby facilitating the sealing between the door 18 and the sealing surface 2113, and improving the sealing performance of the all-terrain vehicle 100.
[0038] Specifically, the lower support pillar 21 includes a first stamped part 211 and a second stamped part 212, which are fixedly connected. The front side 2111, the rear side 2112, and the sealing surface 2113 are located on the first stamped part 211. This arrangement allows the lower support pillar 21 to include two stamped parts, thus leveraging the advantage of easily processing stamped parts into different shapes to improve the manufacturing efficiency of the lower support pillar 21. Furthermore, the stamped parts are formed into the required shape by extrusion using a press, which can meet the needs of the all-terrain vehicle 100 for lower support pillars of various shapes, thereby enabling the lower support pillar 21 to adapt to different shapes of the door 18.
[0039] like Figure 4As shown, as an optional implementation, the front side 2111 and the rear side 2112 are substantially parallel. With this configuration, the shape of the lower support column 21, with its front side 2111 and rear side 2112 substantially parallel, is more regular, reducing the difficulty of manufacturing the lower support column 21, thereby improving manufacturing efficiency and reducing manufacturing costs. In this application, the lower support column 21 with the above-described shape is one optional structural type, meeting the needs of the all-terrain vehicle 100 that requires this type of lower support column 21.
[0040] like Figure 5 As shown, as an alternative implementation, both the front side 2111 and the rear side 2112 are planar, and the opening of the angle formed by the front side 2111 and the rear side 2112 faces downwards. With this configuration, the bottom width of the lower support column 21 is greater than the top width, which improves the stability of the lower support column 21 and thus enhances the structural stability of the support column 200. In this application, the lower support column 21 with the above-described shape is one alternative structural type, meeting the needs of the all-terrain vehicle 100 that requires this type of lower support column 21.
[0041] like Figure 6 and 7 As shown, as an alternative implementation, the front side 2111 is a curved surface that is concave to the rear side 2112, and the rear side 2112 is a curved surface that is concave or convex to the front side 2111. Figure 6 The lower support structure 21 is characterized by a front side 2111 concave to a rear side 2112 and a rear side 2112 concave to a front side 2111. Figure 7 The lower support pillar 21 structure is characterized by a front side 2111 recessed towards the rear side 2112 and a rear side 2112 protruding towards the front side 2111. This configuration does not limit the direction or degree of the mutual protrusion or recess between the front side 2111 and the rear side 2112, allowing for a wider range of shapes for the front and rear sides 2111 and 2112 when they are curved surfaces. This enhances the variety of shapes available for the lower support pillar 21, making the pillar 200 more versatile and adaptable to different shapes of the door 18.
[0042] like Figure 8As shown, as an alternative implementation, the front side 2111 includes at least one first front surface 2111a and at least one second front surface 2111b, and the rear side 2112 includes at least one first rear surface 2112a and at least one second rear surface 2112b. The first front surface 2111a, the second front surface 2111b, the first rear surface 2112a and the second rear surface 2112b are all planar. The first front surface 2111a and the first rear surface 2112a are substantially parallel, and the opening of the angle formed by the second front surface 2111b and the second rear surface 2112b is set downward. By configuring the front side 2111 into at least one first front surface 2111a and a second front surface 2111b, and the rear side 2112 into at least one first rear surface 2112a and a second rear surface 2112b, the shape types of the front side 2111 and the rear side 2112 are increased, further broadening the range of possible configurations for the lower support pillar 21. This allows the support pillar 200 to adapt to different shapes of the door 18, thereby improving the sealing performance between the lower support pillar 21 and the door 18. Furthermore, the angle between the second front surface 2111b and the second rear surface 2112b is an acute angle, making the width of the bottom end of the lower support pillar 21 greater than the top end of the second front surface 2111b, thus increasing the stability of the lower support pillar 21.
[0043] like Figures 9 to 12 As shown, as an alternative implementation, the front side 2111 includes at least one first front surface 2111a and at least one second front surface 2111b, and the rear side 2112 includes at least one first rear surface 2112a and at least one second rear surface 2112b. The openings of the first front surface 2111a and the first rear surface 2112a, which are substantially parallel or form an angle, face downwards. The second front surface 2111b is a curved surface that is concave to the second rear surface 2112b, and the second rear surface 2112b is a curved surface that is concave to or convex to the second front surface 2111b.
[0044] Figure 9 In the middle, the first front surface 2111a and the first rear surface 2112a of the lower support 21 are parallel, the second front surface 2111b is curved and recessed towards the second rear surface 2112b, and the second rear surface 2112b is curved and protrudes towards the second front surface 2111b. Figure 10 In the middle, the first front surface 2111a and the first rear surface 2112a of the lower support 21 are parallel, the second front surface 2111b is curved and recessed towards the second rear surface 2112b, and the second rear surface 2112b is curved and recessed towards the second front surface 2111b. Figure 11In the middle, the opening of the angle formed by the first front surface 2111a and the first rear surface 2112a of the lower support 21 faces downward, the second front surface 2111b is curved and recessed towards the second rear surface 2112b, and the second rear surface 2112b is curved and protrudes towards the second front surface 2111b. Figure 12 In the middle, the angle formed by the first front surface 2111a and the first rear surface 2112a of the lower support 21 faces downward, the second front surface 2111b is curved and recessed towards the second rear surface 2112b, and the second rear surface 2112b is curved and recessed towards the second front surface 2111b.
[0045] By adopting the above settings, the specific line shapes and orientations of the first front surface 2111a, the second front surface 2111b, the first rear surface 2112a, and the second rear surface 2112b are not limited, which increases the possibilities of the shapes of the front side 2111 and the rear side 2112, thereby increasing the structural types of the pillar 200, thereby improving the sealing between the pillar 200 and the door 18, and thus improving the safety of the people in the cockpit 17.
[0046] Specifically, the sealing surface 2113 is substantially perpendicular to the width direction of the frame 11. In this application, the sealing surface 2113 is substantially perpendicular to... Figure 1 The vertical sealing surface 2113 can better fit with the door 18, thereby improving the sealing of the cab 17. This prevents mud, water, stones and other impurities from entering the cab during the operation of the all-terrain vehicle 100, thus avoiding mud and water contamination that obstructs the driver's view and stones that could injure the driver, thereby improving the driving safety of the all-terrain vehicle 100.
[0047] like Figure 2 and Figure 13 As shown, the pillar 200 includes a transition pillar 23 located between the upper pillar 22 and the lower pillar 21. The upper end of the transition pillar 23 is connected to the upper pillar 22, and the lower end of the transition pillar 23 is connected to the lower pillar 21. The lower end of the transition pillar 23 is at least partially located in front of the upper end, such that the lower pillar 21 is at least partially located in front of the upper pillar 22. An extension space is formed behind the lower pillar 21 to increase the space in front of the rear seat 152. In this configuration, the lower pillar 21 is further away from the rear seat 152 than the upper pillar 22, thus providing more space between the lower pillar 21 and the rear seat 152, thereby improving passenger comfort in the rear seat 152, and consequently improving the comfort of the all-terrain vehicle 100.
[0048] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
