Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Technology
[0002] All-terrain vehicles (ATVs) are designed for operation in complex terrains and are widely used in agriculture, forestry, military, rescue, and recreational fields. Due to the specific nature of their operating environments, ATVs require high stability and durability. The chassis, as the core structural component of an ATV, plays a crucial role in supporting the vehicle's weight, connecting various parts, and withstanding the impacts and vibrations from the complex terrain.
[0003] To meet the requirements of strength and rigidity, traditional bicycle frames typically use thicker sheet metal materials, resulting in a larger overall frame weight. Furthermore, these sheet metal parts usually only have supporting or connecting functions, leading to a complex frame structure that requires more components to achieve different functions, thus increasing the frame's weight and manufacturing costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an all-terrain vehicle with a highly functional and lightweight chassis.
[0005] This application provides an all-terrain vehicle, including a frame, body panels, a running gear system, and a power system. The frame includes a front frame, a middle frame, and a rear frame connected in sequence. The body panels at least partially cover the frame, and the running gear system is at least partially disposed below the frame. The power system drives the running gear system. The rear frame includes an upper support frame, a lower support frame, and a sheet metal structural member. The upper support frame, lower support frame, and sheet metal structural member enclose a compartment, in which the power system is disposed. One end of the upper support frame is connected to the middle frame, and the other end extends towards the rear of the all-terrain vehicle. The lower support frame is disposed below the upper support frame, with one end connected to the middle frame and the other end extending towards the rear of the all-terrain vehicle. The sheet metal structural member is disposed on the rear frame, with one end connected to the lower part of the upper support frame and the other end connected to the upper part of the lower support frame. The sheet metal structural member has multiple functional holes.
[0006] In at least one embodiment, the total area of the plurality of functional holes accounts for 10% to 30% of the area of the sheet metal structural component.
[0007] In at least one embodiment, when viewed along the front-rear direction of the all-terrain vehicle, the power system and the sheet metal structure at least partially overlap, and the functional holes penetrate the sheet metal structure along the front-rear direction of the all-terrain vehicle.
[0008] In at least one embodiment, the rear frame includes a trailer hitch that is detachably suspended from one of the functional holes.
[0009] In at least one embodiment, the edge of the functional hole is provided with a flange, and the flange protrudes from the surface where the functional hole is located by a distance of 0.5 mm to 3 mm.
[0010] In at least one embodiment, the sheet metal structural member has an arcuate surface that protrudes toward the power system.
[0011] In at least one embodiment, when viewed from the rear to the front of the all-terrain vehicle, at least a portion of the sheet metal structure is observed, and the sheet metal structure is provided with reinforcing ribs.
[0012] In at least one embodiment, the rear frame includes a locking member that connects a sheet metal structural member to an upper support frame and a lower support frame via a functional hole.
[0013] In at least one embodiment, the sheet metal structural component is integrally formed.
[0014] In at least one embodiment, the all-terrain vehicle includes a rear compartment disposed above an upper support frame, and at least a portion of the rear compartment is projected onto a sheet metal structure along the vertical direction of the all-terrain vehicle.
[0015] The all-terrain vehicle of this application features sheet metal structural components that can cooperate with upper and lower support frames to form a housing compartment for the power system, facilitating its installation. Functional holes in the sheet metal structural components reduce the overall weight of the rear frame, and the power system can also dissipate heat through these holes. Located at the rear of the frame, the sheet metal structural components not only reinforce the rear load-bearing capacity of the frame but also protect the power system, making it less susceptible to impacts in harsh driving conditions and improving driving safety. The application of multifunctional sheet metal components achieves an integrated design of weight reduction, support, and protection, thereby reducing the weight and manufacturing cost of the all-terrain vehicle.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.
[0024] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0025] like Figure 1 As shown, an embodiment of this application provides an all-terrain vehicle 100. In the embodiments of this application, the type of all-terrain vehicle 100 is not specifically limited. For example, the all-terrain vehicle 100 can be, but is not limited to, a three-wheeled all-terrain vehicle, a four-wheeled all-terrain vehicle, a snow all-terrain vehicle, etc. The all-terrain vehicle 100 can be applied to emergency rescue, extreme sports, and other application scenarios.
[0026] See Figure 1 The all-terrain vehicle 100 includes a frame 10, body panels 20, a running gear 30, and a power system (not shown). The frame 10 includes a front frame 11, a middle frame 12, and a rear frame 13, which together form a driver's cab 40. The body panels 20 at least partially cover the frame 10, and the running gear 30 is at least partially disposed beneath the frame 10. The power system drives the running gear 30.
[0027] The body panel 20 includes sheet metal and plastic parts, used to cover the frame 10 and protect the all-terrain vehicle 100. The running system 30 includes a plurality of wheels 31, which are rotatably connected to the frame 10. At least one wheel 31 is connected to a power system, which can drive at least one wheel 31 to rotate in order to drive the all-terrain vehicle 100.
[0028] In some embodiments, the all-terrain vehicle 100 is an electrically driven all-terrain vehicle 100. The power system includes a battery compartment and a battery, with the battery compartment located on the rear frame 13 and the battery housed within the battery compartment.
[0029] Understandably, in the electrically driven all-terrain vehicle 100, the power system can be an electric motor.
[0030] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 and Figure 2 The front, rear, left, right, top, and bottom sides are shown. In this embodiment, the front, rear, left, right, top, and bottom directions refer to the directions when the all-terrain vehicle 100 is on a horizontal plane. The front-rear direction refers to the length direction of the all-terrain vehicle 100 provided in this application, the left-right direction refers to the width direction of the all-terrain vehicle 100 provided in this application, and the up-down direction refers to the height direction of the all-terrain vehicle 100 provided in this application.
[0031] In some embodiments, the frame 10 is substantially symmetrical about the left and right when viewed along the length of the all-terrain vehicle 100.
[0032] See Figure 1 and Figure 3 In some embodiments, the rear frame 13 includes an upper support frame 131, a lower support frame 132, and a sheet metal structural member 133. The upper support frame 131, the lower support frame 132, and the sheet metal structural member 133 enclose a accommodating compartment 134, in which the power system is disposed. One end of the upper support frame 131 is connected to the middle frame 12, and the other end extends toward the rear of the all-terrain vehicle 100. The lower support frame 132 is disposed below the upper support frame 131, with one end connected to the middle frame 12 and the other end extending toward the rear of the all-terrain vehicle 100. The sheet metal structural component 133 is located on the rear side of the frame 10. When viewed from the rear of the all-terrain vehicle 100, at least a portion of the sheet metal structural component 133 is visible. One end of the sheet metal structural component 133 is connected to the lower part of the upper support frame 131, and the other end is connected to the upper part of the lower support frame 132. The sheet metal structural component 133 has multiple functional holes 1331.
[0033] The sheet metal structural component 133 can cooperate with the upper support frame 131 and the lower support frame 132 to form a housing compartment 134 for accommodating the power system, allowing for its installation. Functional holes 1331 are provided on the sheet metal structural component 133 to reduce the overall weight of the rear frame 13, and the power system can also dissipate heat through these holes. Located at the rear of the frame 10, the sheet metal structural component 133 not only reinforces the rear load-bearing capacity of the frame 10 but also protects the power system, making it less susceptible to impacts in harsh driving conditions and improving driving safety. Through the application of the multi-functional sheet metal structural component 133, an integrated design of weight reduction, support, and protection is achieved, thereby reducing the weight and manufacturing cost of the all-terrain vehicle 100.
[0034] In some embodiments, the total area of the plurality of functional holes 1331 accounts for 10% to 30% of the area of the sheet metal structural component 133. The area of the functional hole 1331 refers to the size of the space within the functional hole 1331. The arrangement of the plurality of functional holes 1331 allows for weight reduction while maintaining the structural strength of the sheet metal component.
[0035] In some embodiments, when viewed along the front-rear direction of the all-terrain vehicle 100, the power system and the sheet metal structure at least partially overlap, and the functional hole 1331 penetrates the sheet metal structure 133 along the front-rear direction of the all-terrain vehicle 100.
[0036] Along the front-rear direction of the all-terrain vehicle 100, the compartment 134 and the functional hole 1331 can form an airflow channel. During the vehicle formation process, the heat emitted by the power system of the compartment 134 can be discharged through the heat dissipation hole, thereby accelerating the heat dissipation of the power system and improving driving safety.
[0037] In some embodiments, the rear frame 13 includes a tow hook (not shown) detachably suspended from one of the functional holes 1331. The functional hole 1331 can be used as a mating hole for the tow hook, and when the tow hook is suspended from the functional hole 1331, the all-terrain vehicle 100 can be used as a rescue vehicle to facilitate towing and rescue of other vehicles; when the tow hook is not needed, it can be removed from the functional hole 1331.
[0038] Please see Figure 3 In some embodiments, the edge of the functional hole 1331 is provided with a flange (not shown), and the flange protrudes from the surface of the functional hole 1331 by a distance of 0.5 mm to 3 mm. When the trailer hitch engages with the functional hole 1331, the position of the functional hole 1331 is subjected to greater force. By providing a flange at the edge of the functional hole 1331, the structural strength at the position of the functional hole 1331 is improved, making the sheet metal structural component 133 less prone to damage.
[0039] In some embodiments, the shape of the functional hole 1331 may be, but is not limited to, circular, elliptical, square, or irregular. For example, the shape of the functional hole 1331 is similar to the shape of the hole in a bottle opener, the position of the functional hole 1331 can be used as a bottle opener, and the edge of the functional hole 1331 can hook onto the edge of the bottle cap to open the bottle cap.
[0040] Please see Figure 3 In some embodiments, the sheet metal structural member 133 is provided with reinforcing ribs 1332. The reinforcing ribs 1332 are used to improve the bending and torsional resistance of the sheet metal structural member 133 and improve the stability of the all-terrain vehicle 100 in complex terrain.
[0041] In some embodiments, the rear frame 13 includes a locking member (not shown), which connects the sheet metal structural member 133 to the upper support frame 131 and the lower support frame 132 via a functional hole 1331. For example, the locking member includes a bolt and a nut, with the bolt passing through the functional hole 1331. The functional hole 1331 reduces the weight of the frame 10 and serves as a mating hole for the locking member to facilitate connection between the sheet metal structural member 133 and the upper support frame 131 and the lower support frame 132, thus improving the versatility of the functional hole 1331.
[0042] Please see Figure 3 In some embodiments, the sheet metal structural component 133 includes two vertical sheet metal components 1334 and at least one horizontal sheet metal component 1333. The vertical sheet metal components 1334 extend along the vertical direction of the all-terrain vehicle 100, with one end connected to the upper support frame 131 and the other end connected to the lower support frame 132. The two vertical sheet metal components 1334 are disposed on both sides of the all-terrain vehicle 100 in the width direction. The horizontal sheet metal component 1333 extends along the left-right direction of the all-terrain vehicle 100, with one end connected to one of the vertical sheet metal components 1334 and the other end connected to the other vertical sheet metal component 1334.
[0043] Understandably, the connection between the horizontal sheet metal part 1333 and the vertical sheet metal part 1334 can be either welding or bolt connection.
[0044] In some embodiments, the sheet metal structural component 133 is integrally formed.
[0045] Please see Figure 4 In some embodiments, the sheet metal structural member 133 has an arcuate surface 1335 that protrudes toward the power system. For example, the arcuate surface 1335 is provided on the transverse sheet metal member 1333. The arcuate surface 1335 of the sheet metal structural member 133 can guide the airflow from the accommodating compartment 134 toward the rear of the all-terrain vehicle 100, thereby reducing the air resistance experienced by the all-terrain vehicle 100 and improving fuel economy.
[0046] Please see Figure 1 In some embodiments, the all-terrain vehicle 100 includes a rear compartment 50, which is disposed above the upper support frame 131 and, along the vertical direction of the all-terrain vehicle 100, at least a portion of the rear compartment 50 is projected onto the sheet metal structure 133. The rear compartment 50 can apply a portion of its weight to the sheet metal structure 133, thereby enabling the sheet metal structure 133 to support the rear compartment 50 and improving the versatility of the sheet metal structure 133.
[0047] In addition, those skilled in the art may make other changes within this application. Of course, all such changes made in accordance with this application should be included within the scope disclosed in this application.
