Detailed Implementation

[0017] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and embodiments, is provided. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0019] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0020] Please see Figure 1 An all-terrain vehicle 100 includes a frame 11, a body panel 12, a running system 13, a power system 14, a transmission system 15, and a steering system 16. The body panel 12 at least partially covers the frame 11, the running system 13 is at least partially located under the frame 11, the power system 14 is supported by the frame 11 and provides power to the running system 13, the transmission system 15 drivesly connects the power system 14 and the running system 13, and the steering system 16 is located on the frame 11 and connected to a portion of the running system 13.

[0021] To clearly illustrate the technical solution of this application, the terms front, rear, left, right, top, and bottom are defined as shown in the figure. In this application, the length direction of the frame 11 of the all-terrain vehicle 100 refers to the front-rear direction in the figure, the width direction of the frame 11 of the all-terrain vehicle 100 refers to the left-right direction in the figure, and the height direction of the frame 11 of the all-terrain vehicle 100 refers to the up-down direction in the figure. The front, rear, left, right, top, and bottom directions in the figure are based on the state of the all-terrain vehicle 100 traveling on a level road surface, not on the state of traveling on an inclined road surface.

[0022] Please see Figure 1 and Figure 2 The steering system 16 includes a steering column 161, a steering tube 162, and a connecting assembly 163. The steering tube 162 is located above the steering column 161 and is fixedly connected to the steering column 161 via the connecting assembly 163. The steering tube 162 is bent, and its middle portion is fixed above the steering column 161 via the connecting assembly 163, forming a stable mechanical connection between the steering tube 162 and the steering column 161 to ensure effective transmission of steering torque.

[0023] The body panel 12 includes a steering cover 121, which is located below the steering tube 162. The main body of the steering cover 121 is located in front of the steering column 161. The steering cover 121 is connected to the steering column 161, thereby reducing the space occupied by the components above the steering tube 162 and improving the functional expandability of the steering tube area.

[0024] Please see Figure 2 and Figure 3 In some embodiments, the connecting assembly 163 includes a connecting plate 1631, a fixing seat 1632, and a pressure block 1633. The connecting plate 1631 is fixedly installed on the upper end of the steering column 161 by fasteners. The fixing seat 1632 is fixed to the upper surface of the connecting plate 1631 by bolts and is located on the side of the connecting plate 1631 away from the steering column 161. The pressure block 1633 cooperates with the fixing seat 1632, and the two together form a covering clamping structure on the outer circumferential surface of the steering tube 162. Specifically, the inner surfaces of the fixing seat 1632 and the pressure block 1633 are respectively provided with arc-shaped grooves that match the outer contour of the steering tube 162. After being tightened by bolts, they form a circumferential clamping and fixing of the steering tube 162, ensuring the effective transmission of steering torque.

[0025] Please see Figures 3 to 5 In some embodiments, the steering cover 121 includes a front baffle 1211, two side baffles 1212 disposed along the width direction of the frame 11, and a lower baffle 1213 disposed below the front baffle 1211. The front baffle 1211 is located in front of the connecting plate 1631 and below the mounting base 1632. Both side baffles 1212 are connected to the lower baffle 1213 and form a continuous transition connection with the front baffle 1211, forming a semi-open shell structure. The connecting plate 1631 is located between the two side baffles 1212, thereby shielding the connection structure between the connecting plate 1631 and the steering column 161 and the mounting base 1632. This not only improves the overall appearance of the steering area but also mitigates the problem of foreign objects entering the connection structure between the connecting plate 1631 and the steering column 161 and the mounting base 1632.

[0026] In this embodiment, the main body of the steering cover 121 includes a front cover 1211, a side cover 1212, and a front portion of a lower cover 1213.

[0027] In some embodiments, the distance between the upper ends of the two side stops 1212 is greater than the distance between their lower ends. In this embodiment, the distance between the lower portions of the two side stops 1212 gradually decreases from top to bottom. This tapered design, wider at the top and narrower at the bottom, optimizes the space utilization of the steering cover 121. The wider upper internal space facilitates the enclosure of the structure connecting the connecting plate 1631 to the steering column 161, while the gradually narrowing lower internal space gradually conforms to the periphery of the steering column 161, thereby freeing up space for wiring harness arrangement and enhancing the overall structural compactness.

[0028] Please see Figure 2 and Figure 3 In some embodiments, the outer surface of the side shield 1212 is aligned with the side edge of the mounting base 1632 along the width direction of the frame 11, thereby achieving a smooth transition and structural continuity between the steering cover 121 and the mounting base 1632, enhancing the covering effect of the side shield 1212 on the connection structure of the mounting base 1632, and providing more comprehensive protection for the connection between the steering column 161 and the connecting plate 1631. Simultaneously, the edge alignment of the side shield 1212 and the mounting base 1632 also facilitates more effective guidance of external airflow through the side shield 1212, reducing wind resistance noise during driving.

[0029] In some embodiments, the outer surface of the front windshield 1211 is aligned with the front side of the mounting base 1632, thereby achieving a smooth transition and structural continuity between the steering cover 121 and the mounting base 1632, enhancing the covering effect of the front windshield 1211 on the connection structure of the mounting base 1632, and providing more comprehensive protection for the connection part of the steering column 161. Alignment between the front windshield 1211 and the front side of the mounting base 1632 also facilitates more effective guidance of external airflow through the front windshield 1211, reducing wind resistance noise during driving.

[0030] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the lower stop 1213 is provided with a groove 1213a recessed toward the front stop 1211, and the steering column 161 is engaged in the groove 1213a, which helps to simplify the assembly process. The snap-fit ​​method replaces the traditional bolt fixing, reducing the number of installation steps and parts, and improving assembly efficiency.

[0031] In some embodiments, a reinforcing plate 1611 is provided around the steering column 161, and the reinforcing plate 1611 is fixedly connected to the steering column 161 and the connecting plate 1631. By increasing the connection structure between the steering column 161 and the connecting plate 1631, the stress generated during steering operation is effectively dispersed, and the risk of loosening of the connection parts due to vibration or impact is reduced.

[0032] In some embodiments, the surface of the reinforcing plate 1611 is shaped like an isosceles trapezoid, with its two isosceles sides welded and fixed to the bottom surface of the connecting plate 1631 and the outer peripheral surface of the steering column 161, respectively. The welded isosceles sides increase the contact area, making the load distribution more uniform and reducing the risk of weld cracking. At the same time, the geometric stability of the isosceles trapezoid enhances the overall resistance to deformation, and the welded isosceles sides directly fit against the steering column 161 and the connecting plate 1631, further improving the rigidity and durability of the connection.

[0033] In some embodiments, two reinforcing plates 1611 are provided, symmetrically arranged on the outer peripheral surface of the steering column 161. The two reinforcing plates 1611 are fixedly connected to the outer peripheral surface of the steering column 161 by welding, and the tops of both reinforcing plates 1611 are welded to the bottom surface of the connecting plate 1631. This structural design of symmetrically arranged double reinforcing plates 1611, by forming a stable triangular support structure, significantly improves the connection strength and overall rigidity between the steering column 161 and the connecting plate 1631.

[0034] In some embodiments, the reinforcing plate 1611 is located behind the front stop 1211, and the surface of the front stop 1211 facing the reinforcing plate 1611 is provided with a connecting post 1211a. The end face of the connecting post 1211a away from the front stop 1211 abuts against the reinforcing plate 1611. The connecting assembly 163 includes a connector 1634, which passes through the reinforcing plate 1611 and is fixedly connected to the connecting post 1211a to fix the relative position of the connecting post 1211a and the reinforcing plate 1611.

[0035] In some embodiments, the connector 1634 is a self-tapping screw. In other embodiments, the connector 1634 is a bolt, and the connecting post 1211a has a nut that mates with the bolt.

[0036] In some embodiments, the connecting assembly 163 includes a plurality of fasteners 1635, which pass through the pressure block 1633 and the fixing seat 1632 and are fixedly connected to the connecting plate 1631 to fix the relative positions of the pressure block 1633, the fixing seat 1632, and the connecting plate 1631. In this embodiment, four fasteners 1635 are provided, respectively located at the four corners of the pressure block 1633.

[0037] In some embodiments, the fastener 1635 includes a protrusion 1635a that partially protrudes from the connecting plate 1631 in a direction away from the fixing seat 1632. The front stop 1211 has a limiting plate 1214 on its inner wall facing the steering column 161. The limiting plate 1214 has a limiting hole 1214a that extends substantially in the vertical direction. The protrusion 1635a engages with the limiting hole 1214a. This engaging structure simplifies the assembly process, replaces traditional bolt fixing with mechanical interlocking, reduces the number of parts, and the fit clearance between the protrusion 1635a and the limiting hole 1214a can absorb some assembly tolerances, improving system adaptability.

[0038] The limiting hole 1214a engages with the protrusion 1635a that is closer to the front stop 1211.

[0039] In some embodiments, two limiting plates 1214 are provided, which are located on both sides of the inner surface of the front baffle 1211 and are connected to the corresponding side baffles 1212, thereby improving the connection stability between the steering cover 121 and the reinforcing plate 1611.

[0040] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
