[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0029] Figure 1A vehicle 100 is shown, which includes a frame 11, a traveling assembly 12, a power assembly 13, a suspension assembly 14 and a transmission assembly 15. The frame 11 serves as the basic framework of the vehicle 100 and is used to support the traveling assembly 12, the power assembly 13, the suspension assembly 14 and the transmission assembly 15. The suspension assembly 14 is used to connect the traveling assembly 12 to the frame 11, so that the traveling assembly 12 can be connected to the frame 11. The power assembly 13 is at least partially connected to the traveling assembly 12 for transmission. Specifically, the power assembly 13 is connected to the traveling assembly 12 through the transmission assembly 15, so that the power assembly 13 can drive the traveling assembly 12 to move, thereby realizing the movement of the vehicle 100.

[0030] It should be noted that the vehicle 100 may be Figure 1 The all-terrain vehicle shown is a vehicle 100 , but the vehicle 100 may also be a motorcycle or other vehicle having a traveling component 12 .

[0031] In order to clearly explain the technical solution of this application, the following is also defined: Figure 1 In the present application, the length direction of the vehicle 100 refers to the front, rear, left, right, top and bottom. Figure 1 The front-to-rear direction in the vehicle 100 refers to the width direction of the vehicle 100. Figure 1 The left and right directions in the figure, the height direction of the vehicle 100 refers to Figure 1 Specifically, the traveling assembly 12 is at least partially connected to the lower side of the vehicle frame 11.

[0032] like Figure 2 and Figure 3 As shown, the vehicle 100 includes a bolt 16, a nut 17 and a mounting assembly 18, and the mounting assembly 18 is any two parts on the vehicle 100 connected by the bolt 16 and the nut 17. Specifically, the mounting assembly 18 includes a first connecting member 181 and a second connecting member 182 connected by the bolt 16 and the nut 17.

[0033] As an implementation method, a connecting hole 1811 is provided on the first connecting member 181, and the bolt 16 passes through the second connecting member 182 and the connecting hole 1811 and is connected to the nut 17. During the driving process of the vehicle 100, the nut 17 and the connecting hole 1811 cooperate with each other to bear force. Since the first connecting member 181 is easily deformed due to the force, the vibration impact during the driving process of the vehicle 100 will cause the nut 17 and the connecting hole 1811 to shift, thereby reducing the contact area between the nut 17 and the connecting hole 1811, causing the nut 17 to eventually loosen. In addition, when the locking torque of the nut 17 is too large, it is easy to crush the surface of the first connecting member 181 at the connecting hole 1811, thereby causing the first connecting member 181 to wear or even be scrapped, and reducing the utilization rate of the first connecting member 181.

[0034] To avoid the above situation, the vehicle 100 of the present application further includes a mounting bushing 183, which is located in the connection hole 1811. The bolt 16 passes through the second connection member 182 and the mounting bushing 183 and is connected to the nut 17. The bolt 16 is basically a cylindrical structure.

[0035] like Figure 3 and Figure 4 As shown, specifically, the mounting bushing 183 includes a first abutment portion 1831, and along the radial direction of the bolt 16, the first abutment portion 1831 is located between the inner wall of the connecting hole 1811 and the bolt 16, and the first abutment portion 1831 abuts against the inner wall of the connecting hole 1811 and the bolt 16 respectively. The inner wall surface of the first abutment portion 1831 is a conical surface. The nut 17 is a conical nut.

[0036] Through the above-mentioned arrangement, the bolt 16 and the connecting hole 1811 can be connected by being pressed by the installing bushing 183. When vibration impact is generated during the driving of the vehicle 100, the installing bushing 183 can not only protect the surface of the first connecting member 181 at the connecting hole 1811 from being worn, but also the deformation of the nut 17 and the connecting hole 1811 caused by the vibration impact can be reduced by installing the bushing 183. That is, the existence of the installing bushing 183 can slow down the vibration impact between the nut 17 and the connecting hole 1811, thereby reducing the probability of the nut 17 loosening, thereby increasing the service life of the first connecting member 181 and improving the connection stability between the first connecting member 181 and the second connecting member 182.

[0037] In this embodiment, the first abutting portion 1831 at least partially extends away from the first abutting portion 1831 to form a fitting portion 1832, and the fitting portion 1832 abuts against the inner wall of the connecting hole 1811. Through the above arrangement, the fitting portion 1832 can press the mounting bushing 183 and the connecting hole 1811 tightly. When the mounting bushing 183 abuts against the connecting hole 1811, when vibration and impact are generated during the driving of the vehicle 100, the fitting portion 1832 can reduce the wear between the mounting bushing 183 and the connecting hole 1811, thereby improving the service life of the first connecting member 181 and the mounting bushing 183, and improving the connection stability between the first connecting member 181 and the second connecting member 182.

[0038] As an implementation method, the mounting bushing 183 also includes a second abutment portion 1833, which is integrally formed with the first abutment portion 1831. The first abutment portion 1831 is basically a hollow cylindrical structure, and the second abutment portion 1833 is basically a hollow truncated cone structure; the inner diameter of the end of the second abutment portion 1833 close to the first abutment portion 1831 is the first diameter, and the inner diameter of the end of the second abutment portion 1833 away from the first abutment portion 1831 is the second diameter, and the first diameter is smaller than the second diameter; the inner diameter of the first abutment portion 1831 is the third diameter, and the first diameter and the third diameter are basically the same. Through the above arrangement, the bolt 16 can be connected to the nut 17 after passing through the mounting bracket, the first abutment portion 1831 and the second abutment portion 1833.

[0039] Specifically, the second abutting portion 1833 is located between the nut 17 and the inner wall of the connecting hole 1811, and the second abutting portion 1833 abuts against the inner wall of the nut 17 and the connecting hole 1811. Through the above arrangement, the gap between the nut 17 and the connecting hole 1811 can be filled by the second abutting portion 1833, and the nut 17 and the connecting hole 1811 can be prevented from directly contacting by the second abutting portion 1833, that is, the second abutting portion 1833 can mitigate the vibration impact between the nut 17 and the connecting hole 1811, thereby reducing the probability of the nut 17 being loosened, and further improving the connection stability between the first connecting member 181 and the second connecting member 182.

[0040] It should be noted that, in order to make the first abutting portion 1831 abut against the inner wall of the connecting hole 1811 and the bolt 16, and the second abutting portion 1833 abut against the nut 17 and the inner wall of the connecting hole 1811, the inner contour of the connecting hole 1811 is substantially consistent with the outer contour of the mounting bushing 183. In the present application, the connecting hole 1811 can be regarded as a hole formed by connecting a circular through hole and a funnel-shaped through hole. Through the above arrangement, the mounting bushing 183 can be made to fit the inner wall of the connecting hole 1811, the bolt 16 and the nut 17, thereby improving the abutment stability between the mounting bushing 183 and the connecting hole 1811, the bolt 16 and the nut 17.

[0041] like Figure 3 and Figure 5 As shown, illustratively, in the present application, the nut 17 can be set as a conical nut, and the contact surface between the nut 17 and the second abutting portion 1833 is defined as the abutting surface 101, and the angle between the abutting surface 101 and the axis of the bolt 16 is an acute angle. That is, the abutting surface 101 is an inclined surface. It can be understood that the contact surface between the second abutting portion 1833 and the inner wall of the connecting hole 1811 is also set as an inclined surface, so that the abutment between the nut 17, the second abutting portion 1833 and the inner wall of the connecting hole 1811 is more stable, thereby improving the connection stability between the first connecting member 181 and the second connecting member 182.

[0042] As an implementation, the bolt 16 includes a head 161, a columnar portion 162 and an exposed portion 163, which are integrally formed, and the head 161 is located between the columnar portion 162 and the exposed portion 163. The head 161, the columnar portion 162 and the exposed portion 163 are all substantially cylindrical.

[0043] Specifically, the columnar portion 162 passes through the second connector 182 and the mounting bushing 183 and is connected to the nut 17, and the columnar portion 162 abuts against the first abutting portion 1831. Exemplarily, an end of the columnar portion 162 away from the head 161 is formed with an external thread, so that the columnar portion 162 and the nut 17 are threadedly connected.

[0044] Specifically, the second connecting member 182 is provided with a mounting hole 1821, which is coaxially arranged with the connecting hole 1811, and the diameters of the mounting hole 1821 and the connecting hole 1811 are substantially the same. The bolt 16 passes through the mounting hole 1821, is installed with the bushing 183, and is connected with the nut 17. Furthermore, the columnar portion 162 passes through the mounting hole 1821, is installed with the bushing 183, and is connected with the nut 17.

[0045] After the second connector 182 is connected to the first connector 181, the head 161 is at least partially located in the mounting hole 1821, the columnar portion 162 is at least partially located in the connecting hole 1811, and the diameter of the head 161 is greater than the diameter of the columnar portion 162, so that there is an installation gap 102 between the columnar portion 162 and the inner wall of the connecting hole 1811. Since the installation gap 102 makes it impossible for the columnar portion 162 to form contact with the connecting hole 1811, when the nut 17 is loosened due to vibration impact, the bolt 16 and the connecting hole 1811 will shake, thereby increasing the probability of the nut 17 being loosened. Therefore, in the present application, the first abutting portion 1831 is located in the installation gap 102, so as to prevent the bolt 16 from shaking with the connecting hole 1811, thereby reducing the probability of the nut 17 being loosened, and improving the connection stability between the first connector 181 and the second connector 182.

[0046] Specifically, the diameter of the exposed portion 163 is larger than the diameter of the head 161, and the exposed portion 163 abuts against the side of the connecting hole 1811 away from the nut 17. The exposed portion 163 is not arranged in the connecting hole 1811, so that the bolt 16 can fix the first connecting member 181 and the second connecting member 182 through the exposed portion 163 and the nut 17.

[0047] like Figure 6As shown, as an optional implementation, the interlocking portion 1832 is a thread rolling structure. Specifically, the outer surface of the first abutting portion 1831 is formed with an interlocking portion 1832. More specifically, the outer surface of the first abutting portion 1831 protrudes along the radial direction of the bolt 16 to form a plurality of protruding structures 1832a, and the plurality of protruding structures 1832a are basically arranged around the axis of the mounting bushing 183, so that the plurality of protruding structures 1832a form the interlocking portion 1832. In the present application, the protruding structure 1832a basically extends along the axis of the bolt 16. It should be noted that the number of protruding structures 1832a can be adjusted according to actual needs to meet the connection requirements between different first connectors 181 and second connectors 182.

[0048] For example, in the present application, the mounting bushing 183 is a steel part. Since the deformation amount of the steel part caused by the vibration impact is small, through the above configuration, the deformation amount of the nut 17 and the connecting hole 1811 caused by the vibration impact can be small through the mounting bushing 183, that is, the presence of the mounting bushing 183 can reduce the vibration impact between the nut 17 and the connecting hole 1811, thereby reducing the probability of the nut 17 loosening, thereby increasing the service life of the first connecting member 181, and improving the connection stability between the first connecting member 181 and the second connecting member 182.

[0049] As another implementation method, the mounting bushing 183 of the present application can also be set at the connection between the remaining components, and it is only necessary that the connection between the two components is connected by bolts 16 and nuts 17.

[0050] like Figure 7 As shown, the walking assembly 12 includes a rim 121 and a wheel 122 mounted on the rim 121 (see Figure 1 The suspension assembly 14 includes a mounting frame 141, and the mounting frame 141 and the rim 121 are connected by bolts 16 and nuts 17, so that the wheel 122 can be connected to the mounting frame 141 through the rim 121. The first connecting member 181 of the present application can be the rim 121, and the second connecting member 182 can be the mounting frame 141.

[0051] Since the rim 121 is generally made of aluminum, it is easy to deform due to force, which will cause the vibration impact during the driving of the vehicle 100 to cause the nut 17 and the rim 121 to shift, thereby reducing the contact area between the nut 17 and the rim 121, causing the nut 17 to eventually loosen. In addition, when the tightening torque of the nut 17 is too large, it is easy to crush the surface of the rim 121, causing the rim 121 to wear or even be scrapped, and reducing the utilization rate of the rim 121.

[0052] Through the arrangement of the present application, the bolt 16 and the rim 121 can be connected by being pressed by the installation bushing 183. When vibration impact is generated during the driving of the vehicle 100, the installation bushing 183 can not only protect the surface of the rim 121 from wear, but also reduce the deformation of the nut 17 and the rim 121 due to the vibration impact through the installation bushing 183. That is, the presence of the installation bushing 183 can slow down the vibration impact between the nut 17 and the rim 121, thereby reducing the probability of the nut 17 loosening, thereby increasing the service life of the rim 121, and improving the connection stability between the rim 121 and the mounting frame 141.

[0053] Exemplarily, the power assembly 13 includes an engine, and there are several parts on the engine connected by bolts 16 and nuts 17. The two parts on the engine are defined as the first part and the second part. In this case, the first part is the first connecting member 181, and the second part is the second connecting member 182. The first part and the second part are connected by bolts 16 and nuts 17. Specifically, the mounting bushing 183 can be located in the first part, and the bolt 16 passes through the second part, the mounting bushing 183, and is connected to the nut 17. Among them, the nut 17 is a conical nut, so that the mounting bushing 183 can fit the bolt 16 and the nut 17, thereby improving the connection stability of the first part and the second part. Through the above arrangement, when vibration impact is generated during the driving of the vehicle 100, the installation bushing 183 can not only protect the surface of the first component from being worn, but also reduce the deformation of the nut 17 and the first component due to the vibration impact by installing the bushing 183, that is, the existence of the installation bushing 183 can reduce the vibration impact between the nut 17 and the first component, thereby reducing the probability of the nut 17 loosening, thereby increasing the service life of the first component and improving the connection stability between the first component and the second component.

[0054] As an optional implementation, the transmission assembly 15 includes a front axle mechanism, which is a device for transmitting the directional forces between the frame 11 and the wheel 122 and the bending moment and torque generated therefrom. The front axle mechanism also has a number of parts connected by bolts 16 and nuts 17. Therefore, the mounting bushing 183 can also be provided on the front axle mechanism. That is, the first connecting member 181 and the second connecting member 182 are any two parts on the front axle mechanism connected by bolts and nuts.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
