[0033] This embodiment discloses a vehicle, which includes a vehicle body, a plurality of wheels, shock absorbers, swing arms, and connection components. The plurality of wheels are respectively connected to the vehicle body. The upper end of the shock absorber is connected to the vehicle body through a top support, and the lower end of the shock absorber is connected to the swing arm through the connection component. The shock absorber is used to reduce the vibration generated during the driving of the vehicle through the damping effect inside it, so as to provide a smooth riding experience for passengers. The swing arm is connected to the vehicle body and is used to support the vehicle body and the shock absorber, so as to provide a smoother riding experience for passengers.

[0034] Refer to Figure 1 and Figure 2 as shown in Figure 1 is a cross-sectional view of the connection component provided by the embodiment of the present application, Figure 2 is a cross-sectional view of the side view of the connection component provided by the embodiment of the present application. The connection component includes a casting 1, a connection bushing 2, a fastening component 3, and a sliding bushing 4. The casting 1 is connected to the swing arm, and the casting 1 is provided with a receiving portion 11. The connection bushing 2 is connected to the shock absorber. The connection bushing 2 is disposed in the receiving portion 11, and one end of the connection bushing 2 abuts against the inner wall of the receiving portion 11. The fastening component 3 passes through the casting 1 and the connection bushing 2 respectively and is used to connect the casting 1 and the connection bushing 2. The sliding bushing 4 is sleeved on the fastening component 3 and is located between the casting 1 and the fastening component 3, and the sliding bushing 4 abuts against the other end of the connection bushing 2 to tightly press the connection bushing 2 against the inner wall of the casting 1 through the sliding bushing 4. The sliding bushing 4 is provided with a limiting portion 41, and the casting 1 is provided with a limiting and mating portion 12. The limiting portion 41 cooperates with the limiting and mating portion 12 to limit the relative rotation between the sliding bushing 4 and the casting 1.

[0035] The sliding liner 4 of this embodiment is provided with a limiting portion 41, and the casting 1 is provided with a limiting and mating portion 12. The limiting portion 41 cooperates with the limiting and mating portion 12 to limit the relative rotation between the sliding liner 4 and the casting 1. By limiting the sliding liner 4 and the casting 1 in the rotational direction, the situation of looseness between the vehicle connection structures caused by torque attenuation is reduced, ensuring the stability and reliability of the vehicle connection structures, and thus ensuring the normal operation of the vehicle.

[0036] Refer to Figure 2 As shown, the limiting portion 41 is set as a first limiting plane 410, and the limiting and mating portion 12 is set as a second limiting plane 120. The first limiting plane 410 and the second limiting plane 120 are simple to machine and convenient to manufacture. The first limiting plane 410 fits with the second limiting plane 120 to limit the relative rotation between the sliding liner 4 and the casting 1 through the first limiting plane 410 and the second limiting plane 120.

[0037] In this embodiment, the first limiting plane 410 is provided with a plurality of first grooves, and the second limiting plane 120 is provided with a plurality of second grooves, which increases the friction between the first limiting plane 410 and the second limiting plane 120, thereby further strengthening the limitation of the relative rotation between the sliding liner 4 and the casting 1, further reducing the situation of looseness between the vehicle connection structures caused by torque attenuation, and ensuring the normal operation of the vehicle. It can be understood that in other embodiments, only the first limiting plane 410 may be provided with a plurality of first grooves, or only the second limiting plane 120 may be provided with a plurality of second grooves.

[0038] Refer to Figure 2 As shown, there are a plurality of limiting portions 41, and the plurality of limiting portions 41 are respectively distributed at intervals along the circumferential direction of the sliding liner 4. There are a plurality of limiting and mating portions 12, and the positions of the respective limiting and mating portions 12 are respectively set corresponding to the positions of the respective limiting portions 41. By providing a plurality of limiting portions 41 and a plurality of limiting and mating portions 12, the limitation of the relative rotation between the sliding liner 4 and the casting 1 is strengthened, and the situation of torque attenuation generated between the sliding liner 4 and the casting 1 is further reduced, thereby further improving the stability and reliability of the vehicle connection structure.

[0039] In this embodiment, there are two limiting portions 41, and the two limiting portions 41 are respectively located at opposite ends of the sliding liner 4, so that when the limiting portion 41 cooperates with the limiting and mating portion 12 for limiting, the sliding liner 4 and the casting 1 can be uniformly restricted by the rotational force. It can be understood that in other embodiments, there may also be only one, or three, or more than three limiting portions 41.

[0040] In some embodiments, the limiting part 41 is configured as a limiting protrusion, and the limiting cooperation part 12 is configured as a limiting groove. The limiting protrusion is disposed within the limiting groove to limit the limiting protrusion in the rotational direction through the inner wall of the limiting groove. Among them, the shape of the limiting protrusion corresponds to the shape of the limiting groove to reduce the gap between the limiting protrusion and the limiting groove, thereby further strengthening the restriction on the relative rotation between the sliding liner 4 and the casting 1. The cross-sectional shape of the limiting protrusion can be triangular, square, etc.

[0041] In this embodiment, the limiting part 41 is configured as a limiting protrusion, and the limiting cooperation part 12 is configured as a limiting groove. It can be understood that in other embodiments, the limiting part 41 can also be configured as a limiting groove, and the limiting cooperation part 12 can be configured as a limiting protrusion.

[0042] In this embodiment, the limiting protrusion is provided with a first arc surface, and the limiting groove is provided with a second arc surface. The first arc surface is attached to the second arc surface to limit the relative rotation between the sliding liner 4 and the casting 1. Since there are no sharp edges on the first arc surface and the second arc surface, the wear when the limiting protrusion abuts against the limiting groove can be reduced through the first arc surface and the second arc surface, thereby increasing the service life of the sliding liner 4 and the casting 1 and reducing the cost.

[0043] Refer to Figure 1 As shown, a first connection hole 13 and a second connection hole 14 are respectively provided at both ends of the casting 1. The fastening assembly 3 includes a bolt 31 and a nut 32. The bolt 31 sequentially passes through the first connection hole 13, the connection bushing 2, and the second connection hole 14. The sliding liner 4 is disposed at the second connection hole 14. The nut 32 is connected to the bolt 31 and abuts against the sliding liner 4 to tightly connect the casting 1, the connection bushing 2, and the sliding liner 4.

[0044] A first abutting surface 42 is provided on one side of the sliding liner 4 facing the nut 32, and a second abutting surface 320 is provided on one side of the nut 32 facing the sliding liner 4. When the area of the second abutting surface 320 is greater than or equal to the area of the first abutting surface 42, along the axial direction of the sliding liner 4, the length of the sliding liner 4 is greater than the length of the second connection hole 14, that is, the sliding liner 4 protrudes from the second connection hole 14 to reduce the situation where the nut 32 directly abuts against the casting 1 and cannot limit the casting 1, the connection bushing 2, and the sliding liner 4 axially, thereby ensuring the stability of the connection of the casting 1, the connection bushing 2, and the sliding liner 4. When the area of the second abutting surface 320 is smaller than the area of the first abutting surface 42, along the axial direction of the sliding liner 4, since the nut 32 can directly abut against the sliding liner 4, the length of the sliding liner 4 can be smaller than the length of the second connection hole 14 to reduce the cost.

[0045] In this embodiment, the fastening assembly 3 is a bolt 31 and a nut 32. The connection structure of the bolt 31 and the nut 32 is stable, ensuring the reliability and safety of the connection of the casting 1, the connecting bushing 2, and the sliding liner 4. It can be understood that in other embodiments, the fastening assembly 3 can also be other structures, such as a pin structure or a snap structure, etc.

[0046] Referring to Figure 1 As shown, the connecting bushing 2 includes an inner insertion tube 21, a rubber member 22, an inner skeleton 23, and an outer insertion tube 24. The inner insertion tube 21 is sleeved on the fastening assembly 3, and one end of the inner insertion tube 21 abuts against the inner wall of the accommodating portion 11, and the other end of the inner insertion tube 21 abuts against the sliding liner 4. The inner insertion tube 21 serves as the internal support structure of the connecting bushing 2 and is usually made of a metal material, such as steel or aluminum, for providing necessary strength and rigidity. The rubber member 22 is sleeved on the inner insertion tube 21 and functions to buffer and dampen vibrations. The rubber member 22 covers the inner skeleton 23, that is, the inner skeleton 23 is embedded in the rubber member 22. The inner skeleton 23 is used to increase the structural strength and stability of the connecting bushing 2, and the inner skeleton 23 can be made of metal or other rigid materials. The outer insertion tube 24 is sleeved on the rubber member 22, and the hanger earring of the shock absorber is sleeved on the outer insertion tube 24. The shock absorber can make relative movement with the swing arm through the torsion and yaw of the connecting bushing 2.

[0047] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
