Description

Technical Field

[0001] The present invention belongs to the technical field of vehicles, and particularly relates to a vehicle seat belt connection assembly and a vehicle. Background Art

[0002] A vehicle seat belt is connected to a corresponding positioning member (such as a suspension rivet) on the vehicle body through a seat belt connection assembly, and is usually connected to a seat through a pluggable movable buckle to provide safety protection for the driver and passengers. The seat belt connection assembly generally connects the seat belt and the positioning member and can rotate around the positioning member. Generally, the seat belt connection assembly is provided with an elastic member to abut against the positioning member. In the actual use process, the action of pulling the seat belt occurs repeatedly, and the seat belt connection assembly rotates around the positioning member frequently. The elastic abutment of the elastic member against the positioning member causes frictional resistance to the rotation of the elastic member, and the fixed position of the elastic member needs to be stressed to overcome the above frictional resistance. Over time, the fixed connection will be damaged, resulting in connection failure, and then the seat belt connection assembly will be disengaged from the positioning member, causing the seat belt to lose its corresponding safety protection function. Summary of the Invention

[0003] In view of the above technical problems, the present invention provides a vehicle seat belt connection assembly and a vehicle. The vehicle seat belt connection assembly can effectively reduce the risk of connection failure at the fixed connection of the elastic piece, and prevent the seat belt connection assembly from being disengaged from the positioning member.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0024] It should be noted that if there are directional indications involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0025] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] In view of the risk of connection failure of the elastic member that abuts against the positioning member in the existing vehicle seat belt connection assembly. The vehicle seat belt connection assembly of the present invention aims to solve the above technical problems, and also proposes a vehicle including the vehicle seat belt connection assembly of the present invention.

[0027] Figures 1 to 3 Exemplarily shown is a vehicle seat belt connection assembly I according to the present invention (hereinafter referred to as connection assembly I), which includes a connection plate 10 and an elastic piece 20. The connection plate 10 has a seat belt hole 11 and a connection hole 12, and can be connected to a vehicle seat belt 40 (hereinafter referred to as seat belt 40) through the seat belt hole 11, and can be connected to a corresponding positioning member 30 on the vehicle body through the connection hole 12 and can rotate around the positioning member 30. The elastic piece 20 is fixedly arranged (such as riveting or welding) on the connection plate 10 and can limit and hold the positioning member 30 in the connection hole 12. By elastically abutting against the positioning member 30, the disconnection of the connection plate 10 from the positioning member 30 is prevented, such as Figure 4 and Figure 5 shown. A limiting portion 13 is provided on the connection plate 10. The limiting portion 13 is configured to limit the rotation of the elastic piece 20 relative to the connection plate 10 during the rotation of the connection plate 10 relative to the positioning member 30, especially to limit the rotation of the elastic piece 20 relative to the connection plate 10 in the rotation direction of the connection plate 10. During the process of the seat belt 40 pulling the connection plate 10 and the elastic piece 20 to rotate around the positioning member 30, the connection plate 10 applies / transmits force to the elastic piece 20 through the limiting portion 13 and the fixed connection (such as riveting or welding) between the connection plate 10 and the elastic piece 20 to rotate against the friction force between the positioning member 30 and the elastic piece 20, that is, the limiting portion 13 can drive / promote the elastic piece 20 to rotate synchronously with the connection plate 10 around the positioning member 30, thereby limiting the rotation of the elastic piece 20 relative to the connection plate 10. In this way, the limiting portion 13 at least partially shares the force applied by the connection plate 10 to the elastic piece 20, reduces the force on the fixed connection (such as riveting or welding) between the connection plate 10 and the elastic piece 20, and thus reduces the risk of disconnection (rivet 23 loosening or weld breakage). A vehicle including this connection assembly I also has a positioning member 30, and the positioning member 30 is connected to the connection assembly I in the above manner. Preferably, the positioning member 30 can be configured as a suspension rivet, such as Figure 4 and Figure 5 shown.

[0028] In some embodiments, as Figures 1 to 5 shown, the elastic piece 20 includes a mounting section 21 and an elastic section 22. The mounting section 21 is fixedly riveted or welded to the connection plate 10. The elastic section 22 extends from the mounting section 21 by bending and is configured to face away from the connection plate 10 when fixed to the connection plate 10. Advantageously, the limiting portion 13 is arranged adjacent to the mounting section 21 to limit the rotation of the mounting section 21 of the elastic piece 20 relative to the connection plate 10 during the rotation of the connection plate 10 relative to the positioning member 30, effectively relieving the force at the fixed connection of the elastic piece 20, and the elastic section 22 can hold the positioning member 30 in the connection hole 12.

[0029] In some embodiments, the mounting section 21 includes a limiting arm 21A, and the limiting portion 13 is configured to be adjacent to the limiting arm 21A. It should be understood that the limiting portion 13 can be any suitable structure arranged on the connecting plate 10, such as the limiting portion 13 can be a block or a protrusion arranged on the connecting plate 10. Preferably, a flange is provided along the edge of the safety belt hole 11 as the limiting portion 13, and the flange is adjacent to the limiting arm 21A to limit the limiting arm 21A, thereby limiting the rotation of the elastic sheet 20 relative to the connecting plate 10 during the rotation of the connecting plate 10 relative to the positioning member 30. The flange can be formed integrally with the connecting plate 10 and the safety belt hole 11 in a single stamping process, thereby substantially not increasing the manufacturing cost. At the same time, it should be understood that the setting of the flange can increase the contact area between the safety belt hole 11 and the safety belt 40, thereby dispersing the force applied to the safety belt 40, which is conducive to preventing the wear of the safety belt 40.

[0030] It should be understood that the shape of the limiting arm 21A can be configured to correspond to the contour of the limiting portion 13, such as Figure 1 and Figure 2 As shown, the safety belt hole 11 is configured as an oblong hole and has an arc-shaped edge 11A. At the arc-shaped edge 11A, the contour of the stopper 13 / flange is also in an arc-shaped shape. The shape of the stopper arm 21A adapts to the contour shape of the stopper 13 to abut against the stopper 13, for example, the substantially U-shaped arm shape shown in the figure partially corresponds to the contour shape of the stopper 13. Optionally, in some embodiments, the stopper arm may also completely correspond to the contour shape of the stopper 13. At the same time, it should be understood that the safety belt hole 11 is configured as an oblong hole to reduce the wear on the safety belt 40.

[0031] In some embodiments, Figure 2 As shown, the connecting hole 12 is constructed as an elongated hole and includes a fixing section 12A, a guide section 12B and a connecting section 12C. The guide section 12B is larger than the fixing section 12A and is connected to the fixing section 12A through the connecting section 12C. The following description will be made by taking the case where the positioning member 30 is configured as a suspension rivet. Figure 4 and Figure 5 As shown, the suspension rivet includes a rivet head 31 with a larger diameter and a rivet shank 32 with a smaller diameter. The connecting hole 12 can cover the rivet head 31 and the rivet shank 32 of the suspension rivet through its guide section 12B, and then the rivet shank 32 slides into the fixing section 12A through the connecting section 12C. The size of the fixing section 12A is smaller than the diameter of the rivet head 31, so the rivet head 31 cannot be detached from the fixing section 12A along its axial direction.

[0032] In certain further embodiments, Figures 1 to 5As shown, the elastic section 22 of the elastic sheet 20 includes a holding arm 22A formed by bending and extending at a first angle α. The holding arm 22A extends away from the mounting section 21 and bends towards the connecting plate 10 when the mounting section 21 is fixed to the connecting plate 10. During the process of the positioning member 30 configured as a suspension rivet sliding into the fixing section 12A, the positioning member 30 will push up the holding arm 22A to cause elastic deformation. When the positioning member 30 enters the fixing section 12A, the holding arm 22A elastically recovers and can abut against the circumferential side of the rivet head 31 of the positioning member 30 located in the fixing section 12A, limiting and holding the positioning member 30 in the fixing section 12A / connecting hole 12 in its radial direction, preventing the positioning member 30 from moving from the fixing section 12A to the guiding section 12B and then sliding out of the connecting hole 12. It should be understood that this setting method facilitates the assembly and connection of the connection assembly I to the positioning member 30 configured as a suspension rivet.

[0033] Preferably, the elastic section 22 of the elastic sheet 20 further includes a crimping arm 22B formed by bending and extending at a second angle β. The crimping arm 22B extends away from the mounting section 21 and bends towards the connecting plate 10 when the mounting section 21 is fixed to the connecting plate 10. In the connection assembly I, the crimping arm 22B can extend to elastically abut against the connecting plate 10. When the positioning member 30 configured as a suspension rivet enters the fixing section 12A, the rivet head 31 of the suspension rivet will push up the crimping arm 22B and be elastically held by the crimping arm 22B on the connecting plate 10. The rivet head 31 is located between the connecting plate 10 and the crimping arm 22B, as Figure 4 and Figure 5 shown, thereby avoiding abnormal noise caused by collision due to relative movement between the connection assembly I and the positioning member 30 along the axial direction of the positioning member.

[0034] It should be understood that the holding arm 22A and the crimping arm 22B can have different bending angles. For example, compared to the plane substantially parallel to the connecting plate 10, the first angle α at which the holding arm 22A bends and extends can be greater than the second angle β at which the crimping arm 22B bends and extends, as Figure 3 and Figure 5 shown. Preferably, as Figure 1 and Figure 2 shown, the holding arm 22A can be formed during the stamping process of the crimping arm 22B, for example, the holding arm 22A is integrally stamped on the crimping arm 22B.

[0035] It should be understood that both the connecting plate 10 and the elastic sheet 20 can be sheet metal parts. On the connecting plate 10, the seat belt hole 11 and the connecting hole 12 can have any suitable mutual arrangement relationship. As Figure 2As shown, when both the seat belt hole 11 and the connection hole 12 are configured as elongated holes, their extension directions can be substantially perpendicular to each other. Moreover, the connection hole 12 is substantially aligned with the middle position of the extension direction of the seat belt hole 11, and the fixed installation position of the elastic piece 20 on the connection plate 10 is between the seat belt hole 11 and the connection hole 12. Regardless of the arrangement method, according to the concept of the present invention, the position of the limiting portion can be correspondingly set to limit the elastic piece, so as to effectively prevent the loosening of the connection between the elastic piece and the connection plate.

[0036] It should be understood that the above description of the preferred embodiment is relatively detailed, and it should not be considered as a limitation of the protection scope of the present invention patent. Under the inspiration of the present invention, those of ordinary skill in the art can also make substitutions or deformations without departing from the protection scope defined by the claims of the present invention, and all fall within the protection scope of the present invention. The scope of protection claimed by the present invention shall be subject to the appended claims.
