[0028] Please also read Figures 1 to 6 The seat belt guide ring installation assembly and the vehicle provided by the utility model are now described. The seat belt guide ring installation assembly includes a guide ring installation plate 1, a guide ring body 2 and a connecting member 3. The guide ring installation plate 1 is connected to the inner side of the rear side window inner plate 6. The guide ring installation plate 1 has an inner boss 4 protruding toward the inner side of the vehicle body. The guide ring body 2 is connected to the inner boss 4 near the central axis of the vehicle body through the connecting member 3.

[0029] Compared with the prior art, the seat belt guide ring installation assembly provided in the present embodiment has a guide ring installation plate 1 arranged on the side of the rear side window inner panel 6 close to the center axis of the vehicle body, and the guide ring body 2 of the seat belt 7 is installed on the inner boss 4 of the guide ring installation plate 1. The above structure is suitable for the situation where the guide ring body 2 is far away from the rear side window inner panel 6, which can avoid structural deformation and tearing caused by excessive cantilever structure force arm when the guide ring body 2 is installed, avoid the risk of failure of the seat belt 7, and improve the safety during driving.

[0030] In this embodiment, by providing an inner boss 4 on the guide ring mounting plate 1, the structural strength of the corresponding portion of the guide ring mounting plate 1 is effectively enhanced, so that the connection position of the guide ring body 2 has better structural strength, avoiding the situation where the distance between the guide ring body 2 and the rear side window inner panel 6 is too large, and helping to reduce the local stress at the installation position of the rear side window inner panel 6, avoiding structural deformation and tearing at this position, and ensuring the effectiveness of the seat belt 7.

[0031] Specifically, the guide ring mounting plate 1 is arranged on the side of the rear side window inner plate 6 close to the center axis of the vehicle body, that is, the position in the vehicle for installing the seat belt 7, so as to reduce the force arm size of the cantilever structure when the guide ring body 2 is installed, avoid deformation and tearing of the structure, avoid failure of the seat belt 7, ensure the protection of the seat belt 7 to the passengers, and avoid danger in the formation process.

[0032] In a possible implementation, the above-mentioned characteristic guide ring body 2 and the inner boss 4 can be adopted as follows Figures 2 to 4 See the structure shown. Figures 2 to 4 A gasket 5 is provided between the guide ring body 2 and the inner boss 4 , and the connecting member 3 passes through the gasket 5 .

[0033] In this embodiment, by setting a gasket 5 between the guide ring body 2 and the inner boss 4, a safe gap between the guide ring body 2 and the guide ring mounting plate 1 (specifically referring to the side of the inner boss 4 close to the center axis of the vehicle body) is ensured, and tearing and deformation of the installation position of the guide ring body 2 can be effectively avoided, thereby avoiding the risk of failure of the seat belt 7.

[0034] Specifically, the thickness of the washer 5 should be set between 4-6 mm, and the protruding size parameters of the inner boss 4 should be set according to the installation position of the guide ring body 2. Then, by setting the above-mentioned washer 5, a safety gap of 4-6 mm is ensured between the side of the guide ring body 2 and the side of the inner boss 4 close to the center axis of the vehicle body, thereby avoiding structural tearing and deformation of the installation structure of the guide ring body 2 caused by the excessive cantilever, thereby improving the position reliability of the installation of the guide ring body 2.

[0035] In a possible implementation, the above-mentioned characteristic connecting member 3 can be adopted as follows Figures 2 to 4 See the structure shown. Figures 2 to 4 The connecting member 3 includes a mounting bolt 31 that passes through the guide ring body 2 and the inner boss 4 and a mounting nut 32 that is threadedly connected to the mounting bolt 31 . The mounting nut 32 is located between the inner boss 4 and the rear side window inner panel 6 .

[0036] In this embodiment, the connecting member 3 is in the form of a combination of a mounting bolt 31 and a mounting nut 32, which facilitates the installation and removal of the guide ring body 2 and facilitates the connection of the structure. The mounting bolt 31 is set through the side wall of the inner boss 4, and is threadedly connected by the mounting nut 32 set inside the inner boss 4 to achieve the locking of the axial position of the mounting bolt 31, ensuring that the mounting ring can be effectively fixed by the mounting bolt 31, and achieving a reliable installation effect.

[0037] Specifically, the mounting nut 32 can be pre-welded to the inner wall of the inner boss 4 (that is, the side wall of the inner boss 4 close to the rear side window inner panel 6), and the mounting bolt 31 is sequentially passed through the guide ring body 2, the washer 5 and the side wall of the inner boss 4, and the threads of the mounting bolt 31 and the mounting nut 32 are made convenient for the connection operation, avoiding the tediousness of the operator supporting the mounting bolt 31 and the mounting nut 32 on the inner and outer sides of the inner boss 4 respectively, thereby improving the installation efficiency and simplifying the operation steps.

[0038] In a possible implementation, the above-mentioned characteristic inner boss 4 can be adopted as follows Figures 5 and 6 See the structure shown. Figures 5 and 6 The inner boss 4 includes a mounting portion 41 for mounting the guide ring body 2 and a plurality of bending portions 42 respectively connected to the outer periphery of the mounting portion 41 . The bending portions 42 extend toward one side of the rear side window inner panel 6 and are connected to the rear side window inner panel 6 .

[0039] In this embodiment, the mounting portion 41 of the inner boss 4 is for the mounting bolt 31 to pass through, and the bent portion 42 on the outer periphery of the mounting portion 41 is used to form a certain distance between the mounting portion 41 and the side wall of the rear side window inner panel 6. The outer edge of the bent portion 42 is connected to the rear side window inner panel 6 to ensure that the mounting portion 41 protrudes toward the inner side of the vehicle body, thereby avoiding the problem of excessive cantilever caused by the guide ring body 2 being directly installed on the inner side of the rear side window inner panel 6.

[0040] Specifically, the bending portions 42 are distributed around the mounting portion 41, respectively extending toward one side close to the rear side window inner panel 6, and have a tendency to tilt toward the outer periphery of the mounting portion 41, so as to ensure the structural strength of the inner boss 4, while also enhancing the reliability of the connection with the rear side window inner panel 6, thereby ensuring the reliability of the installation of the guide ring body 2.

[0041] The bending portions 42 are specifically arranged according to the specific shape of the mounting portion 41. If the mounting portion 41 is circular, three or more bending portions 42 are arranged at intervals on the outer periphery of the mounting portion 41. If the mounting portion 41 is quadrilateral, at least one bending portion 42 is arranged on each side of the outer periphery of the mounting portion 41. More than two bending portions 42 can be arranged at intervals on the edge with a larger local length, so as to ensure that each point can form a supporting effect on the mounting portion 41 and ensure the structural strength of the mounting portion 41.

[0042] In a possible implementation, the characteristic bending portion 42 may be implemented as follows: Figures 2 to 6 See the structure shown. Figures 2 to 6 The bending portions 42 are respectively connected with connecting portions connected to the inner wall of the rear side window inner plate 6 , the connecting portions extend toward the outer periphery of the mounting portion 41 , and two adjacent connecting portions are spaced apart.

[0043] In this embodiment, by providing a connecting portion at the edge of the bending portion 42, the contact area between the inner boss 4 and the rear side window inner panel 6 can be increased, the reliability of the connection can be ensured, and the force applied to the installation position of the guide ring body 2 can be evenly distributed to the rear side window inner panel 6.

[0044] Specifically, the connecting portion is welded to the rear side window inner plate 6. In addition, according to the extension length of the bent portion 42 on the edge of the mounting portion 41, one or more connecting portions may be provided for the same bent portion 42, and each connecting portion is welded to different positions of the rear side window inner plate 6.

[0045] In some embodiments, the characteristic bending portion 42 and the mounting portion 41 may be formed as follows: Figures 5 and 6 See the structure shown. Figures 5 and 6 An inwardly concave reinforcing portion 44 is provided at the junction of the bending portion 42 and the mounting portion 41, and an outwardly convex reinforcing portion 45 is provided at the junction of the bending portion 42 and the connecting portion.

[0046] In this embodiment, the bending portion 42 and the mounting portion 41 are formed in an integrally formed structure. By providing an inner concave reinforcement portion 44 at the junction of the bending portion 42 and the mounting portion 41, the connection strength between the two can be effectively enhanced to form a reinforcement structure in the form of a rib plate, which can effectively control the structural rebound of the inner boss 4 under stress.

[0047] On the basis of the above structure, the bending portion 42 and the connecting portion also adopt an integrally formed structure. By providing an outwardly convex reinforcement portion 45 at the junction of the bending portion 42 and the connecting portion, the connection strength between the two can be effectively enhanced to form a reinforcement structure in the form of a rib plate, which can effectively control the structural rebound of the inner boss 4 under stress.

[0048] Furthermore, chamfers are respectively provided at the position where the bending portion 42 and the mounting portion 41 meet and at the position where the bending portion 42 and the connecting portion meet, and the chamfer radius is 2mm-4mm. This setting can effectively control the bending rebound of the bending portion 42 or the mounting portion 41 and improve the stability of the structure.

[0049] In some embodiments, the above-mentioned characteristic connection portion can be adopted as follows Figures 5 and 6 See the structure shown. Figures 5 and 6 The connecting part includes an upper connecting part 431 extending upward, a lower connecting part 432 extending downward, a front connecting part 433 extending toward the front side of the vehicle body, and a rear connecting part 434 extending toward the rear side of the vehicle body. The upper connecting part 431, the lower connecting part 432, the front connecting part 433 and the rear connecting part 434 are respectively welded to the rear side window inner panel 6.

[0050] In this embodiment, the mounting portion 41 is an approximately rectangular structure, the long side of the mounting portion 41 extends in the up-down direction, and the short side of the mounting portion 41 extends in the front-to-back direction. When the lower safety belt 7 is subjected to a pulling force forward and downward, the above-mentioned structural arrangement facilitates improving the resistance of the guide ring body 2 when subjected to force, thereby ensuring the installation reliability of the guide ring body 2.

[0051] Specifically, the upper side edge of the mounting portion 41 is provided with an upper connecting portion 431, and the lower side edge is provided with a lower connecting portion 432, and one upper connecting portion 431 and one lower connecting portion 432 are provided respectively. The outer convex reinforcement portion 45 is selected and arranged according to the actual area of ​​the upper connecting portion 431, the lower connecting portion 432, the front connecting portion 433 and the rear connecting portion 434, and sufficient welding area should be ensured.

[0052] The welding points of the upper connecting part 431 and the lower connecting part 432 are arranged on the large surface of the rear side window inner panel 6, the welding points of the rear connecting part 434 are arranged on the vertical surface of the rear side window frame, and the welding points of the front connecting part 433 are arranged on the stopper. The stopper and the vertical surface of the window frame have high rigidity, which can effectively improve the overall rigidity of the installation structure of the guide ring body 2.

[0053] In some embodiments, the above-mentioned characteristic connection portion can be adopted as follows Figures 5 and 6 See the structure shown. Figures 5 and 6 Two front connecting parts 433 are arranged at intervals in the vertical direction, and the rear connecting part 434 extends downward from the upper edge of the inner boss 4 to the lower edge of the inner boss 4. Two front connecting parts 433 are arranged at intervals in the vertical direction, and the connection areas of the two front connecting parts 433 are similar, which is convenient for ensuring the reliability of connection at different positions up and down. The rear connecting part 434 extends in the vertical direction to form a strip-shaped structure, which can further increase the welding area between the rear connecting part 434 and the vertical surface of the rear side window frame, so as to resist the pulling force of the safety belt 7 from the front side of the inner boss 4.

[0054] In a possible implementation, the feature installation portion 41 may be implemented as follows: Figures 5 and 6 See the structure shown. Figures 5 and 6 The mounting portion 41 is provided with a main positioning hole 411 for the connecting member 3 to pass through and a secondary positioning hole 412 located below the main positioning hole 411 .

[0055] In this embodiment, the main positioning hole 411 provided on the mounting portion 41 is used for the mounting bolt 31 to pass through, and a two-point positioning function is formed by the main positioning hole 411 and the auxiliary positioning hole 412, and the main positioning hole 411 and the auxiliary positioning hole 412 are used to perform structural positioning of the guide ring body 2. An avoidance hole 61 is provided on the rear side window inner plate 6 to prevent the mounting bolt 31 from interfering with the rear side window inner plate 6 after the guide ring body 2 is installed, thereby ensuring a reasonable layout of the structure and improving the reliability of the structural connection.
