[0023] Please refer to Figure 1 and Figure 2 , the present application provides a safety belt fixing device 100, which is used for fixed connection with a mounting beam 10, the side wall of the mounting beam 10 is provided with a limiting hole 11, the safety belt fixing device 100 comprises a safety belt assembly 20 and a locking piece 30, the locking piece 30 fixes the safety belt fixing assembly on the mounting beam 10. When the mounting beam 10 cooperates with the locking piece 30 to fix the safety belt assembly 20, the limiting hole 11 on the mounting beam 10 can enable the components in the safety belt fixing device 100 to be connected with the mounting beam 10 through the limiting hole 11. The mounting beam 10 in the embodiment is a seat cross beam 13 assembly in a vehicle 200, the mounting beam 10 serves as a support structure, the limiting hole 11 pre-provided on the side wall of the mounting beam 10 not only provides a positioning reference for the safety belt fixing device 100, but also enables the components in the safety belt fixing device 100 to further enhance the stability and reliability of the entire safety belt fixing device 100 through the limiting hole 11.

[0024] The safety belt assembly 20 comprises a safety belt body 21, a fixing bracket 22 and a limiting block 23. The fixing bracket 22 is connected to the end of the safety belt body 21 and abuts against the mounting beam 10. The locking member 30 is configured to fixedly connect the fixing bracket 22 to the mounting beam 10. One end of the limiting block 23 is connected to one side of the fixing bracket 22, and the other end is configured to extend into the limiting hole 11 of the mounting beam 10.

[0025] Specifically, the safety belt body 21 is directly subjected to load and is used to protect the safety of the driver and passengers. The fixing bracket 22 is used as a bridge between the safety belt body 21 and the mounting beam 10 and is fixedly connected to the mounting beam 10 by the locking member 30, thereby improving the connection stability between the safety belt body 21 and the mounting beam 10. One end of the limiting block 23 is connected to the fixing bracket 22, and the other end is designed to extend into the limiting hole 11 of the mounting beam 10. The limiting block 23 not only realizes the accurate positioning of the safety belt assembly 20 on the mounting beam 10, but also improves the connection stability between the safety belt assembly 20 and the mounting beam 10 through the limiting structure between the limiting block 23 and the limiting hole 11, thereby reducing the risk of loosening or falling of the safety belt assembly 20 in a dynamic environment.

[0026] In the safety belt fixing device 100, on the basis of the locking member 30 fixedly connecting the safety belt assembly 20 and the mounting beam 10, the limiting block 23 extends into the limiting hole 11 of the mounting beam 10, thereby further improving the connection strength between the safety belt assembly 20 and the mounting beam 10, reducing the risk of accidental loosening or falling of the safety belt assembly 20 in a dynamic environment, and improving the stability and reliability of the safety belt assembly 20.

[0027] Please refer to Figure 2 and Figure 3 In an embodiment, the limiting block 23 has an L-shaped structure and comprises a connecting portion 231 and a plug-in portion 232. One end of the connecting portion 231 is connected to the fixing bracket 22, and the other end is connected to the plug-in portion 232. The plug-in portion 232 extends into the limiting hole 11 away from one end of the connecting portion 231. The connecting portion 231 is a basic support structure of the limiting block 23, and the plug-in portion 232 is used to be inserted into the limiting hole 11. The hole wall of the limiting hole 11 provides a physical barrier for the plug-in portion 232, thereby reducing the risk of the fixing bracket 22 exceeding the predetermined movement range relative to the mounting beam 10.

[0028] Please refer to Figure 2 and Figure 3In an embodiment, the connection between the connecting portion 231 and the fixed support 22 is a circular arc transition structure, and the connection between the connecting portion 231 and the plug-in portion 232 is a circular arc transition structure. The circular arc transition structure not only maintains the continuity between the limiting block 23 and the fixed support 22, but also effectively disperses the stress concentration at the connection position, reduces the risk of fatigue cracks or fractures that may be caused by direct hard connection, thereby improving the overall structural strength and durability of the seat belt assembly 20.

[0029] In an embodiment, the fixed support 22 and the limiting block 23 are integrally formed, which improves the structural strength of the seat belt assembly.

[0030] In other embodiments, the fixed support 22 and the limiting block 23 can also be a split structure, which are connected together by, for example, welding or the like.

[0031] Please refer to Figure 2 and Figure 4 In an embodiment, the locking member 30 includes a fixed screw 31 and a fixed nut 32, and the fixed screw 31 is screwed with the fixed nut 32 through the fixed support 22. It can be understood that other locking methods can also be selected to fix the fixed support 22 and the mounting beam 10.

[0032] In an embodiment, the seat belt fixing device 100 of the present application can be adapted to pre-tightening seat belts, ordinary seat belts, and other general-purpose seat belts, thereby improving the versatility of the seat belt fixing device 100.

[0033] Please refer to Figure 1 and Figure 2 The present application also provides a vehicle 200 including the mounting beam 10 and the above-mentioned seat belt fixing device 100. The seat belt fixing device 100 is fixed on the mounting beam 10, which improves the product reliability of the seat belt, thereby improving the safety of the driver and passengers during driving.

[0034] Please refer to Figure 2 and Figure 4 In an embodiment, the mounting beam 10 is provided with a through hole 12, and the locking member 30 in the seat belt fixing device 100 fixes and connects the fixed support 22 and the mounting beam 10 through the through hole 12. The through hole 12 serves as the path for the locking member 30 to pass through the mounting beam 10, and the diameter of the through hole 12 is slightly larger than the maximum cross section of the locking member 30, so as to allow the locking member 30 to pass through smoothly and to exert the necessary pre-tightening force on the fixed support 22 and the mounting beam 10, thereby improving the stability of the fixed support 22 on the mounting beam 10.

[0035] Please refer to Figure 2 , Figure 3 and Figure 4In an embodiment, the mounting beam 10 comprises a seat cross beam 13 and a seat cross beam connecting plate 14, the seat cross beam connecting plate 14 is snap-fitted on the seat cross beam 13 and fixedly connected with the rocker beam 40 of the vehicle 200 at one end. The seat cross beam 13 serves as the main structure of the mounting beam 10 and is used to bear the weight of the seat and the driver and the impact force generated in the case of emergency braking or collision. The seat cross beam connecting plate 14 is a bridge connecting the seat cross beam 13 and the rocker beam 40, and the rocker beam 40, as a part of the vehicle body structure of the vehicle 200, provides strong support to the seat cross beam 13, further enhancing the stability of the seat system of the vehicle 200.

[0036] In the embodiment, one side of the seat cross beam 13 is provided with a first plug-in hole 131, and one side of the seat cross beam connecting plate 14 is provided with a second plug-in hole 141, and the first plug-in hole 131 and the second plug-in hole 141 are communicated to form a limiting hole 11. The first plug-in hole 131 and the second plug-in hole 141 correspond to each other in position to jointly form the limiting hole 11, which not only provides a positioning reference for the safety belt fixing device 100, but also enables the limiting block 23 in the safety belt fixing device 100 to further enhance the stability and reliability of the entire safety belt fixing device 100 through the limiting hole 11.

[0037] In the embodiment, the mounting beam 10 is the rear seat cross beam 13 structure of the seat.

[0038] It can be understood that the installation position of the safety belt assembly 20 is arranged at the position of the mounting beam 10, i.e., the installation position of the safety belt assembly 20 is arranged in the vehicle 200, which reduces the risk that the sealing performance of the mounting position of the safety belt assembly 20 in the rocker beam 40 in the prior art is affected by water when the vehicle 200 is wading.

[0039] Please refer to Figure 4 In an embodiment, the seat cross beam 13 and the seat cross beam connecting plate 14 are spaced apart and welded around the circumferential side of the locking piece 30, which not only improves the connection strength between the seat cross beam 13 and the seat cross beam connecting plate 14 and the installation rigidity at the position of the locking piece 30, but also eliminates the gap between the seat cross beam 13 and the seat cross beam connecting plate 14, thereby reducing the risk of moment attenuation of the locking piece 30 when fixing the mounting beam 10 and the fixed bracket 22.

[0040] In an embodiment, the materials of the seat cross beam 13 and the seat cross beam connecting plate 14 include sheet metal. In other embodiments, the seat cross beam 13 and the seat cross beam connecting plate 14 can also be made of other materials, which are not limited herein.

[0041] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application.
