[0039] The safety belt retractor in the vehicle can have an emergency locking function. When the vehicle is in emergency braking, frontal collision or vehicle rollover, the safety belt retractor can instantly lock the safety belt to fix the occupant on the seat to avoid the occupant from falling out of the vehicle or colliding. Therefore, the safety belt retractor mounting assembly for fixing the safety belt retractor must have sufficient strength and stability to ensure the reliability of the connection between the safety belt retractor and the vehicle.

[0040] The embodiment of the present application provides a rear-row safety belt retractor mounting assembly which can be used for fixing a rear-row safety belt retractor and can be fixed in the vehicle interior, so that the rear-row safety belt retractor can be fixed on the vehicle through the rear-row safety belt retractor mounting assembly. Figure 1 is a structural schematic view of a rear-row safety belt retractor mounting assembly provided by the embodiment of the present application. As shown in Figure 1 , the rear-row safety belt retractor mounting assembly can include a first mounting plate 100 and a second mounting plate 200.

The side of the second plate body 102 in the first mounting plate 100 away from the first plate body 101 can be the second side A2 of the first mounting plate 100, that is, the side of the second plate body 102 in the first mounting plate 100 away from the first plate body 101 can be fixedly connected with the C pillar 020 of the vehicle.

[0045] In the first mounting plate 100, the plane of the first plate body 101 can intersect the plane of the second plate body 102, that is, the plane of the first plate body 101 is not parallel to the plane of the second plate body 102.

And the first mounting plate 100 and the second mounting plate 200 can form a box-shaped structure, that is, at the fixed positions of the rear seat belt retractor mounting assembly on the rear roof cross beam 010 and the C pillar 020, the first mounting plate 100, the second mounting plate 200, the rear roof cross beam 010 and the C pillar 020 can form a closed structure, so that the strength and stability of the connection between the rear seat belt retractor mounting assembly and the rear roof cross beam 010 and the C pillar 020 are higher, and the reliability of the connection between the seat belt retractor fixed on the first mounting plate 100 and the vehicle is improved.

[0047] In summary, the embodiment of the present application provides a rear seat belt retractor mounting assembly, comprising a first mounting plate and a second mounting plate. The structure of the first mounting plate and the second mounting plate can be adapted to the mounting position of the rear seat belt retractor mounting assembly on the rear roof cross beam and the C pillar. The first mounting plate and the second mounting plate can form a box-shaped structure, that is, at the fixed position of the rear seat belt retractor mounting assembly on the rear roof cross beam and the C pillar, the first mounting plate, the second mounting plate, the rear roof cross beam and the C pillar can form a closed structure, so that the strength and stability of the connection between the rear seat belt retractor mounting assembly and the rear roof cross beam and the C pillar are higher, thereby improving the reliability of the connection between the seat belt retractor fixed on the first mounting plate and the vehicle.

[0048] Optionally, Figure 3 is another structural schematic diagram of a rear seat belt retractor mounting assembly provided by the embodiment of the present application. As shown in Figure 3 , the first plate body 101 in the first mounting plate 100 can comprise a first sub-plate body 1011 and a second sub-plate body 1012 connected together.

For this purpose, the first sub-plate body 1011, the second sub-plate body 1012 and the second plate body 102 in the first mounting plate 100 can be a semi-closed structure with three connected surfaces.

[0050] The second sub-plate body 1012 in the first plate body 101 can be arranged opposite to the second mounting plate 200. Since the first side B1 of the second mounting plate 200 can be adapted to be fixedly connected with the first plate body 101 and the second plate body 102 simultaneously, here, the first side B1 of the second mounting plate 200 can be adapted to be fixedly connected with the first sub-plate body 1011 in the first plate body 101 and the second plate body 102 simultaneously. Therefore, the first sub-plate body 1011 in the first plate body 101 of the first mounting plate 100, the second sub-plate body 1012 in the first plate body 101 of the first mounting plate 100, the second plate body 102 of the first mounting plate 100, and the second mounting plate 200 can enclose a box-shaped structure with four connected sides. Further, the first sub-plate body 1011 in the first plate body 101 of the first mounting plate 100, the second sub-plate body 1012 in the first plate body 101 of the first mounting plate 100, the second plate body 102 of the first mounting plate 100, the second mounting plate 200, the rear top beam 010, and the C pillar 020 can enclose a box-shaped closed structure with six connected sides, so that the strength and stability of the connection between the rear seat belt retractor mounting assembly and the rear top beam 010 and the C pillar 020 are higher.

When the worker needs to install the seat belt retractor on the rear seat belt retractor mounting assembly, the worker can first insert part of the retractor into the first pre-hanging hole S11, and then move the retractor from the first pre-hanging hole S11 to the second pre-hanging hole S12 to pre-hang the retractor in the second pre-hanging hole S12 to achieve pre-hanging of the retractor. Here, the maximum distance L1 of the retractor moving in the second pre-hanging hole S12 can be 11.5 mm. And after the retractor is pre-hung in the second pre-hanging hole S12, the bolt hole on the retractor can be aligned with the retractor mounting hole S2 of the second plate body 102, and the worker can fix and connect the retractor and the second plate body 102 together through bolts and nuts, so as to achieve the installation of the retractor on the second plate body 102.

[0069] In the present application, as shown in Figure 7 The second plate body 102 of the first mounting plate 100 can have two reinforcing ribs 1021, and the two reinforcing ribs 1021 of the second plate body 102 can be used to fit the felt in the rear seat belt retractor to avoid abnormal noise from the rear seat belt retractor through the felt. Here, the height of each reinforcing rib 102 in the second plate body 102 can be 2 mm, and the width can be 16.5 mm.

[0070] In summary, the embodiment of the present application provides a rear seat belt retractor mounting assembly, comprising a first mounting plate and a second mounting plate. The structure of the first mounting plate and the second mounting plate can be adapted to the mounting position of the rear seat belt retractor mounting assembly on the rear roof cross beam and the C pillar. The first mounting plate and the second mounting plate can form a box-shaped structure, that is, at the fixed position of the rear seat belt retractor mounting assembly on the rear roof cross beam and the C pillar, the first mounting plate, the second mounting plate, the rear roof cross beam and the C pillar can form a closed structure, so that the strength and stability of the connection between the rear seat belt retractor mounting assembly and the rear roof cross beam and the C pillar are higher, thereby improving the reliability of the connection between the seat belt retractor fixed on the first mounting plate and the vehicle.

[0071] The embodiment of the present application also provides a vehicle, comprising a rear roof cross beam, a C pillar, a seat belt retractor and a rear seat belt retractor mounting assembly. The rear seat belt retractor mounting assembly in the vehicle can be the rear seat belt retractor mounting assembly in the above-mentioned embodiment. The seat belt retractor in the vehicle can be fixed on the rear seat belt retractor mounting assembly, and the rear seat belt retractor mounting assembly can be fixedly connected with the rear roof cross beam and the C pillar. Here, the rear seat belt retractor mounting assembly, the rear roof cross beam and the C pillar can form a closed structure, so that the strength and stability of the connection between the rear seat belt retractor mounting assembly and the rear roof cross beam and the C pillar are higher, thereby improving the reliability of the connection between the seat belt retractor fixed on the first mounting plate and the vehicle.
