[0032] The following refers to Figures 1-4 Describe the installation structure 100 of the seat belt retractor according to an embodiment of the present utility model.

[0033] The installation structure 100 of the seat belt retractor according to the first aspect embodiment of the present utility model is for a vehicle and is used to retract the seat belt 33 of the vehicle. When using the seat belt 33, the seat belt 33 can be released from the seat belt retractor 30 by an external force; when not using the seat belt 33, the seat belt retractor 30 retracts the seat belt 33 to facilitate the storage of the seat belt 33.

[0034] The installation structure 100 of the seat belt retractor is used for the installation of the seat belt retractor 30. The installation structure 100 of the seat belt retractor includes an outer wheelhouse panel 11. The installation structure 100 of the seat belt retractor further includes an outer side panel 13. An installation cavity 16 is defined between the outer side panel 13 and the outer wheelhouse panel 11. The seat belt retractor 30 is installed in the installation cavity 16 to save space inside the vehicle. An avoidance hole 113 is provided on the outer wheelhouse panel 11. The avoidance hole 113 communicates with the installation cavity 16. The seat belt retractor 30 is installed at the avoidance hole 113 of the outer wheelhouse panel 11. The seat belt 33 extends into the vehicle through the avoidance hole 113. A wheel is provided below the outer wheelhouse panel 11. When the vehicle is running, the wheel will generate noise, and the noise can be transmitted into the vehicle through the avoidance hole 113, and the passengers will feel a relatively large noise, resulting in poor NVH performance of the vehicle.

[0035] The installation structure 100 of the seat belt retractor further includes a sound insulation board 20. The sound insulation board 20 is installed on the side of the outer wheelhouse panel 11 facing away from the vehicle interior. The sound insulation board 20 is used to define a sound insulation cavity 25 with the outer wheelhouse panel 11. The avoidance hole 113 communicates with the sound insulation cavity 25. The sound insulation cavity 25 is a part of the installation cavity 16. At least part of the seat belt retractor 30 is located in the sound insulation cavity 25. It can be that part of the seat belt retractor 30 is located in the sound insulation cavity 25 and part of the seat belt retractor 30 is located in the avoidance hole 113; it can also be that the entire seat belt retractor 30 is located in the sound insulation cavity 25.

[0036] The sound insulation cavity 25 can block the noise path transmitted into the vehicle, avoid the noise from being transmitted into the vehicle, and can improve the NVH performance of the vehicle; and the sound insulation board 20 is fixedly connected to the outer wheelhouse panel 11 around the avoidance hole 113. The sound insulation board 20 plays a role in supporting the avoidance hole 113, so that the anti-deformation ability of the avoidance hole 113 is enhanced, which helps to improve the NVH performance of the vehicle.

[0037] According to the installation structure 100 of the seat belt retractor of the embodiment of the present invention, the sound insulation board 20 and the outer wheelhouse panel 11 define a sound insulation cavity 25. The sound insulation cavity 25 can block the noise path transmitted into the vehicle, avoid the noise from being transmitted into the vehicle; and the sound insulation board 20 is fixedly connected to the outer wheelhouse panel 11 around the avoidance hole 113. The sound insulation board 20 plays a role in supporting the avoidance hole 113, so that the anti-deformation ability of the avoidance hole 113 is enhanced, which helps to improve the NVH performance of the vehicle.

[0038] According to some embodiments of the present invention, refer to Figures 2-4, the mounting structure 100 of the seat belt retractor further includes an inner side panel 14, and the lower end of the inner side panel 14 is connected to the upper end of the outer wheelhouse panel 11. The sound insulation panel 20 extends in the up and down direction, the upper end of the sound insulation panel 20 is connected to the inner side panel 14, and the other circumferences of the sound insulation panel 20 are connected to the outer wheelhouse panel 11. The vibration received by the sound insulation panel 20 can be transmitted to the inner side panel 14, which can increase the vibration transmission path of the sound insulation panel 20 to disperse the vibration received by the sound insulation panel 20. Connecting the sound insulation panel 20 to the inner side panel 14 and the outer wheelhouse panel 11 can increase the stability of the sound insulation panel 20 fixed to the vehicle, and thus can increase the structural strength of the sound insulation panel 20.

[0039] According to some embodiments of the present invention, referring to Figures 2-4 , the sound insulation panel 20 has a main body plate 21 and a bent plate 22. The bent plate 22 is connected to the outer peripheral edge of the main body plate 21, and the main body plate 21 and the bent plate 22 are arranged at an angle. The bent plate 22 is connected to the side of the main body plate 21 close to the vehicle interior, and the bent plate 22 is fixedly connected to both the inner side panel 14 and the outer wheelhouse panel 11, so that a sound insulation cavity 25 can be defined between the sound insulation panel 20 and the outer wheelhouse panel 11, which is convenient for the installation of the seat belt retractor 30. For example, the lower end of the main body plate 21 is directly connected to the outer wheelhouse panel 11, and the bent plate 22 is connected to the other circumferences of the main body plate 21. For example, the angle between the main body plate 21 and the bent plate 22 is in the range of 80° to 110°.

[0040] According to some embodiments of the present invention, referring to Figures 2-4 , the sound insulation panel 20 has a first connecting flange 23 and a second connecting flange 24. The first connecting flange 23 is fixedly connected to the inner side panel 14, which can increase the connection area between the sound insulation panel 20 and the inner side panel 14; the second connecting flange 24 is fixedly connected to the outer wheelhouse panel 11, which can increase the connection area between the sound insulation panel 20 and the outer wheelhouse panel 11, and thus can increase the connection strength of the sound insulation panel 20 fixed to the outer wheelhouse panel 11 and the inner side panel 14.

[0041] For example, the sound insulation panel 20 is a metal plate, and the first connecting flange 23 and the inner side panel 14 can be fixedly connected by spot welding, and the second connecting flange 24 and the outer wheelhouse panel 11 can also be fixedly connected by spot welding.

[0042] According to some embodiments of the present invention, referring to Figures 2-3 , the outer wheelhouse panel 11 includes a wheelhouse body 111 and an extension plate 112. The extension plate 112 is connected to one end of the wheelhouse body 111 and extends upward. An avoidance hole 113 is provided on the extension plate 112. The sound insulation panel 20 is connected to the wheelhouse body 111. In the first direction (refer to the attached Figure 3In the Y direction (the Y direction is the left - right direction of the vehicle), the wheelhouse body 111 has a first end 1111 and a second end 1112. In the first direction, the dimension between the first end 1111 and the sound insulation panel 20 is greater than the dimension between the sound insulation panel 20 and the second end 1112.

[0043] The wheelhouse body 111 and the sound insulation panel 20 between the sound insulation panel 20 and the second end 1112 of the wheelhouse body 111 define a sound insulation cavity 25. The wheelhouse body 111 between the first end 1111 of the wheelhouse body 111 and the sound insulation panel 20 is located outside the sound insulation cavity 25. As can be Figure 4 seen, there are two paths for noise to pass through the entire outer wheelhouse panel 11, namely the first path 41 and the second path 42 (the arrows of the first path 41 and the second path 42 in the attached Figure 4 figure are the noise transmission directions). The first path 41 is that the noise is blocked by the sound insulation panel 20 outside the sound insulation cavity 25, and the second path 42 is that the noise bypasses the sound insulation panel 20 and directly transmits into the vehicle interior. Since the dimension between the first end 1111 and the sound insulation panel 20 is greater than the dimension between the sound insulation panel 20 and the second end 1112, most of the noise is blocked by the sound insulation panel 20 outside the sound insulation cavity 25, and the noise transmitted into the vehicle interior is greatly attenuated, which significantly improves the NVH performance of the vehicle.

[0044] From the data, it can be known that the proportion of the noise blocked by the sound insulation panel 20 through the first path 41 is about 95%, and the proportion of the noise directly transmitted into the vehicle interior through the second path 42 is about 5%, and the interior noise is reduced by about 2 dB.

[0045] According to some embodiments of the present invention, referring to Figures 2-3 , the installation structure 100 of the seat - belt retractor further includes an inner side - wall panel 14. The inner side - wall panel 14 is connected to the upper end of the outer wheelhouse panel 11. The seat - belt retractor 30 has a first fixing portion 31, and the first fixing portion 31 is fixedly connected to the inner side - wall panel 14. By fixing the seat - belt retractor 30 to the inner side - wall panel 14 through the first fixing portion 31, the stability of the seat - belt retractor 30 installed on the vehicle can be increased.

[0046] In a specific example, the first fixing portion 31 includes a first fixing hole, and a first fixing nut 141 opposite to the first fixing hole is provided on the inner side - wall panel 14. A first fastener 311 can be passed through the first fixing hole and cooperate with the first fixing nut 141 to fix the seat - belt retractor 30 to the inner side - wall panel 14. When it is necessary to replace or repair the seat - belt 33, the seat - belt retractor 30 can be removed from the inner side - wall panel 14, which is convenient for the repair of the seat - belt 33.

[0047] According to some embodiments of the present invention, referring to Figures 2-3, the mounting structure 100 of the seat belt retractor further includes an inner wheelhouse panel 12. The inner wheelhouse panel 12 is connected to the side of the outer wheelhouse panel 11 close to the vehicle interior. The seat belt retractor 30 has a second fixing portion 32, and the second fixing portion 32 is fixedly connected to the inner wheelhouse panel 12. By fixing the seat belt retractor 30 to the inner wheelhouse panel 12 through the second fixing portion 32, the stability of the installation of the seat belt retractor 30 on the vehicle can be increased.

[0048] According to some embodiments of the present invention, referring to Figures 2-3 , the mounting structure 100 of the seat belt retractor further includes a mounting plate 15. The mounting plate 15 is connected to the inner wheelhouse panel 12, and the second fixing portion 32 is fixedly connected to the mounting plate 15. By providing the mounting plate 15, the installation of the second fixing portion 32 of the seat belt retractor 30 can be facilitated.

[0049] The sound insulation panel 20 is fixedly connected to the outer wheelhouse panel 11 and the inner side panel 14 around the avoidance hole 113. The sound insulation panel 20 functions to support the avoidance hole 113. The installation points of the first fixing portion 31 and the inner side panel 14 and the installation points of the second fixing portion 32 and the mounting plate 15 are arranged on the periphery of the avoidance hole 113. The sound insulation panel 20 can also function to support the installation points of the first fixing portion 31 and the inner side panel 14 and the installation points of the second fixing portion 32 and the mounting plate 15, which can improve the dynamic stiffness of the installation points of the seat belt retractor 30 and contribute to improving the NVH performance of the vehicle.

[0050] In a specific example, the mounting plate 15 is provided with a second fixing hole 151. The second fixing portion 32 includes a fixing plate 321, and the fixing plate 321 is provided with a second fixing nut opposite to the second fixing hole 151. The second fastener 322 can be passed through the second fixing hole 151 and cooperate with the second fixing nut to fix the seat belt retractor 30 to the mounting plate 15.
