Description

Technical Field

[0001] This utility model relates to the field of vehicles, and in particular to a seat belt retractor assembly and a vehicle. Background Technology

[0002] Seatbelt retractors in vehicles are used to store seatbelts. In related technologies, the seatbelt retractor is typically fixed to a mounting plate, which is then fixed to the vehicle structure, such as a coat rack. When a user pulls the seatbelt, the force exerted on the retractor applies a bending moment, causing it to tend to rotate around its mounting point. This pressure from the retractor against the mounting plate can deform or even damage the plate. Therefore, improvements are needed. Utility Model Content

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a seatbelt retractor assembly and vehicle that, by making the second plane coplanar with the first plane or by making the distance between the second plane and the first plane less than 5mm, brings the distance between the connecting hole and the seatbelt outlet closer. This allows the user to pull the seatbelt when retracting it, as the force exerted on the seatbelt is closer to the plane containing the connecting hole, reducing the bending moment applied to the seatbelt retractor, reducing the compressive force exerted by the seatbelt retractor on the mounting plate, reducing the deformation or damage to the mounting plate caused by the seatbelt retractor, and enhancing the safety performance of the mounting plate.

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] The following is for reference. Figures 1-7 The present invention describes a seatbelt retractor assembly 10 according to an embodiment of the present invention.

[0034] According to the first aspect of the present invention, a seat belt retractor assembly 10, referring to... Figure 2 The system includes a mounting plate 20 and a seatbelt retractor 30. The seatbelt retractor 30 is mounted on the mounting plate 20 and includes a retractor housing and a winding mechanism 35. The retractor housing has a storage cavity for storing the seatbelt 41. The winding mechanism 35 is used to wind or release the seatbelt 41. The retractor housing has a seatbelt outlet 33 communicating with the storage cavity and a connection hole 34 connecting to the mounting plate 20. For example, the seatbelt retractor 30 and the mounting plate 20 are fixedly connected by fasteners 40.

[0035] In this design, when the seat belt 41 is pulled out, the plane containing the portion of the seat belt 41 that passes through the seat belt outlet 33 is the first plane 36, and the plane containing the connecting hole 34 is the second plane 37. The second plane 37 and the first plane 36 are coplanar, or the distance between the second plane 37 and the first plane 36 is 'a', where 'a' is less than 5 mm. By having the second plane 37 and the first plane 36 coplanar, or by having the distance between the second plane 37 and the first plane 36 less than 5 mm, the distance between the connecting hole 34 and the seat belt outlet 33 is closer. This reduces the bending moment exerted on the retractor housing by the force (e.g., F in the attached figure) when pulling out or retracting the seat belt 41, and reduces the pressing force on the mounting plate 20 when the seat belt retractor 30 rotates around the mounting hole 21. This makes the mounting plate 20 less prone to bending or damage, thus enhancing the safety performance of the mounting plate 20. By making the distance a between the second plane 37 and the first plane 36 less than 5mm, when the user needs to take out or retract the seat belt 41, the bending moment exerted on the seat belt retractor 30 by the force of taking out or retracting the seat belt 41 from the seat belt outlet 33 is smaller, the tendency of the seat belt retractor 30 to rotate along the connection hole 34 is smaller, and the squeezing force of the seat belt 41 shell on the mounting plate 20 is smaller, so that the mounting plate 20 is not easily deformed by the pressure of the seat belt 41 shell, thus improving the safety performance of the mounting plate 20.

[0036] For example, both the connecting hole 34 and the seat belt outlet 33 are located on the upper side of the retractor housing. The seat belt retractor 30 is fixed to the lower side of the mounting plate 20, and the seat belt retractor 30 and the mounting plate 20 are fixedly connected by fasteners 40. The distance between the second plane 37 and the first plane 36 is less than 5mm. When the user needs to remove the seat belt 41, the user pulls the seat belt 41 out from the seat belt outlet 33. At this time, the force exerted by pulling out the seat belt 41 on the seat belt retractor 30 has a small bending moment, the tendency of the seat belt retractor 30 to rotate along the connecting hole 34 is small, and the squeezing force of the seat belt retractor 30 on the mounting plate 20 is small, making it less likely for the mounting plate 20 to be deformed by the pressure of the seat belt 41 housing.

[0037] For example, the second plane 37 is coplanar with the first plane 36. By making the second plane 37 coplanar with the first plane 36, when the user needs to remove or retract the seat belt 41, the force used to remove or retract the seat belt 41 from the seat belt outlet 33 does not apply a bending moment to the seat belt retractor 30. The seat belt retractor 30 does not tend to rotate along the connection hole 34, and the seat belt 41 shell does not add additional compressive force to the mounting plate 20, making the mounting plate 20 less likely to be deformed by the pressure of the seat belt 41 shell, thus improving the safety performance of the mounting plate 20.

[0038] For example, the distance between the second plane 37 and the first plane 36, which are coplanar, can be 2 mm.

[0039] According to the embodiment of the present utility model, the seat belt retractor assembly 10, by making the second plane 37 coplanar with the first plane 36 or the distance between the second plane 37 and the first plane 36 less than 5mm, makes the distance between the connecting hole 34 and the seat belt outlet 33 closer. This allows the force exerted by the user when pulling the seat belt 41 to pull it to be closer to the plane where the connecting hole 34 is located, reducing the bending moment applied to the seat belt retractor 30, reducing the compressive force exerted by the seat belt retractor 30 on the mounting plate 20, reducing the deformation or damage to the mounting plate 20 caused by the seat belt retractor 30, and enhancing the safety performance of the mounting plate 20.

[0040] According to some embodiments of this utility model, refer to Figure 3 Mounting plate 20 has mounting holes 21 formed therein. Fasteners 40 pass through mounting holes 21 and connecting holes 34 to fix the seat belt retractor 30 to the mounting plate 20. The diameter of the mounting hole 21 is d, which is less than 14mm. By using fasteners 40 to pass through mounting holes 21 and connecting holes 34 to fix the seat belt retractor 30 to the mounting plate 20, the fixation between the seat belt retractor 30 and the mounting plate 20 can be more secure, preventing the seat belt retractor 30 from falling off and improving safety performance. For example, fasteners 40 can be bolts and nuts. Since the second plane 37 is coplanar with the first plane 36 or the distance between the second plane 37 and the first plane 36 is less than 5mm, the mounting plate 20 is less likely to be bent or damaged by the seat belt retractor 30, thus improving the safety performance of the mounting plate 20. By making the diameter d of the mounting hole 21 less than 14mm, the diameter of the mounting hole 21 can be appropriately reduced while ensuring the safety performance of the mounting plate 20, thereby reducing the size of the fastener 40 and achieving the effect of reducing costs.

[0041] For example, the diameter of mounting hole 21 is 12mm.

[0042] According to some embodiments of this utility model, refer to Figure 3 The thickness of the mounting plate 20 is b, where b is less than 2.2 mm. For example, b can be 1.9 mm, 2.0 mm, 2.1 mm, etc. Since the second plane 37 is coplanar with the first plane 36, or the distance between the second plane 37 and the first plane 36 is less than 5 mm, the mounting plate 20 is less likely to be bent or damaged by the seatbelt retractor 30, thus improving the safety performance of the mounting plate 20. By making the thickness b of the mounting plate 20 less than 2.2 mm, the thickness of the mounting plate 20 can be appropriately reduced while ensuring its safety performance, thereby reducing costs.

[0043] According to some embodiments of this utility model, refer to Figures 4-7The mounting plate 20 includes a first mounting plate 22 and a second mounting plate 23 stacked along the thickness direction of the mounting plate 20. The first mounting plate 22 and the second mounting plate 23 are connected, and the thickness of the mounting plate 20 is the sum of the thickness of the first mounting plate 22 and the thickness of the second mounting plate 23. By including the first mounting plate 22 and the second mounting plate 23 stacked along the thickness direction of the mounting plate 20, the strength of the mounting plate 20 can be increased. Furthermore, compared with the related art schemes that include three mounting plates 20 stacked along the thickness direction of the mounting plate 20, the number of components can be reduced, and the installation efficiency of the mounting plate 20 can be improved.

[0044] For example, the first mounting plate 22 is located on top of the second mounting plate 23. The material of the first mounting plate 22 is 590DP, and the thickness of the first mounting plate 22 is 1.2mm. The material of the second mounting plate 23 is HC260, and the thickness of the second mounting plate 23 is 0.7mm. The thickness of the mounting plate 20 is 1.9mm.

[0045] According to some embodiments of this utility model, refer to Figure 7 The first mounting plate 22 and the second mounting plate 23 are welded together. By welding the first mounting plate 22 and the second mounting plate 23 together, the connection between the first mounting plate 22 and the second mounting plate 23 can be made more secure, thus improving safety performance.

[0046] According to some embodiments of this utility model, refer to Figure 7 The welding point between the first mounting plate 22 and the second mounting plate 23 is designated as the first welding point 24. Multiple first welding points 24 are spaced apart. The mounting plate 20 includes a mounting portion 26, which is connected to the rewinder housing. At least a portion of the first welding points 24 are located on the mounting portion 26. By having multiple first welding points 24 spaced apart, the connection between the first mounting plate 22 and the second mounting plate 23 can be made more secure. Furthermore, by having at least a portion of the first welding points 24 located on the mounting portion 26, the connection between the first mounting plate 22 and the second mounting plate 23 on the mounting portion 26 can be made more secure, improving the structural strength of the mounting portion 26. This ensures that the portion of the mounting plate 20 connected to the winder has sufficient structural strength, thus enhancing safety performance.

[0047] According to some embodiments of this utility model, refer to Figure 6The mounting plate 20 is provided with a plurality of spaced-apart second welding points 25 for mounting and fixing the mounting plate 20. At least a portion of the plurality of second welding points 25 is arranged along the periphery of the mounting plate 20. By providing a plurality of spaced-apart second welding points 25 for mounting and fixing the mounting plate 20, the fixing of the mounting plate 20 can be made more reliable, improving safety performance; by arranging at least a portion of the plurality of second welding points 25 along the periphery of the mounting plate 20, the periphery of the mounting plate 20 can be fixed, making the fixing of the mounting plate 20 more reliable.

[0048] For example, mounting plate 20 can be fixed to the coat rack of vehicle body 42.

[0049] According to some embodiments of this utility model, refer to Figure 2 The connecting hole 34 and the seat belt outlet 33 are both located at the upper end of the retractor housing. The mounting plate 20 has a mounting portion 26, which is connected to the retractor housing. The mounting portion 26 is located on the upper side of the retractor housing. By locating both the connecting hole 34 and the seat belt outlet 33 at the upper end of the retractor housing, and with the mounting portion 26 located on the upper side of the retractor housing, the seat belt retractor 30 can be prevented from being affected by other structures such as the seat back, allowing the seat belt 41 to be easily pulled out or retracted.

[0050] According to some embodiments of this utility model, refer to Figure 2 A portion of the mounting plate 20 protrudes upward to form a mounting portion 26. A receiving groove 27 is defined on the lower side of the mounting portion 26, and at least a portion of the retractor housing is located within the receiving groove 27. By defining the receiving groove 27 on the lower side of the mounting portion 26, and ensuring that at least a portion of the retractor housing is located within the receiving groove 27, installation of the seatbelt retractor 30 is facilitated, and the excessive size of the seatbelt retractor 30 below the mounting plate 20, which could lead to interference with other components, is avoided.
