[0029] The retractor mounting member 2 comprises a first plate body 201, a second flange 2011, a second lap joint 20111, a fifth flange 2012, a second plate body 202, a fourth flange 2021, and a sixth flange 2022. DETAILED DESCRIPTION

[0030] Embodiments of the present application are described in detail below with reference to examples shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0031] As shown in the drawings, Figures 1 to 9 The support column assembly 100 of the embodiment of the present application comprises a support column body 1 and a retractor mounting member 2. The support column body 1 comprises an inner plate 101 and a support member 102. The support member 102 is arranged on one side of the inner plate 101 in the thickness direction and connected to the inner plate 101. The retractor mounting member 2 is arranged on the other side of the inner plate 101 in the thickness direction and connected to the inner plate 101. In other words, the support member 102 and the retractor mounting member 2 are arranged on both sides of the inner plate 101 in the thickness direction, respectively, and connected to both sides of the inner plate 101, respectively.

[0032] The projection of at least a part of the retractor mounting member 2 and at least a part of the support member 102 in the thickness direction of the inner plate 101 overlaps and is connected through the inner plate 101. The projection of at least a part of the retractor mounting member 2 and at least a part of the support member 102 in the thickness direction of the inner plate 101 can be understood as: the projection of a part of the retractor mounting member 2 and a part of the support member 102 in the thickness direction of the inner plate 101 overlaps; or the projection of a part of the retractor mounting member 2 and the whole of the support member 102 in the thickness direction of the inner plate 101 overlaps; or the projection of the whole of the retractor mounting member 2 and a part of the support member 102 in the thickness direction of the inner plate 101 overlaps; or the projection of the whole of the retractor mounting member 2 and the whole of the support member 102 in the thickness direction of the inner plate 101 overlaps. Thus, at least a part of the retractor mounting member 2 and at least a part of the support member 102 form a lap joint area, in which the retractor mounting member 2, the support member 102, and the inner plate 101 are arranged in layers, and the inner plate 101 is clamped between the retractor mounting member 2 and the support member 102.

[0033] The support column assembly 100 of the embodiment of the present application, the retractor mounting member 2 is connected to the support member 102 of the support column body 1 in addition to being connected to the inner plate 101 of the support column body 1, and is connected through the inner plate 101. Compared with the related art in which the retractor mounting member is only connected to the inner plate, the connection strength between the retractor mounting member 2 and the support column plate body 1 is improved, thereby greatly reducing the risk of safety belt retractor pull-off failure and improving the safety of the vehicle with the support column assembly.

[0034] Therefore, the support column assembly 100 has the advantages of low risk of safety belt retractor pull-out failure.

[0035] In addition, it can be understood that the connection strength between the retractor mounting member 2 and the support column plate body 1 is improved, and the first-order installation modal of the retractor mounting member 2 is effectively improved, thereby reducing the abnormal sound problem of the retractor mounting member 2.

[0036] Optionally, at least a portion of the support member 102 forms a first lap joint portion 10211, and at least a portion of the retractor mounting member 2 forms a second lap joint portion 20111. The first lap joint portion 10211 and the second lap joint portion 20111 overlap in the thickness direction of the inner plate 101 and are connected by the inner plate 101.

[0037] Optionally, the first lap joint portion 10211 is welded to the inner plate 101, and the second lap joint portion 20111 is welded to the inner plate 101.

[0038] For example, the first lap joint portion 10211 and the inner plate 101 are welded by two spot welds, the second lap joint portion 20111 and the inner plate are welded by one spot weld, and the spot weld between the second lap joint portion 20111 and the inner plate overlaps with one of the spot welds between the first lap joint portion 10211 and the inner plate 101. In other words, the first lap joint portion 10211, the second lap joint portion 20111, and the inner plate 101 are connected by one three-layer spot weld.

[0039] Therefore, the connection strength of the first lap joint portion 10211 and the inner plate 101 and the second lap joint portion 20111 and the inner plate 101 is better, which is beneficial to further reduce the risk of safety belt retractor pull-out failure and improve the safety of the vehicle with the support column assembly 100.

[0040] In some embodiments, the support member 102 has at least one first flange 1021 connected to the inner plate 101, and the at least one first flange 1021 forms the first lap joint portion 10211. The retractor mounting member 2 has at least one second flange 2011 connected to the inner plate 101, and the at least one second flange 2011 forms the second lap joint portion 20111.

[0041] For example, as shown in FIG. 1, the support member 102 has two first flanges 1021, and the retractor mounting member 2 has two second flanges 2011. Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown, the inner plate 101 includes a first portion 103, a second portion 104 and a third portion 105 arranged in sequence along a width direction of the inner plate 101, wherein the first portion 103 and the third portion 105 both intersect with the second portion 104, and the first portion 103 is bent towards one side of the second portion 104 in a thickness direction, and the third portion 105 is bent towards the other side of the second portion 104 in the thickness direction. The thickness direction of the inner plate 101 is consistent with the Y direction (left-right direction) of the vehicle, and the width direction of the inner plate 101 can be consistent with the X direction (front-rear direction) of the vehicle.

[0042] The support 102 has two first flanges 1021, one of which is connected to the first portion 103, and the other of which is connected to the second portion 104. The retractor mounting 2 has two second flanges 2011, one of which is connected to the second portion 104, and the other of which is connected to the third portion 105. The projection of the first flange 1021 connected to the second portion 104 and the second flange 2011 connected to the second portion 104 in the thickness direction of the inner plate 101 overlaps, and the first flange 1021 connected to the second portion 104 forms a first lap joint 10211, and the second flange 2011 connected to the second portion 104 forms a second lap joint 20111.

[0043] The first lap joint 10211 is formed by the first flange 1021, and the second lap joint 20111 is formed by the second flange 2011, which not only facilitates the design and manufacture of the support 102 and the retractor mounting 2, but also helps to improve the connection stability of the first lap joint 10211, the second lap joint 20111 and the inner plate 101.

[0044] Optionally, the number of first flanges 1021 is a plurality, and the plurality of first flanges 1021 are arranged on different side edges of the support 102.

[0045] For example, as shown in the first embodiment of the present application, Figure 6 As shown, the support 102 is generally a rectangular plate, and the number of first flanges 1021 is two, and the two first flanges 1021 are arranged on two different side edges of the support 102, respectively.

[0046] By arranging a plurality of first flanges 1021 on different side edges of the support 102, the connection area of the support 102 and the inner plate 101 can be effectively improved, and the connection strength of the support 102 and the inner plate 101 can be improved, and the structural strength of the support column assembly 100 can be improved.

[0047] Optionally, the number of second flanges 2011 is a plurality, and the plurality of second flanges 2011 are arranged on different side edges of the support 102.

[0048] For example, as shown in the first embodiment of the present application,Figure 7 As shown, the outer periphery of the retractor mounting part 2 is generally rectangular, and there are two second flanges 2011, which are respectively provided on two different sides of the retractor mounting part 2.

[0049] By placing multiple second flanges 2011 on different sides of the retractor mounting member 2, the connection area between the retractor mounting member 2 and the inner panel 101 can be effectively increased, further improving the connection strength between the retractor mounting member 2 and the inner panel 101. This helps to further reduce the risk of seat belt retractor pull-out failure and improve the safety of vehicles with the support column assembly 100.

[0050] Optionally, the support column body 1 also includes a reinforcing plate (not shown in the figure), and the support member 102 also has at least one third flange 1022, which is connected to the reinforcing plate. The third flange 1022 and the first flange 1021 are located on different sides of the support member 102, the first flange 1021 is bent in a direction away from the third flange 1022, and the third flange 1022 is bent in a direction away from the first flange 1021.

[0051] For example, such as Figure 6 As shown, the first flange 1021 bends away from the third flange 1022, and the third flange 1022 bends away from the first flange 1021. There are two third flanges 1022, and the two third flanges 1022 and two first flanges 1021 are respectively located on four different sides of the support member 102. Specifically, one first flange 1021 and one third flange 1022 are arranged opposite each other along the height direction of the inner panel 101; another first flange 1021 and another third flange 1022 are arranged opposite each other along the width direction of the inner panel 101. The height direction of the inner panel 101 is consistent with the Z-direction (vertical direction) of the vehicle.

[0052] On the one hand, by connecting the third flange 1022 to the reinforcing plate, the connection strength between the support member 102 and the reinforcing plate can be improved, thereby increasing the structural strength of the support column assembly 100. On the other hand, the first flange 1021 is bent in the direction away from the third flange 1022, and the third flange 1022 is bent in the direction away from the first flange 1021, which facilitates the connection between the first flange 1021 and the inner plate 101, as well as the connection between the third flange 1022 and the reinforcing plate.

[0053] Optionally, there may be multiple third flanges 1022, which are provided on different sides of the support member 102.

[0054] For example, such as Figure 6As shown, the support piece 102 is generally a rectangular plate, and the number of the third flanges 1022 is two, and the two third flanges 1022 and the two first flanges 1021 are respectively arranged on the four different sides of the support piece 102.

[0055] By arranging the plurality of third flanges 1022 on the different sides of the support piece 102, the connecting area of the support piece 102 and the inner plate 101 can be effectively increased, and the connecting strength of the support piece 102 and the inner plate 101 can be improved, and the structural strength of the support column assembly 100 can be improved.

[0056] Optionally, the third flange 1022 is bonded with the reinforcing plate.

[0057] For example, the third flange 1022 is bonded with the reinforcing plate by structural adhesive.

[0058] Optionally, the support piece 102 is stamped and formed.

[0059] Optionally, the retractor mounting 2 has at least one fourth flange 2021, the fourth flange 2021 is connected with the inner plate 101, the fourth flange 2021 and the second flange 2011 are arranged on different sides of the retractor mounting 2, the second flange 2011 is arranged in a direction away from the fourth flange 2021, and the fourth flange 2021 is arranged in a direction away from the second flange 2011.

[0060] For example, as shown in the figures, Figure 7 the second flange 2011 is arranged in a direction away from the fourth flange 2021, and the fourth flange 2021 is arranged in a direction away from the second flange 2011. The number of the fourth flange 2021 is two, and the two fourth flanges 2021 and the two second flanges 2011 are respectively arranged on the four different sides of the retractor mounting 2. Specifically, one second flange 2011 and one fourth flange 2021 are arranged opposite to each other along the height direction of the inner plate 101, and the other second flange 2011 and the other fourth flange 2021 are arranged opposite to each other along the width direction of the inner plate 101.

[0061] On the one hand, by connecting the fourth flange 2021 with the inner plate 101, the connecting strength of the retractor mounting 2 and the inner plate 101 can be improved, which is beneficial to further reduce the risk of safety belt retractor pull-off failure and improve the safety of the vehicle with the support column assembly 100. On the other hand, the second flange 2011 is arranged in a direction away from the fourth flange 2021, and the fourth flange 2021 is arranged in a direction away from the second flange 2011, which facilitates the connection of the second flange 2011 and the inner plate 101 and the connection of the fourth flange 2021 and the inner plate 101.

[0062] Optionally, the number of the fourth flange 2021 is a plurality, and the plurality of fourth flanges 2021 are arranged on different sides of the retractor mounting 2.

[0063] For example, such as Figure 7 As shown, the outer periphery of the retractor mounting part 2 is generally rectangular, and there are two fourth flanges 2021. The two fourth flanges 2021 and the two second flanges 2011 are respectively provided on the four different sides of the retractor mounting part 2.

[0064] By placing multiple fourth flanges 2021 on different sides of the retractor mounting member 2, the connection area between the retractor mounting member 2 and the inner panel 101 can be effectively increased, further improving the connection strength between the retractor mounting member 2 and the inner panel 101. This helps to further reduce the risk of seat belt retractor pull-out failure and improve the safety of vehicles with the support column assembly 100.

[0065] Optionally, the fourth flange 2021 is welded to the inner plate 101.

[0066] For example, each fourth flange 2021 is welded to the inner plate 101 by at least one spot weld.

[0067] Therefore, welding the fourth flange 2021 to the inner panel 101 improves the connection strength between the fourth flange 2021 and the inner panel 101, which helps to further reduce the risk of seat belt retractor pull-out failure and improve the safety of vehicles with this support column assembly 100.

[0068] In related technologies, the first-order installation modal value of the retractor mounting component (referring to the modal analysis value of the retractor mounting component in the body-in-white state with the retractor) is 26Hz. When excited by the road surface (the excitation is mainly concentrated in 10-50Hz), it is prone to resonance, which causes large vibrations and abnormal noises, resulting in a very poor driving experience for consumers.

[0069] Optionally, the retractor mounting component 2 is constructed as a box-shaped structure.

[0070] The box-shaped and flat-shaped structures can effectively improve the first-order mounting mode of the retractor mount 2. For example, the first-order mounting mode of the retractor mount 2 is improved to 53Hz, thereby avoiding abnormal noise problems and bringing consumers a good driving experience.

[0071] Optionally, the retractor mounting component 2 includes a first plate 201 and a second plate 202, a second flange 2011 is disposed on the first plate 201, and a fourth flange 2021 is disposed on the second plate 202. The first plate 201 has a fifth flange 2012, and the second plate 202 has a sixth flange 2022, with the fifth flange 2012 and the sixth flange 2022 connected together.

[0072] It can be understood that at least one of the first plate body 201 and the second plate body 202 is provided with a mounting hole for mounting a retractor of a safety belt. By providing the retractor mounting member 2 as a structure including the first plate body 201 and the second plate body 202, it is convenient to provide a mounting hole on at least one of the first plate body 201 and the second plate body 202, thereby facilitating the design and manufacture of the retractor mounting member 2.

[0073] In addition, as shown in Figure 8 and Figure 9 The fifth flange 2012 and the sixth flange 2022 are connected to realize the connection of the first plate body 201 and the second plate body 202, which is conducive to improving the connection strength of the first plate body 201 and the second plate body 202. Thus, it is conducive to further reducing the risk of safety belt retractor pull-off failure and improving the safety of the vehicle with the support column assembly 100.

[0074] Optionally, the fifth flange 2012 and the sixth flange 2022 overlap in the thickness direction of the inner plate 101.

[0075] For example, by overlapping the fifth flange 2012 and the sixth flange 2022 in the thickness direction of the inner plate 101, the connection area of the first plate body 201 and the second plate body 202 can be effectively improved, thereby further improving the connection strength of the first plate body 201 and the second plate body 202.

[0076] Optionally, the fifth flange 2012 and the sixth flange 2022 are welded.

[0077] For example, the fifth flange 2012 and the sixth flange 2022 are welded by five spot welds.

[0078] In this way, the connection strength of the first plate body 201 and the second plate body 202 is better, which is conducive to further reducing the risk of safety belt retractor pull-off failure and improving the safety of the vehicle with the support column assembly 100.

[0079] The assembly process of the support column assembly 100 of the embodiment of the application is as follows:

[0080] The first plate body 201 and the second plate body 202 are connected together by 5 two-layer spot welds to form a box-shaped retractor mounting member 2, which can effectively improve the first-order installation mode (the first-order installation mode is improved to 53HZ), thereby avoiding resonance noise problems.

[0081] The support member 102 is first connected to the inner plate 101 by 3 two-layer spot welds to form an inner plate assembly; then the retractor mounting member 2 is connected to the inner plate assembly, and Figure 3It can be seen that the second plate body 202 and the support 102 are effectively overlapped, and the second plate body 202, the inner plate 101 and the support 102 are connected by a three-layer spot welding at the overlapping position. The retractor mounting member 2 and the support 102 form effective support in the thickness direction of the inner plate 101, which can greatly improve the connection strength, thereby avoiding the risk of safety belt retractor pull-off failure.

[0082] The vehicle of the embodiment of the present application comprises the support column assembly 100 of any of the above embodiments.

[0083] The support column body 1 can be a C column or a D column, and the retractor mounting member 2 can be used to mount a double-row safety belt retractor or a three-row safety belt retractor.
