[0028] Embodiment 1

[0029] As Figure 1 And Figure 2 As shown, this embodiment provides an automotive sill support member 1, which is installed on the outer side of the sill and includes: a fixed plate 13 and a support plate formed integrally; the support plate includes a first support plate 11 and a second support plate 12 arranged on both sides of the fixed plate 12 along the length direction and at a certain angle with the fixed plate 13. On one side in the width direction of the first support plate 11, there is a first connecting plate 14 extending towards the second support plate 12. On one side in the width direction of the second support plate 12, there is a second connecting plate 15 extending towards the first support plate 11. The first connecting plate 14 and the second connecting plate 15 are fixedly connected. It should be noted that in this application, the angle range between the first support plate 11 and the fixed plate 13 is 45° - 90°, and the angle range between the second support plate 12 and the fixed plate 13 is 45° - 90°, such as 45°, 60° or 75°. It is not limited herein, and the specific set angle is selected according to actual requirements.

[0030] As Figure 3 As shown, the automotive sill includes a sill middle plate 21, a sill upper plate 22 and a sill lower plate 23. The sill upper plate 22 and the sill lower plate 23 are respectively located on the upper and lower sides of the sill middle plate 21. The fixed plate 13 is fixed to the sill lower plate 23. The first connecting plate 14 and the second connecting plate 15 are located outside the sill middle plate 21. On the side of the first support plate 11 and the second support plate 12 opposite to the first connecting plate 14 and the second connecting plate 15, they abut against the sill middle plate 21. The tops of the first support plate 11 and the second support plate 12 abut against the lower surface of the sill upper plate 22. In this application, the integral structure of the support member 1 ensures the strength of the support member 1. The first connecting plate 14 and the second connecting plate 15 disperse and transfer the absorbed impact force to the sill middle plate 21 through the first support plate 11 and the second support plate 12. When the sill upper plate 22 is impacted by an external force, it is transmitted to the fixed plate 13 through the first support plate 11 and the second support plate 12, and then the fixed plate 13 squeezes the sill lower plate 23. The obliquely arranged first support plate 11 and second support plate 12 can resolve the impact force received by the sill upper plate 22, further ensuring the support strength of the support member 1 for the sill; the fixed connection of the first connecting plate 14 and the second connecting plate 15 is used to absorb the resolved force of the impact on the sill upper plate 22, avoid damage caused by the extrusion of the sill upper plate 22, and ensure the strength of the support member 1.

[0031] Furthermore, as Figure 1 And Figure 2As shown in the figure, in a specific example provided by this embodiment, the fixing plate 13 is provided with two mounting holes 131, and the fixing plate 13 is fixed on the vehicle sill through bolts and nuts. The present application does not limit the number of mounting holes 131 on the fixing plate 13. The fixing plate 13 is provided with at least one mounting hole 131, and the specific number of the mounting holes 131 is determined according to the design strength.

[0032] In a specific example provided by this embodiment, the two sides of the fixing plate 13 are respectively provided with a first arc panel 132 and a second arc panel 133. The first arc panel 132 is located between the fixing plate 13 and the first support plate 11, and the second arc panel 133 is located between the fixing plate 13 and the second support plate 12. The first arc panel 132 and the second arc panel 133 are used to improve the connection strength between the fixing plate 13 and the first support plate 11 and the second support plate 12, and further ensure the strength of the support member 1.

[0033] Furthermore, in this embodiment, there is a first arc transition section 141 between the first connecting plate 14 and the first support plate 11, and a second arc transition section 151 between the second connecting plate 15 and the second support plate 12. During actual use, the first arc transition section 141 can improve the connection strength between the first connecting plate 14 and the first support plate 11, and the second arc transition section 151 can improve the connection strength between the second connecting plate 15 and the second support plate 12, so as to improve the compressive strength of the first connecting plate 14 and the second connecting plate 15, and further improve the overall strength of the support member 1.

[0034] In a specific example provided by this embodiment, the top and bottom of the first support plate 11 are respectively provided with a first upper inclined side 115 and a first lower inclined side 117 that are connected to the upper and lower sides of the first connecting plate 14; the top and bottom of the second support plate 12 are respectively provided with a second upper inclined side 125 and a second lower inclined side 127 that are connected to the upper and lower sides of the second connecting plate 15. Among them, the roots of the first upper inclined side 115 and the first lower inclined side 117 are respectively provided with a first upper arc side 116 and a first lower arc side 118, and the roots of the second upper inclined side 125 and the second lower inclined side 127 are respectively provided with a second upper arc side 126 and a second lower arc side 128.

[0035] During actual use, when the first connecting plate 14 and the second connecting plate 15 are impacted, the first connecting plate 14 transmits the impact to the first support plate 11 through the first arc transition section 141. The first upper inclined side 115 cooperates with the first upper arc side 116, and the first lower inclined side 117 cooperates with the first lower arc side 118 to improve the strength of the first support plate 11. The impact received by the second connecting plate 15 is transmitted to the second support plate 12 through the second arc transition section 151. The second upper inclined side 125 cooperates with the second upper arc side 126, and the second lower inclined side 127 cooperates with the second lower arc side 128 to improve the strength of the second support plate 12. Specifically, in this embodiment, the inclination ranges of the first upper inclined side 115, the first lower inclined side 117, the second upper inclined side 125, and the second lower inclined side 127 are between 45° and 90° (including 45° but not including 90°). The inclination angles of the first upper inclined side 115 and the second upper inclined side 125 are the same, the inclination angles of the first lower inclined side 117 and the second lower inclined side 127 are the same, and the inclination angles of the first upper inclined side 115 and the second upper inclined side 127 are respectively greater than the angles of the first lower inclined side 117 and the second lower inclined side. The specific angles are selected according to the actual design and are not limited herein.

[0036] The inclination angle of the first upper inclined side 115 is greater than the inclination angle of the first lower inclined side 117, and the inclination angle of the second upper inclined side 125 is greater than the inclination angle of the second lower inclined side 127.

[0037] In a specific example provided in this embodiment, three first positioning holes 142 are provided on the first connecting plate 14, and three second positioning holes 152 are provided on the second connecting plate 15. The first positioning holes 142 and the second positioning holes 152 correspond to each other one by one. During actual manufacturing, the first connecting plate 14 and the second connecting plate 15 are arranged in an interleaved manner, and a fixing column is inserted through the corresponding first positioning hole 142 and second positioning hole 152. The fixing column is welded to the first connecting plate 14 and the second connecting plate 15 to realize the fixed connection between the first connecting plate 14 and the second connecting plate 15. The number of the first positioning holes 142 and the second positioning holes 152 is not limited in this application. At least one first positioning hole 142 is provided on the first connecting plate 14; at least one second positioning hole 152 corresponding to the first positioning hole 142 is provided on the second connecting plate 15. In this embodiment, the first connecting plate 14 and the second connecting plate 15 are arranged in an interleaved manner, and the fixing column welds the first connecting plate 14 and the second connecting plate 15 together to ensure the anti-extrusion strength of the first support plate 11 and the second support plate 12. In another embodiment, the first connecting plate 14 and the second connecting plate 15 are arranged in an interleaved manner, and the edge of the first connecting plate 14 is welded to the edge of the second connecting plate 15. The fixing method of the first connecting plate 14 and the second connecting plate 15 is not limited in this application, and the fixed connection can be actually made according to requirements.

[0038] In a specific example provided in this embodiment, at least one first pressure-reducing plate 111 away from the second support plate 12 is provided on one side of the first support plate 11 relative to the first connecting plate 14; at least one second pressure-reducing plate 121 away from the first support plate 11 is provided on one side of the second support plate 12 relative to the second connecting plate 15. In this embodiment, the number of the first pressure-reducing plate 111 and the second pressure-reducing plate 121 is two.

[0039] During actual application, the first connecting plate 14 transfers the external force to the first pressure-reducing plate 111. The first pressure-reducing plate 111 increases the stress area between the first support plate 11 and the middle plate 21 of the threshold, and reduces the pressure of the first support plate 11 on the middle plate 21 of the threshold. The second support plate 12 transfers the external force to the second pressure-reducing plate 121. The second pressure-reducing plate 121 increases the stress area between the second support plate 12 and the middle plate 21 of the threshold, and reduces the pressure of the second support plate 12 on the middle plate 21 of the threshold. The first pressure-reducing plate 111 and the second pressure-reducing plate 121 can ensure the support strength of the support member 1 and avoid damage to the middle plate 21 of the threshold caused by the support member 1 being squeezed by the force.

[0040] In a specific example provided in this embodiment, a first arc-shaped plate 112 is provided between the first pressure-reducing plate 111 and the first support plate 11; a second arc-shaped plate 122 is provided between the second pressure-reducing plate 121 and the second support plate 12. The first arc-shaped plate 112 is used to improve the compressive strength between the first pressure-reducing plate 111 and the first support plate 11, and the second arc-shaped plate 122 is used to improve the compressive strength between the second pressure-reducing plate 121 and the second support plate 12; the overall strength of the support member 1 is ensured during actual use. In other embodiments, a first reinforcing rib is provided between the first pressure-reducing plate 111 and the first support plate 11 to improve the compressive strength between the first pressure-reducing plate 111 and the first support plate 11, and a second reinforcing rib is provided between the second pressure-reducing plate 121 and the second support plate 12 to improve the compressive strength between the second pressure-reducing plate 121 and the second support plate 12. Thus, the specific structure of the present application for improving the compressive strength between the first pressure-reducing plate 111 and the first support plate 11, and between the second pressure-reducing plate 121 and the second support plate 12.

[0041] As Figures 1 to 3 shown, in a specific example provided in this embodiment, at least one first upper pressure-reducing plate 113 away from the second support plate 12 is provided on the top of the first support plate 11; at least one second upper pressure-reducing plate 123 away from the first support plate 11 is provided on the top of the second support plate 12.

The first upper arc-shaped plate 114 and the second upper arc-shaped plate 124 can further improve the overall strength of the support member 1.

[0043] In a specific example provided in this embodiment, a first weight-reducing hole 119 is provided on the first support plate 11; a second weight-reducing hole 129 is provided on the second support plate 12. Specifically, in this embodiment, the shapes of the first weight-reducing hole 119 and the second weight-reducing hole 129 are waist-shaped holes.
