技术领域Technical Field
本发明涉及汽车转向支撑领域，具体涉及一种汽车的转向支撑安装的加强结构。The invention relates to the field of automobile steering support, and in particular to a reinforcing structure for installing an automobile steering support.
背景技术Background Art
支撑柱作为用于支撑转向系统、仪表板等部件的刚性构件，被安装在车身宽度方向上，其两端安装在车身的左、右侧内板上。支撑柱的固定位置强度和定位的准确度，直接影响整个转向系统和仪表台的稳定性和整车的NVH性能，NVH指的是Noise噪音、Vibration振动和Harshness声振粗糙度。现有的支撑柱安装方式，是采用L形的支架与车身侧内板焊接相连，然后在L形的支架上开安装孔与安装过孔，再与支撑柱相连接，这种安装方式，因L形的支架强度难以保证，故支撑柱安装后，会产生变形，使仪表板与周边匹配间隙变大，在车辆行驶中，产生噪音影响仪表台的稳定性和整车NVH性。并且这种单层定位孔，在装配时也会出现定位旋转，装配困难，精度差等问题。The support column is a rigid component used to support the steering system, instrument panel and other components. It is installed in the width direction of the vehicle body, and its two ends are installed on the left and right inner panels of the vehicle body. The fixed position strength and positioning accuracy of the support column directly affect the stability of the entire steering system and instrument panel and the NVH performance of the vehicle. NVH refers to noise, vibration and harshness. The existing support column installation method is to use an L-shaped bracket to weld and connect it to the side inner panel of the vehicle body, and then open mounting holes and mounting holes on the L-shaped bracket, and then connect it to the support column. This installation method is difficult to ensure the strength of the L-shaped bracket. Therefore, after the support column is installed, it will be deformed, which will increase the matching gap between the instrument panel and the surrounding area. During the driving of the vehicle, noise will be generated, affecting the stability of the instrument panel and the NVH performance of the vehicle. In addition, this single-layer positioning hole will also cause problems such as positioning rotation, assembly difficulty, and poor precision during assembly.

具体实施方式DETAILED DESCRIPTION
下面结合附图，对本发明作详细的说明。The present invention will be described in detail below in conjunction with the accompanying drawings.
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
实施例1Example 1
如图1-2，支撑外板1上有导向孔，导向孔的一侧布置有导向凸台9，导向凸台9的内圆与导向孔的半径相同且同心，支撑外板1上还有卷边10，支撑内板2上也具有卷边、导向孔和导向凸台。如图3-4，安装板3焊接安装在车身侧内板4上，支撑内板2的卷边贴合住支撑外板1的卷边，然后焊接在一起形成一个盒体，然后再将整个盒体通过卷边焊接在车身侧内板4上。如图5-6，定位销6焊接在支撑座5上，通过A、B两处的孔用螺栓将支撑座5安装在安装板3上。如图7，定位销6依次穿过支撑内板2的导向孔和支撑外板的导向孔，支撑柱8插入支撑座5的支撑孔中，支板7的一端顶住支撑柱8的D处，另一端固定在车声内板上，车身内板没在图中画出但不影响对本发明的理解；支撑座5上的凸边顶住支撑柱8的C处。As shown in Figure 1-2, there is a guide hole on the support outer plate 1, and a guide boss 9 is arranged on one side of the guide hole. The inner circle of the guide boss 9 is the same as the radius of the guide hole and is concentric. There is also a curling edge 10 on the support outer plate 1, and the support inner plate 2 also has a curling edge, a guide hole and a guide boss. As shown in Figure 3-4, the mounting plate 3 is welded and installed on the body side inner plate 4, and the curling edge of the support inner plate 2 fits the curling edge of the support outer plate 1, and then welded together to form a box body, and then the entire box body is welded to the body side inner plate 4 through the curling edge. As shown in Figure 5-6, the positioning pin 6 is welded to the support seat 5, and the support seat 5 is installed on the mounting plate 3 with bolts through the holes at A and B. As shown in Figure 7, the positioning pin 6 passes through the guide hole of the support inner plate 2 and the guide hole of the support outer plate in turn, the support column 8 is inserted into the support hole of the support seat 5, one end of the support plate 7 presses against the D of the support column 8, and the other end is fixed to the inner plate of the vehicle body. The inner plate of the vehicle body is not drawn in the figure but it does not affect the understanding of the present invention; the convex edge on the support seat 5 presses against the C of the support column 8.
装配时，支撑外板1、支撑内板2和安装板3已经焊接在车身侧内板4上形成一个整体，只需首先将支撑柱8插入支撑座5的支撑孔中，将定位销6穿过支撑内板2和支撑外板1的定位孔；然后，用螺栓将支撑座5固定在安装板3上，最后安装支板7，使支板7一端顶住支撑柱8。这种结构使得装配非常简单方便，同时由于支撑柱8的C、D处受到了支撑，使得支撑柱8的刚性变强。由于仪表板和转向支撑系统安装在支撑柱8上，支撑柱8的刚性保证了仪表板与周边匹配间隙不会过大，同时保证了装配的精度。During assembly, the supporting outer panel 1, the supporting inner panel 2 and the mounting plate 3 have been welded to the vehicle body side inner panel 4 to form a whole. You only need to first insert the supporting column 8 into the supporting hole of the supporting seat 5, and pass the positioning pin 6 through the positioning holes of the supporting inner panel 2 and the supporting outer panel 1; then, fix the supporting seat 5 to the mounting plate 3 with bolts, and finally install the support plate 7 so that one end of the support plate 7 supports the supporting column 8. This structure makes assembly very simple and convenient. At the same time, since the C and D points of the supporting column 8 are supported, the rigidity of the supporting column 8 is strengthened. Since the instrument panel and the steering support system are installed on the supporting column 8, the rigidity of the supporting column 8 ensures that the matching gap between the instrument panel and the surrounding area will not be too large, and at the same time ensures the assembly accuracy.
工作时，由支撑内板2和支撑外板1构成的盒体具有一定的柔性，支撑座5连接在安装板3上的方式也具有一定的柔性，表现为支撑柱8与车身内侧板的连接为柔性连接，这种柔性连接通过摩擦吸振的方式将车身的振动对支撑柱8的影响降低。本发明由于具有刚性适中的独特结构，所以表现出了优秀的装配性能和NVH性能。When working, the box body composed of the inner support plate 2 and the outer support plate 1 has a certain flexibility, and the way the support seat 5 is connected to the mounting plate 3 also has a certain flexibility, which is manifested as a flexible connection between the support column 8 and the inner side plate of the vehicle body. This flexible connection reduces the influence of the vibration of the vehicle body on the support column 8 by friction vibration absorption. The present invention has a unique structure with moderate rigidity, so it shows excellent assembly performance and NVH performance.
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
