技术领域technical field
本发明涉及汽车的零部件，更具体的说涉及一种汽车后保险杠及后碰撞横梁的安装支架。The invention relates to parts of automobiles, and more specifically relates to a rear bumper and a mounting bracket for a rear collision beam of an automobile.
背景技术Background technique
随着汽车工业的不断发展，对轿车各种安装支架的集成性、安装可靠性方面，成本方面的设计要求越来越高。现有的后保险杠安装支架如图4所示，现有的后碰撞横梁安装支架如图5所示，其两者之间是相互独立的支架，这样不利于零件的管控，也会一定程度地增加零件成本。此外，现有的后保险杠安装支架7，其Z向和X向（即竖直方向和水平方向）的强度较差，汽车行驶过程中，保险杠容易攒动，甚至会产生异响。现有的后碰撞横梁安装支架8在设计过程中没有考虑X方向的受力情况，在发生碰撞时，由于其强度较差，容易造成严重变形，增加维修成本。后碰撞横梁采用焊接螺母安装后碰撞横梁安装支架上，该安装方式，不利于后碰撞横梁的快速定位，影响工作人员的安装效率。With the continuous development of the automobile industry, the design requirements for the integration, installation reliability and cost of various mounting brackets for cars are getting higher and higher. The existing rear bumper mounting bracket is shown in Figure 4, and the existing rear collision beam mounting bracket is shown in Figure 5, and the two are mutually independent brackets, which is not conducive to the control of parts, and will also cause damage to a certain extent. increase the cost of parts. In addition, the existing rear bumper mounting bracket 7 has poor strength in the Z and X directions (that is, the vertical direction and the horizontal direction), and the bumper is easy to move when the car is running, and even produces abnormal noise. The existing rear collision beam mounting bracket 8 does not consider the stress in the X direction during the design process. When a collision occurs, due to its poor strength, it is easy to cause serious deformation and increase maintenance costs. The rear collision beam is installed on the rear collision beam installation bracket with welded nuts. This installation method is not conducive to the rapid positioning of the rear collision beam and affects the installation efficiency of the staff.

The rear bumper and the rear collision beam of the automobile are installed on the vehicle body through the two mounting brackets .
所述竖直钣金件的左右两侧及下端和水平钣金件的左右侧均设有翻边，在竖直钣金件上沿纵向设有第一加强筋，该第一加强筋的下端位于竖直钣金件与水平钣金件的连接处，在竖直钣金件上沿横向设有第二加强筋。The left and right sides and lower ends of the vertical sheet metal parts and the left and right sides of the horizontal sheet metal parts are all provided with flanges, and the vertical sheet metal parts are provided with first reinforcing ribs in the longitudinal direction, and the lower ends of the first reinforcing ribs are Located at the junction of the vertical sheet metal part and the horizontal sheet metal part, the vertical sheet metal part is provided with a second reinforcing rib along the transverse direction.
本发明所述汽车后保险杠及后碰撞横梁的安装支架，具有以下优点：首先，将后保险杠安装支架和后碰撞横梁安装支架集成在同一安装支架上，同时满足了汽车后保险杠及后碰撞横梁的安装，简化了安装支架的结构，降低了生产成本，实现了车身轻量化的设计；其次，该安装支架采用后碰撞横梁安装螺栓的安装方式来安装后碰撞横梁，便于在安装时的快速定位，方便了安装时的操作；最后，在安装支架上设有翻边及加强筋，增加了安装支架的刚强度，特别是Z向和X向的强度，保证了汽车后保险杠的可靠安装，避免了保险杠攒动和产生异响，当发生追尾事故时，该安装支架不会随着后碰撞横梁吸能发生变形而变形，降低了安装支架的维修成本。The mounting bracket of the rear bumper and the rear collision beam of the automobile according to the present invention has the following advantages: firstly, the mounting bracket of the rear bumper and the mounting bracket of the rear collision beam are integrated on the same mounting bracket, and the rear bumper and the rear bumper of the automobile are satisfied at the same time. The installation of the collision beam simplifies the structure of the installation bracket, reduces the production cost, and realizes the lightweight design of the vehicle body; secondly, the installation bracket adopts the installation method of the installation bolt of the rear collision beam to install the rear collision beam, which is convenient for installation. Quick positioning facilitates the operation during installation; finally, there are flanges and ribs on the mounting bracket, which increases the rigidity of the mounting bracket, especially the strength in the Z and X directions, ensuring the reliability of the rear bumper of the car The installation avoids bumper bumps and abnormal noises. When a rear-end collision occurs, the mounting bracket will not be deformed as the rear collision beam absorbs energy, which reduces the maintenance cost of the mounting bracket.
