Description
技术领域technical field
本实用新型属于车身结构设计的技术领域，更具体的说，本实用新型涉及一种能够有效加强汽车碰撞安全的前轮罩上加强梁的连接结构。The utility model belongs to the technical field of vehicle body structure design, more specifically, the utility model relates to a connection structure of a reinforcing beam on a front wheel cover that can effectively enhance the collision safety of an automobile.
背景技术Background technique
如图1所示，其示出了前轮罩上加强梁在车身上的位置，前轮罩上加强梁是车身受力时是一个重要的受力部件和传力路径，如果此部件不能把车辆前方碰撞时所受的力向后传递，会加大对乘员的伤害。如图2～4所示，现有技术中前轮罩上加强梁1与侧围外板2通过CO2焊接，侧围外板不与A柱加强板3和A柱支撑板4贴合。在车身受到碰撞时，车身受到的力通过前轮罩上加强梁传递给侧围外板，但因为侧围外板料厚比较薄，且材料选用的是普通钢材，材料的屈服强度和抗拉强度较低，在承受大的受力的情况下，容易撕裂外板，前轮罩上加强梁结构不能很好的把力传递给侧围总成，不能发挥前轮罩上加强梁的传力结构，碰撞性能较差。As shown in Figure 1, it shows the position of the reinforcement beam on the front wheel house on the vehicle body. The reinforcement beam on the front wheel house is an important force-bearing part and force transmission path when the body is stressed. The force received when the vehicle collides with the front is transmitted backwards, which will increase the damage to the occupants. As shown in Figures 2-4, in the prior art, the reinforcement beam 1 on the front wheel house and the side wall outer panel 2 are welded by CO2 , and the side wall outer panel is not bonded to the A-pillar reinforcement plate 3 and the A-pillar support plate 4. When the body is collided, the force received by the body is transmitted to the side panel through the reinforcement beam on the front wheel house. However, because the thickness of the side panel is relatively thin, and the material is ordinary steel, the yield strength and tensile strength of the material The strength is low, and it is easy to tear the outer panel under the condition of bearing a large force. The structure of the reinforcement beam on the front wheel house cannot transmit the force to the side wall assembly well, and the transmission of the reinforcement beam on the front wheel house cannot be exerted. Force structure, poor crash performance.

具体实施方式Detailed ways
以下将结合具体实施例对本实用新型所述的前轮罩上加强梁的连接结构做进一步的阐述，以帮助本领域的技术人员对本实用新型的实用新型构思、技术方案有更完整、准确和深入的理解。The connecting structure of the reinforcement beam on the front wheel house described in the present invention will be further elaborated below in conjunction with specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the present invention understanding.
实施例1Example 1
如图5～6所示，本实施例所述的前轮罩上加强梁的连接结构，包括前轮罩上加强梁1，以及依次贴合在所述前轮罩上加强梁上的侧围外板2、A柱加强件3和A柱支撑板4；并且所述前轮罩上加强梁1、侧围外板2、A柱加强件3和A柱支撑板4通过依次穿过它们的螺栓11连接在一起并通过螺栓11与凸焊螺母12紧固。在本实施例的连接结构中前轮罩上加强梁是车身在碰撞时一个重要的力的传递路径，前轮罩上加强梁通过螺栓与侧围外板，A柱加强件，A柱支撑板连接，能够使这些零件共同受力，能减小A柱的后退量。在本实施例的连接结构中通过螺栓连接形成了一个整体，所以能承受比较大的力，分散了车身的载荷，所以能减小其他受力部位的料厚，减轻车身重量，降低车身成本。此结构还能够提高前轮罩上加强梁与侧围连接处的刚性，能提升车身的弯曲与扭转刚性，增加操作稳定性减小振动噪音。螺栓连接是一个稳定的高强度的连接结构，能够防止前轮罩上加强梁和侧围连接处的疲劳破坏。现有技术中采用CO2焊接时容易损伤侧围外板，而本实施例的连接结构能避免CO2焊接，从而可以降低侧围外板的厚度，并且提高连接效率。As shown in Figures 5 to 6, the connection structure of the reinforcement beam on the front wheel house described in this embodiment includes the reinforcement beam 1 on the front wheel house, and the side walls that are sequentially attached to the reinforcement beam on the front wheel house the outer panel 2, the A-pillar reinforcement 3 and the A-pillar support plate 4; Bolts 11 are connected together and fastened by bolts 11 and projection welding nuts 12 . In the connection structure of this embodiment, the reinforcing beam on the front wheel house is an important force transmission path when the vehicle body collides. The reinforcing beam on the front wheel house passes through the bolts and the side panel, the A-pillar reinforcement, and the A-pillar support plate. The connection can make these parts bear the force together, and can reduce the amount of retreat of the A-pillar. In the connection structure of this embodiment, a whole is formed by bolt connection, so it can bear a relatively large force and disperse the load of the vehicle body, so the material thickness of other stress-bearing parts can be reduced, the weight of the vehicle body can be reduced, and the cost of the vehicle body can be reduced. This structure can also improve the rigidity of the connection between the reinforcing beam on the front wheel house and the side wall, improve the bending and torsional rigidity of the vehicle body, increase the operating stability and reduce vibration and noise. The bolt connection is a stable high-strength connection structure that can prevent fatigue damage at the connection between the reinforcement beam on the front wheel house and the side wall. In the prior art, CO 2 welding is used to easily damage the side wall outer plate, but the connection structure of this embodiment can avoid CO 2 welding, thereby reducing the thickness of the side wall outer plate and improving connection efficiency.
对于本领域的普通技术人员而言，具体实施例只是对本实用新型进行了示例性描述，显然本实用新型具体实现并不受上述方式的限制，只要采用了本实用新型的方法构思和技术方案进行的各种非实质性的改进，或未经改进将本实用新型的构思和技术方案直接应用于其它场合的，均在本实用新型的保护范围之内。For those of ordinary skill in the art, the specific embodiment is only an exemplary description of the utility model. Obviously, the specific implementation of the utility model is not limited by the above-mentioned method, as long as the method concept and technical solution of the utility model are adopted to carry out Various insubstantial improvements, or directly applying the concept and technical solutions of the utility model to other occasions without improvement, are all within the protection scope of the utility model.
