Description

A kind of body hinge mounting points is strengthened structure
Technical field
The utility model relates to automobile manufacturing field, refers to especially a kind of body hinge mounting points reinforcement structure.
Background technology
In recent years, along with the aggravation of automobile market competition, each automobile production producer all pays much attention to the exploitation of vehicle performance, and wherein the correlated performance of car door is one of car load important performance.How to improve car door performance by structure design and become the problem that each manufacturer is generally concerned about.
Existing passenger car, for realizing car door packing, improving hinge strength, generally adopts formed steel construction body hinge.Formed steel construction hinge is vehicle door side mounting points than punching structure body hinge few, this kind of hinge requires higher to the strength and stiffness of hinge strengthening structure, often there is Rigidity and strength deficiency, cause car door to sink or mounting points cracking, and then cause leak out, the problem such as roof leaking and the reduction of NVH performance, affect car load riding comfort and safety.Generally ensure mounting points intensity by increasing material thickness and size for the problems referred to above, so not only increased development cost and complete vehicle weight, and reduced the competitive advantage of car load.So need to find a kind of method that can improve performance, weight reduction, reduce costs, simplify production technology and raising car load competitive advantage.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of body hinge mounting points and strengthens structure, to solve the problem of existing body hinge mounting points Rigidity and strength deficiency.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of body hinge mounting points to strengthen structure, be used for connecting car door and car body, described hinge mounting points is strengthened structure and is comprised inner plate of car door, door skin, hinge mounting plate and hinge stiffening plate, and the hinge mounting plate of described hinge strengthening structure and described hinge stiffening plate pass through CO 2protection weldering connects; described hinge stiffening plate is connected by spot welding with inner plate of car door; institute's inner plate of car door is connected by bound edge with door skin, and described hinge mounting plate is provided with screwed hole, and described hinge is connected with described hinge mounting plate with described screwed hole by bolt.
Wherein, the material of described hinge mounting plate is 8mm steel plate.
Wherein, described hinge mounting plate is provided with the locating hole welding with described hinge stiffening plate.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, by adopting CO 2protection is welded with effect decomposes to surrounding stressed mounting points, reduces mounting points stress and concentrates, and improves mounting points reliability; Screwed hole has been simplified production technology, has improved precision and the intensity of mounting points, and has improved sealing and the safety of car load.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As Fig. 1, Fig. 3, shown in Fig. 4, the utility model embodiment is for the problem of existing body hinge mounting points Rigidity and strength deficiency, provide a kind of body hinge mounting points to strengthen structure, be used for connecting car door and car body, described hinge mounting points is strengthened structure and is comprised inner plate of car door 6, door skin 8, hinge 9, hinge mounting plate 1 and hinge stiffening plate 4, described hinge 9 is L-type, described hinge 9 one end are fixed on inner plate of car door 6 by bolt 10 and described hinge mounting plate 1, described hinge mounting plate 1 welds with described hinge stiffening plate 4, described hinge stiffening plate 4 one end and described inner plate of car door 6 weld, described hinge 1 other end is connected with car body, described hinge mounting plate 1 protects weldering 7 to be connected with described hinge stiffening plate 4 by CO2, described hinge mounting plate 1 is provided with screwed hole 3, described hinge 9 is connected with described hinge mounting plate 1 with screwed hole 3 by bolt 10.
Further, described hinge 9 is L-type, and for connecting car door and car body, described hinge 9 one end are provided with screw and are connected with car door, and the other end is provided with the collar and car body connects, and car door is stabilized on car body.
Wherein, as shown in Figure 2, the material of described hinge mounting plate 1 is 8mm steel plate, is provided with the locating hole 2 welding with described hinge stiffening plate 4, and described hinge mounting plate 1 passes through CO with described hinge stiffening plate 4 2protection weldering 7 connects, and effectively local stress relieving is concentrated the distortion and the cracking that cause.
Further, described hinge stiffening plate 4 is connected with described inner plate of car door 6 by spot welding 5, and welding procedure is simple and firmly, described inner plate of car door 6 is connected with described door skin 8 bound edges, is conducive to improve the sealing of Integral automobile.
Wherein, described hinge mounting plate 1 is provided with the screwed hole 3 suitable with described bolt 10, with the alternative original project-welding nut of screwed hole 3, simplify production technology, the screwed hole 3 ratio of precision project-welding nuts of processing are higher, are conducive to improve car door assembly precision, improved intensity and the stiffness installed simultaneously.
