Description
Technical Field
The utility model relates to a technical field of automobile design and manufacturing, more specifically say, the utility model relates to a door hinge mounting structure.
Background
In the prior art, the side wall structure is mostly matched with three-layer plates (a side wall outer plate, a reinforcing plate and a hinge nut plate), and all round holes are formed for matching. The joint area at the hinge installation position is large, so that the situation that electrophoresis liquid is difficult to enter and discharge is easy to occur at the joint surface position of a plate material during coating, the problem of poor paint film coverage is caused, and the corrosion resistance of a vehicle body is further influenced; when high-temperature baking finish is coated, the electrophoretic liquid which is not discharged generates high-temperature expansion overflow, so that the problem of electrophoretic liquid remaining marks at the outer plate of the side wall is caused, and the appearance quality is influenced.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned technical problem that exists among the prior art, the utility model aims to provide a door hinge mounting structure.
The utility model discloses a door hinge mounting structure, which comprises a side wall outer plate, a reinforcing plate and a hinge nut plate; the method is characterized in that: the side wall outer plate is provided with a side wall mounting surface, the side wall mounting surface is provided with a circular side wall mounting hole, the reinforcing plate is provided with a reinforcing plate mounting surface, the reinforcing plate mounting surface is provided with a key hole, and the key hole consists of a middle round hole corresponding to the circular side wall mounting hole and a long round hole which is tangent to the middle round hole and is positioned below the middle round hole; a motherboard mounting hole is formed in the hinge nut plate; the side wall mounting surface, the reinforcing plate mounting surface and the hinge nut plate are sequentially contacted, so that the side wall mounting hole, the middle round hole and the mother board mounting hole are correspondingly formed into mounting pore channels and welded and fixed to form a welding attachment surface, the lower part of the long round hole extends to the lower part of the welding attachment surface, and an electrophoresis gap channel is formed between the side wall outer plate and the hinge nut plate.
Wherein the diameter of the long round hole is smaller than that of the middle round hole.
Wherein, side wall mounting hole, key hole and mother board mounting hole are 2.
Compared with the prior art, the utility model discloses a door hinge mounting structure has following beneficial effect:
the utility model discloses a door hinge mounting structure can make things convenient for electrophoresis liquid to discharge into, not only can effectively prevent the electrophoresis liquid to rise the outward appearance problem that excessive leads to, also is favorable to improving automobile body corrosion resisting property simultaneously.

Detailed Description
The door hinge mounting structure of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 1 to 3, the present embodiment provides a door hinge mounting structure of a three-layer structure including a quarter outer panel 10, a reinforcement panel 20, and a hinge nut plate 30. The side wall outer plate 10 is provided with a side wall mounting surface 11, and the side wall mounting surface 11 is provided with a round side wall mounting hole 12. The reinforced plate 20 is provided with a reinforced plate mounting surface 21, the reinforced plate mounting surface 21 is provided with a key hole 22, the key hole 22 is composed of a middle round hole corresponding to the round side wall mounting hole 12 and a long round hole which is tangent to the middle round hole and is positioned below the middle round hole, and the diameter of the long round hole is smaller than that of the middle round hole. The hinge nut plate 30 is provided with a motherboard mounting hole 32. The side wall mounting surface 11, the reinforcing plate mounting surface 21 and the hinge nut plate 30 are sequentially contacted, so that the side wall mounting hole 12, the middle round hole and the mother plate mounting hole 32 are correspondingly formed into a mounting pore channel and form a welding attachment surface through welding fixation, the lower part of the long round hole extends to the lower part of the welding attachment surface, an electrophoresis gap channel 5 is formed between the side wall outer plate 10 and the hinge nut plate 30, and electrophoresis liquid can conveniently enter and be discharged. In the present embodiment, the number of the side wall mounting holes 12, the key hole 22, and the motherboard mounting hole 32 is preferably 2.
The door hinge mounting structure of the embodiment obviously improves the electrophoresis capability and the corrosion prevention grade of the automobile body metal plate under the conditions of not increasing the cost and not influencing the strength; and the problem of appearance quality caused by the expansion and overflow of the electrophoretic fluid in the high-temperature paint baking process can be prevented.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
