Description
[technical field]
The utility model is related to arrangements for automotive doors metal plate systems technology field, specifically a kind of anti-loosening gemel nutplate.
[background technology]
Inner plate of car door, hinge stiffening plate, hinge nut plate (portion are generally contained in vehicle door side hinge installation place, structure
Point vehicle contains) and nut, the nut is all generally project-welding nut, and be connected to by way of projection welding hinge stiffening plate or
On person's hinge nut plate.For the structure, generally there are following several respects not enough：
1) hinge installation bolt torque attenuation ratio is larger；
2) due to installing nut it is connected to by way of projection welding on hinge stiffening plate or nut installing plate, is there is
The risk of nut rosin joint, once nut rosin joint, when fastening bolt, nut will be from hinge mounting plate or nutplate
Come off so that body hinge can not be fixed, cause car door metal plate assembly to scrap；
3) stress concentration is easily produced in nut circumference, it will usually the flange face of nut is increased, but can still be existed
The phenomenon of stress concentration；
For it is above-mentioned it is several exist the problem of, different main engine plants combine technical characterstic, technological level and the supplier of itself
Ability level, the factor such as combination weight, cost, performance, which progressively develops, a set of one's own counte-rplan, cuts both ways.
Simultaneous automobile industry competition it is increasingly violent, how to effectively control cost also turn into design process in emphasis consider because
Element.Therefore, in line with how at utmost to enable parts hardware and software platform, generalization, at utmost reduction research and development and production cost,
Improving performance is simultaneously easy to quality control to turn into the problem of emphasis needs to consider in design process.
[utility model content]
The purpose of this utility model seeks to solve above-mentioned deficiency and provide a kind of anti-loosening gemel nutplate, can be effective
The decay of vehicle door side hinge installation bolt torque is reduced, stress concentration is effectively reduced at hinge mount point and to improve product reliable
Property.
Design to achieve the above object and form round platform on a kind of anti-loosening gemel nutplate, including plate body 1, the plate body 1
2, offer on the top end face of the round platform 2 and set on the screwed hole 3 through round platform 2 and plate body 1, the inwall of the screwed hole 3
There is internal thread, the root of the screwed hole 3 is circumferentially arranged with Hookean region 4, and the Hookean region 4 is used for the mistake fastened in bolt
Cheng Dangzhong prevents bolt looseness.
V-type neck 5 is formed on the plate body 1, the screwed hole 3 and Hookean region 4 are arranged in V-type neck 5.
The side of Hookean region 4 is set to plane on the plate body 1, and the plane is hinge stiffening plate binding face 6.
The periphery of plate body 1 is provided with the flange 7 outwards turned down.
The plate body 1 is using the cold pier shaping of high-strength alloy steel plate.
The wall thickness of the place round platform 2 of screwed hole 3 is more than the thickness of plate body 1.
The round platform 2 is in coniform.
Compared with the existing technology, structure is novel, simple, reasonable in design, and the anti-loosening gemel nutplate is used for the utility model
High-strength steel sheet applies cold pier technological forming, and tapping after shaping makes parts from threaded, so as to save projection welding process,
Avoid because the parts that project-welding nut rosin joint is brought are scrapped；Moreover, screwed hole root is Hookean region, the mistake fastened in bolt
Cheng Dangzhong, Hookean region can be produced elastic deformation by the tensile force of bolt fastening direction, and the elastic deformation can be prevented effectively
Bolt looseness, plays function equivalent to spring shim；Therefore, the anti-loosening gemel nutplate can effectively reduce the installation of vehicle door side hinge
Bolt Torque decays, and effectively stress concentration and lifts product reliability at reduction hinge mount point.

[embodiment]
Further explained below is made to the utility model below in conjunction with the accompanying drawings：
As shown in drawings, the utility model includes：Plate body 1, plate body 1 is using the cold pier shaping of high-strength alloy steel plate, plate body 1
On form round platform 2, round platform 2 offers the screwed hole 3 through round platform 2 and plate body 1, spiral shell in coniform on the top end face of round platform 2
Internal thread is provided with the inwall of pit 3, the wall thickness of the place round platform 2 of screwed hole 3 is more than the thickness of plate body 1, the root of screwed hole 3
Circumferentially arranged with Hookean region 4, Hookean region 4 is used to prevent elastic on bolt looseness, plate body 1 among the process of bolt fastening
The side in region 4 is set to plane, and plane is hinge stiffening plate binding face 6；V-type neck 5, screwed hole 3 are formed on the plate body 1
