Abstract
The utility model provides a U-shaped screw nut structure for a vehicle bumper. A first open pore with screw threads is arranged in the center of an upper portion of a screw nut (1). The U-shaped screw nut structure for the vehicle bumper is characterized in that one side of the upper portion of the screw nut is provided with a connecting portion (5) between the screw nut and a lower cover plate (4) of a bumper assembly, the screw nut (1) is integrated on the lower cover plate (4) of the bumper assembly through the connecting portion (5), and the lower cover plate (4) of the bumper assembly is provided with a second open pore corresponding to the first open pore in position. According to the U-shaped screw nut structure for the vehicle bumper, the integrated injection molding screw nut structure is simple in installation and accurate in positioning, increases integrated level of the bumper assembly, and reduces work load and complexity of installation of a supplier and an assembly shop. Besides, a pre-installation screw nut can not fall off from the bumper assembly in the process of transportation. Related plaques in a bumper system do not need additional connecting structures, so dies are simplified, integration of products is improved, and economical efficiency is good.
Description
Technical field
The utility model relates to a kind of nut structure, and more particularly, the utility model relates to a kind of U-nut structure that is used for bumper.
Background technique
In the prior art, the U-nut of plastics or metal is often used in the installation between the plastics plaque in the bumper system, for example, uses U-nut to connect Abdeckung Stossfaenger and bumper assembly lower cover plate.Fig. 1 is the schematic representation of U-nut; Fig. 2 connects the fundamental diagram of Abdeckung Stossfaenger 2 and bumper assembly lower cover plate 3 for using U-nut 1.As illustrated in fig. 1 and 2, U-nut has the upper and lower, and said upper and lower has a threaded perforate respectively.During use; Earlier U-nut 1 is installed on the Abdeckung Stossfaenger 2; Make the U-groove bevel of Abdeckung Stossfaenger 2 and nut 1 corresponding (Abdeckung Stossfaenger 2 is between said upper and lower); Then that fastening piece 4 is urgent through the bottom side of lower cover plate 3, promptly accomplish fastening between lower cover plate 3 and the Abdeckung Stossfaenger 2.This nut often need be installed by supplier or assembly workshop, and workload is bigger.In addition,, also can increase extra structure on the Abdeckung Stossfaenger, produce some unnecessary problem of appearance thus even be installed in advance in the bumper assembly; And the nut of installing in advance drops easily in transportation process and loses, and the product level of integration is poor, and is less economical.
The model utility content
For solving the problems referred to above of existing technology, the utility model proposes a kind of novel U-nut structure that is used for bumper.
The center on the top of the U-nut of the utility model has threaded first perforate; It is characterized in that; One side on said top have and bumper assembly lower cover plate between joint; Said nut is integrated on the said bumper assembly lower cover plate through said joint, and said bumper assembly lower cover plate has and corresponding second perforate in the position of said first perforate.
Preferably; The top of said nut is made up of the protuberance that a pedestal and makes progress; Said connection part is in a side of said pedestal, and said joint is the downward bending shapes of one 90 degree, and the lower end of said joint and said bumper assembly lower cover plate are integrated.
Preferably, the protuberance of said nut is positioned at the center of said pedestal, and said first perforate is arranged in said protuberance.
Preferably, said nut and said bumper assembly lower cover plate once injection moulding in a mould.
Preferably, said nut is identical with the material of said bumper assembly lower cover plate.
Especially, said nut and said bumper assembly lower cover plate are plastics or metallic material.
Because the U-nut of the utility model is integrated on the bumper assembly lower cover plate, therefore, the new U-nut that is used for bumper of the utility model has the following advantages:
1. simple, accurate positioning are installed, have increased the level of integration of bumper assembly, reduced the installation workload and the complexity of supplier and assembly shop;
2. the obscission of nut can not take place to install in advance in bumper assembly in transportation process;
3. the relevant plaque in the bumper assembly need not increase linkage structure, simplifies mould, has improved the product integration, good economy performance.
Description of drawings
Fig. 1 is the schematic representation of the U-nut of existing technology.
Fig. 2 connects the fundamental diagram of Abdeckung Stossfaenger and bumper assembly lower cover plate for the U-nut that uses existing technology.
Fig. 3 is the schematic representation of the U-nut structure that is used for bumper of the utility model.
Fig. 4 is a U-nut structure shown in Figure 3 sectional view along the A-A line.
Fig. 5 is a U-nut structure shown in Figure 3 sectional view along the B-B line.
Embodiment
Below, be elaborated in conjunction with the U-nut structure of accompanying drawing to the utility model.
Fig. 3 is the schematic representation of the U-nut structure that is used for bumper of the utility model, and Fig. 4 is a U-nut structure shown in Figure 3 sectional view along the A-A line.Shown in Fig. 3 and 4, the side on the said top of U-nut 1 has the joint 5 that is connected with bumper assembly lower cover plate 4, and said U-nut 1 becomes one with said bumper assembly lower cover plate 4 through said joint 5.
As shown in Figure 3; The top of said U-nut 1 is made up of a pedestal and a protuberance; Said joint 5 is positioned at a side of said pedestal, and said joint 5 is the downward bending shapes of one 90 degree, and the lower end of joint 5 and said bumper assembly lower cover plate 4 are integrated.Preferably, the protuberance of said nut 1 is positioned at the center of said pedestal, and said first perforate is arranged in said protuberance.Be that with the difference of existing technology the bottom of the U-nut 1 of the utility model promptly is a bumper assembly lower cover plate 4.
Fig. 5 is a U-nut structure shown in Figure 3 sectional view along the B-B line.Shown in Figure 4 and 5, the center on the top of U-nut 1 has threaded first perforate.Because U-nut 1 only at an upper portion thereof a side has said joint 5, therefore in Fig. 5, can not find out between U-nut 1 and the bumper assembly lower cover plate 4 to become one.Shown in Figure 4 and 5, bumper assembly lower cover plate 4 has and corresponding second perforate in the position of said first perforate.In addition, Abdeckung Stossfaenger 2 has the 3rd perforate, and said the 3rd perforate is corresponding each other on the position with said first perforate, second perforate.
The assembly process of facing the U-nut structure of the utility model is down carried out brief description.Since U-nut 1 directly on lower cover plate 4 injection moulding come out, so Abdeckung Stossfaenger 2 can directly insert in the U-nut 1.Said first perforate, second perforate and the 3rd perforate are aligned with each other, and screwed self tapping screw 3 passes said first perforate, second perforate and the 3rd perforate from bottom to top successively.In addition, the screw-thread fit in the screw thread of self tapping screw 3 and first perforate, thus in first perforate, lock.Operating process is simple and convenient, does not need extra independent use nut.
Preferably, U-nut 1 and bumper assembly lower cover plate 4 once injection moulding in a mould of the utility model, and U-nut 1 adopts identical materials, for example plastics or metallic material with bumper assembly lower cover plate 4.
The scope of the utility model is not limited in above-described content.Those skilled in the art can carry out various deformation and modification to the foregoing description under the prerequisite that does not break away from the utility model technical conceive, and these distortion and modification all should be worked as in the scope that belongs to the utility model.
