What has been described herein is merely a preferred embodiment in accordance with the present invention, and those skilled in the art will appreciate on the basis of the preferred embodiment that other ways of implementing the present invention will likewise fall within the scope of the present invention.

In the following detailed description, directional terms, such as "left", "right", "upper", "lower", "front", "rear", "horizontal", and the like, are used with reference to the orientation as illustrated in the drawings. The components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.

As shown in fig. 3 to 4, the welding movable nut assembly according to the present application includes a nut 4 and a fixing plate 3, wherein the fixing plate has a through-hole, one surface of which is attached to a vehicle body by welding or bolting, and the other surface of the fixing plate 3 opposite to the above surface is seated with the nut 4. The nut 4 is provided with an internal thread, preferably in the form of a through hole. Two opposite side edges of the fixing plate 3 are turned upwards and then bent in opposite directions, thereby forming a limiting groove, and the parts bent in opposite directions cover and press corresponding parts of the nut. The nut 4 can move in the horizontal direction along the stopper groove. In use, the bolt is passed through the through hole in the fixing plate, and then the position of the nut mounted on the fixing plate fixed to the vehicle body is finely adjusted so that the bolt is screwed into the nut 4 and then tightened, thereby reliably fixing the relevant component to the vehicle body.

As shown in fig. 4, in the welding movable nut assembly according to the present application, after the relevant parts are fixed to the vehicle body, the fixing plate 3 is in contact with the vehicle body, and thus the contact area thereof is greatly increased as compared with the prior art shown in fig. 2, so that the operation of fixing the relevant parts does not cause a large stress to be generated at the vehicle body, and thus, a deformation situation does not occur.

As shown in fig. 3, both opposite sides of the fixed plate 3 have a reverse-l-shaped cross-sectional configuration, and respective upturned portions of the opposite sides are parallel to each other. As shown in fig. 3-4, in this preferred embodiment, the nut 4 is provided with upwardly projecting claws 5 on both sides in the longitudinal direction of the stopper groove. The jaws 5 define together with the upturned portion of the holding plate the outer edge of the nut 4. The clamping jaw 5 can be integrally formed with the fixing plate or can be a spring sheet welded on the fixing plate 3. In the process of preparing the welding movable nut component, the nut 4 can be firstly placed at the position corresponding to the through hole of the fixing plate 3, then the nut 4 is fixed, then the fixing plate 3 is bent to form a limiting groove, namely, the nut 4 is placed firstly, and then the fixing plate 3 is bent and formed. Preferably, it is possible to manufacture the fixing plate 3 having the upwardly bent portion and the portion bent in the opposite direction in advance, and then slide the nut 4 along the stopper groove into a position approximately corresponding to the through hole of the fixing plate 3, and then prepare the jaws 5. For the structure that the claw 5 and the fixed plate 3 are integrally formed, the following modes can be adopted: cutting two on the fixing plate 3

A shaped notch, when the nut 4 is arranged at the corresponding position of the through hole of the fixing plate 3

Fixing at the shape cutThe fixed plate 3 is bent upwards to form the claw 5.

Although in the embodiment shown in fig. 3-4 the respective upturned portions of the two opposite sides thereof are parallel to each other and the nut 4 is provided with raised claws 5 on both the left and right sides, other forms of fixing plate 3 may be used to define the nut 4 in the present application.

For example, although not shown in the drawings, it will be appreciated by those skilled in the art that the respective upturned portions of the two opposite sides of the fastening plate may be configured to intersect each other with the jaws 5 being provided on the other side of the nut 4. The upturned portions of the two opposite sides thus form a triangular relationship with the jaws 5 on the other side of the nut 4, thereby limiting the horizontal range of movement of the nut 4 to the inside of the triangle.

The shape of the nut 4 may take any configuration. For example, the nut 4 may be provided in a cylindrical or straight polygonal column configuration, and in this case, the two upturned portions of the fixing plate 4 may also be provided to have an arc-shaped configuration corresponding to the outer edge of the cylindrical or straight polygonal column, whereby the horizontal movement range of the nut 4 can be restricted without providing the jaws 5.

Referring further to fig. 3-4, as a preferred embodiment, the nut 4 of fig. 3-4 includes a body portion 41 and a flange 42 retained by a retaining groove and located at a lower end of the body portion 41. The maximum outer edge dimension of the main body portion 41 is smaller than the distance between the portions bent in the directions opposite to each other. The advantage that this configuration brings is that the height of the two upturned portions can be reduced, thereby enabling the overall footprint of the weld nut assembly to be reduced, thereby providing additional space.

Preferably, either one or both of the body portion 41 and the flange 42 may be provided as a cylindrical structure. In this case, the movable distance of the nut 4 in each direction in the horizontal direction is the same, facilitating centering of the nut 4 with the bolt during installation.

As a preferred embodiment, the maximum moving distance of the nut 4 in the horizontal direction may be set to 2 to 10 mm. In this case, when the fixing plate 3 is fixed to the vehicle body, the horizontal movement range of the nut 4 is small, and the nut 4 is easily aligned with the bolt. In the case where the nut 4 is provided with a cylindrical body, the maximum moving range thereof is formed as a circular horizontal moving range having a diameter of 2 to 10 mm.

As a preferred embodiment, the thickness of the fixing plate 3 of the present application may be set to 1-3 mm.

The utility model discloses a welding movable nut subassembly includes nut 4 and fixed plate 3, wherein, fixed plate 3 and automobile body lug connection, and nut 4 borrows by the fixed plate and is fixed in the automobile body. Because the contact area of the fixed plate 3 and the automobile body is large, the use of the welding movable nut component can not lead to the stress concentration condition of the automobile body, and the problem that the structural strength of the automobile body at the position of the welding movable nut component is low is solved.

The scope of protection of the present invention is limited only by the claims. Persons of ordinary skill in the art, having benefit of the teachings of the present invention, will readily appreciate that alternative structures to those disclosed as possible may be substituted for the alternative embodiments disclosed, and that the disclosed embodiments may be combined to create new embodiments, which likewise fall within the scope of the appended claims.
