Description

Part with gap at bending position

Technical Field

The utility model relates to the field of automobile parts, in particular to a part with a gap at a bent part.

Background

The bending radius of a bending part of a general part is smaller than that of an outer ring when the part is bent, so that wrinkles or burrs are generated after the part is bent, the appearance is not good, the structure is seriously abraded, a notch is formed in the bending part of the bendable part in the existing market to solve the problem that burrs or wrinkles are generated in a bending area after the part is bent, the notch is also abraded frequently after the part is bent, and the bent structure is unstable after a long time; for example, in chinese patent document, "a reinforcing rib for an automobile sunroof glass having a notch at an end portion of a bent portion" is disclosed as "CN 205075626U", and a design in which a notch is provided in a bent region is adopted, and this structure is easily worn after long-term use, and stability of the bent structure cannot be ensured.

Disclosure of Invention

The utility model mainly solves the problem of poor stability of an easily-worn structure of a bending area in the prior art, and provides a part with a gap at a bending part, wherein the technical effect of the utility model is realized by the following technical scheme:

the bending device comprises a fixing part and a bending unit, and is characterized in that the bending unit is provided with at least 2 bending gaps, the bending gaps are tooth-shaped, the lower surface of the fixing part is provided with a fixing part, the top ends of the bending gaps are provided with connecting pieces, and two ends of each connecting piece are respectively connected with the tops of two side walls of the tooth-shaped bending gaps. The bending unit is provided with a plurality of bending gaps, so that bending is softer, and the bending capability of the part is enhanced. The fixing piece arranged on the lower surface can fix the bent part on the assembly shell; the connecting piece is made of bendable elastic materials, and can fill the gap which is generated by the fact that the bending gap cannot be closed after bending, so that the bending surface of the part is smooth, and supporting force is provided for the bending unit.

Preferably, the fixing portion and the bending unit are of an integral structure. The fixing part and the bending unit are designed into a whole instead of being connected through the connecting mechanism, so that the connecting strength between the fixing part and the bending unit can be enhanced, and the fixing part and the bending unit are prevented from being separated during fixing and bending.

Preferably, the bending slits are equal in size. The gap that the size equals makes the laminating that the unit can be better when buckling of buckling, improves the stability of structure.

Preferably, there are two fixing portions, and the fixing portions are respectively disposed at both sides of the bending unit. The fixing parts are arranged on two sides of the bending unit, so that the fixing effect can be enhanced, and the bending part is prevented from rebounding.

Preferably, the number of the fixing parts is at least 4, and the fixing parts are symmetrically arranged on the lower surfaces of the fixing parts at two sides of the bending unit. A plurality of mountings just the symmetry sets up can share owing to the resilience force of buckling the production on two fixed parts, additional strengthening intensity.

Preferably, the fixing member is wedge-shaped. The side of mounting sets up 1 at least recess, the cross section direction of recess with the lower surface of fixed part is parallel. The side face of the fixing piece is provided with the groove, so that the fixing piece and the assembling shell can be conveniently connected in a clamping mode, and the fixing piece is not easy to separate.

The utility model has the beneficial effects that: 1. the bending position is provided with a bending gap to avoid generating folds and burrs during bending.

2. The connecting piece is arranged in the bending gap to enable the bending surface to be smooth, and the structural strength of the bending surface is improved.

3. The fixing part and the bending unit are integrated and are provided with fixing parts, so that the fixing effect is enhanced.

Detailed Description

The technical scheme of the utility model is further specifically described by the following embodiments and the accompanying drawings.

Example (b):

the part with the gap at the bending part comprises a fixing part 1 and a bending unit 2, wherein the fixing part 1 and the bending unit 2 are integrally manufactured on the same bendable material, and the bendable material can be common aluminum materials, stainless steel and the like, as shown in figure 1. Bending unit 2 is provided with bending gap 3, and bending gap 3 is the cusp, and bending gap 3 has 2 at least, and the lower surface of fixed part 1 is provided with mounting 4, and bending gap 3's top is provided with connecting piece 31. The two ends of the connecting piece 31 are respectively connected with the tops of the two side walls of one bending gap 3, after bending, the connecting piece 31 is of an elastic bendable structure due to the fact that the gap is reduced, the connecting piece 31 can be compressed between the gaps to be used as filling of the gap, and the bending force can be made to be more flexible by the elastic material. The elastic material of the connecting member 31 may be a soft and elastic material such as rubber.
