Description

Technical Field

[0001] The invention relates to the technical field of clamps, and in particular to an open-fitting clamping bracket for fuel cell hydrogen energy automobile parts. Background Art

[0002] In the structural design of automobiles or other mechanical fields, an open-fit clamping device is usually used to clamp parts with through holes. The clamping device includes a clamping bracket; the clamping bracket and the clamped part are usually clearance-fitted, and after assembly, the clamped part is locked or fixed by tightening a through bolt inserted into the clamping bracket.

[0003] There are two types of structural designs of clamping brackets in the prior art, one is a sheet metal stamping structure, and the other is a casting structure. For sheet metal stamping structures, since sheet metal is easy to deform, the clamping bracket can generate sufficient clamping force to prevent the clamped parts from slipping when clamped, but the strength of this clamping bracket is limited. In order to achieve sufficient strength, the sheet metal thickness can only be increased or the flange can be turned. However, increasing the sheet metal thickness or the flange will reduce the deformation ability of the clamping bracket, and ultimately reduce the clamping force of the clamping bracket. For casting structures, the casting can increase the wall thickness or strengthen the ribs and other features to make the clamping bracket have higher strength to prevent the clamping bracket from being damaged. However, due to the poor deformation ability of the casting, too thick a wall of the casting or too strong a reinforcement will also reduce the clamping force of the clamping bracket. Summary of the invention

[0004] The invention aims to solve the technical problem that the existing clamping bracket cannot have both high strength and good deformation ability.

[0005] An embodiment of the present invention provides an open-fitting clamping bracket for fuel cell hydrogen energy automobile parts, comprising a first connecting portion and two clamping portions; the two clamping portions are arranged at two ends of the first connecting portion opposite to each other;

[0006] The clamping part is a hollow double-layer structure, and the clamping part includes an inner layer plate, an outer layer plate and a second connecting part; the second connecting part is located between the inner layer plate and the outer layer plate, and the inner layer plate and the outer layer plate are connected through the second connecting part;

[0007] The inner layer plate is provided with mounting holes, and the mounting holes are used for mounting bolts;

[0008] The outer layer plate is provided with avoidance holes, and the avoidance holes are used to facilitate the installation of the bolts.

[0009] In some preferred embodiments, the avoidance hole is coaxially arranged with the mounting hole; and the aperture of the avoidance hole is larger than the aperture of the mounting hole.

[0010] In some preferred embodiments, the two clamping parts are respectively connected to the ends of the first connecting part.

[0011] In some further preferred embodiments, the first connecting portion includes a first sub-connecting member and a second sub-connecting member; the first sub-connecting member and the second sub-connecting member are relatively arranged between the two clamping portions.

[0012] In some further preferred embodiments, the first sub-connector and / or the second sub-connector is located at the lower ends of the two clamping parts.

[0013] In some further preferred embodiments, the first sub-connector or the second sub-connector is a transverse plate.

[0014] In some preferred embodiments, the second connection portion includes a third sub-connector and a fourth sub-connector, and the third sub-connector and the fourth sub-connector are relatively arranged between the inner layer plate and the outer layer plate.

[0015] In some further preferred embodiments, the inner layer plate, the outer layer plate, the third sub-connector and the fourth sub-connector are combined to form a hollow cavity, and the mounting hole and the avoidance hole are respectively connected to the hollow cavity.

[0016] In some further preferred embodiments, the third sub-connector or the fourth sub-connector is a transverse plate.

[0017] The technical solution provided by the embodiment of the present invention has the following beneficial effects: the fuel cell hydrogen energy automobile parts with through holes are installed between the two clamping parts by combining the avoidance holes opened on the outer layer plate and the mounting holes opened on the inner layer plate with bolts, the two clamping parts are relatively located at the two ends of the first connecting part and are respectively connected to the first connecting part, the two clamping parts of the hollow double-layer structure have an inner layer plate, an outer layer plate and a second connecting part, and the clamping part of the hollow double-layer structure enables the clamping bracket to have sufficient strength to ensure that the clamping bracket is not damaged when subjected to a large load; the inner layer plate connected to the outer layer plate through the second connecting part is a single-layer design and has good deformation ability; when the fuel cell hydrogen energy automobile parts are clamped, by tightening the bolts, the inner layer plates of the two clamping parts are driven to deform inward to a certain extent, ensuring that the clamping bracket can generate sufficient clamping force to prevent the clamped parts from slipping during clamping, and at the same time, the clamping part of the double-layer hollow structure enables the clamping bracket to have sufficient strength to ensure that the clamping bracket is not damaged when subjected to a large load, so that the clamping bracket proposed by the present invention has high strength and good deformation ability.
