To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Embodiments of the present application are set forth in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
It will be understood that spatial relationship terms, such as "under", "below", "beneath", "below", "over", "above", and the like, may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements or features described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary terms "under" and "under" can encompass both an orientation of above and below. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations) and the spatial descriptors used herein interpreted accordingly.
Example one
An anti-deformation reinforcing method for an oil tank comprises the following steps.
(a) Deformation of the lower shell 1 of the oil tank is analyzed through CAE, and the position with the maximum deformation is found out.
(b) A lower mounting hole 11 with the diameter of 18mm is drilled at the maximum deformation position of the lower shell 1, and an upper mounting hole 21 with the diameter of 18mm is drilled at the corresponding position of the upper shell 2.
(c) Welding a hollow reinforcing column 3 with the outer diameter of 18mm and the wall thickness of 2mm between the upper shell 2 and the lower shell 1; one end of the reinforcing column 3 is welded to the upper case 2 and communicates with the upper mounting hole 21, and the other end is welded to the lower case 1 and communicates with the lower mounting hole 11.
In this embodiment, although the lower shell 1 and the upper shell 2 of the fuel tank have been designed by optimizing the structure of the lower shell and adding reinforcing ribs to reduce the deformation, the CAE analysis result in step (a) shows that the deformation of the lower shell 1 is still large, and the maximum deformation is about 10mm, which is far more than the allowable deformation.
In the embodiment, the mounting hole 11 is drilled at the position with the maximum deformation of the lower shell 1, the mounting hole 21 is drilled at the corresponding position of the upper shell 2, and the upper shell and the lower shell are restrained by welding the reinforcing column 3 at the lower mounting hole 11 and the upper mounting hole 21, so that the deformation is fundamentally prevented. Through CAE analysis, the deformation after strengthening is about 5mm, accords with the design requirement.
Example two
An oil tank deformation-preventing reinforcing structure comprises a lower shell 1, an upper shell 2 and a reinforcing column 3. The lower housing 1 and the upper housing 2 are fitted. The top edge of the lower shell 1 is provided with a lower flanging 13, the bottom edge of the upper shell 2 is provided with an upper flanging 23, and the lower flanging 13 and the upper flanging 23 are connected through threads, so that the lower shell 1 and the upper shell 2 form a complete oil tank.
The maximum deformation of the lower shell 1 is provided with a lower mounting hole 11, the edge of the lower mounting hole 11 is turned upside down to form a lower flanging 12, and the diameter of the lower mounting hole 11 is 18 mm.
An upper mounting hole 21 is provided at a corresponding position of the upper housing 2, and the upper mounting hole 21 is located right above the lower mounting hole 11. The edge of the upper mounting hole 21 is turned downwards to form an upper flanging 22, and the diameter of the upper mounting hole 21 is also 18 mm.
The reinforcing column 3 can be made of hollow steel pipes, the outer diameter is 18mm, the outer diameter of the reinforcing column is matched with the lower mounting hole 11 and the upper mounting hole 21, and the wall thickness of the reinforcing column is 2 mm. The reinforcing column 3 is installed between the lower casing 1 and the upper casing 2.
The bottom end of the reinforcing column 3 is communicated with the lower mounting hole 11, and the lower flanging 12 is tightly attached to the outer wall of the reinforcing column 3 to cover the bottom of the reinforcing column 3. The reinforcement column 3 is fixed to the turned-down edge 12 by welding, thereby fixing the bottom end of the reinforcement column 3 to the lower case 1.
The top end of the reinforcing column 3 is communicated with the upper mounting hole 21, and the upper flange 22 is tightly attached to the outer wall of the reinforcing column 3 to cover the top of the reinforcing column 3. The reinforcement column 3 is fixed to the upper flange 22 by welding, thereby fixing the tip of the reinforcement column 3 to the upper case 2.
According to the invention, the reinforcing column 3 is additionally arranged between the lower shell and the upper shell, so that the deformation problem is solved, the mode of the oil tank is improved, and the NVH (noise, vibration and harshness) noise vibration transmission of the oil pump is reduced; the weight of only one reinforcing column 3 is increased, the weight is light, a new oil tank die does not need to be added, only punching and welding processes need to be added, and the price is low.
In addition, water may accumulate in the lower recess of the upper shell of the oil tank, which may cause corrosion of the oil tank for a long time. The reinforcing column 3 is of a hollow structure and is communicated up and down, water can flow out from top to bottom, and the oil tank is prevented from being corroded due to water accumulated in a shell on the oil tank.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
