Abstract

The utility model discloses an oil pan of an automobile engine, which comprises a groove-form casing. Surfaces of the inner lateral periphery and the outer lateral periphery of the groove-form casing are respectively connected with a longitudinal concave arc groove (1). By properly reducing the thickness of iron plates for punching and stretching, a casing of which the surfaces of the inner lateral periphery and the outer lateral periphery are connected with the longitudinal concave arc grooves is formed, thereby strengthening the rigidity and the bearing strength thereof, and increasing the connecting smoothness of end faces of the casing and the heat dissipating area of the casing. Compared with the prior art, the oil pan of an automobile engine efficiently guarantees to tightly connect and seal with the lower end face of the engine without leaking engine oil, obviously reduces the using cost of products, and increases auxiliary heat dissipating and temperature reduction effect of an oil radiator of the engine.

Description

Automobile engine oil pan

(1) technical field:

The utility model relates to automotive engine component; Be specifically related to a kind of automobile engine oil pan.

(2) background technique:

Be connected in the oil sump of motor car engine lower end in the prior art, its structure normally adopts iron plate punching stretch formation to have the groove shape housing that the degree of depth does not wait, and described groove shape housing is built-in with machine oil.The flat surface of described housing periphery plays certain for the cooling effect of motor car engine oil radiator auxiliary heat dissipation usually.Exist not enough: because described housing periphery is plane, in the punching stretch forming process, be subjected to the influence of its material stress deformation, housing is very yielding to cause it to connect the end face out-of-flatness, when being connected sealing with the installation of motor lower end surface, often because of engaging the poorly sealed seepage machine oil phenomenon that occurs; As increase iron plate thickness, then obviously increased the user cost of product; The 2nd, the housing periphery is a flat surface, and its heat diffusion area is less, the corresponding auxiliary heat dissipation cooling-down effect that has reduced the engine motor oil radiator.

(3) summary of the invention:

At the deficiency that above-mentioned prior art exists, the purpose of this utility model is, provides that a kind of to engage sealing tight and reduce the automobile engine oil pan that product cost increases the auxiliary heat dissipation cooling-down effect again.

For achieving the above object, the technological scheme of the utility model automobile engine oil pan is achieved in that and comprises groove shape housing; Its improvement is: on the medial and lateral periphery surface of described groove shape housing, be connected with vertical concave circular arc groove respectively.

The utility model has strengthened the rigidity and the bearing strength of iron plate punching stretch formation housing by adopting the structure that is connected with vertical concave circular arc groove on the periphery surface of above-mentioned housing medial and lateral respectively.Improve the housing end face and be connected the planarization that seals with the motor lower end surface.The housing medial and lateral periphery surface that the concave circular arc groove joins and constitutes has increased its radiating and cooling area again.Through testing: wall thickness is the rigidity and the bearing strength of the utility model housing of 1.5mm, is the rigidity and the bearing strength of the prior art housing of 2mm greater than wall thickness.Guaranteed to engage the tight non-leakage machine oil of sealing effectively, reduced the user cost of product significantly and increased the auxiliary heat dissipation cooling-down effect of engine motor oil radiator with the motor lower end surface.

(4) description of drawings:

Fig. 1 is the utility model housing surface of internal cavity three-dimensional view;

Fig. 2 is the utility model hull outside surface three-dimensional view.

(5) embodiment:

Fig. 1-shown in Figure 2.This automobile engine oil pan comprises groove shape housing; It is on the surface, medial and lateral of described groove shape housing, constitutes the uniform concave circular arc groove 1 that joins (Fig. 1, shown in Figure 2) respectively by the press punching stretch forming.Certainly, according to different designing requirements, the utility model can also be set as the concave circular arc groove and be spacing with the plane and be connected the shape (not shown).The utility model can be set as different size dimensions according to the model specification of different automobiles.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characteristics that the process creative work just can be associated; can also make some modification and improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.

Claims (2)

1, a kind of automobile engine oil pan comprises groove shape housing; It is characterized in that: on the medial and lateral periphery surface of described groove shape housing, be connected with vertical concave circular arc groove (1) respectively.

2, automobile engine oil pan according to claim 1, it is characterized in that: vertical concave circular arc groove (1) that described housing medial and lateral periphery surface is connected with respectively is that the concave circular arc groove connects shape or concave circular arc groove and is spacing with the plane and is connected the wherein a kind of of shape.
