Description

Technical Field

[0001] This utility model relates to a front cover, specifically a front cover for a car engine water pump. Background Technology

[0002] The engine block and cylinder head are made of different materials and have different coefficients of thermal expansion. When heated, they expand differently, causing a height difference between the sides of the block and cylinder head, which affects the installation of the front cover. Utility Model Content

[0003] To address the shortcomings of the prior art, this utility model provides a front cover plate for a car engine water pump. This utility model features a glue groove in the front cover plate for applying glue. The expanded foam glue fills the gaps caused by the height difference, resulting in low cost and convenient grooving and glue application.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a front cover plate for a car engine water pump, comprising a front cover plate body, wherein a first adhesive groove is provided on a first side of the front cover plate body and a second adhesive groove is provided on a second side, wherein expanding foam is provided in the first adhesive groove and the second adhesive groove.

[0005] The first adhesive groove includes a second wide section, a first middle section, and a third wide section arranged in sequence. The second wide section extends toward the inner side of the front cover body, and the third wide section extends toward both the inner and outer sides of the front cover body. The width L3 of the third wide section is greater than the width L2 of the second wide section, and the width L2 of the second wide section is greater than the width L8 of the first middle section.

[0006] Both the second and third wide sections are arc-shaped.

[0007] The lengths of the first adhesive groove are L1 = 17.7 mm, L2 = 2.9 mm, L3 = 5 mm, and L8 = 1.7 mm.

[0008] The second adhesive groove includes a wide section four, a middle section two, and a wide section five arranged in sequence. The wide section four extends to the inner and outer sides of the front cover body, and the wide section five extends to the inner and outer sides of the front cover body. The width L5 of the wide section four is greater than the width L6 of the wide section five, and the width L6 of the wide section five is greater than the width L8 of the middle section two.

[0009] The lengths of the second adhesive groove are L4 = 17.7 mm, L5 = 5 mm, L6 = 3.1 mm, and L8 = 1.7 mm.

[0010] The first and second glue tanks are arc-shaped grooves with a depth L7 = 0.5 mm.

[0011] In summary, this utility model achieves the following technical effects:

[0012] This invention features a glue groove in the front cover plate. Expanding foam is applied into the groove, and after expansion, it fills the gap between the cylinder block and the cylinder head, ensuring stable installation and preventing dust and other contaminants from entering. There are two glue grooves, one on each side of the front cover plate, which can fill gaps on both sides. Attached Figure Description

[0024] Example:

[0025] Figure 1 It is a front cover plate for a car engine water pump, including a front cover plate body. A first adhesive groove 1 is provided on a first side of the front cover plate body and a second adhesive groove 2 is provided on a second side. Foaming adhesive is provided in the first adhesive groove 1 and the second adhesive groove 2.

[0026] This invention features a glue groove in the front cover plate. Expanding foam is applied into the groove, and after expansion, it fills the gap between the cylinder block and the cylinder head, ensuring stable installation and preventing dust and other contaminants from entering. There are two glue grooves, one on each side of the front cover plate, which can fill gaps on both sides.

[0027] Figure 2 yes Figure 1The enlarged schematic diagram of part A shows that the first adhesive groove 1 includes a second wide section 12, a first middle section 11, and a third wide section 13 arranged sequentially. The second wide section 12 extends inward to the inner side of the front cover body, and the third wide section 13 extends inward and outward to the front cover body. The width L3 of the third wide section 13 is greater than the width L2 of the second wide section 12, and the width L2 of the second wide section 12 is greater than the width L8 of the first middle section 11 (L8 is in...). Figure 5 (As shown).

[0028] This invention sets the two ends of the first glue groove to be wider than the middle section, allowing more expanding foam to extend to both ends for better filling effect. To accommodate the structure of the front cover, the second wide section 12 extends inward and the third wide section extends to both sides, which can make full use of the plane of the front cover and prevent interference with the installation of other parts.

[0029] Both the second wide section 12 and the third wide section 13 are arc-shaped.

[0030] The lengths of the first adhesive groove 1 are L1 = 17.7 mm, L2 = 2.9 mm, L3 = 5 mm, and L8 = 1.7 mm.

[0031] Figure 3 yes Figure 1 The enlarged schematic diagram of part B shows that the second adhesive groove 2 includes a wide section 4 22, a middle section 21, and a wide section 5 23 connected in sequence. Wide section 4 22 extends towards the inner and outer sides of the front cover body, and wide section 5 23 extends towards the inner and outer sides of the front cover body. The width L5 of wide section 4 22 is greater than the width L6 of wide section 5 23, and the width L6 of wide section 5 23 is greater than the width L8 of middle section 21 (L8 is in...). Figure 5 (As shown).

[0032] This invention sets the two ends of the second glue groove to be wider than the middle section, which allows more expanding foam to be applied and extend to both ends, resulting in a better filling effect.

[0033] The second groove is inclined, with wide sections 22 and 23 located in the two through-hole areas to accommodate the inclined section of the front cover.

[0034] The lengths of the second adhesive groove 2 are L4 = 17.7 mm, L5 = 5 mm, L6 = 3.1 mm, and L8 = 1.7 mm.

[0035] Figure 4 yes Figure 2The cross-sectional diagram along the N-N direction is shown. Since N-N and M-M are both cross-sectional diagrams of the middle sections of the two glue tanks, the middle sections of the first glue tank and the second glue tank have the same structure. That is, the middle section 11 and the middle section 21 are the same. Therefore, the cross-sections of the two glue tanks are the same, and the cross-section of M-M is omitted. Figure 5 yes Figure 4 Enlarged schematic diagram of part O in the middle. The first glue groove 1 and the second glue groove 2 are arc-shaped grooves with groove depths L7 = 0.5 mm and L8 = 1.7 mm.

[0036] The depth of the entire first and second glue tanks is L7, and the width of the middle section 11 and the middle section 21 is L8.

[0037] The drop can also cause oil leakage. Although the probability of oil leakage is one in a thousand, there is still a risk. This utility model fills the gap with foam to form a seal between the front cover plate and the cylinder head to prevent oil leakage.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
