Description

Technical Field

[0001] This utility model relates to the field of intake manifold installation technology, and in particular to an intake manifold bracket structure for an automobile engine. Background Technology

[0002] The intake manifold is an important component of the engine. It is usually mounted on the outer wall of the cylinder block and then fixed in place by a manifold bracket.

[0003] However, when installing manifold supports now, after drilling, one hand is usually needed to hold the support to keep it in place while the other hand tightens the fasteners (such as screws and bolts), which makes the installation operation extremely inconvenient and inefficient. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an intake manifold support structure for an automobile engine.

[0005] To achieve the above objectives, the specific solution of this utility model is as follows:

[0006] An intake manifold bracket structure for an automobile engine includes a bracket body and a mounting boss disposed on the outer wall of the cylinder block; the mounting boss has at least one first mounting hole; and one end of the bracket body has at least one second mounting hole correspondingly passing through it.

[0007] The mounting boss is provided with a horizontal limiting groove; the bracket body is provided with at least one limiting arm; the at least one limiting arm is embedded in the limiting groove during installation and cooperates with the limiting groove to keep the bracket body on the outer wall of the cylinder without tipping over.

[0008] Furthermore, the present invention provides two first mounting holes; two second mounting holes; the distance between the two second mounting holes is equal to the distance between the two first mounting holes; and the limiting groove is located between the two first mounting holes.

[0009] Furthermore, in this invention, the limiting groove is located at the midpoint of the line connecting the centers of the two first mounting holes.

[0010] Furthermore, the present invention provides guide slopes on both sides of the opening of the limiting groove.

[0011] Furthermore, the present invention provides two limiting arms; the two limiting arms are spaced apart.

[0012] Furthermore, in this invention, the two limiting arms are torn and formed in the same direction on the bracket body.

[0013] Furthermore, in this invention, the two limiting arms are distributed at both ends of the tear.

[0014] Furthermore, the present invention provides a rounded transition at the free end of the limiting arm.

[0015] Furthermore, both ends of the limiting groove are provided with inclined platforms; the lower end of the inclined platform is smoothly connected to the bottom surface of the limiting groove; the inclined platform is inclined from the end of the limiting groove to the center of the limiting groove along the length direction of the limiting groove.

[0016] The beneficial effects of this utility model are as follows: In actual use, by inserting the limiting arm of the bracket body into the limiting groove of the mounting boss, the bracket body is restricted by the cooperation of the limiting groove and the limiting arm. This allows the bracket body to overcome the tipping problem caused by the offset of its center of gravity from the mounting boss, and keeps the bracket body on the mounting boss without tipping over. Therefore, there is no need to hold the bracket by hand. The hole alignment operation can be performed simply by moving the bracket body horizontally. After the hole alignment, the first mounting hole and the second mounting hole are fastened together with fasteners, and the bracket body can be fixedly installed on the outer wall of the cylinder. The operation is more convenient and the installation efficiency is improved. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.

[0025] Example 1: As Figures 1 to 5 As shown in the figure, the intake manifold bracket structure of an automobile engine described in this embodiment includes a bracket body 2 and a mounting boss 11 disposed on the outer wall of the cylinder block 1; the mounting boss 11 has at least one first mounting hole 12; one end of the bracket body 2 is correspondingly provided with at least one second mounting hole 21; the mounting boss 11 is provided with a limiting groove 13 horizontally; the bracket body 2 is provided with at least one limiting arm 22; the at least one limiting arm 22 is embedded in the limiting groove 13 during installation and cooperates with the limiting groove 13 to keep the bracket body 2 on the outer wall of the cylinder block 1 without tilting.

[0026] Specifically, in actual use, the intake manifold bracket structure of the automobile engine in this embodiment uses the limiting arm 22 of the bracket body 2 to be inserted into the limiting groove 13 of the mounting boss 11. The limiting groove 13 and the limiting arm 22 work together to restrict the bracket body 2, preventing it from tipping over due to the offset of its center of gravity from the mounting boss 11. This allows the bracket body 2 to remain on the mounting boss 11 without tipping, eliminating the need to hold the bracket by hand. The mounting body 2 can be moved laterally for hole alignment. After alignment, the first mounting hole 12 and the second mounting hole 21 are fastened together with fasteners, thus completing the fixed installation of the bracket body 2 on the outer wall of the cylinder block 1. This makes the operation more convenient and improves installation efficiency. Fasteners include, but are not limited to, screws and bolts.

[0027] like Figures 1 to 5 As shown, in some embodiments of the intake manifold bracket structure for an automotive engine, there are two first mounting holes 12 and two second mounting holes 21. The distance between the two second mounting holes 21 is equal to the distance between the two first mounting holes 12. The limiting groove 13 is located between the two first mounting holes 12. Specifically, the two second mounting holes 21 correspond one-to-one with the two first mounting holes 12, so that the bracket body 2 is firmly mounted on the side wall of the cylinder block 1. The limiting groove 13 is located between the two first mounting holes 12 to cooperate with the limiting arm 22, so that the bracket body 2 is stably held on the mounting platform without tipping over, facilitating subsequent tightening of fasteners.

[0028] like Figure 2 and Figure 3As shown, in some embodiments of the intake manifold bracket structure for an automotive engine, the limiting groove 13 is located at the midpoint of the line connecting the centers of the two first mounting holes 12. This embodiment, through the above-described arrangement, further ensures that the bracket body 2 is more stably held on the mounting platform without tipping over, and also facilitates the alignment of the first mounting hole 12 with the second mounting hole 21.

[0029] like Figures 2 to 4 As shown, in some embodiments of the intake manifold bracket structure for an automotive engine, guide ramps 14 are provided on both sides of the opening of the limiting groove 13. Through this configuration, when installing the bracket body 2, the guide ramps 14 cooperate with the limiting arm 22 to guide the bracket body 2, making it easier for the limiting arm 22 to be inserted into the limiting groove 13. Even when the bracket body 2 is placed at an angle, the cooperation between the guide ramps 14 and the limiting arm 22 allows the bracket body 2 to be aligned, facilitating hole alignment.

[0030] like Figure 5 As shown, in some embodiments of the intake manifold bracket structure of the automobile engine, two limiting arms 22 are provided; the two limiting arms 22 are spaced apart. Through this arrangement, the two limiting arms 22 are inserted into the limiting grooves 13, making the bracket body 2 more reliably held on the outer wall of the cylinder block 1 without tipping over due to a shift in the center of gravity, thus improving structural reliability.

[0031] like Figure 5 As shown, in some embodiments of the intake manifold bracket structure for an automotive engine, the two limiting arms 22 are torn in the same direction on the bracket body 2. In some embodiments of the intake manifold bracket structure for an automotive engine, the two limiting arms 22 are distributed at both ends of the tear opening 23. This embodiment, through the above-described arrangement, improves the connection strength between the limiting arms 22 and the bracket body 2, and the structure is easier to manufacture, also saving materials.

[0032] In this embodiment of the automobile engine intake manifold bracket structure, a rounded transition is provided at the free end of the limiting arm 22. Through this feature, the insertion resistance is reduced and scratches to the inner wall of the limiting groove 13 are avoided when the limiting arm 22 is inserted into the limiting groove 13.

[0033] Example 2: Figures 1 to 6 As shown, the difference between this embodiment and Embodiment 1 is that both ends of the limiting groove 13 are provided with inclined platforms 15; the lower end of the inclined platform 15 is smoothly connected to the bottom surface of the limiting groove 13; the inclined platform 15 is inclined from the end of the limiting groove 13 towards the center of the limiting groove 13 along the length direction of the limiting groove 13. The rest of the structure is the same as in Embodiment 1, and will not be described again here.

[0034] Specifically, when the limiting arm 22 is inserted into the limiting groove 13, if the bracket body 2 deviates to the left or right, the limiting arm 22 contacts the inclined surface of the inclined platform 15. As the limiting arm 22 is inserted, the inclined platform 15 guides the bracket body 2 to center, thereby achieving automatic alignment of the first mounting hole 12 and the second mounting hole 21. In this embodiment, through the synergistic effect of the inclined platform 15 and the guide inclined surface 14, the guide inclined surface 14 assists in the insertion of the limiting arm, and the inclined platform 15 achieves automatic alignment, thus making the installation of the bracket body 2 more convenient.

[0035] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
