Description

Technical Field

[0001] The utility model relates to an intake manifold. Background Art

[0002] The intake manifold is an important component in an internal combustion engine. It is located behind the throttle body and in front of the engine's intake port. Its main function is to evenly distribute air (or in a gasoline engine, a mixture of air and fuel) to each cylinder. The intake manifold is usually made of cast iron, aluminum alloy or other lightweight materials and has multiple branch channels corresponding to each cylinder of the engine.

[0003] In the process of pursuing high engine speeds, most existing intake manifolds are straight pipes. Since they can provide a more direct and smoother air flow path, they can reduce the resistance of air flow.

[0004] However, in some compact engine compartments, a straight intake manifold may require more straight space for layout, and at this time, it may be difficult for the straight intake manifold to fit the compact installation space. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an intake manifold that can change the direction of the air flow by setting the shapes of the first pipe body and the second pipe body to be curved and can fit the compact installation space when there is not enough straight space.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: It includes an intake manifold body, the intake manifold body includes a first installation part at the top, a second installation part at the bottom, and a first pipe body and a second pipe body located between the first installation part and the second installation part. The interiors of the first pipe body and the second pipe body are both hollow. The first pipe body is arc-shaped from top to bottom and from right to left, and the second pipe body is arc-shaped from top to bottom and from left to right.

[0007] The utility model is further provided with: It also includes a cleaning pipe located inside the first pipe body. The cleaning pipe is hollow and its outer periphery abuts against the inner wall of the first pipe body. The top and bottom of the cleaning pipe are respectively detachably connected to the first installation part and the second installation part. The cleaning pipe is made of a high-temperature resistant flexible material.

[0008] The utility model is further provided with: A plurality of reinforcing ribs are arranged at intervals along the circumferential direction on the inner wall of the cleaning pipe, and the inner walls of the reinforcing ribs are all fixedly connected to the cleaning pipe.

[0009] The utility model is further provided with: The cross-section of each of the reinforcing ribs is arc-shaped with the opening facing the inner wall of the cleaning pipe.

[0010] The present utility model is further configured such that: a plurality of positioning insertion blocks are circumferentially arranged at the top of the cleaning pipe, and positioning slots are correspondingly arranged in the first mounting portion for each positioning insertion block.

[0011] The present utility model is further configured such that: a first magnet is arranged on each of the positioning insertion blocks, and a second magnet is arranged in each positioning slot in the first mounting portion.

[0012] The present utility model is further configured such that: the cleaning pipe includes a plurality of limiting insertion blocks spaced circumferentially along the bottom. Each limiting insertion block includes a fixed section connected to the cleaning pipe and a limiting section located below the fixed section. The upper end surface of each limiting section abuts against the lower end surface of the second mounting portion.

[0013] By adopting the above technical solutions, 1. Since both the first pipe body and the second pipe body are arc-shaped, when the straight-line space is insufficient, the arc-shaped intake manifold body can be installed to facilitate assembly; 2. The arc-shaped first pipe body and second pipe body can change the gas flow path, so that the intake path can be far away from the hotter part of the engine, thereby helping to maintain a lower intake temperature.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0029] As Figures 1-7 shown, the present invention discloses an intake manifold, including an intake manifold body 1. The intake manifold body 1 includes a first mounting part 2 at the top, a second mounting part 3 at the bottom, and a first pipe body 4 and a second pipe body 5 located between the first mounting part 2 and the second mounting part 3. Among them, flange plates are usually provided on the first mounting part 2 and the second mounting part 3 of the intake manifold body 1 and are respectively connected to the throttle valve and the engine intake port (i.e., the engine cylinder head), so as to realize that air or a mixture of air and fuel can be evenly distributed into each cylinder (this is the prior art, not specifically described here and the throttle valve and the engine cylinder head are not shown in the figure). The interiors of the first pipe body 4 and the second pipe body 5 are both hollow. The first pipe body 4 is arranged in an arc shape from top to bottom and from right to left, and the second pipe body 5 is arranged in an arc shape from top to bottom and from left to right. 1. Since both the first pipe body 4 and the second pipe body 5 are arranged in an arc shape, when the straight-line space is insufficient, by installing the intake manifold body 1 with an arc shape, it is convenient for assembly; 2. The arc-shaped first pipe body 4 and second pipe body 5 can change the gas flow path, so that the intake path can be far away from the hotter part of the engine, thereby helping to maintain a lower intake temperature.

[0030] Among them, it also includes a cleaning tube 6 located in the first tube body 4, the cleaning tube 6 is hollow and the outer periphery is against the inner wall of the first tube body 4, the top and bottom of the cleaning tube 6 are detachably connected to the first mounting part 2 and the second mounting part 3 respectively, and the cleaning tube 6 is made of high-temperature resistant flexible materials such as silicone rubber and fluororubber. 1. Since the top and bottom of the cleaning tube 6 are detachably connected to the first mounting part 2 and the second mounting part 3 respectively, carbon deposits can be accumulated on the inner wall of the cleaning tube 6 during the movement of gas, and when it needs to be cleaned, the flexible cleaning tube 6 can be taken out of the first tube body 4 by separating it from the first mounting part 2 and the second mounting part 3, and the inner wall can be cleaned directly by bending it, thereby avoiding the need to bend the brush and extend it into the curved first tube body 4, thereby improving the cleaning efficiency; 2. Since the cleaning cover is resistant to high temperature, the cleaning cover is not easily deformed during the operation of the engine, thereby extending its service life.

[0031] Among them, the inner wall of the cleaning tube 6 is provided with a number of reinforcing ribs 61 at intervals along the circumferential direction, and the inner wall of each reinforcing rib 61 is fixedly connected to the cleaning tube 6. The arrangement of each reinforcing rib 61 can effectively improve the structural strength of the cleaning tube 6, thereby reducing the possibility of deformation of the cleaning tube 6 when under pressure.

[0032] Preferably, the cross-section of each of the reinforcing ribs 61 is an arc-shaped arrangement with its opening toward the inner wall of the cleaning tube 6. 1. Since the cross-section of each of the reinforcing ribs 61 is an arc-shaped arrangement with its opening toward the inner wall, the cross-section of each of the reinforcing ribs 61 is a parabolic arrangement with its opening outward. When carbon deposits fall onto each of the reinforcing ribs 61, due to the action of their own gravity, they can fall toward the lower heights on both sides during the operation of the engine and then move along the shapes of both sides and toward the inner wall of the cleaning tube 6; 2. Since the area of the outer side of each of the reinforcing ribs 61, that is, the part in contact with the cleaning tube 6, is the largest, each of the reinforcing ribs 61 can be stably fixed to the inner wall of the cleaning tube 6.

[0033] Among them, a plurality of positioning blocks 62 are circumferentially arranged on the top of the cleaning tube 6, and a positioning slot 21 is provided corresponding to each positioning block 62 of the first mounting part 2. After the cleaning tube 6 is installed in the first tube body 4, each positioning block 62 on the top of the cleaning tube 6 will enter the corresponding positioning slot 21 respectively, making it impossible for the cleaning tube 6 to rotate and move longitudinally compared with the first tube body 4, thereby completing the relative position determination of the cleaning tube 6 and the first tube body 4. When the cleaning tube 6 needs to be separated from the first tube body 4, after the separation of the bottom of the cleaning tube 6 and the second mounting part 3 is released, the top is bent so that each positioning block 62 can move upward and then be separated from the corresponding positioning slot 21. At this time, the cleaning tube 6 can be taken out from the first tube body 4.

[0034] Preferably, each positioning block 62 is provided with a first magnet 621, and the first mounting portion 2 is provided with a second magnet 22 in each positioning slot 21. When each positioning block 62 falls into the corresponding positioning slot 21, the first magnet 621 of each positioning block 62 will be attracted to the corresponding second magnet 22, thereby further improving the connection strength between the top of the cleaning tube 6 and the first mounting portion 2.

[0035] Wherein, the cleaning tube 6 includes a plurality of limiting plugs 63 spaced circumferentially at the bottom, each limiting plug 63 includes a fixed section 631 connected to the cleaning tube 6 and a limiting section 632 located below the fixed section 631, and the upper end surface of each limiting section 632 is against the lower end surface of the second mounting portion 3. In the process of installing the cleaning tube 6 into the first tube body 4, the bottom of the cleaning tube 6 is the first to enter the first mounting portion 2. Therefore, at this time, the limiting plug 63 at the bottom of the cleaning tube 6 will be squeezed by force and then enter the inner wall of the first tube body 4. When each limiting plug 63 passes over the bottom of the first tube body 4 and enters the second mounting portion 3, the limiting section 632 can contact the second mounting portion 3. The lower end surface of the mounting portion 3 is abutted against each other, and at the same time, each positioning plug 62 is located in the corresponding positioning slot 21, and the stable connection between the cleaning tube 6 and the first tube body 4 is completed. When the cleaning tube 6 needs to be removed from the first tube body 4, the limiting plugs 63 are bent inward so that they can enter the inner wall of the first tube body 4 and move upward. As the limiting plugs 63 move upward, each positioning plug 62 will move upward and separate from the corresponding positioning slot 21. When it is forcibly crossed over the first mounting portion 2 and separated from it, the separation of the cleaning tube 6 and the first tube body 4 is completed, and the cleaning tube 6 can be cleaned, so that the carbon deposits on the inner wall of the cleaning tube 6 are cleaned.

[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
