Description

Technical Field

[0001] This utility model relates to the field of intake manifold technology, and in particular to an improved intake manifold with a boosting function. Background Technology

[0002] The intake manifold is a core component of the engine's intake system. Its function is to evenly distribute air or an air-fuel mixture to each cylinder, ensuring efficient and stable engine operation. Existing improved intake manifolds adjust their length according to different engine operating conditions to ensure turbocharging functionality. At low speeds, a longer intake manifold is used, utilizing the inertia of the intake air to allow more air into the cylinders, increasing torque. At high speeds, it switches to a shorter intake manifold to reduce intake resistance, increase intake volume, and boost power.

[0003] The existing intake manifold is installed on the engine cylinder with bolts and nuts. However, the vibration force generated by the engine cylinder during operation can be easily transmitted to the bolts and nuts, which can easily cause the bolts and nuts to loosen. This can also cause the connection between the intake manifold and the engine cylinder to loosen, thereby affecting the boost effect of the intake manifold. Utility Model Content

[0004] Therefore, it is necessary to provide an improved intake manifold with a boosting function to address the problem that the vibration force generated by the engine cylinder during operation can easily be transmitted to the bolts and nuts, which can easily lead to the loosening of the bolts and nuts and the loosening of the connection between the intake manifold and the engine cylinder.

[0005] The device includes: a manifold body with several bolts on its surface, each bolt having a nut threaded onto its surface; an anti-loosening mechanism including a screw threaded onto the inner wall of the nut, the surface of the screw engaging with the inner wall of the bolt, an air groove on the inner wall of the bolt, a rubber rod slidably connected to the inner wall of the air groove, the surface of the rubber rod engaging with the inner wall of the screw, the surface of the rubber rod slidably connected to the inner wall of the bolt, and a one-way conduit fixedly connected to the inner wall of the bolt, the bottom end of the one-way conduit communicating with the air groove.

[0006] In one embodiment, an exhaust pipe is fixedly connected to the inner wall of the bolt, and the bottom end of the exhaust pipe is connected to the air groove.

[0007] In one embodiment, both the one-way conduit and the exhaust pipe are threaded with rubber plugs.

[0008] In one embodiment, a first magnetic ring is fixedly connected to the bottom end of the rubber stopper, and a second magnetic ring is fixedly connected to the surface of both the one-way conduit and the exhaust pipe. The first magnetic ring and the second magnetic ring are attracted to each other by opposite poles.

[0009] In one embodiment, a rubber spring is fixedly connected to the end of the rubber rod, and the top end of the rubber spring is fixedly connected to the inner top wall of the air groove.

[0010] In one embodiment, two damping rings are fixedly connected to the inner wall of the manifold body.

[0011] In one embodiment, two anti-deviation blocks are fixedly connected to the surface of the bolt, and the surfaces of the anti-deviation blocks are slidably connected to the inner wall of the damping ring. The interaction between the damping blocks and the anti-deviation blocks limits the placement range of the bolt, thereby ensuring that the screw is precisely locked within the bolt.

[0012] In one embodiment, a nylon rope is fixedly connected to the top end of the rubber stopper, and the other end of the nylon rope is fixedly connected to the top end of a bolt. The nylon rope is used to limit the placement range of the rubber stopper, avoiding the risk of loss.

[0013] Beneficial effects 1. The screw is used to initially lock the bolt and nut. By injecting gas into the one-way guide, the gas in the gas groove is sufficient, which pushes the rubber rod down and locks it in the screw, thereby locking the screw. This ensures that the screw firmly locks the bolt and nut, thus ensuring a tight connection between the manifold body and the engine cylinder, preventing loosening at the connection between the manifold body and the engine cylinder, and thus ensuring the boosting effect of the intake manifold. 2. By cooperating with the first magnetic ring, the second magnetic ring, and the rubber plug, a tight connection is achieved between the opening of the one-way guide tube and the exhaust pipe, thereby preventing the gas in the air groove from being discharged through the exhaust pipe, ensuring that there is enough gas stored in the air groove, and thus ensuring that the rubber rod is stably locked in the screw, ensuring a secure lock on the screw, thereby ensuring a tight connection between the manifold body and the engine cylinder, and ensuring the boosting effect of the intake manifold.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes an improved intake manifold with a boosting function.

[0019] In one embodiment, an improved intake manifold with a boosting function includes: a manifold body 100, the surface of which is provided with a plurality of bolts 200, and the surface of the bolts 200 is threadedly connected to nuts 300; an anti-loosening mechanism 400, the anti-loosening mechanism 400 including a screw 401 threadedly connected to the inner wall of the nut 300, the surface of the screw 401 being engaged with the inner wall of the bolt 200, the inner wall of the bolt 200 having an air groove 402, the inner wall of the air groove 402 being slidably connected to a rubber rod 403, the surface of the rubber rod 403 being engaged with the inner wall of the screw 401, the surface of the rubber rod 403 being slidably connected to the inner wall of the bolt 200, and a one-way conduit 404 fixedly connected to the inner wall of the bolt 200, the bottom end of the one-way conduit 404 being connected to the air groove 402.

[0020] It should be noted that the manifold body 100 is a variable intake manifold, which optimizes combustion efficiency under different operating conditions by adjusting the length or cross-sectional area of ​​the intake pipe. The variable intake manifold connects the intake valve and the resonant chamber, and each cylinder is equipped with an independent manifold. It is designed based on fluid dynamics principles and comes in two technical paths: variable length and variable cross-section. The variable intake manifold model can be BMW's DISA.

[0021] The manifold body 100 utilizes the inertia and wave effects of intake air, typically employing a switchable pipe structure with valves controlling the length of the intake path. When the engine is running at low speeds, a longer intake manifold allows the intake airflow to generate stronger inertia within the pipe, using this inertia to force more air into the cylinder before the intake valve closes, increasing the intake volume. Conversely, at high speeds, a shorter intake manifold reduces intake resistance, allowing air to enter the cylinder more quickly and improving charging efficiency.

[0022] The one-way conduit 404 includes a conduit and a one-way valve. The one-way valve is embedded in the surface of the conduit and is used to prevent gas in the gas tank 402 from being discharged through the conduit.

[0023] In this embodiment, when the manifold body 100 needs to be installed on the engine cylinder, align the manifold body 100 with the corresponding position on the engine cylinder, slide the bolt 200 into the pre-drilled holes on the manifold body 100 and the engine cylinder, and use an electric wrench to thread the nut 300 onto the bolt 200, so that the top of the nut 300 is pressed against the engine cylinder and the end of the bolt 200 is pressed against the end of the manifold body 100. At this time, thread the screw 401 into the nut 300 and the bolt 200, and align the small air pump with the opening of the one-way conduit 404. The small air pump is turned on, drawing in external gas, compressing it, and delivering it through the one-way conduit 404 to the air tank 402. Sufficient gas in the air tank 402 pushes the rubber rod 403 downwards, locking it into the screw 401, thus securing the bolt 200 and nut 300. Following the same method, the other bolts 200 and nuts 300 are installed on the manifold body 100 and the engine cylinder, and the bolts 200 and nuts 300 are locked, ensuring the manifold body 100 is tightly installed on the engine cylinder.

[0024] like Figure 4 As shown, an exhaust pipe 408 is fixedly connected to the inner wall of bolt 200. The bottom end of exhaust pipe 408 is connected to air groove 402. Rubber plugs 405 are threadedly connected to the surfaces of one-way conduit 404 and exhaust pipe 408. A first magnetic ring 406 is fixedly connected to the bottom end of rubber plug 405. A second magnetic ring 407 is fixedly connected to the surfaces of one-way conduit 404 and exhaust pipe 408. The first magnetic ring 406 and the second magnetic ring 407 attract each other with opposite poles. A nylon rope 411 is fixedly connected to the top end of rubber plug 405. The other end of nylon rope 411 is fixedly connected to the top end of bolt 200.

[0025] In this embodiment, in the initial state, one rubber plug 405 is threaded onto the exhaust pipe 408 to block the opening of the exhaust pipe 408. After injecting a certain amount of gas into the air groove 402, the air inlet of the small air pump is moved away from the one-way conduit 404. Another rubber plug 405 is threaded onto the one-way conduit 404 so that the surface of the rubber plug 405 is tightly attached to the inner wall of the one-way conduit 404, and the first magnetic ring 406 is magnetically attracted to the second magnetic ring 407.

[0026] like Figure 5 As shown, a rubber spring 409 is fixedly connected to the end of the rubber rod 403, and the top of the rubber spring 409 is fixedly connected to the inner top wall of the air groove 402.

[0027] like Figure 2 and Figure 4 As shown, two damping rings 412 are fixedly connected to the inner wall of the manifold body 100, and two anti-deviation blocks 410 are fixedly connected to the surface of the bolt 200. The surface of the anti-deviation block 410 is slidably connected to the inner wall of the damping ring 412.

[0028] In this embodiment, the bolt 200 slides into the damping ring 412, causing the anti-deviation block 410 to slide into the inner wall of the damping ring 412, so that the screw 401 can be accurately locked in the bolt 200.

[0029] Working principle: Pulling the rubber rod 403 upwards moves the screw 401 threaded into the nut 300 and bolt 200, loosening the restriction on the rubber rod 403. The elastic force of the rubber spring 409 pushes the rubber rod 403 downwards and locks it into the screw 401. Align the small air pump with the opening of the one-way conduit 404 and manually turn on the small air pump. The small air pump draws in external gas, compresses it, and delivers it through the one-way conduit 404 to the air groove 402. When there is sufficient gas in the air groove 402, it pushes the rubber rod 403 downwards and locks it into the screw 401, thereby locking the screw 401.

[0030] It should be noted that the manifold body 100, bolt 200, nut 300, screw 401, first magnetic ring 406, second magnetic ring 407 and damping ring 412 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
