Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0017] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0018] See Figure 1 , Figure 2 and Figure 3 This utility model provides an engine intake pipe, which includes an intake pipe body 4 and a temperature control component disposed on the intake pipe body 4. The temperature control component preheats the cold air entering the intake pipe body 4 during cold starts to ensure aerodynamic performance. The temperature control component includes: The housing 2, which is fitted onto the outside of the intake pipe body 4, protects the internal components of the control assembly and ensures its service life. A heating rod 6 is installed inside the housing 2 to heat the gas inside the intake manifold body 4. The heating rod 6 passes through the portion of the intake manifold body 4 located inside the housing 2, ensuring that the housing 2 can protect the heating rod 6. The heating rod 6 extends into the intake manifold body 4 during engine cold start, thereby heating the gas inside the intake manifold body 4 at this time to ensure the cold start effect. When the engine is running normally, the heating rod 6 retracts into the housing 2, ensuring that it no longer works through the housing 2, further optimizing the energy structure.

[0019] In one embodiment, see Figure 4 and Figure 5 To ensure the control and heating effect of the heating rod 6, a sliding hole is provided on the air intake pipe body 4. The heating rod 6 is slidably connected to the inside of the sliding hole, ensuring that the heating rod 6 can switch between being extended into the air intake pipe body 4 and retracted, thus ensuring the control of the position of the heating rod 6. The end of the heating rod 6 is provided with a connecting contact 61, and the inside of the housing 2 is provided with a conductive contact 3. When the heating rod 6 is extended into the air intake pipe, it connects with the conductive contact 3. Through the connection between the conductive contact 3 and the connecting contact 61 at this time, the power supply effect of the heating rod 6 is realized, thereby realizing the heating effect of the heating rod 6.

[0020] Furthermore, to ensure the connection effect between the conductive contact 3 and the connecting contact 61, the conductive contact 3 extends from the outside of the housing 2 to the inside of the housing 2, ensuring that the internal contact portion 9 can be powered by the external power supply, thereby ensuring the normal power supply effect of the conductive contact 3. At the same time, the conductive contact 3 is provided with the contact portion 9 inside the housing 2. The contact portion 9 is correspondingly provided with the connecting contact 61. When the connecting contact 61 contacts and abuts the contact portion 9, the heating rod 6 is connected to the conductive contact 3 and energized.

[0021] Specifically, the abutment part 9 is made of an elastic material, such as brass or other elastic metal or alloy materials, to ensure the elasticity and conductivity of the abutment part 9. The abutment part 9 has a long plate structure, and the strip-shaped plate structure can ensure both conductivity and elasticity. An insulating material is provided between the abutment part 9 and the housing 2 to prevent short circuits between the abutment part 9 and the housing 2, which would cause conductivity between the abutment part 9 and the housing 2, resulting in the housing 2 becoming electrified and affecting the safety of the engine.

[0022] In one embodiment, in order to control the position of the heating rod 6, a control coil 7 is provided around the outer ring of the sliding hole, and a magnetic part 62 is provided on the top of the heating rod 6. The magnetic part 62 can be a structure that is sleeved on the outside of the heating rod 6 to ensure that the control coil 7 is energized and de-energized to control the position of the heating rod 6 and compress the thrust spring 8. The control coil 7 and the magnetic part 62 cooperate to control the heating rod 6 to slide up and down. A limiting flange is provided on the top of the heating rod 6, and a thrust spring 8 is sleeved on the outside of the heating rod 6. The thrust spring abuts against the top of the sliding hole and the bottom of the limiting flange. The connecting contact 61 is provided on the side of the limiting flange.

[0023] When using, combine Figures 1-5 The intake port 5 and exhaust port 1 of the intake manifold body 4 are connected to the corresponding positions on the engine. The temperature control component is set at the front end of the fuel supply. During use, the ECU and other control modules detect whether it is in a cold start state. When a cold start occurs, the control coil 7 is powered first. When the control coil 7 is energized, it generates a magnetic field, which pushes the heating rod 6 into the interior of the intake manifold body 4. At the same time, the conductive contact 3 and the connecting contact 61 are energized, and the heating rod 6 is energized to heat the gas inside the intake manifold body, thus achieving the gas preheating effect during the cold start process. After the engine starts, the control coil 7 is de-energized. Under the action of the thrust spring 8, the heating rod 6 retracts into the interior of the housing 2, without affecting the gas flow inside the intake manifold body 4, thus optimizing energy.

[0024] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
