[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following is a reference appendix. Figure 1-9 An intake assembly 100 according to an embodiment of the present invention is described.

[0046] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 According to an embodiment of the present invention, an intake assembly 100 is used in an engine system and includes an intake pipe 10 and a valve assembly 20.

[0047] Specifically, an intake passage 11 is formed inside the intake pipe 10; the valve assembly 20 is disposed in the intake pipe 10 and includes a valve shaft 21, a valve plate 22 and a drive member 23. The valve shaft 21 is disposed on one side of the intake pipe 10 in the radial direction and is rotatably connected to the intake pipe 10. The valve plate 22 is fixed on the valve shaft 21. The drive member 23 is used to drive the valve plate 22 to rotate through the valve shaft 21 to open and close the intake passage 11.

[0048] For example, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, valve shaft 21 extends vertically, valve plate 22 is plate-shaped, and valve shaft 21 is located on the right side of valve plate 22. Driving member 23 rotates to drive valve shaft 21 to rotate, and valve shaft 21 drives valve plate 22 to rotate. It should be explained that when valve plate 22 closes the intake passage 11, valve plate 22 extends horizontally; when valve plate 22 opens the intake passage 11, valve plate 22 extends longitudinally.

[0049] When the vehicle is running normally, the valve plate 22 opens the air intake passage 11, and gas flows from the air intake passage 11 to the engine to supply air to the engine. If there is water in front of the vehicle, the drive component 23 drives the valve shaft 21 to rotate, and the valve shaft 21 drives the valve plate 22 to close the air intake passage 11, thereby preventing liquid from entering the engine from the air intake passage 11.

[0050] The intake assembly 100 of the present invention has a valve shaft 21 located on one side of the intake pipe 10 in the radial direction. The valve plate 22 is flipped to form a flip-top type. When the valve plate 22 closes the intake passage 11, this flip-top type valve plate 22 can provide a robust physical barrier, directly blocking external water sources such as rainwater and splash water from entering the engine, thereby effectively protecting the engine. At the same time, compared with the butterfly valve assembly 20 in the prior art, it can effectively prevent the sealing failure caused by the rotation of the valve core. The intake assembly 100 of this application can effectively ensure the sealing effect of the valve assembly 20 on the intake passage 11, and effectively prevent the valve plate 22 from rotating due to liquid impact, thus effectively ensuring the sealing effect of the valve plate 22, thereby effectively preventing liquid from entering the engine and effectively ensuring the service life of the engine.

[0051] According to an embodiment of the present invention, the intake assembly 100 has a valve shaft 21 disposed on one side of the intake pipe 10 in the radial direction. When the valve plate 22 closes the intake passage 11, the valve plate 22 can provide a robust physical barrier to prevent external water from entering the engine, thereby effectively protecting the engine and ensuring its service life.

[0052] According to some embodiments of the present invention, with reference to Figure 3 , Figure 4 and Figure 6 The valve plate 22 is rotatably disposed within the intake passage 11. Thus, the valve plate 22 rotates within the intake passage 11, allowing it to open or close the intake passage 11. Simultaneously, it prevents external dust or solid particles from contacting the valve plate 22 and affecting its rotation, thereby ensuring long-term stable rotation. Furthermore, the valve plate 22 is made of plastic, which is inexpensive and suitable for mass production.

[0053] According to some optional embodiments of the present invention, refer to Figure 4 , Figure 5 and Figure 6 The intake pipe 10 includes a first pipe section 101 and a second pipe section 102 connected in the extending direction of the intake pipe 10. At the connection position of the first pipe section 101 and the second pipe section 102, the cross-sectional area of ​​the first pipe section 101 is smaller than the cross-sectional area of ​​the second pipe section 102. The valve plate 22 is disposed in the second pipe section 102 and is located at the connection position of the first pipe section 101 and the second pipe section 102.

[0054] In this way, the cross-sectional area of ​​the first pipe section 101 is smaller than that of the second pipe section 102. The valve plate 22 moves within the second pipe section 102, which ensures that the valve plate 22 can rotate normally. At the same time, the rotation of the valve plate 22 can directly close the first pipe section 101 with a smaller cross-section, thereby ensuring that the valve assembly 20 can effectively close the intake passage 11 and prevent liquid from entering the engine.

[0055] For example, such as Figure 4 , Figure 5 and Figure 6 As shown, the first pipe section 101 is located in front of the second pipe section 102. The cross-sectional area of ​​the first pipe section 101 is smaller than that of the second pipe section 102. The valve plate 22 moves within the second pipe section 102 and is located at the connection between the first pipe section 101 and the second pipe section 102.

[0056] According to some optional embodiments of the present invention, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The end of the first pipe section 101 that is opposite to the second pipe section 102 (e.g.) Figure 1The front end of the first pipe section 101 shown is formed as the outlet end 12 of the air inlet pipe 10, and the end of the second pipe section 102 opposite to the first pipe section 101 (as shown) Figure 1 The rear end of the second pipe section 102 shown is formed as the air intake end 13 of the air intake pipe 10. When the valve plate 22 closes the air intake passage 11, it blocks the end of the first pipe section 101 facing the second pipe section 102 (e.g., Figure 1 (The rear end of the first pipe section 101 shown) When the valve plate 22 opens the air intake passage 11, it is located in the second pipe section 102.

[0057] Thus, the outlet end 12 is located at the front end of the first pipe section 101, facilitating the connection between the intake pipe 10 and the engine. Simultaneously, the intake end 13 is located at the rear end of the second pipe section 102, allowing outside air to easily enter the intake passage 11. Furthermore, the valve plate 22, at the connection point between the first pipe section 101 and the second pipe section 102, can directly block one end of the first pipe section 101, thereby facilitating the valve plate 22's sealing of the intake passage 11.

[0058] For example, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the front end of the first pipe section 101 is formed as the air outlet 12, and the rear end of the second pipe section 102 is formed as the air inlet 13. The valve plate 22 moves within the second pipe section 102. When the valve plate 22 closes the air inlet channel 11, it blocks the rear end of the first pipe section 101.

[0059] According to some embodiments of the present invention, with reference to Figure 1 , Figure 4 and Figure 6 The end of the second pipe section 102 that is connected to the first pipe section 101 (e.g. Figure 1 The front end of the second pipe section 102 shown has a square cross-section, and the end of the first pipe section 101 connected to the second pipe section 102 (as shown) Figure 1 The cross-section of the rear end of the first pipe section 101 shown is circular or square.

[0060] This configuration ensures that the first pipe section 101 and the second pipe section 102 can be connected normally, thus making the intake pipe 10 a single unit and ensuring the integrity of the intake channel 11. At the same time, the square second pipe section 102 ensures that the valve plate 22 can rotate normally within the second pipe section 102, and the circular first pipe section 101 facilitates the valve plate 22 to block the intake channel 11.

[0061] For example, such as Figure 1 , Figure 4 and Figure 6 As shown, the front end of the second pipe section 102 has a square cross-section, and the rear end of the first pipe section 101 has a circular cross-section.

[0062] According to some embodiments of the present invention, with reference to Figure 3 , Figure 4 and Figure 5 The valve assembly 20 includes a seal 24, which extends annularly along the circumference of the valve plate 22. The valve plate 22 closes the intake passage 11, and the seal 24 seals against the inner wall of the intake passage 11. Therefore, by providing the seal 24, the sealing effect of the valve plate 22 in closing the intake passage 11 can be improved, thereby effectively preventing external water from entering the engine. Simultaneously, the annular shape of the seal 24 can seal the intake passage 11 circumferentially, further preventing external water from entering the engine.

[0063] Furthermore, the seal 24 is made of rubber, which can not only ensure the sealing effect of the seal 24, but also reduce the production cost of the seal 24 and facilitate mass production.

[0064] According to some optional embodiments of the present invention, refer to Figure 4 , Figure 5 and Figure 6 One side surface of valve plate 22 (e.g.) Figure 4 The front surface of the valve plate 22 (shown) has a raised boss 221. The seal 24 is fitted onto the boss 221. When the valve plate 22 closes the air intake passage 11, the boss 221 engages within the first pipe section 101, and the seal 24 abuts against the inner circumferential wall of the first pipe section 101. Therefore, the boss 221 facilitates the engagement of the seal 24 with the valve plate 22, reducing the difficulty of assembly and improving efficiency. Simultaneously, the seal 24 being fitted onto the boss 221 ensures the fixing strength between the seal 24 and the boss 221, effectively preventing separation of the seal 24 from the valve plate 22. Furthermore, the boss 221 is located on the side of the valve plate 22 facing the first pipe section 101. When the valve plate 22 rotates, the seal 24 can directly abut against the inner circumferential wall of the first pipe section 101, thus ensuring the sealing effect of the seal 24.

[0065] For example, such as Figure 4 , Figure 5 and Figure 6 As shown, taking the state when the valve plate 22 closes the intake passage 11 as an example, the front surface of the valve plate 22 is provided with a protruding boss 221, the sealing member 24 is sleeved on the boss 221, and the sealing member 24 abuts against the inner peripheral wall of the first pipe section 101.

[0066] According to some optional embodiments of the present invention, refer to Figure 4 and Figure 5The outer peripheral surface of the boss 221 is provided with a recessed mounting groove, and the seal 24 is disposed in the mounting groove. This can further improve the fixing strength between the seal 24 and the boss 221, and effectively prevent the seal 24 from separating from the boss 221.

[0067] For example, such as Figure 4 and Figure 5 As shown, the outer peripheral surface of the boss 221 is provided with a mounting groove that is recessed radially inward along the air intake channel 11. The mounting groove extends in a ring shape along the circumference of the boss 221, and the seal 24 is located in the mounting groove.

[0068] According to some embodiments of the present invention, with reference to Figure 1 , Figure 4 and 5 The outer peripheral surface of the seal 24 is provided with a raised sealing lip 241. The sealing lip 241 extends in a ring shape along the circumference of the seal 24, and in the protruding direction of the sealing lip 241, the sealing lip 241 extends obliquely toward the side where the second pipe section 102 is located. Thus, the sealing lip 241 can abut against the cavity wall of the first pipe section 101, thereby further improving the sealing effect of the seal 24. At the same time, when the valve plate 22 closes the air inlet passage 11, if liquid flows into the valve plate 22, the liquid pressure will push the sealing lip 241 to deform further toward the inner peripheral wall of the first pipe section 101, thereby further sealing the gap between the valve plate 22 and the first pipe section 101, thus ensuring the sealing effect of the seal 24.

[0069] For example, such as Figure 1 , Figure 4 and Figure 5 As shown, the sealing lip 241 is provided on the outer peripheral surface of the seal 24 and extends in an annular shape along the circumference of the seal 24. The seal 24 extends obliquely toward the second section in a direction away from the center of the seal 24, so that the cross-section of the seal 24 is formed into a V-shaped structure that opens toward the second pipe section 102. When liquid flows into the opening on the open side of the seal 24, the liquid pressure will squeeze the sealing lip 241 to abut against the inner peripheral wall of the first pipe section 101, thereby ensuring the sealing effect of the seal 24.

[0070] According to some embodiments of the present invention, with reference to Figure 1 , Figure 4 and Figure 5 A shaft hole (not shown in the figure) is formed at the connection position of the first pipe section 101 and the second pipe section 102, and both ends of the valve shaft 21 (such as...) Figure 4The upper and lower ends of the valve shaft 21 shown are rotatably disposed within the shaft hole, and the drive member 23 is arranged on the outside of the intake pipe 10. Therefore, the shaft hole facilitates the arrangement of the valve shaft 21 and ensures that the valve shaft 21 can rotate relative to the intake pipe 10, thus ensuring the normal function of the valve assembly 20. Furthermore, the drive member 23, being located on the outside of the intake pipe 10, does not occupy the internal space of the intake channel 11, thereby ensuring the gas flow cross-section of the intake channel 11. Its external location also provides ample operating space, facilitating the installation and mating of the drive member 23 with the intake pipe 10.

[0071] For example, such as Figure 1 , Figure 4 and Figure 5 As shown, a shaft hole is provided at the connection position of the first pipe section 101 and the second pipe section 102. The upper and lower ends of the valve shaft 21 are rotatably disposed in the shaft hole. The driving component 23 is disposed on the outside of the air intake pipe 10 and connected to the upper end of the valve shaft 21.

[0072] According to some optional embodiments of the present invention, refer to Figure 4 and Figure 5 The intake assembly 100 includes a bushing 30, which is disposed within a shaft hole and fitted onto the valve shaft 21. The bushing 30 allows the valve shaft 21 to rotate relative to the intake pipe 10 within the shaft hole. Therefore, the contact point between the valve shaft 21 and the shaft hole is at the bushing 30, reducing the contact area between the valve shaft 21 and the shaft hole wall, thus ensuring smooth rotation of the valve shaft 21. Furthermore, in the event of sudden conditions such as icing causing the bushing 30 to stick to the shaft hole wall, the relatively small contact area between the bushing 30 and the shaft hole allows the drive component 23 to output only a small torque to separate the bushing 30 from the shaft hole wall. Therefore, in special circumstances like icing, the torque required for the drive component 23 to break the ice is reduced, ensuring the normal functioning of the intake assembly 100.

[0073] Furthermore, the bushing 30 is made of plastic with self-lubricating properties. When the valve plate 22 rotates, it can play a lubricating role, thereby reducing the friction between the bushing 30 and the wall of the shaft hole, and thus ensuring the smooth rotation of the valve plate 22.

[0074] According to some optional embodiments of the present invention, refer to Figure 1 , Figure 4 and Figure 6 The first pipe section 101 and the second pipe section 102 are separate components. The end face of the first pipe section 101 facing the second pipe section 102 (e.g.) Figure 1 The rear end face of the first pipe segment 101 shown is provided with a first groove (not shown in the figure), and the end face of the second pipe segment 102 facing the first pipe segment 101 (as shown in the figure) is provided with a first groove. Figure 1The front end face of the second pipe section 102 shown is provided with a second groove (not shown in the figure), and the first groove and the second groove cooperate to enclose the shaft hole.

[0075] In this way, the first pipe section 101 and the second pipe section 102 of the split parts can facilitate the processing of the air intake pipe 10, thereby saving the processing time of the air intake pipe 10 and improving the processing efficiency. At the same time, the shaft hole is formed by the cooperation of the first groove and the second groove, thereby reducing the processing difficulty of the shaft hole and facilitating the processing of the shaft hole.

[0076] For example, such as Figure 1 , Figure 4 and Figure 6 As shown, the rear end face of the first pipe section 101 is provided with a first groove, which is recessed forward, and the front end face of the second pipe section 102 is provided with a second groove, which is recessed backward. The first groove and the second groove are joined together in the front-rear direction to form a shaft hole extending in the vertical direction.

[0077] According to some embodiments of the present invention, with reference to Figure 7 , Figure 8 and Figure 9 The driving component 23 is a stepper motor. Therefore, the stepper motor can save response time, improve response speed, and improve control accuracy, thereby enabling precise control of the opening and closing angle of the valve plate 22.

[0078] Furthermore, such as Figure 7 , Figure 8 and Figure 9 As shown, the drive unit 23 includes: a first cover 231, a second cover 232, a waterproof ring 233, a rotor 234, a stator 235, a transmission gear set 236, an output shaft gear 237, and a control board 238. The first cover 231 and the second cover 232 are made of plastic and are connected by laser welding to ensure airtightness. The outer layer of the waterproof ring 233 is made of rubber and the inner layer is made of metal. The waterproof ring 233 is interference-fitted into the first cover 231 and serves to seal the output shaft gear 237. The output shaft gear 237 is made of plastic and has a star-shaped hole in its center. The output shaft gear 237 drives the valve shaft 21 to rotate by cooperating with the upper end of the valve shaft 21. The transmission gear set 236 is made of plastic and serves to amplify torque. The transmission gear set 236 adopts a spur gear design, which can improve the transmission efficiency of the gear and reduce torque loss. The control plate 238 is mainly used to finely adjust the opening and closing position of the valve plate 22, thereby adjusting the air intake flow section of the air intake channel 11.

[0079] According to some embodiments of the present invention, with reference to Figure 1 and Figure 2The intake assembly 100 includes a damper 40, which is disposed on the outside of the intake pipe 10. The intake pipe 10 is adapted to be connected to the vehicle body through the damper 40. Thus, the damper can both fix the intake pipe 10 to the vehicle body and prevent the vibration of the vehicle body from being transmitted to the intake pipe 10, thereby ensuring the stability of the connection between the intake pipe 10 and the engine.
