Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to a valve train system and a vehicle. Background Technology

[0002] Variable valve timing (VVT) is an important technology for improving engine power, fuel economy, and emissions performance. Traditional engines typically use gears on the crankshaft to drive a timing chain, which in turn drives the camshaft. The camshaft has multiple cams that control the opening and closing of the intake and exhaust valves based on the camshaft's rotation angle. This overall mechanical transmission and valve timing structure is complex and prone to generating significant mechanical noise during transmission due to gear meshing.

[0003] In addition, some camshaft valve trains need to adjust the opening and closing angles of the valves to improve engine combustion efficiency, and hydraulic or electronic control modules need to be added to the valve train. This increases costs, and because the hydraulic or electronic control modules have limited adjustment of the intake and exhaust angles, they cannot keep the engine at its best combustion efficiency at all times. Summary of the Invention

[0004] The purpose of this application is to provide a valve train system and vehicle that have the characteristics of simple structure and low noise.

[0005] A first aspect of this application provides a valve train system applied to a vehicle, the valve train system comprising:

[0006] A cylinder head is disposed on the combustion chamber of the vehicle. The cylinder head has an air intake port and an exhaust port that are spaced apart from each other. Both the air intake port and the exhaust port are connected to the combustion chamber and the outside of the combustion chamber.

[0007] An intake assembly and an exhaust assembly are provided, both of which are located on the side of the cylinder head away from the combustion chamber. The intake assembly includes a connected intake baffle and a first magnetic element, the intake baffle corresponding to the intake port. The exhaust assembly includes a connected exhaust baffle and a second magnetic element, the exhaust baffle corresponding to the exhaust port.

[0008] An electromagnetic component is disposed on the side of the cylinder head away from the combustion chamber. The electromagnetic component includes an input terminal, a first terminal, and a second terminal. The first terminal and the second terminal are respectively disposed opposite to the first magnetic component and the second magnetic component. The first terminal and the second terminal are capable of having opposite magnetism when current is input to the input terminal, and the first terminal and the second terminal are capable of having no magnetism when no current is input to the input terminal.

[0009] Wherein, the first magnetic element has the same magnetism toward the first end as the second magnetic element has the same magnetism toward the second end; when the first end and the second end have opposite magnetism: the air intake baffle opens or closes the air intake under the action of the first end and the first magnetic element, while the exhaust baffle closes or opens the exhaust port under the action of the second end and the second magnetic element;

[0010] When the first end and the second end are not magnetic: the air intake block and the exhaust block respectively close the air intake port and the exhaust port.

[0011] In one exemplary embodiment of this application, the air intake baffle is capable of sliding at the air intake under the action of the first end and the first magnetic element; and / or

[0012] The exhaust baffle can slide at the exhaust port under the action of the second end and the second magnetic element.

[0013] In one exemplary embodiment of this application, the intake assembly / exhaust assembly further includes a moving rod, an elastic element, a limiting shell, and a limiting block. The limiting block is fixedly disposed on the side of the cylinder head away from the combustion chamber. The limiting block has a through hole. The moving rod passes through the through hole and extends along the moving path of the intake block / exhaust block. The limiting shell and the intake block / exhaust block are respectively disposed on both sides of the limiting block. The intake block / exhaust block is disposed on the side of the moving rod away from the first end / second end. The limiting shell is disposed on the side of the moving rod facing the first end / second end.

[0014] The limiting shell includes a first placement position and a second placement position. The opening directions of the first placement position and the second placement position are opposite. The opening direction of the first placement position is towards the first end / second end. The first magnetic element / second magnetic element is disposed in the first placement position. The opening direction of the second placement position is towards the limiting block. The second placement position is connected to the moving rod. The elastic element is sleeved on the moving rod, and one end of the elastic element abuts against the bottom wall of the second placement position, and the other end abuts against the side of the limiting block facing the electromagnetic element.

[0015] When the magnetism of the first magnetic component / second magnetic component toward the first end / second end is the same as that of the first end / second end, the first magnetic component / second magnetic component is pushed to move away from the first end / second end, the elastic component is compressed, so as to drive the moving rod to move away from the first end / second end, and the air intake block / exhaust block slides away from the first end / second end under the action of the moving rod, so as to open the air intake port / exhaust port;

[0016] When the magnetism of the first magnetic component / second magnetic component toward the first end / second end is opposite to that of the first end / second end, under the action of the limiting block, the air intake block / exhaust block is maintained at the air intake / exhaust port to block the air intake / exhaust port.

[0017] In one exemplary embodiment of this application, the opening of the first placement position and the bottom wall of the second placement position are located on the same plane.

[0018] In one exemplary embodiment of this application, the cylinder head includes a cylinder head body and a support portion. The cylinder head body is provided with the air intake port and the exhaust port. The cylinder head body covers the combustion chamber, and the support portion is provided on the side of the cylinder head body away from the combustion chamber.

[0019] The electromagnetic component is located on the side of the support portion away from the cylinder head body. The support portion is provided with a limiting groove, and the moving rod is inserted into the limiting groove and can slide within the limiting groove.

[0020] In one exemplary embodiment of this application, the valve train further includes a cylinder head cover, which is disposed on the side of the cylinder head away from the combustion chamber and forms a receiving chamber with the cylinder head. The intake assembly and the exhaust assembly are both disposed in the receiving chamber.

[0021] The electromagnetic component includes an electromagnetic body and an electromagnetic coil. The two ends of the electromagnetic body are the first end and the second end, respectively. The electromagnetic body is located on the side of the support portion away from the cylinder head. The electromagnetic coil is wound around the electromagnetic body and has an access end. A portion of the access end is located inside the receiving cavity, and another portion is located outside the receiving cavity.

[0022] In one exemplary embodiment of this application, the limiting block is fixedly disposed within the receiving cavity;

[0023] The cylinder head cover has a slot on the inner wall facing the cylinder head, and the end of the limiting block away from the cylinder head is inserted into the slot.

[0024] In one exemplary embodiment of this application, the limiting shell and the moving rod are interference-fitted; and / or

[0025] The cylinder head is axisymmetric, and the intake assembly and the exhaust assembly are symmetrically arranged with respect to the axisymmetric line of the cylinder head.

[0026] In one exemplary embodiment of this application, the gas distribution system further includes:

[0027] Sensor, including signal output terminal;

[0028] A controller, electrically connected to the signal output terminal, is capable of outputting a control signal according to the signal input to the signal output terminal;

[0029] A current controller includes a signal input port, a current input port, and a transmission port. The signal input port is electrically connected to the output port of the controller to receive the control signal. The transmission port is electrically connected to the access terminal. The current controller can transmit the current signal transmitted by the current input port to the access terminal according to the control signal. The first terminal and the second terminal have opposite magnetic properties. The first terminal and the second terminal are non-magnetic when there is no current input at the current input port.

[0030] A second aspect of this application provides a vehicle including an engine and a valve train system as described in any of the preceding claims, the engine including a combustion chamber and a cylinder head covering the combustion chamber.

[0031] The proposed solution has the following beneficial effects:

[0032] This application includes a valve train system, which comprises a cylinder head, an intake assembly, an exhaust assembly, and an electromagnetic component. The cylinder head is mounted on the combustion chamber of the engine and has an intake port and an exhaust port. The intake assembly includes an intake baffle and a first magnetic component, and the exhaust assembly includes an exhaust baffle and a second magnetic component. The electromagnetic component includes a connection terminal, a first terminal, and a second terminal. When current is applied to the connection terminal, the first and second terminals have opposite magnetic properties; when no current is applied, the first and second terminals are non-magnetic. The first magnetic component exhibits the same magnetic property towards its first terminal as the second magnetic component exhibits the same magnetic property towards its second terminal. When current is applied to the connection terminal, the intake baffle opens / closes the intake port under the action of the first magnetic component and the first terminal, while the exhaust baffle closes / opens the exhaust port under the action of the second magnetic component and the second terminal, thereby completing the alternation of intake and exhaust in the engine combustion chamber. In other words, this application utilizes an electromagnetically driven valve train system to replace the traditional mechanical transmission drive structure, reducing mechanical transmission components, saving space occupied by the valve train system, and also reducing the noise generated by the mechanical transmission drive structure, resulting in excellent noise, vibration, and harshness performance. Furthermore, the electromagnetically driven valve train system allows for alternating intake and exhaust in the combustion chamber, ensuring independent operation of intake and exhaust, and precisely controlling the engine's opening and closing at any crankshaft angle, allowing the engine to continuously achieve efficient combustion.

[0033] In addition, the present application also includes vehicles. This valve train is installed on the combustion chamber of the vehicle, which can improve the combustion efficiency of the vehicle engine combustion chamber and play an important role in promoting energy conservation and emission reduction. Moreover, the above-mentioned valve train structure can make the engine less noisy during operation and have good noise, vibration, and harshness (NVH) performance.

[0034] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0055] Example 1

[0056] Embodiment 1 of this application provides a valve train system 10, which can be applied to high-efficiency engines and is suitable for use in hybrid engines, but is not limited thereto. This valve train system 10 works in conjunction with the engine's combustion chamber, enabling gas exchange within the combustion chamber. This valve train system 10 does not require a complex camshaft valve train structure, allowing the valve lift, engine crankshaft angle, and valve opening duration to operate independently. It precisely controls the engine's opening and closing at any crankshaft angle, ensuring continuous high-efficiency combustion. It offers advantages such as convenient control, simple structure, and fast response.

[0057] Among them, see Figure 1 and Figure 2 As shown, the gas distribution system 10 in this application includes:

[0058] The cylinder head 100 is located on the combustion chamber of the vehicle. The cylinder head 100 has an air intake 101 and an exhaust 102 that are spaced apart from each other. The air intake 101 connects the combustion chamber and the outside of the combustion chamber, and the exhaust 102 connects the combustion chamber and the outside of the combustion chamber, so as to enable gas exchange between the combustion chamber and the outside of the combustion chamber.

[0059] The intake assembly 200 is located on the side of the cylinder head 100 away from the combustion chamber. The intake assembly 200 includes an intake baffle 201 and a first magnetic element 202. The intake baffle 201 corresponds to the intake port 101. The first magnetic element 202 is connected to the intake baffle 201 and has two magnetic poles facing different sides.

[0060] The exhaust assembly 300 is located on the side of the cylinder head 100 away from the combustion chamber, and the exhaust assembly 300 and the intake assembly 200 are spaced apart from each other. The exhaust assembly 300 includes an exhaust baffle 301 and a second magnetic element 302. The exhaust baffle 301 corresponds to the exhaust port 102. The second magnetic element 302 is connected to the exhaust baffle 301 and has two magnetic poles facing different sides.

[0061] An electromagnetic component 400 is located on the side of the cylinder head 100 away from the combustion chamber. It includes an input terminal 401, a first terminal 402, and a second terminal 403. The first terminal 402 corresponds to a first magnetic component 202 in the intake assembly 200, meaning the first terminal 402 corresponds to one of the magnetic poles of the first magnetic component 202. The second terminal 403 corresponds to a second magnetic component 302 in the exhaust assembly 300, meaning the second terminal 403 corresponds to one of the magnetic poles of the second magnetic component 302. The first terminal 402 and the second terminal 403 only exhibit magnetism when current is input to the input terminal 401, and when current is input to the input terminal 401, the first terminal 402 and the second terminal 403 have opposite magnetic properties. When no current is input to the input terminal 401, the first terminal 402 and the second terminal 403 do not exhibit magnetism.

[0062] In this configuration, the magnetic pole of the first magnetic element 202 facing the first end 402 is identical to that of the second magnetic element 302 facing the second end 403. Therefore, when one of the first magnetic element 202 or the second magnetic element 302 is attracted, the other is repelled, allowing the air inlet 101 and the exhaust outlet 102 to alternately intake and exhaust air. When the first end 402 and the second end 403 have opposite magnetic properties, the air intake baffle 201 opens / closes the air inlet 101 under the action of the first end 402 and the first magnetic element 202, while the exhaust baffle 301 closes / opens the exhaust outlet 102 under the action of the second end 403 and the second magnetic element 302, thus achieving alternating air intake and exhaust. In other words, there are three ways to achieve the proposed solution. The first is that when the air inlet 101 is open, the exhaust port 102 is closed. The second is that when the exhaust port 102 is open, the air inlet 101 is closed. The third is that both the air inlet 101 and the exhaust port 102 are closed, so that there is no gas exchange between the combustion chamber and the outside of the combustion chamber, and the combustion chamber is in a state of gas compression or isentropic work (that is, when the first end 402 and the second end 403 are not magnetic).

[0063] This application's solution replaces the traditional mechanical transmission drive structure of valve train with an electromagnetic valve train system 10, significantly reducing mechanical transmission components, improving space utilization, and eliminating the mechanical noise of cam drives in traditional mechanical transmission drive structures. It also exhibits excellent noise, vibration, and harshness (NVH) performance. Furthermore, the valve train system 10 in this application's solution has the advantages of independent operation of valve lift, engine crankshaft angle, and valve opening duration, convenient control, simple structure, and fast response speed, enabling the engine to maintain efficient combustion and higher fuel efficiency.

[0064] In the embodiments of this application, see Figure 1 and Figure 2 As shown, this electromagnetic component 400 can adopt a structure such as an electromagnetic coil 405, which includes an electromagnetic body 404 and an electromagnetic coil 405. The electromagnetic coil 405 is wound around the periphery of the electromagnetic body 404. The two opposite ends of the electromagnetic body 404 are a first end 402 and a second end 403, respectively. The electromagnetic coil 405 is provided with an input end 401. When current is input to the input end 401, the magnetism of the first end 402 and the second end 403 can be determined according to Ampere's law.

[0065] For example, the access terminal 401 has a first access point and a second access point. When current is connected to the first access point and current is output from the second access point, the first terminal 402 is the north pole (N pole) and the second terminal 403 is the south pole (S pole). When current is connected to the second access point and current is output from the first access point, the first terminal 402 is the south pole (S pole) and the second terminal 403 is the north pole (N pole).

[0066] That is, by changing the direction of the current flow, the magnetism of the first end 402 and the second end 403 in the electromagnetic body 404 is changed. The following description will be based on the following scenarios: when a positive current is input at the input end 401, the first end 402 is the north pole (N pole) and the second end 403 is the south pole (S pole); when a reverse current is input at the input end 401, the first end 402 is the south pole (S pole) and the second end 403 is the north pole (N pole).

[0067] It should be noted that the present application solution can simultaneously control the opening and closing of the air intake 101 and exhaust port 102 of each combustion chamber in the engine through a single electromagnetic body 404, and can precisely control the start and stop of the engine at any angle of crankshaft rotation.

[0068] Furthermore, the use of a single electromagnetic body 404 reduces the number of structural components, resulting in a simpler structure, less electrical energy required during the operation of the electromagnetic component 400, and lower production and operating costs.

[0069] Of course, in some embodiments, the electromagnetic component 400 may also include two electromagnetic bodies 404, that is, the intake component 200 corresponds to one electromagnetic body 404 and the exhaust component 300 corresponds to one electromagnetic body 404. The opening and closing of the intake port 101 and the exhaust port 102 are controlled by the electromagnetic body 404, the first electromagnetic component 400, the second electromagnetic component 400, the exhaust block 301 and the intake block 201.

[0070] In this design, one magnetic pole of the first magnetic element 202 / second magnetic element 302 is positioned opposite to the first end 402 / second end 403, while the other magnetic pole is located at the end of the first magnetic element 202 / second magnetic element 302 furthest from the first end 402 / second end 403. This means the magnetic pole furthest from the first end 402 / second end 403 is not affected by the magnetic pole of the first end 402 / second end 403. When the first end 402 / second end 403 is magnetic, it will repel or attract the first magnetic element 202 / second magnetic element 302, thereby controlling the intake baffle 201 / exhaust baffle 301 to open or close the intake port 101 / exhaust port 102.

[0071] It is worth mentioning that the magnetic pole of the first magnetic component 202 facing the first end 402 can be either the North Pole (N pole) or the South Pole (S pole), without any specific limitation here.

[0072] For example, the magnetic pole of the first magnetic element 202 facing the first end 402 is the north pole (N pole), and the magnetic pole of the first magnetic element 202 away from the first end 402 is the south pole (S pole):

[0073] When a positive current is input to the input terminal 401, since the magnetic pole of the first magnetic element 202 near the first end 402 is the north pole (N pole) of the first end 402, the two repel each other, which opens the intake port 101 of the control intake block 201, and the gas outside the combustion chamber enters the combustion chamber through the intake port 101 for combustion; while since the second end 403 is the south pole (S pole), and the magnetic pole of the second magnetic element 302 near the second end 403 is the north pole (N pole), the two attract each other, and the exhaust block 301 remains blocked at the exhaust port 102, preventing the gas inside the combustion chamber from exchanging with the gas outside the combustion chamber through the exhaust port 102.

[0074] When a reverse current is input to the input terminal 401, the magnetic pole of the first magnetic element 202 near the first end 402 is the south pole (S pole), and the first end 402 is the north pole (N pole). The two attract each other, and the intake baffle 201 still blocks the intake port 101, preventing the gas outside the combustion chamber from entering the combustion chamber through the intake port 101 for combustion. However, since the magnetic poles of the second end 403 and the second magnetic element 302 near the second end 403 are both north poles (N pole), the two repel each other, opening the exhaust port 102, allowing the gas inside the combustion chamber to exchange with the gas outside the combustion chamber.

[0075] It is understandable that the magnetic pole of the first magnetic element 202 facing the first end 402 is the south pole (S pole), and the magnetic pole of the first magnetic element 202 away from the first end 402 is the north pole (N pole), which is the same principle as described above, and will not be elaborated further here.

[0076] In this embodiment of the application, the air intake block 201 can slide at the air intake 101 under the action of the first end 402 and the first magnetic element 202 to open or close the air intake 101; while the exhaust block 301 can slide at the exhaust port 102 under the action of the second end 403 and the second magnetic element 302 to open or close the exhaust port 102.

[0077] In some embodiments, the air intake baffle 201 can be flipped or folded at the air intake 101 under the action of the first end 402 and the first magnetic element 202, thereby opening or closing the air intake 101. The exhaust baffle 301 can also be flipped or folded at the exhaust port 102 under the action of the second end 403 and the second magnetic element 302, thereby opening or closing the exhaust port 102.

[0078] It should be noted that in some other embodiments, other methods of opening or closing the air inlet 101 and the exhaust outlet 102 may also be used.

[0079] Furthermore, in some embodiments, the intake baffle 201 and the exhaust baffle 301 may open or close the intake port 101 and the exhaust port 102 in different ways. For example, the intake baffle 201 may open or close the intake port 101 by sliding, and the exhaust baffle 301 may open or close the exhaust port 102 by flipping or folding.

[0080] It is worth mentioning that, in order to ensure the combustion efficiency of the combustion chamber, one of the air intake 101 and the exhaust port 102 is in the open state, while the other is in the closed state. That is, the air intake baffle 201 and the exhaust baffle 301 alternately open or block the air intake 101 and the exhaust port 102.

[0081] In the embodiments of this application, see Figure 2 As shown, the cylinder head 100 is an axisymmetric figure, comprising a cylinder head body 103 and a support portion 104. An intake assembly 200 and an exhaust assembly 300 are disposed on the surface of the cylinder head body 103 away from the combustion chamber, and the intake assembly 200 and exhaust assembly 300 are axisymmetric with respect to the line of symmetry of the cylinder head 100, that is, the intake assembly 200 and exhaust assembly 300 are respectively disposed on both sides of the line of symmetry of the cylinder head body 103. The cylinder head body 103 is pointed, and its cross-sectional area gradually increases from the top to the bottom of the cylinder head body 103. The intake assembly 200 and exhaust assembly 300 are disposed on opposite sides of the cylinder head body 103, and the support portion 104 is disposed on the side of the cylinder head body 103 away from the combustion chamber, and the support portion 104 is located at the top of the cylinder head body 103.

[0082] In the embodiments of this application, please continue to refer to Figure 2 As shown, the support portion 104 includes a support position 110 and a connecting position 111 connected to each other. The support position 110 is connected to the cylinder head body 103 through the connecting position 111. From the top to the bottom of the cylinder head body 103, the cross-sectional area of ​​the support position 110 gradually increases, while the cross-sectional area of ​​the connecting position 111 gradually decreases. The support position 110 is generally arched. An electromagnetic component 400 is fixedly provided on the side of the support position 110 away from the combustion chamber. The shape of the electromagnetic component 400 is the same as that of the support position 110. The first end 402 and the second end 403 of the electromagnetic component 400 are respectively provided on opposite sides of the support position 110. The access end 401 of the electromagnetic component 400 is led out from the center position of the electromagnetic component 400.

[0083] It is worth mentioning that the cylinder head body 103 is provided with an intake port 101 and an exhaust port 102. Since the cylinder head body 103 is an axisymmetric figure, the intake port 101 and the exhaust port 102 are also axisymmetric.

[0084] In addition, please see Figure 1As shown, the cylinder head body 103 is provided with two sides of the bottom of the cylinder head body 103. The cylinder head body 103 is provided with the bottom of the cylinder head body 103 and extends upward at an angle. The cylinder head body 103 has an angle with the bottom of the cylinder head body 103. This angle is an acute angle, so as to introduce the air outside the combustion chamber into the intake port 101 or exhaust the gas from the exhaust port 102 to the combustion chamber.

[0085] Furthermore, please see Figure 1 As shown, the valve train 10 also includes a cylinder head cover 500. The cylinder head cover 500 is located on the side of the cylinder head 100 away from the combustion chamber and forms a receiving chamber 501 with the cylinder head 100. The intake assembly 200 and the exhaust assembly 300 are both located in the receiving chamber 501 to protect the intake assembly 200 and the exhaust assembly 300 from damage, ensure normal intake of the intake port 101 and normal exhaust of the exhaust port 102, and thus ensure the combustion efficiency of the combustion chamber.

[0086] It should be noted that the electromagnetic body 404 in the electromagnetic component 400 is located in the receiving chamber 501. The input terminal 401 of the electromagnetic coil 405 is located in the receiving chamber 501, and the other part is led out from the receiving chamber 501. The led-out part can be connected to the power supply outside the combustion chamber to pass current.

[0087] In addition, please see Figure 1 As shown, the receiving chamber 501 has a first opening 510 and a second opening 511, which correspond to the air inlet 101 and the exhaust outlet 102, respectively. When no current is input to the connection terminal 401, the air intake block 201 is located at the first opening 510 and blocks the air inlet 101, and the exhaust block 301 is located at the second opening 511 and blocks the exhaust outlet 102. Furthermore, the opening area of ​​the first opening 510 / second opening 511 is the same as the size of the air intake block 201 / exhaust block 301, that is, the air intake block 201 / exhaust block 301 fits into the first opening 510 / second opening 511 to ensure that gas from outside the combustion chamber can be fully allowed to enter or gas from inside the combustion chamber can be fully allowed to exit only when the air inlet 101 and the exhaust outlet 102 are fully open.

[0088] In this embodiment, both the intake baffle 201 and the exhaust baffle 301 can slide on the surface of the cylinder head body 103, thereby blocking and opening the intake port 101 and the exhaust port 102.

[0089] It should be noted that by placing the intake baffle 201 and the exhaust baffle 301 on the side of the cylinder head 100 away from the combustion chamber, the intake port 101 and the exhaust port 102 can be blocked or opened, and the installation of the intake baffle 201 and the exhaust baffle 301 is also more convenient.

[0090] Please see below. Figure 1 As shown, in order to enable the intake assembly 200 to open or close the intake port 101, the intake assembly 200 also includes a moving rod 610, an elastic element 611, a limiting shell 612, and a limiting block 613 arranged on the moving path of the intake baffle 201. It should be noted that this moving path can be parallel to the surface of the intake assembly 200 on the cylinder head 100; that is, the intake baffle 201, the moving rod 610, the elastic element 611, the limiting shell 612, the limiting block 613, and the first magnetic element 202 are arranged on the surface of the cylinder head body 103.

[0091] The limiting block 613 is fixedly mounted on the surface of the cylinder head body 103 away from the combustion chamber, and the limiting block 613 is provided with a through hole.

[0092] The moving rod 610 is parallel to the surface of the cylinder head body 103. The end of the moving rod 610 away from the first end 402 is fixedly provided with the intake block 201, and the moving rod 610 and the intake block 201 are interference-fitted to ensure a stable fit between the intake block 201 and the moving rod 610. The other end of the moving rod 610 passes through the through hole on the limiting block 613 and extends along the surface of the cylinder head body 103. The other end of the moving rod 610 is provided with a limiting shell 612, an elastic element 611 and a first magnetic element 202. That is, the intake block 201 and the limiting shell 612, the elastic element 611 and the first magnetic element 202 are respectively located on opposite sides of the limiting block 613.

[0093] The elastic element 611 is sleeved on the moving rod 610. The limiting shell 612 includes a first placement position 620 and a second placement position 621 connected to each other. The opening directions of the first placement position 620 and the second placement position 621 are opposite, that is, the first placement position 620 is set towards the side facing the first end 402, and the second placement position 621 is set towards the side facing the air intake block 201. The first placement position 620 is filled with the aforementioned first magnetic element 202. One end of the elastic element 611 abuts against the bottom wall of the second placement position 621, and the other end of the elastic element 611 abuts against the side of the limiting block 613 near the first end 402. The elastic element 611 can be compressed between the second placement position 621 and the limiting block 613, so that the elastic element 611 has a certain elastic restoring force. In addition, the elastic element 611 can also be placed between the second placement position 621 and the limiting block 613 without deformation. The specific design can be made according to different embodiments.

[0094] When current is input to terminal 401 of electromagnetic component 400, please refer to [link / reference]. Figure 3As shown, when the magnetism of the first end 402 is the same as that of the first magnetic element 202 near the first end 402, the first end 402 and the first magnetic element 202 repel each other, which will drive the limiting shell 612 to move away from the first end 402, thereby driving the elastic element 611 to compress between the second placement position 621 and the limiting block 613. Since the limiting block 613 is fixed on the cylinder head body 103, when the elastic element 611 is compressed, the limiting shell 612 will drive the moving rod 610 to move away from the first end 402, that is, the moving rod 610 slides in the through hole; the intake baffle 201 gradually moves from the intake port 101 to the direction away from the first end 402, thereby opening the intake port 101, and the gas outside the combustion chamber enters the combustion chamber through the intake port 101. When the direction of the input current at the access terminal 401 is changed, due to the elastic restoring force of the elastic element 611, the intake block 201 can move more easily to the intake port 101 to block the intake port 101.

[0095] When current is input to terminal 401 of electromagnetic component 400, please refer to [link / reference]. Figure 4 As shown, when the magnetism of the first end 402 is opposite to that of the first magnetic element 202 near the first end 402, the first end 402 and the first magnetic element 202 attract each other. Since the limiting block 613 is fixed on the cylinder head body 103 and the first placement position 620 is open towards the first end 402, it cannot push the limiting shell 612 to move towards the first end 402, and thus will not drive the moving rod 610 to move towards the first end 402. This intake block 201 continues to block the intake port 101, and the gas outside the combustion chamber will not enter the combustion chamber through the intake port 101.

[0096] Understandably, the cylinder head cover 500 has a slot 520 on the inner wall near the cylinder head body 103. The end of the limiting block 613 away from the cylinder head body 103 is inserted into the slot 520. The slot 520 stably fixes the limiting block 613 in the receiving chamber 501, which can further limit the position of the limiting block 613 in the receiving chamber 501 and prevent the limiting block 613 from sliding at will.

[0097] In addition, this elastic element 611 can be made of spring, rubber or other elastic materials.

[0098] It should be noted that the surface of the first magnetic element 202 can be flush with the surface of the first placement position 620, that is, the length of the first magnetic element 202 is the same as the depth of the first placement position 620. Of course, the first magnetic element 202 can also be completely located within the first placement position 620, that is, the length of the first magnetic element 202 is less than the depth of the first placement position 620.

[0099] In some embodiments, the first placement position 620 and the second placement position 621 can be arranged sequentially along the axial direction of the moving rod 610, that is, the first placement position 620 is located on the side of the moving rod 610 close to the first end 402, and the second placement position 621 is located on the side of the first placement position 620 away from the first end 402.

[0100] In the embodiments of this application, see Figure 1 As shown, the first placement position 620 and the second placement position 621 can also be arranged sequentially in the radial direction of the moving rod 610, and the opening of the first placement position 620 is flush with the bottom wall of the second placement position 621, and the opening of the second placement position 621 is flush with the bottom wall of the first placement position 620.

[0101] It is worth mentioning that the bottom wall of the second placement position 621 is provided with an opening, through which the moving rod 610 passes, and the moving rod 610 is interference-fitted with the opening, that is, the moving rod 610 can move together with the limiting shell 612.

[0102] Please see Figure 1 As shown, the support part 104 is provided with a limiting groove 112. The end of the moving rod 610 away from the air intake block 201 is inserted into this limiting groove 112 to limit and fix the moving rod 610. When no current is input to the connection end 401, the distance between the moving rod 610 and the top of the limiting groove 112 is greater than the area of ​​the air intake 101 to prevent the moving rod 610 from falling off the limiting groove 112 and to ensure the stability of the moving rod 610. In addition, the moving rod 610 is at a certain distance from the bottom of the limiting groove 112 to ensure that there is a certain amount of accommodating space and to ensure the integrity of the moving rod 610.

[0103] Understandably, see Figures 1 to 2 As shown, the structure of the exhaust assembly 300 is the same as that of the intake assembly 200, that is, the exhaust assembly 300 includes any of the structures in the intake assembly 200, which is the same as described above, and will not be repeated here.

[0104] It should be noted that when the intake assembly 200 is intake, the exhaust baffle 301 in the exhaust assembly 300 does not move; when the exhaust assembly 300 is exhausting, the intake baffle 201 in the intake assembly 200 does not move.

[0105] For example, during air intake: See Figure 3As shown, the input terminal 401 is connected to a positive current. The magnetic poles of the first terminal 402 and the first magnetic component 202 facing the first terminal 402 are both north poles (N poles). The two repel each other. The first terminal 402 pushes the first magnetic component 202 to move away from the first terminal 402, which drives the limiting shell 612 and the moving rod 610 of the air intake assembly 200 to move away from the first terminal 402. This causes the air intake baffle 201 to gradually slide away from the first terminal 402, and the air intake port 101 is gradually opened. The gas outside the combustion chamber is introduced into the air intake port 101 through the guide part 120, and the gas enters the combustion chamber. The second end 403 is the south pole (S pole), and the magnetic pole of the second magnetic element 302 facing the second end 403 is the north pole (N pole). The two attract each other. Since the first placement position 620 of the limiting shell 612 in the exhaust assembly 300 is open towards the second end 403, and the limiting block 613 of the exhaust assembly 300 is fixed to the cylinder head body 103 via the slot 520, the attraction between the second end 403 and the second magnetic element 302 will not cause the limiting shell 612 of the exhaust assembly 300 to move towards the second end 403. Consequently, the moving rod 610 in the exhaust assembly 300 will not move towards the second end 403, so that the exhaust baffle 301 is stably sealed at the exhaust port 102, and the gas in the combustion chamber will not be discharged from the exhaust port 102. That is, the combustion chamber only receives air.

[0106] During exhaust, reverse current is applied to terminal 401, see [reference]. Figure 4As shown, the magnetic poles of the second end 403 and the second magnetic component 302 facing the second end 403 are both north poles (N poles), and they repel each other. The second end 403 pushes the second magnetic component 302 to move away from the second end 403, which in turn drives the limiting shell 612 and the moving rod 610 of the exhaust assembly 300 to move away from the second end 403. This, in turn, causes the exhaust baffle 301 to gradually slide away from the second end 403, and the exhaust port 102 is gradually opened. The gas in the combustion chamber is led out to the outside of the combustion chamber through the exhaust port 102 and the guide part 120, and the combustion chamber exhausts gas. The first end 402 is the south pole (S pole), and the first magnetic element 202 facing the magnetic pole of the first end 402 is the north pole (N pole). The two attract each other. Since the first placement position 620 of the limiting shell 612 in the intake assembly 200 is open towards the first end 402, and the limiting block 613 of the intake assembly 200 is fixed by the slot 520 and the cylinder head body 103, it is ensured that the mutual attraction between the first end 402 and the first magnetic element 202 will not cause the limiting shell 612 of the intake assembly 200 to move towards the first end 402. Consequently, it will not cause the moving rod 610 in the intake assembly 200 to move towards the first end 402. This allows the intake baffle 201 to be stably sealed at the intake port 101, and the gas outside the combustion chamber will not enter the combustion chamber from the intake port 101; that is, the combustion chamber only exhausts gas.

[0107] When no current is input to the access terminal 401, see [link / reference]. Figure 5 As shown, the first end 402 and the second end 403 are non-magnetic, ensuring that the first magnetic component 202 and the second magnetic component 302 do not repel or attract each other. This guarantees that the moving rod 610 of the intake assembly 200 and the moving rod 610 of the exhaust assembly 300 will not move, thereby ensuring that the intake baffle 201 is blocked at the intake port 101 and the exhaust baffle 301 is blocked at the exhaust port 102. That is, the combustion chamber neither intakes nor exhausts air, and other compression or isentropic work states occur within the combustion chamber.

[0108] In addition, see Figure 1 As shown, the air distribution system 10 also includes sensors, a controller 701, and a current controller 702. The air distribution system 10 includes multiple sensors, each with a signal output terminal, which is electrically connected to the controller 701. The sensors transmit the detected signals to the controller 701, which can obtain an output control signal based on the detection signals transmitted from the multiple sensors. This output control signal includes the optimal opening degree of the intake port 101 and the exhaust port 102.

[0109] The current controller 702 includes a signal input port 720, a current input port 721, and a transmission port 722. The signal input port 720 is electrically connected to the output port of the controller 701 to transmit the output control signal output by the controller 701 based on the detection signal to the current controller 702. The current controller 702 obtains the current direction and magnitude signals based on the output control signal. The current input port 721 transmits current to the current sensor based on the current direction and magnitude signals. Since the transmission port 722 is electrically connected to the access terminal 401 of the electromagnetic component 400, the transmission port 722 transmits current to the access terminal 401. The electromagnetic component 400 can determine the magnetism and magnetic force of its first terminal 402 and second terminal 403 based on the current direction and magnitude. By controlling the magnetism and magnetic force of the first terminal 402 and second terminal 403, the opening degree of its air inlet 101 / exhaust port 102 can be determined.

[0110] In other words, the solution of this application can calculate the optimal opening degree of the intake port 101 and exhaust port 102 by receiving detection signals from various sensors during engine operation, and then control the current controller 702 to control the magnitude and direction of the current input to the electromagnetic component 400, so that the combustion chamber can always be kept at the optimal intake and exhaust opening degree, which can greatly improve fuel efficiency.

[0111] Furthermore, this sensor, controller 701, and current controller 702 ensure that the air inlet 101 and the exhaust outlet 102 can be opened and closed at any time.

[0112] This application's solution replaces the complex mechanical valve train structure with this electromagnetic valve train system 10, reducing mechanical transmission components and saving space occupied by the valve train structure. Furthermore, the electromagnetic valve train system 10 also reduces noise generated by the mechanical transmission structure, exhibiting excellent noise, vibration, and harshness performance. In addition, through sensors, controller 701, and current controller 702, the opening and closing of the engine at any crankshaft angle can be precisely controlled, ensuring continuous high-efficiency combustion and higher fuel efficiency. It can also control the opening and closing of the intake port 101 or exhaust port 102 at any time, maintaining the engine at its optimal intake and exhaust opening.

[0113] It is worth mentioning that the electromagnetic gas distribution system 10 in this application only requires one electromagnetic body 404 to complete the opening and closing of the air inlet 101 and the exhaust port 102. The number of structural components is reduced, the cost is reduced accordingly, and the control is reliable.

[0114] Furthermore, since the intake baffle 201 and the exhaust baffle 301 are located on the surface of the cylinder head body 103, assembly is simpler and more convenient.

[0115] Example 2

[0116] Embodiment 2 of this application provides a vehicle, which includes an engine and a valve train 10 as described in Embodiment 1. The valve train 10 has the relevant structure described in Embodiment 1, which will not be described in detail again.

[0117] This valve train system 10 saves space occupied by the valve train structure. The electromagnetic valve train system 10 also reduces noise generated by the mechanical transmission structure, offering excellent noise, vibration, and harshness performance. Furthermore, through sensors, controller 701, and current controller 702, the engine can be precisely controlled to open and close at any crankshaft angle, ensuring continuous high-efficiency combustion and higher fuel efficiency. It can also control the opening and closing of the intake port 101 or exhaust port 102 at any time, maintaining optimal intake and exhaust openings. Notably, the electromagnetic valve train system 10 in this application requires only one electromagnetic body 404 to complete the opening and closing of the intake port 101 and exhaust port 102, reducing structural components, lowering costs, and ensuring reliable control. Moreover, since the intake baffle 201 and exhaust baffle 301 are located on the surface of the cylinder head body 103, assembly is simpler and more convenient.
