[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0050] According to the first aspect of the present application, please refer to Figure 1 The one-way valve seat 1 provided by the present disclosure is provided with a first one-way valve passage 3 and a one-way valve through hole 4, and the one-way valve seat 1 has at least one sealing surface 2, which is adapted to abut against the first one-way valve valve plate 5, so that the first one-way valve valve plate 5 is adapted to allow fluid to flow from the one-way valve through hole 4 to the first one-way valve passage 3 in one direction; wherein the width of each sealing surface 2 is less than or equal to 0.4 mm.

[0051] It can be understood that when the width of the sealing surface 2 is greater than 0.4 mm, the sealing surface 2 has a larger surface adhesion when it is attached, so that it is difficult for the first one-way valve valve plate 5 to open.

[0052] In the present embodiment, the width of the sealing surface 2 of the one-way valve seat 1 is set to be less than or equal to 0.4 mm, so that the instantaneous impact force when the fluid flows at the sealing surface 2 forms a smaller impact noise, which can meet the noise noise requirement.

[0053] In an embodiment, the width of the sealing surface 2 is greater than or equal to 0.05 mm.

[0054] It can be understood that when the width of the sealing surface 2 is less than 0.05 mm, the sealing effect is poor, and the difficulty of the preparation process is increased, which is not convenient for mass production.

[0055] It can be understood that when the width of the sealing surface 2 is less than 0.4 mm, the tension of the fluid between the first one-way valve flap 5 and the sealing surface 2 is small, the instantaneous acceleration of the fluid flow is small, and the impact noise formed by the impact force of the fluid flow is small, thereby meeting the noise requirement.

[0056] In an embodiment, the sealing surface 2 is a flat surface.

[0057] It can be understood that the sealing surface 2 is a flat surface, which can enhance the sealing effect between the sealing surface 2 and the first one-way valve flap 5.

[0058] In an embodiment, the flatness of the sealing surface 2 is less than or equal to 0.005 mm.

[0059] The flatness of the sealing surface 2 can be any one of 0.001 mm, 0.003 mm, and 0.005 mm.

[0060] It can be understood that the smaller the flatness of the sealing surface 2, the smoother the surface of the sealing surface 2, and the better the sealing effect between the sealing surface 2 and the first one-way valve flap 5.

[0061] In an embodiment, the one-way valve seat 1 has two sealing surfaces 2, and the one-way valve through hole 4 is arranged between the two sealing surfaces 2. The distance between the two sealing surfaces 2 ranges from 0.5 mm to 5 mm.

[0062] The distance between the two sealing surfaces 2 can be any one of 0.5 mm, 2 mm, 3 mm, and 5 mm.

[0063] It can be understood that when the distance between the two sealing surfaces 2 is less than 0.5 mm, the size is too small, which increases the difficulty of preparation and is not conducive to mass production; when the distance between the two sealing surfaces 2 is greater than 5 mm, the distance between the two sealing surfaces 2 is too large, which causes the cross-sectional area of the first one-way valve passage 3 to be small, thereby affecting the flow of the first one-way valve passage 3.

[0064] In an embodiment, please refer to Figure 1 The one-way valve seat 1 includes a body part 21 and a sealing part 22 connected to the body part 21. The body part 21 is provided with the first one-way valve passage 3, and the body part 21 and the sealing part 22 each have a sealing surface 2.

[0065] The sealing part 22 can be arranged around the outer periphery of the body part 21.

[0066] The shape of the sealing surface 2 can be annular.

[0067] It can be understood that the body part 21 and the sealing part 22 each have a sealing surface 2, and the two sealing surfaces 2 are arranged around and spaced apart, thereby sealing the position between the two sealing surfaces 2.

[0068] In an embodiment, referring to Figure 1 , the one-way valve seat 1 further comprises a connecting portion 23 connected between the body portion 21 and the sealing portion 22, and the connecting portion 23 is provided with the one-way valve through hole 4.

[0069] It can be understood that the one-way valve through hole 4 is arranged in the connecting portion 23 between the body portion 21 and the sealing portion 22, and the two sealing surfaces 2 are used to seal the one-way valve through hole 4 located between the two sealing surfaces 2 to improve the sealing effect.

[0070] In an embodiment, referring to Figure 1 , the connecting portion 23 is provided with a groove 24, and the one-way valve through hole 4 is arranged at the bottom wall of the groove 24.

[0071] Among them, the groove 24 is a recessed position between the two sealing surfaces 2.

[0072] It can be understood that the one-way valve through hole 4 is arranged in the groove 24, and the first one-way valve valve plate 5 abuts against the sealing surface 2 to seal the groove 24 and the one-way valve through hole 4 located in the groove 24.

[0073] In an embodiment, the flexibility of the one-way valve seat 1 is adapted to be greater than the flexibility of the first one-way valve valve plate 5.

[0074] It can be understood that the greater the flexibility of the one-way valve seat 1, the smaller the loss of the grinding tool for manufacturing the one-way valve seat 1, and the more the number of good products corresponding to the one-way valve seat 1 manufactured by the same grinding tool, thereby reducing the cost.

[0075] According to the second aspect of the present application, referring to Figure 1 and Figure 2 , the one-way valve 25 provided comprises the one-way valve seat 1 and the first one-way valve valve plate 5 according to any one of the above embodiments.

[0076] It can be understood that the sealing surface 2 of the one-way valve seat 1 and the first one-way valve valve plate 5 abut against each other to achieve the effect of the one-way valve 25 allowing fluid to pass through in one direction.

[0077] In an embodiment, referring to Figure 2 , further comprising a one-way valve body 6 and a second one-way valve 25 valve plate, the one-way valve body 6 is provided with a second one-way valve passage 8, and the second one-way valve 25 valve plate is installed on the one-way valve body 6 to adapt to allow fluid to flow from the first one-way valve passage 3 to the second one-way valve passage 8 in one direction.

[0078] Among them, the second one-way valve 25 valve plate is located on the side of the first one-way valve valve plate 5 close to the first valve 12.

[0079] It can be understood that the second one-way valve channel 8 is used for fluid to flow from the first one-way valve channel 3 to the second one-way valve channel 8 in a one-way manner, avoiding the backflow of fluid from the second one-way valve channel 8 to the first one-way valve channel 3.

[0080] In an embodiment, referring to Figure 2 , the one-way valve further comprises a one-way valve body 6 connected to the one-way valve seat 1 and an elastic member 9 abutting between the first one-way valve disc 5 and the one-way valve body 6.

[0081] In the embodiment, the elastic member 9 is located between the first one-way valve disc 5 and the one-way valve body 6 and is in a compressed state, so that the first one-way valve disc 5 is pressed by the elastic member 9 on the sealing surface 2 and is pushed open toward the side of the one-way valve body 6, at least overcoming the elastic force of the elastic member 9.

[0082] It can be understood that the elastic member 9 makes the first one-way valve disc 5 abut more closely on the sealing surface 2, so as to better achieve the one-way flow effect of the one-way valve 25.

[0083] According to a third aspect of the present application, referring to Figure 2 , a valve assembly 10 is provided, comprising the one-way valve seat 1 according to any one of the above embodiments or the one-way valve 25 according to any one of the above embodiments.

[0084] In the embodiment, the valve assembly 10 can comprise at least one of the one-way valve 25, an overflow valve, a solenoid valve, and a pilot valve 34.

[0085] In an embodiment, referring to Figure 2 , the valve assembly 10 further comprises a control assembly 11 and a first valve 12; when the control assembly 11 is in a first state, the first valve 12 forms a first channel 26, and fluid is adapted to flow through the first one-way valve channel 3 and the first channel 26 in sequence; when the control assembly 11 is in a second state, the first valve 12 forms a second channel 27, and fluid is adapted to flow through the first one-way valve channel 3 and the second channel 27 in sequence; the first channel 26 and the second channel 27 are different.

[0086] In the embodiment, the control assembly 11 can be a solenoid valve.

[0087] It can be understood that in the first state, fluid flows through the first one-way valve channel 3 and the first channel 26 in sequence, and in the second state, fluid flows through the first one-way valve channel 3 and the second channel 27 in sequence, so that in different working states, fluid passes through different paths, so that the shock absorber 18 exhibits different states to adapt to different road conditions.

[0088] In an embodiment, the first state is a power-off state, and the second state is a power-on state.

[0089] It can be understood that the first state is a power-off state, at this time the electromagnetic valve has a current of 0, at this time the opening degree corresponding to the valve port of the first valve 12 is larger, so that the flow resistance of the fluid is small, and it is suitable for flat road conditions.

[0090] It can be understood that the second state is a power-on state, at this time the electromagnetic valve has a current value, the larger the current value, the smaller the opening degree corresponding to the valve port of the first valve 12, so that the flow resistance of the fluid is larger, and it is suitable for pit road conditions.

[0091] In an embodiment, the pressure of the fluid when the control assembly 11 is in the second state is greater than the pressure of the fluid when the control assembly 11 is in the first state.

[0092] It can be understood that when the second state, the electromagnetic valve is powered on, so that the first valve body 30 of the first valve 12 and the first valve seat 31 of the first valve 12 are more closely abutted, and the fluid needs a larger pressure to open the first valve body 30 of the first valve 12 so that the valve port of the first valve 12 has an opening degree; and in the first state, the electromagnetic valve is not powered on, at this time the first valve body 30 of the first valve 12 is only abutted between the first valve seat 31 of the first valve 12 through another spring located between the first valve body 30 of the first valve 12 and the guide sleeve 32 of the first valve 12, at this time the fluid only needs a smaller pressure to have an opening degree.

[0093] In an embodiment, referring to Figure 2 , the control assembly 11 includes a push rod 13; wherein the pushing force of the push rod 13 on the first valve 12 when the control assembly 11 is in the second state is greater than the pushing force of the push rod 13 on the first valve 12 when the control assembly 11 is in the first state.

[0094] It can be understood that the push rod 13 is used to press the first valve body 30 of the first valve 12 against the first valve seat 31 of the first valve 12 under the control of the electromagnetic valve, when the electromagnetic valve is powered on, the pushing force of the push rod 13 on the valve body of the first valve 12 towards the side of the one-way valve 25 is enhanced, so that the valve port of the first valve 12 is more difficult to open.

[0095] In an embodiment, when the control assembly 11 is in the second state, the push rod 13 is adapted to be pushed away from the first valve 12 by the fluid, so that the first valve 12 forms the second channel 27.

[0096] It can be understood that in the second state, the electromagnetic valve is powered on, the pushing force of the push rod 13 on the valve body of the first valve 12 towards the side of the one-way valve 25 is enhanced, the valve port of the first valve 12 is more difficult to open, so that the first valve 12 forms the second channel 27 for the fluid to pass through.

[0097] In one embodiment, when the control assembly 11 is in the second state, the second passage 27 comprises the first sub-passage 28 in a first time period, and the second passage 27 comprises the first sub-passage 28 and the second sub-passage 29 in a second time period after the first time period.

[0098] It can be understood that, in the first time period, the pressure of the fluid is not enough to open the second sub-passage 29, and the fluid only passes through the first sub-passage 28; when the pressure of the fluid reaches a degree to open the second sub-passage 29, the first sub-passage 28 and the second sub-passage 29 are opened at the same time, and the fluid passes through the first sub-passage 28 and the second sub-passage 29 at the same time.

[0099] In one embodiment, referring to Figure 4 and Figure 5 , the second sub-passage 29 is the same as the first passage 26.

[0100] It can be understood that, the second sub-passage 29 and the first passage 26 are both valve ports formed at the abutting position of the first valve body 30 of the first valve 12 and the first valve seat 31 of the first valve 12, and the valve ports are opened when the first valve body 30 of the first valve 12 and the first valve seat 31 of the first valve 12 move away from each other, wherein, in the first state, the valve ports are opened to form the first passage 26; in the second state, the valve ports are opened to form the second sub-passage 29.

[0101] In one embodiment, the pressure of the fluid flowing through the second passage 27 in the first time period is less than the pressure of the fluid flowing through the second passage 27 in the second time period.

[0102] It can be understood that, the pressure of the fluid in the second time period is greater than the pressure of the fluid in the first time period, so that the pressure of the fluid in the second time period is enough to open the second sub-passage 29.

[0103] In one embodiment, the first valve 12 is a relief valve.

[0104] It can be understood that, the relief valve adjusts the resistance of the fluid flow by adjusting the opening degree of the valve port of the relief valve, and the larger the opening degree of the valve port, the smaller the resistance of the fluid flow, and the smaller the opening degree of the valve port, the greater the resistance of the fluid flow.

[0105] According to a fourth aspect of the present application, referring to Figure 3 , Figure 4 , Figure 5 , a damping controller 33 is provided, comprising the one-way valve seat 1 according to any one of the above embodiments, or the one-way valve 25 according to any one of the above embodiments, or the valve assembly 10 according to any one of the above embodiments.

[0106] In one embodiment, referring to Figure 4 and Figure 5, the valve assembly 10 further comprises a control assembly 11 and a first valve 12; wherein when the control assembly 11 is in a first state, the first valve 12 forms a first passage 26, and the fluid is adapted to flow through the first one-way valve passage 3 and the first passage 26 in turn; when the control assembly 11 is in a second state, the first valve 12 forms a second passage 27, and the fluid is adapted to flow through the first one-way valve passage 3 and the second passage 27 in turn; the first passage 26 and the second passage 27 are different.

[0107] Wherein, in the first state, the fluid passes through the first one-way valve passage 3 and the first passage 26; in the second state, the fluid passes through the first one-way valve passage 3 and the second passage 27, so as to realize that the damping controller 33 can have different fluid flow resistances in different road conditions, thereby having better damping effect in different road conditions.

[0108] In an embodiment, please refer to Figure 3 Further comprising a housing 14 and two valve assemblies 10, the housing 14 has two first connecting cavities 15, a second connecting cavity 16 and a third connecting cavity 17, and the two valve assemblies 10 are respectively installed in the two first connecting cavities 15; wherein the second connecting cavity 16 is connected to the third connecting cavity 17 through the two valve assemblies 10.

[0109] It can be understood that the communication relationship between the second connecting cavity 16 and the third connecting cavity 17 is controlled by the valve assembly 10, so as to flow the fluid from the second connecting cavity 16 to the third connecting cavity 17 or from the third connecting cavity 17 to the second connecting cavity 16 according to the demand.

[0110] In an embodiment, please refer to Figure 4 When the two control assemblies 11 are in the first state, the second connecting cavity 16 is connected to the third connecting cavity 17 through the first one-way valve passage 3 and the first passage 26 of one of the valve assemblies 10, and the one-way valve through hole 4 and the first one-way valve passage 3 of the other valve assembly 10.
