[0084] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0085] Reference Figures 11 to 22 As shown, for the convenience of introduction, the upper, lower, left and right directions are adopted in the corresponding drawings to facilitate the introduction of the relative position relationship between the various parts in the present application, which should not be understood as a limitation on the absolute position.
[0086] Moreover, in the present application, the axial direction of the center axis corresponds to the left and right direction, and the radial direction of the center axis corresponds to the up and down direction; similarly, the axial direction of the center axis corresponds to the left and right direction only for the convenience of introducing the specific embodiments of the present application. There is no absolute corresponding relationship between the axial direction of the center axis and the left and right direction. Similarly, there is no absolute corresponding relationship between the radial direction of the center axis and the up and down direction.
[0087] In order to achieve the above object, according to the first aspect of the present application, reference is made to Figure 1 , a tire pressure regulating method is provided, comprising:
[0088] S210: According to the current air pressure of the tire, adjusting the inflation pressure of the tire so that the valve 100 of the tire has an opening adapted to the inflation pressure;
[0089] The inflation pressure includes a transition pressure, which enables the tire valve 100 to maintain a transition opening greater than the minimum opening of the valve and less than the maximum opening of the tire valve 100.
[0090] Through the above technical solution, the use of transitional air pressure can keep the tire valve 100 at a transitional opening, thereby adjusting the tire pressure accordingly, actively and effectively managing the tire pressure, and further reducing the operator's involvement in tire pressure adjustment.
[0091] It should be noted that the use of inflation pressure allows the valve to have an opening that matches the inflation pressure. The inflation pressure is used not only in the process of inflating the tire, but also in the process of deflating the tire. At least it is sufficient to allow the valve to have a corresponding opening.
[0092] In some embodiments, reference Figure 4 , step S210 includes:
[0093] Step S211: The inflation pressure reaches a transition pressure to trigger the tire valve 100 to be in a transition locking state to maintain a transition opening.
[0094] By making the inflation pressure reach the transition pressure to trigger the tire valve 100 to be in the transition locking state of maintaining the transition opening, the method of enabling the tire valve 100 to maintain the transition locking state of the transition opening is simple.
[0095] In some embodiments, reference Figure 2 , the adjustment method also includes:
[0096] Step S220: When the tire valve 100 is at a transition opening, stop inflating the tire or deflate the tire.
[0097] Among them, when the tire valve 100 is at a transition opening, the tire is stopped from being inflated. At this time, stopping the tire from being inflated can perform a pressure-maintaining action for the tire to avoid over-inflation of the tire. Alternatively, when the tire valve 100 is at a transition opening, the tire is deflated. The operation is convenient, and the method for adjusting the tire air pressure is simple and easy to operate.
[0098] In some embodiments, reference Figure 2 , the adjustment method also includes:
[0099] Step S230: when the valve 100 of the tire is in a transitional opening and the tire reaches a first target tire pressure, releasing the transitional locking state of the valve with a first unlocking air pressure greater than the transitional air pressure.
[0100] Step S230, when the tire valve 100 is in a transitional opening and the tire reaches a first target tire pressure, the transitional locking state of the valve is released by a first unlocking air pressure greater than the transitional air pressure, and the transitional locking of the valve is released by air pressure, thereby further improving the simplicity of the air pressure regulation method.
[0101] In some embodiments, reference Figure 4 , step S210 further includes:
[0102] Step S212: The inflation pressure reaches the full-open pressure to trigger the tire valve 100 to be in a fully-open locked state with a maximum opening.
[0103] Through step S212, the valve 100 of the tire is kept in a fully open and locked state with a maximum opening. In the fully open and locked state, the air pressure of the tire can be adjusted, for example, inflated.
[0104] In some embodiments, reference Figure 3 , the adjustment method also includes:
[0105] Step S240: When the valve 100 of the tire is at the maximum opening, the tire is inflated with an inflation pressure greater than the transition pressure.
[0106] Through step S240, when the tire valve 100 is at the maximum opening, the tire is inflated with an inflation pressure greater than the transition pressure. At this time, the tire valve 100 will continue to maintain the maximum opening and will not switch to the transition opening. The tire can be inflated with an inflation pressure greater than the transition pressure at the maximum opening, and the inflation efficiency is high.
[0107] In some embodiments, the adjusting method further comprises:
[0108] Step S250: when the valve 100 of the tire is at the maximum opening and the tire reaches the second target tire pressure, the fully open locking state of the valve is released with a second unlocking air pressure that is less than the fully open air pressure.
[0109] When the tire reaches the second target tire pressure, the fully open locked state of the valve is released by a second unlocking air pressure that is less than the fully open air pressure. The fully open locked state of the valve can be released by the second unlocking air pressure, so that the valve can be released from the fully open locked state and perform other corresponding operations, such as making the valve opening at the minimum opening, or making the valve opening at the transition opening.
[0110] It should be noted that the fully open locking state of the valve can be unlocked by adjusting the inflation pressure to a second unlocking pressure that is less than the fully open pressure, which is easy to operate.
[0111] Among them, during the process of inflating and deflating the tire, the first target tire pressure is less than the second target tire pressure, and the second target tire pressure is the final tire pressure of the tire. Using the first target tire pressure as the intermediate tire pressure between the initial tire pressure and the final tire pressure of the tire can maintain the tire pressure, that is, the gas re-inflated into the tire will not affect the tire's operating tire pressure and the difference between it and the target is too large, thereby avoiding over-inflation or under-deflation.
[0112] In some embodiments, reference Figure 4 , step S210 further includes:
[0113] Step S215: reducing the inflation pressure to the fully closed pressure to trigger the tire valve 100 to be in the fully closed state.
[0114] By reducing the inflation pressure to the fully closed pressure, the valve 100 of the tire can be set to be in a fully closed state. At this time, the valve 100 of the tire is at the minimum opening, and the valve is closed.
[0115] In some embodiments, reference Figure 4 , step S210 further includes:
[0116] Step S213: adjusting the inflation pressure from the full-open pressure to the transition pressure, so that the valve 100 of the tire switches from the maximum opening to the transition opening.
[0117] By adjusting the inflation pressure from the full-open pressure to the transition pressure, the tire valve 100 can be switched from the maximum opening to the transition opening, completing the switching of the tire valve 100 from the full-open locked state to the transition locked state, that is, the full-open unlocked state of the tire valve 100 can be released. When the tire valve 100 has a transition opening to put the tire valve 100 in the transition locked state, the pressure of the tire that needs to be inflated or deflated can be maintained, or the tire that needs to be deflated can be continuously deflated, to avoid over-inflation or inadequate deflation, which may fail to meet the requirements of the tire's use environment, thereby achieving the effect of stable inflation or deflation of the tire.
[0118] In some embodiments, reference Figure 4 , after step S213, the following steps are also included:
[0119] Step S214: Regulate the inflation pressure from the transition pressure to the fully open pressure and then to the fully closed pressure.
[0120] By adjusting the inflation pressure from the transition pressure to the fully open pressure and then to the fully closed pressure, the tire valve 100 has an opening value switch, thereby avoiding the unstable inflation and deflation effect caused by the tire valve 100 only switching between the maximum opening and the minimum opening when inflating the tire. The inflation and deflation of the tire can be adjusted at the transition opening, avoiding the situation where the air pressure is not adjusted properly.
[0121] It should be noted that step S214 is performed after step S213, and step S215 is performed after step S214. By adjusting the inflation pressure to realize the opening operation of the tire valve, the inflation and deflation operation of the tire is completed without the operator's deep involvement in the valve opening adjustment process.
[0122] In some embodiments, reference Figure 5 , the adjustment method also includes:
[0123] Step S260: according to the inflation pressure, the ambient air pressure of the central air path is reduced to the ambient target air pressure.
[0124] By lowering the ambient air pressure of the central air path to the ambient target air pressure, the air pressure of the entire air path can be adjusted, thereby completing the regulation of the tire air pressure.
[0125] For example, during the process of inflating the tire, the inflation pressure is first increased to the full-open pressure so that the opening of the tire valve 100 is maintained at the maximum opening, and the tire is inflated at the full-open pressure at the maximum opening, and the full-open pressure is greater than the transition pressure. After inflating to the preset target tire pressure, the opening of the tire valve 100 is switched to the transition opening at the inflation pressure less than the full-open pressure. At the transition opening, the air source is cut off, the inflation pressure is reduced, and the tire valve 100 is maintained at the transition opening. At this time, the air pressure inside the tire will decrease. When the tire pressure decreases to the first target pressure, the tire will continue to be inflated with an inflation pressure greater than the transition pressure, for example, with a fully open pressure, so that the opening of the tire valve 100 is maintained at the maximum opening. After inflating to the second target pressure, the inflation pressure is gradually reduced so that the opening of the tire valve 100 can be switched to the minimum opening. The tire inflation operation is completed by re-detecting the ambient pressure of the central air circuit to the ambient target pressure.
[0126] Exemplarily, during the process of deflating the tire, the inflation pressure is first used to maintain the opening of the tire valve 100 at the maximum opening, and then the inflation pressure less than the fully open pressure is used to switch the opening of the tire valve 100 to a transitional opening. At the transitional opening, the air source is cut off, the inflation pressure is reduced, and the gas in the tire is released from the tire. After the air pressure in the tire drops to the first target tire pressure, the tire is continued to be inflated with an inflation pressure greater than the transition pressure, for example, with a fully open pressure, the opening of the tire valve 100 is maintained at the maximum opening. After inflating to the second target tire pressure, the inflation pressure is gradually reduced so that the opening of the tire valve 100 can be switched to the minimum opening. The tire deflation operation is completed by re-detecting the ambient air pressure of the central air circuit to the ambient target pressure.
[0127] The second target tire pressure can be set to be slightly larger than the actual required tire pressure during actual operation, so that when the tire valve 100 switches from the maximum opening to the minimum opening, the gas in the tire can be stabilized at the required pressure value after being partially released without too much deviation.
[0128] According to a second aspect of the present application, there is provided an inflation control method, using a central air path for inflating and deflation of a tire to inflate an external object, referring to Figure 6 ,include:
[0129] Step 310: making the inflation pressure of the inflated object reach the inflation target pressure;
[0130] Wherein, making the inflation pressure of the inflated object reach the inflation target pressure includes:
[0131] The valve of the filled object is kept at a preset opening according to the ambient air pressure of the central air circuit.
[0132] By keeping the valve of the object to be filled at a preset opening according to the ambient air pressure of the central air circuit, the external object to be filled can be inflated, and whether the external object to be filled has been fully inflated can be confirmed according to the ambient air pressure of the central air circuit.
[0133] In some embodiments, the inflation control method further comprises:
[0134] Step 320: When the valve of the object to be filled is at a preset opening, the object to be filled is inflated so that the inflation pressure of the object to be filled reaches the inflation target pressure.
[0135] In some embodiments, reference Figure 6 , the inflation control method further includes:
[0136] Step 330: When the inflation pressure of the object reaches the inflation target pressure and the valve of the object is at a preset opening, trigger the valve of the object to be filled to close.
[0137] In some embodiments, the tire pressure regulating method and the inflation control method of the inflated object described in the first aspect of the present application are implemented by an air pressure control system 10 .
[0138] refer to Fig.23 , the air pressure control system 10 includes: an air pressure monitoring module.
[0139] The air pressure monitoring module is used to obtain the current air pressure of the tire and adjust the inflation pressure of the tire so that the valve of the tire has an opening that matches the inflation pressure.
[0140] In some embodiments, the air pressure control system 10 may further include:
[0141] The air pressure control module is used to control the opening of the valve of the tire when the air pressure of the tire reaches a preset threshold, and / or to control the opening of the valve of the inflated object when the air pressure of the inflated object reaches a preset threshold.
[0142] By setting up an air pressure control system 10 to implement a tire pressure adjustment method and an inflation control method for an inflated object, the inflation of the tire and the inflation of the inflated object can be integrated to control the inflation of the tire and the inflated object, thereby improving ease of use, simplifying the operating process, and achieving a higher level of automation, ensuring that the tire pressure and the inflation of the inflated object meet the expected requirements.
[0143] The air pressure control system 10 in the present application only inflates or deflates the tire or inflates the object at the same time, and the inflation and deflation of the tire and the inflation of the object are configured to be performed at different times in terms of operation.
[0144] According to a third aspect of the present application, there is provided an air pressure control system 10, referring to Fig.23 , including: air pressure monitoring module and air pressure control module.
[0145] The air pressure monitoring module is used to obtain the current air pressure of the tire and adjust the inflation pressure of the tire so that the valve of the tire has an opening that matches the inflation pressure.
[0146] The air pressure control module is used to control the opening of the valve of the tire when the air pressure of the tire reaches a preset threshold, and can also be used to control the opening of the valve of the inflated object when the air pressure of the inflated object reaches a preset threshold.
[0147] It should be noted that the air pressure monitoring module and the air pressure control module included in the air pressure control system 10 of the present application may be an air pressure monitoring module and an air pressure control module in a vehicle controller.
[0148] Exemplarily, the vehicle controller may be a vehicle domain controller or a central controller of the vehicle.
[0149] In the technical solution of the present application, the vehicle domain controller refers to a domain controller (DCU, Domain Controller Unit), and the vehicle controller refers to an electronic controller (ECU, Electronic Control Unit).
[0150] The vehicle domain controller is used to implement functional control based on "domains", that is, the vehicle electronic system is decomposed into several functional blocks according to the function. The domain controller takes the lead in building the system architecture inside different functional blocks, and uses multi-core CPU / GPU chips with stronger processing power to relatively centrally control each domain. Based on a simple understanding, DCU can be understood as a central processing unit that implements a program.
[0151] As an optional solution, the vehicle domain controller can be divided into: power domain, chassis domain, cockpit domain, assisted driving domain, body domain, etc. according to specific control functions.
[0152] As an optional solution, the vehicle domain controller can also be divided into the following types according to the parts of the vehicle that are controlled: front domain, rear domain, left domain, and right domain.
[0153] At least one air pressure monitoring module and one air pressure control module may be integrated in a vehicle domain controller. The air pressure monitoring module and the air pressure control module of the present application may be a virtual function module composed of a physical circuit of the vehicle domain controller and an executable program stored therein.
[0154] In the technical solution of the present application, the vehicle controller of the present application may also refer to an electronic controller (ECU, Electronic Control Unit).
[0155] Of course, the air pressure monitoring module of the present application can also be constructed as a tire pressure detection sensor, and the gas sensor and the electronic controller form a signal connection, wherein the air pressure monitoring module is correspondingly arranged on the tire side and can detect the air pressure of the tire's inflatable cavity.
[0156] Alternatively, the air pressure monitoring module of the present application may also be constructed as an independent air pressure monitoring controller for separately monitoring the air pressure of the to-be-inflated cavity of the tire.
[0157] At least one air pressure monitoring sensor is provided at each tire. The tire pressure of each tire can be collected by the air pressure monitoring sensor and directly sent to the air pressure monitoring module of the electronic controller via a wireless transmission signal to adjust the corresponding inflation pressure.
[0158] In some embodiments, in order to provide a stable inflation pressure to the tire or the inflated object so that the tire and the inflated object can reach a preset pressure value, the air pressure control system 10 further includes: an air pump.
[0159] The air pump is used to adjust the inflation pressure.
[0160] Exemplarily, the air pump of the present application forms a signal connection with the electronic controller, and the air pump can respectively form a passage connection with the valve of the tire and the valve of the object to be filled, so that the gas generated by the air pump can be transported along the passage to the valve of the tire and inflate the tire, or transported to the valve of the object to be filled and inflate the object.
[0161] It should be noted that no direct electrical signal connection is established between the electronic controller of the present application and the valve of the tire. The electronic controller mainly controls the on and off of the air pump. The gas pressure generated by the air pump acts as the inflation pressure on the valve of the tire, thereby making the valve of the tire have an opening that matches the inflation pressure so that the valve of the tire can open.
[0162] In the present application, the valve of the tire and the valve of the inflated object share a common air pump, which can simplify the overall structure of the air pressure control system 10 and improve the integration of the air pressure control system 10.
[0163] A tire valve is arranged at each tire of the vehicle, and the valves of all tires share one air pump.
[0164] In some embodiments, the air pressure control system 10 also includes an electromagnetic air valve, which is arranged between the tire valve and the air pump. The electromagnetic air valve is connected to the tire valve and the air pump through a passage, and the electromagnetic air valve is signal-connected to an electronic controller. The electronic controller controls the power on and off of the electromagnetic air valve and the air pump.
[0165] Among them, the electronic controller directly controls the switching state of the solenoid valve by controlling the power-on state of the coil in the solenoid valve. A central pipeline is provided between the air pump and the solenoid valve, a first air path is provided between the solenoid valve and the valve of the tire, and a second air path is provided between the valve of the tire and the cavity to be inflated of the tire. The solenoid valve can control the connection and disconnection of the central air path and the first air path, and the valve of the tire controls the connection and disconnection of the first air path and the second air path, thereby controlling the connection and disconnection of the cavity to be inflated of the tire and the central air path.
[0166] It should be noted that the second air circuit can specifically be a passage of the tire valve. When the opening of the tire valve is not at a fully closed opening, the second air circuit is connected to allow the tire valve to be inflated or deflated. When the tire valve is at a fully closed opening, the second air circuit is cut off to stop the inflation or deflation of the tire.
[0167] In some embodiments, the solenoid valves of each tire can be integrated together, for example, the solenoid valves are integrated into a shell, and then the shell is provided with a corresponding flow path. The technical solution that the solenoid valves of each tire can be integrated together is not the focus of protection of this application, so it will not be elaborated here.
[0168] Similarly, the controller, the integrated solenoid valve, and the air pump may be integrated into one assembly in pairs, or the three may be integrated into one assembly, which may be installed on the chassis, trunk, or front cabin of the vehicle.
[0169] In the embodiment of the present application, after the tire is inflated and deflated, the air pressure of the entire air circuit can be adjusted by detecting whether the ambient air pressure of the central air circuit has dropped to the ambient target air pressure, thereby completing the adjustment of the air pressure of the tire.
[0170] It should be noted that the environmental target air pressure is lower than the first target tire pressure.
[0171] In some embodiments, the air pressure control system 10 also includes a control panel, which is connected to the electronic controller via the vehicle CAN bus signal, and the control panel is also integrated with a passage that can form a gas circuit between the valve of the filled object and the external atmosphere and the filled object.
[0172] According to a fourth aspect of the present application, a tire pressure adjustment method is provided, referring to Figure 7 ,include:
[0173] S410: continuously inflating the tire when the tire valve is at the maximum opening or continuously deflating the tire when the tire valve is at the transition opening;
[0174] S420: When the air pressure of the tire reaches a preset threshold, releasing the opening lock of the tire valve.
[0175] In some embodiments, the tire pressure adjustment method of the present application further includes:
[0176] By adjusting the inflation pressure, the inflation pressure can make the valve of the tire have an opening adapted to the inflation pressure.
[0177] In step 410, the inflation pressure is adjusted to the fully open pressure, so that the valve of the tire can be located at the maximum opening under the action of the inflation pressure, and then the tire is continuously inflated when the valve of the tire is located at the maximum opening.
[0178] In step 410, the inflation pressure is adjusted to the transition pressure so that the tire valve can be located at the transition opening under the action of the inflation pressure, and then the tire is continuously deflated when the tire valve is located at the transition opening. Inflation can also be stopped when the tire valve is located at the transition opening. Stopping inflation at this time is to perform the tire pressure maintenance action.
[0179] The valve of the tire of the present application is in a locked state when it is at the maximum opening and the transitional opening, wherein the locking of the tire valve at the maximum opening is achieved by the inflation air pressure, and the locking of the tire valve at the transitional opening is physically locked by mechanical means.
[0180] By adjusting the inflation pressure, the valve of the tire can have an adaptive opening, and the lock of the valve of the tire can also be released.
[0181] Then in step S420, when the air pressure of the tire reaches a preset threshold, the opening lock of the valve of the tire is released, wherein when the valve of the tire is in a transitional opening and the air pressure of the tire reaches a first target tire pressure, the transitional locking state of the valve is released with a first unlocking air pressure greater than the transitional air pressure;
[0182] When the valve 100 of the tire is at the maximum opening and the tire reaches the second target tire pressure, the fully open locking state of the valve is released with a second unlocking air pressure that is less than the fully open air pressure.
[0183] It should be noted that during the inflation and deflation process of the tire, the tire valve opening is switched from the minimum opening to the maximum opening, then to the transition opening, and then to the maximum opening, and finally from the maximum opening back to the minimum opening. When the tire valve is at the minimum opening, the corresponding inflation pressure is the full-closed pressure, the full-closed pressure is zero, or the applied inflation pressure is not enough to overcome the force acting on the tire valve, thereby allowing the tire valve to remain at the minimum opening so that the tire valve is in a fully closed state.
[0184] Among them, when the tire is deflated, it is necessary to adjust the inflation pressure to the fully open pressure so that the tire valve switches from the minimum opening to the maximum opening, and then use a second unlocking pressure that is less than the fully open pressure to release the fully open locking state of the valve. At this time, the opening of the tire valve will switch from the maximum opening to the transition opening.
[0185] Exemplarily, the second unlocking air pressure can be a transitional air pressure, which can keep the tire valve at a transitional opening. The second unlocking air pressure can be zero, or other values, that is, the applied inflation pressure is not sufficient to overcome the force acting on the tire valve, thereby being able to switch from the maximum opening to the transitional opening or the minimum opening.
[0186] According to a fifth aspect of the present application, a tire pressure adjustment method is provided, referring to Figure 8 ,include:
[0187] Step S510: setting the tire inflation pressure to a transition pressure to trigger and maintain a valve locking state;
[0188] Step S520: setting the inflation pressure of the tire to the full-open pressure to inflate the tire in a locked state of the valve;
[0189] Step S530: Control the inflation pressure of the valve to be an unlocking pressure to release the valve from a locked state.
[0190] In the process of inflating the tire, step S520 is first executed to make the inflation pressure of the tire fully open so as to inflate the tire with an inflation pressure greater than the transition pressure under the locked state of the valve. After the tire pressure reaches a certain tire pressure value, step S510 is then executed to gradually reduce the inflation pressure to the transition pressure so that the opening of the tire valve can be switched from the maximum opening to the transition opening. At this time, the tire is stopped from being inflated, and the tire valve is physically maintained at the transition opening, and the tire pressure in the tire is reduced by a certain amount. When the tire pressure is reduced to the first target pressure, step 530 is executed to release the transition locking state of the valve with a first unlocking pressure greater than the transition pressure. At this time, step S520 can be executed again to continue to inflate the tire with the full-open pressure. When the tire pressure reaches the second target pressure, the full-open locking state of the valve is released with a second unlocking pressure less than the full-open pressure. At this time, the inflation pressure is reduced to the full-closed pressure, so that the valve opening of the tire is switched from the maximum opening to the minimum opening, thereby completing the inflation of the tire.
[0191] In another embodiment, during the deflation of the tire, step S520 is first executed to make the inflation pressure of the tire a fully open pressure so that the tire is inflated with an inflation pressure greater than the transition pressure in the locked state of the valve. At this time, step S510 is executed again to gradually reduce the inflation pressure to the transition pressure so that the opening of the tire valve can be switched from the maximum opening to the transition opening. At this time, inflating the tire is stopped, and the tire valve uses a physical method to maintain the transition opening. The tire pressure in the tire will continue to decrease and be deflated. When the tire pressure is reduced to the first target tire pressure, step 530 is executed to release the transition locking state of the valve with a first unlocking pressure greater than the transition pressure. At this time, step S520 can be executed again to continue to inflate the tire with the fully open pressure. When the tire pressure reaches the second target tire pressure, the fully open locking state of the valve is released with a second unlocking pressure less than the fully open pressure. At this time, the inflation pressure is reduced to the fully closed pressure so that the valve opening of the tire will switch from the maximum opening to the minimum opening, and the deflation of the tire is completed.
[0192] Among them, during the inflation and deflation process of the tire, the first target tire pressure is lower than the second target tire pressure, which provides a certain margin for the inflation and deflation of the tire and avoids over-inflation and deflation.
[0193] According to a sixth aspect of the present application, a tire valve is provided, referring to Fig. 9 , Fig.10 , Fig.11 , the valve of the tire includes a valve core.
[0194] The valve core is configured to enable the valve to have an adaptive state and a locked state.
[0195] The valve core has a plurality of different positions so that the valve has a plurality of different openings;
[0196] When the tire valve is in the adaptive state, the position of the valve core is coupled with the force generated by the air pressure inside the tire valve;
[0197] When the valve of the tire is in a locked state, the position of the valve core is decoupled from the force generated by the air pressure inside the valve of the tire.
[0198] In some embodiments, the position of the valve core includes:
[0199] A fully open position 12a and a transition position 12b;
[0200] When the valve core is in the fully open position 12a, the valve of the tire is at the maximum opening, and when the valve core is in the transition position 12b, the valve of the tire is at the transition opening;
[0201] If the tire pressure reaches the preset target tire pressure, the position of the valve core is switched from the fully open position 12a to the transition position 12b.
[0202] In some embodiments, the position of the valve core includes:
[0203] Fully closed position 12c;
[0204] When the valve core is in the fully closed position 12c, the tire valve is at the minimum opening;
[0205] When the valve core is in the transition position 12b and the tire reaches the first target tire pressure, the position of the valve core is switched from the transition position 12b to the fully open position 12a and then to the fully closed position 12c.
[0206] The preset target tire pressure is greater than the first target tire pressure, which allows the tire pressure to have a certain degree of buffering to avoid over-inflation and deflation.
[0207] It should be noted that the tire valve has an adaptive state, which means that the position of the valve core will change under the action of the inflation pressure, and the valve has a locked state, which means that the position of the valve core will not change under the action of the inflation pressure. At this time, the position of the valve core can be changed mainly by adjusting the inflation pressure value.
[0208] refer to Figures 10 to 14 The tire valve includes a valve body 110 , a valve core 120 and an actuating assembly 130 .
[0209] The valve body 110 has a valve chamber 11 a and a passage 11 b .
[0210] The valve core 120 and the actuating assembly 130 are located in the valve chamber 11 a.
[0211] The medium can be introduced into or discharged from the device to be operated along the passage 11b. The medium can be liquid or gas. The device to be operated can be a tire, an airbag, a pipe, or other device that needs to introduce or discharge the medium. The medium in this application is constructed as gas, and the device to be operated is constructed as a tire.
[0212] The valve core 120 is located in the valve cavity 11 a and is movably connected to the valve body 110 , so that the valve core 120 has at least a fully open position 12 a , a transition position 12 b and a fully closed position 12 c relative to the valve body 110 .
[0213] Among them, when the valve core 120 is in the fully open position 12a, the tire valve is at the maximum opening, when the valve core 120 is in the transition position 12b, the tire valve is at the transition opening, and when the valve core 120 is in the fully closed position 12c, the tire valve is at the minimum opening.
[0214] The actuating assembly 130 is located in the valve cavity 11 a and is used to cooperate with the inflation air pressure to actuate the valve core 120 to switch between the fully open position 12 a, the transition position 12 b and the fully closed position 12 c when in use.
[0215] When the valve core 120 is in the fully open position 12a and the transition position 12b, the passage 11b is connected, and the connected passage 11b is used for the medium to be introduced or discharged along the passage 11b.
[0216] When the valve core 120 is in the fully closed position 12c, the passage 11b is disconnected, and the medium cannot be introduced into or discharged from the passage 11b after the passage 11b is disconnected.
[0217] Through the above technical solution, the valve core 120 is actuated by the actuating assembly 130 to switch between the fully open position 12a, the transition position 12b and the fully closed position 12c, thereby realizing the self-opening and closing of the tire valve 100, thereby automatically completing the introduction or discharge of gas, and realizing the inflation and deflation of the tire, without the operator's participation in the inflation and deflation of the tire. The tire pressure can be adjusted by inflation and deflation so that the tire pressure is within an appropriate range, and the vibration and jumping of the vehicle 1 during driving can also be reduced, thereby improving the ride comfort of the vehicle 1, and the driver can adjust the tire pressure according to road conditions and passenger needs to ensure the best ride comfort experience.
[0218] In some embodiments, a medium is introduced into the passage 11 b to generate a communication force that causes the passage 11 b to communicate.
[0219] Specifically, the medium is gas. After the gas is introduced into the passage 11b, the pressure of the gas itself acts as a connecting force to connect the passage 11b. The connecting force acts on the valve core 120, so that the valve core 120 can move in the valve cavity 11a relative to the valve body 110. By using the pressure of the medium itself as the connecting force to connect the passage 11b, the structure is simple, the passage 11b can be connected without the help of external tools, and the operation is convenient.
[0220] The effect of adjusting the inflation pressure is achieved by adjusting the amount of gas introduced into the passage 11b, that is, the effect of adjusting the connecting force can be achieved.
[0221] In some embodiments, reference Figures 15 to 22 The valve body 110 has a central axis 11c, and the valve core 120 forms an axial sliding connection along the central axis 11c relative to the valve body 110. At this time, the inflation pressure is adjusted to the full-open pressure or the transition pressure, and the connecting force of the air pressure acts on the valve core 120, which can make the valve core 120 move axially along the central axis 11c to the full-open position 12a or the transition position 12b relative to the valve body 110.
[0222] By forming an axial sliding connection of the valve core 120 with the center axis 11c, after the connecting force acts on the valve core 120, the valve core 120 is driven to slide in the valve cavity 11a, thereby achieving the effect of switching the position of the valve core 120. The sliding method is simple and easy to use, and has less space requirements than the traditional valve rotation opening method.
[0223] In some embodiments, reference Figures 15 to 22 The actuating assembly 130 includes an actuating connecting member 131 and an actuating reversing portion 132 .
[0224] The actuation connection member 131 is connected to the valve body 110 , and the actuation switching portion 132 is formed or connected to the valve core 120 .
[0225] Part of the actuating connecting member 131 and part of the actuating reversing portion 132 form a movable connection.
[0226] The movable connection refers to the connection between part of the actuating connecting member 131 and part of the actuating reversing portion 132. When part of the actuating connecting member 131 slides along the actuating reversing portion 132, the actuating connecting member 131 will also rotate relative to the valve core 120 where the actuating reversing portion 132 is located.
[0227] Specifically, when the valve core 120 is acted upon by the connecting force, the valve core 120 will move along the valve cavity 11a. At this time, the valve core 120 will generate a driving force to drive the actuating connection 131 to move along the valve cavity 11a. Under the action of the driving force, part of the connection of the actuating connection 131 will be connected to the actuating reversing part 132 on the valve core 120.
[0228] When the valve core 120 moves to the fully open position 12a and the transition position 12b, part of the actuating connection member 131 will slide along the actuating reversing portion 132 and since the valve core 120 is constructed to slide relative to the valve body 110, the actuating connection member 131 will slide along the actuating reversing portion 132 and will also rotate around the valve core 120 where the actuating reversing portion 132 is located. After the rotation, part of the actuating connection member 131 will remain connected to the actuating reversing portion 132, so that the valve core 120 remains in the fully open position 12a or the transition position 12b under the action of the connecting force.
[0229] The connecting force generated by the gas can be partially reduced, so that part of the actuating connector 131 is disconnected from the actuating reversing portion 132. Generally, part of the actuating connector 131 will not be disconnected from the actuating reversing portion 132.
[0230] In some special cases, for example, when the amount of gas is insufficient and the generated connecting force is insufficient, part of the actuating connector 131 will be disconnected from the actuating reversing portion 132, and the amount of gas needs to be increased.
[0231] When the valve core 120 needs to be switched from the fully closed position 12c to the fully open position 12a and from the fully open position 12a to the fully closed position 12c or the transition position 12b, part of the actuating connection member 131 will remain connected to the actuating reversing portion 132 to facilitate the application of a driving force to part of the actuating connection member 131.
[0232] In some embodiments, reference Fig.13 The actuating reversing portion 132 has a reversing surface 132 a that contacts the actuating connecting member 131 in the axial direction of the central axis 11 c.
[0233] The reversing surface 132a is configured as a plane, and a portion of the actuating connecting member 131 can move along the reversing plane, so that the reversing of the actuating connecting member 131 is smoother and more stable.
[0234] In some embodiments, reference Fig.13 The actuating assembly 130 further includes an actuating guide portion 133 .
[0235] The actuation guide portion 133 is formed on the inner peripheral wall surface of the valve body 110 , and the actuation guide portion 133 is used to guide the actuation link 131 to move axially along the central axis 11 c .
[0236] When the valve core 120 switches between the fully open position 12 a , the transition position 12 b and the fully closed position 12 c , the actuating connecting member 131 is selectively connected to or disconnected from the actuating guiding portion 133 .
[0237] When the valve core 120 is in the fully closed position 12c, part of the actuating connecting member 131 is connected to the actuating guide portion 133. When the valve core 120 switches from the fully closed position 12c to the fully open position 12a, part of the actuating connecting member 131 moves along the actuating guide portion 133 until it is disconnected from the actuating guide portion 133.
[0238] Part of the actuating connecting member 131 will move along the actuating guide portion 133 until it is disconnected from the actuating guide portion 133, and part of the actuating connecting member 131 will also remain connected to the actuating reversing portion 132, and the actuating connecting member 131 and the actuating reversing portion 132 will remain relatively stationary.
[0239] After part of the actuating connecting member 131 is disconnected from the actuating guide portion 133, the part of the actuating connecting member 131 will move along the actuating reversing portion 132. In the process of moving the part of the actuating connecting member 131 along the actuating reversing portion 132, the part of the actuating connecting member 131 will also rotate around the central axis 11c relative to the valve core 120 where the actuating reversing portion 132 is located, thereby completing the process of switching the actuating connecting member 131 from the fully closed position 12c to the open position.
[0240] Specifically, the actuating guide portion 133 is constructed as a groove structure with a groove bottom opened on the inner circumferential wall surface of the valve body 110 along the axial direction of the central axis 11c of the valve body 110. Part of the actuating connector 131 will move along the actuating guide groove constructed as a groove structure, and part of the actuating connector 131 will withdraw from the groove structure to disconnect from the actuating guide portion 133.
[0241] Exemplarily, a long protrusion 122 can be opened on the outer wall surface of the valve core 120, and part of the long protrusion 122 is located in the actuating guide portion 133. The long protrusion 122 and the actuating connector 131 share the actuating guide portion 133, and there is no need to open additional components, thereby ensuring that the valve core 120 can slide axially along the center axis 11c in the valve cavity 11a.
[0242] In order to enable a portion of the actuating connecting member 131 to remain stationary relative to the actuating reversing portion 132 during the process of the valve core 120 switching from the fully closed position 12c to the fully open position 12a along the axial direction of the central axis 11c, or switching from the fully open position 12a to the fully closed position 12c or the transition position 12b, in some embodiments, the first projection of the actuating reversing portion 132 on the central axis 11c is partially overlapped with the second projection of the actuating guide portion 133 on the central axis 11c.
[0243] refer to Figures 15 to 20 The projections of the actuating reversing portion 132 and the actuating guiding portion 133 on the inner peripheral wall surface partially overlap.
[0244] In some embodiments, the actuating assembly 130 further includes an actuating stop 134 .
[0245] The actuation limiter 134 is formed to the inner peripheral wall surface of the valve body 110 .
[0246] Part of the actuating connector 131 is selectively connected to or disconnected from the actuating limit portion 134 .
[0247] When part of the actuating connecting member 131 is disconnected from the actuating guide portion 133, part of the actuating connecting member 131 will also move along the actuating reversing portion 132 to connect with the actuating limiting portion 134, and the actuating limiting portion 134 is used to limit the actuating connecting member 131 so that the valve core 120 can be maintained in the fully open position 12a or the transition position 12b.
[0248] The actuation limit portion 134 is configured as a protrusion on the inner peripheral wall of the valve body 110 , and a portion of the actuation connection member 131 can abut against the end of the protrusion, so that the valve core 120 is maintained in the fully open position 12 a or the transition position 12 b .
[0249] In some embodiments, reference Fig.17 and Fig.19 , the opening and closing member is located at the fully open position 12a and the transition position 12b.
[0250] refer to Fig.16 , Fig.18 and Fig. 20 The actuation limit portion includes a first type of actuation limit portion 1341 and a second type of actuation limit portion 1342 .
[0251] The first type of actuation limiting portion 1341 is used to limit the valve core 120 at the fully open position 12a, and the second type of actuation limiting portion 1342 is used to limit the valve core 120 at the transition position 12b.
[0252] Part of the actuating connector 131 is selectively connected to or disconnected from the first type actuating limit portion 1341 or the second type actuating limit portion 1342 .
[0253] Exemplarily, when part of the actuating connector 131 is connected to the first type of actuating limiter 1341 , the valve core 120 is located at the fully open position 12 a .
[0254] When the valve core 120 is located in the fully open position 12a, the actuating reversing portion 132 applies a driving force to the actuating connecting member 131, so that the actuating reversing portion 132 can slide along the first type of actuating limit portion 1341 to the second type of actuating limit portion 1342, so that the first type of actuating limit portion 1341 remains connected to the second type of actuating limit portion 1342, thereby switching the valve core 120 from the fully open position 12a to the transition position 12b.
[0255] More specifically, part of the actuation connector 131 may be abutted against the first type actuation limit portion 1341 , or may be abutted against the first type actuation limit portion 1341 .
[0256] The end of the first type actuation limiting portion 1341 is connected to the end of the second type actuation limiting portion 1342 in a smooth transition.
[0257] In the radial direction around the central axis 11 c , the inner circumferential wall surface of the valve body 110 is provided with two or more first-type actuation limit portions 1341 and second-type actuation limit portions 1342 .
[0258] In some embodiments, reference Fig.21 and Fig. 22 Two different and adjacent first-type actuation limit portions 1341 are provided with a second-type actuation limit portion 1342 , and another two different and adjacent first-type actuation limit portions 1341 are provided with an actuation guide portion 133 .
[0259] For example, reference Fig.21 and Fig. 22 A first type actuation limiting portion 1341 is provided between the actuation guiding portion 133 and the second type actuation limiting portion 1342 .
[0260] When the valve core 120 is in the fully closed position 12c, part of the actuating connector 131 is connected to the actuating guide portion 133. After the valve core 120 is subjected to the connecting force of the inflation pressure being the fully open pressure, the valve core 120 will slide along the valve cavity 11a and drive part of the actuating connector 131 to move along the actuating guide portion 133. After the valve core 120 slides to the fully open position 12a, part of the actuating connector 131 will slide along the actuating reversing portion 132 and rotate relative to the valve core 120 until part of the actuating connector 131 slides to the first type of actuating limit portion 1341. Under the action of the connecting force, part of the actuating connector 131 can remain in contact with the first type of actuating limit portion 1341, and at this time, the tire is inflated to a certain extent.
[0261] After completing a certain degree of inflation, the valve core 120 needs to be switched from the fully open position 12a to the transition position 12b, and the inflation pressure is adjusted to be less than the fully open pressure to unlock the fully open locked state of the tire valve. For example, the inflation pressure is adjusted to zero, and the connecting force acting on the valve core 120 is cancelled, so that part of the actuating connector 131 slides along the first type of actuating limit portion 1341 to the second type of actuating limit portion 1342.
[0262] When part of the actuating connector 131 is connected to the second type of actuating limiter 1342 , the valve core 120 will not directly switch from the fully open position 12a back to the fully closed position 12c , and the pressure-maintaining operation of the tire that needs to be inflated or deflated can be performed.
[0263] It should be noted that after the valve core 120 switches from the fully open position 12a to the transition position 12b, the inflation pressure is adjusted to the fully open pressure. At this time, by introducing gas into the passage 11b, the force generated by the gas will act on the valve core 120, so that the valve core 120 can be switched back from the transition position 12b to the fully open position 12a, and then the introduction of gas is stopped. The valve core 120 then switches from the fully open position 12a to the fully closed position 12c, completing the switching of the valve core 120 from the open position to the fully closed position 12c.
[0264] When the valve core 120 switches between various positions, the valve core 120 will first slide to the left to the fully open position 12a. When the fully open position 12a is switched to the transition position 12b, the valve core 120 will slide from left to right. When the transition position 12b is switched to the fully open position 12a, the valve core 120 will slide from right to left. When the fully open position 12a is switched to the fully closed position 12c, the valve core 120 will slide from left to right.
[0265] When the valve core 120 is located at the fully open position 12a, the valve core 120 slides along the valve cavity 11a to the leftmost end where the valve core 120 can slide leftward. At this time, the opening of the tire valve 100 is at the maximum opening.
[0266] In some embodiments, reference Fig.21 and Fig. 22 The first type actuation limit portion 1341 and the second type actuation limit portion 1342 are constructed as a rotating body with the central axis 11c as the rotation axis.
[0267] Specifically, the first type actuation limit portion 1341 and the second type actuation limit portion 1342 are configured such that the arc lengths of the rotating bodies are the same.
[0268] In some embodiments, reference Fig.21 and Fig. 22By making the axial length of the first projection of the first type of actuating limit portion 1341 on the central axis 11c greater than the axial length of the second projection of the second type of actuating limit portion 1342 on the central axis 11c, the valve core 120 can switch between the fully open position 12a and the transition position 12b by switching the connection with the actuating limit portions of different lengths. This method of switching the opening position is smooth and stable.
[0269] refer to Fig.21 and Fig. 22 The axial end side surface of the second type actuation limit portion 1342 extends obliquely from two different first type actuation limit portions 1341 from one first type actuation limit portion 1341 to the other first type actuation limit portion 1341 .
[0270] The inclination angle and direction of the second-type actuation limit portion 1342 between two different first-type actuation limit portions 1341 and another second-type actuation limit portion 1342 between another two different first-type actuation limit portions 1341 are set to be the same.
[0271] In some embodiments, reference Fig.12 The actuating connecting member 131 forms or is connected with an actuating connecting arm 1311 .
[0272] Each actuating connecting arm 1311 is arranged around the central axis 11c.
[0273] The actuating connecting member 131 includes a cylindrical body 1312 , and the actuating connecting arm 1311 is disposed on the cylindrical body 1312 around the central axis 11 c .
[0274] Among them, reference Fig.16 The shaft end of the actuating connecting arm 1311 and the actuating reversing portion 132 are configured to have a gap g.
[0275] The gap g is used to enable the shaft end of the actuating connecting arm 1311 to move relative to the actuating reversing portion 132 .
[0276] That is to say, it can be understood that: when the valve core 120 is in the fully closed position 12c, the actuating connecting arm 1311 contacts the reversing surface 132a, and the axial end of the actuating connecting arm 1311 extends to the middle section of the reversing surface 132a. In this position, there is a gap g between the axial end of the actuating connecting arm 1311 and the actuating reversing portion 132, so that the axial end of the actuating connecting arm 1311 can move relative to the actuating reversing portion 132, allowing the valve core 120 to switch from the fully closed position 12c to the fully open position 12a.
[0277] It should be noted that when the valve core 120 is located at the fully closed position 12c, there is a gap g between the shaft end of the actuating connecting arm 1311 and the actuating reversing portion 132;
[0278] When the valve core 120 switches from the fully closed position 12c to the open position, when the shaft end of the actuating connecting arm 1311 moves along the reversing surface 132a, the space of the gap g is gradually reduced.
[0279] When the valve core 120 switches from the open position to the fully closed position 12 c , the space of the gap g is gradually expanded as the axial end of the actuating connecting arm 1311 moves along the reversing surface 132 a .
[0280] In some embodiments, reference Fig.13 The valve core 120 is constructed as a rotating body with the central axis 11 c as the rotation axis. Along the axial direction of the central axis 11 c, the actuating reversing portion 132 is constructed as a groove structure at the end of the valve core 120.
[0281] Exemplarily, the interval g is the space between the bottom of the groove structure and the axial end of the actuating connecting arm 1311 .
[0282] The two side walls of the groove structure serve as two reversing surfaces 132a.
[0283] In some embodiments, reference Fig.11 and Fig.21 The actuating assembly 130 further includes an actuating reset member 135 .
[0284] The actuating reset member 135 is located in the valve cavity 11 a and is used to bias the actuating connecting member 131 to approach the valve core 120 , thereby utilizing the actuating connecting member 131 to drive the valve core 120 to switch from the open position to the fully closed position 12 c .
[0285] Exemplarily, the actuation restoring member 135 surrounds the cylinder 1312 of the actuation connecting member 131 and abuts against the cylinder 1312 .
[0286] The actuating reset member 135 can bias the actuating connection member 131, thereby making the actuating connection member 131 tend to approach the valve core 120, and gas is introduced into the passage 11b. Under the connecting force generated by the gas, the passage 11b is opened, and the driving force applied by the valve core 120 to the actuating connection member 131 can overcome the biasing force applied by the actuating reset member 135 to the actuating connection member 131, thereby making the actuating connection member 131 able to slide to the left axially along the center axis 11c in the valve cavity 11a to an open position.
[0287] When the valve core 120 is separated from the valve plug 113 under the action of inflation air pressure, the valve core 120 will move along the valve cavity under the action of air pressure, and when it is located in the fully open position 12a or the transition position 12b, part of the actuating connection 131 is connected to the actuating limit portion, and the actuating limit portion will prevent the actuating connection 131 from moving axially to the right along the center axis 11c to prevent the valve core 120 from sliding to the fully closed position 12c.
[0288] When the inflation and deflation are completed, the introduction of gas into the passage 11b is stopped, and the connecting force applied by the air pressure on the valve core 120 is eliminated. At this time, the biasing force applied by the actuating reset member 135 to the actuating connecting member 131 will also act on the valve core 120. Under the action of the biasing force, the valve core 120 slides to the right along the axial direction of the center axis 11c in the valve cavity 11a to the fully closed position 12c.
[0289] The actuating reset member 135 is used to realize automatic reset of the valve core 120 and enable the valve core 120 to be maintained at the fully closed position 12 c.
[0290] In some embodiments, at least a portion of the actuation reset member 135 surrounds the actuation connection member 131 and is connected to the actuation connection member 131 .
[0291] Exemplarily, the actuation return element 135 is configured as a cylindrical spring.
[0292] Of course, the actuating reset member 135 may also be constructed as other components capable of generating biasing force, such as a disc spring or compressible rubber.
[0293] In some embodiments, the actuating assembly 130 further includes a position-limiting portion 136 .
[0294] The in-position limiting portion 136 is located in the valve cavity 11 a , wherein at least a portion of the actuating reset member 135 surrounds the in-position limiting portion 136 .
[0295] By utilizing the in-position limiting portion 136 , it is possible to prevent the actuating connecting member 131 from excessively moving to the left.
[0296] In some embodiments, the tire valve 100 further includes a seal 141 .
[0297] The sealing member 141 is located in the valve cavity 11a to seal between the actuating connector 131 and the valve cavity 11a, thereby ensuring the sealing effect between the actuating connector 131 and the position-limiting portion 136, and further ensuring the efficiency of inflation and deflation.
[0298] The sealing member 141 surrounds at least a portion of the actuating connector 131 .
[0299] An annular groove 123 is formed on the outer peripheral surface of the actuating connector 131 , and a portion of the sealing member 141 is located in the annular groove 123 , and a portion of the sealing member 141 is pressed against the inner peripheral wall surface of the valve cavity 11 a .
[0300] The seal 141 is configured as a sealing ring, and the valve core 120 is configured as a piston.
[0301] In some embodiments, the passage 11b includes a first type passage 11b1 and a second type passage 11b2.
[0302] Among them, the first type of passage 11b1 is formed on the valve body 110 along the axial direction of the central axis 11c, and the second type of passage 11b2 is formed on the valve body 110 along the radial direction of the central axis 11c. At least part of the valve core 120 is located at the intersection of the first type of passage 11b1 and the second type of passage 11b2 to connect or disconnect the passage.
[0303] The second type passage 11b2 is connected to the tire cavity of the tire, and the first type passage 11b1 is selectively connected to the atmosphere or the central air path.
[0304] When the tire needs to be inflated, the gas generated by the air pump 800 enters the first type of passage 11b1 through the central air path, then enters the second type of passage 11b2 along the first type of passage 11b1, and then enters the tire cavity for inflation.
[0305] When the tire needs to be deflated, the first type passage 11b1 is connected to the atmosphere, and the gas in the tire cavity enters the first type passage 11b1 along the second type passage 11b2, and is then output to the atmosphere for deflation.
[0306] By way of example, the valve core 120 has a rubber body 121 at the shaft end thereof.
[0307] The valve body 110 includes a valve cover 111 , a valve seat 112 and a valve plug 113 . The valve seat 112 is located between the valve cover 111 and the valve plug 113 .
[0308] The valve seat 112 has a cavity with openings at both ends, the valve cover 111 has a cavity with an opening at one end, the valve cover 111 is cooperatively connected with the valve seat 112, the cavity of the valve seat 112 and the cavity of the valve cover 111 form a valve cavity 11a for accommodating the valve core 120, the actuating assembly 130 and the actuating reset member 135, and part of the valve plug 113 is extended into the valve cavity 11a.
[0309] The valve seat 112 has a horizontal portion and a vertical portion, and the vertical portion is perpendicular to the axial direction of the central axis 11 c.
[0310] The cavity of the valve seat 112 is opened on the horizontal portion, the second type passage 11b2 is opened on the vertical portion, and the first type passage 11b1 is opened on the valve plug 113 along the axial direction of the central axis 11c.
[0311] Along the radial direction of the central axis 11c, the cross-sectional area of the rubber body 121 at the axial end of the valve core 120 is larger than the cross-sectional area of the first type of passage 11b1 of the valve plug 113, and the rubber body 121 is directly opposite to the first type of passage 11b1 of the valve cover 111. Therefore, when the rubber body 121 on the valve core 120 abuts against the valve plug 113, the valve core 120 is located in the fully closed position 12c, and the first type of passage 11b1 and the second type of passage 11b2 are disconnected.
[0312] When the valve core 120 is separated from the valve plug 113 under the action of the inflation pressure, the first type of passage and the second type of passage 11b2 are connected to allow the tire to be inflated or deflated.
[0313] When the valve core 120 is located at the transition position 12b, the gas in the tire will overflow, and a deflation operation can be performed at this time, or the tire can be inflated during one of the processes.
[0314] At this time, if the tire needs to be inflated, it is necessary to stop inflating the tire so that the gas in the tire can be released again, and then inflate the tire with full pressure. The valve core will switch from the transition position 12b to the full open position 12a to avoid over-inflation.
[0315] It should be noted that, during the process of inflating the tire, the time that the valve core 120 is located at the transition position 12b will not be very long, for example, less than the time that the valve core is located at the fully open position 12a.
[0316] If the tire needs to be deflated, the valve core 120 needs to be switched from the fully closed position 12c to the fully open position 12a, and then to the transition position 12b. In the transition position 12b, the tire is deflated. After the deflation is completed, the tire is inflated with full air pressure. At this time, the valve core will switch from the transition position 12b to the fully open position 12a. At this time, inflating the tire is stopped, and the valve core will switch from the fully open position 12a to the fully closed position 12c, completing the deflation of the tire.
[0317] Among other things, inflating the tire with full air pressure can also avoid excessive deflation.
[0318] It should be noted that, during the process of deflating the tire, the time that the valve core 120 is located at the fully open position 12a will not be very long, for example, less than the time that the valve core is located at the transition position 12b.
