The power supply inside the sensor and the transmission of sensor acquisition signals are the key to the normal operation of smart tires. The traditional tire pressure monitoring system (TPMS) has a low sampling frequency and low power consumption, and its built-in button battery and antenna can meet the needs. However, with the continuous expansion of the functions of smart tires, the frequency of acquisition and transmission has increased, and the power consumption has increased significantly.

[0003] At present, the power supply of smart tires mainly consists of placing large-capacity batteries and generating electricity inside the tires. However, with the continuous development of technology, the service life of tires has also been greatly improved. The built-in large-capacity power supply battery cannot meet the growing power supply needs of smart tires. Batteries need to be replaced frequently. During the battery replacement process, the tires must be disassembled and installed. The entire battery replacement process is very cumbersome and may also cause artificial damage to the smart tires. In addition, as the battery capacity increases, its volume and weight also increase, and the dynamic balance of the tire after rotation cannot be guaranteed.

[0004] Secondly, the power supply inside the tire is mainly friction power generation, and its power generation is small. For smart tires with built-in strain and acceleration sensors, its power generation is far from meeting actual needs.

[0005] It can be seen that the existing technology cannot continuously supply power to smart tires for a long time. There are problems such as cumbersome battery replacement process and insufficient internal power generation, which cannot guarantee the power supply requirements of the sensor chip.

[0024] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0025] Existing smart tires are embedded or built-in sensor devices. The power supply inside the sensor and the transmission of sensor acquisition signals are the key to the normal operation of smart tires. Traditional tire pressure monitoring systems have low sampling frequency and low power consumption, and their built-in button batteries and antennas can meet the needs. However, with the continuous expansion of the functions of smart tires, their acquisition and transmission frequencies have increased, and power consumption has increased significantly.

[0026] At present, the power supply of smart tires mainly consists of placing large-capacity batteries and generating electricity inside the tires. However, with the continuous development of technology, the service life of tires has also been greatly improved. The built-in large-capacity power supply battery cannot meet the growing power supply needs of smart tires. Batteries need to be replaced frequently. During the battery replacement process, the tires must be disassembled and installed. The entire battery replacement process is very cumbersome and may also cause artificial damage to the smart tires. In addition, as the battery capacity increases, its volume and weight also increase, and the dynamic balance of the tire after rotation cannot be guaranteed.

[0027] Secondly, the power supply inside the tire is mainly friction power generation, and its power generation is small. For smart tires with built-in strain and acceleration sensors, its power generation is far from meeting actual needs.

[0028] It can be seen that the existing technology cannot continuously supply power to smart tires for a long time. There are problems such as cumbersome battery replacement process and insufficient internal power generation, which cannot guarantee the power supply requirements of the sensor chip.

[0029] Therefore, the embodiment of the present application provides a valve auxiliary device, which is applied to a smart tire, such as Figure 1-5 As shown, it includes: a fixed part 1 and multiple extension parts, wherein the fixed part 1 is fixedly connected to the valve nozzle and communicated with the inside of the valve nozzle. Multiple extension parts are arranged on the fixed part 1, and the multiple extension parts are all communicated with the inside of the fixed part 1. The multiple extension parts include an inflation part 2 and a charging part 3, the inflation part 2 is provided with an airway 21, and the airway 21 is communicated with the valve nozzle, and the charging part 3 is provided with a cable channel 31, and the cable channel 31 is communicated with the valve nozzle. The charging part 3 also includes a wire airtight structure 32, and the wire airtight structure 32 is arranged at one end of the charging part 3 away from the fixed part 1. A charging wire 33 is arranged in the cable channel 31, and the charging wire 33 passes through the wire airtight structure 32 and extends into the smart tire.

[0030] The valve auxiliary device is fixedly connected to the valve of the smart tire through the fixing part 1. The inner wall of the fixing part 1 is provided with a thread matching the outer wall of the valve, and the valve auxiliary device and the valve can be disassembled and assembled through the threaded connection, and the use process is simple and convenient.

[0031] The valve auxiliary device may include multiple branches, that is, a fixed portion 1 and multiple extension portions. The fixed portion 1 is arranged at one end of the valve auxiliary device, and the multiple extension portions are arranged concentrically with the fixed portion 1 or at a certain angle. The multiple extension portions are all provided with passages and outlets on the valve auxiliary device. The multiple extension portions are connected to the airway 21 or pipeline of the fixed portion 1 inside the valve auxiliary device. The fixed portion 1 and the multiple extension portions can be manufactured by integral molding, or by welding, bonding and other processes.

[0032] Among them, the multiple extension parts may include an inflation part 2 and a charging part 3. The inflation part 2 is used to inflate and deflate the smart tire to maintain tire pressure. There is no air duct 21 in the inflation part 2, and the air duct 21 is connected to the inside of the fixing part 1. The end of the air duct 21 is an air inlet, and the inflation part 2 can be directly connected to an external air source at the air inlet, and the external air source inflates the tire through the air duct 21 of the inflation part 2. During the inflation process, the gas enters the air duct 21 through the air inlet, then enters the fixing part 1 along the air duct 21, and finally enters the tire through the tire valve to achieve the purpose of inflation.

[0033] Similarly, when the tire needs to be deflated, the gas in the tire can flow from the valve stem through the fixing portion 1 into the air passage 21 and then flow out from the air inlet to achieve the purpose of deflation. The present application can perform inflation and deflation operations according to actual needs without changing the tire valve stem structure, and the operation is simple.

[0034] The charging unit 3 is used to supply power to the sensor chip and other components in the smart tire. The charging wire 33 in the charging unit 3 enters the tire through the valve and is connected to the sensor chip and other components. When charging is needed, the charging unit 3 is connected to an external power source to directly charge the sensor chip and other components in the smart tire. After charging is completed, the charging unit 3 is disconnected from the external power source. During the charging process, there is no need to disassemble the tire to replace the battery. It can be charged as needed, which is very convenient to use. Using an external power source to charge the sensor chip and other components in the smart tire does not require an auxiliary friction power generation device to be installed inside the tire. It also solves the problem that the auxiliary friction power generation device inside the tire has a small power generation capacity and cannot meet the power supply needs of components such as sensor chips.

[0035] A wire airtight structure 32 is also provided on the charging part 3, and the wire airtight structure 32 is provided at the end of the charging part 3 away from the fixing part 1, that is, the end of the charging part 3 connected to the external power supply. The wire airtight structure 32 is fixed in the cable channel 31 inside the charging part 3, and the wire airtight structure 32 can completely block the cable channel 31 so that the airtightness in the cable channel 31 meets the requirements. The charging wire 33 passes through the wire airtight structure 32, passes through the tire valve and extends to the inside of the tire. It can be understood that the contact between the charging wire 33 and the wire airtight structure 32 also maintains the airtightness requirements.

[0036] Compared with the prior art, the embodiment of the present application integrates the functions of tire inflation, deflation, and charging through the valve auxiliary device, and divides each into independent channels. The charging wire 33 can extend to the inside of the smart tire through an independent cable channel 31, and directly charge the sensors inside the tire, etc., without changing the valve structure, and will not affect the overall performance of the rim and the wheel. It not only ensures the normal ventilation and air retention functions of the valve, but also transmits external electrical energy to the internal sensor of the tire to ensure the power supply requirements of the sensor chip. The valve auxiliary device provided by the present application can realize the conduction and inflation and deflation operations at the same time without destroying the existing whole wheel hub. It can not only ensure the energy required for the sensor to collect signals and transmit data, but also realize tire inflation and deflation to ensure the normal operation of the entire smart tire. It solves the technical problems in the prior art that the smart tire cannot be powered continuously for a long time, the battery replacement process is cumbersome, and the internal power generation is insufficient, and the power supply requirements of the sensor chip cannot be guaranteed.

[0037] The embodiment of the present application can realize internal power supply of the sensor array without affecting the air retention performance of the valve. The number of the multiple extensions can be multiple, and the multiple extensions can be set according to the internal power supply requirements of the smart tire. Preferably, the number of extensions does not exceed five. In this embodiment, one extension of the valve auxiliary device is used for inflation and deflation, and the other extension is connected with a wire for external power supply to the internal electronic components. On the basis of not changing the existing overall structure, it not only ensures the air retention of the combination of the valve and the wire, but also can be independently inflated and deflated.

[0038] The embodiment of the present application can meet the requirements of both full-steel and semi-steel valves, and can be used on full-steel or semi-steel valves.

[0039] In one embodiment, the wire airtight structure 32 is provided with a wire passing hole 321 , and the charging wire 33 is passed through the wire passing hole 321 and penetrates the wire airtight structure 32 .

[0040] In order to ensure that the wire airtight structure 32 has good airtightness, the charging wire 33 is provided with a wire hole 321 of a size matching the wire on the wire airtight structure 32. It can be understood that the number of the wire holes 321 is the same as that of the charging wire 33. In one example, a sealing pad can be provided at the edge of the wire hole 321 to further improve the airtightness between the charging wire 33 and the wire airtight structure 32. The provision of the sealing pad also reduces the probability of friction damage of the charging wire 33, and the airway 21 protects the cable.

[0041] In one embodiment, the wire airtight structure 32 includes: a wire airtight layer 322 fixed to the inner wall of the cable channel 31 and away from the fixing portion 1. The wire through hole 321 is provided on the wire airtight layer 322.

[0042] The wire airtight layer 322 is arranged in the cable channel 31, and its outer edge is in contact with the cable channel 31, completely blocking the cable channel 31. The wire airtight layer 322 can be made of silicone, rubber, plastic and other similar materials, and the thickness of the wire airtight layer 322 can be set according to requirements. After the wire airtight layer 322 is installed, it forms a structure with good airtightness with the wall of the cable channel 31. In one example, the wire airtight layer 322 can be provided with a wire hole 321 according to the insertion position of the charging wire 33, and the size of the wire hole 321 can match or fit the charging wire 33 to keep the airtightness within the allowable range.

[0043] In one embodiment, the wire airtight structure 32 further includes: a locking screw plug 232 fixed to one end of the cable channel 31 , and the locking screw plug 232 is threadedly connected to the cable channel 31 .

[0044] Specifically, in this embodiment, an internal thread is provided in the cable channel 31 of the charging unit 3, and the internal thread can cover the entire cable channel 31. Preferably, the internal thread can be provided on the wall of a section of the cable channel 31 from the end of the cable channel 31 to the wire airtight layer 322.

[0045] The locking screw plug 232 has a cylindrical plug body 3232, the outer diameter of which matches the inner diameter of the cable channel 31. An outer thread is provided on the outer wall of the plug body 3232, which matches the inner thread to achieve threaded connection between the locking screw plug 232 and the cable channel 31.

[0046] In one embodiment, the locking screw plug 232 further includes a sealing plate 3231 , which is fixed to one end of the plug body 3232 . The sealing plate 3231 covers the cable channel 31 .

[0047] The plug body 3232 may be a circular tube, and a sealing plate 3231 is fixed at one end of the plug body 3232. The sealing plate 3231 and the plug body 3232 may be integrally formed or fixed by welding. In one example, the sealing plate 3231 is a circular plate, and the diameter of the sealing plate 3231 is larger than the outer diameter of the plug body 3232. The sealing plate 3231 abuts against the end of the cable channel 31 to ensure the sealing of the two.

[0048] In one embodiment, the outer diameter of the charging part 3 is cylindrical, and the diameter of the sealing plate 3231 is the same as the outer diameter of the charging part 3. This embodiment allows the external structure of the charging part 3 to be consistent with the external structure of the locking screw plug 232 when the locking screw plug 232 is fixed on the charging part 3, avoiding interference with other extension parts, and having a neat and beautiful appearance.

[0049] In one embodiment, a charging connector is provided on the sealing plate 3231, and the contact of the charging connector is located in the cable channel 31, and the charging wire 33 is electrically connected to the contact. The charging connector can be detachably connected to an external power source to facilitate power access. After the sealing plate 3231 is fixed to the cable channel 31, the cable channel 31 is sealed, and the charging wire 33 is connected to the surface of the sealing plate 3231 facing the cable channel 31, on which the contact of the charging connector is provided, and the charging wire 33 is electrically connected to the contact of the charging connector.

[0050] The charging connector and the sealing plate 3231 are sealed, and the sealing can be achieved by a sealing rubber pad or by bonding. After the locking screw plug 232 is fixed to the cable channel 31, the sealing between the cable channel 31 and the outside world can be ensured. When the user uses the valve auxiliary device to inflate the tire, the tire can be inflated normally and the gas will not leak from the cable channel 31.

[0051] In one embodiment, after the locking screw plug 232 is fixedly connected to the cable channel 31, the locking screw plug 232 abuts against the wire airtight layer 322. That is, the length of the locking screw plug 232 extending into the cable channel 31 is equal to the distance between the wire airtight layer 322 and the end of the cable channel 31. In this embodiment, a cavity is formed between the plug body 3232 of the locking screw plug 232 and the wire airtight layer 322 of the wire airtight structure 32, and the charging wire 33 is inserted into the cavity. The abutment between the locking screw plug 232 and the wire airtight layer 322 can enhance the strength of the wire airtight structure 32. When the tire is inflated, the wire airtight structure 32 is rigidly connected to the locking screw plug 232, which can block the impact of the high-pressure gas entering the valve auxiliary device on the wire airtight structure 32, and prevent the wire airtight layer 322 from being pushed out by the high-pressure gas, resulting in gas leakage. The cavity formed between the plug body 3232 of the tightening screw plug and the wire airtight layer 322 can also protect the connection between the charging wire 33 and the charging connector contact, preventing high-pressure gas from impacting the charging wire 33 and the charging connector contact, causing power outage.

[0052] In one embodiment, a sealing nut is provided at the end of the inflatable part 2, and the sealing nut is threadedly connected to the inflatable part 2. After the tire is inflated, the sealing nut can be used to seal the inflatable part 2 to prevent air leakage. In this embodiment, the outer wall of the inflatable part 2 is provided with a thread, and the inner wall of the sealing nut is provided with a thread matching the thread of the outer wall of the inflatable part 2. The sealing nut is threadedly connected to the inflatable part 2, and the connected sealing nut blocks the end of the inflatable part 2, so that the inflatable part 2 achieves a good sealing effect.

[0053] In other embodiments, the inflatable part 2 may be sealed by using a pluggable sealing plug, a sealing gasket, etc., as long as the sealing requirements are met.

[0054] In one embodiment, a sealing ring may be provided at the connection between the sealing nut and the end of the inflatable part 2 to improve the airtightness of the connection between the sealing nut and the inflatable part 2. The sealing ring may be made of a rubber material, which has a certain plasticity and improves the sealing effect.

[0055] In one embodiment, the air valve auxiliary device further includes: a sealing gasket, which is arranged between the fixing portion 1 and the air valve.

[0056] Specifically, in this embodiment, the valve auxiliary device may further provide a sealing gasket between the fixing portion 1 and the valve to improve the air tightness between the valve and the fixing portion 1 .

[0057] The fixing part 1 is provided with an interface matching the valve nozzle, and the fixing part 1 is connected to the valve nozzle through the interface. The interface and the valve nozzle can be set to a detachable connection structure, for example, a threaded connection, a quick plug-in connection, a snap-on connection, etc. In certain special environments, the interface and the valve nozzle can also be set to a non-detachable connection method, such as welding, bonding, etc. It can be set according to actual conditions. In this embodiment, the interface and the valve nozzle are preferably detachably connected.

[0058] The interface of the fixing part 1 can be wrapped around the periphery of the valve, the outer wall of the valve and the inner wall of the fixing part 1 can be provided with matching threads, and the fixing part 1 can be detachably fixed on the valve. The channel in the fixing part 1 is connected with the valve, and the high-pressure gas can enter the valve through the channel in the fixing part 1 to inflate the tire.

[0059] In one embodiment, the plurality of extension portions further include: a communication portion, provided with a communication cable channel, and the communication cable channel is connected to the valve nozzle.

[0060] Specifically, in this embodiment, the number of extension parts can be determined according to demand, and in addition to the above-mentioned inflation part 2 and charging part 3, extension parts such as a communication part can also be provided. Communication cables are arranged inside the communication part to realize signal transmission between the sensor in the smart tire and the outside.

[0061] A communication channel is provided inside the communication part, and the communication channel is connected to the interior of the fixing part 1. A communication cable is passed through the communication channel, and the communication cable extends through the valve nozzle to the sensor (or other components) inside the tire. A sealing structure such as a sealing cover can also be provided at the end of the communication part to ensure the airtightness of the auxiliary device.

[0062] The embodiment of the present application can integrate the functions of tire inflation, deflation, and charging through the valve auxiliary device, and divide them into independent channels. The charging wire 33 can extend to the inside of the smart tire through an independent cable channel 31, and directly charge the sensors inside the tire, etc., without changing the valve structure, and will not affect the overall performance of the rim and the wheel. It can not only ensure the normal ventilation and air retention functions of the valve, but also transmit external electrical energy to the internal sensors of the tire to ensure the power supply requirements of the sensor chip. The valve auxiliary device provided in the present application can realize the conduction and inflation and deflation operations at the same time without destroying the existing whole wheel hub. It can not only ensure the energy required for the sensor to collect signals and transmit data, but also realize tire inflation and deflation, ensuring the normal operation of the entire smart tire.

[0063] In order to meet the requirements of inflation and deflation and external power supply, the embodiment of the present application adopts a branch structure similar to a tree branch, which facilitates the wire to pass into the tire, avoids damaging the rim and the valve, and is convenient for disassembly and assembly.
