Description

Technical Field

[0001] This utility model belongs to the field of automotive electronics technology, and relates to a tire pressure regulating device, a tire pressure sensor, and a vehicle. Background Technology

[0002] Currently, tire pressure sensors are primarily built into the tire to monitor the internal pressure and transmit the detected pressure to the vehicle's infotainment system. The system then displays the tire pressure on the instrument panel. When the tire pressure is too high, the driver needs to stop the vehicle and manually unscrew the dust cap on the sensor and release the air by adjusting the valve stem on the valve stem to maintain the tire pressure within the appropriate range. Some solutions involve additional pressure control devices, pressure sensors, pipes, and wiring located on the wheel rim or around the tire. Tire pressure is adjusted using this additional device. These components on the wheel rim and around the tire not only affect the vehicle's appearance but also significantly increase operating costs. The added external components and piping also increase driving safety risks, making it difficult to achieve practical commercial applications. Utility Model Content

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0044] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0045] This invention provides a tire pressure regulating device, including a valve core assembly and an electronic component disposed inside a tire pressure sensor. The valve core assembly includes a valve stem and a magnetic component disposed within the valve stem. The electronic component inside the tire pressure sensor includes an electromagnetic induction device, a driver, and a processing circuit. The processing circuit is electrically connected to the driver, and the processing circuit drives the electromagnetic induction device to generate magnetic force, attracting the magnetic component to move towards the electromagnetic induction device, thereby opening the valve stem to release air.

[0047] In this application, the core rod of the magnetic material can be called a magnetic core rod, the core seat of the magnetic material can be called a magnetic core seat, and the core spring of the magnetic material can be called a magnetic core spring.

[0048] In one embodiment of this application, the magnetic component is a core rod made of a single magnetic material, and the driver is a driving circuit. The structure of the driving circuit will be described in detail in the following description.

[0049] Specifically, please refer to Figure 1This utility model provides a tire pressure regulating device, including a valve core assembly 10 and an electronic component 20. The valve core assembly 10 includes a valve stem 13, a core spring 14 disposed within the valve stem 13, and a magnetic core rod 15; the magnetic core rod 15 is kinetically connected to the core spring 14. The electronic component 20 includes an electromagnetic induction device 21, a drive circuit 22, and a processing circuit 23; the processing circuit 23 is electrically connected to the drive circuit 22, and the processing circuit 23 drives the electromagnetic induction device 21 to generate magnetic force, attracting the magnetic core rod 15 to move towards the electromagnetic induction device, thereby compressing the core spring 14 and causing the valve stem of the valve stem to open and release air.

[0050] In one embodiment of this application, as Figure 2A As shown, it provides an exemplary structural schematic diagram of a valve core assembly 10, which includes a valve stem (not shown), a core spring 14, a magnetic core rod 15, a core seat 16, a core seat sealing gasket 16a, a core spring support 17, a dust cap (core cap) 18, a core body 19, and a core body sealing ring 19a. The core spring 14, the magnetic core rod 15, the core seat 16, and the core spring support 17 are disposed inside the valve stem, with the core spring 14 positioned between the core seat 16 and the core spring support 17. The core spring support 17 has a through hole through which the magnetic core rod 15 passes. The core spring 14 is kinetically connected to the magnetic core rod 15, and the core seat 16 is fixedly connected to the magnetic core rod 15. The valve stem 13 is the air passage for tire inflation and deflation. When the core spring 14 is not compressed, it seals the valve stem. When the magnetic core rod 5 moves toward the electromagnetic induction device, it compresses the core spring 14, causing the valve stem of the valve stem to open and automatically deflate the tire.

[0051] In one embodiment of this application, when the magnetic core rod 15 moves toward the electromagnetic induction device 21 through the through hole on the core spring support 17, it drives the core seat 16 to move, causing the core seat 16 to compress the core spring 14, thereby opening the valve of the valve rod and releasing air from the tire.

[0052] In one embodiment of this application, the magnetic core rod 15 can also be fixedly connected to one end of the core spring 14. When the magnetic core rod 15 moves toward the electromagnetic induction device 21 through the through hole on the core spring support 17, the magnetic core rod 15 directly drives the core spring 14 to compress and release the air from the tire.

[0053] In one embodiment of this application, as Figure 2BAs shown, a schematic diagram of an exemplary specific structure of a valve core assembly 10 is provided. The valve core assembly 10 includes a valve stem (not shown), a core spring 14, a magnetic core rod 15, a core seat 16, a core seat sealing gasket 16a, a dust cap (core cap) 18, a core body 19, and a core body sealing ring 19a. The core spring 14, magnetic core rod 15, core seat 16, core seat sealing gasket 16a, core body 19, and core body sealing ring 19a are disposed within the valve stem, and the core spring 14 is disposed between the core seat 16 and the core spring support 17. The core seat 16 has a through hole through which the magnetic core rod 15 passes. The core spring 14 is kinetically connected to the magnetic core rod 15. When the magnetic core rod 15 moves toward the electromagnetic induction device, it compresses the core spring 14, causing the valve stem of the valve stem to open, thus automatically deflating the tire.

[0054] In one embodiment of this application, the valve core assembly 10 in this embodiment can be specifically based on, for example: Figure 2A and Figure 2B The valve core structure shown can be improved, or it can be based on other types of valve cores to improve the design according to the principles of this application. Alternatively, it can be customized according to the structural description of the valve core assembly in this application. To achieve effective cooperation between the electromagnetic induction device (e.g., a coil) and the magnetic core rod 15, and to ensure sufficient attraction during operation, the length of the magnetic core rod 15 can be increased. In this embodiment, the principle of electromagnetism is used. During venting, the magnetic force generated pulls the magnetic core rod 15 to compress the core spring 14, causing the valve stem to open and release air.

[0055] In one embodiment of this application, the valve core assembly 10 is disposed on the tire, with one end communicating with the inner side of the tire, and the other end located outside the tire connected to a dust cap 18. The valve core assembly is fixed on the vehicle wheel hub, and the electronic component 2 is installed in the vehicle tire.

[0056] In one embodiment of this application, as Figure 3 As shown, the electronic component 20 includes an electromagnetic induction device 21, a driving circuit 22, and a processing circuit 23. The processing circuit 23 is electrically connected to the driving circuit 22. The processing circuit 23 drives the electromagnetic induction device 21 to generate magnetic force through the driving circuit 22, attracting the magnetic core rod 15 to move towards the electromagnetic induction device 21, thereby driving the core spring 14 to compress and open the valve of the valve rod to release air.

[0057] In one embodiment of this application, the electromagnetic induction device 21 includes an electromagnet or a coil. The processing circuit 23 drives the electromagnet or coil to generate magnetic force through the driving circuit 22, thereby attracting the magnetic core rod 15 to move towards the electromagnet or coil, driving the core spring 14 to compress, so that the valve of the valve rod opens to deflate the tire.

[0058] It should be noted that when only one type of magnetic material is used in the component, such as the magnetic core rod 15 in the above embodiment, or a single magnetic core spring or magnetic core seat in other embodiments, a permanent magnet material can be used in the application. The magnetic force can be controlled by controlling the distance of the permanent magnet material, so as to achieve the purpose of venting by pulling the core spring with magnetic force.

[0059] It should be noted that in the above embodiment, the core rod is made of a magnetic material. In other variations, the core spring, core seat, and other components inside the valve core can also be made of magnetic materials to achieve the same exhaust purpose.

[0060] In one embodiment of this application, when the core rod is made of magnetic material, the core rod (i.e., the magnetic core rod) moves through the through hole towards the electromagnetic induction device under the action of magnetic attraction, causing the core seat to move and compress the core spring, thereby opening the valve of the valve rod to release air.

[0061] In one embodiment of this application, when the core seat is made of magnetic material, the core seat (i.e., the magnetic core seat) moves towards the electromagnetic induction device under the action of magnetic attraction, causing the core rod to pass through the through hole and compress the core spring, thereby opening the valve of the valve rod to release air. In this application, the core seat made of magnetic material can be referred to as a magnetic core seat.

[0062] In one embodiment of this application, when the core spring is made of magnetic material, when the core spring (i.e., magnetic core spring) moves towards the electromagnetic induction device under the action of magnetic attraction, it drives the core rod to pass through the through hole and simultaneously drives the core seat to move, causing the valve of the valve rod to open and release air. In this application, the core spring made of magnetic material can be referred to as a magnetic core spring.

[0063] Furthermore, in other embodiments, any two or more components among the core rod, core spring, and core seat can be made of magnetic materials. Since the principle of venting is similar to that in the above embodiments, it will not be described in detail here.

[0064] Furthermore, in one embodiment of this application, as Figure 3As shown, the electronic component 20 also includes a Bluetooth communication module 24, a temperature sensor 25, an acceleration sensor 26, a pressure sensor 27, and / or a crystal oscillator 28. The Bluetooth communication module 24 is electrically connected to the processing circuit 23 for Bluetooth communication with external devices. The temperature sensor 25 is electrically connected to the processing circuit 23 to monitor the tire's internal temperature. The acceleration sensor 26 is electrically connected to the processing circuit 23 to monitor the tire's acceleration. The pressure sensor 27 is electrically connected to the processing circuit 23 to monitor the tire's internal pressure. The crystal oscillator 28 is electrically connected to the processing circuit 23 to provide an operating clock for the processing circuit. The Bluetooth communication module, electrically connected to the processing circuit, is used for Bluetooth communication with external devices. The transmitted data may include tire internal temperature, tire acceleration, tire pressure, and Bluetooth control commands issued by the vehicle control terminal. The temperature sensor monitors the tire's internal temperature, the acceleration sensor monitors the tire's acceleration, the pressure sensor monitors the tire's internal pressure, and the crystal oscillator provides an operating clock for the processing circuit.

[0065] Furthermore, in one embodiment of this application, as Figure 3 As shown, the electronic component 20 includes an electromagnetic induction device 21, a drive circuit 22, a processing circuit 23, a Bluetooth communication module 24, a temperature sensor 25, an acceleration sensor 26, a pressure sensor 27, and a crystal oscillator 28. It may also include a battery 29 and a low-frequency circuit (not shown). The battery 29 is used to provide power, and the low-frequency circuit can be used for external factory matching and teaching.

[0066] In one embodiment of this utility model, as Figure 4 As shown, the driving circuit 22 includes an optocoupler 221 and a transistor 222. The optocoupler 221 converts the voltage provided by the processing circuit 23 into an output voltage. The transistor 222 is electrically connected to the output terminal of the optocoupler 221, converting the output voltage into current and providing it to the electromagnetic induction device 21, causing the electromagnetic induction device 21 to generate magnetic force.

[0067] It should be noted that, as Figure 4In the illustrated embodiment, the driving circuit 22 includes, in addition to the optocoupler 221 and the transistor 222, a protection resistor, specifically a first resistor R1, a second resistor R2, and a third resistor R3. The input-side cathode of the optocoupler P is electrically connected to the output port of the processing circuit, the output-side collector of the optocoupler P is electrically connected to the base of the transistor Q, and the collector of the transistor Q is electrically connected to the electromagnetic induction device. The input-side anode of the optocoupler P is connected to the positive terminal of the power supply through the first resistor R1, the output-side emitter of the optocoupler P is connected to the positive terminal of the power supply, the output-side collector of the optocoupler P is grounded through the second resistor R2, the output-side collector of the optocoupler P is electrically connected to the base of the transistor Q through the third resistor R3, the emitter of the transistor Q is grounded, and one side of the electromagnetic induction device is connected to the positive terminal of the power supply. The processing circuit is electrically connected to the driving circuit through the IO port. When the driving circuit is working, the IO port generates a high level, the optocoupler is turned on, the base of the transistor generates a high level, and after the transistor is turned on, the coil is energized and generates magnetic force.

[0068] In one embodiment of this application, the processing circuit can provide a suitable operating voltage to the driving circuit, enabling the driving circuit to work normally or stop working. The processing circuit described in this embodiment can be implemented by existing circuits, existing MCUs, or dedicated integrated chips. The specific structure of the processing circuit is not an improvement of this utility model and can be implemented by existing technology.

[0069] In other embodiments of this application, a dedicated driver chip (hereinafter referred to as driver chip) may be used to replace the driver circuit in the above embodiments in order to achieve the purpose of driving the electromagnetic induction device to generate magnetic force.

[0070] like Figure 5A As shown, this utility model also provides a tire pressure sensor 60, which is magnetically connected to a magnetic component in the valve core assembly. The tire pressure sensor 60 includes an electromagnetic induction device 61, a driver 62, and a processing circuit 63. The processing circuit 63 is electrically connected to the driver 63. The processing circuit 63 drives the electromagnetic induction device 61 to generate magnetic force through the driver 62, attracting the magnetic component in the valve core assembly to move towards the electromagnetic induction device, thereby compressing the core spring in the valve core assembly to release air. The driver 62 includes a driving circuit or a driving chip in application. The magnetic component in the valve core assembly can be any internal structure of the valve core assembly, such as a magnetic core rod, a magnetic core spring, and / or a magnetic core seat. The scope of protection of this application is not limited to the specific structure or composition of the magnetic component. Any magnetic component inside the valve core assembly implemented according to the principles of this application combined with the structural design of existing technology is included within the scope of protection of this application.

[0071] In one embodiment of this application, as Figure 5B As shown, the tire pressure sensor 60 may further include a Bluetooth communication module 64, a temperature sensor 65, an acceleration sensor 66, a pressure sensor 67, and / or a crystal oscillator 68. The Bluetooth communication module 64 is electrically connected to the processing circuit 63 for Bluetooth communication with external devices. The temperature sensor 65 is electrically connected to the processing circuit 63 to monitor the temperature inside the tire. The acceleration sensor 66 is electrically connected to the processing circuit 63 to monitor the acceleration of the tire. The pressure sensor 67 is electrically connected to the processing circuit 63 to monitor the pressure inside the tire. The crystal oscillator 68 is electrically connected to the processing circuit 63 to provide an operating clock for the processing circuit.

[0072] For example, based on the hardware structure of the tire pressure sensor or tire pressure regulating device described in this application, software control functions can be further added to achieve the following working process: The tire pressure sensor can periodically monitor the pressure inside the tire through a processing circuit (or MCU) and send the real-time tire pressure value to the vehicle control device (or in-vehicle control device) via a Bluetooth communication module. When the vehicle control device receives the tire pressure value and determines that the tire pressure is in an abnormal range, the vehicle control device sends a deflation command to the corresponding tire pressure sensor via BLE (Bluetooth Low Energy) to the corresponding tire pressure sensor. After receiving this command, the corresponding tire pressure sensor enters a fast pressure sampling mode and drives an optocoupler through an I / O port. The optocoupler connects to a transistor that conducts, and the coil generates magnetic force through current. The magnetic force attracts the magnetic component (such as the core rod) in the valve stem to move towards the coil end. The movement of the core rod will cause the core spring to compress, thereby causing the gas inside the tire to be discharged to the outside of the tire through the valve stem. Simultaneously, the pressure sensor inside the tire pressure sensor collects the internal tire pressure in real time after deflation until the pressure returns to the normal range. Then, the MCU (Microcontroller Unit) disconnects the optocoupler via the I / O port, the coil stops receiving power, the magnetism disappears, the spring returns to its original position, the air passage is sealed, deflation stops, and the system exits the fast pressure sampling mode. At the same time, the MCU sends the current tire pressure to the vehicle control equipment via BLE. Specifically, when the drive circuit is working, the I / O port generates a high level, the optocoupler conducts, the transistor base generates a high level, and after the transistor conducts, the coil is energized, generating magnetism.

[0073] It should be noted that the description of the tire pressure sensor in this embodiment has been described in detail in the electronic components section of the above embodiments, and will not be repeated in this embodiment.

[0074] like Figure 6As shown, this utility model also provides a vehicle 70, including wheels 71, an on-board control device 72 and / or an on-board display 73. The wheels 71 have a built-in tire pressure regulating device as described above; the on-board control device 72 is communicatively connected to the tire pressure regulating device; the on-board display 73 is communicatively connected to the on-board control device 72.

[0075] In one embodiment of this application, the vehicle control device 72 is connected to the tire pressure regulating device via Bluetooth communication.

[0076] It should be noted that the tire pressure regulating device in the above embodiments is applied to the vehicle tire. Therefore, this embodiment provides a vehicle in which the tires may be specifically provided with any of the above-mentioned tire pressure regulating devices. The vehicle also includes an on-board control device, such as an on-board terminal, which is communicatively connected to the tire pressure regulating device, and an on-board display, such as a vehicle infotainment display screen, which is communicatively connected to the on-board control device to display data such as tire temperature, pressure, and acceleration.
