Description

Technical Field

[0001] This utility model relates to the technical field of automotive tire pressure monitoring and inflation equipment, and in particular to an integrated automotive tire pressure monitoring and inflation device. Background Technology

[0002] Accurate tire pressure directly affects driving safety and tire lifespan. Vehicle owners and maintenance personnel often need to regularly check and inflate tires. Currently, tire pressure monitoring typically involves operators checking and inflating each tire individually until the tire pressure across the vehicle is consistent. This method requires operators to memorize and interpret data, resulting in low efficiency and susceptibility to human error, leading to inaccurate measurements, underinflation, or overinflation. Furthermore, it cannot simultaneously monitor and compare the tire pressure of two tires on the same axle in real time, nor can it quickly adjust the pressure of two tires to the same value. Based on these issues, we propose an integrated tire pressure monitoring and inflation device to address these problems. Utility Model Content

[0003] This invention provides an integrated device for automotive tire pressure monitoring and inflation to solve the problems in the prior art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] An integrated tire pressure monitoring and inflation device for automobiles includes an inflation component, an air supply line, a pressure sensor, a display unit, and a controller. The inflation component is used to inflate the tire with gas. The air supply line includes a first air passage and a second air passage, which are connected to the output end of the inflation component via an air passage control mechanism and are respectively connected to a first valve connector and a second valve connector for connecting to the tire. The pressure sensor is located on the first and second air passages to detect the gas pressure in the first and second air passages. The display unit is located on the main unit to display the pressure values ​​of the first and second air passages monitored by the pressure sensor. The controller activates and deactivates the air passage control mechanism to inflate the first and second air passages according to the pressure signal from the pressure sensor.

[0006] Preferably, both the first and second air lines are equipped with venting lines and venting valves, and the venting valves are electrically connected to the controller; when the pressure sensor detects that the tire pressure exceeds a preset value, the controller opens the corresponding venting valve to vent the tire.

[0007] Preferably, it also includes a status indicator light group, which includes at least three colors of indicator lights. When the tire is inflated, the first color indicator light is lit; when the tire is deflated, the second color indicator light is lit; and when the tire pressure reaches a set value, the third color indicator light is lit.

[0008] Preferably, the controller is further configured with a tire pressure preset module, which is used to input the target tire pressure value corresponding to different vehicle models to set the preset range.

[0009] Preferably, both the first and second air passages adopt an anti-winding spiral design and are coated with a wear-resistant coating.

[0010] Preferably, the inflation component uses a variable frequency air pump, which can automatically adjust the inflation rate according to the tire pressure difference.

[0011] The beneficial effects of this utility model are: the dual air circuit design can connect two tires on the same axle at the same time. With the pressure sensor, there is no need to repeatedly replace the tire pressure gauge and air pump, nor is it necessary for the operator to actively record the tire pressure data. It can directly compare the tire pressure difference and add air, thereby improving operating efficiency and reducing human error. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] Reference Figures 1-3 As shown, an integrated tire pressure monitoring and inflation device for automobiles includes an inflation component 1, an air supply line, a pressure sensor 5, a display unit 6, and a controller 7. The inflation component 1 is used to inflate the tire with gas. The air supply line includes a first air passage 2 and a second air passage 3, which are connected to the output end of the inflation component 1 via an air passage control mechanism 4. The end of the first air passage 2 furthest from the inflation component 1 is connected to a first valve connector 21 for connecting to the tire, and the end of the second air passage 3 furthest from the inflation component 1 is connected to a second valve connector 31 for connecting to the tire. The pressure sensor 5 is fixed to the first air passage 2 and the second air passage 3 respectively, and is used to detect the gas pressure in the first air passage 2 and the second air passage 3 in real time. The display unit 6 is embedded in the surface of the device's main unit, and is used to synchronously display the pressure values ​​of the first air passage 2 and the second air passage 3 monitored by the pressure sensor 5. The controller 7 is fixed inside the main unit and is connected to the inflation component 1, the pressure sensor 5, the display unit 6, and the air passage control mechanism 7. The mechanism 4 is electrically connected and can control the opening and closing of the air circuit control mechanism 4 according to the pressure signal transmitted by the pressure sensor 5, thereby realizing the inflation control of the first air circuit 2 and the second air circuit 3. The display unit 6 can use two screens to display the air pressure information of the two air circuits respectively. The pressure sensor 5 can be a miniature piezoelectric sensor, which is embedded in the pipe section near the air valve connector of the first air circuit 2 and the second air circuit 3 respectively. Its detection end is connected to the inside of the air circuit, and the signal output end is connected to the controller 7 through the wire. When working, the gas pressure in the air circuit will squeeze the piezoelectric element of the sensor, causing the element to generate a weak electrical signal corresponding to the pressure. After the electrical signal is amplified by the signal processing module inside the sensor, it is transmitted to the controller 7 in real time. The controller 7 then converts the electrical signal into an intuitive tire pressure value (such as Bar, PSI) and displays it on the display unit 6 simultaneously, thereby realizing the real-time and accurate detection of the tire pressure of both tires. The above is the prior art, which should be known to those skilled in the art, and will not be described in detail here.

[0019] The air circuit control mechanism 4 can be an electromagnetic reversing valve. Its input end is connected to the gas output end of the inflation component 1, and its two output ends are respectively connected to the first air circuit 2 and the second air circuit 3, and are electrically connected to the controller 7. For example, when in the left inflation mode, the controller 7 sends a signal to the electromagnetic reversing valve, so that it only opens the channel between the inflation component 1 and the first air circuit 2, and the gas only enters the left tire through the first air circuit 2. When in the right inflation mode, the electromagnetic reversing valve only opens the channel between the inflation component 1 and the second air circuit 3, and the gas only enters the right tire through the second air circuit 3. In the non-inflation state, the electromagnetic reversing valve closes the dual air circuit channels to avoid gas leakage, thereby realizing the switching control of dual air circuit inflation.

[0020] Reference Figures 1-3 As shown, both the first air passage 2 and the second air passage 3 are equipped with a venting pipe 8 and a venting valve 9. One end of the venting pipe 8 is connected to the corresponding air passage, and the other end extends to the outside of the main unit. The venting valve 9 is fixed on the venting pipe 8 and is electrically connected to the controller 7. When the pressure sensor 5 detects that the tire pressure of the corresponding tire exceeds the preset target tire pressure value in the controller 7, the controller 7 will immediately send an opening signal to the venting valve 9, causing the venting valve 9 to open. The air in the tire is then discharged through the venting pipe 8 until the pressure sensor 5 detects that the tire pressure has dropped to the preset value. At this point, the controller 7 controls the venting valve 9 to close, preventing the tire pressure from becoming too high.

[0021] Reference Figures 1-3 As shown, further, a status indicator light group 10 is also included. The status indicator light group 10 is installed on one side of the display unit 6 and electrically connected to the controller 7. The status indicator light group 10 includes indicator lights of at least three colors: a first color indicator light corresponding to the inflation state, a second color indicator light corresponding to the deflation state, and a third color indicator light corresponding to the tire pressure reaching the target value. Specifically, when the controller 7 controls the air circuit control mechanism 4 to open a certain air circuit for inflation, the first color indicator light (such as a red light) of the corresponding air circuit will remain lit; when the controller 7 controls the deflation valve 9 of a certain air circuit to open for deflation, the second color indicator light (such as a yellow light) of the corresponding air circuit will remain lit; when the pressure sensor 5 detects that the tire pressure of a certain air circuit has reached the preset target value, the third color indicator light (such as a green light) of the corresponding air circuit will light up to remind the user that the current tire pressure has reached the target value.

[0022] Reference Figures 2-3 As shown, the controller 7 is further equipped with a tire pressure preset module 11, which is electrically connected to the display unit 6, and the display unit 6 is a touch screen. Users can input target tire pressure values ​​corresponding to different vehicle models (such as sedans, SUVs, vans, etc.) into the tire pressure preset module 11 through the operation interface of the touch display unit 6, setting the preset range of tire pressure. The controller 7 will use the target tire pressure value set by the user as the basis for determining inflation and deflation, adapting to the tire pressure requirements of different vehicle models and improving the versatility of the equipment.

[0023] The first air passage 2 and the second air passage 3 are both made of rubber and have an overall anti-tangling spiral design. The outer surface of the air passage is also coated with a wear-resistant coating to prevent the air passage from getting tangled during storage or use. The wear-resistant coating can reduce friction loss between the air passage and the ground and the vehicle body, and extend the service life of the air passage.

[0024] The inflation component 1 uses a variable frequency air pump, which is electrically connected to the controller 7. The variable frequency air pump can receive signals from the controller 7 and automatically adjust the inflation rate according to the difference between the actual tire pressure detected by the pressure sensor 5 and the target tire pressure. When the difference is large, it inflates at a high rate to improve efficiency, and when the difference is small, it inflates at a low rate to ensure accuracy, thus avoiding tire pressure exceeding the standard due to fast inflation.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
