[0002] A tire pressure gauge is a portable instrument specifically designed to measure the air pressure inside vehicle tires. It is an essential tool for the routine maintenance and safety checks of vehicles such as cars, motorcycles, and bicycles, directly impacting driving safety, tire life, and fuel economy.

[0003] A brake fluid tester (also known as a brake oil detector) is a specialized diagnostic tool that uses electrical conductivity to quickly and quantitatively detect the water content of brake fluid in a hydraulic braking system.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

The tire pressure sensor 21 is electrically connected to the electronic control assembly 1. The probe assembly 22 includes a tire pressure probe section 221, an air tube section 222, and an air cover section 223 connected in sequence.

The tire pressure probe section 221 is connected to the sealed cavity through the air tube section 222. The tire pressure probe section 221 is configured to connect to the tire valve. The specific structure of the tire pressure probe section 221 can use existing designs.

[0064] Explained, the gas cover 223 can be sealed to the electronic control component 1 using sealant to form a sealed cavity. Alternatively, in some embodiments, the gas cover 223 is connected to the electronic control component 1 using fastening bolts, and a sealing ring can be sandwiched between the gas cover 223 and the electronic control component 1 to achieve a sealed connection and form a sealed cavity. Specifically, the gas cover 223 can be connected to the circuit board 11 of the electronic control component 1.

[0065] refer to Figure 1-5 In some embodiments, the brake fluid measuring assembly 3 includes a brake fluid probe 31. The brake fluid probe 31 is electrically connected to the electronic control assembly 1 via a measuring adapter cable 32, and is configured to contact the brake fluid to be tested. In use, the brake fluid detection is activated, and then the brake fluid probe 31 is immersed in the brake fluid for 15 seconds. The result is read through the display screen 4. The brake fluid probe 31 determines the condition of the brake fluid by detecting its water content; any existing technology can be used, and no specific limitation is made. The specific structure of the brake fluid probe 31 can use any existing technology.

The brake fluid calibration box 5 has a probe socket 51, configured to insert a brake fluid probe 31 for brake fluid detection and calibration measurement. When brake fluid monitoring and calibration are required, the brake fluid probe 31 is inserted into the probe socket 51, and then the brake fluid detection and calibration is initiated. The brake fluid calibration box 5 can use an existing resistor box, and the specific calibration method and procedure can use existing solutions; no specific limitations are imposed. The improvement of this application's implementation lies in integrating the brake fluid calibration box 5 and the brake fluid calibration function.

It features high integration and multiple functions, combining tire pressure monitoring and brake fluid detection. Compared to purchasing tire pressure gauges and brake fluid testers separately, the integrated design is more cost-effective.

[0068] refer to Figure 1-5 In some embodiments, the housing 6 has a plug-in groove 61, and the brake fluid calibration box 5 can be detachably plugged into the plug-in groove 61. The separate and detachable design structure facilitates the individual replacement and maintenance of the brake fluid calibration box 5.

[0069] refer to Figure 1-5 In some embodiments, the brake fluid measuring assembly 3 further includes a protective sleeve 33, which is sleeved on the measuring adapter cable 32 and can protect the measuring adapter cable 32.

[0070] In some implementations, reference Figure 1-5 The housing 6 is a handheld housing, which improves portability. Furthermore, in some embodiments, the housing 6 may include a first housing, a second housing, a first tailstock, and a second tailstock. The first housing, the second housing, the first tailstock, and the second tailstock are combined together to carry the electronic control component 1, the tire pressure sensing component 2, the brake fluid measuring component 3, the display screen 4, and the brake fluid calibration box 5. The housing 6 has a split design, which facilitates the assembly and integration of various components.

[0071] refer to Figure 1-5In some embodiments, the electronic control assembly 1 includes a circuit board 11 disposed within the housing 6, which is electrically connected to the tire pressure sensor 21, the brake fluid probe 31, and the display screen 4. The tire pressure sensor assembly 2 includes a tire pressure probe 221 configured to connect to the tire valve. A measuring adapter cable 32 extends from a first end of the housing 6, and the tire pressure probe 221 extends from a second end of the housing 6, the second end being the end of the housing 6 opposite to the first end. By arranging the tire pressure probe 221 and the measuring adapter cable 32 at both ends of the housing 6, interference between the tire pressure probe 221 and the brake fluid probe 31 is reduced.

[0072] The integrated tire pressure and brake fluid tester provided in some embodiments of this application, when applied to vehicle tire pressure and other testing, can have the following advantages:

[0073] 1. A single device can simultaneously monitor tire pressure and brake fluid water content, achieving dual functions of tire pressure detection (tire safety) and brake fluid detection (brake safety), covering core vehicle safety dimensions;

[0074] 2.
