Description

Technical Field

[0001] This utility model relates to the field of automotive tire pressure testing, specifically an automotive tire pressure testing device. Background Technology

[0002] Tire pressure refers to the pressure of the air inside a tire. Its normal range is typically between 2.2 and 2.8 atmospheres. Specific values ​​need to be adjusted based on factors such as vehicle model, load, and temperature. Both excessively high and low tire pressure can negatively impact vehicle performance. Excessive tire pressure reduces the tire's contact patch, decreasing grip and increasing the risk of tire blowout and driving instability. Conversely, insufficient tire pressure exacerbates tire deformation, increasing rolling resistance and fuel consumption, while also shortening tire life.

[0003] During the maintenance of car tires, it is often necessary to use tire pressure testing equipment to check the tire pressure. However, current tire pressure testing equipment cannot perform pressure replenishment on the tested tires, thus affecting its usability. Utility Model Content

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figure 1-5 In this embodiment of the present invention, a tire pressure monitoring device includes a detection frame 1. Rolling components are provided at the four corners of the bottom of the detection frame 1 to facilitate movement of the device. A mounting bracket 5 is provided at the center of the top of the detection frame 1, and a tire pressure detector 6 is provided at the bottom of the mounting bracket 5. A first connecting pipe 7 is provided at the bottom of the tire pressure detector 6, and the bottom of the first connecting pipe 7 is connected to a tire sealing connector 9 via a first connecting hose 8. A tire clamping assembly is rotatably mounted at one end of the bottom of the detection frame 1, and a piston cylinder 14 is fixedly mounted at the other end of the bottom of the detection frame 1. The bottom of the piston cylinder 14 is connected to a connecting rod 17 via an air supply assembly. A piston plate 15 is slidably disposed inside the piston cylinder 14, and a connecting rod 17 is provided at the top of the piston plate 15. A movable frame 16 is provided at the outer end of the top of the connecting rod 17, and the movable frame 16 is disposed outside the piston cylinder 14. A one-way screw 18 is threadedly connected to the movable frame 16, and both ends of the one-way screw 18 are rotatably connected to the detection frame 1 via connecting bearings. A rotation drive assembly for driving the one-way screw 18 to rotate is installed on the detection frame 1.

[0022] This invention uses a clamping component to clamp the car tire. By sealing the tire sealing connector 9 to the tire's air inlet, the tire pressure detector 6 can perform tire pressure detection through the first connecting hose 8 and the first connecting pipe 7. After the tire pressure is detected, the one-way screw 18 is driven to rotate by the rotation drive component. The one-way screw 18 drives the threaded movable frame 16 to move, and the movable frame 16 drives the piston plate 15 to move. The piston plate 15 replenishes the tire pressure through the air supply component, thus facilitating the tire pressure detection process.

[0023] See Figure 1In one embodiment of this utility model, the rolling assembly includes a support leg 2 fixedly connected to the bottom of the detection frame 1. A roller 3 is provided at the bottom of the support leg 2, and a brake 4 is provided at the outer end of the roller 3. The roller 3 and the brake 4 can facilitate the control of the device to perform movement and position adjustment, thereby facilitating the use of the detection device.

[0024] See Figure 3 In one embodiment of this utility model, the tire clamping assembly includes a rotating rod 10 rotatably connected to the bottom of the detection frame 1. The top of the rotating rod 10 is provided with a mounting groove 11, and telescopic rods 12 are inlaid at the four corners of the mounting groove 11. An arc-shaped inner ring clamping plate 13 is provided at the telescopic end of the outer end of the telescopic rod 12. The arc-shaped inner ring clamping plate 13 is driven to move outward by the telescopic rod 12 to contact and clamp the inner side of the car tire, thus realizing the clamping treatment of the car tire.

[0025] See Figure 4 In one embodiment of this utility model, the rotation drive assembly includes a drive motor 19 fixedly connected to the inner wall of the detection frame 1. A drive gear 20 is mounted on the motor shaft of the drive motor 19, and a driven gear 21 is meshed on the drive gear 20. The driven gear 21 is connected to a one-way screw 18. When the drive motor 19 works, it drives the drive gear 20 to rotate the meshed driven gear 21. The driven gear 21 can drive the one-way screw 18 to rotate.

[0026] See Figure 3 In one embodiment of this utility model, the air supply assembly includes an air replenishment pipe 22 that is conductively connected to the bottom of the piston cylinder 14. The air replenishment pipe 22 is connected to a second connecting pipe 24 via a second connecting hose 23. The second connecting pipe 24 is conductively connected to a first connecting pipe 7. During the downward movement of the piston plate 15, the piston plate 15 pushes the gas inside the piston cylinder 14 to supply air to the first connecting pipe 7 through the air replenishment pipe 22, the second connecting hose 23, and the second connecting pipe 24. The first connecting pipe 7 supplies air to and vents the tire through the first connecting hose 8 and the tire sealing connector 9, thereby facilitating tire pressure adjustment.

[0027] Working Principle: This utility model installs the car tire on the outside of the mounting groove 11. The telescopic rod 12 drives the arc-shaped inner ring clamping plate 13 to move outward and contact the inner wall of the car tire, thereby clamping the car tire. After clamping, the car tire is sealed to the car tire's air inlet through the tire sealing connector 9. The tire pressure detector 6 detects the tire pressure through the first connecting pipe 7 and the first connecting hose 8. When the tire pressure is lower than the specified requirement, the drive motor 19 operates, driving the drive gear 20 to rotate the driven gear 21. The driven gear 21 rotates the one-way screw 18, which moves the threaded movable frame 16. The movable frame 16 moves the piston plate 15 through the connecting rod 17. The piston plate 15 supplies air to the first connecting pipe 7 through the air replenishment pipe 22, the second connecting hose 23, and the second connecting pipe 24. Together with the first connecting hose 8 and the tire sealing connector 9, the car tire is pressurized, thus facilitating the use of the car tire.
