Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a TPMS tire pressure monitoring structure with a straight air outlet nozzle fixed thereon. Background Art

[0002] TPMS is a device that can monitor tire pressure and temperature in real time. It monitors the internal pressure and temperature of the tire through sensors installed in the tire, and uses wireless radio frequency to send the pressure and temperature data information collected by the sensor to the TPMS signal receiver. After processing, the data is compared with the preset threshold. When the tire pressure is abnormal, the alarm light is turned on, the alarm tire pressure is displayed, and text prompts and sound prompts are issued to remind the owner of the current abnormal status of the tire.

[0003] Existing built-in tire pressure sensors are generally fixed on the side air valve of TPMS. This air valve fixing structure is suitable for wheels with larger space. However, this fixing structure is less adaptable to small wheels. TPMS usually requires an intermediate locking screw for fixing, which is beneficial for the use of wheel specifications with small space and can save space inside the tire. Utility Model Content

[0004] The purpose of the utility model is to provide a TPMS tire pressure monitoring structure with a straight air nozzle, which can solve the problem that the existing built-in tire pressure sensor is generally fixed on the TPMS side air nozzle, avoid the situation that the air nozzle fixing structure is only suitable for wheels with larger dimensions and space, and avoid the problem that the tire cannot be used due to insufficient space inside the tire due to the large fixing structure. It can solve the problem that when some fixing mechanisms encounter tire repair, the air nozzle hole may be blocked by tire repair fluid, and avoid the problem that the tire pressure monitoring device may lose its function due to tire repair fluid.

[0005] To achieve the above object, a TPMS tire pressure monitoring structure with a straight air outlet nozzle is provided, comprising a wheel hub, a tire pressure monitoring device is provided above the wheel hub, and a locking screw is provided above the tire pressure monitoring device;

[0006] An air valve body is provided below the tire pressure monitoring device, a protruding block is fixedly connected to the inner ring of the wheel hub, and a rim is fixedly connected to the side surface of the wheel hub.

[0007] According to the straight air outlet nozzle fixed TPMS tire pressure monitoring structure, a groove is provided on the lower surface of the tire pressure monitoring device, and a tire pressure monitoring air hole is provided on the surface of the groove.

[0008] According to the straight-outlet air nozzle fixed TPMS tire pressure monitoring structure, a first locking screw hole is opened at the center position of the tire pressure monitoring device, and an air nozzle matching limiting groove is provided below the first locking screw hole.

[0009] According to the straight-outlet air nozzle fixed TPMS tire pressure monitoring structure, a clearance groove is provided above the air nozzle body, and a second locking screw hole is provided above the clearance groove.

[0010] According to the straight-outlet air nozzle fixed TPMS tire pressure monitoring structure, the left side of the air nozzle body is engaged with the air nozzle cap.

[0011] According to the straight air outlet nozzle fixed TPMS tire pressure monitoring structure, the upper and lower surfaces of the tire pressure monitoring device are both arc-shaped.

[0012] According to the straight air outlet nozzle fixed TPMS tire pressure monitoring structure, the tire pressure monitoring air hole is located on the lower surface of the tire pressure monitoring device.

[0013] The utility model has the following beneficial effects:

[0014] 1. Compared with the prior art, this structure, which utilizes a tire pressure monitoring device (TPMS) fixed with a straight-outlet valve, facilitates installation of the TPMS in smaller wheel hub spaces by arranging the TPMS, a locking screw, a valve body, and a wheel hub. The locking screw facilitates securement of the TPMS and evenly distributes force, minimizing wobble at both ends once the TPMS is secured. Furthermore, the TPMS air hole is located on the lower surface of the TPMS, effectively preventing sealant fluid from clogging the valve hole and potentially causing the TPMS to lose functionality. Furthermore, the curved surface of the TPMS effectively reduces the height of the TPMS installed within the wheel hub, preventing damage to the TPMS by scratches during tire installation and removal. This solves the problem of existing built-in tire pressure sensors typically being fixed to the TPMS side valve, avoids the situation where this valve fixing structure is only suitable for larger wheels, and avoids the problem of the mounting structure being too large to allow for sufficient space inside the tire, rendering the tire unusable.
