Description

Tire detecting device

The present invention relates to the technical field of sensing, and in particular to a tire detecting device.

The tire is mounted on a vehicle to help the vehicle travel on the road surface. The tire is a rubber ring that can be embedded in the outer periphery of a rim. The two together form a space filled with gas to support the tire to maintain a full use state, and to provide a cushioning effect on the vehicle traveling on the road.

However, if the tire pressure is too large, the tire may be deformed. If the tire pressure is low, the tire will be crushed by the weight of the vehicle, which not only hinders the vehicle from running, but also reduces the speed of driving, which has a serious impact on traffic safety.

Amateur maintenance personnel, due to lack of experience, only use air compressors to fill the tires. After a period of time, the tire is pressed by hand to determine whether the gas is sufficient, and the drawback of misjudgment is easy to occur.

Professional maintenance personnel will use a tire pressure gauge to detect the tire pressure, and determine whether the tire pressure is in the normal range according to the pointer of the tire pressure gauge. However, during the visual inspection, because of the deviation of the visual angle, the pointer and the scale cause an error between each other, and the judgment of the influence value is very large.

Therefore, how to improve the tire detecting device has become an urgent problem to be solved in this creation.

In view of this, this creation provides a new tire detection device, the main purpose is to use an electronic detection structure, with a trigger-type inflatable structure, ready to inflate according to tire pressure data operation.

Due to the above object, the tire detecting device of the present invention comprises: a casing having a front flow passage and a rear flow passage, and a valve body is installed at the front and rear flow passages, the valve body is determined before and after. Whether the flow path is connected; a first pipe body having one end connected to the front flow passage of the outer casing and the other end being detachable by combining the nozzle of a tire; and a second pipe body having one of the two ends connected to the rear flow path of the outer casing The other end directs the flow of the high pressure gas to the outer casing; and a control system is disposed in the outer casing, and the internal pressure of the tire is measured by the control system and the value is recorded.

Specifically, a trigger is externally connected to the outer casing to trigger the valve body to connect the front and rear flow passages. Wherein, the outer casing has a grip portion, and the grip portion is connected to a main body. The trigger is disposed at a junction of the grip portion and the body, which is swingable relative to the grip portion.

In addition, the control system is disposed in the main body and has a microprocessor electrically connected to a power module, a display module, a communication module, a detection module, a memory module, and a Input/output module. When the detection module senses the gas pressure of the front flow channel, the detection module outputs a message, and the microprocessor receives the message and converts it into a value appearing in the display module.

The display module includes a main screen and a portable communication device screen, so that one user can selectively view one of the two screens. Wherein, the main screen refers to the screen being embedded on the main body. The portable communication device screen means that the screen is arranged on a portable communication device such as a smart phone or an iPad.

Figure 3 is a configuration diagram of the control system.

Figure 4 is a flow chart of use.

Referring to FIGS. 1 and 2, a specific structure of a preferred embodiment of the tire detecting device 10 is illustrated. A housing 12 is connected to a first tube 20 and a second tube 22, and a control is disposed on the housing 12. The system is used for the measurement of the internal pressure of the two tires (not shown) and the value of the record.

The outer casing 12 has a grip portion 14 that is designed to be integral with a main body 16 in terms of appearance. A trigger 18 is disposed at the junction of the grip portion 14 and the body 16, which is swingable relative to the grip portion 14. The outer casing 12 is hollow inside and has a front flow passage 11, a rear flow passage 13 and a valve chamber 17 connecting the front and rear flow passages 11, 13. The front flow passage 11 communicates with the inside of the main body 16, and the rear flow passage 13 is formed inside the grip portion 14, and the valve chamber 17 is mounted with a valve body 15. Normally, the valve body 15 contacts the trigger 18 to remain closed, so that the front and rear flow passages 11, 13 are blocked. When the trigger 18 approaches the grip portion 14, the valve body 15 is pressed by the trigger 18 to communicate the front and rear flow passages 11, 13.

One of the two ends of the first pipe body 20 is connected to the front flow passage 11 of the outer casing 12, and the other end is detachably coupled to a gas nozzle (not shown) provided on the tire. The second pipe body 22 is connected at one end to the rear flow passage 13 of the outer casing 12, and the other end is connected to an air compressor (not shown).

It is not difficult to understand from Figures 3 and 4 that the control system 30 is disposed in the main body 16 (e.g., the second In the figure, there is a microprocessor 32. The microprocessor 32 is electrically connected to a power module 34, a display module 36, a communication module 38, a detection module 31, a memory module 33, and An input/output module 35.

The first is the "Start 40" step: after the power module 34 is turned on, the power required by the control system 30 is supplied.

This is followed by a "read preset 41" step: the microprocessor 32 reads the initial value of the memory module 33 with respect to the tire pressure. In this embodiment, the memory module 33 is an electronic erasable read-only memory (EEPROM). Not only the preset value but also the measured tire pressure value can be recorded, which is convenient for the user to read at any time. The initial value of the tire pressure is "0" and is usually immutable. However, in some special (such as air-thin hills) environments, the user can adjust the initial value of the tire pressure through the input/output module 35 (such as a touch button).

In the step of "whether to correct the tire pressure value 42": because the detection module 31 does not have any feedback of the message, the target of the comparison is lacking. At this point, the microprocessor 32 logically determines that the tire detecting device 10 (see FIG. 2 for details) is in an idle state and displays a data equal to the initial value of the tire pressure on the display module 36.

The detection module 31 includes a pressure sensor (Pressure Sensor). The pressure sensor can sense or detect the change in air pressure of the front runner 11 (see Figure 2 for details). If the air pressure of the front runner 11 is normal, the pressure sensor will not deliver any message. Once any change in the air pressure of the front runner 11 occurs, the pressure sensor outputs an associated message to the microprocessor 32.

Thus, the "tire pressure value return to zero 43" step will typically be a program that is forced by microprocessor 32 in an attempt to display a "0" number on display module 36. The display module 36 displays a "0" number, which allows a user to determine that the tire detecting device 10 (see Figure 2 for details) is normal.

In the "Volume 44" step: the first pipe body 20 (see Fig. 2 for details) communicates with the inside of the tire, and relatively increases the air pressure of the front flow passage 11 (see Fig. 2 for details). At the moment, the pressure sensor detects When the change in the air pressure of the front flow path 11 is detected, a related message is output.

Finally, the step of "displaying the tire pressure value 45" is performed: the microprocessor 32 receives the message of the detecting module 31, and converts the corresponding value into the display module 36.

The display module 36 includes a main body screen 37 and a portable communication device screen 39 for facilitating a user to selectively view one of the two screens 37, 39. The main body screen 37 is a screen mounted on the surface of the main body 16 (see FIG. 2 for details), and is electrically connected to the microprocessor 32 in a wired mode. The portable communication device screen 39 is a screen of a portable communication device such as a smart phone or an iPad, and is electrically connected to the microprocessor 32 in a wireless mode through the communication module 38.

In the present embodiment, the display module 36 clearly informs the user that the current tire pressure is too high, normal or low in Arabic numerals. In some embodiments, the display module 36 exhibits a change in tire pressure by a color block, circle, or strip chart pattern.

When the tire pressure is too high, the pressure inside the tire is reduced by deflation. When the tire pressure is low, the trigger 18 activates the valve body 15 (see Fig. 2 for details) to keep the front and rear flow passages 11, 13 unblocked, and the second tubular body 22 guides the high pressure gas to be replenished inside the tire until the tire pressure Approaching the appropriate range set by domestic regulations or international regulations.
