Description

Programmable tire condition detector of flexible shell type, tire equipped with it and its mounting method {PROGRAMMABLE TIRE-CONDITION SENSOR HAVING A FLEXIBLE SHELL, ITS INSTALLATION METHOD AND A TIRE CARRYING SAME}

TECHNICAL FIELD The present invention relates to measurement of tire pressure, and more particularly, to a programmable tire condition detector of a flexible shell type, a tire equipped with the tire, and a mounting method thereof.

At present, in order to secure the safety of the vehicle by measuring values such as temperature and pressure in the tire, a detector for detecting a tire state is mounted on tires of many vehicles. For example, US Pat. No. 5218861 discloses a detector installed in a tire structure. This patent is not only difficult to maintain because the detector is embedded in the rubber of the tire, but also the position where the detector is embedded is farthest from the central axis of the tire and has the greatest centrifugal force. However, the buried position is the position where the deformation amount is the largest and the most unstable in the process of driving the tire, and the position is most easily drilled by foreign matter. Therefore, when the detector is installed in this position, it is most likely to be damaged. In addition, when the tire is disposed of and recovered, the electronic parts embedded in the rubber become a problem in the recovery process.

On the other hand, US patent 5573611, for example, discloses a tire condition detector. This patent has the disadvantage of not being able to maintain or replace the battery since the detector is mounted on the tire after being packaged by the packaging material. In addition, since the tire is deformed according to the state of the road during the driving process, the detector mounted in the tire preferably forms the largest deformable area or is deformable according to the deformation of the tire. However, the method used by the patent is, on the contrary, a method of packaging the detector through packaging, thereby increasing an area that is not deformed. This can increase the probability that the detector will be damaged when the tire is deformed.

In addition, Taiwan Patent No. 1252817 discloses an attached tire condition detection device. This patent has the disadvantage that the detection device is installed on the wheel of the tire. Wheels are typically made of metal such as iron or aluminum alloys, which can interfere with or block the transmission of LF or RF signals. In addition, it is difficult to attach and fix the detector to the metal surface, and it is difficult to attach the detector to the metal surface, thereby easily dropping off.

It is an object of the present invention to provide a flexible shell type programmable tire condition detector having a simple structure, easy to operate and maintain, and not easily damaged, a tire equipped with the same, and a mounting method thereof.

In order to achieve the above object, the flexible shell type programmable tire condition detector of the present invention includes a control module and a flexible housing.

The control module includes a circuit board on which a battery pack for supplying power is installed; A power switch controlling on / off of battery pack power; A memory capable of reading and writing redundancy and a processor electrically conductive to the memory; A pressure detector mounted to the circuit board and electrically connected to the processor to detect a pressure value in the tire; A temperature detector electrically connected to the processor to detect a temperature in the tire; An acceleration detector electrically connected to the processor to detect an acceleration value in the tire; A voltage detector for detecting a voltage of the battery; A transmission interface electrically connected with the processor to transmit a value detected from a pressure detector, a temperature detector and an acceleration detector to a receiving body of the vehicle; And a connection port connecting the circuit board and the connection head of the external transmission line.

The area of the flexible housing is larger than the area of the circuit board, and a swelling area is formed in the middle portion thereof, and the opening may be engaged with the power switch so that the opening and the power switch are exposed to the switch hole in the flexible housing. The switch hole and the connection hole which can be engaged with the corresponding connection port is provided.

The present invention can also provide a tire equipped with the flexible shell type programmable tire condition detector.

The present invention can also provide a method of mounting a flexible tire type programmable tire condition detector.

According to the present invention, the flexible shell-type programmable tire condition detector can be located close to the vehicle body to ensure stable and stable signal transmission quality.

Taking the following two examples as examples, the features and effects of the present invention will be described in detail.

[First Embodiment]

1 to 5 show a first embodiment of the present invention. A flexible shell type programmable tire condition detector according to the invention is mounted on a tire of a vehicle. The flexible shell type programmable tire condition detector includes a control module 10 and a flexible housing 20.

The control module 10 includes a circuit board 11 provided with a battery pack 12 for supplying power; A power switch 13 for controlling on / off of the battery pack 12 power; A memory (not shown) capable of reading and writing redundantly and a processor (not shown) in electrical communication with the memory; A pressure detector (14) mounted on the circuit board (11) and electrically connected to the processor to detect a pressure value in the tire; A temperature detector 15 electrically connected with the processor to detect a temperature in the tire; An acceleration detector 16 electrically connected with the processor to detect an acceleration value in the tire; A voltage detector (not shown) for detecting a voltage of the battery; A low frequency (LF) transmission interface and a radio frequency (RF) transmission interface (not shown), which are electrically connected to the processor to detect from the pressure detector 14, the temperature detector 15, and the acceleration detector 16. A transmission interface for transmitting the received value to a receiving body in a vehicle by LF or RF method; And a connection port 17 for connecting the circuit board 11 to a connection head of an external transmission line.

The flexible housing 20 is made of natural rubber or synthetic rubber and can be easily and firmly attached to the inner wall of the tire because the material for manufacturing is similar to a tire. An area of the flexible housing 20 is larger than an area of the circuit board 11, and a swelling area 21 is formed in an intermediate portion, and a bottom of the swelling area 21 and a bottom of the flexible housing 20 are formed. The height difference between the outer edge bottoms is smaller than the height of the control module 10. An opening 22 in the flexible housing 20; A switch hole 23 that can be engaged with the power switch 13 so that the power switch 13 is exposed to the switch hole 23; And a connection hole 24 that can engage with the connection port 17. The flexible housing 20 protrudes walls 231 and 241 surrounded by the switch hole 23 and the connection hole 24 so as to be engaged with the power switch 13 and the connection port 17. It is installed.

According to the structure, when using the flexible shell type programmable tire condition detector according to the present invention, the mounting method first covers the control module 10 with the flexible housing 20, but the switch hole 23. ) Corresponds to the power switch 13 and the connection hole 24 corresponds to the connection port 17. The outer peripheral edge of the assembled flexible housing 20 is then sized and attached to the inside of the bead filler of the tire 1 in a thermocompression manner. This is because the position is the position where the tire deformation is the smallest. Most preferably, the position is opposite the tire air inlet. This arrangement allows the flexible shell-type programmable tire condition detector to be located close to the vehicle's bodywork, ensuring stable and stable signal transmission quality. In addition, since the height of the swelling area 21 is smaller than the height of the control module 10, after attaching the flexible housing 20, the control module 10 is connected to the flexible housing 20 and the tire. (1) It is fixed between the inner tire walls and there is no remaining space. Therefore, a situation in which the control module is shaken or loosened does not occur.

After fixing the flexible housing 20, the control module 10 and the external operation body are connected through a transmission line to load a transmission, an encoding program, and related settings, which are already selected, into the memory of the control module 10. do. After the operation of the loading program is completed, the transmission line is removed and the power switch is turned on. The flexible shell type programmable tire condition detector is then ready for use.

The advantage of the present invention is to lower the probability of damaging the detector by maximally increasing the deformable area of the tire condition detector using a flexible housing. In addition, since the memory of the control module 10 can read and write redundantly, when the tire position changes, for example, when the front wheel and the rear wheel are exchanged, the user adjusts the related setting after connecting the transmission line to the connection port. Just do it. When the tire is disposed of and recovered, the flexible housing 20 can be removed and the control module 10 can be directly removed, so that the flexible housing 20 can be recovered together with the tire. Does not cause either.
