DETAILED DESCRIPTION

[0027] The specific embodiment is a tire pressure sensor structure with air supplementing and pressure relief functions, and a structure schematic diagram thereof is shown in the figure. Figures 1-6 The structure includes a shell 1, which can be made of aluminum or high-strength plastic, and an accommodating cavity 2 is formed in the inside of the shell 1. An automatic pressure relief assembly 3 and an air nozzle connecting hole 4 that communicate with the accommodating cavity 2 are arranged on the left side of the shell 1. The automatic pressure relief assembly 3 is used for tire pressure relief, and the air nozzle connecting hole 4 is stepped, internally installs a sealing gasket 6 and is used for detachable connection with a tire air nozzle. When installing, the cap of the tire air nozzle is unscrewed, and the air nozzle connecting hole 4 on the shell 1 is threadedly connected with the air nozzle of the vehicle tire. At this time, the tire pressure sensor can be installed at the tire air nozzle, and the sealing gasket 6 prevents air leakage.

[0028] The inside of the accommodating cavity 2 internally installs an air pressure sensing assembly 5, which is used for real-time acquisition of tire pressure and wireless radio frequency connection with the central control of the vehicle.

[0029] As shown in the figures, Figure 1 And Figure 2 In the embodiment, the shell 1 includes a base 101 and a lid 102. The right side edge of the base 101 is fixedly connected with a threaded column 103, the threaded column 103 is threadedly connected with the lid 102, and a sealing ring 104 is arranged between the base 101 and the lid 102.

[0030] In this way, the base 101 and the lid 102 can be disassembled to expose the internal accommodating cavity 2, and the air pressure sensing assembly 5 is more convenient to install and disassemble.

[0031] AsFigure 2 and Figure 3 As shown in the figure: in this embodiment, the left side of the base 101 is fixedly connected with a hexagonal column 105, and the air nozzle connecting hole 4 penetrates through the hexagonal column 105.

[0032] In this way, the tire pressure sensor can be rotated by using a tool through the hexagonal column 105, so that it is more closely connected with the tire air nozzle.

[0033] As shown in the figure Figure 1 and Figure 3 As shown in the figure: in this embodiment, the left side of the shell 1 is provided with a pressure relief hole 106 which is in communication with the accommodating cavity 2, and the automatic pressure relief assembly 3 is installed at the pressure relief hole 106. The inside of the pressure relief hole 106 also has a rubber ring for sealing. When the internal pressure is too large, in order to prevent explosion or explosion of the cover 102 to hurt people, the excess gas inside can be discharged through the pressure relief hole 106, that is, when the air pressure is greater than the preset air pressure value, the air pressure valve inside the pressure relief hole 106 will be opened to discharge gas.

[0034] In this way, without disassembling the tire pressure sensor, the automatic pressure relief assembly 3 can be used to discharge and inflate. The automatic pressure relief assembly 3 and the pressure relief hole 106 can be threadedly connected, and a sealing structure is arranged inside. It is not only convenient to install, but also will not leak.

[0035] As shown in the figure Figure 2 and Figure 3 As shown in the figure: in this embodiment, the air pressure sensing assembly 5 includes a control panel 501, a pressure sensor 502, a wireless transmission module 503 and a battery 504. The control panel 501, the pressure sensor 502, the wireless transmission module 503 and the battery 504 are electrically connected. The pressure sensor 502 is used to obtain the tire pressure in real time. The wireless transmission module 503 is used to be connected with the central control wireless radio frequency of the vehicle. The automatic pressure relief assembly 3 can be electrically connected with the control panel 501 to realize automatic pressure relief.

[0036] In this way, the battery 504 provides power for the control panel 501, the pressure sensor 502 and the wireless transmission module 503. The central control of the vehicle can also be connected with the mobile phone, and the air pressure value can also be seen on the mobile phone.

[0037] As shown in the figure Figure 2 and Figure 4 As shown in the figure: in this embodiment, a plurality of through holes 505 are formed on the control panel 501, a plurality of threaded holes 107 are formed on the right side of the threaded column 103, a countersunk screw 506 is arranged in the through hole 505, the countersunk screw 506 penetrates through the through hole 505 and is threadedly connected with the threaded hole 107, an installation groove 108 is formed on the right side of the threaded column 103, and the pressure sensor 502 is installed in the installation groove 108.

[0038] In this way, the control panel 501 can be fixed with the base 101, preventing the control panel 501 from shaking in the accommodating cavity 2.

[0039] As shown in Figure 2 and Figure 5 In this embodiment, the right side of the control panel 501 is provided with a U-shaped bracket 507, and the right side of the U-shaped bracket 507 is integrally formed with an elastic sheet 508. The battery 504 is fixed to the right side of the control panel 501 through the U-shaped bracket 507 and the elastic sheet 508.

[0040] In this way, the battery 504 is more convenient to install. When the battery 504 is a button battery, the elastic sheet 508 on the U-shaped bracket 507 can be electrically connected to one end of the button battery, simplifying the connection circuit of the battery 504.

[0041] In this embodiment, when the air pressure sensing assembly 5 detects that the air pressure seal leaks and exceeds the pressure value of the accommodating cavity 2, the automatic pressure relief assembly causes the pressure relief hole 106 to be opened, and the tire will be relieved of pressure, avoiding the expansion of the injection shell 1 under pressure to injure people.

[0042] Working principle: when installing, unscrew the cap of the tire air nozzle, and threadedly connect the air nozzle connecting hole 4 on the shell 1 with the air nozzle of the tire. At this time, the tire pressure sensor can be installed at the tire air nozzle. When using, the pressure of the tire is obtained in real time through the pressure sensor 502 and the signal is transmitted to the control panel 501. When the control chip CPU on the control panel 501 detects that the tire air pressure is too low, the signal is transmitted to the wireless transmission module 503. The wireless transmission module 503 is connected to the central control of the vehicle through wireless radio frequency, and the user can be reminded to supplement air. When the control chip CPU on the control panel 501 detects that the tire air pressure is too high, the signal is transmitted to the wireless transmission module 503. The wireless transmission module 503 is connected to the central control of the vehicle through wireless radio frequency, reminding the user to release air. At this time, the automatic pressure relief assembly 3 can cause the pressure relief hole 106 to be opened, and the tire will be relieved of pressure. Since the tire pressure sensor structure belongs to an external product, when one of the tire pressure sensors is damaged, it can be replaced and disassembled at any time without the need to disassemble the whole tire. Not only is the operation simple, but also the maintenance cost is reduced.

[0043] All the technical features in the embodiment can be freely combined according to actual needs.

[0044] The above embodiment is a preferred implementation scheme of the present application. In addition to this, the present application can also be implemented in other ways. Any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
