The specific embodiment
Below in conjunction with Figure of description a kind of tire pressure test warning of the present invention is further described in detail.
Just be based on direct-type tire pressure monitoring system of the prior art, and proposing various embodiment of the present invention.
Such as Fig. 1, in a kind of preferred forms of the present invention, this tire pressure test warning comprises tyre pressure sensor 1, receptor 2, telltale 3 and annunciator 4.Wherein, tyre pressure sensor 1 and receptor 2 wireless connections, receptor 2 and telltale 3 wired connections, telltale 3 also with annunciator 4 wired connections.Wherein, tyre pressure sensor 1 is installed on the tire of vehicle, and receptor 2, telltale 3 and warning device 4 are installed in the operator's compartment of vehicle.
Such as Fig. 2, shown in Figure 3, the tyre pressure sensor 1 in the present embodiment comprises shell 11, monitoring pcb board 12 and tire valve 13.Wherein, shell 11 comprises upper shell 11a, lower house 11b, and upper shell 11a and lower house 11b are glued together, and monitoring pcb board 12 is fixedly installed in the shell 11.Bottom at the outer wall of lower house 11b is provided with the 11b ' of department of assembly, is used for tire valve 13 is fixedly mounted on shell 11.The 11b ' of department of assembly is provided with a cell body 11b ", and cell body 11b " with the internal communication of shell 11.One sheetmetal 14 and cell body 11b " shape insert cell body 11b suitablely " in, and be connected with 12 contacts of monitoring pcb board.The corresponding position is respectively equipped with assembly opening 111b ', perforation (not shown) on the 11b ' of department of assembly, the sheetmetal 14, and a screw 15 passes assembly opening 111b ' successively, the perforation (not shown) is connected with the rear portion of tire valve 13.In the present embodiment, tire valve 13 comprises valve inside 131, rubber coating 132, wherein, rubber coating 132 is enclosed within the outside of valve inside 131, and the front portion of valve inside 131 is threaded with a valve cap 133, and the rear portion of valve inside 131 has a screw mounting hole (not shown), screw 15 passes assembly opening 111b ' successively, perforation (not shown) rear thread is connected in the screw mounting hole, thereby tire valve 13 is fixedly mounted on the shell 11.Simultaneously, because sheetmetal 14 is connected with the contact of monitoring pcb board 12, sheetmetal 14 contacts with the rear portion of valve inside 131 by screw 15 and is connected, and links together by indirect contact thereby will monitor pcb board 12 and valve inside 131.In addition, sheetmetal 14, screw 15 in the present embodiment are made by stainless steel material respectively, and valve inside 131 is made of copper.
