[Embodiment] The present invention will be described in detail below with reference to the drawings. Among them, FIG. 1 is an external perspective view of the tire pressure warning device according to the present invention, FIG. 2 is an exploded view of the tire pressure warning device according to the present invention, and FIG. Figure 4 is a cross-sectional view of the tire pressure warning device of the present invention when the tire pressure is insufficient. As shown in these figures, the tire pressure warning device of the present invention includes a metal casing, a valve nozzle device 2, and a membrane. The sheet 3, a sleeve 4, a push rod 5 ', an elastic element 6, a battery device 7, a launch device 8, and a cover body 9. The metal case 1 is formed with a horizontal partition ^ inside the metal case 1, and the horizontal case 11 partitions the metal case into an upper container 12 and a lower container 13. The transverse partition Η is provided with a central hole 14, and the metal shell is provided with an inner shoulder 15 at a position near the top of the upper valley to 12. The valve nozzle device 2 is installed in the lower chamber 13 of the metal casing 1. The reading mouth dress 2 includes a question mouth 21 and a set of rings 22, which are passed around the outer mouth 21 ', and the top of the wide mouth 21 is protruded in metal 200539065. The body 1 is a horizontal partition. 1 1 的 中心 不 丨】 n i4. The metal casing 1 has internal threads 16 'inside the lower rim 3 and 3, which can be screwed to the valve of the tire (not shown), and the valve device 2 can lift the valve to make the tire The inside is introduced into the metal case via the wide mouth device 2!上部 容 室 12. ㈣The above-mentioned cymbal plate 3 is installed on the top surface of the horizontal partition U of the metal casing i. The outer ring portion 31 and the inner ring deformation portion 32 of the two-body molding are in the form of: == inner & domain. The cross-sectional shape of the inner ring deformed portion 32 of the cymbal is greatly deformed, and the bent skin π-shaped portion has a large deformation space. If the deformation part is also provided, the deformation can be provided with a concave ring groove 33, which can be used to support the central portion of the lower shape 胄 32 to 仏 bear the bottom of the pusher 5 described below. The upper chamber of the metal casing 1 is installed on the film ... and the tube portion is: :::::: 广 ^ 展 Further opening P is fixed against the outside of the diaphragm 3, and only 1 ^ 衣 〇p 31, so that The outer ring portion 31 is deformed and moved. ≪ Inner% deformation section 32 can come into contact with the inside of the sleeve 4 in accordance with the tire pressure. The bottom of the pusher 5 touches the second diaphragm. For example, the pusher 5 is a tubular pusher 'inner ring deformed part 32 and the concave ring groove 33 of the y ° P 32 can be moved up with the heart. i Shen and ~ 7 / Λ. The top of the push rod passes through the through hole of the sleeve 4 and the top of the push rod 5 is provided with a metal contact plate 51 and 200539065. An example of an assembly shoulder σP 1 5 is straddled between the vertical rods of the metal casing 1. The installation method of the metal contact plate 51 and the push-fitting adopts a screw IS: fixed type installation or adopts, for example, the screw 51 and the pusher 5 body door-type τ, which can adjust the metal contact plate to resist elastic force, and The relative distance 'further adjusts the near bottom 12 of the push rod 5 of the following elastic element 6: the warning indicates the set value when the tire pressure is insufficient. Again, piece 6. It is formed with a transverse convex ring 52 for carrying the elastic element between the top plate 42 of the above-mentioned remote elastic element 6 and the cylinder 4. The convexity 52 and the sleeve 6 are provided with a returning elastic force: t . The elastic element is larger than the elastic element ΓΛ elastic; Wheel force. #Tire pressure is normal and ^ elastic force 4, the tire pressure system will cause the internal deformation deformation portion 32 of the diaphragm 3 to protrude upward by ψ material f ^ and deform the push rod 5 and the metal contact plate 51 ' The metal contact plate 5 i comes out of contact with the shoulder portion ^ of the metal case 1; on the contrary, when the tire pressure is insufficient and less than the elastic force of the elastic member 6, its metal contact plate 51 remains in contact with the inner shoulder portion. The contact relationship. The battery device 7 is installed on the top surface of the metal contact plate 51, and the battery device 7 is in contact with the metal contact plate 51 by its negative electrode, and then is conducted to the emitting device 8 through the metal case 1. The positive electrode of the battery device is connected to the transmitting device 8 through a conductive element 71. The transmitting device 8 is installed on the top of the conductive element 71 and the metal casing j. When the power is turned on, a signal can be transmitted to the outside, and a receiver (usually installed in the car is easily visible to the driver). Position, not shown) to alert the tire pressure. The transmitting device includes a circuit board 200539065 81, which is in contact with the conductive element 7 丨 and the metal case respectively, and is connected to the positive and negative power sources of the battery device. The cover 9 is installed on the outer periphery of the top portion of the metal casing 丨 by means of screwing, for example, to cover and fix the above-mentioned members. In addition, an insulating sleeve 53 is sleeved between the outer periphery of the metal contact plate 51 and the inner wall of the metal casing 丨 to isolate the metal contact plates Η and the metal casing 1 from improper lateral contact. When the tire pressure warning device of the present invention is used, the internal thread 16 of the metal casing is screwed to the tire nozzle, and the valve nozzle device 2 opens the nozzle, so that the air inside the tire passes through the valve nozzle device 2 It is introduced into the upper chamber 12 of the metal case 1. As shown in Figure 3, when the internal air pressure of the tire is sufficient and normal, the tire pressure system will cause the inner ring deformation portion 32 of the diaphragm 3 to protrude upward and open j, and push the push rod 5 and the metal contact plate 51 upward. As a result, the metal contact plate 51 comes out of contact with the inner shoulder portion 15 of the metal case 丨, at this time, the difference comes from the metal contact plate 51-the negative electrode of the battery device 7 is not connected to the emission position 8, That is, the power supply line of the transmitting device 8 is in an open circuit, and it is unable to transmit a signal 'that is, the receiver has not received a signal', indicating that the tire pressure 0 at this time is normal. As shown in FIG. 4 'When the air dust inside the tire is insufficient, the wheel and pressure cannot oppose the elastic force of the elastic element 6 to push the push rod 5 and the metal contact plate W 5 upwards. Because Λ, the metal contact plate 51 depends on The elastic city of the elastic element 6 maintains the contact relationship with the inner shoulder portion 15. At this time, the negative electrode of the battery pack 7 which comes from the metal contact phase 5! Is connected to the launching device 8, so that the 200539065 launching device 8 The Lei Lu pole ^ /, pen ,, and Yuan road form a pathway, and a signal can be transmitted outward, and the receiving receiver receives the signal and uses, for example, a light warning to indicate whether the tire at this time is insufficient and must be Check the tires or inflate. When the circuit is switched on, the base-+ t has a negative charge, and the same polarity as the tire, so there is no risk of short circuit or malfunction. According to the structure of the present invention, its assembly is extremely simple, and the outer metal shell can be used for a variety of applications within the scope of the technical idea of the present invention. 'As long as the effects of the present invention can be exerted, such application implementation should also be It is understood to be included in the patent application scope of the present invention. To sum up, the present invention provides a structure of a tire pressure warning device, which is "a highly innovative method that utilizes the laws of nature. Its structure has novel creativity and improved practicality." Please grant protection for invention patents.
