Example Embodiment

[0039] The present invention will be further described below in conjunction with the drawings and embodiments:

[0040] figure 1 with figure 2 The assembly relationship between the tire pressure gauge and the air nozzle connection structure of the present invention is shown together. The tire pressure gauge 1 is mainly composed of a housing 11 and a circuit board 12. The circuit board 12 integrates parameters such as tire pressure, temperature and / or humidity. The circuit 123 of the detection means is also integrated with the transmission circuit 121 that sends the detection result in the form of a signal (see Figure 5 with Image 6 ), and the integrated battery 122 as a power source. The circuits used by the tire pressure gauge 1 can be integrated on the same circuit board 12, figure 1 On the circuit board 12 shown, the integrated circuits on it have been omitted, but the Figure 5 The circuit board 12 shown shows a typical specific circuit integration component on the tire p...

Abstract

The invention discloses a tire pressure gauge and air faucet connecting structure which comprises a universal head, a conductive coating film, a first mating piece and an insulating fixing piece; the universal head is arranged on the tail end of the axial direction of the air faucet, and is provided with a second mating piece; the conductive coating film is fixed on an outer shell, and comprises a film body, a tongue piece which extends into the outer shell form the film body and is electrically connected with a transmission circuit in a circuit board, and a guide groove penetrated to the film body; the film body is provided with an inner concave spherical surface and an outer convex spherical surface; the universal head is universally connected with the inner concave spherical surface, and is concentric with the outer convex spherical surface; the first mating piece comprises a limiting piece; the insulating fixing piece is sleeved on the periphery of the air faucet so that the air faucet is fixed with a hub in an insulating way; the two mating pieces are mutually fixed in a matched way through the guide groove; and the signals of the transmission circuit of the tire pressure gauge are transmitted to the space sequentially through the conductive coating film, the first mating piece, the second mating piece, the universal head and the air faucet. The tire pressure gauge and air faucet connecting structure can ensure the high-efficiency and reliable transmission of the signals while ensuring the tire pressure gauge and the air faucet are stably connected and rotate flexibly, and can minimize the economic losses caused by the hitting to the tire pressure gauge.

Description

【Technical field】 [0001] The invention relates to automobile security auxiliary equipment, in particular to a connection structure between a tire pressure gauge and an air nozzle. 【technical background】 [0002] It is common knowledge in the art that the tire pressure gauge of the automobile tire is connected with the air nozzle to form an independent product for sale. See the patent documents of various countries in the world including the applicant's patent (application) for the relevant technological evolution. [0003] The connection structure between the tire pressure gauge and the air nozzle disclosed in the known patent documents not only considers the structure of transmitting the internal signal of the tire pressure gauge through the air nozzle and realizes the physical connection between the tire pressure gauge and the air nozzle, but also maintains the tire pressure. A structure in which the meter and the gas nozzle are not electrically connected but physically c...
