Plug-in display instrument provided with standby interface and tire pressure status instrument

Abstract

The invention relates to a plug-in display instrument provided with a standby interface, which comprises a display component and an electrical plug, wherein the display component comprises a housing and a display screen that is mounted in the housing and used for achieving a display function; the electrical plug is plugged with an electrical interface of an automobile to take electricity and supply the electricity for the display screen; the housing of the display component is pivoted with the side of an exposure end of the electrical plug; and the standby interface electrically connected with the electrical interface of the automobile is arranged on the end face of the exposure end of the electrical plug. A tire pressure status instrument comprises a tire pressure monitoring circuit and a tire pressure signal receiving antenna, and adopts the plug-in display instrument with the standby interface, and the tire pressure monitoring circuit and the tire pressure signal receiving antenna are arranged in the display component. The plug-in display instrument provided with the standby interface and the tire pressure status instrument are small in size, optimal in design, convenient to use, wide in application, and multifunctional.

Description

technical field [0001] The invention relates to an auto accessory, in particular to a plug-in display instrument with a spare interface installed on a conventional cigarette light interface of an automobile, and also relates to a tire pressure state instrument using the display instrument. Background technique [0002] The application of external tire pressure gauges is becoming more and more widespread. Its basic principle is the built-in sensor installed on the tire hub, including a bridge-type electronic air pressure sensing device that senses air pressure. Send the signal to the receiver, display various data changes on the receiver's display or in the form of buzzer to remind the driver, and give an alarm when the tire leaks and the pressure change exceeds the safety threshold to ensure driving safety. [0003] The tire status display and alarm device is usually installed at the front of the cab, and the vehicle battery is connected to the device through the connecting ...

Problems solved by technology

[0006] Second, since the display is fixedly connected to the power-taking plug, and the display occupies a relatively large space, the display of the same size may not be suitable for cars with different dashboard streamline designs. It is easy to affect the use of space around the power interface, thereby affecting the driver's operation, for example, it is easy to block the push operation of the gear lever

[0007] Third, once the only one or two power-taking interfaces on the car are occupied by the display, it cannot provide power interfaces for other devices. Obviously, it is inefficient for the utilization of limited resources.
