Abstract

The utility model discloses a vehicle-mounted cigarette lighting seat with a voltage indicating function. The vehicle-mounted cigarette lighting seat with the voltage indicating function comprises a cigarette lighting seat shell, wherein the end part of the cigarette lighting seat shell is fixedly provided with a cigarette lighter plug; a power supply management module and a battery voltage display driving module are mounted in the cigarette lighting seat shell or the cigarette lighter plug; a liquid crystal display and a cigarette lighter socket are arranged in the cigarette lighting seat shell; the power supply management module the liquid crystal display, the cigarette lighter plug and the cigarette lighter socket are all electrically connected with the battery voltage display driving module; the power supply voltage value input from the vehicle-mounted cigarette lighter plug can be measured by the battery voltage display driving module, the power supply voltage value is the output voltage of the vehicle-mounted battery, and the voltage value is displayed by the liquid crystal display, so that people can monitor the voltage change of the battery in the vehicle conveniently at any time; the cigarette lighting seat shell is provided with the cigarette lighter socket, more convenience is provided for drivers to use vehicle-mounted electric appliances with the cigarette lighter plugs, so that the cigarette lighting seat does not occupy the standard-configured cigarette lighter hole in the vehicle relatively, and thus the vehicle-mounted cigarette lighting seat with the voltage indicating function is small in structure, saving in space and convenient to users.

Description

A kind of vehicle-mounted smoking base of deixis with voltage

Technical field

The utility model relates to the vehicle-mounted smoking base of a kind of smoking base, particularly a kind of deixis with voltage.

Background technology

Along with the development in epoch, the people who has vehicle is more and more, and the time of people's activity in car is also long, has therefore accelerated the exploitation of electrical appliance in car.And electrical appliance such as dust-collector for car in car, refrigerator for vehicle, in the car of mobile phone, Handless is equipped with, and all kinds of chargings etc., all can be used the Cigarette lighter jack supply power in car.Thereby the design people to have designed a not only structure that detects Cigarette lighter jack voltage small and exquisite, save space, and carry again Cigarette lighter jack, can make up the shortcoming that self takies vehicle-mounted cigarette lighter jack, meet numerous car owners' demand.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of vehicle-mounted smoking base of deixis with voltage.

The utility model solves the technical scheme that its technical matters adopts:

A kind of vehicle-mounted smoking base of deixis with voltage, it is characterized in that: comprise smoking base housing, and smoking base shell end is fixed with cigarette lighter plug, power management module, Battery voltage driver module are installed in smoking base housing or cigarette lighter plug, in smoking base housing, be provided with LCDs, Cigarette lighter jack, described power management module, LCDs, cigarette lighter plug and Cigarette lighter jack are all electrically connected with Battery voltage driver module.

In described smoking base housing, be provided with protection module, described cigarette lighter plug and Cigarette lighter jack are all electrically connected by protection module and Battery voltage driver module, and described power management module and protection module electric connection.

Described smoking base housing outer wall is provided with square box, and this square box has a display surface, and the central axis of this display surface and smoking base housing has angle, and described LCDs is positioned at this square box, and parallel with display surface.

The beneficial effects of the utility model are: the utility model comprises smoking base housing, and smoking base shell end is fixed with cigarette lighter plug, in smoking base housing or cigarette lighter plug, power management module is installed, Battery voltage driver module, in smoking base housing, be provided with LCDs, Cigarette lighter jack, described power management module, LCDs, cigarette lighter plug and Cigarette lighter jack are all electrically connected with Battery voltage driver module, by Battery voltage driver module, can record from the supply voltage value of Vehicular cigarette lighter plug input, this supply voltage value is the output voltage of vehicular power-bottle, LCDs demonstrates this magnitude of voltage, be convenient for people to monitor at any time the situation of change of Battery voltage in car, this smoking base housing is provided with the more convenient navigating mate of Cigarette lighter jack and uses the vehicle mounted electrical apparatus with cigarette lighter plug simultaneously, thereby this smoking base does not take the cigarette-lighter of standard configuration in car comparatively speaking, not only structure is small and exquisite, save space, also facilitated user.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structured flowchart of the present utility model;

Fig. 2 is block diagram of the present utility model.

The specific embodiment

Referring to figs. 1 through Fig. 2, the utility model discloses a kind of vehicle-mounted smoking base of deixis with voltage, the smoking base housing 4 that comprises tubular, and smoking base housing 4 ends are fixed with cigarette lighter plug 5, in smoking base housing 4 or cigarette lighter plug 5, power management module 1 is installed, Battery voltage driver module 2, in smoking base housing 4, be provided with LCDs 3, Cigarette lighter jack 6, by power taking in the Cigarette lighter jack of standard configuration in cigarette lighter plug 5 insertion cars, and the cigarette-lighter that a Cigarette lighter jack 6 can replace standard configuration in car that this Cigarette lighter seat takies is set again, thereby external mobile unit again, described power management module 1, LCDs 3, cigarette lighter plug 5 and Cigarette lighter jack 6 are all electrically connected with Battery voltage driver module 2, cigarette lighter plug 5 and Cigarette lighter jack 6 are the standard interface of the interior 12V power supply output of car now, thereby concrete structure does not describe in detail, in this example, power management module 1 has the function that realizes reduced output voltage, the low pressure that thereby the voltage of 12V in car could be changed into 5V is supplied with LCDs 3, in this example, power management module 1 has adopted DC-TO-DC source switch, Battery voltage driver module 2 has adopted MCU chip, above-mentioned parts are the conventional part in this area, at this, do not describe in detail.

For protective circuit; in described smoking base housing 4, be provided with protection module 7; described cigarette lighter plug 5 and Cigarette lighter jack 6 are all electrically connected by protection module 7 and Battery voltage driver module 2; and described power management module 1 is electrically connected with protection module 7, and protection module 7 can provide protection for whole circuit, during if any the situation of short circuit; protection module 7 can disconnect automatically; thereby prevent that whole circuit from being burnt, in this instantiation, protection module 7 is a wire fuse.

As shown in Figure 2, described smoking base housing 4 outer walls are provided with square box 8, and this square box 8 is obliquely installed, and described LCDs is positioned at this square box 8, and in said structure, LCDs 3 is also obliquely installed, thereby facilitate driver to bow, watches numeral.
