Technical field
The utility model relates to a kind of emergency switch indicating system, relates in particular to a kind of battery-driven car emergency switch indicating system.
Background technology
Emergency switch is the total control switch of power system of electric automobile, and the electrical source of power of battery-driven car provides power supply by this emergency switch to each vehicle arrangement.As shown in Figure 1, during normal vehicle operation, this emergency switch of chaufeur conducting K, electrical source of power provides power supply to each vehicle arrangement, and electrical motor rotates; When vehicle needed emergency brake, chaufeur disconnected emergency switch K, and electrical source of power stops to provide power supply to each vehicle arrangement, and electrical motor stops operating.In addition, in the vehicle maintenance and repair process, the maintainer can disconnect emergency switch K and reach absolute outage, thereby plays the effect of safety guard-safeguard.
Yet, at present on battery-driven car, chaufeur can only be judged by the height of observing the emergency switch handle conducting and the off-state of emergency switch, and this just causes the state of the frequent false judgment emergency switch of chaufeur, thereby the situation of a lot of inaccurate or maloperations has occured.
The utility model content
The utility model is intended to solve the technical matters that exists in the prior art, a kind of battery-driven car emergency switch indicating system has been proposed to special innovation, the employing indicator lamp has shown conducting and the off-state of emergency switch more significantly, for the operation of chaufeur is provided convenience.
In order to realize above-mentioned purpose of the present utility model, the utility model provides a kind of battery-driven car emergency switch indicating system, comprise electrical source of power, emergency switch (K) and vehicle arrangement, this electrical source of power is used for providing power supply by this emergency switch (K) to each vehicle arrangement, it is characterized in that: also comprise indicator lamp (L), one end of this electrical source of power connects the first end of this indicator lamp (L) by this emergency switch (K), the other end connects second end of this indicator lamp (L).The form of employing indicator lamp L has shown conducting and the off-state of emergency switch K more significantly, for the operation of chaufeur is provided convenience.
This indicator lamp (L) is in series with resistance (R).Indicator lamp L is in series with a resistance R, has reduced the electric current on the circuit, thereby has reduced the consumption of power on the indicator lamp L.
This indicator lamp (L) is selected the LED lamp of 10mW.This kind LED lamp low price and indicating effect are good, thereby have controlled the integral vehicle cost of vehicle.
This indicator lamp (L) is installed in emergency switch side or the display instrument, makes things convenient for chaufeur to check.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
The form of employing indicator lamp has shown conducting and the off-state of emergency switch more significantly, for the operation of chaufeur is provided convenience; Indicator lamp is in series with a resistance, has reduced the electric current on the circuit, thereby has reduced the consumption of power on the indicator lamp; Indicator lamp is selected the LED lamp of 10mW, and low price and indicating effect are good, thereby has controlled the integral vehicle cost of vehicle; Indicator lamp is installed in emergency switch side or the display instrument, makes things convenient for chaufeur to check.
Additional aspect of the present utility model and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present utility model.
Description of drawings
Above-mentioned and/or additional aspect of the present utility model and advantage are from obviously and easily understanding becoming the description of embodiment in conjunction with following accompanying drawing, wherein:
Fig. 1 is the fundamental diagram of emergency switch;
Fig. 2 is the fundamental diagram of this battery-driven car emergency switch indicating system.
Reference numeral: K is emergency switch, and R is resistance, and L is indicator lamp.
The specific embodiment
The below describes embodiment of the present utility model in detail, and the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, except other has regulation and restriction, need to prove, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be mechanical connection or electrical connection, also can be the connection of two element internals, can be directly to link to each other, and also can indirectly link to each other by intermediary, for the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
As shown in Figure 2, this battery-driven car emergency switch indicating system is comprised of electrical source of power, emergency switch K, resistance R, indicator lamp L and vehicle arrangement, and this electrical source of power provides power supply by emergency switch K to each vehicle arrangement; Resistance R and indicator lamp L series connection, an end of this electrical source of power is by the free end of emergency switch contact resistance R, and the other end connects the free end of indicator lamp L.During normal vehicle operation, this emergency switch of chaufeur conducting K, electrical source of power provides power supply to each vehicle arrangement, and indicator lamp L lights; Vehicle needs emergency brake or maintenance, when repairing, chaufeur disconnects emergency switch K, electrical source of power stops to provide power supply to each vehicle arrangement, and indicator lamp L extinguishes.Adopt the form of indicator lamp L to show more significantly conducting and the off-state of emergency switch K, for the operation of chaufeur is provided convenience, and indicator lamp L is in series with a resistance R, reduced the electric current on the circuit, thereby reduced the consumption of power on the indicator lamp L.
In the first embodiment of the present utility model, this indicator lamp L selects the LED lamp of 10mW (milliwatt), and this kind LED lamp low price and indicating effect are good, thereby has controlled the integral vehicle cost of vehicle.In addition, this resistance R is selected great resistance value, so that the consumption of power on the indicator lamp L has guaranteed that close to zero the flying power of car load is unaffected.
This indicator lamp L can be installed in any position that makes things convenient for chaufeur to check, in emergency switch side or display instrument.
In the description of this specification sheets, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
