Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
Embodiment one
Refer to Fig. 1, embodiments provide a kind of back-up lamp switch, comprising: lower house 12, upper shell 11, circuit card 2 and inductor 5.Wherein, lower house 12 has accommodating chamber 121, and accommodating chamber 121 is provided with opening, and upper shell 11 covers on opening; Circuit card 2 is arranged in accommodating chamber 121, circuit card 2 is provided with oscillator 31, and oscillator 31 is connected with upper shell 11 by support 21 usually with inductor 5 opposing circuit board 2, and inductor 5 is arranged on the gear level 4 in automobile.During concrete enforcement, support 21 is fixedly connected with upper shell 11, or support 21 and upper shell 11 are structure as a whole; Circuit card 2 is fixedly connected with support 21.
During work, be energized to oscillator 31, DC current is converted into exchange current by oscillator 31, exchange current generates an electromagnetic field, oscillator 31 is made to obtain vibration institute energy requirement, when Rotation With Changing pin 4, distance between oscillator 31 and inductor 5 changes, in the process that distance between oscillator 31 and inductor 5 diminishes gradually, the electromagnetic field that oscillator 31 produces makes inductor 5 generation current eddy current, the electric current eddy current that inductor 5 produces is by the energy absorbing of oscillator 31, thus cause the oscillation frequency of oscillator 31 to reduce, when gear level 4 is forwarded to reverse gear position time, nearest between oscillator 31 and inductor 5, the energy of oscillator 31 absorbs by electric current eddy current completely that produce in inductor 5, thus oscillator 31 is stopped oscillation.The signal of expression oscillation frequency is transferred to the control setup of automobile by oscillator 31 by circuit card 2, according to the oscillation frequency of oscillating current, control setup judges whether gear level 4 is positioned at position of reversing gear.Represent that gear level is positioned at position of reversing gear when oscillator 31 stops oscillation, control setup sends corresponding first control command makes backing-up lamp open; When other gears changed to by automobile by reversing gear time, gear level 4 rotates by position of reversing gear, make inductor 5 gradually away from oscillator 31, the impact of electric current eddy current on oscillator 31 in inductor 5 diminishes, the oscillation frequency of oscillator 31 strengthens gradually, and this timed unit sends corresponding second control command makes backing-up lamp close.
Do not contact between oscillator 31 with inductor 5 in the back-up lamp switch that the present embodiment provides, therefore can not produce electro spark because of contact thus cause back-up lamp switch ablation and lost efficacy, compared with contact back-up lamp switch of the prior art, the back-up lamp switch that the present embodiment provides decreases the problem generation that back-up lamp switch lost efficacy, thus improves the safety performance of automobile.
It is worth mentioning that, above-mentioned oscillator 31 can be LC oscillator (LC oscillator), RC oscillator (RC oscillator) or quartz oscillator, and above-mentioned inductor 5 is made of metal.
While above-mentioned back-up lamp switch work, control setup will judge the oscillation frequency of the signal indication that oscillator 31 feeds back, then judge whether gear level 4 is in position of reversing gear, and then just can send control command and control backing-up lamp and open or close, that is control setup is opened or close from being received signal that oscillator 31 spreads out of need certain reaction time to controlling backing-up lamp.In order to improve the safety performance of automobile further, in a preferred embodiment, circuit card 2 is also provided with switch converter 32, switch converter 32 is connected with oscillator 31 signal, the oscillation frequency of oscillator 31 is converted to high level and low level two kinds of signals by switch converter 32, the signal that switch converter 32 exports passes to control setup by circuit card 2, and control setup sends corresponding first instruction or the second instruction controls backing-up lamp unlatching or closes.Such as, when the oscillation frequency of oscillator 31 is zero, switch converter 32 output low level, this timed unit sends the first control command makes backing-up lamp open; When the oscillation frequency of oscillator 31 is non-vanishing, switch converter 32 exports high level, and this timed unit sends the second control command makes backing-up lamp close.Design like this, the signal that oscillator 31 exports is converted to high level and low level two kinds via switch converter 32, and high level represents that gear level 4 is not in position of reversing gear, and need close backing-up lamp; Low level represents that gear level 4 is in position of reversing gear, and need open backing-up lamp.Therefore, the easier controlled device of signal that oscillator 31 feeds back to control setup via switch converter 32 judges, thus make control setup shorter to the reaction time controlled needed for backing-up lamp unlatching or closedown from receiving signal, and then further increase the safety performance of automobile.
In order to the easier controlled device identification of the signal making switch converter 32 export, preferably, circuit card 2 is also provided with signal amplifier 33, signal amplifier 33 is connected with switch converter 32 signal, signal that switch converter 32 exports by signal amplifier 33 amplifies and by the signal feedback after amplifying to control setup, the easier controlled device identification of signal after amplification, thus the speed of the signal controlled device identification that oscillator 31 is exported accelerates.
Be energized for ease of giving oscillator 31, and the signal feedback being convenient to oscillator 31 to produce is to control setup, refer to Fig. 1 and Fig. 2, in a preferred embodiment, upper shell 11 is provided with connector 6, one end of the power supply stitch 61 of connector 6 is inserted in the power end of circuit card 2, and the other end is inserted in the power end of automobile; One end of the ground pin 62 of connector 6 is inserted in the ground terminal of circuit card 2, and the other end is inserted in the ground terminal of automobile; One end of the signal output stitch 63 of connector 6 is inserted in the signal output part of circuit card 2, and the other end is inserted in the signal receiving end of control setup.Be energized to oscillator 31 by power supply stitch 61, the signal feedback spread out of by oscillator 31 by signal output stitch 63, to control setup, is made control setup perform according to the signal that oscillator 31 spreads out of and sends corresponding control command.
In order to avoid circuit card 2 uses for a long time by dust or aqueous corrosion, in a preferred embodiment, be filled with epoxide-resin glue in accommodating chamber 121, circuit card 2 is placed in epoxide-resin glue.Whole accommodating chamber 121 is filled full by epoxide-resin glue, is enveloped by circuit card 2.When being covered after on the opening of lower house 12 by upper shell 11, accommodating chamber 121 becomes an airtight space, prevents dust and water to enter accommodating chamber 121, thus avoids circuit card 2 and be corroded.
