Abstract
The utility model discloses and aims at providing a heating switch for an automobile seat, which belongs to a switch for a stage-by-stage signal control circuit and has the characteristics of simple structure and reliable operation. The heating switch is composed of a button (1), a shell body (2) and a circuit board (3). The stage-by-stage signal control circuit arranged on the circuit board at the inner part of the switch adopts three-stage-by-stage control and is composed of a micro switch (4), a control chip unit (5), a relay JI (6) and a relay JII (11) on the circuit board. The control chip unit (5) outputs a signal by recognizing the number of times of the button (1) in pressing the micro switch (4), so as to control the switching in or off of the relay JI (6) and the relay JII (11), thereby carrying out heating load control on the automobile seat. The heating switch can be widely applied to various automobiles.
Description
Technical field: the utility model relates to a kind of back seat heater switch that is provided with the control circuit step by step of control chip signal output, particularly a kind of automotive seat heater switch.
Background technology: the general mechanical switchs that adopt of automotive seat heater switch more, this type construction of switch is comparatively complicated, easily breaks down; Automotive seat is added the general methods that directly connect heating load that adopt of thermal control more, and big electric current lost efficacy switch easily because of need directly bear.
Summary of the invention: the purpose of this utility model is to provide a kind of automotive seat heater switch, utilizes this switch can realize the control step by step that seat on the automobile is heated; Switch of the present utility model low-heat, the high hot state of two kinds of different colours light representations seats heating of light-emitting diode; The utility model is a kind of automotive seat heater switch that includes circuit board, and sensitive switch, control chip unit, relay are arranged on its circuit board; Its control circuit is divided into three grades of controls step by step, and button is whenever pushed sensitive switch once on the switch, and output corresponding signal in control chip unit is switched on or switched off relay (JI, JII), reaches the purpose that the automotive seat heating load is controlled.
Formation of the present utility model: be made up of button, housing and circuit board, button is installed in the top of housing, and high low-heat status indicator lamp is arranged on button, mounting circuit boards in housing, and circuit board is provided with switching signal control circuit step by step, is divided into three grades of controls step by step; This circuit is made of sensitive switch, control chip unit, relay J I, relay J II on the circuit board; Wherein the control chip unit is connected on plug receptacle I and is connected with power supply IG, the control chip unit is connected with relay J I by plug receptacle II and is connected with the low heat load of seat heating, and the control chip unit is connected with relay J II by plug receptacle III and is connected with seat heating high heat load.
Through 2 relay J I, JII the power output of the heater in the seat is carried out three grades of stepping controls with a sensitive switch; Three grades of steppings control comprise close, low-heat, high heat circulate successively.
The seat heater switch is hot with low-heat, the height of 2 kinds of different colours light representations seat heating of light-emitting diode.
Compare with the existing machinery configuration switches, the utility model is formed signal control circuit step by step by the sensitive switch on the circuit board, control chip unit, relay (J1, J2), not only can avoid on the switch electric contact directly to bear big electric current and damage, its structure is also simple than mechanical switch simultaneously, and rate of breakdown is low.
Description of drawings: Fig. 1 is a structural representation, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is an electrical schematic diagram.
1. buttons among the figure, 2. housing, 3. circuit board, 4. sensitive switch, 5. control chip unit, 6. relay J I, 7. plug receptacle II, 8. the low heat load of seat heating, 9. seat heating high heat load, 10. plug receptacle III, 11. relay J II, 12. plug receptacle I, 13. power supply IG, 14. high low-heat status indicator lamps.
In embodiment: Fig. 1～3, button 1 is installed in the top of housing 2, and high low-heat status indicator lamp 14 is arranged on button 1, and circuit board 3 is installed in the housing 2, links to each other with external heated load, power supply etc. by the plug receptacle that is located on the housing.Circuit board 3 is provided with signal control circuit step by step, be divided into three grades of controls step by step, this circuit is made of the sensitive switch on the circuit board 4, control chip unit 5, relay J I6, relay J II11, wherein control chip unit 5 is connected on plug receptacle I12 and is connected with power supply IG13, the control chip unit is connected with relay J I6 by plug receptacle II7 and is connected with the low heat load 8 of seat heating, and the control chip unit is connected with relay J II11 by plug receptacle III10 and is connected with seat heating high heat load 9.Button 1 is pushed sensitive switch 4 once, and the control chip element output signal makes relay J I6 adhesive, connects the low heating load 8 of seat; Button 1 is pushed sensitive switch 4 secondaries, and the control chip element output signal makes relay J II11 adhesive, and relay J I6 disconnects, and connects seat height heating load 9; Button press sensitive switch three times, the control chip element output signal disconnects relay J I6, JII11 simultaneously, cuts off low, the high heating load power supply of seat, and so forth circulation.
