The utility model content
The purpose of this utility model provides a kind of automotive seat heating module safety control, can in time detect power supply short circuit, when an end that heating cushion occurs and power supply short circuit, can control by relay and make heating cushion can't continue heating, thereby increase the security of system.
For achieving the above object, the utility model provides a kind of automotive seat heating module safety control, comprises controller, and described controller one end connects power supply, and the other end is connected with heating cushion; Described controller comprises control module, heating cushion driver module, fault collection circuit and relay, the input end of wherein said heating cushion driver module is connected to an output terminal of power supply and control module, and the output terminal of described heating cushion driver module is connected to the input end of heating cushion and fault collection circuit; The input end of described control module is connected to the output terminal of described fault collection circuit, and another output terminal of described control module is connected to relay; One end of described heating cushion is by the contact ground connection of described relay.
Preferably, described fault collection circuit monitor in real time heating cushion whether with power supply short circuit, and this fault collection signal sent to described control module, described control module is controlled the suction of described relay according to this signal and or is disconnected.
Preferably, described fault collection circuit comprises two resistance, wherein an end of first resistance is connected between the output terminal and described heating cushion of described heating cushion driver module, the other end of first resistance is connected to an end of second resistance, the other end ground connection of described second resistance, an output terminal of described control module is connected between two resistance.
In the utility model, described control module is controlled contact adhesive or the disconnection of described relay by high-low level, and described control module is sent control signal, by described heating cushion driver module heating cushion is heated.If the fault collection circuit monitoring to heating cushion and power supply short circuit, is then controlled the contact disconnection of described relay, thereby can't be proceeded heating to heating cushion by control module.
The utility model beneficial effect: the utility model is by arranging fault collection circuit and relay, by the fault collection circuit monitor in real time the power supply short circuit fault and by relay inhale and or disconnect, when taking place, fault passes through in time to detect power supply short circuit and block system relay, prevent from heating cushion is continued heating, strengthened the security of system.The utility model is simple in structure, and is practical and convenient.
Description of drawings
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 is the utility model circuit theory diagrams;
Among the figure: U1 is control module, and U2 is the heating cushion driver module, and R1 is first resistance, and R2 is second resistance, and LOAD1 is heating cushion, and RL1 is relay, and VBAT is power supply, and GND is ground.
Embodiment
Below in conjunction with specific embodiment the utility model is elaborated.Following examples will help those skilled in the art further to understand the utility model, but not limit the utility model in any form.
As shown in Figure 1, present embodiment provides a kind of automotive seat heating module safety control, comprise controller, described controller comprises control module U1, heating cushion driver module U2, first resistance R 1, second resistance R 2 and relay R L1, the input end of described heating cushion driver module U1 is connected to the output terminal of power supply VBAT and control module U1, and the output terminal of described heating cushion driver module U1 is connected to heating cushion LOAD1 and first resistance R 1, second resistance R 2; One end of first resistance R 1 is connected between the output terminal and described heating cushion of described heating cushion driver module U2, the other end of first resistance R 1 is connected to an end of second resistance R 2, the other end ground connection of described second resistance R 2, the output terminal of described control module U1 is connected between first resistance R 1, second resistance R 2.
In the present embodiment, described heating cushion driver module U2 one end connects power supply VBAT, and the other end connects the end A of heating cushion LOAD1, and the other end B of heating cushion LOAD1 is by relay R L1 ground connection.
In the specific implementation, switch on when described heating cushion driver module U2 connects power supply VBAT, when starting heating function, described control module U1 sends high level, make the contact adhesive of described relay R L1, the B end of heating cushion is by the contact ground connection GND of described relay R L1; Described control module U1 sends control signal then, heats by the heating cushion LOAD1 of described heating cushion driver module U2.
If described control module U1 stops to add thermal output, still can detect voltage signal by first resistance R 1 and second resistance R 2, can judge that then the A end of heating cushion LOAD1 takes place the power supply short circuit situation.This moment, described control module U1 sent low level, and the contact of controlling described relay R L1 discharges, and the B end of heating cushion is disconnected with ground.Thereby prevent from continuing the heating to heating cushion LOAD1, cause client's discomfort and initiation fire.
The utility model is by arranging fault collection circuit and relay in the controller increase, by the fault collection circuit monitor in real time the power supply short circuit fault and by relay inhale and or discharge, prevent from heating cushion is continued heating, strengthened the security of system.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
