It connects, the heating controller is connect with heating implements；
The temperature collection unit is for acquiring ambient temperature information and temperature data being sent to heating controller
In, the heating controller controls heating implements according to preset heating starting temperature threshold and starts work, the heating
Executing agency is arranged on the decorative cover medial surface of air bag.
The heating controller is connect with air bag temperature collecting cell, and the air bag temperature collecting cell is for detecting decorative cover
Interior environment temperature, the heating controller stop temperature threshold control heating mechanism according to heating and stop working.
The heating implements are resistance wire, power control switch, and the power control switch and heating controller connect
It connects, the computer heating control switch is serially connected between resistance wire and power supply.
The resistance wire is arranged on the inner sidewall of decorative cover.
The decorative cover forms closed cavity, and gas generator, the airbag of air bag are arranged in closed cavity.
The heating controller connects heating work indicator light, and the heating work indicator light is used to indicate air bag and adds
Warm status.
The heating work indicator light is arranged on instrument board.
Utility model has the advantages that being formed when environment temperature drops to preset value to the decorative cover of air bag
Cavity is heated, so that the gas generator temperature being arranged in cavity increases, reduces temperature to lower than the normal work of air bag
The influence of work；Indicator light can serve to indicate that heating work state, understand air bag heating state for user.
Detailed description of the invention
Below to each width attached drawing of the utility model specification expression content and figure in label be briefly described:
Fig. 1 is the utility model heating device schematic illustration
Specific embodiment
Specific embodiment of the present utility model is made into one by the description to optimum embodiment below against attached drawing
Step detailed description.
In order to enable driver airbag DAB its property (at especially low-down temperature) under different environment temperatures
It can also obtain stablizing performance, the utility model devises a safe air bag for vehicle driver intelligent heater, so that DAB
Module is in the temperature range of a relatively safety and stability always, reduces negative effect of the environment temperature to its performance.Pass through
Environment temperature is monitored, and Resistant heating control is carried out using special controller, so that entire DAB module is located for a long time
Under relatively stationary temperature, the decorative cover of DAB module uses the cavity structure of relative closure, pre-buried on its surrounding cavity wall
Resistance wire is heated using Weak current, and DAB module is that be set to chamber intracorporal；When the temperature of DAB inside modules is higher than
Stopping heating being automatically cut off the power after certain range, to realize the heating for airbag inflated part, reduce temperature
It spends for gas generation and the influence of pressure, specific as follows:
As shown in Figure 1, in the present embodiment air bag heating device include temperature collection unit, heating controller,
Heating implements, temperature collection unit are connect with heating controller, and heating controller is connect with heating implements；Ring
Border temperature collecting cell is for acquiring ambient temperature information and temperature data being sent in heating controller, heating controller root
Start work according to preset heating starting temperature threshold control heating implements, air bag is arranged in heating implements
In decorative cover.20 DEG C such as are set by temperature threshold when starting, by temperature collecting cell temperature collection data, when temperature is lower than
At 20 DEG C, heating implements is controlled by heating controller, the decorative cover of air bag is heated, so that in decorative cover
Environment temperature increases.Thermistor principle can be used to realize in temperature collecting cell.
Air bag includes gas generator, air bag, sensor etc., and air bag and gas generator setting are formed by decorative cover
Relative closure cavity structure in, after crash sensor collects collision alarm control detonating primer work so that gas
Body propellant generates gas, inflates for air bag, and then completes the starting of air bag, and air bag flicks decorative cover to for for providing guarantor
Shield.It is influenced to reduce temperature for gas generation and pressure etc., decorative cover is heated, so that decorative cover composition is close
Closed chamber vivo environment temperature increases, and then realizes the heating for gas generator, reduces low temperature for the shadow of air bag
It rings.
Heating implements preferably include resistance wire, power control switch, and power control switch and heating controller connect
The control signal to receive heating controller is connect, computer heating control switch is serially connected between resistance wire and power supply.Resistive heater
It is arranged on the inner sidewall of decorative cover, is realized by way of resistance wire pre-buried on surrounding cavity wall, resistance wire is evenly distributed on
Cavity surrounding can be evenly heated entire cavity, and then realize the heating for gas generator in the cavity is arranged.
When heating controller needs to start heating, heating controller issues control signal to computer heating control and switchs, so that computer heating control
It closes the switch, the current supply circuit between power supply and resistance wire is connected to, resistance wire fever；When controlling computer heating control switch disconnection,
Current supply circuit disconnects, and resistance wire stops heating.Power supply makes resistance wire generate heat by the way of exporting Weak current.Computer heating control
Switch can be realized using electric-controlled switch such as relay etc..
Air bag temperature collecting cell is set in the cavity that decorative cover is formed, for detecting environment temperature in decorative cover, with heating
Controller connection, heating controller stop temperature threshold control heating mechanism according to heating and stop working.Preset stopping temperature pair
According to gas required temperature occurs for the threshold value answered specifically to set.When air bag temperature collecting cell collects decorative cover formation
When inside cavity environment temperature reaches temperature threshold, control heating implements stop heating, and heating terminates.
Air bag heating lamp is set on instrument board, and heating work indicator light is used to indicate air bag heating shape
State, heating lamp are connect with heating controller, for the control signal light on and off according to heating controller.When starting heating mechanism
When, control LED heating lamp is bright, otherwise goes out, and can be convenient driver in this way and understands air bag heating device working condition.
The utility model forms cavity in the decorative cover of air bag and is heated, so that the intracorporal gas generator of chamber
Temperature increases, and so as to keep the environment temperature of gas generator generation gas to be maintained at the range of relative temperature, reduces temperature
Spend the low influence that gas occurs.
