[0026] Specifically, please refer to Figure 1 , it is the main structure schematic diagram of the safety airbag control device of the embodiment.
[0027] Airbag main controller 10 is used to judge whether vehicle encounters dangerous accident according to the sensing data of inertial sensor 11, when determining that vehicle encounters dangerous accident, the airbag is ejected to protect the life safety of driver and passenger.
[0028] To realize the controllability of safety airbag system, airbag main controller 10 includes rollover working condition response disable control end, when effective disable signal is connected to the rollover working condition response disable control end, airbag main controller 10 disables the ejection control function of airbag, to avoid safety airbag false ejection, which can be used in limit off-road, vehicle routine function test and other scenes. Electric connection seat 21 is connected in series on the control path of airbag main controller 10 including rollover working condition response disable control end, and detachably connected with electric connecting piece 22, and the dismounting operation is generally plug-in operation, compared with press type, touch type, dial type physical switch, plug-in operation is not easy to be false triggered, and the connection reliability of electric connection seat 21 and electric connecting piece 22 can be effectively improved.
[0029] After electric connecting piece 22 is inserted and mounted to electric connection seat 21, two ends of electric mounting seat 21 can be electrically connected, and then the signal source of disable signal is connected to airbag main controller 10 including rollover working condition response disable control end, and the disable signal is transmitted to airbag main controller 10, to disable the ejection control function of airbag.
[0030] The signal source of the disabling signal is generally a 12V DC power supply, and the specific electrical configuration inside the vehicle can be determined in practice. To avoid damage to the airbag main controller 10 caused by overload failure of the power supply, the electrical connecting piece 22 can be selected as a fuse. When the signal source of the disabling signal fails due to overload, the electrical connecting piece 22 can automatically disconnect to restore the ejection control function of the airbag main controller 10 on the airbag. When the signal source of the disabling signal fails due to overload, the source of the failure may be that the vehicle has encountered a safety accident. At this time, restoring the ejection control function of the airbag main controller 10 on the airbag can ensure safety.
[0031] Furthermore, the combination of the fuse and the electrical connecting piece 22 can improve the replaceability of the fuse and the replaceability of the system.
[0032] To facilitate the storage and management of the detachable electrical connecting piece 22, in an optional embodiment, the electrical connecting seat 21 includes parallelly arranged functional mounting positions and vacant mounting positions, and both are plugged and matched with the electrical connecting piece 22. The functional mounting positions are electrically connected in series on the control path of the rollover working condition response disabling control end of the airbag main controller 10, and the vacant mounting positions are electrically isolated from the airbag main controller 10. The electrical connecting piece 22 is detachably connected with the functional mounting positions and the vacant mounting positions of the electrical connecting seat 21, and can be electrically connected with the functional mounting positions.
[0033] When the airbag main controller 10 needs to be disabled, the electrical connecting piece 22 is inserted into the functional mounting position of the electrical connecting seat 21; in normal circumstances, the electrical connecting piece 22 can be removed from the functional mounting position of the electrical connecting seat 21 and inserted into the vacant mounting position of the electrical connecting seat 21 for storage, which can avoid the problem that the electrical connecting piece 22 is easily lost when kept separately.
[0034] In an optional embodiment, the electrical connection part of the electrical connecting piece 22 is arranged at the first end thereof, and both ends of the electrical connecting piece 22 are detachably connected with the electrical connecting seat 21. When the airbag main controller 10 needs to be disabled, the first end of the electrical connecting piece 22 is inserted into the electrical connecting seat 21; in normal circumstances, the second end of the electrical connecting piece 22 is inserted into the electrical connecting seat 21, which can reduce the size requirement of the electrical connecting seat 21 and the occupation of the installation space inside the vehicle.
[0035] To ensure the connection reliability of the electrical connecting piece 22 and the electrical connecting seat 21, in an optional embodiment, a paramagnetic medium plate (including iron, cobalt, nickel, etc.) is arranged in the electrical connecting seat 21, and a magnet is arranged in the electrical connecting piece 22, which can fix the electrical connecting piece 22 and the electrical connecting seat 21 through magnetic attraction.
[0036] In an alternative embodiment, the electrical connection seat 21 and the electrical connection piece 22 are both provided with paramagnetic medium (for example, cylinder, prism, etc.), one of the two paramagnetic medium is provided with an excitation winding, the excitation winding is in series with the electrical path of the corresponding one of the electrical connection seat 21 and the electrical connection piece 22, so that when the electrical connection seat 21 and the electrical connection piece 22 are electrically connected, the corresponding one of the paramagnetic medium can be configured into an electromagnet by the current in the circuit, and the electrical connection seat 21 and the electrical connection piece 22 are magnetically attracted and fixed.
[0037] In an alternative embodiment, the side wall of the electrical connection seat 21 and the electrical connection piece 22 is provided with a concave-convex matching locking structure, which is simple and effective. The locking structure can also be a spring, which can be reused as a contact electrode for electrically connecting the electrical connection seat 21 and the electrical connection piece 22.
[0038] A lock chain can also be provided between the electrical connection seat 21 and the electrical connection piece 22, and the electrical connection piece 22 can be hung in the vehicle through the lock chain after being taken out, avoiding loss. However, the electrical connection piece 22 fixed by the lock chain will swing, and the swing will be larger in extreme off-road conditions, causing the electrical connection piece 22 to collide with the structure in the vehicle and possibly damaging the electrical connection piece 22. The setting mode of the electrical connection piece 22 can be selected according to specific needs, for example, a groove can be provided on the periphery of the electrical connection seat 21, and a horizontal rod is arranged in the groove for installing the lock chain. The user can choose the setting mode of the electrical connection piece 22 according to their own preferences to improve the playability.
[0039] To facilitate confirmation of the disabled state of the airbag main controller 10, a disabled state indicator 30 is also provided in the embodiment, which is connected to the state signal output end of the airbag main controller 10, and can indicate the current state of the airbag main controller 10 through dimming, flashing, color, etc.
