Detailed Description
In order that the description may be clearly understood by those skilled in the art, it is to be understood that the term "electrically coupled" as used herein below means that an electrical signal can be transmitted between two objects that are electrically coupled. The manner of transmitting the electronic signals may be wired or wireless, and the direction of transmitting the electronic signals may be unidirectional or bidirectional, unless otherwise defined.
Referring to fig. 1, the present utility model is directed to detecting whether the seat belt buckle 100 shown in fig. 1 is properly inserted into the seat belt fixing device 110 so that the seat belt 130 can be fastened with the seat belt fixing device 110 through the seat belt buckle 100.
Referring to fig. 2, a system block diagram of a seat belt buckle position detection system according to an embodiment of the utility model is shown. As shown in fig. 2, the seat belt buckle position detection system 20 in the present embodiment mainly includes a magnetic body 205 disposed on the seat belt buckle 200, a magnetic field detection unit 212 and a wireless communication unit 214 disposed on the seat belt fixing device 210, and a control device 220 for determining whether the position of the seat belt buckle 200 meets the requirement. In the seat belt buckle 200, the magnetic body 205 may be any body capable of generating a magnetic field, such as a general permanent magnet. In order to determine the position of the seat belt buckle 200 well, it is preferable that the magnetic field generated by the magnetic body 205 is not detected by the magnetic field detecting unit 212 when the seat belt buckle 200 is not yet inserted into the seat belt fixing device 210; on the other hand, when the seat belt buckle 200 is inserted and fastened to the seat belt fixing device 210, the distance between the magnetic object 205 and the magnetic field detection unit 212 must be sufficiently close so that the magnetic field detection unit 212 can detect the magnetic field generated from the magnetic object 205.
In the seatbelt fixing device 210, the magnetic field detecting unit 212 is disposed to be electrically coupled to the wireless communication unit 214. As shown in fig. 2, when the magnetic field generated from the magnetic object 205 is detected, the magnetic field detecting unit 212 correspondingly generates a switching signal T1 to indicate that the magnetic field has been detected, and further transmits the switching signal T1 to the wireless communication unit 214. After receiving the switching signal T1, the wireless communication unit 214 generates a corresponding acknowledgement signal M1 according to the received switching signal T1, and transmits the acknowledgement signal M1 in a wireless transmission manner. The wireless communication unit 225 in the control device 220 employs the same communication protocol as the wireless communication unit 214, e.g. the bluetooth communication protocol, adapted to receive the acknowledgement signal M1 it generates from the wireless communication unit 214. The confirmation signal M1 received by the wireless communication unit 225 is transmitted to the control device 220, and the control device 220 determines whether the seat belt is fastened to the seat belt fixing device 210 via the seat belt fastener 200 according to the received confirmation signal M1, and generates a response according to the determination result.
The response generated by the control device 220 after the determination according to the confirmation signal M1 may also be different in different application environments. For example, when the control device 220 is a central control computer of the vehicle, the control device 220 may allow the vehicle to move only when the seat belt buckle 200 is fastened in the seat belt fixing device 210, and prohibit the vehicle from moving at other times; in contrast, when the control device 220 is an additional expansion module, the control device 220 may only provide a limited warning, such as a warning light signal or a warning sound, when the seat belt buckle 200 has not been fastened in the seat belt fastening device 210, and may cease to provide a warning after the seat belt buckle 200 has been fastened in the seat belt fastening device 210.
Referring to fig. 3, a system block diagram of a seat belt buckle position detection system according to another embodiment of the utility model is shown. In the present embodiment, the seat belt buckle position detecting system 30 includes a magnetic body 305 disposed on the seat belt buckle 300, a magnetic field detecting unit 312 disposed on the seat belt fixing device 310, a wireless communication unit 314 and a power supply device 316, a control device 320 for determining whether the position of the seat belt buckle 300 meets the requirement, and a notification device for providing audible or visual identification information.
Similar to the embodiment shown in fig. 2, the magnetic object 305 may be any object capable of generating a magnetic field. In order to determine the position of the seat belt buckle 300, that is, whether the seat belt buckle 300 has been inserted into the seat belt fixing device 310, it is preferable that the magnetic field detection unit 312 detects the magnetic field generated by the magnetic object 305 only when the seat belt buckle 300 is completely inserted into the seat belt fixing device 310.
In the embodiment shown in fig. 3, the electrical coupling and operational relationship between the magnetic field detection unit 312 and the wireless communication unit 314 provided on the seatbelt anchor 310 are similar to those of the embodiment shown in fig. 2, and will not be repeated here. In addition to the magnetic field detection unit 312 and the wireless communication unit 314, a power supply device 316 is further provided on the seatbelt fixing device 310. In the present embodiment, the power supply device 316 is electrically coupled to the wireless communication unit 314 to supply the power required for the operation of the wireless communication unit 314. It should be noted that, although the wireless communication unit may be designed to operate in a manner of generating power in response to the magnetic field change caused by the movement of the magnetic object (e.g. the wireless communication unit 214 may be regarded as a product designed in this way), less power is available in this manner, and it may not be possible to support the wireless communication unit to perform the wireless signal transmission over a longer distance, so the power supply device 316 is used to supply the power required for the operation of the wireless communication unit 314 to obtain the wireless signal transmission distance over a longer distance. In a typical situation, when the wireless communication unit 314 is constructed with a bluetooth communication module, a small button cell may be required to maintain its operation for years, so that the additional power expended on wireless communication to implement the present utility model is minimal.
Please refer to fig. 3 again. The wireless communication unit 325 in the embodiment shown in fig. 3 is also used to receive acknowledgement signals generated by the wireless communication unit 314 and to communicate the received acknowledgement signals to the control device 320. Next, the control device 320 determines whether the seat belt is fastened in the seat belt fixing device 310 via the seat belt buckle 300 according to the received confirmation signal, and sends out a notification signal S1 according to the determination result. Further, as shown in fig. 3, the notification device 330 of the seat belt buckle position detecting system 30 is electrically coupled to the control device 320 to receive the notification signal S1 sent by the control device 320. After receiving the notification signal S1, the notification device 330 may send out corresponding notification information according to the request of the notification signal S1. Here, the notification device 330 may be various audio-visual or light signal devices fixedly connected to the carrier, or may be a mobile device suitable for carrying everywhere, such as a smart phone or a smart watch, and the notification device 330 may correspondingly adopt a suitable communication interface when sending the notification signal S1.
The improvement of the utility model lies in the use of hardware devices such as a magnetic object, a magnetic field detection unit, a first wireless communication unit, a second wireless communication unit, a power supply device and the like, and the coupling relation among the devices, and the control performed by the control device can be realized by the prior art.
In summary, the position detecting system for the seat belt buckle provided by the utility model can enable the vehicle to obtain the capability of detecting whether the seat belt is well tied or not under the condition that no wiring between the control device and the seat belt fixing device is needed. In addition, experiments prove that the extra consumption of power required by adopting wireless communication is extremely low. Therefore, the novel technology is simple and feasible, and can be applied to various carriers with the capability of being newly added.
