Among them, the anti-collision device 20 has an airbag 211, an inflator 221 and an exhaust device (not shown in the figure), and is fixed to the rear side of the vehicle body through a fastener (not shown in the figure). When the fastener (not shown in the figure) (shown in the figure) is unlocked, the anti-collision device 20 will detach from the rear side of the vehicle body and fall to the road. The inflator 221 will inflate the airbag 211. Once a secondary collision occurs, the airbag 211 can buffer to reduce the collision. Effect, wherein the inflation method of the inflator 221 may be to use carbon dioxide to quickly inflate with a chemical reaction, but this inflation method should not be understood to be limited to the embodiment stated here.

The exhaust device (not shown in the figure) can be a deflation valve. However, this exhaust device should not be construed as being limited to the embodiments set forth herein. The speed measuring module (not shown in the picture) is used to detect the speed of the oncoming vehicle on the rear side of the car body. The speed measuring module can use an image recognition device to detect the speed of the oncoming vehicle from behind, or it can also measure the speed through radar. However, This speed measurement module should not be construed as being limited to the embodiments set forth herein.
驅動模組40是設置於防撞裝置20上，並且可以配置有動力裝置411及測距裝置421，其中，動力裝置411用來驅動防撞裝置20進行位移，使防撞裝置20能自動行走至適當位置作為警示標誌，藉以達到降低人員擺放警示標誌風險之目的。而測距裝置421，則是用來偵測防撞裝置20位移後與車體後側的距離，其中，測距裝置421可以是雷射測距儀。控制模組50具有安全距離表511、後車速度表(未顯示於圖中)及控制器521，安全距離表511提供行駛道路所對應的警示距離，後車速度表提供後方來車的速度所對應的提醒距離，而本發明中的安全距離表511及後車速度表皆可進行調整，並設置對應不同道路的警示距離及對應不同速度的提醒距離，使用者也可利用終端裝置遠端通信聯繫控制 模組50修改安全距離表511及後車速度表。通訊模組60用以連接防撞裝置20、測速模組、驅動模組40及控制模組50。 The driving module 40 is installed on the anti-collision device 20 and can be configured with a power device 411 and a distance measuring device 421. The power device 411 is used to drive the anti-collision device 20 to displace, so that the anti-collision device 20 can automatically move to Use appropriate locations as warning signs to reduce the risk of personnel placing warning signs. The distance measuring device 421 is used to detect the distance between the anti-collision device 20 and the rear side of the vehicle body after the displacement. The distance measuring device 421 may be a laser range finder. The control module 50 has a safety distance table 511, a following vehicle speedometer (not shown in the figure) and a controller 521. The safety distance table 511 provides the warning distance corresponding to the driving road, and the following vehicle speedometer provides the speed of the vehicle coming from behind. The corresponding reminder distance, and the safety distance table 511 and the speedometer of the following vehicle in the present invention can be adjusted, and warning distances corresponding to different roads and reminder distances corresponding to different speeds can be set. The user can also use the terminal device for remote communication. contact control Module 50 modifies the safety distance table 511 and the speed table of the following vehicle. The communication module 60 is used to connect the anti-collision device 20 , the speed measuring module, the driving module 40 and the control module 50 .
值得一提的是，在一般狀況下，安全距離表511的警示距離會隨著行駛道路的速限越高，警示距離越長，而後車速度表的提醒距離會隨著後方來車的速度越快，提醒距離越長，以提供後方來車充足的反應時間避免追撞。另外，值得注意的是，當安全距離表511的警示距離大於後車速度表的提醒距離時，將以安全距離表511的警示距離為主要的防撞裝置20移動距離標準，當安全距離表511的警示距離小於後車速度表的提醒距離時，將以後車速度表的提醒距離為主要的防撞裝置20移動距離標準。 It is worth mentioning that under normal circumstances, the warning distance of the safety distance meter 511 will be longer as the speed limit of the driving road is higher, and the warning distance of the speedometer of the following car will be longer as the speed of the car coming from behind. The faster, the longer the warning distance is to provide sufficient reaction time for vehicles coming from behind to avoid collisions. In addition, it is worth noting that when the warning distance of the safety distance table 511 is greater than the warning distance of the speedometer of the following vehicle, the warning distance of the safety distance table 511 will be used as the main moving distance standard of the anti-collision device 20. When the safety distance table 511 When the warning distance is less than the reminder distance of the speedometer of the following vehicle, the reminder distance of the speedometer of the following vehicle will be the main moving distance standard of the anti-collision device 20.

Among them, the anti-collision device 20 has an airbag 211 and an inflator 221, and is fixed to the rear side of the vehicle body through a fastener (not shown in the figure). When the fastener (not shown in the figure) is unlocked, the anti-collision device 20 will break away from the rear side of the vehicle body and fall to the road. The inflator 221 will inflate the airbag 211. Once a secondary collision occurs, the airbag 211 can provide buffering to achieve a collision reduction effect. The driving module 40 is arranged on the anti-collision device 20 and has a power device 411 and a distance measuring device 421. The power device 411 is used to drive the anti-collision device 20 to displace, so that the anti-collision device 20 can automatically move to an appropriate position. Warning signs are used to reduce the risk of personnel placing warning signs. The distance measuring device 421 is used to detect the distance between the anti-collision device 20 and the rear side of the vehicle body after displacement. The control module 50 has a safety distance table 511, a controller 521, a sensor (not shown in the figure) and an alarm device (not shown in the figure). The safety distance table 511 provides a warning distance corresponding to the driving road, and the sensor ( (not shown in the picture) is installed on the outside of the car body (not shown in the picture). When the sensor senses an external force hitting the car body, it notifies the alarm device (not shown in the picture), and the alarm device emits an alarm sound to remind the driver. A car accident may occur. After the alarm sounds for a specific period of time, the controller 521 of the control module 50 controls the lock to unlock, causing the anti-collision device 20 to detach from the rear side of the vehicle body and fall. On the road surface, the specific time of the alarm sound can be a freely set length of time, for example, it can be 10 seconds to 15 seconds, but the specific time of the alarm sound should not be understood to be limited to the embodiment stated here. Then the control module 50 controls the driving module 40 to drive the anti-collision device 20 to move according to the warning distance provided by the safety distance table 511, and the control module 50 controls the distance measuring device 421 to measure the distance the anti-collision device 20 moves. 50 determines whether the distance meets the warning distance provided by the safety distance table 511, and the airbag 211 of the anti-collision device 20 is inflated by the inflator 221 to achieve anti-collision and collision reduction effects. In addition, it is worth mentioning that within a specific period of time when the alarm device sounds the alarm, the driver can judge the situation on the scene. If the situation is minor and the vehicle can be moved or the sensor misjudges, the driver can directly cancel the alarm sound of the alarm device and stop the safety. The subsequent operation process of the anti-collision system.
