In one embodiment, the control circuit 10 may output an alarm signal to the alarm circuit 14 and a lock signal to the door lock 16 according to the detection result of the detection circuit 12. The door lock described herein is, for example, a door lock of a vehicle.

In one embodiment, the detection circuit 12 is, for example, a distance detection circuit for detecting the movement of a vehicle or an object. Further, the distance detection circuit is, for example, a radar ranging circuit, an infrared ranging circuit, or an ultrasonic ranging circuit.

In one embodiment, the warning circuit 14 may be one or a combination of a light output circuit 141 that emits a light warning signal or a sound output circuit 142 that emits a sound warning signal, for example. The light output circuit 141 is, for example, a mirror LED turn signal circuit of a vehicle. The sound output circuit 142 is one or any combination of sound emitting devices such as a buzzer, a buzzer piece, a horn, and the like. However, the present invention is not limited to the arrangement of the detection circuit 12 and the warning circuit 14.

In one embodiment, the control circuit 10 is, for example, one or any combination of an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or a system on a chip (SOC). However, the present invention is not limited to the above examples.

In one embodiment, when the control circuit 10 knows that there is a vehicle or an object approaching the rear of the vehicle through the detection circuit 12, the control circuit 10 outputs a locking signal to the door lock 16, so that the door lock 16 can lock the door of the vehicle according to the locking signal, for example, a door lock center locking signal. Furthermore, the control circuit 10 can further output a warning signal to the warning circuit 14, so that the warning circuit 14 can emit a light warning signal or a sound warning signal accordingly. When the control circuit 10 does not know that the vehicle or the object is approaching the rear of the vehicle through the detection circuit 12, the control circuit 10 does not output the locking signal and the warning signal.

Referring to fig. 2, fig. 2 is a schematic view illustrating a safety detection device disposed on a vehicle according to an embodiment of the present invention. When the safety detecting device 1 of the present embodiment is applied to the vehicle 3, the control circuit 10 and the detecting circuit 12 are respectively disposed at appropriate positions of the vehicle body 30 according to different functional designs. For example, the detection circuit 12 may be provided at the rear bumper 32 of the vehicle body 30, thereby detecting the moving condition of the vehicle or the object behind the vehicle body 30. The control circuit 10 is provided in a vehicle interior space of the vehicle body 30, and may be provided near a driver's seat, for example. The warning circuit 14 is provided in a suitable position for warning the user, for example, in the in-vehicle space or the out-vehicle space of the vehicle body 30.

For example, the number of the detection circuits 12 may be plural, and the detection circuits 12 may be provided at each of the left and right positions of the rear bumper 32. Therefore, the detection circuit 12 disposed on the left side of the rear bumper 32 can be used to detect the movement of other vehicles or objects in the left rear of the vehicle. The detection circuit 12 provided on the right side of the rear bumper 32 can be used to detect the movement of another vehicle or object behind the right side of the vehicle. However, the present invention is not limited to this, and the arrangement positions and the number of the detection circuits 12 may be flexibly arranged according to the requirements.

The light output circuit 141 is, for example, a mirror LED turn signal circuit provided outside the vehicle 3. When the detection circuit 12 detects that there is a vehicle coming behind the vehicle, the detection circuit 12 transmits the detection result to the control circuit 10, and the control circuit 10 controls the light output circuit 141 to output a light warning signal to warn the user not to open the vehicle door. The sound output circuit 142 is provided inside the vehicle 3, for example, and when the detection circuit 12 detects that there is an incoming call behind the vehicle, the detection circuit 12 transmits the detection result to the control circuit 10. The control circuit 10 can control the light output circuit 141 to output the light warning signal, and also control the sound output circuit 142 to emit the sound warning signal, so as to prevent the user from being distracted by the light output circuit 141 outside the vehicle, thereby achieving the function of effective sound and light warning.

[ example of detecting a rear left-side incoming vehicle ]

Further, in an embodiment of the safety detection device 1 of the present embodiment, the safety detection device 1 can be activated along with the start of the vehicle 3, and the design manner of the start of this part is known to those skilled in the art and will not be described herein. When the control circuit 10 starts the detection circuit 12, as shown in fig. 3, the vehicle body 30 driven by the user runs on the road, and at this time, the detection circuit 12 detects that the vehicle 41 approaches the left rear side of the vehicle body 30, and the left side light output circuit 141 of the vehicle body 30 outputs a light warning signal (e.g., flashes) to prompt the user. Meanwhile, the sound output circuit 142 inside the vehicle body 30 will send out a sound warning signal (such as a warning sound), and the user can know that there is a vehicle coming in the left rear lane of the vehicle 3 according to the warning of the light output circuit 141 and the sound output circuit 142. Therefore, it is not appropriate to switch to the left lane while the vehicle 3 is traveling, or it is not appropriate to drive any door locked on the left side of the vehicle body 30 when the vehicle 3 is stopped.

[ example of detecting a rear right-side incoming vehicle ]

Similarly, in an embodiment of the safety detection device 1 of the present embodiment, when the control circuit 10 starts the operation of the detection circuit 12, as shown in fig. 4, the vehicle body 30 driven by the user runs on the road, at this time, the detection circuit 12 detects that the vehicle 42 approaches the right rear side of the vehicle body 30, and the right side light output circuit 141 of the vehicle body 30 outputs a light warning signal (e.g. flashes) to prompt the user. Meanwhile, the sound output circuit 142 inside the vehicle body 30 will send out a sound warning signal (such as a warning sound), and the user can know that there is a vehicle coming in the right rear lane of the vehicle 3 according to the warning of the light output circuit 141 and the sound output circuit 142. Therefore, it is not appropriate to switch to the right lane while the vehicle 3 is traveling, or it is not appropriate to drive any door locked on the right side of the vehicle body 30 when the vehicle 3 is stopped.

It should be noted that, in the embodiments shown in fig. 3 and 4, when the safety detection device 1 detects that a vehicle arrives at a certain side of the rear, the light warning signal output by the vehicle 3 is the same as the coming direction. However, in another embodiment, when the safety detection device 1 detects that the vehicle 3 is coming from a side behind the vehicle, the light warning signal output by the vehicle 3 may be output at the left and right sides of the vehicle 3 at the same time. Furthermore, when the safety detection device 1 detects that a vehicle arrives at a certain side of the rear, the vehicle door can be ensured not to be opened by locking the vehicle door when the vehicle 3 stops, so that traffic accidents are effectively avoided, or when the vehicle is in the process of traveling, a driver can be prompted to pay attention to the coming vehicle at the rear in the lane changing process through sound or light warning, and the function of warning of driving blind spots can be achieved.

[ examples of different vehicle speed detection ]

Referring to fig. 5, the vehicle 3 according to the embodiment of the present invention can also detect the speed of the object moving in the vicinity behind the vehicle 3 through the detection circuit 12 in the safety detection device 1, and further can have different corresponding warning distances for objects with different moving speeds.

For example, when the control circuit 10 activates the detection circuit 12, the vehicle 3 driven by the user is driven in the center lane as shown in fig. 5. The left rear detection circuit 12 of the vehicle 3 at this time detects that the vehicle 43 traveling at the first preset speed is traveling in the left rear lane of the vehicle 3. The detection circuit 12 transmits the detection result to the control circuit 10, and the control circuit 10 controls the light output circuit 141 to output a light-emitting warning signal and controls the sound output circuit 142 inside the vehicle 3 to emit a sound warning signal at a first preset distance from the vehicle 43 to the rear of the vehicle 3, so as to warn the user that the vehicle 43 is about to approach.

The rear right detection circuit 12 of the vehicle 3 detects that the vehicle 44 traveling at the second preset speed runs on the rear right lane of the vehicle 3, the detection circuit 12 transmits the detection result to the control circuit 10, and the control circuit 10 controls the light output circuit 141 to output a light-emitting warning signal and controls the sound output circuit 142 inside the vehicle 3 to emit a sound warning signal at the second preset distance from the vehicle 44 to the rear of the vehicle 3, so as to warn the user that the vehicle 44 is about to approach at the moment. Therefore, the user can know the left and right vehicle coming conditions in time through the mode, and the user can conveniently switch lanes or use the lane as a reference when the vehicle door is opened. The first preset speed is smaller than the second preset speed, and the first preset distance is smaller than the second preset distance.

In short, in an embodiment, when the safety detection device 1 detects that there is a vehicle coming from the rear, it can relatively determine to output the warning signal prompt at different warning distances according to the driving speed of the vehicle coming from the rear. For example, the driving speed of the vehicle 44 shown in fig. 5 is faster than the driving speed of the vehicle 43, so the vehicle 3 performs corresponding control on the warning circuit 14 through the control circuit 10 according to the detection result of the safety detection device 1, thereby the warning distance provided to the vehicle 44 is greater than the warning distance provided to the vehicle 43.

In addition, in one embodiment, when the warning circuit 14 receives the warning signal for warning, the warning signal may also remind the user of the vehicle through different warning manners when the vehicle moves from far to near according to the distance of the vehicle moving behind. For example, the light warning signal can change from constant brightness to flashing, the light warning signal can change from slower flashing frequency to faster flashing frequency, or the sound warning signal can change from small sound to large sound, and so on.

[ Another embodiment of the safety inspection device ]

Referring to fig. 6, the safety detecting device 1a for opening and closing the vehicle door according to the embodiment of the present invention, the safety detecting device 1a shown in this embodiment further includes a release circuit 18, and the release circuit 18 is electrically connected to the control circuit 10, compared to the safety detecting device 1 shown in fig. 1. In one embodiment, the release circuit 18 controls the alarm circuit 14 to stop receiving or resume receiving the alarm signal according to the operation of the user.

For example, the release circuit 18 may obtain the release signal according to the operation of a joystick or a key of the vehicle by the user. In one embodiment, when the detection circuit 12 detects an incoming vehicle at the rear, the control circuit 10 will output a warning signal to the warning circuit 14. At this time, the user can disable the control circuit 10 from outputting the warning signal to the warning circuit 14 by disabling the control circuit 18. The user can then operate the release circuit 18 again, so that the control circuit 10 resumes outputting the warning signal to the warning circuit 14. In the process, when the detection circuit 12 does not detect that a rear vehicle is coming, the control circuit 10 automatically stops outputting the warning signal to the warning circuit 14.

The operation of the control lever refers to the operation of the control lever to a certain position, and the control lever is, for example, a wiper lever, a high beam lever, and a constant speed lever in a vehicle. The operation of the key is pressing of the key, and the key is, for example, a volume adjusting key, a front fog lamp key and the like in a vehicle. However, the present invention is not limited to the above examples.
