The door lock mentioned here refers to, for example, a door lock of a vehicle.

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.

The warning circuit 14 can be, for example, one or a combination of a light output circuit 141 that emits a light warning signal or a sound output circuit 142 that can emit a sound warning signal. The light output circuit 141 is, for example, a rearview mirror LED direction light circuit of a vehicle. The sound output circuit 142 is, for example, one or any combination of sound devices such as buzzers, buzzers, or speakers. However, this creation does not limit the way in which the detection circuit 12 and the warning circuit 14 are arranged.

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 chip (SOC). However, this creation is not limited to the examples given above.

In an embodiment, when the control circuit 10 knows that a vehicle or an object is approaching the rear of the vehicle through the detection circuit 12, the control circuit 10 outputs a locking signal to the door lock 16 at this time, so that the door lock 16 can be locked according to this The signal locks the door of the vehicle. The lock signal is, for example, a door central 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 issue a light warning signal or a sound warning signal accordingly. When the control circuit 10 does not know that a vehicle or an object is approaching the rear of the vehicle through the detection circuit 12, the control circuit 10 does not output a lock signal and a warning signal.

Please refer to FIG. 2. FIG. 2 is a schematic diagram of the safety detection device provided in the vehicle in this creative embodiment. When the safety detection device 1 described in this embodiment is applied to a vehicle 3, the control circuit 10 and the detection circuit 12 therein are respectively disposed at appropriate positions of the vehicle body 30 according to their functional designs.

[Example of detecting a car coming to the left from the rear]

Further, in one implementation aspect of the safety detection device 1 of this embodiment, the safety detection device 1 can be activated as the vehicle 3 is started. The design method for the start of this part belongs to those skilled in the art. I will not repeat them here. When the control circuit 10 starts the detection circuit 12 to operate, as shown in FIG. 3, the vehicle body 30 driven by the user travels on the road. At this time, the detection circuit 12 detects that a vehicle 41 is approaching to the left rear of the vehicle body 30 The left light output circuit 141 of the vehicle body 30 will output a light warning signal (such as flashing) to alert the user. At the same time, the sound output circuit 142 inside the vehicle body 30 will emit a sound warning signal (such as a warning sound), and the user knows that there is an incoming car on 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, if the vehicle 3 is running at this time, it is not suitable to switch to the left lane, or when the vehicle 3 is stopped at this time, it is not suitable to open any door on the left side of the vehicle body 30 that is locked.

[Example of detecting a car coming to the right from the rear]

Similarly, in one embodiment of the safety detection device 1 of this embodiment, when the control circuit 10 activates the detection circuit 12, the vehicle body 30 driven by the user runs on the road as shown in FIG. 4, At this time, the detection circuit 12 detects that a vehicle 42 is approaching on the right rear of the vehicle body 30, and the right light output circuit 141 of the vehicle body 30 outputs a light warning signal (such as flashing) to alert the user. At the same time, the sound output circuit 142 inside the vehicle body 30 will emit a sound warning signal (such as a warning sound), and the user knows that there is an incoming car 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, if the vehicle 3 is running at this time, it is not suitable to switch to the right lane, or when the vehicle 3 is stopped at this time, it is not suitable to open any door on the right side of the vehicle body 30 that is locked.

It is worth noting that in the embodiments shown in FIG. 3 and FIG. 4 above, when the safety detection device 1 detects a vehicle coming from the rear to a certain side, the light warning signal output by the vehicle 3 at this time is the same as the existing one. Warning on the same side of the car. However, in another embodiment, when the safety detection device 1 detects a vehicle coming from a certain side behind the vehicle 3, the light warning signals output by the vehicle 3 may also be output on the left and right sides of the vehicle 3 at the same time. Furthermore, when the safety detection device 1 detects that a vehicle is coming from the rear to a certain side, when the vehicle 3 stops, the door can be locked to ensure that the door is not opened, effectively avoiding traffic accidents, or when the vehicle is traveling The sound or light warning can be used to remind the driver to notice that there is a car coming behind during the lane change, and the function of the blind spot warning can be reached.

[Examples of different speed detection]

Please refer to FIG. 5. The vehicle 3 in this creative embodiment can also detect the speed of the moving object near the vehicle 3 through the detection circuit 12 in the safety detection device 1, and can further target objects with different moving speeds. Corresponding to different warning distances.

For example, when the control circuit 10 starts the detection circuit 12 to operate, as shown in FIG. 5, the vehicle 3 driven by the user travels in the central lane. At this time, the left rear detection circuit 12 of the vehicle 3 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. The control circuit 10 can control the light output circuit 141 to output a light-emitting warning signal at a first preset distance from the vehicle 43 to the rear of the vehicle 3, while controlling the sound output inside the vehicle 3 The circuit 142 emits an audible warning signal to warn the user that the vehicle 43 is approaching.

The right rear detection circuit 12 of the vehicle 30 detects that the vehicle 44 traveling at the second preset speed is traveling in the right rear lane of the vehicle 3, the detection circuit 12 transmits the detection result to the control circuit 10, and the control circuit 10 may At a second preset distance from the vehicle 44 to the rear of the vehicle 3, the light output circuit 141 is controlled to output a luminous warning signal, and the sound output circuit 142 inside the vehicle 3 is controlled to emit a sound warning signal to warn the user that the vehicle 44 is about to near. According to this, the above method can let the user know the situation of the left and right vehicles in time, which is convenient for the user to switch the lane or open the door as a reference. The first preset speed is less than the second preset speed, and the first preset distance is less than the second preset distance.

To put it simply, in an embodiment, when the safety detection device 1 detects that there is an incoming vehicle behind, it can relatively decide to output a warning signal prompt at different warning distances according to the driving speed of the incoming vehicle. 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, so that the vehicle 44 The warning distance provided is greater than the warning distance to the vehicle 43.

In addition, in one embodiment, when the warning circuit 14 receives a warning signal to warn, the warning signal can also remind the user to pay attention through different warning methods when the moving vehicle in the rear approaches from near to far. For example, the light warning signal can be changed from constant bright to blinking, the light warning signal can be changed from a slower blinking frequency to a faster blinking frequency, or the sound warning signal is changed from whisper to louder, and so on.

[Another embodiment of a security detection device]

Referring to FIG. 6, the safety detection device 1a for opening and closing the door of the present embodiment. Compared with the safety detection device 1 of FIG. 1, the safety detection device 1a shown in this embodiment further includes a release circuit 18 Sexual connection control circuit 10. In one embodiment, the release circuit 18 controls the warning circuit 14 to stop receiving or resume receiving the warning signal according to the user's operation.

For example, the release circuit 18 may obtain a release signal according to a user operating a joystick or keys of the vehicle. In one embodiment, when the detection circuit 12 detects that a vehicle is coming from behind, the control circuit 10 will output a warning signal to the warning circuit 14. At this time, the user can make the control circuit 10 stop outputting the warning signal to the warning circuit 14 by releasing the operation of the circuit 18. After that, the user can also operate the release circuit 18 again, so that the control circuit 10 resumes outputting the warning signal to the warning circuit 14. During the process, when the detection circuit 12 does not detect that a vehicle is coming from behind, the control circuit 10 will automatically stop outputting the warning signal to the warning circuit 14.

The manipulation of the joystick refers to turning the joystick to a certain position. The joystick is, for example, a wiper lever, a high beam head lever, or a constant speed lever in a vehicle. The operation of the above-mentioned keys refers to pressing of the keys, such as volume adjustment keys and front fog light keys in the vehicle. However, this creation is not limited to the examples given above.
