[0021] In addition, it should be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method, and the execution order of the multiple steps can be interchanged with each other without departing from the scope of the claims, and some steps can also be deleted.
[0022] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a radar device 100 provided in an embodiment of the present application. As shown in Figure 1 , the radar device 100 can be arranged on the top of the car.
[0023] Please refer to Figure 2 , Figure 2 is a module schematic diagram of a radar device 100 provided in an embodiment of the present application. As shown in Figure 2 , the radar device 100 can include a radar guide rail 10, a detection radar 20, and a driving device 30. The radar guide rail 10 is installed on the inner top of the car, the detection radar 20 is slidably installed on the radar guide rail 10, and the detection radar 20 is used to detect living body features. The driving device 30 is connected to the detection radar 20 to drive the detection radar 20 to move along the radar guide rail 10.
[0024] Therefore, by moving the detection radar 20 along the radar guide rail 10, the detection area of the detection radar 20 can be changed, the detection area of the detection radar 20 can be increased, the number of detection radars 20 required for the car to perform living body detection can be reduced, and the cost of performing living body detection on the vehicle can be reduced.
[0025] It can be understood that when the car is in the lower electric lock car working condition, the driving device 30 drives the detection radar 20 to move along the radar guide rail 10, and the detection radar 20 moves to a certain position to emit a detection wave, and the living body detection of the car is realized according to the detection wave reflected back to the detection radar 20.
[0026] As shown in Figure 3 The radar guide rail 10 can include a first guide rail 11 and a second guide rail 12 arranged in parallel, and two ends of the detection radar 20 are slidably installed in the first guide rail 11 and the second guide rail 12, respectively. In this way, the detection radar 20 can stably move along the first guide rail 11 and the second guide rail 12.
[0027] Further, the first guide rail 11 and the second guide rail 12 extend from the rear seat area of the vehicle to the front seat area, so that the driving device 30 can drive the detection radar 20 to move between the rear seat area and the front seat area. That is, the axial direction of the first guide rail 11 and the second guide rail 12 extends from the rear seat to the front seat of the vehicle.
[0028] Based on this, the detection radar 20 can completely detect the rear seat area and the front seat area of the vehicle, realizing that the entire vehicle interior space of the vehicle is detected by a single detection radar 20, and further reducing the cost of living body detection of the vehicle.
[0029] Specifically, sliding grooves 13 are formed in the first guide rail 11 and the second guide rail 12, and sliding blocks (not shown in the figure) are protruded on the bottom of the detection radar 20 corresponding to the sliding grooves 13 in the first guide rail 11 and the second guide rail 12. The sliding blocks are clamped in the sliding grooves 13 and can slide along the sliding grooves 13. In this way, when the driving motor drives the telescopic rod to extend or retract through the transmission mechanism, the telescopic rod drives the detection radar 20 to move, and the sliding blocks of the detection radar 20 slide along the sliding grooves 13 of the first guide rail 11 and the second guide rail 12.
[0030] Of course, in the embodiment of the present application, the radar guide rail 10 can also be provided with only a single guide rail, and the detection radar 20 can be slidably installed in the guide rail. For example, the guide rail is provided with a sliding groove 13, and a sliding block is protruded on the bottom of the detection radar 20 corresponding to the sliding groove 13. The sliding block is clamped in the sliding groove 13 and can slide along the sliding groove 13. In this way, the structure of the radar guide rail 10 can be simplified, and the cost can be reduced.
[0031] As shown in Figure 4 The radar device 100 can also include a control device 40 connected with the driving device 30, and the control device 40 is used to control the driving device 30 to drive the detection radar 20 to slide along the radar guide rail 10.
[0032] Further, the control device 40 is also used to control the driving device 30 to drive the detection radar 20 to slide to different positions of the radar guide rail 10 after the vehicle is turned off by the power lock, and control the detection radar 20 to perform living body detection on the corresponding area at each position.
[0033] The control device 40 controls the drive device 30 to drive the detection radar 20 to move to any position and stay there for a preset time. The detection radar 20 performs liveness detection within the preset time. The preset time can be set according to actual needs, such as 5 seconds, 10 seconds, 12 seconds, etc.
[0034] In some embodiments, such as Figure 3 As shown, the default position of the detection radar 20 is Figure 2 At position A, when the car is unlocked, the detection radar 20 directly performs liveness detection at position A and outputs a detection signal based on the liveness detection result. The detection area of the detection radar 20 at position A can be as follows: Figure 1 As shown. If no living body is detected at position A, the control device 40 controls the drive device 30 to drive the detection radar 20 to move to... Figure 2 The detection radar 20 is positioned at location B, and is controlled to remain at location B for a preset time. Upon reaching location B, the detection radar 20 performs a liveness detection and outputs a detection signal based on the result. If no liveness is detected at location B, the control device 40 controls the drive device 30 to move the detection radar 20 to... Figure 2 The detection radar 20 is positioned at position C, and stays at position C for a preset time. After reaching position C, the detection radar 20 performs liveness detection and outputs a detection signal based on the liveness detection result. It can be understood that as the detection radar 20 moves from position A to position C, its detection area also moves from the front row area of the car to the rear row area, thereby achieving liveness detection within the car's interior space.
[0035] In this embodiment, when the detection radar 20 detects a living being at any location, it can output a detection signal indicating the presence of a living being inside the vehicle and send the detection signal to the control device 40 or other controllers of the vehicle. The control device 40 or other controllers output an alarm signal based on the detection signal. This alarm signal can control the vehicle to sound its horn, or it can control the vehicle to flash its hazard lights and sound its horn, to remind people outside the vehicle or the vehicle owner that there is a living being inside the vehicle and to be aware of safety. Other controllers of the vehicle can be, for example, a vehicle threshold controller, a vehicle controller, etc.
[0036] Furthermore, if the detection radar 20 detects a living person inside the vehicle at position A, the vehicle will sound an alarm. The detection radar 20 can send a detection signal to the control device 40, which can then stop the drive device 30 from moving the detection radar 20. If the detection radar 20 detects a living person inside the vehicle at position B, the vehicle will sound an alarm. The detection radar 20 can send a detection signal to the control device 40, which can then stop the drive device 30 from moving the detection radar 20 to position C and instead control the drive device 30 to return the detection radar 20 to position A. Of course, if the detection radar 20 detects a living person at position B or C, the control device 40 may choose not to control the drive device 30 to return the detection radar 20 to position A, and instead move the detection radar 20 to position again for the next live person detection.
[0037] In some embodiments, such as Figure 5 As shown, the drive device 30 may include a drive motor 31, a transmission mechanism 32, and a telescopic rod 33. The drive motor 31 is connected to the transmission mechanism 32, the transmission mechanism 32 is connected to the telescopic rod 33, and the telescopic rod 33 is connected to the detection radar 20. The transmission mechanism 32 is used to transmit the driving force output by the drive motor 31 to the telescopic rod 33, driving the telescopic rod 33 to reciprocate, thereby driving the detection radar 20 to move on the detection guide rail.
[0038] It is understood that the drive motor 31 is connected to the control device 40, and the control device 40 controls the drive motor 31 to run, thereby controlling the telescopic rod 33 to extend and retract, so as to move the detection radar 20.
[0039] The drive motor 31 can be located at the end of the radar guide rail 10.
[0040] Specifically, the drive motor 31 can be located at the middle of the ends of the first guide rail 11 and the second guide rail 12.
[0041] In some embodiments, the detection radar 20 can be configured as a millimeter-wave radar. Millimeter-wave radar is capable of accurately detecting the rise and fall of chest breathing within its detection area, and can detect the presence of a living body within its detection area with great precision.
[0042] Furthermore, millimeter-wave radar can also determine the characteristics of people forgotten in a vehicle based on detected chest breathing features, such as whether the forgotten person is an elderly person or a child.
[0043] The application further provides an automobile comprising the radar device 100, which can comprise the radar guide rail 10, the detection radar 20 and the driving device 30. The radar guide rail 10 is installed on the inner top of the automobile, the detection radar 20 is slidably installed on the radar guide rail 10, and the detection radar 20 is used for detecting living body features. The driving device 30 is connected to the detection radar 20 to drive the detection radar 20 to move along the radar guide rail 10.
[0044] The specific structure and effects of the automobile of the application are described above in the radar device 100, and will not be repeated here.
[0045] The above embodiments are only preferred embodiments of the application and do not limit the scope of the application.
