Description

Technical Field

[0001] The utility model relates to the technical field of vehicle safety, and particularly relates to a circuit for controlling an automobile window and a vehicle-mounted charger. Background Art

[0002] With the development of the economy and the continuous improvement of people's living standards, automobiles have become a commonly used means of transportation in people's daily lives. However, the number of automobile accidents has also been increasing. A relatively common type of accident is the suffocation incident inside the car. For example, in some cases, due to the negligence of some drivers, it often happens that after some drivers or passengers in the car leave the vehicle, they leave children, pets, or sleeping people in the car. In high-temperature environments such as summer, it is very easy for people or pets to experience changes in the in-vehicle environment characteristics, such as high temperature, lack of oxygen, high carbon dioxide / carbon monoxide concentration, etc., resulting in phenomena such as heat stroke, dehydration, or hypoxia of the people or pets in the car. In severe cases, death may even occur, causing great harm to individuals and families.

[0003] In the prior art, in order to overcome this safety hazard, an alarm function has been added to automobiles. When there are detained people or pets in the car when the vehicle is parked, it will automatically alarm, mainly through a human body infrared detection circuit and an acoustic-optic circuit to activate an acoustic-optic device for reminder; some automobiles have also added communication facilities. After people or pets are detained, a distress message will be sent to the vehicle owner or the outside, relying on the vehicle owner to return and unlock for rescue in the first time, or relying on the people around to discover and rescue by brute force.

[0004] However, during the process of waiting for rescue by others, the waiting time is unpredictable. Once the waiting time for rescue is too long, unpredictable situations may also occur, bringing danger. For example, in the case where the car windows are closed, due to the good sealing effect of the car, the car space is enclosed, and it is difficult for fresh air from the outside to enter the car. The air inside the car does not circulate. When the outside temperature is high and the car is exposed to the sun for 15 minutes, the temperature of the enclosed carriage will rise sharply to 65°C. In such a situation, some accidents are inevitably caused. Summary of the Utility Model

The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0044] Figure 1 It is a schematic structural diagram of a circuit for controlling a car window provided by an embodiment of the present application. As Figure 1 shown, the circuit for controlling a car window provided by this embodiment includes a first monitoring module 110, a second monitoring module 120, and a control module 130.

[0045] In this embodiment, the first monitoring module 110 includes a monitoring end and an output end. The monitoring end of the first monitoring module 110 is used to detect the vital signs in the vehicle and generate a vital sign signal corresponding to the vital signs. The output end of the first monitoring module 110 is used to output the vital sign signal. Among them, the vital sign signal includes at least one of the electromagnetic wave signal reflected by a living body, the breathing signal, and the acoustic signal. Specifically, the electromagnetic wave signal reflected by a living body may be an electromagnetic signal reflected by a human body when a living body is detected to exist or move, and the acoustic signal may be a detected sound signal.

[0046] The second monitoring module 120 includes a monitoring end and an output end. The monitoring end of the second monitoring module 120 is used to detect the environmental characteristics in the vehicle and generate an environmental characteristic signal corresponding to the environmental characteristics. The output end of the second monitoring module 120 is used to output the environmental characteristic signal. Among them, the environmental characteristic signal includes at least one of the temperature signal, the oxygen concentration signal, and the carbon dioxide concentration signal.

[0047] The control module 130 includes a first input end, a second input end, and an output end. The first input end of the control module 130 is connected to the output end of the first monitoring module 110, and the second input end of the control module 130 is connected to the output end of the second monitoring module 120. The control module 130 receives the vital sign signal and the environmental characteristic signal through its first input end and the second input end, and generates a drive control signal according to the vital sign signal and the environmental characteristic signal, and outputs the drive control signal to an external remote control window opening module 140 through the output end.

[0048] The remote control window opening module 140 includes a first button. The control end of the first button is connected to the output end of the control module 130. The first button responds to the drive control signal and generates a remote control signal for controlling all the vehicle windows to open, so as to control all the vehicle windows to open and achieve the purpose of self-rescue.

[0049] It can be understood that the control module 130 determines whether there are living beings with vital signs such as people or pets in the vehicle by obtaining the vital sign signal, and then determines whether the environmental characteristics in the vehicle are conducive to the survival of the people or pets staying in the vehicle at the current time by obtaining the environmental characteristic signal. When the environmental characteristics characterized by the environmental characteristic signal are unfavorable, a drive control signal acting on the first button in the remote control window opening module 140 is generated and output immediately. Further, the first button responds to the drive control signal and generates a remote control signal for controlling all the vehicle windows to open, and controls all the vehicle windows to open, providing sufficient oxygen for the people or pets staying in the vehicle, achieving the first step of self-rescue, so as to avoid the safety hazard of suffocation when the environmental characteristics in the vehicle meet the preset conditions during the waiting for rescue, and improving the safety factor of the vehicle.

[0050] In some embodiments, a wireless transmitter is connected to the output end of the control module 130. Correspondingly, a wireless receiver is connected to the control end of the first button of the external remote control window opening module 140. After the wireless transmitter and the wireless receiver are successfully paired, the control module 130 can send a drive control signal to the wireless receiver connected to the control end of the first button through the wireless transmitter to achieve the opening control of the vehicle window.

[0051] In some embodiments, the output end of the control module 130 can also be connected to a first connection interface. Correspondingly, the control end of the first button of the external remote control window opening module 140 is connected to a second connection interface matching the first connection interface. After the first connection interface and the second connection interface are successfully connected, the control module 130 can send a drive control signal to the second connection interface connected to the control end of the first button through the first connection interface to achieve the opening control of the vehicle window.

[0052] In some embodiments, the first monitoring module 110 and the second monitoring module 120 are mainly used to detect and output a vital sign signal and an environmental characteristic signal after the vehicle is turned off, which can reduce the detection frequency and lower the power consumption of the circuit for controlling the vehicle window.

[0053] In some embodiments, the remote control window opening module 140 is a remote control key of the vehicle or a circuit board of the remote control key. The remote control key is installed at a fixed position of the vehicle and is electrically connected to the control module 130; the first button is the unlock button of the remote control key, and the unlock button controls all the windows of the vehicle to be in the open state in response to a drive control signal with a continuous preset duration.

[0054] It can be understood that generally a vehicle has a spare remote control key, which at least has an unlock button, a lock button, and an open key for the trunk. The remote control key has a circuit board and can realize the opening and closing control of the vehicle door and the trunk. In this embodiment, the remote control window opening module 140 is a remote control key of the vehicle or a circuit board of the remote control key, which is fixed inside the vehicle and is electrically connected to the control module 130 for obtaining the drive control signal output by the control module 130. In this embodiment, the unlock button on the remote control key is used as the first button. After receiving the drive control signal, the first button can control the opening of all the windows of the vehicle. To avoid failure to recognize the drive control signal, in this embodiment, the control module 130 will continuously output a drive control signal with a preset duration. For example, the drive control signal is a signal lasting for 10 s. Only when the first button obtains a continuous drive control signal, will it control the opening of all the windows of the vehicle.

[0055] Figure 2 This is the circuit diagram of the circuit for controlling the vehicle window provided by an embodiment of the present application. As Figure 2As shown, in this embodiment, the control module 130 includes a single-chip microcomputer U1, the first monitoring module 110 includes a human microwave radar sensor U2, and the second monitoring module 120 includes a temperature sensor U3.

[0056] Specifically, the VCC terminal of the human microwave radar sensor U2 is connected to an externally input 5V voltage, and a filtering capacitor C7 is connected. The output terminal of the human microwave radar sensor U2, that is, the OUT terminal, is connected to the 8th pin INTO terminal of the single-chip microcomputer U1 to transmit the detected vital sign signal to the single-chip microcomputer U1. The VDD terminal of the temperature sensor U3 is also connected to an externally input 5V voltage, and a filtering capacitor C6 is connected. The output terminal of the temperature sensor U3, that is, the DQ terminal, is connected to the 37th pin of the single-chip microcomputer U1 to transmit the detected environmental feature signal to the single-chip microcomputer U1. The 33rd pin of the single-chip microcomputer U1 is used to output a drive control signal to the first button.

[0057] It can be understood that the human microwave radar sensor is a non-contact sensor based on microwave radar technology. It can detect human presence, movement, micro-movement, and even breathing signals, and has a wide range of application scenarios and advantages. It specifically uses ultra-wideband and performs high-precision micro-movement detection, and works by emitting high-frequency electromagnetic waves and receiving the reflected echoes. Once a moving object (including a human body) enters the sensing range, it will change the radar signal waveform, and the sensor judges the movement situation within the sensing range based on these changes and triggers corresponding actions. In addition, the microwave radar sensor has high sensitivity and can also detect the micro-movement and breathing signals of the human body to achieve the detection of human static presence. At the same time, the human microwave radar sensor is not affected by environmental factors such as temperature, sound, and dust, and can work stably in various complex environments.

[0058] Compared with the relatively common human body infrared sensors, human body microwave radar sensors show significant advantages in terms of sensing distance, anti-interference ability, sensing sensitivity and accuracy. Based on the Doppler radar principle, the sensing distance of human body microwave radar sensors can reach 8-10 meters, or even farther, with a wider angle and no dead zone. Its radio frequency signal can penetrate non-metallic objects such as plywood, thin wood boards, plastics and opaque glass, which is convenient for users to choose unique installation positions; while the sensing distance of human body infrared sensors is greatly affected by seasons. In winter, the sensing distance may be only 3-5 meters, and in summer, it is shortened to 1-3 meters. Moreover, it is easily affected by obstacles, resulting in unstable sensing effects. At the same time, human body microwave radar sensors have stronger anti-interference ability and are not affected by environmental factors such as heat sources, light sources, airflows, dust, smoke, temperature, noise, humidity, and dust, with stable and reliable performance; while human body infrared sensors are easily interfered by heat sources and light sources. When the ambient temperature is close to the human body temperature, the sensitivity significantly decreases or even fails. Most importantly, human body microwave radar sensors have high sensitivity and accuracy, can detect the micro-movement and breathing signals of the human body, and realize the detection of the static presence of the human body. The built-in algorithms and signal processing technologies can further improve the accuracy and stability of detection; while human body infrared sensors, although sensitive to thermal radiation, may cause false alarms or missed alarms due to environmental interference or obstacles in some cases.

[0059] In some embodiments, the first monitoring module 110 further includes at least one of a sound detector and a camera installed in the vehicle.

[0060] It can be understood that the sound detector, also known as the sound sensor or audio sensor, can be used to continuously monitor whether there is sound in the vehicle, and the camera can be used to continuously record the situation in the vehicle. In this embodiment, the sound detector and the camera are used as auxiliary monitors of the human body microwave radar sensor so that the control module 130 can obtain more accurate monitoring signals. In necessary cases, sounds, photos or videos can also be transmitted to the vehicle owner to timely discover potential safety hazards.

[0061] In some embodiments, the second monitoring module 120 further includes at least one of an oxygen sensor and a carbon dioxide sensor.

[0062] It is understandable that after the vehicle is turned off, especially when the vehicle compartment is airtight, due to the good sealing effect of the vehicle, the vehicle space is enclosed, and it is very difficult for fresh air from the outside to enter the vehicle. The air inside the vehicle does not circulate. In this case, the temperature inside the vehicle will definitely rise. Especially in the case of being exposed to the sun in summer, the temperature inside the vehicle will rise sharply. Therefore, after the vehicle is turned off, the first environmental characteristic to change inside the vehicle must be the temperature. The temperature sensor can monitor the change of the temperature inside the vehicle in the first time. On the premise that the first monitoring module 110 monitors the presence of life characteristics inside the vehicle, combined with the monitoring of the temperature change inside the vehicle, it is possible to more accurately judge that there are detained persons or pets inside the vehicle. At this time, no matter which rescue method is used, first of all, it is necessary to ensure that the detained persons or pets are no longer in an airtight environment.

[0063] Similarly, for an airtight space with vital signs, since both people and pets need to breathe, after a certain period of time, the oxygen concentration inside the vehicle decreases and the carbon dioxide concentration increases. Monitoring the oxygen concentration and / or carbon dioxide inside the vehicle while monitoring the temperature inside the vehicle also helps the control module 130 accurately judge whether there are detained persons or pets inside the vehicle.

[0064] Figure 3 The structural schematic diagram of the circuit for controlling the vehicle window provided by another embodiment of the present application. As Figure 3 shown, the circuit for controlling the vehicle window provided by this embodiment, on the basis of any of the above embodiments, further includes a window driving module 150 connected between the control module 130 and the remote control switch module.

[0065] In this embodiment, the input end of the window driving module 150 is connected to the first output end of the control module 130 for obtaining a driving control signal. The output end of the window driving module 150 is connected to the input end of the remote control window opening module 140. After receiving the driving control signal output by the control module 130, the window driving module 150 responds to the driving control signal, generates a power output and acts on the first button, and controls all the windows of the vehicle to be in the open state by pressing the first button, simulating the physical button of the remote control switch, and realizing automatic window opening.

[0066] In some embodiments, the window driving module 150 may be a driving motor. After receiving the driving control signal, it outputs a pressing force through its output end and lasts for a certain period of time, acting on the first button, that is, it can act on the unlocking button of the remote control key to realize automatic window opening.

[0067] In summary, the circuit for controlling the car window provided by the embodiment of the present application detects the life characteristics and environmental characteristics inside the vehicle through the first monitoring module and the second monitoring module respectively, and generates corresponding life characteristic signals and environmental characteristic signals. The control module generates a drive control signal acting on the first button in the remote control window opening module according to the life characteristic signals and environmental characteristic signals. Further, the first button responds to the drive control signal to generate a remote control signal for controlling all the car windows to open, so as to achieve the purpose of preventing asphyxiation.

[0068] When a person or a pet is trapped in a closed vehicle in the embodiment of the present application, all the windows can be automatically opened through the remote control window opening module, effectively avoiding the safety hazard of asphyxiation caused by the change of the environmental characteristics inside the vehicle during the waiting for rescue, greatly improving the safety factor of the vehicle. Moreover, this circuit has made a simple improvement on the existing structure, with a simple structure and low cost, and has wide practical value, being suitable for popularization and application.

As Figure 4 shown, on the basis of any of the above embodiments, the circuit for controlling the car window provided by this embodiment further includes a power supply module 160 for supplying power to the control module 130.

[0070] In practice, during the normal use of the vehicle, its control system can obtain a power supply signal from the vehicle battery to realize the control of the vehicle. However, after the vehicle is turned off, under the condition that the doors and windows are locked, the control module 130 of the circuit for controlling the car window in the embodiment of the present application can be powered by the power supply module 160 to control the vehicle to automatically open the window without connecting to the vehicle battery and consuming the power of the battery; at the same time, it can also avoid the situation that the entire circuit for controlling the car window stops running due to the discharge of the vehicle battery.

As Figure 5 shown, in this embodiment, the power supply module 160 includes a power input component 501, a charging component 502, a battery component 503, and a voltage conversion component 504 connected in sequence. Among them, the power input component 501 is connected to the cigarette lighter plug of the vehicle to obtain the externally input voltage, charge the battery component 503 through the charging component 502, and convert it into the voltage required by the control module 130 through the voltage conversion component 504.
