DETAILED DESCRIPTION

[0020] The utility model is further described below based on the accompanying drawings and some embodiments.

[0021] Figure 1-5In the invention, a device for avoiding a baby trapped in a car comprises a baby detection component capable of detecting that a baby is trapped alone in a car, an environment detection component capable of detecting the living environment of the baby in the car, and a risk avoidance component capable of automatically opening a door 1 in an emergency. The baby detection component, the environment detection component, and the risk avoidance component are all arranged in a car and are all connected to a central control system of the car. The central control system of the car is the same as the central control system of a car in the prior art, such as the car system used by BYD, Buick, etc., which has a processor inside and can process information collected by sensors at various locations on the car.

[0022] The risk avoidance component includes an unlocking component for unlocking the door 1 by pushing open the door handle 5, and a pushing component for pushing open the door 1 after the door handle 5 is pushed open. The unlocking component is arranged in the door 1 of the car, and the unlocking end is connected to the door handle 5. The pushing component is arranged at the bottom of the car, and the pushing end contacts the bottom of the door 1 when it is pushed open.

[0023] The unlocking assembly includes an opening rod 2, a slide rail 3, and a linear motor 4 that can drive the opening rod 2 to move and open the door handle 5. The slide rail 3 is concealed in the car door 1, and the linear motor 4 is arranged on the slide rail 3. One end of the opening rod 2 is connected to the bottom of the door handle 5 through a first hinge 6, close to the rotation unlocking end of the door handle 5, and the other end is connected to the linear motor 4 through a second hinge; the opening rod 2 includes a first rod body 7, a second rod body 8, and a spring 9 that can extend the length of the rod body in the normal door opening state. The first rod body 7 and the second rod body 8 are hollow structures. One end of the spring 9 is connected to the bottom of the first rod body 7, and the other end is connected to the bottom of the second rod body 8. The linear motor 4 is connected to the output end of the car central control; the above-mentioned second hinge has the same structure as the first hinge 6; the above-mentioned car door lock has the same structure as the car door lock in the prior art, such as the mechanical door handles of Buick Verano, Excelle and other models.

[0024] In this embodiment, the pushing assembly includes an electric telescopic rod 10, which is arranged at the bottom of the vehicle body, and the telescopic end contacts the bottom of the door 1 when pushing the door 1 open, and the electric telescopic rod 10 is connected to the output end of the car's central control; the above-mentioned electric telescopic rod 10 is a linear or spiral electric telescopic rod 10 structure commonly seen in the prior art.

[0025] In this embodiment, the baby detection component includes a plurality of pressure sensors 12 and a camera 13 for collecting information about people in the car. The pressure sensor 12 is arranged in the seat, and the camera 13 is arranged on the rearview mirror inside the car. A pressure sensor 12 may be provided under each car seat, so that more accurate data may be collected. The rear seats may be arranged according to actual conditions. The pressure sensor 12 and the camera 13 are both connected to the input end of the car's central control. The pressure sensor 12 and the camera 13 respectively collect information about people inside the car and transmit it to the car's central control. The pressure sensor adopts a film-type seat pressure sensor. The pressure sensor is made of environmentally friendly PET soft material and is ultra-thin in design; the camera is a common camera in the prior art, such as the existing camera installed in the car of BYD car frigate and other models; the above-mentioned pressure sensor and camera respectively collect pressure information and image information on the seat, which can be transmitted to the car's central control for processing, and then transmitted to the linear motor, electric telescopic rod, and speaker. This signal transmission method can refer to the transmission method of automatic braking of the car. For example, in existing Xiaomi, Huawei and other brand cars, the radar transmits the surrounding obstacle information to the central control. When an obstacle appears in front, the central control enables the car to brake automatically.

[0026] In this embodiment, the environmental detection component includes a gas concentration sensor 13 and a temperature and humidity sensor 14. The gas concentration sensor 13 and the temperature and humidity sensor 14 are both arranged in the vehicle body. The gas concentration sensor 13 and the temperature and humidity sensor 14 are both connected to the input end of the car's central control. The gas concentration sensor 13 and the temperature and humidity sensor 14 collect the gas concentration information and temperature and humidity information in the car and transmit them to the car's central control.

[0027] In this embodiment, a loudspeaker 15 is also included, which is arranged outside the vehicle body and is used to call for help from passers-by.

[0028] During the specific implementation of this embodiment, when there is only an infant in the car, the pressure sensor 12 can transmit the infant's pressure information to prove that the infant is in the car, and the camera 13 can collect the infant's facial and limb movements. After the above information is transmitted to the car central control, when there is insufficient oxygen concentration, high temperature and humidity, abnormal limb movements or facial expressions of the infant in the car, the car central control will first automatically unlock the door 1, and then transmit the information to the linear motor 4 and the speaker 15. The speaker 15 plays a voice for help to ask for help from passers-by. The linear motor 4 moves the two ends of the push-open rod 2 to rotate around the first hinge 6 and the second hinge, thereby pushing open the door handle 5. After pushing open, the information is transmitted to the electric telescopic rod 10, so that the electric telescopic rod 10 is extended to push open the door 1, so that the trapped infant and young child can be relieved in time due to insufficient oxygen concentration, high temperature and humidity in the car, and can get help from passers-by in time.
