[0019] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0021] Figure 1 This is a schematic diagram of a child protection system left in a vehicle according to an embodiment of the present invention.

[0022] Reference numerals: Child protection system left in the vehicle 1, electromagnetic adsorption locking device 11, first buckle 12, second buckle 13, locked part 14, return spring 15, power supply device 20, volume detection device 30, trigger 41, first fuse 51, second fuse 52, first battery 60, vital sign detection device 70, body processor 81, door electric function processor 82, fuse function processor 83, body battery 90, door 2, body 3. Detailed Implementation

[0023] This application is based on the inventor's discoveries and understanding of the following facts and problems:

[0024] In-vehicle child protection systems, which are related technologies, can actively unlock the car doors through the vehicle's electronic unlocking system when a child is detected crying inside the car. However, the electronic unlocking system is prone to failure due to special circumstances, which can cause the car doors to fail to unlock properly, increasing the difficulty of rescue.

[0025] Some vehicles have both electronic and mechanical door locking devices. When the child safety system left in the vehicle attempts to unlock the door, only one locking device may be unlocked, leaving the door unable to be opened.

[0026] In-vehicle child protection systems in related technologies collect and identify sounds using microphones and other sound receiving devices installed inside the vehicle. They identify whether the sound is a child crying and whether the crying is urgent. However, because sound primarily travels through the air between the child and the sound receiving device, and the vehicle environment is relatively enclosed, the air quality inside can easily change over time. For example, as the time a child is left in the car increases, oxygen levels decrease and carbon dioxide levels increase; or the temperature inside the car rises under sunlight. These changes in the air environment cause variations in the sound collected by the sound receiving device, leading to errors in the identification and judgment of the child's cries and affecting the sound recognition accuracy.

[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] The following description, with reference to the accompanying drawings, describes a child protection system 1 for leaving children in a vehicle according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the in-vehicle child protection system 1 according to an embodiment of the present invention includes a door locking device, a power supply device 20, a crying recognition device, a volume detection device 30, a mechanical triggering device, and a fuse device.

[0032] The door locking device is used to lock the door 2. The power supply device 20 is electrically connected to the door locking device. The crying sound recognition device is adapted to recognize crying sounds inside the vehicle. The volume detection device 30 is adapted to detect the volume of the crying sounds. The mechanical triggering device is electrically connected to the volume detection device 30 and has a trigger element 41 that moves with the volume level. The trigger element 41 has at least one fused position, and when the volume reaches a predetermined volume, the trigger element 41 moves to the fused position. The fused device is connected between the door locking device and the power supply device 20 and disconnects the electrical connection between the door locking device and the power supply device 20 when the trigger element 41 is in the fused position.

[0033] Specifically, the door locking device locks the door 2 when powered by the power supply device 20, and unlocks the door 2 after power is lost. The power supply device 20 can be electrically connected to the door electric function processor 82 to control the locking and unlocking of the door 2 under normal conditions.

[0034] It is important to understand here that the "movement" of trigger 41 can include rotation and sliding. Figure 1 An embodiment in which the trigger 41 is rotatably disposed is shown.

[0035] The "predetermined volume" can be obtained through big data, machine learning, and other methods, with 95-105 decibels being the preferred value.

[0036] The following is for reference. Figure 1 The working process of the in-vehicle child protection system 1 according to an embodiment of the present invention is described.

[0037] When a child is locked inside a vehicle, if the child feels uncomfortable or cries due to external stimuli, the crying sound recognition device detects the crying sound inside the vehicle, the volume detection device 30 detects the volume of the crying sound, and the trigger 41 of the mechanical trigger device moves according to the volume level until the volume reaches the predetermined volume. At this point, the trigger 41 reaches the fuse position, causing the fuse to melt and disconnect the power supply device 20 from the door locking device. This causes the door locking device to lose power, thereby unlocking the door 2 and allowing rescuers outside the vehicle to open the door 2 to rescue the child left inside.

[0038] According to an embodiment of the present invention, the in-vehicle child protection system 1, by setting a fuse device and a mechanical triggering device, achieves mechanical triggering of the fuse device by moving the trigger 41. When the child's crying is greater than a predetermined volume, the power supply to the door locking device is cut off, thereby unlocking the door 2 and allowing the door to be opened. Since the fuse device is independent of the vehicle's original door electric function processor 82 and the mechanical triggering device uses mechanical triggering of the fuse device, compared with the method of unlocking the door using an electronic control system in related technologies, it is easier to ensure the reliable triggering of the fuse device, avoid the problem of the door not being able to open when the door's electronic control function fails, ensure that the door can be opened when a child is left in the vehicle, prevent the child from being left in the vehicle for a long time and causing an accident, and improve the reliability of child protection.

[0039] Therefore, the in-vehicle child protection system 1 according to the embodiments of the present invention has advantages such as high reliability.

[0040] The following description, with reference to the accompanying drawings, describes a child protection system 1 for leaving children in a vehicle according to a specific embodiment of the present invention.

[0041] In some specific embodiments of the present invention, such as Figure 1 As shown, the in-vehicle child protection system 1 according to an embodiment of the present invention includes a door locking device, a power supply device 20, a crying recognition device, a volume detection device 30, a mechanical triggering device, and a fuse device.

[0042] Advantageously, the in-vehicle child protection system 1 also includes an in-vehicle environment stabilization device, which includes at least one of an air composition stabilization device and a temperature stabilization device. The in-vehicle environment stabilization device is electrically connected to the cry recognition device and operates when the cry recognition device detects the cry. The air composition stabilization device is adapted to maintain changes in the oxygen and carbon dioxide content inside the vehicle less than or equal to a predetermined content threshold, and the temperature stabilization device is adapted to maintain changes in the temperature inside the vehicle less than or equal to a predetermined temperature threshold. Specifically, the air composition stabilization device may include an oxygen generator, etc. Those skilled in the art will understand that the predetermined content threshold and the predetermined temperature threshold can be derived through big data, machine learning, etc. This ensures the stability of the air environment inside the vehicle. Since the cry from the child as the sound source is mainly transmitted through the air to the cry recognition device, maintaining a stable air environment inside the vehicle ensures stable sound transmission, preventing changes in the air environment from affecting the cry recognition device's reception and recognition of the cry, ensuring accurate and reliable cry recognition, and ensuring that the car door can be opened promptly when needed while avoiding accidental opening due to recognition errors.

[0043] Specifically, such as Figure 1 As shown, the in-vehicle child protection system 1 also includes a first battery 60, and when the trigger 41 is in the fuse position, it connects the first battery 60 and the fuse device. Specifically, as Figure 1 As shown, the trigger 41 can be a pointer and is rotatably configured. This not only allows for the use of an independent battery to power the fuse, but also makes the triggering of the fuse more reliable by connecting the first battery 60 and the fuse through the trigger 41.

[0044] Furthermore, such as Figure 1 As shown, the power supply device 20 is a second storage battery. This allows for the use of an independent storage battery to power the door locking device, avoiding the need for a unified power supply from the vehicle body battery. This also prevents the door locking device from losing power and failing to operate normally due to factors such as failure of the vehicle body battery or power supply lines.

[0045] Specifically, the power supply unit 20 is electrically connected to the door electric function processor 82. This allows the door electric function processor 82 to control the normal locking and unlocking of the door 2.

[0046] More specifically, such as Figure 1As shown, the door locking device includes an electromagnetic adsorption locking device 11 and a latch locking device. The fusible device includes a first fusible device 51 and a second fusible device 52. The electromagnetic adsorption locking device 11 is electrically connected to the power supply device 20 through the first fusible device 51 and is disconnected when the trigger 41 is in the fusible position. The latch locking device includes a locking member, a locked member 14, and a return spring 15. The locking member can switch between a locked position that locks the locked member 14 and an unlocked position that releases the locked member 14. The return spring 15 normally drives the locking member to move towards the unlocked position. The second fusible device 52 is adapted to hold the locking member in the locked position and release the locking member when the trigger 41 is in the fusible position. Specifically, the locking member includes a first latch 12 and a second latch 13. The return spring 15 is connected to at least one of the first latch 12 and the second latch 13. The locked member 14 is located on the vehicle body 3, and the locking member is located on the door 2. This allows the first fuse 51 and the second fuse 52 to simultaneously fuse the electromagnetic adsorption locking device 11 and the latch locking device, respectively, achieving simultaneous unlocking of the electronic locking and mechanical locking, ensuring that the car door can be opened, and further improving the reliability of the child protection system 1 left in the car.

[0047] Optionally, the crying sound recognition device is adapted to identify the crying sound by frequency and decibels to distinguish between everyday crying and cries for help. When the crying sound recognition device detects an everyday crying sound, it prevents the volume detection device from operating; when it detects a cry for help, it allows the volume detection device to operate. Those skilled in the art will understand that "identifying the crying sound by frequency and decibels to distinguish between everyday crying and cries for help" can be achieved by determining specific values ​​through big data, machine learning, or by pre-recording everyday crying sounds and comparing the detected crying sound with the pre-recorded everyday crying sounds. This allows the volume detection device and the fuse to be triggered only when a child cries for help, preventing everyday crying sounds from activating the fuse and causing the car door to unlock unexpectedly.

[0048] More advantageously, such as Figure 1 As shown, the in-vehicle child protection system 1 also includes a life detection device 70. The life detection device 70 is adapted to detect whether there is a living being inside the vehicle. When the life detection device 70 detects no living being inside the vehicle, it prevents the volume detection device from operating; when the life detection device detects a living being inside the vehicle, it allows the volume detection device to operate. Specifically, the life detection device 70 can be a millimeter-wave radar. This allows the detection of a living being inside the vehicle to determine whether the crying sound originates from inside or outside the vehicle, preventing crying sounds from outside the vehicle from activating the fuse and causing the door to open unexpectedly.

[0049] In some embodiments, the in-vehicle child protection system 1 further includes a soothing device, which includes at least one of an audio playback device and a negative ion generator. The soothing device is electrically connected to the cry detection device to activate when the cry detection device detects crying sounds inside the vehicle. Specifically, the soothing device can play music when it is running. This allows for the playback of soothing audio or an increase in negative ion concentration upon detecting crying sounds, thereby improving the comfort of a child left in the vehicle and preventing the child from becoming overly agitated due to being trapped.

[0050] In some embodiments, the in-vehicle child protection system 1 further includes a secondary locking device and an identification device. The secondary locking device is adapted to lock or unlock the vehicle door, and the identification device is electrically connected to the secondary locking device. The identification device is adapted to authenticate the identity of rescue personnel outside the vehicle and compare it with stored identity information. When the identity information of the rescue personnel outside the vehicle matches the stored identity information, the secondary locking device is controlled to unlock the vehicle door; when the identity information of the rescue personnel outside the vehicle does not match the stored identity information, the secondary locking device is controlled to lock the vehicle door. Those skilled in the art will understand that "the identification device is adapted to authenticate the identity of rescue personnel outside the vehicle" can be achieved through methods such as detecting the vital signs of personnel outside the vehicle using external radar, fingerprint recognition using a fingerprint recognition device on the door handle, voiceprint recognition using an external voice recognition device, or facial recognition using an external facial recognition device. This can prevent children left inside the vehicle from being taken away by unrelated persons when the owner or the guardian of the child is not present after the fuse unlocks the door, further improving the protection of children left behind.

[0051] Specifically, the mechanical triggering device is electrically connected to the fuse function processor 83, and both the first fuse device 51 and the second fuse device 52 are electrically connected to the fuse function processor 83. This allows the fuse function processor 83 to control the fuse function of the first fuse device 51 and the second fuse device 52 after the mechanical triggering device is turned on.

[0052] The life detection device 70 is electrically connected to the first battery 60, and the life detection device 70 is electrically connected to the vehicle body processor 81 and the vehicle body battery 90. In this way, the life detection device 70, the vehicle body processor 81 and the first battery 60 can be powered by the vehicle body battery 90, and the fuse function can be controlled by the vehicle body processor 81.

[0053] The vehicle according to an embodiment of the present invention is described below. The vehicle according to an embodiment of the present invention includes an in-vehicle child protection system 1 according to the above embodiment of the present invention.
