In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Unless otherwise specified, the front-to-back direction in the present application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0039] Reference below Figure 1-Figure 5A control method for a child seat 100 according to an embodiment of the present invention is described. The control method can perform intelligent control on the inflatable child seat 100, realize automatic inflation and adjustment of the seat to meet the riding needs of different users, improve the convenience of use and the riding comfort and safety of the user, improve the intelligence of the entire vehicle, and improve the utilization rate of seats in the cabin.

[0040] like Figure 1-5 As shown, according to a control method of a child seat 100 according to an embodiment of the present invention, the child seat 100 is an inflatable seat and includes a backrest airbag 1 and an armrest airbag 2 .

[0041] The child seat 100 can be used by children and adults. When an adult uses the child seat 100 daily, the child seat 100 may not be inflated, but used as a normal car seat for daily use. When a child uses the child seat 100, the child seat 100 may be inflated to ensure stability and protect safety. The backrest airbag 1 and the armrest airbag 2 can be inflated and deflated to meet the different needs of different users, and the inflation amount can be flexibly adjusted to provide personalized adjustments for children of different ages and body shapes, provide better support and comfort, and wrap the child in the airbag. In the event of a collision, the airbag can provide a certain buffer space to reduce the impact force on the child, thereby ensuring the child's riding safety.

[0042] Therefore, the child seat 100 can be flexibly adjusted according to different types of users, that is, selectively inflated, to meet the usage needs of different users, and the safety and comfort of children in the process of riding can be improved. The inflation amount can be flexibly adjusted according to the actual situation of the child, so as to provide more intimate and comprehensive protection for the child. The inflatable seat does not need to be installed and disassembled, but only needs to be inflated and deflated, which greatly improves the convenience and does not need to occupy storage space. It avoids the installation and disassembly inconvenience and safety hazards brought by the traditional detachable child seat 100, and improves the utilization rate of the seats in the cabin.

[0043] Control methods include:

[0044] Obtaining a child seat 100 opening signal;

[0045] After receiving the opening signal of the child seat 100, controlling the backrest airbag 1 to inflate;

[0046] Obtain the user's vital signs information;

[0047] According to the vital sign information, the armrest airbag 2 is controlled to be inflated.

[0048] Furthermore, the control method includes:

[0049] First, an unlocking signal of the vehicle and an opening signal of the child seat 100 are obtained.

[0050] Specifically, when the vehicle is unlocked and in an unlocked state, an unlock signal can be sent, and when the vehicle owner or passenger sends an opening command for the child seat 100, in practice, the vehicle owner or passenger can choose remote control, such as mobile phone, touch screen, button or voice control to send an opening signal for opening the child seat 100. At this time, the vehicle's unlock signal and the child seat 100 opening signal can be obtained, and the child seat 100 can be further inflated for use.

[0051] Secondly, after receiving the unlocking signal and the opening signal of the child seat 100, the backrest airbag 1 is controlled to be inflated.

[0052] Specifically, after the system receives the unlocking signal confirming that the vehicle is unlocked, and receives the opening signal of the child seat 100, it first controls the backrest airbag 1 to inflate. When the backrest airbag 1 meets the support conditions of the child, it can stop inflating. At this time, the armrest airbag 2 is in a low-pressure state, and the child can be conveniently and safely placed on the child seat 100.

[0053] The backrest airbag 1 is the main supporting part for children when they are sitting. Inflating it first can ensure that the child has a stable supporting environment when placed on the child seat 100, which can provide stable support for the child's back and head, thereby ensuring that the child can maintain a correct sitting posture when sitting, thereby improving the comfort and safety of the child.

[0054] It should be noted that the inflation volume of the backrest airbag 1 can be adjusted so that the backrest airbag 1 can adapt to children of different heights to ensure that their backs and heads can be fully supported. In addition, the softness of the backrest airbag 1 can also increase the riding comfort.

[0055] And when the system does not obtain or receive the child seat 100 start signal, the child seat 100 is in the default state, that is, the backrest airbag 1 and the armrest airbag 2 are not inflated, the backrest airbag 1 and the armrest airbag 2 can be hidden in the cabin to save space. At this time, the seat can be used for daily adult use.

[0056] Thirdly, a user's placement signal on the seat back is obtained.

[0057] Specifically, when a child is placed on the child seat 100, the system can obtain the user's placement signal on the seat back through sensors, etc., so as to confirm that the child is actually placed on the seat and proceed to the next step.

[0058] Then, after receiving the placement signal, the user's vital sign information is obtained.

[0059] Specifically, after receiving the placement signal to confirm that the child has sat on the seat, the child's vital sign information can be obtained through the sensor, so that the child seat 100 can be further adjusted according to the vital sign information.

[0060] Finally, according to the vital sign information, the armrest airbag 2 is controlled to inflate.

[0061] Specifically, the armrest airbags 2 are located on both sides of the seat, which can provide stable support for the child's arms. After the armrest airbags 2 are inflated, they can limit the movement range of the child on the child seat 100, thereby preventing accidental falls during driving of the vehicle.

[0062] After obtaining the child's vital information, the armrest airbag 2 can be controlled to inflate, and the inflation degree of the armrest airbag 2 can be judged and adjusted according to the obtained vital information. For example, when the child is larger, the inflation amount of the armrest airbag 2 can be increased to provide a more stable side support; on the contrary, when the child is smaller, the inflation amount of the armrest airbag 2 can be reduced to avoid excessive restriction and restraint, thereby ensuring that the armrest airbag 2 provides sufficient support for the child's arms and will not cause discomfort and restraint to the child due to over-inflation, thereby further improving the riding comfort and safety.

[0063] Therefore, the inflation state of the backrest airbag 1 and the armrest airbag 2 is automatically adjusted to achieve automated and personalized adjustment of the child seat 100, thereby providing a more stable and safe riding environment for children and reducing the risk of falling due to bumps or sudden stops during vehicle driving; and the inflation state of the armrest airbag 2 can be flexibly adjusted according to the child's physical information, so as to be compatible with users of different body shapes, and the child can be safely and comfortably fixed in the child seat 100, thereby improving the safety and comfort of the child during the ride; the child seat 100 is intelligently controlled by this control method without manual adjustment, thereby achieving a higher degree of vehicle intelligence, and the seat can also be used by adults for daily use without disassembly, thereby improving the user experience and the utilization rate of seats in the cabin.

[0064] According to the control method of the child seat 100 in the embodiment of the present invention, the inflatable child seat 100 is intelligently controlled to realize automatic inflation and adjustment of the seat to meet the riding needs of different users, thereby improving the convenience of use and the riding comfort and safety of the user. There is no need to manually adjust and disassemble the seat, and it can be used by adults in daily life, thereby improving the overall user experience, improving the intelligence of the entire vehicle, and improving the utilization rate of seats in the cabin.

[0065] In some embodiments, controlling the armrest airbag 2 to inflate according to the vital sign information includes: determining the current age group of the user according to the vital sign information, and controlling the armrest airbag 2 to inflate in a mode matching the current age group according to the current age group.

[0066] That is to say, after obtaining the vital sign information, the current age group of the user can be judged based on the obtained vital sign information, so that the inflation mode of the armrest airbag 2 can be flexibly controlled according to the different body shapes of users of different age groups. That is, the amount of gas and pressure distribution in the armrest airbag 2 can be controlled according to the current age group to achieve different support effects to adapt to the body shape and comfort requirements of users of different age groups.

[0067] In practice, when it is determined that the user's current age is older, the armrest airbag 2 can be set to a softer support mode. When it is determined that the user's current age is younger, the armrest airbag 2 can be set to a more stable support mode to ensure its safety.

[0068] In some embodiments, the armrest airbag 2 includes a plurality of airbag compartments, and controlling the armrest airbag 2 to inflate in a mode matching the current age group includes:

[0069] When the current age group is in the first stage, the armrest airbag 2 is controlled to be inflated with a first set number of airbag compartments; when the current age group is in the second stage, the armrest airbag 2 is controlled to be inflated with a second set number of airbag compartments; and when the current age group is in the third stage, the armrest airbag 2 is controlled to be inflated with a third set number of airbag compartments.

[0070] Among them, the ages corresponding to the first stage, the second stage and the third stage increase successively, and the numbers corresponding to the first set number, the second set number and the third set number gradually decrease.

[0071] Specifically, each airbag compartment can be inflated or deflated, and the size of each airbag compartment can be set to be the same or different to facilitate adjustment of the shape of the armrest airbag 2, and each airbag compartment can be deflated or inflated individually. In other words, the number of airbag compartments that are inflated can be flexibly increased or decreased to finely adjust the shape and size of the overall armrest airbag 2 to better adapt to the body shapes and sitting postures of different users.

[0072] When it is determined that the user's current age is in the first stage, that is, the youngest age, his body is smaller and he needs an armrest with stronger support to ensure his safety. Therefore, the armrest airbag 2 can be controlled to be inflated with the first set number, that is, the least number of airbag compartments are activated, so that the expansion volume of the armrest airbag 2 can be larger, so that the armrest airbag 2 can fit closely to the arm of the user of the first stage age, reducing the gap, and providing sufficient wrapping and stability for the user of the first stage age.

[0073] When it is determined that the user's current age is in the second stage, that is, he is older, he needs a certain degree of comfort and range of activities, and his body shape is also larger than that of the users in the first stage, so the seat occupies a larger space. Therefore, the armrest airbag 2 can be controlled to inflate with a second set number, that is, a smaller number of airbag compartments are enabled relative to the first set number, so that the expanded volume of the armrest airbag 2 can be smaller than the volume to be inflated for users of the first stage age, thereby increasing the range of activities, reducing the sense of oppression on the user, and helping to better suit users of the second stage age.

[0074] When it is determined that the user's current age is in the third stage, that is, the oldest, his range of activities is also larger, and his body size is larger than that of users in the first and second stages. The seat space occupied is also correspondingly increased. Therefore, the armrest airbag 2 can be controlled to a third set number, that is, the inflation amount of the airbag partition is further reduced, thereby further reducing the expanded volume of the armrest airbag 2, providing a larger range of activities for users in the third stage.

[0075] Therefore, by flexibly adjusting the set inflation quantity of the airbag interlayer, the size and shape of the inflation and deflation area of ​​the armrest airbag 2 can be flexibly adjusted, thereby changing the child's range of activities and the degree of wrapping of the armrest airbag 2 to adapt to children of different age groups.

[0076] In some embodiments, controlling the armrest airbag 2 to inflate in a mode matching the current age group includes:

[0077] When the current age group is in the first stage, the armrest airbag 2 is controlled to be inflated with the first set air pressure; when the current age group is in the second stage, the armrest airbag 2 is controlled to be inflated with the second set air pressure; and when the current age group is in the third stage, the armrest airbag 2 is controlled to be inflated with the third set air pressure.

[0078] Among them, the ages corresponding to the first stage, the second stage and the third stage increase successively, and the air pressure values ​​corresponding to the first set air pressure, the second set air pressure and the third set air pressure gradually decrease.

[0079] Specifically, when the inflation pressure of the armrest airbag 2 is higher, it is more solid and can provide stronger support. When the air pressure is lower, it is softer and more comfortable, but the support will be reduced accordingly, and the user can move within a certain range.

[0080] When it is determined that the user's current age is in the first stage, that is, the youngest age, he needs an armrest with stronger support force to ensure his safety. Therefore, the armrest airbag 2 can be controlled to be inflated with a first set air pressure. Even if the air pressure value in the armrest airbag 2 is relatively large, the armrest airbag 2 can be made more solid as a whole, with stronger support force, thereby providing sufficient support and protection for the user, and at the same time will not cause discomfort to the user due to excessive air pressure.

[0081] When it is determined that the user's current age is in the third stage, that is, the oldest, his range of activities is also larger, his body size is larger than that of users in the first and second stages, and the seat space occupied is also correspondingly increased. Therefore, the armrest airbag 2 can be controlled to be inflated with the second set air pressure, that is, the air pressure value in the armrest airbag 2 is lower than the second set air pressure, so that the armrest airbag 2 as a whole can maintain sufficient supporting force while increasing softness and comfort, so as to better suit users of the second stage of age.

[0082] When it is determined that the user's current age is in the third stage, that is, the oldest, his range of activities is also larger, and his body size is larger than that of users in the first and second stages. The seat space occupied is also correspondingly increased. Therefore, the armrest airbag 2 can be controlled to inflate with the third set air pressure. Even if the air pressure value in the armrest airbag 2 is the lowest, the armrest airbag 2 will be softer and more comfortable while providing sufficient support, reducing the feeling of oppression and restraint, thereby improving the riding comfort and safety of users in the second stage.

[0083] Therefore, by flexibly adjusting the inflation pressure value of the armrest airbag 2, the supporting force of the airbag can be finely adjusted to adapt to children of different age groups, which not only ensures that the armrest airbag 2 has a certain degree of support, but also improves comfort and safety.

[0084] In some embodiments, the age of the first stage is 0 to 1 years old, the age of the second stage is 1 to 4 years old, and the age of the third stage is 4 to 14 years old.

[0085] That is to say, in the current age group of 0 to 1 years old, that is, the infant period, the infant has less autonomous consciousness and the smallest body size, and requires an armrest airbag 2 with a higher safety factor, stronger support and stronger wrapping. Therefore, the air pressure value of the first set air pressure of the armrest airbag 2 can be set to the minimum to ensure that the armrest airbag 2 has sufficient supporting force to fix the infant. At the same time, the number corresponding to the first set number of the armrest airbag 2 is set to the maximum to ensure that the armrest airbag 2 can fit the infant and wrap the infant tightly, thereby protecting the infant and preventing it from falling.

[0086] The current age group is 1 to 4 years old, that is, the toddler period. The growth and development speed of toddlers is faster, they occupy a larger space and have a certain ability to move. They need a certain range of activities. They need an armrest airbag 2 with a certain comfort and a larger space for activities while ensuring safety. Therefore, the air pressure value of the second set air pressure of the armrest airbag 2 can be set to a smaller value to ensure that the armrest airbag 2 has sufficient supporting force to fix the toddler while also increasing the softness and comfort. At the same time, the number corresponding to the second set number of the armrest airbag 2 is set to a smaller number so that the toddler can move within a safe range.

[0087] When the current age group is between 4 and 14 years old, that is, the older children, the growth and development speed is faster, the space occupied is larger and the required range of activities is larger. It is necessary to have an armrest airbag 2 with a certain comfort and a larger activity space while ensuring safety. Children of this age group are more active. Therefore, the air pressure value of the third set air pressure of the armrest airbag 2 can be set to the minimum to ensure that the armrest airbag 2 has sufficient supporting force to fix the children to ensure their safety and stability, and also increases a certain softness and comfort. At the same time, the number corresponding to the third set number of the armrest airbag 2 is set to the minimum to adapt to the child's body shape so that it can move within a safe range.

[0088] In this way, children aged 0 to 14 years old can be safely fixed, ensuring comfort and safety.

[0089] In some embodiments, the vital sign information includes gravity information, and determining the current age group of the user based on the vital sign information includes: obtaining gravity information of the user on the child seat 100, and determining the current age group of the user based on the gravity information.

[0090] Specifically, the gravity information of the user sitting on the child seat 100 can be obtained through the sensor, and the obtained gravity information can be analyzed and processed to extract features useful for determining the age group, and the gravity information can be compared with preset age group features to determine the user's current age group.

[0091] In some embodiments, controlling the armrest airbag 2 to inflate according to the vital sign information includes:

[0092] The user's movement status, heart rate information and breathing information are obtained; based on the movement status, heart rate information and breathing information, whether the user is in a sleeping state is determined; after determining that the user is in a sleeping state, the armrest airbag 2 is controlled to inflate in a mode matching the sleeping state.

[0093] Specifically, the user's movement status, heart rate information and breathing information can be obtained in real time through sensors, and the differences in the user's movement status, heart rate information and breathing information when they are awake and asleep can be analyzed to determine whether the user on the child seat 100 is in a sleeping state. When it is determined that the user is in a sleeping state, the system will control the inflation mode of the armrest airbag 2 to adapt to the sleeping needs. In other words, by controlling the inflation amount of the airbag compartment and the inflation pressure of the armrest airbag 2, the seat angle can be coordinated to allow the user to fall asleep in a comfortable posture, thereby further improving the intelligence level of the child seat 100.

[0094] In some embodiments, the control method further comprises:

[0095] After receiving the unlocking signal and not receiving the opening signal of the child seat 100, the backrest airbag 1 and the armrest airbag 2 are controlled to be deflated.

[0096] Specifically, when the vehicle is unlocked and an unlock signal is sent, and the owner or passenger does not issue an opening command for the child seat 100, that is, does not issue an opening signal for the child seat 100, at this time, the system receives the unlock signal but does not receive the opening signal for the child seat 100, and can control the backrest airbag 1 and the armrest airbag 2 to deflate at the same time and return to an uninflated state, thereby restoring the backrest airbag 1 and the armrest airbag 2 to the default state for daily use by adults.

[0097] In some embodiments, the child seat 100 is further provided with a sunshade 3, which can be disposed above the child seat 100. When encountering weather with strong sunlight, the human body temperature will rise, and direct sunlight will cause damage to the eyes, especially when the vehicle is traveling outdoors in a strong sunlight environment. The sunshade 3 can effectively block the sunlight, protect the user's eyes from ultraviolet rays and other harmful light, and reduce the temperature rise in the car, thereby providing the user with a cooler and more comfortable riding environment.

[0098] The control method also includes: obtaining current weather conditions.

[0099] Specifically, the current weather information can be obtained in real time through GPS, sensors, APP applications, weather detection equipment, vehicle communication network, etc. For example, the current weather conditions can be judged based on weather information such as sunlight intensity, temperature, humidity, etc., and the weather state can be judged as sunny, cloudy or rainy.

[0100] According to the current weather conditions, the sunshade 3 is controlled to move relative to the child seat 100 , and the sunshade 3 is made to shield the eyes of the user in the child seat 100 .

[0101] Specifically, after receiving the weather conditions, for example, when the weather status shows that it is sunny or the temperature is high, Figure 3 As shown, the sun visor 3 is controlled to move relative to the child seat 100 so that the sun visor 3 automatically lowers to shield the user's eyes, thereby effectively protecting the user's eyes. When the weather conditions are cloudy or rainy, the sun visor 3 is controlled to move relative to the child seat 100 so that the sun visor 3 automatically rises away from in front of the user's eyes.

[0102] In some embodiments, the control method further comprises:

[0103] Get the vehicle's locking signal.

[0104] Specifically, when the vehicle door is closed and the vehicle enters a locked state, a locking signal may be issued.

[0105] After receiving the locking signal, gravity information on the child seat 100 is detected.

[0106] Specifically, after receiving the locking signal, the system can detect gravity information on the child seat 100 through sensors and the like.

[0107] When it is determined based on the gravity information that a child is trapped in the child seat 100, an alarm signal is issued.

[0108] Specifically, the detected gravity information can be analyzed and compared to determine whether there is a child stranded in the child seat 100 when the vehicle is in a locked state. When it is determined that a child is stranded in the child seat 100, an alarm signal is issued, such as a sound alarm, a light alarm, or a remote notification sent through a connection with the owner's mobile phone, thereby reminding the owner or people around the vehicle to prevent the child from being forgotten in the vehicle.

[0109] The present invention also provides a control system of the child seat 100 .

[0110] According to the control system of the child seat 100 of the embodiment of the present invention, the control system is applicable to the control method of the child seat 100 of any of the above embodiments, and the control system includes: the child seat 100, an inflation valve, a deflation valve and a control module.

[0111] The child seat 100 is used for children or adults to sit on. Figure 1 As shown, the child seat 100 is an inflatable seat and includes a backrest airbag 1 and an armrest airbag 2. The backrest airbag 1 and the armrest airbag 2 can be intelligently inflated or deflated according to the body shape and posture of the user to provide the user with optimal riding comfort.

[0112] In actual design, the surfaces of the backrest airbag 1 and the armrest airbag 2 can be made of waterproof, heat-resistant, anti-slip and anti-cut materials to ensure the safety of the airbag to the greatest extent.

[0113] The backrest airbag 1 and the armrest airbag 2 are each provided with an inflation valve and a deflation valve, that is, the inflation or deflation process of the backrest airbag 1 and the armrest airbag 2 can be precisely controlled by controlling the inflation valve and the deflation valve, so that the backrest airbag 1 and the armrest airbag 2 can reach different pressure states.

[0114] The control module is electrically connected to the inflation valve and the deflation valve respectively, that is, the control module can send control signals to the inflation valve and the deflation valve to achieve precise control of the inflation or deflation of the airbag. When the inflation valve receives the control signal, the inflation valve can inflate the backrest airbag 1 or the armrest airbag 2; when the deflation valve receives the control signal, the deflation valve can deflate the backrest airbag 1 or the armrest airbag 2.

[0115] Therefore, the inflation valve and the deflation valve are controlled by the control module to realize the inflation or deflation of the backrest airbag 1 and the armrest airbag 2, so that the pressure state of the backrest airbag 1 and the armrest airbag 2 can be flexibly adjusted, and the intelligent and refined control of the inflatable child seat 100 is realized, providing children with a safer, more comfortable and convenient riding experience.

[0116] In some embodiments, the control system of the child seat 100 also includes a gravity sensor, which is installed on the child seat 100 and is used to detect the gravity information of the user. The control module is electrically connected to the gravity sensor to control the inflation valve and the deflation valve according to the gravity information.

[0117] Specifically, the gravity sensor can be installed under the seat cushion or under the backrest of the child seat 100 to ensure that the gravity sensor can accurately sense the user's gravity information. The gravity sensor can detect the user's gravity information by detecting the weight distribution and changes on the child seat 100 in real time, and the gravity sensor can transmit the detected gravity information to the control module. The control module receives the gravity information transmitted by the gravity sensor and performs real-time analysis to determine whether there is a child sitting on the seat and determine the child's current age group.

[0118] When the control module determines that a child is sitting on the child seat 100, the inflation amount of the backrest airbag 1 and the armrest airbag 2 can be adjusted by controlling the inflation valve and the deflation valve according to the current age of the child, that is, according to the different weights of the child, so that the backrest airbag 1 and the armrest airbag 2 can reach different pressure states to ensure the child's comfort. For example, a corresponding threshold value can be set for the gravity sensor. If the gravity sensor senses that the child of a younger age group exceeds the threshold value, the control module controls the deflation valve to work and reduce the inflation amount in the airbag, thereby providing the child of the younger age group with a more comfortable activity space, reducing the degree of wrapping and the feeling of being too tight; if the gravity sensor senses that the child of the younger age group is less than the threshold value, the control module controls the inflation valve to increase the inflation amount in the airbag, thereby providing the child of the younger age group with better support and improving the degree of wrapping.

[0119] In other embodiments, the control system of the child seat 100 further includes a pressure sensor. Pressure sensors are provided in the backrest airbag 1 and the armrest airbag 2. The control module is electrically connected to the pressure sensor to control the inflation valve and the deflation valve according to the pressure information.

[0120] Specifically, the pressure sensors in the backrest airbag 1 and the armrest airbag 2 can detect the pressure information in the backrest airbag 1 and the armrest airbag 2 in real time, and transmit the pressure information to the control module in real time. The control module receives the pressure information transmitted by the pressure sensor and performs real-time analysis to determine whether the air pressure values ​​in the backrest airbag 1 and the armrest airbag 2 reach the set air pressure values. For example, if the pressure sensor senses that a younger child sits on the seat and the air pressure value in the airbag does not reach the set air pressure value, the control module controls the deflation valve to reduce the air pressure in the airbag, thereby providing the younger child with a more comfortable space for activities and reducing the degree of wrapping and the feeling of being too tight and restrained; if the pressure sensor senses that a younger child sits on the seat and the air pressure value in the airbag is less than the set air pressure value, the control module controls the inflation valve to increase the air pressure in the airbag, thereby providing the younger child with better support and improving the degree of wrapping.

[0121] Therefore, the pressure in the backrest airbag 1 and the armrest airbag 2 can be adaptively adjusted through the gravity sensor and the pressure sensor, so that the child seat 100 can better adapt to children of different body shapes and ages, and improve the riding comfort and safety. The gravity sensor and the pressure sensor detect and adjust the pressure value of the airbag and the armrest airbag 2 in real time, and adjust the supporting force in time, which can provide more stable and safe support for children in emergency situations and reduce injuries caused by collisions or sudden braking.

[0122] In some embodiments, the control system of the child seat 100 further includes a radar sensor for detecting vital signs of the user, and the control module is electrically connected to the radar sensor to control the inflation valve and the deflation valve according to the vital signs.

[0123] Specifically, the radar sensor can be installed in the vehicle cabin. The radar sensor can detect the user's vital signs information, namely the user's movement status, heartbeat information and breathing information, in real time by analyzing the difference between the transmitted signal and the received signal under different circumstances, and transmit the detected vital signs information of the user to the control module. The control module analyzes the difference in the user's vital signs when the user is awake and asleep, so as to determine whether the user on the child seat 100 is in a sleeping state. When it is determined that the user is in a sleeping state, the control module can control the inflation valve and the deflation valve to adjust the inflation amount and pressure state in the armrest airbag 2 and the backrest airbag 1, and cooperate with the seat angle to allow the user to fall asleep in a comfortable posture, thereby further improving the intelligence level of the child seat 100.

[0124] For example, when it is detected that the child's breathing becomes rapid or the heartbeat accelerates, the child may be in a state of discomfort or tension. At this time, the control module can control the deflation valve to appropriately deflate the backrest airbag 1 and the armrest airbag 2 to provide more comfortable support.

[0125] In some embodiments, the backrest airbag 1 and the armrest airbag 2 each include a plurality of airbag compartments, each airbag compartment is provided with an intelligent switch, and the control module is electrically connected to the intelligent switch to control the intelligent switch to be turned on or off.

[0126] Specifically, the size and number of multiple airbag compartments in the backrest airbag 1 and the armrest airbag 2 may be different, and they may work independently or in coordination, that is, each airbag compartment in the backrest airbag 1 and the armrest airbag 2 may be inflated or deflated independently, or may be inflated or deflated simultaneously, and each airbag compartment is provided with an intelligent switch, and the inflation state of each airbag compartment can be flexibly controlled by controlling the intelligent switch in each airbag compartment, and after receiving the output signal from the gravity sensor, the pressure sensor and the radar sensor, the control module can transmit the output signal to each intelligent switch through analysis, so as to accurately control the opening or closing of each intelligent switch through the control module to control the inflation state of each airbag compartment, thereby increasing or decreasing the shape size and pressure size of the overall airbag, so as to reduce or increase the space of the child seat 100 and the supporting force of the overall airbag, and further change the child's range of activities and the degree of wrapping of the airbag.

[0127] It should be noted that when the intelligent switch is in the on state, the airbag compartment can be inflated, and correspondingly, when the intelligent switch is in the off state, the airbag compartment cannot be inflated. The more inflated airbag compartments there are, that is, the larger the area where the backrest airbag 1 and the armrest airbag 2 can be inflated, the larger the inflated volume will be, and the smaller the space of the corresponding child seat 100 will be, the smaller the range of activities of the child will be; the fewer inflated airbag compartments there are, that is, the smaller the area where the backrest airbag 1 and the armrest airbag 2 can be inflated, the smaller the inflated volume will be, and the larger the space of the corresponding child seat 100 will be, and the larger the range of activities of the child will be, so that the overall airbag shape can be precisely controlled by adjusting the inflated area of ​​the airbag to better adapt to different children.

[0128] The pressure information can be detected by the pressure sensor so that the control module can control the pressure of the airbag partition, and the gravity information can be detected by the gravity sensor so that the control module can control the inflation amount of the airbag partition.

[0129] In some embodiments, the child seat 100 is also provided with a sunshade bracket, which can be movably mounted on the child seat 100. The sunshade bracket is equipped with a sunshade cover 3. The control module is used to control the movement of the sunshade bracket relative to the child seat 100 to selectively shield the user's eyes.

[0130] Specifically, the sunshade bracket can be arranged above the child seat 100, and the sunshade 3 can be installed on the sunshade bracket, so that when the sunshade bracket moves relative to the child seat 100, the sunshade 3 is driven to move, so that the sunshade 3 can cover the user's eyes or leave the user's eyes. The sunshade bracket can also be disassembled to facilitate the installation and maintenance of the sunshade bracket and the sunshade 3.

[0131] Among them, the control module can analyze the received weather conditions to intelligently control the movement of the sunshade bracket relative to the child seat 100 to selectively shield the user's eyes. For example, when the weather conditions are displayed as sunny or the temperature is high, the sunshade 3 can be used to shield the user's eyes. When the weather conditions are displayed as cloudy or rainy, the sunshade 3 can be moved away from the user's eyes, thereby automatically adjusting the sunshade 3 to effectively protect the user's eyes and avoid damage to the eyes from direct sunlight and ultraviolet rays.

[0132] Of course, the sunshade bracket can also be manually adjusted so that the sunshade 3 covers the user's eyes, which is flexible and convenient for users to use.

[0133] In actual design, the sunshade 3 may adopt a semi-enclosed mesh structure to ensure air permeability and the user's range of movement.

[0134] The present invention also provides a vehicle.

[0135] The vehicle according to the embodiment of the present invention includes the control system of the child seat 100 of any of the above embodiments. Among them, by intelligently controlling the inflatable child seat 100, the seat is automatically inflated and adjusted to meet the riding needs of different users, thereby improving the convenience of use and the riding comfort and safety of the user. There is no need to manually adjust and disassemble the seat, and it can be used by adults in daily life, thereby improving the overall user experience, improving the intelligence of the entire vehicle, and improving the utilization rate of seats in the cabin.
