Description

TECHNICAL FIELD

[0002] The existing automobile child safety seats generally adopt a closed foaming material and fabric covering structure to improve safety protection capability. However, such structure generally has the following problems: Poor ventilation, hot and uncomfortable: especially in summer or long time riding, the back and head area is easy to accumulate heat, causing children to sweat and irritability.

[0003] Fan ventilation structure layout is limited: there are already existing technologies that install fans on the seat body part, but these parts are not directly contacted by children, and the actual cooling effect is limited. The headrest and back position actually contacted are difficult to arrange the ventilation structure due to the height adjustment.

[0004] Structural protrusions affect support: if the fan is embedded in the backrest or headrest, it will cause the local thickness to increase, and the fit between the child's body and the seat will decrease, especially after the headrest moves up, the back gap increases, causing insufficient waist support and poor riding comfort.

[0005] In addition, once the foaming structure is formed, its shape and thickness are fixed, and it cannot be dynamically adjusted according to the child's head size, growth stage or sitting posture habit, resulting in insufficient fit for children with small or large body size, and there is a protection gap or compression feeling. Therefore, there is an urgent need for a headrest system that can adapt to the size of a child's head, achieve continuous adaptation for all age groups, and provide effective cushioning in multiple directions, as well as a child safety seat structure that takes into account ventilation comfort and human body support.

[0025] The ventilation assembly 3 is integrated in the lower half of the porous cloth cover 2, and the upper half of the porous cloth cover 2 is connected with the headrest, during the lifting of the headrest, the ventilation assembly 3 can move to adjust its position to ventilate and dissipate heat at different positions; moreover, this design can better adapt to child occupants of different ages or systems, and when the occupant adjusts the position of the headrest according to the height, the position of the ventilation assembly is also adjusted synchronously, so that the headrest and the ventilation assembly are both in a more comfortable and height-adapted state.

[0026] The headrest airbag assembly 4 is arranged between the headrest 1 and the upper half 201 of the cover, which is not only to ensure the safety of the head, but also to match the size and shape of the head of children of different ages by inflating and deflating the airbag, so as to realize the "tailored" wrapping feeling and make the head of the occupant more comfortable. On this basis, through the partition pressure control, balanced and directional buffering and support are provided for the head and neck in the front and side collisions, and multi-dimensional safety protection is realized. That is, the headrest airbag assembly 4 is not a passive trigger airbag, which is different from the existing vehicle safety airbag which is triggered passively for protection in the collision, but actively adjusts the state when the occupant is seated, and provides comfortable support while completing active safety protection after adapting to the head contour.

[0027] The adaptive partition airbag and the ventilated pillow system can also switch (one-key switching) between the "safe support wrapping mode" and the "loose activity mode", and take into account the high safety and the comfort of daily riding. It is suitable for children of all ages (about 9 months to 12 years old), and prolongs the use cycle of the seat.

[0028] The accommodating cavity 5 arranged in the headrest 1 can accommodate the air pump motor 403 more conveniently, avoid the air pump motor 403 from occupying extra space or protruding outside the headrest, and after the headrest safety airbag is installed, the side of the entire headrest facing the occupant is soft and regular, without the feeling of hard objects. The air pump motor needs to be powered to work, and in practice, a pure mechanical manual inflation scheme (manual pressing inflation and deflation) can also be used, without power or one-time gas generator, to ensure the reliability and low maintenance cost of the product during the entire use cycle (0-12 years old).

[0029] Further, as shown in Figure 3 and Figure 4 The ventilating assembly 3 includes an installation frame 301 arranged in the lower half 202 of the cover, the installation frame 301 is provided with an installation groove 302, the installation groove 302 is provided with a air suction device, such as a turbine fan 303, the air outlet of the turbine fan 303 is connected with a wind bag 304, the wind bag 304 is provided with a porous support material 305, and a plurality of air holes 306 are formed in the side of the wind bag 304 facing the occupant; the air holes 306 blow air to the occupant, the turbine fan 303 supplies air to the wind bag 304 to form circulating air.

[0030] The ventilation assembly 3 can suck air from the back of the child safety seat through the above-mentioned setting wind, introduce the air into the headrest / backrest cloth cover through the air bag 304, and flexibly discharge the air from the micro-porous area on both sides of the head / back, forming "no-wind directional ventilation", that is, uniformly diffusing the wind feeling through the air holes and the micro-pores on the porous cloth cover, realizing cold air dispersion and non-direct blowing. In this embodiment, the pore diameter of these micro-pores is 0.8-1.5 mm, and the pore distance is 10-15 mm, realizing flexible air supply.

[0031] The mounting frame 301 can be connected to the sliding linkage body 101 below the headrest 1 to ensure that it can follow the lifting movement of the headrest 1; the mounting groove 302 can accommodate and install the turbine fan 303, and the turbine fan 303 can directly discharge the sucked cold air from the air outlet to the air bag, and finally discharge the air through the air bag 304; the porous supporting material 305 can support the filling of the air bag, so that the air bag 304 has a three-dimensional effect, and can also disperse the air. The form of the air bag is not limited to the mode shown in the drawing, and can be directed to the position in the child safety seat where air blowing is needed, and the air can be blown to the child to realize circulating air.

[0032] Further, the mounting frame 301 is an I-shaped frame, and a pair of mounting grooves 302 are arranged on both sides of the I-shaped frame, and a pair of turbine fans 303 and a pair of air bags 304 are installed in the mounting grooves 302; the air bag 304 includes an air duct 307 connected with the turbine fan, and a bag body connected with the air duct, and the bag body is arranged at a position in the child safety seat where ventilation is needed.

[0033] The I-shaped mounting frame can install a pair of turbine fans, and the air can be introduced to the air bags from the air ducts on both sides, respectively; the air duct 307 can adopt a flexible film air duct or a slidable modular ventilation pipe to improve its flexibility and facilitate arrangement.

[0034] Further, the back of the turbine fan 303 is further connected with the mounting frame 301 through a fiber adhesive tape 308, and the connection stability is further improved, and the wire harness 309 of the turbine fan 303 is led out from the back.

[0035] The air outlet of the turbine fan 303 is provided with an air outlet baffle, which is a structure avoiding position; the front of the turbine fan 303 is provided with a breathable buffer material, such as honeycomb mesh cloth or sandwich cloth, to form a three-dimensional space, so as to increase the air suction area and accelerate the heat dissipation of the back of the child, and the air bags on both sides assist to form a local circulating air to accelerate the heat dissipation.

[0036] Further, in combination with Figures 5 to 7As shown, the headrest airbag assembly 4 includes a middle airbag 401 and a pair of side airbags 402 on both sides of the middle airbag 401, which are located between the headrest 1 and the upper half of the cover 201. The middle airbag 401 and the side airbag 402 are arranged in a non-direct communication manner, are connected to the first air pipe assembly and are independently controlled.

[0037] The headrest airbag assembly 4 is integrated into the cover sandwich layer of the safety seat headrest or is arranged between the cover and the headrest body. The headrest airbag assembly 4 includes at least one middle airbag 401 and two side airbags 402, which together form a three-sided wrapping structure for the child's head. The partitioned airbags can better wrap the head and can be adapted to children of different head sizes. The airbags can be inflated to wrap the head and improve safety, or can be used without inflation without affecting head movement.

[0038] The headrest airbag assembly 4 can be linked with the headrest height adjustment mechanism, and the installation position and layout thereof are matched with the up-down adjustment path of the safety seat headrest. When the headrest is raised to adapt to a taller child, the overall wrapping area of the headrest airbag assembly is synchronously moved upward, ensuring that the key protection area of the head is always aligned.

[0039] The headrest airbag assembly 4 also adopts partitioned inflation for regulation and control, and the core lies in the built-in air flow distribution and control valve. Synchronous differential pressure inflation is realized through air flow distribution and valve control: when inflated, the gas preferentially or with a larger flow enters the side airbags 402 on both sides, so that the side airbags 402 are rapidly inflated to form lateral support. The middle airbag 401 is then inflated at a lower pressure to provide frontal cushioning and avoid excessive pressure on the child's face.

[0040] Specifically, the first air pipe assembly includes a main air pipe 404 connected to the air pump motor 403. The main air pipe 404 is connected with a pressure relief electromagnetic valve 405 (through one or more independent / linked pressure relief valves, all airbags can be rapidly deflated synchronously, or specific areas can be fine-tuned). The end of the main air pipe 404 is connected with a middle air pipe 407 and a side air pipe 408 through a three-way electromagnetic valve 406. The side air pipe 408 is Y-shaped and is connected to a pair of side airbags 402.

[0041] When the air pump motor 403 is working, the air pump inlet is in communication with the atmosphere, and the air pump pumps out the pressure gas to ventilate the middle air pipe 407 and the side air pipe 408 through the main air pipe 404, so as to ventilate the middle air bag 401 and the side air bag 402. During the air inlet process, the pressure relief electromagnetic valve 405 is in a closed state, and the air bag will be inflated to lift the headrest (headrest) height. When it is needed to lower the headrest (headrest) height, the air pump motor 403 is not working, and the pressure relief electromagnetic valve 405 is opened. The pressure gas of the air bag is communicated with the atmosphere through the air pipe, and the air is discharged to lower the headrest support height.

[0042] The three-way electromagnetic valve 406 can be a two-position three-way electromagnetic valve, and two outlets thereof are respectively connected with two independent partition air bags. When the middle air bag 401 is filled with air, the two-position three-way electromagnetic valve is in a middle air bag conduction position, and the air discharge only needs to open the pressure relief electromagnetic valve. Similarly, when the side air bags 402 on both sides are filled with air, the two-position three-way electromagnetic valve is in a two-side air bag conduction position.

[0043] In some embodiments, the present headrest system further comprises a removable waist support 6 arranged on the base of the child safety seat. When the back of the waist support 6 abuts against the backrest of the child safety seat, the lower half of the cloth cover 202 covers the front of the waist support to ventilate.

[0044] The ventilation assembly 3 is arranged in the lower half of the cloth cover of the headrest. When a small child of 0-15 months old sits in the seat, a waist support 6 is arranged in the seat, and the lower half of the cloth cover 202 is covered on the waist support 6 as the ventilation of the waist support. In this way, the seat can meet the ventilation needs of small and large children. One set of ventilation assembly can be shared, which is simple and practical.

[0045] In some embodiments, as shown in Figure 8 The present headrest system further comprises a waist and back difference elimination air bag assembly arranged in the back area of the child safety seat. The waist and back difference elimination air bag assembly comprises a plurality of air bag strips 7, the air bag strips 7 are respectively connected with a shared quick plug connector 10 through an air inlet pipeline 8 provided with a one-way valve 9, the shared quick plug connector 10 is connected to an air pump motor, and the air bag strips 7 are further provided with air discharge holes 11, and the air discharge holes 11 are connected with air discharge devices (such as air discharge knobs) or plugs.

[0046] Because the headrests of different ages of children are adapted to different heights, a difference will naturally be formed at the lowermost end of the headrest cloth cover. This difference will cause the waist and back of the child to be not effectively supported, which affects the comfort. By arranging the waist and back difference elimination air bag assembly, the partition filling and intelligent compensation of the waist support can be well achieved, the problem of empty waist after the headrest is lifted can be solved, and when the headrest is lowered, the waist and back difference elimination air bag assembly can be retracted or discharged to restore flatness, without affecting the normal use of other functions.

[0047] The lumbar and back gap elimination air bag assembly is filled by multiple independent air bags, divided into three independent air bag strips 7, located on the chair body cover, at the lower end of the headrest 1, the headrest 1 is adjusted upwards, the exposed air bag strip 7 is inflated, and the air bag is deflated when it is overlapped. The air inlet pipe of each of the three independent air bag strips 7 is provided with a one-way valve 9 to ensure that the gas is locked after being filled and cannot be discharged. Each air bag strip 7 has a deflation button or a cover, which can be used to control the gas of the air bag that is not needed. The common air inlet pipe has a quick connector, which can be directly connected to the air source pipe, for example, the air source of the headrest air bag assembly can be shared.

[0049] The backrest area of the child safety seat is also provided with a temperature sensor to monitor the temperature of the backrest area in real time and feed back the temperature data to the controller; The headrest can send adjustment signals to the controller through displacement sensors (such as sliding rail potentiometer detection sensors) during the lifting adjustment process, so that the controller can issue corresponding operation instructions according to these feedbacks.

[0050] The side area of the child safety seat can also be provided with a human-computer interaction system 12 (such as Figure 9 The human-computer interaction system 12 includes a touch screen, a microphone, a speaker, and various keys electrically connected to the controller, so as to operate and control various functions of the seat.

[0051] Embodiment 3: Provide a control method of a ventilation and air bag adaptive adjustment headrest and a child safety seat.

[0052] The control method includes voice control, APP program control, or physical human-computer interaction control, which is as follows: Voice control: control the start and stop of the turbine fan and the air volume, and the start and stop of the air pump motor and the air bag air inlet amount through voice dialogue; APP program control: virtual buttons appear on the interface to control the start and stop of the turbine fan and the air volume; Different partition air bag display icon buttons control the start and stop of the air pump motor and the air bag air inlet amount; Physical or touch button and touch screen display control: physical or touch button is provided on the side of the seat, one way is to touch the screen to achieve turbo fan mode, multiple air bag mode switching, through up and down button operation instruction, control turbo fan start and stop and air volume, also air pump motor start and stop and air bag air intake.
