Therefore, it cannot be understood as a limitation on the present utility model.

[0038] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0039] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0040] As mentioned in the background technology, a child safety seat is a safety device specially designed for children of different ages or body shapes. When installed in a car, it can effectively improve the safety of children riding in a car. Currently, more and more parents are paying attention to the safety of children riding in seats, and are also particularly concerned about the comfort of children riding in child safety seats.

[0041] In the prior art, the comfort level of child safety seats is not high, especially when driving with children in hot summer, the comfort level of child safety seats is poor.

[0042] In view of this, please refer to Figure 1-Figure 10 , Figure 8-Figure 10 The direction of the arrow in the figure can be understood as the direction of gas flow. The child safety seat provided in the embodiment of the utility model can solve this problem, which will be described in detail below.

[0043] Please refer to Figure 1 and Figure 2 as well as Figure 8 The utility model provides a child safety seat, which includes a seat back 100, a first fan 200 and a first wind pressure structure 300, wherein the first fan 200 is disposed on the seat back 100, the first wind pressure structure 300 is disposed on the seat back 100, and the first wind pressure structure 300 is provided with a first wind gathering channel 302.

[0044] Among them, the first wind gathering channel 302 is used to generate wind pressure by gathering the wind of the first fan 200 when the first fan 200 is in a blowing state, thereby forming a wind gathering effect and increasing the wind pressure of the gas blown into the chair back 100 by the first fan 200. The first wind gathering channel 302 is used to make the gas in the chair back 100 be sucked into the first wind gathering channel 302 when the first fan 200 is in a sucking state.

[0045] Since the first wind gathering channel 302 forms a wind gathering effect, the wind blown out by the first fan 200 is pressurized by the first wind gathering channel 302, so that the wind volume and wind pressure are increased when discharged, and blown into the chair back 100, thereby improving the riding comfort of children and reducing heat and dryness.

[0046] At the same time, when the first fan 200 sucks air, the gas in the seat back 100 is sucked into the first wind gathering channel 302. At this time, the first wind pressure structure 300 is like a straw device. After the air in the first wind pressure structure 300 is emptied, a vacuum space is formed, and the air pressure will be lower than the external air pressure. In this way, the air in the seat back 100 will be sucked into the first wind pressure structure 300, forming a siphon effect, increasing the speed of air circulation, and being sucked in by the first wind pressure structure 300 and discharged out of the seat back 100 by the first fan 200. At this time, the heat of the child's body sitting in the seat back 100 is sucked away by the first wind pressure structure 300 during the air circulation, thereby improving the child's riding comfort and achieving the purpose of reducing heat and dryness, thereby improving the comfort of the child safety seat.

[0047] Here, it should be noted that, in this embodiment, the first wind pressure structure 300 can be detachably provided on the chair back 100 , that is, the first wind pressure structure 300 can be installed on the chair back 100 as a separate component.

[0048] Of course, in other embodiments, the first wind pressure structure 300 and the seat back 100 may be integrally formed. Here, the integral formation of the first wind pressure structure 300 and the seat back 100 may be understood as the two being inseparable, and the first wind pressure structure 300 is not a separate component, or, it may be understood that a channel (i.e., the first wind gathering channel 302) is opened on the seat back structure of the child safety seat.

[0049] In order to enhance the comfort of the child safety seat, in the present embodiment, the child safety seat also includes a second fan 400, which is arranged on the seat back 100, and the second fan 400 is used to blow air into the seat back 100 or suck air into the seat back 100, so as to enhance the air flow in the seat back 100. At the same time, the child safety seat also includes a second wind pressure structure 500, which is arranged on the seat back 100, and the first wind pressure structure 300 is provided with a second wind gathering channel, wherein the second wind gathering channel is used to increase the wind pressure of the gas blown into the seat back 100 by the second fan 400 when the second fan 400 is in a blowing state, and the second wind gathering channel is used to make the gas in the seat back 100 be sucked into the second wind gathering channel when the second fan 400 is sucking air.

[0050] It is easy to understand that here, the principle of the second wind pressure structure 500 can refer to the principle of the above-mentioned first wind pressure structure 300, that is, the second wind pressure structure 500 can also realize the wind blown out by the second fan 400 through pressurization, so that the air volume and wind pressure are increased when discharged, and blown into the backrest 100. At the same time, the second fan 400 increases the speed of air circulation when sucking air, and inhales it through the second wind pressure structure 500 and discharges it out of the backrest 100 by the second fan 400. At this time, the body heat of the child sitting in the backrest 100 is sucked away by the second wind pressure structure 500 during the air circulation, thereby improving the riding comfort of the child and achieving the purpose of reducing heat and dryness, thereby improving the comfort of the child safety seat.

[0051] Here, it should be noted that, in this embodiment, the second wind pressure structure 500 can also be detachably provided on the chair back 100 , that is, the second wind pressure structure 500 can be installed on the chair back 100 as a separate component.

[0052] Of course, in other embodiments, the second wind pressure structure 500 and the seat back 100 may be integrally formed. Here, the second wind pressure structure 500 and the seat back 100 being integrally formed may be understood as the two being inseparable, and the second wind pressure structure 500 is not a separate component. Alternatively, it may be understood that a channel (i.e., a second wind gathering channel) is opened on the seat back structure of the child safety seat.

[0053] It should be noted that, in the present embodiment, the chair back 100 has a first side panel 110 and a second side panel 120 which are arranged relatively to each other, the first fan 200 and the first wind pressure structure 300 are both arranged on the first side panel 110, and the second fan 400 and the second wind pressure structure 500 are both arranged on the second side panel 120. Specifically, the first fan 200 and the second fan 400 can be respectively fixed to the first side panel 110 and the second side panel 120 by fasteners (such as screws, bolts, etc.).

[0054] Among them, Figure 3 As shown, the first fan 200 and the second fan 400 are located in the upper middle part of the entire chair back 100. The first fan 200 is arranged at this position so that it will not be blocked by the inner cushion in the chair back 100 used by the newborn nor by the headrest of the chair back 100.

[0055] At the same time, the airflows blown out by the first fan 200 and the second fan 400 will not blow directly to the vicinity of the child's waist, and will not affect the child's physical health.

[0056] In addition, the chair back 100 is provided with a first mounting groove 111 and a second mounting groove, both of which are located on the first side panel 110, the first mounting groove 111 is located on the inner side of the chair back 100, and the second mounting groove is located on the outer side of the chair back 100, the first wind pressure structure 300 is arranged in the first mounting groove 111, and the first fan 200 is arranged in the second mounting groove.

[0057] Of course, the chair back 100 is provided with a third mounting groove and a fourth mounting groove, both of which are located on the second side panel 120, the third mounting groove is located on the inner side of the chair back 100, and the fourth mounting groove is located on the outer side of the chair back 100, the second wind pressure structure 500 is arranged in the third mounting groove, and the second fan 400 is arranged in the fourth mounting groove.

[0058] In this embodiment, the structures of the first wind pressure structure 300 and the second wind pressure structure 500 are the same. Here, the structure of the first wind pressure structure 300 is used for explanation. Since the first wind focusing channel 302 needs to realize the functions of air intake and air outlet, the first wind focusing channel 302 has a first air outlet 301 and a second air outlet 303. It is easy to understand that when the first air outlet 301 is an air inlet, the second air outlet 303 can be an air outlet, or when the first air outlet 301 is an air outlet, the second air outlet 303 can be an air inlet, which is specifically determined according to whether the first fan 200 is in a blowing state or a sucking state.

[0059] Specifically, the second air outlet 303 is closer to the first fan 200 than the first air outlet 301. The first air outlet 301 is located on the inner wall of the chair back 100. When the first fan 200 blows air into the chair back 100, the first air outlet 301 is the air outlet and the second air outlet 303 can be the air inlet. When the first fan 200 sucks air into the chair back 100, the first air outlet 301 is the air inlet and the second air outlet 303 can be the air outlet.

[0060] In some embodiments, please refer to Figure 4 The area of ​​the first air outlet 301 is equal to the area of ​​the second air outlet 303. At the same time, the cross-sectional area of ​​the first wind focusing channel 302 is equal along the direction from the first air outlet 301 to the second air outlet 303. At this time, the first wind pressure structure 300 can be understood as a tubular wind pressure device.

[0061] In this embodiment, please refer to Figure 6 The area of ​​the first air outlet 301 is greater than the area of ​​the second air outlet 303. At the same time, the cross-sectional area of ​​the first wind focusing channel 302 gradually decreases from the first air outlet 301 to the second air outlet 303. At this time, the first wind pressure structure 300 can be understood as a funnel-type wind pressure device.

[0062] In some embodiments, please refer to Figure 5The area of ​​the first air outlet 301 may also be smaller than the area of ​​the second air outlet 303. At the same time, the cross-sectional area of ​​the first wind focusing channel 302 gradually increases along the direction from the first air outlet 301 to the second air outlet 303. At this time, the first wind pressure structure 300 can be understood as a wide-angle wind pressure device.

[0063] It is easy to understand that when the first fan 200 is blowing air, the larger the area of ​​the first air outlet 301 (i.e., the air outlet), the smaller the wind pressure blown out, the more divergent the airflow, and the shorter the distance of the blown airflow; the smaller the area of ​​the first air outlet 301, the greater the wind pressure at the first air outlet 301, and the farther the airflow blown out.

[0064] Alternatively, when the first fan 200 sucks air, the larger the area of ​​the first air outlet 301 (ie, the air suction outlet) is, the smaller the suction force is, and the smaller the area of ​​the first air outlet 301 is, the stronger the suction force can be.

[0065] In some embodiments, the first wind gathering channel 302 of the first wind pressure structure 300 may also be spiral-shaped. In this way, when the first fan 200 blows air, it not only increases the pressure, but also makes the wind rotate, so that the air is blown farther.

[0066] It should be noted that the spiral first air collection channel 302 may be a spiral air flow channel arranged inside the first air pressure structure 300, or may be a spiral air flow channel arranged inside the first air pressure structure 300. Figure 7 The first wind gathering channel 302 is a spiral groove arranged on the outer wall of the first wind pressure structure 300. The spiral groove and the peripheral wall of the first mounting groove 111 of the chair back 100 can jointly define an air flow channel.

[0067] It should be noted that, in this embodiment, please refer to Figure 2 In order to ensure the safety of children, a plurality of wind holes 310 are provided on the side of the first wind pressure structure 300 away from the first fan 200. The plurality of wind holes 310 are connected to the first wind collecting channel 302, and the plurality of air outlets are adjacent to the first air outlet 301. The airflow of the first wind collecting channel 302 enters the chair back 100 through the plurality of wind holes 310, or the gas in the chair back 100 is sucked into the first wind collecting channel 302 through the plurality of wind holes 310. This structure with a plurality of wind holes 310 can prevent children from directly contacting the first wind collecting channel 302 or even contacting the first fan 200, thereby ensuring the safety of children.

[0068] At the same time, the face cover of the chair back 100 is also fixedly arranged on the annular bottom side of the first wind pressure structure 300 away from the first fan 200 (the side close to the first fan 200) and the annular bottom side of the second wind pressure structure 500 away from the second fan 400 (the side close to the second fan 400). In this way, the face cover of the chair back 100 can be prevented from blocking the multiple air holes 310 of the first wind pressure structure 300 and the multiple air holes 310 of the second wind pressure structure 500.

[0069] In order to facilitate the control of the first fan 200 and the second fan 400, such as blowing or sucking air, the first fan 200 and the second fan 400 can be electrically connected or communicatively connected to a mobile device (such as a mobile phone), and the blowing or sucking of the first fan 200 and the second fan 400 can be controlled by the mobile device. Alternatively, the first fan 200 and the second fan 400 can be electrically connected or communicatively connected to the vehicle system, and the blowing or sucking of the first fan 200 and the second fan 400 can be controlled by the vehicle system. Of course, the chair back 100 itself can also have a controller, and the first fan 200 and the second fan 400 can be electrically connected or communicatively connected to the controller, and the blowing or sucking of the first fan 200 and the second fan 400 can be controlled by the controller.

[0070] For example Figure 8-Figure 10 As shown, for example, in this embodiment, by controlling the first fan 200 and the second fan 400 to blow or suck air, there can be three ventilation modes.

[0071] Please refer to Figure 8 In the first mode, both the first fan 200 and the second fan 400 blow air, which is equivalent to a two-way counter-blowing ventilation mode.

[0072] Please refer to Fig. 9 In the second mode, the first fan 200 blows air and the second fan 400 sucks air, which is equivalent to an in-and-out circulation ventilation mode.

[0073] Please refer to Fig.10 In the third mode, both the first fan 200 and the second fan 400 suck air, which is equivalent to a two-way suction ventilation mode.

[0074] In summary, the child safety seat includes a seat back 100, a first fan 200 and a first wind pressure structure 300, wherein the first fan 200 is arranged on the seat back 100, the first wind pressure structure 300 is arranged on the seat back 100, and the first wind pressure structure 300 is provided with a first wind collecting channel 302, wherein the first wind collecting channel 302 is used to increase the wind pressure of the gas blown into the seat back 100 by the first fan 200 when the first fan 200 is in a blowing state, and the first wind collecting channel 302 is used to make the gas in the seat back 100 be sucked into the first wind collecting channel 302 when the first fan 200 is sucking air.

[0075] Since wind pressure is generated by gathering the wind from the first fan 200, the first wind gathering channel 302 forms a wind gathering effect. After the wind blown out by the first fan 200 is pressurized by the first wind gathering channel 302, the wind volume and wind pressure are increased when it is discharged, and it is blown into the backrest 100, so as to improve the riding comfort of children and reduce heat and dryness. At the same time, when the first fan 200 sucks wind, the gas in the backrest 100 is sucked into the first wind gathering channel 302, increasing the speed of air circulation, and the air is sucked through the first wind pressure structure 300 and discharged out of the backrest 100 by the first fan 200. At this time, the heat of the child sitting in the backrest 100 is sucked away by the first wind pressure structure 300 during the air circulation, thereby improving the riding comfort of children and achieving the purpose of reducing heat and dryness, thereby improving the comfort of the child safety seat.

[0076] The child safety seat can greatly improve the comfort of children sitting in the child safety seat in hot summer and their ability to perceive the heat being taken away. In the blowing mode, the wind volume and wind pressure can be increased. In the suction mode, a large suction force can be generated to improve the air circulation in the child safety seat. The first wind pressure structure 300 and the second wind pressure structure 500 are not blocked by the accessories of the child safety seat itself, so that the wind of the first fan 200 will not be blocked. At the same time, the position of the first air outlet 301 of the first wind pressure structure 300 will not affect the physical health of the child.

[0077] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
