Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0038] To improve children's riding comfort, child seats are typically equipped with ventilation systems for heat dissipation. These systems usually include both suction and blowing modes; suction mode provides a relatively gentle airflow, while blowing mode generates a stronger airflow, which can easily cause children to catch a cold. This application proposes a child seat 100, which can be used in vehicles such as cars, trains, ships, and airplanes, and features excellent ventilation and heat dissipation, thereby improving children's riding comfort and promoting their physical and mental health.

[0039] Please refer to Figures 1 to 3 This embodiment provides a child seat 100, including a seat body 110, a fan 150, and a ventilation pad 140. The seat body 110 includes a seat front 101 and a seat back 103 disposed opposite to each other. The ventilation pad 140 is disposed on the seat front 101, and the fan 150 is mounted on the seat body 110. A siphon air duct 111 is formed between the seat front 101 and the ventilation pad 140. An air inlet 121 is provided on the seat body 110, and an air outlet 165 is provided on the seat back 103. The air inlet 121 is connected to the siphon air duct 111, and the siphon air duct 111 is connected to the fan 150. The fan 150 is used to exhaust the airflow passing through the siphon air duct 111 from the air outlet 165. The fan 150 adopts a suction mode, so that a large amount of air enters the siphon air duct 111, increasing the airflow and realizing the ventilation and heat dissipation function of the child seat 100, which greatly improves the comfort of the child seat 100.

[0040] Please refer to Figure 4 and Figure 5 Furthermore, the ventilation pad 140 has multiple first ventilation holes 141, which are connected to the siphon duct 111. When the fan 150 is in suction mode, air not only enters the siphon duct 111 in large quantities from the air inlet 121, but also from the first ventilation holes 141, increasing the air intake, expanding the ventilation area, and enhancing the ventilation and heat dissipation effect. It can be understood that the seat body 110 includes an interconnected seat portion 120 and a backrest 130. The seat portion 120 supports the user's buttocks, and the backrest 130 supports the user's waist and back. In this embodiment, the ventilation pad 140 is laid on the front 101 of the seat, partially or completely covering the seat portion 120 and the backrest 130. The first ventilation holes 141 are arranged at intervals on the ventilation pad 140, that is, the ventilation pad 140 corresponding to the seat portion 120 and the backrest 130 is provided with the first ventilation holes 141. In this way, airflow passes through both the seat portion 120 and the backrest 130, the ventilation area is large and the ventilation effect is good. After the fan 150 is turned on, the heat dissipation efficiency can be greatly improved.

[0041] Optionally, the shape of the first ventilation hole 141 can be circular, square, triangular, elliptical, or any other arbitrary shape. The first ventilation holes 141 on the ventilation pad 140 can be arranged in a rectangular array or a circular array; they can be regularly and uniformly distributed or randomly arranged, without specific limitations. In this embodiment, in order to achieve a better siphon effect and facilitate production, the first ventilation hole 141 on the ventilation pad 140 is a circular hole with a diameter less than or equal to 3mm, such as 1mm, 1.5mm, 2mm, or 2.5mm. The diameter of all the first ventilation holes 141 can be equal or unequal, without specific limitations.

[0042] The ventilation cushion 140 has multiple protrusions 143 spaced apart. The ends of the protrusions 143 furthest from the ventilation cushion 140 are positioned on the seat front 101, creating a siphon airflow duct 111 between the seat front 101 and the ventilation cushion 140. The protrusions 143 support the ventilation cushion 140, forming the siphon airflow duct 111 between the ventilation cushion 140 and the seat front 101. The height of the protrusions 143 on the ventilation cushion 140 is the height of the siphon airflow duct 111. The protrusions 143 can be solid or hollow. They can be arranged in a rectangular array or a circular array on the ventilation cushion 140; they can be evenly distributed regularly or randomly arranged; the shape of the protrusions 143 can be cylindrical, prismatic, frustum-shaped, spherical, ellipsoidal, or any other arbitrary shape, without specific limitations. In this embodiment, the areas on the ventilation pad 140 corresponding to the user's buttocks and back experience relatively greater stress, so the number of protrusions 143 at these locations can be increased, resulting in a higher density of protrusions 143. Conversely, at the remaining edge areas, where the stress on the ventilation pad 140 is relatively less, the number of protrusions 143 can be reduced, resulting in a lower density of protrusions 143. However, this is not a limitation; the number and density of protrusions 143 can be flexibly adjusted according to actual conditions, and no specific limitation is made here. The protrusions 143 also evenly disperse the airflow within the siphon duct 111, making ventilation and heat dissipation more uniform.

[0043] To improve the siphon effect of the siphon duct 111, the edge of the ventilation pad 140 is sealed to the seat body 110. This means the edge of the ventilation pad 140 directly contacts the seat front 101, utilizing the material properties of both to achieve a close fit and seal. Alternatively, a separate seal can be provided at the edge of the ventilation pad 140 to create a sealed connection between the edge of the ventilation pad 140 and the seat front 101, preventing airflow turbulence. The seal may include, but is not limited to, sealing rings, adhesives, or other sealing connectors. By sealing the edge of the ventilation pad 140 to the seat body 110, the siphon duct 111 can better concentrate airflow and prevent air leakage at the edges. When the fan 150 is turned on, most of the air enters the siphon duct 111 from the air inlet 121, and the remaining air enters the siphon duct 111 from the first ventilation hole 141 on the ventilation pad 140, increasing the ventilation area and increasing the airflow volume of the siphon duct 111, resulting in stronger air concentration. The airflow direction within the siphon duct 111 is consistent, and all airflow passes through the fan 150 and is discharged from the air outlet 165, resulting in better ventilation and heat dissipation. It should be noted that, in order to improve the riding comfort of the child seat 100, some covering fabric is also provided on the front of the seat 101 to cover the ventilation pad 140, meaning that the ventilation pad 140 does not directly contact the user.

[0044] Please refer to Figure 6 Optionally, the air inlet 121 can be located on the front or back of the seat body 110, as long as it is connected to the siphon duct 111. In this embodiment, the air inlet 121 is located on the front of the seat body 110, and at the edge of the ventilation pad 140 near the seat portion 120. With this arrangement, airflow enters the siphon duct 111 from the air inlet 121, providing ventilation and heat dissipation for the user's buttocks, waist, and back, making full use of the siphon duct 111, increasing the ventilation area, improving heat dissipation efficiency, and enhancing the user's experience. Of course, this is not the only option; the air inlet 121 can also be located on the back of the seat 103 or other locations on the seat body 110, which is not specifically limited here.

[0045] Please refer to Figure 7 and Figure 8The seat front 101 is provided with a mounting cover 151, and the fan 150 is fixed to the mounting cover 151. Optionally, the fan 150 can be fixed to the mounting cover 151 with screws, and the mounting cover 151 can be fixed to the seat body 110 with screws. Of course, the connection method and components between the fan 150 and the mounting cover 151, the fan 150 and the seat body 110, or the mounting cover 151 and the seat body 110 are not limited to screw connection. Other fixing methods such as snap connection, threaded connection, adhesive bonding, or riveting can also be used, and no specific limitation is made here. Further, the mounting cover 151 has an air concentrator 153, which is connected to the siphon air duct 111, and the air concentrator 153 is correspondingly arranged with the fan 150. The airflow after passing through the siphon air duct 111 enters the air concentrator 153 of the mounting cover 151, and is then discharged from the air outlet 165 of the seat back 103 by the fan 150. The design of the air concentrator 153 can increase airflow, enhance the air gathering effect, and further improve ventilation and heat dissipation performance.

[0046] Furthermore, in this embodiment, the air concentrator 153 is funnel-shaped, and the opening of the air concentrator 153 gradually increases from the side of the mounting cover 151 closest to the siphon duct 111 to the side furthest from the siphon duct 111. The smaller the opening of the air concentrator 153 at the end closest to the siphon duct 111, the stronger the air concentrator's ability and the better the air concentrator's effect. The larger the opening of the air concentrator 153 at the end furthest from the siphon duct 111, the greater the exhaust capacity and the larger the exhaust volume, which can accelerate airflow and improve ventilation and heat dissipation.

[0047] In this embodiment, there are two fans 150 arranged side by side, which increases the ventilation area and ventilation force, resulting in higher ventilation and heat dissipation efficiency and better heat dissipation effect. In other optional embodiments, the number of fans 150 can be one, three, four or more, and no specific limitation is made here.

[0048] Please refer to Figure 9The seat body 110 is also equipped with an electronic module 161, which is connected to the fan 150 and used to control the start and stop of the fan 150. Optionally, the electronic module 161 is equipped with a temperature sensor, which is used to detect the temperature of the seat body 110. The electronic module 161 controls the start and stop of the fan 150 based on the temperature of the seat body 110. For example, when the temperature sensor detects that the temperature of the seat body 110 is higher than a preset temperature, the electronic module 161 controls the fan 150 to turn on automatically, ventilating the seat body 110 and achieving automatic heat dissipation and cooling. When the temperature sensor detects that the temperature of the seat body 110 is less than or equal to the preset temperature, the electronic module 161 controls the fan 150 to turn off automatically, and the seat body 110 shuts off its air intake mode to prevent the user from getting cold due to excessively low temperatures. The electronic module 161 can be a controller, such as a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. Of course, the controller can also be integrated into a PLC controller, a microcontroller, etc., without specific limitations here.

[0049] Of course, it is not limited to this. A physical switch can be installed on the seat body 110 to manually control the start and stop of the fan 150, or to control the start and stop of the fan 150 through a mobile APP or other means.

[0050] The seat backrest 103 is provided with a protective shell 163, and the protective shell 163 is provided with an air outlet 165, which is correspondingly arranged with the fan 150. In this embodiment, since there are two fans 150, there are also two corresponding air outlets 165. The protective shell 163 is used to protect the fans 150 and the electronic module 161. Optionally, the seat backrest 103 is also provided with a rear cover 170, which is located on the side of the protective shell 163 away from the fans 150, and the rear cover 170 is provided with a second ventilation hole 171. There are multiple second ventilation holes 171, which are spaced apart on the rear cover 170. The rear cover 170 protects the fans 150, electronic module 161, and protective shell 163 and other components provided on the seat body 110. The second ventilation holes 171 on the rear cover 170 can perform a ventilation function, so that the airflow from the air outlet 165 is dispersed through the second ventilation holes 171. It is easy to understand that the arrangement of the second ventilation hole 171 on the rear cover 170 is similar to the arrangement of the first ventilation hole 141 on the ventilation pad 140, and will not be described again here. In addition, the protective shell 163 and the rear cover 170 can be fixed to the back of the seat 103 by screws, adhesive, snap-fit ​​or other means, and no specific limitation is made here.

[0051] This invention also provides a vehicle, including a vehicle body and a child seat 100 as described in any of the foregoing embodiments, wherein the child seat 100 is mounted on the vehicle body. The child seat 100 not only ensures the safety of children during vehicle travel but also provides ventilation and heat dissipation, improving the comfort of children while riding.

[0052] The working principle of the child seat 100 and the vehicle provided in this embodiment of the invention is as follows:

[0053] A ventilation pad 140 is provided on the front of the seat body 110, forming a siphon air duct 111 between the ventilation pad 140 and the seat front 101. The ventilation pad 140 has a first ventilation hole 141. When the fan 150 turns on the suction mode, most of the air enters the siphon air duct 111 from the air inlet 121 on the seat body 110, and the other part of the air enters the siphon air duct 111 from the first ventilation hole 141 on the ventilation pad 140. Under the action of the fan 150, the airflow entering the siphon air duct 111 passes through the air concentrator 153 and the fan 150, and is discharged from the air outlet 165 on the seat back 103. During the airflow process, the seat part 120 and the backrest 130 on the seat body 110 are ventilated and cooled. The setting of the siphon air duct 111 and the first ventilation hole 141 increases the ventilation area, the airflow is more uniform and gentle, the ventilation and cooling effect is good, and the heat dissipation efficiency is high.

[0054] When a child sits in the child seat 100, the temperature sensor in the electronic module 161 detects that the temperature inside or around the seat body 110 exceeds the preset temperature. The electronic module 161 then controls the fan 150 to automatically start, and the child seat 100 automatically activates its ventilation and cooling function. This is flexible, convenient, and highly automated. Alternatively, the fan 150 can also be controlled via a mobile app or a physical switch on the seat body 110 to keep the child cool and comfortable.

[0055] In summary, the child seat 100 and vehicle provided by the embodiments of the present invention have the following beneficial effects:

[0056] The child seat 100 provided in this embodiment of the invention adopts a suction mode. By setting up a siphon air duct 111, the ventilation area is larger, the airflow is more uniform and gentle, and the heat dissipation efficiency is high. While ensuring the safety of children riding in vehicles, it also has ventilation and heat dissipation functions, improving the user's riding comfort. This child seat 100 has a simple structure, flexible operation, is easy to use, and has good ventilation and heat dissipation effects, making it highly valuable for widespread application.

[0057] The vehicle provided in this embodiment of the invention includes the aforementioned child seat 100, which not only ensures the safety of children riding in the vehicle, but also automatically realizes ventilation and heat dissipation functions, with a larger ventilation area and more uniform and gentle airflow, greatly improving the comfort of children riding in the vehicle.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
