[0030] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0031] The present application provides a seat ventilation system, such as Figure 1-Figure 9 As shown, it includes a base 10, a fan 20, a mounting base 30, an air outlet housing 40 and a baffle 50. The base 10 is suitable for connecting with a seat, the mounting base 30 is suitable for installing the fan 20 to the base 10, the air outlet housing 40 is connected to the base 10, and the air outlet housing 40 includes an airflow channel 411. The baffle 50 is arranged on the air outlet side of the air outlet housing 40 relative to the airflow channel 411, so that the airflow driven by the fan 20 flows out to the peripheral side of the baffle 50 after passing through the airflow channel 411. By arranging the baffle 50 with a sheet structure on the air outlet side of the air outlet housing 40, it is avoided that the airflow passes through the airflow channel 411 and blows directly to the passengers, so that the airflow can change its flow direction and flow out from the peripheral side of the baffle 50 under the blocking of the baffle 50, and the air outlet area is relatively increased, and the passenger's body feeling can be improved, and the riding comfort can be improved. In particular, the seat ventilation system is suitable for use in child safety seats. In this case, the passengers are children with relatively fragile bodies. The ventilation system effectively prevents children from feeling uncomfortable or even getting sick due to direct blowing of cold air. It is more child-friendly while having a cooling effect.

[0032] In some embodiments, the air outlet housing 40 includes an air outlet channel 421 arranged around the air flow channel 411 so that the airflow driven by the fan 20 passes through the air flow channel 411 and the air outlet channel 421 in sequence and then flows out from around the baffle 50 . Figure 1 The thick arrow in the figure indicates the air outlet direction. The setting of the air outlet channel 421 can collect the airflow and guide the flow direction of the airflow.

[0033] In some embodiments, the seat ventilation system also includes a heating module and / or a cooling module. The heating module / cooling module is arranged on the flow path of the airflow, for example, in the airflow channel 411 or the air outlet channel 421, and is used to adjust the temperature of the airflow to achieve multiple modes of cold air, hot air, and natural wind, which can adapt to various needs in different seasons and different occasions.

[0034] In some embodiments, fans 20 are respectively disposed on two opposite sides of the base 10, and the fans 20 on each side have corresponding air outlet housings 40 and baffles 50 to form two relatively independent ventilation modules, so that air can be discharged from both sides of the seat at the same time, so as to form a better air flow effect.

[0035] The fan 20 may be a centrifugal fan, an axial flow fan, a mixed flow fan, etc. The fan 20 may be operated by an external power supply or a built-in power supply. The fans 20 on both sides may be controlled uniformly or independently, and the fan 20 may control the wind speed and wind volume to meet different usage requirements.

[0036] In some embodiments, the base 10 includes a main body 11 and two side parts 12, and a side part 12 is provided at each end of the main body 11. The main body 11 is suitable for connecting with the backrest or seat cushion of the seat, and the two side parts 12 extend forward relative to the main body 11 and are suitable for installing the fan 20. In other words, when viewed from above, the projection of the base 10 is U-shaped, and the fan 20 can be installed on the left and right sides of the seat respectively. It is easy to understand that when the seat ventilation system is applied, the mounting base 30, the fan 20, the air outlet housing 40 and the baffle 50 can be assembled on both sides of the base 10 based on the base 10, and then the base 10 can be assembled to the relevant part of the seat, and the entire ventilation system can be easily disassembled and assembled as a whole.

[0037] In a specific embodiment, the main body 11 is a sheet-like structure extending along the curved surface. The main body 11 extends along the left-right direction of the seat and extends from the left side of the seat to the right side of the seat. The main body 11 is suitable for connecting with the backrest or seat cushion of the seat, that is, the main body 11 is suitable for fitting with the backrest or seat cushion of the seat, or the main body 11 is suitable for constituting a partial structure of the backrest / seat cushion. The side portion 12 extends along the front-to-back direction of the seat, so that when a passenger sits down, the main body 11 is located behind or below the passenger, and the two side portions 12 are located on the left and right sides of the passenger.

[0038] In some embodiments, the mounting seat 30 includes a fixing frame 31 and a connecting piece 32, the fixing frame 31 is adapted to surround at least part of the circumference of the fan 20, the fixing frame 31 is connected to the base 10, and the two cooperate to fix the fan 20, and the connecting piece 32 is connected to the fixing frame 31 and extends toward the inner side of the seat to connect with the base 10. The fixing frame 31 and the connecting piece 32 are both connected to the base 10, and the multi-point connection is more stable and reliable, and the connecting piece 32 can cooperate with the base 10 to guide the airflow blown out by the fan 20 into the airflow channel 411.

[0039] In a specific embodiment, the fixing frame 31 is U-shaped, and includes a first frame 311, a second frame 312, and a third frame 313 arranged in sequence.

The fixing frame 31 cooperates with the side portion 12 to fix the fan 20 having a basic quadrilateral shape. When installing the fan 20, first insert the fan 20 from the U-shaped opening end of the fixing frame 31, so that the bottom of the fan 20 abuts against the second frame 312, and then connect the first frame 311, the third frame 313 and the connecting piece 32 to the base 10 respectively. The connection structure is simple and easy to assemble.

[0040] Furthermore, the four corners of the fan 20 are provided with insertion parts 21, and corresponding slots 1211 are respectively provided between the first frame 311 and the second frame 312, between the second frame 312 and the third frame 313, and on the first mounting ear 121 and the second mounting ear 122.

The connection structure is simple and reliable, and the processing and use cost is low.

[0041] In some embodiments, the base 10 and the mounting base 30 are detachably connected to facilitate replacement and maintenance of the fan 20. Specifically, the fixing frame 31 and the connecting piece 32 are both detachably connected to the base 10, which can be one or more of a snap connection, a fixing member connection such as a bolt connection, and a plug connection.

[0042] In some embodiments, the front and rear sides of the connecting piece 32 are both provided with structures suitable for connecting with the base 10 to increase the connection strength. Specifically, one side of the connecting piece 32 is provided with a slot 321 suitable for connecting with a buckle, and the other side is provided with a plug-in slot 322 suitable for plugging with the base 10.
