DETAILED DESCRIPTION

[0027] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] The terms "comprises" 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 that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0031] The present application provides a seat ventilation system, as shown in Figures 1 to 9 , comprising a base 10, a fan 20, a mounting base 30, an air outlet housing 40, and a baffle 50. The base 10 is adapted to be connected to a seat, the mounting base 30 is adapted to mount the fan 20 to the base 10, and the air outlet housing 40 is connected to the base 10. The air outlet housing 40 includes an air flow channel 411. The baffle 50 is disposed on the outlet side of the air outlet housing 40 relative to the air flow channel 411, so that the airflow driven by the fan 20 flows through the air flow channel 411 and then flows outward toward the periphery of the baffle 50. By disposing the sheet-like baffle 50 on the outlet side of the air outlet housing 40, the airflow is prevented from directly blowing toward the passenger through the air flow channel 411. Instead, the airflow is diverted by the baffle 50 and flows outward toward the periphery of the baffle 50, thereby increasing the air outlet area and improving passenger comfort. 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 avoids the discomfort or even illness of children caused by direct blowing of cold air. It has a cooling effect and is more friendly to children.

[0032] In some embodiments, the air outlet housing 40 includes an air outlet channel 421 disposed around the air flow channel 411, so that the airflow driven by the fan 20 sequentially passes through the air flow channel 411 and the air outlet channel 421 before flowing out from around the baffle 50. The thick arrows in FIG1 indicate the direction of air flow. The provision of the air outlet channel 421 can collect and guide 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 air flow path, for example, in the air flow channel 411 or the air outlet channel 421, and is used to adjust the temperature of the air flow 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 provided on opposite sides of the base 10. Each fan 20 has a corresponding air outlet housing 40 and baffle 50, forming two relatively independent ventilation modules. This allows air to be simultaneously discharged from both sides of the seat, thereby achieving a better air flow effect.

[0035] The fan 20 may be a centrifugal fan, an axial flow fan, a mixed flow fan, or the like. The fan 20 may be powered by an external power source or a built-in power source. The fans 20 on both sides may be controlled collectively or independently, and the wind speed and air volume of the fans 20 may be controlled to suit different usage requirements.

[0036] In some embodiments, the base 10 includes a main body 11 and two side portions 12, with a side portion 12 disposed at each end of the main body 11. The main body 11 is adapted to connect to the backrest or seat cushion of a seat, and the two side portions 12 extend forward relative to the main body 11 and are adapted to mount a fan 20. In other words, when viewed from above, the projection of the base 10 is U-shaped, enabling fans 20 to be mounted on the left and right sides of the seat. It is readily understood that when applying this seat ventilation system, the mounting base 30, fan 20, air outlet housing 40, and 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 portion of the seat. The entire ventilation system can then be easily assembled and disassembled as a whole.

[0037] In one embodiment, the main body 11 is a sheet-like structure extending along a curved surface. The main body 11 extends in the left-right direction of the seat, from the left side to the right side. The main body 11 is adapted to connect with the seat back or cushion, that is, it is adapted to conform to the seat back or cushion, or it is adapted to form a partial structure of the backrest / cushion. The side portions 12 extend in the fore-aft direction of the seat, such that when a passenger is seated, the main body 11 is positioned behind or below the passenger, with the two side portions 12 positioned to the left and right of the passenger.

[0038] In some embodiments, the mounting base 30 includes a fixing frame 31 and a connecting piece 32. The fixing frame 31 is adapted to surround at least a portion 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. The connecting piece 32 is connected to the fixing frame 31 and extends toward the inside of the seat to connect to 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. The connecting piece 32 can cooperate with the base 10 to guide the airflow blown by the fan 20 into the airflow channel 411.

[0039] In one embodiment, the fixing frame 31 is U-shaped and includes a first frame 311, a second frame 312, and a third frame 313, which are sequentially arranged. Correspondingly, a first mounting ear 121 and a second mounting ear 122 are provided on the side portion 12 of the base 10. The first frame 311 is connected to the first mounting ear 121, and the third frame 313 is connected to the second mounting ear 122. The fixing frame 31 cooperates with the side portion 12 to secure the fan 20, which has a basic quadrilateral shape. When installing the fan 20, the fan 20 is first inserted from the U-shaped opening of the fixing frame 31, so that the bottom of the fan 20 abuts against the second frame 312. The first frame 311, the third frame 313, and the connecting piece 32 are then connected to the base 10. The connection structure is simple and easy to assemble.

[0040] Furthermore, insertion portions 21 are provided at the four corners of the fan 20. Corresponding slots 1211 are provided between the first and second frames 311 and 312, between the second and third frames 312 and 313, and on the first and second mounting ears 121 and 122, respectively. Insertion portions 21 are inserted into slots 1211 to prevent the fan 20 from being separated from the seat frame 31 in the left or right direction. This connection structure is simple and reliable, with low manufacturing and use costs.

[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, and can be specifically connected by one or more of a snap connection, a fixing member connection such as a bolt connection, a plug connection, and the like.

[0042] In some embodiments, both the front and rear sides of the connecting piece 32 are provided with structures suitable for connecting to 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 into the base 10. This connection structure is simple, easy to assemble, and has low processing and use costs.

[0043] In some embodiments, the air outlet housing 40 includes a connecting portion 41 and a guide portion 42. The connecting portion 41 is connected to the base 10. An air flow channel 411 is formed inside the connecting portion 41. The mounting base 30 and the base 10 cooperate to guide the airflow driven by the fan 20 into the air flow channel 411. The guide portion 42 is connected to the connecting portion 41 and extends in all directions relative to the connecting portion 41 to form an air outlet channel 421 on the side of the air flow channel 411 that is suitable for guiding the direction of airflow outflow. In other words, the area opposite the guide portion 42 and the baffle 50 is recessed to form an air outlet channel to guide the direction of airflow. Furthermore, the top of the guide portion 42 is expanded outward and is provided with reinforcing ribs 422 to increase the structural strength of the air outlet housing.

[0044] In some embodiments, the air outlet housing 40 is detachably connected to the base 10. In one specific embodiment, the air outlet housing 40 is provided with a lock latch 412, and the base 10 is provided with a lock slot 123. The lock latch 412 and the lock slot 123 are snap-fitted together to lock the air outlet housing 40 to the base 10. This connection structure is simple, easy to assemble, and has low processing and use costs. Furthermore, the lock latch 412 and the lock slot 123 are provided in multiple pairs, and the multi-point connection increases the connection strength.

[0045] In some embodiments, the baffle 50 includes a plate body 51 and a connecting protrusion 52. The connecting protrusion 52 is arranged on the side of the plate body 51 facing the air flow channel 411, and extends toward the air outlet housing 40 to be connected to the air outlet housing 40. The plate body 51 is blocked above the air flow channel 411, and the plate body 51 is spaced apart from the air flow channel 411.

[0046] In some embodiments, the base 10, the mounting base 30, the air outlet shell 40, and the baffle 50 are respectively an integrated structure. Compared with the split structure, the integrated structure is more stable and reliable, and all major components are an integrated structure. When assembling the seat ventilation system, there are fewer assembly steps, which is convenient for assembly.

[0047] In some embodiments, any two of the five components, including the base 10 , the fan 20 , the mounting base 30 , the air outlet housing 40 , and the baffle 50 , are detachably connected to facilitate maintenance and replacement of the components.

[0048] The present application also provides a child safety seat that utilizes any of the above-mentioned seat ventilation systems. Compared to a method in which airflow is directly discharged to the outside along the axial direction of the airflow channel 411 and blows toward the child, the airflow area is enlarged, the airflow is prevented from directly blowing toward the child, the child feels better, and the probability of the child getting sick is reduced.

[0049] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application.
