DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The purpose of the utility model is to provide a car seat ventilation system and a car seat to solve the problems existing in the above-mentioned prior art. The ventilation pipe and the air inlet of the ventilation bag are fixedly connected to avoid the risk of the interface falling off when the car is bumpy.

[0037] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] The utility model provides a vehicle seat ventilation system, referring to Figure 1 to Figure 14 As shown, it includes a fan 1 fixedly arranged on the seat cushion bottom spring 4 of the automobile seat, and the fan 1 is fixed on the seat cushion bottom spring 4 by a fixing glue nail 8. The fixing glue nail 8 is made of silica gel, which is soft and has a good buffering effect. The fan 1 is connected to the power supply in the car and can generate the required wind; a ventilation bag 3 is laid on the automobile seat, and a plurality of air outlets 17 are provided on the side close to the skin. The air outlet holes 17 are located on the side close to the human body and are used to evenly blow out the wind generated by the fan 1 to achieve a ventilation effect; in order to realize the transmission of wind between the fan 1 and the ventilation bag 3, the utility model is also provided with a ventilation pipe 2, one end of which is connected to the air outlet of the fan 1, and the other end is fixedly connected to the air inlet 16 of the ventilation bag 3, which is used to transport the wind generated by the fan 1 into the ventilation bag 3 and blow it out through the air outlet holes 17; the ventilation pipe 2 is formed by blow molding of TPV rubber with a relatively high hardness (80-85 hardness), has a certain strength, can support the air duct, and has a certain flexibility, which is convenient for installation.

[0039] The traditional ventilation duct 2 and the ventilation bag 3 are connected by snapping, but they are easy to fall off when the car is bumpy. The utility model is different. An extension part is provided at one end of the ventilation duct 2 of the utility model, and the extension part is a sheet structure. It is sewn to the air inlet of the ventilation bag 3, so that the connection is more firm and will not fall off. In order to facilitate connection and sewing, in an optimal embodiment, a positioning hole 10 is opened on the extension part for positioning when sewing with the air inlet 16 of the ventilation bag 3; in addition to the above-mentioned sewing connection method, the utility model can also adopt other forms such as fixed adhesive connection and binding connection, as long as it is ensured that the connection position is stable and will not fall off and will not affect the air intake.

[0040] The ventilation duct 2 has a smooth 90-degree bend transition structure in the middle, and its side wall near the extended portion has a corrugated structure 11. The overall structure here is similar to a bellows, which can shrink up and down to provide a certain amount of activity. When the car seat is bumped or impacted, the ventilation duct 2 can provide a certain degree of deformation to prevent the ventilation duct 2 from falling off.

[0041] In order to facilitate the connection between the fan 1 and the ventilation duct 2, the utility model has a hanging ear 9 fixedly provided at the end of the ventilation duct 2 away from the ventilation bag 3. The hanging ear 9 extends outward and has a snap-on structure at the end. When the end of the ventilation duct 2 provided with the hanging ear 9 is mounted on the air outlet of the fan 1, the hanging ear 9 can be snap-connected with the fan 1. A card slot is provided on the side wall of the end of the ventilation duct 2 away from the ventilation bag 3. The card slot includes an inner card slot 12 and an outer card slot 13 which are integrally formed with the ventilation duct 2 and arranged in sequence. When the end of the ventilation duct 2 provided with the hanging ear is mounted on the air outlet of the fan 1, the inner card slot 12 can cooperate with the flange 15 of the air outlet of the fan 1 to prevent it from falling off; the outer card slot 13 is used to mount a retaining spring 14 on the outside. The outer card slot 13 cooperates with the retaining spring 14 to fix the air outlet more firmly. When the retaining spring 14 is used, such as Fig.11 As shown, the directions of the two symmetrical arrows in the figure are the directions of applied force. Press the ears at both ends of the retaining spring 14, the retaining spring 14 will deform and the opening will become larger. After inserting it into the outer slot 13 of the ventilation pipe 2, let go, the retaining spring 14 will return to its original shape, the opening will become smaller, and the ventilation pipe 2 will be clamped to prevent it from falling off.

[0042] In order to achieve a better ventilation effect, the ventilation bag 3 of the utility model includes two layers of symmetrically arranged and welded PU films 18, and a layer of 3D fabric 19 is provided between the two layers of PU films 18. The 3D fabric 19 plays a role in supporting the air duct. A layer of non-woven fabric 20 is glued to the PU film 18 on the side close to the air inlet of the ventilation bag 3. The non-woven fabric 20 has a certain strength, and the ventilation pipe 2 can be sewn on it, and it can also prevent the soft PU film 18 from being crushed by the seat cushion bottom spring 4 to leak air.

[0043] In a different embodiment, the utility model further provides a car seat, including a seat frame 5, a seat cushion bottom spring 4 is provided on the seat frame 5, and the above car seat ventilation system is provided on the seat cushion bottom spring 4; a foaming layer 6 and a soft layer 7 are provided in sequence on the side of the seat frame 5 away from the seat cushion bottom spring 4, thereby realizing the overall structural arrangement of the car seat. On this basis, a car can also be provided, in which the above car seat is installed, thereby realizing the seat ventilation effect in the car.
