[0026] In order to keep the following description of the embodiments of the present application clear and concise, detailed descriptions of known functions and known components are omitted.

[0027] As shown in Figure 1 and Figure 2 An installation mechanism of a seat ventilation device according to an embodiment of the present application is disclosed, which comprises: a wind bag mechanism, a leaf spring, and a fan.

[0028] The wind bag mechanism can be a wind bag in the prior art. Specifically, the wind bag comprises a bag body and a supporting component arranged in the bag body for supporting the front bag part and the rear bag part of the bag body apart. If the wind bag mechanism is a wind bag in the prior art, the front bag part is provided with an air hole, which is in communication with the ventilation hole of the seat body. The front bag part is configured as a flexible or semi-flexible sheet body and is provided with a first interface in communication with the fan.

[0029] The utility model provides a kind of wind bag mechanism different from the wind bag in prior art, which comprises a flexible or semi-flexible sheet body, a plurality of grooves are pre-configured on the back side of the seat body, the ventilation hole of the seat body penetrates to the groove bottom of the groove, the sheet body covers the back side of the seat body to define a plurality of air ducts with the groove, a first interface is configured on the sheet body, the fan is communicated with the first interface by making the interface (not called the second interface) of the fan, so that the fan is communicated with the air duct, in this way, the fan can provide airflow to the air duct, and the airflow in the air duct blows to the front side of the seat body through the ventilation hole to ventilate for the occupant. The space occupied by the wind bag mechanism of this structure is significantly smaller than that of the wind bag in the prior art.

[0030] The plate spring is located on the back side of the sheet body, and the main function of the plate spring is to provide support for the seat body. In the utility model, a positioning groove is configured at the position corresponding to the first interface of the sheet body, and a docking portion is configured on the shell of the fan. The docking portion matches the positioning groove, that is, after the docking portion passes through the positioning groove, the positioning groove limits the radial movement of the docking portion. The inside of the docking portion defines a second interface, and the airflow provided by the fan blows out from the second interface. When installing the fan, the docking portion passes through the positioning groove, and the second interface is docked with the first interface, so that the fan can provide airflow to the air duct. Preferably, a positioning frame protruding in the thickness direction is formed on the plate spring, and the positioning groove is defined in the positioning frame. This makes the positioning groove have a certain axial size, so that after the docking portion passes through the positioning groove, the positioning groove can stably position the docking portion to avoid excessive installation error of the fan relative to the plate spring. A plurality of threaded holes are arranged on the plate spring around the positioning groove, a plurality of through holes corresponding to the studs are machined on the shell of the fan, and a bolt is arranged in each through hole. The bolt is screwed into the threaded hole of the stud at the same time to fix the fan.

[0031] The utility model makes the interface of the fan and the interface of the sheet body in fluid communication while mechanically fixing the fan with the plate spring, thereby realizing stable assembly of the fan and avoiding shaking of the fan.

[0032] Preferably, the first interface and the shape of the docking portion match, so that the docking portion is inserted into the first interface. Preferably, the positioning groove is a rectangular groove, and the docking portion is a tetrahedral column matching the rectangular groove.

[0033] In some preferred embodiments, a sealing gasket is arranged between the sheet body and the plate spring to prevent leakage of the airflow provided by the fan.
