Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a suction fan fixing mechanism for an automobile seat backrest. Background Art

[0002] With the continuous advancement of technology, the functions of car seats are becoming more and more perfect. At present, most car seat backs are equipped with blowing or sucking fan structures for ventilation. However, most of the blowing or sucking fans on the current market are installed on the foam back of the seat back, and the blowing or sucking fans need to be installed through a separate fixing structure. When the seat space is small, there is a problem that the ventilation fan cannot be arranged. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a vehicle seat back suction fan fixing mechanism for installing the suction fan inside the seat foam to overcome the above-mentioned deficiencies of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A vehicle seat back suction fan fixing mechanism comprises: a seat back, a seat frame located inside the seat back, and a seat foam arranged on the seat frame, wherein the improvement made is that a ventilation soft foam for ventilation is arranged at the front end of the seat foam, an inlay groove for installing the suction fan, and a ventilation duct connecting the inlay groove and the ventilation soft foam are arranged inside the seat foam, a hot-pressed felt for sealing the suction fan and the seat foam is adhered to the rear end of the seat foam, a plurality of ventilation holes for communicating with the seat surface are arranged on the ventilation soft foam, air inlet holes corresponding to the ventilation holes are opened on the seat foam, the suction fan is installed in the inlay groove, the air suction port of the suction fan is connected with the ventilation duct, and the suction fan transports hot air from the seat surface to the back of the seat through the ventilation duct.

[0006] As a preferred embodiment of the present invention, the shape of the hot-pressed felt is the same as the shape of the ventilation duct.

[0007] The advantages and positive effects of the utility model are:

[0008] 1. The seat back suction fan fixing mechanism of the utility model does not need to use brackets, rubber nails and other parts to fix the seat ventilation fan;

[0009] 2. The utility model has the advantages of simple structure, low failure rate and saving seat space. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] See also Figure 1-3 The present embodiment provides a vehicle seat back suction fan fixing mechanism, comprising: a seat back, a seat frame located inside the seat back, and a seat foam 1 arranged on the seat frame, a ventilation soft foam 2 for ventilation is arranged at the front end (front) of the seat foam 1, an inlay groove 4 for installing an air suction fan 3 and a ventilation duct 5 connecting the inlay groove 4 and the ventilation soft foam 2 are arranged inside the seat foam 1, a hot-pressed felt 6 for sealing the air suction fan 3 and the seat foam 1 is pasted on the rear end (back) of the seat foam 1, a plurality of ventilation holes 7 for communicating with the seat surface are arranged on the ventilation soft foam 2, an air inlet hole corresponding to the ventilation hole 7 is opened on the seat foam, and the position of the air inlet hole corresponds to the position of the ventilation duct 5, the air suction fan 3 is installed in the inlay groove 4, and the air suction port of the air suction fan 3 is connected with the ventilation duct 5, and the air suction fan 3 transports the hot air on the seat surface to the back of the seat through the ventilation duct 5, that is, the hot air on the seat at the seat occupant is guided to the back of the seat.

[0015] Working principle: after foaming, the embedding groove 4 for the suction fan 3 and the position of the ventilation duct 5 are reserved, so that the suction fan 3 and the ventilation duct 5 can be installed inside the seat back without the need to use a bracket or other structure to install them on the outside of the seat back. The passing effect is also better than an external seat ventilation mechanism. In addition, the position of the ventilation duct 5 and the embedding groove 4 is sealed by an additional hot-pressed felt 6, so that they can be replaced and repaired in time when a fault occurs.

[0016] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
