Description

Technical Field

[0001] The utility model relates to the technical field of seat fan equipment, in particular to a fan for ventilating seats. Background Art

[0002] Car seats are one of the most important automotive components, directly affecting the comfort and safety of drivers and passengers during their use of the car. To improve the riding comfort of drivers and passengers, most car seats on the market are equipped with ventilation devices to achieve seat ventilation functions.

[0003] A search revealed a Chinese patent application with publication number CN 221698547 U, which discloses a ventilation device for a car seat. The device comprises a car seat body, a mounting cavity defined on the inner side of the car seat body, a first comfort pad fixedly connected to the outer side of the car seat body, a bottom ventilation assembly fixedly connected to the inner side of the mounting cavity, a second comfort pad fixedly connected to the outer side of the car seat body, a mounting frame fixedly connected to the inner side of the mounting cavity, a linear transmission assembly fixedly connected to the bottom end of the mounting frame, a connecting rod fixedly connected to the front end of the linear transmission assembly, a side ventilation fan fixedly connected to the outer side of the connecting rod, and a limiter assembly fixedly connected to the front end of the side ventilation fan. This ventilation device for a car seat has the advantages of being able to adjust the ventilation position to achieve the optimal ventilation position.

[0004] The inventor has discovered that the above technology adjusts the position of the fan by setting a mechanical structure so that the fan is in an active state. Although this method can adjust the optimal ventilation position, due to the instability of the fan, it may be damaged by vibration during long-term driving. At the same time, the internal space of the seat is limited. When it is necessary to reserve space for the fan's activity, it will cause inconvenience in the installation of other structures inside the seat, increasing the overall design difficulty of the existing seat. Therefore, the utility model proposes a fan for ventilated seats. Utility Model Content

A clamping block 15 is welded and fixed on the right side of the first fan 1, and a connecting block 13 is welded and fixed on the left side of the second fan 2. The left part of the connecting block 13 is clamped inside the clamping block 15. The air outlets of the first fan 1 and the second fan 2 are both embedded with a wind shield 11. Two sets of trapezoidal covers 10 are integrally formed at the upper and lower positions on the front side of the wind shield 11. A wind collecting cover 12 is integrally formed at the front of the trapezoidal cover 10 and is located at the wind shield. An upper air outlet duct 5 is welded and fixed to the front of the air collecting hood 12 on the upper side of the wind plate 11, and a lower air outlet duct 8 is welded and fixed to the front of the air collecting hood 12 located on the lower side of the wind shield 11. Several groups of upper air balancing ducts 4 are welded and fixed at equal distances on the front side of the upper air outlet duct 5, and several groups of lower air balancing ducts 9 are welded and fixed at equal distances on the front side of the lower air outlet duct 8. Fixing strips 3 are welded and fixed to the left and right ends of the upper air balancing duct 4 and the lower air balancing duct 9. Solenoid valves are installed at the ends of the upper air outlet duct 5 and the lower air outlet duct 8 on the first fan 1 and the second fan 2.

[0031] like Figure 1 and Figure 2 As shown, several groups of air outlet holes are equidistantly provided on the front sides of the upper and lower air ducts 4, 9. The cross-section of the fixing strip 3 is L-shaped when viewed from above, and screw holes are provided on the fixing strip 3 for convenient screw penetration. The uniform air outlet holes ensure the uniformity of the air outlet, thereby improving the comfort of the personnel. The upper and lower air ducts 4, 9 can be fixed in the seat by means of the fixing strip 3 and the screw holes to ensure their stability.

[0032] like Figure 1 and Figure 2 As shown, a fixing plate for fixation is welded to the left side of the first fan 1 and the right side of the second fan 2. The fixing plate is provided with a strip slot for adjustment. External screws can be passed through the strip slots on the fixing plate to fix the first fan 1 and the second fan 2 in the seat to ensure the stability of the fan during driving.
