Description

Technical Field

[0001] The utility model relates to a protection structure for an in - seat fan of an automobile seat, belonging to the technical field of automobiles. Background Technique

[0002] An automobile seat is an important component inside an automobile, aiming to provide a comfortable riding experience for drivers and passengers. Modern automobile seats usually have various adjustment functions, such as the adjustment of height, inclination, and backrest angle. Some high - end models are also equipped with heating and ventilation functions to adapt to different climate conditions. An automobile seat with an in - seat fan can effectively improve the ventilation performance by arranging a fan inside the seat, helping the seat to stay dry. Especially in hot summer or during long - term driving, it can significantly improve the riding comfort.

[0003] The authorized announcement number (CN221340322U) discloses an automobile seat ventilation fan, including a mounting frame; the mounting frame: sliding plates are respectively slidably connected to the upper ends thereof, vertical plates are arranged at the lower ends of the sliding plates, sliding grooves corresponding to the vertical plates are respectively formed inside the mounting frame, rotating shafts are respectively rotatably connected to the inside of the vertical plates through bearings, a mounting plate is arranged between the two rotating shafts, fan shells are arranged in the mounting holes inside the mounting plate, a first motor is arranged at the lower side inside each fan shell through a connecting brace, a turntable is arranged at the upper end of the output shaft of each first motor, and blades are arranged on the outer arc surface of each turntable; wherein: a control switch group is further included, the control switch group is located outside the mounting frame, the input end of the control switch group is electrically connected to an external power supply.

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1

[0029] As Figures 1-6 shown, the embodiment of the present utility model provides a protective structure for an in - vehicle seat fan, which includes a protective cylinder 1 and a fan body 2. The fan body 2 is located inside the protective cylinder 1. Connecting holes 3 are opened around the top of the protective cylinder 1. A protective component 4 is arranged on the top of the protective cylinder 1. The protective component 4 includes a protective plate 401, bolt holes 402, assembly columns 403, connecting bolts 404, rigid springs 405 and connecting sleeves 406. The protective plate 401 is located on the top of the protective cylinder 1. The bolt holes 402 are opened around the top of the protective plate 401. The assembly columns 403 are fixedly connected to the periphery of the bottom of the protective plate 401. The bolt holes 402 communicate with the assembly columns 403. The connecting bolts 404 are located inside the bolt holes 402. The lower end of the connecting bolt 404 is threadedly connected to the inside of the assembly column 403. The rigid springs 405 are fixedly connected to the inside of the connecting holes 3. Four connecting sleeves 406 are fixedly connected to the upper ends of the four rigid springs 405. The lower ends of the four connecting bolts 404 penetrate through the assembly columns 403 and extend to the bottom of the assembly columns 403. The lower ends of the four connecting bolts 404 are threadedly connected to the inside of the four connecting sleeves 406. The connecting sleeves 406 and the assembly columns 403 are connected by the connecting bolts 404.

[0030] Through the setting of the protective component 4, the fan body 2 can be protected, preventing the fan body 2 from being damaged in collisions or impacts, ensuring that the fan body 2 continues to operate normally, thereby maintaining the ventilation function of the seat. Secondly, it can reduce the direct impact of external shocks on passengers and lower the risk of accidental injury. In addition, it can also enhance the overall durability of the seat, avoid the maintenance cost caused by the damage of the fan body 2, and improve the use value and riding experience of the vehicle.

[0031] Embodiment 2

[0032] In one embodiment, guide blocks 407 are fixedly connected to the peripheries of the surfaces of the four connecting sleeves 406. Guide grooves 408 are provided inside the four connecting holes 3. The guide blocks 407 are slidably connected to the inside of the guide grooves 408. To cooperate with the movement of the connecting sleeves 406, ventilation holes 5 are provided at the top of the protection plate 401. The number of the ventilation holes 5 is multiple, and they are equidistantly distributed on the surface of the protection plate 401. Ventilation plates 6 are fixedly installed at both the top and the bottom of the protection cylinder 1. The blower body 2 is movably connected to the inside of the ventilation plates 6. Positioning bolts 7 are fixedly installed on the peripheries of the surface of the protection cylinder 1. The lower ends of the positioning bolts 7 penetrate through the protection cylinder 1 and extend to the bottom of the protection cylinder 1.

[0033] Through the arrangement of the guide blocks 407 and the guide grooves 408, the stability during the movement of the connecting sleeves 406 can be improved, and the deviation of the connecting sleeves 406, the assembly columns 403 and the connecting bolts 404 during movement can be prevented. Through the arrangement of the ventilation holes 5, air circulation can be ensured. Through the arrangement of the positioning bolts 7, the protection cylinder 1 can be conveniently assembled and fixed to an external structure.

[0034] When the utility model is in operation: after the protection cylinder 1 and the blower body 2 are assembled at the use position through the positioning bolts 7, the assembly columns 403 are inserted into the inside of the connecting holes 3, and then the connecting bolts 404 are inserted into the bolt holes 402, and tools are used to screw the connecting bolts 404 so that they are threadedly connected to the inside of the assembly columns 403 and the connecting sleeves 406, forming a connection between the assembly columns 403 and the connecting sleeves 406. During use, the rotation of the blower body 2 drives the air to flow, and the air is conveyed out through the ventilation plates 6 and the positioning bolts 7. When an external collision or extrusion occurs, the protection plate 401 will deviate towards the protection cylinder 1 under the influence of the pressure. When the protection plate 401 moves, it drives the assembly columns 403 to move. During the movement of the assembly columns 403, the connecting bolts 404 and the connecting sleeves 406 will be driven to move. Through the movement of the connecting sleeves 406, the rigid springs 405 will be squeezed. After being squeezed, the rigid springs 405 will deform and absorb the pressure, thus achieving a buffering effect.

[0035] The above is only the specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
