All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0043] Please refer to Figures 1-6 , a fan structure for improving the thermal comfort of a driver provided by an embodiment of the present invention includes a fan housing 5 detachably installed inside an automobile, and further includes a fan 1, a rocker 2, a rotating shaft 3, a fan base 4, a driving wheel 7, a first driving device 6, a second driving device 9, a driving shaft 8, and a slide rail 12;

[0044] The fan base 4 is fixed inside the fan housing 5, and the fan 1 is swingably installed on the fan base 4 through the rocker 2 and the rotating shaft 3;

[0045] The first driving device 6 is located inside the fan housing 5 and is used to drive the rotating shaft 3 to drive the fan 1 to swing;

[0046] The second driving device 9 is fixed on the fan housing 5, a driving shaft 8 is installed on the second driving device 9, and a driving wheel 7 is arranged on the driving shaft 8;

[0047] The slide rail 12 is detachably installed inside the automobile, wherein the second driving device 9 drives the driving wheel 7 to slide along the slide rail 12 through the driving shaft 8.

[0048] In an embodiment of the present invention, please refer to Figures 1-6, a fan magnet 10 is provided at the bottom of the fan housing 5, and the fan magnet 10 is magnetically fixed to the door magnet 13 or the A-pillar magnet 14 inside the vehicle;

[0049] The slide rail 12 is detachably mounted on the door 16 or the A-pillar 15 inside the vehicle.

[0050] The door magnet 13 is strip-shaped and fixed inside the skin along the lower edge of the side window of the door 16. Its long side is parallel to the lower edge of the window, and door mounting holes 19 are provided at both ends of the door magnet 13;

[0051] The A-pillar magnet 14 is strip-shaped and fixed inside the skin of the A-pillar 15. Its long side is parallel to the A-pillar 15, and A-pillar mounting holes 17 are provided at both ends of the A-pillar magnet 14.

[0052] The length of the slide rail 12 is greater than that of the door magnet 13 and the A-pillar magnet 14.

[0053] In an embodiment of the present invention, a fan coil 11, a door coil 20 and an A-pillar coil 18 are further included. The fan coil 11 is embedded in the center of the fan magnet 10 and is used to induce with the door coil 20 or the A-pillar coil 18 to realize wireless charging for the fan 1.

[0054] In an embodiment of the present invention, the first driving device 6 and the second driving device 9 are controlled by an in-vehicle control system to realize automatic adjustment of the swing of the fan 1 and the position on the slide rail 12.

[0055] In an embodiment of the present invention, the position of the fan housing 5 can be adjusted manually by sliding along the slide rail 12.

[0056] In an embodiment of the present invention, a depression matching with the slide rail 12 is provided at the bottom of the fan housing 5. The rectangular fan magnet 10 is embedded in the protruding parts on both sides, and the driving wheel 7 is installed in the depression.

[0057] The width of the depressed part is the same as the width of the slide rail 12.

[0058] The slide rail 12 includes a driving side 12-2 and a non-driving side 12-1, and the height of the driving side 12-2 is lower than that of the non-driving side 12-1;

[0059] When the slide rail 12 is assembled with the depression at the bottom of the fan housing 5, the driving side 12-2 is the side close to the second driving device 9, and the non-driving side 12-1 is the side close to the side where there is no driving shaft 8 in the depression at the bottom of the fan housing 5. Due to the existence of the driving shaft 8, the driving side 12-2 of the slide rail 12 will be relatively shorter than the non-driving side 12-1, so as to prevent the fan housing 5 from falling off the installation position.

[0060] The sliding rail 12 is further provided with sliding rail mounting holes 12-3 for being fixed to the vehicle door 16 or the A-pillar 15 through the vehicle door mounting holes 19 or the A-pillar mounting holes 17.

[0061] As Figure 1 shown, the fan 1 is rotatably connected to the rocker 2. The rotating shaft 3 has an interference fit with the rocker 2 and also has a transition fit with the fan seat 4. The fan seat 4 is fixed to the fan housing 5.

[0062] As Figure 2 and Figure 3 shown, the first driving device 6 is used to drive the rotating shaft 3 to rotate, so as to drive the rocker 2 and the fan 1 to swing; the second driving device 9 is placed inside the fan housing 5 and drives the driving wheel 7 to rotate through the driving shaft 8. Among them, both the first driving device 6 and the second driving device 9 adopt relatively small rotating motors and can drive the mechanism to rotate. The bottom of the fan housing 5 is in a concave shape (i.e., the recessed part). Among them, rectangular fan magnetic absorptions 10 are embedded in both protruding parts on both sides, and the driving wheel 7 and the driving shaft 8 are installed at the center of the recessed part; a fan coil 11 is embedded in the center of the fan magnetic absorption 10; the width of the recessed part is the same as the width of the sliding rail 12.

[0063] As Figure 4 shown, the sliding rail 12 is divided into a driving side 12-2, a non-driving side 12-1 and two sliding rail mounting holes 12-3. When installed, the driving side 12-2 is close to the second driving device 9 and the driving shaft 8. The fan housing 5 can move on the sliding rail 12 by the rotation of the driving wheel 7.

[0064] As Figure 5 and 6 shown, the vehicle door magnetic absorption 13 is strip-shaped and fixed inside the skin along the lower edge of the side window of the vehicle door 16. The long side of the vehicle door magnetic absorption 13 is parallel to the lower edge of the window. The two ends of the vehicle door magnetic absorption 13 are provided with vehicle door mounting holes 19. Two rows of electromagnetic coils, namely vehicle door coils 20, are embedded in the vehicle door magnetic absorption 13 and are respectively inductive with the two fan coils 11 for wireless charging.

[0065] The A-pillar magnetic absorption 14 is strip-shaped and fixed inside the skin of the vehicle interior A-pillar 15. The long side of the A-pillar magnetic absorption 14 is parallel to the A-pillar 15. The two ends of the A-pillar magnetic absorption 14 are provided with vehicle door mounting holes. Two rows of electromagnetic coils, namely A-pillar coils 18, are embedded in the A-pillar magnetic absorption 14 and are respectively inductive with the two fan coils 11 for wireless charging.

[0066] The length of the sliding rail 12 is slightly longer than that of the vehicle door magnetic absorption 13 and the A-pillar magnetic absorption 14. The sliding rail mounting holes 12-3 can be respectively connected to the vehicle door mounting holes 19 and the A-pillar mounting holes 17 and are thus fixed inside the vehicle.

[0067] As a preferred embodiment provided by the present invention, both the first driving device 6 and the second driving device 9 are controlled by an in-vehicle control system, enabling automatic adjustment of the fan structure during driving; the position of the fan housing 5 on the slide rail 12 can also be manually adjusted by the driver.

[0068] The working principle of the present invention is as follows:

[0069] The driver installs the slide rail 12 on the door magnetic attraction 13 or the A-pillar magnetic attraction 14. The installation method is to align the slide rail installation hole 12-3 with the door installation hole 19 or the A-pillar installation hole 17 and connect them. The fan housing 5 and other internal devices are installed on the slide rail 12 together. The installation method is to align the groove of the fan housing 5 with the slide rail 12, where the driving side 12-2 of the slide rail 12 is close to the side where the built-in second driving device 9 in the fan structure is located during installation. At this time, the fan magnetic attractions 10 on both sides of the bottom of the fan housing 5 attract the door magnetic attraction 13 or the A-pillar magnetic attraction 14, enabling the fan housing 5 to be fixed in the vehicle, and the fan coil 11 and the door coil 20 or the A-pillar coil 18 interact to charge.

[0070] The in-vehicle control system has a built-in control strategy. When it controls the fan structure to start, the fan 1 starts to rotate, and the first driving device 6 drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the rocker 2 and the fan to swing back and forth, achieving large-range air blowing; the installation control strategy of the second driving device 9 rotates the driving shaft 8, thereby driving the driving wheel 7 to rotate, enabling the driving wheel 7 to roll back and forth on the slide rail 12. When the driver adjusts the position relative to the fan structure, the fan housing 5 can be manually slid along the slide rail 12, and at this time, the driving wheel 7 rolls on the slide rail 12.

[0071] As Figure 7 shown, when the fan is attracted to the door magnetic attraction, before the fan structure of the present invention is turned on, there is a large area of high-temperature region on the driver's arm on the window side. After the fan is turned on (the fan speed is 1000 rpm), the high-temperature region of the driver's arm has been greatly alleviated. In addition, the temperature of the entire body part of the driver on the window side has decreased, greatly improving the human body cooling rate.

[0072] As Figure 8 shown, before the fan structure of the present invention is turned on, the surface temperature of the driver's body is stable at about 29°. After the fan is turned on (the fan speed is 1000 rpm), the surface temperature of the driver's body can be stable at about 24°, further proving the effectiveness of the present invention.

[0073] It should be noted that in the present invention, unless otherwise clearly specified and defined, terms such as "sliding", "rotating", "fixing", "provided with" should be understood in a broad sense. For example, it can be a welded connection, a bolt connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0074] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
