[0032] Combine the following Figure 1-Figure 7 The structure of a charging device according to an embodiment of the present application is described.

[0033] like Figure 1 As shown, according to some embodiments of the present application, the charging device includes a charging base 10 and an air guide structure 20. The air guide structure 20 is installed on the charging base 10, and the air guide structure 20 abuts against the device to be charged 100 to form an air duct. Figure 2 As shown, the charging stand 10 is provided with a receiving chamber 11, and a first fan 31 and a second fan 32 are installed in the receiving chamber 11. The charging stand 10 is provided with a first air outlet 12 and a second air outlet 13, and the first air outlet 12 and the second air outlet 13 are both connected to the receiving chamber 11. The air guide structure 20 is provided with ventilation holes, and the ventilation holes are connected to the air duct.

[0034] When the device to be charged 100 is placed vertically on the wind guide structure 20 , the first fan 31 is in operation, the second fan 32 is in an off state, external air enters the accommodating chamber 11 from the first air outlet 12 , and the air in the accommodating chamber 11 flows to the air duct through the second air outlet 13 .

[0035] When the device to be charged 100 is placed horizontally on the wind guide structure 20 , the first fan 31 is in a closed state, and the second fan 32 is in a running state. External air enters the air duct from the ventilation hole and enters the accommodating chamber 11 through the second air outlet 13 , and the air in the accommodating chamber 11 is discharged from the first air outlet 12 .

[0036] The first fan 31 is an exhaust fan. Figure 3 As shown, when the device to be charged 100 is placed vertically on the wind guide structure, the first fan 31 is running, and air enters the accommodating cavity 11 from the first air outlet 12 and is transported to the air duct from the second air outlet 13. The second fan 32 is an exhaust fan, such as Figure 4 As shown, when the device to be charged 100 is placed horizontally on the wind guide structure, as shown in FIG. Figure 5As shown, the second fan 32 is running, and air enters the air duct from the ventilation hole and enters the accommodating cavity 11 from the second air outlet 13 and then is discharged from the first air outlet 12. Vertical placement means that after the device to be charged 100 is placed on the air guide structure 20, the length direction of the device to be charged 100 is consistent with the extension direction of the air guide structure 20; horizontal placement means that after the device to be charged 100 is placed on the air guide structure 20, the width direction of the device to be charged 100 is perpendicular to the extension direction of the air guide structure 20.

[0037] In some optional embodiments, a charging base is provided on the charging seat 10, and the charging base is provided with a charging coil, and the charging coil is used to charge the electronic device to be charged. The air guide structure 20 is installed on the charging base, and when in use, the device to be charged 100 is placed on the air guide structure 20, and an air duct is formed between the device to be charged 100, the air guide structure, and the charging base for air flow.

[0038] The first fan 31 is used to deliver external cold air from the first air outlet 12 to the accommodating chamber 11, so that the cold air is discharged from the second air outlet 13 through the accommodating chamber 11 into the air duct, thereby dissipating heat for the device 100 to be charged. The second fan 32 is used to discharge the air in the accommodating chamber 11 from the first air outlet 12, and the airflow enters the air duct along the ventilation hole and enters the accommodating chamber 11 through the second air outlet 13, so as to dissipate heat for the device 100 to be charged. The airflow directions of the first fan 31 and the second fan 32 are opposite during operation, so as to adapt to the devices 100 to be charged placed in different directions. Specifically, as Figure 3 As shown, when the device to be charged 100 is placed vertically on the air guide structure 20, the first fan 31 is running so that the air can contact the electronic device to be charged to the greatest extent when flowing along the air duct, thereby ensuring the heat dissipation effect. Figure 4 and Figure 5 As shown, when the device to be charged 100 is placed horizontally on the wind guide structure 20, the second fan 32 is running, and air enters the air duct from the outside of the wind guide structure 20 through the ventilation holes, ensuring that the air can still contact the entire electronic device, achieving a heat dissipation effect equivalent to that when placed vertically.

[0039] In some embodiments, a photoelectric switch, a proximity switch, or other sensors for detecting the presence or absence of a device to be charged 100 are installed at one end of the charging stand away from the second air outlet and at the other end close to the second air outlet, respectively, and the sensors are connected to both the first fan 31 and the second fan 32 in communication. When the two sensors detect the device to be charged 100, it is determined that the device to be charged 100 is placed vertically on the wind guide structure 20, and at this time, the first fan 31 is controlled to run, and the second fan 32 is not operated, so as to dissipate heat for the device to be charged 100. When only the sensor close to the second air outlet detects the device to be charged 100, and the sensor far from the second air outlet does not detect the device to be charged 100, it is determined that the device to be charged 100 is placed horizontally on the wind guide structure 20, and at this time, the second fan 32 is controlled to run, and the first fan 31 is not operated. In some other embodiments of the present application, other methods are used to determine the placement direction of the device to be charged 100, and this embodiment of the present application is not specifically limited.

[0040] In the charging device provided in the embodiment of the present application, when the device to be charged 100 is placed vertically on the charging base, only the first fan 31 works, and air enters from the first air outlet 12, enters the air duct through the accommodating cavity 11 and the second air outlet 13, thereby reducing the heat generated by the vertically placed device to be charged 100 during the charging process; when the device to be charged 100 is placed horizontally on the charging base, only the second fan 32 works, and air enters the air duct from the ventilation hole, enters the accommodating cavity 11 through the second air outlet 13, and is discharged from the first air outlet 12, thereby dissipating the heat of the horizontally placed device to be charged 100. Therefore, the charging device provided by the present application can achieve a good heat dissipation effect on the devices to be charged 100 placed in different directions, which helps to improve the user experience.

[0041] The charging device provided in the embodiment of the present application further includes a baffle 40, which is movably mounted on the wind guide structure 20. When the device 100 to be charged is placed vertically on the wind guide structure 20, the device 100 to be charged is pressed on the baffle 40, and the first fan 31 is in operation. When the device 100 to be charged is placed horizontally on the wind guide structure 20, the baffle 40 is located on one side of the device 100 to be charged, and the second fan 32 is in operation.

[0042] like Figure 5As shown, the baffle 40 extends along the width direction of the charging seat 10. When the device 100 to be charged is placed vertically on the air guide structure 20, the baffle 40 moves toward the charging seat 10 under the gravity of the device 100 to be charged, and the first fan 31 operates. When the device 100 to be charged is placed horizontally on the air guide structure 20 or the device 100 to be charged is not placed on the air guide structure 20, the baffle 40 automatically resets. When the charging seat 10 is in the working state, if the baffle 40 is in the reset state, the second fan 32 operates. In this way, the placement direction of the device 100 to be charged is distinguished according to the state of the baffle 40, and then the working state of the first fan 31 and the second fan 32 is controlled.

[0043] It should be noted that the baffle 40 can be a flat plate or a curved plate, which is not specifically limited in the embodiment of the present application. The distance between the baffle 40 and the second air outlet 13 is equivalent to the width of the device to be charged 100.

[0044] The charging device provided in the embodiment of the present application determines the placement direction of the device to be charged 100 by the relative relationship between the baffle 40 and the air guide structure 20, so as to start the corresponding fan operation. In addition, when the device to be charged 100 is placed horizontally on the air guide structure 20, the baffle 40 prevents a large amount of air from entering the air duct from above, and ensures that the air enters the air duct from the ventilation holes provided on the air guide structure 20, so as to minimize the heat generated by the device to be charged 100 during the charging process.

[0045] Based on the above embodiments, Figure 6 As shown, the baffle 40 is provided with a plurality of vent holes 41, and the vent holes 41 are communicated with the air duct.

[0046] The vent hole 41 may be a through hole in a circular or square shape, and the vent hole 41 is connected to the air duct so that air can flow smoothly along the air duct when the device to be charged 100 is placed vertically for charging. In some other embodiments of the present application, the device to be charged 100 is pressed on the baffle 40, and after the baffle 40 moves downward, there is still a certain gap between it and the charging substrate, which can also play a role in air flow.

[0047] In some embodiments of the present application, Figure 6 As shown, protrusions 42 are respectively provided on two opposite sides of the baffle 40, and a mounting hole is provided on the air guide structure 20, and the protrusions 42 are movably inserted in the mounting hole.

[0048] Specifically, Figure 5 and Figure 7As shown, the air guide structure 20 includes two side plates arranged opposite to each other, each of which is provided with a mounting hole, which can be a strip-shaped through-hole structure or a blind hole structure. A protrusion 42 is provided on each of the opposite sides of the baffle 40, and the protrusion 42 is inserted into the side plate on the corresponding side. The radial length of the mounting hole is greater than the protrusion 42, so that when the device to be charged 100 is pressed on the baffle 40, the protrusion 42 can move in the mounting hole along the radial direction of the mounting hole. Figure 7 As shown, the protrusion 42 is inserted into the mounting hole and protrudes out of the mounting hole. The portion of the protrusion 42 protruding out of the mounting hole can be used by the user to manually adjust the position of the baffle 40 according to the placement direction of the electronic device during use.

[0049] In some specific embodiments of the present application, an elastic member 43 is installed on the air guide structure 20, and a limit member 44 is installed at one end of the elastic member 43. A limit groove is provided on the baffle 40, and when the device to be charged 100 is placed horizontally on the air guide structure 20, the limit member 44 is clamped in the limit groove.

[0050] like Figure 7 As shown, the elastic member 43 is a spring, and the air guide structure 20 includes two side plates arranged opposite to each other, each side plate is provided with a mounting hole, and the baffle 40 is inserted into the mounting hole. When the device to be charged 100 is placed vertically on the air guide structure 20, the limit member 44 slides out of the limit groove under the gravity of the device to be charged 100, and the spring is in a compressed state. When the device to be charged 100 is moved away or placed horizontally on the air guide structure 20, the limit member 44 is clamped in the limit groove under the action of the rebound force of the spring to limit the position of the baffle 40 to prevent it from slipping or oscillating up and down.

[0051] Optionally, the baffle 40 is provided with a guide groove, and the limiting groove is located in the guide groove or at one end of the guide groove close to the charging seat 10 .

[0052] The guide groove may be a strip groove or a semicircular groove, and the limit groove is located in the middle or end of the guide groove. When the baffle 40 moves along the mounting hole, the limit member 44 slides in the guide groove, thereby preventing the baffle 40 from being skewed during movement.

[0053] Specifically, Figure 7 As shown, the limiting member 44 has a spherical surface, and the limiting groove is a spherical groove.

[0054] In some embodiments, the stopper 44 is spherical. In other embodiments, the stopper 44 is a column, and one end of the column away from the elastic member 43 is spherical. Of course, the stopper 44 may also have an arc surface, which is not specifically limited in the embodiments of the present application.

[0055] The limiting member 44 provided in the embodiment of the present application has a spherical surface, which facilitates sliding into or out of the limiting groove.

[0056] In some embodiments of the present application, there are two elastic members 43, which are arranged on opposite sides of the baffle 40 and at opposite ends of the elastic member 43. A stopper 44 is mounted on each elastic member 43.

[0057] like Figure 7 As shown, there are two springs. During the lifting and lowering process of the baffle 40, the two springs are compressed or rebounded, and the baffle 40 is prevented from tilting to one side by the two springs arranged on opposite sides of the baffle 40. When the limiting member 44 is clamped in the limiting groove, the two relatively arranged limiting members 44 make the force of the baffle 40 more balanced under the action of the springs, and the limiting is more stable.

[0058] In some embodiments of the present application, the first fan 31 and the second fan 32 are both axial flow fans and are arranged in parallel.

[0059] like Figure 2 As shown, the first fan 31 is further away from the first air outlet 12 than the second fan 32, so as to fully supply air to the second air outlet 13. The charging stand 10 includes a bottom plate and a side wall plate, the side wall plate is inclined relative to the bottom plate, and the first air outlet 12 is located on the side wall plate. The first air outlet 12 may include a plurality of strip holes or a plurality of circular holes, which is not specifically limited in the embodiment of the present application.

[0060] In some optional embodiments, the air guide structure 20 includes at least two side panels. At least the two side panels are arranged along the width direction of the charging stand 10, and each side panel is provided with a plurality of ventilation holes.

[0061] like Figure 5 As shown, the air guide structure 20 includes two side panels, which are located on opposite sides of the charging seat 10 along the width direction. Of course, the number of side panels can also be three or four, and the three or four side panels are arranged in parallel and arranged at intervals along the width direction of the charging seat 10.

[0062] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0063] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the claims and their equivalents.
