Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to a wind guiding structure and a device with the wind guiding structure. Background Art

[0002] With the improvement of people's living standards, the use of air conditioners has become more and more popular, and consumers have higher and higher requirements for the appearance and various functions of air conditioners. However, in existing air conditioners, the air deflector is usually connected to the power output end of the motor through a drive shaft, or to the power output end of a transmission mechanism that moves under the drive of the motor. When the motor drives the air deflector to rotate through the transmission mechanism or directly drives the air deflector to rotate, the load on the drive shaft is relatively heavy. Under the action of a relatively high wind speed, the phenomenon of the air deflector shaking is likely to occur, thereby reducing the reliability of the movement of the air deflector. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the air deflector is prone to shaking during air outlet and the movement reliability is reduced in the prior art, so as to provide a wind guiding structure and a device with the wind guiding structure that are not prone to shaking during air outlet and have improved movement reliability.

[0004] A wind guiding structure includes:

[0005] An air deflector;

[0006] A swing structure fixedly connected to at least one end of the air deflector, and including a drive shaft, a support shaft, and a connection structure connecting the drive shaft and the support shaft.

[0007] The connection structure is fixedly connected to the air deflector.

[0008] The swing structure is fixedly connected to one end of the air deflector; the wind guiding structure further includes a bearing shaft fixedly connected to the other side of the air deflector.

[0009] The swing structures are respectively fixedly connected to both sides of the air deflector.

[0010] The support shaft, the drive shaft, and the connection structure are integrally formed.

[0011] It further includes a power device and a transmission mechanism. The transmission mechanism connects the power device and the swing structure and is adapted to drive the swing structure to rotate under the drive of the power device.

[0012] It further includes at least two rotating grooves provided on the transmission mechanism. The drive shaft and the support shaft are respectively inserted into the corresponding rotating grooves, and at least the drive shaft is linked with the transmission mechanism through the corresponding rotating groove.

[0013] The support shaft and the drive shaft are respectively linked with the transmission mechanism through the corresponding rotation grooves.

[0014] The transmission mechanism includes:

[0015] A first gear connected to the output shaft of the power device;

[0016] A second gear meshed and connected with the first gear, and the rotation groove is provided on the second gear.

[0017] Two convex columns are fixedly connected to the second gear, and the rotation grooves are respectively formed on the end parts of the two convex columns that cooperate with the swing structure.

[0018] The two convex columns are integrally formed with the second gear.

[0019] It further includes:

[0020] A drive box, and a groove or a through hole is provided on the drive box, and the groove or the through hole is rotationally connected with one of the convex columns in a matching manner, and the one convex column is the convex column that is connected with the support shaft in a matching manner.

[0021] It further includes a limiting structure provided on the drive box and located on both sides of the second gear, and is adapted to limit the rotation angle of the second gear.

[0022] The limiting structure is a limiting rib and / or a microswitch.

[0023] A device with a wind guiding structure includes the wind guiding structure as described above.

[0024] It further includes a support, and an air outlet is formed on the support, and the wind guiding structure is provided at the air outlet.

[0025] The device with the wind guiding structure is an air conditioner.

[0026] The technical solution of the present invention has the following advantages:

[0027] 1. The air guiding structure provided by the present invention includes: an air guiding plate; a swinging structure fixedly connected to at least one end of the air guiding plate, and the swinging structure includes a driving shaft, a supporting shaft, and a connecting structure connecting the driving shaft and the supporting shaft. By providing a fixedly connected swinging structure at at least one end of the air guiding plate, the swinging structure includes a driving shaft, a supporting shaft, and a connecting structure connecting the driving shaft and the supporting shaft. The driving shaft can be connected to the power output end of the driving device, and the supporting shaft can be connected to the power output end or the structure to be installed. Then, when the air guiding plate rotates, the driving shaft and the supporting shaft jointly support the air guiding plate, so that the gravity of the air guiding plate can be dispersed to the driving shaft and the supporting shaft, rather than being supported by only one driving shaft, reducing the load at the rotating shaft, enabling more stable support for the air guiding plate. At the same time, since the driving device drives the swinging structure, it is equivalent to reducing the transmission ratio and increasing the transmission torque, capable of achieving the effect of driving a large air guiding plate with the torque of a small motor, and can also play a good supporting role for a larger and heavier air guiding plate, preventing the shaking of the air guiding plate and improving the reliability of the movement of the air guiding plate.

[0028] 2. In the air guiding structure provided by the present invention, the swinging structure is fixedly connected to one end of the air guiding plate; the air guiding structure further includes a bearing shaft fixedly connected to the other side of the air guiding plate. By fixedly connecting the swinging structure to one end of the air guiding plate and the bearing shaft to the other end of the air guiding plate, the air guiding structure occupies less space while ensuring the reliability of the movement of the air guiding plate.

[0029] 3. In the air guiding structure provided by the present invention, the swinging structures are respectively fixedly connected to both sides of the air guiding plate. By respectively fixedly connecting the swinging structures to both sides of the air guiding plate, the rotation of the air guiding plate is more stable and the reliability of the movement of the air guiding plate is higher.

[0030] 4. In the air guiding structure provided by the present invention, the supporting shaft, the driving shaft, and the connecting structure are integrally formed. By integrally forming the supporting shaft, the driving shaft, and the connecting structure, there is no gap between each component, and the movement virtual position is smaller when driving the air guiding plate to move.

[0031] 5. The air guiding structure provided by the present invention further includes a power device and a transmission mechanism. The transmission mechanism connects the power device and the swinging structure and is adapted to drive the swinging structure to rotate under the drive of the power device. By providing a transmission mechanism between the power device and the swinging structure, the self-locking force of the air guiding plate is greater than that of the air guiding plate directly driven by the power device, further preventing the shaking of the air guiding plate.

[0032] 6. The air guiding structure provided by the present invention further includes at least two rotating grooves provided on the transmission mechanism. The driving shaft and the supporting shaft are respectively inserted into the corresponding rotating grooves, and at least the driving shaft is linked with the transmission mechanism through the corresponding rotating groove. By setting at least the driving shaft to be linked with the transmission mechanism, when the transmission mechanism drives the air guiding plate to move, the movement virtual position between components is small, making the movement of the air guiding plate more stable.

[0033] 7. For the air guiding structure provided by the present invention, the supporting shaft and the driving shaft are respectively linked with the transmission mechanism through the corresponding rotating grooves. By linking the supporting shaft, the driving shaft and the transmission mechanism, the movement virtual position between the transmission mechanism and the air guiding plate is smaller, further improving the stability and reliability of the movement of the air guiding plate.

[0034] 8. For the air guiding structure provided by the present invention, the two convex columns and the second gear are integrally formed. By integrally forming the convex columns and the second gear, there is no gap between each component, and the movement virtual position is small when driving the air guiding plate to move.

[0035] 9. The air guiding structure provided by the present invention further includes: a driving box. The driving box is provided with a groove or a through hole, and the groove or the through hole is rotationally connected with one of the convex columns in a matching manner. The one convex column is the convex column that is connected with the supporting shaft in a matching manner. By setting the driving box and rotating the air guiding plate relative to the driving box, the air guiding structure can be assembled as a component, making the overall structure of the air guiding structure more compact.

[0036] 10. The air guiding structure provided by the present invention further includes a limiting structure provided on the driving box and located on both sides of the second gear, suitable for limiting the rotation angle of the second gear. By providing the limiting structure on the driving box, the rotation angle of the second gear can be accurately limited, thereby improving the rotation accuracy of the air guiding plate.

Detailed implementation manners

[0045] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. 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.

[0046] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] As Figure 1 - Figure 5 shown, in this embodiment, an air guiding structure is provided, including: an air guiding plate 1 and a swinging structure 4.

[0048] The swinging structure 4 is fixedly connected to at least one end of the air guiding plate 1 and includes a drive shaft 2, a support shaft 3, and a connection structure 14 connecting the drive shaft 2 and the support shaft 3.

[0049] By providing a swing structure 4 fixedly connected to at least one end of the air deflector 1, the swing structure 4 includes a drive shaft 2, a support shaft 3, and a connection structure 14 connecting the drive shaft 2 and the support shaft 3. The drive shaft 2 can be connected to the power output end of the driving device, and the support shaft 3 can be connected to the power output end or the structure to be installed. Then, when the air deflector 1 rotates, the drive shaft 2 and the support shaft 3 jointly support the air deflector 1, so that the gravity of the air deflector 1 can be dispersed onto the drive shaft 2 and the support shaft 3, rather than being supported only by one drive shaft 2. This reduces the load at the rotation axis and can provide a more stable support for the air deflector 1. At the same time, since the driving device drives the swing structure 4, it is equivalent to reducing the transmission ratio and increasing the transmission torque, enabling the effect of a small motor torque driving the large air deflector 1 to move. For a larger and heavier air deflector 1, it can also provide good support, prevent the air deflector 1 from shaking, and improve the reliability of the air deflector 1 movement.

[0050] In this embodiment, the connection structure 14 is fixedly connected to the air deflector 1, and a support shaft 3 and a drive shaft 2 are respectively provided at both ends of the connection structure 14. As a variant implementation, it can also be that the support shaft 3 is provided with two or more. As a variable implementation, it can also be that the support shaft 3 is fixedly connected to the air deflector 1, one end of the connection structure 14 is fixedly connected to the support shaft 3, and the other end of the connection structure 14 is fixedly connected to the drive shaft 2; or the drive shaft 2 is fixedly connected to the air deflector 1, one end of the connection structure 14 is fixedly connected to the drive shaft 2, and the other end of the connection structure 14 is fixedly connected to the support shaft 3.

[0051] As Figure 1 shown, in this embodiment, there is one air deflector 1, and the swing structure 4 is fixedly connected to one end of the air deflector 1; the air guiding structure further includes a bearing shaft 5 fixedly connected to the other side of the air deflector 1. By fixedly connecting the swing structure 4 to one end of the air deflector 1 and the bearing shaft 5 to the other end of the air deflector 1, the air guiding structure occupies less space while ensuring the movement reliability of the air deflector 1.

[0052] As a variant implementation, it can also be that swing structures 4 are respectively fixedly connected to both sides of the air deflector 1. By respectively fixedly connecting the swing structures 4 to both sides of the air deflector 1, the rotation of the air deflector 1 is more stable, and the reliability of the air deflector 1 movement is higher.

[0053] As a transformable embodiment, it is also possible that there are two air deflector plates 1. One end of one air deflector plate 1 is fixedly connected to a swing structure 4, and the other end is fixedly connected to a bearing shaft 5. One end of the other air deflector plate 1 is fixedly connected to a bearing shaft 5, and the other end is fixedly connected to a swing structure 4. That is, the swing structures 4 and the bearing shafts 5 of the two air deflector plates 1 are arranged in an interleaved manner, so that the occupied space of the air guiding structure is smaller and the movement is more reliable. As a transformable embodiment, it is also possible that the number of air deflector plates 1 can be specifically set according to factors such as the size of the air outlet 13.

[0054] In this embodiment, the support shaft 3, the drive shaft 2 and the connection structure 14 are integrally formed. By integrally forming the support shaft 3, the drive shaft 2 and the connection structure 14, there is no gap between the components, and the movement virtual position is smaller when driving the air deflector plate 1 to move. As a transformable embodiment, it is also possible that the support shaft 3, the drive shaft 2 and the connection structure 14 are separately fixedly connected.

[0055] The air guiding structure in this embodiment further includes a driving device. The driving device includes a power device and a transmission mechanism. The transmission mechanism connects the power device and the swing structure 4 and is adapted to drive the swing structure 4 to rotate under the drive of the power device. The power device in this embodiment is a motor. By arranging a transmission mechanism between the power device and the swing structure 4, the self-locking force of the air deflector plate 1 is greater than that of the air deflector plate 1 directly driven by the power device, further preventing the air deflector plate 1 from shaking. As a transformable embodiment, it is also possible that no transmission mechanism is provided, and the power device directly drives the swing structure 4 to drive the air deflector plate 1 to move.

[0056] The air guiding structure in this embodiment further includes at least two rotating grooves 6 provided on the transmission mechanism. The drive shaft 2 and the support shaft 3 are respectively inserted into the corresponding rotating grooves 6, and at least the drive shaft 2 is linked with the transmission mechanism through the corresponding rotating groove 6. By arranging at least the drive shaft 2 to be linked with the transmission mechanism, when the transmission mechanism drives the air deflector plate 1 to move, the movement virtual position between the components is smaller, and the movement of the air deflector plate 1 is more stable. Specifically, there are two rotating grooves 6 in this embodiment, which are respectively inserted corresponding to the drive shaft 2 and the support shaft 3. As a transformable embodiment, it is also possible that rotating grooves 6 are opened on the end faces of the drive shaft 2 and the support shaft 3 connected to the transmission mechanism, and rotating blocks are provided on the transmission mechanism to cooperate with the rotating grooves 6.

[0057] In order to make the movement of the air deflector plate 1 more reliable and stable, the support shaft 3 and the drive shaft 2 in this embodiment are respectively linked with the transmission mechanism through the corresponding rotating grooves 6.

[0058] Such as Figure 3As shown in the figure, the transmission mechanism in this embodiment is a double-gear mechanism, including: a first gear 7 connected to the output shaft of the power device; a second gear 8 meshed with the first gear 7, and a rotation groove 6 is provided on the second gear 8. As an alternative embodiment, the transmission mechanism can also be a crank and connecting rod device.

[0059] Specifically, as Figure 4 shown in the figure, two convex columns 9 are fixedly connected to the second gear 8 in this embodiment. Rotation grooves 6 are respectively formed at the ends of the two convex columns 9 that cooperate with the swing structure 4. By fixing the support shaft 3 and the drive shaft 2 on the same gear at the same time, the fitting clearance between parts is reduced. As an alternative embodiment, the rotation groove 6 can also be directly formed on the second gear 8. As an alternative embodiment, there can also be one rotation groove 6 provided on the second gear 8, which is connected to the drive shaft 2 in a mating manner, and another rotation groove 6 is provided on the structure to be installed, which is connected to the support shaft 3 in a mating manner.

[0060] The two convex columns 9 in this embodiment are integrally formed with the second gear 8. By integrally forming the convex columns 9 and the second gear 8, there is no gap between the components, and the movement clearance is relatively small when driving the air deflector 1 to move. As an alternative embodiment, the convex columns 9 can also be fixedly connected to the second gear 8 separately.

[0061] As Figure 2 shown in the figure, the air guiding structure in this embodiment further includes: a driving box 10, and the driving box 10 is provided with a groove or a through hole, and the groove or the through hole is rotatably connected to one of the convex columns 9 in a mating manner, and one of the convex columns 9 is the convex column 9 that is connected to the support shaft 3 in a mating manner. By providing the driving box 10, the air deflector 1 rotates relative to the driving box 10, so that the air guiding structure can be assembled as a component, making the overall structure of the air guiding structure more compact. As an alternative embodiment, the convex column 9 that is connected to the support shaft 3 in a mating manner can also be fixedly connected to the driving box 10, and the second gear 8 rotates around the outer peripheral wall of the convex column 9.

[0062] Specifically, two driving boxes 10 are provided in this embodiment. One driving box 10 is connected to the swing structure 4, and the other driving box 10 is fixedly connected to the bearing shaft 5. As an alternative embodiment, only one driving box 10 can be provided, which is connected to the swing structure 4, and the bearing shaft 5 is directly fixedly connected to the structure to be installed.

[0063] The air guiding structure in this embodiment further includes a limiting structure, which is arranged on the driving box 10, on both sides of the second gear 8, and is suitable for limiting the rotation angle of the second gear 8. By arranging the limiting structure on the driving box 10, the rotation angle of the second gear 8 can be accurately limited, thereby improving the rotation accuracy of the air guiding plate 1. Specifically, the limiting structure in this embodiment is a limiting rib 11. As an alternative embodiment, it can also be that the limiting structure is a microswitch; or the limiting structure is a combination of a limiting rib 11 and a microswitch.

[0064] This embodiment also provides a device with an air guiding structure, including the air guiding structure as described above.

[0065] As Figure 5 shown, the device with an air guiding structure in this embodiment further includes a support 12. An air outlet 13 is formed on the support 12, and the air guiding structure is arranged at the air outlet 13. Specifically, a driving box 10 is fixedly connected to the support 12, the transmission mechanism and the power device are arranged on the driving box 10, and the air guiding plate 1 is connected to the second gear 8 on the driving box 10 through a swinging structure 4.

[0066] The device with an air guiding structure in this embodiment is an air conditioner. As an alternative embodiment, it can also be that the device with an air guiding structure is an air cooler.

[0067] When installing the air guiding structure in this embodiment, the driving box 10 can be first fixed to both sides of the support 12 by screws or buckles, and then one end of the air guiding plate 1 is inserted into two rotation slots 6 of the corresponding second gear 8 in the left driving box 10. Then, the other end is deformed by extrusion, and then the bearing shaft 5 on the right side of the air guiding plate 1 is inserted into the right driving box 10. Or, the air guiding plate 1 and the driving box 10 can also be installed first, that is, the support shaft 3 and the driving shaft 2 on one side of the air guiding plate 1 are respectively installed in the rotation slots 6 of the driving box 10 on the same side, and then the bearing shaft 5 on the other side of the air guiding plate 1 is installed with the driving box 10 on the same side. Then, the installed air guiding plate 1 and the driving box 10 assembly are fixedly installed on the side wall of the air outlet 13 of the support 12.

[0068] After installation, the motor drives the first gear 7 to rotate. The first gear 7 meshes with the second gear 8 for transmission. Two convex columns 9 are arranged on the second gear 8, and rotation slots 6 are arranged on the convex columns 9, which cooperate with the support shaft 3 and the rotating shaft on the air guiding plate 1 respectively, so that the entire air guiding plate 1 can rotate in the groove or through hole of the driving box 10 with the convex column 9 cooperating with the support shaft 3 as the axis, and the rotation movement of the air guiding plate 1 is realized under the action of the motor to achieve the air sweeping effect. Since the support shaft 3 and the driving shaft 2 on the air guiding plate 1 cooperate with the rotation slots 6 on the second gear 8, the cumulative movement virtual position of the assembled parts is reduced, so that the air guiding plate 1 can move smoothly.

[0069] The length of the swing structure 4 in this embodiment needs to be adjusted according to the actual design space, the deviation of the center of gravity of the air deflector 1 from the support shaft 3, and the weight. The farther the center of gravity deviates from the support shaft 3 and the greater the weight, the longer the length of the swing structure 4. Reasonably setting the length of the swing structure 4 can effectively alleviate or even eliminate the jitter of the air deflector 1, and further improve the reliability of the air guiding structure.

[0070] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
