[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, an embodiment of the present invention provides an air guide device, including: an air guide plate 10, which is rotatable back and forth along an opening rotation direction and a closing rotation direction, and the air guide plate 10 has an open state and a closed state; a driving unit 20, which is drivingly connected to one end of the air guide plate 10 to drive the air guide plate 10 to rotate; a damping device 30, which is connected to the other end of the air guide plate 10 to apply an auxiliary torque to the air guide plate 10; wherein, when the air guide plate 10 is in a closed state, the direction of the auxiliary torque is the closing rotation direction.

[0034] In this embodiment, when the air deflector 10 is in the open state, the driving unit 20 can drive the air deflector 10 to rotate, so as to adjust the air outlet angle; when the air deflector 10 is converted from the open state to the closed state, the damping device 30 disposed at the other end of the air deflector 10 applies an auxiliary torque in the same direction as the closing rotation direction to the air deflector 10, thereby avoiding the situation in the prior art that the end without the damping device 30 will sag due to problems such as part torsion and gravity factors, resulting in the air deflector 10 not being tightly closed in the closed state. In this way, the damping device 30 disposed at one end of the air deflector 10 provides a force in a tightening direction, i.e., a closing direction, to the air deflector 10 in the closed state, so that the air deflector 10 can be tightly closed under the action of the auxiliary torque, thereby improving the reliability of the closing of the air deflector 10, and the air deflector 10 can still be tightly closed after long-term use, thereby improving the continuity of reliable operation.

[0035] like Figure 1 As shown, the wind deflector 10 includes a plate body 11 and a first arm 12 and a second arm 13 respectively arranged at both ends of the plate body 11, the rotation center lines of the first arm 12 and the second arm 13 are coaxial, the driving part 20 is drivingly connected to the first arm 12, and the damping device 30 is connected to the second arm 13; the wind deflector also includes a support part 40, and the driving part 20 and the damping device 30 are arranged on the support part 40 at intervals. In this arrangement, the coaxiality of the rotation center lines of the first arm 12 and the second arm 13, and the driving part 20 and the damping device 30 are arranged on the support part 40 at intervals, ensure the tightness of the wind deflector 10 to be closed.

[0036] Specifically, the damping device 30 includes: a first damping member 31, the first damping member 31 applies a first torque to the second arm 13 in the closing rotation direction; and a second damping member 32, the second damping member 32 applies a second torque to the second arm 13 in the opening rotation direction. In this embodiment, the first damping member 31 and the second damping member 32 provide two opposite torques respectively, so as to prevent the torque provided by the first damping member 31 that applies torque to the second arm 13 in the closing rotation direction from acting in reverse on the side of the air deflector 10 provided with the damping device 30 when the air deflector 10 is switched from the closed state to the open state, so that the side of the air deflector 10 provided with the damping device 30 is subjected to a greater force, resulting in the air deflector 10 jumping during the opening process. By providing the second damping member 32, it can be ensured that the reverse force provided by the first torque will not be too large during the process of the air deflector 10 switching from the closed state to the open state. Accordingly, the first damping member 31 can also ensure that the reverse force provided by the second torque will not be too large during the process of the air deflector 10 switching from the open state to the closed state, and has a certain limiting effect on the rotation of the air deflector 10, making the rotation of the air deflector 10 more stable. The sum of the first torque and the second torque is the auxiliary torque.

[0037] like Figure 5 As shown, the first damper 31 and the second damper 32 are both springs in a compressed state, the elastic modulus of the first damper 31 is k1, and the elastic modulus of the second damper 32 is k2, k1≥k2; when the air deflector 10 is in a closed state, the compression deformation of the first damper 31 is X1, and the compression deformation of the second damper 32 is X2, X1>X2. This arrangement ensures that when the air deflector 10 is in a closed state, the direction of the auxiliary torque formed by the sum of the first torque provided by the first damper 31 and the second torque provided by the second damper 32 is the closing rotation direction, thereby ensuring that the damping device 30 can assist the air deflector 10 in a tight closure, thereby improving the reliability of the damping device 30.

[0038] like Figure 8 As shown, the distance between the center of gravity and the rotation center line of the air guide plate 10 is r, and the distance between the center of gravity and the rotation center line in the horizontal direction when the sum of the first torque and the second torque is zero is d, and 0.5r≤d≤r.

[0039] In this embodiment, when the sum of the first torque and the second torque is zero, the position is the elastic potential energy balance point position, and at this time k1X1=k2X2. By setting the elastic potential energy balance point position, when the air deflector 10 rotates to both sides of the elastic potential energy balance point position, it can have auxiliary torques with different directions. Specifically, when the air deflector 10 rotates in the closing rotation direction, the center of gravity of the air deflector 10 rotates clockwise around the rotation center line, and the direction of the auxiliary torque provided at this time is the same as the closing rotation direction, so that the air deflector 10 is closed more tightly. When the air deflector 10 rotates in the opening rotation direction, the center of gravity of the air deflector 10 rotates counterclockwise around the rotation center line, and the direction of the auxiliary torque provided at this time is the same as the opening rotation direction, so that the air deflector 10 is opened more stably. This arrangement avoids the problem in the prior art that when the air guide plate 10 starts to rotate from the gravity conversion position, the driving unit 20 is unable to withstand the force generated at the moment of switching between gravity and the rotational force, causing the air guide plate 10 to jump during the conversion process. By providing the damping device 30, a torque force opposite to the combined force of gravity and the conversion force can be provided to the air guide plate 10 during the process of the air guide plate 10 switching from the closed state to the open state, so as to ensure that the air guide plate 10 can move smoothly.

[0040] Specifically, Figure 7 As shown, the gravity conversion position of the air deflector 10, i.e., the center of gravity of the air deflector 10, is located directly above the rotation center. When the air deflector 10 in the prior art starts to rotate from the gravity conversion position, due to the absence of the damping device 30, the air deflector 10 will suddenly be affected by the component force of its own gravity and inertia during rotation, causing the rotation speed of the air deflector 10 to accelerate first and then become uniform, causing the air deflector 10 to jump during the rotation process.

[0041] like Figure 2 and Figure 5 As shown, the damping device 30 also includes: a first connecting structure 33, the first connecting structure 33 is fixedly connected to the support portion 40; a second connecting structure 34, the second connecting structure 34 is fixedly connected to the second arm 13, and the second connecting structure 34 is hinged to the first connecting structure 33; wherein the first damping member 31 and the second damping member 32 are both connected to the first connecting structure 33, and the first damping member 31 and the second damping member 32 respectively apply torque to the second connecting structure 34.

[0042] In this embodiment, the support portion 40 and the second arm 13 can rotate relative to each other, so as to adjust the rotation angle of the wind deflector 10. The first connection structure 33 and the support portion 40 are fixedly connected, and the second connection structure 34 and the second arm 13 are fixedly connected, that is, the first connection structure 33 and the second connection structure 34 can rotate relative to each other. Specifically, when the wind deflector 10 switches between the closed state and the open state, the support portion 40 and the second arm 13 rotate together, and the support portion 40 and the second arm 13 are relatively stationary; when the wind deflector 10 is in the open state, the support portion 40 and the second arm 13 rotate relative to each other to adjust the rotation angle of the wind deflector 10. At this time, the support portion 40 does not move, and the second arm 13 drives the wind deflector 10 to rotate, that is, the first connection structure 33 does not rotate, and the second connection structure 34 rotates. The first damping member 31 and the second damping member 32 in the first connection structure 33 rotate with the second connection structure 34 to apply torque to the second connection structure 34, thereby providing auxiliary torque for the wind deflector 10 and ensuring the stability and reliability of the rotation of the wind deflector 10.

[0043] like Figure 5 As shown, the first connection structure 33 includes a box body 331 and a fixed shaft 332 disposed in the box body 331, the box body 331 and the support portion 40 are fixedly connected, and the first damping member 31 and the second damping member 32 are both disposed in the box body 331; the second connection structure 34 includes a cover body 341 and a rotating shaft 342 connected to each other, the cover body 341 and the second arm 13 are fixedly connected, the rotating shaft 342 and the fixed shaft 332 are sleeved, and the first damping member 31 and the second damping member 32 respectively apply torque to the rotating shaft 342. In this arrangement, as the air guide plate 10 rotates, the cover body 341 and the rotating shaft 342 rotate, and the auxiliary torque provided by the two damping members limits the rotation of the second connection structure 34, thereby improving the stability of adjusting the rotation of the air guide plate 10.

[0044] Specifically, the first damping member 31 and the second damping member 32 are both springs, and the first connecting structure 33 further includes a guide ring 333 disposed in the box body 331, and the first damping member 31 and the second damping member 32 are both sleeved on the guide ring 333. This arrangement prevents the first damping member 31 and the second damping member 32 from deviating, ensures that the torques provided by the first damping member 31 and the second damping member 32 are on the same plane, and ensures the reliability of the auxiliary torque provided by the damping device 30.

[0045] Furthermore, the rotating shaft 342 includes a sleeve 3421 and a baffle 3422 disposed on the sleeve 3421, the fixed shaft 332 penetrates the sleeve 3421, the guide ring 333 is coaxially disposed with the sleeve 3421, and the guide ring 333 passes through the through hole on the baffle 3422, and the ends of the first damping member 31 and the second damping member 32 are respectively abutted against the two sides of the baffle 3422. In this arrangement, the first damping member 31 or the second damping member 32 can be compressed by the rotation of the rotating shaft 342, so as to achieve the purpose of adjusting the auxiliary torque provided by the damping device 30 according to the opening angle of the air guide plate 10.

[0046] Specifically, the first connection structure 33 further includes a limiting plate 334, which is fixed on the inner wall of the box body 331. One end of the first damping member 31 away from the rotating shaft 342 abuts against one side of the limiting plate 334, and one end of the second damping member 32 away from the rotating shaft 342 abuts against the other side of the limiting plate 334. In this way, both ends of the first damping member 31 and both ends of the second damping member 32 abut against the limiting plate 334 and the baffle 3422, and the two damping members are limited and compressed by the rotatable baffle 3422 and the fixed limiting plate 334, thereby ensuring the reliability of the damping device 30.

[0047] Optionally, the guide ring 333 is connected to the limit plate 334. The first connection structure 33 further includes a buckle arranged on the box body 331, the buckle is buckled with the support part 40, and the cover body 341 is buckled with the second arm 13.

[0048] Alternatively, if Figure 7 As shown, when the air guide plate 10 is in the closed state, the angle between the baffle plate 3422 and the limiting plate 334 is 110° to 130°, for example, 120°.

[0049] like Figure 1As shown, the support part 40 includes: a connecting rod 41, which is rotatably arranged; a first rotating arm 42, one end of which is fixedly connected to one end of the connecting rod 41, and the driving part 20 is installed at the other end of the first rotating arm 42; a second rotating arm 43, one end of which is fixedly connected to the other end of the connecting rod 41, and the damping device 30 is installed at the other end of the second rotating arm 43. In this arrangement, the driving part 20 and the damping device 30 at both ends of the air deflector 10 are connected through the support part 40, the coaxial arrangement of the driving part 20 and the damping device 30 is ensured, and the reliability of the rotation of the air deflector 10 is ensured.

[0050] Optionally, the support portion 40 further includes a third rotating arm, one end of the third rotating arm is fixedly connected to the middle of the connecting rod 41, and the other end of the third rotating arm is hinged to the third arm on the air guide plate 10. The box body 331 and the second rotating arm 43 are clamped.

[0051] Another embodiment of the present invention provides an air guiding device, which is different from the above embodiment in that: the first damping member 31 and the second damping member 32 are both torsion springs.

[0052] Another embodiment of the present invention provides an air conditioner, the air conditioner includes a housing structure and the above-mentioned air guide device, the housing structure has an air outlet, and the air guide plate 10 of the air guide device is arranged at the air outlet to open or close the air outlet. Specifically, when the air guide plate 10 is in a closed state, the air guide plate 10 blocks the air outlet; when the air guide plate 10 is in an open state, the air guide plate 10 avoids the air outlet.

[0053] Optionally, when the air deflector 10 is in a closed state, under the action of the auxiliary torque of the damping device 30, the periphery of the air deflector 10 is flush with the periphery of the air outlet.

[0054] Specifically, the air conditioner further includes a driving mechanism disposed in the housing structure, and the driving mechanism is drivingly connected to the connecting rod 41 of the air guide device. In this way, the air guide plate 10 is switched between the open state and the closed state through the driving connection between the driving mechanism and the connecting rod 41. Specifically, the air guide plate 10 can be extended out of the air outlet or blocked through the swing of the connecting rod 41 and the rotating arm.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
