It should be added that, in an actual structure, when the air deflector 300 moves to the limit position, the motor crank 500 continues to transmit torque to the air guide crank 400 until the torque reaches the rotation blocking torque, which may cause the connection between the air guide crank 400 and the air deflector 300 to break; in order to enable the air guide crank 400 to have certain elasticity and deformation capacity, the air guide crank 400 is particularly provided with a first connecting part 410, a second connecting part 430 and at least one energy absorbing part 440, when the air guide plate 300 does not move to a limit position, the first connecting part 410 is linked with the second connecting part 430, when the air guide plate 300 moves to the limit position, the motor 200 drives the second connecting part 430 to move through the motor crank 500, and the first connecting part 410 is kept still, in the process, the energy absorbing part 440 absorbs a part of torque transmitted to the first connecting part 410 by the second connecting part 430, the torque borne by the connecting part of the first connecting part 410 and the air guide plate 300 is reduced, and the connecting part is prevented from being broken.

The air guide crank 400 and the motor crank 500 are made of plastic parts, preferably, the air guide crank 400 and the motor crank 500 are made of POM (polyoxymethylene) materials, and at the moment, deformation can be effectively absorbed through energy absorption design of the air guide crank 400, so that jamming is avoided, and smoothness of movement is guaranteed.

As shown in fig. 1, 2, and 4-6, the second connecting portion 430 is configured as a ring gear structure, the first connecting portion 410 is located in the second connecting portion 430, and the first connecting portion 410 is provided with a transmission shaft 420 in linkage connection with the air deflector 300, and the transmission shaft 420 is coaxially arranged with the first connecting portion 410.

The motor crank 500 includes a gear 510 and a connecting shaft 520, the connecting shaft 520 is located at the center of the gear 510, the connecting shaft 520 is integrally connected with the gear 510, the connecting shaft 520 is connected with the motor 200, and the gear 510 is engaged with the second connecting portion 430.

The air guide crank 400 and the motor crank 500 are driven by gear engagement, specifically, the first connecting portion 410 can rotate by using the transmission shaft 420 as an axis, the gear 510 can rotate by using the connecting shaft 520 as an axis, the second connecting portion 430 is engaged with the gear 510, when the motor 200 rotates, the gear 510 can be driven by the connecting shaft 520 to rotate, and then the second connecting portion 430 is driven to rotate, the first connecting portion 410 is linked with the first connecting portion 410 by the energy absorbing portion 440, and the first connecting portion 410 drives the air guide plate 300 to rotate upwards or downwards by using the transmission shaft 420, so that the purpose of adjusting the air guide plate 300 is achieved.

It should be noted here that the energy absorbing portion 440 has an elastic deformation capability, and when the second connecting portion 430 and the gear 510 are squeezed, the energy absorbing portion 440 is deformed, so that the connection between the transmission shaft 420 and the air guiding plate 300 is not broken on the basis of avoiding jamming.

Optionally, for different motors 200, different requirements can be met by adjusting the gear transmission ratio between the motor crank 500 and the air guide crank 400.

As shown in fig. 1, 2, and 4-6, in the structural layout of the air outlet, in particular, the motor 200, the air guide crank 400, and the motor crank 500 are disposed on a side wall of the housing 100, the outer side wall of the housing 100 is provided with the motor fixing seat 120, the motor 200 is mounted on the motor fixing seat 120, and both the motor crank 500 and the air guide crank 400 are located on the outer side wall of the housing 100.

Preferably, the air guiding plate 300 is provided with a rotating shaft 310, the rotating shaft 310 is connected to the inner side wall of the casing 100, the air guiding plate 300 can rotate around the rotating shaft 310, and the transmission shaft 420 penetrates through the side wall of the casing 100 and is fixedly connected to the rotating shaft 310. Specifically, the driving shaft 420 is inserted into the rotation shaft 310 and coupled together by a snap-fit, so that the driving shaft 420 can transmit the torque of the motor 200 to the wind guide plate 300.

As shown in fig. 1 and 4 to 6, the number of the energy absorbing portions 440 is at least two, and each of the energy absorbing portions 440 is radially distributed between the first connecting portion 410 and the second connecting portion 430 around the rotation axis of the air guide crank 400. The plurality of energy absorbing parts 440 can better connect the first connecting part 410 and the second connecting part 430 together, and keep the two in a linkage state when the air deflector 300 is not in the limit position.

The connection between the energy absorbing portion 440 and the first connection portion 410 and/or the connection between the energy absorbing portion and the second connection portion 430 are formed in an arc-shaped structure.

Preferably, in order to allow the energy absorbing portion 440 to be deformed better and absorb torque, the energy absorbing portion 440 may be shaped like an S, two ends of the energy absorbing portion 440 are connected to the first connecting portion 410 and the second connecting portion 430 through an arc structure, and since the air deflector 300 has an upper limit position and a lower limit position, when the air deflector 300 is located at the upper limit position, the arc structure at one end of the energy absorbing portion 440 is deformed to absorb torque, and when the air deflector 300 is located at the lower limit position, the arc structure at the other end of the energy absorbing portion 440 is deformed to absorb torque.

Similarly, if the air deflector 300 has only one-sided rotation blockage, the energy absorbing portion 440 may preferably have an arc-shaped connection with the first connection portion 410 or an arc-shaped connection with the second connection portion 430.

In another embodiment, the energy absorbing part comprises at least one bending part with a preset bending degree, and the bending degree of the bending part is changed along with the change of the dislocation angle of the first connecting part and the second connecting part; in this embodiment, the misalignment angle between the first connecting portion and the second connecting portion is zero when the wind guide crank is not subjected to an external force normally, and when the first connecting portion and the second connecting portion receive the external force respectively, the first connecting portion and the second connecting portion form a misalignment relationship, and the bending degree of the bending portion changes with the change of the misalignment angle between the first connecting portion and the second connecting portion; regardless of the clockwise or counterclockwise misalignment, the greater the misalignment angle between the first and second connecting portions, the greater the change in the degree of curvature of the curved portion.

As shown in fig. 1 to 6, when the air deflector 300 reaches the upper limit or the lower limit, the motor crank 500 rotates and contacts with the limit of the motor fixing seat 120 to stop rotating, and this part of the force is transmitted to the motor 200 to generate a torque, and when this part of the torque reaches the locked-rotor torque requirement of the motor 200, the motor 200 stops rotating, which is called locked-rotor.

Theoretically, when the motor 200 is locked, the air deflector 300 just reaches the limit position. In the practical process, because the locked-rotor torque of the motor 200 is too large, the torque is transmitted to the air guide crank 400 through the motor crank 500, and because the air guide crank 400 is in a stagnation state, the torque is generated at the buckling connection part of the air guide crank 400 and the rotating shaft 310 at the end part of the air deflector 300, so that the connection part of the transmission shaft 420 and the rotating shaft 310 is easy to break; the first connecting portion 410 and the second connecting portion 430 are connected in a linkage manner through the energy absorbing portion 440, and the energy absorbing portion 440 can deform to absorb a part of torque transmitted between the first connecting portion 410 and the second connecting portion 430, so that the fastening position where the transmission shaft 420 of the air guide crank 400 is connected with the rotating shaft 310 of the air guide plate 300 cannot be broken in the rotation blocking process, and meanwhile, the air guide plate 300 is attached to the casing 100 more tightly.
