[0046] This embodiment discloses an air outlet structure of an air conditioner, as Figure 1 shown. The air outlet structure of the air conditioner includes an air outlet driving mechanism of the air conditioner, a transmission mechanism, and louvers 13. One end of the transmission mechanism is connected to the air outlet driving mechanism of the air conditioner, the other end of the transmission mechanism is connected to the louvers 13, and the louvers 13 are rotatably connected to the air conditioner housing. The air outlet driving mechanism of the air conditioner drives the louvers 13 to rotate relative to the air conditioner housing through the transmission mechanism, realizing the reciprocating swing of the louvers 13, and thus realizing the opening or closing of the air outlet by the louvers 13.

[0047] As Figures 2 to 4 shown, the air outlet driving mechanism of the air conditioner disclosed in this embodiment includes a fixed claw 1, a moving claw group, and an SMA wire 3. The fixed claw 1 is fixed to the air conditioner housing. One end of the moving claw group is connected to the fixed claw 1 through the SMA wire 3, and the other end of the moving claw group is connected to the louvers 13 of the air outlet through the transmission mechanism. In this structure, when the SMA wire 3 is energized, it pulls the moving claw group to move in the first direction x, and the moving claw group drives the louvers 13 to open; when the SMA wire 3 is de-energized, the moving claw group moves in the second direction y, and the moving claw group drives the louvers 13 to close. The first direction x and the second direction y are opposite to each other.

[0048] Shape Memory Alloys (SMA) is an alloy material that can completely eliminate the deformation that occurs at a lower temperature and restore its original shape before deformation after heating up, that is, an alloy with a "memory" effect. There are many successful examples of its application in the aerospace field. The huge antenna on the artificial satellite can be made of memory alloy. Before launching the artificial satellite, the parabolic antenna is folded and installed in the satellite body. After the rocket lifts off and sends the artificial satellite to the predetermined orbit, only by heating, the folded satellite antenna will naturally unfold due to its "memory" function and restore the parabolic shape.

[0049] Compared with the traditional air-conditioning air outlet driving mechanism that uses a motor as the driving source, the air-conditioning air outlet driving mechanism in this embodiment utilizes the temperature driving characteristic of the shape memory alloy. According to the heat change during power-on and power-off, the elongation or shortening of the SMA wire 3 can be realized, so as to realize the reciprocating movement of the moving claw group driven by the SMA wire 3, and then realize the opening or closing of the louver 13. It not only has a simple structure and is easy to implement, but also has low power consumption, low noise, small weight and volume, and improves the space utilization rate.

[0050] It should be noted that the fixed claw 1 can drive the louver 13 whether it is located above or below the moving claw group. In this embodiment, the fixed claw 1 is located below the moving claw group.

[0051] In a feasible implementation, the moving claw group includes a moving claw 2. Specifically, the fixed claw 1 includes a first fixed end and a second fixed end spaced along the first direction x. The moving claw group includes a moving claw 2. The moving claw 2 includes a first moving end and a second moving end spaced along the first direction x. The first fixed end is fixed to the air-conditioning housing, the second fixed end is connected to one end of the SMA wire 3, the first moving end is connected to the other end of the SMA wire 3, and the first moving end is also connected to the transmission mechanism and thus connected to the louver 13. When the SMA wire 3 is powered on, the SMA wire 3 shortens and pulls the moving claw group to move in the first direction x. The moving claw group pulls the transmission mechanism in the first direction x, and the transmission mechanism drives the louver 13 to open. When the SMA wire 3 is powered off, the SMA wire 3 elongates and pushes the moving claw group to move in the second direction y. The moving claw group pushes the transmission mechanism in the second direction y, and the transmission mechanism drives the louver 13 to close.

[0052] In another feasible implementation, the moving claw group includes at least two moving claws 2. Specifically, the fixed claw 1 includes a first fixed end and a second fixed end arranged at intervals. The moving claw group includes at least two moving claws 2. Each moving claw 2 includes a first moving end and a second moving end arranged at intervals. There are also at least two SMA wires 3, and the number of moving claws 2 is the same as that of the SMA wires 3. The fixed claw 1 and all the moving claws 2 are stacked in sequence. The first fixed end is fixed to the air-conditioning housing, and the second fixed end is connected to the first moving end of the moving claw 2 adjacent to the fixed claw 1 through an SMA wire 3. The second moving end of the moving claw 2 adjacent to the fixed claw 1 is connected to the first moving end of the adjacent moving claw 2 through another SMA wire 3; and so on until it is connected to the first moving end of the outermost moving claw 2 in the stacking direction. In the stacking direction, the first moving end of the outermost moving claw 2 is also connected to the louver 13 of the air-conditioning air outlet, and the stacking direction is perpendicular to the direction where the first direction x and the second direction y are located.

[0053] In this embodiment, both the fixed jaw 1 and the movable jaw 2 are plate-like structures. The use of a stacked structure makes the overall structure more compact and occupies less space. The stacked structure enables the deformations of each SMA wire 3 to be sequentially superimposed, so that the displacement distances of all the movable jaws 2 are sequentially superimposed, realizing the driving of the movable jaw group on the louver 13. In this embodiment, as Figures 1 to 4 shown, the movable jaw group includes six movable jaws 2, which are respectively named the first movable jaw, the second movable jaw, the third movable jaw, the fourth movable jaw, the fifth movable jaw, and the sixth movable jaw. Among them, the first movable jaw is adjacent to the fixed jaw 1, and the first movable jaw, the second movable jaw, the third movable jaw, the fourth movable jaw, the fifth movable jaw, and the sixth movable jaw are sequentially stacked in the stacking direction; there are also six SMA wires 3, which are respectively named the first SMA wire, the second SMA wire, the third SMA wire, the fourth SMA wire, the fifth SMA wire, and the sixth SMA wire. Among them, the first SMA wire is connected between the fixed jaw 1 and the first movable jaw. The fixed jaw 1 and the six movable jaws 2 are sequentially stacked, and the fixed jaw 1 is located at the bottom and fixedly connected to the air conditioner housing.

[0054] The first fixed end of the fixed jaw 1 is fixed to the air conditioner housing, and the second fixed end is connected to the first movable end of the first movable jaw through the first SMA wire. The second movable end of the first movable jaw is connected to the first movable end of the second movable jaw through the second SMA wire. The second movable end of the second movable jaw is connected to the first movable end of the third movable jaw through the third SMA wire. The second movable end of the third movable jaw is connected to the first movable end of the fourth movable jaw through the fourth SMA wire. The second movable end of the fourth movable jaw is connected to the first movable end of the fifth movable jaw through the fifth SMA wire. The second movable end of the fifth movable jaw is connected to the first movable end of the sixth movable jaw through the sixth SMA wire. The first movable end of the sixth movable jaw is connected to the transmission mechanism, and the transmission mechanism is connected to the louver 13 of the air conditioner air outlet. The second movable end of the sixth movable jaw is free.

[0055] When all the SMA wires 3 are energized, all the SMA wires 3 deform. Assuming that the deformation of all the SMA wires 3 can generate a displacement distance of 1 cm along the first direction x, then the first SMA wire pulls the first moving claw to move 1 cm in the first direction x. The first moving claw pulls the second moving claw to move 1 cm in the first direction x through the second SMA wire. Adding the 1 cm displacement distance generated by the deformation of the second SMA wire along the first direction x, the second moving claw moves a total of 2 cm in the first direction x. And so on, the 1 cm displacement distance generated by the deformation of the SMA wire 3 in the first direction x and the 1 cm displacement distance generated by the moving claw 2 in the first direction x are stacked layer by layer until the sixth moving claw moves 6 cm in the first direction x. Therefore, the sixth moving claw pulls the transmission mechanism to move 6 cm in the first direction x, and the transmission mechanism drives the shutter 13 to open. When all the SMA wires 3 are de-energized, all the SMA wires 3 return to their initial states, and all the moving claws 2 move in the second direction y to reset, driving the shutter 13 to close.

[0056] When only the first SMA wire is energized, only the first SMA wire deforms. Assuming that the deformation of the first SMA wire can generate a displacement distance of 1 cm along the first direction, then the first SMA wire pulls the first moving claw to move 1 cm in the first direction x. The first moving claw pulls the second moving claw to move 1 cm in the first direction x through the second SMA wire. And so on, the 1 cm displacement distance is transmitted in sequence along the stacking direction until the fifth moving claw pulls the sixth moving claw to move 1 cm in the first direction x through the sixth SMA wire. The sixth moving claw pulls the transmission mechanism to move 1 cm in the first direction x, and the transmission mechanism drives the shutter 13 to open. When the first SMA wire is de-energized, the first SMA wire returns to its initial state, and the first moving claw moves 1 cm in the second direction y. And so on, all the moving claws 2 are reset, driving the shutter 13 to close.

[0057] Name the open state of the shutter 13 when all the SMA wires 3 are energized as the first open state, and name the open state of the shutter 13 when only the first SMA wire is energized as the second open state. The opening degree of the shutter 13 in the first open state is greater than that in the second open state.

[0058] Of course, the number of the moving claws 2 and the number of the SMA wires 3 are not limited to six in this embodiment and can be designed according to the actual situation.

[0059] Whether the movable jaw group includes one movable jaw 2 or at least two movable jaws 2, it can drive the louver 13. When the movable jaw group includes at least two movable jaws 2, since the deformations of at least two SMA wires 3 will be superimposed, the moving distance of the movable jaw 2 will be greater than that of only one movable jaw 2, the driving effect on the louver 13 is more obvious, and the opening and closing degree of the louver 13 is greater. In actual design, it can be selected according to the actual situation.

[0060] The fixed jaw 1 and all movable jaws 2 are arranged in sequence with a dislocation in the stacking direction, and the distance from the outermost movable jaw 2 to the side where the louver 13 of the air-conditioning air outlet is located is the smallest. This structural setting makes the driving distance of the movable jaw group to the louver 13 the shortest, and the driving effect is direct and effective. In this embodiment, the distance from the first movable jaw to the side where the louver 13 is located is the largest, and the distance from the sixth movable jaw to the side where the louver 13 is located is the smallest.

[0061] To fix the SMA wire 3 to the jaw, as Figure 5 shown, the second fixed end, the first movable end and the second movable end connected to the SMA wire 3 are all provided with fixing parts 4, and the fixing parts 4 are used to fix the end of the SMA wire 3.

[0062] Optionally, the fixing part 4 is a bending structure formed on the edges of the fixed jaw 1 and the movable jaw 2, and the end of the SMA wire 3 is clamped and fixed in the bending structure. The bending structure is a structure formed by bending the flanging extending from the edge of the jaw towards the jaw body. Of course, the structure of the fixing part 4 is not limited to this, and it can also be other structures that can fix the wire, which will not be listed one by one here.

[0063] In this embodiment, as Figure 6 shown, the air-conditioning air outlet driving mechanism further includes an anti-friction part 5. The anti-friction part 5 is clamped between the fixed jaw 1 and the adjacent movable jaw 2, and between two adjacent movable jaws 2. The anti-friction part 5 is fixedly connected to one of them and slidably connected to the other. By setting the anti-friction part 5, on the one hand, it can prevent the adjacent two jaws from rubbing against each other, and on the other hand, it can also improve the structural strength of the jaws and improve the operation stability and reliability of the driving mechanism. Anti-friction parts 5 are provided between the fixed jaw 1 and the first movable jaw, between the first movable jaw and the second movable jaw, between the second movable jaw and the third movable jaw, between the third movable jaw and the fourth movable jaw, between the fourth movable jaw and the fifth movable jaw, and between the fifth movable jaw and the sixth movable jaw. The anti-friction part 5 can be but is not limited to a plate-like structure, and the shape of the anti-friction part 5 is adapted to the fixed jaw 1 and the movable jaw 2, which is beneficial to improving the integrity and compactness of the stacked structure.

[0064] In the stacking direction, the anti-friction part 5 is fixedly connected to the moving claw 2 away from the fixed claw 1. Specifically, the anti-friction part 5 between the fixed claw 1 and the first moving claw is fixedly connected to the first moving claw, the anti-friction part 5 between the first moving claw and the second moving claw is fixedly connected to the second moving claw, the anti-friction part 5 between the second moving claw and the third moving claw is fixedly connected to the third moving claw, the anti-friction part 5 between the third moving claw and the fourth moving claw is fixedly connected to the fourth moving claw, the anti-friction part 5 between the fourth moving claw and the fifth moving claw is fixedly connected to the fifth moving claw, and the anti-friction part 5 between the fifth moving claw and the sixth moving claw is fixedly connected to the sixth moving claw. The outer shape and size of the anti-friction part 5 are the same as those of the moving claw 2 connected thereto, thereby improving the appearance aesthetics and integrity.

[0065] To realize the connection between the driving mechanism and the air conditioner housing, strip-shaped avoidance holes 6 are formed in both the fixed claw 1 and the moving claw 2, and all the avoidance holes 6 are communicated. The connecting piece 7 sequentially passes through all the avoidance holes 6 and is connected to the air conditioner housing. At the same time, the connecting piece 7 also has a limiting effect on the movement of the moving claw 2.

[0066] The transmission mechanism in this embodiment includes a drive belt 8, an elastic reset member 10, and a cam 9. One end of the drive belt 8 is connected to the moving claw group, one end of the elastic reset member 10 is connected to the other end of the drive belt 8, and the other end of the elastic reset member 10 is connected to the air conditioner housing; the cam 9 is rotatably connected to the air conditioner housing, one end of the cam 9 is connected to the drive belt 8, and the other end is connected to the louver 13. In this embodiment, one end of the drive belt 8 is connected to the sixth moving claw, the other end is connected to the elastic reset member 10, the cam 9 is connected to the middle of the drive belt 8, the elastic reset member 10 provides a restoring force for the reset of the moving claw group through the drive belt 8, the drive belt 8 transmits the power of the drive mechanism through the cam 9, and when the cam 9 rotates, the louver 13 can be driven to open or close. In this embodiment, taking the figure shown as an example, the movement of the air conditioner air outlet structure is described. When the drive belt 8 moves in the first direction x, the cam 9 rotates clockwise, and the louver 13 rotates clockwise. When the drive belt 8 moves in the second direction y, the cam 9 rotates counterclockwise, and the louver 13 rotates counterclockwise. The elastic reset member 10 can be, but is not limited to, a tension spring.

[0067] To achieve the drive of the transmission mechanism for the louver 13, the transmission mechanism further includes a transmission rod 11 and a linkage rod 12. One end of the transmission rod 11 is rotatably connected to the cam 9, and the other end of the transmission rod 11 is rotatably connected to one blade of the louver 13. All the blades of the louver 13 are arranged at intervals along the length direction of the linkage rod 12 and are respectively rotatably connected to the linkage rod 12. All the blades of the louver 13 are respectively rotatably connected to the air conditioner housing, and the connection points between the blades and the linkage rod 12 and the connection points between the blades and the air conditioner housing are arranged at intervals. In this structure, the cam 9 drives the transmission rod 11 to rotate, and the transmission rod 11 drives the connected blade to rotate. This blade drives the remaining blades to rotate synchronously through the linkage rod 12.

[0068] The movement mode of the air conditioner air outlet structure provided in this embodiment will be described below.

[0069] As Figure 2 shown, when the SMA wire 3 is energized, the sixth moving claw moves along the first direction x. The sixth moving claw pulls the drive belt 8 to move along the first direction x. The drive belt 8 drives the cam 9 to rotate clockwise. The cam 9 drives all the blades of the louver 13 to rotate clockwise around the connection point with the air conditioner housing to open the air conditioner outlet through the transmission rod 11 and the linkage rod 12. When the SMA wire 3 is de-energized, the elastic reset member 10 resets the moving claw group, that is, the sixth moving claw moves along the second direction y. The elastic reset member 10 pulls the drive belt 8 to move along the second direction y. The drive belt 8 drives the cam 9 to rotate counterclockwise. The cam 9 drives all the blades of the louver 13 to rotate counterclockwise around the connection point with the air conditioner housing to close the air conditioner outlet through the transmission rod 11 and the linkage rod 12.

[0070] This embodiment also provides an air conditioner, which includes the above-mentioned air conditioner air outlet structure. Thus, the technical advantages and effects that this air conditioner can achieve also include the technical advantages and effects that the aforementioned air conditioner air outlet structure can achieve, which will not be elaborated here.

[0071] Obviously, the above is only the preferred embodiment of the present invention and the applied technical principle.
