Therefore, this utility model is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

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

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

[0048] Shape memory alloys (SMA) are alloy materials that, when heated, completely eliminate the deformation that occurred at lower temperatures, restoring their original shape before deformation—in other words, alloys possessing a "memory" effect. There are many successful examples of their application in the aerospace field. The massive antennas on artificial satellites can be made of shape memory alloys. Before launching a satellite, the parabolic antenna is folded and installed inside the satellite. After the rocket lifts off and places the satellite into its designated orbit, simply heating it causes the folded antenna to naturally unfold and restore its parabolic shape due to its "memory" function.

[0049] Compared with the traditional air conditioner vent drive mechanism that uses an electric motor as the drive source, the air conditioner vent drive mechanism in this embodiment utilizes the temperature-driven characteristics of shape memory alloy. It can extend or shorten the SMA metal wire 3 according to the heat change when the power is on and off, thereby achieving the purpose of the SMA metal wire 3 driving the moving claw assembly to move back and forth, and thus realizing the opening or closing of the louver 13. It is not only simple in structure and easy to implement, but also has low power consumption, low noise, and small weight and size, thus improving space utilization.

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

[0051] In one feasible implementation, the movable claw assembly includes a movable claw 2. Specifically, the fixed claw 1 includes a first fixed end and a second fixed end spaced apart along a first direction x. The movable claw assembly includes a movable claw 2, which includes a first movable end and a second movable end spaced apart along the first direction x. The first fixed end is fixed to the air conditioner housing, the second fixed end is connected to one end of the SMA metal wire 3, and the first movable end is connected to the other end of the SMA metal wire 3. The first movable end is also connected to a transmission mechanism, thereby connecting to the louver 13. When the SMA metal wire 3 is energized, it shortens, pulling the movable claw assembly in the first direction x. The movable claw assembly pulls the transmission mechanism in the first direction x, and the transmission mechanism drives the louver 13 to open. When the SMA metal wire 3 is de-energized, it extends, pushing the movable claw assembly in the second direction y. The movable claw assembly 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 movable claw assembly includes at least two movable claws 2. Specifically, the fixed claw 1 includes a first fixed end and a second fixed end spaced apart, and the movable claw assembly includes at least two movable claws 2. Each movable claw 2 includes a first movable end and a second movable end spaced apart. At least two SMA metal wires 3 are also provided, and the number of movable claws 2 and SMA metal wires 3 are the same. The fixed claw 1 and all movable claws 2 are stacked sequentially. The first fixed end is fixed to the air conditioner housing. The second fixed end is connected to the first movable end of the movable claw 2 adjacent to the fixed claw 1 through an SMA metal wire 3. The second movable end of the movable claw 2 adjacent to the fixed claw 1 is connected to the first movable end of the adjacent movable claw 2 through another SMA metal wire 3; and so on, until it is connected to the first movable end of the movable claw 2 located on the outermost side along the stacking direction. Along the stacking direction, the first movable end of the outermost movable claw 2 is also connected to the louver 13 of the air conditioner outlet. 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 claw 1 and the movable claw 2 are plate-shaped structures. The layered structure makes the overall structure more compact and occupies less space. The layered structure allows the deformation of each SMA metal wire 3 to be sequentially superimposed, thereby causing the displacement distances of all movable claws 2 to be sequentially superimposed, achieving the driving of the louver 13 by the movable claw assembly. In this embodiment, as... Figures 1 to 4 As shown, the movable claw assembly includes six movable claws 2, named first movable claw, second movable claw, third movable claw, fourth movable claw, fifth movable claw, and sixth movable claw, respectively. The first movable claw is adjacent to the fixed claw 1, and the first, second, third, fourth, fifth, and sixth movable claws are stacked sequentially along the stacking direction. Six SMA metal wires 3 are also provided, named first SMA metal wire, second SMA metal wire, third SMA metal wire, fourth SMA metal wire, fifth SMA metal wire, and sixth SMA metal wire, respectively. The first SMA metal wire connects the fixed claw 1 and the first movable claw. The fixed claw 1 and the six movable claws 2 are stacked sequentially, with the fixed claw 1 located at the bottom and fixedly connected to the air conditioner housing.

[0054] The first fixed end of the fixed claw 1 is fixed to the air conditioner housing. The second fixed end is connected to the first moving end of the first moving claw via a first SMA metal wire. The second moving end of the first moving claw is connected to the first moving end of the second moving claw via a second SMA metal wire. The second moving end of the second moving claw is connected to the first moving end of the third moving claw via a third SMA metal wire. The second moving end of the third moving claw is connected to the first moving end of the fourth moving claw via a fourth SMA metal wire. The second moving end of the fourth moving claw is connected to the first moving end of the fifth moving claw via a fifth SMA metal wire. The second moving end of the fifth moving claw is connected to the first moving end of the sixth moving claw via a sixth SMA metal wire. The first moving end of the sixth moving claw is connected to the transmission mechanism. The transmission mechanism is connected to the louver 13 of the air conditioner outlet. The second moving end of the sixth moving claw is free.

[0055] When all SMA wires 3 are energized, all SMA wires 3 deform. Assuming that the deformation of all SMA wires 3 produces a displacement distance of 1 cm along the first direction x, the first SMA wire pulls the first moving claw to move 1 cm in the first direction x. The first moving claw, through the second SMA wire, pulls the second moving claw to move 1 cm in the first direction x. This, combined with the 1 cm displacement distance produced by the deformation of the second SMA wire along the first direction x, results in a total movement of 2 cm in the second moving claw along the first direction x. This process continues, with the 1 cm displacement distance produced by the deformation of the SMA wires 3 and the 1 cm displacement distance produced by the moving claws 2 in the first direction x being cumulatively added 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 louvers 13 to open. When all SMA wires 3 are de-energized, all SMA wires 3 return to their initial state, and all moving claws 2 move back to the second direction y, driving the louvers 13 to close.

[0056] When only the first SMA metal wire is energized, only the first SMA metal wire deforms. Assuming the deformation of the first SMA metal wire generates a displacement distance of 1 cm along the first direction, the first SMA metal wire pulls the first moving claw to move 1 cm in the first direction x. The first moving claw then pulls the second moving claw to move 1 cm in the first direction x via the second SMA metal wire, and so on, with the 1 cm displacement distance being transmitted sequentially along the stacking direction until the fifth moving claw pulls the sixth moving claw to move 1 cm in the first direction x via the sixth SMA metal wire. The sixth moving claw then pulls the transmission mechanism to move 1 cm in the first direction x, and the transmission mechanism drives the louver 13 to open. When the first SMA metal wire is de-energized, it returns to its initial state, and the first moving claw moves 1 cm in the second direction y, and so on, until all the moving claws 2 reset, driving the louver 13 to close.

[0057] The opening state of the louver 13 when all SMA metal wires 3 are energized is named the first opening state, and the opening state of the louver 13 when only the first SMA metal wire is energized is named the second opening state. The opening degree of the louver 13 in the first opening state is greater than the opening degree of the louver 13 in the second opening state.

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

[0059] Whether the movable claw assembly includes one movable claw 2 or at least two movable claws 2, it can drive the louver 13. When the movable claw assembly includes at least two movable claws 2, the deformation of at least two SMA metal wires 3 will be superimposed. Therefore, the moving distance of the movable claw 2 will be greater than that of a single movable claw 2, resulting in a more significant driving effect on the louver 13 and a greater degree of opening and closing of the louver 13. In actual design, the appropriate choice can be made based on the specific circumstances.

[0060] The fixed claw 1 and all the movable claws 2 are staggered sequentially in the stacking direction, with the outermost movable claw 2 having the smallest distance from the side where the louvers 13 of the air conditioner outlet are located. This structural arrangement minimizes the driving distance of the movable claw group to the louvers 13, resulting in a direct and effective driving action. In this embodiment, the first movable claw has the largest distance from the side where the louvers 13 are located, while the sixth movable claw has the smallest distance.

[0061] To achieve the fixation of the SMA metal wire 3 to the jaws, such as Figure 5 As shown, the second fixed end, the first moving end and the second moving end connected to the SMA metal wire 3 are all provided with a fixing part 4, which is used to fix the end of the SMA metal wire 3.

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

[0063] In this embodiment, such as Figure 6As shown, the air conditioner outlet drive mechanism also includes an anti-friction part 5. The anti-friction part 5 is sandwiched between the fixed claw 1 and its adjacent movable claw 2, as well as between two adjacent movable claws 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, friction between adjacent claws can be avoided, and the structural strength of the claws can be improved, thereby enhancing the operational stability and reliability of the drive mechanism. Anti-friction parts 5 are provided between the fixed claw 1 and the first movable claw, between the first and second movable claws, between the second and third movable claws, between the third and fourth movable claws, between the fourth and fifth movable claws, and between the fifth and sixth movable claws. The anti-friction part 5 can be, but is not limited to, a plate-like structure, and its shape is adapted to the fixed claw 1 and the movable claw 2, which helps to improve the integrity and compactness of the stacked structure.

[0064] Along the stacking direction, the anti-friction parts 5 are all fixedly connected to the movable claws 2 that are away from the fixed claw 1. Specifically, the anti-friction part 5 between the fixed claw 1 and the first movable claw is fixedly connected to the first movable claw; the anti-friction part 5 between the first and second movable claws is fixedly connected to the second movable claw; the anti-friction part 5 between the second and third movable claws is fixedly connected to the third movable claw; the anti-friction part 5 between the third and fourth movable claws is fixedly connected to the fourth movable claw; the anti-friction part 5 between the fourth and fifth movable claws is fixedly connected to the fifth movable claw; and the anti-friction part 5 between the fifth and sixth movable claws is fixedly connected to the sixth movable claw. The size of the anti-friction part 5 is the same as the size of the movable claw 2 connected to it, thereby improving the aesthetics and overall integrity.

[0065] To connect the drive mechanism to the air conditioner housing, both the fixed claw 1 and the movable claw 2 are provided with strip-shaped clearance holes 6. All clearance holes 6 are interconnected, and the connector 7 passes through all the clearance holes 6 in sequence to connect with the air conditioner housing. At the same time, the connector 7 also limits the movement of the movable 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 movable claw assembly, 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 louvers 13. In this embodiment, one end of the drive belt 8 is connected to the sixth movable claw, and 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 movable claw assembly to reset via the drive belt 8. The drive belt 8 transmits power to the drive mechanism via the cam 9. When the cam 9 rotates, it drives the louvers 13 to open or close. In this embodiment, ... Figure 3 Taking the example shown, the movement of the air conditioner vent structure is described. When the drive belt 8 moves along the first direction x, the cam 9 rotates clockwise, and the louver 13 rotates clockwise. When the drive belt 8 moves along the second direction y, the cam 9 rotates counterclockwise, and the louver 13 rotates counterclockwise. The elastic reset element 10 can be, but is not limited to, a tension spring.

[0067] To enable the transmission mechanism to drive the louvers 13, the transmission mechanism also 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 louvers 13. All blades of the louvers 13 are spaced apart along the length of the linkage rod 12 and are rotatably connected to the linkage rod 12. All blades of the louvers 13 are rotatably connected to the air conditioner housing. The connection points between the blades and the linkage rod 12 and between the blades and the air conditioner housing are spaced apart. In this structure, the cam 9 drives the transmission rod 11 to rotate, the transmission rod 11 drives the blade connected to it to rotate, and the blade drives the other blades to rotate synchronously through the linkage rod 12.

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

[0069] like Figure 2 As shown, when the SMA metal wire 3 is energized, the sixth moving claw moves along the first direction x, and 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 through the transmission rod 11 and the linkage rod 12 to open the air conditioner outlet. When the SMA metal 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, and 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 through the transmission rod 11 and the linkage rod 12 to close the air conditioner outlet.
