[0027] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] See also Figures 1 to 6 The utility model provides a swing blade mechanism for installation on a housing 1, wherein the housing 1 is provided with an air outlet 2 in the length direction, and is characterized in that the swing blade mechanism 4 comprises:

[0029] A bracket 3, arranged at the air outlet 2;

[0030] A plurality of swing blades 4 are arranged at intervals along the length direction of the bracket 3, each of the swing blades 4 is rotatably matched with the bracket 3, and has a connecting protrusion 401 protruding outward;

[0031] The driving structure includes a movably connected connecting rod 5 and a driving block 6, and a gear 7 that can rotate forward and reverse. The connecting protrusion 401 is rotatably connected to the connecting rod 5. The driving block 6 is provided with a rack 601 meshing with the gear 7, so that when the gear 7 rotates forward and reversely, the connecting rod 5 can be linked to move back and forth through the driving block 6 to make the pendulum 4 swing back and forth.

[0032] In this embodiment, the bracket 3 is used as a supporting component of the swing blade 4 mechanism and is installed at the air outlet 2 of the shell 1, ensuring that the swing blade 4 mechanism is firmly installed. A plurality of swing blades 4 are arranged at intervals along the length direction of the bracket 3. Each swing blade 4 rotates with the bracket 3 so that the swing blade 4 can cover the entire air outlet 2, thereby achieving effective adjustment of the airflow direction. The swing blades 4 are arranged at intervals along the length direction of the bracket 3 to ensure uniform dispersion of the airflow. At the same time, each swing blade 4 can rotate independently, increasing the flexibility of adjusting the air outlet direction. The swing blades 4 protrude outward. A connecting protrusion 401 is provided to connect with the connecting rod 5 in the driving structure to realize power transmission. The driving structure includes a connecting rod 5, a driving block 6 and a gear 7 that can rotate forward and reverse. The connecting protrusion 401 of the connecting rod 5 and the swing blade 4 is movably connected, so that power can be directly transmitted to the swing blade 4 through the connecting rod 5 to drive it to move. The rack 601 on the driving block 6 is meshed with the gear 7. When the gear 7 rotates forward or reversely, it will drive the rack 601 to move left and right, thereby linking the connecting rod 5 to slide up and down, and enable all the swing blades 4 to swing back and forth synchronously. The forward and reverse function of 7 enables the swing blade 4 to swing left or right as needed, so as to achieve left-right adjustment of the air flow direction, and the swing blades 4 are driven to swing left and right by moving the driving block 6 left and right and sliding the linkage connecting rod 5 up and down, thereby reducing the movement path of the swing blade 4 mechanism as a whole; compared with the prior art, the swing blade 4 connecting rod 5 and the plurality of swing blades 4 are arranged in a length direction of the air outlet 2 of the indoor unit of the air conditioner, and the swing blade 4 connecting rod 5 can be translated left and right, and the plurality of swing blades 4 are arranged on the swing blade 4 connecting rod 5 at intervals along the extension direction of the swing blade 4 connecting rod 5, and the motor 12 drives the swing blade 4 to swing left and right. One of the swing blades 4 is driven to swing left and right, and then all the swing blades 4 are driven to swing left and right synchronously through the swing blade 4 connecting rod 5, so as to realize the left and right swing wind mode. This scheme adopts pure rotation connection, and needs motor 12 to drive the swing blade 4 connecting rod 5 to rotate one circle. The torque requirement of the swing blade 4 motor 12 is large, and the energy consumption increases accordingly. The utility model reduces the rotation amplitude and sliding amplitude of the mechanism, so that the action torque of the swing blade 4 mechanism is reduced, and the output force of the motor 12 can be reduced. Under the same swing blade 4 mechanism, a motor 12 with smaller torque can be used, and the sliding is smoother and less prone to jamming.

[0033] The bracket 3 is provided with a plurality of first positioning holes 301 at intervals along the length direction thereof. The plurality of first positioning holes 301 are provided in one-to-one correspondence with the plurality of swing blades 4 , and each of the swing blades 4 is rotatably disposed in each of the first positioning holes 301 .

[0034] In this embodiment, a plurality of first positioning holes 301 are arranged at intervals along the length direction of the bracket 3, which helps to accurately position each swing blade 4 on the bracket 3, and is convenient for installation and maintenance. Each swing blade 4 has its own exclusive installation position, which ensures alignment and stability during assembly. Each first positioning hole 301 corresponds to a swing blade 4, which ensures the uniformity and accuracy of airflow control, simplifies the assembly process, and also facilitates the subsequent replacement of any damaged swing blade 4. Each swing blade 4 is rotatably arranged in the first positioning hole 301, so that the swing blade 4 can rotate freely around its own axis to achieve airflow direction adjustment. Further, the swing blade 4 includes a blade and a connecting column 402 connected in sequence, and the connecting protrusion 401 is formed on the blade, and the connecting column 402 is rotatably arranged in the first positioning hole 301; the swing blade 4 includes a blade and a connecting column 402 connected in sequence, and the connecting protrusion 401 is formed on the blade. Such a design separates the swing blade 4 from the transmission structure, which not only ensures the efficiency of airflow control, but also facilitates the transmission of power and the flexible rotation of the swing blade 4.

[0035] The connecting protrusion 401 is arranged on the blade. It is not only a key component for airflow guidance, but also a part that is in direct contact with the connecting rod 5. Such a design simplifies the power transmission path from the driving mechanism to the swing blade 4 and improves the response speed and reliability of the mechanism. The connecting column 402 is rotatably arranged in the first positioning hole 301, so that the swing blade 4 can not only rotate around the axis of the connecting column 402 itself, but also can flexibly rotate in the first positioning hole 301 of the bracket 3 through the connecting column 402. The dual rotation mechanism ensures that the swing blade 4 can swing smoothly in the desired direction while maintaining a stable installation position.

[0036] The connecting rod 5 is provided with a plurality of second positioning holes 501 at intervals. The plurality of second positioning holes 501 are provided in one-to-one correspondence with the plurality of connecting protrusions 401 , and each connecting protrusion 401 is rotatably disposed in each of the second positioning holes 501 .

[0037] In this embodiment, a plurality of second positioning holes 501 are provided at intervals on the connecting rod 5, each positioning hole corresponding one-to-one to a connecting protrusion 401 on the pendulum blade 4, and each connecting protrusion 401 is installed on the connecting rod 5 through the second positioning hole 501 and can rotate freely, thereby ensuring that the connecting rod 5 drives all the pendulum blades 4 to move synchronously, and by rotating the connecting protrusion 401 in the second positioning hole 501 and the connecting column 402 in the first positioning hole 301, the pendulum blade 4 can rotate around the axis of the connecting column 402 itself, while each pendulum blade 4 has the flexibility to operate independently, the firmness and stability of the overall structure are also ensured, and each pendulum blade 4 can swing back and forth driven by the connecting rod 5 without causing unnecessary jamming or misalignment.

[0038] The second positioning hole 501 is provided with a deformation opening for avoiding the connecting protrusion 401 and limiting the connecting protrusion 401 to be located in the second positioning hole 501 .

[0039] In this embodiment, in order to facilitate the installation of the swing blade 4, a deformation opening is provided in the second positioning hole 501 for clamping the connecting protrusion 401 into the second positioning hole 501. The deformation opening is made of elastic material to facilitate the disassembly and installation of the connecting protrusion 401.

[0040] The proximal ends of the connecting rod 5 and the driving block 6 are respectively provided with a matching first sliding groove 8 and a first guide column 9. Under the action of external force, the first guide column 9 moves back and forth in the first sliding groove 8.

[0041] In this embodiment, a first slide groove 8 is provided at the proximal end of the connecting rod 5, and a first guide column 9 matching the proximal end of the driving block 6 is provided to ensure that the driving block 6 can slide smoothly and accurately along the up and down path. When the gear 7 rotates forward or reversely, the driving force generated by meshing with the rack 601 on the driving block 6 causes the first guide column 9 to make a reciprocating linear motion along the first slide groove 8 on the connecting rod 5, which is converted into the synchronous swinging of each swing blade 4 through the connecting rod 5 structure, thereby realizing the adjustment of the airflow direction. The cooperation between the first slide groove 8 and the first guide column 9 not only provides guidance for linear motion, but also enhances the stability of the system during movement, reduces unnecessary vibration or deviation, and ensures the synchronization and accuracy of the movement of each swing blade 4.

[0042] The driving block 6 is provided with a second sliding groove 10 along the length direction of the rack 601 . The second sliding groove 10 is slidably matched with a second guide column 11 , and the second guide column 11 is fixed to the housing 1 .

[0043] In this embodiment, a second slide groove 10 is provided on the driving block 6 along the length direction of the rack 601, and a second guide column 11 fixed on the shell 1 is matched therewith to ensure that when the driving block 6 reciprocates along the rack 601, it is not only directly affected by the drive of the gear 7, but also obtains stable support and guidance provided by the shell 1 through the second guide column 11.

[0044] The first chute 8 and the second chute 10 are arranged perpendicular to each other; and

[0045] The bracket 3 and the connecting rod 5 are arranged parallel to each other.

[0046] In this embodiment, the first slide groove 8 and the second slide groove 10 are arranged perpendicular to each other. The first slide groove 8 is responsible for positioning and guiding along the up and down directions, and the second slide groove 10 is responsible for guiding in a direction perpendicular to the first slide groove 8 (left and right directions). Such a design can ensure that the drive block 6 has precise control in both directions. At the same time, the bracket 3 and the connecting rod 5 are arranged parallel to each other, which means that the movement path and force direction of the connecting rod 5 are consistent with the extension line of the bracket 3. Such a setting is conducive to transmitting power, simplifies the force transmission path, and reduces unnecessary stress.

[0047] The present embodiment also provides an air conditioner, including the above-mentioned swing blade mechanism. The specific structure of the air conditioner refers to the above-mentioned embodiment. Since the present air conditioner adopts all the technical solutions of the above-mentioned embodiment, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be described one by one here.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
