Description
Technical Field
[0001] This utility model relates to the field of air conditioner accessories technology, and in particular to a blade structure for an air conditioner cabinet unit. Background Technology
[0002] Air conditioner louvers are air-guiding components located at the air outlet of an air conditioner. They guide the airflow generated by the cross-flow fan and adjust the airflow direction. The stability of the louvers affects the airflow performance of the air conditioner. In floor-standing air conditioners, the louvers are typically fixed using a shaft-hole fit, with two motor shafts driving the louvers to rotate. Therefore, the connection method between the louvers and the motor shafts plays a crucial role in the stability of the louvers' operation.
[0003] Currently, the ends of the air conditioner blades are assembled with the motor crank through a shaft hole. During long-term use, the gap between the air conditioner blades and the faceplate may become uneven due to gravity. Furthermore, this connection method requires high strength from the motor shaft sleeve. Currently, the motor shaft is generally made of POM material with average strength performance. During long-term use, this may cause the motor crank to fail and fail to effectively drive the air conditioner blades. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a blade structure for an air conditioner cabinet that can effectively improve the assembly strength between the air conditioner blades and the motor crank and improve the stability of the blade operation.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The swivel structure of an air conditioner cabinet unit includes a swivel body and an extension plate connected to one end of the swivel body. A swivel drive assembly is fixedly installed on the extension plate. The swivel drive assembly includes a drive block, a crank, and a pin. The drive block is fixed on the extension plate and has a drive hole parallel to the length direction of the swivel body and a pin hole perpendicular to the drive hole. The drive hole and the pin hole are connected. One end of the crank has a radially extending locking hole, and the other end of the crank has an axially extending motor connection hole. The crank is inserted into the drive hole, the locking hole is aligned with the pin hole, and the pin is engaged with the locking hole and the pin hole.
[0006] As a further improvement to the above solution, it also includes a wrapping shell with downwardly bent wing plates on both sides; a pin is fixedly connected to the wrapping shell, the wrapping shell is fastened to the periphery of the drive block and detachably connected to the drive block; the wing plates of the wrapping shell are in contact with the two sides of the drive block.
[0007] As a further improvement to the above solution: the drive block is also fixedly connected to a fixing post, the fixing post having an internal threaded hole, and the casing is threadedly connected to the internal threaded hole of the fixing post by screws.
[0008] As a further improvement to the above solution: a fixing plate is also fixedly connected to the outer shell. The fixing plate has a groove, and a screw passes through the groove through the fixing plate and is threadedly connected to the inner threaded hole of the fixing post.
[0009] As a further improvement to the above solution: multiple anti-slip strips are provided on the outer side of the wing plate of the wrapping shell. The anti-slip strips extend in a direction parallel to the crank axis and are evenly distributed at intervals in the height direction of the wrapping shell.
[0010] As a further improvement to the above solution: the drive block is also provided with a first reinforcing rib and a second reinforcing rib; the first reinforcing rib is a portal-shaped reinforcing rib, and multiple first reinforcing ribs are fixed on the periphery of the drive block and evenly distributed at intervals along the length direction of the blade body, and the two ends of the first reinforcing rib are fixedly connected to the extension plate; the second reinforcing rib is an I-shaped reinforcing rib composed of a connecting plate and two side plates, and the two side plates of the second reinforcing rib are fixedly connected between the drive block and the blade body, and the connecting plate of the second reinforcing rib abuts against the fixed column.
[0011] As a further improvement to the above solution: the pin is a square pin, and both the lock hole and the pin hole are square holes adapted to the square pin.
[0012] As a further improvement to the above solution: the pin is a three-section structure consisting of a first section, a second section, and an elastic buckle connected in one piece; the first section is fixedly connected to the outer shell, the second section is connected between the first section and the elastic buckle, and the outer diameter of the first section is larger than that of the second section; the lock hole is adapted to the second section, and the pin hole is composed of an upper pin hole and a lower pin hole connected together, the upper pin hole is adapted to the first section, the lower pin hole is adapted to the second section, and the elastic buckle is locked below the lower pin hole.
[0013] The beneficial effects of this utility model are as follows: This utility model improves the connection and assembly structure between the air conditioner's oscillating blades and the motor. It adds an oscillating blade drive assembly and, after the drive block in the oscillating blade drive assembly is engaged with the crank of the motor through a plug-in method, a pin is inserted into the drive block from a direction perpendicular to the crank to lock the drive block and the crank, thereby effectively fixing the relative position of the oscillating blades and the crank, making the connection between the oscillating blades and the crank stable and preventing other relative movements. This utility model effectively strengthens the assembly strength between the oscillating blades and the crank, enabling the crank to stably drive the oscillating blades to operate, and the gap between the oscillating blades and the face frame will not change, ensuring the stability of the air conditioner's oscillating blade operation.

Detailed Implementation
[0018] To facilitate understanding of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.
[0019] In the description of this utility model, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] like Figure 1 and Figure 2 As shown, the air conditioner cabinet unit's louver structure disclosed in this utility model includes a louver body 100 and a louver drive assembly 300. This utility model extends the end of the louver body 100 that cooperates with the motor, adding an extension plate 200 integrally connected to the louver body 100 as the mounting location for the louver drive assembly 300. This utility model improves the connection strength and stability between the louver body 100 and the motor by setting the louver drive assembly 300.
[0021] Specifically, such as Figure 1 and Figure 2As shown, the oscillating blade drive assembly 300 used in this utility model includes a drive block 400, a crank 500, and a pin 600. The drive block 400 is fixed on the extension plate 200 of the oscillating blade body 100, and has a drive hole that mates with the crank 500 and a pin hole 410 that mates with the pin 600. The drive hole extends along the length direction of the oscillating blade body 100, i.e., along the axial direction of the crank 500. The pin hole 410 extends in a direction perpendicular to the drive hole. The pin hole 410 and the drive hole communicate inside the drive block 400 to form a cross-shaped communication channel. One end of the crank 500 of the motor is an insertion end that mates with the pin hole 410, and the other end is fixedly connected to the motor through an axially extending motor connection hole. The insertion end of the crank 500 is provided with a locking hole 510, which extends in a direction perpendicular to the axial direction of the crank 500, i.e., it penetrates the insertion end of the crank 500 in the radial direction. The insertion end of the crank 500 is inserted into the drive hole of the drive block 400. The locking hole 510 is aligned with the pin hole 410. The pin 600 is inserted into the drive block 400 and forms a plug-in engagement with the pin hole 410 and the locking hole 510, thereby achieving locking between the drive block 400 and the crank 500. This utility model fixes the relative position between the louver body 100 and the crank 500 through the cooperation between the drive block 400, the crank 500 and the pin 600 in the louver drive assembly 300. This prevents the gap between the face frame and the louver body 100 from changing during the use of the air conditioner. The crank 500 is subjected to more even force, which strengthens the assembly strength between the louver body 100 and the crank 500 and makes the crank 500 less prone to failure. It can also reduce the thermal expansion noise caused by the thermal expansion and contraction of the louver body 100, which helps to reduce noise.
[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the pendulum drive assembly 300 of this utility model also includes a housing 700, which is used to improve the installation efficiency of the pin 600 and the overall strength of the pendulum drive assembly 300 after assembly. Figure 3As shown, the enclosure 700 includes a top plate and two wing plates fixedly connected to both sides of the top plate. The top plate is horizontally positioned, and the two wing plates are formed by vertically bending downwards from both sides of the top plate. A pin 600 is fixedly connected to the inner side of the top plate of the enclosure 700. During assembly, the pin 600 is aligned with the pin hole 410 on the drive block 400, and then the enclosure 700 is snapped downwards onto the periphery of the drive block 400, so that the two wing plates of the enclosure 700 fit snugly against the two sides of the drive block 400. To improve the fit between the drive block 400 and the enclosure 700, the top surface of the drive block 400 can be set as an arc surface, and the connection between the top plate and the wing plates of the enclosure 700 can be set as an arc transition, so that the enclosure 700 and the drive block 400 fit tightly together. By using the encapsulation shell 700, the pin 600 can be assembled by hand using the encapsulation shell 700 during the assembly of the oscillating blade drive assembly 300, which is easier to operate and can improve assembly efficiency. In addition, the encapsulation shell 700 completely encapsulates the drive block 400, which can improve the overall strength of the oscillating blade drive assembly 300 and can also cover the connection parts, which helps to improve the aesthetics.
[0023] Furthermore, in order to improve the assembly efficiency of the enclosure 700, such as... Figure 2 As shown, anti-slip strips 730 can also be provided on the wing plates of the enclosure 700; multiple anti-slip strips 730 are provided on the outer surfaces of both wing plates of the enclosure 700, and the anti-slip strips 730 extend in a direction parallel to the axial direction of the crank 500 and are evenly distributed at intervals in the height direction of the enclosure 700.
[0024] Furthermore, to improve the connection strength between the casing 700 and the drive block 400, this invention also includes a fixing post 420, which is vertically fixed to the extension plate 200. The fixing post 420 has an axially extending internal threaded hole, and the casing 700 has a corresponding connecting hole. Screws 710 are used to fix the casing 700 and the fixing post 420 together. A fixing plate 720 can be integrally formed on the casing 700, with the connecting hole located on it. A groove is provided on the fixing plate 720, and the connecting hole is located within the groove. The screw 710 passes through the groove into the fixing plate 720 and is threadedly connected to the internal threaded hole of the fixing post 420. The groove on the fixing plate 720 conceals the end of the screw 710, preventing it from protruding.
[0025] The drive block 400 serves as the drive connection between the motor crank 500 and the vane body 100. During the motor-driven rotation of the air conditioner vane, the connection between the vane body 100 and the drive block 400 is subjected to strong torque. To prevent deformation and damage to the vane body 100, this invention improves the strength of the connection by providing reinforcing ribs. Figure 2As shown, this utility model employs two types of reinforcing ribs: a first reinforcing rib 430 and a second reinforcing rib 440. The first reinforcing rib 430 is a gate-shaped reinforcing rib resembling an arch structure, while the second reinforcing rib 440 is an I-shaped reinforcing rib composed of a connecting plate and two side plates. Multiple first reinforcing ribs 430 are fixed to the periphery of the drive block 400 and evenly distributed along the length of the oscillating blade body 100. The two ends of the first reinforcing rib 430 are fixedly connected to the extension plate 200. The two side plates of the second reinforcing rib 440 are fixedly connected between the drive block 400 and the oscillating blade body 100, and the connecting plate of the second reinforcing rib 440 abuts against the fixing column 420.
[0026] Furthermore, in order to improve the locking effect of the pin 600 on the drive block 400 and the crank 500 and to achieve circumferential limiting of the pin 600, the pin 600 in this utility model adopts a square pin with a rectangular cross-section, and the locking hole 510 and the pin hole 410 are both set as square holes adapted to the square pin; similarly, the insertion end of the crank 500 can also be set as a square insertion end, and the drive hole is also set as a square hole adapted to the square insertion end.
[0027] To improve the locking effect of the latch 600 on the drive block 400 and the crank 500, such as Figure 3 As shown, this utility model further optimizes the structure of the pin 600 and the pin hole 410; the pin 600 is set as a three-section structure composed of a first segment 610, a second segment 620 and an elastic buckle 630 connected in one piece; the first segment 610 is fixedly connected to the enclosure shell 700, the second segment 620 is connected between the first segment 610 and the elastic buckle 630, and the outer diameter of the first segment 610 is larger than the outer diameter of the second segment 620; the locking hole 510 is adapted to the second segment 620, and the pin hole 410 is composed of an upper pin hole and a lower pin hole connected together; after the pin 600 is inserted into the drive block 400, the first segment 610 of the pin 600 is adapted to the upper pin hole, the second segment 620 of the pin 600 is adapted to the lower pin hole, and the elastic buckle 630 of the pin 600 passes through the lower pin hole and locks below the lower pin hole.
