Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a support structure, an oscillating assembly, and an air outlet device. Background Technology

[0002] Fans are commonly used electrical appliances for cooling and air circulation. To achieve a wider airflow range, fans often have an oscillation function, which uses a motor to drive the fan head to rotate and change the direction of airflow, thereby expanding the airflow range through repeated oscillation.

[0003] Currently, the oscillation function of fans is usually achieved using a crank-rocker mechanism. Specifically, a motor drives the crank to rotate, which in turn drives the rocker to complete the oscillation motion. However, in actual use, when the user manually rotates the fan chassis or body, the rocker may become the driving component. As the rocker drives the crank to rotate in the opposite direction, it may reach a dead point at a certain position. If the user forcibly rotates the chassis or body at this time, the abnormal tangential force and tumbling torque experienced by the rocker will be directly transmitted to the output shaft of the oscillation motor. These abnormal tangential forces and tumbling torques will be transmitted through the output shaft of the oscillation motor to the motor end cover and internal gears, causing structural damage such as end cover deformation and gear tooth breakage, affecting the fan's lifespan and user experience. Summary of the Invention

[0004] Therefore, it is necessary to provide a support structure, an oscillation assembly, and an air outlet device to address the problem that forcibly rotating the chassis or body by the user can damage the motor.

[0005] A support structure for a head-shaking assembly, the support structure comprising:

[0006] The drive unit has an output shaft that extends longitudinally along a first direction;

[0007] Motor bracket;

[0008] The support unit is connected to the motor bracket of the drive component and is located between the drive component and the motor bracket. The support unit has a support hole that extends through the first direction, and the output shaft passes through the support hole.

[0009] In one embodiment, the support unit includes a support body and a support sleeve. The support body is connected to the drive member and the motor bracket respectively. The support sleeve protrudes from the side of the support body facing the motor bracket in the first direction. The support hole penetrates the support sleeve and extends to the surface of the support body away from the support sleeve.

[0012] In one embodiment, the support body has a first boss protruding from one side surface facing the support sleeve. The first boss is connected to the support sleeve and is arranged circumferentially around the support hole.

[0013] In one embodiment, a second boss is provided on the side surface of the support body away from the support sleeve. The second boss is arranged circumferentially around the support hole. A limiting shoulder is provided at the end of the output shaft facing the support unit. The second boss abuts against the limiting shoulder.

[0014] In one embodiment, the support body includes a support lug, the support lug is further provided with a first mounting hole, the drive member is provided with a motor lug, the motor lug is provided with a second mounting hole, and the motor bracket is provided with a third mounting hole, the first mounting hole, the second mounting hole and the third mounting hole are aligned in the first direction;

[0015] In one embodiment, the support structure further includes a first fastener, which passes through the second mounting hole, the first mounting hole, and the third mounting hole, and fixes the motor lug, the support lug, and the motor bracket to each other.

[0016] In one embodiment, the motor bracket is provided with a positioning structure, the support lug is provided with an intermediate structure, and the motor lug is provided with a mating structure. Both the intermediate structure and the mating structure can be positioned and mated with the positioning structure in the first direction.

[0017] In one embodiment, one of the intermediate structure, the mating structure, and the positioning structure is a positioning post extending longitudinally along the first direction, and the other two are a positioning hole and a limiting hole, respectively. The positioning hole and the limiting hole both extend longitudinally along the first direction, and the positioning post passes through the positioning hole and the limiting hole.

[0018] In one embodiment, the intermediate structure is a positioning hole, and the edge of the support lug is also provided with a positioning notch. The positioning notch is connected to the positioning hole, and the positioning post can enter or exit the positioning hole through the positioning notch.

[0019] In one embodiment, the support lug further includes a buckle that can engage with the drive member.

[0020] In one embodiment, a flange is provided on the circumferential edge of the support body, and the flange is folded toward the side away from the support sleeve.

[0021] In one embodiment, the support body is further provided with a support clearance hole, which penetrates the support body along the first direction and is positioned relative to the gear shaft of the drive member in the first direction.

[0022] A head-shaking assembly, including the support structure described in any of the preceding claims.

[0023] In one embodiment, the oscillating assembly includes a base and a transmission assembly. The base is disposed on the side of the motor bracket away from the drive member. The output shaft is driven to the base via the transmission assembly, and the output shaft causes the motor bracket to rotate relative to the base via the transmission assembly.

[0024] In one embodiment, the transmission assembly includes a crank and a connecting rod, one end of the crank being disposed at the portion of the output shaft extending out of the support hole, and the other end being connected to one end of the connecting rod, the other end of the connecting rod being connected to the base;

[0025] The motor bracket is also provided with a transmission clearance hole. The connecting rod is fixedly connected to the base through the transmission clearance hole, and the base rotates relative to the motor bracket through the transmission clearance hole.

[0026] And / or, the oscillating assembly further includes a pressure plate mounted on the side of the motor bracket away from the drive member, and the base is rotatably disposed between the pressure plate and the motor bracket.

[0027] An air outlet device includes an oscillating assembly as described in any of the preceding claims.

[0028] In one embodiment, the air outlet device is a tower fan;

[0029] Alternatively, the air outlet device may be a standing air conditioner;

[0030] Alternatively, the air outlet device may be a vertical heater.

[0031] The aforementioned support unit, positioned between and connected to the drive component and motor bracket, features a through-hole through which the output shaft of the drive component passes. Under normal operating conditions, the support sleeve does not bear any load. However, when the output shaft is subjected to abnormal force, the support unit supports and limits its movement, preventing displacement caused by tangential or overturning forces that could lead to deformation of the drive component's end cover, breakage of gears, or other internal structural damage. This effectively protects the drive component. When applied to an air outlet device, if the user forcibly rotates the chassis or body of the air outlet device, causing abnormal force on the output shaft, the support unit, fixed to the motor bracket, supports and limits the output shaft, effectively preventing deformation of the drive component's end cover or damage to its internal gears. This significantly improves the lifespan and safety of the air outlet device. Attached Figure Description

[0054] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0055] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0056] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0058] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0059] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0060] See Figure 1 and Figure 2 This application provides a support structure comprising a motor bracket 200, a support unit 100, and a drive component 300. The support unit 100 is connected to both the drive component 300 and the motor bracket 200, and is located between the drive component 300 and the motor bracket 200. The motor bracket 200 is used to fix the drive component 300 to the housing of the air outlet device, thereby enabling the drive component 300 and the support unit 100 to be fixed to the entire air outlet device via the motor bracket 200, thus facilitating the assembly of the drive component 300. The drive component 300 can be a motor, and it has an output shaft 310, which provides power to the air outlet device to achieve its oscillating function.

[0061] Among them, see Figure 3 and Figure 4 To support and protect the output shaft 310 of the drive unit 300, a support hole 131 is provided on the support unit 100, extending along the first direction X. The output shaft 310 passes through the support hole 131. The support hole 131 allows the output shaft 310 of the drive unit 300 to pass through, and the support unit 100 supports and limits the drive unit 100 through the support hole 131. This ensures that when the output shaft 310 is subjected to abnormal force, the external force can be transferred to the support unit 100, thereby preventing displacement of the output shaft 310 and damage to the drive unit 300.

[0062] Specifically, when the output shaft 310 is subjected to abnormal forces, these forces are decomposed into tangential forces and rotational forces. These forces are transmitted to the support unit 100 via the output shaft 310 and are ultimately borne by the connection between the support unit 100 and the motor bracket 200. Thus, when the output shaft 310 is subjected to abnormal forces, the support unit 100 on the motor bracket 200 can support the output shaft 310, preventing displacement of the output shaft 310 due to tangential and rotational forces, which could lead to deformation of the drive unit 300 end cover, broken gear teeth, or other internal structural damage.

[0063] Furthermore, the support unit 100 is connected to both the motor bracket 200 and the drive component 300, as follows: Figure 1As shown, the support body 110 serves as an intermediate component connecting the motor bracket 200 and the drive component 300. It not only supports and limits the output shaft 310, but also fixes the drive component 300 to the motor bracket 200.

[0064] The aforementioned support unit 100, which is disposed between and connected to the drive member 300 and the motor bracket 200, has a through support hole 131. The output shaft 310 of the drive member 300 passes through the support hole 131. Under normal use, the support sleeve 130 does not participate in the force bearing of the output shaft 310. However, when the output shaft 310 is subjected to abnormal force, the support unit 100 can support and limit the output shaft 310, preventing displacement of the output shaft 310 due to tangential force and overturning force, which could lead to deformation of the end cover of the drive member 300, breakage of gear teeth, or other internal structural damage. This effectively protects the drive member 300. When the aforementioned support unit 100 is applied to the air outlet device, it can support and limit the output shaft 310 when the user forcibly rotates the chassis mechanism or body mechanism of the air outlet device, causing abnormal force on the output shaft 310. Since the drive component 300 is fixed on the motor bracket 200 through the support unit 100, the support unit 100 can support and limit the output shaft 310, effectively preventing the end cover of the drive component 300 from deforming or the internal gears of the drive component 300 from being damaged, thereby effectively improving the service life and safety of the air outlet device.

[0065] In some embodiments of this application, the support unit 100 includes a support body 110 and a support sleeve 130. The support body 110 is connected to the drive member 300 and the motor bracket 200 respectively. The support sleeve 130 protrudes from the side of the support body 110 facing the motor bracket 200 in the first direction X. The support hole 131 penetrates the support sleeve 130 and extends to the side surface of the support body 110 away from the support sleeve 130.

[0066] When the output shaft 310 passes through the support hole 131, the support sleeve 130 is clearance-fitted with the outer wall of the output shaft 310. The support sleeve 130 mainly supports and limits the output shaft 310, and is used to withstand the abnormal tangential force and overturning force generated when the user forcibly rotates the chassis mechanism or body mechanism of the air outlet device. The support body 110 is mainly used to fix the main body of the drive component 300. In this way, while ensuring the support effect on the output shaft 310, the volume of the entire support unit 100 is reduced, thereby reducing the space occupied by the support unit 100 in the air outlet device, which is conducive to improving the space utilization rate of the internal structure of the air outlet device.

[0067] In some embodiments of this application, the support sleeve 130 is integrally formed with the support body 110, thereby connecting the support body 110 and the support sleeve 130 during the forming process. This eliminates the need for additional components to connect the support sleeve 130 and the support body 110, saving parts and improving assembly efficiency. It is understood that when the support sleeve 130 and the support body 110 are integrally formed, the support hole 131 is a through hole, penetrating both the support sleeve 130 and the support body 110. Optionally, the support unit 100 is a sheet metal part. Compared to plastic parts, sheet metal parts offer better support strength, which is more conducive to the integral forming of the support sleeve 130 and the support body 110, and also better facilitates the support unit 100's support of the output shaft 310.

[0068] In other embodiments, when the support sleeve 130 is formed in separate parts, the support sleeve 130 and the support body 110 need to be connected by additional components such as bolts and clips 115. In this case, the support hole 131 consists of two parts: a sleeve hole extending through the support sleeve 130 in the first direction X, and a main body hole extending through the support body 110 in the first direction X. Furthermore, when the support sleeve 130 is installed on the support body 110, the sleeve hole and the main body hole are aligned and interconnected, so that the sleeve hole and the main body hole together form the support sleeve 130 for the output shaft 310 to pass through.

[0069] In actual use, when the user forcibly rotates the chassis mechanism or body mechanism of the air outlet device, causing abnormal force on the output shaft 310, the external force will cause the output shaft 310 to deflect radially and axially. The radial deflection forms a tangential force, and the axial deflection forms a reversing force. Then, the output shaft 310 abuts against the inner wall of the support hole 131, so that the support sleeve 130 can withstand the tangential force and reversing force from the output shaft 310. Finally, the connection between the support body 110 and the support sleeve 130 will also bear a certain external force.

[0070] Therefore, the connection structure at the junction of the support body 110 and the support sleeve 130 determines the support effect of the support unit 100 on the output shaft 310. To this end, a first boss 111 protrudes from one side of the support body 110 facing the support sleeve 130. The first boss 111 is connected to the support sleeve 130 and is circumferentially arranged around the support hole 131. That is, the first boss 111 is annular. The support sleeve 130 is mounted on the first boss 111. Through the integral molding of the support body 110 and the support sleeve 130, the support body 110 has the first boss 111 at the junction with the support sleeve 130. This first boss 111 increases the structural strength at the junction of the support body 110 and the support sleeve 130, effectively improving the support strength of the support unit 100 on the output shaft 310. In some embodiments, the first boss 111 can also cooperate with the motor bracket 200 to achieve the limiting installation of the support unit 100. Specifically, the first boss 111 can cooperate with the limiting groove and other structures on the motor bracket 200 to achieve the quick positioning of the support unit 100 and the motor bracket 200, so as to facilitate the assembly of the support unit 100 and the motor bracket 200.

[0071] Furthermore, in actual use, if the user forcibly rotates the chassis mechanism or body mechanism of the air outlet device, causing abnormal force on the output shaft 310, most of the external force is in the radial direction of the output shaft 310, but there is also a situation where some external force is along the axial direction of the output shaft 310. For example, when the user pulls the body mechanism outward, the output shaft 310 is subjected to an external force in the axial direction, i.e., the first direction X, causing the output shaft 310 and the drive component 300 to move in the axial direction.

[0072] Based on this, in some embodiments, see [reference] Figure 4 and Figure 5 A second boss 112 protrudes from the side of the support body 110 away from the support sleeve 130 and is arranged circumferentially around the support hole 131. The second boss 112 abuts against the limiting shoulder 311 on the output shaft 310. The output shaft 310 has a limiting shoulder 311 at the end facing the support unit 100. The limiting shoulder 311 protrudes radially from the body of the output shaft 310. When the output shaft 310 tends to move axially, the abutment between the second boss 112 and the limiting shoulder 311 prevents axial movement of the output shaft 310, thereby ensuring the normal operation of the drive component 300. Furthermore, when the support sleeve 130 and the support body 110 are integrally formed, the second boss 112 also increases the connection strength between the support sleeve 130 and the support body 110 at the connection point, further enhancing the support strength of the support unit 100 for the output shaft 310. In addition, since the support unit 100 is a sheet metal part, it is easier to form the first boss 111 or the second boss 112 by extrusion and bending.

[0073] In some embodiments of this application, see [reference] Figure 1 , Figure 2 and Figure 6 To connect the support body 110 with the drive component 300 and the motor bracket 200, the support body 110 includes a support lug 101, which is provided with a first mounting hole 118. The drive component 300 is provided with a motor lug 350, which is provided with a second mounting hole 330. Furthermore, the motor bracket 200 is provided with a third mounting hole 210. The second mounting hole 330, the first mounting hole 118, and the third mounting hole 210 are aligned with each other in the first direction X.

[0074] Furthermore, the support unit also includes a first fastener, which passes through the second mounting hole 330, the first mounting hole 118 and the third mounting hole 210, thereby fixing the motor lug 350, the support lug 101 and the motor bracket 200 to each other. This allows the motor bracket 200, the support body 110 and the drive component 300 to be fixed to each other. Then, the motor bracket 200 is fixed to the entire air outlet device, thus fixing the support unit 100 and the drive component 300 to the entire air outlet device.

[0075] Optionally, the first fastener is a bolt, and the third mounting hole 210 is a threaded hole, so that the motor lug 350, the support lug 101, and the motor bracket 200 are fixed to each other through the threaded connection between the first fastener and the third mounting hole 210. In some other embodiments, the first mounting hole 118 can also be a threaded hole. Further, the first fastener includes two fasteners, and the first mounting hole 118, the second mounting hole 330, and the third mounting hole 210 also include two fasteners. Each first mounting hole 118, one of the second mounting holes 330, and one of the third mounting holes 210 are aligned, and the first fastener passes through one of the first mounting holes 118 and the corresponding second mounting hole 330 and is threadedly connected to the corresponding third mounting hole 210.

[0076] To improve the fixing reliability between the support body 110 and the driving component 300, the support unit 100 also includes a buckle 115. The buckle 115 can engage with the driving component 300, so that the support body 110 can be fixed to the driving component 300 again by means of the buckle 115 in addition to being fixed by the first fastener, thereby improving the reliability of the connection between the support body 110 and the driving component 300. Furthermore, there are at least two buckles 115, and all buckles 115 are spaced apart along the edge of the support body 110. Each buckle 115 is used to engage with the housing of the driving component 300, thereby further improving the fixing reliability between the support body 110 and the driving component 300 by means of multiple buckles 115.

[0077] In one specific embodiment, the support lug 101 is provided with a snap fastener 115, and the support lug 101 is fastened to the motor lug 350 through the snap fastener 115. There are at least two support lugs 101, and each support lug 101 is provided with at least one snap fastener 115. By fastening the support lug to the motor lug, quick positioning and fastening are possible, which is more convenient and faster. There is no need to set other protrusions or grooves around the motor body, which improves the reliability of the fixation between the support body 110 and the drive component 300.

[0078] In some embodiments, the motor bracket 200 is provided with a positioning structure, the support lug 101 is provided with an intermediate structure, and the motor lug 350 is provided with a mating structure. Both the intermediate structure and the mating structure can be positioned and mated with the positioning structure in the first direction X. Thus, through the limiting fit of the positioning post 220, the limiting hole 340, and the positioning hole 113, the support body 110 and the drive component 300 can be quickly positioned on the motor bracket 200, thereby achieving rapid alignment between the second mounting hole 330, the first mounting hole 118, and the third mounting hole 210. This allows the first fastener to pass through the second mounting hole 330, the first mounting hole 118, and the third mounting hole 210, enabling rapid installation of the drive component 300, the support body 110, and the motor bracket 200.

[0079] In some specific embodiments, the positioning structure is a positioning post 220 that is set on the motor bracket 200 and extends longitudinally along the first direction X. The intermediate structure is a positioning hole 113 that is set on the support body 110 and extends through along the first direction X. The mating structure is a limiting hole 340 set on the drive member 300. The positioning post 220 passes through the positioning hole 113 and the limiting hole 340, so that the intermediate structure and the mating structure can be positioned and mated with the positioning structure in the first direction X.

[0080] It is understood that in some other embodiments, the intermediate structure and the mating structure can also be positioning posts, requiring only that one of the intermediate structure, the mating structure, and the positioning structure is a positioning post 220 extending along the first direction X, and the other two are a positioning hole 113 and a limiting hole 340, respectively. In still other embodiments, the intermediate structure, the mating structure, and the positioning structure can also be positioning buckles, positioning protrusions, positioning grooves, etc., which are not limited here.

[0081] Furthermore, based on the positioning hole 113 in the middle structure, a positioning notch 114 is also provided on the edge of the support lug 101. The positioning notch 114 is connected to the positioning hole 113, and the positioning post 220 can enter or exit the positioning hole 113 through the positioning notch 114. This allows the positioning post 220 to be installed into the positioning hole 113 through the positioning notch 114 when assembling the support unit 100, without having to insert the support body 110 into the positioning hole 113 from one end of the positioning post 220, thus simplifying the assembly steps of the support body 110. Optionally, at least two support ears 101 are provided, and multiple support ears 101 are spaced apart along the edge of the support body 110. Each support ear 101 is provided with a positioning hole 113 and a positioning notch 114. The positioning notch 114 and the positioning hole 113 on each support ear 101 are connected. The aforementioned positioning post 220 and limiting hole 340 are also included in at least two. The number of positioning posts 220, limiting holes 340, positioning holes 113 and positioning notches 114 are in one-to-one correspondence. Each positioning post 220 passes through one of the positioning holes 113 and limiting holes 340.

[0082] In some embodiments of this application, a flange 116 is also provided on the circumferential edge of the support body 110. The flange 116 is folded toward the side away from the support sleeve 130, that is, the flange 116 is folded toward the side of the drive member 300. When the drive member 300 is installed on one side of the support body 110, the flange 116 can also be arranged around the circumference of the drive member 300, thereby improving the structural strength and rigidity of the entire support structure and enhancing the load-bearing capacity of the support unit 100 through the flange 116.

[0083] In some embodiments of this application, a support clearance hole 117 is also provided on the support body 110. The support clearance hole 117 penetrates the support body 110 along the first direction X, and is positioned relative to the gear shaft 320 of the drive member 300 in the first direction X. In actual use, when the support body 110 and the drive member 300 are fixed together, the support body 110 will apply a certain compressive force to the surface of the drive member 300. This compressive force will cause a slight displacement of the gear shaft 320 of the drive member 300, but over time it will affect the normal movement of the gear and gear shaft 320 inside the drive member 300. Therefore, through the aforementioned support clearance hole 117, when the support body 110 and the drive member 300 are fixed together, since the support clearance hole 117 is aligned with the gear shaft 320, the support body 110 will not apply compressive force to the gear shaft 320 at the position of the gear shaft 320, thus ensuring the service life of the drive member 300.

[0084] This application embodiment also provides a oscillating assembly, including the support structure in any of the previous embodiments. The oscillating assembly is used for the body mechanism of the air outlet device to rotate relative to the chassis mechanism, thereby realizing the oscillating function of the air outlet device. Furthermore, through the aforementioned support structure, when the user forcibly rotates the chassis mechanism or body mechanism of the air outlet device, causing abnormal force on the output shaft 310, the support structure can support and limit the output shaft 310, effectively preventing deformation of the end cover of the drive component or damage to the internal gears of the drive component, thereby effectively improving the service life and safety of the air outlet device.

[0085] In some embodiments of this application, see [reference] Figure 7 , Figure 8 and Figure 9 The oscillating assembly includes a base 400 and a transmission assembly 410. The base 400 is located on the side of the motor bracket 200 away from the drive component 300. The output shaft 310 is connected to the base 400 via the transmission assembly 410, causing the motor bracket 200 to rotate relative to the base 400. In actual use, when the air outlet device normally activates the oscillating function, the motor bracket 200 is fixedly connected to the body mechanism and rotates relative to the base 400. Since the base 400 is fixedly connected to the chassis mechanism, which is placed on the ground, the chassis mechanism will not move due to the gravity of the air outlet device. That is, the base 400 does not rotate relative to the ground. Therefore, the drive component 300 drives the transmission assembly 410 to rotate, thereby causing the motor bracket 200, the drive component 300, and the body mechanism to rotate relative to the base 400, which in turn causes the head of the air outlet device to rotate, thus realizing the oscillating function of the air outlet device.

[0086] It should be noted that the base 400 and the motor bracket 200 are in relative motion. When the base 400 is stationary, the motor bracket 200 can rotate relative to the base 400 under the action of the driving component 300 and the transmission component 410. When the motor bracket 200 is stationary, the base 400 can rotate relative to the motor bracket 200 under the action of the driving component 300 and the transmission component 410.

[0087] In some embodiments, see Figure 10 and Figure 11The transmission assembly 410 includes a crank 411 and a connecting rod 412. One end of the crank 411 is located at the portion of the output shaft 310 extending out of the support hole 131, and the other end is connected to one end of the connecting rod 412. The other end of the connecting rod 412 is connected to the base 400. A transmission clearance hole 230 is also provided on the motor bracket 200. The connecting rod 412 is fixedly connected to the base 400 through the transmission clearance hole 230, and the base 400 rotates relative to the motor bracket 200 through the transmission clearance hole 230. The end of the connecting rod 412 connected to the base 400 is eccentrically positioned relative to the axis of the base 400, so that when the output shaft 310 rotates, the crank 411 drives the connecting rod 412 to swing, ultimately achieving the rotation of the base 400 relative to the motor bracket 200. It is understood that in some other embodiments, the transmission assembly 410 may also be a gear, etc., and is not limited here.

[0088] Furthermore, the air outlet device also includes a second fastener 231, through which the connecting rod 412 is fixedly connected to the base 400. Specifically, the base 400 is provided with a base screw post 420, and the end of the screw post is provided with a base threaded hole 421. The connecting rod 412 is provided with a rod fixing hole 423. The base screw post 420 passes through the transmission clearance hole 230. The second fastener 231 is a bolt or screw. The second fastener 231 passes through the rod fixing hole 423 and the rod fixing hole 423 and is threadedly connected to the base threaded hole 421, thereby fixing the connecting rod 412 to the base 400.

[0089] In some embodiments, the air outlet device further includes a pressure plate 500, which is mounted on the side of the motor bracket 200 away from the drive component. A base 400 is rotatably disposed between the pressure plate 500 and the motor bracket 200. The pressure plate 500 limits the position of the base 400 on the motor bracket 200, ensuring that the base 400 rotates relative to the motor bracket 200 while the cooperation between the pressure plate 500 and the motor bracket 200 keeps the base 400 confined between them. Furthermore, the oscillating assembly also includes a third fastener 241. The pressure plate 500 has a fixing screw through hole 511, and the motor bracket 200 has a fixing screw post 240 with a fixing threaded hole 242. The third fastener 241 passes through the fixing screw through hole 511 and is threadedly connected to the fixing threaded hole 242, thereby fixing the pressure plate 500 on the motor bracket 200.

[0090] Furthermore, the pressure plate 500 is also provided with a buckle 510, and the motor bracket 200 is also provided with a socket 250. The extension direction of the socket 250 intersects with the first direction. After the buckle 510 is inserted into the socket 250, the pressure plate 500 and the motor bracket 200 can be fixedly connected in the first direction through the buckle 510, thereby improving the installation strength of the pressure plate 500 and the motor bracket 200 in the first direction X.

[0091] This application embodiment also provides an air outlet device, including a body mechanism and a support structure as described in any of the above embodiments. The body mechanism is fixedly connected to the motor bracket 200. When the base 400 does not rotate relative to the ground, under the action of the drive component 300, the motor bracket 200 rotates relative to the base 400 through the transmission component 410, thereby realizing the oscillation function of the air outlet device. See also... Figure 12 The body structure is provided with mounting screw posts 610. The side of the motor bracket 200 connected to the support unit 100 is also provided with screw post through holes 260. The mounting screw posts 610 are inserted into the screw through holes and fixed in the screw post through holes 260 by bolts and other fasteners, so that the oscillating component can be installed on the whole air outlet device.

[0092] Optionally, the aforementioned air outlet device can be a tower fan, a standing air conditioner, or a standing heater. It is understood that in other embodiments, the aforementioned air outlet device can also be other electrical appliances that require oscillating airflow, and this is not limited thereto.

[0093] The aforementioned support unit 100 has at least the following advantages:

[0094] A support unit 100 is provided between the drive component 300 and the motor bracket 200, and is connected to both the drive component 300 and the motor bracket 200. A through support hole 131 is provided on the support unit 100, and the output shaft 310 of the drive component 300 passes through the support hole 131. Thus, under normal use, the support sleeve 130 does not participate in the force of the output shaft 310. However, when the output shaft 310 is subjected to abnormal force, the support unit 100 can support and limit the output shaft 310, so as to prevent the output shaft 310 from being displaced due to external force, which would cause internal structural damage such as deformation of the end cover of the drive component 300 and breakage of gear teeth, thus protecting the drive component 300. When the aforementioned support unit 100 is applied to the air outlet device, it can support and limit the output shaft 310 when the user forcibly rotates the chassis mechanism or body mechanism of the air outlet device, causing abnormal force on the output shaft 310. This effectively prevents the end cover of the drive component 300 from deforming or the internal gears of the drive component 300 from being damaged, thereby effectively improving the service life and safety of the air outlet device.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
