[0046] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0049] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict.
[0050] In the related art, in order to ensure the relative rotation between the rotating shaft 31 and the shaft sleeve 32, the gap fit is adopted between the rotating shaft 31 and the shaft sleeve 32, but if the fit gap between the rotating shaft 31 and the shaft sleeve 32 is too large, the rotating shaft 31 is easy to swing / shake (horizontal direction) during the rotation relative to the shaft sleeve 32, which causes the violent swing / shake during the angle adjustment of the machine head, and affects the stability of the whole machine. Based on the above defects, the application provides a supporting structure and an air outlet device, for details, see the description below.
[0051] The embodiments of the utility model will be described below in combination with Figures 1 to 7 .
[0052] As Figure 1 and Figure 2As shown, according to the embodiment of the utility model, on the one hand, a support structure is disclosed, which is applied to an air outlet device, the support structure comprises a first support 1, a second support 2, a rotating assembly 3 and a limiting structure, wherein the second support 2 is arranged at the bottom of the first support 1, a containing cavity is formed between the second support 2 and the first support 1, the rotating assembly 3 is arranged in the containing cavity, the rotating assembly 3 comprises a rotating shaft 31 and a shaft sleeve 32, the rotating shaft 31 is rotatably sleeved in the shaft sleeve 32, the rotating shaft 31 is fixedly connected with the first support 1, the shaft sleeve 32 is fixedly connected with the second support 2, the rotating shaft 31 rotates relative to the shaft sleeve 32, thereby driving the first support 1 to rotate together, the angle adjustment of the air outlet device is realized, and the limiting structure is arranged between the first support 1 and the shaft sleeve 32, and the limiting structure is used for limiting the swing of the first support 1 relative to the shaft sleeve 32.
[0053] The support structure of the application, the head is fixedly connected with the first support 1, when the air outlet device needs to adjust the air outlet angle, the rotating shaft 31 rotates relative to the shaft sleeve 32, thereby driving the first support 1 fixedly connected with the rotating shaft 31 to rotate together, so as to drive the head to rotate at an angle, the adjustment of the air outlet angle of the air outlet device is realized, the limiting structure is arranged between the shaft sleeve 32 and the first support 1, in the process that the first support 1 rotates with the rotating shaft 31, the limiting structure can limit the swing of the first support 1 relative to the shaft sleeve 32, thereby limiting the swing of the head, avoiding the violent shaking of the head in the process of angle adjustment, and improving the stability and reducing the jamming feeling in the process of angle adjustment of the air outlet device, and without the need of arranging bearing parts, the setting cost is reduced.
[0054] Preferably, the shaft sleeve 32 is made of self-lubricating material, so as to reduce the friction resistance between the shaft sleeve 32 and the rotating shaft 31, and ensure the smooth and stable rotation of the head. For example, the shaft sleeve 32 can be made of POM material, but is not limited thereto.
[0055] As shown in Figure 2 , Figure 5 , and Figure 6 in some embodiments, the limiting structure comprises a first convex rib 121 and a second convex rib 321, wherein the first convex rib 121 is located on the inner wall of the first support 1 and is arranged to extend towards the shaft sleeve 32, the second convex rib 321 is located on the outer wall of the shaft sleeve 32 and is arranged to extend towards the first convex rib 121, the second convex rib 321 and the first convex rib 121 are clearance fitted, and the first convex rib 121 and the second convex rib 321 abut in the case that the first support 1 swings relative to the shaft sleeve 32.
[0056] The first rib 121 extends toward the bushing 32 and the second rib 321 extends toward the first rib 121. The cooperation between the second rib 321 and the first rib 121 reduces the clearance between the first bracket 1 and the bushing 32. When the head rotates smoothly, the first rib 121 will not come into contact with the second rib 321 due to the clearance between the second rib 321 and the first rib 121, thus ensuring smooth rotation of the head and reducing jamming. When the head swings, it causes the first bracket 1 and the first rib 121 on it to swing together, causing the first rib 121 to swing toward the second rib 321 and collide with it. The collision of the second rib 321 with the first rib 121 restricts the first bracket 1 and the head from continuing to swing, thereby limiting the swing of the head and improving the stability of the air outlet angle adjustment process.
[0057] It should be noted that the fit clearance between the second rib 321 and the first rib 121 should be as small as possible to ensure smooth rotation of the machine head while also preventing excessive swaying and improving stability. For example, the clearance between the second rib 321 and the first rib 121 can be 1mm, but it is not limited to this.
[0058] like Figure 6 As shown, in this embodiment, the first rib 121 and the second rib 321 are at the same horizontal height and are spaced apart, but this is not a limitation. For example, in other embodiments, the first rib 121 and the second rib 321 may also be arranged vertically at intervals.
[0059] In some embodiments, at least one of the first rib 121 and the second rib 321 extends along the rotation direction of the shaft 31.
[0060] By extending at least one of the first rib 121 and the second rib 321 along the rotation direction of the rotating shaft 31, when the rotating shaft 31 rotates and causes the first rib 121 to rotate relative to the second rib 321, at least a portion of the first rib 121 and the second rib 321 can remain opposite each other, thereby achieving a stop limit during swinging.
[0061] Preferably, at least one of the first rib 121 and the second rib 321 is configured as an annular shape.
[0062] By setting at least one of the first rib 121 and the second rib 321 as an annular shape, when the machine head swings in any direction such as left, right, or forward or backward, the machine head can be limited by the abutting cooperation of the first rib 121 and the second rib 321, thereby limiting the multi-directional swing of the machine head and ensuring the stability of the machine head rotation process.
[0063] In the embodiment, the first protruding rib 121 is arranged in a ring shape around the circumferential direction of the shaft sleeve 32, so that the first protruding rib 121 and the second protruding rib 321 can always maintain a matching relationship.
[0064] Of course, as an alternative embodiment, the first protruding rib 121 and the second protruding rib 321 can both be arranged in a ring shape, or only the second protruding rib 321 is arranged in a ring shape, and the same effect as the embodiment can be achieved.
[0065] In other embodiments, at least one of the first protruding rib 121 and the second protruding rib 321 is arranged in multiple around the circumferential direction of the shaft sleeve 32.
[0066] By arranging at least one of the first protruding rib 121 and the second protruding rib 321 in multiple around the circumferential direction of the shaft sleeve 32, the abutting matching range of the first protruding rib 121 and the second protruding rib 321 in the circumferential direction can be improved, and the swing limiting of the machine head in multiple directions in the circumferential direction can be achieved.
[0067] In the embodiment, the second protruding rib 321 is arranged in multiple around the circumferential direction of the shaft sleeve 32, and at least one second protruding rib 321 can always abut and match with the first protruding rib 121 during the rotation of the ring-shaped first protruding rib 121, so as to achieve the swing limiting of the machine head.
[0068] Of course, in other alternative embodiments, the first protruding rib 121 and the second protruding rib 321 can both be arranged in multiple around the circumferential direction of the shaft sleeve 32, and at least one first protruding rib 121 can abut and match with at least one second protruding rib 321 when multiple first protruding ribs 121 rotate to different positions, so as to achieve the swing limiting. Or the second protruding rib 321 is arranged in a ring shape, and the first protruding rib 121 is arranged in multiple around the circumferential direction of the shaft sleeve 32, and the above-mentioned effect can also be achieved.
[0069] As shown in FIGS. Figure 2 and Figure 6 In some embodiments, the shaft sleeve 32 is sleeved in the second support 2, the second support 2 is provided with a limiting clamping port 211, the second protruding rib 321 is clamped in the limiting clamping port 211, and the first protruding rib 121 matches with the second protruding rib 321 through the limiting clamping port 211.
[0070] By arranging the limiting clamping port 211 on the second support 2 and clamping the second protruding rib 321 in the limiting clamping port 211, the limiting between the shaft sleeve 32 and the second support 2 can be further achieved, so as to avoid the relative rotation between the shaft sleeve 32 and the second support 2, and ensure the stability and reliability of the matching between the shaft sleeve 32 and the second support 2.
[0071] In the embodiment, the plurality of limiting sockets 211 are provided, and the plurality of second protrusions 321 and the plurality of limiting sockets 211 are one-to-one correspondingly clamped, so as to enhance the limiting strength between the shaft sleeve 32 and the second support 2, and when one or part of the second protrusions 321 fails, the limiting can be realized through the cooperation of the remaining second protrusions 321 and the limiting sockets 211.
[0072] Further, in order to enhance the reliability of the connection between the shaft sleeve 32 and the second support 2, in some embodiments, the support structure further comprises a fastener (not shown in the figure), and the fastener is fixedly connected with the second support 2 and the shaft sleeve 32.
[0073] The provided fastener is used for fixedly connecting the second support 2 and the shaft sleeve 32, and can further enhance the connection strength between the second support 2 and the shaft sleeve 32.
[0074] In the embodiment, the fixed connection between the second support 2 and the shaft sleeve 32 through the fastener and the clamping cooperation of the second protrusions 321 and the limiting sockets 211 jointly realize the reliable connection between the second support 2 and the shaft sleeve 32.
[0075] For example, the fastener can be a screw, a bolt or a pin shaft, which can play a connecting and fixing structure, and the embodiment does not make specific limitation.
[0076] As shown in Figure 2 , Figure 5 , and Figure 6 , in some embodiments, the air outlet device comprises a head, the first support 1 comprises a first shell 11 and a second shell 12, wherein the first shell 11 is fixedly connected with the head and the rotating shaft 31, the second shell 12 is fixedly connected with the first shell 11, and the first protrusion 121 is arranged on the inner wall of the second shell 12.
[0077] The forms of the first shell 11 and the second shell 12 can realize the connection and support of the head, and can realize the surrounding arrangement of the rotating assembly 3, so as to avoid the structure exposed and increase the aesthetic property.
[0078] In terms of shape, the first shell 11 is in U shape, the head is arranged in the U-shaped groove of the first shell 11, and is fixedly connected with the two side walls of the U-shaped first shell 11. In order to facilitate disassembly and assembly, the head can be detachably fixed to the first shell 11.
[0079] The second shell 12 is in Y shape, the top outer contour of the second shell 12 matches the outer contour of the first shell 11, and the bottom cover of the second shell 12 is arranged outside the shaft sleeve 32.
[0080] In some embodiments, the support structure further comprises a rotating connecting piece, and the rotating shaft 31 is rotatably connected to the shaft sleeve 32 through the rotating connecting piece.
[0081] The rotation connecting piece is arranged to realize the rotatable connection between the rotating shaft 31 and the shaft sleeve 32, and avoid the disconnection between the rotating shaft 31 and the shaft sleeve 32.
[0082] As shown in Figure 3 , Figure 5 and Figure 7 , in some embodiments, the rotation connecting piece comprises a sliding groove 3111 and a protrusion 322, the sliding groove 3111 extends along the rotating direction of the rotating shaft 31, one of the sliding groove 3111 and the protrusion 322 is arranged on the outer wall of the rotating shaft 31, and the other is arranged on the inner wall of the shaft sleeve 32, and the protrusion 322 is rotatably connected to the sliding groove 3111.
[0083] When the rotating shaft 31 rotates relative to the shaft sleeve 32, the protrusion 322 adaptively slides along the sliding groove 3111, and the cooperation between the protrusion 322 and the sliding groove 3111 can limit the rotating shaft 31 from disengaging from the shaft sleeve 32, and at the same time, the cooperation between the protrusion 322 and the sliding groove 3111 can also support the rotation of the rotating shaft 31, thereby improving the rotation stability, and the assembly is simple and does not need to be fixed by screws, which is convenient and fast.
[0084] As an alternative embodiment, the rotation connecting piece can also be a bearing, and the rotatable connection between the rotating shaft 31 and the shaft sleeve 32 can also be realized through the bearing.
[0085] In this embodiment, the sliding groove 3111 is arranged on the outer wall of the rotating shaft 31, and the protrusion 322 is arranged on the inner wall of the shaft sleeve 32, but it is not limited thereto. As an alternative embodiment, the sliding groove 3111 can also be arranged on the inner wall of the shaft sleeve 32, and the protrusion 322 can also be arranged on the outer wall of the rotating shaft 31.
[0086] Preferably, the protrusion 322 can be arranged in two and symmetrically arranged on the left and right sides, which can not only enhance the limiting strength between the rotating shaft 31 and the shaft sleeve 32, but also make the force between the rotating shaft 31 and the shaft sleeve 32 more balanced, and be more conducive to the rotation stability of the rotating shaft 31.
[0087] Of course, in other embodiments, the number of protrusions 322 can be arranged as needed, for example, the protrusion 322 is also arranged in three, four, etc., and is not limited to this embodiment.
[0088] As shown in Figure 3 , in some embodiments, the sliding groove 3111 is arranged in a ring shape.
[0089] The ring-shaped sliding groove 3111 allows the protrusion 322 to rotate 360° along the sliding groove 3111, and thus the rotating shaft 31 can rotate 360° relative to the shaft sleeve 32, thereby expanding the rotation angle adjustment range of the machine head.
[0090] Of course, in other embodiments, the slide 3111 can also be set with a corresponding length along the circumference of the rotating shaft 31 according to the angle adjustment range of the machine head. For example, if the angle adjustment range of the machine head is 180°, then setting the slide 3111 to half the circumference along the rotating shaft 31 is sufficient to meet the rotation requirements.
[0091] like Figure 1 As shown, in some embodiments, the support structure further includes a drive component 4, which is connected to the rotating shaft 31 and is used to drive the rotating shaft 31 to rotate relative to the bushing 32 to a preset position.
[0092] The set drive component 4 can drive the rotating shaft 31 to rotate autonomously relative to the bushing 32 to a preset position without manual operation by the user, making it convenient to use and improve the user experience.
[0093] It should be noted that the preset position can be designed according to needs, and this embodiment does not impose any restrictions. For example, the preset position can be a position offset from the original position by 30°, 60°, or 90°.
[0094] like Figure 1 and Figure 2 As shown, in some embodiments, the drive assembly 4 includes a motor 41 and a transmission component. The motor 41 and the rotating shaft 31 are fixedly connected. The transmission component includes a drive gear 42 and a driven gear 43. The drive gear 42 is connected to the motor shaft 411 of the motor 41. The driven gear 43 is disposed on the bushing 32. The drive gear 42 and the driven gear 43 mesh. The motor 41 drives the drive gear 42 to rotate along the gear ring of the driven gear 43, thereby driving the rotating shaft 31, which is fixedly connected to the motor 41, to rotate relative to the bushing 32 to a preset position.
[0095] When the air outlet needs to adjust its angle, the motor 41 drives the drive gear 42 to rotate along the gear ring of the driven gear 43 via the motor shaft 411. This causes the rotating shaft 31, which is fixedly connected to the motor 41, to rotate relative to the bushing 32. Consequently, the first bracket 1 connected to the rotating shaft 31 and the head unit connected to the first bracket 1 rotate synchronously to the preset position, thus achieving the adjustment of the head unit's angle. Furthermore, the use of a motor 41 to drive the gear structure (the engagement of the drive gear 42 and the driven gear 43) increases the oscillation torque, solving the problem of insufficient oscillation torque causing the head unit to jam during rotation.
[0096] As an alternative implementation, the drive assembly 4 can also be configured such that the motor 41 directly drives the rotating shaft 31 to rotate, or the drive assembly 4 can also be configured such that the motor 41 drives the transmission chain to rotate, and the transmission chain cooperates with the sprocket on the rotating shaft 31 to drive the rotating shaft 31 to rotate.
[0097] In the embodiment, the motor 41 can rotate clockwise and counterclockwise to drive the rotating shaft 31 to rotate clockwise or counterclockwise, thereby driving the head to rotate clockwise or counterclockwise, and realizing the multi-angle adjustment requirement. For example, the motor 41 can be a stepping motor according to the requirement, but is not limited thereto.
[0098] As shown in Figure 2 In some embodiments, the rotating shaft 31 includes a shaft body 311 and a connecting portion 312, the shaft body 311 is rotatably sleeved in the shaft sleeve 32, the connecting portion 312 is fixedly connected with the rotating shaft 31, the connecting portion 312 is located above the shaft sleeve 32, the motor 41 is arranged on the connecting portion 312 and the motor shaft 411 passes through the connecting portion 312, and the driving gear 42 is arranged below the connecting portion 312.
[0099] The rotating shaft 31 is arranged in the form of the shaft body 311 and the connecting portion 312, the shaft body 311 is convenient for connection and cooperation with the shaft sleeve 32, and the connecting portion 312 is convenient for mounting and fixing of the motor 41, so that the cooperation between structures is realized.
[0100] Specifically, the connecting portion 312 is fixedly connected with the first shell 11, an installation cavity is formed between the connecting portion 312 and the first shell 11, the connecting portion 312 is provided with a through hole communicating with the installation cavity, the motor 41 is installed in the installation cavity, and the motor shaft 411 of the motor 41 passes through the through hole and is connected with the driving gear 42 below the connecting portion 312.
[0101] Specifically, the driven gear 43 is sleeved on the outer periphery of the shaft sleeve 32 and located at the top of the shaft sleeve 32. In the embodiment, considering the angle adjustment range of the head, the gear ring of the driven gear 43 is not arranged in a whole circle, but is arranged in an arc segment according to the angle adjustment range of the head. Of course, in other embodiments, the gear ring of the driven gear 43 can also be arranged in a whole circle.
[0102] As shown in Figure 1 and Figure 2 In some embodiments, the second support 2 includes a body support 21 and a support pipe 22, the body support 21 is connected and cooperated with the shaft sleeve 32, a limiting clamping port 211 is arranged on the body support 21, the support pipe 22 is sleeved on the outer periphery of the body support 21, plays a wrapping protection role, and improves the overall aesthetic property.
[0103] The accommodating cavity is formed between the first shell 11, the second shell 12 and the support pipe 22.
[0104] The second aspect of the utility model provides an air outlet device, including head and the utility model's support structure, first support 1 of support structure and head fixed connection.
[0105] Since the air outlet device of this utility model includes the support structure of this utility model, the air outlet device of this utility model has the same technical effect as the support structure, and will not be described in detail here.
[0106] In some embodiments, the air outlet is a fan.
[0107] Of course, the air outlet device can also be an air purifier, a heater, etc., and is not limited to this embodiment.
[0108] To facilitate understanding of the support structure and air outlet device in this embodiment, their usage process is described below:
[0109] When the air outlet needs to adjust the air outlet angle, the motor 41 drives the drive gear 42 to rotate along the gear ring of the driven gear 43 through the motor shaft 411, thereby driving the rotating shaft 31, which is fixedly connected to the motor 41, to rotate relative to the bushing 32. This, in turn, drives the first outer shell 11 connected to the rotating shaft 31, as well as the head and the second outer shell 12 connected to the first outer shell 11, to rotate synchronously to the preset position, ultimately achieving the adjustment of the head angle.
[0110] When the machine head rotates smoothly, the second rib 321 and the first rib 121 maintain a clearance fit to ensure smooth rotation of the machine head and reduce jamming.
[0111] When the air head swings / shakes (left / right / forward / backward), the air head causes the first outer shell 11 and the second outer shell 12 to swing as a whole. This causes the first rib 121 on the second outer shell 12 to swing toward the second rib 321 and collide with the second rib 321. The collision between the second rib 321 and the first rib 121 restricts the second outer shell 12, the first outer shell 11 and the air head from continuing to swing, thereby limiting the swing of the air head and improving the stability during the adjustment of the air outlet angle.
[0112] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
