[0061] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0062] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0063] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0064] At present, most of the air outlet equipment realizes air supply at different angles by controlling the swing blades. Most of the existing swing blades adopt the wind guiding method combining horizontal swing blades and vertical swing blades. The swing blades are greatly restricted by space and have limited swing angles, and cannot realize multi-angle air outlet.

[0065] In order to solve the above problems, the utility model proposes an air outlet frame module, aiming to achieve multi-angle air outlet.

[0066] See also Figure 1 , Figure 2 In one embodiment of the utility model, the air outlet frame module 100 includes an air outlet frame 10, a multi-link mechanism 20 and a swing blade 30; the multi-link mechanism 20 is arranged on the air outlet frame 10; one end of the swing blade 30 is rotatably connected to the air outlet frame 10, and the other end of the swing blade 30 is transmission-connected to the multi-link mechanism 20; wherein, the center of one end of the swing blade 30 rotatably connected to the air outlet frame 10 is defined as the rotation axis of the swing blade 30, the multi-link mechanism 20 drives the swing blade 30 to perform circular motion along the rotation axis, and the swing blade 30 is provided with an air outlet surface 312a, and the air outlet surface 312a is arranged at an angle to the rotation axis of the swing blade 30.

[0067] The technical solution of the utility model is to connect one end of the pendulum blade 30 to the air outlet frame 10 through rotation, and transmit the other end of the pendulum blade 30 to the multi-link mechanism 20. The pendulum blade 30 can be driven by the multi-link mechanism 20 to make circular motion along the center of one end of the pendulum blade 30 that is rotatably connected to the air outlet frame 10 as the rotation axis. Therefore, only one-way horizontal pendulum blades 30 or vertical pendulum blades 30 are needed, and the pendulum blades 30 are less restricted by space. In addition, since the air outlet surface 312a of the pendulum blade 30 is set at an angle to the rotation axis of the pendulum blade 30, the direction of the air outlet surface 312a can be changed during the circular motion of the pendulum blade 30, thereby achieving multi-angle air outlet.

[0068] In this embodiment, when the swing blade 30 is driven to make a circular motion by the multi-link mechanism 20, the swing blade 30 can be controlled to stay at any position on the circular path, so that air can be discharged in a specified direction.

[0069] See also Figures 3 to 8 When the swing blade 30 is driven by the multi-link mechanism 20 to make a circular motion and stay at the first position, the air outlet surface 312a of the swing blade 30 is tilted upward. At this time, the air outlet device 1000 using the air outlet frame module 100 will discharge air in an obliquely upward direction.

[0070] See also Figures 9 to 11 When the swing blade 30 is driven by the multi-link mechanism 20 to make a circular motion and stay at the second position, the air outlet surface 312a of the swing blade 30 is tilted to the left. At this time, the air outlet device 1000 using the air outlet frame module 100 will discharge air in a direction obliquely to the left.

[0071] See also Figures 12 to 15 When the swing blade 30 is driven by the multi-link mechanism 20 to make a circular motion and stay at the third position, the air outlet surface 312a of the swing blade 30 is tilted downward. At this time, the air outlet device 1000 using the air outlet frame module 100 will discharge air in an obliquely downward direction.

[0072] See also Figures 16 to 18 When the swing blade 30 is driven by the multi-link mechanism 20 to make a circular motion and stay at the fourth position, the air outlet surface 312a of the swing blade 30 is tilted to the right. At this time, the air outlet device 1000 using the air outlet frame module 100 will discharge air in a direction obliquely to the right.

[0073] It should be noted that up, down, left and right refer to the four directions when the air outlet frame module 100 faces the user. Of course, in addition to the air outlet in the above four directions, the swing blade 30 can also be driven by the multi-link mechanism 20 to make a circular motion and stay in other positions to achieve air outlet in other directions.

[0074] As some exemplary examples, the angle between the air outlet surface 312a of the pendulum blade 30 and the rotation axis of the pendulum blade 30 can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., which can be determined according to actual usage.

[0075] See also Figure 2 , Figure 4 , Figure 7In one embodiment of the utility model, the multi-link mechanism 20 includes a driving member 21 and a multi-link assembly 22; the driving member 21 is arranged on the air outlet frame 10; the multi-link assembly 22 is transmission-connected to the driving member 21, and the driving member 21 drives the multi-link assembly 22 to make a circular motion or swing along the output shaft 211 of the driving member 21; the end of the swing blade 30 away from the air outlet frame 10 is rotationally connected to the multi-link assembly 22, and the multi-link assembly 22 drives the swing arm to make a circular motion along the rotation axis under the circular motion or swinging.

[0076] With such a configuration, the driving member 21 can work and drive the multi-link assembly 22 to make circular motion or swing along the output shaft 211 of the driving member 21. The multi-link assembly 22 can drive the rocker arm to make circular motion along the rotation axis under the circular motion or swinging. In this way, the multi-link assembly 22 can drive the rocker arm to make circular motion more smoothly in the form of circular motion or swinging, thereby avoiding shaking, swaying, etc. of the rocker blade 30 during the movement, thereby reducing the generation of noise.

[0077] In actual application, the driving member 21 can be a rotating motor to directly drive the multi-link assembly 22 to perform circular motion or swing through the output shaft 211 of the rotating motor; or, the driving member 21 can also be a structure in which a linear motor and a rack and pinion cooperate. When the linear motor drives the rack to move, the rack can drive the gear to rotate, and the gear has an output shaft 211, so as to drive the multi-link assembly 22 to perform circular motion or swing through the output shaft 211 of the gear; or, the driving member 21 can also be a structure in which a rotating motor and a gear set cooperate. The gear set can include a first gear and a second gear that are meshed with each other. When the rotating motor drives the first gear to rotate, the first gear can drive the second gear to rotate, and the second gear has an output shaft 211, so as to drive the multi-link assembly 22 to perform circular motion or swing through the output shaft 211 of the second gear.

[0078] Of course, in other embodiments, the multi-link assembly 22 can also be driven by the driving member 21 to rotate along the rotation axis of the swing blade 30, which can also drive the swing rod to perform circular motion along the rotation axis.

[0079] See also Figure 2 In one embodiment of the utility model, the multi-link assembly 22 includes at least two driving links 221 and a swing blade link 222; at least two driving members 21 are provided, each driving member 21 drives a driving link 221 to make a circular motion; the swing blade link 222 is rotatably connected to at least two driving links 221 to swing with the circular motion of the driving link 221; the end of the swing blade 30 away from the air outlet frame 10 is rotatably connected to the swing blade link 222.

[0080] In this arrangement, at least two driving members 21 work synchronously to drive at least two driving links 221 to make circular motion along the output shaft 211 of the driving member 21 connected thereto, thereby driving the swing blade link 222 to swing smoothly along the circular motion of the driving link 221, thereby driving the swing blade 30 to make circular motion under the movement of the swing blade link 222. Since at least two driving links 221 are used to synchronously drive the swing blade link 222 to swing, the stability of the swing blade link 222 during the movement can be guaranteed to prevent the end of the swing blade link 222 from tilting and affecting the stability of the movement of the driving swing blade 30.

[0081] As some exemplary examples, the driving connecting rods 221 may be provided with two, three, four, etc., which may be determined according to actual usage. Of course, in some embodiments, two driving connecting rods 221 may be provided to reduce costs.

[0082] In actual application, the driving connecting rod 221 can be rotatably connected to the end of the swing blade connecting rod 222, or to the middle of the swing blade connecting rod 222, or to other positions of the swing blade connecting rod 222, depending on the actual usage.

[0083] In actual application, the rotational force arm of the swing blade 30 may be equal to or unequal to the rotational force arm of the driving connecting rod 221. In some embodiments, when the rotational force arm of the swing blade 30 is equal to the rotational force arm of the driving connecting rod 221, the swing blade 30 may be directly connected to the swing blade connecting rod 222 for rotation; in other embodiments, when the rotational force arm of the swing blade 30 is unequal to the rotational force arm of the driving connecting rod 221, the swing blade 30 may be connected to the swing blade connecting rod 222 for rotation through an elastic member, so that the swing blade 30 may be driven to perform circular motion under the deformation of the elastic member and the swing of the swing blade connecting rod 222.

[0084] See also Figure 7 , Figure 8 In one embodiment of the present invention, the rotational force arm of the swing blade 30 is equal to the rotational force arm of the driving connecting rod 221.

[0085] Such an arrangement can make the swing blade 30 and the driving connecting rod 221 maintain synchronization during the circular motion, and can improve the stability of the swing blade 30 during the circular motion.

[0086] It should be noted that the rotational force arm of the swing blade 30 refers to the vertical distance from the line of action of the force of the swing blade 30 to the rotation axis of the swing blade 30; the rotational force arm of the driving connecting rod 221 refers to the vertical distance from the line of action of the force of the driving connecting rod 221 to the output shaft 211.

[0087] See also Figure 7In one embodiment of the utility model, the driving connecting rod 221 includes a rod body 2211, a first connecting shaft 2212 and a second connecting shaft 2213; the first connecting shaft 2212 is connected to one end of the rod body 2211 and is transmission-connected to the driving member 21; the second connecting shaft 2213 is connected to the other end of the rod body 2211 and is rotationally connected to the swing leaf connecting rod 222, and the first connecting shaft 2212 and the second connecting shaft 2213 are respectively arranged on two sides of the rod body 2211 facing each other.

[0088] With such arrangement, by using the first connecting shaft 2212 to be transmission-connected with the driving member 21, it is easier to realize the connection between the driving link 221 and the driving member 21. Similarly, by using the second connecting shaft 2213 to be rotationally connected with the swing blade link 222, it is also easier to realize the connection between the driving link 221 and the swing blade link 222. In addition, by arranging the first connecting shaft 2212 and the second connecting shaft 2213 on two sides opposite to each other of the rod body 2211, the swing blade link 222 and the driving member 21 can be respectively installed on two sides opposite to each other of the rod body 2211. This not only makes the overall structure more compact, but also avoids the driving member 21 and the swing blade link 222 being installed on the same side of the rod body 2211, which affects the circular motion of the swing blade link 222.

[0089] As some examples, the first connecting shaft 2212 and the second connecting shaft 2213 can be an integrally formed structure with the rod body 2211, which can not only ensure the connection strength between the first connecting shaft 2212 and the second connecting shaft 2213 and the rod body 2211, but also simplify the preparation process. Of course, in other embodiments, the first connecting shaft 2212 and the second connecting shaft 2213 can also be fixedly connected to the rod body 2211 by bonding, screw connection, clamping, etc.

[0090] See also Figure 2 , Figure 7 In one embodiment of the utility model, a first axial hole (not shown) is provided at the end of the first connecting shaft 2212 away from the rod body 2211, and the output shaft 211 of the driving member 21 can be inserted into the first axial hole, so that under the cooperation between the output shaft 211 and the first axial hole, the driving connecting rod 221 can be smoothly driven by the driving member 21 to perform circular motion.

[0091] In some embodiments, in order to prevent relative rotation between the output shaft 211 of the driving member 21 and the first connecting shaft 2212, a limiting protrusion can be provided on one of the outer wall of the output shaft 211 and the inner wall of the first shaft hole, and a limiting groove can be provided on the other one, so that the output shaft 211 and the first connecting shaft 2212 can be limited by the cooperation of the limiting protrusion and the limiting groove, so that the output shaft 211 can smoothly drive the driving connecting rod 221 to make a circular motion.

[0092] See also Figure 4 In one embodiment of the utility model, the swing blade connecting rod 222 is provided with a second shaft hole 2221, and the second connecting shaft 2213 is rotatably connected to the second shaft hole 2221, so that the swing blade connecting rod 222 and the driving connecting rod 221 are hinged under the cooperation of the second connecting shaft 2213 and the second shaft hole 2221.

[0093] In some embodiments, since the width of the swing blade connecting rod 222 is relatively small, in order to prevent the swing blade connecting rod 222 from bending, breaking, etc. at the position where the second axial hole 2221 is opened, the outer side of the second axial hole 2221 can be widened to ensure the strength of the swing blade connecting rod 222.

[0094] In some embodiments, in order to ensure the installation stability between the second connecting shaft 2213 and the second shaft hole 2221, so as to prevent the second connecting shaft 2213 from falling out of the second shaft hole 2221 during operation, a first limit member can be provided at the end of the second connecting shaft 2213 away from the rod body 2211, and the outer contour size of the first limit member is larger than the aperture of the second shaft hole 2221, so that the first limit member abuts against the side surface of the swing blade connecting rod 222 away from the rod body 2211.

[0095] Furthermore, in order to allow the first limit member to pass through the second axial hole 2221 smoothly, the first limit member can include two first limit blocks that are relatively arranged, and a first deformation avoidance groove is formed between the two first limit blocks. In this way, during the installation process, the end of the second connecting shaft 2213 provided with the first limit member can be passed toward the second axial hole 2221. During this process, the two first limit blocks will be squeezed and moved closer to the first deformation avoidance groove to reduce the outer contour size of the first limit member until the first limit member passes through the second axial hole 2221 smoothly. After passing through the second axial hole 2221, the two first limit blocks are reset to complete the installation.

[0096] See also Figure 2 In one embodiment of the present invention, at least two driving connecting rods 221 are respectively disposed at two ends of the swing blade connecting rod 222 .

[0097] Such an arrangement can prevent the driving connecting rod 221 from occupying the position between the two ends of the swing blade connecting rod 222, so that the swing blade 30 can be installed between the two ends of the swing blade connecting rod 222, and as many swing blades 30 as possible can be installed to ensure the air outlet area.

[0098] In actual application, one or at least two driving connecting rods 221 may be rotatably connected to the end of the swing blade connecting rod 222 .

[0099] See also Figure 1 , Figure 2In one embodiment of the utility model, the swing blade connecting rod 222 is extended along the length direction of the air outlet frame 10 , and a plurality of swing blades 30 are spaced apart and distributed along the length direction of the swing blade connecting rod 222 .

[0100] In this configuration, by distributing a plurality of swing blades 30 at intervals in the length direction of the swing blade connecting rod 222 , the airflow can be more smoothly guided to a designated direction through the plurality of swing blades 30 , so as to improve the air outlet effect.

[0101] In actual application, the intervals between any two adjacent swing blades 30 may be the same or different.

[0102] See also Figure 8 In one embodiment of the utility model, the swing blade 30 includes a swing blade body 31, a third connecting shaft 32 and a fourth connecting shaft 33; the third connecting shaft 32 is connected to one side of the swing blade body 31 and is rotatably connected to the air outlet frame 10; the fourth connecting shaft 33 is connected to the other side of the swing blade body 31 and is rotatably connected to the multi-link mechanism 20.

[0103] With such arrangement, by using the third connecting shaft 32 to connect with the air outlet frame 10, it is easier to achieve the connection between the swing blade 30 and the air outlet frame 10. Similarly, by using the fourth connecting shaft 33 to rotatably connect with the multi-link mechanism 20, it is also easier to achieve the connection between the swing blade 30 and the multi-link mechanism 20.

[0104] As some examples, the third connecting shaft 32 and the fourth connecting shaft 33 can be an integrally formed structure with the swing blade body 31, which can not only ensure the connection strength between the third connecting shaft 32 and the fourth connecting shaft 33 and the swing blade body 31, but also simplify the preparation process. Of course, in other embodiments, the third connecting shaft 32 and the fourth connecting shaft 33 can also be fixedly connected to the swing blade body 31 by bonding, screw connection, clamping, etc.

[0105] See also Figure 2 , Figure 8 In one embodiment of the utility model, the air outlet frame 10 is provided with a third shaft hole 11, and the third connecting shaft 32 is rotatably connected to the third shaft hole 11, so that the rotational connection between the swing blade 30 and the air outlet frame 10 is realized under the cooperation of the third connecting shaft 32 and the third shaft hole 11.

[0106] See also Figure 5 In one embodiment of the utility model, the multi-link mechanism 20 is provided with a fourth shaft hole 2222, and the fourth connecting shaft 33 is rotatably connected to the fourth shaft hole 2222, so that the swing blade 30 and the multi-link mechanism 20 are hinged under the cooperation of the fourth connecting shaft 33 and the fourth shaft hole 2222.

[0107] In some embodiments, the fourth axial hole 2222 is arranged on the swing blade link 222 of the multi-link mechanism 20. Since the width of the swing blade link 222 is relatively small, in order to avoid bending, breaking, etc. of the swing blade link 222 at the position where the fourth axial hole 2222 is opened, the outer side of the fourth axial hole 2222 can be widened to ensure the strength of the swing blade link 222.

[0108] In some embodiments, in order to ensure the installation stability between the fourth connecting shaft 33 and the fourth shaft hole 2222, so as to prevent the fourth connecting shaft 33 from falling out of the fourth shaft hole 2222 during operation, a second limit member can be provided at the end of the fourth connecting shaft 33 away from the swing blade body 31, and the outer contour size of the second limit member is larger than the aperture of the fourth shaft hole 2222, so that the second limit member abuts against the side surface of the swing blade connecting rod 222 away from the swing blade body 31.

[0109] Furthermore, in order to allow the second limit member to pass through the fourth axial hole 2222 smoothly, the second limit member can include two second limit blocks that are relatively arranged, and a second deformation avoidance groove is formed between the two second limit blocks. In this way, during the installation process, the end of the fourth connecting shaft 33 provided with the second limit member can be passed toward the fourth axial hole 2222. During this process, the two second limit blocks will be squeezed and moved closer to the second deformation avoidance groove to reduce the outer contour size of the second limit member until the second limit member passes through the fourth axial hole 2222 smoothly. After passing through the fourth axial hole 2222, the two second limit blocks are reset to complete the installation.

[0110] See also Figure 8 In one embodiment of the utility model, the swing blade body 31 includes an air guide portion 311 and an air outlet portion 312; the third connecting shaft 32 is connected to one side of the air guide portion 311, and the air guide portion 311 is provided with an air guide surface 311a, and the air guide surface 311a is arranged parallel to the axis of the rotating shaft of the swing blade 30; the air outlet portion 312 is connected to the side of the air guide portion 311 away from the third connecting shaft 32, and is provided with an air outlet surface 312a, and the air outlet surface 312a is arranged at an angle with the air guide surface 311a, and the fourth connecting shaft 33 is connected to the side of the air outlet portion 312 away from the air guide portion 311.

[0111] In this way, by making the guide surface of the air guide part 311 parallel to the rotation axis of the swing blade 30, the airflow can be smoothly guided to the air outlet surface 312a of the air outlet part 312 through the air guide surface 311a of the air guide part 311, and then the airflow can be guided to a specified direction through the air outlet surface 312a of the air outlet part 312, so as to achieve smooth air outlet in the specified direction.

[0112] As some examples, the air outlet 312 and the air guide 311 can be an integrally formed structure, which can not only ensure the connection strength between the air outlet 312 and the air guide 311, but also simplify the preparation process. Of course, in other embodiments, the air outlet 312 can also be fixedly connected to the air guide 311 by bonding, screw connection, clamping, etc.

[0113] See also Figure 8 In one embodiment of the utility model, the air outlet portion 312 includes a first air outlet piece 3121, a connecting member 3122 and a second air outlet piece 3123; the first air outlet piece 3121 is connected to one side of the air guide portion 311; the connecting member 3122 is connected to the first air outlet piece 3121; the second air outlet piece 3123 is connected to the connecting member 3122 and is arranged opposite to the first air outlet piece 3121, and the first air outlet piece 3121 and the second air outlet piece 3123 are both provided with an air outlet surface 312a.

[0114] In this way, the air outlet part 312 is provided with a first air outlet piece 3121 and a second air outlet piece 3123, so that the swing blade 30 has a double-layer swing blade 30 structure. In this way, the direction of the airflow can be guided simultaneously by the air outlet surface 312a of the first air outlet piece 3121 and the air outlet surface 312a of the second air outlet piece 3123 to improve the air outlet effect.

[0115] In some embodiments, the air guide portion 311 is provided with two air guide surfaces 311a disposed back to back, wherein one air guide surface 311a is used to guide the airflow toward the air outlet surface 312a of the first air outlet plate 3121 , and the other air guide surface 311a is used to guide the airflow toward the air outlet surface 312a of the second air outlet plate 3123 .

[0116] In actual application, the connecting member 3122 can be a connecting structural member in the shape of a plate, a rod, a tube, a block, etc.

[0117] In some embodiments, the connecting member 3122 is a plate-shaped connecting structure having two opposite sides, one side of the connecting member 3122 is connected to a side surface of the first air outlet plate 3121 , and the other side of the connecting member 3122 is connected to a side surface of the second air outlet plate 3123 .

[0118] See also Figure 8 In one embodiment of the present invention, the first air outlet plate 3121 and the second air outlet plate 3123 are arranged in parallel.

[0119] With such an arrangement, the air outlet surface 312a of the first air outlet plate 3121 and the air outlet surface 312a of the second air outlet plate 3123 can face the same direction, so that the airflow can be guided to the same direction through the air outlet surface 312a of the first air outlet plate 3121 and the air outlet surface 312a of the second air outlet plate 3123, which can further improve the air outlet effect.

[0120] In actual application, when the swing blade 30 is driven by the multi-link mechanism 20 to perform circular motion and stay in the first position, that is, when the air outlet surface 312a of the first air outlet plate 3121 and the air outlet surface 312a of the second air outlet plate 3123 are both inclined upward, the second air outlet plate 3123 can be located below the first air outlet plate 3121 or above the first air outlet plate 3121.

[0121] See also Figure 8 In one embodiment of the present utility model, the air outlet surface 312a of the first air outlet piece 3121 and the air guide surface 311a of the air guide portion 311 are in an arc transition.

[0122] With such arrangement and the use of an arc transition design, the airflow flowing through the air guide surface 311 a can flow more smoothly to the air outlet surface 312 a, thereby making the air guiding smoother.
