Description

Technical Field

[0001] The invention relates to automobile interior decoration, and in particular to an air outlet structure. Background Art

[0002] Cars have entered people's homes as a means of transportation. Car air conditioners, as car components, can improve the temperature inside the car and enhance the driving experience. The air outlet structure, as a part of the car air conditioner, is indispensable. It can change the direction and volume of air. The direction of air can be changed by operating the outer blades and inner blades; the air volume can be changed by operating the damper.

[0003] Currently, there are two control mechanisms for the air outlet structure with air dampers on the market: a dial mechanism for controlling the rotation of the inner and outer blades and a dial wheel or knob mechanism for controlling the opening and closing of the air damper. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides an air outlet structure which only requires one control mechanism to control the inner and outer blades and the air door.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An air outlet structure comprises an air outlet and a control structure for controlling the air outlet, wherein the air outlet comprises at least one outer blade rotatable about a first direction, at least one inner blade rotatable about a second direction, and a damper;

[0007] The control structure includes an operating member, which can be universally rotated and rotated around its own axis;

[0008] When the operating member is in a universally rotating state, the outer blades rotate around a first direction and / or the inner blades rotate around a second direction; when the operating member is in a rotating state around its own axis, the damper rotates.

[0009] With the above structure, the outer blades, the inner blades and the damper can be controlled by universal rotation and rotation of the operating member, so that a control mechanism can control the air outlet direction and air volume.

[0010] Specifically, when the operating member rotates around a specific direction in the universal rotation, the control structure only controls the rotation of the outer blades; when the operating member rotates around another specific direction in the universal rotation, the control structure only controls the rotation of the inner blades; when the operating member rotates around other directions in the universal rotation, the control structure controls both the rotation of the outer blades and the rotation of the inner blades.

[0011] The air outlet structure includes an air outlet shell having an air inlet side and an air outlet side, the outer blades are arranged near the air outlet side, the damper is arranged near the air inlet side, and the inner blades are arranged between the outer blades and the damper; the first direction is perpendicular to the second direction and the outer blades are horizontal blades, and the inner blades are vertical blades; for easy installation, the air outlet shell includes a first shell and a second shell.

[0012] Furthermore, the control structure includes a first rotating structure, the first transmission structure includes a driving member driven by the universal rotation of the operating member, and a swing arm driven to rotate by the driving member; the swing arm is connected to the outer wall of the driving member and the two can slide in at least two directions; the swing arm includes an outer blade swing arm for driving the outer blade and an inner blade swing arm for driving the inner blade.

[0013] By adopting the above structure, when the driving member drives the universal rotation to drive the swing arm to rotate, it can be ensured that the position of the swing arm does not shift and the control structure does not get stuck.

[0014] The position where the driving member is used to drive the swing arm is called the driving position. Taking the outer blade swing arm as an example, if the rotation axis of the driving member during universal rotation is always parallel to or coincides with the rotation axis of the outer blade swing arm, the driving position of the outer blade swing arm driven by the driving member will not be offset after the driving member rotates; however, when the rotation axis of the driving member during universal rotation is not parallel to or coincides with the axis of the rotation shaft of the outer blade swing arm or the axis of the rotation shaft changes when the driving member rotates, the driving position of the outer blade swing arm driven by the driving member will be offset after the driving member rotates; therefore, the above-mentioned structure is adopted, and the driving member can rotate around a certain axis at will. If the driving position of the outer blade swing arm is offset, the offset is completed by the sliding between the outer blade swing arm and the driving member.

[0015] If the sliding trajectories are the same or overlap, it is regarded as sliding in one direction, such as sliding to the left and sliding to the right in the same trajectory are regarded as sliding in the same direction; or if sliding in different parallel or concentric sliding paths actually slides to the left or right, the sliding trajectories overlap and are regarded as the same direction.

[0016] Furthermore, the swing arm is connected to the driving member via a swing arm shaft, the swing arm shaft is slidably connected to the swing arm and the driving member, and the sliding direction between the swing arm shaft and the swing arm is different from the sliding direction between the swing arm shaft and the driving member.

[0017] With the above structure, a swing arm shaft is arranged between the driving member and the swing arm, which can ensure that the driving member can drive the swing arm to rotate and can also achieve sliding in two directions between the two.

[0018] The swing arm rotating shaft includes an outer blade swing arm rotating shaft matched with the outer blade swing arm, and an inner blade swing arm rotating shaft matched with the inner blade swing arm.

[0019] Furthermore, a first slide groove is provided on the side of the swing arm shaft facing the driving member, and a second slide bar is provided on the side of the swing arm; correspondingly, a first slide bar matching the first slide groove is provided on the outer wall of the driving member, and a second slide groove matching the second slide bar is provided on the shaft portion of the swing arm; the setting directions of the first slide groove and the second slide bar are cross-shaped.

[0020] By adopting the above structure, the swing arm shaft can slide more smoothly between the swing arm and the driving member.

[0021] Furthermore, the rotation axis of the outer blade swing arm is perpendicular to the rotation axis of the inner blade swing arm.

[0022] When the first slide groove and the second slide bar arranged on the swing arm shaft are in a cross-shaped state, the above structure is adopted, and when the rotation axis of the driving member is parallel to or coincides with the rotation axis of the outer blade swing arm shaft, the first slide bar on the driving member that matches the outer blade swing arm shaft rotates to drive the outer blade swing arm shaft to rotate; the first slide bar on the driving member that matches the inner blade swing arm shaft slides in the first slide groove in the inner blade swing arm shaft, and the first slide bar on the driving member that matches the inner blade swing arm shaft does not rotate, that is, the driving member does not rotate the inner blade swing arm shaft;

[0023] When the rotation axis of the driving member is parallel to or coincides with the rotation axis of the inner blade swing arm shaft, the first slide bar on the driving member that matches the inner blade swing arm shaft rotates to drive the inner blade swing arm shaft to rotate; the first slide bar on the driving member that matches the outer blade swing arm shaft slides in the first slide groove in the outer blade swing arm shaft, and the first slide bar on the driving member that matches the outer blade swing arm shaft does not rotate, that is, the driving member does not rotate the outer blade swing arm shaft; so as to realize the separate driving of the outer blade swing arm or the inner blade swing arm;

[0024] When the rotation axis of the driving member is not parallel or coincident with the rotation axis of the outer blade swing arm shaft and the inner blade swing arm shaft, the first slide bar on the driving member that matches the outer blade swing arm shaft and the inner blade swing arm shaft both rotate to drive the outer blade swing arm shaft and the inner blade swing arm shaft to rotate, and the first slide bar on the driving member that matches the outer blade swing arm shaft slides in the first slide groove on the outer blade swing arm shaft, and the second slide bar on the outer blade swing arm shaft slides in the second slide groove on the outer blade swing arm; the first slide bar on the driving member that matches the inner blade swing arm shaft slides in the first slide groove on the inner blade swing arm shaft, and the second slide bar on the inner blade swing arm shaft slides in the second slide groove on the inner blade swing arm, to avoid jamming of the swing arm shaft mechanism when the outer blade swing arm and the inner blade swing arm are not offset.

[0025] Furthermore, at least part of the outer wall of the driving member is an outwardly convex arc-shaped spherical surface, and correspondingly, at least part of the inner wall of the driving member is an inwardly concave arc-shaped spherical surface; the swing arm is connected to the outwardly convex arc-shaped spherical surface of the outer wall of the driving member.

[0026] With the above structure, the convex arc-shaped spherical surface of the driving member can make the universal rotation operation of the driving member more comfortable and smooth.

[0027] Furthermore, the first transmission structure includes an outer blade connecting rod and an inner blade connecting rod; one end of the outer blade connecting rod is connected to the outer blade swing arm ball head structure, and the other end is connected to an outer blade ball head structure in at least one outer blade; one end of the inner blade connecting rod is connected to the inner blade swing arm ball head structure, and the other end is connected to an inner blade ball head structure in at least one inner blade.

[0028] With the above structure, the two ends of the outer blade connecting rod and the inner blade connecting rod are connected by a ball head structure to avoid the outer blade swing arm and the inner blade swing arm from getting stuck when driving the outer blade and the inner blade, thereby ensuring stable and reliable operation of the control structure.

[0029] The inner blade comprises an inner blade body and an inner blade crank arranged at the rotating shaft of the inner blade body; one end of the inner blade connecting rod is connected to the inner blade crank ball head structure.

[0030] Further, the control structure includes a second transmission structure, which includes an operating member connecting member for connecting with the operating member, and a damper operating connecting member for operating and driving the damper, and the operating member connecting member is installed on the damper operating connecting member through a universal joint.

[0031] One end of the second transmission structure is used to drive the damper, that is, one end of the damper operating connecting member drives the damper, so the end driving the damper is inevitably subject to certain restrictions; therefore, the above structure is adopted, and the universal rotation of the operating member is realized through the universal joint between the operating member connecting member and the damper operating connecting member.

[0032] Specifically, the universal joint is a cross-axis universal joint, the universal joint is connected to the damper operating connecting piece via one of the rotating shafts, the operating connecting piece is connected to the other rotating shaft of the universal joint, and the two rotating shafts of the universal joint are perpendicular to each other.

[0033] With the above structure, the operating member connecting member can rotate relative to the damper connecting member around one of the rotating shafts of the universal joint, or around the other rotating shaft, or around two rotating shafts at the same time to realize the universal rotation of the driving member.

[0034] Furthermore, the second transmission structure includes a damper driven gear and a damper connecting rod connected to the damper; the damper operating connecting piece is used to drive the damper and is provided with a damper driving gear meshing with the damper driven gear at one end; the rotation axis of the damper driven gear forms an angle with the rotation axis of the damper driving gear; the non-rotating axis of the damper driven gear is connected to the ball head structure at one end of the damper connecting rod, and the other end of the damper connecting rod is connected to the damper ball head structure.

[0035] With the above structure, when the operating member rotates around its own axis, the rotation of the operating member drives the operating member connecting member, the universal joint, and the damper operating connecting member to rotate, so that the damper driving gear arranged at one end of the damper operating connecting member rotates and drives the damper driven gear meshing therewith to rotate, and the damper is driven to rotate by the damper connecting rod arranged between the damper driven gear and the damper, thereby realizing the control of the air output volume.

[0036] The connection between the two ends of the damper connecting rod and the damper driven gear and the damper adopts a ball head structure to avoid jamming between the damper driven gear, the damper connecting rod and the damper, thereby ensuring that the operating structure can operate stably and reliably.

[0037] Specifically, the damper operating connecting member comprises a damper operating member body, and a damper driving gear arranged at one end of the damper operating member body; the damper driving gear is provided with a connecting groove at the connection with the damper operating member body, and the groove wall of the connecting groove is symmetrically provided with groove openings; the damper operating member body is provided with a ball head matching the connecting groove at the end of the connecting section with the damper driving gear, and the ball head extends outwardly on one of the rotating shafts of the universal joint to have a connecting shaft matching the groove opening; when the ball head at one end of the damper operating member body is installed in the connecting groove of the damper driving gear, the connecting shaft is stuck in the groove opening;

[0038] When the damper operating member body rotates, the connecting shaft and the connecting groove cooperate with each other, so that the damper driving gear rotates together with the damper operating member body.

[0039] The cooperation between the connecting groove and the ball head reduces the restriction between the damper operating member body and the damper driving gear; the damper operating member body can rotate around the connecting shaft or make the two ends of the connecting shaft slide along the groove opening to achieve rotation around the connecting shaft perpendicular to the connecting shaft or combine the above two movement modes.

[0040] Specifically, the damper driven gear portion is provided with gear teeth, and a connecting rod connecting arm extends outward from the portion where the gear teeth are not provided, and one end of the damper connecting rod is connected to the connecting rod connecting arm ball head structure; the connecting rod connecting arm enhances the driving ability of the damper driven gear.

[0041] The damper driving gear and the damper driven gear are both bevel gears.

[0042] The damper comprises a damper body and a damper crank arranged at the damper body rotating shaft; one end of the damper connecting rod is connected to the damper crank ball head structure, and the connection between the damper connecting rod and the damper crank is not at the damper body rotating shaft.

[0043] The rotation axis of the damper driven gear forms an angle with the rotation axis of the damper driving gear, which can rotate the damper to the maximum extent. Specifically, the rotation axis of the damper driven gear is perpendicular to the rotation axis of the damper driving gear; the damper driven gear is rotatably mounted on the air outlet housing.

[0044] Furthermore, the air outlet structure includes a panel and a base for installing the control structure; the panel is provided with a first opening for exposing the operating member and at least part of the outer wall of the driving member; the panel and the base cooperate to form a cavity for installing the control structure.

[0045] The cavity is provided with a second opening and a third opening where the outer blade swing arm and the inner blade swing arm are provided. The second opening and the third opening are respectively used to engage the rotating shafts of the outer blade swing arm and the inner blade swing arm, thereby limiting the outer blade swing arm and the inner blade swing arm.

[0046] The cavity is provided with a gear mounting portion for mounting the damper driving gear, and a damping ring is provided between the mounting shaft of the damper driving gear and the gear mounting portion, so that a certain operating force is required to rotate the damper driving gear.

[0047] The cavity is provided with a damping block at the location where the driving member is installed, and the damping block is in contact with the outer wall of the driving member, so that a certain operating force is required to rotate the driving member.

[0048] Furthermore, the outer wall of the driving member protrudes outward to form a bump, and correspondingly, the inner wall of the cavity is recessed to form a bump groove matching the bump.

[0049] When the driving member rotates, the protrusion needs to slide along the protrusion slot. If the driving member rotates in a direction inconsistent with the sliding direction of the protrusion, when the protrusion slides in the protrusion slot, the protrusion slot will apply a force to the protrusion to make the driving member spin. At this time, the second slide bar of the swing arm shaft slides in the second slide bar of the rotating member to avoid the control structure from getting stuck. The protrusion and the protrusion slot can make the control structure run more stably. The protrusion and the protrusion slot can also be used for positioning. When the driving member rotates in the same direction as the sliding direction of the protrusion, the control structure is in a special situation. Generally, the protrusion position is located on the bisector of the line connecting the first slide bar matched with the outer blade swing arm shaft and the first slide bar matched with the inner blade swing arm shaft. At this time, when the driving member rotates in the same direction as the sliding direction of the protrusion, the driving member drives the outer blade swing arm shaft and the inner blade swing arm shaft at the same time, and the rotation amplitude of the outer blade swing arm shaft is the same as the rotation amplitude of the inner blade swing arm shaft.

[0050] Compared with the prior art, the present invention has the following beneficial effects:

[0051] (1) The air outlet structure of the present invention only requires one control mechanism to control the inner and outer blades and the damper.

[0052] (2) The air outlet structure of the present invention is reasonably designed and can effectively avoid the control structure from getting stuck.

[0053] (3) The special design between the driving member and the swing arm of the air outlet structure of the present invention can ensure that the position of the swing arm does not shift when the driving member rotates in all directions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0065] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0066] like Figure 1 As shown in FIG. 10 , an air outlet structure comprises an air outlet 1 and a control structure 2 for controlling the air outlet 1, wherein the air outlet 1 comprises at least one outer blade 101 rotatable about a first direction, at least one inner blade 102 rotatable about a second direction, and a damper 103;

[0067] The control structure 2 includes an operating member 201, and the operating member 201 can be universally rotated and rotated around its own axis;

[0068] When the operating member 201 is in a universally rotating state, the outer blades 101 rotate around a first direction and / or the inner blades 102 rotate around a second direction; when the operating member 201 rotates around its own axis, the damper 103 rotates.

[0069] With the above structure, the outer blades 101, the inner blades 102, and the damper 103 can be controlled by universal rotation and rotation of the operating member 201, so that a control mechanism can control the air outlet direction and air volume.

[0070] Specifically, when the operating member 201 rotates around a specific direction in the universal rotation, the control structure 2 only controls the rotation of the outer blade 101; when the operating member 201 rotates around another specific direction in the universal rotation, the control structure 2 only controls the rotation of the inner blade 102; when the operating member 201 rotates around other directions in the universal rotation, the control structure 2 controls the rotation of both the outer blade 101 and the inner blade 102.

[0071] The air outlet structure includes an air outlet shell having an air inlet side and an air outlet side, the outer blade 101 is arranged near the air outlet side, the damper 103 is arranged near the air inlet side, and the inner blade 102 is arranged between the outer blade 101 and the damper 103; the first direction is perpendicular to the second direction and the outer blade 101 is a horizontal blade, and the inner blade 102 is a vertical blade; for easy installation, the air outlet 1 shell includes a first shell and a second shell.

[0072] Preferably, the control structure 2 includes a first transmission structure 202, which includes a driving member 2021 driven by the universal rotation of the operating member 201, and a swing arm 2022 driven to rotate by the driving member 2021; the swing arm 2022 is connected to the outer wall of the driving member 2021 and the two can slide in at least two directions; the swing arm 2022 includes an outer blade swing arm 2022-1 for driving the outer blade 101 and an inner blade swing arm 2022-2 for driving the inner blade 102.

[0073] By adopting the above structure, when the driving member 2021 drives the universal rotation to drive the swing arm 2022 to rotate, it can be ensured that the position of the swing arm 2022 does not shift and the control structure 2 does not get stuck.

[0074] The position where the driving member 2021 is used to drive the swing arm 2022 is called the driving position. Taking the outer blade swing arm 2022-1 as an example, if the rotation axis of the driving member 2021 during universal rotation is always parallel to or coincident with the rotation axis of the outer blade swing arm 2022-1, the driving position of the outer blade swing arm 2022-1 driven by the driving member 2021 will not be offset after the driving member 2021 rotates; however, when the rotation axis of the driving member 2021 during universal rotation is not parallel to or coincident with the axis of the shaft of the outer blade swing arm 2022-1 or the axis of the shaft of the driving member 2021 changes during rotation, the driving position of the outer blade swing arm 2022-1 driven by the driving member 2021 will be offset after the driving member 2021 rotates; therefore, the above structure is adopted, and the driving member 2021 can rotate around a certain axis at will. If the driving position of the outer blade swing arm 2022-1 is offset, the offset is completed by the sliding between the outer blade swing arm 2022-1 and the driving member 2021.

[0075] If the sliding trajectories are the same or overlap, it is regarded as sliding in one direction, such as sliding to the left and sliding to the right in the same trajectory are regarded as sliding in the same direction; or if sliding in different parallel or concentric sliding paths actually slides to the left or right, the sliding trajectories overlap and are regarded as the same direction.

[0077] With the above structure, a swing arm shaft 2023 is provided between the driving member 2021 and the swing arm 2022, so as to ensure that the driving member 2021 can drive the swing arm 2022 to rotate and the two can slide in two directions.

[0080] By adopting the above structure, the swing arm shaft 2023 can slide more smoothly between the swing arm 2022 and the driving member 2021.

[0081] Preferably, the rotation axis of the outer blade swing arm 2022-1 is perpendicular to the rotation axis of the inner blade swing arm 2022-2.

[0082] When the first slide groove 2023a and the second slide bar 2023b provided on the swing arm shaft 2023 are in a cross-shaped state, the above structure is adopted, and when the rotation axis of the driving member 2021 is parallel to or coincides with the rotation axis of the outer blade swing arm shaft 2023-1, the first slide bar 2021a on the driving member 2021 that matches the outer blade swing arm shaft 2023-1 rotates to drive the outer blade swing arm shaft 2023-1 to rotate; the first slide bar 2021a on the driving member 2021 that matches the inner blade swing arm shaft 2023-2 slides in the first slide groove 2023a in the inner blade swing arm shaft 2023-2, and the first slide bar 2021a on the driving member 2021 that matches the inner blade swing arm shaft 2023-2 does not rotate, that is, the driving member 2021 does not rotate the inner blade swing arm shaft 2023-2;

[0083] When the rotation axis of the driving member 2021 is parallel to or coincides with the rotation axis of the inner blade swing arm shaft 2023-2, the first slide bar 2021a on the driving member 2021 that matches the inner blade swing arm shaft 2023-2 rotates to drive the inner blade swing arm shaft 2023-2 to rotate; the first slide bar 2021a on the driving member 2021 that matches the outer blade swing arm shaft 2023-1 slides in the first slide groove 2023a in the outer blade swing arm shaft 2023-1, and the first slide bar 2021a on the driving member 2021 that matches the outer blade swing arm shaft 2023-1 does not rotate, that is, the driving member 2021 does not rotate the outer blade swing arm shaft 2023-1; so as to realize the separate driving of the outer blade swing arm 2022-1 or the inner blade swing arm 2022-2;

[0084] When the rotation axis of the driving member 2021 is not parallel or coincident with the rotation axis of the outer blade swing arm shaft 2023-1 and the inner blade swing arm shaft 2023-2, the first slide bar 2021a on the driving member 2021 matching the outer blade swing arm shaft 2023-1 and the inner blade swing arm shaft 2023-2 both rotate to drive the outer blade swing arm shaft 2023-1 and the inner blade swing arm shaft 2023-2 to rotate, and the first slide bar 2021a on the driving member 2021 matching the outer blade swing arm shaft 2023-1 slides in the first slide groove 2023a on the outer blade swing arm shaft 2023-1, and the outer blade swing arm shaft 2023-2 rotates. The second slide bar 2023b on the arm shaft 2023-1 slides in the second slide groove 2022a on the outer blade swing arm 2022-1; the first slide bar 2021a on the driving member 2021 that matches the inner blade swing arm shaft 2023-2 slides in the first slide groove 2023a on the inner blade swing arm shaft 2023-2, and the second slide bar 2023b on the inner blade swing arm shaft 2023-2 slides in the second slide groove 2022a on the inner blade swing arm 2022-2, to prevent the swing arm shaft 2023 mechanism from getting stuck when the outer blade swing arm 2022-1 and the inner blade swing arm 2022-2 are not offset.

[0085] Preferably, at least part of the outer wall of the driving member 2021 is an outward convex arc spherical surface, and correspondingly, at least part of the inner wall of the driving member 2021 is an inward concave arc spherical surface; the swing arm 2022 is connected to the outward convex arc spherical surface of the outer wall of the driving member 2021.

[0086] With the above structure, the convex arc-shaped spherical surface of the driving member 2021 can make the universal rotation operation of the driving member 2021 more comfortable and smooth.

[0087] Preferably, the first transmission structure 202 includes an outer blade connecting rod 2024 and an inner blade connecting rod 2025; one end of the outer blade connecting rod 2024 is connected to the ball head structure of the outer blade swing arm 2022-1, and the other end is connected to the ball head structure of one outer blade 101 in at least one outer blade 101; one end of the inner blade connecting rod 2025 is connected to the ball head structure of the inner blade swing arm 2022-2, and the other end is connected to the ball head structure of one inner blade 102 in at least one inner blade 102.

[0088] With the above structure, the outer blade connecting rod 2024 and the inner blade connecting rod 2025 are connected at both ends with a ball head structure to avoid the outer blade swing arm 2022-1 and the inner blade swing arm 2022-2 from getting stuck when driving the outer blade 101 and the inner blade 102, thereby ensuring stable and reliable operation of the control structure 2.

[0089] The inner blade 102 includes an inner blade 102 body and an inner blade crank 1021 disposed at the rotation axis of the inner blade 102 body; one end of the inner blade connecting rod 2025 is connected to the ball head structure of the inner blade crank 1021.

[0090] Preferably, the control structure 2 includes a second transmission structure 203, which includes an operating member connecting member 2031 for connecting to the operating member 201, and a damper operating connecting member 2032 for operating the damper 103, and the operating member connecting member 2031 is installed on the damper operating connecting member 2032 through a universal joint 2033.

[0091] One end of the second transmission structure 203 is used to drive the damper 103, that is, one end of the damper operating connecting member 2032 drives the damper 103, so the end driving the damper 103 is inevitably subject to certain restrictions; therefore, the above structure is adopted, and the universal rotation of the operating member 201 is realized through the universal joint 2033 between the operating member connecting member 2031 and the damper operating connecting member 2032.

[0092] Specifically, the universal joint 2033 is a cross-axis universal joint, and the universal joint 2033 is connected to the damper operating connecting member 2032 via one of the rotating shafts, and the operating member connecting member 2031 is connected to the other rotating shaft of the universal joint 2033, and the two rotating shafts of the universal joint 2033 are perpendicular to each other.

[0093] With the above structure, the operating member connecting member 2031 can rotate relative to the damper 103 connecting member around one of the rotating shafts of the universal joint 2033 or around the other rotating shaft or around two rotating shafts at the same time to realize the universal rotation of the driving member 2021.

[0094] Preferably, the second transmission structure 203 includes a damper driven gear 2034 and a damper connecting rod 2035 connected to the damper 103; the damper operating connecting piece 2032 is used to drive the damper 103 and is provided with a damper driving gear 2032a at one end thereof which is meshed with the damper driven gear 2034; the rotation axis of the damper driven gear 2034 forms an angle with the rotation axis of the damper driving gear 2032a; the non-rotating axis of the damper driven gear 2034 is connected to the ball head structure at one end of the damper connecting rod 2035, and the other end of the damper connecting rod 2035 is connected to the ball head structure of the damper 103.

[0095] With the above structure, when the operating member 201 rotates around its own axis, the rotation of the operating member 201 drives the operating member connecting member 2031, the universal joint 2033, and the damper operating connecting member 2032 to rotate, so that the damper driving gear 2032a arranged at one end of the damper operating connecting member 2032 rotates and drives the damper driven gear 2034 meshing therewith to rotate, and the damper 103 is driven to rotate by the damper connecting rod 2035 arranged between the damper driven gear 2034 and the damper 103, thereby realizing the control of the air output.

[0096] The connection between the two ends of the damper connecting rod 2035 and the damper driven gear 2034 and the damper 103 adopts a ball head structure to avoid jamming between the damper driven gear 2034, the damper connecting rod 2035 and the damper 103, thereby ensuring that the operating structure can operate stably and reliably.

[0097] Specifically, the damper operating connecting member 2032 includes a damper operating member body 2032b and a damper driving gear 2032a disposed at one end of the damper operating member body 2032b; the damper driving gear 2032a is provided with a connecting groove 2032c at the connection with the damper operating member body 2032b, and the groove wall of the connecting groove 2032c is symmetrically provided with groove openings 2032c1; the damper operating member body 2032b is provided with a connecting groove 2032c1 at the connection with the damper driving gear 2032a; The end of the connecting section 2032a is provided with a ball head 2032d matching the connecting groove 2032c, and the ball head 2032d extends outwardly on one of the rotating shafts parallel to the universal joint 2033 to have a connecting shaft 2032e matching the groove opening 2032c1; when the ball head 2032d at one end of the damper operating member body 2032b is installed in the connecting groove 2032c of the damper driving gear 2032a, the connecting shaft 2032e is inserted into the groove opening 2032c1;

[0098] When the damper operating member body 2032b rotates, the connecting shaft 2032e and the connecting groove 2032c cooperate with each other, so that the damper driving gear 2032a rotates together with the damper operating member body 2032b.

[0099] The cooperation between the connecting groove 2032c and the ball head 2032d reduces the restriction between the damper operating member body 2032b and the damper driving gear 2032a; the damper operating member body 2032b can rotate around the connecting shaft 2032e or make the two ends of the connecting shaft 2032e slide along the groove opening 2032c1 to achieve rotation around the connecting shaft 2032e perpendicular to the connecting shaft 2032e or combine the above two movement modes.

[0100] Specifically, the damper driven gear 2034 is partially provided with gear teeth, and a connecting rod connecting arm extends outward from the portion where the gear teeth are not provided, and one end of the damper connecting rod 2035 is connected to the connecting rod connecting arm ball head structure; the connecting rod connecting arm enhances the driving ability of the damper driven gear 2034.

[0101] The damper driving gear 2032a and the damper driven gear 2034 are both bevel gears.

[0102] The damper 103 includes a damper 103 body and a damper crank 1031 disposed at the rotating shaft of the damper 103 body; one end of the damper connecting rod 2035 is connected to the ball head structure of the damper crank 1031, and the connection between the damper connecting rod 2035 and the damper crank 1031 is not at the rotating shaft of the damper 103 body.

[0103] The rotation axis of the damper driven gear 2034 forms an angle with the rotation axis of the damper driving gear 2032a, and can rotate the damper 103 to the maximum extent. Specifically, the rotation axis of the damper driven gear 2034 is perpendicular to the rotation axis of the damper driving gear 2032a; the damper driven gear 2034 is rotatably mounted on the air outlet 1 housing.

[0104] Preferably, the air outlet structure includes a panel 3 and a base 4 for installing the control structure 2; the panel 3 is provided with a first opening 301 for exposing the operating member 201 and at least part of the outer wall of the driving member 2021; the panel 3 cooperates with the base 4 to form a cavity 5 for installing the control structure 2.

[0105] The cavity 5 is provided with a second opening 501 and a third opening 502 at the locations where the outer blade swing arm 2022-1 and the inner blade swing arm 2022-2 are provided. The second opening 501 and the third opening 502 are respectively used to engage the rotating shafts of the outer blade swing arm 2022-1 and the inner blade swing arm 2022-2, thereby limiting the outer blade swing arm 2022-1 and the inner blade swing arm 2022-2.

[0106] The cavity 5 is provided with a gear mounting portion 503 for mounting the damper driving gear 2032a, and a damping ring 506 is provided between the mounting shaft of the damper driving gear 2032a and the gear mounting portion 503, so that a certain operating force is required to rotate the damper driving gear 2032a.

[0107] The cavity 5 is provided with a damping block 504 at the location where the driving member 2021 is installed. The damping block 504 is in contact with the outer wall of the driving member 2021 , so that a certain operating force is required to rotate the driving member 2021 .

[0108] Preferably, the outer wall of the driving member 2021 is protruding outward to form a protrusion 2021b, and correspondingly, the inner wall of the cavity 5 is recessed to form a protrusion groove 505 matching the protrusion 2021b.

[0109] When the driving member 2021 rotates, the protrusion 2021b needs to slide along the protrusion groove 505. If the rotation direction of the driving member 2021 is inconsistent with the sliding direction of the protrusion 2021b, when the protrusion 2021b slides in the protrusion groove 505, the protrusion groove 505 will apply a force to the protrusion 2021b to make the driving member 2021 spin; at this time, the second slide bar 2023b of the swing arm shaft 2023 slides in the second groove 2022a of the rotating member to avoid the control structure 2 from getting stuck.

[0110] The protrusion 2021b and the protrusion groove 505 are provided to make the operation of the control structure 2 more stable; and the protrusion 2021b and the protrusion groove 505 can also be used for positioning. When the rotation direction of the driving member 2021 is consistent with the sliding direction of the protrusion 2021b, the control structure 2 is in a special case; generally, the protrusion 2021b is located on the bisector of the line connecting the first slide bar 2021a matched with the outer blade swing arm shaft 2023-1 and the first slide bar 2021a matched with the inner blade swing arm shaft 2023-2. At this time, when the rotation direction of the driving member 2021 is consistent with the sliding direction of the protrusion 2021b, the driving member 2021 simultaneously drives the outer blade swing arm shaft 2023-1 and the inner blade swing arm shaft 2023-2, and the rotation amplitude of the outer blade swing arm shaft 2023-1 is the same as the rotation amplitude of the inner blade swing arm shaft 2023-2.

[0111] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
